Retractable Liquid Dispenser Nozzle for Contamination Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid product dispensers suffer from poor control over the direction of product emission and the risk of users interfering with the outlet nozzle, leading to inefficient distribution and potential contamination.
Innovation Solution
The dispenser features an outlet nozzle oriented in the longitudinal direction that abuts against a part of the outer shell upon activation, coupled with a drive mechanism that retracts and extends the nozzle, allowing precise control and preventing finger interference by mimicking a pen-like activation mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the outlet nozzle is exposed and accessible for dispensing, then the ease of operation is improved, but the risk of finger interference and contamination increases
Solution Approach 1:
The outlet nozzle is nested within the outer shell during storage and non-use periods. The nozzle can be axially retracted into the outer shell to a storage position where it is protected from finger interference and contamination. During use, the nozzle extends outward from the outer shell to enable dispensing. This nesting arrangement allows the nozzle to be both protected when not in use and accessible when needed.
2Object-affected harmful factors
If the outlet nozzle is retracted into the outer shell for protection, then contamination risk is reduced, but the ease of operation and accessibility deteriorates
Solution Approach 1:
The outlet nozzle is designed to be dynamically movable between two positions: a retracted storage position within the outer shell for protection, and an extended use position for accessibility. The drive mechanism enables the nozzle to transition between these positions, allowing the system to adapt its state based on operational requirements. This dynamic arrangement resolves the contradiction by providing both protection and accessibility at different times as needed.
3Reliability
If a complex drive mechanism is used to control nozzle retraction and extension, then precise control and contamination prevention are improved, but the device complexity increases
Solution Approach 1:
The drive mechanism serves multiple functions: it controls the axial retraction and extension of the outlet nozzle, operates the dispensing action, and maintains the nozzle in appropriate positions for both storage and use. By consolidating these functions into a single integrated mechanism, the patent achieves precise control and contamination prevention without excessively increasing device complexity. The mechanism is actuated by a simple pushing motion on the outer shell, making it user-friendly despite its multifunctional nature.

AI summary
The invention relates to a liquid product dispenser including a tank (8), a dispensing head (9) mounted at one end (8b) of the tank, said dispensing head comprising an outlet nozzle (3), an outer shell (4) containing the tank (8), and a driving part (13) which is capable of axially moving the tank (8) and which is mounted so as to be rotatable between a storage position and a use position. The outlet nozzle (3) has an outlet (3a) oriented in the longitudinal direction, and is suitable for axially engaging with a portion (17c) that is rigidly connected to the outer shell during the actuation of the dispensing head in the use position of the dispenser, and the first end (8a) of the tank is connected to a pusher (2) via a driving mechanism (12) suitable for selectively retracting the pusher (2) and the outlet nozzle (3) into the outer shell (4), and for axially extracting same from the outer shell.
