Description

Technical Field

[0001] This utility model relates to the field of toiletries, and in particular to a composite interdental brush. Background Technology

[0002] Dental floss can reach the gaps between teeth that toothbrushes cannot reach, effectively removing food debris and plaque. Regular flossing can prevent cavities and gum disease.

[0003] like Figure 1 The dental floss 20 shown has a main working part made of a thin thread 21 made of nylon or polyester fiber. When using it, the thin thread 21 is moved to the top of the tooth and slid down into the gap between the teeth. The thin thread 21 is driven to slide and clean food debris and plaque from the tooth surface. In order to ensure that the dental floss 20 can enter the gap between the teeth smoothly, the diameter of the thin thread 21 is small, which also results in a small contact area between the thin thread 21 and the teeth and low cleaning efficiency. Figure 2 The interdental brush 30 consists of a wire 31 and a brush 32 fixed to the surface of the wire 31. The brush 32 can efficiently remove stains from between teeth. However, due to the presence of the brush 32, the working part of the interdental brush 30 cannot enter the gaps between teeth as smoothly as dental floss 20. When using it, the wire 31 needs to be inserted into a larger gap at the root of the tooth. This process will press on the gums. Therefore, if you are not careful when using the interdental brush 30, the wire 31 may pierce the gums and cause bleeding.

[0004] Given the aforementioned problems with existing dental floss and interdental brushes, it is necessary to design an interdental cleaning tool that offers both effective cleaning and ease of use. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a composite interdental brush that can quickly clean food debris and plaque from between teeth while avoiding damage to the gums during use.

[0006] The objective of this utility model is achieved through the following technical solution:

[0007] A composite interdental brush, comprising: a plastic handle, a handle sleeve, and a cleaning line;

[0008] The plastic rod includes an integrally formed grip and an arc-shaped support. The arc-shaped support has two mating ends. The cleaning line is located on the arc-shaped support. The two mating ends are used to keep the cleaning line taut. The outer wall of the grip has a sliding groove.

[0009] The inner wall of the sleeve is provided with a protrusion, the sleeve is used to wrap the grip part, and the protrusion is embedded in the groove;

[0010] The cleaning line includes a transition section and two main cleaning sections. The main cleaning sections are located on the cleaning line at the position where they contact the docking end. The thickness of the transition section is less than the thickness of the main cleaning sections, and the main cleaning sections are provided with bristles.

[0011] In one embodiment, the end of the grip is provided with a cleaning hook.

[0012] In one embodiment, the sleeve has a single-sided opening structure, and the grip portion is slidably disposed within the sleeve.

[0013] In one embodiment, the plastic rod is further provided with an adjustment part located on the grip part and exposed outside the rod sleeve.

[0014] In one embodiment, the surface of the adjustment part is provided with a first anti-slip stripe.

[0015] In one embodiment, the transition section and the main cleaning section are integrally formed.

[0016] In one embodiment, the length of the transition section is equal to the length of the main cleaning section.

[0017] In one embodiment, the outer wall of the sleeve is provided with a second anti-slip stripe.

[0018] In one embodiment, the bow-shaped support has cleaning teeth on the side facing away from the cleaning line.

[0019] The above-mentioned composite interdental brush has the following beneficial effects:

[0020] 1. The center of the cleaning line is a smooth transition section, which makes it easy to insert the cleaning line into the gap between teeth. The two ends of the transition section are the main cleaning sections with bristles, which allows the cleaning line to be easily inserted into the gap between teeth and to use the bristles to efficiently clean the dirt in the gap between teeth.

[0021] 2. The sleeve and the plastic rod are slidably connected. Applying force can push the plastic rod out of the sleeve, effectively extending the plastic rod. This makes it easier for users to move the bow-shaped support to the teeth that need cleaning. The sleeve and the plastic rod are also detachable. After cleaning, the plastic rod can be removed, and the sleeve can be reused, making it environmentally friendly and convenient. Attached Figure Description
