Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 1, a washing machine faucet 13 in the prior art is directly connected with a hose 4 through a fixed connector 14, water is injected into the washing machine, the washing machine faucet 13 is in a normally open state, but due to factors such as pressure change of a waterway, aging of the hose 4, and environmental temperature change of the washing machine, the hose 4 is easy to fall off from the washing machine faucet 13, and after the hose 4 is separated, water flows to the ground, so that waste of water resources is caused while the ground is soaked, and a huge potential safety hazard exists.

The invention relates to a washing machine tap water-stopping device as shown in figures 2 to 4, which comprises a hollow joint 1, a mandrel 2 sleeved in the hollow joint 1, the reset spring that the cover was located outside dabber 2 and with the hose 4 of hollow joint 1 lower extreme intercommunication, the upper end of hollow joint 1 is seted up the water inlet with washing machine tap 13 intercommunication, the lower extreme of hollow joint 2 is seted up the delivery port with washing machine intercommunication, the upper end of dabber 2 is equipped with the piston head 5 of control hollow joint 1 break-make, the lower extreme of dabber 2 is equipped with guide block 6, the passageway that supplies rivers to pass through is seted up to guide block 6 periphery wall, hose 4 includes hollow body 7 and locates the connector 8 of hollow body 7 inlet end, 8 covers of connector are located outside the hollow joint 1, the connector 8 is equipped with a connection platform 9 with the link of hollow body 7, connection platform 9 supports and presses in the lower extreme of dabber 2. During normal work, after installing hose 4, connection platform 9 on hose 4 jacks up dabber 2, and piston head 5 breaks away from the contact with hollow joint 1, and the water route is put through, and rivers flow out from the passageway, and after hose 4 drops, hose 4 breaks away from the contact with dabber 2, receives reset spring 3's thrust effect, and dabber 5 moves down, and piston head 5 and hollow joint 1 recontact block the water route. Set up piston head 5 through dabber 2 upper end, realize when hose 4 breaks away from, under reset spring 3's reset action, piston head 5 and hollow joint 1 contact block the water route automatically, prevent the function on rivers ground, improved washing machine tap 13's safety in utilization to watertight fittings's simple structure, low in production cost.

The inner wall of the hollow joint 1 is provided with a flow restriction opening 10, and the piston head 5 runs up and down inside and outside the flow restriction opening 10. The flow restriction opening 10 is an annular boss arranged on the inner wall of the hollow joint 1, and the inner diameter of the annular boss is matched with the outer diameter of the piston head 5.

The piston head 5 is a waterproof ring sleeved on the mandrel 2. The waterproof ring is made of nitrile rubber or silica gel, and the nitrile rubber or silica gel is more beneficial to sealing and waterproofing between the waterproof ring and the hollow joint 1.

The inner wall of the water inlet is provided with internal threads, the water outlet part of the water outlet nozzle of the washing machine faucet is provided with external threads, and the hollow joint 1 is in threaded connection with the water outlet part of the water outlet nozzle of the washing machine faucet 13.

The return spring 3 is a reducing spring. The outer diameter of the reducing spring is gradually reduced from top to bottom, the elasticity of the spring is relatively small, and the pressure cannot expand the hose 4 to make the hose 4 fall off when the hose is used.

The peripheral wall of the hollow joint 1 is provided with an annular groove 11, and the arrangement of the annular groove 11 is beneficial to increasing the contact friction force between the hollow joint 1 and the water outlet hose 4 and preventing the hollow joint from falling off.

A waterproof gasket 12 is arranged in the water inlet, the waterproof gasket 12 is made of nitrile rubber or silica gel, the waterproof gasket 12 is tightly pressed on a water outlet part of a water outlet nozzle 13 of the washing machine faucet to seal and prevent water, and the waterproof gasket 12 is made of nitrile rubber or silica gel, so that the waterproof between the washing machine faucet and the hollow joint 1 is facilitated.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
