The main body includes a sensing device and a pump. The container includes an odor shielding compound. The electronic toilet odor shielding device is placed and attached within a toilet water tank of a toilet. The sensing device is configured to sense a toilet water tank flush event and to trigger the pump to draw the odor shielding compound from the container and subsequently to dispense the odor shielding compound into a toilet bowl of the toilet. The odor shielding compound that is dispensed into the toilet bowl forms an odor shielding film on top of a water surface within the toilet bowl. ## Claims ### Claim 1 An electronic toilet odor shielding device comprising: a main body comprising a sensing device, a controller, and a pump; a container comprising an odor shielding compound; wherein the electronic toilet odor shielding device is configured to be placed and attached to a toilet water tank of a toilet; wherein the sensing device is configured to sense a toilet water tank flush event and communicate the toilet water tank flush event to the controller; wherein the controller is programmed to trigger the pump to draw the odor shielding compound from the container upon receipt of the toilet water tank flush event and subsequently to dispense the odor shielding compound into a toilet bowl of the toilet, after a delay time; wherein the sensing device comprises one or more pins that change electrical conductivity based on a medium they are embedded in. ### Claim 2 (depends on 1) The device of claim 1, wherein the main body is seamless and waterproof, and the container is attached to a side slot of the main body and the side slot is sealed by the container. ### Claim 3 (depends on 1) The device of claim 1, further comprising a first tube and a second tube and wherein the pump draws the odor shielding compound from the container via the first tube and subsequently dispenses the odor shielding compound into a toilet bowl of the toilet via the second tube. ### Claim 4 (depends on 3) The device of claim 3, wherein an open end of the second tube is placed within an overfill tube of the toilet water tank. ### Claim 5 (depends on 1) The device of claim 1, wherein the main body further comprises a power source that provides power to the pump. ### Claim 6 (depends on 5) The device of claim 5, wherein the power source is a battery pack. ### Claim 7 (depends on 1) The device of claim 1, wherein the one or more pins are metal pins that protrude from a side of the main body. ### Claim 8 (depends on 1) The device of claim 1, wherein the controller comprises a programmable printed circuit board (PCB) and wherein the programmable PCB controls the ON/OFF operation of the pump based on signals received from the sensing device. ### Claim 9 (depends on 8) The device of claim 8, wherein the programmable PCB is configured to program a start time of the toilet water tank flush event and a volume of a dose of the odor shielding compound that is to be dispensed within the toilet bowl with each toilet water tank flush event. ### Claim 10 (depends on 8) The device of claim 8, wherein the controller performs periodic checks of the sensing device. ### Claim 11 (depends on 8) The device of claim 8, further comprising an additional container comprising a cleaning solution, and wherein the programmable PCB is programmed to periodically trigger the pump to draw the cleaning solution from the additional container and subsequently to dispense the cleaning solution into the toilet bowl. ### Claim 12 (depends on 1) The device of claim 1, wherein the odor shielding compound comprises one of odor shielding oils, emulsifiers, thinners, scents, bubble forming liquids, and coloring agents. ### Claim 13 (depends on 1) The device of claim 1, wherein the odor shielding compound that is dispensed into the toilet bowl forms an odor shielding film on top of a water surface within the toilet bowl. ### Claim 14 (depends on 1) The device of claim 1, wherein the odor shielding compound forms an emulsion with toilet bowl water that encapsulates solid waste. ### Claim 15 (depends on 1) The device of claim 1, wherein the main body is attached to an inner side of the toilet water tank so that the sensing device is submerged in water contained in the toilet water tank and wherein the sensing device emerges out of the water contained in the toilet water tank and becomes dry when the toilet is flushed and the water contained in the toilet water tank empties into the toilet bowl. ### Claim 16 (depends on 15) The device of claim 15, wherein the main body is attached to the inner side of the toilet water tank via one of mechanical connection, magnetic connection, adhesive connection, a hook or a hook and loop type of connection. ### Claim 17 (depends on 1) The device of claim 1, wherein the electronic odor shielding device is programmed to wait three seconds between sensing of the toilet water tank flush event and dispensing of the odor shielding compound into the toilet bowl. ### Claim 18 (depends on 1) The device of claim 1, wherein the main body is attached to an outer side of the toilet water tank. ### Claim 19 A toilet odor shielding method comprising: providing an electronic toilet odor shielding device comprising a main body and a container, wherein the main body comprises a sensing device a controller, and a pump and wherein the container comprises an odor shielding compound; placing and attaching the electronic toilet odor shielding device to a toilet water tank of a toilet; and sensing a toilet water tank flush event via the sensing device and communicating the toilet water tank flush event to the controller; wherein the controller is programmed to trigger the pump to draw the odor shielding compound from the container upon receipt of the toilet water tank flush event and subsequently to dispense the odor shielding compound into a toilet bowl of the toilet, after a delay time; wherein the sensing device comprises one or more pins that change electrical conductivity based on a medium they are embedded in.
