[0001] This application relates to the field of moxibustion equipment, and in particular to a moxibustion device. Background Technology

[0002] Moxibustion is a therapy that uses moxa (such as moxa sticks, moxa wool, or moxa cones) in conjunction with a moxibustion device. Specifically, the lit moxa is placed inside the moxibustion device, and the smoke or heat generated by the burning moxa is provided to the body through the device, thereby providing moxibustion treatment to joints or acupoints.

[0003] In existing moxibustion devices, the lifting slider is usually directly snapped into the housing during product assembly. This results in a high rate of damage to the side protrusions on the lifting slider and also affects the strength of the side protrusions in the assembled product. Summary of the Invention

[0017] According to some technical solutions of this application, the guide structure includes limiting ribs, wherein the second shell is nested outside the first shell, and a plurality of limiting ribs are raised on the inner wall surface of the second shell, wherein one or more of the limiting ribs extend along the lifting direction of the lifting slider, and one end of the limiting rib along the extending direction corresponds to the position of the first cover, and the limiting rib abuts against the first cover to axially limit the first shell and the second shell; wherein two or more of the limiting ribs are arranged at intervals, and a guide groove is formed between adjacent limiting ribs to accommodate the side protrusion and allow the side protrusion to slide, and the two groove walls of the guide groove abut against the side protrusion to restrict the rotation of the lifting slider.

[0018] According to some technical solutions of this application, the second shell is provided with a first opening, and one end of the first shell away from the first cover passes through the first opening and extends to the outside of the second shell. The extended end of the first shell is provided with a base, and the base can abut against the second shell. The movement of the first shell along the extension direction of the first opening is limited by the abutting of the base against the second shell, and the movement of the first shell along the extension direction of the first opening is limited by the abutting of the first cover against the second shell.

[0019] According to some technical solutions of this application, the base forms a moxibustion opening, the space enclosed by the first shell is connected to the moxibustion opening, and a plurality of first ventilation holes are provided around the moxibustion opening on the base. The plurality of first ventilation holes are arranged at circumferential intervals, and the first ventilation holes are arranged vertically or inclined downwards. The space enclosed by the first shell is connected to the environment through the first ventilation holes. A gap is defined between the first shell and the second shell. The first shell is provided with a second ventilation hole, and the space enclosed by the first shell is connected to the gap through the second ventilation hole. A second opening is provided at the end of the second shell away from the base. Based on the axial limitation between the first shell and the second shell by the first cover abutting against each other, the moxibustion device also includes a second cover. The second cover is connected to the second shell and seals the second opening. The first cover and part of the first shell are located in the space enclosed by the second shell and the second cover. A third ventilation hole is provided on the second cover, and the space enclosed by the first shell is connected to the environment through the third ventilation hole.

[0020] According to some technical solutions of this application, the moxibustion device further includes: a connecting seat connected to the base, the connecting seat being disposed at the moxibustion port, the connecting seat having a through channel, the channel having an outlet end, the outlet end being lower than the communication position between the space enclosed by the first shell and the first ventilation hole; and a dust collection net connected to the connecting seat and covering the channel.

[0021] According to some technical solutions of this application, the threaded groove is defined with a first end and a second end along the extension direction, wherein the distance between the threaded groove and the end of the first shell gradually decreases from the first end to the second end; the communication position between the threaded groove and the assembly groove is at a certain distance from the first end, and the straight distance between the communication position and the opening is less than the straight distance between the first end of the threaded groove and the end of the first shell.

[0022] In this application, a mounting groove and a threaded groove are provided on the first shell, and the mounting groove extends to the end of the first shell, forming an opening at the end of the first shell. Thus, when assembling the lifting slider with the first shell, during the process of nesting the lifting slider inside the first shell, the side protrusion can enter the mounting groove along the opening and pass through the mounting groove into the threaded groove. This way, during the assembly process of the lifting slider and the first shell, the side protrusion is avoided, making the assembly of the lifting slider and the first shell more effortless and convenient. Furthermore, the side protrusion experiences less obstruction during the insertion into the threaded groove, which can greatly reduce the resistance to jamming. This design reduces assembly damage to the lateral protrusions, improves product yield, and lowers the risk of breakage of the lateral protrusions in the moxibustion device, thus enhancing product quality. Simultaneously, the moxibustion device incorporates a retaining edge within the assembly groove. This retaining edge supports the assembly groove, reinforcing and shaping the first shell. This reduces the probability of deformation in the threaded groove, ensuring smoother sliding of the lateral protrusion within the groove and minimizing jamming. It allows users to easily adjust the distance between the skin and the moxa stick by moving the lifting slider to regulate the moxibustion temperature, making operation easier and smoother. In this way, a simple structure comprehensively improves the ease of assembly of the lifting slider, reduces assembly damage to the lateral protrusions of the lifting slider, and effectively ensures smooth sliding between the assembled lateral protrusion and the threaded groove.

Detailed Implementation

[0037] Although this application can be readily embodied in various forms of implementation, only some specific embodiments are shown in the accompanying drawings and will be described in detail in this specification. It is understood that this specification should be regarded as an exemplary illustration of the principles of this application and is not intended to limit the application to what is described herein.

[0038] Therefore, a feature described in this specification is used to illustrate one feature of one embodiment of this application, and does not imply that every embodiment of this application must have the described feature. Furthermore, it should be noted that this specification describes many features. While certain features may be combined to illustrate possible system designs, these features may also be used in other combinations not explicitly stated. Therefore, unless otherwise stated, the described combinations are not intended to be limiting.

[0039] In the embodiments shown in the accompanying drawings, the directional indications (such as up, down, etc.) used to explain the structure and movement of the various elements of this application are relative rather than absolute. These descriptions are appropriate when these elements are in the positions shown in the drawings. If the description of the positions of these elements changes, these directional indications also change accordingly.

[0040] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the examples set forth herein; rather, they are provided to make the description of this application more comprehensive and complete, and to fully convey the concept of the exemplary embodiments to those skilled in the art. The drawings are merely illustrative of this application and are not necessarily drawn to scale. The same reference numerals in the drawings denote the same or similar parts, and therefore repeated descriptions of them will be omitted.

[0041] The preferred embodiments of this application will be further described in detail below with reference to the accompanying drawings.

[0042] One embodiment of this application provides a moxibustion device 10, which can be used to carry moxa (such as moxa sticks, moxa cones, moxa wool, etc.) and to be used together with the carried moxa for moxibustion therapy.

[0043] like Figure 1 As shown, the moxibustion device 10 includes a moxibustion cup 100 and a moxibustion tool 200. The moxibustion tool 200 is used to mount moxa materials (such as moxa sticks, moxa cones, moxa wool, etc.). A lifting slider 130 is defined within the moxibustion cup 100. The lifting slider 130 is detachably connected to the moxibustion tool 200, allowing the moxibustion tool 200 to be detachably mounted on the lifting slider 130. The lifting slider 130 can move up and down within the moxibustion cup 100. This movement causes the moxibustion tool 200 and the moxa materials mounted on the lifting slider 130 to move up and down together. This changes the distance between the moxa materials on the lifting slider 130 and the surface of the skin being treated, thereby adjusting the perceived temperature of the skin surface by controlling this distance change, avoiding excessive cold or heat, and improving the moxibustion experience.

[0044] For example, such as Figure 1and Figure 7 As shown, the moxibustion cup 100 includes a first shell 120 and a lifting slider 130. Figure 1 As shown, the first housing 120 is provided with a threaded groove 1201. The lifting slider 130 is provided with a side protrusion 131. (As shown...) Figure 7 As shown, the lifting slider 130 is nested in the first shell 120, and the side protrusion 131 passes through the threaded groove 1201 and can slide along the threaded groove 1201. The lifting slider 130 is raised or lowered by sliding the side protrusion 131 along the threaded groove 1201.

[0045] Furthermore, combined Figure 1 and Figure 2 It is understood that the first shell 120 is also provided with an assembly groove 1203, which communicates with the threaded groove 1201. The assembly groove 1203 extends to the end 1207 of the first shell 120 to define the opening 12031 of the assembly groove 1203. One or more retaining edges are provided in the assembly groove 1203 (the retaining edges can be specifically referred to in the appendix). Figure 5 (The first protruding edge 12035 and / or the second protruding edge 12036 and / or the protruding rib 151 shown are understood.) Thus, when assembling the lifting slider 130 with the first housing 120, during the process of nesting the lifting slider 130 within the first housing 120, the side protrusion 131 can enter the assembly groove 1203 along the opening 12031 of the assembly groove 1203, and pass through the assembly groove 1203 into the threaded groove 1201. In this way, during the assembly process of the lifting slider 130 and the first housing 120, the side protrusion 131 is avoided, making the assembly between the lifting slider 130 and the first housing 120 more effortless and convenient. Furthermore, the side protrusion 131 experiences less obstruction during insertion into the threaded groove 1201, which can greatly reduce assembly damage to the side protrusion 131, improve the product yield, and reduce the risk of breakage of the side protrusion 131 in the moxibustion cup 100, thereby improving product quality. Meanwhile, the moxibustion cup 100 has a retaining edge within the assembly groove 1203. This retaining edge supports the assembly groove 1203, reinforcing and shaping the first shell 120. This reduces the probability of deformation of the threaded groove 1201. For example, it restricts deformation of the assembly groove 1203 along the closing direction of the opening 12031, thus reducing the probability of deformation. This ensures smoother sliding of the side protrusion 131 within the threaded groove 1201, reducing the problem of the side protrusion 131 getting stuck. This allows the user to adjust the moxibustion temperature by changing the distance between the skin and the moxa stick through the lifting and lowering movement of the lifting slider 130, making operation easier and smoother. Thus, with a simple structure, this design comprehensively improves the ease of assembly of the lifting slider 130, reduces assembly damage to the side protrusion 131 of the lifting slider 130, and effectively ensures smooth sliding between the assembled side protrusion 131 and the threaded groove 1201.

[0046] In some embodiments, such as Figure 2 As shown, the retaining edge includes a convex edge (the convex edge can be specifically understood by referring to the first convex edge 12035 and the second convex edge 12036 shown in the attached drawings). A portion of the inner wall surface of the assembly groove 1203 is raised to form the convex edge. On one hand, the convex edge can act as a reinforcing rib to strengthen the first shell 120; on the other hand, the convex edge can support the assembly groove 1203 within the assembly groove 1203, strengthening and shaping it. This prevents the first shell 120 from deforming due to its weak strength, thus avoiding jamming during the movement of the lifting slider 130 (such as lifting movement). Furthermore, while reducing the risk of deformation of the threaded groove 1201, during the assembly process of the lifting slider 130 and the first shell 120, the convex edge on the inner wall surface of the assembly groove 1203 and the side protrusion 131 can be elastically engaged, thus not affecting assembly convenience and preventing damage to the side protrusion 131. This structure also has the advantages of simple structure, convenient processing, and low cost.

[0047] Further optional, such as Figure 2 As shown, the end of the assembly groove 1203 away from the opening 12031 defines a communication port 12032, and the position of the protruding edge within the assembly groove 1203 is closer to the communication port 12032 than that within the opening 12031. Specifically... Figure 2 As shown, the protruding edge is located on the side of the assembly groove 1203 near the connecting port 12032. This provides a better shaping effect for the threaded groove 1201.

[0048] In some specific embodiments, such as Figure 2 As shown, the assembly groove 1203 includes a first side wall 12033 and a second side wall 12034. A first protruding edge 12035 is provided on the first side wall 12033, and a second protruding edge 12036 is provided on the second side wall 12034. The first side wall 12033 and the second side wall 12034 are arranged opposite to each other, and the positions of the first protruding edge 12035 and the second protruding edge 12036 are corresponding. In this way, the first protruding edge 12035 and the second protruding edge 12036 can abut against each other to support and shape the assembly groove 1203. At the same time, the protrusion height of the first protruding edge 12035 and the second protruding edge 12036 relative to the inner wall of the assembly groove 1203 does not need to be too high. This makes it easier to ensure the forming quality of the first protruding edge 12035 and the second protruding edge 12036, and reduce the risk of breakage of the first protruding edge 12035 and the second protruding edge 12036. It also reduces the processing and forming difficulty of the first shell 120, which helps to reduce product costs.

[0049] Further optional, such as Figure 2As shown, a guide slope 12037 is provided on one or more of the first protruding edge 12035 and the second protruding edge 12036 (of course, the guide slope 12037 can also be replaced by a guide arc surface). In this way, the snap-fit ​​damage between the side protrusion 131 and the first protruding edge 12035 / second protruding edge 12036 can be further reduced, and the ease of assembly can be improved.

[0050] Optionally, such as Figure 2 As shown, guide slopes 12037 are provided on opposite sides of the first protruding edge 12035, and / or guide slopes 12037 are provided on opposite sides of the second protruding edge 12036. In this way, the elastic engagement effect between the side protrusion 131 and the first protruding edge 12035 and / or the second protruding edge 12036 is better, and it is also convenient to install and remove the side protrusion 131.

[0051] In some embodiments, the retaining edge includes a rib 151. Specifically, in conjunction with... Figure 1 and Figure 4 It is understood that the moxibustion cup 100 also includes a first cover 150, which is connected to one end of the first shell 120. The first cover 150 is provided with a protruding rib 151, which extends into the assembly groove 1203. The protruding rib 151 can support the assembly groove 1203 within the assembly groove 1203, thereby strengthening and shaping the first shell 120. This can correspondingly reduce the probability of deformation of the threaded groove 1201, ensuring smoother sliding of the side protrusion 131 within the threaded groove 1201 and reducing the risk of jamming of the side protrusion 131 within the threaded groove 1201. In this way, a simple structure comprehensively achieves the effects of improving the ease of assembly of the lifting slider 130, reducing assembly damage to the side protrusion 131 of the lifting slider 130, and effectively ensuring the smooth sliding between the assembled side protrusion 131 and the threaded groove 1201.

[0052] In some embodiments, such as Figure 3 As shown, the first cover 150 forms a mating opening 155, and a stepped portion 154 is defined within the mating opening 155. A rib 151 protrudes from the stepped portion 154. The mating opening 155 is then combined with... Figure 4 and Figure 5It is understood that a portion of the first shell 120 is nested within the mating opening 155. The end 1207 of the first shell 120 and the opening 12031 of the mounting groove 1203 correspond to the position of the stepped portion 154. The protruding rib 151 on the stepped portion 154 corresponds to the position of the opening 12031 and extends into the mounting groove 1203 along the opening 12031. In this way, the mating opening 155 can restrict the deformation of the mounting groove 1203 in the direction of opening 12031, and the protruding rib 151 can restrict the deformation of the mounting groove 1203 in the direction of closing 12031. Thus, the first shell 120 is effectively strengthened and shaped, the deformation probability of the threaded groove 1201 is correspondingly reduced, and the smoothness of sliding between the side protrusion 131 and the threaded groove 1201 is better guaranteed.

[0053] In one specific embodiment, such as Figure 7 As shown, the moxibustion cup 100 includes a first cover 150, a first shell 120, and a lifting slider 130. The lifting slider 130 is nested inside the first shell 120. The first shell 120 is provided with a threaded groove 1201 and an assembly groove 1203 with an opening 12031. The assembly groove 1203 communicates with the threaded groove 1201, and multiple baffles are provided in the assembly groove 1203.

[0054] like Figure 3 As shown, the threaded groove 1201 is configured in a helical shape, and in the art, the threaded groove 1201 may also be referred to as a helical groove. The threaded groove 1201 defines a first end and a second end along its extension direction, wherein the distance between the threaded groove 1201 and the end 1207 of the first housing 120 gradually decreases from the first end to the second end. The communication position between the threaded groove 1201 and the assembly groove 1203 (the communication position, i.e., the communication opening 12032) is spaced from the first end of the threaded groove 1201, and the straight-line distance between the communication position and the opening 12031 is less than the straight-line distance between the first end of the threaded groove 1201 and the end 1207 of the first housing 120. In this way, the strength reduction caused by the opening of the assembly groove 1203 on the first shell 120 is relatively small, and the support and shaping effect of the edge (such as the protruding edge and / or the protruding rib 151) on the assembly groove 1203 is also better. As a result, the deformation probability of the threaded groove 1201 is lower, the smoothness of the sliding of the side protrusion 131 along the threaded groove 1201 is better, and the elasticity of the two side walls of the assembly groove 1203 is also better. As a result, the assembly stress between the protruding edge and the side protrusion 131 on the two side walls of the assembly groove 1203 is smaller, and the side protrusion 131 is less damaged.

[0055] Furthermore, combined Figure 4 and Figure 5It is understood that some of the retaining edges within the assembly groove 1203 are raised ribs 151, and the raised ribs 151 are disposed on the first cover 150. Other retaining edges within the assembly groove 1203 are raised edges, and the raised edges are disposed on the inner wall surface of the assembly groove 1203. The first cover 150 is located at one end of the first shell 120. The raised ribs 151 extend into the assembly groove 1203 along the opening 12031. Raised edges (specifically, for example, the first raised edge 12035 and / or the second raised edge 12036) are raised on the inner wall surface of the assembly groove 1203 at the position between the raised ribs 151 and the threaded groove 1201. In this way, the assembly groove 1203 is evenly supported in the area between the opening 12031 and the connecting opening 12032, resulting in better reinforcement and shaping of the assembly groove 1203. Correspondingly, the deformation probability of the threaded groove 1201 is lower, and the smoothness of the sliding of the side protrusion 131 along the threaded groove 1201 is better guaranteed.

[0056] In some embodiments, an insert 1206 is provided on one of the stepped portion 154 and the end portion 1207 of the first housing 120, and an insertion port 153 is provided on the other, with the insert 1206 inserted into the insertion port 153.

[0057] To give a further example, such as Figure 3 As shown, the first shell 120 is provided with two or more threaded grooves 1201, and the first shell 120 is provided with an assembly groove 1203 corresponding to each threaded groove 1201. Two or more openings 12031 are distributed at the ends 1207 of the first shell 120, and the openings 12031 are spaced apart, so that the ends 1207 of the first shell 120 are divided into a multi-segment structure by the openings 12031. Each segment end 1207 of the first shell 120 is provided with at least one insert 1206 or socket 153. In this way, on the one hand, by using the insertion slot 153 and the insertion strip 1206 to cooperate, it is easy to assemble and position the protruding rib 151 and the opening 12031. On the other hand, the cooperation between the insertion strip 1206 and the insertion slot 153 can limit the opening and closing deformation of the assembly groove 1203, further improving the shaping reliability and accuracy of the assembly groove 1203. As a result, the shape retention effect and restoration of the threaded groove 1201 are better, and the cooperation between the lifting slider 130 and the threaded groove 1201 is smoother and more precise, which can realize a more refined adjustment of the skin temperature.

[0058] In some embodiments, such as Figure 4 As shown, the first shell 120 and the first cover 150 are snapped together. In this way, the first shell 120 and the first cover 150 are easy to install and remove, and the connection between the first shell 120 and the first cover 150 is reliable. The protruding rib 151 is not easily pushed out of the assembly groove 1203, which can achieve more reliable reinforcement and shaping of the assembly groove 1203.

[0059] Further optional, such as Figure 3 As shown, a protruding buckle 152 is provided on the inner surface of the side wall of the mating opening 155, and an insertion opening 153 is provided on the stepped portion 154. The insertion opening 153 on the stepped portion 154 is a through structure and corresponds to the position of the protruding buckle 152. A slot 1205 is provided on the side wall of the first shell 120, and an insert 1206 is provided at the end 1207 of the first shell 120 corresponding to the position of the slot 1205. In this way, the insertion opening 153 can also serve as the ejection groove for the protruding buckle 152, thereby eliminating the need for a separate ejection groove. The structure of the first cover 150 is simplified, the production cost is lower, and the engagement state of the insert 1206 and the through insertion opening 153 makes it easier to identify whether the protruding buckle 152 and the slot 1205 are properly assembled, and whether the rib 151 and the opening 12031 are properly assembled. The assembly between the first cover 150 and the first shell 120 has a good anti-misfit effect.

[0060] Alternatively, the insert 1206 may be provided with a guide bevel or a guide arc surface that can adapt to the buckle 152. In this way, the assembly stress between the buckle 152 and the insert 1206 is reduced, which can reduce assembly damage and improve the product yield.

[0061] In some embodiments, such as Figure 7 As shown, the moxibustion cup 100 also includes a second shell 110, which is disposed outside the first shell 120 (of course, in other embodiments, the second shell 110 may also be nested inside the first shell 120). The first shell 120 and the second shell 110 can rotate relative to each other. The second shell 110 is provided with a guide structure for limiting the rotation of the lifting slider 130 (the guide structure can be understood by referring to the limiting rib 111 shown in the attached figure). When the first shell 120 and the second shell 110 rotate relative to each other, the lifting slider 130 is driven to rise or fall. In this way, the relative rotation of the lifting slider 130 relative to the second shell 110 along both sides of the circumference is limited. Thus, driving the relative rotation between the first shell 120 and the second shell 110 can precisely and efficiently drive the lifting slider 130 to rise or fall, thereby adjusting the perceived temperature of the skin surface to be moxibusted. The operation is simple and convenient, and the temperature adjustment is more precise and efficient.

[0062] Furthermore, such as Figure 7 As shown, the first cover 150 and the second shell 110 can abut against each other, and the abutment of the first cover 150 and the second shell 110 axially limits the distance between the first shell 120 and the second shell 110. In this way, in addition to providing the rib 151 to strengthen and shape the assembly groove 1203, the first cover 150 also acts as a limiting member to axially limit the distance between the first shell 120 and the second shell 110, thereby simplifying the number of product parts and facilitating the assembly of the product.

[0063] To give a further example, such as Figure 7 As shown, the guide structure includes limiting ribs 111. Multiple limiting ribs 111 are protruding from the inner wall of the second shell 110, with two or more ribs 111 arranged at intervals. A guide groove is formed between adjacent limiting ribs 111 to accommodate and allow the side protrusion 131 to slide. The two walls of the guide groove abut against the side protrusion 131 to restrict the rotation of the lifting slider 130. Furthermore, one or more limiting ribs 111 extend along the lifting direction of the lifting slider 130, and one end of the limiting rib 111 along the extending direction corresponds to the position of the first cover 150. The limiting rib 111 abuts against the first cover 150, axially limiting the distance between the first shell 120 and the second shell 110.

[0064] Optionally, the limiting rib 111 on the inner wall surface of the second shell 110 that defines the guide groove and the limiting rib 111 that abuts against and limits the first cover 150 can be the same limiting rib 111 or different limiting ribs 111.

[0065] In this design, a limiting rib 111 is used to limit the guide groove to restrict the rotation of the lifting slider 130, and the limiting rib 111 is used to abut and limit the first cover 150150. In this way, the structure of the second shell 110 is simplified, which facilitates the processing and production of the second shell 110 and also helps to reduce the cost of the second shell 110.

[0066] Optionally, the side protrusion 131 may be, for example, a protruding post with an arc-shaped side. This reduces the friction between the protruding post and the limiting rib 111 and the threaded groove 1201, making it easier to adjust the lifting position of the lifting slider 130. Preferably, the lifting slider 130 has two protruding posts, such as... Figure 6 As shown, threaded grooves 1201 are provided on opposite sides of the first shell 120, so that the lifting slider 130 can be supported and driven on both sides, and the lifting movement of the lifting slider 130 is more stable.

[0067] In some embodiments, such as Figure 7As shown, the moxibustion tool 200 includes a fixing cover 210, a fixing cylinder 220, a fixing frame 231, a fixing claw 232, a spring 233, and a push plate 234. The fixing cover 210 seals one end of the fixing cylinder 220. The fixing frame 231 is connected inside the fixing cylinder 220. One end of the fixing claw 232 is connected to the fixing frame 231, and the other end of the fixing claw 232 extends from the end of the fixing cylinder 220 away from the fixing cover 210. The end of the fixing claw 232 away from the fixing frame 231 is provided with a claw buckle 2321. The claw buckle 2321 is specifically an inwardly protruding step defined by an integral bend of the fixing claw 232. The elastic element is, for example, a spring 233. One end of the spring 233 is connected to the fixing frame 231, and the other end is provided with a push plate 234. The moxa can be clamped between the push plate 234 and the claw buckle 2321. The push plate 234 is used to press the moxa against the claw buckle 2321 under the elastic force of the spring 233. In this way, the moxa can be stably assembled, and the elastic force of the elastic element can keep the burning surface of the moxa roughly constant at the position of the claw buckle 2321, thus achieving a constant moxibustion surface effect. Furthermore, by keeping the burning surface at the position of the claw buckle 2321, the moxibustion tool 200 can be adjusted to an appropriate height by using the lifting slider 130, and the burning surface can be roughly maintained at that appropriate height without the need to frequently adjust the position and height of the lifting slider 130 as the burning length of the moxa changes.

[0068] Further optional, such as Figure 7 As shown, one end of the lifting slider 130 is defined as a cylindrical portion. On the moxibustion tool 200, a port is formed at the end of the fixed cylinder 220 away from the fixed cover 210. The cylindrical portion can be detachably inserted into the fixed cylinder 220 along the port, thereby achieving a detachable insertion connection between the lifting slider 130 and the moxibustion tool 200. Furthermore, the design of the assembly groove and the retaining edge facilitates the assembly of the lifting slider 130 with the first housing and ensures smooth lifting of the lifting slider 130. By allowing the side protrusion to be inserted into the threaded groove 1201 along the assembly groove, assembly damage to the side protrusion is reduced, resulting in better strength and load-bearing capacity. Thus, when the cylindrical portion of the lifting slider 130 is inserted into the fixed cylinder 220 of the moxibustion tool 200, the side protrusion is less prone to breakage, leading to better product quality and a longer lifespan.

[0069] Further optional, such as Figure 1 and Figure 7 As shown, a flexible element 140 is nested on the outer side of the cylindrical part. The flexible element 140 is, for example, a rubber element, a silicone element, or, specifically, an O-ring. When the cylindrical part is nested into the fixed cylinder 220, the flexible element 140 elastically abuts against the outer side of the cylindrical part and the inner side of the fixed cylinder 220, thereby making the detachable connection between the lifting slider 130 and the moxibustion tool 200 more stable. In this way, the moxibustion tool 200 is less likely to be poured out of the moxibustion cup 100, making it safer to use and providing a better user experience.

[0070] In some embodiments, combined Figure 1 and Figure 7 It is understood that the second shell 110 is provided with a first opening 112, and one end of the first shell 120 away from the first cover 150 passes through the first opening 112 and extends to the outside of the second shell 110. The extended end of the first shell 120 is provided with a base 122, and the base 122 can abut against the second shell 110.

[0071] The second shell 110 has a second opening 113 at the end away from the base 122. The moxibustion cup 100 also includes a second cover 160, which is connected to the second shell 110 and seals the second opening 113. The first cover 150 and part of the first shell 120 are located in the space enclosed by the second shell 110 and the second cover 160.

[0072] Specifically, the movement of the first shell 120 along the insertion direction of the first opening 112 is limited by the base 122 abutting against the second shell 110, and the movement of the first shell 120 along the extension direction of the first opening 112 is limited by the first cover 150 abutting against the second shell 110.

[0073] In this way, one end of the first shell 120 can be inserted into the second shell 110 along the first opening 112 until the base 122 abuts against the second shell 110. Then, the first cover 150 is installed at the inserted end of the first shell 120, and the second cover 160 is then closed with the second opening 113. The moxibustion cup 100 is simple and convenient to assemble. In the assembled structure, a part of the second shell 110 is confined between the first cover 150 and the base 122, realizing the connection between the second shell 110 and the first shell 120 and the confinement in two axial directions. The assembly between the first shell 120 and the second shell 110 is more stable and firm. Moreover, the first cover 150 is hidden in the space enclosed by the second cover 160 and the second shell 110. The first cover 150 and the first shell 120 are not easily disassembled by mistake. The reinforcement effect of the first shell 120 and the threaded groove 1201 on the first shell 120 is more reliable, which can further reduce the risk of deformation of the first shell 120.

[0074] Further optional, such as Figure 7As shown, the second cover 160 defines an inlet / outlet 161 for the moxibustion tool 200 to enter or exit the moxibustion cup 100. The cylindrical portion of the lifting slider 130 is positioned opposite to the inlet / outlet 161. Using a detachable insert assembly structure (i.e., the cylindrical portion, the fixed cylinder 220, and the flexible component 140) between the moxibustion tool 200 and the lifting slider 130, when assembling the moxibustion tool 200, simply insert the moxibustion tool 200 into the moxibustion cup 100 along the inlet / outlet 161 and press it further downwards so that the fixed cylinder 220 nests inside the outer side of the cylindrical portion of the lifting slider 130. This provides convenient assembly and disassembly, repeated assembly and disassembly, good blind assembly capability, and good error prevention, resulting in a better user experience. To disassemble the moxibustion tool 200 from the moxibustion cup 100, simply pull out the moxibustion tool 200 to separate the fixed cylinder 220 from the cylindrical portion of the lifting slider 130.

[0075] In other embodiments, the second cover 160 may be omitted, and the first cover 150 may be connected to the second shell 110, with the first cover 150 covering one end of the second shell 110 (that is, the first cover 150 covers the second opening 113 of the second shell 110). In this case, the inlet and outlet 161 may also be set on the first cover 150.

[0076] In some embodiments, such as Figure 6 As shown, the base 122 forms a moxibustion opening 1224, and the space enclosed by the first shell 120 is connected to the moxibustion opening 1224. Multiple first ventilation holes 1221 are arranged around the moxibustion opening 1224 on the base 122, with the holes spaced circumferentially. The space enclosed by the first shell 120 is connected to the environment through the first ventilation holes 1221. In this way, the first shell 120 can receive air through the first ventilation holes 1221 on the base 122, thereby supplementing the burning moxa inside the first shell 120, enhancing the combustion effect of the moxa, and thus improving the therapeutic effect of moxibustion.

[0077] And combined Figure 7 Understandable, Figure 7 The diagram illustrates the cross-sectional structure of the moxibustion device 10, and includes... Figure 7 The curve roughly indicates the airflow direction of the first shell 120. The first ventilation hole 1221 is set around the moxibustion port 1224 formed by the base 122. While supplementing the air for the burning of the moxa, the air entering along the first ventilation hole 1221 can push down the moxa smoke produced by the burning moxa, so that the moxa smoke has a better contact effect with the skin, and further enhances the therapeutic effect of moxibustion.

[0078] Further optional, such as Figure 7As shown, the moxibustion cup 100 also includes a connecting seat 170 and a ash-collecting mesh 180. Specifically, the connecting seat 170 is connected to the base 122 and is located at the moxibustion port 1224. The connecting seat 170 has a through channel 171 with an outlet end that is lower than the connection point between the space enclosed by the first shell 120 and the first ventilation hole 1221. The ash-collecting mesh 180 is connected to the connecting seat 170 and covers the channel 171. The ash-collecting mesh 180 can collect ash from the moxa, reducing the risk of burns to the skin being treated. Furthermore, since the outlet end of the channel 171 is lower than the connection point between the space enclosed by the first shell 120 and the first ventilation hole 1221, the air entering through the first ventilation hole 1221 has a better downward pressure effect on the moxa smoke, further prolonging the contact time between the moxa smoke and the skin and further enhancing the moxibustion effect.

[0079] Furthermore, the user can hold the second shell 110 and rotate the base 122 or connecting seat 170 of the first shell 120 (or, when holding the base 122 or connecting seat 170 of the first shell 120 and rotating the second shell 110), so that when the first shell 120 and the second shell 110 rotate relative to each other, the lifting slider 130 (i.e., the lifting slider 130) can be driven to rise or fall within the moxibustion cup 100. Through the lifting and lowering movement of the lifting slider 130, the position and height of the moxa object mounted on the lifting slider 130 can be adjusted accordingly. This allows for the adjustment of the distance between the burning surface of the moxa object and the surface of the skin being treated, thereby adjusting the perceived temperature of the skin surface being treated according to needs, better meeting the different temperature requirements of the user, and making the operation simple and convenient.

[0080] Further optional, such as Figure 1 As shown, a fastening part 1225 is protruding on the inner wall of the moxibustion port 1224. An assembly fastener 172 is provided at one end of the connecting seat 170, extending into the moxibustion port 1224 and engaging with the fastening part 1225. A first fastener 173 and a second fastener 174 are provided within the channel 171 of the connecting seat 170, staggered between them. The ash-collecting mesh 180 is engaged between the first fastener 173 and the second fastener 174. Thus, the ash-collecting mesh 180 can be connected to the base 122 of the first shell 120 using a single injection-molded connecting seat 170, simplifying the product structure and making assembly easier. Furthermore, the engaging connection allows users to disassemble the connecting seat 170 or the ash-collecting mesh 180 for emptying ash or cleaning, making the product simpler and more user-friendly.

[0081] Optionally, the first ventilation hole 1221 is vertically oriented or inclined downwards. This allows air to enter the first shell 120 without requiring an opening in the second shell 110, and the first ventilation hole 1221 is not obstructed by the second shell 110. Furthermore, the vertically oriented or inclined downwards first ventilation hole 1221 on the base 122 makes the internal structure of the moxibustion cup 100 less visible. This balances the high efficiency of air intake in the first shell 120 with the aesthetic appeal of the moxibustion cup 100, resulting in a more refined product. It also offers the advantages of simple structure and low cost.

[0082] Further examples, such as Figure 6 As shown, at least a portion of the side surface of the base 122 is an arc-shaped surface, and the base 122 transitions along the arc-shaped surface to a structure that is wider at the top and narrower at the bottom. That is, the side surface of the base 122 has an arc-shaped transition structure that is smaller at the bottom and larger at the top. This facilitates the setting of a vertical or downward-sloping first ventilation hole 1221 on the base 122, and makes the internal structure of the moxibustion cup 100 less visible, thus better maintaining the aesthetics of the moxibustion cup 100 and making the product more refined.

[0083] Further examples, such as Figure 6 As shown, the end of the base 122 away from the second shell 110 is narrower than the end closer to the second shell 110. A bottom surface is provided at the end of the base 122 away from the second shell 110, as shown... Figure 8 As shown, a portion of the edge contour of the first ventilation hole 1221 intersects the arc-shaped surface, while another portion intersects the bottom surface. This makes the air intake direction of the first ventilation hole 1221 more multi-dimensional, allowing for a wider air intake range and improving the air intake efficiency of the first shell 120 along the first ventilation hole 1221. This better provides oxygen for the burning of the moxa inside the first shell 120. Simultaneously, the internal concealment effect of the first ventilation hole 1221 is also ensured, making the internal structure of the moxibustion cup 100 less visible along the first ventilation hole 1221.

[0084] In some embodiments, combined Figure 4 and Figure 7 It is understood that a gap 101 is defined between the first shell 120 and the second shell 110. The first shell 120 is provided with a second ventilation hole 1202, and the space enclosed by the first shell 120 communicates with the gap 101 through the second ventilation hole 1202. In this way, the first shell 120 can take in air through the second ventilation hole 1202 and the gap 101 between the first shell 120 and the second shell 110, further increasing the amount of air inside the first shell 120 and further improving the combustion effect of the moxa. Moreover, even if the second shell 110 does not have an opening, the first shell 120 can still take in air from the side, thus achieving the effect of air entering the first shell 120 from the side without affecting the aesthetics of the second shell 110, resulting in a better air supply effect for the combustion of the moxa.

[0085] Further optional, such as Figure 4 As shown, the second ventilation hole 1202 is located at one end of the first shell 120 near the base 122; there is a certain amount of axial movement between the first shell 120 and the second shell 110. This axial movement between the first shell 120 and the second shell 110 increases the efficiency of air intake from the environment through the gap 101 between them, resulting in better air intake through the second ventilation hole 1202. Furthermore, by placing the second ventilation hole 1202 at one end of the first shell 120 near the base 122, the path between the second ventilation hole 1202 and the environment along the gap 101 is shorter, leading to higher air intake efficiency and meeting the needs of scenarios requiring greater oxygen for combustion.

[0086] In some embodiments, such as Figure 7 As shown, a third ventilation hole 162 is provided on the second cover 160, and the space enclosed by the first shell 120 is connected to the environment through the third ventilation hole 162. The third ventilation hole 162 allows the moxibustion cup 100 to exhaust air outwards, promoting air circulation within the moxibustion cup 100 and ensuring timely air intake, thus better guaranteeing the combustion effect of the moxa. The third ventilation hole 162 is located on the second cover 160, which is situated at the end furthest from the base 122. This allows most of the moxa smoke to be promptly discharged through the third ventilation hole 162 via the rising hot air path, and minimizes the resistance to air intake at the second ventilation hole 1202 during the smoke's discharge, thus ensuring the efficient air intake of the first shell 120.

[0087] Further optionally, the second cover 160 includes an inner cover 1601 and an outer cover 1602, with the inner cover 1601 forming an entrance / exit 161. The lifting slider 130 is driven to move up and down by relative rotation between the first shell 120 and the second shell 110, as shown below. Figure 10 As shown, when the moxibustion tool 200 is raised to a higher position by the lifting slider 130, a portion of the moxibustion tool 200 (specifically, the fixed cover 210 of the moxibustion tool 200) is pushed out along the inlet 161 formed by the inner cover 1601. This facilitates the user in removing the moxibustion tool 200. Preferably, anti-slip ribs 211 are provided on the fixed cover 210. Of course, anti-slip grooves can also be used to further prevent slippage when the user handles the moxibustion tool 200. For example, it is easier for the user to pull the moxibustion tool 200 out of the moxibustion cup 100 by holding the fixed cover 210. Correspondingly, when the moxibustion tool 200 is raised to a higher position by the lifting slider 130, the burning surface of the moxa is relatively further away from the ash-collecting mesh 180. This means that the burning surface of the moxa is relatively further away from the surface of the skin being treated, which can reduce the surface temperature of the skin being treated. Figure 9As shown, when the moxibustion tool 200 is lowered to a lower position under the drive of the lifting slider 130, the moxibustion tool 200 sinks into the moxibustion cup 100, so that the burning surface of the moxa is relatively closer to the ash collection net 180, and correspondingly, the burning surface of the moxa is relatively closer to the surface of the skin to be treated, which can increase the surface temperature of the skin to be treated.

[0088] like Figure 7 As shown, the inner cover 1601 is nested within the outer cover 1602. The inner cover 1601 and the outer cover 1602 form a filter cavity 163. The outer cover 1602 has a third ventilation hole 162 that communicates with the filter cavity 163. The second cover 160 may further include a filter element, allowing the smoke to pass through the filter element before being discharged through the third ventilation hole 162, thus reducing unpleasant experiences such as irritation from the smoke.

[0089] Further optional, such as Figure 7 As shown, the filter chamber 163 is a cavity with an open bottom, and the space enclosed by the bottom opening of the filter chamber 163 and the first shell 120 is connected. The top of the first cover 150 is opposite to the bottom opening of the filter chamber 163, which allows the filter element inside the filter chamber 163 to be confined within the filter chamber 163. The second shell 110 is provided with a locking protrusion 1131 at the second opening 113, and the outer cover 1602 is provided with a groove 164 on the inner side of the bottom. The second opening 113 and the outer cover 1602 are engaged together by the locking protrusion 1131 and the groove 164, which is convenient for assembly and facilitates the replacement of the filter element inside the filter chamber 163.
