Description

Technical Field

[0001] This application relates to the field of oral hygiene technology, and more particularly to an oral hygiene component and an oral hygiene device. Background Technology

[0002] Oral cleaning devices incorporate light-emitting components that continuously emit blue light during operation. When brushing teeth, this blue light acts on the functional components of oral cleaning agents (such as toothpaste and tooth gel) to activate related reactions and accelerate pigment decomposition, thereby promoting a whitening effect.

[0003] In related technologies, oral cleaning devices guide and emit light through the bristles of the cleaning section. However, due to limitations in the manufacturing process, the light loss in the bristles is severe, resulting in insufficient effective light energy and low light utilization rate for the oral cleaning agent, which affects the whitening effect.

[0029] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0030] During brushing, oral hygiene devices repeatedly clean the tooth surface, interdental spaces, and gum line through their cleaning section, achieving thorough cleaning of the teeth and oral cavity. When light-assisted technology is incorporated into oral hygiene devices, the light-emitting component is typically positioned corresponding to the cleaning section. For example, a blue light-emitting component is placed at the root of the cleaning section, and the brush bristles guide the light, allowing it to act on the functional ingredients in the oral hygiene product during brushing to achieve effects such as whitening.

[0031] However, due to limitations in the bristle implantation process, the light emission efficiency is low when the light-emitting element is placed at the base of the cleaning section. On one hand, in copper-based bristle implantation, the metal sheet used to fix the bristles can easily block the light emitted from the light-emitting element, making it difficult for the light to effectively enter the bristles. On the other hand, in copper-free bristle implantation, the cleaning section is fixed to the carrier plate by heat fusion. The heat-fused area between the carrier plate and the cleaning section has poor light transmittance, weakening the light emission intensity of the oral cleaning component. Therefore, there is significant light loss in the light path from the light-emitting element to the light-emitting end of the bristles, resulting in insufficient effective light energy to actually act on the functional ingredients, thus affecting the overall effect of light-assisted whitening.

[0032] To address the aforementioned technical problems, embodiments of this application provide an oral hygiene component and an oral hygiene device. In a first aspect, embodiments of this application provide an oral hygiene component; please refer to… Figures 1 to 3 The oral cleaning device 1 includes a support part 11, multiple cleaning parts 20 and a light source assembly 30. The support part 11 has a first surface 110, and the multiple cleaning parts 20 are disposed on the first surface 110 and are spaced apart. During the oral cleaning process, the multiple cleaning parts 20 can act on the tooth surface, tooth gaps and gum margins simultaneously or alternately, and repeatedly brush and clean the teeth under the drive of the support part 11.

[0033] A light source assembly 30 is disposed along the first direction X on the side of the support portion 11 facing away from the first surface 110. The light source assembly 30 includes a plurality of light-emitting elements 31. The portion of the support portion 11 located between two adjacent cleaning portions 20 is translucent. Each light-emitting element 31 is disposed corresponding to the gap between two adjacent cleaning portions 20. The light emitted by the light-emitting element 31 passes through the support portion 11 and is at least partially projected onto the oral cleaning agent attached to the cleaning portion 20, thereby changing the composition of the oral cleaning agent. At the position corresponding to the light-emitting element 31 in the direction perpendicular to the first direction X, the distance between two adjacent cleaning portions 20 is L, where L satisfies: L≤4mm.

[0034] It should be noted that the tufting process has little impact on the light transmittance of the portion of the support part 11 located between two adjacent cleaning parts 20. The portion of the support part 11 located between two adjacent cleaning parts 20 can easily achieve high light transmittance: when the cleaning part 20 is fixed to the first surface 110 of the support part 11 using a copper tufting process, the metal sheet is mainly distributed in the root region of the cleaning part 20, while the gap region between two adjacent cleaning parts 20 is not blocked by the metal sheet, making it easier for the support part 11 to maintain good light transmittance. When a copper-free tufting process is used, the root of the cleaning part 20 needs to be fixed by heat fusion. The heat-fused area easily reduces local light transmittance, while the gap region between two adjacent cleaning parts 20 is less affected by heat fusion and can also maintain good light transmittance. Based on this, this embodiment of the application, by correspondingly placing the light-emitting element 31 at the gap position between two adjacent cleaning parts 20, allows light to be emitted from the area with better light transmittance in the support part 11, effectively reducing the light blocking or absorption problems caused by the tufting process, thereby improving the overall light emission efficiency of the oral cleaning component 1.

[0035] Furthermore, by controlling the distance L between two adjacent cleaning sections 20 to satisfy the above-mentioned condition, the multiple cleaning sections 20 are arranged in a relatively dense distribution on the first surface 110. Under the action of the cleaning sections 20, the oral cleanser forms sufficient cleaning foam, ensuring the cleaning effect. At the same time, a gap space with controlled size is formed between adjacent cleaning sections 20. The cleaning foam can stably fill the gaps between adjacent cleaning sections 20 and the gaps between the bristles within the cleaning section 20. The light emitted by each light-emitting element 31, after passing through the light-transmitting part of the carrier 11, can directly act on the cleaning foam remaining in these gaps, thereby improving the contact efficiency between light and functional ingredients, enhancing the activation effect of blue light on functional ingredients, improving light utilization without relying on the light guide of the bristles, and enhancing the whitening effect.

[0036] Except for the location where the light-emitting element 31 is provided, the spacing between the cleaning parts 20 at other locations may or may not meet the above-mentioned limitations, and this application does not impose any particular limitations. Of course, it is preferred that the spacing between the cleaning parts 20 at all locations all satisfy L≤4mm to ensure thorough cleaning of the oral cavity.

[0037] The cleaning section 20 can employ a bristle bundle, which includes multiple bristles. These bristles are attached to the first surface 110 of the support section 11 using either a copper-bonded or copper-free bristle-bonded process. Furthermore, the spacing L is set to satisfy 2mm ≤ L ≤ 4mm, which also considers the feasibility of the manufacturing process. When the spacing L < 2mm, the space between adjacent cleaning sections 20 is too narrow, making it difficult to reserve sufficient operating space for the bristle-bonding needles, metal sheets, or hot-melt structures during the bristle-bonding process, easily increasing manufacturing difficulty and reducing the yield rate.

[0038] In some embodiments, the light-emitting element 31 is configured to correspond to the gap between two adjacent cleaning parts 20, thereby maximizing the light transmittance of the gap area of ​​the support part 11 and achieving full light output.

[0039] In other embodiments, a portion of the light-emitting element 31 is configured to correspond to the gap between two adjacent cleaning sections 20, while another portion is configured to correspond to the cleaning section 20. In actual manufacturing, the large size of the light-emitting element 31 and processing errors may prevent the light-emitting element 31 from perfectly corresponding to the gap. However, as long as a portion of the light-emitting element 31 corresponds to the gap between two adjacent cleaning sections 20, at least some light can pass through the support portion 11 and be directed to the gap between the adjacent cleaning sections 20, thus achieving the desired light-assisted effect.

[0040] Furthermore, since the light source assembly 30 is disposed along the first direction X on the side of the support portion 11 facing away from the first surface 110, the support portion 11 can form a physical barrier for the multiple light source assemblies 30, preventing the light source assembly 30 from being directly exposed to the oral environment, reducing the situation where stains such as cleaning foam, tooth stains or oral impurities directly adhere to the surface of the light-emitting element 31, thereby reducing the impact of stains on the light emission effect of the light-emitting element 31, which is conducive to maintaining the light emission stability and light intensity consistency of the light-emitting element 31 in the long term, and further improving the reliability and user experience of the oral cleaning device 1 during long-term use.

[0041] In some embodiments, the light-emitting element 31 is configured to emit light toward the support portion 11. For example, the main axis of the light emitted by the light-emitting element 31 extends along a first direction X, and the light emission angle of the light-emitting element 31 is α, where α satisfies: 0 < α ≤ 30°. The light emission angle α refers to the angle between the regions on both sides of the main axis of the light beam where the luminous intensity reaches 50% of its maximum value. By controlling the light emission angle α within a range not exceeding 30°, the light emitted by the light-emitting element 31 can be more concentrated, thereby reducing light intensity loss due to light scattering and improving the utilization rate of effective light energy.

[0042] Optionally, please refer to Figure 4The light-emitting element 31 includes a light-emitting body 301 and a light-transmitting shell 302. The light-transmitting shell 302 encapsulates the light-emitting body 301. The outer surface of the light-transmitting shell 302 facing the cleaning part 20 is hemispherical to focus the light emitted by the light-emitting body 301. For example, the light-emitting element 31 can be a round-headed LED.

[0043] like Figures 5-8 As shown in the embodiment of this application, the area on the first surface 110 where the light emitted by each light-emitting element 31 is projected is the projection area 310. It should be noted that the boundary of the projection area 310 (the dotted line in the figure) is only for clear illustration of the projection area 310 and does not represent the actual boundary shape and size of the area. In actual products, due to the influence of structures such as hair follicles and light scattering, the projection area 310 may present an irregular shape. In particular, by arranging the relative positions of the multiple cleaning parts 20 and the multiple light-emitting elements 31, the light emitted by the multiple light-emitting elements 31 can form areas of different shapes on the first surface 110 to adapt to different usage requirements.

[0044] like Figure 5 As shown, in some embodiments, the projection areas 310 of the multiple light-emitting elements 31 are independent of each other in order to obtain a larger irradiation area. Although each projection area 310 is independent of each other in a static state, during the brushing process, the oral cleaning element 1 moves continuously relative to the tooth surface, and the irradiated cleaning foam is displaced and turned over, thereby covering and acting on the surface of each tooth to achieve the overall cleaning and whitening effect of the teeth.

[0045] In other embodiments, the projection areas 310 of any two adjacent light-emitting elements 31 partially overlap. Correspondingly, the light emitted by multiple light-emitting elements 31 forms a relatively continuous irradiation area in space. The cleaning foam irradiated by the light is continuous and more concentrated in space. These continuous and concentrated cleaning foams move with the oral cleaning device 1 and act on the surface of the teeth. Their movement trajectories are more likely to overlap, thereby covering the entire tooth surface. The risk of local areas not being in contact with the irradiated cleaning foam is relatively small.

[0046] Optionally, multiple light-emitting elements 31 are arranged along a preset direction. Along this preset direction, the projection area 310 of each light-emitting element 31 overlaps only with the projection area 310 of the adjacent light-emitting element 31, thereby forming a continuous and regular area along the preset direction. The multiple light-emitting elements 31 can be arranged linearly, with the linear arrangement direction forming an angle with the moving direction of the oral cleaning component 1. The multiple light-emitting elements 31 form an irradiation area that sweeps across more tooth surfaces as the oral cleaning component 1 moves. For example, the multiple light-emitting elements 31 are arranged along the length of the support portion 11, and the light emitted from them forms a continuous irradiation area along the length of the support portion 11. The cleaning foam within the irradiation area contacts the tooth surface during the movement of the oral cleaning component 1.

[0047] Multiple light-emitting elements 31 can also be arranged in a ring, with at least one cleaning section 20 disposed within the area enclosed by the multiple light-emitting elements 31. In this case, the light emitted by the multiple light-emitting elements 31 forms a continuous ring-shaped irradiation area, and the size of the irradiation area is expanded in multiple directions. For example, as... Figure 6 As shown, multiple light-emitting elements 31 are arranged in a racetrack-like circular shape. The irradiation area not only extends along the length of the support portion 11, but also increases in size along the width of the support portion 11. This increases the coverage width of the irradiation area in different directions, which is beneficial for the cleaning foam in the irradiation area to achieve a more comprehensive and uniform effect on the tooth surface.

[0048] Optionally, at least three light-emitting elements 31 form a group of light-emitting units 32. The projection areas 310 of multiple light-emitting elements 31 in the same group of light-emitting units 32 overlap, reducing the empty areas between multiple projection areas 310. Furthermore, by arranging multiple groups of light-emitting units 32 so that the projection areas 310 formed by adjacent light-emitting units 32 overlap, the coverage of the target surface in the middle of the support portion 11 is improved, and the irradiated area is more continuous and concentrated in space. Figure 7 As shown, three light-emitting elements 31 form a group of light-emitting units 32. Adjacent groups of light-emitting units 32 share some light-emitting elements 31 to reduce the empty area between the projection areas 310 of adjacent light-emitting units 32. Figure 8 As shown, four light-emitting elements 31 form a group of light-emitting units 32, and the projection areas 310 of two adjacent groups of light-emitting units 32 overlap with each other, thereby forming a more concentrated and continuous illumination area.

[0049] In some embodiments, a plurality of cleaning portions 20 adjacent to a plurality of light-emitting elements 31 of the same light-emitting unit 32 form a cleaning unit 21, and the gaps between the plurality of cleaning portions 20 of the same cleaning unit 21 are covered by the projection area 310 of the plurality of light-emitting elements 31 of the same group of light-emitting units 32. By correspondingly configuring the light-emitting units 32 and the cleaning units 21, light is stably applied to the gap areas between the cleaning portions 20 and the cleaning foam in the gap areas.

[0050] In some embodiments, at least some of the cleaning units 21 are arranged along the second direction Y, or at least some of the cleaning units 21 are arranged along the third direction Z, or at least some of the cleaning units 21 are arranged along both the second direction Y and the third direction Z. The first direction X, the second direction Y, and the third direction Z are all perpendicular to each other. By arranging the cleaning units 21 in different mutually perpendicular directions, the multiple cleaning parts 20 act on the tooth surface, interdental spaces, and gingival margin, thereby improving the comprehensiveness of cleaning coverage.

[0051] In some embodiments, the support portion 11 includes a first region 101 and a second region 102 disposed around the first region 101, and the plurality of cleaning portions 20 include a plurality of first cleaning portions 22 disposed in the first region 101 and a plurality of second cleaning portions 23 disposed in the second region 102.

[0052] The support part 11 is generally made of hard plastic material. In order to avoid the hard support part 11 hitting the skin inside the mouth and causing discomfort when the user uses the oral cleaning device 1, the oral cleaning device 1 is also provided with a soft plastic part 40. The soft plastic part 40 covers part of the surface of the support part 11 to improve comfort and safety during use.

[0053] The plurality of cleaning parts 20 also include a soft rubber cleaning part 24, wherein a portion of the soft rubber part 40 is disposed on the first surface 110 of the support part 11 and located on opposite sides of the first region 101 to form the soft rubber cleaning part 24, that is, the soft rubber cleaning part 24 is located in the second region 102 and is correspondingly located on opposite sides of the first region 101.

[0054] It should be noted that the soft rubber part 40 is opaque, therefore the light-emitting element 31 needs to avoid the soft rubber part 40 and the soft rubber cleaning part 24 when it is set. Accordingly, the light-emitting element 31 is mainly arranged corresponding to the first region 101. In addition, the first region 101 is located in the middle region of the support part 11. The first region 101 usually corresponds to the area where the oral cleaning component 1 has a high frequency of contact with the tooth surface and a long residence time during brushing. The cleaning foam in this area is more easily squeezed and renewed repeatedly. Therefore, the multiple light-emitting elements 31 are mainly arranged to correspond to the gap between the first cleaning part 22 and the adjacent cleaning part 20, so that the light emitted by the light-emitting element 31 mainly covers the first region 101, thereby improving the light coverage of the first region 101. The cleaning foam in the first region 101 is continuously under effective light, which is conducive to the full activation of functional components. Then, during the reciprocating motion of the oral cleaning component 1, the activated functional components are carried to a larger area of ​​the tooth surface by means of the flow and diffusion of the cleaning foam, so as to achieve the stable performance of light-assisted effect in the overall cleaning process.

[0055] In some embodiments, at least some of the light-emitting elements 31 are configured to correspond to the gap between two adjacent first cleaning parts 22, or at least some of the light-emitting elements 31 are configured to correspond to the gap between adjacent first cleaning parts 22 and second cleaning parts 23, or some of the light-emitting elements 31 are configured to correspond to the gap between two adjacent first cleaning parts 22 and the gap between adjacent first cleaning parts 22 and second cleaning parts 23.

[0056] At least a portion of the light-emitting element 31 is positioned in the gap between the first cleaning section 22 and the adjacent soft rubber cleaning section 24. On one hand, the soft rubber cleaning section 24 can clean the gums and adjacent soft tissues during oral cleaning while also providing cushioning and protection, reducing irritation from hard structures. On the other hand, the light-emitting element 31, positioned in the gap between the first cleaning section 22 and the soft rubber cleaning section 24, allows light to pass through a well-transmitted area in the support section 11 and directly act on the cleaning foam in that area, ensuring both effective illumination and user comfort. Furthermore, compared to the cleaning section 20 composed of bristles, the soft rubber cleaning section 24, integrally molded from soft rubber, has better overall integrity, enabling a comprehensive wiping of the tooth surface, facilitating the removal of reactants produced by the whitening oxidation reaction, and allowing users to easily observe the whitening effect.

[0057] In this embodiment, along the third direction Z, the support portion 11 includes a first end near the handle during use and a second end opposite to the first end, wherein the distance between the soft rubber cleaning portion 24 and the second end is smaller than the distance between the soft rubber cleaning portion 24 and the first end. Figure 2 As shown, the upper end of the support portion 11 is the second end, and the lower end is the first end. That is, in the third direction Z, the soft rubber cleaning portion 24 is closer to the upper end of the support portion 11. This design allows the soft rubber cleaning portion 24 to more easily reach the molars when the oral cleaning component 1 is inserted deep into the oral cavity, which is beneficial for cleaning the molars.

[0058] The soft rubber cleaning part 24 can be integrally molded with the soft rubber part 40. In order to ensure a stable connection between the soft rubber cleaning part 24 and the support part 11, a snap-fit ​​structure such as a dovetail groove can be provided on the support part 11 so that part of the soft rubber cleaning part 24 can be snapped into the snap-fit ​​structure to achieve fixation.

[0059] In this embodiment, the cleaning part 20 may include multiple bristles, and the first surface 110 of the supporting part 11 has multiple bristle implantation holes. The multiple bristles of each cleaning part 20 are fixed in one bristle implantation hole, and the multiple bristles clean the user's teeth. For example, the first cleaning part 22 and the second cleaning part 23 both include multiple bristles. Through the bending, friction and squeezing action of the bristles, plaque and food debris can be removed, thereby completing the basic cleaning function of the oral cleaning device 1.

[0060] In some embodiments, the portion of the carrier 11 corresponding to the cleaning portion 20 is translucent, and the bristles are translucent. The light emitted by the light-emitting element 31 passes through the carrier 11 and is emitted through the bristles, which can directly guide the light to the tip of the bristles and the location of the cleaning foam, thereby improving the light transmission efficiency and utilization rate.

[0061] In one feasible embodiment, the bristles include an inner light-transmitting core and an outer opaque light-emitting element 31 covering the core in the radial direction. Part of the light emitted by the light-emitting element 31 can be conducted along the light-transmitting core of the bristles and emitted at the end of the bristles away from the support portion 11. During tooth cleaning, the bristle tip directly acts on the tooth surface, and the light emitted from the tip can catalyze the oral cleaning agent or cleaning foam coated on the tooth surface. Simultaneously, the surface of the opaque outer layer of the bristles can reflect light, causing the light to reflect multiple times in the area between adjacent bristles, thereby catalyzing the cleaning foam filling the spaces between the bristles. The catalyzed cleaning foam then acts on the tooth surface, which helps to improve the overall cleaning effect.

[0062] In another feasible implementation, the bristles are made of a light-transmitting material, that is, both the core and the outer layer of the bristles are light-transmitting along their radial direction, so that light can not only be emitted from the tip of the bristles, but also diffuse around through the outer surface of the bristles, thereby simultaneously irradiating the tooth surface in contact with the tip of the bristles and the cleaning foam around the bristles, which helps to expand the illumination range and improve the coverage effect of light-assisted cleaning.

[0063] In other embodiments, the bristles can be made of an opaque material. In this case, by setting the bristle surface as a reflective surface to reflect light between adjacent cleaning sections 20, even if the light encounters obstruction from the bristles during propagation, it can still exit the oral cleaning component 1 through multiple reflections on the bristle surface, thereby improving the uniformity of illumination on the oral cleaning component 1. In actual manufacturing, the cleaning section 20 uses white nylon bristles to further enhance the reflective effect, causing the light to be refracted and scattered multiple times on the bristle surface, and evenly distributed between the brush head and the cleaning foam. Of course, the bristles can also be made of other colors and materials; this is not limited.

[0064] Please see Figure 9 and Figure 10 In this embodiment, the carrier portion 11 includes a light-transmitting portion 111, which has an incident surface 1111 and an exit surface 1112 disposed opposite to each other along a first direction X. The light emitted by the light-emitting element 31 travels from the incident surface 1111 to the exit surface 1112, and the illuminance of the light reaching the exit surface 1112 is greater than 50 mW / cm². 2 After being transmitted through the carrier 11, the light intensity of the light-emitting element 31 acting on the cleaning foam is greater than 30mW / cm². 2 Thus, the light still has enough energy to act on the cleaning foam, activating the functional ingredients in the oral cleanser and achieving the desired light-assisted effect.

[0065] In some embodiments, the light-transmitting portion 111 of the carrier portion 11 may be a partially light-transmitting structure: the light-transmitting portion 111 corresponds to the portion of the carrier portion 11 located between two adjacent cleaning portions 20, and the first surface 110 of the carrier portion 11 includes a plurality of light-incident surfaces 1111, so that the light emitted by the light-emitting element 31 can be transmitted through the light-transmitting portion 111 to the gap area between the cleaning portions 20.

[0066] In other embodiments, the support portion 11 can also be designed to be entirely light-transmitting, with the support portion 11 being the light-transmitting portion 111 and the first surface 110 of the support portion 11 being the light-incident surface 1111. This simplifies the structure of the support portion 11 and facilitates its integral molding manufacturing. Simultaneously, some of the light emitted by the light-emitting element 31 can pass through the support portion 11 and be emitted through the brush filaments, further improving light utilization efficiency and light coverage.

[0067] In some embodiments, the light transmittance of the light-transmitting part 111 is τ, where τ satisfies: τ > 85%. In actual products, light intensity is attenuated after passing through the carrier part 11. By controlling the light transmittance τ of the light-transmitting part 111 to be greater than 85%, the light loss of the light emitted by the light-emitting element 31 when passing through the light-transmitting part 111 is small, and thus the light intensity reaching the light-emitting surface 1112 meets the preset threshold.

[0068] In some embodiments, the wavelength of the light emitted by the light-emitting element 31 is λ, where λ satisfies: 400nm ≤ λ ≤ 500nm. For example, the value of λ can be 410nm. By defining the wavelength range of the light, the light-emitting element 31 emits blue light of a preset wavelength, which can effectively activate the functional ingredients in the oral cleanser.

[0069] Optionally, technicians can select the emission wavelength of the light-emitting element 31 according to actual usage needs. For example, some of the light-emitting elements 31 can be set to emit light of other wavelengths. By combining light-emitting elements 31 with different wavelengths, the oral cleaning device 1 can simultaneously achieve multiple functions. For example, some of the light-emitting elements 31 can be set to emit blue light and others can emit red light. The blue light catalyzes the functional components in the cleaning foam to achieve a whitening effect, while the red light promotes blood circulation or enhances antibacterial effects.

[0070] Please continue reading. Figure 9 and Figure 10 In some embodiments, the light-incident surface 1111 is provided with a light-transmitting groove 1113 corresponding to the light-emitting element 31, and the light-emitting element 31 is provided with a light-transmitting groove 1113. In this way, a portion of the light-emitting element 31 is disposed in the light-transmitting groove 1113, thereby reducing the thickness of the light-transmitting portion 111 along the first direction X, shortening the propagation path of light in the light-transmitting portion 111, and reducing light loss.

[0071] Optionally, the wall of the light-transmitting groove 1113 is an arc-shaped surface. The arc-shaped surface has a certain light-focusing effect. The light emitted by the light-emitting element 31 is more concentrated on the light-emitting surface 1112 under the action of the arc-shaped surface, thereby increasing the light intensity of the light emitted from the carrier part 11.

[0072] In some embodiments, the oral cleaning component 1 further includes a reflector disposed toward the support portion 11, and the reflector is used to perform secondary reflection of the light reflected by the support portion 11, so that the secondary reflected light is directed toward the surface of the support portion 11, thereby improving light utilization efficiency.

[0073] The light source assembly 30 also includes a circuit board 33, with a plurality of light-emitting units 32 disposed on the surface of the circuit board 33 facing the cleaning part 20. A reflector is disposed on at least one of the circuit board 33 and the carrier part 11. For example, the reflector is disposed on the side of the circuit board 33 facing the cleaning part 20, thereby performing secondary reflection of the light reflected by the carrier part 11. Alternatively, the reflector is disposed on the carrier part 11, and the portion of the carrier part 11 where the cleaning part 20 is mounted is positioned opposite the reflector, thereby performing secondary reflection of the light reflected by the carrier part 11.

[0074] In some embodiments, the oral cleaning device 1 includes a cover 12, which is mounted on a support portion 11, and the support portion 11 and the cover 12 enclose a receiving cavity 100. The receiving cavity 100 provides installation space for the internal structure of the oral cleaning device 1, wherein the light source assembly 30 is disposed in the receiving cavity 100.

[0075] In some embodiments, the cover 12 is sealed to the support portion 11 to prevent water or dirt from entering the receiving cavity 100 during use of the oral cleaning device 1. For example, the support portion 11 has a first opening groove, and the cover 12 has a second opening groove. The cover 12 covers the support portion 11, and the first and second opening grooves together form the receiving cavity 100. A sealant is provided at the connection between the cover 12 and the support portion 11 to achieve a sealed connection. Alternatively, the support portion 11 has a first opening groove on its surface opposite to the first surface 110 along the first direction X. The cover 12 is embedded in the first opening groove to form the receiving cavity 100. A sealant is provided at the connection between the cover 12 and the support portion 11 to achieve a sealed connection.

[0076] Optionally, the hair-planting holes of the support part 11 are blind holes, and the support part 11 has a first opening groove on the surface opposite to the first surface 110 along the first direction X. The cover 12 is embedded in the first opening groove to form a receiving cavity 100. In this way, the connection between the support part 11 and the cover 12 is located on the back of the support part 11, and the front of the support part 11 has an integral seamless structure with good waterproof performance.

[0077] In some embodiments, the soft rubber component 40 covers the cover body 12 and the support portion 11, wherein the soft rubber component 40 covers at least the connection between the cover body 12 and the support portion 11, thereby forming an additional sealing protection for the accommodating cavity 100, inhibiting water damage to the light source assembly 30 caused by moisture intrusion into the accommodating cavity 100, and further improving the durability and safety of use of the oral cleaning component 1. It is understood that the soft rubber component 40 only covers a portion of the surface of the support portion 11, while at least a portion of the first surface 110 of the support portion 11 is exposed to the external space, so as to ensure that the light emitted by the light-emitting component 31 passes through the support portion 11 and is emitted smoothly to achieve the expected irradiation effect.

[0078] Secondly, this application also provides an oral cleaning device, which can be an electric toothbrush. The oral cleaning device includes a handle and an oral cleaning component 1. The handle includes a main control board and a motor. The oral cleaning component 1 is installed on the handle, and at least one of the main control board and the motor is electrically connected to the light source assembly 30 so that the light-emitting element 31 of the light source assembly 30 can be lit when the oral cleaning device is working.
