[0032] The fixing device is a threaded top block 15 threadedly connected to the upper end face of the faucet housing 1 inside the installation inner cavity 2, and an avoidance opening 16 is penetrated through the middle of the threaded top block 15.

[0033] A sealing washer 17 is provided on the upper end surface of the mounting base 6 at the end of the water outlet 12. When the mounting base 6 is pressed tightly against the limiting boss 3, the sealing washer 17 is used to seal the gap between the water outlet 12 and the limiting boss 3. The sealing washer 17 is a rubber washer. The thickness or height of the sealing washer 17 can be selected according to the shape of the product or the distance between the mounting base 6 and the limiting boss 3 to adapt to different usage situations.

[0034] At least one positioning jack 18 is provided on the upper end surface of the valve core tube body 7, and at least one positioning plug (not shown in the figure) is provided at the lower end of the control valve core 13. The positioning plug (not shown in the figure) is in clearance fit with the positioning jack 18.

The diameter of the circumferential top plate 22 is larger than the diameter of the water storage cavity 10.

[0038] The working principle of the present utility model: When assembling the faucet, the valve core tube body 7 is driven to insert the mounting base 6 into the installation inner cavity 2 from the lower end of the faucet housing 1. Observe the position of the mounting base 6 through the opening at the upper end of the faucet housing 1 until the limiting boss 3 abuts against the upper end of the mounting base 6, and make the position of the water outlet 12 correspond to the water outlet channel 4. Then, put the threaded block 14 into the lower end of the faucet housing 1 and twist it to push the valve core tube body 7 to drive the mounting base 6 to be pressed tightly against the limiting boss 3. At this time, install the control valve core 13 on the valve core body in the placement cavity 8. Then, put the threaded top block 15 into the upper end of the faucet housing 1 and twist it to press the control valve core 13 tightly against the valve core tube body 7. The assembly process is relatively simple and can speed up the assembly speed of the faucet;

[0039] When discharging water, the water flow enters through the water inlet opening 9, passes through the water inlet channel 23 and enters the control valve core 13 in the placement cavity 8. The water flow enters the water storage cavity 10 from the control valve core 13 into the communication channel 11. When the water flow in the water storage cavity 10 gradually accumulates, it flows out to the water outlet channel 4 through the water outlet 12, and then the water flow is discharged outwards from the water outlet nozzle 5;

[0040] When installing the control valve core 13 on the upper end face of the valve core tube body 7, the position of the control valve core 13 corresponds to the water inlet channel 23 and the communication channel 11 of the valve core tube through the positions of the positioning insertion rod (not shown in the figure) and the positioning insertion hole 18;

[0041] When pushing the valve core tube body 7 to drive the mounting seat 6 to abut against the limiting boss 3, if the position of the limiting boss 3 does not correspond to the position of the water outlet 12, rotate the valve core tube body 7 to drive the mounting seat 6 to rotate circumferentially until the limiting boss 3 is stuck at the position of the positioning boss 20. The position of the mounting seat 6 is restricted through the cooperation of the positioning boss 20 and the limiting boss 3, which can accelerate the positioning speed of the water outlet 12 and the limiting boss 3;

[0042] When the threaded block 14 pushes the valve core tube body 7 to drive the mounting seat 6 to rise, as the valve core tube body 7 gradually rises, the sealing gasket 17 is gradually squeezed between the water outlet 12 and the limiting boss 3, thereby improving the sealing effect between the water outlet 12 and the water outlet channel 4.
