    Abstract: Disclosed is a water seal device for removing odour of a toilet. The water seal device is mounted in a toilet tank, and consists of an exhaust assembly, a water seal backflow assembly and an electronic control assembly. The device is provided with a powerful exhaust electric motor. After starting, the electronic control assembly supplies power to the exhaust electric motor, and the exhaust electric motor can inhale a gas in a bowl into the tank. Water in a U-shaped trap water seal is pushed and pressed out by means of the gas pressure. When the toilet discharges sewage, the electronic control assembly automatically cuts a power supply, and the exhaust electric motor stops working, and the U-shaped trap water loses the pressure to block gas return.

    Abstract: An occupant-tracking fan apparatus is provided with a source of forced air such as a fan nozzle in a movable support with multi-axis positioning and a controller with sensors controlling the moveable support directing forced air toward a target detected by the sensors. Targeting in real-time can be through camera imaging or with an array of ultrasonic transmitters/receivers that can identify occupant shape, range and thermal profile, even when the occupant is moving. The targeting fan cools by aiming a stream of air at the occupant increasing skin convection. The apparatus can also target thermal extremes and de-stratify air temperature gradients. Settings can be individualized by remote control, RFID tag or even prescribed gestures interpreted by the camera and controller. The apparatus may be part of a building wide system with a central controller that monitors sensors, controls each fan and the building HVAC systems.

  • Patent number: 10480168
    Abstract: The automated toilet comprises a toilet with a motorized pump in line with the drain pipe, a sensor, a control box, and a flush valve actuator. The sensor detects the presence of a user in front of the toilet and notifies the control box. When a user arrives, the control box starts the pump to draw air through the rim and into the sewer line, which removes odors while the toilet is being used. When the user leaves, the control box activates the flush valve actuator, causing the toilet to flush. The control box may run the pump for a predetermined time interval so that the pump may assist in emptying the bowl. When the bowl has emptied, the pump may continue to draw odors from the bowl until the control box shuts the pump off.

    Abstract: A universal flushing lever for a toilet that can be mounted on different areas of the toilet tank, during flushing action, triggers the closing of the toilet seat cover and or seat using magnetic fields. A magnet is attached to a universal flushing lever as well as the seat cover and/or seat. When the flushing lever is actuated it uses the magnet's fields to trigger the cover and/or seat closure. The magnets can be positioned to use the magnetic fields in two ways, repulsion or attraction individually or in conjunction. In the repulsion scenario, the magnets, one positioned on the flushing lever and one on the cover and or seat, once in proximity forces the closure of the adjacent cover and or seat. In the attraction scenario, the magnets, one positioned on the flushing lever and one on the cover and or seat, once away from proximity allows the closure of the adjacent cover and or seat.

  • Patent number: 9422703
    Abstract: An odor-removing hinge system and method of use for withdrawing noxious odors from toilets and portable commodes is disclosed. The present seat hinge system includes an integrated housing that functions as a portion of an exhaust pathway for noxious gases expelled within the toilet bowl. The present hinge system includes at least one hollow bolt disposed in fluid communication with the housing, which is used to secure the toilet seat to the toilet. In one embodiment the noxious gases within the toilet bowl are carried by convection or vacuum via connective tubing to an exhaust conduit installed in an adjacent wall. In other embodiments the noxious gases are directed through a detachable air filter assembly secured to the housing and the odorless filtered air is recirculated. In a method of use the present hinge system is retrofitted to existing toilets and portables commodes in replacement of standard toilet seat hinges.

  • Patent number: 9399862
    Abstract: An improved odor extracting apparatus and system are disclosed. The disclosed embodiments provide an exhaust vacuum for a toilet with associated venting installed through existing walls, windows, ceilings, or other outlets. The exhaust apparatus suctions air and aerosol particles from the toilet bowl to prevent lingering odor in the restroom and areas proximate to the restroom. Embodiments of the disclosed odor extractor are installed either independently of the toilet seat or incorporated in the toilet seat manufacturing process. Exemplary models fit any make of toilet seat and are interchangeable between toilet seats. The disclosed odor extractor is low in both noise and vibration.

  • Patent number: 9346617
    Abstract: This device will help to eliminate or greatly reduce the odor in a compactor that is caused by garbage and rotting waste. This, in turn, will help eliminate the amount of flies and/or maggots which surround a compactor because the smell, which attracts flies will be reduced. A predetermined amount of deodorizing pellets are distributed in a compactor at predetermined times.

  • Publication number: 20150082525
    Abstract: An odor dispersion assembly for dispersing an odor from a receptacle to an external exhaust through an existing structure and at least one existing pipe. The assembly is operable to suck the odors at a proximal point to their discharge. A receptacle receives a discharge. The receptacle includes a seat for providing a surface for a user to sit for performing the discharge. The seat include at least one aperture that receives and directs the odor to a cavity within the seat. A pressure differential portion sucks the odor from the cavity. The odors passes through a dispersion tube behind the toilet, and through an existing barrier. The dispersion tube joins with at least one existing pipe and tubing behind the existing barrier. The existing pipes carries the odor to an exhaust portion. Existing pipes and structures are used to minimize costs.
