Description
Technical field
The utility model relates to a kind of water pump of washing machine extraction liquid detergent, is specifically related to a kind of hydrodynamic force gear pump.
Background technique
At present, on washing machine, mostly install for extracting the pump of the washing agent such as liquid detergent, emollients, be all to adopt the shortcomings such as motor drives, and its structure is larger, expensive, working life is shorter, caused very large trouble to our life.
Model utility content
Goal of the invention: in order to overcome the deficiencies in the prior art, the utility model provides a kind of hydrodynamic force gear pump, simple in structure, long service life, and also structural volume is little, is convenient to use in washing machine.
Technological scheme: for achieving the above object, a kind of hydrodynamic force gear pump of the present utility model, comprise frame structure and the drive mechanism that is positioned at frame structure, described frame structure comprises valve body, gear cavity, impeller cavity and the dividing plate between gear cavity and impeller cavity, described drive mechanism comprises impeller, driving wheel and follower, impeller is arranged in impeller cavity, driving wheel and follower are arranged in gear cavity, described valve body is provided with liquid entering hole and liquid outlet, between liquid entering hole and liquid outlet, be provided with successively seal ring, top board and solenoid valve one, between valve body and gear cavity, be provided with solenoid valve two, the break-make that described solenoid valve one control pump is got liquid, solenoid valve two is controlled the break-make of current.
As preferably, described solenoid valve one comprises electromagnetic coil, iron core and spring, is provided with iron core and spring in electromagnetic coil, and iron core one end is connected with top board, and the iron core the other end is connected with spring; When normality, due to spring force make top board tightly be adjacent to seal ring, liquid entering hole and liquid outlet are in not on-state, non-water flow enters impeller cavity; In the time that electromagnetic coil is switched on, iron core is because magnetic force is sucked back, and top board separates with seal ring, and liquid entering hole and liquid outlet are on state.
Beneficial effect: a kind of hydrodynamic force gear pump of the present utility model, by water-driven wheel rotation, thereby drive the rotation of driving wheel and follower, reach the object of extracting liquid, control the break-make of liquid entering hole and liquid outlet by solenoid valve one, simple in structure, long service life, and structural volume is little, is convenient to use in washing machine.
