They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0032] Reference Figures 1 to 5As shown, this utility model provides an automatic water control valve, including a front cover 1 and a bottom cover 2 that are fastened together, a float 3 disposed inside between the front cover 1 and the bottom cover 2, a hook 4 connected to the float 3, and a movable rod 5 connected to the hook 4; the front cover 1 has a water inlet hole 6, and the bottom cover 2 has several drain holes 7; the first end of the hook 4 is detachably fixed to the float 3, the middle part of the hook 4 is rotatably connected to the inside of the front cover 1, and the second end of the hook 4 is movably fastened to the first end of the movable rod 5; furthermore, the first end of the hook 4 is detachably fixed to the float 3 by screws. When the float 3 rises, the hook 4 can push the second end of the movable rod 5 to block the water inlet hole 6; when the float 3 falls, the hook 4 can pull the second end of the movable rod 5 away from the water inlet hole 6.

[0033] The water inlet 6 has an L-shaped cross-section, with its vertical L-shaped end extending to the outside of the cover 1 and its horizontal L-shaped end located inside the cover 1. The movable rod 5 remains horizontal at all times, and the horizontal L-shaped end of the water inlet 6 is also horizontal. By setting the water inlet 6 in an L-shape, both the movable rod 5 and the horizontal L-shaped end of the water inlet 6 remain horizontal, ensuring that the movable rod 5 and the horizontal L-shaped end of the water inlet 6 are pressed axially without any tangential force, thus avoiding the formation of an angle and reducing the probability of failure of the closed water control mechanism.

[0034] A silicone plug 8 is detachably connected to the second end of the movable rod 5. Furthermore, an inner hole is formed along the axial direction of the movable rod 5 at the second end of the movable rod 5, through which the silicone plug 8 is connected to the movable rod 5. Several vent holes 9 are formed on one side of the cover 1. By providing vent holes 9, instability in water ingress and failure due to vacuum conditions can be prevented.

[0035] The first end of the movable rod 5 is provided with a through-hole; the hook 4 has an L-shaped cross-section, with its horizontal L-shaped end detachably fixed to the float 3 and its vertical L-shaped end movably passing through the through-hole.

[0036] The middle part of the hook 4 is connected to the inside of the cover 1 via the pivot 10; the hook 4 can rotate relative to the pivot 10. The pivot 10 is implemented by a pin, with a through hole in the middle of the hook 4, the middle part of the pin passing through the through hole and connecting to the hook 4, and the two ends of the pin being fixed to the inside of the cover 1. The hook 4 can rotate around the pin, thereby installing the hook 4 inside the cover 1.

[0037] The cover 1 has at least one guide hole inside; the movable rod 5 passes through the guide hole and can move horizontally relative to the guide hole.

[0038] The top of the bottom cover 2 is provided with a plurality of buckles 12 spaced circumferentially, and the bottom of the top cover 1 has a corresponding locking hole 13 for each buckle 12. The top cover 1 and the bottom cover 2 are fastened together and can be quickly opened by pressing, making them easy to install and remove. Furthermore, the buckle 12 includes a connecting rod extending upward from the top of the bottom cover 2, and a hook at the end of the connecting rod. The top surface of the hook is provided with a guide slope, so that when the top cover 1 is fastened from top to bottom, the hook can quickly slide into the locking hole 13 via the guide slope of the top surface of the hook.

[0039] When using the automatic water control valve, place it at the bottom of a water-holding container, such as watering tray 14. Please refer to [further instructions]. Figure 5 Liquid enters the control valve through inlet 6. Inlet 6 contains a resistance regulating valve 11, which blocks the liquid pressure, reducing pressure surges and preventing valve malfunction. As liquid slowly enters the automatic control valve through inlet 6, it flows through drain 7 into the watering tray 14 containing the valve, ensuring the water level in the valve matches the water level in the tray 14. As the water level rises, please continue referring to... Figure 3 Float 3 gradually rises (rises) due to buoyancy, causing hook 4 to rotate around shaft 10, which in turn pushes moving rod 5 horizontally to the right. When the liquid volume reaches a certain level, float 3 reaches a horizontal state, and silicone plug 8 presses against the inner end face (L-shaped horizontal end) of water inlet 6, preventing liquid from entering and stopping water intake. As the plant absorbs and evaporates water, the water in watering tray 14 gradually decreases. Please continue to refer to... Figure 4 As the water level in the control valve drops, the float 3 also drops, which pulls the movable rod 5 to move horizontally to the left. The silicone plug 8 disengages from the inner end face of the water inlet hole 6, and the liquid can re-enter the automatic control valve. This process is repeated to achieve the effect of automatic water control.
