Abstract
An electronic cigarette includes a main body and a replaceable cartridge that can be disassembled from the main body. The main body includes a laser. The cartridge includes a liquid store and an absorber configured to be heated by radiation emitted by the laser in order to vaporise a vaporisable medium. An enabling device is also provided to enable propagation of radiation from the laser to the absorber when the cartridge is assembled to the main body and to inhibit propagation of radiation from the laser to the absorber when the cartridge is disassembled from the main body.
Claims16
An electronic cigarette comprising:
- a main body comprising a vaporising light source;
- a cartridge configured to be removably assembled to the main body, wherein the cartridge includes a liquid store for storing a vaporisable medium and an absorber configured to be heated by radiation emitted by the vaporising light source in order to vaporise the vaporisable medium;
- and
- an enabling device adapted to enable propagation of radiation from the vaporising light source to the absorber only when the cartridge is assembled to the main body, such that the vaporising light source cannot propagate light outside the electronic cigarette when the cartridge is disassembled from the main body, and wherein the enabling device comprises a light guide connected to the cartridge, wherein, when the main body and the cartridge are assembled together the light guide is positioned to direct radiation emitted by the vaporising light source towards the absorber.
A cartridge for use in an electronic cigarette comprising:
- a liquid store;
- an absorber configured to be heated by radiation emitted by a vaporising light source in a main body of the electronic cigarette in order to vaporise a vaporisable medium;
- and
- an enabling device adapted to enable propagation of radiation from the vaporising light source to the absorber when the cartridge is assembled to the main body and to inhibit propagation of radiation from the vaporising light source to the absorber when the cartridge is disassembled from the main body, wherein the enabling device comprises a light guide, the light guide having a light input surface configured to be optically coupled with a light emitter and an output surface configured to be optically coupled with the absorber.
An electronic cigarette main body comprising:
- a vaporising light source configured to emit radiation towards an absorber in a cartridge in order to vaporise a vaporisable medium;
- and
- an enabling device adapted to enable propagation of radiation from the vaporising light source to the absorber when the cartridge is assembled to the main body and to inhibit propagation of radiation from the vaporising light source to the absorber when the cartridge is disassembled from the main body.
