Title:
DEVICE STRUCTURE AND AIR PURIFIER
Document Type and Number:
WIPO Patent Application WO/2018/233406
Kind Code:
A1
Abstract:
A device structure and an air purifier, the device structure comprising a gas-sensitive resistor (1), a heating wire (2), and a catalytic material layer (3). The gas-sensitive resistor (1) is connected in series with the heating wire (2). The catalytic material layer (3) is wrapped around the heating wire (2). Resistance of the gas-sensitive resistor (1) increases as concentration of a specified gas decreases, such that when the concentration of the specified gas decreases, the heating temperature of the heating wire (2) acting on the catalytic material layer (3) lowers, slowing down the catalytic reaction speed of the catalytic material layer (3) acting on the specified gas. The device structure of the invention controls the catalytic reaction speed of the catalytic material layer according to the concentration of the specified gas, such that removal of the specified gas is ensured, and consumption of the catalytic material of the catalytic material layer is reduced, lowering usage costs.
