The bottom cover 21 and the bottom of the shell 23 are fixedly connected and sealed by buckles. The shell 23 passes through the switch hole of the gas stove panel 5 and is fixed on the gas stove panel 5 by threaded connection with the locking nut 24. The rotating shaft 22 is arranged in the shell 23. The top of the rotating shaft 22 passes through the locking nut 24 and the shell 23 and is fixedly connected to the linkage switch knob 25 by buckles. The bottom of the rotating shaft 22 is fixedly provided with a rotating shaft 22 contact piece, and the rotating shaft 22 contact piece is a good conductive The two ends of the contact piece of the rotating shaft 22 and the contact piece of the housing 23 are arranged in a semicircular shape. The contact piece of the rotating shaft 22 abuts against the inner wall of the housing 23. The contact piece of the housing 23 is embedded on the inner wall of the bottom of the housing 23. The contact piece of the housing 23 is a metal sheet with good conductivity. The contact piece of the housing 23 includes a long contact piece 27 and three short contact pieces 28. The long contact piece 27 is connected to the live wire (L) of the power supply. The short contact piece 28 is respectively connected to each gear of the range hood motor. The setting of the linkage opening gear corresponds to the setting of the gear of the gas stove knob 1. The larger the flame, the greater the wind force of the range hood. The linkage switch knob 25 drives the contact piece of the rotating shaft 22 to rotate, connect the range hood drive motor circuit, and rotate at different angles to connect different gears of the range hood motor.

[0026] A lever 41 is provided on the upper end surface of the linkage switch knob 25, and an arc-shaped long groove 42 capable of accommodating the lever 41 is provided in the inner cavity of the gas stove knob 1, the arc-shaped long groove 42 has a central angle of 180°, and the counterclockwise starting end of the arc-shaped long groove 42 corresponds to the position of the lever 41. When the gas stove knob 1 is pressed down to ignite the gas stove, the counterclockwise starting end of the arc-shaped long groove 42 covers the lever 41, driving the linkage switch knob 25 to rotate together, turning on the gas stove to adjust the flame and turning on the range hood to adjust the wind force; when the linkage switch 2 has already turned on the range hood, the lever 41 is located in the middle section of the arc-shaped long groove 42 when the gas stove knob 1 is pressed down to ignite, and will not hinder the pressing down of the gas stove knob 1 to ignite. When the counterclockwise starting end of the arc-shaped long groove 42 meets the lever 41, it will rotate with the linkage switch knob 25. At the same time, the lever 41 can also play a role in indicating the gear position of the range hood.

[0027] Two first limit blocks 291 are symmetrically provided on the inner wall of the housing 23, and a second limit block 292 is provided on the outer wall of the rotating shaft 22.

[0028] The angle at which the second limit block 292 can rotate between the two first limit blocks 291 is consistent with the center angle of the arc-shaped long groove 42. The center angles of several short contact pieces 28 from the first to the last are consistent with the center angle of the long contact piece 27. The center angle of the arc-shaped long groove 42 is slightly larger than the center angle of the long contact piece 27 to leave a blank position.

[0029] When in use, the gas stove knob 1 is pressed down to ignite and the range hood is turned on at the same time. The gas stove knob 1 is rotated counterclockwise to adjust the flame and at the same time drives the linkage switch 2 to rotate counterclockwise to adjust the range hood gear. After adjusting the flame size, the gas stove knob 1 is released, and the gas stove knob 1 rises and disengages from the linkage switch 2. The two can adjust the gas stove and the range hood separately without interfering with each other. When the gas stove is not turned on, the range hood can be turned on and off and adjusted by rotating the linkage switch knob 25 alone. When the linkage switch 2 has already turned on the range hood, when the gas stove knob 1 is pressed down to ignite, the lever 41 is located in the middle section of the arc-shaped long groove 42, which will not hinder the pressing down of the gas stove knob 1 to ignite. When the counterclockwise starting end of the arc-shaped long groove 42 meets the lever 41, it will rotate together with the linkage switch knob 25.

[0030] When in use, it can ensure that the range hood is turned on simultaneously with the gas stove in one action, without hindering the independent operation of the range hood and the gas stove, which is convenient and efficient.
