[0002] With the continuous development of modern industrial and living needs, spray guns are used more and more widely in various fields, such as green plant maintenance, agricultural spraying, vehicle cleaning, etc. However, traditional spray guns often have some problems during use. These problems affect the performance and service life of the spray gun, prompting people to continuously improve and innovate the spray gun. In actual applications, the fluid handled by the spray gun often contains various impurities. If not filtered, these impurities can easily enter the inside of the spray gun, causing blockage or damage to the spray gun parts, resulting in frequent spray gun failures, which greatly shortens the service life of the spray gun. At the same time, during the use of the spray gun, the sprayed liquid is easily splashed onto the connection between the gun body and the nozzle, which will cause corrosion damage to the connection in the long run and accelerate the aging of the spray gun. In addition, the nozzle structure of the traditional spray gun is usually difficult to disassemble and install, which makes it very inconvenient for users to clean and maintain the nozzle. If the nozzle is not cleaned for a long time, it is easy to accumulate dirt, further aggravating the aging problem of the spray gun. Utility Model Content

The interior of the filter 12 is communicated with the interior of the spray gun body 11, and the interior of the water outlet 13 is communicated with the interior of the spray gun body 11. The sealing gasket 122 at the top of the filter 12 is threadedly connected to the spray gun body 11 through the threaded port at the top of the filter 12, so that the sealing gasket 122 contacts the inner wall of its bottom to ensure the sealing of the connection. There is a trigger on the spray gun body 11. Pressing the trigger on the spray gun body 11 can cooperate with the internal needle valve to move the valve core outward to open the flow channel. Conversely, releasing the trigger can close it.

[0023] The nozzle structure 2 includes an atomizing nozzle 21, the outer wall of the atomizing nozzle 21 is fixedly connected to a positioning rod 22, the side wall of the positioning rod 22 is symmetrically provided with a positioning groove 221, the outer wall of the positioning rod 22 is slidably connected to a sliding sleeve 23, the outer wall of the sliding sleeve 23 is fixedly connected to a tension spring 24, and the outer wall of the positioning rod 22 on one side of the atomizing nozzle 21 is fixedly connected to a sealing ring 25.

[0024] The interior of the positioning rod 22 is communicated with the interior of the atomizing nozzle 21, and the outer wall of the tension spring 24 away from the sliding sleeve 23 is fixedly connected to the outer wall of the atomizing nozzle 21. The sliding sleeve 23 can be slid along the positioning rod 22 by pulling, and the tension spring 24 is stretched to store force. The sliding sleeve 23 can be reset by releasing the tension spring 24.

[0025] The outer wall of the clamping block 16 is slidably connected to the inner wall of the positioning groove 221, the inner wall of the threaded sleeve 18 is threadedly connected to the outer wall of the atomizing nozzle 21, the outer wall of the water outlet 13 is in contact with the outer wall of the sealing ring 25, the outer wall of the clamping block 16 is in contact with the outer wall of the sliding sleeve 23, first turn the rubber soft cover 19 toward the direction of the spray gun body 11, as shown Figure 5 As shown, the threaded sleeve 18 is then rotated to move it along the outer wall of the atomizing nozzle 21 and the water outlet 13 toward the spray gun body 11, so that the threaded sleeve 18 is separated from the atomizing nozzle 21, and then the sliding sleeve 23 is pulled to slide along the positioning rod 22 toward the water outlet 13 and contact the inclined surface of the outer wall of the clamping block 16. At the same time, the tension spring 24 is stretched and stored. Then, the clamping block 16 is squeezed through the inclined surface on the clamping block 16, and slides outward along the clamping groove 14 through the sliding rod 15 and separates from the positioning groove 221, so that the nozzle structure 2 can be separated from the gun body structure 1. On the contrary, the atomizing nozzle 21 is positioned by the outer wall. The rod 22 is inserted into the water outlet 13 of the gun body structure 1, and the positioning rod 22 first contacts the clamping block 16. Similarly, through its inclined surface, the clamping block 16 slides outward along the clamping groove 14. At the same time, the extrusion spring 17 is compressed and stored. When the clamping block 16 slides to the same position as the positioning groove 221, the extrusion spring 17 releases the elastic force, and the clamping block 16 slides along the inner wall of the positioning groove 221 to be fixedly connected to the nozzle structure 2 and the gun body structure 1. Then the threaded sleeve 18 is threadedly connected to the outer wall of the water outlet 13 and the outer wall of the atomizing nozzle 21 to further enhance the stability of the connection. Then the rubber soft cover 19 is reset. Figure 1 shown.

[0026] Working principle: When the spray gun needs to be used, first connect the water pipe to the outer wall threaded port at the bottom of the filter 12. The fluid first enters the filter 12 in the gun body structure 1. The fluid passes through the filter screen 121 inside the filter 12. The filter screen 121 filters out impurities in the fluid to prevent impurities from entering the spray gun body 11 and causing blockage or damage to other components. The sealing gasket 122 on the top of the filter 12 is threadedly connected to the spray gun body 11 through the threaded port on the top of the filter 12, so that the sealing gasket 122 contacts the inner wall of its bottom to ensure the sealing of the connection and prevent fluid leakage.

[0027] Then the fluid passes through the water pipe inside the spray gun body 11, and the trigger on the spray gun body 11 is pressed to move the valve core in the needle valve outward, opening the flow channel, and the fluid enters the water outlet 13 above the spray gun body 11, and then is sprayed out from the atomizing nozzle 21 through the positioning rod 22. The rubber soft cover 19 on the threaded sleeve 18 threadedly connected to the atomizing nozzle 21, and at the same time cooperates with the threaded sleeve 18, can prevent the sprayed liquid from splashing onto the connection between the gun body structure 1 and the nozzle structure 2, thereby avoiding corrosion damage to the connection part. Otherwise, release the trigger to stop the water discharge.

[0028] When the nozzle structure 2 needs to be disassembled for cleaning and maintenance to avoid the nozzle from aging due to long-term cleaning, first turn the rubber soft cover 19 toward the direction of the spray gun body 11, as shown in FIG. Figure 5 As shown, the threaded sleeve 18 is then rotated to move it along the outer walls of the atomizing nozzle 21 and the water outlet 13 toward the spray gun body 11, so that the threaded sleeve 18 is separated from the atomizing nozzle 21, and then the sliding sleeve 23 is pulled to slide along the positioning rod 22 toward the water outlet 13 and contact the inclined surface of the outer wall of the clamping block 16. At the same time, the tension spring 24 is stretched and stored. Then, the clamping block 16 is squeezed through the inclined surface on the clamping block 16, and slides outward along the clamping groove 14 through the sliding rod 15 and separates from the positioning groove 221. The nozzle structure 2 can be separated from the gun body structure 1, and the sliding sleeve 23 can be released and reset by the tension spring 24. Conversely, the installation is also very convenient. , the atomizing nozzle 21 is inserted into the water outlet 13 of the gun body structure 1 through the positioning rod 22 on the outer wall. The positioning rod 22 first contacts the clamping block 16. Similarly, through its inclined surface, the clamping block 16 slides outward along the clamping groove 14. At the same time, the extrusion spring 17 is compressed and stored. When the clamping block 16 slides to the same position as the positioning groove 221, the extrusion spring 17 releases the elastic force, and the clamping block 16 slides along the inner wall of the positioning groove 221 to be fixedly connected to the nozzle structure 2 and the gun body structure 1. Then the threaded sleeve 18 is threadedly connected to the outer wall of the water outlet 13 and to the outer wall of the atomizing nozzle 21 to further enhance the stability of the connection. Then the rubber soft cover 19 is reset. Figure 1 As shown, the connection portion is protected, and at the same time, the outer wall of the water outlet 13 contacts the sealing ring 25 on the positioning rod 22 to ensure the sealing of the connection.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without making any creative efforts should fall within the scope of protection of the present invention.
