Technical Field
[0001] The utility model belongs to the technical field of faucets, relates to a water nozzle, and particularly relates to a leak-proof water nozzle. Background Art
[0002] A water nozzle, usually also called a faucet, is a device installed on a water pipe for controlling the opening and closing of water flow and regulating the water flow rate.
[0003] Components such as the valve core and control rod inside the water nozzle may cause water leakage due to wear after long-term use. For example, the sealing surface of the valve core wears, the gap between the control rod and the packing increases, etc., which may all cause water leakage. In order to reduce the waste of water source, targeted research and development on water nozzle leak prevention is required. Summary of the Invention
[0004] The purpose of the utility model is to provide a leak-proof water nozzle with manual control closing for the above problems existing in the prior art.
[0005] The purpose of the utility model can be achieved by the following technical solutions: A leak-proof water nozzle, characterized in that it includes a water nozzle body provided with a water inlet and a water outlet, and an installation cavity is also provided on the water nozzle body. The installation cavity, the water outlet and the water inlet are communicated with each other. A hydraulic tappet is provided in the installation cavity. A control rod is provided at the bottom of the hydraulic tappet. A valve piece I is provided at the bottom of the control rod. A limiting ring that abuts against the valve piece I is provided in the water outlet. An installation thread is provided on the limiting ring, and a hexagonal plug is provided on the installation thread. A valve piece II is movably connected to the bottom of the hexagonal plug. A plurality of positioning blocks protrude from the top of the valve piece II, and a plurality of positioning grooves are provided on the hexagonal plug. A limiting boss is provided on the limiting ring, a support spring is provided on the limiting boss, a limiting block is provided on the control rod, and a limiting cavity is provided on the top of the valve piece II.
[0006] In the above-mentioned leak-proof water nozzle, a sealing partition layer is provided in the installation cavity, and a support spring is provided between the sealing partition layer and the hydraulic tappet.
[0007] In the above-mentioned leak-proof water nozzle, a pressing key cap is provided at the top of the hydraulic tappet, and a rotating nut is provided on the pressing key cap.
[0008] In the above-mentioned leak-proof water nozzle, an anti-collision rounded corner is provided on the rotating nut.
[0009] Compared with the prior art, the leak-proof faucet controls the opening and closing of the water passage by moving the control valve plate through a hydraulic tappet. When aging and leakage occur, the positioning block is embedded in the positioning cavity by rotating the valve plate two to close the passage. The limiting block can connect the control rod and the valve plate two, enabling the valve plate to reopen the water passage under the extrusion of the hydraulic tappet again, facilitating the use of the faucet before maintenance.
