Latest Patents

One of Weijin Li's latest patents is a cleaning robot capable of simultaneously driving a driving wheel and an impeller by a single motor. This innovative design includes a motor output shaft, a driving wheel with a second rotating shaft, and an impeller with a first rotating shaft. A connector links the motor output shaft to the first rotating shaft, while a speed reducer connects the connector to the second rotating shaft. This cleaning robot can move forward and backward and turn using the driving wheel. It allows waste to enter an internal filter element through negative pressure generated by the internal impeller, discharging purified water or air from the equipment. This invention effectively utilizes one motor to drive both the impeller and the driving wheel, enabling them to operate at different rotating speeds.

Another significant patent involves intermediates of Sitagliptin and the preparation process thereof. This patent discloses a method for synthesizing Sitagliptin using chiral amino compounds as raw materials, eliminating the need for chiral asymmetric catalytic hydrogenation and avoiding high-pressure hydrogenation.
