Abstract: A reverse osmosis system may include a water supply, a filter, and a mixing member. The water supply is connected to a first water tube and a second water tube. The first water tube is connected to the filter, and the filter is connected to a drain pipe which is connected to a wastewater tank. The wastewater generated from the filter under reverse osmosis process can be discharged into the wastewater tank. The mixing member has a water inlet end, a water outlet end, and a wastewater inlet tube, which are communicated with each other, and the water inlet end of the mixing member is connected to the second water tube. When water flows through the mixing member, the negative pressure is generated to pump wastewater in the wastewater tank through the wastewater inlet tube into the mixing member, thereby achieving the effect of water saving.

Abstract: An ozone faucet switching structure includes a faucet body, a connecting member connected with the faucet body, an aerator mounted in the connecting member, and a control sleeve mounted on the connecting member. The faucet body has a water outlet pipe which is provided with a conduit which is externally connected with an ozone device. Thus, the control sleeve is movable on the connecting member to stop supply of the ozone when not in use to prevent the ozone from being mixed with the drinking water.

Abstract: The present invention provides a control valve for a water channel, which comprises of, from top to bottom, a control shaft bolt, a sliding valve disc, a fixing valve disc and a valve base. A valve shell combining with the valve base covers around a lower portion of the control shaft bolt, the sliding valve disc and the fixing valve disc to prevent mentioned components from falling out. The amount and the open/close operation of the two different kinds of water sources can be operated and controlled by a single control valve of the water channel to simplify the complexity in structure. Also it is convenient for a user to control the amount and the open/close operation of two different water sources by a single control valve.
