käsiruisku

Käsiruisku, which translates to "hand sprayer" or "handheld sprayer" in English, is a device used for applying liquids, often in a fine mist or spray. These devices are commonly found in households, gardens, and various professional settings. They typically consist of a reservoir for the liquid, a pump mechanism, and a nozzle that controls the spray pattern and dispersion.

The pump can be operated manually, either by a trigger, a lever, or a piston. When the pump is activated, it creates pressure within the reservoir, forcing the liquid through the nozzle. The design of the nozzle significantly influences the application, allowing for a wide spray for covering large areas or a more concentrated stream for targeted application.

Käsiruisku devices are used for a wide range of purposes. In domestic settings, they are often used for cleaning, applying pest control solutions, or misting houseplants. Gardeners commonly employ them for applying fertilizers, pesticides, herbicides, or simply watering delicate plants. Professionally, similar devices are utilized in industries such as automotive detailing for applying cleaning agents or waxes, and in some types of construction for applying sealants or adhesives.

The simplicity and portability of Käsiruisku make them a versatile tool for many tasks requiring liquid application. Their effectiveness is dependent on the viscosity of the liquid being sprayed and the specific design of the sprayer and its nozzle. Maintenance usually involves cleaning the reservoir and nozzle to prevent clogging.
