Description

Technical Field

[0001] The utility model relates to the technical field of tobacco manufacturing, in particular to a cigarette material can sealing ring. Background Art

[0002] During the cigarette manufacturing process, it is necessary to add flavors to the tobacco, and the flavors are generally stored inside the material tank. Since the flavors are highly volatile, the material tank needs to be sealed. A round hole is formed on a flat plate on one side of the material tank, and the flavors can be poured in or out along the round hole. A plug-in is plugged into the round hole. The plug-in consists of a plug-in cover and a plug-in tube. A plug-in tube is formed on the lower side of the plug-in cover. The plug-in tube is plugged into the round hole. A sealing ring is sleeved on the outside of the plug-in tube. The sealing ring abuts between the plug-in tube and the round hole. When the plug-in tube is plugged into the round hole, the plug-in cover abuts against the flat plate around the round hole.

[0003] However, the sealing plug in the prior art has a rectangular cross-section and is sleeved on the plug-in tube. Due to its small cross-sectional area, if fatigue deformation occurs in part of the sealing ring, the risk of breaking the entire sealing ring will occur. In addition, since the sealing ring seals the material tank through extrusion deformation between the plug-in tube and the circular hole, the sealing here alone is still prone to leakage of spices. At the same time, since the overall extrusion deformation of the sealing ring in the prior art is small, the sealing ability is low, and some spices will overflow along the gap between the plug-in tube and the circular hole, resulting in the problem of ultimately being unable to achieve effective sealing. In addition, during the use of the material tank, it is necessary to frequently pull out and insert the connector, which causes frequent friction between the sealing ring and the material tank, causing the sealing ring to wear faster, and also causing the sealing ring to shift and leave the original sealing position, which in turn causes the sealing ring to be excessively deformed or lost, ultimately shortening the service life of the sealing ring. Utility Model Content

[0004] The utility model aims to provide a cigarette can sealing ring, which solves the problem that the sealing ring in the prior art has a small deformation amount and cannot perform effective sealing.

[0005] To achieve this purpose, the utility model adopts the following technical solution: the utility model provides a cigarette can sealing ring, the cigarette can sealing ring is sleeved on the plug-in tube of the plug-in component, the cigarette can sealing ring comprises a sealing part and a sleeve part, the sleeve part is sleeved on the outside of the plug-in tube, the sleeve part is inserted into the circular hole on the can, the sealing part is arranged on the periphery of the sleeve part, and the plug-in cover on the upper side of the plug-in tube presses the sealing part on the outer wall of the can;

[0006] At least two groups of first protrusions are formed on the upper side of the sealing portion, and at least two groups of second protrusions are formed on the lower side of the sealing portion. The first protrusions abut against the plug-in cover, and the second protrusions abut against the material tank. The first protrusions and the second protrusions are distributed circumferentially around the plug-in tube.

[0007] Preferably, the second protrusions include four groups, and the second protrusions are distributed radially along the circular hole.

[0008] Preferably, the first protrusions include four groups, the first protrusions are distributed radially along the circular hole, and the first protrusions and the second protrusions are symmetrically distributed along the sealing portion.

[0009] Preferably, a reinforcement ring is provided in the sealing portion, and the reinforcement rings are distributed at equal intervals along the radial direction of the cigarette can sealing ring.

[0010] Preferably, three layers of reinforcement rings are provided in the sealing portion.

[0011] Preferably, the axial length of the sleeve portion is greater than the thickness of the material tank, the sleeve portion is rectangular, and the edge of the sleeve portion is chamfered.

[0012] Preferably, a wear-resistant layer is further provided on the outer side of the sealing portion, and the hardness of the wear-resistant layer is greater than that of the sealing portion.

[0013] Preferably, the cigarette can sealing ring is made of tetrafluoroethylene monomer.

[0014] Preferably, a supporting portion is further formed on the lower side of the sealing portion, the supporting portion is higher than the second protruding portion, a limiting portion is formed on the supporting portion, a limiting hole is formed on the outer wall, and the limiting portion is inserted into the limiting hole.

[0015] Preferably, the axial length of the sleeve portion is greater than the length of the plug-in tube, and a wire mesh is installed at one end of the sleeve portion away from the plug-in cover, and the wire mesh is embedded in the side wall of the sleeve portion.

[0016] Beneficial effect: by adding a sealing part to the outside of the sleeve part, the sealing area of ​​the cigarette can is increased and the sealing ability is improved. When the sleeve part is added between the circular hole and the plug-in tube, the sealing part is also added between the plug-in cover and the outer wall, so that the cigarette can sealing ring of the utility model can achieve sealing at the above two positions, increase the sealing area, and improve the sealing ability. When the plug-in cover is connected to the sealing part, the plug-in cover and the sealing part squeeze the first protrusion, causing the first protrusion to deform and expand to both sides, thereby expanding the contact area between the first protrusion and the sealing cover, and improving the sealing ability of the cigarette can sealing ring. Similarly, when the second protrusion is squeezed, the contact area between the second protrusion and the outer wall is also expanded, which can also improve the sealing ability of the cigarette can sealing ring.

[0022] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only the parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0023] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" 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 a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. 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.

[0025] In the description of this embodiment, the terms "upper", "lower", "right", etc., are based on the directions or positions shown in the drawings, and are only for the convenience of description and simplified 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 a limitation of the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0026] Under the existing technology, the connector is divided into two parts, namely, a plug-in cover and a plug-in tube. The plug-in cover abuts against the outer wall, the plug-in tube is plugged into the circular hole of the material tank, and the sealing ring is sleeved on the plug-in tube. When the plug-in tube is inserted into the circular hole, the outer side of the sealing ring abuts against the inner wall of the circular hole. The sealing through the above position has a low sealing ability and is prone to leakage. The cross-section of the sealing ring under the existing technology is rectangular, and the cross-sectional area is too small, which will result in a small deformation of the sealing ring, and the sealing ability of the sealing ring is low. In addition, the sealing ring is prone to wear after long-term use, resulting in failure of the sealing ring and loss of sealing ability.

[0027] In order to solve the above problems, Figures 1 to 4 As shown, the utility model provides a cigarette can sealing ring, which is annular and has an L-shaped cross section. The cigarette can sealing ring is sleeved on the plug-in tube of the plug-in component. The cigarette can sealing ring comprises a sealing portion 1 and a sleeve portion 2. The sleeve portion 2 is sleeved on the outside of the plug-in tube, and the sleeve portion 2 is inserted into the circular hole on the can. The sealing portion 1 is arranged on the periphery of the sleeve portion 2, and the plug-in cover on the upper side of the plug-in tube presses the sealing portion 1 onto the outer wall of the can. At least two groups of first protrusions 11 are formed on the upper side of the sealing portion 1, and at least two groups of second protrusions 12 are formed on the lower side of the sealing portion 1. The first protrusion 11 abuts against the plug-in cover, and the second protrusion 12 abuts against the can. The first protrusion 11 and the second protrusion 12 are distributed circumferentially around the plug-in tube.

[0028] The utility model adds a sealing portion 1 to the outer side of the original sleeve portion 2, increases the sealing position, and improves the sealing ability of the sealing ring. When the plug-in cover is connected to the outer wall of the material tank, the first protrusion 11 will be squeezed, so that the first protrusion 11 will be deformed along the radial direction, so that the sealing area between the first protrusion 11 and the plug-in cover becomes larger, and the sealing ability is improved. A gap is formed between adjacent first protrusions 11 to avoid mutual squeezing between the first protrusions 11 and the occurrence of a loose buckle of the plug-in cover; similarly, through the squeezing between the sealing portion 1 and the outer wall of the material tank, the second protrusion 12 will be deformed, so that the sealing area between the cigarette material tank sealing ring and the material tank is increased, and the sealing ability is increased. The deformation of the first protrusion 11 and the second protrusion 12 can improve the sealing ability of the cigarette material tank sealing ring and avoid leakage of the material tank.

[0029] The second protrusions 12 of the utility model include four groups, and the second protrusions 12 are distributed along the radial direction of the circular hole. Since four groups of annular second protrusions 12 are provided, four layers of sealing areas are formed between the material tank and the sealing part 1, thereby preventing the leakage of the spices inside the material tank and improving the sealing ability. At the same time, the gaps between the second protrusions 12 also leave space for the deformation of the second protrusions 12, preventing the second protrusions 12 from squeezing each other, so that the plug-in can be plugged into the target position while being sealed with the cigarette material tank sealing ring.

[0030] Similarly, the first raised parts 11 include four groups, so four layers of sealing areas are formed between the plug-in cover and the sealing part 1, thereby preventing the leakage of the spices inside the material tank and improving the sealing ability. At the same time, the gaps between the first raised parts 11 also leave space for the deformation of the first raised parts 11, preventing the first raised parts 11 from squeezing each other, so that the plug-in can be sealed with the cigarette material tank sealing ring and plugged into the target position. Even if one of the first raised parts 11 or the second raised parts 12 leaks, the remaining first raised parts 11 and the second raised parts 12 can still continue to seal the material tank, reducing the fault tolerance and improving reliability.

[0031] In addition, the first raised portion 11 and the second raised portion 12 are symmetrically distributed along the sealing portion 1. Since the first raised portion 11 and the second raised portion 12 are squeezed by the upper and lower sides of the sealing portion 1 at the same time, the first raised portion 11 and the second raised portion 12 abut against and inhibit each other's deformation in a direction perpendicular to the sealing portion 1, thereby increasing the deformation of the first raised portion 11 and the second raised portion 12 in the radial direction of the sealing ring, increasing the contact area between the first raised portion 11 and the second raised portion 12 and the plug-in cover and the material tank, and improving the sealing ability.

[0032] A reinforcing ring 13 is provided in the sealing part 1, and the reinforcing rings 13 are evenly spaced along the radial direction of the cigarette can sealing ring. By providing the reinforcing ring 13, the strength of the sealing part 1 can be improved, the cigarette can sealing ring can be prevented from being broken and deformed, and its service life can be extended. During the process of inserting or removing the connector, the reinforcing ring 13 can suppress the deformation of the cigarette can sealing ring, so that it can always maintain its original shape, extend its service life, and avoid fatigue deformation.

[0033] The cross section of the reinforcement ring 13 is rectangular, and three layers of reinforcement rings 13 are inserted into the sealing portion 1, which can further enhance the sealing ability of the cigarette can sealing ring.

[0034] A support portion 14 is also formed on the lower side of the sealing portion 1. The support portion 14 is higher than the second protruding portion 12. A limiting portion 15 is formed on the support portion 14, and a limiting hole is formed on the outer wall, so that the limiting portion 15 can be inserted into the limiting hole. When installing the cigarette canister sealing ring, the limiting portion 15 is inserted into the limiting hole, which can make the cigarette canister sealing ring and the canister more firmly connected, avoid deformation of the cigarette canister sealing ring, and extend the service life.

[0035] The axial length of the sleeve part 2 is greater than the thickness of the material tank. The sleeve part 2 is rectangular. The edge of the sleeve part 2 is provided with a chamfer 21 to facilitate installation by workers. The sleeve part 2 of the utility model is longer than the length of the sealing ring in the prior art. On the one hand, the strength of the sleeve part 2 can be increased. On the other hand, the sealing area between the sleeve part 2 and the inner wall of the circular hole can be increased, and the sealing area between the sleeve part 2 and the plug-in tube can also be increased to improve the sealing ability.

[0036] The outer side of the sealing part 1 of the utility model is also provided with a wear-resistant layer 3, the hardness of the wear-resistant layer 3 is greater than that of the sealing part 1, and a flange is formed at the edge of the plug-in tube, the flange is perpendicular to the plug-in cover, and the flange is in contact with the wear-resistant layer 3. In the process of repeatedly inserting and removing the plug-in part, the wear degree of the flange and the cigarette material can sealing ring is reduced, and the length and service life of the sleeve part 2 are extended.

[0037] The axial length of the sleeve part 2 is greater than the length of the plug-in tube. A wire mesh is installed at the end of the sleeve part 2 away from the plug-in cover. The wire mesh is embedded in the side wall of the sleeve part 2. The wire mesh can improve the structural strength of the sleeve part 2, avoid excessive deformation, and extend the service life of the cigarette can sealing ring.

[0038] The material of the cigarette can sealing ring is a polymer compound formed by the polymerization reaction of tetrafluoroethylene monomer. It has an ultra-wide temperature resistance range and can still maintain excellent physical stability in an environment of -60°C to 260°C. At the same time, its outstanding acid and alkali resistance, corrosion resistance and organic solvent resistance greatly reduce the possibility of material damage, thereby significantly improving the durability and sealing reliability of the cigarette can sealing ring. The cigarette can sealing ring has excellent high temperature resistance, low temperature resistance, acid and alkali corrosion resistance and organic solvent resistance, so that it can maintain stable sealing performance in various complex environments. Before installing the above-mentioned sealing ring, it is necessary to wipe off the grease on the can.

[0039] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here.
