Abstract

The invention discloses an air door adjusting device and a gas stove. The air door adjusting device comprises a driving motor, and an air door module is in gear connection with the driving motor; andthe driving motor drives the openness of the air door module through gear transmission to adjust the air feeding quantity. Through adjustment of the openness of the air door module through gear transmission, the openness adjustment of the air door is more precise, the mixing ratio of gas of the gas stove and air is more reasonable, and the combustion efficiency of the gas is improved.

Description

technical field [0001] The invention belongs to the field of household gas cookers, and in particular relates to a damper adjusting device and a gas cooker. Background technique [0002] In the prior art, the damper plays a very important role in the gas stove, and is used to adjust the mixing ratio of gas and air, so that the gas can be burned more fully. The existing dampers are all adjusted by mechanical dampers. The teeth are meshed and driven by a spur gear perpendicular to it, and then adjusted by a flexible shaft. Although the control knob of this adjustment method can be placed on the side of the gas stove, due to the flexible shaft transmission, the transmission speed will be affected. In the case of instability and torsional rigidity cannot be guaranteed, the adjustment of the damper cannot be precisely positioned and adjusted. [0003] The Chinese patent with the application number CN201521034451.3 discloses a gas stove with an electric adjustable damper, includi...
