Specific embodiment
This utility model is specifically described below by embodiment, embodiment is served only for carrying out this utility model
Further instruction, it is impossible to be interpreted as the restriction to this utility model protection domain, those skilled in the art is according to this practicality
Some nonessential modifications and adaptations that new content is made fall within the scope of this utility model protection.
With reference to Fig. 1, Fig. 2.
Self-priming air foam rifle, fire gun is cylindrical hollow configuration, and fire gun includes the spray for being arranged at front end
Mouthfuls 2, with spout 2 in same axis, the air intake 3 of rear end is set, for mixing between front end spout 2 and back air entrance 3
