Negative-pressure cleaning machine

Abstract

The invention provides a negative-pressure cleaning machine and relates to the field of cleaning equipment. The negative-pressure cleaning machine comprises a rack, a cleaning cabin and a control system and further comprises a liquid feeding mechanism, a steam heating system, a liquid circulating system, a vacuum mechanism and a circulating heater which are controlled to operate by the control system. The liquid feeding mechanism communicates with the cleaning cabin and is used for adding cleaning liquid into the cleaning cabin. The circulating heater comprises a heating box and a heating coil, the heating box is internally provided with a first heating chamber used for heating the liquid, the heating coil is arranged on the surface of the heating box in a sleeving mode, and the first heating chamber communicates with the top of the cleaning cabin. The vacuum mechanism communicates with the cleaning cabin. The negative-pressure cleaning machine generates a large number of bubbles and oscillates constantly through decompression boiling, clean air introduced from the bottom of a cabin body in the vacuum environment is utilized to form the bubbles to impact the surfaces of instruments, the whole process is under control of a program, and it can be guaranteed that the blind-end instruments and other instruments are cleaned without a dead angle; and the negative-pressure cleaning machine can be used for cleaning the high-value-added precise medical instruments which are not easily (or difficultly) cleaned by traditional equipment.

Description

technical field [0001] The invention mainly relates to the field of cleaning equipment, in particular to a negative pressure cleaning machine. Background technique [0002] In actual work, we clean and disinfect various instruments before they can be used again. Common cleaning and disinfection methods are: high-temperature cleaning and disinfection, disinfection liquid cleaning and disinfection. However, some instruments, such as endoscopes (luminal rigid endoscopes), hoses, etc.; the above method can only be used to clean the surface of the instrument, but the interior cannot be cleaned, and the interior of these instruments is more important. In addition, The simple method of cleaning and sterilizing by high temperature heating is completely inapplicable to some instruments that are not resistant to high temperature, especially some relatively expensive (precise) medical instruments, which are often easily damaged by high temperature conditions.

AI Technical Summary

Problems solved by technology

The structure of the cleaning device is simple and reliable, and it can quickly and efficiently clean the narrow cylinder head camshaft cover oil passage thoroughly, but it can only be used to clean the camshaft cover oil passage after the cylinder head is assembled, and the scope of application is single. Moreover, the way of cleaning and disinfecting the cleaning device by high temperature heating is completely inapplicable for some instruments that are not resistant to high temperature
