Referring to fig. 1, an embodiment of the present invention provides a hair straightener 1 for shaping hair by straightening or curling. The hair straightener 1 comprises a holding part 11 and two clamping components 12 connected with the holding part 11, wherein the working surfaces of the two clamping components 12 are arranged oppositely; at least one clamping component 12 is movably connected with the holding part 11 so as to switch the two clamping components 12 between closing and opening. When a user desires to style hair, the user first places the hair between the open clamping assemblies 12 and then closes the clamping assemblies 12 to style the hair.

Referring to fig. 2 and 3, further, at least one end of at least one of the clamping assemblies 12 close to the holding portion 11 is provided with at least one boss 121 extending toward another clamping assembly 12, and when the two clamping assemblies 12 are closed, the boss 121 allows a gap to be left between the two clamping assemblies 12. It can be understood that the boss 121 can enable a gap (a narrow gap with a thickness of H exists between the working surfaces of the two clamping components 12 in the closed state as shown in fig. 2) to be left between the two clamping components 12 without being completely attached, the two clamping components 12 maintaining a certain gap can reduce the clamping force on the hair when the two clamping components 12 are closed, the hair can smoothly pass through the gap between the two clamping components 12, and further damage to the hair caused by too large clamping force is avoided.

As an alternative embodiment, as shown in fig. 2 and 3, one of the two clamping assemblies 12 is provided with a boss 121, and the other clamping assembly is provided with a cavity 124 matched with the boss 121, the boss 121 is opposite to the cavity 124, and the height of the boss 121 is larger than the depth of the cavity 124, so that the boss 121 can be partially inserted into the cavity 124 when the two clamping assemblies 12 are closed. Through set up boss 121 on a centre gripping subassembly 12, set up cavity 124 on the position that another centre gripping subassembly 12 corresponds boss 121, can keep the clearance between two centre gripping subassemblies 12, carry on spacingly to two centre gripping subassemblies 12, avoid taking place to remove and wearing and tearing the hair in the relative position under two centre gripping subassemblies 12 closed condition.

Further, the cavity bottom of the cavity 124 is provided with an elastic body 125, and the boss 121 is inserted into the cavity 124 and compresses the elastic body 125. The elastic body 125 arranged at the bottom of the cavity can buffer the closing process of the two clamping components 12, the larger the closing degree is, the larger the required applied pressing force is, and the larger the potential risk of injury to the hair is, so that the force change of a user is fed back in advance, the user is reminded to pay attention to the adjustment of the pressing force to control the pressing force, and the hair injury caused by improper operation of the user is avoided.

As another alternative, the arrangement of the boss 121 may be: the two clamping assemblies 12 are provided with bosses 121 at opposite positions, so that the two bosses 121 abut against each other when the two clamping assemblies 12 are closed. It is understood that the two clamping assemblies 12 are provided with the bosses 121 at opposite positions, that is, one clamping assembly 12 is provided with the bosses 121, and the other clamping assembly 12 is also provided with the bosses 121 at corresponding positions, and the two bosses 121 extend oppositely. Can avoid unilateral boss 121 directly to support and lean on centre gripping subassembly 12 and need longer boss 121, both sides all set up boss 121 back boss 121 highly can reduce half, take shape more easily, but also can make the one set of production frock of spare part sharing that sets up boss 121 position in the centre gripping subassembly 12, reduction in production cost.

Referring to fig. 3 and 4, in particular, the cross-sectional area of the boss 121 in the vertical center line direction gradually decreases with the distance from the clamping assembly 12 where the boss 121 is located; the cross section area of the boss 121 in the direction perpendicular to the center line is gradually reduced from the root to the tail end, and the cross section area can be in the shapes of a pyramid, a cone, a frustum of a pyramid, a circular truncated cone and the like, the two clamping assemblies 12 can be gradually centered in the closing process, and the inclination is favorable for demoulding and forming during production and manufacturing, so that the rejection rate is reduced, and the product quality is ensured.

Specifically, the boss 121 is detachably connected to the clamping assembly 12 where the boss 121 is located. Boss 121 and centre gripping subassembly 12 can be dismantled and be connected, can replace under the condition of boss 121 wearing and tearing, and the user can select for use the boss 121 of suitable length according to how much of sending out the volume, the length of hair bundle, the thickness of hair silk moreover, and then obtains the clearance between the best centre gripping subassembly 12, and concrete structure can be that set up screw, jack or card chamber in the boss 121, and the adaptation sets up screw rod, bolt or dop on the centre gripping subassembly 12, also can adopt the bonding, inhale multiple different structural style such as magnetism.

With continued reference to fig. 1, 3 and 4, further, at least one clamping assembly 12 is provided with a stopper 122 extending toward another clamping assembly 12, and the other clamping assembly 12 is provided with a slot 123 corresponding to the stopper 122 and adapted to the stopper 122; the boss 121 is provided between the stopper 122 and the grip 11. It can be understood that the stopper 122 is disposed on a side of the protrusion 121 away from the grip portion 11, and can contact another clamping component 12 before the protrusion 121 acts, and be received in the slot 123, so as to prevent hair from entering an area where the protrusion 121 is located (as shown in fig. 1, a range of the working surface between the two clamping components 12 along the length direction of the clamping component 12 is limited by the stopper 122 on a side of the stopper 122 away from the protrusion 121), and thus prevent hair from being clamped at the protrusion 121, and even injuring the hair follicle or scalp during pulling. It should be noted that the slot 123 has a sufficient depth to ensure that the protrusion 121 plays a role of limiting the distance between the working surfaces when the two clamping assemblies 12 are combined, and the stop 122 is received in the slot 123 without interference.

It can be understood that the overall size of the main body of the hair straightener 1 (excluding the power cord and the plug) is usually 250-450 mm, and the minimum distance between the block 122 and the holding part 11 is 10-60 mm based on the preferred distance range provided by this embodiment. When the overall size of the main body portion of the hair straightener 1 is smaller or larger, the distance between the stopper 122 and the grip 11 is scaled in equal proportion. It will be appreciated that, since the stop 122 and the grip portion 11 both have a certain volume, the distance herein is the "minimum distance", i.e. the distance between the end of the stop 122 closest to the grip portion 11 and the end of the grip portion 11 closest to the stop 122. The stopper 122 is as close as possible to the holding portion 11, so that the working range of the holding member 12 is larger in the longitudinal direction, or the whole length of the hair straightener 1 is smaller when the working area is constant, and the distance between the boss 121 and the stopper 122 can be compact or loose, as long as the boss 121 is located between the stopper 122 and the holding portion 11, that is, the stopper 122 is located on the side of the boss 121 away from the holding portion 11.

As an alternative embodiment, a plurality of stoppers 122 are disposed on each of the two clamping assemblies 12, and the plurality of stoppers 122 are staggered, and the plurality of stoppers 122 are equidistant from the holding portion 11. It will be appreciated that the provision of the projection 121 on only one of the clamping assemblies 12 requires a greater length, and that the provision of a plurality of stops 122 on both clamping assemblies 12 reduces the difficulty of manufacture, and that shorter stops 122 may also have greater strength and less flexibility, preventing bending of the stops 122. The plurality of stoppers 122 are staggered, so that the stoppers 122 do not interfere with each other when the clamping assembly 12 is closed. The plurality of stoppers 122 are spaced from the holding portion 11 at equal distances, so that the plurality of stoppers 122 occupy a larger proportion in the width direction of the holding member 12, and individual bent hairs are prevented from entering the area where the projection 121 is located from a position not blocked by the stoppers 122.

Specifically, when the stopper 122 is disposed on a certain clamping assembly 12, the length of the stopper 122 extending out of the clamping assembly 12 is greater than the distance between the corresponding positions of the two clamping assemblies 12 when the two clamping assemblies 12 are opened; when the two clamping assemblies 12 are provided with the stoppers 122, the sum of the lengths of the two stoppers 122 extending out of the respective clamping assemblies 12 is greater than the distance between the corresponding positions of the two clamping assemblies 12 when the two clamping assemblies 12 are opened. It will be appreciated that the length of the one-sided stop 122 or the sum of the lengths of the two-sided stops 122 is greater than the distance between the corresponding positions of the two clamping assemblies 12 when the two clamping assemblies 12 are opened, so that the stop 122 still effectively covers the boss 121 when the clamping assemblies 12 are opened, thereby preventing the hair from entering the area of the boss 121 and being clamped.

Referring to fig. 5 and 6, further, at least one of the clamping assemblies 12 includes a base 126 and a heating body 127 disposed on the base 126 and facing the other clamping assembly 12, and a detachably connected cover 128 is disposed on a side of the base 126 away from the other clamping assembly 12. It should be noted that one of the two clamping assemblies 12 may have a heating function, and the other is only for assisting in clamping and shaping, or both of the two clamping assemblies 12 may have a heating function so as to be more efficient and convenient. The heating body 127 is arranged to heat the hair to soften the hair, the housing 128 is arranged to rapidly cool the side of the hair bundle away from the heating body, the hair bundle is shaped, and the housing 128 is preferably made of stainless steel, aluminum or alloy thereof, magnesium alloy and other materials with high heat dissipation, so that the heat dissipation of the hair bundle can be accelerated, and the shaping process is accelerated.

Referring to fig. 6 and 7, in particular, the casing 128 is curved to partially surround the base 126 to form a heat dissipation cavity 129, and a plurality of heat dissipation holes 1282 are formed in the casing 128. The heat dissipation effect can be improved by arranging the cover 128 in a curved shape and half-surrounding the base 126 to form the heat dissipation cavity 129; by arranging a plurality of heat dissipation holes 1282 on the casing 128, the heat dissipation performance of the casing 128 can be further improved.

Furthermore, a side of base 126 corresponding to heat dissipation cavity 129 is provided with rib 1261 extending along the length direction of base 126, rib 1261 extends to abut against cover 128; the housing 128 is supported by the ribs 1261 to maintain the curved configuration.

Furthermore, a folded edge 1281 is arranged at the edge of the casing 128, and a matched clamping groove 1262 is arranged at the edge of the base 126 corresponding to the folded edge 1281. By arranging the folded edge 1281 at the edge of the shell 128 and the adaptive clamping groove 1262 at the edge of the base 126, the shell 128 can be conveniently disassembled and replaced.

Referring to fig. 8 to 10, it should be noted that the holding portion 11 does not necessarily need to be a special holding component other than the holding component 12, and may also be only an area on the holding component 12 convenient to hold during use, so that "two holding components 12 connected to the holding portion 11" may be a certain holding component 12 fixedly connected to the holding portion 11, and another holding component 12 rotatably connected to the holding portion 11, so as to form an opening angle structure in which the one-side holding component 12 is controlled to open and close; (as shown in fig. 8, a hair straightener 1) can also be an open angle structure, wherein two clamping assemblies 12 are rotatably connected with the holding part 11, so that the two clamping assemblies 12 are controlled to open and close together; (another version of the hair straightener 1' as shown in fig. 9) it is also possible to have two clamping assemblies 12 directly pivotally connected to form an open-angled configuration in which the two clamping assemblies 12 are controlled to open and close and the holding portion 11 is near the end of the connection. (a further version of a hair straightener 1 "as shown in fig. 10) furthermore, for a hair straightener 1 with two holding assemblies 12 parallel to each other, the solution can be applied also, i.e. the stop 122 is closer to the side of the working area of the holding assemblies 12, while the projection 121 is isolated by the stop 122 at the side away from the working area of the holding assemblies 12. (in FIGS. 8 to 10, H represents the distance between the working surfaces of the two clamp assemblies 12 in the closed state, and L represents the working surface area of the two clamp assemblies 12 in the longitudinal direction of the clamp assemblies 12.)

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the utility model, and any modifications, equivalents and improvements made within the spirit of the present invention are intended to be included within the scope of the present invention.
