Abstract: A sand-proof sprinkler mechanism has a base. A housing and a connecting platform are provided on the base. A hose is rotatably connected between the housing and the connecting platform. The housing has a water outlet, a housing inner chamber and a water inlet that are in communication with the hose. The housing includes an impeller transmission member and a transmission device that is drivingly connected to the impeller transmission member and the hose. The housing further has a sealing chamber for mounting the transmission device. A water baffle is provided at an opening of the sealing chamber for covering the sealing chamber. The above structure prevents particles from entering and getting stuck.

Abstract: An adapter with two male threads includes an integrally-connected body and a hanger. The two ends of the body are penetrated by a through hole and each have an external thread segment. The body has two spaced-apart flanges between the two external thread segments. A groove is formed between the two flanges. One end of the hanger has a first connecting portion connectedly disposed in the groove. The other end of the hanger has a second connecting portion connected to an external object. Therefore, two water pipes each having a female thread connection end can be connected by the two external thread segments of the body to ensure ease of use and cut manufacturing costs.

Abstract: A water sprinkler includes a housing and an ejection head. An impeller is assembled in the housing, pushed by water, and connected to a cam. A water-hit target is pivoted with the housing via a compression spring, and an impacted portion of the water-hit target is extending outside of the housing. The water-hit target repeatedly impacts the housing because of the pivoting motion caused by the pushing of water flow and by the pulling of the compression spring, so that the housing is pivoted to change the ejection direction of the ejection head. A water baffling cover is pivoted with the housing. A abutted member is assembled on the water baffling cover and abutted against the cam. The cam can push the abutted member to drive the pivoting motion of the water baffling cover, so that the water baffling cover shields the ejection head by different extents.

Abstract: A sprinkler structure includes a base with a rotatable stripe-shaped pipe and spraying pipes installed on the stripe-shaped pipe. The stripe-shaped pipe has an end connected to the base through a hollow shaft which has an outlet pipe, and the other end connected to the base through a pipe plug. A water fetching device is installed at an end of the base for driving the stripe-shaped pipe to rotate and includes a sleeve sheathed on the hollow shaft. A water fetching target is installed at an upper end of the sleeve and near the outlet of an outlet pipe. The base has an inlet pipe interconnected with the hollow shaft, the outlet pipe and the spraying pipe, and further has a conversion device for controlling the water fetching device to rotate in a forward or reverse direction.

Abstract: A warning device for determining water flow status includes a main body having a flow channel penetrating through both ends of the main body and an opening on a side of the main body, and an intersection of the flow channel and the opening define a working chamber. The working chamber includes a power generating device with a pivoting turbine blade and a light emitting element. The turbine blade is pushed by water flow to generate electric power to the light emitting element to emit light. The power generating device includes a flow diverting element having a slot compartment formed by a shaft cover and a sidewall, and the turbine blade is disposed therein. A plurality of flow diverting holes are disposed on the flow diverting element for flowing water into the slot compartment to push and move the turbine blade.
