Abstract: A method for controlling a buck converter is provided. The method includes monitoring an inductor current flowing through an inductor in the buck converter. The method includes controlling the buck converter to operate in a pulse frequency modulation (PFM) mode with intermittent conduction if the inductor current experiences a plurality of cross-zero periods. The method further includes adjusting a power consumption of a component in the buck converter according to the plurality of cross-zero periods of the inductor current, when the buck converter is operating in the PFM mode.

Abstract: A semi-automatic feces shoveling cat litter box, comprises a shell, a cat litter bin, and a feces shoveling component. The shell is arranged on the outer periphery of the cat litter bin, and the middle part of the shell is provided with a first opening for cats to enter into the cat litter bin. One end of the shell is provided with a second opening for the cat litter bin to pass through. Under the action of external force, the shell and the cat litter bin move relatively to each other. The end of the cat litter bin away from the second opening is provided with a waste bin. The feces shoveling component is arranged on the end of the shell near the second opening. One end of the feces shoveling component is hinged to the shell, and another end is provided with a first dentate structure.

Abstract: A liquid guide member is provided. The liquid guide member works in cooperation with a heating member for atomizing an aerosol-forming substrate. The liquid guide member is divided into multiple areas. The area farthest from the heating member is defined as a first area, an area adjacent to the heating member is defined as the i-th area, and the area between the first area and the i-th area is defined as the x-th area, wherein the flow velocity Q of the aerosol-forming substrate in the first to i-th areas satisfies: Q1?Qi, and Q1>Qx, 1<x<i, i being a positive integer and i?2. The liquid guide member, atomizing core, atomizer, and aerosol generating system provided can not only reduce the risk of leakage of the aerosol-forming substrate, but also avoid the occurrence of dry burning, coking, or aerosol insufficiency.

Abstract: A Mason jar sealing device includes: a mounting shell, a connection assembly, and an air pumping-inputting assembly. The mounting shell or the connection assembly defines an air inlet.
