The operation principle of the present invention:
1, during pressing nozzle button 3, the elastic force of main spring 29, nozzle button 3 is overcome to move down,Because of the elastic force effect of auxiliary spring 26, piston 25 and then moves down together, the gas of pump chamber 21 inner chamberBody is compressed, when piston 25 withstands first between the first pump district 211 and the second pump district 212 evenDuring the portion 213 of connecing, auxiliary spring 26 elastic force, piston 25 is overcome to seal with lower pump rod 27Position is opened, and pump chamber 21 inner chamber gas will be discharged from this position；Lower pump rod 27 moves down intoThe second connecting portion 215 between two pump districts 212 and the 3rd pump district 214, nozzle button 3 stopsUnder press；
When 2, unclamping nozzle button 3, because of main spring 29 and the effect of auxiliary spring 26, piston25 seal rapidly with lower pump rod 27 and together with resilience, pump chamber 21 inner chamber forms parital vacuum,Under external atmosphere pressure effect, pump pearl 210 is introduced and washed open to liquid from liquid guiding tube 5 and entersInner chamber；Continue pressing, because of liquid Incoercibility thus by liquid by upper pump rod 23The nozzle 32 flowing through nozzle button 3 sprays.
The ultimate principle of the present invention and principal character and the present invention have more than been shown and describedAdvantage.Skilled person will appreciate that of the industry, the present invention is not restricted to the described embodiments,The principle that the present invention is simply described described in above-described embodiment and description, without departing from thisOn the premise of bright spirit and scope, the present invention also has various changes and modifications, these change andImprovement both falls within scope of the claimed invention.Claimed scope is by appendedClaims and equivalent thereof define.
