Abstract: A U-shaped toothbrush for manually squeezing toothpaste, comprising a U-shaped dental sleeve, a dental sleeve holder disposed in the U-shaped dental sleeve, a handle container for accommodating toothpaste, and a hollow insertion shaft, a toothpaste hole of the dental sleeve holder, and one end of the insertion shaft is connected to the dental sleeve holder, and the other end is connected to the handle container, and the handle container is provided with a toothpaste pushing mechanism for pushing the toothpaste to move into the insertion shaft. The toothpaste pushing mechanism pushes the toothpaste in the handle container, so that the toothpaste is pushed from the handle container to the U-shaped dental sleeve, then the toothbrush could be used to brush the teeth, which is convenient; the toothpaste in the handle container could be completely used up, and the toothbrush could be re-used by repeatedly adding toothpaste.

Abstract: A bracket-type tooth cleaner comprises a dental sleeve with bristles, a vibrating frame embedded in the dental sleeve, a motor and a housing for accommodating the motor; a spindle of the motor is fixedly connected to the vibrating frame, so that the vibrating frame drives the dental sleeve to vibrate. The advantage of the bracket-type tooth cleaner is that: the motor drives the vibrating frame to vibrate to cause the vibration of the dental sleeve, and the bristles on the surface of the dental sleeve clean the teeth. Since the shape of the dental sleeve is the same as the shape of the teeth, the tooth cleaner could clean teeth without dead angles; the motor drives the bristles on the surface of the dental sleeve to vibrate at a high speed, so the gaps between teeth could be effectively cleaned. The structure of the tooth cleaner is simple.
