Description

Technical Field

[0001] This utility model relates to an adapter, and more particularly to a dustproof power adapter. Background Technology

[0002] With the increasing popularity and expanding application of electronic devices, power adapters, as key components connecting power supplies to various portable or stationary electronic devices, have become increasingly important in terms of performance and reliability. Traditional power adapters typically focus only on conversion efficiency, safety, and miniaturization. However, in real-world usage scenarios, dust is a factor that cannot be ignored. Dust can not only affect the heat dissipation of the power adapter, leading to overheating failures, but may also cause problems such as short circuits or poor contact in the internal circuitry, thereby shortening the product's lifespan and even posing safety hazards.

[0003] Most existing power adapters are not specifically designed for dust protection. They often adopt an open structure, which, while facilitating heat dissipation, makes it easy for dust particles in the air to enter. This is especially true in certain application environments, such as industrial sites, outdoor work areas, or inside vehicles, where dust concentrations are high. The drawbacks of this open design are even more pronounced in these environments. In addition, traditional power adapters do not have effective protective measures at the interface, making it inevitable that external contaminants will be introduced during plugging and unplugging.

[0004] Therefore, a dustproof power adapter needs to be designed. Utility Model Content

[0005] To overcome the shortcoming that most existing power adapters are not specifically designed for dust protection, the technical problem to be solved is to provide a dustproof power adapter.

[0006] The technical solution is as follows: A dustproof power adapter includes a first protective sleeve, which is fitted onto the power adapter body and is tightly attached to the outer wall of the power adapter body. It also includes baffles, guide blocks, elastic elements, push blocks, return springs, storage blocks, and push strips. Baffles are slidably connected to the left and right sides of the front of the first protective sleeve, both baffles covering the front of the connection port of the power adapter body. Guide blocks are symmetrically slidably connected to the left and right sides of the top of the first protective sleeve, with the sides of the two guide blocks that are close to each other being inclined. Each guide block is connected to a corresponding first protective sleeve... An elastic element is connected between the two sides of the first protective sleeve. A push block is slidably connected to the top center of the first protective sleeve. A groove is provided on the top of the first protective sleeve to allow the push block to slide. The groove can limit the maximum distance of the push block to slide. A pentagonal hole is provided on the front side of the push block. A return spring is connected between the push block and the first protective sleeve. Inclined surfaces are provided on the left and right sides of the push block. The inclined surfaces on the left and right sides of the push block are in contact with the inclined surfaces on the two corresponding guide blocks. A storage block is fixed to the right side of the first protective sleeve. A push strip is slidably inserted into the storage block. There is a certain friction between the push strip and the storage block.

[0007] Furthermore, it also includes a second protective sleeve, a shock-absorbing spring, a sponge pad, and a damper. The second protective sleeve is fitted onto the first protective sleeve. There is a gap between the inner wall of the second protective sleeve and the outer wall of the first protective sleeve. An opening is provided on the upper front side of the second protective sleeve, which is horizontally aligned with the pentagonal slot of the push block. Multiple ventilation holes are provided on the top of the second protective sleeve. Multiple sponge pads are connected to the outer wall of the first protective sleeve. A shock-absorbing spring is connected between each sponge pad and the inner wall of the second protective sleeve. Multiple dampers are connected between the inner wall of the second protective sleeve and the outer wall of the first protective sleeve.

[0008] Furthermore, it also includes a touch sensor, a fan, a controller, a temperature sensor, and an alarm. A touch sensor is installed on the top of the first protective cover, which is located directly behind the push block. Fans are installed on both the front and rear sides of the touch sensor. A controller, a temperature sensor, and an alarm are installed on the rear side of the top of the first protective cover. The alarm light of the alarm extends through the outer wall of the second protective cover. The controller is electrically connected to the touch sensor, the fan, the temperature sensor, and the alarm.

[0009] Furthermore, it also includes a protective sleeve, with the second protective sleeve connected to the middle of its rear side. The protective sleeve is made of soft plastic.

[0010] Furthermore, it also includes anti-collision strips, with anti-collision strips provided on the four rounded corners of the outer wall of the second protective sleeve.

[0011] Furthermore, it also includes a second protective cover made of engineering plastic.

[0012] The beneficial effects of this utility model are as follows: 1. Through the design of the baffle, this utility model can seal the connection interface of the power adapter when not in use, effectively preventing dust and other small particles from entering the inside of the power adapter, greatly extending the service life of the product. When in use, the baffle can be opened by simply pushing the push block backward with a pentagonal wrench or other hard long object. The operation is simple.

[0013] 2. By introducing a temperature sensor, this utility model enables real-time monitoring of the power adapter's operating status, allowing for timely detection and handling of potential safety hazards, such as overheating, thereby improving overall safety. Furthermore, the design of shock-absorbing springs and foam pads enhances its impact resistance and shock absorption, making it suitable for various complex application scenarios.

Detailed Implementation

[0020] The present invention will now be described more fully below with reference to the accompanying drawings, in which presently preferred embodiments of the invention are shown. However, the present invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness and to fully convey the scope of the invention to those skilled in the art.

[0021] Example: A dustproof power adapter, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the power adapter body 1 is fitted with a first protective sleeve 2, which is tightly attached to the outer wall of the power adapter body 1. It also includes a baffle 3, guide blocks 4, elastic elements 5, push blocks 6, a return spring 601, a storage block 102, and a push strip 103. The front left and right sides of the first protective sleeve 2 are slidably connected to baffles 3, which cover the front of the connection port of the power adapter body 1. The top left and right sides of the first protective sleeve 2 are symmetrically slidably connected to guide blocks 4, with the sides of the two guide blocks 4 that are close to each other being inclined. Each guide block 4 is connected to a corresponding side of the first protective sleeve 2 by an elastic element 5. A push block 6 is slidably connected to the top of the protective sleeve 2. The top of the first protective sleeve 2 has a groove for the push block 6 to slide, which limits the maximum distance of the push block 6 to slide. A pentagonal slot is provided on the front side of the push block 6. A return spring 601 is connected between the push block 6 and the first protective sleeve 2. The left and right sides of the push block 6 have inclined surfaces that slope towards the middle. The inclined surfaces on the left and right sides of the push block 6 are in contact with the inclined surfaces on the two corresponding guide blocks 4. A storage block 102 is fixedly connected to the right side of the first protective sleeve 2. A push strip 103 is slidably inserted into the storage block 102. There is a certain friction between the push strip 103 and the storage block 102, so that the push strip 103 will not easily slide out. When in use, the user needs to pull out the push bar 103 inside the storage block 102, and then use the push bar 103 to push the push block 6 backward. When the push block 6 moves backward, the inclined surfaces on both sides will press the guide block 4 to expand outward, the reset spring 601 will be stretched, and the elastic element 5 will be compressed, so that the two baffles 3 slide to both sides synchronously, exposing the power adapter connection port for the user to connect the device.

[0022] like Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, it also includes a second protective sleeve 7, a shock-absorbing spring 8, a sponge pad 9, and a damper 901. The second protective sleeve 7 is fitted onto the first protective sleeve 2. There is a gap between the inner wall of the second protective sleeve 7 and the outer wall of the first protective sleeve 2. The second protective sleeve 7 is made of engineering plastic. Engineering plastic is usually lighter than metal, easy to carry, and has good electrical insulation properties to ensure safe use. The upper front side of the second protective sleeve 7 has an opening that is horizontally aligned with the pentagonal slot of the push block 6. The top of the second protective sleeve 7 has multiple ventilation holes. Multiple sponge pads 9 are connected to the outer wall of the first protective sleeve 2. Each sponge pad 9 is connected to the inner wall of the second protective sleeve 7 with a shock-absorbing spring 8. Multiple dampers 901 are connected between the inner wall of the second protective sleeve 7 and the outer wall of the first protective sleeve 2. The second protective sleeve 7 is connected to the first protective sleeve 2 and the damper 901 via the shock-absorbing spring 8 and the sponge pad 9, forming an effective buffer layer. When the power adapter is subjected to external impact, the shock-absorbing spring 8 first absorbs most of the vibration energy, and then the damper 901 and the soft sponge pad 9 further disperse the remaining force to ensure the safety of the internal components.

[0023] like Figure 4 As shown, it also includes a touch sensor 10, a fan 11, a controller 12, a temperature sensor 13, and an alarm 14. The touch sensor 10 is installed on the top of the first protective sleeve 2. The touch sensor 10 is located directly behind the push block 6. Fans 11 are provided on both the front and rear sides of the touch sensor 10. The fans 11 correspond to the above-mentioned ventilation openings. The controller 12, the temperature sensor 13, and the alarm 14 are installed on the rear side of the top of the first protective sleeve 2. The alarm light of the alarm 14 extends through the outer wall of the second protective sleeve 7. The controller 12 is electrically connected to the touch sensor 10, the fan 11, the temperature sensor 13, and the alarm 14. The touch sensor 10 and the push block 6 are used in conjunction. When the push block 6 is pushed to its end, its rear end will contact the touch sensor 10. When the user plugs in the power connector, the power connection will prevent the baffle 3 from resetting, thus keeping the push block 6 in contact with the touch sensor 10. After receiving the information, the touch sensor 10 will transmit it to the controller 12, which will then start the fan 11 to maintain internal air circulation and effectively cool the device. The built-in temperature sensor 13 continuously monitors the operating temperature of the power adapter. Once the temperature exceeds the preset range, the controller 12 will issue an audible and visual warning signal via the alarm 14 to remind the user to take necessary cooling measures or disconnect the power for inspection.

[0024] like Figure 5 As shown, it also includes a protective sleeve 15. The protective sleeve 15 is connected to the middle of the rear side of the second protective sleeve 7. The protective sleeve 15 is made of soft plastic and is mainly used to protect the power cable from physical damage. It also makes it easy to organize and manage the cable.

[0025] like Figure 1 , Figure 2 and Figure 5 As shown, it also includes anti-collision strips 101. Anti-collision strips 101 are provided on the four rounded corners of the outer wall of the second protective sleeve 7. The anti-collision strips 101 provide additional impact resistance and are suitable for preventing edge damage during transportation or storage.

[0026] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
