Detailed Description

The present application is described in further detail below in conjunction with figures 1-3.

The embodiment of the application discloses a water supply device with an automatic power-off function. Referring to fig. 1, the water supply apparatus with an automatic power-off function includes a water tank 1 and a drain pump 2 for draining the water tank 1. A water outlet pipe 21 is fixed on one side of the water tank 1, and a drainage pump 2 is arranged on the water outlet pipe 21.

Referring to fig. 1 and 2, a partition plate 11 is fixed in the water tank 1, and the distance between the bottom of the partition plate 11 and the inner bottom surface of the water tank 1 is 10-20cm; the through holes between the partition plate 11 and the inner bottom surface of the water tank 1 are water inlet holes 12 for communicating the areas on both sides of the partition plate 11. The partition 11 divides the area inside the water tank 1 into a water storage area 13 and a water level area 14.

Referring to fig. 1 and 2, a floating plate 3 is slidingly connected in a vertical direction in a water level region 14 of the water tank 1. The side wall of the water tank 1 is provided with a dovetail groove 31, and the side wall of the floating plate 3 is fixedly provided with a dovetail block 32 which can vertically move with the dovetail groove 31.

Since the water storage area 13 is communicated with the water level area 14, when the water level in the water storage area 13 falls, the water level in the water level area 14 can keep falling synchronously, and the floating plate 3 can gradually fall along with the falling of the water level.

Referring to fig. 2 and 3, a first chute 33 is formed in a side wall of the water tank 1 located at one side of the water level region 14, and the water tank 1 is slidably connected with a contact piece 34 along the width direction of the floating plate 3 through the first chute 33. An abutting plate 35 which can be contacted with the abutting plate 34 is fixed on one side of the floating plate 3 close to the abutting plate 34, and inclined planes 36 which can be mutually abutted are respectively formed on the top of the abutting plate 34 and the opposite inner sides of the bottom of the abutting plate 35. The abutment piece 34 is wrapped with rubber on the periphery side for preventing water in the water tank 1 from entering the first chute 33.

Referring to fig. 2 and 3, a switch rotor 22 is fixed to the bottom of the contact piece 34, and a switch stator 23 that can be in electrical contact with the switch rotor 22 is fixed to the inner bottom surface of the first chute 33. The switch rotor 22 is electrically connected to the power source, and the switch stator 23 is electrically connected to the drain pump 2.

After the floating plate 3 descends along with the water level, the floating plate 3 contacts with the abutting piece 34 through the inclined surface 36 and pushes the abutting piece 34 to move. Before the contact piece 34 moves, the switch rotor 22 and the switch stator 23 are in electrical contact. After the floating plate 3 descends and pushes the moving plate to move, the switch moving plate 22 and the switch fixed plate 23 are disconnected, so that the drain pump 2 stops working.

Referring to fig. 3, a first spring 24 is fixed to a side of the abutment piece 34 away from the floating plate 3, and an end of the first spring 24 away from the abutment piece 34 is fixedly connected with an inner wall of the first chute 33 on a side close to the drain pump 2.

The first spring 24 provides the elastic force on one side of the abutting plate 35 for the abutting plate 34, so that after the abutting plate 34 is separated from the abutting plate 35, the abutting plate 34 is driven by the first spring 24 to return to one side close to the abutting plate 35.

Referring to fig. 3, a second chute 25 is formed on the top surface of the first chute 33, and a limiting piece 26 is connected to the side wall of the water tank 1 in a sliding manner along the vertical direction through the second chute 25. The top end of the limiting piece 26 is fixedly provided with a second spring 27, and the top end of the second spring 27 is fixedly connected with the top wall of the second chute 25. The top surface of the abutting piece 34 is provided with a limiting hole 37 for penetrating the limiting piece 26.

In the initial state, the limit piece 26 is abutted with the top surface of the abutting piece 34; when the abutment piece 34 moves, the abutment piece 34 moves to be spliced with the limiting hole 37 of the limiting piece 26, so that a limiting effect is provided for the abutment piece 34.

The implementation principle of the water supply device with the automatic power-off function is as follows:

when the water level of the water tank 1 is reduced to the bottom of the water tank 1 in the continuous draining process, the water level of the water storage area 13 and the water level area 14 are consistent, and the abutting plate 35 can be lowered along with the water level to be in contact with the abutting plate 34 and push the abutting plate 34 to move.

During the movement of the contact piece 34, the switch moving piece 22 and the switch moving piece 23 are disconnected, so that the water pump stops working, and the water tank 1 stops draining water outwards.

After the abutting piece 34 moves, the limiting piece 26 above the abutting piece 34 moves downwards and is spliced with the limiting hole 37 on the abutting piece 34, so that a limiting effect is provided for the limiting piece 26, the possibility that the limiting piece 26 moves due to the up-and-down movement of the floating plate 3 is reduced, and the switch moving piece 22 and the switch moving piece 23 are in false touch.

The foregoing are all preferred embodiments of the present application, and are not intended to limit the scope of the present application in any way, therefore: all equivalent changes in structure, shape and principle of this application should be covered in the protection scope of this application.
