DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] See also Figure 1-6 The utility model provides a technical solution: a fan with a filtering function, comprising: a filter box 1, a motor 2, a protective cover 3, a rotating rod 4, a protrusion 5, a torsion spring 6, a first fan blade 7, a mounting frame 8, a second fan blade 9, a brush plate 10, a scraper 11, a filter plate 12, a sliding rod 13, a hinged rod 14, a block 15, a spring 16, an air outlet pipe 17 and an activated carbon plate 18.

[0030] When using the fan with filtering function, first Figure 1 , Figure 4 and Figure 5 As shown, the motor 2 is fixedly installed at the right end of the filter box 1, the protective cover 3 is fitted at the left end of the filter box 1, and the upper part of the protective cover 3 is rotatably connected to the filter box 1, and the protective cover 3 is a hollow structure, a rotating rod 4 is rotatably installed inside the lower end of the protective cover 3, and a torsion spring 6 is sleeved on the outer side of the left part of the rotating rod 4, and the two ends of the torsion spring 6 are respectively fixed to the protective cover 3 and the rotating rod 4, a convex block 5 is installed on the outer side of the right end of the rotating rod 4, and the right part of the rotating rod 4 and the convex block 5 are both rotated in the groove opened inside the filter box 1;

[0031] When it is necessary to open the protective cover 3, hold the left end of the rotating rod 4 and rotate it. At this time, the torsion spring 6 undergoes elastic deformation, and the rotating rod 4 drives the protrusion 5 to rotate ninety degrees. The rotating rod 4 is pulled outward so that the rotating rod 4 and the protrusion 5 leave the interior of the filter box 1 at the same time. After the protective cover 3 is rotated open, it is convenient to observe the situation inside the filter box 1. When the protective cover 3 is closed, the rotating rod 4 is rotated to push the rotating rod 4 and the protrusion 5 into the filter box 1. Then, the rotating rod 4 is released and the protrusion 5 is rotated and stuck into the arc groove in the filter box 1 under the elastic action of the torsion spring 6, completing the fixing of the protective cover 3 to the filter box 1. This installation method saves the energy and time required for opening and closing the protective cover 3, and the connection is stable.

[0032] like Figure 1 , Figure 2 , Figure 3 and Figure 6As shown, the middle part of the first blade 7 is fixedly connected to the output end of the motor 2, and the first blade 7 is arranged on the right side of the filter plate 12, the first blade 7 is rotatably connected to the inside of the filter box 1, the mounting frame 8 is fixedly installed in the inside of the filter box 1 by expansion bolts, the second blade 9 is rotatably connected to the left side of the middle part of the mounting frame 8, and the right end of the shaft rod of the second blade 9 is fixedly connected to the brush plate 10, the right side of the brush plate 10 is provided with a filter plate 12, and the bristles of the right part of the brush plate 10 are attached to the left side of the filter plate 12, the brush plate 10 is rotatably connected to the inner side of the mounting frame 8 through the second blade 9, the lower end of the scraper 11 is fixedly connected to the mounting frame 8, and the mounting frame 8 and the lower part of the filter box 1 are both provided with openings, the left part of the scraper 11 is evenly arranged with sharp teeth, and the filter plate 12 is slidably connected to the inner side of the filter box 1;

[0033] When the fan is working, the motor 2 is turned on to rotate the first blade 7, and the first blade 7 sucks the air outside the filter box 1 into the inside of the filter box 1. At this time, the second blade 9 is affected by the wind and rotates, and the second blade 9 drives the brush plate 10 to rotate on the left side of the filter plate 12, and uses the bristles to scrape the fluff adhering to the filter plate 12 onto the bristles. When the brush plate 10 rotates, it slides over the scraper 11 intermittently, and the fluff is scraped by the scraper 11 and discharged from the inside of the filter box 1 from the opening, which can automatically clean the fluff adhering to the filter plate 12, avoid the filter plate 12 from being blocked and reducing its ventilation and filtering effect, and reduce the frequency of manual cleaning;

[0034] The slide bar 13 is slidably connected in the arc-shaped groove opened inside the filter box 1, and the inner end of the slide bar 13 is protruding and arranged on the outside of the filter box 1, the outer end of the slide bar 13 is rotatably connected with the hinge rod 14, and the other end of the hinge rod 14 is rotatably connected with the clamping block 15, the clamping block 15 is slidably connected in the cavity opened inside the filter box 1, and the clamping block 15 is clamped and connected with the groove opened on the outer circle of the filter plate 12, the clamping block 15 is arranged in an annular shape at equal angles along the center point of the filter plate 12, and the inner side of the slide bar 13 is connected to the filter box 1 through the spring 16;

[0035] Pulling the slide bar 13 causes the spring 16 to be squeezed and elastically deformed, and the slide bar 13 pulls the hinged rod 14 to flip in the cavity of the filter box 1, and the hinged rod 14 pulls the block 15 to slide outward, thereby releasing the connection between the block 15 and the filter plate 12, and the filter plate 12 can be taken out of the fan for cleaning and replacement. This installation method is simple and stable, and is convenient for quick disassembly and assembly of the filter plate 12, saving working time. The wind is filtered by the filter plate 12 and discharged from the air outlet pipe 17. When discharged, the pressurized wind passes through the activated carbon plate 18 for secondary filtration, and the odor contained in the air is adsorbed by the activated carbon plate 18, so as to avoid the odor mixed in the discharged wind to damage the quality of the surrounding environment and cause discomfort to people.
