Description

Cleaning module for cleaning machine and cleaning machine

technical field

The utility model belongs to the field of household washing and cleaning, and in particular relates to a cleaning mold for a cleaning machine and a cleaning machine.

Background technique

The current cleaning machine includes a floor washing machine and a sweeping machine. The cleaning machine mainly uses a roller brush to sweep debris into the dirt suction cavity, and then uses a fan to suck the ground debris into its internal dirt collection cavity, thereby completing the cleaning process. The cleaning function of the ground.

In order to improve the cleaning ability of stubborn stains on the ground, the roller brush needs to be wetted before the roller brush is cleaned. Most of the existing equipment realizes this process by spraying water on the roller brush, such as the Chinese utility model patent "Cleaning Equipment 》, its patent number is the cleaning equipment disclosed in ZL201910808285.4. The water sprayed from the water outlet is mixed with the gas sprayed from the gas outlet, and then sprayed out through the main injection pipeline.

Although such a water outlet form can complete the wetting action, such a water outlet design form makes the water outlet part too concentrated, resulting in uneven humidity in various parts of the entire roller brush.

Therefore, need further improvement to existing rolling brush.
