Problems solved by technology
Existing air detection methods use spectral analysis, ion mobility spectrometry, or absorption liquid absorption for detection. The cost of spectral analysis and ion mobility spectrometry detection equipment is high and is not suitable for large-scale applications. The absorption speed cannot be guaranteed, resulting in slow detection speed and poor accuracy, and is not suitable for real-time monitoring with a wide range

Provided in the invention is an air detecting device comprising a body. The body is provided with an air inlet and an exhaust port and is vertically arranged. A first piston and a second piston are arranged in the body from top to bottom; the two pistons divide the body into three cavities including an intake cavity, an isolation cavity and a pressurized cavity from top to bottom; the air inlet and the exhaust port are disposed at the top of the body and are communicated with the intake cavity. The two pistons are respectively provided with a first piston rod and a second piston rod in a matching manner; and the first piston rod is sleeved in the second piston and the second piston rod. A first liquid inlet and a first liquid discharge port are formed in the top surface of the first piston; a second liquid inlet and a second liquid discharge port are formed in the top surface of the second piston. All liquid inlets and liquid discharge ports are communicated externally through flow channels formed in all pistons and the piston rods. A hydraulic port is disposed at the bottom of the body and is communicated with the pressurized cavity. On the basis of the traditional absorption liquid measurement, the pressurizing function is added, so that the absorption speed is increased substantially; and the pressurizing function is realized by the hydraulic system and the pressure is relatively accurate.
Description
technical field [0001] The invention relates to a gas detection device, in particular to an air detection device. Background technique [0002] Nowadays, due to the gradual increase in safety requirements, air detection equipment is widely used in large offices or commercial places. Existing air detection methods use spectral analysis, ion mobility spectrometry, or absorption liquid absorption for detection. The cost of spectral analysis and ion mobility spectrometry detection equipment is high and is not suitable for large-scale applications. The absorption speed cannot be guaranteed, resulting in slow detection speed and poor accuracy, and is not suitable for real-time monitoring with a wide range. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the invention provides an air detection device with fast detection speed and high precision. [0004] The technical solution adopted in the present invention is: an air detection device, includin...
