COMBINATION NIGHT LIGHT AND LIQUID VAPORIZER
Abstract
A combination night light and vaporizer for liquids in which a
plug-in electric wall bracket removably receives a throw-away
container in the form of a dispensing package containing the
vaporizable liquid. An electric lamp in the bracket provides a heat
source for vaporizing the liquid in the container as well as the
illumination for the night light, the lamp being controlled through
an energizing circuit which includes an electric flow path in the
vaporizable liquid between spaced electrodes built into the
container, and an overriding manually operable switch enables the
establishing of a circuit between the electrodes when there is no
liquid in the container and it is desired to energize the lamp for
use as a night light.

Description
PRIOR ART
In the prior art, there are numerous disclosures of electrically
energizable vaporizers, and also the concept of a combination night
light and vaporizer. The closest art known to applicant is the
following U.S. Pats.:

No. 3,248,530-Apr. 26, 1966
BACKGROUND OF THE INVENTION
The present invention relates generally to the field of electric
vaporizers.
It is heretofore been known from U.S. Pat. No. 2,612,432 to provide
an electric vaporizer container within which there is mounted an
electric heating element supplied with current through an electric
plug connector cord. The container is arranged to receive a
vaporizable material of cake form into heat transfer relation to
the heating element. This cake is molded around connection plug
terminals for completing a control circuit for the heating element
through a fusable link embedded in the cake, so that upon the
vaporization of a sufficient amount of the cake material, the fuse
will melt and shut off the heating element.
Applicant uses a different arrangement in that the vaporizable
liquid constitutes an electric flow path between internally
positioned electrodes normally immersed in the vaporizable
liquid.
It has also been known from U. S. Pat. No. 2,576,110 to provide a
steam vaporizer, wherein the current flow between a pair of spaced
electrodes immersed in a water well produces the steam for
vaporizing the medicament in a separate container, the electrodes
acting to terminate the heating, when the supply of water is
exhausted.
Here again, the electrodes do not operate in the same manner as in
applicant's device.
In the U. S. Pat. No. 2,611,068, it is known to provide a plug-in
type of vaporizer in which the prongs of the plug are pivotally
mounted for horizontal or vertical disposition. The structure
embodies relatively movable contacts, and thus differs from
applicant's unique arrangement in which the electric conductors are
directly connected to the plug prongs.
Applicant's present invention provides a unique departure from the
devices disclosed in the foregoing patented structures, and
embodies desirable features which are not present in the above
mentioned known structures.
SUMMARY OF THE INVENTION
The present invention relates generally to a combination night
light and liquid vaporizer of the plug-in type, and wherein the
vaporizable liquid is dispensed in a throwaway package
container.
It is one object to provide an improved combination night light and
vaporizer in which an electric lamp orovides both the night light
illumination and a heater for vaporizing the vaporizable liquid,
and wherein different night light color effects may be obtained by
using vaporizable liquids of different colors.
A further object is to provide a unique vaporizer combination which
includes a plug-in bracket arranged to removably receive a
throw-away self-contained dispensing package for a vaporizable
liquid, and which embodies means for automatically interrupting an
electric circuit for an associated heater lamp in the bracket, when
the vaporizable liquid is reduced to a predetermined amount.
It is also a further object to provide a vaporizer according the
foregoing object wherein an overriding control switch is provided
for connecting the heater lamp in circuit for use as a night light,
even though the vaporizable liquid has been reduced to the
predetermined minimum amount.
Another object is to provide an improved plug-in type vaporizer in
which the plug prongs are pivotally mounted for selective unitary
movements to horizontal and vertical orientation, and wherein the
electric conductors are connected directly to the prongs, thus
eliminating the use of sliding switch contacts.
Still another object is to provide as an article of manufacture a
throw-away dispensing container-package of unique construction for
vaporizable liquid, wherein the container has a bottom portion
arranged to provide a heat sink, and, which mounts plug-in
connection terminals for establishing a control circuit through the
vaporizable liquid between internal spaced electrodes.
Further objects of the invention will be brought out in the
following part of the specification, wherein detailed description
is for the purpose of fully disclosing the invention without
placing limitations thereon.

DESCRIPTION OF THE PREFERRED EMBODIMENT
For illustrative purposes, there is shown in FIG. 1 a combination
night light and liquid vaporizer according to the present
invention, which comprises a bracket structure "A" preferably of an
opague plastic material, and a container-dispenser "B" of an
appropriate clear or translucent plastic material.
As will be seen in FIG. 1, the bracket structure "A" is of a
generally L-configuration with leg portions 10 and 11 in right
angled relation. The legs are constructed respectively with
communicating internal cavities 12a and 12b to facilitate
electrical connections with the prongs 13 and 14 of a plug
connector 15 positioned at the outer end of the leg portion 10.
As thus arranged, the bracket structure can be plugged into a
conventional electrical receptacle, and thus supported in an
operative position. Since the prong receiving openings of
conventional receptacles are sometimes vertically arranged and
sometimes horizontally arranged, provision is made for pivotally
orienting the prongs of the plug connector to accomodate it for use
with either type of arrangement. For this purpose, the prongs 13
and 14 have their innermost ends mounted in a disc 16 of insulating
material, this disc being rotatably supported within a recess 17
upon a retaining screw 18 which also provides the pivot for the
disc. As best shown in FIG. 6, the disc 16 is peripherally provided
with an arcuate groove 19 which receives a fixed stop pin 20. As
thus arranged, the disc may be rotated through an angle of
90.degree. so as to properly orient the prongs of the plug
connector.
In order to eliminate the use of sliding contacts as conventionally
embodied in structures of this character, electric conductors, as
shown at 21 and 22 are connected directly to the inner ends of the
prongs 13 and 14. It will be noted that the conductors 21 and 22
are carried through the internal cavity 12a and are so positioned
therein that during rotative movements of the disc 16 in opposite
directions, the conductors 21 and 22 are free to shift
longitudinally without being subjected to damaging bending forces.
As shown in FIG. 2, the lower end portion of the conductors 21 and
22 are preferably coiled as indicated at 21a and 22a. As thus
arranged, the inherent disadvantages of sliding contacts will be
obviated.
As shown in FIG. 2, the leg portion 11 is fabricated to provide a
recess 23 which has its uppermost end opening into a top surface 24
of the leg portion 11. This recess mountingly receives therein a
lamp socket 25 adapted to removably receive an electric lamp 26
which projects above the top surface 24 so as to provide
illumination for the night light and form a heater for vaporizing
the liquid within the associated container-dispenser "B."
Diamatrically positioned on opposite sides of the recess 23 are
upwardly opening recesses 27--27 for respectively mountingly
receiving therein appropriate female type contacts 28--28.
The container-dispenser "B" is constructed as a throwaway
dispensing container which may be filled with a vaporizable liquid
such as a deodorizer, medicinal inhalant, humidifier, etc. As will
be best seen in FIG. 2, the container is of generally cylindrical
configuration and is fabricated with a thick base portion 29 which
effectively provides a heat sink at one end of an internal cavity
30, and at its other end is provided with a perforated end wall 31
having openings 32 therein. The openings are normally sealed at
their outermost ends by means of a sealing disc member 33 of
suitable plastic, rubber or other material. The disc member is
normally retained in a sealing position by means of a removable cap
member 34 which may be of conventional construction and may be of
the snap-in type.
The base portion 29 mounts a pair of spaced elongate electrodes
35--35 which project above the base portion 29 into the cavity 30.
It will be observed that the projecting portions of the electrodes
are surrounded by the material of the container, except for the
exposed tip portions as indicated at 35a.
The lowermost ends of the electrodes 35--35 are respectively
provided with projecting end portions which form male plug
connectors 36--36 which are adapted to mate with the female
contacts 28--28 in the mounted position of the container-dispenser
"B."
The base portion 29 is formed with a recess 37 which is positioned
between the electrodes 35--35 and has an end opening into a surface
38 having confronting relationship with the surface 24, when the
container-dispenser "B" is mounted on the bracket. The recess 37 is
arranged to register with the recess 23 so as to operatively
receive the electric lamp 26 therein into illumination transmitting
relation as well as heat transfer relation to the base portion
29.
It has been found desirable to provide ventilation for the recess
37, when the container-dispenser "B" is operably associated with
the bracket structure "A." For such purpose, as shown in FIG. 3,
there is provided in the surface 38 of the container-dispenser a
radially extending groove 39 which has its innermost end in
communication with the recess 37, and its outermost end in
communication with ambient atmosphere.
Electricity is supplied to the electric lamp 26 through an
energizing circuit as follows: from prong 13 through conductor 21
to one of the lamp terminals, from the other lamp terminal through
a conductor 40 to one of the female contacts 28 and associated male
plug 36 to an electrode 35; from this electrode through the
vaporizable liquid to the other electrode 35, associated male plug
36 and female contact 28; thence through conductor 22 back to the
plug prong 14.
By utilizing the vaporizable liquid to provide a link in the
energizing circuit between the electrode tips 35a--35a, it will be
apparent that the lamp 26 will be energized so long as a flow path
exists in the vaporizable liquid between the tips of the
electrodes. However, as soon as the level of the vaporizable liquid
is reduced to an amount in which the liquid level is between the
insulated portions around the electrodes, the circuit to the lamp
will be terminated and automatically cut off. Upon the insertion of
a filled container-dispenser "B," the circuit will again be
established so that the unit will continue to operate as a
vaporizer. It will of course naturally follow that when a new
container is connected to the bracket, the cap 34 should be removed
along with the sealing disc 33 in order to permit the vaporized
liquid to be disseminated through the openings 32 into the
surrounding atmosphere.
It will be appreciated that there may be times when it is desired
to utilize the device as a night light, when there is an
insufficient amount of liquid in the container-dispenser "B" to
establish an energizing circuit between the electrode tips 35a-35a.
In order to provide for this situation, an electric switch 41 may
be optionally provided, this switch having its terminals connected
between the female contacts 28--28. Normally, the switch 41 would
be in an open circuit position during dependence upon the automatic
control by the electrodes, but in closed position the switch will
operate to establish a circuit between the electrodes independently
of the vaporizable liquid.
From the foregoing description and drawings, it will be clearly
evident that the delineated objects and features of the invention
will be accomplished.
Various modifications may suggest themselves to those skilled in
the art without departing from the spirit of my invention, and
hence, I do not wish to be restricted to the specific form shown or
uses mentioned, except to the extent indicated in the appended
claims.
