The flushing device 100 mainly comprises a friction table 1, a spraying assembly 2, a driving mechanism 3, a transmission assembly 4 and a containing cavity 5. Wherein the friction table 1 is exposed from the docking station 10, the friction table 1 being configured for carrying a cleaning assembly 201 to be cleaned and being capable of rubbing against the cleaning assembly 201. The spraying assembly 2 is provided at a side of the rubbing table 1 and is configured to suck the cleaning liquid from the container 5 and spray the sucked cleaning liquid to the cleaning assembly 201 which performs a rubbing motion with the rubbing table 1. The transmission component 4 is in transmission connection with the power output end of the driving mechanism 3, and the injection component 2 is in transmission connection with the power output end of the transmission component 4. The chamber 5 is used for storing a cleaning liquid, such as water, or a fluid with a cleaning agent, or even a disinfectant such as 84 disinfectant, ethanol water solution, etc.

Wherein, the power provided by the driving mechanism 3 is transmitted to the spraying component 2 through the transmission component 4, and the spraying component 2 is driven to perform actions of sucking the cleaning liquid and spraying the cleaning liquid. Preferably, the actions of sucking the cleaning liquid and spraying the cleaning liquid are periodically repeated.

The washing apparatus 100 provided in the above embodiment has the following flow when washing the cleaning assembly 201 mounted on the cleaning robot 200: first controlling the cleaning robot 100 to park on the docking station 10 while bringing the cleaning assembly 201 into opposition to and into contact with the friction station 1; then the friction table 1 and the cleaning assembly 201 are controlled to move mutually to generate friction, and meanwhile the spraying assembly 2 is controlled to absorb cleaning liquid and spray the cleaning liquid, and the cleaning liquid is sprayed onto the cleaning assembly 201 to be washed under high pressure. The cleaning process does not need to detach the cleaning assembly 201 from the cleaning robot 200, so that the cleaning efficiency is improved, and dirt or viscous substances deposited on the cleaning assembly 201 can be effectively washed and removed based on the friction action of the friction table 1 and the injection action of the injection assembly 2, so that a good cleaning effect is achieved.

The rubbing board 1 may have a structure with scraping protrusions on its upper surface, or may have a structure similar to a washboard. The mutual friction between the friction table 1 and the cleaning assembly 201 may be rotational friction, rolling friction or even reciprocating friction, and the specific friction movement pattern depends on the structure of the cleaning assembly 201 and its movement pattern relative to the cleaning robot 200 and the movement pattern of the friction table 1. For example: when the cleaning assembly 201 selects a rotary floor-scrubbing plate mounted at the bottom of the cleaning robot 200, the friction table 1 and the cleaning assembly 201 (rotary floor-scrubbing plate) can adopt mutual rotation friction; when the cleaning assembly 201 adopts the floor wiping roller arranged at the bottom of the cleaning robot 200, the friction table 1 and the cleaning assembly 201 (floor wiping roller) can adopt the mutual rolling friction; when the cleaning assembly 201 is a mop floor or a vibrating mop floor mounted on the bottom of the cleaning robot 200, the friction table 1 and the cleaning assembly 201 (mop floor or vibrating mop floor) may use friction with respect to each other in a reciprocating motion. When the cleaning assembly 201 is cleaned, one of the friction table 1 and the cleaning assembly 201 is set to move; when both are arranged to move simultaneously, the directions of movement of both are preferably opposite directions.
