When the oil cup 60 needs to be cleaned, the two hands respectively press the buttons 621 on the two sides to detach the oil cup 60.

In this embodiment, the transmission lever set preferably includes a first transmission lever 623 and a second transmission lever 624, the first transmission lever 623 is L-shaped, one end of the first transmission lever 623 is connected to the button 621, the other end of the first transmission lever 623 has a first wedge surface, one end of the second transmission lever 624 is connected to the buckle 625, the other end of the second transmission lever 624 has a second wedge surface, and the first wedge surface and the second wedge surface are in sliding fit. When pressing button 621, button 621 upward movement compresses first reset spring 622, promotes first wedge face upward movement simultaneously, because of first wedge face and second wedge face are the inclined plane contact, so the second wedge face can backward movement to drive buckle 625 rearward movement compresses second reset spring 626 simultaneously.

In this embodiment, preferably, a first positioning portion is disposed in the mounting groove, the first driving rod 623 is slidably disposed through the first positioning portion, and the first return spring 622 is sleeved on the first driving rod 623 and located between the button 621 and the first positioning portion. A second positioning portion is further disposed in the mounting groove, the buckle 625 is slidably disposed through the second positioning portion, and the second return spring 626 is sleeved on the buckle 625 and located between the second positioning portion and the hook portion 6251.

Further, the embodiment of the utility model provides a range hood still includes oil mass detection device, and oil mass detection device is used for detecting the oily volume of collection in oil cup body 61, and oil mass detection device is connected with the alarm device communication. When the collected oil weight in the oil cup 60 reaches a set value, the oil amount detection device controls the alarm device to give an alarm through the electric control signal so as to prompt a user to clean the oil cup 60, so that the oil cup 60 is cleaned in time, and the overflow of oil is avoided.

In this embodiment, referring to fig. 20, the oil amount detecting device is a gravity sensor 90, the gravity sensor 90 is disposed in the slot, when the hook portion 6251 is engaged with the slot, the hook portion 6251 can be supported by the gravity sensor 90, and when the gravity sensor 90 detects that the weight of the oil cup 60 reaches a set weight, it indicates that the oil amount is full, and the oil cup 60 needs to be cleaned. Or the oil mass detection device can also be for including buoyancy ball and sensor, and buoyancy ball sets up in oil cup body 61, and the sensor is used for detecting the height of buoyancy ball, and when the sensor detected that buoyancy ball reached and set for the height, then it was full to explain the oil mass, needs clear up oil cup 60.
