Refrigerator sticker with smoke detection function

Abstract

The invention discloses a refrigerator sticker with a smoke detection function. The refrigerator sticker comprises a substrate, a decorating board and an absorption board, wherein a PCB (printed circuit board) and a smoke detection sensor are arranged on the substrate; the PCB is electrically connected with the smoke detection sensor; the smoke detection sensor is used for sensing an external smoke content; the decorating board is arranged on the front surface of the substrate; the absorption board is arranged on the back surface of the substrate; a vacuum chuck is arranged on the absorption board to achieve absorption; a slide groove and a slide block are formed and arranged on the side edge of the substrate; the slide block is connected with the slide groove in a sliding manner; the smoke detection sensor is fixedly mounted on the slide block; the a plurality of electromagnets are arranged in different positions of the slide groove of the substrate; a permanent magnet is arranged inthe slide block; the electromagnets are electrically connected with the PCB; and the PCB is used for controlling polarity of any one or more of the electromagnets. The smoke detection sensor can detect the smoke content in the multiple positions movably, and the detection precision is ensured.

Description

technical field [0001] The invention relates to the field of daily necessities, in particular to a refrigerator magnet with smoke detection function. Background technique [0002] Refrigerators have become an indispensable household appliance in our lives. Refrigerator magnets are one of the common daily necessities of people. They are attached to the outer side of the refrigerator or the door panel of the refrigerator through magnetic sheets to play a decorative role. [0003] Existing refrigerator magnets are mostly made of resin or pottery into a certain three-dimensional shape, such as vegetables, animals, etc., which are single in variety, poor in decorative effect, poor in practicability, and old in style. [0004] Not only that, refrigerators are usually placed in the kitchen now, and people often forget to turn on the exhaust fan when cooking. When the smoke in the kitchen exceeds a certain level, it will cause serious harm to the human body. Therefore, a refrigerato...
