Description

Technical Field

[0001] The present invention relates to the technical field of hairdressing equipment, in particular to an automatic hair curler. Background Art

[0002] In the patent number CN201620251289.9, an improved curling iron is proposed, including a hand-held handle; a curling assembly mounted on the hand-held handle, the curling assembly including a heating rod, a toggle and a shell, the shell is arranged around the outside of the heating rod and an opening is formed at the top, the toggle is installed between the shell and the heating rod, the toggle and the heating rod are in clearance and can rotate around the central axis of the heating rod; a driving device for driving the toggle to rotate relative to the heating rod, when in use, the hair is put into the gap, the driving device drives the toggle to drive the hair to rotate so as to wrap the hair around the outside of the heating rod and curl the hair. However, in order to achieve the purpose of making the hair wrapped around the heating rod not easy to fall off when people curl their hair, the gap between the toggle and the heating rod is small, so it is not convenient for the user to put the hair between the toggle and the heating rod through the opening of the shell for curling, and when the hair is taken out after the perm, it is easy to pull the hair, destroying the newly made style. Summary of the invention

[0003] Purpose of the present invention: In order to overcome the defects of the prior art, the present invention provides an automatic hair curler, which is convenient for people to put hair into the hair curler for curling and to easily take out hair after curling.

[0005] By adopting the above technical scheme, when the curling iron of the present invention is in use, the upper part of the hair guide plate can be driven to open outwards by the opening and closing device, so that the hair can be put into the heating chamber from the opening. Then, the upper part of the hair guide plate can be driven inwards by the opening and closing device to clamp the hair. At this time, the driving device drives the toggle member to drive the hair to rotate so as to wrap the hair around the outside of the heating rod and curl the hair, thereby achieving the purpose of making it easy for people to put the hair into the curling iron for curling and to take it out easily and conveniently after curling.

[0006] The present invention is further configured as follows: the hand-held handle includes a hand-held portion and a mounting portion, the mounting portion is located between the toggle member and the hair guide plate, the hair guide plate is rotatably arranged on the mounting portion via the mounting shaft, the opening and closing device includes an operating member, the operating member can drive the lower portion of the hair guide plate to be expanded outward, so that the hair guide plate rotates around the mounting shaft, thereby realizing the inward retraction of the upper portion of the hair guide plate, and the opening and closing device also includes a reset member for expanding the upper portion of the hair guide plate outward.

[0035] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that it can be implemented by technicians in this field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0036] like Figure 1-11As shown, an automatic hair curler of the present invention comprises a hand-held handle 1, a hair curling assembly 2 mounted on the hand-held handle 1, and a hair guide plate 23, wherein the hair curling assembly 2 comprises a heating rod 21 and a toggle member 22, the hair guide plate 23 is arranged around the outside of the heating rod 21 to form a heating chamber 3 and has an opening 4 formed at the top, a hair guide channel 5 for hair to pass through is also arranged on the side wall of the hair guide plate 23, the toggle member 22 is installed in the heating chamber 3 and can rotate around the heating rod 21, and a driving device 6 for driving the toggle member 22 to rotate is also installed on the hand-held handle 1, the hair guide plate 23 is surrounded by at least two separately arranged hair guide plates 7, the hair guide plates 7 can be movably mounted on the hand-held handle 1, and further comprises an opening and closing device 8, the opening and closing device 8 can drive the upper part of the hair guide plate 7 to open outward and close inward; the hand-held handle 1 comprises a hand-held portion 11 and a mounting portion 12, the mounting portion 12 is located between the toggle member 22 and the guide plate Between the hair plates 23, the hair guide plate 7 is rotatably arranged on the mounting portion 12 via the mounting shaft 9. The opening and closing device 8 includes an operating member 81. The operating member 81 can drive the lower portion of the hair guide plate 7 to expand outward, so that the hair guide plate 7 rotates around the mounting shaft 9 to achieve the inward retraction of the upper portion of the hair guide plate 7. The opening and closing device 8 also includes a reset member 82 for expanding the upper portion of the hair guide plate 7 outward; the reset member 82 is a first torsion spring, which is mounted on the mounting portion 12, and the end of the first torsion spring 82 contacts the upper inner wall of the hair guide plate 7. The operating member 81 is a button, which is mounted on the handheld portion 11. A second torsion spring 10 is mounted on the button 81, and one end of the second torsion spring 10 contacts the button 81, and the other end extends out of the button 81. When the button 81 is pressed, the other end of the second torsion spring 10 can contact the lower inner wall of the hair guide plate 7 to drive it to expand outward. When the hair curler of the present invention is in a natural state (not in use), the first torsion spring 82 stretches the upper portion of the hair guide plate 7 outward, and the lower portion of the hair guide plate 7 is retracted inward. At this time, the upper portion of the heating chamber 3 is expanded, which is convenient for putting hair in and taking out hair. When curling hair, the button 81 is pressed, and the button 81 can abut against one end of the second torsion spring 10 to drive it to press inward, so that the other end of the second torsion spring 10 tilts outward to abut against the inner wall of the lower portion of the hair guide plate 7 to drive it to stretch outward, so that the hair guide plate 7 rotates around the mounting axis, and the upper portion of the hair guide plate 7 is retracted inward, and the upper portion of the heating chamber 3 is retracted, so as to clamp the hair.
