What are the differences in the spray patterns of different foam spray triggers

As a key equipment in the fields of industrial, household cleaning and personal care, the foam spray trigger has a variety of spray modes to meet different usage scenarios and user needs. The spray mode not only affects the shape, coverage and spray efficiency of the foam, but also determines the application effect and user experience of the product.

Straight spray mode
The straight spray mode is the most basic spray mode. The nozzle sprays the foam in a concentrated columnar form, with a long spray distance and stable flow, which is suitable for accurately covering the target surface.
Application characteristics
It is suitable for occasions where foam needs to be sprayed accurately to a specified position, such as local cleaning of the car surface, maintenance of industrial equipment, etc.
The foam concentration is high and the adhesion is strong, which is convenient for deep cleaning and decontamination.
Structural design points
The nozzle diameter is small, the gas-liquid mixing chamber is compactly designed, and air incorporation is reduced to ensure tight foam molding.
The piston pump pressure control is precise to ensure high-speed liquid spraying.
Advantages and disadvantages analysis
The advantages are long spray distance and precise operation; the disadvantages are small coverage area and low efficiency during continuous spraying.

Fan-shaped spray mode
The fan-shaped spray mode evenly distributes the foam into a wide fan shape with a wide spray range, which is suitable for large-area spraying needs.
Application characteristics
Common in scenes such as indoor wall disinfection, gardening spraying and public area cleaning.
The foam covers a large area, sprays evenly, and reduces repeated spraying.
Structural design points
The nozzle adopts a flat opening design, and the air diversion channel is wide to enhance the gas-liquid mixing effect.
The pump body pressure and flow are more balanced than linear spraying to ensure uniform foam density.
Advantages and disadvantages analysis
The advantages are large coverage and high spraying efficiency; the disadvantages are relatively short spraying distance and slightly low foam concentration.

Atomization spray mode
The atomization spray mode uses a high-pressure pump and a special nozzle to refine the liquid into extremely small particles to form a light and delicate foam mist spray.
Application characteristics
Suitable for sensitive surface care, plant spraying and indoor air humidification.
The foam particle size is extremely small, the coverage is even, and the penetration is strong.
Key points of structural design
The nozzle adopts a porous or microporous design, and cooperates with the output of a high-pressure pump to achieve full atomization of the liquid.
The air mixing ratio is precisely adjusted to ensure the stability of the foam.
Analysis of advantages and disadvantages
The advantages are fine spray and uniform coverage; the disadvantages are limited spray distance and high equipment cost.

Pulse spray mode
The pulse spray mode uses the intermittent operation of the pump body to produce intermittent foam spray, improve the spraying effect and save liquid consumption.
Application characteristics
Commonly used in agricultural spraying, industrial surface coating and disinfection sites.
The spray has a sense of rhythm, reduces liquid waste and improves spraying uniformity.
Key points of structural design
The pump body design supports high-frequency pulse output, and the valve responds quickly.
The pulse frequency and spray time can be adjusted to meet different usage requirements.
Analysis of advantages and disadvantages
The advantages are saving liquid and improving efficiency; the disadvantages are complex structure and high maintenance requirements.

Rotary spray mode
The rotary spray mode uses the internal rotating mechanism of the nozzle to form a rotating spray of the sprayed foam, enhancing the coverage and foam adhesion.
Application features
Mostly used for car washing, surface treatment of industrial equipment and large-area disinfection.
The foam is sprayed in a rotating flow form, with more uniform coverage and strong adhesion.
Key points of structural design
The nozzle has a built-in rotating impeller or eccentric wheel mechanism to drive the nozzle to rotate.
The wear-resistant design of the structure ensures long-term stable operation.
Advantages and disadvantages analysis
The advantages are uniform spraying and wide coverage; the disadvantages are complex mechanical structure and high manufacturing cost.

Mixed multi-mode spraying
Some high-end foam spray triggers support multiple spray mode switching to meet diverse needs. Through mechanical or electronic control, fast switching of spray modes such as straight line, fan shape, and atomization can be achieved.
Application features
Adapt to complex environments and multi-functional needs, such as home cleaning and industrial disinfection.
Users can flexibly choose the spray mode according to the scene.
Key points of structural design
Integrated multi-nozzle design, with intelligent control module.
The spray mode switching is accurate to ensure stable foam quality in each mode.
Advantages and disadvantages analysis
The advantages are flexible and multi-purpose, which improves user experience; the disadvantages are complex structure and increased maintenance difficulty.
