Description

Sewage tank, cleaning equipment and cleaning system Technical Field The disclosure relates to the technical field of cleaning, in particular to a sewage tank, cleaning equipment and a cleaning system. Background The cleaning equipment is one of intelligent household appliances, and can automatically complete the cleaning work of the surface to be cleaned in the walking process. For example, the cleaning device may be a sweeping, floor scrubbing robot. The floor cleaning robot is provided with a cleaning piece and a sewage tank, and the cleaning equipment can spray water onto the cleaning piece in the walking process, clean the floor to be cleaned through the cleaning piece and then suck sewage on the floor to be cleaned into the sewage tank for temporary storage. When the robot works, the motor enables negative pressure to be generated inside the sewage tank, so that air is sucked, sewage and dirt are sucked into the sewage tank along with the air, the water-gas separation effect of the sewage tank of the existing floor cleaning robot is poor, the condition that sewage is sucked into the motor along with air possibly exists, and the performance and the service life of the motor are affected. Disclosure of utility model The embodiment of the disclosure provides a sewage tank, cleaning equipment and cleaning system, which are used for improving the water-gas separation effect of the sewage tank, so that water and gas are fully separated, and the maintenance-free degree is improved. In a first aspect, embodiments of the present disclosure provide a sewer tank for use in a cleaning device, the sewer tank comprising: The shell is internally provided with a dirt storage cavity, the shell is provided with a dirt inlet and a dirt outlet, the dirt inlet and the dirt outlet are respectively communicated with the dirt storage cavity, the dirt inlet is used for sucking a water-containing airflow, and the air outlet is used for discharging the air of the water-containing airflow after water-gas separation; The water retaining component is arranged in the sewage storage cavity and is matched with the sewage storage cavity to guide a flow path of the water-containing air flow, and liquid in the water-containing air flow sinks to the bottom of the sewage storage cavity on the flow path to realize water-gas separation of the water-containing air flow; The guide structure is arranged in the sewage storage cavity and is provided with a slope surface, and the slope surface is used for guiding the water-containing air flow entering the sewage storage cavity from the sewage inlet and preventing the water-containing air from flowing to the bottom of the sewage storage cavity. The utility model provides a sewage case through design inlet on the casing for inhale the mixed fluid that contains water and gas, be equipped with the dirt storage chamber in the casing, be used for holding and handling the sewage of inhaling in the cleaning equipment, design gas outlet for the exhaust gas after the separation. And a water blocking part positioned in the sewage storage cavity is designed to guide the flow path of the water-containing air flow together with the inner wall of the sewage storage cavity. The path intercepts the water vapor in the separation process by limiting the flow of the water-containing air flow, so that the liquid part is settled to the bottom of the dirt storage cavity, the gas part continues to flow, and finally the gas is discharged through the gas outlet, thereby realizing the gas-liquid separation of the water-containing air flow. Meanwhile, a guide structure is designed at a position close to the sewage inlet, the slope of the guide structure is used for guiding the entering water-containing air flow, the water-containing air flow is prevented from flowing to the bottom of the sewage storage cavity, the surge of the air flow at the beginning stage to the liquid level of the sewage tank is eliminated, the air flow is prevented from blowing to the liquid surface at the bottom of the sewage storage cavity, the liquid level is prevented from vibrating, and therefore the water-air separation effect is improved. Through the design, the sewage tank can remarkably improve the water-gas separation effect, ensures that the gas sucked into the motor does not contain liquid, reduces the potential influence of liquid on the motor performance and service life, and improves the maintenance-free characteristic of equipment.
