For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0038] like Figure 1 As shown, a cleaner, taking the floor brush shown in the figure as an example, the floor brush includes a floor brush body 6, a curved pipe assembly 7 connected to the floor brush body 6, and a water tank 1 connected to the curved pipe assembly 7. The water tank 1 is installed below the curved pipe assembly 7 and is located at the rear of the floor brush 6.

[0039] The water tank 1 includes a top plate with a water inlet 11 and a bottom plate with a water outlet 12. An automatic opening and closing component is arranged inside the water tank 1 and at the water outlet 12. A cleaning component 3 in contact with the water outlet 12 is arranged at the bottom of the water tank 1. The cleaning component 3 is adsorbed on the bottom plate of the water tank 1 through a magnetic component 4. Fig.11As shown, water flows out from the water outlet 12 to wet the cleaning component 3, thereby improving the cleaning ability. In the embodiment of the present invention, the cleaning component 3 is a rag.

[0040] Embodiment 1:

[0041] like Figure 2 , 3 As shown, the automatic opening and closing assembly includes a fixing member 21 fixedly connected to the bottom plate of the water tank 1, a piston member 22 movably connected to the fixing member 21, a movable member 23 for closing the water outlet 12 at one end of the piston member 22, and an elastic member 24 connected to the piston member 22. In order to improve the stability of the automatic opening and closing assembly, the piston member 22 can be vertically arranged in the manner shown in the figure. The movable member 23 is arranged at the other end of the piston member 22, and under the action of gravity, the piston member 22 is pushed so that one end of the piston member 22 closes the water outlet 12, while the elastic member 24 always gives an elastic force to one end of the piston member 22 to separate from the water outlet 12, and the opening and closing of the water outlet 12 is realized under the cooperation of the two. The elastic member 24 can be connected between the water outlet 12 and the piston member 22 in the manner shown in the figure, or can be connected between the fixing member 21 and the piston member 22 and other methods. In order to improve the gravity and flexibility of the movable member 23, the movable member 23 can be a metal sphere, such as a steel ball. A sealing member 25 is disposed at one end of the piston member 22 , and the sealing member 25 matches the shape of the water outlet 12 .

[0042] like Figure 2 , 3 As shown, in order to prevent the movable member 23 from being separated from the automatic opening and closing assembly, the fixed member 21 has a space 211 for placing the movable member 23. The space 211 is formed by the upper end of the fixed member 21 and the top plate of the water tank 1. The bottom of the space 211 has a lowest point. The bottom of the space 211 is similar to a funnel shape, and the other end of the piston member 22 extends into the space 211. When the water tank 1 is stationary and the bottom plate is placed horizontally, the movable member 23 is located at the lowest point of the space 211. The movable member 23 can contact the other end of the piston member 22 and push the piston member 22, so that one end of the piston member 22 blocks the water outlet 12 and closes the water outlet 12; when mopping the floor, the water tank 1 is shaken, and the movable member 23 is shaken by force and leaves the lowest point of the space 211. The piston member 22 is affected by the elastic force of the elastic member 24, and one end of the piston member 22 leaves the water outlet 12, so that a water outlet gap is formed between the piston member 22 and the water outlet 12, and the water in the water tank 1 can flow out.

[0043] The working principle of the first embodiment is described in detail:

[0044] like Figure 2 , 3As shown, water is injected into the water tank 1 from the water inlet 11. When the cleaner is stationary, the movable part 23 is located at the lowest point of the space 211, pushing the piston part 22 so that one end of it closes the water outlet 12, and water cannot flow out; when the cleaner is used for cleaning, the cleaner is dragged back and forth, and the movable part 23 leaves the lowest point of the space 211 due to the shaking, and the elastic part 24 bounces the piston part 22 so that one end of it opens the water outlet 12, and water flows out from the water outlet 12, so that water can be added to the cleaning component 3 while cleaning.

[0045] Embodiment 2:

[0046] like Figure 4 , 5 As shown, the automatic opening and closing assembly includes a movable member 23, a first limiting member 26, a second limiting member 27, and a limiting cover 28. The movable member 23 directly opens and closes the water outlet 12, and a sealing member is provided at the water outlet 12. When the cleaner is stationary, the movable member 23 blocks the water outlet 12 under the action of gravity to close it; when the cleaner moves, the movable member 23 is forced to move away from the water outlet 12 to open it. In order to increase the gravity and flexibility of the movable member 23, the movable member 23 can be a metal sphere, such as a steel ball.

[0047] The first stopper 26 and the second stopper 27 are arranged on the bottom plate of the water tank 1. The first stopper 26 and the second stopper 27 are formed by the bottom plate protruding toward the top plate. The water outlet 12 is located between the first stopper 26 and the second stopper 27. The floor brush can be placed horizontally or vertically. When the floor brush is placed horizontally (such as placed on the ground), the height of the upper surface of the bottom plate of the water tank 1 gradually decreases from the second stopper 27 to the water outlet 12, and the water outlet 12 is located at the lowest point of the space 211. Figure 4 When the brush is placed vertically (such as hanging on the wall), the bottom plate of the water tank 1 is in a vertical state, the first limit member 26 is located below, the second limit member 27 is located above, such as Figure 5 The limiting cover 28 is disposed above the first limiting member 26 and the second limiting member 27 (with the conventional floor brush being in a horizontal state as a reference), and the first limiting member 26, the second limiting member 27 and the limiting cover 28 enclose a space 211 for placing the movable member 23, and the movable member 23 moves within the range of the space 211.

[0048] When the cleaner is stationary and the bottom surface of the water tank 1 is horizontal, the movable part 23 is pressed against the first limit member 26 by gravity and blocks the water outlet 12; when the cleaner is stationary and the bottom surface of the water tank 1 is vertical, the movable part 23 is supported on the first limit member 26 and the limit cover 28 by gravity and blocks the water outlet 12; when mopping the floor, the water tank 1 is caused to shake, and the movable part 23 is forced to shake and leave the lowest point of the space 211, so that a water outlet gap is formed between the movable part 23 and the water outlet 12, and the water in the water tank 1 can flow out.

[0049] The working principle of the second embodiment is described in detail:

[0050] like Figure 4 , 5 As shown, water is injected into the water tank 1 from the water inlet 11. When the cleaner is stationary, the movable part 23 abuts or is supported on the first limit part 26 and blocks the water outlet 12, so that water cannot flow out. When the cleaner is used for cleaning, the cleaner is dragged back and forth, and the movable part 23 leaves the water outlet 12 due to the shaking, and water flows out from the water outlet 12, so that water can be added to the cleaning component 3 while cleaning.

[0051] The bottom plate of the water tank 1 in the first and second embodiments has various structural forms:

[0052] like Figure 6 , 7 As shown, in the first or second embodiment, a plurality of water outlets 12 are provided on the bottom plate of the water tank 1, and each water outlet 12 is provided with an automatic opening and closing component. The figure shows that two water outlets are provided, and the two water outlets are symmetrically arranged.

[0053] like Figure 8-10 As shown, in the first or second embodiment, only one water outlet 12 is provided on the bottom plate of the water tank 1, and the cleaner further comprises a diverter plate 5 provided on the bottom plate of the water tank 1, the diverter plate 5 having a diverter inlet and a plurality of diverter outlets 51, the diverter inlet is connected to the water outlet 12, the diverter outlets 51 are in contact with the cleaning component 3, and the diverter outlets 51 can be evenly distributed. In this embodiment, a diverter groove 13 for placing the diverter plate 5 is provided on the floor of the water tank 1, so that the bottom plate of the water tank 1 is flat.

[0054] The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with the technology to understand the content of the present invention and implement it accordingly, and they cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the protection scope of the present invention.
