In some preferred implementations, the rotating motor can be a main motor of the range hood, the inner oil net 1 is driven by the main motor of the range hood, and an additional motor is not needed, so that the structure of the range hood is simplified, and the production cost is reduced.
In other embodiments, the motor 4 may also be implemented as a vibration motor, when the range hood performs range hood operation, the vibration motor drives the inner oil screen 1 to vibrate at high frequency to intercept grease particles in the range hood, and the vibration motor may be implemented by a conventional vibration motor in the prior art. In one exemplary implementation, the vibration motor frequency is 600Hz, the amplitude is 2mm, while achieving a grease hold-up efficiency of 90% or more.
In some embodiments, the heating device 2 may be implemented as an electric heating structure, such as one or more of a PTC heating sheet, a heating wire, and an electric heating tube. For example, in some embodiments shown in fig. 1-3, the heating device 2 is disposed outside the range hood at a position just inside the inner oil net 1, the heating device 2 is preferably a PTC heating sheet, the area of the PTC heating sheet is larger than that of the inner oil net 1, and when the range hood performs a cleaning operation, the PTC heating sheet heats the entire inner oil net 1 to liquefy grease and oil stains attached to the inner oil net 1.
In other embodiments, the heating device 2 may be implemented as a hot air heating device 21, and the hot air heating device 21 includes a fan and an air outlet 22 connected to the fan for heating the internal oil mesh 1. The fan can be arranged in the cigarette machine or in an external structure, and can also be independently used as an assembly structure to be matched with the cigarette machine, and the present disclosure does not limit the structure. The air outlet 22 may be located on the interior of the machine or on an external structure of the machine.

Because the melting points of common edible oil are not high, for example, the melting point of soybean oil is about 20 ℃, the melting point of palm oil is 22-42 ℃, the melting point of mutton fat is 40-55 ℃, the melting point of peanut oil is generally 3-5 ℃, and the melting point of sunflower oil is 17-27 ℃, theoretically, the temperature of about 60 ℃ is enough to liquefy grease and oil stains attached to the inner oil net 1, but actually, as the attached grease and oil stains have certain viscosity, dust in air is attached to the surface of the grease to form a dust layer, and experimental data show that the temperature of 60 ℃ is not enough to liquefy the attached grease and oil stains, the preset heating temperature of the temperature controller is set to be more than 75 ℃, and the cleaning effect on the oil stains is better.
In the above-described embodiment, the heating device 2 may further include an overheat protection device for overheat protecting the heating device 2. In an exemplary implementation, the overheating protection device can be implemented as a thermal fuse type safety device, preferably, the overheating protection temperature is 169 ℃, and the product is a safety device quite common in the prior art, and the disclosure is not repeated.
In still other embodiments, the heating device 2 may also be implemented as a flame heating device 23 for cleaning the internal oil mesh 1 by gasifying or carbonizing the grease on the internal oil mesh 1 by spraying a flame toward the internal oil mesh 1. The flame heating device 23 may be disposed within the cigarette machine or external structure, or may be implemented in connection with a separate external structure, which is not limited by the present disclosure. For example, in some embodiments shown in fig. 7, the flame heating device 23 comprises a gas tank 9 arranged in the range hood and a combustion port 2424 connected with the gas tank 9 for heating the inner oil net 1, as shown in fig. 7, the combustion port 24 is arranged at one side of the inner oil net 1, and during the process that the combustion port 24 sprays flame at one side of the inner oil net 1, the inner oil net 1 is slowly rotated under the driving of a rotating motor, so that the grease on the inner oil net 1 is fully carbonized and gasified, and therefore, the grease is separated from the inner oil net 1.
Preferably, in the above embodiment, after the heating device 2 heats the inner oil net 1, the inner oil net 1 is driven by the motor 4 to operate so as to accelerate the separation of the grease from the inner oil net 1. In an exemplary implementation, after the hot air heating device 21 heats the inner oil net 1, the inner oil net 1 is driven by a rotating motor to rotate, so that the liquefied grease is separated out of the inner oil net 1 by using centrifugal force.
