[0018] Figure 5 A schematic diagram of another embodiment of the heating assembly of this utility model; Detailed Implementation

[0019] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, it should be understood that the drawings are only used to illustrate the present invention and do not constitute a limitation on the present invention.

[0020] Figure 1 This is a hair dryer 10 according to one embodiment of the present invention. It includes an air inlet 102 and an air outlet 101. An airflow generator 103 draws air from the fan inlet 102 into the hair dryer body. It is understood that the airflow generator can be a fan or any other component that allows air to flow from the air inlet 102 to the air outlet 101.

[0021] The heating assembly 104 is used to heat the airflow entering the main body of the blower from the air inlet, and the heated airflow is discharged from the blower through the air outlet 101. The heating assembly 104 includes a mica heater 105, which includes one or more integrally formed mica heating plates. The mica heating plates are integrally formed from two layers of mica material plates and a heating material sandwiched between them.

[0022] It is understandable that in a hair dryer, depending on the required power, the mica heater can consist of one or more mica heating plates, which can be annular, sheet-like, or a combination of annular and sheet-like.

[0023] Although mica sheets are widely used in hair dryers, they are only used as support frames to support other components, such as the heating element.

[0024] The mica heater is a novel heating element. It uses mica as a high-temperature resistant insulating material to encapsulate the heating material, which is then integrally molded under high pressure to form a mica heating sheet with the heating material sandwiched between two layers of mica sheets. It is understood that the heating material according to this invention can be sandwiched between two layers of mica sheets in any way. For example, a metallic heating material can be printed onto the mica sheet to form the sandwiched heating material, and it can be printed in different widths and shapes.

[0025] The advantages of mica heaters include high operating temperatures, up to 1000 degrees Celsius. They are also excellent electrical insulators, meaning they do not conduct electricity when in contact with other conductive components. Therefore, applying mica heaters in hair dryers is advantageous. For example, due to their insulating properties, they can be more tightly packed inside the hair dryer body and among other components, effectively utilizing the internal space, producing more even hot air, and facilitating the design and manufacture of smaller hair dryers. Furthermore, their high-temperature resistance improves the safety and lifespan of the hair dryer and reduces the failure rate.

[0026] Figure 2 The diagram illustrates the specific structure of a one-piece molded mica heating plate. 201 and 202 are two layers of mica material sheets, and 203 is a metal heating material sandwiched between them. This could be a heating resistance wire typically used for heating, or a heating material printed onto the mica material sheets using a method similar to a printed circuit board. The heating material can be printed in any shape and width, or even completely fill the space between the two mica sheets.

[0027] Figure 3 This is a schematic diagram of one embodiment of the heating assembly of this utility model. As shown, the heating assembly 304 includes a mica heater 305 configured in a ring structure. This ring-shaped thin plate is made of an integrally formed mica heating thin plate consisting of two layers of mica thin plates with heating material sandwiched in between. When placed in a blower, the axial direction of the ring-shaped thin plate structure is aligned with the airflow direction to facilitate airflow. The dashed box in the figure shows the heating material sandwiched in the middle after the outer layer of mica material has been removed. One or more parallel-placed ring-shaped mica heating thin plates can be provided as needed.

[0028] Figure 4 This is a schematic diagram of another embodiment of the heating assembly of this utility model. As shown, the heating assembly 404 includes a mica heater 405, which is configured as a multi-layer annular structure formed by multiple annular mica heating plates 406 of different sizes, wherein the axial direction of each annular mica heating plate is aligned with the airflow direction. The multi-layer annular structure can be configured as follows: Figure 4 The coaxial, multi-layered ring structure shown is nested in order of size.

[0029] According to one embodiment of this utility model, the annular structure can be one or more of the following shapes: circular, elliptical, polygonal (e.g., rectangular). The annular structure can also be one or more of the following shapes: cylindrical, truncated conical. These shapes can be regular and symmetrical; or they can be irregular and asymmetrical.

[0030] Figure 5This is a schematic diagram of another embodiment of the heating assembly of this utility model. As shown, the heating assembly 504 includes a mica heater 505, which is configured as a support structure formed by the intersection of multiple thin plates. One or more of the thin plates are sheet-like mica heating plates 506. Preferably, the support structure can be entirely formed by the cross-connection of the mica heating plates 506, or only one or several of the thin plates can be configured as mica heating plates 506.

[0031] Furthermore, such as Figure 5 As shown, the heating assembly 504 may also include a heating resistance wire 507, which is wound around the mica heater 505. Figure 5 The cross-bracing structure is a common support structure in hair dryers, also known as a fishbone structure. However, existing fishbone structures are made of simple mica material, serving only to support the heating resistance wire and provide insulation. This invention replaces one or more of the thin plates with mica heating plates 506, resulting in higher air heating efficiency. This optimizes the hair dryer's structure, effectively utilizes the internal space, produces more uniform hot air, and allows for the design of a more compact hair dryer.

[0032] Understandably, a mica heater can be formed from multiple mica heating sheets in a combination of sheet and ring shapes. Although only Figure 5 This demonstrates the addition of an additional heating resistance wire to the support structure. Figure 3 and Figure 4 Additional heating resistance wires can also be added to the ring-shaped mica heater. Heating resistance wires can be wound separately on each ring, or heating wires can be wound only on the outer ring of the mica heating plate.

[0033] Although the present invention has been described in detail with reference to preferred embodiments, it should be understood that such detailed description is for illustrative purposes only and does not constitute a limitation thereof. The scope of the present invention is determined by the technical solutions defined in the claims.
