Description
Technical field
It the utility model is related to micro pump, more particularly to eccentric wheel reinforced structure.
Background technology
The micro pump of diaphragm type, it is to provide circular motion by motor, then makes the barrier film inside water pump by mechanical device
（Iris-diaphragm has a lot）Reciprocating is done, so as to compress, stretch the air in pump chamber, under check valve sheet effect, is being gone out
Pressure differential is produced between the mouth of a river or water inlet and external atmosphere pressure, in the presence of pressure differential, hydraulic pressure is entered into water inlet, then from water outlet
Mouth discharge.This micro pump is well used in occasions such as small household appliances, medicine equipments, but existing micro pump
The general accurate adjustment for being difficult to reach flow.
Although flow control of the existing dealer to water pump is studied, develop a kind of flow accurately control it is miniature
Water pump, including upper lid, valve seat, water pocket seat, base housing, water pocket, curved bar, drive shaft, eccentric wheel, motor and output circuit plate；
Motor is arranged on base housing, and the motor shaft of motor directly connects after stretching into base housing with the eccentric wheel in base housing,
Eccentric wheel is connected by drive shaft with curved bar, and water pocket is outwards installed in curved bar upper end on radial support, and water pocket is arranged on water pocket
On seat, water pocket seat is sealingly mounted on base housing, and valve base sealing is arranged on water pocket seat, and each water pocket is corresponded on valve seat and is opened up
Inlet opening and apopore, inlet opening and apopore install check valve respectively；Upper lid is sealingly mounted on valve seat, and upper cap-shaped is into water outlet
Interface and water inlet interface, water inlet interface connect with each inlet opening, and water outlet mouthpiece connects with each apopore.During pump working, motor
Band movable eccentric wheel is transmitted in curved bar by drive shaft again, then drives water pocket to realize Inlet and outlet water.Further, eccentric wheel or motor
The radial direction of axle corresponds to optoelectronic switch and coordinated formed with photoelectricity shielding plate, photoelectricity shielding plate and optoelectronic switch to detect motor speed,
Optoelectronic switch and the electrical connection of output circuit plate, output circuit plate is used for and external motor controller electrically connects and believes motor speed
Breath is sent to external motor controller；While pump working, the rotating speed of motor is detected by optoelectronic switch, output circuit plate will
The rotating speed sends the electric machine controller to outside, in order to which electric machine controller is accurately controlled the rotating speed of motor, so as to obtain not
Same amount and the stationary flow amount under different back pressures.
But in actual production and application, dealer has found：Only there is central shaft hole and bias on existing eccentric wheel
Hole, shrink situation be present in eccentric wheel forming process, cause eccentric wheel central shaft hole and eccentric orfice size it is unstable, with drive
Moving axis coordinates inaccuracy, and motion has some setbacks, and reduces the water pump life-span.
Utility model content
The purpose of this utility model is to provide a kind of micro pump eccentric wheel reinforced structure, to ensure the smooth of motion,
Improve the water pump life-span.
To achieve these goals, the technical solution of the utility model is as follows：
A kind of micro pump eccentric wheel reinforced structure, there is central shaft hole and eccentric orfice on eccentric wheel, also have on eccentric wheel
There are some grooves, some grooves are uniformly distributed to form a circle around central shaft hole.
There are four grooves, four grooves are on same circle with eccentric orfice, and eccentric orfice is located therein on the eccentric wheel
Between two grooves.
The side of the eccentric wheel is formed radially photoelectricity shielding plate.
After such scheme, the utility model adds some recessed because having done particular design to the structure of eccentric wheel
Groove escapes meat design, it is possible to reduce and the shrink in forming process is possible, meanwhile, this groove can coordinate for the thimble of the demoulding, side
Just machine-shaping, ensure the central shaft hole of eccentric wheel and the dimensionally stable of eccentric orfice, it is coordinated more with motor shaft and drive shaft
Accurately, it is final to ensure the smooth of motion, and realize that in light weight, balance is good, improve service life.
