Heat insulation rotary knob and gas stove therewith

The invention discloses a heat insulation rotary knob and a gas stove therewith. The heat insulation rotary knob includes a rotary knob body and a heat insulation sleeve that slidably sleeves the rotary knob body between a first position and a second position. At the first position of the heat insulation sleeve, the upper end of the rotary knob body is accommodated inside the heat insulation sleeve; and at the second position of the heat insulation sleeve, the upper end of the rotary knob body is stretched out from the heat insulation sleeve. According to the embodiment, by arranging the slidable heat insulation sleeve on the rotary knob body, when the rotary knob body is subjected to thermal radiation and is fired, the rotary knob body can be coated with the heat insulation sleeve so as to prevent heat from continuously radiating the rotary knob body, which increases the temperature of the rotary knob body. When a user is to use the rotary knob, the rotary knob body is exposed of theheat insulation sleeve th
