[0020] The following describes the specific implementation of the present invention in further detail through the description of the embodiments with reference to the accompanying drawings. The purpose is to help those skilled in the art have a more complete, accurate and in-depth understanding of the concept and technical solutions of the present invention, and Contribute to its implementation.
[0021] Such as Figure 1 to Figure 3 As shown, the present invention provides a vacuum level detection system of a scrubber, which includes a controller and a human-machine interaction module connected to the controller, a vacuum pressure sensor, and a storage module. The storage module is arranged on the human-machine interaction module. The sensor is arranged at the sewage suction port of the washing machine, and the sewage suction port is connected with the sewage tank of the washing machine through a sewage suction pipe.
[0022] Specifically, such as figure 1 with figure 2 As shown, the scrubber includes a sewage tank, a wiper rake and a suction fan. The sewage tank is used to store sewage, and the suction fan is used to generate suction. The suction port on the wiper rake is connected to the sewage in a negative pressure state through the sewage suction pipe. The boxes are connected, and the sewage suction port is a water outlet arranged on the top of the wiper rake. The suction fan is fixedly arranged on the sewage tank, and the suction fan is used to vacuum the sewage tank to generate a negative pressure area and form suction, which can suck the sewage left on the ground. After the suction fan is operated, the sewage on the ground reaches the sewage tank through the wiper rake and the sewage suction pipe, and the sewage is finally stored in the sewage tank.
[0023] Such as figure 1 As shown, the man-machine interaction module includes a man-machine panel and a display screen arranged on the man-machine panel. The display screen is preferably a liquid crystal display screen, and the display screen is used to display the detection result and the negative pressure value obtained by the vacuum pressure sensor. The human-computer interaction module also includes the power-on button, the accuracy check button and the mode switch button set on the man-machine panel. Press the power button to control the vacuum detection system to start, and press the accuracy check button to control the vacuum detection system Enter the self-calibration mode. After the self-calibration of the vacuum detection system is completed, the display will show the word "OK". At this time, you can press the mode switch key according to the detection purpose to control the vacuum detection system to select positive pressure detection or negative pressure detection.
[0024] Such as figure 1 As shown, the man-machine panel is provided with a data download interface that is electrically connected to the storage module and used for data download. The storage module is fixedly arranged on the man-machine panel. The storage module is used to automatically store the detection data generated when the vacuum detection system detects each scrubber. The data download interface is preferably a USB interface, which can be downloaded daily or regularly The interface is used to download and analyze the test data.
[0025] When using the vacuum degree detection system of the present invention to detect the vacuum degree of the scrubber before leaving the factory, first install the vacuum pressure sensor at the suction port, then turn on the scrubber, and the suction fan starts to run to pump the sewage tank. Vacuum; the vacuum pressure sensor transmits the negative pressure value detected at the suction port to the controller, and the controller controls the human-computer interaction module to display the negative pressure value. The negative pressure value is displayed on the display, and the inspector can observe the negative pressure value. Then the controller judges whether the negative pressure value detected by the vacuum pressure sensor meets the set value, and controls the human-computer interaction module to display the detection result. If the controller judges that the negative pressure value detected by the vacuum pressure sensor meets the set value, it will control the human-computer interaction module to display the detection result as "PASS", indicating that the currently detected vacuum of the scrubber meets the requirements and can generate sufficient suction , In line with factory standards. If the controller determines that the negative pressure value detected by the vacuum pressure sensor does not meet the set value, it will control the human-computer interaction module to display the detection result as "NG", indicating that the currently detected vacuum of the scrubber does not meet the requirements and cannot be generated. Sufficient suction power does not meet the factory standard and needs to be reworked for debugging.
[0026] The present invention also provides a method for detecting vacuum degree of a scrubber, which adopts the vacuum degree detection system of a scrubber with the above-mentioned structure, and includes the following steps:
[0027] (1) The suction fan operates to vacuum the sewage tank;
[0028] (2) The vacuum pressure sensor transmits the negative pressure value detected at the suction port to the controller, and the controller controls the man-machine interaction module to display the negative pressure value;
[0029] (3) The controller judges whether the negative pressure value detected by the vacuum pressure sensor meets the set value, and controls the human-computer interaction module to display the detection result.
[0030] In step (3), if the controller determines that the negative pressure value detected by the vacuum pressure sensor meets the set value, it controls the human-computer interaction module to display the detection result as "PASS"; if the controller determines that the negative pressure detected by the vacuum pressure sensor If the pressure value does not meet the set value, the human-computer interaction module is controlled to display the test result as "NG".
[0031] The present invention has been exemplarily described above with reference to the drawings. Obviously, the specific implementation of the present invention is not limited by the foregoing manner. As long as various insubstantial improvements are made by adopting the method concept and technical solution of the present invention; or without improvement, the above-mentioned concept and technical solution of the present invention are directly applied to other occasions, all within the protection scope of the present invention within.
