Principle of work of the present invention:
1, during pressing nozzle button 3, overcome the elastic force of main spring 29, nozzle button 3 moves down, because of the elastic force effect of auxiliary spring 26, piston 25 and then moves down together, and the gas of pump chamber 21 inner chambers is compressed, when piston 225 withstands the first connecting portion 213 between the first pump district 211 and the second pump district 212, overcome auxiliary spring 26 elastic force, piston 25 is opened with lower pump rod 27 sealing positions, and pump chamber 21 inner chamber gases from then on position are discharged from; Lower pump rod 27 moves down into the second connecting portion 215 between 212 Yu Sanbeng districts 214, the second pump district, and nozzle button 3 stops pressing down;
While 2, unclamping nozzle button 3, because of the effect of main spring 29 and auxiliary spring 26, piston 25 resilience together with the rapid sealing also of lower pump rod 27, pump chamber 21 inner chambers form parital vacuums, under external atmosphere pressure effect, pump pearl 210 is introduced and washed open to liquid from liquid guiding tube 5 and enter inner chamber; Continue to press, thus because of liquid incompressibility by liquid by flow through nozzle 32 ejection of nozzle button 3 of upper pump rod 23.
