Air purification filter element for purifying moxa smoke

Abstract

The utility model relates to an air purification filter element for purifying moxa smoke, which is integrally plate-shaped or barrel-shaped in structure and comprises an oil absorption layer, a water absorption layer, a total volatile organic compound (TVOC) filter layer and a composite filter layer which are sequentially connected from an air inlet side to an air outlet side. Moxa smoke sequentially passes through the water absorption layer, the TVOC filtering layer and the composite filtering layer from one side of the oil absorption layer, and oil gas, water vapor, TVOC, PM2.5 particles and the like generated after moxa stick combustion are filtered. The utility model has the advantages that the structural design is reasonable, the effect of step-by-step filtration is realized, and the negative influence of oil and water on other gases and particulate matters can be reduced by preferentially adsorbing oil fume and water vapor through the filter elements of the first two layers. And the adsorption service life of the TVOC and PM2.5 filter element can be prolonged while high-efficiency filtration is ensured. And the third layer and the fourth layer can effectively prolong the service life of the filter element through stepped filtration of gas TVOC (Total Volatile Organic Compounds). Moxa smoke can be effectively filtered.

Description

Technical Field

[0001] This utility model relates to an air purification filter element, specifically an air purification filter element for purifying moxa smoke. Background Technology

[0002] Moxibustion, a traditional Chinese medicine therapy, is used for both treatment and health maintenance, and has effects such as promoting metabolism, clearing meridians, and activating blood and qi. With the continuous development of the moxibustion industry, the emergence of moxibustion robots has made moxibustion for health maintenance faster and more convenient. However, the smoke produced by burning moxa sticks causes environmental pollution. Moxibustion robots are generally equipped with air purification filters to address the air pollution caused by moxa smoke.

[0003] The composition of moxa smoke is very complex. In current technology, the air purification filter of moxibustion robot generally only uses conventional non-woven fabric filter or composite activated carbon filter, which cannot effectively remove pollutants in moxa smoke for a long time. Utility Model Content

[0004] This utility model proposes an air purification filter for purifying moxa smoke, which aims to overcome the above-mentioned shortcomings of the existing technology and improve the purification effect of moxa smoke.

[0005] The technical solution of this utility model is an air purification filter element for purifying moxa smoke. Its structure is integrally plate-shaped or barrel-shaped, including an oil-absorbing layer, a water-absorbing layer, a TVOC filter layer, and a composite filter layer connected sequentially from the air inlet side to the air outlet side. The composite filter layer is a W or M-shaped pleated filter material, composed of a double-layer particulate filter layer filled with activated carbon in the middle. The particulate filter layer is made of non-woven fabric or meltblown fabric, with a particulate filtration grade of H10, H11, H12, or H13. Moxa smoke passes sequentially from the oil-absorbing layer to the water-absorbing layer, TVOC filter layer, and composite filter layer, filtering oil vapor, water vapor, TVOC, PM2.5 particles, etc., produced after the moxa sticks burn.

[0006] Preferably, the activated carbon filled in the middle of the composite filter layer is wood charcoal or coconut shell charcoal, and is in the form of powder or granules.

[0007] Preferably, the oil-absorbing layer is a W or M type pleated filter material, made of PP, PET or PBT.

[0008] Preferably, the absorbent layer is a plastic mesh skeleton with internally loaded absorbent particles.

[0009] Preferably, the water-absorbing particles are molecular sieves or water-absorbing resins.

[0010] Preferably, the TVOC filter layer comprises columnar carbon particles.

[0011] The advantages of this invention are: Its reasonable structural design achieves a step-by-step filtration effect. The first two filter layers preferentially adsorb oil fumes and water vapor, reducing the negative impact of oil and water on other gases and particulate matter. This extends the adsorption life of the TVOC and PM2.5 filter elements while ensuring high-efficiency filtration. The third and fourth layers, through their tiered filtration of gas TVOC, effectively extend the filter element's lifespan. It also effectively filters moxa smoke. Attached Figure Description

[0012] Figure 1 This is a schematic diagram of the structure of the air purification filter element for purifying moxa smoke according to this utility model.

[0013] In the diagram, 1 is the oil-absorbing layer, 2 is the water-absorbing layer, 3 is the TVOC filter layer, and 4 is the composite filter layer. Detailed Implementation

[0014] The present invention will be further described in detail below with reference to embodiments and specific implementation methods.

[0015] like Figure 1 As shown, an air purification filter for purifying smoke has a structure that is integrally plate-shaped or barrel-shaped, including an oil-absorbing layer 1, a water-absorbing layer 2, a TVOC filter layer 3, and a composite filter layer 4 connected sequentially from the air inlet side to the air outlet side.

[0016] The oil-absorbing layer 1 is specifically a W or M type pleated filter material, which can be made of PP, PET or PBT, with a pleat spacing of 6-10mm and an overall height of 25-35mm.

[0017] The absorbent layer 2 specifically includes a plastic mesh skeleton (a plastic skeleton with a number of regular mesh holes), which is loaded with absorbent particles. The absorbent particles can be molecular sieves, absorbent resins, etc. The mesh diameter is 10-15mm, and the mesh holes are circular, hexagonal, or octagonal. The overall height is 30-60mm.

[0018] TVOC filter layer 3 specifically includes columnar carbon particles with an overall height of 50-100mm.

[0019] The composite filter layer 4 is specifically a W or M type pleated filter material, consisting of a double-layer particulate filter layer filled with activated carbon in the middle. It is used to filter TVOC and PM2.5 particulate matter. The particulate filter layer can be non-woven fabric, meltblown, etc. The particulate filtration level is H10, H11, H12 or H13. The activated carbon can be wood charcoal or coconut shell charcoal. The shape can be powder or granules. The overall height is 30-60mm.

[0020] Based on the above structure, the smoke from the moxa stick passes sequentially through the oil-absorbing layer 1, the water-absorbing layer 2, the TVOC filter layer 3, and the composite filter layer 4, effectively filtering the oil vapor, water vapor, TVOC, PM2.5 particles, etc. produced after the moxa stick is burned.

[0021] All of the components described above are existing technologies, and those skilled in the art can use any model and existing design that can achieve their corresponding functions.

[0022] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present utility model, and these all fall within the protection scope of the present utility model.
