Detailed Implementation

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] Please see Figures 1-8 This utility model provides a technical solution: an idler valve core, including a housing 2, a circular through-hole dial 10, an upper ceramic plate 12, a lower ceramic plate 14, and a base 17. A circular shell 4 is installed above the housing 2, and a rotating disk 1 is rotatably installed inside the circular shell 4. A guide groove 3 is provided through the center of the rotating disk 1, and a handle 7 is slidably installed inside the guide groove 3. Springs 24 are installed at the lower left and right ends of the handle 7, and the lower ends of the two springs 24 are respectively connected to the rotating disk 1. The lower end of the housing 2 is provided with multiple side grooves 6, and the housing 2 is annular. The side is provided with multiple rectangular slots 5, the rotor 9 is fixedly connected above the circular through-hole dial 10, multiple protrusions 11 are fixedly connected to the lower side of the circular through-hole dial 10, multiple slots 13 are provided above the upper ceramic plate 12, multiple first water passage holes 15 are provided through the upper part of the lower ceramic plate 14, and multiple plastic flexible hook plates 20 and multiple clamping plates 21 are fixedly connected to the upper side of the base 17. This design solves the problem that most idling valve cores have complex internal structures and are inconvenient to disassemble the outer shell, which leads to slow and inefficient maintenance or replacement of internal parts.

[0024] As the first embodiment of this utility model: the base 17 has an outer groove 18 on its annular side, and an outer sealing ring 23 is installed inside the outer groove 18. Multiple second water passage holes 22 are provided through the top of the base 17. An inner groove 19 is provided above the base 17, and an inner sealing ring 16 is installed inside the inner groove 19. The outer sealing ring 23 and the inner sealing ring 16 are used to improve the overall sealing performance of the device. The multiple second water passage holes 22 are provided to match the multiple first water passage holes 15. A pin 8 is inserted into the round hole on the left side of the rotor 9. A groove matching the lower end of the handle 7 is provided in the middle of the inner bottom surface of the rotor 9. The rotor 9 is rotatably installed inside the outer casing 2. The pin 8 is used to limit the position of the handle 7. The upper ceramic plate 12 and the circular through-hole dial 10 are engaged with multiple slots 13 and multiple protrusions 11. A circular drain hole is provided through the upper ceramic plate 12. The upper ceramic plate 12 is placed on top of the lower ceramic plate 14, and the lower ceramic plate 14 is connected to the base 17 below. The circular drain hole facilitates cooperation with multiple first water passages 15 to supply water. A circular hole is provided on the front side of the handle 7 for the pin 8 to pass through. The outer shell 2 and the base 17 are fastened with multiple flexible plastic hook plates 20 and multiple rectangular slots 5.

[0025] As a second embodiment of this utility model: When it is necessary to disassemble the outer shell 2, multiple plastic flexible hook plates 20 are squeezed inward to deform the plastic flexible hook plates 20, thereby causing the hook part of the plastic flexible hook plate 20 to disengage from the rectangular slot 5, so that the outer shell 2 can be disassembled. When it is necessary to adjust the angle of the upper ceramic plate 12, first pull out the pin 8, then press the handle 7, so that the handle 7 moves down along the guide groove 3, thereby causing the two springs 24 to be compressed, so that the lower end of the handle 7 aligns with the groove in the middle of the inner bottom surface of the rotor 9. Then insert the pin 8 and pass through the handle 7, so that the handle 7 can be rotated to drive the rotor 9 to rotate. The rotor 9 drives the circular through-hole dial 10 to rotate, and the circular through-hole dial 10 drives the upper ceramic plate 12 to rotate, thereby adjusting the angle of the upper ceramic plate 12, thereby realizing the discharge of water. The water will pass through multiple second water holes 22, multiple first water holes 15, the circular drain hole above the upper ceramic plate 12, and the circular through hole above the circular through-hole dial 10, thereby being discharged.
