Detailed ways

Below in conjunction with accompanying drawing and embodiment, the utility model is further described:

Embodiment 1: Referring to Figures 1 and 2, a high-performance filter includes a casing 1 and a filter element arranged in the casing. The rear side of the casing 1 is provided with a suction fan 2, and the filter element includes a plurality of filters. A filter screen 3, the filter screen includes a primary filter screen 4, an activated carbon filter screen 5, a photocatalyst filter screen 6 and a HEPA filter screen 7 arranged in sequence from front to back. Installation position 8, a plurality of sets of the filter screens are respectively installed in one set of the installation positions, the top of the installation position is communicated with the top of the shell, and the bottom of the filter screen passes through the top of the shell inserted and installed in the installation position;

Two sets of limiting mechanisms 9 are arranged in each set of the installation positions, and the two sets of limit mechanisms limit the filter screen to the installation positions;

The two sets of the limiting mechanisms are respectively arranged on the left and right sides of the installation position. The limiting mechanisms include two sets of symmetrically arranged arc-shaped elastic sheets 10, and the two sets of the arc-shaped elastic sheets are respectively installed on the installation position. On the inner wall of the front side and the inner wall of the rear side, the convex ends of the two sets of arc-shaped elastic pieces are arranged opposite to each other, a clamping distance is set between the two sets of the arc-shaped elastic pieces, and the filter screen is clamped on the clamping within the distance.

In this embodiment, when the suction fan is sucking air, multiple groups of air enter from the front side of the housing, pass through multiple sets of filter screens in sequence, and then are sent out through the suction fan. In this process, the primary filter and activated carbon filter are used for preliminary filtration, the photocatalyst filter is used for sterilization, and the HEPA filter is used for high-performance filtration to achieve rapid air filtration and high-quality filtration. Among them, the primary filter and activated carbon filter at the front end need to filter some impurities such as particulate matter, and are most likely to be blocked. Therefore, the frequency of replacement is more likely to be saturated than the photocatalyst filter and HEPA filter at the back end. Therefore, The replacement frequency of the two sets of filters at the front end is higher. When it needs to be replaced, directly pull the filter to be replaced from the top of the installation position upwards, so that the curved shrapnel recovers, and then remove the filter to be replaced from the installation position. Insert the top of the shrapnel, use the filter screen to compress the two sets of arc-shaped shrapnel, and use the elastic deformation strength of the two sets of arc-shaped shrapnel to press the filter screen to prevent displacement and deformation when subjected to wind, and to ensure the stability and quality of the filter. In addition, the arc-shaped shrapnel is adopted, which is an arc-shaped structure. When the filter screen moves up and down, it can prevent the filter screen from being scratched, and ensure the filter screen replacement and use quality.

Referring to Figures 1 and 2, the top of the arc-shaped elastic piece is connected to the installation position through a bolt 11, the arc-shaped elastic piece is inclined inwardly from bottom to top, and the bottom of the arc-shaped elastic piece is provided with a curling edge 12 , the curling edge is disposed toward the inner wall corresponding to the installation position, and the outer end of the curling edge constitutes a convex end.

In this way, when the filter screen moves downward, the bottom of the arc-shaped shrapnel is squeezed and deformed inward, and the arc-shaped shrapnel will not scratch the filter screen. When the filter screen is pulled up and removed, the crimping will not scratch the filter screen, so that the damaged filter screen exists in the installation position, which will not affect the installation of the subsequent filter screen.

Referring to FIG. 1 , a cavity 13 is provided inside the casing, and an air inlet 14 and an air outlet 15 are respectively provided on the front side and the rear side of the casing. The cavities are communicated with each other, the middle part of the filter screen is arranged in the cavity, and the suction fan is arranged at the air outlet.

The installation position is arranged on the inner wall of the cavity, and the limiting mechanisms are arranged on the left and right sides of the cavity.

The top of the installation position communicates with the top surface of the housing.

At the same time, a cover plate 16 is provided on the top of the casing, and the cover plate is detachably installed on the top of the casing. When the filter screen needs to be installed, the cover plate can be opened and the filter screen can be replaced. After the replacement is completed, cover the cover on the top of the housing to block the top of the installation position, so that when the air is filtered, it enters from the air inlet, and uses multiple sets of filters to filter in sequence to realize the air filtration function.

Among them, a mark can be made on the top of the casing, and the mark can be made on the side of each group of installation positions, which can further prevent the filter screen from being installed in the wrong position.
