Description

Technical Field

[0001] The utility model relates to the technical field of cigarettes, in particular to a heat-not-burn cigarette filter rod. Background Art

[0002] As a new tobacco product, heat-not-burn cigarettes heat tobacco substances through heating elements. When the temperature reaches about 300°C, the tobacco substances are atomized into aerosols by high temperature. The aerosols enter the mouth directly through the filter tip. In order to achieve a sufficient aerosol experience, the filter material is required to minimize the adsorption of aerosols, so the length of the filter material is limited. Therefore, the smoke of heat-not-burn cigarettes is currently heavier.

[0003] In view of the above problems, the inventor of the present invention finally obtained the present invention after a long period of research and practice. Utility Model Content

[0012] Furthermore, a smoke channel is provided inside the filter rod inlet section, and the smoke channel extends axially and is communicated with the inner cavity of the hollow section of the filter rod.

[0013] Furthermore, the filter rod substrate segment includes a winding paper layer and a cooling filter element, the winding paper layer surrounds the outer circumference of the cooling filter element and is bonded to the cooling filter element; the outer circumferential surface of the cooling filter element is evenly provided with a plurality of cooling grooves extending axially, and an axially extending supporting convex strip is formed between two adjacent cooling grooves.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] The utility model can make cigarette smoke more fresh by arranging an annular shell for filling smoke freshening particles in the cigarette filter rod. The smoke freshening particles are preferably pine mushroom particles, which can not only make the smoke fresh, but also effectively release the pine components in the pine mushroom particles after heating, so that the smoke contains the effective ingredient pine mushroom alcohol in the pine mushroom, which is beneficial to the human body and improves the user's smoking experience. Secondly, by arranging the filter rod substrate section, the smoke passes through the cooling filter element and the filter rod hollow section in turn, while reducing the smoke temperature, the beneficial components in the pine mushroom particles are released. At the same time, the cooling groove can prevent the temperature of the filter rod from being too high during smoking, causing burns to the user, thereby improving the user experience of the cigarette.

[0019] The above and other technical features and advantages of the present invention are described in more detail below in conjunction with the accompanying drawings.

[0020] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0021] In the present invention, unless otherwise clearly defined and specified, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0022] like Figure 1 , Figure 2 As shown, a heat-not-burn cigarette filter rod comprises a filter rod inlet section 1, a filter rod hollow section 2 and a filter rod substrate section 3. The bottom end of the filter rod inlet section 1 is fixedly connected to the top end of the filter rod hollow section 2, the bottom end of the filter rod hollow section 2 is fixedly connected to the top end of the filter rod substrate section 3, and the bottom end of the filter rod substrate section 3 is connected to the tobacco section 4. The filter rod hollow section 2 comprises an annular shell 21, and a cavity is provided at the center of the annular shell 21, and the cavity is used to fill smoke freshening particles 22. A smoke channel 11 is provided inside the filter rod inlet section 1, and the smoke channel 11 extends axially and communicates with the inner cavity of the filter rod hollow section 2.

[0023] The heating element heats the tobacco. The aerosol enters the oral cavity through the filter rod substrate section 3, the filter rod hollow section 2, and the filter rod inlet section 1 in sequence. Since the annular shell 21 of the filter rod hollow section 2 contains smoke freshening particles 22, the cigarette smoke can be made fresher. It can be understood that the smoke freshening particles 22 can contain spices, plant ingredients, etc., and can emit a fresh smell when heated, such as mint, orange, etc.

[0024] In a preferred embodiment, the smoke freshening particles 22 contain matsutake ingredients. Matsutake mushrooms, also known as pine mushrooms, are rich in nutrients and have high medicinal value. They contain 17% crude protein, 5.8% crude fat, 61.5% soluble nitrogen-free compounds, and are rich in vitamins B1, B2, C, calcium niacin, phosphorus, iron, etc. Matsutake mushrooms contain medicinal ingredients such as matsutake alcohol and isotrichol, which have the effects of strengthening the body, benefiting the stomach, relieving pain, regulating qi and resolving phlegm, and expelling insects. Matsutake contains "matsutake polysaccharides" with anti-tumor activity, which can improve the body's own immunity and have anti-tumor, antibacterial, antiviral, antifungal, anti-diabetic, and anti-inflammatory effects. After heating, the matsutake particles can not only make the smoke fresher, but also make the smoke contain matsutake alcohol, an effective ingredient in matsutake, which is beneficial to the human body and enhances the user's smoking experience.

[0025] More preferably, the Matsutake particles are freeze-dried particles with a single particle mass of 0.05 g to 0.1 g, a particle size of 20 to 40 mesh, a moisture content of 5% to 12%, and a powder content ≤8%.

[0026] In a specific embodiment, one side of the annular shell 21 is bonded to the filter rod inlet section 1, and the matsutake particles are embedded in the middle position of the inner cavity of the annular shell 21. The filter rod substrate section 3 includes a paper layer 31 and a cooling filter element 32, and the paper layer 41 surrounds the outer periphery of the cooling filter element 32 and is bonded to the cooling filter element 42. The joint between the paper layer 31 and the tobacco section 4 forms a flat surface. The outer peripheral surface of the cooling filter element 42 is evenly provided with a plurality of cooling grooves 321 extending axially, and an axially extending supporting convex strip 322 is formed between two adjacent cooling grooves 43. By providing the filter rod substrate section 3, the smoke passes through the cooling filter element and the hollow section of the filter rod in turn, and while reducing the smoke temperature, the beneficial components in the particles are released. At the same time, the cooling groove can prevent the temperature of the filter rod from being too high during smoking, causing burns to the user, thereby improving the user experience of traditional cigarettes.

[0027] The above are only preferred embodiments of the present invention, which are only illustrative and not restrictive. The structures and connection modes of the components in the present invention can be changed, and any equivalent transformations and improvements based on the technical solution of the present invention should not be excluded from the protection scope of the present invention.
