Abstract

A wax warmer includes a body, an electrical assembly positioned within an interior space of the body, and a sleeve positioned within the interior space. The sleeve surrounds and provides a barrier to the electrical assembly.

Claims

1. A wax warmer, comprising:

a body;

a top plate disposed adjacent a top end of the body;

a base plate disposed adjacent a bottom end of the body;

a reservoir supported by the top end of the body, the reservoir configured to receive a wax melt;

an electrical assembly positioned within an interior space of the body; and

a sleeve forming an electrical barrier positioned within the interior space and surrounding the electrical assembly, wherein a top edge of the sleeve is in contact with the top plate and a bottom edge of the sleeve is in contact with the base plate, and wherein the sleeve provides a barrier to the electrical assembly.

2. The wax warmer of claim 1, wherein the interior space is defined between the top plate, the base plate, and the body.

3. The wax warmer of claim 2, wherein the sleeve is integrally coupled to at least one of the base plate and the top plate.

4. The wax warmer of claim 1, wherein the sleeve is annular in shape.

5. A wax warmer, comprising:

a body;

an electrical assembly positioned within an interior space of the body; and

an annular sleeve including a first side edge and a second side edge, wherein a groove is provided adjacent the first side edge configured to receive a tongue provided adjacent the second side edge, and wherein the annular sleeve is positioned within the interior space and surrounding the entire electrical assembly within the body.

6. The wax warmer of claim 5, wherein the electrical assembly includes a heat source that produces a heat output between about 10 watts and about 20 watts, and wherein the annular sleeve has a melting point of between about 350 to about 510 degrees Fahrenheit.

7. The wax warmer of claim 5, wherein the annular sleeve is distanced from the electrical assembly, the distance being measured from an interior surface of the annular sleeve to an exterior surface of the electrical assembly, the distance having a minimum length of about 0.3 centimeters.

8. The wax warmer of claim 7, wherein the electrical assembly includes a heat source and a ratio of the heat output of the heat source and a predetermined melting temperature of the annular sleeve is between about 0.02 and 0.05.

9. The wax warmer of claim 7, wherein the annular sleeve is distanced from the body of the wax warmer, the distance being measured from an exterior portion of the annular sleeve to an interior portion of the body.
