Description

Technical Field

[0001] This invention relates to the field of thermotherapy device technology, and in particular to a thermotherapy device integrating active heat insulation and bottom directional ash removal structure. Background Technology

[0002] Heat therapy is an important component of traditional Chinese medicine. It involves applying heat generated by burning moxa wool or moxa sticks to acupoints or affected areas to achieve therapeutic effects such as warming and unblocking meridians, dispelling cold and dampness, and regulating qi and blood. In recent years, with the increasing emphasis on health and wellness, various heat therapy devices have been widely used and developed.

[0003] Existing hyperthermia devices typically consist of a shell, an insulation cylinder, and a fuel holder. The inner cavity of the insulation cylinder is filled with the hyperthermia combustion material, which is then secured inside the device by the fuel holder. However, these traditional hyperthermia devices still have some shortcomings in practical use.

[0004] First, the combustion of thermotherapy materials generates a large amount of heat, and traditional devices often lack effective active insulation mechanisms. Even when thermotherapy stops, heat continues to be conducted downwards through the bottom of the device to the skin, easily causing burns. Although some devices are equipped with insulation panels or layers, they are mostly fixed structures, unable to flexibly switch between thermotherapy and standby modes according to the needs of thermotherapy. Second, the combustion of thermotherapy materials produces a large amount of ash. Although traditional devices have ash collection screens or cups inside, they lack directional collection capabilities. Ash may still escape from the gaps at the bottom of the device or accumulate there, easily falling onto the skin and causing burns, and is also inconvenient to clean. Summary of the Invention

[0005] In view of this, the purpose of this invention is to propose a thermotherapy device that integrates active heat insulation and bottom directional ash removal structure, so as to solve the technical problems of existing thermotherapy devices lacking the function of flexibly switching between thermotherapy and heat insulation working modes, and the inconvenience and difficulty in ash collection and cleaning.

[0006] Based on the above objectives, the present invention provides a thermotherapy device integrating active heat insulation and bottom directional ash removal structure, including an outer shell and a heat insulation cylinder. The inner cavity of the heat insulation cylinder is used to fill the thermotherapy combustion material. The heat insulation cylinder is coaxially assembled inside the outer shell, and there is an annular sandwich between the outer shell and the heat insulation cylinder. The bottom of the outer shell and the bottom of the heat insulation cylinder are both through-opened.

[0007] A fuel fixing seat fixed to the top wall of the heat insulation cylinder, the fuel fixing seat being used to fix the heat therapy material, further comprising:

[0008] A heat insulation component is disposed between the inner cavity of the heat insulation cylinder and the bottom opening of the outer shell. The heat insulation component is used to block the heat generated by the heat therapy material from being conducted downward to the human skin when the heat therapy is stopped.

[0009] An ash collection component is installed between the lower end of the outer shell and the active heat insulation component. The ash collection component is used to collect the ash generated by the heat therapy combustion in a directional and concentrated manner to prevent the ash from falling directly into the human body and causing burns.

[0010] Preferably, the end face of the fuel holder is provided with a plurality of barbed hooks arranged alternately from top to bottom, the barbed hooks being used to hook and fix the columnar heat therapy combustion material.

[0011] Preferably, the thermal insulation component includes:

[0012] An adjustment plate is fixedly installed in the inner cavity of the heat insulation cylinder and located directly below the fuel fixing seat. The adjustment plate surface is divided into a heat conduction area and a solid heat insulation area. The heat conduction area has a through heat conduction window, and the solid heat insulation area is a sealed solid heat insulation board.

[0013] A support cylinder is threaded onto the bottom opening of the outer casing. The bottom surface of the adjustment disc is attached to the upper end surface of the support cylinder, and the bottom of the support cylinder is through-hole. Several heat radiation windows are evenly opened along the circumference at the upper end of the support cylinder, and each heat radiation window can be aligned and coincide with the heat conduction window.

[0014] An ash collection hole is coaxially opened at the center of the adjustment disc, the ash collection component is coaxially disposed at the center of the support cylinder, and the fuel fixing seat is vertically positioned above the ash collection hole.

[0015] A rotating part is rotatably mounted between the top of the outer shell and the top of the heat insulation cylinder. The rotating part is used to drive the heat insulation cylinder to rotate around the central axis, so that the heat insulation cylinder synchronously drives the adjusting plate to rotate relative to the support cylinder.

[0016] Preferably, the rotating part is an integral rotating rod, which is rotatably assembled to the top center of the outer shell via a bearing, and the lower end of the rotating rod is fixedly connected to the top surface of the heat insulation cylinder;

[0017] A mode indicator component is installed between the top of the rotating rod and the top surface of the outer shell to visually distinguish between the current heat therapy mode and the heat insulation standby mode.

[0018] Preferably, the pattern indication component includes:

[0019] An adjusting cap that is fixedly fitted to the top of the rotating rod and a pointer that is fixed to the upper surface of the adjusting cap;

[0020] A fan-shaped visual color mark is fixedly laid on the top surface of the outer shell. The visual color mark is divided into a green mark segment and a red mark segment. The green mark segment corresponds to the heat therapy working mode, and the red mark segment corresponds to the heat insulation standby mode. When the rotating adjustment cap drives the pointer to rotate synchronously, the pointer can indicate the current working level of the device when it points to the corresponding color mark segment.

[0021] Preferably, there are three heat conduction windows and three heat radiation windows. The three heat conduction windows are evenly distributed at equal angles along the circumference of the adjustment disc, and the three heat radiation windows are evenly distributed at equal angles along the upper circumference of the support cylinder. Each heat conduction window can completely overlap and be aligned with a single heat radiation window.

[0022] Preferably, the heat therapy device further includes a speed setting component, which is disposed between the lower inner wall of the heat insulation cylinder and the upper outer wall of the support cylinder, so as to automatically lock and fix itself after the adjustment disc switches between the heat therapy and heat insulation working modes. The speed setting component includes:

[0023] Six equidistant limiting grooves are opened along the circumference of the inner wall at the lower end of the heat insulation cylinder;

[0024] Three assembly slots are equidistantly opened along the circumference of the upper outer wall of the support cylinder;

[0025] A rolling ball is mounted inside the assembly groove, wherein the ball partially extends out of the assembly groove and is engaged in a corresponding limiting groove to achieve circumferential limiting;

[0026] A spring is installed inside the assembly groove, with one end abutting against the surface of the ball and the other end fixed to the inner wall of the assembly groove.

[0027] Preferably, the dust collection component includes:

[0028] A ash guide pipe is fixedly installed at the center of the upper end of the support cylinder. The ash guide pipe is divided into a tapered ash dropping section that is wider at the top and narrower at the bottom and a downwardly inclined material guiding section. The upper end of the tapered ash dropping section is connected to the ash dropping hole.

[0029] A mounting port is provided on the lower side wall of the housing, and a dust collection box can be detachably inserted into the lower interior of the housing through the mounting port;

[0030] A ash guide groove is provided on the lower side wall of the support cylinder. The discharge end of the material guide section is connected to the inner cavity of the ash collection box through the ash guide groove, so that the combustion ash falls into the ash collection box through the ash drop hole, ash guide pipe and ash guide groove for centralized collection.

[0031] Preferably, a first magnetic positioning component is fixedly installed on the outer walls of both the left and right sides of the dust collection box, and a second magnetic positioning component is fixedly installed on the side walls of the mounting opening. The first and second magnetic positioning components have opposite magnetic poles and are magnetically attracted to each other.

[0032] Preferably, the top surface of the outer casing has a plurality of tangential air inlets evenly distributed circumferentially, and the lower sidewall of the outer casing has tangential air outlets evenly distributed circumferentially, each corresponding to one of the air inlets.

[0033] The beneficial effects of this invention are as follows: The thermotherapy device of this invention, which integrates active heat insulation and a bottom-oriented ash removal structure, achieves active switching between thermotherapy mode and heat-insulating standby mode through the rotating and cooperating structure of the adjusting disc and the support cylinder, and the setting of the positioning component. When thermotherapy is needed, the heat-conducting window and the heat radiation window coincide and align, forming a through-type heat radiation path, allowing heat to be efficiently transferred downwards to the human body. When it is necessary to stop thermotherapy, simply rotating the adjusting disc to seal the heat radiation window with the solid heat insulation area completely cuts off the downward heat radiation path, fundamentally avoiding the problem of residual heat continuing to conduct and burn the skin after thermotherapy is stopped. Compared with traditional fixed heat insulation structures, the active heat insulation mechanism of this invention is more flexible and reliable.

[0034] A complete directional ash discharge channel is constructed through the coordinated operation of ash discharge holes, conical ash guide pipes, ash guide troughs, and ash collection boxes. The ash produced by combustion falls into the ash guide pipes under the action of gravity through the ash discharge holes, and then is directionally guided into the ash collection box for centralized collection. There is no ash scattering throughout the process, completely avoiding the risk of burns caused by ash falling directly onto human skin.

[0035] By adjusting the cap, pointer, and fan-shaped visual color mark, users can intuitively determine whether the device is currently in heat therapy mode or heat insulation standby mode by observing the color mark segment indicated by the pointer. The green segment corresponds to the heat therapy working mode, and the red segment corresponds to the heat insulation standby mode, making it clear at a glance and effectively avoiding accidental operation.

[0036] Through the tangential air inlet on the top surface of the outer shell and the tangential air outlet on the lower side wall, external airflow enters the annular interlayer between the outer shell and the insulation cylinder through the air inlet. As it exits through the tangential air outlet, it forms a spiraling upward air curtain, which can continuously carry away the heat dissipated from the outer wall of the insulation cylinder, thus helping to enhance the overall heat insulation effect. This air curtain heat insulation mechanism complements the active heat insulation mechanism of the regulating plate-support cylinder, forming a dual heat insulation protection system.

[0050] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments.

[0051] It should be noted that, unless otherwise defined, the technical or scientific terms used in this invention should have the ordinary meaning understood by one of ordinary skill in the art to which this invention pertains. The terms "first," "second," and similar terms used in this invention do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Terms such as "comprising" or "including" mean that the element or object preceding the word encompasses the elements or objects listed following the word and their equivalents, without excluding other elements or objects. Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0052] In a first aspect, the present invention provides a thermotherapy device integrating active heat insulation and a bottom-oriented ash removal structure, such as... Figure 1-10 As shown, it includes an outer shell 1 and a heat insulation cylinder 2. The inner cavity of the heat insulation cylinder 2 is used to fill the heat therapy combustion material (such as moxa sticks, moxa cones, etc.). The heat insulation cylinder 2 is coaxially assembled inside the outer shell 1, and there is an annular sandwich between the outer shell 1 and the heat insulation cylinder 2. The bottom of the outer shell 1 and the bottom of the heat insulation cylinder 2 are both opened through to allow heat to be conducted downward to the human skin and ash to be discharged downward.

[0053] The fuel fixing seat 3, fixed to the top wall of the heat insulation cylinder 2, is used to fix the heat therapy material and also includes:

[0054] A heat insulation component is provided between the inner cavity of the heat insulation cylinder 2 and the bottom opening of the outer shell 1. The heat insulation component is used to block the heat generated by the heat therapy material from being conducted downward to the human skin when the heat therapy is stopped.

[0055] The ash collection component is installed between the lower end of the outer shell 1 and the active heat insulation component. The ash collection component is used to collect the ash produced by the heat therapy combustion in a directional and concentrated manner to prevent the ash from falling directly into the human body and causing burns.

[0056] In this embodiment, the fuel holder 3 has several barbed hooks arranged alternately from top to bottom on its end face. These barbed hooks are used to hook and fix the columnar heat therapy burning material. The barbed hooks on the end face of the fuel holder 3 are integrally stamped from 304 stainless steel. The barbed hook angle is 30°, the hook length is 5mm, and adjacent barbed hooks are staggered vertically. In use, the lower end of the columnar moxa stick or moxa cone is inserted into the barbed hook area, and the hook tip of the barbed hook embeds into the material, achieving a firm fixation of the material. Even if the weight of the material gradually decreases during combustion or the device is subjected to slight vibration, the barbed hooks can still maintain the hook and fixation of the material, preventing the material from accidentally falling off and ensuring the continuity and stability of the combustion process.

[0057] In this embodiment: the thermal insulation component includes:

[0058] An adjusting plate 4 is fixedly installed inside the heat insulation cylinder 2 and located directly below the fuel fixing seat 3. The adjusting plate 4 is divided into a heat conduction area and a solid heat insulation area. The heat conduction area has a through heat conduction window 5, and the solid heat insulation area is a sealed solid heat insulation plate. The adjusting plate 4 is made of high temperature resistant ceramic material or metal material. The heat conduction window 5 is a hollow through structure, without obstruction or heat insulation filling, to ensure efficient heat penetration.

[0059] The support cylinder 6 is threadedly fitted to the bottom opening of the outer shell 1. The outer wall of the lower end of the support cylinder 6 and the inner wall of the lower end of the outer shell 1 have interlocking threads. The bottom surface of the adjusting plate 4 is attached to the upper end surface of the support cylinder 6, and the bottom of the support cylinder 6 is through. Several heat radiation windows 7 are evenly opened along the circumference at the upper end of the support cylinder 6, and each heat radiation window 7 can be aligned and coincide with the heat conduction window 5.

[0060] An ash collection hole 8 is coaxially opened at the center of the adjustment plate 4, and the ash collection component is coaxially set at the center of the support cylinder 6. The fuel fixing seat 3 is vertically positioned above the ash collection hole 8. The ash collection hole 8 is designed so that the ash produced by the combustion of the thermotherapy material can fall naturally under the action of gravity and enter the ash collection component.

[0061] A rotating part 11 is rotatably mounted between the top of the outer casing 1 and the top of the heat insulation cylinder 2. The rotating part 11 drives the heat insulation cylinder 2 to rotate around its central axis, so that the heat insulation cylinder 2 synchronously drives the adjusting disc 4 to rotate relative to the support cylinder 6. The top of the rotating rod extends out of the top surface of the outer casing 1 for easy gripping and operation by the user.

[0062] In this embodiment: the rotating part 11 is an integral rotating rod, which is rotatably assembled to the top center of the outer shell 1 through a bearing, and the lower end of the rotating rod is fixedly connected to the top surface of the heat insulation cylinder 2;

[0063] A mode indicator component is installed between the top of the rotating rod and the top surface of the outer casing 1 to visually distinguish between the current thermotherapy mode and the heat-insulating standby mode. When the device is in thermotherapy mode, the heat-conducting windows 5 of the heat-conducting area of ​​the adjusting disc 4 and the heat radiation windows 7 of the support cylinder 6 overlap one-to-one, forming a through-type heat radiation path. The heat generated by the combustion of the thermotherapy material can be conducted downwards to the human skin through the heat-conducting windows 5 and the heat radiation windows 7 to achieve the thermotherapy effect. When the device is in heat-insulating standby mode, the solid heat-insulating area of ​​the adjusting disc 4 completely blocks the heat radiation windows 7, cutting off the downward heat radiation path. At this time, even if the thermotherapy material still has residual heat, the heat cannot be conducted to the human body through the solid heat-insulating area, thereby effectively avoiding the risk of burns after the thermotherapy stops. Compared with the traditional fixed heat insulation structure, the active heat insulation mechanism of this invention is more flexible and reliable.

[0064] In this embodiment: the mode indication component includes:

[0065] An adjusting cap fixedly fitted to the top of the rotating rod and a pointer 18 fixedly mounted on the upper surface of the adjusting cap;

[0066] A fan-shaped visual color mark 19 is fixedly laid on the top surface of the outer shell 1. The visual color mark 19 is divided into a green mark segment and a red mark segment. The green mark segment corresponds to the heat therapy working mode, and the red mark segment corresponds to the heat insulation standby mode. When the rotating adjustment cap drives the pointer 18 to rotate synchronously, the pointer 18 can indicate the current working level of the device when it points to the corresponding color mark segment.

[0067] When the user rotates the adjustment cap, it causes the pointer 18 to rotate synchronously. When pointer 18 points to the green indicator, it indicates that the device is currently in heat therapy mode, with the heat conduction window 5 and the heat radiation window 7 aligned, allowing heat to be conducted downwards normally. When pointer 18 points to the red indicator, it indicates that the device is currently in heat insulation standby mode, with the physical heat insulation area blocking the heat radiation window 7, cutting off heat conduction. By using pointer 18 in conjunction with the color indicators, users can clearly determine the current working status of the device, effectively avoiding burns or poor therapeutic effects caused by misjudging the mode.

[0068] In this embodiment, three heat-conducting windows 5 and three heat-radiating windows 7 are provided. The three heat-conducting windows 5 are evenly distributed at equal angles along the circumference of the adjusting disk 4, and the three heat-radiating windows 7 are evenly distributed at equal angles along the upper circumference of the support cylinder 6. Each heat-conducting window 5 can completely overlap and align with each heat-radiating window 7. Specifically, the size and shape of each heat-conducting window 5 match the size and shape of each heat-radiating window 7. When the adjusting disk 4 is rotated to a specific angle, each heat-conducting window 5 can completely overlap and align with each heat-radiating window 7, forming a maximized heat radiation path.

[0069] In this embodiment: the heat therapy device further includes a gear positioning component, which is disposed between the lower inner wall of the heat insulation cylinder 2 and the upper outer wall of the support cylinder 6, so as to automatically lock and fix itself after the adjustment plate 4 switches between the heat therapy and heat insulation working modes. The gear positioning component includes:

[0070] Six limiting grooves 12 are equidistantly opened along the circumferential direction of the inner wall of the lower end of the heat insulation cylinder 2;

[0071] Three assembly slots 13 are equidistantly opened along the circumferential direction of the upper outer wall of the support cylinder 6;

[0072] The ball bearing 14 is rolled inside the assembly groove 13. The ball bearing 14 extends out of the assembly groove 13 and is engaged in the corresponding limiting groove 12 to achieve circumferential limiting.

[0073] A spring 15 is installed inside the assembly groove 13. One end of the spring 15 abuts against the surface of the ball 14, and the other end is fixed to the inner wall of the assembly groove 13.

[0074] When the user rotates the adjusting cap to drive the heat insulation cylinder 2 to rotate, the heat insulation cylinder 2 drives the limiting groove 12 to rotate relative to the ball bearing 14. The ball bearing 14, under the elastic force of the spring 15, always tends to extend outwards. When the limiting groove 12 rotates to the position corresponding to the ball bearing 14, the ball bearing 14 automatically engages in the limiting groove 12 under the action of the spring 15, achieving circumferential positioning. Since there are six limiting grooves 12 (three corresponding to each of the heat therapy and heat insulation modes), and three ball bearings 14, when all three engage in their respective limiting grooves 12 simultaneously, stable triangular positioning can be achieved, ensuring that the adjusting disc 4 can be firmly fixed in either the heat therapy mode or the heat insulation standby mode, and will not rotate accidentally due to device vibration or external force.

[0075] In this embodiment: the dust collection component includes:

[0076] A guide pipe 9 is fixedly installed at the center of the upper end of the support cylinder 6. The guide pipe 9 is divided into a conical ash-falling section that is wider at the top and narrower at the bottom, and a downwardly inclined material-guiding section. The upper end of the conical ash-falling section is connected to the ash-falling hole 8. Its conical structure helps guide the ash to converge and fall towards the center. The material-guiding section forms an angle of 45° to 60° (preferably 55°) with the horizontal plane to ensure that the ash can slide smoothly under the action of gravity. The outlet end of the material-guiding section is provided with a guide slope so that the discharged ash falls accurately into the external ash collection container in a preset direction, completely avoiding ash scattering.

[0077] An installation port 101 is provided on the lower side wall of the outer casing 1, and a dust collection box 10 is detachably inserted into the lower interior of the outer casing 1 through the installation port 101; a handle is fixed on the outer wall of the dust collection box 10 to facilitate the pulling out of the dust collection box 10.

[0078] A guide trough 601, located on the lower side wall of the support cylinder 6, connects the discharge end of the guide section to the inner cavity of the ash collection box 10. This allows the combustion ash to fall directionally through the ash drop hole 8, the ash guide pipe 9, and the guide trough 601 into the ash collection box 10 for centralized collection. Under gravity, the ash produced by the combustion of the thermotherapy material first falls through the ash drop hole 8 into the conical ash drop section of the ash guide pipe 9, then slides downwards along the guide section, and is then directionally guided into the ash collection box 10 for centralized collection via the guide trough 601. The entire ash discharge path is closed and directional, preventing ash from scattering inside the device and from coming into contact with human skin, thus eliminating the risk of ash burns at the source.

[0079] In this embodiment: First magnetic positioning components 16 are fixedly installed on the outer walls of both sides of the dust collection box 10, and second magnetic positioning components 17 are fixedly installed on the side walls of the mounting port 101 respectively. The first magnetic positioning component 16 and the second magnetic positioning component 17 have opposite magnetic poles and are magnetically attracted to each other.

[0080] Both the first magnetic positioning component 16 and the second magnetic positioning component 17 are high-temperature resistant neodymium iron boron permanent magnets. When the ash collection box 10 needs to be installed, the user pushes the ash collection box 10 into the lower end of the outer shell 1 along the mounting opening 101. When the first magnetic positioning component 16 and the second magnetic positioning component 17 approach each other, they automatically attract and position themselves under the action of magnetic attraction. At the same time, the inlet end of the ash collection box 10 and the outlet end of the ash guide trough 601 are automatically aligned and connected. When the ash collection box 10 needs to be cleaned, the user only needs to pull the handle on the ash collection box 10 to overcome the magnetic attraction and pull the ash collection box 10 out of the mounting opening 101. After cleaning, it can be pushed back in to complete the installation. The operation is extremely simple.

[0081] In this embodiment: several tangential air inlets 20 are evenly opened on the top surface of the outer shell 1 along the circumference, and tangential air outlets 21 corresponding to the air inlets 20 are evenly opened on the lower side wall of the outer shell 1 along the circumference.

[0082] Specifically, the tangential air inlet 20 and tangential air outlet 21 are arranged such that there are six tangential air inlets 20 on the top surface of the outer shell 1 and six tangential air outlets 21 at the bottom, evenly arranged in a ring array along the circumference. The tangential angle of the openings is 30°, allowing external airflow to enter and exit the annular interlayer between the outer shell 1 and the heat insulation cylinder 2 in a tangential direction. After the external cold air enters the annular interlayer through the tangential air inlet 20, it flows spirally downward along the annular interlayer, flows over the outer wall surface of the heat insulation cylinder 2, and carries away the heat dissipated from the outer wall of the heat insulation cylinder 2. Subsequently, the airflow is discharged through the tangential air outlet 21, and the discharged airflow forms a spiral rising air curtain around the device. Thus, on the one hand, the continuously flowing airflow can continuously remove the heat from the outer wall of the heat insulation cylinder 2, reduce the surface temperature of the outer shell 1, and prevent the user from being burned due to excessive heat conduction. On the other hand, the spiral air curtain itself can act as a pneumatic heat insulation barrier, further blocking the radiation and conduction of heat to the outside of the outer shell 1. It also complements the active heat insulation components of the regulating plate 4 and the support cylinder 6, forming a dual heat insulation protection system, which significantly improves the overall heat insulation performance and safety performance of the device.

[0083] Working principle: The user first inserts the lower end of the columnar heat therapy material (such as moxa stick) into the barbed hook area of ​​the fuel fixing seat 3, so that the barbed hook firmly hooks and fixes the material. Then, the upper end of the material is ignited to start it burning, and the support cylinder 6 is threaded into the inner wall of the lower end of the outer shell 1;

[0084] The user rotates the adjustment cap and observes the visual color mark 19 through pointer 18. When pointer 18 points to the green mark segment, it indicates that the heat conduction window 5 of the adjustment disc 4 has completely aligned with the heat radiation window 7 of the support cylinder 6. At this time, the heat generated by the combustion of the material is conducted downwards to the human skin through the heat conduction window 5 and the heat radiation window 7, achieving a thermotherapy effect. Simultaneously, the ball bearing 14, under the action of spring 15, engages in the corresponding limiting groove 12, firmly locking the adjustment disc 4 in the thermotherapy working mode.

[0085] When it is necessary to pause or stop heat therapy, the user rotates the adjustment cap in the opposite direction and observes the visual color mark 19 through pointer 18. When pointer 18 points to the red mark segment, it indicates that the solid heat insulation area of ​​the adjustment disc 4 has completely blocked the heat radiation window 7. At this time, the heat generated by the combustion of the material is blocked by the solid heat insulation area and cannot continue to be conducted downwards to the human body, effectively avoiding the risk of burns. Under the action of spring 15, the ball bearing 14 is engaged in the corresponding limiting groove 12, firmly locking the adjustment disc 4 in the heat insulation standby mode;

[0086] Throughout the heat treatment process, the ash produced by the combustion of materials continuously falls through the ash drop hole 8 into the ash guide pipe 9 under the action of gravity, and then is directed into the ash collection box 10 for centralized collection through the ash guide groove 601. After the heat treatment is completed or when the ash collection box 10 is full, the user can pull out the ash collection box 10 from the installation port 101, clean the ash, and then reinstall it.

[0087] During the operation of the device, external cold air continuously enters the annular interlayer through the tangential air inlet 20 and is discharged through the tangential air outlet 21 to form a spiral rising air curtain, which continuously carries away the heat dissipated from the outer wall of the heat insulation cylinder 2, thus helping to enhance the overall heat insulation effect.

[0088] Those skilled in the art should understand that the discussion of any of the above embodiments is merely exemplary and is not intended to imply that the scope of the invention is limited to these examples; within the framework of the invention, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of the different aspects of the invention as described above, which are not provided in detail for the sake of brevity. Any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the invention should be included within the scope of protection of the invention.
