Description

Diversion component, cold-dispelling device and use method thereof Technical Field

[0001] The present application relates to the field of health care equipment, and in particular to a diversion component, a cold-removing device, and a method of using the same. Background Art

[0002] The applicant’s previous case PCT / CN2023 / 121357, Series Guide Components, Cold-Removing Equipment, and Method of Use thereof, states that by connecting multiple series-connected double-horn guides with a gradient curvature, the impact of the external environment can be reduced, making the process of drawing out the cold air more stable. However, further experiments by the inventors revealed that the cold air drawn out by the multiple series-connected double-horn guides with a gradient curvature was not sufficiently concentrated, and when the moving distance increased or the moving speed was faster, the process of drawing out the cold air still had a relatively obvious attenuation.

[0003] The purpose of this application is to provide a diversion component, a cold air removal device and a method of use thereof, which can further improve the concentration of the cold air drawn out and make the process of drawing out the cold air more stable.

[0004] The present application discloses a flow guide component, which includes at least one step-by-step decreasing flow guide unit, and the step-by-step decreasing flow guide unit includes at least three double-horn flow guide pieces with gradually changing curvatures. The double-horn flow guide piece with gradually changing curvatures is an axially symmetrical structure, including a first horn and a second horn symmetrically arranged, the first horn and the second horn both having a large mouth end and a small mouth end, the diameter of the large mouth end being larger than the diameter of the small mouth end, the small mouth end of the first horn and the small mouth end of the second horn being connected to form a central through hole; the inner wall of the first horn has an arc line along the central axis of the double-horn flow guide piece with gradually changing curvature, and the arc line is concave toward the central axis; in the step-by-step decreasing flow guide unit, the central axes of all the double-horn flow guide pieces with gradually changing curvatures are on the same straight line, and the diameters of the central through holes of the double-horn flow guide pieces with gradually changing curvatures decrease one by one along the central axis of the step-by-step decreasing flow guide unit.

[0005] In this solution, multiple dual-flare flow guides with gradually decreasing diameters are connected in series, guiding the cold air toward a more concentrated state. This reduces interruptions and ensures a more stable cold air extraction process. In actual use, the inventors found that when three or more dual-flare flow guides with gradually decreasing diameters are connected in series, the flow guide assembly can stably extract cold air from the human body without even moving it.

[0006] Optionally, in the step-by-step decreasing guide unit, the size of the double-horn guide member with gradually changing curvature is proportionally reduced along the central axis of the step-by-step decreasing guide unit.

[0007] In this solution, the curvature-gradient double-horn body guide parts have the same shape and are proportionally reduced in size, which has better consistency. The process of drawing out the cold air will not produce obvious mutations, and the drawing-out process is more stable.

[0008] Optionally, in the step-by-step decreasing guide unit, the size of the double-horn guide member with gradually changing curvature is proportionally reduced by 60%-90% along the central axis of the step-by-step decreasing guide unit.

[0009] Optionally, in the two adjacent double-flare flow guide members with gradually changing curvatures of the step-by-step decreasing flow guide unit, the spacing between the large-mouth ends of the two adjacent double-flare flow guide members with gradually changing curvatures is equal to 0.8-1.2 times the diameter of the large-mouth end of the smaller-sized double-flare flow guide member with gradually changing curvatures.

[0010] In this solution, it has been verified that the distance between the double-horn-shaped flow guide pieces with gradual curvature is set according to the above-mentioned distance, the cold air flows more smoothly in the double-horn-shaped flow guide pieces with gradual curvature, without obvious blockage or interruption, and the process of leading out the cold air is more stable.

[0011] Optionally, the guide assembly is a serial decreasing guide assembly, and the serial decreasing guide assembly includes at least two step-by-step decreasing guide units, and the central axes of at least two of the step-by-step decreasing guide units are on the same straight line; the curvature gradient double-horn guide member with the largest central through hole diameter of the latter step-by-step decreasing guide unit faces the curvature gradient double-horn guide member with the smallest central through hole diameter of the former step-by-step decreasing guide unit; wherein, the number of the curvature gradient double-horn guide members in the former step-by-step decreasing guide unit is greater than the number of the curvature gradient double-horn guide members in the latter step-by-step decreasing guide unit; the diameter of the largest central through hole in the former step-by-step decreasing guide unit is greater than the diameter of the largest central through hole in the latter step-by-step decreasing guide unit.

[0012] In this solution, the more curvature gradient double-horn body guide pieces that are connected in series with the step-by-step decreasing guide units, the higher the concentration of the cold air drawn out, and the more stable the drawing-out process. However, when the smallest curvature gradient double-horn body guide piece remains unchanged and the ratio of size enlargement remains unchanged, the length of the step-by-step decreasing guide unit will increase, and the width and height will also increase. In order to reduce the volume, multiple step-by-step decreasing guide units are used, and the number and size of the curvature gradient double-horn body guide pieces of the latter stage do not exceed that of the previous stage. In this way, when the total number of curvature gradient double-horn body guide pieces remains unchanged, the width and length of the product can be effectively controlled (that is, the diameter of the largest curvature gradient double-horn body guide piece will not be too large), which is beneficial to reducing the volume of the product.

[0013] Optionally, the diameter of the smallest central through hole in the step-by-step decreasing guide unit of the latter stage is smaller than or equal to the diameter of the smallest central through hole in the step-by-step decreasing guide unit of the previous stage.

[0014] In this solution, the minimum central through hole determines the concentration of cold air. The minimum central through hole of the step-by-step guide unit in the latter stage cannot exceed that of the previous stage, ensuring that the concentration of cold air will not decrease after multiple stages are connected in series.

[0015] Optionally, the guide assembly is a gate-shaped guide assembly, which includes an input arm, a connecting arm and an output arm, the input arm, the connecting arm and the output arm are connected end to end in sequence, the input arm and the output arm are arranged in parallel, the connecting arm is located between the input arm and the output arm, and is arranged perpendicular to the input arm and the output arm; the input arm, the connecting arm and the output arm respectively include at least one of the step-by-step decreasing guide units; and, the double-flare guide piece with a gradient curvature having the largest central through hole in the connecting arm is close to the double-flare guide piece with a gradient curvature having the smallest central through hole in the input arm; the double-flare guide piece with a gradient curvature having the smallest central through hole in the connecting arm is close to the double-flare guide piece with a gradient curvature having the largest central through hole in the output arm.

[0016] In this solution, after the cold air is drawn out, a void will appear in the body. It takes a long time for the body to generate positive energy to fill the void, resulting in low efficiency. In this solution, multiple step-by-step descending flow guide units are arranged in a "gate" shape. The tail of the step-by-step descending flow guide unit of the input arm (the section of the double-flared flow guide with the smallest central through hole and gradually changing curvature) is adjacent to the head of the step-by-step descending flow guide unit of the connecting arm (the section of the double-flared flow guide with the smallest central through hole and gradually changing curvature), and the two are arranged perpendicularly. The cold air coming out of the input arm diffuses into the external space; since the cold air is relatively turbid and stagnant, most of the cold air will not directly enter the connecting arm, while the outside world itself has positive energy, which is relatively clear and smooth. A small part of the cold air and the positive energy enter the connecting arm, forming a first-level filtration; similarly, only a small part of the cold air coming out of the connecting arm enters the input arm, forming a second-level filtration. The filtered air is mainly positive energy, which is reintroduced into the human body through the output arm, thus realizing the exchange of cold air in the human body and positive energy from the outside world. While the cold air in the human body is reduced, the positive energy can be replenished in time, which greatly improves the efficiency of replenishing the positive energy.

[0017] Optionally, the number of double-flared flow guide members with a gradual curvature in the connecting arm is greater than the number of double-flared flow guide members with a gradual curvature in the input arm; and the number of double-flared flow guide members with a gradual curvature in the input arm is equal to the number of double-flared flow guide members with a gradual curvature in the output arm.

[0018] In this solution, the number of double-horn-shaped flow guides with a gradual curvature of the connecting arm exceeds that of the input arm, which increases the attraction to the input arm and can further stabilize the process of drawing out the cold air; the number of double-horn-shaped flow guides with a gradual curvature of the input arm and the output arm is the same, which can maintain a balance between the drawn-out cold air and the supplemented positive energy.

[0019] Optionally, the input arm and the output arm each have only one step-by-step decreasing guide unit, and the step-by-step decreasing guide unit includes five double-horn guide members with gradually varying curvatures; the connecting arm has two step-by-step decreasing guide units, namely a first step-by-step decreasing guide unit and a second step-by-step decreasing guide unit, the central axes of the first step-by-step decreasing guide unit and the second step-by-step decreasing guide unit are located in the same straight line, the first step-by-step decreasing guide unit includes five double-horn guide members with gradually varying curvatures, and the second step-by-step decreasing guide unit includes three double-horn guide members with gradually varying curvatures. Guide piece; the double-flare guide piece with a gradually changing curvature and the largest central through hole in the first step-by-step decreasing guide unit is close to the double-flare guide piece with a gradually changing curvature and the smallest central through hole in the input arm; the double-flare guide piece with a gradually changing curvature and the smallest central through hole in the first step-by-step decreasing guide unit is facing the double-flare guide piece with a gradually changing curvature and the largest central through hole in the second step-by-step decreasing guide unit; the double-flare guide piece with a gradually changing curvature and the smallest central through hole in the second step-by-step decreasing guide unit is close to the double-flare guide piece with a gradually changing curvature and the largest central through hole in the output arm.

[0020] In this solution, the connecting arm is formed by two step-by-step decreasing guide units connected in series, and the step-by-step decreasing guide unit of the latter stage adopts three double-horn guide parts with gradually varying curvatures, which meets the requirement of guiding cold air without moving. Using fewer double-horn guide parts with gradually varying curvatures enhances the cold air guiding effect, which is conducive to reducing costs and reducing product volume.

[0021] Optionally, the diversion component is a three-dimensional diversion component, the three-dimensional diversion component includes at least one three-dimensional step-by-step decreasing diversion module, the three-dimensional step-by-step decreasing diversion module includes four step-by-step decreasing diversion units, namely the third step-by-step decreasing diversion unit, the fourth step-by-step decreasing diversion unit, the fifth step-by-step decreasing diversion unit and the sixth step-by-step decreasing diversion unit; the sixth step-by-step decreasing diversion unit is located in the area surrounded by the third step-by-step decreasing diversion unit, the fourth step-by-step decreasing diversion unit and the fifth step-by-step decreasing diversion unit; the large mouth ends of the double-horn body diversion pieces with the largest curvature gradient and the largest central through hole in the third step-by-step decreasing diversion unit, the fourth step-by-step decreasing diversion unit and the fifth step-by-step decreasing diversion unit are located in the same plane, the sixth step-by-step decreasing diversion unit is retracted from the plane, and the large mouth end of the double-horn body diversion piece with the largest curvature gradient and the largest central through hole in the sixth step-by-step decreasing diversion unit is outside the plane.

[0022] In this solution, the large mouth end of the double-horn-body guide member with a gradual curvature and the largest central through hole in the sixth step-by-step decreasing guide unit is outside the plane and is indented toward the double-horn-body guide member with a gradual curvature and the smallest central through hole. In this way, the input ends of the four step-by-step decreasing guide units form a three-dimensional cold air convergence surface, which is similar to the smoke inlet of a chimney, and can significantly enhance the cold air convergence ability and improve the cold air extraction efficiency.

[0023] Optionally, the number of the double-horn body guide members with gradually varying curvatures in the third step-by-step decreasing guide unit, the fourth step-by-step decreasing guide unit, the fifth step-by-step decreasing guide unit and the sixth step-by-step decreasing guide unit are the same, and the sizes of the corresponding double-horn body guide members with gradually varying curvatures are equal; the central axes of the third step-by-step decreasing guide unit, the fourth step-by-step decreasing guide unit, the fifth step-by-step decreasing guide unit and the sixth step-by-step decreasing guide unit are parallel; the double-horn body guide member with gradually varying curvatures having the largest central through hole in the third step-by-step decreasing guide unit, the fourth step-by-step decreasing guide unit, the fifth step-by-step decreasing guide unit and the sixth step-by-step decreasing guide unit are respectively located at the four end points of a regular triangular pyramid.

[0024] Furthermore, the four step-by-step decreasing diversion units have the same size and number, which can guide the cold air evenly and improve the stability of the cold air diversion process.

[0025] Optionally, the three-dimensional air guide component includes two three-dimensional step-by-step decreasing air guide modules, namely a first three-dimensional step-by-step decreasing air guide module and a second three-dimensional step-by-step decreasing air guide module, whose central axes are located in the same straight line. The number of double-horn air guide parts with gradually changing curvature of the step-by-step decreasing air guide unit in the first three-dimensional step-by-step decreasing air guide module is greater than the number of double-horn air guide parts with gradually changing curvature of the step-by-step decreasing air guide unit in the second three-dimensional step-by-step decreasing air guide module; and the central axes of the corresponding step-by-step decreasing air guide units in the first three-dimensional step-by-step decreasing air guide module and the second three-dimensional step-by-step decreasing air guide module are on the same straight line.

[0026] In this solution, two three-dimensional step-by-step decreasing guide modules are connected in series. Compared with a single three-dimensional step-by-step decreasing guide module with the same number of double-horn guide parts with gradually changing curvature, the volume of the product can be reduced while the cold air guiding effect is basically the same. Optionally, the three-dimensional air guide component is a gate-shaped three-dimensional air guide component, which includes a three-dimensional input arm, a three-dimensional connecting arm and a three-dimensional output arm. The three-dimensional input arm, the three-dimensional connecting arm and the three-dimensional output arm are connected end to end in sequence, the three-dimensional input arm and the three-dimensional output arm are arranged in parallel, the three-dimensional connecting arm is located between the three-dimensional input arm and the three-dimensional output arm, and is arranged vertically with the three-dimensional input arm and the three-dimensional output arm; the three-dimensional input arm, the three-dimensional connecting arm and the three-dimensional output arm respectively include at least one three-dimensional step-by-step decreasing air guide module; and, the curvature gradient double-horn body air guide piece with the largest central through hole in the three-dimensional connecting arm is close to the curvature gradient double-horn body air guide piece with the smallest central through hole in the three-dimensional input arm; the curvature gradient double-horn body air guide piece with the smallest central through hole in the three-dimensional connecting arm is close to the curvature gradient double-horn body air guide piece with the largest central through hole in the three-dimensional output arm.

[0027] In this solution, a three-dimensional step-by-step decreasing diversion module is used to form a diversion component similar to the shape of a "door", which can improve the efficiency of drawing out cold air and replenishing positive energy.

[0028] Optionally, the present application also discloses a device for dispelling cold air, which includes an energy source and the guide assembly as described above, with the curvature gradient double-horn guide pieces at both ends of the step-by-step decreasing guide unit in the guide assembly being respectively the input end curvature gradient double-horn guide piece and the output end curvature gradient double-horn guide piece, and the size of the input end curvature gradient double-horn guide piece is larger than the size of the output end curvature gradient double-horn guide piece; the energy source is located on the side of the output end curvature gradient double-horn guide piece away from the input end curvature gradient double-horn guide piece; or, the energy source is located between adjacent curvature gradient double-horn guide pieces in the step-by-step decreasing guide unit.

[0029] In this solution, the attraction of the energy source can improve the efficiency of the guide component and the stability of the cold air extraction process.

[0030] Optionally, the energy source is a light source.

[0031] In this solution, the light source is controllable and stable, and does not require replacement or replenishment of consumables, making it an ideal energy source.

[0032] Optionally, the light source includes a light-emitting portion and an optical fiber, the light-incident surface of the optical fiber is arranged opposite to the light-emitting portion, and the light-emitting surface of the optical fiber is arranged opposite to the central through hole of the corresponding rate-gradient double-horn body guide member.

[0033] In this solution, the optical fiber has good guidance properties and can guide the optical fiber to move in a specific direction, which helps to improve the guidance properties of the cold air extraction process and make the cold air extraction process more stable.

[0034] Optionally, the optical fiber is located on a side of the output-end gradient curvature dual-flared flow guide away from the input-end gradient curvature dual-flared flow guide, with the optical fiber's light-emitting surface facing the central through-hole of the output-end gradient curvature dual-flared flow guide. In this solution, light is directed toward the output-end gradient curvature dual-flared flow guide and then toward the input-end gradient curvature dual-flared flow guide (i.e., toward the human body), allowing for faster connection with the cold energy in the human body.

[0035] Optionally, the optical fiber is located between the output-end double-horn flow guide with gradual curvature and an adjacent double-horn flow guide with gradual curvature; the light-emitting surface of the optical fiber faces the central through hole of the output-end double-horn flow guide with gradual curvature.

[0036] In this solution, light is directed toward the double-horn body guide member with a gradual curvature change at the output end and away from the double-horn body guide member with a gradual curvature change at the input end (i.e., the direction of the human body), which can guide the direction of the cold air discharge, allowing the cold air to be discharged along the direction of the light, thereby improving the guidance of the cold air discharge process and making the cold air discharge process more stable.

[0037] Optionally, the flow guide assembly is a serial decreasing flow guide assembly, and the serial decreasing flow guide assembly includes at least two step-by-step decreasing flow guide units, and the central axes of at least two step-by-step decreasing flow guide units are on the same straight line; the curvature gradient double horn flow guide piece with the largest central through hole diameter of the step-by-step decreasing flow guide unit of the next stage faces the curvature gradient double horn flow guide piece with the smallest central through hole diameter of the step-by-step decreasing flow guide unit of the previous stage; the number of the curvature gradient double horn flow guide pieces in the step-by-step decreasing flow guide unit of the previous stage is greater than that of the step-by-step decreasing flow guide unit of the next stage. The number of the double-horn body guide parts with gradually changing curvature in the step-by-step decreasing guide unit; the diameter of the largest central through hole in the step-by-step decreasing guide unit of the previous level is larger than the diameter of the largest central through hole in the step-by-step decreasing guide unit of the next level; the optical fiber is arranged between the double-horn body guide part with gradually changing curvature at the output end and the adjacent double-horn body guide part with gradually changing curvature in the step-by-step decreasing guide unit of the previous level, and the light-emitting surface of the optical fiber faces the central through hole of the double-horn body guide part with gradually changing curvature at the output end in the step-by-step decreasing guide unit of the previous level.

[0038] In this solution, multiple step-by-step decreasing guide units are connected in series, and the optical fiber is set on the first step-by-step decreasing guide unit, close to the human body, which can better establish a connection with the human body's cold air and stabilize the cold air extraction process.

[0041] In this solution, the large opening of the sixth progressively decreasing diversion unit's dual-flared diversion element, with the largest central opening, is positioned outside the plane; it is indented toward the dual-flared diversion element with the smallest central opening. This creates a three-dimensional cold air convergence surface, similar to the smoke inlet of a chimney, significantly enhancing the convergence of cold air and improving its extraction efficiency. The optical fiber is placed on the first three-dimensional progressively decreasing diversion module, close to the human body, enabling a better connection with the body's cold air and stabilizing the extraction process.

[0042] Optionally, there is only one three-dimensional step-by-step decreasing guide module in the three-dimensional guide assembly, and the four optical fibers are respectively located on the side of the output end curvature gradient double horn body guide member in the third step-by-step decreasing guide unit, the fourth step-by-step decreasing guide unit, the fifth step-by-step decreasing guide unit and the sixth step-by-step decreasing guide unit away from the input end curvature gradient double horn body guide member, and the light-emitting surfaces of the four optical fibers are respectively facing the central through holes of the output end curvature gradient double horn body guide member in the four step-by-step decreasing guide units.

[0045] Optionally, the three-dimensional flow guide component includes two three-dimensional step-by-step decreasing flow guide modules, namely a first three-dimensional step-by-step decreasing flow guide module and a second three-dimensional step-by-step decreasing flow guide module.

[0050] In this solution, the diversion component does not move, and no additional moving components are required, which results in a smaller size and lower cost.

[0077] It should be understood that the terms used herein, the specific structures and functional details disclosed are only for describing specific embodiments and are representative. However, the present application can be implemented in many alternative forms and should not be construed as being limited to the embodiments described herein.

[0078] The present application is described in detail below with reference to the accompanying drawings and optional embodiments.

[0079] Example 1:

[0080] Figure 1 is a schematic diagram of a cold-dispelling air device provided in the first embodiment of the present application. As shown in Figure 1, as the cold-dispelling air device provided in the first embodiment of the present application, the cold-dispelling air device 10 includes a guide component 100 and an energy source 700.

[0081] FIG2 is a schematic diagram of a flow guide assembly provided in an embodiment of the present application. As shown in FIG2 , the flow guide assembly 100 includes only one step-by-step decreasing flow guide unit 110 , and the step-by-step decreasing flow guide unit 110 is composed of five double-horn flow guide members 111 with gradually varying curvatures.

[0082] The embodiment of the present application can improve the extraction efficiency of the guide component 100 and improve the stability of the cold air extraction process through the suction effect of the energy source 700.

[0083] Figure 3 is a three-dimensional schematic diagram of a double-horn body flow guide with a gradual curvature. As shown in Figure 3, the two ends of the double-horn body flow guide 111 with a gradual curvature are open and the interior is hollow to form a channel, and the shape of the channel is a double-horn shape; the double-horn body flow guide 111 with a gradual curvature includes a first horn 111a and a second horn 111b, and the first horn 111a and the second horn 111b are the same in size and shape, and the first horn 111a and the second horn 111b are symmetrically arranged.

[0084] Both first horn 111a and second horn 111b have a large opening and a small opening. The large opening is larger in diameter than the small opening. The small openings of first horn 111a and second horn 111b are connected, forming a double-horn-shaped passageway within first horn 111a and second horn 111b. Furthermore, the small openings of first horn 111a and second horn 111b are directly connected, forming a central through hole. The connection is smooth, without abrupt changes or sharp corners.

[0085] Figure 4 is a schematic diagram of the surface change law of the inner wall of the double-horn body flow guide with gradual curvature. As shown in Figure 4, the cross-sectional line of the inner wall of the first horn 111a and the second horn 111b along the central axis of the double-horn body flow guide with gradual curvature 111 is taken as arc s, and the arc s is concave toward the central axis, and the curvature of the arc increases from the large-mouth end of the first horn 111a and the second horn 111b toward the corresponding small-mouth end; the curvature tends to zero as the arc extends toward the large-mouth end; the tangent of the arc corresponding to the endpoint of the large-mouth end of the first horn 111a tends to be perpendicular to the central axis; the arc approaches the central axis toward the small-mouth end of the first horn 111a, but does not intersect.

[0086] FIG5 is a schematic diagram of the outline of another dual-flare flow guide with a gradually varying curvature. As shown in FIG5 , the dual-flare flow guide 111 with a gradually varying curvature includes, in addition to an axisymmetrically arranged first flare 111a and second flare 111b, a throat 111c. The small ends of the first and second flares 111a and 111b are connected by the throat 111c, with a smooth transition between the small ends of the first and second flares 111a and 111b and the throat 111c. The throat 111c is hollow and cylindrical, open at both ends.

[0087] Among them, the throat 111c can be a cylindrical shape with uniform cross-sectional dimensions at all locations, and its cross section is a straight line parallel to the central axis, allowing the cold air to transition from the first speaker 111a to the second speaker 111b along the direction parallel to the central axis, thereby achieving a better cold air guidance effect. Since the interiors of the first speaker 111a and the second speaker 111b are concave arc surfaces, the length of the throat 111c is shortened as much as possible. This allows the cold air to be guided from the first speaker 111a, the throat 111c, to the second speaker 111b more smoothly, which is conducive to improving the guidance effect of evil spirits. At this time, the through-hole position at the narrowest point of the channel of the curvature gradient dual-speaker body guide 111, that is, the central through-hole position of the curvature gradient dual-speaker body guide 111, is the cross-section of any point of the throat 111c.

[0088] Of course, the throat 111c can also adopt an inward-concave arc surface, and the curvature change rule of this arc surface is different from that of the first speaker 111a and the second speaker 111b. The curvature of the arc surface of the throat 111c is smaller than the curvature of the arc surface of the first speaker 111a and the second speaker 111b, and the closer to the center of the throat 111c, the flatter the surface of the throat 111c is. In this way, the guiding process of the cold air in the curvature gradient double-horn body guide 111 will be smoother, further improving the guiding effect of the cold air. Among them, the length of the throat 111c can be one tenth to one third of the total length of the curvature gradient double-horn body guide 111. At this time, the position of the through hole at the narrowest point of the channel of the curvature gradient double-horn body guide 111, that is, the central through hole position of the curvature gradient double-horn body guide 111, is the cross-section of the center position of the throat 111c.

[0089] Moreover, the interior of the double-horn flow guide member 111 with gradually varying curvature may be provided with transverse and longitudinal guide grooves, and the guide grooves are grooves, so as to further enhance the guiding effect on the evil spirits.

[0090] As shown in FIG2 , in the embodiment of the present application, five serially arranged double-flared flow guides 111 with gradually varying curvatures are numbered a, b, c, d, and e. The five double-flared flow guides 111 with gradually varying curvatures are fixed to a base and arranged sequentially in the order of their numbers. Furthermore, the large end of a is positioned opposite the large end of b, the large end of b is positioned opposite the large end of c, the large end of c is positioned opposite the large end of d, and the large end of d is positioned opposite the large end of e.

[0091] Furthermore, the central axes of the five double-horn flow guide members 111 with gradually varying curvatures, a, b, c, d, and e, are on the same straight line, and along the central axis direction of the step-by-step decreasing flow guide unit 110, the diameters of the central through holes of the double-horn flow guide members 111 with gradually varying curvatures decrease one by one, that is, the central through hole diameter of a is greater than the central through hole diameter of b, the central through hole diameter of b is greater than the central through hole diameter of c, the central through hole diameter of c is greater than the central through hole diameter of d, and the central through hole diameter of d is greater than the central through hole diameter of d.

[0092] The embodiment of the present application utilizes five central through-holes of dual-flared bodies with gradually decreasing curvature connected in series, with the diameters of these central through-holes gradually decreasing. This can guide the cold air toward a gradually concentrated state, making the cold air extraction process less likely to be interrupted and more stable. In actual use, the inventors have found that as long as three or more dual-flared bodies with gradually decreasing curvature through-hole diameters are connected in series, the guide assembly 100 can stably extract the cold air from the human body without even moving it.

[0093] As shown in Figure 2, as one embodiment of the present application, in a step-by-step decreasing flow guide unit 110, the five dual-flared flow guide members 111 with gradually varying curvature have different outline dimensions, with b, c, d, and e all being proportionally scaled versions of a. It will be understood that the outline dimensions referred to here include the length, width, large end diameter, small end diameter, and center hole diameter of the dual-flared flow guide member 111 with gradually varying curvature.

[0094] Furthermore, along the central axis of the step-by-step deflector unit 110, i.e., from direction a to e, the size of the gradually-decreasing dual-flared deflector 111 decreases proportionally. Because the gradually-decreasing dual-flared deflectors 111 have the same shape and proportionally reduced size, they provide greater consistency, preventing noticeable abrupt changes in the cold air extraction process and ensuring a more stable extraction process.

[0095] Specifically, the reduction ratio is 80%. That is, of two adjacent dual-flared-curvature flow guides 111, the smaller dual-flared-curvature flow guide 111 has an outline dimension that is equal to the larger dual-flared-curvature flow guide 111, and the outline dimensions are reduced by 80%. For example, for dual-flared-curvature flow guides 111 numbered a and b, the outline dimensions of a are 80% of the outline dimensions of b. In practical applications, a reduction ratio of 60% to 90% is sufficient.

[0096] Moreover, in this embodiment, in two adjacent double-flared-curvature flow guides 111, the spacing between the large-mouth ends of the two adjacent double-flared-curvature flow guides 111 is equal to 0.8-1.2 times the diameter of the large-mouth end of the smaller double-flared-curvature flow guide 111. As shown in Figure 6, taking the double-flared-curvature flow guides 111 numbered a and b as an example, the spacing L between the two relatively large-mouth ends of a and b is equal to 0.8-1.2 times the diameter φ of the large-mouth end of b. It has been verified that when the double-flared-curvature flow guides 111 are arranged at the above distance, the cold air flows more smoothly through the double-flared-curvature flow guides 111 without obvious blockage or interruption, and the process of drawing out the cold air is more stable.

[0097] As shown in FIG7 , as another embodiment of the present application, in a step-by-step decreasing flow guide unit 110, all dimensions of the five double-flared flow guide members 111 with gradually varying curvatures are identical except for the size of the central through hole. That is, the diameters of the large mouths of the five double-flared flow guide members 111 with gradually varying curvatures, i.e., a, b, c, d, and e, are identical in length, except for the diameter of the central through hole of a, which is larger than the diameter of the central through hole of b, which is larger than the diameter of the central through hole of c, which is larger than the diameter of the central through hole of d, which is larger than the diameter of the central through hole of e. Of course, in other embodiments, all dimensions of the five double-flared flow guide members 111 with gradually varying curvatures, except for the size of the central through hole, may also be different, as long as the diameters of the central through holes of the five double-flared flow guide members 111 with gradually varying curvatures decrease.

[0098] In the embodiment of the present application, the energy source 700 is a light source 710 , which is specifically a line light. Since the light source 710 is controllable and stable and does not require replacement or replenishment of consumables, it is an ideal energy source 700 .

[0099] As shown in Figure 8, the light source 710 includes a light-emitting portion 711 and an optical fiber 712. The light-entering surface of the optical fiber 712 is positioned opposite the light-emitting portion 711, and the light-emitting surface of the optical fiber 712 is positioned opposite the central through-hole of the corresponding gradient dual-horn flow guide. Due to the good guidance of the optical fiber 712, it can be guided in a specific direction, which helps improve the guidance of the cold air extraction process and make the extraction process more stable. Furthermore, a white crystal can be added between the light-emitting portion 711 and the optical fiber 712.

[0100] As shown in FIG2 , in this embodiment of the present application, the dual-flare flow guide members 111 with gradually decreasing curvature at both ends of the step-by-step flow guide unit 110 in the flow guide assembly 100 are respectively an input-end dual-flare flow guide member 112 and an output-end dual-flare flow guide member 113. The input-end dual-flare flow guide member 112 is larger than the output-end dual-flare flow guide member 113. That is, in this embodiment, a represents the input-end dual-flare flow guide member 112, and e represents the output-end dual-flare flow guide member 113. The light source 710 is disposed at one end of the flow guide assembly 100, i.e., on the side of e away from a. The light-emitting surface of the optical fiber 712 in the light source 710 faces the central through-hole of e. Furthermore, the centerline of the light-emitting surface of the optical fiber 712 is collinear with the central axis of e.

[0101] In this solution, the light is directed toward the output end double-horn body flow guide 113 with a gradual curvature change and toward the input end double-horn body flow guide 112 with a gradual curvature change (i.e., the direction of the human body), which can establish a connection with the cold air of the human body more quickly.

[0102] Regarding the fixing design of the light source 710 in the embodiment of the present application, the light source 710 can be fixed by adding a light source 710 fixing position in the base, or the light source 710 can be placed in the corresponding area in the guide assembly 100 by other clamping methods, which is not limited here.

[0103] Of course, in other embodiments, the energy source 700 may also be essential oil, moxa stick, or the like.

[0104] As an implementation method of the embodiment of the present application, the cold-dispelling device 10 only has a flow guide component 100 and an energy source 700, as shown in FIG9 . In this case, the method for using the cold-dispelling device 10 includes the following steps:

[0105] S1: Place one large opening of the double-flared flow guide with a gradual curvature at the input end opposite to the human body;

[0106] S2: Turn on the light source;

[0107] S3: Keep the body relatively still while removing the coldness from the device for a preset time.

[0108] Among them, the preset time is 10-30 minutes.

[0109] In this solution, during the use of the cold-removing device 10, the diversion component 100 does not move, and there is no need to add an additional moving component 800, which results in a smaller size and lower cost.

[0110] As another implementation of the embodiment of the present application, the cold-dispelling device 10 has, in addition to the flow guide component 100 and the energy source 700, a moving component 800, which drives the flow guide component 100 and the energy source 700 to move together. FIG10 is a schematic diagram of the moving component 800. As shown in FIG10 , the moving component 800 includes two parallel slide bars 810, a support frame 820 for fixing the slide bars 810, a mounting platform 830 that slides with the slide bars 810, and a control module that controls the mounting platform 830 to slide left and right on the slide bars 810. The control module includes a motor, a belt, etc., which are not shown one by one here. Among them, the flow guide component 100 and the energy source 700 are both fixed on the mounting platform 830.

[0111] Of course, in other embodiments, the moving assembly 800 may also adopt other designs, and it is only necessary to control the diversion assembly 100 and the energy source 700 to be able to move relative to the ground.

[0112] Correspondingly, as shown in FIG11 , the method for using the cold-removing device 10 includes the following steps:

[0113] S1: Place one large opening of the double-flared flow guide with a gradual curvature at the input end opposite to the human body;

[0114] S2: Turn on the light source;

[0115] S4: Keeping the diversion component and the human body relatively still for the first preset time;

[0116] S5: Control the diversion component to move a first preset distance away from the human body within the second preset time.

[0117] The first preset time is 5-30s, the second preset time is 150-250s, and the first preset distance is 50-200cm.

[0118] In this solution, during the use of the cold-removing device 10, by moving the guide component 100, the trend of drawing out the cold air can be made more obvious, further enhancing the effect of drawing out the cold air.

[0119] Example 2:

[0120] The second embodiment of the present application discloses a device for dispelling cold air. FIG12 is a schematic diagram of the flow guide assembly in the second embodiment of the present application. As shown in FIG12 , the device 10 for dispelling cold air in the present embodiment also includes a flow guide assembly 100 and an energy source 700. The flow guide assembly 100 also comprises five series-connected, dual-flared flow guide members 111 with gradually varying curvatures. The specific design is similar to that described in the first embodiment, and they are numbered a, b, c, d, and e. Similarly, a is the input-end, dual-flared flow guide member 112 with gradually varying curvatures, and e is the output-end, dual-flared flow guide member 113 with gradually varying curvatures. Furthermore, the energy source 700 in the present embodiment also utilizes a light source 710. However, unlike the first embodiment, the light source 710 in the present embodiment is located between the two elements e and d, and the light-emitting surface of the optical fiber 712 in the light source 710 faces the central through hole of element e.

[0121] In this solution, light is directed toward the double-horn body flow guide 113 with a gradual curvature at the output end, and irradiated away from the double-horn body flow guide 112 with a gradual curvature at the input end (i.e., the direction of the human body), which can guide the direction of the cold air extraction, allowing the cold air to be extracted along the direction of the light, thereby improving the guidance of the cold air extraction process and making the cold air extraction process more stable.

[0122] Of course, in other embodiments, the light source 710 can also be located between a and b, or between b and c, or between c and d. Furthermore, the cold-dispelling device 10 can include multiple light sources 710, each located between dual-flared flow guide members 111 with varying curvature gradients. For example, the cold-dispelling device 10 can include two light sources 710, one of which is located between c and d, with the light-emitting surface of the light source 710 facing the central through-hole of d; the other light source 710 is located between d and e, with the light-emitting surface of the light source 710 facing the central through-hole of e.

[0123] In the embodiment of the present application, the cold-removing device 10 can also be moved or not moved during use. Please refer to the description in the first embodiment for details and will not be repeated here.

[0124] Example 3:

[0125] The third embodiment of the present application discloses a device for dispelling cold air. Figure 13 is a schematic diagram of the diversion component in the third embodiment of the present application. As shown in Figure 13, the diversion component 100 in the embodiment of the present application is a series-decreasing diversion component 200. Different from the second embodiment, the diversion component 100 in the embodiment of the present application has two series-connected step-by-step decreasing diversion units 110, namely a main step-by-step decreasing diversion unit 210 and a secondary step-by-step decreasing diversion unit 220.

[0126] In the embodiment of the present application, the more curvature gradient dual-horn body guide pieces 111 are connected in series with the step-by-step decreasing guide unit 110, the higher the concentration of the cold air drawn out and the more stable the drawing-out process. However, when the smallest curvature gradient dual-horn body guide piece 111 remains unchanged and the ratio of the size enlargement remains unchanged, the length of the step-by-step decreasing guide unit 110 will increase, and the width and height will also increase. In order to reduce the volume, two step-by-step decreasing guide units 110 are used, and the number and size of the curvature gradient dual-horn body guide pieces 111 of the latter stage do not exceed those of the previous stage. In this way, when the total number of curvature gradient dual-horn body guide pieces 111 remains unchanged, the width and length of the product can be effectively controlled (i.e., the diameter of the largest curvature gradient dual-horn body guide piece 111 will not be too large), which is conducive to reducing the volume of the product.

[0127] The main step-by-step deflector unit 210 includes five serially connected dual-flared flow guide members 111 with gradually varying curvatures, numbered a, b, c, d, and e. Each of the five dual-flared flow guide members 111 is secured to a base and arranged sequentially in numbered order. The design of the main step-by-step deflector unit 210 can be specifically described in the description of the flow guide assembly 100 in the first embodiment and will not be repeated here.

[0128] The sub-step-by-step decreasing guide unit 220 includes three double-horn body guide members 111 with gradual curvature connected in series, numbered f, g, and h respectively. The three double-horn body guide members 111 with gradual curvature are all fixed on the corresponding bases and arranged in series in sequence along the order of numbers, so that the large mouth end of f is arranged opposite to the large mouth end of g, and the large mouth end of g is arranged opposite to the large mouth end of h.

[0129] In the secondary step-by-step deflection unit 220, the outline dimension of f is greater than the outline dimension of g, and the outline dimension of g is greater than the outline dimension of h. G and h are both proportionally scaled components of f. Specifically, g can be obtained by reducing f by 80%, and h can be obtained by reducing g by 80%. Of course, in actual applications, the reduction ratio can be between 60% and 90%.

[0130] Furthermore, in the secondary step-by-step decreasing flow guide unit 220, the central axes of f, g, and h are collinear. The spacing between the two opposing wide-opening ends of f and g is 0.8-1.2 times the diameter of g's wide-opening end, and the spacing between the two opposing wide-opening ends of h and g is 0.8-1.2 times the diameter of h's wide-opening end. The distance between the primary step-by-step decreasing flow guide unit 210 and the secondary step-by-step decreasing flow guide unit 220 is set to 0.5-2 times the diameter of f's wide-opening end.

[0131] In the guide assembly 100, the central axis of the main step-by-step decreasing guide unit 210 and the central axis of the secondary step-by-step decreasing guide unit 220 are on the same straight line, and the large mouth end f in the secondary step-by-step decreasing guide unit 220 faces the large mouth end e in the main step-by-step decreasing guide unit 210, and the outline size of a in the main step-by-step decreasing guide unit 210 is larger than the outline size of f in the secondary step-by-step decreasing guide unit 220.

[0132] Furthermore, the outline dimension h of the secondary step-by-step decreasing guide unit 220 is smaller than the outline dimension e of the primary step-by-step decreasing guide unit 210. Because the minimum central through hole determines the concentration of cold air, the minimum central through hole of the subsequent step-by-step decreasing guide unit 110 cannot exceed that of the previous stage, ensuring that the concentration of cold air does not decrease after multiple stages are connected in series.

[0133] In other embodiments, the serial decreasing air guide assembly 200 may also have three serially connected step-by-step decreasing air guide units 110 , and the number of the double-flared air guide members 111 with gradually varying curvature in the step-by-step decreasing air guide unit 110 may not be five or three.

[0134] In other embodiments, the multiple double-horn air guide members 111 with gradually changing curvatures in each step-by-step decreasing air guide unit 110 are not reduced in overall size, but only in the diameter of the central through hole. It is only necessary to ensure that the double-horn air guide member 111 with gradually changing curvatures having the largest diameter of the central through hole in the next step-by-step decreasing air guide unit 110 faces the double-horn air guide member 111 with the smallest diameter of the central through hole in the previous step-by-step decreasing air guide unit 110; the number of the double-horn air guide members 111 with gradually changing curvatures in the previous step-by-step decreasing air guide unit 110 is greater than the number of the double-horn air guide members 111 with gradually changing curvatures in the next step-by-step decreasing air guide unit 110; and the diameter of the largest central through hole in the previous step-by-step decreasing air guide unit 110 is greater than the diameter of the largest central through hole in the next step-by-step decreasing air guide unit 110. It can be understood that the previous stage gradually decreasing flow guide unit 110 is a gradually decreasing flow guide unit 110 that is closer to the user when the cold-removing air device 10 is in use.

[0135] In the embodiment of the present application, the energy source 700 also uses a light source 710, which is located between d and e of the main step-by-step decreasing guide unit 210, and the light-emitting surface of the optical fiber 712 in the light source 710 faces the central through hole of e.

[0136] In this solution, multiple step-by-step decreasing guide units 110 are connected in series, and the optical fiber 712 is set on the main step-by-step decreasing guide unit 210, close to the human body, which can better establish contact with the human body's cold air and stabilize the cold air extraction process.

[0137] Of course, in other embodiments, the light source 710 may also be placed between e and f, with the light emitting surface of the optical fiber 712 in the light source 710 facing the central through hole of e.

[0138] In other embodiments, a light source 710 may also be added to the secondary step-by-step decreasing guide unit 220, and the light source 710 may be placed between f and g so that the light-emitting surface of the light source 710 faces the central through hole of g; or the light source 710 may be placed between g and h so that the light-emitting surface of the light source 710 faces the central through hole of h.

[0139] In the embodiment of the present application, the base of the primary step-by-step decreasing flow guide unit 210 and the base of the secondary step-by-step decreasing flow guide unit 220 are not connected, so that the base of the primary step-by-step decreasing flow guide unit 210 and the base of the secondary step-by-step decreasing flow guide unit 220 are independent structures, which is convenient for carrying and assembly. Of course, in other embodiments, the base of the primary step-by-step decreasing flow guide unit 210 and the base of the secondary step-by-step decreasing flow guide unit 220 can also be connected together.

[0140] The cold-removing device 10 in the embodiment of the present application can also be moved or not moved during use. Please refer to the description in the first embodiment for details and will not be repeated here.

[0141] Example 4:

[0142] The fourth embodiment of the present application discloses a device for removing cold air. FIG14 is a schematic diagram of the guide assembly in the fourth embodiment of the present application. As shown in FIG14 , the guide assembly 100 in the embodiment of the present application is a gate-shaped guide assembly 300. The gate-shaped guide assembly 300 includes an input arm 310, a connecting arm 320 and an output arm 330. The input arm 310, the connecting arm 320 and the output arm 330 are connected end to end in sequence to form a In other words, the input arm 310 and the output arm 330 are arranged in parallel, and the connecting arm 320 is located between the input arm 310 and the output arm 330 and is arranged perpendicular to the input arm 310 and the output arm 330 .

[0143] Among them, the spacing between the input arm 310 and the connecting arm 320 is 10mm-50mm, the spacing between the output arm 330 and the connecting arm 320 is 10mm-50mm, and in the input arm 310, the connecting arm 320 and the output arm 330, the spacing between any two adjacent curvature gradient double horn body guide parts 111 is between 10mm-50mm.

[0144] After the cold air is drawn out, the body will feel empty. It takes a long time for the body to generate positive energy to fill the empty space, which is inefficient. Arranged in a Chinese character, the tail portion of the step-by-step descending flow guide unit 110 of the input arm 310 (the section of the double-horn flow guide 111 with the smallest curvature at the center through hole) is adjacent to the head portion of the step-by-step descending flow guide unit 110 of the connecting arm 320 (the section of the double-horn flow guide 111 with the smallest curvature at the center through hole), and the two are arranged perpendicularly. The cold air from the input arm 310 diffuses into the external space; because the cold air is relatively turbid and stagnant, most of it does not directly enter the connecting arm 320. However, the external environment itself contains positive energy, which is relatively clear and flowing, so a small portion of the cold air enters the connecting arm 320 with the positive energy, forming a primary filtration. Similarly, only a small portion of the cold air from the connecting arm 320 enters the input arm 310, forming a secondary filtration. The filtered air, which is mainly positive energy, is reintroduced into the human body through the output arm 330. This achieves the exchange of cold air in the human body and positive energy from the outside world. While the cold air in the human body is reduced, the positive energy can be replenished in a timely manner, greatly improving the replenishment efficiency of positive energy.

[0145] In the gate-shaped flow guide assembly 300, the input arm 310, the connecting arm 320, and the output arm 330 each have only one step-by-step decreasing flow guide unit 110. The step-by-step decreasing flow guide unit 110 in the input arm 310 has five double-horn flow guide pieces 111 with gradually varying curvatures connected in series. The five double-horn flow guide pieces 111 with gradually varying curvatures are numbered a1, b1, c1, d1, and e1, respectively. The step-by-step decreasing flow guide unit 110 in the connecting arm 320 has five double-horn flow guide pieces 111 with gradually varying curvatures connected in series. The five double-horn flow guide pieces 111 with gradually varying curvatures are numbered a2, b2, c2, d2, and e2, respectively. The step-by-step decreasing flow guide unit 110 in the connecting arm 320 also has five double-horn flow guide pieces 111 with gradually varying curvatures connected in series. The five double-flared flow guide members 111 with gradually varying curvatures are numbered a3, b3, c3, d3 and e3 respectively.

[0146] Moreover, no matter in which step-by-step decreasing guide unit 110, the curvature gradient double-horn body guide member 111 is connected in series in sequence from a to e, and along the direction from a to e, the outline size of the curvature gradient double-horn body guide member 111 gradually decreases, and the design of each step-by-step decreasing guide unit 110 can refer to the description of the step-by-step decreasing guide unit 110 in the first embodiment, and will not be repeated here.

[0147] In the embodiment of the present application, a2 in the connecting arm 320 is close to e1 in the input arm 310 , and e2 in the connecting arm 320 is close to a3 in the output arm 330 .

[0148] In the embodiment of the present application, the central axes of the input arm 310 , the connecting arm 320 , and the output arm 330 are in the same plane.

[0149] In the embodiment of the present application, the cold-dispelling device 10 may not have the light source 710. Of course, the cold-dispelling device 10 may also have the light source 710, which is located between d1 and e1 of the input arm 310, and the light-emitting surface of the optical fiber 712 in the light source 710 faces the central through hole of e1.

[0150] As a further implementation of the embodiment of the present application, the diameter of the central through hole of a1 in the input arm 310 is larger than the diameter of the central through hole of a2 in the connecting arm 320, and the diameter of the central through hole of e1 in the input arm 310 is larger than the diameter of the central through hole of e2 in the connecting arm 320; the diameter of the central through hole of a2 in the connecting arm 320 is larger than the diameter of the central through hole of a3 in the output arm 330, and the diameter of the central through hole of e2 in the connecting arm 320 is larger than the diameter of the central through hole of e3 in the output arm 330.

[0151] Of course, in other embodiments, the sizes of the three gradually decreasing flow guiding units 110 in the input arm 310 , the connecting arm 320 , and the output arm 330 may remain consistent.

[0152] The cold-removing device 10 in the embodiment of the present application can also be moved or not moved during use. Please refer to the description in the first embodiment for details and will not be repeated here.

[0153] Embodiment 5:

[0154] The fifth embodiment of the present application discloses a device for dispelling cold air. Figure 15 is a schematic diagram of the guide assembly in the fifth embodiment of the present application. As shown in Figure 15, the guide assembly 100 in the embodiment of the present application is also a gate-shaped guide assembly 300, and there is only one step-by-step decreasing guide unit 110 in the input arm 310 and the output arm 330, and the step-by-step decreasing guide unit 110 also has five series-connected double-horn guide members 111 with gradually changing curvatures, that is, the five double-horn guide members 111 with gradually changing curvatures in the input arm 310 are numbered a1, b1, c1, d1 and e1 respectively, and the five double-horn guide members 111 with gradually changing curvatures in the output arm 330 are numbered a3, b3, c3, d3 and e3 respectively.

[0155] However, unlike the fourth embodiment, the connecting arm 320 in the embodiment of the present application has two step-by-step decreasing guide units 110, namely the first step-by-step decreasing guide unit 110 and the second step-by-step decreasing guide unit 110, wherein the first step-by-step decreasing guide unit 110 has five double-horn guide members 111 with a gradual curvature connected in series, and the five double-horn guide members 111 with a gradual curvature are numbered a2, b2, c2, d2 and e2 respectively; the second step-by-step decreasing guide unit 110 has three double-horn guide members 111 with a gradual curvature connected in series, and the three double-horn guide members 111 with a gradual curvature are numbered f2, g2 and h2 respectively.

[0156] Among them, whether it is the first step-by-step decreasing guide unit 110 or the second step-by-step decreasing guide unit 110, the central through-hole diameters of the curvature gradient double-horn body guide parts 111 are arranged in alphabetical order, and the central axes of the first step-by-step decreasing guide unit 110 and the second step-by-step decreasing guide unit 110 are located on the same straight line. The design of the connecting arm 320 can specifically refer to the design of the main step-by-step decreasing guide unit 210 and the auxiliary step-by-step decreasing guide unit 220 in the third embodiment, and will not be described one by one here. In the embodiment of the present application, the number of curvature gradient double-horn body guide parts 111 in the connecting arm 320 is greater than the number of curvature gradient double-horn body guide parts 111 in the input arm 310; and the number of curvature gradient double-horn body guide parts 111 in the input arm 310 is equal to the number of curvature gradient double-horn body guide parts 111 in the output arm 330. The number of double-horn flow guides 111 with a gradual curvature of the connecting arm 320 exceeds that of the input arm 310, which increases the attraction to the input arm 310 and can further stabilize the process of drawing out the cold air; the number of double-horn flow guides 111 with a gradual curvature of the input arm 310 and the output arm 330 is the same, which can maintain a balance between the drawn-out cold air and the supplemented positive energy.

[0157] Furthermore, the connecting arm 320 is formed by two serially connected progressively decreasing flow guide units 110. The latter progressively decreasing flow guide unit 110 utilizes three serially connected dual-flared flow guide members 111 with gradually varying curvatures. This satisfies the requirement for cold air guidance without requiring movement. Using fewer dual-flared flow guide members 111 with gradually varying curvatures enhances the cold air guidance effect, helping to reduce costs and product size. Furthermore, a2 within the first progressively decreasing flow guide unit 110 is adjacent to e1 within the input arm 310. e2 within the first progressively decreasing flow guide unit 110 faces f2 within the second progressively decreasing flow guide unit 110. H2 within the second progressively decreasing flow guide unit 110 is adjacent to a3 within the output arm 330.

[0158] Of course, in other embodiments, the input arm 310 and the output arm 330 may have more than one gradually decreasing flow guide unit 110. However, preferably, the input arm 310 and the output arm 330 have the same number of gradually decreasing flow guide units 110 and the same number of gradually changing double-flared flow guide members 111, with corresponding shapes and sizes. Similarly, the connecting arm 320 may have more than two gradually decreasing flow guide units 110, and may also have a configuration other than the first gradually decreasing flow guide unit 110 having five gradually changing double-flared flow guide members 111 and the second gradually decreasing flow guide unit 110 having three gradually changing double-flared flow guide members 111. The selection will depend on the actual situation.

[0159] Example 6:

[0160] The sixth embodiment of the present application discloses a device for dispelling cold air. FIG16 is a perspective schematic diagram of the guide assembly in the sixth embodiment of the present application, and FIG17 is a side schematic diagram of the guide assembly in the sixth embodiment of the present application. As shown in FIG16 and FIG17, the guide assembly 100 in the embodiment of the present application is a three-dimensional guide assembly 400, which has four step-by-step decreasing guide units 110, namely a third step-by-step decreasing guide unit 410, a fourth step-by-step decreasing guide unit 420, a fifth step-by-step decreasing guide unit 430, and a sixth step-by-step decreasing guide unit 440. Among them, the third step-by-step decreasing guide unit 410, the fourth step-by-step decreasing guide unit 420, the fifth step-by-step decreasing guide unit 430, and the sixth step-by-step decreasing guide unit 440 are all step-by-step decreasing guide units 110 having five double-flared guide members 111 with gradually varying curvatures, and the corresponding double-flared guide members 111 with gradually varying curvatures have the same shape and size.

[0161] For ease of understanding, the embodiments of the present application are illustrated as follows: the five double-horn body air guide members 111 with gradually varying curvatures in the third step-by-step decreasing air guide unit 410 are numbered a1, b1, c1, d1 and e1 in series order, the five double-horn body air guide members 111 with gradually varying curvatures in the fourth step-by-step decreasing air guide unit 420 are numbered a2, b2, c2, d2 and e2 in series order, the five double-horn body air guide members 111 with gradually varying curvatures in the fifth step-by-step decreasing air guide unit 430 are numbered a3, b3, c3, d3 and e3 in series order, and the five double-horn body air guide members 111 with gradually varying curvatures in the sixth step-by-step decreasing air guide unit 440 are numbered a4, b4, c4, d4 and e4 in series order. As for the outline dimensions of the five double-horn body air guide members 111 with gradually varying curvatures in the step-by-step decreasing air guide unit 110, they also decrease in alphabetical order.

[0162] The design of each step-by-step decreasing flow guiding unit 110 may refer to the description of the step-by-step decreasing flow guiding unit 110 in the first embodiment, and will not be repeated here.

[0163] The central axes of the third, fourth, fifth, and sixth step-by-step decreasing flow guiding units 410, 420, 430, and 440 are parallel. The central axes of the third, fourth, and fifth step-by-step decreasing flow guiding units 410, 420, and 430 enclose an equilateral triangle-shaped region, with the central axis of the sixth step-by-step decreasing flow guiding unit 440 located at the center of the region. Specifically, the spacing between the central axis of the sixth step-by-step decreasing flow guiding unit 440 and the central axis of the third step-by-step decreasing flow guiding unit 410 is equal to the spacing between the central axis of the sixth step-by-step decreasing flow guiding unit 440 and the central axis of the fourth step-by-step decreasing flow guiding unit 420, and is equal to the spacing between the central axis of the sixth step-by-step decreasing flow guiding unit 440 and the central axis of the fifth step-by-step decreasing flow guiding unit 430. Furthermore, the wide-mouthed ends of the double-flared flow guide members 111 with the largest central through-holes in the third, fourth, and fifth step-by-step decreasing flow guide units 410, 420, and 430 are located in the same plane, while the wide-mouthed ends of the double-flared flow guide members 111 with the largest central through-holes in the sixth step-by-step decreasing flow guide unit 440 are retracted relative to the plane, and the wide-mouthed ends of the double-flared flow guide members 111 with the largest central through-holes in the sixth step-by-step decreasing flow guide unit 440 are outside the plane. It is understood that the aforementioned "retracted" means that, relative to the other three step-by-step decreasing flow guide units 110, the sixth step-by-step decreasing flow guide unit 440 is moved a certain distance along the central axis toward the wide-mouthed end away from a1 before being fixed.

[0164] Alternatively, the wide ends of the three gradually-varying-curvature dual-flared flow guides 111 (a1, a2, and a3) are located in the same plane, while the wide end of the gradually-varying-curvature dual-flared flow guide 111 (a4) is located between a1 and e1. Specifically, the wide end of a4 can be located in the gap between a1 and b1. In this case, a1, a2, a3, and a4 are located at the four endpoints of a regular triangular pyramid, or in other words, the four points a1, a2, a3, and a4 form a regular triangular pyramid.

[0165] In this embodiment of the present application, the wide-mouthed end of the gradually-decreasing dual-flare flow guide 111 with the largest central through-hole within the sixth progressively decreasing flow guide unit 440 is positioned outside the plane and indented toward the gradually-decreasing dual-flare flow guide 111 with the smallest central through-hole. This creates a three-dimensional cold air convergence surface at the input ends of the four progressively decreasing flow guide units 110, similar to the smoke inlet of a chimney. This significantly enhances the cold air convergence capability and improves the efficiency of cold air extraction. Furthermore, the four progressively decreasing flow guide units 110 are of equal size and number, allowing for evenly distributed cold air and enhancing the stability of the cold air extraction process.

[0166] In an embodiment of the present application, there are four light sources 710, and the four light sources 710 are respectively located at the tail ends of the four step-by-step decreasing guide units 110, that is, there is a light source 710 at the end away from a1 of the four double-horn body guide parts 111 with gradual curvature, namely e1, e2, e3 and e4, and the light-emitting surfaces of the optical fibers 712 in the four light sources 710 correspond to the central through holes of the four double-horn body guide parts 111 with gradual curvature, namely e1, e2, e3 and e4.

[0167] The light is directed toward the output-end double-horn-body flow guide 113 with a gradual curvature change and toward the input-end double-horn-body flow guide 112 with a gradual curvature change (i.e., the direction of the human body), which can establish a connection with the cold air of the human body more quickly.

[0168] The cold-removing device 10 in the embodiment of the present application can also be moved or not moved during use. Please refer to the description in the first embodiment for details and will not be repeated here.

[0169] Embodiment seven:

[0170] The seventh embodiment of the present application discloses a device for dispelling cold air. Figure 18 is a schematic diagram of the guide component in the seventh embodiment of the present application. As shown in Figure 18, the guide component 100 in the embodiment of the present application adopts the same design as the guide component 100 in the seventh embodiment, but the difference is that the four light sources 710 in the embodiment of the present application are respectively located inside the four step-by-step decreasing guide units 110, that is, the four light sources 710 are respectively located between d1 and e1, between d2 and e2, between d3 and e3, and between d4 and e4, and the light-emitting surfaces of the optical fibers 712 in the four light sources 710 correspond to the central through holes of the four double-horn guide components 111 with gradually varying curvatures, namely e1, e2, e3 and e4.

[0171] In an embodiment of the present application, light is irradiated toward the double-horn body flow guide 113 with a gradual curvature at the output end and away from the double-horn body flow guide 112 with a gradual curvature at the input end (i.e., the direction of the human body), which can guide the direction of the cold air discharge, allowing the cold air to be discharged along the direction of the light, thereby improving the guidance of the cold air discharge process and making the cold air discharge process more stable.

[0172] Embodiment 8:

[0173] The eighth embodiment of the present application discloses a device for dispelling cold air. FIG19 is a schematic diagram of the diversion assembly in the eighth embodiment of the present application. As shown in FIG19 , the diversion assembly 100 in the embodiment of the present application is also a three-dimensional diversion assembly 400. However, unlike the seventh embodiment, the three-dimensional diversion assembly 400 in the embodiment of the present application includes two three-dimensional step-by-step decreasing diversion modules 500, namely a first three-dimensional step-by-step decreasing diversion module 510 and a second three-dimensional step-by-step decreasing diversion module 520. The first three-dimensional step-by-step decreasing diversion module 510 and the second three-dimensional step-by-step decreasing diversion module 520 both have four step-by-step decreasing diversion units 110. The first three-dimensional step-by-step decreasing diversion module 510 and the second three-dimensional step-by-step decreasing diversion module 520 can be specifically referred to the description of the three-dimensional diversion assembly 400 in the sixth embodiment, which will not be repeated here.

[0174] The embodiment of the present application uses two three-dimensional step-by-step decreasing guide modules 500 connected in series. Compared with a single three-dimensional step-by-step decreasing guide module 500 with the same number of double-horn guide members 111 with gradually changing curvature, the volume of the product can be reduced while the cold air guiding effect is basically the same.

[0175] The number of dual-flared air guide members 111 with gradually varying curvatures in the step-by-step decreasing air guide units 110 in the first three-dimensional step-by-step decreasing air guide module 510 is greater than the number of dual-flared air guide members 111 with gradually varying curvatures in the step-by-step decreasing air guide units 110 in the second three-dimensional step-by-step decreasing air guide module 520. Specifically, each step-by-step decreasing air guide unit 110 in the first three-dimensional step-by-step decreasing air guide module 510 has five dual-flared air guide members 111 with gradually varying curvatures, and each step-by-step decreasing air guide unit 110 in the second three-dimensional step-by-step decreasing air guide module 520 has three dual-flared air guide members 111 with gradually varying curvatures.

[0176] In an embodiment of the present application, the first three-dimensional step-by-step decreasing flow diversion module 510 and the second three-dimensional step-by-step decreasing flow diversion module 520 are arranged in series, and the central axes of the first three-dimensional step-by-step decreasing flow diversion module 510 and the second three-dimensional step-by-step decreasing flow diversion module 520 are on the same straight line. The central axes of the four step-by-step decreasing flow diversion units 110 in the first three-dimensional step-by-step decreasing flow diversion module 510 are on the same straight line with the central axes of the corresponding step-by-step decreasing flow diversion units 110 in the second three-dimensional step-by-step decreasing flow diversion module 520.

[0177] In the embodiment of the present application, the end of the smaller dual-flare flow guide member 111 with a gradually changing curvature in the first three-dimensional step-by-step decreasing flow guide module 510 is disposed in front of the end of the larger dual-flare flow guide member 111 with a gradually changing curvature in the second three-dimensional step-by-step decreasing flow guide module 520. The specific design between each step-by-step decreasing flow guide unit 110 in the first three-dimensional step-by-step decreasing flow guide module 510 and each step-by-step decreasing flow guide unit 110 in the second three-dimensional step-by-step decreasing flow guide module 520 can be referred to the description of the serially decreasing flow guide assembly 200 in the third embodiment and will not be repeated here.

[0178] Similarly, the curvature gradient double-horn body guide pieces 111 at both ends of each step-by-step decreasing guide unit 110 are respectively an input end curvature gradient double-horn body guide piece 112 and an output end curvature gradient double-horn body guide piece 113, and the size of the input end curvature gradient double-horn body guide piece 112 is larger than the size of the output end curvature gradient double-horn body guide piece 113.

[0179] In the embodiment of the present application, there are also four light sources 710, and the optical fibers 712 of the four light sources 710 are respectively located between the output-end curvature gradient double-horn body guide piece 113 and the adjacent curvature gradient double-horn body guide piece 111 in the four step-by-step decreasing guide units 110 of the first three-dimensional step-by-step decreasing guide module 510, and the light-emitting surfaces of the four optical fibers 712 are respectively facing the central through holes of the four output-end curvature gradient double-horn body guide pieces 113.

[0180] The optical fiber 712 is arranged on the first three-dimensional step-by-step decreasing guide module 510, close to the human body, and can better establish a connection with the human body's cold air and stabilize the process of drawing out the cold air.

[0181] In other embodiments, the three-dimensional flow guide assembly 400 may further include more three-dimensional step-by-step decreasing flow guide modules 500 connected in series.

[0182] Embodiment 9:

[0183] The ninth embodiment of the present application discloses a device for removing cold air. FIG20 is a schematic diagram of the diversion assembly in the ninth embodiment of the present application. As shown in FIG20 , the diversion assembly 100 in the embodiment of the present application is a door-shaped three-dimensional diversion assembly 600. The door-shaped three-dimensional diversion assembly 600 includes a three-dimensional input arm 610, a three-dimensional connecting arm 620 and a three-dimensional output arm 630. The three-dimensional input arm 610, the three-dimensional connecting arm 620 and the three-dimensional output arm 630 are connected end to end in sequence to form a The stereo input arm 610 and the stereo output arm 630 are arranged in parallel, and the stereo connecting arm 620 is located between the stereo input arm 610 and the stereo output arm 630 and is arranged perpendicular to the stereo input arm 610 and the stereo output arm 630.

[0184] The embodiment of the present application adopts a three-dimensional step-by-step decreasing diversion module 500 to form The glyph-shaped guide component 100 can further improve the efficiency of drawing out cold air and replenishing positive energy.

[0185] The three-dimensional input arm 610 and the three-dimensional output arm 630 each include a three-dimensional step-by-step decreasing flow diversion module 500. The specific design of the three-dimensional input arm 610 and the three-dimensional output arm 630 may refer to the three-dimensional flow diversion assembly 400 of the sixth embodiment. The three-dimensional connecting arm 620 includes two three-dimensional step-by-step decreasing flow diversion modules 500 connected in series. The specific design of the three-dimensional connecting arm 620 may refer to the three-dimensional flow diversion assembly 400 of the eighth embodiment, and will not be described in detail here.

[0186] Among them, the double-horn body flow guide 111 with a gradual curvature and the largest central through hole in the three-dimensional connecting arm 620 is close to the double-horn body flow guide 111 with a gradual curvature and the smallest central through hole in the three-dimensional input arm 610; the double-horn body flow guide 111 with a gradual curvature and the smallest central through hole in the three-dimensional connecting arm 620 is close to the double-horn body flow guide 111 with a gradual curvature and the largest central through hole in the three-dimensional output arm 630.

[0187] For the design of the corresponding step-by-step decreasing guide units 110 in the three-dimensional input arm 610, the three-dimensional connecting arm 620 and the three-dimensional output arm 630, please refer to the description of the gate-shaped guide assembly 300 in the fourth embodiment, which will not be repeated here.

[0188] In the embodiment of the present application, the cold-removing device 10 may not have the light source 710 .

[0189] The present application also provides the following clinical data to prove the technical effects claimed in the present application:

[0190] First, 30 women with cold constitution who felt cold soles of their feet before going to bed were selected and randomly divided into three groups of 10 people each.

[0191] The inclusion criteria were as follows: ① Women who feel cold feet before going to bed in daily life; ② Those who meet one or more of the following cold constitution criteria: moderate or slightly fat body shape, but weak and easily fatigued; pale and dull complexion; small appetite, average digestion and absorption function; usually afraid of cold and preferring heat, or low body temperature; pale and pale lips and tongue, slow pulse, introverted personality, preferring quiet and less movement, or timid and easily startled; weak energy, slow movements, slow reaction, and low libido; ③ Age 35 to 70 years old; ④ Signed informed consent form; ⑤ Those who can provide detailed contact information, have no intention of short-term migration, and are willing to cooperate with follow-up.

[0192] The following conditions were excluded: ① Those with a history of chronic diseases such as heart disease, hypertension, and diabetes, as well as acute illnesses, infectious diseases, and malignant tumors; ② Those with current pain due to other causes; ③ Those with severe mental or psychological illnesses; ④ Those with plantar ulcers or wounds; ⑤ Pregnant or breastfeeding women; ⑥ Those with a history of alcohol or drug abuse; ⑦ Those currently participating in other clinical studies; and ⑧ Those unable to cooperate with follow-up. Patients meeting any of the above criteria were not included in the study.

[0193] Next, the subjects were grouped. Specifically, each subject was assigned a random number between 1 and 99 by a computer. The random numbers were arranged from largest to smallest. The ten subjects with the smallest numbers were assigned to the three-level descending group, the ten subjects with the middle numbers were assigned to the two-level descending group, and the ten subjects with the largest numbers were assigned to the blank control group.

[0194] The three-level gradually decreasing group adopts the cold-dispelling air equipment of the present application (hereinafter referred to as equipment 1). The cold-dispelling air equipment adopts a gradually decreasing guide unit. The gradually decreasing guide unit includes three double-horn guide parts with a gradient curvature of the same shape and decreasing size. The energy source adopts optical fiber. The optical fiber is arranged behind the last double-horn guide part with a gradient curvature of the gradually decreasing guide unit, and the light-emitting surface of the optical fiber faces the human body.

[0195] The two-stage progressive reduction group used Device 2. Device 2 was based on Device 1, but with the last dual-flare deflector with a gradient curvature removed, retaining the first two. Its outer shell was identical to Device 1, making it indistinguishable from the outside. The blank control group used Device 3, a sham instrument with an identical outer shell to Devices 1 and 2 but a hollow interior.

[0196] The experimental process of the three groups of subjects was the same. The specific experimental process is as follows:

[0197] Have the subject lie flat and relax. Place Devices 1, 2, and 3 approximately 20-30 cm from the sole of their foot. Align the input port marked on the device housing (i.e., the largest end of the dual-flare, curvature-varying diverter on Device 1) with the sole of the subject's foot. Then, have the subject lie still for 20 minutes.

[0198] All three groups received the treatment once a day for seven consecutive days.

[0199] After the experiment, the subjects' feelings were mainly observed for seven days. The results were as follows: markedly effective: the soles of the feet felt warm or no longer cold before bed; effective: the soles of the feet felt better than before; ineffective: the soles of the feet felt no better or even worse. The specific results are as follows:

[0200] The results showed that in the three-step desensitization group, 7 patients showed marked efficacy, 3 patients showed effective efficacy, and the total effective rate reached 100%. In the two-step desensitization group, 1 patient showed marked efficacy, 2 patients showed effective efficacy, and 7 patients showed no efficacy, for a total effective rate of 30%. In the blank control group, 1 patient showed effective efficacy, 9 patients showed no efficacy, for a total effective rate of 10%. See the table below for details.

[0201] It can be clearly seen from the above table that the use of a three-stage gradually decreasing symmetrical diversion component can significantly alleviate the coldness of the soles of the feet of people with cold constitution before going to bed, and the effect is obvious; while the use of a two-stage gradually decreasing symmetrical diversion component can only achieve a certain effect on some subjects, and the effect is not ideal.
