Indoor air quality detection device and comprehensive index detection system thereof

Abstract

An indoor air quality detection device disclosed by the present invention comprises a detector, an air inlet and air outlets, the air inlet is located at the lower end of the detector, the air outlets are located on the outer surface of the periphery of the detector, the detector is of a T-shaped structure design, and an air inlet cavity is formed in the position, close to the lower side, of the outer surface of the rear end of the detector. A sealing plate is hinged to the rear end of the air inlet cavity, a filtering assembly is arranged in the air inlet cavity, the air inlet cavity is communicated with the air inlet and the air outlet, the filtering assembly comprises two groups of cylindrical cavities, a driving roller, a driven roller and a filtering membrane, and the cylindrical cavities are symmetrically distributed left and right by taking the center of the air inlet cavity as a midpoint; a driving roller and a driven roller are sequentially arranged in the two groups of cylindrical cavities from right to left, a filter membrane is fixedly connected between the driving roller and the driven roller, and the width of the filter membrane is equal to that of the air inlet cavity; the air quality detector is installed at the top of a classroom, the occupied space can be reduced, meanwhile, unnecessary damage to the air quality detector caused by operation of the air quality detector by low-grade students can be prevented, and the filter membrane is automatically replaced under the action of the filter assembly.

Description

technical field [0001] The invention relates to the field of air quality detection, in particular to an indoor air quality detection device and a comprehensive index detection system thereof. Background technique [0002] With the development of society, people have higher and higher requirements for air quality, especially the air quality of schools where children study. In order to improve the air quality of classrooms, most schools often choose to install air quality detectors inside classrooms. Monitor classroom air quality. [0003] 1. The air quality detector in the prior art has a certain air purification ability, but in actual use, it takes up a lot of space inside the classroom, and facing the curiosity of junior students, it often leads to abnormal damage to the detector. Thus increasing the construction cost; 2. Due to the small classroom space and the large flow of people, the dust inside the classroom is relatively large, so the air quality detectors inside the...

[0003] 1. The air quality detector in the prior art has a certain air purification ability, but in actual use, it takes up a lot of space inside the classroom, and facing the curiosity of junior students, it often leads to abnormal damage to the detector. Thus increasing the construction cost; 2. Due to the small classroom space and the large flow of people, the dust inside the classroom is relatively large, so the air quality detectors inside the classroom need to be cleaned and maintained frequently. Therefore, it is particularly important to propose an air quality detector that can automatically replace the filter membrane.
