Abstract
Description
Technical Field
[0001] This invention relates to the field of hair dryer heating element technology, specifically to a compact double-layer heating element with a temperature control module. Background Technology
[0002] Existing hair dryer heating elements typically consist of a frame, heating wire, and a temperature control module. The frame includes multiple circumferentially distributed sheet-like heat-resistant insulators, with multiple turns of heating wire wound around its outer perimeter. To increase the length of the heating wire on a frame of a given size, some heating elements use a wavy shape for the heating wire. However, the wavy heating wire occupies space between the sheet-like heat-resistant insulators on the frame, leaving insufficient space for installing the temperature control module. This forces the temperature control module to be installed independently of the frame, making the transportation, maintenance, and installation of the heating element inconvenient. Summary of the Invention
[0003] In view of the shortcomings of the prior art, the present invention aims to provide a compact double-layer heating element with a temperature control module.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: A compact, double-layered heating element with a temperature control module includes a frame, heating wires wound around the frame, and a temperature control module. The frame includes multiple sheet-like heat-resistant insulators distributed circumferentially. Each sheet-like heat-resistant insulator comprises long sheet-like insulators and short sheet-like heat-resistant insulators, with the radial extension length of the long sheet-like insulators greater than that of the short sheet-like insulators, and the long and short sheet-like insulators are alternately arranged. The heating wire includes an outer heating wire and an inner heating wire. The outer heating wire is wavyly wound around the outer periphery of each long sheet-like heat-resistant insulator, and the inner heating wire is wavyly wound around the outer periphery of each short sheet-like heat-resistant insulator. The temperature control module is fixed to one side of one of the long sheet-like heat-resistant insulators, and the portion of the outer heating wire corresponding to the position of the temperature control module is linear.
[0005] Furthermore, multiple turns of outer heating wire are wound from top to bottom around the outer periphery of each long sheet-shaped heat-resistant insulator, and multiple turns of inner heating wire are wound from top to bottom around the outer periphery of each short sheet-shaped heat-resistant insulator. Each turn of outer heating wire and each turn of inner heating wire are wavy, and the portion of each turn of outer heating wire corresponding to the location of the temperature control module is straight.
[0006] Furthermore, each of the long and short heat-resistant insulators has multiple recesses along its outer periphery from top to bottom. Each recess on the outer periphery of the long heat-resistant insulator corresponds to a specific one, and each recess on the outer periphery of the short heat-resistant insulator corresponds to a specific one. The outer heating wires of each ring are fixedly embedded in the corresponding recesses on the outer periphery of each long heat-resistant insulator, and the inner heating wires of each ring are fixedly embedded in the corresponding recesses on the outer periphery of each short heat-resistant insulator.
[0007] Furthermore, each long sheet-shaped heat-resistant insulator has through holes, and the inner heating wire passes through the through holes on each long sheet-shaped heat-resistant insulator and is wound around the outer periphery of each short sheet-shaped heat-resistant insulator.
[0008] The beneficial effects of this invention are as follows: 1. This invention, through the combination of long sheet-shaped heat-resistant insulators and short sheet-shaped heat-resistant insulators, adds a layer of heating wire within the limited volume and space of the heating element, thereby increasing the heating capacity of the heating element.
[0009] 2. This invention sets one section of the outer heating wire to be straight, leaving an installation space for the temperature control module on the side of the long sheet-shaped heat-resistant insulator. This allows the temperature control module to be directly fixed to one side of one of the long sheet-shaped heat-resistant insulators, thus enabling the installation of the temperature control module on the heating element with densely wavy heating wires.

[0011] The present invention will be further described below with reference to the accompanying drawings. It should be noted that this embodiment is based on the present technical solution and provides detailed implementation methods and specific operation processes, but the protection scope of the present invention is not limited to this embodiment.
[0012] This embodiment provides a compact double-layer heating element with a temperature control module, such as... Figure 1-2As shown, the device includes a frame 1, heating wires wound around the frame 1, and a temperature control module 2. The frame 1 includes multiple sheet-like heat-resistant insulators distributed circumferentially. The sheet-like heat-resistant insulators include long sheet-like heat-resistant insulators 3 and short sheet-like heat-resistant insulators 4. The radial extension length of the long sheet-like heat-resistant insulators 3 is greater than the radial extension length of the short sheet-like heat-resistant insulators 4, and the long sheet-like heat-resistant insulators 3 and short sheet-like heat-resistant insulators 4 are alternately arranged. The heating wire includes an outer heating wire 5 and an inner heating wire 6. The outer heating wire 5 is wavyly wound around the outer periphery of each long sheet-like heat-resistant insulator 3, and the inner heating wire 6 is wavyly wound around the outer periphery of each short sheet-like heat-resistant insulator 4. The temperature control module 2 is fixed to one side of one of the long sheet-like heat-resistant insulators 3, and the portion of the outer heating wire 5 corresponding to the position of the temperature control module 2 is straight.
[0013] In the aforementioned double-layer heating element, the combination of long and short heat-resistant insulators adds a heating wire layer within the limited volume and space of the heating element, thereby increasing its heat output. While ensuring sufficient heat output, by making one section of the outer heating wire straight, an installation space is provided on the side of the long heat-resistant insulator for the temperature control module. This allows the temperature control module to be directly fixed to one side of one of the long heat-resistant insulators, enabling the installation of the temperature control module on the heating element with its densely packed, wavy heating wires. This embodiment of the double-layer heating element balances both heat output and the integrated installation of the temperature control module.
[0014] It should be noted that, in order to make Figure 1 The various parts are clearer. Figure 1 The structure of the inner heating wire is omitted.
[0015] In this embodiment, multiple outer heating wires 5 are wound from top to bottom around the outer periphery of each long sheet-shaped heat-resistant insulator 3, and multiple inner heating wires 6 are wound from top to bottom around the outer periphery of each short sheet-shaped heat-resistant insulator. Each outer heating wire 5 and each inner heating wire 6 is wavy, and the portion of each outer heating wire 5 corresponding to the location of the temperature control module 2 is straight.
[0016] Furthermore, in this embodiment, each of the long sheet-shaped heat-resistant insulators 3 and the short sheet-shaped heat-resistant insulators 4 has multiple recesses from top to bottom on its outer peripheral edge. Each recess on the outer peripheral edge of each long sheet-shaped heat-resistant insulator 3 corresponds to one another, and each recess on the outer peripheral edge of each short sheet-shaped heat-resistant insulator 4 corresponds to one another. The outer heating wires 5 of each ring are fixedly embedded in the corresponding recesses on the outer peripheral edge of each long sheet-shaped heat-resistant insulator 3, and the inner heating wires 6 of each ring are fixedly embedded in the corresponding recesses on the outer peripheral edge of each short sheet-shaped heat-resistant insulator 4.
[0017] In this embodiment, each long sheet-shaped heat-resistant insulator 3 has a through hole 31, and the inner heating wire 6 passes through the through hole 31 on each long sheet-shaped heat-resistant insulator 3 and is wound around the outer periphery of each short sheet-shaped heat-resistant insulator 4.
[0018] For those skilled in the art, various corresponding changes and modifications can be made based on the above technical solutions and concepts, and all such changes and modifications should be included within the protection scope of the claims of this invention.
