[0023] See also Figures 1 to 4An intelligent actuator control assembly includes an electronic housing 7 and an electronic screen 20. The electronic housing 7 is provided with three button holes, one knob hole, and an electronic screen installation window. A button 2 is installed in each button hole, a knob 11 is installed in the knob hole, and the electronic screen 20 is installed in the electronic screen installation window. The electronic housing 7 is provided with a brim 19 to protect the buttons 2 and knob 11 from rain. A button magnet 3 is installed at the lower end of each button 2, and a button spring 6 is provided between the button magnet 3 and the bottom of the button hole. A first Hall effect element 8 is provided directly below the button hole of the electronic housing to cooperate with the button magnet 3. Each button 2 is threadedly engaged with the button hole via an external thread 407 on the lower side of a locking nut 4. An annular flange 201 is provided at the lower end of each button 2, and a limiting flange 408 extends inward from the upper end of the locking nut 4. The annular flange 201 at the lower end of the button 2 and the limiting flange 408 at the upper end of the locking nut 4 ensure that the button 2 will not disengage from the locking nut 4. The upper side of the locking nut 4 is provided with a first flange 402 and a second flange 404, so that an annular groove 406 is formed between the first flange 402 and the second flange 404, a plurality of first exhaust grooves 401 are provided on the inner side of the first flange 402 of the locking nut 4, a plurality of second exhaust grooves 403 are provided on the outer side of the first flange 402, and a plurality of third exhaust grooves 405 are provided on the upper surface of the second flange 404 of the locking nut 4 to form an exhaust channel. When the button is pressed, the gas in the button hole can discharge the excess gas through the exhaust channel formed by the first, second, third exhaust grooves and the annular groove 406 to ensure the air pressure balance and make the leather cup 1 will not be expanded by compressed gas, avoiding waterproof failure. The pressing end of the button 2 is provided with a mounting ring groove. The small diameter end of a leather cup 1 is inserted into the mounting ring groove, and the large diameter end is clamped by the first flange 402 of the locking nut 4, so that the large diameter end of the leather cup 1 is closely attached to the surface of the second flange 404 of the locking nut 4. The diameter of the first flange 402 of the locking nut 4 is smaller than the diameter of the second flange 404, ensuring that the leather cup 1 can be clamped by the first flange 402 while ensuring that the locking nut 4 forms an exhaust channel. An O-ring 5 is provided between the locking nut 4 and the button hole for sealing, preventing rainwater from entering through the connection between the locking nut 4 and the button hole. A knob magnet 15 is installed at the lower end of the knob 11. Multiple second Hall elements 16 are provided below the knob hole of the electronic cover housing to cooperate with the knob magnet 15. In this embodiment, three second Hall elements 16 are provided below the knob hole of the electronic cover housing to cooperate with the knob magnet 15 , and the three second Hall elements 16 correspond to the three knob function positions on the knob 11 respectively.The bottom of the knob hole is provided with a mounting platform, on which a base 14 is mounted. A sliding block 13 is mounted on the base 14. A knob spring 12 is mounted on the mounting cylinder of the sliding block 13. The knob 11 is mounted on the sliding block 13. A countersunk hole is provided on the top surface of the knob 11. A countersunk screw 10 passes through the countersunk hole of the knob 11, the sliding block 13, and the base 14 in sequence to securely connect the knob 11 with the screw hole on the mounting platform of the knob hole. A waterproof cover 9 is interference-fitted within the countersunk hole, so that the top surface of the waterproof cover 9 is flush with the surface of the countersunk hole, preventing rainwater from entering the countersunk hole. A circumferential flange 18 extends downward from the circumference of the knob 11, and an annular protrusion 17 extends upward from the opening of the knob hole. The diameter of the annular protrusion 17 is smaller than the diameter of the circumferential flange 18 of the knob 11. The annular protrusion 17 cooperates with the circumferential flange 18 to provide waterproof and dustproof properties. The electronic cover housing 7 is further provided with a locking knob 21 for locking the knob 11 so that the knob 11 cannot be rotated.

[0024] When it rains and the button 2 is not pressed, rainwater is first blocked by the brim 19 of the electronic cover 7. The remaining rainwater is blocked by the leather cup 1. Even if rainwater flows into the third venting slot 405 on the second flange 404, it is blocked by the first flange 402 and flows out through the annular groove 406 between the first and second flanges 402, 404, preventing the rainwater from entering the button 2. When it rains and the button 2 is pressed, the button hole is vented through the venting channel on the locking nut, preventing water from entering the button 2. When it rains and the button 2 is released, air is drawn into the button hole, and rainwater flowing into the third venting slot 405 on the second flange 404 is blocked by the first flange 402 and flows out through the annular groove 406 between the first and second flanges 402, 404, preventing the rainwater from entering the button 2. The knob 11 cooperates with the annular protrusion 17 of the knob hole through the circumferential flange 18 to ensure that rainwater cannot enter the interior of the knob.
