Description

technical field

[0001] The invention relates to a special power cord, especially a power cord with a gas induction device. technical background

[0002] Existing air exhaust equipment, such as range hoods, exhaust fans, etc., uses a power cord consisting of a single-phase three-wire plug and a wire electrically connected to it, and its function is to transmit single-phase three-wire alternating current to the electrical appliance body circuit. The gas induction controller installed on the range hood is arranged on the range hood body. Such as commercially available: Jinbaili CXW-200-228A, Shuaikang CXW-180-2388, Yuli CXW-180-2000K, etc., which have the function of automatically starting the pumping unit and sound and light warning when it senses the leakage of gas . But it has the following disadvantages: 1. The gas sensor is relatively close to the stove and is easily stuck by oily smoke, which reduces the sensitivity or fails, and loses its pr...
