Abstract: A flow limiting device with a back flow prevention mechanism includes a body that has an isolation board and a water-through cavity. The isolation board has a water-through hole connecting to the water-through cavity and a flow limiting device having a flow limiting component and stop ribs which limit the position change of the flow limiting component. The stop ribs are arranged on the inner wall of the water-through cavity at equal intervals. The flow limiting component is set in the water-through cavity. The outer side of the flow limiting component is contacted on the stop ribs. A back flow prevention mechanism comprises, a back flow prevention component which is fixed in the water-through hole and a supporting structure which is set for supporting the back flow prevention component when it expands on the inner wall of the water-through cavity.

Abstract: A pressing waterway switch device and shower includes a fixed housing and a pressing switch mechanism, the pressing switch mechanism includes a button, a switching component, and a transmission component, the button, the driving piece and the switching component are all or part of connected with an elastic piece. The pressing waterway switch device is installed in a shower body with the button disposed outside. By pressing the button makes the water outlet function changed in switch manner, and the water outlet function includes shower spray function, massage spray function and shower spray combined with massage spray together.

Abstract: A combined shower with a gravity switch mechanism includes a wall-fixed shower, a handheld shower and a water diversion component, the water diversion component includes a water inlet, two water outlets respectively connected to the wall-fixed shower and handheld shower, and a switching component which is used to switch the waterway communication between the water inlet and two water outlets. The shower also includes a gravity switch mechanism and an attachment portion. The attachment portion interacts with the switching component to drive the activation of the switching component to trigger the switch to make the handheld shower activate or remain static relative to the position of the wall-fixed shower.

Abstract: A water outlet device with rotary outlet function has a fixing part, a driving mechanism, a control mechanism, at least two sliding units and several water outlet nozzles, the water outlet nozzles are movably connected to the fixing part, the sliding unit can slide with respect to the fixing part; the driving mechanism can be driven by the water flow pressure, at least two sliding units are connected with the driving mechanism and driven by the driving mechanism to drive, and at least two sliding units are communicated with the water outlet nozzles in rotary manner around the rotating axis by intersection way. The control mechanism is connected with the driving mechanism and at least two sliding units to control at least one of sliding units to slide, the sliding action of the sliding units connected to the water outlet nozzles cause the water outlet nozzles to move.
