The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0028] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiments of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0029] like Figure 1-4 The example shown is an embodiment provided by the utility model.

[0030] The embodiment of the utility model provides a welding positioning structure of a hair dryer, including: a circuit main board 10 and a positioning frame 20, the circuit main board 10 is provided with a plurality of welding points 11, wiring holes 12 and positioning holes 13, each welding point 11 corresponds to a specific circuit connection point on the circuit main board 10, the wiring holes 12 are respectively arranged on the welding points 11 and penetrate the circuit main board 10, and can allow wires to pass through, the positioning holes 13 are dispersedly arranged on the circuit main board 10, at least two positioning holes 13 are arranged, and the position of the positioning holes 13 can be set according to the blank area on the circuit main board 10, generally set at the edge area of ​​the circuit main board 10. The positioning frame 20 is annular, and its outer contour is adapted to the outer contour of the circuit main board 10. The positioning frame 20 is connected to the component surface of the circuit main board 10. The positioning frame 20 surrounds the periphery of the components on the circuit main board 10, which can not only save installation space, but also protect the components on the circuit main board 10 to a certain extent. A plurality of wiring tubes 21 and positioning columns 22 are arranged on the positioning frame 20. The positions of the wiring tubes 21 correspond one-to-one to the positions of the wiring holes 12, and the positioning columns 22 are connected one-to-one with the positioning holes 13, so as to allow the ends of the wires to be inserted into the wiring holes 12 through the wiring tubes 21 and connected to the solder joints 11. During installation, it is only necessary to first align the positioning column 22 with the positioning hole 13, and the wiring tube 21 can be accurately connected to the wiring hole 12. Then the wire is passed through the wiring tube 21 and out of the wiring hole 12, so that the end of the wire is just within the range of the welding point 11. In this way, all wires that need to be welded can be pre-aligned with the corresponding welding points 11, which is convenient for the subsequent welding to be performed uniformly using semi-automatic or automatic welding equipment, which can not only improve the welding efficiency, but also reduce the defective rate of manually welded products.

[0031] Furthermore, an internal thread column 23 is provided on one side of the positioning column 22, and a connecting hole 14 is provided on one side of the positioning hole 13.

[0032] Furthermore, the length of the positioning column 22 is greater than the length of the wiring tube 21, and the positioning column 22 can be connected to the positioning hole 13 in advance, so that the wiring tube 21 is aligned with the wiring hole 12. The length of the wiring tube 21 is equal to the length of the internal thread column 23, so that after the internal thread column 23 is connected and fixed to the connecting hole 14 by screws, the end of the wiring tube 21 can be tightly fitted with the circuit board 10 and aligned with the wiring hole 12.

[0033] Furthermore, the inner diameter of the wiring tube 21 is adapted to the outer diameter of the wire, so that the distance between the end of the wire and the welding point 11 is closer, which can reduce the situation of cold welding. In addition, the inner diameter of the outlet end of the wiring tube 21 is smaller than the inner diameter of the inlet end, which facilitates the wire to pass through the wiring tube 21 and improves the threading efficiency.

[0034] The utility model also proposes: a hair dryer, including a hair dryer 30, a handle 40 and a welding positioning structure of the hair dryer, the handle 40 is connected to the side wall of the hair dryer 30, the circuit main board 10 and the positioning frame 20 are installed in the hair dryer 30, the circuit main board 10 is close to the rear end of the hair dryer 30, and in addition, the handle 40 is a hollow structure, and a hair drying component (not shown in the drawings), such as a motor and a fan, is arranged inside it. The handle 40 is connected to the hair dryer 30, and the wind blown out by the hair drying component can be blown out from the front end of the hair dryer 30 along the handle 40 and the wind duct in the hair dryer 30.

[0035] Specifically, a heating component 31 is provided in the hair dryer 30, and the heating component 31 is close to the front end of the hair dryer 30. When the wind blown out by the hair dryer component passes through the heating component 31, it will be heated, thereby blowing out hot air. The heating component 31 includes a heating wire 311, an annular mounting frame 312 and a plurality of supporting partitions 313. The mounting frame 312 is connected to the inner wall of the hair dryer 30, and the supporting partitions 313 are distributed along the circumference of the mounting frame 312.
