Description

Technical Field

[0001] The utility model relates to the field of water injection structures, in particular to a water injection structure of a base station of a sweeping robot. Background Art

[0002] A sweeping robot is a household appliance that automatically sweeps the floor. It usually has various sensors and control systems, can sense the environment and autonomously plan a cleaning path, and sweeps using cleaning tools such as a broom or a vacuum cleaner. The water injection structure of the sweeping robot base station usually includes a container for storing cleaning liquid or water. This container is usually connected to the cleaning box of the sweeping robot through a water injection pipe. The cleaning liquid can help to effectively remove stains on the floor and increase the cleaning effect. In the existing water injection structure, a tap water pipe is usually used to add water to the water tank during the water injection process. Since there are tiny impurity particles remaining in the tap water that mix with the cleaning liquid, long-term use of the cleaning liquid mixed with impurities can easily cause the water injection port inside the sweeping robot base station and the inside of the sweeping robot to be blocked, affecting the normal operation of the device. Therefore, we propose a water injection structure for the sweeping robot base station to solve the above-mentioned problems. Utility Model Content

[0027] When working, first manually grasp the rotating buckle 204 and connect the threaded rubber ring 205 to rotate clockwise to pull it out from the inside of the sleeve rod 203. The rotating buckle 204 and the threaded rubber ring 205 are used to seal the sleeve rod 203 to prevent leakage of the cleaning liquid and prevent impurities from entering the base station 1 after adding water flow, thereby ensuring the cleanliness and sanitation of the base station 1. After the sleeve rod 203 is opened, the faucet water pipe is docked and fixed to the sleeve rod 203.

The water flow injected into the water storage tank 303 is filtered out by the filter to filter out impurities and particulate matter in the water, thereby ensuring that the water flow injected into the base station 1 is purer and cleaner. At the same time, the filter can prevent impurities and particulate matter in the water storage tank 303 from clogging the nozzle or pipe, thereby ensuring smooth water flow. The clamping block 212 is combined with the telescopic spring 210 to slide along the telescopic groove to open the base station 1, thereby realizing the opening and closing of the base station 1, ensuring the cleanliness of the inside of the base station 1, preventing impurities from entering the inside of the base station 1, and ensuring the normal use of the base station 1. The limiting top cover 301 is connected to the water tank 303 through the limiting block 304, and the water tank 303 is sealed to avoid shaking during use, which may cause overflow of the internal cleaning liquid. The dust collection rack 405 is used to dock the robot to collect internal impurities into the movable frame 401, effectively collecting impurities inside the robot, avoiding the deposition and overflow of magazines, and ensuring the normal operation of the robot.
