[0046] Specifically, in this embodiment, Figures 6 to 8As shown, the frame 210 is provided with a limit insert 215, and the limit insert 215 is located at the rear side of the frame 210; the face shell 100 is provided with a limit slot 150, and the limit insert 215 is inserted into the corresponding limit slot 150, and the limit slot 150 can prevent the corresponding limit insert 215 from moving upward. In this setting form, when the filter assembly 200 is assembled to the face shell 100, the limit insert 215 can be inserted into the corresponding limit slot 150 to preliminarily position the frame 210, and then the buckle can be inserted into the corresponding card hole to complete the installation of the frame 210 and the filter assembly 200. In addition, the plug-in connection method is adopted on the rear side, which can further improve the efficiency of disassembly and assembly.

[0047] Specifically, in this embodiment, the buckle is arranged on the front side and the front ends of both sides of the frame 210, and the limiting insert 215 is arranged on the rear side of the frame 210; the clamping hole is arranged on the front side and the front ends of both sides of the face shell 100 and is arranged corresponding to the buckle; the limiting slot 150 is arranged on the rear side of the face shell 100 and is arranged corresponding to the limiting insert 215. Under this arrangement, when performing the assembly operation, it is convenient for the operator to operate in front of the face shell 100.

[0048] It should be noted that in other embodiments of the present application, the setting positions of the buckles and the holes, as well as the setting positions of the limiting insert 215 and the limiting slot 150 are not limited to the above-mentioned positions. For example, the limiting insert 215 and the limiting slot 150 can also be set on the front side, while the buckles and the holes can be set on the rear side or the rear ends of both sides. When performing the assembly operation, in order to facilitate the operation, the operator can operate at the rear of the face shell 100.

[0049] Specifically, in this embodiment, Figure 3 , Figure 7 and Figure 8 As shown, the buckle includes a hard buckle, and according to the setting position, the hard buckle includes a front hard buckle 211 and a side hard buckle 212, the front hard buckle 211 is set on the front side of the frame 210, and the side hard buckle 212 is set at the front ends of both sides of the frame 210; the clamping hole includes a first clamping hole 120 and a second clamping hole 130, the first clamping hole 120 is set corresponding to the front hard buckle 211, and the second clamping hole 130 is set corresponding to the side hard buckle 212; the front hard buckle 211 is clamped in the corresponding first clamping hole 120, thereby fixing the front side of the frame 210 to the face shell 100; the side hard buckle 212 is clamped in the corresponding second clamping hole 130, thereby fixing the left front end and the right front end of the frame 210 to the face shell 100.

[0050] In addition, the buckle also includes a spring buckle 213, which is arranged on the front side of the frame 210; the clamping hole also includes a third clamping hole 140, and the spring buckle 213 is clamped in the corresponding third clamping hole 140, and together with the front hard buckle 211, the frame 210 is fixed to the face shell 100. In this way, the connection between the frame 210 and the entire filter assembly 200 and the face shell 100 is more firm and reliable.

[0051] More specifically, in this embodiment, if Figure 2 , Figure 4 and Fig. 9 As shown, the spring buckle 213 is a U-shaped spring buckle that can be deformed forward and backward, and the free end of the U-shaped spring buckle is provided with a clamping surface 214; the third clamping hole 140 is provided with a clamping rib 141; the U-shaped spring buckle can be easily inserted into the third clamping hole 140 by compressing it, and after the U-shaped spring buckle is released, the free end of the U-shaped spring buckle moves to the hole wall of the third clamping hole 140 in the direction of reset and is still in a compressed and deformed state, and the clamping surface 214 moves to the bottom of the clamping rib 141, so that the clamping rib 141 can prevent the U-shaped spring buckle from escaping upward from the third clamping hole 140. Under this setting form, the elastic force of the spring buckle 213 resetting can increase the tightness of its connection with the third clamping hole 140 in the front-to-back direction, and the clamping rib 141 can limit the upward movement of the spring buckle 213 by blocking the clamping surface 214, thereby further improving the connection reliability between the frame 210 and the face shell 100.

[0052] Specifically, in this embodiment, Figure 7 As shown, there are two reels 220 , which are respectively disposed at two opposite ends of the frame 210 and are parallel to each other; two ends of the filter screen 230 are respectively fixedly disposed on one of the reels 220 .

[0057] Specifically, in this embodiment, the base 400 is provided with an electric control box, and the drive motor 310 is connected to the circuit board in the electric control box. In this arrangement, the drive motor 310 and the electric control box are both arranged on the base 400, so when the filter assembly 200 is disassembled, there is no need to cut off the connection between the drive motor 310 and the circuit board; when the filter assembly 200 is installed, there is no need to reconnect the connection between the drive motor 310 and the circuit board, thereby ensuring the convenience of disassembling and assembling the filter assembly 200.

[0058] Specifically, in this embodiment, Fig.11As shown, the base 400 is provided with a wire pass card 410, and the wire pass card 410 fixes the connecting wires between the drive motor 310 and the circuit board to the base 400. In this arrangement, the wire pass card 410 binds and fixes the connecting wires between the drive motor 310 and the circuit board, which can effectively prevent other components from interfering with it, thereby ensuring a reliable connection between the drive motor 310 and the circuit board. Of course, it can also effectively prevent the connecting wires from interfering with other components.

[0059] Specifically, in this embodiment, Fig.11 As shown, in addition to the driving motor 310 and the driving gear 320, the driving assembly also includes a shield 330. The shield 330 is fixedly disposed on the base 400, and the shield is disposed on the side of the driving gear 320 away from the driving motor 310, and is used to block the driving gear 320 from moving axially away from the driving motor 310, and plays an axial limiting role on the driving gear 320, which can ensure the stable meshing transmission between the driving gear 320 and the driven gear 221.
