[0013] The diameter of the first flared clamping hole at one end near the combustion chamber is smaller than the diameter at the other end.

[0014] The overflow hole communicates with the smoke exhaust chamber through the gap between each pair of adjacent spring plates.

[0015] According to one embodiment of the present invention, the limiting mechanism further includes a second clamp, and the combustion chamber is provided with a second clamp. The second clamp includes at least two springs, one end of each spring is connected to the inner side wall of the combustion chamber, and the other end of each spring is connected to a clamping block.

[0029] Ignite the hollow moxa stick and place the bottom of the mounting base against the area to be treated. Attach the filter to the moxibustion device structure. The mounting base then passes through the opening in the outer shell and abuts against the outlet of the combustion chamber. The hollow moxa stick passes through the opening in the outer shell and the outlet of the combustion chamber, entering the combustion chamber. Place the outer side of the opening against the area to be treated. Turn on the miniature fan. The miniature fan expels the gas from the exhaust chamber, creating negative pressure. The gas in the hollow chamber flows into the exhaust chamber through the overflow hole. The smoke and heat generated by the combustion of the hollow moxa stick in the combustion chamber...

After being filtered by the filter set in the smoke exhaust chamber, the filtered smoke is discharged to the external space of the outer shell by a micro fan. Since the smoke generated by the hollow moxa stick in the combustion chamber flows into the cavity, a negative pressure is generated in the combustion chamber. Therefore, the gas in the external space of the outer shell is drawn into the combustion chamber through the suction pipe, which can maintain the normal combustion of the hollow moxa stick.

[0030] Because the hollow moxa stick is placed in the combustion chamber and is not directly exposed to the air for combustion, and because the smoke generated when the hollow moxa stick is burning in the combustion chamber is driven by a micro fan, it can pass through the inner hole of the hollow moxa stick, the cavity of the fixing seat, and the overflow hole of the fixing seat in sequence into the smoke exhaust chamber, and then be filtered by the filter set in the smoke exhaust chamber before being discharged, thus reducing the pollution to the surrounding environment.

[0045] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0046] like Figures 1-12 As shown, one embodiment of this utility model provides a filtering device for a moxibustion device structure. The moxibustion device structure includes a fixed base 15 and a hollow moxa stick 17. One end of the hollow moxa stick 17 is inserted into the fixed base 15. The fixed base 15 has a cavity that communicates with the inner hole of the hollow moxa stick 17. An overflow hole 151 is opened on the side wall of the fixed base 15. The filtering device includes a shell. One side of the shell has an opening, and the other side has a miniature fan 3. The shell has a combustion chamber 2 for accommodating the hollow moxa stick 17. One end of the combustion chamber 2 has an outlet 8.

[0047] The mounting bracket 15 passes through the opening in the outer casing and abuts against the outlet 8 of the combustion chamber 2;

[0048] A smoke exhaust chamber 9 is formed between the outer wall of the combustion chamber 2 and the inner wall of the outer shell. The smoke exhaust chamber 9 is connected to the cavity through the overflow hole 151. The smoke exhaust chamber 9 is provided with an air intake pipe 5 that connects the combustion chamber 2 and the external space of the outer shell.

[0049] The exhaust chamber 9 is equipped with a filter 4 for filtering the smoke inside the exhaust chamber 9, and a miniature fan 3 is used to exhaust the filtered smoke to the external space of the outer casing.

[0050] The filter 4 is located at the end away from the outlet 8, and the outlet 8 of the combustion chamber 2 is located at the end near the opening of the outer casing.

[0051] Ignite the hollow moxa stick 17, and place the bottom of the fixing base 15 into the moxibustion area 16 on the human body. Place the filter device onto the moxibustion device structure. At this point, the fixing base 15 passes through the opening of the outer shell and abuts against the outlet 8 of the combustion chamber 2. The hollow moxa stick 17 passes through the opening of the outer shell and the outlet 8 of the combustion chamber 2 in sequence, entering the combustion chamber 2. Place the outer side of the opening into the moxibustion area 16 on the human body. Turn on the miniature fan 3. The miniature fan 3 exhausts the gas from the smoke exhaust chamber 9, creating a negative pressure inside the smoke exhaust chamber 9. The gas in the cavity flows into the smoke exhaust chamber 9 through the overflow hole 151. The smoke produced by the combustion of the hollow moxa stick 17 in the combustion chamber 2... Both air and heat flow into the cavity through its inner hole. The heat generated by the hollow moxa stick 17 can penetrate into the moxibustion site 16 of the human body for moxibustion therapy. Excess heat enters the smoke exhaust chamber 9 through the overflow hole 151 through the cavity. After being filtered by the filter 4 set in the smoke exhaust chamber 9, the filtered smoke is discharged to the external space of the outer shell by the micro fan 3. Since the smoke generated by the hollow moxa stick 17 in the combustion chamber 2 flows into the cavity when it burns, a negative pressure is generated in the combustion chamber 2. Therefore, the gas in the external space of the outer shell is drawn into the combustion chamber 2 through the suction pipe 5, which can maintain the normal combustion of the hollow moxa stick 17.

[0052] Thanks to the filtration device, the moxibustion device structure allows the hollow moxa stick 17 to be placed inside the combustion chamber 2 during use, without being directly exposed to the air for combustion. Furthermore, under the action of the micro fan 3, the smoke generated by the combustion of the hollow moxa stick 17 in the combustion chamber 2 can pass through the inner hole of the hollow moxa stick 17, the cavity of the fixing seat 15, and the overflow hole 151 of the fixing seat 15 into the smoke exhaust chamber 9, and then be filtered by the filter 4 installed in the smoke exhaust chamber 9 before being discharged. Therefore, the pollution to the surrounding environment (the external space of the outer shell) is reduced.

[0053] According to one embodiment of the present invention, the filter device includes a limiting mechanism for limiting the fixing seat 15 within the housing.

[0054] It should be noted that, as Figure 10 As shown, the fixing base 15 in the moxibustion device structure is integrally formed from a base 152 and a fixing post 153. The fixing post 153 has a slot, into which a hollow moxa stick 17 is inserted. A through hole is provided at the bottom of the slot, the diameter of which is smaller than the diameter of the slot. Multiple overflow holes 151 are provided on the side wall of the base 152. The base 152 has an inner cavity, which is connected to the through holes to form the cavity of the fixing base 15. The inner hole of the hollow moxa stick 17 is open vertically, allowing the smoke and heat in the combustion chamber 2 to enter the cavity of the fixing base 15 through the inner hole of the hollow moxa stick 17.

[0055] Preferably, the limiting mechanism includes a first clamp 7, which includes at least two spring pieces 71. One end of each spring piece 71 is fixed to the opening of the outer shell, and the other end of each spring piece 71 is raised toward the outlet 8 of the combustion chamber 2. The multiple spring pieces 71 together form a first flared clamping hole for clamping the base 152. The inner surface of the first flared clamping hole is adapted to the outer surface of the base 152 in the fixed seat 15.

[0056] like Figure 5 As shown, the longitudinal section of the spring 71 is 71a, and the front surface of the spring 71 is 71b, as... Figure 6 As shown, the bottom view of the shrapnel 71 is 71c.

[0057] The diameter of the first flared clamping hole at one end near the combustion chamber 2 is smaller than the diameter at the other end. In the initial state, the diameter of the first flared clamping hole at one end near the combustion chamber 2 is slightly larger than the outer diameter of the hollow moxa stick 17, so that the hollow moxa stick 17 can enter the combustion chamber 2 from the outlet 8 without obstruction after being lit.

[0058] The overflow hole 151 is connected to the smoke exhaust chamber 9 through the gap between each pair of adjacent spring plates 71.

[0059] According to one embodiment of the present invention, the limiting mechanism further includes a second clamp 6. The second clamp 6 is provided in the combustion chamber 2. The second clamp 6 is located at one end of the combustion chamber 2 near the opening of the outer shell. The second clamp 6 includes at least two springs 62. One end of each spring 62 is connected to the inner side wall of the combustion chamber 2, and the other end is connected to a clamping block 61. The multiple clamping blocks 61 cooperate to clamp the fixing seat 15.

[0060] Multiple clamping blocks 61 form a second flared clamping hole that is smaller at the top and larger at the bottom (the top refers to the end closest to the miniature fan 3). In the initial state, the minimum diameter of the second flared clamping hole is slightly larger than the outer diameter of the hollow moxa stick 17. When one end of the fixing seat 15 is inserted into the second flared clamping hole, the spring 62 contracts, so that after one end of the fixing seat 15 is inserted, the multiple clamping blocks 61 can cooperate to clamp the fixing post 153 in the fixing seat 15 under the action of the multiple springs 62.

[0061] According to one embodiment of the present invention, the outer shell includes a housing 1 and a top cover 10, and the top cover 10 and the housing 1 are detachably connected;

[0062] The housing 1 has an opening at the end away from the top cover 10.

[0063] According to one embodiment of the present invention, such as Figure 1 As shown, multiple air intake pipes 5 are provided along the radial direction of the combustion chamber 2, such as... Figure 3As shown, not only are there multiple air intake pipes 5 arranged radially in the combustion chamber 2, but also multiple air intake pipes 5 are arranged axially in the combustion chamber 2.

[0064] Another option is to have multiple air intake pipes 5 only in the axial direction of the combustion chamber.

[0065] The suction pipe 5 has an inlet, which can also be equipped with a detachable air conditioning plug 51. This allows for adjustment of the airflow through the suction pipe 5 during moxibustion by removing or installing the air conditioning plug 51, further enabling flexible temperature control. The number and size of the suction pipes 5 can be determined as needed. The suction pipe 5 connects to the combustion chamber 2, allowing the combustion chamber 2 to be fixed inside the outer casing. The suction pipe 5 draws air from the external space of the casing 1 into the combustion chamber 2 for combustion of the hollow moxa stick 17, while also isolating the air from the smoke.

[0066] Preferred, such as Figure 7 As shown, the outer side wall of the top cover 10 is provided with internal threads, and the housing 1 is composed of a first ring and a second ring. The outer diameter of the first ring is smaller than the outer diameter of the second ring, and the inner diameter of the first ring and the inner diameter of the second ring are the same. The outer side wall of the first ring is provided with external threads, and the top cover 10 is threadedly connected to the housing 1. Alternatively, the top cover 10 can also be inserted into the housing 1.

[0067] Preferably, both the housing 1 and the combustion chamber 2 are made of heat-resistant transparent material, which allows for good observation of the flue gas flow, the fixation of the mounting base 15 to the housing, and whether the filter 4 needs to be replaced or cleaned.

[0068] The top cover 10 has smoke exhaust holes 102 at its end and side wall. The smoke exhaust holes 102 are equipped with detachable smoke regulating plugs 103 for assisting in regulating the smoke flow.

[0069] Adjustment method: When the wind speed of the miniature fan 3 is constant, the smoke flow can be adjusted by using the smoke regulating blockage 103 or the air regulating blockage 51. The more smoke exhaust holes 102 are blocked (or the more inlets of the suction pipe 5 are blocked), the less air is drawn into the suction pipe 5, thus slowing down the burning speed of the hollow moxa stick 17 and reducing the temperature inside the cavity of the fixing base 15. Conversely, the fewer smoke exhaust holes 102 are blocked (or the fewer inlets of the suction pipe 5 are blocked), the greater the amount of filtered smoke discharged, the more air is drawn into the suction pipe 5, increasing the burning speed of the hollow moxa stick 17 and increasing the temperature inside the cavity of the fixing base 15.

[0070] According to one embodiment of the present invention, the filter 4 includes a filter structure and a support mesh 42;

[0071] The support net 42 is detachably connected to the outer casing;

[0072] A pressure ring 12 is connected inside the top cover 10. The pressure ring 12 and the support mesh 42 work together to confine the filter structure inside the housing.

[0073] According to one embodiment of the present invention, the filter structure includes wood-based activated carbon 41 and zeolite molecular sieve 44, which are arranged sequentially along the length of the outer shell. The length of the outer shell is the same as the axial direction of the combustion chamber 2.

[0074] Specifically, wood-based activated carbon 41 and zeolite molecular sieve 44 are sequentially placed into the support mesh 42. Since the support mesh 42 has an outer edge 43, and the inner wall of the top cover 10 has an inner edge 101, the bottom wall of the outer edge 43 is placed against the top wall of the shell 1. After the top cover 10 is connected to the shell 1, the inner edge 101 of the top cover 10 clamps and fixes the outer edge 43 between the inner edge 101 and the top wall of the shell 1 (see...). Figure 7 Meanwhile, the pressure ring 12 connected inside the top cover 10 abuts against the zeolite molecular sieve 44 located on the upper layer, thereby fixing the entire filter structure in place for easy replacement or cleaning. It should be noted that the depth of the support mesh 42 is greater than the thickness of the wood-based activated carbon 41, allowing part of the zeolite molecular sieve 44 to enter the support mesh 42, thus confining the zeolite molecular sieve 44 within the outer shell under the combined action of the support mesh 42 and the pressure ring 12.

[0075] Among them, the bulk density of zeolite molecular sieve 44 is 0.4~0.48 g / cm³. 3 Its microstructure is a regular hexagon, enabling it to adsorb harmful toxins and gases in flue gas. The specific surface area of ​​wood-based activated carbon 41 is 800~1500 m². 2 / g.

[0076] Of course, in this embodiment, two support nets 42 can also be provided, with the two support nets 42 arranged opposite each other, and the zeolite molecular sieve 44 and wood activated carbon 41 placed between the two support nets 42. The distance between the inner bottom walls of the two support nets 42 is equal to the sum of the thickness of the zeolite molecular sieve 44 and the thickness of the wood activated carbon 41. The outer edges 43 of the two support nets 42 are placed between the shell 1 and the top cover 10, and their fixation method is the same as that of a single support net 42, which will not be described in detail here.

[0077] According to one embodiment of the present invention, a sealing ring 81 is provided at the outlet 8 of the combustion chamber 2. The sealing ring 81 is used to seal the gap between the fixing seat 15 and the inner wall of the combustion chamber 2.

[0078] Optionally, the outlet 8 can be designed to fit perfectly with the surface of the base 152, which can also seal the gap between the base 152 and the inner wall of the combustion chamber 2, thereby preventing flue gas from entering the combustion chamber 2.

[0079] According to one embodiment of the present invention, double-sided adhesive 11 is affixed to the outer side of the opening.

[0080] The outer surface of the opening of the outer shell is a ring-shaped plane, which can be bonded to the moxibustion site 16 of the human body by means of double-sided adhesive 11. The double-sided adhesive 11 is ring-shaped, which fixes the entire filter device to the moxibustion site 16 of the human body. The filter device in this embodiment is relatively flexible in use. Preferably, the filter device can be perpendicular to the horizontal direction. Figure 11 Optionally, the filter device is parallel to the horizontal direction. Figure 12 This allows the body of the person receiving moxibustion to be free from the restrictions of fixed position and posture.

[0081] like Figure 1 , Figure 10 , Figure 11 and Figure 12 As shown, the operation process is as follows:

[0082] 1) Align the hollow moxa stick 17 with the first flared clamping hole of the first clamp 7 and push it forward. The hollow moxa stick 17 passes through the first flared clamping hole in sequence. During the process of the hollow moxa stick 17 entering the combustion chamber 2, the base 152 and the fixed column 153 in the fixed seat 15 press the surrounding spring 71 and clamping block 61 respectively. At the same time, the spring 71 and the clamping block 61 are obstructed and generate a reverse squeezing force on the base 152 and the fixed column 153.

[0083] 2) After the fixed base 15 is fully inserted into the first flared clamping hole, the fixed base 15 is fixed to the outer shell by the elastic force generated by the compression of the spring piece 71, the clamping block 61 and the spring 62. At the same time, it is necessary to ensure that the overflow hole 151 is aligned with the gap between the adjacent spring pieces 71.

[0084] 3) Stick the double-sided tape 11 on the outer side of the opening and the double-sided tape 11 on the base 152 around the moxibustion site 16 on the human body (the double-sided tape 11 on the base 152 does not need to be stuck).

[0085] 4) Start the miniature fan 3;

[0086] 5) After the hollow moxa stick 17 has burned out, separate the outer shell from the fixing base 15 and remove it from the human body.

[0087] In this embodiment, the first clamp 7 and the second clamp 6 cooperate with the base 152 and the fixing post 153 in the fixing seat 15, respectively, to achieve an effective connection between the moxibustion device structure and the outer shell. Air is introduced into the combustion chamber 2 through the suction pipe 5. Figure 11The direction indicated by the first arrow 13 in the diagram is the direction of airflow, ensuring the normal combustion of the hollow moxa stick 17. Through the gap between adjacent spring pieces 71 in the first clamp 7, the cavity of the fixing seat 15 is connected to the smoke exhaust chamber 9 via the overflow hole 151, allowing the smoke generated by the combustion of the hollow moxa stick 17 to overflow from the overflow hole 151 through the inner hole of the hollow moxa stick 17 and the cavity of the fixing seat 15, before being drawn into the smoke exhaust chamber 9. Figure 11 The direction indicated by the second arrow 14 is the direction of the flue gas flow. Finally, after being filtered by the filter 4, the flue gas is discharged through the miniature fan 3 on the top cover 10 and multiple exhaust holes 102.
