Description

Hair dryer for drying hair Technical Field The present utility model relates to hair dryers for drying hair, and more particularly to heaters for hair dryers. Background Mica flakes are widely used as a support for the heater wire of a hair dryer because of their high electrical and thermal insulation properties. Disclosure of utility model The present utility model provides a hair dryer for drying hair, comprising: An air inlet and an air outlet, the air inlet allowing air flow to enter the blower; a heating assembly for heating the air flow entering from the air inlet; The heated air flow is discharged out of the blower through the air outlet; Wherein the heating assembly comprises a mica heater comprising an integrally formed mica heating sheet integrally formed from two layers of cloud base material sheet and a heat generating material sandwiched therebetween. The blower of the present utility model further includes an air flow generator for sucking air flow from the air inlet and discharging air flow from the air outlet. Alternatively, the mica heater is provided in an annular configuration, wherein the axial direction of the annular configuration coincides with the direction of the air flow. Alternatively, the mica heater is provided as a multi-layered annular structure formed of a plurality of annular mica heating plates of different sizes, wherein the axial direction of each annular mica heating plate coincides with the direction of the air flow. Wherein the annular structure is one or more of cylindrical, frustoconical. Optionally, the mica heater is configured as a cross-brace structure comprising at least one mica heating sheet. Optionally, the heating assembly further comprises a heat-generating resistive wire wound around the mica heater. Drawings Figure 1 schematically illustrates a schematic diagram of a blower according to one embodiment of the utility model; FIG. 2 schematically shows a specific construction of an integrally formed mica heating sheet; FIG. 3 is a schematic view of one embodiment of a heating assembly of the present utility model; FIG. 4 is a schematic view of another embodiment of a heating assembly of the present utility model; FIG. 5 is a schematic view of yet another embodiment of the heating assembly of the present utility model; Detailed Description Specific embodiments of the utility model will be described in detail below with reference to the drawings, but it should be understood that the drawings are for illustration only and are not to be construed as limiting the utility model. Fig. 1 is a blower 10 for drying hair according to one embodiment of the present utility model. Including an air inlet 102 and an air outlet 101. The air flow generator 103 draws air from the fan inlet 102 into the blower body. It will be appreciated that the airflow generator may be a fan or any other component that enables air to flow from the air inlet 102 to the air outlet 101. The heating assembly 104 is used to heat the air flow entering the blower body from the air inlet, and the heated air flow exits the blower through the air outlet 101. The heating assembly 104 includes a mica heater 105, and the mica heater 105 includes one or more integrally formed mica heating sheets integrally formed from two cloud base material sheets and a heat generating material sandwiched therebetween. It will be appreciated that in a blower, depending on the power required, the mica heater may be formed of one or more mica heating sheets, either annular, or sheet, or a combination of annular and sheet. Although mica sheets are widely used in blowers, they are used only as a support frame to support other components, such as a heater. The mica heater is a novel heating element, the mica is used as a high-temperature resistant insulating material to wrap the heating material, and the mica heating sheet is formed by integrally forming the mica sheet by high-pressure pressing, wherein the heating material is clamped between the mica sheets. It will be appreciated that the heat generating material according to the utility model may be sandwiched between two layers of mica sheets in any manner. For example, a metallic heat generating material may be printed on a mica sheet to form a heat generating material sandwiched therebetween, and may be printed in different widths and shapes. The mica heater has the advantage of high working temperature which can reach 1000 ℃. It is also a good electrical insulator so that it does not conduct electricity when other conducting elements are in contact with it. Therefore, the use of a mica heater in a blower is advantageous. For example, due to the insulation of the mica heater, the mica heater can be arranged more closely inside the blower main body and between other components, the space inside the blower can be effectively utilized, more uniform hot air is blown out, and the design and manufacture of a smaller blower are facilitated. Meanwhile, due to the high temperatu
