Examples of these preferred embodiments are illustrated in the accompanying drawings. The embodiments of the utility model shown in the drawings and described in accordance with the drawings are merely exemplary and the utility model is not limited to these embodiments.

It should be noted here that, in order to avoid obscuring the present utility model due to unnecessary details, only structures and/or processing steps closely related to the solution according to the present utility model are shown in the drawings, while other details not greatly related to the present utility model are omitted.

The embodiment of the utility model firstly provides a water storage device which is applied to a cleaning robot. Referring to fig. 1 to 3, a water storage device 100 in the present embodiment mainly includes a tank 10, and a water storage chamber 20 and a water injection assembly 30 disposed in the tank 10. Wherein the water injection assembly 30 communicates with the water storage chamber 20 for interfacing with an external water supply assembly, and injecting a cleaning medium such as water or detergent supplied from the water supply assembly into the water storage chamber 20.

As a preferred solution, in this embodiment, as shown in fig. 2 and 3, the dust collecting chamber 40 is further integrated in the water storage device 100; the dust collection chamber 40 is provided at the middle of the tank 10, and the water storage chamber 20 is provided around the dust collection chamber 40 in the tank 10. Based on the above structure, the water storage device 100 in this embodiment can be understood as an integrated device for collecting dust and storing water, which is beneficial to reduce the volume of the cleaning robot. As shown in fig. 1 and 3, the dust collecting port 41 is disposed on the case 10 and is in communication with the dust collecting chamber 40, the baffle 42 is disposed on the dust collecting port 41 and can be opened or closed, and the dust collecting port 4 is used for docking with an external dust collecting assembly to collect dust in the dust collecting chamber 40 into an external storage unit.

Referring to fig. 2 to 7, the water injection assembly 30 includes a mounting base 1 and a water injection valve tube 2. The mounting seat 1 is provided with a first cavity 11 and a second cavity 12 which are isolated from each other, and the water injection valve pipe 2 is clamped in the mounting seat 1 and extends from the first cavity 11 to the second cavity 12.

Wherein, the water injection valve pipe 2 is provided with a water inlet 21 positioned in the first cavity 11 and a water outlet 22 positioned in the second cavity 12. The first chamber 11 has an open portion 111 so that the water inlet 21 is exposed from the tank 10, thereby enabling an external water supply assembly to be docked with the water injection valve tube 2. The second chamber 12 is provided therein with a flow passage 121 communicating to the water storage chamber 20.

Further, in the present embodiment, the water injection valve tube 2 is provided therein with the blocking member 3 driven based on an elastic force. The occluding member 3 is configured to: when the plugging member 3 is not acted by external force, the plugging member is driven to move to a first position to block the channel between the water inlet 21 and the water outlet 22; when subjected to an external force (such as water supply pressure or thrust of a water supply assembly), the closure member 3 is driven to move to a second position to communicate the passage between the water inlet 21 and the water outlet 22.

The structure of the water injection assembly 30 based on the above structure: when it is required to replenish the water storage chamber 20 with the cleaning medium, the cleaning robot is controlled to move so that the water injection assembly 30 is docked with an external water supply assembly. An external water supply assembly injects cleaning medium from the water inlet 21, at which time the blocking member 3 is driven to move to the second position under the action of external force, so that the water inlet 21 and the water outlet 22 communicate. The cleaning medium injected from the water inlet 21 reaches the second chamber 12 through the water outlet 22, and is smoothly injected into the water storage chamber 20 through the flow passage 121 in the second chamber 12. When the cleaning medium is injected, the external water supply assembly stops supplying the cleaning medium, the blocking member 3 is not acted by external force, and moves to the first position under the driving of the elastic force of the blocking member, so that the channel between the water inlet 21 and the water outlet 22 is blocked; the second chamber 12 is well sealed except for the flow passage 121 communicating with the water storage chamber 20. At this time, when the cleaning robot moves, vibrates or accidentally falls down during operation, the cleaning medium in the water storage chamber 20 can be effectively prevented from being scattered or leaked through the water injection assembly 30.

In a preferred embodiment, the water filling valve tube 2 comprises a first tube portion 23 and a second tube portion 24. The first pipe portion 23 is located in the first cavity 11, the first end of the first pipe portion 23 faces the opening 111, the second end of the first pipe portion 23 is connected with the first end of the second pipe portion 24, and the second end of the second pipe portion 24 extends into the second cavity 12.

Further, the inner diameter of the first tube portion 23 gradually decreases from the first end toward the second end thereof, and the inner diameter of the second tube portion 24 is larger than the inner diameter of the second end of the first tube portion 23. Wherein the first pipe portion 23 is formed as a water inlet 21, a water outlet 22 is opened on a side wall of the second pipe portion 24, and the blocking member 3 is fitted in the second pipe portion 24.

The structure of the water injection valve pipe 2 based on the above: when the plugging member 3 is not acted by external force, it is driven to move to the first end of the second pipe portion 24 to block the channel between the water inlet 21 and the water outlet 22; when an external force is applied, the blocking member 3 is driven to move toward the second end of the second pipe portion 24, thereby communicating the passage between the water inlet 21 and the water outlet 22.

In addition, as described above, the inner diameter of the first tube portion 23 gradually decreases from the first end toward the second end thereof, that is, the first tube portion 23 has a horn-like opening structure. The arrangement is that the water injection valve pipe 2 has larger fault tolerance rate when being in butt joint with an external water supply assembly, or the water injection valve pipe 2 has certain self-correcting capability when being in butt joint with the external water supply assembly. Therefore, the water injection assembly 30 can be more smoothly docked with the external water supply assembly when the operation of automatically injecting the cleaning medium is performed.
