Abstract

The invention provides a gas furnace timer driving circuit, which comprises a control circuit, a power supply voltage stabilizing circuit, a detection circuit, a sound production circuit, a display circuit and a motor driving circuit, and is characterized in that the control circuit is connected with the power supply voltage stabilizing circuit, the detection circuit, the sound production circuit, the display circuit and the motor driving circuit, the power supply voltage stabilizing circuit is connected with the detection circuit, the sound production circuit, the display circuit and the motor driving circuit, the detection circuit comprises a travel switch detection circuit, the travel switch detection circuit is used for detecting the set position of a gas furnace knob, and the motor driving circuit is used for driving a motor to rotate and controlling the rotating position of the gas furnace knob. According to the invention, a travel switch detection circuit is adopted, the influence on the knob force after installation is small, and the original knob force is not influenced; a motor driving circuit is adopted to drive a motor to rotate, the rotating position of the gas furnace knob is controlled, and the gas closing function is achieved; and the gas furnace timer driving circuit solves the problems that an existing gas stove timer is high in cost, large in force for rotating a knob by hand and inconvenient to use.

Description

technical field [0001] The invention relates to the technical field of drive circuits, in particular to a gas stove timer drive circuit. Background technique [0002] When using a gas stove, you may burn the kitchen utensils or even cause a fire because you forget to turn off the gas stove. The gas furnace timer is installed at the position of the gas furnace knob, and the countdown can be set in advance. After the predetermined countdown is completed through the internal circuit and motor mechanism, the gas furnace knob is automatically turned to close the gas furnace, which can minimize accidents. [0003] At present, there is a class of products on the market that is a simple timing alarm without the function of shutting down the gas. There is a type that has the function of turning off the gas, but after installation, the strength of the gas stove knob is greatly increased, which affects the use and is expensive. Contents of the invention [0004] In order to overcom...
