Description

Technical Field

[0001] This utility model relates to the field of electronic atomization technology, and in particular to an electronic cigarette with indirect oil supply. Background Technology

[0002] Currently, existing electronic cigarettes have only one independent oil chamber for storing e-liquid, and the air tube is located entirely within this independent oil chamber. The oil inlet on the air tube directly corresponds to the independent oil chamber and the oil-absorbing heating element inside the air tube. When e-liquid is injected into the oil chamber by squeezing the e-liquid bottle, the air pressure and oil pressure inside the oil chamber increase, impacting the air tube. This causes the e-liquid in the oil chamber to leak through the oil inlet and through the oil-absorbing heating element from the air tube's vapor passage. Furthermore, the oil-absorbing heating element directly absorbs e-liquid from the oil chamber through the oil inlet, which can lead to oversaturation of the heating element. This results in excessive e-liquid adhering to the heating wire of the heating element, accelerating the corrosion of the heating wire and affecting the lifespan of the heating element. Utility Model Content

[0003] The purpose of this invention is to provide an indirect e-cigarette, which solves the problems of existing e-cigarettes where, when e-cigarettes are filled by squeezing the e-liquid bottle, the oil and air pressures impact the e-liquid inlet at the lower end of the air tube, causing e-liquid to spray out and leak from the air tube, and where the heating element directly absorbing the e-liquid in the e-liquid chamber accelerates the corrosion of the heating wire.

[0005] In one embodiment, a flue gas channel is formed inside the air pipe, the oil-absorbing heating element is located inside the flue gas channel, and the atomizing body is also provided with a smoke exhaust channel that corresponds to and communicates with the flue gas channel.

[0006] In one embodiment, the oil reservoir is made of polyester fiber, polyurethane, or polyacrylonitrile.

[0007] In one embodiment, the atomizing body includes an oil tank and an oil sealing element. The oil sealing element is disposed inside the oil tank, and the outer wall of the oil sealing element abuts against the inner wall of the oil tank. The internal space of the oil tank above the oil sealing element forms a first oil cavity, and the oil sealing element serves as the bottom wall of the first oil cavity. The oil guiding channel passes through the oil sealing element.

[0009] In one embodiment, the atomizing body further includes an oil plug, and the outer wall of the oil tank has an oil injection hole that corresponds to and communicates with the first oil cavity. The oil plug is detachably inserted into the oil injection hole.

[0010] In one embodiment, the main unit includes a main body shell, the upper end of which is necked to form a connector, the top end of which is recessed to form a second oil cavity, the lower end of which is sleeved on the outer peripheral wall of the connector, the top end of which abuts against the bottom end of which is an oil sealing element, which covers the second oil cavity, the lower end of which is an air pipe extending into the second oil cavity, the oil storage element being wrapped around the lower end of which corresponds to the oil inlet, and the oil guiding channel corresponding to and communicating with the first oil cavity and the second oil cavity.

[0011] In one embodiment, the inner wall of the main shell is provided with a through hole corresponding to and communicating with the second oil cavity.

Thus, when e-liquid is injected into the e-liquid chamber by squeezing the e-liquid bottle, the generated oil pressure and air pressure will not impact the e-liquid inlet at the lower end of the air tube, causing e-liquid to spray out from the smoke channel of the air tube and cause oil leakage. The e-liquid heating element will also not directly absorb too much e-liquid in the e-liquid chamber, causing too much e-liquid to adhere to the heating wire, which will accelerate corrosion.

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.

[0023] It should be noted that the specification of this utility model 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 of the utility model described above, the various technical features of the utility model in the following embodiments and examples, and the various technical features of the utility model 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.

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.

[0024] In this utility model, the terms "upper", "lower", "side", "top", "bottom", "inner", and "outer" are based on the orientation or positional relationship shown in the accompanying drawings and are only for the purpose of describing and understanding the technology of this utility model. They are not intended to limit the device or component to a specific orientation or to be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this utility model.

[0025] like Figure 1-5As shown, this utility model provides an indirect oil-supply electronic cigarette, including a main unit 13 and an atomizing body 12 electrically connected to the main unit 13. The atomizing body 12 has an independent first oil chamber 104 and an air tube 4. The atomizing body 12 is provided with an oil injection hole 101 for injecting oil into the first oil chamber 104. The main unit 13 is provided with a second oil chamber 802 located below the first oil chamber 104. The upper end of the air tube 4 is located in the first oil chamber 104, and the lower end of the air tube 4 is located in the second oil chamber 802. The bottom wall of the first oil chamber 104 is provided with an oil guiding channel 301 for guiding e-liquid into the second oil chamber 802. The second oil chamber 802 is provided with an oil storage component 6. The lower end of the air tube 4 is provided with an oil inlet hole 402. The air tube 4 is provided with an oil-absorbing heating element 5 for sealing the oil inlet hole 402. The main unit 13 is also provided with a power supply component 1301 for supplying power to the oil-absorbing heating element 5. It should be noted that the e-liquid can be first injected into the first oil chamber 104, then introduced into the second oil chamber 802 through the oil guide channel 301 and absorbed by the oil storage component 6. Finally, it is introduced into the oil absorption and heating component 5 through the oil inlet 402 at the lower end of the air pipe 4 through the oil storage component 6 for heating and atomization. Thus, when the e-liquid is injected into the oil chamber by squeezing the e-liquid bottle, the oil pressure and air pressure generated will not impact the oil inlet 402 at the lower end of the air pipe 4, causing the e-liquid to spray out from the smoke channel 401 of the air pipe 4 and cause oil leakage. The oil absorption and heating component 5 will also not directly absorb too much e-liquid in the oil chamber, causing too much e-liquid to adhere to the heating wire 501, which would accelerate corrosion.

[0026] In some embodiments, a smoke passage 401 is formed inside the air tube 4, the oil-absorbing heating element 5 is located inside the smoke passage 401, and the atomizing body 12 is also provided with a smoke exhaust passage 103 corresponding to and communicating with the smoke passage 401. The smoke passage 401 is used to allow airflow and to contain the smoke generated by the oil-absorbing heating element 5 heating the e-liquid. After the airflow enters the smoke passage 401, the smoke can be discharged from the smoke exhaust passage 103 with the airflow for the user to inhale.

The oil sealing element 3 is made of silicone material, which is soft, easy to assemble, has a large deformation coefficient, and provides good sealing effect. The oil sealing element 3 seals the first oil cavity 104 by abutting against the inner wall of the oil tank 1 with its outer wall. The oil guiding channel 301 is integrally formed with the oil sealing element 3.

The through channel 302 and the sealing element 3 are also integrally formed. The upper end of the air pipe 4 is inserted into the first oil cavity 104 through the through channel 302 to isolate the e-liquid in the first oil cavity 104. The mouthpiece 102 is used to hold the mouth in the mouth to smoke. The connecting pipe 105 is used to connect the upper end of the air pipe 4 and simultaneously conduct the smoke exhaust channel 103 and the smoke passage 401, so that when the mouthpiece 102 is inhaled, the smoke can enter the user's mouth.

[0030] In some embodiments, the atomizing body 12 further includes an oil plug 2. The outer wall of the oil tank 1 has an oil filling hole 101 that corresponds to and communicates with the first oil chamber 104. The oil plug 2 is detachably inserted into the oil filling hole 101. After e-liquid is injected into the first oil chamber 104 through the oil filling hole 101, the oil plug 2 can seal the oil filling hole 101 to prevent e-liquid from flowing out.

The connector 801 is used to connect the oil tank 1. The connector 801 and the second oil cavity 802 are integrally formed with the main body shell 8 by in-mold injection molding. The oil tank 1 is connected to the upper end of the main body shell 8 by the lower end being sleeved on the outer peripheral wall of the connector 801. The top end of the connector 801 abuts against the bottom end of the oil sealing component 3 to seal the second oil cavity 802. The oil storage component 6 is wrapped around the lower end of the air pipe 4 to facilitate the entry of e-liquid into the oil absorption heating component 5 from the oil inlet 402.

[0032] In some embodiments, the inner wall of the main body shell 8 has a through hole 803 corresponding to and communicating with the second oil cavity 802. A silicone pad 7 for sealing the through hole 803 is laid at the bottom of the second oil cavity 802. A groove 701 is formed at the top of the silicone pad 7, and the bottom end of the air pipe 4 is inserted into the groove 701. A guide hole 702 communicating with the smoke passage 401 inside the air pipe 4 is formed at the bottom of the groove 701. When the bottom end of the air pipe 4 is inserted into the groove 701, the silicone pad 7 can seal the bottom end of the air pipe 4 to prevent e-liquid from entering the second oil cavity 802 and then leaking into the smoke passage 401.

The battery cell 9 supplies power to the power board 10 to activate its electronic control function. The power board 10 supplies power to the heating wire 501 to generate heat. The oil-absorbing cotton 502 absorbs the e-liquid entering through the oil inlet 402, and the heating wire 501 heats the e-liquid absorbed within the oil-absorbing cotton 502 to produce smoke.

[0034] In some embodiments, the main unit 13 further includes a base 11, which is disposed in the bottom opening of the main body shell 8.
