[0041] As described in the background technology, electromagnetic water meters are widely used as water flow measurement equipment. Electromagnetic water meters use the principle of electromagnetic induction to measure water flow and flow rate information. In related technologies, electromagnetic water meters and data terminals are assembled in one piece, or the electromagnetic water meters and data terminals are connected by cables. However, the integrated assembly of electromagnetic water meters and data terminals is less convenient for disassembly and installation, and the connection by cables increases the external interface of the electromagnetic water meter, making the electromagnetic water meter less airtight and prone to leakage.

[0042] In view of the above technical problems, an embodiment of the utility model provides an electromagnetic water meter, which has a split design of a water meter body and a data terminal device, and a connection between the two through a data interaction terminal, and a sealing structure is provided between the water meter body and the data terminal device, so that the data terminal device and the water meter body have both split detachability and few external leakage points. The electromagnetic water meter is more convenient to disassemble and install, and has stronger working stability after assembly.

[0043] In order to make the above-mentioned purposes, features and advantages of the embodiments of the utility model more obvious and easy to understand, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the utility model.

[0044] refer to Figures 1 to 8 The electromagnetic water meter provided by the embodiment of the utility model includes a water meter body 1 and a data terminal device 4. The water meter body 1 has a first data interaction terminal, and the data terminal device 4 has a second data interaction terminal. The first data interaction terminal is electrically connected to the second data interaction terminal. The water meter body 1 is used to monitor and record water flow information, and the data terminal device 4 is used to receive, process and / or store data transmitted by the water meter body 1. A sealing structure is provided between the first data interaction terminal and the second data interaction terminal, which can play a better sealing role between the water meter body 1 and the data terminal device 4.

[0045] In this way, the electromagnetic water meter provided in the present application has fewer external interfaces, reduces the leakage points of the electromagnetic water meter, has better waterproof performance, and has a simple structure while achieving an IP68 waterproof rating.

[0046] In a possible implementation, a socket 2 is provided on the first side of the water meter body 1 to form a first data interaction end. For example, the socket 2 is an aviation socket 2, which has waterproof and dustproof characteristics and can be used outdoors or in harsh environments. The aviation socket 2 is resistant to high temperature and corrosion, and can ensure the normal operation and safe use of the electromagnetic water meter. The data terminal equipment 4 includes a terminal shell, a data terminal module and a power supply device. The terminal shell is fixedly connected to the water meter body 1. For example, the terminal shell is threadedly connected to the water meter body 1 through a threaded connector 9. The threaded connector 9 can be an M5×50 screw 7. The terminal shell has an accommodating cavity. The data terminal module and the power supply device are located in the accommodating cavity. The power supply device is electrically connected to the data terminal module. The terminal shell is provided with a plug 10 to form a second data interaction end. The plug 10 is electrically connected to the data terminal module, and the plug 10 is plugged into the socket 2. For example, a plurality of jacks are arranged at intervals on the socket, and the plug 10 has a plurality of plug terminals. The plug terminals correspond to the jacks one by one.

[0050] In another example, the terminal housing is provided with a connecting block 14, and a mounting hole 15 is provided in the connecting block 14 to accommodate at least a portion of the plug 10. The connecting block 14 provides a layout position for the plug 10 on the data terminal device, and there is no need to open the mounting hole 15 on the terminal housing, which may occupy the volume space of each functional module in the terminal housing.

[0051] In another possible embodiment, the sealing structure includes a sealing ring 3, which is sealingly connected between the mounting seat 13 and the connecting block 14. Furthermore, an annular groove 16 is provided on the connecting block 14, and the annular groove 16 is located at the outer periphery of the mounting hole 15. The sealing ring 3 is embedded in the annular groove 16 of the mounting seat 13, so that the plug 10 is sealed after being plugged into the socket 2, further realizing a sealed connection between the water meter body 1 and the data terminal device 4, so that the structure meets the IP68 level of waterproofing.

[0052] In some embodiments, an adhesive layer 11 is provided between the plug 10 and the mounting hole 15. Exemplarily, the adhesive layer 11 is a glue layer, which can be formed by pouring glue into the wiring where the tail of the plug 10 is connected to the data terminal module, thereby preventing the wires from falling off when the plug 10 is pulled out.

[0053] In other embodiments, a shell is disposed outside the plug 10, a filling cavity is formed between the shell and the plug 10, an adhesive layer is disposed in the filling cavity, a side of the plug 10 facing away from the socket 2 is a wiring terminal, and the wiring terminal of the plug 10 is electrically connected to a circuit board of the data terminal device 4 integrated with a data terminal module through a wire.

[0054] Specifically, when the data terminal device 4 and the water meter body 1 are assembled, the plug 10 is inserted into the socket 2, and the data terminal device 4 is pressed against the sealing ring 3 and pressed onto the water meter body 1, and the plug 10 is retracted into the terminal housing.

[0055] In some other embodiments, the terminal housing is provided with a detection port, and a sealing component is tightly connected to the detection port.

[0056] In a possible implementation, the sealing assembly includes a sealing gasket 5, a washer 6 and a screw 7.

Exemplarily, the sealing gasket 5 is a sealing silicone gasket, the washer 6 is a flat washer 6, and the screw 7 is a hexagonal flat-end fixing screw 7. In this way, the detection port is sealed by the sealing assembly, and the sealing performance is better.

[0057] As a possible implementation, the socket 2 is provided with a detection hole 12, which is located on the first side wall where the socket 2 and the plug 10 are correspondingly plugged in; the water meter body 1 includes a water meter shell and a functional component, the water meter shell has an inner cavity, the functional component is arranged in the inner cavity, and the detection hole 12 is configured to transmit detection gas to the inner cavity, that is, when gas is introduced into the detection port on the terminal shell for leak detection, the gas can flow through the gap at the connection between the plug 10 and the socket 2, and reach the inner cavity of the water meter shell through the detection hole 12, thereby realizing the sealing detection of the head part of the water meter body 1 to ensure the functional stability of the electromagnetic water meter.

[0058] In some embodiments, the water meter housing is provided with a first connection hole, the terminal housing is provided with a second connection hole, and the terminal housing is fixedly connected to the water meter body 1 via a threaded connector 9 penetrating the second connection hole and the first connection hole.
