[0015] In order to clearly illustrate the scheme in the utility model, preferred embodiments are given below and described in detail with reference to the accompanying drawings. The following description is essentially only exemplary and is not intended to limit the application or use of the present disclosure. It should be understood that in all the drawings, corresponding reference numerals represent the same or corresponding parts and features.

[0016] like Figures 1 to 3As shown, the utility model provides a detachable electric spray gun, including a body 1, a gun head 2 connected to the body 1 and a grip 3 connected to the body 1, the body 1 includes a shell 11 and a motor assembly 12 installed at the rear of the shell 11, the rear end of the gun head 2 is provided with a plug-in column 21, the front end of the body 1 is provided with a plug-in hole 13, the plug-in column 21 is inserted into the plug-in hole 13, the outer wall of the plug-in column 21 is provided with a plurality of positioning ribs 22, the inner wall of the plug-in hole 13 is provided with a plurality of limiting grooves 14, the positioning ribs 22 are inserted into the limiting grooves 14. The motor assembly 12 in the utility model includes a motor and an airflow generating device driven by the motor, such as a fan. Thereby, the motor assembly 12 can generate a high-pressure airflow, which flows into the atomization structure in the gun head to atomize materials such as paint. The motor assembly, the gun head and the atomization structure can all adopt mature products in the market. The body 1 in the utility model is also connected to a storage tank 4, which stores materials that need to be atomized. The grip 3 is provided with an operating mechanism such as a trigger, and is also connected to a power cord or installed with a lithium battery. The main improvement of the utility model is that a plurality of positioning ribs 22 are provided on the outer wall of the plug-in column 21, and a plurality of limiting grooves 14 are provided on the inner wall of the plug-in hole 13, and the positioning ribs 22 are inserted into the limiting grooves 14. After the gun head 2 in the prior art is connected to the body 1, due to the short connection part between the plug-in column 21 and the plug-in hole 13, it is easy to shake up and down, left and right, and it is also easy to fall off. The utility model adds the connection structure of the positioning rib 22 and the limiting groove 14, and realizes a double connection structure, that is, on the basis of the connection and cooperation between the plug-in column 21 and the plug-in hole 13, the connection structure of the positioning rib 22 and the limiting groove 14 is added. Not only will the gun head be limited, but it can also ensure that the gun head will not shake up and down, left and right, and improve the stability of the connection between the gun head 2 and the body 1.

[0017] See also Figures 1 to 3 In the above embodiment of the utility model, it further includes that the front end of the body 1 is formed with a plurality of forwardly protruding ears 15, and the ears 15 are closely attached to the plug-in column 21. In this embodiment, there are two ears 15, which are respectively located on the left and right sides. The ears 15 can hold the plug-in column 21, reduce the left and right shaking of the gun head 2, and improve the stability of the connection. The whole of the ear 15 is arc-shaped, and its curvature is consistent with the outer wall of the plug-in column 21, so the ear 15 can hold the plug-in column 21 tightly.

[0018] See also Figures 1 to 3In the above embodiment of the utility model, it further includes that a material pot joint 23 is provided in the middle of the gun head 2, a support portion 24 is provided on the material pot joint 23, and a support member 31 is provided on the handle 3, and the support member 31 is connected to the support portion 24. The material pot joint 23 is connected to the material storage tank 4. Since the material storage tank 4 has a large weight, the gun head 2 is subjected to a large downward gravity. The matching structure of the support member 31 and the support portion 24 increases the support points and reduces the influence of the uneven force on the connection matching structure of the gun head 2 to the plug column 21 and the plug hole 13.

[0019] See also Figures 1 to 3 In the above embodiment of the utility model, the support portion 24 is further provided with a notch 25, the support member 31 is provided with a plug 32, and the plug 32 is inserted into the notch 25. The above structure is not only more stable in connection, but also more convenient for assembly and disassembly.

[0020] See also Figures 1 to 3 In the above embodiment of the utility model, a limiting groove 16 is further formed on the inner wall of the ear guard 15, and the limiting groove 16 is connected to the limiting groove 14. Thus, the connection and matching length of the positioning rib 22 is increased, and the stability of the gun head 2 and the body 1 is further improved.

[0021] See also Figures 1 to 3 In the above embodiment of the utility model, a card block 26 is further formed on the outer wall of the plug-in column 21, and a card interface 17 is provided in the plug-in hole 13, and the card block 26 is inserted into the card interface 17. The card block 26 and the card interface 17 play a locking role, so that the machine body 1 and the gun head 2 can be quickly disassembled and assembled.

[0022] In summary, the above contents are only embodiments of the present invention, which are only used to illustrate the principle of the present invention, and are not used to limit the protection scope of the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
