Description

Technical Field

[0002] With the remarkable improvement of living standards, residents' attention to indoor air quality has reached an unprecedented level; however, the problem of air pollution cannot be ignored, and pollutants such as formaldehyde, PM2.5, and TVOC constantly threaten our health. In order to meet the needs of the general public for accurate air quality detection, a multifunctional air quality detector is thus required.

[0003] Regarding the existing multifunctional air quality detectors, the detection probes of most detectors are fixed in position, making it difficult to detect the air quality of different height layers according to actual detection needs, resulting in limited detection ranges, unable to comprehensively and accurately obtain air quality data, and difficult to meet the needs of diverse detection scenarios; on the other hand, after the detector completes an air detection, if it immediately detects the air of the next height layer, dust and other impurities from the previous air layer are likely to remain on the surface of the detection probe, and these impurities will affect the accuracy of subsequent detection results. Moreover, the existing detectors lack an effective automatic cleaning mechanism, and manual cleaning of the probe is required frequently, which not only makes the operation cumbersome but also increases the detection cost and time. In addition, during the idle or movement of the detection probe of the detector, it is easily bumped by external objects and eroded by dust, and the existing protective measures are often not perfect enough to effectively protect the detection probe, resulting in the sensitivity and service life of the probe being affected, and further affecting the performance and reliability of the entire detector.

The sliders 503 at the inner ends of the first guard plate 501 and the second guard plate 502 are respectively slidably installed on the outer guide grooves 205 at the outer ends of the movable seat 2, so as to drive the first guard plate 501 and the second guard plate 502 to automatically move outward at the same time through the rotating shaft 206. Similarly, when the inner control panel 3 of the device is retracted inward, the first guard plate 501 and the second guard plate 502 are automatically moved inward at the same time to automatically protect the detection probe 6 of the device, so that the device has better linkage and protection effect, and avoids the detection probe 6 being easily bumped and dust falling when stored nakedly, which affects the detection effect of the detection probe 6 of the device.

[0044] Specific usage method and function of this embodiment: In the present invention, the motor 101 drives the adjustment screw 103 to rotate, so as to drive the moving seat 2 to move outwards. The guide blocks 302 at the front and rear ends of the inner control board 3 are slidably installed on the inner guide grooves 202 inside the moving seat 2. The first clamping plate 104 is fixedly installed at the rear end of the chain 4, and the second clamping plate 301 is fixedly installed at the front end of the chain 4. When the moving seat 2 moves outwards, the position of the first clamping plate 104 remains stationary, so as to drive the second clamping plate 301 and the inner control board 3 to automatically extend outwards in a secondary manner through the sprocket 203, thereby enabling the device to have better extensibility and being able to detect the air quality of different height layers, improving the adjustability of the device; when the moving seat 2 moves outwards, it drives the runner 303 to rotate, so as to drive the cleaning block on the moving frame 304 to move left and right reciprocally. Thus, when the device adjusts the detection at different heights, the cleaning block on the moving frame 304 can automatically wipe and clean the surface of the detection probe 6, avoiding the problem that the detection probe 6 of the device may detect the air layer at the next height immediately after the detection is completed, and the dust and the like on the surface of the detection probe 6 remaining from the previous air layer are likely to cause detection errors. Therefore, the device has a better cleaning effect and improves the detection accuracy of the device; when the inner control board 3 extends outwards, it drives the rotating shaft 206 to rotate, so as to drive the first protection plate 501 and the second protection plate 502 to automatically move outwards simultaneously through the rotating shaft 206. Similarly, when the inner control board 3 of the device retracts inwards, the first protection plate 501 and the second protection plate 502 automatically move inwards simultaneously to automatically protect the detection probe 6 of the device, enabling the device to have better linkage and protection effects, and avoiding the detection effect of the detection probe 6 of the device being affected by bumps and dust.
