It is made, ball sealer can be bead, steel ball etc..
By Fig. 1 into Fig. 6 for visual angle: when using the utility model, pressing trigger squeeze, reset spring compression, plate body with hand
Hydraulic fluid piston is driven to be inwardly compressed, ball sealer moves down, and lower compression elasticity back taper pipe is received, bullet to erect in seat pipe upper end with dynamic elasticity
Property perpendicular seat pipe lateral wall and cylinder siphunculus inner sidewall between sealing disappear, liquid can enter tapping channel from hydraulic fluid chamber at this time, and
It sprays to form " water mist " from spraying road.After trigger to be released, under action of reset spring, each structure resets.At " spraying ", if
The partition inside and outside liquid container cannot be carried out in time, then in the reseting procedure that trigger is pressed into after bottom, release, since partition is tied
Structure does not reset also completely, and extraneous a small amount of air can also be entered in liquid container by tapping channel, leads to a small amount of liquid in tapping channel
Body outflow, 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
In the present embodiment, after single " spraying ", in trigger reseting procedure, since the perpendicular seat pipe of elasticity inherently has elasticity,
So reset and partition can extremely quickly be realized, to avoid the occurrence of the above problem.
