Description

Technical Field

[0001] The present invention relates to the technical field of smoking devices, and in particular to a cigarette adapter and a smoking device comprising the cigarette adapter. Background Art

[0002] The burning of cigarettes during smoking produces a large amount of ash and smoke, which can cause indoor environmental pollution. Therefore, the smoking device products on the market work on the principle of placing the burning part of the cigarette inside the smoking device to avoid pollution.

[0003] Existing smoking devices adapt to cigarettes of different sizes by replacing rubber heads of different sizes, but only one specification of rubber head is needed at a time. Since the rubber heads of other specifications are relatively scattered, for a portable smoking device, the user needs to carry rubber heads of multiple specifications in order to replace the rubber heads at any time to match cigarettes of different thicknesses, which seriously reduces the user experience.

[0004] In order to adapt to cigarettes of different sizes, the existing smoking devices often need to be set as a non-closed opening at the smoke inlet of the smoking device, which easily causes the ash produced by the burning cigarette to leak out from the opening and cause pollution, especially the ash that has not fallen off attached to the burning end of the cigarette. This part of the ash will be taken out of the smoking device when the cigarette butt is taken out, which will also cause pollution.

[0048] Example 1

[0049] See also Figure 1-Figure 10The embodiment of the present invention discloses a cigarette adapter, comprising a fixed ring mechanism 1, a dynamic ring mechanism 2, a clamping ring 3, a plurality of diaphragm pieces 4 and an elastic mechanism 5; the fixed ring mechanism 1 is provided with a mounting groove 11 and a limiting groove 12 surrounding the inner wall of the fixed ring mechanism 1, and a smoke inlet 13 is provided in the mounting groove 11; the dynamic ring mechanism 2 is movably arranged in the mounting groove 11, and a rotating handle 21 is extended from the dynamic ring mechanism 2; the clamping ring 3 is arranged in the limiting groove 12 to support the dynamic ring mechanism 2; the diaphragm piece 4 is extended with a spring piece 41 The fence piece 4 is clamped between the mounting groove 11 and the dynamic ring mechanism 2, and the dynamic ring mechanism 2 drives the fence piece 4 to rotate in the mounting groove 11 to open or close the smoke inlet 13; the elastic mechanism 5 includes a first fixed portion 51 arranged at the bottom of the fixed ring mechanism 1, a second fixed portion 52 arranged at the bottom of the dynamic ring mechanism 2, and an elastic member 53, and the two ends of the elastic member 53 are respectively sleeved on the first fixed portion 51 and the second fixed portion 52 to limit the dynamic ring mechanism 2 from driving the fence piece 4 to open the smoke inlet 13.

[0050] Specifically, the fixed ring mechanism 1 is a finger ring structure, and its annular bottom extends a support surface inwardly toward the center of the circle to form a mounting groove 11 inside, and a hollow smoke inlet 13 is provided in the mounting groove 11 to provide an opening for the cigarette column to pass through the cigarette adapter. The moving ring mechanism 2 is a circular ring structure and the outer diameter of the moving ring mechanism 2 is smaller than the inner diameter of the fixed ring mechanism 1, so that the moving ring mechanism 2 can be movably placed in the mounting groove 11 of the fixed ring mechanism 1 and the bottom of the mounting groove 11 supports the first surface of the moving ring mechanism 2. When the moving ring mechanism 2 rotates relative to the fixed ring mechanism 1, the centers of the two mechanisms are the same center, and a rotating handle 21 is extended on the ring wall of the rotating mechanism 2 so that the user can push the rotating handle 21 to rotate the moving ring mechanism 2 relative to the fixed ring mechanism 1.

[0051] Furthermore, the fixed ring mechanism 1 is a finger-shaped structure, and therefore the limiting groove 12 opened on the inner wall of the fixed ring mechanism 1 is an annular groove structure, and the height distance between the annular groove and the bottom of the mounting groove 11 is greater than the thickness of the moving ring mechanism 2. When the first surface of the moving ring mechanism 2 is placed in the mounting groove 11, the second surface of the moving ring mechanism 2 can be supported by the retaining ring 3 arranged in the limiting groove 12, so as to limit the moving ring mechanism 2 in the mounting groove 11 of the fixed ring mechanism 1 without affecting the rotation of the moving ring mechanism 2 relative to the fixed ring mechanism 1.

[0052] Furthermore, the number of the aperture pieces 4 can be adjusted according to actual needs. For example, if the opening of the smoke inlet 13 needs to be further reduced, the number of the aperture pieces 4 can be increased, wherein the first surface of the aperture piece 4 abuts the bottom of the mounting groove 11, and the second surface of the aperture piece 4 abuts the first surface of the moving ring mechanism 2. When the moving ring mechanism 2 is rotated, the transmission aperture piece 4 moves at the smoke inlet 13, and the structure of the multiple aperture pieces 4 can be understood as a structure similar to the aperture piece of a lens.

[0053] As an example, when the smoke inlet 13 needs to be opened, multiple flaps 4 can be moved in the opposite direction of closing the smoke inlet 13 (it can be clockwise or counterclockwise, and the specific moving direction is adjusted according to the setting of the flap 4), and multiple overlapping flaps 4 are moved from the center point of the smoke inlet 13 to the wall of the mounting groove 11 to gradually expand the opening size of the smoke inlet 13 until the opening of the smoke inlet 13 is opened. The user can insert a cigarette column through the smoke inlet 13 after the smoke inlet 13 is opened, and the user can pour out the ashes in the smoker from the opening to clean the smoker.

[0054] As an example, when the smoke inlet 13 needs to be closed, multiple filler pieces 4 can be moved along the circumferential direction of the opening of the smoke inlet 13 (either clockwise or counterclockwise), and the multiple filler pieces 4 overlap in sequence to gradually reduce the size of the opening of the smoke inlet 13 until the opening is closed, thereby preventing ash in the smoker from leaking out of the smoke inlet 13. After the cigarette column passes through the smoke inlet 13, the spring piece 41 provided on the filler piece 4 can clamp the columnar structure so that the smoke inlet 13 of the cigarette adapter can always adapt to cigarettes of different sizes (taking two different cigarette specifications of coarse cigarettes and thin cigarettes as an example, if the user first uses the cigarette adapter to clamp the coarse cigarette and then replaces the thin cigarette, the opening of the filler piece 4 at the smoke inlet 13 can be further contracted by rotating the movable ring mechanism , the spring piece 41 on the filler piece 4 contracts toward the center of the smoke inlet 13 to clamp the thin cigarette, and vice versa), the smoker does not need to replace the cigarette adapter to adapt to different cigarette specifications when using the cigarette adapter, only one cigarette adapter is needed to allow the smoker to adapt to cigarettes of different sizes, dimensions and specifications, and the user can linearly adjust the entrance diameter of the adaptation process, and even cigarettes of unconventional sizes and specifications can also be adapted, and when the cigarette is burned out, when the cigarette is taken out from the smoke inlet 13, the ash attached to the end of the cigarette butt will be scraped off by the spring piece 41 set on the filler piece 4 and retained in the smoker, so as to avoid the ash at the cigarette butt being taken out when the cigarette butt is taken out to cause pollution, and the user does not need to be troubled by repeatedly cleaning the ash, thereby improving the user's smoking experience.

[0055] As a preferred embodiment, the elastic mechanism 5 can pull the second fixing part 52 toward the first fixing part 51 through the elastic potential energy of the elastic member 53, so that the fence piece 4 driven by the dynamic ring mechanism 2 always changes its movement state toward the contracted smoke inlet 13. When the smoking device is not in use, the elastic mechanism 5 can ensure that the smoke inlet 13 of the cigarette adapter is always in a closed state, avoiding the leakage of cigarette ash from the smoke inlet 13 and causing pollution, especially in indoor environments (such as beds, seats and sofas) and in-vehicle environments (such as the main and co-pilot seats), where it is difficult to clean cigarette ash, thereby solving the problem of ash leakage prevention of the smoking device. Furthermore, under the action of the elastic member 53, the spring piece 41 arranged on the fence piece 4 can also obtain a higher clamping force, and can clamp the cigarette column through the spring piece 41 To prevent it from loosening, especially when taking out the cigarette butt, the higher intensity clamping force can completely scrape off the ash remaining on the cigarette butt, avoiding the ash being brought out by the cigarette butt and causing environmental pollution. It is easy for technicians in this field to know that the working principle of the first fixing part 51, the second fixing part 52 and the elastic member 53 in the elastic mechanism 5 is mainly to provide a force for the fixed ring mechanism 1 and the dynamic ring mechanism 2 to always close the smoke inlet 13. In addition to the above structure, it can also be a spring sheet arranged between the fixed ring mechanism 1 and the dynamic ring mechanism 2 to provide the force to close the smoke inlet 13, and it can also be a reset protrusion on the fixed ring mechanism 1 that abuts against the dynamic ring mechanism 2 to provide the force to close the smoke inlet 13. As long as the structure can provide a structure that allows the smoke inlet 13 to always remain closed to the center of the opening, the effect of this embodiment can also be achieved.

[0056] In an optional embodiment, a positioning groove 14 and a positioning protrusion 15 are provided on the outer wall of the fixing ring mechanism 1, and a rubber ring 16 for mounting the cigarette adapter on the smoking device is provided in the positioning groove 14, and the positioning protrusion 15 extends along the outer wall of the fixing ring mechanism 1 to limit the movement of the fixing ring mechanism 1.

[0057] Specifically, the positioning groove 14 is an annular groove surrounding the outer circumferential wall of the fixed ring mechanism 1. The rubber ring 16 arranged in the positioning groove 14 can increase the friction when the cigarette adapter is installed on the smoking device to prevent the cigarette adapter from falling off. The fixed ring mechanism 1 is a finger ring structure. In order to further reduce the situation where the rotating ring mechanism 2 drives the fixed ring mechanism 1 to rotate together, the positioning protrusion 15 extends from the outer wall of the fixed ring mechanism 1. In conjunction with the structure of the smoking device that engages with the positioning protrusion 15 (such as the positioning portion 61), it can not only reduce the rotation of the fixed ring mechanism 1, but also cooperate with the rubber ring 16 to further fix the cigarette adapter on the smoking device. When replacing or removing the cigarette adapter, the positioning protrusion 15 can act as a fulcrum to take the cigarette adapter out of the smoking device.

[0058] In an optional embodiment, the fixed ring mechanism 1 is provided with a pin hole 1A located inside the mounting groove 11, the movable ring mechanism 2 is provided with a pin groove 2A located at the inner ring, and the first end 42 and the second end 43 of the filler piece 4 are provided with a pin protrusion 4A, and the pin protrusion 4A is respectively inserted into the pin hole 1A and the pin groove 2A.

[0059] Specifically, a plurality of pin holes 1A are provided at the bottom of the installation groove 11 near the smoke inlet 13, and the depth of the pin hole 1A only needs to reach a depth that can accommodate the pin protrusion 4A, and the dynamic ring mechanism 2 is an annular structure, and a pin groove 2A with an appropriate depth is provided at the inner ring position of the annular structure, and the depth range of the pin groove 2A can be 50%-90% of the difference between the outer and inner diameters of the dynamic ring mechanism 2, wherein the number of pin holes 1A and pin grooves 2A are the same as the number of the aperture pieces 4, for example, 8 aperture pieces 4 are provided in the cigarette adapter, then at least 8 pin holes 1A are provided in the installation groove 11, and at least 8 pin grooves 2A are provided in the dynamic ring mechanism 2, and the specific number can be set according to business needs.

[0060] In an optional embodiment, the movable ring mechanism 2 drives the fence piece 4 to rotate the pin protrusion 4A on the first end 42 as the center so that the second end 43 moves between the installation groove 11 and the smoke inlet 13;

[0061] The second end portion 43 moves from the inner wall of the installation groove 11 to the smoke inlet 13 to close the smoke inlet 13 , and the second end portion 43 moves from the smoke inlet 13 to the inner wall of the installation groove 11 to open the smoke inlet 13 .

[0062] As an example, taking the depth of the pin groove 2A as 75% of the difference between the outer and inner diameters of the dynamic ring mechanism 2 as an example, the depth of the pin groove 2A determines the stroke of the pin protrusion 4A on the second end 43 of the flap member 4. When the smoke inlet 13 is in a fully open state, the first end 42 and the second end 43 are both close to the inner wall of the fixed ring mechanism 1. After the dynamic ring mechanism 2 is rotated, the pin protrusion 4A on the second end 43 moves from the deepest part of the pin groove 2A to the center point of the smoke inlet 13, and the second end 43 of the dynamic ring mechanism 2 will move toward the center point of the smoke inlet 13 to shrink the opening size of the smoke inlet 13 until the pin is opened. The pin protrusion 4A located in the pin groove 2A moves to the maximum stroke, thereby closing the smoke inlet 13. Conversely, if the smoke inlet 13 needs to be opened, the pin protrusion 4A moves from the opening of the pin groove 2A to the deepest part of the pin groove 2A, and the second end 43 closing the opening of the smoke inlet 13 moves from the smoke inlet 13 to the inner wall of the fixed ring mechanism 1 until it is close to the fixed ring mechanism, thereby opening the smoke inlet 13, wherein the extension directions of the pin protrusion 4A located on the first end 42 and the second end 43 are opposite, and the fence piece 4 is an arc-shaped structure that can be close to the fixed ring mechanism of the finger ring structure, thereby making the overall structure more compact and small.

[0063] In an optional embodiment, the spring piece 41 is located between the first end 42 and the second end 43 and extends into the smoke inlet 13, and a plurality of spring pieces 41 extending from the aperture piece 4 are located in the smoke inlet 13 to form a funnel-shaped structure.

[0064] Specifically, the filler piece 4 is an arc-shaped structure. Before processing, a spring piece 41 is provided between the first end 42 and the second end 43 of the filler piece 4 on one side of the inner circle and extends toward the center of the inner circle. During processing, the spring piece 41 is bent and formed in the direction of insertion of the cigarette column by machining (for example, stamping). When multiple filler pieces 4 shrink and close the opening at the smoke inlet 13, the filler pieces 4 overlap and shrink in sequence, and the spacing between the spring pieces 41 on the filler piece 4 extending into the smoke inlet 13 is reduced. When the spring pieces 41 are pressed against each other, a funnel-shaped structure is formed to clamp the cigarette, and the elastic spring piece 4 will not excessively squeeze the cigarette, nor will it affect the smoke delivery. When facing cigarettes of different specifications and sizes (such as thick cigarettes, medium cigarettes and thin cigarettes), the degree of shrinkage of the filler piece 4 can be adjusted to achieve the purpose of clamping the cigarette. In particular, when the user takes out the cigarette butt after smoking the cigarette, the ash at the end of the cigarette butt will be scraped off by the spring piece 41 with the funnel-shaped structure, so that the ash will always remain in the smoking device, solving the problem of pollution caused by ash.

[0065] In an optional embodiment, the fixed ring mechanism 1 is located on the groove wall of the installation groove 11 and is provided with an opening 111 for extending the rotating handle 21 from the installation groove 11. The setting of the opening 111 can make the structure of the cigarette adapter more compact and small, thereby increasing the adaptability of the cigarette adapter to the smoking device. The smoking device only needs to provide a small space to set the assembly groove to install the cigarette adapter on the smoking device. At the same time, the extended rotating handle 21 can be close to the upper surface of the smoking device to prevent the rotating handle 21 from shaking up and down, so that the rotating handle 21 can always keep moving left and right to control the action of the dynamic ring mechanism 2, thereby increasing the service life of the rotating handle.

[0066] Example 2

[0067] See also Figure 1-Figure 10 The difference between Example 2 of the present invention and Example 1 is that the retaining ring 3 includes an inner ring portion 31 and an outer ring portion 32, the outer ring portion 32 is inserted into the limiting groove 12 to allow the retaining ring to be installed in the fixed ring mechanism 1, and the inner ring portion 31 extends into the installation groove 11 to support the dynamic ring mechanism 2.

[0068] Specifically, after the clamping ring 3 is inserted into the limiting groove 12, another part of the clamping ring 3 extends out of the limiting groove 12 and extends to the smoke inlet 13. The part of the clamping ring 3 extending toward the smoke inlet 13 can support the dynamic ring mechanism 2 installed in the installation groove 11. In order to make the overall structure of the cigarette adapter more compact and small, in this embodiment, the clamping ring 3 can be designed as a structure with multiple outer ring parts 31 and inner ring parts 32 connected in sequence at intervals. In the actual assembly process, the installation of the clamping ring 3 is achieved by inserting the outer ring part 31 of the clamping ring 3 into the limiting groove 12, and then the inner ring part 32 of the clamping ring 3 supports the dynamic ring mechanism 2. Since the inner ring parts 32 are arranged at intervals, gaps are left between adjacent inner ring parts 32 to facilitate the assembly, disassembly and adjustment of the dynamic ring mechanism 2. Similarly, the outer ring parts 31 are also arranged at intervals, and the gaps left between adjacent outer ring parts 31 facilitate the assembly, disassembly and adjustment of the clamping ring 3. The structure of the clamping ring itself is more compact and small, and the gaps left between the inner ring parts 31 and the outer ring parts 32 can provide more activity space in the installation groove.

[0069] Example 3

[0070] See also Figure 1-Figure 10 The second aspect of the present invention discloses a smoking device, comprising a cigarette adapter as disclosed in the first aspect of the present invention, wherein the smoking device 8 has a smoke inlet area provided with an assembly groove 6, and the cigarette adapter 7 is detachably installed in the assembly groove 6.

[0071] In an optional embodiment, a positioning portion 61 adapted to the positioning protrusion 15 is provided on the edge of the assembly groove 6 to prevent the fixed ring mechanism 1 from rotating relative to the movable ring mechanism 2 , and a movable portion 62 is provided in the assembly groove 6 to provide space for the rotating handle 21 .

[0072] Specifically, an assembly groove 6 adapted to the volume of the cigarette adapter can be provided on the smoking device 8, and the cigarette adapter 7 is installed in the assembly groove 6. The positioning protrusion 15 on the cigarette adapter 7 is inserted into the positioning portion 61 to fix the position of the cigarette adapter 7 and prevent the cigarette adapter 7 from loosening and affecting the rotation of the moving ring mechanism 2. It is easy for technicians in this field to know that providing a fixing groove 17 at the bottom of the cigarette adapter 7 and providing a fixing protrusion 63 at the bottom of the assembly groove 6 can also achieve the effect of the positioning protrusion 15 and the positioning portion 61 cooperating with each other to complete the fixing of the cigarette adapter 7, and the positioning protrusion 15 and the positioning portion 61, the fixing groove 17 and the fixing protrusion 63 cooperate with each other to complete the fixing of the cigarette adapter 7, and the cigarette adapter 7 is fixed by the simultaneous cooperation of the positioning protrusion 15 and the positioning portion 61, and the fixing groove 17 and the fixing protrusion 63.

[0073] As an example, the smoke inlet 13 in the cigarette adapter 7 is connected to the flue of the smoking device 8. When the smoking device is not in use, the cigarette adapter 7 closes the smoke inlet 13 to prevent the ash in the smoking device from leaking out. When the smoking device 8 is in use, the rotating handle 21 is turned to open the smoke inlet 13 to insert the cigarette column into the flue, and the fence piece 4 and the spring piece 41 will clamp the cigarette. Preferably, an elastic mechanism 5 can be added to automatically contract the fence piece 4 and the spring piece 41 to clamp the cigarette. When the cigarette is burned out or cannot continue to burn and the cigarette butt needs to be removed, the spring piece 41 will scrape off the remaining ash on the cigarette butt and retain it in the flue to prevent the ash from polluting the external environment. The smoking device equipped with the cigarette adapter can not only clamp cigarettes of various sizes to adapt to different cigarette specifications, but also ensure that there is no ash pollution during the use of the smoking device. The cigarette adapter body has a small and compact structure and is easy to assemble and disassemble. It can be applied to most smoking devices and has a high application value in the field of smoking devices.

[0074] Furthermore, in order to provide sufficient oxygen for the burning of cigarettes, the existing smoking device needs to be provided with gaps or air holes in the smoke inlet area of ​​the smoking device. The smoke from the burning cigarette will emerge from the smoke inlet area to smoke the user's face. In particular, the smoke can easily cause discomfort to the user's eyes, seriously affecting the user experience. After the smoking device is equipped with the cigarette adapter 7, the separately provided smoke inlet 13 can reduce the emission of smoke generated by the burning cigarette, reduce the impact of the smoke generated by the burning cigarette on the user's eyes, and improve the user experience of using the smoking device.

[0075] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
