Portable Liquid Vaporizer
A portable liquid vaporizer ( 1 ) comprises a reservoir ( 10 ) for holding a liquid to be vaporized; a heater ( 12 ) for vaporizing the liquid; a mouthpiece ( 3 ) for withdrawing the vapor; and an air path ( 30 ) extending through the vaporizer ( 1 ), comprising a heating section ( 31 ) and a cooling section ( 32 ), wherein the heating section ( 31 ) extends along the heater ( 12 ) and the cooling section ( 32 ) extends directly downstream from the heater ( 12 ) to the mouthpiece ( 3 ).
1 . A Portable liquid vaporizer comprising:
a reservoir for holding a liquid to be vaporized;
a heater for vaporizing the liquid;
a mouthpiece for withdrawal of the vapor; and
an air path extending through the vaporizer, comprising a heating section and a cooling section, wherein the heating section extends along the heater and the cooling section extends directly downstream from the heater to the mouthpiece,
wherein the cooling section has an effective length that is sufficient for allowing the vapor to cool down and leave the mouthpiece at 40° C. or less above environmental temperature upon withdrawal of the vapor.
2 . The portable liquid vaporizer of claim 1 , wherein the cooling section has an effective length (L) that is at least 50 of the length (L) of the vaporizer and/or an effective length (L) that is at least 50 mm.
3 . The portable liquid vaporizer of claim 1 , wherein, when the mouthpiece defines the top, the heater is located in the lower half of the vaporizer.
4 . The portable liquid vaporizer of claim 1 , wherein a power source is arranged between the heater and the mouthpiece.
5 . The portable liquid vaporizer of claim 1 , wherein the longitudinal extension of the cooling section is offset from the longitudinal axis of the vaporizer.
6 . The portable liquid vaporizer of claim 1 , wherein the air path extends from the bottom of the vaporizer to the mouthpiece.
7 . The portable liquid vaporizer of claim 1 , wherein the air path extends through the reservoir upstream from the heating section.
8 . A Portable liquid vaporizer comprising:
a reservoir for holding a liquid to be vaporized;
a heater for vaporizing the liquid;
a mouthpiece for withdrawal of the vapor; and
an air path extending through the vaporizer, comprising a heating section and a cooling section, wherein the heating section extends along the heater and the cooling section extends directly downstream from the heater to the mouthpiece,
wherein the cooling section comprises an insert for absorbing heat, filtering the vapor, catching droplets and/or flavoring the vapor.
9 . The portable liquid vaporizer of claim 8 , wherein the insert is configured to guide the vapor helically through the cooling section, and/or wherein the insert comprises a flavored body, preferably a flavored mesh-like or sponge-like body.
10 . A portable liquid vaporizer comprising:
a reservoir for holding a liquid to be vaporized;
a heater for vaporizing the liquid;
a mouthpiece for withdrawal of the vapor;
an air path extending through the vaporizer, comprising a heating section and a cooling section, wherein the heating section extends along the heater and the cooling section extends directly downstream from the heater to the mouthpiece;
a control unit for controlling the heater; and
one or more temperature sensors configured to sense the temperature of the vaporized liquid in the cooling section,
wherein, when the one or more temperature sensors senses a temperature exceeding a predetermined threshold, the control unit is configured to reduce or stop the heating power of the heater.
11 . The portable liquid vaporizer of claim 10 , wherein the one or more temperature sensors are located in the cooling section adjacent to the heater and/or adjacent to the mouthpiece.
