Body is gone upward at damping hole, and 1/10th of cross-sectional area less than link slot of damping hole avoid upper cavity and quick backflow extremely
Lower chamber.
The cross-sectional area of above-mentioned upper chamber bottom is greater than the cross-sectional area at the top of lower chambers.Upper and lower difference in areas is in pressure phase
With in the case where, the pressure of upper chamber bottom will lead to greater than the pressure at the top of lower chambers.Cause pump core during compression,
Due to the presence of damping hole, it is unable to the pressure of Fast-Balance upper and lower chambers, epicoele chamber pressure can be higher than rapidly the pressure of lower chambers.
The bottom chamber of above-mentioned pump core main body is provided with relief hole 20, and the lower semisection of lower chambers is provided with gas pressure relief slot 21.
Above-mentioned middle cover and pump core main body screw cooperate, and pump core main body is facilitated to be fixed on middle cover, and by middle cover and contain

To valve, under the action of the spring, reversed check valve is also closed.Pass through link slot and damping hole phase between upper cavity and lower chamber
It is logical, it fills out respectively hydraulically full.
Movement after pressure spraying pump head is divided into three processes:
First process is as shown in figure 4, when finger pressing nozzle head, connecting column compression downlink, the cone of the anti-plunger of piston upper end
Part and the rotary table part of connecting column are in contact, and the pressure of upper chamber and lower chambers is smaller at this time, connecting column band piston
Downlink, while the volume of upper chamber and lower chambers is compressed, pressure is greater than the elastic force of spring at this time, and spring starts to tighten, and pushes down steel
Pearl closes the check valve of lower chambers bottom, and lower chambers will not pressure release.
Second process is as shown in figure 5, as finger continues pressing nozzle, and connecting column continues traveling downwardly, the indoor pressure of epicoele
It gradually increases, since the diameter of the bottom of upper chamber is greater than at the top of lower chambers, the indoor rate of pressure increase of epicoele compares cavity of resorption
Room is fast, and due to the presence of damping hole, the indoor pressure of epicoele cannot be transmitted to lower chambers rapidly, causes the indoor pressure of epicoele big
In lower chambers, spring is further compressed, and anti-plunger downstream rate is faster than upper piston downstream rate.It is indoor anti-to cause epicoele
The cone of plunger is separated with the round table surface of upper piston, i.e., reversed check valve is opened, and upper chamber is connected to nozzle head, and highly pressurised liquid is fast
Speed generates atomizing effect by nozzle head pressure release.
Third process is as shown in fig. 6, when finger further depresses nozzle, and the indoor highly pressurised liquid of epicoele is rapidly from reversed list
It is released to valve；When the pressure of epicoele chamber pressure and lower chambers is close to when balancing, spring is counter to piston to be pushed away, and moves up piston, reversely
Check valve uplink closes upper chamber's top exit.Anti- plunger continues traveling downwardly, and the piston of anti-plunger drops to letting out for pump core main body
Indent is hereinafter, the intracorporal fluid pressure of cavity of resorption passes through rapidly the gap of anti-plunger piston exterior, arrival pump core main body from gas pressure relief slot
Relief hole restore the pressure of lower chamber from relief hole pressure release.
After finger unclamps nozzle head, spring pushes anti-plunger and upper piston uplink, lower chamber and upper cavity negative pressure occur,
The check valve of lower chambers bottom is opened, and the lower chamber of pump core sucks liquid.During anti-plunger uplink, gas pressure relief slot is closed.On
By being restored to the state of Fig. 3 after link slot and damping hole is also filled out hydraulically full in cavity.
Advantages of the present invention is embodied in three aspects, first is that the volume of upper cavity is increased, by between upper and lower cavities
Damping hole design sprays the intracorporal liquid of epicoele when high speed is sprayed, and the liquid of lower chamber will not quickly enter upper cavity, because
This not will cause upper cavity pressure rise excessive velocities, cause secondary spraying.
Second is that increasing the pressure relief of lower chamber, designed by gas pressure relief slot and relief hole, permission is gone downwards to most in nozzle
When big stroke, extra highly pressurised liquid is discharged by relief hole in lower chamber, reduces the pressure of lower chamber.Avoid lower chamber
When pressure is higher, the check valve of inlet is not easy to open.It is more smooth when pump core sucks liquid by suction pipe.
Third is that being communicated between upper cavity and lower chamber by damping hole, the intracorporal liquid of cavity of resorption slowly flows into upper cavity, keeps away
It is too fast to exempt from pressure rise in upper cavity, reversed check valve is caused to be opened, it is it is possible to prevente effectively from jet hole spilling water and infiltration phenomenon.
Therefore the present invention is that a kind of stability is preferable, and the uniform spraying pump head structure of atomisation pressure can be widely used and be in
It occupies, medical treatment, cosmetic field.
