[0001] The utility model relates to the technical field of daily necessities, in particular to an ultra-thin toothbrush head and a toothbrush with a gradually changing thickness. Background Art
[0002] A toothbrush is a daily necessity used in conjunction with toothpaste to clean the surface of teeth. It includes a handle, a toothbrush head provided at one end of the handle, and bristles provided on the toothbrush head. The existing toothbrush head has a relatively thick thickness, so it is difficult to clean narrow and hidden areas inside the oral cavity, such as the wisdom tooth area and the interdental area. Moreover, the toothbrush head with this thickness will cause compression and friction to the gums, damaging the gum health. If the thickness of the toothbrush head is reduced, in order to meet the strength requirements, strict requirements are imposed on materials and processes, which is not conducive to production and manufacturing. Summary of the Utility Model
[0003] The purpose of the utility model is to provide an ultra-thin toothbrush head with a gradually changing thickness to solve the problems that the existing toothbrush head has a relatively thick thickness, is difficult to clean narrow and hidden areas in the oral cavity, and causes compression and friction to the gums, damaging the gum health.
[0004] The utility model is realized by the following technical solutions:
[0005] The ultra-thin toothbrush head with a gradually changing thickness includes a body provided at one end of a toothbrush handle and bristles provided on the body. The end of the body connected to the toothbrush handle is defined as the lower end. The body has two opposite front and rear mounting surfaces, and the bristles are arranged on any one of the mounting surfaces. Among the two mounting surfaces, one mounting surface extends obliquely upward in the direction of the other mounting surface. The value range of the distance between the upper ends of the two mounting surfaces is: 2.0 mm to 3.5 mm, and the value range of the distance between the lower ends of the two mounting surfaces is: 4.0 mm to 5.5 mm.
[0006] Further, among the two mounting surfaces, the mounting surface that extends obliquely upward in the direction of the other mounting surface is defined as the rear end surface, and the other mounting surface is defined as the front end surface. The value range of the included angle θ between the rear end surface and the front end surface is: 2° to 4°.
[0007] Further, the bristles are arranged on the front end surface.
[0008] Further, the distance between the upper ends of the two mounting surfaces is 2.5 mm, and the distance between the lower ends of the two mounting surfaces is 4.0 mm.
[0009] Further, the body has two side surfaces oppositely arranged on the left and right sides of the mounting surface, and the two side surfaces are parallel to each other.
[0010] Further, the body has a top surface and a bottom surface that are oppositely arranged on the upper and lower sides of the mounting surface. The top surface is an arc surface that gradually transitions with the two side surfaces, and the bottom surface is an arc surface that gradually transitions with the two side surfaces.
[0011] Further, the top surface is concentrically arranged with a circle having the midpoint of the line connecting the two side surfaces as the radius.
[0012] Further, the top surface, the bottom surface and the two side surfaces constitute the outer peripheral surface of the body, and the outer peripheral surface gradually transitions with the two mounting surfaces to form a chamfer.
[0013] In order to solve the problems that the existing toothbrush head is relatively thick, it is difficult to clean the narrow and hidden areas of the oral cavity, and it causes compression and friction to the gums, damaging the gum health, the present utility model provides an ultra-thin toothbrush head with a gradually changing thickness. Correspondingly, a toothbrush is provided, including a handle and a toothbrush head provided on the handle, and the toothbrush head is the above-mentioned ultra-thin toothbrush head with a gradually changing thickness.
[0014] The advantages of this technical solution are that by configuring the body to have two mounting surfaces with a gradually narrowing distance from bottom to top, the thickness of the body is gradually narrowed from 4.0 mm to 5.5 mm to 2.0 mm to 3.5 mm from bottom to top. Since the thickness of the body is distributed with a thinner upper part and a thicker lower part, the front end of the toothbrush head can extend into the narrow and hidden areas to clean the wisdom teeth and tooth gap parts, and will not cause compression and friction to the gums in the narrow and hidden areas, realizing large-range non-destructive cleaning; and because the thickness of the body gradually narrows from bottom to top, compared with the toothbrush head structure with an overall narrowing, it has good structural strength, has low requirements for materials and processes, and has low production difficulty.

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.
[0023] Embodiment: As Figures 1-5 shown, the toothbrush includes a handle 1 and a brush head 2 provided on the handle 1. The brush head 2 is an ultra-thin toothbrush head with a gradually changing thickness. The ultra-thin toothbrush head with a gradually changing thickness includes a body 201 provided at one end of the handle 1 and bristles 202 provided on the body 201. One end of the body 201 connected to the toothbrush handle 1 is defined as the lower end. The body 201 has two front and rear opposite mounting surfaces 203. The bristles 202 are arranged on any one of the mounting surfaces 203. Among the two mounting surfaces 203, one mounting surface 203 extends obliquely upward in the direction of the other mounting surface 203. The value range of the upper end spacing H2 between the two mounting surfaces 203 is: 2.0 mm to 3.5 mm, and the value range of the lower end spacing H1 between the two mounting surfaces 203 is: 4.0 mm to 5.5 mm. Preferably, the upper end spacing between the two mounting surfaces 203 is 2.5 mm, and the lower end spacing between the two mounting surfaces 203 is 4.0 mm. The present invention provides a toothbrush with an ultra-thin toothbrush head having a gradually changing thickness to solve the problems that the existing toothbrush head is relatively thick, difficult to clean the narrow and hidden areas of the oral cavity, and causes compression and friction to the gums, damaging the gum health. The main solution is to configure the body 201 to have two mounting surfaces 203 with a gradually narrowing spacing from bottom to top, so that the thickness of the body 201 gradually narrows from 4.0 mm to 5.5 mm from bottom to top to 2.0 mm to 3.5 mm. Since the thickness of the body 201 is distributed with a thinner upper part and a thicker lower part, the front end of the brush head 2 can extend into the narrow and hidden areas to clean the wisdom teeth and tooth gap parts, and will not cause compression and friction to the gums in the narrow and hidden areas, realizing large-range damage-free cleaning; and because the thickness of the body 201 gradually narrows from bottom to top, compared with the brush head structure with an overall narrowing, it has good structural strength, has low requirements for materials and processes, and has low production difficulty.
[0024] In the embodiment of the present utility model, among the two mounting surfaces 203, the mounting surface 203 that extends obliquely upward toward the other mounting surface 203 is defined as the rear end surface 204, and the other mounting surface 203 is defined as the front end surface 205. The value range of the included angle θ between the rear end surface 204 and the front end surface 205 is: 2° to 4°. Preferably, the included angle θ between the rear end surface 204 and the front end surface 205 is 3°. The above setting configures the angle θ of the forward inclination of the rear end surface 204 to be 2° to 4°, that is, the thickness of the main body 201 gradually narrows from bottom to top, realizing the cleaning of narrow and hidden areas, and the gradual change of the thickness of the main body 201 is slow, with good use comfort.
[0025] In the embodiment of the present utility model, the bristles 202 are arranged on the front end surface 205. Since the bristles 202 are arranged on the front end surface 205, when in use, the front end surface 205 provided with the bristles 202 is approximately parallel to the tooth surface to be brushed, and the rear end surface 204 facing away from the tooth surface to be brushed abuts against the narrow and hidden area and the oral cavity, with good use comfort.
[0026] In the embodiment of the present utility model, the main body 201 has two side surfaces 206 oppositely arranged on the left and right sides of the mounting surface 203, and the two side surfaces 206 are parallel to each other. Since the main body 201 has two side surfaces 206 that are oppositely arranged on the left and right sides of the mounting surface 203 and are parallel to each other, the main body 201 is designed to have the same width in the left and right directions, with good structural strength.
[0027] In the embodiment of the present utility model, the main body 201 has a top surface 207 and a bottom surface 208 that are oppositely arranged on the upper and lower sides of the mounting surface 203. The top surface 207 is an arc surface that gradually transitions with the two side surfaces 206, and the bottom surface 208 is an arc surface that gradually transitions with the two side surfaces 206. Since the main body 201 has a top surface 207 and a bottom surface 208 that are oppositely arranged and gradually transition with the two side surfaces 206 respectively, stress concentration at the connection between the top surface 207, the bottom surface 208 and the two side surfaces 206 is avoided, enhancing its bending resistance and anti-deformation ability, and the structural strength is good.
[0028] In the embodiment of the present utility model, the top surface 207 is concentrically arranged with a circle with the midpoint of the connection line of the two side surfaces 206 as the radius. The above setting makes the transition between the top surface 207 and the two side surfaces 206 gentle and avoids stress concentration.
[0029] In the embodiment of the present utility model, the top surface 207, the bottom surface 208 and the two side surfaces 206 constitute the outer peripheral surface of the main body 201, and the outer peripheral surface and the two mounting surfaces 203 gradually transition to form a chamfer. Since the outer peripheral surface and the two mounting surfaces 203 gradually transition to form a chamfer, stress concentration at the connection between the outer peripheral surface and the two side surfaces 206 is avoided, enhancing its bending resistance and anti-deformation ability, and the structural strength is good.
[0030] In the embodiment of the present utility model, the brush head 2 and the handle 1 are integrally formed, and a transition surface (not marked in the figure) is formed by a slow transition at the connection between the handle 1 and the brush head 2. Since the brush head 2 and the handle 1 are integrally formed, the processing steps are reduced and the production efficiency is high.
[0031] It should be understood that in the present utility model, terms such as "first" and "second" are used to describe various information, but this information should not be limited to these terms. These terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of the present utility model, the "first" information can also be referred to as the "second" information, and similarly, the "second" information can also be referred to as the "first" information. In addition, the orientation or positional relationship indicated by terms such as "center of the circle", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.
[0032] As described above, one or more embodiments are provided in combination with specific content, and it is not determined that the specific implementation of the present utility model is only limited to these descriptions. Any approximation, similarity to the method, structure, etc. of the present utility model, or several technical deductions or substitutions made under the premise of the concept of the present utility model should be regarded as within the protection scope of the present utility model.
