Description

Technical Field

[0001] The utility model relates to the technical field of novel tobaccos, in particular to a self-installable heated cigarette. Background Art

[0002] Adding bursting beads to the filter rod can increase the amount of aroma, improve the quality of smoke, reduce irritation, and promote soft and comfortable smoke. The aroma substances that have not been burned and pyrolyzed are safer, and the aroma adjustment method is easier to control in terms of process. However, the current bursting bead heated cigarettes on the market are only paired with one flavor of bursting beads. Consumers cannot match bursting beads according to their personal taste preferences, and consumption lacks personalization. In addition, if tobacco companies match bursting beads of different flavors in heated cigarettes and make sure that the flavors of the bursting beads in each pack of cigarettes are consistent, the process is more complicated. In the prior art, a cigarette holder shell is often used in conjunction with bursting beads. When smoking, it is necessary to add the flavor bursting beads to the cigarette holder shell, and then put it on the filter rod part of the heated cigarette for smoking. For users, every time they smoke a heated cigarette, they need to carry the cigarette holder shell component, which is inconvenient when going out.

[0097] The detailed features and advantages of the present invention are described in detail in the specific implementation modes below, and the content is sufficient to enable any technical personnel in this field to understand the technical content of the present invention and implement it accordingly. According to the description, claims and drawings disclosed in this specification, the technical personnel in this field can easily understand the relevant purposes and advantages of the present invention.

[0098] It should be noted that in this specification, similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined and explained in the subsequent drawings.

[0099] In the description of this embodiment, it should be noted that the terms "upper", "lower", "inner", "bottom", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, or are the orientations or positional relationships in which the product is usually placed when in use. They are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model.

[0100] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0101] like Figures 1 to 3 The utility model is shown in an embodiment, a self-installable heating cigarette, including a filter rod and a cigarette 1, the filter rod includes a first filter rod 2, a hollow filter rod 3 and a second filter rod 4, the first filter rod 2, the hollow filter rod 3 and the second filter rod 4 are all made of acetate fiber bundles. The first filter rod 2 and the hollow filter rod 3 are detachably connected, the hollow filter rod 3 and the second filter rod 4 are fixedly connected, the other end of the second filter rod 4 is fixedly connected to the cigarette 1, a plurality of sharp needles 5 are fixedly installed on one side of the first filter rod 2 close to the hollow filter rod 3, the sharp needles 5 penetrate the hollow filter rod 3 and are inserted into the second filter rod 4, and the internal chamber of the hollow filter rod 3 can contain explosive beads 6.

[0102] The second filter rod 4 is made of a special structure of grooved pure fiber paper capsule acetate fiber tow filter element. In simple terms, Figure 4 As shown, the outer periphery of the acetic acid filter element 41 is firstly coated with a layer of grooved cellulose paper 42, and then the whole is wrapped with a layer of forming paper 43. Figure 5 As shown, the surface of the grooved cellulose paper 42 is composed of continuously distributed groove segments 421, or the grooved cellulose paper 42 can also be composed of a combination of groove segments 421 and flat segments, which can effectively reduce the inhalation resistance and improve the sense of permeability on the one hand, and increase the contact surface area between the smoke and the filter rod on the other hand, quickly reduce the smoke temperature and increase the filtration and adsorption of harmful substances in the smoke.

[0103] Specifically, the hollow part of the hollow filter rod 3 can be made of crepe paper to form a hollow shape. Because it has a regular cavity, a low-pressure channel is formed. The flow direction of the smoke during inhalation is along the axial direction of the cigarette 1, passing through the cigarette 1, the second filter rod 4, the hollow filter rod 3 and the first filter rod 2 in sequence, so that the suction resistance during inhalation is small, which can significantly improve the filtration efficiency of tar in the smoke and effectively reduce the release of tar and carbon monoxide.

[0104] Specifically, as shown in Figure 6, the hollow part of the hollow filter rod 3 can be filled with bursting beads 6, and the bursting beads 6 are stacked and arranged in the hollow filter rod 3 as the number increases. A number of sharp needles 5 are regularly or irregularly distributed and fixed on the connecting seat 21 of the first filter rod 2.

[0105] Furthermore, the structure of the sharp needle 5 is as follows Figure 7 As shown, the two ends of the sharp needle 5 include a small head portion 52 and a connecting portion 53. The connecting portion 53 is fixedly connected to the connecting seat 21 of the first filter rod 2. The small head portion 52 of the sharp needle 5 enters the hollow filter rod 3 to pierce the bursting bead 6, and then can be inserted into the acetate filter element 41 of the second filter rod 4, so that the sharp needle 5 is positioned under the extrusion force of the acetate filter element 41, and the connection between the first filter rod 2 and the hollow filter rod 3 is completed for subsequent heating of the cigarette for inhalation. As another embodiment, after the sharp needle 5 enters the hollow filter rod 3 and pierces the bursting bead 6, it can also penetrate the second filter rod 4 to extend to the inside of the cigarette 1. Then, the sharp needle 5 can be positioned under the extrusion force of the acetate filter element 41 and the solid cigarette 1 at the same time, further increasing the stability of the connection between the first filter rod 2 and the hollow filter rod 3.

[0106] Preferably, a plurality of textured protrusions 51 are distributed on the surface of the sharp needle 5, wherein the textured protrusions 51 can form a symmetrical or asymmetrical pattern to increase the friction between the sharp needle 5 and the acetic acid filter element 41, thereby preventing the sharp needle 5 from falling off.

[0107] Furthermore, the sharp needles 5 may be irregularly distributed, and the positions where the sharp needles 5 are pulled out and reinserted into the second filter rod 4 may not be the same.

[0108] Further, such as Figure 8 As shown, the sharp needle 5 and the first filter rod 2 are fixedly connected to form an assembly. A connection seat 21 is provided at one end of the first filter rod 2 close to the hollow filter rod 3, and the connection portion 53 is fixedly mounted on the connection seat 21. The diameter of the connection seat 21 matches the inner diameter of the hollow filter rod 3, so when the sharp needle 5 enters the hollow filter rod 3 to pierce the bursting bead 6, the connection seat 21 can be completely embedded in the hollow filter rod 3, and the side of the connection seat 21 abuts against the hollow filter rod 3, further increasing the mutual connection and positioning effect between the first filter rod 2 and the hollow filter rod 3, and preventing the first filter rod 2 from loosening during the suction use process.

[0109] The working principle of this patent is as follows: when the heated cigarette of this patent leaves the factory, no bursting beads 6 are added to the hollow filter rod 3. When smoking, the user can pull out the sharp needle 5 from the hollow filter rod 3 by grabbing the first filter rod 2, and then can choose the flavor of the bursting beads 6 according to preference, such as fruity, floral, woody, spicy, medicinal bursting beads, etc. The bursting beads 6 are added to the hollow filter rod 3, and then the assembly of the first filter rod 2 and the sharp needle 5 is inserted into the hollow filter rod 3 until the exposed part of the sharp needle 5 enters the hollow filter rod 3 and stops. At this time, the small head part 52 of the sharp needle 5 is inserted into the second filter rod 4 or further inserted into the cigarette 1, and the extrusion force of the acetate filter element 41 of the second filter rod 4 is applied, and the friction between the sharp needle 5 and the acetate filter element 41 is increased by the textured protrusion 51, so as to prevent the sharp needle 5 from falling off in the acetate filter element 41, so that the first filter rod 2 and the hollow filter rod 3 are stably connected together. At the same time, when the sharp needle 5 is inserted into the hollow filter rod 3, the bursting bead 6 inside the hollow filter rod 3 will be punctured, and the aroma substance will penetrate into the hollow filter rod 3 and the second filter rod 4. When smoking a cigarette, the aroma of the bursting bead 6 is exposed to the smoke passing through the hollow filter rod 3 and the second filter rod 4, and the aroma style expected by consumers is transferred to the smoke components, thereby meeting the personalized needs of smokers.
