Liquid Supplying Device Ink Flow Passage Arrangement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing liquid supplying device for printers experiences inefficiencies in gas-liquid substitution due to the positioning of the liquid and gas flow passages, which can interrupt the flow of gas and hinder the efficient transfer of ink from the cartridge to the sub tank, affecting the operability and continuity of the printing process.
Innovation Solution
The device includes a tank and a cartridge with specifically arranged liquid and gas passages, where the liquid passage extends upward from the first opening and the gas passage extends upward from the second opening, both connected to a joint that allows for efficient communication and substitution, ensuring smooth ink transfer and reducing the size of the sub tank while maintaining ink storage capacity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the liquid flow passage and gas flow passage are positioned at an equal distance from the air introduction opening, then the structure is simplified, but the gas flow is interrupted by the liquid flow passage and gas-liquid substitution cannot be carried out efficiently
Solution Approach 1:
The gas flow passage is repositioned to a different spatial location relative to the liquid flow passage, specifically positioning its opening higher than the liquid flow passage opening. This dimensional rearrangement in the vertical direction allows gas to flow smoothly without being blocked by the liquid flow passage, thereby improving gas-liquid substitution efficiency while maintaining structural simplicity.
2Ease of manufacture
If the gas flow passage opening is positioned lower to simplify the structure, then manufacturing is easier, but gas cannot flow smoothly toward the gas flow passage from the air introduction opening
Solution Approach 1:
Instead of positioning the gas flow passage opening lower, the invention positions it higher than the liquid flow passage opening in the vertical dimension. This spatial rearrangement ensures that gas introduced from the air introduction opening can flow smoothly upward and laterally to the gas flow passage without being obstructed by the liquid flow passage, thereby maintaining both manufacturing ease and gas flow reliability.
3Quantity of substance
If the liquid flow passage extends below the gas flow passage, then the liquid storage capacity is increased, but the gas flow is interrupted and operability during cartridge replacement deteriorates
Solution Approach 1:
The invention rearranges the vertical positions of the flow passages, positioning the gas flow passage opening higher than the liquid flow passage opening. This dimensional reconfiguration allows the liquid flow passage to extend downward for adequate liquid storage while the higher gas flow passage opening ensures unobstructed gas flow, thereby maintaining both liquid storage capacity and cartridge replacement operability.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration enhances the efficiency of gas-liquid substitution, allowing for continuous printing by ensuring smooth ink supply from the cartridge to the sub tank, improves operability during cartridge replacement, and reduces the sub tank's size without compromising storage capacity.
Implementation Method 1
the ink in the cartridge naturally drops via the liquid flow passage and is introduced into the sub tank
Implementation Method 2
gas flows the inside of the sub tank to be supplied to the gas flow passage from the air introduction opening

AI summary
A liquid supplying device includes a tank; and a cartridge configured to be attached to the tank and having a first storage chamber configured to store liquid. The cartridge is formed with a communicating opening in communication with the first storage chamber. The tank has a second storage chamber configured to store the liquid, a liquid passage, a gas passage, a joint, an outer wall, an inner wall, an air communication portion, and a narrow-width portion. The liquid passage is in communication with the second storage chamber and has a first vertical portion. The gas passage has a second vertical portion. The first vertical portion, the second vertical portion, and the air communication portion are arranged in this order in the first direction and a direction away from the fifth end portion.
