Common cleaning devices for injection inner packaging materials mainly include bottle washing devices, drying devices and connecting and conveying devices. The bottle washing device generally includes a cleaning pool, an ultrasonic device, a conveyor belt and a bottle grabbing and turning device. The conveyor belt sends the ampoule to be cleaned into the cleaning pool. The ultrasonic device ultrasonically cleans the ampoule entering the cleaning pool. Then, the bottle grabbing and turning device grabs the ultrasonically cleaned ampoule and turns it over so that the bottle mouth faces downward to drain. Then, the ampoule is placed with the bottle mouth facing downward on the connecting and conveying device for connecting and conveying.
