Description

Technical Field

[0001] The utility model relates to the technical field of equipment, in particular to an air quality sensor structure. Background Art

[0002] Air quality sensors, also called comprehensive air environment monitors, are commonly used in air purifiers and fresh air systems to detect air temperature, humidity, air pressure, light, PM2.5, PM10, TVOC and other values, as well as gas concentrations of oxygen O2, carbon dioxide (CO2), carbon monoxide (CO), formaldehyde (CH2O), etc. Existing air quality sensors are often directly installed on the walls of the testing site for easy measurement. When used in harsh environments, impurities or large particles are easily accumulated on the detection head, which in turn affects the detection accuracy.

[0003] Publication No. CN 218033565 U proposes an installation structure of an air quality sensor, including an installation base plate, installation screw holes, a shell installation slot, an elastic column, a pressure plate, a lower baffle, a shell mounting frame, a fixed plug plate, a filter installation slot, a filter, a shell, a heat dissipation window, and a front cover; the installation screw holes are arranged at the four corners of the installation base plate; the shell installation slot is installed on the installation base plate and is located on the inner side of the installation screw hole; the elastic column is installed on the installation base plate and is located on the inner side of the shell installation slot; the pressure plate is installed on the elastic column; the lower baffle is installed on the installation base plate and is located between the elastic columns; the fixed plug plate is installed on the inner side of the shell mounting frame and is inserted into the shell installation slot during installation. The device is inconvenient to disassemble and install during use, so the maintenance cost is high, and its interception effect on dust and moisture in the air is relatively limited, and it is difficult to meet the protection requirements of the sensor during long-term operation. To this end, we propose an air quality sensor structure. Utility Model Content

A bend pipe 24 is arranged inside the filter block 21 as a channel for air flow. When the air flows through the channel, the dust, impurities and moisture in the air flow can be filtered under the action of the filter screen 26 and the dehumidification cloth strip 27 respectively arranged in the two bending areas of the bend pipe 24. The air flow enters the bend pipe 24 through the connector 25, and after purification, it enters the shell 11 and contacts the sensor, so as to achieve the purpose of monitoring the air quality. When the sensor needs to be disassembled and maintained, the insertion rod 17 is pulled outward so that the limit block 16 is withdrawn from the slot 15 to complete the disassembly process of the shell 11 and the sensor body 12, so as to achieve the purpose of facilitating the maintenance of the equipment.
