Abstract
Description
Technical Field
[0001] This disclosure pertains to the field of nursing devices, and specifically relates to a toothbrush head and a toothbrush. Background Technology
[0002] Toothbrushes are a core tool for maintaining oral health in daily life. They can clean the surface and gaps of teeth, reduce plaque buildup, and thus lower the risk of oral diseases. In addition, toothbrushes can also maintain gum health by gently massaging the gums while brushing, promoting blood circulation in the gums, and enhancing the resistance of gum tissue.
[0003] Because the surface of teeth is not a flat plane, the bristles of existing toothbrush heads cannot completely conform to the tooth surface, gaps between teeth, or gums. If force is applied to make the bristles completely conform, it is very easy to damage the teeth and scratch the gums. Utility Model Content

The first hair implantation piece has two tooth surface cleaning hair implantation holes symmetrically arranged above and below the minor axis of the elliptical hair implantation piece group. The upper end of the tooth surface cleaning hair implantation hole above the minor axis is provided with a tooth interdental cleaning hair implantation hole, and the lower end of the tooth surface cleaning hair implantation hole below the minor axis is provided with another tooth interdental cleaning hair implantation hole.
[0011] Each of the two tooth surface cleaning hair implantation holes has a connecting bone on both outer walls, and a corresponding second hair implantation piece is connected to it.
[0012] In one embodiment of this disclosure, the ratio of the length of the connecting bone to the minor axis length of the elliptical hair graft group is 1:7-4:7.
[0013] In one embodiment of this disclosure, the brush head further includes a soft adhesive that covers the back and sides of the first bristle patch and at least two second bristle patches, and is configured to fix the first bristle patch and at least two second bristle patches into an elliptical bristle patch group, and to cause the first bristle patch to elastically deform relative to the first bristle patch under external force.
[0014] In one embodiment of this disclosure, the first hair implantation piece and at least two second hair implantation pieces are arranged to form an elliptical hair implantation piece group. The major axis of the elliptical hair implantation piece group extends along the length direction of the brush handle. The first hair implantation piece has two tooth surface cleaning hair implantation holes symmetrically arranged above and below the minor axis of the elliptical hair implantation piece group. The upper end of the tooth surface cleaning hair implantation hole above the minor axis is provided with a tooth interdental cleaning hair implantation hole, and the lower end of the tooth surface cleaning hair implantation hole below the minor axis is provided with another tooth interdental cleaning hair implantation hole.
[0015] Each of the two tooth surface cleaning hair implantation holes has a corresponding second hair implantation piece on both sides, and the soft glue covers the back and sides of the first hair implantation piece and each of the second hair implantation pieces.
[0016] In one embodiment of this disclosure, the ratio of the gap distance between the second hair implant and the hair implantation hole on the tooth surface to the minor axis of the ellipse is 1:7-4:7.
[0017] In one embodiment of this disclosure, the first bristle patch and the brush handle are an integral structure.
[0018] In one embodiment of this disclosure, the second hair grafts on both sides are arranged symmetrically about the major axis of the elliptical hair graft group.
[0019] In one embodiment of this disclosure, the cleaning of the tooth surface pores includes:
[0020] A central hole, wherein the central hole is a regular polygonal hole;
[0021] Peripheral holes, a plurality of said peripheral holes forming a complete circle with said central hole as the center;
[0022] The interdental cleaning hair implantation hole is a fan-shaped ring with the center of the elliptical hair implantation patch group as the center, and the central angle corresponding to the fan-shaped ring is greater than 90°.

Second bristle implants with bristle implant holes for cleaning the gums are set at intervals on both sides of the first bristle implant. The second bristle implants on the left and right sides are set independently and are not fixedly connected to the first bristle implant. Therefore, when the user brushes his teeth, the second bristle implants on the sides can float relative to the first bristle implant, so that the brush head can conform to the gum curve while cleaning the tooth surface and adapt to the pressure requirements of different cleaning areas. The second bristle implants can gently clean the gums and avoid excessive friction. In addition, by setting the second bristle implants independently, the resonance noise of brushing teeth can also be reduced.

[0053] Toothbrushes are a core tool for maintaining oral health in daily life. They can clean the surface and gaps of teeth, reduce plaque buildup, and thus lower the risk of oral diseases. In addition, toothbrushes can also maintain gum health by gently massaging the gums while brushing, promoting blood circulation in the gums, and enhancing the resistance of gum tissue.
[0054] Because the surface of teeth is not a flat plane, the bristles of existing toothbrush heads cannot completely conform to the tooth surface, gaps between teeth, or gums. If force is applied to make the bristles completely conform, it is very easy to damage the teeth and scratch the gums.
[0055] Therefore, this disclosure provides a toothbrush head, which is disposed on the toothbrush handle. The brush head includes a first bristle implant and at least two second bristle implants. The first bristle implant has a tooth surface cleaning bristle implant hole and at least two interdental cleaning bristle implant holes disposed at the upper and lower ends of the tooth surface cleaning bristle implant hole. The at least two second bristle implants are disposed at intervals on the left and right sides of the first bristle implant, and each second bristle implant has at least one gingival cleaning bristle implant hole.
[0056] The toothbrush head disclosed herein cleans the tooth surface and interdental spaces by having a first bristle implant with pores for cleaning the tooth surface and pores for cleaning the interdental spaces. Second bristle implants with pores for cleaning the gums are spaced apart on both sides of the first bristle implant to clean the gums. The second bristle implants on both sides are independently positioned and not fixedly connected to the first bristle implant. Therefore, when the user brushes their teeth, the second bristle implants on the sides can float relative to the first bristle implant, allowing the brush head to conform to the gum line while cleaning the tooth surface and adapt to the pressure requirements of different cleaning areas. The second bristle implants can gently clean the gums, avoiding excessive friction. Furthermore, by independently positioning the second bristle implants, the resonance noise during brushing can be reduced.
[0057] Furthermore, this disclosure also provides a toothbrush including the brush head of this disclosure. The toothbrush of this disclosure can clean teeth and gums simultaneously, adapt to the pressure requirements of the tooth surface and gums in the oral cavity, avoid damage to the tooth surface, reduce irritation to the gums, thereby achieving targeted cleaning of different areas in the oral cavity and improving brushing efficiency.
[0058] For ease of understanding, please refer to the following: Figures 1 to 6 The toothbrush head and the specific structure and working principle of the toothbrush provided in this disclosure are described in detail with reference to the embodiments.
[0059] In one embodiment, the present disclosure provides a toothbrush head disposed on the toothbrush handle. The brush head includes a first bristle implant 10 and at least two second bristle implants 20. The first bristle implant 10 has tooth surface cleaning bristle implant holes 11 and at least two interdental cleaning bristle implant holes 12 disposed at the upper and lower ends of the tooth surface cleaning bristle implant holes 11. The at least two second bristle implants 20 are respectively disposed on the left and right sides of the first bristle implant 10 at intervals, and each second bristle implant 20 has at least one gingival cleaning bristle implant hole 21.
[0060] In detail, dental plaque is most likely to accumulate at the junction of teeth and gums and in the lower and middle areas of teeth, leading to gingivitis or periodontal disease. If users brush their teeth too hard to clean the gingival sulcus, the bristles can directly scratch the gum tissue, causing redness, swelling, and bleeding. Long-term vigorous friction can damage the elasticity of the gums, leading to gum recession. At the same time, excessive brushing can also cause microscopic scratches on the tooth surface, and long-term wear can form wedge-shaped defects on the teeth.
[0061] Therefore, the toothbrush head of this disclosure cleans the tooth surface and interdental spaces by providing a first bristle implant 10 with tooth surface cleaning bristle implant holes 11 and interdental cleaning bristle implant holes 12, and provides second bristle implant 20 with gingival cleaning bristle implant holes 21 on the left and right sides of the first bristle implant 10 at intervals to clean the gingiva. The second bristle implant 20 on the left and right sides is provided independently and is not fixedly connected to the first bristle implant 10.
[0062] When a user brushes their teeth, the second bristle pad 20 on the side can float relative to the first bristle pad 10. This allows it to closely conform to the natural curve of the gums while cleaning the tooth surface, and adapt to the pressure requirements of different cleaning areas. For harder areas of the tooth surface, it maintains a high cleaning force to remove plaque, while for sensitive areas such as the gum line and tooth root, the second bristle pad 20 can gently clean the gums and avoid excessive friction. In addition, by setting the second bristle pad 20 independently, the resonance noise between the first bristle pad 10 and the second bristle pad 20 of the brush head can also be reduced.
[0063] See Figure 2 and Figure 3In one embodiment of this disclosure, the second hair graft 20 is connected to the first hair graft 10 via a resilient connecting bone 3.
[0064] In detail, the second hair implant 20 is connected to the first hair implant 10 by an elastic connecting bone 3. The connecting bone 3 is a small, hard plastic structure that ensures the stability of the connection between the second hair implant 20 and the first hair implant 10. However, due to its small size, it still has a certain elastic deformation capacity, which allows the second hair implant 20 to move slightly while maintaining the connection between the first hair implant 10 and the second hair implant 20. Therefore, the connecting bone 3 can produce a certain deformation and angle change under the action of external force, so that the first hair implant 10 and the second hair implant 20 can better fit the teeth and gums. Thus, when brushing teeth, the stiff bristles of the second hair implant 20 on both sides can avoid directly pressing the gums, and the second hair implant 20 can absorb the pressure applied by the user, reduce the impact on the gums, avoid excessive friction on the gums, and thus reduce the stimulation of the gums.
[0065] See Figure 2 and Figure 3 In one embodiment of this disclosure, the first hair graft 10, the second hair graft 20, and the connecting bone 3 are integrally injection molded.
[0066] Specifically, injection molding is a technology that molds multiple parts or structures in one go through the injection molding process. It eliminates the need for traditional separate assembly, avoids the separation risk in traditional bonding processes, improves the impact resistance of the first bristle patch 10 and the second bristle patch 20, increases the service life of the brush head, and eliminates the problem of bacterial growth at traditional seams.
[0067] Furthermore, through injection molding, the relative positions of the first bristle implant 10, the second bristle implant 20, and the connecting bone 3 are accurate, avoiding slight displacement caused by loosening in traditional assembly processes. When the bristles are subjected to force, the force can be evenly transmitted to the first bristle implant 10 and the second bristle implant 20, rather than being concentrated in a single area. In addition, there are no seams at the connection between the connecting bone 3 and the bristle implant, avoiding stress concentration at the seams during brushing, which could lead to cracks or even fatigue fractures. This improves the stability of the connection between the first bristle implant 10 and the second bristle implant 20, enabling targeted cleaning of different areas of the teeth. The independently partitioned second bristle implant 20 will not shift or even separate from the first bristle implant 10 after long-term use, causing the bristles at the gum cleaning bristle implant hole 21 to fail and the brush head to be damaged.
[0068] See Figure 2 and Figure 6In one embodiment of this disclosure, a first hair implant 10 and at least two second hair implants 20 are arranged to form an elliptical hair implant group. The long axis of the elliptical hair implant group extends along the length of the brush handle. The first hair implant 10 has two tooth surface cleaning hair implant holes 11 symmetrically arranged above and below the short axis of the elliptical hair implant group. The upper end of the tooth surface cleaning hair implant hole 11 above the short axis is provided with a tooth interdental cleaning hair implant hole 12, and the lower end of the tooth surface cleaning hair implant hole 11 below the short axis is provided with another tooth interdental cleaning hair implant hole 12. A connecting bone 3 is provided on each of the two outer walls of the tooth surface cleaning hair implant hole 11, and a corresponding second hair implant 20 is connected to it.
[0069] In detail, the first hair implant 10 and at least two second hair implants 20 are arranged to form an elliptical hair implant group. The long axis of the elliptical hair implant group extends along the length of the brush handle, adapting to the structure of the human oral cavity. The elliptical arc edge can naturally conform to the curvature of the tooth arrangement, reducing mechanical friction on the buccal mucosa and gums. The long axis of the elliptical hair implant group coincides with the direction of the tooth row and can cover the surface of 2-3 teeth at one time, improving cleaning efficiency. The narrow design in the short axis direction can reach deep into the posterior tooth area, reducing cleaning dead corners and avoiding collision with the inner cheek mucosa. When cleaning the posterior tooth area, the arc-shaped end of the elliptical hair implant group will not scratch the mucosa. Furthermore, in the one-piece injection molding process of the hair implant, the elliptical mold cavity is streamlined, and the flow resistance of the molten material during injection is lower than that of the square mold.
[0070] Furthermore, the first bristle implant 10 has two tooth surface cleaning bristle implant holes 11 symmetrically arranged above and below the short axis of the elliptical bristle implant group. The symmetrical design makes the pressure difference of the bristles on the surface of adjacent teeth smaller, avoiding over-cleaning of one side of the teeth and increasing the risk of wear, or insufficient cleaning of the other side of the teeth. In addition, it helps to balance the center of gravity of the toothbrush head and avoids irregular shaking of the brush head in the mouth or noise caused by uneven weight distribution.
[0071] The upper end of the tooth surface cleaning implant 11 above the short axis is provided with a tooth interdental cleaning implant 12, and the lower end of the tooth surface cleaning implant 11 below the short axis is provided with another tooth interdental cleaning implant 12. In this way, when the user cleans the tooth surface through the bristles of the tooth surface cleaning implant 11, the bristles of the tooth interdental cleaning implant 12 at both ends can simultaneously extend into the adjacent tooth gaps and clean them. When brushing, the bristles penetrate deep into the tooth gaps to clean food residue, thus improving the cleaning efficiency of the toothbrush.
[0072] Each of the two tooth surface cleaning pilosula 11 has a connecting bone 3 on its outer side and a corresponding second pilosula 20 connected to it. The second pilosula 20 on the side can float relative to the first pilosula 10. While cleaning the tooth surface, it can closely fit the natural curve of the gum and adapt to the pressure requirements of different cleaning areas. The bristle tip in the gingival cleaning pilosula 21 of the second pilosula 20 can directly penetrate into the gingival sulcus in the corresponding direction, cover the junction of the tooth and gum, remove the attached plaque, and make the contact between the bristles and the tooth surface more uniform, avoiding excessive local friction and reducing the risk of enamel wear.
[0073] See Figure 2 and Figure 3 In one embodiment of this disclosure, the ratio of the length of the connecting bone 3 to the short axis length of the elliptical hair graft group is 1:7-4:7.
[0074] In this way, the ratio of the length of the connecting bone 3 to the short axis length of the elliptical hair graft group is set to 1:7-4:7, which can provide a buffer gap so that the independently set second hair graft 20 has enough space to float relative to the fixed first hair graft 10, adapting to the pressure requirements of the gingival area. In addition, the length of the connecting bone 3 will not be too long, so that it is easy to crack under the applied pressure, or even cause the second hair graft 20 to fall off.
[0075] Furthermore, a buffer gap is provided between the first bristle pad 10 and the second bristle pad 20 to distribute the pressure during brushing and prevent excessive friction of the bristles on the teeth or gums, so that the brush head of this disclosure can clean the teeth and gums in a targeted manner. Moreover, human teeth are not completely straight, but are arranged in an arc shape. The bristles of the dense tooth surface cleaning bristle pores 11 fit the teeth, while the gaps on both sides allow the bristles to adapt more flexibly to the natural curvature of the teeth.
[0076] Based on this, in one embodiment of the present disclosure, the back and sides of the first hair implant 10 and at least two second hair implants 20 are further provided with soft adhesive 4 to cover the first hair implant 10, the second hair implants 20 and the connecting bone 3, forming a transition area at the edge of the brush head, reducing the impact stimulation of the brush head on the oral mucosa, absorbing the energy of the toothbrush vibration, and reducing the intensity of the vibration transmitted to the hand.
[0077] See Figure 1 and Figure 6 In one embodiment of this disclosure, the brush head further includes a soft rubber 4, which covers the back and sides of the first bristle patch 10 and at least two second bristle patches 20, and is configured to fix the first bristle patch 10 and at least two second bristle patches 20 into an elliptical bristle patch group, and to cause the first bristle patch 10 to undergo elastic deformation relative to the first bristle patch 10 under external force.
[0078] In detail, soft rubber 4 is a flexible material that feels soft to the touch at room temperature and does not require vulcanization, and is usually injection molded. Its characteristics include low surface hardness, good flexibility, and malleability.
[0079] Combination Figure 5 The back of the two tooth surfaces of the first hair implant 10 are respectively provided with positioning posts. When the soft glue 4 covers the back and sides of the first hair implant 10 and at least two second hair implants 20, the positioning posts restrict the displacement of the soft glue 4 in the lateral direction, preventing the soft glue 4 from shifting laterally with the rotation of the first hair implant 10.
[0080] See Figure 4 and Figure 6 In one embodiment of this disclosure, a first hair implant 10 and at least two second hair implants 20 are arranged to form an elliptical hair implant group. The long axis of the elliptical hair implant group extends along the length of the brush handle. The first hair implant 10 has two tooth surface cleaning hair implant holes 11 symmetrically arranged above and below the short axis of the elliptical hair implant group. The upper end of the tooth surface cleaning hair implant hole 11 above the short axis is provided with a tooth interdental cleaning hair implant hole 12, and the lower end of the tooth surface cleaning hair implant hole 11 below the short axis is provided with another tooth interdental cleaning hair implant hole 12. A corresponding second hair implant 20 is provided on both sides of the two tooth surface cleaning hair implant holes 11. Soft glue 4 covers the back and sides of the first hair implant 10 and each second hair implant 20.
[0081] In detail, the first bristle implant 10 and at least two second bristle implants 20 are arranged to form an elliptical bristle implant group. The long axis of the elliptical bristle implant group extends along the length of the brush handle, adapting to the structure of the human oral cavity and improving cleaning efficiency.
[0082] Furthermore, the first bristle implant 10 has two tooth surface cleaning bristle implant holes 11 symmetrically arranged above and below the short axis of the elliptical bristle implant group. The symmetrical design makes the pressure difference of the bristles on the surface of adjacent teeth smaller, avoiding over-cleaning of one side of the teeth and increasing the risk of wear, or insufficient cleaning of the other side of the teeth. In addition, it helps to balance the center of gravity of the toothbrush head and avoids irregular shaking of the brush head in the mouth or noise caused by uneven weight distribution.
[0083] The upper end of the tooth surface cleaning implant 11 above the short axis is provided with a tooth interdental cleaning implant 12, and the lower end of the tooth surface cleaning implant 11 below the short axis is provided with another tooth interdental cleaning implant 12. In this way, when the user cleans the tooth surface through the bristles of the tooth surface cleaning implant 11, the bristles of the tooth interdental cleaning implant 12 at both ends can simultaneously extend into the adjacent tooth gaps and clean them. When brushing, the bristles penetrate deep into the tooth gaps to clean food residue, thus improving the cleaning efficiency of the toothbrush.
[0084] Each of the two tooth surface cleaning hair implant holes 11 has a corresponding second hair implant 20 on both sides. Soft glue 4 covers the back and sides of the first hair implant 10 and each second hair implant 20. In this way, there is no connecting structure between the second hair implant 20 on the left and right sides and the first hair implant 10. The second hair implant 20 is supported only by the soft glue 4. The independently set second hair implant 20 has better floating ability, which can gently clean and massage the gums, and can also absorb the instantaneous impact force when brushing teeth accidentally, so as to avoid irritation to the gums.
[0085] Furthermore, the first bristle implant 10 is fixedly installed, so the force applied by the user can be transmitted stably without affecting the cleaning of the tooth surface and interdental spaces by the bristles in the tooth surface cleaning implant hole 11 and the interdental cleaning implant hole 12.
[0086] See Figure 4 and Figure 5 In one embodiment of this disclosure, the ratio of the gap distance between the second hair implant 20 and the tooth surface cleaning hair implant hole 11 to the minor axis of the ellipse is 1:7-4:7.
[0087] In this way, the ratio of the gap between the second hair implant 20 and the tooth surface cleaning hair implant hole 11 to the minor axis of the ellipse is set to 1:7-4:7, which can provide a buffer gap so that the independently set second hair implant 20 has enough space to float relative to the fixed first hair implant 10 to adapt to the pressure requirements of the gingival area. In addition, the gap distance is not too long, so that the second hair implant 20 is easy to fall off from the soft glue 4 after being subjected to applied pressure.
[0088] Furthermore, a buffer gap is provided between the first bristle pad 10 and the second bristle pad 20 to distribute the pressure during brushing and prevent excessive friction of the bristles on the teeth or gums, so that the brush head of this disclosure can clean the teeth and gums in a targeted manner. Moreover, human teeth are not completely straight, but are arranged in an arc shape. The bristles of the dense tooth surface cleaning bristle pores 11 fit the teeth, while the gaps on both sides allow the bristles to adapt more flexibly to the natural curvature of the teeth.
[0089] In one embodiment of this disclosure, the first bristle patch 10 and the brush handle are an integral structure.
[0090] In detail, the traditional separate connection between the bristle implant and the brush handle requires welding, bonding or mechanical fixation. After long-term use, the bristle implant may loosen or fall off. This disclosure sets the first bristle implant 10 and the brush handle as an integral structure, and eliminates the connection gap through the integral molding process, avoiding water accumulation and bacterial growth at the connection point. In addition, the integral structure eliminates the assembly steps of the first bristle implant 10 and the brush handle, reducing production steps and lowering costs.
[0091] See Figure 2 and Figure 4 In one embodiment of this disclosure, the second hair grafts 20 on both sides are arranged symmetrically about the major axis of the elliptical hair graft group.
[0092] Specifically, the oval-shaped bristle implants are small and conform to the curve of the human oral cavity. Their symmetrical arrangement about the long axis better adapts to the natural curvature of the tooth arrangement, improving cleaning coverage. When brushing, the brush head needs to move back and forth along the long axis. The bristles in the symmetrical gum cleaning implant holes 21 are evenly stressed during cleaning, avoiding excessive friction of the gums on one side and reducing the risk of gum bleeding or damage. In addition, it can reduce the risk of the brush head tilting due to uneven pressure on one side, which could lead to excessive penetration of the bristles on one side and scratch the gingival sulcus. Furthermore, when cleaning the posterior teeth, it can prevent the brush head from getting stuck deep in the oral cavity due to uneven force.
[0093] See Figure 2 and Figure 4 In one embodiment of this disclosure, the tooth surface cleaning hair implantation hole 11 includes a central hole and peripheral holes, wherein the central hole is a regular polygonal hole; a plurality of peripheral holes form a complete circle with the central hole as the center; the interdental cleaning hair implantation hole 12 is a fan-shaped ring with the center of the elliptical hair implantation patch as the center, and the central angle corresponding to the fan-shaped ring is greater than 90°; the cross-sectional profile of the gingival cleaning hair implantation hole 21 includes a first arc segment, a second arc segment, and a straight line segment, wherein the first arc segment is parallel to the complete circle formed by the peripheral holes; the second arc segment is a part of an ellipse; the straight line segment is parallel to the minor axis of the ellipse; the first arc segment and the second arc segment are connected by a smooth curve and a straight line segment.
[0094] In detail, the central hole of the tooth surface cleaning pore 11 is a regular polygonal hole, and several peripheral holes form a complete circle with the central hole as the center. In this way, the coverage area of the tooth surface cleaning pore 11 is large, and multiple teeth can be cleaned at one time when brushing. At the same time, a harder bristle can be used in this area to enhance the friction effect and clean the pigment deposits on the tooth surface. If the area is too small, the pressure will be concentrated on a small area of the tooth surface, which may lead to excessive wear of the local enamel.
[0095] Furthermore, the interdental cleaning hair implantation hole 12 is a fan-shaped ring with the center of the elliptical hair implantation patch group as the center, surrounding the tooth surface cleaning hair implantation hole 11 and adapting to the elliptical outer contour. In this way, the interdental cleaning hair implantation hole 12 can clean the interdental spaces between adjacent teeth and has sufficient hair implantation area. The bristles in this area can be made of fine and soft bristles, so as to penetrate deep into the interdental spaces and remove food debris and plaque.
[0096] Meanwhile, the cross-sectional contour of the gingival cleaning implant pore 21 is adapted to the tooth surface cleaning implant pore 11, the interdental cleaning implant pore 12, and the oval outer contour. The bristles in this area can be made of soft bristles. Combined with the independent floating structure of the gingival cleaning implant pore 21, it can gently touch the edge of the gums, which can clean the gingival sulcus without causing gum bleeding due to excessive pressure.
[0097] In one embodiment, the bristles implanted in the interdental cleaning bristle implant 12 and the gingival cleaning bristle implant 21 can be tilted outward relative to the center of the brush head, thereby being more suitable for cleaning interdental spaces and gingiva, improving cleaning efficiency, and reducing irritation to the gingiva. This disclosure does not impose any limitations.
[0098] On the other hand, this disclosure also provides a toothbrush, including a brush head, a handheld portion, and a handle, wherein the brush head is the brush head shown in any of the above embodiments; and the handle is configured to connect the brush head and the handheld portion.
[0099] In detail, the toothbrush of this disclosure has its brush head mounted on the handle via a brush head holder, and the handle is connected to the handheld part.
[0100] When using the toothbrush disclosed herein, after completing the pre-brushing preparations, the user holds the handle and brushes their teeth. During brushing, the bristles in the cleaning pores 11 of the first bristle plate 10 on the tooth surface rub against the outer surface of the teeth, cleaning the surface of 2-3 teeth. The bristles in the cleaning pores 12 at the upper and lower ends of the first bristle plate 10 naturally penetrate into the gaps between the teeth through slight vibration, removing food debris. At the same time, the second bristle plates 20, independently set on the left and right sides of the first bristle plate 10, clean the gums. The bristles in the gum cleaning pores 21 massage the gums and clean the gingival sulcus. This process is repeated until all teeth are cleaned.
[0101] Therefore, the toothbrush disclosed herein can clean teeth and gums simultaneously, adapting to the pressure requirements of the tooth surface and gums in the oral cavity, avoiding damage to the tooth surface, reducing irritation to the gums, thereby achieving targeted cleaning of different areas in the oral cavity and improving brushing efficiency.
[0102] The various embodiments of this disclosure have been described above. These descriptions are exemplary and not exhaustive, and are not limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is chosen to best explain the principles, practical application, or technical improvements to the embodiments in the market, or to enable others skilled in the art to understand the embodiments disclosed herein. The scope of this disclosure is defined by the appended claims.
