Description

Technical Field

[0001] This application relates to the field of oral hygiene technology, and more particularly to a brush head and oral care device. Background Technology

[0002] With increasing emphasis on personal hygiene and health, oral hygiene is receiving more and more attention. A toothbrush head consists of bristle attachments and a connecting rod for securing them. To enhance cleaning effectiveness, the bristle tips are typically designed with different curved or toothed shapes. However, different users have different tooth shapes, and even different parts of the same user's teeth can vary in shape. It's difficult for the bristles to perfectly match the tooth shape, resulting in ineffective contact with all teeth and affecting the toothbrush's cleaning performance. Utility Model Content

[0003] The main objective of this application is to provide a brush head and an oral care device.

[0004] Firstly, this application provides a brush head, comprising:

[0005] A brush handle, the brush handle including opposing first and second ends, the first end of the brush handle being detachably connected to the main unit of an oral care device;

[0006] A brush plate, the brush plate including a support part and a connecting part, the support part being connected to the second end of the brush handle, and the connecting part being connected to the support part;

[0007] A hair-planting assembly, comprising at least a first hair-planting plate having a first hair-planting area and a second hair-planting plate having a second hair-planting area, wherein the first hair-planting plate is connected to the support portion via the connecting portion, and the second hair-planting plate is disposed at one end of the first hair-planting plate and connected to the support portion, wherein a gap is formed between the first hair-planting plate and the second hair-planting plate, and / or a gap is formed between the first hair-planting plate and the support portion;

[0008] The bristles, at least some of which are disposed in the first bristle planting area and the second bristle planting area, and the connecting portion can deform to change the relative position of the first bristle planting plate and the second bristle planting plate when the bristles located in the first bristle planting area are subjected to force.

[0009] A soft rubber component that covers at least a portion of the back and peripheral sides of the brush plate and fills at least a portion of the gaps.

[0010] As can be seen from the above implementation scheme description, when the bristles located in the first bristle implantation area are subjected to force, the connecting part can deform to change the relative position of the first bristle implantation plate and the second bristle implantation plate. As a result, when the first bristle implantation plate swings relative to the second bristle implantation plate following the deformation of the connecting part, the bristles provided on the first bristle implantation plate can adjust the relative position between the bristles and the target to be cleaned (such as the tooth surface or gap) according to the swing of the first bristle implantation plate. This allows the bristles to adapt to various tooth surfaces, and ultimately can effectively enhance the cleaning effect of the bristles on the teeth and improve brushing efficiency.

[0011] Meanwhile, the soft rubber parts cover at least part of the back and sides of the brush plate, which can effectively reduce the discomfort caused by unnecessary collisions between the back and sides of the brush plate and teeth in the mouth during oral cleaning with an oral care device with a brush head, thus improving the comfort of oral cleaning.

[0012] Furthermore, by filling at least part of the gaps inside the brush head with soft rubber components, the connection part of the brush head can be deformed, while the overall strength of the brush head can also be effectively enhanced.

[0053] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0054] In the description of this application, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0055] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0056] Please see Figure 1 and Figure 2 , Figure 1 This is a three-dimensional structural diagram of an oral care device provided in an embodiment of this application.

[0057] like Figure 1 and Figure 2As shown, the oral care device 100 includes a main unit 20 and a brush head 10. The main unit 20 includes a drive component 21 and a control component 22 connected to the drive component 21. The drive component 21 is detachably connected to the brush head 10 and is used to drive the brush head 10 to move. The user can trigger the control component 22 by pressing, sliding, pushing, pulling, etc., so as to control the drive component 21 to perform corresponding actions. It can be understood that the oral care device 100 includes, but is not limited to, an electric toothbrush.

[0058] Optionally, the drive assembly 21 and the brush head 10 can be detachably connected in ways including but not limited to structural engagement and threaded connection. Typically, after a period of use, the cleaning effectiveness of the brush head 10 of the oral care device 100 will decrease or it will become contaminated. This may lead to a decline in oral hygiene or even affect human health, thus requiring periodic replacement. Therefore, the detachable connection between the drive assembly 21 and the brush head 10 allows the oral care device 100 to be replaced only with the brush head 10 when replacement is needed, avoiding unnecessary waste.

[0059] For example, the control component 22 is connected to the electric motor of the drive component 21 via a connecting wire to supply power to the drive component 21, thereby driving the drive component 21 to move and thus driving the brush head 10 to operate. The drive component 21 includes an electric motor, and the brush head 10 can be detachably connected to the output shaft of the electric motor. The brush head 10 can vibrate under the drive of the electric motor to clean the inside of the oral cavity.

[0060] Optionally, the electric motor can be set with different vibration modes, such as fast vibration, medium vibration and interval vibration, so that the brush head 10 can vibrate in different ways, and users can choose according to their own usage habits.

[0061] Optionally, the control component 22 includes a trigger switch, a circuit board, and a power supply module, the power supply module including but not limited to a battery. The user performs a corresponding trigger operation on the trigger switch, causing the trigger switch to output a corresponding trigger signal to the circuit board. The circuit board then controls the drive component 21 and the power supply module of the host 20 to perform corresponding operations based on the received trigger signal, such as powering on, powering off, and selecting vibration mode.

[0062] Please see Figures 3 to 6 In some embodiments, the brush head 10 includes a handle 11, a brush plate 12, a bristle assembly 13, bristles 14, and a soft rubber component 15. The handle 11 includes a first end 11a and a second end 11b, the first end 11a of which is detachably connected to the main unit 20 of the oral care device 100. Optionally, the detachable connection between the handle 11 and the main unit 20 includes, but is not limited to, threaded connection, structural engagement, interference fit, etc.

[0063] The brush plate 12 includes a support portion 121 and a connecting portion 122. The support portion 121 is connected to the second end 11b of the brush handle 11, and the connecting portion 122 is connected to the support portion 121. Figure 4 As shown.

[0064] The tufting assembly 13 includes at least a first tufting plate 131 having a first tufting area 1311 and a second tufting plate 132 having a second tufting area 1321. The first tufting plate 131 is connected to the support portion 121 via a connecting portion 122, and the second tufting plate 132 is disposed at one end of the first tufting plate 131 and connected to the support portion 121. A gap 17 is formed between the first tufting plate 131 and the second tufting plate 132, and / or a gap 17 is formed between the first tufting plate 131 and the support portion 121.

[0065] At least some of the bristles 14 are disposed in the first bristle implantation area 1311 and the second bristle implantation area 1321. When the bristles 14 located in the first bristle implantation area 1311 are subjected to force, the connecting part 122 can deform, thereby causing the first bristle implantation plate 131 to swing or move, so as to change the relative position of the first bristle implantation plate 131 and the second bristle implantation plate 132. This allows the bristles 14 disposed in the first bristle implantation area 1311 to swing or move with the first bristle implantation plate 131. Ultimately, the relative position between the bristles 14 and the target to be cleaned (such as the tooth surface or gaps) can be adjusted. This allows the bristles 14 of the brush head 10 to adapt to various tooth surfaces when the user is cleaning their teeth. The overall position of the bristles 14 can be changed according to the different forces applied by the user when brushing their teeth, which can effectively enhance the cleaning effect of the bristles 14 on the teeth and improve brushing efficiency.

[0066] The soft rubber part 15 covers at least a portion of the back and peripheral sides of the brush plate 12 and fills at least a portion of the gaps. Optionally, the back of the brush plate 12 includes at least a support portion 121 on the side surface away from the bristles 14, and the peripheral side of the brush plate 12 includes at least a connecting portion 122 on the peripheral side surface in the direction perpendicular to the extension of the brush handle 11.

[0067] It is understood that the way the bristles 14 are set in the first bristle planting area 1311 and the second bristle planting area 1321 can be that bristle planting holes are provided in the first bristle planting area 1311 and the second bristle planting area 1321, and one end of the bristles 14 is fixed to the corresponding bristle planting area through the bristle planting holes. The shape of the bristle planting holes can be square, arc, polygon, etc., and there is no limitation here.

[0068] As can be seen from the above implementation scheme description, when the bristles 14 located in the first bristle implantation area 1311 are subjected to force, the connecting part 122 can deform to change the relative position of the first bristle implantation plate 131 and the second bristle implantation plate 132. This allows the bristles 14 located on the first bristle implantation plate 131 to adjust the relative position between the bristles 14 and the target to be cleaned (such as the tooth surface or gap) as the first bristle implantation plate 131 tilts relative to the second bristle implantation plate 132 following the tilt of the first bristle implantation plate 131. This allows the bristles 14 to adapt to various tooth surfaces, ultimately effectively enhancing the cleaning effect of the bristles 14 on the teeth and improving brushing efficiency. It is understood that changing the relative position of the first bristle implantation plate 131 and the second bristle implantation plate 132 can be a relative positional shift between the first bristle implantation plate 131 and the second bristle implantation plate 132, or a relative angular shift between the first bristle implantation plate 131 and the second bristle implantation plate 132. No limitation is made here.

[0069] Meanwhile, the soft rubber part 15 covers at least part of the back and peripheral sides of the brush plate 12, thereby effectively reducing the discomfort caused by unnecessary collisions between the back and peripheral sides of the brush plate 12 and teeth in the mouth during oral cleaning with the oral care device 100 with the brush head 10, thus improving the comfort of oral cleaning.

[0070] Furthermore, by filling at least part of the gap 17 inside the brush head with the soft rubber part 15, the connecting part 122 of the brush head can be deformed, which not only strengthens the bonding between the soft rubber part 15 and the brush plate 12, but also effectively enhances the overall strength of the brush head.

[0071] In some embodiments, when the bristles 14 located in the first bristle-planting area 1311 are subjected to force, the first bristle-planting plate 131 can at least sway relative to the support portion 121 along a first direction and a second direction, the first direction being the extension direction of the brush handle 11, and the second direction being set at an angle to the first direction. Optionally, the first direction and the second direction are perpendicular to each other.

[0072] like Figure 5As shown, the first direction is the direction extending along the handle 11, which is also the length direction of the handle 11, i.e., the X-axis extension direction; the second direction is the vertical direction and perpendicular to the first direction, i.e., the Z-axis extension direction; and the third direction is the Y-axis extension direction. When the bristles 14 of the first bristle implantation area 1311 are under force, the first bristle implantation plate 131 can deflect relative to the support part 121 in at least two different directions, namely the first direction and the second direction. That is, the first bristle implantation plate 131 can deflect in the horizontal direction extending along the handle 11 and in the vertical direction perpendicular to the horizontal direction extending along the handle 11. On the one hand, this allows the bristles 13 to adapt to various tooth surfaces. On the other hand, during the brushing process, the brush plate 12 constantly changes position in the user's mouth, and the first bristle implantation plate 131 can deflect more quickly, thus better conforming to the user's tooth surface, ultimately effectively enhancing the cleaning effect of the bristles 13 on the teeth and improving brushing efficiency.

[0073] Please see Figure 2 and Figure 7 In some embodiments, the projection of the connecting portion 122 along the first direction onto the first hair-planting plate 131 is located in the middle region of the first hair-planting plate 131, or the projection of the connecting portion 122 along the first direction onto the first hair-planting plate 131 is located on one side edge of the first hair-planting plate 131, where the first direction is the extending direction of the brush handle 11.

[0074] For example, one end of the connecting portion 122 is connected to the middle region of the first flocking plate 131, so that the projection of the connecting portion 122 along the first direction onto the first flocking plate 131 is located in the middle region of the first flocking plate 131. Alternatively, one end of the connecting portion 122 is connected to one side edge of the first flocking plate 131, so that the projection of the connecting portion 122 along the first direction onto the first flocking plate 131 is located on one side edge of the first flocking plate 131.

[0075] After the first bristle plate 131 is connected to the support part 121 by the connecting part 122 in the above-mentioned connection method, the first bristle plate 131 is more likely to swing relative to the support part 121 or swing to a greater extent under the action of external force, thereby making the bristles 13 have more contact angles with the teeth, which can effectively enhance the cleaning effect of the bristles 13 on the teeth and improve the brushing efficiency.

[0076] In an optional embodiment, one end of the connecting part 122 is connected to the middle area of ​​the first bristle plate 131. When the bristles 14 on the first bristle plate 131 are subjected to force, the first bristle plate 131 can tilt or sway more flexibly in different directions, thereby improving the adaptability of the bristles 14 and the user's tooth surface more flexibly according to the force on the bristles 14 on the first bristle plate 131.

[0077] In an optional embodiment, one end of the connecting portion 122 is connected to one side edge of the first bristle plate 131. When the bristles 14 on the first bristle plate 131 are subjected to force, compared to when one end of the connecting portion 122 is connected to the middle area of ​​the first bristle plate 131, the user only needs to apply less force when brushing to achieve a positional change between the first bristle plate 131 and the second bristle plate 132, thereby reducing the difficulty of adapting the bristles 14 to the user's tooth surface. For example, when one end of the connecting portion 122 is connected to one side edge of the first bristle plate 131 along the extension direction of the brush handle 11, the first bristle plate 131 is more likely to change position on the side away from the connecting portion 122 along the extension direction of the brush handle 11. When one end of the connecting portion 122 is connected to one side edge of the first bristle plate 131 along a third direction, the first bristle plate 131 is more likely to change position on the side away from the connecting portion 122 along a third direction. In some embodiments, the support portion 121 has a first support projection on the first tufting plate 131, the width of the first support projection in the third direction being smaller than the width of the first tufting plate 131, and the third direction being perpendicular to the extension direction of the brush handle 11.

[0078] like Figure 7 As shown, the support portion 121 forms a first notch and a second notch on opposite sides in the first direction. The first tufting member 121 is partially exposed in at least one of the first and second notches. That is, the first tufting member 121 has a first projection in the second direction, and the first projection is at least partially located within the first notch and / or the second notch. Furthermore, the support portion 121 has a first support projection on the first tufting plate 131. The width of the first support projection is the width of the support portion 121 above the first tufting plate 131. The projection width of the first support projection in the Y-axis direction is D2, and the width of the first tufting member 12 in the Y-axis direction is D1, where D1 > D2.

[0079] Since the width of the projection of the support portion 121 onto the first hair-planting plate 131 is smaller than the width of the first hair-planting plate 131, when the first hair-planting plate 131 is subjected to force, at least one edge of the first hair-planting plate 131 is not rigidly supported by the support portion 121, making it easier for the first hair-planting plate 131 to deform along the first direction. Consequently, under the action of external force, the first hair-planting plate 131 can swing relative to the support portion 121 on opposite sides along the first direction, or the swing amplitude can be greater.

[0080] In some embodiments, the first flocking plate 131 has a thickening member in the edge region in the third direction. Alternatively, the thickness of the first flocking plate 131 in the edge region in the third direction is greater than the thickness in the non-edge region in the third direction, and the connecting portion 122 connects the non-edge region of the first flocking plate 131.

[0081] like Figure 8A and Figure 8B As shown, the thickness of the edge region of the first bristle-planting plate 131 is D3, and the thickness of the non-edge region of the first bristle-planting plate 131 is D4, where D3 > D4. This means that the edge region of the first bristle-planting plate 131 is thickened, making it easier for the connecting part 122 to deform when an external force is applied to the edge of the first bristle-planting plate 131. In addition, when the bristle-planting method of the brush head 10 is copper bristle-planting, setting the thickness of the edge region of the first bristle-planting plate 131 to be greater than the thickness of the non-edge region of the bristle-planting plate 131 ensures that the first bristle-planting plate 131 has better structural strength when bristling the brush head 10, providing structural support for the bristle-planting process.

[0082] In some embodiments, the connecting portion 122 is strip-shaped, wherein the length of the connecting portion 122 along the length direction is greater than its width along the width direction, or the width of the connecting portion 122 along the width direction is greater than its length along the length direction. For example, the connecting portion 122 is elongated, rectangular, or cylindrical. The length of the connecting portion 122 along the length direction is the extension length of the connecting portion 122 along the first direction, and the width of the connecting portion 122 along the width direction is the extension width of the connecting portion 122 along the third direction. The extension length and width in the two directions are different. By setting the connecting portion 122 to be strip-shaped and setting the thickness of the connecting portion 122 in the length and width directions to different dimensions, it is convenient for the connecting portion 122 to deform under the trigger of external force.

[0083] In some embodiments, the cross-sectional area of ​​the connecting portion 122 gradually decreases from the connection end with the support portion 121 toward the connection end with the first flocking plate 131, such as... Figure 9A As shown.

[0084] Optionally, the cross-sectional area of ​​the connecting portion 122 gradually increases from the connection end with the support portion 121 toward the connection end with the first flocking plate 131, such as... Figure 9B As shown.

[0085] Optionally, the cross-sectional area of ​​the connecting portion 122 first decreases and then increases from the connection end with the support portion 121 toward the connection end with the first flocking plate 131, such as... Figure 9C As shown.

[0086] The above-mentioned connection part 122 is designed to thin the connection structure between the support part 121 and the first flocking plate 131, thereby making the connection part 122 more prone to deformation under external force.

[0087] In some embodiments, the cross-sectional area of ​​the connecting portion 122 is the same from the connecting end with the support portion 121 toward the connecting end with the first flocking plate 131, such as... Figure 9DAs shown. The manufacturing process of the connecting part 122 formed in this embodiment is relatively simple, and the product yield is high.

[0088] like Figures 4 to 6 As shown, in some embodiments, the second tufting plate 132 is disposed at the end of the first tufting plate 131 away from the brush handle 11, and a gap 17 is formed between the second tufting plate 132 and the first tufting plate 131. It can be understood that the second tufting plate 132 and the support portion 121 can be rigidly connected or non-rigidly connected.

[0089] For example, the second tufting plate 132 is rigidly connected to the support portion 121. Since the second tufting plate 132 is located at the end of the first tufting plate 131 away from the brush handle 11, if the head of the brush head 10 falls, the second tufting plate 132 will usually contact the ground first. Compared with the first tufting plate 131, the connection strength between the second tufting plate 132 and the support portion 121 is higher, thereby effectively protecting the swingable first tufting plate 131 and preventing the brush head 10 from falling and causing damage to the connection portion 122. In addition, the rigid connection between the second tufting plate 132 and the support portion 121 can effectively transmit the driving force of the drive component 21 to the second tufting plate 132 through the support portion 121, thereby reducing the vibration attenuation of the second tufting plate 132.

[0090] For example, the second bristle plate 132 is not rigidly connected to the support portion 121. That is, the second bristle plate 132 can tilt relative to the brush handle 11. For example, at least when the bristles 14 located in the second bristle area 1321 are under force, the second bristle plate 132 can tilt at least in a second direction, which is the direction perpendicular to the extension direction of the brush handle 11. Since both the first bristle plate 131 and the second bristle plate 132 can tilt at corresponding angles, more bristles 13 have more contact angles with the teeth, which can effectively enhance the cleaning effect of the bristles 13 on the teeth and improve brushing efficiency.

[0091] In some embodiments, the second tufting plate 132 is disposed at the end of the first tufting plate 131 away from the brush handle 11, and forms a gap 17 between the two. The support portion 121 connected to the second tufting plate 132 is an arc-shaped structure protruding away from the first tufting plate 131. By designing the support portion 121 as an arc-shaped structure, the discomfort of the brush head 10 touching the teeth during use can be effectively reduced, and the comfort of oral care can be improved.

[0092] In some embodiments, the support portion 121 includes a first section. The projection of the first section on the brush plate 12 is located in the gap between the first tufting plate 131 and the second tufting plate 132. The cross-section of the first section on the plane forming the second and third directions is elongated or rectangular. This arrangement ensures that the support portion 121 has a certain structural strength, preventing the support portion 121 from breaking in the first section when the brush head 10 is dropped, thus affecting the life of the brush head. On the other hand, it increases the deformation of the second tufting plate 132, ensuring that the second tufting plate 132 can undergo slight swaying or torsion.

[0093] In some embodiments, the deformation of the second bristle plate 132 toward the side closer to the bristles 14 is greater than the deformation toward the side farther from the bristles 134. When the user cleans their mouth, when the user's oral tissues are pressed against the back of the second bristle plate 132, the second bristle plate 132 can deform more easily toward the bristles 14, thereby making it easier to clean the inside of the user's teeth and improving the cleaning effect of the brush head 10.

[0094] In some embodiments, the sidewall of the second flocking plate 132 near the first flocking plate 131 protrudes, and the sidewall of the first flocking plate 131 near the second flocking plate 132 is recessed. Alternatively, the sidewall of the second flocking plate 132 near the first flocking plate 131 is recessed, and the sidewall of the first flocking plate 131 near the second flocking plate 132 protrudes, as shown below. Figure 6 As shown, this design allows the bristle holes of the first bristle plate 131 and the second bristle plate 132 to be arranged along the edges of their adjacent sidewalls, thereby effectively increasing the longitudinal density of the bristle holes between the second bristle plate 132 and the first bristle plate 131, and improving the bristle density of the brush head.

[0095] In some embodiments, the projection of the support portion 121 along the first direction onto the second hair-planting plate 132 is located in the middle region of the second hair-planting plate 132, or the projection of the support portion 121 along the first direction onto the second hair-planting plate 132 is located on one side edge of the second hair-planting plate 132, where the first direction is the extending direction of the brush handle 11.

[0096] like Figure 4 As shown, one end of the support portion 121 is connected to the middle region of the second flocking plate 132, so that the projection of the support portion 121 along the first direction onto the second flocking plate 132 is located in the middle region of the second flocking plate 132. Alternatively, one end of the support portion 121 is connected to one side edge of the second flocking plate 132, so that the projection of the support portion 121 along the first direction onto the second flocking plate 132 is located on one side edge of the second flocking plate 132.

[0097] After the second bristle plate 132 is connected to the support part 121 by the above connection method, the second bristle plate 132 is more likely to swing under the action of external force or the swing amplitude is greater, thereby making the bristles 13 have more contact angles with the teeth, which can effectively enhance the cleaning effect of the bristles 13 on the teeth and improve the brushing efficiency.

[0098] In some embodiments, the second bristle plate 132 is disposed at the end of the first bristle plate 131 near the brush handle 11, forming a gap between them. Optionally, the second bristle plate 132 is not rigidly connected to the support portion 121, meaning the second bristle plate 132 can tilt relative to the brush handle 11. For example, at least when the bristles 14 located in the second bristle area 1321 are under force, the second bristle plate 132 can tilt at least in a second direction, which is the direction perpendicular to the extension direction of the brush handle 11. Since both the first bristle plate 131 and the second bristle plate 132 can tilt at corresponding angles, more bristles 13 have more contact angles with the teeth, effectively enhancing the cleaning effect of the bristles 13 on the teeth and improving brushing efficiency.

[0099] like Figures 4 to 6 As shown, in some embodiments, the brush head 10 further includes a third bristle plate 133, which is disposed at one end of the first bristle plate 131 near the brush handle 11 and connected to the support portion 121. The third bristle plate 133 forms a third bristle area 1331, and some bristles 14 are disposed in the third bristle area 1331.

[0100] Optionally, the third bristle plate 133 is rigidly connected to the support part 121. Through the rigid connection, the third bristle plate 133 can better avoid vibration attenuation caused by non-rigid connection, thereby ensuring the cleaning power of the bristles of the third bristle plate 133.

[0101] In some embodiments, the support portion 121 includes a second section. The projection of the second section on the brush plate 12 is located in the gap between the second tufting plate 132 and the third tufting plate 133. The cross-section of the second section on the plane forming the second and third directions is elongated or rectangular. This arrangement ensures that the support portion 121 has a certain structural strength, preventing the support portion 121 from breaking in the second section when the brush head 10 is dropped, thus affecting the life of the brush head. On the other hand, it increases the deformation of the first tufting plate 131, ensuring that the first tufting plate 131 can undergo slight swaying or torsion.

[0102] It is understood that the way the bristles 14 are set in the third bristle planting area 1331 includes, but is not limited to, the third bristle planting area 1331 being provided with bristle planting holes, and the bristles 14 being fixed in the third bristle planting area 1331 through the bristle planting holes.

[0103] Optionally, the sidewall of the third tufting plate 133 near the first tufting plate 131 protrudes, while the sidewall of the first tufting plate 131 near the third tufting plate 133 is recessed. Alternatively, the sidewall of the third tufting plate 133 near the first tufting plate 131 is recessed, while the sidewall of the first tufting plate 131 near the third tufting plate 133 protrudes. This design effectively increases the density of the tufting holes between the third tufting plate 133 and the first tufting plate 131, effectively reducing the spacing of the bristles 14 between the first and third tufting plates 131, and increasing the bristle density of the brush head.

[0104] Optionally, the projection of the support portion 121 onto the third bristle plate 133 along the first direction is located in the middle region of the third bristle plate 133, and the first direction is the extension direction of the brush handle 11.

[0105] like Figure 4 or Figure 6 As shown, one end of the support portion 121 is connected to the middle region of the third flocking plate 133, so that the projection of the support portion 121 along the first direction on the third flocking plate 133 is located in the middle region of the third flocking plate 133.

[0106] Please see Figure 10 In some embodiments, the third bristle plate 133 is connected to the support portion 121, and the brush handle 11 and the connecting portion 122 are connected through the support portion 121. At the same time, there is a gap between the third bristle plate 133 and the support portion 121, and there is also a gap between the third bristle plate 133 and the first bristle plate 131. This allows the support portion 121 connected to the third bristle plate 133 to deform under stress, thereby causing the first bristle plate 131 to sway, which in turn effectively enhances the cleaning effect of the bristles 13 on the teeth and improves brushing efficiency.

[0107] Optionally, the projection of the support portion 121 on the third tufting plate 133 along the first direction is located in the middle region of the third tufting plate 133, or the projection of the support portion 121 on the third tufting plate 133 along the first direction is located on one side edge of the third tufting plate 133, where the first direction is the extension direction of the brush handle 11.

[0108] Please see Figure 11 In some embodiments, the first flocking plate 131 includes a first flocking component 131a and a second flocking component 131b, both of which are provided with bristles 14. The first flocking component 131a and the second flocking component 131b are spaced apart in the horizontal direction, and are respectively connected to the support portion 121 via corresponding connecting portions 122.

[0109] Optionally, the first bristle implantation component 131a and the second bristle implantation component 131b may deflect relative to the brush handle 11 at least in the first and second directions.

[0110] Since the connecting part 122 can deform under the action of external force, the first bristle implantation part 131a and the second bristle implantation part 131b can be tilted relative to the brush handle 11, thereby allowing more bristles 13 to have more contact angles with the teeth, which can effectively enhance the cleaning effect of the bristles 13 on the teeth and improve brushing efficiency.

[0111] It is understood that the way in which the first hair-planting component 131a and the second hair-planting component 131b are both provided with bristles 14 is that the first hair-planting component 131a and the second hair-planting component 131b both form corresponding hair-planting areas, and the bristles 14 are fixedly disposed within the hair-planting areas formed by the first hair-planting component 131a and the second hair-planting component 131b.

[0112] In some embodiments, the connecting portion 122 is located at one end close to the first hair-planting component 131a and the second hair-planting component 131b, or at one end far from each other. This connection method allows the first hair-planting component 131a and the second hair-planting component 131b to more easily apply force to the connecting portion 122 under external force, thereby causing the connecting portion 122 to deform and allowing the first hair-planting component 131a and the second hair-planting component 131b to swing.

[0113] In some embodiments, when the connecting portion 122 is provided at one end close to the first bristle implantation component 131a and the second bristle implantation component 131b, the bristles 14 at the ends far apart from each other have a first height, and the bristles 14 at the ends close to each other have a second height, with the first height being greater than the second height. With this arrangement, the user can more easily access the bristles with the first height when cleaning their mouth. Because the bristles with the first height are located at the ends far apart from each other, the teeth can more easily cause the first bristle implantation plate 131 to shift position upon contact with the bristles with the first height, thereby better adapting to the user's dental condition and effectively improving oral cleaning.

[0114] like Figure 11As shown, in some embodiments, the first bristle implantation plate 131 further includes a third bristle implantation component 131c, which is disposed between the first bristle implantation component 131a and the second bristle implantation component 131b and connected to the support portion 121. Optionally, the third bristle implantation component 131c is rigidly connected to the support portion 121. When the user cleans their mouth, the first bristle implantation components 131a and the second bristle implantation component 131b on both sides of the third bristle implantation component 131c can more flexibly shift their positions and more flexibly adapt to the user's tooth surface, thereby improving the cleaning effect of the bristles 14 on the first bristle implantation components 131a and the second bristle implantation component 131b.

[0115] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the scope of the technology disclosed in this application, and these modifications or substitutions should all be covered within the scope of protection of this application.
