Cross-reference to related applications This application claims priority to Chinese Patent Application No. 20192030363023.7 filed on March 21, 2019, the disclosure of which is incorporated herein by reference in its entirety.

The present invention relates to a device for heating a cigarette in a cigarette to allow a smoker to smoke the cigarette.

With the development of equipment for tobacco technology, the so-called "heating without smoking" smoking method, which involves heating the tobacco material without burning or smoking, has begun to be applied to ordinary cigarettes. For ordinary cigarettes, the amount of smoke produced by heating in the "heating without smoking" scheme is relatively small due to the filtering effect of the filters on the cigarettes. In order to improve the enjoyable experience made by smoking users, it is desirable to generate large amounts of smoke. Existing techniques for producing larger amounts of smoke are generally based on redirecting the smoke outlet so that it exits the end of the cigarette without passing through the filter. Smoke filter adsorption is reduced, thereby increasing the amount of smoke produced. However, this technique of smoking from a cigarette bat does not apply to normal smoking styles and is psychologically unacceptable to users. In addition, smoke from cigarette bats still contains some harmful substances such as tar. Thus, it is necessary to additionally install a filtering device for filtering smoke, which increases the cost. In addition, existing technologies generally consider producing only mainstream smoke, thus neglecting the use of sidestream smoke and thus reducing the efficiency of tobacco smoke utilization. Therefore, methods for increasing the amount of tobacco smoke and the efficiency of tobacco smoke utilization to satisfy the user's established smoking habits have become an urgent issue to be solved.

The present invention provides a device for heating a cigarette in a cigarette to allow a smoker to smoke. An object of the present invention is to improve the utilization efficiency of cigarette smoke. To this end, the present invention employs the following technical solutions.

As shown in FIGS. 1-3, a device 1000 for heating cigarettes according to an exemplary embodiment of the present invention is displayed. In particular, this device is used to heat cigarette cigarettes and allow users to smoke cigarettes. The device 1000 includes a housing 1, a heating tube 3 disposed inside the housing 1, and a base 2 connected to the housing 1. The battery power supply 02 can be mounted in the device 1000. The heating tube 3 is configured to be electrically connected to the battery power source 02 in order to heat the cigarette 100. As shown in FIG. 4, the heating tube 3 includes a first channel 31 for receiving the cigarette. The heating tube 3 is formed by an inner surface 380 for surrounding the first channel 31. Advantageously, the inner surface 380 has one or more recesses in itself. Each recess forms one second channel 32 adjacent to the first channel 31, thereby forming a set of one or more second channels 32. Therefore, the heating tube 3 further includes a set of one or more second channels 32. Here, a set of one or more second channels 32 is conveniently referred to as a second channel set 32. The second channel set 32 is arranged on the outer periphery of the first channel 31. Further, the first channel 31 and the respective second channels of the second channel set 32 communicate with each other. The base 2 is connected to the first channel 31 and the second channel set 32.

When the cigarette is placed in the first channel 31 for heating, the mainstream smoke produced by the cigarette 100 is emitted from the end of the cigarette. When inhaled by the user, the mainstream smoke passes through the cigarette and cigarette filter in the cigarette 100 and then through the mouthpiece 2 to reach the user's oral cavity. In addition to the mainstream smoke that passes through the cigarette filter, a portion of the smoke produced by the cigarette passes through the cigarette paper of the cigarette to form sidestream smoke. The sidestream smoke produced by the cigarette 100 is advantageously collected by the second channel set 32, transferred to the base 2, and inhaled by the user through the base 2 under the user's actions. By providing the first channel 31 and the second channel set 32, mainstream smoke and sidestream smoke are collected by the mouthpiece 2 and inhaled by the user, whereby the user smokes directly in the cigarette filter, in this case. Prevents only mainstream smoke from being consumed and sidestream smoke from being wasted. In addition, the mainstream smoke volume is large, so that some harmful substances in the mainstream smoke are filtered by the cigarette filter. However, the amount of sidestream smoke is small. Sidestream smoke may also be safely absorbed by the user by simple filtering with cigarette paper.

Specifically, referring to FIG. 4, the device for heating the cigarette includes at least one second channel 32 arranged circumferentially along the first channel 31, and each of them. The long axis of the second channel 32 is parallel to the long axis of the first channel 31. Preferably, the device 1000 for heating the cigarette is provided with three second channels 32 and between the two second channels 32 adjacent to the long axis of the first channel 31. The extending angle is 120 degrees. Optionally, each second channel 32 may have a cross section greater than 0.1 mm ² . The cross section of each second channel 32 may be determined by one of ordinary skill in the art according to actual conditions. In existing or previous "heating without smoking" smoking methods for heating ordinary cigarettes, smoke aerosols exit from the ends of the cigarette away from the cigarette filter, resulting in smoke aerosol filtering. As a result, harmful substances such as tar may be directly inhaled by the user. However, in the present invention, the smoke has three passages, which are the cigarette filter, the bottom end of the cigarette and the sides of the cigarette. By providing the second channel set 32 around the cigarette 100, there is a space between the cigarette 100 and the heating tube 3, so that the smoke aerosol passes through the cigarette paper into the second channel set 32. You may proceed. The cigarette paper may act as a sieving paper, and dangerous substances such as tar may be blocked by the cigarette paper, thus leaving a cleaner smoke aerosol for the user.

The heating tube 3 may be a metal heating tube, a ceramic heating tube, or a carbon material heating tube. Optionally, the heating tube 3 may be an alumina ceramic heating tube. In this case, the inner surface of the alumina ceramic heating tube comprises a resistance material, which may generate heat when energy is applied to heat the cigarette 100 in contact with it. The resistance of the resistant material may be between 0.05 and 5 Ω.

Further, by disposing the heat insulating layer 4 on the outside of the heating tube 3, the hot air generated during heating the cigarette is isolated, and the electronic components inside the housing 1 are protected. The heat insulating layer 4 also prevents an unpleasant experience for the user, such as burns, by preventing excessive heat transfer to the housing 1. Moreover, by having the heat insulating layer 4, the heat generated by the heating tube 3 is sufficiently concentrated in the vicinity of the heating tube 3 instead of being transferred far away, thereby improving the heating efficiency. The insulation layer 4 may include a foam structure formed from Teflon®, polyetheretherketone (PEEK) or another organic polymer material, as well as aluminum silicate ceramic fibers, silica airgel and porous ceramic tubes. It may contain an inorganic material such as. Alternatively, the insulating layer 4 may be made of silica airgel. Further, the heat insulating layer 4 may have a thickness of about 1 to 5 mm. Regardless of that, the thickness of the insulating layer 4 may be set by one of ordinary skill in the art according to certain conditions. The above minimum and maximum ranges are not limited to the present invention. In addition, a fixed layer may be further disposed on the outside of the heat insulating layer 4, and a polymer membrane may be used as the fixed layer. The polymer film may be a polyimide (PI) tape.

As shown in FIG. 2, the smoke storage chamber 01 may be arranged in the device 1000 for heating the cigarette, optionally. In general, the chamber 01 may be located near or away from the mouthpiece, preferably the smoke storage chamber 01 is located away from one end of the mouthpiece. The user has a poor ingestion experience at this time by placing the cigarette 100 in the heating tube 3 and producing less smoke when the cigarette 100 is first heated. By arranging the smoke storage chamber 01, no suction is performed when the cigarette 100 is first heated. As a result, the smoke produced by the cigarette 100 is initially collected in the storage chamber 01, and after a certain period of smoke collection, the user enjoys a better smoking experience with a relatively large amount of smoke. You may. If the storage chamber 01 is not provided, the smoke in the cigarette 100 is emitted throughout the interior of the housing 1 and cannot be well consumed by the user. Unsurprisingly, after the cigarette 100 has been heated, the smoke is primarily emitted from the end of the cigarette away from the cigarette filter. Therefore, in one embodiment, the storage chamber 01 is arranged at one end of the heating tube 3 away from the mouthpiece 2. It may also be installed in a different location in another embodiment. Specifically, the cigarette 100 is placed in the heating tube 3 and there is a support portion for supporting the cigarette 100. In one embodiment, the diameter of the support portion is smaller than the diameter of the heating tube 3, and the space between the outer wall of the support portion and the inner wall of the heating tube 3 may be used to form the storage chamber 01. .. Optionally, the support portion may include a third channel and one end of the heating tube 3 away from the mouthpiece 2 may include a smoke storage chamber 01. The third channel is used to connect with the heating tube 3 and the storage chamber 01.

See FIG. Optionally, the apparatus 1000 for heating the cigarette may further be provided with a structure for axially compressing the cigarette 100. By compressing the cigarette 100 in the axial direction, the surface of the cigarette paper is wrinkled. First, it should be noted that the diameter of the first channel 31 is larger than the outer diameter of the cigarette 100 to accommodate the cigarette 100. Second, the inner surface 380 surrounding the first channel 31 does not flatten the cigarette paper pleats, leaving their wrinkles there, thereby increasing the flow space for sidestream smoke. As a result, the fluidity of sidestream smoke is improved. In particular, the base 2 limits the height of the cigarette 100 when the cigarette 100 is inserted into the first channel 31 by disposing a height limiter 8 at one end of the first channel 31. The cigarette 100 is compressed by the above. A support portion for supporting the cigarette 100 is provided at the end of the first channel 31 away from the base 2. The distance between the support portion adjacent to the end of the base 2 and the height limiter 8 is less than the length of the cigarette 100. The cigarette 100 is placed between the height limit 8 and the support portion. When the cigarette 100 is inserted into the first channel 31, the cigarette 100 will be axially compressed by the height limit 8 and the support portion, and therefore wrinkles will be generated on the outer surface of the cigarette 100. To. Optionally, the height limit 8 inside the base 2 is detachably connected to the base 2 in order to replace the height limit 8 with a suitable one that fits cigarettes of different heights and thicknesses. You may. As an alternative, the first channel 31 may be provided with a support portion that supports the cigarette 100 at a position away from the end of the base 2. The support portion comprises a pressing rod assembly in which the pressing rod 61 of the pressing rod assembly abuts on one end of the cigarette 100. The distance between the end of the pressing rod 61 facing the base 2 and the height limiter 8 may be less than or equal to the length of the cigarette 100, depending on the choice. After the cigarette 100 is placed in the first channel 31, the mouthpiece 2 (without the height limit 8) is installed, then the pressing rod 61 is moved towards the mouthpiece 2, thereby causing the cigarette 100 to axis. It is compressed in the direction and wrinkles are generated on the outer surface of the cigarette 100. In addition, when the cigarette 100 is axially compressed by the pressing rod 61, the space of the smoke storage chamber 01 disposed at one end of the heating tube 3 away from the mouthpiece 2 is further increased, which Collects more cigarette smoke and therefore provides the user with stronger smoke with a better experience. Of course, optionally, the device 1000 for heating the cigarette is also provided with a height limiter 8 in the mouthpiece 2 with a support portion for supporting the cigarette 100 provided as a pressing rod assembly. You may be.

Further, the pressing rod assembly includes a connecting pedestal 62. The inner wall of the connection pedestal 62 may be hermetically connected to the side wall of the pressing rod 61. One end of the pressing rod 61 facing the mouthpiece 2 extends into the heating tube 3 to prevent cigarette smoke from escaping out of the housing 1. Optionally, the limiting groove may be disposed on the connecting pedestal 62 away from the side surface of the heating tube 3. Correspondingly, the limiting portion is arranged on the outer periphery of the pressing rod 61 to prevent the pressing rod 61 from excessively protruding into the heating tube 3. Otherwise, excessive compression of the cigarette 100 will result, which does not contribute to the circulation of mainstream smoke. Further, the pressing rod 61 is provided with a pressing handle 611 at one end away from the cigarette 100, and the pressing handle 611 allows the user to press the pressing rod 61 toward the cigarette 100, or presses the pressing rod 61.
