The present invention relates to the field of electronic heating products. More specifically, the present invention relates to an atomization assembly and an electronic cigarette.
Referring to
At the present, the diameter of the heating wire 104 is 0.08-0.13 mm. The diameter of the heating wire 104 is small, so the contact area with the glass fiber line 103 is small and the temperature for atomizing oil is 220°-300°. In order to increase the volume of the smoke to meet the demands of the users with large vital capacity, the current flowing through the heating wire 104 is increased and the temperature of the heating wire 104 energized is 300°-600°. However, it is easy to burn the oil-absorbing cotton 101 in this way and the lifetime of the electronic cigarette will be affected. Additionally, the volume of the smoke can also be increased by increasing the length of the heating wire 104. However, as the electronic cigarette is used to simulate conventional cigarette, it is more acceptable that the size of the electronic cigarette is comparative to that of the conventional cigarette. Accordingly, the cross sectional areas of the electronic cigarette and the vent tube 102 in the electronic cigarette is limited. The increasable length of the heating wire 104 is limited because of the limited cross sectional area of the vent tube 102, and the increasable volume of the smoke is hence also limited and can't meet the users' demands.
Additionally, the oil-absorbing cotton 101 configured as an oil container and the atomizer are integrally formed, which can't be detached.

The present invention will be further described with reference to the accompanying drawings and embodiments in the following, in the accompanying drawings:
In order to explain the purpose, the technical features, and the effect of the present application more clearly, the specific embodiments of the present application will be described in detail referring to the drawings. Understandably, the specific embodiments described here are only used to explain the present application, but not to limit the present application.
As shown in
Further, a first electrode connecting element 34 electronically connected to the heating wire assembly 31 and a fixed sleeve 33 abutted against the first electrode connecting element 34 are provided in one end of the atomization sleeve 30. The heating wire assembly 31 is received in the fixed sleeve 33, and the liquid delivery element 311 is fixed along an axial direction of the fixed sleeve 33.
In a traditional electronic cigarette, the liquid delivery element 311 is fixed along a radial direction of the fixed sleeve 33. As the radial length of the fixed sleeve 33 is limited, the length of the heating wire 312 twined around the liquid delivery element 311 is hence limited. However, as the axial length of the fixed sleeve 33 is much greater than the radial length of the fixed sleeve 33, the length of the liquid delivery element 311 fixed along the axial direction of the fixed sleeve 33 is unlimited, and the length of the heating wire 312 twined around the liquid delivery element 311 can be set based on actual needs to increase the volume of the smoke to meet the demands of the users with large vital capacity. Furthermore, as the smoke is discharged from the end of the atomizer 3, opposite to the oil container 2, and as the oil container 2 is detachable, the probability that users suck the oil will be greatly reduced and it is convenient to add oil.
In the following, the specific structure of the atomizer 3 of the atomization assembly is described in detail combining with the embodiments shown in
The atomizer 3 is configured to atomize the oil stored the oil container 2. One end of the atomizer 3 is detachably connected to the oil container 2, and the other end of the atomizer 3 is detachably connected to the battery assembly 4.
Referring to
The atomization sleeve 30 is approximately in form of a hollow cylinder, and opens at both ends. The oil container 2 is connected to one end of the atomization sleeve 30, and the battery assembly 4 is connected to the other end of the atomization sleeve 30. An inlet hole (unlabeled) of the atomizer 3 may be defined on the atomization sleeve 30, or may be defined on a surface through which the atomization sleeve 30 abuts against the oil container 2.
The heating wire assembly 31 comprises the liquid delivery element 311 and the heating wire 312 twined around an outer surface of the liquid delivery element 311. The heating wire 312 is configured to atomize the oil in the oil container 2. In the embodiment, the liquid delivery element 311 is received in the fixed sleeve 33 along an axial direction. The liquid delivery element 311 is glass fiber line made of glass fiber material. The liquid delivery element 311 is capable of adsorbing oil and possesses good heat resistance, so it can be better prevented from burning. Preferably, the diameter of the glass fiber line is lmm-2.5 mm. In addition, the liquid delivery element 311 can be made of other material which isn't limited here.
In order to improve the volume of the smoke, make users such enough smoke and improve users' experience, the heating wire 312 is compacted to platy structure or the diameter of the heating wire 312 is increased to increase the contact area between the heating wire 312 and the liquid delivery element 311. For example, the heating wire 312 is made of nichrome wire with the resistance value of 1.5Ω-4.5Ω and the diameter of 0.12 mm-0.17 mm. In addition, the axis of the liquid delivery element 311 is set to be overlapped with or parallel to the axis of the fixed sleeve 33 to achieve the above effects. In order to improve product yield, assemble convenience and make the volume of the smoke as large as possible, in the embodiment, the axis of the liquid delivery element 311 overlaps with the axis of the fixed sleeve 33.
The oil delivery mechanism 32 is mainly configured to deliver the oil in the oil container 2 to the heating wire assembly 31 to be atomized. One end of the oil delivery mechanism 32 is inserted into the oil container 2 to absorb the oil stored in the oil container 2 and deliver the oil absorbed to the heating wire assembly 31 to be atomized.
Referring to
Specifically, the oil latch element 322 and the liquid delivery element 311 are both in form of a solid cylinder and are coaxially arranged. The cross sectional area of the oil latch element 322 is greater than that of the liquid delivery element 311, so that the oil deliver path is in form of a ladder-like structure which can keep the oil latch element 322 at a saturated oil absorption condition and the liquid delivery element 311 at a moderate oil absorption condition. Thus the oil can be obtained from the oil latch element 322 by the liquid delivery element 311 at any time. Therefore, the volume of the smoke can be improved further and the situation that the heating wire assembly 31 runs dry can be avoided. It can also prevent the oil in the oil container 2 from leaking out. The atomizer 3 is ensured to produce smoke with steady volume. In the embodiment, the axis of the liquid delivery element 311 and the axis of the fixed sleeve 33 are overlapped. Of course, the axis of the liquid delivery element 311 and the axis of the fixed sleeve 33 may be parallel to each other or form a certain angle, and it is unlimited there.
In the embodiment, a nonwoven fabric layer 323, a cotton core layer 324 and a composite cotton layer 325 are successively provided in the oil latch element 322. The liquid delivery element 311 abuts against the nonwoven fabric layer 323. Comparing with the oil latch element 322 made of single material, the oil latch element 322 made of various different material with different oil absorption ability has better oil absorption effect and can deliver the oil better to the heating wire 312 of the heating wire assembly 31 to be atomized to increase the volume of the smoke. In additional, as the cotton core layer 324 and the composite cotton layer 325 can absorb large amount of oil, the nonwoven fabric layer 323 is provided on the cotton core layer 324 to buffer the oil and prevent a large amount of oil from flowing into one end of the liquid delivery element 311 to cause oil leakage.
In other embodiments, oil leakage can be avoided further by increasing the amount of the nonwoven fabric layer 323, or by adding at least one nonwoven fabric layer 323 between the cotton core layer 324 and the composite cotton layer 325. Referring to
The fixed sleeve 33 is approximately in form of a cylinder. The fixed sleeve 33 is a glass fiber sleeve made of glass fiber. The glass fiber sleeve is capable of absorbing oil, with excellent heat-resistance, and can avoid being charred better. One end of the fixed sleeve 33 is connected to the first electrode connecting element 34 by a plug connection, and the fixed sleeve 33 is sleeved within one end of the oil conduit 321, opposite to the oil container 2. Furthermore, the heating wire assembly 31 is received in the fixed sleeve 33. The liquid delivery element 311 is provided along the axial direction of the fixed sleeve 33. The two ends of the heating wire 312 twined around the liquid delivery element 311 respectively pass through the fixed sleeve 33 and connect to the first electrode connecting element 34.
Advantageously, in order to make the heating wire 312 atomize oil better and ensure the atomizer 3 to produce stable volume of smoke, the length that the liquid delivery element 311 extends out of the fixed sleeve 33 at the end close to the oil latch element is 1 mm-10 mm, the length between the end of the heating wire 312 that near the oil latch element 322 and the tail end of the fixed sleeve 33 (that is the end of the fixed sleeve 33 that near the oil latch element 322) is 0 mm-5 mm, and the spacing between the end of the liquid delivery element 311 that near the oil latch element 322 and the nonwoven fabric layer 323 is 0 mm-3 mm.
Specifically, in the embodiment, at least two through holes (unlabeled) configured to be extended through by the heating wire 312 are defined on the peripheral wall of the fixed sleeve 33. One end of the heating wire 312 passes through the through holes to electrically connect to a first electrode 341 of the first electrode connecting element 34, the other end of the heating wire 312 passes through the bottom of the fixed sleeve 33 to electrically connect to a second electrode 342 of the first electrode connecting element 34.
Furthermore, airflow can circulate through the through holes defined on the peripheral wall of the fixed sleeve 33. In the embodiment, airflow enters into the fixed sleeve 33 through the inlet hole defined on the atomization sleeve 30 and the through holes, so the airflow circulates without passing through the oil container 2, and it can prevent the oil from leaking and avoid the users sucking the oil.
The first electrode connecting element 34 is located in one end of the atomization sleeve 30, opposite to the oil container 2. The first electrode connecting element 34 is mainly configured to connect to the battery assembly 4 and the heating wire assembly 31 respectively and provide working power for the heating wire assembly 31. In the embodiment, the first electrode connecting element 34 comprises the first electrode 341, the second electrode 342, and a first insulating ring 340 sleeved between the first electrode 341 and the second electrode 342 and configured for electrical insulation.
Specifically, in the embodiment, the first insulating ring 340 comprises a first up insulating ring 343 and a first down insulating ring 344 which are sleeved between the first electrode 341 and the second electrode 342 respectively. Referring to
When assembling, the two extending ends of the heating wire 312 are respectively inserted between the first down insulating ring 344 and the second electrode 342 and between the first down insulating ring 344 and the first electrode 341. Therefore, the welding connection in prior art is not adopted when the heating wire 312 is assembled, and the atomizer 3 can be assembled without complex operations. Thus, it is convenient to assemblers, the assembling efficiency can be improved, production cost can be saved and the requirement to assemblers is reduced. By the means of clamping, the first electrode connecting element 34 is enabled to deliver power to the heating wire assembly 31, which is convenient for assembling, can improve the stability of the electrical connection between the first electrode connecting element 34 and the heating wire assembly 31 and can prevent rosin joint that will cause the atomizer 3 failed to work from happening.
Furthermore, a vent hole (unlabeled) is extended through the second electrode 342 along an axial direction and is connected to the fixed sleeve 33. The vent hole is the smoke outlet of the atomizer 3. The smoke produced by the heating wire assembly 31 is discharged through the vent hole. The arrows in

Specifically, an opening is defined on one end of the oil container 2, facing the atomizer 3. The oil delivery mechanism 32 is inserted into the oil container 2 through the opening. The elastic sealing element 37 is sleeved on the oil conduit 321, corresponding to the opening, and is configured to seal oil.
The bottom cap 38 is fixed in one end of the oil conduit 321, wherein the end of the oil conduit 321 is inserted into the oil container 2. A through-hole (unlabeled) is defined in the bottom cap 38 along an axial direction and is configured to provide flow path for oil. The bottom cap 38 is mainly configured to seal the oil conduit 321 and to avoid the oil latch element 322 in the oil conduit 321 slipping off from one end of the oil conduit 321 to impact the oil absorbing effect of the oil latch element 322.

Therefore, the situation that the users are scalded by the heat produced by atomizer when atomizing the oil can be avoided and the using safety of the electronic cigarette is improved. Additionally, the users may naturally clamp the battery assembly 4 when using the electronic cigarette to smoke, and may avoid clamping the heated atomizer 3. Therefore, using the electronic cigarette, the situations that hands of the users are scalded can be avoided. The temperature of the real cigarette is simulated effectively by the electronic cigarette of the present invention, and the using experience of smoking is improved.
(7) as the oil container is provided opposite to the mouthpiece, the oil container is free from the external clamping force. The oil is output stably to the atomizer from the oil container, so the stability of the smoke produced is improved effectively.
(8) the smoking end of the electronic cigarette is detachably connected to the battery assembly, so it is convenient for users to disassemble and clean the smoking end.
Referring to
The differences between the electronic cigarette of the embodiment and the electronic cigarette of above embodiment are as follows: in the embodiment, the battery assembly 4 and the atomization assembly are arranged side by side; the atomization sleeve 30 of the atomization assembly and the battery bracket 42 are integrally formed; a protection cover 390 is provided out of the atomization sleeve 30, the protection cover 390 can slide along the axial direction of the electronic cigarette body and covers the outer wall of the oil container 2; a second electrode connecting element 391 is provided in the atomization sleeve 30 and is electronically connected to the first electrode connecting element 34 and the battery 41; a key switch 44 electronically connected to the first electrode connecting element 34 and the battery 41, configured to control the battery 41 to supply power to the heating wire 312, is provided on the side surface of the battery assembly 4.
As the liquid delivery element of the heating wire assembly is fixed along the axial direction of the atomizer, and the oil container is detachably connected to one end of the electronic cigarette body, opposite to the smoking end, the electronic cigarette in the embodiment has the advantageous effects corresponding to above embodiment. Additionally, as the battery assembly and the atomization assembly are arranged side by side, the length of the electronic cigarette is shorter and it is convenient to carry. The oil container 2 can be protected better through the protection cover 390.
