Description

Technical Field

[0001] This utility model belongs to the technical field of hair dryer equipment, specifically relating to a light-transmitting backlight panel for a hair dryer and a hair dryer. Background Technology

[0002] Hair dryers are primarily used for drying and styling hair, but they can also be used in laboratories, physiotherapy rooms, industrial production, and art settings for localized drying, heating, and therapeutic purposes. Based on the type of motor used, they can be categorized into AC series-wound, AC shaded-pole, and DC permanent magnet types.

[0003] As most hair dryers have become more standardized in terms of function, with little difference between them, existing hair dryers on the market have focused on improving their appearance to make them more aesthetically pleasing. One popular type is the hair dryer with a back cover that can light up. The principle behind the back cover of a hair dryer that can light up is generally as follows: a light panel is set up, and the light source is either side-mounted or front-mounted. Regardless of the method, the light source emitted by this type of back cover is relatively concentrated and does not easily diffuse. It is easy to see the point light source when viewed from the front. In view of this, this solution was developed. Utility Model Content

[0024] To make the above-mentioned features and advantages of this utility model more apparent and understandable, specific embodiments are described below in conjunction with the accompanying drawings for detailed explanation.

[0025] like Figure 1 - Figure 6 As shown, this embodiment provides a hair dryer, including a hair dryer body 1 and a hair dryer light-transmitting backlight plate 2.

[0026] The hair dryer body 1 has a mounting part 11 and a holding part 12. The holding part 12 is located below the mounting part 11. One end of the mounting part 11 is an air outlet, and the other end of the mounting part 11 has a mounting hole. The hair dryer's light-transmitting backlight panel 2 is installed in the mounting hole.

[0027] The backlight panel 2 of the hair dryer includes an outer shell 21, an inner shell 22, a light source chip assembly 23, a backlight panel 24, and a light-transmitting panel 25. The outer shell 21 is fitted around the outer periphery of the inner shell 22, and the outer shell 21 and the inner shell 22 are connected by a snap-fit.

[0028] The inner housing 22 has a through hole 225, and the light source chip assembly 23 is installed in the through hole 225. Specifically, the power supply component in the hair dryer body 1 is wired to the light source chip assembly 23. The light source chip assembly 23 includes a control chip board, which is an existing control chip board and will not be described in detail here. The control chip board can drive the backlight panel 24 to emit three colors of light: red, orange, and blue. A mounting ring 221 is formed around the periphery of the surface of the inner housing 22. The upper end of the mounting ring 221 has a notch 222. The upper end of the backlight panel 24 has a protrusion 241. The upper surface of the protrusion 241 is flat and a circuit interface is provided on the upper surface of the protrusion 241. The protrusion 241 extends out of the notch 222. The light-transmitting plate 25 is fitted in the mounting ring 221 and is located on the outward side of the backlight panel 24. The inner housing 22 has a plurality of downwardly extending pins 223 formed on its circumferential surface. The plurality of pins 223 are arranged in a ring at intervals along the axis of the inner housing 22. A retaining plate 224 is formed on the outer side of the pins 223 near the end. The upper surface of the retaining plate 224 is chamfered.

[0029] Multiple annularly spaced retaining plates 211 are formed on the surface of the outer shell 21 near its periphery. Each retaining plate 211 has a retaining hole 212. A retaining platform 224 is fitted into the retaining hole 212, allowing the outer shell 21 and inner shell 22 to engage. Two mirror-image limiting plates 213 are formed on the surface of the outer shell 21. The inward-facing side of each limiting plate 213 is sloped, and a protrusion 241 is secured between the two limiting plates 213. The sloped sides of the protrusion 241 are fitted into the inward-facing sloped sides of the two limiting plates 213. The outer shell 21 has a through hole with a diameter smaller than that of the light-transmitting plate 25. When the outer shell 21 is fitted onto the inner shell 22, the plate at the through hole of the outer shell 21 will limit the light-transmitting plate 25.

[0030] This solution involves installing the backlight panel 24 in the mounting ring 221 of the inner housing 22, and then inserting them together into the interior of the hair dryer body 1, so that the backlight panel 24 and the light-transmitting plate 25 face outwards. The light source chip assembly 23 is electrically connected to the power supply. When powered on, the backlight panel 24 emits light. The light emitted by the backlight panel 24 has uniform brightness and better visual effect. Moreover, the backlight panel 24 can emit three colors: red, orange, and blue, which consumers can switch according to their needs.
