A gas detection system includes a first sensor unit that outputs a voltage corresponding to a concentration of a specific gas, a storage tank capable of storing a sample gas or a purge gas to be supplied to the first sensor unit, and a control unit. The control unit detects a type and a concentration of a gas contained in the sample gas on the basis of a detection result of the first sensor unit. The control unit sets a collection period during which a gas in a predetermined space is collected into the storage tank as the sample gas or the purge gas and a supply period during which the sample gas or the purge gas is supplied to the first sensor unit such that the collection period and the supply period fall in different time slots.

The object of the present invention is a urinal apparatus fitted, in particular, with a special connection to which a duct is connected in order to extract the aerosol generated during its use, by means of an electric exhaust unit that expels the aerosol outside the bathroom, thus preventing it from being diffused inside the room.

The disclosure relates to a portable waste collection and sanitation system designed to handle liquid and solid waste, and while conserving water and minimizing odors. The sanitation system is also designed with modular components adapted for in-home installation, where the system can be quickly disassembled and relocated as needed, such as for moving the components to a new location based on environmental conditions.

The present disclosure relates to a digital control device based on artificial intelligence, belonging to the technical field of intelligent control. The digital control device based on artificial intelligence used by the present disclosure can comprehensively monitor the environmental data including temperature, humidity, smoke concentration, oxygen content, infrared temperature signals, etc. in real time by providing a control system, an environmental monitoring system and an actuating system, and generate control instructions through the monitored environmental data so that the actuating system can make corresponding actions accordingly, thus solving the problems existing problems in the prior art that the monitoring comprehensiveness is low, misjudgments or missed judgments are easy to occur, sensors cannot collect external environmental information in a time-sharing manner, and the practicability and service life are short.

A toilet dehumidifier assembly for draining reclaimed water into a toilet tank includes a toilet tank lid that has an opening extending through the toilet lid. The toilet tank lid is positionable on a toilet tank. A dehumidifier is attachable to the toilet tank lid to remove moisture from ambient air surrounding the toilet tank. The dehumidifier is aligned with the opening in the toilet tank lid to drain water into the toilet tank. A container is positionable inside the toilet tank to capture the water drained from the dehumidifier.

The present invention relates to an air admittance valve (AAV) that operates automatically at low pressures to selectively open and close an air passageway between an inlet and an outlet. The AAV comprises a valve body having a centrally disposed, internal valve chamber in communication with the ambient environment, and having a valve seat. The AAV includes a sealing member having a flexible diaphragm that is fastened to a support ring, the ring defining one or more lugs on an outer periphery thereof. The AAV further includes a cap member within which the sealing member may be disposed, such that the one or more lugs may interact with an interior surface of the cap. The sealing member may selectively seal or unseal from the valve seat in response to pressure differentials between the inlet and the outlet.

A temporary restroom may form a complete enclosure, including a front wall, a back wall, two sidewalls, a floor, a ceiling, and a door. The front wall, the back wall, the two sidewalls, the floor and the ceiling each includes multiple support members, which together form a frame. Inside the enclosure, the temporary restroom includes a, coupled with a waste drainage pipe, a sink in, coupled with a water pipe and a waste water drainage pipe, and multiple connections for connecting the waste drainage pipe and the waste drainage pipe to waste plumbing, connecting the water pipe to water plumbing, and connecting the temporary restroom to a source of electric power. The temporary restroom does not include a waste storage tank or a built-in source of water.
