Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

As shown in fig. 1-8, the water tap time-delay water outlet joint comprises a diversion cap 1 and a water accumulator 2; the water guiding cap 1 is a short cylindrical connecting cap, a water guiding hole 1.1 is formed in the center of the water guiding cap 1, the water guiding hole 1.1 is a longitudinal coaxial stepped hole, the upper section of the stepped hole is a threaded water inlet used for being connected with a thread of a water outlet nozzle of a faucet, the lower section of the stepped hole is a funnel-shaped water outlet, and an outer thread 1.2 is arranged on the lower section of the outer circumference of the water guiding cap 1; the water storage device 2 is in a long cylindrical shape, a cylindrical outer sleeve 2.1 is arranged outside the water storage device, an inner screw thread 2.2 is arranged on the inner wall of the outer sleeve 2.1 at the uppermost end, a longitudinal cylindrical inner cylinder 2.4 is arranged on a central fixing frame of the outer sleeve 2.1 at the position below the inner screw thread 2.2 inside the outer sleeve 2.1 through longitudinal ribs 2.3 distributed at intervals along the inner wall of the outer sleeve 2.1, the inner cylinder 2.4 and the outer sleeve 2.1 are coaxially distributed, the lower end face of the inner cylinder is flush, an overflow gap 2.5 is arranged between the outer wall of the inner cylinder 2.4 and the inner wall of the outer sleeve 2.1, the upper end of the inner cylinder 2.4 is open, the diameter of the opening of the inner cylinder 2.4 is larger than the lower opening diameter of a water outlet of the diversion cap 1, the lower end of the inner cylinder 2.4 is an inverted frustum-shaped sealing cylinder bottom, and a small water outlet hole 2.6 is formed in the center of the cylinder bottom; the water accumulator 2 is in threaded connection with the outer thread 1.2 of the lower section of the outer circumference of the diversion cap 1 through the inner thread 2.2 at the upper end of the outer sleeve 2.1, so that the diversion cap 1 and the water accumulator 2 are connected and assembled into a whole up and down, and the water outlet of the diversion cap 1 is positioned right above the opening of the inner cylinder 2.4 of the water accumulator.

The first rubber sealing washer 3 is arranged at the hole bottom of the threaded water inlet of the flow guide cap 1 and used for preventing water leakage at the joint when the threaded water inlet is in butt joint with a water outlet nozzle of a faucet. And a second rubber sealing washer 4 is arranged at the position where the threaded connection part between the diversion cap 1 and the water storage device 2 is pressed by the end face, and is used for preventing the threaded connection part between the diversion cap 1 and the water storage device 2 from leaking water. The diversion cap 1 and the water storage device 2 are made of metal or plastic materials, wherein the outer sleeve 2.1, the longitudinal ribs 2.3 and the inner cylinder 2.4 of the water storage device 2 are integrally formed.

When the water delay outlet joint of the water faucet is used, the net nozzle or the tip nozzle of the water outlet nozzle of the conventional water faucet is firstly detached, and then the joint is connected to the screw threads of the water outlet nozzle of the conventional water faucet through the threaded water inlet and screwed down, so that the function of delaying water outlet for a certain time after the water faucet is closed can be realized. The working principle of the water delay outlet joint of the water faucet is as follows: when the tap switch is normally turned on, the water flow of the tap nozzle flows into the inner cylinder 2.4 of the water storage device 2 through the funnel-shaped water outlet of the flow guide cap 1 and then flows out through the small water outlet hole 2.6 below the inner cylinder 2.4, because the water flow entering the inner cylinder 2.4 is larger than the water flow flowing out from the small water outlet hole 2.6, the inner cylinder 2.4 is filled with water quickly, meanwhile, the redundant water can overflow from the opening at the upper part of the inner cylinder 2.4, and the overflowing water flows out downwards through the overflow gap 2.5 between the inner cylinder 2.4 and the outer sleeve 2.1. After the water faucet is closed, the water in the overflow gap 2.5 automatically flows downwards, as shown in fig. 4, because the lower end of the inner cylinder 2.4 is designed to be in an inverted frustum shape, and the overflow gap 2.5 at the lower end is larger than the overflow gap 2.5 at the upper end, the phenomenon that the water in the overflow gap 2.5 cannot flow out due to the influence of tension cannot occur; after the water in the overflow gap 2.5 completely flows out, the air enters the upper part of the inner cylinder 2.4 of the water accumulator, and the water in the inner cylinder 2.4 of the water accumulator slowly flows out from the small water outlet hole 2.6 at the lower part, thereby realizing the delayed water outlet for a certain time.

The above-mentioned drawings are only exemplary embodiments of the present invention and are not intended to limit the present invention, and any modifications or equivalent substitutions and improvements made within the spirit and principles of the present invention should be included within the scope of the present invention.
