Moreover, the graphene heating coating has high heating efficiency and a large heating area, does not require too high a heating temperature, can prevent burns and reduce damage to the hair caused by high-temperature styling.

[Specific implementation method]

[0023] The technical features of the present invention are further described in detail below with reference to the accompanying drawings so that those skilled in the art can understand them.

[0024] An attachment for a negative pressure adsorption curling iron, such as Figures 1-6 As shown, it includes a rod body main part 1, on which are provided several rows of wind guide plates 2 that are inclined upward and arranged in a spiral shape as a whole, a sleeve 3 is nested on the rod body main part 1 and at the outer end of the wind guide plates 2, and on the sleeve 3, corresponding to each row of the wind guide plates 2, there is provided an air outlet slit 4 located at the end of the air guide plates 2, and the air outlet directions of several of the air outlet slits 4 are arranged in a spiral radial manner as a whole, and on the sleeve 3 and at the outer side of the air outlet slit 4, there is provided a cross-sectional convex strip 5 for forming a negative pressure zone, and the cross-sectional convex strip 5 is an outwardly protruding arc surface, and at the inner upper end of the rod body main part 1, there is provided an air equalizing plug-in 6 for balancing the wind pressure inside the rod body main part 1; the accessory needs to be fixedly installed on the main unit when used, and the curling iron using the accessory only needs to be close to the hair when used, and the hair will be evenly rolled to the outer surface of the sleeve 3 by the adsorption force generated by the negative pressure zone, and the hair will be curled and shaped by the hot air and the temperature of the sleeve 3 itself; the main unit generates The airflow is blown in from the connecting port 16 at the bottom end of the rod main part 1, and the airflow in the rod main part 1 is blown out from the air outlet slit 4 in a spiral upward manner through the guidance of the air guide plate 2. When the airflow blown out from the air outlet slit 4 reaches a certain wind speed, a negative pressure area will be formed near the cross-sectional ridge 5, so that the surface of the sleeve 3 generates an adsorption force. At the same time, since the wind equalizing plug-in 6 can balance the wind pressure at the upper and lower ends of the rod main part 1, the wind speed of the airflow when it is blown out from the air outlet slit 4 is basically the same, and the adsorption forces generated at the upper and lower ends of the sleeve 3 are relatively balanced. The upper and lower ends of the accessory can evenly adsorb and wrap the hair, so that more hair is evenly adsorbed and wrapped around the entire sleeve 3, thereby effectively improving the efficiency of curling hair; moreover, the spiral upward airflow blown out from the air outlet slit 4 can make the hair regularly and evenly wrapped around the sleeve, avoiding the entanglement of the hair, so that the curling rod can be easily pulled out of the hair.

[0025] Specifically, the angle of inclination of the same column of the air deflector 2 gradually increases from the bottom end of the rod body main part 1 to the top end of the rod body main part 1. Generally, the inclination angle of the air deflector 2 at the lowermost end of the rod body main part 1 is not less than 30°, and the inclination angle of the air deflector 2 at the uppermost end is not more than 75°. The air deflector 2 with gradually increasing inclination angle can better guide the gas to form a spiral upward airflow, avoid the entanglement of hair, and facilitate the separation of the curling iron from the hair.

[0026] In addition, the air equalizing insert 6 is inverted and conical, and the cross-sectional diameter of the air equalizing insert 6 gradually decreases from the top end of the rod body main part 1 downward. The inverted conical air equalizing insert 6 can gradually reduce the internal space at the upper end of the rod body main part 1, thereby gently enhancing the air pressure at the upper end of the rod body main part 1, achieving the purpose of balancing the air pressure at the upper and lower ends inside the rod body main part 1.

[0027] Specifically, the surface of the sleeve 3 is coated with a graphene heating coating for heating the airflow and the sleeve 3 itself to facilitate rapid styling of the hair. The material of the sleeve 3 is generally stainless steel, aluminum alloy, ceramic, etc. for easy coating processing. The graphene heating coating generally includes a graphene coating for heating and first and second insulating coatings on both sides. An electrode sheet for power supply is also provided at both ends of each graphene coating. The graphene heating coating can replace the existing heating device of the curling iron to heat the airflow to generate hot air. Since the graphene heating coating is directly coated on the sleeve 3 and is closer to the air outlet gap 4, it can achieve precise control of the temperature of the airflow. At the same time, the graphene heating coating can also heat the sleeve 3 itself. When the hair is adsorbed and wound onto the sleeve 3 by negative pressure, the temperature of the surface of the sleeve 3 can be directly transmitted to the hair to accelerate the styling of the hair, thereby effectively improving the curling effect and efficiency. Moreover, the graphene heating coating has high heating efficiency and low energy consumption, and does not need to set a high heating temperature during use, which can prevent burns and reduce damage to the hair caused by high-temperature styling.

[0028] Specifically, an upper cover 10 fixedly connected with the rod main body 1 is arranged at the upper end of the rod main body 1 and above the sleeve 3, a clamping plate 8 extending outward is arranged at the upper end of the air equalizing plug 6, a clamping ring 9 for abutting against the clamping plate 8 is correspondingly arranged at the top end of the rod main body 1, the clamping plate 8 and the clamping ring 9 have the function of installation and positioning, so that the air equalizing plug 6 can be accurately installed on the central axis of the rod main body 1, so as to ensure the balance of air pressure around the air equalizing plug 6, a fixing hole 7 for screwing is arranged at the center of the top end of the air equalizing plug 6, a through hole 11 for screwing through is arranged at the center of the upper cover 10 and corresponds to the fixing hole 7, a cap 14 for preventing air flow from leaking from the through hole 11 is arranged at the top end of the upper cover 10 and above the through hole 11, the air equalizing plug 6 is fixedly installed below the upper cover 10 by screwing through the through hole 11 into the fixing hole 7, and the cap 14 is tightly inserted into the upper cover 10, so that production and assembly are convenient and fast.

[0029] In addition, a plurality of insertion grooves 12 corresponding to the cross-section convex strips 5 are arranged on the inner wall of the upper cover 10, and a positioning piece 13 is arranged in the insertion groove 12, the upper cover 10 is tightly inserted into the sleeve 3, and when assembling, the relative positions of the positioning piece 13 and the cross-section convex strips 5 need to be aligned first, then the upper cover 10 and the sleeve 3 are relatively rotated until the positioning piece 13 abuts against the inner wall of the sleeve 3 to achieve tight fit.

[0030] Specifically, a base 15 for installing and connecting a curling iron main machine is arranged at the lower end of the rod main body 1, a connecting port 16 is arranged at the bottom end of the base 15, and a plurality of clamping blocks 17 uniformly arranged are arranged on the outer wall of the connecting port 16, the accessory is fixedly connected with the main machine through the base 15 and the connecting port 16, and the clamping blocks 17 can facilitate the assembly between the accessory and the main machine.
