[0026] The following is combined with Figure 1-7 This application is described in further detail.

[0027] The present application discloses a vortex blower fan filter. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, a vortex blower fan filter includes a fan bracket 1, a first snap-in tongue 101 is fixedly provided on one side of the fan bracket 1, the first snap-in tongue 101 is arranged on the outer ring of one side of the fan bracket 1, the inner diameter of the first snap-in tongue 101 is greater than the outer diameter of the second snap-in tongue 201, a second snap-in tongue 201 is fixedly provided on one side of the fan protective cover 2, the second snap-in tongue 201 is arranged on the inner ring of one side of the fan protective cover 2, the middle outer surface of the second snap-in tongue 201 is slidably connected with the middle inner wall of the first snap-in tongue 101, and the middle outer surface of the second snap-in tongue 201 is inserted into the middle inner wall of the first snap-in tongue 101, so that the fan protective cover 2 can be aligned with the fan bracket 1 more conveniently and quickly, and the fixation between the fan bracket 1 and the fan protective cover 2 is convenient.

[0028] See also Figure 1The mounting hole on one side of the fan bracket 1 is fixedly connected to the mounting hole on one side of the fan protective cover 2 by means of mounting bolts. The fan protective cover 2 and the fan bracket 1 are both made of plastic, which saves production costs, reduces production cycles, and improves the economic efficiency of use. The mounting hole on the inner wall of the middle part of the fan protective cover 2 is fixedly connected to the mounting hole on one side of the fan 3 by means of mounting bolts.

[0029] See also Figure 3 A turbofan blade 301 is provided on the outer surface of the middle part of the fan 3, and one side of the turbofan blade 301 is fixedly connected to the inner wall of the middle part of the wind guide wheel 303. The wind guide wheel 303 is horn-shaped. The inner diameter of the side of the wind guide wheel 303 close to the fan bracket 1 is smaller than the inner diameter of the side of the wind guide wheel 303 close to the fan protective cover 2. The horn-shaped setting of the wind guide wheel 303 can diffuse the wind generated by the fan 3, so that the wind generated by the fan 3 can be completely blown on the filter cotton, avoiding the dead angle of the filter cotton causing dust accumulation. A muffler tooth 302 is provided on the blade of the turbofan blade 302 close to the fan protective cover 2. The muffler tooth 302 is V-shaped. The turbofan blade 302 and the wind guide wheel 302 are made of plastic as a whole, which reduces the influence of wind pressure on them, and the muffler tooth 302 provided on the blade of the turbofan blade 302 can reduce the noise generated when the turbofan blade 302 rotates.

[0030] See also Figure 1 The mounting hole on one side of the fan protective cover 2 is fixedly connected to the mounting hole on one side of the filter cover 4 through a mounting bolt. The inner wall in the middle of the filter cover 4 is slidably connected to the outer surface in the middle of the filter cotton 6. The filter cotton 6 is square in shape and has a full-open hole. The full-open hole setting of the square filter cotton 6 improves the permeability of the wind diffused by the fan 3 and reduces the influence of the filter cotton on the air volume generated by the fan 3. The card slot at one end of one side of the filter cover 4 is rotatably connected to the panel rotation pin at one end of the panel 5.

[0031] See also Figure 1 A locking buckle 401 is provided on one side of the filter cover 4, and one end of the locking buckle 401 is clamped with one end of the panel 5 through the panel switch 501. A limiting tongue 502 is fixedly provided on one end of the panel 5, and one end of the limiting tongue 502 is clamped with one end of the limiting hook 402. The other end of the limiting hook 402 is fixedly provided on one end of the filter cover 4. The limiting tongue 502 cooperates with the limiting hook 402 to limit the swing of the panel 5, so as to prevent the panel 5 from having a large swing and falling off when it is opened.

[0032] The implementation principle of one embodiment of the present application is: through the operation of the fan 3, the turbofan blades 301 are rotated to blow air, and the wind generated by the turbofan blades 301 will be diffused through the guide wheel 303, so that the wind generated by the fan 3 when working can be completely blown on the filter cotton 6, and the fully open holes of the filter cotton 6 allow the wind generated by the fan 3 to pass through all corners of the filter cotton 6 and be blown out through the panel 5. When the filter cotton 6 needs to be cleaned or replaced, the panel switch 501 set on the panel 5 is pressed to release the restriction of the locking buckle 401 on the panel 5, so that the panel 5 is opened. When the panel 5 is opened to a certain extent, the limiting tongue 502 will fix the angle of the panel 5 through the limiting hook 402, and the filter cotton 6 is taken out from the filter cover 4 for cleaning and replacement of new filter cotton 6.

[0033] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
