Description

Technical Field

[0001] This utility model relates to the technical field of air quality detection and analysis equipment, specifically to an air quality detection and analysis device. Background Technology

[0002] In the field of air quality monitoring, various testing and analysis devices are widely used in indoor and outdoor environmental monitoring, industrial production environment assessment, and other scenarios. These devices typically require continuous intake of air samples for analysis, and to ensure testing accuracy, filters are usually installed at the air inlet to filter out impurities and particles in the air.

[0003] However, traditional air quality monitoring equipment presents numerous inconveniences in practical use. On the one hand, because the equipment is often installed at high locations (such as high on walls or at the top of supports), impurities easily accumulate on the filters after long-term use. If not cleaned in time, this will affect air circulation efficiency and lead to deviations in the test data. However, the existing equipment's filter cleaning methods have obvious defects: some equipment requires manual cleaning at heights, which is not only cumbersome and difficult but also poses a safety hazard of falling from heights; other equipment, although equipped with simple cleaning structures, is unable to deal with stubborn stains, and the parts that collect impurities are also inconvenient to clean, resulting in incomplete cleaning and affecting the continuous and stable operation of the equipment.

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.

[0023] Example 1

[0024] like Figures 1-3 As shown, an air quality detection and analysis device includes an air quality detection and analysis device body 12 and an air intake frame 14. A vertical column 11 is fixedly provided at the bottom of the air quality detection and analysis device body 12, and a chassis 1 is fixedly provided at the bottom of the vertical column 11. An air intake pipe is provided on one side of the air quality detection and analysis device body 12, and the air intake pipe is connected to the air intake frame 14. A connecting block 22 is slidably provided on one side of the vertical column 11, and a horizontal bar 21 is fixedly provided on one side of the connecting block 22. A column 23 is fixedly provided at one end of the top of the horizontal bar 21, and a horizontal plate 24 is fixedly provided at the top of the column 23. A filter screen 37 and a collection box 39 are fixedly provided at the top of the horizontal plate 24. A first through groove 141 and a second through groove 142 are opened at the bottom of the air intake frame 14. The filter screen 37 and the collection box 39 are respectively movably inserted into the first through groove 141 and the second through groove 142. The top of the inner cavity of the air intake frame 14 is fixedly provided with a vertical plate 17, and the collection box 39 is located between the filter screen 37 and the vertical plate 17. A scraper 36 is rotatably provided on one side of the vertical plate 17.

[0025] A square box 171 is fixedly provided on the other side of the vertical plate 17. A first bevel gear 33 is rotatably provided on the top inner wall of the square box 171. A rotating column 34 is rotatably provided on the other side of the vertical plate 17. One end of the rotating column 34 passes through the square box 171 and a second bevel gear 35 is fixedly provided at its end. The first bevel gear 33 and the second bevel gear 35 are meshed and connected. The other end of the rotating column 34 passes through the vertical plate 17 and is fixedly connected to the scraper 36.

[0026] A placement box 15 is fixedly provided on the top of the air intake frame 14, and a motor 31 is fixedly provided inside the placement box 15. The output shaft of the motor 31 passes through the air intake frame 14 and is fixedly connected to the first bevel gear 33.

[0027] Working principle: When in use, this solution realizes the function of air detection and analysis through the air quality detection and analysis equipment body 12. Its overall structure is supported and fixed by the vertical column 11 and the chassis 1.

[0028] During testing, air enters the equipment through the air intake frame 14 on one side of the air quality detection and analysis equipment body 12. The filter 37 installed inside the air intake frame 14 can filter the incoming air and remove impurities and particles from the air.

[0029] When impurities accumulate on the surface of the filter screen 37 and need to be cleaned, the motor 31 inside the placement box 15 is started. The motor 31 drives the first bevel gear 33 to rotate. Through the meshing transmission between the first bevel gear 33 and the second bevel gear 35, the rotating column 34 and the scraper 36 fixed at its end are driven to rotate. The scraper 36 contacts the surface of the filter screen 37 and can scrape the impurities on the filter screen into the collection box 39, thereby realizing the automatic cleaning of the filter screen 37.

[0030] When it is necessary to remove the filter screen 37 and the collection box 39 for cleaning and replacement, slide the connecting block 22 downward to pull the filter screen 37 and the collection box 39 out of the first through groove 141 and the second through groove 142 of the air intake frame 14; during installation, slide the connecting block 22 to insert the filter screen 37 and the collection box 39 into the corresponding through groove, and achieve initial fixation through the magnetic attraction of the first magnet 19 and the second magnet 241.

[0031] Example 2

[0032] In this embodiment, in order to enhance the connection strength between the horizontal plate 24 and the suction frame 14, a first magnet 19 is fixedly provided at the bottom of the suction frame 14 with a first through groove 141 and a second through groove 142 symmetrically distributed, and a second magnet 241 corresponding to the first magnet 19 is fixedly provided at the top of the horizontal plate 24. The first magnet 19 and the second magnet 241 are magnetically attracted to each other.

[0033] Example 3

[0034] In this embodiment, a rubber block 38 is fixedly provided at the bottom of the filter screen 37, and a rubber pad is fixedly provided on the outer wall of the collection box 39. The rubber block 38 at the bottom of the filter screen 37 and the rubber pad on the outer wall of the collection box 39 can enhance the sealing after installation and ensure the air filtration and impurity collection effect.

[0035] Example 4

[0036] In this embodiment, in order to facilitate the sliding and fixing of the connecting block 22, a slider 221 is fixedly provided on the side of the connecting block 22 facing the vertical column 11. A groove 111 is provided on the outer wall of the vertical column 11, and the slider 221 is slidably installed in the groove 111 to facilitate the sliding of the connecting block 22.

[0037] The outer wall of the vertical column 11 is fixed with a fastening block 16. The front and rear ends of the fastening block 16 are screwed with screws 161, which are screwed into the connecting block 22 to facilitate the installation and disassembly of the connecting block 22.

[0038] Both the connecting block 22 and the fastening block 16 are C-shaped blocks. After the connecting block 22 and the fastening block 16 are connected to each other, they are fitted onto the outside of the vertical column 11.

[0039] When the filter screen 37 and the collection box 39 need to be removed, loosen the screw 161 on the fastening block 16, slide the connecting block 22 downward, and pull the filter screen 37 and the collection box 39 out of the first through groove 141 and the second through groove 142 of the suction frame 14. During installation, slide the connecting block 22 to insert the filter screen 37 and the collection box 39 into the corresponding through groove. The first magnet 19 and the second magnet 241 are used to achieve initial fixation. Then tighten the screw 161 to complete the positioning.

[0040] Example 5

[0041] In this embodiment, a sunshade 13 is fixedly installed on the top of the air quality detection and analysis equipment body 12. The sunshade 13 can provide sun protection.

[0042] Example 6

[0043] In this embodiment, to further improve the reliability and durability of the equipment transmission mechanism, rotary sealing rings are provided at the rotational connection between the rotating column 34 and the square box 171, and at the rotational connection between the output shaft of the motor 31 and the square box 171. These sealing rings are tightly fitted around the outer periphery of the rotating column 34 and the motor output shaft, forming a dynamic sealing structure with the inner wall of the corresponding through hole of the square box 171. The two sealing rings can always maintain a tight fit with the rotating parts, effectively preventing impurities in the suction frame 14, such as dust and particles intercepted by the filter screen 37, from entering the interior of the square box 171. This avoids impurities adhering to the tooth surfaces or meshing points of the first bevel gear 33 and the second bevel gear 35, preventing gear wear from being aggravated, transmission from jamming, or even failure due to impurities. This ensures the long-term stable operation of the bevel gear transmission mechanism, reduces the frequency of equipment maintenance, and extends its service life.

[0044] It should be noted and understood that various modifications and improvements can be made to the present invention as described in the above description without departing from the spirit and scope of the claims. Therefore, the scope of the claimed technical solutions is not limited to any specific exemplary teachings given.
