Description

Technical Field

[0001] This utility model relates to the field of drinking water testing technology, and in particular to a mixing device for drinking water testing. Background Technology

[0002] Mixing refers to homogenization. In the process of testing drinking water, in order to prevent various substances in the drinking water from settling to the bottom and becoming undetectable by the detection probe, it is generally necessary to first mix the drinking water in the test cup to ensure that the various substances in the drinking water are evenly distributed in the test cup, so that the detection probe can detect them.

[0003] Current mixing devices typically perform the mixing of liquids in a test cup individually, using a single-tank structure. After the test cup is placed in the single tank, the mixing device is turned on, and the stirring mechanism inside the device moves from top to bottom to insert into the test cup and complete the mixing process. This single-tank structure means that the mixing operation can only be completed for one test cup at a time, which can easily lead to a slow testing speed for drinking water. Utility Model Content

A transverse bevel gear 15 is fixedly connected to the top end of the connecting shaft 14, and a circular disk 16 is fixedly connected to the bottom end of the connecting shaft 14. Several stirring arms 17 are fixedly connected to the lower surface of the circular disk 16.

[0021] Both first vertical bevel gears 11 mesh with transmission bevel gears 7, and both second vertical bevel gears 12 mesh with two horizontal bevel gears 15 respectively. The left and right sides of the movable frame 4 are provided with through holes that match the support frame 8. The lower surface of the support frame 8 is provided with rectangular holes that match the rectangular frame 13. The servo motor 5 is electrically connected to the controller 2, and the position of the circular disk 16 corresponds to the position of the circular groove. The surface of the connecting shaft 14 is fitted with a rubber top cover 18. After the servo motor 5 is turned on by the controller 2, the servo motor 5 can drive the transmission bevel gear 7 to rotate through the rotating shaft 6, thereby driving the two circular rods 10 to rotate through the two first vertical bevel gears 11. The two circular rods 10 then drive the horizontal bevel gears 15 and the connecting shaft 14 to rotate through the two second vertical bevel gears 12. The connecting shaft 14 can drive the circular disk 16 and the stirring arm 17 to perform a mixing operation on the liquid in the test cup.

At this time, the support frame 8 and the rectangular frame 13 can lift the circular disk 16 and the stirring arm 17. When the stirring arm 17 rises above the height of the test cup, place the two test cups that need to be mixed into the two circular slots. Then, rotate the threaded rod 20 counterclockwise, causing the strip plate 21 and the bottom support plate 22 to lower the movable frame 4. The circular disk 16 can then lift the stirring arm 17 into the test cup. At the same time, the rubber top cover 18 can cover the top of the test cup to ensure that the liquid does not splash during the mixing process. At this time, the control is used to... When device 2 turns on servo motor 5, servo motor 5 drives rotating shaft 6 to rotate. Rotating shaft 6 drives transmission bevel gear 7 at the top to rotate. Transmission bevel gear 7 drives two circular rods 10 to rotate through two first vertical bevel gears 11.
