Description

Electric toothbrush bottom lighting effect display structure and electric toothbrush with bottom lighting effect display Technical Field

[0001] The present invention relates to the field of electric toothbrushes, and in particular to a bottom light effect display structure of an electric toothbrush and an electric toothbrush with a bottom light effect display. Background Art

[0002] Many electric toothbrushes have indicator lights located on the mainboard. Users often only see a few lights indicating gear position, battery level, and other information. During use, the position of the brush and the hand holding the brush obstruct the user's view of the indicator lights. If the user wants to switch gears while brushing, they need to stop the brush and switch to view the gear information after leaving their mouth, which is very inconvenient. In addition, as electric toothbrushes become more and more versatile, many are equipped with overvoltage protection. However, the light strips of many existing electric toothbrushes' warning indicators are very narrow. When the user holds the brush during use, the indicator lights on the brush are difficult to see, making it difficult to immediately detect overvoltage conditions. Therefore, the present invention has been developed.

[0003] Summary of the Invention

[0004] The present invention aims to solve the problem that the indicator lights of electric toothbrushes on the market are difficult for users to view and display.

[0005] To this end, the present invention provides a lighting effect display structure at the bottom of an electric toothbrush, which is characterized by comprising:

[0006] A light-guiding inner cylinder, the light-guiding inner cylinder being wrapped around the core of the electric toothbrush, the bottom of the light-guiding inner cylinder extending to form a gradual light-guiding portion, the gradual light-guiding portion gradually becoming thicker along the extension direction and forming a light-collecting surface at the extension end;

[0007] A light display assembly, comprising a light board and a light display element, wherein the light display element is provided on the light board, the light board is electrically connected to the control main board of the electric toothbrush, and the light-emitting end of the light display element faces the light-collecting surface;

[0008] A light-transmitting outer cylinder at least covers the light-guiding inner cylinder and the light display assembly.

[0009] Preferably, the light-transmitting inner cylinder is implemented as a light-transmitting injection-molded structure with a light-guiding agent added thereto.

[0010] Preferably, the light board is an annular light board, and the light display elements are multiple, and the multiple light display elements are installed on the annular light board and arranged around the through hole of the annular light board.

[0011] Preferably, the gradual light-guiding portion is a cylindrical structure, and the cylindrical wall gradually becomes thicker as it extends outward.

[0012] Preferably, the light-emitting end positions of the plurality of light display elements correspond to the light-collecting surface of the gradient light-guiding portion.

[0013] Preferably, the light-transmitting outer cylinder includes a light-transmitting cylinder body and a bottom cover, the bottom of the light-transmitting cylinder body is provided with a port, and the bottom cover is arranged on the port.

[0014] Preferably, the bottom cover is implemented as a light-proof structure.

[0015] Preferably, a stepped structure is formed on the bottom of the light-transmitting cylinder, and the bottom cover is sleeved on the stepped structure.

[0016] The above technical solutions alone or in combination exhibit the following beneficial effects:

[0017] By forming a gradient light-guiding portion at the bottom of the light-guiding inner tube, the light emitted by the light-emitting end of the light display component is collected by the light-collecting surface and guided to the light-guiding inner tube (based on the principle of total reflection and refraction when light is transmitted in different media). The light effect presents a gradient light effect of light and dark, making it easier for users to perceive the changes in the indicator light signal of the light display component.

[0018] Electroplating or laser texturing is used to form a textured surface on the light-transmitting outer tube, which, combined with the light-guiding effect of the light-guiding inner tube, presents a more beautiful lighting effect.

[0019] Implementing the light-guiding inner tube as a translucent injection-molded structure with light-guiding agent added can increase the scattering and transmission of light, shielding the light source and the glare light source while making the light softer, more beautiful and elegant, achieving a comfortable effect of translucent and opaque.

[0020] There are multiple light display elements on the light display assembly, which are arranged in a circle to form an aperture, making it convenient for users to observe at different holding angles.

[0021] The bottom cover is implemented as a light-proof structure to prevent the bottom light from being exposed and causing interference. When the user uses the electric toothbrush, he can directly observe the barrel body with peripheral vision or the reflection of a table mirror.

[0022] The present invention also provides an electric toothbrush with a bottom lighting effect display, which is characterized by comprising the above-mentioned electric toothbrush bottom lighting effect display structure.

[0023] Preferably, the body of the electric toothbrush is implemented as a grip section and a light display section, the light display section is located at the bottom of the body, and at least the light display assembly and the gradient light guide portion are located in the light display section.

[0024] The above technical solutions have the following beneficial effects:

[0025] By setting a light-guiding inner cylinder in the electric toothbrush and forming a gradient light-guiding portion at the bottom of the light-guiding inner cylinder, the light emitted by the light-emitting end of the light display component is collected by the light-collecting surface and guided to the light-guiding inner cylinder (based on the principle of total reflection and refraction of light transmitted in different media). The light effect presents a gradient light effect of light and dark, which makes it easy for users to perceive the changes in the indicator light signal of the light display component.

[0026] The light display assembly and the corresponding gradient light guide portion are arranged at the bottom of the electric toothbrush body, avoiding the grip section where the hand holds it, so that the indicator light information feedback can be viewed more conveniently without being blocked by the user's hand.

[0027] Electroplating or laser texturing is used to form a textured surface on the light-transmitting outer tube, which, combined with the light-guiding effect of the light-guiding inner tube, presents a more beautiful lighting effect.

[0028] Implementing the light-guiding inner tube as a translucent injection-molded structure with light-guiding agent added can increase the scattering and transmission of light, shielding the light source and the glare light source while making the light softer, more beautiful and elegant, achieving a comfortable effect of translucent and opaque.

[0029] There are multiple light display elements on the light display assembly, which are arranged in a circle to form an aperture, making it convenient for users to observe at different holding angles.

The basic principles of the present invention defined in the following description may be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

Therefore, the above terms should not be understood as limiting the present invention.

[0041] Example 1:

[0042] Referring to Figures 1 to 7 , this embodiment provides a lighting effect display structure at the bottom of an electric toothbrush, comprising a light-guiding inner tube 2, a light-display assembly 4, and a light-transmitting outer tube 3. The light-guiding inner tube 2 encases the electric toothbrush's movement. The bottom of the light-guiding inner tube 2 extends to form a gradient light-guiding portion 21, which gradually thickens along its extension direction and forms a light-collecting surface 210 at its distal end. The light-display assembly 4 includes a light board 41 and a light-display element 42, which is mounted on the light board 41 and electrically connected to the electric toothbrush's control board 13 via a connecting wire 43. The light-emitting end of the light-display element 42 faces the light-collecting surface 210. The light-transmitting outer tube 3 at least encases the light-guiding inner tube 2 and the light-display assembly 4. By forming a gradient light-guiding portion 21 at the bottom of the light-guiding inner cylinder 2, the light emitted by the light-emitting end of the light display component 4 is collected by the light-collecting surface 210 and guided to the light-guiding inner cylinder 2 (according to the principle of total reflection and refraction of light transmitted in different media). The light effect presents a gradient light effect of light and dark, which makes it easy for users to perceive the changes in the indicator light signal of the light display component 4. While brushing their teeth, users can check the working mode of the electric toothbrush, as well as information such as pressure alarm through peripheral vision or mirror reflection.

[0043] The above solutions are essential for implementing this embodiment, and are further described in detail below with reference to the accompanying drawings and specific implementation methods:

[0044] As is well known, an electric toothbrush consists of a motor, a brush head, and a power supply. The rapid rotation, oscillation, or vibration of the motor causes the brush head to vibrate, oscillate, or rotate at high frequencies, breaking down the toothpaste into fine foam to clean the spaces between teeth. This example does not elaborate on the working principles of an electric toothbrush.

[0045] It should be noted that this embodiment can combine the total reflection and refraction principles of light to enhance the light-guiding effect of the gradient light-guiding portion 21. Total internal reflection, also known as total internal reflection, refers to the phenomenon that when light is emitted from a denser medium (i.e., the medium in which the refractive index of light is large) to an interface of a less dense medium (i.e., the medium in which the refractive index of light is small), all of it is reflected back into the original medium. Therefore, the material selection for the gradient light-guiding portion 21 can be selected from PC or PP transparent materials with a refractive index greater than that of air, so that a small amount of light on the collecting surface at the interface in contact with air is refracted into the air, and a large amount is totally reflected back to the original medium (i.e., the gradient light-guiding portion 21), realizing light collection, thereby achieving a light effect with gradual brightness change from thick to thin in the gradient light-guiding portion 21.

[0046] Furthermore, the light-guiding inner tube 2 can be injection-molded using an injection molding material with a light-guiding agent added to facilitate light display. This injection molding imparts a certain degree of strength to the overall body and also provides protection. For example, PP plastic with a light-guiding agent can be injection-molded. It should be noted that light-guiding agents include those commonly referred to in the market as brighteners, levelers, homogenizers, and light diffusers. Their purpose is to increase light scattering and transmission, shielding light sources and glare while also making the entire light-guiding inner tube 2 emit a softer, more aesthetically pleasing, and elegant light, achieving a comfortable, opaque, and light-transmitting effect. Examples of light diffusers include acrylic, styrene, and acrylic resin-based light diffusers.

[0047] Furthermore, the material of the light-transmitting outer cylinder 3 can be one of polycarbonate, polymethyl methacrylate and polypropylene, and can be combined with electroplating or laser texturing to achieve beautiful surface textures, and then combined with the light-guiding effect of the light-guiding inner cylinder 2 to present a more beautiful lighting effect.

[0048] Furthermore, referring to Figures 1, 2, and 3, the body structure of the electric toothbrush is cylindrical for easy gripping, so that the user can perceive the changes in the indicator light information at different gripping angles. A preferred implementation of this embodiment is to implement the light board 41 as a ring-shaped light board, and implement multiple light display elements 42. The multiple light display elements 42 are installed on the ring-shaped light board and arranged around the through-holes of the ring-shaped light board. Preferably, the light display elements 42 use LED lamp beads, and the light board 41 is an integrated circuit board, which is a structural mounting carrier for the LED lamp beads and is electrically connected to the control main board 13 of the electric toothbrush.

[0049] As shown above, referring to Figures 3 and 4 in conjunction with Figures 5, 6, and 7, the gradual light guide portion 21 is a cylindrical structure, with the cylindrical wall gradually thickening as it extends outward, forming an annular light-collecting surface 210. Furthermore, the light-emitting ends of the multiple light display elements 42 correspond to the light-collecting surface 210 of the gradual light guide portion 21, that is, the light from the LED beads is irradiated by the light-collecting surface 210.

[0050] Further, referring to Figure 2, to prevent light leakage from the bottom from affecting the observation of the indicator light signal, the light-transmitting outer cylinder 3 comprises a light-transmitting cylinder body 31 and a bottom cover 32. The bottom of the light-transmitting cylinder body 31 has a port, and the bottom cover 32 is located at the port. Specifically, the bottom cover 32 is implemented as a light-proof structure. The bottom of the light-transmitting cylinder body 31 is formed with a stepped structure 310, and the bottom cover 32 is sleeved on the stepped structure 310. Alternatively, the stepped structure 310 can be threaded, and the inner wall of the bottom cover 32 can be provided with matching threads to form a threaded connection between the two.

[0051] The beneficial effects of this embodiment are:

[0052] By forming a gradient light-guiding portion 21 at the bottom of the light-guiding inner tube 2, the light emitted by the light-emitting end of the light display component 4 is collected by the light-collecting surface 210 and guided to the light-guiding inner tube 2 (according to the principle of total reflection and refraction of light transmitted in different media), and the light effect presents a gradient light effect of light and dark, which makes it easier for users to perceive the changes in the indicator light signal of the light display component 4.

[0053] The light-transmitting outer cylinder 3 is provided with a textured surface by adopting processes such as electroplating or laser texturing, which cooperates with the light-guiding effect of the light-guiding inner cylinder 2 to present a more beautiful lighting effect.

[0054] Implementing the light-guiding inner tube 2 as a translucent injection-molded structure with light-guiding agent added can increase the scattering and transmission of light, shielding the light source and the glare light source while making the light softer, more beautiful and elegant, achieving a comfortable effect of translucent and opaque.

[0055] There are multiple light display elements 42 on the light display assembly 4, and they are arranged in a circle to form an aperture, which is convenient for users to observe at different holding angles.

[0056] The bottom cover 32 is implemented as a light-proof structure to prevent the bottom light from being exposed and causing interference. When the user uses the electric toothbrush, he can directly observe the barrel body with peripheral vision or the reflection of a table mirror.

[0057] Example 2:

[0058] Please refer to Figures 1 to 7. This embodiment also provides an electric toothbrush with a bottom lighting effect display, including the electric toothbrush bottom lighting effect display structure described in Example 1.

[0059] Specifically, referring to Figures 5 to 7 , the lighting effect display structure at the bottom of the electric toothbrush includes a light-guiding inner tube 2, a light-display assembly 4, and a light-transmitting outer tube 3. The light-guiding inner tube 2 encases the electric toothbrush's movement. The bottom of the light-guiding inner tube 2 extends to form a gradient light-guiding portion 21, which gradually thickens along its extension direction and forms a light-collecting surface 210 at the end. The light-display assembly 4 includes a light board 41 and a light-display element 42, which is mounted on the light board 41. The light board 41 is electrically connected to the electric toothbrush's control board 13 via a connecting wire 43, with the light-emitting end of the light-display element 42 facing the light-collecting surface 210. The light-transmitting outer tube 3 at least encloses the light-guiding inner tube 2 and the light-display assembly 4.

[0060] As is well known, an electric toothbrush consists of a motor, a brush head, and a power supply. The rapid rotation or vibration of the motor causes the brush head to vibrate or rotate at a high frequency, breaking down the toothpaste into fine foam to clean the spaces between teeth. This example does not elaborate on the working principles of an electric toothbrush.

[0061] Furthermore, the light-guiding inner tube 2 can be injection-molded using an injection molding material with a light-guiding agent added to facilitate light display. This injection molding imparts a certain degree of strength to the overall body and also provides protection. For example, PP plastic with a light-guiding agent can be injection-molded. It should be noted that light-guiding agents include those commonly referred to in the market as brighteners, levelers, homogenizers, and light diffusers. Their purpose is to increase light scattering and transmission, shielding light sources and glare while also making the entire light-guiding inner tube 2 emit a softer, more aesthetically pleasing, and elegant light, achieving a comfortable, opaque, and light-transmitting effect. Examples of light diffusers include acrylic, styrene, and acrylic resin-based light diffusers.

[0062] Furthermore, the material of the light-transmitting outer cylinder 3 can be one of polycarbonate, polymethyl methacrylate and polypropylene, and can be combined with electroplating or laser texturing to achieve beautiful surface textures, and then combined with the light-guiding effect of the light-guiding inner cylinder 2 to present a more beautiful lighting effect.

[0063] Furthermore, referring to Figures 1, 2, and 3, the body structure of the electric toothbrush is cylindrical for easy gripping, so that the user can perceive the changes in the indicator light information at different gripping angles. A preferred implementation of this embodiment is to implement the light board 41 as a ring-shaped light board, and implement multiple light display elements 42. The multiple light display elements 42 are installed on the ring-shaped light board and arranged around the through-holes of the ring-shaped light board. Preferably, the light display elements 42 use LED lamp beads, and the light board 41 is an integrated circuit board, which is a structural mounting carrier for the LED lamp beads and is electrically connected to the control main board 13 of the electric toothbrush.

[0064] As shown above, referring to Figures 3 and 4 in conjunction with Figures 5, 6, and 7, the gradual light guide portion 21 is a cylindrical structure, with the cylindrical wall gradually thickening as it extends outward, forming an annular light-collecting surface 210. Furthermore, the light-emitting ends of the multiple light display elements 42 correspond to the light-collecting surface 210 of the gradual light guide portion 21, that is, the light from the LED beads is irradiated by the light-collecting surface 210.

[0065] Further, referring to Figure 2, to prevent light leakage from the bottom from affecting the observation of the indicator light signal, the light-transmitting outer cylinder 3 comprises a light-transmitting cylinder body 31 and a bottom cover 32. The bottom of the light-transmitting cylinder body 31 has a port, and the bottom cover 32 is located at the port. Specifically, the bottom cover 32 is implemented as a light-proof structure. The bottom of the light-transmitting cylinder body 31 is formed with a stepped structure 310, and the bottom cover 32 is sleeved on the stepped structure 310. Alternatively, the stepped structure 310 can be threaded, and the inner wall of the bottom cover 32 can be provided with matching threads to form a threaded connection between the two.

[0066] Furthermore, to facilitate the user's observation of the indicator light changes while holding the electric toothbrush, the body of the electric toothbrush is implemented as a grip section 11 and a light display section 12. The light display section 12 is located at the bottom of the body, and at least the light display assembly 4 and the gradient light guide portion 21 are located in the light display section 12. In this way, the user can check the indicator light information in a timely manner through peripheral vision or the reflection of a table mirror while brushing their teeth.

[0067] The above technical solutions have the following beneficial effects:

[0068] By setting a light-guiding inner cylinder 2 in the electric toothbrush, a gradient light-guiding portion 21 is formed at the bottom of the light-guiding inner cylinder 2. The light emitted by the light-emitting end of the light display component 4 is collected by the light-collecting surface 210 and guided to the light-guiding inner cylinder 2 (according to the principle of total reflection and refraction of light transmitted in different media). The light effect presents a gradient light effect of light and dark, which makes it easy for users to perceive the changes in the indicator light signal of the light display component 4.

[0069] The light display assembly 4 and the corresponding gradient light guide portion 21 are arranged at the bottom of the electric toothbrush body, avoiding the grip section 11 held by the hand, so that the indicator light information feedback can be viewed more conveniently without being blocked by the user's hand.

[0070] The light-transmitting outer cylinder 3 is provided with a textured surface by adopting processes such as electroplating or laser texturing, which cooperates with the light-guiding effect of the light-guiding inner cylinder 2 to present a more beautiful lighting effect.

[0071] Implementing the light-guiding inner tube 2 as a translucent injection-molded structure with light-guiding agent added can increase the scattering and transmission of light, shielding the light source and the glare light source while making the light softer, more beautiful and elegant, achieving a comfortable effect of translucent and opaque.

[0072] There are multiple light display elements 42 on the light display assembly 4, and they are arranged in a circle to form an aperture, which is convenient for users to observe at different holding angles.

[0073] The bottom cover 32 is implemented as a light-proof structure to prevent the bottom light from being exposed and causing interference. When the user uses the electric toothbrush, he can directly observe the barrel body with peripheral vision or the reflection of a table mirror.
