The embodiments disclosed herein are directed towards vacuum-assisted toilet systems and methods of using the vacuum-assisted toilet systems. An example vacuum-assisted toilet system includes a toilet bowl defining an outlet and a flush valve fluidly coupled to the outlet. The vacuum-assisted toilet system also includes at least one water source fluidly coupled to the toilet bowl. The water source is configured to supply water to the toilet bowl. The vacuum-assisted toilet system also includes at least one water actuator coupled to the water source. The water actuator is configured to control the amount of water that is supplied by the water source to the toilet bowl. The vacuum-assisted toilet system also includes a controller that is configured to at least partially control the operation of one or more components of the vacuum-assisted toilet system, such as at least one of the flush valve or the water actuator.

An inflatable system is described herein, including a body, a top, a bottom, an interior cavity, and a fluid inlet. In one aspect of the present teaching, the top and the bottom are on opposite sides of the body, approximately parallel to one another. The stem opening is located on the top of the body, wherein the stem opening allows the entry of fluid into the interior cavity of the body. The inflatable system is made of a material which allows for stretching when the inflatable system is inflated.

Multiple apparatuses for flushing portable commodes into a conventional toilet bowl, including a push button fully automated unit that operates by a rechargeable battery. The portable commode is comprised of a waste receiving container and associated housing structure which is adapted to be seated on top of a conventional toilet. The waste container is rotated around 150 degrees and water from the interior of the toilet bowl is forcefully discharge when flushing the portable commode's waste container with electro-mechanical power to guarantee excellent cleaning. Sanitation is adapted to ensure hygienic security.

The present disclosure discloses an anti-siphonage water storage device, a sanitary water supply device, and a sanitary cleaning device. The anti-siphonage water storage device is set in a cleaning water path of a sanitary cleaning device, and the anti-siphonage water storage device comprises a water tank for storing cleaning water. The water tank is disposed with a water inlet structure and a water outlet structure, and the water tank is disposed with an overflow structure. A water outlet surface of the water inlet structure is higher than an overflow surface of the overflow structure.

A toilet includes a bowl with a sump and a trapway connecting the sump to an outlet of the toilet. The trapway has a zeta shape and is configured to induce a siphon which provides pressure to suction waste water from the bowl during a flush cycle. A trapway supply conduit is connected to the trapway in a tangential orientation to an upleg region of the trapway. The trapway supply conduit supplies water to the trapway, which follows a contour of the inner surface of the trapway supply conduit and continues in the same direction into the upleg region of the trapway by relying on a fluid flow to follow the curve of a convex surface placed proximate to the flow.

An odor elimination system includes a tank adapter with passages through which odors from a toilet bowl are drawn. A fan draws the odors from the bowl through the tank adapter into a passage that includes a trap. While the fan is running, the trap is empty. A barrier moves to expose a reservoir. Water from the trap is received in the reservoir, to evacuate the trap. The barrier is moved back into the reservoir to displace water from the reservoir into the trap to block sewer odors from the drain pipe. A sipper diverts a portion of flush water to maintain the trap full.
