Electric nasal aspirator with anti-blocking and cleaning functions

An electric nasal aspirator with anti-blocking and cleaning functions, comprising a housing assembly, which is a hollow chamber, wherein the housing assembly is provided with an exhaust hole and an air suction column penetrating through the housing assembly;

• a circuit board, fixedly arranged in the housing assembly;
• a collection cup assembly, detachably arranged on the housing assembly, wherein the collection cup assembly comprises an outer cover, a collection cup, and a suction nozzle;
• the outer cover is detachably hermetically connected to the housing assembly;
• the collection cup comprises a connecting column and a collection chamber;
• the connecting column is hollowly tubular and detachably arranged on the air suction column;
• an upper end of the connecting column is provided with at least one air suction hole penetrating through the upper end;
• the air suction column is communicated to a hollow chamber encircled by the outer cover and the housing assembly;
• the collection chamber is fixedly arranged on the connecting column and closely abuts against an inner wall of the outer cover;
• at least one air suction slot body penetrating through a side edge of the collection chamber is arranged on the side edge, and the outer cover is communicated to the suction nozzle through the at least one air suction slot body;
• the suction nozzle is detachably connected to the outer cover and extends into the collection cup;
• the nasal mucus is directly collected and stored in the collection cup through the suction nozzle;
• an air pump assembly, configured to provide a negative pressure suction force for the collection cup assembly, wherein the air pump assembly is hermetically communicated to the air suction column and the exhaust hole and is electrically connected to the circuit board;
• a button assembly, fixedly arranged on the circuit board and penetrating through the housing assembly, wherein the button assembly controls on/off and function settings of the nasal aspirator;
• and
• a battery assembly, fixedly arranged in the housing assembly and configured to provide electric energy for the circuit board, the air pump assembly, and the button assembly.
