Latest Patents
One of his latest inventions is a cyclonic vacuum cleaner. This device features a main body that includes a cyclonic separating device and a suction device. The cyclonic separating device is designed with a chamber body that has an air inlet and an air outlet. As air flows into the chamber, it swirls along the inner wall, creating a cyclonic separation that effectively separates air from solid particles. This design not only reduces the volume of the vacuum cleaner but also allows for a more compact structure, facilitating easier use and better product design while maintaining effective dust separation.
Another significant patent is for a cyclone separating device of a cleaner. This device consists of an upstream cyclone separating device and a downstream cyclone separating device. The two devices are connected through a gas passage, with the upstream device featuring a first cyclone barrel and the downstream device containing at least one second cyclone barrel. The compact design of this cyclone separating device minimizes its radial size and overall height, making it an efficient solution for modern cleaning needs.
