Description

Technical Field

[0001] This utility model relates to the field of electric toothbrushes, and more particularly to an electric toothbrush. Background Technology

[0002] Electric toothbrushes use a sonic motor or other drive device to automatically swing or vibrate the brush head, and indicator lights on the device body indicate the current speed or battery level.

[0003] Indicator lights on devices are typically dot lights, meaning there are circular holes on the casing that correspond to the number of LEDs to indicate different statuses. The limitations of these dot light sources, due to the need for multiple status indicators, forced the creation of multiple dot light positions on the toothbrush casing, resulting in a high degree of homogenization in the lighting of electric toothbrushes on the market and a subpar user experience. Utility Model Content

[0004] This invention provides an electric toothbrush designed to address the shortcomings of existing electric toothbrushes in terms of user experience.

[0005] According to an embodiment of this application, an electric toothbrush is provided, including a housing, a light-emitting part, and a light-guiding part. The light-emitting part is placed inside the housing, and the light-guiding part is positioned on one side of the housing corresponding to the light-emitting direction of the light-emitting part. A light-guiding groove is formed on the housing, and one end of the light-guiding part away from the light-emitting part is placed in the light-guiding groove. The light-guiding part includes a light-guiding post, which is disposed corresponding to the light-emitting area of ​​the light-emitting part. The light-guiding post has a strip-shaped structure and is embedded in the light-guiding groove.

[0006] Preferably, the light-emitting part includes a circuit board and a light strip or multiple LED beads, the light strip or multiple LED beads being arranged along the axial direction of the housing; the light guide post is arranged in the same direction as the light strip or multiple LED beads.

[0009] Preferably, the first shock absorber includes a mounting part and a sealing part. The mounting part is sleeved and pre-tightened to one end of the motor. The output shaft of the motor extends outward through the sealing part and the housing. The sealing part includes an inner ring and an outer ring. The inner ring is sleeved on the outer periphery of the output shaft. The outer ring has at least one outwardly protruding arch, which abuts against the inner side of the housing.

[0010] Preferably, a cavity is formed between the inner ring and the outer ring.

[0011] Preferably, the inner ring has an inwardly protruding step on its inner side at the end near the motor.

[0012] Preferably, the second shock-absorbing block is positioned at one end of the bracket, and the battery is positioned at the other end; the light-emitting part is positioned on the side of the bracket.

[0014] Preferably, the light guide post is made of a light-transmitting soft rubber material.

[0015] Compared with the prior art, the electric toothbrush provided by this utility model has the following beneficial effects:

[0016] 1. By setting a light guide groove on the outer shell, the light guide column passes through the light guide groove, and the light-emitting part emits a strip light source which passes through the light guide groove and is emitted outward, so that the electric toothbrush of this application can form a strip light-emitting effect. It utilizes the rich light emission mode and display effect of the strip light source, which has a richer visual effect and improves the user experience during use. It abandons the single effect of the current dot matrix light emission, so that the electric toothbrush of this application can not only realize the prompt effect when using or charging, but also make the product have a better visual effect during use.

[0017] 2. By setting the first and second shock absorbers and installing them at both ends of the motor, the motor does not directly contact the outer casing.

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0036] It should also be understood that the terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention. As used in this specification and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms unless the context clearly indicates otherwise.

[0037] It should also be further understood that the term "and / or" as used in this specification and the appended claims refers to any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0038] Please combine Figure 1 , Figure 2 and Figure 3 The first embodiment of this utility model discloses an electric toothbrush, including a shell 1, a light-emitting part 2, and a light-guiding part 3. The light-emitting part 2 is placed inside the shell 1, and the light-guiding part 3 is positioned on one side of the shell 1 corresponding to the light-emitting direction of the light-emitting part 2.

[0039] Specifically, a light guide groove 11 is provided on the outer shell 1 (e.g., Figure 3 As shown in the figure, the light guide part 3 is placed in the light guide groove 11 at the end away from the light-emitting part 2. The light guide part 3 passes through the light guide groove 11 and is exposed outside the housing 1, so that the light emitted by the light-emitting part 2 can be uniformly emitted outside the housing 1 after passing through the light guide part 3.

[0040] like Figure 3 As shown, the light guide portion 3 includes a positioning pad 31 and a light guide post 32, with the positioning pad 31 abutting against the inner side of the outer casing 1 (specifically as shown in the figure). Figure 5 As shown in the diagram, the light guide post 32 is disposed corresponding to the light-emitting area of ​​the light-emitting part 2. The light guide post 32 is connected to or integrally formed with the positioning pad 31. The light guide post 32 has a strip-shaped structure and protrudes from the surface of the positioning pad 31. The light guide post 32 is embedded in the light guide groove 11.

[0041] It is understood that in this embodiment, the positioning pad 31 and the light guide post 32 are integrally molded, and both are made of a light-transmitting soft rubber material, such as a semi-transparent TPE material. The light emitted by the light-emitting part 2 passes through the positioning pad 31 and the light guide post 32 sequentially and finally shines outward. Alternatively, in other embodiments, the positioning pad 31 and the light guide post 32 are fixedly connected. For example, the positioning pad 31 has a through groove in the area corresponding to the light guide post 32, and the light guide post 32 is embedded in the through groove and fixed with adhesive. In this case, the light-emitting part 2 only needs to pass through the light guide post 32.

[0042] It is understood that the light guide post 32 can also be directly embedded and positioned in the light guide groove 11. After the light guide post 32 is embedded, it can be fixed by dispensing glue or by clamping the light guide groove 11 directly. That is, there is no need to set the positioning pad 31. The light-emitting part 2 can be directly aligned with the light guide post 32 to emit light, and the light emission effect of the strip light source can also be achieved.

[0043] Please continue to combine Figure 1 and Figure 2 The light-emitting part 2 includes a circuit board 21 and a plurality of lamp beads 22. The plurality of lamp beads 22 are arranged along the axial direction of the outer shell 1. The light guide column 32 is arranged in the same direction as the plurality of lamp beads 22, so that when the electric toothbrush of this application is placed vertically on the table, the strip-shaped light guide column 32 is aligned with the axial direction of the outer shell 1, forming a vertical strip structure with the same placement posture as the electric toothbrush.

[0044] It is understood that in this embodiment, the light-emitting part 2 is a strip light source for emitting light. For example, it can use multiple linearly arranged LED beads 22, or it can use an integrated light strip. That is, in other embodiments, multiple LED beads 22 can be directly replaced with a single light strip. The light strip is arranged along the axial direction of the housing 1, and the above-mentioned strip light-emitting structure can also be formed, as long as the light guide column 32 can emit light. There is no limitation here.

[0045] It is understood that in this embodiment, the light-emitting part 2 can employ multiple light-emitting methods to indicate different toothbrush usage states. For example, different light-emitting colors can indicate different motor speeds, or multiple flashing modes can be set to create light-emitting effects such as colored or monochrome flowing lights or breathing lights. Because a strip light source is used, the light-emitting part 2 of this application can have more light-emitting methods, resulting in a richer visual experience and enhancing the user experience; simultaneously, a single strip-shaped light-emitting part can represent multiple different toothbrush usage states.

[0046] Please combine Figure 4 and Figure 5The electric toothbrush of this application also includes a motor 4, a shock-absorbing module 5, and a bracket 6 located inside the outer shell 1. The shock-absorbing module 5 includes a first shock-absorbing block 51 and a second shock-absorbing block 52 disposed at both ends of the motor 4. The first shock-absorbing block 51 is located between the outer shell 1 and the motor 4, and the second shock-absorbing block 52 is located between the bracket 6 and the motor 4, so that the shock-absorbing module 5 is provided on the fixed structure of the motor 4 to reduce the working vibration and noise of the motor 4.

[0047] It is understood that the first damping block 51 and the second damping block 52 can be made of TPU (thermoplastic polyurethane), silicone or rubber, or other common soft damping materials.

[0048] Please combine Figure 5 and Figure 6 The first shock absorber 51 includes a mounting part 511 and a sealing part 512. The mounting part 511 is sleeved and pre-tightened to one end of the motor 4. The output shaft 100 of the motor 4 extends outward through the sealing part 512 and the outer casing 1.

[0049] The sealing part 512 includes an inner ring 5121 and an outer ring 5122. The inner ring 5121 is sleeved on the outer periphery of the output shaft 100, and the outer ring 5122 is provided with an outwardly protruding arch a, which abuts against the inner side of the outer casing 1.

[0050] like Figure 5 As shown, the outer casing 1 has an annular extension arm 12 at the position corresponding to the sealing part 512. After the sealing part 512 is inserted into the extension arm 12, it is exposed on the surface of the outer casing 1. The arch a of the outer ring 5122 is interference-fitted with the extension arm 12 to achieve pre-tight sealing. The arc surface of the arch a can facilitate the sealing part 512 to pass through the extension arm 12 and be pre-tightly sealed with the inner wall surface of the extension arm 12.

[0051] It is understandable that the arch 'a' can be configured as a multi-layered structure, that is, multiple concentric arches 'a' in the circumferential direction, which can further enhance the sealing and fastening effect. For example... Figure 6 As shown in the illustration, in this embodiment, the arch a has two layers.

[0052] like Figure 5 As shown, the inner ring 5121 is sleeved on the outer periphery of the output shaft 100, and the inner ring 5121 is used to seal the area where the output shaft 100 is located. Since the sealing part 512 is made of soft rubber, the inner ring 5121 seals and wraps around the outer periphery of the output shaft 100 based on the deformation characteristics of the soft rubber, thus forming a sealing and waterproof effect.

[0053] like Figure 6As shown, a cavity b is formed between the inner ring 5121 and the outer ring 5122, which gives the sealing part 512 a larger deformable space, which can better cope with the high-frequency reciprocating rotation or vibration working environment of the output shaft 100, and improve the sealing and waterproofing effect on the housing 1 and the output shaft 100.

[0054] The inner ring 5121 also has an inwardly protruding step 101 on the inner side near the end of the motor 4, and the step 101 is interference-fitted with the output shaft 100.

[0055] Please continue reading. Figure 4 The second shock absorber 52 is positioned at one end of the bracket 6, and the battery 102 is positioned at the other end. The circuit board 21 is positioned on the side of the bracket 6, and the bracket 6 is positioned inside the outer casing 1.

[0056] The bracket 6 has a cup-shaped structure 103 at the position of the second shock absorber 52. The second shock absorber 52 is positioned inside the cup-shaped structure 103, and the tail side of the cup-shaped structure 103 and the side of the second shock absorber 52 are hollowed out, so that one end of the motor 4 is exposed, which facilitates the heat dissipation of the motor 4.

[0057] Compared with the prior art, the electric toothbrush provided by this utility model has the following beneficial effects:

[0058] 1. By setting a light guide groove on the outer shell, the light guide column passes through the light guide groove, and the light-emitting part emits a strip light source which passes through the light guide groove and is emitted outward, so that the electric toothbrush of this application can form a strip light-emitting effect. It utilizes the rich light emission mode and display effect of the strip light source, which has a richer visual effect and improves the user experience during use. It abandons the single effect of the current dot matrix light emission, so that the electric toothbrush of this application can not only realize the prompt effect when using or charging, but also make the product have a better visual effect during use.

[0059] 2. By setting the first and second shock absorbers and installing them at both ends of the motor, the motor does not directly contact the outer casing. Based on the action of the first and second shock absorbers, the vibration and noise of the electric toothbrush during operation are reduced, thus improving the user's practical experience.

[0060] 3. By setting an installation part and a sealing part on the first shock absorber, the inner ring of the sealing part seals the output shaft, and the outer ring is provided with a raised arch. The surface of the arch is an arc structure, so the outer ring can improve the pre-tight seal with the inner side of the housing. At the same time, the arc surface of the arch can facilitate the installation of the first shock absorber on the housing.

[0061] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
