Abstract:
A nebulising element (1) for liquid substances, which can be coupled to procurement means (5), such as porous elements impregnated with the liquid to be diffused for example. It includes at least one membrane (9) with a microperforated area (11); at least one piezoelectric element (10) connected to an electronic circuit (20) and coupled to the membrane (9) to cause it to vibrate; at least one first (6) and one second (7) support that can be placed on top of one another and create, on their interior a compartment (8) to contain the membrane (9), the piezoelectric element (10), and a space of limited dimension for the liquid to be nebulised, created beneath the membrane (9). The second support (7) has an opening (12) for the nebulised liquid outlet, located in correspondence with the perforated area (11) of the membrane (9). The nebulising element (1) also includes at least one collector (13) for. the liquid that flows from the porous element (5) to the collector (13) itself by capillary action; at least one capillary opening (14) to allow in the liquid to be nebulised and at least one outlet opening (15) to aid air circulation.
Abstract:
The invention refers to a spray pump device for spraying a liquid operated by a memory shape element (11). The spraying device is provided with a memory shape alloy wire (11) with electrical resistivity, that is able to generate heat that increases its temperature so that due to memory shape property, the wire shrinks when current is applied. This shrinking permits the wire to activate a pump that atomizes a volatile substance.
Abstract:
The invention refers to an electrical heating evaporator for evaporating active substances such as perfumes and/or insecticides, in which the means for regulating the evaporation rate comprises an electrical heater resistor for which the power supplied is regulated through a potentiometer constructed on a printed circuit board. The evaporation rate can be adjusted for a wide variety of types of chemical substances, without the need of substantially modifying the design of the device.
Abstract:
The invention refers to a container (1) for volatile substances having a first chamber (2) containing a porous material (4) impregnated with a first volatile substance, and a second chamber (3) containing a second volatile substance. The evaporation of the first and the second volatile substances is synchronized so that both volatile substances are finished substantially at the same time. The second volatile substance is used as a visual indication of the end of life of the first substance. The open base of the first and the second chamber are covered by a permeable film. The container may be arranged with a heater for the volatile substances.

Abstract:
A method of delivering a volatile material to the atmosphere in a continuous manner is disclosed. The method includes providing a delivery engine having a reservoir that includes a volatile material mixture. The volatile material mixture includes about 40% to about 100%, by total weight, of the volatile materials each having a vapor pressure at 25°C of less than about 0.1 torr. The delivery system also includes a microporous membrane enclosing the reservoir, wherein the microporous membrane comprises an average pore size of about 0.01 to about 0.03 microns.
Abstract:
An apparatus for delivering a volatile material in a continuous manner is disclosed. The apparatus includes a delivery engine having a reservoir for containing a volatile material; a rupturable substrate secured to the reservoir; a rupture element positioned adjacent to the rupturable substrate; and a breathable membrane enclosing the reservoir, rupturable substrate and rupture element. In some embodiments, the apparatus includes a housing having a notch for compressing the rupture element and breaching the rupturable substrate as it is inserted into the housing.
Abstract:
The invention refers to a device for evaporating volatile substances comprising: a container of a liquid volatile substance, and a vapour permeable membrane (1) and a thermoplastic porous or fibrous laminate (2) bonded together. Said container is closed at its opening by said vapour permeable membrane (1) and the fibrous laminate (2), wherein the fibrous laminate (2) is welded to the thermoformed part of the container.
Abstract:
The present invention refers to an evaporator device (1) for volatile substances provided with a closure system that facilitates the replacement of the refill or container of the volatile substance. The invention provides a safety closure system (8) for the evaporator device, which makes difficult for children to get access to the tablet or container (5) of the volatile substance. A closure member (8) and a container are associated in such a manner that during the opening movement of the closure member, at least part of the container is extracted out of the chamber.
Abstract:
The present invention relates to an electric evaporator device of volatile substances with adjustable evaporation intensity. A heating plate (4) defines a first chamber (6) separated from a second chamber (8), wherein a heat generator (5) is located inside the first chamber (6). A regulation opening (13), located in the first chamber (6), allows the exit of a heated air flow from the first chamber to regulate the temperature both in the first chamber (6) and the heating plate (4), enabling thus the regulation of the evaporation rate.
