摘要： Odoriferous gases are drawn from a toilet bowl into a passage of a valve assembly, by a fan. When filled with water, a trap downstream of the fan blocks flow of gases through the passage. Downstream of the trap, the passage is fluidly coupled to a sewer drain. During evacuation, water is drained from the trap into a fluidly coupled reservoir. After evacuation, water is displaced from the reservoir. The displaced water flows back into the trap. A portion of flush water is diverted to maintain the water level in the trap.

摘要： A portable assembly for filtering toilet bowl odors and aerosolized toilet waste which includes a housing, preferably having a removably connected first section and second section. When utilized, the housing is disposed adjacent a toilet bowl and including an inlet and an outlet. In use, the inlet is disposed in direct fluid communication with an interior of the toilet bowl and a filter assembly is disposed within housing in fluid communication with inlet. A fan assembly within the housing includes an electrical power source and is operative to direct fluid flow successively through and from said inlet, downstream through the filter assembly and therefrom to a housing exterior through the outlet, concurrent to activation of the fan assembly.

摘要： An anti-splashback urinal, comprising a bowl for receiving a user's urine, the bowl having a surface with a curvilinear shape designed to reduce the angle of impact between the urine and the surface and to carry the urine down and away from a user; an aperture, through which the user deposits the urine into the bowl, the aperture being off-center with respect to the bowl; and a drain that is offset aligned from the aperture. The urinal may also include a custom outer cover having a shape and color/pattern to complement the room. In a preferred embodiment of the invention, the urinal is equipped with a low flow flush system having an armature that dispenses water at a low flow rate. The armature preferably comprises a plumbing tubing bent into a shape complementary to said urinal, and equipped with misting nozzles. In a particular embodiment, the urinal further comprises an air filter, which optionally may be a water stripper, connected to an air exhaust system, wherein air from the urinal enters the air exhaust system through the air filter, and wherein the air exhaust system is connected to a fan.

摘要： A solution for cleaning and/or sterilizing one or more surfaces in a bathroom is provided. The sterilization can be performed using ultraviolet sources, which can emit ultraviolet radiation directed onto the surface(s). The cleaning can be performed using a fluid, such as water, that is flowed over the surface(s). The surface(s) can include at least a seat of a toilet and/or other surfaces associated with the toilet.

摘要： The invention relates to an improved dual control mode-type deodorising and water drainage valve. The water drainage valve includes a linear control water drainage mechanism and a hydraulic water drainage mechanism controlled by a micro-immersible pump. The linear control water drainage mechanism includes a piston with the piston being partitioned into an upper and lower chamber by a central partition plate; the upper chamber is a piston control chamber for controlling the resetting of the piston, and the linear control water drainage mechanism controls the upward action of the piston; and the lower chamber is a water drainage fluid chamber for creating water pressure on the piston. More than one through hole is provided in the central partition plate to communicate with the upper and lower chambers partitioned by the central partition plate.

摘要： A leak-proof structure of a toilet tank, including a self-sealing actuating device, a string set and a water control device. When the water inlet valve is failure, the water control device is pulled by an end of the inner string of the string set driven by the buoyant cover of the self-sealing actuating device, and a column is released to restore a torsion spring, a shaft is driven to rotate to a stopped water position by the restoring elasticity, and the automatic stop-leaking purpose is achieved.

摘要： A method for removing odors produced in a toilet main unit of a toilet is made available. Specifically, a deodorizing unit having an air expulsion port and an air suctioning port is provided in a rear portion of the toilet main unit, and air is circulated by expelling air through the expulsion port such as to laterally swirl the air along an inner surface of the toilet's bowl, and by suctioning swirled returning air via the suctioning port. Deodorization is carried out in the course of circulating the air.

摘要： A toilet odor removal system and method of use uses an air intake member connected to an air exit member with a fan member attached to the air exit member. When installed, the air intake member is inside the toilet tank and the air exit member is outside of the toilet tank so that the air in the toilet tank and toilet bowl may be evacuated therefrom by activating the fan member to draw the air from both the toilet tank and toilet bowl via the passageway from the toilet tank to the toilet bowl or water overflow tube in communication with a toilet tank. A toilet tank water supply line runs through the air intake member and air exit member.
