Safe interdental brush

Abstract

The utility model provides a safe interdental brush which comprises a handle and a brush head fixedly arranged at one end of the handle, the brush head comprises a main body and a plurality of bristles evenly distributed on the outer surface of the main body, the main body comprises at least one stainless steel wire and at least one non-metal silk thread, and the stainless steel wire and the non-metal silk thread are made of stainless steel. The stainless steel wire and the non-metal wire are wound in a spiral mode. According to the utility model, the main body is formed by spirally winding the non-metal wire and the stainless steel wire, so that when the stainless steel wire in the main body is fractured due to fatigue, the non-metal wire cannot be fractured due to fatigue. Due to the fact that the stainless steel wire and the non-metal wire are wound in the spiral mode, the stainless steel wire broken into two sections can be connected through winding of the non-metal wire, namely, the brush head and the handle cannot be completely separated, and the situation that a stainless steel trunk falls off to cause harm to consumers in the using process is avoided.

Description

Technical Field

[0001] The utility model relates to the technical field of oral cleaning, in particular to a safe interdental brush. Background Art

[0002] An interdental brush, also known as a dental floss brush or an interproximal brush, is shaped like a small washing bottle and is a single-bundle brush. There are various sizes and models available for selection. The smaller interdental brushes are generally equipped with a handle for easy holding and use. The interdental brush is a small brush specifically designed to clean the interdental spaces (which cannot be reached by ordinary toothbrushes).

[0003] In the prior art, the structure of an interdental brush includes a handle and a brush head. The main body of the brush head is generally made of stainless steel. According to the standard, the main body of the brush head should not break during use. However, in actual use, as Figure 1 shown, it is a common phenomenon that the main body of the brush head breaks or falls off. When the main body breaks or falls off, a part of the main body will remain in the user's mouth, and the user may accidentally swallow the fallen stainless steel main body into the stomach, which will cause harm to the consumer's body. Summary of the Utility Model

[0004] The main purpose of the utility model is to provide a safe interdental brush to solve the problem that in the prior art, during the use of the interdental brush, its main body breaks or falls off, which will cause harm to the consumer's body.

[0005] To solve the above problems, the utility model adopts the following technical solution: A safe interdental brush includes a handle and a brush head fixedly provided at one end of the handle. The brush head includes a main body and a plurality of bristles evenly distributed on the outer surface of the main body. The main body includes at least one stainless steel wire and at least one non-metallic material wire, and the stainless steel wire and the non-metallic material wire are spirally wound.

[0006] Further, there are two stainless steel wires.

[0007] Further, the non-metallic material wire is made of any one of nylon, polyester, polyethylene, bamboo charcoal fiber, and Teflon.

[0008] Further, the handle includes a holding part and a connecting part detachably connected to one end of the holding part, and one end of the brush head is fixedly inserted into the connecting part.

[0009] The beneficial effects of the utility model are:

[0010] By setting the main trunk to be spirally wound with non-metallic wire and stainless steel wire, when the stainless steel wire in the main trunk breaks due to fatigue, the non-metallic wire will not break due to fatigue. Since the stainless steel wire and the non-metallic wire are spirally wound, the non-metallic wire will continue to connect the broken stainless steel wire to each other, that is, the brush head and the handle will not be completely separated, thereby avoiding the stainless steel main trunk falling off during use to cause harm to consumers.

[0019] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0020] See also Figures 2 to 4As shown, a safe interdental brush comprises a handle 1 and a brush head 2. In this embodiment, the handle 1 comprises a gripping portion 11 and a connecting portion 12, and the connecting portion 12 is detachably connected to one end of the gripping portion 11. The brush head 2 is used to clean the interdental spaces of the user, and one end of the brush head 2 is fixedly inserted in the connecting portion 12. By setting the connecting portion 12 and the gripping portion 11 as a detachable connection, it is convenient for the user to replace the brush head 2 and the connecting portion 12.

[0021] The brush head 2 includes a trunk 21 and a plurality of bristles 22 fixed on the trunk 21. The plurality of bristles 22 are evenly arranged along the axial direction and the circumferential direction of the trunk 21. Figure 3 , Figure 4 As shown, the trunk 21 includes at least one stainless steel wire 211 and at least one non-metallic wire 212, and the stainless steel wire 211 and the non-metallic wire 212 are spirally wound. Preferably, in this embodiment, there are two stainless steel wires 211 to increase the strength of the trunk 21, so as to avoid the stainless steel wire 211 of the trunk 21 being too soft, resulting in the trunk 21 being unable to extend into the user's tooth gap, or being bent too much after extending into the user's tooth gap, and being easily broken.

[0022] In this embodiment, the material of the non-metallic material thread 212 is any one of nylon (polyamide fiber), polyester (polyester fiber), ethylene (polyethylene fiber), bamboo charcoal fiber, and Teflon (polytetrafluoroethylene), that is, the non-metallic material thread 212 is a fiber thread that is not easy to break, similar to the fiber thread used to make dental floss, so that the non-metallic material thread 212 will not fatigue and break during use.

[0023] See also Figure 2 Combined with Figure 4 As shown, when the utility model is implemented, the user inserts the brush head 2 of the interdental brush into the interdental space to clean the interdental space. When the stainless steel wire 211 in the main body 21 breaks due to fatigue, the non-metallic wire 212 will not break due to fatigue. Since the stainless steel wire 211 and the non-metallic wire 212 are spirally wound, the winding of the non-metallic wire 212 will continue to connect the broken stainless steel wire 211 to each other, that is, the brush head 2 and the handle 1 will not be completely separated, thereby preventing the stainless steel main body 21 from falling off during use and causing harm to consumers.

[0024] The above description is only a preferred embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
