Abstract: A dual-flavor electrical cigarette with two stress-reducing cylinders includes a housing, two cartridge assemblies, two pairs of bearing assemblies, and two stress-reducing cylinders; each pair of bearing assemblies comprises a first bearing and a second bearing; the two stress-reducing cylinders are arranged in the housing and respectively contain one of the two cartridge assemblies, two pairs of bearing assemblies respectively correspond with one stress-reducing cylinders, the first bearing and the second bearing are respectively arranged at an upper part and a lower part of the stress-reducing cylinder and movably connected therewith; each stress-reducing cylinder is rotated separately by applying force. The dual-flavor electrical cigarette with two stress-reducing cylinders combines dual-flavors with two rotary stress-reducing cylinders so that a user can rotate the stress-reducing cylinders separately, thereby having interestingness.

Abstract: An electronic cigarette with a stress-reducing part includes a main body with a housing. The outer wall of the housing is provided with a first magnetic element, and the housing is movably connected to a stress-reducing part at an outside of the first magnetic element. The stress-reducing part is provided with a second magnetic element at the side wall facing the housing. The side of the first magnetic element and the side of the second magnetic element that are close to each other attract each other. The number of the first magnetic element and that of the second magnetic element are at least two. When an external force acts on the stress-reducing part, the first magnetic element and the second magnetic element are mutually magnetized or demagnetized so that the stress-reducing part can move back and forth.

Abstract: A low-power low-dropout (LDO) voltage regulator device includes an error amplifier, a level-shifter circuit, and an NMOS pass transistor. The error amplifier compares a sampled portion of a regulated output voltage of the LDO voltage regulator with a reference voltage and generates an error signal. The level-shifter circuit is coupled to the error amplifier. The NMOS pass transistor provides the regulated output voltage with low dropout operation. The level-shifter circuit can shift a voltage level of the error signal to facilitate the low dropout operation of the NMOS pass transistor.
