Description

Technical Field

[0001] The utility model relates to the technical field of electric toothbrushes, and particularly relates to a small-diameter drum-shaped brush. Background Art

[0002] The drum-shaped brush is mainly used for rotary electric toothbrushes. At present, the spiral type for rotary electric toothbrushes mostly uses a twisted wire method. There are problems of discomfort in use for the oral cavity regarding the density and hardness of the bristles. If the density is poor, it is easy to cause insufficient cleanliness, and if the hardness is high, it will cause damage to the gums. Therefore, this application proposes a small-diameter drum-shaped brush that can effectively improve the comfort in use. Summary of the Utility Model

[0003] The purpose of the utility model is to address the deficiencies in the above technologies and propose a small-diameter drum-shaped brush, aiming to solve the existing problems.

[0004] The utility model provides a small-diameter drum-shaped brush, which includes a brush body and a brush rod for fixing the brush body. The brush body is spirally wound and adhered to one end of the brush rod to form a drum structure; bristles are evenly arranged on the brush body. The wire diameter of the bristles is 0.02 - 0.12 mm. The length of the bristles is 1.8 - 10 mm. The central axis diameter of the brush rod at the position of the bristles is 0.3 - 10 mm. The top of the bristles is a wave structure.

[0005] Preferably, the brush body includes multiple spiral segments, and the multiple spiral segments are connected to the brush rod by adhesion. The radian of the spiral segment is 180° - 270°.

[0006] Preferably, the brush body is a strip structure, and the brush body is adhered to the brush rod by being bent into a spiral structure. The brush body is made of a flexible material.

[0007] Compared with the prior art, it has the following beneficial effects:

[0008] In this application, the brush body with bristles adhered or formed by thermoplastic molding is adhesively fixed to the brush rod by spiral winding. Adopting this solution can effectively ensure the bristle density of the brush, reduce the problem of discomfort in use for the oral cavity, and effectively improve its cleanliness and avoid gum damage. Brief Description of the Drawings

[0019] To more easily understand the structure of the present utility model and the functional features and advantages that can be achieved, the preferred embodiments of the present utility model will be described in detail below in conjunction with the drawings as follows:

[0020] Embodiment:

[0021] As Figures 1 to 3 shown, the present utility model provides a small-diameter drum-type brush, including a brush body 1 and a brush rod 2 for fixing the brush body 1. The brush body 1 is spirally wound and adhered or heat-melted to one end of the brush rod 2 to form a drum structure; bristles 3 are evenly arranged on the brush body 1, and the bristles 3 are located on the outer side surface of the spiral-structured brush body 1, so that when the electric toothbrush drives the brush rod 2 to rotate, the bristles 3 can be driven to rotate synchronously to clean the teeth.

[0022] See Figure 5 , the wire diameter of the bristles 3 of this application is 0.02 - 0.12 mm.

[0023] See Figure 5 , the length of the bristles 3 of this application is 1.8 - 10 mm.

[0024] See Figure 5 , the central axis diameter of the brush rod 2 at the position of the bristles 3 is 0.3 - 10 mm.

[0025] See Figure 8 , the top of the bristles 3 is a wavy structure to facilitate tooth cleaning.

[0026] As another embodiment of the present application, as Figure 6 and Figure 7 shown, the brush body 1 of the present application includes multiple spiral segments, and the multiple spiral segments are connected to the brush rod 2 by pasting or heat melting. In this embodiment, the brush body 1 with a multiple spiral segment structure is combined to form a multi-layer spiral structure. Further, the radian of the spiral segment of the present application is from 180 degrees to 270 degrees, preferably 180 degrees.

[0027] As another embodiment of the present application, as Figure 4 and Figure 5 shown, the brush body 1 of the present application is a strip structure, and the brush body 1 is bent into a spiral structure and glued to the brush rod 2. The brush body 1 is made of a flexible material so that it can be spirally bent and wound around the brush rod 2.

[0028] The above are only the preferred embodiments of the present utility model, and do not impose any form of limitation on the present utility model. Any person skilled in the art can, without departing from the scope of the technical solution of the present utility model, make many possible changes and modifications to the technical solution of the present utility model by using the above technical content, or modify it into an equivalent embodiment with equivalent changes.
