Description

Technical Field

[0001] The present application belongs to the field of cigarette filters, and in particular to a multi-component composite filter with controllable tar amount. Background Art

[0002] Cigarette products are usually made of tobacco segments and filters wrapped with tipping paper. Among them, tobacco segments are usually prepared by wrapping uniformly filled shredded fillers with forming paper, and filters are usually prepared by wrapping filament bundles with forming paper. Smokers use cigarette products by lighting one end of the cigarette product and burning the tobacco rods, and then receive mainstream smoke by inhaling at the filter end of the cigarette product. Tar is one of the components in the smoke produced by the burning of cigarettes. It contains many organic compounds, which not only affect the aroma perception of cigarettes to a certain extent, but also are related to various health problems. Therefore, cigarettes are required to have the characteristics of healthy low tar, moisturizing and high aroma. The existing cigarette filters on the market basically cannot adjust the tar, and different smokers have different requirements for the taste and amount of smoke.

[0003] Patent application number 201320117814.4 discloses a cigarette that adjusts the tar transfer amount by rotating the filter, including a filter rod and a cigarette segment. The filter rod is wrapped with more than two layers of shaping paper, and each layer of shaping paper is separately bonded by overlapping glue. The shaping papers can slide against each other. The innermost layer of shaping paper is perforated along the longitudinal direction of the filter rod. Before smoking, the shaping paper and the bonded tipping paper are torn off along the cutting line, and the upper half of the filter rod can slide freely. Sliding it away from the cigarette segment, the more holes are exposed, the higher the ventilation and dilution efficiency, and the lower the tar. This cigarette structure has a complex structural design. The outer layer of shaping paper needs to be torn off when smoking, which is cumbersome to operate. The shaping paper may be torn, resulting in the inability to adjust the tar, and the production cost is high. It can be seen that the existing technology needs to be further improved and enhanced.

Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0023] In the description of the present invention, it is necessary to understand that the terms "center", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "axial", "radial", "circumferential" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying 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 present invention. In the present invention, unless otherwise clearly specified and limited, a first feature being "upper" or "lower" than a second feature may be the first and second features directly contacting, or the first and second features indirectly contacting through an intermediate medium.

[0024] In the present utility model, unless otherwise clearly specified and limited, 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 one; 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. However, if it is indicated as a direct connection, it means that the two connected bodies are not connected through an intermediate structure, but are connected to form a whole only through a connecting structure. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to the specific circumstances.

[0025] In the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features.

[0026] The utility model is described below in conjunction with the accompanying drawings.

[0027] The specific plans adopted are:

[0028] like Figure 1-3 As shown, the utility model provides a multi-component composite filter with variable tar amount control, including a filter rod and a shaping paper wrapped outside the filter rod, the filter rod includes a near-tobacco segment 10, a filter middle segment 11 and a filter mouth segment 12, the filter middle segment 11 and the filter mouth segment 12 are respectively provided with a first channel 110 and a second channel 120, one end of the filter middle segment 11 is fixedly connected to the near-tobacco segment 10, and the other end is rotatably connected to the filter mouth segment 12, and rotating the filter mouth segment 12 can change the overlapping area of ​​the first channel 110 and the second channel 120 to adjust the amount of air passing therethrough and change the tar amount.

[0029] The multi-component composite filter with variable controllable tar amount of the utility model is obtained by dividing the filter rod into three sections, and providing a first channel 110 and a second channel 120 in the filter middle section 11 and the filter mouth section 12 respectively. The overlapping area of ​​the first channel 110 and the second channel 120 can be changed by rotating the filter mouth section 12. When the overlapping area of ​​the channels increases, the cross-sectional area of ​​the airflow through the channels will also increase, thereby increasing the airflow rate; conversely, when the overlapping area of ​​the channels decreases, the airflow rate will also decrease. This flexible adjustment feature enables the airflow rate to be accurately adjusted by rotating the filter mouth section, thereby meeting the user's requirements for airflow rate changes in actual applications.

[0030] As a preferred embodiment of the present application, the first channel 110 and the second channel 120 have different cross-sectional shapes. Specifically, the cross-sectional shape of the first channel 110 is heart-shaped, and the cross-sectional shape of the second channel 120 is pentagonal. The cross-sectional shape of the heart-shaped channel is heart-shaped, that is, the two sides are arc-shaped and concave inward and meet in the center to form a sharp angle. The cross-sectional shape of the five-pointed star channel is composed of five sides, presenting a pentagon. When the smoke flows in the heart-shaped channel, due to the presence of the sharp angles, the smoke will experience impact and vortex phenomena. The special shape of the five-pointed star channel can cause the fluid to produce a multi-way diversion effect in the channel. When the smoke enters the five-pointed star channel, due to the change in the shape of the channel, the smoke flows along different edges, thereby realizing the diversion of the smoke. The heart-shaped channel and the five-pointed star channel can achieve flow rate and flow rate regulation to a certain extent.

[0031] As a preferred embodiment of the present application, the cross-sectional shape of the first channel 110 and the second channel 120 is the same, such as an arc shape, and rotating the filter mouth segment 12 can make the first channel and the second channel completely staggered, partially overlapped, or completely overlapped.

[0032] To achieve rotation, see Figure 2 and Figure 3 In this embodiment, an annular plug-in groove 111 is provided at the end of the filter middle section 11, and an annular plug-in portion 121 is provided at the end of the filter mouth section 12. The annular plug-in groove 111 and the annular plug-in portion 121 are matched and connected, and the annular plug-in portion 121 can rotate in the annular plug-in groove 111. The first channel 110 is provided on the inner side of the annular plug-in groove 111, and the second channel 120 is provided on the inner side of the annular plug-in portion 121. Specifically, the annular plug-in portion includes a large end diameter ring 1210 and a small end diameter ring 1211. The small end diameter ring 1211 The ring width is smaller than the ring width of the annular insertion groove 111, and the ring width of the large end diameter ring 1210 is greater than or equal to the ring width of the annular insertion groove 111. When in use, the large end diameter ring 1210 of the filter mouth segment 12 can be first pulled out of the annular insertion groove 111, and then the small end diameter ring 1211 can be rotated in the annular insertion groove 111 to adjust the overlapping area of ​​the first channel 110 and the second channel 120 to form channels of different shapes and sizes, adjust the airflow during single-puff smoking of the cigarette, and thus adjust the tar amount, so that the user can feel the difference in sensory quality when smoking.

[0033] As a preferred embodiment of the present application, the tobacco-proximal segment 10 is an ordinary acetate filter rod, and the filter middle segment 11 and the filter mouth segment 12 are Collins filter rods. The Collins filter rod is made of high-efficiency filtering materials and a special process, has a special structure and high hardness, has a large filtering area and a high-efficiency filtering effect, and is suitable for opening annular plug-in grooves and channels. After the annular plug-in portion is pulled out of the annular plug-in hole, the annular plug-in portion can maintain its shape for easy insertion back into the annular plug-in groove, which is convenient for user operation.
