Problems solved by technology
In recent years, the problem of air pollution has become more and more serious, especially the concentration data of fine suspended particles (such as PM2. Indeterminate flow, and most of the air quality monitoring stations that detect suspended particles are fixed points, so it is impossible to confirm the concentration of suspended particles in the surrounding area at all. Therefore, a miniature and portable gas detection device is needed for users to monitor at any time and any place. Detect the concentration of aerosols around

A particle detection module comprises a base, a detection part and a micro pump. The base is provided with a micro pump bearing area, a detection part bearing area and a gas guide channel. The detection part is arranged in a containing compartment of the detection part bearing area, comprises a particle sensor and a laser emitter, and is used for detecting the size and concentration of suspended particles contained in the gas. The micro pump is carried in the micro pump bearing area. A gas guide path is formed in the particle detection module, the micro pump is driven and controlled to draw and transmit gas in the gas guide path, and the gas can be quickly guided into the gas guide path, so that the detection part detects the size and concentration of suspended particles contained in the gas.
Description
technical field [0001] This case relates to a particle detection module, especially a particle detection module that can be assembled in a thin portable device for gas monitoring. Background technique [0002] Suspended particles refer to solid particles or liquid droplets contained in the air. Because of their very fine particle size, they can easily enter the lungs of the human body through the nasal hairs in the nasal cavity, thus causing lung inflammation, asthma or cardiovascular disease. If other Pollutants attached to suspended particles will aggravate the harm to the respiratory system. In recent years, the problem of air pollution has become more and more serious, especially the concentration data of fine suspended particles (such as PM2. Indeterminate flow, and most of the air quality monitoring stations that detect suspended particles are fixed points, so it is impossible to confirm the concentration of suspended particles in the surrounding area at all. Therefor...
