Description

Technical Field

[0001] This utility model relates to the field of moxibustion equipment technology, and in particular to a low-smoke moxibustion tool that can be used with an open flame. Background Technology

[0002] Moxibustion uses burning moxa wool or moxa sticks to generate a warming effect, which stimulates acupoints on the body to achieve the purpose of unblocking meridians, regulating qi and blood, and preventing and treating diseases.

[0003] Traditional moxibustion boxes mainly consist of a box body and a needle inside the box for fixing the moxa stick, or the box body can be filled with moxa wool. To prevent burns, a heat insulation sleeve can also be installed on the outside of the box. When using it, light the moxa wool or moxa stick, and then align the acupoint hole at the bottom of the box with the acupoint on the human body for moxibustion.

[0004] However, traditional moxibustion boxes contain an open flame during moxibustion and produce a lot of smoke, which not only affects the indoor environment but may also irritate the human respiratory system and pose a fire hazard. In addition, although the heat insulation sleeves provided with traditional moxibustion boxes can reduce the probability of burns, improper operation can still easily lead to skin burns, limiting their widespread use in modern homes and hospitals.

[0035] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings. It should be understood that the described embodiments are merely some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0036] like Figure 1-17 As shown in some illustrative embodiments, a low-smoke moxibustion device with an open flame is provided, including a smoke control device 100, a smoke filter device 200, and a main moxibustion box 300 arranged sequentially from top to bottom. It has the advantages of low smoke, environmental protection, safety, reliability, and easy operation.

[0037] The smoke control device 100 is located at the top of the moxibustion device and has a built-in silent fan to generate negative pressure and guide the flow of smoke. When the fan 150 is started, it draws air from inside the moxibustion device, thereby generating negative pressure on the side of the smoke filter device 200, so that the smoke generated by combustion in the main moxibustion box 300 is drawn into the smoke filter device 200 for filtration.

[0038] The smoke filter 200 is located below the smoke control device 100 and above the main moxibustion box 300. It is used to filter the smoke emitted from the main moxibustion box 300, effectively reducing the concentration of harmful substances in the smoke, reducing the smell of smoke, and improving indoor air quality.

[0039] The moxa stick burning with an open flame is placed inside the main moxibustion box 300, which provides space for the burning of the moxa stick. The main moxibustion box 300 is made of aluminum alloy, which is lightweight and has good thermal conductivity. At the same time, a heat-resistant layer is laminated on the inner surface to prevent high temperature from damaging the aluminum alloy.

[0040] This application, through the cooperation of the smoke control device 100 and the smoke filter device 200, significantly reduces the smoke emission during the moxibustion process, reduces the impact on the indoor environment, and retains the therapeutic effect of traditional moxibustion while solving the problems of smoke and safety hazards in the traditional moxibustion process.

[0041] like Figure 5-7As shown, the flue gas filtration device 200 includes: a housing 210 and a filter element disposed within the housing 210. The filter element includes a water-grade non-woven cotton cloth layer 220, a polyester cotton cloth layer 230, and an activated carbon layer 240. The water-grade non-woven cotton cloth layer 220, the polyester cotton cloth layer 230, and the activated carbon layer 240 are stacked together in a certain order to form a multi-layer filter element. The edges of each layer can be designed to overlap or fixed with a special adhesive, such as... Figure 17 The image shows one type of stacking method. The outer shell 210 protects the internal filter element and provides fixation and support; the water-grade non-woven cotton fabric 220 has good filtration performance and breathability, and is mainly used for preliminary filtration of larger smoke particles and impurities; the polyester material has high heat resistance and chemical stability, and the polyester cotton fabric layer 230 is used for further filtration of fine smoke particles; the activated carbon has extremely strong adsorption capacity, so the activated carbon layer 240 can effectively remove harmful gases and fine particles from the flue gas.

[0042] like Figure 3 and 4 As shown, the smoke exhaust control device 100 includes: a USB interface 110, a PCB board 120, a battery 130, a mounting plate 140, a fan 150, a cover plate 160, and a housing 170.

[0043] The PCB board 120, battery 130, mounting plate 140, and fan 150 are arranged sequentially from top to bottom on the cover base plate 160, allowing each part to be pre-assembled into a whole for easy subsequent installation into the housing 170. The cover base plate 160 is located at the lower opening of the housing 170, thus forming an inner cavity structure together with the housing 170, thereby enclosing the PCB board 120, battery 130, mounting plate 140, and fan 150 within the housing 170. This design has the advantages of compact structure and easy assembly.

[0044] USB interface 110 provides a charging and data transfer interface, facilitating user charging of battery 130 or communication with external devices. It is located on the top of housing 170 for easy user access. PCB board 120 controls the operation of the entire smoke exhaust system, including starting and stopping fan 150, managing battery 130, and signal processing. PCB board 120 integrates necessary electronic components and circuits and is the core control unit of smoke exhaust control device 100.

[0045] Battery 130 provides power to fan 150 and PCB board 120, and can be a lithium-ion battery or other types of rechargeable battery. Mounting plate 140 is used to fix fan 150 and battery 130; specifically, mounting holes or clips can be designed on mounting plate 140 to mate with corresponding components of fan 150 and battery 130. When fan 150 is working, it generates negative pressure, drawing air from inside the moxibustion device and guiding the smoke flow towards smoke filter device 200.

[0046] A ventilation slot 171 is provided on the housing 170. The ventilation slot 171 provides an outlet for the air drawn by the fan 150, ensuring that the flue gas can be smoothly discharged to the outside of the device. At the same time, the ventilation slot 171 helps with heat dissipation, preventing the fan 150 and battery 130 from overheating during long-term operation. The ventilation slot 171 is located on the side and top of the housing 170 to facilitate the rapid discharge of flue gas.

[0047] like Figure 4 , 5 As shown in Figure 6, an L-shaped locking groove 211 is provided at the top outer edge of the outer casing 210, and a locking block 172 is provided on the inner side of the bottom end of the casing 170. When assembling the smoke exhaust control device 100 and the smoke filter device 200, after aligning the locking block 172 with the L-shaped locking groove 211, the bottom of the casing 170 is placed on the top of the outer casing 210. Then, the smoke exhaust control device 100 is rotated, so that the locking block 172 moves laterally within the L-shaped locking groove 211 to the innermost side of the groove, thereby achieving axial positioning of the casing 170 by the L-shaped locking groove 211, thus completing a quick and stable connection between the smoke exhaust control device 100 and the smoke filter device 200.

[0048] An interface 161 is provided on the bottom plate 160 at the position corresponding to the air inlet of the fan 150. The exhaust port 212 of the flue gas filter is embedded in the interface 161, so as to connect the air inlet of the fan 150 and the exhaust port 212 of the flue gas filter. This ensures that the flue gas filtered by the flue gas filter 200 can smoothly enter the smoke exhaust control device 100, reducing airflow loss and improving smoke exhaust efficiency.

[0049] like Figure 8-16 As shown, the main moxibustion box 300 includes: box body 310, box lid 320, heat insulation cover 330, primary smoke guide plate 340 and secondary smoke guide plate 350.

[0050] The lid 320 is located at the upper opening of the box body 310 and surrounds the box body 310 to form the moxibustion combustion chamber. The heat-insulating cover 330 is located on the upper surface of the lid 320. The box body 310 can be cylindrical, cuboid, elliptical, etc., for example... Figure 8 As shown, the box body 310 is composed of an outer shell 311 and an inner shell 312. A heat insulation cavity 313 is formed between the inner shell 312 and the outer shell 311 to reduce heat conduction from the side of the box body to the outside, thus providing heat insulation. Several holes 314 are provided inside the inner shell 312 for inserting moxa sticks for open flame burning.

[0051] like Figure 9-10 As shown, the cover 320 includes: an annular surrounding plate 321, a top sealing plate 322, and a mounting port 323. The mounting port 323 is disposed on the top sealing plate 322 and is used to connect with the flue gas filter device 200.

[0052] The annular enclosure 321 is connected to the top of the box body 310, i.e., located at the upper edge of the box body 310, forming an annular enclosure. The top cover 322 is located at the top of the annular enclosure 321, thereby forming a lower-opening cavity structure for guiding and dispersing flue gas. The primary flue gas guide plate 340 and the secondary flue gas guide plate 350 are located within this cavity structure. Figure 12 As shown, several sets of small-diameter flue gas through holes 351 are formed on the secondary flue gas guide plate 350 to further refine and adjust the flow direction of the flue gas, such as... Figure 11 As shown, the primary flue gas guide plate 340 has large-diameter flue gas passage holes 341 at the positions corresponding to the small-diameter circular holes 351 of each group, which are used to initially guide the flow of flue gas.

[0053] like Figure 13 As shown, the top cover plate 322 is spaced a certain distance from the secondary flue gas guide plate 350, and the primary flue gas guide plate 340 is spaced a certain distance from the secondary flue gas guide plate 350. This spacing design creates a buffer zone, allowing the flue gas to have a brief pause and buffer before entering the secondary flue gas guide plate 350 and the mounting port 323 of the top cover plate 322, which helps to ensure uniform distribution of the flue gas. Furthermore, the size of the spacing can affect the flue gas velocity and flow rate; by adjusting this spacing, the flue gas guiding effect can be optimized.

[0054] The design of the lid 320 helps to distribute and cool the smoke evenly. It can effectively guide and regulate the smoke generated during moxibustion. The smoke is controlled and distributed by the primary smoke guide plate 340 and the secondary smoke guide plate 350, which prolongs the residence time of the smoke in the smoke filter device 200, improves the filtration efficiency, and is also beneficial to the long-term use of the fan 150.

[0055] like Figure 7 and 13 As shown, the mounting port 323 is used to connect the smoke filter device 200 and the main moxibustion box 300. After connection, the air inlet 214 of the smoke filter device is connected to the internal space of the main moxibustion box 300. A notch 324 is provided on the mounting port 323 to form a lever 325. The lever 325 is formed by the notch 324 on the mounting port 323 and can swing around one end of the notch to produce deformation. The function of the lever 325 is to provide an elastic connection during assembly, so that the two devices can be smoothly connected. A limiting block 326 is provided at the end of the lever 325, and a limiting groove 213 corresponding to the limiting block 326 is provided on the inner wall of the outer shell 210.

[0056] During assembly, align the lever 325 with the limiting groove 213, then slip the bottom of the smoke filter device 200 onto the top of the main moxibustion box 300 until the limiting block 326 is embedded in the limiting groove 213. The connection between the two devices can be completed through this simple fitting operation. The design of the limiting block 326 and the limiting groove 213 ensures the stability of the connection. When it is necessary to replace or clean the smoke filter device 200, the two devices can be easily separated by reversing the operation.

[0057] In this embodiment, the connection between the smoke exhaust control device 100 and the smoke filter device 200 is achieved through the L-shaped locking groove 211 and the locking block 172, and the connection between the smoke filter device 200 and the main moxibustion box 300 is achieved through the mounting port 323 and the limiting groove 213. This allows the smoke filter device 200 to be quickly assembled and disassembled, which facilitates the maintenance / replacement of the smoke filter device 200. The structural design also has the advantages of stable connection and not easy to loosen.

[0058] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
