[0040] Working principle:

[0041] The device filtering steps: see Figure 3, the outside air enters the rain cap 11 through the plurality of air inlet holes 13, then enters the installation screw barrel 15, the matching installation barrel 2 and passes through the fixed link 75 to enter the transparent cover 76, and then the gas in the transparent cover 76 passes through the plurality of elliptical through holes 751, is filtered and purified by the second filter element 74 and the first filter element 72 in multiple layers, and is discharged through the exhaust pipe 6, so as to provide pure air to the engine, and thus facilitate the later engine operation;

[0042] The quick-change installation assembly 8 cooperates with the filter element assembly 7: see Figure 1 and Figure 3 , which is a schematic diagram of the filter element assembly 7 being installed in the filter housing 3 through the quick-change installation assembly 8. When the filter element needs to be replaced, the filter element assembly 7 needs to be pulled out from the filter housing 3. At this time, by moving the adjustment pressure plate outward, the adjustment pressure plate is driven to be hinged along the U-shaped seat 83 under the hinge operation. At the same time, under the cooperation setting of the torsion spring 82, the adjustment pressure plate is separated from the fixed plate 81, driving the L-shaped matching plate 84 to move, and at the same time driving the clamping plate 85 to separate from the mounting outer ring 101, and then driving the matching pressure ring to separate from the concave ring pressure groove 102. In this way, the filter element assembly 7 can be taken out of the filter housing 3 by pulling the filter element assembly 7 outward. When the filter element needs to be replaced, it is only necessary to remove the first filter element part 72 and the second filter element part 74 from the fixed sleeve 73, and then put on a new filter element part. The filter element assembly 7 is installed in the filter housing 3 by placing the filter element assembly 7 into the filter housing 3, and then the installation inner ring 10 is sleeved on the transparent cover body 76 and is located in the gap between the filter housing 3 and the transparent cover body 76. At this time, the installation outer ring 101 contacts the filter housing 3, and then the clamping plate 85 contacts the installation outer ring 101. By pressing down the adjustment clamping plate, the adjustment clamping plate is driven to be hinged along the U-shaped seat 83. Under the action of the torsion spring 82, the clamping plate 85 is driven to press the installation outer ring 101, and then the matching clamping ring is pressed into the concave ring pressure groove 102, so that the adjustment clamping plate is pressed and pressed onto the fixing plate 81. In this way, it is convenient to fix the filter element assembly 7 in the filter housing 3, which is not only simple to operate, but also convenient to replace the filter element at a later time, which is conducive to increasing the practicality and service life of the device.

[0043] Air intake protection kit 1: see Figure 3Through the setting of the rainproof cap 11, the mounting ring 14 is located inside the rainproof cap 11, and an air inlet hole 13 is opened on the mounting ring 14, and the air inlet hole 13 is also located inside the rainproof cap 11. The rainproof cap 11 can be used to block rain from the air inlet position to prevent rainwater from entering the filter housing 3 from the air inlet hole 13 and affecting its filtering effect. At the same time, since a matching threaded ring 12 is fixedly provided in the middle of the mounting ring 14, the matching threaded ring 12 is threadedly sleeved on the mounting screw barrel 15, which is convenient for installing and disassembling the air inlet protection matching component 1, which is beneficial to increasing the practicality of the device.
