Description

Technical Field

[0001] This application relates to the field of personal care technologies, and particularly to an oral care element and an oral cleaner. Background Art

[0002] With the improvement of oral health awareness, electric toothbrushes have become the preferred oral cleaners for many families. An electric toothbrush drives an oral care element to vibrate at a high frequency through a built-in motor. This action can quickly break down toothpaste into fine foam, achieving in-depth cleaning of tooth gaps and effectively cleaning the tooth surface.

[0003] The oral care element of a related oral cleaner may include a contact element carrier and a brush handle with a support base. The brush handle is connected to the contact element carrier through the support base. Among them, the contact element carrier and the support base are usually hard seats. During brushing, the contact element carrier and the support base are prone to collide with teeth during high-speed vibration, resulting in the phenomenon of "hitting teeth", which affects the user experience. Summary of the Utility Model

[0004] The purpose of this application is to provide an oral care element and an oral cleaner, which can improve the comfort of brushing teeth while optimizing the production process.

[0005] To achieve the above purpose, this application on the one hand provides an oral care element. The oral care element at least includes a brush handle, a contact element carrier, and a surface covering. Among them, the brush handle extending along the main extension line direction has a support base and a first end and a second end oppositely arranged on the main extension line. The support base is located at the second end of the brush handle; the contact element carrier is provided with a plurality of tufting through holes for installing brush filaments. The contact element carrier abuts against the support base along a direction perpendicular to the main extension line, and the support base blocks the plurality of tufting through holes from communicating with the external environment through the back surface of the contact element carrier; the surface covering has a soft texture. The surface covering covers the side surfaces of the whole formed by the support base and the contact element carrier, and covers at least part of the back surface of the support base and at least part of the front surface of the contact element carrier to connect the support base and the contact element carrier.

[0006] Optionally, an installation groove is provided on the back surface of the contact element carrier; the support base is inserted into the installation groove, and the back surface of the support base is substantially flush with the back surface of the contact element carrier. The side surface of the contact element carrier forms the side surface of the whole formed by the support base and the contact element carrier.

[0007] Optionally, the back surface of the contact element carrier is substantially flush with the front surface of the support base, and the side surface of the contact element carrier and the side surface of the support base together form the side surface of the whole formed by the support base and the contact element carrier.

[0008] Optionally, an attachment groove extending inward from the side surface of the contact element carrier is provided on the front surface of the contact element carrier; the surface covering member is filled in the attachment groove to cover a part of the front surface of the contact element carrier.

[0009] Optionally, the attachment groove includes a continuous annular groove extending along the edge of the contact element carrier.

[0010] Optionally, the attachment groove further includes a plurality of inward extension grooves, and the inward extension grooves extend inward from the side wall surface of the annular groove.

[0011] Optionally, there are at least four of the inward extension grooves, and the inward extension grooves are respectively provided on the opposite sides of the side wall surface of the annular groove along the main extension line direction, and the inward extension grooves are respectively provided at the opposite ends of the side wall surface of the annular groove along the main extension line.

[0012] Optionally, the attachment groove is configured as a plurality of inward extension grooves, and the plurality of inward extension grooves are arranged at intervals along the edge of the contact element carrier.

[0013] Optionally, a concave cavity communicating with a plurality of the hair implanting through holes is provided on the back surface of the contact element carrier, and the side wall of the concave cavity forms a continuous surrounding edge extending along the edge of the contact element carrier; the back surface of the contact element carrier is attached to the front surface of the support base so that the support base blocks the plurality of hair implanting through holes from communicating with the external environment through the back surface of the contact element carrier.

[0014] Optionally, the contact element carrier is provided with an anti-fooling member exceeding the back surface of the contact element carrier, and the front surface of the support base is provided with a mating groove adapted to the anti-fooling member; alternatively, the back surface of the surrounding edge is provided with a mating groove, and the front surface of the support base is provided with an anti-fooling member adapted to the mating groove.

[0015] Optionally, the end of the brush filament cluster passing through the back surface of the contact element carrier is fixed by melting.

[0016] To achieve the above object, on the other hand, the present application further provides an oral cleaner, and the oral cleaner includes a holding portion and the above-mentioned oral care element; the oral care element is installed on the holding portion to drive the oral care element to move through a driving device on the holding portion, or to enable an external force to drive the oral care element to move through the holding portion.

[0017] It can be seen that, for the technical solution provided by the present application, the surface covering member simultaneously wraps around the side surfaces of the overall formed by the support base and the contact element carrier, at least part of the back surface of the support base, and at least part of the front surface of the contact element carrier, thereby increasing the bonding area between the surface covering member and the support base and the contact element carrier, and thus increasing the bonding strength between the surface covering member and the support base and the contact element carrier. Furthermore, the bonding strength is sufficient to firmly connect the support base and the contact element carrier, without the need to pre-connect the support base and the contact element carrier and then wrap the surface covering member, simplifying the production process and reducing the production cost.

[0018] At the same time, the surface covering member simultaneously wraps around the side surfaces of the overall formed by the support base and the contact element carrier, at least part of the back surface of the support base, and at least part of the front surface of the contact element carrier. During toothbrushing, the surface covering member can block between the support base and the contact element carrier and the inner wall of the oral cavity and the teeth, thereby playing a buffering role between the support base and the contact element carrier and the inner wall of the oral cavity and the teeth, avoiding the direct collision of the support base and the contact element carrier with the teeth and the occurrence of the phenomenon of "hitting the teeth", improving the comfort of the user's oral cavity and the oral care element, and further improving the user experience. Moreover, the surface covering member of the present application covers more surfaces of the support base and the contact element carrier, and its blocking area is more comprehensive, with better use comfort.

[0019] In addition, the support base can also block a number of hair implanting through holes from communicating with the external environment through the back surface of the contact element carrier. In this way, during the forming process of the surface covering member, or when pouring the liquid for forming the surface covering member, it is possible to avoid the overflow of the liquid through the hair implanting through holes to the front surface of the contact element carrier, resulting in product quality problems.

[0038] The oral care element of an electric toothbrush in the related art is usually composed of a contact element carrier and a support base. The contact element carrier fixes the brush filament cluster and is connected to the brush handle through the support base. Among them, the contact element carrier and the support base are often made of hard materials to ensure that the high-frequency vibration from the built-in motor can be effectively transmitted to the brush filament cluster and to ensure the structural stability and durability.

[0039] However, the use of such hard materials also brings certain problems. When brushing teeth with an electric toothbrush, due to the high-speed vibration of the oral care element, the contact element carrier and the support base may collide with the teeth. This collision is called the "tooth hitting" phenomenon, which may not only cause unnecessary pressure on the teeth, but also affect the user experience, and even lead to gum discomfort or tooth sensitivity.

[0040] To solve this problem, referring to Figure 1 , the inventors of the present application have tried to wrap a soft protective layer such as soft glue on the sides and back of the integral formed by connecting the support base 110 and the contact element carrier 200, so as to reduce the direct collision of hard materials such as the support base 110 and the contact element carrier 200 with oral organs such as teeth, and improve the comfort and user experience. However, such a setting requires connecting the support base 110 and the contact element carrier 200 by ultrasonic welding or gluing first, and then covering the back and sides of the integral formed by the support base 110 and the contact element carrier 200 with soft glue material by a rubber coating method, and the production process is relatively complex. To further optimize the production process and the brushing comfort, the inventors of the present application have tried to wrap the soft glue on the front of the contact element carrier 200. This not only further reduces the possibility of direct contact between the hard contact element carrier 200 and the user's oral cavity, but also enables the soft glue to directly and reliably connect the support base 110 and the contact element carrier 200 together. Thus, during assembly, it is not necessary to connect the support base 110 and the contact element carrier 200 together in advance and then cover them with soft glue. Furthermore, the support base 110 can be used to block the hair planting through hole 240 on the contact element carrier 200 from communicating with the external environment through the back of the contact element carrier 200. In this way, when pouring the liquid for forming the surface soft glue, it can be avoided that the liquid overflows to the front of the contact element carrier 200 through the hair planting through hole 240, resulting in product defects. In this way, while improving the brushing comfort, the production process can be optimized, the production cost can be reduced, and the product yield can be increased.

[0041] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application.

[0042] The present application provides an oral care element 1000, which can be detachably or fixedly connected to the holding part 2000 of an oral cleaner (manual toothbrush or electric toothbrush). Taking the case where the oral care element 1000 is detachably connected to the holding part 2000 of an electric toothbrush as an example, the user can hold the holding part 2000 to drive the oral care element 1000 to perform a cleaning operation, and the holding part 2000 can also drive the oral care element 1000 to vibrate to improve the cleaning effect. When the oral care element 1000 is damaged, it is also convenient to replace the oral care element 1000 to reduce the replacement cost.

[0043] Specifically, please refer to Figures 2 to 5 as shown. In an implementable embodiment, the oral care element 1000 may include a brush handle 100, a contact element carrier 200, and a surface covering 300. Among them, the brush handle 100 extends along the main extension line direction. The brush handle 100 has a support seat 110 and a first end 120 and a second end 130 that are oppositely arranged on the main extension line. The support seat 110 is located at the second end 130 of the brush handle 100. The support seat 110 is used to attach the contact element carrier 200 to provide support for the contact element carrier 200 and transmit the vibration energy from the holding part 2000. The first end 120 of the brush handle 100 is used to connect to the holding part 2000. It should be noted that the main extension line defined in the present application refers to the straight line formed by the main extension direction of the overall structure of the brush handle 100 (please refer to Figure 2 as shown). For example, when the brush handle 100 is substantially cylindrical, the main extension line of the brush handle 100 is the axis of the brush handle 100.

[0044] In practical applications, a clamping bracket 140 may be provided at the first end 120 of the brush handle 100. The clamping bracket 140 is used to be clamped or press-fitted with the output shaft of the holding part 2000 to connect the oral care element 1000 and the holding part 2000. When the oral care element 1000 is subjected to a force in the direction away from the holding part 2000, the output shaft of the holding part 2000 can be separated from the clamping bracket 140, facilitating the replacement of the oral care element 1000. Among them, the clamping bracket 140 can be connected to the first end 120 of the brush handle 100 by means of hot melting, ultrasonic welding, etc., or integrally injection-molded with the brush handle 100. The clamping bracket 140 can also be clamped on the first end 120 of the brush handle 100 by means of a snap-fastening groove. However, it should be noted that when the clamping bracket 140 is clamped on the first end 120 of the brush handle 100 by means of a snap-fastening groove, an anti-rotation protrusion or anti-rotation groove matching with the clamping bracket 140 should be provided at the first end 120 of the brush handle 100 to limit the rotation of the clamping bracket 140 relative to the first end 120 of the brush handle 100, thereby avoiding relative sliding between the clamping bracket 140 and the brush handle 100 when the output shaft of the holding part 2000 drives the brush handle 100 to swing reciprocally, which may affect normal oral care operations. Of course, the first end 120 of the above-mentioned brush handle 100 can also be directly fixedly connected to the holding part 2000, thus forming an integral structure with the holding part 2000.

[0045] In this embodiment, the contact element carrier 200 is provided with a plurality of tufting through-holes 240 for installing the brush filament clusters 400. The tufting through-holes 240 penetrate through the front and back surfaces of the contact element carrier 200, and the brush filament clusters 400 are limited in the radial direction of the through-hole by the tufting through-holes 240. The contact element carrier 200 abuts against the support seat 110 in a direction perpendicular to the main extension line. In this way, the support seat 110 can support the entire surface of the contact element carrier 200 close to the support seat 110, so as to improve the overall strength of the head of the oral care element 1000, avoid bending damage, and thus improve the service life of the oral care element 1000. At the same time, the support seat 110 supports the entire surface of the contact element carrier 200 close to the support seat 110, and can also increase the contact area between the brush handle 100 and the contact element carrier 200, so that the vibration energy from the brush handle 100 can be efficiently and evenly transmitted to the contact element carrier 200, achieving a more prominent and comprehensive vibration effect, thereby improving the cleaning effect.

[0046] In practical applications, the brush handle 100 can drive the contact element carrier 200 to vibrate through the support base 110. In this way, the contact element carrier 200 can transfer the vibration it receives to the brush filament cluster 400 to drive the brush filament cluster 400 to vibrate. Thus, the vibrating brush filament cluster 400 can help transfer the toothpaste and moisture on the brush filament cluster 400 to the tooth surface and the gingival margin better, so as to more thoroughly remove food residues, bacteria, and dental plaque. Moreover, the vibrating brush filament cluster 400 can also more easily enter the tooth gaps and the vicinity of the gingival line, improving the cleaning range.

[0047] In this embodiment, the surface covering 300 has a soft texture. The surface covering 300 covers the side surface of the whole formed by the support base 110 and the contact element carrier 200, and covers at least part of the back surface of the support base 110 and at least part of the front surface of the contact element carrier 200, thereby connecting the support base 110 and the contact element carrier 200. In other words, in the present application, the support base 110 and the contact element carrier 200 are connected by being covered by the surface covering 300.

[0048] It is worth mentioning that in the present application, it is also by the way that the surface covering 300 covers the side surface of the whole formed by the support base 110 and the contact element carrier 200, at least part of the back surface of the support base 110, and at least part of the front surface of the contact element carrier 200, that the bonding area between the surface covering 300 and the support base 110 and the contact element carrier 200 is increased, thereby increasing the bonding strength between the surface covering 300 and the support base 110 and the contact element carrier 200. Furthermore, the bonding strength is sufficient to firmly connect the support base 110 and the contact element carrier 200, without the need to connect the support base 110 and the contact element carrier 200 in advance and then cover the surface covering 300, simplifying the production process and reducing the production cost.

[0049] Moreover, it can be understood that the surface covering 300 covers the side surface of the whole formed by the support base 110 and the contact element carrier 200, at least part of the back surface of the support base 110, and at least part of the front surface of the contact element carrier 200. During brushing, the surface covering 300 can block between the support base 110 and the contact element carrier 200 and the oral inner wall and teeth, thereby playing a buffering role between the support base 110 and the contact element carrier 200 and the oral inner wall and teeth, avoiding the direct collision of the support base 110 and the contact element carrier 200 with the teeth and the occurrence of the "tooth hitting" phenomenon, improving the comfort of the user's oral cavity and the oral care element 1000, and further improving the user experience. Moreover, the surface covering 300 in the present application covers more surfaces of the support base 110 and the contact element carrier 200, and its blocking area is more comprehensive, with better use comfort.

[0050] In practical applications, the surface covering 300 can be coated on the support base 110 and the contact element carrier 200 by means of two-color injection molding or secondary insert molding, and the support base 110 and the contact element carrier 200 are bonded together. For example, the brush handle 100 is formed in the first injection molding process, and then the contact element carrier 200 is loaded into the mold for the second injection molding. The surface covering 300 is formed in the second injection molding process, and the surface covering 300 coats and connects the support base 110 and the contact element carrier 200. Of course, the surface covering 300 can also be formed by overmolding. For example, the support base 110 and the contact element carrier 200 are separately molded and then spliced together, and then the whole formed after splicing is overmolded to form the surface covering 300. Among them, the surface covering 300 can be made of a type of polymer material with a soft texture and elasticity, so as to have soft characteristics. This material can be a natural material or a synthetic material, such as silica gel, rubber, polyurethane elastomer, etc.

[0051] It should be noted that the front side of the contact element carrier 200 defined in this application refers to the side through which the free ends of the brush filaments 400 pass and extend in the contact element carrier 200 (such as Figure 2 the upper surface of the contact element carrier 200 in the perspective view). Correspondingly, the side opposite to the front side of the contact element carrier 200 is the back side of the contact element carrier 200, the side facing the back side of the contact element carrier 200 is the front side of the support base 110, the side opposite to the front side of the support base 110 is the back side of the support base 110, and the surface connecting the front side and the back side of the corresponding component is the side surface of the component.

[0052] As Figure 3 shown, in one implemented embodiment, the above-mentioned support base 110 can also block several hair-implanting through holes 240 from communicating with the external environment through the back side of the contact element carrier 200. In this way, during the molding process of the surface covering 300, that is, when pouring the liquid for forming the surface covering 300, it is possible to prevent the liquid from overflowing through the hair-implanting through holes 240 to the front side of the contact element carrier 200, resulting in product quality problems.

[0053] Regarding the cooperation mode between the contact element carrier 200 and the support base 110, the following two embodiments are provided in this application for reference.

[0054] Embodiment 1: As Figure 6As shown in the figure, an installation groove 210 is provided on the back surface of the contact element carrier 200. The support base 110 is inserted into the installation groove 210, and the back surface of the support base 110 is substantially flush with the back surface of the contact element carrier 200. At this time, the side surface of the contact element carrier 200 forms the side surface of the whole formed by the support base 110 and the contact element carrier 200. The front surface of the support base 110 is in contact with the bottom of the installation groove 210, and the support base 110 blocks and seals the opening of the hair-implanting through hole 240 on the back surface, so as to realize that the support base 110 blocks the connection between the plurality of hair-implanting through holes 240 and the external environment through the back surface of the contact element carrier 200.

[0055] Embodiment 2: As Figure 3 shown in the figure, the back surface of the contact element carrier 200 is substantially flush with the front surface of the support base 110. The side surface of the contact element carrier 200 and the side surface of the support base 110 together form the side surface of the whole formed by the support base 110 and the contact element carrier 200. The front surface of the support base 110 is in contact with the back surface of the contact element carrier 200, so as to realize that the support base 110 blocks the connection between the plurality of hair-implanting through holes 240 and the external environment through the back surface of the contact element carrier 200. In this way, during the forming process of the surface covering 300, or rather, when pouring the liquid for forming the surface covering 300, it is possible to prevent the liquid from entering between the front surface of the support base 110 and the back surface of the contact element carrier 200, that is to say, there is no surface covering element 300 between the front surface of the support base 110 and the back surface of the contact element carrier 200.

[0056] Considering that in Embodiment 2, the contact area between the surface covering 300 and the contact element carrier 200 and the support base 110 is relatively uniform and large, and the reliability of connecting the contact element carrier 200 and the support base 110 by using the surface covering 300 is better. Therefore, the cooperation mode between the contact element carrier 200 and the support base 110 in Embodiment 2 is preferably adopted in this application, and the following description will also be based on this.

[0057] As Figure 7As shown, in an achievable implementation, an attachment groove 220 extending inward from the side of the contact element carrier 200 is provided on the front surface of the contact element carrier 200. Correspondingly, a boss portion 260 is formed on the front surface of the contact element carrier 200. At this time, the front surface of the contact element carrier 200 is jointly constituted by the bottom of the attachment groove 220 and the front surface of the boss portion 260. Among them, the surface covering 300 is filled in the attachment groove 220 to cover a part of the front surface of the contact element carrier 200. In this way, the bonding area between the surface covering 300 and the contact element carrier 200 can be increased, ensuring the reliability of the connection between the surface covering 300 and the contact element carrier 200. In practical applications, when the surface covering 300 is filled in the attachment groove 220, the surface covering 300 can be substantially flush with the front surface of the contact element carrier 200, or the surface covering 300 is slightly lower than the front surface of the contact element carrier 200, thereby ensuring the aesthetics and also avoiding the surface covering 300 overflowing into the hair-implanting through holes 240 and affecting the normal movement of the brush filament cluster 400.

[0058] The hair-implanting through holes 240 can be formed on the boss portion 260 so that the hair-implanting through holes 240 have sufficient depth to provide better support for the brush filament cluster 400 and ensure that the brush filament cluster 400 can maintain an upright state after being inserted into the hair-implanting through holes 240.

[0059] Regarding the specific structure of the attachment groove 220, the following provides three achievable embodiments in this application for reference.

[0060] Embodiment 1: As Figure 8 shown, the attachment groove 220 may include a continuous annular groove 221 extending along the edge of the contact element carrier 200. That is to say, the annular groove 221 is provided on the edge of the contact element carrier 200 and surrounds the edge of the contact element carrier 200. In this way, it can be ensured that the surface covering 300 covered in the annular groove 221 is subjected to relatively uniform force on the contact element carrier 200, reducing the possibility of the single end of the contact element carrier 200 tilting up and separating from the surface covering 300, and improving the connection stability and reliability of the surface covering 300 to the contact element carrier 200.

[0061] Embodiment 2: As Figure 7 shown, on the basis of Embodiment 1, the attachment groove 220 may further include several inner extension grooves 222, and the inner extension grooves 222 extend inward from the side wall surface of the annular groove 221, thereby further increasing the bonding area between the surface covering 300 and the contact element carrier 200 and improving the connection stability and reliability of the surface covering 300 to the contact element carrier 200.

[0062] Furthermore, there are at least four inner extension grooves 222, and the relative two sides of the side wall surface of the annular groove 221 along the main extension line direction (i.e., Figure 7On the front and back sides from a perspective), inner extension grooves 222 are respectively provided, and at opposite ends of the side wall surface of the annular groove (221) along the main extension line (i.e., Figure 7 On the left and right ends from a perspective), inner extension grooves 222 are respectively provided, so as to ensure that the surface covering member 300 covered in the inner extension grooves 222 exerts relatively uniform force on the contact element carrier 200.

[0063] Embodiment 3: As Figure 9 shown, the attachment groove 220 may only include a plurality of inner extension grooves 222, and the plurality of inner extension grooves 222 are arranged at intervals along the edge of the contact element carrier 200.

[0064] In an implementable embodiment, the back surface of the contact element carrier 200 may be configured as a planar structure. The front surface of the support base 110 is attached to the back surface of the contact element carrier 200, and the orthographic projections of the hair implanting through holes 240 on the support base 110 are all located on the support base 110. In this way, the support base 110 is equivalent to blocking and sealing the openings of the hair implanting through holes 240 on the back surface of the contact element carrier 200, so as to achieve the above-mentioned support base 110 blocking a plurality of hair implanting through holes 240 from communicating with the external environment through the back surface of the contact element carrier 200.

[0065] Considering that during the hair implanting process, the fixed ends of the brush filament clusters 400 need to be formed into connecting pieces by hot melting and fixed on the back surface of the contact element carrier 200, which results in corresponding protrusions on the back surface of the contact element carrier 200, making it difficult for the front surface of the support base 110 to effectively fit with the back surface of the contact element carrier 200. Therefore, as Figure 3 and Figure 10 shown, in another alternative embodiment, the back surface of the contact element carrier 200 is provided with inner concave cavities communicating with a plurality of hair implanting through holes 240, and the side walls of the inner concave cavities form continuous surrounding edges 230 extending along the edge of the contact element carrier 200. In this way, a plurality of hair implanting through holes 240 are located within the area formed by the surrounding edges 230, and the inner concave cavities can reserve space for the connecting pieces formed by hot melting the fixed ends of the brush filament clusters 400, so as to avoid the connecting pieces protruding from the back surface of the contact element carrier 200. Furthermore, the front surface of the support base 110 can be effectively attached to the back surface of the contact element carrier 200, or rather, the front surface of the support base 110 can be effectively attached to the back surface of the surrounding edge 230, so as to achieve the above-mentioned support base 110 blocking a plurality of hair implanting through holes 240 from communicating with the external environment through the back surface of the contact element carrier 200.

[0066] Moreover, the liquid formed during the hot melting of the fixed ends of the brush filament clusters 400 is restricted by the surrounding edges 230, which can avoid the liquid formed during the hot melting from overflowing to the outside of the contact element carrier 200 and causing defects, facilitating the control of production quality.

[0067] In practical applications, the surrounding edge 230 can be connected to the contact element carrier 200 by means of ultrasonic welding, bonding or the like. Preferably, the surrounding edge 230 can be integrally injection-molded with the contact element carrier 200, thereby simplifying the production process and reducing the production cost.

[0068] As Figure 5 and Figure 10 shown, in an implementable embodiment, the contact element carrier 200 is provided with an anti-fooling member 250 that extends beyond the back surface of the contact element carrier 200, and the front surface of the support base 110 is provided with a mating groove 111 that is adapted to the anti-fooling member 250. In this way, when the contact element carrier 200 abuts against the front surface of the support base 110 in a direction perpendicular to the main extension line, the anti-fooling member 250 can be inserted into the mating groove 111, thereby preventing the contact element carrier 200 from being reversely installed. In practical applications, the anti-fooling member 250 can be disposed near the surrounding edge 230, such that the anti-fooling member 250 is adjacent to the edge of the contact element carrier 200, so that the user can refer to the anti-fooling member 250 being inserted into the mating groove 111 for convenient insertion operation.

[0069] In another alternative embodiment, the back surface of the surrounding edge 230 can be provided with a mating groove 111, and the front surface of the support base 110 can be provided with an anti-fooling member 250 that is adapted to the mating groove 111, which can also achieve the function of preventing the contact element carrier 200 from being reversely installed.

[0070] Of course, during the injection molding process, the contact element carrier 200 can also utilize the limiting structure on the module to achieve the function of preventing the contact element carrier 200 from being reversely installed, and the present application does not make specific limitations thereto.

[0071] Based on the same inventive concept, as Figure 11 shown, the present application further provides an oral cleaner, which can include a holding portion 2000 and an oral care element 1000. The oral care element 1000 is mounted on the holding portion 2000 to drive the oral care element 1000 to move through a driving device on the holding portion 2000, or such that an external force drives the oral care element 1000 to move through the holding portion 2000.

[0072] It should be noted that, regarding the specific structure of the oral care element 1000, reference can be made to the content described in the above embodiments, and details are not described herein again.

[0073] In another alternative embodiment, the back surface of the contact element carrier 200 is substantially flush with the front surface of the support base 110, and the back surface of the contact element carrier 200 and the front surface of the support base 110 are formed to be substantially flush by bonding or ultrasonic welding. At this time, the contact element carrier 200 and the support base 110 do not need to pass through the surface covering member 300. The side surfaces of the support base 110 and the contact element carrier 200 may or may not be provided with the surface covering element 300, and the present application does not make specific limitations thereon.

[0074] Regarding the fixing manner of the brush filament cluster 400, in an implementable embodiment, one end of the brush filament cluster 400 passing through the back surface of the contact element carrier 200 is fixed by melting. Among them, one end of the brush filament cluster 400 passing through the back surface of the contact element carrier 200 can be melted and fixed on the back surface of the contact element carrier 200 to achieve fixation, or can be melted into a mass and then covered and limited by the surface covering member 300 entering the back surface of the contact element carrier 200 to achieve fixation, or, after being melted into a mass, it is pressed and limited by the support base 110 to achieve fixation.

[0075] In practical applications, the melted ends of multiple brush filament clusters 400 can be independent of each other, or at least partially melted together.

[0076] It can be seen from this that in the technical solution provided by the present application, the surface covering member simultaneously covers the side surfaces of the whole formed by the support base and the contact element carrier, at least part of the back surface of the support base, and at least part of the front surface of the contact element carrier, increasing the bonding area between the surface covering member and the support base and the contact element carrier, thereby increasing the bonding strength between the surface covering member and the support base and the contact element carrier, and further making the bonding strength sufficient to firmly connect the support base and the contact element carrier, without the need to pre-connect the support base and the contact element carrier and then cover the surface covering member, simplifying the production process and reducing the production cost.

[0077] At the same time, the surface covering member simultaneously covers the side surfaces of the whole formed by the support base and the contact element carrier, at least part of the back surface of the support base, and at least part of the front surface of the contact element carrier. During toothbrushing, the surface covering member can block between the support base and the contact element carrier and the inner wall of the oral cavity and the teeth, thereby playing a buffering role between the support base and the contact element carrier and the inner wall of the oral cavity and the teeth, avoiding the direct collision of the support base and the contact element carrier with the teeth and the occurrence of the phenomenon of "hitting the teeth", improving the comfort of the user's oral cavity and the oral care element, and further improving the user experience. Moreover, the surface covering member of the present application covers more surfaces of the support base and the contact element carrier, and its blocking area is more comprehensive, and the use comfort is better.

[0078] Moreover, the support base can also prevent a plurality of hair-implanting through holes from communicating with the external environment through the back surface of the contact element carrier. In this way, during the forming process of the surface covering, or rather, when pouring the liquid for forming the surface covering, it is possible to avoid the liquid overflowing to the front surface of the contact element carrier through the hair-implanting through holes, which may cause product quality problems.

[0079] Furthermore, a concave cavity communicating with the plurality of hair-implanting through holes is provided on the back surface of the contact element carrier, and the side wall of the concave cavity forms a continuous border extending along the edge of the contact element carrier. In this way, the plurality of hair-implanting through holes are located within the area formed by the border, and the concave cavity can reserve space for the connecting piece formed by the heat melting of the fixed end of the brush filament cluster, so as to prevent the connecting piece from protruding from the back surface of the contact element carrier. Furthermore, the front surface of the support base can be effectively attached to the back surface of the contact element carrier, or rather, the front surface of the support base can be effectively attached to the back surface of the border, so as to achieve the above-mentioned function that the support base prevents the plurality of hair-implanting through holes from communicating with the external environment through the back surface of the contact element carrier. Moreover, the liquid formed during the heat melting of the fixed end of the brush filament cluster is restricted by the border, which can avoid the liquid formed during the heat melting from overflowing to the outside of the contact element carrier, resulting in defects, and is convenient for controlling the production quality.
