[0022] like Figures 1 to 4 As shown, a cleaning device for a vehicle air filter element of the present invention comprises a fixed bracket and a cleaning box 2 located above the fixed bracket; wherein, a take-in port 21 and an air inlet 22 are respectively provided on two oppositely arranged side walls of the cleaning box 2; the size of the take-in port 21 is determined according to the size of the air filter element 01, as long as it is ensured that the air filter element 01 can smoothly enter and exit the cleaning box 2 through the take-in port 21; a debris brushing device is provided at a position near the take-in port 21 in the cleaning box 2, and when the cleaning personnel put the air filter element 01 into the cleaning box 2 and contact and rub against the debris brushing device, dust and other debris on the air filter element 01 can be effectively brushed off; the cleaning box 2 peripheral device A suction fan 4 connected to the air suction port 22 is provided, and a dust filter 5 is installed at the air suction port 22. The suction fan 4 is controlled by the control box 7 on the cleaning box 2. In this way, when the suction fan 4 is started, under the action of the suction fan 4, air will enter the cleaning box 2 from the loading and unloading port 21 and be discharged from the air suction port 22 to form convection wind. The formed convection wind can further take away some debris on the air filter element 01, thereby improving the cleaning effect of the air filter element 01. In addition, since the air in the cleaning box 2 can only be discharged from the air suction port 22, and the dust filter 5 is provided at the air suction port 22, the dust in the cleaning box 2 is effectively prevented from flowing out with the air, thereby ensuring the cleanliness of the air outside the box.

[0023] It can be understood that the fixed support includes at least three pillars 1; each pillar 1 cooperates to stably support the cleaning box 2.

[0024] It is understandable that the dust filter element 5 is any existing air filter element such as a filter bag or a filter screen, and this is not limited thereto. The dust filter element 5 of this embodiment is preferably configured as a filter bag.

[0025] It is understandable that there is at least one suction port 22, and each suction port 22 needs to be located on the same side wall to facilitate the formation of convection wind; in this embodiment, the suction port 22 is preferably set to 2, and the center height of each suction port 22 is equal to the center height of the loading and unloading port 22.

[0026] It is understandable that the debris brushing device as a whole may be in various shapes such as a fan-shaped or flat-plate-shaped shape, and there is no limitation to this. In order to increase the contact area between the debris brushing device and the air filter element 01, the overall shape of the debris brushing device is preferably set to be a fan-shaped.

[0027] Specifically, the debris brushing device has the following two structures: the first structure is: the debris brushing device directly uses a fan-shaped brush, the radius of the fan-shaped brush can be determined according to the diameter of the air filter element; the fan-shaped brush encloses to form a shelf groove for holding the air filter element 01, which is convenient for temporarily placing the air filter element 01 during the cleaning process; the second structure is as follows: Figure 1 and Figure 2 As shown: the debris brushing device includes a plurality of roller brushes 61 arranged in a fan shape; the roller brushes 61 are rotatably installed in the cleaning box 2, and the roller brushes 61 together enclose a placement groove for placing the air filter element 01; the second structure is preferably used in this embodiment to achieve rolling brushing of debris on the air filter element 01, so as to avoid the brushed debris being locally accumulated on the debris brushing device and affecting the brushing effect of the debris brushing device.
