[0021] Please refer to Figures 1 to 6 , the dust blowing gun main body structure design shell 3, motor cover 2, motor, air nozzle 1 and other components in the drawing, wherein mainly to motor cover 2, air nozzle 1 has been optimized design, other components can be made good corresponding design, the case through the optimization of structure, air nozzle 1 quick dismounting and installation, improve the anti-air leakage performance of whole dust blowing gun simultaneously.

[0022] The shell 3 in the drawing is formed by two shell parts mutually spliced, so that the motor cover 2 is fixed in the shell 3.

[0023] The motor cover 2 in the figure is designed with a front cover 21 and a tail cover 22, which can fix the motor and facilitate the fixing of the air nozzle 1. The front cover 21 is designed with a protruding part 211, an intermediate part 212 and an extension part 213. The protruding part 211 facilitates the mutual fixation with the air nozzle 1, the intermediate part 212 is used for the transition between the protruding part 211 and the extension part 213, and the extension part 213 is towards the tail cover 22. The overall inner diameter of the protruding part 211 is smaller than that of the intermediate part 212, so as to form an arrow shape. The protruding part 211 is designed with an inwardly recessed annular sealing groove 2213 structure at the end face position of the end part, a sealing ring is placed in the sealing groove 2213 to form a seal with the corresponding position of the air nozzle 1 to prevent air leakage. The protruding part 211 is designed with guide columns 2212 and clamping grooves 2211 arranged symmetrically at the side wall position. The clamping grooves 2211 are conventional structures for clamping the buckle 11, and the clamping grooves 2211 are arranged between the two guide columns 2212. The guide columns 2212 are long straight rods with a certain height. Through such design, the buckle 11 can be clamped into the clamping groove 2211, and the lead column can also be conveniently inserted into the guide groove 12. The extension part 213 extends outwardly, and its outer diameter is smaller than that of the intermediate part 212, so as to form a certain step structure, which facilitates the subsequent insertion of the extension part 213 into the extension groove 221 of the tail cover 22, thereby forming an inner sealing structure. In order to facilitate the installation of the wire, a plurality of wire passing holes 2131 can be designed on the extension part 213. The wire passing holes 2131 adopt an interference fit with the wire to avoid possible air leakage. Figure 6 As shown in FIG. 1, the tail cover 22 is also designed with a wire passing hole 2131 structure at the corresponding position, which is combined with the wire passing hole 2131 of the front cover 21 to press the wire tightly.

[0024] The air nozzle 1 in the figure adopts a structure similar to a sharp nozzle, and its inside is hollow to form an air outlet channel. The buckle 11 and the guide groove 12 structure are designed on the side wall of the tail part, so as to facilitate the quick installation and disassembly of the air nozzle 1 and the motor cover 2. Both components have two and adopt a symmetrical arrangement, and the two sides of the buckle 11 are the guide groove 12 structure. The buckle 11 is located at the end position of the air nozzle 1 towards the front cover 21, and the guide groove 12 penetrates the side wall of the air nozzle 1 as a whole. The cooperation of the guide groove 12 and the guide column 2212 ensures the accurate positioning of the air nozzle 1 and the front cover 21.

[0025] The motor in the figure is a conventional component, which is installed in the motor cover 2. The specific installation method can refer to the prior art.
