Abstract
Description
Technical Field
[0001] The utility model relates to the field of negative ion detectors, in particular to a handheld negative ion detector. Background Art
[0002] At present, the detection of negative ions in the air mainly relies on negative ion detectors. In the existing negative ion detectors, an air intake duct and an exhaust fan are arranged inside the casing. The exhaust fan is located at one end of the air intake duct inside the casing, and the other end of the air intake duct extends out of the casing. The exhaust fan is opposite to one end of the air intake duct, and the components in the detection air duct are energized to keep different parts of the probe component polarized. The exhaust fan draws external air into the air intake duct, allowing the probe component to receive the negative ions introduced into the air duct, thereby measuring the concentration of negative ions in the air. However, since a negative ion detector with this structure requires a narrow and long air intake duct and an exhaust fan, the overall structure of the negative ion detector is relatively large and difficult to miniaturize. In particular, the air intake duct occupies a large space in the detector and is not conducive to the structural arrangement in the detector. Therefore, a handheld negative ion detector is urgently needed to solve the above problems. Utility Model Content
