Fluid control device

Abstract

The invention discloses a fluid control device which comprises a piezoelectric actuator, a deformable base and a deformable base structure. The piezoelectric actuator is formed in the mode that a piezoelectric assembly is attached to the surface of a vibration plate. The piezoelectric assembly is deformed through applied voltage so as to drive the vibration plate to bend and deform. The vibrationplate is provided with a protrusion portion which is attached to the other surface of the piezoelectric assembly. The deformable base structure is composed of a flexible plate and a circulation platein a mutual stacked and connected mode, and can be subjected to synchronous deformation to form the synchronous deformation structure. The deformable base structure and the vibration plate of the piezoelectric actuator are correspondingly connected and positioned, and the deformable base structure is protruded and deformed in the direction close to the vibration plate, so that the specific depth is defined between the flexible plate and the vibration plate. The flexible plate is provided with a movable portion which is arranged relative to the protrusion portion.

Problems solved by technology

[0006] The main purpose of the present invention is to solve the problem that in the conventional fluid control device, due to the miniaturized design of the substrate and the piezoelectric actuator, it is difficult to accurately position and generate errors during assembly, making it difficult to maintain the gap after assembly. The distance is required, which leads to the low efficiency of fluid transportation and the problem of noise, which leads to inconvenience and discomfort in use.
