Glue hanging-free piezoelectric dispensing valve

The utility model relates to the field of dispensing devices, in particular to a glue-hanging-free piezoelectric dispensing valve, which comprises a valve seat, a nozzle and an airflow shielding cover, a flow channel is arranged in the valve seat, the nozzle is connected to an outlet end of the valve seat and communicated with the flow channel, the airflow shielding cover is connected to the periphery of the nozzle, and the airflow shielding cover is communicated with the nozzle. The airflow shielding cover extends out of the nozzle in the axis direction of the nozzle. According to the glue-hanging-free piezoelectric dispensing valve, the airflow shielding cover plays a windproof role while not influencing the dispensing action of the nozzle, and the glue is prevented from being influenced by surrounding airflow when the glue is sprayed out through the nozzle, so that glue hanging is avoided, the dispensing quality is improved, meanwhile, redundant glue at the nozzle can be directly cleaned after the dispensi
