Patent Description:
E-vaping devices, also referred to herein as electronic vaping devices (EVDs) may be used by adult vapers for fluid portable vaping. An e-vaping device may include a reservoir that holds pre-vapor formulation and a vaporizer assembly that may heat pre-vapor formulation drawn from the reservoir to generate a vapor.

Some e-vaping devices are configured to enable replenishment of the pre-vapor formulation held in a reservoir of the e-vaping device (that is, refilling of the reservoir).

<CIT> describes an atomiser for an electronic cigarette, the atomiser comprising a housing unit, an atomisation device, a base assembly detachably connected to the bottom of the housing unit, and a cover body assembly detachably connected to the top of the housing unit. The housing defines a tobacco liquid chamber for storing a tobacco liquid. The tobacco liquid chamber is partially defined by a first casing body, which defines a first liquid guide hole. The atomiser also comprises a second casing body positioned inside the first casing body and surrounding the atomisation device. The second casing body defines a second liquid guide hole.

During use of the atomiser, the first liquid guide hole is aligned with the second liquid guide hole to allow the tobacco liquid inside the tobacco liquid chamber to flow to the atomisation device.

To replace the atomisation device, a user may unscrew the base assembly from the housing unit. The base assembly is configured to engage the second casing body during rotation of the base assembly so that removal of the base assembly rotates the second casing body with respect to the first casing body. This rotation of the second casing body brings the second liquid guide hole out of alignment with the first liquid guide hole so that tobacco liquid may no longer flow from the tobacco liquid chamber to the atomisation device.

The atomiser also comprises a liquid refill port that is covered by the cover body assembly during normal use of the atomiser. To refill the tobacco liquid chamber, a user may unscrew the cover body assembly from the housing unit to reveal the liquid refill port. The cover body assembly is configured to engage the first casing body during rotation of the cover body assembly so that removal of the cover body assembly rotates the first casing body with respect to the second casing body. This relative rotation between the first and second casing bodies brings the first liquid guide hole out of alignment with the second liquid guide hole so that tobacco liquid may no longer flow from the tobacco liquid chamber to the atomisation device while the tobacco liquid chamber is being refilled.

As shown in <FIG>, the fluid port <NUM> enables fluid communication between the reservoir <NUM> and an exterior of at least the reservoir <NUM>, which in some examples may be independently of the vaporizer assembly <NUM>, the conduit <NUM>, or both. Therefore, the reservoir assembly <NUM> may be configured to enable refilling of the reservoir <NUM> via introduction of pre-vapor formulation into the reservoir <NUM> through at least the fluid port <NUM>, thereby enabling pre-vapor formulation to be introduced into the reservoir <NUM> independently of the vaporizer assembly <NUM>, the conduit <NUM>, or both.

In some example embodiments, the isolation structure <NUM> is movable to expose either the fluid port <NUM> or the fluid port <NUM>, but not both at a given time. In some example embodiments, the isolation structure <NUM> is configured to preclude simultaneous exposure of fluid port <NUM> and fluid port <NUM>. In some example embodiments, the isolation structure <NUM> is configured to move to cover both the fluid port <NUM> and the fluid port <NUM> at the same time. In some example embodiments, fluid port <NUM> may include more than one port (for example, there may be multiple fluid ports <NUM>), the fluid port <NUM> may include more than one port (for example, there may be multiple fluid ports <NUM>), or the fluid port <NUM> and the fluid port <NUM> may each include more than one port, and the functionality described above can similarly apply.

For example, the isolation structure <NUM> may be configured to move to expose the reservoir <NUM> to either an exterior of the reservoir <NUM> via one or more fluid ports <NUM> while covering the one or more fluid ports <NUM>, to expose the reservoir <NUM> to the vaporizer assembly <NUM> via the one or more fluid ports <NUM> while covering the one or more fluid ports <NUM>, or to isolate the reservoir <NUM> from both the exterior of the reservoir <NUM> and the vaporizer assembly <NUM> by covering both the one or more fluid ports <NUM> and the one or more fluid ports <NUM> at the same time.

As shown in <FIG>, one or more portions of the isolation structure <NUM> may be coupled to an interface assembly <NUM> so that the isolation structure <NUM> is configured to move based on manual (for example, adult vaper) manipulation of the interface assembly <NUM>.

In some example embodiments, the isolation structure <NUM> may omit the first or second structures <NUM>, <NUM>. In some example embodiments, for example where the isolation structure <NUM> includes the second structure <NUM> but omits the first structure <NUM>, the second structure <NUM> may be referred to as a "first structure" of the isolation structure <NUM>.
