Problems solved by technology
Another way is to increase the distance between the air outlet and the highest water surface of the sewage tank. This method has a poor sealing effect, and it is inevitable that water vapor will enter the suction motor. The biggest disadvantage is that a lot of space for the sewage tank is sacrificed.
At present, neither of these two methods can fundamentally solve the problem of sewage entering the sewage tank, and the disadvantages are obvious
[0004] In order to solve the problem that the sewage of the property cleaning robot may enter the suction motor, it is necessary to provide a vacuum system for the sewage tank of the cleaning robot

The invention discloses a vacuum-pumping system for a sewage tank of a cleaning robot and the cleaning robot. The vacuum-pumping system comprises the sewage tank, wherein an air duct is arranged on the upper portion of the sewage tank, and a first air opening and a second air opening are formed in the two sides of the air duct respectively; a bracket which is arranged in the sewage tank; a blocking assembly which is arranged on the support in a sliding mode, wherein the blocking assembly can seal the first air opening; and an air outlet pipe, wherein one end of the air outlet pipe is connected with the second air opening, and the other end of the air outlet pipe extends out of the sewage tank and can be connected with a fan. The cleaning robot comprises the cleaning robot sewage tank vacuumizing system. The support is arranged in the sewage tank, the blocking assembly is slidably arranged on the support, when the water level rises, the blocking assembly ascends along the support under the action of buoyancy until the blocking assembly blocks the first air opening and the air channel under the action of buoyancy and suction force of wind, and at the moment, the draught fan does not suck air in the sewage tank any more.
Description
technical field [0001] The invention relates to the field of cleaning equipment, in particular to a cleaning robot sewage tank vacuuming system and a cleaning robot. Background technique [0002] In recent years, with the continuous increase of labor costs and the continuous progress of intelligent property services, property cleaning robots have increasingly entered application scenarios such as residential quarters, office buildings, and hospitals. [0003] In the process of use, most of the property cleaning robots with a high level of intelligence adopt the operation mode of automatically washing the floor, sucking sewage into the sewage tank, and automatically discharging sewage. During the process of sucking the sewage into the sewage tank, it often happens that the sewage enters the suction motor, thereby damaging the suction motor. In response to this problem, the industry often adopts two methods to solve it. One is to set a floating ball at the front end of the a...
