Description

Technical Field

[0001] This utility model relates to the field of electronic cigarette technology, and in particular to a cartridge and an electronic cigarette using the same. Background Technology

[0002] Currently, existing e-cigarettes design their heating cores to allow airflow to carry away the vapor during inhalation. However, during cartridge assembly, the heating core is subjected to pressure from fingers while being installed into the vapor channel, and pressure differences within the vapor channel during air transport after cartridge assembly. Both of these situations can cause the heating core to deform and indent, leading to short circuits or failure to absorb e-liquid, resulting in dry burning. Furthermore, after e-cigarette assembly, a vacuum tightness test is performed. Since the vapor channel is connected to the outside through the exhaust port and air inlet, and the e-liquid reservoir is connected to the vapor channel through the e-liquid inlet, during vacuum suction, e-liquid in the reservoir will be carried by the airflow through the e-liquid inlet into the heating core, then flow through the heating core into the vapor channel, and finally out of the cartridge through the exhaust port and air inlet, causing leakage and contamination. Utility Model Content

[0003] The purpose of this invention is to provide a cartridge and an electronic cigarette using the same. By designing an air-sealing and pressure-preventing component in the smoke channel to reinforce the heating element, and simultaneously sealing the air inlet and outlet, this invention solves the problems in existing electronic cigarettes where the heating element deforms under pressure and pressure difference in the smoke channel, leading to short circuits or failure to absorb e-liquid, resulting in dry burning. It also addresses the issue that during vacuuming, the smoke channel allows air to pass through, causing e-liquid in the oil storage chamber to be drawn into the smoke channel and then flow out of the cartridge, resulting in oil leakage and contamination.

[0006] In one embodiment, the sealing element is made of silicone, rubber, or latex, and the pressure-resistant element is tubular and made of stainless steel or ceramic.

[0007] In one embodiment, the lower end of the sealing component is necked to form a receiving body, and the anti-pressure component is connected to the sealing component by being sleeved on the receiving body at its upper end. The upper end of the sealing component can be pulled out of the heating core by pulling it outside the cartridge body, and then pulled away from the cartridge body through the smoke channel and the exhaust port.

[0008] In one embodiment, the cartridge body also has an oil guide gap corresponding to the smoke channel and the oil storage cavity. The oil guide gap is provided with oil storage cotton and an oil guide hole for guiding the e-liquid in the oil storage cavity into the oil storage cotton.

[0009] In one embodiment, the cartridge body includes an oil reservoir and an oil separator. The oil separator is disposed within the oil reservoir, and the space between the outer wall of the oil separator and the inner wall of the oil reservoir forms the oil storage cavity. A smoke pipe is disposed within the oil separator, forming the smoke channel. The space between the outer wall of the smoke pipe and the inner wall of the oil separator serves as the oil guiding gap. An oil guiding hole is disposed on the outer wall of the oil separator, corresponding to the oil storage cotton. The wall of the smoke pipe serves as the channel wall of the smoke channel. An oil inlet is disposed on the wall of the smoke pipe, corresponding to the oil storage cotton and the heating element.

[0010] In one embodiment, the cartridge body also includes an oil sealing component, which is disposed in the top opening of the oil tank to seal the oil storage cavity. The bottom end of the oil sealing component is provided with a connector, the upper end of the oil separating pipe is sleeved on the connector, the exhaust port extends from the top end of the oil sealing component to the bottom end of the connector, and the upper end of the smoke pipe is inserted into the exhaust port so that the exhaust port corresponds to and communicates with the smoke channel.

[0011] In one embodiment, the cartridge body also includes a sealing element, the bottom end of the oil tank has a through channel corresponding to the oil storage cavity, the sealing element is disposed in the through channel, the lower end of the oil separator is inserted into the sealing element, and the bottom end of the sealing element has an air inlet corresponding to and communicating with the smoke channel.

[0012] A second aspect of this utility model provides an electronic cigarette, including a shell and a cartridge as described above.

[0023] The following detailed description of the embodiments of this utility model, in conjunction with the accompanying drawings, will provide a thorough understanding of how this utility model uses technical means to solve technical problems and achieve technical effects, enabling its implementation. It should be noted that, provided there is no conflict, the various embodiments and features within them can be combined with each other, and all resulting technical solutions are within the protection scope of this utility model.

[0024] It should be noted that the specification of this application contains a large number of technical features distributed across various technical solutions. Listing all possible combinations of technical features (i.e., technical solutions) would make the specification excessively lengthy. To avoid this problem, the various technical features disclosed in the above-described utility model content, the various technical features disclosed in the following embodiments and examples, and the various technical features disclosed in the accompanying drawings can be freely combined to form various new technical solutions (all of which are considered to have been described in this specification), unless such a combination of technical features is technically infeasible. For example, one example discloses feature A+B+C, and another example discloses feature A+B+D+E. Features C and D are equivalent technical means that serve the same function, and technically only one needs to be used; they cannot be used simultaneously. Feature E can technically be combined with feature C. Therefore, the solution A+B+C+D should not be considered as described because it is technically infeasible, while the solution A+B+C+E should be considered as described.

[0025] In this utility model, the terms "upper", "lower", "top", "bottom", "inner", "outer", etc., are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing and understanding the technology of this utility model, and are not intended to limit the device or component to have a specific orientation or to be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0026] like Figure 1-4As shown, this utility model provides a tobacco cartridge, including a cartridge body 10. The cartridge body 10 has a corresponding smoke channel 401 and an oil storage cavity 601 for storing e-liquid. The smoke channel 401 is provided with a gas sealing and anti-pressure component 1001 and a heating core 5 for heating the e-liquid in the oil storage cavity 601. The cartridge body 10 has an air inlet 701 and a smoke outlet 102 that are respectively corresponding to and communicate with the two ends of the smoke channel 401. The gas sealing and anti-pressure component 1001 is detachably inserted into the heating core 5 and blocks the air inlet 701 and the smoke outlet 102. It should be noted that by designing an air-sealing and pressure-preventing component 1001 within the smoke channel 401 to reinforce the heating core 5, and simultaneously sealing the air inlet 701 and the exhaust outlet 102, the problems of existing electronic cigarettes where the heating core 5 deforms under pressure and pressure difference within the smoke channel 401, leading to short circuits or failure to absorb e-liquid and dry burning, and the problem of e-liquid in the oil storage chamber 601 being drawn into the smoke channel 401 and then flowing out of the cartridge during vacuuming, causing oil leakage and pollution, are solved.

[0027] In some embodiments, the gas sealing and pressure-prevention assembly 1001 includes a gas sealing element 8 and a pressure-prevention element 9 connected to each other. The pressure-prevention element 9 is detachably inserted into the heating core 5, and its lower end extends from the air inlet 701 and is exposed outside the cartridge body 10, blocking the air inlet 701. The upper end of the gas sealing element 8 extends from the exhaust port 102 and is exposed outside the cartridge body 10, blocking the exhaust port 102. It should be noted that the gas sealing and pressure-prevention assembly 1001 blocks the air inlet 701 by blocking the lower end of the pressure-prevention element 9 and the exhaust port 102 by blocking the upper end of the gas sealing element 8. During vacuuming, because the smoke passage 401 is not permeable, the gas in the oil storage chamber 601 will not enter the smoke passage 401 with the e-liquid, and will then flow out from the air inlet 701 and the exhaust port 102 respectively, causing oil leakage.

[0028] In some embodiments, the sealing element 8 is made of silicone, rubber, or latex, and the pressure-resistant element 9 is tubular and made of stainless steel or ceramic. In this embodiment, the sealing element 8 is preferably made of silicone, which is environmentally friendly, does not shed lint, has a large deformation coefficient, does not produce harmful substances, and does not generate impurities in the smoke passage 401, effectively sealing the exhaust port 102. In this embodiment, the pressure-resistant element 9 is made of stainless steel, which is hard and will not break or bend, can be easily inserted into the heating core 5, and will not be corroded by the e-liquid inside the heating core 5. Together with the silicone sealing element 7, it effectively seals the air inlet 701.

[0029] In some embodiments, the lower end of the sealing element 8 is necked to form a receiving body 801. The anti-pressure element 9 is connected to the sealing element 8 by being sleeved on the receiving body 801 at its upper end. The upper end of the sealing element 8 can be pulled out of the heating core 5 by pulling it outside the cartridge body 10, and then pulled away from the cartridge body 10 through the smoke channel 401 and the exhaust port 102. The receiving body 801 is used to connect the anti-pressure element 9 and the sealing element 8 together. The receiving body 801 and the sealing element 8 are integrally molded by liquid silicone in-mold injection molding. When the electronic cigarette is in use, the upper end of the sealing element 8 can be pulled out of the cartridge body 10 by pulling it, thereby opening the air inlet 701 and the exhaust port 102 and connecting them to the smoke channel 401.

[0030] In some embodiments, the cartridge body 10 also has an oil guide gap 202 corresponding to the smoke channel 401 and the oil storage chamber 601. The oil guide gap 202 is provided with an oil storage cotton 3 and an oil guide hole 201 for guiding the e-liquid in the oil storage chamber 601 into the oil storage cotton 3. An oil inlet hole 402 is provided on the channel wall corresponding to the smoke channel 401 so that the e-liquid in the oil storage cotton 3 can enter the heating core 5. The oil guiding gap 202 is used to guide oil and accommodate the oil storage cotton 3. The e-liquid in the oil storage cavity 601 can enter the oil guiding gap 202 through the oil guiding hole 201 and be absorbed by the oil storage cotton 3. The e-liquid in the oil storage cotton 3 can enter the heating core 5 through the oil inlet hole 402 and be heated to produce smoke. It should be noted that by placing the oil storage cotton 3 in the oil guiding gap 202 to absorb the e-liquid in the oil storage cavity 601, compared with existing electronic cigarettes, the volume of the oil storage cotton 3 can be reduced by two-thirds by completely filling the oil storage cavity 601, which can save the manufacturing cost of the oil storage cotton 3. Moreover, with a smaller volume, the oil storage cotton 3 will not have too much e-liquid adhering inside and unable to enter the heating core 5, thereby improving the e-liquid utilization rate.

[0031] In some embodiments, the cartridge body 10 includes an oil tank 6 and an oil separator 2. The oil separator 2 is disposed inside the oil tank 6. The space between the outer wall of the oil separator 2 and the inner wall of the oil tank 6 forms an oil storage cavity 601. A smoke pipe 4 is disposed inside the oil separator 2. A smoke channel 401 is formed inside the smoke pipe 4. The space between the outer wall of the smoke pipe 4 and the inner wall of the oil separator 2 serves as an oil guiding gap 202. An oil guiding hole 201 is disposed on the outer wall of the oil separator 2, corresponding to the oil storage cotton 3. The pipe wall of the smoke pipe 4 serves as the channel wall of the smoke channel 401. An oil inlet hole 402 is disposed on the pipe wall of the smoke pipe 4, corresponding to the oil storage cotton 3 and the heating core 5. The oil separator 2 is used to isolate the e-liquid in the oil storage chamber 601 and resist the oil pressure of the e-liquid in the oil storage chamber 601, preventing the e-liquid from being excessively absorbed by the oil storage cotton 3, thereby indirectly causing the heating core 5 to excessively absorb e-liquid. Under the action of gravity, the bottom of the heating core 5 drips oil. Both the oil separator 2 and the smoke pipe 4 are made of stainless steel, which is resistant to e-liquid corrosion and the high temperature generated by the heating core 5.

[0032] In some embodiments, the cartridge body 10 further includes an oil-sealing component 1, which is disposed within the top opening of the oil tank 6 to seal the oil storage cavity 601. A connector 101 is provided at the bottom end of the oil-sealing component 1, and the upper end of the oil-separating tube 2 is sleeved on the connector 101. An exhaust port 102 extends from the top of the oil-sealing component 1 to the bottom of the connector 101. The upper end of the smoke pipe 4 is inserted into the exhaust port 102, so that the exhaust port 102 corresponds to and communicates with the smoke channel 401. The oil-sealing component 1 and the sealing component 7 are made of silicone, which is soft, easy to assemble, has a large deformation coefficient, and provides a good sealing effect for the oil storage cavity 601. The connector 101 is used to connect and position the upper end of the oil-separating tube 2, and the exhaust port 102 is used to connect and position the upper end of the smoke pipe 4, thereby ensuring that the exhaust port 102 corresponds to and communicates with the smoke channel 401 for smoke exhaust.

[0033] In some embodiments, the cartridge body 10 further includes a sealing element 7. The bottom end of the oil tank 6 has a through channel 602 corresponding to the oil storage cavity 601. The sealing element 7 is disposed within the through channel 602. The lower end of the oil separator 2 is inserted into the sealing element 7. The bottom end of the sealing element 7 has an air inlet 701 corresponding to and communicating with the smoke channel 401. The sealing element 7 is also made of silicone, which is soft, easy to assemble, has a large deformation coefficient, and provides good sealing of the oil storage cavity 601. The through channel 602 is used to accommodate the sealing element 7. After the lower end of the anti-pressure member 9 extends from the air inlet 701, the sealing element 7 adheres to the outer wall of the anti-pressure member 9, sealing the air inlet 701. The air inlet 701 is used to introduce air into the smoke channel 401, driving the smoke flow.

[0034] like Figure 5 and Figure 6 As shown, a second aspect of this utility model provides an electronic cigarette, including a shell 11 and a cartridge as described above. The cartridge body 10 is disposed inside the shell 11. The shell 11 is also provided with a power supply assembly 17 for supplying power to the cartridge body 10. The top of the shell 11 is provided with a mouthpiece 1101. The mouthpiece 1101 has a smoking channel 1102 that corresponds to and communicates with the exhaust port 102. The upper end of the sealing member 8 of the sealing and anti-pressure assembly 1001 extends out of the smoking channel 1102 and is exposed outside the mouthpiece 1101. The outer shell 11 is used to house the cartridge body 10 and the power supply component 17. When the electronic cigarette is in use, the sealing element 8 is pulled upward from the smoking channel 1102 of the mouthpiece 1101. The sealing element 8 and the anti-pressure element 9 can be pulled out sequentially through the exhaust port 102 and the smoking channel 1102. The mouthpiece 1101 is used to hold the cigarette in the mouth to smoke. After the power supply component 17 supplies power to the cartridge body 10, it can make the heating core 5 heat up and heat the e-liquid to produce smoke.

[0035] In some embodiments, the system further includes a base 12 and an air guide 13. The base 12 is located at the bottom of the housing 11, and the air guide 13 is located inside the base 12. The top of the air guide 13 has an air guide groove 1301 that corresponds to and communicates with the air inlet 701. A liquid suction member 16 is provided inside the air guide groove 1301. The bottom of the base 12 has an air inlet channel 1201 that communicates with the air guide groove 1301. The air inlet channel 1201 communicates with the air inlet 701 through the air guide groove 1301. The power supply assembly 17 includes a battery cell 14 and a power board 15. The battery cell 14 is electrically connected to the power board 15, and the power board 15 is electrically connected to the heating element 5. The base 12 is used to seal the bottom of the outer shell 11. The air guide groove 1301 is used to guide air and collect the condensate formed by the liquefaction of smoke in the smoke channel 401. The oil absorber is made of cotton material to absorb the condensate in the air guide groove 1301. The battery 14 is used to supply power to the power board 15 to start its electronic control function. The power board 15 is used to supply power to the heating core 5 to make it heat up. When smoking with the mouthpiece 1101, the external airflow can enter the air guide groove 1301 from the air inlet 1201, and then enter the smoke channel 401 from the air inlet 701 through the air guide groove 1301. Then, the smoke generated by the heating core 5 heating the e-liquid will enter the user's mouth through the exhaust port 102 and the smoking channel 1102 and be inhaled.

The oil separating tube 2 is installed inside the oil tank 6, and the space between the outer wall of the oil separating tube 2 and the inner wall of the oil tank 6 forms an oil storage cavity 601 for storing e-liquid. The oil separating tube 2 isolates the e-liquid within the oil storage cavity 601 and resists the oil pressure of the e-liquid within the oil storage cavity 601. A smoke pipe 4 is provided inside the oil separating tube 2, forming a smoke channel 401 for airflow and exhaust. The smoke generator and heating element 5 are located in the smoke channel 401 to heat the e-liquid. An oil-guiding gap 202 is formed between the outer wall of the smoke pipe 4 and the inner wall of the oil separator 2 to guide oil and accommodate the oil-retaining cotton 3. The oil-retaining cotton 3 is installed in the oil-guiding gap 202 to absorb the e-liquid. The outer wall of the oil separator 2 has corresponding oil-guiding holes 201 to allow the e-liquid in the oil storage chamber 601 to enter the oil-guiding gap 202 and be absorbed by the oil-retaining cotton 3.

The top of the oil sealing component 1 has a smoke exhaust port 102 that extends to the bottom of the connector 101 for positioning and connecting the flue gas pipe 4. The upper end of the flue gas pipe 4 is inserted into the smoke exhaust port 102 so that the smoke exhaust port 102 corresponds to and communicates with the flue gas channel 401 for exhausting smoke. The bottom of the oil tank 6 has a through channel 602 corresponding to the oil storage cavity 601 for accommodating the sealing component 7. The sealing component 7 is installed in the through channel 602 for sealing the oil storage cavity 601. The lower end of the oil separator 2 is inserted into the sealing component 7 for connection and positioning. The bottom of the sealing component 7 has an air inlet 701 corresponding to and communicating with the flue gas channel 401. The gas sealing element 8 is used to introduce air into the smoke channel 401 to drive the smoke flow. The lower end of the sealing element 8 is constricted to form a receiving body 801 to connect the anti-pressure element 9 and the sealing element 8 together. The upper end of the anti-pressure element 9 is sleeved on the receiving body 801 and connected to the lower end of the sealing element 8. The anti-pressure element 9 and the sealing element 8 are inserted into the smoke channel 401 from the exhaust port 102 in sequence. The anti-pressure element 9 passes through the heating core 5, and the lower end of the anti-pressure element 9 extends out from the air inlet 701 and is exposed outside the sealing element 7. The lower end of the anti-pressure element 9 blocks the air inlet 701. The upper end of the sealing element 8 extends out from the exhaust port 102 and is exposed outside the sealing oil element 1. The upper end of the sealing element 8 blocks the exhaust port 102. All the components are combined together to form the main body 10 of the cigarette cartridge.

[0038] The cartridge body 10, battery cell 14, and power board 15 are installed inside the outer casing 11. The battery cell 14 is electrically connected to the power board 15 to supply power to the power board 15 and enable its electronic control function.
