Safety interlink assembly of liquid agent ejection device

Abstract

A safety interlink assembly of a liquid agent ejection device has a receiving chamber and a seat. An elastic body with a liquid agent is installed in the receiving chamber. The seat has an impact unit limited by a safety interlink assembly with two stage movements. The safety interlink assembly has a safety key installed on the top of the receiving chamber, a slidable rod limited by the safety key and a linking rod connected to the safety interlink assembly, and a bolt. The bolt buckles the impact unit and changes a position thereof by which the slidable rod moves backwards to drive the linking rod. The stress of the spring at the back end of the impact unit pushes forwards to impact the elastic body so that the liquid agent of the elastic body is sprayed out strongly from the receiving chamber.

1 . A safety interlink assembly of a liquid agent ejection device comprising:
 a receiving chamber having an elastic body of a liquid agent; a seat having an impact unit;   wherein the impact unit is limited by the safety interlink assembly; and the safety interlink assembly comprising:   a safety key being installed on a top of the receiving chamber;   a tenon and an elastic unit under the safety key;   a slidable rod being installed on a top of the receiving chamber;   the slidable rod having a buckled end and interlinking to a linking rod;   an inclined groove at the back end of the linking rod;   a bolt being installed in the inclined groove;   wherein the tenon is limited and buckled to the slidable rod; and the impact unit is buckled limitedly because the inclined groove of the linking rod fixes the bolt so that the bolt will confine the movement of the impact unit.   
   
   
       2 . The safety interlink assembly of a liquid agent ejection device as claimed in  claim 1 , wherein a teethed cambered surface is installed above the buckled end. 
   
   
       3 . The safety interlink assembly of a liquid agent ejection device as claimed in  claim 1 , wherein each lateral side of the liquid agent ejection device has a rib and a combination groove. 
   
   
       4 . The safety interlink assembly of a liquid agent ejection device as claimed in  claim 1 , wherein the seat has a spring; the stress of the spring is applied to the impact unit so as to the impact unit is pushed forwards to generate a fast impact force. 
   
   
       5 . The safety interlink assembly of a liquid agent ejection device as claimed in  claim 1 , wherein the receiving chamber has a pad; and the pad is capable of preventing the liquid agent from permeating the receiving chamber while the liquid agent impacted by the impact unit is sprayed out strongly. 
   
   
       6 . The safety interlink assembly of a liquid agent ejection device as claimed in  claim 1 , wherein the receiving chamber has a receiving groove; and the receiving groove serves to prevent from leakage outwards when the liquid agent impacted by impact unit is sprayed out strongly.
