Liquid Supply System With Screw Engagement Mechanism

The liquid bottle's outer sleeve is designed with a screw portion that automatically engages with the tank's sleeve when the bottle is inserted. The screw thread structure enables self-alignment and self-securing, allowing the bottle to connect to the tank without manual gripping or additional fastening operations. The system serves itself by using the insertion motion to automatically trigger the screw engagement mechanism.

The manual gripping and holding action is replaced by a mechanical screw engagement system. The screw portion on the outer sleeve converts the linear insertion motion into rotational engagement, automatically securing the bottle to the tank. This mechanical substitution eliminates the need for continuous manual control during the supply process.

The engagement structure uses asymmetric positioning of the screw portion and engagement portions on the sleeve. Each tank type has a unique sleeve configuration that only matches its corresponding liquid bottle type. This asymmetric design ensures that a bottle can only be securely inserted into its designated tank, preventing erroneous insertion while maintaining ease of use for correct pairings.

Different tank types have locally differentiated engagement features on their sleeves, such as varying positions, numbers, or configurations of engagement portions. This local differentiation allows each tank-bottle pair to have specific compatibility characteristics, ensuring that only the correct liquid type can be inserted into each tank while maintaining overall system versatility.
