Description

Technical Field

[0001] This application relates to the field of wall switch technology, and more particularly to a wall switch with a protective structure. Background Technology

[0002] Wall switches with protective covers are a type of switch designed to enhance safety, typically preventing accidental electric shock or misoperation. A common design feature is the protective cover to prevent children or unauthorized personnel from accessing the internal structure, thus avoiding the risk of electric shock. Wall switches with protective covers prioritize safety and reliability and are widely used in various locations requiring high safety. When selecting and using them, appropriate products should be chosen based on specific needs and environmental conditions, and installation and maintenance requirements should be strictly followed.

[0003] Currently, a Chinese utility model patent application with a publication date of July 30, 2024, and publication number CN 221447044U, discloses a power switch with a protective structure, including a base plate and a fixing block. The fixing block is fixedly connected to the top of the base plate, and a positioning hole is formed through the outer wall of the fixing block. A shell is movably connected to the outer wall of the base plate. A fixing groove matching the fixing block is formed on the side of the fixing plate near the wall. The inner wall of the fixing groove is respectively formed with a first sliding groove and a second sliding groove corresponding to the positioning hole. A rotating shaft is fixedly connected to one side of the limiting block, and a flip cover is rotatably connected to the end of the rotating shaft away from the limiting block. In this utility model, the operation is more convenient when replacing a damaged or aged shell through the cooperation of the limiting components. At the same time, the cooperation of the torsion spring and the flip cover prevents the operator from forgetting to close the flip cover, reducing the entry of external dust or moisture and other debris into the wall switch, thus protecting the power switch.

[0004] In related technologies, wall switches with protective structures use protective covers to protect the switch. However, these covers may hinder heat dissipation from the switch's interior, leading to heat buildup. If the switch operates under high load for extended periods, it may overheat, potentially damaging internal components or even causing a fire.

[0005] Therefore, it is necessary to provide a wall switch with a protective structure to solve the above problems. Utility Model Content

[0006] This application provides a wall switch with a protective structure to improve the technical problem in related technologies where a protective cover is used to protect the switch, but the cover may hinder the dissipation of heat inside the switch, leading to heat accumulation.

[0022] Based on this, in order to improve the technical problem in the related technology that the protective cover used to protect the switch may hinder the heat dissipation inside the switch and cause heat accumulation, the embodiments of this application provide the following solution.

[0023] Please refer to the following: Figures 1 to 4 This application provides a wall switch with a protective structure. The wall switch with a protective structure includes a switch body 1, a protective cover 2, a heat dissipation component 3, a snap-fit ​​component 5, and a rotating component 6. The protective cover 2 is disposed on the switch body 1, the snap-fit ​​component 5 is disposed on the switch body 1, the rotating component 6 is disposed on the switch body 1, and the heat dissipation component 3 is disposed on the protective cover 2.

[0024] In some embodiments, please refer to the following: Figures 1 to 3The heat dissipation assembly 3 includes a heat dissipation box 32, a fan motor 31, and a cooling fan 33. The protective cover 2 has a connection hole. The heat dissipation box 32 is mounted on the protective cover 2 through the connection hole. The fan motor 31 is mounted on the heat dissipation box 32. The cooling fan 33 is mounted on the fan motor 31. The cooling fan 33 is coaxially driven with the output shaft of the fan motor 31. The heat dissipation box 32 has a heat dissipation hole 34 at one end near the connection hole and a heat absorption hole 35 at the other end away from the connection hole. The protective cover 2 has a square hole through which several metal heat dissipation strips 4 are installed.

[0025] With this configuration, after the switch body 1 has been operating for a long time, it generates a significant amount of heat, which may lead to heat accumulation. Simultaneously, the fan motor 31 starts, driving the cooling fan 33 to rotate. External air enters the heat sink 32 through the heat dissipation holes 34, and hot air is exhausted through the heat absorption holes 35. Meanwhile, the metal heat sink 4 on the protective cover 2 provides auxiliary cooling. This combination of multiple cooling methods—fan cooling, heat dissipation holes 34, and auxiliary cooling with the metal heat sink 4—creates an effective air convection circulation, improving the overall cooling effect. The fan motor 31 drives the fan to provide active cooling, and the heat dissipation holes 34 and heat absorption holes 35 form an effective airflow channel. Thus, by combining fan cooling, heat dissipation holes 34, and auxiliary cooling with the metal heat sink 4, the system can more comprehensively address the heat generated by the switch body 1 during prolonged operation. The fan motor 31, after starting, drives the cooling fan 33 to rotate, forming an active cooling mechanism to ensure that heat is removed promptly. The design of the heat dissipation holes 34 and heat absorption holes 35 provides an effective channel for air convection, allowing cool external air to enter the heat sink 32 and hot air to be smoothly exhausted. This combined active and passive cooling mechanism significantly improves heat dissipation efficiency. The auxiliary cooling effect of the metal heat sink 4 is also crucial. The metal material has excellent thermal conductivity, enabling it to quickly absorb and disperse heat, further enhancing the cooling effect. This design also offers excellent stability and reliability. By creating an effective air convection circulation, the system can continuously and stably dissipate heat, keeping the equipment operating within a suitable temperature range. This not only improves the equipment's operating efficiency but also reduces maintenance needs due to overheating, lowering long-term operating costs.

[0026] In some embodiments, please refer to the following: Figures 1 to 4The rotating assembly 6 includes a fixing block 61, a rotating shaft 62, and a connecting block 63. The fixing block 61 is mounted on the switch body 1 and has a circular hole. The rotating shaft 62 is mounted on the fixing block 61 through the circular hole. The connecting block 63 is mounted on the protective cover 2 and is rotatably connected to the rotating shaft 62. The snap-fit ​​assembly 5 includes a snap-fit ​​support column 51, a connecting strip 55, an annular protective pad 52, a fixing rod 53, and a transmission ball 54. The snap-fit ​​support column 51 is mounted on the protective cover 2, the annular protective pad 52 is fitted onto the snap-fit ​​support column 51, the connecting strip 55 is mounted on the end of the snap-fit ​​support column 51 away from the protective cover 2, the fixing rod 53 is mounted on the switch body 1, and the transmission ball 54 is mounted on the end of the fixing rod 53 away from the switch body 1. The protective cover 2 has a notch 7, a rubber pad 11 is mounted on the switch body 1, and an auxiliary handle 8 is mounted on the protective cover 2.

[0027] With this design, when opening the protective cover 2, the user opens it using the auxiliary handle 8. First, the transmission ball 54 on the fixing rod 53 is removed from the annular protective pad 52 on the locking support 51. By rotating the protective cover 2, the user can easily insert the plug into the switch body 1. The connecting wire on the plug can pass through the notch 7, reducing the possibility of the connecting wire restricting the closing of the protective cover 2. When closing the protective cover 2, rotating it causes the connecting block 63 to rotate on the rotating shaft 62. The protective cover 2 first contacts the rubber pad 11 on the bracket, buffering the pressure. Simultaneously, by passing the transmission ball 54 on the fixing rod 53 through the annular protective pad 52 on the locking support 51, the annular protective pad 52 abuts against the transmission ball 54, restricting the opening of the protective cover 2. Thus, during the opening process, the user can easily open the protective cover 2 using the auxiliary handle 8. This design simplifies the operation steps, making it more convenient for the user to open the protective cover 2. In particular, by removing the transmission ball 54 on the fixing rod 53 from the annular protective pad 52 on the locking support 51, the user can smoothly begin to rotate the protective cover 2. This structure not only ensures the stability of the protective cover 2 but also provides a flexible opening method. When closing the protective cover 2, it first contacts the rubber pad 11 on the bracket. This design acts as a buffer, reducing the impact and noise during closing and extending the service life of the equipment. Simultaneously, by passing the transmission ball 54 on the fixing rod 53 through the annular protective pad 52 on the locking support 51, the annular protective pad 52 abuts against the transmission ball 54, restricting the opening of the protective cover 2. This design provides a reliable locking mechanism, ensuring that the protective cover 2 will not open accidentally when closed, increasing safety. This design also offers excellent practicality and durability. The combination of the buffering effect of the rubber pad 11 and the locking mechanism of the annular protective pad 52 makes the entire process smoother and more reliable. The cooperative design of the transmission ball 54 and the annular protective pad 52 not only improves the product's service life but also reduces maintenance requirements.

[0028] The implementation principle of a wall switch with a protective structure according to this application embodiment is as follows: After the switch body 1 has been working for a long time, most of the heat generated by the switch body 1 may accumulate. At the same time, the fan motor 31 starts, and the operation of the fan motor 31 drives the cooling fan 33 to rotate. External air enters the heat dissipation box 32 through the heat dissipation hole 34, and the hot air is discharged through the heat absorption hole 35. Meanwhile, the metal heat dissipation strip 4 on the protective cover 2 provides auxiliary heat dissipation. This combination of multiple heat dissipation methods—fan heat dissipation, heat dissipation hole 34 heat dissipation, and metal heat dissipation strip 4 auxiliary heat dissipation—forms an effective air convection circulation, improving the overall heat dissipation effect. The fan motor 31 drives the fan to provide active heat dissipation, and the heat dissipation hole 34 and the heat absorption hole 35 form an effective airflow channel. When the user opens the protective cover 2, the auxiliary handle 8... To open the protective cover 2, first remove the transmission ball 54 on the fixing rod 53 from the annular protective pad 52 on the locking support 51. By rotating the protective cover 2, the protective cover 2 rotates, causing the connecting block 63 to rotate on the rotating shaft 62, making it convenient for the user to plug the plug into the switch body 1. The connecting wire on the plug can pass through the notch 7, reducing the problem of the protective cover 2 being restricted from closing due to the connecting wire. When closing the protective cover 2, rotate the protective cover 2, causing the connecting block 63 to rotate on the rotating shaft 62. The protective cover 2 first contacts the rubber pad 11 on the bracket to buffer the pressure. At the same time, by passing the transmission ball 54 on the fixing rod 53 through the annular protective pad 52 on the locking support 51, the annular protective pad 52 abuts against the transmission ball 54, restricting the opening of the protective cover 2.

[0029] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
