Description

Technical Field

[0001] This utility model relates to the field of interdental brush technology, and more particularly to a combined interdental brush. Background Technology

[0002] Interdental brushes are oral care tools specifically designed to clean the interproximal surfaces of teeth. Their core function is to compensate for the limitations of toothbrush bristles in reaching deep into the gaps between teeth, effectively removing food debris and plaque, and preventing interproximal caries and periodontal disease.

[0003] Chinese Patent Publication No. CN207679059U, published on August 3, 2018, discloses an interdental brush unit and its connecting strip, including a tab and a flat body. The front end of the tab is provided with a brush part, and the two sides of the body are respectively provided with connecting structures. The connecting structure is an arc-shaped groove, and the bottom of the arc-shaped groove is provided with a flange in the middle. The connecting structure is a protruding elastic strip, including several interdental brush units arranged side by side in the same direction. Adjacent interdental brush units are connected by an elastic body.

[0004] The bristles in existing interdental brushes are mostly perpendicular to the brush handle. The cleaning effect of interdental brushes can be further optimized. Therefore, there is an urgent need to propose a corresponding combination interdental brush to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to propose a combined interdental brush to solve the above-mentioned problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A modular interdental brush includes a handle and a brush bar. Multiple sets of rubber bristles are fixedly connected to the outer wall of the brush bar, and the multiple sets of rubber bristles form a 45-degree angle with the brush bar. A threaded seat is fixedly connected to the bottom of the brush bar, and the outer wall of the threaded seat is screwed together with the inner wall of the top of the threaded groove.

[0007] Preferably, a round seat is fixedly connected between the brush rod and the threaded seat.

[0008] Preferably, the outer wall of the round seat is fixedly connected with multiple sets of protruding teeth, which are arranged in a ring, and the outer wall of the handle is provided with a limiting part for axial positioning of the round seat.

[0009] Preferably, the limiting part includes an elastic strip fixedly connected to the outer wall of the handle, and the elastic strip engages between two adjacent sets of protruding teeth in a plurality of sets.

[0010] Preferably, the brush bar has a rounded head at the top.

[0011] Preferably, the outer wall of the handle is provided with a rough texture.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: 1. In this application, the threaded seat is screwed onto the handle through the threaded groove to fix the brush bar and the handle, thereby assembling the interdental brush as a whole. Multiple sets of rubber bristles are at a 45-degree angle to the brush bar, so that the rubber bristles can act as barbs to facilitate better cleaning of the gaps between teeth by the interdental brush, thereby improving the cleaning effect of the interdental brush. The screw-on connection method allows the brush bar of the interdental brush to be replaced independently without having to discard the handle together each time, thereby improving the energy efficiency of the interdental brush.

[0013] 2. In this application, the round seat and multiple sets of protruding teeth can form a gripping part to facilitate the screwing of the threaded seat and the handle. After the handle and the brush bar are fully screwed together, the elastic strip is released to lock between two sets of two of the multiple sets of protruding teeth, thereby providing axial constraint for the brush bar and further ensuring the stability of the connection between the brush bar and the handle.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-4 This utility model provides a technical solution: A combination interdental brush includes a handle 1 and a brush bar 2. Multiple sets of rubber bristles 3 are fixedly connected to the outer wall of the brush bar 2, and the multiple sets of rubber bristles 3 form a 45-degree angle with the brush bar 2. A threaded seat 9 is fixedly connected to the bottom of the brush bar 2, and the outer wall of the threaded seat 9 is screwed together through the inner wall of the top of the threaded groove 10. The threaded seat 9 is screwed onto the handle 1 via the threaded groove 10, thereby fixing the brush bar 2 to the handle 1 and assembling the interdental brush as a whole. Multiple sets of bristles 3 are at a 45-degree angle to the brush bar 2, allowing the bristles 3 to act as barbs, so that the interdental brush can better clean the gaps between teeth and improve the cleaning effect of the interdental brush. The screw-on connection method allows the interdental brush to replace the brush bar 2 independently without having to discard the handle 1 together each time, thereby improving the energy efficiency of the interdental brush.

[0018] Specifically, such as Figure 2 and Figure 4 As shown, a round seat 4 is fixedly connected between the brush rod 2 and the threaded seat 9. Multiple sets of protruding teeth 5 are fixedly connected to the outer wall of the round seat 4. The multiple sets of protruding teeth 5 are arranged in a ring. The outer wall of the handle 1 is provided with a limiting part for axial positioning of the round seat 4. The limiting part includes an elastic strip 8 fixedly connected to the outer wall of the handle 1. The elastic strip 8 is engaged between two adjacent sets of protruding teeth 5. The round seat 4 and the multiple sets of protruding teeth 5 can form a gripping part to facilitate the screwing of the threaded seat 9 and the handle 1. After the handle 1 and the brush rod 2 are fully screwed together, the elastic strip 8 is released to engage between two sets of protruding teeth 5, thereby providing axial constraint for the brush rod 2 and further ensuring the stability of the connection between the brush rod 2 and the handle 1.

[0019] Specifically, such as Figure 2 and Figure 3 As shown, the brush stick 2 has a round head 7 at the top to facilitate the brush stick 2 to fit into the gaps between teeth, and the outer wall of the handle 1 has a rough texture 6 to ensure the stability of the handle 1 when held.

[0020] Working principle: The threaded seat 9 is screwed onto the handle 1 via the threaded groove 10, thus fixing the brush bar 2 to the handle 1 and assembling the interdental brush as a whole. Multiple sets of rubber bristles 3 are at a 45-degree angle to the brush bar 2, allowing them to act as barbs to better clean the gaps between teeth and improve the cleaning effect. The screw-on connection allows the brush bar 2 to be replaced independently without having to discard the handle 1 each time, thus improving the energy efficiency of the interdental brush. The round seat 4, together with multiple sets of protruding teeth 5, forms a grip to facilitate the screwing of the threaded seat 9 onto the handle 1. After the handle 1 and brush bar 2 are fully screwed on, the elastic strip 8 is released and locked between two sets of protruding teeth 5, providing axial constraint for the brush bar 2 and further ensuring the stability of the connection between the brush bar 2 and the handle 1.

[0021] The above description of the embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
