How Trigger Sprayers work

Trigger sprayers, also known as pump sprayers, are commonly used to spray liquid products such as cleaning solutions, pesticides, and water for plants. The trigger sprayer works by using a pump to create pressure within the container holding the liquid, which then forces the liquid out of the nozzle when the trigger is pulled.

Here's a step-by-step breakdown of how a trigger sprayer works:

    The trigger sprayer consists of a bottle or container, a pump mechanism, and a nozzle.
    The pump mechanism is typically made up of a plunger, a piston, and a spring.
    When the trigger is not pressed, the spring in the pump mechanism is in its natural position, and the plunger and piston are at the top of the pump.
    When the trigger is pressed, the plunger is pushed down, which compresses the spring and moves the piston to the bottom of the pump.
    This action creates a low-pressure area in the pump, which draws liquid up from the container through a tube and into the pump chamber.
    As the trigger is released, the spring expands and pushes the plunger and piston back up, which compresses the liquid in the pump and creates pressure within the container.
    When the trigger is pulled again, the pressurized liquid is forced out of the nozzle in a fine mist or stream.


In summary, trigger sprayers work by creating pressure within the container holding the liquid by using a pump mechanism. When the trigger is pulled, the pressurized liquid is forced out of the nozzle in a fine mist or stream.
