Device for Heating Tobacco

Abstract

In a device for heating tobacco in a cigarette, a heating tube heats the cigarette to generate smoke. The heating tube has a first channel and a set of one or more second channels. Each second channel is disposed at an outer circumference of the first channel and is in connection with the first channel. The first channel receives the cigarette and conducts mainstream smoke, which is a portion of the smoke passing through the tobacco and a cigarette filter in the cigarette. The second channel set collects and conducts side-stream smoke, which is a portion of the smoke passing through a cigarette paper of the cigarette. The mouthpiece is connected to both the first channel and the second channel set to provide not only the mainstream smoke but also the side-stream smoke for a smoker to inhale, thereby avoiding wasting the side-stream smoke.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims priority to Chinese Patent Application No. 201920363023.7, filed on Mar. 21, 2019, the disclosure of which is incorporated by reference herein in its entirety.FIELD OF THE INVENTION[0002]The present invention relates to a device for heating tobacco in a cigarette for enabling a smoker to smoke the cigarette.BACKGROUND[0003]With the development of device for tobacco technology, a so-called “heating-without-smoldering” smoking method by heating the tobacco material without burning or smoldering is started to be applied to ordinary cigarettes. For the ordinary cigarettes, the amount of smoke generated by heating in a manner of “heating-without-smoldering” is relatively small due to the filtering effect of the filter on the cigarette. To enhance enjoyable experience made by a user during smoking, generating a large amount of smoke is desirable. Existing techniques for producing a larger amount of smoke are generally bas...

AI Technical Summary

Benefits of technology

The present invention is about a device that heats tobacco in a cigarette to make it easier for a smoker to inhale the smoke. The device has a heating tube with two channels: one for the mainstream smoke and another for the side-stream smoke. The device also has a mouthpiece that connects to both channels, allowing the smoker to inhale both types of smoke. The mouthpiece has a support portion that compresses the cigarette to enhance the flowability of the side-stream smoke. This results in a more efficient use of tobacco smoke.

Problems solved by technology

However, this approach of smoking from cigarette butts does not conform to the normal smoking style, and the user is psychologically unacceptable.

In addition, the smoke from the cigarette butt still contains some harmful substances such as tar.

As such, it is necessary to additionally install a filtering device to filter the smoke and the cost is therefore increased.

In addition, the existing techniques generally consider the export of mainstream smoke only, and neglect the utilization of side-stream smoke, thereby reducing the utilization efficiency of tobacco smoke.

Therefore, how to increase the amount of tobacco smoke and the efficiency of utilizing the tobacco smoke in order to meet the user's established smoking habit has become an urgent problem to be solved.
