Air detection device, air sampling device and air sampling method

空气检测装置、其空气采样装置及方法

Abstract

The invention relates to an air detection device, an air sampling device and an air sampling method. The air sampling device comprises a housing, the top and the bottom of the housing are respectively provided with pores, a VOC sensor and a particle sampling unit are arranged in the housing and the VOC sensor is provided with a heating unit. The air detection device comprises the air sampling device and a signal processing device for computing a corresponding detection result according to the sampling result. The air sampling method is realized based on the air sampling device and comprises applying heating voltage for the VOC sensor so that the VOC sensor has a detection temperature, heating the VOC sensor and simultaneously carrying out thermal convection of air currents so that air enters into the housing by the pores and is respectively collected by the VOC sensor and the particle sampling unit. The air sampling device has a small volume and a low cost and realizes sampling of air particles and VOC.
本发明涉及空气检测装置、其空气采样装置及方法,该空气采样装置包括壳体,壳体的顶部和底部分别设置气孔,壳体内设置VOC传感器和颗粒物采样单元,所述VOC传感器具有加热元件。该空气检测装置它包括上述空气采样装置和用于根据采样结果计算相应检测结果的信号处理装置。该空气采样方法基于上述空气采样装置实现,包括给VOC传感器施加加热电压使VOC传感器达到检测温度,对VOC传感器的加热同时使空气产生热对流,使环境空气经所述气孔进入所述壳体内,从而分别被VOC传感器和颗粒物采样单元采样。本采样装置体积小、成本低,且能够同时采样空气颗粒物和VOC。
