Abstract

A premixer and a gas device. The premixer includes a premixer body, a gas distribution member, an adjustment shaft and a gas regulator. The premixer body has a gas channel. The gas distribution member is at least partially provided in the gas channel, and is provided with a first gas distribution hole and a second gas distribution hole respectively communicating with the gas channel. The figure formed by the first gas distribution hole and the figure formed by the second gas distribution hole are non-congruent figures. The gas regulator is provided at the adjustment shaft and located in the gas channel. The gas regulator can rotate synchronously with the adjustment shaft and rotate to completely or partially unblock or block the first gas distribution hole and/or the second gas distribution hole, to adjust the gas flow area of the first gas distribution hole and/or the second gas distribution hole.
