  • CORD WINDING ASSEMBLY WITH FINE ADJUSTMENT AND CORRECTION AND WINDOW BLIND USING SAME
    Publication number: 20230013337
    Abstract: A window blind includes a headrail, two lift cords, a blind body, a bottom rail, and two cord winding assemblies that are respectively installed on two opposite sides of the long axis of the bottom rail. The other ends of the lift cords are respectively tied to respective adjustment columns of the cord winding assemblies. When the window blind is folded or stretched, unfortunately, when the winding stroke is inconsistent, the blind body is not folded uniformly or skewed, and the adjustment column of the cord winding assembly on one side can be finely adjusted, so that one of the lift cords is gradually wound and covered on the adjustment column, and indirectly drives the bottom rail and the blind body to gradually adjust to substantially parallel to the bottom of the headrail, thereby effectively achieving the effect of fine-tuning and correcting the blind body.

  • INTERNET OF THINGS DEVICE AND BATTERY POWER SUPPLY CIRCUIT THEREOF
    Publication number: 20230020200
    Abstract: The disclosure provides an Internet of things device and a battery power supply circuit thereof. A voltage of a battery is compared with a predetermined over-discharge voltage to generate a comparison signal. A battery protection circuit serves as a power supply path from the battery to a load and determines whether to cut off the power supply path according to the comparison signal. The battery protection circuit cuts off the power supply path when the voltage of the battery decreases from a value greater than the predetermined over-discharge voltage to a value less than the predetermined over-discharge voltage, but does not turn on the power supply path when the voltage of the battery increases from a value less than the predetermined over-discharge voltage to a value greater than the predetermined over-discharge voltage.

  • AIR STERILIZING DEVICE
    Publication number: 20230001040
    Abstract: An air sterilizing device has a casing, a wheel disc covered with microporous structures, a blower, and a sterilizing module. The casing has an air inlet and an air outlet. The blower located in the casing introduces the external air from the air inlet, and the external air is filtered and sterilized by the wheel disc and the sterilizing module. The filtered and sterilized air is discharged from the air outlet. The sterilizing module locates next to the wheel disc for sterilizing the air flowing through the sterilizing module and also for sterilizing the wheel disc by the relative rotation between the wheel disc and the sterilizing module. Bacteria and viruses attached to the wheel disc are eliminated, and the filtration and sterilization functions of the wheel disc are maintained. The efficacy and the efficiency of the air sterilizing device are therefore improved.
