[0004] In related technologies, cleaning equipment has integrated the functions of replenishing water and replenishing cleaning liquid, but the ratio of cleaning liquid to cleaning water is required to be one to several hundred. In this way, the amount of water provided by the pump body that outputs cleaning water needs to be much larger than the amount of cleaning liquid provided by the pump body that outputs cleaning liquid, resulting in a large output pressure of the pump body that outputs cleaning water, and the phenomenon of clean water flowing back into the container used to hold the cleaning liquid, affecting the cleaning effect of the cleaning equipment.

DETAILED DESCRIPTION

[0028] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. The following description is only for the purpose of illustrating the basic principles of the present invention and is not intended to limit the present invention.

[0029] In order to enable those skilled in the art to understand the present disclosure more clearly, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present disclosure.

[0030] With the development of intelligent cleaning technology, the functions of cleaning equipment (such as sweeping robots, floor scrubbers, etc.) are becoming more and more abundant, and more cleaning equipment has the functions of sprinkling water, mopping the floor and automatically cleaning the mop.

[0031] 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, which results in poor cleaning effect and poor user experience.

[0032] In order to solve the above problems, the functions of replenishing water and cleaning liquid can be integrated on the base and / or mobile host of the cleaning equipment. The liquid in the water tank and the cleaning liquid tank can be output to the liquid outlet in a certain proportion through the pump body, and mixed in the liquid outlet to form a cleaning solution for output, so that the cleaning equipment can achieve better cleaning effect, avoid the situation where stubborn stains need to be cleaned repeatedly or insufficient cleaning as much as possible, and improve the user experience.

[0033] 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. Moreover, since both pump bodies are connected to the liquid outlet parts, the cleaning water will flow back to the cleaning liquid tank, affecting the cleaning effect of the cleaning equipment.

[0034] Based on the above technical problems, the present disclosure 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.

[0035] In a first aspect of the present disclosure, the present disclosure provides a fluid replenishing device for use in cleaning equipment. FIG1 shows a schematic structural diagram of a fluid replenishing device in some embodiments.

[0036] The liquid replenishing device provided by the present disclosure has a first cleaning container 1 containing clean water connected to the liquid outlet 5 through the first pump body 3, so that the first cleaning container 1 can transport clean water to the liquid outlet 5; since the second cleaning container 2 containing clean liquid is connected to the second pump body 4, the first pump body 3 and the liquid outlet 5, the second cleaning container 2 can transport clean liquid to the liquid outlet 5, so that the clean water and the cleaning liquid can be mixed in the liquid outlet 5 to output the cleaning solution, thereby improving the cleaning effect of the cleaning equipment.

[0037] Since the output end of the second pump body 4 is connected to the input end of the first pump body 3, the second pump body 4 is not connected to the liquid outlet part 5. When the first pump body 3 and the second pump body 4 are started at the same time, although the output pressure of the second pump body 4 is lower than the output pressure of the first pump body 3, since the second pump body 4 is not directly connected to the liquid outlet part 5, the pressure of the first pump body 3 cannot be transmitted to the second pump body 4, thereby solving the phenomenon of clean water flowing back to the second cleaning container 2 for containing the cleaning liquid, so that the cleaning solution can be output normally to avoid affecting the cleaning effect of the cleaning equipment.

[0051] The first pump body 3 inputs the clean water in the first cleaning container 1 into the second communicating vessel 8, and the second pump body 4 inputs the cleaning liquid stored in the second cleaning container 2 into the second communicating vessel 8. That is, the clean water and the cleaning liquid can be mixed in the second communicating vessel 8 and then transported to the liquid outlet 5 through the mixing pipe 18. Since the clean water and the cleaning liquid have a longer mixing path, the mixing uniformity can be improved.

[0052] 2 , in some embodiments, one check valve 7 may be provided. Accordingly, there may be one ninth pipeline 17 and the second communicating vessel 8 may be a three-way structure.
