Description

Technical Field

[0001] This utility model relates to the technical field of beauty and hairdressing tools, and in particular to a hair straightener. Background Technology

[0002] Existing automatic hair straighteners that replace manual clamping have a very poor user experience. When the automatic clamping force is high, the upper and lower clamping mechanisms fit tightly together, providing pre-pressure to the hair during use, which can achieve a good straightening effect. This effect is fine when there is a lot of hair to style, but when styling near the ends of the hair, because there is very little hair, the excessive pre-pressure clamps the ends tightly, directly causing hair to be pulled and broken. Utility Model Content

[0003] The main purpose of this invention is to provide a hair straightener that reduces hair breakage and improves the user experience.

[0004] To achieve the above objectives, the hair straightener proposed in this utility model includes:

[0005] The housing includes a fixed housing and a rotating housing, wherein the rotating housing is rotatably connected to the fixed housing;

[0006] An upper clamping plate and a lower clamping plate, wherein the upper clamping plate is connected to the rotating housing and the lower clamping plate is connected to the fixed housing;

[0007] A heating element, mounted on the housing, for heating the upper clamping plate and / or the lower clamping plate; and

[0008] A stop block is connected to the housing. When the upper clamping plate and the lower clamping plate are in a clamping state, the stop block abuts against the upper clamping plate or the lower clamping plate so that the upper clamping plate and the lower clamping plate are spaced apart.

[0009] In one embodiment, when the upper clamping plate and the lower clamping plate are in a clamped state, the distance between the upper clamping plate and the lower clamping plate is s, where 0.1mm≤s≤0.3mm.

[0010] In one embodiment, the stop is made of a flexible material.

[0011] In one embodiment, the hair straightener further includes a floating structure installed between the rotating housing and the upper clamping plate, and / or, the floating structure is installed between the fixed housing and the lower clamping plate.

[0012] In one embodiment, the stop is connected to the upper clamping plate or the lower clamping plate to float with the floating structure. The stop is disposed near the end of the lower clamping plate away from the housing gripping part, and the stop is disposed opposite to the upper clamping plate or the lower clamping plate.

[0013] In one embodiment, the upper clamping plate and the lower clamping plate are spaced apart at the ends away from the stop block.

[0014] In one embodiment, the floating structure includes floating silicone, which is sandwiched between the rotating housing and the upper clamping plate, and / or, the floating silicone is sandwiched between the fixed housing and the lower clamping plate.

[0015] In one embodiment, the rotating housing and / or the fixed housing are provided with limiting grooves, and the floating silicone limiting connection is connected to the corresponding limiting groove.

[0016] In one embodiment, the hair straightener further includes a torsion spring, one torsion arm of which is connected to the fixed housing and the other torsion arm of which is connected to the rotating housing, so that the upper clamp is rotatably connected to the fixed housing.

[0017] In one embodiment, a pressing plate is connected to the rotating housing. The pressing plate is arc-shaped to allow the upper clamping plate and the lower clamping plate to switch between the clamped state and the open state.

[0018] The hair straightener of this utility model includes a housing, an upper clamping plate, a lower clamping plate, a heating element, and a stop block. The housing includes a fixed housing and a rotating housing, with the rotating housing rotatably connected to the fixed housing. The upper clamping plate is connected to the rotating housing, and the lower clamping plate is connected to the fixed housing. The heating element is installed on the housing to heat the upper clamping plate and / or the lower clamping plate. The stop block is connected to the housing. When the upper and lower clamping plates are in a clamping state, the stop block abuts against the upper or lower clamping plate, so that the upper and lower clamping plates are spaced apart. This ensures that when the user styles their hair to the ends, even if the hair volume is small, the hair straightener will not clamp too tightly due to the gap between the upper and lower clamping plates. This reduces the likelihood of hair pulling and breakage, thus reducing user pain and improving the user experience. Attached Figure Description

[0031] Reference Figure 1 , Figure 3 and Figure 5 This utility model proposes a hair straightener, comprising:

[0032] The housing includes a fixed housing 11 and a rotating housing 12, wherein the rotating housing 12 is rotatably connected to the fixed housing 11;

[0033] Upper clamping plate 21 and lower clamping plate 22, wherein the upper clamping plate 21 is connected to the rotating housing 12 and the lower clamping plate 22 is connected to the fixed housing 11;

[0034] A heating element 30, mounted on the housing, is used to heat the upper clamping plate 21 and / or the lower clamping plate 22; and

[0035] The stop block 40 is connected to the housing. When the upper clamping plate 21 and the lower clamping plate 22 are in a clamping state, the stop block 40 abuts against the upper clamping plate 21 or the lower clamping plate 22 so that the upper clamping plate 21 and the lower clamping plate 22 are spaced apart.

[0036] The hair straightener of this utility model includes a housing, an upper clamping plate 21, a lower clamping plate 22, a heating element 30, and a stop block 40. The housing includes a fixed housing 11 and a rotating housing 12. The rotating housing 12 is rotatably connected to the fixed housing 11. The upper clamping plate 21 is connected to the rotating housing 12, and the lower clamping plate 22 is connected to the fixed housing 11. The heating element 30 is installed on the housing to heat the upper clamping plate 21 and / or the lower clamping plate 22. The stop block 40 is connected to the housing. When the upper clamping plate 21 and the lower clamping plate 22 are in a clamping state, the stop block 40 abuts against the upper clamping plate 21 or the lower clamping plate 22, so that the upper clamping plate 21 and the lower clamping plate 22 are spaced apart. This ensures that when the user styles the hair to the ends of the hair, even if the hair volume is small, the hair straightener will not clamp too tightly because there is a certain gap between the upper clamping plate 21 and the lower clamping plate 22. This reduces the occurrence of hair pulling and breakage by the hair straightener, thereby reducing the user's pain and improving the user experience.

[0037] Reference Figure 2 and Figure 3 Specifically, when the upper clamping plate 21 and the lower clamping plate 22 are in a clamped state, the distance between the upper clamping plate 21 and the lower clamping plate 22 is s, where 0.1mm ≤ s ≤ 0.3mm. Understandably, the diameter of a single human hair is approximately 0.1mm. Therefore, if s < 0.1mm, on the one hand, the processing precision between the upper clamping plate 21 and the lower clamping plate 22 will be too high, increasing the processing difficulty of the hair straightener and thus increasing its manufacturing cost; on the other hand, the gap between the upper clamping plate 21 and the lower clamping plate 22 will be too small, causing users to easily pull and even break their hair during the straightening process, resulting in user discomfort. Conversely, if s > 0.3mm, the gap between the upper clamping plate 21 and the lower clamping plate 22 will be too large, making it difficult for users to firmly clamp their hair when styling the ends or when the hair volume is small, resulting in poor styling effects and failing to meet user expectations. Therefore, by reducing the processing precision of the hair straightener to 0.1mm≤s≤0.3mm, the hair straightener's hair pulling and breakage are reduced, improving the styling effect and thus enhancing the user experience.

[0038] When the upper clamping plate 21 and the lower clamping plate 22 are in a heated state, the upper clamping plate 21 and the lower clamping plate 22 expand due to heat. At this time, the distance between the upper clamping plate 21 and the lower clamping plate 22 in the clamped state is between 0.1 mm and 0.2 mm. When at room temperature, the distance between the upper clamping plate 21 and the lower clamping plate 22 in the clamped state is between 0.15 mm and 0.3 mm.

[0039] Furthermore, the stop block 40 is made of a flexible material. Understandably, some users may have hair with a diameter smaller than the distance between the upper clamp plate 21 and the lower clamp plate 22 when the hair is clamped, such as the ends of their hair or a small portion of their hair with a smaller diameter. This can prevent the hair from being firmly clamped by the upper clamp plate 21 and the lower clamp plate 22, resulting in a less than desired styling effect. Therefore, by making the stop block 40 a flexible material, when the user's hair cannot be clamped by the upper clamp plate 21 and the lower clamp plate 22 when the hair is clamped, the user only needs to manually press the fixing housing 11 and rotate the housing 12. This causes the flexible stop block 40 to deform, thereby reducing the distance between the upper clamp plate 21 and the lower clamp plate 22 when the hair is clamped. This allows hair with a smaller diameter to still be clamped by the upper clamp plate 21 and the lower clamp plate 22, thus achieving the desired styling effect. The flexible material can be rubber, silicone, or other materials that can withstand high temperatures. This prevents the upper clamp 21 and lower clamp 22 from deforming or hardening of the stop block 40 during the heating process, thereby increasing the service life of the stop block 40. At the same time, rubber and silicone are inexpensive, thus reducing the production cost of the hair straightener.

[0040] Of course, in other embodiments, the stop 40 can also be made of a rigid material. The stop 40 is elastically connected to the housing by springs or other elastic elements, so that the user can still reduce the gap between the upper clamping plate 21 and the lower clamping plate 22 in the clamped state by clamping and rotating the housing 12 and fixing the housing 11, thereby achieving the desired shaping effect.

[0041] Reference Figures 1 to 5 In one embodiment, the hair straightener further includes a floating structure installed between the rotating housing 12 and the upper clamping plate 21, and / or, the floating structure installed between the fixed housing 11 and the lower clamping plate 22. Understandably, hair thickness varies at different locations, such as near the scalp and at the ends, bangs and the back of the head. Fixed-spaced clamping plates can apply excessive pressure when clamping thicker hair strands, damaging the hair; when clamping thinner hair strands, they may result in poor straightening due to insufficient contact. The floating structure allows the upper clamping plate 21 and / or the lower clamping plate 22 to move up and down within a small range, automatically adjusting the clamping plate spacing according to the actual thickness of the hair strand. This ensures that relatively uniform and moderate pressure is always applied to the hair, regardless of its thickness. For curly or tangled hair, fixed clamping plates may excessively pull the hair when pulled. The floating structure allows the plates to bounce slightly when encountering resistance, reducing the physical pulling force on the hair, thus making the hair straightener smoother and easier to use, thereby improving the user experience.

[0042] Preferably, the stop block 40 is connected to the upper clamping plate 21 or the lower clamping plate 22 to float with the floating structure. The stop block 40 is positioned near the end of the lower clamping plate 22 away from the housing grip, and is positioned opposite to the upper clamping plate 21 or the lower clamping plate 22. This facilitates the installation of the stop block 40. Furthermore, when the upper clamping plate 21 and the lower clamping plate 22 are in the clamped state, the upper clamping plate 21 and the stop block 40 are in close contact, thereby increasing the contact area between the upper clamping plate 21 and the stop block 40, reducing the possibility of tilting or shifting when the upper clamping plate 21 is clamped, and thus improving the stability of the hair straightener. Of course, in other embodiments, the stop block 40 can also be located on both sides of the lower clamping plate 22 in the width direction and then extend inward, so that when the upper clamping plate 21 and the lower clamping plate 22 are in the clamped state, the stop block 40 is clamped between the upper clamping plate 21 and the lower clamping plate 22. Furthermore, the stop block 40 is disposed on the upper clamping plate 21 or the lower clamping plate 22, so that the stop block 40 can float up and down with the floating structure, thereby maintaining a predetermined gap between the upper clamping plate 21 and the lower clamping plate 22, thereby improving the stability and reliability of the hair straightener. Of course, in other embodiments, the stop block 40 may also be disposed at the end of the lower clamping plate 22 near the housing grip portion.

[0043] In one embodiment, the upper clamping plate 21 and the lower clamping plate 22 are spaced apart at their ends away from the stop block 40. Understandably, although the stop block 40 is positioned near the lower clamping plate 22 to create a certain distance between the upper clamping plate 21 and the lower clamping plate 22, the large span in the length direction of the upper clamping plate 21 and the lower clamping plate 22 means that the ends of the upper clamping plate 21 and the lower clamping plate 22 away from the stop block 40 may come into contact, potentially causing hair to easily break between them. Therefore, by spaced apart at the ends of the upper clamping plate 21 and the lower clamping plate 22 away from the stop block 40, the likelihood of hair breaking at these ends when clamped is reduced, thus improving the user experience.

[0044] Specifically, the floating structure includes a floating silicone rubber 50, which is sandwiched between the rotating housing 12 and the upper clamping plate 21, and / or sandwiched between the fixed housing 11 and the lower clamping plate 22. The floating silicone rubber 50 has a simple structure, and the contact between the floating silicone rubber 50 and the upper clamping plate 21 and / or the lower clamping plate 22 is surface-to-surface, resulting in a larger contact area. This makes it less likely for the upper clamping plate 21 and / or the lower clamping plate 22 to tilt during floating, thereby improving the stability and reliability of the hair straightener. Simultaneously, the floating silicone rubber 50 has a low cost, thus reducing the operating cost of the hair straightener. Of course, multiple floating silicone rubber 50s can be spaced apart to increase the stability and reliability of the upper clamping plate 21 and / or the lower clamping plate 22 during floating. The floating structure can also be a spring, a floating rubber sheet, or a spring-like structure.

[0045] Furthermore, the rotating housing 12 and / or the fixed housing 11 are provided with limiting grooves 121, and the floating silicone 50 is limitedly connected to the corresponding limiting grooves 121. The limiting grooves 121 have a simple structure, which facilitates the production and processing of the housing, thereby reducing the production and manufacturing cost of the hair straightener.

[0046] Specifically, the hair straightener also includes a torsion spring 13, one torsion arm of which is connected to the fixed housing 11, and the other torsion arm of which is connected to the rotating housing 12, so that the upper clamping plate 21 is rotatably connected to the fixed housing 11. The main body of the torsion spring 13 is fixed to the fixed housing 11. The torsion spring 13 realizes the rotational connection between the rotating housing 12 and the fixed housing 11, thereby allowing the upper clamping plate 21 and the lower clamping plate 22 to switch between a clamped state and an open state. The torsion spring 13 has a simple structure, is easy to install, has stable and reliable performance, and is inexpensive, thereby improving the stability and reliability of the hair straightener.

[0047] In one embodiment, a pressing plate 14 is connected to the rotating housing 12. The pressing plate 14 is arc-shaped to allow the upper clamping plate 21 and the lower clamping plate 22 to switch between the clamped state and the open state. By providing the pressing plate 14, it is convenient for daily use. The arc shape reduces the possibility of the pressing plate 14 pinching the hand between itself and the fixed housing 11 during daily use, thereby improving the user experience.
