Description

Technical Field

[0001] This utility model belongs to the field of spray gun technology, and in particular relates to a dual-fluid rapid cooling spray gun. Background Technology

[0002] A spray gun is a device that uses the rapid release of liquid or compressed air as a power source. Spray guns are divided into two types: standard pressure and pressurized pressure.

[0003] Existing spray guns typically consist of multiple outer shell components, such as the gun body, gun head, and connecting seat. This necessitates sealing the mating surfaces between these components during manufacturing, which can easily increase production costs and lead to leakage during use. Therefore, we have specially designed a dual-fluid quench spray gun. Utility Model Content

[0005] In view of this, the present invention provides a dual-fluid quenching spray gun, which further includes:

[0006] The gun body has a mounting cavity inside, a spray nozzle at the front end, and an end cap connected to the rear end.

[0007] Speed-increasing component, which is set inside the mounting cavity, and an atomizing cavity is formed between the speed-increasing component and the nozzle;

[0008] The atomizing component is located inside the atomizing chamber and at the front end of the speed-increasing component. The atomizing component is connected to the speed-increasing component.

[0009] The end cap is equipped with a liquid inlet and an air inlet.

[0010] In the above technical solution, the speed-up components further include:

[0011] The main body, with flow channels inside;

[0018] A connecting rod is provided with a mating rod. The end of the connecting rod is provided with a first thread, and the end of the mating rod is provided with a second thread.

[0019] The atomizing element includes a frame and an atomizing mesh. The frame has fixing holes that connect to a mating rod, and the atomizing mesh is set on the frame.

[0020] The main body is provided with screw holes corresponding to the connecting rods, and the screw holes are connected to the connecting rods;

[0021] The end of the mating rod passes through the fixing hole and is connected to a nut.

[0022] Furthermore, in the above technical solution, multiple sets of atomizing components are provided.

[0023] Furthermore, the above technical solution also includes:

[0024] The positioning block has a connection hole with an opening. The positioning block is set on the mating rod and is located between adjacent atomizing components.

[0038] Speed-increasing component 4 is disposed in the mounting cavity 11, and an atomizing cavity 5 is formed between speed-increasing component 4 and spray hole 2.

[0039] The atomizing component is located inside the atomizing chamber 5 and at the front end of the speed-increasing component 4. The atomizing component is connected to the speed-increasing component 4.

[0040] The end cap 3 is provided with a liquid inlet end 31 and an air inlet end 32.

[0041] As can be seen from this embodiment, a dual-fluid ultra-cold spray gun includes a gun body 1, a speed-increasing component 4, and an atomizing component;

[0042] The gun body 1 has an installation cavity 11 formed inside. The front end of the gun body 1 is provided with a spray hole 2. The rear end of the gun body 1 is connected to an end cap 3. The end cap 3 has a liquid inlet end 31 and an air inlet end 32 formed on it. The liquid inlet end 31 and the air inlet end 32 are respectively connected to an external water supply pipe and an air supply pipe.

[0043] The speed-increasing component 4 is installed in the mounting cavity 11, and the speed-increasing component 4 and the nozzle 2 at the front end of the gun body 1 form an atomizing cavity 5, in which an atomizing component is installed.

[0044] The gas-liquid mixture is accelerated by the speed-increasing component 4 and then impacts the atomizing component in the atomizing chamber 5, and atomization occurs during the impact process.

[0045] The gun body 1 is a one-piece cast structure, and is only connected to the end cap 3 as an assembly to seal the mounting cavity 11 inside the gun body 1. This reduces the use of seals, lowers production costs, and facilitates the installation of the booster and atomizing components during production. Furthermore, the speed-increasing component 4 and the atomizing component are compactly structured within the mounting cavity 11, which helps to reduce the volume of the gun body 1 and facilitates subsequent use.

A flow channel 411 is formed inside the main body 41, and the flow channel 411 is funnel-shaped. The flow guide 42 is installed in the large end of the flow channel 411.

[0054] In use, the gas-liquid mixture enters through the large end of the flow channel 411 and is output through the small end of the flow channel 411. The flow rate of the gas-liquid mixture is increased through the funnel device structure of the flow channel 411. At the same time, the guide frame 42 is installed inside the large end of the flow channel 411. The guide frame 42 can guide the gas-liquid mixture to generate vortices, which helps to increase the fluid flow rate.

[0061] The flow guide 42 is funnel-shaped and fits inside the large end of the flow channel 411. The fins 422 are formed on the inner wall of the flow guide 42 and have an inclination angle.

[0062] When in use, the gas-liquid mixture enters the guide frame 42 and generates vortices through the inclination angle of the fins 422 during the contact process, which can effectively increase the fluid flow rate.
