Latest Patent Applications

One of his notable patent applications is for a fan designed for an automatic dispensing device. This fan is configured to generate airflow when a rotor is rotating. The design includes a drive circuit and an electromagnet with at least one electromagnetic coil connected to the drive circuit. The rotor generates airflow, and at least four magnets are arranged on a circle on the rotor, spaced apart by the same angle. The electromagnet is positioned to attract or repel these magnets, and the drive circuit is designed to switch the current direction in the electromagnetic coil to sequentially attract and then repel each magnet as the rotor rotates. Additionally, the fan includes a magnetic element that attracts one of the magnets when the electromagnetic coil is not powered, ensuring that the rotor comes to a halt without any other magnets assuming a position directly under or above the electromagnet. A preferred embodiment of the fan includes a 'floating suspension' to reduce wear and tear over time.

In conclusion, Charles Yao is a promising inventor in the field of automatic dispensing technology, with innovative ideas that could lead to significant advancements in the industry.
