The working principle of the utility model is as follows:
before using, need to carry out the winding work: firstly, the switch component needs to be shifted to a closed state, namely, a button is pressed, the brake shifting roller drives the brake bowl to slide along the sliding shaft to the direction of the brake rotor and enables the brake rotor to be wedged into the brake hole, and the speed-increasing gear transmission mechanism is braked and stopped. Then, when the knob assembly is rotated (for example, clockwise), the rib on the locking cup is abutted against one end of the two sliding pins and moves along the radial direction, and the other end of the two sliding pins is abutted against two side surfaces of the shaft sleeve, so that the spring shaft is driven to rotate together, and the spring mechanism is enabled to store energy. After the winding work is finished, the locking cup resets, the sliding pin releases the conflict on the shaft sleeve under the action of the compression spring, and the linkage relation between the knob assembly and the winding shaft is released. During the winding work, although the input gear of the speed-up gear transmission mechanism cannot rotate due to braking, the winding shaft can still rotate relative to the input gear under the action of the unidirectional rotation linkage assembly.
When the toothbrush is used, the switch component is switched to an open state, namely the button is pressed, the braking poking roller drives the braking bowl to reversely slide along the sliding shaft to remove the wedging relation between the braking rotor and the braking hole, the clockwork spring mechanism releases kinetic energy to enable the clockwork spring shaft to rotate anticlockwise, the input gear is driven by the retaining spring piece of the one-way knob linkage component to rotate, the rotating speed of more than two thousand rotations is transmitted to the swinging component through each transmission gear piece and each output gear piece, the swinging component is driven to swing at a high speed, and then the toothbrush head is driven to realize the tooth brushing action.
