A waterless urinal cartridge, for waterless urinals, includes a housing and a cover. The housing includes a waste reservoir configured to hold a predetermined volume of wastewater, and a drainage aperture configured so that an amount of wastewater exceeding the predetermined volume of wastewater flows through the drainage aperture to exit the housing. The cover is coupled to the housing and includes a sealing fluid reservoir having walls that define the waste reservoir and the drainage aperture, the walls of the sealing fluid reservoir form a containment perimeter with an open bottom so as to contain a sealing fluid floating on top of the predetermined volume of wastewater, and a plurality of fluid passages direct wastewater from the fluid bowl to the sealing fluid reservoir. The waste reservoir includes a fluid flow control feature that restrains wastewater movement within the waste reservoir in response to a change in vehicle dynamics.

The present invention has its application in the industry of manufacturing bathroom furniture, specifically in the industry of manufacturing urinals or dry urinals, that is, urinals or dry urinals that do not drag waste through water. The advantage of our valve with respect to the valves of the prior art, is that our water seal does not require dragging water; it is the urine itself that achieves the seal without the odor developed by the urine of the water seal returning to the users' space; it incorporates an additional seal of spheres the use of consumables in the product, such as sealing oil, scent pads, among others. Structurally, our invention consists of an outlet valve, in a waterless urinal, towards the drainage, to prevent the return of foul odors, characterized by comprising a hydraulic trap formed by a tank where a certain volume of urine is formed, a funnel that discharges the new urine into the bottom of the tank, and an upper valve where the seal is carried out by one or two spheres in their respective seats.

A hybrid flushing system for water free urinals is presented with a housing having a wall portion forming a cavity for receiving a cartridge. The housing also includes a flushing fluid inlet portion for receiving a flushing fluid and a flushing fluid directing portion configured to direct the flushing fluid. A cartridge for installation into a housing is presented, including a cartridge wall, a flushing fluid receiving portion and a flushing fluid directing portion to direct flushing fluid received to any portion to clean areas of the housing, the cartridge, and connected plumbing. Steps for cleaning a hybrid flushing system are presented with an act of directing a flushing fluid into an area, where the area is one of a cartridge for a hybrid flushing system, a housing for a hybrid flushing system, and a plumbing system connected with the hybrid flushing system.

The present disclosure provides a return gas prevention device for a drainage pipe, belonging to the technical field of drainage pipes. The device realizes two functions of water seal and a check valve simultaneously, as well as prevents gas channeling in a drainage process.

A sink strainer basket includes a strainer body and an odor prevention arrangement. The odor prevention arrangement includes a drain regulator and a filtration handle. The drain regulator is provided on the strainer body to fully occupy a drainage opening. The drain regulator includes a main drainer body having a sewage passageway, and a blocking assembly movably mounted on the main drainer body to normally close the sewage passageway. The filtration handle extends from the drain regulator to be supported in a drainage cavity. When liquid and larger items are drained in the sink strainer basket, the larger items are filtered by the filtration handle, while the liquid is allowed to pass through the filtration handle to push the blocking assembly to open for draining of the liquid through the sewage passageway.
