The range hood products on the market are generally of an upper fan 12 and a lower smoking structure, wherein the range hood products are divided into a top suction type and a near suction type. For the top-suction type range hood, a user can generate a large amount of oil smoke during quick frying, the suction effect of the top-suction type range hood is better than that of a near-suction type range hood, but the oil smoke is easy to contact with a human face, the generated oil smoke is smaller when the user carries out ordinary frying, and the suction effect on a small amount of oil smoke is not ideal as the suction structure of the top-suction type range hood is far away from a gas stove; to nearly inhaling formula smoke ventilator, the oil smoke that the user produced can be smaller when ordinary stir-fry, and the smoke ventilator can be inhaled and discharged cleanly, but when stir-fry, can produce a large amount of oil smoke, will have a lot of oil smoke to outwards loss this moment, and smoke exhaust effect is not obvious. To this problem, this disclosure provides a novel smoke ventilator.

Specifically, the first supporting rod 91 is installed at two sides of the main smoke barrier 32 in the main body case 11, and is used for connecting and supporting the main smoke barrier 32; the push rod motor 6 can be arranged on the upper host shell 11, and when the push rod motor 6 works, the push rod is controlled to do telescopic linear motion; the lower air inlet 31 is provided with a main smoke baffle 32 and side smoke baffles 33 positioned at two sides of the main smoke baffle 32, the side surface of the main smoke baffle 32 is arranged at the upper part of the lower air inlet 31 through a rotating shaft, the main smoke baffle 32 can rotate around the rotating shaft, and the maximum rotating angle is 45 degrees when the main smoke baffle 32 is opened; the main smoke baffle 32 is provided with a second support rod 92 and is connected with the first support rod 91 through the second support rod 92; the main smoke baffle 32 is provided with a rotary supporting structure 8, and the rotary supporting structure 8 is connected with the movable end of a push rod in the push rod motor 6 through a connecting rod 7; the left side and the right side of the main smoke baffle 32 are provided with side smoke baffles 33, one end of each side smoke baffle 33 is arranged on the shell of the lower machine body 3, the other end of each side smoke baffle 33 is arranged on the main smoke baffle 32, and when the main smoke baffle 32 is closed, the side smoke baffles 33 are folded towards the direction close to the main smoke baffle 32; when the main smoke barrier 32 is opened, the lower air inlet 31 is in a cover suction mode; when the main smoke baffle 32 is closed, the lower air inlet 31 is in a suction mode; when the range hood is in a shutdown state, the push rod motor 6 controls the push rod to return (initial position), and the side smoke baffle 33 is in a folded state; when the range hood is started, the push rod motor 6 works, the push rod extends and moves linearly to drive the connecting rod 7 to move forwards, the connecting rod 7 drives the main smoke baffle 32 to rotate through the rotating support structure 8, meanwhile, the side smoke baffle 33 is opened, and the range hood stops when the main smoke baffle 32 rotates by 45 degrees; when the range hood is closed, the push rod motor 6 moves, the push rod is shortened and moves linearly, the connecting rod 7 is driven to contract, the main smoke baffle 32 starts to rotate, and meanwhile, the side smoke baffle 33 is folded until the main smoke baffle 32 returns to the initial state.

The smoke ventilator in this disclosure can set up three kinds of mode, is respectively: the cooking mode includes a normal cooking mode, a stir-frying mode and a ventilation mode, in the normal cooking mode, the main smoke barrier 32 is closed (as shown in fig. 18-19), but because the lower air inlet 31 is still partially exposed outside the main smoke barrier 32, the oil smoke mainly enters the interior of the range hood from the lower air inlet 31 (corresponding to a near-suction mode), and at this time, part of the oil smoke can also enter the interior of the range hood through the upper air inlet 21 and then is discharged out of the room through the fan 12. In the stir-fry mode, the main smoke baffle 32 is opened (as shown in fig. 13 and 22-23), the oil smoke mainly enters the interior of the range hood through the lower air inlet 31 (equivalent to a cover suction mode), at the moment, part of the oil smoke can also enter the interior of the range hood through the upper air inlet 21 and is discharged out of the room through the fan 12, specifically, the push rod motor 6 works, the push rod extends and moves linearly to drive the connecting rod 7 to move forwards, the connecting rod 7 drives the rotary supporting structure 8 to rotate so as to drive the main smoke baffle 32 to rotate, meanwhile, the side smoke baffle 33 is opened, when the main smoke baffle 32 rotates 45 degrees, the oil smoke stops, and the oil smoke enters the range hood through the lower air inlet 31 and is discharged out of the room through the fan 12; after the user closes the range hood, the push rod motor 6 moves, the push rod is shortened and moves linearly to drive the connecting rod 7 to contract, the connecting rod 7 drives the rotating support structure 8 to rotate so as to drive the main smoke baffle 32 to start rotating, and meanwhile, the side smoke baffle 33 is folded until the main smoke baffle 32 returns to the initial state; in the ventilation mode, the working state of the kitchen air purification equipment can be the same as that of a common cooking mode and can also be the same as that of a stir-frying mode.

It should be noted that the main smoke barrier 32 in the present disclosure may be rotated to any angle and fixed at the angle, and the angle of the above-mentioned stir-fry mode may be 45 degrees, for example only, or 30 degrees, etc., and the angle may also be automatically selected according to the preference of the user, which is not limited by the present disclosure.
