Description

A mopping adjustment mechanism

technical field

The utility model belongs to the field of automatic cleaning, in particular to a mopping adjustment mechanism for a robot vacuum cleaner.

Background technique

Looking back on the development of cleaning robot technology at home and abroad for more than ten years, the development trend has changed from the initial realization of cleaning functions to the pursuit of higher intelligence. At present, the structural innovation is mainly aimed at the appearance and size of the robot. The robots with multi-floor cleaning capabilities designed by major manufacturers must meet the premise that the ground must be very flat. Especially for mopping robots, if the ground is slightly uneven, there will be residual water marks.

At present, in the field of cleaning robots, mopping technology is still a difficult research point, and there is no good solution at present. An existing mopping technology can be described as: first use a pump to spray the cleaning liquid in front of the cleaning robot, and then the cleaning brush will Brush the ground with cleaning fluid, and finally use the pump to absorb the cleaning fluid on the brushed ground. The main problem with this technology is that when the ground is not very smooth, there will be more cleaning fluid on the ground.

In the prior art, the invention patent with the publication number CN103393384A discloses a mopping module and a cleaning robot, including an installation platform, nozzles installed on the installation platform, cleaning rollers, a water supply system and a power system, the water supply system It is connected with the nozzle for water supply of the nozzle, and the power system is connected with the cleaning roller for the rotation driving of the cleaning roller, wherein the mopping module also includes a sponge roller and a sewage roller installed on the installation platform The recovery system, the sponge roller is connected with the power system for the rotation drive of the sponge roller, the sewage recovery system is connected with the sponge roller for the sewage recovery of the sponge roller; the nozzle is located at the front end of the installation platform, the The cleaning roller and the sponge roller are respectively located at the bottom of the installation platform, and the cleaning roller is located in front of the sponge roller.

However, the above solution has the problem of poor adaptability to the ground. Since the position of the sponge brush is fixed, when the ground is uneven, it cannot be ensured that the sponge brush always adheres to the ground, resulting in residual sewage.

In view of the current status of mopping technology, there is an urgent need for a mopping mechanism with ground adaptability to solve the problem that water stains cannot be cleaned.
