When the water tank is assembled to the main machine of the base station, the propping part of the main machine upwards props against the valve core 73 to open the water outlet 112, so that the base station can supplement clean water for the sweeper. When the water tank is removed from the main machine, the elastic force of the elastic member 74 drives the valve core 73 to move downwards, so that the sealing rubber ring 75 seals the water outlet 112, and water in the water tank cannot flow out.

Referring to fig. 15 to 17, the liquid level detecting device 6 includes a float 61, a connector 62, and a magnet 63. The connector 62 is made of a flexible material. One end of the connecting member 62 is fixed to the side wall 12, and the other end is fixed to the float 61. The box body 1 and the cursory 61 are connected to the connecting piece 62 that utilizes flexible material to make, and the upper and lower floating of cursory 61 relies on connecting piece 62 to buckle the deformation to realize, and connecting piece 62 that flexible material was made does not have the connection gap, has greatly reduced the jam risk, prevents cursory 61 can't rise and fall along with the height of liquid level, causes the condition emergence of liquid level detection device 6 unable detection liquid level. The magnet 63 is provided in the float 61.

The tank body 1 is provided with an induction device, when the water tank is high in water quantity, the liquid level detection device 6 is driven to rise by the buoy 61, the distance between the magnet 63 and the induction device is prolonged, when the water tank is low in water quantity, the liquid level detection device 6 is driven to fall by the buoy 61, the distance between the magnet 63 and the induction device is shortened, the distance between the magnet 63 and the induction device is induced by the induction device, and therefore the water level in the water tank is judged. Alternatively, the sensing means may be a sensor or the like, such as a hall sensor or the like.

Alternatively, the connector 62 may be a hard hinge. Alternatively, the liquid level detection means 6 may also detect the liquid level by means of an electrically conductive contact.

The float 612 is near the top of the tank. A magnet 63 is fixed to the bottom end of the rod-shaped portion. The magnet 63 is adjacent to the bottom wall 11. One end of the connecting member 62 is connected to the rod-shaped portion 611, and the other end is connected to the side wall 12.

Referring to fig. 9, when the tank is a clear water tank, the float 61 is near the bottom of the tank.

Referring to fig. 18 to 22, when the water tank is a sewage tank, the tank body 1 is provided with an air outlet passage 81 and an air inlet passage 91 in the receiving space 111. The water inlet 911 of the water inlet passage 91 and the bottom air outlet 811 of the air outlet passage 81 are located at the bottom of the casing 1. The water outlet 912 of the water inlet channel 91 and the top air outlet 812 of the air outlet channel 81 are located in the storage space 111 and are communicated with the storage space 111. When the air in the accommodating space 111 is sequentially pumped out through the top air outlet 812, the air outlet channel 81 and the bottom air outlet 811, a negative pressure is formed in the accommodating space 111, so that external water flow sequentially enters the accommodating space 111 through the water inlet 911, the water inlet channel 91 and the water outlet 912, and the sewage of the sweeper is sucked into the sewage tank by the wind generated by the fan.

The negative pressure formed in the receiving space 111 may also keep the second cover plate 3 in a closed state.

The sewage tank is in bottom completion and the butt joint of water about the basic station, has realized the basic station and has need not to surround the purpose that can realize complete water function of going up with the water tank, and the novel molding that can make relatively open from this basic station upper strata has reduced the material simultaneously, the cost is reduced.

The tank includes a first assembly 8 and a second assembly 9 assembled to the tank body 1. The first assembly 8 encloses an outlet channel 81. The second assembly 9 encloses a water inlet channel 91. The arrangement of the first assembly piece 8 and the second assembly piece 9 ensures that the inner space of the tank body 1 is smooth and has no cleaning dead angle, thereby being convenient for cleaning the sewage tank.

The case 1 includes a first column 15 and a second column 16 extending from the bottom wall 11 into the accommodation space 111. The first column 15 encloses a first receiving chamber 151. The second cylinder 16 encloses a second receiving chamber 161.

The first assembly 8 is detachably assembled to the first column 15 and is located in the first receiving cavity 151. A first sealing ring 17 is provided between the top end of the first assembly 8 and the top end of the first column 15 to prevent water leakage from the gap between the first column 15 and the first assembly 8.

The second assembly 9 is detachably assembled to the second cylinder 16 and is located in the second receiving chamber 161. A second gasket 18 is provided between the top end of the second assembly 9 and the top end of the second cylinder 16 to prevent water leakage from the gap between the second cylinder 16 and the second assembly 9.

Referring to fig. 23, when the water tank is a sewage tank, the first cover plate 2 is provided with a water blocking plate 27. A water deflector 27 is formed extending downwardly from top wall 23. The water baffle 27 is located between the water outlet 912 of the water inlet channel 91 and the top air outlet 812 of the air outlet channel 81, and the bottom end of the water baffle 27 is lower than the water outlet 912 and the top air outlet 812. When the liquid level of the sewage tank is high, the air flow generated by the top air outlet 812 can be prevented from bringing the sewage sprayed out of the water outlet 912 into the fan to damage the fan when the air flow rapidly flows at the upper part of the water tank.
