Description

Technical Field

[0001] This utility model belongs to the field of hair styling product technology, and in particular relates to a hair curler. Background Technology

[0002] Curling irons are a common electrical appliance in the hairdressing industry and daily life. They typically consist of a handle and a curling iron. The curling iron has a heating element inside, which generates high temperatures and conducts the temperature to the surface of the curling iron, thus heating the hair to create curls.

[0003] Chinese patent document CN219515538U discloses a multifunctional electric hair curler structure, including a handle, a hair curler fixedly connected to the left end of the handle via a driver, several comb teeth fixedly connected to the outer surface of the hair curler, a first threaded hole opened at the left end of the hair curler, a protective mechanism threadedly connected to the left end of the hair curler via the first threaded hole, three locking strips fixedly connected to the left part of the outer surface of the handle, and three indicator lights fixedly installed on the upper left side of the outer surface of the handle, the three indicator lights being equidistantly distributed and not in contact with each other.

[0004] In the aforementioned patent document, a number of comb teeth are fixedly connected to the surface of the hair curler. When curling hair, the user wraps their hair around the hair curler, and the curl is achieved through the heat of the curler. The hair inside the curler is hotter than the hair outside, resulting in uneven heating and poor curl setting. Utility Model Content

[0005] The purpose of this invention is to provide a hair curler that solves the problem that when existing hair curlers heat and style hair, the temperature of the hair inside the heating structure of the curling iron is higher than that on the outside, resulting in poor curling effect.

[0006] To achieve the above objectives, this utility model provides a hair curler, including a handle and a curling part connected together. The curling part includes a heat-conducting tube coaxially arranged, a heating element disposed inside the heat-conducting tube, and multiple rows of heat-insulating comb teeth spaced apart around the heat-conducting tube. The heat-conducting tube is also provided with multiple heat-conducting protrusions alternating with the heat-insulating comb teeth in the circumferential direction. The multiple heat-conducting protrusions are spaced apart along the length direction of the heat-conducting tube, and the distance between the free end of the heat-insulating comb teeth and the axis of the heat-conducting tube is greater than the corresponding distance between the free ends of the heat-conducting protrusions.

[0007] Furthermore, the plurality of the heat-conducting protrusions are spirally distributed on the outer periphery of the heat-conducting pipe.

[0008] Furthermore, the heat-conducting protrusions extend radially along the outer surface of the heat-conducting pipe, the extension direction of a single heat-conducting protrusion is parallel to the cross-section of the heat-conducting pipe, and multiple rows of heat-conducting protrusions are arranged parallel to each other along the axial direction of the heat-conducting pipe.

[0009] Furthermore, the heat-conducting pipe is a metal pipe, and the heat-conducting protrusions are integrally formed on the outer surface of the heat-conducting pipe.

[0010] Furthermore, the curved extension length of the free end of the heat-conducting protrusion is greater than the curved length of the connecting end, and the distance between the free ends of adjacent heat-conducting protrusions along the circumferential direction of the heat-conducting pipe is equidistant from the distance between the connecting ends.

[0011] Furthermore, the free end of the heat-conducting protrusion is provided with a guide surface.

[0012] Furthermore, the heat-insulating comb includes an mounting strip and a plurality of axially arranged heat-insulating teeth. The heat-conducting pipe is provided with an inwardly recessed mounting groove. The mounting strip is embedded in the mounting groove. The spacing between axially adjacent heat-conducting protrusions is smaller than the spacing between axially adjacent heat-insulating teeth.

[0013] Furthermore, the top and bottom of the curling section are respectively provided with a protective sleeve and a heat insulation sleeve, and the other end of the heat insulation sleeve is connected to the handle; the protective cover and the heat insulation sleeve are respectively fitted on both ends of the heat-conducting pipe and have multiple anti-scalding protrusions and heat-insulating protrusions extending radially on their outer periphery, and the axial projection of the anti-scalding protrusions and heat-insulating protrusions overlaps with the corresponding heat-conducting protrusions.

[0014] Furthermore, the inner wall of the heat-conducting pipe extends inward with multiple positioning posts, and adjacent positioning posts and the inner wall of the heat-conducting pipe respectively form slots and positioning grooves. The slots and positioning grooves are adjacent and circumferentially arranged inside the heat-conducting pipe. The slots are used to install the heating element. The bottom of the protective sleeve extends downward with a snap-fit ​​part for snapping between adjacent positioning posts. The top of the heat insulation sleeve extends upward with a positioning element for positioning in the positioning groove.

[0015] Furthermore, the positioning post is provided with a through positioning hole, and an opening is provided on one side of the positioning hole; the snap-fit ​​part is provided with a snap-fit ​​block that snaps into the positioning hole; the heat insulation sleeve is provided with a connecting hole, and the connecting hole corresponds one-to-one with the positioning hole.

[0016] The hair curler provided in this embodiment of the present invention has at least the following technical effects:

[0017] Because the heating element is located inside the heat-conducting pipe of the curling section, and the outer surface of the heat-conducting pipe has alternating heat-insulating comb teeth and heat-conducting protrusions distributed circumferentially, when the user wraps their hair around the curling section, the heat-conducting protrusions work together with the heat-insulating comb teeth to comb and hold the hair in place, preventing it from loosening during wrapping and heating styling. The heat-conducting protrusions increase the heat contact area with the hair. When the heating element is energized, heat is transferred to the heat-conducting pipe and heat-conducting protrusions. The heat-conducting protrusions work with the heat-conducting pipe to heat and set the hair on the inside and sides, ensuring that the hair on both sides is heated evenly, ensuring the styling effect of the curl, improving the quality of the curl, and saving curling time. In addition, the distance between the free end of the heat-insulating comb teeth and the axis of the heat-conducting pipe is greater than the corresponding distance between the free ends of the heat-conducting protrusions. The longer heat-insulating comb teeth can prevent the heat-conducting protrusions from contacting the skin, avoiding burns from the heat of the heat-conducting protrusions; and when placed horizontally, the heat-insulating comb teeth can support and protect the heat-conducting protrusions.

Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0034] In one embodiment of the hair curler of this utility model, please refer to Figures 1 to 9 A hair curler includes a handle 200 and a curling section 100 connected to each other. The curling section 100 includes a coaxially arranged heat-conducting pipe 110, a heating element 120 disposed inside the heat-conducting pipe 110, and multiple rows of heat-insulating comb teeth 130 spaced apart around the heat-conducting pipe 110. The heat-conducting pipe 110 is also provided with multiple heat-conducting protrusions 140 alternating with the heat-insulating comb teeth. The multiple heat-conducting protrusions 140 are spaced apart along the length of the heat-conducting pipe 110, and the distance between the free end of the heat-insulating comb teeth 130 and the axis of the heat-conducting pipe 110 is greater than the corresponding distance between the free ends of the heat-conducting protrusions 140. Specifically, the heat-conducting pipe 110 of the curling section contains a heating element 120, and the outer surface of the heat-conducting pipe 110 is circumferentially provided with alternating heat-insulating comb teeth 130 and heat-conducting protrusions 140. When the user wraps their hair around the curling section 100, the heat-conducting protrusions 140 work together with the heat-insulating comb teeth 130 to comb the hair and clamp and fix it, making it less likely to loosen during wrapping and heating styling. The heat-conducting protrusions 140 increase the heat-conducting contact area with the hair. When the heating element 120 is powered on, heat is transferred to the heat-conducting pipe 110 and the heat-conducting protrusions 140. The heat-conducting protrusions 140 work with the heat-conducting pipe 110 to heat and set the hair on the inner and outer sides, so that the hair on the inner and outer sides can be heated evenly, ensuring the styling effect of the curl, improving the quality of the curl, and saving curling operation time. In addition, the distance between the free end of the heat-insulating comb 130 and the axis of the heat-conducting pipe 110 is greater than the corresponding distance between the free ends of the heat-conducting protrusions 140. The longer heat-insulating comb 130 can prevent the heat-conducting protrusions 140 from contacting the skin and avoid the heat from the heat-conducting protrusions 140 from burning the skin. When placed horizontally, the heat-insulating comb 130 can support and protect the heat-conducting protrusions 140.

[0035] For further details, please refer to... Figure 3 Multiple heat-conducting protrusions 140 are spirally distributed around the outer periphery of the heat-conducting pipe 110. Specifically, each heat-conducting protrusion 140 is set at a certain angle to the cross-section of the heat-conducting pipe 110, which further increases the contact area between the heat-conducting protrusion 140 and the hair, and enhances the hair fixing and curl styling effect.

[0036] For further details, please refer to... Figure 2The heat-conducting protrusions 140 extend radially along the outer surface of the heat-conducting pipe 110. The extension direction of a single heat-conducting protrusion 140 is parallel to the cross-section of the heat-conducting pipe 110, and multiple rows of heat-conducting protrusions 140 are arranged parallel to each other along the axial direction of the heat-conducting pipe 110. Specifically, the axially parallel arrangement of the heat-conducting protrusions 140 facilitates the formation of neat and regular curls, forming different curl styles compared to the spiral distribution of the heat-conducting protrusions 140.

[0037] For further details, please refer to... Figure 4 The heat pipe 110 is a metal tube, and the heat-conducting protrusions 140 are integrally formed on the outer surface of the heat pipe 110. Specifically, the heat pipe 110 and the heat-conducting protrusions 140 are made of aluminum and are integrally formed. The thermal conductivity of aluminum ensures that the heat from the heating element 120 can be quickly transferred to the heat pipe 110 and the heat-conducting protrusions 140, making their heating times similar and enhancing the structural strength of the connection, thus extending their service life.

[0038] For further details, please refer to... Figure 4 The curved extension length of the free end of the heat-conducting protrusion 140 is greater than the curved extension length of the connecting end, and the distance between the free ends of adjacent heat-conducting protrusions 140 and the distance between the connecting ends are equidistant along the circumferential direction of the heat-conducting pipe 110. Specifically, because the curved extension length of the free end of the heat-conducting protrusion 140 is longer, the contact area between the outer hair and the heat-conducting protrusion 140 is increased, and the equidistant distribution of the free ends and connecting ends of adjacent heat-conducting protrusions 140 further improves the uniformity of heat distribution on the hair and ensures the curling effect.

[0039] For further details, please refer to... Figure 2 and Figure 3 The free end of the heat-conducting protrusion 140 is provided with a guide surface 141. Specifically, the guide surface 141 guides the hair into the groove formed by the axially adjacent heat-conducting protrusions 140.

[0040] Preferably, the free end of the heat-conducting protrusion 140 is a pointed tip, and the two sides of the free end are inclined guide surfaces 141, forming an inverted V shape. Specifically, guide surfaces 141 are provided on both sides of the top of the heat-conducting protrusion 140 to reduce friction and increase the speed at which hair wraps around the curling section 100.

[0041] For further details, please refer to... Figure 5 The heat-insulating comb 130 includes a mounting strip 131 and a plurality of axially arranged heat-insulating teeth 132. The heat-conducting pipe 110 is provided with an inwardly recessed mounting groove 111, in which the mounting strip 131 is embedded. The spacing between axially adjacent heat-conducting protrusions 140 is smaller than the spacing between axially adjacent heat-insulating teeth 132. Specifically, the number of axially arranged heat-conducting protrusions 140 is greater than the number of heat-insulating teeth 132, which enhances the structural strength, further increases the contact area between the heat-conducting protrusions 140 and the hair, and enhances the positioning effect on the hair in conjunction with the adjacent heat-insulating teeth 132, thereby improving the heating and styling efficiency and saving operation time.

[0042] Preferably, the two ends of the curved surface of the heat-conducting protrusion 140 connected to the heat-conducting pipe 110 extend to the edge of the mounting groove 111 of the heat-conducting pipe 110.

[0043] For further details, please refer to... Figure 1 , Figure 6 and Figure 7 The top and bottom of the curling section 100 are respectively provided with a protective cover 150 and a heat insulation cover 160, and the other end of the heat insulation cover 160 is connected to the handle 200. The protective cover 150 and the heat insulation cover 160 are respectively fitted over both ends of the heat-conducting tube 110 and have multiple anti-scalding protrusions 151 and heat insulation protrusions 161 extending radially on their outer periphery. The axial projections of the anti-scalding protrusions 151 and heat insulation protrusions 161 overlap with the corresponding heat-conducting protrusions 140. Specifically, the anti-scalding cover 150 and the heat insulation cover 160 protect the skin axially, and the anti-scalding protrusions 151 and heat insulation protrusions 161 protect the skin radially, preventing the heat-conducting tube 110 and heat-conducting protrusions 140 from burning the user during the curling process.

[0044] For further details, please refer to... Figures 6 to 9 The inner wall of the heat pipe 110 extends inward with multiple positioning posts 112. Adjacent positioning posts 112 and the inner wall of the heat pipe 110 respectively form slots 114 and positioning grooves 115. The slots 114 and positioning grooves 115 are adjacent and circumferentially arranged inside the heat pipe 110. The slots 114 are used to install the heating element 120. The bottom of the protective sleeve 150 extends downward with a snap-fit ​​part 152 for snapping between adjacent positioning posts 112. The top of the heat insulation sleeve 160 extends upward with a positioning element 162 for positioning in the positioning groove 115. Specifically, the slots 114 install the heating element 120, the heat insulation sleeve 160 is fitted onto the bottom end of the heat pipe 110 and connected to the positioning groove 115 via the positioning element 162 to achieve a fixed connection with the heat pipe 110, and the protective sleeve 150 is fitted onto the top end of the heat pipe 110 and fixedly connected to the heat pipe 110 via the snap-fit ​​part 152. The assembly operation is simple.

[0045] Preferably, please refer to Figure 8 It also includes a bent spring 121, one side of which abuts against the heating element 120, and the other side extends outward to abut against the sidewalls of the two positioning posts 112 of the slot 114. Specifically, the bent spring 121 ensures that the heating element 120 is in close contact with the inner wall of the heat pipe 110, thereby improving the heat conduction efficiency; and is adaptable to fixing heating elements 120 of different sizes.

[0046] For further details, please refer to... Figures 6 to 9The positioning post 112 has a through positioning hole 113, and an opening is provided on one side of the positioning hole 113. The snap-fit ​​part 152 has a snap-fit ​​block 153 for snapping into the positioning hole 113. The heat insulation sleeve 160 has a connecting hole 163, which corresponds one-to-one with the positioning hole 113. Specifically, the protective sleeve 150 is snapped into the positioning hole 113 by the snap-fit ​​block 153, and the heat insulation sleeve 160 is locked with the connecting hole 163 and the positioning hole 113 by a locking member to improve the stability of the connection.
