Description

Technical Field

[0001] The utility model relates to the technical field of valve cores, in particular to a faucet valve core structure. Background Art

[0002] The valve core is one of the important parts of the control components in fluid systems such as faucets and valves. The valve core is a valve part that realizes the basic functions of direction control, pressure control or flow control by means of its movement. The existing ceramic valve core is composed of a ceramic static plate, a ceramic moving plate and a valve core housing. The water inlet and outlet are arranged on the ceramic plate, and the opening and closing of the valve are realized by the relative alignment and misalignment of the holes on the ceramic moving plate.

[0003] The publication number CN216279679U discloses a faucet valve core, which is characterized in that: it includes a valve core and a housing installed outside the valve core; the sealing ring in the groove abuts against the housing to cut off the water source from flowing to the valve stem. By the above method, the water source and the valve stem do not contact each other, so the problem of heavy metal pollution of the water source caused by the contact between the valve stem and the water source is solved. At the same time, the installation of the sealing ring and the processing of the groove are simple and convenient, and thus the processing cost of the device can be reduced. At the same time, the setting of the connecting part can also reduce the overall length of the valve stem, so as to reduce the cost brought by using a valve stem made of metal material.

[0004] However, the above technical solution has the following problems: when using this valve core to control the opening and closing and flow rate of hot water, a certain amount of theophylline will be left on the valve core and accumulate on it when the hot water flows through the valve core, making it difficult for workers to remove the valve core when replacing a new one. Summary of the Utility Model

Detailed implementation mode

[0021] Embodiment 1

[0022] As Figures 1-4 shown, a faucet valve core structure proposed in this embodiment includes a valve core housing 1 and a sealing ring 9. The bottom of the valve core housing 1 is threadedly connected to a fixing disc 8. A water passing disc 7 is placed on the fixing disc 8. A selection disc 6 is slidably connected to the top end of the water passing disc 7. An adjusting frame 5 is clamped to the top end of the selection disc 6. An adjusting disc 4 is rotatably arranged on the adjusting frame 5. An adjusting rod 3 is arranged on the adjusting disc 4. An adjusting frame 2 is arranged on the valve core housing 1. The adjusting rod 3 is rotatably connected to the adjusting frame. The outer peripheral surface of the valve core housing 1 has threads; the sealing ring 9 is arranged on the outer peripheral surface of the valve core housing 1, and the sealing ring 9 is located below the threads.

[0023] When this embodiment is used, the worker threadedly connects the valve core into the faucet. The sealing ring 9 abuts against the valve core housing 1 and the inner wall of the faucet. When the user uses the water flow, part of the water flow flows along the gap to between the faucet and the valve core housing 1. The sealing ring 9 blocks the water flow, thereby preventing scale from accumulating on the threads of the outer peripheral surface of the valve core housing 1, thereby reducing the difficulty of replacing the valve core. The user pushes the faucet, the faucet drives the adjusting rod 3 to rotate, the adjusting rod 3 drives the adjusting frame 5 to move, the water flow passes through the fixing disc 8 and the water passing disc 7, and the flow rate and outflow temperature of the water flowing out of the faucet are adjusted according to the position of the selection disc 6 driven by the adjusting frame 5, so as to improve the versatility of the faucet.

[0024] Embodiment 2

[0025] As Figures 2-4 shown, a faucet valve core structure proposed in this embodiment, compared with Embodiment 1, in this embodiment, the fixing disc 8 includes a fixing disc part 83, a fixing ring part 82 arranged at the top end of the fixing disc part 83, and a plurality of positioning block parts 81 arranged along the ring above the fixing disc part 83. The bottom of the water passing disc 7 has a plurality of positioning grooves 71 arranged along the ring, and the plurality of positioning grooves 71 are respectively and correspondingly clamped with the plurality of positioning block parts 81.

[0026] Both the fixing disc 8 and the water passing disc 7 are provided with cold water holes, hot water holes and water outlet holes, and the two cold water holes, hot water holes and water outlet holes are respectively and correspondingly communicated. The outer peripheral surface of the fixing ring part 82 has threads, the height of the fixing ring part 82 is less than the thickness of the water passing disc 7, and the bottom of the water passing disc 7 has an adjusting groove 61, and the adjusting groove 61 is communicated with the cold water hole, the hot water hole and the water outlet hole.

[0027] During the use of this embodiment, warm water and cold water flow mixed into the inside of the valve core. The water passing disc 7 blocks the connection between the water flow and the fixed disc 8 and the valve core shell 1, thus preventing water scale from remaining at the connection, reducing the difficulty for workers to maintain the faucet. And workers can adjust the water outlet temperature and water outlet flow rate of the faucet by adjusting the connection area between the adjusting groove 61 and the cold water hole and the hot water hole, thereby improving the versatility of the faucet.

The axis of the threaded hole 33 is perpendicular to the axes of the moving channel 31 and the axial hole 32 in the horizontal plane. The moving channel 31 is composed of a rectangular hole and two circular holes. The two circular holes are respectively located at both ends of the rectangular hole, and the diameters of the circular holes are the same as the diameter of the rectangular hole. The adjusting frame 5 has a rotating shaft, and the diameter of the rotating shaft is the same as the diameter of the circular hole. The rotating shaft is located in the moving channel 31.

During the rotation of the adjusting rod 3, the rotating shaft gradually descends in the moving channel 31 until it abuts against the bottom of the moving channel 31. At the same time, water flows out of the faucet. And the adjusting rod 3 can use steel as the bone and plastic as the flesh, so as to ensure the service life of the adjusting rod 3 while reducing the cost of the valve core.
