Description

Technical Field

[0001] This utility model relates to the field of air detection technology, specifically to an air detection and collection device that is easy to clean. Background Technology

[0002] With the increasing importance of environmental monitoring, air quality testing, as a key component, places increasingly stringent demands on the performance of testing equipment. In various air quality testing scenarios, from urban air quality monitoring stations to industrial waste gas emission monitoring points, from indoor environmental testing to tracing specific pollution sources, accurately acquiring air samples and conducting reliable analysis is crucial. However, existing air quality testing equipment faces many challenges in practical applications.

[0003] The outer casing and internal structure of traditional data collection equipment are prone to accumulating dust during long-term use. For example, in dusty environments such as industrial plants, a large amount of dust will adhere to the surface of the fixed casing after the equipment has been running for a period of time. Once this dust mixes into the collected air sample, it will interfere with the air sampling instrument's detection of various indicators such as the concentration and composition of pollutants in the air. Tiny dust particles may be misjudged as suspended particulate matter in the air, or they may react chemically with other pollutants, changing the chemical properties of the sample, thus causing serious deviations in the test results and failing to accurately reflect the air quality.

[0023] 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.

[0024] Please see Figure 1-5This utility model provides a technical solution: an easy-to-clean air detection and collection device, including an air collector 1 and an adjustment component 3. The bottom of the adjustment component 3 is fixedly connected to the top of the air collector 1, and a cleaning component 2 is rotatably connected to the inner wall of the adjustment component 3. The cleaning component 2 includes an outer ring 25, the top of which is fixedly connected to a connecting block 22 via an outer post 24, and the bottom of the outer post 24 is fixedly connected to the top of the outer ring 25. The bottom of the connecting block 22 is fixedly connected to an inner ring 26 via an inner post 23, and the top of the inner post 23 is fixedly connected to the bottom of the connecting block 22. A fixing ring 21 is fixedly connected to the outer wall of the connecting block 22, and a bristle is fixedly connected to the outer wall of the outer ring 25. The brush 27 is fixedly connected to the bottom of the inner column 23 and the top of the inner ring 26, and the top of the outer column 24 is fixedly connected to the bottom of the connecting block 22. When the adjustment component 3 needs to be cleaned, the operator grasps the fixing ring 21 and drives the fixing ring 21 to slide up and down. The fixing ring 21 is fixed to the inner column 23 and the outer column 24 through the connecting block 22, which in turn drives the inner ring 26 on the inner column 23 and the outer ring 25 on the outer column 24 to slide up and down. The outer ring 25 is connected to the brush 27, and the inner ring 26 is connected to the bristles and fits against the inner and outer walls of the fixed shell 33. Thus, when the outer ring 25 and the inner ring 26 slide up and down, the inner and outer walls of the fixed shell 33 can be cleaned.

[0025] The adjustment assembly 3 includes a fixed shell 33, a windshield shell 32 rotatably connected to the inner wall of the fixed shell 33, a connecting frame 31 fixedly connected to the top of the windshield shell 32, a fixed disk 36 magnetically attracted to the bottom of the fixed shell 33 by a permanent magnet column 35, and the top of the permanent magnet column 35 is fixedly connected to the bottom of the fixed shell 33. A locking nut 34 is threadedly connected to the top of the fixed shell 33 by a stud, and the outer wall of the permanent magnet column 35 is magnetically attracted to the inner wall of the top of the fixed disk 36.

[0026] The bottom of the locking nut 34 is pressed and fixed to the top of the connecting frame 31. The inner wall of the fixed shell 33 is slidably connected to the outer wall of the inner column 23. The bottom of the fixed plate 36 is fixedly connected to the top of the air collector 1. The outer wall of the fixed shell 33 is slidably connected to the bristles on the outer wall of the outer ring 25. The inner wall of the fixed shell 33 is slidably connected to the outer wall of the brush 27. The fixed shell 33 serves as an external frame, providing protection and support for the internal components. Its top is threadedly connected to the locking nut 34 via a stud. Its bottom is magnetically attracted to the fixed plate 36 via a permanent magnet column 35. The windshield 32 can rotate on the inner wall of the fixed shell 33. The connecting frame 31 fixedly connected to its top cooperates with the locking nut 34 to adjust and fix the rotation angle of the windshield 32.

[0027] The device mainly consists of an air sampler 1, an adjustment component 3, and a cleaning component 2. These components work together to solve the problem of cleaning the equipment. The air sampler 1, as the core detection component, is responsible for detecting and analyzing various indicators of the collected air. The adjustment component 3 is located on top of the air sampler 1 and is fixedly connected to the top of the air sampler 1 via a fixing plate 36. It provides a basic platform for the installation and operation of the cleaning component 2 and also has an adjustment function, which can adjust the working state of the cleaning component 2 according to actual needs. The cleaning component 2 is rotatably connected to the inner wall of the fixing shell 33 of the adjustment component 3 via an inner ring 26, an inner column 23, a connecting block 22, and an outer column 24. During the operation of the device, it can slide to achieve cleaning of key parts inside the device.

[0028] The core structure of the adjustment component 3 includes a fixed shell 33, a windshield shell 32, a connecting frame 31, a locking nut 34, a permanent magnet column 35, and a fixed plate 36. The fixed shell 33 serves as an external frame, providing protection and support for the internal components. Its top is threadedly connected to the locking nut 34 via a stud, and its bottom is magnetically attracted to the fixed plate 36 via the permanent magnet column 35. The windshield shell 32 can rotate within the inner wall of the fixed shell 33. The connecting frame 31, which is fixedly connected to its top, cooperates with the locking nut 34 to adjust and fix the rotation angle of the windshield shell 32.

[0029] When it is necessary to adjust the working state of the adjustment component 3, first loosen the locking nut 34. At this time, the windshield 32 can rotate freely inside the fixed shell 33. According to the actual air intake requirements, rotate the windshield 32 to a suitable position to change the size of the gap between the windshield 32 and the fixed shell 33. After the adjustment is completed, tighten the locking nut 34 so that the bottom of the locking nut 34 is tightly pressed and fixed with the top of the connecting frame 31, thereby locking the windshield 32 at the set angle. In addition, the adjustment component 3 can be easily disassembled and installed by the magnetic attraction between the permanent magnet column 35 and the fixed plate 36, which facilitates the overall maintenance and cleaning of the equipment.

[0030] The cleaning component 2 mainly consists of an outer ring 25, an outer column 24, a connecting block 22, an inner column 23, an inner ring 26, a fixing ring 21, and a brush 27. The outer ring 25 is fixedly connected to the top of the connecting block 22 through the outer column 24, and the inner ring 26 is fixedly connected to the bottom of the connecting block 22 through the inner column 23. The fixing ring 21 is fixed to the outer wall of the connecting block 22 to enhance structural stability. The brush 27 is fixed to the outer wall of the outer ring 25, and the outer wall of the brush 27 slides in contact with the inner wall of the fixing shell 33.

[0031] During the operation of the air sampler 1, when the adjustment component 3 needs to be cleaned, the operator grasps the fixing ring 21 and moves it up and down repeatedly. The fixing ring 21 is fixed to the inner column 23 and the outer column 24 by the connecting block 22, which in turn causes the inner ring 26 on the inner column 23 and the outer ring 25 on the outer column 24 to move up and down repeatedly. The outer ring 25 is connected to a brush 27, and the inner ring 26 is connected to brush bristles, which are in contact with the inner and outer walls of the fixed shell 33. Thus, as the outer ring 25 and the inner ring 26 move up and down, the inner and outer walls of the fixed shell 33 can be cleaned, preventing the dust on the fixed shell 33 from affecting the air and thus affecting the detection results of the air sampler 1.
