LIQUID DROPLET DISCHARGING APPARATUS - A simplified explanation of the abstract

This abstract first appeared for US patent application 18507201 titled 'LIQUID DROPLET DISCHARGING APPARATUS

Simplified Explanation:

This patent application describes a liquid droplet discharging apparatus that uses a piezoelectric element to apply pressure to liquid inside a pressure chamber, allowing for the precise discharge of liquid droplets from a nozzle. The natural frequency of the liquid inside the channel, the recording resolution of the image to be recorded by the droplets, and the diameter of the nozzle are all important factors in the design of this apparatus.

• The apparatus includes a channel member with a channel containing a nozzle and a pressure chamber.
• A piezoelectric element is fixed to the channel member to apply pressure to the liquid in the pressure chamber for droplet discharge.
• The natural frequency of the liquid in the channel is between 120 kHz to 160 kHz.
• The recording resolution of the image to be recorded by the droplets is not less than 1200 dpi.
• The diameter of the nozzle and the natural frequency of the liquid satisfy a specific equation: D≥0.0343×Fr+6.6979.

Potential Applications:

This technology can be used in inkjet printers, 3D printing, medical devices, and microfluidic systems.

Problems Solved:

This technology solves the problem of precise liquid droplet discharging for high-resolution imaging and printing applications.

Benefits:

The benefits of this technology include high precision in liquid droplet discharging, improved image quality, and increased resolution in printing applications.

Commercial Applications:

This technology can be commercially applied in the manufacturing of high-resolution printers, medical devices, and microfluidic systems.

Questions about liquid droplet discharging apparatus: 1. How does the natural frequency of the liquid affect the performance of the apparatus? 2. What are the potential commercial applications of this technology in the medical field?

Original Abstract Submitted

A liquid droplet discharging apparatus includes: a channel member having a channel including a nozzle and a pressure chamber communicating with the nozzle; and a piezoelectric element fixed to the channel member and configured to apply pressure to liquid inside the pressure chamber to discharge liquid droplets of the liquid from the nozzle. A natural frequency Fr of the liquid inside the channel is in a range of 120 kHz to 160 kHz, a recording resolution which is a resolution of an image to be recorded by the liquid droplets is not less than 1200 dpi; and a diameter D [μm] of the nozzle and the natural frequency Fr [KHz] satisfy: D≥0.0343×Fr+6.6979.
