DETAILED DESCRIPTION

[0048] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0049] In the description of this utility model, it should be noted that, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; and direct connections or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0050] In the prior art, those skilled in the art typically install a light-emitting element 100 inside the toothbrush handle. The light emitted by the light-emitting element 100 passes through the lampshade on the outer shell, creating a better visual effect. However, when there are multiple light-emitting areas, light crosstalk is prone to occur, making it difficult for users to distinguish the indicator lights, causing trouble. Traditional sonic motor toothbrushes use EVA foam glued to the mainboard to separate the lights in four areas. However, the EVA foam easily deforms during assembly and covers the LED light on the mainboard, preventing the light from shining on the outer lampshade.

[0051] Compared with the existing solution of separating the lights in four areas by sticking EVA foam on the mainboard, there are many problems, such as the foam itself is easy to deform, the effect of separating the lights is weak, and the user experience is poor.

[0052] In view of the technical problems existing in the above-mentioned prior art, the present utility model is hereby proposed.

[0053] The present invention achieves this by arranging a light isolation member 300 inside the shell 400, and arranging the light isolation member 300 between the light-emitting member 100 and the light-transmitting member 200. The light isolation member 300 is used to separate the illumination light on the light-emitting member 100, so that the illumination light of each light-emitting area will not interfere with each other and can accurately illuminate the corresponding light-transmitting area.

[0054] Example 1

[0055] like Figure 1-5 As shown, the present invention provides a personal care device comprising a housing 400 and a light-transmitting member 200, further comprising a light-emitting member 100 and a light-isolating member 300. The housing 400 extends along a first axis 600, and the light-transmitting member 200 extends between the inner and outer surfaces of the housing 400. The light-emitting member 100 is disposed within the housing 400 and includes multiple light sources. The light-isolating member 300 is disposed between the light-emitting member 100 and the light-transmitting member 200, separating the multiple light sources into different light-emitting zones.

[0056] The light emitted by the light sources in different light-emitting areas illuminates the corresponding portion of the light-transmitting member 200 , so that the light emitted by the light sources in different light-emitting areas is visible on the outer surface of the corresponding portion of the light-transmitting member 200 .

[0057] See Figure 1 The housing 400 extends along a first axis 600 toward the head and tail, respectively. A receiving space is provided within the housing 400, within which a light-emitting element 100 is disposed. The light-emitting element 100 is inserted into the receiving space within the housing 400 from the tail. Light emitted by the light-emitting element 100 can directly illuminate the light-transmitting element 200, which then transmits the light to the surface of the personal care device, creating a uniform light effect.

[0058] See Figure 2 It should be noted that the housing 400 wraps around the surface of the light-transmitting element 200, and the housing 400 and the light-transmitting element 200 are bonded together using a two-shot mold injection molding or a two-shot lamination method. The specific injection molding process used in this embodiment will not be described in detail here, and please refer to the brief description in Example 2.

[0059] See Figure 1 and 3 A light barrier 300 is provided between the light emitting element 100 and the light transmissive element 200 to separate the light emitted by the light emitting element 100. The light barrier 300 is provided above the light emitting element 100 to separate the light emitting element 100 into different light emitting zones, so that the light from different light emitting zones does not interfere with each other and is irradiated onto the light transmissive element 200.

[0060] As a specific embodiment, the light-isolating member 300 is bonded to the light-emitting surface of the light-emitting member 100. Those skilled in the art will understand that the light-isolating member 300 and the light-emitting member 100 can be connected together using any feasible connection method, such as a snap connection or ultrasonic welding.

[0061] See Figure 1 and 4 In this embodiment, a plurality of light sources are provided on the light-emitting surface, and the light-isolating member 300 includes a plurality of first partitions 310. The first partitions 310 extend along the direction of the irradiated light and are provided between adjacent light sources, and are configured to separate the irradiation light paths of adjacent light sources.

[0062] As a specific embodiment, the light emitting element 100 is configured as a circuit board, which provides light emitting energy to the light source and can control the on and off of the light source.

[0063] As a specific embodiment, the first partition 310 is made of a substantially opaque elastic material. This arrangement allows the first partition 310 to be elastically pressed against the inner wall of the housing 400 to avoid light leakage due to gaps.

[0064] See Figure 1 Multiple light sources are provided at one end of the light-emitting element 100 near the head of the housing 400. The side of the light-emitting element 100 facing the light-transmitting element 200 is provided as a light-emitting surface, and a circle of light sources is arranged at intervals along the edge of the light-emitting surface. The light sources are provided to emit light onto the light-transmitting element 200. Those skilled in the art will also appreciate that the light sources can be replaced by any other feasible light-emitting device, such as an LED lamp.

[0065] Specifically, the first partition 310 extends outward from the light emitting surface and extends along the direction of the irradiated light. The first partition 310 separates the irradiation light paths of adjacent light sources.

[0066] As a specific embodiment, the extension length of the first partition 310 is set according to the actual needs of technical personnel in this field. For example, the first partition 310 extends to the surface of the light-transmitting member 200 to avoid gaps in the light path from the light source to the light-transmitting member 200, thereby avoiding light leakage or light crosstalk.

[0067] Specifically, one end of the first partition 310 divides the light-emitting surface into multiple light-emitting zones, while the other end of the first partition 310 divides the light-transmitting surface into multiple light-transmitting zones. Light within the light-emitting zones is directed onto the light-transmitting surfaces accordingly. By providing the first partition 310, the light-emitting surface and the light-transmitting surface can be separated simultaneously, ensuring that light within the light-emitting surface is directed onto the corresponding light-transmitting surfaces.

[0068] As a specific embodiment, two mutually perpendicular first dividers 310 are provided above the light-emitting surface. The two first dividers 310 are arranged in a cross shape, which can divide the light-emitting surface into four light-emitting areas. By providing two first dividers 310, the light-emitting surface is divided into four light-emitting areas, and the light irradiated by each light-emitting area is separated by the first dividers 310.

[0069] See Figure 1 and 4 In this embodiment, one side of the first partition 310 is connected to a light-isolating plate 320, and the other side of the light-isolating plate 320 is connected to the light-emitting surface. Adjacent first partitions 310 divide the light-emitting surface into several light-emitting areas, and the light in the light-emitting area is irradiated into the corresponding light-transmitting area.

[0070] First, one side of the light-isolating plate 320 is bonded to the light-emitting surface, which facilitates placing the first partition 310 connected to the other side of the light-isolating plate 320 between the light sources. This arrangement facilitates the first partition 310 to better play the role of separating the irradiated light.

[0071] Secondly, the first partition 310 is connected to the light-emitting element 100 via a light-isolating plate 320. The presence of the light-isolating plate 320 increases the contact area between the first partition 310 and the light-emitting element 100. This arrangement ensures that the positioning of the first partition 310 is not affected by moving, cleaning, or dropping the personal care device while the user is using it; ensures that the first partition 310 is always located between adjacent light sources to separate the illumination paths of the illumination light; and ensures that adjacent light-emitting areas do not interfere with each other.

[0072] See Figure 4 The lower end of the first partition 310 is connected to the light-isolating plate 320, and the first partition 310 is connected to the light-emitting element 100 through the light-isolating plate 320. Four first partitions 310 are arranged around the light-isolating plate 320, with adjacent first partitions 310 perpendicular to each other. When the light-isolating plate 320 is connected to the light-emitting surface of the light-emitting element 100, two adjacent first partitions 310 divide the light-emitting surface into four light-emitting areas.

[0073] Specifically, two escape holes are provided on the light-isolating plate 320. When the light-isolating plate 320 is bonded to the light-emitting surface, the light source passes through the escape holes through the light-isolating plate 320, illuminating the light-transmitting member 200. A first partition 310 is provided in the middle of the escape holes to separate the light source passing through the escape holes and onto the light-transmitting member 200. The edge of the light-isolating plate 320 is recessed inward to form an escape space. This escape space allows the light source on the light-emitting surface to be shielded from view when the light-isolating plate 320 is attached to the light-emitting surface.

[0074] In this embodiment, one end of the first partition 310 is connected to a light-isolating plate 320, and the light-isolating plate 320 also includes a second partition 410 connecting at least two adjacent first partitions 310. The second partition 410 is configured to extend from the light-isolating plate 320 toward the inner surface of the shell 400, and together with the at least two adjacent first partitions 310, form a light-isolating area that is not transparent to light from other areas.

[0075] Specifically, the second partition 410 is formed by extending a certain length of the first partition 310 toward the inner surface of the shell 400, or the second partition 410 is configured as a circular partition plate connected to the first partition 310.

[0076] Specifically, one end of the first partition 310 extends from the light-isolating plate 320 toward the light source. The first partition 310 extends between adjacent light sources and separates the light emitted by the light sources. One end of the second partition extends from the light-isolating plate 320 toward the inner surface of the housing 400. This can also be understood as the second partition extending away from the extension direction of the first partition 310.

[0077] Specifically, the second partition 410 is configured as a circular partition plate connecting the radial ends of the first partition 310. The inner circumference of the second partition 410 is connected to the radially outer ends of the four first partitions 310. The second partition 410 encloses the first partitions 310, and the second partition 410 and two adjacent first partitions 310 together enclose and divide the light emitted by the light source. Alternatively, the outer circumference of the second partition 410 is connected to the radially inner ends of the four first partitions 310. Alternatively, the outer circumference of the second partition 410 is connected to the radially inner ends of the four first partitions 310. This can also be understood as the four first partitions 310 extending radially outward from the outer circumference of the second partition 410.

[0078] Please continue to see Figure 4 In this embodiment, at least one light source is distributed in the light-emitting area, the horizontal end of the first partition 310 extends a certain length from the radial inner side to the radial outer side of the light-isolating plate 320, and the vertical end of the first partition 310 extends a certain height from the surface of the light-isolating plate 320 toward the light-transmitting member 200.

[0079] Two light sources are disposed in each light emitting area for emitting illumination light toward the light-transmitting member 200 .

[0080] An extension portion (not marked) is provided on the edge of the light-isolating plate 320 to extend outward, and a first partition portion 310 is provided on the extension portion (not marked). The horizontal end of the first partition portion 310 extends toward the center of the light-isolating plate 320 along the extension direction of the extension portion (not marked), and the vertical end of the first partition portion 310 extends away from the light-isolating plate 320 toward the light-transmitting member 200 along the extension direction of the extension portion (not marked).

[0081] Preferably, the vertical end of the first partition 310 extends to abut against the housing 400. The purpose of this arrangement is to simultaneously separate the light-emitting area and the light-transmitting area through the first partition 310, and at the same time, to ensure that the positions and numbers of the light-emitting areas and the light-transmitting areas correspond one to one, so that the light emitted by the light-emitting area is directly irradiated on the corresponding light-transmitting area, avoiding the presence of gaps that cause light leakage and crosstalk, avoiding interference in the light path during the illumination process, and avoiding light leakage between adjacent light-transmitting areas.

[0082] As a specific implementation manner, the light isolation plate 320 and the first partition 310 are made of silicone material.

[0083] Example 2

[0084] The injection molding connection between the housing 400 and the light-transmitting member 200 in one embodiment is briefly described as follows:

[0085] The housing 400 and the light-transmitting element 200 are formed using a two-shot injection molding or two-shot overlay molding scheme. The light-transmitting element 200 is formed using a single injection molding process using the corresponding mold, and the housing 400 is then formed on the surface of the light-transmitting element 200 using a secondary injection molding process. When the housing 400 and the light-transmitting element 200 are connected using secondary injection molding, the housing 400 will deform when wrapping around the surface of the light-transmitting element 200, resulting in the housing 400 not meeting the designed precision between the two elements.

[0086] To do this, see Figure 1 、 2 3. Unlike Example 1, in this embodiment, the light-transmitting member 200 is disposed on the inner side of the housing 400, and a portion of the light-transmitting member 200 extends beyond the outer circumferential surface of the housing 400. A positioning portion 210 is provided on the light-transmitting member 200, which connects the housing 400 and the light-transmitting member 200. By providing the positioning portion 210 on the light-transmitting member 200, the positioning portion 210 serves as a positioning point for bonding the light-transmitting member 200 and the housing 400 through two-color injection molding or two-shot lamination, thereby preventing the housing 400 from being skewed during injection molding; at the same time, the uniformity of the thickness of the housing 400 wrapped around the light-transmitting member 200 is ensured.

[0087] See Figure 2 In this embodiment, the positioning portion 210 includes a first positioning portion 2100 and a second positioning portion 2110. The first positioning portion 2100 extends outward from the surface of the light-transmitting member 200 to a certain height. At least two second positioning portions 2110 are provided, and the second positioning portions 2110 are provided through the light-transmitting member 200.

[0088] Specifically, one end of the first positioning portion 2100 is connected to the surface of the light-transmitting member 200, and the other end of the first positioning portion 2100 extends away from the surface of the light-transmitting member 200. The purpose of providing the first positioning portion 2100 protruding from the light-transmitting member 200 is to provide a support point when the housing 400 wraps around the light-transmitting member 200, while also applying a force in a certain direction to the housing 400 to limit injection deformation of the housing 400.

[0089] Specifically, the second positioning portion 2110 is configured as a through hole or a threaded hole. The purpose of providing the second positioning portion 2110 that passes through the light-transmitting member 200 is to apply a force in a certain direction to the housing 400 when the housing 400 enters the second positioning portion 2110 during injection molding of the light-transmitting member 200 and the housing 400, thereby limiting the deformation of the housing 400 during injection molding.

[0090] As a specific embodiment, there is no limit to the number of first positioning portions 2100 and second positioning portions 2110, and the number of first positioning portions 2100 and second positioning portions 2110 can be set according to the actual needs of those skilled in the art. The purpose of providing the first positioning portions 2100 and second positioning portions 2110 is to increase the positioning of the housing 400 when the housing 400 and the light-transmitting member 200 are injection-molded together, thereby preventing the housing 400 from tilting after injection molding.

[0091] Preferably, the first positioning portion 2100 and the second positioning portion 2110 are not collinearly disposed on the radially outer side of the light-transmitting member 200 .

[0092] Specifically, the first positioning portion 2100 and the second positioning portion 2110 are respectively arranged on the edges of the light-transmitting member 200, and simultaneously limit the deformation of the shell 400 relative to the light-transmitting member 200 at different positions of the light-transmitting member 200, ensuring the uniformity of the thickness of the surface of the shell 400 wrapped around the light-transmitting member 200, and ensuring more precise positioning of the shell 400.

[0093] In this embodiment, the first positioning portion 2100 and the second positioning portion 2110 are configured to limit the degree of freedom of the housing 400 relative to the light transmitting member 200 in the circumferential direction and / or the axial direction during the injection molding connection.

[0094] Specifically, the first positioning portion 2100 and the second positioning portion 2110 serve as support points when the shell 400 wraps the light-transmitting member 200 for injection molding connection. The first positioning portion 2100 and the second positioning portion 2110 simultaneously apply a certain force to the shell 400 to limit the injection molding deformation of the shell 400.

[0095] In the first embodiment, a first partition 310 is provided between the light-transmitting element 200 and the light-emitting element 100. The first partition 310 separates both the light-emitting element 100 and the light-transmitting element 200, dividing them into multiple light-emitting zones and light-transmitting zones, respectively. In this embodiment, however, the first partition 310 only separates the light incident on the light-emitting element 100. A second partition 410 is provided on the housing 400 to separate the light-transmitting element 200. The first and second partitions 310 and 410 work together to divide the light into corresponding light-transmitting zones.

[0096] Please continue to see Figure 2 In this embodiment, a receiving portion 220 is recessed inwardly on the light-transmitting member 200. The receiving portion 220 is provided to connect to the second partition 410. After the irradiated light strikes the light-transmitting member 200, the second partition 410 separates the irradiated light on the light-transmitting member 200, preventing the irradiated light on the light-transmitting member 200 from interfering with each other.

[0097] Please see again Figure 2In this embodiment, a second partition 410 extends inward from the housing 400. The second partition 410 extends from the inner circumference of the housing 400 toward the light-transmitting member 200 and is inserted into the receiving portion 220. The second partition 410 is configured to divide the light-transmitting member 200 into a plurality of light-transmitting areas. In addition to the first partition 310 provided in the direction of illumination by the light-emitting element 100, the second partition 410 extends from the inner side of the housing 400 toward the light-transmitting member 200. This partition separates the light received by the light-transmitting member 200, preventing interference between the various light-transmitting areas and improving the user experience.

[0098] Specifically, after the light-transmitting member 200 receives the illumination light in the corresponding light-emitting area, the light-transmitting member 200 diffuses the illumination light evenly to the surface of the personal care device. The illumination light on the surface of the light-transmitting member 200 will interfere with each other. By setting the second partition 410, the light-transmitting member 200 is divided into multiple light-transmitting areas, and the illumination light in each light-transmitting area does not interfere with each other, thereby improving the user experience.

[0099] Preferably, the number of light-transmitting areas and the number of light-emitting areas are the same, and the light-transmitting areas and the light-emitting areas are arranged in the same position. The illumination light in the light-emitting areas can be irradiated into the light-transmitting areas accordingly, so that the illumination light on the light-transmitting areas does not interfere with each other, and avoids the illumination light from multiple light-emitting areas irradiating into the same light-transmitting area, so that other light-transmitting areas are not illuminated by the illumination light, thereby causing uneven light reflection on the surface of the personal care device.

[0100] The rest is the same as in Example 1.

[0101] Example 3

[0102] See Figure 1 、 4 5. Unlike Examples 1 and 2, in this embodiment, a light-scattering portion 500 is provided on the illumination light path. The light-scattering portion 500 extends radially outward from the light-isolating member 300 in an illumination direction perpendicular to the illumination light path. By providing the light-scattering portion 500 between the light-isolating member 300 and the light-transmitting member 200, the light emitted from the light-emitting area is evenly scattered onto the corresponding light-transmitting area of ​​the light-transmitting member 200. Furthermore, light-scattering regions 520 corresponding to the light-emitting areas are provided on the light-scattering portion 500, ensuring that the light emitted from the light-scattering regions 520 above the light-scattering portion 500 does not interfere with each other.

[0103] Specifically, the light scattering portion 500 is disposed on the illumination light path, so that the illumination light can first be irradiated onto the light scattering portion 500, and then all the illumination light is scattered on the light-transmitting area by the light scattering portion 500.

[0104] It should be noted that the shape of the light-scattering portion 500 in this embodiment is not limited to Figure 5 The square shape shown in FIG. 3 may also be any other feasible shape, such as a rectangle or a circle.

[0105] Specifically, the light-scattering portion 500 extends toward the outside of the light-emitting area in a direction perpendicular to the illumination direction. The extension length of the light-scattering portion 500 can be set by those skilled in the art according to actual needs. The extension length of the light-scattering portion 500 depends on the size of the light-emitting area. The extension length of the light-scattering portion 500 in the illumination light path must be greater than or equal to the radial length of the light-emitting area, so as to ensure that the illumination light emitted from any position in the light-emitting area can be scattered onto the light-transmitting member 200.

[0106] See Figure 1 In this embodiment, the light-scattering portion 500 is disposed between the light-isolating member 300 and the light-transmitting member 200. The light-scattering portion 500 is spaced a certain distance from the light source to prevent it from crushing the light source. The light-scattering portion 500 is configured to scatter the light from the light source onto the light-transmitting area. By disposing the light-scattering portion 500 between the light-isolating member 300 and the light-transmitting member 200, the light from the light-emitting area is evenly scattered onto the corresponding light-transmitting area of ​​the light-transmitting member 200.

[0107] It is worth mentioning that the illumination light emitted by the luminous area first passes through the light scattering portion 500 and then scatters onto the light-transmitting member 200. The purpose of providing the light scattering portion 500 is to scatter the illumination light more evenly to the light-transmitting area and improve the user experience.

[0108] See Figure 5 In this embodiment, the light-scattering portion 500 is recessed from the radially outer side to the radially inner side to form a plurality of recesses 510. At least a portion of the first partition 310 is disposed within the recesses 510. Adjacent recesses 510 are configured to divide the light-scattering portion 500 into a plurality of light-scattering regions 520. The light-scattering regions 520 are disposed above the corresponding light-emitting regions. The light-scattering regions 520 are configured to scatter the light emitted from the light-emitting regions onto the light-transmitting regions. The light-scattering regions 520 are disposed on the light-scattering portion 500 corresponding to the light-emitting regions to ensure that the light emitted from the light-scattering regions 520 on the light-scattering portion 500 does not interfere with each other.

[0109] Specifically, recesses 510 are provided on each of the four sides of the light-scattering portion 500, recessed toward the center of the portion. Adjacent recesses 510 divide the light-scattering portion 500 into four light-scattering zones 520. Each of these light-scattering zones 520 corresponds to a corresponding light-emitting zone below, scattering the light emitted by the light-emitting zone. By dividing the light-scattering portion 500 into different light-scattering zones 520, the purpose is to prevent the light from each light-scattering zone 520 from interfering with each other when the light-scattering portion 500 scatters the light, ensuring that the light is directed to the corresponding light-transmitting zone.

[0110] As a specific implementation manner, the light-scattering portion 500 is configured as a light-scattering film.

[0111] The rest is the same as in Examples 1 and 2.
