[0001] This utility model relates to the field of hair dryer technology, and in particular to a heating structure for a hair dryer. Background Technology
[0002] In existing hair dryer technology, the heating element typically consists of multiple mica sheets, which are assembled using connectors. This design makes the assembly process complex and cumbersome, requiring multiple steps to connect and secure the mica sheets, significantly reducing assembly efficiency. Furthermore, the use of connectors not only increases the variety and number of components but also raises the production costs of individual components and the overall assembly cost. This, to some extent, affects the production efficiency and market competitiveness of hair dryers and imposes a high cost burden on manufacturers. Therefore, there is an urgent need for an improved heating structure to simplify the assembly process of the hair dryer heating element, reduce the number of components, lower production costs, and improve assembly efficiency. Utility Model Content

Each mica sheet includes two first inserts and one second insert. Both the first and second inserts are rectangular. The first insert has an axis of symmetry parallel to its long side, and the second insert has an axis of symmetry parallel to its long side and an axis of symmetry parallel to its short side. The axes of symmetry parallel to the long sides of the three mica sheets coincide, and the angles between the mica sheets are uniform. The two bases engage with the three mica sheets from both ends, with the short sides of the mica sheets embedded in the slots. The long sides of the mica sheets have evenly spaced grooves. A heating wire embedded in the grooves is arranged around the mica sheet, and a mica layer is provided on the outer side of the heating wire.
[0006] Preferably, the two first inserts are arranged in opposite directions.
[0007] Preferably, the first insert has a first slot at its center, one end of the first slot extends to a short side that passes through the first insert, and the other end of the first slot is close to the other short side of the first insert.
[0008] Preferably, the second insert has two second slots, each extending to one side to pass through the short side of the second insert, and the portion between the two second slots of the second insert passes through the first slot of the first insert.
[0009] Preferably, the first insert has a first slot on its short side and the second insert has a second slot on its short side, and the first slot and the second slot respectively engage with the slots on the side plate.

[0011] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:
[0012] This utility model relates to a heating structure for a hair dryer, comprising two interlocking bases and three mica sheets. Each base has a slot at one end. Each mica sheet includes two first inserts and one second insert. Both the first and second inserts are rectangular. The first insert has an axis of symmetry parallel to its long side, and the second insert has an axis of symmetry parallel to its long side and an axis of symmetry parallel to its short side. The axes of symmetry parallel to the long sides of the three mica sheets coincide, and the angles between the mica sheets are uniform. The two bases engage with the three mica sheets from both ends, with the short sides of the mica sheets embedded in the slots. The long sides of the mica sheets have evenly spaced grooves. A heating wire, embedded in the grooves, surrounds the mica sheet, and a mica layer is provided on the outer side of the heating wire. This utility model requires only one type of base and two types of mica sheets, reducing the variety of types, facilitating production, and reducing confusion. During installation, no extra effort is required to distinguish between them, preventing installation errors due to using the wrong parts, improving assembly efficiency, and making installation more efficient and stable.

[0023] As attached Figure 1 Appendix Figure 2 The diagram shows the heating structure of this utility model for a hair dryer, comprising two bases 3 interlocking as a whole and three mica sheets. One end of each base 3 has a groove 31. The mica sheets include two first inserts 1 and one second insert 2, as shown in the attached diagram. Figure 3 Appendix Figure 4 As shown, both the first insert 1 and the second insert 2 are rectangular. The first insert 1 has an axis of symmetry parallel to its long side, and the second insert 2 has an axis of symmetry parallel to its long side and an axis of symmetry parallel to its short side. The axes of symmetry parallel to the long sides of the three mica sheets coincide, and the angles between the mica sheets are uniform, forming a 60° angle between them. The two bases 3 engage with the three mica sheets from both ends, and the short sides of the mica sheets are embedded in the slots 31. Uniformly spaced grooves 4 are formed on the long sides of the mica sheets, as shown in the attached diagram. Figure 6 As shown, the heating wire 5 with embedded toothed grooves 4 surrounds the mica sheet, which makes the heat even. The outer side of the heating wire 5 is covered with a mica layer 6, which provides heat insulation and shock absorption, and absorbs the vibration and noise generated when the motor is running, thus improving the user experience of the hair dryer.
[0024] The first insert 1 has a first slot 11 at its center. One end of the first slot 11 extends to a short side that passes through the first insert 1, and the other end of the first slot 11 is close to the other short side of the first insert 1. The second insert 2 has two second slots 21, each extending to one side to pass through the short side of the second insert 2. The portion between the two second slots 21 of the second insert 2 passes through the first slot 11 of the first insert 1. The two first inserts 1 are installed in opposite directions.
[0025] The first insert 1 has a first slot 12 on its short side, and the second insert 2 has a second slot 22 on its short side. The first slot 12 and the second slot 22 respectively engage with the slots 31 on the side plate, making the connection stable. The base 3 includes a side plate that is connected end to end to form a hexagon, and the slots 31 are located on the side plate. The hexagonal shape of the base 3 ensures that the contact surfaces of the mica sheet and the base 3 are perpendicular to each other when they are inserted and connected. Compared with the circular structure of the base 3, the hexagonal base 3 makes the slots 31 less prone to deformation, less prone to skewing when connected with the mica sheet, and the connection is more stable, reliable, and less likely to loosen.
[0026] As attached Figure 5 As shown, during installation, firstly, a first insert 1 is connected to a base 3, with the first slot 11 on the first insert 1 facing away from the base 3. Next, a second insert 2 is connected to the base 3, with the second slot 21 of the second insert 2 avoiding the first insert 1. Then, another first insert 1 is connected to the base 3, with the installation direction of the second first insert 1 opposite to that of the first first insert 1, ensuring the three mica sheets are connected in an orderly manner without interference. Finally, another base 3 is connected to the three mica sheets, forming a stable and integrated whole with the two bases 3. This connection structure requires only one shape of base 3 and two shapes of mica sheets, reducing the variety, facilitating production, and preventing confusion. The shapes of the first insert 1 and the second insert 2 are clearly distinguishable, eliminating the need for extra effort to differentiate them during installation and preventing installation errors due to using the wrong parts. This makes installation more efficient and stable.
[0027] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
