## Abstract

A device for evaporating volatile substances includes a wick (1) impregnated with volatile substances and a heating element (2) that heats the wick (1) for purposes of evaporating said volatile substances. The device further includes a reflective element (3) for reflecting the heat from the heating element (2) to said wick (1). The heating element (2) can be preferably a resistor or a ceramic heater. The reflective element (3) directs substantially all the heat provided by the heating element to the wick, thereby preventing an excessive rising of the temperature of the surface of the device.

## Claims

### Claim 1

A heating component for placement inside the housing of a device for evaporating volatile substances, the heating component comprising:
a cylindrical heating element having a core sized and shaped to receive a wick impregnated with a volatile substance and that heats the wick for evaporating said volatile substances;
a cylindrical reflective element for reflecting the heat from the heating element to the wick; and
wherein when the heating element receives the wick, the heating element is located between the wick and the reflective element.

### Claim 2 (depends on 1)

The heating component according to claim 1, wherein the heating element is a resistor or a ceramic heater.

### Claim 3 (depends on 1)

The heating component according to claim 1 wherein the reflective element comprises a metallic surface.

### Claim 4 (depends on 1)

The heating component according to claim 1 wherein said heating element and said reflective element are joined by a base.

### Claim 5 (depends on 1)

The heating component according to claim 1 wherein said reflective element is made from two layers, a reflective layer and a base layer.

### Claim 6 (depends on 1)

The heating component according to claim 1 further comprising a thermal cutoff component connected to the reflective element.

### Claim 7 (depends on 1)

The heating component according to claim 1 further comprising a negative coefficient temperature element in contact with the reflective element for measuring the temperature of the reflective element and modifying a power supply to the device by an electronic circuit according to the measured temperature.

### Claim 8 (depends on 2)

The heating component according to claim 2, wherein the reflective element comprises a metallic surface.
