Embodiment Construction

[0035] If a battery cell is damaged inside the energy storage device, it may produce gases through a venting process (also known as thermal runaway) that may increase the pressure inside the energy storage device and generate overheating. If an energy storage device is used inside an aerosol generating device, injury to the intended user should be avoided at all costs. To avoid this, it is important to release the gas to the outside of the battery and energy storage device. One obvious way of releasing the gas is to provide one or more vents in the energy storage device, allowing the gas to flow to the outside. However, such vents pose a safety risk because they can allow water or liquid (eg, e-liquid) to enter the energy storage device and potentially cause safety issues (such as short circuits). Furthermore, the one or more vent holes may not provide any indication to a prospective user that a battery cell has been detected to have been vented unless the battery cell become...

Abstract

The invention provides an energy storage assembly device for an aerosol-generating device, the energy storage assembly device comprising: a housing intended for accommodating a battery; an exhaust member configured to exhaust the pressurized gas from inside the housing when a predetermined pressure is reached in the housing; the housing has an elongated shape. The housing includes a first plurality of holes blinded by a blinding member on a circumference of the housing at a first end inside which is not filled with the battery, the first plurality of holes and the blinding member each being part of an exhaust component.

Description

technical field [0001] The present invention is in the field of aerosol generating devices, and more particularly in the safety aspects of using batteries in aerosol generating devices. Background technique [0002] Prior art reference US 2017 / 0170439 A1 relates generally to an energy storage device. More specifically, it relates to an energy storage device assembly constructed with: a housing or container; a current interrupt device configured with the housing to electrically disconnect the energy storage assembly from passing current through its components and an exhaust component / means configured to exhaust pressurized gas. The vent region substrate is configured to be attached to the housing (e.g., cover and / or body), and the vent is configured to open in a predetermined manner such that the substrate tears along a predetermined path across / around at least a portion of the substrate / detach. In the disclosure of this document, the vent includes a vent panel (e.g., a r...
