Description

TECHNICAL FIELD OF THE INVENTION

The present application generally relates to electronic cigarettes.

BACKGROUND OF THE INVENTION

As shown in FIG. 1, the bottom side of the base of the current electronic cigarette generally has four holes 10 a/10 b for air inlet. However, the oil may leak out from the four air inlet holes 10 a/10 b at the bottom of the base when the heat wire fails to lock the oil.
In addition, the oil cup assembly and the base assembly are generally connected by threading. The user may unscrew the atomizer when smoking. It is easy to separate the oil cup assembly from the base assembly, making the oil to be leaked directly from the oil cup easily
Sometimes the manufacture may add a silica gel between the oil cup assembly and the base assembly. However, it is hard to separate the oil cup assembly and the base assembly. The oil cup assembly may be broken when using too much strength for separation, making the oil be leaked out from the oil cup assembly.
Therefore, a need remains for an electronic cigarette to provide a more convenient structure for keeping the oil inside the electronic cigarette.

DETAILED DESCRIPTION OF DISCLOSED EMBODIMENTS

Reference will now be made in detail to the present representative embodiments of the present application, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers are used in the drawings and the description to refer to the sane or like parts.
FIG. 2A is a perspective view of an oil cup assembly 100 of the present application. FIG. 2B is a perspective view of a base assembly 200 of the present application. FIG. 3 is a cross-sectional view of the electronic cigarette of the present application.
In the present application, an overall size of the electronic cigarette is 11*50.35 mm or 11*60.15 nm depending on a capacity of the oil cup tank which will be described later. A resistance of the electronic cigarette is 1.4 ohm as an example but not limited either.
The oil cup assembly 100 comprises an oil tank 110, a mouth piece 120, a fixed portion 130 and an oil cup tube 140.
The oil tank 110, the mouth piece 120 and the oil cup tube 140 are made of glass but is not limited. The capacity of the oil cup tank 110 is 0.5 mL or 1.0 mL as an example but is not limited. If the capacity of the oil tank 110 is 0.5 mL, the overall size of the electronic cigarette will be 11*50.35 mm. If the capacity of the oil tank 110 is 1.0 mL, the overall size of the electronic cigarette will be 11*60.15 mm. However, the capacity of the oil tank 110 and the overall size of the electronic cigarette are not limited. The present application here only provides two embodiments as examples. The mouth piece 120 is coupled to the oil tank 110. Specifically, the mouth piece 120 and the oil tank 110 are molded integrally.
Referring to FIG. 2A and 3, the fixed portion 130 comprises a fixed ring 132, a fixed column 134 and a positioning column 136. The fixed ring 132 comprises a fixed ring body 132 a and at least one protrusion 132 b coupled to the fixed ring body 132 a. Specifically, the at least one protrusion 132 b forms at least one slot for locking snaps 220. The details about the mechanism of the snaps 220 will be described later with FIG. 2B. The fixed column 134 is made of glass. In detail, the fixed column 134 and the oil tank 110 are molded integrally. The fixed ring 132 is wrapped around the fixed column 134. The positioning column 136 is made for making the base assembly 200 to be coupled with the oil cup assembly 100 more accurately and conveniently.
Referring to FIG. 2B and 3, the base assembly 200 comprises a sleeve 210, a pair of snaps 220, an electrode 230, a heat wire 240. a fabric 250, a central tube 260 and an insulator 270.
The sleeve 210 comprises an upper portion 212, a lower portion 214, a protruded portion 216 and at least one air inlet hole 218. The upper portion 212, the lower portion 214 and the protruded portion are molded integrally but is not limited. The air inlet hole 218 is located at the lower portion 214. Rather than the electronic cigarette 10 as shown in FIG. 1 which the air inlet holes 10 a/10 b are located at the protruded portion, the air inlet hole 218 of the present application is located at the lower portion 214, providing more room for oil. A size of the air inlet hole 218 is 2 mm²as an example but is not limited. The detail of the above structure will be described later with FIG. 4B. In the present application, the sleeve 210 is a silicon sleeve as an example but is not limited.
The pair of snaps 220 are partially coupled to the lower portion 214 of the sleeve 210 and removably coupled to the fixed portion 130. Specifically, the pair of snaps 220 is coupled to the at least one protrusion 132 b of the fixed ring 132. The oil cup assembly 100 and the base assembly 200 may not be rotate relative to each other since the at least one protrusion 132 b forms at least one slot for locking snaps 220. In the present application, the pair of snaps 220 is made of plastic in order to deform for locking with the fixed portion 130. However. the material of the snaps 220 is not limited as long as the snaps 220 could be removably coupled to the fixed portion 130. In addition, the amount of the snaps 220 is not limited either. The electronic cigarette of the present application could comprise one or more than one snap 220.
The electrode 230 is disposed inside the protruded portion 216 for contacting to the power.
The heat wire 240 is located inside the upper portion 212 of the sleeve 210. The fabric 250 is disposed between the heat wire 240 and the sleeve 210. In the present application, the fabric 250 is a non-woven fabric as an example.
The central tube 260 is located between the upper portion 212 and the lower portion 214 for stabling the whole structure. The insulator 270 is coupled between the electrode 230 and the protruded portion 216.
FIGS. 3-4B are cross-sectional views of the electronic cigarette of the present application.
As shown in FIG. 4A, the oil 50 is located within the oil cup tank 110. When the heat wire assembly fails to absorb the oil falling, the oil 50 may flow into the bottom area for storage as shown in
FIG. 4B. The oil may only be leaked from the air inlet hole 218 when the amount of the oil 50 flowing down exceeds the storage area.
Based on the above, the electronic cigarette of the present application utilizes the snap-lock structure to avoid the oil be leaked out. Specifically, after the oil cup assembly and the base assembly are assembled, the base assembly and the oil cup assembly may not be loosened due to the external fastening of the fixed portion to the internal fastening of the snaps.
In addition, the oil may be hard to leak out since the air inlet hole is located at lower portion of the base assembly which is relatively higher than common electronic cigarette as shown in FIG. 1.
It will be apparent to those skilled in the art that various modifications and variations can be made to the structure of the present application without departing from the scope or spirit of the present application. In view of the foregoing, it is intended that the present application cover modifications and variations of this application provided they fall within the scope of the following claims and their equivalents.
