As shown in fig. 1, the smoke collecting plate 2 is located at a storage position, and in the storage position, the smoke collecting plate 2 can be attached to the main body 1 of the cigarette machine. Because in this embodiment, the tobacco gathering plate 2 is a movable tobacco gathering plate 2, and can be rotatably connected and/or detachably connected with the main body 1 of the range hood, in the storage position, the tobacco gathering plate 2 can be folded and attached to the main body 1 of the range hood, thereby saving occupied space, and being very suitable for the use situation of the portable range hood.

In this embodiment, the connection of the smoke collecting plate 2 is also optimized, specifically: the smoke collecting plate 2 is rotationally connected above the air inlet 101, the working positions comprise a maximum working position and a minimum working position, the maximum working position and the minimum working position are set, the working area or the working range of the smoke collecting plate 2 can be wider, so that the smoke collecting plate is suitable for more use scenes, meanwhile, a rotational damping force exists when the smoke collecting plate 2 rotates between the maximum working position and the minimum working position, and the rotational damping force can enable the smoke collecting plate 2 to hover at any position between the maximum working position and the minimum working position, so that the possibility that the smoke collecting plate 2 is easily pushed by rising smoke and air flow is reduced, and the possibility that the smoke collecting plate 2 freely descends due to dead weight is also reduced.

As shown in fig. 4, the position where the dotted line is located in this embodiment is the minimum working position, and the horizontal position of the smoke collecting plate 2 is the maximum working position, and in the process of rotating the smoke collecting plate 2 between the minimum working position and the maximum working position, a damping force exists between the smoke collecting plate 2 and the main body 1 of the cigarette machine.

For the rotation damping force between the smoke gathering plate 2 and the smoke machine main body 1, the mode of realizing the embodiment is that the smoke gathering plate 2 is connected with the smoke machine main body 1 through the rotating shaft 3, and the rotating shaft 3 is provided with a damper which can provide damping force between the rotating shaft 3 and the smoke gathering plate 2 or between the rotating shaft 3 and the smoke machine main body 1.

In order to enable the smoke collecting plate 2 to be more convenient to store, the setting of the rotation damping force is also optimized in the embodiment, and the rotation damping force is not set when the smoke collecting plate 2 rotates between the minimum working position and the storing position or is smaller than the rotation damping force between the maximum working position and the minimum working position. The purpose of this design is to allow the smoke collecting plate 2 to rotate more smoothly from the minimum operating position to the storage position during storage, and to allow the smoke collecting plate 2 to enter the operating position more quickly during expansion. In this embodiment, it is preferable that no rotational damping force is provided when rotating between the minimum operating position and the storage position. After such design, when the user rotates the smoke collecting plate 2 to the minimum position, the smoke collecting plate 2 can also recover to the collecting position by means of self weight.

For the preferred position of the minimum working position, in this embodiment, the smoke collecting plate 2 is in a vertical state when in the storage position, and is in a horizontal state when in the maximum working position, if the rotation angle between the minimum working position and the storage position is a, the rotation angle a is preferably 15 degrees or more, less than 90 degrees, 30 °, 45 °, 60 ° and the like can be generally selected, and generally, if the rotation angle a is less than 15, the expansion angle of the smoke collecting plate 2 is too small, the smoke collecting effect is poor, and if the rotation angle a is greater than 90 degrees, the rising smoke will continue to run upwards, which is also unfavorable for collecting smoke.

For the structure of the damper: the damper is an angle-adjustable damper, the angle-adjustable damper is arranged at two ends of the rotating shaft 3, the smoke machine main body 1 is provided with a shaft hole for installing the rotating shaft 3, and the angle-adjustable damper is arranged in the shaft hole. The angularly adjustable damper can achieve a damping force in a specific angular range, and as for the angularly adjustable damper, since a great deal of disclosure is already made, it will not be described herein.

Of course, in other embodiments, the structure of the damper is not limited to the angle-adjustable damper, but may be other structures, and see example two below.

As described above, in this embodiment, the connection relationship between the smoke collecting plate 2 and the main body 1 of the cigarette machine is both rotationally connected and detachably connected, and the specific implementation manner is as follows: the cigarette machine main body 1 is rotatably connected with the rotating shaft 3 above the air inlet 101, the rotating shaft 3 is rotatably connected with the cigarette machine main body 1, and the cigarette gathering plate 2 is arranged on the rotating shaft 3, so that the cigarette gathering plate 2 is rotatably connected with the cigarette machine main body 1, and meanwhile, the rotating shaft 3 is detachably connected with the cigarette gathering plate 2, and as for the detachable structure, the rotating shaft 3 and the cigarette gathering plate 2 can be in interference fit connection, or buckle connection or magnetic attraction connection, and in the embodiment, the rotating shaft 3 and the cigarette gathering plate 2 are in magnetic attraction connection for convenient disassembly and cleaning.
