  • Patent number: 9888826
    Abstract: An environment-protection energy-saving barrel is an integral formed by three parts, i.e. an outer barrel, a middle barrel and an inner barrel. The inner barrel is communicated with the middle barrel; the bottom of the middle barrel is provided with a water inlet pipeline; the water inlet pipeline is communicated with the bottom of the outer barrel used for storing water; a water inlet quantity controller is arranged on the water inlet pipeline; the inner barrel communicated with the middle barrel is used for dewatering and cleaning a mop; and the water inlet quantity controller arranged on the water inlet pipeline is used for controlling the water inlet quantity which flows into the middle barrel from the outer barrel and controlling the on/off of a valve of the water inlet pipeline. Therefore the water in the barrel can be repeatedly used.

  • Patent number: 8950019
    Abstract: A lavatory system is disclosed including one or more integrated hand washing stations. Each hand washing station includes a basin, a faucet, a solenoid valve configured to control water flow to the faucet, and an electric hand dryer located adjacent the basin and the faucet so that the user of the washing station may use the faucet and the electric hand dryer without leaving the washing station. The electric hand dryer preferably includes an outlet to direct air across the associated basin so that any water that drips from the user's hands fall within the basin. A control system may be provided to control activation of the fixtures such as the solenoid valve, the electric hand dryer, and/or soap dispenser. The control system may be configured to inhibit simultaneous activation of the solenoid valve and the hand dryer. A photovoltaic system may be provided to provide power.

  • Publication number: 20150013061
    Abstract: A detergent-recycling apparatus includes two containers. The first container includes two inlet ports, an outlet port and a drain valve. The first inlet port allows pressurized air to travels into the first container. The second inlet port allows detergent and contaminants to travel into the first container. The drain valve releases the contaminants from the first container. The second container includes an inlet port and an outlet port. The inlet port of the second container is connected to the outlet port of the first container to allow the pressurized air to carry the detergent into the second container from the first container while the contaminants deposit in the first container. The outlet port releases the detergent as well as the pressurized air from the second container.

  • Patent number: 5287570
    Abstract: A control system for water faucets comprises an on-off control switch located at a sink and actuated by pressure applied and released by the body of the user. When the body of the user pushes forward towards the sink, the switch will be depressed and the water faucets will turn on. When the user backs away from the sink, the switch will be released and close off the flow of water. An overflow reservoir is provided to collect cold water run off prior to the time when hot water makes its way through the water pipes, and a temperature sensor switch and/or alarm controls either an automatic or manual change over from hot to cold water. In addition, a microprocessor and key board control various water delivery functions such as volume and temperature. The control system reduces leakage and saves water which would otherwise be lost due to running the hot water until it becomes heated to the desired temperature.

  • Patent number: 4884725
    Abstract: Disclosed is a water dispensing system for an aircraft wherein hot and cold water supplied to a faucet disposed above a washbasin in a controlled manner including solenoid valves for both the hot and cold water. Two manually operated switches are employed to energize, respectively, the hot and cold solenoid valves. Two different timing cycles are employed. In one timing cycle, when one switch is actuated and then the other switch is actuated within a predetermined time period, both solenoid valves will be turned on to provide approximately equal volumes of water to the faucet for a predetermined time period. In another timing cycle, when one switch is actuated and the other switch is actuated within a predetermined time period, the solenoid valve means energized by the first switch will be turned off and the second solenoid valve will be turned on for a predetermined time period.
