Description

technical field [0001] The invention belongs to the technical field of cleaning equipment, in particular to a cleaning head for floor cleaning equipment. Background technique [0002] In daily life, vacuum cleaners are usually used to absorb dust and other particles on the ground to be cleaned, especially for cleaning rough ground, such as cleaning indoor carpets, wooden floors, etc., and for cleaning smooth ground, such as floor tiles, ceramic tiles, etc., In general, a clean mop is used to scrub the smooth ground with a wet mop to remove stains on its surface. However, such a cleaning method inevitably requires the user to replace the cleaning tool many times to realize the cleaning operation of the surface to be cleaned, which is relatively cumbersome to operate. [0003] The Chinese invention patent application with the publication number CN108852185A discloses a "water tank and automatic cleaning device". The gear adjustment key selectively seals the first adjustment ...

Problems solved by technology

If the second regulating port is set on the top wall of the second water chamber, and the first regulating port is opened on the top wall of the first water chamber, then when the first regulating port is closed and the second regulating port is opened, due to the two The water chambers are interconnected and the water level in the first water chamber is higher than the water level in the second water chamber, then the water in the second water chamber will emerge from the second adjustment port, wet the outside of the box, and even enter the interior of the sweeping robot , causing damage to the motor; in addition, if there is a ventilation hole on the water tank, and the ventilation hole is in an open state, the outside air will only enter the water tank from the ventilation hole, and the opened adjustment port and the liquid outlet will In the case of water outflow, the above-mentioned water in the water tank will still leak from the opened adjustment port
