Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments.

[0027] The present application provides a liquid storage structure applied to a cleaning device, which can be used to store liquid, which can be clean water, a mixture of clean water and cleaning agent, sewage and the like, and can sterilize and disinfect the liquid stored in the liquid storage structure to avoid the breeding of bacteria in the liquid storage structure.

[0028] Please refer to Figure 1 , Figure 1 The structure of the liquid storage structure 100 in the present application is shown, which comprises a liquid storage tank 10 and a sterilization module 20 installed in the liquid storage tank 10.

[0029] The shape of the liquid storage tank 10 can be various, which can be a square, a cylinder and other regular shapes, or can be irregularly shaped. Considering that the liquid storage tank 10 needs to be assembled to the cleaning device 1000, the shape of the liquid storage tank 10 is preferably a regular shape, which is beneficial to the installation of the liquid storage tank 10 to the cleaning device 1000.

[0030] The liquid storage tank 10 can be composed of a tank body and a tank cover. The tank body is a cavity structure with one end open, and the tank cover is used to cover the opening of the tank body to form a sealed liquid storage space together with the tank body. The assembly mode of the tank cover and the tank body can be various, such as threaded connection, plug-in connection and other connection modes, which will not be listed here.

[0031] The first liquid storage space 10a and the second liquid storage space 10b are arranged in the liquid storage tank 10 and are in communication with each other. The first liquid storage space 10a and the second liquid storage space 10b are two spaces in containment, that is, the second liquid storage space 10b can be located in the first liquid storage space 10a. At this time, the first liquid storage space 10a and the second liquid storage space 10b can be connected through hole structure or pipeline structure. The second liquid storage space 10b is arranged in the first liquid storage space 10a, so that the structure of the liquid storage tank 10 is more compact.

[0032] The sterilization module 20 can sterilize and disinfect the liquid. The sterilization module 20 can be of various types. For example, when the sterilization module 20 sterilizes tap water, the sterilization module 20 can be an electrolysis structure. The electrolysis structure can generate active oxygen clusters and hypochlorous acid and other disinfecting molecules with high oxidation-reduction performance by electrolyzing tap water, so as to disinfect the water in the liquid storage tank 10 and inhibit bacteria. The method has a relatively low cost. For another example, the sterilization module 20 can also be a UV lamp. The UV lamp can generate ultraviolet rays that can kill toxic substances after being powered on, so as to better play a role in sterilization and inhibition of viruses.

[0033] The sterilization module 20 is installed in the second liquid storage space 10b to sterilize and disinfect the liquid in the second liquid storage space 10b. It should be noted that the liquid in the liquid storage tank 10 can flow in two directions in the first liquid storage space 10a and the second liquid storage space 10b. The following will be described in detail through specific examples.

[0034] The liquid in the liquid storage tank 10 can flow from the second liquid storage space 10b to the first liquid storage space 10a. At this time, the second liquid storage space 10b can be in communication with the liquid inlet pipeline, and the first liquid storage space 10a can be in communication with the liquid outlet pipeline. Since the sterilization module 20 is installed in the second liquid storage space 10b, the liquid entering the second liquid storage space 10b can be sterilized and disinfected by the sterilization module 20, so that the liquid stored in the first liquid storage space 10a or flowing out of the first liquid storage space 10a is sterile.

[0035] The liquid in the liquid storage tank 10 can flow from the first liquid storage space 10a to the second liquid storage space 10b. At this time, the first liquid storage space 10a can be in communication with the liquid inlet pipeline, and the second liquid storage space 10b can be in communication with the liquid outlet pipeline. Since the sterilization module 20 is installed in the second liquid storage space 10b, the liquid flowing from the first liquid storage space 10a to the second liquid storage space 10b is sterilized and disinfected by the sterilization module 20, so that the liquid stored in the second liquid storage space 10b or flowing out of the second liquid storage space 10b is sterile.

[0036] It should be noted that no matter whether the liquid flows from the first liquid storage space 10a to the second liquid storage space 10b or flows from the second liquid storage space 10b to the first liquid storage space 10a, the liquid needs a driving force. The driving force can be the gravity of the liquid itself, or can be provided by a pressurization structure such as a gas pump or a vacuum pump.

[0037] When the liquid flows by relying on its own gravity, at least one of the first liquid storage space 10a and the second liquid storage space 10b is in communication with the external environment at this time, which makes that there is no air pressure difference between the first liquid storage space 10a and the second liquid storage space 10b, and the liquid can flow from the one located at a high position to the one located at a low position under the action of its own gravity.

[0038] When the liquid flows by relying on the air pressure difference, at this time the entire liquid storage tank 10 is in a sealed state, one of the first liquid storage space 10a and the second liquid storage space 10b is in communication with the outside, and the pressurizing structure pressurizes the one of the first liquid storage space 10a and the second liquid storage space 10b which is not in communication with the outside, so as to drive the liquid into the one of the first liquid storage space 10a and the second liquid storage space 10b which is in communication with the outside, and finally flow to the outside.

[0039] In the present application, by arranging the first liquid storage space 10a and the second liquid storage space 10b located in the first liquid storage space 10a in the liquid storage tank 10, the second liquid storage space 10b is in communication with the first liquid storage space 10a and is provided with the sterilization module 20, which can effectively sterilize and disinfect the liquid in the second liquid storage cavity. Compared with the prior art of directly placing the sterilization module 20 in a relatively large liquid storage space to sterilize and disinfect the liquid, the sterilization module 20 in the present application can gradually sterilize and disinfect the liquid entering the liquid storage tank 10 through the arrangement of the first liquid storage space 10a and the second liquid storage space 10b, so as to ensure the sterilization and disinfection effect of the sterilization module 20, thereby avoiding the breeding of bacteria in the liquid storage tank 10.

[0040] Considering that the sterilization module 20 is arranged in the second liquid storage space 10b, in order to ensure that the liquid entering the second liquid storage space 10b is sterilized and disinfected by the sterilization module 20, in some embodiments of the application, please refer to Figure 1 The liquid storage tank 10 is also provided with a liquid inlet 11 in communication with the second liquid storage space 10b, and the sterilization module 20 is located below the liquid inlet 11. In this way, the liquid entering the second liquid storage space 10b through the liquid inlet 11 needs to be sterilized and disinfected by the sterilization module 20 in the sterilization tank first and then stored in the second liquid storage space 10b and the first liquid storage space 10a.

[0041] Further, since the first liquid storage space 10a and the second liquid storage space 10b are arranged in communication, the first liquid storage space 10a and the second liquid storage space 10b constitute a communicating vessel structure, thus the liquid amount stored by the first liquid storage space 10a and the second liquid storage space 10b is determined by the lower one of the highest liquid levels in the first liquid storage space 10a and the second liquid storage space 10b, and arranging the liquid inlet 11 at the top of the second liquid storage space 10b can ensure that the highest liquid level in the second liquid storage space 10b is high enough, so that when the liquid outlet of the first liquid storage space 10a is high enough, both the first liquid storage space 10a and the second liquid storage space 10b can contain enough liquid.

[0042] It should be noted that the sterilization module 20 can be arranged adjacent to the liquid inlet 11 at the second liquid storage space 10b, the sterilization module 20 can also be arranged at the bottom of the second liquid storage space 10b away from the liquid inlet 11, the sterilization module 20 can also be arranged at other positions between the bottom and the liquid inlet 11 of the second liquid storage space 10b, which is not specifically limited here. Preferably, the sterilization module 20 is arranged at the bottom of the second liquid storage space 10b, so arranged, it is convenient to fix the sterilization module 20.

[0043] Further, referring to Figure 2 The liquid storage structure 100 further comprises a flow guide plate 30, which is inclinedly arranged in the second liquid storage space 10b, i.e. the flow guide plate 30 is arranged from the top of the second liquid storage space 10b to the bottom of the second liquid storage space 10b, the surface of the flow guide plate 30 facing the liquid inlet 11 is used to guide the liquid to the sterilization module 20, so that it can be ensured that the liquid entering the second liquid storage space 10b can basically be sterilized and disinfected by the sterilization module 20 before flowing to the second liquid storage space 10b, avoiding the liquid entering the second liquid storage space 10b without being sterilized and disinfected by the sterilization module 20 before entering the first liquid storage space 10a.

[0044] It should be noted that the sterilization module 20 needs a certain time to sterilize and disinfect the liquid, if the liquid entering the second liquid storage space 10b contacts the sterilization module 20 for a very short time, the problem of incomplete killing of bacteria in the liquid will occur, therefore, in some embodiments of the present application, referring to Figure 2 The first liquid storage space 10a further comprises a third liquid storage space 10c, which communicates the first liquid storage space 10a and the second liquid storage space 10b, the position where the third liquid storage space 10c communicates with the second liquid storage space 10b is lower than the position where the third liquid storage space 10c communicates with the first liquid storage space 10a.

[0045] Since the liquid in the second liquid storage space 10b needs to pass through the third liquid storage space 10c when entering the first liquid storage space 10a, the third liquid storage space 10c can form a space for temporarily storing liquid. In addition, since the position where the third liquid storage space 10c communicates with the first liquid storage space 10a is higher than the position where the second liquid storage space 10b communicates with the third liquid storage space 10c, the third liquid storage space 10c needs to store a certain amount of liquid before discharging liquid into the first liquid storage space 10a. Therefore, the contact time of the liquid with the sterilization module 20 can be ensured, and the sterilization module 20 can kill all bacteria in the liquid.

[0046] It should be further noted that when the air pump stops working, the liquid in the third liquid storage space 10c will also flow back to the second liquid storage space 10b. In this way, secondary sterilization and disinfection can be achieved, thereby improving the sterilization and disinfection effect.

[0047] Further, referring to Figure 2 , the liquid outlet of the third liquid storage space 10c is higher than the lowest liquid level of the first liquid storage space 10a and the lowest liquid level of the second liquid storage space 10b, and the liquid outlet of the third liquid storage space 10c is lower than the highest liquid level of the first liquid storage space 10a and the highest liquid level of the second liquid storage space 10b. In this way, on the one hand, it is beneficial to the flow of liquid in the second liquid storage space 10b to the third liquid storage space 10c after sterilization and disinfection, and on the other hand, it can slow down the flow of liquid in the first liquid storage space 10a into the second liquid storage space 10b. In addition, it can also ensure that the liquid storage tank can store enough liquid.

[0048] Further, the second liquid storage space 10b and the third liquid storage space 10c are located above the bottom of the first liquid storage space 10a. In this way, it can be ensured that the liquid in the first liquid storage space 10a will not flow back to the third liquid storage space 10c when the liquid in the first liquid storage space 10a does not reach the highest liquid level of the third liquid storage space 10c. In this way, the problem of the liquid after sterilization and disinfection flowing back to the first liquid storage space 10a and being contaminated by the liquid that has not been sterilized and disinfected can be avoided.

[0049] Based on the above embodiments, there are many ways to form the first liquid storage space 10a, the second liquid storage space 10b, and the third liquid storage space 10c in the liquid storage tank 10. The first liquid storage space 10a can be formed by a cavity inside the liquid storage tank 10, the second liquid storage space 10b and the third liquid storage space 10c can be formed by a partition, and the second liquid storage space 10b and the third liquid storage space 10c can also be formed by a tank structure. The specific formation of the first liquid storage space 10a, the second liquid storage space 10b, and the third liquid storage space 10c is not limited here.

[0050] Preferably, the first liquid storage space 10a, the second liquid storage space 10b and the third liquid storage space 10c are formed by the box structure. Specifically, please refer to Figures 1-3 The liquid storage tank 10 comprises an outer box 12 and an inner box 13 installed in the outer box 12, the inner space of the outer box 12 forms the first liquid storage space 10a, the inner box 13 is L-shaped and has a first liquid storage part 131 extending upward and downward and a second liquid storage part 132 extending horizontally, the space in the first liquid storage part 131 forms the second liquid storage space, and the space in the second liquid storage part 132 forms the third liquid storage space. In this way, the assembly of the liquid storage tank 10 is facilitated, and the production and manufacturing of the liquid storage tank 10 are facilitated.

[0051] It is worth noting that when the inner box 13 is installed in the inner space of the outer box 12, the box wall of the inner box 13 is fixedly connected with the box wall of the outer box 12, so that the box wall of the inner box 13 and the outer box 12 can be shared, which not only saves materials, but also makes the overall structure of the liquid storage tank 10 more compact.

[0052] Please refer to Figure 4 and Figure 5 The present application provides a cleaning device 1000, which comprises a cleaning robot and / or a cleaning base station, the cleaning device 1000 comprises a robot body 200 and a liquid storage structure 100 installed on the robot body 200, the specific structure of the liquid storage structure 100 is referred to the above-mentioned embodiments, since the cleaning device 1000 adopts all the technical solutions of the above-mentioned embodiments, it at least has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be repeated here.

[0053] It should be noted that the cleaning robot can be a sweeping robot, a mopping robot, a sweeping and mopping integrated robot and other devices capable of cleaning the ground. The base station is used with the cleaning robot, which can clean the mop of the cleaning robot, and can also charge the cleaning robot, and the base station can also perform other actions on the cleaning robot, which is not limited here.
