[0040] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0041] See Figures 1 to 6 As shown, an embodiment of the first aspect of this application discloses an electric toothbrush, including a drive component 300, an inner shaft component 200, a mounting component 400, and an elastic component 500.

[0042] Specifically, the drive component 300 is used to drive the inner shaft component 200 to rotate; the mounting component 400 is used to set the brush head component 420; the elastic component 500 is disposed between the mounting component 400 and the inner shaft component 200; the inner shaft component 200 is used to drive the elastic component 500 to swing, and then drive the mounting component 400 to rotate through the elastic component 500.

[0043] In the embodiments of this application, the inner shaft component 200 rotates to drive the elastic component 500 to swing, and the swing of the elastic component 500 drives the mounting component 400 to rotate. This design converts the power of the driving component 300 into the rotational power of the mounting component 400. At the same time, during the power transmission process, the elastic component 500 not only plays a role in buffering, shock absorption and noise reduction, but also reduces the impact of collisions, vibrations and unstable factors on power transmission, ensuring that the inner shaft component 200 can transmit power relatively stably. Ultimately, the brush head component 420 on the mounting component 400 rotates at a relatively stable speed and force, maintaining a stable cleaning effect and reducing noise during operation.

[0044] It should be noted that in some embodiments, this application achieves coordinated operation by combining the mounting component 400, the inner shaft component 200, and the elastic component 500 into a three-in-one linkage drive mechanism. The output shaft of the drive component 300 drives the inner shaft component 200 to oscillate left and right, causing the elastic component 500 to swing, which in turn drives the mounting component 400 to rotate left and right, thus rotating the bristles. This new structure also exhibits better noise reduction during operation. Compared to some complex transmission systems, the structure of the elastic component 500 oscillating to rotate the brush head is relatively simple. While achieving brush head rotation, it effectively reduces energy loss and improves energy utilization efficiency, allowing the toothbrush to work continuously for a longer period with the same amount of electricity, combining energy saving and high efficiency. Due to the buffering effect of the elastic component 500 oscillation, the external force on the brush head during rotation is relatively uniform, preventing the bristles from bending or breaking due to excessive force, thus extending the bristle lifespan and allowing the brush head to maintain good cleaning performance for a longer period.

[0045] It is understood that in some embodiments, the electric toothbrush also includes a housing component 100, which provides a base for mounting and fixing the various components of the electric toothbrush, enabling them to maintain a relatively stable positional relationship and form a complete product with a specific shape and structure. In some embodiments, it can organically combine components such as the drive component 300, inner shaft component 200, mounting component 400, and battery to ensure that the electric toothbrush will not generate abnormal vibration or noise due to loose components during operation, thus ensuring the stability and reliability of the overall structure.

[0046] In some embodiments, refer to Figure 1 and Figure 4 The shape and size of the housing component 100 are typically designed according to ergonomic principles to provide a comfortable grip and facilitate user operation. Furthermore, the housing component 100 of the electric toothbrush is also designed with anti-slip textures or raised structures to prevent slippage due to wet hands or improper force during use. In addition, buttons, switches, and other operating components are also arranged on the housing for easy user operation, enabling functions such as switching brushing modes, starting, and stopping.

[0047] In some embodiments, the drive component 300 is the power source for the electric toothbrush. It converts electrical energy into mechanical energy, generates power through high-speed rotation, and, in conjunction with the transmission mechanism, provides rotational energy to the brush head, enabling the brush head to move at a certain frequency and amplitude, thereby achieving the function of cleaning teeth.

[0048] In some embodiments, the mounting component 400 is rotatably mounted on the housing component 100. The structure of the housing component 100 limits the positioning of the mounting component 400, and the rotatable mounting method allows the mounting component 400 to rotate under external force. The mounting component 400 is used to mount a brush head component 420, such as a toothbrush head or other commonly used structure. Therefore, when the mounting component 400 rotates, it can drive the brush head to rotate synchronously, thereby achieving the function of cleaning teeth.

[0049] It should be understood that the drive motor, through a suitable transmission mechanism, enables the mounting component 400 to rotate smoothly around its rotational axis, thereby allowing the brush or brush head mounted on the mounting component 400 to perform the function of cleaning teeth. In some embodiments of this application, the inner shaft component 200 and the elastic component 500 are configured as a transmission mechanism, enabling the drive component 300 to drive the mounting component 400 to rotate via the transmission mechanism. Specifically, the rotation of the inner shaft component 200 causes the elastic component 500 to oscillate. While oscillating, the elastic component 500 can both drive the mounting component 400 to rotate and utilize its own elastic deformation to achieve expansion and contraction, absorbing the vibration transmitted by the mounting component 400 and / or the inner shaft component 200, thereby reducing the impact of vibration and instability on the cleaning effect. Furthermore, the oscillation of the elastic component 500 makes the power transmission more stable, thus reducing the noise generated during cleaning. In some embodiments, the drive component 300 is directly connected to the inner shaft component 200, and the drive component 300 directly drives the inner shaft component 200 to rotate. In other embodiments, the drive component 300 and the inner shaft component 200 are indirectly connected through a transmission mechanism or a connecting structure. By defining the structure of the transmission mechanism or connecting structure, the transmission mechanism or connecting structure is equipped with the ability to convert the driving force of the drive component 300 into driving the inner shaft component 200 to rotate, thereby achieving the effect of power transmission.

[0050] The following will combine Figures 1 to 6 The electric toothbrush disclosed in the embodiments of this application will be explained and described in detail.

[0051] Understandably, in combination Figures 1 to 6 The elastic member 500 has a first end and a second end opposite to each other in the extension direction. The first end of the elastic member 500 is disposed on the inner shaft member 200, and the second end of the elastic member 500 is disposed on the mounting member 400.

[0052] To make the transmission structure design simpler, refer to Figure 2 , Figure 3 and Figure 5 In some embodiments of this application, the first end of the elastic member 500 is disposed in the circumferential direction of the inner shaft member 200. It can be understood that the driving member 300 can drive the inner shaft member 200 to rotate, and the rotation of the inner shaft member 200 will cause the elastic member 500 disposed in the circumferential direction to swing directly, and then convert the rotation of the elastic member 500 into the power for the rotation of the mounting member 400, thereby achieving the effect of transmission.

[0053] Furthermore, in some embodiments of this application, the mounting component 400 has a first surface 401 and a second surface 402. The first surface 401 is used to mount the brush head component 420, and the second surface 402 is opposite to the first surface 401. The second end of the elastic component 500 is eccentrically mounted on the second surface 402.

[0054] It is understandable that, with the first end of the elastic component 500 positioned circumferentially on the inner shaft component 200, the rotation of the inner shaft component 200 will cause the first end of the elastic component 500 to move in a circular motion around the axis of the inner shaft component 200, causing the elastic component 500 to swing around its first end as a base point. The second end of the elastic component 500 is eccentrically positioned on the second surface 402 of the mounting component 400. Therefore, the swinging of the elastic component 500 will cause the mounting component 400 to rotate, thus achieving the effect of power transmission.

[0055] It should be understood that in order to make the power transmission effect of the elastic component 500 more stable, the design and installation method of the mounting structure used to fix the two ends of the elastic component 500 are the key to achieving the above functions.

[0056] In some embodiments of this application, the inner shaft component 200 is provided with a first mounting portion 210. The first mounting portion 210 is used to mount the first end of the elastic component 500. The first mounting portion 210 is used to swing as a swing arm as the inner shaft component 200 rotates, thereby driving the elastic component 500 to swing. It can be understood that the first mounting portion 210 not only serves to fix the first end of the elastic component 500, but also acts as a swing arm, so that even if the elastic component 500 deforms during transmission, the stability of the transmission can be guaranteed based on the fixing and lever arm effect of the first mounting portion 210.

[0057] It should be noted that, based on the fact that the first mounting part 210 can perform the above-mentioned functions, different embodiments can be achieved by adjusting the setting position.

[0058] Based on this, in some embodiments, further reference is made to Figure 2 , Figure 3 and Figure 5 The first mounting part 210 is disposed on the circumferential sidewall of the inner shaft component 200. It can be understood that, based on the arrangement of the first mounting part 210, the first end of the elastic component 500 can be smoothly fixed on the circumferential sidewall of the inner shaft component 200. At the same time, the first mounting part 210 swings with the rotation of the inner shaft component 200 and drives the elastic component 500 to swing.

[0059] Furthermore, a first mounting space 211 with a first preset depth is formed on the first mounting portion 210, and the first end of the elastic member 500 is disposed within the first mounting space 211. It can be understood that by utilizing the first mounting space 211 with a certain depth to accommodate the elastic member 500 of a certain length, the first mounting portion 210 can better exert its lever arm function. The first mounting space 211 with the first preset depth can reduce the swaying of the elastic member 500, effectively improving the buffering and adjustment function of the elastic member 500, and further improving the stability of the rotation and cleaning force of the brush head component 420.

[0060] In some embodiments, the first mounting portion 210 is disposed on the end of the inner shaft component 200. It is understood that because the first mounting portion 210 can function as both a fixing and a swing arm, its position can be flexibly adjusted. When the inner shaft component 200 rotates, it drives the first mounting portion 210 to swing, thus acting as a lever arm to synchronously drive the elastic component 500 disposed on the first mounting portion 210 to swing, achieving a transmission effect.

[0061] In some embodiments of this application, reference is made to Figure 2 , Figure 3 and Figure 5 A second mounting portion 410 is provided on the second surface 402, and the second mounting portion 410 forms a second mounting space 411 with a second preset depth. The second end of the elastic member 500 is disposed within the second mounting space 411. It can be understood that the second mounting space 411 not only serves to fix the second end of the elastic member 500, but also, because the second mounting space 411 has a certain depth to accommodate a certain length of elastic member 500, it reduces the shaking of the elastic member 500, effectively improves the buffering and adjustment function of the elastic member 500, and further improves the stability of the rotation and cleaning force of the brush head member 420.

[0062] During installation, the two ends of the elastic component 500 are respectively positioned within the first installation space 211 and the second installation space 411 for reliable and convenient installation. Specifically, the elastic component 500 is a spring, and the first installation space 211 and the second installation space 411 are slots that respectively accommodate the two ends of the spring. In other embodiments, the first installation space 211 and the second installation space 411 may also be formed by the walls of several or more structural components, or a connecting member may be provided on the basis of the first installation space 211 and the second installation space 411 to achieve the effect of installing the first end of the elastic component 500.

[0063] It is understandable that by cooperating with the second mounting space 411 and the first mounting space 211, the elastic component 500 can further reduce vibration and instability during power transmission.

[0064] Furthermore, in other embodiments, when the first end of the elastic component 500 is indirectly connected to the inner shaft component 200 through a transmission mechanism or connecting structure, by defining the structure of the transmission mechanism or connecting structure, the transmission mechanism or connecting structure is equipped with the ability to convert the rotational motion of the inner shaft component 200 into a swinging motion of the elastic component 500, thereby achieving the effect of power transmission. Specifically, the transmission mechanism can be a swing arm type transmission mechanism, a crank type or a connecting rod type transmission mechanism, etc., to drive the elastic component 500 to swing through the inner shaft component 200.

[0065] When the first end of the elastic component 500 is directly disposed on the circumference of the inner shaft component 200, the connecting structure can be a threaded fastener, a limiting component, or a clamping component, etc., to position and fix the elastic component 500 on the circumference of the inner shaft component 200. In this case, the elastic component 500 swings directly with the rotation of the inner shaft component 200. When the first end of the elastic component 500 is disposed on the end of the inner shaft component 200, the connecting structure not only serves as a connector to fix the elastic component, but also as a swing arm that swings with the rotation of the inner shaft component 200, and drives the elastic component 500 to swing synchronously, thereby achieving the effect of power transmission.

[0066] In other embodiments, the first end of the elastic component 500 can be adaptively adjusted to be located at a position other than the center point of the end of the inner shaft component 200, which can also achieve the effect of the inner shaft component 200 rotating to drive the second end of the elastic component 500 to make circular motion and realize power transmission.

[0067] In other embodiments, based on the fact that the oscillation of the elastic component 500 can drive the mounting component 400 to rotate, the position of the second end of the elastic component 500 relative to the mounting component 400 can be adaptively adjusted, thereby achieving the effect of power transmission. Furthermore, when the second end of the elastic component 500 is indirectly connected to the mounting component 400 through a transmission mechanism, by defining the structure of the transmission mechanism, the transmission mechanism has the ability to convert the oscillating motion of the elastic component 400 into the rotational motion of the mounting component 400, thereby achieving the effect of power transmission. Specifically, the transmission mechanism can be a crank-rocker type mechanism, an oscillating guide rod type mechanism, or a combination mechanism of a gear train and an oscillating follower, etc.

[0068] In some embodiments, the second mounting portion 410 and the first mounting portion 210 may also employ other common connection methods to fix the two ends of the spring, such as using threaded fasteners, limiting members, or clamping members for positioning and fixing. Conventional connection methods that can achieve similar effects and equivalent replacements should be considered as disclosed and fall within the protection scope of this application.

[0069] In some embodiments of this application, the elastic component 500 is a spring, a flexible structural member, or a flexible sheet.

[0070] In some embodiments, the elastic component 500 is a spring. It is understood that the spring can not only be easily installed on the mounting component 400 and the inner shaft component 200, but also has good deformation effect and high degree of freedom, thus meeting the requirements of stable power transmission and reducing noise generated during cleaning.

[0071] In some specific embodiments of this application, the mounting component 400 is inserted into the spring through the slot, and the other end of the spring is inserted into the slot of the inner shaft component 200. The inner shaft component 200 is driven to swing left and right by the power of the handle motor shaft, which in turn drives the spring to swing and drive the toothbrush head to rotate left and right, so as to realize the rotation of the bristles. Moreover, this new structure has a better noise effect when it is in operation.

[0072] In other embodiments, structural components that can perform similar functions and achieve equivalent replacement effects, such as flexible structural components, flexible springs, elastic connectors, flexible strips, and other conventional means, should all be considered as disclosed and fall within the protection scope of this application.

[0073] In one specific embodiment, refer to Figure 2 , Figure 3 and Figure 5 The rotation axis of the mounting component 400 and the rotation axis of the inner shaft component 200 are perpendicular to each other;

[0074] In the initial state when the electric toothbrush is not started, the second mounting part 410 and the first mounting part 210 are arranged opposite each other on the same straight line, and the compact structural design makes the power transmission effect more stable.

[0075] It should be understood that adjusting the way the inner shaft component 200 is positioned on the housing component 100 is an effective means to ensure a more stable power transmission to the drive component 300.

[0076] Based on this, in some embodiments of this application, such as Figure 5One end of the inner shaft component 200 is connected to the drive component 300, and the rotation center point of the opposite end of the inner shaft component 200 is concentric with the rotation center point of the output shaft of the drive component 300. It can be understood that the rotation top fulcrum of the inner shaft component 200 is concentric with the handle motor shaft, resulting in smoother operation and less noise when the inner shaft component 200 is in operation.

[0077] The spring-driven design allows the motor's power to be converted into the brush head's rotational power more stably. During power transmission, this not only ensures smoother operation and lower noise for the inner shaft component 200, but also significantly reduces vibration and instability during power transmission due to the spring's buffering and regulating effect. This further ensures that the brush head component 420 rotates at a relatively stable speed and force, maintaining a stable cleaning effect and lower noise.

[0078] In some embodiments of this application, the mounting component 400 is disposed on the housing component 100 by means of a snap-fit ​​connection. It is understood that the mounting component 400 is assembled by snap-fit ​​pressing, which is convenient and quick, avoids complicated assembly steps and saves on fixture costs, reduces labor and fixture costs, and improves production efficiency.

[0079] Specifically, refer to Figure 6 The mounting component 400 is detachably connected to the housing component 100 via the snap-fit ​​structure 700. After the mounting component 400 is installed onto the housing component 100 via the snap-fit ​​structure 700 and is successfully in place, the mounting component 400 can rotate smoothly relative to the housing component 100.

[0080] It should be understood that the key to achieving lower noise and smoother rotation of the brush head component 420 lies in the method and structural design of limiting and guiding the rotation of the mounting component 400.

[0081] In some embodiments of this application, a guide structure 600 is provided between the housing component 100 and the mounting component 400 to guide the rotation of the mounting component 400. This track-type design results in low operating noise for the electric toothbrush, providing a better consumer experience.

[0082] In one specific embodiment, refer to Figure 6 The guide structure 600 includes a sliding portion 610 and a track portion 620. The track portion 620 is formed within the housing component 100, and the sliding portion 610 is formed on the mounting component 400. The sliding portion 610 is slidably disposed on the track portion 620. It is understood that the sliding portion 610 of the mounting component 400 and the track portion 620 of the housing component 100 are mutually engaged, and the track-type operation design makes the brush head component 420 operate more smoothly during operation.

[0083] In some embodiments of this application, a brush head component 420 is provided on the mounting component 400;

[0084] In some embodiments, the brush head component 420 is detachably connected to the mounting component 400, thereby facilitating replacement and continued use.

[0085] In some embodiments, the brush head component 420 and the mounting component 400 are integrated into one piece, which facilitates mass production, reduces assembly steps, and improves production efficiency.

[0086] The electric toothbrush of this application embodiment is described in detail below with a specific example. It should be noted that the following embodiment is merely an exemplary description and should not be construed as limiting the embodiments of this application.

[0087] See Figures 1 to 6 As shown, the electric toothbrush of this embodiment consists of a toothbrush head, a spring, an inner shaft, a toothbrush head body, and a tail cap. The toothbrush head is inserted into the spring via a slot, and the other end of the spring is inserted into the inner shaft. The handle motor shaft drives the inner shaft to oscillate left and right, causing the spring to swing and thus driving the toothbrush head to rotate left and right, achieving the rotation of the bristles. This new structure also has better noise reduction during operation. Furthermore, the top pivot point of the inner shaft rotation is concentric with the center point of the handle motor shaft, resulting in smoother operation and lower noise. The toothbrush head is assembled using a snap-fit ​​method, which is convenient and quick, avoiding complicated assembly steps and saving on fixture costs, reducing labor and fixture costs, and improving production efficiency. At the same time, the product adopts a track-type design, resulting in low operating noise and providing a better consumer experience.

[0088] It's important to note that the spring-oscillating design effectively converts the motor's power into the brush head's rotational power. During power transmission, the spring acts as a buffer and regulator, reducing vibration and instability, ensuring the brush head rotates at a relatively stable speed and force, maintaining consistent cleaning performance. Compared to some complex transmission systems, the spring-oscillating design simplifies the brush head's rotation structure. While achieving brush head rotation, it effectively reduces energy loss and improves energy efficiency, allowing the toothbrush to work continuously for a longer period with the same amount of electricity, combining energy saving and high efficiency. Due to the spring-oscillating buffering effect, the external force on the brush head during rotation is relatively even, preventing the bristles from bending or breaking due to excessive force, extending the bristle lifespan, and allowing the brush head to maintain good cleaning performance for a longer period.
