Of course, other shapes of heating elements that are easily rotated may be used. The arrangement of the whole airflow channel of the low-temperature smoking set is not the improvement point of the invention, and the existing arrangement form can be adopted, and the detailed description is omitted.

As shown in fig. 4-6, when the low temperature cigarette of this embodiment is used, the cigarette 5 is inserted into the receiving cavity 1 of the smoking set, and at the same time, the heating element 2 pierces into the cigarette 5, the heating element 2 heats the cigarette 5 to generate smoke, the heating element 2 is located inside the smoking set, after a cigarette is drawn, the rotation driving mechanism 3 drives the heating element 2 to rotate relative to the cigarette 5, the cigarette 5 is in a static state because of failing to overcome the static friction force with the receiving cavity 1, so that the heating element 2 is separated from the tobacco shred in the cigarette 5, and the tobacco shred adhered to the heating element 2 is separated from the heating element 2 under the centrifugal force, and the tobacco shred separated from the heating element 2 is adhered to the other tobacco shreds in the cigarette 5 again because of a certain adhesive force, so as not to be deposited at the bottom of the receiving cavity 1. In addition, before a cigarette 5 is pulled out, the linear driving mechanism 4 drives the heating body 2 to make a separating motion relative to the cigarette 5, which is equivalent to giving an axial separating force to the adhered tobacco shreds, further separating from the heating body 2, and when the cigarette 5 is pulled out from the low-temperature smoking set, the smoking material can be more effectively prevented from falling off in the smoking set.

It should be noted that, in the process of withdrawing the heating element 2, the side wall of the through hole for inserting the heating element on the cigarette sleeve 17 can also scrape the residual tobacco shred on the heating element 2, and further clean the heating element 2, and the residues such as the tobacco shred or tobacco tar falling from the cigarette are all contained in the cigarette sleeve 17, so that other parts of the smoking set cannot be polluted, and only the cigarette sleeve 17 needs to be cleaned or replaced, and the whole smoking set does not need to be replaced.

In this embodiment, lower casing 601 and upper cover 602 can adopt modes such as buckle connection, screw fit or magnetic adsorption to connect, if when adopting the magnetic adsorption mode, through set up magnet respectively at upper cover 602 and lower casing 601 butt joint end, the upper cover 602 lid is closed when casing 601 is gone up down and is realized fixing through the interact between the magnet, and this kind of connected mode has separation and simple to operate's characteristics.

In practical design, in order to facilitate the installation of the cigarette holder 17, a guide support 18 suitable for the insertion of the cigarette holder 17 may be further fixedly installed in the lower housing 602, the cigarette holder 17 is guided by the guide support 18, the heating element fixing seat 15 is slidably installed in one end of the guide support 18 away from the insertion end of the cigarette holder 17 in a matching manner and can rotate relative to the guide support 18, and a return spring 19 is arranged between the guide support 18 and the heating element fixing seat 15, that is, a compression space of the return spring 19 is used as a stroke of the heating element fixing seat 15. When the cigarette sleeve 17 is inserted into the guide bracket 18, the heating body 2 is over against the through hole on the closed end of the cigarette sleeve. Specifically, the heating element fixing base 15 has a constricted portion in its circumferential direction, which extends out of the guide holder 18, and the constricted portion has a center hole that matches the rotary shaft 7 of the drive motor. When the heating element fixing seat is installed, the rotating shaft 7 of the driving motor is clamped in the central hole in an interference fit mode, and when the driving motor works, the rotating shaft 7 can drive the heating element fixing seat 15 and the heating element 2 to synchronously move.

The above examples are merely illustrative for clearly illustrating the present invention and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. Nor is it intended to be exhaustive of all embodiments. And obvious variations or modifications of the invention may be made without departing from the scope of the invention.
