Description

The present invention relates to the field of tobacco substitutes, and more particularly to low temperature baking smoking articles.

Existing non-heated, non-combustible, low temperature baking smoking devices often utilize a heating element to heat tobacco substrates such as cigarettes and atomize the tobacco substrates to generate an aerosol for inhalation by the user. After puffing, the user pulls the cigarette out of the heating element to achieve separation of the heating element and the cigarette. Tobacco, when heated, forms a certain sticky substance that adheres to the heating element to form a sticky state, and more sticky substance remains on the surface of the heating element. When a single cigarette has been heated, the pipe containing the tobacco is usually first removed from the low-bake smoking article, then the tobacco is removed from the pipe, and the pipe is attached to the low-bake smoking device for subsequent use.

As shown in FIG. 2, the cigarette 7 is inserted into the slide smoke pipe 3 through the cigarette insertion opening 111 . At this time, when the cigarette 7 is pushed, the slide block 331 of the slide smoke tube 3 slides in the corresponding first slide groove 421 and/or the second slide groove 422 under the thrust action of the cigarette 7, and the slide sleeve 5 is moved. Slide down along the first slide groove 421 . When the guide block 51 slides downward until it is out of the first slide groove 421, if the cigarette 7 is kept pressed, the zigzag projection 332 engages with the first meshing surface 511, thereby rotating the slide sleeve 5 in a certain direction. , presses the elastic part 6 to slide it downward. When the pressure on the cigarette 7 is released, the sliding sleeve 5 moves back up under the action of the elastic element 6, so that the first engaging surface 511 abuts the first inclined surface 411, the side wall 512 abuts the longitudinal side 413, This locks the guide block 51 and elastically holds the slide smoke tube 3 in the operating position. At this time, the slide smoke pipe 3 slides downward with respect to the cigarette insertion opening 111 by a certain distance, whereby the insertion part 211 is completely extended into the insertion hole 36 . At this time, the tobacco 7 inserted into the slide smoke tube 3 can be baked by the heating element 21 .

After heating the cigarette 7, the cigarette 7 is pressed again to push the slide smoke tube 3 and the slide sleeve 5 downward. As a result, the first engaging surface 511 is separated from the first inclined surface 411, and the zigzag protrusion 332 engages with the first engaging surface 511, thereby rotating the slide sleeve 5 in a certain direction. When the pressure on the cigarette 7 is released, the slide sleeve 5 moves back up under the action of the elastic element 6, so that the guide block 51 slides into the adjacent first slide groove 421. FIG. Under the action of the elastic element 6 it continues to slide back up until the slide smoke tube 3 again returns to the separated position shown in FIG. At this time, the slide smoke tube 3 is slid upward with respect to the heating element 21 by a certain distance, whereby at least a part of the insertion part 211 is removed from the insertion hole 36, and the separation of the cigarette 7 and the heating element 21 is realized, and the cigarette is It is convenient to remove 7. It reduces or prevents any residual material from the cigarette 7 from sticking to the heating element 21 .
