Abstract
Description
Technical Field
[0001] This utility model relates to the field of aerosol sampling technology, and in particular to a portable aerosol sampler. Background Technology
[0002] Aerosols are gaseous dispersion systems composed of solid or liquid particles suspended in a gaseous medium, and they play a vital role in environmental monitoring, healthcare, and industrial production. For example, in environmental monitoring, sampling and analyzing atmospheric aerosols can reveal the types, concentrations, and distribution of pollutants in the air, providing a basis for air quality assessment and pollution control. In healthcare, sampling and detecting airborne microbial aerosols helps prevent and control the spread of infectious diseases. In industrial production, monitoring aerosols ensures a safe production environment and product quality.
[0003] Portable aerosol samplers are widely used for field sampling due to their small size, light weight, and ease of operation. They can be easily carried to different locations, such as outdoor environments, indoor spaces, and workshops, to achieve real-time aerosol sampling. However, traditional portable aerosol samplers also face some problems during use.
[0004] During prolonged sampling, the sampling port and internal channels of the sampler may become clogged due to the accumulation of aerosol particles, affecting sampling efficiency and accuracy. If previously sampled samples or impurities remain inside the sampler, they may contaminate subsequent samples, leading to inaccurate test results. This contamination is particularly significant when sampling trace substances. To ensure the normal operation of the sampler, regular manual cleaning and maintenance are required. This not only increases the workload of operators but may also be inconvenient or impossible to perform in some field environments, thus affecting the sampler's lifespan and performance. Therefore, a portable aerosol sampler is proposed to address these issues. Utility Model Content

Rotating gear three is connected to the rotating motor, not only providing assistance for the motor's operation but also driving rotating gear two, which is coaxial with it, to rotate synchronously. Rotating gear two then drives rotating gear four, which engages with the sliding rack to convert circular motion into linear motion, causing the sliding support block to slide smoothly.

A self-cleaning mechanism 2 is fixedly connected to the outside of the protective shell 1, and a fixing mechanism 3 is fixedly connected to the inside of the protective shell 1. The self-cleaning mechanism 2 includes a rotating gear 202, and a cleaning assembly 2011 for cleaning is fixedly connected to the output end of the rotating gear 202. The cleaning assembly 2011 includes a sliding support block 206, which plays a key role in supporting and connecting other components. A sliding connecting plate 208 is fixedly connected to the outside of the sliding support block 206, transmitting the movement of the sliding support block 206 to the cleaning flexible brush 209, and simultaneously cleaning the cleaning flexible brush 209. The sliding support block 206 serves to fix and support the cleaning brush 209, ensuring its stability during sliding. The cleaning brush 209 is fixedly connected to the outside of the sliding connecting plate 208 to perform cleaning tasks. Its soft material efficiently removes particles, dust, and other impurities adhering to the protective shell 1 without damaging its surface. Sliding racks 207 are fixedly connected to both sides of the sliding support block 206, meshing with the rotating gear 4 205. This converts the circular motion of the rotating gear 4 205 into its own linear motion, thereby driving the sliding support block 206 to slide linearly, realizing the reciprocating cleaning action of the cleaning component 2011. A support connecting block 2010 is fixedly connected to the outside of block 206. This connects the sliding support block 206 and the sliding connecting plate 208, ensuring their coordination during movement. The support connecting block 2010 is slidably connected to the outside of the sliding connecting plate 208. A rotating gear 3 204 is fixedly connected to the outside of rotating gear 1 202, receiving the power transmitted from rotating gear 1 202 and meshing with rotating motor 201 to provide power for its operation. A rotating gear 203 is rotatably connected to the outside of support connecting block 2010, receiving the power transmitted from rotating gear 3 204 and transmitting it to rotating gear 4 205. The self-cleaning mechanism 2 is rotatably connected to the support connecting block 2010 to ensure its stability during operation. Rotary gear 203 is externally rotatably connected to rotary gear 4 205, which meshes with sliding rack 207. Rotary motor 201 is externally rotatably connected to the support connecting block 2010 to provide stable power output for the continuous operation of the entire self-cleaning mechanism 2. Rotary motor 201 is externally rotatably connected to the outside of rotary gear 4 205. Rotary gear 4 205 and sliding rack 207 are meshed with each other. Rotary gear 3 204 and rotary motor 201 are meshed with each other. Rotary gear 3 204 and rotary gear 203 are meshed with each other.
[0033] Reference Figure 1 , Figure 2 and Figure 4The fixing mechanism 3 includes a rotating connecting column 301, which, through an externally applied rotational force, drives the connecting fixing block 302 fixedly connected to it to rotate. The connecting fixing block 302 is fixedly connected to the outside of the rotating connecting column 301, and its main function is to transmit the rotation of the rotating connecting column 301 to the rotating connecting block 303. Two rotating connecting blocks 303 are fixedly connected to the outside of the connecting fixing block 302, rotating under the drive of the connecting fixing block 302. Their inner sides are rotatably connected to the second fixed connecting block 306, and their outer sides are slidably connected to the fixed support block 304. The inner side of the rotating connecting block 303 is rotatably connected to the second fixed connecting block 306, serving a connecting and supporting function. Its outer side is fixedly connected to the fixing column 307 and the first fixed connecting block 305, thus fixing the entire fixing mechanism 3. The fixed connecting block 306 is securely connected to the protective shell 1. A fixed connecting post 307 is fixedly connected to the outside of the fixed connecting block 306 to securely fix the fixed connecting block 306 inside the protective shell 1. Two fixed connecting blocks 305 are fixedly connected to the outside of the fixed connecting block 306 to assist in the connection between the fixed connecting block 306 and the protective shell 1. Two fixed support blocks 304 are fixedly connected to the outside of the fixed connecting block 306 to provide a sliding track for the rotating connecting block 303. When the rotating connecting block 303 rotates under the drive of the fixed connecting block 302, it slides along the track of the fixed support block 304. The rotating connecting block 303 is slidably connected to the outside of the fixed support block 304. The fixed connecting post 307 is fixedly connected inside the protective shell 1, and the fixed connecting block 306 is fixedly connected to the outside of the protective shell 1.
[0034] Working principle: When rotating gear 1 202 starts running, it drives rotating gear 3 204 to rotate, which in turn drives rotating motor 201 and rotating gear 2 203 to rotate, which in turn drives rotating gear 4 205 to rotate, which in turn drives sliding rack 207 and sliding support block 206 to rotate, which in turn drives sliding connecting plate 208 and cleaning flexible brush 209 to slide, thereby achieving the cleaning effect.
[0035] When the rotating connecting column 301 drives the connecting fixing block 302 to start rotating, it drives the rotating connecting block 303 to rotate. At the same time, the rotating connecting block 303 rotates inside the fixing connecting block 306, thereby driving the rotating connecting block 303 to rotate to the position of the fixing support block 304, thus achieving the effect of fixing.
