Description

Technical Field

[0001] This invention relates to the field of physiotherapy device technology, specifically to a rotary temperature-controlled smokeless moxibustion device. Background Technology

[0002] Moxibustion, as a traditional external treatment method in Chinese medicine, has now been widely integrated into various modern physiotherapy devices. Currently, the most common moxibustion physiotherapy devices on the market are mainly divided into two categories: one is devices that use traditional open flame to burn moxa sticks or moxa wool, and the other is new physiotherapy devices that use smokeless heat sources such as electric heating or chemical self-heating.

[0003] The first type of open-flame therapy device inevitably produces smoke during its core combustion process, resulting in a smoky environment that causes breathing discomfort for users and poses a fire hazard. More importantly, the temperature of its heat source directly depends on the combustion state, which is a violent and delayed chemical reaction process. This makes temperature control extremely difficult, and users can only try to control the temperature by roughly adjusting the ventilation or the height of the moxibustion. The response is slow and the precision is low, which can easily cause burns or insufficient heat penetration at the moxibustion site. It is difficult to balance efficacy and safety.

[0004] The second type of smokeless physiotherapy device, such as one that uses an electric heating wire as a heat source, solves the smoke problem, but its temperature control mechanism still has significant defects. These devices usually employ a single temperature control strategy, such as adjusting the output power of the electric heating wire or adjusting the distance between the heat source and the skin through mechanical structures. However, a single adjustment method has the following inherent limitations:

[0005] Adjusting only the output power of the heating wire results in a large thermal inertia in the change of the heat source output power, and the response is not fast enough. Adjusting only the heat transfer distance makes it difficult to directly intervene in the heating intensity of the heat source itself, and the temperature control accuracy and range are limited.

[0006] Therefore, existing smokeless physiotherapy devices generally suffer from the core problems of slow temperature regulation response and insufficient precise and stable temperature control. As a result, while pursuing safety and smokelessness, they often sacrifice the precision and real-time controllability of heat penetration necessary for moxibustion, affecting the physiotherapy effect and user experience.

[0007] In summary, there is a lack of existing technologies for a moxibustion therapy device that can completely eliminate smoke and achieve a combination of rapid response and precise control. Summary of the Invention

[0008] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a rotary temperature-controlled smokeless moxibustion device, which can effectively solve the problems existing in the prior art.

[0009] To achieve the above objectives, the present invention provides the following technical solution:

[0010] This invention provides a rotary temperature-controlled smokeless moxibustion device, including a moxibustion cover and a moxibustion cylinder. The moxibustion cylinder is used to accommodate a self-heating pack. A placement groove for accommodating moxibustion materials is provided at the bottom of the moxibustion cylinder. A heat-conducting plate for transferring heat from the self-heating pack to the moxibustion materials is provided between the placement groove and the self-heating pack at the bottom of the moxibustion cylinder. The moxibustion cover and the moxibustion cylinder are respectively provided with mutually cooperating ventilation structures. The ventilation structures are used to regulate the gas flow rate through the self-heating pack per unit time. The moxibustion cylinder is provided with a support mechanism that can move along its axial direction to support the self-heating pack. A radial adjustment mechanism is provided above the support mechanism for applying radial force to the self-heating pack to change its compaction state. When the moxibustion cover is rotated, the compaction state of the self-heating pack and its heat transfer distance with the moxibustion site are adjusted by the radial adjustment mechanism.

[0011] Furthermore, the ventilation structure includes vents on the outer wall of the moxibustion cylinder for air inflow, and vent grooves on the outer wall of the moxibustion cover that cooperate with the vents. When the moxibustion cover is rotated, the overlapping area of ​​the vent grooves and vents changes.

[0012] Furthermore, the support mechanism includes a support ring disposed on the heat-conducting plate, a heat-conducting gap is provided between the support ring and the heat-conducting plate, a slider is disposed on the heat-conducting plate, the top of the slider abuts against the bottom of the support ring, and an adjustment slope is provided on the top of the slider.

[0013] Furthermore, the radial adjustment mechanism includes a connecting plate disposed inside the moxibustion cover, and a movable pressure plate that can be elastically pressed down at the bottom of the connecting plate. When the moxibustion cover is combined with the moxibustion cylinder, the movable pressure plate presses against the top of the self-heating pack. A vertical block is disposed at the bottom of the movable pressure plate, and a clamping block for holding the self-heating pack is disposed on the inner wall of the moxibustion cylinder. One side of the clamping block is connected to the inner wall of the moxibustion cylinder through an elastic element, and the bottom of the clamping block is connected to a slider through a connecting rod. An adjustment mechanism for driving the clamping block to move radially when the moxibustion cover is rotated is disposed between the vertical block and the clamping block.

[0014] Furthermore, a guide rod is provided at the top of the movable pressure plate to limit the movable pressure plate. The guide rod passes through the connecting plate and can slide up and down relative to it. A rotating plate is rotatably provided at the bottom of the movable pressure plate. The bottom surface of the rotating plate abuts against the top surface of the self-heating pack. When the moxibustion cover is rotated, the rotating plate can rotate relative to the movable pressure plate, thereby blocking the transmission of rotational torque to the self-heating pack.

[0015] Furthermore, when the moxibustion cover is rotated, the adjustment mechanism drives the locking block to move radially along the moxibustion cylinder. The locking block drives the slider to move along the heat-conducting plate via a connecting rod. When the slider moves, the adjustment slope at the top of the slider interacts with the bottom of the support ring, driving the support ring to rise and fall relative to the heat-conducting plate, thereby changing the size of the heat-conducting gap.

[0016] Furthermore, the two ends of the connecting rod are hinged to the locking block and the slider respectively, and a moving block is provided at the bottom of the slider. A moving groove for the moving block to slide is provided at the corresponding position on the heat-conducting plate.

[0017] Furthermore, the adjustment mechanism includes a spherical block disposed on the side of the locking block near the inner wall of the moxibustion cylinder, a guide vertical groove that cooperates with the spherical block disposed on the side of the vertical block away from the inner wall of the moxibustion cylinder, and an adjustment groove extending along the rotation direction of the moxibustion cover on one side of the guide vertical groove, the thickness of the inner wall of the adjustment groove continuously changing along its extension direction.

[0018] Furthermore, when the moxibustion cover is rotated, the spherical block enters the adjustment groove from the end of the guide vertical groove. The changing inner wall can continuously squeeze or release the spherical block, thereby driving the card block to move radially.

[0019] Furthermore, the bottom of the locking block is rotatably connected to the inner wall of the moxibustion cylinder via a hinge shaft. The locking block can rotate around the hinge shaft to achieve radial movement. A movable gap is reserved between the side of the locking block away from the center of the moxibustion cylinder and the inner wall of the moxibustion cylinder. The movable gap is used to accommodate the insertion of the vertical block when the moxibustion cover is combined with the moxibustion cylinder, and to provide movement space for the cooperation between the vertical block and the locking block.

[0020] The technical solution provided by this invention has the following advantages compared with the prior art:

[0021] This invention, through a single operation of rotating the moxibustion cover, can simultaneously drive the radial adjustment mechanism, the support mechanism, and the ventilation structure, thereby achieving integrated and coordinated control of the self-heating pack's compaction state, heat transfer distance, and ventilation flow. It can directly intervene quickly and precisely from two physical dimensions: the intensity of the heat source response and the heat transfer path, thus effectively solving the problems of slow response and insufficient precision in temperature control of existing smokeless moxibustion therapy devices.

[0039] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0040] The present invention will be further described below with reference to embodiments.

[0041] Example 1

[0042] Reference Figures 1 to 7The first embodiment of the present invention provides a rotary temperature-controlled smokeless moxibustion device, including a moxibustion cover 1 and a moxibustion cylinder 11, wherein the moxibustion cylinder 11 is used to contain a self-heating pack.

[0043] The self-heating pack is a common chemical heating element in the prior art. It usually contains a mixture of iron powder, activated carbon, salt, water and other substances. When the self-heating pack is exposed to air, the iron powder in it undergoes an oxidation-reduction reaction. This process is an exothermic reaction, which can continuously generate heat. This is a well-known technology in the field. Its specific composition ratio is not the focus of this invention and will not be described in detail here.

[0044] The bottom of the moxibustion cylinder 11 is provided with a placement groove 12 for holding moxibustion materials, such as ginger slices, garlic slices, and Chinese herbal cakes. The heat generated by the self-heating pack is indirectly received through the heat-conducting plate 13, thereby achieving the therapeutic effect of traditional indirect moxibustion. It should be noted that this device also supports another way of use, that is, mugwort powder or Chinese herbal powder can be directly filled into the pre-set cavity of the self-heating pack or mixed with its reactants. In this case, the self-heating pack has the dual functions of heating and drug volatilization. When ginger slices or other items are placed in the placement groove 12, the comprehensive moxibustion effect produced by the penetration of their juice can be utilized at the same time. This provides users with flexible and diverse physiotherapy options.

[0045] The specific usage method is as follows: open the sealed bag of the self-heating pack, take out the self-heating pack, roll it up or put it into the moxibustion tube 11 according to its shape, put on the moxibustion cover 1 and screw it on, then put the attached adhesive on the base of the moxibustion tube 11, peel off the anti-adhesive paper, and apply the entire device to the skin area that needs moxibustion treatment. This operation process is simple and can be completed independently by the user.

[0046] At the bottom of the moxibustion cylinder 11, between the placement groove 12 and the self-heating pack, there is a heat-conducting plate 13 for transferring heat from the self-heating pack to the moxibustion material. The heat-conducting plate 13 is preferably made of a metal material with good thermal conductivity, such as aluminum, copper, or aluminum alloy. Multiple through holes can be provided on the heat-conducting plate 13. These through holes help to distribute heat more evenly inside the plate and may allow a small amount of moisture or medicinal vapor to pass through. These are all conventional settings in the prior art and will not be described in detail here.

[0047] The moxibustion cover 1 and the moxibustion tube 11 are respectively provided with mutually cooperating ventilation structures 2. The ventilation structures 2 are used to regulate the gas flow rate through the self-heating pack per unit time, thereby controlling its oxidation reaction rate.

[0048] Specifically, the ventilation structure 2 includes multiple circular vent holes 21 on the outer wall of the moxibustion cylinder 11, and an elongated vent groove 22 on the outer wall of the moxibustion cover 1 corresponding to the vent holes 21. When the moxibustion cover 1 is rotated, the overlapping area between the vent groove 22 and the lower vent holes 21 changes continuously. The larger the overlapping area, the more airflow enters the device per unit time, the more intense the oxidation reaction of the self-heating pack, and the higher the heat generation power. Conversely, the airflow decreases, the reaction is inhibited, and the heat generation decreases. This structure achieves basic control of the heat source intensity.

[0049] Above the support mechanism 3 is a radial adjustment mechanism 4 for applying radial force to the self-heating pack to change its compaction state. When the moxibustion cover 1 is rotated, the compaction state of the self-heating pack and its heat transfer distance with the moxibustion site can be adjusted in a coordinated manner through the radial adjustment mechanism 4.

[0050] Specifically, the radial adjustment mechanism 4 includes a connecting plate 41 disposed inside the moxibustion cover 1, and a movable pressure plate 42 that can be elastically pressed down at the bottom of the connecting plate 41. When the moxibustion cover 1 is combined with the moxibustion cylinder 11, the movable pressure plate 42 is pressed against the top of the self-heating pack under elastic action, which plays an initial limiting role and prevents it from shaking easily. A guide rod 45 is disposed at the top of the movable pressure plate 42. The guide rod 45 passes through the hole on the connecting plate 41 and can slide up and down relative to it, thereby restricting the movable pressure plate 42 to move only in the vertical direction and preventing it from tilting.

[0051] A spring connects the movable pressure plate 42 and the connecting plate 41. The spring provides a continuous elastic preload, ensuring that the movable pressure plate 42 can always be adaptively pressed against the surface of the self-heating pack. Even if the thickness of the self-heating pack is slightly different or the reaction volume changes during use, it can still maintain contact. At the same time, under the action of the movable pressure plate 42, the self-heating pack will not separate from the moxibustion material when the moxibustion device is inverted during use, which greatly enriches the application scenarios of the moxibustion device.

[0052] A rotating plate 46 is rotatably mounted on the bottom of the movable pressure plate 42 via a rotating shaft or bearing. The bottom surface of the rotating plate 46 abuts against the top surface of the self-heating pack. When the moxibustion cover 1 is rotated, the rotating plate 46 can rotate freely relative to the movable pressure plate 42. It can effectively block the transmission of the torsional torque generated by the rotation of the moxibustion cover 1 to the self-heating pack, thereby ensuring that the self-heating pack will not rotate with the moxibustion cover 1 inside the moxibustion cylinder 11, thus maintaining the stability of the heat source position.

[0053] The bottom of the locking block 44 is rotatably connected to the inner wall of the moxibustion cylinder 11 via a hinge shaft, allowing the locking block 44 to swing around the hinge shaft, thereby achieving radial inward clamping or outward releasing movement. A movable gap is reserved between the side of the locking block 44 away from the center of the moxibustion cylinder 11 and the inner wall of the moxibustion cylinder 11. This movable gap is used to accommodate the insertion of the vertical block 43 when the moxibustion cover 1 is combined with the moxibustion cylinder 11, and to provide the necessary space for the subsequent relative movement between the vertical block 43 and the locking block 44, avoiding interference.

[0054] In this embodiment, multiple locking blocks 44 are provided, and their number can be determined according to actual needs. As a preferred embodiment, three locking blocks 44 are provided, and the three locking blocks 44 are evenly distributed circumferentially inside the moxibustion tube 11. The multiple locking blocks 44 work together to apply a balanced restraining force to the self-heating pack from multiple directions, ensuring its stability.

[0055] It is important to note that the clamping or holding of the self-heating pack by the clamping block 44 does not completely lock it in place. The inner side of the clamping block 44 may be designed with anti-slip textures or flexible pads to increase friction, but it mainly provides radial constraint force to prevent the self-heating pack from moving or tipping in the horizontal direction. It also changes the radial compaction by applying pressure to the side wall of the self-heating pack. This clamping does not prevent the self-heating pack from rising and falling together with the support mechanism 3 in the vertical direction. In fact, the elastic design of the movable pressure plate 42 allows it to float up and down with the rise and fall of the self-heating pack. During the subsequent process of the support ring 31 lifting the self-heating pack, the static friction force generated by the clamping block 44 through increasing the radial clamping force is sufficient to prevent the self-heating pack from sliding down in an inclined state due to gravity or inertia, while not hindering it from being pushed upward.

[0056] An adjustment mechanism 5 is provided between the vertical block 43 and the locking block 44 for driving the locking block 44 to move radially when the moxibustion cover 1 is rotated. The adjustment mechanism 5 includes a spherical block 51 disposed on the side of the locking block 44 near the inner wall of the moxibustion cylinder 11, and a mating structure disposed on the vertical block 43. The mating structure includes a guide vertical groove 52 and an adjustment groove 53. The guide vertical groove 52 extends axially and is used to guide the spherical block 51 into it when the moxibustion cover 1 and the moxibustion cylinder 11 are initially joined, so as to achieve rapid radial alignment and initial connection and ensure convenient installation. The adjustment groove 53 extends from the bottom end or one side of the guide vertical groove 52 along the circumferential rotation direction of the moxibustion cover 1. The special feature of the adjustment groove 53 is that the thickness of its inner wall is continuously varied along its extension direction.

[0057] The working principle of the adjusting groove 53 is as follows: when the moxibustion cover 1 is combined with the moxibustion cylinder 11, the spherical block 51 is located in the guide vertical groove 52. At this time, when the moxibustion cover 1 is rotated, the vertical block 43 rotates accordingly, and the spherical block 51 enters the adjusting groove 53 connected to it from the guide vertical groove 52. Since the thickness of the inner wall of the adjusting groove 53 changes continuously, when the spherical block 51 slides in the adjusting groove 53, the changing inner wall contour will exert a continuous squeezing or releasing effect on the spherical block 51. This squeezing or releasing effect is transmitted to the locking block 44 through the spherical block 51, and is converted into a torque that drives the locking block 44 to swing around its hinge axis, thereby realizing the radial movement of the locking block 44. Rotating the moxibustion cover 1 clockwise and counterclockwise can drive the locking block 44 to tighten or loosen radially.

[0058] It should be further explained that when the clamp 44 tightens around the self-heating pack, the mechanical pressure reduces the pack's volume and internal porosity, decreasing the surface area of ​​the reactants in contact with air. This may also make the internal structure denser, hindering oxygen penetration and thus significantly inhibiting the oxidation reaction rate physically, achieving rapid cooling. Conversely, when the clamp 44 is released, the self-heating pack regains its fluffiness due to its own elasticity or the expansion of its internal materials, increasing porosity, air contact area, and permeability, accelerating the reaction rate and raising the temperature.

[0059] The aforementioned mechanical compaction temperature control method has an extremely rapid response. In addition, the process of adjusting the tightness of the locking block 44 by rotating the moxibustion cover 1 is synchronized and coordinated with the process of adjusting the opening of the vent 21. When heating is required, rotating the moxibustion cover 1 counterclockwise loosens the locking block 44 to promote the reaction, while simultaneously increasing the opening of the vent 21 to increase oxygen supply. The two work together to rapidly raise the temperature. When cooling is required, rotating the moxibustion cover 1 clockwise tightens the locking block 44 to suppress the reaction, while simultaneously decreasing the opening of the vent 21 to reduce oxygen supply. This dual inhibition achieves rapid and safe cooling. For example, when the moxibustion cover 1 is rotated to the point where the vent 21 is completely misaligned, i.e., at its minimum opening, the locking block 44 is usually also at its tightest state, at which point heat generation is suppressed to the maximum extent.

[0060] To verify the technical effectiveness of the aforementioned linkage temperature control mechanism compared to traditional single temperature control methods, comparative performance tests were conducted. In the tests, the device of the present invention was compared with Comparative Example A and Comparative Example B, where Comparative Example A is a device that can only adjust ventilation, and Comparative Example B is a device that can only adjust the distance to the heat source. The results are shown in the table below:

[0061]

[0062] As can be seen from the data in the table above, the embodiments of the present invention are significantly better than the two single temperature control methods in terms of rapid heating and cooling response speed and constant temperature control accuracy. In particular, the rapid cooling time is only 40% of that of comparative example A. This directly proves that it is difficult to achieve rapid cooling by simply reducing ventilation. The present invention directly suppresses the reaction through the clamping mechanism and, combined with the heat transfer distance adjustment, achieves a synergistic rapid cooling effect.

[0063] In summary, this invention achieves dual synchronous regulation of oxygen supply control and compaction control of the physical state of the reactants in the self-heating package reaction environment through the linkage design of the ventilation structure 2 and the radial adjustment mechanism 4. This is more direct and efficient than single airflow control. In particular, the compaction control can instantly change the contact conditions of the reactants, giving the device a rapid temperature regulation capability. At the same time, the mechanical linkage design ensures the simplicity and synchronization of operation.

[0064] Example 2

[0065] Reference Figures 8 to 10 This is the second embodiment of the present invention, which is based on embodiment 1 and further describes in detail the support mechanism 3 provided inside the moxibustion tube 11.

[0066] The support mechanism 3 can move along its axial direction to support the self-heating pack. Specifically, the support mechanism 3 includes a support ring 31 disposed on the heat-conducting plate 13. The support ring 31 is located above the central area of ​​the heat-conducting plate 13, and a certain gap is maintained between the two, namely the heat conduction gap.

[0067] The self-heating pack is placed on the support ring 31. Part of the heat it generates is directly applied to the upper or surrounding area through thermal radiation and convection, while the other part is conducted downward through the support ring 31 to the heat-conducting plate 13, and then evenly transferred to the moxibustion material in the placement groove 12 through the heat-conducting plate 13. The existence of the heat conduction gap allows the support ring 31 to have room for lifting and lowering, and its size change itself becomes a variable for adjusting thermal resistance.

[0068] On the heat-conducting plate 13, a slider 32 is arranged around the support ring 31. The top of the slider 32 abuts against the bottom of the support ring 31. The key point is that the top of the slider 32 is constructed with an adjustment slope 33, and the bottom of the support ring 31 has a corresponding inclined surface or plane.

[0069] Its working process and principle are as follows:

[0070] When the rotating moxibustion cover 1 drives the locking block 44 to move radially, the locking block 44 drives the slider 32 connected to it to slide radially on the heat-conducting plate 13 via the connecting rod 47. Since the top of the slider 32 is an inclined surface, when the slider 32 moves radially, the contact point between its inclined surface and the bottom of the support ring 31 will change. This relative motion between the inclined surface and the plane will be converted into a vertical component force, thereby lifting the support ring 31 upward. Conversely, when the slider 32 moves outward, the support ring 31 will descend under the action of gravity or auxiliary elastic elements. Through this ingenious inclined surface mechanism, the radial horizontal movement of the locking block 44 is converted into the vertical lifting and lowering movement of the support ring 31, thereby changing the vertical distance between the self-heating pack and the lower heat-conducting plate 13, that is, changing the size of the heat conduction gap. When the distance increases, the thermal resistance increases and the transfer efficiency decreases. When the distance decreases, the thermal resistance decreases and the transfer efficiency increases.

[0071] The aforementioned lifting mechanism works in conjunction with the radial adjustment mechanism 4. To verify the direct impact of the core action of the clamping block on the heat source response rate, a special test was conducted under fixed ventilation and heat transfer distance conditions. The results are shown in the table below:

[0072]

[0073] As shown in the table above, by simply changing the tightness of the clamping block 44, the steady-state temperature can be continuously and precisely controlled within the range of 40.5℃ to 63.8℃. In particular, from loosening to fully tightening, the temperature can drop rapidly by more than 23℃ within 30 seconds, and the reaction rate is significantly reduced. This conclusively proves that by driving the clamping block 44 to tighten radially through the adjustment mechanism 5, the contact area of ​​the reactants can be effectively reduced through physical compression, and oxygen diffusion can be hindered, thereby achieving direct and rapid suppression of the exothermic chemical reaction. This is one of the core mechanisms of the present invention for achieving rapid and precise temperature control.

[0074] The vertical block 43 at the bottom of the movable pressure plate 42 cooperates with the clamping block 44 for holding the self-heating pack on the inner wall of the moxibustion cylinder 11 through the adjustment mechanism 5. One side of the clamping block 44 is connected to the inner wall of the moxibustion cylinder 11 through an elastic element, which provides a radial reset tendency for the clamping block 44. The bottom of the clamping block 44 is connected to the slider 32 through the connecting rod 47.

[0075] Specifically, the two ends of the connecting rod 47 are hinged to the locking block 44 and the slider 32 respectively through ball joints or movable pins. This movable connection method can adapt to the complex angle changes that may occur when the locking block 44 swings and the slider 32 slides, ensuring smooth power transmission. A moving block is provided at the bottom of the slider 32, and a moving groove extending radially is provided at the corresponding position on the heat conduction plate 13, forming a sliding pair to accurately guide the slider 32 to move along a predetermined trajectory and bear radial force. This sliding pair structure is a conventional design in the mechanical field and will not be described in detail here.

[0076] In summary, the present invention cleverly transforms the movement of the radial adjustment mechanism 4 into precise control of the distance to the heat source through the support mechanism 3 and the inclined lifting mechanism. This not only adds an independent dimension of heat regulation, but more importantly, it is linked with the reaction control dimension in Example 1 through the same set of drive mechanisms, realizing integrated control, greatly simplifying user operation, and improving the overall performance of temperature control.

[0077] As can be seen from Embodiments 1 and 2, the present invention innovatively integrates three key factors affecting the final moxibustion temperature—airflow regulation, self-heating pack compaction regulation, and heat source heat transfer distance regulation—into a unified mechanical linkage system driven by a rotating moxibustion cover 1. Users do not need to operate multiple controls separately; they can synchronously, continuously, and linearly change all the above parameters by simply rotating the moxibustion cover 1 in both directions. This achieves rapid, accurate, and stable control of the moxibustion temperature, effectively solving the problems of slow response and poor temperature control accuracy of smokeless moxibustion therapy devices in the background art.

[0078] The working principle of this invention is as follows:

[0079] First, the user places the activated self-heating pack into the moxibustion cylinder 11, where it begins to generate heat through an oxidation reaction with the air. Then, the moxibustion cover 1 is placed on the body.

[0080] When the user feels the temperature is insufficient, rotating the moxibustion cover 1 counterclockwise triggers the following three simultaneous effects:

[0081] First, the overlap area between the ventilation groove 22 on the moxibustion cover 1 and the ventilation hole 21 on the moxibustion cylinder 11 is increased, thus increasing oxygen supply.

[0082] Second, by adjusting mechanism 5, the drive block 44 is radially released, making the self-heating pack fluffy and allowing the internal reactants to come into more full contact with air;

[0083] Third, the support ring 31 is driven to descend via the connecting rod 47 and the inclined plane mechanism, thereby reducing the thermal resistance between the self-heating pack and the skin.

[0084] The three elements work together to increase heat generation from the heat source and make heat transfer more efficient, resulting in a rapid rise in temperature.

[0085] When the user feels the temperature is too high, rotate the moxibustion cover 1 clockwise. This action simultaneously triggers the following three opposing effects:

[0086] First, the reduced opening of vent 21 restricts oxygen supply;

[0087] Second, the card block 44 radially clamps and compacts the self-heating pack, physically inhibiting the reaction;

[0088] Third, the support ring 31 is raised, increasing thermal resistance.

[0089] The three working together can quickly reduce heat generation and hinder heat transfer, achieving rapid cooling and effectively preventing burns.

[0090] Throughout the entire process of use, the movable pressure plate 42 always elastically presses the top of the self-heating pack, and together with the rotatable rotating plate 46, it not only fixes the self-heating pack to prevent it from shaking, but also prevents it from rotating with the moxibustion cover 1, thus ensuring the stability of the heat source position and the reliability of the device operation.

[0091] In summary, this invention achieves multi-dimensional, rapid, and precise coordinated control of the temperature of smokeless moxibustion through a highly integrated pure mechanical linkage system. It not only fundamentally solves the problems of slow temperature control response and poor accuracy in existing technologies, but also has many advantages such as smokeless, safe, easy to operate, stable and reliable, providing an innovative moxibustion device for modern moxibustion therapy.
