Description

Technical Field

[0001] This application relates to the technical field of card readers, and in particular to a card reader that uses a built-in fan for heat dissipation. Background Technology

[0002] A card reader is an interface device used in computers to read and write multimedia cards as mobile storage devices. Card readers typically connect via USB and can access various memory card formats, such as CompactFlash and Secure Digital. Commercial versions of card readers can read security smart cards. Card readers are categorized by memory card type, including IC card readers, CF card readers, SM card readers, PCMICA card readers, and Memory Stick readers / writers. Dual-slot card readers can also be used to read two or more types of cards simultaneously. They are also categorized by port type, including serial port card readers, parallel port card readers, and USB card readers.

[0003] Modern card readers support high-speed data transmission (such as UHS-II, UHS-III, PCIe, etc.), and these interfaces generate a lot of heat during high-speed read and write operations. High temperatures can affect the performance of card readers, leading to decreased transmission speeds, increased data error rates, and even potential hardware damage. Cooling card readers using dual fans and heat sinks is an effective thermal management design aimed at ensuring that the card reader maintains a suitable operating temperature under high loads or prolonged operation, thereby improving its performance and reliability.

[0004] Regarding the aforementioned technologies, the inventors have discovered the following deficiencies: In the prior art, there is a lack of a dustproof mechanism. During the heat dissipation process of the fan inside the card reader, external dust will enter the card reader through the air intake, thereby damaging the internal components of the card reader. In order to solve the deficiency of the lack of a dustproof mechanism in the prior art, this application uses components such as a filter and a cleaning brush to filter and clean the dust that enters the card reader body, thereby achieving a dustproof effect.
