Switching assembly of gas stove

A switching assembly of a gas stove, comprising:

• a regulating valve having a valve member and a regulating member, wherein the regulating member is received in the valve member, and rotatable to regulate a gas flow through the valve member;
• a shaft having an end connected to the regulating member;
• a knob connected to an opposite end of the shaft to be turned to rotate the regulating member;
• a stop board located between the valve member of the regulating valve and the knob, wherein the stop has a curved slot, which has a first stop portion, a second stop portion, and a third stop portion;
• and
• a restricting device connected to the knob and engaged in the curved slot of the stop board, wherein the restricting device is movable in the curved slot either between the second stop portion and the third stop portion, or between the first stop portion and the third stop portion;
• wherein the knob is turnable within a first internal if the restricting device is movable between the second stop portion and the third stop portion, and is turnable within a second internal if the restricting device is movable between the first stop portion and the third stop portion;
• wherein when the knob is turnable within the second interval, a maximum gas flow which the regulating valve is able to supply is larger than that when the knob is turnable within the first interval.
