Description

Technical Field

[0001] This utility model relates to the field of toothbrush technology, specifically to a children's oscillating brush head and toothbrush. Background Technology

[0002] Currently, the top surface of toothbrush bristles is usually made in a wavy or flat shape. This conventional bristle structure can effectively clean the flat tooth surface and the shallow areas between teeth, but it is difficult to effectively clean the gum line, molar grooves, and deep interdental gaps at the same time. Utility Model Content

[0003] In view of the shortcomings of the existing technology, this utility model aims to provide a children's swing-type brush head and toothbrush.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A children's swinging brush head includes a brush head body, wherein the front end of the brush head body is provided with a front row of bristle tufts, a middle row of bristle tufts and a rear row of bristle tufts from front to back.

[0006] The height of each row of bristles in the front row gradually increases from front to back, while the height of each row of bristles in the rear row gradually increases from back to front, thus forming a sloping surface in the front-to-back direction on the top surface of both the front and rear rows of bristles; the height of the last row of bristles in the front row and the first row of bristles in the rear row gradually increases from the left and right sides towards the middle, so that the tips of the last row of bristles in the front row and the first row of bristles in the rear row form an outwardly convex arc curve.

[0007] In the middle row of bristles, the height of each row of bristles gradually decreases from the middle forward and backward, and the height of the bristles in the same row gradually decreases from the left and right sides towards the middle.

[0008] Furthermore, each bristle in the front row of bristle clusters is inclined from front to back, and each bristle in the rear row of bristle clusters is inclined from back to front.

[0009] Furthermore, the height of the highest point of the front row of brush bristles and the rear row of brush bristles is higher than the height of the highest point of the middle row of brush bristles.

[0010] Furthermore, the angle between the inclined surface of the top surface of the front row of brush bristles and the axis of the front row of brush bristles, and the angle between the inclined surface of the top surface of the rear row of brush bristles and the axis of the rear row of brush bristles, are both 45°.

[0011] Furthermore, the top surface of the middle row of brush bristles is a concave arc shape in the left-right direction.

[0012] This utility model also provides a children's swing toothbrush, including a main unit and the above-mentioned brush head. The main unit is connected to the rear end of the brush head body of the brush head and can drive the brush head to swing left and right.

[0013] The beneficial effects of this utility model are as follows: through the improvement of the bristle structure of this utility model, it is possible to thoroughly and effectively clean the gum line, molar grooves, and deep crevices between teeth. Attached Figure Description

[0017] The present invention will be further described below with reference to the accompanying drawings. It should be noted that this embodiment is based on the present technical solution and provides detailed implementation methods and specific operation processes, but the protection scope of the present invention is not limited to this embodiment.

[0018] Example 1

[0019] This embodiment provides a child-friendly, oscillating brush head, such as... Figure 1 As shown in Figure 3, the brush head body 1 is provided with a front row of bristle tufts 2, a middle row of bristle tufts 3 and a rear row of bristle tufts 4 from front to back.

[0020] The height of each row of bristles in the front row bristle tuft 2 gradually increases from front to back, while the height of each row of bristles in the rear row bristle tuft 4 gradually increases from back to front. As a result, the top surfaces of both the front row bristle tuft 2 and the rear row bristle tuft 4 have a sloping surface 7 in the front-to-back direction. The height of the last row of bristles in the front row bristle tuft 2 and the first row of bristles in the rear row bristle tuft 4 gradually increases from the left and right sides towards the middle, so that the tips of the last row of bristles in the front row bristle tuft 2 and the first row of bristles in the rear row bristle tuft 4 form an outwardly convex arc curve 5.

[0021] In the middle row of bristle clusters 3, the height of each row of bristles gradually decreases from the middle forward and backward, and the height of the bristles in the same row gradually decreases from the left and right sides towards the middle.

[0022] In the aforementioned brush head, when the brush head is tilted inwards and outwards longitudinally, the convex three-dimensional arc curve 5 formed by the tips of the foremost bristles of the front row and the last bristles of the rear row can effectively conform to the gum line. When the brush head swings left and right in conjunction with the main unit, the arc-shaped bristles can more effectively clean stains at the gum line. In addition, the top of the middle row of bristles has pointed tips 6 on both sides. When the brush head is placed vertically on the top of the molar, the pointed tips 6 on both sides can penetrate into the groove of the molar. When the brush head swings left and right, a digging force is generated, and the pointed bristles dig back and forth in the groove of the molar, thereby deeply cleaning the groove of the molar.

[0023] In this embodiment, each bristle in the front row of bristles 2 is inclined from front to back, and each bristle in the rear row of bristles 4 is inclined from back to front. The front row of bristles 2, which is inclined from front to back, and the rear row of bristles 4, which is inclined from back to front, form an "eight" shape. This allows the brush head to clean the tooth surface laterally, while the sharp angles formed at the tips of the front and rear bristles can penetrate into the interdental spaces on both sides of the teeth. When the brush head moves left and right in conjunction with the main unit, it can perform deep cleaning of the interdental spaces.

[0024] In this embodiment, the height of the highest point of the front row of brush bristles 2 and the rear row of brush bristles 4 is higher than the height of the highest point of the middle row of brush bristles 3.

[0025] In this embodiment, the angle between the inclined surface of the top surface of the front row of brush bristles 2 and the axis of the front row of brush bristles 2, and the angle between the inclined surface of the top surface of the rear row of brush bristles 4 and the axis of the rear row of brush bristles 4, are both 45°.

[0026] In this embodiment, the top surface of the middle row of brush bristles 3 is a concave arc shape 8 in the left-right direction.

[0027] Example 2

[0028] This embodiment provides a children's oscillating toothbrush, including a main unit and the brush head described in Embodiment 1. The main unit is connected to the rear end of the brush head body and can drive the brush head to oscillate left and right.

[0029] For those skilled in the art, various corresponding changes and modifications can be made based on the above technical solutions and concepts, and all such changes and modifications should be included within the protection scope of the claims of this utility model.
