Description

Technical Field

[0001] The present invention relates to the technical field of moxibustion therapy equipment, and in particular to a moxibustion device and a moxibustion system. Background Art

[0002] In moxibustion therapy, there's a long-standing saying that moxibustion is ineffective without smoke. The smoke produced by moxibustion is unavoidable, as moxibustion is ineffective without moxa, fire, and smoke. Only with moxa, fire, and smoke can it be considered true moxibustion. Moxibustion smoke (the smoke produced by burning moxa sticks) can enhance the efficacy of moxibustion. Therefore, for moxibustion to be effective, two key factors are crucial: reaching a certain temperature and ensuring that the smoke reaches the skin.

[0003] During moxibustion, moxa sticks are typically burned inside a moxibustion device (also known as a moxibustion box). The device is positioned over the patient's skin (or acupuncture points). The heat from the burning moxa stick warms the acupuncture points, while the smoke from the burning moxa stick contacts the skin at the acupuncture points, achieving a therapeutic effect. With traditional moxibustion devices, the smoke from the burning moxa sticks spreads throughout the treatment, creating a smoky and flaming scene and polluting the environment and air. In order to solve the shortcomings of traditional moxibustion devices, the prior art discloses some smokeless moxibustion systems, which usually include a smoking device and a moxibustion device. The existing moxibustion device is usually equipped with a combustion chamber for burning moxa sticks, and the smoking device can usually generate negative pressure. The smoking device is also connected to the combustion chamber so as to utilize the negative pressure to absorb the generated smoke. In actual use, the shell of the existing moxibustion device usually needs to contact the patient's skin (that is, usually placed directly on the patient's skin) and cover the area to be moxibustioned so as to utilize the patient's skin to seal the lower end of the shell, thereby forming a relatively closed combustion chamber. During moxibustion, the moxa stick burns in the combustion chamber, and there is a certain distance between the burning position of the moxa stick and the skin. At the same time, the smoke generated by the burning moxa stick can be absorbed by the smoking device in the combustion chamber. Although this smokeless moxibustion system is beneficial to preventing the smoke from spreading everywhere, it is found in actual application that these existing smokeless moxibustion systems usually have a problem. There are some deficiencies, for example, 1. the moxa stick burns in the combustion chamber of the moxibustion device, and the moxibustion device is covered on the skin. For example, Chinese patent CN108635211A discloses an automatic temperature-controlled smokeless moxibustion device, so that during the actual moxibustion process, the user cannot see the moxa smoke in the combustion chamber (even if a transparent shell is used, it will be blackened after one use, and the internal situation cannot be seen from the outside). Not only is it difficult to ensure that the moxa smoke acts on the patient's skin, seriously affecting the treatment effect, but it is also inconvenient for the user to understand the moxibustion situation; 2. Since the combustion chamber is directly connected to the smoking device, during the actual moxibustion process, a large part of the moxa smoke is directly sucked away from the back of the moxibustion device, and the moxa smoke does not reach the skin at all, which will also seriously affect the treatment effect; therefore, for different moxibustion occasions, how to prevent the moxa smoke from spreading everywhere while ensuring that more moxa smoke can contact the patient's skin to further improve the treatment effect remains to be solved. Summary of the Invention

[0004] In order to solve the above technical problems, a non-contact moxibustion device is provided. Not only does it not require direct contact with the patient's skin during the moxibustion process, and the situation of the moxa smoke can be seen intuitively, but the size of the smoking port and the position of the negative pressure area can be adjusted according to actual conditions, thereby effectively preventing the moxa smoke from escaping while ensuring that more moxa smoke can contact the patient's skin, achieving better treatment effects.

[0005] A moxibustion device comprises an inner component, an outer shell, a reset spring and an adjusting member, wherein the inner component comprises a pusher and an inner shell with a combustion chamber, the lower end of the inner shell is provided with a moxibustion port, smoke in the combustion chamber is released outwards through the moxibustion port, and the outer surface of the inner shell gradually shrinks inwards along the direction from the lower end to the upper end of the inner shell; the pusher comprises a pushing mechanism for pushing the moxa stick, the pushing mechanism comprises a guide cylinder adapted for the moxa stick, the guide cylinder is vertically connected to the inner shell and communicated with the combustion chamber, the upper end of the guide cylinder is closed, and the guide cylinder is provided with an external thread; the upper end of the outer shell is provided with a through hole, and the lower end of the outer shell is provided with a hole for the inner shell to be raised and lowered The outer shell is sleeved on the guide cylinder through the through hole and covers at least the upper part of the inner shell through the adapter; the reset spring is sleeved on the guide cylinder, and the upper and lower ends of the reset spring respectively abut against the outer shell and the inner shell; the adjusting piece is threadedly connected to the guide cylinder, and the outer shell abuts against the adjusting piece under the elastic force of the reset spring; an inner cavity is formed between the outer shell and the inner shell, and a ring-shaped smoking port is formed between the inner surface of the lower end of the outer shell and the outer surface of the lower end of the inner shell, the smoking port is connected to the inner cavity, and the inner cavity is connected to the negative pressure joint; the adjusting piece is used to drive the outer shell to move relative to the inner shell to adjust the size of the smoking port and the position of the negative pressure area. This technical solution constructs a combustion chamber in the inner shell, and constructs a moxibustion port at the lower end of the inner shell, and at the same time closes the upper end of the guide cylinder connected to the combustion chamber, so that the top of the combustion chamber is in a closed state, and the moxibustion smoke generated in the combustion chamber can only be discharged downward through the moxibustion port so as to flow toward the patient's skin, which is beneficial for the moxibustion smoke to contact the patient's skin and convenient for the user to intuitively check the condition of the moxibustion smoke; by configuring the outer shell and the inner shell, and constructing the moxibustion port at the lower end of the inner shell, and constructing the adapter port at the lower end of the outer shell, and making the outer shell cover at least the upper part of the inner shell, so that an inner cavity can be formed between the outer shell and the inner shell, and a ring-shaped smoking port is formed between the inner surface of the lower end of the outer shell and the outer surface of the lower end of the inner shell, the smoking port is connected to the inner cavity, and the inner cavity is connected to the negative pressure joint, so that a ring can be formed on the outside of the moxibustion port. shaped, with negative pressure smoking port, so as to capture the moxa smoke escaping outward along the circumferential direction of the moxibustion port to prevent the moxa smoke from spreading everywhere; through the cooperation of the guide cylinder, the adjustment part, the reset spring device and the outer shell, the inner shell has the freedom to rise and fall vertically relative to the outer shell, and the adjustment part can be used to drive the inner shell to move relative to the outer shell. It is not only simple and convenient to operate, but also the size of the smoking port and the position of the negative pressure area can be synchronously adjusted by the adjustment part, so that the distance between the moxibustion port and the skin, the size of the smoking port and the position of the negative pressure area can be adjusted according to actual conditions, so that the moxibustion device does not directly contact the patient's skin, while the moxibustion smoke discharged from the moxibustion port can contact the skin as much as possible, and finally be completely sucked away by the negative pressure in the negative pressure area, so that better treatment effect can be achieved while the moxibustion smoke is visible and cannot escape.

[0006] Preferably, the pusher further comprises a limiting structure adapted for the moxa stick, the limiting structure being arranged in the combustion chamber and being used to limit the falling of the moxa stick in the guide cylinder; the pushing mechanism further comprises a pushing spring and a cover component adapted for the guide cylinder, the cover component being detachably connected to the upper end of the guide cylinder; the pushing spring is placed in the guide cylinder, the upper end of the pushing spring being used to abut against the cover component, and the lower end of the pushing spring being used to abut against the moxa stick. The limiting structure cooperates with the pushing mechanism and serves to limit the pushed moxa stick, so that during the burning process of the moxa stick, the elastic force of the pushing spring is gradually released synchronously, ensuring that the lower end of the moxa stick is always pressed against the limiting structure, thereby ensuring that the position of the burning end of the moxa stick remains substantially unchanged, which is not only conducive to achieving a better moxibustion effect, but also the structure of the pusher is very simple, can effectively reduce costs, and is more stable and reliable.

[0007] Preferably, the inner shell adopts a semi-elliptical or semi-circular structure. This not only makes the thickness of the inner shell uniform, which is more convenient for molding and manufacturing, but also makes the outer surface of the inner shell an arc surface inclined to the vertical direction rather than a flat surface, which facilitates adjusting the size of the smoking port and the position of the negative pressure area by changing the relative position of the inner shell and the outer shell.

[0008] Preferably, the moxibustion port is a circular hole; the adapter port is a circular hole, and the inner diameter of the adapter port is larger than the outer diameter of the moxibustion port, so as to form a circular smoking port and evenly distribute the negative pressure.

[0009] Furthermore, the invention also includes a bottom cover, which is structured with a mesh port, and an ash screen is provided inside the mesh port. The bottom cover is detachably mounted on the lower end of the inner shell, and the ash screen covers the moxibustion port, which can effectively prevent the user from being burned by ash.

[0010] Preferably, the outer shell comprises an inner cylinder, an outer cylinder, and a top cover. The inner cylinder is cylindrical and disposed within the outer cylinder. The outer cylinder is cylindrical and coaxial with the inner cylinder. The through hole is formed in the top cover and is coaxial with the inner cylinder. The top cover is connected to the outer cylinder to seal the upper end of the outer cylinder. The inner diameter of the outer cylinder is greater than the maximum outer diameter of the inner shell. The central channel of the inner cylinder is configured to accommodate a guide cylinder, which is sleeved within the guide cylinder and forms a vertically movable pair. A return spring is sleeved on the outer side of the inner cylinder, and the inner shell is located below the inner cylinder. This can solve the problem of improving the relative movement stability between the inner and outer shells.

[0011] Furthermore, the guide cylinder includes a lower cylinder connected to the inner shell and an upper cylinder connected to the lower cylinder, the inner diameter of the lower cylinder is the same as the inner diameter of the upper cylinder, and is larger than the outer diameter of the moxa stick; the outer contour of the upper cylinder is cylindrical, the external thread is constructed on the upper cylinder, and the outer contour of the lower cylinder is square cylindrical; the central channel of the inner cylinder is constructed as a stepped hole, the stepped hole includes a cylindrical channel section adapted to the upper cylinder and a square column channel section adapted to the lower cylinder; the upper cylinder is inserted into the cylindrical channel section, and the lower cylinder is inserted into the square column channel section. In this solution, through the cooperation of the upper cylinder and the cylindrical channel section, the two only constitute a moving pair, ensuring that the outer shell moves strictly vertically relative to the inner shell; through the cooperation of the lower cylinder and the square column channel section, the two can not only constitute a moving pair, but also effectively prevent relative rotation, so that the outer shell can only move relative to the inner shell but cannot rotate relative to it. When in use, the relative position of the inner shell and the outer shell can be effectively adjusted by rotating the adjusting piece with one hand, and the guide cylinder will not rotate with the adjusting piece. It is very convenient to use and can solve the problem of completing the adjustment work with one hand.

[0012] Furthermore, the device further includes an exhaust pipe, one end of which is connected to the outer shell and communicates with the inner cavity, and the other end of which is connected to the negative pressure connector. The exhaust pipe is also provided with a regulating valve for adjusting the negative pressure. This allows the negative pressure of each moxibustion device to be adjustable to accommodate different sized inhalation ports and different negative pressure areas. This not only makes it more convenient to use, but also allows for more precise and rapid adjustment of the smoke area, allowing more smoke to contact the skin, thereby achieving a better moxibustion effect. This solves the problem of more precise and rapid adjustment of the smoke area.

[0013] Furthermore, a first equalizing plate and a second equalizing plate are provided in the outer shell, the first equalizing plate is constructed as an annular structure, the inner ring of the first equalizing plate is connected to the inner cylinder, the outer ring of the first equalizing plate is connected to the outer cylinder, the top cover, the first equalizing plate, the outer cylinder and the inner cylinder together form a first equalizing chamber, and the negative pressure joint is connected to the first equalizing chamber; the first equalizing plate is constructed with a first vent array, the first vent array includes a plurality of first vents uniformly distributed along the circumferential direction of the inner ring, each first vent is respectively connected to the first equalizing chamber, and the cross-sectional area of ​​the exhaust pipe is greater than the sum of the cross-sectional areas of the first vents; the second equalizing plate is constructed as an annular structure, the second The inner ring of the equalizing plate is connected to the inner cylinder, the outer ring of the second equalizing plate is connected to the outer cylinder, the second equalizing plate is arranged below the first equalizing plate, and the first equalizing plate, the second equalizing plate, the outer cylinder and the inner cylinder together form a second equalizing chamber; each first vent is connected to the second equalizing chamber respectively; the second equalizing plate is constructed with a second vent array, the second vent array includes a plurality of second vents evenly distributed along the circumference of the inner ring, each second vent is connected to the second equalizing chamber respectively, the second equalizing chamber is connected to the smoking port below through each second vent, and the sum of the cross-sectional areas of each first vent is greater than the sum of the cross-sectional areas of each second vent. This is conducive to a more even distribution of negative pressure along the circumference of the moxibustion port, effectively preventing moxa smoke from escaping, and can solve the problem of preventing smoke from escaping around the moxibustion port.

[0014] Furthermore, multiple partitions are provided within the outer shell. The upper ends of the partitions are connected to the second equalizing plate, and the outer ends of the partitions are connected to the outer cylinder. The partitions are arranged vertically along the radial direction of the outer cylinder, with the inner ends of the partitions extending toward the inner cylinder and the lower ends of the partitions extending to the lower end of the outer cylinder. The partitions are configured to conform to the outer contour of the inner shell. The partitions are evenly distributed along the circumference of the outer cylinder, thereby circumferentially dividing the space below the second equalizing plate into multiple zones, preventing interference between the zones. This facilitates obtaining a more evenly distributed negative pressure along the circumference of the inhalation port, thereby achieving better smoking and moxibustion effects.

[0015] Furthermore, the partition plate is made of a corrugated plate, and the folds of the corrugated plate are distributed in the horizontal direction. This makes the surface of the partition plate present an uneven structure from bottom to top, so that during the process of transporting the smoke, most of the mugwort oil contained in the smoke can be retained on the surface of the partition plate, thereby effectively removing most of the mugwort oil in the smoke before the smoke enters the subsequent pipeline, effectively reducing the oil content in the smoke, and thus effectively protecting the downstream pipelines and negative pressure equipment, greatly increasing the cleaning cycle of the pipelines and negative pressure equipment, facilitating longer stable operation, and solving the problem of preventing the mugwort oil from being easily inhaled into the downstream pipelines and negative pressure equipment, causing contamination and difficulty in cleaning.

[0016] Furthermore, it also includes a replaceable suction nozzle, which is constructed as an annular structure that fits the outer tube, with a threaded hole on the upper part of the suction nozzle, and an external thread that fits the threaded hole on the lower end of the outer tube. The suction nozzle is threadedly connected to the lower end of the outer tube; a guide surface for guiding smoke is constructed below the threaded hole in the suction nozzle, and the guide surface is an inward-curved arc surface or an outward-curved arc surface. Users can choose to install or remove the suction nozzle of the corresponding structure according to actual needs, which is not only more flexible to use, but also can adjust the range of moxibustion or the range of smoke adsorption over a wider range, thereby meeting more usage occasions, being more versatile, and being able to solve the problem of adjusting the range of the negative pressure area over a wider range.

[0017] Furthermore, the device further comprises a sealing cap having an internal thread; the lower end of the outer tube has an external thread adapted to the internal thread; the sealing cap is threadedly connected to the lower end of the outer tube, sealing the combustion chamber and the inner cavity, and the combustion chamber is connected to the inner cavity via the moxibustion port; an air inlet is also formed on the side of the guide tube, the air inlet is connected to the combustion chamber via the guide tube, and a sealing plug is provided at the air inlet. This can solve the problem of moxa smoke spreading everywhere when the user stops moxibustion midway.

[0018] A moxibustion system includes the moxibustion device, a bracket, and a negative pressure system. The negative pressure system includes a negative pressure device for generating negative pressure and a pipeline. The housing is fixed to the bracket, and the negative pressure connector is connected to the negative pressure device via the pipeline. The negative pressure system generates negative pressure at the smoking port of the moxibustion device, thereby continuously absorbing smoke generated during the moxibustion process, thereby achieving the purpose of smokeless moxibustion.

[0019] In order to solve the problem of removing the moxa oil contained in the smoke, further, the pipeline adopts a corrugated tube.

[0020] Compared with the existing technology, the moxibustion device and moxibustion system provided by the present invention not only do not require direct contact with the patient's skin during the moxibustion process, so that the moxa smoke can be seen more intuitively, but also can adjust the size of the smoking port and the position of the negative pressure area according to actual conditions, thereby effectively preventing the moxa smoke from escaping while ensuring that more moxa smoke can reach the patient's skin, achieving better and more stable moxibustion treatment effects.

DETAILED DESCRIPTION

[0042] Example 1:

[0043] This embodiment provides a moxibustion device, including an inner component, an outer shell 3, a negative pressure connector 54 and a reset spring 51. The inner component includes an inner shell 1 and a pusher connected to the top of the inner shell 1. A combustion chamber 11 is constructed in the inner shell 1. Figure 1 and Figure 2 As shown, the lower end of the inner shell 1 is configured with a moxibustion port 12 connected to the combustion chamber 11, and the upper end of the inner shell 1 is configured with an opening connected to the combustion chamber 11, as shown in FIG. Figure 1 and Figure 2 As shown, the pusher is connected to the combustion chamber 11 through an opening, and the top of the pusher is closed. The combustion chamber 11 is mainly used to provide a relatively closed place for the combustion of the moxa stick 91 to prevent the smoke or heat generated by the burning of the moxa stick 91 from spreading to the sides and upwards.

[0044] Since the pusher is connected to the combustion chamber 11 through the opening, the pusher can be used to automatically push the moxa stick 91 to the preset position in the combustion chamber 11, ensuring that the lower end of the moxa stick 91 always remains at the preset position during the moxibustion process; since the lower end of the moxa stick 91 is the burning end, the position of the burning end of the moxa stick 91 always remains unchanged during the moxibustion process, thereby ensuring that the distance between the burning end of the moxa stick 91 and the skin 93 remains consistent during the moxibustion process, thereby facilitating improving the therapeutic effect of moxibustion. In implementation, the pusher can adopt a pusher disclosed in the prior art, such as a spiral pusher. In this embodiment, the pusher includes a pushing mechanism for pushing the moxa stick 91 and a limiting structure 13 adapted to the moxa stick 91. The limiting structure 13 is mainly used to limit the moxa stick 91; the limiting structure 13 and the pushing mechanism can cooperate with each other. During use, the pushing mechanism can automatically push the moxa stick 91 to the preset position in the combustion chamber 11. At the same time, the limiting structure 13 can limit the pushed moxa stick 91, so that the lower end of the moxa stick 91 can always remain at the preset position.

[0045] like Figure 1 and Figure 2 As shown, the pushing mechanism includes a guide cylinder 2 adapted to the moxa stick 91, a cover component 24 adapted to the guide cylinder 2, and a pushing spring 25 adapted to the guide cylinder 2. The lower end of the guide cylinder 2 is connected to the inner shell 1 and is connected to the combustion chamber 11 through the opening at the top of the inner shell 1; the limiting structure 13 is arranged in the inner shell 1 and adapted to the position of the moxa stick 91; the inner diameter of the guide cylinder 2 is larger than the outer diameter of the moxa stick 91; when in use, the moxa stick 91 is placed in the guide cylinder 2, and the lower end of the moxa stick 91 abuts against the limiting structure 13, as shown in FIG. Figure 2 and Figure 6 As shown, the push spring 25 is arranged in the guide tube 2, and the lower end of the push spring 25 abuts against the moxa stick 91 in the guide tube 2, as shown in FIG. Figure 5 and Figure 6 As shown, the upper end of the push spring 25 abuts against the cover member 24, and the cover member 24 is detachably mounted on the upper end of the guide cylinder 2 by a thread to prevent smoke from escaping from the upper end of the guide cylinder 2. At this time, the push spring 25 is in a compressed state, so that the lower end of the moxa stick 91 is pressed tightly against the limiting structure 13. During use, the lower end of the moxa stick 91 is ignited, and the lower end of the moxa stick 91 continuously burns and consumes, causing the moxa stick 91 to gradually become shorter. During this process, the elastic force of the push spring 25 is synchronously and gradually released, ensuring that the lower end of the moxa stick 91 is always pressed tightly against the limiting structure 13, thereby ensuring that the position of the burning end of the moxa stick 91 remains basically unchanged. Not only can a better moxibustion effect be achieved, but the structure of this pusher is very simple, and compared with using a sensor to realize the automatic pushing function, the cost is significantly reduced, and it is more stable and reliable.

[0046] like Figure 2As shown, the lower end of the inner shell 1 forms a moxibustion port 12, the opening is directly opposite to the moxibustion port 12, and a combustion chamber 11 is formed in the inner shell 1. Figure 2 and Figure 6 As shown, the combustion chamber 11 can adopt a truncated cone or cylindrical structure. Along the direction from the lower end to the upper end of the inner shell 1, the outer surface of the inner shell 1 gradually shrinks inward. For example, the entire inner shell 1 can be constructed into a semi-elliptical structure or a semi-circular structure, as shown in FIG. Figure 1 or Figure 2 As shown, not only does the thickness of the inner shell 1 become uniform, but the outer surface of the inner shell 1 also becomes an inclined surface or an arc surface inclined to the vertical direction, rather than a flat surface. When the inner shell 1 is configured as a semi-elliptical structure, the inner and outer surfaces of the inner shell 1 are preferably configured as parabolic surfaces.

[0047] In practice, the limiting structure 13 may include a number of blocks, bars, claws, etc., such as Figure 2 、 Figure 6 、 Figure 8 and Figure 9 As shown, it is only necessary to limit the moxa stick 91 and prevent it from moving further downward under the action of the push spring 25. In practice, the cover member 24 can be connected to the upper end of the guide cylinder 2 by a thread, or can be connected to the guide cylinder 2 by fasteners such as bolts or screws. In practice, a sealing gasket is further provided between the cover member 24 and the guide cylinder 2 to achieve a better sealing effect.

[0048] The lower end of the shell 3 is constructed with an adapter port 33 that adapts to the moxibustion port 12. During implementation, the shape of the adapter port 33 adapts to the shape of the moxibustion port 12. For example, when the moxibustion port 12 adopts a round hole, the adapter port 33 also preferably adopts a round hole. When the moxibustion port 12 adopts a square hole, the adapter port 33 also preferably adopts a square hole to facilitate assembly and mutual cooperation.

[0049] In practice, the housing 3 includes an inner tube 31, an outer tube 32 and a top cover 34. The inner tube 31 and the outer tube 32 can each adopt a cylindrical structure, such as Figure 3 and Figure 4 As shown, the outer shell 3 may be a cylindrical or square cylinder. For example, the inner cylinder 31 and the outer cylinder 32 are both cylindrical. The inner cylinder 31 is disposed inside the outer cylinder 32, and the inner cylinder 31 and the outer cylinder 32 are coaxial. As shown in the figure, the upper end of the inner cylinder 31 is flush with the upper end of the outer cylinder 32. In one embodiment, a top cover 34 can be fixedly connected to the upper ends of the inner cylinder 31 and the outer cylinder 32 to close the top of the entire outer shell 3. In another embodiment, the top cover 34 can be removably mounted on the upper end of the outer cylinder 32. For example, the top cover 34 can be removably connected to the upper end of the outer cylinder 32 via a threaded connection, fasteners, a snap connection, etc. to close the top of the entire outer shell 3. In this embodiment, the inner diameter of the outer cylinder 32 is greater than the maximum outer diameter of the inner shell 1 (i.e., the outer diameter of the lower end of the inner shell 1) to facilitate the storage of the inner shell 1 within the outer cylinder 32.

[0050] The top cover 34 is configured with a through hole 35 adapted to fit the guide cylinder 2 in the pusher. Figure 4 As shown, after the top cover 34 is covered, the upper end of the guide tube 2 can extend outside the top cover 34 through the through hole 35 so that the cover component 24 can be opened and closed separately. A new moxa stick 91 can be replaced without opening the top cover 34, which is more convenient to use.

[0051] In this embodiment, the central channel of the inner cylinder 31 is configured to fit the guide cylinder 2, so that the guide cylinder 2 can be inserted into the inner cylinder 31, and the upper end of the guide cylinder 2 can pass through the upper end of the inner cylinder 31 and extend out of the outer shell 3 through the through hole 35; the guide cylinder 2 and the inner cylinder 31 form a moving pair in the vertical direction, so that the outer shell 3 can move in the vertical direction relative to the guide cylinder 2. Figure 1 As shown, the upper portion of the guide cylinder 2 is configured with an external thread 26, and accordingly, an adjusting member 27 adapted to the guide cylinder 2 is also included. The adjusting member 27 is configured with a threaded hole 81 adapted to the external thread 26, as shown in FIG. Figure 6 and Figure 7 As shown; the return spring 51 is sleeved on the outside of the inner cylinder 31, the lower end of the return spring 51 abuts against the inner shell 1, and the upper end of the return spring 51 abuts against the outer shell 3. For example, the upper end of the return spring 51 may abut against the top cover 34 of the outer shell 3, as shown Figure 6 As shown; the adjusting member 27 is threadedly connected to the guide cylinder 2 so as to limit the inner cylinder 31 between the adjusting member 27 and the inner shell 1, and make the outer shell 3 and the inner shell 1 have a relatively determined positional relationship. On the one hand, a relatively closed inner cavity 36 can be formed between the outer shell 3 and the inner shell 1. On the other hand, an annular gap can be formed between the lower end of the outer shell 3 (the lower end of the outer cylinder 32) and the inner shell 1 (the outer surface of the inner shell 1), and the gap is connected with the inner cavity 36. The gap serves as a smoking port 4 for smoking and forms a circle along the circumferential direction of the moxibustion port 12 to effectively prevent smoke from escaping.

[0052] To facilitate use, during implementation, the outer shell 3 can only move in the vertical direction relative to the inner shell 1 (or the guide cylinder 2), but the outer shell 3 cannot rotate relative to the inner shell 1 (or the guide cylinder 2). Therefore, in one embodiment, a vertical rod can be provided on the outer side of the inner shell 1, and a collar adapted to the vertical rod can be provided inside the outer shell 3. The collar is sleeved on the vertical rod, and the collar and the vertical rod also constitute a moving pair in the vertical direction. Under the restraining action of the two moving pairs, the outer shell 3 can be effectively prevented from rotating relative to the inner shell 1, so that when the adjusting member 27 is rotated, the guide cylinder 2 will not rotate with the adjusting member 27, which is conducive to more convenient use and the adjustment operation can be completed with one hand. Figure 1 and Figure 2As shown, the guide cylinder 2 includes a lower cylinder 21 connected to the inner shell 1 and an upper cylinder 22 connected to the lower cylinder 21. The inner diameter of the lower cylinder 21 is the same as the inner diameter of the upper cylinder 22 and is larger than the outer diameter of the moxa stick 91. The outer contour of the upper cylinder 22 is cylindrical, and the external thread 26 is constructed on the upper cylinder 22. The outer contour of the lower cylinder 21 is square cylinder (such as quadrilateral cylinder, pentagonal cylinder, hexagonal cylinder, etc.); accordingly, as shown in FIG. Figure 6 and Figure 10 As shown, the central channel in the inner cylinder 31 is constructed as a stepped hole, which includes a cylindrical channel section 311 adapted to the upper cylinder 22 and a square column channel section 312 (such as a quadrangular column channel section, a pentagonal column channel section, a hexagonal column channel section, etc.) adapted to the lower cylinder 21. During assembly, the upper cylinder 22 is inserted into the cylindrical channel section 311, and the two only constitute a moving pair, and the lower cylinder 21 is inserted into the square column channel section 312. The two can not only constitute a moving pair, but also effectively prevent relative rotation, so that the outer shell 3 can only move relative to the inner shell 1.

[0053] During implementation, a first step 23 may be formed between the lower cylinder 21 and the upper cylinder 22. Figure 1 As shown, accordingly, a second step 313 can be formed between the cylindrical channel section 311 and the square column channel section 312, as shown in FIG. Figure 6 As shown, the first step 23 corresponds to the second step 313. The cooperation between the first step 23 and the second step 313 can effectively limit the maximum moving distance of the outer shell 3 relative to the inner shell 1, which is more convenient for users to use.

[0054] In this embodiment, the negative pressure connector 54 is fixedly connected to the housing 3 and communicates with the inner cavity 36, thereby being connected to the smoking port 4 via the inner cavity 36. In actual use, the negative pressure connector 54 is mainly used to connect the negative pressure system to generate negative pressure in the inner cavity 36 and the smoking port 4, so as to continuously absorb the smoke around the moxibustion port 12. Figure 1 and Figure 2 As shown, the negative pressure connector 54 can be fixedly arranged on the outer tube 32, and can also be fixedly arranged on the top cover 34. In actual use, not only can the negative pressure be connected through the negative pressure connector 54, but also the moxibustion device can be fixed on the bracket 92 through the negative pressure connector 54. Figure 11 shown.

[0055] In order to prevent the user from being burned by the ash during the moxibustion process, in the embodiment, the moxibustion device further includes a bottom cover 61, such as Figure 7-Figure 9As shown, the bottom cover 61 is constructed with a mesh opening, which is provided with an ash screen 62. The bottom cover 61 is detachably mounted on the lower end of the inner shell 1, and the ash screen 62 covers the moxibustion port 12. Ash falling from the moxa stick 91 is intercepted by the ash screen 62, effectively preventing burns during the moxibustion process. Furthermore, by detachably mounting the bottom cover 61 on the inner shell 1, it is easy to remove and clean the ash. The ash screen 62 can preferably be made of a metal mesh. The bottom cover 61 can be mounted on the inner side of the lower end of the inner shell 1 so that it does not block the smoking port 4, ensuring a good smoking experience.

[0056] During use, after the adjusting member 27 is connected to the guide cylinder 2, the return spring 51 can be in the original length state. At this time, the lower end of the inner shell 1 remains protruding from the lower end of the outer shell 3, as shown in FIG. Figure 12 As shown, the coverage of the negative pressure area is biased toward the outside of the side of the inner shell 1. Figure 12 The area between the dotted lines A and B and the area between the dotted lines C and D is the coverage of the negative pressure area. Figure 12 In the top view, the coverage of the negative pressure area is annular, and the area between the dotted line B and the dotted line C is the smoke area, which corresponds to and covers the part of the patient that needs moxibustion; when the adjusting member 27 is rotated so that the adjusting member 27 gradually approaches the inner shell 1, the return spring 51 is gradually compressed, and the top cover 34 in the outer shell 3 rests on the adjusting member 27 under the action of the return spring 51. During this process, the inner shell 1 gradually rises relative to the outer shell 3. Although the lower end of the inner shell 1 still protrudes from the lower end of the outer shell 3, during this process, the gap between the outer shell 3 and the inner shell 1 gradually decreases (that is, the smoking port 4 gradually decreases), and the coverage of the negative pressure area gradually shifts toward the center of the inner shell 1; when the lower end of the inner shell 1 is flush with the lower end of the outer shell 3, as shown Figure 13 As shown, the gap between the outer shell 3 and the inner shell 1 reaches the minimum value, and the coverage of the negative pressure area is located just below the smoking port 4, as shown in FIG. Figure 13 As shown, Figure 13 The area between the middle dotted line A and the dotted line B and the area between the dotted line C and the dotted line D is the coverage of the negative pressure area, and the area between the dotted line B and the dotted line C is the smoke area. It can be seen that in this process, the coverage component of the smoke area is reduced so as to focus on the local acupuncture points of the moxibustion patient; when the adjusting member 27 is continued to be rotated so that the adjusting member 27 gradually approaches the inner shell 1, the lower end of the inner shell 1 is gradually received in the outer shell 3, as shown in FIG. Figure 14 As shown, during this process, the gap (minimum gap) between the outer shell 3 and the inner shell 1 remains basically unchanged, but due to the obstruction of the lower end of the outer cylinder 32, the coverage of the negative pressure will continue to shift towards the center of the inner shell 1 for a distance, as shown in FIG. Figure 14 As shown, Figure 14The area between the middle dotted line A and the dotted line B, and the area between the dotted line C and the dotted line D are the coverage areas of the negative pressure area, and the area between the dotted line B and the dotted line C is the smoky area. It can be seen that in this process, the coverage area of ​​the smoky area will be further reduced in order to focus on the local acupuncture points of the moxibustion patient. At the same time, the moxa smoke will be more easily inhaled into the surrounding negative pressure area. Figure 14 The inner shell 1 is already at the highest point. Therefore, during production and manufacturing, the relative positions of the first step 23 and the second step 313 can be reasonably set so that when the first step 23 abuts against the second step 313, the coverage of the negative pressure area will basically no longer shift toward the center of the inner shell 1. At this time, due to the cooperation between the first step 23 and the second step 313, the user can no longer continue to rotate the adjustment member 27 downward, and the position of the inner shell 1 in the outer shell 3 reaches the highest point.

[0057] When adjusting member 27 is rotated in the opposite direction, the elastic force of return spring 51 is automatically released, causing outer shell 3 to rise synchronously (or inner shell 1 to fall synchronously), gradually moving the lower end of inner shell 1 downward. In this embodiment, the outer surface of inner shell 1 guides the smoke, effectively changing the position of the negative pressure area by changing the spacing between outer shell 3 and inner shell 1 or their relative positions.

[0058] Since the relative position between the outer shell 3 and the inner shell 1 in the moxibustion device is adjustable, when in use, the user can adjust the relative position between the outer shell 3 and the inner shell 1 according to actual needs, so as to achieve the purpose of effectively adjusting the size of the smoke area, effectively adjusting the size of the smoking port 4 and effectively adjusting the position of the negative pressure area. It can not only realize the moxibustion treatment with visible moxa smoke, but also effectively prevent the moxa smoke from escaping, which is conducive to achieving a better smoking effect and avoiding the occurrence of smoky conditions; it can also ensure that the moxa smoke can reach the patient's skin through visual inspection, so as to achieve a better moxibustion effect.

[0059] In practical application, the moxibustion device is fixed to the bracket 92 (the existing bracket 92 can be used), such as Figure 11 As shown, the moxibustion port 12 is facing the patient's skin 93, and there is a certain distance between the moxibustion port 12 and the skin 93, as shown in FIG. Figure 12 As shown, that is, the lower end of the moxibustion device does not directly contact the patient's skin 93; the moxa stick 91 burns in the combustion chamber 11, and the heat and smoke generated in the combustion chamber 11 are released downward through the moxibustion port 12 and act on the patient's skin 93 to achieve the purpose of treatment. During the moxibustion process, the negative pressure device is connected to the negative pressure connector 54 to generate a continuous negative pressure at the smoking port 4. Since the smoking port 4 is surrounded by a square along the circumference of the moxibustion port 12, a circle of negative pressure can be formed along the circumferential direction of the moxibustion port 12. The moxa smoke released from the moxibustion port 12 will be blocked by the skin 93 after it leaves the moxibustion port 12 and contacts the patient's skin 93, as shown in FIG. Figure 12-14 As shown, under the influence of downward obstruction and upward pressure, the moxa smoke can drift outward, drifting toward the surrounding negative pressure area. Once captured by the negative pressure area, the moxa smoke continuously drifts toward the mouthpiece 4 under the influence of the negative pressure. Thus, during the moxibustion process, the moxa smoke will only be attracted by the surrounding mouthpiece 4 after traveling a certain distance beyond the moxibustion port 12. This creates a smoke-filled area (also referred to as the actual moxibustion treatment area, moxa-smoke contact area, etc.) below the moxibustion port 12 for moxibustion treatment. Within this smoke-filled area, the moxa smoke can smoothly reach the patient's skin and be visible, thereby ensuring a better treatment effect. Furthermore, the moxa smoke released from the moxibustion port 12 is attracted by the surrounding annular mouthpiece 4 and ultimately discharged in a directionally controlled manner through the negative pressure connector 54 and the pipe connecting to the negative pressure connector 54. This prevents the formation of smoke in the room during the moxibustion treatment, facilitating smoke-free moxibustion indoors while ensuring efficacy and low costs, and reducing the risk of air and environmental pollution.

[0060] Example 2:

[0061] The moxibustion device provided in this embodiment further includes an exhaust pipe 52, one end of which is connected to the housing 3, for example, one end of the exhaust pipe 52 is connected to the top cover 34 or the outer tube 32, and the other end of the exhaust pipe 52 is connected to the negative pressure connector 54, such as Figure 4 and Figure 10 As shown, during implementation, the exhaust pipe 52 is also provided with a regulating valve 53 for adjusting the negative pressure, so that the negative pressure of each moxibustion device can be adjusted, which is not only more convenient to use, but also can meet the use needs of more occasions.

[0062] During implementation, the user can adjust the negative pressure of the smoking port 4 through the regulating valve 53 in a timely manner according to factors such as the burning conditions of the moxa stick 91 and the size of the moxa smoke, so as to effectively prevent the moxa smoke from escaping while ensuring the residence time of the moxa smoke in the inner shell 1, so as to ensure that the moxa smoke contacts the skin as much as possible and achieve better treatment effects.

[0063] Example 3:

[0064] In order to further prevent the escape of moxa smoke, in the moxibustion device provided in this embodiment, a first equalizing plate 371 and a second equalizing plate 381 are further provided in the inner cavity 36 of the shell 3, wherein Figure 15 As shown, the first equalizing plate 371 is constructed as an annular structure, the inner ring of the first equalizing plate 371 is connected to the inner cylinder 31, and the outer ring of the first equalizing plate 371 is connected to the outer cylinder 32. The first equalizing plate 371 is preferably arranged horizontally, so that the top cover 34, the first equalizing plate 371, the outer cylinder 32 and the inner cylinder 31 can together form a first equalizing chamber 37; the exhaust pipe 52 is connected to the first equalizing chamber 37, as shown in FIG. Figure 15As shown, the first pressure equalizing plate 371 is constructed with a first vent hole 372 array, and the first vent hole 372 array includes a plurality of first vent holes 372 uniformly distributed along the circumferential direction of the inner ring, as shown in FIG. Figure 15 As shown, each first air vent 372 is respectively connected to the first uniform pressure chamber 37, and the cross-sectional area of ​​the exhaust pipe 52 is larger than the sum of the cross-sectional areas of each first air vent 372, which is conducive to the negative pressure at each first air vent 372 being closer, thereby achieving the purpose of making the negative pressure more evenly distributed along the circumferential direction of the first uniform pressure chamber 37.

[0065] like Figure 15 As shown, the second equalizing plate 381 is constructed as an annular structure, the inner ring of the second equalizing plate 381 is connected to the inner cylinder 31, the outer ring of the second equalizing plate 381 is connected to the outer cylinder 32, the second equalizing plate 381 is preferably arranged horizontally, and the second equalizing plate 381 is arranged below the first equalizing plate 371, as shown in the figure, so that the first equalizing plate 371, the second equalizing plate 381, the outer cylinder 32 and the inner cylinder 31 can together form a second equalizing chamber 38; each first vent 372 is respectively connected to the second equalizing chamber 38, as shown in the figure. Figure 15 As shown, at the same time, the second pressure equalizing plate 381 is constructed with a second vent hole 382 array, and the second vent hole 382 array includes a plurality of second vent holes 382 uniformly distributed along the circumferential direction of the inner ring, as shown in FIG. Figure 15 As shown, each second air vent 382 is respectively connected to the second uniform pressure chamber 38, and the second uniform pressure chamber 38 is connected to the smoking port 4 below through each second air vent 382, ​​and the sum of the cross-sectional areas of each first air vent 372 is greater than the sum of the cross-sectional areas of each second air vent 382, ​​which is conducive to the negative pressure at each second air vent 382 being closer, so as to achieve the purpose of making the negative pressure more evenly distributed along the circumferential direction of the second uniform pressure chamber 38.

[0066] The moxibustion device provided in this embodiment adjusts the distribution of negative pressure in the inner cavity 36 through a two-stage equal pressure cavity, which is conducive to a more uniform distribution of negative pressure along the circumferential direction of the smoking port 4. It can not only achieve a more balanced adsorption force along the circumferential direction of the inner shell 1, thereby achieving a better adsorption effect along the circumferential direction of the moxibustion port 12, avoiding the problem of local negative pressure being too small to cause moxa smoke to escape; it is also conducive to the dispersion of moxa smoke from the center to the surroundings, so that it can contact the skin more evenly and comprehensively, which is conducive to achieving a better moxibustion effect. Figure 15 As shown, the upper end of the return spring 51 can be against the second pressure equalizing plate 381 , and the inner diameter of the second vent hole 382 is smaller than the inner diameter of the first vent hole 372 .

[0067] In a more perfect embodiment, a plurality of partition plates 39 are further provided in the inner cavity 36 of the housing 3, and the upper ends of the partition plates 39 are connected to the second equalizing plate 381, as shown in FIG. Figure 15 and Figure 16As shown, the outer end of the partition plate 39 is connected to the outer cylinder 32, and the partition plate 39 is vertically arranged along the radial direction of the outer cylinder 32. The inner end of the partition plate 39 extends toward the inner cylinder 31, and the lower end of the partition plate 39 extends to the lower end of the outer cylinder 32. The partition plate 39 is configured to fit the outer contour of the inner shell 1, so that when the inner shell 1 is at the highest position in the outer cylinder 32, the lower end of the partition plate 39 can just abut against the outer surface of the inner shell 1, as shown in FIG. Figure 15 As shown, the partitions 39 are evenly distributed along the circumference of the outer cylinder 32, thereby dividing the space below the second pressure-equalizing plate 381 into multiple zones along the circumference. This prevents interference between the zones, thereby facilitating a more evenly distributed negative pressure along the circumference of the inhalation port 4, thereby achieving better smoking and moxibustion effects. In practice, the number of partitions 39 can be determined based on actual needs. Preferably, the number of partitions 39 can be configured to be 4-16, for example, 8 partitions 39.

[0068] Example 4:

[0069] In actual use, it is found that the negative pressure device used to generate negative pressure in the negative pressure system is very easy to be contaminated by moxa smoke, especially the moxa oil and other pollutants carried in the moxa smoke, which can easily enter the motor of the negative pressure device and cause motor pollution or even damage, which will greatly reduce the service life of the motor. To solve this problem, in the moxibustion device provided in this embodiment, the partition plate 39 is a corrugated plate, and the folds of the corrugated plate are distributed in the horizontal direction, such as Figure 17 As shown, the surface of the partition plate 39 presents an uneven structure along the bottom to top direction, so that in the process of conveying the smoke, most of the moxa oil contained in the smoke can be retained on the surface of the partition plate 39, so that most of the moxa oil in the smoke can be effectively removed before the moxa smoke enters the subsequent pipeline 55, effectively reducing the oil content in the smoke, thereby effectively protecting the downstream pipeline 55 and negative pressure equipment, greatly increasing the cleaning cycle of the pipeline 55 and the negative pressure equipment, and facilitating longer stable operation.

[0070] In implementation, the second uniform pressure plate 381 is fixedly installed in the housing 3 and further includes a first bellows 71, a second bellows 72, a third bellows 73 and a fourth bellows 74. The minimum inner diameter of the first bellows 71 is slightly larger than the outer diameter of the inner cylinder 31, so that the first bellows 71 can be sleeved outside the inner cylinder 31, and the maximum outer diameter of the second bellows 72 is slightly smaller than the inner diameter of the outer cylinder 32, so that the second bellows 72 can be sleeved inside the outer cylinder 32. Figure 17As shown, the first bellows 71 and the second bellows 72 have the same height, and the lower ends of the first bellows 71 and the second bellows 72 respectively abut against the second equalizing plate 381, and the first equalizing plate 371 is placed on the first bellows 71 and the second bellows 72; similarly, the minimum inner diameter of the third bellows 73 is slightly larger than the outer diameter of the inner cylinder 31, so that the third bellows 73 can be set outside the inner cylinder 31, and the maximum outer diameter of the fourth bellows 74 is slightly smaller than the inner diameter of the outer cylinder 32, so that the fourth bellows 74 can be set inside the outer cylinder 32, as shown in FIG. Figure 17 As shown, the third bellows 73 and the fourth bellows 74 have the same height, and the lower ends of the third bellows 73 and the fourth bellows 74 respectively abut against the first equalizing plate 371, and the upper ends respectively abut against the top cover 34, as shown in FIG. Figure 17 As shown, by tightening the top cover 34, the first pressure-equalizing plate 371, the first bellows 71, the second bellows 72, the third bellows 73 and the fourth bellows 74 can be fixed. Not only can the bellows be used to effectively intercept the wormwood oil in the smoke and effectively protect the downstream pipeline 55 and the negative pressure equipment, but the first pressure-equalizing plate 371, the first bellows 71, the second bellows 72, the third bellows 73 and the fourth bellows 74 can also be detachably installed, which is very convenient for cleaning or replacing the first pressure-equalizing plate 371 or the bellows. In implementation, the exhaust pipe 52 is preferably connected to the top cover 34, as shown in FIG. Figure 17 shown.

[0071] In order to effectively purify the smoke, a filter device 75 is also included during implementation. The filter device 75 can be arranged in the first equal pressure chamber 37 and / or the second equal pressure chamber 38. Figure 17 As shown, the smoke must pass through the filter element 75 before entering the negative pressure connector 54. The filter element 75 then filters impurities from the smoke, thereby achieving preliminary purification of the smoke within the moxibustion device and facilitating subsequent further processing of the smoke. In practice, the filter element 75 can utilize existing filter materials, such as HEPA filter material, activated carbon, etc. During implementation, it can be removed and replaced through the top cover 34, making it very convenient.

[0072] Example 5:

[0073] The moxibustion device provided in this embodiment further includes a replaceable suction nozzle 8, which is constructed as an annular structure adapted to the outer tube 32, and a threaded hole 81 is constructed on the upper portion of the suction nozzle 8. Figure 18 and Figure 19 As shown, correspondingly, the lower end of the outer cylinder 32 is configured with an external thread 26 adapted to the threaded hole 81 , and the suction nozzle 8 is threadedly connected to the lower end of the outer cylinder 32 .

[0074] like Figure 18 and Figure 19As shown, a guide surface 82 for guiding smoke is constructed below the threaded hole 81 in the nozzle 8. In practice, the guide surface 82 has multiple implementations to form nozzles 8 with different structures, thereby meeting the use requirements of different occasions. For example, in one implementation, the guide surface 82 can be an inwardly curved arc surface, such as Figure 18 As shown, when the nozzle 8 is installed at the lower end of the outer tube 32, the coverage of the negative pressure area can be further offset to the center of the inner shell 1, which can not only further reduce the range of moxibustion, but also more effectively absorb the smoke. For example, in one embodiment, the guide surface 82 can be an outward curved surface, such as Figure 19 As shown, in order to form a trumpet-shaped structure, when the suction nozzle 8 is installed at the lower end of the outer cylinder 32, the coverage of the negative pressure area can be further offset to the outside of the inner shell 1, which can not only further expand the range of moxibustion, but also expand the adsorption range of the smoke, so as to capture the smoke in a larger range.

[0075] In actual use, the user can choose to install or remove the suction nozzle 8 of the corresponding structure according to actual needs, which is not only more flexible to use, but also can adjust the range of moxibustion or the adsorption range of moxa smoke within a larger range, thereby meeting more usage occasions and being more versatile.

[0076] Example 6:

[0077] In order to solve the problem that the user stops moxibustion midway and causes the moxibustion smoke to spread everywhere, the moxibustion device provided in this embodiment has the following features: Figure 20 As shown, it also includes a sealing cover 63, which is configured with an internal thread. Accordingly, the lower end of the outer cylinder 32 is configured with an external thread 26 adapted to the internal thread. The depth of the sealing cover 63 is greater than the maximum distance that the inner shell 1 protrudes from the lower end of the outer shell 3, ensuring that the sealing cover 63 can be sealed and connected to the lower end of the outer cylinder 32 through the cooperation of the internal thread and the external thread 26, and close the combustion chamber 11 and the inner cavity 36, and enable the combustion chamber 11 to communicate with the inner cavity 36, as shown in FIG. Figure 20 As shown; accordingly, Figure 20 As shown, an air inlet hole 28 is further constructed on the side of the guide cylinder 2 . The air inlet hole 28 is connected to the combustion chamber 11 via the guide cylinder 2 , and a sealing plug 29 made of rubber is provided at the air inlet hole 28 .

[0078] In one usage scenario, when the user stops moxibustion midway and there is still some moxa stick 91 left and it is still burning, the user can cover the sealing cover 63 while maintaining the negative pressure to absorb the smoke, and then open the sealing plug 29 to allow outside air to enter the combustion chamber 11 through the air inlet 28. On the one hand, this allows the moxa stick 91 to continue to burn in the combustion chamber 11 to prevent the moxa smoke from overflowing; on the other hand, it prevents the entire inner cavity 36 from being airtight and causing the sealing cover 63 to be unable to be opened. In another usage scenario, when the moxa stick 91 has been burned but a small amount of smoke is still generated, the user can cover the sealing cover 63 and turn off the negative pressure, wait for it to cool down for a period of time, and then open the sealing cover 63 for a period of time, then turn off the negative pressure, and finally open the sealing cover 63 for the cleaning operation. Alternatively, after waiting for a period of cooling, the user can first open the negative pressure and the sealing plug 29 for a period of time, then turn off the negative pressure, and finally open the sealing cover 63 for the cleaning operation.

[0079] Example 7:

[0080] This embodiment provides a moxibustion system, including the above-mentioned moxibustion device, a bracket 92 and a negative pressure system, wherein the negative pressure system includes a negative pressure device and a pipeline for generating negative pressure, such as Figure 11 As shown, the housing 3 of the moxibustion device is fixed to the bracket 92. The bracket 92 has the freedom to adjust the position of the moxibustion device, and the existing bracket 92 can be used; the negative pressure connector 54 of the moxibustion device is connected to the pipeline, as shown in FIG. Figure 11 As shown, the pipeline is connected to the negative pressure device so that negative pressure is formed at the smoking port 4 of the moxibustion device by using the negative pressure system.

[0081] During implementation, the negative pressure equipment can be existing negative pressure equipment such as a negative pressure pump and a negative pressure station. Hoses are preferably used as pipes for ease of layout. During implementation, the pipes of the negative pressure system can be connected to multiple moxibustion devices at the same time to provide negative pressure for multiple moxibustion devices at the same time. In order to effectively remove the oil contained in the smoke, during implementation, a corrugated pipe is preferably used as the pipe. Since the bellows has many corrugations and the inner diameter of the bellows is constantly changing, the oil contained in the smoke can be retained on the inner surface of the bellows during the process of transporting the smoke, thereby effectively removing the oil contained in the smoke, achieving the purpose of effectively reducing the oil content in the smoke, and effectively protecting the negative pressure equipment at the rear end.

[0082] In addition, the moxibustion system also includes a smoke purification device, which can be arranged on the pipeline 55 between the negative pressure connector 54 and the negative pressure device, or can be arranged downstream of the negative pressure device, so as to further purify the moxa smoke by using the smoke purification device, thereby realizing multi-stage purification, which is conducive to achieving a better smoke purification effect. During implementation, the smoke purification device can adopt the smoke purification device commonly used in the prior art, which will not be described in detail here.
