This utility model discloses a portable electric suction device, relating to the field of suction device technology. It includes a handle, a negative pressure pump, a trachea, and a suction tube. The negative pressure pump is installed inside the handle, which has a switch for controlling it. The output end of the negative pressure pump is connected to the trachea. It also includes an intermediate cylinder with a partition at its center, dividing the cylinder into two chambers: an auxiliary chamber and a collection chamber. This utility model effectively prevents sputum backflow by separating the auxiliary and collection chambers with a filter. Gas enters the auxiliary chamber through a channel and is discharged to the outside, while sputum falls directly into the collection cylinder. A piston block and spring are installed inside the auxiliary chamber. When the suction tube becomes blocked, the suction force of the negative pressure pump moves the piston block upward, creating a buffer space to prevent continuous high pressure from damaging the mucosa. Furthermore, medical personnel can instantly release the negative pressure by pulling down the piston rod, quickly clearing the blocked viscous sputum and improving the sputum removal effect.
