Specific embodiment
Electromagnetic type diaphragm jet-pump as shown in Figure 1, including jet flow chamber 9, and the cavity 5 fixed with jet flow chamber 9, and install
The seat of honour 3 above cavity 5；Solenoid 1 is fixed in the seat of honour 3, and stator core 2 is spun in the seat of honour 3 by screw thread, and is located
In the center of solenoid 1；Driving spring 4 is placed in the inside groove 31 at the seat of honour 3, and its one end is crowded with the inner face 32 at the seat of honour 3
Pressure, the other end are extruded with the upper surface 61 of mover push rod 6；The mover push rod 6 is placed in the inside groove 51 of cavity 5；It is oriented to
Post 8 is fixed in cavity 5, and which is made up of high-abrasive material, and the motion to mover push rod 6 play the guiding role；The cavity 5 and spray
Stream is provided with diaphragm 11 between chamber 9, is provided with the second sealing ring 10 below the diaphragm 11 on jet flow chamber 9；The mover is pushed away
Bar 6 is provided with the first sealing ring 7 with 5 inwall of cavity；Inflow hole 901, liquid storage cylinder 902, spurt hole are provided with the jet flow chamber 9
904 and diaphragm mounting groove 903；Described inflow hole 901 and spurt hole 904 are made up of expansion/contraction end respectively, wherein inflow hole
901 serrated end is connected with liquid storage cylinder 902, and the expansion end of spurt hole 904 is connected with liquid storage cylinder 902；Described 2 He of stator core
Mover push rod 6 is permeability magnetic material.Liquid storage cylinder 902 is constituted a closed chamber by the second sealing ring 10 and diaphragm 11.When diaphragm to
During lower extruding, the liquid in liquid storage cylinder 902 is outwards sprayed by spurt hole 904；When diaphragm 11 is recovered upwards by extruding form, outward
The liquid on boundary is entered from inflow hole 901 to stream in liquid storage cylinder 902.
The course of work of electromagnetic type diaphragm jet-pump of the present utility model：In normality, apply the cycle on solenoid 1
Square-wave voltage Von, the generation of solenoid 1 magnetic field can produce electromagnetic force by stator core 2, be lifted up mover push rod 6, drive
Spring 4 of moving is in confined state, and diaphragm 11 is in and treats working condition, as shown in Figure 1.As shown in figure 3, when square-wave voltage is 0
When, mover push rod 6 moves downward and extrudes diaphragm 11 under the driving of driving spring 4, the mover push rod 6 with initial velocity
Clash into diaphragm 11 and move downward with dynamic diaphragm 11 and extrude the liquid in liquid storage cylinder 902 together, so that in liquid storage cylinder 902
Liquid outwards spray from spurt hole 904 under the extruding of diaphragm 11.Until the lower surface 62 of mover push rod 6 fits to cavity 5
Inner face 52 when stop motion, so far complete a jet flow operation.Hereafter, solenoid 1 receives square-wave signal voltage
VonWhen, stator core 2 can produce electromagnetic force, be lifted up mover push rod 6, and diaphragm 11 is returned in the presence of its own resilient
