Description

[Technical field]

[0001] The present application relates to the field of beauty and hairdressing, and in particular to a photothermal hairdressing device. [Background technology]

[0002] Curling irons and hair straighteners on the market currently generally use PTC and MCH heating methods (PTC and MCH are both ceramic heating methods, which are currently commonly used heating methods for curling irons and hair straighteners) to curl or straighten hair. This heating method heats the aluminum rod or aluminum sheet and then transfers the heat to the hair, causing the hair to deform after reaching a certain temperature. During the heating process, the heat of the metal material is directly transferred to the hair, and the heated temperature of the hair is high and difficult to control. During the heating process, the hair is in a heated state for a long time, which causes great damage to the hair cuticle and medulla. During the continuous heating process, the water in the hair evaporates greatly, seriously affecting the hair quality and glossiness. [Utility Model Content]

The preferred angle is between 15 and 60°. The penetration angle is the wind outlet angle. The output low-temperature airflow can cool the hair wrapped around the outer periphery of the rod body 202. The angle selected between 15 and 60° can make the wind flow evenly through the hair wrapped around the surface of the rod body, and the flow rate will not be too slow, so the hair can be cooled efficiently and evenly. The direction in which the air outlet hole 212 penetrates the side wall of the rod body 202 can be a direction tangent to the inner wall of the rod body 202. The air outlet hole 212 extends axially and multiple air outlet holes 212 are arranged in an array along the circumferential direction, such as Fig. 27 As can be seen from the wind outlet schematic diagram, the direction in which the air outlet holes 212 penetrate the side wall of the rod body 202 is staggered in the clockwise direction relative to the radial direction, and the air outlet holes 212 form a clockwise rotating wind outlet effect.

The angle between the direction in which the air outlet 214 extends along the longitudinal direction of the rod body and the axis of the rod body is 0° to 70° or 0° to -70°. In addition, the air outlet holes 214 may be straight grooves or arc grooves. After the multiple air outlet holes 214 penetrate the rod body 204, the arrangement manner presented on the outer peripheral surface of the rod body may be an inclined straight line arrangement array, an arc arrangement array, or a spiral arrangement array.

[0082] The photothermal hairdressing device of the present application heats the curled hair and then cools it down with a cooling and ventilation design. The combination of rapid heating and rapid cooling can achieve rapid temperature difference shaping.

[0083] In some embodiments, a filter element is provided before the light source emits light; or a filter film is coated on the surface of the lamp tube 300 or the inner surface of the tube body or the outer surface of the tube body; or a filter film is provided between the tube body and the light source; or the tube body uses a filter crystal. The photothermal hairdressing device of the present application can also use light waves of different bands to perform physical therapy on the hair / scalp. The realization of different bands can be achieved by replacing light sources that can emit different bands, or by filtering and selecting light through a filter element before the light source emits light, or by coating the surface of the lamp tube 300 to select the required single band (such as 900-1800nm ​​or 380-450nm or 600-750nm), or by coating multiple bands: selecting two or more light wave intervals (such as 38 0-450nm+900-1800nm), coating different bands of films on the surface of the lamp tube 300 in different directions, or coating different bands of films on the surface of different positions along the axis of the lamp tube 300; or coating on the tube body, or selecting a filterable crystal as the tube body, you can choose the required single band (such as 900-1800nm ​​or 380-450nm or 600-750nm), or choose two or more light wavelength intervals to coat multi-band films (such as 380-450nm+900-1800nm). Different bands of light waves have different phototherapy effects on hair / scalp, for example, near infrared band 900-2500nm, red light 600-750nm light wave, 420nm light wave.

[0084] The photothermal hairdressing device of the present application adopts the photothermal effect, using the thermal energy of light and the spatial radiation addition method, eliminating the problem of conduction and conduction efficiency of the intermediate medium, so that the hair is quickly and instantly heated to achieve a curly / straight hairdressing effect; the light source heating is not easy to burn the hair.

[0085] In addition, the cooling effect can be combined. After using the photothermal hairdressing device to heat the curled hair, the blowing mode is turned on. The blowing component drives the air to circulate in the ventilation path and blows cold air toward the hair, which can quickly lower the temperature of the hair and cause a rapid temperature difference from hot to cold in the curled hair, which is beneficial to hair styling.

[0086] Light waves of different bands have different phototherapy effects on the hair / scalp, such as near-infrared band 900-2500nm, red light 600-750nm, and 420nm.

Any equivalent transformation based on the technical solution of the present application belongs to the protection scope of the present application.
