Description

Disposable suction nozzle and kit

Technical Field

The utility model belongs to the technical field of eating, and particularly relates to a disposable suction nozzle and a kit.

Background

This section provides merely background information related to the present disclosure and is not necessarily prior art.

The bursting beads, also called as fragrant pills, brittle capsules or beads, wrap the liquid of different types of spices and can be embedded in the tobacco filter tip, and a smoker can burst the bursting beads in the smoking process to force the liquid in the bursting beads to flow out and infiltrate the tobacco filter tip, so that the taste of the cigarette is richer, more fragrant and moist, and more comfortable experience is provided for the smoker. Some cigarettes are pre-impregnated with the bead during manufacture, whereas for ordinary cigarettes that are not pre-impregnated with the bead, it is necessary for the smoker to implant the bead into the tobacco filter of the cigarette by himself.

Generally, a smoker firstly opens a hole for accommodating the explosion bead at the end or the outer side wall of the tobacco filter by a tool such as a knife, a needle and the like, then plugs the explosion bead into the opened hole, and further reforms the common cigarette without pre-embedding the explosion bead into the cigarette with the explosion bead. The existing bead explosion installation mode is troublesome to operate, various cigarette filter tip sizes are faced, the size of the holes are not easy to control, the cigarette filter tip is extremely easy to damage, the smoke filtering effect of the filter tip is poor or the smoke cannot be filtered completely, and the cigarette cannot be used or the health of a smoker is affected due to poor filtering efficiency.

In addition, after the explosion beads are embedded, the explosion beads are required to be manually extruded to be broken, the probability that the explosion beads cannot be broken or the effect of improving the taste due to the fact that the explosion beads are too close to the filter tip is poor, and the user experience is poor.
