Anti-falling water-stop converter

Abstract

The invention discloses an anti-falling water-stop converter comprising an adapter and a quick coupling. The lower end of the adapter is provided with a water outlet nozzle, and the quick coupling isconnected to the water outlet nozzle of which the lower end is provided with a water outlet; the adapter is internally provided with a piston inner core movably inserted into the water outlet, and theupper end of the piston inner core is provided with a plug matched with the water outlet hermetically; the lower part of the piston inner core is a hollow pipe body, and the peripheral wall of the piston inner core is provided with a water through hole; the quick coupling is internally provided with a stop block which abuts against and is connected to the lower end of the piston inner core, and under the limitation of the stop block, the piston inner core is jacked; the water through hole is located in the adapter and communicates with a waterway, and a first sealing ring is arranged betweenthe quick coupling and the water outlet nozzle; and the upper end of the adapter is connected to a connector. In case the quick coupling falls accidentally, the piston inner core is out of limit, andthe water outlet of the water outlet nozzle is blocked by the plug of the piston inner core under the pushing effect of water flow, so that water is stopped automatically; and the seal is ensured under the effect of water pressure, and ceaseless water flow is avoided.

Description

technical field [0001] The invention relates to the technical field of waterway equipment, in particular to a detachment-proof and water-proof converter. Background technique [0002] The traditional washing machine faucet itself does not have a water stop function. If the hose of the washing machine is not clamped tightly to the faucet, the hose will fall, or the water pressure changes suddenly or the water pipe and the faucet encounter a sudden change during use after the faucet is connected to the water pipe. When the connection part is damaged and fails, the water pipe is easy to fall off and the water flow will not stop. In the absence of personnel present, it will lead to flooding of the floor or serious waste of water resources and other property losses, and even cause safety problems. At present, there are many washing machine faucets with water-stop function, some of which are equipped with a water-stop device at the junction of the water inlet pipe and the faucet, ...

Problems solved by technology

[0002] The traditional washing machine faucet itself does not have a water stop function. If the hose of the washing machine is not clamped tightly to the faucet, the hose will fall, or the water pressure changes suddenly or the water pipe and the faucet encounter a sudden change during use after the faucet is connected to the water pipe. When the connection part is damaged and fails, the water pipe is easy to fall off and the water flow will not stop. In the absence of personnel present, it will lead to flooding of the floor or serious waste of water resources and other property losses, and even cause safety problems.

At present, there are many washing machine faucets with water-stop function, some of which are equipped with a water-stop device at the junction of the water inlet pipe and the faucet, and some are added with a water-stop device inside the faucet. The structure is relatively complicated, which brings high manufacturing costs, Problems such as inconvenient operation need to be improved
