Detailed Implementation

[0027] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0028] Please refer to Figure 1-4 In one embodiment, this utility model provides an airbrush, comprising:

[0029] The gun body 200 is provided with an air outlet 210 and a material spraying hole 220. The material spraying hole 220 is located at the front end of the gun body 200, and the gun body 200 sprays material to the outside through the material spraying hole 220.

[0030] The spray cap 100 is detachably connected to the front end of the gun body 200. The spray cap 100 has a through hole 110, and the spray hole 220 passes through the through hole 110 in front of the through hole 110. The gas sprayed out of the gun body 200 through the air outlet 210 passes through and is sprayed to the outside.

[0031] In this embodiment, the spray cap is detachably installed at the front of the gun body. The spray nozzle passes through the through hole on the spray cap and is positioned in front of the through hole to spray out the material. Gas is sprayed out through the gap between the spray nozzle and the through hole and envelops the material flow sprayed out of the spray nozzle, so that the material can be uniformly atomized and stably sprayed in the designated direction after being sprayed out.

[0032] The spray gun features a modular design, making it easy for users to disassemble, clean, and replace parts, which helps extend the service life of the spray gun.

[0033] In a further embodiment of the present invention, both the spray hole 220 and the through hole 110 are round holes, the diameter of the through hole 110 is larger than the diameter of the spray hole 220, and the center of the spray hole 220 coincides with the center of the through hole 110.

[0034] There are gaps around the spray nozzle 220 and between it and the through hole 110.

[0035] In this embodiment, the spray nozzle 220 and the through hole 110 are coaxial. The through hole 110 has a larger diameter and completely surrounds the spray nozzle 220, allowing the airflow to evenly envelop the material flow from all sides, resulting in a stable material spray direction. The large-diameter through hole 110 improves the stability of the airflow from the gun body 200, preventing airflow turbulence. At the same time, by using the through hole 110 as a gas diffusion hole, the spray nozzle 220 is centered to achieve material focusing, enabling the spray gun to spray out fine, thread-like materials.

[0036] In a further embodiment of this utility model, a control component 300 is also provided. One end of the control component 300 is provided with a ejector pin 310. The control component 300 can move back and forth between a first open position and a first closed position. When the control component 300 is in the first closed position, one end of the ejector pin 310 abuts against the spray hole 220, and the gun body 200 cannot spray material outward through the spray hole 220.

[0037] In this embodiment, the control component 300 changes the position of the ejector pin 310 through mechanical displacement, acting as a material spray switch. When closed, the ejector pin 310 directly blocks the spray nozzle 220 to prevent material leakage. When the control component 300 moves backward, the ejector pin 310 opens and retracts from the spray nozzle 220, allowing the material to be sprayed out under the action of airflow. This achieves precise control over the spraying timing and amount, meeting different operational needs. It provides precise mechanical control for spraying start and stop, improving operational efficiency and reliability.

[0038] In a further embodiment of the present invention, the gun body 200 is also provided with a first air inlet 230 and a movable air chamber. The other end of the control component 300 is provided with an air plug 320, which is disposed in the movable air chamber. The first air inlet 230 is connected to the movable air chamber. The gun body 200 takes in air through the first air inlet 230 to push the air plug 320 and thus push the control component 300 to move from the first closed position to the first open position.

[0039] In this embodiment, the positive pressure generated by the external air intake drives the internal air plug 320 of the spray gun to move backward, enabling the control component to automatically switch states without manual operation, thereby starting or stopping material spraying. Utilizing air intake for automatic control reduces the burden of manual operation and overcomes the inconvenience and delays that may exist with manual control. Simultaneously, the air intake pushes the piston, allowing for rapid switching of spray states to adapt to fast-paced work scenarios. Automatic displacement ensures that spraying can be quickly started when needed, improving work efficiency.

[0040] In a further embodiment of the present invention, a reset component is also provided, which together with the switch component to maintain the switch in the first closed position.

[0041] In this embodiment, a spring or other mechanical reset mechanism automatically returns the control component 300 to the closed state after the external force disappears, ensuring the equipment is in a safe state. This effectively prevents accidental spraying caused by prolonged open operation and avoids material waste due to operational negligence. It also reduces the user's additional burden of monitoring the equipment status.

[0042] In a further embodiment of the present invention, a second air inlet 240 and an air inlet channel 241 are also provided. One end of the air inlet channel 241 is connected to the second air inlet 240, and the other end of the air inlet channel 241 is connected to the air outlet 210. The gun body 200 takes in air through the second air inlet 240 and sends the gas to the air outlet 210 through the air inlet channel 241.

[0043] In this embodiment, by adding a second air inlet and a dedicated gas channel, additional air guidance and mixing can be achieved on the basis of the original air output, which helps to improve the atomization effect during injection.

[0044] In a further embodiment of the present invention, an adjustment component 242 is also provided. The adjustment component 242 is movable between a second closed position and a second open position. When the adjustment component 242 is in the second closed position, one end of the air intake channel 241 and the other end of the air intake channel 241 are not connected to each other.

[0045] The adjustment component 242 is rotatably installed at the intake channel 241, with one end of the adjustment component 242 located outside the intake channel 241 and the other end located inside the intake channel 241. The user can rotate the adjustment component 242 to change the depth of the other end of the adjustment component 242 inside the intake channel 241, thereby controlling the free area of ​​the cross section of the intake channel 241 at the location of the adjustment component 242, and thus changing the airflow size inside the intake channel 241.

[0046] In this embodiment, the on / off state of the air intake channel is changed by adjusting component 242, thereby regulating the amount of gas passing through the air intake channel 241, which in turn affects the airflow and material mixing state during spraying. Users can adjust the spraying intensity and atomization effect according to actual needs, which can meet the spraying requirements of different scenarios.

[0047] In a further embodiment of the present invention, the gun body 200 is also provided with a feed hole 250 and a feed channel 251. One end of the feed channel 251 is connected to the feed hole 250, and the other end of the feed channel 251 is connected to the spray hole 220.

[0048] In this embodiment, a built-in material supply channel is constructed, which allows the material in the external storage device to be stably transported from inside the gun body to the spray end, and achieves the effect of atomized spraying by combining with airflow.

[0049] In a further embodiment of the present invention, the gun body 200 further includes a feed connector 252, which is rotatably connected to the feed hole 250.

[0050] In this embodiment, the rotating structure allows the feed connector 252 to adjust its angle in the connected state, adapting to different installation and connection methods and different working environments. This helps to ensure a tight fit at the connection point, prevent material leakage, and ensure the flexibility and sealing of the feed pipeline.

[0051] In a further embodiment of this utility model, the feed connector 252 is right-angled.

[0052] In a further embodiment of this utility model, a control component 400 is also provided at the rear end of the gun body 200. One end of the control component is located behind the air plug 320, and the control component 400 can be displaced between the third open position and the third closed position. When the control component 400 is in the third closed position, one end of the control component 400 abuts against the rear of the air plug 320, preventing the air plug 320 from moving towards the first open position. At this time, the ejector pin 310 abuts against the spray hole 220. That is, when the control component 400 is in the third closed position, the spray gun cannot spray material. When the control component 400 moves away from the third closed position towards the third open position, a gap is left between one end of the control component 400 and the air plug 320. The air plug 320 can move towards the first open position under the action of external force. That is, the ejector pin 310 can be withdrawn from the spray hole 220, and the spray gun can normally spray material through the spray hole 220.

[0053] Please refer to Figure 5 In a further embodiment of this utility model, the spray cap 100 is also provided with air holes on both sides of the through hole 110. The gas sprayed from the gun body 200 passes through the spray cap 100 through the through hole 110 and also through the air holes. It can be understood that different spray caps 100 can make the material sprayed out have different atomization effects, so that the spray gun can be used for different application scenarios.
