Description

An interdental brush with self-flushing

technical field

The invention relates to medical instruments, in particular to an interdental brush with self-flushing.

Background technique

After eating, there will always be food left in the gaps between the teeth. For this reason, people have invented tools to clean the food residues between the teeth. The common ones are toothpicks, dental floss, toothbrushes, interdental brushes, water flossers, etc. .

Toothpicks, floss, toothbrushes, and interdental brushes are available on the market to remove food residue that is partially visible between the teeth.

After cleaning with the above tools, the user can further clean up the loose residue by gargling, but due to the insufficient impact force of the water, there are still some small residues with strong adhesion that cannot be removed. Moreover, improper use of toothpicks and floss can easily damage the user's gums and the inner wall of the oral cavity. Water flossing can avoid the above problems, because only the impact of water will not scratch or poke the mouth due to improper use, but in order to clean the residue with particularly strong adhesion between teeth, high water pressure must be used, but this When high water pressure hits the gums, it can cause red and swollen gums.

An existing interdental brush unit is shown in FIG. 1 , which includes a tab portion 12 and a flat body 11. The front end of the tab portion 12 is provided with a brush portion 121. , the thickness direction side) are respectively provided with connection structures.
