Referring to fig. 1 and 2, the embodiment of the utility model provides an endoscope leak detection appearance, this endoscope leak detection appearance mainly include air pump 10, ooff valve, atmospheric pressure input pipeline 61, atmospheric pressure output pipeline 62, sensor 30, manometer 40, relief valve 50, control circuit board 70, keypad 71, display screen 72 and alarm 73 are constituteed.
Specifically, the air pump 10 is used as an air source, and the switching valve includes an input end and an output end. The air pressure input line 61 is connected between the air pump 10 and the input of the on-off valve. The air pressure output pipeline 62 includes a first end and a second end, the first end is connected to the output end of the switch valve, the second end is communicated with the endoscope 80 to be tested, and the air flow output by the air pump 10 is filled into the endoscope 80 to realize pressurization.
Meanwhile, the sensor 30, the pressure gauge 40 and the pressure relief valve 50 are connected between the first end and the second end of the air pressure output line 62. The sensor 30 is used for acquiring the pressure value of the air pressure output pipeline 62, the pressure gauge 40 is used for reflecting the pressure value of the air pressure output pipeline 62 in real time, and the pressure release valve 50 keeps a closed state in the process of inflating the endoscope 80.
The control circuit board 70 is electrically connected to communicate with the on-off valve, the sensor 30, and the relief valve 50. The keypad 71 is electrically connected to the control circuit board 70 for communication. The key board 71 is provided with a plurality of selection keys, and each selection key corresponds to a preset pressure test value and pressure maintaining duration. The specific parameter values of the pressure test value and the pressure maintaining time period depend on the brand type of the endoscope 80 to be tested.
The brand of the endoscope 80 to be tested is determined, the corresponding selection key is selected on the key board 71, and the corresponding pressure test value and the pressure maintaining time length are sent to the control circuit board 70. The air pump 10 is started, the control circuit board 70 controls the switch valve to open, and the air pump 10 inflates the endoscope 80. Because the sensor 30 and the control circuit board 70 realize communication, when the pressure value detected by the pressure sensor 30 reaches the standard of the pressure test value, the pressure value is timely fed back to the control circuit board 70, and the control circuit board 70 sends a signal to control the on-off valve to be closed. At this time, the pressure maintaining state is entered, and the endoscope 80 is pressurized at a specific pressure value for a corresponding time period.
The endoscope leak detector also comprises a display screen 72 and an alarm 73 which are electrically connected with the control circuit board 70. The display screen 72 is used for displaying the air pressure value inside the endoscope leak detector and various working conditions. The alarm 73 is provided with a trigger threshold, namely after the pressure maintaining time is over, if the sensor 30 monitors that the reduction amount of the internal air pressure value reaches 1.55KPa, the alarm 73 is triggered to remind the endoscope 80 of leakage.
After the pressure maintaining time is over, the control circuit board 70 controls the relief valve 50 to open to realize air relief.
Because be provided with a plurality of selection buttons on the keypad 71 of being connected with control circuit board 70 electricity, every selection button has corresponded different scope 80 brands, combine the atmospheric pressure value that different scope 80 brands can bear, every selection button presets pressure test value and the pressurize of having mutual difference for a long time in advance, and then increased this scope leak hunting detector and carried out the adaptability that the detection leaks hunting to different scope 80 brands, avoid appearing damaging scope 80 or testing inaccurate problem and appearing.
In this embodiment, the on-off valve is a solenoid valve 20. In addition, the components involved in the present embodiment, such as the control circuit board 70, the display screen 72, the alarm 73, the air pump 10, the on-off valve, the sensor 30, the pressure gauge 40, and the pressure relief valve 50, are all of conventional types, and it is within the ability of those skilled in the art to select the corresponding signals according to actual requirements.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made without departing from the gist of the present invention within the scope of knowledge possessed by those skilled in the art.
