Description

Technical Field

[0001] The present disclosure relates to the technical field of cleaning equipment, and more specifically, to a brush head and a toothbrush. Background Art

[0002] Teeth cleaning is essential for maintaining oral health and overall physical health. Regular teeth cleaning can remove dental plaque and reduce the risk of periodontal disease. If dental plaque is not removed in time, it will harden to form tartar, irritate the gums, cause gingivitis and even periodontitis, and eventually cause teeth to loosen and fall out.

[0003] The brush head designs of existing manual toothbrushes and single-mode electric toothbrushes are relatively uniform, lacking special designs for special areas such as the gaps between teeth and the gingival sulcus. When performing oral cleaning, it is difficult to clean areas with more complex structures, such as the triangular area (gingival sulcus) adjacent to the teeth and gums, which is not conducive to maintaining oral health.

[0058] The present disclosure provides a brush head and a toothbrush, wherein the brush head includes a brush head body, a cleaning part, and a transmission part. The brush head body extends along a first axis and includes a side wall defining an open cavity, and a support member is formed on the side wall.

The first cleaning unit and the second cleaning unit are used to clean the tooth surface of the teeth, and the second cleaning unit is configured to be pivotable. The transmission part is at least partially disposed in the cavity and includes a first transmission member and a second transmission member, wherein the first transmission member is configured to cooperate with the cleaning part and is driven by a power source to drive the cleaning part to vibrate; the second transmission member cooperates with the support member and extends along the first axis. One end of the second transmission member is configured to cooperate with the first transmission member, and the other end is configured to eccentrically cooperate with the second cleaning unit; when the first transmission member is driven by the power source, it also drives one end of the second transmission member to swing, and the second transmission member uses the support member as a fulcrum so that its other end drives the second cleaning unit to rotate.

[0059] The toothbrush provided by the present disclosure includes a handheld portion and a brush head as described above, wherein the handheld portion is configured to be held; the brush head as described above is configured to be mounted on the handheld portion, and the cleaning portion of the brush head is configured to vibrate relative to the handheld portion.

[0060] The brush head provided by the present disclosure can effectively remove dental plaque and food debris through the vibration of the first cleaning unit and the rotation of the second cleaning unit, reducing the formation of dental calculus and thereby reducing the risk of gingivitis and periodontitis. In addition, the pivotable nature of the cleaning unit can adapt to the oral structure of different users, especially for hard-to-reach areas such as the gingival sulcus, so that the brush head can better fit the tooth surface and gum line, thereby achieving more comprehensive and thorough cleaning. Not only does it improve cleaning efficiency, it can also promote the user's oral health. Long-term use can help prevent problems such as loose teeth and tooth loss.

[0061] The toothbrush provided by this disclosure, through the combination of a handheld portion and a brush head, can effectively clean the complex areas adjacent to teeth and gums, particularly hard-to-reach areas such as the gingival sulcus. The cleaning portion of the brush head can vibrate relative to the handheld portion, which not only enhances plaque removal but also penetrates deep into the gaps between teeth and the gingival sulcus to remove stubborn stains and bacteria, significantly reducing the risk of periodontal disease. Furthermore, it can reduce tartar formation, protect gum health, avoid gingivitis and periodontitis, and prevent tooth loosening and loss, thereby improving the efficiency and quality of oral cleaning.

[0062] For ease of understanding, refer to Figures 1 to 6 , the specific structure and working principle of the brush head and toothbrush disclosed in the present invention are explained in detail with reference to an embodiment.

[0063] like Figure 1 and Figure 3 As shown, in the first aspect of the present disclosure, the present disclosure provides a brush head, comprising: a brush head body 1, the brush head body 1 is configured to extend along a first axis, and includes a side wall defining an open cavity, and a support member 2 is formed on the side wall; a cleaning portion 3 attached to one end of the brush head body 1, and the cleaning portion 3 is pivotable relative to the body; the cleaning portion 3 includes a first cleaning unit 31 and a second cleaning unit 32, and the second cleaning unit 32 is configured to be pivotable; a transmission portion 4 at least partially disposed in the cavity, including a first transmission member 41 and a second transmission member 42, wherein: the first transmission member 41 is configured to rotate with The cleaning part 3 cooperates and is driven by the power source 16 to vibrate the cleaning part 3, thereby driving the first cleaning unit 31 and the second cleaning unit 32 of the cleaning part 3 to vibrate; the second transmission member 42 cooperates with the support member 2, and extends along the first axis. One end of the second transmission member 42 is constructed to cooperate with the first transmission member 41, and the other end is constructed to eccentrically cooperate with the second cleaning unit 32; when the first transmission member 41 is driven by the power source 16, it also drives one end of the second transmission member 42 to swing, and the second transmission member 42 uses the support member 2 as a fulcrum so that the other end drives the second cleaning unit 32 to rotate.

[0064] Specifically, the brush head body 1 extends along a first axis and comprises an open cavity defined by side walls, so that the brush head can be securely mounted on the handheld portion 13 and provides the necessary space for the internal transmission portion 4.

[0065] At one end of the brush head body 1, a cleaning part 3 is attached. The cleaning part 3 can pivot relative to the body and can adapt to the shape of the teeth and gums more flexibly, thereby achieving more effective cleaning. The cleaning part 3 includes two independent cleaning units, namely a first cleaning unit 31 and a second cleaning unit 32, wherein the second cleaning unit 32 is pivotable. In this way, the cleaning part 3 can not only achieve regional cleaning, but also perform different cleaning modes according to the characteristics of different tooth areas. For example, one unit can target the tooth surface, and the other unit is specifically used to clean hard-to-reach areas such as the gaps between teeth and the gingival sulcus, ensuring that the cleaning process is both efficient and comprehensive.

[0066] The transmission part 4 is at least partially arranged in the cavity of the brush head body 1, and includes a first transmission member 41 and a second transmission member 42. Driven by the power source 16, the first transmission member 41 drives the first cleaning unit 31 and the second cleaning unit 32 of the cleaning part 3 to vibrate back and forth, thereby effectively removing dental plaque and food residues on the surface of the teeth. The second transmission member 42 is arranged along the extension direction of the first axis and cooperates with the support member 2. One end of the second transmission member 42 cooperates with the first transmission member 41, and the other end cooperates eccentrically with the second cleaning unit 32. When the first transmission member 41 is driven by the power source 16, it not only drives the first cleaning unit 31 and the second cleaning unit 32 to vibrate back and forth, but also indirectly drives the second cleaning unit 32 to rotate back and forth through the swing of one end of the second transmission member 42.

[0067] During the cleaning process, when the user turns on the toothbrush, the power source 16 begins operating, applying force to the first transmission member 41 and driving the first cleaning unit 31 and the second cleaning unit 32 to rapidly reciprocate. This vibration not only effectively removes plaque and food debris from the tooth surface, but also helps soften and disperse residual matter between the teeth. Simultaneously, the second transmission member 42 swings in sync with the movement of the first transmission member 41, with one end of its swing engaging the first transmission member 41 and the other end eccentrically engaging the second cleaning unit 32. A support member 2 is provided on the sidewall of the brush head body 1. When the second transmission member 42 swings, it uses the support member 2 as a fulcrum, enabling the second cleaning unit 32 to perform reciprocating cleaning. For example, when the first transmission member 41 rotates in a first direction, it drives one end of the second transmission member 42 to swing in the first direction. Since the support member, which serves as the fulcrum, is fixed, the other end of the second transmission member 42 swings in the second direction, thereby driving the second cleaning unit 32 to rotate in the second direction. This rotary motion penetrates deep into the spaces between teeth and into the gum sulcus, effectively cleaning plaque and debris from these hard-to-reach areas.

[0068] Furthermore, in this embodiment, the rotational motion of the second cleaning unit 32 is not limited to simple circular motion. By adjusting the eccentric position and swing amplitude of the second transmission member 42, a more complex rotational trajectory can be achieved, better adapting to the shape of the teeth and gums, ensuring that every corner is thoroughly cleaned. The pivoting nature of the cleaning section 3 further enhances cleaning flexibility, allowing the brush head to be appropriately adjusted to the specific shape and arrangement of the teeth, thereby achieving optimal cleaning results.

[0069] The disclosed brush head significantly improves oral hygiene, particularly in the complex area between teeth and gums, achieving efficient and comprehensive cleaning. This not only helps users more effectively remove plaque and reduce tartar formation, but also reduces the risk of gingivitis and periodontitis, thereby maintaining good oral health. Furthermore, due to its highly effective cleaning method, it also promotes gum health and prevents tooth loosening and loss.

[0070] like Figure 1 、 Figures 3 to 6 As shown, in one embodiment of the present disclosure, when one end of the second transmission member 42 swings, the other end thereof swings in the opposite direction with the support member 2 as a fulcrum, thereby driving the second cleaning unit 32 to rotate.

[0071] Specifically, when the first transmission member 41 is driven by the power source 16 to begin vibrating, it not only drives the first cleaning unit 31 and the second cleaning unit 32 to vibrate back and forth, but also drives one end of the second transmission member 42 connected thereto to swing. At this time, the second transmission member 42 uses the portion in contact with the support member 2 as a fulcrum, allowing the other end to swing in a direction opposite to the swinging direction of the first end of the second transmission member 42. The fulcrum of the support member 2 ensures that the second transmission member 42 can swing stably.

[0072] Due to the eccentric cooperation between the second cleaning unit 32 and the second transmission member 42, the second cleaning unit 32 can rotate around its own axis, effectively cleaning hard-to-reach areas such as the gaps between teeth and the gingival sulcus, especially in the triangular area (gingival sulcus) adjacent to the teeth and gums, to achieve more in-depth and detailed cleaning.

[0073] like Figure 1 , Figures 4 to 6 As shown, in one embodiment of the present disclosure, along the extension direction of the first axis, the cavity is divided into a first cavity 51 and a second cavity 52 by the support member 2, and a limiting hole 21 is formed on the support member 2: the second transmission member 42 is constructed to extend from the first cavity 51 to the second cavity 52, and pass through the limiting hole 21, and extend from the second cavity 52 to eccentrically cooperate with the second cleaning unit 32.

[0074] Specifically, the cavity of the brush head body 1 is divided into a first cavity 51 and a second cavity 52 by the support member 2 along the extension direction of the first axis. The space in the cavity provides a movement space for the transmission part 4. The first transmission member 41 mainly rotates back and forth in the first cavity 51. The second transmission member 42 extends in the first cavity 51 and passes through the limiting hole 21 on the support member 2 to enter the second cavity 52 and eccentrically cooperate with the second cleaning unit 32. When the first transmission member 41 is driven by the power source 16, it not only drives the first cleaning unit 31 to vibrate back and forth, but also indirectly drives the second cleaning unit 32 to rotate by swinging one end of the second transmission member 42. When one end of the second transmission member 42 swings in the first cavity 51, it uses the support member 2 as a fulcrum, and the other end swings in the opposite direction in the second cavity 52, thereby driving the second cleaning unit 32 to rotate. A limiting hole 21 is provided on the support member 2. In this embodiment, the limiting hole 21 can be composed of cylindrical structures symmetrically arranged on both sides of the first transmission member 41. When one end of the second transmission member 42 starts to swing, the second transmission member 42 contacts the cylindrical structure on one side. Under the action of the cylindrical structure, the other end of the second transmission member 42 swings in the opposite direction. The limiting hole 21 is used to limit the motion trajectory of the second transmission member 42 to ensure that it can swing along a predetermined path and can cooperate with the second cleaning unit 32.

[0075] like Figures 1 to 3 As shown, in one embodiment of the present disclosure, the first transmission member 41 is also constructed to have a power transmission part 6 that cooperates with one end of the second transmission member 42: when the first transmission member 41 is driven by the power source 16, it rotates back and forth with the first axis as the rotation center, and the power transmission part 6 drives one end of the second transmission member 42 to swing back and forth; when one end of the second transmission member 42 swings back and forth, the other end of the second transmission member 42 swings back and forth with the support member 2 as the fulcrum, thereby driving the second cleaning unit 32 to rotate back and forth.

[0076] Specifically, when the first transmission member 41 is driven by the power source 16, it reciprocates about the first axis. A power transmission unit 6 is provided on the first transmission member 41, mating with one end of the second transmission member 42. As the first transmission member 41 reciprocates, the power transmission unit 6 rotates synchronously with the first transmission member 41, following the direction of rotation of the first transmission member 41. The power transmission unit 6 can be integrally formed with the first transmission member 41 or assembled thereto, depending on actual needs.

[0077] At the same time, the power transmission unit 6 engages one end of the second transmission member 42, causing it to also begin to oscillate back and forth. With the support member 2 as the fulcrum, the other end of the second transmission member 42 oscillates back and forth in the opposite direction, thereby driving the second cleaning unit 32 to rotate back and forth about its own axis. This design effectively cleans hard-to-reach areas such as the spaces between teeth and the gingival sulcus, particularly the triangular area between the teeth and gums (the gingival sulcus). This allows for a more in-depth and detailed cleaning.

[0078] like Figures 1 to 2 As shown, in one embodiment of the present disclosure, the power transmission portion 6 has a fitting hole 61 , and the second transmission member 42 is configured to be within the first cavity 51 , with one end at least partially passing through the fitting hole 61 .

[0079] Specifically, when the first transmission member 41 is driven by the power source 16, the power transmission unit 6 rotates back and forth about the first axis as the first transmission member 41 rotates. To ensure that the second transmission member 42 can work in conjunction with the first transmission member 41, a mating hole 61 is provided in the power transmission unit 6. The mating hole 61 is used to accommodate the second transmission member 42. The diameter of the mating hole 61 is larger than the circumferential dimension of the portion of the second transmission member 42 that enters the mating hole 61, thereby allowing the second transmission member 42 to mate with the first transmission member 41 more stably and flexibly. When the power transmission unit 6 begins to reciprocate with the first transmission member 41, one end of the second transmission member 42 will also swing back and forth within the mating hole 61 as the power transmission unit 6 moves.

[0080] like Figures 1 to 3 As shown, in one embodiment of the present disclosure, when the first transmission member 41 is driven by the power source 16, it rotates back and forth with the first axis as the rotation center, and the power transmission part 6 drives one end of the second transmission member 42 to swing back and forth, so that one end of the second transmission member 42 is relatively displaced relative to the matching hole 61 along the extension direction of the first axis.

[0081] Specifically, when the first transmission member 41 is driven by the power source 16, the power transmission unit 6 rotates back and forth about the first axis. Simultaneously, the power transmission unit 6 is connected to one end of the second transmission member 42, driving the second transmission member 42 to oscillate back and forth. The position at which the second transmission member 42 contacts the power transmission unit 6 determines the amplitude and frequency of the oscillation.

[0082] When one end of the second transmission member 42 swings back and forth, since it at least partially passes through the matching hole 61 on the power transmission component, it will be relatively displaced relative to the matching hole 61 along the extension direction of the first axis. When one end of the second transmission member 42 swings to one side, its position relative to the matching hole 61 will move accordingly; when it swings in the opposite direction, its position will also change accordingly.

[0083] like Figure 1 As shown, in one embodiment of the present disclosure, along the extension direction of the first axis, the support member 2 is located between the second cleaning unit 32 and the power transmission part 6, and the support member 2 is located between the other end of the second transmission member 42 and the power transmission part 6.

[0084] Specifically, the support member 2 serves as a fulcrum, and the movement of the second transmission member 42 is achieved through the principle of leverage. One end of the second transmission member 42 is connected to the power transmission part 6. When one end of the second transmission member 42 is acted upon by the driving force and begins to swing, the second transmission member 42 rotates around the fixed fulcrum of the support member 2, so that the other end of the second transmission member 42 can use this fulcrum to swing in the opposite direction, driving the second cleaning unit 32 connected to the other end of the second transmission member 42. The force applied to one end of the second transmission member 42 causes the other end to swing in the opposite direction. This swinging not only achieves the transmission of force, but also amplifies the effect of the force due to the lever effect, allowing the second cleaning unit 32 to perform efficient reciprocating rotation, thereby achieving the cleaning function and improving cleaning efficiency.

[0085] like Figures 1 to 3 As shown, in one embodiment of the present disclosure, along the extension direction of the first axis, the support member 2 is located between one end and the other end of the second transmission member 42.

[0086] Specifically, the support member 2 is located between the two ends of the second transmission member 42, serving as a fulcrum for the movement of the second transmission member 42. When one end of the second transmission member 42 periodically swings under the propulsion of the power transmission unit 6, the support member 2 ensures the stability of the movement of the second transmission member 42. Due to the action of the support member 2, the other end of the second transmission member 42 correspondingly swings in the opposite direction, thereby driving the second cleaning unit 32 to perform corresponding reciprocating rotational motion.

[0087] like Figure 1 As shown, in one embodiment of the present disclosure, the cleaning portion 3 further includes an assembly part 7 , the first cleaning unit 31 and the second cleaning unit 32 are both disposed on the assembly part 7 , and the assembly part 7 is attached to one end of the brush head body 1 .

[0088] Specifically, assembly 7 is attached to one end of the brush head body 1 and houses the first cleaning unit 31 and the second cleaning unit 32, ensuring convenient positioning and operation of the first and second cleaning units 31, 32. When one end of the second transmission member 42 receives power from the first transmission member 41 and begins to swing, the second cleaning unit 32 reciprocates along a predetermined trajectory. Flexible adjustment of assembly 7 allows for adaptability to varying cleaning needs and oral structures, achieving more precise and comprehensive cleaning results.

[0089] like Figure 1As shown, in one embodiment of the present disclosure, the second cleaning unit 32 has a first side and a second side relative to each other, and a brush filament 8 extends from the first side: a pivot member 9 is formed on the second side, and the pivot member 9 and the assembly member 7 can be pivotally matched; and / or: a first engaging member is formed on the second side, and a second engaging member is formed at the corresponding position of the assembly member 7, and the first engaging member and the second engaging member are engaged and connected.

[0090] Specifically, the second cleaning unit 32 has a first side surface and a second side surface that are opposite to each other. Brush filaments 8 extend from the first side surface, and these brush filaments 8 are used to directly clean the teeth. A pivot member 9 is provided on the second side surface, and the pivot member 9 is pivotally matched with the assembly 7. In this embodiment, the pivot member 9 can be set as a rotating shaft or other rotatable components, and the second cleaning unit 32 can perform reciprocating rotation around the rotating shaft relative to the assembly 7, thereby achieving a more efficient cleaning action. A first engaging member is also provided on the second side surface, and a second engaging member is formed at a corresponding position of the assembly 7, and the first engaging member and the second engaging member are fixed together by a snap connection, which can ensure that the second cleaning unit 32 can be firmly mounted on the assembly 7, and it is also convenient for the user to disassemble and replace the second cleaning unit 32.

[0091] like Figure 1 and Figure 3 As shown, in one embodiment of the present disclosure, a driving member 10 eccentrically matched with the second cleaning unit 32 is formed at the other end of the second transmission member 42, and a coupling member 11 is formed corresponding to the second side surface deviating from the center position of the side surface. The driving member 10 cooperates with the coupling member 11. When one end of the second transmission member 42 swings, the second transmission member 42 uses the support member 2 as a fulcrum to enable the driving member 10 to drive the second cleaning unit 32 to rotate.

[0092] A driving member 10 is formed at a first end of the second transmission member 42 and is used to eccentrically engage with the second cleaning unit 32. A coupling member 11 is formed on a second side surface of the second cleaning unit 32, corresponding to a position offset from the side surface center. The driving member 10 engages with the coupling member 11. When one end of the second transmission member 42 swings, the second transmission member 42 uses the support member 2 as a fulcrum, so that the driving member 10 drives the second cleaning unit 32 to rotate.

[0093] Specifically, when the first transmission member 41 is driven by the power source 16, the power transmission unit 6 begins to reciprocate about the first axis. Simultaneously, the power transmission unit 6 engages with one end of the second transmission member 42, causing the second end of the second transmission member 42 to also begin to swing back and forth. A driving member 10 is formed at the other end of the second transmission member 42. A coupling member 11 is formed on the second side of the second cleaning unit 32, offset from the center of the side, and the driving member 10 engages with the coupling member 11. When one end of the second transmission member 42 swings, the second transmission member 42 uses the support member 2 as a fulcrum, causing the driving member 10 to drive the second cleaning unit 32 to rotate.

[0094] like Figure 1 As shown, in one embodiment of the present disclosure, the driving member 10 is a bending member.

[0095] Specifically, a bending-type component is provided at one end of the second transmission member 42, and the bending-type component is eccentrically matched with the second cleaning unit 32. A coupling member 11 is formed corresponding to the second side surface of the second cleaning unit 32, which deviates from the center position of the side surface, and the bending-type component is matched with the coupling member 11. When one end of the second transmission member 42 swings, the second transmission member 42 uses the support member 2 as a fulcrum, so that the bending-type component drives the second cleaning unit 32 to rotate. The bending-type component can effectively convert the linear reciprocating swing of the second transmission member 42 into the rotational motion of the second cleaning unit 32, which helps to improve the cleaning efficiency. In addition, the eccentric matching design of the bending-type component and the coupling member 11 enables the second cleaning unit 32 to achieve a larger rotation in a smaller space, which is beneficial for deep cleaning of the gaps between teeth.

[0096] like Figure 2 As shown, in one embodiment of the present disclosure, a snap-fit ​​structure 71 is provided on the assembly part 7, which is snap-fitted with a first snap-fit ​​groove 72 provided on the brush head body 1; or a first snap-fit ​​groove 72 is provided on the assembly part 7, which is snap-fitted with the snap-fit ​​structure 71 provided on the brush head body 1.

[0097] Specifically, to ensure that the assembly part 7 can be securely mounted on the brush head body 1, a snap-fit ​​structure 71 can be provided on the assembly part 7, and a first snap-fit ​​groove 72 can be provided on the brush head body 1. The snap-fit ​​structure 71 cooperates with the first snap-fit ​​groove 72, thereby enabling the assembly part 7 to be snap-fitted to the brush head body 1. Alternatively, the first snap-fit ​​groove 72 can be provided on the assembly part 7, and the snap-fit ​​structure 71 can be provided on the brush head body 1. Similarly, the snap-fit ​​structure 71 cooperates with the first snap-fit ​​groove 72 to achieve installation of the assembly part 7. This design of the snap-fit ​​structure 71 not only ensures that the assembly part 7 can be securely mounted on the brush head body 1, but also makes the assembly part 7 easy to remove and replace.

[0098] like Figure 2As shown, in one embodiment of the present disclosure, along the circumference of the first axis, the size of the first slot 72 is larger than the clamping structure 71, so that the assembly part 7 can reciprocate relative to the brush head body 1 along the circumference of the first axis.

[0099] Specifically, the power source 16 cooperates with the assembly 7, driving it to reciprocate. This causes the assembly 7 to rotate relative to the brush head body 1, vibrating back and forth, thereby driving the first cleaning unit 31 and the second cleaning unit 32 to vibrate back and forth. Therefore, along the circumferential direction of the first axis, the first retaining groove 72 is larger than the retaining structure 71, allowing the assembly 7 to rotate relative to the brush head body 1 along the circumferential direction of the first axis. This ensures that the assembly 7 can remain fixed to the brush head body 1 while also vibrating back and forth to a certain extent according to cleaning needs, adapting to the shape of the teeth and gums and improving cleaning efficiency.

[0100] like Figures 1 to 3 As shown, in one embodiment of the present disclosure, the brush head also includes a fixing part 12 arranged in the cavity, and the fixing part 12 cooperates with the handheld part 13 with a built-in power source 16. When the power source 16 drives the first transmission part 41, the brush head body 1 and the handheld part 13 do not rotate relative to each other.

[0101] Specifically, to ensure that the brush head body 1 can stably maintain its relative position with the handheld portion 13 during the cleaning process, the brush head also includes a fixing member 12 disposed in the brush head cavity. This fixing member 12 is used to cooperate with the handheld portion 13, which has a built-in power source 16. When the power source 16 is operating to drive the first transmission member 41, the fixing member 12 ensures that the brush head body 1 and the handheld portion 13 do not rotate relative to each other. Even when the first transmission member 41 and the second transmission member 42 drive the cleaning unit to perform complex movements, the brush head body 1 can remain stable and will not produce unnecessary rotation due to power transmission, thereby ensuring a smoother and more efficient cleaning process.

[0102] like Figures 1 to 3 As shown, in one embodiment of the present disclosure, along the extension direction of the first axis, one end of the first transmission member 41 is tightly fitted with the assembly part 7. When the power source 16 drives the first transmission member 41, the first transmission member 41 drives the assembly part 7 to drive the first cleaning unit 31 and the second cleaning unit 32 to vibrate back and forth.

[0103] Specifically, in the extension direction along the first axis, one end of the first transmission member 41 is tightly fitted with the assembly 7. When the power source 16 drives the first transmission member 41, the first transmission member 41 rotates back and forth with the first axis as the rotation center, and drives the first cleaning unit 31 and the second cleaning unit 32 to perform corresponding reciprocating rotation by driving the assembly 7.

[0104] like Figures 1 to 3As shown, in one embodiment of the present disclosure, along the extension direction of the first axis, the other end of the first transmission member 41 cooperates with the fixing member 12.

[0105] Specifically, in the extension direction along the first axis, the other end of the first transmission member 41 cooperates with the fixing member 12 provided in the inner cavity of the brush head. When the power source 16 drives the first transmission member 41, the first transmission member 41 rotates back and forth with the first axis as the rotation center. This reciprocating rotation not only drives the assembly 7 to vibrate back and forth, but also drives the first cleaning unit 31 and the second cleaning unit 32 to perform corresponding reciprocating vibrations or rotations through the assembly 7. At the same time, the fixing member 12 ensures that the brush head body 1 and the handheld part 13 do not move relative to each other. Even when the first transmission member 41 and the second transmission member 42 drive the cleaning units to perform complex movements, the brush head body 1 can remain stable and will not produce unnecessary rotation due to power transmission, thereby ensuring that the entire cleaning process is smoother and more efficient.

[0106] like Figure 1 As shown, in one embodiment of the present disclosure, the first transmission member 41 is formed with a support member 14 that is at least partially in contact with the side wall.

[0107] Specifically, to ensure more uniform reciprocating rotation of the first transmission member 41, a support member 14 is formed on the first transmission member 41, at least partially contacting the sidewall. This ensures smoother movement of the first transmission member 41 under the drive of the power source 16, thereby reducing vibration and noise and improving the efficiency of the entire cleaning system. The contact between the support member 14 and the sidewall helps offset the unbalanced torque generated by the rotation of the first transmission member 41, ensuring relative balance of the first transmission member 41 and improving the stability and efficiency of the entire cleaning system.

[0108] like Figure 3 As shown, in the second aspect of the present disclosure, the present disclosure provides a toothbrush, comprising: a handheld portion 13, the handheld portion 13 is constructed for holding; according to the brush head as described above, the brush head is constructed to be mounted on the handheld portion 13, and the cleaning portion 3 of the brush head is constructed to vibrate relative to the handheld portion 13.

[0109] Specifically, the toothbrush comprises a handheld portion 13 and a brush head. The user grasps the handheld portion 13, and the brush head is mounted on the handheld portion 13 to clean the teeth. The cleaning portion 3 of the brush head vibrates relative to the handheld portion 13. This vibration includes not only the reciprocating vibration of the first cleaning unit 31 but also the reciprocating rotation of the second cleaning unit 32. This design ensures that the toothbrush effectively removes plaque and food debris from the tooth surface, while also reaching hard-to-reach areas such as the gaps between teeth and the gingival sulcus, achieving comprehensive and efficient cleaning of the teeth.

[0110] like Figure 3As shown, in one embodiment of the present disclosure, a power source 16 is provided in the handheld portion 13. When the power source 16 drives the first transmission member 41, the brush head body 1 and the handheld portion 13 do not rotate relative to each other.

[0111] Specifically, a power source 16 is disposed within the handheld portion 13. When the power source 16 is operating to drive the first transmission member 41, the brush head body 1 and the handheld portion 13 do not rotate relative to each other. This allows the brush head body 1 to remain stable even when the first and second transmission members 41, 42 drive the cleaning unit to perform complex movements, preventing unnecessary rotation due to power transmission. This ensures a smoother and more efficient cleaning process.

[0112] like Figures 1 to 3 As shown, in one embodiment of the present disclosure, the handheld portion 13 cooperates with the fixing member 12, the fixing member 12 is constructed to have a hollow cavity 15 connected to the first transmission member 41, and the power source 16 is constructed to pass through the hollow cavity 15 and connect to the first transmission member 41 so that the brush head is engaged with the handheld portion 13.

[0113] Specifically, the handheld portion 13 cooperates with the fixed member 12, which has a hollow cavity 15 that communicates with the first transmission member 41. A power source 16 passes through the hollow cavity 15 and connects to the first transmission member 41, thereby engaging the brush head with the handheld portion 13. When the power source 16 is in operation, power is effectively transmitted through the hollow cavity 15 of the fixed member 12 to the first transmission member 41, thereby driving the first cleaning unit 31 and the second cleaning unit 32 to perform cleaning operations. This ensures a stable connection between the brush head and the handheld portion 13 and ensures efficient power transmission.

[0114] The brush head provided by the present disclosure can effectively remove dental plaque and food debris through the vibration of the first cleaning unit and the rotation of the second cleaning unit, reducing the formation of dental calculus and thereby reducing the risk of gingivitis and periodontitis. In addition, the pivotable nature of the cleaning unit can adapt to the oral structure of different users, especially for hard-to-reach areas such as the gingival sulcus, so that the brush head can better fit the tooth surface and gum line, thereby achieving more comprehensive and thorough cleaning. Not only does it improve cleaning efficiency, it can also promote the user's oral health. Long-term use can help prevent problems such as loose teeth and tooth loss.

[0115] The toothbrush provided by this disclosure, through the combination of a handheld portion and a brush head, can effectively clean the complex areas adjacent to teeth and gums, particularly hard-to-reach areas such as the gingival sulcus. The cleaning portion of the brush head can vibrate relative to the handheld portion, which not only enhances plaque removal but also penetrates deep into the gaps between teeth and the gingival sulcus to remove stubborn stains and bacteria, significantly reducing the risk of periodontal disease. Furthermore, it can reduce tartar formation, protect gum health, avoid gingivitis and periodontitis, and prevent tooth loosening and loss, thereby improving the efficiency and quality of oral cleaning.
