Definitions

• the invention relates to a heating device for tablets impregnated with active materials, to achieve their vaporization and their corresponding use as an air freshener or as an insect-killing medium.
• the device uses as a heating medium a PTC semiconductor tablet, known by these acronyms for being positive temperature coefficient tablets, in which the resistance increases exponentially with the temperature until it reaches the previously established, not allowing more current to pass through.
• a PTC semiconductor tablet known by these acronyms for being positive temperature coefficient tablets, in which the resistance increases exponentially with the temperature until it reaches the previously established, not allowing more current to pass through.
• the type of devices referred to They comprise two electrodes with their corresponding connection pins, as well as a concentric conduit through which the wick that is impregnated with the liquid that is intended to be vaporized is disposed, being among the aforementioned electrodes the heating pad itself, using as a transmitter housing of the ceramic material heat, so that this being a poor thermal conductor the heating of the pellet corresponding to the heat transmission is not efficient enough, that is to say that the consumption of active matter is not regular.
• the device that is recommended has been designed to solve this problem to full satisfaction, based on a simple and effective solution, since it uses PTC tablets as heating element, and is intended to heat tablets impregnated with liquid active materials.
• the device has the peculiarity that between the electrodes and the heat conducting material, determined by an aluminum plate or sheet, an insulating sheet of small thickness is provided, all mounted on a housing that can be materialized in plastic material.
• the heating of the tablet is guaranteed in a completely homogeneous way, along its entire surface.
• housing-support of the aluminum plate is materialized in plastic, preferably in polyamide, contrary to what occurs in known systems or devices where the support-housing of the thermally conductive material is ceramic.
• the heating device will have a longer duration, by virtue of the aforementioned characteristics, that is to say the housing being constructed in plastic and in being aluminum the thermal material used.
• the device includes the aforementioned plastic housing, with a prolonged central hole in a neck, as well as with means of positioning and retention by interlocking of the aluminum plate itself, being superimposed on the sheet of insulating material, covering the two electrodes between which the heating semiconductor tablet itself is located, with its corresponding connection terminals that are passed through windows or grooves provided at the bottom of the housing itself.
• Figure 1 shows a representation corresponding to an exploded view of the different components or parts that constitute the tablet heating device made in accordance with the object of the invention.
• Figure 2. Shows a side view, according to a longitudinal section, of the device of the invention.
• Figure 3. Shows a top plan view of the same heating device represented in the previous figures.
• the device of the invention is constituted from a general housing (1) with a rectangular contour, affected by longitudinal windows, while centrally it is provided with a hole (2) that extends into a neck (3) of considerable length, projected downwards as shown in Figure 2, the hole (2) being made in a circular recess (4) in which the circular electrode (5) is positioned with elastic pins (6) and a lateral extension (7) constituting the corresponding connecting pin, the latter being through a groove (8) provided in the bottom of the housing (1).
• a second slot (9) is provided for the passage of the pin (10) corresponding to the second electrode (11), this being of rectangular configuration with a small lateral fin (12) that fits into the recess (13), all of which being perfectly positioned the electrodes (5) and (11) referred to and among them the heating semiconductor tablet itself.
• the insulating paper sheet (15) is located on the electrode (11), and on it the aluminum plate (16), being perfectly embedded in the upper part of the housing (1), by retaining it by means of nails (17) provided for this purpose in corresponding elastic pins that the housing has at the ends of its side walls (18).
• the general structure of the device is simple and practical, since the housing is made of plastic, and the electrodes (5) and (11), and among them the heating pad (14), are perfectly positioned in the general housing (1) and covered the whole assembly by means of the aluminum plate (16), with the interposition of the sheet of insulating paper (15), which makes the device effective in its function, which is that heating the tablet (14) entails the vaporization of active substances contained in tablets.
