The cover 50 is positioned above the filter 40, the filter 40 and the cover 50 may be integrally constructed, the filter 40 is inserted into or taken out from the cavity with the cover 50, or the filter 40 and the cover 50 may be separated, the filter 40 is vertically compressed in the inner cavity by the cover 50, and the air flow outlet duct 125 is positioned at the rear side of the filter 40 to be connected to the upper case 211.
As shown in fig. 2,3 and 7, the upper case 211 has an air flow inlet pipe 2112, and when the rear end portion 20 is inserted into the front end portion 10, the air flow inlet pipe 2112 is abutted with the air flow outlet pipe 125 so that the air flow outlet pipe 125 communicates with the air flow generator. In this embodiment, the air inlet pipe 2112 is the inlet of the air flow generator, and when the rear end portion 20 is plugged with the front end portion 10, the air flow generator directly aligns with the cavity 123 to form a strong negative pressure.
The rear end face 1251 of the surface of the air outlet pipe 125 is a slope inclined toward the rear end in the plugging direction of the rear end portion 20 (vertically downward in this embodiment), the front end face 2113 of the air inlet pipe 2112 is the same as the inclination direction of the slope, the rear end face 1251 or the front end face 2113 is provided with an annular seal member 50, and as the rear end portion 20 is plugged vertically with the cylinder 111, the rear end face 1251 and the front end face gradually come into butt-close in the slope manner, the seal member 50 is pressed very reliably between the rear end face 1251 and the front end face 2113, so that the gap between the air inlet pipe 2112 and the air outlet pipe 125 leaks air in the manner by the seal member 50.
