[0002] With the improvement of living standards, people's awareness of oral care has gradually increased, and the oral care tools on the market have become more diverse. Taking an electric toothbrush as an example, the drive motor in the handle can drive the toothbrush head to swing or vibrate. When brushing teeth, the user holds the handle and presses the toothbrush head against the teeth to clean the teeth.

[0003] A light-emitting component can be provided on the electric toothbrush. In various scenarios such as when the battery power of the electric toothbrush is insufficient, the electric toothbrush is charging, the mode of the electric toothbrush is switched, or the user brushes teeth with too much force, the light-emitting component can provide timely visual feedback to the user. In the prior art, a single LED or multiple LEDs can be used as the light source. However, it is difficult to achieve uniform light emission when using a single LED; when using multiple LEDs, since there are certain differences in the brightness and color of each LED, it is also difficult to achieve uniform light emission.

[0045] Various exemplary embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings. It should be noted that: unless otherwise specifically stated, the relative arrangements of components and steps, numerical expressions and values set forth in these embodiments do not limit the scope of the present disclosure.

[0046] The following description of at least one exemplary embodiment is merely illustrative in nature and in no way serves as a limitation to the present disclosure or its application or use.

[0047] Techniques, methods, and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be regarded as part of the specification.

[0048] It should be noted that: like reference numerals and letters denote like items in the following drawings, and thus, once an item is defined in one drawing, further discussion thereof in subsequent drawings is not necessary.

[0049] In this document, "upper", "lower", "front", "rear", "left", "right", etc. are only used to represent the relative positional relationships between relevant parts, rather than defining the absolute positions of these relevant parts.

[0050] In this document, "first", "second", etc. are only used for distinguishing from each other, rather than indicating importance, order, and the prerequisite for mutual existence, etc.

[0051] In this document, "equal", "same", etc. are not strict mathematical and / or geometric limitations, and also include the errors that can be understood by those skilled in the art and are allowed in manufacturing or using, etc.

[0052] Reference Figure 1, Figure 2 , Figures 4 to 6 , the present disclosure provides a handle 100 for an oral cleaning appliance, which can be used for oral cleaning appliances such as electric toothbrushes, flushing integrated machines, etc. The handle 100 of the oral cleaning appliance includes: a housing 1 and a light-emitting component. Among them, the housing 1 is configured to be suitable for holding, and a user can hold the housing 1 by hand to operate the oral cleaning appliance. An inner cavity can be provided in the housing 1, and the inner cavity can be used to accommodate various components of the handle 100 of the oral cleaning appliance.

[0053] The light-emitting component is arranged on the housing 1. In various application scenarios, the light-emitting component can provide visual feedback to the user in a timely manner. Specifically, the light-emitting component includes a light source 21, a light guide 22, and a light-transmitting member 23. The light source 21 can emit a light signal, and the light signal is conducted to the light-transmitting member 23 through the light guide 22. At least a part of the outer peripheral surface of the light-transmitting member 23 is exposed outside the housing 1, so that the user can observe the light signal.

[0054] In a specific embodiment of the present disclosure, referring to Figure 1 and Figure 3 , the light-transmitting member 23 has a light-transmitting area 231. As shown in Figure 1 , the light-transmitting area 231 can be at least partially exposed at a position outside the housing 1, specifically at a position between the handle 100 of the oral cleaning appliance and the brush head 200. The light signal emitted by the light source 21 can be conducted to the light-transmitting area 231, which is convenient for the user to observe. Setting the light-transmitting area 231 at the position between the handle 100 of the oral cleaning appliance and the brush head 200 improves the aesthetics of the oral cleaning appliance. The circumferentially arranged light-transmitting area 231 is convenient for the user to observe, and the user can observe the brightness and darkness state of the light-transmitting area 231 from any angle.

[0055] Referring to Figures 4 to 6 , the light guide 22 includes: a first guiding portion 221 coupled to the light source 21, an output portion 223 for cooperating with the light-transmitting member 23, and a second guiding portion 222 provided between the first guiding portion 221 and the output portion 223. The materials of the first guiding portion 221, the second guiding portion 222, and the output portion 223 are uniform, and the three structures can be integrally formed, thus jointly constituting the light guide 22. The light conduction rate at different positions in the light guide 22 is the same.

[0056] In one embodiment of the present disclosure, the light source 21 is a single point light source. For example, a single LED lamp can be used, and the LED lamp can be a two-color or three-color LED, thereby enriching the emission color. Compared with the solution of using multiple LEDs as the light source 21, a single LED can ensure that the emitted color and brightness are uniform. It can be understood that there are certain differences in the brightness and color of multiple LEDs, so it is also difficult to achieve uniform light emission; while using a single LED does not face problems such as color difference and brightness difference, as long as the light can be uniformly conducted to the light-transmitting member 23, uniform light emission can be achieved.

[0057] In one embodiment of the present disclosure, referring to Figure 4 and Figure 5 , a notch 2211 is provided at one end of the first guiding portion 221 adjacent to the light source 21, and the notch 2211 is configured to be coupled to the light source 21. The notch 2211 is coupled to the light source 21 in a flared shape, thereby playing a guiding role for the light. The notch 2211 can receive the light emitted by the light source 21 to the greatest extent, and the light is incident on the first guiding portion 221 of the light guiding member 22 therefrom. In order to ensure the effect of the notch 2211 receiving light, in a specific embodiment of the present disclosure, the emission angle of the light source 21 is configured to be greater than 45 degrees, so that the notch 2211 is on the light emission path of the light source 21, ensuring that the light emitted by the light source 21 can basically be received by the notch 2211, and improving the light reception amount of the light guiding member 22.

[0058] In the prior art, the light emitted by a single point light source is usually difficult to be uniformly conducted to the annular light-transmitting area 231. It can be understood that the position closer to the light source 21 is usually brighter, and the position farther from the light source 21 is usually darker. The present disclosure can homogenize the light by setting the structure of the light guiding member 22. Specifically, the light guiding member 22 is configured to guide the light to at least one side of the light-transmitting member 23 close to the light source 21 through the first guiding portion 221, and is configured to guide the light to at least one side of the light-transmitting member 23 far from the light source 21 through the first guiding portion 221 and the second guiding portion 222. After the light is incident on the first guiding portion 221 from the notch 2211, it can be conducted along two different optical paths, denoted as the first optical path and the second optical path: the light of the first optical path is only conducted in the first guiding portion 221, and it can directly reach the side of the output portion 223 close to the light source 21, and then be conducted to the side of the light-transmitting member 23 close to the light source 21; the light of the second optical path can be conducted through the first guiding portion 221 to the second guiding portion 222 located between the first guiding portion 221 and the output portion 223, and reach the side of the output portion 223 far from the light source 21 through the second guiding portion 222, and then be conducted to the side of the light-transmitting member 23 far from the light source 21. The optical paths of the first optical path and the second optical path are basically the same, so that the single point light source emitted by the light source 21 can be uniformly conducted to the entire light-transmitting member 23.

[0059] In the present disclosure, by providing a light guide member 22 having a first guiding portion 221 and a second guiding portion 222, the light emitted by the light source 21 is evenly distributed to the light transmissive member 23. Specifically, the first guiding portion 221 can directly guide the light to the side close to the light source 21; the light can also enter the second guiding portion 222 after passing through a part of the first guiding portion 221 and is guided by the second guiding portion 222 to the side away from the light source 21. The lengths of the above two optical paths are basically the same, so that the light guide member 22 can evenly distribute the light to the entire light transmissive member 23, and the brightness at each part of the light transmissive member 23 is basically the same. Even the side far from the light source 21 is bright enough. The light-emitting component on the handle 100 of the oral cleaning appliance realizes uniform light emission, thereby providing good visual feedback for the user.

[0060] Since the first guiding portion 221 is located on the side close to the light source 21, it can be seen that the straight-line distance from the notch 2211 to the position on the side of the output portion 223 close to the light source 21 is the shortest path for the light to conduct in the light guide member 22. It can be understood that if this is used as the first optical path, it is inevitable that a second optical path with a light path length basically the same as that of the first optical path cannot be designed. Therefore, it is necessary to truncate the straight-line conduction path of the light in the first guiding portion 221 to extend the first optical path.

[0061] In an embodiment of the present disclosure, as Figure 5 shown, the first guiding portion 221 is provided with a hollowed-out portion 2212, and the hollowed-out portion 2212 is configured to reflect the light to both sides of the first guiding portion 221 to extend the optical path of the light in the first guiding portion 221. Specifically, the hollowed-out portion 2212 is configured as a semi-circle, the arc vertex of the semi-circle is configured to be located adjacent to the notch 2211, and the straight side of the semi-circle is configured to be located on the side adjacent to the light transmissive member 23. Referring to Figure 5 the optical path arrows in, after the light enters the first guiding portion 221 from the notch 2211, it will be scattered to both sides of the hollowed-out portion 2212 under the reflection of the semi-circular arc on the side of the hollowed-out portion 2212 adjacent to the notch 2211, so as to bypass the hollowed-out portion 2212. After being scattered, the light propagating along the first optical path can converge to the side of the output portion 223 close to the light source 21 after bypassing the hollowed-out portion 2212. It can be seen that the hollowed-out portion 2212 truncates the straight-line conduction path of the light in the first guiding portion 221 and realizes the extension of the first optical path.

[0062] In an embodiment of the present disclosure, referring to Figure 5 and Figure 6, there are two second light guiding parts 222, and the two second light guiding parts 222 are respectively arranged on both sides of the first light guiding part 221. The first light guiding part 221 is configured to guide light to the two second light guiding parts 222, and the second light guiding part 222 is configured to shorten the optical path of the light reaching the side of the light transmissive member 23 away from the light source 21. Refer to Figure 5 the viewing direction, the side where the first light guiding part 221 is located is regarded as the front side, the second light guiding part 222 is arranged on the rear side of the first light guiding part 222, and the upper end of the second light guiding part 222 is connected to the side of the output part 223 away from the light source 21. Light can enter the second light guiding part 222 through the intersection position of the first light guiding part 221 and the second light guiding part 222, and reach the side of the output part 223 away from the light source 21 under the guiding action of the second light guiding part 222. The second light guiding part 222 effectively shortens the optical path of the second optical path and makes the optical paths of the second optical path and the first optical path basically the same. In this way, the light guiding member 22 provided in the present disclosure can homogenize the light, and the brightness at any position on the output part 223 can be kept basically the same.

[0063] In an embodiment of the present disclosure, as Figure 5 shown, the side of the output part 223 of the light guiding member 22 away from the light source 21 is configured as a light emitting surface 2231, and a light incident area is provided on the light transmissive member 23. The light incident area is configured to be adapted to the light emitting surface 2231 and is used to receive the light from the light emitting surface 2231. Specifically, light guiding lines are provided on the light emitting surface 2231, and the light guiding lines can be selected from VDI24 - VDI30 lines. By providing the light guiding lines, the light emitting surface 2231 can uniformly diffuse the light in the output part 223 to the outside. The light incident area of the light transmissive member 23 and the light emitting surface 2231 of the light guiding member 22 are correspondingly arranged. Specifically, the light emitting surface 2231 in this embodiment is configured as an annular surface, then the light incident area of the light transmissive member 23 is also configured as an annular surface. The light diffused from the light emitting surface 2231 can be uniformly conducted to the light transmissive member 23 through the light incident area, so that the light transmissive area 231 arranged in a surrounding manner and exposed outside the housing 1 can emit light uniformly.

[0064] In an embodiment of the present disclosure, as Figure 3As shown, the light-emitting component further includes a mounting member 24 for mounting the light-transmitting member 23 to the housing 1. Specifically, the light-transmitting member 23 and the mounting member 24 are formed into a first assembly by two-color die-casting, and the first assembly is configured to be mounted to the housing 1. At least a part of the outer peripheral surface of the light-transmitting member 23 (i.e., the light-transmitting area 231) is exposed outside the housing 1 and is not blocked by the mounting member 24. The mounting member 24 is made of a solid-color material, while the light-transmitting member 23 is made of a translucent material. After the light-transmitting member 23 and the mounting member 24 are formed into one body by two-color die-casting, the mounting member 24 will block a part of the light-transmitting member 23, achieving the effect of partial light shielding; at the same time, there is an unblocked part of the light-transmitting member 23, and the unblocked part can be exposed outside the housing 1, thereby forming an annular light-transmitting area 231 that is convenient for users to observe.

[0065] In one embodiment of the present disclosure, referring to Figure 4 and Figure 7 , the handle 100 of the oral cleaning appliance further includes a driving assembly 3, and the driving assembly 3 includes a driving motor 31. The driving motor 31 has opposite ends extending along the axis, which are respectively denoted as the output end 311 and the opposite end 312. The output end 311 can be used to connect the brush head 200 of the oral cleaning appliance, so that the driving motor 31 can drive the brush head 200 to swing, so that the oral cleaner has a good cleaning effect. Referring to Figure 3 and Figure 5 , the light-transmitting member 23 is configured to be annular, and a through hole 224 is provided on the light guide member 22. The output end 311 of the driving motor 31 is configured to sequentially penetrate through the through hole 224 and the light-transmitting member 23 to extend outside the housing 1. A through hole 224 is provided on the light guide member 22 to facilitate the output end 311 to pass through, and at the same time, the through hole 224 also plays a role of central limiting.

[0066] In one embodiment of the present disclosure, referring to Figure 2 and Figure 7 , the handle of the oral cleaning appliance further includes a bracket 7 fixedly arranged inside the housing 1 and a fixing cover 8 arranged on the bracket 7. Among them, the bracket 7 is used to fix various components inside the handle 100 of the oral cleaning appliance, and at least a part of the fixing cover 8 and the bracket 7 enclose a first installation space 71 for accommodating the driving assembly 3. The fixing cover 8 can be fixed to the bracket 7 by a plurality of screws 81 and, together with the bracket 7, fixes the driving assembly 3 in the first installation space 71. A second installation space 72 for accommodating the battery 721 can also be provided on the bracket 7, and the first installation space 71 can be communicated with the second installation space 72, so that the battery 721 in the second installation space 72 can supply power to the driving motor 31 in the first installation space 71.

[0067] In one embodiment of the present disclosure, a display assembly 4 is provided on one side of the driving assembly 3 close to the fixing cover 8. Referring to Figure 2, a display area 10 is provided on the housing 1. The display area 10 can be a transparent member provided on the housing 1 or a hollowed-out area. The side of the display assembly 4 close to the display area 10 is configured to display visual information. Specifically, the visual information can include various information such as the current vibration mode of the oral cleaning appliance, the state of the switch, the current gear, the remaining power, etc. The user can intuitively see these visual information, thereby assisting the user to better use the oral cleaning appliance.

[0068] As Figure 7 shown, an opening 80 is provided on the fixed cover 8. The opening 80 is configured to be at least adapted to the display assembly 4. The display assembly 4 is configured to transmit the display visual information to the display area 10 through the opening 80. In order to prevent the fixed cover 8 from blocking the display assembly 4, an opening 80 needs to be provided on the fixed cover 8. The opening 80 can be a hollow on the fixed cover 8, and the area of the opening 80 should be larger than the area of the display content on the display assembly 4, so as to ensure that the user can obtain the visual information completely.

[0069] In an embodiment of the present disclosure, as Figure 4 shown, the light source 21 is configured to be provided on the side of the bracket 7 away from the display assembly 4. Specifically, the display assembly 4 is installed on the drive assembly 3, specifically located on the side of the bracket 7 close to the fixed cover 8; while the light source 21 is provided on the side of the bracket 7 away from the fixed cover 8. Specifically, a groove 73 is provided on the side of the bracket 7 away from the display assembly 4. The groove 73 extends along the axial direction. The light source circuit board 211 connected to the light source 21 is arranged in the groove 73, and the light source circuit board 211 can be pasted in the groove 73 with double-sided tape. There are the bracket 7 and the drive assembly 3 blocking between the light source 21 and the display assembly 4, so they will not interfere with each other at all. The present disclosure reasonably arranges the display assembly 4 and the light source 21 in the compact space inside the housing 1. The light emitted by the light source 21 will not irradiate the display assembly 4, and the two do not interfere with each other. Thus, the lighting function and the display visual information function can be reasonably integrated on the handle 100 of the oral cleaning appliance, improving the user experience.

[0070] As Figure 2 shown, a control main board 6 is further provided in the housing 1. The control main board 6 is communicatively connected to the light source circuit board 211. The light source circuit board 211 can be soldered to the control main board 6, so that the control main board 6 controls the turning on or off of the light source 21.

[0072] For new users who have just started using an electric toothbrush, since they are used to the brushing force of using an ordinary toothbrush, they may apply too much force when using the electric toothbrush, resulting in oral injuries, which is not conducive to the health of teeth and periodontium. The present disclosure solves the above problems by detecting the magnitude of the force on the output end 311 connected to the brush head 200.

[0073] In an embodiment of the present disclosure, reference Figure 7 and Figure 8 , the oral cleaning appliance handle 100 further includes a sensor assembly 5, and the sensor assembly 5 includes a sensor body 51 and a flexible circuit board 52 connected to the sensor body 51. The sensor body 51 is disposed on the output end 311, one end of the flexible circuit board 52 is connected to the sensor body 51, and the other end extends in the receiving groove 320. The sensor body 51 disposed on the output end 311 can detect the magnitude of the force on the output end 311, and the flexible circuit board 52 can transmit the information detected by the sensor body 51 in the form of an electrical signal, thereby realizing real-time monitoring of the magnitude of the force on the output end 311. The user can know whether the current brushing force is appropriate, so as to adjust the force in time, which is beneficial to the health of teeth and periodontium.

[0074] Such as Figure 8As shown, a stepped groove 3201 is provided in the receiving groove 320. The stepped groove 3201 can be provided on the bottom surface of the receiving groove 320. A part of the flexible circuit board 52 extending into the receiving groove 320 is configured to be located in the stepped groove 3201 to form an assembly gap with the display component 4. To ensure the normal function of the sensor component 5, the flexible circuit board 52 needs to be in a relaxed state and not be pressed or involved by other components, otherwise it is easy to cause inaccurate measurement of the sensor component 5. The display component 4 provided in the receiving groove 320 together with the flexible circuit board 52 is located above the flexible circuit board 52. Therefore, a stepped groove 3201 for receiving the flexible circuit board 52 needs to be opened on the bottom surface of the receiving groove 320. The flexible circuit board 52 can remain in a relaxed state in the stepped groove 3201 and will not be pressed by the display component 4.

[0075] The flexible circuit board 52 is communicatively connected to the control main board 6. Specifically, the flexible circuit board 52 can be soldered to the control main board 6. The control main board 6 is configured to determine the pressure value received at the output end 311 based on the electrical signal output by the sensor body 51. When the pressure value is greater than the threshold, the control main board 6 is configured to control the light source 21 to output an optical signal. It can be understood that when the pressure value is greater than the threshold, it means that the user's brushing force is too large. To remind the user to reduce the brushing force, the control main board 6 can control the light source 21 to turn on. The optical signal of the light source 21 is evenly conducted to the light-transmitting member 23 through the light guide member 22. The user can notice the optical signal emitted by the light-transmitting member 23, thereby adjusting the brushing force, which is beneficial to protecting dental health.

[0076] In an embodiment of the present disclosure, as Figure 8 shown, the flexible sleeve 32 includes a front sleeve 321 and a rear sleeve 322. The front sleeve 321 and the rear sleeve 322 can be made of the same flexible material. The front sleeve 321 and the rear sleeve 322 respectively partially wrap the output end 311 and the opposite end 312 of the drive motor 31. The receiving groove 320 is provided on the front sleeve 321. The display component 4 is completely located on the front sleeve 321 and will not be partially located on the front sleeve 321 and partially located on the rear sleeve 322. It can be understood that when the drive motor 31 is working, vibrations may occur, and the vibrations may cause relative movement between the front sleeve 321 and the rear sleeve 322. If the display component 4 straddles the front sleeve 321 and the rear sleeve 322, the display component 4 will be stressed as a result, which may cause damage to the display component 4. Therefore, the display component 4 needs to be entirely provided on the front sleeve 321. The display component 4 can move together with the front sleeve 321 without being subjected to a pulling force, thereby protecting the display component 4 and extending the life of the display component 4.

[0077] In an embodiment of the present disclosure, as Figure 7As shown, the driving component 3 includes a flexible waterproof member 33 sleeved on the output end 311. Specifically, the inner wall of the flexible waterproof member 33 is in interference fit with the outer wall of the output end 311. The outer wall of the flexible waterproof member 33 is configured to be at least partially pre-pressed against the inner wall of the housing 1. Further, as Figure 5 shown, a step groove 225 is provided at the inner wall position of the through hole 224 of the light guide member 22, and the bottom surface of the flexible waterproof member 33 is configured to be pre-pressed against the step groove 225. In the axial direction of the output end 311, both ends of the flexible waterproof member 33 are respectively pre-pressed against the step groove of the light guide member 22 and the inner wall surface of the housing 1, thereby achieving the function of sealing and waterproofing. When the oral cleaning appliance is an electric toothbrush, the brush head 200 mounted on the output end 311 will directly contact water, and the water may flow along the brush head 200 to the output end 311. To prevent the liquid from flowing to the driving motor 31 and causing a short circuit, the present disclosure provides a flexible waterproof member 33 sleeved on the output end 311. The flexible waterproof member 33 can isolate the water, thereby preventing the driving motor 31 from contacting the water and improving the safety of the oral cleaning appliance.
