[0002] The air quality sensor built into the touch screen is a technical product that combines efficient interaction with precise monitoring, and it has demonstrated significant technical advantages in the fields of smart home and environmental monitoring. From the perspective of the technical environment, touch screen technology has developed to a fairly mature stage, especially in capacitive touch technology, which has the characteristics of high sensitivity, high reliability and durability, and can provide users with a smooth operating experience. At the same time, air sensor technology is also constantly improving, from single gas monitoring to the development of all-in-one sensors, which not only improves monitoring accuracy, but also broadens the scope of application.

[0003] However, in the existing combination of touch screen and sensor, there are still some shortcomings and defects, as follows: 1. The sensor is installed in the touch screen housing. After long-term use, a lot of dust will usually accumulate inside the housing. The accumulation of dust will affect the heat dissipation and detection of the sensor. Therefore, it is generally necessary to regularly remove the dust and clean the inside of the housing, which means that the whole machine needs to be disassembled first, and then the back cover is removed by removing the screws for cleaning. In addition, when the software used in conjunction with the sensor is upgraded, it is also necessary to remove the back cover to expose the internal sensor module before upgrading. The whole process is cumbersome and complicated, which increases the difficulty and cost of maintenance; 2. The touch screen and the sensor are installed in the same space. First, the temperature generated when the touch screen is working will affect the detection accuracy of the sensor. Utility Model Content
