Abstract

A device for treatment of air in a room or other space in which the air is perfumed, or deodorized, or purified. A solid refractory material acts as a carrier for air-treatment material thereon which is gasified upon heating of the carrier material. The solid carrier material is held in a casing within which an electrically energized heating element, preferably in the form of a lamp, heats the refractory material and the air-treatment material is liberated to effect the air treatment. The lamp also serves as an indicator light to show whether or not the device is energized.

IIIIIIIIIHHI I u III II II 2 AIR TREATMENT DEVICE CROSS REFERENCE TO RELATED APPLICATIONS The present invention relates to an air treatment device of the type described in my co-pending application Ser. No. 292,308 filed Sept. 26, 1972.
BACKGROUND OF THE INVENTION The present invention relates to dispensers and more particularly to an air-treatment device for perfuming, purifying and/or deodorizing the air within a space.
DESCRIPTION OF PRIOR ART Air perfuming devices and dispensers are well known. Many of these devices simply hold a vaporizable liquid for treatment of the air or a solid material that is sublimated. Generally these devices are limited to treatment of the air in relatively small confined space. Y
SUMMARY OF THE INVENTION A general purpose of the present invention is to provide an aim-treatment device that can be constructed as a small unit for small spaces and constructed as a large unit for use in large open spaces, for example factories and the like.
Another object of the invention is to provide an airtreatment device or dispenser in which heat is used for carrying out the gasification of an air-treatment material which is liberated from a solid carrier material which is unchanged by the application of heat.
The dispenser and air-treatment device according to the invention comprises a tubular casing within which is defined at least one space adjacent one end of the casing which is in communication with the atmosphere and the interior of the casing. Within this space is held a solid carrier material which is treated with a gasifiable material which is driven off from the carrier material by the application of heat to the space and carrier material therein.
Within the casing a heating element, formed by a lamp of an appropriate voltage, is located and connections are provided to switch it to a power source exterior to the container. The casing also has a window with a transparent cap that will be illuminated when the lamp lights to act as a pilot light.
BRIEF DESCRIPTION OF THE DRAWINGS Other objects and advantages of the air-treatment device in accordance with the invention will appear from the following description of an example of the invention, and the novel features will be particularly pointed out in the appended claims and drawings in which:
FIG. 1 is an elevation view of an air-treatment device according to the invention; and
FIG. 2 is a cross-section of the air-treatment device in FIG. 1.
DESCRIPTION OF THE PREFERRED EMBODIMENTS As illustrated in the drawings an air-treatment device according to the invention comprises a tubular casing l which is made of a suitable material, such as metal or plastic. The casing is provided at opposite ends with removable end covers 2 having a grate, 3 with openings 20 therein. The end covers are provided with an annular shoulder 22 by which they can be slidably and snuggly fitted into the tubular casing 1.
Within the casing 1 washer-like elements 4 are mounted. Each element 4 has a central opening providing communication between the central interior area of the casing 1 and its end spaces adjacent the grates 3. Each of the elements 4 is provided with a plurality of projections I2 spaced from each other and facing toward the respective grate 3. The projections 12 fit into openings 13 in a solid cake of carrier material 15 to snugly hold the material within the respective end spaces between an element 4 and a grate 3.
The solid carrier material 15 is provided with gasifiable air-treatment material thereon that is capable of treatment of the air when the carrier material 15 is subjected to heat, for example when the space within is heated. The material 15 is solid refractory material containing, for example, perfume oil or essence which is more readily liberated when the cake of material is heated.
The heating element formed by the lamp 5 is located between washers 7 and supplied power through the terminals, 8, 9 which are connected to the corresponding power source not shown.
To enable a user check the device to ensure that the unit is electrically activated, a transparent plastic cap 6 is provided in the casing through which it can be seen if the lamp 5 is energized or on the contrary if it is off and the treatmentdevice not being heated. As can be seen, the lamp 5 serves the dual function of both heating the air treatment material and also providing an indication of whether or not the device is electrically energized.
What is claimed is:
1. An air treatment device for perfuming, deodorizing and purifying air comprising, a tubular casing, grate means at each end of said casing providing communication between the interior of said casing and the atmosphere, a respective holding means axially spaced from each said grate means, a cake of solid carrier material carrying thereon a heat activated gasifiable, air-treatment material mounted on each said holding means adjacent a said grate means, an electrically activated lamp within said casing adjacent said cakes of carrier material to heat said carrier material and liberate the treatment material therein which passes through the respective grate means to the area adjacent the casing, means for connecting said lamp to an electrical power source, and means in said casing through which the lamp is viewable to determine if the device is energized.
2. An air treatment device according to claim 1 in which each said holding means comprises a washer-like element having a central opening, a portion of said lamp located adjacent said holding means.
3. A device as in claim 1 wherein said means for viewing the lamp comprises a circular cap of transparent plastic material in a wall of said casing.
