No-clean integrally-formed negative pressure cup

Abstract

The utility model relates to the technical field of negative pressure cups, in particular to a no-clean integrally-formed negative pressure cup which comprises a cup body and a cup cover installed at the top end of the cup body in a sealed mode. The cup body comprises a cavity capable of storing electrolyte and a suction nozzle rod communicated with the cavity, and the suction nozzle rod and the bottom end of the cup body are integrally formed; the cup cover comprises a cover body and a connector integrally formed with the cover body, one end of the connector is communicated with the cavity, and the other end of the connector is connected with a negative pressure pipe used for providing negative air pressure. The outer side wall of the connector is provided with a protruding part which enables the connector to be in direct insertion interference fit connection with the negative pressure pipe. The suction nozzle rod and the cup body are integrally formed, so that the inner wall of the suction nozzle rod and the inner wall of the cavity are in stain connection, smooth and free of any gap, electrolyte fluidity is effectively promoted, crystal residues are avoided, cleaning can be avoided for a long time, manpower and material resources for cleaning are saved, and water resources are saved.
