Stability in the process or guarantee sealing locating effect.
In this implementation, cylinder body is divided into two cavitys by hydraulic fluid piston, wherein the cavity being connected to cylinder siphunculus is named as inner cavity,
Inner cavity, elasticity are erected in seat pipe, the space that adapter cavity collectively forms is named as hydraulic fluid chamber.Elastic ball seat can be by materials such as rubber
It is made, ball sealer can be bead, steel ball etc..
By taking visual angle in Fig. 1 to Fig. 6 as an example：When using the present invention, trigger squeeze, resetting spring compression are pressed with hand, plate body drives
Hydraulic fluid piston is inwardly compressed, and ball sealer moves down, lower compression elasticity back taper pipe, is received to be erected in seat pipe upper end with dynamic elasticity, and elasticity is perpendicular
Sealing between seat pipe lateral wall and cylinder siphunculus madial wall disappears, and liquid can enter tapping channel from hydraulic fluid chamber at this time, and from spray
Fog channel sprays to be formed " water mist ".After trigger to be released, under action of reset spring, each structure resets.At " spraying ", if cannot
The partition inside and outside liquid container is carried out in time, then in the reseting procedure that trigger is pressed into after bottom, release, also due to partition-type structures
It does not reset completely, extraneous a small amount of air can also be entered by tapping channel in liquid container, and a small amount of liquid flow in tapping channel is caused
Go out, at this time since pressure is not strong, the liquid of outflow would generally be in " drip shape ".This is apparently not what we were happy to see.And at this
In embodiment, after single " spraying ", in trigger reseting procedure, since the perpendicular seat pipe of elasticity inherently has elasticity, so
Reset and partition can be extremely quickly realized, to avoid the occurrence of the above problem.
