[0001] The present application relates to the technical field of health care equipment, and in particular to a device for removing cold. Background Art

[0002] Many diseases we see in life, such as frozen shoulder and old cold legs, often manifested by joint pain, limited movement and other symptoms, are caused by the invasion of cold air into the human body. At present, there is no other objective and easy-to-operate method to expel cold air from the human body. Therefore, there is an urgent need for an objective and easy-to-operate device and its use method that can expel cold air from the human body. Utility Model Content

[0003] The purpose of this application is to provide an objective and easy-to-operate device for removing cold air from the human body.

[0004] The present application discloses a device for dispelling cold air, which includes a mobile component, an energy source fixing structure, a flow diversion module and a control module. The energy source fixing structure is arranged on the mobile component and is used to fix the energy source; the flow diversion module is arranged on the mobile component, and both ends of the flow 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 flow diversion module to move in a direction away from the user to be dispelled cold air.

[0005] Optionally, the diversion module includes at least a first speaker and a second speaker, the large mouth end of the first speaker faces the energy source fixed structure, and the large mouth end of the second speaker faces the user to be dispelled cold; the first speaker and the second speaker form the channel; the large mouth end of the first speaker faces the energy source fixed structure, and the large mouth end of the second speaker faces the user to be dispelled cold; the first speaker includes a large mouth end and a small mouth end, and the second speaker includes a large mouth end and a small mouth end, the diameter of the large mouth end of the first speaker is greater than the diameter of the small mouth end of the first speaker, and the diameter of the large mouth end of the second speaker is greater than the diameter of the small mouth end of the second speaker. This scheme includes at least one first speaker and one second speaker, and the two large mouth ends of the formed channel face the human body and the energy source respectively, so that after the human body cold air gathers in the channel of the first speaker, it is guided through the channel of the second speaker and diffused toward the energy source; this diffusion process will further amplify the guiding effect of the cold air, attract more cold air to pass through the first speaker, that is, the cold air will be accelerated after passing through the first speaker, and then drive more cold air to enter the first speaker at an accelerated speed, greatly improving the efficiency of cold air extraction, and even extracting deeper cold air from the human body.

[0006] Optionally, the flow guide 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 arc lines along the section lines on the central axis, and the arc lines are concave toward the central axis. In this solution, the inner walls of the first speaker and the second speaker adopt concave arc surfaces, and 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, so that the entire cold air guiding process tends to be smooth, and the cold air can establish a more stable connection with the energy source.

[0007] Optionally, the section line of the inner wall of the first horn and the second horn along the central axis is an arc line, and the curvature of the arc line 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 of the first horn and the second horn.

[0008] Optionally, the tangent of the endpoint of the wide mouth end of the first horn corresponding to the arc is perpendicular or tends to be perpendicular to the central axis, and the tangent of the endpoint of the wide mouth end of the second horn corresponding to the arc is perpendicular or tends to be perpendicular to the central axis, that is, the wide 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 effect of guiding the cold air, the wide mouth end can cover the cold air emitted from the human body as much as possible, and the guiding effect is better.

[0009] Optionally, the diversion module is a nested diversion component, one end of the nested diversion component is facing the energy source fixed structure, and the other end of the nested diversion component is facing the user to be rid of cold air; the nested diversion component includes at least two levels of curvature gradient double-horn body diversion parts, the sizes of different levels of curvature gradient double-horn body diversion parts are different, and the curvature gradient double-horn body diversion parts of the lower level are nested in the curvature gradient double-horn body diversion parts of the upper level; the channel of the curvature gradient double-horn body diversion part is double-horn shaped, with the channel extension direction as the central axis, presenting an axially symmetrical structure; 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 first horn includes a large mouth end and a small mouth end. The two horns include 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 previous level and the double-horn body guide member with gradual curvature at the next level at the narrowest part of the channel at least partially overlap.

[0010] In the present scheme, 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 previous 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 next 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 previous level enters the small-sized curvature gradient double-horn body guide piece (the curvature gradient double-horn body guide piece of the next level), through secondary guidance, it can enhance the attraction of the cold air and allow 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 next level is narrower, which can make the cold air more concentrated. After adopting the nested guide assembly, the attraction formed by at least two guides 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 and 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.

[0011] Optionally, the mobile component includes a frame, wheels, a motor and a mounting platform; the wheels are fixed to the frame, and the motor drives the wheels to rotate; the control module is arranged on the frame, and is used to control the running direction, running speed and running time of the motor; the mounting platform is arranged on the frame, and the energy source fixing structure and the diversion module are fixed on the mounting platform.

[0012] Optionally, the moving component includes a sliding rod assembly, a support frame and an installation platform, the sliding rod assembly includes a sliding rod, the sliding rod is fixed on the support frame and suspended in the air to form a track, the installation platform is arranged on the track, the energy source fixing structure and the guide module are both fixed to the installation platform and move on the track with the installation platform.

[0013] Optionally, the energy source comprises one or more of moxa products, essential oils or light sources.

[0014] After waiting for a first preset time, the control module drives the mobile component to drive the energy source fixed structure and the diversion module to move a first preset distance away from the user to be rid of cold; the first preset time is 10-300s, and the first preset distance is 50-200cm; the control module drives the mobile component to drive the energy source fixed structure and the diversion module to move the first preset distance away from the user to be rid of cold at a uniform speed of 2-5mm / s.

[0015] According to this scheme, after an energy source such as moxa sticks is aimed at a user to be cured of cold at a close distance, 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. Then the diversion module and the energy source are 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.

DETAILED DESCRIPTION

[0046] 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, but the present application can be implemented in many alternative forms and should not be construed as being limited to only the embodiments described herein.

[0047] The present application is described in detail below with reference to the accompanying drawings and optional embodiments.

[0048] like Figure 1 As shown, the present application provides a device 10 for removing cold air, which includes a mobile component 100, an energy source fixing structure 200, a flow guide module 300 and a control module 400. The energy source fixing structure 200 is arranged on the mobile component 100, and is used to fix the energy source 600; the flow guide module 300 is arranged on the mobile component 100, and both ends of the flow guide 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 removed from the cold; 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 flow guide module 300 to move in a direction away from the user to be removed from the cold.

[0049] The inventor has found that although people know about sparrow pecking moxibustion, they do not know enough about the principle of sparrow pecking moxibustion. The inherent view is to first bring the moxa close to the human body part, and then quickly pull it out in a similar way to pulling out a plug, so as to lead the cold to escape, and pull out a little at a time, so it is necessary to release the cold in succession many times. With the technique of sparrow pecking moxibustion, there is no consciousness of stopping when the energy source 600 approaches the user to be relieved of cold. It mainly relies on the connection established by the moxa stick in the process of approaching the user to be relieved of cold. The sparrow pecking moxibustion is also relatively fast when approaching, and there is no conscious stop, resulting in an unstable connection. Therefore, in the process of pulling out, if the speed is slow, it is easy to break. On the contrary, it is pulled out quickly to bring out a certain amount of cold before the connection is broken, resulting in the cold brought out each time the plug is pulled out is quite limited, and it must be repeated many times to have 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.

[0050] After the energy source such as moxa stick is aimed at the user to be cured of cold at a close distance, the scheme allows the energy source to establish a more stable connection with the cold air by waiting for a first preset time, and then a diversion module 300 is added to further improve the stability of the connection between the energy source 600 and the cold air of the user to be cured of cold. Then the diversion module 300 and the energy source 600 are 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 the direction away from the user to be cured of cold, the connection between the cold air and the energy source 600 is relatively not easy to break. Through a moving process, that is, during the use of the cold-dispelling device 10, the energy source fixed structure 200 and the diversion module 300 only move in the direction away from the user to be cured of cold, and do not return. The energy source 600 and the diversion module 300 do not move in the direction of the user to be cured of cold, so that the cold air can be continuously led out of the body, and the efficiency of cold air leading out is significantly better than the existing sparrow pecking moxibustion. It is also more objective and easier to operate.

[0051] In this solution, the control module 400 controls the moving component 100 to drive the energy source 600 and the diversion module 300 to move, replacing manual work. During the movement, the device can run accurately according to the set program. The operation process is stable and reliable. When moving away from the user to be removed from the cold, it is not easy to cause the connection between the cold and the energy source 600 to be disconnected. The cold of the user to be removed from the cold can be continuously led out, thereby achieving the effect of removing 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.

[0052] like Figure 2As shown, the flow guide 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 includes a large mouth end 310a1 and a small mouth end 310b1, and the second speaker includes a large mouth end 310a2 and a small mouth end 310b2. The diameter of the large mouth end 310a1 of the first speaker is larger than the diameter of the small mouth end 310b1 of the first speaker, and the diameter of the large mouth end 310a2 of the second speaker is larger than the diameter of the small mouth end 310b2 of the second speaker. When the flow guide module is used, the large mouth end 310a1 of the first speaker 311 faces the energy source fixing structure 200, and the large mouth end 310a2 of the second speaker 312 faces the user to be dispelled 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.

[0053] In this way, the human body's cold air 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, attract more cold air 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 accelerate into the first speaker 311, greatly improving the efficiency of the cold air extraction. During the verification process, the inventor also found that after adopting the double-horn-shaped channel structure, users generally reported that deeper cold air can be drawn out. According to the inventor's analysis, the cold air inside the human body is intertwined. When the attraction is large enough, it can drive the deep cold air to transfer to the surface, and finally lead it 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 deeper cold air of the human body.

[0054] Secondly, the first speaker 311 and the second speaker 312 are arranged axially symmetrically. With a symmetrical double speaker structure, the second speaker 312 and the first speaker 311 are matched in their ability to gather cold air, and the process of leading out cold air during movement is consistent, and the connection between cold air and energy source 600 is more stable and not easily interrupted. If there is inconsistency, two situations will occur: when the guiding ability of the channel of the second speaker 312 exceeds the channel of the first speaker 311, the guiding ability of the channel of the first speaker 311 cannot keep up, and during the movement, the cold air cannot be effectively introduced into the channel of the first speaker 311, and the connection between the cold air and the energy source 600 is easily disconnected. Another situation is that the guiding ability of the channel of the second speaker 312 is lower than that of the channel of the first speaker 311, and the cold air is easily retained at the small mouth end 310b, and the cold air cannot smoothly pass through the diversion module 300, and the guiding effect will be large but discounted; during the movement, it is also easy to disconnect the cold air and the energy source 600.

[0055] As an implementation mode, the flow guide module 300 takes the channel extension direction as the central axis and presents an axisymmetric structure; the inner walls of the first speaker 311 and the second speaker 312 have a section line along the central axis of the flow guide module 300 that is an arc, and the arc is concave toward the central axis of the flow guide module 300. The inner walls of the first speaker 311 and the second speaker 312 adopt a concave arc surface. After the cold air enters the large mouth end 310a1 of the first speaker 311 from the human body, it gradually gathers under the guidance of the arc surface, and there is no 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 310b1 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, so that the entire cold air guiding process tends to be smooth, and the cold air can establish a more stable connection with the energy source. Of course, the flow guide module 300 in the present application can also adopt a solution in which the section line along the central axis is a non-arc line, such as the following Fig.12 The double-horn-shaped guide member formed by two symmetrical truncated cone single horns is a truncated cone double-horn-shaped guide member. The inner walls of the two truncated cone double-horn-shaped guide members can be truncated cones, that is, the section lines of the inner walls of the first horn and the second horn along the central axis of the guide member are straight lines. Although the guide member has a poorer effect on the cold air than the guide module with an arc-shaped and concave section line, it is still better than the single-horn-shaped guide module.

[0056] The inner walls of the first horn 311 and the second horn 312 of the guide module 300 have a cross-sectional line on the central axis that is an arc line. From the large-mouth end to the small-mouth end of the first horn 311 and the second horn 312, the curvature of the arc line of the first horn 311 and the second horn 312 gradually increases or first increases and then decreases.

[0057] As an embodiment, the section 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 arc lines, and the curvature of the arc lines 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.

[0058] Specifically, the section line of the inner wall of the first horn 311 and the second horn 312 along the central axis of the guide module 300 is an arc s, and the arc s is concave toward the central axis, and the curvature of the arc increases from the large-mouth end 310a1 / 310a2 of the first horn 311 and the second horn 312 toward the corresponding small-mouth end 310b1 / 310b2; the arc extends toward the large-mouth end, and the curvature tends to zero; the tangent of the arc corresponding to the endpoint of the large-mouth end 310a1 of the first horn 311 tends to be perpendicular to the central axis; the arc approaches the central axis toward the small-mouth end 310b1 of the first horn 311, but does not intersect, that is, the diameter of the narrowest part in the middle of the guide module 300 tends to be infinitesimal.

[0059] 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 310a1 of the first speaker 311, it will be accelerated and introduced into the first speaker 311; it will pass through the small mouth end 310b1 of the first speaker 311 at an accelerated speed to avoid the cold air being blocked at the small mouth end 310b1 of the first speaker 311; conversely, after the cold air enters the second speaker 312, as the curvature from the small mouth end 310b2 to the large mouth end 310a2 of the second speaker 312 gradually increases, the cold air will be further accelerated after passing through the small mouth end 310b1 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, under the guidance of the inner wall of the second speaker 312, the acceleration gradually slows down from the small end 310b2 of the second speaker 312 to the large end 310a2, thereby avoiding the interruption of the connection between the cold air and the energy source 600 and enhancing the stability of the connection between the cold air and the energy source 600. Therefore, by using the guide module 300, the cold air guiding ability of the guide module 300 can be further enhanced on the basis of stabilizing the stability of the connection between the energy source 600 and the cold air, and the cold air guiding effect is better than the guide module 300 with a fixed arc curvature.

[0060] 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, promised for sale, or imported. The energy source 600 may be sold separately, and the energy source 600 may be added when it is used, and the energy source 600 may be installed 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, and 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.

[0061] The present cold-repelling device is further described below using various diversion modules as specific embodiments.

[0062] Embodiment 1: Curved double-horn body flow guide

[0063] Figure 2 is a flow diversion module provided in the first embodiment of the present application, such as Figure 2 As shown, the guide module 300 is a curved double-horn body guide piece 310, and the channel of the curved double-horn body guide piece 310 is double-horn shaped. The double-horn body guide piece 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, and 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, and 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 with the small mouth end 310b of the second horn 312 to form the double-horn shaped channel.

[0064] As an implementation method, Figure 3 As shown, the arc S of the inner wall of the channel of the cross-section of the double-horn body flow guide 315 with a gradual curvature along the central axis, the tangent of the endpoint of the arc corresponding to the large mouth end of the first horn is perpendicular or tends to be perpendicular to the central axis, and the tangent of the endpoint of the arc corresponding to 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.

[0065] The tangent line of the arc S at the end point of the small mouth end 310b is also parallel to the central axis, or in other words, the angle α2 with the central axis is infinitely close to 0. The profile 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.

[0066] If the opening angle of the large mouth end 310a of the double-horn body flow guide 315 with a gradual curvature is too narrow, that is, the section line of the double-horn body flow guide 315 with a gradual curvature 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 inside 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 backwards, the cold air will leak out, and the ability to gather the cold air will also decrease. Therefore, the curvature of the large mouth end 310a of the section line of the double-horn body flow guide 315 with a gradual curvature is made to tend 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 in the direction of the small mouth end 310b of the first speaker 311, but does not intersect. Similarly, the arc of the cross section of the second speaker 312 approaches the central axis in the direction of the small mouth end 310b of the second speaker 312, but does not intersect. That is, the diameters of the small mouth ends 310b of the first speaker 311 and the second speaker 312 tend to be infinitely small. Under the premise that the extension direction of the two large mouth ends 310a of the curvature gradient double speaker body flow guide 315 tends to be infinitely large, if the diameters of the small mouth ends 310b of the first speaker 311 and the second speaker 312 (i.e., the narrowest part of the channel of the curvature gradient double speaker body flow guide 315) can be infinitely small, the flow path of the cold air in the flow guide will be smoother, and the cold air can be guided more smoothly and more concentratedly, and the cold air extraction effect is better.

[0067] In addition, by using the double-horn flow guide 315 with gradual curvature, the energy source 600 does not need to face the large end 310a of the first horn 311. Even if it deviates from the coverage range of the large end 310a of the first horn 311 (i.e., the area projected along the central axis of the large end 310a of the first horn 311) by a certain distance, the cold air can still establish contact with the energy source 600. Therefore, the double-horn flow guide 315 with gradual curvature can better stabilize the connection between the energy source 600 and the cold air, and ensure the therapeutic effect.

[0068] It is understandable that the tangent lines of the large mouth ends 310a of the first horn 311 and the second horn 312 tend to be perpendicular to the central axis; the diameters of the small mouth ends 310b of the first horn 311 and the second horn 312 tend to be infinitely small, which is the direction that the curvature gradient double horn body flow guide 315 has always pursued, and the product can be continuously improved with the development of existing technologies. Therefore, as long as the curvature change trend of the arcs of the first horn 311 and the second horn 312 meets the law of increasing from the large mouth ends 310a of the first horn 311 and the second horn 312 to the corresponding small mouth ends 310b, it should fall within the protection scope of this application.

[0069] refer to Figure 4The diameter of the large ends 310a at both ends of the double-horn body guide piece 315 with a 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 conception of the present invention. In practical applications, the double-horn body guide piece 315 with a gradual curvature has clear dimensions. Here, three size ranges of the double-horn body guide piece 315 with a gradual curvature are given: large, medium, and small.

[0070] The large-sized curvature gradient double-horn body flow guide 315, the diameter R1 of the large mouth end 310a of the first horn 311 and the large mouth end 310a of the second horn 312 is 200mm-400mm, the corresponding diameter R2 of the small mouth end 310b is 20mm-40mm, and 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.

[0071] The medium-sized curvature gradient double-horn body guide member 315, the diameter R1 of the large mouth end 310a of the first horn 311 and the large mouth end 310a of the second horn 312 is 100mm-200mm, the corresponding diameter R2 of the small mouth end 310b is 10mm-20mm, and 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.

[0072] The small-sized curvature gradient double-horn body flow guide 315, the diameter R1 of the large mouth end 310a of the first horn 311 and the large mouth end 310a of the second horn 312 is 10mm-100mm, the corresponding diameter R2 of the small mouth end 310b is 1mm-10mm, and 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.

[0073] It has been verified that, with the existing technological level, the large-sized double-horn-body flow guide piece 315 with a gradual curvature has a stronger ability to gather cold air; while the small-sized double-horn-body flow guide piece 315 with a gradual curvature has a stronger ability to guide cold air. Different sizes of double-horn-body flow guide pieces 315 with a gradual curvature can be selected according to different application scenarios.

[0074] like Figure 5 As shown, 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 a gradual curvature along the central axis X, and the tangent lines corresponding to the endpoints of the large mouth ends 310a1 / 310a2 of the first horn 311 and the second horn 312 tend to be perpendicular to the central axis X.

[0075] Furthermore, the arc S approaches the parallel central axis X in the direction of the small mouth ends 310b of the corresponding first horn 311 and the second horn 312; the curvature approaches zero; the diameter of the small mouth ends 310b1 / 310b2 approaches the preset diameter R, which is not equal to zero, and the recommended range of R is 1-40mm.

[0076] In the above-mentioned embodiment, the extension direction of the large openings 310a at both ends of the double-flared flow guide 315 with a gradual curvature tends to be infinite, and the diameter of the narrowest part in the middle (and Figure 5 The direction pursued by the present invention is that the wall thickness of the double horn flow guide 315 with gradual curvature is as thin as possible, and the difference in wall thickness at each position of the double horn flow guide 315 with gradual curvature is as small as possible. This is another direction pursued by the present application. In terms of the existing technological level, it is relatively easy to enlarge the large end 310a. After the large end 310a is enlarged, the volume and weight of the product will increase accordingly. Under the premise that the wall thickness is as thin as possible, the diameter of the narrowest part in the middle of the double horn flow guide 315 with gradual curvature must be large enough to ensure the stability of the structure, otherwise the double horn flow guide 315 with gradual curvature will break in the middle under the action of the product gravity. Therefore, when the small end 310b has a preset diameter, the arcs of the first horn 311 and the second horn 312 tend to be parallel to the central axis in the direction of the small end 310b, so that the narrowest part in the middle of the double horn with gradual curvature maintains a trend of infinitely approaching the preset diameter, and the distance from the central axis is also getting smaller and smaller. In this way, when the cold air passes through the narrowest part in the middle of the double-horn body guide member 315 with gradually changing curvature, it will also tend to gather towards the central axis position, thereby improving the ability to guide the cold air.

[0077] The curvature variation trend of the double-horn air guide member with gradually changing 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.

[0078] As another embodiment, Figure 6 As shown, the section line of the inner wall of the first horn 311 and the second horn 312 along the central axis of the double-horn body guide member 315 with a gradual curvature is an arc line s. From the large-mouth end to the small-mouth end of the first horn 311 and the second horn 312, the curvature of the arc line of the first horn 311 and the second horn 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.

[0079] The end of the arc S corresponding to the large mouth end 310a of the first horn 311 and the second horn 312 of the double-horn flow guide 315 with a gradual curvature tends to be perpendicular to the central axis X. Of course, the arc S may not be perpendicular to the central axis, and may have a certain angle (such as an acute angle of 60° between the inward direction of the flow guide and the central axis), but the effect may not be as good as when it tends to be perpendicular.

[0080] The arc includes a first arc segment S1, a second arc segment S2 and a third arc segment S3; the first arc segment S1 has a head end corresponding to the large mouth end 310a of the curvature gradient double horn flow guide 315, the tail end of the second arc segment S2 corresponds to the small mouth end 310b of the curvature gradient double horn flow guide 315, and the tail end of the first arc segment S1 and the head end of the second arc segment S2 are respectively connected to the two ends of the third arc segment S3. 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, and the tail end is close to the central axis of the curvature gradient double horn flow guide 315, that is, the diameter R of the narrowest part of the arc S of the curvature gradient double horn flow guide 315 tends to 0. The curvature of the third arc segment S3 is greater than the curvature of the first arc segment S1 at the tail end and the curvature of the head end of the second arc segment S2.

[0081] Alternatively, it can also be understood as: the arc is divided into two parts, a first arc segment S1 and a 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, 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.

[0082] The arc S of the curvature gradient double-horn body flow guide 315 in the aforementioned embodiment first increases and then decreases from the large mouth end 310a to the small mouth end 310b. According to the existing material and process level, the middle part of the processed curvature gradient double-horn body flow guide 315 will be very thin, with low structural strength and easy to break. For this reason, the curvature of the first arc segment S1 increases from its head end to the tail end, which can ensure 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 reversely guided by the second horn 312, so that the cold air can smoothly establish contact with the energy source 600, and the cold air guiding efficiency and the stability of the cold air extraction process are guaranteed. 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 area in the middle area of ​​the double-horn body guide member 315 with a gradual curvature can be 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 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.

[0083] like Figure 7 As shown, in another embodiment, the tangent of the arc S of the first horn 311 and the second horn 312 of the double-horn body guide member 315 with gradual curvature corresponding to the large-mouth end 310a1 / 310a2 is perpendicular to the central axis.

[0084] Furthermore, the tangent of the arc s corresponding to the small mouth end 310b1 / 310b2 is parallel to the central axis X; the diameter of the small mouth end 310b can be flexibly set as needed, such as 1mm-40mm. The small mouth ends 310b of the first horn 311 and the second horn 312 have a smooth transition; from the large mouth end to the small mouth end, 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 mouth end is smaller than the channel diameter at any other point of the curvature gradient double horn body guide 315.

[0085] The large mouth end of the above-mentioned double-horn flow guide 315 with gradual curvature tends to be perpendicular to the central axis, and the diameter tends to be infinite; the diameter of the narrowest part in the middle tends to 0. This flow guide can fit a curve that meets the requirements during the design stage, but it is limited by the existing processing level and processing cost. If you want to make the above-mentioned double-horn flow guide 315 with gradual curvature, the cost is very high and it cannot be promoted on a large scale. In order to reduce the processing cost, this alternative implementation method clearly defines the boundaries between the large mouth end and the small mouth end of the double-horn flow guide 315 with gradual curvature. From the effect of guiding cold air, the large mouth end can basically hold the cold air emitted from the human body, and the cold air leaks less; while the small mouth end is parallel to the central axis, which can allow the cold air to be guided in a nearly horizontal direction, which can avoid the cold air from accumulating at the small mouth end and reduce the dispersion of the cold air. The cold air can be guided to the energy source 600 in a relatively concentrated manner, and the guiding effect of the cold air is better, which is a more ideal alternative. Through verification, it is found that the cold air guiding effect of the double-horn-body air guide 315 with gradually changing curvature is still better than that of the curved double-horn-body air guide 310 with a fixed arc curvature, and the cold air guiding effect is still relatively ideal.

[0086] In the embodiment of the present application, the small mouth end 310b1 of the first speaker 311 is directly connected to the small mouth end 310b2 of the second speaker 312, and the connection is smooth and has no abrupt transition and does not form a sharp corner. Figure 8 As shown, the curved double-horn flow guide 310 or even the curvature gradient double-horn flow guide 315 also includes a throat 310c; the throat 310c is hollow inside, open at both ends, and is cylindrical; the two ends of the throat 310c are respectively connected to the small mouth end 310b of the first horn 311 and the small mouth end 310b of the second horn 312; the small mouth end 310b of the first horn 311 and the second horn 312 are smoothly transitioned to the throat 310c.

[0087] The throat 310c may be cylindrical, and the cross section is a straight line parallel to the central axis X, so that the cold air can transition from the first speaker 311 to the second speaker 312 along the direction parallel to the central axis, and the cold air guiding effect is better. The cylindrical throat 310c is convenient for the clamp to fix the curved double speaker body flow guide 310 from the middle. Since the interior of the first speaker 311 and the second speaker 312 is a concave arc surface, the length of the throat 310c is as short as possible, so that the cold air guiding process from the first speaker 311, the throat 310c to the second speaker 312 will be smoother, which is conducive to improving the cold air guiding effect.

[0088] Of course, the throat 310c may also adopt an inwardly concave arc surface, the curvature variation rule of which 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.

[0089] like Fig. 9 As shown, multiple guiding warps 313 or guiding wefts 314 are also provided on the inner wall of the curved double-horn flow guide 310 or even the curvature gradient double-horn flow guide 315. Multiple guiding warps 313 are provided on the inner wall of the curvature gradient double-horn flow guide 315, and the multiple guiding warps 313 extend from the large mouth end 310a1 of the first horn 311 to the large mouth end 310a2 of the second horn 312; on the same vertical plane of the central axis of the curvature gradient double-horn flow guide 315, the spacing between two adjacent guiding warps 313 is equal. In this solution, the guiding warps 313 are used to further improve the guiding effect of the energy source 600 on the cold air in the human body, so that after the cold air is drawn out of the human body, it is indicated and guided by the guiding warps 313, and can pass through the flow guide better and faster, thereby improving the discharge efficiency of the cold air.

[0090] In which, along the extension direction from the center to the two ends of the double-horn body flow guide member 315 with gradually changing curvature, the distance between adjacent guide meridians 313 gradually increases.

[0091] In another embodiment, the inner wall of the curvature gradient double trumpet flow guide 315 is also provided with a plurality of guide latitudes 314, which surround the central axis of the channel and are arranged at intervals along the central axis of the channel. In this embodiment, concentric guide latitudes 314 are added to the inner wall of the curvature gradient double trumpet flow guide 315, and the diameter decreases from the large mouth end 310a of the trumpet to the small mouth end 310b. Through this step-by-step contraction closed-loop structure, the attraction of the cold air from the large mouth end 310a to the small mouth end 310b can be enhanced, making the trend of cold air discharge more obvious, and further ensuring the stability of the connection between the cold air and the energy source 600.

[0092] Among them, along the extension direction from the center to the two ends of the curvature gradient double horn body flow guide 315, the distance between the adjacent guide latitudes 314 gradually increases. In this scheme, the smaller the distance between the adjacent guide latitudes 314, the stronger the ability to attract cold air; conversely, the weaker it is. In order to make the cold air guiding process smoothly transition, the attraction of the flow guide to the cold air should increase from the two ends to the center, so that after the cold air comes out of the human body, it enters the flow guide in a gradually accelerated manner, and then is gradually decelerated. The process of guiding the cold air is more stable.

[0093] It is understandable that the above-mentioned guiding weft lines 314 and guiding warp lines 313 can be used alone or in combination, and can be used alone or in combination on the curved double-horn body flow guide 310. The guiding warp lines 313 and guiding weft lines 314 are formed by forming grooves on the inner wall.

[0094] In a combined embodiment, the inner wall of the curvature gradient double horn flow guide 315 is provided with a plurality of guiding warps 313 and a plurality of guiding wefts 314, and the plurality of guiding warps 313 are extended from the large mouth end 310a of the first horn 311 to the large mouth end 310a of the second horn 312; on the same vertical plane of the central axis of the curvature gradient double horn flow guide 315, the spacing between two adjacent guiding warps 313 is equal. The guiding wefts 314 surround the central axis of the curvature gradient double horn flow guide 315 and are arranged at intervals along the central axis direction of the curvature gradient double horn flow guide 315; the guiding wefts 314 and the guiding warps 313 are arranged in an alternating manner.

[0095] like Fig.10 As shown, the outer wall of the curvature gradient double-horn flow guide 315 is concave in the direction close to the central axis, and the wall thickness of the curvature gradient double-horn flow guide 315 increases from both ends to the center. In this scheme, the shape of the outer wall of the curvature gradient double-horn flow guide 315 is roughly the same as the shape of the inner wall. The two ends of the flow guide are large and the middle is thin, which is not very stable in structure. The closer to the edge part, the easier it is to deform. If the wall thickness is increased as a whole, the production cost of the flow guide will increase; if the edge is made thicker and the middle is made thinner, it will become heavy at both ends and light in the middle, which is easy to cause the curvature gradient double-horn flow guide 315 to break in the middle. Therefore, by gradually thickening the wall thickness of the curvature gradient double-horn flow guide 315 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 curvature gradient double-horn flow guide 315 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 and the flow guide effect is better.

[0096] like Fig.11 As shown, the curvature gradient double horn body flow guide 315 can also be formed by a shell with uniform thickness. Specifically, the outer wall of the curvature gradient double horn body flow guide 315 is concave in the direction close to the central axis, and the wall thickness of the curvature gradient double horn body flow guide 315 is the same at any position. The wall thickness of the curvature gradient double horn body flow guide 315 is uniform, and the inside and outside are consistent, which can enhance the ability to guide cold air.

[0097] It is understandable that, under the premise that the curvature gradient double-flared flow guide 315 meets the strength requirements, the smaller the wall thickness difference is, the better; the thinner the overall thickness is, the better.

[0098] Regarding the material of the curved double-horn body flow guide 310, the inventor found that non-transparent materials have a stronger attraction to cold air. When a flow guide made of non-transparent materials is used, cold air will be significantly retained when passing through the curved double-horn body flow guide 310, affecting the smooth passage of subsequent cold air. Over time, the flow guide capacity will decrease. However, using transparent materials will reduce the retention of cold air and can be used for a long time.

[0099] In view of the above concept, the material of the curved double-horn body flow guide 310 in this embodiment can be formed of a transparent material. Among them, the transparent material can be a transparent plastic, and a small amount of production can be produced by 3D printing. However, for the 3D printing method, the structural stability is poor, and there will be obvious deformation after long-term use. The larger the size of the curved double-horn body flow guide 310, the more severe the deformation, the higher the cost, and mass production is not cost-effective. Therefore, the curved double-horn body flow guide 310 in this solution can be produced by a mold, and a fixed mold is used for mass production. The mold is stable, the finished product effect is good, and the cost is lower.

[0100] In addition, the cross section of the flow guide module of the present application along the central axis is not limited to a concave arc surface. Fig.12 As shown, the cross section of the air guide module along the central axis may also be a straight line, and the first horn 311 and the second horn 312 are respectively in the shape of a truncated cone. The air guide module of this structure is also feasible.

[0101] Example 2: Nested flow guide components

[0102] As the flow guide module 300 provided in the second embodiment of the present application, the flow guide module 300 is a nested flow guide component 330, the two ends of the nested flow guide component 330 are open and the interior is hollow to form a channel, the nested flow guide component 330 includes at least two levels of curvature gradient double horn flow guide pieces 315, the sizes of the curvature gradient double horn flow guide pieces 315 of different levels are different, and the curvature gradient double horn flow guide piece 315 of the next level is nested in the curvature gradient double horn flow guide piece 315 of the previous level, and the channel of the nested flow guide component 330 is the channel in the curvature gradient double horn flow guide piece 315 of the smallest size. In the nested flow guide component 330, when viewed along the central axis direction of the curvature gradient double horn flow guide piece 315 of the previous level, the through holes of the curvature gradient double horn flow guide piece 315 of the previous level and the curvature gradient double horn flow guide piece 315 of the next level at the narrowest part of the channel at least partially overlap.

[0103] like Fig.13 As shown, 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 pieces 315, and the number of curvature gradient double horn body guide pieces 315 in each stage is only one.

[0104] Specifically, the nested guide assembly 330 in the embodiment of the present application is formed by nesting a first curvature gradient double horn guide piece 321 and a second curvature gradient double horn guide piece 322, the size of the first curvature gradient double horn guide piece 331 is smaller than the size of the second curvature gradient double horn guide piece 332, and the first curvature gradient double horn guide piece 331 is nested in the second curvature gradient double horn guide piece 332; and, along the central axis direction of the second curvature gradient double horn guide piece 332, the channel of the first curvature gradient double horn guide piece 331 and the channel of the second curvature gradient double horn guide piece 322 are at the narrowest through hole (reference Figure 5 , 6 The position of R in the figure completely overlaps.

[0105] 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 member 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 member 322, and does not mean that the two positions have the same size and overlap the edges.

[0106] For the shapes of the first double-horn flow guide member 331 with gradual curvature and the second double-horn flow guide member 332 with gradual curvature, specific reference is made to the description of the double-horn flow guide member 315 with gradual curvature in the first embodiment.

[0107] It should be understood that in the embodiment of the present application, the meaning of "nesting" is: first, the curvature gradient double horn flow guide pieces between different levels must meet the nesting conditions, and second, the curvature gradient double horn flow guide piece of the previous level must completely cover the curvature gradient double horn flow guide piece of the small size. For easy understanding, the present application provides a specific example. From the front of the nested flow guide component 330 (along the central axis direction of the nested flow guide component 330), the outer contour of the large mouth end of the second curvature gradient double horn flow guide piece 332 surrounds the outer contour of the large mouth end of the first curvature gradient double horn flow guide piece 331, and the large mouth end of the first curvature gradient double horn flow guide piece 331 will not exceed the range covered by the large mouth end of the second curvature gradient double horn flow guide piece 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 horn guide member 332 will completely block the first curvature gradient double horn guide member 331 , so that only the outline shape of the second curvature gradient double horn guide member 332 can be seen in this direction.

[0108] 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 after 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, the attraction of the cold air can be enhanced through secondary guidance, 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 component 330, the attraction formed by the double guidance brought by the second curvature gradient double horn guide piece 332 and the first curvature gradient double horn guide piece 331 is sufficient to allow more concentrated cold air to pass through the throat 310c of the first curvature gradient double horn guide piece 331, and then drive the deeper cold air of the human body out into the nested guide component 330, which can better clear the root cause of the cold air and make the cold air eliminated more thoroughly, so as to improve the health level of the human body.

[0109] Moreover, the nested flow guide component 330 in the embodiment of the present application adopts a two-stage nested curvature gradient double horn flow guide 315, which is easy to manufacture and has low cost. The volume of the entire nested flow guide component 330 is relatively small, which is suitable for removing cold air from a certain local part of the human body.

[0110] In this embodiment, the center points of the first curvature gradient double horn flow guide 331 and the second curvature gradient double horn flow guide 332 coincide. After adopting this design, the first curvature gradient double horn flow guide 331 and the second curvature gradient double horn flow guide 332 converge toward the same center position for the cold air, so that the cold air is more concentrated, thereby being able to draw out the cold air at a deeper level. In addition, only one first curvature gradient double horn flow guide 331 is nested inside the second curvature gradient double horn flow guide 332, and the large mouth end 310a of the first curvature gradient double horn flow guide 331 is close to the throat 310c position of the second curvature gradient double horn flow guide 332, and the arc surface transition between the first curvature gradient double horn flow guide 331 and the second curvature gradient double horn flow guide 332 is more natural, so that the process of drawing out the cold air is not easily disturbed.

[0111] like Fig.14As shown, in this embodiment, the central axis of the first curvature gradient double horn flow guide 331 coincides with the central axis of the second curvature gradient double horn flow guide 332. After adopting this design, the second curvature gradient double horn flow guide 332 and the first curvature gradient double horn flow guide 331 converge in the same straight line for cold air, so that the cold air is guided out along the same straight line, which makes the cold air guiding stable and less likely to be disturbed by the external environment.

[0112] In the embodiment, the first curvature gradient double horn flow guide 331 is a scaled version of the second curvature gradient double horn flow guide 332. Since the two-stage curvature gradient double horn flow guide 315 have the same shape and good consistency, and the inner wall curved surface of the two-stage curvature gradient double horn flow guide 315 has a natural transition, the cold air guiding process is smoother.

[0113] like Fig.15 and Fig.16 As shown, there is an air duct 339 between the first curvature gradient double horn body guide piece 331 and the second curvature gradient double horn body guide piece 332, and 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 horn body guide piece 331 and the inner side of the second curvature gradient double horn body guide piece 332.

[0114] Since there is an airway 339 between the two levels of the 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, 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 on the cold air.

[0115] For the airway 339, since the curvature gradient double trumpet body flow guide 315 is a double trumpet-shaped structure with wide ends and narrow middle, when the first curvature gradient double trumpet body flow guide 331 is placed in the channel of the second curvature gradient double trumpet body flow guide 332, since the center points of the first curvature gradient double trumpet body flow guide 331 and the second curvature gradient double trumpet body flow guide 332 coincide with each other, the two large mouth ends 310a of the first curvature gradient double trumpet body flow guide 331 are respectively located at the second curvature gradient double trumpet body flow guide 332. On both sides of the center point, the first curvature gradient double horn body flow guide 331 needs to be moved to pass through the minimum through hole of the channel of the second curvature gradient double horn body flow guide 332. Therefore, the size of the large mouth end 310a of the first curvature gradient double horn body flow guide 331 will be smaller than the minimum through hole diameter of the channel of the second curvature gradient double horn 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 horn body flow guide 331 and the second curvature gradient double horn body flow guide 332.

[0116] Moreover, there is no direct contact between the first curvature gradient double horn flow guide piece 331 and the second curvature gradient double horn flow guide piece 332, and the edges of the large mouth ends 310a at both ends of the first curvature gradient double horn flow guide piece 331 are glued and fixed to the inner wall of the second curvature gradient double horn flow guide piece 332 by dispensing glue, so that the center lines of the first curvature gradient double horn flow guide piece 331 and the second curvature gradient double horn flow guide piece 332 coincide.

[0117] Optionally, the edges of the large mouth ends 310a at both ends of the first curvature gradient double horn body flow guide 331 are fixed to the inner wall of the second curvature gradient double horn 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 horn body flow guide 331 and the second curvature gradient double horn body flow guide 332, the area of ​​the airway 339 is prevented from being reduced, which would affect the ability of the second curvature gradient double horn body flow guide 332 to guide cold air.

[0118] It should be noted that, in the embodiment of the present application, when viewed along the central axis direction of the second curvature gradient double-horn body guide piece 332, it is feasible that the through hole at the narrowest part of the channel of the first curvature gradient double-horn body guide piece 331 only partially overlaps with the through hole at the narrowest part of the channel of the second curvature gradient double-horn body guide piece 332. Similarly, 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 can be utilized to allow more concentrated cold air to pass through the throat 310c of the first curvature gradient double-horn body guide piece 331, thereby driving the deeper cold air of the human body out and into the nested guide assembly 330. However, due to the offset between the throat 310c of the first curvature gradient double-horn body guide piece 331 and the throat 310c of the second curvature gradient double-horn body guide piece 332, the stability of the cold air after passing through the nested guide assembly 330 will be slightly poor.

[0119] At this time, the center points of the first curvature gradient double horn flow guide member 331 and the second curvature gradient double horn flow guide member 332 do not overlap, and the center lines do not overlap either. Even the first curvature gradient double horn flow guide member 331 may not be a proportional scaled version of the second curvature gradient double horn flow guide member 332. As long as the first curvature gradient double horn flow guide member 331 can be nested inside the channel of the second curvature gradient double horn flow guide member 332, it should fall within the protection scope of the present application.

[0120] like Fig.17 As shown, as the second implementation in the embodiment of the present application, the difference from the first implementation is that the present implementation 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 horn guide 333, a fourth curvature gradient double horn guide 334 and a fifth curvature gradient double horn guide 335, the third curvature gradient double horn guide 333 is nested in the fourth curvature gradient double horn guide 334, the fourth curvature gradient double horn guide 334 is nested in the fifth curvature gradient double horn guide 335, and, viewed along the central axis direction of the fifth curvature gradient double horn guide 335, the third curvature gradient double horn guide 333, the fourth curvature gradient double horn guide 334 and the fifth curvature gradient double horn guide 335 overlap in the through holes at the narrowest part of the channel.

[0121] like Fig.18As shown, as the third implementation in the embodiment of the present application, the difference from the above implementation is that in the implementation of the present application, the number of the next-level curvature gradient double-horn body guide pieces 315 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 in parallel 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.

[0122] As a way to form airway 339, such as Fig.19 As shown, the area of ​​the large mouth end of the second-stage curvature gradient double horn flow guide 337 is smaller than the area of ​​the narrowest part (throat neck) of the first-stage curvature gradient double horn flow guide 336, that is, the size of the through hole at the smallest part of the channel; the fitting part of the two second-stage curvature gradient double horn flow guides 337 is fixed to the inside of the first-stage curvature gradient double horn flow guide 336 by glue spotting. There are three specific glue spotting positions 3391, and the angle between adjacent glue spotting positions 3391 is 120°, so that while ensuring stability, the area of ​​the airway 339 between the adjacent two-stage curvature gradient double horn flow guides 315 is also reduced. Of course, according to actual conditions, the glue spotting positions can be increased or decreased, or even the fixing method can be changed, such as by clamping, welding, etc.

[0123] As another way to form the airway 339, Fig. 20 and Fig.21 As shown, a plurality of guiding warps 313 and a plurality of guiding wefts 314 are arranged on the inner wall of the first-stage curvature gradient double-horn body guide 336, and the plurality of guiding warps 313 are arranged to extend from one end opening of the channel to the other end opening of the channel, and the plurality of guiding wefts 314 surround the central axis of the channel and are arranged at intervals along the central axis direction of the channel, and the guiding warps 313 and the guiding wefts 314 are both groove structures to form an airway 339. By adding the guiding warps 313 and the guiding wefts 314, the guidance of the cold air can be made more directional, so that the guiding effect is better.

[0124] like Fig. 22As shown, the fourth embodiment provided as an example of the present application is different from the third embodiment in that the nested guide assembly 330 in the present embodiment adopts a three-level nesting method, that is, a three-level double nested guide assembly. Specifically, the nested guide assembly 330 includes a first-level curvature gradient double horn guide 336, a second-level curvature gradient double horn guide 337, and a third-level curvature gradient double horn guide 338. The number of the first-level curvature gradient double horn guide 336 is one, the number of the second-level curvature gradient double horn guide 337 is two, and the number of the third-level curvature gradient double horn guide 338 is four; two of the third-level curvature gradient double horn guides 338 are nested in parallel in one of the second-level curvature gradient double horn guides 337, and two of the second-level curvature gradient double horn guides 337 are nested in parallel in the first-level curvature gradient double horn guide 336.

[0125] Moreover, the edges of the large mouth ends of 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 fit together without a gap, and the edges of the large mouth ends of 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 fit together without a gap.

[0126] Example 3: Mobile Components

[0127] The mobile component of the present application can move on a certain plane or track, which can be achieved by 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.

[0128] In the embodiment of the present application, after waiting for a first preset time, the control module 400 drives the moving assembly 100 to drive the energy source fixing structure 200 and the diversion module 300 to move a first preset distance away from the user to be relieved of cold. The first preset time can be set to 10-300s, and the first preset distance can be set to 50-200cm.

[0129] In the embodiment of the present application, after the control module 400 drives the mobile component 100 to drive the energy source fixed structure 200 and the diversion module 300 to move a first preset distance away from the user to be relieved of cold, it also controls the mobile component 100 to stay for a second preset time. The second preset time can be set to 10-300s. In order to further save user waiting time, the first preset time and / or the second preset time can be further reduced to 10-60s.

[0130] 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.

[0131] The specific structure of the mobile component can be implemented in the following ways.

[0132] like Fig.23 As shown, the mobile assembly is a trolley structure, including a frame 111, a mounting platform 117, a motor 113 and wheels 112. There are four wheels, which are arranged at the bottom of the frame, the mounting platform is arranged at the top of the frame, and the energy source fixing structure 200 and the diversion module 300 are fixed on the mounting platform. The motor drives the wheels to rotate, and the control module 400 is arranged on the frame 11, which is used to control the running direction, running speed and running time of the motor. Before use, the energy source is placed on the energy source fixing structure; when in use, the control module drives the wheels to rotate, drives the mobile assembly to move as a whole, and then drives the energy source fixing structure and the diversion module to move.

[0133] like Fig.24 As shown, the mobile component is also a trolley structure. It includes a tricycle frame 111, a mounting platform 117 and a support frame 142. The control module 400 is arranged in the frame 111 to drive the frame to move. The support frame 142 adopts a tripod 123. The three legs of the tripod are arranged on the frame 111, and the mounting platform 117 is fixed on the top. The energy source fixing structure 200 and the diversion module 300 are fixed on the mounting platform 117. Before use, the energy source 600 (such as moxa stick 610) is placed on the energy source fixing structure; when in use, the control module drives the tricycle frame to drive the mobile component to move as a whole, and then drives the energy source fixing structure and the diversion module to move.

[0134] like Fig.25 As shown, the moving assembly is a slide bar structure. It includes a slide bar assembly 141, a support frame 142 and a mounting platform 117. The slide bar assembly includes two parallel slide bars 1411 and two slide bar fixing blocks 1412; the two ends of the slide bar are respectively fixed between the two slide bar fixing blocks to form a track. The support frame 142 adopts a height-adjustable tripod 123, which has two parts, which are respectively fixed at the bottom of the two slide bar fixing blocks to fix the slide bar and adjust the height of the slide bar. The mounting platform is set on the slide bar, and the energy source fixing structure 200 and the diversion module 300 are fixed to the mounting platform 117. The control module 400 is fixed at one end of the slide bar to control the movement of the mounting platform on the slide bar. Before use, the energy source 600 (such as essential oil 620) is placed on the energy source fixing structure; when in use, the slide bar and the support frame remain stationary, and the control module drives the mounting platform to move on the slide bar, driving the energy source fixing structure and the diversion module to move.

[0135] like Fig.26 As shown, the present application also provides a method for using a cold-removing device, which is used for the above-mentioned cold-removing device, and the method comprises the steps of:

[0136] S1: Align one end of the diversion module with the user to be de-cold-free, 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-cold-free is a first alignment distance, and the distance between the diversion module and the energy source is a second alignment distance;

[0137] 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 de-cold.

[0138] In step S1, the two ends of the channel in the diversion module are respectively aligned with the user to be de-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.

[0139] In step S2, the first preset time is 10-300s (to avoid waiting too long, it can be further limited to 10-60s), and the first preset distance is 50-200cm. Moreover, 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 dispelled cold, 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.

[0140] After step S2, the energy source and the flow guiding module stay for a second preset time (eg, 10-300 seconds, which can be further limited to 10-60 seconds to avoid waiting too long).

[0141] 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 led out of the body. Therefore, the energy source can be removed, and the user can move to another place to continue physical therapy, and the cold air removal equipment can be vacated for other users to use, thereby improving the utilization efficiency of the equipment. Of course, it is also feasible to keep the energy source intact and remove the diversion module. At this time, the connection between the cold air and the energy source will not be interrupted.

[0142] When the energy source is an wormwood product, Fig. 27 As shown, the method for using the cold-removing device comprises the following steps:

[0143] 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;

[0144] SA2: Control the moving component to wait for a first preset time;

[0145] SA3: controlling the moving component to drive the moxa product and the diversion module to move simultaneously in a direction away from the user to be de-cold for a first preset distance;

[0146] SA4: controlling the moving component to make the energy source and the flow guiding module stay for a second preset time;

[0147] SA5: Remove the moxa product from the moving component.

[0148] 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 the guide member, 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 led out of the body. Therefore, the moxa product can be removed, allowing the user to move to another place to continue physical therapy, and the cold air removal equipment can be vacated for other users to use, thereby improving the utilization efficiency of the equipment. Of course, it is also feasible to keep the moxa product immovable and remove the guide component. At this time, the connection between the cold air and the moxa product will not be interrupted.

[0149] It should be noted that when the equipment is started, the moxa product remains in a lit state, that is, before step SA1, the moxa product is lit, and in step SA5, the lit moxa product is removed. After step SA5, the user to get rid of the cold has direct contact with the burning moxa product; when the moxa product is extinguished or burned out, the entire therapy process ends.

[0150] Of course, during the treatment process, moxa products can be used directly without being ignited, but the stage for establishing contact will be longer, that is, the first preset time will be greater than 30s.

[0151] When the energy source is essential oil, Fig.28 As shown, the method for using the cold-removing device comprises the following steps:

[0152] SB1: Make the distance between the essential oil bottle of the cold-removing device and the user to be cold-removed be a preset alignment distance;

[0153] SB2: Open the cap of the essential oil bottle;

[0154] SB3: Control the moving component to wait for a first preset time;

[0155] SB4: Control the moving component to drive the essential oil bottle and the diversion module to move a first preset distance in a direction away from the user to be de-cold;

[0156] SB5: controlling the moving component to make the energy source and the diversion module stay for a second preset time;

[0157] SB6: Close the bottle cap of the essential oil bottle.

[0158] Among them, SB1 and SB2 can be carried out simultaneously, or SB1 or SB2 can be carried out first; in addition, before starting the device, the user can apply volatile liquid on the human body to remove the cold. The volatile liquid is helpful to quickly draw out the cold and assist the cold to establish a connection with the essential oil faster.

[0159] In step SB3, the first preset time is 15-30s. It has been verified that within this range, the essential oil and cold air can establish a relatively stable connection. At the same time, the cold air is still in the state of being drawn out. At this time, start the essential oil and the diversion module to move along the trend of the cold air being drawn out. The connection is not easily interrupted, which can enhance the trend of drawing out the cold air.

[0160] In step SB4, the moving speed of the essential oil and the diversion module ranges from 2 to 5 mm / s, and the first preset distance is 60 cm to 100 cm. It has been verified that within this range, the cold air can be continuously drawn out during the movement of the essential oil, and the trend of drawing out can still be maintained after the movement of the essential oil ends.

[0161] In step SB5, the second preset time does not exceed 1 minute. After the essential oil stops moving, the cold air will continue to be drawn out for a period of time. During this period, the body can continue to stay, which can further enhance the effect of drawing out the cold air. After this time, the cold air and the essential oil tend to be balanced, and the effect of drawing out the cold air is not obvious, so it is not necessary to continue to stay. It has been verified that when the second stay time is controlled within 1 minute, the trend of drawing out the cold air is more obvious, and there is a significant attenuation after more than 1 minute, specifically between 10-20s.

[0162] Moreover, when using the cold-removing equipment, it can also be combined with a one-button start to reduce manual operations and improve work efficiency. It can also be combined with a voice prompter to give prompts when the essential oil and diversion module reach the initial position and end position, or to issue a reminder when resetting. It can also be combined with a counter to facilitate counting and statistics for the operator.

[0163] The above content is a further detailed description of the present application in combination with specific optional implementation methods, and it cannot be determined that the specific implementation of the present application is limited to these descriptions. For ordinary technicians in the technical field to which the present application belongs, several simple deductions or substitutions can be made without departing from the concept of the present application, which should be deemed to fall within the scope of protection of the present application.

[0164] The claimed effects of the technical solution of this application have been verified by experiments. Through experiments, it has been verified that the effect of removing cold air by adding a diversion module between the energy source and the human body through one movement is significantly improved compared with the method of simply moving the energy source without adding a diversion module. And the effect of using a diversion module with a double-horn diversion member with a gradual curvature is better than that of a diversion module with a single-horn structure.

[0165] Energy sources can be moxa sticks and essential oils, which are similar to moxa sticks in improving range of motion, but essential oils are better than moxa sticks in improving pain.

[0166] The effect of using the nested guide assembly is better than the effect of using the double-flared guide piece with gradually varying curvature.
