Description

Technical Field

[0001] This utility model relates to the field of fogging technology, and in particular to a high-pressure gas atomization device. Background Technology

[0002] A stage is the space provided in a theater for actors to perform, allowing the audience to focus their attention on the actors and achieve an ideal viewing experience. A stage typically consists of one or more platforms, some of which can be raised and lowered. Types of stages include proscenium stages, extended stages, circular stages, and rotating stages. With technological advancements, the viewing experience can be greatly enhanced through atmospheric effects such as lighting, pyrotechnics, and smoke.

[0003] There are two main methods for generating water mist: one involves condensing water vapor in the air into mist, and the other involves directly atomizing water using mechanical energy. Directly atomizing water requires high pressure and specialized nozzles to achieve large-scale atomization. Furthermore, ultrasonic atomization methods produce insufficient mist and are unsuitable for stage applications. Directly pressurizing water through specialized nozzles places high demands on the entire piping system. Similarly, using dry ice for mist generation increases the carbon dioxide concentration in the stage area, posing a potential risk. Utility Model Content

[0004] To address the aforementioned problems, this utility model discloses a high-pressure gas atomizing device, comprising a base, an air compressor housed inside the base, a gas tank fixedly connected to the upper end of the base, and the lower end of the gas tank fixedly connected to the output end of the air compressor. A vertically arranged venturi tube is fixedly connected to the upper end of the gas tank, the venturi tube including a throat located in the middle. That is, the air compressor pumps gas into the gas tank to create a high-pressure state, and the high-pressure gas is delivered out from the venturi tube.

[0005] The throat includes an annular body with a narrowed channel in its center and a protrusion on the middle sidewall of the channel. An annular chamber and a water channel are located inside the annular body, with one end connected to the annular chamber and the other end extending from the inclined surface of the protrusion. When high-pressure gas passes through the throat, it is further pressurized and impacts the water exiting the water channel, atomizing it into a mist, which is then mixed during subsequent transport. The high-pressure gas, i.e., the high-speed airflow, propels the water mist a longer distance, facilitating the creation of a larger water mist area.

[0006] Preferably, the venturi further includes an inlet section and a diffuser section, both of which are fixedly connected to the throat via flanges, and the bolts on the flanges engage with pre-drilled threaded holes on the ring body. Due to the complex structure of the throat, it is produced in sections, and the throat is obtained using 3D printing.

[0007] Preferably, a water inlet is fixedly connected to the side wall of the ring body, and the water inlet communicates with the annular chamber. One end of the water inlet is fixedly connected to a water inlet pipe. Water is supplied from the external water inlet pipe, and the water passes through the annular chamber and waterway, finally entering the narrowing channel.

[0008] Preferably, an electromagnetic valve is fixedly connected to the upper opening of the gas cylinder, and the other end of the electromagnetic valve is connected to the inlet section. When the electromagnetic valve opens, the gas cylinder enters the venturi tube.

[0009] Preferably, the side wall of the base is provided with a mesh, and several support feet are fixedly connected to the lower end of the base. The mesh facilitates the air compressor's smooth air extraction.

[0010] Preferably, a protective shell is fitted onto the upper end of the base, and a venturi tube extends from the upper end of the protective shell. The protective shell protects the gas tank and the upper structure, while also improving the aesthetics of the device.

[0011] The beneficial effects of this utility model are as follows: It is equipped with a venturi tube, and the high-pressure gas is accelerated at the throat after passing through the venturi tube. Water is injected from the throat, and water mist is formed by the impact of high-speed gas on water. This method is relatively simple and has low requirements. At the same time, the gas and water mist are fully mixed after entering the diffusion section, which has the advantage of good uniform mist formation. In addition, this utility model can be used independently without the need for external high-pressure pipelines. Attached Figure Description

The lower end of the gas tank 7 is fixedly connected to the output end of the air compressor. When the air compressor is working, it pumps air into the interior of the gas tank 7. A vertically arranged venturi tube 6 is fixedly connected to the upper end of the gas tank 7, so that the high-pressure gas in the gas tank 7 will pass through the venturi tube 6. The venturi tube 6 includes a throat 62 located in the middle. The high-pressure gas is accelerated when it passes through the throat 62.

[0022] The throat 62 includes an annular body 621, with a narrowed channel in the middle of the annular body 621 and a protrusion 625 on the middle side wall of the channel.

One end of the water channel 626 is connected to the annular chamber 624, and the other end extends from the inclined surface of the protrusion 625. During atomization, water is pumped into the annular chamber 624, and the water enters the water channel 626 and is sent out from the protrusion 625. Under the impact of the high-speed airflow, the water is impacted to form water mist. Since the structure of the throat tube 62 is relatively complex, it is not easy to obtain by conventional manufacturing methods. Here, the throat tube 62 is obtained by Xuanyuan 3D printing.

[0023] The venturi tube 6 also includes an inlet section 61 and a diffuser section 63. Both the inlet section 61 and the diffuser section 63 are fixedly connected by a flange and a throat 62. The bolts on the flange are fitted into the threaded holes 622 pre-set on the ring body 621, that is, the bolts pass through the flange and are threadedly connected to the threaded holes 622.

One end of the water inlet 623 is fixedly connected to a water inlet pipe 5, and water is pumped into the water inlet pipe 5, and the water enters the annular chamber 624.

[0025] A solenoid valve 8 is fixedly connected to the upper opening of the gas tank 7, and the other end of the solenoid valve 8 is connected to the inlet section 61. When the solenoid valve 8 is activated, the gas in the gas tank 7 passes through the solenoid valve 8 and is delivered out through the venturi tube 6.

[0026] The side wall of the base 2 is provided with mesh holes 3, which facilitates the air compressor to draw air from the outside. Several support feet 1 are fixedly connected to the lower end of the base 2, and the support feet 1 are used to set the base 2 off the ground.
