Control device for working of sputum excretion machine and sputum excretion machine

The invention discloses a sputum excretion machine work control device and a sputum excretion machine, and relates to the field of detection.The sputum excretion machine work control method comprises the steps that when a user wears a vibration vest of the sputum excretion machine in advance, the sputum excretion machine is controlled to work at a preset vibration frequency; collecting a set of pressure values of the vibration vest in a preset period at a preset collection frequency; in the actual use process of a user, the pressure value of the vibration vest in the complete vibration period is obtained; judging that the pressure value of the vibration vest in the complete vibration period is in a set of the pressure values of the vibration vest in a preset period; if yes, the sputum excretion machine is controlled to continue to work according to the preset vibration frequency; if not, the sputum excretion machine is controlled to stop working. If the user coughs in the process of using the sputum excretion
