Abstract:
A built-in toothpaste type toothbrush structure includes toothbrush casing, toothpaste inner tube, knob switch, toothpaste storage handle and pushing structure. The toothbrush casing includes a toothbrush head, an accommodating space, and an outlet and a socketing portion. The toothbrush casing is sheathed on the toothpaste inner tube and has a toothpaste channel inside, and the toothpaste storage handle is connected integrally with the toothpaste inner tube for storing toothpaste, and the pushing structure is installed in the toothpaste storage handle to push the toothpaste to the toothbrush head. Therefore, the knob switch can control the communication between the toothpaste inner tube and the toothbrush casing to avoid contaminating the toothpaste stored in the toothpaste inner tube, so that home and office users or students can carry and use the toothbrush for dental cleaning and oral hygiene conveniently.
