[0002] High-pressure micro-dust generators are mainly used in basic scenarios such as air filter performance testing and dust monitoring instrument calibration. They are widely used in industries such as environmental monitoring, industrial production, and cleanroom testing. Their core function is to generate a quantitative amount of micro-dust aerosols to meet basic testing needs. Currently, high-pressure micro-dust generators on the market mainly consist of a dust storage tank, a high-pressure airflow interface, a simple discharge structure, and a manual control switch. They primarily use high-pressure airflow to uniformly release dust, thereby achieving stable dust supply and assisting in basic testing. Existing high-pressure micro-dust generators suffer from excessively long dust emission times in practical applications such as air filter testing and instrument calibration, resulting in low efficiency of basic testing processes and impacting user experience. To address this issue, a new high-pressure micro-dust generator is proposed. Utility Model Content

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Reference Figure 1 The present invention provides an embodiment of a high-pressure micro-dust generator, comprising a housing 1, a sliding groove 2 inside the housing 1, a pressurizing component 3 outside the sliding groove 2, a dust-containing component 4 on the top of the pressurizing component 3, and a dust-generating component 5 on the top of the dust-containing component 4. The outer casing 1 provides the installation support base for the entire equipment, the slide 2 provides guidance and limit for the movement of the pressurizing component 3, the pressurizing component 3 can apply pressure to the dust in the dust holding component 4, push the dust to the dust generating component 5, and finally the dust generating component 5 sprays out the dust in a small amount. All components work together to form a complete dust generating process.

[0017] Reference Figures 1-4 The slide 2 includes a base plate 6, which is fixedly connected to the inner wall of the outer shell 1. A fixing plate 8 is fixedly connected to the top of the base plate 6, and a bracket 7 is fixedly connected to the top of the base plate 6. A second threaded rod 20 is rotatably connected between the bracket 7 and the fixing plate 8. A first threaded rod 9 is rotatably connected between the bracket 7 and the fixing plate 8. Three slide rods 19 are fixedly connected between the bracket 7 and the fixing plate 8. A limit ring 22 is slidably connected to the outer wall of the first threaded rod 9. Four long rods 23 are fixedly connected to the outer wall of the limit ring 22. Among them, the long rod 23 closest to the second threaded rod 20 is threadedly connected to the outer wall of the second threaded rod 20, and the remaining long rods 23 are slidably connected to the outer wall of the slide rod 19. The base plate 6, bracket 7, and fixing plate 8 form the support frame of the slide 2, providing a stable mounting carrier for the first threaded rod 9, the second threaded rod 20, and the slide rod 19. Before use, observe the dust capacity inside the dust collection tube 14. According to the dust capacity requirements, when the second threaded rod 20 rotates, it can drive the long rod 23 connected to it to move, thereby driving the limiting ring 22 to slide along the first threaded rod 9. The remaining long rods 23 slide along the slide rod 19 to ensure the stability of the limiting ring 22 during movement. By adjusting the position of the limiting ring 22, the moving endpoint of the linkage rod 12 can be preset, so that the linkage rod 12 can quickly reach the target position when moving later, reducing waiting time.

[0018] Reference Figures 1-4 The pressurizing component 3 includes a linkage rod 12, which is threaded to the outer wall of the first threaded rod 9. A groove 2 is provided on the outer wall of the outer shell 1. The linkage rod 12 is slidably connected to the inner wall of the groove 2. A pressurizing column 13 is fixedly connected to the top of the linkage rod 12. When the first threaded rod 9 rotates, it drives the linkage rod 12 to slide along the groove 2 on the outer wall of the outer shell 1 through the threaded transmission. The groove 2 further limits the movement direction of the linkage rod 12 to prevent deviation. The linkage rod 12 synchronously drives the pressure column 13 at the top to move up and down. When the pressure column 13 moves downward, it can move away from the dust holding component 4 to facilitate the replenishment of dust. When it moves upward, it can extend into the dust holding component 4 to apply pressure to the dust, providing power for the dust to be transported to the dust generating component 5.

[0019] Reference Figure 2 The dust collection assembly 4 includes a dust collection tube 14, which is slidably connected to the outer wall of the pressurizing column 13, and a fixed bracket 15 is fixedly connected to the top of the dust collection tube 14. The dust collection tube 14 serves as a dust storage container, providing a closed storage space for the dust and preventing premature leakage. The pressure column 13 can slide along the inner wall of the dust collection tube 14, and the pressure generated during its sliding can push the dust in the dust collection tube 14 to the top. The fixed bracket 15 is used to fix and support the dust generating component 5, so that the dust generating component 5 and the dust collection tube 14 maintain a stable relative position, ensuring that the dust can be accurately delivered to the dust generating component 5.

[0020] Reference Figures 1-3 The dust generating component 5 includes a power component 16, which is fixedly connected to the top of the fixed bracket 15. A conveying pipe 17 is fixedly connected to the outside of the power component 16, and a dust generating head 18 is fixedly connected to the outside of the conveying pipe 17. The power unit 16 provides power for the final ejection of dust, which can suck in the dust pushed under pressure in the dust collection tube 14 and form a stable micro airflow through power drive; the delivery tube 17 serves as the dust delivery channel, guiding the dust processed by the power unit 16 to the dust generator head 18; the dust generator head 18 regulates the dust airflow, so that the dust is ejected in the form of uniform micro aerosol, which meets the usage requirements of scenarios such as air filter testing and instrument calibration.

[0021] Reference Figures 2-3 The bottom of the first threaded rod 9 is fixedly connected to the first gear 10, and the bottom of the base plate 6 is rotatably connected to the second gear 11. The first gear 10 is rotatably connected to the bottom of the base plate 6, and the first gear 10 and the second gear 11 mesh. The first gear 10 rotates synchronously with the first threaded rod 9. The second gear 11 transmits power through meshing with the first gear 10. When the second gear 11 rotates, it can drive the first gear 10 to rotate synchronously, thereby driving the first threaded rod 9 to rotate and converting the power into the rotational motion of the first threaded rod 9, providing driving force for the sliding of the linkage rod 12 of the pressurizing assembly 3.

[0022] Reference Figure 2 The top of the base plate 6 is fixedly connected to the second motor 24, and the output end of the second motor 24 is fixedly connected to the top of the second gear 11 through the base plate 6. The second motor 24 provides a power source for the rotation of the first threaded rod 9. After the second motor 24 is started, its output end can directly drive the second gear 11 to rotate. Through the meshing transmission between the second gear 11 and the first gear 10, the power of the motor is transmitted to the first gear 10 and the first threaded rod 9 in sequence, so as to realize the stable output and transmission of power and ensure that the pressurizing component 3 can continuously and stably complete the pressurizing action.

[0023] Reference Figure 4 The first motor 21 is fixedly connected to the top of the bracket 7, and the output end of the first motor 21 is fixedly connected to the top of the second threaded rod 20 through the bracket 7. The first motor 21 provides a power source for adjusting the position of the limiting ring 22. Based on the dust volume observed in the dust collection pipe 14, the first motor 21 is started, and its output end can directly drive the second threaded rod 20 to rotate. The second threaded rod 20 is connected to the adjacent long rod 23 by a thread, which drives the long rod 23 and the limiting ring 22 to move smoothly along the slide bar 19 until the limiting ring 22 reaches the preset position, thereby achieving precise limitation of the moving end point of the linkage rod 12, ensuring that the linkage rod 12 can quickly reach the target position and shorten the waiting time for dust discharge.

[0024] Working principle: When the high-pressure micro-dust generator is working, first observe the dust capacity inside the dust collection tube 14 in the dust collection assembly 4, and then start the first motor 21 at the top of the bracket 7. The output end of the first motor 21 drives the second threaded rod 20 to rotate. Since the long rod 23 near the second threaded rod 20 among the four long rods 23 fixed on the outer wall of the limiting ring 22 is threadedly connected to the second threaded rod 20, and the remaining long rods 23 are slidably connected to the outer wall of the three sliding rods 19 between the bracket 7 and the fixed plate 8, the rotation of the second threaded rod 20 will drive the long rods 23 and the limiting ring 22 to slide smoothly along the first threaded rod 9 until the limiting ring 22 reaches the preset position to limit the movement endpoint of the linkage rod 12, ensuring that the subsequent linkage rod 12 can quickly reach the target position; The second motor 24 at the top of the base plate 6 is activated. The output of the second motor 24 drives the second gear 11 at the bottom of the base plate 6 to rotate. The second gear 11 meshes with the first gear 10 fixed at the bottom of the first threaded rod 9, thereby driving the first threaded rod 9 to rotate. The linkage rod 12, which is threaded to the first threaded rod 9, slides along the slide groove 2 on the outer wall of the outer shell 1. The slide groove 2 guides and limits the linkage rod 12. The linkage rod 12 synchronously drives the pressure column 13 at the top to move upward and extend into the dust collection tube 14, applying pressure to the dust in the dust collection tube 14 and pushing the dust to the top. In the dust-generating assembly 5, which is fixedly supported by the fixed bracket 15, the power assembly 16 sucks in the pressurized dust, drives it to form a stable micro-airflow, and then guides it to the dust-generating head 18 through the external delivery pipe 17. After the dust-generating head 18 regulates the dust airflow, it sprays the dust out in the form of uniform micro-aerosol. Throughout the process, the outer shell 1 provides the installation support base for each component, and the base plate 6, bracket 7 and fixed plate 8 form the support frame of the slide 2 to ensure the stable operation of each component. Finally, the dust-generating operation is completed to meet the needs of scenarios such as air filter testing and instrument calibration.

[0025] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
