One end of the spring wire is connected to the magnetic column, and the other end of the spring wire is connected with the water flow measuring plate, and the impeller box is A positioning column is provided, and a middle portion of the spring wire is rotatably mounted on the positioning column. The magnetic position sensing component is installed above the water blocking plate, and the magnetic position sensing component is connected with the MCU processing circuit. The magnetic position sensing component is a first Hall sensor or a reed switch. The head part includes a stepping motor sensor, a second Hall sensor, a stepping motor sensor, and a second Hall sensor installed on both sides of the magnetic steel. The stepper motor sensor includes a magnetic stator stator and a magnetic conductive stator. A chip-connected core, a package-connecting wiring board component for inducing a magnetic field change and generating a voltage signal, and a second Hall sensor including a measuring Hall component, a wire package terminal board component, and a measurement Hall component are respectively connected to the MCU processing circuit.

Line pack terminal block components are also connected to a super capacitor. A protective cover is provided at the top of the head part, and a magnetic shield is provided above the stepper motor sensor and the second Hall sensor. There is a communication part next to the head part. The communication part includes an antenna seat, an antenna, an antenna protection cover and a communication battery. The antenna is arranged on the antenna seat, the antenna protection cover is wrapped on the outside of the antenna, and the communication battery is installed under the antenna seat. The antenna is connected to the communication module of the MCU processing circuit. The rear end of the impeller is provided with a slot, and the head of the silicone blade is provided with an insert block adapted to the shape of the slot, and the insert block is inserted into the slot and tightly connected thereto. The trailing end of the silicone blade is arranged to facilitate the diversion of the flow.

The beneficial effects of the present invention are as follows: 1. The present invention has a soft material silicone blade at the end of each impeller, so that the sand in the water that cannot be blocked after filtering by the filter can also smoothly pass through the soft material of the silicone blade and can be solved. Kasha problem. 2. The present invention is provided with a water flow measuring piece, a spring wire, a magnetic column, and a magnetic position sensing component, so that the water flow measuring piece drives the movement of the magnetic column, the magnetic position sensing component senses the magnetic field change of the magnetic column, and the magnetic position sensing component converts the magnetic field change into The electrical pulse signal is sent to the MCU processing circuit to know the flow status and send the water meter status to the cloud platform. When there is filiform or strip foreign matter entering and winding the impeller is not moving, the water platform fault information is sent to the cloud platform, and the intelligent cloud platform promptly reminds the staff to repair and maintain. 3. The stepping motor sensor and Hall sensor installed on both sides of the magnetic steel synchronously obtain the synchronous rotation state and signal of the impeller, and the magnetic stator is transferred to the iron core all the way, and the magnetic field is generated due to the rotation of the magnetic steel. The magnetic field lines are cut, voltage signals are induced on the wiring board components, and are input to the MCU processing circuit through the wires; the other circuit generates electrical pulse signals on the measuring Hall components and is synchronously input to the MCU processing circuit via the wires.
