Description

A toothbrush head Technical Field

[0001] This utility model relates to the field of cleaning products technology, and in particular to a toothbrush head. Background Technology

[0002] As living standards continue to improve, people have higher requirements for toothbrushes. Toothbrushes have also been upgraded from traditional manual toothbrushes to electric toothbrushes. Electric toothbrushes can improve the cleaning effect of the toothbrush head by applying high-frequency vibration to the toothbrush head or making the toothbrush head reciprocate at high speed through the motor.

[0003] To improve cleaning effectiveness, existing toothbrush heads typically feature angled bristles. These angled bristles can clean dirt from crevices at different angles. While this improves cleaning efficiency, the angle of the bristles is usually fixed, which may not suit everyone's needs. Therefore, there is a need for a toothbrush head that can change the angle of the bristles to accommodate different users' needs. Summary of the Invention

[0004] The purpose of this invention is to provide a toothbrush head that solves the problem that the tilt angle of the bristles in existing toothbrushes cannot be adjusted.

[0005] To achieve the above objectives, this utility model provides a toothbrush head, comprising a brush head body, an assembly cavity, and an tilting component. The tilting component includes a swing seat, which is mounted in the assembly cavity via a guide rod and is slidable on the guide rod. The swing seat has several sets of swing blocks, with a soft rubber key between each swing block and the swing seat. One end of the soft rubber key is engaged with the bottom of the swing block, and the other end is fixedly connected to the swing seat. Soft bristles are positioned above each swing block, and hinge posts are positioned on both sides of each swing block. A hinge seat is located in the assembly cavity, and the hinge posts are rotatable on the hinge seat. A sliding groove is located at the bottom of the assembly cavity, and a detachable slider switch is located at the bottom of the swing seat, allowing the slider switch to slide within the sliding groove.

[0006] Furthermore, a head mounting plate is provided on the brush head body, and the mounting plate is installed on the assembly cavity. The mounting plate is provided with a side brush part and an auxiliary part. The side brush part is located on the left and right sides of the soft brush bristles, and the auxiliary part is located at the front and rear ends of the soft brush bristles. The side brush part includes inclined inner brush bristles and outer brush bristles. The inner brush bristles are located on the side closer to the soft brush bristles, and the outer brush bristles are located on the side away from the soft brush bristles. The auxiliary part is provided with multiple sets of auxiliary brushes of different heights. The mounting plate is provided with an opening for the soft brush bristles to pass through.

[0007] Furthermore, a waterproof pad is provided on the mounting plate, which is fixedly connected to the swing block. The waterproof pad is provided with multiple sets of slots for the auxiliary part and the side brush part to pass through.

[0008] Furthermore, a waterproof cover is provided at the bottom of the brush head body to cover the sliding switch.

[0009] Furthermore, the brush head body is provided with a connecting handle, and a quick-release port is provided at the end of the connecting handle away from the brush head body.

[0010] Furthermore, the soft bristles include long bristles and short bristles, which are arranged alternately, with a length ratio of 4:5 between the long and short bristles.

[0011] The toothbrush head provided by this utility model allows users to adjust the tilt angle of the soft bristles by sliding a switch. The friction between the soft bristles and the groove allows the soft bristles to be positioned as needed, resulting in a tilted state that suits different users' preferences. At the same time, the tilted soft bristles can also change the direction of the force applied to the teeth, thereby improving the cleaning power of the toothbrush. Attached Figure Description

[0029] The present invention will be described in detail below with reference to specific embodiments.

[0030] In this utility model, unless otherwise explicitly specified and limited, when terms such as "set in," "connected," or "linked" appear, these terms should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or a connection through one or more intermediate media. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. The directional terms appearing in this utility model are for the purpose of better describing the characteristics of the features and the relationships between them. It should be understood that when the placement direction of this utility model changes, the direction of the characteristics of the features and the relationships between them also changes accordingly. Therefore, directional terms do not constitute an absolute limitation on the characteristics of the features and the relationships between them in space, but only a relative limitation.

[0031] As shown in Figures 1 to 6, this utility model provides a toothbrush head, which includes a brush head body 1, an assembly cavity 10 in the brush head body 1, an inclined component 2 in the assembly cavity 10, and an inclined component 2 including a swing seat 20. The swing seat 20 is installed in the assembly cavity 10 via a guide rod 24 and can slide on the guide rod 24. Several sets of swing blocks 21 are provided on the swing seat 20. A soft rubber key 26 is provided between the swing block 21 and the swing seat 20. One end of the soft rubber key 26 is stuck at the bottom of the swing block 21, and the other end of the soft rubber key 26 is fixedly connected to the swing seat 20. Soft bristles 23 are provided above the swing block 21. Hinge posts 22 are provided on both sides of the swing block 21. A hinge seat 11 is provided in the assembly cavity 10, and the hinge posts 22 can rotate on the hinge seat 11. A sliding groove is provided at the bottom of the assembly cavity 10, and a detachable sliding switch 25 is provided at the bottom of the swing seat 20. The sliding switch 25 can slide in the sliding groove.

[0032] With the above design, when the user needs to change the tilt angle of the soft bristles 23, the user only needs to push the sliding switch 25. The sliding switch 25 drives the swing seat 20 to slide in the assembly cavity 10. The sliding swing seat 20 will drive the swing block 21 to rotate around the center of the hinge seat 11 through the soft rubber key 26. The rotating swing block 21 will cause the soft bristles 23 to tilt. The tilted soft bristles 23 can change the direction of the force falling on the teeth, improving cleaning efficiency. The user can control the tilt angle of the soft bristles 23 by pushing the sliding switch 25 to adapt to the usage habits of different users. The sliding switch 25 can be locked in the groove by friction, increasing the difficulty of the sliding switch 25 sliding unnecessarily. At the same time, because the soft bristles 23 are relatively soft, the force when brushing teeth is difficult to change the tilt angle of the swing block 21 through the soft bristles 23, avoiding the change of the tilt angle of the soft bristles 23 during brushing, which would affect the cleaning efficiency.

[0033] In this embodiment, a head mounting plate 3 is provided on the brush head body 1. The mounting plate 3 is mounted on the assembly cavity 10. The mounting plate 3 is provided with a side brush part 5 and an auxiliary part 4. The side brush part 5 is located on the left and right sides of the soft brush bristles 23, and the auxiliary part 4 is located at the front and rear ends of the soft brush bristles 23. The side brush part 5 includes inclined inner brush bristles 50 and outer brush bristles 51. The inner brush bristles 50 are located on the side closer to the soft brush bristles 23, and the outer brush bristles 51 are located on the side away from the soft brush bristles 23. The auxiliary part 4 is provided with multiple sets of auxiliary brushes 40 of different heights. The mounting plate 3 is provided with an opening for the soft brush bristles 23 to pass through.

[0034] With the above design, the inclined inner bristles 50 and outer bristles 51 in the side brush part 5 can brush the root of the teeth from the side. The user can make the inner bristles 50 and outer bristles 51 brush the gaps between the teeth with a small swing angle, thus improving the cleaning efficiency of the toothbrush. The auxiliary brush 40 of the auxiliary part 4 can increase the brushing range and increase the brushing area.

[0035] In this embodiment, a waterproof pad 6 is provided on the mounting plate 3. The waterproof pad 6 is fixedly connected to the swing block 21. The waterproof pad 6 is provided with multiple sets of slots, which are used to pass through the auxiliary part 4 and the side brush part 5.

[0036] Through the above design scheme, the waterproof pad 6 can prevent water from entering the assembly cavity 10 and avoid the growth of bacteria inside the assembly cavity 10.

[0037] In this embodiment, a waterproof cover 7 is provided at the bottom of the brush head body 1, which is used to cover the sliding switch 25.

[0038] With the above design, the waterproof cover 7 at the bottom of the brush head body 1 can cover the slide groove, preventing water stains from entering the assembly cavity 10 through the slide groove. At the same time, the waterproof cover 7 itself has a certain elasticity, making it convenient for the user to push the sliding switch 25 through the waterproof cover 7.

[0039] In this embodiment, a connecting handle 8 is provided on the brush head body 1, and a quick-release port 9 is provided at the end of the connecting handle 8 away from the brush head body 1.

[0040] The quick-release port 9 on the handle 8 is used to connect to the electric toothbrush. Since the relevant design is existing technology and not an improvement of this utility model, it is not described in detail in this embodiment.

[0041] In this embodiment, the soft bristles 23 include long bristles 230 and short bristles 231, which are arranged alternately, and the length ratio of the long bristles 230 to the short bristles 231 is 4:5.

[0042] Through the above design, the alternating arrangement of long bristles 230 and short bristles 231 can improve the cleaning power of the toothbrush. When the user brushes their teeth, the long bristles 230 bend under force, and the short bristles 231 can just reach the teeth after the long bristles 230 bend. The alternating bending and straight bristles can improve the cleaning efficiency of hard-to-reach areas and improve the teeth cleaning effect.

[0043] The toothbrush head provided by this utility model allows the user to adjust the tilt angle of the soft bristles 23 by sliding the switch 25. The friction between the soft bristles 23 and the groove allows the soft bristles 23 to be locked in the desired position, making the soft bristles 23 tilted to suit the user's experience. At the same time, the tilted soft bristles 23 can also change the direction of the force applied to the teeth, thereby improving the cleaning power of the toothbrush.

[0044] Where there is no conflict, the above embodiments and features can be combined with each other.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
