Water tank of cleaning robot, cleaning robot and cleaning system

Abstract

The invention discloses a water tank of a cleaning robot, the cleaning robot and a cleaning system. The water tank of the cleaning robot comprises a tank body, wherein the tank body is provided with a water storage cavity, a water inlet and a water outlet, and the water inlet and the water outlet communicate with the water storage cavity; a water passing channel which is at least provided with a sealing section extending in the vertical direction, wherein the sealing section is provided with a water outlet end communicated with the water inlet and a water inlet end located below the water outlet end; a valve body which is communicated with the water inlet end of the sealing section, wherein the valve body is in an open state under the action of water in the water source pipeline, and the valve body is in a closed state under the action of the water in the water source pipeline without the action of the water in the water source pipeline and the action of the water in the sealing section. When the water tank is detached from the machine body, residual liquid in the water inlet can be prevented from dripping to the surrounding ground.

Description

technical field [0001] The invention relates to the technical field of cleaning robots, in particular to a water tank of a cleaning robot, a cleaning robot and a cleaning system. Background technique [0002] In recent years, with the development of social economy and the improvement of family living standards, household cleaning has gradually entered the era of intelligence and mechanization. The workload of cleaning can relieve people's fatigue in the process of household cleaning. [0003] A cleaning robot usually includes a machine body and a water tank detachably connected to the machine body. The water tank is provided with a water storage chamber for storing liquid to be applied to the floor surface. The water storage chamber is usually provided with a water inlet and a water outlet. When adding water, first close the water outlet, and then communicate with the water inlet to add water to the water storage chamber through the water source waterway. The water inlet ca...

AI Technical Summary

Problems solved by technology

[0004] The defects in the above-mentioned prior art are: when the water inlet is set up and down, the upper end of the water inlet communicates with the water storage chamber, and the lower end of the water inlet is used to communicate with the water source waterway, adding water to the water storage chamber will make the water intake The mouth is full of liquid, so when the water tank is removed from the machine body, the liquid remaining in the water inlet will drip to the surrounding ground, so it is urgently needed to improve
