Quick-connect mix chamber assembly for plural component sprayer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Plural component sprayers require complex disassembly for maintenance and swapping of mix chambers, leading to increased downtime and operational inefficiencies, as the entire fluid head must be disassembled to address issues or change mixing configurations.
Innovation Solution
A quick-connect mix chamber assembly that allows the mixer to be mounted and removed as a discrete component, enabling easy installation, removal, and servicing without disassembling other parts of the sprayer, with an air cap design that supports flexible mounting and dismounting and facilitates alignment of inlet and mix bores for efficient mixing and spraying.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If the entire fluid head is disassembled for maintenance or swapping of mix chambers, then access to internal components is improved, but downtime and operational inefficiency increase
Solution Approach 1:
The mixer is divided into separable components: the mix chamber body, inlet bores, and outlet orifice can be removed as a discrete assembly from the fluid head. This segmentation allows maintenance personnel to access and service only the mixing components without disassembling the entire fluid head, thereby reducing downtime while maintaining ease of repair.
2Adaptability or versatility
If the entire fluid head is disassembled to swap mix chambers, then different mixing configurations can be installed, but operational efficiency decreases
Solution Approach 1:
The mix chamber assembly is designed as a modular segment that can be independently removed and replaced. The mix chamber body with its specific bore configurations can be swapped quickly without affecting other fluid head components, enabling rapid reconfiguration for different applications while maintaining high operational efficiency.
Solution Approach 2:
The fluid head is designed with a universal mounting interface that accommodates different mix chamber configurations. The standardized connection allows various mix chambers with different inlet/outlet arrangements to be installed in the same fluid head, providing versatility without requiring complete disassembly and thereby preserving operational efficiency.
3Ease of repair
If complex disassembly procedures are used for maintenance, then complete access to all components is achieved, but maintenance time and operational disruption increase
Solution Approach 1:
The mixer components are segmented into a removable assembly that provides complete access to the mix chamber body, inlet bores, and outlet orifice as a unit. This segmented design allows maintenance personnel to gain full access to all mixing components through a simple removal operation rather than complex disassembly, thereby improving ease of repair while maintaining ease of operation.

AI summary
A mixer (46) for a plural component sprayer is configured to receive first and second component materials and emit a spray of a resulting plural component material. The mixer includes a contoured seal head (120) that is configured to interface with a contoured chamber within a receiver to form a fluid-tight seal therebetween. The mixer receives individual component materials through inlet bores (50a, 50b) formed through the mixer. The component materials mix within a mix bore (52) of the mixer to form a plural component material that is emitted as a spray from an orifice (54) formed in the mixer.
