Description

Heater evaporator liquids

Object of the invention

The present invention relates to a liquid heater-evaporator, of the usually used as suppliers of a product air freshener, insecticide, disinfectant or similar, of which incorporate an electrical resistance capable of raising the temperature of the product in question, contained in a container, to facilitate its evaporation.

The object of the invention is to achieve a compact device in which the different integrating elements of the heating circuit are interconnected in the absence of cables, which greatly facilitates assembly and appliance maintenance.

Background of the invention

Within the wide range of solutions for contribution in the environment of an aromatic product, insecticide, medicinal, etc., a known and commonly used solution It consists of a small housing capable of receiving and fixing a bottle supplying the product in question, equipped with a wick, so that the sector of said emerging wick of the bottle is tightly attaches to a neck of the device, next to which in turn establishes an electric heating resistance, so that when the power circuit of the latter is closed, e] temperature increase in the free end of the wick remarkably favors the evaporation of the air freshener product that Such a wick goes. absorbing from the bottom of the jar.

These devices integrate a properly standardized plug, for connection to a plug base of the electrical supply network of the passenger compartment in which are located, have a switch in some cases of two and in others of three positions, sometimes they have a LED indicating its operating status, in sometimes they have a micro-swich that detects if it is a perfume or an insecticide, and also sometimes heating resistors are grouped into two sectors that can act independently or in combination to regulate the amount of heat contributed to the wick.

In short, these devices can reach perform seven differentiated functions in your application, by the incorporation of the aforementioned elements, and in the actuality for the electrical connection of said elements is they use electrical cables, which entangle the inside of the housing of the device, considerably complicate its assembly in processes of manufacturing and also hinder its subsequent maintenance, It is also necessary to use mechanical elements complementary to fix the switch, resistors, of the micro-swich, etc.

Description of the invention

The evaporator heater liquids that the invention proposes, allowing benefits equivalent to those of any conventional apparatus of the previously cited, from an operational point of view, being capable of performing the seven functions mentioned above, solves the problem fully satisfactorily previously exposed, constituting a simple and effective solution, of reduced volume, in which the different elements of the apparatus are perfectly interrelated both mechanically as electrically, allowing easy assembly of same.

To do this and more specifically, the heater-evaporator focuses its characteristics on the incorporation of a printed circuit board, preferably of fiberglass, in which all the components repeatedly cited, in the absence of cables, interconnected through the conductive tracks of said plate, which also constitutes the physical or mechanical support for such elements.

In this way and providing for the housing of the device a guide or suitable accommodation for implantation of the cited printed circuit board, with its components integrated in the same, it is enough to effect the closing of said housing so that the device is finished and in conditions of use, obviously prior connection of the printed circuit board to the device plug, or, where appropriate, to an external cable, topped off in the aforementioned plug, when a direct assembly of the device on a base is not foreseen plug

Description of the drawings

To complement the description that is being performing and in order to help a better understanding of the characteristics of the invention, according to a preferred example of practical realization of it, is accompanied as part member of that description, a set of drawings where with illustrative and non-limiting nature, what has been represented next:

Figure 1.- Shows, according to a view in perspective, the previously mentioned printed circuit board with the different operating elements integrated in it.

Figure 2.- Shows another perspective view of the set represented in the previous figure, by its face opposite to that of that figure.

Preferred Embodiment of the Invention

In view of the figures outlined you can be observed as the heater-evaporator that the invention proposes, from the use of a housing of any conventional type, focuses its characteristics on the incorporation of a printed circuit board (1), in which it establishes a hole (2) that in assembly situation results coaxial with the neck of the device housing intended to receive the wick of the bottle supplying the product in question, hole (2) surrounded by a plurality of heating resistors (3) that, as previously stated, they can work together or forming partial groupings, depending on the thermal level that the wick of the device must reach, and in function in turn of the type of product to be heated and evaporated.

On this same printed circuit board (1) it mount the circuit breaker main switch (4), a LED (5), a micro-swich (6) and any other type of electrical accessory that is necessary or convenient, all these elements being duly interconnected by the tracks (7) of the printed circuit board (1), located on the underside of it and visible in figure 2.

In this way the entire heating group of the device is integrated in one piece, specifically in the plate (1), in the absence of cables, allowing a pre-assembly that facilitates the final assembly of the device, since it is enough to connect the network connection cable with the pins (8) located on the underside of the plate (1), so that the circuit is in maintenance condition, definitively implanted in the device housing so that the hole (2) of the plate (1) faces coaxially to the wick receiver neck, and the switch (4) is facing a window that makes it accessible from the Exterior.

Claims (1)

1. Heater-evaporator of liquids, of the type of those that incorporate a heating resistance capable of raising the temperature of an air freshener, insecticide or similar product, containing a container carrying a wick on which evaporation occurs, characterized in that the different elements thereof corresponding to the heating circuit, that is to say the electrical resistors, the general switch, the micro-swich, the LED signaling diode and any other type of necessary or advisable component, are implanted on a printed circuit board, preferably of fiber of glass, which incorporates the conductive tracks for electrical connection between said elements and also acts as a physical support for them, said plate having a wide hole for passage of said wick and being conveniently shaped and dimensioned to inevitably engage inside the device housing, in the position where e The mentioned hole is coaxial to the wick and crossed by the latter, and in which its general switch is directly accessible from the outside through a window operatively practiced for that purpose.
