[0033] like Figure 1 , Figure 2 As shown, the music hair dryer in this embodiment mainly includes: a blowing housing 100, a music playing circuit board 200 and a speaker 210. An installation cavity 111 is provided in the blowing housing 100, an air outlet 112 is provided on one side of the installation cavity 111, a back cover 130 is provided on the end of the installation cavity 111 opposite to the air outlet 112, the music playing circuit board 200 is provided on the side of the installation cavity 111 close to the back cover 130, the speaker 210 is located in the installation cavity 111, and is provided on the side of the music playing circuit board 200 facing the back cover 130, and the sound-emitting side of the speaker 210 faces the back cover 130. The music playing circuit board 200 is provided with a music playing circuit, an audio playing chip and a data storage device, and audio playing can be realized when electrically connected to the speaker 210. The audio playing circuit and the chip belong to the prior art and will not be described in detail.

[0034] like Figure 1 , Figure 2As shown, in the specific structure, the present hair dryer housing 100 is similar to a conventional hair dryer housing, and the hair dryer housing 100 specifically includes a hair dryer head housing 110 and a hair dryer handle housing 120. For the convenience of structural description, the extension direction of the hair dryer head housing 110 is a first direction, which can be a front-to-back direction, and the air outlet 112 is arranged on the front side of the hair dryer head housing 110 to form an air outlet side, and the back cover 130 is arranged on the rear side of the hair dryer head housing 110 opposite to the air outlet 112, and the back cover 130 seals the hair dryer head housing 110 on the rear side. In this way, the hair dryer blows toward the front side when in use; the extension direction of the hair dryer handle housing 120 is a second direction, which can be an up-down direction, and the hair dryer handle housing 120 is connected to the inside of the hair dryer head housing 110. In addition to being arranged vertically, the first direction and the second direction can also be arranged at a certain acute angle (obtuse angle). The installation cavity 111 is arranged inside the hair dryer head housing 110, so it extends along the front-to-back direction. In addition, the hair dryer head shell 110 of this embodiment is cylindrical or has a circular cross section (a certain section in the front-to-back direction is cylindrical or similar to a cylindrical shape), so that the hair dryer head shell 110 has a central axis. The hair dryer handle shell 120 in this embodiment is provided with an air inlet channel 121 along the second direction, so the air inlet channel 121 can be provided along the up-down direction, and a plurality of air inlets 122 are provided on the outer wall of the lower end of the hair dryer handle shell 120, and the air inlets 122 are connected to the air inlet channel 121. A fan is provided in the air inlet channel 121, and under the action of the fan, air is allowed to enter the air inlet channel 121 from the air inlet 122 to form wind, and then blown into the hair dryer head shell 110, and blown forward through the air outlet 112.

[0035] like Figure 1 , Figure 2 As shown, in this embodiment, an air outlet 112 is arranged at the front end of the blowing housing 100, and a back cover 130 is arranged at the rear end, and the wind direction is to be transported from the bottom to the top and then blown out from the front air outlet 112, so as not to affect the structure at the rear end. The music playing circuit board 200 and the speaker 210 are arranged on the side close to the back cover 130, so that the sound-emitting side of the speaker 210 faces the back cover 130, so that the air outlet side and the sound-emitting side for blowing are located at opposite ends of the blowing housing 100, and the wind formed from bottom to top is directly blown out from the front air outlet 112 without entering the sound-emitting structure at the rear side, so that the air outlet side and the sound-emitting side can be separated, the air outlet 112 blows forward, and the speaker 210 emits sound toward the rear, thereby greatly reducing the risk of the played music sound being disturbed by the strong wind from the air outlet, and improving the sound-emitting effect of the speaker 210.

[0036] like Figure 1 , Figure 3As shown, further, the music playing circuit board 200 in this embodiment is fixedly connected to the back cover 130. During the assembly process of the hair dryer, the back cover 130 can be detachably connected to the rear end of the hair dryer housing 100 through the hook or ear 133 at the edge. After the music playing circuit board 200 is fixedly connected to the back cover 130, when assembling the hair dryer, the back cover 130 can be assembled to the rear end of the hair dryer housing 100 to complete the installation. This makes the assembly process simpler and more convenient, reduces the assembly difficulty, and improves the assembly efficiency.

[0037] Furthermore, in order to achieve the fixation of the music playing circuit board 200 and the back cover 130. A plurality of screw connection posts 131 are arranged on the side of the back cover 130 facing the installation inner cavity 111, and a limiting plate 132 is arranged on one side of at least one screw connection post 131. A through hole 201 corresponding to the screw connection post 131 is opened on the music playing circuit board 200, and a limiting groove 202 is arranged on at least one through hole 201. When assembling, the music playing circuit board 200 is fixed to the inner side of the back cover 130 by inserting screws through the plurality of through holes 201 and connecting to the corresponding screw connection posts 131. In order to prevent the music playing circuit board 200 from being deviated during the connection process, the limiting plate 132 is inserted into the limiting groove 202 shown during the assembly process. Through the positioning effect of the limiting plate 132 on the limiting groove 202, after inserting screws through the through hole 201 and connecting the screw connection post 131, the music playing circuit board 200 is accurately fixed at a predetermined position. In particular, the speaker 210 on the music playing circuit board 200 will not be offset.

[0038] like Figure 2 , Figure 3 , Figure 4 As shown, in this embodiment, only one side of the screw connection column 131 is provided with a limiting piece 132, and the limiting piece 132 protrudes from the top of the screw connection column 131, so as to facilitate insertion into the limiting groove 202 of the music playing circuit board 200. The limiting piece 132 is located on the side of the screw connection column 131 facing the central axis of the back cover 130, so the limiting groove 202 on the through hole 201 extends a predetermined length toward the center direction of the music playing circuit board 200. In this way, the limiting groove 202 is completely opened in the inner part of the music playing circuit board 200 toward the center, which has little effect on the structural strength of the music playing circuit board 200.

[0039] like Figure 2 , Figure 3 , Figure 4As shown, further, the speaker 210 in this embodiment is fixed on the music player circuit board 200. For example, the two are directly welded and fixed, or the speaker 210 is fixedly connected to the music player circuit board 200 through a fixing frame. The speaker 210 and the music player circuit board 200 are fixedly arranged so that the speaker 210 and the music player circuit board 200 form an integral audio player module, and the integral audio player module is installed on the back shell, which simplifies the installation process and improves the installation efficiency. One end of the connecting frame can be welded and fixed on the music player circuit board 200, and the other end can be welded on the speaker 210, so that the connecting frame can be used as a fixed structure while also transmitting signals, so the connecting frame can be a pad structure, etc.

[0040] like Figure 2 , Figure 3 , Figure 4 As shown, further, a positioning ring 134 is provided on the side of the back cover 130 in this embodiment facing the installation inner cavity 111, and the speaker 210 is embedded in the positioning ring 134. By providing the positioning ring 134, the speaker 210 can be fixed, and the speaker 210 will not shake during the use of the hair dryer. In addition, the inner wall of the positioning ring 134 cooperates with the outer wall of the speaker 210, so that the sound of the speaker 210 is emitted toward the back cover 130, and a sound outlet hole 135 is provided on the surface of the back cover 130, and the sound emitted by the speaker 210 is emitted through the sound outlet hole 135. In this way, due to the limitation of the positioning ring 134, the sound will not be dispersed into the interior of the hair dryer housing 100, thereby affecting the sound effect.

[0041] By using the matching mode of the limiting piece 132 and the limiting groove 202 , the speaker 210 can also be accurately assembled into the positioning ring 134 , thereby facilitating the assembly of the speaker 210 and the positioning ring 134 .

[0042] like Figure 3 , Figure 4 As shown, further, the music playing circuit board 200 in this embodiment is electrically connected to a Bluetooth communicator 220, which is used for wireless communication and receiving external audio to play sound through the speaker 210. The Bluetooth communicator 220 receives the audio signal of the external mobile terminal, such as a mobile phone, through wireless communication. Then, the audio signal is played through the speaker 210, thereby increasing the audio playing function and improving the practicality of the hair dryer.

[0043] In addition, the music playing circuit board 200 and the speaker 210 can also play various prompt sounds, such as air volume, temperature, mode status, etc.

[0044] like Figure 2As shown, further, a circle of indicator lights 230 is provided on the music playing circuit board 200 of this embodiment. The indicator lights 230 can be used to indicate the use status of the hair dryer, such as the current gear, the current blowing temperature, etc.; they can also be changed according to the rhythm of the music, making the hair dryer more fashionable and attractive to attract consumers.

[0045] like Figure 2 , Figure 4 , Figure 5 As shown, a display screen 240 is provided on the music playing circuit board 200 in this embodiment, and the display screen 240 is provided in an area surrounded by a circle of indicator lights 230. The display screen 240 is used to display images. Correspondingly, a light-transmitting panel 136 is provided on the back cover 130, and the light-transmitting panel 136 is located on the light-emitting side of the display screen 240 and the light-emitting side of the indicator lights 230.

[0046] like Figure 2 , Figure 4 , Figure 5 As shown, the light-transmitting panel 136 has the function of transmitting light from the inside of the back cover 130 to the outside, but not from the outside of the back shell to the inside, so that the user cannot see the internal structure of the back shell through the light-transmitting panel 136 from the outside, and the ugliness is concealed; while the internal display screen 240 can emit images for normal display. The light-transmitting panel 136 is located at the center of the back cover 130 and is set to be circular. An inclined surface 137 is formed around the light-transmitting panel 136 on the surface of the back cover 130, and the inclined surface 137 makes the light-transmitting panel 136 concave toward the front side. The light-transmitting panel 136 that moves inward toward the front side is closer to the display screen 240, so that the image of the display screen 240 is displayed more clearly through the light-transmitting panel 136.

[0047] like Figure 1 , Figure 2As shown, further, the installation cavity 111 in this embodiment is also provided with: a main circuit board 310 and a windshield tail rack 300. The main circuit board 310 is located on the side of the music playing circuit board 200 away from the back cover 130, and the windshield tail rack 300 is located on the side of the main circuit board 310 away from the music playing circuit board 200. The windshield tail rack 300 is connected to the main circuit board 310 to block the installation cavity 111 to separate the music playing circuit board 200 from the air outlet 112. In the specific structure, the circuit of the main circuit board 310 is used to realize the circuit control function of the hair dryer. The main circuit board 310 is connected to the windshield tail rack 300 to form a partition structure, and the installation cavity 111 is divided by the partition structure to form an air outlet part located at the front side and an installation space part located at the rear side. The front air outlet is connected to the air inlet channel 121, while the rear installation space is separated from the air inlet channel 121, so that the wind in the lower air inlet channel 121 can only be transported from the front air outlet and blown out from the front air outlet 112. The wind cannot enter the rear installation space, so it will not affect the sound of the speaker 210 in this area, thereby improving the sound playback quality.

[0048] like Figure 3 , Figure 4 As shown, further, a plug connector 250 is fixed to the side of the music playing circuit board 200 in this embodiment away from the back cover 130, and the plug connector 250 is electrically connected to the main circuit board 310 through a detachable connecting cable. The plug connector 250 can be quickly disassembled and connected with the connecting cable, thereby facilitating circuit connection.

[0049] like Figure 1 , Figure 3 , Figure 4 As shown, the main circuit board 310 and the music playing circuit board 200 are separated by a predetermined distance to form an installation gap, and the plug connector 250 is located in the installation gap. Setting the installation gap can provide more component installation positions, for example, the Bluetooth communicator 220 can also be set on the back of the music playing circuit board 200, so as to be located in the case gap, so that the structure is more optimized.
