Technical Field

[0002] Moxibustion is a traditional health care method. Due to its low technical requirements for operation, it is increasingly accepted and used by the general public. At present, the moxibustion method still mainly uses the traditional manual method or is combined with some simple auxiliary tools for moxibustion application, which is very inconvenient to use. The patent applications with publication numbers CN112315783A and CN 211863313U both propose a solution to control the forward or backward movement of the moxa stick, and then adjust the height of the moxa stick from the human skin to adjust the moxibustion temperature.

The bottom end of the combustion control machine base is detachably connected to the combustion head. Threads with a length satisfying the advancing and retreating range of the moxa stick socket are provided on the inner wall of the combustion control machine base. A machine base guiding groove that is axially disconnected from the threads and has a length satisfying the advancing and retreating range of the moxa stick feeding motor base is also opened on the inner wall of the combustion control machine base;

[0047] The idea of the present utility model is that for a burning object, changing the oxygen content of its burning surface can change its burning firepower. Based on this principle, the present utility model proposes to stably send fresh air by a blower, cooperate with a combustion control tube to limit the burning surface of the moxa stick periphery, and adjust the contact amount between the burning surface and the fresh air, so as to control the oxygen content of the burning surface of the moxa stick, and further control the burning firepower of the moxa stick. Then, a controller is equipped to use a temperature sensing wire to feedback the temperature to immediately adjust the position of the moxa stick, and a controllable and stable moxibustion heat source can be obtained. Based on the controllable and stable moxibustion heat source provided by the moxa stick combustion control machine, according to the actual needs of moxibustion treatment, various shapes and functions of moxibustion seats and auxiliary supports are equipped to solve the problems of handling of moxa ash and smoke generated during the installation and moxibustion process of the moxa stick combustion control machine.

[0048] To facilitate the understanding of the present utility model, the present utility model will be described more comprehensively below with reference to the relevant drawings. Typical embodiments of the present utility model are shown in the drawings. However, the present utility model can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the disclosure of the present utility model more thorough and comprehensive. It should be understood that the embodiments of the present utility model and the specific features in the embodiments are detailed descriptions of the technical solutions of the present application, rather than limitations on the technical solutions of the present application. Without conflict, the embodiments of the present utility model and the technical features in the embodiments can be combined with each other.

[0049] Embodiment 1

[0050] The moxa stick combustion control machine of this embodiment is used to be installed on a moxibustion seat for use, and the two cooperate to form a moxibustion machine. The moxa stick combustion control machine is responsible for burning the moxa stick to generate hot smoke and entering the moxibustion seat, and the moxibustion seat is responsible for solving the problems of handling moxa ash and smoke generated during the installation of the moxa stick combustion control machine and the moxibustion process.

[0051] Reference Figure 1 , the moxa stick combustion control machine includes a rotary forward and backward moxa stick mechanism 10 and a combustion head 20 that are detachably connected up and down. In this embodiment, the entire body of the moxa stick combustion control machine is generally cylindrical, and the rotary forward and backward moxa stick mechanism 10 and the combustion head 20 are specifically threadedly connected. Among them, an acupuncture moxibustion stick 30 can be vertically inserted into the rotary forward and backward moxa stick mechanism 10 and can drive the acupuncture moxibustion stick 30 to rotate forward and backward in the vertical direction. The rotary forward and backward moxa stick mechanism 10 includes a air supply channel surrounding the acupuncture moxibustion stick 30. The rotary forward and backward moxa stick mechanism 10 includes a combustion control machine base 11, an acupuncture moxibustion stick socket 12, a moxa stick feeding motor 13, and a moxa stick feeding motor base 14. The combustion head 20 includes a combustion control pipe 21, a ventilation pipe 22, etc.

[0052] Reference Figure 2 , the combustion control machine base 11 determines the main appearance of the entire rotary forward and backward moxa stick mechanism 10. The combustion control machine base 11 is generally cylindrical with both ends open. The bottom end of the combustion control machine base 11 is detachably connected to the combustion head 20. Specifically, the bottom end of the combustion control machine base 11 is inserted into the upper end of the ventilation pipe 22. Threads are provided on the outer side wall of the bottom end of the combustion control machine base 11, and threads are provided on the inner side wall at the upper end inlet position of the ventilation pipe 22. The bottom end of the combustion control machine base 11 is threadedly connected to the upper end inlet position of the ventilation pipe 22. The moxa stick feeding motor base 14 and the acupuncture moxibustion stick socket 12 are located inside the combustion control machine base 11, and the moxa stick feeding motor base 14 is located above the acupuncture moxibustion stick socket 12. Threads are provided on the inner wall of the combustion control machine base 11 with a length that meets the forward and backward range of the acupuncture moxibustion stick socket 12, and the acupuncture moxibustion stick socket 12 is threadedly connected to the combustion control machine base 11. Reference Figure 3, the moxa stick socket 12 is in a cylindrical stepped shape, specifically composed of a large cylindrical head and a small head, and the small head has a reduced diameter relative to the large head. An external thread is provided on the outer peripheral side of the large head for threaded engagement with the inner wall of the combustion control base 11. At one end of the interior of the moxa stick socket 12 near the large head, there is a cavity larger than the body of the moxa delivery motor 13 for accommodating part of the body of the moxa delivery motor 13. At the end face of the cavity near the small head, a motor shaft connection hole 1202 for mating with the output shaft of the moxa delivery motor 13 extends along the direction of the small head. The motor shaft connection hole 1202 is coaxial with the cylindrical large head and small head. Such a cavity setting can reduce the overall length of the combustion control machine. The radial dimension of the small head matches that of the combustion control tube 21 and can be inserted into the combustion control tube 21, and has a length similar to that of the combustion control tube 21, so that as much of the moxa stick as possible can be pushed into the combustion chamber, reducing waste caused by excessive moxa sticks remaining in the combustion control tube 21 and unable to burn at the end of combustion. At least one insertion pin 1201 is connected to the end face of the small head facing away from the large head, and the insertion pin 1201 extends parallel to the axial direction for inserting the moxa stick 30. Preferably, the edge of the end face of the small head facing away from the large head continues to extend in the direction away from the large head to form a cylindrical thin-walled sleeve 1204. When the moxa stick 30 is inserted into the insertion pin 1201, it will also be inserted into the thin-walled sleeve 1204. In this way, the thin-walled sleeve 1204 and the insertion pin 1201 jointly connect the moxa stick 30, ensuring coaxiality with the moxa stick socket 12 when driving the moxa stick 30 to rotate and move forward and backward. A machine base guide groove 111 with an axially disconnected thread and a length satisfying the forward and backward movement range of the moxa delivery motor base 14 is also provided on the inner wall of the combustion control base 11. Refer to Figure 4 , the moxa delivery motor base 14 is cylindrical, and motor base guide strips 142 parallel to its axial direction are provided on its outer side wall. The motor base guide strips 142 are slidably engaged with the machine base guide groove 111. The moxa delivery motor 13 is installed on the moxa delivery motor base 14 with the motor shaft facing downwards, and the motor shaft of the moxa delivery motor 13 is connected to the aforementioned motor shaft connection hole 1202 to drive the moxa stick socket 12 and the moxa stick 30 to rotate and move forward and backward.

[0053] Continue to refer to Figure 3 , 4 , a circle of moxa stick socket air vents 1203 distributed around the motor shaft connection hole 1202 is provided in the large head of the moxa stick socket 12. The moxa stick socket air vents 1203 axially penetrate the large head of the moxa stick socket 12. A circle of motor base air vents 141 distributed around its central axis is provided in the moxa delivery motor base 14. The motor base air vents 141 axially penetrate the moxa delivery motor base 14. The space between the motor base air vents 141, the moxa delivery motor base 14 and the moxa stick socket 12, the moxa stick socket air vents 1203, and the space between the moxa stick socket 12 and the flange 221 of the combustion head 20 form a air supply channel. It can be understood that as long as the air channel is vertically connected, there can be more structural forms.

[0054] Continue to refer to Figure 1 , in combination with Figure 5-6 , preferably, in this embodiment, a blower seat 15 is further installed at the top of the combustion control machine base 11. The blower seat 15 is cylindrical. An external thread is provided on the outer side wall of the top of the combustion control machine base 11, and an internal thread is provided at the bottom end of the inner wall of the blower seat 15. The blower seat 15 can be threadedly installed on the top of the combustion control machine base 11. The top of the blower seat 15 is open and a protective net 16 is installed. A blower 17 is installed inside the blower seat 15. A flow blocking piece 28 is arranged below the blower 17. When the blower motor seat 14 moves upward to the limit position, it abuts against the flow blocking piece 28. The flow blocking piece 28 is generally in the shape of a hollow flange. The hollow part is a flow blocking piece air passage 280 that penetrates up and down. The outer periphery of the flow blocking piece 28 matches the size of the air outlet of the blower seat 15. The vertical projection of the shielding surface between the outer periphery and the hollow part covers the motor seat air passage 141. The vertical projection of the flow blocking piece air passage 280 avoids the motor seat air passage 141, so that when the blower motor seat 14 moves upward to the limit position, the motor seat air passage 141 is completely blocked by the flow blocking piece 28. After the blower 17 is started, the air flow enters the blower seat 15 from the protective net 16, and then enters the air supply passage inside the combustion control machine base 11 through the flow blocking piece air passage 280 and the space between the flow blocking piece 28 and the blower motor seat 14.

[0055] Specifically, the flow blocking piece 28 is clamped and installed between the mating surface of the top of the combustion control machine base 11 and the blower seat 15. The function of the flow blocking piece 28 is that when the blower motor seat 14 rises close to the flow blocking piece 28, the shielding surface can quickly reduce or even cut off the passage of the air flow, and in the subsequent automatic control, the sensed temperature can be quickly reduced, so that the blower motor 13 stops working. The above separate setting of the flow blocking piece 28 is only for convenience of description. In fact, the flow blocking piece 28 can also be a structure integrated with the blower seat 15, that is, the bottom end surface of the blower seat 15 is directly used as the shielding surface. Or when changing the connection position of the blower seat 15 on the combustion control machine base 11, according to the action of the blower motor 13 dragging its components to rise, other forms of quickly blocking the air flow can be realized.

[0056] During use, the air volume of the air blower 17 is first adjusted to the required fixed air volume, and then the contact amount between the combustion surface and fresh air is adjusted. It can be understood that the position of the air blower 17 is not restricted and can also be separately arranged outside. An inlet is provided on the outer peripheral wall of the combustion control base 11 to communicate with the above-mentioned air supply channel. The function of automatically blocking the air flow by the upward movement of the air supply motor base 14 still holds. Specifically, when the above-mentioned inlet is arranged within the axial movement range of the air supply motor base 14 and communicates with the above-mentioned air supply channel, the outer peripheral wall of the air supply motor base 14 plays a role in blocking the inlet. When the above-mentioned inlet is arranged within the axial movement range of the large end of the moxa stick socket 12 and communicates with the above-mentioned air supply channel, the threaded surface of the large end of the moxa stick socket 12 plays a role in blocking the inlet. Of course, without considering the automatic blocking of the air flow, the above-mentioned inlet can also be arranged on the side wall of the ventilation pipe 22 to directly communicate with the annular air flow space 300, and there is no need to open an air passage on the corresponding moxa stick socket 12 and air supply motor base 14.

[0057] The combustion control pipe 21 is located inside the ventilation pipe 22, and an annular air flow space 300 communicating with the air supply channel is formed between them. The inlet of the combustion control pipe 21 is higher than the inlet of the ventilation pipe 22. Preferably, the combustion control pipe 21 includes a tubular main body, an elastic sealing ring 213, and a sealing ring seat 214. Specifically, the top inlet of the tubular main body of the combustion control pipe 21 is enlarged in diameter to form the sealing ring seat 214, and the elastic sealing ring 213 is nested inside the sealing ring seat. The inlet position of the ventilation pipe 22 is threadedly connected to the bottom end of the combustion control base 11. The ventilation pipe 22 is connected to the waist position of the combustion control pipe 21 through a radially arranged flange 221 near its inlet position. A flange ventilation hole 2211 penetrating through its thickness is opened on the flange 221, and the air supply channel communicates with the annular air flow space 300 through the flange ventilation hole 2211. The bottom outlet of the ventilation pipe 22 is lower than the bottom outlet of the combustion control pipe 21 to form a combustion chamber 200. External fresh air enters the air supply channel from the protective net 16, then enters the annular air flow space 300 and then enters the combustion chamber 200, and the flue gas in the combustion chamber 200 enters the moxibustion seat.

[0058] Among them, the combustion control tube 21 matches the radial dimension of the moxa stick 30 and wraps the moxa stick 30. The elastic direction of the elastic sealing ring 213 is the radial expansion and contraction of the inner hole. The inner diameter dimension of the elastic sealing ring 213 is slightly smaller than the inner diameter dimension of the combustion control tube 21. With such a setting, even when the radial dimension of the moxa stick 30 is on the small side and a certain gap is formed with the inner wall of the combustion control tube 21, it is ensured that fresh air will not directly enter and contact the combustion surface through the above gap, affecting the firepower control. The feeding moxa motor 13 of the rotary advancing and retreating moxa mechanism 10 controls the forward / backward rotation of the moxa stick 30 to advance / retreat, thereby controlling the relative position of the combustion surface of the moxa stick 30 and the bottom outlet of the combustion control tube 21, and further adjusting the contact amount between the combustion surface and fresh air, so as to control the combustion firepower of the moxa stick 30.

[0059] Preferably, the combustion control tube 21 further includes a heat preservation sleeve seat 212 and a heat preservation sleeve 211. The bottom outlet of the tubular main body of the combustion control tube 21 is expanded in diameter to form the heat preservation sleeve seat 212. A heat preservation sleeve 211 made of heat preservation material is sleeved inside the heat preservation sleeve seat 212. The radial dimension of the heat preservation sleeve 211 matches the radial dimension of the moxa stick 30 and wraps the moxa stick 30. The bottom outlet of the heat preservation sleeve 211 is lower than the bottom outlet of the tubular main body of the combustion control tube 21 and higher than the bottom outlet of the ventilation tube 22. The space between the bottom outlet of the heat preservation sleeve 211 and the bottom outlet of the ventilation tube 22 forms the combustion chamber 200. The heat preservation sleeve 211 can be made of aluminosilicate with good heat preservation effect, which is used to prevent the heat of the paper on the outer skin of the moxa stick from leaking out and ensure its best combustion effect.

[0060] It should be noted that the structures of the sealing ring seat 214 formed by expanding the diameter of the top inlet of the tubular main body of the combustion control tube 21 and the heat preservation sleeve seat 212 formed by expanding the diameter of the bottom outlet are only for the convenience of describing the installation of the elastic sealing ring 213 and the heat preservation sleeve 211. In specific implementation, the shapes of the elastic sealing ring 213 and the heat preservation sleeve 211 can be in various styles, and the installation methods are also diverse, such as directly sleeving on the tubular main body of the combustion control tube 21 for installation, etc.

[0061] Further, a plurality of skinning knives 25 distributed around the central axis of the combustion control tube 21 are arranged on the inner side wall of the combustion control tube 21 above the heat insulation sleeve 211. The skinning knives 25 are arranged in the radial direction of the combustion control tube 21 to cut the outer wall of the moxa stick 30 (specifically, the outer layer of wrapping paper). Specifically, holes can be opened on the side wall of the combustion control tube 21. The skinning knife 25 is in an L shape. Its vertical part is attached to the outer wall of the combustion control tube 21, and the horizontal part passes through the hole on the side wall of the combustion control tube 21 and extends into the combustion control tube 21. The end of the horizontal part forms a blade. The outer layer of the moxa stick on the market is rolled by paper. The paper is relatively thick and often has more than one layer. During the combustion process of controlling the oxygen supply to the moxa stick, the temperature of the combustion surface is not too high, so that the outer layer of paper cannot be completely burned. However, the ground moxa leaves inside are made of a material that is extremely easy to burn. The skinning knife 25 pre-cuts the outer skin paper into thin strips during the forward and backward rotation of the moxa stick, increasing the flammability of the paper and reducing the difference in flammability between the inner and outer materials. It should be noted that the setting of the skinning knife 25 in the axial position of the combustion control tube 21 is not limited to above the heat insulation sleeve 211. Considering that the outer wrapping paper near the combustion surface of the moxa stick is easier to cut after being scorched by high temperature, and in the subsequent operation control of the combustion control machine, the combustion surface of the moxa stick moves up and down for adjustment at the outlet of the heat insulation sleeve 23. Therefore, the position of the skinning knife 25 can be selected within the outlet of the heat insulation sleeve 211 and the axial length range of the heat insulation sleeve 211 according to needs.

[0062] Further preferably, the ventilation pipe 22 is in the shape of a funnel with a larger upper part and a smaller lower part. The middle part is a conical part, and both the upper and lower parts are cylindrical and connected to the conical part. In this embodiment, the heat insulation sleeve 211 is located within the length range of the conical part. A spiral air guiding piece 24 surrounding the combustion control tube 21 is further arranged between the ventilation pipe 22 and the combustion control tube 21. The air guiding piece 24 is located below the flange 221. The spiral air guiding piece 24 is not necessarily in the shape of a complete circle. It can be understood that only a section is taken from the entire circle. The air guiding piece 24 is located below the flange ventilation hole 2211 and corresponds to it in number and has the same spiral direction. The height of the heat insulation sleeve seat 212 is lower than the height of the air guiding piece 24. The air flow entering the annular air flow space 300 from the air supply channel through the flange ventilation hole 2211 forms a swirling air flow under the guidance of the air guiding piece 24 when entering, and then enters the combustion chamber 200 through the space between the conical part and the combustion control tube 21 and the heat insulation sleeve 211, generating turbulence and mixing with the flue gas in the combustion chamber 200.

[0063] Reference Figure 7, S1 represents the fresh air flow, and S2 represents the turbulent flow of hot flue gas. The fresh air enters the combustion chamber 200 from the annular air flow space 300. Since the hot flue gas in the combustion chamber 200 rises upward while the fresh air flows downward, it drives the flue gas near the burning surface of the moxa stick to generate turbulence and mix with the fresh air during the flow. When the entire burning surface of the moxa stick is inside the heat preservation sleeve 211 and far from the bottom outlet of the heat preservation sleeve 211, the heat preservation sleeve 211 forms an annular protective cover for the upward rising hot flue gas, and it is difficult for the fresh air to enter the hot flue gas of the exchange combustion surface through the turbulence. At this time, the moxa stick burns slowly (even suffocates), which belongs to the low-temperature state. When the moxa stick moves downward, the distance between the burning surface and the bottom outlet of the heat preservation sleeve 211 decreases, and the fresh air exchanges more and more with the hot flue gas of the burning surface through the turbulence, and the burning of the moxa stick gradually accelerates. When the moxa stick continues to move downward and exceeds the bottom outlet of the heat preservation sleeve 211, the outer ring surface of the moxa stick directly contacts the fresh air, and the burning speed of the moxa stick continues to increase. Moreover, at this time, the part of the burning surface of the moxa stick close to the center mixes less fresh air and has a slower burning speed, while the closer to the outer ring surface, the more fresh air is mixed and the faster the burning speed is. The continuous downward movement of the moxa stick makes the burning surface of the moxa stick naturally form a cone, thereby increasing the burning area and doubling the burning heat. At this time, the moxa stick burns rapidly, which belongs to the high-temperature state. Therefore, by adjusting the position of the burning surface of the moxa stick inside and outside the heat preservation sleeve 211, the temperature of the moxa stick burning can be controlled.

[0064] According to the working principle of the above moxa stick combustion control machine, with a moxibustion seat and a controller that can fixedly install the moxa stick combustion control machine, and a temperature sensor line is set at the air outlet of the combustion control machine to feedback the temperature change to the controller, a simplest moxibustion machine can be formed to perform moxibustion on the human body.

[0065] Embodiment 2

[0066] Reference Figure 8-15 , this embodiment is a fixed moxibustion machine, including a moxibustion seat and a moxa stick combustion control machine. In the figure, A represents the moxa stick combustion control machine, specifically referring to Embodiment 1, and B represents the moxibustion seat. In this embodiment, when the moxibustion machine is used, the burning head 20 of the moxa stick combustion control machine is first installed on the moxibustion seat, and the moxibustion seat is installed on the skin to perform moxibustion on the skin. During the moxibustion process, the height between the moxa stick combustion control machine and the moxibustion seat is fixed and immovable.

[0067] Among them, the moxibustion seat includes an ash filtering seat 40, an air flow seat, an ash filtering net 57, and a temperature measuring wire. The ash filtering seat 40 and the air flow seat are both hollow structures with unobstructed upper and lower parts to serve as an air flow passage for air flow. One end of the ash filtering seat 40 is connected to the combustion head 20 of the moxa stick combustion controller, and the other end is connected to the air flow seat. One end of the air flow seat away from the ash filtering seat 40 faces the skin of the moxibustion point. The ash filtering net 57 and the temperature measuring head of the temperature measuring wire are installed between the combustion head 20 and the skin of the moxibustion point. The moxa stick combustion surface of the moxa stick is communicated with the skin of the moxibustion point through the air flow passage of the ash filtering seat 40 and the air flow seat.

[0068] In this embodiment, the air flow seat includes a smoking hood 50 and a diversion seat 60. The ash filtering seat 40 is tightly and fittingly sleeved inside the upper end of the smoking hood 50. The lower part of the smoking hood 50 faces the skin. The lower end of the smoking hood 50 is detachably connected to the diversion seat 60 up and down, specifically by screw connection. The diversion seat 60 is fixed in contact with the human skin, specifically by a binding strap. The diversion seat 60 is generally flat, and can also be made into a shape imitating the moxibustion part of the human body. A pair of oppositely arranged C-shaped rings 66 are connected to the outside of the diversion seat 60, and the binding strap passes through the C-shaped rings 66 to realize the binding of the diversion seat 60 and the moxibustion subject. Of course, the diversion seat 60 can also be adhesively fixed to the skin by installing a sticky object such as double-sided tape at its bottom.

[0069] The ash filtering seat 40 is in a cylindrical shape and includes a cylindrical ash filtering seat inner cavity 41 with unobstructed upper and lower parts. The smoking hood 50 includes a smoking hood inner cavity 51 with unobstructed upper and lower parts, and the smoking hood inner cavity 51 is also a cylindrical channel. The smoking hood 50 further includes an annular air passage 54 and an annular air collection area 52 surrounding the outer peripheral side of the lower part of the smoking hood inner cavity 51. The annular air passage 54 is communicated with the air path of an external exhaust fan through a smoking pipe 56. The annular air passage 54 is located above the annular air collection area 52 and is communicated with the annular air collection area 52 through a plurality of smoking hood through holes 53. The smoking hood through holes 53 extend downward from the bottom of the annular air passage 54 through to the top of the annular air collection area 52. The outer edge bottom of the annular air collection area 52 is open and forms an annular air supplement port 55 communicating with the external environment at a certain height interval from the diversion seat 60. The diversion seat 60 has a diversion seat inner cavity with the upper part communicated with the smoking hood inner cavity 51 and the lower part open to the skin. A circle of ventilation channels 62 extending in the radial direction is opened on the peripheral side of the diversion seat inner cavity. The top of the ventilation channels 62 is open and extends to the lower part of the annular air collection area 52.

[0070] More specifically, the smoking hood 50 includes a concentrically arranged cylindrical main body, a conical side plate, an annular horizontal plate, and a cylindrical outer plate. The height of the cylindrical main body is much smaller than the height of the ash filter base 40, and the outer periphery of the bottom is provided with a thread (for connecting the flow guide base 60). The large diameter of the conical side plate faces downward, the small diameter of the top of the conical side plate is connected to the cylindrical main body, and the large diameter of the bottom of the conical side plate and the top of the cylindrical outer plate are simultaneously connected to the cylindrical main body through the annular horizontal plate. The inner cavity of the smoking hood 51 is formed inside the cylindrical main body. The conical side plate, the annular horizontal plate, and the cylindrical main body enclose to form the annular air passage 54. The cylindrical outer plate, the annular horizontal plate, and the cylindrical main body enclose to form the annular air collection area 52. The through hole 53 of the smoking hood is opened through the annular horizontal plate. The smoking pipe 56 is connected to the conical side plate. The ventilation passage 62 is located within the horizontal projection of the cylindrical outer plate. A protective net 64 covering the opening below the inner cavity 51 of the smoking hood is installed at the bottom of the flow guide base 60. Specifically, a step 641 is formed at the bottom of the flow guide base 60, and the protective net 64 is snapped into the step 641 from the bottom of the flow guide base 60. A circular flow guide base cylindrical connecting sleeve 63 protrudes upward at the top of the flow guide base 60. The flow guide base cylindrical connecting sleeve 63 straddles the upper part of the ventilation passage 62. The horizontal projection of the flow guide base cylindrical connecting sleeve 63 is located in the annular air collection area 52 and the inner cavity of the flow guide base. A thread is provided inside the flow guide base cylindrical connecting sleeve 63 for connecting with the external thread at the lower end of the cylindrical main body. The gap between the cylindrical outer plate and the top of the flow guide base 60 forms the annular air supplement port 55. In this embodiment, the external exhaust fan is set so that the exhaust air volume is slightly larger than the air supply volume for the burning of the moxa stick supplied by the air supply fan 17. The excess air volume is supplemented from the outside through the annular air supplement port 55. In this way, it not only ensures that all the waste smoke is discharged, but also does not affect the stability of the internal air pressure and the moxibustion air flow.

[0071] A heat moxibustion channel 44 extending along the axial direction is provided inside the lower end of the ash filtering seat cavity 41. Specifically, a through hole is opened at the bottom of the ash filtering seat 40, and the edge of the through hole extends upward along the axis to form a cylindrical heat moxibustion channel 44. The hot flue gas in the ash filtering seat cavity 41 enters the smoking hood cavity 51 through the heat moxibustion channel 44. An ash filtering net 57 is provided inside the ash filtering seat cavity 41, which is located below the combustion head 20 and is controlled by a dust shaking motor 512 to shake off the moxa ash. The ash filtering net 57 is located above the heat moxibustion channel 44 and its projection covers the heat moxibustion channel 44. The annular groove between the heat moxibustion channel 44 and the inner side wall of the ash filtering seat cavity 41 serves as an ash storage tank 45 to receive the moxa ash shaken off from the ash filtering net 57. A dust shaking motor cover 48 is installed on the outer side wall of the ash filtering seat 40. The dust shaking motor cover 48 and the outer side wall of the ash filtering seat 40 enclose a dust shaking motor chamber 49, and the dust shaking motor 512 is arranged in the dust shaking motor chamber 49. The outer side wall of the ash filtering seat 40 also opens an ash filtering net installation groove 46 and an ash filtering net through hole 47 within the coverage of the dust shaking motor chamber 49. The ash filtering net through hole 47 penetrates the outer side wall of the ash filtering seat 40 and communicates with the ash filtering seat cavity 41. The ash filtering net 57 includes an ash filtering net frame 573 for installing a filter net body 571, ash filtering net fixing arms 572, elastic ash brushing rods 576, and flexible ash sweeping brushes 575. The ash filtering net frame 573 and the filter net body 571 are inclined and arranged in the ash filtering seat cavity 41. One end of the elastic ash brushing rod 576 is fixed to the ash filtering net frame 573, and the other end is connected to the flexible ash sweeping brush 575. Specifically, the elastic ash brushing rod 576 has a repeatedly folded structure, which can be bent from thin steel wire into a continuous S shape to reduce the change in elastic force after being deformed under pressure. The flexible ash sweeping brush 575 can be bent from multiple extremely thin steel wires into multiple upward semi-circular shapes and is installed below the burning surface of the moxa stick. With such a setting, when the burning surface of the moxa stick rotates downward and contacts the flexible ash sweeping brush 575, according to the situation that the burned moxa ash will fall off when touched, it can sweep away the surface moxa ash without scraping off the burning moxa fluff. One end of the ash filtering net fixing arm 572 is snapped into the ash filtering net installation groove 46 for installation and fixation, and the ash filtering net fixing arm 572 passes through the ash filtering net through hole 47 and is connected to the ash filtering net frame 573. The dust shaking motor 512 is connected to the ash filtering net fixing arm 572 to drive the filter net body 571 to vibrate. The above-mentioned inclined setting of the ash filtering net frame 573 and the filter net body 571 is for the convenience of shaking off the moxa ash. Preferably, the ash filtering net frame 573 can also be set horizontally, and the filter net body 571 can be set as a hemispherical or conical shape bulging upward to facilitate the shaking off of the moxa ash.

[0072] A controller 70 is installed on the outer side wall of the ash filtering base 40. The controller 70 is connected to the moxa stick feeding motor 13 of the rotary advancing and retreating moxa mechanism 10 through an electronic wire. The controller 70 is also connected to a primary temperature sensing wire 59. The temperature measuring head of the primary temperature sensing wire 59 is located inside the cavity 41 of the ash filtering base and above the ash filtering net 57. The controller 70 is used to control the moxa stick feeding motor 13 of the rotary advancing and retreating moxa mechanism 10 in the moxa stick combustion controller according to the temperature measurement result of the primary temperature sensing wire 59, so that the moxa stick 30 advances / retreats, thereby realizing the control of the combustion firepower of the moxa stick 30. The process of the controller 70 controlling the moxa stick feeding motor 13 according to the feedback of the primary temperature sensing wire 59 to realize temperature adjustment is defined as primary temperature adjustment. Secondary temperature adjustment will be involved in the subsequent Embodiments 3 and 4.

[0073] The controller 70 also drives the air blower 17 of the moxa stick combustion controller to supply oxygen and drives an external exhaust fan to extract smoke. The moxa stick feeding motor 13 of the moxa stick combustion controller and the ash vibrating motor 512 of the moxa seat are started with a delay, and the ash vibrating motor 512 works intermittently after the delay start. It should be noted that installing the controller 70 on the outer side wall of the ash filtering base 40 is only a choice of the installation position of the controller 70. For the convenience of the moxa recipient's own control, the controller 70 can also be separated from the moxa seat and the two are connected by an electronic wire of a certain length, which is more convenient for the moxa recipient to adjust the temperature at any time according to his own body sensation.

[0074] A filter ash seat positioning step 402 protrudes from the inner wall of the filter ash seat. Refer to Figure 1 , a combustion controller positioning step 222 that cooperates with the filter ash seat positioning step 402 is formed on the outer wall of the ventilation pipe 22 near its inlet. When the moxa stick combustion controller is inserted into the filter ash seat 40, when the combustion controller positioning step 222 coincides with the filter ash seat positioning step 402, it means that the insertion is in place. When the insertion is in place, the outer wall of the ventilation pipe 22 is in sealed cooperation with the inner wall of the filter ash seat 40.

[0075] Since the parts of the human body that need moxibustion are often unable to reach a horizontal angle, and due to the elasticity of the muscles, although the C-shaped ring of the fixing base of the moxibustion machine is tied with a strap, the body of the moxibustion machine will sink and squeeze the muscles in the lower direction due to gravity, resulting in additional tilting. Therefore, the moxibustion machine of this embodiment further includes an auxiliary support foot assembly 80 with adjustable length and tilting angle, specifically two auxiliary support foot assemblies 80. The auxiliary support foot assembly 80 includes a support rod 81, a support sleeve 82, a support plate 83, etc. An adhesive substance such as double-sided tape can also be provided on the bottom surface of the support plate 83 to prevent sliding with the support point. The support rod 81 is slidably sleeved in the support sleeve 82, and the bottom end of the support rod 81 is hinged to the support plate 83. Specifically, a pair of support plate connecting ears 831 are provided on the top surface of the support plate 83, and the bottom end of the support rod 81 has a connecting ear 812. The connecting ear 812 is located between the pair of support plate connecting ears 831, and the three are connected in series by a horizontally arranged rotating shaft. The top ends of the support sleeves 82 of the two auxiliary support foot assemblies 80 are hinged to the same C-shaped clamp 84 and are clamped to the body of the entire moxibustion base through the C-shaped clamp 84. Specifically, a pair of support sleeve connecting ears 821 are provided on the side wall of the top end of the support sleeve 82, and two clamp connecting ears 841 protrude from the outer side wall of the C-shaped clamp 84. The support sleeve connecting ears 821 are located between the two clamp connecting ears 841, and the three are connected in series by a horizontally arranged rotating shaft. The C-shaped clamp 84 can be conveniently installed and disassembled as needed and can also be rotated along the body to a suitable angle. A support foot positioning boss 401 protrudes radially from the top edge of the ash filter base 40, and the support foot positioning boss 401 abuts against the C-shaped clamp 84 up and down. A row of ratchet teeth 811 is provided on the support rod 81 along its length direction. The function of the ratchet teeth 811 is to lock the sliding of the support rod 81 in the support sleeve 82, so as to realize the support requirements at any height in different positions. A tongue lock 821 that cooperates with the ratchet teeth 811 to achieve locking and can be rotated and opened is installed at the lower end of the support sleeve 82. By locking or opening the tongue lock 821, the sliding of the support rod 81 can be restricted or the restriction can be released. Specifically, the tongue lock 821 is provided with a horizontally extending pin hole 8211. Correspondingly, a corresponding pin hole is also provided at the bottom end notch 820 of the support sleeve 82 and is combined with a pin to form a rotational connection between the tongue lock 821 and the support sleeve 82. A lock tongue 8212 and a handle 8213 are formed by extending the side wall of the tongue lock 821. The lock tongue 8212 and the handle 8213 are generally oppositely arranged. An elastic thin sheet 8214 is provided on the side wall of the tongue lock 821. The end of the elastic thin sheet 8214 forms a certain top pressure with the support sleeve 82, so that the lock tongue 8214 is always in contact with the ratchet teeth 811. As Figure 15As shown, the tooth profile of the ratchet 811 is a one-way setting with the tooth tip facing upward. In this way, when the support rod 81 is pulled downward, the ratchet 811 can push open the locking tongue 8212 to deflect the tongue lock 821 and automatically release the restriction. When the support rod 81 is pulled to the appropriate support length, under the action of the elastic sheet 8214, the locking tongue 8212 automatically locks the ratchet to restrict the upward retraction of the support rod 81. When it is necessary to retract the support rod 81, the tongue lock 821 can be rotated by turning the handle 8213 to overcome the elastic force of the elastic sheet 8214, so as to separate the locking tongue 8212 from the ratchet 811, and the support rod 81 can then retract upward.

[0076] The functions of the entire auxiliary support foot assembly 80 are summarized as follows: The C-shaped clamp 84 solves the selection of the horizontal support angle, that is, it supports the side where the moxibustion machine tilts; the openable connection method between the support sleeve 82 and the C-shaped clamp 84 solves the selection of the vertical support angle, that is, it can be placed at any angle suitable for support; the self-locking function of any length of the support rod 81 solves the need for the total support length change during the opening and closing swing of the support sleeve 82; the rotatable connection between the support plate 83 and the support rod 81 solves the fitting problem of uneven support points. Coupled with the adhesive substance at the bottom of the support plate 83, it can support well even on the outwardly inclined body surface.

[0077] The operation and working principle of this embodiment are as follows:

[0078] 1): Loosen the threaded connection between the combustion control base 11 and the combustion head 20, connect the moxa stick 30 to the moxa stick socket 12 through the pin 1201, and make the moxa stick 30 concentric with the moxa stick socket 12 through the restriction of the thin-walled sleeve 1204, and then light the moxa stick 30.

[0079] 2): Insert the lit moxa stick 30 into the combustion control tube 21, and the insertion depth can be controlled so that the combustion surface of the moxa stick is flush with the lower end surface of the heat preservation sleeve 211, and then tighten the threaded connection between the combustion control base 11 and the combustion head 20.

[0080] 3): Insert the moxa stick combustion controller into the ash filter base 40, making the positioning step 222 of the combustion controller coincide with the ash filter base positioning step 402 of the ash filter base 40 to determine the insertion depth. The outer wall of the ventilation pipe 22 is in sealed cooperation with the inner wall of the ash filter base 40 to seal the air flow. Preset the starting temperature on the controller 70 and start the control. First, drive the air blower 17 to work for air supply and oxygen supply, so that the moxa stick 30 continues to burn. The generated hot air is blown into the cavity of the ash filter base 40 under the action of the air blower 17, and together with the flame of the burning moxa stick 30, heats the primary temperature sensor line 59. When the temperature measured by the primary temperature sensor line 59 is lower than the required set value, the controller 70 drives the moxa stick feeding motor 13 to rotate forward. Due to the limitation of the motor base guide strip 142 and the machine base guide groove 111, the moxa stick feeding motor base 14 can only move axially and cannot rotate radially. The moxa stick feeding motor 13 is fixed to the moxa stick feeding motor base 14, so the motor shaft drives the moxa stick socket 12 and the moxa stick 30 to rotate forward. Due to the threaded fit between the moxa stick socket 12 and the combustion controller base 11, it also moves slowly downward while rotating, and while moving downward, it also pulls the moxa stick feeding motor 13 and the moxa stick feeding motor base 14 to move synchronously. Thus, the moxa stick 30 continuously moves downward during rotation.

[0081] 4): When the burning moxa stick 30 gradually enters the high-temperature combustion state of the moxa stick and gradually approaches the induction head of the primary temperature sensor line 59 during the downward movement, the induction temperature rises. When it reaches the set value, the moxa stick feeding motor 13 stops. When it is higher than the set value, the moxa stick feeding motor 13 rotates reversely and returns to the low-temperature combustion state of the moxa stick. During the entire combustion control process, since the combustion surface of the moxa stick 30 is generally controlled near the outlet of the combustion control pipe 21, and the newly installed moxa stick 30 is relatively long, correspondingly, the moxa stick feeding motor base 14 will also be in a position relatively close to the air blower base 15, that is, at the beginning of use, the retraction space of the moxa stick 30 is relatively limited. During the combustion of the moxa fire, there will be some abnormal situations that cause the temperature to rise sharply (such as just after a piece of moxa ash has fallen), and it is necessary to retract the combustion surface of the moxa stick 30 deep into the combustion control pipe 21 to reduce the induction temperature. At this time, in the case where the retraction space of the moxa stick 30 is limited as described above, during the retraction process, when the moxa stick feeding motor base 14 approaches the flow blocking piece 28, the flow blocking piece 28 covers the motor base ventilation passage 141, quickly reducing or even blocking the air flow, and there is no hot flue gas descending, so that the induction temperature quickly drops to the set value, and the controller 70 controls the moxa stick feeding motor 13 to stop rotating reversely. Conversely, when the temperature drops below the set value, the controller 70 controls the moxa stick feeding motor 13 to rotate forward and drives the moxa stick feeding motor base 14 away from the flow blocking piece 28, thereby opening the motor base ventilation passage 141.

[0082] The above is the automatic temperature adjustment process of the moxa stick combustion controller. Since the temperature control is also involved in the lifting moxibustion machine in the following Embodiments 3 and 4, it is also called the primary temperature adjustment here.

[0083] 5): Since the newly lit moxa stick 30 fails to burn normally, the generated hot air cannot reach the normal state, and there will be no falling of moxa ash. Therefore, in the control program, when the above-mentioned controller 70 is started, the blower 17 of the moxa stick combustion controller is first driven to supply oxygen, and the exhaust fan connected to the moxa seat is used to extract smoke. The moxa delivery motor 13 and the ash vibrating motor 512 are both set to start with a time delay. Also, since the moxa stick rarely produces ash during the combustion process, the ash vibrating motor 512 is set to work intermittently after the time delay start.

[0084] 6): The flow direction of the air current. After the blower 17 is started, the air current enters the cavity between the moxa delivery motor seat 14 and the moxa stick socket 12 through the air passage 141 of the motor seat, then enters the cavity between the moxa stick socket 12 and the combustion head 20 through the air passage 1203 of the moxa stick socket, and then enters the inner cavity of the ventilation pipe 22 through the flange ventilation hole 2211 of the combustion head 20. When entering, it is guided by the air guide piece 24 to form a rotating air current in the cavity, and enters the combustion chamber 200 from the annular air current space 300, generating turbulence and mixing with the flue gas in the combustion chamber 200. Since the hot flue gas rises and the fresh air descends, at this time, the oxygen content in the mixed air below the combustion surface of the moxa stick will be higher the lower it is. Therefore, the lower the combustion surface of the moxa stick is adjusted in the combustion chamber, the greater the combustion firepower will be. After the fresh air is mixed with the flue gas after combustion, it enters the cavity between the ash filtering seat 40 and the combustion head 20. Because the ash vibrating motor cover 48 and the ash filtering seat 40 are sealed, although the ash vibrating motor chamber 49 is connected to the inside of the ash filtering seat 40 through the ash filtering net hole 47, no air current channel is formed. Therefore, the hot flue gas after combustion enters the inner space of the exhaust hood 50 through the hot moxibustion channel 44, then enters the diversion seat 60 and contacts the skin, and performs moxibustion on the skin together with the burning firelight. Then the waste flue gas is discharged through the air passage 62 of the diversion seat 60 and enters the annular gas collection area 52. The smoking pipe 56 is connected to the exhaust pipe of the external exhaust fan, and the waste flue gas is drawn from the annular gas collection area 52 through the smoking hood hole 53 into the annular air passage 54 and then discharged outward.

[0085] Embodiment Three

[0086] Reference Figure 16-17 , compared with Embodiment Two, the main difference in this embodiment is that a tiltable lift 100 is added. Thanks to the tiltable lift 100, in this embodiment, the ash filtering seat 40 can be automatically lifted during the moxibustion process, and the tilt angle of the exhaust hood 50 and the diversion seat 60 can be adjusted accordingly.

[0087] Specifically, the upper end of the smoking hood 50 is sleeved on the outer periphery of the lower end of the ash filtering seat 40, and a sliding seal fit is provided between the ash filtering seat 40 and the smoking hood 50. That is, the outer side wall of the lower part of the ash filtering seat 40 serves as the outer ring sealing surface 403, and the inner side wall of the smoking hood 50 serves as the inner ring sealing surface 501, and the outer ring sealing surface 403 and the inner ring sealing surface 501 are in sliding seal fit. The ash filtering seat 40 can move up and down relative to the smoking hood 50 under the drive of the lifting motor 90. A secondary temperature sensing wire is provided on the protective net 64 (the protective net 64 refers to Embodiment 2 and will not be elaborated here), and its temperature measuring head is located at the center of the protective net 64. The secondary temperature sensing wire is connected to the controller 70. The controller 70 is used to control the lifting motor 90 to drive the ash filtering seat 40 to move up and down relative to the smoking hood 50 according to the temperature measurement result of the secondary temperature sensing wire, so as to quickly change the temperature at the skin moxibustion point to achieve strong stimulation in a short time and realize the pecking moxibustion function. The process of the controller 70 controlling the lifting motor 90 according to the feedback of the secondary temperature sensing wire to achieve temperature adjustment is defined as secondary temperature adjustment.

[0088] Compared with Embodiment 2, the C-shaped ring 66 on the diversion seat 60 is cancelled, and instead, a smoking hood connecting rod 65 is added outside the smoking hood 50 to cooperate with the tilting elevator 100.

[0089] Among them, the tiltable elevator 100 includes a fixed seat 101, a horizontal rotating seat 102, a horizontal flipping seat 103, a lifting screw 104, a lifting block 105, etc. The fixed seat 101 is generally arc-shaped, and a pair of oppositely arranged C-shaped rings 1011 are connected to both sides thereof. A strap is tied through the C-shaped rings 1011 to realize the binding of the fixed seat 101 and the moxibustion object. The top of the fixed seat 101 has a cylindrical steering seat 1012. The bottom of the horizontal rotating seat 102 has a cylindrical horizontal steering shaft 1021. The horizontal steering shaft 1021 is vertically inserted into the steering seat 1012 and can rotate. The top of the horizontal rotating seat 102 has a set of connecting ears 1022. The horizontal flipping seat 103 is generally a strip-shaped structure, and an open C-shaped groove is formed along its length direction, that is, the cross-section of the horizontal flipping seat 103 is C-shaped. The bottom of the horizontal flipping seat 103 has a horizontally extending connecting column 1031. The connecting column 1031 is located between a set of connecting ears 1022, and the three are fixed by bolts, so that the horizontal flipping seat 103 can perform a horizontal flip relative to the horizontal rotating seat 102 on the basis of the horizontal rotating seat 102. After flipping to an appropriate angle, the bolts are locked and fixed. Such a combination can achieve multi-directional and multi-angle adjustment to meet the moxibustion needs of various parts. Obviously, the above fixed seat 101, horizontal rotating seat 102, and horizontal flipping seat 103 are two sets of relatively rotating structures. As long as the structures and connection methods between them are swapped pairwise, an opposite rotating effect can be obtained, that is: the horizontal rotating seat 102 horizontally flips relative to the fixed seat 101; the horizontal flipping seat 103 horizontally rotates relative to the horizontal rotating seat 102. The above rotating structural method can also be selected as needed. It should be noted that in this embodiment, the fixed point of the moxibustion machine is not limited to the surrounding of the moxibustion point, nor is it necessarily limited to the human body. It can also be fixed on a moxibustion bed or other special brackets to perform moxibustion on the side of the human body. Therefore, there are more fixing methods, not limited to strap tying.

[0090] The bottom of the horizontal flipping base 103 also has a lifting motor mounting base 1032. The lifting motor 90 is installed inside the lifting motor mounting base 1032 with its motor shaft facing upward. The lifting screw rod 104 is located in the C-shaped groove of the horizontal flipping base 103 and is connected to the motor shaft of the lifting motor 90 to rotate under the drive of the lifting motor 90. The lifting block 105 is sleeved outside the lifting screw rod 104 and is in threaded cooperation with it. The lifting block 105 holds the upper outer wall of the ash filtering base 40 through a C-shaped hoop 106. Therefore, when the lifting motor 90 works, it can drive the lifting block 105 to rise / fall, thereby driving the ash filtering base 40 to rise / fall. An axially extending lifting guide strip 1051 is also provided on the outer wall of the lifting block 105, and an axially extending lifting guide groove 1033 is provided in the C-shaped groove of the horizontal flipping base 103. The lifting guide strip 1051 is in sliding cooperation with the lifting guide groove 1033. The top of the horizontal flipping base 103 is open. The screw rod seat 107 is buckled on the top opening of the horizontal flipping base 103 and fixed to the opening, and is rotatably connected to the top of the lifting screw rod 104. Correspondingly, there is also a cylindrical step on the top of the lifting screw rod 104 that mates with it. The horizontal flipping base 103 is also connected to the smoking hood connecting rod 65. Their connection method is a sliding connection along the axial direction of the lifting screw rod 104 and a transverse pressing and fixing. Specifically, the smoking hood connecting rod 65 is vertically arranged with its lower end connected to the smoking hood. The side of the top of the smoking hood connecting rod 65 has a C-shaped card slot 651. The bottom of the horizontal flipping base 103 also has a connecting rod mounting base 1034. The connecting rod mounting base 1034 and the C-shaped card slot 651 form a slidable fit from top to bottom. By sliding, the position of the smoking hood 50 relative to the skin can be adjusted, so as to adjust the fitting of the diversion base 60 to the skin, and the fixing is achieved by using the locking nuts 652 on both sides to press the connecting rod mounting base 1034 with screws. It should be noted that the above sliding method of the cooperation between the C-shaped card slot 651 and the connecting rod mounting base 1034 is only one structural method of the specific implementation. There are also many other structural methods to achieve the above-mentioned axial sliding connection and transverse pressing and fixing.

[0091] Preferably, in combination with Figure 9 and Figure 17 , an air leakage port 510 communicating the inner cavity 51 of the smoking hood and the annular air duct 54 is provided on the sealing surface where the smoking hood 50 is hermetically sleeved with the ash filtering base 40.

[0092] Compared with the second embodiment, this embodiment mainly adds a tilting elevator 100 independent of the moxibustion machine in the second embodiment, which has the pecking moxibustion function, and also adds the functions of horizontal rotation and horizontal angle inclination, which is beneficial for fixing on appliances outside the human body (such as a moxibustion bed) and performing moxibustion on parts of the human body where it is inconvenient to fixedly install the moxibustion machine (such as hands, feet, and head).

[0093] Embodiment Four

[0094] Reference Figure 18-22, the purpose of this embodiment is also to realize the lifting of the ash filtering seat 40 and achieve the pecking moxibustion function. However, compared with Embodiment Three, the implementation method of lifting is different. The integrated structure of this embodiment is more convenient to use. In addition, the supporting method of this embodiment refers to Embodiment Two, which also uses structures such as support rods to achieve support and uses a C-shaped clamp to hold the moxibustion seat. The difference is that the position of clamping in Embodiment Two is the ash filtering seat 40, while the position of clamping in this embodiment is the cylindrical extension of the smoking hood 50 mentioned later.

[0095] In this embodiment, the fixing method of the diversion seat 60 is the same as that in Embodiment Two. This embodiment also includes an annular cover 120, a lower tooth ring positioning sleeve 121, an upper tooth ring positioning sleeve 122, a tooth ring nut 123, a motor gear 124, etc. The outer wall of the ash filtering seat 40 is basically covered with external threads, and the position near the bottom end of the outer wall of the ash filtering seat 40 serves as an outer ring sealing surface 403.

[0096] In this embodiment, the height of the smoke hood 50 is much higher than that in the second embodiment. It is equivalent to adding an additional relatively high cylindrical extension part to the upper part of the cylindrical main body of the smoke hood 50 in the second embodiment. The radial dimension of the cylindrical extension part is slightly larger than that of the cylindrical main body part, and a step is formed at the connection position between the two. The lower positioning sleeve 121 of the gear ring is fitted on this step, so its downward movement in the axial direction is restricted. The annular cover 120 is in threaded cooperation with the top of the cylindrical extension part of the smoke hood 50. The bottom end face of the annular cover 120 covers the upper end face of the upper positioning sleeve 122 of the gear ring, restricting its upward movement in the axial direction. The radial dimension of the waist of the annular cover 120 is larger than that of the cylindrical extension part of the smoke hood 50, so as to form a support foot positioning boss 401 to abut against the C-shaped clamp 84 up and down. The gear ring nut 123 is located inside the smoke hood 50. Its axial position is restricted between the lower positioning sleeve 121 and the upper positioning sleeve 122 of the gear ring. Moreover, the radial position of the gear ring nut 123 is also restricted by the lower positioning sleeve 121 and the upper positioning sleeve 122 of the gear ring, and it is in rotational cooperation with both of them. The gear ring nut 123 is also sleeved outside the ash filter seat 40 and is in threaded cooperation with it. An elevator motor mounting seat 92 is provided on the outer wall of the smoke hood 50. The elevator motor 90 is fixed on the elevator motor mounting seat 92 and is protected by the elevator motor cover 91. The motor shaft of the elevator motor 90 faces downward and is connected to the motor gear 124. A window is opened on the side wall of the smoke hood 50. The motor gear 124 meshes with the gear ring nut 123 through the window. Preferably, an axially penetrating elevator guide groove 404 is opened on the outer side wall of the ash filter seat 40, and an elevator guide strip 502 that is in sliding sleeve cooperation with the elevator guide groove 404 is provided on the inner wall of the cylindrical main body part of the smoke hood 50, specifically on the inner ring sealing surface 501. Based on the cooperation between the elevator guide groove 404 and the elevator guide strip 502, the ash filter seat 40 can be restricted to only move up and down and cannot rotate. Of course, the positions of the guide groove 404 and the guide strip 502 can also be interchanged, that is, the guide groove 404 is arranged on the smoke hood 50, and the guide strip 502 is arranged on the ash filter seat 40.

[0097] In Embodiments 2 and 3, the ash vibrating motor 512 is installed outside the ash filtering seat 40. In fact, it can also be installed inside the ash filtering seat 40. In this embodiment, since the inner cavity of the cylindrical extension of the smoking hood 50 must accommodate the entire ash filtering seat 50 and the ash vibrating motor chamber 49, in order to reduce the radial dimension of the smoking hood 50, the ash vibrating motor 512 is installed inside the ash filtering seat 40. Specifically, the installation position of the ash filtering net 57 is adjusted to inside the ash filtering seat 40. An ash filtering net installation groove 46 is axially formed on the inner side wall of the ash filtering seat 40, and the ash filtering net fixing arm 572 is snapped into the ash filtering net installation groove 46 for installation and fixation. The ash vibrating motor 512 is located below the ash filtering net frame 573 and is connected to the ash filtering net frame 573 through a connecting plate 574 to drive the filter net body 571 to vibrate. A vertically arranged heat insulation plate 410 is arranged inside the ash filtering seat 40. A space for arranging the ash vibrating motor 512, i.e., the ash vibrating motor chamber 49, is formed between one side of the heat insulation plate 410 facing away from the heat moxibustion channel 44 of the ash filtering seat 40 and the inner wall of the ash filtering seat 40. The ash filtering net frame 573 is located above the heat insulation plate 410 with a certain gap therebetween. The ash filtering net 57 is also different from that in Embodiment 2. The ash filtering net frame 573 is not a rectangular frame. The area near the ash filtering net fixing arm 572 and where the elastic ash brushing rod 574 is installed forms an arc-shaped contour corresponding to the inner wall of the ash filtering seat 40 and maintaining a certain arc-shaped gap. And this area covers the ash vibrating motor chamber 49 and the heat insulation plate 410 except for the certain arc-shaped gap, and the covering surface also maintains a certain gap with the top of the heat insulation plate 410. Thus, while not affecting the vibration of the filter net body 571, a relatively sealed space is formed for the ash vibrating motor chamber 49. It should be noted that Figure 19 and Figure 22 the elastic ash brushing rod 574 and the flexible ash sweeping brush 575 in Figure 9 and Figure 13 are only a simple expression. The actual specific structure is the same as that in Embodiment 2.

[0098] In addition, the ash filtering seat positioning step 402 is no longer formed on the inner wall of the ash filtering seat 40, but is directly formed by the upper end surface of the ash filtering seat 40 because the inner diameter dimension of the ash filtering seat 40 is smaller than the inner diameter dimension of the annular cover 120. A wire groove 405 extending axially downward from the top is also formed on the inner wall of the ash filtering seat 40, and the primary temperature sensing wire 59 is introduced into the ash filtering seat 40 along the wire groove 405.

[0099] Continue to refer to Figure 1, a cooling air outlet 222 communicating with the outside is provided on the upper side wall of the ventilation pipe 22 of the burner head 20. The cooling air outlet 222 is lower than the flange 221. The unheated part of the air flow in the burner head 20 preferentially enters the ash vibrating motor chamber 49 of the moxibustion seat through the cooling air outlet 222. Correspondingly, a cooling air inlet 412 corresponding to the cooling air outlet 222 is provided on the inner wall of the upper part of the ash filtering seat 40, and a cooling air outlet is provided at the lower part at a position corresponding to the ash vibrating motor chamber 49. The cooling air inlet 412 and the cooling air outlet communicate with each other inside the ash filtering seat 40. The unheated part of the air flow in the burner head 20 preferentially enters the cooling air inlet 412 through the cooling air outlet 222, flows to the ash vibrating motor chamber 49, and flows to the inner cavity 41 of the ash filtering seat through the gap between the ash vibrating motor chamber 49 and the ash filtering net frame 573, so that the ash vibrating motor chamber 49 continuously has the circulation of cold air, and the ash vibrating chamber 49 maintains a relatively low temperature environment, avoiding the high temperature in the inner cavity 41 of the ash filtering seat from affecting the operation of the ash vibrating motor 512.

[0100] Operations and controls of Embodiment 3 and Embodiment 4: The operations are the same as those of the fixed moxibustion machine in Embodiment 2. In terms of control, the high temperature value and low temperature value of the secondary temperature adjustment are set, as well as the holding time of the high temperature value and the holding time of the low temperature value. And the operation of the secondary automatic temperature adjustment is set to start after the primary temperature adjustment detects that the temperature reaches the normal value. When the secondary temperature sensing wire detects that the temperature is lower than the set value, the lifting motor 90 rotates forward to drive the motor gear 124, and the motor gear 124 drives the engaged ring nut 123 to rotate. Due to the cooperation of the lifting guide groove 404 and the lifting guide bar 502, the ash filtering seat 40 can only move up and down and cannot rotate. And the ring nut 123 is axially and radially positioned between the ring gear lower positioning sleeve 121 and the ring gear upper positioning sleeve 122. Therefore, the rotation of the ring nut 123 will drive the ash filtering seat 40 to move downward through the thread, approaching the moxibustion point. Stop when the detected temperature reaches the set value and enter the high temperature holding timing. During the high temperature holding timing, if the temperature changes, when it is detected that the temperature is lower than the set value, continue to drive the lifting motor 90 to rotate forward to make the ash filtering seat 40 continue to move downward; if it is detected that the temperature is higher than the set value, drive the lifting motor 90 to rotate in the reverse direction to make the ash filtering seat 40 move upward. After the high temperature holding timing ends, drive the lifting motor 90 to rotate in the reverse direction to make the ash filtering seat 40 move upward, away from the moxibustion point. When the secondary temperature sensing wire detects that the temperature reaches the low temperature value, the lifting motor 90 stops and enters the low temperature holding timing. During the low temperature holding timing, if the temperature changes, repeat the same control of the up and down movement of the ash filtering seat 40 as in the high temperature holding timing. After the low temperature timing ends, drive the lifting motor 90 to rotate forward and repeat the control at the beginning, and so on in a cycle until the moxibustion ends.

[0101] Airflow directions in Embodiments Three and Four: Before the flue gas enters the smoking hood 50 from the heat moxibustion channel 44 of the ash filter base 40, the working mode and airflow direction are basically the same as those of the fixed moxibustion machine in Embodiment Two. The airflow direction after the flue gas leaves through the ventilation channel 62 from the internal space of the above-mentioned diversion base 60 is also the same as that of the fixed moxibustion machine in Embodiment Two. Therefore, the same parts will not be elaborated, and only the differences will be described. (1) When the flue gas enters the internal space of the smoking hood 50 from the heat moxibustion channel 44, there are two cases where the ash filter base 40 is at a high position and a low position relative to the axial space of the smoking hood 50. When the ash filter base 40 is at a high position, the open area of the air release port 510 is large. Due to the principle of hot air rising, the relatively hot flue gas just entering from the heat moxibustion channel 44 stays in the upper part. Also, due to the external exhaust, a negative pressure is formed in the annular air channel 54. Most or all of the hot flue gas is directly discharged outward through the air release port 510 and the annular air channel 54. At this time, little or no hot air flow contacts the skin downward, and the secondary temperature sensing wire detects a temperature lower than the set value. According to the control setting, the controller 70 drives the lifting motor 90 to move the ash filter base 40 downward. During the downward movement of the ash filter base 40, the area of the air release port 510 gradually becomes smaller or even completely closed, and the hot flue gas discharged outward through the air release port 510 also gradually decreases. Instead, the hot flue gas is discharged outward through the ventilation channel 62 and gradually increases. This is the airflow situation when the ash filter base 40 is at a low position. As the downward hot flue gas increases and the moxibustion fire approaches, the temperature detected by the secondary temperature sensing wire also continuously rises until it reaches the set value and then stops. When the controller 70 drives the lifting motor 90 to move the ash filter base 40 upward, a reverse effect is obtained. (2) Compared with Embodiments Two and Three, due to the structural characteristics of the lifting moxibustion machine in this embodiment, the body will be slightly larger. To optimize the miniaturization of the structure, the ash shaking motor 512 of the ash filter net 57 is changed from being installed outside the ash filter base 40 to inside. And the inside belongs to a high-temperature area. Currently, the micro ash shaking motors on the market are all permanent magnet structures, and the demagnetization caused by high temperature will damage the motor, so it is necessary to improve the high-temperature working environment of the motor. For this reason, a heat insulation plate 410 is added to the ash filter base 40 to separate the high-temperature flue gas to form a relatively low-temperature ash shaking motor chamber 49. Also, a cooling air inlet 412 is opened on the inner wall of the upper part of the ash filter base 40, and a corresponding cooling air outlet is opened at the lower part, and the upper and lower openings are connected inside. The cooling air inlet 412 corresponds to the cooling air outlet of the burner head 30.Due to the structural arrangement of the combustion chamber in the above-mentioned burner head, during the working state, the hot flue gas naturally rises, and due to the narrowing of the annular air outlet in the burner head, the air pressure in the annular air flow space 300 in the burner head increases relative to the inner cavity 41 of the ash filter seat. Therefore, the unheated air flow in the annular air flow space 300 will preferentially enter the cooling air inlet 412 of the ash filter seat 40 through the cooling air outlet 222 (the flow rate can be controlled by the size of the inlet and outlet), and flow towards the ash vibrating motor chamber 49. Since the arc-shaped mating contour is provided on the ash filter screen 57, it forms a mating with a certain gap with the inner wall of the ash filter seat 40, and forms a mating with a certain gap with the top of the heat insulation plate 410 at the bottom, so that while not affecting the vibration of the ash filter screen 57, the ash vibrating motor chamber 49 forms a relatively sealed space, and the continuous cold air flows from the ash vibrating motor chamber 49 to the inner cavity 41 of the ash filter seat, and the hot flue gas cannot invade in the reverse direction, keeping the ash vibrating chamber 49 in a relatively low-temperature environment and preventing the high temperature in the inner cavity 41 of the ash filter seat from affecting the operation of the ash vibrating motor 512.

[0102] In summary, the moxa stick combustion control machine and moxibustion machine of the present utility model have the following beneficial effects: The moxibustion machine of the present utility model is composed of a moxa stick combustion control machine responsible for controlling the combustion of the moxa stick and a moxibustion seat responsible for solving the problems of ash and flue gas treatment generated during the installation and moxibustion process of the moxa stick combustion control machine. The moxa stick combustion control machine includes a combustion control tube and a ventilation tube. The ventilation tube is sleeved outside the combustion control tube, and an annular air flow space communicating with the air supply channel is formed between the two. When the moxa stick combustion control machine is installed on the moxibustion seat, external fresh air enters the annular air flow space from the air supply channel and then enters the combustion chamber. The flue gas in the combustion chamber is sent to the moxibustion seat for moxibustion. The combustion control tube wraps the moxa stick, and by controlling the advancement / retreat of the moxa stick, the relative position between the combustion surface of the moxa stick and the bottom outlet of the combustion control tube is controlled, so as to adjust the contact amount between the combustion surface of the moxa stick and fresh air, thereby realizing the control of the combustion firepower of the moxa stick, and thus obtaining a controllable and stable moxibustion heat source. The present utility model uses a clever mechanical structure, adopts an active air supply, a structure for rotating and advancing / retreating the moxa stick and the burner head to perfectly realize the controllable combustion of the moxa stick. The various moxibustion seat structures solve the problem of ash removal after the moxa stick burns, and realize the overall miniaturization while having various moxibustion functions, making it possible to open up a broad market for the moxibustion machine.
