TECHNICAL FIELD

The present disclosure relates to the technical field of hairdressing devices, particularly to a hairdressing device with a universal conductive structure, such as hair curlers and hair straighteners.

BACKGROUND

Hair curlers, hair straighteners, etc. are commonly used hair care devices, which usually comprise handles. The difference is that a hair curler is a combination of a handle and a curling component, while a hair straightener is a combination of a handle and a comb tooth component. Existing such devices are all in independent integral structures. For example, an electric hair curler is a handheld electronic product used to curl hair by perming, and mainly comprises a handle body and a curling body, wherein the handle is provided with a driving motor and a circuit control board, and the curling body is connected to the driving motor through a shaft; when the control button is pressed, the curling body rotates to realize the curling action. Existing hair curlers on the market usually connect the curling body and handle body electrically via a power cord switching tail, which is structurally complex, and cumbersome to assemble and disassemble, resulting in low production efficiency, such as the hair curler disclosed in Chinese utility model patent CN217791841U. Such conductive structures require users to provide multiple tools such as hair curlers and hair straighteners to complete different hair care operations such as curling and straightening, thereby increasing users’ purchase costs significantly, and also increasing production and packaging costs.

Further, said elastic component is a spring or an elastic soft rubber component, and supports the annular conductive body. When an elastic soft rubber component (e.g., silicone) is used, wires can be provided directly to connect the conductive rings to the control circuit board; insulating rings are provided among the floating conductive rings, fixed by the fixing base and separated by the insulating rings.

In particular, the output conductive components are output conductive rings, and the input conductive components are input conductive rings; the output conductive rings are provided in the female socket at the front end of the handle body, and the input conductive rings are provided in the male socket at the rear end of the hairdressing body; after the hairdressing body and the handle body are mated and fixed together, the hairdressing body and the handle body are connected electrically through the contact between the input conductive rings and the output conductive rings.

Further, the number of output conductive rings and the number of input conductive rings are the same, both comprising several turns, and available in a one-to-one corresponding structure; a plurality of insulating rings are provided in the female socket, and the input conductive rings pass through the gaps between the insulating rings and are connected to the output conductive rings.

Alternatively, the output conductive components are output conductive rings, and the input conductive components are conductive needles; several conductive needles are provided in the male socket of the hairdressing body, each conductive needle forms several concentric circles, and 1-4 conductive needles are provided per turn; a reinforcing rib is provided on the side of each conductive needle in an arc-shaped structure, and coincides with the circumference of the corresponding conductive needle.

Alternatively, the output conductive components are conductive needles, and the input conductive components are input conductive rings; the conductive needles are provided in the female socket of the handle body, and the input conductive rings are provided in the male socket of the hairdressing body.

Alternatively, the output conductive components are output conductive rings, and the input conductive components are input conductive rings; the output conductive rings are provided in the female socket at the front end of the handle body, and the input conductive rings are provided in the male socket at the rear end of the hairdressing body. Each input conductive ring is provided with a conductive contact spring that extends and bends towards the handle body; after the hairdressing body and the handle body are mated and fixed together, the hairdressing body and the handle body are connected electrically through the mutual contact between the conductive contact springs of the input conductive rings and the sides of the output conductive rings.

In addition, it also eliminates the need for users to purchase multiple independent products with different functions, and enables users to realize multiple desired functions by providing the same handle with multiple different functional components, thereby reducing their purchasing costs. Moreover, it can also be packaged after unpacking, which is conducive to the miniaturization of the package.
