[0024] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0025] Please refer to the appendix. Figures 1-4 This utility model provides a water quality testing device with a cleaning mechanism, including a water quality analyzer 1, which is electrically connected to a detection probe 2. The detection probe 2 performs water quality testing on the obtained water sample and transmits the detection data to the water quality analyzer 1, thus realizing the function of water quality testing on the water sample. It should be noted that the water quality analyzer 1 and the detection probe 2 are technologies known to those skilled in the art, and their specific structure and principle will not be described in detail. It also includes a cylinder 3, with an end cap 4 threadedly connected to the bottom of the cylinder 3, which is easy to install and remove. A suction tube 5 is fixedly connected to the center of the end cap 4. A control switch 6 is fixedly fixed to the top of the cylinder 3. A detection port 7 is fixedly connected to the bottom of the side of the cylinder 3. The detection probe 2 is inserted and fixed in the detection port 7. An automatic suction component is fixed inside the cylinder 3, and a cleaning component is detachably installed on the automatic suction component.

[0026] The automatic suction assembly includes a first partition 8, which is horizontally fixed above the inside of the cylinder 3. A battery 9 is fixed to the top of the first partition 8. A USB charging port 10 is provided at the top of the side of the cylinder 3, which is electrically connected to the battery 9. The battery 9 is electrically connected to a control switch 6. A second partition 11 is also horizontally fixed inside the cylinder 3. A servo motor 12 is vertically fixed to the top of the second partition 11 and is electrically connected to the control switch 6. The output shaft of the servo motor 12 vertically passes through the second partition 11, and a lead screw 13 is vertically fixed to the bottom of the output shaft. A threaded sleeve 14 is threaded onto the surface of the lead screw 13. Limiting plates 15 are symmetrically fixed to the side of the threaded sleeve 14. Limiting grooves 16 are symmetrically opened on both sides of the inner wall of the cylinder 3. The ends of the two limiting plates 15 away from the threaded sleeve 14 are vertically slidably connected in the two limiting grooves 16. Guide rods 17 are vertically fixed to the bottom of each of the two limiting plates 15, and pistons 18 are fixed to the bottom of the guide rods 17. A rubber ring 19 is fixed to the side surface of the piston 18. The surface of the rubber ring 19 abuts against the inner wall side of the cylinder 3. Specifically, when the operator runs the servo motor 12 through the control switch 6, the servo motor 12 can drive the lead screw 13 to rotate in both directions. Under the combined limiting action of the limit plate 15 and the limit slide groove 16, when the lead screw 13 rotates in both directions, the threaded sleeve 14 threaded to the surface of the lead screw 13 can move up and down, thereby driving the limit plate 15 to move up and down synchronously. The piston 18 can be driven to move up and down inside the cylinder 3 through the guide rod 17. Under the sealing action of the rubber ring 19, when the piston 18 moves up inside the cylinder 3, a negative pressure can be generated in the space below the cylinder 3, so that the suction tube 5 can suck up the water sample to be sampled, thereby realizing the function of automatically sucking up the water sample required for water quality testing. When the water sample is sucked into the cylinder 3, it can enter the detection port 7 and be inserted and fixed in the detection port 7 for water quality testing.

[0027] The cleaning assembly includes a connecting brush plate 20, which is fixed to the center of the bottom of the piston 18 by a fixing screw 21. Several bristles 22 are fixed on the side surface of the connecting brush plate 20, and the bristles 22 abut against the inner wall of the cylinder 3. Specifically, when the piston 18 moves up and down inside the cylinder 3, it can drive the connecting brush plate 20 to move up and down synchronously, so that the bristles 22 can perform brushing and cleaning operations on the inside of the cylinder 3. Since the end cover 4 is easy to disassemble and assemble, the operator only needs to disassemble and assemble the end cover 4, and then disassemble and assemble the connecting brush plate 20 by removing and assembling the fixing screw 21. That is, the equipment can also easily perform automatic cleaning operations on the cylinder 3, and the cleaning structure is easy to disassemble and assemble, making it convenient to replace and use.

[0028] The bottom end of the suction tube 5 is threaded with a filter head 23, and the bottom end of the filter head 23 is fixed with a filter screen 24. Specifically, under the action of the filter head 23 and the filter screen 24, it can effectively filter weeds and other impurities in the water, which is beneficial to the reliability of the test results of the water quality tester 1. The filter head 23 is easy to disassemble and assemble, thus making it easy to replace the filter head 23 and the filter screen 24.

[0029] A rubber sealing ring 25 is fitted at the bottom of the cylinder 3. When the end cap 4 is screwed onto the bottom of the cylinder 3, the rubber sealing ring 25 abuts against the end cap 4 and the cylinder 3. Specifically, under the sealing action of the rubber sealing ring 25, the sealing performance between the end cap 4 and the cylinder 3 can be effectively increased, thereby preventing water leakage.

[0030] A connecting rod 26 is vertically fixed at the top of the cylinder 3, and a handle 27 is fixed at the top of the connecting rod 26. Specifically, the operator can hold the cylinder 3 by the handle 27 and the connecting rod 26, which makes it convenient for the operator to take water samples.

[0031] The usage process of this utility model is as follows: The operator first turns on the control switch 6 to control the servo motor 12 to run, and puts the cylinder 3 into the water. When the servo motor 12 runs, it can drive the lead screw 13 to rotate, which drives the piston 18 to move upward inside the lower part of the cylinder 3. Under the sealing effect of the rubber ring 19, when the piston 18 moves upward inside the cylinder 3, it can generate a negative pressure in the lower part of the cylinder 3, so that the suction tube 5 can suck up the water sample to be sampled, thereby realizing the function of automatically sucking up the water sample required for water quality testing. Under the action of the filter head 23 and the filter screen 24, it can effectively filter weeds and other impurities in the water, which is beneficial to the reliability of the test results of the water quality tester 1. The filter head 23 is easy to disassemble and assemble, which makes it easy to replace the filter head 23 and the filter screen 24.

[0032] When the water sample is drawn into the cylinder 3, it can enter the detection port 7, where the detection probe 2, which is inserted and fixed in the detection port 7, can perform water quality testing on the obtained water sample and transmit the detection data to the water quality analyzer 1, thus realizing the function of water quality testing. After the water sample testing is completed, the operator removes the cylinder 3 and controls the servo motor 12 to rotate in the reverse direction through the control switch 6, which drives the piston 18 to move downward inside the cylinder 3, thereby pushing out the water sample drawn into the cylinder 3.

[0033] Then, the operator places the cylinder 3 into clean water and repeatedly runs the servo motor 12 in both directions to control the piston 18 to move up and down inside the cylinder 3. When the piston 18 moves up and down inside the cylinder 3, it can drive the connecting brush plate 20 to move up and down synchronously, so that several bristles 22 can brush and clean the inside of the cylinder 3. The impurities cleaned by brushing can be sucked into the clean water inside the cylinder 3 for timely cleaning. Therefore, the equipment can conveniently perform automatic cleaning of the cylinder 3. Since the end cover 4 is easy to disassemble and assemble, the operator only needs to disassemble and assemble the end cover 4, and then disassemble and assemble the connecting brush plate 20 by removing and installing the fixing screws 21. That is, the cleaning structure is easy to disassemble and assemble, making it convenient to replace and easy to use.

[0034] The above description is merely a preferred embodiment of this utility model. Any person skilled in the art can modify this utility model or modify it into an equivalent technical solution using the technical solution described above. Therefore, any simple modifications or equivalent substitutions made based on the technical solution of this utility model are within the scope of protection claimed by this utility model.
