The motor 130 is connected with the housing 110, and the motor 130 is suitable for driving the pump body 100 to work through the transmission assembly 120; the rotation shaft of the motor 130 and the input shaft of the pump body 100 are arranged in parallel, or an included angle is formed between the rotation shaft of the motor 130 and the input shaft of the pump body 100. According to the oral care device provided by the embodiment of the utility model, the rotating shaft of the motor 130 is arranged in parallel with the input shaft of the pump body 100, or an included angle is formed between the rotating shaft of the motor 130 and the input shaft of the pump body 100, so that the total length of the oral care device is reduced, the length of the oral care equipment is greatly reduced, and the oral care equipment is convenient to carry.
According to one embodiment of the present invention, the rotation axis of the motor 130 forms an angle with the input axis of the pump body 100, where the angle is greater than 0 ° and less than 180 °.
According to an embodiment of the present invention, the rotation shaft of the motor 130 is disposed parallel to the input shaft of the pump body 100, or the rotation shaft of the motor 130 is perpendicular to the input shaft of the pump body 100. It should be noted that, when the rotating shaft of the motor 130 is parallel to the input shaft of the pump body 100, the input shaft of the pump body 100 and the rotating shaft of the motor 130 are located on the same side, so as to conveniently connect the input shaft of the pump body 100 and the rotating shaft of the motor 130 through the transmission assembly 120.

When the motor 130 rotates, the motor 130 drives the second taper tooth 122 to rotate through the first taper tooth 121, and since the hinge point of the piston rod 101 and the second taper tooth 122 is not on the axis of the second taper tooth 122, the second taper tooth 122 drives the piston of the piston pump to reciprocate through the piston rod 101, so that the piston pump sucks in liquid and outputs liquid. The piston pump has an advantage in that the pressure of the liquid discharged from the nozzle 180 can be increased as compared with other types of the pump body 100, and the greater the pressure of the water, the better the cleaning effect, thereby effectively removing fine food residues and harmful bacteria adhered to the teeth or gums.

When the second cone teeth 122 rotate around the first rotation axis, the eccentric bushing 123 drives the piston rod 101 to reciprocate.
It should be noted here that, in the case where the cylinder size of the piston pump is fixed, the moving distance of the reciprocating motion of the piston rod 101 determines the amount of liquid output by the piston pump at a time, and the moving distance of the reciprocating motion of the piston rod 101 is determined by the distance between the axis of the eccentric sleeve 123 and the axis of the second taper tooth 122. The larger the distance between the axis of the eccentric sleeve 123 and the axis of the second taper tooth 122 is, the larger the liquid amount output by the piston pump each time is, so in the specific implementation process, the distance between the axis of the eccentric sleeve 123 and the axis of the second taper tooth 122 can be determined according to the liquid amount output by the piston pump each time.
