Description

Technical Field

[0001] This utility model relates to a moxibustion device. Background Technology

[0002] The smoke produced during moxibustion is called moxibustion smoke. Moxibustion smoke contains volatile oils from mugwort (eucalyptol, camphor), tar from incomplete combustion, carbon monoxide, and particulate matter (PM2.5). Among them, some components of the volatile oils, such as mugwort essential oil, are considered to have antibacterial and anti-inflammatory effects, but they can irritate the respiratory system and easily cause symptoms such as cough and sore throat.

[0003] People now have a clearer understanding of moxibustion smoke. In a well-ventilated environment, moxibustion smoke can dissipate quickly, posing a low risk. However, in a sealed environment, moxibustion smoke can irritate the respiratory tract and also cause PM2.5 levels to exceed the standard in that enclosed space.

[0004] Currently, the main methods for dealing with moxibustion smoke are to optimize the surrounding environment and usage methods. For example, ensuring that it is used in a well-ventilated environment or controlling the frequency or duration of moxibustion (e.g., the number of moxibustion sessions per week should not exceed 3 times, and the duration of a single moxibustion session should not exceed 30 minutes). Contraindications have also been identified. However, these measures are mainly used to control the usage environment and usage methods, and the normal usage of moxibustion is limited.

[0005] Therefore, to reduce the limitations of moxibustion usage caused by the smoke, some methods include providing a storage bag for the moxibustion device. The device is placed inside the bag, which is typically made of fabric and can be worn directly against the skin. In this method, the bag is used to block smoke, but its actual smoke-blocking effect is poor. This is because these bags are generally made of cotton or non-woven fabric, which has extremely limited filtering capacity. Furthermore, the bag has a certain degree of adsorption, resulting in a strong residual smoky smell after use. Additionally, ash and other residues accumulate on the bag, making it difficult to clean and leading to a poor user experience.

[0006] Another method to reduce the limitations of moxibustion usage caused by the smoke is to install a filter device on the moxibustion device. Typically, Chinese patent document CN222510531U discloses a scalding and smoke-controlling moxibustion box, which includes a moxibustion box body that is movably installed in a heat-insulating shell. A heat-insulating sealing cover is provided on one side of the moxibustion box body, and smoke treatment components are symmetrically arranged on both sides inside the heat-insulating sealing cover. The smoke treatment components include an installation cavity, in which a semi-circular carrier is provided. An activated carbon adsorption mesh is detachably installed in the semi-circular carrier, which can be understood as an adsorption filler, to adsorb the smoke generated when the moxa or moxibustion stick is burned.

[0007] Currently, incorporating devices for adsorbing moxibustion fumes into moxibustion devices has become a common practice, with various installation methods available. However, most of these devices are relatively complex. For example, in the aforementioned Chinese patent document CN222510531U, the activated carbon adsorption mesh for fumes is installed from both sides within a heat-insulating sealing cover. While the activated carbon adsorption mesh can be easily installed and removed, the space for positioning and installing it is relatively small. Furthermore, as mentioned earlier, tar and other substances easily deposit on the inner surface of the moxibustion device where it contacts the moxibustion fumes. The relatively complex cavity or structure can hinder the cleaning of substances such as tar. Utility Model Content

[0008] In view of this, the purpose of this utility model is to provide a moxibustion device with a relatively simple structure and easy cleaning, which has the function of filtering moxibustion smoke.

The extending direction of the connecting ribs is parallel to the axial direction of the center seat.

[0025] The reed has an arc-shaped portion; correspondingly, one arc-shaped portion on each of the two reeds faces each other to clamp the moxa stick;

[0026] Furthermore, the end of the reed has an inlet portion.

[0027] Optionally, the central seat is further provided with a limiting component for supporting the moxa stick to limit the amount of moxa stick embedded.

[0028] Optionally, the limiting component is a support piece formed by punching and folding a sheet of metal.

[0029] Optionally, the detachable connection structure is:

[0030] The first detachable connection structure has a fixing hole in the center of the upper or lower bracket, and the upper or lower cover is correspondingly provided with screw holes or studs, providing a screw that mates with the screw hole or a nut that mates with the stud to fix the upper or lower bracket through the fixing hole; or

[0031] The second detachable connection structure has an upper or lower bracket with an irregularly shaped central hole. The upper or lower bracket is connected to an irregularly shaped buckle via a connector. The irregularly shaped central hole allows the buckle to pass through and locks after the upper or lower bracket rotates a predetermined angle; or

[0033] Corresponding to the first detachable connection structure and the second detachable connection structure, the upper filter cotton and the lower filter cotton are provided with a central hole for studs or screws to pass through.

[0034] Optionally, the periphery of the fixing hole is provided with protrusions, bumps or stop pins for limiting the rotation angle of the upper or lower bracket.

[0037] Corresponding to the third detachable connection structure, the curvature of the surface of the upper or lower bracket that mates with the corresponding concave or convex surface is greater than or equal to the curvature of the corresponding concave or convex surface.

[0038] Optionally, the upper cover and lower cover can be fitted together as follows:

[0039] In the first fitting method, the upper cover is installed on the lower cover via a side hinge, and the upper cover and the lower cover are provided with a latch on the side opposite to the side hinge;

[0040] The second fitting method involves an upper cover with a cylindrical upper shell and a lower cover with a cylindrical lower shell, the upper and lower shells being nested together using an interference fit; or

[0041] The third fitting method is that the upper cover has a cylindrical upper shell and the lower cover has a cylindrical lower shell. The inner cylindrical surface of the upper shell is a cylindrical surface and the inner cylindrical surface of the lower shell is a cylindrical surface. One of the cylindrical surfaces is an external thread and the other cylindrical surface is an internal thread. The upper cover and the lower cover are connected based on the engagement of the internal and external threads.

[0043] The lower air vents are distributed within the concave curved surface.

[0044] Optionally, the concave surface has a raised texture.

[0045] The moxibustion device according to this embodiment uses a filter cotton instead of a filter filler. The filter cotton is processed into a sheet shape, allowing it to be clamped within the upper and lower clamping structures. The upper clamping structure is formed by the fit between the lower surface of the upper cover and the upper support. The upper air vent formed on the upper cover is shielded by the upper filter cotton clamped within the upper clamping structure. Thus, when the smoke exits through the upper air vent, it is filtered by the upper filter cotton, reducing the impact of moxibustion smoke. The upper support and the upper cover are detachably connected, allowing the upper support to be removed for replacing the filter cotton and cleaning the inner surface of the upper cover and the upper support. Since the upper filter cotton does not require complex cavities, the inner surface of the upper cover is relatively smooth and free of narrow gaps, facilitating cleaning. The lower cover and lower clamping structure are similar. Furthermore, since the upper and lower supports are mainly used to hold the sheet-like material, such as the upper filter cotton, without the need for complex cavities or gaps, the structure is relatively simple.

[0062] It should be noted that moxibustion devices have been widely used in China, and their names have become standardized. Moxibustion devices are also known as moxibustion therapy induction devices. They are mainly classified into moxibustion jars and moxibustion boxes; the moxibustion device based on this utility model embodiment is mainly applicable to moxibustion boxes.

[0063] The basic materials of moxibustion devices are mainly stainless steel, copper, silicone-ceramic, wood, wood, etc. There are many types. At present, some moxibustion devices do not require the moxa stick support, while others have a moxa stick support. The presence of a moxa stick support is conducive to the combustion of the moxa stick. Even if there is no moxibustion support, the moxa stick has good combustion performance and is not easy to extinguish on its own.

[0064] In the embodiments of this utility model, the material of the moxibustion device body can be the aforementioned stainless steel, copper, silicone-ceramic, wood, etc. Obviously, the moxibustion device based on the embodiments of this utility model does not have special requirements for the material, although metal material is preferred in more preferred embodiments.

[0065] Regarding the choice of materials, the buckle 42 is formed or connected on the upper cover plate 41. For metal materials, welding can be used directly. For materials such as wood or wood, holes can be pre-drilled and the buckle 42 can be fixed to the upper cover plate 41 by screws or rivets. Obviously, there are corresponding implementation methods for any material.

[0066] It should be noted that even without a moxibustion device, moxibustion can be performed using handheld moxa sticks. Using a moxibustion device instead of a handheld device not only frees up the hands but also helps to control the direction of the effective ingredients in the moxibustion.

[0067] Moxibustion devices typically have defined upper and lower positions, such as... Figure 1The moxibustion device shown has an upper cover 4 and a lower cover 3. During moxibustion, the active ingredients tend to decrease in concentration. Therefore, for example, the vent 31 on the lower cover 3 will release the active ingredients. During combustion, some of the relatively light components may be released through the upper cover vent 44 on the upper cover 4. This is common knowledge in the art and will not be elaborated further here.

[0068] In some implementations, the moxibustion device may also have a side hole as an air inlet, but in the embodiments of this utility model, a side hole may or may not be provided.

[0069] It should be understood that moxibustion devices typically include a body and a lid. In the embodiments of this utility model, this traditional structure, which includes a body and a lid, can be adopted. In some implementations, the two main parts of the moxibustion device used to construct the cavity 9 are not distinguished as primary and secondary, and can be referred to as the upper cover 4 and the lower cover 3. However, in the embodiments of this utility model, the upper cover 4 and the lower cover 3 are only used to distinguish the two main parts, and do not mean that they cannot be the body and the lid.

[0070] The upper cover 4 and the lower cover 3 are mainly used to distinguish their orientation when in use or when placed. The lower cover 3 specifically refers to the state when it is relatively close to the human body, while the upper cover 4 is in a state relatively far away from the human body.

[0071] Among them, the upper cover 4 has an upper cover plate 41, and its main body can only have the upper cover plate 41. When it only has the upper cover plate 41, its configuration is consistent with the aforementioned realization of having a vessel body and a vessel cover.

[0072] The upper cover plate 41 has upper air holes distributed on it, such as Figure 5 The vent 44 shown in the diagram is referred to as the vent 44 in the following text.

[0073] exist Figure 1 and Figure 5 In the illustrated structure, the upper vents are distributed in a ring array on the upper cover plate 41 of the upper cover 4, with the central part left blank for fixing the upper buckle 42. In addition, when the flue gas with a certain temperature overflows from the upper vents, it will exchange heat with the upper cover 4. This relatively widely distributed upper vent can make the temperature of the upper cover 4 relatively uniform and avoid local overheating.

[0074] Although the metal top cover 4 has good thermal conductivity, heat conduction alone will still create a certain temperature field. The relatively evenly distributed vents help to disperse heat. At the same time, the presence of the vents can guide some of the moxibustion smoke to escape. The vents are covered by the upper filter cotton 5. In other words, the relatively evenly distributed vents and the relatively large area of ​​the upper filter cotton 5 are conducive to its filtering effect, avoiding only localized effects.

[0075] There may be only one air hole. Setting only one air hole is the conventional choice for current moxibustion devices. The moxibustion device based on the embodiment of this utility model can also adopt this setting method.

[0076] exist Figure 1 In the illustrated structure, the top cover 4 has five rings of top cover air holes 44 arranged in a circular array. The spacing between the top cover air holes 44 on the same ring is approximately equal to the hole diameter. This distribution method can evenly disperse the incoming and outgoing air, and make the portion of the top filter cotton 5 that cooperates with the top cover 4 to perform the adsorption function account for a large proportion of the top filter cotton 5.

[0077] If we only consider air intake and exhaust, the air vent 44 on the top cover can be one, two, three, or four.

[0078] Regarding the hole position, if only one top cover vent 44 is provided, the single top cover vent 44 can be offset on one side of the top cover plate 33, and the offset side can be consistent with the head (burning end) of the horizontally placed moxa stick 8.

[0079] If there are two, three or four vent holes 44 on the top cover, the vent holes are evenly distributed on one side of the top cover plate 33, or evenly arranged in a ring around the central axis of the top cover plate 41.

[0080] Regarding the configuration of the vent 31 on the lower cover 3, please refer to the aforementioned configuration of the vent 44 on the upper cover, which will not be repeated here.

[0081] As an inherent configuration, the lower cover 3 and the upper cover 4 are assembled into a box structure, so the moxibustion device based on this utility model embodiment is mainly constructed as a moxibustion box.

[0082] The upper cover vent 44 on the upper cover 4 is mainly used for air intake, while the lower cover vent 31 on the lower cover 3 is mainly used for air exhaust. It should be noted that the main components of moxibustion smoke have a relatively high specific gravity and mainly appear by sinking. At the same time, it should be known that the burning of mugwort also produces other components and heats the air in the cavity 9, resulting in thermal convection. Therefore, gas will actually overflow from the upper cover vent 44, and some gas will also be introduced through the lower vent on the lower cover 3. Based on the embodiment of this utility model, the gas vent 31 mainly contains the effective components of moxibustion. Therefore, the gas vent 31 does not have a strict limiting function and is only used to distinguish it from the upper cover vent 44 on the upper cover 4.

[0083] An upper bracket 6 is provided to mate with the upper cover 3. Specifically, the upper bracket 6 mates with the upper cover 3 via the upper cover plate 41 of the upper cover 3. Since the upper bracket 6 is located inside the cavity 9, it mates with the lower surface of the upper cover plate 41 to form an upper clamping structure.

[0084] Based on the description of the principle of the utility model, the cooperation between the upper support 6 and the upper cover 3 is mainly used to fix the upper filter cotton 5. The distribution range of the upper filter cotton 5 is adapted to the distribution range of the upper air holes. However, the sheet-like structure of the upper filter cotton 5 is a necessary structure of this utility model. Therefore, the upper support 6 should be functionally suitable for fixing the sheet-like upper filter cotton 5, while avoiding the upper air holes. Therefore, the upper support 6 is basically sheet-like in shape to facilitate holding the upper filter cotton 5 over a relatively large area, and should also have a structural part that exposes the upper air holes, such as... Figure 6 and Figure 7 The upper clearance hole 64 is shown.

[0085] Meanwhile, the basic structure of the upper support 6 can also be a mesh. The mesh holes on the mesh can play the same role as the upper clearance holes 64. Even if the mesh wires have a certain shading effect, the mesh hole density on the mesh is relatively large, which usually produces a good exposure effect.

[0086] Therefore, in general, both the relief hole 64 and the mesh on the mesh are collectively referred to as structures used to expose the upper air vents.

[0087] It should be understood that, in terms of simply holding the upper filter cotton 5, the strength requirement for the upper support 6 itself is relatively low. Therefore, a relatively thin metal mesh, such as a 0.5mm thick stainless steel mesh (standard name: stainless steel plate mesh), with an opening ratio of 80%, is used. The rigidity of the mesh is sufficient to hold the upper filter cotton 5. At the same time, due to the relatively high opening ratio, the obstruction of the solid parts on the mesh does not affect the introduction or export of gas through the upper air holes.

[0088] If a mesh is used as the upper support 6 to hold the upper filter cotton 5, the opening ratio of the mesh should be no less than 60%.

[0089] The mesh that forms the functional part of the upper support 6 that holds the upper filter cotton 5 can also be a woven mesh, preferably a metal woven mesh with a wire diameter of less than or equal to 0.5 mm.

[0090] The aforementioned upper support 6, which holds the upper filter cotton 5, can be called the upper pressure plate 62. When the upper pressure plate 62 is made of mesh, for example, the upper clamp 61, which is the mounting base of the upper pressure plate 62, can be fixed to the mesh-shaped upper pressure plate 62 by welding or by riveting.

[0091] Understandably, the opening in the upper pressure plate 62 can be formed by punching or laser drilling on a metal sheet. The opening can be partially created while retaining... Figure 6The upper center seat 68 shown in the figure, under this condition, has sufficient strength to support the installation of the upper clamp 61, for example.

[0092] Figure 6 and Figure 7 The upper pressure plate 62 shown in the figure is formed by a punching process from a stainless steel round plate. Part of the plate is punched off from a round metal plate according to the distribution of the upper air holes to form the upper clearance hole 64 shown in the figure.

[0093] It should be noted that the solid parts in the upper pressure plate 62, including the concentric ring part in the figure, the upper center seat 68, and the ribs used to connect the rings in the concentric ring part and the upper center seat 68, have a certain shielding effect. However, in the embodiments of this utility model, it is not required that all the upper air holes be exposed, but most of the upper air holes can be exposed, which can fully meet the usage requirements.

[0094] exist Figure 6 and Figure 7 In the illustrated structure, the upper pressure plate 62, formed by punching a metal disc, has an opening ratio of more than 50%, and the outermost ring of the annular portion can hold the edge of the upper filter cotton 5. Most of the remaining portion of the upper pressure plate 62 can be fully perforated, thereby reducing the impact on the amount of upper air hole obstruction.

[0095] In particular, if the number of upper vents is small, such as one, two, three, or four, an independent upper clearance vent 64 can be opened accordingly.

[0096] The above description of the upper support 6 and the upper pressure plate 62 contained in the upper support 6 can be applied to the lower support 2 and the lower pressure plate 21. The lower support 2 and the lower pressure plate 21 will not be described again here.

[0097] Filter cotton, a type of air filtration media, is commonly used for smoke filtering. There are many types of filter cotton, which can be categorized into four types based on the material: synthetic fiber filter cotton, non-woven fabric filter cotton, glass fiber filter cotton, and activated carbon filter cotton. Synthetic fiber filter cotton and activated carbon filter cotton are preferred. Based on filtration efficiency, filter cotton can be divided into pre-filter cotton and medium-efficiency filter cotton. According to the principle of this invention, pre-filter cotton can meet the filtration requirements, but the relatively more efficient but more expensive medium-efficiency filter cotton can still be selected.

[0098] Activated carbon filter cotton is currently widely used, with a thickness of 1~20mm. Based on the embodiments of this utility model, the upper filter cotton 5 and the lower filter cotton 1 can be activated carbon filter cotton with a thickness of 1~3mm, with a thickness of no more than 1.5mm being preferred.

[0099] It should be noted that a type of filter cotton specifically designed for filtering moxibustion smoke has appeared on the market, with a thickness of 1-8mm. Based on the concept of this utility model embodiment, a relatively thin filter cotton specifically designed for filtering moxibustion smoke is selected and cut into, for example, circular shapes to form circular sheets. The trade name of this type of product is generally activated carbon smokeless cotton flame retardant fireproof filter moxibustion smoke filter cotton, or other similar names.

[0100] Correspondingly, both the upper filter cotton 5 and the lower filter cotton 1 are used as consumables and can be replaced periodically.

[0101] The aforementioned use of relatively thin filter cotton is mainly for air resistance, which should be clearly understood by those skilled in the art and will not be elaborated upon here.

[0102] Regarding the cutting of the aforementioned filter cotton, it is preferred to cut it into circular pieces. As can be seen from the previous description, for example, the shape of the upper filter cotton 5 mainly depends on the distribution of the upper air pores. Based on this, those skilled in the art can easily determine how to cut the filter cotton into a predetermined shape to obtain, for example, the upper filter cotton 5, which will not be elaborated here.

[0103] Regarding the lower bracket 2, it is mainly used to cooperate with the upper surface of the lower cover 3 to form a lower clamping structure. For other functions, please refer to the description of the upper bracket 6 and the upper cover 4 mentioned above, which will not be repeated here.

[0104] Similarly, the lower filter cotton 5 also adopts a sheet structure, which is sandwiched between the lower cover 3 and the lower support 2, and covers the lower air hole.

[0105] Furthermore, both the clamping structure and the lower clamping structure are detachable connection structures. The detachable connection structure here is obviously the detachable connection between the upper bracket 6 and the upper cover 4 and the detachable connection between the lower bracket 2 and the lower cover 3. Thus, after removing the upper bracket 6 and the lower bracket 2, the upper cover 4 and the lower cover 3 with relatively regular inner contours can be cleaned.

[0106] like Figure 2 and 5 As shown, the upper cover 4 has an upper shell 43 and an upper cover plate 41 for sealing the upper shell 43. The upper cover plate 41 is illustrated in the figure as a two-segment spherical structure. In other words, the inner surface of the upper cover 4 includes the inner cylindrical part corresponding to the upper shell 43 and the lower surface of the upper cover plate 41. The lower surface of the upper cover plate 41 is approximately spherical or other upward concave curved surface. After removing the upper support 6, the cylindrical surface and the concave curved surface are relatively simple and smooth in terms of structure, without narrow space, and easy to clean.

[0107] Even if there is a 42-degree angle deduction, it is only a small, localized area and has little impact on the overall cleanup.

[0108] The same applies to the lower cover 3, which will not be elaborated upon here.

[0109] Because of the presence of, for example, a lower buckle 34 or an upper buckle 42, the corresponding upper filter cotton 5 can have an upper filter cotton center hole 51, and the lower filter cotton 1 has a lower filter cotton center hole 11. The size of the opening is just enough to allow the lower buckle 34 or the upper buckle 42 to pass through.

[0110] Whether the upper filter cotton 5 or the lower filter cotton 1 needs to have holes depends on, for example, the connection relationship and structure between the upper bracket 6 and the upper cover 4. The aforementioned requirement regarding, for example, the center hole 51 of the upper filter cotton is only a proprietary requirement in some embodiments and does not apply to all embodiments.

[0111] For example, in some embodiments, the connection between the upper support 6 and the upper cover 4 is manifested at the edge, and the connection at the center can be omitted. Under this condition, it is not necessary to open the center hole 1 of the upper filter cotton 5.

[0112] Correspondingly, whether the lower filter cotton 1 has holes is the same as above, and will not be repeated here.

[0113] In addition, a moxa stick clamp is also provided inside the cavity 9, such as Figures 5-7 ,as well as Figure 9 The upper clamp 61 shown is mounted on the upper bracket 6.

[0114] In some embodiments, the moxibustion stick clamp can also be set on the lower support 2.

[0115] Since the moxa stick clamp is mainly a clamping structure, placing the moxa stick clamp on, for example, the upper bracket 6, allows the moxa stick clamp to be used as a force application point for assembling and disassembling the upper bracket 6, for example, by pinching it with two fingers. Figure 6 The two springs of the upper clamp 61 that constitute the moxa stick clamp shown are used to pick up or put down the upper support 6 or rotate the upper support 6. At this time, for example, the upper clamp 61 is used as both a clamp for the moxa stick and a gripping part for picking up, putting down and assembling the upper support 6.

[0116] In some other embodiments, the moxa stick clamp can be set on the upper cover 4 and / or the lower cover 3, as long as the moxa stick is located approximately in the middle of the cavity 9.

[0117] In some embodiments, the moxibustion stick clamp is only provided on the upper support 6. In these embodiments, a handle 22 can be provided on the lower support 2. The handle 22 is formed on the lower support 2 by punching. The handle 22 is a rectangular piece structure with two pieces.

[0118] If the moxibustion stick clamp is set on, for example, the upper cover 4, the moxibustion stick clamp can be set at the center of, for example, the upper cover plate 41 and suspended downward, or it can be set on the upper shell 43 and extend laterally.

[0119] Similarly, the same applies to the setting of the moxibustion stick clamp on, for example, the lower cover 3.

[0120] If the moxibustion stick clamp is placed on the upper cover 4 or the lower cover 3, assembly interference issues need to be considered, such as... Figure 2 As shown, if the moxibustion stick clamp is placed at the center of the upper cover plate 41 and suspended downwards, it is not affected by the assembly between the upper cover 4 and the lower cover 3. If it is placed on the upper casing 43 of the upper cover plate 41, then... Figure 2 The scheme of fastening the upper cover 4 to the lower cover 3 in the example structure is not applicable. In this case, it can be slightly modified so that the lower cover 3 is fastened to the upper cover 4. Under this condition, there will be no assembly interference.

[0121] Furthermore, if the moxibustion stick clamp is set on the upper cover plate 41, the assembly of the upper filter cotton 5 and the size of the opening of the upper filter cotton 5 also need to be considered, that is... Figure 5 The center hole 51 of the upper filter cotton shown in the figure only needs to be able to avoid the upper clamp 61.

[0122] Furthermore, if the upper clamp 61 itself constitutes a fastener, for example, if the upper clamp 61 is a U-shaped structure, in addition to the two springs, it also includes a base plate that connects the two springs at the bottom, and the base plate can, for example, have threaded holes. A stud is welded to the upper cover, and the center hole 51 of the upper filter cotton only needs to allow the stud to pass through. The parts, including the upper bracket 2, are directly held in place by the base plate through the engagement of the threaded hole and the stud.

[0123] The following description of the general structure of the upper support 6 and the lower support 2 will be based on the upper support 6 as an example. The two have the same basic structure. Therefore, the following description will only use the upper support 6 as an example for detailed explanation. The lower support 2 can be referred to and applied accordingly.

[0124] exist Figure 6 and Figure 7 In the illustrated structure, the upper support 6 has an upper central seat 68, and two annular portions are provided on the outermost periphery of the upper support 6. These two annular portions constitute the upper pressure plate 62 shown in the figure. The two annular portions are connected to each other and to the upper central seat 68 by radial connecting ribs.

[0125] The use of radial connecting ribs is mainly to facilitate the positioning of the upper clearance hole 64.

[0126] Figure 6 and Figure 7 The two annular sections are positioned on the outer periphery, primarily to ensure the reliability of the pressing of the upper filter cotton 5.

[0127] exist Figure 1 and Figure 2As can be seen in the illustrated structure, the upper cover 4 has a dome-shaped structure. The numerous annular sections facilitate pressing the upper filter cotton 5 onto the inner surface of the upper cover plate 41, which is the lower surface, so that the upper filter cotton 5 and the inner surface of the upper cover plate 41 fit relatively well.

[0128] If the top cover plate 41 of the top cover 4 is a flat plate, then only an outermost ring part is needed.

[0129] A certain space is formed between the rings and between the rings and the upper central seat 68. This space is called the ring space, and it is used to expose the upper vent, that is, to leave the upper vent unobstructed. For the sake of simplicity, in Figure 6 and Figure 7 The middle part is indicated as the upper clearance hole 64.

[0130] Regarding the manufacturing of the upper support 6, it is preferred to use metal sheet stamping. The preferred material for the upper support 6 is stainless steel. The blank is a round piece, and then the upper relief hole 64 is formed by stamping process, and then the burrs are removed.

[0131] In some embodiments, the clamping device, such as clamp 61 above, can be formed directly during the stamping process, such as... Figure 6 and Figure 7 In the middle, the connecting ribs include two relatively wide connecting ribs. During the punching process, elongated holes are punched out on the connecting ribs. The corresponding punched-out strips are connected to the upper center seat 68 and then folded upwards to form the shape.

[0132] In other embodiments, as mentioned above, the upper clamp 61 can be a pre-processed U-shaped part. The bottom plate of the U-shaped part is fixed to the upper cover 4 by studs set on the upper cover 4. At the same time, the bottom plate of the U-shaped part also serves as a pressure plate, pressing down the upper pressure plate 62 and the upper filter cotton 5 together.

[0133] In some embodiments, the upper clamp 61 can be a separate component, fixed to the upper center seat 68 by means of welding, for example.

[0134] Regarding the clamping of moxa sticks inside the moxibustion device, they can be clamped using a clamping method or a pin method. From the perspective of positioning and clamping, even if a pin-type structure is used, it still falls under the category of positioning and clamping.

[0135] And in Figure 6 and Figure 7 In the illustrated structure, the upper clamp 61 consists of two symmetrically arranged spring plates. This structure can clamp the moxa stick both horizontally and vertically. Figure 2 The image shows two states of the moxa stick, represented as vertical moxa stick 7 and horizontal moxa stick 8.

[0136] Furthermore, as mentioned above, by means of Figure 6 The roughly U-shaped upper clamp 61 can also serve as the operating part of the upper support 6.

[0137] Accordingly, such as Figure 6 and Figure 7 The connecting ribs are radial connecting ribs, there are four in total, arranged in a cross shape, one pair of which are relatively wide. The relatively wide pair of connecting ribs are punched into an upper clamp 61 based on the punching process, so that the extension direction of the connecting ribs is parallel to the normal direction of the center seat 68.

[0138] exist Figure 6 and Figure 7 In the illustrated structure, the two clamping arms of the upper clamp 61 are not straight arms, but this does not affect the description regarding their direction of extension. Furthermore, the springs constituting the clamping arms have arcuate portions; correspondingly, one arcuate portion on each of the two springs faces each other for clamping the moxibustion column. Furthermore, the ends of the springs flare outwards, forming V-shaped guide portions.

[0139] To reduce the negative impact of the moxa stick burning, a limiting component is provided on, for example, the upper center seat 68, to support the moxa stick and limit its embedding depth. Figure 6 The upper support piece 63 shown.

[0140] Upper support plate Figure 6 The illustrated structure is also based on, for example, the integral punching of a circular blank.

[0141] In some embodiments, if the connection between the upper bracket 6 and the upper cover plate 41 is, for example, a screw connection, the screw head can be located in the cavity 9, and in this case, the screw head can constitute the limiting component.

[0142] Regarding the aforementioned detachable connection structure, several preferred structures are described below. Other mechanically interchangeable structures will not be listed here.

[0143] Firstly, there is a first detachable connection structure. Corresponding to this first detachable connection structure, for example, the upper bracket 6 has a fixing hole in its center, and the upper cover 4 is correspondingly provided with a screw hole or stud, providing a screw that mates with the screw hole or a nut that mates with the stud to fix the upper bracket 6 through the fixing hole. The description of the stud has been mentioned above, and the same applies to the screw, only the elements are replaced, so it will not be described in detail here.

[0144] Similarly, the detachable connection structure also applies to the lower bracket 2. The assembly method and structure of the lower bracket 2 on the lower cover 3 will not be described in detail here.

[0145] Regarding the second optional detachable connection structure: for example, the upper bracket 6 has an irregularly shaped central hole, and the upper bracket 6 is connected to an irregularly shaped buckle via a connector, such as... Figure 6 and Figure 7 The upper buckle 42 shown has an irregularly shaped central hole for the buckle to pass through, and locks after the upper bracket 6 rotates a predetermined angle. The type of lock using an irregularly shaped buckle is primarily a cross lock, also known as a cross-shaped rotary lock or cross-shaped rotary screw lock. It relies on the similarity between the shape of the buckle and the shape of the irregularly shaped hole; any deviation in their rotation angles creates interference in the buckle's release direction, thus providing convenient and quick locking or unlocking. For example, a typical cross lock is a common irregularly shaped buckle lock; after passing the buckle through the keyhole, rotating it 90° locks it in place.

[0146] The first two optional detachable connection structures primarily employ a center connection method. The third optional detachable connection structure uses an edge connection method. A fan-shaped single-sided buckle is provided around the outer perimeter of the portion where the upper cover 4 mates with the upper bracket 6. Two or three single-sided buckles are preferred. A single-sided buckle notch is provided on the outer edge of the corresponding upper bracket 6. The upper bracket 6 is positioned through the single-sided buckle notch and rotated, causing the single-sided buckle to press against the outer edge of the corresponding upper or lower bracket. This third detachable connection method is also suitable for quick assembly and disassembly.

[0147] Correspondingly, corresponding to the first connecting structure and the second detachable connecting structure, the upper filter cotton 5 is provided with a central hole for studs or screws to pass through.

[0148] In some embodiments, a composite connection method may also be adopted, that is, the first detachable connection structure and the third detachable connection structure are used simultaneously.

[0149] Given that the aforementioned detachable connection structure requires rotation, for example, the upper bracket 6, in order to control the rotation angle of the upper bracket 6 and thereby achieve better position control, the periphery of the fixing hole is provided with protrusions, bumps, or stop pins to limit, for example, the rotation angle of the upper bracket. Figure 6 The upper limit bump 66 is shown in the figure.

[0150] The upper limit bump 66 can be formed by means of a protrusion process, such as in mold making.

[0151] In addition, regarding the insertion and positioning of the moxa stick, protrusions, bumps, or stop pins can also be used for the insertion and positioning of the moxa stick, without the need for additional moxa stick positioning structures such as the upper support plate 63.

[0152] from Figure 1 , Figure 2 and Figure 5As can be seen from the above, the upper cover plate 41 of the upper cover 3 and the lower cover plate 33 of the lower cover 2 are both spherical structures. Correspondingly, the lower surface of the upper cover plate 41 is an upward concave surface, and the upper surface of the lower cover plate 33 is an upward convex surface. Corresponding to the first detachable connection structure and the second detachable connection structure, the surface curvature of the upper bracket 6 or the lower bracket 2 that mates with the corresponding concave or convex surface is less than or equal to the curvature of the corresponding concave or convex surface. Since these two detachable connection structures adopt a center connection method, after the upper bracket 6 is assembled, for example, the upper bracket 6 will undergo elastic deformation or just match the lower surface of the upper cover plate 41, so that the detachable connection structure has a certain pre-tightening force and can press the upper filter cotton 5 more firmly.

[0153] Corresponding to the third detachable connection structure, the curvature of the surface of the upper bracket 6 or the lower bracket 2 that mates with the corresponding concave or convex surface is greater than or equal to the curvature of the corresponding concave or convex surface. Similarly, due to the adoption of the side connection method, under this condition, when, for example, the upper bracket 6 is assembled in place, the upper bracket 6 will also undergo elastic deformation or just match the lower surface of the upper cover plate 41, thereby making the friction between the single-sided buckle and the upper bracket 6 relatively large, the connection firmness relatively good, and at the same time, it can more reliably press the upper filter cotton 5.

[0154] Regarding the fitting method between the upper cover 4 and the lower cover 3, which mainly refers to the fitting method between the two main parts constituting the box body, there are three main methods, referred to as the first fitting method, the second fitting method, and the third fitting method. The first fitting method involves the upper cover 3 being mounted on the lower cover 3 via a side hinge. With the help of the side hinge, the upper cover 3 can be opened or closed. Furthermore, the upper cover 4 and the lower cover 3 have a latch on the side opposite to the side hinge; this is a common form and will not be elaborated upon here.

[0155] In the second fitting method, the upper cover 4 has a cylindrical upper shell 43, and the lower cover 3 has a cylindrical lower shell 35. The upper shell 43 and the lower shell 35 are nested and fitted with an interference fit. This fitting method is relatively simple, and both the upper cover 4 and the lower cover 3 form a bottomed barrel structure.

[0156] In the third mating configuration, the upper cover 4 has a cylindrical upper shell 43, and the lower cover has a cylindrical lower shell 35. The inner cylindrical surface of the upper shell 43 is a cylindrical surface, and the inner cylindrical surface of the lower shell 35 is a cylindrical surface. One of the cylindrical surfaces is an external thread, and the other cylindrical surface is an internal thread. The upper cover 4 and the lower cover 3 are connected based on the engagement of the internal and external threads.

[0157] The structural form of the lower cover plate 33 has been described in several places above. In addition to the aforementioned functions, user comfort has also been considered. Accordingly, the lower surface of the lower cover plate 33 is an upwardly concave curved surface; Figure 8The lower cover 32 is represented by a concave surface, and the lower air holes are distributed within the concave surface. Under these conditions, when the lower cover 3 is placed against the abdomen, for example, it feels relatively comfortable.

[0158] Furthermore, the concave surface has a raised texture, such as... Figure 8 The decorative texture 36 shown also provides some support, which is beneficial to the flow of the effective ingredients in moxibustion.
