Description

Technical Field

[0001] The invention relates to the technical field of cleaning machines, in particular to a carbon dioxide cleaning machine. Background Art

[0002] Carbon dioxide cleaning machine is an environmentally friendly and pollution-free cleaning equipment. It uses carbon dioxide as the cleaning medium and has a unique structure and principle. The structure of this cleaning machine is mainly composed of a compression system, a refrigeration system, a cleaning system, a circulation system and a control system. The carbon dioxide cleaning machine has achieved an efficient and environmentally friendly cleaning solution through its unique working method. It is suitable for various fields, especially playing an important role in the industrial field.

[0003] The working principle of the carbon dioxide cleaning machine is mainly to utilize the sublimation process of solid carbon dioxide (dry ice) and the high-speed injection of carbon dioxide gas to achieve fast, efficient and residue-free cleaning of objects. First, the dry ice cleaning machine uses high-pressure air to spray dry ice particles onto the working surface to be cleaned, and uses the physical reaction of temperature difference to make different substances separate at different shrinkage speeds. When the dry ice particles at -78 degrees Celsius come into contact with the surface of the dirt, a brittle explosion phenomenon will occur, causing the dirt to shrink and loosen. The dry ice particles will instantly vaporize and expand 800 times, generating a strong peeling force, which will quickly and thoroughly remove the dirt from the surface of the object, achieving a fast, efficient, safe and energy-saving cleaning effect.

[0004] The spray gun and nozzle are important components of the carbon dioxide cleaning machine. At present, the spray gun and nozzle of the existing carbon dioxide cleaning machine need to be operated by the user. Since the carbon dioxide cleaning machine will spray high-speed dry ice from the nozzle when in use, the dry ice will produce a large reaction force when sprayed onto the work surface that needs to be cleaned. Therefore, the user needs a large grip to hold the spray gun steadily. Over time, the user's arm will ache and he will have to stop and rest, so that the cleaning cannot be carried out continuously for a long time, the flushing efficiency is reduced, and the arm pain will cause the spray gun to be unstable, reducing the cleaning quality.
