Description

Technical Field

[0001] The utility model relates to the technical field of computer adapters, in particular to a multifunctional computer adapter. Background Art

[0002] A computer adapter, also known as a laptop power adapter or charger, is a device that converts grid voltage into a voltage and current suitable for a laptop. As a primary laptop accessory, computer adapters present some issues during use. For example, computer adapters can generate heat during use, which accelerates the aging of electronic components and reduces the lifespan of the adapter. To address this issue, some computer adapters install fans and vents on their outer casings to allow internal air circulation, thereby reducing the temperature of the adapter during use. However, since the adapter is connected to the outside, dust can easily enter the interior. The dust that enters the interior will rub against each other under the blowing of the fan, generating static electricity. Static electricity can damage the circuit boards and electronic components inside the adapter, affecting the normal use of the computer.

[0003] For example, a multifunctional computer adapter disclosed in application number 201620589082.2 includes an adapter body, a fan device body and a retractable wire device disposed within the adapter body. The fan device includes a rotating motor mounted on the inner wall of the adapter body, a rotating shaft connected to the side of the rotating motor away from the adapter body, and a retractable wire device including a wire box, a rotating shaft disposed on one side of the wire box, and a first gear connected to the end of the rotating shaft away from the wire box. The automatic heat dissipation computer adapter of the utility model is configured to automatically activate the fan device body when the temperature rises, thereby reducing the temperature of the adapter and protecting components and wiring within the adapter, thereby preventing damage to high-temperature components and fire caused by aging wiring. The retractable wire device is configured to retract the power cord when not in use, saving space and preventing damage to the wiring caused by human intervention. Although this patent provides heat dissipation through the fan, the fan opening communicates with the interior of the adapter, allowing dust to easily enter the adapter and damage the adapter. Furthermore, this patent also provides a wire retracting function, but the wire retracting device is located within the adapter body and has a complex structure, making it difficult to repair if damaged, which affects user experience.
