Description
Technical field
It the utility model is related to the structure-improved of micro pump, more particularly to water pocket seat.
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：As shown in Figure 1-2, water supply capsule 31 is opened up on water pocket seat 3
The water pocket hole 32 of utricule installation and the deep gouge 33 of the edge installation of water supply capsule 31, deep gouge 33 is semi-enclosed structure, water pocket seat 3
The marginal existence part that top edge corresponds to water pocket 31 is not enclosed at grade region A, when water pocket 31 works, in high pressure phase, due to
High pressure effect can make water pocket 31 produce dilatancy and cause the edge of water pocket 31 not enclose and dug at grade region A, cause to seal
Failure, influences water pump normal work.
Utility model content
The purpose of this utility model is the water pocket seat structure-improved for providing a kind of micro pump, to prevent water capsule from deforming,
Ensure sealing, make water pump normal work.
To achieve these goals, the technical solution of the utility model is as follows：
A kind of water pocket seat structure-improved of micro pump, opened up on water pocket seat water supply capsule utricule installation water pocket hole and
The deep gouge of the edge installation of water supply capsule, the edge that water pocket is corresponded in the top edge of water pocket seat form raised enclosing, this enclosing
The enclosed slot of the edge installation of water supply capsule is cooperatively formed with deep gouge.
The outwardly thickening in edge that the water pocket seat corresponds to water pocket forms barricade, and gear coping forms enclosing.
After such scheme, the utility model coordinates to water because the top surface in water pocket seat adds enclosing with deep gouge
Capsule edge carries out Totally-enclosed protective, when water pocket is operated in high pressure phase, can prevent water pocket after water pocket high pressure dilatancy
Edge dig, ensure sealing validity, influence water pump normal work.
Brief description of the drawings
Fig. 1 is the sectional view that water pocket seat and water pocket coordinate in prior art water pump；
Fig. 2 is the structural representation of prior art water pocket seat；
Fig. 3 is structural representation of the present utility model；
Fig. 4 is the structural representation that the utility model and water pocket coordinate；
Fig. 5 is the sectional view that the utility model and water pocket coordinate.
Label declaration
Water pocket seat 3, water pocket 31, utricule 311, edge 312, water pocket hole 32, deep gouge 33, enclosing 34, barricade 35.
Embodiment
As in Figure 3-5, the utility model discloses a kind of water pocket seat structure-improved of micro pump, on water pocket seat 3
The utricule 311 for opening up the water supply capsule 31 of water pocket hole 32 is installed, and the edge 312 for also forming the water supply capsule 31 of deep gouge 33 is installed, in water pocket seat 3
Top edge correspond to the edge 312 of water pocket 31 and form the enclosing 34 of projection, this enclosing 34 and deep gouge 33 cooperatively form water supply capsule
The enclosed slot that 31 edge 312 is installed.In order to ensure the installing space at the edge 312 of water pocket 31, and ensure enclosing 34 to water pocket 31
The protective effect at edge 312, the outwardly thickening in edge 312 of the corresponding water pocket 31 of water pocket seat 3 form barricade 35, the top of barricade 35
Portion forms enclosing 34.
So, when water pocket 31 is operated in high pressure phase, enclosing 34 and deep gouge 33 coordinate to be played to the edge 312 of water pocket 31
Totally-enclosed protective, it can prevent the edge 312 of water pocket 31 after the high pressure dilatancy of water pocket 31 from being dug at A, ensure water pump
Validity is sealed, influences water pump normal work.
