In one embodiment of the invention, the blast cap is a cylindrical head which is obliquely cut off and sealed, the side surface of the head of the blast cap close to the tip is provided with the jet hole, and the head of the nozzle is sleeved in the tail of the blast cap.
In one embodiment of the invention, the nozzle is boss-shaped, and the lower part of the nozzle is hollowed into a liquid cavity; the head of the nozzle is raised upwards, a liquid spraying hole is formed in the nozzle and connected with the liquid cavity, and a gas spraying hole penetrating through the nozzle is formed in the side wall of the nozzle.
In an embodiment of the invention, the hood is installed in a fixed seat, a fifth driving motor is installed in the fixed seat, a gear is installed on an output shaft of the fifth driving motor, a hood installation hole is formed in the fixed seat and is positioned on the right side of the fifth driving motor, a sliding groove is processed in the hood installation hole, the edge of the tail part of the hood protrudes outwards and is clamped in the sliding groove, and a gear ring is processed on the outer wall of the hood and is meshed with the gear.
In one embodiment of the invention, a liquid inlet cavity is formed in the middle of the connecting cylinder, and a liquid inlet hole is formed in the side wall of the connecting cylinder and communicated with the liquid inlet cavity; an air inlet hole is formed in the side wall of the connecting cylinder, a circular groove, a first annular groove and a second annular groove are formed in the surface of the top of the connecting cylinder from inside to outside respectively, an air outlet hole communicated with the air inlet hole and the first annular groove is formed in the side wall of the connecting cylinder, and the first annular groove is in butt joint with the air injection hole; the circular groove is butted with the liquid cavity.
In one embodiment of the invention, the top of the spray needle is in a shuttle shape, the spray needle penetrates through the liquid inlet cavity, and the shuttle-shaped part of the top of the spray needle is positioned in the liquid cavity on the top surface of the connecting cylinder.
The invention has the beneficial effects that: the invention provides a spray gun which has the advantages of simple structure and low manufacturing cost, stable spraying of paint can be realized through matching of a nozzle and a spray needle, workers only need to open or close introduction of compressed gas, the operation is simple, stable spraying of the paint can be realized, and the paint is favorably and uniformly sprayed on a workpiece.

Detailed Description
The invention is further described below with reference to the accompanying drawings.
Referring to fig. 1 to 3, the present invention provides a spray gun,
referring to fig. 1, in one embodiment of the present invention,
referring to fig. 1 to 2, in an embodiment of the present invention,
with reference to fig. 1, in an embodiment of the present invention, the wind cowl 1 is installed in a fixed base, a fifth driving motor 11 is installed in the fixed base 10, a gear 12 is installed on an output shaft of the fifth driving motor 11, a wind cowl installation hole is formed in the fixed base 10 and is located on the right side of the fifth driving motor 11, a sliding groove is processed in the wind cowl installation hole, a tail edge of the wind cowl protrudes outward and is clamped in the sliding groove, a front portion of the wind cowl penetrates through the wind cowl installation hole, a gear ring is processed on an outer wall of the wind cowl and is engaged with the gear, the motor drives the gear to rotate, so as to drive the wind cowl to rotate, so as to achieve spraying at different angles, and when a worker is at a position where it is difficult to rotate the spraying gun through a wrist and align the spraying at an appropriate angle, alignment can be achieved by rotation of the wind.
