Abstract: A sprinkler head of visual identification is disclosed. A housing includes a circumference wall, a cap enclosing the circumference wall, and an aperture member alternatively formed on the cap and the circumference wall for dispensing water. A first visual portion is arranged on the circumference wall of the housing and corresponds with the aperture member. A second visual portion, which is visually different from the first visual portion, is arranged on the circumference wall and adjoins the first visual portion. The first and second visual portions constitute the circumference wall of the housing together, a visual differentiation of the first recognition portion and the second one is offered in accordance with the arrangement of dissimilar art elements.

Abstract: A low-flow emitter includes a first housing and a second housing. The first housing includes a first thread portion, and a first passage defined in the first thread portion. The second housing includes a second thread portion, and a second passage defined in the second thread portion corresponding with the first thread portion in a thread connection. Part of the thread connection between the first and second housings is a loose fitting thread connection. A spiral passage is formed along the loose fitting thread connection between the first and second housings. Water flow rate is able to be controlled by a rotation of the first housing with respect to the second housing.

Abstract: A low-flow emitter includes a rotatable cap and a body. The rotatable cap has a threaded hole and a receiving chamber communicating with the threaded hole. The wall of the receiving chamber has plural grooves, which are annularly arranged in a spaced manner around the threaded hole. The body has a shaft. The shaft has an external thread and a flexible rib adjacent to the external thread and is connected to the rotatable cap by threaded connection between the external thread and the threaded hole such that the flexible rib is engaged in one of the grooves. When the rotatable cap is rotated to adjust the amount of water delivered by the low-flow emitter, the area of contact between the grooves of the rotatable cap and the flexible rib of the body stays unchanged, allowing the rotatable cap to produce a consistent feel to the operator.
