  • the sealing member cooperates with the inner wall of the water flow passage to control the water flow. Therefore, the inner wall of the water flow passage which is in sealing contact with the blocking member protrudes inwardly to form a water outlet which is smaller than the inner diameter of the water flow passage.
  • a sealing groove is arranged at one end of the sealing member facing the water outlet, and a sealing ring is sleeved on the sealing groove.
  • the diameter of the sealing member above the sealing ring is slightly larger than the diameter of the sealing member under the sealing ring.
  • the sealing ring sleeved at one end of the sealing member is in sealing contact with the matching inclined surface of the water flow passage, and at the same time, the limiting platform above the inclined surface is matched with the lower end surface of the guiding rib of the blocking member, and the sealing is restricted.
  • the blocking piece moves excessively downwards.
  • the sealing ring is excessively pressed to cause the seal to fail.
  • the embodiment provides a washing machine, comprising an inlet pipe and a water inlet pipe joint 3 of the washing machine.
  • the water inlet pipe of the washing machine is installed on the washing machine faucet through a water inlet pipe joint, and a sealing member is arranged in the water outlet of the washing machine faucet.
  • One end of the top column is disposed in the joint of the water inlet pipe.
  • the joint of the inlet pipe includes a joint pipe 302 and a lock sleeve 301.
  • the lock sleeve 301 can move up and down with respect to the joint pipe 302, and can be locked by the self-locking spring 303, and the limit ring prevents the lock sleeve and the joint pipe from falling off. Specifically, it can be described as follows:
  • the lock sleeve that receives the water tap is active, and there are N balls inside to fix the lock, when the external force is applied downward.
  • the unlocking chamfer structure of the faucet squeezes the ball and gradually moves outward.
  • the ball is squeezed into the unlocking groove, and the ball can not be inserted into the groove of the water head, so that the faucet of the lower connecting pipe can be easily pulled out. .
  • the top pillar 10 is pre-installed inside the water inlet pipe joint of the present embodiment, and the flow channel groove 1003 is provided around the base of the top pillar.
  • the top column of the inlet pipe naturally opens the blocking member and compresses the spring.
  • the handle of the faucet is rotated by 90°, the water flow can enter the water outlet through the body, and then enter the washing machine inlet pipe through the water outlet of the faucet, and the water flows into the washing machine.
  • the top column is preferably injection molded integrally with the inlet pipe joint.
  • the top post can also be a single component that is secured in the faucet joint.
  • the faucet supplies water to the inlet pipe to form a water flow passage.
  • the sealing member inside the faucet seals the water outlet of the faucet. Even if the valve core is opened in the faucet, the water cannot flow out from the water outlet, which greatly protects the property of the consumer.

Abstract

La présente invention concerne un robinet de machine à laver. Le robinet comprend un corps (1) et une tête de sortie d'eau (2) raccordée au corps (1), l'intérieur de la tête de sortie d'eau (2) étant un canal d'écoulement d'eau en communication avec le corps (1), et comprend en outre un élément de blocage (9) et une tige de poussée (10) disposés de manière séparée, l'élément de blocage (9) étant disposé dans le canal d'écoulement d'eau et coopérant avec une sortie d'eau (202) de la tête de sortie d'eau (2) pour bloquer le canal d'écoulement d'eau, et une extrémité de la tige de poussée (10) s'étend dans la tête de sortie d'eau (2) depuis l'extérieur à travers la sortie d'eau (202) de la tête de sortie d'eau (2) et coopère avec l'élément de blocage (9) pour pousser l'élément de blocage (9) vers le haut de façon à débloquer le canal d'écoulement d'eau. Du fait que l'élément de blocage (9) et la tige de poussée (10) sont séparés, le robinet de machine à laver peut permettre au robinet de couper automatiquement l'alimentation en eau lorsqu'un tuyau d'entrée de l'eau de la machine à laver est désolidarisé, ce qui empêche un problème de grave fuite d'eau. La tige de poussée (10) est agencée ou montée indépendamment dans le tuyau d'entrée pour empêcher une exposition à l'extérieur du robinet, ce qui facilite l'emballage et le transport, réduit les collisions et les dommages, et facilite également le remplacement des composants et des pièces.
