Description

[Technical Field]

[0001] The present invention relates to the field of teeth cleaning technology, and more particularly to a replaceable interdental brush having a core brush body and a method for manufacturing the same. [Background technology]

[0002] Toothbrushes are an indispensable oral hygiene tool in daily life, and there are many types of toothbrushes on the market, divided according to their functions into regular toothbrushes, spray toothbrushes, electric toothbrushes, room toothbrushes, single-head toothbrushes, and interdental brushes. Among them, interdental brushes are used to remove dirt and grime between teeth and are advantageous for cleaning between teeth. Commonly used interdental brushes consist of a handle and a brush body formed of bent and twisted thin metal wire, with brush bristles implanted between the metal wires. The brush body is generally cylindrical or conical, and the handle is generally made of synthetic resin and is often cylindrical in size to be held in the hand. The base of the metal wire in the brush body is usually fixed to the handle using other physical bonding methods, including insert molding, high-frequency and ultrasonic thermal bonding, etc., so that the brush body and the handle are integrated, and the metal brush body cannot be separated or replaced. Currently, steel wire is often used as the metal wire in the core of the brush body of interdental brushes on the market. However, the toughness of this metal wire generally means that the metal wire is easily damaged in a very short time, and after a few uses, it breaks at the base of the brush body (i.e., the connection point between the brush body and the grip). As a result, the entire interdental brush must be discarded and the grip cannot be reused. This means that such interdental brushes are used only a limited number of times and are not environmentally friendly.

[0003] Therefore, there is an urgent need to provide a replaceable interdental brush having a core brush body and a method for manufacturing the same. Summary of the Invention

[Figure 3] 1 is a structural schematic diagram of a brush body according to the present invention; [Figure 4] 1 is a structural schematic diagram of a fixing block according to the present invention; [Figure 5] FIG. 2 is a structural schematic diagram of the rotary lid according to the present invention; [Figure 6] 1 is a structural schematic diagram of a grip according to the present invention; DETAILED DESCRIPTION OF THE INVENTION

[0014] In order to achieve the above objects and effects, the technical means and structure adopted by the present invention will be described in detail with reference to the drawings in the preferred embodiments of the present invention.

[0015] As shown in Figures 1 to 6, the present invention comprises a grip 1, a rotating lid 2, a fixed block 3 and a brush body 4, wherein a male thread 13 is provided at the end of the grip 1, a female thread 12 is provided inside the rotating lid 2, the male thread 13 at the end of the grip 1 fits into the female thread inside the rotating lid 2, one end of the fixed block 3 abuts against the grip 1 and the other end protrudes from the rotating lid 2, the brush body 4 comprises a core 5 and brush bristles 6, the core 5 is formed by twisting amorphous alloy wires together, one end of the core 5 is clamped within the fixed block 3 and the brush bristles 6 are connected to the circumferential side of the other end.

[0016] In this embodiment, the grip 1 is "L" shaped and made of polyethylene (PE). Polyethylene is relatively soft, has a waxy feel, and is relatively lighter than comparable plastics. Making the grip from polyethylene improves the grip's softness, comfort, pressure resistance, and toughness. The grip is less likely to break when a consumer holds it, improving the durability of the interdental brush and improving the grip's anti-slip performance. When using the interdental brush, the interdental brush is less likely to slip out of the hand. When the grip is "L" shaped, there is a certain angle between the brush body and the grip, making it easier to remove dirt and plaque between the teeth.

[0017] In this embodiment, one end of the grip 1 is provided with a male thread 13, and the outer surface of the other end is formed with a textured pattern 14. The textured pattern on the outer surface of the Gripple increases the friction of the grip surface and further improves the grip's anti-slip performance, making it less likely for the grip to fall out of the consumer's hand and onto the ground when holding it to brush their teeth, preventing damage to the interdental brush. At the same time, the textured pattern arrangement improves the comfort of the consumer when holding the grip.

[0018] In this embodiment, the core 5 includes a free end 7 and a fixed end 8 that are connected to each other, the fixed end 8 being clamped within the fixed block 3, and the brush bristles 6 are wound around one side of the free end 7 of the core 5 and distributed radially. Because the free end of the brush body is provided with bristles distributed radially, the brush bristles can effectively clean between teeth in all directions.

[0019] One end of the interior of the rotating lid 2 is provided with a slope 11, and the other end is provided with an internal thread 12 that matches the external thread 13 of the grip 1. The fixing block 3 includes two clips arranged symmetrically, each with a through-hole 9 at its center for fixing the fixed end 8 of the core 5, and an inclined surface 10 at one end of its exterior that matches the slope 11 at one end of the interior of the rotating lid 2. In conventional interdental brushes, the brush body and grip are joined together using an injection molding process, and if the brush body breaks during use, the entire interdental brush must be discarded. The interdental brush of the present invention breaks through conventional interdental brush manufacturing methods by fastening the fixed end of the brush body to the tip of the grip via the fixing block and rotating lid. This design allows the brush body to be replaced if it breaks during use, and the other parts are recyclable.

[0020] In this embodiment, the amorphous alloy wire contains Zr 49 Cu 45 Al6 amorphous alloy wire, Zr 58 Cu 22 Fe8Al 12 Amorphous alloy wire, Zr 48 Cu 36 Ag8Al8 amorphous alloy wire, Zr 46.3 Cu 43.4 Al 8.3 Nb2 amorphous alloy wire, Zr 62.3 Cu 22.5 Fe 4.9 Al 6.8 Ag 3.5 Amorphous alloy wire, Ti 40 Zr 10 Cu 40-x Pd 10+x (x=0, 2, 4, 6, 8, 10) Amorphous alloy wire, Ti 40 Zr 10Cu 34 Pd 14 Sn2 amorphous alloy wire, Ti 44 Zr 10 Pd 10 Cu 6+x Co 23-x Ta7 (x= 0, 4, 8) amorphous alloy wire, Ti 47 Cu 38-x Zr 7.5 Fe 2.5 Sn2Si1Ag2Nb x (x=0, 1, 2) Amorphous alloy wire, Ti 47 Cu 38-x Zr 7.5 Fe 2.5 Sn2Si1Ag2Ta x (x=1, 2, 3, 4) Amorphous alloy wire and Pd 78 Si 16 The interdental brush includes any one of Cu6 amorphous alloy wires. Such amorphous alloy wires have high strength, good toughness, and do not contain elements harmful to the human body, making them less likely to break during use and more durable.

[0021] A method of manufacturing a replaceable interdental brush having a core brush body, comprising: The core 5 is made by twisting an amorphous alloy wire in a spiral shape around a central axis, and the brush body 4 is made by implanting the brush bristles 6 radially into the free ends 7 of the core 5 using a bristles implantation machine, so that the brush bristles 6 can effectively clean dirt between teeth in all directions S1; An injection molding material is injected into a mold to produce a grip 1 using an injection molding machine, and the grip 1 has a male thread 13 at one end and a textured pattern 14 on the outer surface of the other end (S2); Injecting an injection molding material into a mold to produce a rotating lid 2 using an injection molding machine, the rotating lid 2 having a slope 11 at one end inside and an internal thread 12 at the other end that matches the external thread 13 at one end of the grip 1 (S3); An injection molding material is injected into a mold, and a fixed block 3 is produced by an injection molding machine. The fixed block 3 includes two clips arranged symmetrically on the left and right, and has a through hole 9 at its center for fixing the fixed end 8 of the core 5, and an inclined surface 10 at one external end S4 that matches the gradient 11 at one internal end of the rotating lid 2.
