[0028] Refer to Figures 1 - 5, according to an embodiment of a hollow hair straightener of the present utility model, it includes a connecting portion 11. A lower clamping plate 12 is integrally formed on the right side of the connecting portion 11. An upper clamping plate 13 is also hinged on the right side of the connecting portion 11. Heating plates 14 that are distributed front and back and extend left and right are respectively provided on the sides of the lower clamping plate 12 and the upper clamping plate 13 that face each other. Users can place their hair between the lower clamping plate 12 and the upper clamping plate 13, and press the upper clamping plate 13 onto the lower clamping plate 12 and drag it. At this time, the hair will contact the heating plates 14 and perform a hair straightening operation. The heating plates 14 distributed front and back will perform two hair straightening operations;

[0029] In addition, in order to improve the hair straightening effect, a through groove 15 that penetrates up and down is respectively provided in the lower clamping plate 12 and the upper clamping plate 13. The through groove 15 is located between the heating plates 14 in the front and back. The design of the through groove 15 allows the hair to cool down before the user performs a hair straightening operation through the heating plates 14 in the front and back, achieving a better hair straightening effect.

[0030] In order to avoid burning hands, the installation scheme of the installation groove 16 is as follows: Installation grooves 16 for accommodating and fixing the heating plates 14 are respectively provided in the lower clamping plate 12 and the upper clamping plate 13. The installation grooves 16 are respectively provided on the front and back sides of the through groove 15. A boss 17 is provided on the bottom surface of the installation groove 16. A heat dissipation groove is provided in the boss 17, and protruding columns 18 distributed left and right are provided in the boss 17. The protruding columns 18 abut against the heating plates 14. The design of the protruding columns 18 prevents the heating plates 14 from contacting the boss 17 and prevents the heat from the heating plates 14 from being transferred to the back surfaces of the lower clamping plate 12 and the upper clamping plate 13 when the heating plates 14 are energized, avoiding burning hands. In addition, in order to increase the heat dissipation effect, the heat dissipation groove extends left and right and is distributed front and back after winding around the protruding columns 18.

[0031] In order to facilitate assembly, the heating plate 14 includes a heating portion 91 and end portions 92 provided at the left and right ends of the heating portion 91. A clamping plate 93 is provided at one end of the end portion 92 away from the heating portion 91;

[0032] The installation groove 16 penetrates outward, and a card slot is provided at the right end of the installation groove 16. The clamping plate 93 on the end portion 92 on the right side of the heating portion 91 is inserted into the card slot;

[0033] The lower clamping plate 12 and the upper clamping plate 13 are provided with an inner cavity 19 communicating with the installation groove 16. The inner cavity 19 is closed by a cover plate 20, and the clamping plate 93 on the end portion 92 to the left of the heating portion 91 is pressed by the cover plate 20. A circuit board 21 for controlling the heating plate 14 is installed in the inner cavity 19, and buttons connected to the circuit board 21 are provided on both the lower clamping plate 12 and the upper clamping plate 13. The method of controlling the power of the heating plate 14 by the buttons through controlling the circuit board 21 is a prior art and will not be elaborated here.

[0034] In the second embodiment of the hollow hair straightener, in order to facilitate the user to spray styling spray, hair care essential oil or other liquids on the hair during the hair straightening process, a liquid dispenser 22 that can be installed on the upper clamping plate 12 is further included. The liquid dispenser 22 includes a box body 31. A liquid storage cavity 32 is provided in the box body 31. The box body 31 is further provided with an extension plate 33 adapted to the shape of the through groove 15. An atomizing nozzle 34 is installed in the extension plate 33, and a pressurizing mechanism for atomizing and spraying the liquid in the liquid storage cavity 32 through the atomizing nozzle 34 is provided in the box body 31. A clamping mechanism for fixing on the lower clamping plate 12 so that the extension plate 33 enters the through groove 15 is provided in the box body 31.

[0035] In this embodiment, the pressurizing mechanism includes a piston plate 41 slidably connected left and right in the liquid storage cavity 32. An internal thread sleeve is further provided on the side surface of the piston plate 41. A motor 42 is installed in the box body 31, and an output shaft extending from the motor 42 is threadedly connected to the internal thread sleeve. A flow channel communicating with the atomizing nozzle 34 is provided in the side surface of the liquid storage cavity 32, and the flow channel is outside the stroke of the piston plate 41. When the motor 42 is powered on, it will drive the output shaft to rotate, thereby causing the piston plate 41 to move up and down. When the piston plate 41 moves in the direction of the flow channel, the liquid in the liquid storage cavity 32 will be sprayed out through the atomizing nozzle 34 under pressure. If the user is performing a hair straightening activity at this time, the liquid sprayed out through the atomizing nozzle 34 can contact the user's hair during the hair straightening process to care for the hair, reduce hair damage during the hair straightening process, or be used for shaping the hair.

[0036] The clamping mechanism includes two chutes distributed left and right in the box body 31. Hook plates 51 are slidably connected left and right in the chutes, and the hook plates 51 are connected to the side surfaces of the chutes by springs so that the left and right hook plates 51 tend to move away from each other;

[0037] A finger pressure plate 52 is integrally formed on the upper side of the hook plate 51, and the pressure plate 52 extends to both sides of the box body 31. The user can press the pressure plate 52 inward with two fingers to disassemble or install the liquid dispenser 22. When the liquid dispenser 22 is in the installed state, the hook plate 51 can hook on the side of the upper clamping plate 13 close to the lower clamping plate 12 to fix the liquid dispenser 22.

[0038] In addition, in order to facilitate the user to control the motor 42, a connection port 53 is provided in the upper side surface of the upper clamping plate 13, and a socket for connecting to the connection port 53 to control and supply power to the motor 42 is provided on the liquid dispenser 22. When the liquid dispenser 22 is fixed by the clamping mechanism, the socket can be inserted into the connection port 53, so that the user can control the motor 42 by pressing a button located on the lower clamping plate 12 or the upper clamping plate 13.

[0039] Moreover, a liquid injection hole communicating with the liquid storage cavity 32 is provided in the liquid dispenser 22, and a plug plate is arranged in the liquid injection hole to keep the liquid storage cavity 32 sealed.

[0040] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any changes or modifications made by those skilled in the art within the scope of the present invention are covered by the patent scope of the present invention.
