Description

Technical Field

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

[0002] A toothbrush typically consists of a brush head and a handle, and is a commonly used oral hygiene tool. In recent years, large-pore bristle toothbrushes have become popular in the market. These toothbrushes have a higher concentration of bristles in each pore, making the bristles less prone to deformation during use. However, the high density of the bristles creates pressure on the pore walls, potentially leading to cracking. Utility Model Content

[0003] The purpose of this invention is to provide a toothbrush that solves the problem of cracking of the bristle pores caused by the pressure exerted by the bristle bundles on the pore wall in existing large-pore toothbrushes.

[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-embedding holes are provided on one side of the base plate. Each bristle-embedding hole contains a bristle bundle, and the cross-sectional area of ​​the bristle-embedding hole is 3.0 mm². 2 ~7.5mm 2 The minimum spacing between adjacent hair-planting holes is >0.6mm, and the minimum spacing between the hair-planting holes and the edge of the substrate is >1mm.

[0006] In the toothbrush described above, the minimum distance between the bristle implantation hole at the front end of the substrate and the edge of the substrate is >1.2mm.

[0007] In the toothbrush described above, the minimum spacing between adjacent bristle holes is 0.6 mm to 1.5 mm.

[0008] In the toothbrush described above, the cross-section of the bristle implantation hole is circular, and the diameter of the bristle implantation hole is 2.0mm to 3.0mm.

[0009] In the toothbrush described above, the depth of the bristle implantation holes is 3.5 mm to 4.3 mm.

[0010] In the toothbrush described above, the bristle bundles are pressed and fixed within the bristle implantation holes by a metal sheet, and the flexural modulus of the substrate is 1000MPa to 2300MPa.

[0011] In the toothbrush described above, the flexural modulus of the substrate is 1000 MPa to 2000 MPa.

[0012] In the toothbrush described above, the number of bristles in the bristle bundle is 60 to 230, and the bristle diameter is 0.10 mm to 0.18 mm.

[0013] As described above, the cross-section of the bristle implantation hole is circular, the diameter of the bristle implantation hole is 2.3mm to 2.7mm, the number of bristles in the bristle bundle is 94 to 177, and the bristle diameter is 0.10mm to 0.14mm.

[0014] In a toothbrush as described above, a portion of the bristle implantation holes are arranged in a circumferential array along the substrate to form an outer circumferential bristle implantation hole group, and another portion of the bristle implantation holes are located inside the outer circumferential bristle implantation hole group and arranged in a circumferential array along the substrate to form an inner circumferential bristle implantation hole group. The spacing between adjacent bristle implantation holes in the inner circumferential bristle implantation hole group is greater than the spacing between adjacent bristle implantation holes in the outer circumferential bristle implantation hole group.

[0015] Compared with the prior art, the present invention has the following advantages:

[0016] 1. The toothbrush provided by this utility model, by adjusting the cross-sectional area range of the bristle holes, adjusting the spacing between adjacent bristle holes, and adjusting the spacing between the bristle holes and the edge of the substrate, makes the wall of the bristle holes have sufficient thickness and strength to withstand the pressure from the bristle bundles and avoid the bristle holes from cracking.

[0017] 2. The toothbrush provided by this utility model increases the spacing between the bristle bundles in the middle area by increasing the spacing between the inner bristle holes, thereby reducing the aggregation between the bristle bundles, effectively reducing water stains and bacterial growth.

[0023] 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.

[0024] Please see the appendix Figure 1 To be continued Figure 2 This embodiment provides a toothbrush, including a toothbrush head 1 and a toothbrush handle 2. The toothbrush head 1 includes a substrate 11, and a plurality of bristle implantation holes 111 are provided on one side of the substrate 11. Each bristle implantation hole 111 contains a bristle bundle 12, and the cross-sectional area of ​​the bristle implantation hole 111 is 3.0 mm². 2 ~7.5mm 2 The minimum spacing between adjacent hair-planting holes 111 is >0.6mm, and the minimum spacing between the hair-planting holes 111 and the edge of the substrate 11 is >1mm.

[0025] In this embodiment, a toothbrush is designed to have sufficient thickness and strength in the bristle hole wall by adjusting the cross-sectional area of ​​the bristle hole 111, the spacing between adjacent bristle holes 111, and the spacing between the bristle hole 111 and the edge of the substrate 11. This allows the bristle hole wall to withstand the pressure from the bristle bundle 12 and prevent the bristle hole 111 from cracking.

[0026] Furthermore, to improve the user experience, the minimum distance between the bristle implantation hole 111 and the edge of the substrate 11 is 1.0mm to 1.5mm. If the minimum distance between the bristle implantation hole 111 and the edge of the substrate 11 is greater than 1.5mm, the brushing sensation will worsen as the distance increases, resulting in a reduced user experience. Therefore, preferably, the minimum distance between the bristle implantation hole 111 and the edge of the substrate 11 is 1.0mm to 1.5mm.

[0027] Furthermore, since the hair implantation hole 111 located at the front end of the substrate 11 is more prone to cracking under pressure than hair implantation holes 111 located at other positions, in order to avoid the hair implantation hole 111 located at the front end of the substrate 11 cracking, the minimum distance L3 between the hair implantation hole 111 located at the front end of the substrate 11 and the edge of the substrate 11 is greater than 1.2 mm.

[0028] Furthermore, in order to improve the user experience, preferably, the minimum distance L3 between the hair-planting hole 111 at the front end of the substrate 11 and the edge of the substrate 11 is 1.2mm to 1.5mm.

[0029] Furthermore, to improve the user experience, the minimum spacing between adjacent bristle holes 111 is 0.6mm to 1.5mm. If the spacing between adjacent bristle holes 111 exceeds 1.5mm, the area of ​​the bristle holes 111 on the substrate 11 will be smaller, meaning the bristle bundles 12 will occupy a smaller proportion of the entire toothbrush head, reducing the user experience. Therefore, preferably, the minimum spacing between adjacent bristle holes 111 is 0.6mm to 1.5mm.

[0030] Furthermore, in order to more firmly fix the bristle bundle 12 in the bristle implantation hole 111, the depth of the bristle implantation hole 111 is 3.5mm to 4.3mm.

[0031] Furthermore, to ensure a more secure implantation of the metal sheet and bristle bundle 12 into the bristle implantation hole 111 and to prevent cracking of the hole, the bristle bundle 12 is pressed and fixed within the hole by the metal sheet. The flexural modulus of the substrate 11 is 1000 MPa to 2300 MPa. Specifically, the bristles of the bristle bundle 12 are folded in half by the metal sheet and thus embedded into the hole 111. Since the metal sheet exerts a certain force on the hole 111 when embedded, a higher flexural modulus means a harder substrate material, resulting in a more secure embedding of the metal sheet. If the flexural modulus is below 1000 MPa, the metal sheet is not securely embedded in the hole 111, which can easily lead to the bristle bundle 12 falling off. However, as the flexural modulus of the material increases, the material's flexibility decreases, meaning the material becomes more brittle. If the flexural modulus exceeds 2300 MPa, the bristle bundle 12 is prone to tearing the bristle hole 111 when it is inserted into the bristle hole. At the same time, when the metal sheet is embedded in the bristle hole 111, the material is subjected to the force of the metal sheet, which can easily cause the bristle hole 111 to crack.

[0032] To further avoid cracking of the pores 111, preferably, the bending modulus of the substrate 11 is 1000MPa to 2000MPa.

[0033] Furthermore, the cross-section of the hair implantation hole 111 is circular, and the diameter of the hair implantation hole is 2.0 mm to 3.0 mm. Preferably, the diameter of the hair implantation hole is 2.5 mm.

[0034] Furthermore, the number of bristles in the bristle bundle 12 is 60 to 230, and the bristle diameter is 0.10 mm to 0.18 mm. The more bristles in the bristle bundle 12 within the bristle implantation hole 111, the greater the compressive force between the bristles, and the less likely the bristles will fall off. However, if there are too many bristles in the bristle bundle 12 within the bristle implantation hole 111, the compressive force will be too great, which may cause the bristle implantation hole 111 to crack. Therefore, the number of bristles in the bristle bundle 12 is preferably 60 to 230, and the bristle diameter is preferably 0.10 mm to 0.18 mm.

[0035] Further, as a preferred embodiment, the cross-section of the hair implantation hole 111 is circular, the diameter of the hair implantation hole 111 is 2.3mm to 2.7mm, the number of bristles in the bristle bundle 12 is 94 to 177, and the bristle diameter is 0.10mm to 0.14mm.

[0036] Furthermore, a portion of the bristle implantation holes 111 are arranged in a circumferential array along the substrate 11 to form an outer peripheral bristle implantation hole group, while another portion of the bristle implantation holes 111 are located inside the outer peripheral bristle implantation hole group and arranged in a circumferential array along the substrate 11 to form an inner bristle implantation hole group. The spacing L2 between adjacent bristle implantation holes 111 in the inner bristle implantation hole group is greater than the spacing L1 between adjacent bristle implantation holes 111 in the outer peripheral bristle implantation hole group. Specifically, water stains are easily retained in the middle area of ​​a large-pore bristle toothbrush, leading to problems such as bacterial growth. This embodiment increases the spacing between the bristle bundles 12 in the middle area by increasing the spacing of the inner bristle implantation hole group, thereby reducing the aggregation between the bristle bundles 12, effectively reducing water stain residue, and reducing bacterial growth.

[0037] Furthermore, the bristle bundle 12 is made of a mixture of graphene and polyester materials. Graphene is a two-dimensional carbon nanomaterial with excellent bactericidal and bacteriostatic effects, which helps to improve the antibacterial effect of the bristle bundle 12 and reduce bacterial growth.
