In order to accurately control the opening angle of the ball valve, the magnet is generally connected to one end of the output shaft of the reducer and the other end is connected to the ball valve. When the reducer drives the output shaft to rotate, the output shaft drives the magnet to rotate synchronously. The electromechanical feedback device reads the rotation angle of the magnet to obtain the rotation angle of the output shaft, and then obtains the opening angle of the ball valve.

[0003] In existing technologies, magnets are generally ring-shaped hollow structures, which are fitted onto the output shaft and glued together to achieve the connection between the magnet and the output shaft. This structure makes magnet installation inconvenient, and the glue makes disassembly difficult during maintenance, resulting in inconvenient repairs. Utility Model Content

Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar parts or parts having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0036] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection or a detachable connection; a mechanical connection or an electrical connection; a direct connection or an indirect connection through an intermediate medium; or the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0038] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0039] like Figures 1-5 As shown, this utility model embodiment provides an actuator, which includes a housing 1, a reducer 2, an adapter 3, a magnet 4, and an electromechanical feedback device.

[0040] The reducer 2 is housed within the housing 1 and includes a motor 21, a gear transmission group 22, and an output shaft 23. The motor 21 drives the output shaft 23 to rotate via the gear transmission group 22. An adapter 3 is located at one end of the output shaft 23, and the adapter 3 has a receiving groove 31 on its upper side away from the output shaft 23. A magnet 4 is housed within the receiving groove 31, and the magnet 4 and the receiving groove 31 are configured for an interference fit, so that when the output shaft 23 rotates, it can drive the magnet 4 to rotate simultaneously via the adapter 3. An electromechanical feedback device (optionally a magnetic encoder) is housed within the housing 1. The Hall element in the electromechanical feedback device can detect the rotation of the magnet 4 to read the rotation angle of the magnet 4, thereby obtaining the rotation angle of the output shaft 23, so as to achieve precise control of the output shaft 23.

[0041] This actuator mounts the adapter 3 onto the output shaft 23, and then installs the magnet 4 into the receiving groove 31 of the adapter 3. The magnet 4 and the receiving groove 31 are interference-fitted to ensure that the magnet 4 is securely installed and to prevent the magnet 4 from coming out of the receiving groove 31. The magnet 4 of this actuator is easy to install, requiring no glue, and is convenient for subsequent disassembly and maintenance.

[0042] In the existing technology, since the magnet 4 needs to be fitted onto the output shaft 23, the magnet 4 must be designed as a hollow annular structure. The hollow annular structure of the magnet 4 has the disadvantage of insufficient magnetic flux, which leads to the electromechanical feedback device being unable to accurately read the rotation angle of the magnet 4. To solve the above problem, after setting the adapter 3, the magnet 4 can be selected as a solid structure. The solid structure of the magnet 4 does not have the problem of insufficient magnetic flux, making the rotation angle detection accurate.

[0043] Optionally, such as Figures 3-4 As shown, the adapter 3 is snapped onto one end of the output shaft 23. That is, the adapter 3 has multiple circumferentially distributed claws 32 on the lower side facing the output shaft 23. The multiple claws 32 surround to form an installation area. The ends of the claws 32 are provided with inwardly extending hooks 321. The outer circumferential surface of the output shaft 23 is provided with an annular groove 231. When the adapter is connected to one end of the output shaft 23, one end of the output shaft 23 can be inserted into the installation area. The hooks 321 extend into the annular groove 231 to ensure that the adapter 3 is installed firmly.

[0044] Furthermore, in order to ensure the accurate initial position of the adapter 3 and to prevent relative rotation between the adapter 3 and the output shaft 23, a limiting part 33 is provided on the lower side of the adapter 3. The limiting part 33 and multiple claws 32 are arranged circumferentially to form an installation area. A limiting plane 232 is provided on the outer circumferential surface of the output shaft 23, located on the annular groove 231. When the output shaft 23 is inserted into the installation area, the limiting part 33 abuts against the limiting plane 232. When the adapter 3 is installed, the limiting part 33 faces and abuts against the limiting plane 232, so that the initial position of the adapter 3 is accurate. The limiting plane 232 can effectively limit the rotation of the adapter 3 relative to the output shaft 23 by abutting against the limiting part 33.

[0045] Optionally, the limiting part 33 includes a limiting plate 331 and a limiting rib 332 disposed on the limiting plate 331 facing the installation area. Two limiting ribs 332 can be provided, and the two limiting ribs 332 are distributed at intervals and both abut against the limiting plane 232. This structure is simple in design and has low design cost.

[0046] To ensure that the limiting part 33 has a strong load-bearing capacity, the limiting part 33 also includes a reinforcing rib 333 disposed on the side of the limiting plate 331 away from the installation area. Two reinforcing ribs 333 can be provided, and the two reinforcing ribs 333 are distributed at intervals and are both connected to the lower side of the adapter 3. When the limiting rib 332 abuts against the limiting plane 232, the reinforcing rib 333 can provide a strong supporting force to prevent the limiting rib 332 from sliding off the limiting plane 232.

[0047] In this embodiment, three claws 32 are provided, and the limiting part 33 and the three claws 32 are evenly distributed circumferentially.

[0048] Optionally, the lower side of the adapter 3 is provided with a plurality of circumferentially distributed notches 34 corresponding one-to-one with a plurality of claws 32 in the installation area, and the claws 32 are located at the edges of the corresponding notches 34. This notch 34 structure makes it easier for the claws 32 to deform during the process of engaging with the annular groove 231.

[0049] To facilitate the assembly and disassembly of magnet 4, such as Figure 5As shown, the groove wall inside the receiving groove 31 is provided with a plurality of circumferentially distributed protrusions 311. When the magnet 4 is installed in the receiving groove 31, the outer peripheral surface of the magnet 4 abuts against the plurality of protrusions 311 to achieve an interference fit between the magnet 4 and the receiving groove 31.

[0050] Optionally, the protrusion 311 may be selected as a protrusion or strip block provided on the groove wall of the receiving groove 31.

[0051] When the protrusion 311 is set as a strip block, the end of the protrusion 311 facing away from the bottom of the receiving groove 31 is provided with an inclined chamfer to facilitate the magnet 4 to be embedded in the receiving groove 31.

[0052] To allow users to directly observe the rotation angle of the output shaft 23, such as Figure 5 Combined Figure 1 As shown, an indicator arrow 35 is provided on the upper side of the adapter 3, and an observation window 11 is provided at the corresponding position of the housing 1 and the adapter 3. When the output shaft 23 rotates and drives the adapter 3 to rotate, the indicator arrow 35 points in different directions. The indicator arrow 35 can be observed through the observation window 11 to assist in observing the rotation angle of the output shaft 23. It can be understood that the observation window 11 is provided with a transparent plate, through which the adapter 3 can be observed.

[0053] This utility model embodiment also provides a water outlet pile, which includes a ball valve and the aforementioned actuator. One end of the output shaft 23, away from the adapter 3, is connected to the valve stem of the ball valve. That is, when the output shaft 23 rotates, it can simultaneously drive the valve stem of the ball valve to rotate, thereby controlling the opening and closing angle of the ball valve. The user reads the rotation angle of the magnet 4 through the electromechanical feedback device, and then obtains the rotation angle of the output shaft 23. The rotation angle of the output shaft 23 can reflect the size of the opening and closing angle of the ball valve, thereby achieving precise control of the water flow.

[0054] By installing the aforementioned actuator, the water outlet pile achieves precise control over the opening and closing angle of the ball valve, thereby enabling precise control over the water flow.
