Abstract: The invention relates to the structure of a water inlet device of a water tank, wherein a float seat is slipped outside an external water-lifting pipe, an internal water-lifting pipe is installed inside the external water lifting pipe, a control valve is fixedly connected on the upper end of the external water-lifting pipe, a valve set is set inside the control valve, the valve set includes a membrane, a positioning plate, a silencing washer, a water feeding plate and a water supply pipe. The shock and vibration caused by inflowing water current may be buffered by using the construction of the valve set, to thereby enhance the silence effect and achieve the purpose of reducing noise.

Abstract: The present invention relates to a pressure boosting showerhead, which consists of a housing, a ball shape connector, a rear holder, an inner holder, a separation header and an water outflow dish. Wherein, a bending second air passage and a second inlet chamber are set between the inner barrel of the rear holder and the cone tip of the inner holder. The second inlet chamber is communicated with the first inlet chamber in the housing. The second inlet chamber is communicated with the mixed chamber of the inner holder through the second air passage, to prevent water flow reversely penetrating into the air circulation path and boost pressure to maintain the water outflow of the showerhead with better impact strength to thereby achieve the purpose of saving water.

Abstract: The present invention relates to a toilet flushing device including an outer casing, a gear set, a ring disk set, a connecting rod set and a drive set; wherein the drive set includes a toilet flushing handle. By pressing or lifting the toilet flushing handle towards different directions, the discharged water amount can be controlled accurately and thereby achieves the goal of water saving.
