Problems solved by technology

[0003] At present, for the detection of indoor air on the market, hand-held detectors are mostly used. This type of detection equipment has the advantages of being portable and easy to use. When in use, the display will display the current air quality by triggering the buttons on the detector. , but this type of detector cannot realize real-time detection and tracking, and after this type of detector is used, it is often placed without a fixed location, and it is not easy to find. The most important thing is that the environment where it is placed is unpredictable
At the same time, the above-mentioned handheld detector is limited by the volume of the device, so that it cannot be integrated with multiple sensors, which makes the detection of the device relatively one-sided, affecting the accuracy and comprehensiveness of the device for air detection

Embodiment 1

[0039] Such as Figure 1 to Figure 6 As shown, in this embodiment, the detection air duct 200 is divided into a lower air duct 204 and an upper air duct 203, the bottom of the lower air duct 204 is provided with a temperature and humidity sensor 1, and the lower air duct 204 is provided with CO sensors 2 and CO 2 The sensor 3 and the formaldehyde sensor 4 are equipped with a PM2.5 sensor 5 and a fan 6 in the upper air duct 203. Through the above arrangement, the sensors are installed in independent spaces, so that they will not affect each other during the detection process, and the detection stability and accuracy are improved.

[0040] In this embodiment, the lower air duct 204 is provided with two partitions arranged in parallel at intervals, namely the left partition 210 and the right partition 211; the two partitions divide the lower air duct 204 into three independent branches. The three branch air channels are: the first branch air channel 218 formed by the gap between the...

Embodiment 2

[0044] Such as Figure 1 to Figure 6 As shown, in this embodiment, the detection air duct 200 includes a vertically extending cylindrical air duct shell 205, and the bottom of the cylindrical air duct shell 205 is provided with a lower baffle 209 installed with a temperature and humidity sensor 1. The baffle 209 is provided with an air inlet 201; the top of the cylindrical air duct shell 205 is provided with an upper baffle 208, and the upper baffle 208 is provided with an air outlet 202.

[0045] In this embodiment, the cylindrical air duct shell 205 is provided with an inner air duct shell 206, the inner air duct shell 206 is located on the upper part of the cylindrical air duct shell 205, and the inner air duct shell 206 encloses an independent upper air duct 203 At the same time, the inner air duct shell 206 constitutes the overall shell of the PM2.5 sensor 5 and the fan 6, and the inner air duct shell 206 is detachably installed in the air duct shell 205.

Abstract

The invention relates to a detection air duct of indoor air environment monitoring equipment.The vertically-extending detection air duct is arranged in a shell of the indoor air environment monitoring equipment.An air inlet is formed in the lower end of the detection air duct, and an air outlet is formed in the upper end of the detection air duct.A fan for providing power for detection airflow flowing from bottom to top is installed in the detection air duct.A sensor set for detecting detection airflow is also arranged in the detection air duct.According to the arrangement, the sensor set composed of six sensors comprising a temperature and humidity sensor, a CO sensor, a CO2 sensor, a formaldehyde sensor, a PM2.5 sensor and the like is installed in the detection air duct in an integration mode, detection of the sensors is not affected, and comprehensive detection of indoor airflow is achieved; meanwhile, the detection air duct is simple in structure, remarkable in effect and suitable for being used and popularized.

Description

Technical field [0001] The invention belongs to the field of detection equipment components, and specifically relates to a detection air duct of indoor air environment monitoring equipment. Background technique [0002] In recent years, air pollution has become more and more serious, and regional air pollution has become more prominent. Haze affects people's travel. Fine particle pollution such as PM2.5 has attracted widespread public concern. The composition of outdoor pollutants is complex, and the indoor gas pollution has also changed from traditional formaldehyde, carbon monoxide and other harmful gases to gas-solid comprehensive pollution caused by formaldehyde, carbon monoxide, and PM2.5 particulate matter. People are concerned about the surrounding office and life. Attention to the air quality in the environment is also increasing. [0003] At present, for indoor air detection on the market, handheld detectors are mostly used. This type of detection equipment has the advant...
