Quick connector capable of achieving water self locking

Abstract

The invention discloses a quick connector capable of achieving water self locking. The quick connector comprises a top plug A, an expansion spring A, a water nozzle female end, a top plug B, an expansion spring B and a water nozzle male end, wherein one end of the water nozzle female end is connected with a water pipe connector A; an external nut A is screwed at the outer part of the water nozzlefemale end in a threaded manner; a baffle ring is arranged on an inner cavity of the water nozzle female end; the transversely placed T-shaped top plug A is arranged in the baffle ring; one end of thetop plug A is arranged in the baffle ring; the other end of the top plug A is arranged in an inner circle of the water nozzle female end; and the top plug B is arranged in the water nozzle male end.The quick connector has the beneficial effects that the expansion springs in opposite positions are arranged, the top plug A and the top plug B are relatively separated during socket connection, a water way is sealed when the top plug A and the top plug B are separated, and a self locking function is achieved; the integral structure is simple, and reliability is high; and the situation that internal instruments are damaged due to water leakage when a handle is inserted and pulled can be effectively prevented, the risk of short circuit of the instruments is reduced, the failure rate of the instruments is decreased, and the service life of the instruments is prolonged.

Description

technical field [0001] The invention relates to a pipeline connection device for a cosmetic instrument, in particular to a self-locking water quick connector. Background technique [0002] A quick connector is a connector that can be connected or disconnected without tools. Quick connectors can be divided into: quick connectors for air, quick connectors for oxygen fuel gas, quick connectors for gas and liquid, quick connectors for oil pressure, quick connectors for inert gas, quick connectors for cooling water and oil, and semiconductor quick connectors. Convenient and widely welcomed by all kinds of enterprises. [0003] There are a large number of lines in the beauty instrument and the operating handle, as well as the waterway. When the handle is disassembled, because the joint of the waterway does not have a self-locking function, the water in the waterway will flow from the waterway connector when the handle is removed. Leak out, cause circuit short circuit, instrument...

Problems solved by technology

[0003] There are a large number of lines in the beauty instrument and the operating handle, as well as the waterway. When the handle is disassembled, because the joint of the waterway does not have a self-locking function, the water in the waterway will flow from the waterway connector when the handle is removed. If it leaks out, it will cause a short circuit in the circuit, damage the instrument, cause property loss, and also pose a serious safety hazard.
