Abstract

Abstract A heating device included a body having a seat for the positioning of at least one heating support having inserted therein at least one electrical resistive element, the resistive element being electrically connected to the pins of a plug for insertion into an electric socket. The body is provided with a first slit for the positioning of a first small plate or tablet, containing evaporable substances (such as antifly and antimosquito substances), so as to bring it in contact with at least a portion of the heating support and cause the evaporation of the substances in the tablet at a high temperature (about 140° C.). A further seat is also provided spaced from the heating support, in which a support is arranged for a second tablet (for example, containing deodorizing substances), which evaporate at a not unduly high temperature (about 70° C.). The body provides apertures for the passage and diffusion of the evaporated substances. Additionally, the plug pins are arranged on a support adapted to rotate through a 90 degree arc, so that the tablet can be inserted always in a horizontal position, regardless of orientation of the holes of the electric socket.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 131 words
A heating device for tablets containing substances evaporable at different temperatures, including a body provided with a pin support, a plurality of electric plug pins mounted to said pin support and adapted to be inserted in a voltage socket, and with a first seat for positioning of at least one heating support of insulating material, in which at least one electrical heating element is positioned, the ends of which are connected respectively to the pins, said body being provided with at least one slit for the positioning of an evaporable tablet at a first distance from said heating element, and comprising means for providing at least one additional seat for the positioning of at least one further tablet at a second distance from said heating element greater than said first distance.
Claim 2
Dependent Claim 131 words
A heating device for tablets containing substances evaporable at different temperatures, including a body provided with a pin support, a plurality of electric plug pins mounted to said pin support and adapted to be inserted in a voltage socket, and with a first seat for positioning of at least one heating support of insulating material, in which at least one electrical heating element is positioned, the ends of which are connected respectively to the pins, said body being provided with at least one slit for the positioning of an evaporable tablet at a first distance from said heating element, and comprising means for providing at least one additional seat for the positioning of at least one further tablet at a second distance from said heating element greater than said first distance.
Claim 3
Dependent Claim 50 words
A device according to claim 1, wherein said means for providing at least one additional seat are arranged at a predetermined spacing relative to the heating support to obtain a temperature at said first seat about 70 degrees C. greater than a temperature at said at least one additional seat.
Claim 4
Dependent Claim 24 words
A device according to claim 1, wherein said additional seat has arranged therein an additional plane for supporting said at least one further tablet.
Claim 5
Dependent Claim 26 words
A device according to claim 1, wherein at the tablet seats, apertures are provided on the body for the passage of vapor from said evaporable tablet.
Claim 6
Dependent Claim 30 words
A device according to claim 1, wherein said body comprises at least two body parts engaging with said pin support, said two body parts being freely rotatable around said support.
Claim 7
Dependent Claim 39 words
A device according to claim 4, wherein said at least one additional seat for the positioning of at least one further tablet is provided with apertures for the passage of heat being transmitted by convection from said heating element.
Claim 8
Dependent Claim 25 words
A device according to claim 5, wherein stop elements are provided for preventing said two body parts from rotating through an angle exceeding 90 degrees.
