Abstract:
1. An LED torch, comprising: a hand-held housing; an electric power arrangement which comprises an electric power source received in said hand-held housing and an electrical-powered operation head which is electrically linked to said electric power source and is located at an outer wall of said hand-held housing; and a multifunctional head unit which comprises an inhaler unit and an LED illumination unit detachably and interchangeably coupled with said hand-held housing to operatively link to said operation head, wherein said inhaler unit has a mouthpiece and a treatment cavity for receiving a treatment element therein, wherein when said inhaler unit is operatively coupled with said operation head of said electric power arrangement, said operation head forms a heating head for heating said treatment element in said treatment cavity so as to extract said treatment element for inhalation of an ingredient thereof via said mouthpiece, wherein when said LED illumination unit is operatively coupled with said operation head of said electric power arrangement, said operation head forms an electrical adapter to electrically link said LED illumination unit with said electric power source for generating illumination light, wherein said electric power arrangement further comprises a control circuit controllably linked between said operation head and said electric power source, and an automatic switch which is provided at said operation head and is controlled by said control circuit to selectively switch an operation between said inhaler unit and said LED illumination, wherein said automatic switch comprises a magnetic sensor switch provided at said operation head and a magnetic element provided at said inhaler unit, wherein when said inhaler unit is detachably coupled with said operation head, said magnetic sensor switch is switched on by detecting a presence of magnetic field via said magnetic element, such that said control circuit automatically configures said operation head as said heating head for heating up said treatment element, wherein when said LED illumination unit is detachably coupled with said operation head, said magnetic sensor switch is switched off by detecting no magnetic field at said LED illumination unit, such that said control circuit automatically configures said operation head as said electrical adapter to electrically connect with said LED illumination unit.
