Abstract
Description
Technical Field
[0001] This utility model relates to the field of electric actuator technology, and specifically to an electric actuator with a moisture-proof structure. Background Art
[0002] The broadest definition of an actuator is: a drive device that provides linear or rotary motion, utilizing some kind of driving energy and operating under the action of some control signal. Actuators use liquid, gas, electricity, or other energy sources and convert them into driving action through motors, cylinders, or other devices. Their basic types include three drive methods: part-turn, multi-turn, and linear.
[0003] The current publication number CN219164910U discloses an electric actuator with a moisture-proof structure, including a protective shell. An electric actuator body is fixedly connected inside the protective shell. A side plate is connected to one side of the protective shell via a mounting structure. Connecting structures are fixedly connected to the top and bottom of the protective shell on one side of the electric actuator body. This electric actuator with a moisture-proof structure allows for the disassembly and replacement of the moisture-proof plate through the cooperation of the mounting box, return spring, and sliding plate. Simultaneously, the moisture-proof plate stably absorbs moisture. The spring force of the return spring consistently pushes the sliding plate out, ensuring better contact between the sliding plate and the top of the moisture-proof plate. The cooperation of the slide rail and slider allows for smoother movement of the sliding plate inside the mounting box. The shape of the mounting box better accommodates moisture-proof plates of different sizes, thus achieving the absorption of moisture of varying weights.
[0004] To address the moisture problem, existing technologies employ a combination of a mounting box, a return spring, and a sliding plate to allow for the removal and replacement of the moisture-proof plate. While the moisture-proof plate can reliably absorb moisture, this approach still results in the electric actuator generating heat that cannot be quickly dissipated, leading to damage and reduced lifespan over time.

[0031] The present invention will be further described in detail below with reference to embodiments: Example
[0032] like Figure 1-5 As shown, this utility model provides an electric actuator with a moisture-proof structure, including an electric actuator 1, a protective unit 2 on the outside of the electric actuator 1, a removable component 3 on one side of the protective unit 2, and a dustproof and dehumidifying unit 4 inside the protective unit 2. The protective unit 2 includes a protective box 21 and a heat dissipation component 22. The protective box 21 is located outside the electric actuator 1, and the heat dissipation component 22 is located inside the protective box 21. The heat dissipation component 22 includes an air inlet 221, which is located on the top surface of the protective box 21. A positioning groove 222 is provided on one side of the air inlet 221. A fixing bracket 223 is fixedly connected to the inner side of the air inlet 221. A motor 224 is fixedly connected to one side of the fixing bracket 223. A fan blade 225 is fixedly sleeved at the output end of the motor 224. During the daily use of the electric actuator 1, humid air is discharged into the interior of the moisture-absorbing plate 25 through the ventilation hole 24. The moisture-absorbing plate 25 dries the humid air. At the same time, the heat generated during the use of the electric actuator 1 drives the fan blade 225 to work by controlling the motor 224. The fan blade 225 transports the outside air to the interior of the protective box 21 after it is processed by the moisture-absorbing net 42 and the dustproof net 43. Example
[0033] like Figure 1-5As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, a sealing gasket 23 is provided inside the protective box 21, and a plurality of ventilation holes 24 are evenly opened on the bottom surface of the protective box 21. A moisture-absorbing plate 25 is slidably connected to the bottom surface inside the protective box 21. The detachable component 3 includes a limiting groove 31, which is fixedly connected to one side of the protective box 21. A T-shaped rod 32 is provided through the top surface of the limiting groove 31, and a spring 33 is sleeved on the outside of the T-shaped rod 32. One end of the spring 33 is fixedly connected to the limiting groove 31. On the top surface, one end of spring 33 is fixedly connected to one side of positioning block 34. Positioning block 34 is provided on the inner side of spring 33. Positioning hole 35 is opened on the inner side of positioning block 34. The inner side of positioning hole 35 is slidably connected to one end of T-shaped rod 32. By placing electric actuator 1 inside protective box 21, T-shaped rod 32 is pulled to compress spring 33, thereby moving protective box 21 to the other side of electric actuator 1. The sealing gaskets 23 are mutually attached, thereby improving the sealing degree of the connection between protective boxes 21. Example
[0034] like Figure 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the dustproof and dehumidifying unit 4 includes a mounting frame 41, which is disposed inside the air inlet 221. A moisture-absorbing net 42 is snapped onto the inner side of the mounting frame 41, and a dustproof net 43 is snapped onto the inner side of the mounting frame 41. A T-shaped rod 44 is provided through the inner side of the mounting frame 41. The inner side of the T-shaped rod 44 is slidably connected to the inside of the protective box 21. A spring 45 is sleeved on the outer side of the T-shaped rod 44. One end of the spring 45 is fixedly connected to one side of the protective box 21, and the other end of the spring 45 is fixedly connected to one side of the T-shaped rod 44. After long-term use, the T-shaped rod 44 can be pulled out from inside the mounting frame 41, and the mounting frame 41 can be removed. The moisture-absorbing net 42 and the dustproof net 43 can then be replaced.
[0035] The working principle of this moisture-proof electric actuator will be explained in detail below.
[0036] like Figure 1-5As shown, by placing the electric actuator 1 inside the protective housing 21, the T-shaped rod 32 is pulled, causing the spring 33 to compress, thereby moving the protective housing 21 to the other side of the electric actuator 1. The sealing gaskets 23 then adhere to each other, increasing the sealing tightness of the connection between the protective housings 21. The T-shaped rod 32 is then placed inside the positioning block 34, and the elasticity of the spring 33 completes the positioning and installation between the limiting groove 31 and the positioning hole 35. During daily use of the electric actuator 1, humid air is exhausted to the moisture-absorbing plate 25 through the ventilation hole 24. Inside the enclosure, the moisture-absorbing plate 25 dries the humid air. Meanwhile, the heat generated during the operation of the electric actuator 1 drives the fan blade 225 through the control motor 224. The fan blade 225 draws the outside air through the moisture-absorbing net 42 and the dustproof net 43 and delivers it into the interior of the protective box 21. This quickly exhausts the heat generated by the electric actuator 1 from the interior of the protective box 21. After prolonged use, the T-shaped rod 44 can be pulled out from inside the mounting bracket 41, and the mounting bracket 41 can be removed. The moisture-absorbing net 42 and the dustproof net 43 can then be replaced.
[0037] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
