Air purifier capable of sensing formaldehyde concentration and performing sterilization and formaldehyde removal in time

Abstract

The invention provides an air purifier capable of sensing formaldehyde concentration and performing sterilization and formaldehyde removal in time, and relates to the technical field of air purifiers.The air purifier capable of sensing the formaldehyde concentration and performing sterilization and formaldehyde removal in time comprises a base; a machine body shell is fixedly connected to the topof the base; a ventilation pipe is fixedly connected to the top of the machine body shell; and a spring rod is fixedly connected to the end, away from a rotating shaft, of a connecting rod. The spring rod is driven to extrude a stress plate through rotation of the rotating shaft, an electromagnet is powered on to drive a gear to rotate through cooperative use of a rotating block and a rotating ring, and through cooperative use of the gear and a toothed bar, when the air intake is increased, a guide column drives an activated carbon box to move, so that more activated carbon is exposed, and the effect of purifying formaldehyde in time is achieved; and a formaldehyde tester in the machine body shell is driven to move through rotation of the rotating shaft, so that the effect of detecting the concentration of the formaldehyde in air is achieved.

Description

technical field [0001] The invention relates to the technical field of air purifiers, in particular to an air purifier that can sense formaldehyde concentration and sterilize and remove formaldehyde in time. Background technique [0002] Formaldehyde mainly comes from indoor decoration and decoration materials. Many harmful substances that do not participate in the reaction remaining in the sheet materials will gradually be released to the surrounding environment with the air, forming the main formaldehyde in the indoor air. Use an air purifier to absorb formaldehyde in the room, but the traditional air purifier is always in operation. When the air intake is increased, it cannot be purified in time, making the work efficiency relatively low, and the traditional purifier cannot Check whether the formaldehyde in the air is purified. [0003] In order to solve the above problems, the inventor provides an air purifier that can sense the concentration of formaldehyde and sterili...
