The present invention provides a cigarette smoke filtration apparatus. The said apparatus includes a telescopic cigarette holding unit for holding a cigarette which may be retracted into a housing when the apparatus is not in use. The apparatus includes a filtration unit to filter the smoke from the cigarette before being discharged. The apparatus includes one or more fans to introduce fresh air into the housing to allow for the cigarette to burn and also to suck smoke out of the housing. The apparatus also includes an ignition coil to light the cigarette and a wire mesh to trap ash from the burning of the cigarette. The apparatus further includes a valve assembly having one or more one-way exhaling valves for exhaling the smoke out and one one-way for inhaling valve for inhaling the smoke from the burning cigarette because users like resistance when inhaling but not when exhaling.

The present disclosure is directed to a heater including: a resistor including a heat-generating portion; a lead joined to an end portion of the resistor; and an insulating base covering the resistor and the lead. The heater includes a connection portion in which the resistor and the lead overlap each other in a direction perpendicular to an axial direction of the lead, and a boundary between the resistor and the lead has a curved shape when the connection portion is seen in a cross section perpendicular to the axial direction.

A handheld computer case having an integral lighter for providing a flameless lighter in a case for a mobile phone includes a case body defining a rigid housing sized to fit a conventional handheld computer, a lighter actuator for selectively availing and activating an electric lighter, and a lighter housing in which the electric lighter is disposed. In operation, a user may apply manual force to mechanically actuate the lighter actuator, thereby causing both the lighter housing to open and expose the electric lighter and an electrical switch to direct electricity from an internal battery to a heating element which defines the electric lighter. Once the user is finished with the lighter, the manual force may be removed to cause the lighter housing to automatically close and the flow of electricity to the heating element to be interrupted.

The present disclosure relates to a solid-fuel cooker, such as a barbecue, comprising: a body defining a chamber configured to act as a firebox for combustion of solid fuel, such as charcoal or briquettes; a fuel support structure for supporting the solid fuel in the chamber; and an ignition system for igniting the solid fuel supported by the support structure. The ignition system comprises at least one electric heating element mounted to the body and located in or adjacent to the chamber for heating the solid fuel supported by the support structure, the at least one electric heating element configured to be switched between an electrically energized (i.e. switched on) state and an electrically de-energized (i.e., switched off) state. The at least one electric heating element is configured to transfer heat to the solid fuel supported by the support structure to ignite the solid fuel when the switch is operated to the electrically energized (i.e. switched on) state.
