[0037] In this document, terms such as “equal” and “same” are not strict mathematical and / or geometric limitations, but also include errors that are understandable to those skilled in the art and permissible in manufacturing or use.

[0038] This disclosure provides a handle for an oral hygiene appliance and an oral hygiene appliance, wherein the oral hygiene appliance includes the handle. The specific structure and working principle of the oral hygiene appliance provided by this disclosure will be described in detail below with reference to the accompanying drawings, and the specific structure and working principle of the handle of the oral hygiene appliance provided by this application will also be introduced.

[0039] This disclosure provides an oral hygiene appliance, which can be an electric toothbrush, a rinsing and brushing device, or other equipment used for oral hygiene. (See reference...) Figures 1 to 3 The oral hygiene appliance includes an oral hygiene appliance handle 100 and a brush head 200. The oral hygiene appliance handle 100 includes a housing 1, a drive assembly 2, and a mounting bracket 3. The housing 1 is configured for gripping, allowing the user to hold the housing 1 and operate the oral hygiene appliance for oral cleaning. Figure 2 As shown, the housing 1 has an inner cavity 10, which is used to accommodate various components in the handle 100 of the oral cleaning instrument.

[0040] like Figure 2 As shown, the drive assembly 2 is disposed in the inner cavity 10, specifically, as... Figure 3 As shown, the drive assembly 2 includes a drive motor 21, which includes an output shaft 211 and is configured to output power through the output shaft 211. The output shaft 211 can be used to connect to a brush head 200 of an oral hygiene appliance. Specifically, the brush head 200 is disposed at the end of the handle 100 of the oral hygiene appliance and is configured to be connected to the output shaft 211. The brush head 200 may include bristles 201, which are formed by multiple bristle clusters and are used to contact the teeth to achieve the brushing function. The output shaft 211 of the drive motor 21 can drive the brush head 200 to oscillate, thereby improving the cleaning effect.

[0041] In one specific embodiment of this disclosure, the drive motor 21 can be a servo motor, which can control the swing speed of the output shaft 211 with very accurate position control. This allows the output shaft 211 to reciprocate forward and reverse by a predetermined angle around its extended axis, thereby outputting swing power to drive the brush head 200 to vibrate. Users can easily clean toothbrush dirt without swinging their wrists while brushing their teeth, ensuring a cleaning effect.

[0042] The mounting bracket 3 is disposed in the inner cavity 10, and the drive assembly 2 and various components in the inner cavity 10 can be fixed by the mounting bracket 3. In one embodiment of this disclosure, reference is made to... Figure 4 The mounting bracket 3 has a first mounting space 301 for accommodating the drive assembly 2. (See reference) Figures 2 to 4 The mounting bracket 3 may also be provided with a second mounting space 302 for accommodating the battery 5. The first mounting space 301 may be connected to the second mounting space 302, so that the battery 5 in the second mounting space 302 can supply power to the drive motor 21 in the first mounting space 301.

[0043] like Figure 4 As shown, a through hole 32 is provided on the first end face of the mounting bracket 3, and the output shaft 211 is configured to extend through the through hole 32 to the outside of the first mounting space 301. The drive motor 21 is embedded in the first mounting space 301, and the end face of the drive motor 211 with the output shaft 211 abuts against the first end face of the mounting bracket 3, thereby allowing the output shaft 211 to pass through the through hole 32 and extend to the outside of the first mounting space 301, thus connecting with the brush head 200. In this way, the drive assembly 2 can be securely installed in the first mounting space 301, and the vibration of the drive motor 21 during operation will not cause relative movement of the drive assembly 2 relative to the mounting bracket 3.

[0044] refer to Figure 1 The housing 1 has a screen lens 11, and the screen lens 11 has a display area 12. (Reference) Figure 2 , Figure 3 , Figure 6 and Figure 7 The oral hygiene appliance handle also includes a display component 6, which is disposed between the mounting bracket 3 and the screen lens 11. Specifically, the display component 6 includes a display screen body 61, which has a first side 611 near the screen lens 11 and a second side 612 near the mounting bracket 3. The first side 611 includes a display area corresponding to the display area 12 and a mounting area that at least partially surrounds the display area. The display area is configured to display visual information that can be transmitted to the display area 12; the mounting area is configured to connect the display screen body 61 to the inside of the screen lens 11.

[0045] Specifically, the screen lens 11, as an external visible component of the housing 1, has at least a portion of its display area 12 constructed as transparent or semi-transparent, ensuring that visual information in the display area of ​​the screen body 61 can be transmitted. This visual information can include various information such as the current vibration mode of the oral hygiene appliance, the status of the switch, the current gear, and the remaining battery power. Users can intuitively see this visual information, thereby assisting them in better using the oral hygiene appliance.

[0046] In one embodiment of this disclosure, the screen lens 11 is configured to be located on the side of the housing 1 facing the direction of extension of the bristles 201. This allows the user to clearly observe the displayed content without adjusting their grip when cleaning their mouth, improving ease of operation.

[0047] The display component 6 is sandwiched between the mounting bracket 3 and the screen lens 11. The first side 611 of the display body 61 directly faces the screen lens 11. It can be understood that the display area is the core display area of ​​the display body 61, and its size should be adapted to the display area 12 of the screen lens 11 to achieve a beautiful and clear display effect. The mounting area is the non-display area surrounding the display area. In the assembled state, the mounting area is covered by the opaque structure on the housing 1, thus hiding the less aesthetically pleasing mounting area. Specifically, the mounting area can be connected to the inner side of the screen lens 11 by adhesive, bonding, or other methods, thereby fixing the display body 61.

[0048] The display body 61 of this disclosure is directly connected to the screen lens 11 via a mounting area. This allows the display area of ​​the display body 61 to be as close as possible to the screen lens 11, shortening the distance between the display area and the screen lens 11. This reduces light refraction and reflection during propagation, avoiding problems such as blurring, distortion, and glare in the displayed content, significantly improving the visual effect and ensuring that users can clearly observe the displayed information. Furthermore, by providing a mounting area at least partially surrounding the display area on the first side 611 of the display body 61, and using this mounting area to directly connect the display body 61 to the inner side of the screen lens 11, this disclosure simplifies the installation process of the display component 6 compared to the complex structure of the prior art that uses multiple connectors to fix the display. This improves production efficiency and reduces assembly difficulty and cost during production.

[0049] In one embodiment of this disclosure, the second side 612 is configured to be connected to the mounting bracket 3. The second side 612 of the display body 61 and the mounting bracket 3 can be connected using a suitable method, such as by bonding, snap-fitting, or adhesive, so that both sides of the display body 61 are simultaneously fixed by both the screen lens 11 and the mounting bracket 3. This ensures the stability of the display body 61 within the inner cavity 10 and prevents displacement of the display body 61 due to vibrations during use of the oral hygiene device. This improves the installation stability of the display body 61, ensures the accuracy of the display position, and the bidirectional fixing structure can disperse external forces on the display body 61, reducing the risk of damage and extending the service life of the display assembly 6.

[0050] In one embodiment of this disclosure, a first buffer pad 621 is provided between the mounting area and the screen lens 11, and a second buffer pad 622 is provided between the second side 612 and the mounting bracket 3. Specifically, the first buffer pad 621 and the second buffer pad 622 can be made of elastic flexible materials, such as foam or sponge pads. The first buffer pad 621 covers the connection surface between the mounting area of ​​the display body 61 and the inner side of the screen lens 11, filling the tiny gap between them. The first buffer pad 621 can buffer the collision force between the display body 61 and the screen lens 11, avoiding component wear caused by hard contact. The second buffer pad 622 is provided on the connection surface between the second side 612 of the display body 61 and the mounting bracket 3, adapting to the contact contour of the two. The second buffer pad 622 can absorb the vibration generated during the use of oral hygiene appliances, reducing the impact of vibration on the display body 61, preventing screen flicker, and also compensating for installation errors, improving assembly adaptability.

[0051] In one embodiment of this disclosure, such as Figure 7 As shown, a groove 111 is provided on the screen lens 11 at the position corresponding to the display area 12. The groove 111 is constructed to create a spatial gap between the display body 61 and the screen lens 11. The groove 111 is located inside the screen lens 11, and its area is adapted to the display area of ​​the display body 61. The structural design of the groove 111 ensures that a reserved spatial gap is formed between the display area and the inner wall of the groove 111, preventing direct contact between the display area and the screen lens 11. This prevents the screen lens 11 from squeezing the display body 61, avoiding damage to the display area or display abnormalities. At the same time, the spatial gap can also serve as a buffer area for light propagation, reducing the impact of the screen lens 11 on the display effect.

[0052] In one embodiment of this disclosure, reference is made to Figure 5 and Figure 7 The mounting bracket 3 has a support protrusion 31 on the side near the screen lens 11. Under the action of the driving component 2, the mounting bracket 3 is configured to move the support protrusion 31 to abut against the inner wall of the housing 1, thereby restricting the freedom of movement of the display component 6. Specifically, when the driving component 2 is working, it causes the mounting bracket 3 to vibrate slightly. As the mounting bracket 3 moves toward the screen lens 11, the support protrusion 31 abuts against the inner wall of the housing 1, thereby limiting the movement of the mounting bracket 3 and restricting the movement of the display component 6 with the mounting bracket 3. This ensures the relative position stability of the display component 6 and the screen lens 11, avoids collisions between the display component 6 and the screen lens 11, and also avoids affecting the display effect.

[0053] In one embodiment of this disclosure, a support protrusion 31 is disposed on the mounting bracket 3 near the first end face. As mentioned above, the first end face is the end face with a through hole 32 for the output shaft 211 to pass through. The support protrusion 31 is disposed near the first end face, thereby being close to the power output end of the output shaft 211. When the output shaft 211 transmits power, the support protrusion 31 can specifically limit the swaying of the mounting bracket 3 near the power output end, reduce the impact of vibration during power transmission on the display component 6, and improve the overall structural stability.

[0054] In one embodiment of this disclosure, reference is made to Figure 1 and Figure 7 The oral hygiene appliance handle 100 also includes a button assembly 8, which is disposed on the screen lens 11. The button assembly 8 includes a flexible member 82 and a button body 81 disposed outside the flexible member 82. The button body 81 is configured to deform the flexible member 82 under external force. Specifically, the flexible member 82 can be made of soft rubber and is disposed inside the screen lens 11 corresponding to the position of the button body 81. The button body 81 is a rigid structure and is disposed outside the flexible member 82, maintaining a flat surface or conforming to the curvature of the screen lens 11. The button body 81 is exposed outside the housing 1. When an external force presses the button body 81, the flexible member 82 deforms and triggers an internal switch, thereby realizing the control function. After the external force is removed, the flexible member 82 can automatically reset the button body 81.

[0055] This disclosure integrates the button assembly 8 onto the screen lens 11, thus forming a one-piece structure. This eliminates the need for separate mounting holes for the button assembly 8 on the housing 1, avoiding sealing issues that might result from separate holes on the housing 1. Furthermore, the one-piece structure reduces assembly steps, lowers production complexity, and avoids the cumbersome process of separately waterproofing and sealing the button assembly 8.

[0056] In one embodiment of this disclosure, the housing 1 has an opening, and the screen lens 11 is configured to be adhesively bonded into the opening, so that a waterproof adhesive layer is formed between the outer periphery of the screen lens 11 and the inner wall of the opening. The size of the opening on the housing 1 is adapted to the screen lens 11. The screen lens 11 is fixed in the opening after the waterproof adhesive is applied to its outermost ring. The adhesive fills the annular gap between the outermost ring of the screen lens 11 and the inner wall of the opening, forming a continuous and complete waterproof adhesive layer that covers the entire gap without any breaks. Furthermore, since the button assembly 8 is integrated with the screen lens 11, there is no need to set an additional sealing structure at the corresponding position of the button assembly 8. The overall waterproofing, including the button area, can be achieved simply by the waterproof adhesive layer around the outermost ring of the screen lens 11, thereby simplifying the assembly process and reducing the manufacturing difficulty. In one embodiment of this disclosure, reference is made to Figure 2 and Figure 3The oral hygiene appliance handle 100 also includes a control main board 4 disposed within its inner cavity. The control main board 4 can be fixed to the mounting bracket 3 and connected to various components within the oral hygiene appliance handle 100, thereby controlling the coordinated operation of these components. (Reference) Figure 6 The display component 6 includes a display circuit board 63, which is configured to be disposed on the second side 612 and to extend to communicate with the control motherboard 4. Specifically, the display circuit board 63 can be soldered onto the control motherboard 4, and the control motherboard 4 can transmit control signals to the display body 61 through the display circuit board 63.

[0057] This disclosure places the display circuit board 63 on the second side 612 of the display body 61, thereby preventing the display circuit board 63 from obstructing the display area and ensuring that the user can fully and clearly observe the visual information transmitted from the display area to the display area of ​​the screen lens 11. Furthermore, since the second side 612 is close to the mounting bracket 3, the distance between the display circuit board 63 on the second side 612 and the control motherboard 4 fixed on the mounting bracket 3 is relatively short. This allows the extended portion of the display circuit board 63 to connect to the control motherboard 4 without being excessively long, reducing the difficulty of wiring layout and simplifying the wiring connection steps during assembly.

[0058] In one embodiment of this disclosure, reference is made to Figure 2 The oral hygiene appliance handle 100 also includes a light-emitting component 7. In various scenarios such as low battery, charging, mode switching, or excessive brushing pressure, the light-emitting component 7 provides timely visual feedback to the user. In existing technologies, one or more LED beads can be used as the light source for the light-emitting component 7. However, using a single LED bead makes it difficult to achieve uniform light emission, and using multiple LED beads also results in uneven light emission due to differences in brightness and color among the individual beads. Users will directly see the uneven light spots from the LED beads, leading to poor aesthetics.

[0059] To solve the above problems, refer to Figure 3 and Figure 8The light-emitting component 7 disclosed herein includes a light source 71 and a light guide 72. The light source 71 is disposed on a mounting bracket 3, and the light guide 72 is disposed on a housing 1. At least a portion of the outer peripheral surface of the light guide 72 is exposed outside the housing 1 to form a light-emitting surface 721. The light guide 72 is configured to guide light from the light source 71 to at least the light-emitting surface 721, wherein, in the radial direction of the housing 1, the orthographic projection of the light-emitting surface 721 is configured to be offset from the orthographic projection of the light source 71. Specifically, the light guide 72 is made of a light-transmitting material, and the internal structure of the light guide 72 can guide the light from the light source 71 to the light-emitting surface 721. The light-emitting surface 721 is offset from the orthographic projection of the light source 71, thereby preventing the strong light from the light source 71 from directly illuminating the light-emitting surface 721, causing local overbrightness or glare, and avoiding the user from observing uneven light spots. Under the action of the light guide 72, the light can be evenly distributed on the light-emitting surface 721, thereby improving visual comfort and enhancing the aesthetics of the oral hygiene appliance.

[0060] In one embodiment of this disclosure, the light source 71 is disposed on the mounting bracket 3 near the light guide 72, thereby shortening the distance between the light source 71 and the light guide 72. This allows the light emitted by the light source 71 to enter the light guide 72 more directly, reducing light loss during propagation. This ensures that the light-emitting surface 721 has sufficient brightness, while eliminating the need for additional light-focusing components and simplifying the structure of the light-emitting assembly 7.

[0061] In one embodiment of this disclosure, the light guide 72 includes a guide portion 722 extending into the inner cavity 10. The guide portion 722 is configured to extend at least to couple with the light source 71. The light guide 72 is configured to guide light to the light-emitting surface 721 through the guide portion 722. Specifically, the guide portion 722 is an extension structure extending into the inner cavity 10, and its end face can be close to or connected to the light source 71 to form light coupling. The guide portion 722 transmits the light from the light source 71 to the light-emitting surface 721 through reflection, refraction, or other means, ensuring that the light propagates along a predetermined path. In one embodiment of this disclosure, a predetermined gap exists between the mounting bracket 3 and the inner wall of the housing 1, and a portion of the guide portion 722 is configured to be located within the predetermined gap. This disclosure utilizes the predetermined gap between the mounting bracket 3 and the inner wall of the housing 1 to accommodate the guide portion 722, thereby eliminating the need for additional mounting space on the housing 1 or the mounting bracket 3, saving space in the inner cavity 10, and optimizing the internal structural layout of the oral cleaning appliance handle 100.

[0062] In one embodiment of this disclosure, the guide portion 722 includes a mating area for coupling with a light source 71. The light guide 72 is configured to extend along a first direction, and the mating area and the light-emitting surface 721 are configured to be spaced apart along the first direction. Specifically, the first direction is the extending direction of the oral hygiene appliance handle 100, and the housing 1 and the mounting bracket 3 are configured to extend along the first direction. The mating area and the light-emitting surface 721 are spaced apart along the first direction, thereby enabling light to be transmitted along the first direction. The housing 1, the mounting bracket 3, and the light guide 72 extend in the same direction, thereby achieving a regular layout of the various structures in the cavity 10, maximizing the use of the space in the cavity 10, making the overall size of the oral hygiene appliance handle 100 smaller and easier for the user to hold. At the same time, the uniform extending direction can reduce interference between components and improve assembly efficiency. In one embodiment of this disclosure, the light source 71 is a point light source. For example, the light source 71 can be an LED lamp bead. The point light source is small in size and fits the compact layout in the inner cavity 10. In addition, the point light source can be precisely fixed on the mounting bracket 3, and the light emitted is concentrated, which facilitates coupling with the guide portion 722 of the light guide 72, ensuring sufficient brightness of the light-emitting surface 721. At the same time, the point light source has low energy consumption and long lifespan, thereby reducing the use cost and maintenance frequency of the oral cleaning instrument handle 100.

[0063] In one embodiment of this disclosure, such as Figure 9 As shown, the light source 71 includes a light source circuit board 711, which is configured to be disposed on the mounting bracket 3 near the light guide 72 and is configured to extend to communicate with the control motherboard 4. Specifically, the light source circuit board 711 can be soldered onto the control motherboard 4, and the control motherboard 4 can transmit control signals to the light source 71 through the light source circuit board 711, thereby performing intelligent control of the light source 71.

[0064] In one embodiment of this disclosure, reference is made to Figure 3 The oral hygiene appliance handle 100 also includes a sensing component 9, which is configured to sense the force applied to the output shaft 211. A control board 4 is configured to communicate with the sensing component 9 and is configured to determine the pressure value applied to the output shaft 211 based on the electrical signal output by the sensing component 9. When the pressure value exceeds a threshold, the control board 4 is configured to control the light source 71 to emit a light signal. The sensing component 9 can monitor the pressure on the output shaft 211 in real time. When the pressure value exceeds the threshold, it means that the user's brushing force is too strong. To remind the user to reduce the brushing force, the control board 4 can control the light source 71 to turn on. The light signal from the light source 71 is evenly transmitted to the light-emitting surface 721 via the light guide 72. The user can notice the light signal emitted from the light-emitting surface 721 and thus adjust the brushing force, which is beneficial for protecting dental health.
