Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the accompanying drawings are exemplary only for explaining the present invention, and should not be construed as limiting the present invention.

A range hood 1 according to an embodiment of the present invention is described below with reference to the drawings.

As shown in fig. 1-7, a range hood 1 according to an embodiment of the present invention includes a range hood main body 100 and a smoke blocking assembly 700.

The cigarette machine main body 100 defines a lower smoke suction cavity 122 with a front opening, the front opening forms a lower smoke suction port 121, and the smoke can enter the cigarette machine main body 100 from the lower smoke suction port 121 and then is discharged by the range hood 1.

The smoke blocking assembly 700 is arranged on the cigarette machine main body 100, the smoke blocking assembly 700 comprises a smoke blocking piece 710 and a driving device 720, and the driving device 720 is connected with the smoke blocking piece 710 and used for driving the smoke blocking piece 710 to move, so that the smoke blocking piece 710 can move along the front-back direction to open or close the lower smoke suction port 121, and the use requirements of users are met.

For example, when a user needs to open the lower smoke inlet 121 and smoke through the lower smoke inlet 121, the driving device 720 can drive the smoke blocking member 710 to move backward, and at this time, the smoke blocking member 710 opens the lower smoke inlet 121, so that the smoke can enter the lower smoke inlet 121.

When the user need not open lower smoking mouth 121, drive arrangement 720 can drive and keep off cigarette piece 710 and move forward, keeps off cigarette piece 710 and closes lower smoking mouth 121 this moment, avoids pollutants such as dust to get into lower smoking chamber 122 from lower smoking mouth 121, causes the pollution to lower smoking chamber 122, can protect to a certain extent spare part in the lower smoking chamber 122 and the environment in the lower smoking chamber 122.

As shown in fig. 5, when the smoke blocking member 710 closes the lower smoke port 121, the dirt in the lower smoke chamber 122 can be prevented from being exposed to the outside, and the smoke blocking member 710 can be flush with the wall surface of the cigarette machine body 100 forming the lower smoke port 121, so that the aesthetic property of the whole cigarette machine body 100 can be improved while the lower smoke port 121 is closed.

Therefore, according to the utility model discloses lampblack absorber 1 has can open or close smoking mouth, improve advantages such as aesthetic property of lampblack absorber 1 according to the demand.

A range hood 1 according to a specific embodiment of the present invention is described below with reference to the accompanying drawings.

As shown in fig. 1-7, a range hood 1 according to an embodiment of the present invention includes a range hood main body 100 and a smoke blocking assembly 700.

In some embodiments of the present invention, the driving device 720 includes a plurality of driving devices 720, and the plurality of driving devices 720 are arranged along the length direction of the smoke blocking member 710, so as to stably drive the smoke blocking member 710 to move along the front and back direction, so that the smoke blocking member 710 can stably open or close the lower smoke absorbing opening 121.

In some embodiments, as shown in fig. 2, the length direction of the smoke barrier 710 extends along the left-right direction, the plurality of driving devices 720 are arranged at intervals along the left-right direction, and the plurality of driving devices 720 can synchronously drive the smoke barrier 710 to stably move along the front-back direction, so that the smoke barrier 710 can stably open or close the lower smoke outlet 121.

In some embodiments of the utility model, the driving device 720 includes mobilizable connecting rod 721 and motor, and connecting rod 721 extends along the fore-and-aft direction, and the one end of connecting rod 721 is connected with cigarette piece 710, and the motor cooperates with connecting rod 721 for drive connecting rod 721 activity can drive cigarette piece 710 and remove along the fore-and-aft direction at the in-process that connecting rod 721 moved about, and cigarette mouth 121 under opening or closing is kept off in order to drive cigarette piece 710.

In some embodiments, as shown in fig. 5 and 6, the front end of the connecting rod 721 is connected to the rear portion of the smoke barrier 710, and the motor can drive the connecting rod 721 to move in the front-back direction, so that the connecting rod 721 drives the smoke barrier 710 to move in the front-back direction, thereby further opening or closing the lower smoke barrier 121 by the smoke barrier 710. In some optional embodiments of the utility model, drive arrangement 720 still includes the driving medium, and the driving medium cooperates with motor, connecting rod 721 for turn into the moving motion of connecting rod 721 with the rotary motion of the motor shaft of motor, move along the fore-and-aft direction with the moving motion drive through connecting rod 721 that keeps off cigarette piece 710, make cigarette piece 710 open or close down smoking mouth 121.

In some embodiments, the transmission member is a lead screw disposed between the motor and the connecting rod 721 to convert the rotational motion of the motor into a translational motion and transmit the translational motion to the connecting rod 721 to realize the translational motion of the connecting rod 721, so that the connecting rod 721 can move in the front-back direction.
