[0002] A water pump is a device with one inlet and one outlet nozzle, and a vacuum or negative pressure at the inlet and a slight positive pressure at the outlet.

[0003] Currently, Chinese patent publication number CN210738840U, published on June 12, 2020, discloses a water pump, including a pump body, a pump outlet pipe, and a pump inlet pipe. The pump inlet pipe is connected to the inlet of the pump body, and the pump outlet pipe is connected to the outlet of the pump body. Before starting the water pump, the gas inside the pump body and in front of its inlet is vented. After starting, the liquid is drawn in through the pump inlet pipe and then discharged through the pump outlet pipe. The pump also includes an exhaust port pipe and an exhaust port pipe valve. The exhaust port pipe is connected to the pump outlet pipe and is close to the outlet of the pump body. The exhaust port pipe valve is installed on the exhaust port pipe.

[0004] This type of water pump uses a pump outlet pipe and a pump inlet pipe for water intake and discharge operations. In the existing technology, the motor in the pump body is powered in two ways: one is to directly connect to the city power grid using a power cord, and the other is to directly power the motor using a battery pack. However, in the existing battery pack power supply method, there is usually only one battery pack, so the battery life is relatively poor during use, which can easily affect the normal operation of the water pump. Utility Model Content

[0005] The purpose of this invention is to provide a long-lasting water pump that is powered by dual battery packs to achieve long-lasting operation.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a long-endurance water pump, including a pump body, an outlet pipe located on one side of the pump body and an inlet pipe located on the other side of the pump body. Both sides of the pump body are provided with battery compartments with upper openings. Both sides of the battery compartments are provided with battery packs. A plug-in socket is provided on the inner wall of the battery compartment. A plug plate is provided on the side of the battery pack and embedded in the plug-in socket. Both sides of the plug-in socket are provided with slots for the side of the plug plate to be inserted. A flip cover is provided on the upper side of the battery compartment, which is rotatably connected to the battery compartment and is used to cover the battery pack.

[0007] A further feature of this invention is that a water-retaining ring is provided around the upper opening of the battery compartment, and a sealing ring for wrapping around the water-retaining ring is provided around the flip cover.

[0008] A further feature of this invention is that: two rotating sleeves are provided on one side of the flip cover, and a groove is provided on the side of the battery compartment for the two rotating sleeves to be inserted. Shaft grooves are provided on both inner walls of the grooves, and a connecting shaft with its end embedded in the shaft groove and passing through the two rotating sleeves is provided in the groove.

[0009] A further feature of this invention is that a reset torsion spring is sleeved in the middle of the connecting shaft, with one end connected to the flip cover and the other end connected to the inner wall of the opening groove.

[0010] A further feature of this invention is that: an opening groove is provided on the side of the flip cover away from the rotating sleeve, a latch is provided in the opening groove, shaft holes are provided on both sides of the latch, a protruding shaft passing through the shaft hole is provided on the inner wall of the opening groove, a movable locking hook is provided at one end of the latch, a fixed locking hook is provided on the outer wall of the battery compartment for the movable locking hook to engage, and a connecting spring is provided on the inner wall of the opening groove, with one end pressed against the opening groove and the other end pressed against the inner wall of the latch away from the movable locking hook.

[0011] A further feature of this invention is that a limiting groove is provided on the inner wall of the opening groove for embedding the end of the connecting spring.

[0012] A further feature of this invention is that the outer wall of the latch is provided with an anti-slip groove.

[0013] In summary, this utility model has the following beneficial effects:

[0014] 1. With battery compartments on both sides of the pump body, two battery packs can be stored in the two battery compartments. The battery packs are inserted into the connectors using insert plates, so as to achieve stable installation of the battery packs in the battery compartments. The battery packs are then wrapped with flip covers for protection. At this time, the pump body can be powered by the two battery packs, which ultimately helps to improve the pump body's endurance.

[0015] 2. By utilizing the water-retaining ring set around the upper opening of the battery compartment, and by using the sealing ring to wrap around the water-retaining ring when the cover is wrapped around the upper part of the battery compartment, the possibility of external water entering the battery compartment can be reduced, thus preventing water from entering the battery compartment and affecting the power supply of the battery pack.

[0016] 3. The flip cover is inserted into the groove using a rotating sleeve, and the end of the connecting shaft is inserted into the shaft groove and passes through the rotating sleeve. At this time, the flip cover can be rotated on the battery compartment.

[0017] 4. By connecting one end of the reset torsion spring to the flip cover and the other end to the inner wall of the opening slot, the elastic restoring force of the reset torsion spring can ensure that the flip cover can be stably wrapped around the battery pack, reducing the possibility of external water entering the battery compartment after the flip cover is automatically opened.

[0018] 5. When the flip cover needs to be wrapped around the battery pack, press the latch to swing the movable hook away from the opening slot, and the connecting spring is compressed until the flip cover is wrapped around the battery pack. Then release the latch, and the elastic restoring force of the connecting spring will drive the movable hook to swing towards the opening slot. The movable hook will then lock into the fixed hook on the outer wall of the battery compartment. This will further help to stably wrap the flip cover around the battery pack and further reduce the possibility of water entering the battery compartment after the flip cover automatically opens.

[0019] 6. By utilizing the limiting groove opened on the inner wall of the opening groove, the end of the connecting spring can be inserted into the limiting groove, thereby limiting the position of the connecting spring;

[0020] 7. The anti-slip grooves on the outer wall of the latch can provide an anti-slip function, which helps the hand to press the latch stably. Attached Figure Description
