ELECTROMAGNETIC SKIN TREATMENT DEVICE
First Claim
1. A hand-held electromagnetic skin treatment device comprising:
- a source of electromagnetic radiation;
an energy supply electrically coupled to the source of electromagnetic radiation;
a controller arranged to control a supply of energy from the energy supply to the source of electromagnetic radiation, wherein responsive to the supply of energy, the source of electromagnetic radiation outputs electromagnetic radiation;
a housing having a watertight portion arranged to enclose the source, the energy supply and the controller for allowing use of the hand-held electromagnetic skin treatment device in a wet environment, the housing further having a cooling compartment with an interior thereof arranged in fluid communication with an exterior of the housing in the wet environment via air and water flow through passages of the cooling compartment;
an internal heat exchanger enclosed within the watertight portion of the housing in heat conducting relation with the source;
an external heat exchanger disposed outside the watertight portion of the housing, and located at least partially in the cooling compartment, in the wet environment; and
a heat path from the internal heat exchanger to the external heat exchanger that passes hermetically through the wall of the watertight portion of the housing, wherein together the (i) internal heat exchanger, (ii) heat path and (iii) external heat exchanger that is located at least partially in the cooling compartment jointly provide cooling of the source of electromagnetic radiation arranged in the watertight portion of the housing.

Abstract
A hand-held skin treatment device comprises a source of electromagnetic radiation, an energy supply electrically coupled to the source and a controller arranged to control the energy supplied to the source of electromagnetic radiation. The source, the energy supply and the controller are enclosed in a watertight housing allowing use of the hand-held skin treatment device in a wet environment. To provide sufficient cooling of the source, the device comprises an internal heat exchanger in heat conducting relation with the source, an external heat exchanger outside of the watertight housing, and a heat path from the internal heat exchanger to the external heat exchanger that passes hermetically through a wall of the watertight housing. With this device, users can conveniently integrate their skin treatment activities with the daily washing routine in a shower or bath. The device is especially useful in the context of hair removal.
