Description

Technical Field

[0001] The utility model relates to the technical field of oxygen concentrators, in particular to a filtering device for an oxygen concentrator. Background Art

[0002] Oxygen generator is a type of machine that produces oxygen. Its principle is to use air separation technology. First, the air is compressed at a high density, and then the different condensation points of the components in the air are used to separate the gas and liquid at a certain temperature, and then further distilled. The oxygen generator needs to use filtering equipment in the oxygen production process.

[0003] Usually, most air filtration equipment is divided into multi-stage filtration during use to ensure the cleanliness of the air and facilitate later use. For example, the HEPA filter plate in the air filtration equipment contains a HEPA filter element, which can effectively remove ultrafine particles, bacteria and viruses. For example, the antibacterial cloth filter element can remove allergens, dust mites, etc. When the filter plate is used for a long time, the surface is easy to absorb impurity particles, such as dust particles, hair, etc. If it is not cleaned in time, it will affect the use of the filtration equipment, thereby causing trouble to the staff. For this reason, we proposed an oxygen generator filtration equipment to solve the above problems. Utility Model Content

[0026] Through the above technical scheme, the formaldehyde, benzene, xylene, TVOC, allergens, dust mites and other pollutants contained in the air can be effectively filtered and removed through the multi-stage filter plate 7, thereby achieving the effect of one-time filtration. Through the HEPA filter plate 20, it is convenient to filter and remove ultrafine particles, bacteria, viruses and the like in the air, thereby ensuring the quality of the air. By adding the electric push rod 17, it is convenient to push the sliding plate 18 to move, so that the sliding plate 18 drives the moving plate 10 to move, and the cleaning brush 12 is driven by the moving plate 10 to move, which can effectively clean the impurity particles adsorbed on the surface of the HEPA filter plate 20 and the multi-stage filter plate 7, and avoid the impurity particles from clogging the filter holes, thereby improving the filtration efficiency of the multi-stage filter plate 7 and the HEPA filter plate 20.

[0027] Specifically, the back of the filter box 3 is fixedly connected to the box body 11, and a dust collector 15 is fixedly installed on the right side of the bottom of the inner cavity of the box body 11. A dust outlet pipe 16 is fixedly connected to the top of the dust collector 15, and a conveying pipe 14 is fixedly connected to the left side of the dust collector 15. A dust suction pipe 9 is fixedly connected to the surface of the conveying pipe 14, and the surface of the dust suction pipe 9 penetrates into the inner cavity of the filter box 3 and is fixedly connected to a dust suction head 6. The bottoms of both sides of the dust collector 15 are fixedly connected to mounting blocks, and the surfaces of the mounting blocks are provided with mounting bolts. The left side of the bottom of the inner cavity of the box body 11 is fittedly connected with a dust collecting box 13, and an air outlet is provided on one side of the dust collecting box 13, and a filter is provided on the surface of the air outlet. Slide rails 19 are fixedly connected to both sides of the inner cavity of the shell 4, and both sides of the sliding plate 18 are slidably connected in the inner cavity of the slide rails 19. The inner cavity of the PA filter plate 20 includes an activated carbon filter element and an antibacterial cloth filter element. When the cleaning brush 12 is cleaning the surface of the multi-stage filter plate 7 and the HEPA filter plate 20, the user starts the vacuum cleaner 15 through an external controller, and the vacuum cleaner 15 drives the conveying pipe 14 to absorb the cleaned dust and impurity particles. Due to the influence of suction, the dust and impurity particles are absorbed by the dust suction pipe 9 and the dust suction head 6, and are discharged to the inner cavity of the dust box 13 through the cooperation of the dust outlet pipe 16 for collection. The gas generated by the vacuum cleaner 15 is discharged through the air outlet of the inner cavity of the dust box 13.

[0028] The working principle of the utility model is as follows: first, when the fixing plate 1 is in operation, suction is generated, and the suction is transmitted to the inner cavity of the filter box 3 through the suction pipe 8. Due to the influence of the suction, the air enters the inner cavity of the filter box 3 through the through hole on the right side of the filter box 3, and is filtered through the multi-stage filter plate 7. The multi-stage filter plate 7 can effectively filter and remove formaldehyde, benzene, xylene, TVOC, and allergens, dust mites and other pollutants contained in the air, thereby achieving a one-time filtering effect. After the multi-stage filter plate 7 has filtered, it is transmitted to the HEPA filter plate 20 for filtering. Through the HEPA filter plate 20, it is convenient to filter and remove ultrafine particles, bacteria, viruses and the like in the air, thereby ensuring the quality of the air. After being filtered by the HEPA filter plate 20 and the multi-stage filter plate 7, the air is transported to the inner cavity of the oxygen generator body 2 through the suction pipe 8 for operation by the staff. When the HEPA filter plate 20 and the multi-stage filter plate 7 are used for a long time During use, the surface is easy to absorb foreign particles. The user regularly starts the electric push rod 17 and the vacuum cleaner 15 at the same time through the external controller, and pushes the sliding plate 18 to move through the electric push rod 17. The movement of the sliding plate 18 drives the moving plate 10 to move, and the movement of the moving plate 10 drives the cleaning brush 12 to move. The movement of the cleaning brush 12 removes the foreign particles adsorbed on the surfaces of the HEPA filter plate 20 and the multi-stage filter plate 7. At the same time, the vacuum cleaner 15 drives the conveying pipe 14 to absorb the cleaned dust and foreign particles. Due to the influence of suction, the dust and foreign particles are absorbed by the dust suction pipe 9 and the dust suction head 6, and are discharged into the inner cavity of the dust collecting box 13 through the cooperation of the dust outlet pipe 16 for collection. The gas generated by the vacuum cleaner 15 is conveniently discharged through the air outlet of the inner cavity of the dust collecting box 13. The dust and foreign particles are blocked in the inner cavity of the dust collecting box 13 through the filter screen on the surface of the air outlet. Then, the user regularly cleans the dust and foreign particles in the inner cavity of the dust collecting box 13.
