As shown in FIG. 1 to FIG. 3, the working process of the cyclone separation device provided by the present invention is as follows:

A fan (not shown) is disposed at the air outlet 102 of the dust bucket 100. Under the action of the fan, the gas-liquid mixed airflow enters the dust bucket 100 through the first air inlet 101, and the first air inlet 101 includes a tangential direction. The inlet air duct generates a cyclone separation in the dust bucket 100 after the airflow enters. The liquid in the mixed gas stream is separated by the blockage of the mesh filter 300 by the centrifugal force, and is collected to the bottom of the dust bucket 100, and a part of the water vapor passes through the mesh filter 300 and the secondary filter in turn. The wind tunnel enters the multi-cone filter 200. As shown in FIG. 3, the water vapor enters the high efficiency cone 250 from the high efficiency air inlet 220 under the action of the air flow of the multi-cone filter 200, and the remaining water vapor is separated into the inner dust barrel 400 by the high efficiency cyclone of the high efficiency cone 250. The air enters the air outlet 102 of the dust bucket 100 from the high efficiency air outlet 240 to enter the fan. During the working process, as the amount of accumulated water increases, the level of the liquid remaining inside the dust bucket 100 rises continuously, generating buoyancy to the float 110, and when the float 110 rises to the secondary air inlet by the buoyancy of the accumulated liquid The top end of the second air inlet is blocked, so that the high efficiency cone 250 stops working, the airflow in the dust bucket 100 disappears, the whole machine can not continue to absorb water, effectively preventing the liquid from overflowing from the dust bucket 100, and preventing the water from being sucked in. The motor room ensures safe use. Subsequently, the user can open the bottom cover (not shown) disposed at the bottom of the dust bucket 100 in the stopped state, and manually discharge the liquid inside the dust bucket 100 and the inner dust bucket 400, and then clean the interior thereof. Wait for the next use.
