  • the water in the washing tank 2 can be heated. Therefore, in the embodiment, a heating device is further added to the outer wall of the washing tank 2, or the heating device is externally disposed to pass through the water inlet valve 701 and the water inlet.
  • the water entering the cleaning tank 2 is directly hot water.
  • the temperature sensor is also provided in the washing tank 2 in this embodiment. 9. The temperature sensor can be disposed at the bottom or the middle of the left side of the cleaning tank 2.
  • the temperature sensor 9 is electrically connected to the touch screen 601 and the switching power supply 603, and can display the measured temperature value in the touch screen 601.
  • the ultrasonic cleaning machine for the hard endoscope when operated, there are mainly three stages, namely, a preparation stage, a cleaning stage, and a self-cleaning stage.
  • a preparation stage When the hard endoscope type lumen device is cleaned, water is added in the preparation stage. , self-test and exhaust procedures.
  • the self-test is a part of the control system.
  • the main function is that the cleaning machine performs internal function detection. All components such as the twelve-position valve 501, the peristaltic pump 502, and the differential pressure switch 504 are sequentially activated to receive the seal inspection of the adapter 505.
  • Flow meter 503 The flow count is consistent with expectations, indicating that the seal is normal and then enters the exhaust function.
  • Exhaust is an ultrasonic system that removes air from the water to improve the ultrasonic cleaning effect.
  • the ultrasonic cleaning machine for the hard endoscope improves the existing cleaning method, instead of the manual cleaning of the prior art, and can simultaneously clean twelve hard-mirror lumen instruments at one time, which greatly saves the economy. Human and material resources improve the efficiency of instrument cleaning.
  • the ultrasonic cleaning machine can quickly remove the dirt on the inner and outer surfaces, cracks, blind holes, etc. of the instrument, thereby achieving the purpose of cleaning, and thoroughly cleaning the parts that cannot be cleaned by other cleaning methods.
  • the ultrasonic technology combined with the new cleaning machine suction system, through the circulation of water flow can greatly improve the internal cavity cleaning effect of the rigid endoscope type lumen device.
