[0002] This application claims priority to Chinese Patent Application No. 2024223925561, filed on September 27, 2024, entitled “Oral care elements and oral care devices.” The entire contents of this Chinese patent application are incorporated by reference herein. TECHNICAL FIELD

[0003] The present application relates to the technical field of personal care, in particular to an oral care element and an oral care device. BACKGROUND

[0004] With the improvement of oral health awareness, the oral care device has become the first choice for many families.

[0005] The oral care element of the related oral care device can include a contact element carrier and a brush handle with a support seat, and the brush handle is connected with the contact element carrier through the support seat. The contact element carrier and the support seat are usually hard seats, and the contact element carrier and the support seat are easy to collide with the teeth during high-speed vibration during tooth brushing, thereby causing the “hit tooth” phenomenon, which affects the user experience.

DETAILED DESCRIPTION

[0034] In the related art, the oral care element of the all-in-one machine is usually composed of a contact element carrier and a support seat, the contact element carrier fixes the bristle tuft and is connected with the handle through the support seat. Since the all-in-one machine integrates the functions of brushing and rinsing, in order to form a fixed fluid channel in the contact element carrier and the support seat to provide stable fluid output to realize the rinsing function, the contact element carrier and the support seat are usually made of hard material. Moreover, the contact element carrier and the support seat made of hard material can also ensure that the high-frequency vibration from the built-in motor can be effectively transmitted to the bristle tuft, and ensure the stability and durability of the structure.

[0035] However, the use of such hard materials also brings certain problems. When using the oral care device to brush teeth, the contact element carrier and the support base can collide with the teeth due to the high-speed vibration of the oral care elements. Such collision is referred to as the "hit teeth" phenomenon, which not only can cause unnecessary pressure on the teeth, but also can affect the user's experience, and even cause gum discomfort or tooth sensitivity.

[0036] To this end, the present application wraps the outer surface of the support base and the contact element carrier with soft glue to form a soft protective layer, thereby reducing the direct collision between the hard materials such as the support base and the contact element carrier and the oral organs such as the teeth, to improve the user's comfort and experience. At the same time, it is ensured that the soft protective layer does not penetrate between the contact surfaces of the contact element carrier and the support base, so that when the liquid for forming the surface soft glue is poured, the liquid can be prevented from overflowing through the hair implantation through hole to the front surface of the contact element carrier, and the liquid can be prevented from penetrating into the fluid channel inside the contact element carrier and the support base to cause product defects. In this way, the brushing comfort is improved while the product yield is improved.

[0037] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments.

[0038] The present application provides an oral care element 1000 which can be detachably or fixedly connected to the brush handle assembly 2000 of the oral care device (or the oral care device). Taking the example of the detachable connection of the oral care element 1000 to the brush handle assembly 2000 of the oral care device, the user can hold the brush handle assembly 2000 to drive the oral care element 1000 to perform cleaning operation, the brush handle assembly 2000 can drive the oral care element 1000 to vibrate and deliver impact water flow to the oral care element 1000, and simultaneously or sequentially realize the functions of tooth brushing and water flow flushing to improve the cleaning effect. When the oral care element 1000 is damaged, the oral care element 1000 can also be conveniently replaced to reduce the replacement cost.

[0039] Specifically, please refer to the figures 1 to 3, in an implementable embodiment, the oral care element 1000 can include a brush handle 100, a contact element carrier 200 and a surface covering element 300. Among them, the brush handle 100 extends along the main extension line direction, the brush handle 100 defines a fluid guide channel 110 for fluid to pass through, and a first inlet 111 and a first outlet 112 in communication with the fluid guide channel 110, the first inlet 111 and the first outlet 112 are located at opposite ends (such as the left end and the right end shown in Figure 3) of the brush handle 100 on the main extension line, the fluid can flow into the fluid guide channel 110 through the first inlet 111, and flow out of the first outlet 112 under the guidance of the fluid guide channel 110. It should be pointed out that the main extension line defined in the present application refers to a straight line composed of the main extension direction of the overall structure of the brush handle 100 (as shown in Figure 2), for example, when the brush handle 100 is approximately cylindrical, the main extension line of the brush handle 100 is the axis of the brush handle 100.

[0040] In the present embodiment, the contact element carrier 200 is mounted on one end of the brush handle 100 adjacent to the first outlet 112 along the direction intersecting the main extension line, and the contact element carrier 200 at least partially protrudes from the brush handle 100. Correspondingly, the contact element carrier 200 is provided with brush tufts 400 extending along the direction intersecting the main extension line and a water jet portion 210 in communication with the first outlet 112, so that when the brush handle 100 is inserted into the oral cavity during oral cleaning, the brush tufts 400 and the water jet portion 210 are directed towards the teeth and / or part of the inner wall of the oral cavity, so that the brush tufts 400 can brush and rinse the teeth and / or part of the inner wall of the oral cavity, to facilitate the user's oral cleaning operation.

[0041] In the present embodiment, the surface covering element 300 has a soft property, the surface covering element 300 covers the side surface of the overall structure formed by the one end of the brush handle 100 adjacent to the first outlet 112 and the contact element carrier 200, and connects the contact element carrier 200 and the brush handle 100. In this way, during brushing, the surface covering element 300 can block the brush handle 100 and the contact element carrier 200 from directly colliding with the inner wall of the oral cavity and the teeth, thereby buffering the brush handle 100 and the contact element carrier 200 from directly colliding with the inner wall of the oral cavity and the teeth, avoiding the "hit teeth" phenomenon, improving the comfort of the user's oral cavity and the oral care element 1000, and further improving the user's experience.

[0042] In practical applications, the surface covering element 300 can be covered on the side of the brush handle 100 adjacent to the first outlet 112 and the contact element carrier 200 in a way of secondary injection molding or secondary over-molding. For example, the brush handle 100 is formed in a first injection molding process, and then the contact element carrier 200 is installed in a mold for a second injection molding process, and the surface covering element 300 is formed in the second injection molding process. Of course, the surface covering element 300 can also be formed by over-molding. For example, the brush handle 100 and the contact element carrier 200 are separately formed and then spliced together, and then the spliced whole is over-molded to form the surface covering element 300. The surface covering element 300 can be made of a kind of high polymer material with soft texture and elasticity, thereby having soft characteristics. The material can be a natural material or a synthetic material, such as silicone, rubber, polyurethane elastomer, etc.

[0043] The brush handle 100 and the contact element carrier 200 can be connected together by the covering and bonding action of the surface covering element 300. The brush handle 100 and the contact element carrier 200 can also be connected together by the combined action of the covering and bonding of the surface covering element 300 and ultrasonic welding, so as to further improve the reliability and stability of the connection between the brush handle 100 and the contact element carrier 200.

[0044] Regarding the fixing mode of the brush filament cluster 400, in one implementable embodiment, the brush filament cluster 400 can be fixed on the contact element carrier 200 by coppering.

[0045] In another optional embodiment, the brush filament cluster 400 can also be fixed on the contact element carrier 200 by non-coppering. Specifically, the contact element carrier 200 is provided with a plurality of planting hole through holes for installing the brush filament cluster 400, the planting hole through holes penetrating through opposite surfaces of the contact element carrier 200, and the planting hole through holes limiting the brush filament cluster 400 in the through hole radial direction. The end of the brush filament cluster 400 penetrating through the back surface of the contact element carrier 200 can be fused to the back surface of the contact element carrier 200 to realize fixation. The fused ends of the plurality of brush filament clusters 400 can be independent of each other or at least partially fused together. It should be noted that the surface adjacent to the free end of the brush filament cluster 400 is the front surface, and the surface adjacent to the fixed end of the brush filament cluster 400 is the back surface.

[0046] It is worth mentioning that when the brush filament cluster 400 is fixed on the contact element carrier 200 in a way of copper-free implantation, the above-mentioned surface coating element 300 is coated on the side of the brush handle 100 adjacent to one end of the first outlet 112 and the contact element carrier 200 to form an integral whole. In this way, during the molding process of the surface coating element 300, or during the liquid filling process of the surface coating element 300, the liquid can be prevented from entering the back of the contact element carrier 200, thereby avoiding the problem of product defects caused by overflow of the liquid through the implantation through hole to the front of the contact element carrier 200, and improving the yield of the product.

[0047] As shown in FIGS. 4 and 5, in an implementable embodiment, the brush handle 100 has a support seat 120 at one end along the main extension line, which is used to attach the contact element carrier 200 to provide support for the contact element carrier 200 and transmit vibration energy from the brush handle assembly 2000. Specifically, the support seat 120 is provided with a mounting groove 121 on one side (such as the upper side in FIG. 4) along the main extension line, the flow guide channel 110 extends to the support seat 120 and is at least partially located below the mounting groove 121, the first outlet 112 is formed at the groove bottom of the mounting groove 121, and the contact element carrier 200 is mounted in the mounting groove 121 in a direction perpendicular to the main extension line.

[0048] In this way, the contact element carrier 200 can be mounted on the brush handle 100 according to the shape of the mounting groove 121, thereby facilitating the mounting operation of the contact element carrier 200. At the same time, by mounting the contact element carrier 200 in the mounting groove 121, the mounting groove 121 can also cooperate with the contact element carrier 200 to limit the contact element carrier 200, thereby reducing the degree of freedom of the contact element carrier 200 relative to the support seat 120. Correspondingly, the surface coating element 300 only needs to limit the contact element carrier 200 in the vertical direction under the perspective of FIG. 4, thereby improving the reliability and stability of connecting the brush handle 100 and the contact element carrier 200 together only through the coating and bonding action of the surface coating element 300.

[0049] In actual application, the brush handle 100 can drive the contact element carrier 200 to vibrate through the support seat 120, so that the contact element carrier 200 can transmit the vibration received thereby to the brush filament cluster 400 to drive the brush filament cluster 400 to vibrate, so that the vibrating brush filament cluster 400 can help to better transmit the toothpaste and moisture on the brush filament cluster 400 to the tooth surface and the gum edge, thereby more thoroughly removing food residues, bacteria and dental plaque. In addition, the vibrating brush filament cluster 400 can also more easily enter the interdental space and the vicinity of the gum line, thereby improving the cleaning range.

[0050] In an implementable embodiment, the surface coating element 300 can also coat at least part of the surface of the support base 120 away from the contact element carrier 200, that is, the surface coating element 300 also coats the back surface of the support base 120, so that the surface coating element 300 coats more surfaces of the support base 120, so that the surface coating element 300 can provide more comprehensive barrier between the support base 120 and the inner wall of the oral cavity and the teeth, further avoid the direct collision between the brush handle 100 and the contact element carrier 200 and the teeth, and the phenomenon of "hitting teeth", improve the comfort of the user's oral cavity and the oral care element 1000, and further improve the user experience.

[0051] As shown in FIGS. 6-8, in an implementable embodiment, the contact element carrier 200 has a first section 220 and a second section 230 connected to each other, and the first section 220 is located between the second section 230 and the support base 120 in a direction perpendicular to the main extension line. Among them, the side surface of the first section 220 is located within the range of the side surface of the second section 230, that is, the side surface size of the second section 230 is greater than that of the first section 220, the side surface of the first section 220 is inwardly retracted from the side surface of the second section 230 by a certain distance, and the first step surface 240 is formed between the side surface of the first section 220 and the side surface of the second section 230. When the contact element carrier 200 is installed in the mounting groove 121 in a direction perpendicular to the main extension line, the first section 220 is inserted into the mounting groove 121, and the first step surface 240 is in contact with the surface of the support base 120 adjacent to the second section 230. Correspondingly, the side surface of the second section 230 and the side surface of the support base 120 together constitute the side surface of the above-mentioned whole formed by the end of the brush handle 100 adjacent to the first outlet 112 and the contact element carrier 200.

[0052] In the above manner, by the way that the first step surface 240 is in contact with the surface of the support base 120 adjacent to the second section 230, the possibility of the liquid used to form the surface coating element 300 entering between the side surface of the support base 120 and the inner wall surface of the mounting groove 121, and between the front surface of the support base 120 and the back surface of the contact element carrier 200, can be reduced, avoiding the overflow to the front surface of the contact element carrier 200 through the bristle through hole and causing product quality problems, and ensuring product yield. That is, there is no surface coating element 300 between the front surface of the support base 120 and the back surface of the contact element carrier 200, but there can be overflowed surface coating element 300 between the side surface of the first section 220 and the inner wall surface of the mounting groove 121, and there can also be no surface coating element 300 between the side surface of the first section 220 and the inner wall surface of the mounting groove 121.

[0053] Meanwhile, the first step surface 240 is in close contact with one side of the support base 120 adjacent to the second section 230, and can also transmit the pressure applied to the contact element carrier 200 to the support base 120 through the first step surface 240 during tooth brushing, so as to reduce the pressure applied to the contact element carrier 200 at the first outlet 112, and reduce the possibility of damage to the first outlet 112 due to pressure, and improve the service life of the product.

[0054] In actual application, the first section 220 is gradually inwardly convergent at least in part away from the second section 230, so that the size of the end of the first section 220 away from the second section 230 is smaller than the opening size of the mounting groove 121, so as to facilitate insertion of the first end of the contact element carrier 200 into the mounting groove 121.

[0055] Please refer to FIGS. 7 and 8 again, in an implementable embodiment, one side of the second section 230 away from the first section 220 is provided with an attachment groove 231 extending inwardly from the side surface of the second section 230. The surface covering element 300 is filled in the attachment groove 231, so that the surface covering element 300 can also partially cover one side of the contact element carrier 200 away from the support base 120, that is, the surface covering element 300 can also cover part of the front surface of the contact element carrier 200. In this way, the bonding area of the surface covering element 300 and the contact element carrier 200 can be increased, and the reliability of the connection between the surface covering element 300 and the contact element carrier 200 can be ensured.

[0056] In actual application, one side of the second section 230 away from the first section 220 is provided with an attachment groove 231 extending inwardly from the side surface of the second section 230, and the one side of the second section 230 away from the first section 220 forms a corresponding boss portion, and the hair implantation through hole can be formed on the boss portion, so that the hair implantation through hole has sufficient depth, and can 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 implantation through hole. When the surface covering element 300 is filled in the attachment groove 231, the surface covering element 300 can be substantially flush with the top surface of the boss portion, or the surface covering element 300 can be slightly lower than the top surface of the boss portion, so as to ensure the aesthetic appearance, and also avoid the surface covering element 300 overflowing into the hair implantation through hole and affecting the normal movement of the brush filament cluster 400.

[0057] Regarding the specific structure of the attachment groove 231, three implementable embodiments are provided below for reference.

[0058] In the embodiment, the attachment groove 231 can include a continuous annular groove 2311 extending along the edge of the contact element carrier 200. That is, the annular groove 2311 is arranged at the edge of the contact element carrier 200 and surrounds the edge of the contact element carrier 200. In this way, the surface covering element 300 wrapped in the annular groove 2311 can ensure that the force applied by the surface covering element 300 to the contact element carrier 200 is relatively uniform, reducing the possibility of the single end of the contact element carrier 200 being lifted and separated from the surface covering element 300, and improving the connection stability and reliability of the surface covering element 300 to the contact element carrier 200.

[0059] In the embodiment, the attachment groove 231 can include a continuous annular groove 2311 extending along the edge of the contact element carrier 200. That is, the annular groove 2311 is arranged at the edge of the contact element carrier 200 and surrounds the edge of the contact element carrier 200. In this way, the surface covering element 300 wrapped in the annular groove 2311 can ensure that the force applied by the surface covering element 300 to the contact element carrier 200 is relatively uniform, reducing the possibility of the single end of the contact element carrier 200 being lifted and separated from the surface covering element 300, and improving the connection stability and reliability of the surface covering element 300 to the contact element carrier 200.

[0060] In the embodiment, the attachment groove 231 can include a continuous annular groove 2311 extending along the edge of the contact element carrier 200. That is, the annular groove 2311 is arranged at the edge of the contact element carrier 200 and surrounds the edge of the contact element carrier 200. In this way, the surface covering element 300 wrapped in the annular groove 2311 can ensure that the force applied by the surface covering element 300 to the contact element carrier 200 is relatively uniform, reducing the possibility of the single end of the contact element carrier 200 being lifted and separated from the surface covering element 300, and improving the connection stability and reliability of the surface covering element 300 to the contact element carrier 200.

[0061] As shown in FIG. 9, in an implementable embodiment, the water spraying part 210 is protruded from the side of the contact element carrier 200 away from the support base 120, and the protrusion height of the water spraying part 210 does not exceed the brush wire cluster 400, that is, the water spraying part 210 is located below the free end of the brush wire cluster 400. In this way, the water spraying part 210 can be close enough to the teeth to make the sprayed fluid have a better cleaning effect, and the probability of the water spraying part 210 contacting the teeth can be reduced during brushing, thereby reducing the discomfort caused by the contact between the water spraying part 210 and the teeth and improving the user experience.

[0062] In actual application, the water spraying part 210 can be made of elastic material, such as rubber, silica gel, etc. In this way, on the one hand, if the water spraying part 210 contacts the teeth due to the user's excessive force during brushing, the problem of poor experience caused by the water spraying part 210 hitting the teeth can be avoided; on the other hand, the water spraying part 210 is used to be installed on the toothbrush, and the structure is exquisite, and the elastic material is easy to process, so as to avoid the problem of cracks in the processing of the axial through hole.

[0063] The above water spraying part 210 can be an integral structure with the contact element carrier 200, and the water spraying part 210 can be installed into the installation groove 121 integrally with the contact element carrier 200.

[0064] The water spraying part 210 can also be in a separate structure from the contact element carrier 200. The water spraying part 210 can be fixed on the contact element carrier 200 by plug-in, threaded connection or other connection methods, or fixed on the bottom of the mounting groove 121 and protrude from the front of the contact element carrier 200 to form a protrusion.

[0065] For the installation of the water spraying part 210 and the contact element carrier 200, the application preferably adopts an integrated structure of the water spraying part 210 and the contact element carrier 200, and the subsequent description is also based on this.

[0066] As shown in FIG. 9, in an implementable embodiment, the water spraying part 210 has a first through hole 211. The bottom of the mounting groove 121 is provided with a protrusion 130 extending towards the contact element carrier 200, and the protrusion 130 is provided with a second through hole 131 communicating with the flow guide channel 110, and the end of the second through hole 131 away from the flow guide channel 110 forms the first outlet 112. When the contact element carrier 200 is installed in the mounting groove 121 along a direction perpendicular to the main extension line, the water spraying part 210 is sleeved on the protrusion 130, or in other words, the protrusion 130 is plugged into the first through hole 211, and the flow guide channel 110 communicates with the first through hole 211 through the second through hole 131. In this way, the fluid from the flow guide channel 110 can be sprayed out of the water spraying part 210 through the second through hole 131 and the first through hole 211 in sequence.

[0067] Furthermore, it can be understood that through the above scheme, when the contact element carrier 200 is installed, the contact element carrier 200 can be positioned and installed by plugging the protrusion 130 into the first through hole 211, to ensure the accuracy of the butt joint of the water spraying part 210 and the first outlet 112.

[0068] In actual application, the first through hole 211 can be a through hole with constant aperture. The first through hole 211 can also be a through hole with variable aperture. Specifically, the first through hole 211 can include a first hole section and a second hole section in communication, the aperture of the first hole section is smaller than that of the second hole section, and the second hole section is adjacent to and communicates with the first outlet 112. In this way, after the fluid flows out of the first outlet 112, it can be sprayed out of the second hole section and the first hole section in sequence. Since the inner diameter of the first hole section is smaller than that of the second hole section, when the flow rate is constant, the flow rate of the fluid in the first hole section is greater than that in the second hole section, thereby increasing the spraying speed of the fluid and the cleaning effect of the fluid on the teeth. Of course, the aperture of the first through hole 211 can also gradually decrease away from the first outlet 112, which can also achieve the purpose of increasing the spraying speed of the fluid and the cleaning effect of the fluid on the teeth.

[0069] To ensure the sealing of the communication between the first through hole 211 and the second through hole 131, in an implementable embodiment, the outer wall surface of the convex part 130 and the inner wall surface of the first through hole 211 are provided with a sealing member 500, and the gap between the outer wall surface of the convex part 130 and the inner wall surface of the first through hole 211 is sealed by the sealing member 500.

[0070] In actual application, the sealing member 500 can be a sealing ring, which can be first sleeved on the convex part 130, and when the contact element carrier 200 is installed into the mounting groove 121, the sealing ring is extruded between the convex part 130 and the inner wall surface of the first through hole 211.

[0071] Based on the same inventive concept, as shown in FIG. 10, the present application also provides an oral care device integrating tooth brushing and rinsing functions. Specifically, the oral care device can include a brush handle assembly 2000 and an oral care element 1000, wherein the brush handle assembly 2000 can include a holding housing 610 and a driving device 620 installed in the holding housing 610, a power output shaft 621 of the driving device 620 extends out of the holding housing 610, and the power output shaft 621 has an axial passage 622. The oral care element 1000 is connected with the power output shaft 621 and is driven by the power output shaft 621 to perform displacement movement, and a fluid outlet of the axial passage 622 is in communication with the first inlet 111, and the oral care device outputs water flow through the water spraying part 210.

[0072] In the present embodiment, the holding housing 610 can further be provided with a liquid storage chamber 630 and a fluid pumping unit 640. The fluid inlet of the axial passage 622 can be in communication with the liquid storage chamber 630, and the fluid pumping unit 640 is connected in series on the flow passage of the liquid storage chamber 630 and the fluid inlet of the axial passage 622, so that the fluid pumping unit 640 can extract the fluid in the liquid storage chamber 630 and flow out of the fluid outlet of the axial passage 622 through the axial passage 622, and then sequentially pass through the first inlet 111, the flow guide passage 110 and the first outlet 112 to be sprayed from the water spraying part 210.

[0073] In practical applications, for ease of user grip, the grip housing 610 can be shaped like a slender body, and its cross-sectional shape can be circular or non-circular (such as D-shaped, elliptical, polygonal, etc.). The brush handle 100 can have a first end and a second end disposed opposite to each other on the main extension line, with the aforementioned support base 120 located at the second end of the brush handle 100. The first end of the brush handle 100 can be provided with an upper bracket 140, a Y-ring 150, and a lower bracket 160, which are sequentially assembled into the brush handle 100 through an opening at the second end. When the oral care element 1000 is inserted into the power output shaft 621, the guide surface on the outer surface of the power output shaft 621 is aligned with the inner surface of the upper bracket 140, and the elastic buckle portion of the upper bracket 140 engages with the groove on the outer surface of the power output shaft 621, thereby fixing the oral care element 1000. At this time, the inner end face of the Y-ring 150 mates with the outer surface of the power output shaft 621, and the outer end face of the Y-ring 150 fits against the inner wall of the brush handle 100, thereby forming a seal on the first end of the brush handle 100 and preventing liquid in the guide channel 110 from overflowing from the first end of the brush handle 100. When the oral care element 1000 is subjected to a force away from the brush handle assembly 2000, this force can overcome the snap-fit ​​force of the elastic buckle, causing the power output shaft 621 of the brush handle assembly 2000 to separate from the upper bracket 140, thus facilitating the replacement of the oral care element 1000.

[0074] The specific structure of the oral care element 1000 can be found in the detailed description in the above embodiments, and will not be repeated here.
