[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] like Figures 1 to 4 As shown, a biological testing device for domestic water includes a housing 1. A drain outlet 19 is provided at the lower end of the housing 1. A testing box 4 is installed on the lower inner wall of the housing 1. Electric valve pipes 5 are inserted and connected to the left and right ends of the testing box 4. Both sets of electric valve pipes 5 extend to the outer side of the housing 1. A through hole 6 is provided at the upper end of the testing box 4. A horizontal plate 11 is installed at the rear end of the testing box 4. A circular cylinder 12 is fitted inside the horizontal plate 11. The circular cylinder 12 is hollow inside. Several sets of nozzles 13 are inserted and connected inside the circular cylinder 12. A connecting plate 8 is provided on the upper side of the testing box 4. Two sets of water quality testing probes 7 are installed at the lower end of the connecting plate 8.

[0025] A driving component 9 is installed on the upper inner wall of the housing 1. The driving component 9 is used to drive the connecting plate 8 to rotate. The driving component 9 includes a first motor 20 and an electric cylinder 21. The first motor 20 is installed on the upper inner wall of the housing 1. A protruding rod 23 is fixedly connected to the output end of the first motor 20. Several sets of protrusions are provided on the outer surface of the protruding rod 23. While the protrusions drive the sleeve rod 24 to rotate, the sleeve rod 24 can move up and down. The sleeve rod 24 is movably sleeved on the outer surface of the protruding rod 23. The electric cylinder 21 is fixedly sleeved inside the housing 1. A movable plate 22 is movably sleeved on the outer surface of the sleeve rod 24 through a bearing. The sleeve rod 24 can rotate within the movable plate 22. The movable plate 22 can simultaneously drive the sleeve rod 24 to move up and down. The output end of the electric cylinder 21 is fixedly connected to the movable plate 22. Figure 2 and Figure 3 As shown.

[0026] A second motor 14 is installed at the lower end of the horizontal plate 11. The output end of the second motor 14 movably passes through the upper end of the horizontal plate 11 and is fixedly connected to a gear 15. The gear 15 meshes with a ring gear 16, which is fixedly sleeved on the circular cylinder 12. A water inlet pipe 17 is connected to the lower end of the circular cylinder 12. As the circular cylinder 12 rotates, the position of the water inlet pipe 17 changes. In order to deliver the cleaning fluid into the rotating circular cylinder 12, a rotary joint 18 is connected to the lower end of the water inlet pipe 17. The rotary joint 18 is installed on the housing 1. Figure 4 As shown.

[0027] The front end of the enclosure 1 is hinged to a door 2, and a controller 3 is installed on the door 2. The controller 3 is electrically connected to electrical equipment, such as... Figure 1 As shown.

[0028] In practice:

[0029] In use, connect the left electric valve pipe 5 to the domestic water pipe, open the left electric valve pipe 5 to deliver domestic water to the testing box 4, and then use the front water quality testing probe 7 to test the microbial content of the water inside the testing box 4. After the test is completed, open the right electric valve pipe 5 to drain the water. After the water is completely drained, open the left electric valve pipe 5 to deliver other domestic water to the testing box 4. Then, control the two sets of water quality testing probes 7 to switch positions so that the water quality testing probes 7 can continue to test the water in the testing box 4, reducing waiting time, reducing wasted time, and improving work efficiency. Then, control the water pump to deliver cleaning fluid through the inlet pipe 17 to the cylindrical cylinder 12 so that the nozzle 13 can clean the water quality testing probe 7 that was just tested.

[0030] After the water quality detection probe 7 on the front side completes its detection, the output end of the electric cylinder 21 is extended, causing the water quality detection probe 7 on the front side to move away from the detection box 4. Then, the first motor 20 is controlled to drive the sleeve rod 24 to rotate half a turn through the protruding rod 23. The sleeve rod 24 drives the front and rear sets of water quality detection probes 7 to be swapped through the connecting plate 8. Then, the output end of the electric cylinder 21 is controlled to reset, so that the two sets of water quality detection probes 7 enter the cylindrical cylinder 12 and the detection box 4 respectively.

[0031] The front water quality detection probe 7 extends into the detection box 4 through the through hole 6, the diameter of which is larger than that of the water quality detection probe 7. Meanwhile, in order to reduce cleaning time and improve cleaning effect, the cylindrical cylinder 12 drives the nozzle 13 to rotate, cleaning different parts of the water quality detection probe 7. For this purpose, the cylindrical cylinder 12 is movably sleeved in the horizontal plate 11 through the bearing. During cleaning, the second motor 14 is controlled to drive the gear 15 to rotate, and the gear 15 drives the nozzle 13 to rotate through the ring gear 16, so that the cleaning liquid can be sprayed onto different positions of the water quality detection probe 7, reducing the residue of dirt.

[0032] When the water quality testing probe 7 is performing a test, it transmits the test data to the controller 3 for display.
