Abstract
Description
Technical Field
[0001] The present application relates to the technical field of toothbrushes, and in particular to a children's toothbrush. Background Art
[0002] In today's society, oral hygiene issues have gradually become the focus of consumers' attention, and toothbrush designs have also shown a trend of diversification. As we all know, a toothbrush is mainly composed of a handle and a brush head. Most of the common toothbrush handles on the market are straight-handled designs, but in actual use, this design is not ideal for cleaning dental plaque in the posterior molar area due to the limitations of the natural contours of the teeth. Especially for child users, since their fingers are not fully developed, especially the thumb's control ability is limited, they often use a gripping method when holding the toothbrush (that is, the thumb and the other four fingers form a fist). In this gripping state, when using a traditional straight-handled toothbrush, it is difficult for child users to flexibly adjust the angle of the brush head, especially when the teeth are arranged in an arc shape. This gripping method makes it difficult to ensure that the brush head fits closely to the tooth surface, resulting in a cleaning blind spot and affecting the cleaning effect.
[0003] Furthermore, children's oral skin is relatively delicate, so when using a toothbrush, the risk of the toothbrush piercing the mouth and gums, which could result from a child falling, must be prevented. To this end, the toothbrush handle should have a certain degree of grip reliability and elasticity, but this is a requirement that most toothbrush designs currently on the market struggle to meet. Utility Model Content
[0004] The purpose of the present utility model is to solve the above technical problems and provide a children's toothbrush. The children's toothbrush of the present application can better fit the curvature of teeth for cleaning, thereby improving the cleaning effect; and has a certain grip reliability.
[0005] In order to achieve the above-mentioned purpose, the technical solutions of the present utility model include:
[0006] A children's toothbrush comprises a brush head and a brush handle, wherein bristles are provided on the front side of the brush head, the radial dimension of the brush handle gradually decreases from the end toward the brush head, and the end of the brush handle is curved in an arc shape toward the brush head; and the arc curvature radius of the brush handle surface on the same side of the end of the brush handle as the bristles is smaller than that of the brush handle surface on the opposite side from the bristles, so that the brush handle has an asymmetric arc shape; the arc curvature of the brush handle end gradually decreases toward the brush head until the connecting section of the brush handle and the brush head is a straight section; an acute angle is formed between the surface formed by the connection between the top of the bristle side of the brush head and the end of the brush handle and the horizontal plane, and the angle range of the acute angle is 8-14 degrees.
[0007] In the present application, the brush handle is overall arc-shaped, and the radial dimension gradually decreases towards the brush head. While ensuring the structural strength, the brush handle has a certain elasticity due to the smaller size of the middle part, which makes the brush handle more comfortable when brushing teeth. The arc-shaped brush handle allows children to grasp it directly, and the grip is good. At the same time, due to the bending angle between the brush head and the brush handle, the brush head can better fit the contour of the teeth when grasped and used. The brush head can fit the posterior molar area more closely, with a better cleaning effect, and is more suitable for children.
[0008] In one embodiment, the acute angle is formed between the surface formed by connecting the apex of the bristle side of the brush head and the end mold clamping position of the brush handle and the horizontal plane.
[0009] In one embodiment, the acute angle is 11.4 degrees.
[0010] In one embodiment, the brush handle is composed of a brush handle body made of a hard material and a gripping sleeve made of a soft material, and the gripping sleeve is combined with the brush handle body by a secondary molding process.
[0011] In one embodiment, the gripping sleeve completely covers the brush handle body.
[0012] In one embodiment, the gripping sleeve half-covers the brush handle body, the brush handle body is exposed on the brush handle surface on the same side as the bristles, and the gripping sleeve covers the brush handle surface on the different side from the bristles and extends to the rear side of the brush head; the gripping sleeve is flush with the connection transition between the brush handle body and the brush handle body.
[0013] In one embodiment, in the area of the brush handle covered by the grip sleeve, the brush handle body is provided with a plurality of positioning protrusions.
[0014] In one embodiment, the positioning protrusion penetrates the grip sleeve and is higher than or flush with the plane of the grip sleeve, so that the grip sleeve can be quickly positioned and installed during processing and is not easy to fall off.
[0015] In one embodiment, a limiting protrusion extends from the bottom of the front side of the brush handle; a plurality of gripping protrusions are arranged at intervals in the vertical direction on the rear side of the brush handle; and the gripping protrusions are arc-shaped.
[0016] In one embodiment, the brush handle is provided with a plurality of wavy grooves at positions on the front side corresponding to the gripping protrusions. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] An embodiment of the present application provides a children's toothbrush, which is used to solve the technical problem that when the teeth are arranged in an arc shape, this gripping method makes it difficult to ensure that the brush head fits tightly against the tooth surface, thereby causing cleaning blind spots and affecting the cleaning effect.
[0022] In order to make the purpose, features, and advantages of the invention of this application more obvious and easy to understand, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the embodiments described below are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.
[0023] See also Figures 1 to 4 The embodiment of the present application provides a children's toothbrush, including a brush head 100 and a brush handle 200, wherein bristles 110 are provided on the front side of the brush head 100, and the radial dimension of the brush handle 200 gradually decreases from the end toward the brush head 100, and the end of the brush handle 200 is curved toward the brush head 110; and the arc bending radius of the brush handle surface on the same side of the end of the brush handle 200 as the bristles 110 is smaller than that of the brush handle surface on the different side from the bristles, so that the brush handle 200 is an asymmetric arc shape; the arc bending of the end of the brush handle 200 gradually decreases toward the brush head until the connecting section of the brush handle 200 and the brush head 100 is a straight line segment; an acute angle is formed between the surface formed by the connection between the top of the bristle side of the brush head 100 and the end of the brush handle 200 and the horizontal plane, and the angle range of the acute angle α is 8-14 degrees.
[0024] Specifically, bristles 110 are provided on the front side of the brush head 100, and a brush handle 200 is connected to the lower end. The brush handle 200 gradually increases downward from the connection with the brush head 100. The diameter of the brush handle 200 is relatively large at the gripping part, which has a better grip. At the same time, due to the smaller diameter close to the brush head, the brush handle has a certain elasticity and can produce a certain deformation when bent under force; the brush handle 200 is an arc shape that is concave toward the rear side of the brush head 100, and the arc-shaped brush handle is an asymmetric arc, with a smaller arc near the brush head side, which is better connected to the brush head; wherein, the surface formed by the top of the side wall on the bristle side of the brush head 100 and the end of the brush handle 200 forms an acute angle a with the horizontal plane, and the angle range of the acute angle α The angle of the brush handle 200 is 8 to 14 degrees; further, when the brush handle 200 is manufactured, the side wall of the brush handle 200 has a mold line due to the mold closing, and an acute angle α is formed between the plane formed by the vertex A on the bristle side of the brush head 100 and the mold closing position B at the end of the brush handle 200 and the horizontal plane. The acute angle α is preferably 11.4 degrees. Through reasonable angle restrictions, the curvature is prevented from being too large or too small, which affects the holding angle of the brush head and reduces the cleaning effect and holding experience of the posterior molar area. By setting an arc-shaped brush handle, children can directly grasp it when using it, and the bending angle of the brush head in the grasping state can better clean the posterior molar area, fit closely with the teeth, and improve the cleaning effect of dental plaque.
[0025] The brush handle is composed of a brush handle body 220 made of a hard material and a gripping sleeve 230 made of a soft material. The gripping sleeve 230 is combined with the brush handle body 220 by a secondary molding process. In this embodiment, the gripping sleeve 230 is made of TPE material to increase friction. The gripping sleeve 230 makes the brush handle 200 have a better gripping experience when gripping. Figure 3 The gripping sleeve 230 completely covers the brush handle body 220, so that the brush handle 200 has sufficient structural strength and is elastic when gripped, thereby improving the gripping experience.
[0026] See Figure 4 In another embodiment, the gripping sleeve 230 partially covers the handle body 220. The handle body 220 is exposed on the surface of the handle 200 on the same side as the bristles 110. The gripping sleeve 230 covers the surface of the handle 200 on the opposite side from the bristles 110 and extends to the rear side of the brush head 100. The gripping sleeve 230 is flush with the handle body 220 at the transition point. The bottom of the gripping sleeve 230 is an arc-shaped sleeve that fits over the bottom of the handle body 220. The handle body 220 has a corresponding groove corresponding to the gripping sleeve 230. The other end of the gripping sleeve 230 extends upward, gradually decreasing in size, and the end is attached to the rear side of the brush head 100. It is also extended with multiple protrusions to better clean the oral cavity. The gripping sleeve 230 is made of elastic material, making it difficult for children to grasp and use it, and the cleaning effect is good.
[0027] Furthermore, the handle body 220 is provided with several positioning bumps in the area covered by the gripping sleeve 230. These positioning bumps penetrate the gripping sleeve and are above or flush with the surface of the gripping sleeve. In this embodiment, the positioning bumps 222 on the left and right sides of the handle body 220 penetrate the gripping sleeve 230, with their end faces slightly protruding from the end faces of the gripping sleeve 230. This allows the gripping sleeve 230 to be quickly positioned and installed during processing, providing a more secure connection and increasing friction when gripping, making it less likely for the toothbrush to fall off.
[0028] Furthermore, a limit block 210 extends from the front of the handle 200, near the bottom. Several gripping blocks 231 are spaced vertically along the back of the handle. The limit block 210 extends forward from the bottom of the handle 200. The end surface of the limit block 210 is arc-shaped, allowing the hand to rest against the limit block 210 when gripping the toothbrush, preventing it from falling off. The gripping blocks 231 are also arc-shaped. The spacing between the multiple gripping blocks 231, arranged vertically along the arc of the handle 200, and their upper end surfaces create a contour that fits comfortably between fingers, enhancing grip stability.
[0029] Furthermore, the handle 200 has multiple wavy grooves 221 on the front side corresponding to the gripping protrusions 231. There is an area near the bottom of the front side of the handle body 220 that is not covered by the gripping cover 230. This area is where the tips of the fingers fit when holding the brush. The wavy grooves 221 increase friction, making it less likely to fall off during brushing.

Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and any modifications and variations of the present invention should also fall within the scope of protection of the claims of the present invention. In addition, although certain specific terms are used in this description, these terms are for convenience of description only and do not constitute any limitation to the present invention.
