Abstract

The invention discloses a lever amplification type piezoelectric pump. The lever amplification type piezoelectric pump comprises an upper pump body, a lower pump body, a lever frame, a flexible sheet, a clamping ring, a piezoelectric brake, a spring, umbrella-shaped valves, nuts and a bearing, wherein the piezoelectric brake is arranged in a piezoelectric brake fixing groove of the upper pump body, and one end of the piezoelectric brake drags the lever frame; the lever frame is used for driving the spring and the flexible sheet to move; the umbrella-shaped valves are arranged at an inlet and an outlet of the lower pump body respectively, and the umbrella-shaped valves are fixed through sealing rings; and through matching of fixing bolts and the nuts, the upper pump body and the lower pump body are assembled, and assembling of the piezoelectric pump is completed. The lever amplification type piezoelectric pump has the advantages of high output flow, low cost and the like.

Description

technical field [0001] The invention relates to a lever amplified piezoelectric pump, which belongs to the field of fluid machinery. Background technique [0002] Traditional piezoelectric pumps use piezoelectric sheets or piezoelectric stacks as drivers, and use changes in the internal volume of the pump body to generate a pressure difference between the inside and outside of the pump body to form a one-way flow of liquid. However, the deformation of the driver is low, resulting in The small volume change of the piezoelectric pump limits the output flow of the piezoelectric pump, making it difficult for the piezoelectric pump to be widely used in fields such as drip irrigation in agricultural test fields. Contents of the invention [0003] Aiming at the problems existing in the current valveless piezoelectric pump, the present invention proposes a piezoelectric pump with high output flow. [0004] The technical solution adopted in the present invention is: a lever-amplif...
