By setting the paint mesh layer 21, the carbon cloth layer 22, and the primary mesh layer 23, the device can further improve the filtering and purification effect of the filter element 2. The base 3 includes a mounting plate 31, and air holes 32 are arranged at intervals in the mounting plate 31, and mounting holes 33 are arranged at intervals at the edge of the mounting plate 31. By setting the mounting plate 31, the air holes 32, and the mounting holes 33, the base 3 of the device can further facilitate the air outlet and installation in the air duct. The filter element 2 also includes a lower mounting portion 24 arranged at its lower part, and a lower mounting groove 34 adapted to the lower mounting portion 24 is arranged at the upper end of the mounting plate 31, and the lower mounting portion 24 and the lower mounting groove 34 are detachably connected by threads. By providing the lower mounting portion 24 and the lower mounting groove 34 , the base 3 of the device can further facilitate the installation of the filter element 2 .

[0024] The specific working principle of this utility model:

[0025] When the device is used, the base 3 is fixedly installed at the air inlet of the air duct through the mounting hole 33 and the bolts, with the end where the base 3 is located facing outward. When the air in the air duct starts to be drawn, the external air will first be filtered by the layers of the filter element 2 and then enter the air duct from the mounting plate 31; when it is necessary to remove the upper cover 1 to clean the inside and outside of the filter element 2, tighten the upper cover 1 so that the upper mounting groove 11 and the threaded portion of the upper mounting portion 25 are tightly engaged, then rotate the upper cover 1 to unscrew the upper cover 1 and clean the inside and outside of the filter element 2. After cleaning, the upper cover 1 can be installed back in the original way; when it is necessary to replace the filter element 2, press the upper cover 1 so that the tooth pattern 4 between the upper cover 1 and the upper mounting portion 25 is engaged and clamped, and at the same time, the upper cover 1 is rotated again, thereby driving the filter element 2 to rotate, unscrewing the thread between the lower mounting portion 24 and the lower mounting groove 34, and the filter element 2 is removed, and then the new filter element 2 is installed back on the base 3 in the original way, completing the whole replacement process. In the above process, the utility model cooperates with the upper cover 1, the filter element 2, the base 3, the tooth pattern 4 and other structures, so that the device can operate the upper cover 1 to press the tooth pattern 4 to screw out the filter element 2 or pull the upper cover 1 to cooperate with the threaded connection of the upper mounting portion 25 and the upper mounting groove 11 to screw out the upper cover 1, thereby facilitating the installation, disassembly or replacement of the filter element 2 and improving efficiency.
