The second rotating shaft 15 is connected to the second impeller body 14 in a penetrating manner, and can rotate coaxially with the second impeller body 14. The second impeller body 14 includes a plurality of blades uniformly arranged in a circumferential direction of the second rotating shaft 15, and the number of the blades may be three, for example. The second rotating shaft 15 is coaxially connected with a coded disc 8, and a plurality of through holes 81 are uniformly formed in the coded disc 8 along the circumferential direction. The second impeller body 14 can rotate under the impact of water flow, and drives the code wheel 8 to rotate through the second rotating shaft 15. The sensing module includes a pair of sensing tubes 22. During the rotation of the code wheel 8, the detecting pair tube 22 can be directly opposite to any through hole 81 on the code wheel 8, the faster the water flow speed is, the more the number of the through holes 81 passing through the detecting pair tube 22 in unit time is, that is, the higher the rotation frequency of the second impeller body 14 is, the larger the flow rate value is correspondingly, and the detecting pair tube 22 converts the corresponding rotation frequency into the flow rate value to be displayed on the display screen 3.

When the second impeller body 14 rotates under the impact of water flow, the gear rotates along with the second rotating shaft 15, each tooth of the gear can be just opposite to the detection geminate transistor 22 in the rotating process, the water flow speed is higher, the number of teeth of the geminate transistor 22 in unit time is larger, and the flow value on the display screen 3 is larger.
Referring to fig. 8, an exploded schematic view of the flow monitoring unit provided in the present embodiment is shown. The structure of the outer shell component 5 and the inner shell component 6 is consistent with the embodiment.
Referring to fig. 9, in the present embodiment, the flow monitoring unit also includes an impeller fixing frame, and the impeller assembly 1 is fixed in the mounting cylinder 52 through the impeller fixing frame. But the structure of the impeller fixing frame is different from that of the impeller fixing frame in the first embodiment. Specifically, referring to fig. 8, the impeller mount includes a first semicircular shell 73 and a second semicircular shell 74 which are coupled together. The first and second half- shells 73, 74 define a mounting chamber in which the impeller assembly 1 is disposed and which is open at both ends for the passage of water. One end of the second rotating shaft 15 of the impeller assembly 1 is rotatably connected to the first semicircular shell 73, and the other end penetrates through the second semicircular shell 74 and is fixedly connected with the code wheel 8. Referring to fig. 9, the second rotating shaft 15 is perpendicular to the water flow direction, i.e. perpendicular to the axial direction of the mounting cylinder 52, so that the code wheel 8 can be arranged between the outer wall of the mounting cylinder 52 and the inner wall of the inner housing body 61, and the structure is compact and the layout is reasonable.
