[0016] Please see Figure 1-3This utility model provides a polyurea coating spray gun with a filtering function, including a gun body 1, a filter screen 2, and a fixing mechanism 3. A material block 11 is provided at the front end of the gun body 1, and an inlet 12 is provided at one end of the material block 11. The liquid material enters the material block 11 through the inlet 12. The material block 11 has an inlet channel, and the liquid material enters the front and back of the gun body along the inlet channel before being sprayed out. An installation port 13 is provided on one side of the material block 11, which communicates with the inlet channel. The filter screen 2 is inserted into the material block 11 along the installation port 13, and the filter screen 2 can filter the liquid material. An installation block 21 adapted to the installation port 13 is fixedly connected to one end of the filter screen 2. A limiting groove 22 is provided on the outer side of the installation block 21. The fixing mechanism 3 is provided on one side of the installation port 13. The fixing mechanism 3 includes a fixing frame 31 fixedly connected to the surface of the material block 11. A slider 32 is slidably connected inside the fixing frame 31. A limiting block 33 is fixedly connected to one side of the slider 32, and the other side of the slider 32... A spring 34 is abutting against the filter screen 2. A crossbar 35 is fixedly connected inside the fixed frame 31. Both the slider 32 and the spring 34 are movably sleeved on the crossbar 35. A groove 36 is provided on the surface of the slider 32. With the setting of the fixing mechanism 3, when installing the filter screen 2, the slider 32 can be moved by a finger to slide along the crossbar 35, so that the slider 32 drives the limiting block 33 to slide into the fixed frame 31. Then, the filter screen 2 is inserted into the material block 11 through the installation port 13. After the installation block 21 is fully inserted into the fixed frame 31, the filter screen 2 is inserted into the material block 11. After the mounting port 13 is installed, the finger can be released, allowing the spring 34 to push the slider 32 to slide along the crossbar 35. This causes the slider 32 to slide the limiting block 33 into the limiting groove 22, thus limiting the mounting block 21 and fixing the filter screen 2. When removing the filter screen 2, simply use your finger to slide the slider 32 along the crossbar 35, causing the slider 32 to slide the limiting block 33 out of the limiting groove 22.
