Vibration back-buckling sputum excretion device

The utility model discloses a vibrating back-buckling sputum excretion device, and particularly relates to the related technical field of sputum excretion devices, according to the vibrating back-buckling sputum excretion device, a storage battery is respectively connected with a speed adjusting knob and a driving motor through wires, when the vibrating back-buckling sputum excretion device is used, the rotating speed of the driving motor can be achieved by adjusting the speed adjusting knob, and the rotating speed of the driving motor is adjusted; therefore, the vibration frequency of the vibration mechanism is adjusted, and the sputum excretion requirements of babies of different month ages can be met. When the driving motor rotates, the cam presses the vibration connecting piece downwards, at the moment, the vibration connecting piece overcomes the elastic force of the spring and then moves downwards, when the cam rotates by 180 degrees, the vibration connecting piece is located at the uppermost position,
