Description

Nested deflector assemblies, deflectors and cold air removal devices Technical Field

[0001] The present application relates to the field of health care equipment, and in particular to a nested diversion assembly, a diverter and a cold-dispelling device. Background Art

[0002] Many diseases we see in life, such as frozen shoulder, old cold legs, etc., often show symptoms such as joint pain and limited movement, which are all caused by the invasion of exogenous evil into the human body. In Chinese medicine records, evil spirits are divided into wind, cold, heat, dampness, dryness, and fire. Taking cold air as an example, in winter when the temperature is relatively low, or because the temperature drops sharply, the human body does not pay enough attention to cold protection and warmth preservation, then it is often easy to feel cold evil. In addition, getting caught in the rain and wading in water, or sweating in the wind, are also often important reasons for feeling cold evil. Prior application (PCT / CN2023 / 091852) discloses a device for dispelling cold air and its use method, which can be used to guide the cold air out of the body through a guide piece in combination with an energy source to achieve the effect of dispelling the cold air.

[0003] However, after further experiments, the inventors found that the product previously applied for could not drive the deeper cold air out of the human body through the guide member during movement.

[0004] Summary of the Invention

[0005] The purpose of this application is to provide a nested diversion component, a diverter and a cold-removing device that can bring out the coldness in the deeper levels of the human body, better clear the root causes of the coldness, and improve the health level of the human body.

[0006] The present application discloses a nested guide assembly, which includes at least two levels of curvature gradient double-horn body guide pieces, the sizes of the curvature gradient double-horn body guide pieces at different levels are different, and the curvature gradient double-horn body guide pieces at the lower level are nested in the curvature gradient double-horn body guide pieces at the upper level; in the nested guide assembly, viewed along the central axis direction of the curvature gradient double-horn body guide piece at the upper level, the through holes of the curvature gradient double-horn body guide piece at the upper level and the curvature gradient double-horn body guide piece at the lower level at the narrowest part of the channel at least partially overlap.

[0007] In this solution, a nested guide assembly is adopted in which multiple levels of curvature gradient double-horn body guide pieces are nested. Since the curvature gradient double-horn body guide piece of the upper level has a larger opening and a wide coverage area, it can gather more cold air; and the curvature gradient double-horn body guide piece of the lower level has a smaller opening, so that the cold air gathered through the opening of the curvature gradient double-horn body guide piece of the upper level enters the small wormhole, and through secondary guidance, it can enhance the attraction of the cold air, allowing the cold air to pass through the nested guide assembly more stably; at the same time, the center of the curvature gradient double-horn body guide piece of the lower level is narrower, which can make the cold air more concentrated. After adopting the nested guide assembly, the attraction formed by at least two layers of guidance brought by the upper-level curvature gradient double-horn guide piece and the lower-level curvature gradient double-horn guide piece is sufficient to allow more concentrated cold air to pass through the central through hole of the lower-level curvature gradient double-horn guide piece, thereby driving the deeper cold air of the human body out into the nested guide assembly, which can better clear the root cause of the cold air and improve the health level of the human body.

[0008] Optionally, in the nested guide assembly, the central axes of all the double-horn guide members with gradually varying curvatures are on the same straight line.

[0009] In this solution, after all the curvature gradient double-horn body guide pieces are coaxially arranged, the convergence direction of the cold air of the upper-level curvature gradient double-horn body guide piece and the lower-level curvature gradient double-horn body guide piece tends to be in the same straight line, so that the cold air is guided out along the same straight line, making the cold air guidance stable and not easily disturbed by the external environment.

[0010] Optionally, in the nested guide assembly, an air passage is provided between two adjacent levels of the double-horn guide members with gradually varying curvatures, and both ends of the air passage are respectively connected to the outside at both ends of the nested guide assembly.

[0011] In this solution, since there is an air passage between the two adjacent levels of the double-horn body guide pieces with gradual curvature, the double-horn body guide piece with gradual curvature of the next level does not block the middle through hole of the double-horn body guide piece with gradual curvature of the previous level, that is, the first horn and the second horn of the double-horn body guide piece with gradual curvature of the previous level are still connected, and the double-horn body guide piece with gradual curvature of the previous level still retains sufficient cold air guiding ability, which can attract cold air into its interior, and then guide the cold air into the double-horn body guide piece with gradual curvature of the next level, thereby enhancing the cold air guiding effect.

[0012] Optionally, there is only one double-horn-shaped flow guide member with gradually varying curvature at each level, and the center points of all the double-horn-shaped flow guide members with gradually varying curvature coincide with each other.

[0013] In this solution, each level of gradually changing curvature double-flared air guide converges the cold air toward the same central location, concentrating the cold air and drawing it out from deeper levels. Furthermore, only one lower-level gradually changing curvature double-flared air guide is nested between the upper-level gradually changing curvature double-flared air guide; the large end of the lower-level gradually changing curvature double-flared air guide is closer to the center of the upper-level gradually changing curvature double-flared air guide, creating a more natural arc transition between adjacent levels of gradually changing curvature double-flared air guides, thus minimizing interference with the cold air's drawing out process.

[0014] Optionally, the nested guide assembly includes a first double-horn body guide piece with a gradual curvature and a second double-horn body guide piece with a gradual curvature, and the first double-horn body guide piece with a gradual curvature is nested in the second double-horn body guide piece with a gradual curvature.

[0015] In this solution, the nested diversion assembly uses two layers of nested curvature gradient double horn diversion parts, which are easy to manufacture and low in cost. In addition, the entire nested diversion assembly is relatively small in size, making it suitable for removing cold air from a specific part of the human body.

[0016] Optionally, the nested guide assembly includes a third curvature gradient double horn body guide piece, a fourth curvature gradient double horn body guide piece and a fifth curvature gradient double horn body guide piece, the third curvature gradient double horn body guide piece is nested in the fourth curvature gradient double horn body guide piece, and the fourth curvature gradient double horn body guide piece is nested in the fifth curvature gradient double horn body guide piece.

[0017] In this solution, as the number of levels in the nested guide assembly increases, the more nesting levels there are, so that the size of the outermost layer's double-horn body guide member with a gradual curvature becomes larger, and the size of the innermost layer's double-horn body guide member with a gradual curvature becomes smaller, so that a larger opening area and a smaller central through hole can be obtained at the same time, so that the guiding effect of the nested guide assembly is better; however, as the number of nesting levels increases, the size of the nested guide assembly will increase significantly, affecting actual use; therefore, in order to avoid the size of the guide assembly being too large and to improve the guiding effect of the guide assembly, the nested guide assembly is designed as a three-layer nested structure consisting of a third double-horn body guide member with a gradual curvature, a fourth double-horn body guide member with a gradual curvature, and a fifth double-horn body guide member with a gradual curvature.

[0018] Optionally, the number of the curvature gradient double-horn body air guide members of the next level is at least two, and at least two of the curvature gradient double-horn body air guide members of the next level are nested side by side in the curvature gradient double-horn body air guide member of the previous level; wherein, there is no gap between at least two of the curvature gradient double-horn body air guide members of the next level nested in the same curvature gradient double-horn body air guide member of the previous level.

[0019] In this solution, since at least two of the curvature gradient double-horn body guide pieces of the next level are nested inside a curvature gradient double-horn body guide piece of the previous level, and there is no gap between the curvature gradient double-horn body guide pieces connected in series, the cold air will be more concentrated and more directed after passing through at least two of the curvature gradient double-horn body guide pieces of the next level connected in series; and since the curvature gradient double-horn body guide piece of the previous level is nested outside the curvature gradient double-horn body guide piece of the series, the cold air will not be retained between the curvature gradient double-horn body guide pieces of the next level connected in series under the guidance of the curvature gradient double-horn body guide piece of the previous level, and the cold air can pass through the nested guide assembly in a more concentrated manner, further improving the stability of the cold air discharge while ensuring that the cold air can smoothly pass through the curvature gradient double-horn body guide piece of the next level.

[0020] Optionally, the nested guide assembly includes a first-stage curvature gradient double-horn body guide piece and a second-stage curvature gradient double-horn body guide piece, the number of the first-stage curvature gradient double-horn body guide piece is one, and the number of the second-stage curvature gradient double-horn body guide piece is two; two of the second-stage curvature gradient double-horn body guide pieces are nested side by side in the first-stage curvature gradient double-horn body guide piece.

[0021] In this solution, since too many next-level double-flare body guide pieces with gradual curvature are nested inside the previous-level double-flare body guide piece with gradual curvature, the next-level double-flare body guide piece with gradual curvature will protrude too much from the center of the previous-level double-flare body guide piece with gradual curvature. That is, the large mouth end of the next-level double-flare body guide piece with gradual curvature located at the edge will be closer to the large mouth end of the previous-level double-flare body guide piece with gradual curvature, resulting in the cold air being gathered by the large mouth end of the previous-level double-flare body guide piece, and it is not easy to guide it into the interior of the next-level double-flare body guide piece with gradual curvature.

[0022] Optionally, the nested guide assembly includes a first-stage curvature gradient double horn body guide piece, a second-stage curvature gradient double horn body guide piece and a third-stage curvature gradient double horn body guide piece, the number of the first-stage curvature gradient double horn body guide piece is one, the number of the second-stage curvature gradient double horn body guide piece is two, and the number of the third-stage curvature gradient double horn body guide piece is four; two of the third-stage curvature gradient double horn body guide pieces are nested side by side in one of the second-stage curvature gradient double horn body guide pieces, and two of the second-stage curvature gradient double horn body guide pieces are nested side by side in the first-stage curvature gradient double horn body guide piece.

[0023] In this solution, the more nested layers there are inside the nested guide component, the better the guiding effect will be, but it will lead to a larger volume of the nested guide component and a higher cost. Considering all factors, it would be more appropriate to adopt a three-layer nested design of a first-level curvature gradient double-horn guide component, a second-level curvature gradient double-horn guide component and a third-level curvature gradient double-horn guide component.

[0024] Optionally, the double-horn flow guide member with gradually varying curvature at the next level is a scaled-down version of the double-horn flow guide member with gradually varying curvature at the previous level.

[0025] In this solution, the curvature gradient double-horn body guide pieces at each level have the same shape and good consistency, and the inner wall curved surfaces of the two adjacent levels of curvature gradient double-horn body guide pieces transition naturally, making the cold air guiding process smoother.

[0026] Optionally, the distance between the large mouth end of the double-flared flow guide member with gradual curvature at the next level and the corresponding large mouth end of the double-flared flow guide member with gradual curvature at the previous level exceeds one quarter of the length of the double-flared flow guide member with gradual curvature at the previous level.

[0027] In this solution, after the two adjacent levels of curvature gradient double-flare body guide pieces are nested, the end face of the large mouth end of the curvature gradient double-flare body guide piece of the next level exceeds half the length of the single-sided flare in the curvature gradient double-flare body guide piece of the previous level, thereby preventing the end of the curvature gradient double-flare body guide piece of the next level from protruding too much, resulting in the cold air gathered by the curvature gradient double-flare body guide piece of the previous level not being easily introduced into the internal channel of the curvature gradient double-flare body guide piece of the next level.

[0028] Optionally, the distance between the large mouth end of the double-flared flow guide member with gradual curvature at the next level and the corresponding large mouth end of the double-flared flow guide member with gradual curvature at the previous level exceeds one third of the length of the double-flared flow guide member with gradual curvature at the previous level.

[0029] In this solution, the end of the next-level double-horn body guide piece with a gradual curvature transitions more naturally with the inner wall of the previous-level double-horn body guide piece with a gradual curvature, and the cold air guiding process is smoother.

[0030] Optionally, the edge of the large mouth end of the double-horn-shaped flow guide member with gradually changing curvature at the next level is fixed to the inner wall of the double-horn-shaped flow guide member with gradually changing curvature at the previous level through a fixing structure.

[0031] In this solution, the double-horn-shaped flow guide member with gradually changing curvature at the next level is fixed nearby to minimize the space occupied by the fixed structure and reduce the obstruction of the cold air guiding path by the fixed structure.

[0032] The present application also discloses a deflector, which includes at least one nested deflector assembly as described above and at least one independent double-horn deflector with a gradual curvature, and the double-horn deflector with a gradual curvature and the nested deflector assembly are arranged in parallel in sequence; or, the deflector includes at least two nested deflector assemblies as described above, and the nested deflector assemblies are arranged in parallel in sequence.

[0033] In this solution, by placing two or more nested guide components in parallel, or placing nested guide components and curvature gradient double-horn guide pieces in parallel, the cold air can be converged twice or more, and the tendency of the cold air to move toward the energy source along the axis direction is stronger, making it less likely for the cold air to attenuate during the movement. Compared with a single nested guide component, the cold air after the series design in this solution is converged multiple times, and the final amount of cold air that is scattered is less, the connection between the cold air and the energy source is stronger, and the stability is better. During the movement process, the secondary convergence of the latter-stage nested guide component or curvature gradient double-horn guide piece has a stabilizing effect on the former-stage nested guide component or curvature gradient double-horn guide piece, and the former-stage nested guide component or curvature gradient double-horn guide piece is less affected by changes in the external environment and is more stable during the movement. In summary, the use of a deflector can enhance the guiding effect of the cold air, while stabilizing the connection between the cold air and the energy source during the movement, and improving the effect of removing the cold air.

[0034] Optionally, the deflector is composed of at least two nested deflector components, and the nested deflector components have the same size.

[0035] In this solution, since the nested guide components have the same size, each nested guide component has the same effect on guiding and converging the cold air. The cold air will not undergo sudden changes when passing through the guide, allowing the cold air to pass through the guide more smoothly.

[0036] Optionally, the deflector includes two nested deflector components and a double-flared deflector with a gradual curvature, and the double-flared deflector with a gradual curvature is located between the two nested deflector components; wherein the size of the double-flared deflector with a gradual curvature is smaller than the size of the outermost double-flared deflector in the nested deflector components.

[0037] In this solution, when the size of the outermost layer of the double-horn body guide with gradual curvature in the nested guide assembly is larger, more cold air can be gathered. When the size of the double-horn body guide with gradual curvature is smaller, the cold air can be more concentrated, thereby improving the stability of the connection between the cold air and the energy source. Therefore, this solution adopts a combination of a larger nested guide assembly and a smaller double-horn body guide with gradual curvature to form a guide, so that the guide has the effect of gathering more cold air and concentrating the cold air at the same time.

[0038] In the deflector, the larger nested deflector components are placed on the outside, while the smaller, curvature-gradient dual-flare deflector components are placed on the inside. Because the larger nested deflector components are placed on the outside, they face the human body and the energy source. Therefore, the nested deflector components facing the human body can gather cold air over a larger area, while the nested deflector components facing the energy source can connect the cold air with the energy source over a larger area, allowing for full contact between the cold air and the energy source, thus making the connection between the two more stable. The smaller, curvature-gradient dual-flare deflector components located inside the deflector can further gather and concentrate the passing cold air, preventing it from being interrupted during its movement within the deflector.

[0039] The present application also discloses a device for dispelling cold air, which includes a mobile component, an energy source and the nested guide component as described above, wherein the energy source and the nested guide component are fixed on the mobile component, and one large end of the double-horn guide component with a gradual curvature in the nested guide component is used to face the human body, and the other large end of the double-horn guide component with a gradual curvature is used to face the energy source.

[0040] In this solution, the nested diversion components, combined with the guiding effect of the cooling element, prevent the cold air from being disconnected from the energy source while controlling the device's movement away. This allows the cold air to be continuously drawn out of the user's body, effectively eliminating the cold. This product eliminates the need for manual operation and does not require professional assistance; ordinary users can use it independently. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0066] 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.

[0067] The present application is described in detail below with reference to the accompanying drawings and optional embodiments.

[0068] Example 1:

[0069] Figure 1 is a schematic diagram of a nested guide assembly provided in the first embodiment of the present application. As shown in Figure 1, the nested guide assembly 300 provided in the first embodiment of the present application is a two-stage single-nested guide assembly, specifically including two stages of curvature gradient double-horn guide parts, and the number of curvature gradient double-horn guide parts in each stage is only one.

[0070] Specifically, the nested guide assembly 300 in the embodiment of the present application is formed by nesting a first curvature gradient double-flare guide piece 310 and a second curvature gradient double-flare guide piece 320. The size of the first curvature gradient double-flare guide piece 310 is smaller than the size of the second curvature gradient double-flare guide piece 320, and the first curvature gradient double-flare guide piece 310 is nested in the second curvature gradient double-flare guide piece 320; moreover, along the central axis direction of the second curvature gradient double-flare guide piece 320, the channel of the first curvature gradient double-flare guide piece 310 and the channel of the second curvature gradient double-flare guide piece 320 completely overlap at the narrowest through-hole position.

[0071] 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 310 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 320, and does not mean that the two positions have the same size and the edges overlap.

[0072] As for the shapes of the first curvature gradient double-horn body flow guide 310 and the second curvature gradient double-horn body flow guide 320, refer to Figure 2, which is a three-dimensional schematic diagram of a curvature gradient double-horn body flow guide. It can be seen from Figure 2 that the channel shape of the curvature gradient double-horn body flow guide 21 is a double-horn shape, which includes a first horn 22 and a second horn 23. The first horn 22 and the second horn 23 are of the same size and shape, and the first horn 22 and the second horn 23 are axially symmetrical.

[0073] The first horn 22 includes a large end 22a and a small end 22b. The second horn 23 also includes a large end 22a and a small end 22b. The diameter of the large end 22a of the first horn 22 is larger than the diameter of the small end 22b of the first horn 22, and the diameter of the large end 22a of the second horn 23 is larger than the diameter of the small end 22b of the second horn 23. The small end 22b of the first horn 22 and the small end 22b of the second horn 23 are connected to form a double-horn-shaped channel. Furthermore, the small end 22b of the first horn 22 and the small end 22b of the second horn 23 are directly connected, with a smooth transition without abrupt changes or sharp corners.

[0074] As shown in Figure 3, Figure 3 is a schematic diagram of the surface change law of the inner wall of the double-horn body air guide with a gradual curvature. The cross-sectional line of the inner wall of the first horn 22 and the second horn 23 along the central axis of the double-horn body air guide is taken as arc s. The arc s is concave toward the central axis, and the curvature of the arc increases from the large-mouth end 22a of the first horn 22 and the second horn 23 to the corresponding small-mouth end 22b; the arc extends toward the large-mouth end 22a, and the curvature tends to zero; the tangent of the arc corresponding to the endpoint of the large-mouth end 22a of the first horn 22 tends to be perpendicular to the central axis; the arc approaches the central axis toward the small-mouth end 22b of the first horn 22, but does not intersect.

[0075] As shown in FIG4 , FIG4 is a schematic outline diagram of another dual-flare flow guide with a gradually varying curvature. The dual-flare flow guide 21 includes, in addition to an axisymmetrically arranged first flare 22 and second flare 23, a throat 24. The small-mouth end 22b of the first flare 22 and the small-mouth end 22b of the second flare 23 are connected by the throat 24. The small-mouth ends of the first and second flares 22 and 23 smoothly transition into the throat 24. The throat 24 is hollow inside and open at both ends, forming a cylindrical shape.

[0076] The throat 24 can be cylindrical with uniform cross-sectional dimensions throughout, and its cross section is a straight line parallel to the central axis. This allows cold air to flow from the first speaker 22 to the second speaker 23 along the same axis, effectively guiding the cold air. Because the interiors of the first and second speakers 22, 23 are concave arcs, the length of the throat 24 is minimized. This allows for smoother guidance of the cold air from the first speaker 22, through the throat 24, to the second speaker 23, thereby enhancing the effectiveness of guiding the cold air. In this case, the narrowest through-hole of the first and second gradually curvature dual-speaker flow guides 310, 320 corresponds to the cross-section of any point on the throat 24.

[0077] Of course, the throat 24 can also adopt an inwardly concave curved surface, with the curvature variation pattern of this curved surface different from that of the first horn 22 and the second horn 23. This will smooth the guidance of cold air within the deflector, further improving the cold air guidance effect. The length of the throat 24 can be one-tenth to one-third of the total length of the gradually curvature dual-horn deflector 21. In this case, the narrowest through-hole position of the first gradually curvature dual-horn deflector 310 and the second gradually curvature dual-horn deflector 320 corresponds to the cross-section at the center of the throat 24.

[0078] For the sake of convenience, the following text will use the curvature gradient double-horn body guide piece 21 with a throat 24 as an example for explanation, but it does not mean that the curvature gradient double-horn body guide pieces in the nested guide assembly 300 must have a throat 24, and they may not have it; when there is no throat 24, the position of the through hole of the curvature gradient double-horn body guide piece 21 at the narrowest part of the channel is the position where the small mouth ends 22b of the two horns contact.

[0079] It should be understood that in the embodiments of the present application, "nesting" means: first, the curvature gradient double horn flow guide members between different levels must meet the nesting conditions; second, the curvature gradient double horn flow guide member of the previous level must completely cover the small-sized curvature gradient double horn flow guide member. For ease of understanding, the present application provides a specific example. From the front of the nested guide assembly 300 (along the central axis of the nested guide assembly 300), the outer contour of the large end of the second curvature gradient double horn flow guide member 320 surrounds the outer contour of the large end of the first curvature gradient double horn flow guide member 310, and the large end of the first curvature gradient double horn flow guide member 310 does not exceed the range covered by the large end of the second curvature gradient double horn flow guide member 320. Viewed from the side of the nested guide assembly 300 (perpendicular to the central axis of the nested guide assembly 300), the second curvature gradient double-flare guide member 320 will completely block the first curvature gradient double-flare guide member 310, so that only the outline shape of the second curvature gradient double-flare guide member 320 can be seen in this direction.

[0080] The present application adopts a nested guide assembly 300 which is nested by a first curvature gradient double-horn body guide piece 310 and a second curvature gradient double-horn body guide piece 320. Since the second curvature gradient double-horn body guide piece 320 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 310 has a smaller opening, so that the cold air gathered through the opening of the second curvature gradient double-horn body guide piece 320 enters the first curvature gradient double-horn body guide piece 310, and through secondary guidance, it can enhance the attraction of the cold air and allow the cold air to pass through the nested guide assembly 300 more stably; at the same time, since the first curvature gradient double-horn body guide piece 310 has a smaller throat, the cold air can be more concentrated. After adopting the nested guide assembly 300, the attraction formed by the double guidance brought by the second curvature gradient double horn body guide piece 320 and the first curvature gradient double horn body guide piece 310 is sufficient to allow more concentrated cold air to pass through the throat and neck of the first curvature gradient double horn body guide piece 310, and then drive the deeper cold air of the human body out into the nested guide assembly 300, which can better clear the root cause of the cold air and make the cold air eliminated more thoroughly, thereby improving the health level of the human body.

[0081] Furthermore, the nested guide assembly 300 in the embodiment of the present application uses a two-stage nested curvature gradient double-horn guide member, which is easy to manufacture and has low cost. Furthermore, the entire nested guide assembly 300 is relatively small in size, making it suitable for removing cold air from a specific part of the human body.

[0082] In the embodiment of the present application, the center points of the first and second curvature gradient dual-flared body guides 310 and 320 coincide. With this design, the first and second curvature gradient dual-flared body guides 310 and 320 converge toward the same central location for the cold air, concentrating the cold air and thereby drawing out the cold air from deeper levels. Furthermore, only one first curvature gradient dual-flared body guide 310 is nested within the second curvature gradient dual-flared body guide 320, and the large mouth of the first curvature gradient dual-flared body guide 310 is close to the throat of the second curvature gradient dual-flared body guide 320. This creates a more natural arcuate transition between the first and second curvature gradient dual-flared body guides 310 and 320, making the process of drawing out the cold air less susceptible to interference.

[0083] As shown in Figure 5, in this embodiment of the present application, the central axis of the first gradually-curved dual-flared air guide 310 coincides with the central axis of the second gradually-curved dual-flared air guide 320. With this design, the second gradually-curved dual-flared air guide 320 and the first gradually-curved dual-flared air guide 310 converge toward the same straight line, directing the cold air along the same straight line. This ensures stable cold air guidance and reduces the risk of interference from the outside environment.

[0084] In the embodiment of the present application, the first gradually-varying dual-flared air guide 310 is a scaled-down version of the second gradually-varying dual-flared air guide 320. Because the two gradually-varying dual-flared air guides have the same shape and good consistency, and the inner wall curves of the two gradually-varying dual-flared air guides transition naturally, the cold air is guided more smoothly.

[0085] As shown in Figures 6 and 7, there is an air duct 301 between the first curvature gradient double-flare body guide piece 310 and the second curvature gradient double-flare body guide piece 320. The two ends of the air duct 301 are respectively connected to the outside of the two ends of the nested guide assembly 300, so that the gas can pass between the outer side of the first curvature gradient double-flare body guide piece 310 and the inner side of the second curvature gradient double-flare body guide piece 320.

[0086] Since there is an air duct 301 between the two levels of curvature gradient double-horn body air guide pieces, the first curvature gradient double-horn body air guide piece 310 does not block the throat in the middle of the second curvature gradient double-horn body air guide piece 320, that is, the first horn 22 and the second horn 23 of the second curvature gradient double-horn body air guide piece 320 are still connected, and the second curvature gradient double-horn body air guide piece 320 still retains sufficient cold air guiding ability, which can attract cold air into its interior, and then guide the cold air into the second curvature gradient double-horn body air guide piece 320, thereby enhancing the guiding effect of cold air.

[0087] For the air duct 301, since the curvature gradient double trumpet body guide piece is a double trumpet-shaped structure with wide ends and narrow middle, when the first curvature gradient double trumpet body guide piece 310 is placed in the channel of the second curvature gradient double trumpet body guide piece 320, since the center points of the first curvature gradient double trumpet body guide piece 310 and the second curvature gradient double trumpet body guide piece 320 coincide with each other, the two large mouth ends of the first curvature gradient double trumpet body guide piece 310 are respectively located at the second curvature gradient double trumpet body guide piece 320. On both sides of the center point, the first curvature gradient double-flare body flow guide 310 needs to be moved through the minimum through-hole of the channel of the second curvature gradient double-flare body flow guide 320. Therefore, the large mouth end size of the first curvature gradient double-flare body flow guide 310 will be smaller than the minimum through-hole aperture of the channel of the second curvature gradient double-flare body flow guide 320, that is, the minimum cross-sectional size of the throat. At this time, an airway 301 will naturally be formed between the first curvature gradient double-flare body flow guide 310 and the second curvature gradient double-flare body flow guide 320.

[0088] Moreover, there is no direct contact between the first curvature gradient double-flare flow guide 310 and the second curvature gradient double-flare flow guide 320. The large-mouth edges at both ends of the first curvature gradient double-flare flow guide 310 are glued and fixed to the inner wall of the second curvature gradient double-flare flow guide 320 by dispensing glue, so that the center lines of the first curvature gradient double-flare flow guide 310 and the second curvature gradient double-flare flow guide 320 coincide.

[0089] Optionally, the large-mouth edges at both ends of the first curvature gradient double-flare body guide member 310 are fixed to the inner wall of the second curvature gradient double-flare body guide member 320 through three glue spots 302, and the angle between two adjacent glue spots 302 is 120°. While ensuring the stability between the first curvature gradient double-flare body guide member 310 and the second curvature gradient double-flare body guide member 320, the area of ​​the airway 301 is avoided from being reduced, which would affect the ability of the second curvature gradient double-flare body guide member 320 to guide cold air.

[0090] 8 , the distance a between the wide-mouth end of the second curvature gradient double-flared flow guide 320 and the corresponding wide-mouth end of the first curvature gradient double-flared flow guide 310 exceeds one-quarter of the length L of the second curvature gradient double-flared flow guide 320 .

[0091] In this solution, after the first curvature gradient double-horn body air guide 310 is nested into the channel of the second curvature gradient double-horn body air guide 320, the end face of the large mouth end of the second curvature gradient double-horn body air guide 320 exceeds half the length of the single-sided horn in the first curvature gradient double-horn body air guide 310, thereby preventing the end of the first curvature gradient double-horn body air guide 310 from protruding too much, resulting in the cold air gathered by the second curvature gradient double-horn body air guide 320 not being easily introduced into the internal channel of the first curvature gradient double-horn body air guide 310.

[0092] Furthermore, the distance between the wide-mouth end of the first gradually-curved double-flared air guide 310 and the corresponding wide-mouth end of the second gradually-curved double-flared air guide 320 may also exceed one-third of the length of the second gradually-curved double-flared air guide 320. Because the distance between the end of the first gradually-curved double-flared air guide 310 and the corresponding end of the second gradually-curved double-flared air guide 320 is greater, the distance between the end of the first gradually-curved double-flared air guide 310 and the inner wall of the second gradually-curved double-flared air guide 320 is smaller, resulting in a more natural transition between the end of the first gradually-curved double-flared air guide 310 and the inner wall of the second gradually-curved double-flared air guide 320, and a smoother cold air guiding process.

[0093] It should be noted that in the embodiment of the present application, when viewed along the central axis of the second curvature gradient double-horn body guide member 320, it is also feasible that the through hole at the narrowest part of the channel of the first curvature gradient double-horn body guide member 310 only partially overlaps with the through hole at the narrowest part of the channel of the second curvature gradient double-horn body guide member 320. Similarly, the attraction formed by the double guidance brought by the second curvature gradient double-horn body guide member 320 and the first curvature gradient double-horn body guide member 310 can be utilized to allow more concentrated cold air to pass through the throat of the first curvature gradient double-horn body guide member 310, and then drive the deeper cold air of the human body out into the nested guide assembly 300. However, due to the offset between the throat of the first curvature gradient double-horn body guide member 310 and the throat of the second curvature gradient double-horn body guide member 320, the stability of the cold air after passing through the nested guide assembly 300 will be slightly poor.

[0094] At this time, the center points of the first curvature gradient double-horn body flow guide 310 and the second curvature gradient double-horn body flow guide 320 do not coincide, and the center lines do not coincide. Even the first curvature gradient double-horn body flow guide 310 may not be a proportional scaled part of the second curvature gradient double-horn body flow guide 320. As long as the first curvature gradient double-horn body flow guide 310 can be nested inside the channel of the second curvature gradient double-horn body flow guide 320, it should fall within the protection scope of this application.

[0095] Example 2:

[0096] As shown in FIG9 , the second embodiment provided by the present application differs from the first embodiment in that the present embodiment adopts a three-level nested nested guide assembly, which is a three-level single nested guide assembly. Specifically, the nested guide assembly 300 includes a third curvature gradient double-flared body guide member 330, a fourth curvature gradient double-flared body guide member 340, and a fifth curvature gradient double-flared body guide member 350. The third curvature gradient double-flared body guide member 330 is nested within the fourth curvature gradient double-flared body guide member 340, which is nested within the fifth curvature gradient double-flared body guide member 350. Furthermore, when viewed along the central axis of the fifth curvature gradient double-flared body guide member 350, the through-holes of the third curvature gradient double-flared body guide member 330, the fourth curvature gradient double-flared body guide member 340, and the fifth curvature gradient double-flared body guide member 350 overlap at the narrowest point of the channel.

[0097] In the embodiment of the present application, the nested guide assembly 300 is formed by nesting three dual-flare guides of unequal sizes with gradually varying curvatures. As the number of levels in the nested guide assembly 300 increases, the nesting becomes more numerous, resulting in a larger outermost dual-flare guide and a smaller innermost dual-flare guide. This allows for a larger opening area and a smaller throat diameter, improving the guiding effect of the nested guide assembly 300. However, as the number of nesting levels increases, the size of the nested guide assembly 300 increases significantly, impacting practical use. Therefore, to avoid excessive size of the nested guide assembly 300 while improving its guiding effect, the nested guide assembly 300 is designed as a three-layer nested structure consisting of a third dual-flare guide 330 with gradually varying curvatures, a fourth dual-flare guide 340 with gradually varying curvatures, and a fifth dual-flare guide 350 with gradually varying curvatures.

[0098] Moreover, in the embodiment of the present application, the third curvature gradient double horn body air guide 330, the fourth curvature gradient double horn body air guide 340 and the fifth curvature gradient double horn body air guide 350, the center points of these three curvature gradient double horn body air guides coincide, the central axes coincide, and the third curvature gradient double horn body air guide 330 is a scaled version of the fourth curvature gradient double horn body air guide 340, and the fourth curvature gradient double horn body air guide 340 is a scaled version of the fifth curvature gradient double horn body air guide 350, so as to ensure that in the nested guide assembly 300, the convergence direction of the cold air tends to the same straight line, and the arc transition of the cold air between two adjacent curvature gradient double horn body guides is more natural, so that the nested guide assembly 300 has good stability in guiding the cold air and is not easily disturbed by the external environment.

[0099] In addition, there is an air duct 301 between two adjacent levels of curvature gradient double-horn body guide pieces. Specifically, there is an air duct 301 between the third curvature gradient double-horn body guide piece 330 and the fourth curvature gradient double-horn body guide piece 340, and there is also an air duct 301 between the fourth curvature gradient double-horn body guide piece 340 and the fifth curvature gradient double-horn body guide piece 350.

[0100] As for the specific formation of the air duct 301, due to the requirements of the assembly method, the third curvature gradient double-flare body flow guide 330 must be inserted into the channel of the fourth curvature gradient double-flare body flow guide 340, and the fourth curvature gradient double-flare body flow guide 340 must be inserted into the channel of the fifth curvature gradient double-flare body flow guide 350. Therefore, the large mouth end size of the third curvature gradient double-flare body flow guide 330 is smaller than the narrowest size of the channel of the fourth curvature gradient double-flare body flow guide 340, and the large mouth end size of the fourth curvature gradient double-flare body flow guide 340 is smaller than the narrowest size of the channel of the fifth curvature gradient double-flare body flow guide 350. Since there is no contact between the third curvature gradient double horn body flow guide piece 330 and the fourth curvature gradient double horn body flow guide piece 340, and there is no contact between the fourth curvature gradient double horn body flow guide piece 340 and the fifth curvature gradient double horn body flow guide piece 350, two adjacent curvature gradient double horn body flow guide pieces are fixed by several glue spots 302, thereby forming an air duct 301 between the third curvature gradient double horn body flow guide piece 330 and the fourth curvature gradient double horn body flow guide piece 340, and forming an air duct 301 between the fourth curvature gradient double horn body flow guide piece 340 and the fifth curvature gradient double horn body flow guide piece 350.

[0101] With the above design, the third curvature gradient double horn body air guide 330 will not block the throat of the fourth curvature gradient double horn body air guide 340, and the third curvature gradient double horn body air guide 330 and the fourth curvature gradient double horn body air guide 340 will not block the throat of the fifth curvature gradient double horn body air guide 350. Therefore, the fourth curvature gradient double horn body air guide 340 and the fifth curvature gradient double horn body air guide 350 still retain sufficient cold air guiding capabilities, which can attract cold air into their interiors, and then guide the cold air into the next level curvature gradient double horn body air guide, thereby enhancing the cold air guiding effect.

[0102] At the same time, in an embodiment of the present application, the distance between the large mouth end of the third curvature gradient double horn body air guide 330 and the corresponding large mouth end of the fourth curvature gradient double horn body air guide 340 exceeds one third of the length of the fourth curvature gradient double horn body air guide 340; the distance between the large mouth end of the fourth curvature gradient double horn body air guide 340 and the corresponding large mouth end of the fifth curvature gradient double horn body air guide 350 exceeds one third of the length of the fifth curvature gradient double horn body air guide 350.

[0103] Through the above design, it is possible to prevent the end of the third curvature gradient double-horn body guide member 330 from protruding too much from the interior of the fourth curvature gradient double-horn body guide member 340, and to prevent the end of the fourth curvature gradient double-horn body guide member 340 from protruding too much from the interior of the fifth curvature gradient double-horn body guide member 350, resulting in the cold air gathered by the curvature gradient double-horn body guide member of the previous level not being easily introduced into the internal channel of the curvature gradient double-horn body guide member of the next level.

[0104] Of course, after testing, only the distance between the large mouth end of the third curvature gradient double-horn body guide member 330 and the corresponding large mouth end of the fourth curvature gradient double-horn body guide member 340 is increased to exceed one quarter of the length of the fourth curvature gradient double-horn body guide member 340; only the distance between the large mouth end of the fourth curvature gradient double-horn body guide member 340 and the corresponding large mouth end of the fifth curvature gradient double-horn body guide member 350 is increased to exceed one quarter of the length of the fifth curvature gradient double-horn body guide member 350, which also does not affect the introduction of cold air into the internal channel of the curvature gradient double-horn body guide member of the next level.

[0105] It should be noted that in the embodiment of the present application, the through holes of the third curvature gradient double horn body air guide 330, the fourth curvature gradient double horn body air guide 340 and the fifth curvature gradient double horn body air guide 350 at the narrowest part of the channel may only partially overlap. At this time, the central axes and center points of the third curvature gradient double horn body air guide 330, the fourth curvature gradient double horn body air guide 340 and the fifth curvature gradient double horn body air guide 350 do not coincide, but as long as the nested design is met, the cold air of the user to be removed can also be continuously and stably drawn out, thereby achieving a good effect of removing the cold air, and also meeting the protection effect of the present application.

[0106] Alternatively, in the nested guide assembly 300, only two double-flared guide members with gradually varying curvature have completely overlapping through-holes at the narrowest part of the channel, which can also achieve the above-mentioned effect and is within the protection scope of this application.

[0107] It should be noted that in the present application, while there is only one double-horn body guide member with a gradual curvature at each level, the nested guide assembly 300 can also adopt a design of more than four levels, that is, the nested guide assembly 300 is composed of more than four double-horn body guide members with a gradual curvature of different sizes nested together. The specific number design can be adjusted accordingly according to actual needs. As for the design of the corresponding nested guide assembly 300, reference can be made to the overall design of the nested guide assembly 300 and the specific design of the two adjacent levels of gradual curvature double-horn body guide members in the first and second embodiments. As long as the condition of "looking along the central axis direction of the double-horn body guide member with a gradual curvature at the previous level, the through holes of the double-horn body guide member with a gradual curvature at the previous level and the double-horn body guide member with a gradual curvature at the next level at the narrowest part of the channel at least partially overlap" is met, it will not be explained in detail here.

[0108] Example 3:

[0109] As shown in Figure 10, as the third embodiment provided by the present application, the difference from the above embodiment is that in the embodiment of the present application, the number of the curvature gradient double-horn body guide members in the next level is two. Specifically, the nested guide assembly 300 adopts a two-stage double-nested guide assembly, including a first-stage curvature gradient double-horn body guide member 360 and a second-stage curvature gradient double-horn body guide member 370. The number of the first-stage curvature gradient double-horn body guide members 360 is one, and the number of the second-stage curvature gradient double-horn body guide members 370 is two; the two second-stage curvature gradient double-horn body guide members 370 are nested side by side in the first-stage curvature gradient double-horn body guide member 360, there is no gap between the two second-stage curvature gradient double-horn body guide members 370, and the through holes of the two second-stage curvature gradient double-horn body guide members 370 at the narrowest part of the channel overlap with the through holes of the first-stage curvature gradient double-horn body guide member 360 at the narrowest part of the channel.

[0110] In an embodiment of the present application, since two second-stage curvature gradient double-horn body flow guide members 370 are nested inside a first-stage curvature gradient double-horn body flow guide member 360, the two second-stage curvature gradient double-horn body flow guide members 370 are connected in series inside the channel of the first-stage curvature gradient double-horn body flow guide member 360, and there is no gap between the two second-stage curvature gradient double-horn body flow guide members 370. After the cold air passes through the two second-stage curvature gradient double-horn body guide pieces 370 connected in series, the cold air will be more concentrated and more directed; moreover, since the two second-stage curvature gradient double-horn body guide pieces 370 connected in series are nested with the first-stage curvature gradient double-horn body guide piece 360, under the guidance of the first-stage curvature gradient double-horn body guide piece 360, the cold air will not be retained between the two second-stage curvature gradient double-horn body guide pieces 370 connected in series. The cold air can pass through the nested guide assembly 300 in a more concentrated manner, further improving the stability of the cold air outflow while ensuring that the cold air can smoothly pass through the second-stage curvature gradient double-horn body guide piece 370.

[0111] Moreover, if too many second-stage curvature gradient double-horn body guide pieces 370 are nested inside the first-stage curvature gradient double-horn body guide piece 360, the second-stage curvature gradient double-horn body guide piece 370 will protrude too much from the throat of the first-stage curvature gradient double-horn body guide piece 360, that is, the large mouth end of the second-stage curvature gradient double-horn body guide piece 370 located at the edge will be closer to the large mouth end of the first-stage curvature gradient double-horn body guide piece 360, resulting in the cold air being gathered by the large mouth end of the first-stage curvature gradient double-horn body guide piece 360, and not being easily guided into the interior of the second-stage curvature gradient double-horn body guide piece 370. Therefore, only two second-stage curvature gradient double-flare body flow guide pieces 370 are nested inside the first-stage curvature gradient double-flare body flow guide piece 360, so that the large mouth end of the second-stage curvature gradient double-flare body flow guide piece 370 at the edge is far away from the large mouth end of the first-stage curvature gradient double-flare body flow guide piece 360, and the cold air is more easily guided into the channel of the second-stage curvature gradient double-flare body flow guide piece 370.

[0112] In this embodiment, the two second-stage, gradually-varying, dual-flared air guides 370 have identical dimensions and shapes, preventing sudden changes in the flow of cold air within the same dual-flared air guide. Furthermore, the opposing large-mouth edges of the two second-stage, gradually-varying, dual-flared air guides 370 are bonded together to prevent cold air from escaping between them.

[0113] Furthermore, the two second-stage curvature gradient double-horn body guide pieces 370 are both proportionally scaled parts of the first-stage curvature gradient double-horn body guide piece 360, so that the two-stage curvature gradient double-horn body guide pieces have good consistency due to the same contour shape, and the transition from the inner wall curve of the first-stage curvature gradient double-horn body guide piece 360 ​​to the inner wall curve of the second-stage curvature gradient double-horn body guide piece 370 is more natural, and the cold air guiding process is smoother.

[0114] In the nested guide assembly 300 provided in the embodiment of the present application, the central axes of the three double-horn guide members with gradual curvature are all coincident, so that the convergence direction of the cold air of all the double-horn guide members with gradual curvature tends to be in the same straight line, so that the cold air is guided out along the same straight line, so that the cold air guidance is stable and not easily disturbed by the external environment.

[0115] At the same time, in the first-stage curvature gradient double-horn body guide piece 360, the fitting position between the two second-stage curvature gradient double-horn body guide pieces 370 is located at the center point of the first-stage curvature gradient double-horn body guide piece 360, that is, the narrowest part of the throat of the first-stage curvature gradient double-horn body guide piece 360, but the two second-stage curvature gradient double-horn body guide pieces 370 do not block the channel of the first-stage curvature gradient double-horn body guide piece 360, so that there is an airway 301 between the first-stage curvature gradient double-horn body guide piece 360 ​​and the second-stage curvature gradient double-horn body guide piece 370.

[0116] Among them, the width of the air duct 301, that is, the distance between the first-stage curvature gradient double-horn body guide 360 ​​and the second-stage curvature gradient double-horn body guide 370 is 0.5-2mm. Through experimental tests, the width of the air duct 301 in this width range can enable the first-stage curvature gradient double-horn body guide 360 ​​to still retain sufficient cold air guiding ability, and can attract cold air into its interior, and then guide the cold air into the second-stage curvature gradient double-horn body guide 370, thereby enhancing the cold air guiding effect.

[0117] As a method for forming airway 301, as shown in Figure 14, the area of ​​the wide-mouth end of the second-stage, gradually changing curvature, double-flared flow guide 370 is smaller than the area of ​​the smallest throat of the first-stage, gradually changing curvature, double-flared flow guide 360, i.e., the size of the through-hole at the smallest point of the passage. The two second-stage, gradually changing curvature, double-flared flow guides 370 are fixed to the interior of the first-stage, gradually changing curvature, double-flared flow guide 360 ​​by glue at their joints. Three specific glue points 302 are sufficient, with the angle between adjacent glue points 302 being 120°. This ensures stability while also reducing the area of ​​airway 301 between two adjacent gradually changing curvature, double-flared flow guides. Depending on the actual situation, the number of glue points 302 can be increased or decreased, or even the fixing method can be changed, such as by using clamping or welding.

[0118] As another method of forming the air channel 301, as shown in Figures 12 and 13, a plurality of guiding warps 361 and a plurality of guiding wefts 362 are provided on the inner wall of a first-stage, curvature-gradient, double-flared flow guide 360. The plurality of guiding warps 361 extend from one opening of the channel toward the other opening of the channel, and the plurality of guiding wefts 362 surround the central axis of the channel and are spaced apart along the central axis. Furthermore, the guiding warps 361 and guiding wefts 362 are both groove structures, forming the air channel 301. The addition of the guiding warps 361 and guiding wefts 362 can make the guidance of the cold air more directional, resulting in a better guiding effect.

[0119] In this embodiment, the wide-mouth edge of the second-stage, gradually-varying-curvature, double-flared-body flow guide 370 can abut against the inner wall of the first-stage, gradually-varying-curvature, double-flared-body flow guide 360. Due to the presence of the guide warp threads 361 and the guide weft threads 362, the third-stage, gradually-varying-curvature, double-flared-body flow guide 380 cannot block the corresponding internal passage of the second-stage, gradually-varying-curvature, double-flared-body flow guide 370, and the second-stage, gradually-varying-curvature, double-flared-body flow guide 370 cannot block the internal passage of the first-stage, gradually-varying-curvature, double-flared-body flow guide 360. The guide warp threads 361 and the guide weft threads 362 form an airway 301, allowing cold air to pass through them. Furthermore, the guide warp threads 361 and the guide weft threads 362 limit and guide the glue during the dispensing process, preventing the glue from converging and blocking the gaps.

[0120] In addition, as shown in Figure 14, the distance a between the outer ends of the two second-stage curvature gradient double-flare body guide members 370, that is, the large-mouth ends away from the center point of the first-stage curvature gradient double-flare body guide member 360, and the corresponding large-mouth ends of the first-stage curvature gradient double-flare body guide member 360, exceeds one-quarter of the length L of the first-stage curvature gradient double-flare body guide member 360.

[0121] The above design avoids the problem of the end of the second-stage, gradually-varying-curvature, double-flared-body flow guide 370 protruding too far, which could hinder the flow of cold air gathered by the first-stage, gradually-varying-curvature, double-flared-body flow guide 360 ​​into the internal passage of the second-stage, gradually-varying-curvature, double-flared-body flow guide 370. Furthermore, the distance between the outer end of the second-stage, gradually-varying-curvature, double-flared-body flow guide 370 and the corresponding wide-mouth end of the first-stage, gradually-varying-curvature, double-flared-body flow guide 360 ​​can be increased to exceed one-third the length of the first-stage, gradually-varying-curvature, double-flared-body flow guide 360, as needed.

[0122] Example 4:

[0123] As shown in FIG15 , the fourth embodiment provided by the present application differs from the third embodiment in that the nested guide assembly 300 in the present embodiment adopts a three-level nesting arrangement, forming a three-level double-nested guide assembly. Specifically, the nested guide assembly 300 includes a first-level double-flared guide member 360 with a gradual curvature, a second-level double-flared guide member 370 with a gradual curvature, and a third-level double-flared guide member 380 with a gradual curvature. There is one first-level double-flared guide member 360, two second-level double-flared guide members 370 with a gradual curvature, and four third-level double-flared guide members 380 with a gradual curvature. Two third-level double-flared guide members 380 are nested side by side within one second-level double-flared guide member 370, and two second-level double-flared guide members 370 are nested side by side within the first-level double-flared guide member 360 with a gradual curvature.

[0124] Moreover, the edges of the large mouth ends of the two third-stage curvature gradient double-horn body guide pieces 380 located inside the same second-stage curvature gradient double-horn body guide piece 370 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 370 located inside the first-stage curvature gradient double-horn body guide piece 360 ​​fit together without a gap.

[0125] Since the more nested layers within the nested guide assembly 300, the better the guiding effect, but this will result in a larger volume and higher cost for the nested guide assembly 300, a three-layer nested design is more suitable, comprising a first-stage, gradually-varying-curvature, double-flared guide member 360, a second-stage, gradually-varying-curvature, double-flared guide member 370, and a third-stage, gradually-varying-curvature, double-flared guide member 380. Therefore, the nested guide assembly 300 in the embodiment of the present application preferably adopts a three-layer nested design. For ease of explanation, the embodiments of the present application are described using this three-layer nested implementation.

[0126] Similarly, in the embodiment of the present application, the size and shape of the double-horn body guide pieces with a gradient curvature at the same level are the same, so as to avoid the problem of sudden changes when the cold air flows inside the double-horn body guide pieces with a gradient curvature at the same level.

[0127] Similar to the previous embodiment, in the nested guide assembly 300, the central axes of all the curvature gradient double-horn body guide members are coincident, the third-stage curvature gradient double-horn body guide member 380 is a scaled version of the second-stage curvature gradient double-horn body guide member 370, and the second-stage curvature gradient double-horn body guide member 370 is a scaled version of the first-stage curvature gradient double-horn body guide member 360.

[0128] In the first-stage curvature gradient double-flare body guide piece 360, the fitting position between the two second-stage curvature gradient double-flare body guide pieces 370 is located at the center point of the first-stage curvature gradient double-flare body guide piece 360, that is, the narrowest part of the throat of the first-stage curvature gradient double-flare body guide piece 360, but the two second-stage curvature gradient double-flare body guide pieces 370 do not block the passage of the first-stage curvature gradient double-flare body guide piece 360, so that there is an airway 301 between the first-stage curvature gradient double-flare body guide piece 360 ​​and the second-stage curvature gradient double-flare body guide piece 370. Similarly, in the second-stage curvature gradient double-horn body guide piece 370, the fitting position between the two third-stage curvature gradient double-horn body guide pieces 380 is located at the center point of the corresponding second-stage curvature gradient double-horn body guide piece 370, that is, the narrowest part of the throat of the second-stage curvature gradient double-horn body guide piece 370, and the two third-stage curvature gradient double-horn body guide pieces do not block the channel of the corresponding second-stage curvature gradient double-horn body guide piece 370, so that there is an airway 301 between the second-stage curvature gradient double-horn body guide piece 370 and the corresponding third-stage curvature gradient double-horn body guide piece 380.

[0129] For the design of the air passage 301 , please refer to the third embodiment for details, and no further details will be given here.

[0130] In the embodiment of the present application, in each second-stage double-flared-body flow guide 370 with a gradual curvature, the distance between the outer ends of the two third-stage double-flared-body flow guides 380, i.e., the ends with the wide openings away from the center point of the second-stage double-flared-body flow guide 370, and the corresponding ends with the wide openings of the second-stage double-flared-body flow guide 370, exceeds one-quarter the length of the second-stage double-flared-body flow guide 370. Similarly, the distance between the outer ends of the two second-stage double-flared-body flow guides 370, i.e., the ends with the wide openings away from the center point of the first-stage double-flared-body flow guide 360, and the corresponding ends with the wide openings of the first-stage double-flared-body flow guide 360, exceeds one-quarter the length of the first-stage double-flared-body flow guide 360.

[0131] The above design can avoid the problem of the end of the next-stage gradually-varying double-flared body guide being too protruding, which would prevent the cold air gathered by the previous-stage gradually-varying double-flared body guide from being easily guided into the internal channel of the next-stage gradually-varying double-flared body guide. Furthermore, as needed, the distance between the outer end of the third-stage gradually-varying double-flared body guide 380 and the corresponding wide-mouth end of the second-stage gradually-varying double-flared body guide 370 can be increased to exceed one-third of the length of the second-stage gradually-varying double-flared body guide 370; and the distance between the outer end of the second-stage gradually-varying double-flared body guide 370 and the corresponding wide-mouth end of the first-stage gradually-varying double-flared body guide 360 ​​can be increased to exceed one-third of the length of the first-stage gradually-varying double-flared body guide 360.

[0132] It should be noted that, in the present application, the nested guide assembly 300 can also adopt a design of more than four levels, that is, the nested guide assembly 300 is formed by nesting more than four levels of curvature gradient double-horn body guide members, and each upper-level curvature gradient double-horn body guide member can be nested with more than three lower-level curvature gradient double-horn body guide members. The specific selection is made according to needs. The specific design refers to the specific design of the nested guide assembly 300 as a whole and the adjacent two-level curvature gradient double-horn body guide members in the embodiment of the present application, and no further details will be given here.

[0133] Embodiment 5:

[0134] As the fifth embodiment of the present application, the embodiment of the present application further provides a deflector, wherein the deflector 20 includes at least one nested deflector assembly 300 in the above embodiments.

[0135] As shown in FIG. 16 , as an embodiment of a deflector 20 , the deflector 20 is composed of two nested deflector components 300 and an independent double-flare deflector 21 with a gradual curvature. The double-flare deflector 21 with a gradual curvature is located between the two nested deflector components 300 .

[0136] In this embodiment, each nested guide assembly 300 can bring about the attraction formed by at least two layers of guidance, which is sufficient to allow more concentrated cold air to pass through the throat of the next-level double-horn guide member with a gradual curvature. The combination of the two nested guide assemblies 300 can better clear the root cause of the cold air.

[0137] Combined with an independent double-horn body guide member 21 with a gradual curvature, two nested guide assemblies 300 and an independent double-horn body guide member 21 with a gradual curvature are connected in series to form a guide device 20, so that the cold air can be subjected to multiple convergence effects, and ultimately less cold air is dispersed, the connection with the energy source 200 is stronger, and the stability is better, thereby effectively ensuring the effect of removing the cold air.

[0138] Furthermore, the size of the double-flared flow guide member 21 with a gradually varying curvature is smaller than the size of the outermost double-flared flow guide member with a gradually varying curvature in the two nested flow guide assemblies 300 .

[0139] In the deflector 20, the larger nested deflector assembly 300 is placed on the outside, and the smaller, curvature-gradient dual-horn deflector 21 is placed on the inside. This positions the larger, curvature-gradient dual-horn deflector opposite the human body and the energy source 200. Therefore, the nested deflector assembly 300 facing the human body can gather cold air over a wider range, while the nested deflector assembly 300 facing the energy source 200 allows the cold air to establish contact with the energy source 200 over a wider range, ensuring full contact between the cold air and the energy source 200, thereby making the connection between the two more stable. The smaller, curvature-gradient dual-horn deflector 21 located inside the deflector 20 can further gather and concentrate the cold air passing through it, making it less likely to be interrupted while moving within the deflector 20.

[0140] In this embodiment, the central axes of the two nested flow guide assemblies 300 and the gradually-varying-curvature dual-flared flow guide coincide, and the two nested flow guide assemblies 300 are identical in size and shape. The gradually-varying-curvature dual-flared flow guide 21 located between the two nested flow guide assemblies 300 is a scaled-down version of the outermost gradually-varying-curvature dual-flared flow guide in the nested flow guide assemblies 300. Furthermore, the gradually-varying-curvature dual-flared flow guide 21 is equidistant from the two nested flow guide assemblies 300. Of course, the above-described specific design can also be adjusted based on actual conditions.

[0141] As shown in Figure 17, as another embodiment of the deflector 20, the deflector 20 is composed of three nested deflector components 300, namely the first nested deflector component 25, the second nested deflector component 26 and the third nested deflector component 27, wherein the second nested deflector component 26 is located between the first nested deflector component 25 and the third nested deflector component 27, the sizes of the first nested deflector component 25 and the third nested deflector component 27 are equal, and the size of the second nested deflector component 26 is smaller than the size of the first nested deflector component 25.

[0142] In this embodiment, the combination of the three nested guide components 300 can bring greater attraction to the cold air, so that the cold air is sucked out more thoroughly, avoiding the problem of recurring symptoms.

[0143] In this embodiment, the central axes of the three nested guide components 300 coincide, and the distance between the second nested guide component 26 and the first nested guide component 25 is equal to the distance between the second nested guide component 26 and the third nested guide component 27 to ensure the stability of the cold air in the deflector 20.

[0144] It should be noted that, as shown in FIG. 18 and FIG. 19 , the deflector 20 may also be composed of only one independent double-flared deflector 21 with gradually varying curvature and one nested deflector assembly 300 , or only two nested deflector assemblies 300 of the same size.

[0145] Even more, the deflector 20 can also be composed of more than four nested deflector components 300 in series, or composed of multiple independent curvature gradient double-flare body deflectors 21 and multiple nested deflector components 300 in series, as long as the following conditions are met: when the deflector 20 is composed of curvature gradient double-flare body deflectors and nested deflector components 300, the deflector 20 includes at least one nested deflector component 300 and at least one independent curvature gradient double-flare body deflector 21, the curvature gradient double-flare body deflector 21 and the nested deflector component 300 are arranged in parallel in sequence, that is, the curvature gradient double-flare body deflector 21 and the nested deflector component 300 are connected in series, and when viewed from the side of the deflector 20 (the large mouth end of the curvature gradient double-flare body deflector), the large mouth end of the independent curvature gradient double-flare body deflector 21 at least partially overlaps with the large mouth end of the outermost curvature gradient double-flare body deflector in the nested deflector component 300. When the deflector 20 is composed of nested deflector components 300, the deflector 20 includes at least two nested deflector components 300, and the nested deflector components 300 are arranged in parallel in sequence, that is, these nested deflector components 300 are arranged in series. When viewed from the side of the deflector 20, the large mouth ends of the outermost double-flared deflectors with gradually changing curvature in two adjacent nested deflector components 300 at least partially overlap.

[0146] The specific design is selected according to actual needs and is not limited here.

[0147] In an embodiment of the present application, by arranging two or more nested guide assemblies 300 in parallel, or arranging a nested guide assembly 300 and a curvature gradient double-horn guide piece 21 in parallel, the cold air can be converged twice or more, and the tendency of the cold air to move along the axis toward the energy source 200 is stronger, making it less likely for the cold air to attenuate during movement. Compared with a single nested guide assembly 300, the cold air after the series design in this solution is converged multiple times, and the final amount of cold air that is scattered is less, and the connection between the cold air and the energy source 200 is stronger, and the stability is better. During the movement process, the secondary convergence of the latter-stage nested guide assembly 300 or the curvature gradient double-horn guide piece has a stabilizing effect on the former-stage nested guide assembly 300 or the curvature gradient double-horn guide piece 21. The former-stage nested guide assembly 300 or the curvature gradient double-horn guide piece 21 is less affected by changes in the external environment and is more stable during movement. In summary, the use of the deflector 20 can enhance the guiding effect of the cold air, while stabilizing the connection between the cold air and the energy source 200 during the movement, thereby improving the effect of removing the cold air.

[0148] Example 6:

[0149] As shown in Figures 20, 21 and 22, as the sixth embodiment provided by the present application, the embodiment of the present application also provides a cold-dispelling air device, the cold-dispelling air device 10 includes a mobile component 100, an energy source 200 and the nested guide component 300 in the above embodiment, the energy source 200 and the nested guide component 300 are fixed on the mobile component 100, and one large mouth end of the double-horn guide component with a gradual curvature in the nested guide component 300 is used to face the human body, and the other large mouth end of the double-horn guide component with a gradual curvature is used to face the energy source 200.

[0150] As needed, the cold-removing device 10 may further include a control module, which drives the moving component 100 to drive the energy source 200 to move in a direction away from the user to be cold-removed.

[0151] During the process of controlling the cold-dispelling device 10 to move away, the nested guide assembly 300 provides a guiding effect that prevents the cold air from being disconnected from the energy source 200, and can continuously guide the cold air out of the user's body, thereby achieving the effect of dispelling the cold. This product no longer requires manual operation, that is, it does not require the support of professionals, and ordinary users can use it on their own.

[0152] For ease of explanation and understanding, this embodiment of the present application uses an energy source 200 of essential oil, and a nested flow guide assembly 300 comprised of two nested, tapered, double-flared flow guides, with only one double-flared flow guide at each level. However, it should be noted that the energy source 200 in this embodiment of the present application can also be other energy forms, such as moxa sticks or moxa cones, and the nested flow guide assembly 300 in this embodiment of the present application can also adopt the designs of other embodiments.

[0153] In the embodiment of the present application, the moving assembly 100 adopts a slide rail solution, and the moving assembly 100 specifically includes a slide bar assembly 110, a support frame 120, a mounting platform 160, a belt 170, a front shell 130 and a rear shell 140. The slide assembly 110 includes two slide bars 111 and two slide bar fixing blocks, the two slide bar fixing blocks are a first slide bar fixing block 112 and a second slide bar fixing block 113; two parallel slide bars 111 are used as tracks, and the two ends of the slide bar 111 are fixed by the first slide bar fixing block 112 and the second slide bar fixing block 113 respectively; the first slide bar fixing block 112 is located below the front shell 130; the second slide bar fixing block 113 is located below the rear shell 140; a support frame 120 is used under each of the two slide bar fixing blocks to suspend the two slide bars 111 in the air to form a track, and an installation platform 160 is placed on the track, and the energy source 200 is the essential oil set in the essential oil bottle 210, and the essential oil bottle 210 and the nested guide assembly 300 are fixed to the installation platform 160 and move on the track with the installation platform 160.

[0154] On the mounting platform 160 , in order to prevent dust from falling into the nested guide assembly 300 and affecting the guide effect, a protective shell 150 is also set outside the nested guide assembly 300, and there are multiple small holes on the protective shell 150 to avoid affecting the guide effect.

[0155] A belt driven pulley is provided in the first slide bar fixing block 112; a belt driving pulley is provided in the second slide bar fixing block 113; the belt 170 is located between the two slide bars 111 and is sleeved on the belt driven pulley and the belt driving pulley; both ends are fixed on the mounting platform 160 to form a closed loop structure; the closed loop structure formed by rotating the belt 170 drives the mounting platform 160 to move on the track.

[0156] The front shell 130 is located at the end of the nested guide assembly 300 away from the energy source 200, is fixed to one end of the slide rod assembly 110, and is opposite to the nested guide assembly 300. An initial travel switch 131, a counter and a start button 132 are provided in the front shell 130. The initial travel switch 131 is located on the side of the front shell 130 facing the mounting platform 160, and is used to detect the initial position of the mounting platform 160.

[0157] The rear shell 140 is located at one end of the energy source 200 away from the nested guide assembly 300 and is fixed to the other end of the slide rod assembly 110; the rear shell 140 is provided with a control module (not shown in the figure), a motor (not shown in the figure), an end travel switch 141, a billing module, an antenna 142 and a power supply, wherein the control module is a logic circuit board structure.

[0158] The power supply can be an external power adapter, which can directly convert the mains electricity into the working voltage required by the mobile component 100, and then connect it to the power input terminal of the billing module through a wire. The signal receiving end of the billing module is connected to the antenna 142; the antenna 142 is placed on the upper surface of the rear shell 140 to facilitate the reception of external wireless signals. The power output terminal of the billing module is connected to the power input terminal of the control module; the control output terminal of the control module is connected to the motor; the start trigger terminal of the control module is connected to the start button 132; the position detection port of the control module is respectively connected to the output terminals of the initial travel switch 131 and the end travel switch 141, and the end travel switch 141 is located on the side of the rear shell 140 facing the installation platform 160, and is used to detect the end position of the installation platform 160. A QR code recording the unique identity information of the mobile component is affixed to the rear shell 140.

[0159] The control module is used to control the running speed, running time and running direction of the motor, and these conditions can be set in the control module. The rotating shaft of the motor cooperates with the belt driving pulley, and the transmission speed, time and direction of the belt 170 are controlled by the motor, thereby controlling the speed, time and direction of the installation platform 160 on the track, so as to achieve different physical therapy methods for different objects, different parts and different symptoms, making the physical therapy effect more targeted. Specifically, when the rotating shaft of the control motor is rotated in one direction, the belt 170 can be controlled to move the installation platform 160 in a direction close to the front shell 130; when the rotating shaft of the control motor is rotated in the other direction, the belt 170 can be controlled to move the installation platform 160 in a direction away from the front shell 130.

[0160] Before starting, the mounting platform 160 is located at the initial position, and the front end surface of the protective shell 150 contacts the moving contact of the initial travel switch 131 .

[0161] During startup, the user scans the corresponding QR code with a mobile phone and pays the corresponding fee. The remote control terminal then issues a startup instruction. After the billing module receives the startup instruction through antenna 142, it turns on the power and issues a voice reminder to notify the user that the therapy is ready.

[0162] After the user adjusts the position, he presses the start button 132. After receiving the signal sent by the start button 132, the start trigger end of the control module controls the motor to run, driving the installation platform 160 to move away from the user.

[0163] When the tail of the installation platform 160 touches the moving contact of the end travel switch 141, the position detection port of the control module receives the signal of the end travel switch 141 and controls the motor to stop running; after stopping for more than or equal to 5 seconds, the control module controls the motor to run in reverse, allowing the installation platform 160 to move to the initial position.

[0164] When the front end of protective shell 150 touches the moving contact of initial travel switch 131, and the position detection port of the control module receives a signal from end travel switch 141, the control motor stops, and mounting platform 160 is reset. The billing module disconnects the power supply to the control module after a preset time. At this time, pressing the start button 132 is ineffective, and the user needs to scan the code again to pay before restarting.

[0165] The counter is coupled to the end travel switch 141. When the moving contact of the end travel switch 141 is closed, the value of the counter is increased by 1. With the counter, it is convenient for local management personnel to intuitively count the number of times the cold-dispelling device 10 is used.

[0166] The essential oil bottle 210 containing essential oil can be directly placed on the mounting platform 160, and the bottle cap of the essential oil bottle 210 can be opened when in use; or for convenience, the essential oil bottle 210 can be designed as an automated structure that can automatically open and close the cap.

[0167] It should be noted that in the mobile assembly 100 of the embodiment of the present application, the front housing 130 may not have a counter, and the initial travel switch 131 may be replaced with other infrared sensors, acoustic sensors, or other structures to detect the position of the mounting platform 160, while the start button 132 may be located in the rear housing 140 or elsewhere. In addition, other functional modules may be added to the front housing 130 as needed. As for the rear housing 140, the billing module 143 and antenna 142 may also be omitted, the end travel switch 141 may be replaced with other infrared sensors, acoustic sensors, or other structures to detect the position of the mounting platform 160, and the control module, motor, and power supply may be located in the front housing 130 or elsewhere. In addition, other functional modules may also be added to the rear housing 140 as needed to meet the various usage requirements of customers, and no further limitations are given.

[0168] By adopting the technical solution of the embodiment of the present application, the cold-dispelling device 10 does not occupy floor space and is relatively lightweight. Through track positioning, the movement trajectory of the energy source 200 and the nested diversion assembly 300 can be precisely defined, eliminating the risk of interference with other objects. After resetting, no manual adjustment is required, making it easy to use.

[0169] Correspondingly, as shown in FIG23 , the embodiment of the present application further discloses a method for using the above-mentioned cold-removing device, which specifically includes the following steps:

[0170] S1: aligning one end of the nested guide assembly with the user to be cleared of cold air, and aligning the other end with the essential oil bottle on the cold-clearing device, with the distance between the nested guide assembly and the user to be cleared of cold air being a first preset alignment distance, and with the distance between the nested guide assembly and the essential oil bottle being a second preset alignment distance;

[0171] S2: After waiting for a first preset time, the essential oil bottle is opened, and at the same time, the control module drives the slide rail to drive the essential oil bottle and the nested guide assembly to move a first preset distance away from the user to be de-cold-expelled;

[0172] S3: the slide rail drives the essential oil bottle and the nested guide assembly to move a first preset distance in a direction away from the user to be cleared of cold air, and then stays for a second preset time;

[0173] S4: closing the bottle cap of the essential oil bottle containing the essential oil;

[0174] S5: Control the slide rail to drive the essential oil bottle and the nested guide assembly back to the initial position.

[0175] Among them, in actual use, if you choose an essential oil bottle without a cover, the operation of "opening the essential oil bottle" in step S2 can be omitted; if you choose an essential oil bottle without its own push rod motor that cannot control the opening and closing of the bottle cap, then step S4 can be omitted, and the essential oil bottle can be manually closed after the physical treatment; if during the physical treatment process, the user is in a hurry or the essential oil is insufficient, step S3 can be omitted. Therefore, in actual operation, based on the use method of the above-mentioned cold-dispelling equipment, you can selectively use or adjust the above-mentioned steps according to your own actual conditions, which are all in line with the use specifications of the above-mentioned cold-dispelling equipment and will not hinder the use effect of the cold-dispelling equipment. Therefore, they all fall within the scope of protection of this application.

[0176] The inventors discovered that to establish a stable connection between essential oils and the cold, the distances between the essential oil and the user, between the nested guide assembly and the user, and between the nested guide assembly and the essential oil must be within appropriate ranges. If the distances are too short, the body's cold energy and yang energy will tend to repel each other, making it difficult to establish a stable connection. If the distances are too long, the connection between the essential oil and the user's cold energy will be weak.

[0177] By allowing the essential oil to remain for a first preset time before moving it, a stable connection between the essential oil and the cold air can be established, thereby preventing the connection from being disconnected during subsequent movement.

[0178] For the first preset distance, as long as the essential oil maintains a continuous connection with the body's chill, the longer the distance, the better the effect of drawing out the chill. However, as the distance increases, the connection between the essential oil and the body's chill weakens. Once this connection is broken, the chill is no longer drawn out, and the effect is actually reduced. Therefore, it is necessary to control the first preset distance to avoid a break in the connection between the essential oil and the chill.

[0179] After the essential oil finishes moving, the cold air can continue to be drawn out by continuing its previous inertia and continue to stay for the second preset time, which can further enhance the therapeutic effect. However, the stay time cannot be too long, otherwise the cold air and the essential oil will enter a state of equilibrium, and the trend of drawing out the cold air will not be obvious.

[0180] The essential oil can maintain a uniform speed while moving the first preset distance away from the user to be freed of cold, which is conducive to stabilizing the connection between the essential oil and the cold.

[0181] Specifically, in step S1, the first preset alignment distance (the distance between the nested diversion assembly and the user to be dispelled cold) is controlled not to exceed 30 cm, and the second preset alignment distance (the distance between the nested diversion assembly and the energy source) is also not to exceed 30 cm. In step S2, the first preset time is greater than or equal to 5s, and the control module drives the moving assembly to drive the energy source and the nested diversion assembly to move a distance of no more than 2m at a speed not exceeding 20mm / s, that is, the first preset distance is less than 2m. In step S3, after the moving assembly drives the energy source and the nested diversion assembly to move the first preset distance in the direction away from the user to be dispelled cold, the residence time is greater than or equal to 5s, that is, the second preset time is greater than or equal to 5s.

[0182] Moreover, as needed, the nested guide assembly in the embodiment of the present application can be replaced with a guide device, which only requires increasing the number of guide brackets and adjusting the distance between the structures.

[0183] For the nested diversion components, diverters and cold-removing equipment of the above-mentioned embodiments, the applicant recruited a number of volunteers to conduct experiments. Three cases are selected below to illustrate the therapeutic effects of the technical solution of this application.

[0184] Case 1: An elderly male patient presented with the following complaints: recurrent left knee pain with limited mobility for over 5 years. Five years ago, the patient developed left knee pain with limited mobility without any apparent cause. The pain was persistent, dull, and did not radiate to other areas. The pain was often triggered by fatigue or cold, and the patient was not taken seriously or received regular treatment at the time. Symptoms: The patient had pain in the left knee, with mild limitation of flexion and extension, which did not affect walking. He had slight discomfort when going up and down stairs, and slight joint stiffness in the morning, which improved with activity. His bowel movements were normal. Physical examination: There was no obvious redness, swelling, or sinus tract on the skin of the left knee joint. There was local tenderness (+) on the left knee joint, and the local skin temperature was decreased. The left knee grinding test (+), floating patella test (-), anterior and posterior drawer test (-), and lateral stress test (-) showed no abnormalities in the circumference of the thighs and calves on both sides. The WOMAC score was 66 (see Table 1). Traditional Chinese Medicine diagnosis: Bi syndrome (cold bi). Western Medicine diagnosis: left knee osteoarthritis.

[0185] Treatment method: Use the curvature gradient double-horn guide piece described in the previous case (PCT / CN2023 / 091852) combined with essential oil as a physical therapy device, three times a week, and a course of four weeks.

[0186] The specific treatment method is as follows: apply a guiding agent, such as alcohol, to the area to be de-cold-removed; align the large end of the curvature gradient double-flared guide with the area to be de-cold-removed, and the other large end of the curvature gradient double-flared guide with the essential oil, with the distance between the curvature gradient double-flared guide and the area to be de-cold-removed being 15 cm, and the distance between the curvature gradient double-flared guide and the essential oil being 15 cm. After a 10-second pause, the control module begins controlling the moving assembly to move the essential oil and the curvature gradient double-flared guide at a speed of 4 mm / s and a distance of 100 cm.

[0204] Case 3: An elderly woman presented with recurrent left knee pain and limited mobility for over eight years. She had long worked in paddy fields. Eight years ago, she developed left knee pain and limited mobility without apparent cause. The pain was persistent, felt while standing and walking, and limited knee mobility, making squatting impossible. She also experienced severe chills and had to wear long pants even in the summer. She had intermittent treatments with warm acupuncture, moxibustion, and massage, but the symptoms recurred. Current symptoms: Left knee pain with limited mobility, morning stiffness, which improved slightly with activity, but worsened in rainy weather. Squatting was difficult, and walking and climbing stairs were affected. Physical examination revealed no significant redness, swelling, or sinus tract in the left knee joint.

Bilateral calf circumference was normal, and the WOMAC score was 140 (see Table 7). Traditional Chinese Medicine diagnosis: Bi syndrome (cold arthritis). Western medicine diagnosis: left knee osteoarthritis.

[0205] Treatment method: Use a two-stage double-nested diversion component combined with essential oils as a physical therapy device, three times a week, and a course of four weeks.

[0206] The specific treatment method is as follows: apply a guiding agent, such as alcohol, to the area to be cleared of cold; align the large end of the two-stage double-nested diversion assembly with the area to be cleared of cold, and align the other large end of the two-stage double-nested diversion assembly with the essential oil, with the distance between the two-stage double-nested diversion assembly and the area to be cleared of cold being 15 cm, and the distance between the two-stage double-nested diversion assembly and the essential oil being 15 cm. After a 10-second pause, the control module begins to control the moving assembly to move the essential oil and the two-stage double-nested diversion assembly, with a moving speed of 4 mm / s and a moving distance of 100 cm. After reaching the designated position, it pauses for 15 seconds and controls the moving assembly to drive the essential oil back to its initial position.

[0207] After six sessions of physical therapy, the patient's pain was significantly reduced, her range of motion improved, her knee coldness improved significantly, and she could climb stairs with ease. Physical examination revealed no significant redness, swelling, or sinus tract in the left knee joint. Local tenderness (+) was noted in the left knee joint, and the local skin temperature was decreased. The left knee joint grinding test (+), floating patellar test (+), anterior and posterior drawer test (-), and lateral stress test (-) were positive.

[0211] Table 7 WOMAC score of case 3 before physical therapy

[0212] Table 8 WOMAC score of case 3 after 6 sessions of physical therapy

[0213] Table 9 WOMAC score of case 3 after 12 sessions of physical therapy

[0214] Note: In the three cases described above, each question was evaluated using a VAS scale, with 0 representing normal and 10 representing the most severe. The total score is the sum of the scores for the 24 components, with higher WOMAC scores indicating more severe OA. Based on the total score, the severity of OA was assessed according to the following criteria: mild <80, moderate 80-120, and severe >120.

[0215] By comparing the three cases, we can find that:

[0216] 1) The WOMAC score of the patient in Case 1 before physical therapy was 66 points, the WOMAC score of the patient in Case 2 before physical therapy was 95 points, and the WOMAC score of the patient in Case 3 before physical therapy was 140 points. Yes, from Case 1 to Case 3, the severity of the patient's physical discomfort before physical therapy increased in sequence;

[0217] 2) The patient in Case 1 did not receive any other treatment before physical therapy; the patient in Case 2 used self-heating and massage before physical therapy; the patient in Case 3 used acupuncture, moxibustion, massage and other treatments before physical therapy;

[0218] 3) The patient in Case 1 had a mild relapse three months after the completion of physical therapy, while the patients in Cases 2 and 3 had no relapse within three months after the completion of physical therapy;

[0219] 4) In case 1, the WOMAC score of the patient decreased by 10 points after 6 physical therapy sessions, and decreased by 26 points after 12 physical therapy sessions. In case 2, the WOMAC score of the patient decreased by 28 points after 6 physical therapy sessions, and decreased by 36 points after 12 physical therapy sessions. In case 3, the WOMAC score of the patient decreased by 40 points after 6 physical therapy sessions, and decreased by 48 points after 12 physical therapy sessions.

[0220] It can be seen that in Cases 1, 2, and 3, the reduction in WOMAC score after 12 physical treatments compared with 6 physical treatments was greater than the reduction in WOMAC score after 6 physical treatments compared with before physical treatment. In other words, the difference in WOMAC score increased with each stage of physical treatment. Therefore, whether using a double-flared guide with a gradually changing curvature combined with essential oil as a physical therapy device, using a two-stage single-nested guide assembly combined with essential oil as a physical therapy device, or using a two-stage double-nested guide assembly combined with essential oil as a physical therapy device, all have positive effects on physical therapy, and the longer the use, the better the effect.

[0221] However, since the WOMAC score of the patient in Case 1 decreased by 10 points after 6 physical therapy sessions compared with the WOMAC score before physical therapy, the WOMAC score of the patient in Case 2 decreased by 28 points after 6 physical therapy sessions compared with the WOMAC score before physical therapy, and the WOMAC score of the patient in Case 3 decreased by 40 points after 6 physical therapy sessions compared with the WOMAC score before physical therapy; and, the WOMAC score of the patient in Case 1 decreased by 26 points after 12 physical therapy sessions compared with the WOMAC score after 6 physical therapy sessions, the WOMAC score of the patient in Case 2 decreased by 36 points after 12 physical therapy sessions compared with the WOMAC score after 6 physical therapy sessions, and the WOMAC score of the patient in Case 3 decreased by 48 points after 12 physical therapy sessions compared with the WOMAC score after 6 physical therapy sessions. It can be found that the therapeutic effect of using a two-stage double-nested diversion assembly combined with essential oil as a physical therapy device is better than the therapeutic effect of using a two-stage single-nested diversion assembly combined with essential oil as a physical therapy device, and the therapeutic effect of using a two-stage single-nested diversion assembly combined with essential oil as a physical therapy device is better than the therapeutic effect of using a curvature gradient double-flared diversion piece combined with essential oil as a physical therapy device. It can further be found that the diversion effect of the two-stage double-nested diversion assembly is better than the diversion effect of the two-stage single-nested diversion assembly, and the diversion effect of the two-stage single-nested diversion assembly is better than the diversion effect of the curvature gradient double-flared diversion piece.

[0222] Moreover, after the treatment plan of the double-flared guide component with gradually changing curvature was adopted in Case 1, the patient had a mild recurrence three months after the treatment; while after the treatment plan of the nested guide component was adopted in Cases 2 and 3, the patients did not have a recurrence after one month or three months, indicating that the nested wormhole is more thorough in eradicating the disease than the non-nested one, and the treatment effect is better, and the effect is more stable and will not relapse.
