Description

Technical Field

[0001] The utility model relates to the technical field of faucet rotating cores, in particular to a rotating core used for a faucet water outlet pipe. Background Art

[0002] The faucet is a common name for a water valve, which is used to control the size of the water flow switch. It has the effect of saving water and is often used in daily life. Among them, the elbow faucet is widely used and is mainly arranged next to the sink. The elbow faucet includes a valve body and a water outlet elbow that can be rotated on the valve body. The user can rotate the water outlet elbow according to different needs, which is convenient for the user to use. The structure for realizing the rotation of the water outlet elbow on the valve body is a rotating core installed between the water outlet elbow and the valve body. The existing rotating core is mainly divided into a core body and a core sleeve. When the core sleeve rotates along the surface of the core body, the water outlet elbow can be rotated. However, the structure of some existing rotating cores is relatively simple, and there is no limiting structure inside it, which is not easy to realize the function of effectively limiting the core sleeve and the core body. When the rotating core is used for a long time, the core sleeve and the core body are prone to loosening, causing the water outlet elbow to shake or get stuck when driving the core sleeve to rotate.

[0012] (3) Beneficial effects

[0013] Compared with the prior art, the present invention provides a rotating core for a faucet outlet pipe, which has the following beneficial effects:

[0014] 1. The rotating core used in the water outlet pipe of the faucet cooperates with each other between the limit groove and the limit ring, so that the upper surface of the block and the lower surface of the core sleeve are respectively tightly attached to the inner wall of the top of the limit groove and the upper surface of the limit ring. The cooperation between several groups of structures can firmly fix the core sleeve on the outside of the core body, realizing the function of effectively limiting the core sleeve and the core body, preventing the core sleeve and the core body from loosening easily, and preventing the water outlet elbow from shaking or getting stuck when driving the core sleeve to rotate.

[0015] 2. The rotating core used in the faucet outlet pipe allows tap water to enter the interior of the shell through the water inlet groove and the water inlet, and then is filtered by the four groups of filter structures from bottom to top. Finally, the filtered tap water is discharged through the water outlet.

[0026] The inner wall of the core 1 is in active contact with an anti-slip layer 101, and the inner wall of the anti-slip layer 101 is fixedly connected to the outer shell 102. The outer side of the lower surface of the outer shell 102 is provided with a water inlet groove 103, and the top of the inner wall of the water inlet groove 103 is provided with a water inlet 104. The inner part of the outer shell 102 is provided with a dust collecting groove 105, and the water inlet 104 is connected to the dust collecting groove 105. The inner part of the outer shell 102 is arranged from bottom to top with a primary filter layer 106, an adsorption layer 107, a sterilization layer 108 and The secondary filter layer 109 and the top of the inner wall of the outer shell 102 are provided with an internal thread 110, and the upper surface of the outer shell 102 is movably connected with a top cover 111, and the lower surface of the top cover 111 is tightly attached to the upper surface of the secondary filter layer 109, and the outer surface of the top cover 111 is provided with an external thread 112, and the external thread 112 is threadedly connected to the internal thread 110, and the upper surface of the top cover 111 is provided with a water outlet 113 which passes through from top to bottom, and a hand buckle 114 is fixed to the middle of the upper surface of the top cover 111.

[0027] The rotating core used in the water outlet pipe of the faucet cooperates with each other between the limiting groove 4 and the limiting ring 5, so that the upper surface of the block 9 and the lower surface of the core sleeve 6 are respectively tightly attached to the inner wall of the top of the limiting groove 4 and the upper surface of the limiting ring 5. The cooperation between several groups of structures can firmly fix the core sleeve 6 on the outside of the core body 1, realizing the function of effectively limiting the core sleeve 6 and the core body 1, preventing the core sleeve 6 and the core body 1 from loosening easily, and preventing the water outlet elbow from shaking or getting stuck when driving the core sleeve 6 to rotate.

[0028] The sizes and shapes of all components in this structure are not specifically limited here and need to be produced according to actual conditions.

[0029] In order to prevent the protrusion 8 from being broken or damaged due to the influence of external forces alone for a long time, the utility model has anti-slip strips 10 fixed to the top and bottom of the outer surface of the core sleeve 6. The number of anti-slip strips 10 is set to several groups. Several groups of anti-slip strips 10 increase the contact points between the core sleeve 6 and the faucet water outlet pipe. At the same time, the anti-slip strips 10 can increase the friction. Therefore, when the faucet water outlet pipe drives the core sleeve 6 to rotate through the protrusion 8, because the contact points are increased, the force points will also increase accordingly, preventing all external forces from acting on the protrusion 8, preventing the protrusion 8 from being broken or damaged due to the influence of external forces alone for a long time, and indirectly extending the service life of the protrusion 8.

[0030] In order to facilitate the staff to control the tool to screw the core body 1, the utility model provides a vertical section 11 on the top of the outer surface of the core body 1. The number of the vertical sections 11 is set to six groups. The six groups of vertical sections 11 form the shape of a bolt cap. Therefore, it is convenient for the staff to control the specified tool, such as a wrench or the like, to screw the core body 1.

[0031] In order to facilitate the staff to install the device inside the faucet, the utility model provides a connecting thread 12 at the bottom of the outer surface of the core body 1. Due to the setting of the connecting thread 12, the staff can threadably connect the core body 1 with the valve body inside the faucet. This process is simple to operate, saves time and effort, and facilitates the staff to install the device inside the faucet.

[0032] In order to extend the service life of the core body 1, the core sleeve 6, the protrusion 8 and the clamping block 9, the utility model sets the core body 1, the core sleeve 6, the protrusion 8 and the clamping block 9 to be made of stainless steel. Stainless steel has a high hardness and is not easy to deform, thereby extending the service life of the core body 1, the core sleeve 6, the protrusion 8 and the clamping block 9.

[0033] The electrical components mentioned in this article are all connected to an external main controller and 220V AC power, and the main controller can be a conventional known device that performs control such as a computer.

[0034] When in use, the staff first installs the device inside the elbow faucet so that it is located between the water outlet elbow and the valve body, so that the core body 1 is threadedly connected to the valve body through the connecting thread 12, and at the same time, the protrusion 8 is inserted into the through hole opened on the inner wall of the water outlet elbow to fix the water outlet elbow and the core sleeve 6. Because of the arrangement of the six groups of vertical sections 11, it is convenient for the staff to twist the core body 1 and to disassemble and assemble the core body 1 and the valve body. After installation, when the user uses it, controlling the water outlet elbow can drive the through hole, protrusion 8 and core sleeve 6 to rotate. At the same time, due to the arrangement of the anti-slip strip 10, the contact points between the core sleeve 6 and the inner wall of the water outlet elbow are increased, the friction force is increased, and the external force exerted on the protrusion 8 can be effectively dispersed. At the same time, the core sleeve 6 can rotate along the surface of the core body 1 to realize the rotation of the new water outlet elbow. During this process, the lower surface of the core sleeve 6 is tightly attached to the upper surface of the limiting ring 5 for rotation. At the same time, the core sleeve 6 drives the clamping block 9 to rotate along the inside of the limiting groove 4, so that the upper surface of the clamping block 9 is tightly attached to the inner wall of the top of the limiting groove 4 for rotation, thereby effectively limiting the rotating core sleeve 6, ensuring the stability of the core sleeve 6 during rotation, and also ensuring the stability of the water outlet elbow during rotation. At the same time, because a sealing ring 3 is provided between the core body 1 and the core sleeve 6, the core sleeve 6 is smoother and more flexible when rotating, which makes the user feel better and the experience better. When the water valve is opened, tap water will pass through the water inlet trough 103 and the water inlet 104 from bottom to top. 101 is pulled out of the inner part of the core 102, and then the hand buckle 114 is controlled to drive the top cover 111 and the external thread 112 to rotate counterclockwise. The top cover 111 can be rotated upward out of the shell 102 so that the top cover 111 releases the shielding of the shell 102. Then the staff can pour out the primary filter layer 106, adsorption layer 107, sterilization layer 108 and secondary filter layer 109 that have become dirty after long-term use, and then rinse the impurities remaining in the shell 102 and the dust collecting tank 105. Then replace them with new ones in order, and then screw the top cover 111 back into the shell 102 to shield its interior again. Then, the shell 102 and the anti-skid layer 101 are pressed into the interior of the core 1 again. Because the setting of the anti-skid layer 101 can indirectly increase the friction between the shell 102 and the inner wall of the core 1, therefore, without the action of manpower,It will not fall out of the core 1 on its own, and has good stability. The user then installs the water outlet elbow between the valve body. At this point, the replacement of the primary filter layer 106, adsorption layer 107, sterilization layer 108 and secondary filter layer 109 is completed to prevent clogging.

[0035] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
