Description

Technical Field

[0001] The utility model relates to the technical field of axial flow water pumps, in particular to a waterproof axial flow water pump. Background Art

[0002] A water pump is a machine that transports liquids or pressurizes liquids. It transfers the mechanical energy of the prime mover or other external energy to the liquid to increase the energy of the liquid. It is mainly used to transport liquids including water, oil, acid and alkali liquids, emulsions, suspensions and liquid metals.

[0003] Since the liquid needs to circulate and the rotor has no through holes, the liquid at the bottom of the rotor pushes the rotor toward the pump head. When the water pump is used for a long time, it is easy for water to enter, which will cause damage to the circuit board. The machine will not work and cause losses. Therefore, it is necessary for us to design a waterproof axial flow water pump. Utility Model Content

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a waterproof axial flow water pump, comprising an inlet port, a pump casing, a water outlet port, a rotating shaft, a rotor, a first sealing ring, a second sealing ring, a bottom cover, a third sealing ring and a circuit board, a rotor is inserted in the middle of the pump casing, the output end of the rotor is rotatably connected with the rotating shaft, the upper end of the pump casing is inserted with a water inlet port, the bottom end of the pump casing is inserted with a water outlet port, the rotating shaft is arranged in the water inlet port cavity, a circuit board is installed at the bottom of the rotor, the bottom of the pump casing is shielded by the bottom cover to block the circuit board in the pump casing cavity, and the connection between the bottom cover and the pump casing is sealed by the third sealing ring.

[0006] Preferably, the sleeve joint between the pump housing and the water inlet port is sealed by a first sealing ring.

[0007] Preferably, the sleeve joint between the pump housing and the water outlet port is sealed by a second sealing ring.

[0008] Preferably, the water inlet port is locked and fixed to the pump housing by screws, and the water outlet port is locked and fixed to the pump housing by screws.

[0009] The beneficial effect of the utility model is that the circuit board can be effectively sealed and protected by the bottom cover and the third sealing ring arranged between the bottom cover and the pump housing to prevent water from entering and causing damage to the circuit board.
