Grinding wheel and toothbrush grinding apparatus having the same

摘要

The present invention relates to a grinding wheel and a toothbrush grinding apparatus having the grinding wheel. Particularly, the present invention discloses a toothbrush grinding wheel comprising a cylindrical grinding barrel, and the main point of the technical solution is that, the toothbrush grinding wheel comprises a plurality of rows of grinding grains disposed on the outer periphery surface of the cylindrical grinding barrel. The present invention further discloses a toothbrush grinding apparatus comprising a stationary base, a swiveling bracket disposed on the stationary base, and a toothbrush grinding wheel disposed on the swiveling bracket. The toothbrush grinding wheel comprises a cylindrical grinding barrel, wherein a retainer for clamping a toothbrush is disposed on one side of the cylindrical grinding barrel, and there are a plurality of rows of grinding grains disposed on the outer periphery surface of the cylindrical grinding barrel. The present invention overcomes the disadvantages in prior arts, such as poor bristle grinding effects of the grinding wheel, easy occurrence of burrs, easy wearing out and high cost of the soft belt, so as to provide a low cost grinding wheel that is resistant to wear and does not need frequent replacement. Bristle grinding effect is greatly improved, the occurrence of burrs is reduced and the roundness of the bristle heads is increased.
