[0065] Through the above design, in the embodiment, the oil extractor is generally arranged below the ceiling and has a certain interval from the user, the gesture recognition switch 21 can enable the user to directly realize the turning on and off of the whole oil extractor through human gestures without directly contacting the whole machine, which is convenient and fast in daily use, and when the human fingers are in a wet state, the gesture (it should be noted that since the hands of the person will pass below the oil extractor many times during cooking activities such as frying, the gesture here is specific to avoid misjudgment of the oil extractor) is used instead of the fingers to operate the switch, which avoids potential dangers such as electric shock and short circuit.

[0066] In the embodiment, the gesture recognition switch 21 mainly consists of two infrared sensors, which guarantees the function of gesture recognition. The infrared sensor is a common prior art, which will not be described here.

[0067] In the embodiment, the control panel 2 is further provided with a whole machine switch, a light adjustment switch and a light color adjustment switch (not shown in the figure), the whole machine switch can control the opening and closing of the whole machine, the light adjustment switch can control the light intensity of the color-changing lamp strip 5, and the light color adjustment switch can switch the light color of the color-changing lamp strip 5; the whole machine switch, the light adjustment switch and the light color adjustment switch are all physical switches, i.e. switches that need to be actually contacted to be operated, and can be used as another operation mode of the whole machine in addition to the gesture recognition switch 21, thereby providing more choices for the user in operation.

[0068] Specifically, as shown in the figure, Figure 7 The control panel 2 is further provided with a ring-shaped lamp 22, and the ring-shaped lamp 22 is electrically connected with the control panel 2 and the gesture recognition switch 21 respectively.
