Technical Field

[0001] The utility model relates to the field of water meters, in particular to a sealing interface of an IC card prepaid water meter. Background Art

[0002] A water meter is an instrument that measures water flow, most of which measure the cumulative flow of water. It is generally divided into two categories: volumetric water meters and velocity water meters. It originated in the UK and has a history of nearly two hundred years. When selecting the specifications of a water meter, you should first estimate the size and flow range of the flow rate used under normal circumstances, and then choose a water meter with a commonly used flow rate closest to this value as the first choice.

[0003] At present, water meters play a very important role in recording water consumption. Current water meters are gradually being replaced by IC cards. Existing IC cards are basically directly inserted into the inside of a sealed interface for use and consumption. However, since they are directly inserted, they are prone to loosening and poor contact after repeated insertion and removal. If the IC card is loose, it is easy to damage not only the IC card but also the connector of the water meter, greatly reducing the safety of the water meter. Therefore, those skilled in the art provide a sealed interface for an IC card prepaid water meter to solve the problems raised in the above background technology. Utility Model Content
