Description

Technical Field

[0001] The utility model belongs to the field of air filters, and in particular relates to a waterproof and dustproof air filter. Background Art

[0002] The oxygen concentrator is a commonly used medical and health equipment. It mainly uses an air compressor to suck the outside air into the inside of the oxygen concentrator, then extracts the air to the adsorption tower, uses the adsorption tower to separate oxygen and nitrogen, and finally collects the oxygen for the user to inhale. The oxygen concentrator includes an air filter, and the outside air is filtered by the air filter before entering the inside of the oxygen concentrator. In order to prevent rainwater from invading the interior of the oxygen concentrator and reduce the damage of the outside air to the compressor, a corresponding waterproof and dustproof structure needs to be set.

[0003] The patent application with announcement number CN219186245U discloses a waterproof and dustproof air filter, including: a waterproof and dustproof net, a grid frame, a bracket and a sealing ring. The sealing ring and the grid frame are respectively installed at the air inlet of the oxygen concentrator, the sealing ring is arranged on the grid frame, the sealing ring is used to seal the grid frame, the bracket, the waterproof and dustproof net and the grid frame are arranged in a superimposed manner, the waterproof and dustproof net covers the air inlet, and the waterproof and dustproof net is used for waterproofing and dustproofing; the grid frame has a plurality of columns, and each column synchronously penetrates the waterproof and dustproof net and extends to embed the bracket. In this way, it effectively isolates rainwater from intrusion, and effectively isolates dust larger than 10um from being inhaled into the interior of the oxygen concentrator, which plays a protective role for the oxygen concentrator; at the same time, the waterproof and dustproof net, the grid frame and the bracket are assembled and disassembled through the columns, can be repeatedly cleaned and reused, are more environmentally friendly and durable, and the waterproof and dustproof net, the grid frame and the bracket are embedded and matched, the structure is more compact, the thickness is thin, which is conducive to reducing the overall volume of the oxygen concentrator and saving space.

[0004] However, the above technology has the following disadvantages when used:

[0005] The above-mentioned document, paragraph 0034, describes that "the waterproof and dustproof net has a plurality of mesh openings, each of which is arranged in an extended manner and arranged in a surrounding interval, the frame column passes through the mesh opening, the mesh opening has a wall, the wall surrounds and contacts the frame column; under the action of each mesh opening, the frame column is easy to penetrate, thereby facilitating the assembly between the frame column and the waterproof and dustproof net." Combined with the attached manual Figure 1 It can be seen that the waterproof and dustproof net needs to be installed on the grid through the mesh port. Since there are multiple mesh ports on one side of the waterproof and dustproof net, it is easy for water to penetrate into the outer wall of the grid from the inside of the mesh port. Although there is a sealing ring on the inner wall of the grid, if water accumulates on one side of the sealing ring for a long time, it will reduce the service life of the sealing ring and increase the risk of water seepage in the sealing ring.

[0006] Therefore, a waterproof and dustproof air filter is proposed to solve the above-mentioned drawbacks. Utility Model Content
