Abstract: The present utility model provides a magnetic suspension drain, comprising a first connecting member and a second connecting member that are connected with each other and adapted to respective connection to a drain opening of a drain device and a drain pipe. The magnetic suspension drain further comprises a magnetic suspension inner core arranged in the first connecting member, and the magnetic suspension inner core comprises a rotary floating rod and a rotary sealing cover. The rotary floating rod is provided with a first magnet, and a repulsive second magnet is provided inside the first connecting member.

Abstract: The present utility model provides a modularized induction flushing device for a urinal and an induction urinal. The modularized induction flushing device comprises a water inlet and outlet assembly, a water drainage assembly, an electromagnetic valve assembly, and a power supply assembly, wherein the modularized induction flushing device further comprises an induction module, the induction module is associated with the electromagnetic valve assembly and is attached to the water inlet and outlet assembly and/or the water drainage assembly, wherein the induction module is configured to be switched between at least two induction modes in a replaceable mode, and the electromagnetic valve assembly responds to different induction modes of the induction module to control flushing of the urinal.

Abstract: Apparatuses are described that provide for a mobile eye washing station. An example station includes a fluid storage cartridge that stores unused eye wash fluid and a nozzle assembly in fluid communication with the fluid storage cartridge. In operation, the nozzle assembly dispenses the unused eye wash fluid stored in the fluid storage cartridge via one or more nozzles of the nozzle assembly. The example station further includes a waste fluid collection basin that, in operation, collects eye wash fluid dispersed by the nozzle assembly. Due to contact with the fluid storage cartridge, the waste fluid collection basin compresses the fluid storage cartridge to drive fluid communication between the fluid storage cartridge and the nozzle assembly. The fluid storage cartridge is disposed vertically beneath the waste fluid collection basin.

Abstract: Methods, apparatuses, and systems for detecting internal defects of a protective headgear are provided. An example apparatus may include a protective headgear, an actuator element integrated within the protective headgear, a sensor element integrated within the protective headgear, and a processor element electronically coupled to the actuator element and the sensor element. In some examples, the processor element is configured to cause the actuator element to generate a first ultrasonic wave, wherein the first ultrasonic wave is propagated in the protective headgear, and receive a first output from the sensor element in response to the first ultrasonic wave.
