Description

Self-cleaning drainage device, cleaning equipment and cleaning system Technical Field The utility model relates to the technical field of cleaning equipment, in particular to a self-cleaning drainage device, cleaning equipment and a cleaning system. Background Existing cleaning devices are typically equipped with a sump for recovering the effluent generated during cleaning operations of wet cleaning elements (e.g., wipes, rollers, etc.). However, after long-term use, the inner wall of the sewage tank is easy to accumulate dirt and remain, and periodic cleaning is required. For this purpose, the prior art generally provides a self-cleaning mechanism inside the tank. The automatic cleaning of the inner wall of the sewage tank is realized by spraying clean water. Currently, self-cleaning mechanisms for sewage tanks typically require a separate water supply system (e.g., an additional configuration of water pumps, piping, etc.) to perform the cleaning function. However, the introduction of such a separate water supply system not only increases the fresh water supply cost of the self-cleaning mechanism, but also makes the structure of the entire cleaning apparatus more complicated and results in an increase in manufacturing costs. Disclosure of utility model In view of the above problems in the prior art, the present utility model provides a self-cleaning drainage device, a cleaning apparatus and a cleaning system, which can reduce the clean water supply cost of a self-cleaning mechanism in a sewage tank. To achieve the above and other related objects, a first aspect of the present utility model provides a self-cleaning drainage device, comprising a sewage tank, a clean water tank and a suction device, wherein the sewage tank comprises a clean water inlet and a self-cleaning mechanism, the self-cleaning mechanism introduces clean water from the clean water inlet to flush the inner wall of the sewage tank, the clean water tank is used for containing the clean water, an overflow port is arranged on the clean water tank, the suction device is used for sucking the clean water into the clean water tank, and the clean water inlet is communicated with the overflow port so that the clean water flowing out from the overflow port can be drained to the self-cleaning mechanism under the action of gravity. The beneficial effect of the arrangement is that as the clean water inlet is communicated with the overflow port of the clean water tank, when the clean water tank is filled with water, redundant clean water can be discharged through the overflow port after the water level reaches the preset height. The part of clean water can be naturally drained to the self-cleaning mechanism under the action of gravity and is used for flushing the inner wall of the sewage tank. Because the overflow water generated in the water injection process of the clean water tank is used as a clean water supply source of the self-cleaning mechanism, the clean water supply of the self-cleaning mechanism and the clean water supply of the clean water tank can share the same suction device, and an independent clean water supply system is not required to be additionally arranged for the self-cleaning mechanism, so that the clean water supply cost of the self-cleaning mechanism can be effectively reduced, the integral structure of the self-cleaning drainage device can be simplified, and the integral manufacturing cost can be reduced. In one embodiment of the utility model, the fresh water tank includes a mounting cavity in which the dirty water tank is nested. The sewage tank is embedded in the installation concave cavity, so that the integrated arrangement of the sewage tank and the clean water tank can be realized, the occupied area of the clean water tank and the sewage tank in the horizontal direction of the cleaning equipment or the cleaning base station is reduced, the space layout of the cleaning equipment or the cleaning base station can be optimized, and the compactness of the structure is improved. Simultaneously, sewage case and clean water tank integrated setting can also make things convenient for the dismouting operation of sewage case and clean water tank on clean equipment or clean basic station, improves the convenience of use. In one embodiment of the utility model, at least part of the clean water cavity in the clean water tank is arranged above the sewage tank, and the overflow port corresponds to the highest liquid level of the clean water cavity above the sewage tank. The overflow port is arranged at the position corresponding to the highest liquid level of the clean water cavity above the sewage tank, so that the overflow port is arranged at a position higher than the clean water inlet of the sewage tank all the time. When the water level of the clean water tank reaches the preset height, the surplus clean water can more smoothly flow into the self-cleaning mechanism of the sewage tank through the overflow port under the action of
