[0020] The specific implementation of a movable air curtain device for a gas stove provided by the present invention is further described in conjunction with the accompanying drawings and embodiments.

[0021] like Figure 1 As shown, a movable air curtain device for a gas stove includes a housing 1, and the inner cavity of the housing 1 is provided with a control system, an alarm device, a fan 3 and a drive motor 7. Specifically, the fan 3 is arranged at one end of the inner cavity of the housing 1, and the drive motor 7 is installed at the other end of the inner cavity of the housing 1. An air outlet is arranged at the top of the housing 1 along the length direction; an air guide plate 4 is rotatably installed at the edge along the length direction of the air outlet.

[0022] Preferably, both ends of the air guide plate 4 are provided with a rotating shaft 41 , and the housing 1 is provided with an axial hole corresponding to the position of the rotating shaft 41 ; the rotating shafts 41 at both ends of the air guide plate 4 are rotatably connected to the axial holes on both sides of the housing 1 .

[0023] like Figure 2As shown, a first gear 42 is provided at the bottom of the air guide plate 4 near the driving motor 7; a second gear 8 is sleeved on one end of the output shaft of the driving motor 7; wherein the first gear 42 is meshed with the second gear 8, and the angle between the air guide plate 4 and the air outlet is adjusted by controlling the rotation direction and rotation angle of the driving motor 7, thereby realizing the adjustment of the air outlet angle of the present invention, so as to achieve adaptation to various models of smoke extractors.

[0024] Preferably, a ventilation hole 2 is formed on the side wall of the housing 1 close to the fan 3 .

[0025] Preferably, a control panel 5 and a battery box 6 are installed on the outer side wall of the front end of the housing 1. The battery box 6 can realize independent power supply of the present invention, solving the problem of increased power consumption of the stove itself.

[0026] It is worth noting that a temperature sensor and a carbon monoxide concentration detector are also provided on the outer wall at the rear end of the shell 1, and both the temperature sensor and the carbon monoxide concentration detector are electrically connected to the alarm device; when it is detected that the area where the device is placed is too close to the fire and the surface temperature of the shell is too high or the carbon monoxide concentration is high, the alarm device will sound an alarm to remind the user. At the same time, the air output is increased to help disperse the carbon monoxide gas, thereby improving the safety of the user and avoiding safety hazards.

[0027] Further preferably, the alarm device, the fan 3, the control panel 5, the drive motor 7, the temperature sensor and the carbon monoxide concentration detector are all electrically connected to the control system.

[0028] When in use, the user only needs to place the invention under the corresponding area according to the position of the air outlet of the range hood, and adjust the angle of the air guide plate and the size of the air outlet by controlling the driving motor. The operation is simple, convenient and fast, and can effectively reduce the problem of oil smoke spreading during operation. At the same time, it can also avoid damage to the air curtain device caused by high temperature generated by the placement position too close to the fire or safety hazards caused by high concentration of carbon monoxide gas to the user himself.
