Abstract: A multifunctional cup handle includes a cup body. An upper portion of an outer side of a wall of the cup body is provided with a cup protrusion. A fixed shaft is provided on the cup protrusion. An upper end of a bending handle is provided with a handle shaft hole. The handle is sleeved on the fixed shaft. A locking device is provided on the fixed shaft. When a lower end of the bending handle is rotated to a highest position, the locking device locks the handle shaft hole, such that the lower end located directly above the cup body forms a lifting yoke of the cup body. When the lower end of the bending handle is rotated to a lowest position, the locking device locks the handle shaft hole, such that the bending handle at a side of the cup body forms a grip of the cup body.

Abstract: A thermos cup vacuumizing device and method are provided. The thermos cup vacuumizing device includes a pre-vacuumizing chamber, a heating chamber, a welding chamber, and a cooling chamber. A continuous conveying device is provided at a bottom of each of the chambers. The thermos cup vacuumizing device further includes a controllable and movable laser welding device and multiple transparent windows. A laser beam of the laser welding device passes through the transparent windows to melt a welding ball at provided at a hole in the center of the bottom of the thermos cup. A vertically movable inlet valve is provided at an inlet of the pre-vacuumizing chamber, and a vertically movable outlet valve is provided at an outlet of the cooling chamber. The present disclosure realizes the continuous vacuumizing operation on the thermos cups, improves the product qualification rate and processing efficiency, and realizes automatic mass production.
