Milking Cup Ventilation Device with Fixed Annular Body
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing milking systems face hygiene issues due to the risk of germ contamination from lost or reinserted ventilation plugs, which can disrupt the milking process and lead to milk escape or blockages.
Innovation Solution
A secure ventilation device with an annular body fixed on the milk hose, featuring a nozzle opening and a passage that communicates with the hose interior, preventing accidental reinsertion of contaminants and ensuring a tight fit to prevent milk escape, is designed. The annular body is securely positioned and cannot be lost, with a design that avoids turbulence and facilitates easy cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an insertable ventilation plug is used in the milk hose, then ventilation function is achieved, but hygiene is compromised due to risk of loss and reinsertion with germs
Solution Approach 1:
The invention extracts the removable plug from the system and replaces it with a fixed annular body integrated into the milk hose. The ventilation function is maintained through a fixed nozzle opening in the annular body, eliminating the risk of plug loss and reinsertion contamination while preserving the essential ventilation capability.
Solution Approach 2:
The annular body is merged with the milk hose structure, creating an integrated assembly where the ventilation device becomes an inherent part of the hose rather than a separate removable component. This merging ensures the ventilation opening remains permanently sealed and hygienic while maintaining functionality.
2Ease of operation
If a removable ventilation plug is used, then installation flexibility is improved, but device integrity is worsened due to potential loss and contamination
Solution Approach 1:
The annular body is pre-installed and fixed onto the milk hose during manufacturing or initial setup, creating a permanent integrated structure. This preliminary action eliminates the need for repeated installation/removal operations, maintaining system integrity while achieving the necessary ventilation function from the outset.
3Productivity
If a ventilation opening with larger diameter is used, then ventilation efficiency is improved, but risk of contamination and blockages increases
Solution Approach 1:
The invention applies local quality by creating a differentiated structure with a small-diameter nozzle opening (0.5mm) in the annular body that communicates with a larger-diameter passage (3mm) in the milk hose. This local differentiation allows the ventilation opening to be small and contamination-resistant while the larger internal passage maintains ventilation efficiency.
Solution Approach 2:
The invention resolves the diameter contradiction by transitioning to another dimension - creating a multi-dimensional flow path where the small nozzle opening (first dimension) connects to a larger passage (second dimension) through the wall thickness. This dimensional transition allows both small opening benefits and large passage benefits to coexist.

AI summary
The invention relates to an arrangement comprising a rubber teat (1), a milking tube (8) that is connected to the rubber teat (1), and a ventilating device (10). The arrangement has a flow path for discharging milked milk, said flow path communicating with the outside atmosphere via the ventilating device (10). The arrangement is characterized in that the ventilating device (10) comprises a ring body (11) with a nozzle opening (12), said ring body (11) being fixed on a straight section of the milking tube (8) in a position in which the ring body (11) rigidly embraces the milking tube (8) and the nozzle opening (12) communicates with the flow path in a tube interior (20) of the milking tube (8).
