Description

Technical Field

[0001] The invention belongs to the technical field of heated cigarettes and smoking articles, and particularly relates to a heated cigarette smoking device capable of generating non-oxygen gas and a heated cigarette. Background Art

[0002] As a harm-reducing tobacco product that takes into account both satisfaction and tobacco aroma, heated cigarettes can effectively reduce the release of harmful components in smoke and reduce harm while satisfying consumers' tobacco characteristics. Among them, electric heated cigarettes have quickly become a hot topic in the tobacco industry due to their "high technological content and high user conversion rate". Electric heated cigarettes consist of two parts: a heating device and a cigarette, and their smoking quality is determined by both.

[0003] Heated cigarettes have the product attribute of heating rather than burning. Therefore, the current baking temperature of heated cigarette products is usually 260℃-400℃. The cracking reaction of tobacco substances when heated is relatively simple, and some aroma components cannot be fully released when heated. However, if the temperature is increased blindly, the cigarette will burn or smolder, which will produce harmful substances and have a great adverse effect on the taste of the heated cigarette itself.

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

[0005] A first aspect of the present invention provides a smoking device for heating cigarettes capable of generating non-oxygen gas, the smoking device comprising:

[0006] The cigarette cup 2 has a through hole 21 on the side wall or the bottom;

[0007] The movable chamber 5 is arranged outside the cigarette cup 2 and contacts the bottom or the side of the bottom of the cigarette cup 2. Solid substances 6, liquid substances or solid-liquid mixtures that can generate non-oxygen gas when heated are placed therein. The surface of the movable chamber 5 that contacts the cigarette cup 2 is provided with air holes 51 that are in airflow communication with the through holes 21 of the cigarette cup 2.

[0008] The movable chamber 5 can also be drawn out from the suction device so that substances can be added therein at any time after one use.

[0009] Preferably, the solid substance 6 is ammonium bicarbonate, or a mixture of sodium nitrite and ammonium chloride.

[0010] The solid substance, liquid substance, or solid-liquid mixture is a substance that can generate non-oxygen, non-toxic, and non-hazardous gas when heated, such as nitrogen dioxide or nitrogen gas when heated.

[0011] When the solid substance is bicarbonate such as sodium bicarbonate or calcium bicarbonate, it can generate non-oxygen gas carbon dioxide when heated.

[0012] When the solid substance is a mixture of sodium nitrite and ammonium chloride, it can generate non-oxygen gas nitrogen when heated.

[0013] Preferably, the suction device further comprises: a movable cigarette sealing element 22 arranged at the upper end of the cigarette cup 2 .

[0014] After the cigarette is inserted, the cigarette cup starts to heat up, and the solid material generates non-oxygen gas when heated, and then the cigarette sealing element is used to seal the gap between the cigarette cup and the cigarette to prevent oxygen from flowing in. The cigarette sealing element can use any existing suitable sealing element, such as a sealing ring.

[0015] Preferably, the bottom of the cigarette cup 2 and the positions around the non-through holes 21 are sealed.

[0016] The second aspect of the present invention provides a heated cigarette capable of generating non-oxygen gas, wherein the heated cigarette comprises: the solid substance 6 capable of generating non-oxygen gas by heating as described in the above-mentioned suction device.

[0017] Preferably, the solid substance 6 is ammonium bicarbonate, or a mixture of sodium nitrite and ammonium chloride, or copper oxide particles, or iron oxide particles.

[0018] Preferably, the solid material 6 is arranged at the uppermost part of the heated cigarette. When inhaling, the flow direction of the smoke is from the upstream to the downstream of the cigarette.

[0019] Preferably, the solid material 6 is arranged in the tobacco segment of the heated cigarette. Copper oxide or iron oxide particles are added to the tobacco segment, and when the tobacco material is heated, it is carbonized to generate carbon, which then reacts with copper oxide or iron oxide to form corresponding metal elements and carbon dioxide. At the same time, the copper oxide or iron oxide particles can react with carbon monoxide that is not fully carbonized by heating the tobacco, thereby reducing the harm of carbon monoxide to the human body.

[0020] The above technical solutions can be freely combined under the premise of no contradiction.

[0021] The present invention has the following beneficial effects:

[0022] 1. The present invention provides for the first time a heating cigarette smoking device capable of producing non-oxygen substances. A movable chamber is provided at the bottom of the cigarette cup, in which a substance capable of producing non-oxygen gas is placed. When the cigarette cup is heated, non-oxygen gas can be produced to discharge oxygen from the cigarette cup and the cigarette. Then the cigarette cup is sealed and the cigarette is heated in an oxygen-free / low-oxygen environment. This can increase the ignition point of the smoking product, raise the heating temperature, enhance the baking intensity, and produce an aerosol with a more mellow aroma.

[0023] 2. The present invention also provides a heated cigarette capable of producing non-oxygen substances, wherein the substance capable of producing non-oxygen gas is arranged at the upstream end of the cigarette or in the tobacco section. When the cigarette is heated, the non-oxygen gas discharges the oxygen in the cigarette cup and the cigarette, and then the cigarette cup is sealed to heat the cigarette in an oxygen-free / low-oxygen environment. This can also increase the ignition point of the smoking product, raise the heating temperature, and enhance the baking intensity, so that it produces an aerosol with a more mellow aroma.

[0024] 3. In the preferred technical solution of the present invention, the solid material disposed in the tobacco section of the cigarette is a metal oxide. When the tobacco material is heated, it is carbonized to generate carbon, which then reacts with the metal oxide to form the corresponding metal element and carbon dioxide. At the same time, the metal oxide can react with the carbon monoxide that is not fully carbonized by heating the tobacco, thereby reducing the harm of carbon monoxide to the human body.

[0025] 4. The present invention starts the non-oxygen gas release process only by the heating process of the heating cup, has a simple mechanical structure and is easy to manufacture. When sucking, no additional operation such as suction is required. BRIEF DESCRIPTION OF THE DRAWINGS
