In this embodiment, the smoke inlet of the range hood main body 1 is disposed below the smoke collecting hood 12. The oil smoke below the smoke collecting hood 12 is mainly sucked by the smoke inlet, that is, is mainly discharged to the outside by the oil smoke suction duct. The oil smoke escaping upwards from the edge of the smoke-collecting hood 12 is mainly sucked and processed by the air inlet 21a of the purifying shell 21. The purifying shell 21 is positioned on the front side of the fan cover 11, so that the air inlet 21a of the purifying shell 21 is arranged relatively more forward, and the oil smoke escaping to the breathing area of the user can be sucked into the purifying shell 21 more favorably, so that the oil smoke in the breathing area of the user is reduced, and the harm of the oil smoke to the health of the user is further reduced.

Generally, the cigarette maker main body 1 is provided with a control panel located on the front of the smoke collecting hood 12, and when the cigarette maker main body 1 and the air cleaning device 2 share one control switch 4, the control switch 4 is generally integrated on the control panel, that is, the control switch 4 is located on the front of the smoke collecting hood 12, which may be more convenient for a user to operate.

Optionally, a purge shell 21 is provided at the lower portion of the front face of the fan guard 11; it can be understood that the lower portion of the front surface of the fan guard 11 is closer to the user breathing area, that is, the air inlet 21a of the purifying housing 21 is closer to the user breathing area, which is more favorable for sucking and purifying the oil smoke escaping to the user breathing area, and can be more favorable for improving the air quality of the user breathing area. However, the design is not limited to this, in some other embodiments, the purifying housing 21 may also be disposed on the upper portion of the front surface of the fan housing 11, so that the position of the purifying housing 21 is higher, and the position of the air outlet 21b is higher, so that the purified air blown out from the air outlet 21b can be blown to a higher space in the kitchen, and therefore, the oil smoke close to the ceiling of the kitchen can be pushed by the purified air to flow downward, and the range of air circulation purification in the kitchen is wider, and the purification is more thorough. In other embodiments, the purifying housing 21 can be disposed in the middle of the front surface of the fan guard 11, so as to improve the air quality in the breathing zone of the user and to increase the range of air circulation purification in the kitchen to some extent.

Optionally, the purifying housing 21 is detachably mounted on the cigarette machine body 1, and may be, but is not limited to, mounted on the cigarette machine body 1 by using one or more detachable structures such as screw locking structures, snap structures, etc. to facilitate the maintenance and disassembly of the air purifying device 2. Further optionally, the front lower portion, middle portion and upper portion of the fan guard 11 are respectively provided with a detachable mounting position for selectively mounting the purifying housing 21, so that the user can conveniently change the upper and lower positions of the air purifying device 2 according to different air purifying requirements.

The above only is the preferred embodiment of the present invention, not limiting the scope of the present invention, all the equivalent structure changes made by the contents of the specification and the drawings under the inventive concept of the present invention, or the direct/indirect application in other related technical fields are included in the patent protection scope of the present invention.
