[0012] Compared with the prior art, the present invention provides an intelligent rotary atomizing spray gun, which has the following beneficial effects: The intelligent rotary atomizing spray gun moves the moving tube forward. When the moving tube is separated from the short tube, each hemispherical block b in the short tube will lose support. At this time, the user can move the short tube backward. When the hemispherical block a moves backward and contacts the edge of the annular wall groove, it will be squeezed and move into each circular groove respectively. At this time, the short tube can be smoothly removed, thereby removing the spray head. After the short tube is moved forward to be sleeved on the fixed tube, the moving tube is released. The moving tube is driven to move backward due to the rebound of the pressure spring a, thereby squeezing each hemispherical block b into each circular groove respectively through the moving tube, thereby driving each hemispherical block a to enter the annular wall groove, and fixing the short tube. At the same time, the connecting tube will be connected to the guide tube, and the spray head is installed. Therefore, the spray head can be quickly disassembled and installed by only moving the moving tube back and forth, which is convenient for users to quickly replace different spray heads when performing spraying operations.

[0013] The intelligent rotary atomizing spray gun can support and stabilize the moving tube through the outer tube and the supporting tube, thereby preventing the moving tube from shaking when moving without support. At the same time, the outer tube can shield the pressure spring a, thereby preventing the pressure spring a from being damaged and preventing the pressure spring a from pinching the user.

[0014] The intelligent rotary atomizing spray gun moves the short tube forward to squeeze the pressure ring forward when installing the nozzle, so that the pressure spring b contracts and accumulates force. When the nozzle needs to be removed, the moving tube is moved backward to make the hemispherical block b lose its support. The rebound of the pressure spring b drives the short tube backward through the pressure ring to make it fall off, so that the nozzle can be quickly removed.

[0015] The intelligent rotary atomizing spray gun performs a sealing process after the connecting pipe is connected to the conduit through the sealing ring a. Meanwhile, after the connecting pipe is connected to the conduit, the sealing pipe will be sleeved on the conduit, so that the sealing ring b will perform a sealing process to prevent paint leakage.

[0016] The intelligent rotary atomizing spray gun has a guide ring a, a guide ring b and a guide ring c whose cross sections are all semicircular, and they can guide each other when connecting the nozzles, so that users can quickly connect the nozzles.

[0017] The intelligent rotary atomizing spray gun can limit the small column by cooperating with each limiting ring through the annular limiting groove in each circular groove, thereby preventing the small column from falling off and preventing the small column from moving too much in the circular groove, causing the hemispherical block a and the hemispherical block b to be exposed too much and unable to drive the small column to move when squeezed.

[0018] 7. The intelligent rotary atomizing spray gun can be convenient for users to install and disassemble fixed pipes and other mechanisms through threaded pipes and connecting rings, so that users can easily perform maintenance. It can be connected to most existing nozzles through adapters, so that different nozzles can be quickly replaced when in use after connecting the nozzle to the adapter without using a designated nozzle.

Without using a specific nozzle 6, the nozzle 6 can be connected to the adapter tube 7 first to realize the rapid replacement of different nozzles 6 during use.

[0024] When in use, the first step is to move the moving tube 10 forward. When the moving tube 10 is separated from the short tube 5, each hemispherical block b32 in the short tube 5 will lose its support, and the user can move the short tube 5 backward. When the hemispherical block a18 moves backward and contacts the edge of the annular wall groove 15, it will be squeezed and move into each circular groove 19 respectively, so that the short tube 5 can be removed smoothly, and the nozzle 6 can be removed.

At the same time, the outer tube 4 can shield the pressure spring a16, thereby preventing the pressure spring a16 from being damaged and pinching the user.

[0026] Step 3: When installing the nozzle 6, the short tube 5 moves forward to squeeze the pressure ring 21 forward, so that the pressure spring b22 contracts and accumulates force. When the nozzle 6 needs to be removed, the moving tube 10 is moved backward to make the hemispherical block b32 lose its support. The rebound of the pressure spring b22 will drive the short tube 5 to move backward through the pressure ring 21 to make it fall off, so that the nozzle 6 can be quickly removed.

[0027] Step 4: After the connecting tube 24 is connected to the conduit 13, a sealing process is performed through the sealing ring a29. At the same time, after the connecting tube 24 is connected to the conduit 13, the sealing tube 20 will be sleeved on the conduit 13, so that the sealing ring b30 will perform a sealing process to prevent paint leakage.
