[0041] The above solution is adopted: since the bottom of the powder storage tank 38 is open, when the mounting ring 35 is taken out, the powder storage tank 38 needs to be blocked by the baffle plate 39 to prevent powder from spilling out.

[0046] The working principle and use process of the present invention:

[0047] When the device is in use, the opening 3 is opened, and the operator presses the fixing block 37 to compress the spring 51, and removes the mounting ring 35 from the inner wall of the fixing ring 32, and at the same time removes the plug plate 41 from the fixing plate 42, so that the mounting ring 35 and the baffle plate 39 can be taken out of the opening 3, and then the powder storage tank 38 is filled with salt or sodium bicarbonate according to the A liquid dispensing device and the B liquid dispensing device. The powder storage tank 38 is designed to be five annularly distributed on the bottom wall of the mounting ring 35, leaving a position of the powder storage tank 38 uninstalled, and the baffle plate 39 blocks the powder storage tank 38, and then the plug plate 41 is inserted into the fixing plate 42, the fixing block 37 is inserted into the positioning tube 5 to lower the height of the mounting ring 35, and then the square limit block on the top of the mounting ring 35 is inserted into the limit groove 33 to realize the installation of the device, and the first motor 31 is started. The first motor 31 drives the fixing ring 32 and the mounting ring 35 to rotate. When the mounting ring 35 rotates, the powder storage tank 38 passes through the discharge port 310 to realize the delivery of A powder or B powder. After the powder enters the solution, the solution concentration is detected in real time through the conductivity transmitter 9. The upper and lower limits of the prepared solution concentration are pre-set, and 80% of the middle value is taken, and the powder is delivered according to the set value. At this time, the amount of powder added is small, and then a small amount of powder is added to the intermediate value by calculation and setting to achieve the setting of the solution concentration. After the prepared solution is added to the liquid storage tank 6, the second motor 63 is started to work through the touch screen control terminal 10. The outer side of the positioning rod 61 is connected to the mounting plate 71 through the arc plate 7, and is installed on the inner wall of the liquid storage tank 6 in conjunction with the mounting hole 72 on its outer wall. The second motor 63 drives the first connecting rod 65 to rotate. While the first connecting rod 65 rotates, it is meshed and connected with the second gear 68 through the first gear 66. The second gear 68 rotates while driving the second connecting rod 67 rotates synchronously. Since the second connecting rod 67 is fixedly connected to the first mounting rod 69, the third connecting rod 612 is driven by the connection relationship between the first mounting rod 69, the second mounting rod 613 and the connecting ring 614 to realize eccentric circular motion with the center of the second gear 68 as the axis through the connection relationship between the first mounting rod 69 and the second mounting rod 613. The solution is stirred with the stirring block 615. At the same time, the inner gear ring 610 and the connection between the third connecting rod 612 and the second mounting rod 613 are protected by the first protective cover 8 and the second protective cover 81 to prevent the solution from affecting the service life of the structure.
