Abstract

An assembly comprising a plug and a heating element. The plug comprises a body in which conducting poles are mounted for connection to an electrical socket, and the heating resistance comprises a body in which at least one electrical heating element, connected by means of electrical wires to the poles of the plug, the body of the heating element having a housing to receive a wick impregnated with volatile substances. At least one bridge connects the body of the plug to the body of the heating element, so as to avoid relative translation of the body of the plug with respect to the body of the heating element. The bridge has a breakable weakened part.

Claims (16)

1. An assembly comprising a plug and a heating element for a diffuser device for volatile substances, wherein

the plug comprises a body in which conducting poles for connection to an electrical socket are mounted, and

the heating element comprises a body in which at least one electrical heating resistance connected by electrical wires to the poles of the plug is disposed and said body of the heating element is destined to be disposed near to or in contact with a support impregnated with volatile substances to be diffused,

characterized in that the assembly further comprises

at least one connector having a first end attached to said body of the plug and a second end attached to said body of the heating element, said connector configured with a breakable weakened part, so as to avoid relative movement of said body of the plug with respect to said body of the heating element until the weakened part is broken, which causes the body of the plug and the heating element to no longer be connected through the connector.

2. The assembly of claim 1 , wherein the body of said plug has a rear circular flange able to engage rotatably with an outer shell of the diffusing device.

3. The assembly of claim 1 , wherein said second end of said connector is integral with the body of the heating element.

4. The assembly of claim 1 , wherein said first end of said connector is integral with the body of the plug and said second end of said connector is integral with the body of the heating element to prevent any relative movement of said heating element with respect to said plug.

5. The assembly of claim 4 , wherein the connector is substantially L-shaped and the breakable weakened part is disposed at the elbow of the “L”.

6. The assembly of claim 4 , wherein the connector has ribs disposed in proximity to the heating element body and to the plug body.

7. An assembly comprising a plug and a heating element for a diffuser device for volatile substances, wherein:

the plug comprises a body in which conducting poles for connection to an electrical socket are mounted;

the heating element comprises a body in which at least one electrical heating resistance connected by electrical wires to the poles of the plug is disposed and the body of the heating element is destined to be disposed near to or in contact with a support impregnated with volatile substances to be diffused;

at least one connector having a first end connected to the body of the plug and a second end connected to the body of the heating element, wherein the connector prevents relative movement of said body of the plug with respect to said body of the heating element; and

the connector configured with a breakable weakened part so that, upon breaking the weakened part, the body of the plug is no longer connected to the body of the heating element by the connector and becomes moveable relative to the body of the heating element.

8. The assembly of claim 7 , wherein the body of the plug has a rear circular flange configured to engage rotatably with an outer shell of the diffuser device when the weakened part becomes broken.
