Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of toothbrushes, and in particular to a children's swinging brush head and a toothbrush. Background Art
[0002] Currently, the top surface of a toothbrush's bristles is usually made into a wavy or flat shape as a whole. This conventional structure of bristles can effectively clean the flat tooth surface and the shallow areas between the teeth, but it is difficult to effectively clean the gum margin, molar grooves, and deep gaps between teeth at the same time. Summary of the Invention
[0003] In view of the deficiencies in the prior art, the present invention aims to provide a children's swinging brush head and toothbrush.
[0004] In order to achieve the above object, the present invention adopts the following technical solutions:
[0005] A children's swinging brush head comprises a brush head body, wherein the front end of the brush head body is provided with a front row of bristle clusters, a middle row of bristle clusters and a rear row of bristle clusters in sequence from front to back;
[0006] The height of each row of bristles in the front row of bristle clusters gradually increases from front to back, and the height of each row of bristles in the rear row of bristle clusters gradually increases from rear to front, so that the top surfaces of the front row of bristle clusters and the rear row of bristle clusters both form inclined surfaces in the front-to-back direction; the height of the bristles in the last row of the front row of bristle clusters and the frontmost row of the rear row of bristle clusters both gradually increase from left and right sides to the middle, so that the top ends of the bristles in the last row of the front row of bristle clusters and the frontmost row of the rear row of bristle clusters both form outwardly convex arc curves;
[0007] In the middle row of bristle tufts, the height of each row of bristles decreases gradually from the middle toward the front and toward the back, and the height of the bristles in the same row decreases gradually from the left and right sides toward the middle.
[0008] Furthermore, each bristle in the front row of bristle tufts is inclined from front to back, and each bristle in the back row of bristle tufts is inclined from back to front.
[0009] Furthermore, the height of the highest point of the front row of bristle tufts and the rear row of bristle tufts is higher than the height of the highest point of the middle row of bristle tufts.
[0010] Furthermore, the angle between the inclined surface of the top surface of the front row of bristle tufts and the axis of the front row of bristle tufts and the angle between the inclined surface of the top surface of the rear row of bristle tufts and the axis of the rear row of bristle tufts are both 45°.
[0011] Furthermore, the top surface of the middle row of bristle tufts is in the shape of an inwardly concave arc in the left-right direction.
[0012] The present invention also provides a children's swinging toothbrush, comprising a main unit and the above-mentioned brush head, wherein 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 effect of the present invention is that through the improvement of the bristle structure of the present invention, the gum margin, molar grooves and deep interdental crevices can be cleaned deeply and effectively. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] Figure 3 This is a front schematic diagram of the middle row of bristle tufts in Example 1 of the present invention. DETAILED DESCRIPTION
[0017] The present invention will be further described below in conjunction with the accompanying drawings. It should be noted that this embodiment is based on the technical solution and provides a detailed implementation method and specific operation process, but the protection scope of the present invention is not limited to this embodiment.
[0018] Example 1
[0019] This embodiment provides a children's swinging brush head, such as Figure 1 As shown in Figure 3, it includes a brush head body 1, and the front end of the brush head body 1 is provided with a front row of bristle clusters 2, a middle row of bristle clusters 3 and a rear row of bristle clusters 4 in sequence from front to back;
[0020] The height of each row of bristles in the front row of bristle clusters 2 gradually increases from front to back, and the height of each row of bristles in the rear row of bristle clusters 4 gradually increases from back to front, so that the top surfaces of the front row of bristle clusters 2 and the rear row of bristle clusters 4 are both formed with inclined surfaces 7 in the front-to-back direction; the height of the bristles in the last row of the front row of bristle clusters 2 and the frontmost row of the rear row of bristle clusters 4 are both gradually increased from the left and right sides to the middle, so that the top ends of the bristles in the last row of the front row of bristle clusters 2 and the frontmost row of the rear row of bristle clusters 4 are both formed with outwardly convex arc curves 5;
[0021] In the middle row of bristle tufts 3, the height of each row of bristles decreases gradually from the middle toward the front and toward the back, and the height of the bristles in the same row decreases gradually from the left and right sides toward the middle.
[0022] In the aforementioned brush head, when the brush head is tilted longitudinally inward or outward, the outwardly convex three-dimensional arc 5 formed by the tips of the frontmost bristles of the front bristle tufts and the rearmost bristles of the rear bristle tufts effectively conforms to the gum margin. When the brush head is swung left and right in conjunction with the main unit, the bristles in the arc shape more effectively clean stains along the gum margin. Furthermore, pointed tips 6 are formed on the left and right sides of the tops of the middle row of bristle tufts. When the brush head is placed vertically on top of the molars, these pointed tips 6 can penetrate deeply into the grooves of the molars. When the brush head is swung left and right, a digging force is generated, causing the pointed bristles to dig back and forth in the grooves of the molars, thereby deeply cleaning the grooves.
[0023] In this embodiment, each bristle in the front row of bristle tufts 2 is tilted from front to back, and each bristle in the rear row of bristle tufts 4 is tilted from back to front. The front row of bristle tufts 2, which are tilted from front to back, and the rear row of bristle tufts 4, which are tilted from back to front, form an "eight" shape. This allows the brush head to clean the tooth surface horizontally while the sharp corners formed on the top of the front row of bristle tufts and the rear row of bristle tufts can penetrate deep into the gaps between the teeth on both sides. When the brush head swings left and right in conjunction with the main unit, it can deeply clean the gaps between the teeth.
[0024] In this embodiment, the height of the highest point of the front row of bristle tufts 2 and the rear row of bristle tufts 4 is higher than the height of the highest point of the middle row of bristle tufts 3 .
[0025] In this embodiment, the angle between the inclined surface of the top surface of the front row of bristle tufts 2 and the axis of the front row of bristle tufts 2 and the angle between the inclined surface of the top surface of the rear row of bristle tufts 4 and the axis of the rear row of bristle tufts 4 are both 45°.
[0026] In this embodiment, the top surface of the middle row of bristle tufts 3 is in the shape of an inwardly concave arc 8 in the left-right direction.
[0027] Example 2
[0028] This embodiment provides a children's swinging toothbrush, comprising a main unit and the brush head described in Example 1. 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.
[0029] Those skilled in the art can make various corresponding changes and modifications based on the above technical solutions and concepts, and all of these changes and modifications should be included in the protection scope of the claims of the present invention.
