[0019] 4. The present invention provides multiple hammer blocks, so that the frequency of hammer contact with multiple end blocks is higher. At the same time, adjacent hammer blocks will also generate a certain degree of vibration when hammering each other. The vibration generated when the hammer blocks collide with each other will be transmitted to the blades through the air, causing the blades to vibrate as well, and enhancing the vibration effect of the filter when contacting the filter.

When disassembling, the disassembly plate 163 is pulled outward to drive the fastening piece 162 to rotate, so that the fastening piece 162 is separated from the notch 168, which facilitates the separation of the fastening strip 161 from the fastening groove 165.

[0034] like Figure 1-Figure 10 As shown, a rack 171 is provided on one side of the disassembly plate 163 facing the buckling member 162, and the buckling member 162 is provided with a disc-shaped structure at one end facing the disassembly plate 163 and has side teeth 172 on the outer wall, the side teeth 172 are meshed with the rack 171, and the buckling strip 161 is provided with a hook shape at one end facing the buckling groove 165.

[0035] like Figure 1-Figure 10 As shown, side panels 18 are symmetrically provided on both sides of the front outer frame 1, and the side panels 18 are slidably adapted to the strip groove 8. When the front outer frame 1 and the rear outer frame 2 are buckled together, a width adapted to the end frame 911 is left in the strip groove 8. The side panels 18 are provided to limit the end frame 911 and ensure the stability of the end frame 911 when sliding up and down.

[0036] Working principle: When the primary filter is simply cleaned, the latch 613 can be slid open to disengage the positioning connection between the top of the front mesh plate 511 and the front outer frame 1. At this time, the front mesh plate 511 can be pulled to rotate around the upper end of the latch 611 to open. At this time, the front mesh plate 511 and the front outer frame 1 are inclined at a certain angle. The staff can take an electrostatic plate 712 and slide it from top to bottom between the two side strips 711. The electrostatic plate 712 is limited by the two side strips 711, and then the front mesh plate 511 is re-fastened. The front mesh plate 511 is fixed to the front outer frame 1 by the latch 613. The electrostatic plate 712 is made of polypropylene, which is lightweight and durable. The effect of easy molding is suitable for making electrostatic dust absorption plates, and the outer wall of which is coated with an electrostatic coating, such as a conductive polymer or a carbon-based material. The coating can make the surface of the electrostatic plate 712 better able to absorb dust and particulate matter in the air, thereby improving the cleaning effect. At this time, the handle 11 exposed on the side wall of the rear outer frame 2 is rotated to drive the rotating shaft 912 to rotate, thereby driving the vibration wheel 913 on the rotating shaft 912 to rotate. During the rotation process, the edge of the vibration wheel 913 continuously strikes the part of the filter 3 protruding from the rear outer frame 2, which collects the most dust. When the filter 3 of this part is struck and lifted up to the electrostatic plate 712, the dust falling off the filter 3 flies away quickly under the action of static electricity. The filter 3 is moved toward the electrostatic plate 712 and firmly adsorbed on the electrostatic plate 712. By continuously rotating the handle 11, the filter 3 is driven to vibrate continuously, thereby achieving a good vibration dust removal effect of the filter 3. A vibration block 9133 is provided at the edge of the vibration wheel 913 through a first spring 9132. The first spring 9132 drives the vibration block 9133 to vibrate back and forth when squeezed, thereby enhancing the vibration effect of the filter 3 to a certain extent, so that the dust on the filter 3 can be better removed. Due to the limited number of rotating shafts 912, the filter 3 at each position cannot be knocked. The handle 11 can be pulled up and down while rotating the handle 11, so that the handle 11 and the vibration mechanism are moved up and down in the slide groove 10. Slide down to realize the vibration wheel 913 to knock on different upper and lower positions of the filter 3 to make it vibrate. After cleaning, repeat the above-mentioned opening and closing steps of the front mesh plate 511 to open the front mesh plate 511, take out the electrostatic plate 712 and then close it. In the above steps, there is no need to open the front outer frame 1 and the rear outer frame 2, so as to realize simple waterless cleaning of the internal filter 3. The operation is simple and more convenient to use. If the filter 3 needs to be replaced, the front outer frame 1 and the rear outer frame 2 can be opened, and the filter 3 can be slid out from the bottom to the top along the installation axis 4 to realize replacement. The vibration mechanism can realize sliding removal, and before the vibration mechanism is taken out, the handle 11 needs to be disassembled and separated from the end frame 911.
