Technical Field

[0001] The utility model application relates to the technical field of filter screens, and in particular to a filter screen for air purification which is easy to clean. Background Art

[0002] Air purification refers to providing overall solutions such as sterilization and disinfection, dust reduction and haze removal, removal of harmful decoration residues and odors for various indoor environmental problems, improving living and working conditions, and promoting physical and mental health. Indoor environmental pollutants and pollution sources mainly include radioactive gases, mold, particulate matter, decoration residues, secondhand smoke, etc.

[0003] When an air purifier is in use, there are generally several combined filters inside. After the internal filters have been filtering for a period of time, they need to be taken out and cleaned to avoid clogging. However, since most of the existing filters are fixed on the support frame, they need to be cleaned by brushing after being taken out. However, brushing can easily cause the filters to become fuzzy or even damage the filters, reducing the service life of the filters. Summary of the invention

[0007] Furthermore, a handle is fixed in the middle of the top surface of the rear support frame, positioning blocks are symmetrically fixed to the front sides of the rear support frames on both sides of the front support frame, and positioning grooves cooperating with the positioning blocks are symmetrically opened on both sides of the front support frame.

[0008] Furthermore, the fixed convex frame and the fixed groove are both configured as rectangles that match the filter body and the rear support frame, and the edges of the fixed convex frame away from the front support frame are both configured as arcs.

[0009] Furthermore, a sealing pad is glued and fixed to the rear side of the front support frame outside the fixed convex frame, and the sealing pad is set to a rectangle that matches the front support frame and the fixed convex frame.

[0010] Furthermore, the rear support frame at the four corners on the rear side of the fixing groove is provided with fixing holes that cooperate with the fixing screws, and the width of the fixing screws is greater than the sum of the widths of the filter body, the fixing nut and the fixing holes.

[0011] Furthermore, a support ring gasket is fixed to the inner ring of the filter body outside the fixing screw, the thickness of the support ring gasket is smaller than the thickness of the fixing convex frame, and the support ring gasket is arranged in a ring shape that cooperates with the fixing screw.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. In the utility model, through the detachable design between the filter body and the front and rear support frames, the filter body can be separated and rubbed during cleaning to avoid fluffing or damage caused by brushing, thereby solving the problem that the existing air purification filter is easily damaged and fluffed during cleaning, and greatly improving the service life of the filter.

[0014] 2. In the utility model, the filter is fixed by overall clamping and partial interlacing to ensure the stability and firmness of the connection between the filter and the front and rear support frames during installation, thereby ensuring the filtering effect of the filter and also ensuring the convenience of assembling the filter.
