Utility Model Content

[0003] To address the shortcomings of existing technologies, the purpose of this utility model is to provide an IoT water meter with an easy-to-replace battery, which solves the problem of inconvenient battery replacement in existing IoT water meters after the battery is depleted.

[0004] To achieve the above objectives, this utility model employs the following technical solution:

[0005] An IoT water meter with easy-to-replace batteries includes a water meter body, a control box on the water meter body, a circuit board with network connectivity inside the control box, a battery box detachably installed at the bottom of the control box, and a battery pack that provides power to the circuit board inside the battery box. The battery pack is electrically connected to the circuit board.

[0006] Preferably, the bottom of the control box has a groove for fitting the upper end of the battery box, and a first magnet is embedded in the groove; a second magnet that attracts the first magnet is embedded on the battery box.

[0007] Preferably, an external power interface is provided on the side wall of the control box, and the external power interface is electrically connected to the circuit board.

[0008] Preferably, the side wall of the control box is provided with a sealing buckle for protecting the external power interface.

[0009] Preferably, the external power supply interface is a TYPE-C interface.

[0010] Preferably, a valve is rotatably mounted on the main body of the water meter, and a drive component for opening and closing the valve is installed inside the control box. The drive component is electrically connected to the circuit board.

[0011] Preferably, the valve is a round ball valve.

[0012] Preferably, the driving component is an electric actuator.

[0013] This invention has the following advantages over existing technologies: By detachably mounting the battery pack at the bottom of the control box, it avoids the inconvenience of needing to open the control box with a screwdriver to replace the battery, thus reducing the inconvenience of battery replacement. Furthermore, the battery box and control box are connected magnetically, eliminating the need for tools to remove the battery box and allowing for one-handed operation. In addition, when the IoT water meter battery is depleted and no replacement battery is available, emergency power can be supplied through an external power interface located on the control box.

[0019] The present invention will be further described below with reference to the embodiments, but the scope of protection of the present invention is not limited to the scope described in the embodiments.

[0020] An IoT water meter with easily replaceable batteries, such as Figure 1-5 As shown, the device includes a water meter body 1, a control box 2 on the water meter body 1, a circuit board 3 with network connectivity inside the control box 2, a battery box 4 detachably installed at the bottom of the control box 2, and a battery pack 5 that provides power to the circuit board 3 inside the battery box 4. The battery pack 5 is electrically connected to the circuit board 3.

[0021] In this embodiment, the water meter body 1 is a conventional meter head structure used for measuring water consumption, with an inlet and an outlet. The control box 2 is a plastic box for housing the circuit board 3 and the drive unit 7. The circuit board 3 integrates an emergency valve opening module, a metering module, a communication module, a microcontroller module, a power management module, and a data storage module. The drive unit 7 is a conventional electric actuator in the water meter field, which is a device that converts electrical energy into mechanical energy. It can receive electrical signals from the control system and drive the valve to open or close. It is usually composed of a motor, a transmission device, a position feedback device, etc. The electric actuator can accurately control the valve opening degree and achieve precise regulation of water flow. The battery box 4 is a plastic box, which is installed on the side wall of the control box 2 through a conventional quick-release structure (a snap-fit ​​structure with matching protrusions and slots, a threaded structure with matching bolts and nuts, an interference fit structure, and a door lock structure). This invention removes the need to open the control box 2 with a screwdriver to replace the battery by placing the battery pack 5 in a detachable manner at the bottom of the control box 2, thus reducing the inconvenience of battery replacement.

[0022] Furthermore, the bottom of the control box 2 is provided with a groove 21 for fitting the upper end of the battery box 4, and a first magnet 211 is embedded in the groove 21; a second magnet 41 that attracts the first magnet 211 is embedded on the battery box 4.

[0023] like Figure 4 As shown, the groove 21 is racetrack-shaped, with a first magnet 211 embedded inside. A second magnet 41 is embedded on the battery box 4. When the first magnet 211 and the second magnet 41 approach each other, they attract each other. There is a gap of 0.2-0.5mm between the outer wall of the battery box 4 and the inner wall of the groove. This gap facilitates the insertion of the upper end of the battery box 4 into the groove 21 and also provides good dust and water protection.

[0024] Furthermore, an external power interface (not shown in the attached diagram) is provided on the side wall of the control box 2, and the external power interface is electrically connected to the circuit board 3.

[0025] When the battery of the IoT water meter runs out and there is no replacement battery, emergency power is provided through the external power interface set on the control box 2. The type of external power interface is common Micro-USB, Type-C or dedicated power interface.

[0026] Furthermore, a sealing buckle 22 for protecting the external power interface is provided on the side wall of the control box 2.

[0027] like Figure 3As shown, the sealing buckle 22 is made of soft rubber and is fastened to the side wall of the control box 2 by a conventional fastening structure. On the one hand, it is used to hide the external power interface to improve the aesthetics of the IoT water meter, and on the other hand, it prevents dust and rainwater from contacting the external power interface, thus ensuring the service life of the external power interface.

[0028] Furthermore, to improve the convenience of external power supply, the external power supply interface is set to a TYPE-C interface, which can be used for emergency power supply or to charge battery pack 5 via a power bank, without having to replace battery pack 5.

[0029] Furthermore, a valve 6 is rotatably mounted on the water meter body 1, and a drive component 7 for driving the valve 6 to open and close is provided in the control box 2. The drive component 7 is electrically connected to the circuit board 3.

[0030] like Figure 5 As shown, valve 6 is a sealing and rotating device located at the inlet end of the water meter body 1, and is selected from any one of diaphragm valve, ceramic valve, pilot valve, and ball valve; in order to reduce the blockage caused by impurities adhering around valve 6, valve 6 is preferably a round ball valve.

[0031] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
