[0002] The so-called car seat is the seat for sitting in the car; car seats can be divided into split seats and long seats according to their shapes; they can be divided into fixed, detachable and adjustable types according to their functions. When people sit in the seat for a long time while driving, their buttocks and backs often sweat, causing discomfort to the driver.

[0003] In order to solve the above problems, a Chinese patent with publication number CN216709098U discloses a car seat ventilation device, including a base, a connecting plate fixedly arranged on the upper end of the base, two correspondingly distributed baffles fixedly arranged on the upper end of the connecting plate, a hip ventilation pad fixedly arranged on the top of the two baffles, a back support plate fixedly arranged on the side wall of the base, a connecting frame fixedly arranged on the upper end of the back support plate, a slot opened at the bottom of the base, a fan fixedly arranged inside the slot, a second connecting pipe connected to the output end of the fan, a third connecting pipe connected to the second connecting pipe, and a transverse pipe connected to the end of the third connecting pipe away from the second connecting pipe. Through the cooperation of the fan, the second connecting pipe and the hip ventilation pad, the seat can be ventilated to keep the driver dry.

[0004] The above patent has the following problems during actual use: 1. The dust particles in the air inside the car can be filtered and collected through the cooperation between the dust storage box and the dust filter, but as the use time increases, more and more dust particles will adhere to the dust filter, causing the dust filter to be blocked, thereby affecting the filtering effect; 2. When the dust filter needs to be cleaned, the dust storage box needs to be completely taken out before the dust filter can be cleaned, thereby ensuring the filtering effect of the dust filter, that is, the dust filter needs to be cleaned regularly, which is cumbersome. Summary of the invention

[0005] The present invention is intended to provide a vehicle seat ventilation device to solve the problem that dust particles adhere to the dust filter in the existing ventilation device and block the dust filter.

[0006] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a car seat ventilation device, including a seat body and a filter net, a chamber is provided in the seat body, an air outlet is provided in the chamber, and the filter net is fixedly connected in the chamber; a rotating shaft is rotatably connected in the chamber, and a plurality of first brush bristle layers are equidistantly provided on the rotating shaft along the axial direction of the rotating shaft, and the free end of the first brush bristle layer passes through the filter net; a storage groove is provided on the side wall of the base body, and a recycling box with a top opening is slidably connected in the storage groove, and the recycling box is communicated with the chamber; it also includes an introduction mechanism for introducing outside air into the chamber and a driving mechanism for driving the rotating shaft to rotate.

[0007] The principles and advantages of this solution are:

[0008] 1. In this scheme, the air passes through the filter and is discharged from the air outlet. The filter can filter the dust particles in the air, thereby removing dust from the air.

[0009] 2. With this solution, as the filtering time increases, more and more dust particles will adhere to the filter and cause blockage. During the rotation of the shaft, the shaft drives the first brush layer to rotate synchronously, and the first brush layer is used to clean the filter to avoid blockage of the filter, thereby ensuring the filtering effect. Moreover, the filter can be continuously cleaned without disassembling and removing it, which reduces the operation and makes the cleaning of the filter easier.

[0010] 3. All the dust cleaned by this solution is collected in the recycling box. By moving the recycling box out of the storage tank, the dust particles in the recycling box can be processed for the next use.

[0046] The specific implementation process is as follows:

[0047] When in use, the vacuum pump 30 is started to introduce external air into the chamber 12 through the air inlet pipe 31 and the air outlet pipe 32, so that the air is located on the left side of the filter 11; the air passes through the filter 11 and is discharged from the air outlet 13, and the filter 11 can filter the dust particles in the air. As the filtering time increases, more and more dust particles will adhere to the filter 11, causing it to be blocked.

[0050] During the period when the first bristle layer 21 is rotated by the rotating shaft 20, the first bristle layer 21 acts on the sponge layer to clean the first bristle layer 21; due to the mixture of water and dust particles on the first bristle layer 21, adjacent bristles may stick together, and the rotating shaft 20 drives the first bristle layer 21 to continue to rotate, so that the first bristle layer 21 is blocked by the sponge layer and bends, and the inclined rod 62 is used to pass through the first bristle layer 21 to clean and comb the first bristle layer 21, so that the inclined rod 62 can act on the middle position and free end position of the first combing bristle layer, and the cleaning and combing effects are better, thereby avoiding the bristles in the first bristle layer 21 from sticking and affecting the cleaning effect of the filter 11; and the clean water flowing along the path of the inclined rod 62 can act on the first bristle layer 21 before and after combing, which can enhance the cleaning effect of the first bristle layer 21, and at the same time avoid the adjacent bristles in the first bristle layer 21 after combing from sticking.

[0051] During the vertical reciprocating motion of the C-shaped frame 41, the C-shaped frame 41 will also drive the vertical block 40 to move vertically, and the vertical block 40 will drive the lifting block 50 and the second brush layer 51 to move vertically, and then use the second brush layer to clean the filter screen 11, further enhancing the cleaning effect of the filter screen 11.

[0052] When the rotating shaft 20 drives the first bristle layer 21 to rotate to the left side, the first bristle layer 21 is located directly below the combing rod 57; at this time, the lifting block 50 moves downward, and the lifting block 50 drives the movable rod 53 to move downward, so that the movable rod 53 drives the combing rod 57 to pass through the first bristle layer 21; during the downward movement of the movable rod 53, the movable rod 53 moves along the path of the inclined groove 52, so that the movable rod 53 can also drive the transverse block 56 to move transversely in the transverse groove 55, and then the movable rod 53 drives the combing rod 57 to move synchronously transversely, that is, the combing rod 57 can be used to clean and comb the first bristle layer 21, further enhancing the cleaning effect of the first bristle layer 21, and at the same time, it can also avoid the bristles in the first bristle layer 21 from sticking and affecting the cleaning effect of the filter 11.

[0053] The dust particles and the mixture of dust particles and water cleaned by the first bristle layer 21 and the second bristle layer 51 are collected in the recycling box 15. The recycling box 15 is moved out of the storage tank 14 by the handle 16 to process the dust particles and the mixture of dust particles and water in the recycling box 15 for next use.
