Abstract
Description
[Technical Field]
[0002] This utility model relates to the field of oral hygiene products, and in particular to an antibacterial toothbrush. [Background Technology]
[0004] In recent years, people have paid increasing attention to the importance of oral health. Toothbrushes, as an essential tool for cleaning teeth in daily life, clean teeth and the mouth. Their main function is to remove food debris, bacteria, and plaque from the tooth surface. Through brushing, the bristles of the toothbrush can effectively clean all surfaces of the teeth. However, during brushing, the bristles are easily contaminated by bacteria in the mouth, especially when there is residual moisture on the bristles, which further promotes bacterial growth. After brushing, the toothbrush is exposed to the environment during storage, coming into close contact with bacteria in the environment, such as bacteria in the air and sink. Therefore, to prevent toothbrush contamination and avoid further impact on oral health, toothbrushes with antibacterial functions are gaining popularity.
[0005] Currently, antibacterial toothbrushes on the market include graphene composite antibacterial toothbrushes. Although graphene composite antibacterial toothbrushes can achieve antibacterial effects on the brush head during use, the bristles with added graphene components are less mechanically strong and resilient than traditional nylon bristles, making them prone to shedding. This results in the inability to maintain the antibacterial effect on the brush head for a long time, thus failing to effectively clean oral health and hygiene. [Utility Model Content]
[0007] To address the technical problem that graphene bristles are prone to shedding, which prevents effective sterilization and antibacterial treatment of the brush head and effective cleaning of oral health, this invention proposes an antibacterial toothbrush.
[0008] This utility model is achieved by the following technical solution:
[0009] An antibacterial toothbrush includes a brush head and a handle. The brush head is provided with a bristle assembly for cleaning oral hygiene and a bristle implantation hole for implanting the bristle assembly. The bristle assembly includes a plurality of first bristles for antibacterial purposes. An anti-shedding component is provided in the bristle implantation hole for pressing the folded part of the bristles to prevent the bristles from falling out.
[0010] In the antibacterial toothbrush described above, the anti-shedding component is a steel sheet, and the anti-shedding component has multiple grooves at the bristle fold for embedding the first bristles into the bristle implantation hole.
[0011] As described above, in an antibacterial toothbrush, the grooves are triangular in shape and there are four grooves.
[0012] In the antibacterial toothbrush described above, the depth D of the groove is 0.03-0.07 mm, and the width W1 of the groove is 0.1-0.17 mm.
[0013] In the antibacterial toothbrush described above, the length L of the anti-loosening component is 2.1-2.6 mm, the width W2 of the anti-loosening component is 1.3-1.7 mm, and the thickness T of the anti-loosening component is 0.15-0.4 mm.
[0014] As described above, in an antibacterial toothbrush, the first bristles have a dual-core structure, with the outer core of the first bristles made of a mixture of graphene and polyester materials, and the inner core of the first bristles made of polyester materials.
[0015] As described above, in an antibacterial toothbrush, the bristle assembly further includes a plurality of second bristles made of nylon material.
[0016] In the antibacterial toothbrush described above, the bristle implantation hole in the middle region A1 of the brush head is used to implant the first bristles, and the bristle implantation holes in the two end regions B1 of the brush head are used to implant the second bristles.
[0017] As described above, in an antibacterial toothbrush, the handle is provided with a raised component for anti-slip purposes, the raised component being composed of a plurality of small protrusions.
[0018] As described above, in an antibacterial toothbrush, the first bristles are tapered filaments, the length of the first bristles is 28-32 mm, and the diameter of the first bristle filaments is 0.12-0.2 mm.
[0019] The second brush bristles are spiral bristles, the length of the second brush bristles is 28-32mm, and the diameter of the second brush bristles is 0.12-0.2mm.
[0020] Compared with the prior art, the antibacterial toothbrush proposed in this utility model has the following beneficial effects:
[0021] 1. The first bristles of the antibacterial toothbrush proposed in this utility model can be inserted into the bristle implantation hole in a folded manner through the anti-shedding component in the implantation hole. This not only increases the contact area between the bristles and the implantation hole, but also makes the distribution of the bristles in the implantation hole more uniform, improving the overall stability and firmness, and preventing the first bristles from falling out during use. This allows the antibacterial effect on the brush head to be maintained for a long time. At the same time, the anti-shedding component ensures the stability of the first bristles, enabling users to more effectively remove dirt and bacteria from the mouth and improve cleaning ability.
[0022] 2. The anti-shedding component proposed in this utility model has multiple grooves at the folded part of the brush bristles for embedding the first brush bristles into the bristle holes, which can significantly improve the tufting force and monofilament force of the first brush bristles when embedding them, and prevent the first brush bristles from loosening or falling off during use.

Detailed Implementation Methods
[0036] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0037] Specific embodiments, combined with Figures 1 to 8 As shown, the technical solution of this utility model is further explained. An antibacterial toothbrush includes a brush head 10 and a brush handle 20. The brush head 10 is provided with a bristle assembly 11 for cleaning oral hygiene and a bristle implantation hole 12 for implanting the bristle assembly 11. The bristle assembly 11 includes a plurality of first bristles 111 and a plurality of second bristles 112 for antibacterial purposes. The bristle implantation hole 12 for implanting the first bristles 111 is provided with an anti-shedding component 30 for pressing the folded part of the bristles to prevent the bristles from falling off. The first bristles 111 of this antibacterial toothbrush can be inserted into the bristle implantation hole 12 in a folded manner through the anti-shedding component 30 in the implantation hole 12. This not only increases the contact area between the bristles and the implantation hole, but also makes the distribution of the bristles in the implantation hole more uniform, improving the overall stability and firmness, and preventing the first bristles 111 from falling out during use. This allows the toothbrush to maintain its antibacterial effect on the brush head 20 for a long time. At the same time, the anti-shedding component 30 ensures the stability of the first bristles 111, enabling users to more effectively remove dirt and bacteria from the mouth and improving cleaning ability.
[0038] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the anti-shedding component 30 is a steel sheet, and the anti-shedding component 30 is provided with a plurality of grooves 31 facing the fold of the bristles for embedding the first bristles 111 into the bristle implantation hole 12, so as to improve the bristle bundle tension and single filament tension of the first bristles 111 in the bristle implantation hole 12.
[0039] The anti-hair loss component 30 is disposed in the middle of the hair implantation hole 12 so that the first bristles 111 can be inserted into the hair implantation hole 12 in a folded manner.
[0040] Furthermore, the number of grooves 31 is three or more. In this embodiment, the number of grooves 31 is four. The grooves 31 can be trapezoidal, square, or triangular. In this embodiment, the grooves 31 are triangular.
[0041] In this embodiment, the first bristles are inserted into the bristle planting hole in a folded manner through the anti-shedding component. This not only increases the contact area between the bristles and the bristle planting hole, but also makes the distribution of the bristles in the bristle planting hole more uniform, thereby improving the overall stability and firmness. The groove design can significantly improve the bristle bundle tension and monofilament tension when the first bristles are embedded, preventing the first bristles from loosening or falling off during use.
[0042] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the depth D of the groove 31 is 0.03-0.07 mm, and the width W1 of the groove 31 is 0.1-0.17 mm;
[0043] In this embodiment, the depth D of the groove 31 is 0.05±0.01mm, and the width W1 of the groove 31 is 0.13±0.03mm. In specific implementation, the depth D and width W1 of the groove 31 can be adjusted according to actual needs.
[0044] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the length L of the anti-detachment component 30 is 2.1-2.6 mm, the width W2 of the anti-detachment component 30 is 1.3-1.7 mm, and the thickness T of the anti-detachment component 30 is 0.15-0.4 mm.
[0045] In this embodiment, the length L of the anti-detachment component 30 is 2.3±0.1mm, the width W2 of the anti-detachment component 30 is 1.5±0.1mm, and the thickness T of the anti-detachment component 30 is 0.25±0.03mm. In specific implementation, the length L, width W2, and thickness T of the anti-detachment component 30 can be adjusted according to actual needs.
[0046] Furthermore, as a preferred embodiment of this solution and not a limitation, the number of the bristle holes 12 is equal to the sum of the number of the first bristles 111 and the number of the second bristles 112.
[0047] The bristle implantation hole 12 in the middle region A1 of the brush head 20 is used to implant the first bristle 111, and the bristle implantation hole 12 in the two end regions B1 of the brush head 20 is used to implant the second bristle 112.
[0048] In this embodiment, since water stains and dirt are easily left in the middle part of the toothbrush, which is the part where bacteria are most likely to grow, the first bristles are implanted in the middle part of the toothbrush head, thereby significantly reducing the number of bacteria and achieving a better antibacterial effect. In addition, the middle part of the toothbrush is the part that comes into most contact with the teeth and gums when cleaning oral hygiene. This arrangement can achieve the best cleaning effect.
[0049] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the first bristle 111 has a dual-core structure, the outer core of the first bristle 111 is made of a mixture of graphene and polyester materials, the inner core of the first bristle 111 is made of polyester materials, and the second bristle 112 is made of nylon materials.
[0050] In this embodiment, graphene is a two-dimensional carbon nanomaterial with excellent bactericidal and bacteriostatic effects. Using it to make the first bristles can ensure that the growth and reproduction of bacteria can be effectively inhibited when cleaning oral hygiene. At the same time, graphene is composed of carbon elements and is non-toxic, so it can achieve long-term antibacterial and antimicrobial effects.
[0051] In addition, the first bristle has a double-core structure, which gives it excellent antibacterial effect, as well as a certain degree of mechanical strength and wear resistance. This makes the first bristle less prone to falling out while still having antibacterial ability, thus extending its service life and giving the toothbrush long-term antibacterial ability.
[0052] Furthermore, as a preferred embodiment of this solution and not a limitation, the bristles of the first bristle 111 are tapered filaments (the tip diameter of the toothbrush bristles is ≤0.01mm), the bristle length of the first bristle 111 is 28-32mm, and the filament diameter of the first bristle 111 is 0.12-0.2mm.
[0053] In this embodiment, the bristle length of the first bristle 111 is 30mm, and the bristle diameter of the first bristle 111 is 0.125±0.01mm. In specific implementation, the bristle length and bristle diameter of the first bristle 111 can be adjusted according to actual needs.
[0054] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the bristles of the second bristle 112 are spiral bristles, the bristle length of the second bristle 112 is 28-32mm, and the bristle diameter of the second bristle 112 is 0.12-0.2mm.
[0055] In this embodiment, the bristle length of the second bristle 112 is 30mm, and the bristle diameter of the second bristle 112 is 0.178±0.01mm. In specific implementation, the bristle length and bristle diameter of the second bristle 112 can be adjusted according to actual needs.
[0056] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the hair implantation hole 12 is circular in shape, the depth of the hair implantation hole 12 is 3.3-3.8 mm, and the diameter of the hair implantation hole 12 is 1.6-2 mm.
[0057] In this embodiment, the depth of the hair implantation hole 12 is 3.5 mm and the diameter of the hair implantation hole 12 is 1.8 mm. In the specific implementation process, the depth and diameter of the hair implantation hole 12 can be adjusted according to actual needs.
[0058] Taking a single hair implantation hole 12 as an example, if the bristle diameter is 0.125mm, the number of bristles that can be implanted in a single hair implantation hole 12 is 41±10.
[0059] Furthermore, as a preferred embodiment of this solution and not a limitation, the brush handle 20 is provided with a protrusion component 21 for anti-slip purposes, the protrusion component 21 being composed of a plurality of small protrusions, the plurality of small protrusions being hexagonal protrusions.
[0060] In this embodiment, the raised component is composed of multiple hexagonal protrusions, which can provide more contact points, greatly increasing the friction between the fingers and the brush handle, thereby significantly improving the anti-slip ability. At the same time, the hexagonal protrusions can fit the shape of the fingers more closely, reducing the discomfort of holding the brush handle and improving the user experience.
[0061] The working principle of this embodiment is as follows:
[0062] This utility model proposes an antibacterial toothbrush that reduces the shedding of the first bristles 111 during use through the anti-shedding component 30 and improves the antibacterial ability and cleaning effect of the toothbrush by adjusting the arrangement of the first bristles 111 on the brush head 10. The specific principle is as follows:
[0063] The first bristles 111 are implanted in the bristle implantation hole 12 in the middle area A1 of the brush head 10, and the second bristles 112 are implanted in the bristle implantation hole 12 in the two end areas B1 of the brush head 10. This arrangement can reduce the growth of bacteria in the middle part of the toothbrush and achieve the best cleaning effect. The bristle implantation hole 12 with the first bristles 111 is provided with an anti-detachment component 30. The anti-detachment component 30 has four triangular grooves 31 facing the fold of the bristles, so that the first bristles can be inserted into the bristle implantation hole 12 in a folded manner. The triangular grooves can significantly improve the bristle bundle tension and monofilament tension of the first bristles 111 when they are embedded, preventing the first bristles 111 from loosening or falling out during use and avoiding the phenomenon of easy bristle loss.
