Description

Technical Field

[0001] The utility model relates to the technical field of hairdressing products, in particular to a curling rod. Background Art

[0002] A curling iron is a hairdressing DIY tool, and with the development of the times, curling irons have come in various forms. Automatic curling irons are widely loved by consumers because of their ease of use and simple operation.

[0003] For example, the patent document with publication number CN115067656B records an automatic curling iron, in which two oppositely arranged U-shaped guide grooves are opened on the side wall of the limiting device located at the end of the heating device. During the curling process, a strand of hair is passed through the two U-shaped guide grooves in succession, the hair is limited and guided downward to the outside of the heating device, and then guided by the hair curler arranged around the outside of the heating element and automatically driven to be rolled onto the surface of the heating device.

[0004] However, the automatic curling iron of the above structure has some problems when in use. Due to the small size of the curling iron, the depth of the two U-shaped guide grooves oppositely arranged on the side wall of the limiting device is relatively shallow, and the guiding angle varies greatly. The limiting and downward guiding effects on the hair are limited. When the hair curler is rotated, the hair is not easy to be quickly wound around the heating device, and the hair curling effect is not good when the hair is automatically wound. Utility Model Content

[0005] In order to solve the problems existing in the above-mentioned background technology, the utility model provides a curling iron, which is convenient for putting hair in, better orients the hair and guides it downward, makes it easier and faster to wrap the hair around the heating element later, and the hair can be removed from the heating element more smoothly after heating and styling.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] The utility model provides a hair curling rod, comprising a handle, a guide, a heating element and a hair winding assembly;

[0008] A heating element is provided at one end of the handle, a hair winding assembly is rotatably provided on the outer side of the heating element, and a guide element is provided on the end of the heating element away from the handle;

[0009] The guide member is a structure with a hollow interior and an open top. Two relatively vertically arranged hair guide grooves are provided on the side of the guide member. The hair guide grooves extend upward to the open end of the guide member. The bottom of the guide member is recessed downward to form an inclined groove connected to its internal space. The bottom outlet end of the inclined groove is connected to one of the hair guide grooves.

[0010] Further, the inclined angle of the inclined groove is 1-89 degrees. Preferably, the inclined angle of the inclined groove is 20-60 degrees. The inclined groove in this inclined angle range has a suitable guide depth and guide inclination, and the directional limiting effect is better.

[0011] Furthermore, the heating element is a columnar structure with a hollow interior and openings at both ends.

[0012] Existing heating elements usually have through holes, air intake holes, slots or gaps. When the hair is automatically wrapped around the surface of the heating element, the hair can easily enter the through holes, air intake holes, slots or gaps and get tangled around the heating element. It is difficult to remove the hair from the heating element when using it, and the hair may be pulled out when using it. The heating element of the present application does not have through holes, slots or gaps, and by providing an inclined slot on the guide, the hair can be automatically and quickly wrapped around the heating element, and the hair will not get tangled or knotted. After shaping, the hair can be removed from the heating part smoothly and quickly; and the effective heating area on the surface of the heating element becomes larger, which is more conducive to the heating and shaping of the hair.

[0013] Furthermore, a notch is provided on the side of the heating element, and the notch extends upward to the opening end of the heating element. The inclined groove at the bottom of the guide element extends into the interior of the heating element, and the bottom outlet end of the inclined groove is arranged to match the notch.

[0014] When in use, the lower middle part of the heating element cooperates with the hair winding assembly to clamp and limit the hair and heat and shape it. The outer side of the top of the heating element is less effective in curling and shaping the hair. In the present application, the inclined groove at the bottom of the guide is installed inside the heating element, and the inclined groove is exposed by the notch on the outer side of the top of the heating element, so as to reasonably utilize the space outside the top of the heating element, reduce the volume of the curling rod, and do not affect the effective use position of the heating element.

[0015] Furthermore, a heat insulating sheet is provided between the heating element and the guide element, and a downwardly recessed positioning groove is formed on the heat insulating sheet and matches the inclined groove structure at the bottom of the guide element. The top of the heat insulating sheet is fitted and installed with the bottom of the guide element, and the bottom of the heat insulating sheet is provided with a downwardly extending engaging end, and the engaging end is embedded and installed in the interior of the heating element through the opening end of the heating element, and the bottom of the heat insulating sheet is fitted and installed with the opening end of the heating element.

[0016] By setting the structure of the heat insulation sheet to match the shape structure of the bottom of the guide member, an effective heat insulation effect is achieved to isolate the guide member from the heating member, and the bottom of the heat insulation sheet is embedded in the interior of the heating member through the engaging end, which is convenient for positioning and installation, and the overall volume is small after installation.

[0017] Furthermore, a plurality of fastening holes are provided at corresponding locations of the opening ends of the guide member, the heat insulating sheet and the heater, and the guide member, the heat insulating sheet and the heater are fastened and connected by fasteners passing through the corresponding fastening holes in sequence.

[0018] First, the inclined groove at the bottom of the guide piece is inserted into the positioning groove on the thermal insulation sheet to achieve pre-positioning installation of the two. Then, the engaging end at the bottom of the thermal insulation sheet is embedded and installed into the interior of the heater through the open end, and the outlet end at the bottom of the inclined groove is aligned with the notch on the heater to achieve pre-positioning installation of the guide piece, the thermal insulation sheet and the heater. Finally, fasteners are passed through the fastening holes at the open ends of the guide piece, the thermal insulation sheet and the heater in turn to firmly install the three into a whole. The entire installation process is convenient and quick to operate, and the appearance is simple and beautiful.

[0019] Furthermore, the hair winding assembly includes a base and a plurality of clamps, the base is provided with a plurality of clamps, the plurality of clamps are arranged around the outside of the heating element, the inner wall of the clamp is formed with a limiting ridge for abutting the hair against the outside of the heating element, the top of the limiting ridge is located at a position not higher than the bottom of the notch, and the bottom of the limiting ridge extends downward to be connected to the top of the base.

[0020] When in use, the clamping jaws are rotated, and the limiting ridges on the inner side of the clamping jaws cooperate with the outer side of the heating element to limit the hair, so that the hair is rolled inward or outward in sequence and rolled evenly on the outer side of the heating element. The limiting ridges can also make the hair abut against the outer side of the heating element, so that the contact area between the hair and the outer side of the heating element becomes larger, and the hair heating and rolling effect is better. In addition, the position of the limiting ridges is reasonably set, and a relatively large gap can be formed between the upper inner side of the clamping jaws (where the limiting ridges are not set) and the outer side of the heating element, which is convenient for guiding the hair to enter when the clamping jaws are rotated, and it is also convenient for taking the hair out of the outer side of the heating element after heating and styling. The bottom of the limiting ridges is connected to the top of the base, and there will be no gap at the bottom of the inner side of the clamping jaws, so the hair will not be hooked when entering the gap.

[0021] Furthermore, an arc-shaped transition connection portion is formed between the top of the limiting convex ridge and the inner side wall of the clamping jaw.

[0022] With the above-mentioned structural arrangement, the hair can be more conveniently and quickly guided between the clamping jaws and the heating element when the clamping jaws are rotated, and the hair after heating and styling can be quickly taken out from the outside of the heating element.

[0023] Furthermore, the distance between two adjacent clamping jaws from the bottom to the top of the limiting ridge gradually decreases, and the distance between the upper parts of two adjacent clamping jaws where no limiting ridge is set gradually increases from bottom to top.

[0024] The distance between the middle and lower parts of two adjacent clamping jaws gradually decreases from bottom to top, and when the hair enters this place from the hair guide groove and the inclined groove, it can limit the hair at this place, and when the clamping jaws are rotated subsequently, it can better drive the hair to be rolled around the outside of the heating element. The distance between the upper parts of two adjacent clamping jaws gradually increases from bottom to top, which can better and faster guide the hair to enter between the clamping jaws and the heating element.

[0025] Compared with the prior art, the utility model has the following beneficial effects:

[0026] In the utility model, an inclined groove connected to the internal space of the guide member is formed by recessing downward at the bottom of the guide member, and the bottom outlet end of the inclined groove is connected to one of the hair guide grooves, so that the hair is better placed. When in use, the hair is oriented and guided downward to the heating member through the action of the two hair guide grooves and the inclined groove on the guide member, and the directional limiting effect is good. The hair winding component is rotated to more easily and quickly wind the hair around the heating member, and the hair can be removed from the heating member more smoothly after heating and shaping.

[0040] like Figure 1 and Figure 2 As shown, a curling iron comprises a handle 1, a guide 2, a heating element 4 and a hair winding assembly 5;

[0041] A heating element 4 is provided at one end of the handle 1, a hair winding assembly 5 is rotatably provided outside the heating element 4, and a guide element 2 is provided at the end of the heating element 4 away from the handle 1;

[0042] The guide member 2 is a structure with a hollow interior and an open top. Two relatively vertically arranged hair guide grooves 201 are provided on the side of the guide member 2. The hair guide groove 201 extends upward to the open end of the guide member 2. The bottom of the guide member 2 is recessed downward to form an inclined groove 202 connected to its internal space. The bottom outlet end of the inclined groove 202 is connected to one of the hair guide grooves 201.

[0043] When in use, the two hair guide grooves 201 and the inclined groove 202 on the guide member 2 facilitate the insertion of hair, and the hair can be oriented and guided downward to the heating member 4, with good directional limiting effect. By rotating the hair winding component 5, the hair can be more easily and quickly wound around the heating member 4, and the hair can be removed from the heating member 4 more smoothly after heating and styling.

[0044] The inclined angle of the inclined groove 202 is 1-89 degrees. Preferably, the inclined angle of the inclined groove 202 is 20-60 degrees. The inclined groove 202 in this inclined angle range has a suitable guide depth and guide inclination, and the directional limiting effect is better.

[0045] Among them, Figure 3 As shown, the heating element 4 is a columnar structure with a hollow interior and openings at both ends. The existing heating element 4 is usually provided with through air outlet holes, air suction holes, through slots or gaps. When the hair is automatically wrapped around the surface of the heating element 4, the hair can easily enter the through air outlet holes, air suction holes, through slots or gaps, and the hair is entangled on the heating element 4. When using, it is difficult to remove the hair from the heating element 4, and there will be problems of pulling the hair when using it. The heating element 4 of the present application does not have through holes, through slots or gaps, and by providing an inclined groove 202 on the guide 2, the hair can be automatically and quickly wrapped around the heating element 4, and the hair will not be entangled and knotted. After shaping, the hair can be smoothly and quickly removed from the heating part; and the effective heating area on the surface of the heating element 4 becomes larger, which can be more conducive to the heating and shaping of the hair.

[0046] Among them, a notch 401 is provided on the side of the heating element 4, and the notch 401 extends upward to the open end of the heating element 4. The inclined groove 202 at the bottom of the guide member 2 extends into the interior of the heating element 4, and the bottom outlet end of the inclined groove 202 is arranged to be matched with the notch 401. When in use, the hair is usually clamped and limited and heated and shaped by cooperating with the hair winding assembly 5 in the middle and lower part of the heating element 4. The outer side of the top of the heating element 4 is less effective in curling and shaping. In the present application, the inclined groove 202 at the bottom of the guide member 2 is installed inside the heating element 4, and the notch 401 on the outer side of the top of the heating element 4 exposes the inclined groove 202, so as to reasonably utilize the space outside the top of the heating element 4, reduce the volume of the curling rod, and do not affect the effective use position of the heating element 4.

[0047] Among them, a heat insulating sheet 3 is provided between the heating element 4 and the guide element 2, and a positioning groove 301 is formed on the heat insulating sheet 3, which is concave downward and matches the structure of the inclined groove 202 at the bottom of the guide element 2.

[0048] Among them, a plurality of fastening holes 6 are provided at the corresponding positions of the opening ends of the guide member 2, the heat insulating sheet 3 and the heating member 4. The fasteners pass through the corresponding fastening holes 6 in sequence to fasten the guide member 2, the heat insulating sheet 3 and the heating member 4. First, the inclined groove 202 at the bottom of the guide member 2 is inserted into the positioning groove 301 on the heat insulating sheet 3 in a directional manner to achieve the pre-positioning installation of the two. Then, the engaging end 302 at the bottom of the heat insulating sheet 3 is embedded and installed into the interior of the heating member 4 from the opening end, and the bottom outlet end of the inclined groove 202 corresponds to the notch 401 on the heating member 4 to achieve the pre-positioning installation of the guide member 2, the heat insulating sheet 3 and the heating member 4. Finally, the fasteners pass through the fastening holes 6 at the opening ends of the guide member 2, the heat insulating sheet 3 and the heating member 4 in sequence to firmly install the three to form a whole. The entire installation process is convenient and fast to operate, and the appearance is simple and beautiful.

[0049] Among them, Figure 4As shown, the hair winding component 5 includes a base 501 and a plurality of clamping claws 502.

A through hole is formed in the middle of the base 501 for the heating element 4 to pass through. A plurality of clamping claws 502 are arranged on the base 501. The plurality of clamping claws 502 are arranged around the outside of the heating element 4. The inner wall of the clamping claw 502 is formed with a limiting rib 503 for abutting the hair against the outside of the heating element 4. The top of the limiting rib 503 is located at a position not higher than the bottom of the notch 401, and the bottom of the limiting rib 503 extends downward to be connected to the top of the base 501. When in use, the clamping jaw 502 is rotated, and the limiting convex rib 503 located on the inner side of the clamping jaw 502 cooperates with the outer side of the heating element 4 to limit the hair, so that the hair is rolled inward or outward in sequence and rolled evenly on the outer side of the heating element 4. The limiting convex rib 503 can also make the hair abut against the outer side of the heating element 4, so that the contact area between the hair and the outer side of the heating element 4 becomes larger, and the hair heating and rolling effect is better. In addition, the position of the limiting convex rib 503 is reasonably set, and a relatively large gap can be formed between the upper inner side of the clamping jaw 502 (where the limiting convex rib 503 is not set) and the outer side of the heating element 4, which is convenient for guiding the hair to enter when the clamping jaw 502 is rotated, and it is also convenient for taking the hair out of the outer side of the heating element 4 after heating and styling. The bottom of the limiting convex rib 503 is connected to the top of the base 501, and there is no gap at the bottom of the inner side of the clamping jaw 502, so that the hair will not be hooked when entering the gap.

[0050] An arc-shaped transition connection portion 504 is formed between the top of the limiting convex ridge 503 and the inner wall of the clamping jaw 502. With the above-mentioned structural arrangement, when the clamping jaw 502 is rotated, the hair can be more conveniently and quickly guided into between the clamping jaw 502 and the heating element 4, and the hair after heating and styling can be quickly taken out from the outside of the heating element 4.

[0051] The distance between two adjacent clamping jaws 502 from the bottom to the top of the limiting convex rib 503 gradually decreases, and the distance between the upper parts of two adjacent clamping jaws 502 where the limiting convex rib 503 is not provided gradually increases from bottom to top. The distance between the middle and lower parts of two adjacent clamping jaws 502 gradually decreases from bottom to top, and when the hair enters the hair guide groove 201 and the inclined groove 202 to this place, it can play a limiting role on the hair at this place, and when the clamping jaws 502 are rotated subsequently, it can better drive the hair to be wound around the outside of the heating element 4. The distance between the upper parts of two adjacent clamping jaws 502 gradually increases from bottom to top, which can better and faster guide the hair to enter between the clamping jaws 502 and the heating element 4.
