Description

Technical Field

[0001] This application relates to the field of indoor air monitoring and purification technology, and more specifically, to air quality monitoring and purification devices. Background Technology

[0002] As people have increasingly higher requirements for the quality of their living environment, especially their indoor living environment, indoor decoration will emit formaldehyde gas for a long time. Combined with dust floating in the environment, inhaling it will affect and damage health. It is necessary to use air monitoring and purification devices to monitor and purify indoor air quality. Air purifiers can be installed indoors, but air purifiers are expensive, bulky, and take up a lot of indoor space, making them inconvenient to install. Air purifiers also cannot provide alarm functions for excessive indoor formaldehyde and dust levels. In view of this, we propose an air quality monitoring and purification device. Utility Model Content

[0003] 1. Technical problems to be solved

[0004] The purpose of this application is to provide an air quality monitoring and purification device that solves the technical problems mentioned in the background art. It achieves dust filtration and formaldehyde purification by using a built-in motor to rotate an impeller within an inner shell, drawing indoor air through an intake pipe and directing it into the exhaust chamber of the outer shell. The purified air is then monitored for dust and formaldehyde content using sensors, and finally discharged into the room through an end cap, achieving the goal of indoor air purification. The device is lightweight and easy to assemble and disassemble, and can be wall-mounted using two elastic clips on the power supply base. Furthermore, when the monitoring results exceed preset values, the device triggers an alarm, reminding personnel to replace the activated carbon particles and formaldehyde purification particles in a timely manner.
