Utility Model Content

A smoke purifier is provided that can sense smoke and automatically switch on and off.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] The utility model describes a smoke purifier capable of sensing an automatic smoke switch, comprising a purifier body and a telescopic tube; the upper entrance end of the purifier body is connected and fixedly connected with the telescopic tube; the upper end of the telescopic tube is connected and fixedly connected with a three-way pipe; the two ends of the three-way pipe are connected and fixedly connected with a bellows; the lower end of the bellows is sleeved with an external plate; a center pin is inserted in the external plate; a suspended plate is sleeved on the center pin; a smoke sensor is fixedly connected to the suspended plate; a suspended positioning unit is provided on the external plate.

[0013] 1. The utility model is electrically connected to the purifier body through the smoke sensor, and the purifier body can be started for adsorption after the smoke sensor detects a certain concentration of welding smoke.
