[0035] To explain in detail the technical content, structural features, objectives and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0036] Please see Figure 1 The infrared hair styling iron 1000 of this utility model includes a hair styling iron body 100 and a grip body 200 for the user to hold, and the grip body 200 is connected to the hair styling iron body 100. Since this application is an improvement on the hair styling iron body 100, the structure of the grip body 200 will not be described in detail here.

[0037] Combination Figure 2 and Figure 3The hair stick body 100 includes an outer cylinder 10, an inner cylinder 20 located inside the outer cylinder 10, an infrared light-emitting module 30 located in the inner cylinder 20, and multiple first comb teeth 40 arranged radially on the inner cylinder 20 and extending outward through the side wall 11 of the outer cylinder 10. The root 41 of the first comb teeth 40 is connected to the inner cylinder 20, so that the first comb teeth 40 and the inner cylinder 20 are connected together, and the inner cylinder 20 provides support for the first comb teeth 40; the tail 42 of the first comb teeth 40 is suspended outside the side wall 11 of the outer cylinder 10, so that the first comb teeth 40 can not only comb hair, but also wrap hair strands around the side wall 11 of the outer cylinder 10 to achieve the purpose of styling hair; optionally, in Figure 6 In this example, the first comb tooth 40 is a slender column to improve its combing effect. Furthermore, the first comb tooth 40 is arranged in a "V" shape, with the root 41 forming a "V"-shaped bend. This design allows the first comb tooth 40 to be split in two by bending the slender column in the middle, thus reducing the number of first comb teeth used. Obviously, depending on actual needs, the first comb tooth 40 can also be other shapes, therefore... Figure 6 The above is the limit.

[0038] Combined Figures 8 to 11 As an example, the inner cylinder 20 includes a first splicing portion 20a and a second splicing portion 20b spliced ​​together along the radial direction of the first comb teeth 40, and a spliced ​​receiving cavity 20c formed by the first splicing portion 20a and the second splicing portion 20b, such that a portion of the spliced ​​receiving cavity 20c is located on the first splicing portion 20a and the remaining portion is located on the second splicing portion 20b; alternatively, in Figure 10 In this example, the first splicing portion 20a and the second splicing portion 20b are symmetrical to ensure they are the same size. This ensures that the splicing receiving cavity 20c and the first splicing groove 20d, second splicing groove 20e, first splicing side connecting channel 20f, and second splicing side connecting channel 20g, as described below, occupy the same positions on the first splicing portion 20a as they occupy on the second splicing portion 20b. Obviously, depending on actual needs, the first splicing portion 20a and the second splicing portion 20b can also be made to be different sizes. Therefore, it is not considered... Figure 10 The above is the limit.

[0039] The infrared emitting module 30 is assembled inside the splicing and receiving cavity 20c, where the inner cylinder 20 provides support for the infrared emitting module 30; alternatively, it can be... Figure 2 , Figure 3 and Figure 10In this example, the inner cylinder 20 is a light-transmitting structure; the infrared light-emitting module 30 includes a circuit board 31 and infrared light-emitting diodes 32 respectively disposed on opposite sides of the circuit board 31, one side of the circuit board 31 (e.g. Figure 10 The infrared light-emitting diode 32 on the upper side of the circuit board 31 is opposite to the first splicing portion 20a, and the other side of the circuit board 31 (e.g.) Figure 10 The infrared LED 32 on the lower side of the middle section is opposite to the second splicing part 20b, as shown in the status diagram. Figure 10 As shown; this makes the light-emitting surface of the inner cylinder 20 more uniform. More specifically, as follows:

[0040] like Figure 6 and Figure 7 As shown in the figure, as an example, both the first splicing part 20a and the second splicing part 20b have multiple radially arranged blind holes 21 on their side walls. The blind holes 21 are conical with a smaller inner diameter and a larger outer diameter. Therefore, after the root 41 of the first comb tooth 40 in a "V" shape is inserted into the blind hole 21, the opening degree of the first comb tooth 40 in a "V" shape can be limited by the side wall 211 of the blind hole 21. The state is shown in the figure. Figure 7 As shown.

[0041] like Figure 2 and Figure 3 As shown, the outer cylinder 10 and the inner cylinder 20 are arranged concentrically to ensure that the gaps between them are as consistent as possible, thus making them more compact. Furthermore, in conjunction with... Figure 1 and Figure 4 As an example, the outer cylinder 10 has a radial perforation 12 on its side wall 11 for the first comb tooth 40 to pass through in a gap fit. That is, the diameter of the radial perforation 12 is larger than the size of the first comb tooth 40, thereby ensuring that there is a gap between the first comb tooth 40 and the radial perforation 12, so as to meet the need for the infrared light emitted by the infrared light-emitting module 30 to be emitted from the radial perforation 12 and act on the user.

[0042] like Figure 2 and Figure 3 As shown, as an example, the hairbrush body 100 also includes a first heating element 50 and a negative ion generator 60. The side wall 11 of the outer barrel 10 has a first protruding structure 14 and a second protruding structure 15 protruding from the internal space 13 of the outer barrel 11. The first protruding structure 14 has a first mounting cavity 141 for assembling the first heating element 50, so that the outer barrel 10 can be heated by the first heating element 50, thereby softening the hair wrapped around the outer barrel 10 and achieving a good styling effect. The second protruding structure 15 has a second mounting cavity 151 for assembling the negative ion generator 60, so that the hair can be made smoother by the negative ion generator 60. Optionally, in... Figure 2 and Figure 3In this example, the first protruding structure 14 and the second protruding structure 15 are positioned opposite each other in the radiation direction of the first comb teeth 40, so that the central angle between the negative ion generator 60 and the first heating element 50 is approximately 180 degrees. Obviously, depending on actual needs, the central angle between the first protruding structure 14 and the second protruding structure 15 can be other values, therefore, it is not considered... Figure 2 and Figure 3 The above is for reference only. Specifically, in conjunction with... Figures 1 to 4 As an example, the first assembly cavity 141 penetrates the end face 17 of the outer cylinder 10, so that the first heating element 50 is installed in the first assembly cavity 141 in a direction parallel to the direction in which the first assembly cavity 141 penetrates the end face 17 of the outer cylinder 10; the second assembly cavity 151 penetrates the end face 17 and the side face 18 of the outer cylinder 10, so that the negative ion generator 60 is installed in the second assembly cavity 151 in a direction parallel to the direction in which the second assembly cavity 151 penetrates the end face 17 of the outer cylinder 10, and the negative ion generator 60 is not covered by the corresponding side face 18 of the outer cylinder 10. It should be noted that, although Figure 2 and Figure 3 The demonstration shows that the main body 100 of the heating element also includes a first heating element 50 and a negative ion generator 60. Obviously, depending on actual needs, a second heating element can be used to replace the negative ion generator 60 to achieve heating of both sides of the outer cylinder 10. Therefore, it is not considered... Figure 2 and Figure 3 The above description is for illustrative purposes only. Alternatively, in other embodiments, the generator body 100 may be made without the negative ion generator 60 or the second heating element.

[0043] For example Figure 2 and Figure 3 As shown, as an example, the inner cylinder 20 also includes a first splicing groove 20d and a second splicing groove 20e formed by the first splicing portion 20a and the second splicing portion 20b. The first splicing groove 20d is arranged facing opposite to the first protruding structure 14 in the radial direction of the first comb teeth 40, and the second splicing groove 20e is arranged facing opposite to the second protruding structure 15 in the radial direction of the first comb teeth 40, so that the first splicing groove 20d and the second splicing groove 20e are opposite to each other in the radial direction of the first comb teeth 40. Therefore, the first splicing groove 20d provides clearance for the first protruding structure 14, and the second splicing groove 20e provides clearance for the second protruding structure 15, thereby making the inner cylinder 20 and the outer cylinder 10 more compact. Specifically, in conjunction with Figure 8 and Figure 9As an example, the inner cylinder 20 also includes a first splicing side connecting channel 20f and a second splicing side connecting channel 20g, which are spliced ​​together by the first splicing portion 20a and the second splicing portion 20b. The first splicing side connecting channel 20f connects the splicing receiving cavity 20c and the first splicing groove 20d, and the second splicing side connecting channel 20g connects the splicing receiving cavity 20c and the second splicing groove 20g. The infrared light emitted by the infrared light-emitting module 30 can be emitted through the first splicing side connecting channel 20f and the second splicing side connecting channel 20g to further improve the light-emitting surface of the inner cylinder 20, so the infrared effect is more uniform.

[0044] Combination Figures 1 to 4 As an example, the side wall 11 of the outer cylinder 10 is provided with a second comb tooth body 70 opposite to the first heating element 50 in the radial direction of the first comb tooth 40. The second comb tooth body 70 also protrudes outward from the side wall 11 of the outer cylinder 10. Therefore, the second comb tooth body 70 is used to compensate for the position on the side wall 11 of the outer cylinder 10 where the first comb tooth 40 cannot pass through due to the obstruction of the first heating element 50, thereby increasing the combing angle range. Specifically, in Figures 1 to 4 As an example, the outer cylinder 10 has an insert cavity 16 on its side wall 11, which is separated from the first assembly cavity 141. The insert cavity 16 also corresponds to the first assembly cavity 141 in the radial direction of the first comb teeth 40, and the insert cavity 16 also penetrates the end face 17 and the side face 18 of the outer cylinder 10. The second comb tooth body 70 includes an insert base 71 and a plurality of second comb teeth 72 arranged in an array on the insert base 71 and protruding outward from the side wall 11 of the outer cylinder 10, so as to improve the combing effect by means of the second comb teeth 72. The insert body 71 can be in a direction parallel to the direction in which the insert cavity 16 penetrates the end face 17 of the outer cylinder 10 (e.g., Figure 4 The mounting base 71 is installed in the mounting cavity 16 in a direction from front to back or from back to front to improve the ease of assembly of the mounting base 71 to the outer cylinder 10.

[0045] Compared with the prior art, by using the inner cylinder 20 which includes a first splicing portion 20a and a second splicing portion 20b spliced ​​together along the radial direction of the first comb teeth 40, and a splicing receiving cavity 20c formed by the first splicing portion 20a and the second splicing portion 20b, the infrared light-emitting module 30 is quickly and accurately installed onto one of the first splicing portion 20a and the second splicing portion 20b from the radial direction of the first comb teeth 40, and then the other of the first splicing portion 20a and the second splicing portion 20b is spliced ​​together in the radial direction. This improves the convenience and reliability of assembling the infrared light-emitting module 30 into the inner cylinder 20, and eliminates wear.

[0046] The above-disclosed examples are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
