Description

Multi-fan negative ion sensor

Technical Field

The utility model relates to the technical field of ion detection equipment, in particular to a multi-fan anion sensor.

Background

The negative ion sensor can be applied to equipment such as an ion detector. In use, air must flow through the ion collection chamber (e.g., the polarization tube). Normally, the greater the air flow through the ion collection chamber, the more accurate the measurement. Most of the existing negative ion sensors utilize a fan to make air flow through an ion collection chamber. In order to increase the air flow, the air flow can only be increased by increasing the rotation speed of the fan. Because the rotating speed of the fan is increased, the noise of the fan is increased, the wind noise is correspondingly increased, and the noise is increased on the whole. For ordinary users (such as home users), noise of the sensor is an important index, and too much noise is pollution for the users (such as the noise is great to cause discomfort when the sensor is used at home), and a negative ion sensor which can increase air flow and does not increase noise is needed.
