Compared with traditional water meters that generally only have the functions of flow collection and mechanical pointer display of water consumption, it is a great improvement.

[0003] Smart water meters are usually equipped with various functional modules, such as camera modules, etc., to monitor the water volume of the water meter in real time, thereby realizing the automatic data collection function of the smart water meter. Among them, the main structure of the shell of these functional modules is usually composed of a base body and a cover plate. The cover plate is arranged on the base body and surrounds a sealed cavity. The sealing ring is used to install and store the control board. The side of the base body is provided with a wire hole connected to the sealed cavity. The wire passes through the wire hole into the sealed cavity and is electrically connected to the control board.

[0004] In order to ensure the waterproof performance of the housing, the wire hole on the side wall of the housing needs to be sealed; currently, this is mainly done by installing a sealing plug in the wire hole, and providing a wiring hole for the wire to pass through on the sealing plug. However, since water with a certain pressure can impact the sealing plug, the sealing effect between the sealing plug and the wire hole is poor, and it is easy for water to enter the housing through the gap between the sealing plug and the wire hole, thereby affecting the performance of the control board. Therefore, it is necessary to improve the current housing. Utility Model Content
