CONTENT OF UTILITY MODEL

[0005] The utility model provides a water purifier detection lifting water changing structure of non-continuous water supply, and is suitable for the detection of water purifier of non-continuous water supply, which needs to lift water tank and then put down to activate flushing function, facilitates water changing and activation of automatic flushing function during detection, and improves efficiency.

[0006] To solve the above technical problems, the technical scheme adopted by the utility model is as follows:

[0007] A water purifier detection lifting water changing structure of non-continuous water supply, the water tank of water purifier is movably matched on one side of water purifier main body, and the water purifier detection lifting water changing structure comprises a lifting device and a water changing device;

[0008] The lifting device comprises a support, a reversible motor, a winding shaft, a lifting wire, a first adhesive hook and a transverse limiting belt;

[0009] The water purifier is arranged at the bottom of the support, the reversible motor is arranged at the top of the support, and the winding shaft is arranged on the rotating shaft of the reversible motor; the number of the first adhesive hooks is two, and the two first adhesive hooks are oppositely adhered to the two sides of the water tank; one end of the lifting wire is fixed on the winding shaft, and the other end is branched into two lifting sub-wires; the end portions of the two lifting sub-wires are respectively provided with lifting rings, and the lifting rings of the two lifting sub-wires are movably hung on the two first adhesive hooks; and the transverse limiting belt is detachably sleeved outside the water purifier body and the water tank.

[0010] The water changing device comprises a water changing pipe, a water pumping pipe and a water pumping pump; one end of the water changing pipe is connected with a water source, and the other end of the water changing pipe extends into the water tank; the water changing pipe is provided with an electromagnetic valve; one end of the water pumping pipe extends into the bottom of the water tank, and the other end of the water pumping pipe leads to a sewage pool; and the water pumping pump is arranged on the water pumping pipe.

[0011] The present application is suitable for detecting a water purifier with a non-continuous water source supply which needs to be lifted and then lowered to activate the flushing function. The water purifier with the non-continuous water source supply is generally lifted upward by 2-5 cm and then lowered to activate the flushing function. The water purifier comprises a water purifier body and a water tank movably arranged on one side of the water purifier body.

[0012] The reversible motor refers to a motor which can rotate in both directions.

[0013] During the detection, the electromagnetic valve is opened, water is injected into the water tank through the water changing pipe, the electromagnetic valve is closed when the liquid level in the water tank reaches the highest water level (sensed by the highest water level sensor), the reversible motor is started, the water tank is lifted upward by 2-5 cm by the clockwise rotation of the reversible motor, and then the water tank is returned to the original position by the counterclockwise rotation of the reversible motor, the flushing function of the water tank is activated, the water purifier stops water production when the liquid level in the water tank reaches the lowest water level (sensed by the lowest water level sensor), the waste water in the water tank is discharged by starting the water pumping pump, the water pumping pump is closed after the water pumping is completed, and one cycle of water production operation is completed, and then the above-mentioned water production operation is repeated until the test is completed. In this way, the lifting time can be effectively reduced, and the service life of the device can be better ensured.

[0014] As another operation method, the water tank can also be activated in the following sequence: the water tank is lifted upward by 2-5 cm by starting the reversible motor when the liquid level in the water tank reaches the lowest water level; then the waste water in the water tank is discharged by starting the water pumping pump, and the water pumping pump is closed after the water pumping is completed; the electromagnetic valve is opened to inject water into the water tank to the highest liquid level, and the electromagnetic valve is closed; the water tank is lowered by 2-5 cm to return to the original position (placed on the water purifier body to activate the flushing function) by starting the reversible motor, the flushing system of the water tank is activated, the above-mentioned water production operation is repeated, and the test is completed until the test is completed. In this way, the lifting time is relatively long.

[0015] The water in the sewage pool can be treated by the purification device and then reused, or directly discharged.

[0016] The transverse limiting arrangement can avoid transverse swing of the water tank during lifting, so that the water tank keeps vertical during lifting.

[0017] When the reversible motor is a double-head shaft structure, the number of lifting wires and winding shafts is two, two winding shafts are connected to two rotating shafts on the two sides of the reversible motor, the lengths of the two lifting wires are equal, and one end of each lifting wire is connected to a winding shaft, and the other end is hung on two first adhesive hooks through a lifting ring arranged at the end.

[0018] As one of the specific implementation schemes, the water tank detection lifting and water changing structure of the non-continuous water source water supply further comprises a second adhesive hook and a limiting ring at the same height (i.e., the second adhesive hook and the limiting ring have the same height from the ground), the number of the second adhesive hook is two, the two second adhesive hooks are oppositely attached to the two sides of the water tank body, the limiting ring is attached to the outside of the water tank, and the hanging rings at the two ends of the transverse limiting belt are connected to the two second adhesive hooks after the transverse limiting belt passes through the limiting ring. The water tank can move up and down, but cannot swing transversely under the limitation of the transverse limiting belt, improving the stability of operation. With this scheme, the vertical position of the transverse limiting belt is basically unchanged when the water tank moves up and down, and the up and down displacement of the water tank is 2-5 cm, which can meet the activation and restart function. The two second adhesive hooks are oppositely attached to the middle height of the water tank, and the limiting ring is also attached to the same height on the water tank, i.e., the limiting belt is located at the middle height of the water tank, so that the water tank will not be separated from the transverse limiting belt during lifting, and the transverse swing will always be restricted.

[0019] The limiting ring adopts a structure similar to the adhesive hook, except that the hook structure is replaced by a ring structure. The transverse limiting belt passes through the limiting ring to avoid the transverse limiting belt moving up and down with the water tank. It also has a transverse restraining effect.

[0020] The transverse limiting belt does not affect the up and down movement of the water tank, but restricts the transverse swing of the water tank.

[0021] In order to improve the stability of detection, the lifting device of the water tank detection lifting and water changing structure of the non-continuous water source water supply further comprises a base, the base is arranged at the bottom of the support, the surface of the base is provided with a groove matched with the bottom of the water tank, and the water tank is arranged in the groove.

[0022] In order to ensure stability, the above-mentioned support includes a transverse square frame, four support columns and three connecting rods; the four support columns are respectively arranged at the bottom four corners of the transverse square frame; the three connecting rods are respectively connected together at the bottom left side, the back side and the right side of the four support columns; the reversible motor is installed on the transverse square frame, the water purifier is arranged at the bottom of the transverse square frame and located between the four support columns, the water tank is located directly below the winding shaft, and the distance between the transverse square frame and the top of the water tank is greater than 20 cm.

[0023] In order to facilitate use, the base can be pulled out from the bottom of the support. In this way, the disassembly and assembly of the water purifier are facilitated.

[0024] In order to ensure the stability of the water tank during lifting, the lifting wire is a metal rope.

[0025] In order to facilitate use, the highest water level and the lowest water level in the water tank are respectively provided with a highest water level sensor and a lowest water level sensor. When the lowest water level is sensed, the water needs to be replaced, and when the highest water level is sensed, the water needs to be stopped.

[0026] For the non-continuous water source water supply water purifier which needs to lift the water tank and then put it down to activate the washing function, as common sense, the water purifier includes a main body and a water tank arranged on one side of the main body. The water tank is taken off, water is added to the highest water level, and then the water tank is inserted back into the main body to activate the washing function and start water production. During the water production process, the waste water will flow back into the water tank, that is, the water in the water tank will become more turbid. When the lowest water level is reached, the water purifier will automatically stop water production and prompt to pour out the waste water in the water tank, replace the water in the water tank, and then reposition the water tank to activate the washing function and cycle water production. It should be noted that the structure of the water purifier itself is not improved in this application.

[0027] In order to facilitate the automatic control, the above-mentioned non-continuous water source water supply water purifier detects the lifting water replacement structure, and further includes a PLC controller, the reversible motor, the water pump, the electromagnetic valve, the highest water level sensor and the lowest water level sensor are connected with the PLC controller, and the reversible motor, the water pump and the electromagnetic valve are controlled by the PLC controller.

When the liquid level in the water tank reaches the lowest water level (sensed by the lowest water level sensor), the water purifier stops water production, the water pump is started to discharge the waste water in the water tank, the water pump is turned off after the water pumping is completed, and then the above-mentioned water production operation is repeated until the test is completed.

[0028] In order to improve the stability of pumping, the first end of the pumping pipe extending into the bottom of the water tank is provided with a counterweight, the bottom of the counterweight is provided with an arc-shaped through slot, and the end of the pumping pipe is clamped in the arc-shaped through slot. The end of the pumping pipe and the arc-shaped through slot can be bonded together or connected together by other means.

[0029] In order to improve the stability of the water changing pipe and the pumping pipe, the water changing pipe and the pumping pipe are respectively connected to the side wall of the water tank through elastic sleeves, and the elastic sleeves comprise a u-shaped clamp and a sleeve pipe; the u-shaped clamp is a u-shaped structure with an opening downward, and the size of the opening of the u-shaped clamp is adjustable; the sleeve pipe is connected to the side wall of the u-shaped clamp, and the sleeve pipe is located on the inner side of the water tank; the sleeve pipe is provided with a gap along the length direction, and the sleeve pipe is divided into a first half pipe and a second half pipe, and the size of the first half pipe and the second half pipe is adjustable; the inner side of the u-shaped clamp, the first half pipe and the second half pipe are all provided with a silica gel layer, so as to increase the friction and improve the stability; the opening of the u-shaped clamp is clamped downward on the top of the water tank, and the water changing pipe and the pumping pipe are wrapped in the corresponding sleeve pipes.
