The suction assembly 400 described herein is used with water suction devices 100, particularly large floor washers, where air suction is required to draw water into a waste tank.
Referring to fig. 1, the present application provides a suction assembly 400, which includes a first intake vent 410, a baffle 420 and a driving device 430, wherein the first intake vent 410 is used for intake air, and the baffle 420 is used for limiting intake air of the first intake vent 410; the driving device 430 is used for drawing air, the driving device 430 can draw air from the first air inlet 410 when in operation, and can drive the shielding member 420 to move from the first position to the second position when the driving device 430 is in operation; when the shielding member 420 is at the first position, the shielding member 420 can shield the first air inlet 410 to limit the air inlet of the first air inlet 410, and when the shielding member 420 moves away from the first position under the driving of the driving device 430, the first air inlet 410 can inlet air under the action of the driving device 430.
Specifically, the driving device 430 has an adsorption force during operation, and the adsorption force generated by the driving device 430 can adsorb the shielding member 420, which is represented by:
when the driving device 430 works, the shielding piece 420 can be adsorbed by the driving device 430, the shielding piece 420 is adsorbed from the first position to the second position, the driving device 430 draws air, and water can be adsorbed;
when the driving device 430 stops working, the driving device 430 does not exhaust air any more, the driving device 430 loses the adsorption force on the shielding piece 420, the self-gravity of the shielding piece 420 enables the shielding piece 420 to fall from the second position to the first position, and then the first air inlet 410 is blocked so that the first air inlet 410 cannot intake air. Thus, the movement of the shielding member 420 is controlled by the driving device 430, and air can be effectively prevented from entering the first air inlet 410 when the driving device 430 stops working.
In an embodiment, when the shielding member 420 is in the first position, the shielding member 420 abuts against the first air inlet 410 to limit the air inlet of the first air inlet 410. In order to limit the air inlet of the first air inlet 410, the shielding member 420 may extend into the first air inlet 410 or shield the first air inlet 410 outside the first air inlet 410, and since the shielding member 420 can move and can block the first air inlet 410 when moving to the first position, the shielding member 420 is abutted to the first air inlet 410, so that a part of the structure of the shielding member 420 can block the first air inlet 410, and thus, the limiting effect of the shielding member 420 on the first air inlet 410 is better.

In certain more specific embodiments, as shown in fig. 8, the baffles 4211 are triangular plates with three support posts 4221 disposed at three corners of the triangular plates. More specifically, the triangle plate is an equilateral triangle plate, the support column 4221 is disposed at three corners of the equilateral triangle, so that the baffle 4211 is disposed in a triangle shape, so that the baffle 4211 has enough space for the air flow to pass through when being adsorbed by the driving device 430, and the support column 4221 is disposed at three corners to ensure that the three columns are not adsorbed by the driving device 430, which results in the driving device 430 being damaged.
