Abstract: A soap dispenser includes a spout; a controller; a barcode scanner electrically connected to the controller; a power supply electrically connected to the controller; and a soap reservoir including a label having a barcode containing information including a set count of dispensing times of the soap reservoir and a current count of dispensing times of the soap reservoir. The spout includes an electromagnetic switch, an infrared sensor, and a pump in fluid communication with the soap reservoir and electrically connected to the electromagnetic switch respectively. The barcode scanner scans the barcode and sends same to the controller for storage. The controller compares the set count of dispensing times of the soap reservoir with the current count of dispensing times of the soap reservoir prior to activating the pump. After the pumping, the controller increases the current count of dispensing times of the soap reservoir by one.

Abstract: A lotion pump includes an internally threaded sleeve; a spring-loaded dip tube including an annular first flange on an outer surface, and an internal shoulder; a first housing including a tapered head, a chamber spaced from the tapered head, a tunnel communicating between the tapered head and the chamber, overflow openings on the tunnel, and first external threads on an outer surface of the chamber; a check valve; a second housing including an open first chamber member, an open second chamber member, a channel communicating between the first chamber member and the second chamber member, second external threads, and an annular second flange on an outer surface; a support including an annular third flange on an outer surface, and an second opening; a spring-loaded valve; and an internally threaded cup including an annular fourth flange on an outer surface, and a second hole through a second end.

Abstract: An electric soap dispenser is provided with a housing; a cover; a reservoir; a valve; a nozzle; an electric motor; a gear system; an arm having one end rotatably disposed in the gear system; a link having one end pivotably secured to an other end of the arm and loosely put on the nozzle; an electric control unit; a sensor; and a power source. The electric control unit actuates the electric motor upon receiving a signal from the sensor, the actuated electric motor rotates the gear system, one end of the arm rotates 180-degree to move the link upward to open the valve thereby flowing liquid soap from the reservoir to the nozzle, and one end of the arm rotates further 180-degree to move the link downward to close the valve thereby stopping the flowing and deactivating the electric motor. Power demand is greatly reduced when in use.

Abstract: A device for sealing a used feminine hygiene article is provided with a trash can; a sealing mechanism on top of the trash can and including a frame, a power supply, sensors disposed on the frame, a controller, a motor, two opposite rollers each including two gears on both ends respectively, the gears of one roller being meshed with the gears of an other roller, and a gear member meshed with one gear of one roller and operatively connected to the motor, and two rolls of thermoplastic rotatably supported by the frame and disposed above both the rollers wherein a gap is formed between the rollers, and open ends of the thermoplastics of the rolls of thermoplastic are pushed into the gap to engage each other; and a cover on top of the sealing mechanism and including a releasable ring member having a channel above the gap.

Abstract: The present invention discloses an improved handheld sprayer structure comprising an electric sprayer and a liquid container. The liquid container is filled with an appropriate amount of liquid, and this device is held by a hand, and a press button is pressed to trigger a start switch, such that a drive gear installed on a motor transmission shaft drives a plurality of wheels installed on a large gear to compress a hose to produce a suction, so as to suck the liquid in the liquid container upward, and spray the appropriate amount of liquid continuously and steadily from a spray head.
