[0040] As a further solution of the present invention, the first interface of the water supply cylinder 51 is connected to the last end of the second solenoid valve 26 through a hose for design connection requirements.

[0041] Working principle: When testing the water quality of the water area, the handle 16 in the main unit 1 can be used to make the main box 11 vertical, that is, the box cover 13 is facing upward, that is, the liquid extraction cylinder 22 is also vertical, and the liquid extraction tube 44 is facing vertically downward; then, the first electric slide rail 31 in the cleaning unit 3 can be controlled by the touch screen 15 through the power supply of the battery 14 to drive the push arm 32 to move upward from the bottom, and the push arm 32 will pass through the fitting opening 6 of the partition 12 to insert the liquid extraction tube 44 into the water to be tested, thereby achieving The piston 33 is driven to move upward from the bottom of the liquid extraction tube 44 supported by the support 21 to generate suction, and the liquid is extracted through the liquid extraction tube 44 through the third solenoid valve 43 into the liquid extraction cylinder 22; when the piston 33 moves upward to extract the test liquid, the first solenoid valve 25 on the sealing cover 24 is opened to exhaust the left end of the liquid extraction cylinder 22; and the second solenoid valve 26 is closed to prevent the water supply cylinder 51 from being connected to the liquid extraction cylinder 22, and at the same time, the connection end of the third solenoid valve 43 and the fourth solenoid valve 54 is in a closed state;

[0042] After extraction, the liquid gathers in the right end of the liquid extraction cylinder 22, and the two ends of the liquid extraction cylinder 22 are respectively shielded and sealed by means of the sealing cover 24 and the front end of the regulating baffle 42 in the control unit 4; at this time, the detection liquid contacts the integrated detection probe 23 for detection and is displayed on the touch screen 15; because the two sides of the battery 14 in the main box 11 are respectively shielded and sealed by the partition 12 and the box cover 13, it is prevented that when the liquid is extracted, the detection liquid passes through the pipe groove 9 or the sewage outlet 8 into the main box 11 to cause an impact;

[0043] After the test, the piston 33 can be driven to move again to discharge the extracted test liquid through the liquid extraction tube 44; after the test liquid is discharged, the third solenoid valve 43 is controlled to close the connection end of the liquid extraction tube 44, the third solenoid valve 43 is connected to the fourth solenoid valve 54, and the connection end of the fourth solenoid valve 54 and the second solenoid valve 26 is controlled to be closed;

[0044] Then, the piston 33 is controlled to move to extract the clean water in the water supply cylinder 51 in the water supply unit 5 into the liquid extraction cylinder 22. As the piston 33 moves and the extraction process is controlled, the motor 35 in the piston 33 is driven by the side baffle 34 to seal the piston 33, driving the brush 36 to rotate and scrub the inner wall of the liquid extraction cylinder 22 and rinse it with clean water;

[0045] Since the piston 33 has a certain width, the end of the liquid extraction cylinder 22 sealed by the sealing cover 24 cannot be completely cleaned by the brush 36, and the brush 36 cleans the inner wall of one end of the integrated detection probe 23; after cleaning, the piston 33 is reset and moved, and the third electromagnetic valve 43 is connected and closed with the fourth electromagnetic valve 54, so that the clean water after brushing and rinsing can be discharged through the liquid extraction pipe 44; at the same time, the second electromagnetic valve 26 is opened to connect with the fourth electromagnetic valve 54, and while the clean water is discharged, the clean water of the water supply cylinder 51 is drawn into the top of the liquid extraction cylinder 22 by the suction force of the movement of the piston 33, that is, into the end sealed by the sealing cover 24, and after the clean water after brushing is discharged, the device can be turned 180 degrees, so that the liquid extraction pipe 44 is directed upward, and the box cover 13 is directed downward to shake the device to perform auxiliary flushing on the end of the liquid extraction cylinder 22 that the brush 36 cannot reach;

[0046] At this time, the piston 33 is located in the liquid pumping cylinder 22 close to the adjustment baffle 42, that is, the second electric slide rail 41 is controlled to drive the adjustment baffle 42 to move, so that the collecting cylinder 45 is connected to the liquid pumping cylinder 22, and the piston 33 is moved again for a certain distance to push the dirt to the collecting cylinder 45, and then the liquid pumping tube 44 is connected to the liquid pumping cylinder 22 again; when the liquid pumping tube 44 is connected to the liquid pumping cylinder 22 again, the liquid pumping tube 44 will move in the pipe groove 9, and the collecting cylinder 45 is passed through the sewage outlet 8 by means of the second electric slide rail 41 to process the dirt;

[0047] Then, the piston 33 is controlled again to connect the clean water of the shaking cleaning to the first interface of the water supply cylinder 51 through the second solenoid valve 26 for reflux, and the connection between the second solenoid valve 26 and the fourth solenoid valve 54 needs to be closed, so that the clean water can be refluxed into the water supply cylinder 51 and located above the filter screen 53; when the above cleaning process is reciprocated, the water can be filtered by the filter screen 53 and then drawn to the two ends of the liquid extraction cylinder 22 for use;

[0048] Since the water supply cylinder 51 and the mounting opening 7 of the box cover 13 are detachably mounted, the water supply cylinder 51 can be easily disassembled and cleaned, and the cylinder cover 52 can be rotated to add clean water or clean the dirt trapped by the filter 53; the clean water in the water supply cylinder 51 can also be extracted and stored through the liquid extraction pipe 44 before being tested;

[0049] The above operation can be used to continuously detect two water qualities by extracting and discharging at both ends of the liquid extraction cylinder 22, and one of the water qualities can be stored in the water supply cylinder 51. It can also be used to detect data after mixing multiple water qualities. For example, one of the water qualities is first extracted and stored in the water supply cylinder 51, and then another water quality is extracted into the liquid extraction cylinder 22 to detect the data. After discharging a certain amount, the water in the water supply cylinder 51 is extracted into the liquid extraction cylinder 22 for mixing and the data change is detected again.

[0050] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
