[0032] The bottom of the valve core body 1 is provided with a middle water outlet 107 communicating with the first water outlet channel 101 , and the bottom of the valve core body 1 is provided with a peripheral water outlet 108 communicating with the second water outlet channel 103 .

[0033] The middle water outlet 107 is a plurality of mesh-like spaced holes arranged around the spring positioning protrusion 106 .

[0034] The peripheral water outlets 108 are two symmetrical arc-shaped strip holes arranged at the periphery of the bottom of the valve core body 1 .

[0035] The water inlet channels 102 are two channels symmetrically arranged outside the valve core body 1 and axially arranged along the valve core body 1 .

[0036] The second water outlet channels 103 are two channels symmetrically arranged outside the valve core body 1 and axially arranged along the valve core body 1 .

[0037] An outer sealing rubber ring 10 is sleeved on the outer peripheral wall of the valve core body 1 , and a valve core cover sealing ring 11 is sleeved on the outer peripheral wall of the valve core cover 2 , which is beneficial to waterproofing of the valve core body 1 and the valve core cover 2 after installation.

[0041] Working process: In the initial state, the upper part of the pull rod hook 8 is in the closed gear 7031. At this time, the water entering the first water outlet channel 101 is blocked by the second water separation seal ring 5 and the third water separation seal ring 6, and the water cannot flow out of the first water outlet channel 101 and flow into the second water outlet channel 103. The bouncing core 7 is pressed. Since the height of the fourth partition area 7037 and the fifth partition area 7038 adjacent to each other is higher than the height of the fifth partition area 7038 and the fourth partition area 7037 adjacent to each other, the upper part of the pull rod hook 8 cannot slide backwards. The upper part of the pull rod hook 8 slides from the fifth partition area 7038 to the first partition area 7034, and the bouncing core 7 is released. Since the first partition area 7 7034 and the second partition 7035 are higher than the second partition 7035 and the first partition 7034. The upper part of the pull rod hook 8 cannot slide backwards. Under the reset action of the reset spring 13, the upper part of the pull rod hook 8 slides from the first partition 7034 to the second partition 7035 and is positioned at the first water distribution gear 7032. At this time, water flows out of the first water outlet channel 101, but the water is blocked by the third water distribution sealing ring 6 and cannot flow into the second water outlet channel 103. Then, the bouncing core 7 is pressed. Since the height of the first partition 7034 and the second partition 7035 is higher than the height of the second partition 7035 and the first partition The upper part of the pull rod hook 8 cannot slide backward because of the height of the adjacent part of the second partition area 7035 7036. The upper part of the pull rod hook 8 slides from the second partition area 7035 to the third partition area 7036, and the bouncing core 7 is released. Since the height of the adjacent part of the second partition area 7035 and the third partition area 7036 is higher than the height of the adjacent part of the third partition area 7036 and the second partition area 7035, the upper part of the pull rod hook 8 cannot slide backward. Under the reset action of the reset spring 13, the upper part of the pull rod hook 8 slides and is positioned at the second water diversion gear 7033. At this time, the water is blocked by the third water diversion sealing ring 6 and cannot flow out from the first water outlet channel 101. The water flows from the first water outlet channel 101 through the passage Water flows into the second water outlet channel 103 through the hole 105, and then flows out from the second water outlet channel 103, pressing the bouncing core 7, and the upper part of the pull rod hook 8 slides from the third partition area 7036 to the fourth partition area 7037, and then the bouncing core 7 is released. Since the height of the third partition area 7036 and the fourth partition area 7037 adjacent to each other is higher than the height of the fourth partition area 7037 and the third partition area 7036 adjacent to each other, the upper part of the pull rod hook 8 cannot slide backwards. Under the reset action of the reset spring 13, the upper part of the pull rod hook 8 slides from the fourth partition area 7037 to the fifth partition area 7038, and is positioned at the closed position 7031, returning to its initial state.When the upper part of the pull rod hook 8 is in the first water-dividing gear position 7032, the bouncing core 7 can be pressed for a long time. Since the height of the first partition area 7034 and the second partition area 7035 adjacent to each other is higher than the height of the second partition area 7035 and the first partition area 7034 adjacent to each other, the upper part of the pull rod hook 8 cannot slide backwards. The upper part of the pull rod hook 8 slides directly from the first water-dividing gear position 7032 to the fourth partition area 7037, and then the bouncing core 7 is released. Since the height of the third partition area 7036 and the fourth partition area 7037 adjacent to each other is higher than the height of the fourth partition area 7037 and the third partition area 7036 adjacent to each other, the upper part of the pull rod hook 8 cannot slide backwards. Under the resetting action of the resetting spring 13, the upper part of the pull rod hook 8 slides from the fourth partition area 7037 to the fifth partition area 7038, and is positioned at the closing gear position 7031.
