Description

BACKGROUND

Technical Field

The present invention belongs to the field of hairdressing tools, and particularly relates to a water replenishing assembly for a hair straightener and a water replenishing hair straightener.

Related Art

According to an existing hair straightener, hair is clamped by a high-temperature metal surface or hard resin surface so as to heat the hair and simultaneously straighten the hair. In this process, the hair is damaged in three ways: (1) the hair is burnt by high temperature above 200 °C; (2) the hair softened at high temperature is scratched by the hard metal surface or the hard resin surface; and (3) the water inside the hair is baked at high temperature, and the hair is seriously dehydrated. The straightened hair is straighter but is hard, dry, split, more static and tarnished. Therefore, chemical liquid needs to be smeared on the surface of the hair before the hair is straightened so as to form a protective film, and simultaneously, the straightened hair needs to be softened by using chemical liquid.
The existing technologies are provided with some vapor hair straighteners. However, an electric heating mode is mainly used for boiling water to generate vapor, the temperature of the vapor is too high, and the vapor cannot directly form water drops. Simultaneously, when a vapor hair straightener is used for straightening the hair, the vapor easily scalds scalp or hands; and water cannot fully form mist and cannot fully enter the hair scales of the hair, so that the hair cannot be replenished with water, and the hair cannot be nursed.
CN203618965U discloses an atomized vapor hair straightener using ultrasonic atomization sheets. However, the heating time of the hair straightener is longer, the temperature of the hair straightener cannot rise to the working temperature within a short time, and long-time ultrasonic atomization enables the water of the hair to be atomized in advance in the straightening process.
Document CN205 492 912 discloses a water replenishing assembly for a hair straightener.
Therefore, a hair straightener capable of realizing quick temperature rise and water replenishment needs to be designed.

SUMMARY

Technical problems
