When the telescopic panel 1 moves in the telescopic inner cavity a, it drives the driven gear 13 to roll along the second rack a2 for guidance. The second rack a2 is arranged on both sides of the first rack a1. The driven gear 13 meshing with the second rack a2 is arranged on the telescopic panel 1, so that the telescopic panel 1 can move smoothly when moving in the telescopic inner cavity a.

[0033] In other embodiments of the telescopic panel assembly, a second rack a2 is laid on the bottom plate of the telescopic inner cavity a, and the second rack a2 and the first rack a1 are symmetrically arranged on the bottom plate of the telescopic inner cavity a. A driven gear 13 meshing with the second rack a2 is provided on the telescopic panel 1, and the driven gear 13 is rotatably connected to the telescopic panel 1. In this embodiment, the telescopic panel 1 is driven in a manner similar to the above-mentioned embodiment, and the driven gear 13 is driven by the telescopic panel 1 in a manner similar to the above-mentioned embodiment, except that there is only one second rack a2, and the second rack a2 and the first rack a1 are symmetrically arranged on the bottom plate of the telescopic inner cavity a. The cooperation of the second rack a2 and the driven wheel 13 can still guide the telescopic panel 1, so that the telescopic panel 1 moves smoothly in the telescopic inner cavity a.

[0036] In other embodiments of the telescopic panel assembly, a driven shaft is provided on the telescopic panel 1, and a driven gear 13 is rotatably connected to the driven shaft.

The driving gear 12 slides along the first rack a1 and drives the telescopic panel 1 to move in the telescopic inner cavity a. The telescopic panel 1 applies a force toward or away from the telescopic inner cavity a to the slide bar 32. Under this force, the slide bar 32 moves toward or extends out of the telescopic inner cavity a along the slide 31, thereby driving the telescopic panel 1 to retract or extend out of the telescopic inner cavity. And under the guiding action of the guide assembly 3, the friction between the telescopic panel 1 and the telescopic inner cavity a becomes smaller, and the telescopic panel 1 moves more smoothly when extending or retracting the telescopic inner cavity a.

The wind curtain assembly is started, the wind curtain assembly draws air through the wind curtain suction port 14, and exhausts air downward through the wind curtain outlet 15 to form a wind curtain. The PM2.5 detection module draws air through the detection air hole 16 to detect the PM2.5 concentration in the air to feedback the purification effect of the range hood on the oil fume when the range hood is working. The lighting assembly transmits light downward through the lighting window 17, which is convenient for users to observe the ingredients being cooked. After the user completes the cooking operation, the air curtain assembly is closed, the PM2.5 detection module is turned off, the lighting assembly is turned off, and the driving member 2 drives the telescopic panel 1 to retract into the telescopic inner cavity a. After the telescopic panel 1 is completely retracted into the telescopic inner cavity a, the driving member 2 stops moving.

[0042] See also Figures 3 to 5 In the range hood of the present invention, the detection air hole 16 is arranged on the upper surface of the telescopic panel 1. The air entering the detection air hole 16 is the air above the telescopic panel 1. When the air curtain assembly is started and the smoke exhaust fan of the range hood is started, the air quality above the telescopic panel 1 represents the purification of the oil fume by the range hood and the escape of the oil fume. When the result detected by the PM2.5 detection module meets the standard, it indicates that there is no oil fume escape. When the result detected by the PM2.5 detection module does not meet the standard, it indicates that there is oil fume escape.
