AI Technical Summary
Technical Problem
The existing sandblasting guns have low abrasive flow rates and poor mixing uniformity, resulting in unsatisfactory surface treatment effects.
Method used
The air intake assembly, sand inlet assembly, and ejection assembly are designed with specific structures to ensure that the ejection channel and the airflow channel are aligned in a straight line. The sand inlet pipe is located on the side of the outer casing, and the sand is fully mixed within the containment space, thereby improving the uniformity of sandblasting.
Benefits of technology
It improves the uniformity of sandblasting and enhances the surface treatment effect.

Abstract
The utility model relates to a sand blasting gun which comprises an air inlet assembly, the air inlet assembly comprises a straight pipe, an air pipe joint formed at the outer end of the straight pipe, a conical head formed at the inner end of the straight pipe, and a ventilation flow channel which is formed in the straight pipe and extends to penetrate through the air pipe joint and the conical head; a sand feeding assembly, the sand inlet assembly comprises a shell sleeve, a switching sleeve and a sand inlet pipe, wherein the shell sleeve is arranged outside the straight pipe in a sleeving mode, and a containing space is formed by the shell sleeve and the straight pipe; the switching sleeve is connected between the straight pipe and one end of the shell sleeve in a sleeving mode; the sand inlet pipe is formed on the outer wall of the shell sleeve; the sand inlet joint is formed at the outer end of the sand inlet pipe; the sand inlet runner is formed in the sand inlet pipe and the sand inlet joint and is communicated with the accommodating space; and a spraying assembly. In this way, the fed sand can be fully mixed in the containing space and then sprayed out, so that the uniformity degree of sand blasting is improved, and the surface treatment effect is improved.
