[0036] In order to make the purpose, technical scheme and advantages of the present application clearer, the present application will be further described in detail below with reference to the drawings and embodiments.

[0037] Please refer to Figures 1 to 6 , the light assembly 20 of the hair styling device provided by the embodiment of the present application will be described. The light assembly 20 of the hair styling device comprises a main body part 10 and a light assembly 20.

[0038] The light assembly 20 comprises a first circuit board 21, a pressing plate 22, a sealing sheet 23 and a button housing 24, the first circuit board 21 is installed on the main body 10; the rear side of the first circuit board 21 is provided with a press switch and a lamp bead, the lamp bead is located on one side or both sides of the press switch; the pressing plate 22 is stacked on the rear side of the first circuit board 21, the sealing sheet 23 is stacked on the rear side of the pressing plate 22 and covers the press switch, and the button housing 24 is movably installed on the main body 10; when the button housing 24 is moved, it can abut against the sealing sheet 23 and make the sealing sheet 23 deformed to trigger the press switch.

[0039] Specifically, by stacking the pressing plate 22 and the sealing sheet 23 on the rear side of the first circuit board 21 in turn, when the button housing 24 is moved, the sealing sheet 23 can be deformed by triggering to trigger the press switch; since the sealing sheet 23 and the pressing plate 22 are a split structure, when the sealing sheet 23 is deformed, no gap is generated between the sealing sheet 23 and the pressing plate 22, thereby ensuring that the light of the lamp bead cannot be scattered from the gap to the end of the button housing 24, thereby solving the light leakage problem; not only can the visual effect of the user be improved, but also the case that the light exists light interference and interferes with the identification state can be prevented, thereby reducing the operation difficulty of the user.

[0040] In some embodiments of the present application, the pressing plate 22 is provided with a first hollow part 221 penetrating through the front and rear surfaces of the pressing plate 22; the press switch is located in the first hollow part 221 region, the sealing sheet 23 covers the first hollow part 221, and the size of the covering sheet is greater than that of the first hollow part 221. The rear side of the pressing plate 22 is provided with a protruding part 222 at the edge of the first hollow part 221, and the protruding part 222 can penetrate into the sealing sheet 23.

[0041] Preferably, the cross section of the protruding part 222 is a triangular structure, and the protruding part 222 is continuously and closely surrounded at the edge of the first hollow part 221 to form a closed ring structure without interruption. In this way, when the sealing sheet 23 covers the first hollow part 221, the protruding part 222 at the edge of the first hollow part 221 can penetrate into the sealing sheet 23, thereby improving the reliability of the sealing sheet 23 covering the first hollow part 221 and reducing the generation of gaps.

[0042] Specifically, the rear side of the pressing plate 22 is provided with a light shielding column, the light shielding column is located on one side or both sides of the first hollow part 221, and the front side of the pressing plate 22 is recessed with a light guide recess 225 at the position of the light shielding column; after the pressing plate 22 is stacked on the rear side of the first circuit board 21, the lamp bead is located in the light guide recess 225. The light shielding column is provided with a light guide hole 226, one end of the light guide hole 226 communicates with the light guide recess 225, and the other end penetrates through the rear side of the light shielding column.

[0043] It can be understood that the lamp beads are installed in the light guide cavity 225 of the light shielding column, and the light emitted by the lamp beads is scattered only backward from the light guide hole 226 of the light shielding column. With such a structure, when two groups of lamp beads are needed to set up for light display of the hair styling device working state, the light emitted by the two groups of lamp light will not have the problem of light cross, thereby ensuring that the user can clearly, accurately and reliably identify the state of the hair styling device; at the same time, since the light shielding column is located outside the first hollow part 221 and is isolated by the sealing sheet 23, it is ensured that the light generated by the light will not be scattered out of the button shell 24, thereby solving the problem that the light of the hair styling device leaks out from the gap of the button shell 24 in the traditional technology, thereby improving the visual comfort of the user during use, and making the overall visual effect of the hair styling device more advanced.

[0044] More specifically, the front surface of the sealing sheet 23 is provided with an abutting protrusion, which can pass through the first hollow part 221 and abut against the push switch. The push switch, the abutting protrusion and the button shell are sequentially arranged on the same axis.
