Problems solved by technology
[0002] At present, the water meter is mainly composed of the water meter base and the counter part. The counter part includes the magnetic transmission component. Because it is magnetic, it is easily disturbed by the external magnetic field and the reading is inaccurate.
In addition to external interference, its own magnetic transmission components will also affect the readings of the water meter

The invention discloses a counting mechanism and a water meter comprising the same. The counting mechanism comprises an upper clamping plate, a lower clamping plate, a pointer arranged inside the upper clamping plate and a movement gear set located between the upper clamping plate and the lower clamping plate, the movement gear set comprises a central gear in transmission connection with an impeller, a first counting gear set in transmission connection with the central gear and a second counting gear set which is in transmission connection with the central gear and is used for induction reading; a reading pointer is in transmission connection with the second counting gear set. By applying the water meter comprising the counting mechanism, the water meter can be effectively prevented from being disturbed by the external world and a magnetic field, on the basis of not affecting original water meter reading, the electronic reading function is added, and the water meter measuring accuracyis improved.
Description
technical field [0001] The invention relates to a water meter, in particular to a technical mechanism used in the water meter and a water meter containing the counting mechanism. Background technique [0002] At present, the water meter is mainly composed of a water meter base and a counter part. The counter part includes a magnetic transmission component. Because it is magnetic, it is easily disturbed by an external magnetic field and the reading is inaccurate. In addition to external interference, the magnetic transmission components themselves will also affect the readings of the water meter. Contents of the invention [0003] Purpose of the invention: In order to overcome the above problems, the present invention provides a counting mechanism, which can effectively prevent the water meter from being disturbed by the external magnetic field, increase the electronic reading function without affecting the original water meter reading, and improve the accuracy of water met...
