DETAILED DESCRIPTION

[0026] In order to make the technical personnel in the technical field to which the present application belongs to understand the present application more clearly, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0027] In the related art, the cleaning equipment mainly includes a mobile host and a base station. The base station can replenish water for the mobile host, or the mobile host itself can replenish water, but the mobile host can only use clean water for cleaning. When encountering stubborn stains, it often requires repeated cleaning, and the cleaning effect is not good, and the user experience is also poor.

[0028] In order to solve the above problems, the base and mobile host of the cleaning equipment have integrated the functions of replenishing water and cleaning liquid. The liquid in the water tank and the cleaning liquid tank is output in a certain proportion through the corresponding pump body to form a cleaning solution output, so that the cleaning equipment can achieve better cleaning effect, avoid the situation where stubborn stains need repeated cleaning or insufficient cleaning, and improve the user experience.

[0029] However, in actual use, since the ratio of cleaning liquid to cleaning water is required to be one to several hundred, the amount of water provided by the cleaning water pump needs to be much greater than the amount of cleaning liquid provided by the cleaning liquid pump, resulting in a higher pressure provided by the cleaning water pump, which will cause the cleaning water to flow back into the cleaning liquid tank, affecting the cleaning effect of the cleaning equipment.

[0030] Based on the above technical problems, the present application provides a liquid replenishing device and a cleaning device, which aim to solve the problem of cleaning water flowing back into the container for containing cleaning liquid to at least a certain extent, so as to avoid affecting the cleaning effect of the cleaning device.
