the embodiment is similar to the embodiment, and the only difference is that in the embodiment, in addition to the structure of the embodiment two, structures such as an L-shaped linkage rod 24 and a special-shaped piston tube 26 are additionally provided.
When the ratio of the air intake amount of the fresh air inlet 10311 to the air intake amount of the rich air inlet 10312 is adjusted as described in the second embodiment, the intermediate rod 19 moves, at this time, the intermediate rod 19 drives the first piston plate 25 to move along with the movement of the intermediate rod 19 through the L-shaped linkage rod 24, the first piston plate 25 is slidably disposed in the special-shaped piston tube 26, under the action of the piston cavity 28, the second piston plate 27 moves along with the movement of the first piston plate 25, the second piston plate 27 drives the carrying cross rod 30 through the connecting rod 29, so that the screen cleaning brush 31 on the carrying cross rod 30 can move up and down relative to the screen 16, and further the screen 16 is cleaned, thereby avoiding the local blockage of the screen 16 after the dust is attached, further causing the problem that the difference between the preset air intake amount in the second embodiment and the preset air intake amount actually caused by the fact that the screen 16 cannot ventilate smoothly, and ensuring the effectiveness of the device, and the operation does not need extra manual treatment, and the use is more convenient.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
