Description

Technical Field

[0001] The invention belongs to the field of novel cigarette smoking articles, and in particular relates to a closed heating smoking article with a cigarette locking device and a cigarette assembly. Background Art

[0002] At present, when heating, the smoke-generating substrate of most heat-not-burn cigarettes can directly contact the outside air through the airway. This means that on the one hand, the heating temperature cannot be too high to avoid burning the heating substrate, but if the temperature is not high enough, the aroma of the cigarette will not be fully released; on the other hand, the smoke generated by heating will reflux and condense in the airflow channel, and there will be residual smoke residue when the cigarette is extracted, which is easy to pollute the smoking utensils and difficult to clean. In addition, in order to ensure the smooth insertion of the cigarette, the inner diameter of the cigarette holding cavity must be larger than the outer diameter of the cigarette, and there is a gap between the two, which makes it easy for the cigarette to move or fall.

[0003] The present invention is proposed to solve the above-mentioned problems. Summary of the invention

[0004] The present invention is proposed to solve the above-mentioned problems.

[0005] A first aspect of the present invention provides a closed heating smoking device with a cigarette locking device, the smoking device comprising:

[0013] The second aspect of the present invention provides a closed heating cigarette assembly with a cigarette locking device, which comprises the smoking device and a closed cigarette 101 as described in the first aspect;

[0014] The inner diameter of the sealing sleeve 402 of the smoking device in a loosened state is larger than the outer diameter of the cigarette;

[0015] The inner diameter of the sealing sleeve 402 in the locked state is equal to or smaller than the outer diameter of the cigarette, or the inner diameter of the sealing sleeve 402 in the locked state is equal to or smaller than the outer diameter of the cigarette after thermal expansion;

[0016] The inner diameter of the cigarette accommodating cavity 103-2 is greater than the outer diameter of the cigarette;

[0017] The cigarette 101 comprises a tobacco section 113, a cooling section 112 and a filtering section 111 which are sequentially connected from upstream to downstream, wherein the cooling section 112 is a tube having an axial central cavity 112-1 and at least one circumferential side wall through hole 112-2.

[0018] Preferably, the sealed cigarette 101 is wrapped with an external wrapping member 114; a coaxial through hole 114-1 is provided on the external wrapping member 114 at a position corresponding to the side wall through hole 112-2, and the aperture of the coaxial through hole 114-1 is not less than the aperture of the side wall through hole 112-2.

[0019] Preferably, the depth of the cigarette accommodating cavity 103 - 2 is smaller than the distance between the at least one circumferential side wall through hole 112 - 2 on the cigarette and the upstream end of the tobacco segment 113 .

[0020] Preferably, the heating element 103 - 1 is a central heating element or a circumferential heating element, and its length is not greater than the length of the tobacco segment 113 .

[0021] The heating element 103 - 1 directly or indirectly contacts the tobacco segment 113 to provide heat to the tobacco segment 113 to make it smoke.

[0022] Preferably, when the cigarette 101 is inserted into the smoking device, the contact portion of the sealing sleeve 402 and the cigarette 101 is the upper end of the tobacco segment 113 or the lower end of the cooling segment 112, and the sealing sleeve 402 does not cover the side wall through hole 112-2 on the cooling segment 112; when the sealing sleeve 402 is locked with the cigarette 101, the cigarette accommodating cavity 103-2 is sealed, and outside air can only enter the cigarette 101 from the side wall through hole 112-2.

[0023] Preferably, the upstream end of the tobacco segment 113 is sealed in such a manner that: the circumference and / or the upstream end face of the tobacco segment 113 is wrapped with an airtight or controllable air permeability paper-based or foil-based material to form a closed system; or the upstream end of the tobacco segment 113 is coaxially abutted with a plug.

[0024] Preferably, the smoking device further comprises a cigarette insertion opening, which is arranged at the upper end of the cigarette accommodating cavity. The sealing sleeve 402 is arranged inside the cigarette insertion opening.

[0025] Preferably, the side wall through hole 112 - 2 may be in a circular, triangular, square or other polygonal shape.

[0026] The power supply 107 provides energy to the control panel assembly 106 , the sealing assembly 104 and the heating assembly 103 . The switch assembly 105 controls the start and stop of the heating process. The control panel assembly 106 controls the temperature output by the heating assembly 103 and the state of the sealing assembly 104 .

[0027] The method of using the above-mentioned enclosed heating cigarette assembly with a cigarette locking device is as follows:

[0028] When smoking a cigarette, first confirm that the sealing sleeve 402 is in a loose state, insert the cigarette 101 into the cigarette accommodating chamber 103-2, operate the switch assembly 105 to start heating, and the control board assembly 106 sends a positive signal to the driving device 401 to make the sealing sleeve 402 lock the cigarette 101, and then the control board assembly 106 controls the heating element 103-1 to start heating the cigarette 11.

[0029] During the heating process, smoke will be generated inside the tobacco segment 113 to replace the original air. At this time, the ignition point of the tobacco will increase, and combustion will not occur even if the temperature of the heating component 103 is high.

[0030] During inhalation, external cold air enters the cigarette 101 from the side wall through hole 112-2 on the cooling section 112, and enters the user's oral cavity through the filtering section 111. The high-speed flowing external air generates negative pressure in the cavity of the cooling section 112, triggering the Venturi effect and the Coanda effect, which has the function of extracting the smoke in the tobacco section 113. The cold air and the high-temperature smoke are neutralized in the cooling section 112 and the filtering section 111 to form a suitable inhalable gas.

[0031] After the inhalation is finished, the control panel assembly 106 sends a reverse signal to the driving device 401 to make the sealing sleeve 402 release the cigarette, and the control panel assembly 106 controls the heating assembly 103 to stop heating the cigarette 101 .

[0032] The above technical solutions can be freely combined under the premise of no contradiction.

[0033] The present invention has the following beneficial effects:

[0034] 1. The present invention is the first to design a closed heating tobacco device with a cigarette locking device. The sealing assembly includes a sealing sleeve and a driving device. On the one hand, it can lock the cigarette during the smoking process to prevent the cigarette from moving or falling. On the other hand, when smoking, the sealing sleeve seals the air passage in the cigarette accommodating cavity, so that the outside air only enters the cigarette from the side wall through hole without passing through the tobacco segment. Smoke will be generated inside the tobacco segment to replace the original air, which can reduce the oxygen content of the tobacco segment. Therefore, the heating temperature can be increased to release the tobacco flavor more fully.

[0035] 2. The cigarette locking device of the present invention is easy to operate and only includes a sealing sleeve and a driving device. The sealing sleeve can be composed of two parts, which are respectively connected to the driving device. The connection method can be gear connection, which is convenient to manufacture and operate and does not increase the complexity of smoking.

[0036] 3. The smoking device of the present invention adopts a closed cigarette locking heating method, and utilizes the Venturi effect and the Coanda effect to simplify the design of the airflow channel so that the airflow channel does not pass through the interior of the smoking device. In this way, there will be no condensed liquid or cigarette residue remaining inside the smoking device, making the smoking device easier to clean. BRIEF DESCRIPTION OF THE DRAWINGS
