Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Example 1

Referring to fig. 1 and 2, a first embodiment of the present utility model provides a novel electromagnetic water pump, which includes a sleeve 3, a connector 9, and a cylindrical tube 1 assembled inside a coil;

the cylinder tube 1 comprises a spring 11 and an iron core 12, the iron core 12 comprises a main shaft 121 and a piston shaft 122, and one end of the main shaft 121 is connected with the spring 11; the piston shaft 122 is provided with a damping rubber ring 10, and a gasket 2 with gasket overflow holes 21 on four sides is inserted into a piston cavity 31 of the sleeve 3 through a sealing ring C8 in the sleeve 3; a first one-way valve is arranged in the piston cavity 31; the first check valve comprises a first return spring 311 and a first sealing rubber head 312, the first check valve enables the first sealing rubber head 312 to seal a valve port on the piston shaft 122 of the iron core 12 through the pressure of the first return spring 311, fluid can enter the piston cavity 31 through the valve port of the iron core 12, and fluid in the piston cavity 31 cannot enter the cylinder tube 1 through the valve port of the iron core 12; the sleeve 3 is provided with a water inlet guide post 32, and the water inlet guide post 32 is connected with the water inlet pipe 6 through a sealing ring A4; the piston cavity 31 of the sleeve 3 is also provided with a water passing hole through the upper plane, and the water passing hole is connected with the water outlet pipe 5 of the connector 9 through a second check valve consisting of a second reset spring 71, a second sealing rubber head 72 and a sealing cushion block 73;

the sleeve 3 is connected with the cylinder tube 1 through a rubber ring in a sealing way, and the connector 9, the sleeve 3 and the cylinder tube 1 are fixed together through screws and coils.

Example 2

Referring to fig. 1-3, a second embodiment of the present utility model is based on the previous embodiment, except that:

the second one-way valve can be replaced by a duckbill one-way valve 7 shown in fig. 3, and the duckbill one-way valve 7 has the function of forward water passage and reverse water stop.

The working principle and the using flow of the utility model are as follows: such a water pump mainly works by up-and-down reciprocation of the iron core 12; when the iron core 12 moves downwards, the volume of the piston cavity 31 of the sleeve 3 increases, the internal pressure decreases and is smaller than the atmospheric pressure, and the second one-way valve is in a sealing state; since the external air pressure is communicated with the inside of the cylindrical tube 1, the atmospheric pressure is larger than the air pressure in the piston cavity 31 at this time; the air pressure opens the first one-way valve to enable fluid to enter the piston cavity 31 of the sleeve 3 through the through hole in the iron core 12, and the action of sucking the fluid is completed; when the iron core 12 moves upwards, the internal volume of the piston cavity 31 is reduced and the pressure is increased, at the moment, the first one-way valve is in a closed state, the increased pressure in the piston cavity 31 is larger than the atmospheric pressure, and the second one-way valve is opened, so that the fluid is discharged through the water outlet pipe 5 by the second one-way valve, the action of discharging the fluid is completed, and the water absorption and the water discharge of the water pump are completed by the reciprocating movement of the iron core 12;

as described above, after the fluid enters the water pump, the fluid must pass through the water inlet guide post 32 on the sleeve 3, the through hole formed by the side edge of the sleeve 3 and the cylindrical tube 1, and the water passing through the water passing hole on the side of the gasket 2 to reach the innermost part of the cylindrical tube 1, and the water entering the cylindrical tube 1 is discharged out of the pump through the through hole in the iron core 12 and the piston cavity 31 and the second one-way valve, so that the water inlet and outlet can also enable the fluid to pass through the inside of the pump body at the same end, and the heat dissipation effect can be achieved.

The position of the water inlet pipe 6 can be different according to the requirements, as shown in fig. 4 and 5.
