Description

Technical Field

[0001] The invention relates to medical instruments, in particular to an interdental brush with self-flushing function. Background Art

[0002] After people have a meal, there is always food left between the teeth. For this reason, people have invented tools to clean the food residue between the teeth. Common tools include toothpicks, dental floss, toothbrushes, interdental brushes, water floss, etc.

[0003] Toothpicks, dental floss, toothbrushes and interdental brushes on the market can clean some visible food residues between teeth.

[0004] After using the above tools to clean, users can further clean the loose residues by rinsing their mouths, but due to the insufficient impact force of water, some small residues with strong adhesion cannot be cleaned away. Moreover, toothpicks and dental floss can easily hurt the user's gums and oral cavity walls if used improperly. Water flossing can avoid the above problems because it only has the impact force of water and will not scratch or pierce the oral cavity due to improper use. However, in order to clean the residues with particularly strong adhesion between teeth, high water pressure must be used, but this high water pressure will cause redness and swelling of the gums after impacting the gums.

[0005] An existing interdental brush monomer is as follows Figure 1 As shown, it includes a pick portion 12 and a flat body 11, the front end of the pick portion 12 is provided with a brush portion 121, and the two side edges (the sides in the thickness direction when placed horizontally) of the body 11 are respectively provided with connecting structures. The connecting structure is an arc groove 112. Anti-slip structures 111 are respectively provided on the flat surfaces on both sides of the body 11. The anti-slip structure 111 is a plurality of evenly distributed grooves arranged on the body 11; further optimization is performed by filling the grooves with latex to improve the comfort of holding. The arc groove 112 is a through structure from top to bottom, and the arc groove 112 between adjacent interdental brush units 1 and the mold (upper mold and lower mold) form a cavity for accommodating the elastomer. After using this interdental brush to clean the teeth, it is necessary to further clean the loose residues by rinsing the mouth. Summary of the invention
