Description

Technical Field

[0001] The invention belongs to the technical field of hair straighteners, in particular to an air guide structure of a hair straightener. Background Art

[0002] A hair straightener is a commonly used device for straightening and straightening hair. Existing hair straighteners generally include two rotatably connected hairpins, with a heating body provided on opposite sides of the hairpins. When in use, the hair is clamped between the two hairpins and the heat emitted by the heating body drags the hair to achieve straightening or straightening of the hair. However, the temperature of the heating body of such existing hairpins is often high, which can easily damage the hair during use, causing problems such as dry, yellow, and dehydrated hair. To solve this problem, the applicant has developed a hair straightener that straightens or straightens the hair with hot air, which can effectively avoid the problem of hair damage caused by direct contact of the heating body with the hair.

[0003] In order to realize the connection of the air duct between the handle and the movable hairpin plate, a connecting component that can connect the air outlet end of the handle and the air inlet end of the hairpin plate needs to be provided. The present application aims to provide an air guide structure that is easy to install and can still ensure the connection between the air outlet end of the handle and the air inlet end of the hairpin plate when the hairpin plate is movable, and ensure its sealing. Summary of the invention

[0004] In view of the shortcomings of the prior art, the present invention provides an air guide structure for a hair straightener.

[0005] In order to solve the above technical problems, the present invention is solved by the following technical solutions: an air guide structure of a hair straightener, comprising a handle and hair clamps hinged on both sides of the handle and arranged opposite to each other, the handle comprising a first shell and a second shell assembled together at axial end faces, the first shell and the second shell being assembled together at the inner wall of the air outlet end side to form an annular groove, a plurality of positioning holes are arranged on the annular surface of the air inlet end of the air guide elastic member, the outer wall of the positioning ring has a plurality of positioning protrusions inserted into the positioning holes, the outer wall of the positioning ring is provided with an annular protrusion, the annular protrusion is limited in the annular groove, the outer wall of the positioning ring and the inner wall of the handle clamp the annular surface of the air inlet end of the air guide elastic member, the air outlet end of the air guide elastic member is forked into two air guide tubes corresponding to each other and connected to the air delivery cavities in the two hair clamps, the outer periphery of the air guide tube is provided with an annular elastic limiting portion, and the annular elastic limiting portion is clamped in the opening of the air delivery cavity. The air guide structure of the hair straightener ensures that the air outlet end of the handle is connected to the air inlet end of the hair clamp plate when the hair clamp plate is in an active state; the outer wall of the positioning ring and the inner wall of the handle clamp the annular surface of the air inlet end of the air guide elastic member to improve the sealing performance; the positioning protrusion is inserted into the positioning hole, and the annular groove is spliced ​​by the first shell and the second shell to position the annular protrusion, which can improve the assembly efficiency and ensure reliable positioning.

[0006] In the above technical solution, preferably, the two hairpin plates include a rotating arm, an air delivery shell and an air guide plate, the air delivery shell is clamped between the rotating arm and the air guide plate, the air delivery shell and the air guide plate are assembled to form the air delivery cavity and a first strip air outlet connected to the air delivery cavity, and the air inlet end of the air delivery cavity is connected to the air guide tube.

[0007] In the above technical solution, preferably, a second strip air outlet is provided on one side of the hair clamp plate, and the air outlet direction of the first strip air outlet is toward the second strip air outlet. With this structure, when the two hair clamp plates are closed and do not clamp hair, the air outlet of the first strip air outlet will blow toward the second strip air outlet along the gap between the two hair clamp plates, and blow out from the second strip air outlet, so that it can be used as a hair dryer.

[0008] In the above technical solution, preferably, the second strip-shaped air outlets on the two hairpin plates face an angle facing away from the outside. After the hot air is discharged from the first strip-shaped air outlet, it faces the second strip-shaped air outlet. The second strip-shaped air outlets on the two hairpin plates face an angle facing away from the outside. Therefore, the two second strip-shaped air outlets blow out the air obliquely outward, so that the hair below them is guided to both sides, expanding the evaporation area on the surface of the hair, making the hair drying more efficient; and when the hairpin plates are closed and not clamping the hair, hot air can be blown out from the second strip-shaped air outlet and used as a hair dryer alone. Since the two second strip-shaped air outlets blow out the air obliquely outward, the blowing range is larger, and the hair can be blown to both sides, making the hair drying more efficient.

[0009] In the above technical solution, preferably, the air guide plate has an arc-shaped air induction surface near the second strip air outlet, the end of the arc-shaped air induction surface abuts against the inner wall of the rotating arm, and the second strip air outlets on the two hairpin plates are located on the inner side of the two arc-shaped air induction surfaces. The arc-shaped air induction surface guides the air, so that the airflow blown out from the first strip air outlet can be smoothly guided to the second strip air outlet, and blown out along the outlet direction of the second strip air outlet, reducing the kinetic energy loss of the airflow.

[0010] In the above technical solution, preferably, a plurality of obliquely arranged air guides are provided on the inner side wall of the rotating arm, and the plurality of air guides divide the second strip-shaped air outlet into a plurality of sections, and the outlets of the gaps between the plurality of air guides face in a direction away from the handle. With this structure, when the hairpins clamp the hair to straighten, straighten, shape or blow dry the hair, long wet hair may drip water droplets, which may cause the pants or shoes to get wet. With this structure, the air guides the air through the air guides, so that the airflow blown out is diagonally outward away from the direction of the handle, so that the hair as a whole deviates diagonally outward for a distance, thereby preventing the long wet hair from dripping water droplets onto the pants or shoes.

[0011] Compared with the prior art, the present invention has the following beneficial effects: the air guide structure of the hair straightener still ensures that the air outlet end of the handle is connected to the air inlet end of the hair clamp plate when the hair clamp plate is in an active state; the outer wall of the positioning ring and the inner wall of the handle clamp the annular surface of the air inlet end of the air guide elastic member to improve the sealing performance; and the annular protrusion is positioned by inserting the positioning protrusion into the positioning hole and by combining the annular groove of the first shell and the second shell, so that the assembly efficiency can be improved and the positioning is reliable.

[0019] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments: Figures 1 to 7A wind guide structure of a hair straightener comprises a handle 1 and hairpin plates 2 which are hingedly connected to the handle 1 and are arranged opposite to each other on both sides. The handle 1 comprises a first shell 11 and a second shell 12 which are assembled at the axial end faces. The first shell 11 and the second shell 12 are assembled at the inner wall of the air outlet end side to form an annular groove 110. A plurality of positioning holes 42 are arranged on the annular surface of the air inlet end of the wind guide elastic member 4. The outer wall of the positioning ring 43 has a plurality of positioning protrusions 44 which are inserted into the positioning holes 42. The outer wall of the positioning ring 43 is provided with an annular protrusion 45 which is limited in the annular groove 110. The outer wall of the positioning ring 43 and the inner wall of the handle 1 clamp the annular surface of the air inlet end of the wind guide elastic member 4. The air outlet end of the wind guide elastic member 4 is bifurcated into two wind guide tubes 41 which are connected to the air delivery chambers 24 in the two hairpin plates 2 in a one-to-one correspondence. The outer periphery of the wind guide tube 41 is provided with an annular elastic limiting portion 411 which is clamped in the opening of the air delivery chamber 24. The air guide structure of this hair straightener still ensures that the air outlet end of the handle is connected to the air inlet end of the hair clamp plate when the hair clamp plate is in an active state. The outer wall of the positioning ring 43 and the inner wall of the handle 1 clamp the annular surface of the air inlet end of the air guide elastic member 4 to improve the sealing performance. The positioning protrusion 44 is inserted into the positioning hole 42, and the annular groove 110 is spliced ​​by the first shell 11 and the second shell 12 to position the annular protrusion 45, which can improve the assembly efficiency and ensure reliable positioning.

[0020] In this embodiment, the two clamping plates 2 include a rotating arm 21, an air delivery shell 22 and an air guide plate 23. The air delivery shell 22 is clamped between the rotating arm 21 and the air guide plate 23. The air delivery shell 22 and the air guide plate 23 are assembled to form an air delivery cavity 24 and a first strip air outlet 26 connected to the air delivery cavity 24. The air inlet end of the air delivery cavity 24 is connected to the air guide tube 41.

[0021] In this embodiment, a second strip air outlet 28 is provided on one side of the hair clamp plate 2, and the air outlet direction of the first strip air outlet 26 is toward the second strip air outlet 28. With this structure, when the two hair clamp plates 2 are closed and do not clamp hair, the air outlet of the first strip air outlet 26 will blow toward the second strip air outlet 28 along the gap between the two hair clamp plates, and blow out from the second strip air outlet 28, so that it can be used as a hair dryer.

[0022] In this embodiment, the second strip air outlets 28 on the two hair clamps 2 face at an angle facing away from the outside. After the hot air is discharged from the first strip air outlet 26, it faces the second strip air outlet 28. The second strip air outlets 28 on the two hair clamps 2 face at an angle facing away from the outside. Therefore, the two second strip air outlets 28 blow out the air obliquely outward, so that the hair below them is guided to both sides, expanding the evaporation area of ​​the hair surface, making the hair drying more efficient; and when the hair clamps 2 are closed and not clamping hair, hot air can be blown out from the second strip air outlets 28 and used as a hair dryer alone. Since the two second strip air outlets 28 blow out the air obliquely outward, the blowing range is larger, and the hair can be blown to both sides, making the hair drying more efficient.

[0023] In this embodiment, the air guide plate 23 has an arc-shaped air induction surface 231 near the second strip air outlet 28, the end of the arc-shaped air induction surface 231 abuts against the inner wall of the rotating arm 21, and the second strip air outlet 28 on the two hairpin plates 2 is located on the inner side of the two arc-shaped air induction surfaces 231. The arc-shaped air induction surface guides the air, so that the airflow blown out from the first strip air outlet can be smoothly guided to the second strip air outlet, and blown out along the outlet direction of the second strip air outlet, reducing the kinetic energy loss of the airflow.

[0024] In this embodiment, a plurality of obliquely arranged air guide pieces 211 are provided on the inner side wall of the rotating arm 21. The plurality of air guide pieces 211 divide the second strip-shaped air outlet 28 into a plurality of sections, and the outlets of the gaps between the plurality of air guide pieces 211 face in a direction away from the handle 1. With this structure, when the hairpin 2 clamps the hair to straighten, straighten, or blow dry the hair, long wet hair may drip water droplets, which may cause the pants or shoes to get wet. With this structure, the air guide piece 211 guides the air, so that the blown air flow is diagonally outward away from the direction of the handle 1, so that the hair as a whole deviates diagonally outward for a distance, thereby preventing the long wet hair from dripping water droplets onto the pants or shoes.

[0025] The above are only preferred embodiments of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
