Description

Technical Field

[0001] This utility model relates to the field of physiotherapy and health preservation, and in particular to an electronic moxibustion device. Background Technology

[0002] Existing electronic moxibustion devices typically place a thermometer inside the combustion chamber to measure the temperature of the smoke, thereby controlling the fan speed to regulate the temperature of the moxibustion device. As the moxa burns inside the combustion chamber, it produces a large amount of unfiltered black smoke and ash. This black smoke and ash adhere to the thermometer, and with long-term use, a thick layer of grease forms on the surface of the thermometer, making it dirty and causing inaccurate temperature readings or even damage to the thermometer. This can lead to inaccurate temperature control and the risk of burns to the user. Utility Model Content

[0003] In order to solve at least one of the above-mentioned technical problems, one objective of this utility model is to provide a thermometer that can remain relatively clean even after long-term use, thereby ensuring good temperature measurement accuracy and consistency.

[0004] The electronic moxibustion device of this utility model includes a housing, a moxa stick fixing component, a filter component, a fan, and a thermometer. The housing has a combustion chamber, a filter chamber, and an exhaust chamber. The moxa stick fixing component is used to install the moxa stick and is located in the combustion chamber. The filter component is located in the filter chamber, and the fan is located in the exhaust chamber. The side wall of the housing has a first air vent that can communicate with the outside at the position corresponding to the exhaust chamber. The thermometer is located in the air outlet channel between the fan and the first air vent. The fan is used to draw in the smoke generated by the burning moxa stick, so that the smoke enters the filter chamber, is filtered by the filter component, enters the exhaust chamber, flows through the thermometer, and is discharged from the first air vent. The thermometer is used to measure the temperature of the smoke and / or to measure the temperature of the outside air entering the exhaust chamber from the first air vent.

[0005] In this embodiment of the utility model, by placing the thermometer inside the exhaust chamber, compared to the prior art where it is placed inside the combustion chamber, it can effectively avoid the thermometer being contaminated by the ash of the incense and also avoid being contaminated by the unfiltered black smoke produced by the burning of the incense. This allows the surface of the thermometer to remain relatively clean, ensuring that the temperature measured after long-term use still has high accuracy and consistency.

[0006] The thermometer can be used solely to measure the temperature of the moxa smoke after it has passed through the filter. In this case, the thermometer detects the temperature of the relatively clean smoke that has been filtered and discharged. Alternatively, the thermometer can be used solely to measure the temperature of the outside air entering the exhaust chamber from the first vent. This allows the electronic moxibustion device to obtain ambient temperature data for intelligent control, improving user comfort under varying room temperatures. Furthermore, the thermometer can also perform two functions simultaneously: detecting both the temperature of the filtered moxa smoke and the temperature of the outside air entering the exhaust chamber from the first vent. For example, it can be used to detect the ambient temperature for one or a few seconds after the electronic moxibustion device is first activated, before smoke is generated, and then to detect the temperature of the moxa smoke. This multi-purpose thermometer makes the electronic moxibustion device more intelligent.

[0028] Although the present invention 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 also understood that this specification should be regarded as an exemplary description of the principles of the present invention and is not intended to limit the present invention to what is described herein.

[0029] Therefore, a feature pointed out in this specification is used to describe one feature of one embodiment of the present invention, and does not imply that every embodiment of the present invention must have the described feature. Furthermore, it should be noted that this specification describes many features. Although 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.

[0030] In the embodiments shown in the accompanying drawings, the directional indications (such as up, down, inside, outside, left, right, front, back, etc.) used to explain the structure and movement of the various components of this invention are relative rather than absolute. These descriptions are appropriate when these components are in the positions shown in the drawings. If the descriptions of the positions of these components change, these directional indications also change accordingly.

[0031] It should also be noted that when the connection between components is described as "fixed to" or "set on" another component, the component can be directly on the other component or there may be an intervening component. When a component is described as "connected" to another component, it can be directly connected to the other component or indirectly connected to the other component.

[0032] 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 the present invention 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 the present invention 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.

[0033] The preferred embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0034] In this utility model of electronic moxibustion device, the vertical relationships described below involving "above," "upper end," "upper side," etc., mainly refer to the vertical relationships along the height direction of the electronic moxibustion device, such as... Figure 2 The marked "up" and "down".

[0035] refer to Figures 1 to 8As shown, the electronic moxibustion device of this embodiment includes a housing 1, a moxa stick fixing component 2, a filter component 3, a fan 4, and a thermometer 5. The housing 1 is provided with a combustion chamber 100, a filter chamber 200, and an exhaust chamber 300. The moxa stick fixing component 2 is used to install moxa sticks, which include moxa wool containing mugwort leaves, moxa sticks, moxa cones, mixtures of moxa sticks and other Chinese medicines, etc., which are combustible materials with moxibustion effects. The moxa stick fixing component 2 is located in the combustion chamber 100, the filter component 3 is located in the filter chamber 200, and the fan 4 is located in the exhaust chamber 300. The side wall of the housing 1 is provided with a first air outlet 13 that can communicate with the outside at the position corresponding to the exhaust chamber 300. The thermometer 5 is located on the air outlet channel between the fan 4 and the first air outlet 13. The fan 4 includes an air inlet 41 and an air outlet 42. The air outlet channel between the fan 4 and the first air outlet 13 refers to the path through which the airflow passes between the air outlet 42 of the fan 4 and the first air outlet 13. The fan 4 is used to draw in the smoke produced by the burning moxa, which enters the filter chamber 200, is filtered by the filter element 3, enters the exhaust chamber 300, and flows through the thermometer 5 before being discharged from the first air outlet 13. The fan 4 is usually an exhaust fan 4, which facilitates the extraction and discharge of smoke from the electronic moxibustion device to the outside. The temperature of the electronic moxibustion device can be adjusted by the speed at which the exhaust fan 4 draws in the smoke, thus making it suitable for different user groups.

[0036] The moxibustion device fixing component 2 can be any form of fixing structure, including a fixing structure with a pin, a fixing component with multiple clamps, or a supporting net / support plate for supporting the moxibustion column.

[0037] The filter element 3 can be any material with filtration function, such as filter cotton, filter screen, or activated carbon, or a combination of multiple filter materials 33. It can also be an assembly consisting of a housing and filter materials 33, with the filter materials 33 housed within the housing. The filter materials 33 can be materials with filtration function, such as filter cotton, filter screen, or activated carbon. The filter cotton can include one or more of the following: synthetic fiber filter cotton, non-woven filter cotton, glass fiber filter cotton, and activated carbon filter cotton. Specifically, it can be as follows: Figure 3 As shown, the box body includes an upper box 31 and a lower box 32. The upper box 31 and the lower box 32 are interlocked to form a cavity for accommodating filter cotton. The filter cotton is a two-layer filter structure composed of synthetic fiber filter cotton and activated carbon filter cotton. The box body is provided with a flue gas inlet 311 and a flue gas outlet 312. The flue gas enters the box body through the flue gas inlet 311, is filtered by the filter cotton material 33, and is discharged through the flue gas outlet 312.

[0038] The thermometer is located inside the exhaust chamber, which, compared to existing technologies where it is located inside the combustion chamber, effectively prevents the thermometer from being contaminated by the ash of the incense and by the unfiltered black smoke produced by the burning of the incense. This keeps the surface of the thermometer relatively clean and ensures that the temperature measured after long-term use still has high accuracy and consistency.

[0039] The thermometer can be used solely to measure the temperature of the moxa smoke after it has passed through the filter. In this case, the thermometer detects the temperature of the relatively clean smoke that has been filtered and discharged. Alternatively, the thermometer can be used solely to measure the temperature of the outside air entering the exhaust chamber from the first vent. This allows the electronic moxibustion device to obtain ambient temperature data for intelligent control, improving user comfort under varying room temperatures. Furthermore, the thermometer can also perform two functions simultaneously: detecting both the temperature of the filtered moxa smoke and the temperature of the outside air entering the exhaust chamber from the first vent. For example, it can be used to detect the ambient temperature for one or a few seconds after the electronic moxibustion device is first activated, before smoke is generated, and then to detect the temperature of the moxa smoke. This multi-purpose thermometer makes the electronic moxibustion device more intelligent.

[0040] Along the height direction of the housing 1, the filter chamber 200 is located above the combustion chamber 100, the exhaust chamber 300 is located above the filter chamber 200, the air inlet 41 of the fan 4 faces the filter chamber 200, the air outlet 42 faces the first air outlet 13, and the temperature sensor 5 is located between the air outlet 42 and the first air outlet 13.

[0041] The temperature sensor is positioned between the air outlet and the first air inlet, with the air outlet facing the first air inlet. This allows the flue gas blown out of the air outlet by the fan to directly reach the temperature sensor for measurement, avoiding temperature loss and making the measurement more accurate. After passing through the temperature sensor, the flue gas is discharged directly from the air outlet facing the flue gas direction. This ensures a continuous and smooth flow of flue gas from the air outlet to the first air inlet, resulting in faster smoke extraction and preventing the smoke extraction speed from being reduced due to obstacles or bends. Figure 2 and Figure 4 As shown, the air outlet 42 of the fan 4 faces the first air outlet 13, and the air outlet 42 and the first air outlet 13 are arranged in a straight line directly opposite each other.

[0042] The exhaust chamber 300 is equipped with a mounting plate 93, which has a clearance hole 931. The mounting plate 93 also has a retaining plate for limiting the movement of the fan 4. The fan 4 is located inside the retaining plate, with its air inlet 41 directly facing the clearance hole 931, allowing the flue gas flowing through the filter chamber 200 to enter the exhaust chamber 300 through the air inlet 41. By limiting the fan with the retaining plate, the fan can be effectively fixed. Furthermore, the retaining plate does not extend to the outside of the air outlet 42, meaning there is no retaining plate obstructing the airflow direction of the outlet. This allows the airflow from the outlet to blow directly towards the first air vent, resulting in smoother exhaust.

[0043] like Figure 4As shown, the enclosure includes a first plate 941, a second plate 942, and a third plate 943 located on the outer sides of three sides of the fan 4. The side of the fan 4 facing the first air outlet 13 has no plate, but a very low rib 95 can be provided to reinforce the fan 4. The second plate 942 is located between the first plate 941 and the third plate 943, which are positioned opposite each other. One end of the first plate 941 and one end of the third plate 943 are respectively connected to the inner wall of the exhaust cavity 300. An opening 944 is provided between the other ends of the second plate 942 and the first plate 941, or between the other ends of the second plate 942 and the third plate 943. During the assembly and disassembly of the fan 4, when the enclosure is compressed, the opening 944 provides deformation space for the three plates, reducing the risk of damage caused by mutual compression between the second and first plates, or between the second and third plates.

[0044] The housing 1 also includes an electrical assembly cavity 400, which houses a circuit board 10 and a battery 20. The electrical assembly cavity 400 is adjacent to the exhaust cavity 300 and separated from it by a partition 7. The partition 7 has a through hole 71 through which a thermometer 5 passes. Adhesive can be applied to the end of the thermometer 5 facing the electrical assembly cavity 400 to fix it to the partition 7. The lower end of the thermometer 5 extends into the exhaust cavity 300 to measure the temperature of the flue gas or the outside air entering the exhaust cavity 300 from the first air inlet. The thermometer 5 is electrically connected to the circuit board 10 via a wire 51. By separating the electrical assembly cavity from the exhaust cavity with the partition, the high-temperature flue gas discharged from the exhaust cavity can be prevented from adversely affecting the electrical components inside the electrical assembly cavity, such as the circuit board and its electronic components and batteries. By inserting the thermometer through the partition, it is easy to fix the thermometer on the partition, and after the thermometer is fixed, it can also be inserted into the exhaust cavity to facilitate the measurement of the flue gas temperature.

[0045] The battery 20 is located on the separator 7, the temperature sensor 5 is located on the outside of the battery 20, the circuit board 10 is located above the battery 20, and a flexible component 30 is provided between the battery 20 and the circuit board 10. The flexible component 30 can be made of materials with cushioning properties such as soft rubber, foam, or cotton. The flexible component 30 usually forms a sheet structure and is attached to the upper surface of the battery 20. The electrical wiring 51 is clamped between the flexible component 30 and the battery 20.

[0046] By incorporating a flexible component between the battery and the circuit board, hard contact between the circuit board and the battery during transportation and other processes can be effectively avoided, protecting the circuit board from damage. Furthermore, the electrical wiring clip for the temperature sensor is positioned between the flexible component and the battery. This allows the wiring to be secured to the battery surface while simultaneously fixing the flexible component in place, ensuring an orderly arrangement of the wiring, preventing tangled wires from affecting other components, and facilitating the connection of the wiring to the ports on the edge of the circuit board.

[0047] The housing 1 includes a detachably connected upper housing 11 and a lower housing 12. A first connecting body 8 and a second connecting body 9 are provided within the housing 1. A first cavity 81 is formed in the upper part of the first connecting body 8, and a filter element 3 is placed within the first cavity 81. An object fixing member 2 is provided on the first connecting body 8 and extends away from the filter cavity 200. The lower part of the first connecting body 8 forms part of the combustion chamber 100. A mounting plate 93 is provided within the second connecting body 9, dividing the second connecting body 9 into an upper exhaust cavity 300 and a lower second cavity 91. The first connecting body 8 is detachably connected to the second connecting body 9. When the first connecting body 8 is installed on the second connecting body 9, the upper part of the first connecting body 8 extends into the second cavity 91. The first cavity 81 and the second cavity 91 together limit the position of the filter element 3. The first cavity 81 forms the filter cavity 200, or the first cavity 81 and the second cavity 91 together constitute the filter cavity 200. The side wall of the second connector 9 is provided with a second air outlet 97 that connects the exhaust chamber 300 to the first air outlet 13, such as Figure 2 As shown, the side wall of the second connecting body 9 is adjacent to or in contact with the inner wall of the housing 1. The second air vent 97 and the first air vent 13 are in the same position and both have multiple air holes. The air holes of the first air vent 13 and the air holes of the second air vent 97 are connected one-to-one.

[0048] When the filter element 3 is substantially completely contained in the first cavity 81, the first cavity 81 can form a complete filter cavity 200 on its own. In this case, the top wall of the second cavity 91 and the side wall of the filter cavity 200 together limit the filter element 3. When a part of the filter element 3 is contained in the first cavity 81 and another part is contained in the second cavity 91, the first cavity 81 and the second cavity 91 together enclose and form the filter cavity 200.

[0049] The filter element is located in the filter cavity at the top of the first connector. The first connector can be detached from the second connector for easy replacement of the filter element. The filter element is limited by the first cavity of the first connector and the second cavity of the second connector, eliminating the need for additional locking structures such as clips. When the first connector 8 is detached from the second connector 9, the filter element 3 can be directly removed, making it easier, more convenient, and faster to assemble and disassemble the filter element without having to overcome the locking force. This design also simplifies the structure of the first connector.

[0050] Specifically, such as Figures 4-6As shown, both the first connecting body 8 and the second connecting body 9 form a cylindrical structure. The detachable connection structure of the first connecting body 8 and the second connecting body 9 is as follows: the outer surface of the upper part of the first connecting body 8 has a first protruding buckle 84 protruding outwards; the second cavity 91 of the second connecting body 9 has two or more first slots 96. Each first slot 96 includes a slot opening 961, a groove 962 connected to the slot opening 961 and extending circumferentially along the cavity wall of the second cavity 91, and a locking rib 963 at the end of the groove 962. After the first protruding buckle 84 of the first connecting body 8 is inserted from the slot opening 961, rotating the first connecting body 8 causes the first protruding buckle 84 to pass over the locking rib 963 and lock it at the end of the groove 962. The locking rib 963 prevents the first connecting body 8 from loosening and causing the first protruding buckle to dislodge from the first slot. When disassembly is required, forcefully rotate the first connecting body 8 in the opposite direction so that the first protruding buckle 84 passes over the locking rib 963 and dislodges from the slot opening 961. Of course, the positions of the first protrusion 84 and the first slot 96 can be interchanged. The first protrusion 84 can be set on the second connector 9, and the first slot 96 can be set on the first connector 8.

[0051] The disassembly and connection structure of the upper shell 11 and the lower shell 12 is basically the same as the connection structure of the first connector 8 and the second connector 9. Both are connected by a convex buckle and a slot, and are engaged and disassembled by rotation. For example... Figure 1 As shown, the upper shell 11 is provided with a second slot 111, and the lower shell 12 is provided with a second protrusion 124. By rotating the upper shell 11 or the lower shell 12, the second protrusion and the second slot can be moved from the interlocked state to the separated state, and the shell 1 can be opened.

[0052] A sealing element 40 is provided between the top wall of the second cavity 91 and the edge of the filter element 3, or between the top wall of the second cavity 91 and the cavity wall of the filter cavity 200. The top wall of the second cavity 91 is the lower surface of the mounting plate 93. For ease of installation, the sealing element 40 can be pasted or snapped into the lower surface of the mounting plate 93.

[0053] The sealing element is used to seal the gap between the edge of the filter element and the second connector, or to seal the assembly gap between the first connector and the second connector. Both sealing methods can prevent flue gas from flowing out from the gap between the first connector and the second connector. This allows almost all the flue gas to enter the fan and then be discharged from the first air outlet, making the flue gas flow orderly and preventing the flue gas from running around and causing poor exhaust.

[0054] like Figure 3As shown, the filter element 3 has a convex edge 313, which is an outwardly extending convex edge from the upper end of the upper box 31. The convex edge 313 is supported on the opening of the first cavity 81. The sealing element 40 is disposed on the top wall of the second cavity 91. The top wall of the second cavity 91 is provided with annular limiting ribs 92 or multiple limiting ribs 92 spaced apart for limiting the sealing element 40. The sealing element 40 is located between the cavity wall of the second cavity 91 and the limiting ribs 92. When the first connecting body 8 is assembled on the second connecting body 9, the convex edge 313 abuts against the sealing element 40. By providing an convex edge on the filter element's housing, the sealing element can be pressed tightly by the convex edge, achieving a better sealing effect and allowing the flue gas to enter the exhaust chamber and be discharged.

[0055] In addition, two opposing handle grooves 85 can be formed on the side wall of the filter chamber 200, which makes it easier to pry out or pinch the outer protruding edge 313 to remove the filter element 3.

[0056] In some preferred embodiments, the moxa stick fixing member 2 has a bracket 21 and a clamping part 22 provided on the bracket 21. The bracket 21 has an opening 211 and a hollow part 212 for the smoke generated by the burning moxa stick to pass through. The hollow part 212 facilitates the smoke after the burning moxa stick to enter the filter chamber 200 for filtration through the bracket 21. The moxa stick fixing part 2 is made of metal. The clamping part 22 extends away from the first cavity 81. The clamping part 22 includes multiple clamps 221. The clamps 221 are formed by bending downward from the bracket 21. The moxa stick is installed in the multiple clamps 221. The clamps 221 are provided with springs 222 that push against the moxa stick. The end of the spring 222 that contacts the moxa stick is provided with a metal sheet 223. During the burning process of the moxa stick, after the moxa stick at the front end burns out, the spring 222 will push the moxa stick towards the skin, so that the distance between the burning surface and the skin remains basically unchanged. This makes the temperature more stable during the burning process. The contact between the metal sheet 223 and the moxa stick makes the moxa stick move smoothly as a whole.

[0057] The inner wall of the first connector 8 is provided with an inwardly protruding edge 82 and a fastener 83. The lower end of the filter element 3 is supported on the edge 82. The fastener 83 is located on the downward side of the edge 82. The fastener 83 and the edge 82 form a gap in the vertical direction. The bracket 21 enters the gap after aligning with the fastener 83 through the opening 211, and is fixed after rotation.

[0058] The upper side of the rim forms the first cavity for placing the filter element, while the filter element fixing component is located on the lower side of the rim, which forms part of the combustion chamber. The bracket is installed and fixed in the gap between the fastener and the rim by rotation and fastening, making assembly simple and convenient.

[0059] The lower shell 12 includes an outer cylinder 121, an inner cylinder 122, a heat insulation ring 123, and a decorative ring 125. The inner cylinder 122 and the heat insulation ring 123 are both located inside the outer cylinder 121, with the heat insulation ring 123 sandwiched between the lower end of the inner cylinder and the lower end of the outer cylinder 121. There is a gap between the outer wall of the heat insulation ring 123 and the inner wall of the outer cylinder 121. A second protrusion 124 is located at the upper part of the inner cylinder 122, and the decorative ring 125 is located at the upper part of the inner cylinder 122 and below the second protrusion 124, allowing the second protrusion to be exposed for easy connection with the second slot of the upper shell. By providing a heat insulation ring on the inner side of the outer cylinder and spacing it from the inner wall of the outer cylinder, the heat generated by the burning moxa is not easily conducted to the outer cylinder, preventing the outer cylinder from overheating and scalding the user. The heat insulation ring is sandwiched between the lower end of the inner cylinder and the lower end of the outer cylinder, facilitating the assembly of the heat insulation ring.

[0060] like Figure 2 and Figure 8 As shown, heat insulation rings are typically made of metal, most commonly stainless steel, and are usually formed as a ring-shaped stainless steel sheet with multiple tiny holes. The metal heat insulation ring can quickly absorb heat, reducing the heat transferred to the outer casing, lowering the casing temperature, and reducing the risk of burns.

[0061] The lower end of the lower shell 12 is also provided with a base 14, which has a moxibustion port 141 facing the skin. The moxibustion port is usually provided with an ash-collecting mesh 50 to prevent the ash from burning the moxa from falling onto the skin and burning the user. An elastic buckle 142 is provided on the outer periphery of the moxibustion port 141 on the base 14. The inner wall of the outer cylinder 121 has an inwardly protruding step 1211, which is formed as a retaining edge or has a retaining groove. The elastic buckle 142 extends into the interior of the outer cylinder 121 and engages with the retaining edge or retaining groove. A first slot 15 is formed between the inner wall of the outer cylinder 121 and the elastic buckle 142. A second slot 1221 is provided at the lower end of the side wall of the inner cylinder 122. The upper end of the heat insulation ring 123 is inserted into the second slot 1221, and the lower end of the heat insulation ring 123 is inserted into the first slot 15.

[0062] A first slot for holding the heat insulation ring is formed between the elastic buckle and the inner wall of the outer cylinder, and a second slot for holding the heat insulation ring is formed at the lower end of the inner cylinder. This allows the heat insulation ring to be assembled by insertion, resulting in a simple and convenient assembly structure. In addition, the inner side of the second slot facing the combustion chamber has a downward-facing extension wall to better limit and guide the heat insulation ring.

[0063] The upper shell 11 is connected to the first connecting body 8, and the object fixing part 2 is installed on the first connecting body 8. The inner wall of the inner cylinder 122 is provided with an inwardly protruding boss 1222. When the upper shell 11 and the lower shell 12 are disassembled, the first connecting body 8 is separated from the lower shell 12. When the upper shell 11 and the lower shell 12 are assembled and connected, the lower end of the first connecting body 8 is close to or in contact with the boss 1222. The first connecting body 8, the heat insulation ring 123 and the inner cylinder 122 together form the combustion chamber 100.

[0064] By setting an inwardly protruding boss on the inner cylinder to cooperate with the first connector to form part of the combustion chamber sidewall, a smaller combustion chamber is formed by the first connector, the heat insulation ring and the inner cylinder together. This allows the heat and medicinal properties generated by moxibustion to be more concentrated and applied to the skin of the human body through the moxibustion opening, resulting in a better moxibustion effect.

[0065] The electronic moxibustion device has a power switch and a speed control button on the top. When performing moxibustion, the user removes the lower shell 12 from the upper shell 11, inserts the moxa into the multiple clamps 221, ignites the moxa, and presses the power switch. The fan 4 and thermometer 5 then operate. The fan 4 rotates to draw in the smoke generated by the burning moxa. The smoke enters the filter 3 from the combustion chamber 100, is filtered, and then enters through the fan 4's air inlet 41 and exits through the fan 4's air outlet 42. The heat and medicinal effects generated by the burning moxa act on the skin and corresponding acupoints through the moxibustion port 141, achieving a therapeutic effect. During moxibustion, the fan 4's suction also accelerates the flow of outside air through the vent 16 and the small holes on the heat insulation ring 123 into the combustion chamber 100, providing oxygen to the moxa and preventing it from extinguishing. If the user feels it is not hot enough during moxibustion, they can adjust the speed using the speed control button. Generally, the higher the speed, the greater the fan 4's rotation speed, resulting in a higher moxibustion temperature. If the user feels it is too hot, they can lower the speed.
