Definitions
- the present invention refers to an electric device for emanating electro-conductive substances, particularly substances comprising perfumed compositions in order to perfume the surrounding atmosphere, or insecticide substances, disinfectants, etc.
- perfumes at home highly increases when a house is occupied days and nights. Perfumes adjust smells coming from kitchen, pet beds and other sources of unpleasant odours. For this reason, perfumes and their diffusing devices are more and more searched for in order to create a pleasant environment.
- Devices for emanating substances are generally devices that use resistances to heat wicks made of porous material, that is both thermoplastic and thermosetting, or ceramic material, which wicks, immersed into a deodorising substance, get impregnated by capillarity; alternatively, resistances are used that supply blocks of porous material drenched with deodorising fragrances, as disclosed for example in document US-A-5, 574, 821.
- PTC thermistors are non-linear resistors, built with semiconductor materials, whose resistive value depends on the temperature: both on the ambient temperature, and on the temperature increase produced by dissipating power in the thermistor itself. They are manufactured by sintering various mixtures of oxides of materials such as iron, chrome, manganese, cobalt and nickel. At their pure state, these oxides have a high resistivity: however, they can be transformed into semiconductor materials by adding small amounts of a metal with different valence. Thermistors are used as temperature sensors or as stabilising elements and are characterised by a positive temperature coefficient; it must however be underlined that this is valid only within a certain temperature range.
- Object of the present invention is thereby creating a device for emanating electro-conductive substances which can be easily manufactured, have low production costs and a high degree of reliability and performance.
- the device of the invention that provides a tank containing the substance to be vaporised, two electrodes in contact with a support made of plastic material such as sintered polyethylene, felt or the like, of an electrode-protecting cover in which a diffuser stack can be embedded and a frame with structural functions, in which the supply plug to be connected to household mains can be buried, through co-stamping.
- the operating principle is based on the characteristic of ionic conductor provided by the solution, that, containing ions in a small concentration, is an electrolytic solution.
- the resistivity (or inversely the conductivity) of such solution depends on ion concentration and, when it is crossed by electric current, it is heated due to Joule effects.
- the produced heat is RI 2 , where R is the resistance of the solution included between the electrodes and I is the current intensity. Heating of the perfumed solution makes all volatile components evaporate.
- Electrodes In fact, if in a solution of electrolytes (salts, alkaline hydroxides) , commonly called “II species conductors" (or ionic conductors), two metal foils are immersed and an electromotive force, or difference of potential, is imposed upon them, there is a passage of current between the two foils called electrodes.
- electrolytes salts, alkaline hydroxides
- II species conductors or ionic conductors
- a further advantage consists in using, as deodorising solution, mainly substances with a high water percentage with the addition of a suitable electrolyte and aromatising elements, differently from currently-marketed vaporising devices that use costly solutions, coupling suitable fragrances with natural or synthetic oils such as aldehydes, ketones, esters or terpenes, as disclosed in documents US-A- 4,411,829 and US-A-4, 434, 306, or pesticide volatile substances such as p-dichlorobenzene, or terapeutic substances such as menthol.
- Solvents in percentages ranging between 20% and 50%.
- the emanating device of the invention instead advantageously exploits the electro-conductive properties of this substance, implying a high cost reduction in realising the solution to be vaporised.
- the emanating device could be equipped with a suitable supply voltage adjusting system or with a mechanical system that makes the electrodes approach or go away one from the other, in order to be able to easily modify the amount of substance to be delivered in time.
- the container can be of the interchangeable type, and for such purpose it could be equipped with suitable anti-filling valves, in order to prevent the consumer from filling-in the container itself with a liquid that not only is inadequate for the operations, but is also potentially dangerous.
- Figure 1 is a perspective view of the device of the present invention connected to household mains;
- Figure 2 is an exploded view of the device of the invention
- Figure 3 is a cross view of the device of the invention.
- Figure 4 is a detail of the support in contact with the electrodes .
- the Figures show a currently-preferred, but non-limiting, embodiment of the device 1 for emanating electro-conductive substances 10 of the invention. In the description, all percentages of components are assumed in weight unless otherwise specified.
- the device 1 of the invention substantially comprises: a support frame 8; at least one tank 2 containing the substance 10 to be emanated, connected to the support frame 8; and at least two electrodes 6 supplied by supplying means 12 such as for example a common electric plug to be connected to the mains outlet 18 (for example at 220 V a.c.) in a wall 19 (as can be seen from the operating view in Fig. 1) .
- the electrodes 6, as can be seen, are adapted to generate heat in order to vaporise the substance 10 in the environment and are simultaneously adapted to stop the heating current flow when the substance 10 has been completely vaporised.
- the electrodes 6 are placed outside the tank 2, so that the level of substance 10 does not affect in any way the conduction behaviour.
- the device 1 of the invention comprises at least one terminal board 7 housed in the support frame 8 and that is in contact with the electrodes 6 screwed thereon.
- the terminal board 7 is thereby adapted to perform the electric connection of the electrodes 6 through the electro- conductive substance 10 with which it is drenched (if of a suitable material) , or through which the substance 10 passes, if allowed by the arrangement of the terminal board 7 itself.
- the device 1 finally comprises at least one unit 11 connected to the tank 2 and that simultaneously performs multiple functions, the first one of which, as previously seen, is being a protective cover for the electrodes 6. Moreover, the unit 11 is equipped with support means 20 for the tank 2, with delivering means 22 for the substance 10 and with diffusing means 3 of the substance 10 in the environment, thereby allowing to realise a device 1 with a compact configuration through a very simple and efficient multifunctional arrangement.
- Fig. 2 shows an exploded view of the emanating device 1 of the present invention which points out the internal device construction.
- the containing tank 2 obtained by blowing will preferably be realised in a transparent material, in order to point out the product level.
- a transparent material in order to point out the product level.
- the currently-preferred materials that can be employed the following can be cited: glass, polypropylene, polyethylene terephtalate, or the like.
- the device 1 will be again operating by using the containing tank 2 in its "refill” version: in such version, the tank 2 will be suitable sealed with a peelable film 28, impermeable to vapours.
- This impermeable film 28 could be a sheet of aluminium, polypropylene or other materials that are particularly adapted for this type of application, hot- or ultrasound-, welded.
- the container will be pressure-engaged in the unit 11 by placing the mouth 24 of the containing tank 2 into the opening 22 whose walls have the function of channelling the substance 10 flow.
- the possible protection film 28 will be pierced by the projection 26 that extends upwards in a coaxial way from the opening 22.
- the unit 11 due to the way in which it is made, also operates as dispensing device for the substance 10 on the terminal board 7 in which the electrodes 6 are located, that are placed under the diffusing means 3, preferably composed of a diffusing stack 3.
- the diffusing stack 3 is suitably shaped as a frustum of cone, with its greater surface oriented towards the terminal board 7, in order to convey the evaporation products towards the outside.
- the diffusing stack 3 is equipped, at its end with smaller diameter from which the substance 10 goes out towards the environment, with at least one, and preferably two or more projections 30 adapted to make the exiting substance 10 move on a zig-zag path before its diffusion.
- the material for the terminal board 7 must have certain characteristics, taking into account that the absorption of the substance 10 must occur in relatively short times, but at the same time an excessive absorption could make the substance itself go out.
- felt or a plastic porous material must be pointed out with pore sizes approximately varying between 50 and 60 microns.
- the liquid solution 10 can be taken in contact with the terminal board 7 through the action of a plate made of plastic material whose surface is grooved.
- the grooves in fact, operate as capillary vases along which the liquid substance 10 flows.
- the thereby- manufactured unit will be housed inside the frame 8.
- the frame 8 is typically realised in injection-moulded plastics, such as polypropylene, polyamide or the like.
- plastics such as polypropylene, polyamide or the like.
- the frame 8 and the conductor elements 9 of the plug 12 can be moulded together integrally.
- the elements 9 can be made of plastics with metal inserts (not shown) in order to conduct electric current .
- the preferable location of the electrodes 6 is shown in Fig. 3, since the electrode 6 surface exposed to substance vaporisation is minimum, thereby removing all problems linked to the electrode 6 oxidation due to vaporisation products .
- the preferable distance of the electrodes 6, as shown in Fig. 4, is about 1 cm, but a good product vaporisation can be obtained also with longer distances, between 2 and 3.5 cm.
- the electrodes 6 will obviously be hidden by an adequate protection (not shown) in order to avoid accidental contacts when operating the emanating device 1.
- the emanating device 1 can suitably be moulded in different shapes, including the rounded one being shown, with a diameter of about 76 mm and a length of 70 mm.
- This chance of realising a compact and pleasing external shape is an ornamental effect caused by the functional structure of the inventive device 1: this is a further advantage of the invention, since, in time, a design change when devising devices of this type has now occurred. Not many years ago, these products were devised only from the functional point of view, since their purpose was covering or masking unpleasant odours.
- the devices of the environment deodorant type are designed also in order to embellish and decorate the house.
- the operation of the device 1 of the invention is as follows: by connecting the plug 12 to the supply, the device 1 is operated when the liquid solution 10 is absorbed by the terminal board 7 through the opening 22, and the circuit closure is thereby caused. When this occurs, the passage of current into the electrolyte starts and creates a temperature increase up to values varying from 60 °C to 70 °C. The maximum temperature values are reached in a relatively short interval of time (on the order of 1 minute) . In this interval of time the temperature increases in an approximately constant way. It has been detected that, under the above-described conditions, using a vessel whose capacity is 50 ml, the device autonomy is about 12 continuous hours.
- the conductivity of the water-based substance can vary between 63 and 273 us.
- the electro-conductive substance 10 is obtained very simply by adding to distilled water about 0.1% of sodium sulphate and, according to the device mode of use, perfumed fragrances, pesticides, disinfectants, etc.
- This type of emanating device 1 is particularly interesting due to its simplicity, since it has a reduced number of pieces, uses inexpensive plastic materials and does not need sophisticated adjustments by the consumer. In the meantime, the device 1 of the invention is distinguished by a constant dispensing of the solution, during the whole life span of the product.
- the device 1 with reference to the Figures and the description can be, by making modifications and variations (for example the electrodes could be, in a further arrangement not shown, be advantageously housed in the tank part of the device 1, thereby keeping the efficiency of the device 1 itself constant in time) , satisfy for a skilled person in the art particular and specific needs, all however included within the scope of the invention, as defined by the following Claims.
- the device 1 of the invention can be operatively placed in a position in which the tank 2 is located above the electrodes 6 and the terminal board 7 with respect to the ground: in this way, the electro-conductive substance 10 is transported onto the terminal board 7 by its own weight through gravity.
