Technical Field

[0001] The utility model relates to the technical field of faucets, in particular to a water-leakage-proof split faucet. Background Art

[0002] A split faucet generally includes a shell, a valve core tube and a valve core. A water outlet is provided on the shell, and the water outlet is connected to the water outlet pipe of the valve core tube, so as to transport the fluid out. However, there will inevitably be a gap between the valve core tube and the shell, which can easily cause the fluid to leak from the gap, resulting in a waste of resources and a bad experience for users. Utility Model Content

[0003] Therefore, in view of the above-mentioned problems, the utility model provides a leak-proof water-dividing faucet.

[0004] To achieve the above-mentioned purpose, the technical solution of the utility model is to provide a leak-proof water-dividing faucet, including a shell, a water outlet channel arranged in the shell, a water outlet opened on the shell, and a valve core tube arranged in the shell, the valve core tube including: a valve seat, a water inlet pipe and a water outlet pipe arranged at the bottom of the valve seat, the water outlet pipe is connected with the water outlet channel, a sealing ring groove is opened on the circumference of the water outlet pipe, a sealing ring is arranged in the sealing ring groove, and a deformation ring is arranged on the inner side of the sealing ring for deforming and pressing against the shell when impacted by fluid.

[0005] A further improvement is that a deformation groove for increasing the deflection amount of the deformation ring is provided on the inner side of the sealing ring.

[0006] A further improvement is that a guide strip is provided on the inner side of the sealing ring groove on the valve seat to allow the fluid to flow more smoothly into the space between the deforming ring and the valve core tube.

[0007] A further improvement is that a limiting ring is provided on the shell for resisting the valve seat of the valve core tube, a positioning plate is provided at the bottom of the water inlet pipe, and a base is provided at the bottom of the shell for resisting the positioning plate.

[0008] A further improvement is that: the limiting ring platform is also provided with a mounting thread for mounting a valve core gland.

[0009] A further improvement is that a rotation-stopping device for preventing the valve core tube from rotating is also provided between the valve core tube and the housing.

[0010] A further improvement is that the anti-rotation device comprises a clamping block arranged on the valve core tube and a clamping groove opened on the shell body for clamping with the clamping block.

[0011] A further improvement is that the shell is a plastic shell or a zinc alloy shell.

[0012] A further improvement is that the water inlet pipe comprises a cold water inlet pipe and a hot water inlet pipe.

[0013] The advantages and beneficial effects of the utility model are:

[0014] The structure is simple, the installation is convenient, and the sealing is strong. A deformation ring is arranged on the sealing ring, which can be further close to the shell under the impact of the fluid to enhance the sealing. A deformation groove is also provided on the sealing ring. On the one hand, the deformation ring can be more closely fitted to the curved shell when impacted by the fluid. On the other hand, the sealing ring close to the sealing ring groove can be closer to the sealing ring groove under the pressure of the fluid, thereby greatly enhancing the sealing between the shell and the valve core tube.

DETAILED DESCRIPTION

[0022] The following is a further description of the specific implementation of the present invention in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0023] like Figure 1-Figure 6As shown, a leak-proof water splitter faucet comprises a shell 1, a water outlet channel 2 arranged in the shell 1, a water outlet 3 opened on the shell 1, and a valve core tube 4 arranged in the shell 1, wherein the valve core tube 4 comprises: a valve seat 5, a water inlet pipe 6 and a water outlet pipe 7 arranged at the bottom of the valve seat 5, wherein the water outlet pipe 7 is connected with the water outlet channel 2, a sealing ring groove 8 is opened on the circumference of the water outlet pipe 7, a sealing ring 9 is arranged in the sealing ring groove 8, and a deformation ring 10 is arranged inside the sealing ring 9 for deforming and pressing against the shell 1 when impacted by fluid;

[0024] Since the sealing ring 9 has a certain elasticity, when the sealing ring 9 is installed in the sealing ring groove 8, the end of the sealing ring 9 protrudes out of the sealing ring groove 8, and the deformation ring 10 is located on the inner side of the protruding part of the sealing ring 9.

[0025] In order to allow the deformable ring 10 to deflect to a greater distance when impacted by fluid, thereby being close to the housing 1 and preventing water leakage, a deformation groove 12 for further enhancing the deflection amount of the deformable ring 10 is provided on the inner side of the sealing ring 9 .

[0026] The sealing ring 9 can be: a silicone sealing ring 9, a rubber sealing ring 9, etc.

[0027] In order to allow the fluid to flow better between the deforming ring 10 and the valve core tube 4 and thus push the deforming ring better, a guide strip 11 is provided on the inner side of the sealing ring groove 8 on the valve seat 5 to allow the fluid to flow more smoothly between the deforming ring 10 and the valve core tube 4.

[0028] In order to facilitate the fixing of the valve core tube 4, a limiting ring 13 for resisting the valve seat 5 of the valve core tube 4 is provided on the shell 1, a positioning plate 14 is provided at the bottom of the water inlet pipe 6, and a base 15 resisting the positioning plate 14 is locked at the bottom of the shell 1.

[0029] In order to facilitate the installation of the valve core, the limiting ring platform 13 is also provided with an installation thread 16 for installing the valve core gland.

[0030] In order to prevent the valve core tube 4 from rotating inside the housing 1, a rotation-stopping device for preventing the valve core tube 4 from rotating is also provided between the valve core tube 4 and the housing 1, and the rotation-stopping device comprises: a clamping block 17 provided on the valve core tube 4, and a clamping groove 18 provided on the housing 1 for clamping with the clamping block;

[0031] The engaging block 17 is located on the top of the valve seat 5 , and the engaging groove 18 is formed on the connecting thread.

[0032] In order to enhance the strength of the shell 1 and to make it easier for consumers to choose, the shell 1 is a plastic shell 1 or a zinc alloy shell 1 .

[0033] In order to enhance the functionality of the faucet, the water inlet pipe 6 includes: a cold water inlet pipe 6 and a hot water inlet pipe 6 .

[0034] Working principle: During installation, install the sealing ring 9 in the sealing ring 9 groove 8, with one end of the deformation ring 10 located on the side close to the water outlet channel 2, then align the snap-fit ​​block 17 and the snap-fit ​​groove 18, install the valve core tube 4 into the housing 1, then install the base 15 to fix the valve core tube 4, and finally place the valve core into the valve seat 5 and position the valve core gland by installing the thread 16 to complete the assembly;

[0035] When in use, the fluid flows into the valve core through the water inlet pipe 6 and then into the water outlet pipe 7. When the fluid flows through the connection between the water outlet pipe 7 and the water outlet channel 2, the fluid will generate a certain impact force on the deformation ring 10, making it fit more closely on the shell 1, thereby preventing the fluid from leaking from the side close to the shell 1. A deformation groove 12 is also provided, which allows the fluid to flow in and generate pressure on the sealing rings 9 on both sides, so that the bottom of the sealing ring 9 is closer to the sealing ring groove 8, thereby enhancing the sealing performance.

[0036] The basic principles, main features and advantages of the utility model are shown and described above. Those skilled in the art should understand that the utility model is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which shall fall within the scope of the utility model to be protected.
