Description

Technical Field

[0001] This utility model relates to the field of oral hygiene products, specifically a toothbrush. Background Technology

[0002] A dense toothbrush reduces pressure on the gums during brushing, thus improving brushing comfort. Reducing the spacing between bristle holes increases the area of ​​the bristle holes in the entire toothbrush head, thereby increasing the density of the bristle bundles and forming a denser toothbrush. However, current toothbrushes have round bristle holes, and the distance from the curved edge of the bristle hole to the curved edge of the adjacent bristle hole is not equal. Therefore, there is still a lot of space between the bristle holes that cannot be utilized, which makes it impossible to further increase the density of the bristle bundles. Utility Model Content

[0003] The purpose of this invention is to provide a toothbrush that solves the problem that the existing toothbrush has round bristle holes, resulting in a lot of unusable space between the bristle holes.

[0004] To solve the above problems, the present invention provides the following technical solution:

[0005] A toothbrush includes a toothbrush head and a toothbrush handle. The toothbrush head includes a base plate, and a plurality of bristle implantation holes are provided on one side of the base plate. The cross-section of each bristle implantation hole is square, and the side length of each bristle implantation hole is parallel and aligned with the side length of the adjacent bristle implantation hole. The side length of the bristle implantation hole is 2.2 mm to 3.2 mm. The minimum spacing between adjacent bristle implantation holes in the length direction of the base plate is ≥0.8 mm, and the minimum spacing between adjacent bristle implantation holes in the width direction of the base plate is ≥0.5 mm.

[0006] As described above, in a toothbrush, a metal plate for fixing the bristle bundle is provided in the bristle implantation hole. The angle between the length direction of the metal plate and the length direction of the substrate is 5° to 30°, and the length of the metal plate is greater than the side length of the bristle implantation hole + 0.5 mm.

[0007] In the toothbrush described above, the angle between the length direction of the metal sheet and the length direction of the substrate is 15°, the side length of the bristle implantation hole is 2.7 mm, and the length of the metal sheet is greater than 3.2 mm.

[0008] In the toothbrush described above, the length of the metal strip is 3.6 mm.

[0009] In the toothbrush described above, the depth of the bristle pores is 4.0 mm to 4.5 mm.

[0010] In the toothbrush described above, the depth of the bristle pores is 4.3 mm.

[0011] In the toothbrush described above, the distance between adjacent bristle holes in the length direction of the substrate is 1.0 mm, and the distance between adjacent bristle holes in the width direction of the substrate is 0.8 mm.

[0012] In the toothbrush described above, the length of the substrate is 22 mm to 25 mm, and the width of the substrate is 14 mm to 16 mm.

[0013] As described above, the length of the substrate is 23 mm and the width of the substrate is 15.3 mm.

[0014] Compared with the prior art, the present invention has the following advantages:

[0015] The toothbrush provided by this utility model has a square cross-section for the bristle implantation holes, and the side length of each bristle implantation hole is parallel and aligned with the side length of the adjacent bristle implantation holes. This maximizes the use of the space between the bristle implantation holes, thereby maximizing the density of the bristle bundles. At the same time, since the minimum spacing between adjacent bristle implantation holes in the length direction of the substrate is ≥0.8mm and the minimum spacing between adjacent bristle implantation holes in the width direction of the substrate is ≥0.5mm, the hole walls of the bristle implantation holes have sufficient thickness and strength, effectively preventing the deformation of the bristle implantation holes or the bristles from fraying due to the compression of the bristle bundles in the bristle implantation holes.

[0019] 1. Substrate; 2. Embedding holes; 3. Metal sheet. Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see the appendix Figure 1This embodiment provides a toothbrush, including a toothbrush head and a toothbrush handle. The toothbrush head includes a substrate 1. A plurality of bristle implantation holes 2 are provided on one side of the substrate 1. The cross-section of the bristle implantation holes 2 is square. The side length of each bristle implantation hole 2 is parallel and aligned with the side length of the adjacent bristle implantation holes 2. The side length of the bristle implantation holes 2 is 2.2mm to 3.2mm. The minimum distance L1 between adjacent bristle implantation holes 2 in the length direction of the substrate 1 is ≥0.8mm, and the minimum distance L2 between adjacent bristle implantation holes 2 in the width direction of the substrate 1 is ≥0.5mm.

[0022] In this embodiment of the toothbrush, the cross-section of the bristle implantation hole 2 is square, and the side length of each bristle implantation hole 2 is parallel and aligned with the side length of the adjacent bristle implantation hole 2. This maximizes the utilization of the space between the bristle implantation holes 2, thereby maximizing the density of the bristle bundles. At the same time, since the minimum spacing L1 of adjacent bristle implantation holes 2 in the length direction of the substrate 1 is ≥0.8mm and the minimum spacing L2 of adjacent bristle implantation holes 2 in the width direction of the substrate 1 is ≥0.5mm, the hole wall of the bristle implantation hole 2 has sufficient thickness and strength, effectively preventing the bristle implantation hole 2 from deforming or the bristles from fraying due to the compression of the bristle bundles in the bristle implantation hole 2.

[0023] In this embodiment, the minimum spacing L2 of adjacent hair-planting holes 2 in the width direction of the substrate 1 must be ≥0.5mm to effectively prevent deformation of the hair-planting holes 2 or hair frizz caused by the bristle bundles being squeezed in the hair-planting holes 2 in the width direction of the substrate 1.

[0024] Furthermore, the bristle planting hole 2 is provided with a metal sheet 3 for fixing the bristle bundle. Since the metal sheet 3 is embedded from the length direction of the substrate 1, the minimum distance L1 between adjacent bristle planting holes 2 in the length direction of the substrate 1 is ≥0.8mm. On the one hand, this can prevent the bristle planting hole 2 from deforming or the bristles from splintering due to the bristle bundle being squeezed in the bristle planting hole 2 in the length direction of the substrate 1. On the other hand, it can effectively prevent the metal sheet 3 in the bristle planting hole 2 from touching the adjacent bristle planting hole 2 or touching the metal sheet 3 in the adjacent bristle planting hole 2.

[0025] Preferably, the distance L1 between adjacent hair-planting holes 2 in the length direction of the substrate 1 is 1.0 mm, and the distance L2 between adjacent hair-planting holes 2 in the width direction of the substrate 1 is 0.8 mm.

[0026] Furthermore, the angle θ formed between the length direction of the metal sheet 3 and the length direction of the substrate 1 is 5° to 30°. Compared with the embedding method where the metal sheet 3 is parallel to the length direction of the substrate 1, this embodiment adopts the embedding method where the metal sheet 3 forms an angle with the length direction of the substrate 1, which can minimize the spacing between adjacent hair-planting holes 2 in the length direction of the substrate 1.

[0027] Furthermore, the length L3 of the metal sheet 3 is greater than the side length of the hair implantation hole 2 + 0.5 mm, which ensures a stable connection between the metal sheet 3 and the hair implantation hole 2.

[0028] Preferably, the angle θ formed by the length direction of the metal sheet 3 and the length direction of the substrate 1 is 15°, the side length of the hair implantation hole 2 is 2.7mm, and the length L3 of the metal sheet 3 is greater than 3.2mm.

[0029] More preferably, the length L3 of the metal sheet 3 is 3.6 mm.

[0030] Furthermore, the depth of the hair implantation hole 2 is 4.0 mm to 4.5 mm. Specifically, to ensure the tension of the bristle bundles in the hair implantation hole 2, the depth of the hair implantation hole 2 needs to be ≥4.0 mm. Since the implantation depth of the metal sheet 3 is limited, and since the greater the depth of the hair implantation hole 2, the greater the thickness of the substrate 1 needs to be, an excessively thick substrate 1 will affect the user experience when brushing teeth and is not conducive to thorough cleaning. Therefore, to ensure the user experience, the depth of the hair implantation hole needs to be ≤4.5 mm.

[0031] More preferably, the depth of the hair implantation hole 2 is 4.3 mm.

[0032] Furthermore, increasing the length and width of the substrate 1 can increase the density of the bristle bundles. However, if the length and width of the substrate 1 are too large, it will affect the user experience when brushing teeth and will not be conducive to deep cleaning. Therefore, the length A of the substrate 1 is 22 mm to 25 mm, and the width B of the substrate 1 is 14 mm to 16 mm. The length A of the substrate 1 is the distance from the front end of the substrate 1 to the rear end of the last row of bristle holes 2, and the width B of the substrate 1 is the distance between the two sides of the substrate 1.

[0033] More preferably, the length A of the substrate 1 is 23 mm, and the width B of the substrate 1 is 15.3 mm.

These terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of this utility model, "first" information can also be referred to as "second" information, and similarly, "second" information can also be referred to as "first" information. In addition, the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0035] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
