[0016] To clearly illustrate the solutions in this utility model, preferred embodiments are given below in conjunction with the accompanying drawings for detailed description. The following description is merely exemplary and not intended to limit the application or use of this disclosure. It should be understood that throughout the drawings, corresponding reference numerals denote the same or corresponding parts and features.

[0017] like Figures 1 to 4As shown, this utility model provides a spray gun with a snap-fit ​​structure, including a gun body 1 and a nozzle assembly 2 disposed at the front end of the gun body 1. The nozzle assembly 2 includes a nozzle 21, a wind cap 22, and a positioning ring 23 mounted at the front end of the gun body 1. A magnetic attraction component is provided between the positioning ring 23 and the gun body 1. A snap-fit ​​structure 4 is also provided between the positioning ring 23 and the gun body 1. The snap-fit ​​structure 4 includes a snap-fit ​​groove 41 disposed on the positioning ring 23 and a snap-fit ​​block 42 disposed on the gun body 1. When the positioning ring 23 is attracted to the gun body 1, the snap-fit ​​block 42 snaps into the snap-fit ​​groove 41. In this utility model, the wind cap 22 and the positioning ring 23 are an integral structure, or they can be separate structures, mainly used as an airflow nozzle. The positioning ring 23 serves a connecting function. Traditional structures use threaded connections, which are inconvenient to disassemble. This utility model uses a magnetic connection, which is convenient to disassemble. However, under high air pressure, the positioning ring and wind cap are prone to detachment. To overcome the above problems, this utility model adds a snap-fit ​​structure 4, which provides axial blocking, preventing the wind cap 22 and positioning ring 23 from flying off under high-pressure impact, thus improving safety. At the same time, the snap-fit ​​structure 4 is easy to disassemble, facilitating the removal of the positioning ring 23 and wind cap 22.

[0018] See Figures 1 to 4 In the above embodiment of this utility model, the magnetic attraction component further includes a first magnetic ring 31 installed in the positioning ring 23 and a second magnetic ring 32 installed on the gun body 1, wherein the first magnetic ring 31 and the second magnetic ring 32 are attracted together. This embodiment uses two magnetic rings for connection; however, multiple magnetic blocks can also be used. Each magnetic ring has multiple magnetic poles for easy connection.

[0019] See Figures 1 to 4 In the above embodiment of this utility model, the snap-fit ​​groove 41 further includes a snap-fit ​​section 411 and a locking section 412. After the snap-fit ​​block 42 passes through the snap-fit ​​section 411, under the attraction force of the magnetic attraction component, the positioning ring 23 deflects, and the snap-fit ​​block 42 snaps into the locking section 412. In this embodiment, the snap-fit ​​groove 41 is generally L-shaped. When the snap-fit ​​section 411 is aligned with the snap-fit ​​block 42, the magnetic poles of the first magnetic ring 31 and the second magnetic ring 32 are offset by a certain distance. After the positioning ring 23 is released, the first magnetic ring 31 and the second magnetic ring 32 will deflect to align their magnetic poles, thereby causing the snap-fit ​​block 42 to snap into the locking section 412. At the same time, under the action of magnetic force, the snap-fit ​​block 42 will not detach from the locking section 412. The above structure is convenient to operate and safe and reliable.

[0020] See Figures 1 to 4In the above embodiment of this utility model, the locking block 42 is further disposed below the gun body 1, and the locking groove 41 is located below the positioning ring 23. The locking block 42 in this utility model is a limiting point protruding from the gun body, which is visible to the naked eye or, through design and assembly, not easily distinguishable to the naked eye. Figure 3 The positioning ring 23 shown is rotated 180 degrees to display the snap-fit ​​groove 41. In reality, the snap-fit ​​groove 41 is located below the positioning ring 23, corresponding to the position of the snap-fit ​​block 42. Placing the snap-fit ​​structure 4 at the bottom creates a hidden design that does not affect the overall appearance of the spray gun. Of course, the snap-fit ​​structure 4 can also be placed at the top.

[0021] See Figures 1 to 4 In the above embodiments provided by this utility model, the snap-fit ​​groove 41 is further comprising a square groove or a circular groove. The above structure is easy to manufacture and provides a better snap-fit ​​effect.

[0022] See Figures 1 to 4 In the above embodiments provided by this utility model, the snap-fit ​​structure is further comprising one or more. This embodiment uses one, but it could also include two or three.

[0023] In summary, the above description is merely an embodiment of this utility model and is only used to illustrate the principle of this utility model, not to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
