Description

Gas channel switching device of recovery processing device and recovery processing device

Technical Field

The present disclosure relates to a gas passage switching device of a recovery processing device and a recovery processing device.

Background

The working principle of the cleaning machine is that cleaning liquid such as water and the like is sprayed on the surface to be cleaned, the movement speed of the molecules on the dirt surface is increased, and stubborn dirt, oil stain and the like are eliminated by damaging the binding force between the cleaning liquid and the molecules; and the dirt generated by cleaning the surface is absorbed to the recovery processing device through the ground brush suction port, so that the surface is cleaned.

At present, the sewage recovery of the sewage tank is carried out manually. That is, when the amount of dirt stored in the recycling device reaches a certain threshold, the recycling device needs to be manually removed from the cleaning machine and the surface cleaning operation can be resumed after the dirt is dumped.

If the automatic mode is adopted to clear up the dirt in the sewage tank, a separate suction source needs to be arranged on the base station, and when the cleaning machine stops at the base station, the dirt in the sewage tank is sucked to the base station through the suction source of the base station, so that the cost of the base station is undoubtedly increased.
