Description

Technical Field

[0001] The utility model belongs to the technical field of hair straighteners, and particularly relates to a structure of an air-supply hair straightening clamp. Background Art

[0002] Hair straighteners and hair curlers are commonly used hair styling tools at present. And currently, what is needed is a hair straightener that has both the functions of straightening and curling hair to achieve dual-functional use. In order to enhance the styling effect of straightening and curling hair, generally, a fan is arranged inside the clamp of the hair straightener, and the fan blows air flow towards the hair, so that the hair is evenly heated, etc.

[0003] The Chinese patent document with the publication number CN220756795U discloses a hair straightener hair dryer, which includes a straightening unit, comprising two arms hinged at one end, and two straightening plates opposite to each other are arranged on the styling surfaces of the two arms; a hair dryer unit, including a air-supply air duct located on one arm and an air flow channel on the other arm, the air flow channel is opposite to the air outlet of the air-supply air duct and guides the air flow to flow out, and the air outlet of the air-supply air duct is located beside the two straightening plates; a control unit, arranged on any one of the arms, and the control unit controls the straightening unit and the hair dryer unit to work independently or jointly, entering a straightening mode, a hair drying mode or a straightening and hair drying mode. The said air-supply air duct has an air inlet and an air outlet, a motor and a first heating element are arranged inside the air-supply air duct, and the air flow blows out from the air inlet through the motor and the heating element from the air outlet. By arranging an air-supply air duct inside one of the arms and an air flow channel on the styling surface, the air flow channel forms a guide for the air flow conveyed by the air-supply air duct (i.e., forms a direct blow), effectively preventing air flow turbulence, and basically not reducing the air flow velocity and not affecting the air volume, thereby shortening the styling time and improving the styling efficiency; at the same time, after the air flow is guided, it effectively avoids the air flow blowing onto the straightening plates and affecting the heat of the straightening unit.

[0004] In the technical solution of the above patent document, the air flow blows upwards from the air-supply channel and blows out from the air flow channel, so as to blow the hair clamped between the upper clamp and the lower clamp, making the hair evenly heated, etc. However, when realizing the curling function, when the upper clamp and the lower clamp clamp the hair and wind the hair around the outside of the upper clamp and the lower clamp, since the air flow blows out from the air flow channel, the hair wound around the outside can only be locally affected by the air flow, so that the locally clamped hair has a better styling effect, while the hair not passing through the air flow has a poor styling effect, and shows an obvious stepped styling effect, resulting in the problem of poor curling styling effect of the hair.

[0035] Referring to Figures 6 to 8 , the upper clamping plate 200 includes an upper housing 210, a second cover plate 220, and a second heating element 230. A second connection portion 201 is provided at one end of the upper housing 210. The second connection portion 201 is rotatably connected to the first connection portion 103.

A flow dividing member 240 is provided in the cavity 203. The flow dividing member 240 includes a plurality of air flow grooves 241. One end of the air flow grooves 241 communicates with the air permeation hole 222, and the other end of each air flow groove 241 is provided with a plurality of air outlet holes 211 penetrating through the upper housing 210.

[0036] When the hair straightening and blowing clamp of the above embodiment heats and shapes the hair, the hair can be clamped between the upper clamping plate 200 and the lower clamping plate 100, and the first electric heating element 120 and the second electric heating element 230 are energized to generate heat to realize heating the hair. When straightening the hair, clamp the hair and pull it down along the direction of the hair end, so as to achieve the effect of straight hair. And during the straightening process, the blowing device 140 blows air into the air duct 102, so that the air flow blows from the air blowing holes 133 to the air permeable holes 222, so that the hair can receive uniform air flow; thereby ensuring the straightening effect. When curling the hair, the upper clamping plate 200 and the lower clamping plate 100 clamp the hair, and then wind the hair around the outside of the overall structure formed by the upper clamping plate 200 and the lower clamping plate 100. While the first electric heating element 120 and the second electric heating element 230 heat the hair, the blowing device 140 blows air into the air duct 102, so that the air flow blows from the air blowing holes 133 to the air permeable holes 222 and enters the air flow groove 241, and then blows out from the air outlet hole 221 of the upper housing 210. Since the flow dividing member 240 includes a plurality of air flow grooves 241 and air outlet holes 211 are provided at the air outlet ends of the respective air flow grooves 241, the air flow can be evenly dispersed and blown onto the hair, so that the hair is heated or cooled evenly, thereby ensuring the hair curling and shaping effect.

[0037] Further, please refer to Figure 2 and Figure 5 In the installation cavity 101, a corrugated heater 150 is further provided, and the corrugated heater 150 is located between the blowing device 140 and the air blowing holes 133. The corrugated heater 150 is an aluminum profile including a plurality of corrugated fins and a PCT heating element arranged in the aluminum profile, so that the air flow formed by the blowing device 140 can be better heated. The blown air flow is a hot air flow, which can better heat and shape the hair, etc.

[0038] Furthermore, the corrugated heater 150, each first electric heating element 120 and each second electric heating element 230 can be independently heated or heated simultaneously. Therefore, when straightening or curling the hair, hot air can be used for heating, or cold air can be used to shape the heated hair.

[0039] Further, please refer to Figure 2 、 Figure 3 and Figure 5 A bottom shell 160 is provided in the first installation position 111, a first cover plate 130 covers the opening of the bottom shell 160, and a flow guiding member 170 is further provided in the bottom shell 160. The flow guiding member 170 is located on the bottom side of the first cover plate 130, and the flow guiding member 170 is used for splitting the air flow formed in the air duct 102. So that the air flow can be evenly guided to each air blowing hole 133, making the air flow distribution more uniform.

[0040] Further, please refer to Figure 5The flow guide 170 includes a plurality of wind shields 171 arranged in sequence, and the wind shields 171 have wind ports 172 tilted downward toward the blowing device 140, and openings 173 toward the first cover plate 130. The lowest end of the wind ports 173 of each wind shield 171 is gradually lowered. Therefore, the airflow can enter the wind shield 171 from the wind ports 172, and then blow air from the openings 173 to the blowing holes 133. As the height of the wind ports 172 gradually decreases, each wind port 172 can evenly inlet air.

[0041] For further information, please refer to Figure 8 The flow divider 240 includes a plurality of partitions 242 arranged in a fan shape, an air flow slot 241 is formed between two adjacent partitions 242 , and a rib plate 243 is provided between two adjacent partitions 242 .

[0042] For further information, please refer to Figure 7 The second electric heating element 230 includes a heat-conducting shell 231, a PTC heating element 232 and an elastic element 233. The PTC heating element 232 is arranged in the heat-conducting shell 231, the heat-conducting shell 231 is limited in the second concave cavity 221, and the elastic element 233 is arranged between the PTC heating element 232 and the top side of the second concave cavity 221. Therefore, the second electric heating element 230 can float up and down elastically. The problem of clamping the hair will not cause the hair to be pulled or broken by hard contact with the hair.

[0043] Furthermore, the second electric heating element 230 is a PCT heating element disposed in the first cavity 131 .

[0044] For further information, please refer to Figure 1 , Figure 2 , Figure 4 and Figure 5 The top side of one end of the lower housing 110 is covered with a handle cover 112, and the handle cover 112 and the lower housing 110 form a cavity, and the blowing device 140 is arranged in the cavity. One side of the handle cover 112 has a mouth 113, and the first connecting part 103 is arranged in the mouth 113. Therefore, part of the airflow can enter the upper housing 210 to dissipate heat and cool down the electronic components in the upper housing 210.

[0045] For further information, please refer to Figure 6 The handle cover 112 is also provided with a self-locking member 114, and a plug plate 115 is extended from the self-locking member 114. A limit plate 212 is extended from the bottom side of the upper shell 210, and the limit plate 212 is provided with a socket 213, and the socket 213 is used to cooperate with the plug plate 115. Specifically, after the upper clamping plate 200 and the lower clamping plate 100 are clamped, the self-locking member 114 can be pushed to insert the plug plate 115 into the socket 213, thereby limiting the upper clamping plate 200 and avoiding the problem of the upper clamping plate 200 opening.

[0046] Further, refer to Figure 2, an elastic limiting member 300 is further provided at one end of the upper housing 210 and / or the lower housing 110 away from the blowing device, and the elastic limiting member 300 is used to limit and clamp the hair between the upper clamping plate 200 and the lower clamping plate 100.

[0047] More preferably, elastic limiting members 300 are provided on both the bottom side of the upper housing 210 and the top side of the lower housing 110. And when the upper clamping plate 200 and the lower clamping plate 100 are clamped together, the two elastic limiting members 300 are also clamped together and can be compressed without interfering with the clamping of the hair by the upper clamping plate 200 and the lower clamping plate 100.

[0048] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
