Description

Technical field

[0001] The present invention relates to the field of sputum instruments, in particular to a sputum instrument hit.Background technique

[0002] When the thread is thick, the vibration dismissal can make the sputum easily coughed, and the sputum instrument is used to achieve a medical device for vibration. The sputum instrument includes a host and a slap, driven by the host. Put the slap in the rear back area corresponding to the human lungs, and the splitter vibration is to generate sniper to the region, so that the sputum is loose and easy to discharge.

[0003] The main structure of common sputum instruments is an eccentric shaft, and the eccentric shaft rotation causes vibration of the entire slap. The driver of the eccentric shaft is achieved by a soft shaft, that is, the sputum master is provided that the motor drives the soft shaft rotation, and the eccentric shaft is rotated. The disclosure of the patent disclosed in CN201020647872.4 and CN201610289066.6 is this structu...
