Toothbrush capable of automatically squeezing toothpaste

Abstract

The invention discloses a toothbrush capable of automatically squeezing toothpaste. The toothbrush comprises a brush head and a brush handle. The brush head is connected with the head of the brush handle. The inside of the brush handle is equipped with a toothpaste bottle and a toothpaste squeezing device. The brush head is equipped with a toothpaste outlet pipe. The brush head communicates with the toothpaste bottle through the toothpaste outlet pipe. One end of the toothpaste squeezing device can be in abut joint with the toothpaste bottle. The other end of the toothpaste squeezing device isconnected with an output shaft of a motor. The motor can drive the toothpaste squeezing device to move along the axial direction of the brush handle back and forth. The motor is electrically connected with a circuit board. By arranging the motor in the toothbrush, the motor can drive the toothpaste squeezing device to move along the axial direction of the brush handle. Therefore, toothpaste in the toothpaste bottle can be squeezed out. Finally, the toothpaste flows to the toothbrush through the toothpaste outlet pipe. Because the circuit board is arranged in the brush handle, rotating speed and continuous working time of the motor can be controlled by the circuit board. Therefore, a fixed amount of toothpaste can be squeezed when the toothbrush is used each time.

Description
