Technical Field

[0001] This utility model relates to the field of filter technology, specifically to a plateless high-efficiency filter. Background Technology

[0002] As people become more environmentally conscious, their demands for air cleanliness are also increasing. As a result, various air purifiers have emerged. Based on the air purification requirements of different indoor environments, filters are usually divided into coarse, medium, and high efficiency filters. Currently, outdoor air contains a large number of dust and impurity particles, leading to a decline in air quality. When air enters the room, it needs to be properly filtered to improve air quality.

[0003] Nowadays, air purifiers mostly use plate or bag filters, which take up a lot of space. This makes them inconvenient to move, install and maintain when used indoors. In addition, the uneven distribution of filter elements makes it difficult to maintain a stable airflow at the inlet and outlet, thus affecting the uniformity of airflow.

[0004] To address the aforementioned issues, a diaphragmless high-efficiency filter is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a plateless high-efficiency filter, which solves the problems in the background art where the filters used in current air purifiers are mostly plate or bag filters, which occupy a lot of space, making them inconvenient to move, install and maintain when used indoors. In addition, the filter element distribution is uneven, and the air volume at the inlet and outlet is difficult to maintain, thus affecting the uniformity of airflow.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a plateless high-efficiency filter, comprising an aluminum profile frame, a filter mechanism disposed inside the aluminum profile frame, a gasket pressing member attached to one side of the filter mechanism, a metal protective mesh threadedly fixed to the gasket pressing member and the side of the aluminum profile frame, two sets of metal protective mesh, each metal protective mesh comprising a protective mesh frame and a protective mesh member fixedly disposed in the middle of the protective mesh frame, the filter mechanism comprising a first rubber sealing gasket embedded in the aluminum profile frame, glass fiber filter paper attached to the first rubber sealing gasket, and a second rubber sealing gasket movably disposed on one side of the glass fiber filter paper, the gasket pressing member being pressed against one side of the second rubber sealing gasket.

[0007] Preferably, the aluminum profile outer frame includes an outer frame plate and a positioning thickened inner wall fixedly disposed within the outer frame plate.

[0008] Preferably, the side of the first rubber gasket that is in contact with the glass fiber filter paper is provided with horizontal teeth, and the side of the second rubber gasket that is in contact with the glass fiber filter paper is provided with vertical teeth.

[0009] Preferably, the glass fiber filter paper includes a thickened pressing paper pressed between the horizontal and vertical teeth, and the thickened pressing paper has folded paper arranged side by side inside.

[0010] Preferably, the sides of the folded paper are sealed with side sealing paper side by side.

[0011] Preferably, the gasket pressing component includes an insert that fits onto one side of the second rubber sealing gasket, and the insert is embedded inside the outer frame plate.

[0012] Preferably, the gasket pressing component further includes an outer plate fixedly connected to one side of the embedded component.

[0013] Preferably, the metal protective net also includes fixing screws at the four corners of the protective net frame, with fixing screws on one side used to insert the outer plate, the protective net frame and the outer frame plate, and fixing screws on the other side used to insert the outer frame plate and the protective net frame.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. The present invention provides a plateless high-efficiency filter, which uses double-sided metal mesh on the air inlet and outlet surfaces. The mesh frame is used for side sealing, and the mesh is used for ventilation. The metal mesh is made of metal material, which can maintain stable air volume and thus achieve high airflow uniformity. This solves the problem of uneven filter distribution and difficulty in maintaining stable air volume at the inlet and outlet in current air purifiers, thus affecting airflow uniformity.

[0016] 2. This utility model provides a plateless high-efficiency filter, which is easy to install without professional skills by stacking aluminum profile frame, filter mechanism and gasket pressing parts. It is not easily damaged during use and has low maintenance cost. Moreover, by changing the thickness of aluminum profile frame, plateless high-efficiency filters of different thicknesses can be manufactured to adapt to different installation spaces. The surface of aluminum profile frame and metal guard needs to be anodized to improve the surface performance of the filter and improve its corrosion resistance, wear resistance and oxidation resistance, thereby extending the service life of the filter. It solves the problem that the filters used in current air purifiers are mostly plate or bag filters, which occupy a lot of space and are inconvenient to transport, install and maintain when used indoors.

Furthermore, by changing the thickness of the aluminum profile outer frame 1, different thicknesses of plateless high-efficiency filters can be manufactured to adapt to different installation spaces. The surfaces of the aluminum profile outer frame 1 and the metal mesh 4 need to be anodized to improve the surface performance of the filter, enhance its corrosion resistance, wear resistance and oxidation resistance, thereby extending the service life of the filter.

[0027] The present invention will be further described below with reference to the embodiments.
