[0025] Embodiment 1, as Figure 1 As shown,

[0026] A self-cleaning structure of an automobile air conditioning filter comprises a filter element housing 1, a filter element body 2 is installed in the filter element housing 1, a self-cleaning component is installed on the top of the filter element housing 1, and the self-cleaning component comprises, from top to bottom, a piezoelectric ceramic plate assembly 3, a mounting plate 4, a magnetic storage plate 5 and an adsorption plate 6, the piezoelectric ceramic plate assembly 3 is composed of a plurality of piezoelectric ceramic modules connected in parallel, which are electrically connected to the electronic components in the mounting plate 4, and a protective cover 7 is also installed on the top of the mounting plate 4. By utilizing the vibration generated during the driving of the car, the piezoelectric ceramic plate assembly 3 in the self-cleaning assembly at the top of the filter housing 1 is vibrated, and the generated electricity enters the magnetic storage plate 5, and then is converted by the magnetic storage plate 5 into magnetic force to provide power for adsorbing the dust on the filter body 2, so that the dust in the filter body 2 floats on the surface of the adsorption plate 6 of the filter body 2, and is adsorbed on the adsorption plate 6 when the car is stationary, so as to reduce the dust in the filter body 2 and improve the service life of the filter body 2, and only needs to clean the adsorption plate 6 regularly to clean a large amount of dust inside, wherein the rotating plate 4 includes an electric storage assembly, a controller and several spiral coils, the spiral coils are connected in series and spaced in parallel, the controller is electrically connected to the electric storage assembly, the spiral coil and the piezoelectric ceramic plate assembly 3 respectively, wherein the electric storage assembly is a lithium battery, the electricity generated by the piezoelectric ceramic plate assembly 3 is stored in the electric storage assembly through the controller, and the controller controls the power-on state of the spiral coil, so that when the car is stationary, there is also current passing through the spiral coil, so as to achieve the purpose of adsorbing the dust in the filter body 2 to the bottom of the adsorption plate 6.

[0027] Embodiment 2, as Figure 2As shown, since the adsorption plate 6 is a flat plate surface, most of the dust adsorbed by the car during driving will fall onto the filter element body 2. For this reason, the structure of the adsorption plate 6 is improved. There are multiple adsorption plates 6, and several through holes are opened at intervals on the outer surface thereof, and the through holes on each layer of the adsorption plate 6 are staggered with each other, that is, the adsorption plate 6 is multi-layered, stacked and the through holes are staggered with each other, which can effectively reduce the possibility of dust falling back into the filter element body 2 and further improve the service life of the filter element body 2. There are three adsorption plates 6, which can reduce the cost of use while achieving the desired purpose.

[0028] The top of the mounting plate 4 in Example 1 and Example 2 is fixedly connected with a reset component 8 near its corner, and the reset component 8 includes a bottom sleeve 82, and the inner surface of the bottom sleeve 82 is slidably connected with a top pressure foot 81 used in conjunction with it. A light spring is also arranged in the bottom sleeve 82. The bottom sleeve 82 and the top pressure foot 81 are made of ceramic materials, which can increase the movement amplitude of the piezoelectric ceramic plate assembly 3, thereby ensuring the stability of its power generation and enabling it to work fully and effectively. The top of the mounting plate 4 is located at the position of each piezoelectric ceramic module, and a protrusion 9 used in conjunction with it is also installed to enable the piezoelectric ceramic module in the piezoelectric ceramic plate assembly 3 to fully accept the deformation force so that it can meet the working requirements. Please refer to Figure 3 A pressing frame 10 is also provided between the filter housing 1 and the adsorption plate 6. The pressing frame 10 is embedded at the top of the inner surface of the filter housing 1, and the adsorption plate 6 is embedded at the inner surface of the pressing frame 10 near the top thereof, so that there is sufficient clearance between the adsorption plate 6 and the filter body 2 in the filter housing 1 to prevent the accumulated dust from falling back after contacting the filter body 2 and to prevent the filter body 2 from being unstable. The front and back of the filter housing 1 are fixedly connected with the limiting protrusion 11 to facilitate the installation of the filter.
