A ventilated toilet includes a bowl with a rim including a rim conduit with a plurality of flush apertures that open to the bowl. A drain conduit communicates with a waste outlet of the bowl and includes a stack outlet for communicating with an associated waste stack. A trap is located in the drain conduit between the waste outlet of the bowl and the stack outlet of the drain conduit for containing liquid that blocks airflow through said drain conduit. A neck is located adjacent the rim of the bowl and includes a neck conduit in communication with the rim conduit. A water tank is connected to the neck and includes an internal space for holding water that is in communication with the neck conduit. A lid covers an open upper end of the tank. A flush valve is located in the tank and selectively opens to allow flow of water from the internal space of the tank to the neck conduit. An overflow tube is in communication with the neck conduit and includes an open upper end that is located above a water level of the internal space of the tank. An exhaust blower includes a blower inlet and a blower outlet. A blower inlet conduit connects the blower inlet to the internal space of said tank, and the blower inlet conduit includes an open upper end that is located above the water level such that the open upper end of the blower conduit is spaced-apart from the open upper end of the overflow tube. The blower outlet is in communication with the drain conduit downstream from the trap between the trap and the stack outlet. A check valve is located between the blower outlet and the drain conduit for preventing odorous air from flowing upstream into the blower outlet, wherein said check valve is adapted to selectively open when said exhaust blower is activated.

An assembly for filtering toilet bowl odors including first and second housings respectively disposed in spaced relation to and in fluid communication with the toilet bowl. A conduit connects interiors of the first and second housings in fluid communication with one another. A fan assembly is mounted within said first housing in fluid communicating relation with the second housing, via the conduit, and is disposed and structured to define a path of fluid flow extending from an inlet of said second housing, through said conduit and a filter assembly, disposed in the first housing and/or second housing, to the exterior of said first housing, concurrent to activation of the fan assembly.

A toilet bowl ventilation system exhausts air in and around the toilet bowl to an area adjacent to the room in which the toilet is located. The toilet bowl ventilation system includes an odor exhaust system which is configured to be installed within the interior cavity of a toilet. The odor exhaust system includes a fan positioned within a housing. The system further includes a controller that regulates power to the fan. Upon activation, the system is operable to transport air from in and around the toilet bowl, through the housing, and to an area adjacent to the room in which the toilet is located (e.g. outdoors).

A smart deodorization device with a cover plate includes a reaction chamber having a reaction cavity; an air extraction unit, configured for extracting odor in or near a toilet pool into the reaction cavity; and a water supply unit, configured for supplying water to the reaction cavity. When working, the air extraction unit extracts the odor into the reaction cavity, and the odor is mixed with the water in the reaction cavity to be converted into purified gas and then discharged from the reaction cavity. By using the characteristic that ammonia molecules in the odor are easily soluble in water, the odor and water are mixed in the reaction cavity and then discharged to realize the gas purification. Thus, the device has obvious effects, simple structures, lower costs, and convenience to use without need of replacing filtering materials.

The present disclosure provides a driving part of a warm air heater and the warm air heater, wherein the driving part comprises a driving circuit board, and a silicon-controlled element is arranged on the driving circuit board; the driving circuit board is arranged in an air duct of the warm air heater, and the driving circuit board is positioned at the upstream of the heating part or is flush with the heating part, wherein the upstream or the flush is based on the direction of air flow in the air duct. The driving part of the present disclosure utilizes the fan to cool the silicon-controlled element without adding large-area radiating fins, thus reducing the cost of the driving part, and the driving circuit board is not arranged on the main control circuit board anymore, thus realizing the miniaturization of the main control part.

A toilet equipment includes a main body provided with a dirt-holding cavity for collecting excrement; a flushing assembly arranged in the main body of the equipment for flushing the dirt-holding cavity; and a suction assembly including a suction pipe provided with an air inlet and an air outlet, a filter arranged between the air inlet and the air outlet, and a negative pressure source connected to the main body of the equipment and configured to provide airflow from the air inlet into the suction pipe. The air inlet is used to inhale the air into the dirt-holding cavity under the action of the airflow of the negative pressure source. In the above manner, the embodiments of the present utility model can effectively improve the situation that the aerosol formed during the flushing process of the toilet equipment is likely to exist in the area of the dirt-holding cavity.
