Detailed Description

To make the objects, features and advantages of the present invention more obvious and understandable, the embodiments of the present invention are described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by the skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1 to 4, a float 210 structure of a water tank according to an embodiment of the present invention is used for detecting a liquid level in a water tank of a maintenance station, and includes a water tank body 10, a float 210 assembly 20 and a switch assembly 30; the water tank body 10 comprises a water tank 110 and a carrier plate 120 arranged on the top of the water tank 110; the float 210 assembly 20 comprises a float 210 and a lever 220, the float 210 is arranged at a first end of the lever 220, the switch assembly 30 is arranged on the lever 220, the lever 220 is connected with the carrier plate 120 through a support frame, and the float 210 is arranged in the water tank 110; when the lever 220 is rotated, the float 210 moves between the first position and the second position, and the switch assembly 30 moves between the third position and the fourth position, wherein the float 210 is lifted with the water level and moves from the first position to the second position, the switch assembly 30 synchronously moves from the third position to the fourth position, and when the switch assembly 30 is in the fourth position, the switch assembly 30 is turned on.

In the embodiment of the present invention, the support plate 120 is provided with a water inlet and a water pumping port; the water inlet is connected with a water inlet conduit 121, one end of the water inlet conduit 121 is connected with the water inlet, the other end of the water inlet conduit 121 extends into the water tank 110, and the water outlet is provided with soft sealing glue. The sewage is conveyed into the water tank 110 through the water inlet, and after the sewage is fully stored, the water in the water tank 110 is discharged through the water pumping port.

For example, the carrier plate 120 is located on the same plane as the notch of the water tank 110, and the carrier plate 120 is located outside the water tank 110. A part of the space is provided below the carrier plate 120, and the space can be used for installing a pump body, a water inlet pipe, a water outlet pipe and the like.

In the initial state, the water level in the water tank 110 is low, and the float 210 is in contact with the water level or not, and at this time, the float 210 is maintained at the first position and the switch assembly 30 is maintained at the third position, that is, the switch assembly 30 is turned off. As the water level in the water tank 110 rises, the float 210 comes into contact with the water level and the water level lifts the float 210 from the first position to the second position, and in synchronization, the switch assembly 30 moves from the third position to the fourth position, in which the switch assembly 30 is turned on.

For example, the switch assembly 30 includes a hall sensor (not shown in the figures) and a magnetic element 310; the magnetic element 310 is connected with the lever 220, and the hall sensor is arranged on the carrier plate 120; the distance between the magnetic element 310 and the hall sensor is greater when the switch assembly 30 is in the third position than when the switch assembly 30 is in the fourth position.

The Hall sensor is a magnetic sensing element, when a magnetic object moves close to the Hall sensor, the Hall sensor generates Hall effect to change the state of an internal circuit of the switch, and then the on or off of the switch is controlled. Specifically, when approaching a magnetic object, the switch is in an on state; when the magnetic substance is far away, the switch is in an off state.

With continued reference to fig. 1-4, in some embodiments, the float 210 includes a buoyancy surface for contacting a water surface; the buoyancy surface has a set area. For example, the float 210 is a flat structure, such as a circle, square, polygon, or other shape. In the embodiment of the present invention, the shape of the float 210 is not limited. The buoyancy transfer of the water level surface can be improved by arranging a larger buoyancy surface.

In some embodiments, the carrier 120 is further provided with a stop component 130, and the stop component 130 protrudes out of the surface of the carrier 120; when the float 210 moves to the second position, the second end of the lever 220 abuts the stop assembly 130. The stop assembly 130 acts as a limit, and as the float 210 rises, the second end of the lever 220 abuts against the stop assembly 130, so that the lever 220 is prevented from moving continuously.

For example, the soft sealing glue can also be used as the stop component 130, that is, the soft sealing glue protrudes from the surface of the carrier 120; when the float 210 moves to the second position, the second end of the lever 220 abuts against the top end of the soft sealing rubber. The arrangement mode does not need to additionally arrange an installation position of the stop component 130, and the space can be saved.

With continued reference to fig. 1-4, in some embodiments, the lever 220 includes a straight rod portion and a curved portion, the lever 220 having an "L" shape. That is, the lever 220 is not a straight rod structure, and one end of the lever away from the float 210 is bent, so that the installation space can be further saved.

As shown in fig. 5, an embodiment of the present invention provides a water tank, which includes the above-mentioned water tank float 210 structure. For example, the tank further includes a fresh water tank, and the fresh water tank and the sink 110 (foul water tank) are arranged side by side.

An embodiment of the utility model provides a maintenance station, including above-mentioned water tank float 210 structure or above-mentioned water tank.

The embodiment of the utility model provides a pair of water tank float 210 structure, water tank and maintenance station, the maintenance station during operation, along with the continuous increase of water level in the basin 110, float 210 constantly promotes, also the float 210 is along with the water level promotes and is removed to the second place by the primary importance, and simultaneously, because the lever 220 principle, the switch module 30 of lever 220 another part is removed to the fourth place by the third place, when removing to the fourth place, this position is the unsteady limit of float 210, this position trigger switch module 30, also can't continue to pump sewage in the basin 110, and need carry out sewage suction operation. The utility model discloses technical scheme adopts the water level in the float 210 structure monitoring basin 110, and its precision is higher, and then can avoid monitoring wrong condition.
