Abstract
Description
Technical Field
[0001] The present application relates to the technical field of oral cleaning, and in particular to a brush head and an oral care device. Background Art
[0002] With the continuous improvement of living standards, oral care devices (such as electric toothbrushes) have gradually become a part of many people's daily lives. People's demand for oral care devices is no longer limited to basic cleaning functions, but they are increasingly paying attention to the experience of the cleaning process.
[0003] Currently, some oral care devices achieve effective cleaning of teeth by driving the brush head to vibrate. However, in actual applications, oral care devices have the problem of insufficient vibration amplitude, which leads to insufficient cleaning force. To solve this problem, related technologies have adopted the method of increasing the motor speed or frequency in order to achieve the purpose of enhancing the cleaning force. However, the problem that follows is that when the vibration speed or frequency of the motor during the cleaning process is too high, the cleaning force of the oral care device on the teeth will increase accordingly, resulting in a poor user experience. Utility Model Content
[0004] The embodiments of the present application provide a brush head and an oral care device, which are intended to alleviate the phenomenon of teeth vibration during use of the brush head, thereby improving the comfort of use.
[0005] In a first aspect, an embodiment of the present application provides a brush head, the brush head comprising:
[0006] A brush rod, the brush rod comprising a first connecting rod and a second connecting rod arranged along the length direction, one end of the second connecting rod being connected to a driving member of the oral care device, and the other end being connected to the first connecting rod;
[0007] a soft plastic member, the soft plastic member covering the first connecting rod, the soft plastic member having a front side and a back side oppositely disposed along a thickness direction;
[0008] A hair planting ring, the hair planting ring is embedded in the front surface of the soft rubber part, the hair planting ring has a first hair planting hole, and the soft rubber part fills the gap adjacent to the first hair planting hole; and
[0009] The first bristle bundle includes a fixed end and a free end, and the fixed end is embedded in the first bristle planting hole.
[0010] The brush head in this application solution has at least the following technical effects:
[0011] First, in terms of the connection stability between the brush rod and the hair planting ring, due to the design of the first connecting rod of the brush rod covered by the soft rubber part, the soft rubber part and the first connecting rod have a larger contact area, and the hair planting ring is arranged on the front of the soft rubber part. Therefore, the first connecting rod and the hair planting ring can be stably connected through the soft rubber part.
[0012] Second, in terms of the shock-absorbing effect, since the soft rubber part covers the first connecting rod, it effectively avoids direct exposure of the first connecting rod, thereby preventing the first connecting rod from contacting the user's mouth during use, and in turn increases the contact area of the soft rubber part with the oral cavity during use. Since the material of the soft rubber part is relatively soft and prone to elastic deformation, it can play a better shock-absorbing role, reduce the damage of the brush head to the oral cavity, especially sensitive teeth or sensitive gums, and effectively protect the user's oral cavity.
[0013] As an embodiment of the present application, the projection area of the hair-implanting ring on the front surface at least partially overlaps with the projection area of the first connecting rod on the front surface. This not only makes the spatial layout more compact and reduces unnecessary space waste, but also enables the hair-implanting ring to more effectively utilize the support provided by the first connecting rod, so that the hair-implanting ring can more evenly distribute the pressure when subjected to force, thereby improving the durability and stability of the brush head.
[0014] As an embodiment of the present application, the bristle ring has a plurality of the first bristle holes, or the bristle ring is provided with a plurality of bristle holes, each of which has the first bristle hole. This makes the first bristle bundle layout denser, and the brush head can remove stains and dirt more deeply during the cleaning process, reducing blind spots in cleaning, making cleaning more efficient and thorough.
[0015] As an embodiment of the present application, the first bristle hole is a through hole, so that the first bristle bundle can pass through and be fixed in the first bristle hole of the bristle ring, and the contact area is increased, ensuring that the connection between the bristles and the bristle ring is more firm and not easy to fall off.
[0016] As an embodiment of the present application, the first connecting rod includes a plurality of notches in sequence along the length direction, and at least part of the projection of the hair-planting ring on the front surface of the soft rubber part overlaps with the projection of the notches on the front surface of the soft rubber part. In this way, by setting the notches, the contact area between the first connecting rod and the soft rubber part can be increased, and the fit between the hair-planting ring and the first connecting rod can be made more compact, and the filling of the soft rubber part can be made more uniform and tight, thereby effectively preventing the intrusion of impurities such as moisture and dust, and protecting the cleaning performance of the brush head.
[0017] As an embodiment of the present application, the brush head further includes a bristle planting member, the bristle planting member is connected to the first connecting rod and is provided on a side of the first connecting rod close to the front surface; the bristle planting member has a second bristle planting hole, the soft rubber member covers a portion of the side wall of the bristle planting member, and the brush head further includes a second bristle bundle, and the second bristle bundle is embedded in the second bristle planting hole;
[0018] The hair implanting ring and the hair implanting piece are spaced apart, and the soft rubber piece fills and covers the gap between the hair implanting piece and the hair implanting ring.
[0019] The brush head in the present application solution, by adding a layout of bristle implants, enables the brush head to more comprehensively cover the area to be cleaned during the cleaning process, thereby improving the cleaning efficiency.
[0020] As an embodiment of the present application, in the width direction of the soft rubber part, the hair implant is closer to the middle of the soft rubber part than the hair implant ring, and the width direction, the thickness direction and the length direction are perpendicular to each other. This design helps to improve the stability and functionality of the hair implant in the soft rubber part structure, because the middle position generally provides better support balance. It also helps to optimize the force distribution of the hair implant during use, ensuring the durability and performance of the overall structure.
[0021] As an embodiment of the present application, the length of the second hair transplantation hole along the thickness direction is greater than the length of the first hair transplantation hole along the thickness direction;
[0022] And / or, the aperture of the first hair transplantation hole is larger than the aperture of the second hair transplantation hole.
[0023] In the brush head of this application, the middle area is often the focus of cleaning and is subject to greater force. Therefore, the length of the second bristle pore is greater than the thickness length of the first bristle pore. This ensures the stability of the second bristle bundle after installation. The larger diameter of the second bristle pore ensures that the brush head provides sufficient cleaning force and coverage in this area, allowing users to experience a more efficient and satisfactory cleaning effect during the cleaning process.
[0024] As an embodiment of the present application, when the length of the second hair implantation hole along the thickness direction is greater than the length of the first hair implantation hole along the thickness direction, along the thickness direction, the first connecting rod is recessed on one side close to the hair implantation ring to form an avoidance space, and the avoidance space is used to avoid the hair implantation part.
[0025] The brush head of this application utilizes recessed design to create a clearance space, effectively reducing the ineffective space within the brush head and making the layout of the various components more rational and compact. This not only helps improve the overall performance and stability of the brush head, but also reduces production costs to a certain extent. Furthermore, the clearance space also provides positioning for installation.
[0026] As an embodiment of the present application, the surface of the hair transplanting piece away from the back is flush with the surface of the hair transplanting ring away from the back, and the surface of the hair transplanting piece away from the back protrudes from the front of the soft rubber piece; the hair transplanting piece protruding in this way can more deeply contact and clean the target area, especially those hard-to-reach corners and gaps.
[0027] Alternatively, the surface of the hair implant away from the back is flush with the surface of the hair implant ring away from the back, and the surface of the hair implant away from the back is flush with the front of the soft rubber part. From the perspective of user experience, the flush surface makes the overall touch smoother and more coherent, and the user is less likely to touch the hair implant during use, thereby significantly improving the comfort and satisfaction of use. From a functional perspective, the flush design reduces the difficulty of cleaning.
[0028] As an embodiment of the present application, a plurality of the first hair implantation holes are circumferentially arranged around the second hair implantation holes, so that the hair implantation piece and the hair implantation ring are more compact, thereby facilitating the miniaturization of the brush head.
[0029] As an embodiment of the present application, the bristle implant and the first connecting rod are integrated into one structure. This integrated structure design not only simplifies the overall structure of the brush head and reduces production costs, but also significantly improves the stability and durability of the brush head.
[0030] As an embodiment of the present application, the first implantation holes are at least one of triangular, strip, circular, and rectangular; and / or the second implantation holes are at least one of triangular and strip. In this way, the shapes of the first implantation holes and / or the second implantation holes are varied, and bristles of different cross-sectional shapes can be provided, thereby making the brush head more diverse and providing more comprehensive cleaning effects.
[0031] In a second aspect, an embodiment of the present application provides an oral care device, which includes the above-mentioned brush head and a main body, wherein the driving member of the main body is detachably connected to the brush head. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] In order to make the purpose, technical solutions and advantages of this application clearer, the following part will further describe the embodiments of this application in detail with reference to the accompanying drawings.
[0043] When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0045] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this application belongs. The terms used in this specification are for the purpose of describing specific embodiments only and are not intended to limit this application. The term "and / or" as used herein includes any and all combinations of one or more of the relevant listed items.
[0046] With the continuous improvement of living standards, oral care devices (such as electric toothbrushes) have gradually become a part of many people's daily lives. People's demand for oral care devices is no longer limited to basic cleaning functions, but they are increasingly paying attention to the experience of the cleaning process.
[0047] The first aspect of the present application provides an oral care device, which includes but is not limited to an electric toothbrush, an irrigator, an oral examination device, and the like. The oral care device is described in detail below as an electric toothbrush. Among them, the oral care device includes a main body and a brush head. The main body is designed to be easy for the user to hold, and has built-in core structures such as a driving member (such as a motor) and a control device. The driving shaft of the driving member is connected to the brush head for driving the brush head to vibrate. The brush head is used to penetrate deep into the user's mouth and effectively clean the teeth. In addition, a detachable connection design such as a snap-on connection is adopted between the driving shaft of the driving member and the brush head. This not only makes it easy for the user to operate when the brush head is worn or needs to be replaced, but also ensures the efficient use and long-term maintenance of the oral care device.
[0048] However, in actual use, oral care devices suffer from insufficient vibration amplitude, which in turn leads to insufficient cleaning power. To address this issue, related technologies have adopted the method of increasing the motor speed or frequency to achieve the purpose of enhancing cleaning power. However, the problem that follows is that when the motor vibration speed or frequency during the cleaning process is too high, the oral care device's cleaning power on the teeth will increase accordingly, resulting in a poor user experience.
[0049] To resolve the above issues, please refer to Figures 1 to 4The second aspect of the present application proposes a brush head 100. In an embodiment of the present application, the brush head 100 includes a brush rod 10, a soft rubber part 20, a bristle ring 30 and a first bristle bundle 40.
[0050] The brush rod 10 includes a first connecting rod 11 and a second connecting rod 12 arranged along the length direction. One end of the second connecting rod 12 is connected to the driving member of the oral care device, and the other end is connected to the first connecting rod 11.
[0051] Among them, the first connecting rod 11 and the second connecting rod 12 can be an integrated structure, which enhances the overall structural strength of the brush rod 10 and enables it to withstand greater force and torque during use, thereby extending the service life of the product and improving the user experience. In addition, in order to further enhance the connection stability between the brush rod 10 and the driving member, a plug-in hole can be cleverly provided at the end of the second connecting rod 12 facing away from the first connecting rod 11. This design allows the drive shaft of the driving member to be directly inserted into the plug-in hole, and through a tight plug-in fit, a firm fixation between the two is achieved. This connection method not only simplifies the installation process, but also improves the reliability and durability of the connection. In terms of material selection, the first connecting rod 11 and the second connecting rod 12 can be hard rubber or hard plastic. These materials not only have good processing performance and cost-effectiveness, but also can meet the strength and durability requirements of the brush rod 10 during oral care.
[0052] The soft rubber member 20 covers the first connecting rod 11 and has a front face 21 and a back face 22 disposed opposite each other along its thickness. A bristle ring 30 is embedded in the front face 21 of the soft rubber member 20 and has a first bristle hole 31. A first bristle bundle 40 includes a fixed end 41 and a free end 42, with the fixed end 41 embedded in the first bristle hole 31.
[0053] It can be understood that the fixed end 41 and the free end 42 are the two opposite ends of the first bristle bundle 40 extending in the thickness direction. During the manufacturing process, the fixed end 41 can be set with copper-implanted or copper-free bristle-implanted technology. Both processes can ensure that the fixed end 41 is firmly implanted in the first bristle hole 31 of the bristle ring 30, thereby ensuring the stability and durability of the first bristle bundle 40. The free end 42 is used to contact the user's teeth during use. In addition, the first bristle bundle 40 includes a plurality of brush filaments, which can be straight brush filaments. The straight brush filaments have a simple structure and are easy to manufacture. Alternatively, the brush filaments are arc-shaped brush filaments. For example, the arc-shaped brush filaments can be spiral or S-shaped brush filaments. The arc-shaped brush filaments have a larger projection coverage area on the front 21 and have a larger contact area with the teeth. Exemplarily, the brush filaments can be made of nylon.
[0054] The soft rubber part 20 serves as a bridge connecting the first connecting rod 11 and the hair-planting ring 30. Specifically, it can be coated with the first connecting rod and the hair-planting ring 30 by injection molding, thereby having a stronger bonding strength. Therefore, the soft rubber part 20 has a better connection stability with the first connecting rod and the hair-planting ring 30. Even if the brush head 100 is used for a long time in a high-frequency vibration scenario, the first connecting rod and the hair-planting ring 30 are not easy to fall off.
[0055] As one embodiment of the present application, the hardness of the soft rubber member 20 is not less than 35 Shore hardness and not more than 70 Shore hardness. The materials of the soft rubber member 20 include, but are not limited to, silicone, TPE (Thermoplastic Elastomer), TPU (Thermoplastic polyurethanes), and PVC (Polyvinyl chloride). This ensures that the soft rubber member 20 has appropriate structural strength and elasticity, neither being too hard to affect brushing comfort nor too soft to stably secure the first connecting rod 11.
[0056] In one embodiment of the present application, the thickness of the soft plastic member 20 is not less than 0.4 mm and not greater than 2 mm. This ensures that the soft plastic member 20 has suitable structural strength and elasticity, while maintaining a reasonable material cost. If the thickness of the soft plastic member 20 is less than 0.4 mm, the structural strength and elasticity of the soft plastic member 20 are too low. If the thickness of the soft plastic member 20 is greater than 2 mm, the excessive material consumption leads to increased material costs. Specifically, the thickness of the soft plastic member 20 can be 0.4 mm, 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1.0 mm, etc.
[0057] The brush head 100 in the present application has at least the following technical effects:
[0058] First, in terms of the connection stability between the brush rod 10 and the hair planting ring 30, due to the design of the soft rubber part 20 covering the first connecting rod 11 of the brush rod 10, the soft rubber part 20 and the first connecting rod 11 have a larger contact area, and the hair planting ring 30 is set on the front side 21 of the soft rubber part 20. Therefore, the soft rubber part 20 can achieve a stable connection between the first connecting rod and the hair planting ring 30.
[0059] Second, in terms of the shock-absorbing effect, since the soft rubber part 20 covers the first connecting rod 11, it effectively avoids direct exposure of the first connecting rod 11, thereby preventing the first connecting rod 11 from contacting the user's mouth during use, and in turn increases the contact area of the soft rubber part 20 with the oral cavity during use. Since the material of the soft rubber part 20 is relatively soft and prone to elastic deformation, it can play a better shock-absorbing role, which can reduce the damage of the brush head 100 to the oral cavity, especially sensitive teeth or sensitive gums, and can effectively protect the user's oral cavity.
[0060] See also Figures 2 to 4 As one embodiment of the present application, the projected area of the bristle ring 30 on the front face 21 at least partially overlaps with the projected area of the first connecting rod 11 on the front face 21. From the perspective of structural integration, the projected areas of the bristle ring 30 and the first connecting rod 11 on the front face 21 at least partially overlap, resulting in a more compact spatial layout and reducing unnecessary space waste. This compact layout not only helps enhance the overall aesthetics of the brush head 100, but also makes the product more compact and lightweight while maintaining functionality, making it easier to carry and use. Secondly, from the perspective of functional synergy, the projected areas of the bristle ring 30 and the first connecting rod 11 on the front face 21 overlap, meaning that the bristle ring 30 can more effectively utilize the support provided by the first connecting rod 11. This design allows the bristle ring 30 to distribute pressure more evenly when subjected to force, improving the durability and stability of the brush head 100. At the same time, because the bristle ring 30 and the first connecting rod 11 are closer in space, the interaction between them is more direct and efficient, thereby improving the overall performance of the product.
[0061] Reference Figure 4 As one embodiment of the present application, the bristle ring 30 has a plurality of first bristle holes 31. As another embodiment of the present application, the bristle ring 30 is provided with a plurality of bristle holes 31, and each bristle ring 30 has a first bristle hole 31. In this way, both of the above embodiments will form a plurality of first bristle holes 31 to facilitate the installation of a plurality of first bristle bundles 40. The provision of multiple first bristle holes 31 not only enriches the bristle layout of the brush head 100, but more importantly, it significantly expands the cleaning coverage area of the brush head 100.
[0062] As an embodiment of the present application, the first bristle planting hole 31 is a through hole. The through hole design enables the first bristle planting hole 31 to pass through the bristle planting ring 30, forming a continuous and unobstructed channel. Such a design not only provides great convenience for the installation of the first bristle bundle 40, so that the first bristle bundle 40 can pass through and be fixed in the first bristle planting hole 31 of the bristle planting ring 30, but also increases the contact area, ensuring that the connection between the bristles and the bristle planting ring 30 is more secure and not easy to fall off. This stable connection not only improves the durability of the brush head 100, but also provides a more lasting and stable cleaning effect. When the first bristle bundle 40 is implanted into the first bristle planting hole 31, after the first bristle bundle 40 at least partially passes through the first bristle planting hole 31, the first bristle bundle 40 is fixed to the first bristle planting hole 31 by ultrasonic welding, hot melt welding or laser welding, thereby completing the bristle implantation action. By setting the first bristle planting hole 31 as a through hole, the bristle implantation efficiency of the first bristle bundle 40 can be effectively improved.
[0063] As an embodiment of the present application, refer to Figure 4 The first connecting rod 11 includes a plurality of notches 112 in sequence along the length direction, and the projection of at least part of the bristle ring 30 on the front face 21 of the soft rubber part 20 partially overlaps with the projection of the notch 112 on the front face 21 of the soft rubber part 20. In this way, by setting the notch 112, on the one hand, the contact area between the first connecting rod 11 and the soft rubber part 20 can be significantly increased, so that the soft rubber part 20 can be more tightly and evenly fitted on the side wall of the first connecting rod 11, thereby enhancing the overall structural stability of the brush head 100. On the other hand, due to the increase in contact area, the soft rubber part 20 can better disperse stress when subjected to external force, thereby improving the impact resistance of the brush head 100. On the other hand, since the gaps in the first bristle holes 31 are filled by the soft rubber part 20, during the use of the brush head 100, the soft rubber part 20 can drive the first bristle holes 31 to deform, thereby making the first bristle bundle 40 more fit the curvature of the user's teeth, thereby improving the cleaning effect of the brush head 100. In addition, the projection of the bristle ring 30 coincides with the projection of the gap 112, which means that during the filling process of the soft rubber part 20, the bristle ring 30 can fit tightly around the gap 112 of the first connecting rod 11, so that the bristle ring 30 and the first connecting rod 11 fit more compactly, and the filling of the soft rubber part 20 is also tighter, thereby effectively preventing the intrusion of impurities such as moisture and dust, and protecting the cleaning performance of the brush head 100.
[0064] In an optional embodiment, the surface of the first hair-planting hole 31 on one side near the front surface 21 of the soft rubber member 20 is flush with the front surface 21 of the soft rubber member 20, thereby preventing the user's teeth from colliding with the first hair-planting hole 31 exposed on the soft rubber member 20 when the user cleans the mouth. In another optional embodiment, the surface of the first hair-planting hole 31 on one side near the front surface 21 of the soft rubber member 20 protrudes from the front surface 21 of the soft rubber member 20. This arrangement facilitates the positioning of the soft rubber member 20 during the manufacturing process of the brush head 100 during injection molding, thereby improving the production efficiency of the brush head 100.
[0065] Combined with reference Figure 5 In some structural forms, the brush head 100 further includes a bristle implant 50, which is connected to the first connecting rod 11 and is disposed on a side of the first connecting rod 11 near the front face 21. The bristle implant 50 has a second bristle implant hole 51. The soft rubber member 20 covers at least a portion of the sidewall of the bristle implant 50. The brush head 100 further includes a second bristle bundle 60, which is embedded in the second bristle implant hole 51. The bristle implant ring 30 is spaced apart from the bristle implant 50, and the soft rubber member 20 fills and covers the gap between the bristle implant 50 and the bristle implant ring 30.
[0066] Among them, by adding the bristle implant 50, the brush head 100 can more comprehensively cover the area to be cleaned during the cleaning process, thereby improving the cleaning efficiency. In order to enhance the overall stability and comfort of the brush head 100, the soft rubber part 20 is used to cover at least part of the side wall of the bristle implant 50. The wrapping of the soft rubber part 20 also further enhances the connection strength between the bristle implant 50 and the first connecting rod 11, so that the brush head 100 can remain stable during use. In addition, the bristle implant ring 30 and the bristle implant 50 are arranged at intervals, which provides the necessary space for the filling of the soft rubber part 20. This allows the soft rubber part 20 to fully exert its sealing and buffering effects. The filling of the soft rubber part 20 not only tightly connects the bristle implant ring 30 and the bristle implant 50, but also significantly enhances the overall structural stability of the brush head 100. This tight connection makes the various components of the brush head 100 more stable, thereby improving the impact resistance of the brush head 100, extending its service life, and ensuring reliability during use. It should be noted that, in other embodiments, the hair planting ring 30 and the hair planting member 50 can be directly connected and arranged without the need for additional gaps and filling of the soft rubber member 20. This design simplifies the structure of the brush head 100 to meet different cleaning needs.
[0067] As one embodiment of the present application, the hair implant 50 is closer to the middle of the soft rubber part 20 than the hair implant ring 30 in the width direction of the soft rubber part 20, and the width, thickness and length directions are perpendicular to each other. This design helps to improve the stability and functionality of the hair implant 50 in the structure of the soft rubber part 20, because the middle position generally provides better support and balance. It also helps to optimize the force distribution of the hair implant 50 during use, ensuring the durability and performance of the overall structure.
[0068] Furthermore, the second bristle hole 51 is longer along the thickness direction than the first bristle hole 31. This is because the middle region of the soft rubber component 50 is typically subjected to greater pressure during cleaning. By increasing the length of the second bristle hole 51, this region is more stable after the second bristle bundle 60 is installed, effectively addressing the stresses experienced during cleaning.
[0069] Reference Figure 5 , optionally, the aperture of the second bristle pore 51 is larger than the aperture of the first bristle pore 31. First of all, from the perspective of cleaning efficiency, the larger aperture of the second bristle pore 51 located in the middle of the soft rubber part 20 allows the use of thicker or denser bristle bundles. This design enables the brush head 100 to provide stronger cleaning power and deeper cleaning effects during the cleaning process, especially when dealing with stubborn stains in the central area. And because the central area is often the focus of the cleaning process, the larger aperture of the second bristle pore 51 can ensure that the brush head 100 provides sufficient cleaning power and coverage area in this area, so that the user can feel a more efficient and satisfactory cleaning effect during the cleaning process. At the same time, although the aperture of the first bristle pore 31 in the edge area is smaller, it can also ensure that basic cleaning needs are met, avoiding damage or discomfort caused by excessive cleaning.
[0070] Furthermore, refer to Figure 6Along the thickness direction, the first connecting rod 11 is recessed near the bristle ring 30 to form a relief space 111. This relief space 111 is used to provide space for the bristle implant 50. First, the presence of the relief space 111 makes the overall structure of the brush head 100 more compact. By recessing the relief space 111, the ineffective space within the brush head 100 is effectively reduced, reducing the overall volume of the brush head 100 and making the layout of the various components more reasonable and compact. This not only helps improve the overall performance and stability of the brush head 100, but also reduces production costs to a certain extent. Second, the relief space 111 also has a positioning function, which greatly facilitates the installation process of the brush head 100. When assembling the brush head 100, the presence of the relief space 111 provides a clear positioning reference for the bristle implant 50. The operator can easily install the bristle implant 50 accurately in the designated position based on the position and shape of the relief space 111, without the need for tedious adjustments and proofreading. This not only improves assembly efficiency but also reduces the failure rate caused by improper installation.
[0071] As an embodiment of the present application, the surface of the bristle implant 50 away from the back surface 22 is flush with the surface of the bristle implant ring 30 away from the back surface 22, and the surface of the bristle implant 50 away from the back surface 22 protrudes from the front surface 21 of the soft rubber part 20. First, since the surfaces of the bristle implant 50 and the bristle implant ring 30 are flush, the first bristle bundle 40 and the second bristle bundle 60 can form a tighter arrangement after being embedded, thereby increasing the contact area and friction between the brush head 100 and the surface to be cleaned. This helps to remove stains and dirt more thoroughly and improve cleaning efficiency and effectiveness. The bristle implant 30 that protrudes from the front surface 21 of the soft rubber part 20 can more deeply contact and clean the target area, especially those hard-to-reach corners and gaps.
[0072] As another embodiment of the present application, the surface of the bristle implant 50 away from the back 22 is flush with the surface of the bristle ring 30 away from the back 22, and the surface of the bristle implant 50 away from the back 22 is flush with the front 21 of the soft rubber part 20. From the perspective of user experience, the flush surface makes the overall touch smoother and more coherent, and the user is not likely to touch the bristle implant 50 during use, thereby significantly improving the comfort and satisfaction of use. From a functional point of view, the flush design reduces the difficulty of cleaning. From an aesthetic point of view, the flush design makes the overall appearance of the brush head 100 smoother and neater, and improves the visual beauty of the brush head 100.
[0073] It can be understood that, as another embodiment of the present application, the surface of the bristle implant 50 away from the back 22 protrudes from the surface of the bristle implant ring 30 away from the back 22, and the surface of the bristle implant ring 30 away from the back 22 is flush with the front 21 of the soft rubber part 20. In this way, during the manufacturing process of the brush head 100, the bristle implant 50 can be used to facilitate the positioning of the brush head 100, thereby improving the manufacturing efficiency of the brush head 100. In addition, since the bristle implant 50 is arranged on the inner side of the first bristle implant hole 31, when the user uses the brush head 100, the user's teeth will only be released from the first bristle bundle 40 or the second bristle bundle 60, thereby preventing the user's teeth from hitting the internal bristle implant 50.
[0074] Reference Figure 5 As an embodiment of the present application, a plurality of bristle rings 30 are arranged along the circumference of the bristle member 50. These first bristle holes 31 are circumferentially distributed around the second bristle holes 51, forming a tight and orderly arrangement. Such a layout enables the first bristle bundle 40 to cover the surface to be cleaned more comprehensively, and both flat areas and uneven corners can be effectively cleaned. In addition, the design of the plurality of first bristle holes 31 arranged circumferentially around the second bristle holes 51 makes the layout of the first bristle bundle 40 denser, and the brush head 100 can remove stains and dirt more deeply during the cleaning process, reducing cleaning dead corners, and making the cleaning work more efficient and thorough.
[0075] Combined with reference Figure 5 As an embodiment of the present application, the bristle implant 50 and the first connecting rod 11 are an integrated structure. The design of this integrated structure not only simplifies the overall structure of the brush head 100 and reduces production costs, but also significantly improves the stability and durability of the brush head 100. Since no additional connecting parts are required between the bristle implant 50 and the first connecting rod 11, the failure rate caused by loose or damaged connections is reduced. In addition, the design of the integrated structure also makes the connection between the bristle implant 50 and the first connecting rod 11 tighter and more stable. This tight connection not only improves the impact resistance of the brush head 100, but also makes the brush head 100 more durable and reliable during use.
[0076] As an embodiment of the present application, a plurality of first hair implantation holes 31 are circumferentially arranged around the second hair implantation holes 51. Exemplarily, the shape of the first hair implantation holes 31 is at least one of a triangle, a strip, a circle, a rectangle, a square, an ellipse, a polygon, a semicircle, and an arc. This embodiment is not limited to this. The shape of the first hair implantation holes 31 is diverse, and bristles of different cross-sectional shapes can be provided, so that the types of the brush heads 100 are more diverse and the teeth cleaning effects are richer. Similarly, the shape of the second hair implantation holes can also be at least one of a triangle, a strip, a circle, a rectangle, a square, an ellipse, a polygon, a semicircle, and an arc.
