  • FAN
    Publication number: 20240084810
    Abstract: A fan includes a fan frame and a driving device. The fan frame includes a base, a frame shell and static blades arranged on the periphery of the base. The driving device includes a stator structure and a rotor structure. The stator structure includes a stator magnetic pole group and a bushing. The rotor structure includes a bearing, a shaft, a rotor shell, a magnetic structure, a magnetic shell and blades. The shaft is connected with the rotor shell and disposed through the bearing. The stator magnetic pole group magnetically drives the magnetic structure to rotate the rotor shell. Two ends of the frame shell are configured with two turning portions, respectively. The two turning portions are disposed between parts of the frame shell with different curvatures. A curvature of the first turning portion is larger than a curvature of the second turning portion.

  • Patent number: 11455267
    Abstract: A calibration device includes a main control unit, an interface conversion unit and an electronic load generation unit. The electronic load generation unit provides an electronic load, so that a USB control chip generates a constant load current. The USB control chip uses at least one preset conversion parameter to generate an analog-to-digital conversion value according to the constant load current. The main control unit generates a to-be-calibrated output current according to the analog-to-digital conversion value. The main control unit generates at least one calibrated conversion parameter according to the constant load current and the to-be-calibrated output current. The USB control chip uses the at least one calibrated conversion parameter to generate a calibrated analog-to-digital conversion value, so that an over current protection mechanism is accurately enabled.

  • Patent number: 11449121
    Abstract: The product detection system includes a computing device, at least one power detection instrument and a product detection device. The product detection device includes a processing unit, plural USB-C transmission ports and plural detection connection ports. A product detection method includes following steps. Firstly, at least one USB-C under-test product is connected with the plural USB-C transmission ports, and the at least one power detection instrument is connected with the plural detection connection ports. Then, the USB-C transmission port is set as a first role or a second role. Then, the USB-C transmission port corresponding to the first role is cyclically operated at plural designated voltages under control of the processing unit, and the processing unit issues an output voltage to the USB-C transmission port corresponding to the second role. Then, an operation status of the USB-C under-test product is detected.

  • Publication number: 20120090081
    Abstract: A toilet with bad-odor exhausting mechanism includes a toilet main body having a bowl and a seat. An exhausting mechanism is provided in the toilet main body for exhausting bad odor in the bowl to an outdoor environment, and includes a passage extending around a top of the bowl, a plurality of vents communicating the passage with a space in the bowl, an extension passage extended from an end of the passage to an outer side of the toilet main body, a connecting member connected to another end of the extension passage, an exhaust pipe having an end locked to the connecting member, and an exhaust motor connected to another end of the exhaust pipe. When the exhaust motor is started, bad odor in the bowl is sucked into the passage and exhausted to the outdoor environment via the extension passage and the exhaust pipe.

  • Publication number: 20080178919
    Abstract: An automated awning comprises a main shaft connected to a screw rod through a sleeve by a screw means. The screw rod is driven to activate a first support rod and a second support rod to slide forward or backward sliding motion. A main support bracket is disposed between the main shaft and a second support rod, and a spring is disposed between the main support bracket and the main shaft. There are deep and shallow grooves and a slopped surface within the second support rod; a free rotor and a fixed rotor are inserted therein. A tube body is mounted on a mount and enclosing the first support rod. The tube body is then inserted into an outer tube. As the screw rod drives the first and second support rods forward, a gear teeth strip on one side of said first link rod stretches a spring so as to open a sun roof by extending the second main support rod, the second link rod and the third main support rod; the rotors are retained on the slopped surface for fixing the main support bracket.
