Safe interdental brush

Abstract

Provide a safe interdental brush that can prevent a situation where the wire of a stainless steel wire falls off during use and poses a danger to the user. 【Solution means】It includes a handle 1 and a brush head 2 fixed to one end of the handle. The brush head includes a wire 21 and a plurality of brushes 22 evenly distributed on the outer surface of the wire. The wire has at least one stainless steel wire 211 and at least one non-metallic thread 212. The stainless steel wire and the non-metallic thread are wound in a spiral shape. In the present invention, the wire is formed by winding a non-metallic thread and a stainless steel wire in a spiral shape. Even if the stainless steel wire of the wire is fatigued and fractured, the non-metallic thread is not fatigued and fractured. Since the stainless steel wire and the non-metallic thread are wound in a spiral shape, the wound non-metallic thread continuously connects the stainless steel wires to each other even if it breaks into two, so that the brush head does not detach from the handle.

Description

Technical Field

[0001] The present invention relates to the field of oral cleaning technology, and more specifically, to a safe interdental brush. That is, even if the stainless steel wire of the wire of the interdental brush is fatigued and broken, the non-metallic thread is not fatigued and broken. Since the stainless steel wire and the non-metallic thread are wound spirally, the wound non-metallic thread continuously connects the stainless steel wires that have broken into two, so that the brush head does not completely detach from the handle, and the stainless steel wire does not fall off during use to endanger consumers.

Background Art

[0002] The interdental brush is also called an inter-dental brush. Those with a shape similar to a small bottle brush are called end-tuft brushes, and there are various sizes, forms, and model numbers to choose from. The small interdental brush is usually inserted into a handle for easy gripping and use. The interdental brush is a small toothbrush designed to clean the interdental spaces (which cannot be reached by an ordinary toothbrush).

Summary of the Invention

Problems to be Solved by the Invention

[0003] However, in the above-mentioned conventional technology, the structure of the interdental brush includes a handle and a brush head. Generally, the wire of the brush head is made of stainless steel. Based on the standard specifications, the wire of the brush head does not break during use. However, during actual use, as shown in FIG. 1, the wire of the brush head often breaks or falls off. When the wire breaks or falls off, a part of the wire may remain in the user's mouth, and an accident may occur where the user swallows the fallen stainless steel wire, posing a danger to the user's body.

[0004] Therefore, the present inventor believes that the above-mentioned drawbacks can be improved, and as a result of intensive research, the present invention has been proposed to effectively improve the above-mentioned problems through reasonable design.

[0005] The present invention has been made by the intensive research of the present inventor in view of the above problems, and its purpose is to provide a safe interdental brush.

Means for Solving the Problems

[0006] In order to solve the above problems, a safe interdental brush according to an aspect of the present invention includes a handle and a brush head fixed to one end of the handle. The brush head includes a wire and a plurality of brushes evenly distributed on the outer surface of the wire. The wire includes at least one stainless steel wire and at least one non-metallic thread, and the stainless steel wire and the non-metallic thread are wound spirally.

[0007] In a preferred example of the present invention, the number of the stainless steel wires is two.

[0008] In a preferred example of the present invention, the material of the non-metallic thread is any one of nylon, polyester fiber, ethylene, bamboo charcoal fiber, Teflon (registered trademark), or a similar material.

[0009] In a preferred example of the present invention, the handle includes a grip portion and a connection portion removably connected to one end of the grip portion, and one end of the brush head is inserted and fixed in the connection portion.

Effects of the Invention

[0010] According to the present invention, the following effects are obtained. The wire is formed by winding a non-metallic thread and a stainless steel wire spirally. Even if the stainless steel wire of the wire is fatigued and broken, the non-metallic thread is not fatigued and broken. Since the stainless steel wire and the non-metallic thread are wound spirally, the wound non-metallic thread continuously connects the two broken stainless steel wires to each other so that the brush head does not completely detach from the handle. It is ensured that the stainless steel wire does not fall off during use and pose a danger to consumers.

[0011] From the descriptions in the following specification and drawings, at least the following matters will become clear.

Modes for Carrying Out the Invention

[0013] Hereinafter, embodiments of the present invention will be described in detail. However, the present invention is not limited thereto, and various modifications are possible within the described range, and embodiments obtained by appropriately combining the technical means disclosed in different embodiments are also included in the technical scope of the present invention.

[0014] First, an example of a specific embodiment of the safe interdental brush of the present invention will be described with reference to FIGS. 2 to 4.

[0015] The safe interdental brush according to the present invention includes a handle 1 and a brush head 2. In this embodiment, the handle 1 includes a grip portion 11 and a connection portion 12, and the connection portion 12 is removably connected to one end of the grip portion 11. The brush head 2 is used to clean between the user's teeth, and one end of the brush head 2 is inserted and fixed within the connection portion 12. By installing the connection portion 12 and the grip portion 11 to be removably connected, it is made easier for the user to replace the brush head 2 and the connection portion 12.

[0016] The brush head 2 includes a wire 21 and a plurality of brushes 22 fixed to the wire 21, and the plurality of brushes 22 are uniformly arranged along the axial direction and the circumferential direction of the wire 21. As shown in FIGS. 3 and 4, the wire 21 includes at least one stainless steel wire 211 and at least one non-metallic thread 212, and the stainless steel wire 211 and the non-metallic thread 212 are wound spirally. Preferably, in this embodiment, there are two stainless steel wires 211, and in order to prevent the stainless steel wires 211 of the wire 21 from being too soft to enter between the user's teeth, or from bending too much and being easily broken after entering between the user's teeth, the strength of the wire 21 is increased.

[0017] In this embodiment, the material of the non-metallic thread 212 is any one of nylon (polyamide fiber), polyester fiber (polyester fiber), ethylene (polyethylene fiber), bamboo charcoal fiber, Teflon (registered trademark) (polytetrafluoroethylene), or a similar material. That is, the non-metallic thread 212 is difficult to break and is similar to the fiber thread used to manufacture dental floss, and the non-metallic thread 212 will not fatigue and break during use.

[0018] Referring to FIGS. 2 and 4 again, when the present invention is specifically implemented, the user inserts the brush head 2 of the interdental brush into the tooth gap to clean the tooth gap. Even if the stainless steel wire 211 of the wire 21 breaks due to fatigue, the non-metallic thread 212 does not break due to fatigue. Since the stainless steel wire 211 and the non-metallic thread 212 are wound spirally, the wound non-metallic thread 212 connects the stainless steel wires 211 that have broken into two, preventing the brush head 2 from completely detaching from the handle 1. In this way, it is possible to prevent a situation where the stainless steel wire 21 falls off during use and poses a danger to the consumer.

[0019] The above embodiments are for facilitating the understanding of the present invention and are not for limiting and interpreting the present invention. It goes without saying that the present invention can be changed and improved without departing from its gist, and equivalents of the present invention are included therein.
