Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application pertains. The terms used herein in the specification of this application are for the purpose of describing specific embodiments only and are not intended to limit this application.

[0030] Most hair dryers on the market consist of a barrel and a handle. There's usually a large gap between the barrel's components, which results in a bulky and relatively thick barrel. For those who need to store the hair dryer in a small space, such as when traveling, the large size can be a hassle to carry around.

[0031] In view of this, the utility model provides a miniaturized hair dryer. Figure 1-6 For an embodiment of the miniaturized hair dryer provided by the present invention, please refer to Figure 1-6 The hair dryer 100 includes a hair dryer 1 , a shell 2 and a handle 3 .

[0032] Specifically, the air duct 1 is in the shape of a long cylinder, having a central axis and a cylinder wall formed roughly around the central axis. An air inlet 1a and an air outlet 1b are respectively provided at both ends of the air duct 1. From the air inlet 1a to the air outlet 1b, a motor 11, a circuit board 12 and a heater 13 are sequentially provided inside the air duct 1. The motor 11 is equipped with fan blades to provide power to generate negative pressure and draw air from the air inlet 1a; the circuit board 12 is electrically connected to the motor 11 and the heater 13 respectively to control their operation. The cylindrical shell 2 is fixedly mounted on the outer periphery of the air duct 1 to protect the air duct 1. The handle 3 is rotatably connected to the shell 2 for easy storage. The rotatable connection can be a hinged connection, which will not be described in detail here.

[0033] Among them, the circular cross-sectional radius of the mounting section of the motor 11 of the air duct 1 is smaller than the circular cross-sectional radius of the mounting section of the circuit board 12 and the heater 13, so that the circuit board 12 can be conveniently set, and the circuit board 12 is set parallel to the axis of the air duct 1, and the circular cross-sectional areas of the mounting sections of the circuit board 12 and the motor 11 are tangent, so that they will not block the flow of air.

[0034] In the technical solution of the present invention, by optimizing the structure of the wind duct 1, designing the cross-section of the wind duct 1 corresponding to the motor 11 and the circuit board 12, and arranging the circuit board 12 and the axis of the wind duct 1 parallel and tangent to the cross-section of the wind duct 1 corresponding to the motor 11, the internal space of the wind duct 1 is saved, the structure is compact and will not interfere with each other, the volume of the wind duct 1 is reduced, and the cylinder body is also relatively thin.

[0035] To further reduce the cross-sectional area of ​​the barrel, see Figure 2 and Figure 3 In one embodiment of the present invention, the rotating shaft of motor 11 is parallel to the central axis of hair duct 1 and offset relative to the central axis of hair duct 1, specifically, offset away from circuit board 12. That is, circuit board 12 and motor 11 are mounted on opposite sides of hair duct 1 without interfering with each other. This spatial arrangement reduces the cross-section of hair duct 1, making hair dryer 100 more compact.

[0036] See also Figure 3 and Figure 6In one embodiment of the present invention, a negative ion generator 14 is installed outside the wall of the air duct 1, and the installation position corresponds to the installation section of the motor 11, which makes full use of the space outside the air duct 1 and is wrapped in the shell. It should be noted that the negative ion generator 14 is a device for generating negative air ions. After the input DC or AC power is processed by the circuit, it is upgraded to AC high voltage through pulse circuits, overvoltage limiting, high and low voltage isolation and other lines, and then rectified and filtered by special grade electronic materials to obtain pure DC negative high voltage. The DC negative high voltage is connected to a release tip made of metal or carbon elements, and the DC high voltage at the tip is used to generate high corona, which releases a large number of electrons (e - ) and will be immediately captured by oxygen molecules (O2) in the air to generate negative air ions.

[0037] Furthermore, in order to allow the electrons generated by the negative ion generator 14 to be captured by oxygen molecules in the air, please refer to Figure 6 In one embodiment of the present invention, the electrical connection line 141 of the negative ion generator 14 extends along the wall of the wind tube 1 to the air outlet 1b, and the electrical connection line 141 is connected by a conductive wire and a copper wire.

[0038] In order to better dissipate heat from the heating element 121 of the circuit board 12, please refer to Figure 2 and Figure 3 In one embodiment of the present invention, the heating element 121 of the circuit board 12 is located on one side of the circuit board and is correspondingly disposed in the air duct of the air duct 1. When air flows in the air duct 1, it dissipates heat from the heating element 121, which absorbs heat and is further heated by the heater 13 before being blown out.

[0039] To facilitate connecting the wires, see Figure 6 In one embodiment of the present invention, the hair dryer 1 is provided with an opening 1c at the mounting section of the circuit board 12 for extending the wires of the circuit board 12. After extending from the opening 1c, the wires extend between the hair dryer 1 and the housing, and extend into the handle 3, extending from the end of the handle 3.

[0040] For easier handling, see Figure 2 and Figure 3 In one embodiment of the present invention, the heavier motor 11 is arranged near the connection between the handle 3 and the hair dryer 1, so that the center of gravity is close to the handle 3.

[0041] To make the handle 3 and the shape of the hair dryer 1 match, please refer to Figure 1 In one embodiment of the present invention, the handle 3 is cylindrical, preferably a long straight cylinder.

[0042] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0043] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art could make various modifications and improvements without departing from the spirit of the present application, all of which fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
