The application provides a MEMS actuating cooling chip based on a double one-way valve open structure, and belongs to the technical field of micro-electro-mechanical systems. The cooling chip comprises a vibration assembly, a driving assembly and a sealing film. The vibration assembly comprises a vibration layer, the vibration layer comprises a central vibration piece and connecting pieces, and the connecting pieces are arranged on the outer circumferential side of the central vibration piece. The driving assembly is configured to drive the vibration assembly to vibrate, the driving assembly comprises a first substrate and a second substrate, the first substrate is configured in a ring shape, the connecting pieces are connected to the first side of the first substrate, the second substrate is arranged on the second side of the first substrate to enclose the first substrate and the second substrate to form a cooling cavity, the first substrate is provided with a first opening, and the second substrate is provided with a second opening. The sealing film can seal the gap between two adjacent connecting pieces. When the driving assembly drives the vibration layer to vibrate, the cooling cavity can suck in fluid through the first opening and spray out fluid through the second opening. The application has high heat dissipation efficiency.

The utility model relates to the technical field of water-based resin processing, in particular to a mixing device for synthesizing water-based resin, which comprises a supporting seat, a mixing barrel is fixedly mounted on the supporting seat, a rotary stirring mechanism is arranged on the mixing barrel, and the rotary stirring mechanism is movably mounted on a turntable at the top of the mixing barrel. Two first motors are symmetrically and fixedly mounted on the rotating disc, and two stirring rods connected with the output ends of the first motors are symmetrically and movably mounted at the bottom of the rotating disc. Through the arrangement of the rotary stirring mechanism, the flowability of raw material stirring can be improved, and on the basis of stirring of the two stirring rods, the two stirring rods rotate while stirring through rotation transmission of the second motor and the turntable, so that the flowability and the stirring amplitude of the raw materials are improved, and the stirring speed of the raw materials is increased. The raw materials are mixed more sufficiently, and the raw material mixing and stirring effect is improved.
