~3~Z~`35 TOILET DEODORIZER
This invention relates to new and useful improvements in deodorizing devices for toilets in order to extract air from the bowl of said toilet and discharge same after filtering through a charcoal filter, to the interior of the room.
Conventionally, such devices require remotely situated fans and a considerable amount of ducting to conduct the air from the toilet bowl to an external location such as into an attic or externally of the building.
This requires a relatively large fan and considerable ducting and as most of such devices are retrofitted, installation can be time consuming and expensive.
The present device is completely self-contained and utilizes an activated chaxcoal filter in order to remove the objectionable odor so that the air from the bowl can be discharged directly into the bathroom so that there is no plumbing, electrical or carpentry work involved in the simple installation of this product.
In accordance with one aspect of the invention there is provided a deodorizing device for a toilet having a toilet bowl which includes an upper rear side, a toilet seat with a rear portion and spaced apart fasteners hingedly securing the rear portion of the toilet seat to the upper rear side of the bowl, said deodorizer device comprising, in combination: an , .

DETAILED DESCRIPTION
Proceeding therefore to describe the invention ln detail, reference should flrst be made to Figures 1 and 2 ln which the device collectively deslgnated 10 comprlses a substantially planar panel 11 preferably made 13(~S~9~
of plastic and consisting of a lower planar plate 12 and an upper plate 13. These are secured together by screws 14 or the like so that the edges are sealed and the panels define a flat extractor and collecting chamber therebetween.
At the end of the lower plate 12, there is provided a container collectivelY designated 15 which includes an end wall 16, a base 17, and an upwardly and inwardly inclining sloping base wall 18 which joins the remainder of the lower plate 12 in a smooth curve as clearly shown in Figure 2.
An air entry slot 19 is provided in the front inwardly curved edges 20 of the upper and lower plates 13 and 12 and notches 20 are formed inwardly along the rear edqe in spaced apart relatlonship one upon each side of a cut away portion 21.
These notches engage over the screws or bolts 22 which normally secure the seat 23 of the toilet to the rear edge 24 of the bowl 25 for opening and closing hinging action as is conventional. Such seats normally include small bumpers on the lower surface ad~acent the front edge thereof to space the seat ~ust above the surface of the bowl and the bolts 22 are formed so that the spacing ls retalned at the rear side.
',' :, , ,',.. .. .
~3QSZ~5 This permits the planar panel assembly 10 to be engaged on the rear edge 24 of the seat with the notches engaging around the bolts 22 and the concave air intake slot 19 facing forwardly and following substantially, the contour of the rear side of the bowl.
When the seat is lowered in the usual manner, the planar panel is sandwiched therebetween with the container 15 being situated externally and slightly to one side of the side 26 of the bowl.
A fore and aft baffle 27 extends across the container between the end wall 16 thereof and adjacent the beginning of the upwardly and inwardly sloping wall 18 as clearly shown in Figure 2 and a circular aperture 28 is formed through this baffle as clearly shown.
A further baffle 29 extends between the end wall 16 and the baffle 27 and to one side of the contalner thus defining a battery carrier 30 into which a 9 volt DC battery 31 may be engaged.
A box like carrier 32 contains activated char-coal and is perforated on the front and rear faces, the rear face 33 only being shown in the drawings.
Thi8 slldes into the remainder of the container wlth the apertures 34 in the filter being situated in a discharge aperture 35 within the end wall 16 defined by -" ~3~5Z9~
the two vertical edges 36 of a cut-away portion as clearly shown.
A small electric fan 37 is supported on the inboard side of the baffle 27 adjacent the aperture 28 and is operatively connected to the battery by means of a connector 38 via a microswitch 39 which extends through the upper surface of the upper plate of the planar panel and is contacted by the underside of the seat 23 when the seat is lowered.
It ls positioned so that when the seat is lowered, the switch is not activated but when a predeter-mined pressure is applied to the seat from the upper side thereof, the microswitch actuates and operatively connects the battery 31 with the fan unit 37. The circuit is shown schematlcally ln Flgure 5.
In operation, actlvatlon of the unit is by pressure on the microswitch 39 which operates the fan whlch then draws alr from the bowl, through the intake slot 19 and into the lnterior of the planar panel, the plates of whlch deflne an extractlng and collectlng portion of the device. The fan forces the alr through the activated charcoal filter thus extractlng any odor and dlscharges same through the dlscharge 35 retainlng any odor causlng elements wlthin the fllter.
~3(~S295 Since various modifications can be made in my invention as hereinabove described, and many apparently widely different embodiments of same made within the spirit and scope of the claims without departing from such spirit and scope, it is intended that all matter contained in the accompanying specification shall be interpreted .as illustrative only and not in a limiting sense.
