[0002] like Figure 1 The diagram shown is an exploded view of an existing inlet valve, which mainly includes a top cover, a top cover fitting, a float assembly, a valve core, a housing, and a base. The top cover fitting is located at the top of the valve core and housing, and it mates with a sealing gasket in the top cover. When the sealing gasket is open, water enters the inlet valve; when the sealing gasket is closed, the inlet valve stops flowing. This inlet valve design involves many parts, resulting in numerous and complex assembly steps. Multiple components require sealing to prevent leakage, further increasing the assembly difficulty and ultimately leading to high production costs.

[0003] In view of this, the inventors of this application have invented a new type of water inlet valve. Utility Model Content

[0037] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0038] It should be noted that in this utility model, the terms "upper", "lower", "left", "right", "vertical", "horizontal", "inner", and "outer" are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element of this utility model must have a specific orientation, and therefore should not be construed as a limitation of this utility model. Example

[0039] Cooperate Figures 2 to 8 As shown, this utility model discloses a novel water inlet valve, which is used for water inlet to a toilet tank. The entire water inlet valve has few parts, is easy to assemble, has a reasonable and compact structure, and has low production costs.

[0040] Cooperate Figures 2 to 8 As shown, a novel water inlet valve includes:

[0041] Upper cover 10, wherein the upper cover 10 is provided with a sealing gasket 11;

[0042] The valve body 20 has an upper cover 10 located on top of it. The valve body 20 is an integrally formed structure. The valve body 20 includes an inlet channel 21 and an outlet channel 22. The inlet channel 21 has an outlet 211 that communicates with the outlet channel 22. The sealing gasket 11 is sealed to the outlet 211.

[0043] The float assembly 30 includes a float 31, the buoyancy of which changes cause the sealing gasket 11 to open or seal the outlet 211;

[0044] The base 40 is connected to the valve body 20. The base 40 includes a water inlet 41, and the water inlet channel 21 is connected to the water inlet 41.

[0045] The bottom of the base 40 is fixedly connected to the water tank, and the top of the base 40 is connected to the valve body 20. The inlet 41 of the base 40 is connected to an external water source, and the external water source enters the inlet through the inlet 41. When the sealing gasket 11 opens the outlet 211, the water flow in the inlet channel 21 enters the outlet channel 22 through the outlet 211, and then enters the water tank, at which time the inlet valve takes in water. When the sealing gasket 11 seals the outlet 211, the water flow in the inlet channel 21 cannot enter the outlet channel 22, and no water enters. The opening or closing of the outlet 211 by the sealing gasket 11 is related to the change in buoyancy of the float 31 of the float assembly 30. The change in buoyancy of the float 31 leads to a change in the pressure of the back pressure chamber of the sealing gasket 11, which in turn causes the sealing gasket 11 to move. The change in buoyancy of the float 31 causes the outlet 211 to open or close in a sealed manner. This part of the structure is a conventional design in this field and will not be described in detail here.

[0046] The valve body 20 adopts an integrated molding structure, which directly cooperates with the upper cover 10 and the base 40, reducing the number of parts of the entire water inlet valve, reducing assembly steps, and reducing leakage points, effectively reducing assembly difficulty and production costs.

[0047] Cooperate Figures 3 to 7 As shown, the valve body 20 is designed as follows: The valve body 20 includes an integrally formed inner tube 212 and an outer tube 221. The outer tube 221 surrounds the outer periphery of the inner tube 212. The hollow channel of the inner tube 212 is the water inlet channel 21, and the gap between the outer tube 221 and the inner tube 212 is the water outlet channel 22. The valve body 20 is an integrally formed structure, with both the outer tube 221 and the inner tube 212 extending longitudinally. The top end mates with the upper cover 10, and the bottom end mates with the base 40.

[0048] The top end of the inner tube 212 is the outlet 211, which is provided with multiple sealing protrusions 213 that cooperate with the sealing gasket 11. The inlet 41 is located on the base 40. Water flows into the base 40 from the inlet and upwards into the inlet channel 21. The top end of the inlet channel 21 (the top end of the inner tube 212) is the outlet 211. When the sealing gasket 11 seals the outlet 211, the sealing gasket 11 and the sealing protrusions 213 are in a sealed fit. When the sealing gasket 11 moves upwards to open the outlet 211, the water in the inlet channel 21 flows out from the gaps between the sealing protrusions 213.

[0049] The outer pipe section 221 has a water passage hole 222 on its side. Water from the inlet channel 21 flows through the outlet 211 and the water passage hole 222 into the outlet channel 22. The inner pipe section 212 and the outer pipe section 221 are integrally connected at the top of the valve body 20. The water passage hole 222, which connects the outlet channel 22 and the inlet channel 21, is located on the side of the outer pipe section 221. Water flowing out from the outlet 211 enters the outlet channel 22 through the water passage hole 222 and flows into the water tank through the outlet channel 22.

[0050] Cooperate Figures 2 to 4 , Figure 8 As shown, the base 40 and valve body 20 are fitted together as follows: the top of the base 40 is sealed and fitted onto the outer periphery of the inner tube 212. A sealing ring is provided between the outer wall of the inner tube 212 and the inner wall of the base 40 to achieve a seal between the base 40 and the inner tube 212, preventing water leakage from the water inlet channel 21.

[0051] The top of the base 40 is detachably fixed to the outer tube 221, and the base 40 and the outer tube 221 can be connected and fixed at different positions to adjust the height of the inlet valve. The detachable connection of the base 40 and the outer tube 221 facilitates convenient assembly of the base 40 and the valve body 20. Furthermore, the base 40 and the outer tube 221 can be connected and fixed at different positions according to actual needs to adjust the overall height of the inlet valve after assembly, allowing the inlet valve to adapt to different height requirements. Additionally, after the float assembly 30 is installed and assembled, connecting and fixing the base 40 and the outer tube 221 at different positions can also adjust the height of the float 31 relative to the bottom of the water tank, thus adjusting the water level in the tank.

[0052] The base 40 and valve body 20 are connected and fixed by the following structure: the outer wall of the base 40 is provided with a buckle 42, and the outer tube 221 is provided with a plurality of longitudinally arranged elastic hooks 223. The buckle 42 can engage and fix with the elastic hooks 223. The buckle 42 and the hooks cooperate to facilitate disassembly and assembly, and the multiple hooks design facilitates adjustment of the water inlet valve height.

[0053] In this embodiment, the outer tube 221 is provided with a clearance through hole 224, the elastic hook is provided along one side of the clearance through hole 224, and the base 40 is marked corresponding to the clearance through hole 224. The design of the clearance through hole 224 allows for easy viewing of the corresponding mark on the base 40 at any time.

[0054] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
