TH3015U - Water dispenser - Google Patents

Abstract

A water dispenser consists of a lower and upper body assembled together. A valve stem is installed within both the upper and lower bodies. The upper body of the valve stem is a solid cylinder with a diameter slightly smaller than its central diameter to create space for water flow. The lower part of the upper body has several holes around its circumference for water to exit. Below these holes is the middle body, whose diameter matches the diameter below the upper shoulder of the upper body. Below the middle body is the lower body, whose diameter matches the diameter below the lower shoulder of the lower body. Both the middle and lower bodies of the valve stem are hollow cylinders. A spring is fitted to the lower body of the valve stem to create resistance, causing the valve stem to retract when the water is not in use.

Claims (2)

1. The water dispenser consists of a lower body (1) which is a vertical central geometric shape in which the upper part of the lower body (1) is the upper part (2), which is a hollow cylinder in which the outer surface is formed into an external thread for fitting into the lower part (4), which is formed into an internal thread of the upper body (3). On one side of the lower body (1) is a cylindrical opening (5) for fitting into the UV lamp (6). The central axis (7) of the lower body (1) is formed into an upper shoulder (8) and a lower shoulder (9) for supporting the valve rod (10) and spring (11), respectively. At the very bottom end of the lower body (1) is a cap (12) which is the opening for closing the water outlet. The upper body (3) is a hollow cylinder in which the central axis (13) of the upper body (3) is formed into an upper shoulder (14). Inside the lower part of the upper body (3) is the lower part (4), which is formed into an internal thread. And inside the upper area of the upper body (3) is formed into an internal thread for fitting into the water inlet pipe, and the valve rod (10) is installed inside the lower body (1) and the upper body (3) which are joined together. Specifically, the valve rod (10) has an upper body (15) which is a solid cylinder with a diameter slightly smaller than the diameter of the central shaft (13) of the upper body (3) to create a space for water to flow into the upper body (3). At the bottom of the upper body (15) there are several holes (16) around the circumference for water to flow out, with the top of the holes (16) being a ridge (17) that rests on the upper shoulder (14) of the upper body (3), and at the bottom of the holes (16) is the central body (18) with a diameter corresponding to the diameter of the lower body (3). The center below the upper shoulder (14) of the upper body (3), where the bottom of the middle body (18) is the lower body (19) with a diameter corresponding to the diameter below the lower shoulder (9) of the lower body (1). 2. The water dispenser, as per claim 1, where the middle body (18) and the lower body (19) of the valve stem (10) are hollow cylinders to serve as channels for water flowing out of hole (16) to flow through for further use, and a spring (11) is fitted over the lower body (19) of the valve stem (10) to create a force that causes the valve stem (10) to retract when not in use, with the spring (11) positioned on the lower shoulder (9) of the lower body (1).
