Detailed Description

The following description of the preferred embodiments of the present invention is a preferred embodiment of the present invention, and is not intended to limit the present invention. The description of the preferred embodiments of the present invention is intended only as an illustration of the general principles of the invention. The present invention will be described in further detail with reference to the accompanying drawings and examples.

As shown in fig. 1 to 9, a core member 10 of an electronic cigarette according to a preferred embodiment of the present invention is shown. The core component 10 of the electronic cigarette may be supported in a housing assembly of the electronic cigarette. The core component 10 of the electronic cigarette comprises a main housing 20, an atomizer 30 and a smoke leakage prevention device 40.

The main housing 20 has a nozzle portion 21, an atomizer portion 22, a connecting portion 23 extending between the nozzle portion 21 and the atomizer portion 22, a liquid storage chamber 24 formed in the connecting portion 23, and an air inlet 25. The main housing 20 also has an outer boundary wall 27 and a vapour release passage 26 extending from the atomizer section 22 to the connection section 23. The atomizer 30 may be supported in the atomizer portion 22 of the main housing 20.

The smoke leakage prevention means 40 includes at least one discharge port 41 formed in the main housing 20. The drain 41 connects the outer boundary wall 27 to the atomizer 30 so that condensate formed on the inner surface 271 of the outer boundary wall 27 of the main housing 20 can be arranged to be guided back through the drain 41 to the atomizer 30.

According to the preferred embodiment of the present invention, the electronic cigarette core component 10 of the present invention can be mounted to the housing components of various electronic cigarettes. In this way, the electronic cigarette core piece 10 may be actuated by the housing assembly by different conventional actuation mechanisms.

Switches

51, 52 may be provided on main housing 20 for engagement with the respective housing assembly. According to the preferred embodiment of the present invention, the electronic smoking component 10 of the present invention includes an air passage switch 51 and a flue switch 52 disposed on the main housing 20 for switching on the supply of air and tobacco tar.

The electronic core 10 of the electronic core 10 has a long configuration when viewed from the side. The mouthpiece section 21 of the main housing 20 is ergonomically designed to fit the mouth of the user. The main housing 20 also includes a steam outlet 28 formed in the mouthpiece section 21 for allowing steam to exit therethrough. The steam outlet 28 communicates with the steam release passage 26 such that steam passing through the steam release passage 26 can flow out of the main housing 20 through the steam outlet 28. According to a preferred embodiment of the present invention, the mouthpiece section 21 is provided at the upper end of the main casing 20.

On the other hand, the atomizer portion 22 of the main housing 20 is for accommodating the atomizer 30. The atomizer 30 includes a heating element 32 for evaporating the e-liquid or condensate collected by the smoke leak prevention device 40. When the smoke switch 52 is turned on, the heating element 32 atomizes the e-liquid being controllably released from the liquid storage chamber 24.

The smoke leakage prevention means 40 includes two discharge ports 41 provided in the atomizer portion 22 of the main housing 20. Each discharge port 41 communicates the outer boundary wall 27 of the main housing 20 with the atomizer 30. When the e-cigarette is deactivated, residue or condensate formed on the inner surface 271 of the outer boundary wall 27 of the main housing 20 is directed to flow through the discharge opening 41 and ultimately back to the atomizer 30.

As shown in fig. 6 and 7, the steam release channel 26 has a tapered cross-sectional shape in the front view such that the inner side wall 261 of the steam release channel 26 extends obliquely from the suction nozzle portion 21 to the atomizer portion 22. The vapor collection chamber 29 is disposed between the outer sidewall 262 of the vapor release passage 26 and the corresponding inner surface 271 of the outer boundary wall 27 of the main housing 20. Due to the conical structure of the steam release channel 26, the outer side wall 262 may be slightly inclined. Likewise, the inner surface 271 of the outer boundary wall 27 may also be slightly sloped such that the thickness of the vapor collection chamber 29 gradually increases from the nozzle portion 21 to the atomizer portion 22. In this preferred embodiment, two vapor collection chambers 29 are provided in the main housing 20, wherein the vapor collection chambers 29 are provided at the front and rear sides of the vapor release passage 26, respectively.

As shown in figure 4, the core member 10 of the e-cigarette further comprises a pressure equalisation device 60 comprising a pressure equalisation tube 61 extending from the air passage switch 51 to the liquid reservoir 24. Pressure balancing device 60 also includes at least one air gap 62 formed between air passage switch 51 and main housing 20. Thus, when the air path switch 51 is actuated (e.g., depressed), air may flow from the ambient to the pressure equalization tube 61. In other words, the air gap 62 equalizes the pressure between the ambient environment and the fluid reservoir 24. This allows for a more efficient and smooth flow of liquid from the liquid reservoir 24 to the atomizer 30.

When the smoke switch 52 is actuated (e.g., depressed), smoke liquid is directed from the liquid reservoir 24 to the atomizer 30 to generate smoke. Since the pressure in the liquid reservoir 24 is regulated to be in equilibrium with the pressure in the surrounding environment, the liquid smoke will be supplied to the atomizer 30 in a very smooth and efficient manner.

The smoke leakage prevention apparatus 40 further includes a plurality of pieces of support members 44 respectively provided at the lower end portions of the vapor collection chamber 29, wherein each support member 44 has an extension portion 441 extending in the main casing 20 to define the corresponding discharge port 41 as a gap formed between the extension portion 441 and the inner surface 271 of the outer boundary wall 27 of the main casing 20.

Condensate or residue formed on the inner surface 271 of the outer boundary wall 27 of the main housing 20 may be directed to the drain 41 so that the condensate may pass through the drain 41 and eventually flow back to the atomizer 30 for re-evaporation.

As shown in fig. 6 and 9, the smoke leakage prevention device 40 further includes a residue discharge port 43 and a residue storage chamber 42 provided in the main housing 20 at a position below the atomizer portion 22 for temporarily storing residual condensate that is not guided and collected through the discharge port 41. A residue discharge port 43 communicates the outer boundary wall 27 with the residue storage chamber 42.

Specifically, when the e-cigarette stops operating, a certain amount of condensate has been directed through the drain 41. The remaining condensate may flow through drain 41 and toward the bottom of main housing 20. The residual condensate is then directed through the residual drain 43 and eventually collects in the residual storage chamber 42. The residue storage chamber 42 communicates with the atomizer 30 such that residual condensate stored in the residue storage chamber 42 may be directed to re-enter the atomizer 30 for re-evaporation.

The smoke leakage prevention device 40 further includes a base member 45 supported in the main housing 20 to define the residue discharge port 43. The base member 45 has a central portion 451, the central portion 451 having a central passage 4511 and two extension flaps 452 extending from the central portion 451 to form the residue discharge opening 43 as a space between the extension flaps 452 and the inner surface 271 of the outer boundary wall 27, respectively.

Further, as shown in fig. 8, the smoke leakage prevention means 40 further comprises a vapor control member 47 installed at the top of the vapor release passage 26. The steam control member 47 has a steam channel 471, the steam channel 471 communicating with the steam release channel 26 such that steam from the atomizer 30 is arranged to pass through the steam channel 471. As shown in fig. 6 and 8, the steam channel 471 has a tapered cross-sectional shape when viewed from the front, such that the diameter of the steam channel 471 gradually decreases from the top to the bottom thereof.

The vapor control member 47 has an inclined surface 472, the inclined surface 472 facing downward in the vapor release passage 26 toward the atomizer 30. When the e-cigarette ceases to operate, a small amount of condensate or liquid residue forms on the inclined surface 472 or the inner side wall 261 of the vapor release channel 26. This condensate or residue is directed to flow back along the steam release channel 26 to the atomizer 30 and is provided at its bottom end portion for re-evaporation.

It will therefore be appreciated that the drain 41 and the residual drain 43 are designed to collect condensate that forms on the inner surface 271 of the outer boundary wall 27 of the main housing 20, thereby forming a double protection to collect and re-use condensate that remains on the inner surface 271 of the outer boundary wall 27 and thus prevent excessive accumulation of condensate in any part of the main housing 20. As a result, the possibility of condensate leaking from main housing 20 (particularly when the e-cigarette is not in use) may be minimized.

In addition, the main housing 20 also has a tobacco port 290 in communication with the liquid storage chamber 24, and the electronic cigarette core piece 10 further includes a tobacco seal cap 70 movably mounted to the main housing 20 to removably seal the tobacco port 290. In the preferred embodiment, the smoke seal cap 70 is connected to the steam control member 47 and is movable relative to its pivot axis.

While the invention has been illustrated and described in terms of a preferred embodiment and several alternatives, it is not intended that the invention be limited by the specific description set forth herein. Other additional alternative or equivalent components may also be used in the practice of the invention.
