In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0049] The following is combined with Figures 1 to 7 This application describes a light guide, a light-emitting component, and a hair dryer.

[0050] According to the embodiments of the first aspect of this application, such as Figure 5 , Figure 6 and Figure 7 As shown, the light guide 40 includes a light guide body 43, a light guide base 44, and an arc-shaped light guide portion 45. The first end of the light guide base 44 is connected to the light guide body 43, and the second end of the light guide base 44 forms a light guide cavity 41. The arc-shaped light guide portion 45 is disposed in the light guide cavity 41, and the middle area of ​​the arc-shaped light guide portion 45 protrudes from the bottom surface of the light guide cavity 41.

[0051] According to the embodiment of this application, when light from a light source shines on the light guide base 44 and the arc-shaped light guide portion 45, both the light guide base 44 and the arc-shaped light guide portion 45 can disperse the light to the light guide body 43, thereby guiding the light source and improving the light-emitting surface and light-emitting uniformity of a single light source. When light shines on the arc-shaped light guide portion 45, since the arc-shaped light guide portion 45 is located inside the light guide cavity 41, at least part of the reflected light after shining on the arc-shaped light guide portion 45 will be reflected to the inner wall surface of the light guide cavity 41, improving the light guiding efficiency of the light guide 40. Furthermore, by reflecting part of the light to the light guide base 44 through the arc-shaped light guide portion 45, the light can be avoided from concentrating at the arc-shaped light guide portion 45, that is, the light can be avoided from concentrating at the middle of the light guide 40, and the light can be uniformly transmitted to the light guide body 43, improving the light guiding uniformity of the light guide 40.

[0052] In one embodiment of this application, such as Figure 6 As shown, the vertical distance between the end face of the second end of the light guide seat 44 and the bottom surface of the light guide cavity 41 is H, and the maximum height of the arc-shaped light guide part 45 protruding from the bottom surface of the light guide cavity 41 is h, where h≤H.

[0053] It is understandable that setting the height between the top of the light guide seat 44 and the bottom surface of the light guide cavity 41 to be greater than the height between the top of the arc-shaped light guide part 45 and the bottom surface of the light guide cavity 41 allows the light guide seat 44 to better receive the reflected light from the arc-shaped light guide part 45, thereby improving the light guiding efficiency of the light guide component 40.

[0054] It is understandable that the end face of the second end of the light guide seat 44 is the highest point of the inner wall of the light guide cavity 41. The vertical distance between the end face of the second end of the light guide seat 44 and the light guide body 43 is greater than the vertical distance between the highest point of the arc-shaped light guide part 45 and the light guide body 43. This ensures that the arc-shaped light guide part 45 is located inside the light guide cavity 41, which allows more reflected light to be reflected to the inner wall of the light guide cavity 41, thereby improving the light guiding efficiency of the light guide part 40.

[0055] In one embodiment of this application, such as Figure 6 and Figure 7 As shown, the inner wall of the light guide cavity 41 gradually slopes away from the arc-shaped light guide part 45.

[0056] It is understandable that the inner wall of the light guide cavity 41 is set to gradually tilt away from the arc-shaped light guide portion 45 and away from the light guide body 43. That is, the inner wall of the light guide cavity 41 is expanded outward relative to the arc-shaped light guide portion 45, which increases the light receiving surface of the light guide seat 44, so that the light guide seat 44 can better receive the light from the light source and ensure the light guiding efficiency of the light guide 40.

[0057] In one embodiment of this application, such as Figure 6 As shown, the angle between the inner wall of the light guide cavity 41 and the central axis of the arc-shaped light guide part 45 is α, where 0°≤α≤50°.

[0058] Understandably, setting the angle between the inner wall of the light guide cavity 41 and the central axis of the arc-shaped light guide part 45 to 0° to 50° allows the light guide base 44 to simultaneously receive the light emitted by the light source and the reflected light at the arc-shaped light guide part 45, thus ensuring light guiding efficiency.

[0059] Understandably, to ensure uniform light guiding, the light source is typically positioned at the central axis of the arc-shaped light guide 45. In this embodiment, the angle between the inner wall of the light guide cavity 41 and the central axis of the arc-shaped light guide 45 is controlled between 0° and 50°, allowing the light guide base 44 to receive as much light as possible from the light source, as well as the reflected light from the arc-shaped light guide 45, thus ensuring the light guiding effect of the light guide component 40.

[0060] In one embodiment of this application, such as Figure 6As shown, the angle between the outer wall of the light guide seat 44 and the central axis of the arc-shaped light guide part 45 is b, where 0°≤b≤70°.

[0061] Understandably, setting the included angle between the outer wall of the light guide base 44 and the central axis of the arc-shaped light guide part 45 to any value between 0° and 70° ensures the light guiding efficiency of the light guide component 40.

[0062] It is understandable that, in order to ensure the uniformity of light guidance, the light source is generally set at the central axis of the arc-shaped light guide 45. In this embodiment, the central axis of the arc-shaped light guide 45 is also the central axis of the light source. That is, in this embodiment, the included angle between the outer wall surface of the light guide base 44 and the central axis of the light source is set to 0° to 70°, which ensures the light guiding efficiency of the light guide 40.

[0063] In one embodiment of this application, such as Figure 5 , Figure 6 and Figure 7 As shown, the outer wall surface of the arc-shaped light guide 45 is, for example, a spherical surface, so as to better reflect the reflected light to the inner wall surface of the light guide cavity 41.

[0064] For example, the spherical surface is the spherical surface of a sphere that is smaller than a hemisphere.

[0065] In one embodiment of this application, the arc-shaped light guide portion 45 is located at the center of the light guide cavity 41.

[0066] It is understandable that the arc-shaped light guide part 45 located at the center of the light guide cavity 41 can uniformly reflect light onto the inner wall surface of the light guide cavity 41, avoiding different amounts of reflected light received at different positions on the inner wall surface of the light guide cavity 41, and ensuring the uniformity of light guiding of the light guide component 40.

[0067] Understandably, when the light guide 40 is in use, the light source is generally directly facing the arc-shaped light guide portion 45, that is, the light source is located at the central axis of the arc-shaped light guide portion 45. However, in this embodiment, the arc-shaped light guide portion 45 is located at the center of the light guide cavity 41, so that the light source is also located on the central line of the light guide base 44, which allows the light source to evenly illuminate the light guide base 44, thus improving the light guiding uniformity of the light guide 40.

[0068] In one embodiment of this application, the light guide seat 44 is mirror-symmetrical about the central axis of the arc-shaped light guide portion 45.

[0069] It is understandable that the light guide seat 44 is symmetrical about the central axis of the arc-shaped light guide part 45, which ensures the uniformity of light guiding of the light guide seat 44. The light guide seat 44 can guide the light uniformly to the light guide body 43, thereby ensuring the uniformity of light guiding of the light guide 40.

[0070] In one embodiment of this application, the arc-shaped light guide portion 45 and the light guide base 44 are integrally formed.

[0071] Understandably, the arc-shaped light guide part 45 and the light guide base 44 are integrally formed, which improves the structural stability of the arc-shaped light guide part 45 and the light guide base 44.

[0072] In one embodiment of this application, the arc-shaped light guide portion 45 is detachably connected to the light guide base 44.

[0073] It is understandable that the arc-shaped light guide 45 can be detachably connected to the light guide base 44 by means of snap-fit, magnetic attraction, etc., so that different arc-shaped light guides 45 can be replaced as needed.

[0074] In one embodiment of this application, the light guide base 44 and the light guide body 43 are integrally formed.

[0075] Understandably, the light guide base 44 and the light guide body 43 are integrally formed, which improves the structural stability of the light guide 40.

[0076] In one embodiment of this application, the light guide base 44 is detachably connected to the light guide body 43.

[0077] It is understandable that the light guide base 44 can be detachably connected to the light guide body 43 by means of snap-fit, magnetic attraction, etc., so that different light guide bases 44 can be replaced as needed.

[0078] According to an embodiment of the second aspect of this application, such as Figure 3 and Figure 4 As shown, the light-emitting component includes a light-emitting element 30 and the aforementioned light guide element, with the light-emitting element 30 disposed in the light guide cavity.

[0079] According to the embodiments of this application, the light-emitting component has a light guide. When light from a light source shines on the light guide base 44 and the arc-shaped light guide portion 45, both the light guide base 44 and the arc-shaped light guide portion 45 can disperse the light to the light guide body 43, thereby guiding the light source and improving the light-emitting surface and light-emitting uniformity of a single light source. When light shines on the arc-shaped light guide portion 45, since the arc-shaped light guide portion 45 is located inside the light guide cavity 41, at least part of the reflected light after shining on the arc-shaped light guide portion 45 will be reflected to the inner wall surface of the light guide cavity 41, improving the light guiding efficiency of the light guide 40. Furthermore, by reflecting part of the light to the light guide base 44 through the arc-shaped light guide portion 45, the light can be avoided from concentrating at the arc-shaped light guide portion 45, that is, the light can be avoided from concentrating at the middle of the light guide 40, and the light can be uniformly transmitted to the light guide body 43, improving the light guiding uniformity of the light guide 40.

[0080] According to the embodiments of the third aspect of this application, such as Figure 3 and Figure 4As shown, the hair dryer includes a hair dryer body 10, a light-transmitting part 20, a light-emitting element 30, and a light guide 40. The light-transmitting part 20 is disposed on the outer wall surface of the hair dryer body 10, the light-emitting element 30 is disposed on the hair dryer body 10, and the light guide 40 is located between the light-emitting element 30 and the light-transmitting part 20. The light guide 40 is adapted to disperse the light emitted by the light-emitting element 30 into the light-transmitting part 20.

[0081] According to the embodiments of this application, the hair dryer controls the light-emitting element 30 to emit light. Since the light guide element 40 is located between the light-emitting element 30 and the light-transmitting part 20, when the light emitted by the light-emitting element 30 reaches the light guide element 40, the light guide element 40 can disperse the light emitted by the light-emitting element 30 and illuminate the light-transmitting part 20, so that the entire light-transmitting part 20 is illuminated. In other words, by using the light guide element 40 to disperse the light of the light-emitting element 30 before illuminating the light-transmitting part 20, it is possible to make the entire light-transmitting part 20 illuminate using only one or a few light-emitting elements 30, which can effectively reduce the number of light-emitting elements 30 used and reduce the cost of the hair dryer.

[0082] It is understandable that the light guide 40 is located between the light-emitting element 30 and the light-transmitting part 20, that is, the light-emitting element 30 and the light guide 40 are arranged opposite each other, so that the light emitted by the light-emitting element 30 can directly illuminate the light guide 40, ensuring the final luminous effect of the light-transmitting part 20. The light guide 40 and the light-transmitting part 20 are arranged opposite each other, so that the light guide 40 disperses the light and can directly illuminate the light-transmitting part 20, causing the light-transmitting part 20 to emit light.

[0083] It is understandable that the light-transmitting part 20 can be integrally formed with the hair dryer body 10. For example, a portion of the outer wall of the hair dryer body 10 can be made to transmit light as the light-transmitting part 20. The light-transmitting part 20 can also be installed on the outer wall of the hair dryer body 10 by means of bonding, snap-fitting, etc.

[0084] Understandably, the light-emitting element 30 is, for example, an LED bead or a surface-mount LED or any other suitable light source.

[0085] In one embodiment of this application, the light-emitting element 30 is located on the central axis of the light guide element 40.

[0086] It is understandable that placing the light-emitting element 30 at the central axis of the light guide element 40 allows the light guide element 40 to receive as much light as possible from the light-emitting element 30, improving the light guiding effect of the light guide element 40, ensuring the light-emitting effect of the light-transmitting part 20, and also allowing the light emitted by the light-emitting element 30 to evenly illuminate the light guide element 40, so that the light guide element 40 can evenly disperse the light into the light-transmitting part 20, ensuring the light-emitting uniformity of the light-transmitting part 20.

[0087] In one embodiment of this application, such as Figure 1 and Figure 2As shown, the hair dryer includes a circuit board 50, which is disposed on the hair dryer body 10, and a light-emitting element 30 is disposed on the circuit board 50.

[0088] It is understandable that by integrating the light-emitting element 30 onto the circuit board 50, the circuit board 50 can supply power to the light-emitting element 30 and control its operation, eliminating the need for a separate control board for installing and controlling the light-emitting element 30. This simplifies the structure of the hair dryer and reduces its cost.

[0089] In related technologies, hair dryers require a large number of LEDs, necessitating the addition of a light board. However, this application effectively reduces the need for a light-emitting element 30 by using a light guide 40. The light-emitting element 30 can be directly mounted on the circuit board 50 without requiring an additional light board, thus significantly reducing the cost of the hair dryer.

[0090] In the embodiments of this application, the light-emitting element 30 is mounted on the side of the circuit board 50 facing the light guide element 40.

[0091] It is understandable that the light-emitting element 30 is installed on the side of the circuit board 50 facing the light guide element 40, so that the light-emitting element 30 can face the light guide element 40 directly and the light emitted by the light-emitting element 30 can directly illuminate the light guide element 40.

[0092] In one embodiment of this application, such as Figure 2 As shown, the hair dryer body 10 has an installation cavity, the circuit board 50 is fixedly installed in the installation cavity, one end of the light guide 40 abuts against the circuit board 50, and the other end of the light guide 40 abuts against the wall of the installation cavity.

[0093] It is understandable that by installing the light guide 40 between the circuit board 50 and the wall of the mounting cavity, and with both the circuit board 50 and the wall of the mounting cavity abutting against the light guide 40, the light guide 40 can be limited, keeping it stable. Stable installation of the light guide 40 can be achieved without additional screws or other fasteners, and the structure of the hair dryer is also more compact.

[0094] In one embodiment of this application, such as Figure 2 and Figure 4 As shown, a light guide cavity 41 is formed at one end of the light guide 40 near the circuit board 50, and at least part of the light-emitting element 30 is located in the light guide cavity 41.

[0095] It is understandable that placing at least part of the light-emitting element 30 inside the light guide cavity 41 can effectively increase the amount of light that the light guide element 40 can receive and improve the light guiding efficiency.

[0096] In one embodiment of this application, such as Figure 1 and Figure 2As shown, the hair dryer body 10 includes a body 11 and a handle 12. The handle 12 is connected to the body 11. The first end of the body 11 is provided with an air outlet, and the second end of the body 11 is provided with a light-transmitting part 20.

[0097] Understandably, placing the light-transmitting part 20 at the end away from the air outlet can reduce the impact of the high temperature at the air outlet on the light-emitting element 30.

[0098] In one embodiment of this application, such as Figure 1 and Figure 2 As shown, the hair dryer body 10 includes a body 11 and a handle 12. The handle 12 is connected to the body 11 and has a light-transmitting part 20.

[0099] It is understandable that a light-transmitting part 20 is provided at the handle 12, so that the light emitted by the light-emitting element 30 can pass through the handle 12 after being dispersed by the light guide 40, making the handle 12 emit light and improving the user experience of the hair dryer.

[0100] In one embodiment of this application, such as Figure 2 and Figure 3 As shown, the hair dryer includes a light-shielding member 60, which is connected to the side of the light guide member 40 facing the light-transmitting part 20. The light-shielding member 60 is adapted to block a portion of the area of ​​the side of the light guide member 40 facing the light-transmitting part 20.

[0101] It is understandable that the side of the light guide 40 facing the light-transmitting part 20 is the light-emitting surface of the light guide 40. By blocking part of the light-emitting surface of the light guide 40 by the light-shielding part 60, the shape of the light transmitted from the light guide 40 to the light-transmitting part 20 can be changed, so that the light-transmitting part 20 displays the desired shape, thereby improving the light display effect of the hair dryer.

[0102] In one embodiment of this application, such as Figure 4 As shown, the light guide 40 includes at least two light guide blocks 42, which are spliced ​​together to form the light guide 40.

[0103] Understandably, the light guide 40 is divided into at least two light guide blocks 42 to avoid injection molding difficulties caused by the large thickness of the light guide 40. The different light guide blocks 42 can be manufactured separately and then spliced ​​together to form the light guide 40.

[0104] Finally, it should be noted that the above embodiments are only used to illustrate this application and are not intended to limit this application. Although this application has been described in detail with reference to the embodiments, those skilled in the art should understand that various combinations, modifications, or equivalent substitutions of the technical solutions of this application do not depart from the spirit and scope of the technical solutions of this application and should be covered within the scope of the claims of this application.
