Abstract: This application provides a bullet-screen comment display method, where the bullet-screen comment display method includes: determining bullet-screen comment area basic information corresponding to a target bullet-screen comment from a target picture; identifying an invalid pixel set of the target picture; determining a bullet-screen comment filling area corresponding to the target bullet-screen comment based on the bullet-screen comment area basic information and the invalid pixel set; and filling the bullet-screen comment filling area with the target bullet-screen comment.

Abstract: A ribbon carrier assembly, a welding device, and a welding method for preprocessing between a battery sheet and a ribbon are disclosed. The carrier assembly includes a carrier seat; a carrier body, rotatably connected to the carrier seat; and a driving assembly, connected to the carrier body and configured to control the rotation of the carrier body. At least one operation surface is arranged on the carrier body and is arranged as a curved surface. Adsorption holes are arranged on the operation surface. The battery sheet is adsorbed and fixed to the operation surface by applying a negative pressure to the adsorption holes. Through tins, dry joints between the battery sheet and the ribbon can be reduced during welding of the ribbon and the battery sheet. The battery sheet is bent on the curved surface to avoid warping or cracking of the battery sheet caused by excessive heating.

Abstract: Some embodiments of the present disclosure provides a head shaking device and a fan. The head shaking device includes a fixing assembly; and a rotating assembly, which rotates relative to the fixing assembly in a reciprocating manner, wherein one of the fixing assembly and the rotating assembly includes at least one first connecting structure, the other includes at least one second connecting structure, and the first connecting structure is rotatably clamped with the second connecting structure.

Abstract: Water outlet valve structure and a humidifier having the same. Opening or closing of the water outlet valve structure is controlled by a control structure. The water outlet valve structure includes a flow channel including an inlet and an outlet. The control structure is capable of sealing or opening the outlet of the flow channel. The outlet of the flow channel is capable of being sealed or opened by the control structure of the water outlet valve structure, to control the open and close of the flow channel, thereby simplifying the water outlet valve structure. In a further aspect, since only the outlet is sealed, specific requirements for the structure of the control structure are relatively low, thereby allowing the control structure to be simplified.

Abstract: Some embodiments of the present disclosure provide a water retaining structure and a humidifier with the water retaining structure. The water retaining structure is disposed on a bottom surface of a water tank assembly. The water retaining structure and the water tank assembly are split. The water retaining structure includes a mist collecting portion and a water retaining portion. The mist collecting portion is formed into a mist collecting space. The mist collecting space communicates with a mist outlet tube in the water tank assembly. The water retaining portion is configured to collect water flowing down from the mist outlet tube. The water retaining structure and the water tank assembly are split so that the bottom surface of the water tank assembly is configured as a flat surface, or a height of a structure disposed on the bottom surface is reduced.
