180° variable guide vertical brush function toothbrush

Abstract

The invention discloses a toothbrush capable of guiding a vertically brushing function by changing within 180 degrees. The toothbrush comprises a brush handle, a brush head, a transmission gear group, a gear rack and a latch device, wherein the brush head is arranged at one end of the brush handle and is matched with the transmission gear group; the latch device is arranged on the brush handle; the gear rack is arranged in the brush handle; the transmission gear group is matched with the gear rack; the transmission gear group is arranged at one side of the gear rack; the latch device corresponds to the gear rack; first clamping teeth are formed in the inner side of the brush handle; and the first clamping teeth correspond to the latch device. The transmission gear group is driven to rotate by virtue of gears when the gear rack is pushed, and then the brush head is driven to rotate by virtue of the transmission gear group. Moving directions of the gear rack can be controlled by controlling pushing directions of the latch device, so that rotating directions of the brush head are changed, exactly the brush head can be controlled to swing leftwards by 90 degrees or controlled to swing rightwards by 90 degrees in accordance with demands in an actual using process; therefore, the brush head is kept to be perpendicular to the brush handle, so that the toothbrush can conveniently implement vertical brushing on teeth at the inner side along slits between the teeth and can conduct tooth brushing conveniently in a scientific model of vertically brushing, and subsequently, a purpose of cleaning the teeth is achieved.
