Description

Technical Field

[0001] The present application relates to the field of personal care technology, and in particular to an oral care element and an oral care device. Background Art

[0002] With rising awareness of oral health, integrated toothbrushes have become the preferred oral care device for many families. These devices combine the brushing capabilities of an electric toothbrush with the rinsing function of an oral irrigator, effectively improving cleaning effectiveness and user experience.

[0003] The oral care element of a related oral care device may include a contact element carrier and a brush handle having a support base, which is connected to the contact element carrier via the support base. The contact element carrier and the support base are typically hard, and during brushing, the high-speed vibration of the contact element carrier and the support base can easily cause collisions with the teeth, resulting in "tooth-striking" and affecting the user experience.

[0040] In related art, the oral care element of an all-in-one toothbrush brushing machine is typically composed of a contact element carrier and a support base. The contact element carrier secures the brush filaments and is connected to the brush handle via the support base. Since the all-in-one toothbrush brushing machine integrates both brushing and rinsing functions, the contact element carrier and support base are often made of a hard material to form a fixed fluid channel inside to provide a stable fluid output for rinsing. Furthermore, the use of a hard material for the contact element carrier and support base ensures that the high-frequency vibrations from the built-in motor can be effectively transmitted to the brush filaments, ensuring the stability and durability of the structure.

[0041] However, the use of this hard material also presents certain challenges. When brushing with a toothbrush, the high-speed vibration of the oral care element can cause the contact element carrier and support base to collide with the teeth. This collision, known as "tooth banging," can not only cause unnecessary pressure on teeth but also negatively impact the user experience, potentially leading to gum discomfort or tooth sensitivity.

[0042] To this end, the present application wraps the outer surface of the support seat 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 seat and the contact element carrier and the teeth and other oral organs, so as to improve the user's comfort and experience. At the same time, it ensures that the soft protective layer does not penetrate between the contact surface of the contact element carrier and the support seat, so that when the liquid to form the surface soft glue is poured, it can be prevented from overflowing through the hair-planting holes to the front of the contact element carrier, and the liquid can be prevented from penetrating into the fluid channels inside the contact element carrier and the support seat to cause product defects. In this way, while improving the comfort of brushing teeth, the product yield is also improved.

[0043] In order to make the purpose, 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 in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments.

[0044] The present application provides an oral care element 1000 that can be detachably or fixedly connected to a handle assembly 2000 of an oral care device (or, an all-in-one irrigator). For example, in the case where the oral care element 1000 is detachably connected to the handle assembly 2000 of the all-in-one irrigator, a user can hold the handle assembly 2000 to drive the oral care element 1000 for cleaning. The handle assembly 2000 can vibrate the oral care element 1000 and deliver a water flow to the oral care element 1000, thereby simultaneously or sequentially achieving brushing and rinsing functions to enhance cleaning effectiveness. If the oral care element 1000 is damaged, it can also be easily replaced, reducing replacement costs.

[0045] For details, please refer to Figures 1 to 3 As shown, in an achievable embodiment, the oral care element 1000 may include a brush handle 100, a contact element carrier 200, and a surface covering element 300. The brush handle 100 extends along the main extension line, and defines a guide channel 110 for fluid to pass through, and a first inlet 111 and a first outlet 112 connected to the guide channel 110. The first inlet 111 and the first outlet 112 are located at opposite ends of the brush handle 100 on the main extension line (as shown in FIG. Figure 3 The fluid can flow into the guide channel 110 through the first inlet 111 and flow out from the first outlet 112 under the guidance of the guide channel 110. It should be noted that the main extension line defined in this application refers to the straight line formed by the main extension direction of the overall structure of the brush handle 100 (such as 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.

[0046] In this embodiment, the contact element carrier 200 is installed 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. Accordingly, the contact element carrier 200 is provided with a brush filament cluster 400 extending along the direction intersecting the main extension line and a water spray portion 210 connected to the first outlet 112. In this way, when cleaning the mouth, as the brush handle 100 is extended into the mouth, the brush filament cluster 400 and the water spray portion 210 are facing the teeth and / or part of the inner wall of the mouth, so that the brush filament cluster 400 can brush and rinse the teeth and / or part of the inner wall of the mouth, so as to facilitate the user's oral cleaning operation.

[0047] In this embodiment, the surface covering element 300 has a soft property. The surface covering element 300 covers the side surface formed by the 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 to the brush handle 100. In this way, when brushing teeth, the surface covering element 300 can block the inner wall of the oral cavity and teeth from the brush handle 100 and the contact element carrier 200, thereby providing a buffering effect between the brush handle 100 and the contact element carrier 200 and the inner wall of the oral cavity and teeth, preventing the brush handle 100 and the contact element carrier 200 from directly colliding with the teeth and causing "tooth-knocking" phenomenon, thereby improving the comfort between the user's oral cavity and the oral care element 1000, and thus enhancing the user experience.

[0048] In practical applications, the surface coating element 300 can be coated on the side of the whole formed by the end of the brush handle 100 adjacent to the first outlet 112 and the contact element carrier 200 by means of secondary injection molding or secondary lamination. 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 a second injection molding, and the surface coating element 300 is formed in the second injection molding process. Of course, the surface coating element 300 can also be formed by rubber coating. For example, the brush handle 100 and the contact element carrier 200 are separately molded and spliced ​​together, and then the whole formed after splicing is rubber coated to form the surface coating element 300. Among them, the surface coating element 300 can be made of a type of polymer material with a soft texture and elasticity, so as to have soft properties. The material can be a natural material or a synthetic material, such as silicone, rubber, polyurethane elastomer, etc.

[0049] The brush handle 100 and the contact element carrier 200 can be connected together solely through the coating and bonding of the surface coating element 300. Alternatively, the brush handle 100 and the contact element carrier 200 can be connected together through the combined coating and bonding of the surface coating element 300 and ultrasonic welding to further improve the reliability and stability of the connection between the brush handle 100 and the contact element carrier 200.

[0050] Regarding the fixing method of the brush filament cluster 400, in one feasible embodiment, the brush filament cluster 400 can be fixed on the contact element carrier 200 by copper implantation.

[0051] In another optional embodiment, the brush filament cluster 400 can also be fixed to the contact element carrier 200 by means of copper-free hair planting. Specifically, the contact element carrier 200 is provided with a plurality of hair planting through holes for installing the brush filament cluster 400, and the hair planting through holes pass through two opposite sides of the contact element carrier 200, and the hair planting through holes limit the brush filament cluster 400 in the radial direction of the through hole. One end of the brush filament cluster 400 passing through the back side of the contact element carrier 200 can be sintered to the back side of the contact element carrier 200 to achieve fixation. Among them, the sintered ends of the multiple brush filament clusters 400 can be independent of each other, or can be at least partially fused together. It should be pointed out that the side of the contact element carrier 200 adjacent to the free end of the brush filament cluster 400 is the front side, and the side adjacent to the fixed end of the brush filament cluster 400 is the back side.

[0052] It is worth mentioning that when the brush filament cluster 400 is fixed on the contact element carrier 200 by means of copper-free hair planting, the above-mentioned surface coating element 300 is coated on the side surface formed by the end of the brush handle 100 adjacent to the first outlet 112 and the contact element carrier 200. This can also prevent the liquid from entering the back side of the contact element carrier 200 during the molding process of the surface coating element 300, or in other words, during the process of pouring the liquid to form the surface coating element 300, thereby preventing the liquid from overflowing through the hair planting hole to the front side of the contact element carrier 200 and causing product defects, thereby improving the product yield.

[0053] like Figure 4 and Figure 5 As shown, in an achievable embodiment, the brush handle 100 has a support base 120 at one end along the main extension line. The support base 120 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 brush handle assembly 2000. Specifically, the support base 120 is provided along one side of the main extension line (such as Figure 4 A mounting groove 121 is provided (on the upper side), the 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 bottom of the mounting groove 121, and the contact element carrier 200 is installed in the mounting groove 121 along a direction perpendicular to the main extension line.

[0054] In the above manner, the contact element carrier 200 can be installed on the brush handle 100 with reference to the shape of the mounting groove 121, thereby facilitating the installation of the contact element carrier 200. At the same time, by installing the contact element carrier 200 into the mounting groove 121, the mounting groove 121 can also cooperate with the contact element carrier 200 to restrict the contact element carrier 200, thereby reducing the freedom of movement of the contact element carrier 200 relative to the support base 120. Accordingly, the surface covering element 300 only needs to be Figure 4The contact element carrier 200 is limited in the vertical direction under the viewing angle, thereby improving the reliability and stability of connecting the brush handle 100 and the contact element carrier 200 only through the covering and bonding effect of the surface covering element 300.

[0055] In actual use, the brush handle 100 can drive the contact element carrier 200 to vibrate through the support base 120. In this way, the contact element carrier 200 can transmit the vibrations it receives to the brush filament cluster 400, thereby driving the brush filament cluster 400 to vibrate. The vibrating brush filament cluster 400 can help better transfer the toothpaste and water on the brush filament cluster 400 to the tooth surface and gum margin, thereby more thoroughly removing food residue, bacteria and dental plaque. In addition, the vibrating brush filament cluster 400 can more easily enter the gaps between teeth and near the gum line, thereby improving the cleaning range.

[0056] In a feasible embodiment, the surface covering element 300 can also cover at least a portion of the side of the support seat 120 away from the contact element carrier 200, that is, the surface covering element 300 also covers the back side of the support seat 120, so that the surface covering element 300 covers more surfaces of the support seat 120, so that the surface covering element 300 can provide a more comprehensive barrier between the support seat 120 and the inner wall of the oral cavity and the teeth, further avoiding the brush handle 100 and the contact element carrier 200 from directly hitting the teeth, causing the "tooth knocking" phenomenon, improving the comfort of the user's oral cavity and the oral care element 1000, and thereby improving the user's usage experience.

[0057] like Figures 6 to 8 As shown, in one practicable embodiment, the contact element carrier 200 comprises a first section 220 and a second section 230 connected to each other. Along a direction perpendicular to the main extension line, the first section 220 is located between the second section 230 and the support base 120. The side surface of the first section 220 is located within the side surface of the second section 230. In other words, the side surface dimensions of the second section 230 are larger than those of the first section 220. The side surface of the first section 220 is retracted inwardly from the side surface of the second section 230 by a certain distance, forming a first step surface 240 between the side surfaces of the first section 220 and the second section 230. When the contact element carrier 200 is installed in the mounting slot 121 along a direction perpendicular to the main extension line, the first section 220 is inserted into the mounting slot 121, and the first step surface 240 aligns with a surface of the support base 120 adjacent to the second section 230. Accordingly, the side surface of the second section 230 and the side surface of the support base 120 together constitute the side surface of the integral body formed by the end of the brush handle 100 adjacent to the first outlet 112 and the contact element carrier 200 .

[0058] In the above manner, the first step surface 240 can be bonded to the side of the support base 120 adjacent to the second section 230, thereby reducing the possibility of liquid used to form the surface coating element 300 entering between the side of the support base 120 and the inner wall of the mounting groove 121, and between the front of the support base 120 and the back of the contact element carrier 200, thereby avoiding overflow through the hair implantation holes to the front of the contact element carrier 200 and causing product defects, thereby ensuring product yield. In other words, there is no surface coating element 300 between the front of the support base 120 and the back of the contact element carrier 200, but there may be a surface coating element 300 that overflows between the side of the first section 220 and the inner wall of the mounting groove 121, and there may also be no surface coating element 300 between the side of the first section 220 and the inner wall of the mounting groove 121.

[0059] At the same time, the first step surface 240 is in contact with a side of the support seat 120 adjacent to the second section 230, and when brushing teeth, the pressure on the contact element carrier 200 can be transmitted to the support seat 120 through the first step surface 240, thereby reducing the pressure of the contact element carrier 200 on the first outlet 112, reducing the possibility of pressure damage to the first outlet 112, and improving the service life of the product.

[0060] In actual application, at least a portion of the first section 220 gradually converges inward 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 the first end of the contact element carrier 200 to be inserted into the mounting groove 121.

[0061] Please see again Figure 7 and Figure 8 As shown, in one feasible embodiment, the side of the second section 230 facing away from the first section 220 is provided with an attachment groove 231 extending inward 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 the side of the contact element carrier 200 facing away from the support base 120. In other words, the surface covering element 300 can also cover a portion of the front surface of the contact element carrier 200. This can increase the bonding area between the surface covering element 300 and the contact element carrier 200, ensuring the reliability of the connection between the surface covering element 300 and the contact element carrier 200.

[0062] In actual application, the side of the second section 230 away from the first section 220 is provided with an attachment groove 231 extending inward from the side of the second section 230, and the side of the second section 230 away from the first section 220 forms a corresponding boss portion. The hair planting hole can be formed on the boss portion so that the hair planting hole has a sufficient depth to provide better support for the brush filament cluster 400, ensuring that the brush filament cluster 400 can remain upright after being inserted into the hair planting hole. When the surface coating element 300 is filled in the attachment groove 231, the surface coating element 300 can be roughly flush with the top surface of the raised portion, or the surface coating element 300 can be slightly lower than the top surface of the raised portion, thereby ensuring aesthetics and preventing the surface coating element 300 from overflowing into the hair planting hole and affecting the normal movement of the brush filament cluster 400.

[0063] Regarding the specific structure of the attachment groove 231 , this application provides three feasible embodiments for reference below.

[0064] Embodiment 1: The attachment groove 231 may include a continuous annular groove 2311 extending along the edge of the contact element carrier 200. In other words, the annular groove 2311 is provided at and surrounds the edge of the contact element carrier 200. This ensures that the surface coating element 300 enclosed within the annular groove 2311 is subjected to relatively uniform force on the contact element carrier 200, reducing the possibility of one end of the contact element carrier 200 tilting and separating from the surface coating element 300, thereby improving the stability and reliability of the connection between the surface coating element 300 and the contact element carrier 200.

[0065] Embodiment 2: Based on embodiment 1, the attachment groove 231 may further include a plurality of inner extension grooves 2312, which extend inward from the side wall surface of the annular groove 2311, thereby further increasing the bonding area between the surface coating element 300 and the contact element carrier 200, and improving the connection stability and reliability of the surface coating element 300 to the contact element carrier 200.

[0066] Embodiment 3: The attachment groove 231 may only include a plurality of inner extension grooves 2312 , and the plurality of inner extension grooves 2312 are arranged at intervals along the edge of the contact element carrier 200 .

[0067] like Figure 9As shown, in one feasible embodiment, the water spray portion 210 is raised relative to the contact element carrier 200 toward the side away from the support base 120, and the raised height of the water spray portion 210 does not exceed the brush filament cluster 400. In other words, the water spray portion 210 is located below the free end of the brush filament cluster 400. In this way, the water spray portion 210 can be brought close enough to the teeth to ensure that the sprayed fluid has a better cleaning effect. In addition, the probability of the water spray portion 210 contacting the teeth during brushing can be reduced, thereby reducing the discomfort caused by the contact and friction between the water spray portion 210 and the teeth, thereby improving the user experience.

[0068] In practical applications, the water spray portion 210 can be made of an elastic material, such as rubber or silicone. This can prevent the water spray portion 210 from hitting the teeth, which could result in a poor brushing experience, if the user applies too much force while brushing. Furthermore, the water spray portion 210 is designed to be mounted on the toothbrush and has a compact structure. The elastic material used facilitates machining, thus preventing cracks from forming when machining the axial through hole.

[0069] The water spray portion 210 may be an integral structure with the contact element carrier 200 , and the water spray portion 210 may be integrally installed in the installation groove 121 along with the contact element carrier 200 .

[0070] The above-mentioned water spray part 210 can also be a separate structure from the contact element carrier 200. The water spray part 210 can also be fixed to the contact element carrier 200 by plugging, threading or other connection methods, or fixed to the bottom of the mounting groove 121 and extend from the front of the contact element carrier 200 to form a protrusion.

[0071] In order to install the water spray part 210 and the contact element carrier 200, the present application preferably adopts an integrated structure of the water spray part 210 and the contact element carrier 200, and the subsequent description will be made accordingly.

[0072] like Figure 9 As shown, in one feasible embodiment, the water spray portion 210 has a first through-hole 211. A protrusion 130 extending toward the contact element carrier 200 is provided at the bottom of the mounting groove 121. The protrusion 130 is provided with a second through-hole 131 communicating with the flow channel 110. The end of the second through-hole 131, distal from the flow channel 110, forms the aforementioned first outlet 112. When the contact element carrier 200 is installed in the mounting groove 121 perpendicular to the main extension line, the water spray portion 210 is sleeved over the protrusion 130. In other words, the protrusion 130 is inserted into the first through-hole 211, and the flow channel 110 communicates with the first through-hole 211 via the second through-hole 131. In this way, fluid from the flow channel 110 can be sequentially ejected from the water spray portion 210 through the second through-hole 131 and the first through-hole 211.

[0073] Furthermore, it is understandable that, through the above solution, when installing the contact element carrier 200 , the contact element carrier 200 can be positioned and installed by inserting the protrusion 130 into the first through hole 211 to ensure the accuracy of the docking between the water spray part 210 and the first outlet 112 .

[0074] In practical applications, the first through hole 211 can be a through hole with a constant aperture. The first through hole 211 can also be a through hole with a variable aperture. Specifically, the first through hole 211 can include a first hole segment and a second hole segment that are connected, the aperture of the first hole segment is smaller than the aperture of the second hole segment, and the second hole segment is adjacent to the first outlet 112 and connected to the first outlet 112. In this way, after the fluid flows out through the first outlet 112, it can be ejected through the second hole segment and the first hole segment in sequence. Since the inner diameter of the first hole segment is smaller than the inner diameter of the second hole segment, when the flow rate is constant, the flow rate of the fluid in the first hole segment is greater than the flow rate in the second hole segment, thereby increasing the ejection speed of the fluid and increasing the cleaning effect of the fluid on the teeth. Of course, the aperture of the first through hole 211 can also gradually decrease in the direction away from the first outlet 112, which can also achieve an increase in the ejection speed of the fluid and increase the cleaning effect of the fluid on the teeth.

[0075] In order to ensure the sealing of the connection between the first through hole 211 and the second through hole 131, in a feasible embodiment, a seal 500 is provided between the outer wall surface of the protrusion 130 and the inner wall surface of the first through hole 211, and the seal 500 seals the gap between the outer wall surface of the protrusion 130 and the inner wall surface of the first through hole 211.

[0076] In practical applications, the sealing member 500 may be a sealing ring, which may be first sleeved on the protrusion 130 , and when the contact element carrier 200 is installed in the installation groove 121 , the sealing ring is squeezed between the protrusion 130 and the inner wall surface of the first through hole 211 .

[0077] Based on the same inventive concept, Figure 10 As shown, the present application also provides an oral care device that integrates brushing and rinsing functions. Specifically, the oral care device may include a handle assembly 2000 and an oral care element 1000, wherein the handle assembly 2000 may include a gripping shell 610 and a driving device 620 installed in the gripping shell 610, and a power output shaft 621 of the driving device 620 extends out of the gripping shell 610, and the power output shaft 621 has an axial channel 622. The oral care element 1000 is connected to the power output shaft 621, and the power output shaft 621 drives the oral care element 1000 to perform displacement movement, and the fluid outlet of the axial channel 622 is connected to the first inlet 111, and the oral care device outputs water flow impact through the water spraying portion 210.

[0078] In this embodiment, a liquid storage chamber 630 and a fluid pumping unit 640 may also be provided in the gripping housing 610. The fluid inlet of the axial channel 622 can be in communication with the liquid storage chamber 630, and the fluid pumping unit 640 is connected in series to the flow path connecting the fluid inlet of the axial channel 622 and the liquid storage chamber 630, so that the fluid pumping unit 640 can extract the fluid in the liquid storage chamber 630 and flow the fluid out of the fluid outlet of the axial channel 622 through the axial channel 622, and then spray the fluid out of the water spraying portion 210 through the first inlet 111, the diversion channel 110, and the first outlet 112 in sequence.

[0079] In practice, to facilitate gripping by the user, the grip housing 610 may be shaped like an elongated main body, and the cross-section of the grip housing 610 may be circular or non-circular (e.g., D-shaped, oval, polygonal, etc.). The handle 100 may have a first end and a second end disposed opposite each other along a main extension line, with the support base 120 located at the second end of the handle 100. The first end of the handle 100 may be provided with an upper bracket 140, a Y-ring 150, and a lower bracket 160. The upper bracket 140, Y-ring 150, and lower bracket 160 are sequentially assembled into the handle 100 through the second end opening of the handle 100. 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 aligns with the inner surface of the upper bracket 140 for guidance and alignment. The elastic buckle portion of the upper bracket 140 engages with the groove on the outer surface of the power output shaft 621, thereby securing the oral care element 1000. At this point, the inner end surface of the Y-ring 150 engages with the outer surface of the power output shaft 621, and the outer end surface of the Y-ring 150 abuts against the inner wall of the handle 100, thereby forming a seal around the first end of the handle 100 and preventing liquid in the diversion channel 110 from overflowing from the first end of the handle 100. When a force acting on the oral care element 1000 in a direction away from the handle assembly 2000 is applied, this force overcomes the retaining force of the elastic buckle, separating the power output shaft 621 of the handle assembly 2000 from the upper bracket 140, thereby facilitating replacement of the oral care element 1000.
