Ejector

By adjusting the flow channel space and pipe volume of the pumps in the distributor, a constant proportion of liquid is discharged when multiple pumps operate simultaneously, solving the problem of uneven liquid volume in traditional distributors, simplifying the manufacturing process and improving operational stability.

AI Technical Summary

Technical Problem

In traditional distributors, when multiple pumps operate simultaneously, it is difficult to maintain a constant ratio of liquid discharge from different outlets, resulting in uneven liquid volume during the initial discharge and requiring multiple pressurization operations to fill the flow channel space, which increases complexity.

Method used

Design a distributor in which the volume change ratio of the flow channel space of multiple pumps is consistent when pressure is applied. By adjusting the internal structure of the pumps, such as the pipe volume and flow channel space, ensure that the volume change of each flow channel is consistent when pressure is applied, so as to achieve a constant ratio of liquid discharge when multiple pumps operate simultaneously.

Benefits of technology

This technology enables the liquid to be discharged from each outlet in a constant proportion when multiple pumps are operating simultaneously, simplifying the manufacturing process, avoiding liquid oxidation and leakage, and improving ease of operation and stability.

Abstract

To make amounts of content fluids different at a certain ratio even when a plurality of pumps are placed in simultaneous operation to discharge the content fluids from all of a plurality of discharge holes for the first time.SOLUTION: A discharger 1 comprises pumps 13, 14 and a push-down head 15, which has a plurality of discharge holes 16, 17 formed to communicate with insides of a plurality of stems 11, 12 individually. In the discharger, a plurality of circulation spaces A1, A2 for content fluid is provided causing insides of container bodies W1, W2 containing content fluids to communicate with the plurality of discharge holes individually, and also includes the stems. The circulation spaces are different, in decrement in circulation space capacity when the push-down head 15 and stems are moved down to descent end positions, from each other, but equal, in ratio of the circulation space capacity and the decrement in circulation space capacity when the push-down head and stems are moved down to descent end positions, to each other.SELECTED DRAWING: Figure 1
