Description

Technical Field

[0001] This utility model belongs to the technical field of dust generating devices, and in particular relates to a dust cloud generator. Background Technology

[0002] Dust cloud generators are devices used to generate dust aerosols with specific concentrations and particle size distributions. They play an important role in scientific research, industrial testing, and environmental monitoring. Their basic working principle usually involves dispersing powdered samples into an airflow to form a uniformly suspended aerosol (dust cloud).

[0003] A dust cloud generator disclosed in the prior art, such as Chinese Patent (CN118533590A), includes: a sample chamber, an air inlet pipe, and a dust chamber; a dust sample is placed in the inner cavity of the sample chamber; the air inlet pipe is connected to the sample chamber; an air compressor pump is connected to the air inlet end of the air inlet pipe; a dust outlet is provided at the top of the sample chamber, and the dust chamber is connected to the dust outlet of the sample chamber.

[0004] This method has the following drawbacks: First, the device requires an ultrasonic oscillator to disperse the dust particles inside. However, when connecting to the ultrasonic oscillator, the device is placed directly on it, lacking a fixed connection structure. This can cause the device to shift and tip over during oscillation. Second, while the dust particles are dispersed through vibration, the vibration transmitted to the topmost particles is attenuated due to the buffering effect of the dust below. The attenuation is more pronounced as the dust thickness increases, resulting in poor dust dispersion by the oscillator. Third, after dust concentration detection experiments, the container and detector components need to be cleaned, requiring additional cleaning space and making subsequent cleaning work cumbersome.

[0005] Therefore, this utility model provides a dust cloud generator. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model discloses a dust cloud generator, which ensures that the sample bottle is stably placed above the ultrasonic cleaner, and at the same time, the vibration and breaking effect of the particles above the dust is better during the ultrasonic cleaner's vibration cleaning; it also improves the efficiency of the device in producing dust clouds, making the dust dispersion effect better; no additional cleaning space is required, and the cleaning work is simple and convenient.

[0007] To achieve the above-mentioned technical effects, this utility model provides a dust cloud generator, including an ultrasonic cleaner, a sample bottle, a dust detection bottle, and a dust detector. The sample bottle is positioned above the ultrasonic cleaner, the dust detection bottle is positioned above the sample bottle, and the dust detectors are positioned above the dust detection bottles. The support legs of the ultrasonic cleaner and the sample bottle are inserted into a fixed base on the vibrating plate of the ultrasonic cleaner. A rinsing mechanism is provided at the rear of the ultrasonic cleaner. A dispensing compartment is also provided at the bottom of the sample bottle.

[0008] Preferably, the ultrasonic cleaner has holes in its mesh plate, and the holes are positioned above the fixed base.

[0009] Preferably, a buffer pad is provided between the sample bottle and the dust detection bottle.

[0010] Preferably, the rinsing mechanism further includes a miniature water pump, a mounting base, a hose, a nozzle, and a coil. The miniature water pump is mounted on the mounting base at the rear of the ultrasonic cleaner. The inlet of the miniature water pump is connected to the inside of the ultrasonic cleaner through a pipe. The outlet of the miniature water pump is connected to the bottom end of the hose. The nozzle is located at the end of the hose. The coil is located on the left side of the miniature water pump. The miniature water pump is electrically connected to the control panel of the ultrasonic cleaner.

[0011] Preferably, the surface of the tube coil is also provided with a tube groove.

[0012] Preferably, the groove is configured as a vortex-shaped circular groove.

[0013] Preferably, a clamp is also provided at the inner end of the tube groove.

[0014] Preferably, the dispensing compartment is composed of a partition disposed at the bottom of the sample bottle, with the partition surrounding the center to form a circular area.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: The device features a fixed base and a distribution grid, ensuring the sample vials are stably positioned above the ultrasonic cleaner. During ultrasonic cleaning, vibrations transmitted from the vibrating plate are relayed through the sample vials' supports to the ends of the separators. These separators, inserted into the dust particles, transmit vibrations more effectively and efficiently, resulting in better particle breakage. Furthermore, during dust cloud formation, airflow from the sample vials is more evenly distributed into the dust particles through the separators, improving dust cloud production efficiency and enhancing dust dispersion. A rinsing mechanism is also included, allowing the entire experimental and cleaning process to be completed above the ultrasonic cleaner. Cleaning can be accomplished simply by adding water to a beaker, and wastewater can be discharged uniformly, eliminating the need for additional cleaning space and simplifying the cleaning process.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0018] The prior art in this embodiment has the following problems: The inventors have found the following defects in the prior art: First, the device needs to be used with an ultrasonic oscillator to disperse the dust particles inside the device. However, when the device is connected to the ultrasonic oscillator, it is placed directly on the ultrasonic oscillator. This lack of a fixed connection structure between the devices leads to the risk of the device shifting and tipping over during oscillation. Second, the dust in the device is dispersed by vibration. However, during the oscillation process, the vibration transmitted to the topmost particles of the dust is attenuated due to the buffering effect of the dust below. The more thick the dust used in the experiment, the more obvious the attenuation effect will be, which will result in poor dust-shattering effect of the oscillator. Third, after the dust concentration detection experiment, the container and detector in the device need to be cleaned. The cleaning process requires an additional cleaning area, making the subsequent cleaning work in the experiment cumbersome.

[0019] Therefore, as Figures 1 to 8 As shown, the inventor provides a dust cloud generator, including an ultrasonic cleaner 1, a sample bottle 2, a dust detection bottle 3, and a dust detector 4. The sample bottle 2 is positioned above the ultrasonic cleaner 1, the dust detection bottle 3 is positioned above the sample bottle 2, and the dust detector 4 is positioned above the dust detection bottle 3. The support legs 6 of the ultrasonic cleaner 1 and the sample bottle 2 are inserted into a fixed base 7 mounted on the vibrating plate 5 of the ultrasonic cleaner 1. A rinsing mechanism is provided on the rear side of the ultrasonic cleaner 1. A dispensing compartment 8 is also provided at the bottom of the sample bottle 2.

[0020] Using the above scheme, when starting the dust cloud experiment, add cleaning water to the ultrasonic cleaner 1. After connecting the air tube on the side of the sample bottle 2, place the dust sample into the bottom of the sample bottle 2 and place it on the dispensing grid 8. Then, insert the support leg 6 of the sample bottle 2 into the fixed base 7 on the vibration plate 5 of the ultrasonic cleaner 1. After filling the ultrasonic cleaner 1 with cleaning water, start the ultrasonic cleaner 1. The vibration transmitted on the vibration plate 5 will break up the powder particles inside the sample bottle 2. The vibration on the vibration plate 5 will be transmitted to the body of the sample bottle 2 through the support leg 6 of the sample bottle 2, and then to the powder particles inside the sample bottle 2 through the dispensing grid 8. After breaking up the powder particles, turn off the ultrasonic cleaner 1. The experimenter will install the dust detector 4 and the dust detection bottle 3 on top of the sample bottle 2 respectively, and then introduce gas into the sample bottle 2 to start the experiment. After the test is completed, the experimenter first removes the air tube from the side of sample bottle 2, then removes the dust detector 4 and places it into the ultrasonic cleaner 1 for cleaning. During the cleaning process, the rinsing mechanism is used to guide the water in the ultrasonic cleaner 1 into the dust detector bottle 3 for rinsing. Finally, clean water is introduced for a final rinse, and the rinsing water is discharged downwards into sample bottle 2. During the vibration cleaning process of the ultrasonic cleaner 1, the vibration is transmitted to the inside of sample bottle 2 for vibration cleaning. After the dust detector bottle 3 is cleaned, the cleaned dust detector 4 is removed from the ultrasonic cleaner 1. Then, the wastewater in sample bottle 2 is poured into the ultrasonic cleaner 1, and clean water is poured into sample bottle 2 using a beaker for a final rinse, completing the cleaning of the device. Finally, the wastewater in the ultrasonic cleaner 1 is discharged through the drain pipe to complete the experiment.

[0021] Furthermore, the mesh plate 9 of the ultrasonic cleaner 1 is provided with holes 10, and the holes 10 are positioned above the fixed base 7. Among them, the support 6 of the sample bottle 2 can directly pass through the hole 10 on the mesh plate 9 to contact the vibration plate 5 below the mesh plate 9, ensuring that the transducer below the vibration plate 5 can better transmit the vibration to the sample bottle 2, while not affecting the normal cleaning of the cleaning water on the mesh plate 9.

[0022] Furthermore, a buffer pad 11 is provided between sample bottle 2 and dust detection bottle 3; The dust detection bottle 3 is inserted into the sample bottle 2 through the lower inlet. A ring is provided between the two bottles. The buffer pad 11 made of flexible material can provide elastic support and reduce the vibration transmitted between the sample bottle 2 and the dust detection bottle 3 when the sample bottle 2 receives vibration from the ultrasonic cleaner 1.

[0023] Furthermore, the rinsing mechanism also includes a miniature water pump 12, a mounting base 13, a hose 14, a nozzle 15, and a coil 16. The miniature water pump 12 is mounted on the mounting base 13 on the rear side of the ultrasonic cleaner 1. The inlet of the miniature water pump 12 is connected to the inside of the ultrasonic cleaner 1 through a pipe. The outlet of the miniature water pump 12 is connected to the bottom end of the hose 14. The nozzle 15 is located at the end of the hose 14. The coil 16 is located on the left side of the miniature water pump 12. The miniature water pump 12 is electrically connected to the control panel 20 of the ultrasonic cleaner 1. In this process, when the technician completes the testing and begins the cleaning operation, the hose 14 and nozzle 15 are removed from the tube tray 16 and aligned with the inside and outside of the dust detection bottle 3. The micro water pump 12 can be started via the control panel 20. The micro water pump 12 pumps water from the ultrasonic cleaner 1 into the nozzle 15 for rinsing. The wastewater after rinsing can be stored in the sample bottle 2. During the cleaning process, the sample bottle 2 receives the wastewater poured in from above and simultaneously receives vibrations from the ultrasonic cleaner 1. The wastewater cleans the inner wall of the sample bottle 2 under the action of vibration. At the same time, the nozzle 15 can be used to clean the outside of the sample bottle 2. The wastewater after cleaning is poured directly into the inside of the ultrasonic cleaner 1 and discharged uniformly. In this way, the entire experiment and cleaning process is completed above the ultrasonic cleaner 1. Only some cleaning water needs to be poured into a beaker to complete the cleaning. The wastewater generated during cleaning can also be discharged uniformly. This eliminates the need for an additional cleaning area, making the cleaning work simple and convenient.

[0024] Furthermore, the surface of the tube coil 16 is also provided with a tube groove 17; After use, the flushing mechanism can insert the hose 14 into the pipe groove 17 for storage, reducing the space occupied by the hose 14.

[0025] Furthermore, the groove 17 is configured as a vortex-shaped circular groove; The vortex-shaped groove allows the end of the hose 14 to be inserted into the groove 17 from the outermost side of the groove for secure storage.

[0026] Furthermore, a clamp 18 is also provided at the inner end of the tube groove 17; After the hose 14 is inserted into the groove 17, the nozzle 15 at the end of the groove 17 can be inserted into the clamp 18 for fixed placement.

[0027] Furthermore, the material distribution compartment 8 is composed of a partition 19 disposed at the bottom of the sample bottle 2, and the partition 19 forms a circular area around the center. The separator 19 is arranged around the bottom of the sample bottle. When the dust is placed above the dispensing grid 8, the separator 19 separates the dust sample. At the same time, the separator 19 is inserted into the dust. In this way, when the ultrasonic cleaner 1 vibrates and cleans, the vibration transmitted from the vibrating plate 5 is transmitted to the end of the separator 19 through the support leg 6 of the sample bottle 2. The separator 19 inserted into the dust can transmit the vibration to the dust more effectively and at a lower level, resulting in a better vibration and crushing effect on the particles above the dust. Furthermore, during the dust cloud production process, the airflow blown in from the air tube of sample bottle 2 can be more evenly dispersed into the dust through the partition 19, improving the efficiency of the device in producing dust clouds and making the dust distribution effect better.

[0028] In summary, the device is equipped with a fixed base 7 and a distribution grid 8, which ensures that the sample bottle 2 is stably positioned above the ultrasonic cleaner 1. During the ultrasonic cleaner 1's vibration cleaning, the vibration transmitted from the vibrating plate 5 is transmitted through the support legs 6 of the sample bottle 2 to the end of the partition 19. The partition 19, inserted into the dust, can better transmit the vibration to the dust, resulting in better vibration and crushing effect on the particles above the dust. Furthermore, during the dust cloud production process, the airflow blown in from the air tube of the sample bottle 2 can be more evenly dispersed into the dust through the partition 19, improving the efficiency of the device in producing dust clouds and making the dust dispersion effect better. A rinsing mechanism is also provided, and the entire experiment and cleaning process is completed above the ultrasonic cleaner 1. Only some cleaning water needs to be poured into a beaker to complete the cleaning, and the wastewater generated during cleaning can also be discharged uniformly. This eliminates the need for an additional cleaning area, making the cleaning work simple and convenient.

[0029] The working principle of this utility model: When starting the dust cloud experiment, add cleaning water to the ultrasonic cleaner 1. After connecting the air tube on the side of the sample bottle 2, put the dust sample into the bottom of the sample bottle 2 and place it on the dispensing grid 8. The partition 19 is arranged around the bottom of the sample bottle. When the dust is placed above the dispensing grid 8, the partition 19 separates the dust sample. At the same time, the partition 19 is inserted into the dust. In this way, when the ultrasonic cleaner 1 vibrates and cleans, the vibration transmitted from the vibrating plate 5 is transmitted to the end of the partition 19 through the support leg 6 of the sample bottle 2. The partition 19 inserted into the dust can better transmit the vibration to the dust, and the vibration and breaking effect on the particles above the dust is better. Then insert the support 6 of sample bottle 2 into the fixed base 7 on the vibrating plate 5 of ultrasonic cleaner 1. The support 6 of sample bottle 2 can directly pass through the hole 10 on the mesh plate 9 and contact the vibrating plate 5 below the mesh plate 9. After filling the ultrasonic cleaner 1 with cleaning water, start the ultrasonic cleaner 1 and use the vibration transmitted on the vibrating plate 5 to break up the powder particles inside sample bottle 2. After crushing the powder particles, turn off the ultrasonic cleaner 1. The experimenter installs the dust detector 4 and the dust detection bottle 3 on top of the sample bottle 2 respectively, and then introduces gas into the sample bottle 2 to start the experimental detection. After the test is completed, the technician first removes the air tube from the side of sample bottle 2, then removes the dust detector 4 and places it in the ultrasonic cleaner 1 for cleaning. While the technician is cleaning after the test, the hose 14 and nozzle 15 are removed from the tube tray 16 and aligned with the inside and outside of the dust detection bottle 3. The micro water pump 12 can be started through the control panel 20. The micro water pump 12 pumps water from the ultrasonic cleaner 1 into the nozzle 15 for rinsing. The wastewater after rinsing can be stored in sample bottle 2. Sample bottle 2 receives the water poured in from above during the cleaning process. Wastewater simultaneously receives vibrations from the ultrasonic cleaner 1, causing the wastewater to clean the inner wall of the sample bottle 2 under the action of vibration. At the same time, the nozzle 15 can be used to clean the outside of the sample bottle 2. After the dust detection bottle 3 is cleaned, the dust detector 4 that has been cleaned in the ultrasonic cleaner 1 is taken out first. Then, the wastewater in the sample bottle 2 is poured into the ultrasonic cleaner 1. Clean water is poured into the sample bottle 2 with a beaker for a final rinse to complete the cleaning of the device. After that, the wastewater in the ultrasonic cleaner 1 is discharged through the drain pipe to complete the experiment. The entire experiment and cleaning process is completed above the ultrasonic cleaner 1. You only need to pour some cleaning water into a beaker to complete the cleaning. The wastewater generated during cleaning can also be discharged in a unified manner. This eliminates the need for an additional cleaning site, making the cleaning work simple and convenient. This concludes the description of the working principle of the device.
