BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a deodorizing device for toilet bowls, and more specifically to a deodorizing device that is automatically triggered. [0003] 2. Description of the Related Art [0004] The problem of deodorizing bathrooms and toilet bowls due to odors from a bowel movement has long existed. One solution is simply to manually spray deodorizer in the bathroom. Another solution is to keep deodorizing that works all the time in the bathroom. [0005] Other solutions have been created that are intended to automatically deodorize in response to some event connected to going to the bathroom. For example, U.S. Patent Publication No. 2004/0064884 to Egeresi teaches a toilet odor blocking system which applies soapy water and foam or chemical spray into the bowl upon the user's sitting on the toilet seat to block any odors from emanating from any waste. The bubbles for covering the human waste are guided through an embedded hose in the toilet seat. [0006] U.S. Pat. No. 6,029,286 to Funk discloses an apparatus for manually delivering an odor reducing chemical to a toilet bowl comprising a remotely located pressurized source of odor reducing chemical, a valve communicatively connected to the pressurized source of odor reducing chemicals for selectively releasing odor reducing chemical from the pressurized source, a button located at a location remote from said pressurized source of odor reducing chemical for opening said valve when activated by a user, where the activating mechanism may be selectively activated one or more times by the user either before, after or while the user is seated. The device has a bracket for mounting on a toilet, and a spray nozzle. [0007] U.S. Pat. No. 6,387,321 to McGill discloses a process for controlling toilet odors by use of compositions comprising a hypochlorite compound and a hydrogen peroxide compound. The compositions are useful for preventing, reducing and/or eliminating the odor emitting capacity of human or animal excrement in an aqueous solution. A conventional liquid-dispensing mechanism may be configured to automatically dispense an odor-reducing, -preventing or -eliminating amount of the active ingredients when a user sits on the seat of the toilet. [0008] U.S. Pat. No. 5,862,532 to Cain discloses a dispenser which fails to automatically dispense the deodorant, and instead requires the user to press a knob to spray the freshener into the toilet bowl. This invention is not practical for the fact that user can instead press the knob of the spray can and spray the deodorant into the bowl. Furthermore, Cain's invention has a very unhygienic way of delivering the spray mist into the bowl through a head placed on the bowl where it will accumulate with liquid and solid waste. [0009] U.S. patent application Ser. No. 20040266638 to Requejo et al. discloses compositions and methods designed to manage toilet odor which comprise a fragrance and other compounds for reacting with substances that cause toilet malodor. Compositions are in a package and may be dispensed into conventional toilets, either before, during or after use U.S. Pat. No. 5,383,237 to Baker discloses a new and improved toilet seat deodorizer apparatus which includes a flexible, resilient air pump assembly shaped substantially in the form of a toilet seat, a connector assembly for connecting the air pump assembly to a toilet bowl, and an odor dispenser assembly connected to the air pump assembly. The odor dispenser assembly includes a first screened end in direct communication with air contained within the flexible, resilient air pump assembly and includes a second screened end in direct communication with air which is outside the air pump assembly and the odor dispenser assembly. When a person sits upon the flexible, resilient air pump assembly, a quantity of air is pumped from inside the air pump assembly, through the odor dispenser assembly, to outside the odor dispenser assembly to room air in the room in which the toilet is located. [0010] U.S. Pat. No. 5,307,525 to O'Brien teaches adding a few drops of an appropriate fluid mixture, such as a chlorinated hydrocarbon containing a small amount of a volatile fragrant fluid, to water in a toilet bowl prior to the use of the toilet. A unique property of the first fluid causes the resultant mixture to spread quickly over the entire surface of the water, forming a nonpermeable film across which the odor emanating from unflushed feces cannot pass. The second fluid quickly vaporizes from this film allowing the resulting concentrated fragrance to neutralize within the toilet bowl the flatulence odor produced during a bowel movement. A person sitting upon the toilet seat actuates a semiautomatic fluid dispenser. [0011] U.S. Pat. No. 6,785,912 to Julio discloses a toilet seat with a mechanism to send ions into the bowl. [0012] What is needed is a spray that is automatic, compact, does not involve blowing air or power sources, does not offend the user, and acts at the source of the problem. Such a device should also be easy to mount, nonobtrusive, and spray only a desired amount. SUMMARY OF THE INVENTION [0013] In one embodiment, there is a deodorizing and/or disinfecting spray device actuated by sitting on a toilet seat, which sprays deodorizing chemicals into the bowl. A mounting structure with a resilient actuator arm activates the spray when the user sits. [0014] In a preferred embodiment, the device has a housing with a lower portion having an inverted U-shape to fit over a standard rim of a toilet bowl, a compact spray container mounted on the housing, an upper actuating lever biased upward against the underside of the bowl's seat, and a mechanism for movably connecting the lever to the housing, a delivery nozzle for delivering a spray from the spray container generally downward into the bowl. [0015] In a method of delivering the spray to the bowl, a user sits on the bowl's seat and this moves the lever downward pushing down the spray nozzle of the spray container until the nozzle is at maximum deflection delivering a single metered spray to the bowl. Only one spray is delivered even though the user still sits on the seat and the nozzle is fully depressed. Further spray will not occur until the user gets up off of the seat allowing the biasing mechanism to push up on the seat until the spray nozzle is back at its original position, and thereafter the same or a different user sits back down on the seat. BRIEF DESCRIPTION OF THE DRAWINGS [0016] FIG. 1 is a partial perspective view of a device in accordance with a first embodiment of the invention mounted on a toilet bowl and having a seat portion of the bowl sitting on top of the device; [0017] FIG. 2 is an elevational view of the device of FIG. 1; [0018] FIG. 3 is a side elevational view of the device of FIG. 1; [0019] FIG. 4 is a perspective view from an angle below the device of FIG. 1; [0020] FIG. 5 is a bottom view of the device of FIG. 1; and [0021] FIG. 6 is a view similar to FIG. 2 with the device being actuated.
