Embodiment Construction

[0027] Such as figure 1 As shown, the first specific embodiment of the present invention is: a liquid level detection device for a medical washing machine, including a pressure tube 2 made of metal materials, a pressure sensor 3, and a pagoda-shaped adapter 5 , the connecting pipe 6 made of PU transparent pipe, the display screen 7 and the control system 8 including the PLC controller. In this embodiment, the pressure pipe 2 is connected and fixed on the inner cavity side wall of the washing machine liner 1 by welding In addition, in addition to the welding connection shown in this embodiment, the pressure pipe 2 can also be connected and fixed on the side wall of the washing machine liner 1 by screw connection. When the screw connection is used, it can be A support is set between the pressure tube 2 and the liner 1, and a chute (not shown in the figure) is set on the support, so that the height of the pressure tube 2 relative to the side wall of the liner 1 can be adjusted. ...

Abstract

The invention discloses a liquid level detection device and method for medical cleaners. The device comprises a pressure tube, a pressure sensor, an adapter, a control system, a connecting tube and a display screen. The pressure tube is fixed to the sidewall of an inner container of a cleaner. One end of the pressure tube is open, and the other end of the pressure tube is closed; the open end of the pressure tube is downwardly communicated with the inner container of the cleaner. One end of the adapter is connected with the upper portion of the pressure tube, and the other end of the adapter is connected with the pressure sensor. The pressure sensor is electrically connected with the control system. The connecting tube is disposed between the adapter and the pressure sensor, and the pressure tube is communicated with the pressure sensor through the connecting tube. When liquid level of the inner container of the cleaner changes, pressure of air hermetically enclosed in the pressure tube also changes; the inner pressure of the pressure tube is measured through the pressure sensor, and the control system can calculate the height of liquid level of the inner container and displays the height on the display screen of the cleaner in real time.

Description

technical field [0001] The invention relates to a liquid level detection device and a method for using the device to test the liquid level, in particular to a pressure type liquid level detection device and a test method for a medical washing machine. Background technique [0002] In the medical field, the cleaning and disinfection of medical devices is particularly important. In the process of cleaning medical devices, it is necessary to add a certain proportion of washing enzyme liquid according to the amount of washing water injected into the inner tank of the washing machine to achieve the best Therefore, it is very important to timely measure the liquid volume of the washing water injected into the washing machine. Most of the current medical cleaning machines use floating ball liquid level detection devices. The characteristic of this kind of opening device is that it can only detect the liquid level of one switch or two switches, which cannot meet the timely detection...
