Example 1

Referring to fig. 1 to 3, in a preferred embodiment of the present invention, the air filter includes a frame 100 and a filter element 200, the frame 100 includes a frame main body 160 and a first fixing plate 140, the first fixing plate 140 is partially fixed on a back surface of the frame main body 160, a filter element pressing plate 300 for pressing the filter element 200 is partially detachably connected to a front surface of the frame main body 160, the first fixing plate 140 and the filter element pressing plate 300 define an open cavity, and the filter element 200 is installed in the cavity.

The filter screen in the prior art is split into the detachable design of the frame 100 and the filter element 200 from the original integrated design of the frame 100 and the filter element 200, so that the frame 100 can be repeatedly utilized to achieve the effect of reducing the cost. The above components are described in further detail below.

As shown in fig. 1, the bezel 100 includes a bezel main body 160, a first fixing plate 140, a slot 130, a second fixing plate 150, and a third fixing plate 180.

Specifically, the bezel 100 has an end side 110 and a side 120, the end side 110 being shorter in length than the side 120. Such a frame 100 is suitable for a filter cartridge 200 having a relatively large thickness, and the filter cartridge 200 is installed in the frame 100 in a vertical design.

The bezel body 160 includes a first sub-board 161, a second sub-board 162, a third sub-board 163, and a fourth sub-board 164. The first sub-board 161, the second sub-board 162, the third sub-board 163 and the fourth sub-board 164 are sequentially connected end to form a square frame structure. The first sub-plate 161 and the third sub-plate 163 have short lengths and are end sides 110. The second sub-board 162 and the fourth sub-board 164 have a long length, which is the side 120.

In order to enhance the structural stability of the bezel body 160, a reinforcing bar 170 is further included. Two ends of the reinforcing bar 170 are fixedly connected with the middle portions of the second sub-board 162 and the fourth sub-board 164 respectively.

The bezel main body 160 has a front surface and a rear surface, and one surface for mounting and dismounting is the front surface, and the other surface opposite thereto is the rear surface.

The first fixing plate 140 is elongated and is fixedly mounted on the back surface of the bezel main body 160. In the present embodiment, the first fixing plate 140 extends along the length direction of the end side 110. Specifically, there are two first fixing plates 140, which are fixedly connected to the first sub-plate 161 and the third sub-plate 163, respectively. Both ends of the filter cartridge 200 may be placed on the first fixing plate 140, thereby restricting the filter cartridge 200 within the bezel body 160 from moving toward the rear of the bezel body 160.

To facilitate the installation and aesthetics of the filter cartridge 200, as shown in fig. 1, the end side 110 or side 120 of the rim 100 is provided with a slot 130. The slot 130 extends along the length direction of the side 120, and the side of the filter element 200 is inserted into the slot 130. Specifically, the bezel 100 further includes a second fixing plate 150. The second fixing plate 150 extends along the longitudinal direction of the side 120, and the locking groove 130 is formed between the second fixing plate 150 and the second sub-plate 162 and the fourth sub-plate 164 of the bezel 100. In order to facilitate the installation of the side edge of the filter cartridge 200 into the locking groove 130, the second fixing plate 150 is provided with a guide plate 152 inclined in a direction away from the locking groove 130.

The front surface of the frame main body 160 is provided with a cartridge pressing plate 300 which presses the cartridge 200 to restrict the cartridge 200 in the frame main body 160 from moving toward the front surface of the frame main body 160. As shown in fig. 1, a third fixing plate 180 is fixed to the side 120 of the front surface of the bezel main body 160. The third fixing plate 180 is elongated and extends along the longitudinal direction of the side 120. The cartridge pressing plate 300 is detachably coupled to the third fixing plate 180.

As shown in fig. 2 and 3, the cartridge compression plate 300 is made of an elastic material, has an elastic deformation property, and is snap-fitted to the third fixing plate 180. The cartridge compression plate 300 is detachably connected to the frame 100, so that the cartridge 200 can be conveniently replaced from the front of the frame 100. The frame 100 can be reused, which is significant for reducing the cost.

Example 2

Referring to fig. 4 to 6, the air filter net according to another preferred embodiment of the present invention is substantially the same as that of embodiment 1, except that the first fixing plate 140 is disposed on the side 120 and extends along the length direction of the side 120. Meanwhile, the catching groove 130 and the second fixing plate 150 extend in a length direction of the end side 110. The air filter is suitable for a filter element 200 having a small thickness, as shown in fig. 5 and 6, in which the filter element 200 is installed in the frame 100 in a horizontal design.

As shown in fig. 4, the third fixing plate 180 is fixedly disposed at the end side 110 of the rim body 160, and the cartridge pressing plate 300 and the third fixing plate 180 are detachably coupled together by a fastening member 340.

Specifically, the filter element compression plate 300 is substantially "U" shaped and includes a first filter element compression sub-plate 310 and a second filter element compression sub-plate (not shown) that are vertically connected to each other. The first filter element pressing sub-plate 310 is pressed on the filter element 200, and the second filter element pressing sub-plate and the third fixing plate 180 are detachably connected together through fasteners 340 such as screws. Preferably, as shown in fig. 4, the third fixing plate 180 is substantially "U" shaped, forming a first relief hole 165 to relieve the fastener 340. The second fixing plate 150 is provided with a second avoiding hole 151 for avoiding the fastening member 340.

The foregoing is only a preferred embodiment of the present invention, and many variations in the detailed description and the application range can be made by those skilled in the art without departing from the spirit of the present invention, and all changes that fall within the protective scope of the utility model are therefore considered to be within the scope of the utility model.
