The specific embodiment

Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.

The invention provides a kind of podwer gun of built-in dust blowing system, as Fig. 1, Fig. 2 and shown in Figure 5, it comprises: rifle body 1, rifle body 1 are divided into right side part 1-1 and left part 1-2, rifle headstock 2 and rifle pin 4;

Described rifle body 1 also comprises: powder path 10, main inlet channel 11, first gas passage 14, second gas passage 15, first air valve seat 12, second air valve seat 13, first through hole 111, second through hole 121, third through-hole 131 and fourth hole 141;

Described first through hole 111 connects main inlet channel 11 and described first air valve seat 12, described second through hole connects described first air valve seat 12 and described second air valve seat 13, the right flank of described rifle body is provided with first gas passage 14, described third through-hole 131 connects the right flank of described second air valve seat 13 and described rifle body, and be communicated with described first gas passage 14, the left surface of described rifle body is provided with second gas passage 15, described fourth hole 141 connects rifle body left surface and right flank, and described second gas passage 15 is interconnected with described first gas passage 14 by described fourth hole 141;
