as shown in fig. 1 and 2, an automatic lifting range hood includes a fixing mechanism 1 and a lifting mechanism 2, the fixing mechanism 1 includes a fixed housing 11, a fan box disposed on a side surface of the fixed housing 11, and a first air duct 13 disposed in the fixed housing 11, a fan 12 is disposed in the fan box, the first air duct 13 is communicated with an air inlet of the fan 12, the lifting mechanism 2 includes a lifting assembly 21, the lifting assembly 21 includes a movable housing 211, a lifting driving member 212, and a lifting action member, the movable housing 211 is sleeved in the fixed housing 11 and fixedly connected with the lifting action member, a second air duct 214 is disposed in the movable housing 211, the second air duct 214 is communicated with the first air duct 13, an air inlet 224 is disposed on the movable housing 211, and the air inlet 224 is communicated with the second air duct 214;

the lifting mechanism 2 further comprises a turning component 22, the turning component 22 comprises a turning cover plate 223 and a rotating driving piece 221, the turning cover plate 223 is hinged to the upper portion of the movable shell 211, the rotating driving piece 221 is used for driving the turning cover plate 223 to rotate, the central axis of a rotating shaft of the turning cover plate 223, which is hinged to the movable shell 211, is perpendicular to the movement direction of the movable shell 211, and when the turning cover plate 223 is not attached to the movable shell 211, the turning cover plate 223 blocks oil smoke gas from flowing upwards so that the oil smoke gas is sucked from the air suction port 224; when the flip plate 223 is attached to the movable housing 211 and the movable housing 211 slides into the fixed housing 11, the flip plate 223 slides into the fixed housing 11 along with the movable housing 211.

As shown in fig. 2, 3 and 4, when the range hood needs to start working, the lifting driving member 212 drives the movable housing 211 to lift, and when the movable housing 211 rises to a certain height, the lifting stops. Then, the turning driving member 221 drives the turning cover plate 223 to turn, and the turning cover plate 223 is turned from a state of being attached to the movable housing 211 to a state of being perpendicular to the movable housing 211. When oil smoke gas with strong impact and rising force is generated on the cooker, the flip plate 223 prevents the oil smoke gas from rising upwards continuously, the flip plate 223 changes the movement direction of the oil smoke gas from vertical to horizontal, and the suction rate of the air suction port 224 to the oil smoke gas is improved.

As shown in fig. 2, 3 and 4, when the range hood is not required to work, the flip plate 223 is flipped downward until it is attached to the movable housing 211. In addition, in the process that the movable housing 211 slides downwards into the fixed housing 11, the flip plate 223 can slide into the fixed housing 11 along with the movable housing 211 to reset, and the range hood is attractive in appearance and small in occupied space.

As shown in fig. 1, an air suction plate 225 is fixed to the air suction port 224, the air suction plate 225 is provided toward the flap plate 223, and a rectification grid mesh 222 is provided on the air suction plate 225. The air suction plate 225 is arranged in the air suction port 224, the air suction plate 225 and the flip plate 223 form a triangular buffer space for oil smoke gas, when the air suction port 224 fails to timely and completely suck the oil smoke gas intercepted by the flip plate 223, the oil smoke gas can be temporarily accumulated in the triangular buffer space, and the oil smoke gas is prevented from floating upwards or towards a user. The arrangement of the rectification grid mesh 222 rectifies the oil fume intercepted by the flip plate 223, so that turbulence is reduced, and noise is reduced.

Example 2:

the difference from example 1 is that: as shown in fig. 5, an air suction plate 225 is fitted into the air suction port 224.

Example 3:

the difference from example 1 is that: as shown in fig. 6 and 7, the air suction plate 225 is obliquely disposed in the movable housing 211, a lower edge of the air suction port 224 is fixedly connected to one side surface of the air suction plate 225, an inner side wall of the movable housing 211 opposite to the air suction port 224 is fixedly connected to the other side surface of the air suction plate 225, and a cooking illumination lamp is fixedly disposed above the air suction plate 225 and irradiates towards the air suction port 224. A third air duct is formed between the air suction plate and the air suction port, and the third air duct is communicated with the second air duct 214. When the fan 12 works, a negative pressure area for absorbing oil smoke is formed at the third air channel, when oil smoke gas with strong impact and rising force is generated on the cooker, the flip plate 223 can not only prevent the oil smoke gas from rising upwards, but also the flip plate 223 can guide the oil smoke gas to enter the third air channel, and then the oil smoke gas is guided into the second air channel 214 through the rectifying grid mesh of the air absorbing plate, so that the absorbed rate of the oil smoke gas is improved.

The rotation driving member 221 is an electric push rod, and the electric push rod is obliquely arranged between the flip plate 223 and the movable housing 211 (the rotation driving member 221 may also be a motor).

The electronic switch loop of the electric push rod is provided with an overcurrent protection structure, when the flip plate 223 meets the object to block, the switch controller switches off the circuit of the electric push rod after the loop current becomes large, and the electric push rod stops working.

The turning cover plate 223 is a toughened glass plate, and the bottom surface of the turning cover plate 223 facing the top of the kitchen range is provided with an illuminating lamp 3. The toughened glass plate has intensity and convenient cleanness, and light 3 makes things convenient for the culinary art illumination.

The working principle is as follows: when the range hood needs to start working, the lifting driving piece 212 drives the movable shell 211 to rise from the table top, and when the movable shell 211 rises to a certain height, the movable shell stops rising. Then, the turning driving member 221 drives the turning cover plate 223 to turn, and the turning cover plate 223 is turned from a state of being attached to the movable housing 211 to a state of being perpendicular to the movable housing 211.

The inner space of the movable housing 211 is mostly occupied by the second air duct 214, the width of the second air duct 214 may be similar to the width of the air suction opening, and the suction force at each part of the air suction opening is uniform. When oil smoke gas with strong impact and rising force is generated on the cooker, the turning cover plate 223 prevents the oil smoke gas from rising upwards, the turning cover plate 223 changes the movement direction of the oil smoke gas from vertical to horizontal, and the turning cover plate 223 can also directly suck the oil smoke gas into the second air duct 214 from the second rectifying grid mesh. The air suction plate 225 is obliquely arranged in the air suction port 224, the air suction plate 225 and the turning plate 223 form a triangular buffer space, when the air suction port 224 fails to timely and completely supply and absorb the lampblack gas intercepted by the turning plate 223, the lampblack gas can be temporarily accumulated in the triangular buffer space, and the lampblack gas is prevented from flowing downwards or towards a user. The arrangement of the rectification grid mesh 222 rectifies the oil fume intercepted by the flip plate 223, so that turbulence is reduced, and noise is reduced.

When the range hood is not needed to work, the flip plate 223 is flipped downwards until being attached to the movable housing 211. In addition, in the process that the movable housing 211 slides downwards into the fixed housing 11, the flip plate 223 can slide into the fixed housing 11 along with the movable housing 211 to reset, and the range hood is attractive in appearance and small in occupied space.

While one embodiment of the present invention has been described in detail, the description is only a preferred embodiment of the present invention, and should not be considered as limiting the scope of the present invention. All the equivalent changes and improvements made according to the application scope of the present invention should still fall within the patent coverage of the present invention.
