Problem
Existing ESI sprayer connection methods require additional jigs, increasing the number of components and the outer diameter of the connecting point, leading to instability in ion production efficiency due to variable connection gap lengths.
Innovation Solution
A pipe connecting jig with a conductive cylindrical body featuring a through-hole and a ring-shaped gap forming protrusion, allowing for direct connection of insulator pipes without additional jigs, ensuring a constant connection gap length for stable voltage application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If additional jigs are used to connect insulator pipes, then the connection is achieved, but the number of components increases and the outer diameter of the connecting point increases
Solution Approach 1:
The patent combines the connection function and the gap formation function into a single jig structure. The jig includes a through-hole for pipe passage and a protrusion that simultaneously serves as both the connection interface and the gap-defining element, eliminating the need for separate connection components.
Solution Approach 2:
The jig is designed to perform multiple functions: it provides mechanical connection between pipes, defines the connection gap length through its protrusion structure, and maintains electrical insulation. This multi-functional design reduces the overall component count while achieving the connection objective.
2Ease of manufacture
If additional jigs are used to connect insulator pipes, then the connection is achieved, but the outer diameter of the connecting point increases
Solution Approach 1:
The connection function and gap formation function are merged into a single integrated jig structure, eliminating the need for multiple separate components that would increase the overall diameter of the connecting assembly.
3Device complexity
If the connection gap length varies, then the structure is simple, but the ion production efficiency becomes unstable
Solution Approach 1:
The jig is pre-designed with a specific protrusion length that determines the connection gap length before the actual pipe connection takes place. This preliminary structuring ensures that when pipes are connected, the gap length is automatically controlled to a precise value, guaranteeing stable ion production efficiency.
Solution Approach 2:
The invention controls the critical parameter of connection gap length by changing the geometric parameter of the jig's protrusion. By carefully designing the protrusion length, the connection gap is precisely controlled, which directly affects and stabilizes the ion production efficiency.
4Adaptability or versatility
If a single jig is used to connect pipes of different diameters, then the adaptability increases, but the precision of connection gap control may decrease
Solution Approach 1:
The jig is designed with universal adaptability to accommodate pipes of different diameters while maintaining precise gap control. The through-hole and protrusion structure can interface with various pipe sizes, yet the critical protrusion length that defines the gap remains constant, ensuring precision is maintained across different applications.

AI summary
In an ESI sprayer including a pipe connecting jig used to connect an inlet-side pipe and an ESI capillary, a through-hole having an inner diameter corresponding to an outer diameter of the inlet-side pipe at one end and an inner diameter corresponding to an outer diameter of the ESI capillary at another end is formed in an axial direction of a conductive cylindrical body in which at least both ends are plastically deformable, and a gap forming protrusion protruding inward from a circumferential wall of the through-hole is provided in the cylindrical body.
