[0005] The purpose and effect of the dual-motor switching water supply equipment of the utility model are achieved by the following specific technical means:

[0006] A dual-motor switching water supply equipment includes a mounting frame, a square water tank is fixedly provided on the top of the mounting frame; two groups of delivery pistons are fixedly provided on both sides of the top of the mounting frame, the two groups of delivery pistons are symmetrically installed, and the telescopic ends of the two groups of delivery pistons are fixedly provided with piston drive frames; two groups of control valves are fixedly provided on the bottom of the square water tank, and the control valves are of a four-way structure; discharge pipes are connected to the outside of the control valves; two groups of drive motors are fixed on both sides of the middle of the mounting frame, and the shaft ends of the drive motors are both transmission-connected to crankshafts, which slide in the piston drive frame.

By operating the opening and closing mode of the sub-control valve, you can choose to use natural water pressure to drain water, or use the drive motor to rotate the crankshaft, and the crankshaft drives the piston drive frame to reciprocate, so that the delivery pistons on both sides can expand and contract and change volume to produce the delivery function, actively discharge the water to the outside, and then realize the control of water use, which is convenient to control and provides energy-saving effects.

The water transportation function can be converted into an exhaust function, and water is replenished by pumping air.

[0016] The floating ring is set to provide a limited exhaust function. After the air passes through the exhaust hole and enters the exhaust pipe for discharge, the negative pressure draws water into the square water tank through the supplementary pipe. After the water level rises, the floating ring naturally floats up and closes the exhaust hole to avoid further pumping of water, ensuring that only air can be pumped out to prevent invalid circulation.

[0024] The following is a further detailed description of the embodiments of the present invention in conjunction with the accompanying drawings and examples.

[0025] Example 1:

[0026] As attached Figure 1 To the attached Figure 5 As shown:

[0027] The utility model provides a dual-motor switching water supply equipment, comprising a mounting frame 1, a square water tank 2 is fixedly arranged on the top of the mounting frame 1; two groups of delivery pistons 3 are fixedly arranged on both sides of the top of the mounting frame 1, the two groups of delivery pistons 3 are symmetrically installed, and the telescopic ends of the two groups of delivery pistons 3 are fixedly arranged with piston drive frames 301; two groups of control valves 4 are fixedly arranged on the bottom of the square water tank 2, and the control valves 4 are of a four-way structure; discharge pipes 5 are connected to the outside of the control valves 4; two groups of drive motors 6 are fixedly arranged on both sides of the middle of the mounting frame 1, and the shaft ends of the drive motors 6 are transmission-connected with crankshafts 601, and the crankshafts 601 slide in the piston drive frame 301.

[0028] Among them, the outside of the delivery piston 3 is connected to a one-way valve A302 and a one-way valve B303. A pipe is set outside the one-way valve A302 to connect to both sides of the discharge pipe 5; a pipe is set outside the one-way valve B303 to connect to both sides of the sub-control valve 4.

[0029] Among them, a sliding valve core 401 is slidingly provided in the middle of the sub-control valve 4, an electric cylinder 402 is fixedly provided at the bottom of the sub-control valve 4, the telescopic end of the electric cylinder 402 is connected to the sliding valve core 401, and the upper part of the sliding valve core 401 is a trapezoidal block structure.

[0030] Among them, two groups of solenoid valves A7 are connected to the bottom of the square water tank 2, and pipes are set at the bottom of the solenoid valve A7 to connect to the sub-control valve 4.

[0031] Among them, an exhaust pipe 9 is fixedly installed in the middle of the square water tank 2, and a solenoid valve B8 is connected to the bottom of the exhaust pipe 9. A three-way connection is set between the solenoid valve B8 and the lower ends of the two groups of solenoid valves A7. Two groups of one-way valves C10 are also connected in the connecting pipes of the solenoid valves A7 and the solenoid valves B8.

[0032] Among them, a limiter 901 is fixedly set on the upper outside of the exhaust pipe 9; an exhaust hole 902 is opened on the top side of the exhaust pipe 9; a top cover 903 is fixed on the top of the exhaust pipe 9; a floating ring 904 is slidably set on the upper outside of the exhaust pipe 9, and the floating ring 904 can cover the exhaust hole 902.

[0033] A supplementary pipe 11 is fixedly provided inside the square water tank 2 and passes through the lower end thereof, and a solenoid valve C12 is connected to the bottom of the supplementary pipe 11 .

[0034] like Figure 1-5 As shown, when water is used, the solenoid valve C12 is connected to the outside air and opened, then the solenoid valve B8 is closed and the solenoid valve A7 is opened. After the water passes through the solenoid valve B8 naturally due to pressure, it passes through the sub-control valve 4 and is naturally discharged from the discharge pipe 5; when the flow rate of natural drainage is insufficient to meet the demand, the electric cylinder 402 is started to lift the sliding valve core 401, so that the water cannot directly enter the discharge pipe 5. At this time, the delivery piston 3 is used to produce a delivery effect, and the water is actively discharged to the outside, thereby realizing the control of water use.

[0035] Example 2:

[0036] On the basis of Example 1, when water needs to be replenished, the water is stored in the square water tank 2, the solenoid valve C12 is connected to the water source, then the solenoid valve C12 and the solenoid valve B8 are opened, the solenoid valve A7 is closed, and the drive motor 6 is started to rotate the crankshaft 601, and the crankshaft 601 drives the piston drive frame 301 to reciprocate, so that the delivery pistons 3 on both sides are extended and retracted to produce a delivery function, and the air in the square water tank 2 is extracted through the exhaust pipe 9. After the air passes through the exhaust hole 902 and enters the exhaust pipe 9 and is discharged, the negative pressure sucks the water into the square water tank 2 through the replenishment pipe 11;

[0037] After the water level in the square water tank 2 rises, the floating ring 904 naturally floats up, closing the exhaust hole 902 to prevent further pumping of water.

[0038] The specific usage and function of this embodiment are as follows:

[0039] In the present invention, when in use, water is stored in the square water tank 2, the solenoid valve C12 is connected to the water source, then the solenoid valve C12 and the solenoid valve B8 are opened, the solenoid valve A7 is closed, the drive motor 6 is started to drive the crankshaft 601 to rotate, and the crankshaft 601 drives the piston drive frame 301 to reciprocate, so that the delivery pistons 3 on both sides are extended and retracted to produce a delivery function, and the air in the square water tank 2 is extracted through the suction pipe 9. After the air passes through the exhaust hole 902 and enters the suction pipe 9 and is discharged, the negative pressure sucks the water into the square water tank 2 through the replenishing pipe 11. After the water level rises, the float ring 904 naturally floats up, closing the exhaust hole 902 to prevent further water pumping;

[0040] When using water, connect the solenoid valve C12 to the outside air and open it, then close the solenoid valve B8 and open the solenoid valve A7. After the water is naturally pressured through the solenoid valve B8, it passes through the sub-control valve 4 and is naturally discharged from the discharge pipe 5. When the flow rate of natural drainage is insufficient to meet the demand, the electric cylinder 402 is activated to raise the sliding valve core 401, so that the water cannot directly enter the discharge pipe 5. At this time, the delivery piston 3 is used to produce a delivery effect, actively discharging the water to the outside, thereby achieving water control.

[0041] The two sets of drive motors 6 can be started as needed to control the conveying direction.
