Description

Technical Field

[0001] This utility model relates to the field of bathroom product technology, specifically to a float adjustment mechanism for a water inlet valve and a water inlet valve. Background Technology

[0002] With the development of the times, consumers' aesthetic preferences for toilet tanks have shifted towards thinner and narrower designs. This has led to a corresponding decrease in the internal space of the tank, resulting in the following common problems: The smaller internal space means the inlet valve float has a smaller and relatively fixed installation position, making it prone to getting stuck against the tank wall / drain valve, causing it to float up and fail to stop the water flow. Therefore, the inlet valve needs to be installed correctly the first time; otherwise, the float will get stuck, making installation difficult. Furthermore, after the inlet valve is installed, adjusting the float position requires removing the nut, disassembling the float, and reinstalling it, which is inconvenient.

[0003] In view of this, the inventors of this application have invented a float adjustment mechanism for an inlet valve and an inlet valve. Utility Model Content

[0004] The purpose of this utility model is to provide a float adjustment mechanism and inlet valve that can conveniently and quickly adjust the position of the float.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a float adjustment mechanism for an inlet valve, comprising:

[0006] The valve body has a top cover on its top.

[0007] A float assembly includes a float that is movably fitted onto the valve body and is connected to the upper cover;

[0008] A retaining ring is located on the top of the valve body. The upper cover is rotatably connected to the retaining ring. The upper cover rotates relative to the retaining ring, thereby causing the float to rotate relative to the valve body.

[0009] Furthermore, the valve body or retaining ring is provided with a limiting part, and the upper cover is provided with a mating part that cooperates with the limiting part, and the mating part rotates within the range defined by the limiting part.

[0010] Furthermore, the limiting part is a rib provided on the side of the valve body or retaining ring, and the mating part is an extension provided on the side of the upper cover.

[0011] Furthermore, the angle of rotation of the upper cover relative to the retaining ring is 0-180 degrees.

[0012] Furthermore, it includes a positioning structure, which includes a plurality of positioning teeth arranged along the rotation direction of the upper cover and a positioning block that engages with the positioning teeth. One of the positioning teeth and the positioning block is located on the upper cover, and the other is located on the retaining ring or valve body.

[0013] Furthermore, the upper cover is provided with a rotating groove, and the retaining ring is provided with a hook that can be rotatably engaged with the rotating groove.

[0014] Furthermore, the float assembly also includes a lifting rod and an adjusting screw. The float is threadedly connected to the adjusting screw. One end of the lifting rod is connected to the upper cover, and the other end is connected to the adjusting screw. Rotation of the upper cover causes the float assembly to rotate accordingly.

[0015] Furthermore, the retaining ring and the valve body are either detachably connected or integrally formed.

[0016] Furthermore, the retaining ring and the valve body are detachably connected. The outer peripheral side of the valve body is provided with multiple limiting protrusions, and a clearance groove is formed between adjacent limiting protrusions. The valve body is also provided with a fixing rib. The inner wall of the retaining ring is provided with a locking protrusion corresponding to the clearance groove, and the retaining ring is provided with a locking rib corresponding to the fixing rib. The locking protrusion is engaged through the clearance groove. Then the retaining ring rotates until the locking protrusion and the limiting protrusion are engaged, realizing the forward rotation limitation of the retaining ring. At this time, the locking rib passes over the limiting rib, realizing the reverse rotation limitation of the retaining ring.

[0017] An inlet valve includes the aforementioned float adjustment mechanism.

[0018] By adopting the above technical solution, this utility model has the following advantages compared with the prior art:

[0019] This utility model relates to a float adjustment mechanism and an inlet valve. By setting a float adjustment mechanism, the relative position of the float and the valve body can be quickly adjusted by simply rotating the top cover. This makes the installation of the inlet valve simpler, and the position of the float can also be adjusted after the inlet valve is installed, making operation convenient.

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.

[0037] 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

[0038] Cooperate Figures 1 to 8 As shown, this utility model discloses an adjustment mechanism for the float 31 of a water inlet valve, which is used to adjust the position of the float 31. Thus, the position of the float 31 does not need to be considered too much when installing the water inlet valve, making installation convenient. After the water inlet valve is installed, the position of the float 31 can also be adjusted at any time.

[0039] Cooperate Figures 1 to 8As shown, a float 31 adjustment mechanism for an inlet valve includes:

[0040] Valve body 10, the top of which is provided with a top cover 20;

[0041] The float assembly 30 includes a float 31, which is movably sleeved on the valve body 10 and connected to the upper cover 20.

[0042] A retaining ring 40 is located on the top of the valve body 10. The upper cover 20 is rotatably connected to the retaining ring 40. The upper cover 20 rotates relative to the retaining ring 40, thereby causing the float 31 to rotate relative to the valve body 10.

[0043] The retaining ring 40 is fixedly connected to the valve body 10 and is fixed to the top of the valve body 10. The upper cover 20 is rotatably connected to the retaining ring 40. The float 31 is connected to the upper cover 20 and the float 31 is linked with the upper cover 20. The upper cover 20 rotates relative to the retaining ring 40, that is, the upper cover 20 rotates relative to the valve body 10, which in turn drives the float 31 to rotate relative to the valve body 10, rotating the float 31 to different positions so that it will not be stuck, avoiding obstruction of the float 31's ascent or descent, and ensuring that its function can be realized.

[0044] The float assembly 30 further includes a lifting rod 32 and an adjusting screw 33. The float 31 is threadedly connected to the adjusting screw 33. One end of the lifting rod 32 is connected to the upper cover 20, and the other end is connected to the adjusting screw 33. Rotation of the upper cover 20 causes the float assembly 30 to rotate accordingly. Parts of the float assembly 30 are prior art and will not be described in detail here. The float 31 is connected to the upper cover 20 via the adjusting screw 33 and the lifting rod 32, causing the float 31 and the upper cover 20 to rotate in tandem. The upper cover 20 rotates relative to the retaining ring 40 and the valve body 10, causing the entire float assembly 30 (float 31, lifting rod 32, adjusting screw 33) to rotate accordingly.

[0045] Cooperate Figures 1 to 2 , Figures 7 to 8 As shown, the upper cover 20 can only rotate within a certain range relative to the retaining ring 40. This rotation angle can be set according to actual needs. In this embodiment, the rotation angle of the upper cover 20 relative to the retaining ring 40 is 0-180 degrees. A rotation range of 180 degrees is sufficient to meet the usage requirements.

[0046] The rotation of the upper cover 20 is restricted by the following structure: the valve body 10 or the retaining ring 40 is provided with a limiting part 11, and the upper cover 20 is provided with a mating part 21 that cooperates with the limiting part 11. The mating part 21 rotates within the range defined by the limiting part 11. Specifically, the limiting part 11 is a protruding rib provided on the side of the valve body 10 or the retaining ring 40, and the mating part 21 is an extension protruding outward from the side of the upper cover 20. In this embodiment, there are two limiting parts 11, symmetrically provided on the side of the valve body 10.

[0047] Cooperate Figures 1 to 2 , Figures 5 to 7 As shown, the float 31 adjustment mechanism also includes a positioning structure for fixing the position of the upper cover 20. When the upper cover 20 is rotated to the desired position, the positioning structure fixes the upper cover 20. The positioning structure includes multiple positioning teeth 22 arranged along the rotation direction of the upper cover 20 and positioning blocks 41 that engage with the positioning teeth 22. One of the positioning teeth 22 and the positioning block 41 is located on the upper cover 20, and the other is located on the retaining ring 40 or the valve body 10. The engagement of the positioning block 41 with the positioning teeth 22 fixes the upper cover 20. Rotating the upper cover 20 allows the positioning block 41 to engage with different positioning teeth 22, thus adjusting the position of the upper cover 20. In this embodiment, the positioning teeth 22 are located on the outer wall of the upper cover 20, between the two limiting parts 11. One side engages with the mating part 21, and the other side is provided with the positioning teeth 22. The positioning block 41 is located on the retaining ring 40. Alternatively, the positioning block 41 can be located on the upper cover 20, and the positioning teeth 22 can be located on the retaining ring 40.

[0048] Cooperate Figures 4 to 7 As shown, the upper cover 20 and the retaining ring 40 are coupled as follows: the upper cover 20 is provided with a rotating groove 23, and the retaining ring 40 is provided with a hook 42 that can be rotatably engaged with the rotating groove 23. The upper cover 20 and the retaining ring 40 are detachably connected. The upper cover 20 and the retaining ring 40 are engaged by the hook 42 of the retaining ring 40 engaging with the rotating groove 23 of the upper cover 20. The hook 42 can rotate within the rotating groove 23, allowing the upper cover 20 to rotate relative to the retaining ring 40. Preferably, the rotating groove 23 is an annular groove arranged circumferentially along the inner wall of the upper cover 20, and multiple hooks 42 are provided to ensure a stable installation and connection between the two.

[0049] Cooperate Figures 4 to 6 , Figure 8 As shown, the retaining ring 40 is either detachably connected to the valve body 10 or integrally formed. That is, the retaining ring 40 can be detachably connected to the valve body 10, requiring a connection structure between the retaining ring 40 and the valve body 10 and the upper cover 20; alternatively, the retaining ring 40 can be integrally formed with the valve body 10, eliminating the need for a separate connection structure. In this embodiment, the retaining ring 40 is detachably connected to the valve body 10, and the connection structure between the retaining ring 40 and the valve body 10 is as follows:

[0050] The valve body 10 has multiple limiting protrusions 12 on its outer peripheral side, and a relief groove 13 is formed between adjacent limiting protrusions 12. The valve body 10 also has a fixing rib 14. The inner wall of the retaining ring 40 has a locking protrusion 43 corresponding to the relief groove 13, and the retaining ring 40 has a locking rib 44 corresponding to the fixing rib 14. The locking protrusion 43 is engaged through the relief groove 13. Then the retaining ring 40 rotates until the locking protrusion 43 and the limiting protrusion 12 are engaged, so as to realize the forward rotation limitation of the retaining ring 40. At this time, the locking rib 44 passes over the limiting protrusion, so as to realize the reverse rotation limitation of the retaining ring 40.

[0051] Specifically, the valve body 10 has a mounting surface 15 at its top for mounting a retaining ring 40. The retaining ring 40 is fitted around the outer periphery of the valve body 10, and its bottom surface mates with the mounting surface 15. The outer wall of the valve body 10 has multiple limiting protrusions 12, with a certain distance between adjacent limiting protrusions 12 forming the clearance groove 13. Limiting ribs are located on the mounting surface 15 and protrude from it. Engaging ribs 44 are located on the bottom surface of the retaining ring 40 and protrude from it. Engaging ribs 43 are located on the inner wall of the retaining ring 40 and are aligned with the clearance groove 13. With a corresponding configuration, the engaging protrusion 43 can be inserted downwards into the relief groove 13, allowing the retaining ring 40 to be fitted onto the outer periphery of the top of the valve body 10, with its bottom surface engaging with the mounting plane 15. Then, rotating the retaining ring 40 clockwise causes it to rotate relative to the valve body 10 until the engaging protrusion 43 engages with the limiting protrusion 12, preventing further clockwise rotation. At this point, the engaging rib 44 has rotated past the limiting rib, achieving a limiting engagement with the limiting rib and restricting the retaining ring 40 from rotating in the opposite direction. This secures the retaining ring 40 to the valve body 10. To remove the retaining ring 40, considerable force is required to rotate it in the opposite direction, causing the engaging protrusion 44 to pass past the limiting rib. Continue rotating in the opposite direction until the engaging protrusion aligns with the relief groove 13. The retaining ring 40 can then be pulled upwards and removed from the valve body 10. At least one of the limiting protrusion 12 or the engaging protrusion 43 is L-shaped, providing a limiting engagement.

[0052] Cooperate Figures 1 to 8 As shown, this utility model also discloses a water inlet valve, including the above-mentioned float 31 adjustment mechanism. Through the float 31 adjustment mechanism, the relative position of the float 31 and the valve body 10 can be adjusted, making the installation of the water inlet valve simpler. After the water inlet valve is installed, the position of the float 31 can be adjusted by simply rotating the upper cover 20, making the operation convenient.

[0053] 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.
