Referring to FIGS. 1 to 3 , an embodiment of the present disclosure provides a smoking device 100, including a main body 10. The main body 10 includes a slot 11, a smoke storage chamber 121, and an inhalation channel 13 that are communicated with each other. The slot 11 is configured for the insertion of a cigarette 200. The smoke storage chamber 121 is configured to store second-hand smoke generated by burning a burning end of the cigarette 200. The smoke generated by the cigarette 200 can enter the smoker's mouth through the inhalation channel 13. Generally, the cigarette 200 includes a cigarette filter end and a cigarette butt end (the burning end) that are connected to each other, and the cigarette filter end of the cigarette 200 is inserted into the slot 11.
Further, the smoking device 100 has a puff state in which the cigarette 200 inserted into the slot 11 is being puffed, and a non-puff state in which the cigarette 200 inserted into the slot 11 is not being puffed. In the puff state, the inhalation channel 13 is opened, and pressures in the smoke storage chamber 121 and the slot 11 are greater than a pressure in the inhalation channel 13. In this case, the gas in the smoke storage chamber 121 and the smoke generated by the cigarette 200 inserted into the slot 11 all flow into the inhalation channel 13, and then enter a user's mouth through the inhalation channel 13 for the user to smoke. In the non-puff state, the inhalation channel 13 is closed, in other words, the inhalation channel 13 is no longer opened, and the smoke can no longer flow to an outside through the inhalation channel 13. In this case, a pressure in the slot 11 is greater than a pressure in the smoke storage chamber 121. In the non-puff state, since the inhalation channel 13 is closed, and the pressure in the slot 11 is greater than the pressure in the smoke storage chamber 121, the smoke generated by the cigarette 200 inserted into the slot 11 can enter the smoke storage chamber 121 and be stored for the user to take a next puff.
In the above arrangement, when the smoking device 100 is in the non-puff state, the smoke generated by burning the cigarette 200 can enter the smoke storage chamber 121 and be stored. When the smoking device 100 is in the puff state, the second-hand smoke stored in the smoke storage chamber 121 and the smoke generated by burning the cigarette 200 can enter the user's mouth through the inhalation channel 13 for smoking. In this way, on the basis of ensuring that the user can smoke the cigarette 200 normally, the smoking device 100 can also store the second-hand smoke for the user to smoke next time, achieving the purpose of recycling the second-hand smoke, reducing the harm of smoking to people around, and reducing the waste of resources.
In an embodiment, referring to FIGS. 4 and 5 , the main body 10 includes a base body 14, and a mouthpiece 15. The slot 11 and the smoke storage chamber 121 are both arranged in the base body 14. The inhalation channel 13 is arranged in the mouthpiece 15. The main body 10 includes the mouthpiece 15 to facilitate the user to smoke the cigarette through the smoking device 100.
In an embodiment, referring to FIGS. 6 and 7 , the mouthpiece 15 is movably mounted on the base body 14, to switch between a received position and an extended position relative to the base body 14. At the received position, the mouthpiece 15 is received in the base body 14. At the extended position, the mouthpiece 15 extends out of the base body 14. In this way, the base body 14 protects the mouthpiece 15 to ensure the cleanliness of the mouthpiece 15 and avoid damage to the mouthpiece 15.
Specifically, the mouthpiece 15 is rotatably connected to the base body 14. One of the mouthpiece 15 and the base body 14 is provided with a rotating shaft, and the other one of the mouthpiece 15 and the base body 14 is provided with a matching hole. The rotating shaft passes through the matching hole. The mouthpiece 15 is rotatably connected to the base body 14 through the cooperation between the rotating shaft and the matching hole. Specifically, the base body 14 includes a first joint 16 (referring to FIG. 12 ). The inhalation channel 13 is communicated with the slot 11 and the smoke storage chamber 121 respectively through the first joint 16. The rotating shaft or the matching hole is arranged on the first joint 16.
Referring to FIGS. 8 to 10 , the base body 14 defines a transition channel 17. The slot 11, the smoke storage chamber 121 and the inhalation channel 13 are communicated with each other through the transition channel 17. It should be noted here that in other embodiments, the transition channel 17 may be omitted on the base body 14.
The smoking device 100 further includes a first filter member 18. The first filter member 18 is arranged in an end of the transition channel 17 that connects to the slot 11. The first filter member 18 is configured to filter the smoke flowing from the slot 11 to the inhalation channel 13 or the smoke storage chamber 121, so as to filter out harmful substances in the smoke and protect the health of the user. A filter medium filled in the first filter member 18 includes an unsaturated fatty acid, to intercept tar, nicotine, nicotine, etc. in the smoke, making the smoke generated greener and safer. Moreover, using the unsaturated fatty acid as the filter medium can also ensure that the cigarette 200 has an original taste.
It should be understood that in other embodiments, the filter medium filled in the first filter member 18 may also be other types of mediums that can filter smoke tar or improve the smoking experience of the cigarette.
In an embodiment, referring to FIGS. 3 and 9 , the base body 14 defines an inner cavity. The smoking device 100 includes a sliding member 19 and a second valve 110. The sliding member 19 is slidably arranged in the inner cavity, and divides the inner cavity into the smoke storage chamber 121 and an adjustment chamber 122. The second valve 110 is arranged in the adjustment chamber 122, and forms, together with the base body 14, an airflow channel (not shown in the figure) that communicates the adjustment chamber 122 and the outside. In the puff state, the sliding member 19 can slide in the inner cavity to reduce a volume of the smoke storage chamber 121. Referring to FIG. 3 , when the user puffs the smoking device 100, the inhalation channel 13 is opened under the action of a puff force. In this case, the pressure in the smoke storage chamber 121 is greater than the pressure in the inhalation channel 13, so the gas can enter the inhalation channel 13 from the smoke storage chamber 121. In this case, the airflow flows from the airflow channel to the adjustment chamber 122, and the sliding member 19 slides in the smoke storage chamber 121 to reduce the volume of the smoke storage chamber 121. Referring to FIG. 11 , in the non-puff state, the inhalation channel 13 is closed, and the sliding member 19 can slide in the inner cavity to increase the volume of the smoke storage chamber 121. The airflow in the adjustment chamber 122 can flow to the outside through the airflow channel. As the volume of the smoke storage chamber 121 increases, the pressure decreases accordingly, so that the pressure in the slot 11 is greater than the pressure in the smoke storage chamber 121. As a result, the smoke in the slot 11 can flow to the smoke storage chamber 121 and be stored. Specifically, in the non-puff state, the sliding member 19 slides in the inner cavity under its own gravity, to increase the volume of the smoke storage chamber 121.
Further, the second valve 110 is movably arranged in the adjustment chamber 122. The smoking device 100 has an adjusting member 120. The adjusting member 120 is mounted on the base body 14, and configured to adjust a position of the second valve 110 relative to the base body 14, to adjust a flow area of the airflow channel. In this way, in the non-puff state, by adjusting the size of the flow area of the airflow channel through the adjusting member 120, the descending speed of the sliding member 19 under the action of the gravity can be controlled, so that more second-hand smoke can be sucked into the smoke storage chamber 121.
In an embodiment, the base body 14 defines a second air hole 141 (referring to FIG. 2 ). The airflow channel communicates with the outside through the second air hole 141.
Referring to FIG. 4 , the base body 14 includes a body portion 142 and a tube body 143. The slot 11 is provided on the body portion 142. The mouthpiece 15 is connected to the body portion 142. The tube body 143 and the body portion 142 jointly form the inner cavity. Both the adjusting member 120 and the second valve 110 are arranged on the tube body 143. This arrangement facilitates the arrangement of the inner cavity and the assembly of various components.
Further, referring to FIGS. 5 and 12 , the tube body 143 includes a cylindrical portion 1431 and a bottom cover 1432. The cylindrical portion 1431, the bottom cover 1432, and the body portion 142 are jointly defined to form the inner cavity. The sliding member 19 is arranged inside the cylindrical portion 1431 and can slide along an axis direction of the cylindrical portion 1431. The adjusting member 120 and the second valve 110 are both arranged on the bottom cover 1432.
Referring to FIG. 3 , the second valve 110 is an umbrella-shaped valve, including an umbrella-shaped portion 1101 and an insertion portion 1102 that are connected to each other. The insertion portion 1102 passes through the bottom cover 1432, and the umbrella-shaped portion 1101 is arranged in the adjustment chamber 122. The second air hole 141 is defined in the bottom cover 1432. The adjusting member 120 is an adjusting bolt. The adjusting member 120 passes through the bottom cover 1432, and collides with the umbrella-shaped portion 1101 of the second valve 110. An airflow channel is formed between the umbrella-shaped portion 1101 and the bottom cover 1432. When the flow area of the airflow channel needs to be adjusted, only the adjusting bolt needs to be screwed to change the position of the umbrella-shaped portion 1101 relative to the bottom cover 1432.
In other embodiments, a balloon may be provided in the inner cavity. An air inlet of the balloon is communicated with the airflow channel. In the puff state, the gas in the smoke storage chamber 121 is sucked out under the action of the puff force, and the balloon is inflated to change the volume of the smoke storage chamber 121. In the non-puff state, the inhalation channel 13 is closed, and the airflow in the balloon slowly flows to the outside through the airflow channel, so the balloon gradually shrinks and the smoke storage chamber 121 slowly becomes larger. In this case, a pressure difference is generated between the slot and the smoke storage chamber, causing a suction force to be generated in the smoke storage chamber 121, so that the second-hand smoke generated by the cigarette 200 is sucked into the smoke storage chamber 121.
In an embodiment, referring to FIG. 12 , a first valve 130 is arranged in the inhalation channel 13. Specifically, the mouthpiece 15 includes a connection portion 151 and an inhalation portion 152 that are detachably connected. The connection portion 151 and the inhalation portion 152 jointly form the inhalation channel 13. The mouthpiece 15 is designed to include two detachable parts to facilitate the mounting of the first valve 130. Furthermore, the smoking device 100 further includes a fixed cover 160. The connection portion 151 is fixedly connected to the base body 14 through the fixed cover 160.
In the puff state, the first valve 130 allows the inhalation channel 13 to be opened. In the non-puff state, the first valve 130 closes the inhalation channel 13. Specifically, a second joint 140 is arranged in the inhalation channel 13, and a first air hole 1401 (referring to FIG. 3 ) is defined in the second joint 140. The second valve 110 opens or closes the first air hole 1401, to open or close the inhalation channel 13. Specifically, the first valve 130 is also an umbrella-shaped valve.
Further, a second filter member 150 is arranged in the inhalation channel 13, and configured to filter the smoke entering the inhalation channel 13. In a specific implementation, the second filter member 150 is a filter cotton. In another specific implementation, the filter medium filled in the second filter member 150 is an unsaturated fatty acid, which further intercepts tar, nicotine, nicotine, etc. in the smoke filtered by the first filter member 18, making the generated smoke healthier.
It should be understood that in other embodiments, the filter medium filled in the second filter member 150 may also be other types of mediums that can filter smoke tar or improve the smoking experience of the cigarette.
In an embodiment, referring to FIGS. 1 and 3 , the smoking device 100 further includes a combustion control mechanism 20. The combustion control mechanism 20 includes a housing 21 and a combustion control tube 22. The housing 21 is detachably connected to the body portion 142, and the combustion control tube 22 is slidably mounted on the housing 21. The cigarette inserted into the slot 11 can be inserted into the combustion control tube 22, and the combustion control tube 22 can slide relative to the cigarette 200. In this way, when using the smoking device 100 to smoke the cigarette 200, the combustion control mechanism 20 can be removed from the body portion 142, the cigarette 200 is inserted into the slot 11, and then the combustion control mechanism 20 is mounted on the body portion 142. In this case, the combustion control tube 22 is sleeved on the cigarette 200. Alternatively, the cigarette 200 is first inserted into the combustion control tube 22, and then the combustion control mechanism 20 is mounted on the body portion 142. In this case, the cigarette 200 is inserted into the slot 11.
In the above arrangement, when using the smoking device 100 to smoke the cigarette 200, the combustion control tube 22 is sleeved on the cigarette 200, and the cigarette 200 supports the combustion control tube 22. After the cigarette 200 located in the combustion control tube 22 is burned, the burning end will turn into soot, resulting in insufficient support for the combustion control tube 22. Therefore, the combustion control tube 22 slides downward relative to the housing 21 under the action of gravity and stops at a position where the cigarette 200 can sufficiently support the combustion control tube 22. Since the cigarette 200 is located in the combustion control tube 22, there is a matching gap between the combustion control tube 22 and the cigarette 200 (the matching gap is generally within the range of 0.15 mm to 0.25 mm).
The combustion control tube can control the amount of air, thereby controlling the burning rate of the cigarette to achieve the effect of controlling the burning of the cigarette, avoiding the waste of cigarettes caused by burning the cigarette too fast, and avoiding harming the health of people around due to excessive second-hand smoke naturally generated by the cigarette.
Further, referring to FIG. 6 , when the combustion control mechanism 20 is mounted on the base body 14, the two form a rectangular parallelepiped structure that is easy to hold. The mouthpiece 15 is arranged on a side of the base body 14 away from the combustion control mechanism 20. Moreover, the mouthpiece 15 is a rod-shaped structure with the inhalation portion 152. The base body 14 defines a receiving groove, and the mouthpiece 15 can be received in the receiving groove or extended from the receiving groove. Referring to FIGS. 12 and 13 , the housing 21 includes an inner housing 212 and an outer housing 211 that is sleeved on the inner housing 211. The combustion control tube 22 is arranged in the inner housing 212 and slidably connected to the inner housing 212. The outer housing 211 is made of a heat-insulating material to prevent the heat generated by the cigarette 200 from being transmitted through the outer housing 21 and scalding the user.
In another embodiment, referring to FIG. 4 , the base body 14 may also be configured as a columnar structure that is easy to hold. The combustion control mechanism 20 is arranged on an upper part of the base body 14. When using the smoking device 100, the user can directly hold the base body 14, to avoid contact with the combustion control mechanism 20. In this case, the housing 21 of the combustion control mechanism 20 can also exclude the outer housing 211 and only include the inner housing 212, and the material of the inner housing 212 is not limited.
In an embodiment, referring to FIG. 6 , a cutting member 23 is arranged at an end of the combustion control tube 22 away from the slot 11. When the combustion control tube 22 moves downward under the action of gravity, the cutting member 23 is driven to move downward to cut the soot. The shape of the cutting member 23 is not limited as long as it can achieve the purpose of cutting the soot.
Further, referring to FIG. 13 , the cutting member 23 includes two cutting portions 231 arranged oppositely in a radial direction of the combustion control tube 22. The two cutting portions 231 can cut the soot from both sides of the radial direction, respectively, ensuring the cutting effect.
In some embodiments, the combustion control mechanism 20 includes a sleeve tube 24. The sleeve tube 24 is sleeved on the combustion control tube 22. The combustion control tube 22 is slidably connected to the housing 21 through the sleeve tube 24. The cutting member 23 is connected to the sleeve tube 24.
Specifically, a distance between the cutting portion 231 and an end surface of the combustion control tube 22 is within the range of 0.5 mm to 6 mm, to control a burning height required for the burning of the cigarette 200, preventing the cigarette 200 from extinguishing due to excessive cutting the soot.
The technical features in the above embodiments may be combined arbitrarily. For concise description, not all possible combinations of the technical features in the above embodiments are described. However, provided that they do not conflict with each other, all combinations of the technical features are to be considered to be within the scope described in this specification.
The above-mentioned embodiments only describe several implementations of the present disclosure, and their description is specific and detailed, but should not be understood as a limitation on the patent scope of the present disclosure. It should be noted that, for a person of ordinary skill in the art may further make variations and improvements without departing from the conception of the present disclosure, and these all fall within the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure should be subject to the appended claims.
