Abstract: An iridium complex for an organic light-emitting device includes the chemical structural formula shown below, where the ring A is selected from C12-C30 polycyclic groups formed by fusing three or more monocyclic groups with each other, and the precondition is that the ring A at least includes the structure of general formula II: R1-R5 are the same or different, and each independently is H, deuterium, halogen, —CF3, CN, amino, substituted or unsubstituted C1-C10 alkoxyl, or substituted or unsubstituted C1-C30 alkyl, hydrogens on the alkyl chain of the C1-C10 alkoxyl and C1-C30 alkyl may each be independently substituted by deuterium, halogen, —CF3 or CN, where the halogen is selected from fluorine, chlorine, bromine or iodine; Rx and Ry are the same or different, and each independently includes saturated aliphatic ring structure. The iridium complex has excellent red-light saturation, luminous efficiency and thermal stability.

Abstract: A shower plug bracket and a moving assembly are provided. The shower plug bracket includes a base and a plug bracket portion. The plug bracket portion is configured to rotate up and down to adjust a use angle, the two cooperate with a locking structure, the locking structure includes a first component and a second component, the first component is connected to the base, the second component is disposed on the plug bracket portion, the first component is disposed with first teeth, the second component is disposed with second teeth, and the first teeth are engaged with the second teeth. When the plug bracket portion rotates upward or downward, the first teeth of the first component are disengaged from the second teeth of the second component. When the plug bracket portion stops rotating, the first teeth and the second teeth reset to an engaged state.

Abstract: A skin-beautifying shower device includes a toiletries container and a switching assembly provided in a handle. The toiletries container includes a housing and a storage tube. The housing is provided with a water inlet end and a water outlet end. The storage tube is placed in the housing with at least one end thereof being enclosed, and a gap is defined between the outer wall of the storage tube and the inner wall of the housing to form a first water passage communicating with the water inlet end and the water outlet end. The switching assembly includes a rotating disc, a water splitter piece, and a toggle. The rotating disc is provided with a first water outlet hole communicating with the first water passage. The water splitter piece is provided with a second water outlet hole communicating with the water outlet. The toggle extends out of the handle and drives the rotating disc to rotate and to control a communication area between the first and second water outlet holes.

Abstract: The present disclosure discloses a shower plug bracket and a moving assembly. The shower plug bracket comprises a base and a plug bracket portion. The plug bracket portion is configured to rotate up and down to adjust a use angle, the two cooperate with a locking structure, the locking structure comprises a first component and a second component, the first component is connected to the base, the second component is disposed on the plug bracket portion, the first component is disposed with first teeth, the second component is disposed with second teeth, and the first teeth are engaged with the second teeth. When the plug bracket portion rotates upward or downward, the first teeth of the first component are disengaged from the second teeth of the second component. When the plug bracket portion stops rotating, the first teeth and the second teeth reset to an engaged state.

Abstract: Provided is a hair cutting assembly. The hair cutting assembly includes at least one first shearing wheel, first transmission shaft that drives the first shearing wheel to rotate, at least one second shearing wheel and second transmission shaft that drives the second shearing wheel to rotate. Opposite end surfaces of each first shearing wheel and the corresponding second shearing wheel are attached to each other. The first cutting blades, formed by intersecting end surface of the first shearing wheel with side wall, and the second cutting blades, formed by intersecting end surface of the second shearing wheel with side wall, oppositely move in a feed direction, such that long and thin linear sundries such as hairs and fabrics can be continuously shorn. A floor drain with the hair cutting assembly is also provided.
