  • Publication number: 20240090640
    Abstract: A hair pressing device and a hair curler are provided and specifically relate to a technical field of hairdressing devices. The hair pressing device includes a heating assembly having a diameter being adjustable and a plurality of hair pressing sheets disposed on a periphery of the heating assembly in a radial direction of the heating assembly. Each of the plurality of the hair pressing sheets includes a deformation position in an axial direction of the heating assembly, so that each of the plurality of the hair pressing sheets is bent at a corresponding deformation position when a gap between the heating assembly and each of the plurality of the hair pressing sheets is reduced or an amount of hair is increased.

  • Publication number: 20230346097
    Abstract: The invention relates to hairdressing equipment and discloses a pressing transmission device and curler. The pressing transmission device comprises a housing assembly, a movable or rotatable pressing assembly in the housing, a connecting rod assembly having a first moving end connected to the pressing assembly, driven by it, and a second moving end connected to a reversing assembly. The reversing assembly has a moving part connected to the second moving end and a rotating part matched with the moving part, which converts the movement of the connecting rod assembly into the rotation of the rotating part. The connecting rod assembly and the reversing assembly are both provided in the housing assembly. The structure of the pressing transmission device provided is simple, and the rotation of the rotating part can be achieved by pressing the pressing assembly, which is convenient in operation.

  • Patent number: 11728605
    Abstract: The present invention discloses a rotary electrical connection assembly. The rotary electrical connection assembly includes: a fixed part disposed fixedly and a rotating part disposed rotatably relative to the fixed part. The rotating part is provided with at least two rotary contacts. In the rotary electrical connection assembly provided in the present invention, provided that more groups of the rotary contacts and the fixed contacts are disposed, at least some of the contacts may be disposed at different radial positions corresponding to the same axial position without additionally occupying an axial dimension space, and therefore the increase of an axial dimension of a device may be avoided, and miniaturization of the device is facilitated.
