Technical Analysis of FEA15 Perfume Crimp Pump: Structural Design, Material Selection, and Fluid Control Principles

1. Structural Design

The FEA15 Perfume Crimp Pump is a precision-designed spray pump primarily used for packaging perfumes and high-end cosmetic liquids. Its key components include:

• Housing: The main structure that secures internal components and provides the pressing stroke.
• Piston: Generates pressure differentials through vertical movement to draw and atomize liquid.
• Spring: Provides rebound force to reset the pump and maintain sealing.
• Dip Tube: Connects the liquid inside the bottle to the pump body for stable delivery.
• Valve Mechanism: A one-way valve design prevents backflow and ensures precise dosing per press.
• Crimp Cap: Secures the pump via mechanical crimping to ensure leak-proof sealing.

The design emphasizes high-precision assembly for uniform spray, no dripping, and compatibility with liquids of varying viscosities.

2. Material Selection

Materials for the FEA15 Crimp Pump must meet chemical stability, durability, and environmental requirements. Common choices include:

• PP (Polypropylene): Used for the housing and piston, offering corrosion resistance and cost efficiency.
• PE (Polyethylene): Used for dip tubes, providing flexibility and resistance to brittleness.
• Stainless Steel Spring: Resists oxidation and fatigue, ensuring long-term elasticity.
• PTFE (Polytetrafluoroethylene): Used for critical seals, offering solvent resistance and low friction.
• Glass or Ceramic Balls: Used in valve systems to enhance sealing precision.

High-end versions may use food-grade or recyclable materials to align with sustainability trends.

3. Fluid Control Mechanism

The FEA15 pump operates based on pressure differentials and mechanical coordination:

1. Pressing Phase: The piston compresses the pump chamber, increasing pressure and forcing liquid through the valve into the atomization channel.
2. Atomization Phase: Liquid passes through a precision nozzle (orifice), forming fine droplets with spray angle and particle size determined by nozzle design.
3. Refill Phase: The spring resets, creating negative pressure to draw liquid from the bottle while the valve closes to prevent backflow.

Key performance parameters include:

• Spray Volume (Dose): Typically 0.1–0.3 mL per spray (customizable).
• Atomization Quality: Influenced by nozzle diameter (0.2–0.5 mm standard) and pump chamber pressure.
• Sealing Performance: Relies on valve and material compatibility to prevent leakage during storage.

The FEA15 Perfume Crimp Pump achieves high-precision atomization and long-term sealing through optimized structure, corrosion-resistant materials, and fluid dynamics. Future trends may focus on miniaturization, replaceable cartridges, and bio-based materials.
