Description

Technical Field

[0001] The invention relates to the technical field of smoking articles, in particular to a cigarette cartridge and an electronic cigarette that prevent a cigarette holder from overheating. Background Art

[0002] Electronic cigarettes are a new type of electronic product that looks similar to ordinary cigarettes and has the same taste as ordinary cigarettes. Since electronic cigarettes heat the oil through an atomizer to produce smoke that can be inhaled, compared with traditional cigarettes, electronic cigarettes do not burn, do not produce a variety of harmful chemicals after combustion, and do not cause harm to others and pollution to the environment due to "second-hand smoke", so electronic cigarettes are healthier and more environmentally friendly than traditional cigarettes.

[0003] Since the electronic cigarettes in the prior art use heating to atomize the e-liquid, the temperature of the cigarette cartridge rises rapidly during the atomization process and is quickly transferred to the mouthpiece, causing the temperature of the mouthpiece in direct contact with the user to be too high, which not only affects the user's smoking experience, but also easily causes mouth burns to the user. Although there are measures to cool the atomization device in the prior art, the prior art sets the cooling device at a downstream position of the smoke circulation. Since the downstream position is close to the position where the user contacts the mouthpiece, if the temperature is not cooled in time, it is easy to cause the part of the mouthpiece that contacts the user to become hot. In addition, while the cooling device of the prior art cools and cools down at one end, heat is generated at the other end, and heat accumulation is prone to occur, which seriously affects the cooling effect of the cigarette cartridge.

[0025] Embodiment 1:

[0026] like Figure 1 and Figure 2 As shown, the present embodiment provides a cigarette cartridge that prevents the cigarette holder 20 from overheating. The cigarette cartridge of the present embodiment is used in conjunction with a cigarette rod with a power supply. The power supply provides electrical energy to the atomization device of the cigarette cartridge, and the atomization device converts the electrical energy into heat to atomize the cigarette oil stored in the oil tank 10 of the cigarette cartridge. When the user inhales in the cigarette holder 20, a negative pressure is formed at the cigarette oil outlet of the atomization device of the cigarette cartridge. Under the action of the negative pressure, air enters the cigarette cartridge from the air inlet of the cigarette cartridge, and brings the atomized cigarette oil to the smoking port 21 of the cigarette holder 20 along the internal air flow channel of the cigarette cartridge for the convenience of the user to inhale. The temperature of the cigarette oil is relatively high during the atomization process, and the heat is rapidly transferred from the bottom 12 of the oil tank 10 to the cigarette holder 20, causing the temperature of the cigarette holder 20 to rise rapidly. The present embodiment cools the corresponding cigarette cartridge through a corresponding cooling system.

[0027] like Figure 2As shown, the cigarette cartridge for preventing the cigarette holder 20 from overheating in this embodiment includes an oil tank 10 for storing cigarette oil, a cooling system for cooling the cigarette cartridge and a cigarette holder 20 mounted on the oil tank 10, wherein a smoking port 21 is formed on the cigarette holder 20, and the cooling system includes a refrigeration device, a cooling conduction structure and a heat dissipation structure. The refrigeration device includes a cold end that generates cold and a hot end that generates heat, the cooling conduction structure is used to conduct the cold generated by the cold end of the refrigeration device to the oil tank 10, and the heat dissipation structure is used to dissipate the heat from the hot end of the refrigeration device, the cooling conduction structure is located on the side of the refrigeration device facing the smoking port 21, and the heat dissipation structure is located on the side of the refrigeration device opposite to the smoking port 21.

[0028] In this embodiment, the oil tank 10 is used as the oil storage component of the cigarette cartridge, and a receiving chamber for receiving the cigarette oil is formed in the oil tank 10. In specific implementation, part of the material in the oil tank 10 can be removed to form the receiving chamber, or the oil tank 10 with the receiving chamber can be manufactured by an integrated molding method. The opening of the receiving chamber is opened on the side facing away from the inhalation port 21, and the cigarette oil is injected into the receiving chamber from the aforementioned opening when the cigarette cartridge is produced.

[0029] In this embodiment, the mouthpiece 20 as a part of the shell of the cigarette cartridge is sleeved on the outside of the oil tank 10. When using, the user holds the mouthpiece 20 in his mouth and inhales, and the atomized smoke enters the user's mouth through the inhalation port 21 on the mouthpiece 20.

[0030] The refrigeration device preferably uses a semiconductor refrigeration sheet 40, which is composed of many N-type and P-type semiconductors arranged mutually. The refrigeration effect of the semiconductor refrigeration sheet 40 can be controlled by controlling the input current. The semiconductor refrigeration sheet 40 does not require any refrigerant when refrigerating, can work continuously, has no pollution source and no rotating parts, will not produce a rotation effect, has no sliding parts and is a solid piece. There is no vibration and noise when working, and the service life is long. In other embodiments, the refrigeration device can also use other devices such as loop heat pipes and heat pumps. This type of refrigeration device includes a cold end that generates cold and a hot end that generates heat, that is, one end cools and the other end generates heat. The semiconductor refrigeration sheet 40 is usually in the form of a sheet, so one side of the refrigeration sheet 40 is installed facing the oil tank 10, and the other side is installed away from the oil tank 10. In this embodiment, a cold conduction structure is added to the refrigeration end of the refrigeration device, so that the cold generated by the refrigeration device is quickly transferred to the oil tank 10, so that the oil tank 10 is quickly cooled. At the same time, this embodiment adds a heat dissipation structure to the end of the refrigeration device that generates heat, and quickly dissipates the heat from the end of the refrigeration device that generates heat, so as to avoid heat accumulation at the hot end of the refrigeration device, causing the temperature of the refrigeration device to be too high, and affecting the cooling effect of the refrigeration device on the cigarette cartridge. In this embodiment, the cold end and the cooling structure of the refrigeration device face the oil tank 10, and the cold amount of the refrigeration device can be quickly transferred to the oil tank 10, so that the temperature of the smoke can be reduced at a place far away from the cigarette holder 20, avoiding the situation where the temperature of the cigarette holder 20 is too high due to untimely cooling. At the same time, the hot end and the heat dissipation structure of the refrigeration device face the side away from the smoking port 21, and the heat of the cigarette cartridge is quickly transferred to the side away from the smoking port 21, so that the cooling effect and cooling speed of the cooling system are significantly increased.

[0031] Since the atomization device is close to the bottom 12 of the oil tank 10, in order to quickly cool down the cigarette cartridge before the heat generated by atomization is conducted to the mouthpiece 20, the present embodiment makes the cooling structure abut against the surrounding wall 11 of the oil tank 10 and the bottom 12 of the oil tank 10 to conduct the cold to the surrounding wall 11 and the bottom 12 of the oil tank 10, thereby centrally cooling the cigarette cartridge in the heat-generated area, and effectively cooling the cigarette cartridge before the heat is conducted to the mouthpiece 20.

[0032] like Figure 3 and Figure 4As shown, the cooling structure includes a cooling plate, which includes a first sub-plate 41 having one end in close contact with the cold end of the refrigeration device and a second sub-plate 42 extending from the first sub-plate 41 toward the oil tank 10 to a position at a first preset distance from the bottom 12 of the oil tank 10, and the second sub-plate 42 abuts against the peripheral wall 11 of the oil tank 10. The end of the oil tank 10 close to the refrigeration device is the bottom 12 of the oil tank 10, and the surface connected to the outer edge of the bottom 12 of the oil tank 10 is the peripheral wall 11 of the oil tank 10. The cold energy generated by the refrigeration device is first conducted to the first sub-plate 41, and then conducted from the first sub-plate 41 to the second sub-plate 42. The second sub-plate 42 abuts against the peripheral wall 11 of the oil tank 10, because the second sub-plate 42 extends from the first sub-plate 41 toward the oil tank 10 to a position at a first preset distance from the bottom 12 of the oil tank 10. Therefore, the second sub-piece 42 conducts the cold energy of the refrigeration device to the height range from the bottom 12 of the oil tank 10 to the first preset distance from the bottom 12 of the oil tank 10, and uses the cold energy generated by the refrigeration device within this height range to quickly and centrally cool the oil tank 10, so that the heat will not be conducted to the area outside the height range, so as to avoid burns to the user. Since the heat generated by atomization is initially gathered at the bottom 12 of the oil tank 10, the first preset distance of this embodiment can be determined according to the size of the cigarette bomb and the position where the heat is initially gathered during atomization. In this way, the second sub-piece 42 can conduct the cold energy to the area where the heat is gathered at the first time the heat is generated, and quickly cool down the area in a targeted manner, so as to achieve cooling of the cigarette holder 20 before the heat is conducted to the vicinity of the cigarette holder 20.

[0033] like Figure 3 As shown, in order to improve the cooling effect, the present embodiment further adds a first heat dissipation fin group 51, one end of the first heat dissipation fin group 51 abuts against one end of the second sub-piece 42 opposite to the peripheral wall 11 of the oil tank 10, and the other end extends in a direction opposite to the second sub-piece 42. The first heat dissipation fin group 51 can transfer the heat of the oil tank 10 to the periphery of the oil tank 10 through the second sub-piece 42 for heat exchange, so as to enhance the heat dissipation effect on the oil tank 10.

[0034] In order to further improve the cooling effect and cooling speed, the smoke bomb in this embodiment also includes a second heat dissipation fin group 52 which is alternately arranged with the second sub-piece 42 along the circumferential direction of the peripheral wall 11 of the oil tank 10, and one end of the second heat dissipation fin group 52 is abutted against the peripheral wall 11 of the oil tank 10, and the other end extends in a direction opposite to the peripheral wall 11 of the oil tank 10.

[0035] In this embodiment, the second sub-sheets 42 and the second heat dissipation fin group 52 are arranged alternately in the circumferential direction of the oil tank 10, so that the peripheral wall 11 of the oil tank 10 forms an alternately arranged cooling zone and heat dissipation zone. In this way, the limited cooling capacity generated by the refrigeration device in a short time can be concentrated in the area of ​​the peripheral wall 11 with faster heat conduction, so as to prevent the heat from being conducted in the direction of the cigarette holder 20 at the first time, and at the same time, the effective area of ​​the peripheral wall 11 of the oil tank 10 is fully utilized, and the second heat dissipation fin group 52 is used to dissipate heat from the oil tank 10. Since there are cooling zones on both sides of the heat dissipation zone, the speed of heat dissipation in the heat dissipation zone can be accelerated, and the temperature difference between the area where the peripheral wall 11 of the oil tank 10 contacts the second sub-sheet 42 and other areas of the peripheral wall 11 can be reduced, so that the influence of the temperature difference in different areas on the peripheral wall 11 of the oil tank 10 is avoided while achieving rapid cooling. In this embodiment, the heat of the oil tank 10 is controlled within a range below the first preset distance by the coordinated use of the second sub-sheet 42 and the second heat dissipation fin.

[0036] The smoke bomb also includes a first cold conduction plate 54 abutting against the bottom 12 of the oil tank 10 and a guide plate group 53 extending from the first cold conduction plate 54 toward the direction of the first cold conduction plate 54 opposite to the bottom 12 of the oil tank 10, and the end of the first sub-piece 41 opposite to the refrigeration device abuts against the guide plate group 53, and the first cold conduction plate 54 conducts the cold energy of the first sub-piece 41 to the bottom 12 of the oil tank 10 through the guide plate group 53.

[0037] In this embodiment, the cold energy of the first sub-sheet 41 is transferred to the first cold conduction plate 54 through the guide plate group 53, and the cold energy is transferred to the bottom 12 of the oil tank 10 through the first cold conduction plate 54, so as to quickly cool down the bottom 12 of the oil tank 10 where the heat is concentrated. The guide plate group 53 includes a first sub-guide plate group 53 and a second sub-guide plate group 53 which are perpendicular to each other. Each sub-guide plate group 53 is composed of a plurality of guide plates which are spaced a certain distance apart from each other. The first sub-guide plate group 53 and the second sub-guide plate group 53 are perpendicular to each other, so that the cold energy of the first sub-sheet 41 can be fully and evenly transferred to each area of ​​the bottom 12 of the oil tank 10, so as to cool down the bottom 12 of the oil tank 10, so as to reduce the temperature difference of the bottom 12 of the oil tank 10 while rapidly cooling down. In this embodiment, the first sub-sheet 41, the guide plate group 53, the second sub-sheet 42, the first heat dissipation fins and the second heat dissipation fins are used in combination to simultaneously cool and dissipate heat from the bottom 12 and the surrounding wall 11 of the oil tank 10, cool the area where the heat is initially concentrated during atomization, and clamp the conduction of heat within a range away from the mouthpiece 20.

[0038] like Figure 3 and Figure 5As shown, specifically, this embodiment also includes a first shell 50, the first heat dissipation fin group 51 is formed by the inner wall of the first shell 50 extending toward the oil tank 10 to a position abutting against the second sub-piece 42, the second heat dissipation fin group 52 is formed by the inner wall of the first shell 50 extending toward the oil tank 10 to a position abutting against the peripheral wall 11 of the oil tank 10, the first cooling plate 54 is rectangular, one pair of opposite ends of the first cooling plate 54 is connected to the inner wall of the first shell, and a gap 60 is formed between the other pair of opposite ends and the inner wall of the shell for the second sub-piece 42 to pass through, the second sub-piece 42 of the cooling plate passes through the gap 60 so that the first sub-piece 41 of the cooling plate abuts against the guide plate group 53, and the second sub-piece 42 abuts against the peripheral wall 11 of the oil tank 10, and the first heat dissipation fin, the second heat dissipation fin, the guide plate group 53 and the shell are an integrally formed structure.

[0039] The first heat dissipation fin group 51 and the second heat dissipation fin group 52 are both composed of a plurality of fins spaced a certain distance from each other. In this embodiment, a plurality of fin groups are arranged at different positions, so the shape of the cooling structure is relatively complex and the manufacturing difficulty is high. In this regard, in this embodiment, the first heat dissipation fin group 51, the second heat dissipation fin group 52 and the guide plate group 53 are separated from the cooling fins, and a first shell 50 is added, so that the first heat dissipation fin group 51, the second heat dissipation fin group 52 and the first cooling plate 54 are formed by extending from the inner wall of the first shell 50 toward the oil tank 10, so that the first heat dissipation fin group 51, the second heat dissipation fin group 52 and the first cooling plate 54 can be manufactured separately from the cooling fins to reduce the manufacturing difficulty of the first heat dissipation fin group 51, the second heat dissipation fin group 53 and other complex structures, and at the same time, the shell is used to increase the heat exchange area and enhance the heat exchange effect. In addition, in this embodiment, a gap 60 is formed between the cooling plate and the inner wall of the first shell 50 to allow the second sub-sheet 42 to pass through. The cooling plate manufactured separately can be assembled with the first shell 50, the first heat dissipating fin group 51 and the second heat dissipating fin group 52, the first cooling plate 54 and the guide plate group 53 to form a complete cooling and heat dissipation system at the bottom 12 and the surrounding wall 11 of the oil tank 10.

[0040] This embodiment also includes an atomizing device for atomizing the e-liquid. In this embodiment, one end of the accommodating chamber of the oil tank 10 is in communication with the atomizing device. The atomizing device includes an atomizing core and a coating layer coated on the outer wall of the atomizing core. In this embodiment, the atomizing core is preferably a ceramic atomizing core with good high temperature resistance. A heating component is provided in the atomizing core, and the heating component generates heat for atomizing the e-liquid after the atomizing core is powered on.

[0041] Example 2

[0042] like Figure 6As shown, this embodiment further optimizes the heat dissipation structure based on Embodiment 1. In this embodiment, the heat dissipation structure includes a heat dissipation substrate 71 abutting against the hot end of the refrigeration device and a plurality of heat dissipation bars 71 extending from the substrate to the side of the substrate opposite to the hot end. Adjacent heat dissipation bars 71 are spaced apart by a second preset distance to form a channel for airflow between the heat dissipation bars 71.

[0043] The heat at the hot end of the refrigeration device is first transferred to the heat dissipation substrate 71, and then dispersedly transferred from the heat dissipation substrate 71 to each heat dissipation bar 71. The heat dissipation bar 71 transfers the heat at the hot end of the refrigeration device in a direction away from the smoking port 21. Since adjacent heat dissipation bars 71 are spaced by a second preset distance, the heat dissipation bars 71 can fully exchange heat with the surrounding environment during the heat transfer process to quickly reduce the temperature of the hot end of the refrigeration device, thereby ensuring the refrigeration effect of the cold end of the refrigeration device.

[0044] In order to further improve the heat dissipation effect of the refrigeration device, the present embodiment further includes a fan 73 for driving airflow to flow through the heat dissipation bar 71, and the fan 73 is located on the side of the heat dissipation bar 71 opposite to the refrigeration device. When the refrigeration device is working, the fan 73 is started to make the air near the heat dissipation bar 71 flow quickly and pass through the heat dissipation bar 71, thereby accelerating the heat exchange between the heat dissipation bar 71 and the outside world, thereby improving the heat dissipation effect.
