Patent ID: 8646287

Claim:
An electronic apparatus comprising: a housing defining an accommodating space therein, and an air inlet that places said accommodating space in fluid communication with the external environment; and an airflow regulating device including a cover panel for covering and uncovering said air inlet, and an actuating mechanism coupled to said cover panel and driving movement of said cover panel to adjust the degree of opening of said air inlet in response to a change in temperature in said accommodating space; wherein said airflow regulating device further includes a motor controller for controlling operation of said actuating mechanism to drive movement of said cover panel; wherein said airflow regulating device further includes a temperature sensor, a keyboard controller, and a temperature-controlling circuit coupled to said temperature sensor, said keyboard controller, and said motor controller, said temperature sensor detecting the temperature in said accommodating space and generating a temperature detection value corresponding to the temperature in said accommodating space, said keyboard controller being configured with different temperature settings, said temperature-controlling circuit being operable to receive said temperature detection value from said temperature sensor, transmit said temperature detection value to said keyboard controller, and receive a corresponding set value of one of said temperature settings from said keyboard controller, said temperature-controlling circuit generating a driving voltage corresponding to said corresponding set value to control operation of said motor controller; wherein when said driving voltage generated by said temperature-controlling circuit corresponds to a preset value established in said motor controller, said motor controller generates a control signal to control operation of said actuating mechanism to drive movement of said cover panel and thereby open said air inlet; wherein said cover panel is pivotably connected to said housing and is provided with a first hook element, said actuating mechanism including a second hook element mounted on said housing and engaging releasably said first hook element, and an urging spring for urging said cover panel to move relative to said air inlet from the closed position to an open position.
