Description

Technical Field

[0001] The utility model relates to the technical field of electrical appliances, in particular to a light display component and a hair dryer. Background Art

[0002] Hair dryers are a common household appliance primarily used for drying and styling hair and are widely used in daily life. With the development of related technologies and the improvement of people's quality of life, people's expectations for the user experience of hair dryers have also increased. Common hair dryers on the market currently rely primarily on wind power and high temperatures to dry hair. While they can dry hair quickly, the high temperature and strong wind force can cause hair to become dry and frizzy after drying. Long-term use can also damage hair and is not conducive to styling.

[0003] In the prior art, in order to improve the user's hair-drying experience, an ion hair dryer has been proposed, in which a water ion generator is integrated into the air duct of the hair dryer. As a result, the airflow blown out by the hair dryer during operation carries negatively charged ion particles generated by the water ion generator, which neutralize the positive charge commonly found in the hair, thereby smoothing out the messy hair and making it smooth and tame. It can also eliminate static electricity, making the hair smoother and easier to comb, and achieving a more ideal styling effect.

[0004] However, the amount of water ions generated by the water ion generator is limited, and it is difficult for a user to directly determine the water ion content in the water ion generator by observation.

[0005] On the other hand, existing household appliances, such as handheld household appliances such as hair dryers, generally use exposed or simply shielded light-emitting units to display information such as mode and switch. The brightness of the light-emitting units (such as LED lamp beads, light sheets, etc.) is too high. If the light shines directly into the eyes, it will have a "grainy" feeling and be dazzling when observed, affecting the user experience. Utility Model Content

[0006] In view of the above problems, the utility model provides a light display assembly and a hair dryer having the light display assembly, which can eliminate the "graininess" of the light-emitting unit.

[0007] The utility model provides a light display assembly, which includes a light source board, a first light shielding member, a curved light guide plate and a second light shielding member. A light emitting unit is provided on the front surface of the light source board, and the two sides of the light emitting unit are respectively a first side and a second side in a direction parallel to the light source board. The first light shielding member includes a first main body and a first light shielding plate, the first main body is provided on the first side of the light emitting unit, one end of the first light shielding plate is located on the first side of the light emitting unit and is connected to the first main body, and the other end extends to the second side in front of the light emitting unit. One end of the curved light guide plate abuts or is adjacent to the front surface of the light emitting unit, and the other end extends obliquely to the second side of the first light shielding plate, the second light shielding member includes a second main body and a second light shielding plate, the second main body is provided on the second side of the light emitting unit, one end of the second light shielding plate is connected to the second main body, and the other end extends to the second side of the light emitting unit behind the curved light guide plate and abuts or is adjacent to the light emitting unit.

[0008] According to the technical solution of the present invention, the light display assembly can limit the direction of the light emitted by the light-emitting unit on the light source board to be incident forward into the curved light guide plate by setting the first light-shielding member and the second light-shielding member, thereby preventing the light emitted by the light-emitting unit from leaking sideways. The light incident on the curved light guide plate cannot be directly emitted through the light guide plate due to the obstruction of the first light-shielding member on the front side, but will be refracted inside the curved light guide plate and guided to the end of the curved light guide plate extending from the second side of the first light-shielding member, thereby preventing the light of the light-emitting unit from directly entering the eyes and eliminating the "graininess" of the light-emitting unit. Since the second light-shielding member blocks light on the back of the curved light guide plate, the light is limited to being emitted forward from the curved light guide plate, and the light emitted by the light display assembly is more uniform and soft, and will not be dazzling.

[0009] As a preferred technical solution, the first main body portion and / or the second main body portion extends to the light source board or extends to the rear of the light source board.

[0010] According to this preferred technical solution, the first main body portion and the second main body portion are arranged on both sides of the light source board, and the first main body portion and / or the second main body portion extend to the light source board or extend to the back of the light source board, which can better block the light emitted by the light-emitting unit to the first side and / or the second side, thereby achieving more all-round light blocking.

[0011] As a preferred technical solution, one end of the first light shielding plate extending to the second side has an abutting portion, and the abutting portion is configured to be an arc that matches the shape of the curved light guide plate.

[0012] According to this preferred technical solution, the degree of fit between the first light shielding plate and the curved light guide plate at the joint is increased, which can further prevent direct light leakage.

[0013] As a preferred technical solution, the front side surface of the second light shielding plate is constructed into a shape that matches and fits the rear side surface of the curved light guide plate.

[0014] According to this preferred technical solution, the front side surface of the second shading plate can be extended to fit with the curved light guide plate, which can further avoid light leakage on the one hand, and promote multiple refractions of light inside the curved light guide plate on the other hand, making the luminous surface more uniform and soft.

[0015] As a preferred technical solution, the front side surface of the curved light guide plate is a smooth surface, and the rear side surface of the curved light guide plate is a three-dimensional textured surface.

[0016] According to this preferred technical solution, the smooth surface can increase the light transmittance effect of the front side, while the three-dimensional textured surface on the back side can prevent the generation of a mirror image of the front object and increase the refraction and reflection of light inside the curved light guide plate, making the lighting more uniform.

[0017] As a preferred technical solution, the front side surface and the rear side surface of the curved light guide plate are both curved surfaces without sharp edges.

[0018] According to this preferred technical solution, due to the refraction and reflection properties of light, it is easy to focus at the corners, thereby forming local bright spots, affecting the overall light uniformity effect. By forming the front and rear sides of the curved light guide plate into curved surfaces without edges and corners, the formation of local bright spots can be effectively avoided.

[0019] As a preferred technical solution, the second light shielding plate includes a flat plate portion and a curved plate portion. The flat plate portion extends parallel to the light source plate. The curved plate portion bends rearward from the end of the flat plate portion and extends obliquely to abut or abut against the light-emitting unit. The curved light guide plate includes a first extension portion, a bent portion, and a second extension portion connected in sequence. The rear side of the first extension portion abuts against the front side of the flat plate portion. The bent portion extends through the gap between the flat plate portion and the first light shielding plate and extends to the rear of the first light shielding plate. The second extension portion extends to abut or abut against the front side of the light-emitting unit.

[0020] According to this preferred technical solution, by arranging the first light shading plate, the curved light guide plate and the second light shading plate in abutment with each other, the structure of the light display assembly can be made more compact, and the curved light guide plate except for the light-emitting surface is blocked by the first light shading plate and the second light shading plate, thereby reducing light loss and making the lighting more uniform.

[0021] A second aspect of the present invention provides a hair dryer having a light display assembly according to any one of the above technical solutions.

[0022] As a preferred technical solution, the hair dryer includes a main body and a handle, the handle is connected to the side of the main body, one end of the main body constitutes the air outlet end of the hair dryer, the first light shading member, the curved light guide plate and the second light shading member are all arranged at the air outlet end, the first light shading member is arranged at the radial outer edge of the air outlet end, the second light shading member is arranged in the center of the air outlet end, and the curved light guide plate is arranged between the first light shading member and the second light shading member along the radial direction of the air outlet end.

[0023] According to this preferred technical solution, since the air outlet of the hair dryer is facing the user when in use, the user can easily observe the information displayed by the light display component. Moreover, since the light of the light display component is soft and there is no direct light source, it will not be dazzling, which can improve the user experience.

[0024] As an optimal technical solution, the air outlet includes a main air outlet and a water ion outlet. The hair dryer has a water ion generator. The main air outlet is arranged on the first shading member, the water ion outlet is arranged on the second shading member, and the water ion generator is arranged behind the water ion outlet.

[0025] According to this preferred technical solution, the first and second shading members are fixedly arranged on the wall surfaces at the main air outlet and the water ion outlet of the hair dryer, so that the overall structure of the hair dryer is compact, which is conducive to the miniaturization of the hair dryer.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] In addition, for any single technical feature described or implied in the embodiments mentioned in this document, or any single technical feature shown or implied in the accompanying drawings, this application still allows for continued arbitrary combination or deletion between these technical features (or their equivalents) without any technical obstacles, thereby obtaining more other embodiments of the present application that may not be directly mentioned in this document.

[0033] Here, "front" refers to the side of the light source board where the light emitting unit is provided. In other words, it is the side of the user toward which the light emitting unit emits light. Figure 1 In the light display assembly shown, the top is the front, and the Figure 2 The hair dryer shown is used on the side facing the user (i.e. Figure 2 The left side in the figure is the front, and the left end of the hair dryer is provided with air outlets (main air outlet and water ion outlet), which is also the air outlet end of the hair dryer; "rear" refers to the side of the light source board away from the light-emitting unit. Figure 1 In the light display assembly shown, the bottom is the rear, and the Figure 2 The hair dryer shown is used on the side away from the user (i.e. Figure 2 on the right side of the ).

[0034] "Shading member" refers to a component that can block light. Its shading property can be formed by selecting a light-proof material for the shading member, or it can be formed by applying a shading coating to a part of the whole, without limitation.

[0035] Figure 1 This is a schematic diagram of the structure of the light display assembly provided by the embodiment of the present utility model. Figure 1 As shown, the light display assembly 100 includes a light source board 1 , a first light shielding member 2 , a curved light guide plate 3 and a second light shielding member 4 .

[0036] Among them, the light source board 1 can be a substrate with any light-emitting unit 11, such as a PCB circuit board, etc., and the type of the light-emitting unit 11 is not limited, and it can be an LED lamp bead, a light strip, a lamp tube or other forms of light-emitting structures. The light-emitting unit 11 is fixed on the front surface of the light source part, and the light source board 1 can control the light-emitting unit 11 to emit light toward the front or turn it off, or in some preferred embodiments, the light-emitting unit 11 can be an RGB lamp bead, so that the light-emitting unit 11 can be controlled to emit lights of different colors, and the user is prompted by light signals of different colors of water ions in the hair dryer. In addition, in the direction parallel to the light source board 1, the two sides of the light-emitting unit 11 are the first side and the second side respectively. Specifically, Figure 1 The example shows that the light source board 1 of the lamp tube display assembly is formed as a hollow ring. In this case, the first side of the light emitting unit 11 refers to the radial outer side of the light emitting unit 11, and the second side of the light emitting unit 11 refers to the radial inner side of the light emitting unit 11.

[0037] The first light shielding member 2 includes a first main body portion 21 and a first light shielding plate 22. The first main body portion 21 is disposed on a first side of the light emitting unit 11. Figure 1 The first light shielding plate 22 is located on the outside of the light emitting unit 11, one end of the first light shielding plate 22 is located on the first side of the light emitting unit 11 and connected to the first main body 21, and the other end extends to the second side in front of the light emitting unit 11. Figure 1 As shown, the first main body 21 is arranged on the first side of the light-emitting unit 11, and the first light-shielding plate 22 extends from the oblique upper side of the first side of the light-emitting unit 11 to the oblique upper side of the second side of the light-emitting unit 11, thereby blocking the light emitted directly forward by the light-emitting unit 11, preventing the light from directly entering the eyes, and improving the user experience.

[0038] The curved light guide plate 3 has light-guiding properties, and light can be refracted inside the curved light guide plate 3, thereby enabling the curved light guide plate 3 to form a uniform and soft light-emitting surface. In some embodiments, the light guide plate can be obtained by adding a light diffusing agent to a light-transmitting material. In this embodiment, one end of the curved light guide plate 3 abuts or adjoins the front surface of the light-emitting unit 11, thereby receiving the light emitted by the light-emitting unit 11. The light enters the curved light guide plate 3 and is transmitted, while the other end of the curved light guide plate 3 extends obliquely to the second side of the first light shielding plate 22, from the front ( Figure 1 When observing from the upper side of the first shading plate 22, only the end portion of the curved light guide plate 3 extending from the second side of the first light shielding plate 22 can be seen, and the direct light cannot be observed.

[0039] The second light shielding member 4 includes a second main body portion 41 and a second light shielding plate 42. The second main body portion 41 is arranged on the second side of the light emitting unit 11. Figure 1On the inner side of the light emitting unit 11, one end of the second light shielding plate 42 is connected to the second main body 41, and the other end extends to the second side of the light emitting unit 11 behind the curved light guide plate 3 and abuts or is adjacent to the light emitting unit 11. Figure 1 As shown, the second main body 41 is on the second side of the light-emitting unit 11, and the second light-shielding plate 42 extends along the back of the curved light guide plate 3 toward the light-emitting unit 11 until it abuts against the second side of the light-emitting unit 11, so that the light from the light-emitting unit 11 to the first side and the second side is blocked, and only the forward light can be incident on the curved light guide plate 3.

[0040] In this embodiment, first, the light display assembly 100 is adaptable to a hair dryer, so that the user can directly observe and confirm the water ion content in the hair dryer through the light display assembly 100. Secondly, by providing the first light shielding member 2 and the second light shielding member 4, the light emitted by the light-emitting unit 11 on the light source panel 1 can be restricted to only be incident forward into the curved light guide plate 3, thereby preventing the light emitted by the light-emitting unit 11 from directly leaking out. The light incident on the curved light guide plate 3 cannot pass directly through the light guide plate due to the obstruction of the first light shielding member 2 on the front side. Instead, it will be refracted within the curved light guide plate 3 and guided to the end of the curved light guide plate 3 extending from the second side of the first light shielding member 22, thereby preventing the light from the light-emitting unit 11 from directly entering the eye and eliminating the "graininess" of the light-emitting unit. Because the second light shielding member 4 blocks light on the back of the curved light guide plate 3, the light is restricted to being emitted forward from the curved light guide plate 3, and the light emitted by the light display assembly 100 is more uniform and soft.

[0041] It should be noted that, for the sake of convenience, the light display assembly 100 is described here as being applied to a hair dryer, but the light display assembly 100 provided by the present invention is not only adaptable to hair dryers, but can also be applied to other electrical appliances. Moreover, when the light display assembly 100 is applied to other electrical appliances, it can also avoid glare from direct light and improve the user experience, which falls within the scope of protection of the present invention.

[0042] The following, combined with the Figure 1 The specific structure of the light display assembly 100 is further described in detail.

[0043] like Figure 1 As shown, the first main body portion 21 and the second main body portion 41 are arranged on both sides of the light source board 1. In order to further prevent light leakage, the first main body portion 21 and / or the second main body portion 41 can be preferably extended to the light source board 1 or extended to the back of the light source board 1, so as to better block the light emitted by the light-emitting unit 11 to the first side and / or the second side, thereby achieving more all-round light blocking.

[0044] Further preferably, light leakage can be further reduced by increasing the fit between the first light shielding plate 22 and / or the second light shielding plate 42 and the curved light guide plate 3. For example, the end of the first light shielding plate 22 extending to the second side has an abutment portion 221. The abutment portion 221 is preferably constructed in an arc shape that matches the shape of the curved light guide plate 3, so that the two abut and fit together, preventing direct light leakage. Further preferably, the front side surface of the second light shielding plate 42 can also be constructed in a shape that matches the rear side surface of the curved light guide plate 3. The front side surface of the second light shielding plate 42 can extend in a fit with the curved light guide plate 3, which can not only further prevent light leakage, but also promote multiple refractions of light within the curved light guide plate 3, resulting in a more uniform and softer luminous surface.

[0045] In some preferred embodiments, the front side of the curved light guide plate 3 can be formed into a smooth surface, and the rear side of the curved light guide plate 3 can be formed into a three-dimensional textured surface. The smooth surface can increase the light transmittance of the front side, while the three-dimensional textured surface on the rear side can prevent the formation of a mirror image of the object on the front side and increase the refraction and reflection of light within the curved light guide plate 3, making the lighting distribution more uniform. The three-dimensional textured surface is preferably a sun-textured surface, but those skilled in the art will understand that in addition to the sun-textured surface, three-dimensional textured surfaces produced by processes such as frosting and sandblasting can also achieve the same effect.

[0046] Furthermore, the front and rear sides of the curved light guide plate 3 can be formed as smooth curved surfaces. Due to the refraction and reflection properties of light, light tends to be concentrated at corners, thereby forming local bright spots and affecting the overall light uniformity effect. By forming the front and rear sides of the curved light guide plate 3 as smooth curved surfaces, the formation of local bright spots can be effectively avoided.

[0047] Specifically, in some preferred embodiments, the second shading plate 42 includes a flat plate portion 421 and a curved plate portion 422. The flat plate portion 421 extends in a direction parallel to the light source panel 1, and the curved plate portion 422 is bent backward from the end of the flat plate portion 421 and extends obliquely until it abuts or is adjacent to the light-emitting unit 11.

[0048] Correspondingly, the curved light guide plate 3 has a first extension portion 31, a bent portion 32, and a second extension portion 33, which are sequentially connected. The rear side of the first extension portion 31 abuts against the front side of the flat portion 421. The bent portion 32 passes through the gap between the flat portion 421 and the first light shielding plate 22 and extends to the rear of the first light shielding plate 22. The second extension portion 33 extends until it abuts or abuts against the front side of the light-emitting unit 11.

[0049] In this embodiment, by fitting and abutting the first light shading plate 22, the curved light guide plate 3 and the second light shading plate 42, the structure of the lighting display assembly 100 can be made more compact, and the curved light guide plate 3 except for the light-emitting surface is shielded by the first light shading plate 22 and the second light shading plate 42, thereby reducing light loss and making the lighting more uniform.

[0050] Figure 2 This is a schematic diagram of the structure of a hair dryer provided by the embodiment of the utility model. Figure 2 As shown, the hair dryer includes a main body 300 and a handle 200, the handle 200 is connected to the side of the main body 300, one end of the main body 300 constitutes the air outlet end of the hair dryer, and the hair dryer also has a light display component 100 in any of the above-mentioned embodiments, and the light display component 100 can be set on the main body 300 or the handle 200, without limitation.

[0051] Among them, preferably, combined Figure 2 and Figure 3 From a general perspective, the light display assembly 100 is disposed on the main body 300, making it convenient for the user to observe the light display assembly 100 when holding the handle 200. Furthermore, the first light shielding member 2, the curved light guide plate 3, and the second light shielding member 4 are all disposed at the air outlet end. The first light shielding member 2 is disposed at the radial outer edge of the air outlet end, the second light shielding member 4 is disposed at the center of the air outlet end, and the curved light guide plate 3 is disposed between the first light shielding member 2 and the second light shielding member 4 along the radial direction of the air outlet end. Since the air outlet end of the hair dryer is facing the user when in use, the user can easily observe the information displayed by the light display assembly 100. Moreover, since the light of the light display assembly 100 is soft and there is no direct light source, it will not be dazzling, which can improve the user experience.

[0052] Further preferably, the air outlet includes a main air outlet 301 and a water ion outlet 302, and the hair dryer has a water ion generator 303. The main air outlet 301 is provided on the first light shielding member 2, the water ion outlet 302 is provided on the second light shielding member 4, and the water ion generator 303 is provided behind the water ion outlet 302. The first light shielding member 2 and the second light shielding member 4 are fixedly provided on the wall surface at the main air outlet 301 and the water ion outlet 302 of the hair dryer, making the overall structure of the hair dryer compact and facilitating miniaturization of the hair dryer.

[0053] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
