AI Technical Summary

Technical Problem

The existing peristaltic pump piping uses a segmented structure, which leads to unstable connections, easy loosening and leakage under high pressure, and difficult assembly. In addition, it requires the use of multiple specifications of piping, which increases the complexity of inventory management and usage costs.

Method used

Design an integrally molded booster pump tube, including an upper thin tube, an upper pagoda head, a thick tube, a lower pagoda head, and a lower thin tube. It is integrally molded from silicone material, forming a through flow channel inside. The pagoda head is smoothly connected to the thick tube, providing reliable tooling fit and avoiding stress concentration.

Benefits of technology

It ensures the reliability and sealing of pipeline connections, avoids leakage problems, simplifies assembly operations, improves filling accuracy and production efficiency, and reduces quality risks.

Abstract

This utility model provides an integrally molded booster pump pipe, comprising an upper thin pipe, an upper pagoda head, a thick pipe, a lower pagoda head, and a lower thin pipe connected in sequence. The upper thin pipe, upper pagoda head, thick pipe, lower pagoda head, and lower thin pipe form an integrally molded structure with a through-flow channel inside. Both the upper and lower pagoda heads are frustum-shaped. The small ends of the two pagoda heads are positioned opposite each other and connected to both ends of the thick pipe, while the large ends of the two pagoda heads are connected to the upper and lower thin pipes, respectively. The diameter of the thick pipe is larger than the diameters of the upper and lower thin pipes. This integrally molded booster pump pipe completely eliminates the connection gaps of traditional segmented pipelines through its integrated structural design, achieving a completely closed-loop delivery of the liquid medicine. The frustum-shaped pagoda head provides reliable tooling fit and a smooth pipe diameter transition, effectively solving the problems of loose pipeline connections, easy loosening and leakage under high pressure, and difficult assembly in existing technologies, thus improving the safety, reliability, and ease of use of the liquid medicine delivery.
