Without loss of generality, an oil smoke suction air duct is arranged in the range hood main body 1, the smoke inlet is an oil smoke inlet communicated with the interior of the range hood air duct, and oil smoke entangled during cooking is sucked into the oil smoke suction air duct through the smoke inlet; the oil fume suction duct is also provided with a fume outlet communicated with the outdoor space so as to discharge the oil fume to the outdoor space; of course, the oil fume suction duct is internally provided with an oil fume fan for enabling the airflow to flow from the fume inlet to the fume outlet. It can be understood that the range hood main body 1 has the functions of the traditional range hood. Generally, the range hood main body 1 further includes a decorative cover 11 disposed above the smoke collecting hood 12, and the range hood duct is disposed inside the decorative cover 11.

The air purification device is internally provided with a purification air channel which is independent from the oil fume absorption air channel, the air outlet 201 is a purification air outlet of the purification air channel, the purification air channel is also provided with an air inlet, and the air outlet 201 and the air inlet are both communicated with the indoor space; it filters piece and purification fan to be equipped with in the purification wind channel, under purification fan's drive effect, the air intake is used for inhaling the indoor air in kitchen, filters the piece and is used for filtering the purification to the air of inhaling, air outlet 201 is used for discharging back the air after filtering purification in kitchen indoor.

When the air purification device and the cigarette machine main body 1 work cooperatively, most of oil smoke generated in the cooking process is discharged to the outside through the oil smoke suction air duct, a small part of oil smoke can escape to other spaces in a kitchen, and the small part of oil smoke can be further removed through the purification air duct of the air purification device, so that the pollution of the oil smoke to the air environment and the damage to the health of a human body are further reduced.

Optionally, the air purification device is arranged in the range hood main body 1, so that the appearance piece can be conveniently shared, and the appearance of the range hood is simpler. However, the design is not limited thereto, and in other embodiments, the air purification device may be disposed outside the cigarette maker main body 1, so as to facilitate maintenance and disassembly of internal devices (such as filter elements, purification fans, etc.).

As for the technical solution of disposing the air purification device in the cigarette machine body 1, optionally, the air purification device is disposed in the decoration cover 11, and the air outlet 201 thereof is exposed on the front surface of the decoration cover 11, so that the clean air purified by the air purification device can be sent out to the kitchen space.

Similarly, in other embodiments, the second rotating wheel 222a may also be replaced by a second driving motor, and the second driving motor is connected to the active vertical bar 221a in a driving manner, so as to achieve intelligent and automatic left-right adjustment of the air outlet direction of the air purifying device.

Generally, a grille frame 23 is disposed at the air outlet 201, the first air guiding grid 211 and the second air guiding grid 221 are both rotatably connected to the grille frame 23, the first rotating wheel 212a and the second rotating wheel 222a are both rotatably disposed on the grille frame 23, and both the first rotating wheel 212a and the second rotating wheel 222a are partially exposed outside the grille frame 23.

For the technical scheme that the air purification device is arranged in the cigarette machine main body 1, further, referring to fig. 1 and 5, the decoration cover 11 is provided with a filter mounting opening 111, and the filter is detachably mounted through the filter mounting opening 111; thus, the filter element can be conveniently detached, cleaned or replaced. It will be appreciated that the filter element generally has a certain life and needs to be replaced after its life has been reached in order to ensure good cleaning capacity of the air cleaning device, and that it can be removed periodically or aperiodically for cleaning or rinsing, which is advantageous in order to prolong its life.

Optionally, a filter cover 112 is disposed on the filter mounting opening 111; so, will filter the piece certainly filter a mounting hole 111 and pack into and purify the wind channel after, will filter a lid 112 lid and close and filter a mounting hole 111, can avoid filtering a piece and shake out, improve the structural stability of product, can also avoid foreign matter etc. to get into from filtering a piece installation simultaneously and purify in the wind channel.

Further optionally, the filter element is drawably arranged at the filter element mounting opening 111; it can be understood that the filter element can be more conveniently removed, cleaned or replaced by pulling.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, and all modifications and equivalents of the present invention, which are made by the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
