AI Technical Summary

Technical Problem

Existing liquid ejection mechanisms, such as inkjet methods, generate mist that can cause contamination within the device due to aerosols floating and adhering inside, leading to potential chemical and biological contamination post-ejection, and existing techniques do not adequately address this issue.

Method used

A liquid dispensing device and method that incorporates a discharge section with a shielding section to cover the opening portion, a stage for moving the discharge section relative to storage compartments, and a moving mechanism to position the discharge section accurately, along with an air intake and exhaust system to manage aerosols, ensuring the internal space is shielded from the external environment.

Benefits of technology

The solution effectively suppresses contamination by minimizing the mixing of aerosols and mist within the device, maintaining a sterile environment during liquid dispensing and reducing the need for frequent user cleaning.

Abstract

To provide a liquid discharge device, a liquid discharge method, a dispensing device, and a compound introduction device that can prevent the occurrence of contamination in liquid after discharge.SOLUTION: A liquid discharge device has discharge means having a discharge part and a discharge energy generating element that discharges liquid from the discharge part to an internal space of a storage part capable of storing discharged liquid by using a discharge principle of an ink jet system. When discharging liquid, the discharge means covers an opening portion of the storage part to block the internal space of the storage part from an external space.SELECTED DRAWING: Figure 1
