Miniatrized hydraulic electronic pump and its manufacture

Abstract

The present invention relates to a hydraulic electron pump in new ultramicro-type and its process to overcome problems of low performance, easy blocking, easy decompressing and low efficiency of flow and operation existed in original technology, which consists of piezoelectric ceramic invertion plate fixed in pump cavity formed by pump body and pump cover, outer setting one way valve of pump liquid inlet in plug in individual piece and one way valve formed by internal assembling valve gate of valve body and spring. Its manufacturing process covers film layer on the back of inverting plate and then to fix it in pump body cavity, to cover rubber layer on the front face of inverting plate, to weld to pump body together with pump cover in one body and then to plug in one way valve.

Description

(1) Technical field [0001] The invention relates to an ultra-micro pump, and specifically refers to an ultra-micro hydraulic electronic pump and a manufacturing method thereof. (2) Background technology [0002] In the background art, most of the hydraulic pumps generally sold on the market are mechanical, large in size, not easy to miniaturize, and difficult to install. The patent applicant of the present invention began to study ultra-micro electronic pumps as early as the early 1990s. It began to be used in handicrafts, such as water spraying water crafts, Fengshui model humidifiers, etc.; in 2001, the inventor applied for a patent "multi-purpose ultra-micro electronic pump", although this pump overcomes and solves the difficulty of reducing the size of hydraulic pumps , It is not easy to install, the flow is small, the head is low, and it is not easy to break and break. However, due to the miniaturization of the pump, the internal cavity channel of the pump is narrow, and the...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to develop a new type of ultra-miniature hydraulic electronic pump and its manufacturing process on the basis of the inventor's many years of research and use of the ultra-miniature electronic pump and the original patent application, to overcome and solve the problem of the ultra-miniature electronic pump in the original technology. It is easy to block and release pressure under long-term work, resulting in poor working stability and poor positioning of the ball valve. On the basis of ensuring the miniaturization of the volume, the flow rate and working efficiency of the pump are improved, and the quality and comprehensive performance of the product are improved. The consistency prolongs the service life of the product, expands the scope of use, and is more suitable for large-scale industrial production
