Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of moxibustion device manufacturing, and in particular to a smoke filter layer used on a moxibustion device and a manufacturing method thereof. Background Art
[0002] There is an existing Chinese utility model patent with patent number CN202022515972.8 and the name of "A Moxibustion Device", which discloses a moxibustion device, including a moxibustion tube composed of an inner tube and an outer tube and a moxa stick arranged in the moxibustion tube, air holes are respectively opened on the tube walls of the inner tube and the outer tube, and a moxibustion tube cover is installed along the upper end of the inner tube, the vertical wall of the moxibustion tube cover is tightly fitted with the inner wall of the inner tube, and the moxibustion tube cover can slide axially relative to the inner tube; a moxa stick mounting seat is inserted in the center hole of the moxibustion tube cover, and the moxa stick is embedded in the lower end of the moxa stick mounting seat; a smoke filter material layer is sandwiched between the inner tube and the outer tube, and the moxibustion device can quickly and easily adjust the distance between the moxa stick and the skin, making it easy to use. However, there is still room for improvement in the smoke filter layer structure of the moxibustion device, so the smoke filter layer structure of the moxibustion device needs further improvement. Summary of the Invention
[0003] The first technical problem to be solved by the present invention is to provide a smoke filter layer for a moxibustion device with good smoke filtering effect, heat resistance and fire resistance, and long service life in response to the above-mentioned existing technical status.
[0004] The technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows: the smoke filter layer used on the moxibustion device includes a sheet that can be rolled into a tube and attached to the inner wall of the moxa tube, and is characterized in that: the sheet includes a heat-resistant first layer, a second layer that can pass through smoke and dust, a third layer that can adsorb smoke and dust, and a fourth layer that is breathable and filters smoke. The third layer is sandwiched between the second layer and the fourth layer, the first layer is attached to the surface of the second layer, and the surface of the first layer is distributed with breathable through holes.
[0005] As an improvement, the first layer can preferably be a reflective sheet made of aluminum foil, with the bottom surface of the first layer bonded to the surface of the second layer using a hydrosol. Aluminum foil is heat-resistant and fire-resistant, helping to extend the life of the moxibustion tube. Aluminum foil's light-reflective properties help to concentrate heat radiation and enhance the moxibustion effect.
[0006] As a further improvement, one end of the first layer may be preferably provided with a smooth tail section without a through hole. When the sheet is rolled into a cylindrical shape, the smooth tail section is adhered to the surface of the fourth layer by glue. This facilitates the production of the cylindrical structure and reduces the difficulty of production and installation.
[0007] As an improvement, the third layer can be preferably a filter layer composed of activated carbon distributed between the fourth layer and the second layer, which has a good smoke and dust adsorption effect, is non-toxic, and is green and environmentally friendly.
[0008] As a further improvement, the second layer may preferably be a non-woven fabric layer. The activated carbon adhesion effect meets the requirements and helps to save costs.
[0009] As a further improvement, the fourth layer can be preferably a filter layer made of Hepa fiber, which has a good filtering effect.
[0010] The second technical problem to be solved by the present invention is to provide a method for manufacturing a smoke filter layer for a moxibustion device that has good smoke filtering effect, is heat-resistant and fire-proof, and has a long service life, in response to the above-mentioned existing technical status.
[0011] The technical solution adopted by the present invention to solve the above technical problems is: the method for manufacturing the smoke filter layer on the moxibustion device is characterized by comprising the following steps:
[0012] 1. Spread the prepared non-woven fabric onto the spraying platform;
[0013] 2. Evenly spray a layer of glue on the upper surface of the non-woven fabric, and evenly sprinkle the prepared activated carbon powder on the wet surface of the non-woven fabric after spraying the glue;
[0014] 3. After the glue solidifies, cut the non-woven fabric coated with activated carbon and place the non-woven fabric coated with activated carbon in a molding device;
[0015] 4. Spraying HEPA fiber into the mold cavity of the molding device so that the HEPA fiber adheres to the activated carbon layer;
[0016] 5. Close the molding device to make the HEPA fiber fit tightly on the activated carbon layer;
[0017] 6. Take out the pressed three-layer structure and apply hydrosol on the surface of the three-layer structure corresponding to the non-woven fabric;
[0018] 7. Adhere the aluminum foil with through holes to the non-woven fabric layer through a hydrosol;
[0019] 8. After the hydrosol solidifies, the sheet is cut into a predetermined shape, thus completing the production of the smoke filter layer.
[0020] As an improvement, in step 2, the activated carbon can be preferably selected from coal dust, wood dust, and coconut shell dust, which has a wide range of materials and strong adaptability.
[0021] As an improvement, in step 2, the activated carbon can be evenly sprinkled on the glue surface of the non-woven fabric by a powder spreading machine. A more even distribution of the activated carbon can help improve the filtering effect.
[0022] As an improvement, the thickness of the smoke filter layer can be preferably 2.5-3.5 mm, the thickness of the activated carbon layer can be preferably 1-1.5 mm, the thickness of the hepa fiber layer can be preferably 0.8-1 mm, and the thickness of the aluminum foil and non-woven fabric layers can be preferably 0.7-1 mm. This thinness takes up little space and has little impact on the original moxibustion tube structure.
[0023] Compared with the prior art, the advantages of the present invention are: the structure of the smoke filter layer is changed, and a four-layer structure is adopted, wherein the innermost layer is made of heat-resistant material, which is heat-resistant and fire-proof, safer to use, and also helps to extend the service life of the moxibustion tube; the third layer can absorb smoke and dust, thereby filtering the smoke and dust produced by the burning of the moxibustion column, and realizing smokeless moxibustion; the third layer is sandwiched between the second and fourth layers, and the structure is more stable. At the same time, the fourth layer also has a smoke filtering effect, further improving the smoke filtering performance of the smoke filter layer. This production method uses non-woven fabric directly as the attachment substrate of activated carbon, which reduces the production steps and improves production efficiency. After attaching the activated carbon, the Hepa fiber is sprayed on the surface of the sheet body, and the Hepa fiber is directly attached to the sheet body by molding and high temperature. The overall attachment is firm, and the use of glue is omitted. It is more environmentally friendly and the overall structure is more compact, which helps to reduce the thickness of the smoke filter layer and reduce the occupied space in the moxibustion tube.
