Detailed Description

The present invention will now be described more fully hereinafter with reference to the accompanying examples.

Referring to the attached figure 1, a rotary shaft feeding type smoke generating device comprises a smoke generating furnace 1 and a feeding mechanism.

The smoke generating furnace 1 is of a rectangular tubular structure, the upper end of the smoke generating furnace 1 is communicated with a smoke guide pipe 2, and the middle part of the smoke generating furnace 1 is fixedly provided with a combustion net 3. The side wall of the smoke generating furnace 1 is also provided with a material taking port 4 and an air inlet 5, wherein the material taking port 4 is positioned above the combustion net 3, and the air inlet 5 is positioned below the combustion net 3.

With reference to the attached drawing 2, the feeding mechanism comprises a feeding bin 6 which is fixed on the smoke generating furnace 1 and is communicated with the smoke generating furnace 1, the feeding bin 6 is positioned on one side, away from the smoke guide pipe 2, of the smoke generating furnace 1, and a valve plate 7 is hinged to the communicating position of the feeding bin 6 and the smoke generating furnace 1. Under the general condition, the valve plate 7 naturally droops under the action of gravity, and the joint of the feeding bin 6 and the smoke generating furnace 1 is sealed, so that smoke is prevented from entering the feeding bin 6. When the tobacco cake falls, the tobacco cake can fall into the fuming furnace 1 under the action of gravity. One side of the feeding bin 6 is provided with an opening and is hinged with a feeding door 18.

Throw the articulated three baffle 8 that is provided with in the feed bin 6, throw feed bin 6 and keep away from one side rotation of leading tobacco pipe 2 and be provided with vertical pivot 9, combine figure 3, fixedly on the pivot 9 be provided with three control flap 10 that are used for supporting baffle 8, control flap 10 is jagged circular structure and mutual dislocation set. The partition 8 is kept horizontal under the support of the control plate 10, and when the rotating shaft 9 is rotated to make the notch on the control plate 10 reach the corresponding partition 8, the side of the partition 8 close to the rotating shaft 9 loses the support and falls off.

With reference to fig. 4, the control plate 10 at the lowest side is provided with a plurality of clamping holes 11, and the feeding bin 6 is provided with a ball spring 12 which is embedded and matched with the clamping holes 11. After the rotating shaft 9 rotates by a fixed angle, the ball spring 12 will be snapped into the next snap hole 11 again, thereby providing feedback to the tester rotating the rotating shaft 9.

The pivot 9 is provided with the horizontally dwang, and the dwang includes threaded sleeve 13 and the body of rod 14, threaded sleeve 13 and the 14 threaded connection of the body of rod, threaded sleeve 13 and pivot 9 fixed connection. And a heat insulation handle 15 is fixedly arranged at one end of the rod body 14, which is far away from the threaded sleeve 13, so that a tester can conveniently grasp the heat insulation handle. The smoke generating furnace 1 is fixedly provided with an elastic clamping ring 16, and the rod body 14 can be fixed on the outer side wall of the smoke generating furnace 1 by utilizing the elastic clamping ring 16 after the rod body 14 is detached. The feeding bin 6 is also marked with a direction mark 17 for assisting the rotating shaft 9 to rotate.

The working principle of the embodiment is as follows: in use, a measured amount of the cake is first placed on the combustion mat 3 and each partition 8, and then the hot smoke test is initiated by igniting the cake on the combustion mat 3. When the tobacco cake on the burning net piece 3 is about to burn out, the dwang is stirred to the experimenter level, and the dwang drives pivot 9 and rotates to the breach department that makes downside control piece 10 reachs and corresponds 8 departments of baffle, this baffle 8 no longer receives the support of control piece 10 and drops, and the tobacco cake on this baffle 8 will also fall burning net piece 3 on, is lighted by the tobacco cake that is burning. And circulating the steps until the hot smoke test is completed. This kind of mode can drop into the smoke generating furnace 1 with the cigarette cake convenient and fast ground, does not need the experimenter to throw the material by the manual work one by one, has greatly made things convenient for experimenter's operation, guarantee experimenter's safety.

The above, only be the utility model discloses the embodiment of preferred does not restrict according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
