The specific embodiment
Below in conjunction with the drawings and specific embodiments, this case is described in further detail.
This case relates to a kind of foam/water gun-launcher head, as Figure 1-5, mainly comprises big gun head body 1 and foaming tube 2, and big gun head body 1 and foaming tube 2 connect with each other, and providing preferred embodiment this two is to establish connection by change neck tube 3 locks.
The free end of described big gun head body 1 is provided with inlet 11, and the free end of foaming tube 2 is provided with jet (in figure for indicating).On big gun head body 1, offer one time air entry 12.The place, one end being connected with big gun head body 1 on foaming tube 2 is provided with secondary suction mouth 21, and commutator segment 4 is also installed in foaming tube 2.
