Description

Technical Field

[0001] The invention belongs to the technical field of cigarette matching equipment, and particularly relates to an adjustable flavor adding device for cigarettes. Background Art

[0002] As people pay more and more attention to the safety of tobacco products, the tobacco industry has made many efforts to reduce the amount of tar and CO in cigarette smoke. Among them, the radial opening of a number of tiny micropores in the filter of a cigarette can effectively reduce the amount of tar and CO in the smoke. Such cigarettes are already available in large quantities on the market.

[0003] Conventional smoking products usually only have a single flavor. To address this limitation, popping beads that can be pinched by smokers are added to the filter to change the flavor of the smoke during the inhalation process. However, after the popping beads are pinched, the flavor concentration in the cigarette cannot be changed according to the user's needs, and the user's diverse needs cannot be met.

[0004] Based on the above-mentioned cigarettes with a plurality of tiny micropores radially opened on the filter, our company has developed an adjustable flavor adding device to add a specific concentration of flavor to the cigarette according to user needs. Summary of the Invention

[0005] The purpose of the present invention is to provide an adjustable flavoring device for cigarettes, which, by moving a flavoring ring, enables different numbers of flavor outlet holes to correspond to the connecting slot holes, thereby controlling the amount of flavor gas that evaporates from the flavor extract on the filler and enters the cigarette through the flavor outlet holes, the connecting slot holes and the tiny micropores for the user to inhale, thereby achieving the purpose of adjusting the flavor concentration in the cigarette. The device has a simple structure and is easy to adjust.

[0006] In order to achieve the above technical objectives, the technical solutions adopted by the present invention are as follows:

[0007] An adjustable flavoring device for cigarettes, comprising a fixed ring and a flavoring ring movably mounted on the fixed ring, wherein a cavity is provided in the flavoring ring, wherein a filler contaminated with a flavor extract is provided in the cavity, wherein the inner wall of the flavoring ring is provided with a plurality of hole groups, wherein each hole group comprises a plurality of flavor outlet holes, wherein the flavor outlet holes are connected to the cavity, wherein the upper end surface of the flavoring ring is provided with a plurality of air inlet holes, wherein the air inlet holes are connected to the cavity, and wherein the inner wall of the fixed ring is provided with connecting slots at positions corresponding to the hole groups.

[0008] The aroma holes in each hole group are spirally arranged on the inner wall of the aroma ring, the inner wall of the aroma ring being provided with a strip groove, and the outer wall of the fixed ring being fixedly provided with a guide bar. The strip groove and the guide bar are both spirally arranged, and the pitch of the spiral line containing the aroma holes in each hole group is the same. This structural design allows the guide bar to be located within the strip groove during use. By rotating the aroma ring, the number of aroma holes connected to the connecting slots can be adjusted, thereby achieving the purpose of adjusting the aroma concentration in the cigarette, and providing more convenient use.

[0009] It is further defined that a retaining ring is fixedly provided on the outer wall of the upper end of the fixing ring, and a convex ring is integrally formed below the retaining ring on the upper end of the fixing ring, and a first external thread is provided on the convex ring. An annular groove is provided on the inner wall of the upper portion of the flavoring ring, and a first internal thread is provided on the inner wall of the annular groove. Before the flavoring ring is screwed onto the first external thread of the fixing ring via the first internal thread, the guide bar is disengaged from the strip groove. With this structural design, after flavoring the cigarette, the flavoring ring can be further rotated upward to disengage the guide bar from the strip groove. Then, by mutually screwing the first internal thread and the first external thread, the top of the flavoring ring is pressed against the retaining ring, and the retaining ring is used to complete the sealing of the air inlet, thereby preventing the flavor extract in the flavoring ring from evaporating and leaking from the air inlet when the adjustment and addition device is not in use.

[0010] It is further defined that the lower end surface of the retaining ring is inlaid with a sealing ring. Such a structural design, when the retaining ring is used to block the air inlet, utilizes the compression of the retaining ring and the fragrance adding ring on the sealing ring to further strengthen the sealing of the air inlet when the regulating and adding device is not used, and has a strong practicality.

[0011] Furthermore, the outer wall of the lower end of the fixing ring is provided with a second external thread, and the fixing ring is threadedly connected to the limit ring via the second external thread, wherein the pitch of the second external thread is smaller than the pitch of the helical line on which the guide strip is located. This structural design utilizes the pitch difference between the second external thread and the helical line on which the guide strip is located to restrain the lower end of the fixing ring, thereby preventing the fragrance ring from excessively moving downward during adjustment, thereby causing the fragrance ring to separate from the fixing ring.

[0012] It is further specified that the cross section of the limiting ring is L-shaped. This structural design not only limits the position of the fragrance ring by using the limiting ring to prevent the fragrance ring from excessively moving downward during the adjustment process, but also uses the limiting ring with an L-shaped cross section to adjust the maximum downward movement position of the fragrance ring on the fixed ring. Therefore, in actual use, after adjusting the fragrance ring to a desired position, the limiting ring is rotated until the top of the limiting ring abuts against the lower end surface of the fragrance ring. In this way, the next time the adjustment and addition device is used, the fragrance ring only needs to be rotated again until it abuts against the limiting ring to ensure that the fragrance concentration at this time is the same as the previous time, which is more convenient to use.

[0013] Furthermore, the outer walls of the retaining ring, the fragrance adding ring and the limiting ring are all provided with anti-slip grooves. Such a structural design facilitates the rotation of the fragrance adding ring / limiting ring and is highly practical.

[0014] Furthermore, the inner walls of the upper and lower ends of the fixed ring are fixed with ring platforms. This structural design utilizes the ring platforms to isolate the inner wall of the fixed ring from the outer wall of the cigarette. During use, the tiny pores of the cigarette are located between the two ring platforms, forming an annular space between the cigarette and the fixed ring. This prevents the inner wall of the fixed ring from directly contacting the outer wall of the cigarette, which could cause clogging of the tiny pores. This is highly practical.

[0015] The invention adopting the above technical solution has the following advantages:

[0016] 1. By moving the aroma ring, different numbers of aroma holes are aligned with the connecting slots, thereby controlling the amount of aroma gas that evaporates from the filler and enters the cigarette through the aroma holes, connecting slots, and tiny pores for the user to inhale, thereby achieving the purpose of adjusting the aroma concentration in the cigarette. The structure is simple and the adjustment is convenient.

[0017] 2. The spiral arrangement of the fragrance outlet holes, guide strips, and strip grooves allows the guide strips to be located within the strip grooves during use. By rotating the fragrance ring, the number of fragrance outlet holes connected to the connecting slots can be adjusted, thereby achieving the purpose of adjusting the fragrance concentration in the cigarette, making it more convenient to use.

[0018] 3. Through the cooperation of the retaining ring, the convex ring, the first external thread, the annular groove, and the first internal thread, after flavoring the cigarette, the flavoring ring can be further rotated upward to disengage the guide strip from the strip groove. The first internal thread and the first external thread are then screwed together, and the top of the flavoring ring is abutted against the retaining ring after the flavoring ring has sealed the flavor outlet. The retaining ring then seals the air inlet, thereby preventing the flavor extract in the flavoring ring from evaporating and leaking out of the air inlet when the adjustment and adding device is not in use.

[0019] 4. The pitch difference between the second external thread and the helical line where the guide strip is located is used to restrict the lower end of the fixed ring to prevent the fragrance ring from moving downward excessively during the adjustment process, thereby causing the fragrance ring to separate from the fixed ring.

[0037] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that in the drawings or descriptions, similar or identical parts are numbered the same. Implementations not shown or described in the drawings are forms known to those of ordinary skill in the art. In addition, directional terms mentioned in the embodiments, such as "upper," "lower," "top," "bottom," "left," "right," "front," and "back," are merely references to the directions in the drawings and are not intended to limit the scope of protection of the present invention.

[0038] like Figures 1 to 11 As shown, an adjustable flavoring device for cigarettes of the present invention comprises a fixed ring 1 and a flavoring ring 2 movably mounted on the fixed ring 1, wherein a cavity 20 is provided in the flavoring ring 2, wherein a filler contaminated with a flavor extract is provided in the cavity 20, and a plurality of hole groups are formed on the inner wall of the flavoring ring 2, each hole group comprising a plurality of flavor outlet holes 21, which are communicated with the cavity 20, a plurality of air inlet holes 22 are formed on the upper end surface of the flavoring ring 2, which are communicated with the cavity 20, and a connecting slot 11 is formed on the inner wall of the fixed ring 1 at corresponding positions of the hole groups.

[0039] The aroma holes 21 in each hole group are spirally arranged on the inner wall of the flavoring ring 2. The inner wall of the flavoring ring 2 is provided with a strip-shaped groove 23. A guide bar 12 is fixed to the outer wall of the fixed ring 1. Both the strip groove 23 and the guide bar 12 are spirally arranged, with the same pitch as the helical line of the aroma holes 21 in each hole group. During use, the guide bar 12 is located within the strip groove 23. By rotating the flavoring ring 2, the number of aroma holes 21 communicating with the connecting slots 11 can be adjusted, thereby achieving the purpose of adjusting the aroma concentration in the cigarette 10, making it more convenient to use.

[0040] A retaining ring 13 is fixedly mounted on the outer wall of the upper end of the fixing ring 1. A protruding ring is integrally formed below the retaining ring 13 at the upper end of the fixing ring 1. A first external thread 14 is formed on the protruding ring. An annular groove is formed on the inner wall of the upper portion of the flavoring ring 2. A first internal thread 140 is formed on the inner wall of the annular groove. Before the flavoring ring 2 is screwed onto the first external thread 14 of the fixing ring 1 via the first internal thread 140, the guide bar 12 is disengaged from the strip groove 23. After flavoring the cigarette 10, the flavoring ring 2 can be further rotated upward to disengage the guide bar 12 from the strip groove 23. The first internal thread 14 and the first external thread 140 are then screwed together. After the flavoring ring 2 has sealed the fragrance outlet 21, the top of the flavoring ring 2 rests against the retaining ring 13, thereby sealing the air inlet 22. This prevents the flavor extract in the flavoring ring 2 from evaporating and leaking out of the air inlet 22 when the adjustment and addition device is not in use.

[0041] The lower end surface of the baffle ring 13 is inlaid with a sealing ring 130. When the air inlet 22 is blocked by the baffle ring 13, the baffle ring 13 and the fragrance adding ring 2 squeeze the sealing ring 130, further strengthening the sealing of the air inlet 22 when the regulating and adding device is not used, and the practicality is strong.

[0042] The outer wall of the lower end of the fixing ring 1 is formed with a second external thread 30, which is threadedly connected to the limit ring 3 via the second external thread 30. The pitch of the second external thread 30 is smaller than the pitch of the helical line of the guide strip 12. This difference in pitch between the second external thread 30 and the helical line of the guide strip 12 restrains the lower end of the fixing ring 1, preventing the fragrance ring 2 from moving downward excessively during adjustment, which could cause it to detach from the fixing ring 1.

[0043] The cross section of the limiting ring 3 is L-shaped. While the limiting ring 3 is used to limit the position of the fragrance ring 2 to prevent the fragrance ring 2 from moving downward excessively during the adjustment process, the limiting ring 3 with an L-shaped cross section can be used to adjust the maximum downward movement position of the fragrance ring 2 on the fixed ring 1. Therefore, in actual use, after adjusting the fragrance ring 2 to the required position, the limiting ring 3 is rotated until the top of the limiting ring 3 abuts the lower end face of the fragrance ring 2. In this way, the next time the adjustment and addition device is used, the fragrance ring 2 only needs to be rotated again until it abuts the limiting ring 3, so that the fragrance concentration at this time can be the same as last time, which is more convenient to use.

[0044] The outer walls of the retaining ring 13, the fragrance adding ring 2 and the limiting ring 3 are all provided with anti-slip grooves, which facilitates the rotation of the fragrance adding ring 2 / limiting ring 3 and is highly practical.

[0045] Annular steps 15 are fixed to the inner walls of the upper and lower ends of the fixing ring 1. These steps 15 isolate the inner wall of the fixing ring 1 from the outer wall of the cigarette 10. During use, the tiny pores of the cigarette 10 are located between the two steps 15, creating an annular space between the cigarette 10 and the fixing ring 1. This prevents direct contact between the inner wall of the fixing ring 1 and the outer wall of the cigarette 10, which could clog the tiny pores and improves practicality.

[0046] In this embodiment, when in use, the cigarette 10 is inserted into the fixing ring 1 so that the fine micropores of the cigarette 10 are located between the two ring platforms 15;

[0047] Rotate the fragrance ring 2 so that the first external thread 14 is disengaged from the first internal thread 140 , and continue to rotate the fragrance ring 2 so that the guide strip 12 enters the strip groove 23 ;

[0048] When the cigarette 10 is lit and smoked, the outside air enters the cavity 20 through the air inlet 22, causing the flavor extract on the filler to volatilize, and the gaseous flavor to enter the annular space between the cigarette 10 and the fixing ring 1 through the flavor outlet 21 aligned with the connecting slot 11 and the connecting slot 11, and then enter the cigarette 10 through the tiny micropores of the cigarette 10 and be inhaled by the user along with the smoke generated by the burning cigarette 10.

[0049] When the fragrance concentration needs to be adjusted, the fragrance ring 2 is rotated to adjust the number of fragrance outlet holes 21 in the hole group that are aligned with the communicating slots 11.

[0050] The above describes in detail the adjustable flavoring device for cigarettes provided by the present invention. The description of the specific embodiments is intended only to facilitate understanding of the method and core concepts of the present invention. It should be noted that those skilled in the art will appreciate that various improvements and modifications may be made to the present invention without departing from the principles of the present invention, and such improvements and modifications fall within the scope of protection of the claims.
