Description

Technical Field

[0001] The invention relates to the technical field of beauty and hairdressing tools, in particular to a hair straightener with comb teeth and a floating structure. Background Art

[0002] Hair straighteners are widely used in the hairdressing industry to achieve hair straightening. Since the comb teeth and heating plate components of traditional hair straighteners with comb teeth are structures that cannot be raised or lowered, the comb teeth are easily deformed when pulling hair, and it is not possible to flexibly select the comb teeth or non-comb teeth function. This further causes the heating plate to not fit the hair well when the hair straightener is pulling hair, and the hair is heated unevenly, thereby affecting the hair pulling efficiency and the hair straightening effect. For this reason, although some people have invented a hair straightener with floating comb teeth, this floating structure is complex in structure, greatly increasing the difficulty of product assembly and manufacturing; secondly, it will further deepen the degree of deformation of the comb teeth when pulling hair, which will more seriously affect the effect of straightening hair. Summary of the invention

[0003] In view of the shortcomings of the prior art, the present invention provides a hair straightener with a floating heating plate and comb teeth, which has a simpler structure, a more reasonable design, a heating plate that can better fit the hair, and comb teeth that will not be deformed and has a better hair straightening effect.

When the pressing portion presses against the abutment portion, the first heating component cannot be pressed down, and the aluminum plate is basically flush with the tooth tips of the comb teeth; when the pressing portion staggers against the abutment portion, the first heating component can be pressed down, and after being pressed down, the aluminum plate is in a concave state relative to the comb teeth, and it does not contact the hair. At this time, the hair is directly combed and straightened by the comb teeth, thereby realizing the function of switching whether to have comb teeth.

[0006] Furthermore, a guide column and a limit foot are provided on the inner wall of the first housing, and a strip-shaped guide hole, a limit hole and a avoidance hole are provided in the push rod at positions corresponding to the guide column, the limit foot and the floating spring, and the guide column, the limit foot and the floating spring pass through the guide hole, the limit hole and the avoidance hole respectively. The guide column and the guide hole are used to move the push rod in a set forward and backward direction, and the limit foot and the limit hole are used to move the push rod a set distance so that the pressing part can be just aligned with the abutting part.

The first housing is fixedly hinged to the second housing through a hinge shaft, and the power cord assembly is connected from the tail of the second housing.

[0014] Of course, it should be noted separately that one of the first heating assembly and the second heating assembly can be designed to be floating, or both can be floating. The comb tooth assembly can also be designed to be height-adjustable, but this may lead to a more complex structure.

[0015] In the present invention, by designing the first heating assembly beside the comb tooth assembly, the heating plate of the first heating assembly can float relative to the comb teeth, achieving the effect of comb tooth floating. This not only makes the floating structure simpler, but also ensures that the comb teeth will not deform during hair straightening. When the comb teeth are not needed, the heating plate can be adjusted to a fixed structure through the floating control mechanism, making the hair straightening surface of the heating plate flush with the height of the comb teeth, so that the hair does not pass through the comb teeth during hair straightening. When the comb teeth are needed, the heating plate can be adjusted to a floating structure through the floating control mechanism, making the hair straightening surface of the heating plate lower than the height of the comb teeth when stressed. At this time, the hair to be straightened passes through the comb teeth for combing and straightening, achieving a better hair straightening effect. In addition, the upper and lower heating plates can float and swing back and forth, left and right through springs, and can better conform to the hair during hair straightening, further improving the hair straightening effect.

[0030] A positioning shaft 44 is horizontally penetrated through the middle position of the fixing bracket 43. At a position corresponding to the positioning shaft 44 on the inner wall of the first housing 1, there is provided a shaft bracket 14. Both ends of the positioning shaft 44 are embedded in the shaft bracket 14, forming a positioning structure for the first heating component 4 during the floating process to limit the swing amplitude of the first heating component 4.

[0031] The heating component further includes a second heating component 7, and the second heating component 7 is installed in the second housing 2 to form a structure opposite to the first heating component 4.

[0032] The second heating component 7 includes an aluminum plate 71, a heater 72 and a fixing bracket 73. The heater 72 is installed in the aluminum plate 71 and is connected to the circuit board 8. The aluminum plate 71 is assembled and fixed with the fixing bracket 73, and the fixing bracket 73 is installed in the second housing 2. That is to say, the structure of the second heating component 7 is basically the same as that of the first heating component 1, except that its fixing bracket 73 does not need to be provided with an abutting part, and the aluminum plate 41 of the first heating component 4 and the aluminum plate 71 of the second heating component 7 are clamped, or the comb teeth of the first heating component 4 are abutted against the aluminum plate 71 of the second heating component 7 for hair pulling.

[0033] The fixing bracket 73 is installed in the second housing 2 through two support springs 75, so that the second heating component 7 forms a swingable structure, so that it can better fit the hair during hair pulling, which helps to improve the hair pulling effect; a positioning shaft 74 is horizontally penetrated through the middle position of the fixing bracket 73. At a position corresponding to the positioning shaft 74 on the inner wall of the second housing 2, there is provided a shaft bracket. Both ends of the positioning shaft 74 are embedded in the shaft bracket, forming a positioning structure for the second heating component 7 during the swinging process.

[0034] A heat insulation frame 76 is further arranged in the second housing 2. The heat insulation frame 76 is fixedly installed in the second housing 2 along the longitudinal direction of the second heating component 7, and the heat insulation frame 76 faces the comb tooth component 5. When the first heating component 4 is in a floating state and the hair straightener is closed, that is, when the first heating component 4 and the second heating component 7 are pressed against each other, the comb tooth component 5 is accommodated by the heat insulation frame 76. The comb tooth component 5 can be arranged on the left side, right side or middle position of the first heating component 4 according to needs.

At this time, the first heating component 4 can move vertically under the action of the spring 45, and the fixing frame 43 connected to the heating plate 41 will move downward under the downward pressing force, so that a drop is formed between the heating plate 41 and the comb teeth. The tips of the comb teeth of the comb tooth component 5 will be higher than the surface of the heating plate 41 and form a set drop distance. This drop distance is not limited to 4 mm. In this way, when pulling hair, the hair will pass through the comb teeth for combing and straightening.

[0037] As such Figure 9 As shown, when the push rod 62 slides to the 2nd gear (left side), the pressing portion 66 of the push rod 62 abuts against the abutting portion 46 of the fixing frame 43 directly. In this way, the fixing frame 43 connected to the heating plate 41 will not move downward under the downward pressing force, and the comb tooth component 5 will not protrude from the surface of the heating plate 41. In this way, when pulling hair, the hair will not pass through the comb teeth.

The above description is only the preferred embodiment of the present invention, and it cannot limit the scope of implementation of the present invention. That is, all equal changes and modifications made according to the scope of this application should still fall within the scope covered by the present invention.
