Description

Technical Field

[0001] The present application relates to the field of cleaning technology, and more specifically, to a toothbrush head and an electric toothbrush. Background Art

[0002] An electric toothbrush is an electronic device that can clean the oral cavity. When the electric toothbrush is in operation, the brush handle drives the toothbrush head to vibrate to clean the surface and gaps of the teeth. The brush plate of current electric toothbrushes is mostly a whole without gaps, so the vibration transmission effect of the brush plate to the bristles arranged thereon is also the same. Since the tooth surface to be cleaned has many unevenness, the whole brush plate cannot transmit different vibration amplitudes to different fitting positions of the bristles, and the cleaning effect is poor. Utility Model Content

[0003] The embodiments of the present application provide a toothbrush head and an electric toothbrush, which are at least used to solve the problem of poor cleaning effect of electric toothbrushes.

[0004] The toothbrush head of the embodiment of the present application includes bristles, a plurality of implanted hair parts, a connecting part and a supporting part. The plurality of implanted hair parts are spaced apart from each other, and the implanted hair parts include a first side and a second side opposite to each other in the thickness direction of the toothbrush head. The implanted hair parts are also provided with implanted hair holes, and the bristles are arranged in the implanted hair holes and extend from the first side of the implanted hair parts. The connecting part is arranged between adjacent implanted hair parts and is used to connect adjacent implanted hair parts. The supporting part is arranged on the second side of the implanted hair parts, and the supporting part is connected to at least the implanted hair parts; when the implanted hair parts are subjected to force, the connecting part is deformed.

[0005] During the use of the toothbrush head, the bristles will be subjected to pressure from the part to be cared for (i.e., structures in the oral cavity such as teeth), and the bristles will transmit external force to the hair-implanted part, so that the connecting part connected to the hair-implanted part is deformed by force. When the connecting part is deformed by force, adjacent hair-implanted parts will move away from or approach each other, so that the distance between adjacent hair-implanted parts changes. At this time, the bristles arranged on the hair-implanted part will fit on the surface of the teeth in contact with it and in the gaps between the teeth. Therefore, when the toothbrush head vibrates, the vibrating bristles clean the surface of the teeth and the gaps between the teeth more fully, and the cleaning effect is better.

[0006] In some embodiments, the hair implantation portion includes a first hair implantation portion and a second hair implantation portion, the first hair implantation portion is connected to the support portion, the second hair implantation portion is spaced apart from the support portion, and the first hair implantation portion and the second hair implantation portion are connected via the connection portion.

[0007] The first hair implantation part and the second hair implantation part are connected to each other through a connecting part, and there is a gap between the first hair implantation part and the second hair implantation part. The first hair implantation part can be connected to the supporting part, and the second hair implantation part is spaced from the supporting part. When the bristles are subjected to force and the connecting part is deformed, the second hair implantation part can move relative to the first hair implantation part to increase the distance between the first hair implantation part and the second hair implantation part. At this time, the toothbrush head will be deformed, and the bristles arranged on the first hair implantation part and the second hair implantation part will shift to contact different positions of the part to be cared for, so as to achieve cleaning of various positions of the part to be cared for.

[0008] In some embodiments, in the length direction of the toothbrush head, the second hair-planting portion includes at least two, and the first hair-planting portion is disposed between the at least two second hair-planting portions.

[0009] In the case where the first hair-planting portion is arranged between at least two second hair-planting portions, the at least two second hair-planting portions can be arranged along the length direction of the toothbrush head or along the width direction of the toothbrush head. The first hair-planting portion is located in the middle of the toothbrush head (along the length direction of the toothbrush head and / or along the width direction of the toothbrush head) and is connected to the support portion. When the bristles are subjected to force and the connecting portion is deformed, at least two second hair-planting portions can move in various directions away from the first hair-planting portion with the first hair-planting portion as the center, so that the bristles arranged on the first hair-planting portion and the at least two second hair-planting portions can contact different positions of the portion to be cared for.

[0010] In some embodiments, in the length direction of the toothbrush head, the first hair-planting parts include at least two, and the support parts include at least two. At least two of the support parts are respectively connected to at least two of the first hair-planting parts, and the second hair-planting part is arranged on any side of the center line of at least two of the support parts in the width direction of the toothbrush head.

[0011] The first hair-planting portion can correspond to the supporting portion, and when the first hair-planting portion includes at least two, each first hair-planting portion can be connected to the supporting portion. At this time, at least two first hair-planting portions can be arranged along the length direction of the toothbrush head, and there is still at least one first hair-planting portion arranged in the middle of the toothbrush head (along the length direction of the toothbrush head and / or along the width direction of the toothbrush head). The center line of at least two supporting portions passes through the first hair-planting portion arranged in the middle of the toothbrush head, and at this time, the second hair-planting portion can be arranged on any side of the center line of at least two supporting portions along the width direction of the toothbrush head. In the case where the second hair-planting portion includes two, the two second hair-planting portions can be arranged on both sides of the center line of at least two supporting portions along the width direction of the toothbrush head.

[0012] In some embodiments, the support portion is also at least partially connected to the connection portion connected to the second hair-implanted portion.

[0013] When the support part is connected to the connecting part, when the connecting part is deformed, the support part can support the side of the connecting part away from the bristles to improve the strength of the connecting part and avoid the connection part from breaking. In addition, when the support part is connected to the connecting part and the bristle-planting part at the same time, the contact area between the support part, the connecting part and the bristle-planting part is large, the connection between the three is stable, and the toothbrush head is not easily damaged.

[0014] In some embodiments, the toothbrush head includes a first area and a second area arranged around the first area, the hair-planting portion in the first area is connected to the supporting portion to form a rigid support, and the hair-planting portion in the second area is connected to the hair-planting portion in the first area via the connecting portion to form a soft support.

[0015] The first area refers to the partial area where the hair-planting part is directly connected to the support part. When the hair-planting part in the first area is subjected to force, the support part connected to the hair-planting part can support the hair-planting part, so that the hair-planting part in the first area will not shake or swing relative to the support part after being subjected to force, and the connection between the hair-planting part and the support part is more stable. The second area refers to the partial area where the hair-planting part is not directly connected to the support part. The hair-planting part located in the second area can only be connected to the hair-planting part in the first area through the connecting part. Therefore, when the hair-planting part in the second area is subjected to force, the connecting part is deformed by the force, and the hair-planting part in the second area will tilt, shake or swing relative to the hair-planting part in the first area, so that part of the toothbrush head is deformed.

[0016] In certain embodiments, along the thickness direction of the toothbrush head, adjacent hair-implanting portions are spaced apart, and the thickness of the connecting portion is smaller than the thickness of the hair-implanting portion.

[0017] When the thickness of the connecting portion is less than that of the implanted hair portion, the connecting portion is more likely to deform under stress than the implanted hair portion. When adjacent implanted hair portions are spaced apart from each other, the implanted hair portions can move closer to each other and / or farther away from each other when the connecting portion is deformed under stress, so that the bristles on the implanted hair portion move to different positions, thereby improving the cleaning effect of the toothbrush head.

[0018] In some embodiments, along the thickness direction of the toothbrush head, a surface of the connecting portion facing the supporting portion is flush with a surface where the second side of the hair implanting portion is located.

[0019] When the surface of the connection part facing the support part is flush with the surface of the second side of the hair-planting part, the side of the connection part facing the bristles is located in the gap between adjacent hair-planting parts. When the bristles are subjected to force, the bristles will transfer the force to the hair-planting part. At this time, the hair-planting part can only push the connection part to bend to the side away from the bristles, but not to the side close to the bristles. The bristles can better wrap the care part and the cleaning effect is better.

[0020] In some embodiments, the hair implanting portion, the connecting portion and the supporting portion are an integrally formed structure.

[0021] The one-piece molded hair-planting part, connecting part and supporting part can form a stable connection. On the one hand, it can avoid the gaps in the connections between the hair-planting part, connecting part and supporting part that lead to dirt deposition. On the other hand, it can also avoid the separation of the connections between the hair-planting part, connecting part and supporting part when subjected to force, leading to damage to the toothbrush head, thereby extending the service life of the toothbrush head.

[0022] In some embodiments, the toothbrush head further comprises a deformation portion that can be deformed under force, and the deformation portion is combined with at least one of the hair implantation portion, the connection portion and the support portion to support and / or protect the portion combined with the deformation portion.

[0023] The deformable part is made of a flexible material such as soft glue. The deformable part can be used to wrap the hair-planting part to prevent collision between the hair-planting part and the part to be cared for. The two opposite sides of the connecting part along the thickness direction of the toothbrush head will face the gap between the hair-planting parts. The deformable part used for protection and filling can fill the gap between the hair-planting parts and wrap the opposite sides of the connecting part to protect the connecting part and prevent it from breaking.

[0024] In some embodiments, the hair implanting portion also includes a peripheral side portion respectively connected to the first side of the hair implanting portion and the second side of the hair implanting portion, the deformation portion wraps the second side of the hair implanting portion and at least a portion of the peripheral side portion of the hair implanting portion, and the top of the hair implanting portion protrudes from the deformation portion; the deformation portion is also used to fill the gap between adjacent hair implanting portions.

[0025] The deformation part is a soft rubber structure, which can fill the gap between the hair-planting parts and cover the second side and the peripheral side of the hair-planting part. Therefore, the deformation part is not easy to fall off from the hair-planting part, and there is no obvious boundary between the deformation part and the hair-planting part, so it is not easy to form dirt deposition. The deformation part can be formed on the hair-planting part and other structures by hot-melting the soft rubber material and then solidifying it again. When the first surface is protruding compared to the deformation part, the soft rubber material in a fluid state will not enter the hair-planting holes provided on the first side of the hair-planting part, thereby preventing the bristles from being difficult to install in the hair-planting holes.

[0026] In some embodiments, the hair implanting portion includes a plurality of hair implanting sheets, each of which is provided with the hair implanting holes, and gaps are formed between adjacent hair implanting sheets. The deformation portion is used to wrap the bottom and side walls of each of the hair implanting sheets and fill the gaps between adjacent hair implanting sheets.

[0027] The hair-planting sheet is a structure for connecting with the bristles, and each hair-planting sheet corresponds to a hair-planting hole and the bristles arranged in the hair-planting hole. Multiple hair-planting sheets spaced apart from each other can form a hair-planting section together. The deformation section can fill the gaps between multiple hair-planting sections, and can also fill the gaps between multiple hair-planting sheets in each hair-planting section, so that each hair-planting sheet is connected to the deformation section. Avoid the uneven surface of the toothbrush head, which causes dirt residue and affects the use.

[0028] Along the thickness direction of the toothbrush head, the thickness of the connecting portion is smaller than the thickness of the hair-implanting portion, so that the deformation portion is filled between adjacent hair-implanting portions and covers the connecting portion.

[0029] When the thickness of the connecting portion is less than that of the hair-planting portion, the connecting portion is more easily deformed under stress than the hair-planting portion. When adjacent hair-planting portions are spaced apart from each other, the hair-planting portions can move closer to and / or farther away from each other when the connecting portion is deformed under stress, so that the bristles on the hair-planting portions move to different positions, thereby improving the cleaning effect of the toothbrush head. The two opposite sides of the connecting portion along the thickness direction of the toothbrush head will face the gap between the hair-planting portions, and the deformable portion used for protection and filling can fill the gap between the hair-planting portions and wrap the opposite sides of the connecting portion to protect the connecting portion and prevent the connecting portion from breaking.

[0030] In some embodiments, the toothbrush head also includes a mounting portion, which is connected to an end of the supporting portion away from the hair-implanted portion, and a gap is provided between the mounting portion and the hair-implanted portion. The toothbrush head also includes a deformation portion that can be deformed under force, and the deformation portion is used to wrap the bottom and sides of the mounting portion and / or fill the gap between the mounting portion and the hair-implanted portion.

[0031] The mounting part is a structure that can connect to the handle of the electric toothbrush and transmit vibrations. In the case where there is a gap between the mounting part and the hair-planting part, when the connection part is deformed and the size of the gap between adjacent hair-planting parts changes, the gap between the mounting part and the hair-planting part can provide space for the hair-planting part to move, so that the bristles on the hair-planting part can move relative to the mounting part. The deformable part used for protection and filling can fill the gap between the mounting part and the hair-planting part and support the connecting part to prevent the hair-planting part from being broken due to excessive force on the connecting part.

[0032] The electric toothbrush of the embodiment of the present application comprises the toothbrush head and the brush handle as described in any one of the above embodiments, and the toothbrush head is mounted on the brush handle.

[0033] The brush handle can vibrate and transmit the vibration to the bristles on the toothbrush head. When the toothbrush head is subjected to force, the connecting part will be deformed to change the distance between adjacent bristle parts. At this time, the bristles arranged on the bristle parts will fit on the surface of the teeth in contact with it and in the gaps between the teeth. Therefore, when the toothbrush head vibrates, the vibrating bristles clean the surface of the teeth and the gaps between the teeth more fully, and the cleaning effect is better.

[0049] See also Figures 1 to 3The toothbrush head 100 of the present application includes bristles 1101, a plurality of implanted hair portions 11, a connecting portion 13 and a supporting portion 15. The plurality of implanted hair portions 11 are spaced apart from each other, and the implanted hair portions 11 include a first side 101 and a second side 102 opposite to each other in the thickness direction Z of the toothbrush head 100. The implanted hair portions 11 are also provided with implanted hair holes 1111, and the bristles 1101 are arranged in the implanted hair holes 1111 and extend from the first side 101 of the implanted hair portions 11. The connecting portion 13 is arranged between adjacent implanted hair portions 11 and is used to connect adjacent implanted hair portions 11. The supporting portion 15 is arranged on the second side 102 of the implanted hair portions 11, and the supporting portion 15 is connected to at least the implanted hair portions 11; when the implanted hair portions 11 are subjected to force, the connecting portion 13 is deformed.

[0050] Among them, the implanting hole 1111 is an opening on the implanting part 11 for installing the bristles 1101. The implanting hole 1111 can be formed by penetrating the implanting part 11, or can be formed by being recessed from the first side 101 of the implanting part 11 to the second side 102 of the implanting part 11. The bristles 1101 are a structure for cleaning and / or caring for teeth, gums or the inner wall of the oral cavity waiting for care. Each bristle 1101 may include a plurality of brush filaments. The material of the bristles 1101 includes but is not limited to nylon, polyamide or silicone. When the material of the bristles 1101 is a hard material such as nylon or polyamide, the free end of the bristle 1101 can contact the tooth surface and clean the teeth and the gaps between the teeth. When the material of the bristles 1101 is a flexible material such as silicone, the free ends of the bristles 1101 can contact the tooth surface to perform polishing-like care on the tooth surface. In addition, the free ends of the bristles 1101 can also be used to clean easily damaged parts such as the gums or the inner walls of the mouth, so that the toothbrush head 100 has a better cleaning effect without causing damage to the user.

[0051] In the toothbrush head 100 of the present application, the bristles 1101 will be subjected to pressure from the part to be cared for (i.e., structures in the oral cavity such as teeth), and at this time, the bristles 1101 will transmit external force to the hair-implanted part 11, so that the connecting part 13 connected to the hair-implanted part 11 is deformed by force. When the connecting part 13 is deformed by force, adjacent hair-implanted parts 11 will move away from or approach each other, so that the distance between adjacent hair-implanted parts 11 changes. At this time, the bristles 1101 arranged on the hair-implanted part 11 will fit on the surface of the teeth in contact therewith and in the gaps between the teeth. Therefore, when the toothbrush head 100 vibrates, the vibrating bristles 1101 clean the surface of the teeth and the gaps between the teeth more fully, and the cleaning effect is better.

[0052] The toothbrush head 100 is further described below with reference to the accompanying drawings.

[0053] See also Figure 1 and Figure 3 , and combined with Figure 4In some embodiments, the toothbrush head 100 includes a brush body 10 and a rod body 30 connected to each other. The hair implantation portion 11, the connection portion 13 and the support portion 15 are all partial structures of the brush body 10. The rod body 30 is roughly a cylindrical structure, and the shape of the cross section of the rod body 30 includes but is not limited to a perfect circle, an ellipse or a polygon. The rod body 30 is connected to the brush body 10. In some embodiments, the rod body 30 and the brush body 10 are integrally formed. The materials of the rod body 30 and the brush body 10 can be the same or different, which is not limited here. In other embodiments, the rod body 30 and the brush body 10 are separately formed, and the rod body 30 and the brush body 10 can be connected by a non-detachable method such as gluing, hot melt connection or interference connection, or can be connected by a detachable method such as snap connection, threaded connection or bolt connection, which is not limited here. The length direction X of the toothbrush head 100 can be either the direction from the brush body 10 to the rod body 30 or the direction from the rod body 30 to the brush body 10. Along the length direction X of the toothbrush head 100, the brush body 10 includes a first end and a second end opposite to each other. The first end of the brush body 10 is away from the rod body 30, and the second end of the brush body 10 is close to the rod body 30. The width direction Y of the toothbrush head 100 is perpendicular to the length direction X of the toothbrush head 100. The thickness direction Z of the toothbrush head 100 is perpendicular to both the length direction X of the toothbrush head 100 and the width direction Y of the toothbrush head 100.

[0054] Further, in some embodiments, the hair-planting portion 11, the connecting portion 13 and the supporting portion 15 are separately formed structures, and the hair-planting portion 11, the connecting portion 13 and the supporting portion 15 can be fixed to each other by non-detachable means such as gluing, hot-melt connection or interference connection, or can be connected to each other by detachable means such as snap connection, threaded connection or bolt connection, and there is no limitation here. In other embodiments, the hair-planting portion 11, the connecting portion 13 and the supporting portion 15 are integrally formed structures. A stable connection can be formed between the integrally formed hair-planting portion 11, the connecting portion 13 and the supporting portion 15, which can avoid the presence of gaps at the connection between the hair-planting portion 11, the connecting portion 13 and the supporting portion 15, which may cause dirt deposition, and can also avoid the separation of the connection between the hair-planting portion 11, the connecting portion 13 and the supporting portion 15 when subjected to force, which may cause damage to the toothbrush head 100, thereby extending the service life of the toothbrush head 100.

[0055] Specifically, in some embodiments, the implanted hair portion 11 is a structure that can be connected to the bristles 1101. In some embodiments, the implanted hair portion 11 and the bristles 1101 are integrally formed. In other embodiments, the implanted hair portion 11 and the bristles 1101 are separately formed. One end of the bristles 1101 extends into the implanted hair portion 11 and is installed on the implanted hair portion 11, and the other end of the bristles 1101 is a free end located on the side where the first side 101 of the implanted hair portion 11 is located. The extension direction of the bristles 1101 can be parallel to the thickness direction Z of the toothbrush head 100, or can be inclined relative to the thickness direction Z of the toothbrush head 100, and there is no limitation here. There is a gap 104 between adjacent hair-planting parts 11, and the connecting part 13 is located in the gap 104 and is a structure capable of connecting at least two mutually spaced hair-planting parts 11. The connecting part 13 is generally a plate-like structure with a small thickness and is easily bent and deformed by force. When a user uses the toothbrush head 100, the user will apply external force to the bristles 1101. At this time, the bristles 1101 will be bent by pressure on the one hand, and on the other hand, the external force will be transmitted to the hair-planting part 11 connected to the bristles 1101. Since only the connecting part 13 is connected to each other between adjacent hair-planting parts 11, when the hair-planting parts 11 are subjected to force, the connecting part 13 will bend and deform along the thickness direction Z of the toothbrush head 100 under the action of external force. At this time, the size of the gap between adjacent hair-planting parts 11 will change, so that the brush body 10 will be deformed.

[0056] More specifically, please combine Figure 7 In some embodiments, the toothbrush head 100 may further include a first area 105 and a second area 106 arranged around the first area 105. The support portion 15 is a structure capable of supporting the hair-planting portion 11. The first area 105 refers to a partial area where the hair-planting portion 11 is directly connected to the support portion 15. The hair-planting portion 11 in the first area 105 is connected to the support portion 15 to form a rigid support. When the hair-planting portion 11 in the first area 105 is subjected to force, the support portion 15 connected to the hair-planting portion 11 can support the hair-planting portion 11, so that the hair-planting portion 11 in the first area 105 will not shake or swing relative to the support portion 15 after being subjected to force, and the connection between the hair-planting portion 11 and the support portion 15 is more stable. The second area 106 refers to a partial area where the hair-planting portion 11 is not directly connected to the support portion 15. The hair-planting portion 11 in the second area 106 is connected to the hair-planting portion 11 in the first area 105 via the connecting portion 13 to form a soft support. The hair-implanted portion 11 in the second area 106 can only be connected to the hair-implanted portion 11 in the first area 105 through the connecting portion 13. Therefore, when the hair-implanted portion 11 in the second area 106 is stressed, the connecting portion 13 is deformed by the stress, and the hair-implanted portion 11 in the second area 106 will tilt, shake or swing relative to the hair-implanted portion 11 in the first area 105, so that the toothbrush head 100 is partially deformed.

[0057] More specifically, please combine Figure 5 In some embodiments, the hair implanting portion 11 includes a plurality of hair implanting sheets 107. The hair implanting sheets 107 are structures for connecting with the bristles 1101. Each hair implanting sheet 107 is roughly a block structure. On a certain cross section formed along the width direction Y of the toothbrush head 100, the outer contour shape of the cross section of each hair implanting sheet 107 can be the same or different, and there is no limitation here. A hair implanting hole 1111 is provided on each hair implanting sheet 107, and bristles 1101 are provided in the hair implanting holes 1111 corresponding to each hair implanting sheet 107. Gaps are formed between adjacent hair implanting sheets 107, and the connecting portion 13 can also connect adjacent hair implanting sheets 107. When the hair implanting portion 11 is subjected to force, the connecting portion 13 is subjected to force and bends, so that the spacing between each adjacent hair implanting sheet 107 will also change.

[0058] Furthermore, in some embodiments, the hair implantation portion 11 may further include a first hair implantation portion 111 and a second hair implantation portion 113, wherein the first hair implantation portion 111 can be connected to the support portion 15, and the second hair implantation portion 113 can be spaced apart from the support portion 15. That is, the hair implantation portion 11 disposed in the first area 105 is the first hair implantation portion 111, and the hair implantation portion 11 disposed in the second area 106 is the second hair implantation portion 113. There is a gap between the first hair-planting portion 111 and the second hair-planting portion 113, and the first hair-planting portion 111 and the second hair-planting portion 113 are connected via the connecting portion 13. When the bristles 1101 are subjected to force and the connecting portion 13 is deformed, the second hair-planting portion 113 can move relative to the first hair-planting portion 111 to increase the distance between the first hair-planting portion 111 and the second hair-planting portion 113. At this time, the toothbrush head 100 will be deformed, and the bristles 1101 arranged on the first hair-planting portion 111 and the second hair-planting portion 113 will shift to contact different positions of the part to be cared for, so as to achieve cleaning of various positions of the part to be cared for.

[0059] Specifically, please combine Figure 4In some embodiments, in the length direction X of the toothbrush head 100, the second hair-planting portion 113 includes at least two, and the first hair-planting portion 111 is disposed between the at least two second hair-planting portions 113. In the case where the first hair-planting portion 111 is disposed between the at least two second hair-planting portions 113, the at least two second hair-planting portions 113 may be arranged along the length direction X of the toothbrush head 100. The first hair-planting portion 111 is located in the middle of the toothbrush head 100 along the length direction X of the toothbrush head 100 and is connected to the support portion 15. In other embodiments, in the width direction Y of the toothbrush head 100, the second hair-planting portion 113 includes at least two, and the first hair-planting portion 111 is disposed between the at least two second hair-planting portions 113. In the case where the first hair-planting portion 111 is disposed between the at least two second hair-planting portions 113, the at least two second hair-planting portions 113 may be arranged along the width direction Y of the toothbrush head 100. The first hair-planting portion 111 is located in the middle of the toothbrush head 100 along the width direction Y of the toothbrush head 100 and is connected to the support portion 15. When the bristles 1101 are subjected to force and the connecting portion 13 is deformed, at least two second hair-planting portions 113 can move in various directions away from the first hair-planting portion 111 with the first hair-planting portion 111 as the center, so that the bristles 1101 provided on the first hair-planting portion 111 and at least two second hair-planting portions 113 can contact different positions of the part to be cared for.

[0060] More specifically, please combine Figure 5 In some embodiments, in the length direction X of the toothbrush head 100, the first hair-planting parts 111 include at least two, and the support parts 15 include at least two. At least two support parts 15 are respectively connected to the at least two first hair-planting parts 111, and the second hair-planting part 113 is arranged on any side of the center line of the at least two support parts 15 in the width direction Y of the toothbrush head 100. The first hair-planting part 111 can correspond to the support part 15, and when the first hair-planting parts 111 include at least two, each first hair-planting part 111 can be connected to the support part 15. At this time, at least two first hair-planting parts 111 can be arranged along the length direction X of the toothbrush head 100, and there is still at least one first hair-planting part 111 arranged in the middle of the toothbrush head 100 in the length direction X of the toothbrush head 100 and / or in the width direction Y of the toothbrush head 100. The center line of at least two supporting parts 15 passes through the first hair-planting part 111 provided in the middle of the toothbrush head 100, and the second hair-planting part 113 can be provided on any side of the center line of at least two supporting parts 15 along the width direction Y of the toothbrush head 100. In the case where the second hair-planting part 113 includes two, the two second hair-planting parts 113 can be provided on both sides of the center line of at least two supporting parts 15 along the width direction Y of the toothbrush head 100.

[0061] More specifically, in some embodiments, the support portion 15 is also at least partially connected to the connecting portion 13 connected to the second hair-implanting portion 113. When the support portion 15 is connected to the connecting portion 13, when the connecting portion 13 is deformed, the support portion 15 can support the side of the connecting portion 13 away from the bristles 1101 to improve the strength of the connecting portion 13 and avoid the connecting portion 13 from breaking. Moreover, when the support portion 15 is connected to the connecting portion 13 and the hair-implanting portion 11 at the same time, the contact area between the support portion 15 and the connecting portion 13 and the hair-implanting portion 11 is large, the connection between the three is stable, and the toothbrush head 100 is not easily damaged.

[0062] Please combine Figure 6 In some embodiments, along the thickness direction Z of the toothbrush head 100, the thickness H1 of the connecting portion 13 is less than the thickness H2 of the hair-implanting portion 11. The thickness of the connecting portion 13 refers to the distance between the two opposite side surfaces of the connecting portion 13 along the thickness direction Z of the toothbrush head 100. The thickness of the hair-implanting portion 11 refers to the distance between the first side 101 and the second side 102 of the hair-implanting portion 11 opposite to each other along the thickness direction Z of the toothbrush head 100. In the case where the thickness H4 of the connecting portion 13 is less than the thickness H5 of the hair-implanting portion 11, the connecting portion 13 is more easily deformed under stress than the hair-implanting portion 11. In the case where adjacent hair-implanting portions 11 are spaced apart from each other, the hair-implanting portions 11 can move closer to and / or farther away from each other when the connecting portion 13 is deformed under stress, so that the bristles 1101 on the hair-implanting portion 11 move to different positions, thereby improving the cleaning effect of the toothbrush head 100.

[0063] Specifically, see Figures 3 to 5 In some embodiments, in the thickness direction Z of the toothbrush head 100, the surface of the connecting portion 13 away from the bristles 1101 is flush with the second surface 102. When the surface of the connecting portion 13 facing the supporting portion 15 is flush with the surface where the second side 133 of the hair-planting portion 11 is located, the side of the connecting portion 13 facing the bristles 1101 is located in the gap 104 between adjacent hair-planting portions 11. When the bristles 1101 are subjected to force, the bristles 1101 transfer the force to the hair-planting portion 11. At this time, the hair-planting portion 11 can only push the connecting portion 13 to bend toward the side away from the bristles 1101, but cannot bend toward the side close to the bristles 1101. The bristles 1101 have better wrapping properties for the care portion and better cleaning effect. When the thickness H1 of the connecting portion 13 is small, the connecting portion 13 is too thin and is easy to break when subjected to force. When the thickness H1 of the connecting portion 13 is moderate, the connecting portion 13 can be deformed under force without being damaged.

[0064] See also Figure 2 and Figure 3In some embodiments, the toothbrush head 100 further includes a deformable portion 19 that is deformable under force, and the deformable portion 19 is a protective and supporting structure made of a flexible material such as soft glue. The deformable portion 19 is combined with at least one of the hair-planting portion 11, the connecting portion 13 and the supporting portion 15 to support and / or protect the portion combined with the deformable portion 19.

[0065] Specifically, in some embodiments, the hair implanting portion 11 also includes a peripheral side portion 103 connected to the first side 101 of the hair implanting portion 11 and the second side 102 of the hair implanting portion 11, respectively, and the deformation portion 19 can wrap the second side 102 of the hair implanting portion 11 and at least part of the peripheral side portion 103 of the hair implanting portion 11 to avoid collision between the hair implanting portion 11 and the portion to be cared for. In addition, the deformation portion 19 that wraps the second side 102 of the hair implanting portion 11 and at least part of the peripheral side portion 103 of the hair implanting portion 11 is not easy to fall off from the hair implanting portion 11, and there is no obvious boundary between the deformation portion 19 and the hair implanting portion 11, so it is not easy to form dirt deposition.

[0066] More specifically, in some embodiments, the top of the hair-implanting portion 11 protrudes from the deformation portion 19. The deformation portion 19 can be formed on the surface of the hair-implanting portion 11, the connecting portion 13 and / or the supporting portion 15 by hot-melting the soft rubber material and then solidifying it again. When the first surface protrudes compared to the deformation portion 19, the soft rubber material in a fluid state will not enter the hair-implanting hole 1111 provided on the first surface of the brush plate, thereby preventing the bristles 1101 from being difficult to install in the hair-implanting hole 1111.

[0067] More specifically, in some embodiments, the deformation portion 19 can also be used to fill the gap between adjacent hair-planting portions 11 and support the connecting portion 13. When the deformation portion 19 fills the gap between adjacent hair-planting portions 11 and supports the connecting portion 13, the hair-planting portions 11 and the connecting portion 13 will squeeze the deformation portion 19 to partially deform the deformation portion 19, and the squeezed deformation portion 19 can also provide support for the hair-planting portions 11 and the connecting portion 13 to reduce damage to the hair-planting portions 11 and the connecting portion 13 during use, and the toothbrush head 100 can be more durable.

[0068] Specifically, please combine Figure 5 In some embodiments, the deformation portion 19 can also fill the gap between adjacent hair-planting sheets 107 and support each hair-planting sheet 107 and the connecting portion 13 between each adjacent hair-planting sheet 107. Each hair-planting sheet 107 can be connected to the deformation portion 19, and when the deformation portion 19 wraps the bottom and side wall of each hair-planting sheet 107 and fills the gap between adjacent hair-planting sheets 107, the surface of the toothbrush head 100 is prevented from being uneven, and dirt can also be prevented from remaining on the toothbrush head 100, which affects the normal use of the toothbrush head 100.

[0069] Furthermore, in some embodiments, the two opposite sides of the connecting portion 13 along the thickness direction Z of the toothbrush head 100 will face the gap 104 between the hair-planting portions 11, and the deformable portion 19 for protection and filling can fill the gap 104 between the hair-planting portions 11 and wrap the opposite sides of the connecting portion 13 to protect the connecting portion 13 and prevent the connecting portion 13 from breaking. Specifically, in some embodiments, the deformable portion 19 can also cover the opposite sides of the connecting portion 13 along the thickness direction Z of the toothbrush head 100. When the thickness of the connecting portion 13 is less than the thickness of the hair-planting portion 11, the connecting portion 13 is more easily deformed under stress than the hair-planting portion 11. The two opposite sides of the connecting portion 13 along the thickness direction Z of the toothbrush head 100 will face the gap 104 between the hair-implanted portions 11. The deformation portion 19 used for protection and filling can respectively cover and support the two opposite sides of the connecting portion 13 through the gap 104 between the hair-implanted portions 11 and the second side 102 of the hair-implanted portions 11 to protect the connecting portion 13 and prevent the connecting portion 13 from breaking.

[0070] See also Figure 2 and Figure 3 , and combined with Figure 8 In some embodiments, the toothbrush head 100 may further include a mounting portion 17, which is a structure capable of connecting to the handle 300 of the electric toothbrush 1000 and transmitting vibrations. The mounting portion 17 is connected to the end of the support portion 15 away from the hair-planting portion 11, and a gap is provided between the mounting portion 17 and the hair-planting portion 11. In the case where a gap is provided between the mounting portion 17 and the hair-planting portion 11, when the connection portion 13 is deformed to cause the size of the gap 104 between adjacent hair-planting portions 11 to change, the gap between the mounting portion 17 and the hair-planting portion 11 can provide space for the hair-planting portion 11 to move, so that the bristles 1101 on the hair-planting portion 11 can move relative to the mounting portion 17. The deformable portion 19 for protection and filling can wrap the bottom of the mounting portion 17 (i.e., the side of the mounting portion 17 away from the second side 102 of the hair-planting portion 11) and the side of the mounting portion 17, fill the gap between the mounting portion 17 and the hair-planting portion 11, and support the connecting portion 13, so as to prevent the hair-planting portion 11 from being subjected to excessive force and causing the connecting portion 13 to break.

[0071] See also Figure 2 and Figure 8 The electric toothbrush 1000 of the present application includes a toothbrush head 100 and a brush handle 300 as described in any of the above embodiments, and the toothbrush head 100 is installed on the brush handle 300.

[0072] In the electric toothbrush 1000 of the present application, the brush handle 300 can vibrate and transmit the vibration to the bristles 1101 on the toothbrush head 100. When the brush body 10 is subjected to force, the connecting portion 13 will be deformed by force to change the distance between adjacent hair-planting portions 11. At this time, the bristles 1101 arranged on the hair-planting portions 11 will fit on the surface of the teeth in contact with it and in the gaps between the teeth. Therefore, when the toothbrush head 100 vibrates, the vibrating bristles 1101 clean the surface of the teeth and the gaps between the teeth more fully, and the cleaning effect is better.
