Abstract
The invention discloses a piezoelectric pump and a valve block thereof. The piezoelectric pump comprises a lower casing, a sealing ring, a valve shelf, the valve block , a transduction film and an upper casing. One important method is realized in such a way that a cylindrical surface of the valve shelf and a cylindrical surface of the lower casing are tightly matched and positioned; the valve block of the piezoelectric pump is a sheet made of a soft rubber material; the valve block is arranged and positioned at two ends of the valve in a riveting manner; after mounting, a cylinder body of the valve shelf generates the pretension stress for the valve block; and the surface of the valve has no mutation and sharpness. According to the methods, the consumption of idle work can be effectively reduced, the work stability of the piezoelectric pump is improved and the efficiency of the piezoelectric pump in the design aspects of the valve shelf and valve block part is greatly increased.
Description
Technical field
The present invention relates to micropump, particularly, relating to a kind of is the piezoelectric pump of energy conversion device with the piezoelectric ceramic.
Background technique
Piezoelectric pump is a kind of new pump, because its energy-conserving and environment-protective, many advantages such as volume is little, in light weight, noise is low, no electromagnetic interference, and is had an optimistic view of its application prospect by many technical staff authors and businessman; This pump because it is an emerging industrial field, has many technical foundation Work Research not do and cuts, and the lifting of technical order still has the place that much haves much room for improvement with large-scale production application.
Summary of the invention
The present invention is from the installing and locating of piezoelectric pump vavle shelf, valve block class part, the performance index that the development and Design aspect promotes piezoelectric pump.
Technological scheme of the present invention is following: a kind of piezoelectric pump, comprise lower casing, seal ring, vavle shelf, valve block, transducing sheet and upper casing, and one of them important method is that the cylndrical surface of vavle shelf and the cylndrical surface of lower casing are the drive fit location.The valve block of this pump is the thin slice of processing with flexible glue material (like silica gel, soft PE); The mode of usefulness riveted joint (like rivet hot) is installing and locating at the two ends of valve; The cylinder that the back vavle shelf is installed produces pre-tensile stress to valve block; The surface of valve do not have sudden change, do not have sharply, preferably streamlined, fluid flows into end and done flow deflecting cone, and the hole of riveted joint usefulness and post are with center symmetry or equal mode for cloth layouts, and these methods can reduce the consumption of idle work effectively; Improve its working stability and reliability, it has greatly promoted the efficient of pump at the design aspect of vavle shelf, valve block class part.

Embodiment
Below in conjunction with accompanying drawing and specific embodiment, the present invention will be described in more detail.
Fig. 1 is the structural drawing of piezoelectric pump among the present invention, and is the bivalve pump, and this pump comprises lower casing (1), seal ring (2), seal ring (3), vavle shelf (4), valve block (5), transducing sheet (6) and upper casing parts such as (7).Upper casing (7) is connected with screw with lower casing (1) or method such as ultrasonic welding is organically combined these parts and formed a complete piezoelectric pump.Valve block among the embodiment (5) is made with silica gel, and hardness is about Shao Shi 60 degree, and flow deflecting cone (103) has been done in the fluid inflow side; Mounting hole (104) and column (105) arrange with centrosymmetric mode, is riveted together the part among Fig. 2 and Fig. 4 with the mode of rivet hot.External member after the riveted joint is assembled into one with (101) face of vavle shelf (4) and (102) face of lower casing (1) with friction tight mode, if water outlet is not adorned valve block (5), the bivalve pump has just become the single valve pump.For (101) face of vavle shelf among the embodiment (4) and (102) the face fit form and the valve structure of lower casing (1), our example was done many test comparison, had confirmed that also our method effect is pretty good.
