Optionally, the first housing may be directly fixed to the outer wall of the first air outlet channel 111 by using fasteners such as screws, or the first housing may be mounted on a fixing bracket, and the fixing bracket is fixedly connected to the outer wall of the first air outlet channel 111 by using fasteners such as screws, and the mounting manner of the electromagnetic valve 31 is not specifically limited in the embodiment of the present application.

Further, the diameter of the first flow passage 1113 is smaller than that of the second flow passage 1114, so that when the second flow passage 1114 is opened from the closed state, the gas flow can be obviously increased.

It should be noted that the first flow channel 1113 may be in a conducting state all the time, that is, no matter whether the first electromagnetic valve 31 is actuated or not, the gas entering the first gas outlet channel 111 may pass through the first flow channel 1113 all the time and enter the second gas outlet section 1112, and the second gas outlet section 1112 faces the burner of the gas stove, and the conducting of the second flow channel 1114 increases the ventilation cross section between the first gas outlet section 1111 and the second gas outlet section 1112, thereby increasing the gas flow rate instantaneously.

Since the burner of the gas range can be a multi-ring structure, the gas outlet pipeline 11 of the gas valve needs to have a plurality of gas outlet channels opposite to each fire ring of the burner, so that the gas outlet pipeline 11 is provided with one or more other gas outlet channels in addition to the first gas outlet channel 111.
