[0002] With the acceleration of the industrialization process and the improvement of the urbanization level, air pollution has become a global environmental problem, causing serious impacts on human health and the ecological environment. Therefore, real-time and accurate monitoring of air quality has become an urgent need. At present, there are a variety of air quality detection devices on the market, but most of them have problems such as low detection accuracy, poor stability, and susceptibility to interference, making it difficult to meet people's needs for high-quality air quality detection. To solve the above problems, in recent years, air quality detection technology based on gas sensor arrays has received extensive attention. The gas sensor array combines multiple gas sensors with different selectivities to simultaneously detect multiple harmful gases (such as PM2.5, VOCs, NOx, etc.). Compared with traditional single gas sensors, gas sensor arrays have the advantages of a wide detection range, high sensitivity, and good stability.

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0019] Referring to the attached drawings of the specification Figures 1-4 , an air quality detection device based on a gas sensor, comprising an air quality detection device. A rotating rod 2 is fixedly connected to the bottom end of the air quality detection device. The bottom end of the rotating rod 2 is rotatably connected to a protection plate 3. A protection pad 4 is arranged on the surface of the protection plate 3. The protection pad 4 and the protection plate 3 cover the surface of the sensor of the air quality detection device. A second auxiliary fixing plate 7 is fixedly connected to the side of the protection plate 3. A second sliding groove 8 is formed on the surface of the second auxiliary fixing plate 7. An insertion block 9 is slidably connected inside the second sliding groove 8. A first auxiliary fixing plate 5 is fixedly connected to the side of the air quality detection device. A first sliding groove 6 is formed inside the first auxiliary fixing plate 5. The insertion block 9 is inserted inside the first sliding groove 6. When the air quality detection device is in use, due to the rotational connection relationship between the rotating rod 2 and the protection plate 3, the protection plate 3 can cover and protect the rotating rod 2. Then, the insertion block 9 slidably arranged inside the second auxiliary fixing plate 7 is used to limit the first sliding groove 6, thereby achieving the fixed state of the protection plate 3.

[0020] Then, one end of the insertion block 9 is fixedly connected to a pulling handle 10, and anti-slip patterns are arranged on the outer surface of the pulling handle 10; through this mechanism, the pulling handle 10 can be more conveniently pulled, achieving an anti-slip effect.

[0021] Subsequently, a first spring 11 is wound around the outer wall of the insertion block 9. One end of the first spring 11 is fixedly connected to the pulling handle 10, and the other end of the first spring 11 is fixedly connected to the second auxiliary fixing plate 7. The first spring 11 drives the insertion block 9 to insert into the first sliding groove 6 in the first auxiliary fixing plate 5 by using its own elastic performance, so that the device can be used normally.

[0022] Next, the second auxiliary fixing plate 7 and the first auxiliary fixing plate 5 are arranged in a stacked manner. Two groups of first sliding grooves 6 are provided on the first auxiliary fixing plate 5, and two groups of second sliding grooves 8 and insertion blocks 9 are provided on the second auxiliary fixing plate 7. Through this mechanism, the protection plate 3 can be fixed more stably at one end of the air quality detection device.

[0023] At this time, a sliding groove 12 is opened on the side of the protection pad 4, and a slider 13 is slidably connected inside the sliding groove 12. A cleaning pad 14 is fixedly connected to the outer end of the slider 13. Through this mechanism, the cleaning pad 14 slides the slider 13 through the sliding groove 12 to clean the surface of the protection pad 4 to a certain extent, so that the protection pad 4 will not cause dust to the air quality detection device during protection.

[0024] It should be noted that the cleaning pad 14 is in mutual contact with the surface of the protection pad 4. Through this structure, the dust-proof cover can be scraped more thoroughly by the cleaning pad 14 for the operator.

[0025] Finally, several points should be noted: First, in the description of the present application, it should be noted that unless otherwise specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense, which can be mechanical connection or electrical connection, or the communication inside two components, and can be directly connected. "Up", "down", "left", "right", etc. are only used to represent the relative position relationship. When the absolute position of the described object changes, the relative position relationship may change;

[0026] Second: In the attached drawings of the disclosed embodiments of the present utility model, only the structures related to the disclosed embodiments are involved. Other structures can refer to the general design. Without conflict, the same embodiment and different embodiments of the present utility model can be combined with each other;

[0027] Finally: The above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
