Description

Technical Field

[0001] The present invention relates to the technical field of cigarettes, and in particular to a filter tip and a cigarette. Background Art

[0002] As the pressure of life increases, more and more people use smoking to relieve stress. During the smoking process, people also hope that the taste of the cigarette can be richer.

[0003] Traditionally, cigarette filters are provided with ventilation holes, which can dilute the smoke and reduce the temperature of the smoke, but also reduce the taste of the smoke and dilute the flavor of the smoke.

[0004] In existing cigarettes, phase change materials are filled in the air holes of the filter. When the cigarette is initially ignited, the fire source is relatively far away, so the phase change material blocks the air holes, allowing the smoke to retain its original taste. As the cigarette is ignited, the distance between the fire source and the filter becomes closer, and the phase change material undergoes phase change after being heated, allowing the air holes to exchange gas with the outside world to dilute the smoke and reduce the temperature of the smoke. Since the change process of the phase change material is irreversible and related to temperature, it cannot be freely controlled, so the change in taste is also repetitive.

[0005] Therefore, there is an urgent need for a filter tip and a cigarette to solve the above-mentioned technical problems. Summary of the invention

[0006] The purpose of the present invention is to provide a filter tip and a cigarette, so that smokers can freely adjust the concentration of the smoke they inhale according to their own preferences.

[0007] To achieve this object, the present invention adopts the following technical solutions:

[0009] Filter rod;

[0010] A shaping paper is sleeved on the outer peripheral side of the filter rod, and two shaping papers are spaced apart along the axial direction of the filter rod, and an adjustment section is formed between the two shaping papers;

[0011] An adjusting ring is provided in the adjusting section, the adjusting ring is sleeved on the outer peripheral side of the filter rod, the adjusting ring comprises a disassembly portion and a sliding portion, the disassembly portion is detachably connected to the shaping paper, the adjusting section is provided with an air permeable channel, the air permeable channel passes through the disassembly portion and the filter rod, the sliding portion can slide axially relative to the shaping paper, and can close the air permeable channel.

[0012] As a preferred technical solution of the filter tip, the disassembly portion is detachably connected to the sliding portion.

[0013] As a preferred technical solution of the filter tip, one end of the disassembly portion is discontinuously connected to one end of the sliding portion along the circumferential direction.

[0014] As a preferred technical solution of the filter tip, the disassembly portion is a strip-shaped paper member, which is circumferentially wound around the adjustment section, and a tearing protrusion is provided at one end of the disassembly portion.

[0015] As a preferred technical solution of the filter tip, a reinforcing piece is sandwiched between the disassembly portion and the shaping paper, the reinforcing piece is fixed to the disassembly portion, and one end of the reinforcing piece overlaps with the tearing protrusion.

[0016] As a preferred technical solution of the above-mentioned filter tip, the above-mentioned adjustment section is provided with a limiting groove, and the above-mentioned adjustment ring is located in the above-mentioned limiting groove.

[0017] As a preferred technical solution of the filter tip, a plurality of the air permeable channels are provided, and the plurality of air permeable channels are provided at intervals along the circumference of the adjustment section to form an air permeable ring.

[0018] As a preferred technical solution of the filter, the adjustment section is provided with a plurality of the air-permeable rings, which are spaced apart along the axial direction of the adjustment section, and the sliding portion can selectively close one or more of the air-permeable rings.

[0019] As a preferred technical solution of the above filter tip, the above air permeable channel is punched by laser.

[0021] Beneficial effects of the present invention:

[0022] The present application provides a filter tip, comprising a filter rod, a shaping paper and an adjustment ring. The shaping paper is sleeved on the outer peripheral side of the filter rod, and two shaping papers are arranged at intervals along the axial direction of the filter rod, and an adjustment section is formed between the two shaping papers; in the adjustment section, the adjustment ring is sleeved on the outer peripheral side of the filter rod, and the adjustment ring comprises a disassembly part and a sliding part, the disassembly part is detachably connected to the shaping paper, and the adjustment section is provided with a ventilation channel, which runs through the disassembly part and the filter rod, and the sliding part can slide relative to the shaping paper along the axial direction and can close the ventilation channel.

[0023] Specifically, when the cigarette holder is maintained in its factory state, the adjustment ring remains stationary in the axial direction relative to the shaping paper in the adjustment section, so that the ventilation channel remains unobstructed; when the smoker wishes to change the smoking concentration of the cigarette, the disassembly portion can be removed from the peripheral side of the shaping paper, so that the sliding portion obtains space to move in the axial direction, and in the space, the sliding portion can switch between the first position and the second position. When the sliding portion moves to the first position, the sliding portion avoids the ventilation channel to keep the ventilation channel unobstructed, so that the smoker can still taste the smoke of normal concentration.

A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0035] In the description of this embodiment, the terms "upper", "lower", "right", etc., directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplification of operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0036] like Figures 1 to 3 As shown, the present application provides a filter 10, including a filter rod 13, a shaping paper 11 and an adjustment ring 12. The shaping paper 11 is sleeved on the outer peripheral side of the filter rod 13, and two shaping papers 11 are arranged at intervals along the axial direction of the filter rod 13, and an adjustment section is formed between the two shaping papers 11; in the adjustment section, the adjustment ring 12 is sleeved on the outer peripheral side of the filter rod 13, and the adjustment ring 12 includes a disassembly portion 121 and a sliding portion 122, and the disassembly portion 121 is detachably connected to the shaping paper 11, and the adjustment section is provided with a ventilation channel 123, which runs through the disassembly portion 121 and the filter, and the sliding portion 122 can slide relative to the shaping paper 11 along the axial direction and can close the ventilation channel 123.

[0037] Specifically, when the cigarette holder is maintained in its factory state, the adjustment ring 12 remains stationary in the axial direction relative to the shaping paper 11 in the adjustment section, so that the air permeable channel 123 remains unobstructed; when the smoker wishes to change the smoking concentration of the cigarette, the disassembly portion 121 can be removed from the peripheral side of the shaping paper 11, so that the sliding portion 122 obtains space to move in the axial direction, and in the space, the sliding portion 122 can switch between the first position and the second position. When the sliding portion 122 moves to the first position, the sliding portion 122 avoids the air permeable channel 123 to keep the air permeable channel 123 unobstructed, so that the smoker can still taste the normal concentration of smoke. When the sliding portion 122 moves to the second position, the sliding portion 122 covers the end face of the air permeable channel 123 opened on the filter rod 13 to block the air permeable channel 123. In this way, the ventilation rate of the filter 10 is reduced and the concentration of the smoke inhaled by the smoker is increased.

[0038] In this way, smokers can freely adjust the concentration of the smoke they inhale according to their own preferences.

[0039] Optionally, the disassembly portion 121 is detachably connected to the sliding portion 122. This arrangement allows the disassembly portion 121 to be completely separated from the filter 10, making the structure of the filter 10 neat and tidy, and convenient for the smoker to hold.

[0040] In other embodiments, the disassembly and washing part is fixedly connected to the sliding part 122 . After the disassembly part 121 is detached from the peripheral side of the forming paper 11 , it can be turned toward the side where the sliding part 122 is located, freeing up sliding space for the sliding part 122 to block the air permeable channel 123 .

[0041] Optionally, one end of the disassembly portion 121 is intermittently connected to one end of the sliding portion 122 along the circumferential direction. This arrangement weakens the connection strength between the disassembly portion 121 and the sliding portion 122, making it easier for the two to be disengaged.

[0042] Optionally, the disassembly portion 121 is a strip of paper, which is wound around the adjustment section along the circumferential direction, and a tearing protrusion 1211 is provided at one end of the disassembly portion 121. With this arrangement, the paper material is lighter and cheaper than other materials. When disassembling, the disassembly portion 121 can be removed by simply holding the tearing protrusion 1211 and rotating it in the opposite direction of the winding of the disassembly portion 121.

[0043] Optionally, a reinforcing piece 1212 is sandwiched between the disassembly portion 121 and the forming paper 11, the reinforcing piece 1212 is fixed to the disassembly portion 121, and one end of the reinforcing piece 1212 overlaps with the tearing protrusion 1211. In this way, during the disassembly process, the reinforcing piece 1212 bears the pulling force, and the reinforcing piece 1212 rotates in the opposite direction of the winding direction against the disassembly portion 121, so as to prevent the disassembly portion 121 from breaking during the tearing process, and the remaining part is difficult to disassemble.

[0044] Optionally, the adjustment section is provided with a limiting groove, and the adjustment ring 12 is located in the limiting groove. In this way, in the exit state, the adjustment ring 12 is limited in the limiting groove and remains relatively still with the forming paper 11 in the axial direction. After the disassembly part 121 is removed, the sliding part 122 also moves only in the limiting groove, which is easy to control.

[0045] Optionally, there are multiple air passages 123, and the multiple air passages 123 are spaced apart along the circumference of the adjustment section to form an air ring. This arrangement enables the sliding portion 122 to simultaneously close multiple air passages 123 and prevent the adjustment ring 12 from becoming ineffective after one of the air passages 123 is blocked.

[0046] Optionally, the adjustment section is provided with a plurality of air permeable rings, which are spaced apart along the axial direction of the adjustment section, and the sliding portion 122 can selectively close one or more air permeable rings. In this way, the sliding portion 122 blocks different numbers of air permeable rings to form multiple levels of concentration for smokers to choose.

[0047] Optionally, the air permeable channel 123 is punched by laser.

[0048] The present application also provides a cigarette, comprising a tobacco segment 20 and the above-mentioned filter 10, the tobacco segment 20 comprises cigarette paper and tobacco, the cigarette paper is connected end to end to form a accommodating space, the tobacco is placed in the accommodating space, and the filter 10 is connected to one end of the tobacco segment 20 through the tipping paper.

[0049] Furthermore, the data obtained in the experiment are shown in the following table:

[0050]

[0051] The average draw resistance of a normal cigarette after perforation is 926 Pa, and the average total ventilation rate is 33.7%; after the sliding portion 122 covers the position of the ventilation channel 123, the average draw resistance becomes 1117 Pa, and the average total ventilation rate becomes 6.4%.

[0052] Furthermore, in the experiment, the following data can be obtained:

[0053]

[0054] The flavor concentration of a cigarette is determined by the amount of tar, nicotine and carbon monoxide in the smoke. It is known from test data that when the sliding portion 122 is in the second position, the concentrations of the above three substances in the cigarette increase significantly, so that the smoker can wait until the sliding portion 122 is in the first position to enjoy a stronger flavor of smoke.

[0055] In addition, the above are only preferred embodiments of the present invention and the technical principles used. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and that various obvious changes, readjustments and substitutions can be made by those skilled in the art without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in more detail through the above embodiments, the present invention is not limited to the above embodiments, and may include more other equivalent embodiments without departing from the concept of the present invention, and the scope of the present invention is determined by the scope of the appended claims.
