Liquid-spraying device and glass-cleaning robot with liquid-spraying device

Abstract

The invention provides a liquid-spraying device and a glass-cleaning robot with the spraying device. The liquid-spraying device comprises a solution bottle (1) and an automatic pushing mechanism (2); the automatic pushing mechanism (2) comprises a drive motor (21); an output shaft of the drive motor (21) is connected with a rotation part (22); a swinging rod (25) is hinged at one side of the rotation part (22); the other end of the swinging rod (25) is hinged with one end of a pushing rod (26); a free end of the pushing rod (26) and a pressing end of the solution bottle (1) are arranged correspondingly, and a hinge point of the swinging rod (25) on the rotation part (22) and a gyration centre of the rotation part (22) are arranged at an interval. The liquid-spraying device and the glass-cleaning robot, provided by the invention, have the advantages of simple structure, convenience in use, good controllability and high spraying efficiency, and can avoid pollution.

Description

technical field [0001] The invention relates to a liquid spraying device and a glass-wiping robot equipped with the liquid spraying device, belonging to the technical field of robot manufacturing. Background technique [0002] Existing glass-wiping robots all use a water storage tank integrated in the main body of the machine to store clean water, detergent, and a mixture of clean water and detergent, and then use an air pressure conversion mechanism to make the liquid in the water storage tank spray out. When the water storage tank is used to store the cleaning liquid, there is the defect that it is inconvenient to replace the cleaning liquid. For example, when the cleaning liquid A is used at the beginning and the cleaning liquid B needs to be replaced later, due to the remaining cleaning liquid A in the water storage tank, the difference between the cleaning liquid and the cleaning liquid B will be caused. mix. And when replacing the cleaning night, special care must be ...

Problems solved by technology

When the water storage tank is used to store the cleaning liquid, there is the defect that it is inconvenient to replace the cleaning liquid. For example, when the cleaning liquid A is used at the beginning and the cleaning liquid B needs to be replaced later, due to the remaining cleaning liquid A in the water storage tank, the difference between the cleaning liquid and the cleaning liquid B will be caused. mix

And when replacing the cleaning night, special care must be taken when pouring the cleaning solution into the water storage tank. If the cleaning solution overflows or leaks during the dumping process, it will easily cause pollution to the robot, and in serious cases, it may cause a short circuit on the circuit board, causing the robot to unable to work properly

In addition, the air pressure conversion structure used by existing glass-wiping robots makes the process of spraying cleaning fluid very complicated

It is necessary to set multiple air intake or exhaust holes. If the air intake or exhaust holes are blocked, the cleaning liquid in the water storage tank will not be able to be ejected normally.
