[0030] 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.

[0031] like Figure 1-4 The example shown is an embodiment provided by the utility model.

[0032] The utility model provides a hair dryer, comprising: a hair dryer 10, a handle 20, a tail light assembly 30 and a circuit main board 40, wherein the handle 20 is arranged on the side wall of the hair dryer 10, the circuit main board 40 is installed in the hair dryer 10 and is electrically connected to the tail light assembly 30; the tail light assembly 30 comprises a mounting seat 31, a light guide ring 32 and a connecting cylinder 33, the mounting seat 31 is sleeved on the rear end of the hair dryer 10, the connecting cylinder 33 is arranged at the inner end of the mounting seat 31 and is connected to the front end of the hair dryer 10, and the light guide ring 32 is arranged at the outer end of the mounting seat 31; the circuit main board 40 is annular, the circuit main board 40 is sleeved on the connecting cylinder 33 and is close to the mounting seat 31; a plurality of LEs are arranged on the circuit main board 40 along the circumferential direction of the connecting cylinder 33 D lamp 41. Generally speaking, LED lamps 41 are equidistantly distributed. LED lamps 41 are RGB lamp beads that can emit lights of multiple colors. In specific implementation, each LED lamp 41 can emit light of only one color, or each LED lamp 41 can emit light of multiple colors. The circuit mainboard 40 can control the operation of the LED lamp 41 or the switching of the light color and the flashing effect. At the same time, a plurality of light-transmitting holes 311 are arranged around the circumferential direction of the connecting tube 33 on the mounting seat 31. The positions of the LED lamps 41 and the light-transmitting holes 311 correspond one to one. The light can be irradiated onto the light guide ring 32 through the light-transmitting holes 311. The light guide ring 32 is a light-guiding material, and the light can be transmitted along the light guide ring 32. After adopting the above-mentioned hair dryer, the annular circuit main board 40 is sleeved on the connecting tube 33, so that the LED lamp 41 surrounds the connecting tube 33 and corresponds one by one with the light-transmitting hole 311 opened on the connecting seat 11. This can allow the light of the LED lamp 41 to form a lamp ring through the light guide ring 32 to ensure the lighting effect of the hair dryer, and reduce the area of ​​the circuit main board 40, thereby improving the utilization rate of the circuit board and helping to reduce production costs.

[0033] Furthermore, a plurality of positioning strips 331 are provided on the outer wall of the connecting tube 33, and a plurality of positioning notches 42 are provided on the inner edge of the circuit main board 40.

The inner end of the light guide tube 35 is sleeved with the inner ring of the light guide ring 32. The light guide tube 35 is also made of light-guiding material, which can further guide the light transmitted by the light guide ring 32 outward and produce a light shape that is the same as the shape of the light guide tube 35, so that the lighting effect of the hair dryer is better.

[0036] Specifically, a connecting seat 11 is provided at the front end of the hair dryer 10, and a mounting tube 12 is provided at the inner end of the connecting seat 11. The side wall of the connecting seat 11 is connected to the inner wall of the hair dryer 10, and the inner end of the mounting tube 12 is docked with the inner end of the connecting tube 33, thereby fixing the taillight assembly 30 at the rear end of the hair dryer 10 and preventing it from falling off easily.

[0037] Specifically, a heating wire 13 and a mounting frame 14 are arranged in the hair dryer 10. The mounting frame 14 is arranged around the outside of the mounting barrel 12 and close to the connecting seat 11. The heating wire 13 is coiled on the mounting frame 14. In addition, in order to allow the heating wire 13 to contact the air to a greater extent, a plurality of supporting baffles 15 are distributed around the outer wall of the mounting frame 14, and the heating wire 13 is coiled outside the supporting baffles 15.

[0038] Furthermore, an isolation frame 16 is also provided in the hair dryer 10, one end of the isolation frame 16 is connected to the mounting frame 14, and the other end of the isolation frame 16 is connected to the circuit main board 40, so that the circuit main board 40 and the heating wire 13 are relatively isolated and fixed in the hair dryer 10.
