Description

Technical Field

[0001] The present application relates to the technical field of electric toothbrushes, and in particular to an electric toothbrush head and an electric toothbrush. Background Art

[0002] With the improvement of living standards, electric toothbrushes have gradually entered the daily lives of many people. People's requirements for electric toothbrushes are no longer just to meet the needs of simple brushing, but they are beginning to pay more attention to the brushing experience.

[0003] However, in the related art, electric toothbrush heads have different degrees of tooth-rubbing phenomena, which cause great irritation to the teeth and give users a bad experience. Utility Model Content

[0004] In response to the above-mentioned deficiencies in the related art, the present application provides an electric toothbrush head and an electric toothbrush to solve the problem in the related art that the electric toothbrush head causes a bad user experience due to the teeth being scratched.

[0005] In order to solve the above technical problems, in a first aspect, the present application provides an electric toothbrush head, which includes:

[0006] Brush board;

[0007] a soft rubber layer, the soft rubber layer being wrapped around the outer side of the brush plate, the brush plate and / or the soft rubber layer being provided with a bristle surface;

[0008] Bristles, one end of each of the bristles being fixedly connected to the bristle surface;

[0009] A buffer protrusion structure is provided on the outer surface of the soft rubber layer away from the brush plate.

[0010] In the present application, since the outer side of the brush plate is wrapped with a soft rubber layer, and since the buffering protrusion structure is protruding from the outer surface of the soft rubber layer away from the brush plate, when the electric toothbrush head accidentally collides with the teeth during use, not only can the soft rubber layer reduce a certain amount of impact force, which is beneficial to reduce the discomfort and potential damage caused by teething to a certain extent, but more importantly, the buffering protrusion structure protruding from the soft rubber layer can first contact the teeth and deform to absorb most of the collision energy, thereby reducing the direct impact on the teeth, which is beneficial to further enhance the buffering effect, further reduce the discomfort and potential damage caused by teething, and further improve the user experience.

[0011] In a possible implementation of the first aspect, the outer surface includes a back surface and a side surface, the back surface is spaced apart from and disposed opposite to the bristle surface, and the side surface is connected between the bristle surface and the back surface;

[0012] The buffer protrusion structure is protruded from the side surface.

[0013] Since the side of the electric toothbrush head is more likely to contact the teeth during brushing, that is, the side on the outer surface is more likely to contact the teeth, therefore, protruding the buffering protrusion structure on the side can more effectively reduce the direct impact on the teeth, which is conducive to further enhancing the buffering effect.

[0014] In a possible implementation of the first aspect, the electric toothbrush head further includes a rod portion, and the rod portion is connected to the brush plate;

[0015] The buffer protrusion structure includes a first buffer protrusion and a second buffer protrusion. In a direction different from the length direction of the rod, the first buffer protrusion and the second buffer protrusion are respectively located on both sides of the brush plate.

[0016] In a direction different from the length direction of the rod, since the electric toothbrush head has more vibration movements, the first buffer protrusion and the second buffer protrusion are respectively arranged on both sides of the brush plate in a direction different from the length direction of the rod, which is beneficial to provide comprehensive buffer protection and further reduce direct impact on the teeth.

[0017] In a possible implementation of the first aspect, the buffer protrusion structure further includes a third buffer protrusion. In the length direction of the rod, the third buffer protrusion is located on a side of the brush plate away from the rod.

[0018] A third bump is added along the length of the shaft, on the side of the brush plate away from the shaft. This further improves the range of the bump protection, providing more comprehensive cushioning protection and further reducing direct impact on the teeth. Furthermore, adding the third bump, in addition to the first and second bumps, eliminates the need for a continuous bump along the entire side, reducing consumables and costs.

[0019] In a possible implementation of the first aspect, an extension length of the third buffer protrusion is greater than or equal to an extension length of the first buffer protrusion; and / or,

[0020] An extension length of the third buffer protrusion is greater than or equal to an extension length of the second buffer protrusion.

[0021] During the toothbrushing process, since the user usually applies force along the length of the rod to drive the electric toothbrush head to move in the mouth, the third buffer protrusion located on the side of the brush plate away from the rod undertakes the main buffering task. The longer extension length can provide a larger buffering stroke and more effective buffering force, which greatly reduces damage to the teeth and improves the user's comfort.

[0022] In a possible implementation of the first aspect, at least one of the first buffer protrusion, the second buffer protrusion, and the third buffer protrusion is a strip-shaped protrusion; or,

[0023] At least one of the first buffer protrusion, the second buffer protrusion, and the third buffer protrusion comprises a plurality of linear protrusions arranged in parallel and at intervals; or

[0024] At least one of the first buffer protrusion, the second buffer protrusion, and the third buffer protrusion includes a plurality of circular protrusions arranged at intervals.

[0025] First, the buffering protrusion is set as a strip-shaped protrusion. Since the strip-shaped protrusion can provide a larger contact area and a longer buffering stroke, it can evenly disperse the impact force when a collision occurs and enhance the buffering effect. At the same time, the structure of the strip-shaped protrusion is relatively simple and easy to manufacture.

[0026] Secondly, the buffering protrusions are arranged as multiple parallel, spaced linear protrusions. The spacing allows each linear protrusion to deform independently when subjected to pressure, thus adapting to collisions of varying directions and intensities, providing cushioning while maintaining a certain degree of flexibility. Furthermore, the spaces between them allow for a certain amount of air and water flow, facilitating ventilation and flushing during the cleaning process, improving cleaning efficiency.

[0027] Third, the cushioning protrusions are arranged as multiple, spaced circular protrusions. Their rounded shape disperses the impact force in all directions during a collision, reducing localized concentrated stress and lowering the risk of injury. Multiple, spaced circular protrusions increase cushioning diversity and adaptability, ensuring that some protrusions effectively cushion the impact regardless of the angle of impact.

[0028] In a possible implementation of the first aspect, the thickness of the soft rubber layer ranges from 0.4 mm to 2 mm.

[0029] This design, on the one hand, provides sufficient cushioning capacity to absorb and mitigate the impact when the electric toothbrush head collides with teeth, reducing pain and the risk of injury from tooth impaction. On the other hand, it ensures that the soft rubber layer, while providing cushioning, also has a certain structural strength, making it less susceptible to breakage or damage.

[0030] In a possible implementation of the first aspect, a protrusion thickness of the buffer protrusion structure is greater than or equal to 0.3 mm.

[0031] This design, firstly, allows for a greater cushioning effect due to the thicker bumps. When the electric toothbrush head collides with teeth, the thicker bumps deform more, absorbing more energy and mitigating the impact more effectively, reducing discomfort and potential damage.

[0032] Secondly, the greater convex thickness helps to increase the gap between the electric toothbrush head and the contact parts such as teeth and gums. This can reduce the possibility of direct contact between the brush plate or other hard parts of the teeth and gums, reducing the risk of wear and scratching.

[0033] Furthermore, sufficient protrusion thickness ensures that the cushioning protrusion structure can maintain its cushioning performance after long-term use and frequent collisions. Smaller protrusion thickness may easily wear or deform after repeated use, while protrusions with a thickness greater than or equal to 0.3mm have better durability.

[0034] In addition, this size setting also facilitates manufacturing and quality control. During mold design and processing, sizes of 0.3mm and above make it easier to achieve precise molding and consistent production.

[0035] In a possible implementation of the first aspect, a protrusion thickness of the buffer protrusion structure is less than or equal to a thickness of the soft rubber layer.

[0036] This arrangement ensures, to a certain extent, that the cushioning protrusions have an appropriate thickness, providing just the right cushioning effect when the electric toothbrush head strikes the teeth. It's neither too thin to effectively absorb impact energy, nor too thick to provide excessive cushioning, affecting the proper transmission of brushing force. It also matches the thickness of the soft rubber layer, optimizing the overall cushioning effect and providing a more comfortable brushing experience.

[0037] In a possible implementation of the first aspect, the buffer protrusion structure and the soft rubber layer are integrally formed.

[0038] This setup, on the one hand, eliminates gaps or weak points between the bump structure and the soft rubber layer due to the one-piece molding process. This ensures the stability of the entire structure, allowing it to withstand frequent external forces and extend the life of the electric toothbrush head. Furthermore, this one-piece molding process reduces the number of assembly steps and parts, which not only improves production efficiency and reduces production costs, but also reduces quality issues caused by assembly errors. Furthermore, the one-piece molding process allows for higher dimensional accuracy, ensuring consistent quality across each electric toothbrush head.

[0039] In a possible implementation of the first aspect, the hardness value of the buffer protrusion structure is in the range of 35HA-70HA; and / or the hardness value of the soft rubber layer is in the range of 35HA-70HA.

[0040] Such a setting, first of all, can provide a moderate cushioning effect, so that it will not be too soft to effectively resist collision impact, nor will it lose its cushioning effect because it is too hard. Secondly, it can maintain a certain degree of support, so as to ensure that during the brushing process, it can play a certain guiding and restricting role on the movement of the toothbrush head, making the brushing action more stable and controllable. Furthermore, for teeth and gums with different sensitivities, this hardness range can provide more general comfort and can adapt to different oral environments. In addition, moderate hardness can maintain good performance and shape during long-term use and frequent collisions, and is not prone to excessive deformation or damage, thereby extending the service life of the electric toothbrush head.

[0041] In a possible implementation of the first aspect, a hardness value of the buffer protrusion structure is smaller than a hardness value of the soft rubber layer.

[0042] Such a setting can make the buffering protrusion structure softer than the soft rubber layer, so that when the toothbrush head contacts the oral cavity, the buffering protrusion structure can enhance comfort, which is conducive to further improving the user experience. At the same time, the buffering protrusion structure can further reduce the direct impact on the teeth, which is conducive to further reducing the discomfort and potential damage caused by teething.

[0043] In a second aspect, the present application further provides an electric toothbrush, comprising:

[0044] handle;

[0045] The electric toothbrush head according to any one of the first aspects;

[0046] A toothbrush driving member is provided on the handle, and an output shaft of the toothbrush driving member is detachably connected to the electric toothbrush head. The toothbrush driving member is used to drive the electric toothbrush head to move.

[0047] In the present application, since the outer side of the brush plate in the electric toothbrush head is wrapped with a soft rubber layer, and since the buffering protrusion structure is protruding from the outer surface of the soft rubber layer away from the brush plate, when the electric toothbrush accidentally collides with the teeth during use, not only can the soft rubber layer reduce a certain amount of impact force, which is beneficial to reduce the discomfort and potential damage caused by teething to a certain extent, but more importantly, the buffering protrusion structure protruding from the soft rubber layer can first contact the teeth and deform to absorb most of the collision energy, thereby reducing the direct impact on the teeth, which is beneficial to further enhance the buffering effect, further reduce the discomfort and potential damage caused by teething, and further improve the user experience.

[0068] As described in the background technology of this application, with the improvement of living standards, electric toothbrushes have gradually entered the daily lives of many people. People's requirements for electric toothbrushes are no longer just to meet the needs of simple brushing, but they are beginning to pay more attention to the brushing experience.

[0069] However, in the related art, electric toothbrush heads have different degrees of tooth-rubbing phenomena, which cause great irritation to the teeth and give users a bad experience.

[0070] Example 1

[0071] In view of the above-mentioned problems, the present application provides an electric toothbrush head to solve the problem in the related art that the electric toothbrush head causes a bad user experience due to the teeth being scratched.

[0072] The technical solution of this application will be further described below with reference to specific embodiments and drawings:

[0073] like Figure 1、 Figure 2 、 Figure 3 and Figure 4 As shown, the electric toothbrush head 100 includes a brush plate 1, a soft rubber layer 2, bristles 3, and a buffering protrusion structure 4. The soft rubber layer 2 is wrapped around the outside of the brush plate 1, and a bristle surface 5 is provided on the brush plate 1 and / or the soft rubber layer 2. One end of the bristles 3 is fixedly connected to the bristle surface 5. The buffering protrusion structure 4 is protruded from the outer surface of the soft rubber layer 2 away from the brush plate 1.

[0074] In the present application, since the outer side of the brush plate 1 is wrapped with a soft rubber layer 2, and since the buffering protrusion structure 4 is protruded from the outer surface of the soft rubber layer 2 away from the brush plate 1, when the electric toothbrush head 100 accidentally collides with the teeth during use, not only can the soft rubber layer 2 reduce a certain impact force, which is beneficial to reduce the discomfort and potential damage caused by teething to a certain extent, but more importantly, the buffering protrusion structure 4 protruding from the soft rubber layer 2 can first contact the teeth and deform to absorb most of the collision energy, thereby reducing the direct impact on the teeth, which is beneficial to further enhance the buffering effect, further reduce the discomfort and potential damage caused by teething, and further improve the user experience.

[0075] Furthermore, if Figure 1 、 Figure 2 and Figure 3 As shown, the outer surface of the soft rubber layer 2 includes a back surface 21 and a side surface 22 . The back surface 21 is spaced apart from and opposite to the bristle surface 5 . The side surface 22 is connected between the bristle surface 5 and the back surface 21 . The buffer protrusion structure 4 is protruded from the side surface 22 .

[0076] During the brushing process, the side of the electric toothbrush head 100 is more likely to contact the teeth, that is, the side 22 on the outer surface is more likely to contact the teeth. Therefore, the buffer protrusion structure 4 is protruded on the side 22, which can more effectively reduce the direct impact on the teeth and help further enhance the buffering effect.

[0077] In other embodiments, the buffer protrusion structure 4 can also be protruded from the back side 21 or the back side 21 and the side surface 22. The setting of the buffer protrusion structure 4 on the outer surface of the soft rubber layer 2 is relatively flexible, and can be specifically selected according to actual usage requirements.

[0078] In the first embodiment of the buffer protrusion structure 4, the buffer protrusion structure 4 includes only one buffer protrusion (not shown), and the buffer protrusion can be set on one side of the brush plate 1 on the side 22, or can also be set around the brush plate 1 on the side 22.

[0079] With such a configuration, since the buffer protrusion structure 4 only includes one buffer protrusion, the structure of the buffer protrusion structure 4 is relatively simple, which facilitates the processing of the buffer protrusion structure 4.

[0080] In the second embodiment of the buffer protrusion structure 4 , the buffer protrusion structure 4 includes two buffer protrusions, and in the length direction of the rod 6 , the two buffer protrusions are located on the side of the brush plate 1 away from the rod 6 (not shown).

[0081] This arrangement, on the one hand, provides a larger buffering area and stronger buffering force through the combined action of the two buffering protrusions along the length of the rod 6, thereby significantly reducing the impact intensity on the teeth and alleviating the user's discomfort caused by tooth impaction when brushing. On the other hand, by providing two buffering protrusions along the length of the rod 6, the pressure borne by a single buffering protrusion can be shared, thereby extending the service life of the buffering protrusion structure 4, improving the durability of the electric toothbrush head 100, and reducing the need for frequent replacement of the toothbrush head due to damage to the buffering protrusion structure 4, thereby saving the user's usage costs.

[0082] In the third embodiment of the buffer protrusion structure 4, as shown in FIG. Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the electric toothbrush head 100 further includes a rod 6, which is connected to the brush plate 1. The buffer protrusion structure 4 includes a first buffer protrusion 41 and a second buffer protrusion 42, which are arranged in a direction different from the length direction of the rod 6 (such as Figure 2 In the X direction), the first buffer protrusion 41 and the second buffer protrusion 42 are respectively located on both sides of the brush plate 1.

[0083] In a direction different from the length direction of the rod 6, since the electric toothbrush head 100 has more vibration movements, the first buffer protrusion 41 and the second buffer protrusion 42 are respectively arranged on both sides of the brush plate 1 in a direction different from the length direction of the rod 6, which is beneficial to provide comprehensive buffer protection and further reduce the direct impact on the teeth.

[0084] In the fourth embodiment of the buffer protrusion structure 4, as shown in FIG. Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, based on the third embodiment, the buffer protrusion structure 4 further includes a third buffer protrusion 43 . In the length direction of the rod 6 , the third buffer protrusion 43 is located on the side of the brush plate 1 away from the rod 6 .

[0085] This arrangement, on the one hand, facilitates comprehensive buffering protection through the first and second buffering protrusions 41, 42 in a direction different from the length of the rod 6. On the other hand, the provision of a third buffering protrusion 43 on the side of the brush plate 1 away from the rod 6 along the length of the rod 6 further improves the scope of buffering protection, enabling more comprehensive buffering protection, thereby further helping to reduce direct impact on the teeth. Furthermore, providing the third buffering protrusion 43 in addition to the first and second buffering protrusions 41, 42 eliminates the need for a continuous buffering protrusion along the entire side 22, which helps reduce consumables and costs.

[0086] In the fourth embodiment, further, the extension length of the third buffer protrusion 43 is greater than or equal to the extension length of the first buffer protrusion 41 ; and / or the extension length of the third buffer protrusion 43 is greater than or equal to the extension length of the second buffer protrusion 42 .

[0087] During the brushing process, since the user usually applies force along the length direction of the rod 6 to drive the electric toothbrush head 100 to move in the mouth, the third buffer protrusion 43 located on the side of the brush plate 1 away from the rod 6 undertakes the main buffering task. The longer extension length can provide a larger buffering stroke and more effective buffering force, greatly reducing damage to the teeth and improving the user's comfort.

[0088] In addition, it should be noted that, in this embodiment, the size relationship between the extension lengths of the first buffer protrusion 41, the second buffer protrusion 42 and the third buffer protrusion 43 is not limited, and can be specifically set according to actual needs.

[0089] In a fifth embodiment of the buffer protrusion structure 4 , the buffer protrusion structure 4 includes a plurality of buffer protrusions, and the plurality of buffer protrusions are spaced apart and distributed along the longitudinal extension direction of the side surface 22 (not shown).

[0090] This arrangement allows multiple buffering protrusions to work together at different locations, covering a wider area. No matter from which angle the electric toothbrush head 100 contacts the teeth, there is a high probability that a buffering protrusion will be present near the contact point to provide cushioning. This provides all-round buffering protection, greatly reducing the adverse effects of toothbrushing and improving the user experience.

[0091] In this embodiment, the buffer protrusion structure 4 may include four, five, six or more buffer protrusions. The number of buffer protrusions in this embodiment is flexible. Specifically, it can be set according to actual needs, and this is not specifically limited in this embodiment.

[0092] Regarding the structures of the first buffer protrusion 41, the second buffer protrusion 42 and the third buffer protrusion 43, as shown in FIG. Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, at least one of the first buffer protrusion 41 , the second buffer protrusion 42 and the third buffer protrusion 43 is a strip-shaped protrusion.

[0093] With such a configuration, since the strip-shaped protrusions can provide a larger contact area and a longer buffering stroke, the impact force can be evenly dispersed when a collision occurs, thereby enhancing the buffering effect. At the same time, the structure of the strip-shaped protrusions is relatively simple and easy to manufacture.

[0094] In a preferred embodiment, Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the first buffer protrusion 41 , the second buffer protrusion 42 and the third buffer protrusion 43 are all strip-shaped protrusions.

[0095] With such arrangement, the buffering protrusion structure 4 can provide a larger contact area and a longer buffering stroke, so that the impact force can be dispersed more evenly when a collision occurs, and the buffering effect can be further enhanced.

[0096] In an optional embodiment, at least one of the first buffer protrusion 41 , the second buffer protrusion 42 , and the third buffer protrusion 43 includes a plurality of linear protrusions that are parallel and spaced apart.

[0097] This arrangement allows each linear protrusion to deform independently when subjected to pressure, adapting to collisions of varying directions and intensities. It provides cushioning while maintaining a certain degree of flexibility. Furthermore, the spaces between the protrusions allow for a certain amount of air and water flow, facilitating ventilation and flushing during cleaning, improving cleaning efficiency.

[0098] In an optional embodiment, at least one of the first buffer protrusion 41 , the second buffer protrusion 42 and the third buffer protrusion 43 includes a plurality of circular protrusions arranged at intervals.

[0099] This arrangement allows the circular protrusions to disperse the impact force in all directions during an impact, reducing localized stress and minimizing the risk of injury. Multiple, spaced-apart circular protrusions increase cushioning diversity and adaptability, ensuring that some protrusions effectively cushion the impact regardless of the angle of impact.

[0100] In other embodiments, the first buffer protrusion 41, the second buffer protrusion 42 and the third buffer protrusion 43 can also be square protrusions, trapezoidal protrusions or protrusions of any other shape. The shape settings of the first buffer protrusion 41, the second buffer protrusion 42 and the third buffer protrusion 43 are relatively flexible and can be specifically set according to actual needs.

[0101] In addition, it should be noted that in each embodiment of the buffer protrusion structure 4, the shape structure of the buffer protrusion can be the same as or different from the shape structure of the first buffer protrusion 41, the second buffer protrusion 42 and the third buffer protrusion 43, and this embodiment does not make specific limitations on this.

[0102] Regarding the thickness of the soft rubber layer 2 , further, the thickness of the soft rubber layer 2 is in the range of 0.4 mm to 2 mm.

[0103] This arrangement, on the one hand, can provide sufficient cushioning capacity to absorb and mitigate the impact force when the electric toothbrush head 100 collides with the teeth, reducing the pain and risk of injury caused by tooth collision. On the other hand, it ensures that the soft rubber layer 2 has a certain structural strength while providing cushioning, making it difficult to break or damage.

[0104] In this embodiment, the thickness of the soft rubber layer 2 can be 0.4mm, 2mm or any value within the range of 0.4mm-2mm. The thickness setting of the soft rubber layer 2 is relatively flexible. Specifically, it can be set according to actual usage requirements. The embodiment of this application does not make specific limitations on this.

[0105] Regarding the size of the buffer protrusion structure 4 , further, the protrusion thickness of the buffer protrusion structure 4 is greater than or equal to 0.3 mm.

[0106] In this configuration, first, the thicker protrusions can provide a more significant cushioning effect. When the electric toothbrush head 100 collides with the teeth, the thicker protrusions can produce greater deformation and absorb more energy, thereby more effectively reducing the impact force and reducing the discomfort and potential damage caused by the impact.

[0107] Secondly, the greater protrusion thickness helps to increase the gap between the electric toothbrush head 100 and the contact parts such as teeth and gums. This can reduce the possibility of the brush plate 1 or other hard parts directly contacting the teeth and gums, reducing the risk of wear and scratching.

[0108] Furthermore, sufficient protrusion thickness can ensure that the buffer protrusion structure 4 can still maintain its buffering performance after long-term use and frequent collisions. Smaller protrusion thickness may be easily worn or deformed after repeated use, while protrusions with a thickness greater than or equal to 0.3 mm have better durability.

[0109] In addition, this size setting also facilitates manufacturing and quality control. During mold design and processing, sizes of 0.3mm and above make it easier to achieve precise molding and consistent production.

[0110] In the embodiment of the present application, the protrusion thickness of the buffering protrusion structure 4 can be 0.3mm, 0.4mm, 0.5mm or any value greater than 0.3mm. The protrusion thickness of the buffering protrusion structure 4 is flexibly set. Specifically, it can be set according to actual usage requirements. The embodiment of the present application does not make specific limitations on this.

[0111] Regarding the thickness relationship between the buffer protrusion structure 4 and the soft adhesive layer 2 , further, the protrusion thickness of the buffer protrusion structure 4 is less than or equal to the thickness of the soft adhesive layer 2 .

[0112] This arrangement, to a certain extent, allows the cushioning protrusion structure 4 to have a moderate thickness, enabling it to provide just the right cushioning effect when the electric toothbrush head 100 is used to brush teeth. It is neither too thin to effectively absorb the impact energy, nor too thick to provide excessive cushioning force, affecting the normal force transmission during brushing. It also matches the thickness of the soft rubber layer 2, optimizing the overall cushioning effect and providing the user with a more comfortable brushing experience.

[0113] Regarding the molding of the buffer protrusion structure 4 and the soft rubber layer 2, further, the buffer protrusion structure 4 and the soft rubber layer 2 are integrally molded.

[0114] This arrangement, on the one hand, eliminates gaps or weak points between the bump structure 4 and the soft rubber layer 2 due to the integrated molding process. This ensures the stability of the entire structure, allowing it to withstand frequent external forces and extend the service life of the electric toothbrush head 100. Furthermore, integrated molding reduces the number of assembly steps and parts, which not only improves production efficiency and reduces production costs, but also reduces quality issues caused by assembly errors. Furthermore, the integrated molding process allows for higher dimensional accuracy of the product, ensuring consistent quality across each electric toothbrush head 100.

[0115] Regarding the hardness values ​​of the buffer protrusion structure 4 and the soft rubber layer 2 , further, the hardness value of the buffer protrusion structure 4 is in the range of 35HA-70HA; and / or, the hardness value of the soft rubber layer 2 is in the range of 35HA-70HA.

[0116] Such a setting, firstly, can provide a moderate cushioning effect, so that it will not be too soft to effectively resist collision impact, nor will it lose its cushioning effect because it is too hard. Secondly, it can maintain a certain degree of support, so as to ensure that during the brushing process, it can play a certain guiding and limiting role on the movement of the toothbrush head, making the brushing action more stable and controllable. Furthermore, for teeth and gums with different sensitivities, this hardness range can provide more general comfort and can adapt to different oral environments. In addition, moderate hardness can maintain good performance and shape during long-term use and frequent collisions, and is not prone to excessive deformation or damage, thereby extending the service life of the electric toothbrush head 100.

[0117] In a preferred embodiment, the hardness values ​​of both the buffer protrusion structure 4 and the soft rubber layer 2 are in the range of 35HA-70HA.

[0118] Such a configuration can further ensure the comfort of the electric toothbrush head 100, which is conducive to further enhancing the user experience.

[0119] In this embodiment, the hardness value of the buffer protrusion structure 4 can be 35HA, 70HA or any value within the range of 35HA-70HA. The hardness value setting of the buffer protrusion structure 4 is relatively flexible. Specifically, it can be set according to actual usage requirements. The embodiment of this application does not make specific limitations on this.

[0120] In this embodiment, the hardness value of the soft rubber layer 2 can be 35HA, 70HA or any value within the range of 35HA-70HA. The hardness value setting of the soft rubber layer 2 is relatively flexible. Specifically, it can be set according to actual usage requirements. The embodiment of this application does not make specific limitations on this.

[0121] In one embodiment, when the buffer protrusion structure 4 and the soft rubber layer 2 are integrally formed, the hardness of the buffer protrusion structure 4 is equal to the hardness of the soft rubber layer 2 .

[0122] Since the buffer protrusion structure 4 and the soft rubber layer 2 are integrally formed, the hardness values ​​of the two are set to be equal, which is conducive to facilitating the integral forming of the buffer protrusion structure 4 and the soft rubber layer 2.

[0123] In another embodiment, when the buffer protrusion structure 4 and the soft rubber layer 2 are not integrally formed, the hardness of the buffer protrusion structure 4 is smaller than the hardness of the soft rubber layer 2 .

[0124] Such a setting can make the buffering protrusion structure 4 softer than the soft rubber layer 2, so that when the toothbrush head contacts the oral cavity, the buffering protrusion structure 4 can enhance comfort, which is conducive to further improving the user experience. At the same time, the buffering protrusion structure 4 can also further reduce the direct impact on the teeth, which is conducive to further reducing the discomfort and potential damage caused by teething.

[0125] Regarding the setting of the bristle surface 5 , in one embodiment, the bristle surface 5 is separately set on the brush plate 1 .

[0126] With such an arrangement, the bristle surface 5 of different materials, hardness or shapes can be replaced according to specific needs, making the arrangement of the bristle surface 5 on the brush plate 1 more flexible, which is beneficial to improving the versatility of the product.

[0127] In a preferred embodiment, the bristle surface 5 is integrally provided on the brush plate 1 .

[0128] In this way, the bristle surface 5 can be integrally formed on the brush plate 1, which facilitates the arrangement of the bristle surface 5 on the brush plate 1. In addition, since the brush plate 1 has a relatively stronger structural strength, the bristle surface is integrally arranged on the brush plate 1, which is conducive to enhancing the reliability of the bristle arrangement.

[0129] Regarding the arrangement of the bristles 3 on the bristle surface 5, further, a plurality of bristle planting holes (not shown in the figure) are provided on the bristle surface 5, and a plurality of bristles 3 are planted in each of the bristle planting holes.

[0130] First, by embedding multiple bristles 3 within a limited space, the distribution of bristles 3 per unit area is increased, enhancing the cleaning effect. Second, the combined effect of the multiple bristles 3 increases the frictional force in contact with the teeth, improving the intensity and efficiency of cleaning. Furthermore, the multiple bristles 3 share the pressure of brushing, distributing it more evenly across the teeth and gums, reducing damage caused by excessive localized pressure. Furthermore, the reliability of the placement of the bristles 3 on the brushing surface 5 is ensured.

[0131] Furthermore, there is an angle between the central axes of any two adjacent hair implantation holes, and the range of the angle is -5°-5°.

[0132] First, a smaller angle helps increase the variety of contact between the bristles 3 and the teeth, allowing the bristles 3 to more effectively reach difficult-to-clean areas such as gaps between teeth and the junction between teeth and gums. Second, this arrangement reduces the resistance of the bristles 3 to the same direction during cleaning. When the bristles 3 contact the teeth at different angles, the force applied during brushing is dispersed, reducing excessive wear on the teeth and gums.

[0133] In this embodiment, the angle between the central axes of two adjacent hair implantation holes can be any value within the range of -5°, 5° or -5°-5°. The size of the angle can be set flexibly. Specifically, it can be set according to actual usage requirements. The embodiment of the present application does not make specific limitations on this.

[0134] As for the bristles 3, in this embodiment, the bristles 3 are any one of copper-implanted bristles, copper-free bristle-implanted bristles, and injection-molded bristle-implanted bristles.

[0135] When the bristles 3 are copper-implanted, i.e., the bristles 3 are implanted in the implantation holes using a copper-implanted process, copper has antibacterial properties that inhibit the growth and reproduction of bacteria on the bristles 3, thereby helping to keep the bristles 3 clean and hygienic. Furthermore, due to the antibacterial effect, the bristles 3 are less likely to age or become damaged by bacteria, thereby extending the life of the toothbrush.

[0136] When the bristles 3 are copper-free implanted bristles, the bristles 3 can be fixed in the brush head by modular assembly or other methods, which can reduce the place and probability of bacterial growth, and is more hygienic and healthy. At the same time, the process is more mature and convenient for processing and manufacturing.

[0137] When the bristles 3 are injection-molded planted bristles, since the brush filaments and the brush head are integrated into one by injection molding, the bonding force between the bristles 3 and the brush head is high, the integrity is good, the bristles 3 are not easy to fall off, and the durability is strong.

[0138] As for the materials of the brush plate 1 and the soft rubber layer 2, in this embodiment, the material of the brush plate 1 is hard rubber, and the material of the soft rubber layer 2 is soft rubber.

[0139] Since hard rubber generally has high strength and rigidity, the brush plate 1 is made of hard rubber to enhance its strength and rigidity, thereby providing more reliable structural support. Since soft rubber has a soft texture, the soft rubber layer 2 is made of soft rubber to not only achieve a better cushioning effect but also provide a more comfortable touch for the user.

[0140] Furthermore, the brush plate 1 is made of acrylonitrile-butadiene-styrene copolymer or polycarbonate, and the soft rubber layer 2 is made of thermoplastic elastic material or thermoplastic polyurethane elastic material.

[0141] The brush plate 1 is made of acrylonitrile-butadiene-styrene copolymer or polycarbonate. Since acrylonitrile-butadiene-styrene copolymer (ABS) and polycarbonate (PC) have high strength and rigidity, they can provide stable support for the bristles, ensuring that the brush plate 1 is not easily deformed during brushing. At the same time, it is also conducive to manufacturing various complex shapes and structures to meet different design requirements.

[0142] The soft rubber layer 2 is made of thermoplastic elastomer or thermoplastic polyurethane. Due to their excellent elasticity and flexibility, thermoplastic elastomer (TPE) and thermoplastic polyurethane (TPU) offer excellent shock absorption and deformation, providing effective cushioning and reducing the damage caused by tooth damage. Furthermore, the soft rubber layer 2 provides a pleasant tactile feel, ensuring comfortable contact with the mouth without irritating the gums or oral tissues. Furthermore, it maintains good performance even under prolonged use and frequent friction.

[0143] Regarding the manufacturing process of the electric toothbrush head 100, in one embodiment, the electric toothbrush head 100 is manufactured by a beer injection molding process.

[0144] The overmolding process allows the electric toothbrush head 100 to be molded in one go, reducing production steps and assembly steps, improving production efficiency, and reducing production costs. Furthermore, it allows the hard rubber base and the soft rubber layer to be tightly bonded, preventing delamination or shedding during use and ensuring product quality and stability.

[0145] In another embodiment, the electric toothbrush head 100 is manufactured by a multi-color injection molding process, and the color of the brush plate 1 and the color of the soft rubber layer 2 are different from each other.

[0146] Through the multi-color injection molding process, not only can the molding of the electric toothbrush head 100 be completed in one go, reducing the production process and assembly links and improving production efficiency, but also because the color of the brush plate 1 is different from the color of the soft rubber layer 2, it is also beneficial to improve the aesthetics of the electric toothbrush head 100.

[0147] Example 2

[0148] The present application also provides an electric toothbrush, such as Figure 5 As shown, the electric toothbrush includes an electric toothbrush head 100, a handle 200 and a toothbrush driver (not shown in the figure). The toothbrush driver is provided on the handle 200, and the output shaft of the toothbrush driver is detachably connected to the electric toothbrush head 100, and the toothbrush driver is used to drive the electric toothbrush head 100 to move.

[0149] The electric toothbrush head 100 has the same structure as any of the electric toothbrush heads 100 in the above embodiments, and can bring the same or similar beneficial effects. For details, please refer to the description in the above embodiments, and this embodiment will not be repeated here.

[0150] In the present application, when the electric toothbrush head 100 accidentally collides with the teeth during use, not only can the soft rubber layer 2 reduce a certain amount of impact force, which is beneficial to reduce the discomfort and potential damage caused by teeth hitting to a certain extent, but more importantly, the buffering protrusion structure 4 protruding from the soft rubber layer 2 can first contact the teeth and deform to absorb most of the collision energy, thereby reducing the direct impact on the teeth, which is beneficial to further enhance the buffering effect, further reduce the discomfort and potential damage caused by teeth hitting, and further improve the user experience.

[0151] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some or all of the technical features therein.
