[0002] With the continuous progress in environmental science, materials research, and air quality testing, aerosol generators, as a device that can simulate particulate matter in the atmosphere, are used to study the complex impact of tiny particles on human health and the natural environment. In the context of air quality becoming an issue of great concern to the whole society, the effective collection and in-depth analysis of atmospheric particulate matter are particularly important. Aerosol generators are a device that converts liquid or solid substances into gaseous particles. They play an irreplaceable role in promoting environmental science research, promoting material technology innovation, and improving air quality testing capabilities.

[0003] Currently, the operating pressure range of most aerosol generators is relatively low and cannot be used in application scenarios with higher pressures. At the same time, most nozzles are of fixed size and the air intake volume cannot be adjusted, resulting in the generated aerosol particle size distribution and quality not fully meeting specific needs, affecting the flexibility of the experiment.

[0004] Therefore, those skilled in the art provide a high-pressure aerosol generator device to solve the problems raised in the above background technology. Utility Model Content

[0005] The purpose of the utility model is to address the shortcomings of the prior art and to propose a high-pressure aerosol generator device, which uses a pressure regulating valve to adjust the compressed air to an appropriate pressure and generates a high-speed airflow through a nozzle, thereby being able to generate an aerosol with a specific particle size distribution under high-pressure conditions to meet the needs of high-pressure testing.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] A high-pressure aerosol generator device includes a fixed cover, a regulating mechanism is provided on the upper end of the fixed cover, the regulating mechanism includes an air distributor, multiple pressure regulating valves, multiple first ferrule joints, multiple air pipes, a second ferrule joint, multiple nozzle bodies, multiple nozzle collars and multiple connection ports, and an air inlet nozzle is fixedly provided on the upper end of the air distributor;

[0008] A blocking piece is fixedly provided on the inner side of the lower end of the fixed cover, and a sealing ring is fixedly provided on the outer side of the lower end of the fixed cover.

[0009] Furthermore, the exterior of the plurality of connection ports is opened on the exterior of the air distributor near the upper end, and the plurality of pressure regulating valves are fixedly arranged on opposite sides of each other inside the plurality of connection ports.

[0012] Furthermore, the inner parts of the plurality of nozzle collars are fixedly arranged on the outer parts of the plurality of nozzle bodies near the lower ends, and the lower end of the second ferrule joint is fixedly arranged on the upper end of the fixed cover.

[0013] Furthermore, the plurality of nozzle bodies are all made of stainless steel, and the air distributor is also made of stainless steel.

[0014] Furthermore, a chuck is fixedly provided at the lower end of the sealing ring, and a shell is fixedly provided at the lower end of the chuck.

[0015] The utility model has the following beneficial effects:

[0016] 1. The utility model proposes a high-pressure aerosol generator device, which injects compressed air into the interior of an air distributor through an air inlet nozzle and then adjusts the pressure to different levels through a pressure regulating valve. The resulting airflow forms a negative pressure area when entering the liquid, attracting and carrying tiny droplets. When this high-speed airflow carrying droplets passes through the aerosol stock solution, larger particles cannot move with the airflow and remain in the stock solution. At the same time, the tiny particles are gradually dispersed and diffused in the air with the help of the force of the high-speed airflow. The final aerosol not only ensures the concentration and uniformity of the aerosol, but also realizes the fine control of the aerosol particle size.

[0017] 2. The utility model proposes a high-pressure aerosol generator device with a higher working pressure range of up to 12 bar, which can meet the application requirements in high-pressure environments. By adjusting the number of openings of multiple pressure-regulating valves, the device can flexibly adjust the concentration of the aerosol to meet the experimental requirements of different concentrations from low to high, thereby improving the flexibility and accuracy of the experiment.

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Reference Figure 1 、 Figure 2 、 Figure 3 and Figure 4 , an embodiment provided by the utility model:

[0026] A high-pressure aerosol generator device includes a fixed cover 2, a regulating mechanism 5 is provided on the upper end of the fixed cover 2, the regulating mechanism 5 includes an air distributor 501, multiple pressure regulating valves 502, multiple first ferrule joints 503, multiple air pipes 504, a second ferrule joint 505, multiple nozzle bodies 506, multiple nozzle collars 507 and multiple connecting ports 508, an air inlet nozzle 1 is fixedly provided on the upper end of the air distributor 501, multiple connecting ports 508 are externally opened on the upper end of the air distributor 501, multiple pressure regulating valves 502 are fixedly provided on opposite sides of each other in the multiple connecting ports 508, and multiple air pipes 504 input ends are fixedly provided The plurality of pressure regulating valves 502 are disposed at the output ends, the plurality of air pipes 504 output ends are respectively fixedly disposed at the input ends of the plurality of first ferrule joints 503, the exteriors of the plurality of first ferrule joints 503 are all fixedly disposed inside the fixed cover 2, the plurality of nozzle bodies 506 input ends are respectively fixedly disposed at the output ends of the plurality of first ferrule joints 503, the interiors of the plurality of nozzle collars 507 are respectively fixedly disposed at the exteriors of the plurality of nozzle bodies 506 near the lower ends, the lower end of the second ferrule joint 505 is fixedly disposed at the upper end of the fixed cover 2, the plurality of nozzle bodies 506 are all made of stainless steel, the air distributor 501 is made of stainless steel, and a baffle 7 is fixedly disposed on the interior of the lower end of the fixed cover 2;

[0027] Specifically, during the test, compressed air is passed from the air inlet nozzle 1 into the air distributor 501, and the air distributor 501 distributes the air to each pressure regulating valve 502. Then, the air pressure in front of each nozzle can be adjusted through the pressure regulating valve 502, thereby controlling the concentration and particle size of the aerosol. During the operation of the aerosol generator, the opening state of the pressure regulating valve 502 is not fixed, but is flexibly adjusted according to the required aerosol concentration. When a higher concentration of aerosol is required, the number of opened pressure regulating valves 502 is increased accordingly to ensure that more compressed air can pass through the nozzle body 506, thereby enhancing the carrying capacity of the airflow and the dispersion effect of the droplets. Conversely, when a lower concentration of aerosol is required, the number of opened pressure regulating valves 502 is reduced to achieve the expected concentration requirement, which not only achieves precise control of the aerosol concentration, but also improves the flexibility and energy efficiency of the device. The regulated air flows through the air pipe 504 to the first ferrule joint 503, and is then transmitted to the nozzle body 506. At the moment the airflow enters the liquid, a temperature drop occurs. The Churri effect creates a negative pressure area at the liquid interface. This negative pressure effect acts like a natural attraction, effectively carrying and rolling up tiny droplets. Subsequently, when this airflow carrying droplets passes through the liquid layer, the liquid itself acts like a filter baffle, effectively separating and blocking larger particles, allowing only tiny particles to continue to disperse and diffuse into the surrounding environment with the high-speed airflow. This not only improves the efficiency of aerosol generation, but also ensures the uniformity and stability of the aerosol, providing high-quality samples for subsequent particulate matter analysis. The nozzle body 506 ensures that the aerosol has a specific particle size distribution. The nozzle collar 507 helps position the nozzle body 506 and ensures a good connection between the nozzle and the fixed cover 2. The second ferrule connector 505 is the aerosol outlet. The overall structure is compact and durable. By using stainless steel, the service life and stability of the device are guaranteed. The concentration and particle size of the aerosol can be controlled by adjusting the number and pressure setting of the pressure regulating valve 502, thereby achieving efficient and stable aerosol generation and meeting the needs of high-voltage testing.

[0028] Reference Figure 1 、 Figure 2 、 Figure 3 and Figure 4 , a sealing ring 6 is fixedly provided on the outside of the lower end of the fixed cover 2, a chuck 3 is fixedly provided on the lower end of the sealing ring 6, and a housing 4 is fixedly provided on the lower end of the chuck 3;

[0029] Specifically, the sealing ring 6 improves the safety and airtightness of the device operation and prevents leakage. The coordinated use of the chuck 3 and the shell 4 facilitates the assembly and maintenance of the equipment, while also protecting the internal components from interference from external factors. The maximum working pressure of the device can reach 12 bar, which is suitable for a variety of application scenarios requiring high-pressure aerosols.

[0030] Working principle: During operation, the compressed air is first delivered to the inside of the air distributor 501 through the air inlet nozzle 1. The air distributor 501 is responsible for evenly distributing the compressed air to multiple pressure regulating valves 502. The pressure regulating valve 502 is used to adjust the pressure of the compressed air entering the nozzle body 506. The pressure of the compressed air determines the intensity of the negative pressure generated by the airflow discharged from the nozzle, thereby affecting the amount and quality of aerosol produced. The connection between the pressure regulating valve 502 and the first ferrule joint 503 is achieved through the air pipe 504. One end of the air pipe 504 is connected to the pressure regulating valve 502, and the other end is connected to the When the airflow passes through the nozzle body 506, a negative pressure area will be generated in the liquid, forming a Venturi effect, causing the liquid to be sucked in and broken into tiny droplets, so that the droplets are then carried away by the high-speed airflow and gradually dispersed in the air to form aerosols. When the compressed air passes through the area containing the liquid, larger particles will remain in the liquid due to gravity, while smaller particles will be carried away by the airflow. With the diffusion of the airflow, these tiny particles will gradually disperse to form aerosols, so that the generated aerosol concentration is high and stable, which is conducive to the accuracy and reliability of the experimental results.

[0031] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
