Technical Field

[0004] The present application relates to the technical field of health care equipment, and in particular to a device for removing cold air and a method for using the same, a curved double-horn flow guide, a series flow guide assembly, a nested flow guide assembly, and a flow guide. Background Art

[0005] Many common ailments we see in daily life, such as frozen shoulder and chronic cold legs, often present with symptoms like joint pain and limited mobility. These symptoms are caused by the intrusion and retention of cold energy in the body. In the cold winter months, or when temperatures plummet, insufficient protection against the cold can lead to increased vulnerability to cold. Exposure to rain or water, or excessive sweating in the wind, are also common causes of exposure. Cold, as a disease, can be categorized as external or internal. External cold refers to the external invasion of cold, which can lead to typhoid fever or internal cold. When cold damages the skin surface, suppressing the defensive Yang, this is called "typhoid fever." When cold invades the interior, damaging the Yang Qi of the internal organs, this is called "internal cold." Internal cold is a pathological reaction caused by insufficient Yang Qi, resulting in a loss of warmth. While external and internal cold are distinct, they are interconnected and mutually influential. A person with yang deficiency and internal cold is susceptible to external cold. When external cold invades the body and persists, it can often damage the body's Yang Qi, leading to internal cold.

[0006] Cold has the following characteristics: ① Cold is a Yin evil that easily damages Yang Qi: Cold is the dominant Qi of winter and is inherently Yin, making it a Yin evil. As a Yin evil, cold is most likely to damage Yang Qi. Damaged Yang Qi loses its normal warming and Qi-transforming function, manifesting as symptoms of decreased function. Therefore, when cold pathogenicity is present on the surface, damage to the superficial Yang results in aversion to cold; Wei Yang is unable to disseminate, resulting in anorexia; Yang Qi is stagnant, resulting in heat and fever. Therefore, aversion to cold, fever, and anorexia are characteristic of cold pathogenicity on the surface. When cold pathogenicity invades the interior, damaging the Yang of the spleen and stomach, it disrupts its transport and transformation functions, resulting in symptoms such as cold pain in the abdomen, vomiting, and diarrhea. When spleen and kidney Yang are deficient and unable to warm and transport Qi, symptoms such as aversion to cold, cold limbs, cold pain in the lower back, edema, ascites, clear diarrhea, and long, clear urination may occur. Therefore, the Suwen Zhizhen Yao Da Lun states: "All diseases characterized by clear, cool fluids are attributed to cold."

[0007] ② Coldness causes pain due to stagnation: Stagnation refers to blockage and obstruction. The circulation of qi and blood in the human body depends on the warmth of yang and harmony. Therefore, when qi and blood encounter cold, they become stagnant and blocked, and this blockage causes pain. "Pain is caused by excess cold, and pain arises from the presence of cold," states the Suwen (Suwen) Treatise on Bi. Therefore, coldness causes pain. Regarding the mechanism of pain caused by cold, the Suwen (Suwen) Treatise on Pain states, "Cold qi enters the meridians, causing delays and stagnation. If it invades the external meridians, blood is depleted; if it invades the internal meridians, qi is blocked, resulting in sudden pain." It further states, "If cold qi invades the external meridians, the pulse becomes cold. A cold pulse curls up, and a curled pulse becomes constricted and tense. A constricted pulse pulls the small collaterals outward, causing sudden pain." Therefore, pain is one of the characteristics of cold pathogens. If cold pathogens attack the exterior, pain in the head and body occurs. If they invade the meridians, pain in the joints may occur, and even pain in the joints may lead to difficulty bending and stretching, and numbness. If they invade the internal organs, pain in the abdomen may occur.

[0008] ③ Cold astringency: Astringency means contraction and traction. Cold astringency is another manifestation of stagnation of cold pathogenicity. "Suwen: Jutonglun" states, "Cold causes Qi to contract." Qi contraction refers to the contraction and stagnation of Qi. Clinical manifestations include: Cold invading the blood vessels can cause meridian contraction, stagnation of Qi and blood flow, pain, and a tight pulse. Cold invading the skin and pores can cause contraction of the pores and obstruction of Wei Yang. Contraction of the pores causes aversion to cold and lack of sweating, while stagnation of Wei Yang causes fever. Cold invading the meridians and joints can cause meridian contraction, difficulty flexing and extending the limbs, or numbness due to cold.

[0009] There are many ways to remove cold in Traditional Chinese Medicine, mainly including doing health exercises, exercise therapy such as Tai Chi, taking warming and cold-dispelling medicines as internal treatment, and external treatment methods such as foot soaking, heat lamps, moxibustion, massage, and scraping.

[0010] 1) Exercise Therapy: Exercise can mobilize the body's Yang Qi. Sufficient Yang Qi can promote the circulation of Qi and blood, thereby accelerating the flow of Qi and blood throughout the body's tissues and organs. Smooth Qi and blood circulation can increase the body's warming effect, thereby achieving the effect of warming Yang and dispersing cold. Common exercises include Yi Jin Jing (Emperor's Tendon and Bones) and Tai Chi, suitable for people of all ages. Advantages of exercise therapy: It is simple and convenient, can be practiced at any time, and can be completed by one person without the need for equipment. Disadvantages: It is slow to take effect, requires long-term persistence, and has little to no short-term effect. Improper exercise can also cause damage to the body.

[0011] 2) Internal Treatment: Cold can be categorized as internal or external. Internal cold is caused by insufficient Yang Qi, resulting from physical weakness and chronic illness. External cold is caused by external exposure to cold and dampness, such as wind, rain, or cold weather, or by excessive consumption of cold foods, which damages Yang Qi. This leads to symptoms of coldness entering the body, such as cold hands and feet, and a chilly body. Traditional Chinese Medicine often says that Yang can overcome Yin, meaning that abundant Yang Qi can warm the body and dispel cold. In clinical practice, Yang-warming and cold-dispelling herbs are often used to dispel cold, such as Fuzi Lizhong Pills, Guipi Pills, and Jinkui Shenqi Pills. Internal treatment primarily involves the use of Chinese medicine. Its advantage is that it addresses both internal and external cold, addressing both internal and external cold. However, its disadvantages are: ① The formulation of Chinese medicine varies from person to person, and the same formula may not be suitable for everyone; ② It requires professional guidance and can sometimes have limitations; and ③ The effectiveness of Chinese medicine generally lasts for a long time, making it difficult to see results in the short term.

[0012] 3) External treatment: External treatments are designed to rapidly raise body temperature through the conduction and radiation of heat energy, thereby dispelling the cold. For example, foot soaking can directly transmit the temperature of hot water to the body; heat lamps and moxibustion can radiate heat energy to the body through the air, dispelling the cold from the outside in; massage and scraping can increase body surface temperature through frictional heat generation. These external treatments utilize the principle of heat dissipating cold to achieve the purpose of dispersing cold and warming yang; cupping can use negative pressure to draw the cold out of the body. In addition, some special techniques can also achieve the purpose of expelling cold, such as acupuncture's burning mountain fire, opening and closing to replenish and drain, and moxibustion's pecking moxibustion.

[0013] External treatment methods in Traditional Chinese Medicine include instrument therapy and manual therapy. The advantages of instrument therapy are: it is easy to use, such as foot baths and heat lamps, which can deliver heat to the human body, and there is no invasive operation, high safety, few side effects, and certain therapeutic effects. Most operations are completed automatically by the instrument, and the manual operation part is generally relatively simple, and ordinary users can quickly get started. The disadvantages of instrument therapy are: current instruments all deliver heat into the human body to achieve the purpose of dispelling cold, but do not guide the cold air out of the body. In this way, although some of the cold air will be driven out of the body by the heat, most of the cold air will be entangled with the heat and wrapped in the human body, preventing the cold air from further dissipating from the body. From the long-term effect point of view, frequent use of such products will wrap the cold air deep in the human body and make it more difficult to dispel.

[0014] Advantages of manual therapy: It can be used for tonification and purgation through manipulation, with targeted treatment tailored to each individual, resulting in rapid and significant results. Disadvantages of manual therapy: It requires a certain level of expertise and is not widely available. Furthermore, it requires regular visits to a hospital or clinic for treatment, making it difficult to perform at home, which can be inconvenient.

[0015] In fact, among manual physical therapy methods, there's a moxibustion technique that simulates a sparrow's pecking, which inherently has the ability to draw cold out of the body. This moxibustion technique differs from conventional moxibustion methods in that it involves holding the moxa stick in place and applying it in a manner similar to a sparrow's pecking motion, moving it up and down, moving closer and farther away. This technique, like a sparrow pecking repeatedly, earns it the name "sparrow pecking moxibustion." This up-and-down motion draws cold out of the body in waves, a process known as "drainage." Its efficacy is significantly superior to conventional moxibustion methods. However, sparrow pecking moxibustion requires a high level of skill from the practitioner, especially as it requires repeated repetitions, making it more dependent on the practitioner's subjective perception. Therefore, sparrow pecking moxibustion is not an objective method, lacking objective operating standards, making it difficult to promote. Currently, no other objective, easy-to-use method exists to expel cold from the body. Therefore, there is an urgent need for an objective, easy-to-use device and method for its use that can expel cold from the body.

[0016] Summary of the Invention

[0017] The purpose of this application is to provide an objective and easy-to-operate cold-removing device and its use method, a curved double-horn deflector, a series deflector assembly, a nested deflector assembly and a deflector that can expel cold air from the human body.

[0018] The present application discloses a device for dispelling cold air, which includes a mobile component, an energy source fixing structure, a diversion module and a control module. The energy source fixing structure is arranged on the mobile component for fixing the energy source; the diversion module is arranged on the mobile component, and both ends of the diversion module are open and the interior is hollow to form a channel, one end of the channel faces the energy source, and the other end of the channel faces the user to be dispelled cold air; the control module is connected to the mobile component, and is used to drive the mobile component to drive the energy source fixing structure and the diversion module to move a first preset distance away from the user to be dispelled cold air.

[0019] Optionally, the diversion module includes at least a first speaker and a second speaker, wherein the large end of the first speaker faces the energy source fixed structure, and the large end of the second speaker faces the user to be dispelled cold air; the first speaker and the second speaker form the channel; the large end of the first speaker faces the energy source fixed structure, and the large end of the second speaker faces the user to be dispelled cold air; the first speaker includes a large end and a small end, and the second speaker includes a large end and a small end, the diameter of the large end of the first speaker is larger than the diameter of the small end of the first speaker, and the diameter of the large end of the second speaker is larger than the diameter of the small end of the second speaker. This solution includes at least one first speaker and one second speaker, and the two large ends of the channel formed face the human body and the energy source respectively, so that after the human body cold air is gathered in the channel of the first speaker, it is guided by the channel of the second speaker and diffused toward the energy source; this diffusion process further amplifies the guiding effect of the cold air, attracting more cold air to pass through the first speaker, that is, the cold air is accelerated after passing through the first speaker. The guide is then driven to enter the first speaker at an accelerated speed, greatly improving the efficiency of the cold air extraction, and even drawing out the cold air from deeper layers of the human body.

[0020] Optionally, the diversion module takes the channel extension direction as the central axis and presents an axisymmetric structure; the inner walls of the first speaker and the second speaker are arcs along the cross-sectional line on the central axis, and the arcs are concave toward the central axis. . In this solution, the inner walls of the first speaker and the second speaker adopt concave arc surfaces. After the cold air enters the large mouth end of the first speaker from the human body, it gradually gathers under the guidance of the arc surface without any sudden changes in the middle; at the same time, under the guidance of the arc surface, the cold air naturally transitions from the small mouth end of the first speaker to the second speaker, and gradually diffuses toward the energy source under the guidance of the arc surface of the second speaker. In this way, the entire cold air guiding process tends to be smooth, and the cold air can establish a more stable connection with the energy source.

[0021] Optionally, the inner walls of the first horn and the second horn have a cross-sectional line on the central axis that is an arc, and the curvature of the arc of the first horn and the second horn gradually increases or first increases and then decreases from the large-mouth end to the small-mouth end.

[0022] Optionally, the tangent of the arc corresponding to the endpoint of the large mouth of the first horn is perpendicular or tends to be perpendicular to the central axis, and the tangent of the arc corresponding to the endpoint of the large mouth of the second horn is perpendicular or tends to be perpendicular to the central axis, that is, the large mouth of the first horn or the second horn tends to be close to the plane perpendicular to the central axis. In this way, from the perspective of the effect of guiding cold air, the large mouth can cover the cold air emitted from the human body as much as possible, and the guiding effect is better.

[0023] Optionally, after waiting for a first preset time, the control module drives the moving assembly to move the energy source fixing structure and the diversion module a first preset distance away from the user to be de-cold-treated. In this embodiment, after waiting for the first preset time, a more stable connection can be established between the energy source and the cold air of the user to be de-cold-treated. Traditional Chinese medicine's sparrow pecking moxibustion also establishes a connection between the cold air and the energy source before expelling the cold air, essentially the same as in this embodiment. Due to a lack of understanding of sparrow pecking moxibustion, the conventional wisdom is to first place the moxa stick close to the body part and then quickly remove it, similar to pulling a plug, to expel the cold air, removing it a small amount at a time. This requires multiple round trips of movement. With existing sparrow pecking moxibustion techniques, there's no intention to pause as the energy source approaches the user to be de-cold-treated. Instead, the moxa stick primarily relies on establishing contact as it approaches the user. Furthermore, sparrow pecking moxibustion approaches quickly and doesn't pause, resulting in an unstable connection. Therefore, if the moxa stick is removed slowly, the cold air released is quite limited. Therefore, since the connection established by the sparrow pecking moxibustion is unstable, the sparrow pecking moxibustion needs to be pulled out quickly during the process of removal in order to bring out a certain amount of cold air.

[0024] The difference between this solution and sparrow pecking moxibustion is that the inventor discovered in practice that after an energy source such as moxa sticks is aimed at a user to remove cold air at close range, a more stable connection between the energy source and the cold air can be established by waiting for a first preset time. In this way, no matter how fast or slow the moving component moves, the connection between the cold air and the energy source is relatively difficult to disconnect.

[0025] Optionally, the first preset time is 10-300s, and the first preset distance is 50-200cm. Furthermore, the first preset time is 10-60s. In this solution, if the first preset time is too short, the established connection is relatively unstable; if the time is too long, it is easy to establish an equilibrium state, that is, the trend of cold air extraction is weakened, and the connection is easily interrupted when the energy source moves. It has been verified that the first preset time of 10-60s is more appropriate and is suitable for most energy sources.

[0026] Optionally, after the control module drives the mobile component to move the energy source fixing structure and the diversion module away from the user to be treated for the first preset distance, it controls the mobile component to remain for a second preset time. In this solution, after remaining for the second preset time, the energy source is removed. At this time, the connection between the cold air and the energy source has stabilized. At this time, removing the energy source allows the cold air to directly connect with the energy source, allowing the cold air to be more naturally drawn out of the body, further drawing out the cold air and consolidating the treatment results. Of course, it is also feasible to keep the energy source stationary and remove the diversion module.

[0027] Optionally, the second preset time is 10-300s. Further, the second preset time is 10-60s.

[0028] Optionally, the distance between the energy source fixing structure and the flow guide module is 5-30 cm.

[0029] Optionally, the control module drives the moving assembly to move the energy source fixing structure and the diversion module at a uniform speed of 2-5 mm / s for a first preset distance away from the user to be de-cold-expelled. In this solution, the speed remains constant during the movement, which is conducive to stabilizing the connection between the energy source and the cold air.

[0030] Optionally, during one use of the cold-removing device, the energy source fixing structure and the diversion module only move once in a direction away from the user to be cold-removed, and do not return.

[0031] Optionally, the cold-dispelling device further includes a voice function module. When the control module drives the mobile component to move the energy source fixed structure and the diversion module away from the user to be treated for cold for a first preset distance, and controls the mobile component to remain for a second preset time, the voice function module issues a voice reminder to remind the user to end the treatment. In this solution, during use of the cold-dispelling device, the energy source and diversion module only move in a direction away from the user to be treated for cold, and do not return. A voice reminder is also issued after use, making it more intelligent.

[0032] Optionally, the diversion module is a curved double-horn diversion piece, the channel of the curved double-horn diversion piece is double-horn-shaped, and the double-horn diversion piece includes a first horn and a second horn, the first horn includes a large mouth end and a small mouth end, the second horn includes a large mouth end and a small mouth end, the diameter of the large mouth end of the first horn is larger than the diameter of the small mouth end of the first horn, and the diameter of the large mouth end of the second horn is larger than the diameter of the small mouth end of the second horn; the small mouth end of the first horn is connected with the small mouth end of the second horn to form the double-horn-shaped channel; the large mouth end of the first horn faces the energy source fixing structure, and the large mouth end of the second horn faces the user to be dispelled cold air; the cross-sectional line of the inner wall of the first horn and the second horn along the central axis of the curved double-horn diversion piece is an arc, and the arc is concave toward the central axis. In this solution, the inner walls of the first and second speakers adopt concave arc surfaces. After the cold air enters the large mouth end of the first speaker from the human body, it gradually gathers under the guidance of the arc surface, without any sudden change in the middle. At the same time, under the guidance of the arc surface, the cold air naturally transitions from the small mouth end of the first speaker to the second speaker, and gradually diffuses toward the energy source under the guidance of the arc surface of the second speaker. In this way, the entire cold air guidance process tends to be smooth, and the cold air can establish a more stable connection with the energy source.

[0033] Optionally, the diversion module is a series diversion component, one end of the series diversion component is facing the energy source fixed structure, and the other end of the series diversion component is facing the user to be cleared of cold air; the series diversion component includes at least two double-horn body diversion pieces with gradual curvature arranged in parallel, and the channel of the double-horn body diversion piece with gradual curvature is double-horn shaped, and the double-horn body diversion piece with gradual curvature includes a first horn and a second horn symmetrically arranged, the first horn includes a large mouth end and a small mouth end, the second horn includes a large mouth end and a small mouth end, and the diameter of the large mouth end of the first horn is larger than the diameter of the small mouth end of the first horn. diameter, the diameter of the large-mouth end of the second horn is larger than the diameter of the small-mouth end of the second horn; the small-mouth end of the first horn is connected with the small-mouth end of the second horn to form the double-horn-shaped channel; the cross-sectional lines of the inner walls of the first horn and the second horn along the central axis of the double-horn-body flow guide with gradual curvature are arcs, and the arcs are concave toward the central axis; in the series flow guide assembly, the large-mouth ends of two adjacent double-horn-body flow guides with gradual curvature are arranged opposite to each other; and along the central axis of the double-horn-body flow guide with gradual curvature, the large-mouth ends of two adjacent double-horn-body flow guides with gradual curvature at least partially overlap.

[0034] In this solution, a series guide assembly is formed by at least two curvature gradient double-horn body guide pieces connected in series. After the cold air is first gathered by the curvature gradient double-horn body guide piece of the previous stage, the curvature gradient double-horn body guide piece of the next stage will gather the scattered cold air from the curvature gradient double-horn body guide piece of the previous stage for a second time. After the two gatherings, the cold air has a stronger tendency to move along the axis toward the energy source, making it less likely for the cold air to attenuate during movement. Compared with a single curvature gradient double-horn body guide piece, the cold air that passes through the series guide assembly in this solution is gathered multiple times, and the final amount of scattered cold air is less, and the connection between the cold air and the energy source is stronger, resulting in better stability. During the movement process, the secondary gathering of the curvature gradient double-horn body guide piece of the next stage has a stabilizing effect on the curvature gradient double-horn body guide piece of the previous stage. The curvature gradient double-horn body guide piece of the previous stage is less affected by changes in the external environment and is more stable during movement.

[0035] Optionally, the diversion module is a nested diversion component, one end of the nested diversion component faces the energy source fixed structure, and the other end of the nested diversion component faces the user to be cleared of cold air; the nested diversion component includes at least two levels of curvature gradient double-horn body diversion parts, the sizes of the curvature gradient double-horn body diversion parts at different levels are different, and the curvature gradient double-horn body diversion part of the lower level is nested in the curvature gradient double-horn body diversion part of the upper level; the channel of the curvature gradient double-horn body diversion part is double-horn shaped, and the curvature gradient double-horn body diversion part includes a first horn and a second horn symmetrically arranged, the first horn includes a large mouth end and a small mouth end, and the second horn includes a large mouth end and a small mouth end Mouth end, the diameter of the large mouth end of the first horn is larger than the diameter of the small mouth end of the first horn, and the diameter of the large mouth end of the second horn is larger than the diameter of the small mouth end of the second horn; the small mouth end of the first horn is connected with the small mouth end of the second horn to form the double-horn-shaped channel; the section line of the inner wall of the first horn along the central axis of the double-horn body guide member with gradual curvature is an arc, and the arc is concave toward the central axis; in the nested guide assembly, viewed along the central axis direction of the double-horn body guide member with gradual curvature of the upper level, the through holes of the double-horn body guide member with gradual curvature of the upper level and the double-horn body guide member with gradual curvature of the lower level at the narrowest part of the channel at least partially overlap.

[0036] In this solution, a nested guide assembly is adopted in which multiple levels of curvature gradient double-horn body guide pieces are nested. Since the curvature gradient double-horn body guide piece of the upper level has a larger opening and a wider coverage area, it can gather more cold air; and the curvature gradient double-horn body guide piece of the lower level has a smaller opening, so that the cold air gathered through the opening of the curvature gradient double-horn body guide piece of the upper level enters the small-sized curvature gradient double-horn body guide piece (the curvature gradient double-horn body guide piece of the lower level). Through secondary guidance, the attraction of the cold air can be enhanced, allowing the cold air to pass through the nested guide assembly more stably; at the same time, the center of the curvature gradient double-horn body guide piece of the lower level is narrower, which can make the cold air more concentrated. After adopting the nested guide assembly, the attraction formed by at least two layers of guidance brought by the upper-level curvature gradient double-horn guide piece and the lower-level curvature gradient double-horn guide piece is sufficient to allow more concentrated cold air to pass through the central through hole of the lower-level curvature gradient double-horn guide piece, thereby driving the deeper cold air of the human body out into the nested guide assembly, which can better clear the root cause of the cold air and improve the health level of the human body.

[0037] Optionally, the diverter module is a diverter, one end of the diverter faces the energy source fixed structure, and the other end of the diverter faces the user to be rid of cold air; the diverter includes at least one nested diverter component and at least one independent curvature gradient double-horn body diverter, one end of the curvature gradient double-horn body diverter and one end of the nested diverter component are arranged relative to each other; or, the diverter includes at least two nested diverter components, and one end of adjacent nested diverter components are arranged relative to each other; the nested diverter component includes at least two levels of curvature gradient double-horn body diverters, and the sizes of curvature gradient double-horn body diverters at different levels are different, and the curvature gradient double-horn body diverter of the lower level is nested in the curvature gradient double-horn body diverter of the upper level; the channel of the curvature gradient double-horn body diverter is double-horn shaped, and the curvature gradient double-horn The body guide member includes a first horn and a second horn symmetrically arranged, the first horn includes a large mouth end and a small mouth end, the second horn includes a large mouth end and a small mouth end, the diameter of the large mouth end of the first horn is larger than the diameter of the small mouth end of the first horn, and the diameter of the large mouth end of the second horn is larger than the diameter of the small mouth end of the second horn; the small mouth end of the first horn is connected with the small mouth end of the second horn to form the double-horn-shaped channel; the section line of the inner wall of the first horn along the central axis of the double-horn body guide member with gradual curvature is an arc, and the arc is concave toward the central axis; in the nested guide assembly, viewed along the central axis direction of the double-horn body guide member with gradual curvature, the through holes of the double-horn body guide member with gradual curvature at the upper level and the double-horn body guide member with gradual curvature at the lower level at the narrowest part of the channel at least partially overlap.

[0038] In this solution, by placing two or more nested guide components in parallel, or placing nested guide components and curvature gradient double-horn guide pieces in parallel, the cold air can be converged twice or more, and the tendency of the cold air to move toward the energy source along the axis direction is stronger, making it less likely for the cold air to attenuate during the movement. Compared with a single nested guide component, the cold air after the series design in this solution is converged multiple times, and the final amount of cold air that is scattered is less, the connection between the cold air and the energy source is stronger, and the stability is better. During the movement process, the secondary convergence of the latter-stage nested guide component or curvature gradient double-horn guide piece has a stabilizing effect on the former-stage nested guide component or curvature gradient double-horn guide piece, and the former-stage nested guide component or curvature gradient double-horn guide piece is less affected by changes in the external environment and is more stable during the movement. In summary, the use of a deflector can enhance the guiding effect of the cold air, while stabilizing the connection between the cold air and the energy source during the movement, and improving the effect of removing the cold air.

[0040] Optionally, the moving assembly further includes a conveyor belt, a rotating wheel and a lifting gallows, the motor drives the wheel to rotate via the conveyor belt, the bottom end of the lifting gallows is fixed to the frame, and the top end is fixed to the mounting platform; the rotating wheel is fixed to the front end of the frame, and is connected to the bottom end of the lifting gallows via a screw rod, so as to control the rise and fall of the mounting platform.

[0041] Optionally, the mobile component includes a bracket, a trolley and a cross bar, the trolley adopts a tricycle chassis, the bracket is a liftable tripod, the cross bar is provided above the liftable tripod, the cross bar has three clamps, and the fixed position of the clamps on the cross bar is adjustable; the first clamp is used to fix the cross bar to the liftable tripod; the second clamp is used to fix the energy source fixing structure, and the third clamp is used to fix the diversion bracket, and the diversion module is fixed on the diversion bracket.

[0043] The lifting mechanism is a pair of fixedly mounted on two ends of the sled, and the fixing mechanism is a pair of fixedly mounted on two ends of the sled, and the fixing mechanism can be effectively prevented from slipping off the two ends of the sled and getting lost in the interlocking action of the boot.

[0044] Optionally, the energy source includes one or more of moxa products, essential oils or light sources.

[0045] The present application also discloses a curved double-horn flow guide, wherein both ends of the curved double-horn flow guide are open and the interior is hollow to form a channel, the flow guide module is a curved double-horn flow guide, and the channel of the curved double-horn flow guide is double-horn-shaped, the double-horn flow guide comprises a first horn and a second horn, the first horn comprises a large mouth end and a small mouth end, the second horn comprises a large mouth end and a small mouth end, the diameter of the large mouth end of the first horn is larger than the diameter of the small mouth end of the first horn, and the diameter of the large mouth end of the second horn is larger than the diameter of the small mouth end of the second horn; the small mouth end of the first horn is connected to the small mouth end of the second horn to form the double-horn-shaped channel; the cross-sectional line of the inner wall of the first horn and the second horn along the central axis of the curved double-horn flow guide is an arc, and the arc is concave toward the central axis.

[0046] Optionally, the curved double-horn flow guide is a double-horn flow guide with a gradual curvature, and the cross-sectional lines of the inner walls of the first horn and the second horn along the central axis of the double-horn flow guide with a gradual curvature are arcs, and the curvature of the arcs of the first horn and the second horn increases from the large-mouth end to the small-mouth end.

[0047] In this solution, the greater the curvature of the inner wall of the gradually varying curvature dual-flare flow guide, the stronger its ability to guide cold air. After the cold air enters the gradually varying curvature dual-flare flow guide from the large opening of the first flare, it is guided by the inner wall of the first flare and gradually accelerates, quickly passing through the small opening of the first flare and entering the second flare, preventing the cold air from accumulating in the center of the gradually varying curvature dual-flare flow guide. After the cold air enters the small opening of the second flare, it is further accelerated by the inner wall of the second flare, allowing it to pass through the small opening of the first flare and enter the second flare more quickly. The increased speed of the cold air passing through the small opening of the first flare, in turn, attracts more cold air into the first flare, enhancing the gradually varying curvature dual-flare flow guide's ability to guide cold air. After entering the second flare, the cold air, guided by the inner wall of the second flare, gradually slows its acceleration from the small opening of the second flare toward the large opening, preventing a break in the connection between the cold air and the energy source and enhancing the stability of the connection between the cold air and the energy source. Therefore, the use of a double-flared guide piece with a gradually changing curvature can further enhance the cold air guiding ability of the curved double-flared guide piece on the basis of stabilizing the energy source and the stability of the cold air connection. The cold air guiding effect is better than the curved double-flared guide piece with a fixed arc curvature.

[0048] Optionally, the curved double-horn body flow guide is a double-horn body flow guide with a gradual curvature, and the cross-sectional line of the inner wall of the first horn and the second horn along the central axis of the double-horn body flow guide with a gradual curvature is an arc line. From the large-mouth end to the small-mouth end of the first horn and the second horn, the curvature of the arc line of the first horn and the second horn first increases and then decreases.

[0049] Optionally, the tangent of the arc corresponding to the endpoint of the large mouth end of the first horn is perpendicular or tends to be perpendicular to the central axis, and the tangent of the arc corresponding to the endpoint of the large mouth end of the second horn is perpendicular or tends to be perpendicular to the central axis.

[0050] Optionally, the tangent line of the arc corresponding to the endpoint of the small mouth end of the first horn is parallel or tends to be parallel to the central axis, and the tangent line of the arc corresponding to the endpoint of the small mouth end of the second horn is parallel or tends to be parallel to the central axis.

[0051] In this solution, the diameter of the large openings at both ends of the gradually tapering double-flared flow guide tends to be infinitely large, while the diameter of the narrowest point in the middle is infinitely small. This is the goal of the present invention. Furthermore, the wall thickness of the gradually tapering double-flared flow guide is minimized, and the difference in wall thickness between different locations of the gradually tapering double-flared flow guide is minimized. Under current manufacturing conditions, it is relatively easy to enlarge the large openings. However, this increases the volume and weight of the product. While maintaining the thinnest wall thickness, the diameter of the narrowest point in the middle of the gradually tapering double-flared flow guide must be sufficiently large to ensure structural stability. Otherwise, the weight of the product will cause the gradually tapering double-flared flow guide to break in the middle. Therefore, when there is a preset diameter at the small mouth end, the arcs of the first horn and the second horn tend to be parallel to the central axis toward the small mouth end, so that the narrowest part in the middle of the double horn body with a gradual curvature maintains a trend of infinitely approaching the preset diameter. In this way, when the cold air passes through the narrowest part in the middle of the double horn body guide member with a gradual curvature, it will also tend to gather towards the central axis position, thereby improving the ability to guide the cold air.

[0052] To reduce manufacturing costs, the two large openings of the gradually changing curvature double-flared deflector can be aligned perpendicular to the central axis, thereby trapping the majority of the cold air. Verification has shown that this gradually changing curvature double-flared deflector is still superior to curved double-flared deflectors with a fixed curvature, achieving a relatively ideal cold air guidance effect. The tangent of the small opening is parallel to the central axis, ensuring a smooth transition of cold air through the narrowest part of the gradually changing curvature double-flared deflector.

[0053] Optionally, the small-mouth end of the first horn is directly connected to the small-mouth end of the second horn. In this solution, the small-mouth ends of the first horn and the second horn are directly connected, and the flow guide is more compact in structure.

[0054] Optionally, the connection between the small end of the first horn and the small end of the second horn is smoothly transitioned. In this solution, the connection between the two small ends is smoothly transitioned, and there is no sudden change in the process of cold air entering the second horn from the first horn, and the cold air guiding process is smoother and less likely to be interrupted.

[0055] Optionally, the first speaker and the second speaker are of the same size and shape; the first speaker and the second speaker are axially symmetrical. In this solution, a symmetrical double speaker structure is adopted, the second speaker and the first speaker are matched in their ability to gather cold air, the process of drawing out cold air during movement is consistent, and the connection between cold air and energy source is more stable and not easily interrupted. If there is inconsistency, two situations will occur: when the guiding ability of the second speaker channel exceeds that of the first speaker channel, the guiding ability of the first speaker channel cannot keep up, and during movement, the cold air cannot be effectively introduced into the first speaker channel, and the connection between the cold air and the energy source is easily severed. Another situation is that the guiding ability of the second speaker channel is lower than that of the first speaker channel, and the cold air is easily retained in the center of the double speaker body guide, and the cold air cannot smoothly pass through the curved double speaker body guide, and the guiding effect will be greatly reduced. During movement, the connection between the cold air and the energy source is also easily severed.

[0056] Optionally, the curved double-horn body flow guide includes a throat, which is hollow inside and open at both ends; the two ends of the throat are respectively connected to the small mouth end of the first horn and the small mouth end of the second horn; the small mouth end of the first horn and the small mouth end of the second horn are smoothly transitioned to the connection between the throat and the neck. In this solution, the throat can be cylindrical with a uniform internal diameter, and the cross section is a straight line parallel to the central axis, so that the cold air can transition from the first horn to the second horn along the direction parallel to the central axis, and the cold air guiding effect is better. And the cylindrical throat makes it convenient for the clamp to fix the double-horn body flow guide from the middle. Since the interior of the first horn and the second horn is a concave arc surface, the length of the throat is shortened as much as possible, so that the process of guiding the cold air from the first horn, the throat to the second horn will be smoother, which is conducive to improving the cold air guiding effect. Of course, the throat can also adopt an inward-concave arc surface, that is, the cross-section of the throat is a concave arc; the curvature change law of the arc surface is different from that of the first speaker and the second speaker, so that the cold air guidance process in the guide member will be smoother, further improving the cold air guiding effect.

[0057] Optionally, the inner wall of the curved double-horn body flow guide is provided with a plurality of guide warps, and the plurality of guide warps extend from the large mouth end of the first horn to the large mouth end of the second horn body; on the same vertical plane of the central axis of the curved double-horn body flow guide, the spacing between two adjacent guide warps is equal. In this solution, the guiding warps are used to further improve the guiding effect of the energy source on the cold air in the human body, so that after the cold air is drawn out of the human body, it is instructed and guided by the guide warps, and can pass through the flow guide better and faster, thereby improving the discharge efficiency of the cold air. The equal spacing between the guide warps can ensure that the dual-horn body flow guide has equal guiding effect in all directions, and the cold air guiding process is smoother.

[0058] Optionally, the inner wall of the curved double-horn flow guide is further provided with a plurality of guide wefts, which surround the central axis of the curved double-horn flow guide and are arranged at intervals along the central axis.

[0059] Optionally, the distance between adjacent guide wefts gradually increases along the extension direction from the center of the double-horn body guide piece to both ends. In this solution, the smaller the distance between adjacent guide wefts, the stronger the ability to attract cold air; conversely, the weaker it is. In order to allow a smooth transition in the cold air guiding process, the attraction of the curved double-horn body guide piece to the cold air should increase from both ends to the center. In this way, after the cold air comes out of the human body, it enters the guide piece in a gradually accelerated manner, and then is guided to the energy source in a gradually decelerated manner, making the process of drawing out the cold air more stable. It has been proven that the combination of guide warps and guide wefts can improve the stability of the curved double-horn body guide piece in guiding cold air, while allowing the cold air to pass through the curved double-horn body guide piece more smoothly.

[0060] Optionally, the outer wall of the curved double-horn flow guide is concave in the direction close to the central axis, and the wall thickness of the curved double-horn flow guide increases from the two ends of the curved double-horn flow guide toward the center. In this solution, the shape of the outer wall of the curved double-horn flow guide is roughly the same as the shape of the inner wall of the curved double-horn flow guide. The flow guide is large at both ends and thin in the middle, which is structurally unstable. The closer to the edge, the easier it is to deform. If the wall thickness is increased as a whole, the production cost of the curved double-horn flow guide will increase; if the edges are made thicker and the middle is made thinner, it will become heavy at both ends and light in the middle, which may easily cause the curved double-horn flow guide to break in the middle. Therefore, by gradually increasing the wall thickness of the curved double-horn flow guide from the edge to the middle, the degree of deformation of the edge part can be effectively reduced, and the structural strength of the middle part of the curved double-horn flow guide can be improved to prevent breakage; at the same time, compared with the method of increasing the wall thickness as a whole, the cost is lower.

[0061] Optionally, the outer wall of the curved double-flared flow guide is recessed toward the central axis, and the wall thickness of the curved double-flared flow guide is uniform at any position on the curved double-flared flow guide. In this embodiment, the wall thickness of the curved double-flared flow guide is uniform, and along any cross-section passing through the central axis, the arc of the outer wall of the curved double-flared flow guide is completely consistent with the arc of the inner wall of the curved double-flared flow guide; this consistency inside and outside can enhance the ability to guide cold air.

[0062] The present application also discloses a series flow guide component, wherein both ends of the series flow guide component are open and the interior is hollow to form a channel, and the series flow guide component includes at least two double-horn flow guide pieces with gradual curvature arranged in parallel, and the channel of the double-horn flow guide piece with gradual curvature is in the shape of a double horn, and the double-horn flow guide piece with gradual curvature includes a first horn and a second horn that are symmetrically arranged, the first horn includes a large-mouth end and a small-mouth end, the second horn includes a large-mouth end and a small-mouth end, the diameter of the large-mouth end of the first horn is larger than the diameter of the small-mouth end of the first horn, and the diameter of the second horn is larger than the diameter of the small-mouth end of the first horn. The diameter of the large mouth end is larger than the diameter of the small mouth end of the second horn; the small mouth end of the first horn is connected to the small mouth end of the second horn to form the double-horn-shaped channel; the cross-sectional line of the inner wall of the first horn along the central axis of the double-horn body flow guide with gradual curvature is an arc, and the arc is concave toward the central axis; in the series flow guide assembly, the large mouth ends of two adjacent double-horn body flow guides with gradual curvature are arranged opposite to each other; and along the central axis of the double-horn body flow guide with gradual curvature, the large mouth ends of two adjacent double-horn body flow guides with gradual curvature at least partially overlap.

[0063] In this solution, a series guide assembly is formed by at least two curvature gradient double-horn body guide pieces connected in series. After the cold air is first gathered by the curvature gradient double-horn body guide piece of the previous stage, the curvature gradient double-horn body guide piece of the next stage will gather the scattered cold air from the curvature gradient double-horn body guide piece of the previous stage for a second time. After the two gatherings, the cold air has a stronger tendency to move along the axis toward the energy source, making it less likely for the cold air to attenuate during movement. Compared with a single curvature gradient double-horn body guide piece, the cold air that passes through the series guide assembly in this solution is gathered multiple times, and the final amount of scattered cold air is less, and the connection between the cold air and the energy source is stronger, resulting in better stability. During the movement process, the secondary gathering of the curvature gradient double-horn body guide piece of the next stage has a stabilizing effect on the curvature gradient double-horn body guide piece of the previous stage. The curvature gradient double-horn body guide piece of the previous stage is less affected by changes in the external environment and is more stable during movement. In summary, the use of series guide components can enhance the guiding effect of cold air, while stabilizing the connection between cold air and energy source during movement, thereby improving the effect of removing cold air.

[0064] Optionally, the cross-sectional lines of the inner walls of the first and second horns along the central axis of the double-horn body flow guide with gradual curvature are arc lines, and the curvature of the arc lines of the first and second horns first increases and then decreases from the large-mouth end to the small-mouth end of the first and second horns.

[0065] Optionally, in the series flow guide assembly, the central axes of all the dual-flared flow guides with gradually varying curvatures are located on the same straight line. In this embodiment, when the central axes of all the dual-flared flow guides with gradually varying curvatures are located on the same straight line, regardless of whether the sizes of these dual-flared flow guides are the same, under the attraction of the energy source, the cold air can be converged in the series flow guide assembly in the same straight line, thereby further enhancing the convergence effect of the cold air and reducing the degree of attenuation of the connection between the energy source and the cold air.

[0066] Optionally, in the series flow guide assembly, the central axes of at least two of the double-horn flow guides with gradual curvature are not on the same straight line; wherein, along the central axis direction of the double-horn flow guide with gradual curvature, the through holes at the center of all the double-horn flow guides with gradual curvature in the series flow guide assembly at least partially overlap. In this solution, even if the central axes of all the double-horn flow guides with gradual curvature in the series flow guide assembly are not on the same straight line, since the central through holes of these double-horn flow guides with gradual curvature at least partially overlap, that is, the middle channel areas of the double-horn flow guides with gradual curvature at least partially overlap, the orthographic projection of the series flow guide assembly in the direction of its central axis will have a hollow area caused by the overlapping central through holes of these double-horn flow guides with gradual curvature, so that a straight channel is formed inside the series flow guide assembly, so that the cold air can move from the overlapping central through holes of these double-horn flow guides with gradual curvature in sequence under the attraction of the energy source, so that the cold air can pass more smoothly.

[0067] Optionally, in the serial flow guide assembly, all of the dual-flared flow guide members with gradually varying curvatures have the same shape and size. In this embodiment, since all of the dual-flared flow guide members with gradually varying curvatures in the serial flow guide assembly have the same shape and size, that is, all of the dual-flared flow guide members with gradually varying curvatures are identical, each dual-flared flow guide member with gradually varying curvatures has the same effect on guiding cold air. Cold air will not experience sudden changes when passing through the serial flow guide assembly, allowing the cold air to pass through the serial flow guide assembly more smoothly.

[0068] Optionally, there is a spacing between adjacent curvature gradient double-horn body guide pieces, with the spacing between adjacent curvature gradient double-horn body guide pieces being D, and the diameter of the large mouth end of the curvature gradient double-horn body guide piece being φ1; wherein, 0.1φ1≤D≤1.5φ1. In this solution, the curvature gradient double-horn body guide pieces in the series guide assembly are arranged in sequence and spaced apart. By retaining the spacing between adjacent curvature gradient double-horn body guide pieces, the cold air diffuses through the previous stage curvature gradient double-horn body guide piece (the curvature gradient double-horn body guide piece that is closer to the human body in the series guide assembly), and can diffuse out of the overlapping range of the large mouth ends of adjacent curvature gradient double-horn body guide pieces, and diffuse out from the spacing between the two, thereby improving the diffusion effect of the cold air and allowing the cold air to fully disperse, so as to form sufficient negative pressure to attract more cold air into the previous stage curvature gradient double-horn body guide piece;

[0069] Correspondingly, the rear-stage, gradually changing, dual-flared guide (the one closer to the energy source in the series of guide assemblies) has ample space to collect the cold air from the preceding one, allowing it to flow more smoothly into the rear-stage guide, reducing air leakage. This spacing allows the two guides to combine forces, enhancing the guiding effect. Moreover, after a spacing is set between adjacent double-horn body guide pieces with gradual curvature, if D is too small, the cold air will easily accumulate between the two adjacent double-horn body guide pieces with gradual curvature, hindering the flow of cold air; if D is too large, the latter double-horn body guide piece with gradual curvature cannot completely gather the cold air flowing out of the former double-horn body guide piece with gradual curvature, causing the cold air to escape and reducing the stability of the connection between the energy source and the cold air; after many experiments, it was verified that when the spacing between the adjacent double-horn body guide pieces with gradual curvature is controlled at 0.1φ1≤D≤1.5φ1, the guiding effect of the series guide assembly is better.

[0070] Optionally, the central axes of all the double-horn-shaped flow guides with gradual curvature in the series flow guide assembly are on the same straight line, and the large mouth ends of adjacent double-horn-shaped flow guides with gradual curvature fit together. In this solution, all the double-horn-shaped flow guides with gradual curvature in the series flow guide assembly are arranged in sequence front to back, and all the double-horn-shaped flow guides with gradual curvature are the same. At this time, the large mouth edges of two adjacent double-horn-shaped flow guides with gradual curvature fit together, which confines the cold air passing through the series flow guide assembly to the internal channel, preventing it from escaping from between adjacent double-horn-shaped flow guides with gradual curvature, so that the cold air can only move in the direction of the energy source and will not overflow in the middle, so the connection between the cold air and the energy source will not be weakened, thereby improving the stability of the connection between the energy source and the cold air.

[0071] Optionally, in the series flow guide assembly, the number of the double-horn flow guides with gradual curvature is greater than or equal to 3 and less than or equal to 5. In this solution, the more double-horn flow guides with gradual curvature connected in series in the series flow guide assembly, the more stable the connection between the cold air and the energy source, and the larger the volume of the entire series flow guide assembly; if the number of double-horn flow guides with gradual curvature connected in series in the series flow guide assembly is small, the stabilizing effect of the entire series flow guide assembly on the cold air will be insufficient; therefore, the inventor verified from this quantitative direction that when the number of double-horn flow guides with gradual curvature in the series flow guide assembly is 3-5, it is more appropriate, which can not only ensure the stability between the cold air and the energy source, but also avoid the excessive volume of the entire series flow guide assembly.

[0072] Optionally, the series flow guide assembly includes at least a first curvature gradient double-horn flow guide, a second curvature gradient double-horn flow guide, and a third curvature gradient double-horn flow guide, wherein the second curvature gradient double-horn flow guide is arranged between the first curvature gradient double-horn flow guide and the third curvature gradient double-horn flow guide; wherein the size of the first curvature gradient double-horn flow guide and the size of the third curvature gradient double-horn flow guide are both larger than the size of the second curvature gradient double-horn flow guide. In this solution, when the size of the curvature gradient double-horn flow guide is larger, more cold air can be gathered; when the size of the curvature gradient double-horn flow guide is smaller, the cold air can be more concentrated, thereby improving the stability of the connection between the cold air and the energy source; therefore, this solution adopts a larger curvature gradient double-horn flow guide and a smaller curvature gradient double-horn flow guide to form a series flow guide assembly, so that the series flow guide assembly has the effects of both gathering more cold air and concentrating the cold air.

[0073] In the series flow guide assembly, the larger curvature gradient double-horn flow guide is placed on the outside, and the smaller curvature gradient double-horn flow guide is placed on the inside. Since the larger curvature gradient double-horn flow guide is placed on the outside, the larger curvature gradient double-horn flow guide is opposite the human body and the energy source. Therefore, the curvature gradient double-horn flow guide facing the human body can gather cold air over a larger range, and the curvature gradient double-horn flow guide facing the energy source can establish a connection between the cold air and the energy source over a larger range, so that the cold air and the energy source can fully contact each other, thereby making the connection between the two more stable. The smaller curvature gradient double-horn flow guide located inside the series flow guide assembly can make the passing cold air more concentrated and concentrated, making it less likely for the cold air to be interrupted during its movement within the series flow guide assembly.

[0074] Optionally, the series guide assembly is composed of a first curvature gradient double-horn body guide piece, a second curvature gradient double-horn body guide piece, and a third curvature gradient double-horn body guide piece; and the size of the first curvature gradient double-horn body guide piece is equal to the size of the third curvature gradient double-horn body guide piece. In this solution, the series guide assembly is composed of three curvature gradient double-horn body guide pieces connected in series, and the curvature gradient double-horn body guide pieces at both ends are larger in size, and the curvature gradient double-horn body guide piece in the middle is smaller in size, so that the series guide assembly can gather cold air in a larger range, make the connection between the two more stable, and make the cold air less likely to be interrupted during the movement of the series guide assembly, while also reducing the volume of the entire series guide assembly.

[0075] Optionally, the series flow guide assembly further includes a fourth curvature gradient double horn flow guide piece and a fifth curvature gradient double horn flow guide piece, the fourth curvature gradient double horn flow guide piece is located between the first curvature gradient double horn flow guide piece and the second curvature gradient double horn flow guide piece, the fifth curvature gradient double horn flow guide piece is located between the first curvature gradient double horn flow guide piece and the fourth curvature gradient double horn flow guide piece; wherein, the first curvature gradient double horn flow guide piece, the third curvature gradient double horn flow guide piece and the fourth curvature gradient double horn flow guide piece are respectively provided. The sizes of the first curvature gradient double horn body flow guide piece and the fourth curvature gradient double horn body flow guide piece are equal, and the sizes of the second curvature gradient double horn body flow guide piece and the fifth curvature gradient double horn body flow guide piece are equal; the series flow guide component is composed of a first curvature gradient double horn body flow guide piece, a second curvature gradient double horn body flow guide piece, a third curvature gradient double horn body flow guide piece, a fourth curvature gradient double horn body flow guide piece and a fifth curvature gradient double horn body flow guide piece.

[0076] In this solution, the series guide assembly is composed of five double-horn body guide pieces with gradual curvature connected in series, and a double-horn body guide piece with gradual curvature of smaller size is sandwiched between every two double-horn body guide pieces with gradual curvature of larger size, so that the cold air enters the series guide assembly and goes through five processes of dispersion, convergence, dispersion, convergence, and dispersion. After the cold air passes through the convergence and compression of the two double-horn body guide pieces with gradual curvature of smaller size, it will be more stable during the movement; moreover, a double-horn body guide piece with gradual curvature of larger size is sandwiched between the two double-horn body guide pieces with gradual curvature of smaller size, so that after the cold air passes through the double-horn body guide piece with gradual curvature of smaller size, it is fully gathered together again by the double-horn body guide piece with gradual curvature of larger size, thereby reducing the cold air escaping from between the two double-horn body guide pieces with gradual curvature of smaller size.

[0077] Optionally, the smaller dual-flare flow guide with a gradual curvature is a scaled-down version of the larger dual-flare flow guide with a gradual curvature. In this solution, all dual-flare flow guides with a gradual curvature in the series flow guide assembly have the same appearance, differing only in size. This provides greater consistency across the dual-flare flow guides, ensuring smoother flow and improved stability between the different dual-flare flow guides.

[0078] Optionally, when the size of the larger-sized double-flare flow guide piece with a gradual curvature remains unchanged, the larger the diameter of the large-mouth end of the smaller-sized double-flare flow guide piece with a gradual curvature, the larger the distance between the smaller-sized double-flare flow guide piece with a gradual curvature and the adjacent larger-sized double-flare flow guide piece with a gradual curvature. In this solution, since the smaller the size of the curvature gradient double-flare body guide piece, the smaller the diameter of its large mouth end, and the worse its ability to gather cold air, it is placed closer to the adjacent large-sized curvature gradient double-flare body guide piece to fully gather the cold air emitted by the previous level adjacent large-sized curvature gradient double-flare body guide piece; conversely, if the larger the size of the curvature gradient double-flare body guide piece, the larger the diameter of its large mouth end, the better its ability to gather cold air, if it is too close to the adjacent large-sized curvature gradient double-flare body guide piece, it will hinder the dispersion of the cold air coming out of the previous level curvature gradient double-flare body guide piece, so it needs to be placed farther away from the adjacent large-sized curvature gradient double-flare body guide piece.

[0079] Optionally, when the diameter of the large mouth end of the smaller-sized double-flare flow guide with a gradual curvature increases by 1 times, the distance between the smaller-sized double-flare flow guide with a gradual curvature and the adjacent larger-sized double-flare flow guide with a gradual curvature increases by greater than or equal to 1.5 times and less than or equal to 3 times.

[0080] Optionally, the diameter of the through hole at the center of the double-flared flow guide with a gradual curvature (φ0): the diameter of the large mouth end of the double-flared flow guide with a gradual curvature (φ1): the length of the double-flared flow guide with a gradual curvature (L) are equal to 1:7-13:2-8.

[0081] In this solution, since the larger the diameter of the large mouth end of the curvature gradient double-flare body guide piece, the more cold air is gathered, and since the smaller the diameter of the through hole at the center of the curvature gradient double-flare body guide piece, the better the effect of gathering the cold air, if the ratio between the diameter of the large mouth end of the curvature gradient double-flare body guide piece and the diameter of the through hole at the center is too large, the diameter of the through hole at the center of the curvature gradient double-flare body guide piece will be very small relative to the diameter of the large mouth end of the curvature gradient double-flare body guide piece, so that the cold air gathered by the curvature gradient double-flare body guide piece per unit time exceeds the cold air passing through it per unit time, causing the cold air to accumulate at the center of the channel of the curvature gradient double-flare body guide piece. If the ratio between the diameter of the wide-mouth end of a double-flared curvature guide and the diameter of the central through-hole is too small, the diameter of the central through-hole will be close to the diameter of the wide-mouth end of the guide, and the shape of the guide will develop in the direction of a circular tube. This will lead to a decrease in the effect of the guide on cold air, and the guide's ability to guide cold air will be weakened. Similarly, if the ratio of the wide-mouth end diameter to the length of the double-flared curvature guide is too large, cold air will easily accumulate in the center of the channel; if it is too small, the guide's ability to guide cold air will be weakened.

[0082] Optionally, the size ratio of the larger curvature gradient double-flare flow guide piece to the smaller curvature gradient double-flare flow guide piece is between 2-8:1; the spacing (D) between the larger curvature gradient double-flare flow guide piece and the adjacent smaller curvature gradient double-flare flow guide piece is greater than or equal to 0.8 times the large mouth end diameter (φ11) of the smaller curvature gradient double-flare flow guide piece, and less than or equal to 2.5 times the large mouth end diameter (φ11) of the smaller curvature gradient double-flare flow guide piece. In this solution, if the distance between a larger curvature gradient double-flare body guide piece and an adjacent smaller curvature gradient double-flare body guide piece is too small, the cold air will easily accumulate between the two curvature gradient double-flare body guide pieces, hindering the circulation of the cold air; if the distance between a larger curvature gradient double-flare body guide piece and an adjacent smaller curvature gradient double-flare body guide piece is too large, the latter stage curvature gradient double-flare body guide piece cannot completely gather the cold air flowing out of the former stage curvature gradient double-flare body guide piece, causing the cold air to escape and reducing the stability of the connection between the energy source and the cold air; it has been verified that for curvature gradient double-flare body guide pieces of different sizes, connecting them in series so that 0.8φ11≤D≤2.5φ11 can not only avoid the accumulation of cold air, but also make the connection between the energy source and the cold air more stable.

[0083] Optionally, the spacing (D) between a larger curvature gradient double-flare flow guide piece and an adjacent smaller curvature gradient double-flare flow guide piece is greater than or equal to 1.2 times the diameter (φ11) of the large mouth end of the smaller curvature gradient double-flare flow guide piece, and less than or equal to 2 times the diameter (φ11) of the large mouth end of the smaller curvature gradient double-flare flow guide piece.

[0084] The present application also discloses a nested guide assembly, wherein both ends of the nested guide assembly are open and the interior is hollow to form a channel, and the nested guide assembly includes at least two levels of curvature gradient double-horn body guide pieces, the sizes of the curvature gradient double-horn body guide pieces at different levels are different, and the curvature gradient double-horn body guide piece at the lower level is nested in the curvature gradient double-horn body guide piece at the upper level; the channel of the curvature gradient double-horn body guide piece is double-horn shaped, and the curvature gradient double-horn body guide piece includes a first horn and a second horn symmetrically arranged, the first horn includes a large mouth end and a small mouth end, the second horn includes a large mouth end and a small mouth end, and the large mouth of the first horn The diameter of the end is larger than the diameter of the small-mouth end of the first horn, and the diameter of the large-mouth end of the second horn is larger than the diameter of the small-mouth end of the second horn; the small-mouth end of the first horn is connected with the small-mouth end of the second horn to form the double-horn-shaped channel; the section line of the inner wall of the first horn along the central axis of the double-horn body guide member with gradual curvature is an arc, and the arc is concave toward the central axis; in the nested guide assembly, viewed along the central axis of the double-horn body guide member with gradual curvature of the upper level, the through holes of the double-horn body guide member with gradual curvature of the upper level and the double-horn body guide member with gradual curvature of the lower level at the narrowest part of the channel at least partially overlap.

[0085] In this solution, a nested guide assembly is adopted in which multiple levels of curvature gradient double-horn body guide pieces are nested. Since the curvature gradient double-horn body guide piece of the upper level has a larger opening and a wide coverage area, it can gather more cold air; and the curvature gradient double-horn body guide piece of the lower level has a smaller opening, so that the cold air gathered through the opening of the curvature gradient double-horn body guide piece of the upper level enters the small wormhole, and through secondary guidance, it can enhance the attraction of the cold air, allowing the cold air to pass through the nested guide assembly more stably; at the same time, the center of the curvature gradient double-horn body guide piece of the lower level is narrower, which can make the cold air more concentrated. After adopting the nested guide assembly, the attraction formed by at least two layers of guidance brought by the upper-level curvature gradient double-horn guide piece and the lower-level curvature gradient double-horn guide piece is sufficient to allow more concentrated cold air to pass through the central through hole of the lower-level curvature gradient double-horn guide piece, thereby driving the deeper cold air of the human body out into the nested guide assembly, which can better clear the root cause of the cold air and improve the health level of the human body.

[0086] Optionally, the cross-sectional lines of the inner walls of the first and second horns along the central axis of the double-horn body flow guide with gradual curvature are arc lines, and the curvature of the arc lines of the first and second horns first increases and then decreases from the large-mouth end to the small-mouth end of the first and second horns.

[0087] Optionally, in the nested guide assembly, the central axes of all the dual-flared guides with gradually varying curvatures are aligned on the same straight line. In this embodiment, after all the dual-flared guides with gradually varying curvatures are coaxially arranged, the convergence direction of the cold air from the upper-stage dual-flared guide and the lower-stage dual-flared guide tends to be aligned on the same straight line, so that the cold air is guided out along the same straight line, which improves the stability of the cold air guidance and is not easily disturbed by the external environment.

[0088] Optionally, in the nested guide assembly, an air duct is provided between two adjacent levels of the double-horn-shaped guide members with gradually varying curvatures, and the two ends of the air duct are respectively connected to the outside world at both ends of the nested guide assembly. In this solution, since there is an air duct between two adjacent levels of the double-horn-shaped guide members with gradually varying curvatures, the lower level double-horn-shaped guide member with gradually varying curvatures does not block the middle through hole of the upper level double-horn-shaped guide member with gradually varying curvatures, that is, the first horn and the second horn of the upper level double-horn-shaped guide member with gradually varying curvatures are still connected, and the upper level double-horn-shaped guide member with gradually varying curvatures still retains sufficient cold air guiding capability, can attract cold air into its interior, and then guide the cold air into the lower level double-horn-shaped guide member with gradually varying curvatures, thereby enhancing the cold air guiding effect.

[0089] Optionally, there is only one double-horn-shaped guide piece with a gradual curvature at each level, and the center points of all the double-horn-shaped guide pieces with a gradual curvature coincide. In this solution, the direction of convergence of the cold air by the double-horn-shaped guide pieces with a gradual curvature at each level tends to the same center position, making the cold air more concentrated, thereby being able to draw out the cold air at a deeper level. In addition, only one double-horn-shaped guide piece with a gradual curvature at the next level is nested in the middle of the double-horn-shaped guide piece with a gradual curvature at the previous level; the large mouth end of the double-horn-shaped guide piece with a gradual curvature at the next level is closer to the center position of the double-horn-shaped guide piece with a gradual curvature at the previous level, and the arc surface transition between the two adjacent double-horn-shaped guide pieces with a gradual curvature is more natural, so that the process of drawing out the cold air is not easily disturbed.

[0090] Optionally, the nested guide assembly is a two-stage nested guide assembly, consisting of a first double-flared guide member with a gradually varying curvature and a second double-flared guide member with a gradually varying curvature, wherein the first double-flared guide member is nested within the second double-flared guide member. In this embodiment, the nested guide assembly utilizes two layers of nested double-flared guide members with a gradually varying curvature, which is easy to manufacture and relatively low in cost. Furthermore, the entire nested guide assembly is relatively small, making it suitable for dispelling cold air from a specific part of the human body.

[0091] Optionally, the nested guide assembly is a three-stage nested guide assembly, which consists of a third curvature gradient double horn body guide piece, a fourth curvature gradient double horn body guide piece and a fifth curvature gradient double horn body guide piece, the third curvature gradient double horn body guide piece is nested in the fourth curvature gradient double horn body guide piece, and the fourth curvature gradient double horn body guide piece is nested in the fifth curvature gradient double horn body guide piece. In this solution, as the number of levels in the nested guide assembly increases, the more nesting levels there are, so that the size of the outermost layer's double-horn body guide member with a gradual curvature becomes larger, and the size of the innermost layer's double-horn body guide member with a gradual curvature becomes smaller, so that a larger opening area and a smaller central through hole can be obtained at the same time, so that the guiding effect of the nested guide assembly is better; however, as the number of nesting levels increases, the size of the nested guide assembly will increase significantly, affecting actual use; therefore, in order to avoid the size of the guide assembly being too large and to improve the guiding effect of the guide assembly, the nested guide assembly is designed as a three-layer nested structure consisting of a third double-horn body guide member with a gradual curvature, a fourth double-horn body guide member with a gradual curvature, and a fifth double-horn body guide member with a gradual curvature.

[0092] Optionally, the number of the curvature gradient double-flare flow guide members of the next level is at least two, at least two of the curvature gradient double-flare flow guide members of the next level are nested side by side in the curvature gradient double-flare flow guide member of the previous level, and the large mouth ends of the two curvature gradient double-flare flow guide members of the same level are arranged relative to each other. In this solution, since at least two of the curvature gradient double-horn body guide pieces of the next level are nested inside a curvature gradient double-horn body guide piece of the previous level, and there is no gap between the curvature gradient double-horn body guide pieces connected in series, the cold air will be more concentrated and more directed after passing through at least two of the curvature gradient double-horn body guide pieces of the next level connected in series; and since the curvature gradient double-horn body guide piece of the previous level is nested outside the curvature gradient double-horn body guide piece of the series, the cold air will not be retained between the curvature gradient double-horn body guide pieces of the next level connected in series under the guidance of the curvature gradient double-horn body guide piece of the previous level, and the cold air can pass through the nested guide assembly in a more concentrated manner, further improving the stability of the cold air discharge while ensuring that the cold air can smoothly pass through the curvature gradient double-horn body guide piece of the next level.

[0093] Optionally, the nested guide assembly includes a first-stage, gradually changing, double-flared-body guide member and a second-stage, gradually changing, double-flared-body guide member, wherein the number of the first-stage, gradually changing, double-flared-body guide member is one, and the number of the second-stage, gradually changing, double-flared-body guide members is two; the two second-stage, gradually changing, double-flared-body guide members are nested side by side within the first-stage, gradually changing, double-flared-body guide member. In this embodiment, due to the excessive number of next-stage, gradually changing, double-flared-body guide members nested within the previous-stage, gradually changing, double-flared-body guide member, the next-stage, gradually changing, double-flared-body guide member may protrude excessively from the center of the previous-stage, gradually changing, double-flared-body guide member. That is, the large end of the next-stage, gradually changing, double-flared-body guide member located at the edge may be closer to the large end of the previous-stage, gradually changing, double-flared-body guide member. As a result, after the cold air is gathered by the large end of the previous-stage, gradually changing, double-flared-body guide member, it may be difficult to guide it into the next-stage, gradually changing, double-flared-body guide member.

[0094] Optionally, the nested guide assembly includes a first-stage curvature gradient double-flare guide piece, a second-stage curvature gradient double-flare guide piece and a third-stage curvature gradient double-flare guide piece, the number of the first-stage curvature gradient double-flare guide piece is one, the number of the second-stage curvature gradient double-flare guide piece is two, and the number of the third-stage curvature gradient double-flare guide piece is four; two of the third-stage curvature gradient double-flare guide pieces are nested side by side in one of the second-stage curvature gradient double-flare guide pieces, with their large mouth ends facing each other; two of the second-stage curvature gradient double-flare guide pieces are nested side by side in the first-stage curvature gradient double-flare guide piece, with their large mouth ends facing each other. In this solution, the more nested layers there are inside the nested guide component, the better the guiding effect will be, but it will lead to a larger volume of the nested guide component and a higher cost. Considering all factors, it would be more appropriate to adopt a three-layer nested design of a first-level curvature gradient double-horn guide component, a second-level curvature gradient double-horn guide component and a third-level curvature gradient double-horn guide component.

[0095] Optionally, the next-stage dual-flare flow guide with a gradual curvature is a scaled-down version of the previous-stage dual-flare flow guide with a gradual curvature. In this solution, the dual-flare flow guides with a gradual curvature at each stage have the same shape and good consistency, and the inner wall curved surfaces of adjacent dual-flare flow guides have a natural transition, making the cold air guiding process smoother.

[0096] Optionally, the distance between the wide-mouth end of the gradient curvature double-flared body guide member of the next stage and the corresponding wide-mouth end of the gradient curvature double-flared body guide member of the previous stage exceeds one-quarter the length of the gradient curvature double-flared body guide member of the previous stage. In this solution, after the gradient curvature double-flared body guide members of two adjacent stages are nested, the end surface of the wide-mouth end of the gradient curvature double-flared body guide member of the next stage exceeds half the length of a single flare in the gradient curvature double-flared body guide member of the previous stage, thereby preventing the end of the gradient curvature double-flared body guide member of the next stage from protruding too much, which would make it difficult for the cold air gathered by the gradient curvature double-flared body guide member of the previous stage to be easily introduced into the internal channel of the gradient curvature double-flared body guide member of the next stage.

[0097] Optionally, the edge of the large opening of the lower-stage double-flared flow guide with a gradual curvature is fixed to the inner wall of the upper-stage double-flared flow guide with a gradual curvature via a fixing structure. In this solution, the lower-stage double-flared flow guide with a gradual curvature is fixed nearby, minimizing the space occupied by the fixing structure and reducing the obstruction of the cold air guide path by the fixing structure.

[0098] The present application also discloses a deflector, the two ends of which are open and the interior is hollow to form a channel, the deflector includes at least one nested deflector assembly and at least one independent curvature gradient double-horn deflector, one end of the curvature gradient double-horn deflector and one end of the nested deflector assembly are arranged relative to each other; or, the deflector includes at least two nested deflector assemblies, and one end of adjacent nested deflector assemblies are arranged relative to each other; the nested deflector assembly includes at least two levels of curvature gradient double-horn deflectors, and the sizes of curvature gradient double-horn deflectors at different levels are different, and the curvature gradient double-horn deflector of the lower level is nested in the curvature gradient double-horn deflector of the upper level; the channel of the curvature gradient double-horn deflector is double-horn shaped, and the curvature gradient double-horn deflector includes symmetrically arranged The first horn and the second horn, the first horn includes a large mouth end and a small mouth end, the second horn includes a large mouth end and a small mouth end, the diameter of the large mouth end of the first horn is larger than the diameter of the small mouth end of the first horn, and the diameter of the large mouth end of the second horn is larger than the diameter of the small mouth end of the second horn; the small mouth end of the first horn is connected with the small mouth end of the second horn to form the double-horn-shaped channel; the section line of the inner wall of the first horn along the central axis of the double-horn body guide member with gradual curvature is an arc, and the arc is concave toward the central axis; in the nested guide assembly, viewed along the central axis of the double-horn body guide member with gradual curvature, the through holes of the double-horn body guide member with gradual curvature at the upper level and the double-horn body guide member with gradual curvature at the lower level at the narrowest part of the channel at least partially overlap.

[0099] In this solution, by placing two or more nested guide components in parallel, or placing nested guide components and curvature gradient double-horn guide pieces in parallel, the cold air can be converged twice or more, and the tendency of the cold air to move toward the energy source along the axis direction is stronger, making it less likely for the cold air to attenuate during the movement. Compared with a single nested guide component, the cold air after the series design in this solution is converged multiple times, and the final amount of cold air that is scattered is less, the connection between the cold air and the energy source is stronger, and the stability is better. During the movement process, the secondary convergence of the latter-stage nested guide component or curvature gradient double-horn guide piece has a stabilizing effect on the former-stage nested guide component or curvature gradient double-horn guide piece, and the former-stage nested guide component or curvature gradient double-horn guide piece is less affected by changes in the external environment and is more stable during the movement. In summary, the use of a deflector can enhance the guiding effect of the cold air, while stabilizing the connection between the cold air and the energy source during the movement, and improving the effect of removing the cold air.

[0100] Optionally, the cross-sectional lines of the inner walls of the first and second horns along the central axis of the double-horn body flow guide with gradual curvature are arc lines, and the curvature of the arc lines of the first and second horns first increases and then decreases from the large-mouth end to the small-mouth end of the first and second horns.

[0101] Optionally, the deflector is composed of at least two nested deflector components, each of which has the same size. In this embodiment, since the nested deflector components have the same size, each nested deflector component has the same guiding and converging effect on the cold air. The cold air will not experience sudden changes when passing through the deflector, allowing the cold air to pass through the deflector more smoothly.

[0102] Optionally, the deflector includes two nested deflector components and one curvature gradient double-horn deflector, and the curvature gradient double-horn deflector is located between the two nested deflector components; wherein the size of the curvature gradient double-horn deflector is smaller than the size of the outermost curvature gradient double-horn deflector in the nested deflector components. In this solution, when the size of the outermost curvature gradient double-horn deflector in the nested deflector components is larger, more cold air can be gathered; when the size of the curvature gradient double-horn deflector is smaller, the cold air can be more concentrated, thereby improving the stability of the connection between the cold air and the energy source; therefore, this solution adopts a combination of a larger-sized nested deflector component and a smaller-sized curvature gradient double-horn deflector to form a deflector, so that the deflector has the effects of both gathering more cold air and concentrating the cold air.

[0103] Optionally, the diversion module is made of a transparent material. In this solution, the inventors discovered that non-transparent materials have a stronger attraction to cold air, causing significant retention of cold air as it passes through the diversion element, affecting the smooth passage of subsequent cold air. Over time, the diversion capacity decreases. Using transparent materials, however, reduces cold air retention.

[0104] The present application also discloses a method for using the cold-dispelling device, which is used for the cold-dispelling device as described above, comprising the steps of:

[0105] Align one end of the diversion module with the user to be de-chilled, and align the other end with the energy source on the energy source fixing device, so that the distance between the diversion module and the user to be de-chilled is a first alignment distance, and the distance between the diversion module and the energy source is a second alignment distance; and

[0106] After waiting for a first preset time, the control module drives the moving component to drive the energy source and the diversion module to move a first preset distance away from the user to be cleared of cold air.

[0107] In this solution, the control module controls the movement of the energy source, replacing manual labor. During movement, the device precisely follows the programmed process, operating stably and reliably. During movement, the connection between the cold air and the energy source is not easily disconnected, allowing the cold air to be continuously drawn out from the user, effectively eliminating the cold. This product eliminates the need for manual operation, meaning it doesn't rely on professionals, and can be used by ordinary users.

[0108] Optionally, the moving component drives the energy source and the diversion module to move a first preset distance away from the user to be cleared of cold, and then stays for a second preset time.

[0109] Optionally, the first preset time is 10-300s, the first preset distance is 50-200cm, and the second preset time is 10-300s; in the process of the moving component driving the energy source and the diversion module to move the first preset distance away from the user to be rid of cold air, the moving speed of the energy source and the diversion module is consistent and uniform, and the moving speed is between 2mm / s-5mm / s.

[0110] Optionally, the first alignment distance is between 5-30 cm, and the second alignment distance is between 5-30 cm.

[0111] Optionally, the energy source is an moxa product, and after staying for a second preset time, the moxa product is removed from the moving component.

[0112] Optionally, the energy source is essential oil, and the essential oil is set in an essential oil bottle with a bottle cap. After the control module waits for a first preset time, before the control module drives the moving component to drive the energy source and the diversion module to move a first preset distance away from the user to be dispelled cold, the bottle cap of the essential oil bottle is opened and the first preset time is waited; after the control module drives the moving component to drive the energy source and the diversion module to move a first preset distance away from the user to be dispelled cold and stay for a second preset time, the bottle cap of the essential oil bottle is closed.

[0113] Optionally, during use of the cold-removing device, the energy source and the diversion module only move in a direction away from the user to be cold-removed, and do not return.

[0114] In this solution, after an energy source such as moxa sticks is aimed at the user to be cured of cold at close range, a more stable connection between the energy source and the cold air can be established by waiting for a first preset time, and then a diversion module is added to further improve the stability of the connection between the energy source and the cold air of the user to be cured of cold. The diversion module and the energy source are then moved away from the user to be cured of cold. During the movement, the connection between the cold air and the energy source is relatively difficult to disconnect, which is more objective and easier to operate. The cold air can be continuously drawn out of the body, and the efficiency of drawing out cold air is significantly better than the existing sparrow pecking moxibustion.

For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0174] The present application is described in detail below with reference to the accompanying drawings and optional embodiments.

[0175] As shown in Figure 1, the present application provides a device 10 for dispelling cold air, which includes a mobile component 100, an energy source fixing structure 200, a diversion module 300 and a control module 400. The energy source fixing structure 200 is arranged on the mobile component 100 for fixing the energy source 600; the diversion module 300 is arranged on the mobile component 100, and both ends of the diversion module 300 are open and the interior is hollow to form a channel, one end of the channel faces the energy source 600, and the other end of the channel faces the user to be dispelled cold air; the control module 400 is connected to the mobile component 100, and is used to drive the mobile component 100 to drive the energy source fixing structure 200 and the diversion module 300 to move in a direction away from the user to be dispelled cold air.

[0176] The inventors have found that although people are aware of sparrow pecking moxibustion, their understanding of its principles is not sufficient. The inherent view is that the moxa is first brought close to the human body part, and then quickly pulled out in a similar way to pulling out a plug, leading the cold air to escape, pulling out a small amount at a time, and thus requiring multiple times of releasing the cold air. Using the sparrow pecking moxibustion technique, there is no conscious pause when the energy source 600 approaches the user to be relieved of the cold. The connection is mainly established by the moxa stick as it approaches the user to be relieved of the cold. The sparrow pecking moxibustion is also relatively fast when approaching, and there is no conscious pause, resulting in an unstable connection. Therefore, if the speed is slow during the removal process, it is easy to break. On the contrary, only by pulling out quickly can a certain amount of cold air be released before the connection is broken. As a result, the cold air brought out each time the plug is pulled out is quite limited, and it must be repeated many times to achieve a certain effect. Moreover, as the superficial coldness at the moxibustion site is pulled out, it is difficult for the moxa stick to establish connection with the deeper coldness. As the number of back and forth movements increases, the coldness brought out each time gradually becomes less. After a certain number of times of pulling out the moxa stick, even if you continue to pull out the moxa stick, it will have no effect.

[0177] In this solution, after an energy source such as moxa sticks is aligned closely with the user to be cured of cold, a more stable connection between the energy source and the cold air can be established by waiting for a first preset time. A diversion module is then added to further improve the stability of the connection between the energy source and the cold air of the user to be cured of cold. The diversion module 300 and the energy source are then moved together away from the user to be cured of cold, so that in the process of moving the energy source 600 and the diversion module 300 in a direction away from the user to be cured of cold, the connection between the cold air and the energy source 600 is relatively difficult to break. Through a single movement process, that is, during the use of the cold-dispelling device 10, the energy source fixing structure 200 and the diversion module 300 only move in a direction away from the user to be cured of cold and do not return. Neither the energy source 600 nor the diversion module 300 moves in the direction of the user to be cured of cold, and the cold air can be continuously drawn out of the body. The efficiency of drawing out the cold air is significantly better than that of existing sparrow pecking moxibustion. It is also more objective and easier to operate.

[0178] The diversion module 300 of the embodiment of the present application includes at least a first speaker 311 and a second speaker 312 to form the channel. The first speaker 311 includes a large mouth end 310a and a small mouth end 310b, and the second speaker 312 includes a large mouth end 310a and a small mouth end 310b. The diameter of the large mouth end 310a of the first speaker 311 is larger than the diameter of the small mouth end of the first speaker 310b, and the diameter of the large mouth end 310a of the second speaker 312 is larger than the diameter of the small mouth end 310b of the second speaker 312. When the diversion module 300 is in use, the large mouth end 310a of the first speaker 311 faces the energy source fixing structure 200, and the large mouth end 310a of the second speaker 312 faces the user to be rid of cold air, and it is best to leave a gap between the large mouth end 310a of the first speaker 311 and the energy source 600 to better guide the cold air.

[0179] In this way, the cold air from the human body gathers in the channel of the first speaker 311, is guided through the channel of the second speaker 312, and diffuses toward the energy source 600; this diffusion process will further amplify the guiding effect of the cold air, attracting more cold air to pass through the first speaker 311, that is, the cold air will be accelerated after passing through the first speaker 311, and then drive more cold air to enter the first speaker 311 at an accelerated speed, greatly improving the efficiency of drawing out the cold air. During the verification process, the inventors also found that after adopting the double-horn channel structure, users generally reported that it can draw out deeper cold air. According to the inventors' analysis, the cold air inside the human body is interconnected. When the attraction is strong enough, it can drive the deep cold air to move to the surface, and finally be drawn out of the body into the channel of the first speaker 311. Therefore, after adding the channel of the second speaker 312, the guiding effect of the diversion module 300 on the cold air is significantly improved, which is enough to draw out the cold air from deeper levels of the human body.

[0180] Secondly, the first speaker 311 and the second speaker 312 are arranged axially symmetrically. With this symmetrical dual-speaker structure, the second speaker 312 and the first speaker 311 have matching cold air gathering capabilities. The cold air extraction process is consistent during movement, making the connection between the cold air and the energy source 600 more stable and less likely to be interrupted. If these are inconsistent, two situations may arise: If the guiding capacity of the second speaker 312's channel exceeds that of the first speaker 311's channel, the first speaker 311's channel cannot keep up. During movement, the cold air cannot be effectively introduced into the first speaker 311-shaped channel, easily severing the connection between the cold air and the energy source 600. Alternatively, if the guiding capacity of the second speaker 312's channel is lower than that of the first speaker 311's channel, the cold air is easily trapped at the small opening 310b, preventing it from smoothly passing through the diversion module 300. This reduces the guiding effect, but also increases the risk of severing the connection between the cold air and the energy source 600 during movement.

[0181] As an embodiment, the diversion module 300 has an axisymmetric structure with the channel extending in the direction of its central axis. The inner walls of the first and second speakers 311, 312 are arc-shaped along the cross-sectional line on the central axis of the diversion module 300, and the arc is concave toward the central axis of the diversion module 300. The inner walls of the first and second speakers 311, 312 have concave arc surfaces. After cold air enters the large opening 310a of the first speaker 311 from the human body, it is gradually guided by the arc surface without any sudden changes. Simultaneously, under the guidance of the arc surface, the cold air naturally transitions from the small opening 310b of the first speaker 311 to the second speaker 312, and gradually diffuses toward the energy source under the guidance of the arc surface of the second speaker 312. This results in a smoother cold air guidance process, allowing the cold air to establish a more stable connection with the energy source.

[0182] The inner walls of the first horn 311 and the second horn 312 of the diversion module 300 are arcs along the cross-sectional line on the central axis. From the large mouth end 310a of the first horn 311 and the second horn 312 to the small mouth end 310b, the curvature of the arc of the first horn 311 and the second horn 312 gradually increases or first increases and then decreases.

[0183] As an embodiment, the cross-sectional lines of the inner walls of the first horn 311 and the second horn 312 along the central axis of the guide module 300 are arcs, and the curvature of the arcs of the first horn 311 and the second horn 312 increases from the large mouth end 310a to the small mouth end 310b of the first horn 311 and the second horn 312.

[0184] Specifically, the cross-sectional line of the inner wall of the first horn 311 and the second horn 312 along the central axis of the diversion module 300 is an arc s, which is concave toward the central axis, and the curvature of the arc increases from the large-mouth end 310a of the first horn 311 and the second horn 312 toward the corresponding small-mouth end 310b; the arc extends toward the large-mouth end 310a, and the curvature tends to zero; the tangent of the arc corresponding to the endpoint of the large-mouth end 310a of the first horn 311 tends to be perpendicular to the central axis; the arc approaches the central axis toward the small-mouth end 310b of the first horn 311, but does not intersect, that is, the diameter of the narrowest part in the middle of the diversion module 300 tends to be infinitesimal.

[0185] The cross-sectional lines of the first speaker 311 and the second speaker 312 along the central axis are concave arcs; after the cold air enters the diversion module 300 from the large mouth end 310a of the first speaker 311, it will be accelerated and introduced into the first speaker 311; it will pass through the small mouth end 310b of the first speaker 311 at an accelerated speed to avoid the cold air being blocked at the small mouth end 310b of the first speaker 311; conversely, after the cold air enters the second speaker 312, as the curvature of the second speaker 312 from the small mouth end 310b to the large mouth end 310a gradually increases, the cold air will be further accelerated after passing through the small mouth end 310b of the first speaker 311, thereby driving more cold air into the first speaker 311, thereby enhancing the diversion module 300's ability to guide cold air. After the cold air enters the second speaker 312, it is guided by the inner wall of the second speaker 312, and its acceleration gradually slows from the small opening 310b to the large opening 310a of the second speaker 312. This prevents any interruption in the connection between the cold air and the energy source 600, thereby enhancing the stability of the connection between the cold air and the energy source 600. Therefore, the use of the diversion module 300 not only stabilizes the connection between the energy source 600 and the cold air, but also further enhances the cold air guiding capability of the diversion module 300, resulting in a better cold air guiding effect than a diversion module 300 with a fixed arc curvature.

[0186] It should be noted that the cold-dispelling device 10 in the embodiment of the present application may not be provided with the energy source 600 when it is manufactured, sold, offered for sale, or imported. The energy source 600 may be sold separately and then added when in use, and the energy source 600 may be mounted on the energy source fixing structure 200. In the embodiment of the present application, the energy source 600 may be a substance rich in yang energy. In addition to moxa sticks and other moxa products, one or more light sources such as essential oils 620 or infrared / LEDs may also be used.

[0187] The moving component 100 can move on a certain plane or track, which can be achieved through wheels, pull ropes, tracks, sliders, etc. Under the control of the control module 400, it can drive the energy source fixed structure 200 and the diversion module 300 to move.

[0188] The control module 400 may have a built-in timer and a motor, and may start timing after starting the device. After the first preset time has elapsed, the mobile component 100 is driven by the motor to move. The timer may be a mechanical timer or an electronic timer. In this solution, the control module 400 controls the mobile component 100 to drive the energy source 600 and the diversion module 300 to move, replacing manual labor. During the movement, the mobile component 100 may run precisely according to the set program, and the operation process is stable and reliable. In the process of moving away from the user to be cleared of cold, it is not easy to cause the connection between the cold air and the energy source 600 to be disconnected, and the cold air of the user to be cleared of cold can be continuously drawn out, thereby achieving the effect of clearing the cold. This product no longer requires manual operation, that is, it does not need to rely on professionals, and ordinary users can use it by themselves.

[0189] In this embodiment of the present application, after waiting for a first preset time, the control module 400 drives the moving assembly 100 to move the energy source fixing structure 200 and the diversion module 300 a first preset distance away from the user to be dispelled cold. The first preset time can be set to 10-300 seconds, and the first preset distance can be set to 50-200 cm.

[0190] In this embodiment of the present application, after the control module 400 drives the mobile assembly 100 to move the energy source fixed structure 200 and the diversion module 300 away from the user to be de-cold-expelled by a first preset distance, it further controls the mobile assembly 100 to remain for a second preset time. The second preset time can be set to 10-300 seconds. To further reduce user waiting time, the first preset time and / or the second preset time can be further reduced to 10-60 seconds.

[0191] Moreover, the control module 400 drives the moving component 100 to drive the energy source fixing structure 200 and the diversion module 300 to move a first preset distance at a uniform speed of 2-5 mm / s in a direction away from the user to be relieved of cold.

[0192] The following further describes the present cold-repelling device using various diversion modules as specific embodiments.

[0193] Example 1: Curved double-horn flow guide

[0194] Figure 2 is a flow guide module provided by the first embodiment of the present application. As shown in Figure 2, the flow guide module 300 is a curved double-horn flow guide member 310. The channel of the curved double-horn flow guide member 310 is double-horn-shaped. The double-horn flow guide member includes a first horn 311 and a second horn 312. The first horn 311 includes a large mouth end 310a and a small mouth end 310b. The second horn 312 includes a large mouth end 310a and a small mouth end 310b. The diameter of the large mouth end 310a of the first horn 311 is larger than the diameter of the small mouth end 310b of the first horn 311. The diameter of the large mouth end 310a of the second horn 312 is larger than the diameter of the small mouth end 310b of the second horn 312. The small mouth end 310b of the first horn 311 is connected to the small mouth end 310b of the second horn 312 to form the double-horn-shaped channel.

[0195] As an embodiment, as shown in FIG3 , the arc S of the inner wall of the channel of the cross-section of the double-horn flow guide 315 with a gradual curvature along the central axis, the tangent of the arc corresponding to the endpoint of the large-mouth end of the first horn is perpendicular or tends to be perpendicular to the central axis, and the tangent of the arc corresponding to the endpoint of the large-mouth end of the second horn is perpendicular or tends to be perpendicular to the central axis. In other words, the angle α1 between the tangent of the arc S at the endpoint of the large-mouth end 310a and the perpendicular to the central axis tends to or is infinitely close to 0 degrees. That is, the large-mouth end of the first horn or the second horn tends to be close to the plane perpendicular to the central axis. In this way, from the perspective of the effect of guiding the cold air, the large-mouth end can cover the cold air emitted from the human body as much as possible, and the guiding effect is better.

[0196] The tangent of the arc S at the end point of the small mouth 310b is also parallel to the central axis, or in other words, the angle α2 with the central axis is infinitely close to 0 degrees. The cross-sectional line of the inner wall of the second horn 312 is the same as that of the first horn 311 and will not be repeated here.

[0197] If the angle of the opening of the large mouth end 310a of the double-horn body flow guide 315 with a gradual curvature is too narrow, that is, the cross-sectional line of the double-horn body flow guide 315 with a gradual curvature along the central axis corresponds to the tangent of the large mouth end 310a, and the angle with the central axis is too small, the cold air will not easily gather to the inside of the first horn 311, and the effect of gathering the cold air will be reduced; but if the angle is too large, exceeding 90°, the large mouth end 310a of the double-horn body flow guide 315 with a gradual curvature will produce a flange backward, the cold air will leak out, and the ability to gather the cold air will also decrease, so the curvature of the cross-sectional line of the double-horn body flow guide 315 at the large mouth end 310a tends to zero, and the tangent at the end point tends to be infinitely perpendicular to the central axis, which can better guide the air. On the other hand, the arc of the cross section of the first speaker 311 approaches the central axis toward the small end 310b of the first speaker 311, but does not intersect with it. Similarly, the arc of the cross section of the second speaker 312 approaches the central axis toward the small end 310b of the second speaker 312, but does not intersect with it. That is, the diameters of the small ends 310b of the first and second speakers 311, 312 tend to be infinitesimal. Under the premise that the extension direction of the two large ends 310a of the gradually curvature double-horn body flow guide 315 tends to be infinitesimal, if the diameters of the small ends 310b of the first and second speakers 311, 312 (i.e., the narrowest part of the channel of the gradually curvature double-horn body flow guide 315) can be infinitesimal, the cold air will flow more smoothly within the flow guide, allowing the cold air to be guided more smoothly and more concentratedly, and the cold air will be more effectively drawn out.

[0198] Furthermore, the use of the gradually varying curvature dual-flared flow guide 315 eliminates the need for the energy source 600 to be directly aligned with the wide-mouthed end 310a of the first horn 311. Even if the energy source 600 is positioned a certain distance from the wide-mouthed end 310a coverage area of ​​the first horn 311 (i.e., the projection of the wide-mouthed end 310a of the first horn 311 along its central axis), the cold air can still establish contact with the energy source 600. Therefore, the gradually varying curvature dual-flared flow guide 315 can better stabilize the connection between the energy source 600 and the cold air, ensuring therapeutic efficacy.

[0199] It is understood that the tendency of the tangent lines of the large openings 310a of the first and second horns 311, 312 to be perpendicular to the central axis, and the tendency of the diameters of the small openings 310b of the first and second horns 311, 312 to be infinitely small, are the goals pursued by the dual-horn flow guide 315 with a gradual curvature. This product can be continuously improved with the advancement of existing technology. Therefore, as long as the curvature of the arcs of the first and second horns 311, 312 follows a pattern of increasing curvature from the large openings 310a to the corresponding small openings 310b, they are within the scope of protection of this application.

[0200] Referring to Figure 4, the diameter of the large end 310a at both ends of the double-flared body flow guide 315 with gradual curvature tends to be infinitely large, and the diameter of the narrowest part in the middle is infinitely small, which is the direction pursued by the concept of the present invention. In practical applications, the double-flared body flow guide 315 with gradual curvature has clear dimensions. Here, three size ranges of the double-flared body flow guide 315 with gradual curvature are given: large, medium and small.

[0201] The large-sized curvature gradient double-horn body flow guide 315 has a diameter R1 of the large mouth end 310a of the first horn 311 and the large mouth end 310a of the second horn 312 of 200mm-400mm, and a corresponding diameter R2 of the small mouth end 310b of 20mm-40mm. The distance L1 between the large mouth end 310a of the first horn 311 and the large mouth end 310a of the second horn 312 is 100mm-220mm.

[0202] The medium-sized curvature gradient double-horn body flow guide 315 has a diameter R1 of the large mouth end 310a of the first horn 311 and the large mouth end 310a of the second horn 312 of 100mm-200mm, and a corresponding diameter R2 of the small mouth end 310b of 10mm-20mm. The distance L1 between the large mouth end 310a of the first horn 311 and the large mouth end 310a of the second horn 312 is 50mm-110mm.

[0203] The small-sized curvature gradient double-horn body flow guide 315 has a diameter R1 of the large mouth end 310a of the first horn 311 and a diameter R2 of the large mouth end 310a of the second horn 312 of 10mm-100mm, and a corresponding diameter R2 of the small mouth end 310b of 1mm-10mm. The distance L1 between the large mouth end 310a of the first horn 311 and the large mouth end 310a of the second horn 312 is 5mm-50mm.

[0204] It has been verified that with the existing technological level, the large-sized double-horn-body flow guide 315 with a gradual curvature has a stronger ability to gather cold air; while the small-sized double-horn-body flow guide 315 with a gradual curvature has a stronger ability to guide cold air. Different sizes of double-horn-body flow guide 315 with a gradual curvature can be selected according to different application scenarios.

[0205] As shown in Figure 5, as another embodiment, the arc line S of the cross section of the first horn 311 and the second horn 312 of the double-horn body guide member 315 with gradual curvature along the central axis X, and the tangent lines corresponding to the endpoints of the large mouth ends 310a of the first horn 311 and the second horn 312 tend to be perpendicular to the central axis X.

[0206] Furthermore, the arc S approaches the central axis X in the direction of the small-mouth end 310b of the corresponding first speaker 311 and the second speaker 312; the curvature approaches zero; the diameter of the small-mouth end 310b approaches the preset diameter R, which is not equal to zero, and the recommended range of R is 1-40 mm.

[0207] In the aforementioned embodiment, the extension direction of the large openings 310a at both ends of the gradually changing curvature dual-flared flow guide 315 tends to infinity, while the diameter of the narrowest point in the middle is infinitely small. This is the direction pursued by the present invention. Furthermore, the wall thickness of the gradually changing curvature dual-flared flow guide 315 is minimized, and the difference in wall thickness at different locations of the gradually changing curvature dual-flared flow guide 315 is minimized. Under current technology, it is relatively easy to enlarge the large openings 310a. However, enlarging the large openings 310a increases the volume and weight of the product. While maintaining the thinnest wall thickness, the diameter of the narrowest point in the middle of the gradually changing curvature dual-flared flow guide 315 must be sufficiently large to ensure structural stability. Otherwise, under the influence of the product's gravity, the gradually changing curvature dual-flared flow guide 315 will break in the middle. Therefore, when the small opening 310b has a predetermined diameter, the arcs of the first and second horns 311, 312 tend to be parallel to the central axis toward the small opening 310b, causing the narrowest point in the center of the gradually changing curvature dual horn body to continuously approach the predetermined diameter, while the distance from the central axis also decreases. This also creates a tendency for cold air to converge toward the central axis when passing through the narrowest point in the center of the gradually changing curvature dual horn body guide 315, thereby improving the cold air guiding capability.

[0208] The curvature variation trend of the dual-horn air guide member with gradually varying curvature may not satisfy the rule of increasing from the large-mouth end 310a of the first horn 311 and the second horn 312 to the corresponding small-mouth end 310b.

[0209] As another embodiment, as shown in Figure 6, the cross-sectional line of the inner wall of the first speaker 311 and the second speaker 312 along the central axis of the curvature gradient double speaker body guide member 315 is an arc s. From the large mouth end to the small mouth end of the first speaker 311 and the second speaker 312, the curvature of the arc of the first speaker 311 and the second speaker 312 first increases and then decreases, that is, the curvature of the s3 arc area is the largest, and is simultaneously greater than the curvature of the s1 arc area and the curvature of the s2 arc area.

[0210] The arc line S of the first horn 311 and the second horn 312 of the double-horn flow guide 315 with a gradual curvature, corresponding to the end portion of the large opening 310a, tends to be perpendicular to the central axis X. Of course, the arc line S may not be perpendicular to the central axis, and may be at a certain angle (e.g., it may be an acute 60° angle toward the interior of the flow guide and with the central axis), but the effect may not be as good as when it tends to be perpendicular.

[0211] The arc includes a first arc segment S1, a second arc segment S2, and a third arc segment S3. The leading end of the first arc segment S1 corresponds to the large opening 310a of the gradually changing curvature dual-flared flow guide 315, while the trailing end of the second arc segment S2 corresponds to the small opening 310b of the gradually changing curvature dual-flared flow guide 315. The trailing end of the first arc segment S1 and the leading end of the second arc segment S2 are connected to both ends of the third arc segment S3. The curvature of the first arc segment S1 increases from its leading end to its trailing end. The curvature of the second arc segment S2 decreases from its leading end to its trailing end, with the trailing end approaching the central axis of the gradually changing curvature dual-flared flow guide 315. In other words, the diameter R of the arc S at its narrowest point approaches zero. The curvature of the third arc segment S3 is greater than the curvature of the trailing end of the first arc segment S1 and the curvature of the leading end of the second arc segment S2.

[0212] Alternatively, it can also be understood as: the arc is divided into two parts, the first arc segment S1 and the second arc segment S2, the tail end of the first arc segment S1 is connected to the head end of the second arc segment S2, and the curvature of the first arc segment S1 increases from its head end to its tail end; the curvature of the second arc segment S2 decreases from its head end to its tail end, so as to further improve the guiding effect of the diversion module and improve the stability when the cold air establishes connection with the energy source.

[0213] In the aforementioned embodiment, the arc S of the gradually curving dual-horn flow guide 315 first increases in curvature and then decreases in curvature from the large end 310a to the small end 310b. Based on existing materials and processes, the resulting gradually curving dual-horn flow guide 315 would be very thin in the middle, resulting in low structural strength and prone to breakage. Therefore, the first arc segment S1 has a gradually increasing curvature from its leading end to its trailing end. This ensures that the cold air is accelerated into the flow guide after entering the second horn 312. After passing through the first horn 311, it is then directed back through the second horn 312, allowing the cold air to establish a stable connection with the energy source 600. This ensures both the efficiency of the cold air guidance and the stability of the cold air extraction process. On this basis, the curvature of the second arc segment S2 can be adjusted according to the specific product. For example, when the first arc segment S1 is relatively steep, the area of ​​the second arc segment S2 can be increased gradually, and the curved surface area in the middle area of ​​the double-horn body guide member 315 with a gradual curvature is smooth, thereby enhancing the structural strength; when the first arc segment S1 is relatively flat, the curvature change of the second arc segment S2 can be consistent with that of the first arc segment S1, and the structural strength of the product can also be guaranteed. At this time, it is the same as the double-horn body guide member 315 with a gradual curvature in the aforementioned embodiment.

[0214] As shown in FIG. 7 , in another embodiment, the tangent of the arc S of the first horn 311 and the second horn 312 of the double-horn flow guide 315 with gradual curvature corresponding to the large-mouth end 310 a is perpendicular to the central axis.

[0215] Furthermore, the tangent of the arc s corresponding to the small end 310b is parallel to the central axis X. The diameter of the small end 310b can be flexibly set as needed, for example, between 1mm and 40mm. The small ends 310b of the first and second horns 311 and 312 form a smooth transition. From the large end 310a to the small end 310b, the angle between the tangent at any point on the arc and the central axis gradually decreases from 90° to 0°. The channel diameter at the small end 310b is smaller than the channel diameter at any other point on the gradually curved dual-horn flow guide 315.

[0216] The above-mentioned double-flared flow guide 315 with a gradual curvature has a large mouth 310a that tends to be perpendicular to the central axis, and its diameter tends to be infinite; the diameter at the narrowest point in the middle tends to 0. This type of flow guide can be fitted with a curve that meets the requirements during the design stage, but is limited by the existing processing level and processing cost. In order to make the above-mentioned double-flared flow guide 315 with a gradual curvature, the cost is very high and it cannot be promoted on a large scale. To reduce processing costs, this alternative embodiment clearly defines the boundaries between the large-mouthed end 310a and the small-mouthed end 310b of the gradually changing curvature dual-flared flow guide 315. In terms of the effectiveness of guiding cold air, the large-mouthed end 310a can essentially contain the cold air emitted from the human body, reducing its leakage; while the small-mouthed end 310b is parallel to the central axis, allowing the cold air to be directed in a nearly horizontal direction. This not only prevents cold air from accumulating at the small-mouthed end 310b but also reduces its dispersion, allowing the cold air to be directed toward the energy source 600 in a relatively concentrated manner. This provides a better cold air guidance effect, making it a more ideal alternative. Verification shows that the gradually changing curvature dual-flared flow guide 315 is still more effective in guiding cold air than the curved dual-flared flow guide 310 with a fixed arc curvature, and the cold air guidance effect is still relatively ideal.

[0217] In the embodiment of the present application, the small-mouth end 310b of the first speaker 311 is directly connected to the small-mouth end 310b of the second speaker 312, with a smooth transition at the connection, without abrupt changes or sharp angles. Alternatively, as shown in FIG8 , the curved dual-speaker flow guide 310 or even the dual-speaker flow guide 315 with a gradually varying curvature further includes a throat 310c; the throat 310c is hollow inside and open at both ends, forming a cylindrical shape; the ends of the throat 310c are respectively connected to the small-mouth end 310b of the first speaker 311 and the small-mouth end 310b of the second speaker 312; the small-mouth ends 310b of the first speaker 311 and the second speaker 312 smoothly transition with the throat 310c.

[0218] The throat 310c can be cylindrical, with a straight cross-section parallel to the central axis X. This allows cold air to flow from the first speaker 311 to the second speaker 312 along the central axis, effectively guiding the cold air. Furthermore, the cylindrical shape of the throat 310c facilitates the central fixation of the curved dual-speaker flow guide 310 by a clamp. Because the interiors of the first and second speakers 311, 312 are concave, the length of the throat 310c can be minimized. This allows for smoother guidance of the cold air from the first speaker 311, the throat 310c, and the second speaker 312, thereby enhancing the cold air guidance effect.

[0219] Of course, the throat 310c can also adopt an inward-concave arc surface, and the curvature change rule of the arc surface is different from that of the first speaker 311 and the second speaker 312. In this way, the guiding process of the cold air in the curved double-speaker body guide member 310 will be smoother, further improving the guiding effect of the cold air.

[0220] As shown in Figure 9, the inner wall of the curved dual-horn flow guide 310, or even the curvature-gradient dual-horn flow guide 315, is further provided with a plurality of guiding warps 313 or guiding wefts 314. The inner wall of the curvature-gradient dual-horn flow guide 315 is provided with a plurality of guiding warps 313, which extend from the wide-mouth end 310a of the first horn 311 toward the wide-mouth end 310a of the second horn 312. On the same vertical plane of the central axis of the curvature-gradient dual-horn flow guide 315, the spacing between two adjacent guiding warps 313 is equal. In this solution, the guiding warps 313 further enhance the guiding effect of the energy source 600 on the cold air in the human body. After the cold air is drawn out of the human body, it is directed and guided by the guiding warps 313, allowing it to pass through the flow guide better and faster, thereby improving the efficiency of cold air discharge.

[0221] In the extension direction from the center to the two ends of the double-horn flow guide 315 with gradually changing curvature, the distance between adjacent guiding meridians 313 gradually increases.

[0222] In another embodiment, the inner wall of the double-flared flow guide 315 with a gradual curvature is further provided with a plurality of guide wefts 314. These guide wefts 314 surround the central axis of the channel and are spaced apart along the central axis of the channel. In this embodiment, concentric guide wefts 314 are added to the inner wall of the double-flared flow guide 315 with a diameter that decreases from the large end 310a of the flared body to the small end 310b. This step-by-step closed-loop structure enhances the attraction of cold air from the large end 310a to the small end 310b, making the discharge of cold air more pronounced and further ensuring the stability of the connection between the cold air and the energy source 600.

[0223] The spacing between adjacent guide wefts 314 gradually increases along the direction extending from the center of the gradually curvatured dual-flared flow guide 315 toward its ends. In this embodiment, the smaller the spacing between adjacent guide wefts 314, the stronger the attraction to cold air; conversely, the smaller the spacing, the weaker the attraction. To ensure a smooth transition in the cold air guidance process, the flow guide's attraction to cold air should increase from its ends to its center. This allows the cold air to enter the flow guide at a gradually accelerated rate after exiting the human body, and then be directed toward the energy source 600 at a gradually decelerated rate, resulting in a more stable cold air guidance process.

[0224] It is understood that the aforementioned guide wefts 314 and guide warps 313 can be used alone or in combination, and can be used alone or in combination on the curved double-flared flow guide 310. The guide warps 313 and guide wefts 314 are each formed by forming grooves on the inner wall.

[0225] In one embodiment of a combined use, the inner wall of the gradually curving dual-horn flow guide 315 is provided with a plurality of guiding warps 313 and a plurality of guiding wefts 314. The plurality of guiding warps 313 extend from the wide-mouth end 310a of the first horn 311 toward the wide-mouth end 310a of the second horn 312. On the same vertical plane perpendicular to the central axis of the gradually curving dual-horn flow guide 315, the spacing between two adjacent guiding warps 313 is equal. The guiding wefts 314 surround the central axis of the gradually curving dual-horn flow guide 315 and are spaced apart along the central axis. The guiding wefts 314 are staggered with the guiding warps 313.

[0226] As shown in Figure 10, the outer wall of the gradually changing curvature dual-flared flow guide 315 is concave toward the central axis, and the wall thickness of the gradually changing curvature dual-flared flow guide 315 increases gradually from the ends toward the center. In this embodiment, the shape of the outer wall of the gradually changing curvature dual-flared flow guide 315 is roughly the same as the shape of the inner wall. The flow guide is larger at the ends and thinner in the middle, which makes it structurally unstable. Deformation is more likely to occur closer to the edges. Increasing the overall wall thickness would increase the production cost of the flow guide. Making the edges thicker and the middle thinner would result in a heavy-ends-light center, which could easily cause the gradually changing curvature dual-flared flow guide 315 to break in the middle. Therefore, by gradually increasing the wall thickness of the gradually changing curvature dual-flared flow guide 315 from the edges to the middle, the degree of deformation at the edges can be effectively reduced, while also increasing the structural strength of the middle portion of the gradually changing curvature dual-flared flow guide 315 and preventing breakage. Furthermore, compared with increasing the overall wall thickness, this approach offers lower costs and better diversion effects.

[0227] As shown in Figure 11 , the double-flared flow guide 315 with a gradually varying curvature can also be formed using a shell with a uniform thickness. Specifically, the outer wall of the double-flared flow guide 315 is recessed toward the central axis, and the wall thickness of the double-flared flow guide 315 is consistent at all locations. The uniform wall thickness of the double-flared flow guide 315, consistent inside and outside, can enhance its ability to guide cold air.

[0228] It is understandable that, under the premise that the curvature gradient double-flared body flow guide 315 meets the strength requirements, the smaller the wall thickness difference is, the better; the thinner the overall thickness is, the better.

[0229] Regarding the material of the curved dual-flared deflector 310, the inventors discovered that non-transparent materials have a stronger attraction to cold air. When using a deflector made of non-transparent materials, cold air is significantly retained when passing through the curved dual-flared deflector 310, affecting the smooth passage of subsequent cold air. Over time, the deflection capacity decreases. Using a transparent material, however, reduces cold air retention and allows for long-term use.

[0230] In light of the above concept, the curved dual-flared flow guide 310 in this embodiment can be formed from a transparent material. The transparent material can be transparent plastic, and small quantities can be produced using 3D printing. However, 3D printing suffers from poor structural stability and can significantly deform after prolonged use. The larger the curved dual-flared flow guide 310, the more severe the deformation, resulting in higher costs and uneconomical mass production. Therefore, the curved dual-flared flow guide 310 in this embodiment can be produced using a mold. Large-scale production uses a fixed mold, which provides stability, a better finished product, and lower costs.

[0231] Example 2: Series flow guide components

[0232] The flow guide module 300 provided as the second embodiment of the present application is a serial flow guide component 320, the two ends of the serial flow guide component 300 are open and the interior is hollow to form a channel, the serial flow guide component 320 includes at least two curvature gradient double-horn flow guide pieces 315 arranged in parallel in sequence, and the channel is formed by connecting the channels of all the curvature gradient double-horn flow guide pieces 315; in the serial flow guide component 320, the large mouth ends 310a of two adjacent curvature gradient double-horn flow guide pieces 315 are arranged opposite to each other; in the serial flow guide component 320, along the central axis direction of the curvature gradient double-horn flow guide piece 315, the large mouth ends 310a of two adjacent curvature gradient double-horn flow guide pieces 315 at least partially overlap.

[0233] The structure of the double-flared air guide 315 with gradually varying curvature is similar to that described in the first embodiment and will not be elaborated on here.

[0234] It should be understood that each of the curvature gradient double-horn body flow guide pieces 315 is a completely separate and independent structure and will not be nested together. It can also be understood that in the direction perpendicular to the central axis of the curvature gradient double-horn body flow guide piece 315, the positive projections of each curvature gradient double-horn body flow guide piece 315 will not overlap with each other.

[0235] It can be understood that no matter whether the sizes of two adjacent double-flared body flow guide pieces 315 with gradual curvature are the same, and no matter whether the central axes of two adjacent double-flared body flow guide pieces 315 with gradual curvature are on the same straight line, in two adjacent double-flared body flow guide pieces 315 with gradual curvature, the relative large-mouth ends 310a will have a portion facing and overlapping.

[0236] To facilitate understanding, the following example illustrates the overlapping structure of adjacent dual-flared flow guides 315 with a gradual curvature. When projecting a single dual-flared flow guide 315 along its central axis, the outer contour of each dual-flared flow guide 315 forms a circle. When projecting two adjacent dual-flared flow guides 315, the outer contours of the two dual-flared flow guides 315 either remain a single circle or form a ring-like structure resembling a figure-eight. When the projection of the outer contours of two adjacent double-flared-curvature air guides 315 is reduced to a circle, this indicates that the two double-flared-curvature air guides 315 are equal in size and their central axes are collinear. Alternatively, the two double-flared-curvature air guides 315 are unequal in size, but the projection of the larger double-flared-curvature air guide 315 completely covers the projection of the smaller double-flared-curvature air guide 315. When the projection of the outer contours of two adjacent double-flared-curvature air guides 315 forms a ring structure similar to a figure-8, this indicates that the central axes of the two double-flared-curvature air guides 315 are not collinear, but their projections partially overlap.

[0237] The inventors have found that when cold air passes through the central area inside the double-horn body guide member 315 with gradually varying curvature, the passage becomes narrower, causing the passing cold air to converge; after the cold air passes through the central area, the passage becomes wider, causing the cold air to tend to disperse.

[0238] By employing the technical means of the embodiments of the present application, at least two curvature-gradient dual-flared body guides 315 are connected in series to form a series guide assembly 320. After the cold air is initially gathered by the previous curvature-gradient dual-flared body guide 315, the subsequent curvature-gradient dual-flared body guide 315 converges the dispersed cold air from the previous curvature-gradient dual-flared body guide 315 a second time. After these two convergences, the cold air has a stronger tendency to move along the axis toward the energy source 600, making it less likely for the cold air to attenuate during movement. Compared to a single curvature-gradient dual-flared body guide 315, the cold air that passes through the series guide assembly 320 in this solution, due to multiple convergences, ultimately disperses less cold air, has a stronger connection with the energy source 600, and is more stable. During movement, the secondary convergence of the subsequent curvature gradient dual-flared flow guide 315 stabilizes the flow of the preceding curvature gradient dual-flared flow guide 315. The preceding curvature gradient dual-flared flow guide 315 is less affected by changes in the external environment and is more stable during movement. In summary, the use of the series flow guide assembly 320 itself can enhance the guiding effect of cold air, while also stabilizing the connection between cold air and energy source 600 during movement, thereby improving the effectiveness of removing cold air.

[0239] For the convenience of explanation and understanding, the embodiment of the present application is described in detail by taking two double-horn flow guide members 315 with gradually varying curvatures to form a series flow guide assembly 320 as an example.

[0240] As shown in FIG. 12 , as one implementation in the embodiment of the present application, the central axes of the two double-flared flow guide members 315 with gradually varying curvatures are on the same straight line.

[0241] When the central axes of all the double-horn body flow guides 315 with gradual curvature in the series flow guide assembly 320 are located on the same straight line, regardless of whether the sizes of these double-horn body flow guides 315 with gradual curvature are the same, under the attraction of the energy source 600, the cold air can converge in the same straight line direction in the series flow guide assembly 320, thereby further enhancing the convergence effect of the cold air and reducing the degree of connection attenuation between the energy source 600 and the cold air.

[0242] In this embodiment, the two double-horn flow guides 315 with gradually varying curvatures have the same shape and size.

[0243] It should be understood that "same shape" means that the two double-flared flow guide members 315 with gradual curvature have the same outline and proportions between their parts; "equal size" means that the two double-flared flow guide members 315 with gradual curvature have the same dimensions in terms of the diameter of the large end 310a, the diameter of the small end 310b, the length, etc.

[0244] Since all the curvature gradient double-horn body guide pieces 315 of the series guide assembly 320 have the same shape and are equal in size, that is, all the curvature gradient double-horn body guide pieces 315 are exactly the same, each curvature gradient double-horn body guide piece 315 has the same effect of guiding the cold air, and the cold air will not produce sudden changes when passing through the series guide assembly 320, so that the cold air can pass through the series guide assembly 320 more smoothly.

[0245] Furthermore, when the number of gradually changing curvature dual-horn body guides 315 within the series flow guide assembly 320 exceeds three, the spacing between adjacent gradually changing curvature dual-horn body guides 315 is also uniform. This allows the cold air to pass through each gradually changing curvature dual-horn body guide 315 at a consistent rhythm, and also between two adjacent gradually changing curvature dual-horn body guides 315 at a consistent rhythm. With the spacing between each gradually changing curvature dual-horn body guide 315 and the next gradually changing curvature dual-horn body guide 315 as a unit, when pulled by the series flow guide assembly 320, the cold air's rhythm within each unit is consistent and constant, thus making the cold air more stable within the series flow guide assembly 3201. In actual use, it is necessary to first establish stability between the series flow guide assembly 320 and the cold air in the human body, and then, by moving the series flow guide assembly 320, pull the cold air in the human body outward, thereby achieving the effect of eliminating the cold air in the human body.

[0246] As shown in FIG13 , there is a spacing between adjacent double-flared flow guide pieces 315 with a gradual curvature, the spacing between adjacent double-flared flow guide pieces 315 with a gradual curvature is D, and the diameter of the large mouth end 310a of the double-flared flow guide piece 315 with a gradual curvature is φ1; wherein D is equal to 0.5φ1.

[0247] Since the curvature gradient double-horn body guide pieces 315 in the serial guide assembly 320 are arranged in sequence at intervals, by retaining the spacing between adjacent curvature gradient double-horn body guide pieces 315, the cold air can diffuse through the previous level curvature gradient double-horn body guide piece 315 (the curvature gradient double-horn body guide piece 315 in the serial guide assembly 320 that is closer to the human body), and can diffuse out of the overlapping range of the large mouth ends 310a of the adjacent curvature gradient double-horn body guide pieces 315, and diffuse out from the spacing between the two, thereby improving the diffusion effect of the cold air and allowing the cold air to fully disperse, so as to form sufficient negative pressure to attract more cold air into the previous level curvature gradient double-horn body guide piece 315.

[0248] Correspondingly, due to the spacing between the rear-stage, gradually changing, dual-flared-body guide 315 (the one closer to the energy source 600 in the series-connected guide assembly 320), there is sufficient space to collect the cold air exiting the preceding, gradually changing, dual-flared-body guide 315. This allows the cold air to flow more smoothly from the preceding, gradually changing, dual-flared-body guide 315 to the rear-stage, gradually changing, dual-flared-body guide 315, reducing the risk of cold air leaking out. Due to the spacing between the two, gradually changing, dual-flared-body guides 315 can create a combined force, enhancing the guiding effect.

[0249] Furthermore, if the spacing D between adjacent gradient-curvature dual-flared flow guides 315 is too small, cold air can easily accumulate between the two adjacent gradient-curvature dual-flared flow guides 315, hindering the flow of cold air. If D is too large, the subsequent gradient-curvature dual-flared flow guide 315 cannot fully collect the cold air flowing from the previous gradient-curvature dual-flared flow guide 315, causing the cold air to escape and reducing the stability of the connection between the energy source 600 and the cold air. Through repeated debugging and testing, the inventors found that controlling D to 0.5φ1 achieves better guiding effect for the series flow guide assembly 320.

[0250] The inventors also found that if the ratio of the spacing D between adjacent double-flared body flow guides 315 with gradual curvature and the diameter φ1 of the large mouth end 310a of the double-flared body flow guide 315 is appropriately adjusted so that D is between 0.3φ1 and 0.8φ1, the guiding effect of the series flow guide assembly 320 can still be maintained at a good level.

[0251] Expanded testing revealed that when D is greater than or equal to 0.1φ1 and less than or equal to 1.5φ1, the overall guiding effect of the series guide assembly 320 is superior to that of a single, dual-flared, curvature-varying horn-shaped guide 315. While the guiding effect is worse when D is 0.1φ1 and 1.5φ1 than when D is 0.3φ1, 0.5φ1, and 0.8φ1, it still does not obstruct the flow of cold air or allow it to escape. Therefore, any configuration with D greater than or equal to 0.1φ1 and less than or equal to 1.5φ1 is considered within the scope of protection of this application.

[0252] In an embodiment of the present application, as shown in Figure 14, taking a double-flared body flow guide 315 with a gradual curvature in the series flow guide assembly 320 as an example, the diameter of the through hole at the center of the double-flared body flow guide 315 with a gradual curvature (φ0): the diameter of the large mouth end 310a of the double-flared body flow guide 315 with a gradual curvature (φ1): the length (L) of the double-flared body flow guide 315 with a gradual curvature, is equal to 1:9.8:5.2.

[0253] Since the larger the diameter φ1 of the large mouth end 310a of the curvature gradient double-horn body guide 315, the more cold air is gathered, and since the smaller the diameter φ0 of the through hole at the center of the curvature gradient double-horn body guide 315, the better the effect of gathering the cold air, if the ratio between the diameter φ1 of the large mouth end 310a of the curvature gradient double-horn body guide 315 and the diameter φ0 of the through hole at the center is too large, the diameter φ0 of the through hole at the center of the curvature gradient double-horn body guide 315 is very small relative to the diameter φ1 of the large mouth end 310a of the curvature gradient double-horn body guide 315, so that the cold air gathered by the curvature gradient double-horn body guide 315 per unit time exceeds the cold air passing through it per unit time, causing the cold air to accumulate at the center of the channel of the curvature gradient double-horn body guide 315. If the ratio between the diameter φ1 of the large opening 310a of the gradually changing double-flared flow guide 315 and the diameter φ0 of the central through hole is too small, the diameter φ0 of the central through hole of the gradually changing double-flared flow guide 315 will be relatively close to the diameter φ1 of the large opening 310a of the gradually changing double-flared flow guide 315, and the shape of the gradually changing double-flared flow guide 315 will develop in the direction of a circular tube. This will lead to a decrease in the ability of the gradually changing double-flared flow guide 315 to gather cold air, and thus weaken the ability of the gradually changing double-flared flow guide 315 to guide cold air. Similarly, if the ratio of the diameter to length of the large opening 310a of the gradually changing double-flared flow guide 315 is too large, cold air will easily accumulate in the center of the channel; if it is too small, the ability to guide cold air will be weakened.

[0254] Therefore, through experimental verification and comparison, by controlling the size ratio of the curvature gradient double-horn body guide 315, so that φ0:φ1:L is equal to 1:9.8:5.2, the cold air is not easy to accumulate in the center of the channel, and will not weaken the guiding ability of the cold air.

[0255] Furthermore, by adjusting the ratio of φ0, φ1, and L to achieve a ratio of φ0:φ1:L equal to 1:7-13:2-8, the curvature-gradient dual-flared flow guide 315 can still achieve a good guiding effect. Therefore, when φ0:φ1:L is equal to 1:7-13:2-8, it also meets the design requirements for the curvature-gradient dual-flared flow guide 315 in the embodiment of this application and is also within the scope of protection of this application.

[0256] It should be understood that the “through hole at the center” of the double-flared air guide member 315 with gradually varying curvature refers to the minimum diameter of the internal passage of the double-flared air guide member 315 with gradually varying curvature.

[0257] When the first speaker 311 and the second speaker 312 are directly connected, the “through hole at the center” refers to the connection between the first speaker 311 and the second speaker 312 , and can also be represented as the small mouth end 310 b of the first speaker 311 or the small mouth end 310 b of the second speaker 312 .

[0258] When the first horn 311 and the second horn 312 are connected through the throat 310 c , the “through hole at the center” refers to the through hole at the narrowest part of the throat 310 c of the double-horn flow guide 315 with gradually varying curvature.

[0259] Of course, it can also be expressed in other ways, but none of them affect the specific position of the "through hole at the center" of the double-horn body flow guide 315 with gradual curvature.

[0260] As shown in Figure 15, as the second embodiment of the present application, in this embodiment, the central axes of the two curvature gradient double-horn body flow guides 315 may not be on the same axis, but along the central axis direction of the curvature gradient double-horn body flow guide 315, the through holes at the center of the two curvature gradient double-horn body flow guides 315 at least partially overlap.

[0261] In this embodiment, even if the central axes of all the curvature gradient double-horn body guide members 315 in the series guide assembly 320 are not on the same straight line, since the central through holes of these curvature gradient double-horn body guide members 315 at least partially overlap, that is, the middle channel areas of the curvature gradient double-horn body guide members 315 at least partially overlap, the orthographic projection of the series guide assembly 320 in the direction of its central axis will have a part of the hollow area caused by the overlapping central through holes of these curvature gradient double-horn body guide members 315, so that a straight channel is formed inside the series guide assembly 320. In this way, under the attraction of the energy source 600, the cold air can move from the overlapping central through holes of these curvature gradient double-horn body guide members 315 in turn, so that the cold air can pass more smoothly.

[0262] As shown in Figure 16, as the third embodiment of the present application, in this embodiment, the central axes of all the double-flared flow guide pieces 315 with gradual curvature in the series flow guide assembly 320 are on the same straight line, and the large mouth ends 310a between adjacent double-flared flow guide pieces 315 with gradual curvature are in contact with each other.

[0263] In this embodiment, all the curvature gradient double-horn body guide members 315 in the series guide assembly 320 are arranged in sequence front to back, and all the curvature gradient double-horn body guide members 315 are the same. At this time, the edges of the large mouth ends 310a of two adjacent curvature gradient double-horn body guide members 315 are fitted together, and the cold air passing through the series guide assembly 320 is confined to the internal channel to avoid escaping from between adjacent curvature gradient double-horn body guide members 315, so that the cold air can only move toward the direction of the energy source 600 and will not overflow in the middle, so the connection between the cold air and the energy source 600 will not be weakened, thereby improving the stability of the connection between the energy source 600 and the cold air.

[0264] Specifically, in this embodiment, two adjacent double-flared flow guide members 315 with gradually varying curvatures can be fixed together by bonding, clamping, or the like. When two adjacent double-flared flow guide members 315 with gradually varying curvatures are fixed together by bonding, glue can be applied to the inner surface of the wide-mouthed end 310a of the double-flared flow guide member 315 to fix the two adjacent double-flared flow guide members 315 from the inside. Alternatively, the wide-mouthed end 310a of the two adjacent double-flared flow guide members 315 can be bonded together from the outside using adhesive tape.

[0265] Furthermore, as shown in Figure 17, in the above embodiment, a sealing box 326 can be added to the series guide assembly 320 to fix all the double-horn guide parts 315 with gradual curvature inside the sealing box 326, and the front and rear ends of the sealing port are corresponding to the positions of the two ends of the series guide assembly 320. The hollow portion 3261 is formed by a plurality of through-hole arrays.

[0266] Among them, the series guide component 320 combined with the sealing box 326 can be sold and used as a separate part or product, which is convenient for taking and placing, and avoids the problem of the single curvature gradient double-horn body guide part 315 in the series guide component 320 falling off; moreover, since the entire series guide component 320 is inside the sealing box 326, it can prevent dust and stains from entering the series guide component 320 and affecting the guide effect of the series guide component 320.

[0267] In addition, in the embodiment of the present application, the number of double-horn body flow guides 315 with gradual curvature in the series flow guide assembly 320 is not limited to two, but can be three, four, five, or even more, because the more double-horn body flow guides 315 with gradual curvature in series in the series flow guide assembly 320, the more stable the connection between the cold air and the energy source 600.

[0268] However, the greater the number of dual-flared flow guides 315 with gradually varying curvatures in series within the series flow guide assembly 320, the larger the volume of the entire series flow guide assembly 320. Furthermore, considering that a smaller number of dual-flared flow guides 315 with gradually varying curvatures in series within the series flow guide assembly 320 could result in insufficient stabilization of the cold air by the entire series flow guide assembly 320, the inventors have determined that a range of 3-5 dual-flared flow guides 315 with gradually varying curvatures in the series flow guide assembly 320 is optimal, ensuring stability between the cold air and the energy source 600 while also preventing the entire series flow guide assembly 320 from being excessively large. Furthermore, a range of 3 dual-flared flow guides 315 with gradually varying curvatures in the series flow guide assembly 320 achieves even better stabilization.

[0269] As a fourth embodiment of the present application, at least two of the dual-flared flow guides 315 with gradually varying curvatures within the series flow guide assembly 320 have unequal sizes, i.e., at least two different sizes of dual-flared flow guides 315 are present within the series flow guide assembly 320. The series flow guide assembly 320 contains at least three dual-flared flow guides 315 with gradually varying curvatures, and the sizes of the dual-flared flow guides 315 at either end of the series flow guide assembly 320 are equal, and are greater than or equal to the size of the dual-flared flow guide 315 between the two ends. Furthermore, within the series flow guide assembly 320, the wide-mouthed ends 310a of two adjacent dual-flared flow guides 315 with gradually varying curvatures are disposed opposite each other, and along the central axis of the dual-flared flow guide 315, the wide-mouthed ends 310a of the two adjacent dual-flared flow guides 315 at least partially overlap.

[0270] When the size of the curvature gradient double-horn body guide 315 is larger, more cold air can be gathered. When the size of the curvature gradient double-horn body guide 315 is smaller, the cold air can be more concentrated, thereby improving the stability of the connection between the cold air and the energy source 600. Therefore, this embodiment adopts a larger curvature gradient double-horn body guide 315 and a smaller curvature gradient double-horn body guide 315 to form a series guide component 320, so that the series guide component 320 has the effect of gathering more cold air and making the cold air more concentrated.

[0271] As shown in FIG18 , for the convenience of explanation and understanding, this embodiment uses the example that the series guide assembly 320 is composed of three double-horn guide pieces 315 with gradually varying curvatures, and these three double-horn guide pieces 315 with gradually varying curvatures are of two different sizes for explanation.

[0272] Specifically, there are three curvature gradient double-horn body guide pieces 315 in the series guide assembly 320, and the three curvature gradient double-horn body guide pieces 315 are respectively a first curvature gradient double-horn body guide piece 321, a second curvature gradient double-horn body guide piece 322 and a third curvature gradient double-horn body guide piece 323. The second curvature gradient double-horn body guide piece 322 is arranged between the first curvature gradient double-horn body guide piece 321 and the third curvature gradient double-horn body guide piece 323; wherein, the size of the first curvature gradient double-horn body guide piece 321 is equal to the size of the third curvature gradient double-horn body guide piece 323, and both are larger than the size of the second curvature gradient double-horn body guide piece 322.

[0273] In the series flow guide assembly 320, the larger, gradually changing curvature dual-horn flow guide 315 is placed on the outside, so that the larger, gradually changing curvature dual-horn flow guide 315 faces the human body and the energy source 600. Therefore, the gradually changing curvature dual-horn flow guide 315 facing the human body can gather cold air over a larger area, and the gradually changing curvature dual-horn flow guide 315 facing the energy source 600 can allow the cold air to establish contact with the energy source 600 over a larger area, allowing the cold air and the energy source 600 to fully contact each other, thereby making the connection between the two more stable. The smaller, gradually changing curvature dual-horn flow guide 315 located inside the series flow guide assembly 320 can further gather and concentrate the cold air passing through, making it less likely to be interrupted during the movement of the cold air within the series flow guide assembly 320.

[0274] In this embodiment, the series guide assembly 320 is composed of three double-horn guide pieces 315 with gradual curvature connected in series, and the double-horn guide pieces 315 with gradual curvature connected at both ends are larger in size, while the double-horn guide piece 315 with gradual curvature connected in the middle is smaller in size, so that the series guide assembly 320 can gather cold air in a larger range, make the connection between the two more stable, and make the cold air less likely to be interrupted during the movement in the series guide assembly 320, while also reducing the volume of the entire series guide assembly 320.

[0275] In an embodiment, the central axes of the three double-horn body flow guides 315 with gradual curvature are on the same straight line. Under the attraction of the energy source 600, the cold air can converge in the same straight line direction in the series flow guide assembly 320, thereby further enhancing the convergence effect of the cold air and reducing the degree of connection attenuation between the energy source 600 and the cold air.

[0276] In an embodiment of the present application, the spacing between adjacent curvature gradient double-flare flow guide pieces 315 is related to the size of the curvature gradient double-flare flow guide piece 315. Specifically, when the size of the larger curvature gradient double-flare flow guide piece 315 (the first curvature gradient double-flare flow guide piece 321 or the third curvature gradient double-flare flow guide piece 323) remains unchanged, the larger the diameter of the large mouth end 310a of the smaller curvature gradient double-flare flow guide piece 315 (the second curvature gradient double-flare flow guide piece 322), the larger the spacing between the smaller curvature gradient double-flare flow guide piece 315 and the adjacent larger curvature gradient double-flare flow guide piece 315.

[0277] Since the smaller the size of the curvature gradient double-horn body guide piece 315, the smaller the diameter of its large mouth end 310a, and the worse the ability to gather cold air, it is necessary to place it closer to the adjacent large-sized curvature gradient double-horn body guide piece 315 to fully gather the cold air emitted by the previous level adjacent large-sized curvature gradient double-horn body guide piece 315; on the contrary, if the size of the curvature gradient double-horn body guide piece 315 is larger, the larger the diameter of its large mouth end 310a, and the better the ability to gather cold air, if it is too close to the adjacent large-sized curvature gradient double-horn body guide piece 315, it will hinder the dispersion of the cold air coming out of the previous level curvature gradient double-horn body guide piece 315, so it needs to be placed farther away from the adjacent large-sized curvature gradient double-horn body guide piece 315.

[0278] Specifically, when the diameter of the large mouth end 310a of the smaller-sized double-flare flow guide 315 with a gradual curvature increases by 1 times, the distance between the smaller-sized double-flare flow guide 315 with a gradual curvature and the adjacent larger-sized double-flare flow guide 315 with a gradual curvature increases by greater than or equal to 1.5 times and less than or equal to 3 times.

[0279] Moreover, the inventors have further discovered that when the diameter of the large mouth end 310a of the smaller-sized double-flare flow guide 315 with a gradual curvature is increased by 1 times, and the distance between the smaller-sized double-flare flow guide 315 with a gradual curvature and the adjacent larger-sized double-flare flow guide 315 with a gradual curvature is increased by 2 times, the series flow guide assembly 320 has a better effect on gathering cold air.

[0280] In an embodiment, the smaller-sized curvature gradient double-horn body guide piece 315 is a scaled version of the larger-sized curvature gradient double-horn body guide piece 315. Therefore, all the curvature gradient double-horn body guide pieces 315 in the series guide assembly 320 have the same appearance, but different sizes. In this way, the curvature gradient double-horn body guide pieces 315 have better consistency, and there is no obvious mutation in the flow of cold air between different curvature gradient double-horn body guide pieces 315. The cold air runs more smoothly and has better stability with the energy source 600.

[0281] Furthermore, as shown in Figure 19, the size ratio of the larger curvature gradient double horn body guide piece 315 and the smaller curvature gradient double horn body guide piece 315 is 5:1, which can make the cold air have good stability in the series guide assembly 320; at the same time, the distance (D) between the larger curvature gradient double horn body guide piece 315 and the adjacent smaller curvature gradient double horn body guide piece 315 is equal to 1.5 times the diameter (φ11) of the large mouth end 310a of the smaller curvature gradient double horn body guide piece 315.

[0282] If the distance between the larger curvature gradient double horn body guide piece 315 and the adjacent smaller curvature gradient double horn body guide piece 315 is too small, the cold air will easily accumulate between the two curvature gradient double horn body guide pieces 315, hindering the circulation of the cold air; if the distance between the larger curvature gradient double horn body guide piece 315 and the adjacent smaller curvature gradient double horn body guide piece 315 is too large, the latter stage curvature gradient double horn body guide piece 315 cannot completely gather the cold air flowing out of the former stage curvature gradient double horn body guide piece 315, causing the cold air to escape and reduce the stability of the connection between the energy source 600 and the cold air; it has been verified that for the curvature gradient double horn body guide pieces 315 of different sizes connected in series, making D equal to 1.5φ11, it can not only avoid the accumulation of cold air, but also make the connection between the energy source 600 and the cold air more stable.

[0283] Further verification revealed that when the ratio of the larger curvature gradient dual-flare flow guide 315 to the smaller curvature gradient dual-flare flow guide 315 is between 2-8:1, the spacing (D) between the larger curvature gradient dual-flare flow guide 315 and the adjacent smaller curvature gradient dual-flare flow guide 315 is controlled to be greater than or equal to 0.8 times the diameter (φ11) of the large end 310a of the smaller curvature gradient dual-flare flow guide 315, and less than or equal to 2.5 times the diameter (φ11) of the large end 310a of the smaller curvature gradient dual-flare flow guide 315, that is, 0.8φ11≤D≤2.5φ11. In this case, the series flow guide assembly 320 can ensure stability between the energy source 600 and the cold air, and therefore this range also falls within the protection scope of the embodiments of the present application; preferably, 0.8φ11≤D≤2.5φ11.

[0284] As the fifth embodiment in the embodiments of the present application, as shown in Figure 20, the series guide assembly 320 has five series-connected curvature gradient double-horn body guide pieces 315. Specifically, the series guide assembly 320 is composed of a first curvature gradient double-horn body guide piece 321, a second curvature gradient double-horn body guide piece 322, a third curvature gradient double-horn body guide piece 323, a fourth curvature gradient double-horn body guide piece 324 and a fifth curvature gradient double-horn body guide piece 325, wherein the first curvature gradient double-horn body guide piece 321, the third curvature gradient double-horn body guide piece 323 and the fourth curvature gradient double-horn body guide piece 324 are equal in size, and the second curvature gradient double-horn body guide piece 322 and the fifth curvature gradient double-horn body guide piece 325 are equal in size.

[0285] Moreover, the second curvature gradient double horn body flow guide 322 is arranged between the first curvature gradient double horn body flow guide 321 and the third curvature gradient double horn body flow guide 323, the fourth curvature gradient double horn body flow guide 324 is located between the first curvature gradient double horn body flow guide 321 and the second curvature gradient double horn body flow guide 322, and the fifth curvature gradient double horn body flow guide 325 is located between the first curvature gradient double horn body flow guide 321 and the fourth curvature gradient double horn body flow guide 324; that is, in the series flow guide assembly 320, the first curvature gradient double horn body flow guide 321, the fifth curvature gradient double horn body flow guide 325, the fourth curvature gradient double horn body flow guide 324, the second curvature gradient double horn body flow guide 322 and the third curvature gradient double horn body flow guide 323 are connected in series in sequence.

[0286] In this embodiment, the series guide assembly 320 is composed of five double-horn body guide pieces 315 with gradual curvature connected in series, and a double-horn body guide piece 315 with gradual curvature is sandwiched between every two double-horn body guide pieces 315 with gradual curvature, which is larger in size. This allows the cold air to enter the series guide assembly 320 and go through five processes of dispersion, convergence, dispersion, convergence, and dispersion. After the cold air passes through the convergence and compression of the two double-horn body guide pieces 315 with gradual curvature, it will be more stable during the movement. Moreover, a double-horn body guide piece 315 with gradual curvature, which is larger in size, is sandwiched between the two double-horn body guide pieces 315 with gradual curvature, which allows the cold air to pass through the double-horn body guide piece 315 with gradual curvature, and then be fully gathered together again by the double-horn body guide piece 315 with gradual curvature, thereby reducing the cold air that escapes from between the two double-horn body guide pieces 315 with gradual curvature, which is smaller in size.

[0287] Of course, in the embodiment of the present application, the curvature gradient double-horn body guide member 315 in the above-mentioned series guide assembly 320 can also adopt other series combination forms, such as using a larger number of curvature gradient double-horn body guide members 315, or using more curvature gradient double-horn body guide members 315 of different sizes, or adjusting the arrangement of the curvature gradient double-horn body guide member 315 in the above-mentioned embodiment to other styles (for example: adopting a large size-large size-small size series mode). Due to too many implementation methods, they are not displayed here one by one.

[0288] Example 3: Nested diversion components

[0289] The flow guide module 300 provided as the third embodiment of the present application is a nested flow guide assembly 330. The nested flow guide assembly 330 is open at both ends and hollow inside, forming a channel. The nested flow guide assembly 330 includes at least two stages of gradually changing curvature dual-flared flow guide members 315. The gradually changing curvature dual-flared flow guide members 315 of different stages have different sizes, and the gradually changing curvature dual-flared flow guide members 315 of the next stage are nested within the gradually changing curvature dual-flared flow guide members 315 of the previous stage. The channel of the nested flow guide assembly 330 is the channel within the smallest gradually changing curvature dual-flared flow guide member 315. In the nested flow guide assembly 330, when viewed along the central axis of the gradually changing curvature dual-flared flow guide member 315 of the previous stage, the through-holes of the gradually changing curvature dual-flared flow guide member 315 of the previous stage and the gradually changing curvature dual-flared flow guide member 315 of the next stage at the narrowest point of the channel at least partially overlap.

[0290] As shown in Figure 21, as the first implementation in the embodiment of the present application, the nested guide assembly 330 is a two-stage single nested guide assembly 330, specifically including two stages of curvature gradient double-horn body guide parts 315, and the number of curvature gradient double-horn body guide parts 315 in each stage is only one.

[0291] Specifically, the nested guide assembly 330 in the embodiment of the present application is formed by nesting a first curvature gradient double-flare guide piece 321 and a second curvature gradient double-flare guide piece 322. The size of the first curvature gradient double-flare guide piece 331 is smaller than the size of the second curvature gradient double-flare guide piece 332, and the first curvature gradient double-flare guide piece 331 is nested in the second curvature gradient double-flare guide piece 332; moreover, along the central axis direction of the second curvature gradient double-flare guide piece 332, the channel of the first curvature gradient double-flare guide piece 331 and the channel of the second curvature gradient double-flare guide piece 322 completely overlap at the narrowest through-hole position.

[0292] It can be understood that the above-mentioned complete overlap means that the through hole position at the narrowest point of the channel of the first curvature gradient double-horn body guide 321 is located within the area of ​​the through hole at the narrowest point of the channel of the second curvature gradient double-horn body guide 322, and does not mean that the two positions have the same size and the edges overlap.

[0293] For the shapes of the first curvature gradient double-horn body flow guide 331 and the second curvature gradient double-horn body flow guide 332, please refer to the description of the curvature gradient double-horn body flow guide 315 in the first embodiment. For the "through hole at the narrowest part of the channel", please refer to the description in the second embodiment, which will not be repeated here.

[0294] It should be understood that in the embodiments of the present application, "nesting" means: first, the curvature gradient dual-flared flow guide members 315 of different levels must meet the nesting condition; second, the curvature gradient dual-flared flow guide member 315 of the previous level must completely cover the smaller curvature gradient dual-flared flow guide member 315. To facilitate understanding, the present application provides a specific example. From the front of the nested flow guide assembly 330 (along the central axis of the nested flow guide assembly 330), the outer contour of the large end 310a of the second curvature gradient dual-flared flow guide member 332 surrounds the outer contour of the large end 310a of the first curvature gradient dual-flared flow guide member 331, and the large end 310a of the first curvature gradient dual-flared flow guide member 331 does not exceed the range covered by the large end 310a of the second curvature gradient dual-flared flow guide member 332. Viewed from the side of the nested guide assembly 330 (perpendicular to the central axis of the nested guide assembly 330), the second curvature gradient double-flare guide member 332 will completely block the first curvature gradient double-flare guide member 331, so that only the outline shape of the second curvature gradient double-flare guide member 332 can be seen in this direction.

[0295] This embodiment adopts a nested guide assembly 330 composed of a first curvature gradient double-horn body guide piece 331 and a second curvature gradient double-horn body guide piece 332. Since the second curvature gradient double-horn body guide piece 332 has a larger opening and a wider coverage area, it can gather more cold air; and the first curvature gradient double-horn body guide piece 331 has a smaller opening, so that the cold air gathered through the opening of the second curvature gradient double-horn body guide piece 332 enters the first curvature gradient double-horn body guide piece 331, and through secondary guidance, it can enhance the attraction of the cold air, allowing the cold air to pass through the nested guide assembly 330 more stably; at the same time, since the first curvature gradient double-horn body guide piece 331 has a smaller throat 310c, the cold air can be more concentrated. After adopting the nested guide assembly 330, the attraction formed by the double guidance brought by the second curvature gradient double horn body guide piece 332 and the first curvature gradient double horn body guide piece 331 is sufficient to allow more concentrated cold air to pass through the throat 310c of the first curvature gradient double horn body guide piece 331, and then drive the deeper cold air of the human body out into the nested guide assembly 330, which can better clear the root cause of the cold air and make the cold air eliminated more thoroughly, thereby improving the health level of the human body.

[0296] Furthermore, the nested guide assembly 330 in the embodiment of the present application uses a two-stage nested curvature gradient double-horn guide member 315, which is easy to manufacture and has low cost. Furthermore, the entire nested guide assembly 330 is relatively small in size, making it suitable for removing cold air from a specific part of the human body.

[0297] In this embodiment, the center points of the first and second curvature gradient dual-flare flow guides 331 and 332 coincide. With this design, the first and second curvature gradient dual-flare flow guides 331 and 332 converge toward the same central location, concentrating the cold air and thereby drawing out deeper levels of cold air. Furthermore, only one first curvature gradient dual-flare flow guide 331 is nested within the second curvature gradient dual-flare flow guide 332, and the wide-mouth end 310a of the first curvature gradient dual-flare flow guide 331 is close to the throat 310c of the second curvature gradient dual-flare flow guide 332. This creates a more natural arcuate transition between the first and second curvature gradient dual-flare flow guides 331 and 332, making the process of drawing out cold air less susceptible to interference.

[0298] As shown in Figure 22, in this embodiment, the central axis of the first gradually-curved dual-flared air guide 331 coincides with the central axis of the second gradually-curved dual-flared air guide 332. With this design, the second gradually-curved dual-flared air guide 332 and the first gradually-curved dual-flared air guide 331 converge toward the same straight line, directing the cold air along the same straight line. This ensures stable cold air guidance and reduces the risk of interference from the outside environment.

[0299] In this embodiment, the first gradually-varying dual-flared air guide 331 is a scaled-down version of the second gradually-varying dual-flared air guide 332. Because the two gradually-varying dual-flared air guides 315 have the same shape and good consistency, and the inner wall curves of the two gradually-varying dual-flared air guides 315 transition naturally, the cold air is guided more smoothly.

[0300] As shown in Figures 23 and 24, there is an air duct 339 between the first curvature gradient double-flare body guide piece 331 and the second curvature gradient double-flare body guide piece 332. The two ends of the air duct 339 are respectively connected to the outside of the two ends of the nested guide assembly 330, so that the gas can pass between the outer side of the first curvature gradient double-flare body guide piece 331 and the inner side of the second curvature gradient double-flare body guide piece 332.

[0301] Since there is an airway 339 between the two levels of curvature gradient double-horn body guide pieces 315, the first curvature gradient double-horn body guide piece 331 does not block the throat 310c in the middle of the second curvature gradient double-horn body guide piece 332, that is, the first horn 311 and the second horn 312 of the second curvature gradient double-horn body guide piece 332 are still connected, and the second curvature gradient double-horn body guide piece 332 still retains sufficient cold air guiding ability, which can attract cold air into its interior, and then guide the cold air into the second curvature gradient double-horn body guide piece 332, thereby enhancing the guiding effect of cold air.

[0302] For the air duct 339, since the curvature gradient double trumpet body guide 315 is a double trumpet-shaped structure with wide ends and narrow middle, when the first curvature gradient double trumpet body guide 331 is placed in the channel of the second curvature gradient double trumpet body guide 332, since the center points of the first curvature gradient double trumpet body guide 331 and the second curvature gradient double trumpet body guide 332 coincide with each other, the two large mouth ends 310a of the first curvature gradient double trumpet body guide 331 are respectively located at the second curvature gradient double trumpet body guide 332. On both sides of the center point, the first curvature gradient double-flare body flow guide 331 needs to be moved through the minimum through-hole of the channel of the second curvature gradient double-flare body flow guide 332. Therefore, the size of the large mouth end 310a of the first curvature gradient double-flare body flow guide 331 will be smaller than the minimum through-hole diameter of the channel of the second curvature gradient double-flare body flow guide 332, that is, the minimum cross-sectional size of the throat 310c. At this time, an airway 339 will naturally be formed between the first curvature gradient double-flare body flow guide 331 and the second curvature gradient double-flare body flow guide 332.

[0303] Moreover, there is no direct contact between the first curvature gradient double-flare flow guide 331 and the second curvature gradient double-flare flow guide 332. The edges of the large mouth ends 310a at both ends of the first curvature gradient double-flare flow guide 331 are glued and fixed to the inner wall of the second curvature gradient double-flare flow guide 332 by dispensing glue, so that the center lines of the first curvature gradient double-flare flow guide 331 and the second curvature gradient double-flare flow guide 332 coincide.

[0304] Optionally, the edges of the large ends 310a of the first curvature gradient double-flare body flow guide 331 at both ends are fixed to the inner wall of the second curvature gradient double-flare body flow guide 332 through three glue spots 3391, and the angle between two adjacent glue spots 3391 is 120°. While ensuring the stability between the first curvature gradient double-flare body flow guide 331 and the second curvature gradient double-flare body flow guide 332, the area of ​​the airway 339 is avoided from being reduced, which would affect the ability of the second curvature gradient double-flare body flow guide 332 to guide cold air.

[0305] Furthermore, as shown in FIG25 , the distance a between the wide-mouth end 310a of the second gradually-curved double-flared flow guide 332 and the corresponding wide-mouth end 310a of the first gradually-curved double-flared flow guide 331 exceeds one-quarter of the length L of the second gradually-curved double-flared flow guide 332. In this embodiment, after the first gradually-curved double-flared flow guide 331 is nested within the channel of the second gradually-curved double-flared flow guide 332, the end surface of the wide-mouth end 310a of the second gradually-curved double-flared flow guide 332 exceeds half the length of a single flare in the first gradually-curved double-flared flow guide 331. This prevents the end of the first gradually-curved double-flared flow guide 331 from protruding too much, which would prevent the cold air gathered by the second gradually-curved double-flared flow guide 332 from being easily guided into the internal channel of the first gradually-curved double-flared flow guide 331.

[0306] Furthermore, the distance between the wide-mouthed end 310a of the first gradually-curved double-flared flow guide 331 and the corresponding wide-mouthed end 310a of the second gradually-curved double-flared flow guide 332 may also exceed one-third of the length of the second gradually-curved double-flared flow guide 332. Because the distance between the end of the first gradually-curved double-flared flow guide 331 and the corresponding end of the second gradually-curved double-flared flow guide 332 is greater, the distance between the end of the first gradually-curved double-flared flow guide 331 and the inner wall of the second gradually-curved double-flared flow guide 332 is smaller, resulting in a more natural transition between the end of the first gradually-curved double-flared flow guide 331 and the inner wall of the second gradually-curved double-flared flow guide 332, and a smoother cold air guiding process.

[0307] It should be noted that in the embodiment of the present application, when viewed along the central axis of the second curvature gradient double-horn body guide member 332, it is also feasible that the narrowest through-hole of the channel of the first curvature gradient double-horn body guide member 331 only partially overlaps with the narrowest through-hole of the channel of the second curvature gradient double-horn body guide member 332. Similarly, the attraction formed by the double guidance brought by the second curvature gradient double-horn body guide member 332 and the first curvature gradient double-horn body guide member 331 can be utilized to allow more concentrated cold air to pass through the throat 310c of the first curvature gradient double-horn body guide member 331, thereby driving the deeper cold air of the human body out into the nested guide assembly 330. However, due to the offset between the throat 310c of the first curvature gradient double-horn body guide member 331 and the throat 310c of the second curvature gradient double-horn body guide member 332, the stability of the cold air after passing through the nested guide assembly 330 will be slightly poor.

[0308] At this time, the center points of the first curvature gradient double-horn body flow guide 331 and the second curvature gradient double-horn body flow guide 332 do not coincide, and the center lines do not coincide. Even the first curvature gradient double-horn body flow guide 331 may not be a proportional scaled part of the second curvature gradient double-horn body flow guide 332. As long as the first curvature gradient double-horn body flow guide 331 can be nested inside the channel of the second curvature gradient double-horn body flow guide 332, it should fall within the protection scope of this application.

[0309] As shown in FIG26 , as a second embodiment of the present application, the difference from the first embodiment is that this embodiment adopts a three-level nested nested guide assembly, which is a three-level single nested guide assembly. Specifically, the nested guide assembly 330 includes a third curvature gradient double flare guide 333, a fourth curvature gradient double flare guide 334, and a fifth curvature gradient double flare guide 335. The third curvature gradient double flare guide 333 is nested within the fourth curvature gradient double flare guide 334, which is nested within the fifth curvature gradient double flare guide 335. Moreover, when viewed along the central axis of the fifth curvature gradient double flare guide 335, the through-holes of the third curvature gradient double flare guide 333, the fourth curvature gradient double flare guide 334, and the fifth curvature gradient double flare guide 335 overlap at the narrowest point of the channel.

[0310] In this embodiment, the nested guide assembly 330 is formed by nesting three unequally sized, gradually changing curvature, double-flared guide members 315. As the number of levels in the nested guide assembly 330 increases, the nesting becomes more numerous, resulting in a larger outermost layer of gradually changing curvature, double-flared guide members 315 and a smaller innermost layer of gradually changing curvature, double-flared guide members 315. This allows for a larger opening area and a smaller throat 310c diameter, resulting in a better guiding effect for the nested guide assembly 330. However, as the number of nesting levels increases, the size of the nested guide assembly 330 increases significantly, impacting practical use. Therefore, to avoid excessive size for the nested guide assembly 330 while improving its guiding effect, the nested guide assembly 330 is designed as a three-layer nested structure consisting of a third gradually changing curvature, double-flared guide member 333, a fourth gradually changing curvature, double-flared guide member 334, and a fifth gradually changing curvature, double-flared guide member 335.

[0311] Moreover, in this embodiment, the center points of the third curvature gradient double horn body air guide 333, the fourth curvature gradient double horn body air guide 334 and the fifth curvature gradient double horn body air guide 335, the three curvature gradient double horn body air guide 315 coincide, the central axes coincide, and the third curvature gradient double horn body air guide 333 is a scaled version of the fourth curvature gradient double horn body air guide 334, and the fourth curvature gradient double horn body air guide 334 is a scaled version of the fifth curvature gradient double horn body air guide 335, so as to ensure that in the nested guide assembly 330, the convergence direction of the cold air tends to the same straight line, and the arc surface transition of the cold air between two adjacent curvature gradient double horn body air guides 315 is more natural, so that the nested guide assembly 330 has good stability in guiding the cold air and is not easily disturbed by the external environment.

[0312] In addition, there is an air duct 339 between two adjacent levels of curvature gradient double-horn body guide pieces 315. Specifically, there is an air duct 339 between the third curvature gradient double-horn body guide piece 333 and the fourth curvature gradient double-horn body guide piece 334, and there is also an air duct 339 between the fourth curvature gradient double-horn body guide piece 334 and the fifth curvature gradient double-horn body guide piece 335.

[0313] As for the specific formation of the air duct 339, due to the requirements of the assembly method, the third curvature gradient double-flare body flow guide 333 must be inserted into the channel of the fourth curvature gradient double-flare body flow guide 334, and the fourth curvature gradient double-flare body flow guide 334 must be inserted into the channel of the fifth curvature gradient double-flare body flow guide 335. Therefore, the size of the large mouth end 310a of the third curvature gradient double-flare body flow guide 333 is smaller than the size of the narrowest part of the channel of the fourth curvature gradient double-flare body flow guide 334, and the size of the large mouth end 310a of the fourth curvature gradient double-flare body flow guide 334 is smaller than the size of the narrowest part of the channel of the fifth curvature gradient double-flare body flow guide 335. Since there is no contact between the third curvature gradient double horn body flow guide piece 333 and the fourth curvature gradient double horn body flow guide piece 334, and there is no contact between the fourth curvature gradient double horn body flow guide piece 334 and the fifth curvature gradient double horn body flow guide piece 335, two adjacent curvature gradient double horn body flow guide pieces 315 are fixed by several glue spots 3391, thereby forming an air duct 339 between the third curvature gradient double horn body flow guide piece 333 and the fourth curvature gradient double horn body flow guide piece 334, and forming an air duct 339 between the fourth curvature gradient double horn body flow guide piece 334 and the fifth curvature gradient double horn body flow guide piece 335.

[0314] With the above design, the third curvature gradient double-horn body air guide 333 will not block the throat 310c of the fourth curvature gradient double-horn body air guide 334, and the third curvature gradient double-horn body air guide 333 and the fourth curvature gradient double-horn body air guide 334 will not block the throat 310c of the fifth curvature gradient double-horn body air guide 335. Therefore, the fourth curvature gradient double-horn body air guide 334 and the fifth curvature gradient double-horn body air guide 335 still retain sufficient cold air guiding capabilities, which can attract cold air into their interiors, and then guide the cold air into the next-level curvature gradient double-horn body air guide 315, thereby enhancing the cold air guiding effect.

[0315] At the same time, in this embodiment, the distance between the large mouth end 310a of the third curvature gradient double horn body guide member 333 and the corresponding large mouth end 310a of the fourth curvature gradient double horn body guide member 334 exceeds one third of the length of the fourth curvature gradient double horn body guide member 334; the distance between the large mouth end 310a of the fourth curvature gradient double horn body guide member 334 and the corresponding large mouth end 310a of the fifth curvature gradient double horn body guide member 335 exceeds one third of the length of the fifth curvature gradient double horn body guide member 335.

[0316] Through the above design, it is possible to prevent the end of the third curvature gradient double-horn body guide member 333 from protruding too much from the interior of the fourth curvature gradient double-horn body guide member 334, and to prevent the end of the fourth curvature gradient double-horn body guide member 334 from protruding too much from the interior of the fifth curvature gradient double-horn body guide member 335, resulting in the cold air gathered by the curvature gradient double-horn body guide member 315 of the previous level not being easily introduced into the internal channel of the curvature gradient double-horn body guide member 315 of the next level.

[0317] Of course, after testing, only the distance between the large mouth end 310a of the third curvature gradient double-horn body guide member 333 and the corresponding large mouth end 310a of the fourth curvature gradient double-horn body guide member 334 is increased to exceed one quarter of the length of the fourth curvature gradient double-horn body guide member 334; only the distance between the large mouth end 310a of the fourth curvature gradient double-horn body guide member 334 and the corresponding large mouth end 310a of the fifth curvature gradient double-horn body guide member 335 is increased to exceed one quarter of the length of the fifth curvature gradient double-horn body guide member 335, which also does not affect the introduction of cold air into the internal channel of the curvature gradient double-horn body guide member 315 of the next level.

[0318] It should be noted that, in the present embodiment, the through holes of the third curvature gradient double horn body flow guide 333, the fourth curvature gradient double horn body flow guide 334 and the fifth curvature gradient double horn body flow guide 335 at the narrowest part of the channel may only partially overlap. At this time, the central axes and center points of the third curvature gradient double horn body flow guide 333, the fourth curvature gradient double horn body flow guide 334 and the fifth curvature gradient double horn body flow guide 335 do not coincide. However, as long as the nested design is met, the cold air of the user to be removed can be continuously and stably drawn out, thereby achieving a good effect of removing the cold air, and also meeting the protection effect of the present application.

[0319] Alternatively, in the nested guide assembly 330, only two double-flared guide members 315 with gradually varying curvature have completely overlapping through-holes at the narrowest part of the channel, which can also achieve the above-mentioned effect and is within the protection scope of this application.

[0320] It should be noted that in other methods, while there is only one double-horn body guide piece 315 with a gradual curvature at each level, the nested guide assembly 330 can also adopt a design of more than four levels, that is, the nested guide assembly 330 is composed of more than four double-horn body guide pieces 315 with a gradual curvature of different sizes nested. The specific number design can be adjusted accordingly according to actual needs. As for the design of the corresponding nested guide assembly 330, reference can be made to the overall design of the nested guide assembly 330 and the specific design of the two adjacent levels of gradual curvature double-horn body guide pieces 315 in the first and second embodiments. As long as the condition of "looking along the central axis direction of the double-horn body guide piece 315 of the previous level, the through holes of the double-horn body guide piece 315 of the previous level and the double-horn body guide piece 315 of the next level at the narrowest part of the channel at least partially overlap" is met, it will not be explained in detail here.

[0321] As shown in Figure 27, as the third embodiment in the embodiment of the present application, the difference from the above embodiment is that in the embodiment of the present application, the number of the curvature gradient double horn body guide pieces 315 in the next level is two. Specifically, the nested guide assembly 330 adopts a two-stage double nested guide assembly, including a first-stage curvature gradient double horn body guide piece 336 and a second-stage curvature gradient double horn body guide piece 337. The number of the first-stage curvature gradient double horn body guide piece 336 is one, and the number of the second-stage curvature gradient double horn body guide piece 337 is two; the two second-stage curvature gradient double horn body guide pieces 337 are nested side by side in the first-stage curvature gradient double horn body guide piece 336, there is no gap between the two second-stage curvature gradient double horn body guide pieces 337, and the through holes of the two second-stage curvature gradient double horn body guide pieces 337 at the narrowest part of the channel overlap with the through holes of the first-stage curvature gradient double horn body guide piece 336 at the narrowest part of the channel.

[0322] In this embodiment, two second-stage curvature gradient double-horn body flow guide pieces 337 are nested inside a first-stage curvature gradient double-horn body flow guide piece 336, and the two second-stage curvature gradient double-horn body flow guide pieces 337 are connected in series inside the channel of the first-stage curvature gradient double-horn body flow guide piece 336, and there is no gap between the two second-stage curvature gradient double-horn body flow guide pieces 337. After the cold air passes through the two second-stage curvature gradient double-horn body guide pieces 337 connected in series, the cold air will be more concentrated and more directed; moreover, since the first-stage curvature gradient double-horn body guide piece 336 is nested outside the two second-stage curvature gradient double-horn body guide pieces 337 connected in series, under the guidance of the first-stage curvature gradient double-horn body guide piece 336, the cold air will not be retained between the two second-stage curvature gradient double-horn body guide pieces 337 connected in series. The cold air can pass through the nested guide assembly 330 in a more concentrated manner, further improving the stability of the cold air outflow while ensuring that the cold air can smoothly pass through the second-stage curvature gradient double-horn body guide piece 337.

[0323] Moreover, if too many second-stage curvature gradient double-flare body guide pieces 337 are nested inside the first-stage curvature gradient double-flare body guide piece 336, the second-stage curvature gradient double-flare body guide piece 337 will protrude too much from the throat 310c of the first-stage curvature gradient double-flare body guide piece 336, that is, the large mouth end 310a of the second-stage curvature gradient double-flare body guide piece 337 located at the edge will be closer to the large mouth end 310a of the first-stage curvature gradient double-flare body guide piece 336, resulting in the cold air being gathered by the large mouth end 310a of the first-stage curvature gradient double-flare body guide piece 336, and not being easily guided into the interior of the second-stage curvature gradient double-flare body guide piece 337. Therefore, only two second-stage curvature gradient double-flare body flow guide pieces 337 are nested inside the first-stage curvature gradient double-flare body flow guide piece 336, so that the large mouth end 310a of the edge of the second-stage curvature gradient double-flare body flow guide piece 337 is far away from the large mouth end 310a of the first-stage curvature gradient double-flare body flow guide piece 336, and the cold air is more easily guided into the channel of the second-stage curvature gradient double-flare body flow guide piece 337.

[0324] In this embodiment, the two second-stage, gradually-varying, dual-flared flow guides 337 have the same size and shape, preventing sudden changes in the flow of cold air within the same dual-flared flow guide 315. Furthermore, the edges of the opposing large openings 310a of the two second-stage, gradually-varying, dual-flared flow guides 337 are bonded together to prevent cold air from escaping between the two second-stage, gradually-varying, dual-flared flow guides 337.

[0325] Furthermore, the two second-stage curvature gradient double-flare body guide pieces 337 are both proportionally scaled parts of the first-stage curvature gradient double-flare body guide piece 336, so that the two-stage curvature gradient double-flare body guide pieces 315 have good consistency due to the same contour shape, and the transition from the inner wall curve of the first-stage curvature gradient double-flare body guide piece 336 to the inner wall curve of the second-stage curvature gradient double-flare body guide piece 337 is more natural, and the cold air guiding process is smoother.

[0326] In the nested guide assembly 330 provided in this embodiment, the central axes of the three double-horn guide members 315 with gradual curvature are all coincident, so that the convergence direction of the cold air of all the double-horn guide members 315 with gradual curvature tends to be the same straight line, so that the cold air is guided out along the same straight line, so that the cold air guidance is stable and not easily disturbed by the external environment.

[0327] At the same time, in the first-stage curvature gradient double-flare body guide piece 336, the fitting position between the two second-stage curvature gradient double-flare body guide pieces 337 is located at the center point of the first-stage curvature gradient double-flare body guide piece 336, that is, the narrowest part of the throat 310c of the first-stage curvature gradient double-flare body guide piece 336, but the two second-stage curvature gradient double-flare body guide pieces 337 do not block the channel of the first-stage curvature gradient double-flare body guide piece 336, so that there is an airway 339 between the first-stage curvature gradient double-flare body guide piece 336 and the second-stage curvature gradient double-flare body guide piece 337.

[0328] Among them, the width of the air duct 339, that is, the distance between the first-stage curvature gradient double-horn body guide 336 and the second-stage curvature gradient double-horn body guide 337 is 0.5-2mm. Through experimental tests, the width of the air duct 339 in this width range can enable the first-stage curvature gradient double-horn body guide 336 to still retain sufficient cold air guiding ability, and can attract cold air into its interior, and then guide the cold air into the second-stage curvature gradient double-horn body guide 337, thereby enhancing the cold air guiding effect.

[0329] As a method for forming an airway 339, as shown in Figure 28, the area of ​​the large opening 310a of the second-stage, gradually changing curvature, double-flared flow guide 337 is smaller than the area of ​​the smallest throat 310c of the first-stage, gradually changing curvature, double-flared flow guide 336, i.e., the size of the through-hole at the smallest point of the passage. The two second-stage, gradually changing curvature, double-flared flow guides 337 are fixed to the interior of the first-stage, gradually changing curvature, double-flared flow guide 336 by glue at their joints. Three specific glue locations 3391 are sufficient, with the angle between adjacent glue locations 3391 being 120°. This ensures stability while also reducing the area of ​​the airway 339 between two adjacent gradually changing curvature, double-flared flow guides 315. Depending on the actual situation, the number of glue locations can be increased or decreased, or even the fixing method can be modified, such as by using clamping or welding.

[0330] As another method of forming air passage 339, as shown in Figures 29 and 30, multiple guiding warps 313 and multiple guiding wefts 314 are provided on the inner wall of a first-stage, gradually curvatured, double-flared flow guide 336. The multiple guiding warps 313 extend from one opening of the passage toward the other opening of the passage, while the multiple guiding wefts 314 surround the central axis of the passage and are spaced apart along the central axis. Furthermore, both the guiding warps 313 and guiding wefts 314 are grooved, forming air passage 339. The addition of the guiding warps 313 and guiding wefts 314 makes the guidance of cold air more directional, resulting in a better guiding effect.

[0331] In this embodiment, the edge of the wide-mouthed end 310a of the second-stage, gradually-varying-curvature, double-flared-body flow guide 337 can abut the inner wall of the first-stage, gradually-varying-curvature, double-flared-body flow guide 336. Due to the presence of the guiding warp threads 313 and weft threads 314, the third-stage, gradually-varying-curvature, double-flared-body flow guide 338 cannot block the corresponding internal passage of the second-stage, gradually-varying-curvature, double-flared-body flow guide 337, and the second-stage, gradually-varying-curvature, double-flared-body flow guide 337 cannot block the internal passage of the first-stage, gradually-varying-curvature, double-flared-body flow guide 336. The guiding warp threads 313 and weft threads 314 form an airway 339, allowing cold air to pass through them. Furthermore, the guiding warp threads 313 and weft threads 314 limit and guide the glue during the dispensing process, preventing it from converging and blocking the gaps.

[0332] In addition, as shown in Figure 31, the distance a between the outer ends of the two second-stage curvature gradient double-flare body flow guides 337, that is, the large-mouth end 310a away from the center point of the first-stage curvature gradient double-flare body flow guide 336, and the corresponding large-mouth end 310a of the first-stage curvature gradient double-flare body flow guide 336, exceeds one-quarter of the length L of the first-stage curvature gradient double-flare body flow guide 336.

[0333] The above design avoids the problem of the end of the second-stage, gradually-varying-curvature, double-flared-body flow guide 337 protruding too far, which could hinder the flow of cold air gathered by the first-stage, gradually-varying-curvature, double-flared-body flow guide 336 into the internal passage of the second-stage, gradually-varying-curvature, double-flared-body flow guide 337. Furthermore, the distance between the outer end of the second-stage, gradually-varying-curvature, double-flared-body flow guide 337 and the corresponding wide-mouth end 310a of the first-stage, gradually-varying-curvature, double-flared-body flow guide 336 can be increased to exceed one-third of the length of the first-stage, gradually-varying-curvature, double-flared-body flow guide 336, as needed.

[0334] As shown in FIG32 , the fourth embodiment provided as an example of the present application differs from the third embodiment in that the nested guide assembly 330 in this embodiment adopts a three-level nesting arrangement, forming a three-level double-nested guide assembly. Specifically, the nested guide assembly 330 includes a first-level, gradually changing, double-flared guide member 336, a second-level, gradually changing, double-flared guide member 337, and a third-level, gradually changing, double-flared guide member 338. There is one first-level, gradually changing, double-flared guide member 336, two second-level, gradually changing, double-flared guide members 337, and four third-level, gradually changing, double-flared guide members 338. Two third-level, gradually changing, double-flared guide members 338 are nested side by side within one second-level, gradually changing, double-flared guide member 337, and two second-level, gradually changing, double-flared guide members 337 are nested side by side within the first-level, gradually changing, double-flared guide member 336.

[0335] Moreover, the edges of the large mouth ends 310a between the two third-stage curvature gradient double-horn body guide pieces 338 located inside the same second-stage curvature gradient double-horn body guide piece 337 are fitted together without a gap, and the edges of the large mouth ends 310a between the two second-stage curvature gradient double-horn body guide pieces 337 located inside the first-stage curvature gradient double-horn body guide piece 336 are fitted together without a gap.

[0336] Since the more nested layers within the nested guide assembly 330, the better the guiding effect, but this results in a larger volume and higher cost for the nested guide assembly 330, a three-layer nested design is more suitable: a first-stage, gradually-varying-curvature, double-flared guide 336, a second-stage, gradually-varying-curvature, double-flared guide 337, and a third-stage, gradually-varying-curvature, double-flared guide 338. Therefore, the nested guide assembly 330 in this embodiment preferably adopts a three-layer nested design. For ease of explanation, this embodiment will be described using this three-layer nested design.

[0337] Similarly, in this embodiment, the size and shape of the double-horn body guide 315 with a same level of curvature gradient are the same, so as to avoid the problem of sudden changes when the cold air flows inside the double-horn body guide 315 with a same level of curvature gradient.

[0338] Similar to the previous embodiment, in the nested guide assembly 330, the central axes of all the curvature gradient double-horn body guide members 315 are coincident, the third-stage curvature gradient double-horn body guide member 338 is a proportional scaled part of the second-stage curvature gradient double-horn body guide member 337, and the second-stage curvature gradient double-horn body guide member 337 is a proportional scaled part of the first-stage curvature gradient double-horn body guide member 336.

[0339] In the first-stage curvature gradient double-flare body guide piece 336, the fitting position between the two second-stage curvature gradient double-flare body guide pieces 337 is located at the center point of the first-stage curvature gradient double-flare body guide piece 336, that is, the narrowest part of the throat 310c of the first-stage curvature gradient double-flare body guide piece 336, but the two second-stage curvature gradient double-flare body guide pieces 337 do not block the passage of the first-stage curvature gradient double-flare body guide piece 336, so that there is an airway 339 between the first-stage curvature gradient double-flare body guide piece 336 and the second-stage curvature gradient double-flare body guide piece 337. Similarly, in the second-stage curvature gradient double-flare body guide piece 337, the fitting position between the two third-stage curvature gradient double-flare body guide pieces 338 is located at the center point of the corresponding second-stage curvature gradient double-flare body guide piece 337, that is, the narrowest part of the throat 310c of the second-stage curvature gradient double-flare body guide piece 337. The two third-stage curvature gradient double-flare body guide pieces 315 do not block the channel of the corresponding second-stage curvature gradient double-flare body guide piece 337, so that there is an airway 339 between the second-stage curvature gradient double-flare body guide piece 337 and the corresponding third-stage curvature gradient double-flare body guide piece 338.

[0340] For the design of the airway 339 , please refer to the description in the third embodiment for details, and no further details will be given here.

[0341] In this embodiment, in each second-stage double-flared-body flow guide member 337 with a gradual curvature, the distance between the outer ends of the two third-stage double-flared-body flow guide members 338, i.e., the wide-mouthed ends 310a away from the center point of the second-stage double-flared-body flow guide member 337, and the corresponding wide-mouthed ends 310a of the second-stage double-flared-body flow guide member 337, exceeds one-quarter the length of the second-stage double-flared-body flow guide member 337. Similarly, the distance between the outer ends of the two second-stage double-flared-body flow guide members 337, i.e., the wide-mouthed ends 310a away from the center point of the first-stage double-flared-body flow guide member 336, and the corresponding wide-mouthed ends 310a of the first-stage double-flared-body flow guide member 336, exceeds one-quarter the length of the first-stage double-flared-body flow guide member 336.

[0342] The above design can avoid the problem of the end of the next-stage gradually-varying-curvature dual-flared-body air guide 315 being too protruding, which would prevent the cold air gathered by the previous-stage gradually-varying-curvature dual-flared-body air guide 315 from being easily guided into the internal passage of the next-stage gradually-varying-curvature dual-flared-body air guide 315. Furthermore, as needed, the distance between the outer end of the third-stage gradually-varying-curvature dual-flared-body air guide 338 and the corresponding wide-mouth end 310a of the second-stage gradually-varying-curvature dual-flared-body air guide 337 can be set to exceed one-third of the length of the second-stage gradually-varying-curvature dual-flared-body air guide 337; and the distance between the outer end of the second-stage gradually-varying-curvature dual-flared-body air guide 337 and the corresponding wide-mouth end 310a of the first-stage gradually-varying-curvature dual-flared-body air guide 336 can be set to exceed one-third of the length of the first-stage gradually-varying-curvature dual-flared-body air guide 336.

[0343] It should be noted that in the embodiment of the present application, the nested guide assembly 330 can also adopt a design of more than four levels, that is, the nested guide assembly 330 is formed by nesting more than four levels of curvature gradient double-horn body guide pieces 315, and each upper-level curvature gradient double-horn body guide piece 315 can be nested with more than three lower-level curvature gradient double-horn body guide pieces 315. The specific selection is made according to needs. The specific design refers to the specific design of the nested guide assembly 330 as a whole and the adjacent two-level curvature gradient double-horn body guide pieces 315 in the embodiment of the present application, and no further details will be given here.

[0344] Example 4: Flow deflector

[0345] As a fourth embodiment of the present application, the flow guide module 300 is provided as a flow guide device 340 . The flow guide device 340 includes at least one nested flow guide component 330 in the third embodiment.

[0346] As shown in Figure 33, as a first embodiment of the present application, the deflector 340 is composed of two nested deflector assemblies 330 and an independent, gradually varying curvature, dual-flare deflector 315. The gradually varying curvature, dual-flare deflector 315 is positioned between the two nested deflector assemblies 330. In this embodiment, each nested deflector assemblies 330 provides at least two levels of attraction, sufficient to allow more concentrated cold air to pass through the throat 310c of the next-level gradually varying curvature, dual-flare deflector 315. The combination of the two nested deflector assemblies 330 can better eliminate the root cause of cold air. Combined with an independent, gradually varying curvature, dual-flare deflector 315, the two nested deflector assemblies 330 and the independent, gradually varying curvature, dual-flare deflector 315 are connected in series to form the deflector 340. This allows the cold air to be converged multiple times, ultimately reducing the amount of cold air that escapes, strengthening the connection with the energy source 600, and improving stability, thereby effectively ensuring the cold air removal effect.

[0347] Furthermore, the size of the double-flared flow guide piece 315 with a gradually varying curvature is smaller than the size of the outermost double-flared flow guide piece 315 with a gradually varying curvature in the two nested flow guide assemblies 330 .

[0348] In the deflector 340, the larger nested deflector assembly 330 is placed on the outside, and the smaller curvature gradient dual-horn deflector 315 is placed on the inside. This positions the larger curvature gradient dual-horn deflector 315 opposite the human body and the energy source 600. Therefore, the nested deflector assembly 330 facing the human body can gather cold air over a wider range, while the nested deflector assembly 330 facing the energy source 600 can establish contact between the cold air and the energy source 600 over a wider range, allowing for full contact between the cold air and the energy source 600, thereby making the connection between the two more stable. The smaller curvature gradient dual-horn deflector 315 located inside the deflector 340 can further gather and concentrate the cold air passing through, making it less likely to be interrupted during its movement within the deflector 340.

[0349] In this embodiment, the central axes of the two nested flow guide assemblies 330 and the gradually-varying-curvature dual-flared flow guide 315 coincide, and the two nested flow guide assemblies 330 are identical in size and shape. The gradually-varying-curvature dual-flared flow guide 315 located between the two nested flow guide assemblies 330 is a scaled-down version of the outermost gradually-varying-curvature dual-flared flow guide 315 in the nested flow guide assemblies 330. Furthermore, the gradually-varying-curvature dual-flared flow guide 315 is equidistant from the two nested flow guide assemblies 330. Of course, the above-described specific design can also be adjusted based on actual conditions.

[0350] As shown in Figure 34, as the second embodiment in the embodiment of the present application, the deflector 340 is composed of three nested deflector components 330, namely the first nested deflector component 330a, the second nested deflector component 330b and the third nested deflector component 330c, wherein the second nested deflector component 330b is located between the first nested deflector component 330a and the third nested deflector component 330c, the sizes of the first nested deflector component 330a and the third nested deflector component 330c are equal, and the size of the second nested deflector component 330b is smaller than the size of the first nested deflector component 330a.

[0351] In this embodiment, the combination of the three nested guide components 330 can bring greater attraction to the cold air, so that the cold air is sucked out more thoroughly, avoiding the problem of recurring symptoms.

[0352] In this embodiment, the central axes of the three nested guide components 330 coincide, and the distance between the second nested guide component 330b and the first nested guide component 330a is equal to the distance between the second nested guide component 330b and the third nested guide component 330c, so as to ensure the stability of the cold air in the deflector 340.

[0353] It should be noted that, as shown in FIG. 35 and FIG. 36 , the deflector 340 may also be composed of only one independent double-flared deflector 315 with gradually varying curvature and one nested deflector assembly 330 , or only two nested deflector assemblies 330 of the same size.

[0354] Even more, the deflector 340 can also be composed of more than four nested deflector components 330 in series, or composed of multiple independent curvature gradient double horn body deflectors 315 and multiple nested deflector components 330 in series, as long as the following conditions are met: when the deflector 340 is composed of the curvature gradient double horn body deflector 315 and the nested deflector component 330, the deflector 340 includes at least one nested deflector component 330 and at least one independent curvature gradient double horn body deflector 315, the curvature gradient double horn The body guide piece 315 and the nested guide assembly 330 are arranged in parallel in sequence, that is, the curvature gradient double-horn body guide piece 315 and the nested guide assembly 330 are connected in series. Looking from the side of the guide 340 (the large mouth end 310a of the curvature gradient double-horn body guide piece 315), the large mouth end 310a of the independent curvature gradient double-horn body guide piece 315 at least partially overlaps with the large mouth end 310a of the outermost curvature gradient double-horn body guide piece 315 in the nested guide assembly 330. When the deflector 340 is composed of nested deflector components 330, the deflector 340 includes at least two nested deflector components 330, and the nested deflector components 330 are arranged in parallel in sequence, that is, these nested deflector components 330 are arranged in series. When viewed from the side of the deflector 340, the large mouth ends 310a of the outermost double-flared deflector parts 315 with gradually changing curvature in two adjacent nested deflector components 330 at least partially overlap.

[0355] The specific design is selected according to actual needs and is not limited here.

[0356] In an embodiment of the present application, by arranging two or more nested guide assemblies 330 in parallel, or arranging a nested guide assembly 330 and a curvature gradient double-horn guide piece 315 in parallel, the cold air can be converged twice or more, and the cold air has a stronger tendency to move toward the energy source 600 along the axial direction, making it less likely for the cold air to attenuate during movement. Compared with a single nested guide assembly 330, the cold air after the series design in this solution is converged multiple times, and the final amount of cold air that is scattered is less, and the connection between the cold air and the energy source 600 is stronger, and the stability is better. During the movement process, the secondary convergence of the latter-stage nested guide assembly 330 or the curvature gradient double-horn guide piece 315 has a stabilizing effect on the former-stage nested guide assembly 330 or the curvature gradient double-horn guide piece 315. The former-stage nested guide assembly 330 or the curvature gradient double-horn guide piece 315 is less affected by changes in the external environment and is more stable during movement. In summary, the use of the deflector 340 can enhance the guiding effect of the cold air, while stabilizing the connection between the cold air and the energy source 600 during the movement, thereby improving the effect of removing the cold air.

[0357] Example 5: Cold-dispelling device

[0358] In an embodiment of the present application, as shown in Figure 37, as an implementation method of the mobile component 100, the mobile component 100 adopts a four-wheeled cart solution, and the mobile component 100 specifically includes a frame 111, wheels 112, a motor 113, a conveyor belt 114, a rotating wheel 115, a lifting gallows 116 and an installation platform 117.

[0359] Wheels 112 are fixed to the vehicle frame 111, and motors 113 drive wheels 112 via transmission belts 114. A control module 400, mounted on the vehicle frame 111, controls the direction, speed, and duration of the motor 113 and is composed of discrete electrical components. The bottom end of the lifting gallows 116 is fixed to the vehicle frame 111, with the top end fixed to the mounting platform 117. A rotating wheel 115 is fixed to the front end of the vehicle frame 111 and connected to the bottom end of the lifting gallows 116 via a screw rod, controlling the ascent and descent of the mounting platform 117. The energy source fixing structure 200 and the diversion bracket 500 are fixed to the mounting platform 117. The energy source 600 is fixed to the energy source fixing structure 200, and the diversion module 300 (e.g., the curvature gradient double-flared diversion member 315) is fixed to the diversion bracket 500.

[0360] In this embodiment, the energy source 600 can be an moxa stick 610, which can be moved on the ground by controlling a four-wheeled cart to avoid manual transportation; moreover, the energy source 600 and the diversion module 300 can be controlled to move up and down through the lifting gallows 116, so that the diversion module 300 can be aligned with the treatment parts at different heights on the user's body, thereby improving the applicability of the cold-removing equipment 10.

[0361] As shown in Figure 38, as another embodiment of the mobile component 100, the mobile component 100 adopts a ground rail 121 solution. The mobile component 100 specifically includes a ground rail 121, a mobile chassis 122, a motor (not shown in the figure), a tripod 123 and an installation platform 117.

[0362] A ground track 121 is laid on the ground, and a mobile chassis 122 is placed on the ground track 121. The mobile chassis 122 is driven by a motor to move on the ground track 121. A control module 400 is installed on the mobile chassis 122 to control the operation of the motor. A liftable tripod 123 is installed on the mobile chassis 122, and a mounting platform 117 is mounted on the liftable tripod 123. The mounting platform 117 is used to fix the energy source fixed structure 200 and the diversion bracket 500. The energy source 600 is fixed to the energy source fixed structure 200, and the diversion module 300 (for example, the curvature gradient double horn diversion member 315) is fixed to the diversion bracket 500.

[0363] In this embodiment, since the ground rail 121 has high requirements for slow speed and anti-shake, after the moving component 100 adopts the ground rail 121 solution, the energy source 600 and the diversion module 300 can be very stable during the movement process, and can also maintain stable and slow movement, which is beneficial to ensure the continuous and stable connection between the energy source 600 and the cold air during the movement.

[0364] As shown in FIG39 , as another embodiment of the mobile component 100 , the mobile component 100 adopts a mobile three-wheeled frame 111 solution, and the mobile component 100 specifically includes a bracket 131 , a trolley 132 and a cross bar 133 .

[0365] The trolley 132 utilizes a tricycle chassis, and the support 131 is a liftable tripod 123. The tricycle chassis moves directly on the ground. A crossbar 133 is located above the liftable tripod 123, and includes three clamps 134. The clamps 134 are fixed to the crossbar 133 in an adjustable position. The first clamp 134 is used to secure the crossbar 133 to the liftable tripod 123. The second clamp 134 is used to secure the energy source fixing structure 200, and the third clamp 134 is used to secure the diversion bracket 500. The energy source 600 is secured to the energy source fixing structure 200, and the diversion module 300 (e.g., the curvature gradient dual-flare diversion member 315) is secured to the diversion bracket 500.

[0366] The tricycle chassis includes a main drive wheel assembly and two driven wheel assemblies. The driving wheel in the main drive wheel assembly is driven by a stepper motor. The control module 400 and lithium battery are integrated into the main drive wheel assembly. The crossbar 133 is located directly above the main drive wheel assembly and is arranged in the direction of travel of the main drive wheel assembly. The moxa cone holder 210 and the diversion bracket 500 are fixed to the end away from the main drive wheel assembly.

[0367] By adopting the technical solution of this embodiment, mobile assembly 100 takes up little space, making it easy to carry and store. Furthermore, no additional track is required, significantly reducing costs. Although the floor is not as flat as the floor rail 121, cold-removing equipment is generally used indoors, where the ground is relatively flat, and the stability during movement is generally sufficient.

[0368] As shown in Figure 40, as another embodiment of the moving component 100, the moving component 100 adopts a sliding rod 1411 solution. The moving component 100 specifically includes a sliding rod component 141, a support frame 142, an installation platform 117, a belt 1414, a front shell 143 and a rear shell 146.

[0369] In this embodiment, the sliding rod assembly 141 includes two sliding rods 1411 and two sliding rod 1411 fixing blocks, wherein the two sliding rod 1411 fixing blocks are respectively a first sliding rod fixing block 1412 and a second sliding rod fixing block 1413; both ends of the sliding rod 1411 are fixed to the support frame 142 by the first sliding rod fixing block 1412 and the second sliding rod fixing block 1413 respectively;

[0370] The first slide bar fixing block 1412 is located below the front housing 143, and the second slide bar fixing block 1413 is located below the rear housing 146. A support frame 142 is used below each of the two slide bar 1411 fixing blocks to suspend the two slide bars 1411 in the air to form a track. The mounting platform 117 is set on the track. The energy source fixing structure 200 and the diversion module 300 are both fixed to the mounting platform 117 and move along the track with the mounting platform 117.

[0371] A driven pulley of a belt 1414 is provided in the first slide bar fixing block 1412; a driving pulley of a belt 1414 is provided in the second slide bar fixing block 1413; the belt 1414 is located between the two slide bars 1411, and is sleeved on the driven pulley of the belt 1414 and the driving pulley of the belt 1414; both ends of the belt 1414 are fixed on the mounting platform 117 to form a closed loop structure; the closed loop structure formed by rotating the belt 1414 drives the mounting platform 117 to move on the track.

[0372] The technical solution of this embodiment does not occupy ground space and is lighter than the ground rail 121 method. Through track positioning, the movement trajectory of moxa products and guide members can be accurately defined, without the risk of interference with other objects. After resetting, no manual adjustment is required, making it easy to use.

[0373] As shown in Figures 40, 41 and 42, as a specific embodiment, the front shell 143 is located at the end of the diversion module 300 away from the energy source 600, is fixed to one end of the slide assembly 141, and is facing the diversion module 300. An initial travel switch 144, a counter and a start button 145 are provided in the front shell 143. The initial travel switch 144 is located on the side of the front shell 143 facing the installation platform 117, and is used to detect the initial position of the installation platform 117.

[0374] The rear shell 146 is located at one end of the energy source 600 away from the diversion module 300 and is fixed to the other end of the slide rod assembly 141; a control module (not shown in the figure), a motor (not shown in the figure), an end travel switch 147, a billing module, an antenna 148 and a power supply are provided in the rear shell 146, wherein the control module is a logic circuit board structure.

[0375] The power supply can be an external power adapter, which can directly convert the mains electricity into the working voltage required by the mobile component 100, and then connect it to the power input terminal of the billing module through a wire. The signal receiving end of the billing module is connected to the antenna 148; the antenna 148 is placed on the upper surface of the rear shell 146 to facilitate the reception of external wireless signals. The power output terminal of the billing module is connected to the power input terminal of the control module 400; the control output terminal of the control module 400 is connected to the motor; the start trigger terminal of the control module 400 is connected to the start button 145; the position detection port of the control module 400 is respectively connected to the output terminals of the initial travel switch 144 and the end travel switch 147, and the end travel switch 147 is located on the side of the rear shell 146 facing the mounting platform 117, and is used to detect the end position of the mounting platform 117. A QR code recording the unique identity information of the mobile component 100 is affixed to the rear shell 146.

[0376] The control module 400 is used to control the running speed, running time, and running direction of the motor. These conditions can be set in the control module 400. The rotating shaft of the motor cooperates with the driving pulley of the belt 1414. The transmission speed, time, and direction of the belt 1414 are controlled by the motor, thereby controlling the speed, time, and direction of the installation platform 117 on the track. Different physical therapy methods can be achieved for different subjects, different parts, and different symptoms, making the physical therapy effect more targeted. Specifically, when the rotating shaft of the control motor is rotated in one direction, the belt 1414 can be controlled to move the installation platform 117 in a direction closer to the front housing 143; when the rotating shaft of the control motor is rotated in the other direction, the belt 1414 can be controlled to move the installation platform 117 in a direction away from the front housing 143.

[0377] Before starting, the mounting platform 117 is located at the initial position, and the front end surface of the protective shell 149 contacts the moving contact of the initial travel switch 144 .

[0378] During startup, the user scans the corresponding QR code with a mobile phone and pays the corresponding fee. The remote control terminal then issues a startup instruction. After the billing module receives the startup instruction through antenna 148, it turns on the power supply and issues a voice reminder to notify the user that the therapy can be performed.

[0379] After the user adjusts the position, he presses the start button 145 . After receiving the signal sent by the start button 145 , the start trigger end of the control module 400 controls the motor to run, driving the installation platform 117 to move away from the user.

[0380] When the tail of the installation platform 117 touches the moving contact of the end travel switch 147, the position detection port of the control module 400 receives the signal of the end travel switch 147 and controls the motor to stop running; after stopping for more than or equal to 5 seconds, the control module 400 controls the motor to run in reverse, allowing the installation platform 117 to move to the initial position.

[0381] When the front end of protective shell 149 touches the moving contact of initial travel switch 144, the position detection port of control module 400 receives a signal from end travel switch 147, controlling the motor to stop, and mounting platform 117 is reset. The billing module disconnects power to control module 400 after a preset time. At this point, pressing start button 145 is ineffective, requiring the user to scan the QR code again to pay before restarting.

[0382] The counter is coupled to the end travel switch 147, and when the moving contact of the end travel switch 147 is closed, the value of the counter is increased by 1. With the counter, it is convenient for local management personnel to intuitively count the number of times the cold-dispelling device 10 is used.

[0383] The essential oil bottle 220 containing the essential oil 620 can be directly placed on the mounting platform 117, and the bottle cap 222 of the essential oil bottle 220 can be opened when in use; or for convenience, the essential oil bottle 220 can be designed as an automated structure that can automatically open and close the cap.

[0384] It should be noted that in the mobile assembly 100 of the embodiment of the present application, the front housing 143 may not have a counter, and the initial travel switch 144 may be replaced with other infrared sensors, acoustic sensors, or other structures to detect the position of the mounting platform 117, while the start button 145 may be set in the rear housing 146 or other locations. In addition, other functional modules may be added to the front housing 143 as needed. As for the rear housing 146, the billing module and antenna 148 may also be omitted, and the end travel switch 147 may be replaced with other infrared sensors, acoustic sensors, or other structures to detect the position of the mounting platform 117. The control module 400, motor, and power supply may be set in the front housing 143 or other locations. In addition, other functional modules may also be added to the rear housing 1461 as needed to meet the various usage requirements of customers, and no further limitations are given.

[0385] By adopting the technical solution of the embodiment of the present application, the cold-dispelling device 10 does not occupy ground space and is relatively lightweight. Through track positioning, the movement trajectory of the energy source 600 and the diversion module 300 can be precisely defined, eliminating the risk of interference with other objects. After resetting, no manual adjustment is required, making it easy to use.

[0386] As shown in Figure 43, the embodiment of the present application also provides an energy source fixing structure 200, which is a moxa stick fixing seat 210. The moxa stick fixing seat 210 is detachably connected to the moving component 100; the moxa stick fixing seat 210 is used to fix the moxa stick 610, and at this time the energy source 600 is the moxa stick 610.

[0387] The cross-section of the moxa stick 610 can be square, circular, or polygonal. Taking the example of the diversion module 300 employing the double-flared diversion member 315 with a gradually varying curvature, when the moxa stick 610 is fixed to the mobile assembly 100, the cross-section (combustion surface) of the moxa stick 610 is directly aligned with the channel in the double-flared diversion member 315 with a gradually varying curvature. At this point, the horizontal projection of the moxa stick 610 overlaps with the horizontal projection of the end of the channel in the double-flared diversion member 315 with a gradually varying curvature. This allows the smoke generated by the burning moxa stick 610 to easily establish a stable connection with the cold air within the range covered by the end of the channel in the double-flared diversion member 315 with a gradually varying curvature.

[0388] Since the burning time of the moxa stick 610 cannot be precisely controlled, it is not possible to ensure that the moxa stick 610 is burned out exactly after use; therefore, the moxa stick 610 is generally left longer to ensure that the burning time of the moxa stick 610 exceeds the moving time of the moxa stick 610. After the moxa stick 610 is moved, if the moxa stick 610 is still burning, it will cause material waste if the moxa stick 610 is extinguished. If the moxa stick 610 is left on the device, it will increase the use time of the device, and other users will have to wait longer, which will reduce the efficiency of the device.

[0389] The inventors discovered that after the moxa stick 610 stops moving, the cold air still maintains contact with the human body, and continued use for a period of time can help improve the therapeutic effect. Further research has found that after the moxa stick 610 stops moving and remains for a period of time, the cold air and the moxa stick 610 can establish a natural and stable connection. In this case, the cold air and the moxa stick 610 can directly connect without the need for the gradually changing curvature double-flared body guide 315, achieving better results than using the gradually changing curvature double-flared body guide 315.

[0390] Therefore, the fixed structure of the moxa stick 610 is made into a structure that can be easily disassembled. After the moxa stick 610 stops moving, it stays for a period of time and then the moxa stick 610 is removed. In this way, the cold air and the human body can bypass the curvature gradient double horn body guide 315 and directly establish a stable connection.

[0391] Specifically, the energy source fixing structure 200 includes a tray 211 and a support platform 212. The tray 211 is detachably connected to the mobile component 100. The support platform 212 is arranged on the tray 211, and the orthographic projection of the tray 211 on the ground covers the orthographic projection of the support platform 212 on the ground; a fixing groove 213 is provided on the support platform 212, and the opening of the fixing groove 213 faces the moxa stick 610, and the opening area of ​​the fixing groove 213 is larger than the bottom area of ​​the fixing groove 213, and the moxa stick 610 is arranged in the fixing groove 213.

[0392] Regardless of whether the moxa stick fixing seat 210 is disassembled or not, the moxa stick 610 and the support platform 212 are above the tray 211, preventing the ash produced by the burning moxa stick 610 from falling on the ground or equipment; moreover, since the moxa stick 610 is supported and fixed by the fixing groove 213 in the support platform 212, even if the moxa stick 610 collapses during the burning process, it will gather at the bottom of the fixing groove 213 and will not disperse. In this way, when the tray 211 is moved, the burning moxa can be reduced from falling and injuring the user, making it safer to use; the fixing groove 213 is larger at the top and smaller at the bottom, so that after the moxa stick 610 collapses during burning, the burning part will be squeezed to the middle, preventing the moxa stick 610 from tilting, so that the burning surface is always facing the trumpet mouth.

[0393] The fixing groove 213 is preferably a V-shaped groove, which is located in the middle of the tray 211. The moxa stick 610 is fixed on the V-shaped groove, and the burning surface of the moxa stick 610 faces one end of the channel in the double-horn flow guide 315 with a gradually changing curvature.

[0394] Tray 211 can be constructed from a stainless steel disc, and support platform 212 is welded directly to tray 211. This eliminates the risk of support platform 212 falling off or being lost. Furthermore, ash from the burning moxa stick 610 does not enter the contact surface between support platform 212 and tray 211, making it difficult to clean. Once tray 211 and support platform 212 are designed, moxa stick 610 naturally aligns with the small opening 310b of the guide member, eliminating the need for manual alignment and facilitating operation.

[0395] Furthermore, a mesh cover (not shown) may be added above the tray 211 to buckle the moxa sticks 610 onto the tray 211 through the mesh cover to prevent people from touching the moxa sticks 610 and improve safety.

[0396] Moreover, a protrusion is welded on the tray 211 corresponding to the notch of the mesh cover. The protrusion cooperates with the notch of the mesh cover to limit the mesh cover and prevent the mesh cover from sliding in the tray 211.

[0397] It should be noted that when the energy source 600 uses moxa sticks 610, in order to improve the effect of removing cold air, this embodiment makes corresponding adjustments to the size of the diversion module 300 and the design of the control module 400, so that the therapeutic effect of the cold air removal device 10 is better.

[0398] Taking the example of the flow guide module 300 employing a curved dual-horn flow guide 310, the diameters of the large openings 310a of the first horn 311 and the large openings 310a of the second horn 312 range from 150mm to 270mm. When moxa products are burned, the yang energy rapidly dissipates with the heat. Therefore, the large opening 310a of the first horn 311 needs to be larger to contain the cold air, otherwise it will not be easily connected to the moxa product after exiting the guide. It has been verified that the maximum cross-sectional diameter of the large opening 310a of the first horn 311 is within the range of 150mm to 270mm, which can basically cover the range of the yang energy diffusion when the moxa product is burned.

[0399] Secondly, the diameters of the small-mouthed end 310b of the first speaker 311 and the small-mouthed end 310b of the second speaker 312 are both between 15mm and 28mm. The ratio between the large-mouthed end 310a and the small-mouthed end 310b of the first speaker 311 should be within an appropriate range. If the ratio is too large, i.e., the minimum cross-sectional diameter of the small-mouthed end 310b is too small, cold air will easily be trapped at the small-mouthed end 310b, hindering its connection with the moxa product. If the ratio is too small, the minimum cross-sectional diameter of the small-mouthed end 310b will be too large, hindering the extraction of deep-seated cold air. It has been verified that a minimum cross-sectional diameter of the small-mouthed end 310b within the range of 15mm to 28mm ensures a smooth cold air guidance process and facilitates the extraction of deep-seated cold air.

[0400] Furthermore, the distance between the wide-mouthed end 310a of the first speaker 311 and the wide-mouthed end 310a of the second speaker 312 is 80mm-150mm. The distance between the two ends of the deflector should be appropriate. If the distance is too short, there will be insufficient guiding space, resulting in poor cold air guidance. If the distance is too long, cold air will easily stagnate within the deflector, hindering its continued removal. It has been verified that within the range of 80mm-150mm, the deflector has a better guiding effect and less cold air remains within the gradually curving dual-speaker deflector 315.

[0401] The distance between the moxa product and the first horn 311 is 10-30 cm. If the moxa product is too close to the gradually curving double-horn flow guide 315, more heat will be transferred to the small opening 310b, suppressing the cold air and hindering its expulsion. If the distance is too far, the cold air will have difficulty connecting with the moxa product. It has been proven that a distance of 10-15 cm from the gradually curving double-horn flow guide 315 is most effective.

[0402] The embodiment of the present application also provides another energy source fixing structure 200, wherein the energy source 600 is essential oil 620, and the essential oil 620 is located in the essential oil bottle 220. The energy source fixing structure 200 is the essential oil bottle 220 and related structures.

[0403] Traditional Chinese Medicine believes that essential oils share many similarities with aromatic herbs. Aromatic herbs can dredge meridians and channels, opening the orifices and penetrating the bones. The volatile aroma of these herbs directly affects the nose, mouth, skin, and meridian points, circulating through the qi and blood channels throughout the body. This aroma helps regulate the body's yin and yang balance, invigorating vital energy and resisting external pathogens. The Shennong Bencao Jing states: "Fragrance represents the righteousness of qi, and abundant righteousness dispels evil and wards off evil." Most aromatic herbs are pungent in flavor. The Huangdi Neijing states: "pungent, sweet, and bland are yang, while sour, bitter, and salty are yin." The Suwen: Storing Qi and the Way of Time states: "pungent dispersing, sour astringing, sweet soothing, bitter firming, and salty softening." Pungent herbs have both activating and dispersing properties, promoting qi and blood circulation, dispersing external pathogens, dispersing internal cold, and dispersing internal stagnation. Once an essential oil enters the body, it attracts and connects with cold qi, and its pungent and aromatic properties dissipate the cold, dispersing it from the body. Likewise, when the essential oil is away from the human body, the connection with the cold air continues, steadily and continuously expelling the cold air from the body.

[0404] Because essential oils have no open flames, smoke, or direct contact with the human body, they generally have no side effects, unless someone is allergic to essential oil 620. Therefore, essential oil 620 can replace moxa sticks as an energy source 600 to draw out the body's chill. Compared to moxa sticks, essential oil 620 enters the body through natural diffusion, creating a more uniform and natural connection with the chill, creating a more stable connection. This allows essential oil 620 to draw out more chill as it moves.

[0405] It should be noted that since the energy source 600 in the embodiment of the present application uses essential oil 620, in order to improve the effect of removing cold air, this embodiment has made corresponding adjustments to the size of the diversion module 300 and the design of the control module 400, so that the therapeutic effect of the cold-removing device 10 is better.

[0406] Specifically, taking the curved double-horn body guide 310 as an example, the diameters of the large mouth end 310a of the first horn 311 and the large mouth end 310a of the second horn 312 are 120mm-180mm, the diameters of the small mouth end 310b of the first horn 311 and the small mouth end 310b of the second horn 312 are both 11mm-18mm, and the distance between the large mouth end 310a of the first horn 311 and the large mouth end 310a of the second horn 312 is 75mm-114mm.

[0407] Because the essential oil 620 naturally evaporates and connects with the cold air, releasing it slowly, the curved double-flared flow guide 310 does not need to be large to cover the evaporation range of the essential oil 620. Therefore, compared to the previous embodiment, the curved double-flared flow guide 310 corresponding to the essential oil 620 is slightly smaller than the curved double-flared flow guide 310 corresponding to the moxa product, resulting in a corresponding reduction in the small opening 310b. It has been verified that the flow guide within this size range can cover a wide range of naturally evaporating essential oils 620.

[0408] Furthermore, the distance between the essential oil 620 and the first speaker 311 is 10-50 cm. The closer the essential oil 620 is to the curved dual-speaker flow guide 310, the easier it is for cold air to enter the curved dual-speaker flow guide 310. However, if the distance is too close, the curved dual-speaker flow guide 310 may be blocked, reducing the diversion effect. It has been verified that a distance of 10-50 cm between the essential oil 620 and the large opening 310a of the first speaker 311 provides the best cold air diversion effect.

[0409] As one embodiment, as shown in FIG44 , the essential oil bottle 220 is mounted on the mobile assembly 100. The mobile assembly 100 controls the essential oil bottle 220 to move away from the user to be treated for cold. The essential oil 620 is contained in the essential oil bottle 220. In this embodiment, a bottle of essential oil can be used for a long time, which is convenient and does not require frequent refilling of essential oil.

[0410] As a specific example, as shown in Figures 45 and 46, Figure 45 is a schematic diagram of an essential oil bottle in a normal state, and Figure 46 is a schematic diagram of an explosion of the essential oil bottle. The essential oil bottle 220 includes a bottle body 221, a bottle cap 222, and a push rod motor 223. The bottle body 221 and the bottle cap 222 are connected to each other, and the push rod motor 223 is connected to the bottle cap 222 to control the opening or closing of the bottle cap 222. In this solution, the bottle cap 222 is controlled by the push rod motor 223, and the essential oil 620 does not evaporate to the outside when not in use, thereby reducing the amount of essential oil 620 used and reducing costs.

[0411] Specifically, the moving assembly 100 is provided with an essential oil 620 bracket 131 that secures the essential oil bottle 220. The push rod motor 223 includes a push rod body 224 and a telescopic rod 225. The push rod body 224 is secured to the essential oil 620 bracket 131. The telescopic rod 225 is connected to the push rod body 224 at one end and secures the bottle cap 222 at the other end. The push rod body 224 has two telescopic control wires, each with a positive and negative connection, electrically connected to a power source. The positive connection pushes the telescopic rod 225 outward, controlling the bottle cap 222 to cover the bottle body 221; the negative connection retracts the telescopic rod 225 into the push rod body 224, controlling the bottle cap 222 to open. Once the telescopic rod 225 is in place, the push rod motor 223 automatically stops. Therefore, only the direction of the power source needs to be controlled, without the need for additional position detection, resulting in a simple control method.

[0412] Furthermore, the opening of the essential oil bottle 220 is lower than the center axis of the curved double-flared flow guide 310. Since the essential oil 620 rises as it evaporates, the opening of the essential oil bottle 220, when placed below the center axis of the curved double-flared flow guide 310, allows the volatile essential oil 620 to fully cover the center area of ​​the curved double-flared flow guide 310, allowing it to fully contact the cold air and enhance the essential oil 620's attraction to the cold air.

[0413] Furthermore, as shown in FIG47 , the essential oil bottle 220 further includes a first diffuser 226. One end of the first diffuser 226 is inserted into the bottle body 221 to contact the essential oil 620, while the other end of the first diffuser 226 extends outside the bottle body 221. In this embodiment, the essential oil 620 in the bottle evaporates naturally, resulting in a small amount of evaporation and a limited diffusion range. The addition of the first diffuser 226 increases the volatility of the essential oil 620 and allows it to evaporate over a wider range, making it easier for cold air to connect with the essential oil 620.

[0414] At this point, the top of the first diffuser 226 is lower than the center axis of the dual-flared flow guide. Since the essential oil 620 evaporates upward from the top of the first diffuser 226, setting the height of the evaporation surface of the essential oil 620 lower than the center axis of the flow guide allows the evaporated essential oil 620 to fully cover the area around the small opening 310b of the corresponding channel in the dual-flared flow guide, enhancing the essential oil 620's attraction to cold air.

[0415] Specifically, the first fragrance diffuser 226 includes a volatilizer stick, which is widely used in the field of aromatherapy, has good volatilization effect, and is relatively low in cost.

[0416] Furthermore, the bottle cap 222 is increased with a ball head 227 having a hollow hole, and the ball head 227 wraps the portion of the volatilizing stick exposed outside the bottle cap 222 to control volatility; in this solution, the volatilizing stick is wrapped with the ball head 227, and the size and number of the diffusion holes on the outer wall of the ball head 227 can be used to control the amount of essential oil 620 diffused into the external environment.

[0417] If the essential oil bottle 220 is directly opened and exposed to the air, dust, microorganisms, etc. in the air can easily enter the essential oil bottle 220, causing the essential oil 620 to deteriorate; therefore, adding a ball head 227 at the bottle mouth can reduce the entry of debris and extend the service life of the essential oil 620.

[0418] Furthermore, while the use of a volatilizing stick can prevent external debris and microorganisms from entering the essential oil bottle 220 while allowing the essential oil 620 to reach the bottle opening for better dissemination, the volatilization speed of the essential oil 620 is very high. Therefore, the ball head 227 is used to wrap the ball head 227. The size and number of the diffusion holes on the outer wall of the ball head 227 can be used to control the amount of essential oil 620 that diffuses into the external environment.

[0419] For fixing the essential oil bottle 220 , the bottle cap 222 and the push rod motor 223 may be integrated together to facilitate assembly and overhaul and maintenance.

[0420] As another embodiment, as shown in Figure 48, the cold-removing air device 10 also includes an oil storage tank 230, a drip nozzle 231 and a second fragrance diffusion component 232. The oil storage tank 230 and the second fragrance diffusion component 232 are respectively connected to the moving component 100. The moving component 100 controls the oil storage tank 230 and the second fragrance diffusion component 232 to move in a direction away from the user to be cold-removed. The oil storage tank 230 is arranged above the second fragrance diffusion component 232, that is, on the side away from the moving component 100; the drip nozzle 231 is arranged between the oil storage tank 230 and the second fragrance diffusion component 232, and is connected to the oil storage tank 230; the oil storage tank 230 stores essential oil 620, and the drip nozzle 231 is connected to the oil storage tank 230 to drip the essential oil 620 in the oil storage tank 230 onto the second fragrance diffusion component 232.

[0421] At this point, the top of the second fragrance diffuser 232 is lower than the central axis of the diversion module 300. Since the essential oil 620 evaporates from the surface of the second fragrance diffuser 232 after landing on it, setting the height of the evaporation surface of the essential oil 620 lower than the central axis of the diversion module 300 allows the evaporated essential oil 620 to fully cover the small opening 310b of the corresponding channel in the diversion module 300, thereby enhancing the essential oil 620's attraction to cold air.

[0422] In this embodiment, the second fragrance diffuser 232 directly exposes the essential oil 620 completely to the air, thereby increasing the volatility of the essential oil 620 and establishing a connection with the cold air more quickly.

[0423] The second diffuser 232 can be made of wood, stone (such as crystal or volcanic rock), or other materials that can aid in the volatilization of the essential oil 620. Of course, a combination of materials can also be used. For example, crystal gravel can be placed in a sandalwood sachet, essential oil 620 can be dripped into the sachet, and then the sachet can be closed. The sachet itself has small holes that allow the essential oil 620 to evaporate. The essential oil 620 mixed with the crystal gravel in the sachet will evaporate more slowly, reducing the amount of essential oil 620 used and saving costs.

[0424] As shown in FIG49 , the cold-dispelling device 10 further includes a sealing cover 700. Taking the diversion module 300 as an example, which uses a double-horn diversion member 315 with a gradual curvature, the essential oil bottle 220 and the double-horn diversion member 315 with a gradual curvature are both placed on the mounting platform 117. The sealing cover 700 covers the essential oil bottle 220 and the diversion module 300, and is also fixed to the mounting platform 117. The sealing cover 700 is provided with a through hole 710 corresponding to the end of the double-horn diversion member 315 with a gradual curvature and the direction of the user. In this solution, if the essential oil bottle 220 is directly opened and exposed to the air, dust, microorganisms, etc. in the air can easily enter the essential oil bottle 220, causing the essential oil 620 to deteriorate. Therefore, a sealing cover 700 is added to the bottle mouth to reduce the entry of debris and extend the service life of the essential oil 620.

[0425] Furthermore, the sealing cover 700 is made of an opaque material, so that the outside world cannot see the inside of the sealing cover 700, thereby improving the aesthetic effect of the cold-removing device 10. Moreover, through holes 710 can be provided on each side of the sealing cover 700 to further improve air circulation.

[0426] As shown in FIG. 50 , an embodiment of the present application further provides a specific guide bracket 500 , which can be used in the mobile assembly 100 or other mobile assemblies 100 in the above-mentioned various embodiments to fix the guide module 300 .

[0427] The flow guide bracket 500 is used to secure a curved dual-flared flow guide 310, a dual-flared flow guide 315 with a gradually varying curvature in a series flow guide assembly 320, or the outermost dual-flared flow guide 315 with a gradually varying curvature in a nested flow guide assembly 330. It will be appreciated that when the flow guide module 300 is a series flow guide assembly 320 or a flow guide 340, there are multiple flow guide brackets 500, each of which secures a nested flow guide assembly 330 or a curved dual-flared flow guide 310.

[0428] Specifically, the deflector bracket 500 includes a support column 540 and a fixing seat 550. The bottom of the support column 540 is fixed to the mobile assembly 100 by screws, clamping, welding, etc. The fixing seat 550 is arranged on the top of the support column 540, and the fixing seat 550 and the support column 540 can be an integrally formed structure. The fixing seat 550 is provided with a notch 510 at one end of the fixing seat 550 away from the support column 540. The inner wall of the notch 510 is aligned with the outer wall of the deflector module 300. The notch 510 passes through the fixing seat 550 along the central axis of the dual-speaker deflector, and the intersection of the notch 510 and the fixing seat 550 on both sides forms a chamfered surface. The small end 310b area of ​​the corresponding channel in the deflector module 300 is fixed in the notch 510.

[0429] Taking a curvature gradient double-horn body flow guide 315 as an example, since the channel inside the curvature gradient double-horn body flow guide 315 is a double-horn symmetrical structure, the outer wall of the curvature gradient double-horn body flow guide 315 is also a curved surface, and the small mouth end 310b area corresponding to the channel in the curvature gradient double-horn body flow guide 315 is fixed at the slot 510 of the flow guide bracket 500, and the edges on both sides of the slot 510 are chamfered inclined surfaces, which fit the outer wall of the curvature gradient double-horn body flow guide 315. Under the guidance of the four outward-inclined chamfered inclined surfaces on both sides of the slot 510, even if the curvature gradient double-horn body flow guide 315 is deformed, it can be ensured that there are four contact points between the curvature gradient double-horn body flow guide 315 and the slot 510, so that the curvature gradient double-horn body flow guide 315 can be stably stuck on the slot 510.

[0430] Furthermore, the end of the slot 510 toward the curvature gradient double-horn flow guide 315 is made into an outwardly inclined slope to cater to the shape of the outer wall of the curvature gradient double-horn flow guide 315, which can increase the contact area between the slot 510 and the curvature gradient double-horn flow guide 315 and improve the fixing strength.

[0431] Furthermore, as shown in Figure 51, the deflector bracket 500 also includes a fixing cover 520, which is arranged on the above-mentioned slot 510, and the inner wall of the fixing cover 520 is fitted with the outer wall of the curvature gradient double-horn deflector 315, and the two ends of the fixing cover 520 are fixed to the two sides of the fixing seat 550 by screws, and the lower half of the small mouth end 310b area corresponding to the channel in the curvature gradient double-horn deflector 315 is stuck to the slot 510 for positioning; the upper half of the small mouth end 310b area corresponding to the channel in the curvature gradient double-horn deflector 315 is buckled and locked by the fixing cover 520.

[0432] Furthermore, as shown in Figure 52, a cover 530 is added to cover the gradually changing curvature dual-flared flow guide 315. Specifically, the cover 530 is a sealed rectangular frame formed from an aluminum alloy sheet. The bottom of the flow guide bracket 500 is fixed to the center of the cover 530. The front and rear ends of the cover 530 each have multiple air holes 531. The area of ​​the air holes 531 is consistent with the size of the large opening 310a of the gradually changing curvature dual-flared flow guide 315. The top of the cover 530 serves as a lid. After the gradually changing curvature dual-flared flow guide 315 is installed inside the cover 530, the lid is closed and secured with rivets. Adding the cover 530 can improve dust prevention and reduce dust adhesion to the flow guide, which could affect the efficacy.

[0433] The air holes 531 are arranged in multiple concentric circles, their shape matching the wide-mouth end 310a of the gradually curving dual-flared air guide 315. This provides more uniform airflow than a rectangular arrangement. Too large air holes 531 can easily let in dust, while too small can compromise ventilation. A 1.5-2mm diameter was chosen, ultimately resulting in a 1.8mm diameter.

[0434] Furthermore, after adding the cover 530, the two large openings 310a of the gradually curved dual-flared flow guide 315 should be as close as possible to the front and rear ends of the cover 530 to improve air intake. Considering the large tolerances in sheet metal processing, this spacing can be set at 5mm. The front end of the cover 530 faces the human body, while the rear end faces the burning surface of the moxa stick 610. The distance between the rear end and the burning surface of the moxa stick 610 can be set at 12cm.

[0435] Finally, regarding the control module 400, the control module 400 includes:

[0436] A starting module is used to start the power supply of the cold-removing device 10 and put it into a standby state;

[0437] The first stop module, after receiving the start instruction from the operator or remote to start the cold-removing device 10 to perform the physiotherapy action, stays for 10-60 seconds and issues a move instruction;

[0438] The moving module is used to control the moving component 100 to move 50cm-200cm at a constant speed of 2-5mm / s after receiving the moving instruction; and send a stop instruction after reaching the predetermined position;

[0439] The second stop module is used to delay 10-60s after receiving the stop command and issue a reset command;

[0440] The reset module is used to control the moving component 100 to return to the initial position after receiving the reset instruction.

[0441] It has been verified that after receiving the start command, pausing for 10-60 seconds allows the energy source 600 and the cold air to establish a relatively stable connection, while the cold air is still in the state of being drawn out. At this time, the energy source 600 and the diversion module 300 are controlled to move, moving along the trend of the cold air being drawn out, and the connection is not easily interrupted, which can enhance the trend of drawing out the cold air. It has been verified that within the range of controlling the moving component 100 to move at a constant speed of 2-5mm / s, the connection between the cold air and the energy source 600 is not easily interrupted during the movement, and the cold air can be continuously drawn out. It has been verified that at a constant speed of 2-5mm / s, the moving component 100 moves 50cm-200cm, and the cold air can be continuously drawn out during the movement; and after the energy source 600 finishes moving, the drawing out trend can still be maintained. It has been verified that within the range of 10-60 seconds after the second stop module controls the moving component 100 to move, the connection between the cold air and the energy source 600 tends to be stable, and the cold air and the energy source 600 can establish a natural and stable connection. After adding the reset module, there is no need to adjust the cold-removing device 10, and the next round of use can be started directly, which is more efficient.

[0442] When the energy source 600 uses moxa products, the embodiment of the present application can better stimulate the moxa products' attraction to cold air, increase the utilization rate of moxa products, and improve the use effect of the cold-dispelling device 10 by adaptively adjusting the size of the diversion module 300 and the setting parameters of the control module 400; at this time, the first preset time is 10-30 seconds, the first preset distance is 70cm-120cm, and the second preset time is 10-20 seconds. Similarly, when the energy source 600 uses essential oil 620, the embodiment of the present application can better stimulate the essential oil 620's attraction to cold air, increase the utilization rate of the essential oil 620, and improve the use effect of the cold-dispelling device 10 by adaptively adjusting the size of the diversion module 300 and the setting parameters of the control module 400; at this time, the first preset time is 15-30 seconds, the first preset distance is 60cm-100cm, the moving speed is 2-5mm / s, and the second preset time is 10-20 seconds.

[0443] Optionally, the control module 400 further includes a voice function module for issuing a voice reminder after receiving a reset instruction to remind the user to end the physical therapy.

[0444] When the moxa products and guide pieces reach the end position, users and operators may not be able to see it in time. By adding a voice function module, timely reminders can be provided to help users and operators know the specific stages of the treatment.

[0445] Optionally, the cold-dispelling device 10 is provided with a button (not shown in the figure), which is connected to the starting module and is used to issue a start treatment, and one-button control the mobile component 100 to start, run, reset and end. One-button start, convenient operation.

[0446] Correspondingly, as shown in FIG53 , the present application also provides a method for using a device for removing cold air, which is used for the above-mentioned device for removing cold air, and the method for using the device comprises the following steps:

[0447] S1: Align one end of the diversion module with the user to be de-chilled, and align the other end with the energy source on the energy source fixing device, so that the distance between the diversion module and the user to be de-chilled is a first alignment distance, and the distance between the diversion module and the energy source is a second alignment distance;

[0448] S2: After waiting for a first preset time, the control module drives the moving component to drive the energy source and the diversion module to move a first preset distance away from the user to be cleared of cold air.

[0449] In step S1, the two ends of the channel in the diversion module are respectively aligned with the user to be cleared of cold and the energy source; the first alignment distance is between 5-30cm, and the second alignment distance is between 5-30cm; of course, it can be adjusted accordingly according to actual conditions.

[0450] In step S2, the first preset time is 10-300 seconds (to avoid excessive waiting, it can be further limited to 10-60 seconds), and the first preset distance is 50-200 cm. Moreover, during the process of the moving component driving the energy source and the diversion module to move the first preset distance away from the user to be dispelled cold, the movement speed of the energy source and the diversion module is consistent and uniform, and the movement speed is between 2 mm / s and 5 mm / s.

[0451] After step S2, the energy source and the flow guiding module stay for a second preset time (eg, 10-300 s, which can be further limited to 10-60 s to avoid waiting too long).

[0452] It has been verified that within the second preset time interval, the connection between the cold air and the energy source tends to be stable, and the cold air and the energy source can establish a natural and stable connection. At this time, there is no need to use the diversion module, and the cold air and the energy source can be directly connected. The connection between the cold air and the energy source will not be interrupted, and the cold air can still be drawn out of the body. Therefore, the energy source can be removed, and the user can move to another place to continue physical therapy, leaving the cold air removal equipment free for other users to use, thereby improving the utilization efficiency of the equipment. Of course, it is also feasible to keep the energy source still and remove the diversion module. At this time, the connection between the cold air and the energy source will not be interrupted.

[0453] When the energy source is an wormwood product, as shown in FIG54 , the method for using the cold-dispelling device includes the following steps:

[0454] SA1: The distance between the moxa product of the cold-removing device and the user to be cold-removed is set to a first preset alignment distance;

[0455] SA2: Control the mobile component to wait for a first preset time;

[0456] SA3: controlling the moving assembly to drive the moxa product and the diversion module to move simultaneously a first preset distance in a direction away from the user to be de-cold-expelled;

[0457] SA4: controlling the moving assembly to cause the energy source and the flow guiding module to stay for a second preset time;

[0458] SA5: Remove the moxa product from the moving component.

[0459] Among them, in step SA2, the first preset time is 10-30s; in step SA3, the first preset distance is 70cm-120cm; in step SA4, the second preset time is 10-20s. It has been verified that within the interval of the second preset time, the connection between the cold air and the moxa product tends to be stable, and the cold air and the moxa product can establish a natural and stable connection. At this time, there is no need to use a guide component, and the cold air and the moxa product can be directly connected. The connection between the cold air and the moxa product will not be interrupted, and the cold air can still be drawn out of the body. Therefore, the moxa product can be removed, and the user can move to another place to continue physical therapy, and the cold-removing equipment can be emptied for other users to use, thereby improving the utilization efficiency of the equipment. Of course, it is also feasible to keep the moxa product still and remove the guide component. At this time, the connection between the cold air and the moxa product will not be interrupted.

[0460] It should be noted that when the device is started, the moxa product remains in a ignited state, that is, before step SA1, the moxa product is ignited, and in step SA5, the ignited moxa product is removed. After step SA5, the user to dispel the cold has direct contact with the burning moxa product; when the moxa product is extinguished or burned out, the entire therapy process ends.
