The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation of the present utility model.

[0045] In order to be able to detect the water volume in the base station water tank in real time to remind the user, this embodiment provides a base station water tank, and the following will be combined with Figures 1 to 7 to describe the specific content of this embodiment in detail. It should be noted that the height direction and the first direction mentioned in this embodiment both refer to Figure 1 the Z direction in

[0046] As Figures 1 to 6 shown, the base station water tank in this embodiment includes a water tank body 1, a water level detection circuit board 2, and a float assembly 3. A water storage cavity 11 is provided inside the water tank body 1, and the water tank body 1 is used to supply water to the floor sweeper. The water level detection circuit board 2 is arranged on the outer wall surface of the water tank body 1, and a plurality of Hall elements 21 are arranged at intervals along the height direction of the water tank body 1, and each Hall element 21 is electrically connected to the water level detection circuit board 2. The float assembly 3 includes a float 31 and a magnet 32, and the inside of the float 31 is hollow. The float 31 includes a float rod 35 and a float block 36, and the magnet 32 is embedded in the float block 36 of the float 31. The float 31 is located inside the water tank body 1, and the magnet 32 is used to trigger the Hall element 21 to generate a Hall voltage.

[0047] In short, for the base station water tank provided by the present utility model, the water level detection circuit board 2 is installed on the outer wall surface of the water tank body 1, the float assembly 3 is located inside the water tank body 1, and the float 31 embedded with the magnet 32 can float on the water surface of the water storage cavity 11. The height of the float 31 changes with the liquid level. Since a plurality of Hall elements 21 are arranged at intervals along the height direction of the water tank body 1, using the Hall effect principle, the magnet 32 can trigger the Hall element 21 at the corresponding height to generate a Hall voltage, and the water level detection circuit board 2 can obtain the height of the liquid level inside the water tank body 1 by acquiring the Hall voltage of the Hall element 21 at the corresponding height.

[0048] Specifically, a plurality of Hall elements 21 are arranged at intervals along the first direction on the water level detection circuit board 2 to sense the height of the liquid surface inside the water tank body 1. The float 31 is composed of a first component 312 and a second component 313 buckled together, and a heat conduction member 314 is arranged between the contact surfaces of the first component 312 and the second component 313. The first component 312 and the second component 313 are plastic parts, and the first component 312 and the second component 313 can be bonded by heating the heat conduction member 314.

[0049] Furthermore, as Figures 3 to 6As shown in the figure, an installation base 12 with several guide plates 13 is arranged inside the water tank body 1. Each guide plate 13 extends along the first direction. The several guide plates 13 enclose a guide space, and the float 31 is arranged in the guide space. The guide space formed by enclosing the multiple guide plates 13 facilitates guiding the float 31 with the magnet 32 to move up and down only along the first direction, preventing the float 31 from floating at any position in the water storage cavity 11.

[0050] Furthermore, the float assembly 3 further includes a limit mounting base 33 and an elastic buffer 34. The limit mounting base 33 is connected to the installation base 12. One end of the elastic buffer 34 is fixedly connected to the float 31, and the other end of the elastic buffer 34 is fixedly connected to the limit mounting base 33. The float 31, the elastic buffer 34, and the limit mounting base 33 are connected in sequence and inserted into the water storage cavity 11. By adding the elastic buffer 34, the influence of the float 31 floating up and down due to external vibration can be reduced, which helps to accurately detect the liquid level height.

[0051] Exemplarily, the elastic buffer 34 is a spring. The limit mounting base 33 is provided with a sleeve portion 331. One end of the spring is arranged inside the sleeve portion 331, and the other end of the spring is sleeved on the annular flange 311 of the float 31, and / or the installation base 12 is provided with an installation post 121 having a first connection hole 122, and the limit mounting base 33 is provided with a second connection hole 332. The fastener passes through the second connection hole 332 and is connected to the first connection hole 122. Utilizing the self-characteristics of the spring, it can not only suppress the influence of the float 31 by external vibration but also enable the float 31 to lower and reset when the water level drops. By adding the first connection hole 122 and the second connection hole 332, it is convenient to firmly connect the limit mounting base 33 and the installation base 12 through fasteners such as screws or bolts.

[0052] Furthermore, as Figures 3 to 7 shown, a boss 15 is arranged inside the water tank body 1, and a water outlet interface 16 is arranged on the boss 15. The base station water tank further includes a water outlet assembly 4. The water outlet assembly 4 includes a water delivery pipe 41. The water inlet end of the water delivery pipe 41 is located in the water storage cavity 11, and the water outlet end of the water delivery pipe 41 is communicated with the water outlet interface 16. When the sweeping robot approaches the water tank body 1, the water receiving plug of the sweeping robot is inserted into the water outlet interface 16 from bottom to top, and the water in the water storage cavity 11 is sucked into the water storage container of the sweeping robot.

[0053] Optionally, the water outlet assembly 4 further includes a filter 42. The filter 42 is arranged at the water inlet end of the water delivery pipe 41 and is communicated with the water delivery pipe 41. By adding the filter 42, the cleanliness of the water is improved, and the water delivery pipe 41 is prevented from being blocked by particulate matter in the water.

[0054] Further, a limiting insertion post 17 is provided on the inner wall surface of the bottom wall of the water tank body 1. The filter 42 is arranged on the mounting plate 43, and a positioning hole 431 is provided on the mounting plate 43. The limiting insertion post 17 is inserted into the positioning hole 431. By adding the limiting insertion post 17 to the bottom wall of the water tank body 1, it is convenient to set the water inlet end of the water delivery pipe 41 at the bottom of the water tank body 1, and even if the liquid level drops, the liquid can still be sucked continuously.

[0055] Further, a claw portion 18 is provided on the side wall of the boss 15. The water delivery pipe 41 is clamped with the claw portion 18. By adding the claw portion 18, it is convenient to fix the position of the water delivery pipe 41 in the water tank body 1.

[0056] Further, a guiding portion 19 with an arc-shaped guiding groove 191 is provided on the boss 15. The bent section of the water delivery pipe 41 is located in the arc-shaped guiding groove 191. By adding the guiding portion 19, it is convenient to guide the water outlet end of the water delivery pipe 41 to bend downward and connect with the water outlet interface 16 on the boss 15.

[0057] Further, the base station water tank further includes a tank cover 5. The tank cover 5 is hinged to the water tank body 1. The tank cover 5 is provided with a first clamping portion 51, a handle 52 and a ventilation hole 53. A second clamping portion 14 is provided on the outer wall surface of the water tank body 1. The first clamping portion 51 is clamped with the second clamping portion 14. By adding the first clamping portion 51 and the second clamping portion 14, after the tank cover 5 is closed, due to the clamping of the first clamping portion 51 and the second clamping portion 14, it helps the tank cover 5 to be tightly buckled on the water tank body 1.
