Do I need to consider the liquid discharge method when choosing a plastic pump head?

When choosing a plastic pump head, the liquid outlet method must be considered, as it directly affects the effectiveness of liquid use, user experience, and adaptability to application scenarios. The following is a detailed introduction to the "liquid outlet method" from different perspectives:

1、 Different liquid extraction methods are suitable for different liquids
● Spray type
→ Suitable for low viscosity liquids, such as alcohol, perfume, air freshener, etc.
→ Features: Delicate liquid output, wide coverage, conducive to rapid evaporation and uniform distribution.
● Press and release type (continuous liquid discharge)
● Suitable for medium viscosity liquids such as hand sanitizer, shampoo, shower gel, etc.
→ Features: Large liquid output, easy to press, suitable for frequent daily use.
● Foam type (direct output of foam)
→ Suitable for foam hand sanitizer, face cleaning mousse and other liquid with strong foaming property.
→ Features: No need to rub the foam with hands. The foam is soft and delicate, saving consumption.
● Drip/control type (quantitative drip)
→ It is suitable for essential oil, eye drops, essence and other products requiring precise dosage control.
→ Features: Low and precise liquid output, suitable for high-value liquids.

2、 The discharge method affects the user experience
● Operational convenience
→ The spray and foam pump heads are mostly operated by one hand, which is convenient and fast.
● The drip pump head is more suitable for scenarios with small doses and multiple uses.
● Control force and accuracy
● Control the precise discharge of the pump head to avoid waste.
● The ordinary press pump head has a relatively rough discharge, suitable for household occasions.
● Safety and hygiene
→ The spray pump head is often equipped with a dust cover or locking structure to avoid accidental spraying and pollution.
→ The foam pump head shall not touch the liquid repeatedly, which is helpful for hygienic use.

3、 The discharge method affects the liquid effect
● Spray is more conducive to uniform coverage: if used for disinfection or fragrance, it can cover a wide range of surfaces or air.
● Foam is more convenient for cleaning, covering and saving use: when used for hand sanitizer, it saves liquid and is convenient for washing.
● Quantity control is more conducive to precise use: suitable for precious liquids or cosmetics and pharmaceuticals with dosage requirements.

4、 The discharge method affects the structural design of the pump head
● Spray pump head shall be equipped with atomization hole and air mixing chamber
● Foam pump head has foam generating cavity structure
● The design of the pump head focuses on the spring rebound force and liquid output
● The drip pump head requires a precise valve control structure

5、 The discharge method determines the matching bottle type of the pump head
● Spray pump head is commonly used for small volume bottles (such as 30ml, 60ml)
● Press the pump head with multiple medium to large capacity bottles (such as 250ml, 500ml)
● Drip pump heads are often equipped with small bottles such as essential oil bottles and glass bottles
● The bottle mouth of foam pump head is large, and the bottle body is generally wide and stable
