Description

Technical Field

[0001] The utility model relates to the technical field of flow meters based on 4G signals, in particular to a flow meter based on 4G signals. Background Art

[0002] With the rapid development of science and technology, more and more intelligent water appliances are appearing in people's lives, making them more convenient for people to use. Flow meters are a common component in intelligent water appliances. They can monitor the liquid flow in water appliances in real time and feed back the monitoring signals to the water appliance control center. The control center controls the water appliances according to the monitoring signals to make adjustments and thus realize more intelligent functions.

[0003] A flow meter disclosed in the Chinese utility model patent application disclosure CN220932115U has the advantages of effectively improving the flow meter accuracy and facilitating installation and connection. However, the flow meter still has disadvantages: First, the flow meter only has a metering function, which is relatively simple. In actual use, in some specific cases, in addition to monitoring the flow in the pipeline, it may also be necessary to determine whether there is water in the pipeline. Therefore, it is not convenient and effective to use; Second, there is no filtering mechanism inside the flow meter. In actual use, long-term use may cause the inner wall of the pipeline to be corroded by impurity particles contained in the water, which will affect the service life and may even cause blockage at the connection, affecting the accuracy and precision of the measurement.

The water flows through the limit ring plug 26 and is filtered and processed by the filter screen 25 before entering the interior of the first connecting pipe 4. At this time, the magnetic rotor 13 in the fluid cavity 12 inside the first connecting pipe 4 is impacted by the water flow and rotates, and cooperates with the Hall component 10 on the top to output a pulse signal, which is transmitted to the meter 3 through the external connector 11 for display.
