Abstract
A water pump comprises a housing, a solenoid coil equipped inside the housing and a jet pipe attracted by the solenoid coil and capable of repeated motion. The jet pipe has a suction inlet larger than the jet pipe ejection outlet. The free-falling velocity of the water inside the jet pipe is lower than the jet pipe velocity. The accumulative amount of the water inside the jet pipe gradually increases and the pressure also increases to make the water sprayed out of the jet pipe. The water pump with no impeller equipped inside the housing thus has reduced easy-to-wear parts and a simple structure.
Description
Technical field
The utility model relates to a kind of liquid pumping machinery, specifically a kind of micro pump.
Background technique
Impeller type accounts for the overwhelming majority in the existing water pump, the pump of these two kinds of forms, and part easy to wear is many in pump case, complex structure.
The model utility content
In order to solve the many and baroque deficiency of existing water pump part easy to wear in pump case, the utility model provides a kind of water pump, and parts easy to wear such as impeller are not set in the housing of this water pump, and is simple in structure.
The utility model solves the technical measures that its technical problem takes: housing is made cylindrical shape, and electromagnetic coil is set in housing, and tubular nozzles is installed in the coil.The upper end of jet pipe dwindles into spout gradually, the lower end of jet pipe enlarges gradually, and as suction port, suction port is cut into angle, jet pipe top is established one and is gone up ring washer, a following ring washer is established in the bottom, the damping spring of packing between the housing upper end of last ring washer and electromagnetic coil, the thrust spring of packing between following ring washer and the electromagnetic coil housing lower end, the lower end of housing is the suction side of jet pipe just, connect filter screen, the upper end of housing, just the upper end of jet pipe connects output tube.When electromagnetic coil was switched on, the magnetic field suction jet pipe that coil produced moved upward, and when electromagnetic coil cuts off the power supply, lost magnetic force, and jet pipe moves downward under the effect of thrust spring.During use, the housing lower end of water pump is immersed in the water, jet pipe is under the order of the power on/off that electromagnetic coil sets in advance, constantly reciprocating up and down, because jet pipe is up-small and down-big, again because the speed that the speed of water free fall in jet pipe moves up and down less than jet pipe, the amount of savings of water in jet pipe increases, pressure also increases gradually, and water is just discharged from nozzle hole, thereby reaches the purpose of energy pumps water under the structure that impeller is not set in the pump.
The beneficial effects of the utility model are that part easy to wear is few, simple in structure in the pump.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Among the figure: 1. housing, 2. electromagnetic coil, 3. jet pipe, 4. thrust spring 5. descends ring washer, 6. suction port, 7. ring washer on the filter screen 8., 9. spring, 10. spout, 11. outlet pipes, 12. power lines.
Embodiment
In the drawings, housing (1) is made cylindric, electromagnetic coil (2) is set in housing, peace tube shape jet pipe (3) in the coil, the jet pipe upper end shortens spout (10) gradually into, the lower end of jet pipe is expanded into trumpet-shaped suction port (6), suction port is cut into angle, ring washer (8) is established on jet pipe top, ring washer (5) is set in the bottom of jet pipe, mounting spring (9) between last ring washer 8 and the electromagnetic coil upper end housing, its effect is the bump of ring washer (8) and electromagnetic coil housing when avoiding jet pipe descending, installs to promote spring (4) connection filter screen (7) in housing lower end between following ring washer (5) and the electromagnetic coil housing lower end, the upper end of housing connects outlet pipe (11), and power line (12) passes housing and is connected with electromagnetic coil.
Claims (2)
1. water pump, housing is made cylindric, electromagnetic coil is set in housing, it is characterized in that: in described electromagnetic coil, jet pipe is installed, the described jet pipe spout that dwindles into gradually suitable for reading, the lower end of jet pipe enlarges gradually as suction port, ring washer is established on jet pipe top, ring washer is set in the bottom of jet pipe, mounting spring between described upward ring washer and the electromagnetic coil housing upper end, installed thrust spring between described ring washer down and the electromagnetic coil housing lower end, the lower end of described housing connects filter screen, and the upper end of housing connects outlet pipe.
2. a kind of water pump according to claim 1 is characterized in that: the suction port of described jet pipe is cut into angle.
