This article will comprehensively elaborate on the definition, classification, working principle, structural composition, application fields, technological development and future trends of cleaning machines.

Ii. Definitions and Basic Concepts

A cleaning machine is a device that removes dirt, impurities and contaminants from the surface of objects through physical, chemical or biological means. Its working principle is based on the effects of dissolving, emulsifying, dispersing and peeling dirt. It uses energy forms such as mechanical force, thermal effect, chemical reagents or ultrasonic waves to remove dirt from the surface of objects, thereby achieving the purpose of cleaning. According to application scenarios and technical features, cleaning machines can be classified into various types such as industrial cleaning machines, household cleaning machines, and commercial cleaning machines. Each type is designed for different cleaning needs and has unique performance and advantages.

Iii. Classification and Working Principle of Cleaning Machines

(1) Classification by cleaning technology

Mechanical cleaning machine

Principle: Cleaning is achieved through the friction, impact force or pressure generated by mechanical movement. For instance, drum washing machines use the rotation of the drum to drive the clothes to rub against each other, while high-pressure cleaners use high-pressure water jets to impact the surface of objects and remove dirt.

Application: Widely used in industrial pipeline unblocking, building exterior wall cleaning, vehicle washing and other scenarios, it is suitable for removing stubborn sand, oil stains and rust.

Ultrasonic cleaning machine

Principle: Utilizing the cavitation effect produced when ultrasonic waves propagate in liquids. When ultrasonic waves vibrate liquids at high frequencies, countless tiny bubbles are formed. These bubbles burst rapidly, generating powerful shock waves and micro-jets that strike the surface of objects and peel off dirt.

Application: It is often used for cleaning precision electronic components, optical lenses, medical devices, etc. It can reach into the crevices and blind holes of complex structures to achieve high-precision cleaning.

Chemical cleaning machine

Principle: By means of chemical reagents (such as acids, bases, surfactants, etc.) to undergo chemical reactions with dirt, it is dissolved, emulsified or decomposed. For instance, dishwashers remove grease from tableware with special detergents, and industrial scale removers dissolve scale in the pipes of equipment.

Application: It is suitable for dirt that is difficult to remove by physical means, such as carbon deposits inside industrial equipment and organic residues in biological laboratory vessels.

Steam cleaning machine

Principle: Utilizing the thermal effect and physical impact force of high-temperature and high-pressure steam.
