[0046] Please see Figure 1-25As shown, this utility model relates to a tool for straightening and curling hair with hot air, which can be used for both straightening and curling hair simultaneously. It includes a handle 4, with an accessory head detachably or fixedly connected to the air outlet end of the handle 4. The accessory head includes a curling section 1 for drying and curling hair, a connector 2, and a straightening comb assembly 3 for heating hair to help straighten it. The connector 2 is detachably mounted on the handle 4. The curling section 1 is fixedly mounted on the connector 2. The straightening comb assembly 3 is fixedly disposed on one side of the curling section 1. The connector 2 is either part of the curling section 1 or an independent component separate from the curling section 1. The connector 2 is detachably or fixedly mounted on the handle 4.

[0047] Example 1:

[0048] In this first embodiment, the accessory head is cylindrical in shape, with a curling area A and a straightening area B formed on the circumference of the cylinder. The curling area A is located on the curling part 1, and the straightening area B and its metal heat-conducting comb teeth 32 are located on the straightening comb assembly 3. The curling area A is provided with a hot air outlet and several elastic comb teeth 14 that can grip and hold the hair, and is used to wrap the hair and heat and curl it. The straightening area B is provided with heat-conducting rigid metal heat-conducting comb teeth 32, and is used to comb, heat and straighten the hair. The hot air heat-conducting arc surface 124 formed by the curling area A and the high-temperature heat-conducting arc surface 3212 formed by the straightening area B together form a cylindrical surface. The cross-sectional arc length L of the hot air heat-conducting arc surface 124 is greater than the cross-sectional arc length M of the high-temperature heat-conducting arc surface 3212, and 3≤L / M≤5. The preferred ratio is L / M=4, meaning the ratio of the cross-sectional arc length L of the hot air heat-conducting arc surface 124 to the cross-sectional arc length M of the high-temperature heat-conducting arc surface 3212 is between 3 and 5, with a preferred ratio of 4.

[0049] Combination Figures 23 to 25 As shown, when curling hair, the hair will wrap around and cover a large portion of the heating surface. Depending on the needs, the hair may wrap around and cover the entire hot air heat-conducting arc surface 124 and even the high-temperature heat-conducting arc surface 3212. However, when straightening hair, the hair only needs to slide across the high-temperature heat-conducting arc surface 3212, and the area covered by the hair is smaller. Therefore, setting the cross-sectional arc length L of the hot air heat-conducting arc surface 124 to be greater than the cross-sectional arc length M of the high-temperature heat-conducting arc surface 3212 is more conducive to the needs of use.

[0050] The curling area A is located on the curling part 1 of the accessory head. The hot air conducting arc surface 124 formed by the curling area A is provided with a plurality of racetrack-shaped air outlets 122. The racetrack-shaped air outlets 122 are arranged in an array on the hot air conducting arc surface 124 of the curling area A. Elastic comb teeth 14 are provided between adjacent racetrack-shaped air outlets 122. The handle 4 is connected to the curling part 1 through the connector 2. The handle 4 sends fluid from the connector 2 into the curling part 1 and then flows out through the racetrack-shaped air outlets 122. The plurality of elastic comb teeth 14 enable the hair to wrap around the hot air conducting arc surface 124 of the curling area A of the curling part 1. The racetrack-shaped air outlets 122 output hot air or cold air to soften, style or set the hair.

[0051] The straightening area B is disposed on the straightening comb assembly 3. The straightening comb assembly 3 is fixedly disposed on one side of the curling section 1. Specifically, a groove 115 is provided on one side of the curling section 1 along its length. The bottom of the groove 115 extends from the curling section 1 to a support platform 15. The straightening comb assembly 3 is slidably installed in the groove 115 and abuts against the support platform 15. The straightening comb assembly 3 includes a heat insulation protective cover 31, heat-conducting metal comb teeth 32, a heating element 33, and a pair of heat-conducting plates 34. The heat insulation protective cover 31 contains... The device has a receiving cavity 312, into which the metal heat-conducting comb teeth 32 extend. The heat-conducting sheet 34 is disposed in conjunction with the heating component 33 within the metal heat-conducting comb teeth 32. The heating component 33 is electrically connected to the control circuit board 43 inside the handle 4 via conductive leads. In this embodiment, the heating component 33 is connected to the first power terminal 18 via conductive leads. The first power terminal 18 is disposed inside the connector 2. The hair contacts the metal heat-conducting comb teeth 32, straightening the hair during the combing process. The heat insulation protective cover 31 prevents the metal heat-conducting comb teeth 32 from burning the scalp.

[0052] In this embodiment, the metal heat-conducting comb teeth 32 include a heat-conducting pillar 321 and several comb teeth 322. The cross-section of the comb teeth 322 is fan-shaped, so that the accessory head has a fan-shaped cross-section corresponding to the straightening area B, forming a large-area fan-shaped hair straightening heating area. The large-area fan-shaped hair straightening heating area heats the hair during combing to achieve a straightening and styling effect. The multiple comb teeth 322 are distributed laterally at intervals along the height of the heat-conducting pillar 321. Two adjacent comb teeth... There is a heating groove 3221 between the teeth, which is used to receive and heat the hair between them. The high temperature heat-conducting arc surface 3212 is formed on the bottom surface of the heating groove 3221. After the hair enters the heating groove 3221, the hair slides along the high temperature heat-conducting arc surface 3212. The hair is quickly heated and softened by high temperature in the heating groove 3221 and straightened. Multiple comb teeth 322 and heat-conducting pillars 321 are integrally formed. The integrally formed multiple comb teeth 322 and heat-conducting pillars 321 have the advantage of convenient installation.

[0053] In this first embodiment, the heat-conducting column 321 is provided with a heating mounting groove 3211. A pair of heat-conducting sheets 34 clamp the heating component 33 and place it in the heating mounting groove 3211. That is, the heat-conducting sheets 34 are in close contact with the inner wall of the heating mounting groove 3211, and the heating component 33 is located between the pair of heating components 33. The heating component 33 generates heat, which is then uniformly heated by the heat-conducting sheets 34. The metal heat-conducting comb teeth 32 can be heated so that the user can heat the hair when combing it to achieve a straightening and styling effect.

[0054] Furthermore, a high-temperature heat-conducting arc surface 3212 is provided between the heat-conducting pillar 321 and the comb teeth 322, and the comb teeth 322 are evenly distributed on the high-temperature heat-conducting arc surface 3212 along the longitudinal direction of the accessory head. When the straightening comb assembly 3 is fixedly installed on one side of the curling section 1, the high-temperature heat-conducting arc surface 3212 and the hot air heat-conducting arc surface 124 of the curling area A can together form a cylindrical surface, such as... Figure 10 This facilitates the flow of hot air around the curling section 1, improving the uniformity of heat distribution, and also allows for the hair to be wrapped around the curling section for styling.

[0055] Specifically, the curling zone A heats the hair by installing a heating resistance wire inside the product's internal flow channel to heat the flowing fluid and guide it to the curling zone A to heat the hair. At this time, the heat in the curling zone A is relatively uniform, with a temperature of about 110 to 140°C. The hair wrapped in the curling zone A needs to be continuously heated for a relatively long time (e.g., 8 to 30 seconds). The straightening zone B generates heat by directly embedding a high-power energized heating element inside the accessory head, and then directly conducts the heat to the hair through the metal heat-conducting comb teeth 32. At this time, the heating temperature in the straightening zone B is higher, generally around 180 to 230°C, which can achieve rapid heating, softening and straightening of the hair in a short time (generally within 2 to 5 seconds).

[0056] In this embodiment, the shape of the heat-insulating protective cover 31 matches the shape of the metal heat-conducting comb teeth 32. The heat-insulating protective cover 31 includes multiple integrally formed heat-insulating comb tooth sleeves 313. The cross-section of the heat-insulating comb tooth sleeves 313 is fan-shaped, and an inlet 3131 communicating with the receiving cavity 312 is provided between adjacent heat-insulating comb tooth sleeves 313. Each heat-insulating comb tooth sleeve 313 has an arc-shaped top surface 3132 on its outward-facing end face. The arc-shaped top surface 3132 is conducive to curling hair in a full circle. Rounded pointed teeth 311 are provided at both ends of the arc-shaped top surface 3132, which facilitates the entry of hair into the inlet 3131 and protects the scalp when combing hair.

[0057] The number of comb teeth 322 and heat-insulating comb sleeves 313 are the same. When the metal heat-conducting comb teeth 32 are set in the receiving cavity 312, the comb teeth 322 and the heat-insulating comb sleeves 313 are aligned. The inlet 3131 corresponds to and is connected to the heating groove 3221.

[0058] In this first embodiment, the curling section 1 includes a main support 11, a metal heat storage shell 12, and several sets of elastic comb teeth 14. The metal heat storage shell 12 covers the outer wall of the main support 11. A support platform 15 is provided on one side of the main support 11. After the straight hair comb assembly 3 is slidably installed on one side of the curling section 1, the heat-insulating gripper 13 is provided on the top of the curling section 1 and the straight hair comb assembly 3, and the curling section 1 and the straight hair comb assembly 3 are fixedly connected by the heat-insulating gripper 13. The elastic comb teeth 14 are implanted into the outer wall of the main support 11 through the first hair implantation hole 1132 provided on the main support 11. The elastic comb teeth 14 pass through the second hair implantation hole 123 provided on the metal heat storage shell 12 and are exposed on the surface of the metal heat storage shell 12. The hot air heat conduction arc surface 124 is formed on the outer surface of the metal heat storage shell 12. The elastic comb teeth 14 are elastic, bendable and deformable, and can be composed of several elastic bristles forming a hair tuft. They can comb hair and hold and grip hair.

[0059] Furthermore, the main support 11 includes a support mounting head 111, an annular support 112, several longitudinal beams 113, and several transverse beams 114. The longitudinal beams 113 are arranged in a ring along the annular support 112. The other end of the longitudinal beams 113 is connected to the support mounting head 111. The support mounting head 111 is connected to the annular support 112 through the longitudinal beams 113, so that a second ventilation chamber 16 for fluid flow is enclosed inside the main support 11. The annular support 112 is provided with a curling section air inlet 24 that communicates with the second ventilation chamber 16. Each adjacent longitudinal beam 113 is connected by several transverse beams 114. A first air outlet 17 for fluid flow is enclosed between the longitudinal beams 113 and the transverse beams 114. The first air outlet 17 communicates with the second ventilation chamber 16.

[0060] In this embodiment, the metal heat storage shell 12 covers the outer wall of the main support 11 and forms the hot air heat conduction arc surface 124 of the curled area A. Furthermore, a rotation stop block 1131 is provided on the longitudinal beam 113. The rotation stop block 1131 is located close to the annular support 112. The bottom of the metal heat storage shell 12 is provided with a rotation stop opening 121. When the metal heat storage shell 12 is placed on the main support 11, the rotation stop block 1131 is embedded in the rotation stop opening 121 to prevent the metal heat storage shell 12 from sliding relative to the main support 11, so that the metal heat storage shell 12 is tightly fitted on the outer wall of the main support 11 and rotates synchronously with the main support 11.

[0061] The outer wall of the metal heat storage shell 12 is provided with several racetrack-shaped air outlets 122 corresponding to the positions of the first air outlet 17. The shape of the racetrack-shaped air outlets 122 is smaller than that of the first air outlet 17. The fluid in the second ventilation chamber 16 flows from the first air outlet 17 to the metal heat storage shell 12. After the fluid heats the metal heat storage shell 12, it flows to the outside through the racetrack-shaped air outlets 122. The metal heat storage shell 12 is preferably made of aluminum or aluminum alloy, which has good thermal conductivity and heat storage properties. The metal heat storage shell 12 can better conduct the heat of the flowing hot air to the hair, thereby achieving the heating, softening and styling of the hair.

[0062] Furthermore, the outer wall of the longitudinal beam 113 is provided with a plurality of first hair implantation holes 1132, and the elastic comb teeth 14 are disposed in the first hair implantation holes 1132. The outer wall of the metal heat storage shell 12 is provided with a plurality of second hair implantation holes 123, the second hair implantation holes 123 being positioned corresponding to the first hair implantation holes 1132, and the elastic comb teeth 14 being exposed on the surface of the curling section 1 through the second hair implantation holes 123.

[0063] In this first embodiment, the connector 2 includes a mounting part 21 and a mounting post 22. The mounting part 21 is provided with a ventilation groove 211, which runs through the upper and lower surfaces of the mounting part 21. The mounting post 22 is disposed in the ventilation groove 211. The outer wall of the mounting post 22 is provided with several connecting ribs 23. The mounting post 22 is connected to the inner wall of the ventilation groove 211 through the connecting ribs 23. Each connecting rib 23 encloses several air inlets 24 for the curling part between the mounting post 22 and the inner wall of the ventilation groove 211. The curling part 1 is sleeved on the mounting post 22. The fluid provided by the handle 4 enters the curling part 1 through the air inlets 24.

[0064] In this first embodiment, the ventilation slot 211 has an installation block 212 on its wall surface, and the handle 4 has an installation interface 46 with a slot 461 that matches the installation block 212. The installation block 212 and the slot 461 are connected to each other so that the connector 2 is installed on the handle 4.

[0065] In this embodiment, the handle 4 has several air inlets 423 at its air inlet end and an air outlet 422 at its air outlet end. The handle 4 includes a shell 41, an inner shell 42, a control circuit board 43, a fan 44, and a heating element 45. The shell 41 covers the inner shell 42. The inner shell 42 has a first ventilation chamber 421 that communicates with the air inlets 423 and the air outlet 422. The control circuit board 43, the fan 44, and the heating element 45 are arranged sequentially from bottom to top in the first ventilation chamber 421. An installation interface 46 is fitted at the air outlet 422. The fan 44 and the heating element 45 are electrically connected to the control circuit board 43. In this embodiment, the control circuit board 43 drives the fan 44 to provide fluid flow to the curling section 1, and simultaneously drives the heating element 45 to provide heat to the passing fluid.

[0066] In this first embodiment, the handle 4 further includes a second power supply terminal 47, which is connected to the control circuit board 43 via a conductive lead. The second power supply terminal 47 is located at the air outlet 422 of the handle. The bottom of the mounting post 22 of the connector 2 is provided with a terminal groove 221, and the first power receiving terminal 18 is located in the terminal groove 221. When the curling part 1 is installed on the handle 4, the second power supply terminal 47 is inserted into the first power receiving terminal 18 for electrical connection.

[0067] This utility model relates to a tool for straightening and curling hair with hot air. By incorporating a straightening comb assembly 3 on the curling section 1, users can flexibly straighten or curl their hair, achieving a wider range of hairstyle designs. The straightening comb assembly 3 cleverly incorporates inner metal heat-conducting comb teeth and an outer heat-insulating comb tooth sleeve, forming a composite structure that efficiently conducts heat while preventing burns. The metal heat-conducting comb teeth 32 have a fan-shaped cross-section, increasing the area of ​​heat that can be applied to straighten the hair, allowing the heat to be more effectively distributed.

[0068] Example 2:

[0069] Combination Figure 17 As shown, the difference between this embodiment 2 and embodiment 1 is that the straightening comb assembly 3 is a single-tooth mode, and the cross-section of each comb tooth 322 is in the shape of a single-tooth gear. Furthermore, the cross-section of each comb tooth 322 is in the shape of a T-shaped single-tooth gear, and the shape of the corresponding heat-insulating comb sleeve 313 is matched to the shape of the comb tooth 322.

[0070] Example 3:

[0071] Combination Figure 18As shown, the difference between this embodiment three and embodiment two is that the straightening comb assembly 3 is a double-tooth mode, and the cross-section of each comb tooth 322 is a U-shaped double-tooth gear shape, and the shape of the corresponding heat-insulating comb sleeve 313 matches the shape of the comb tooth 322.

[0072] In this third embodiment, when the hair is combed into the straightening comb assembly 3, the straightening comb assembly 3 heats the hair sequentially through the two protruding teeth of the metal heat-conducting comb teeth 32. The segmented heating satisfies the need for hair layering and enhances the three-dimensional effect.

[0073] Example 4:

[0074] Combination Figure 19 As shown, the difference between Embodiment 4 and Embodiment 3 is that the straightening comb assembly 3 is a three-tooth design. The cross-section of each comb tooth 322 is an E-shaped three-tooth gear, and the shape of the corresponding heat-insulating comb sleeve 313 matches the shape of the comb tooth 322. In Embodiment 4, there are three metal heat-conducting comb teeth 32, which facilitates the combing of hair into the straightening comb assembly 3 and the curling of hair. After the hair is combed into the straightening comb assembly 3, the three protruding teeth of the metal heat-conducting comb teeth 32 heat the hair in three sections in sequence. The segmented heating function further satisfies the layering of the hair and enhances the three-dimensionality.

[0075] Example 5:

[0076] The difference between this fifth embodiment and the first embodiment is the method of power connection. In the fifth embodiment, the connector 2 is provided with a first power-connecting pin 19, and the handle 4 is provided with a first power-transmitting pin 48 that is electrically connected to the control circuit board 43. When the connector 2 is installed on the handle 4, the first power-connecting pin 19 and the first power-transmitting pin 48 are mated and cooperated to realize the electrical connection between the handle 4 and the connector 2.

[0077] Specifically, the connector 2 is provided with a first power-connecting mounting hole 25, and the first power-connecting pin 19 is inserted through the first power-connecting mounting hole 25 and exposed on the surface of the connector 2.
