Description

Technical Field

[0001] This utility model relates to the field of water meter technology, and in particular to a valve-controlled water meter control module and a water meter. Background Technology

[0002] Valve-controlled water meters typically have two operating states: sleep and wake-up. Without manual intervention, the meter usually wakes up automatically once a day to facilitate data communication with the cloud. When valve operation is required in sleep mode, manual pressing of a button is usually necessary to wake the device and control it. However, due to the low frequency of manual wake-up operations over long-term use, the button mechanism is prone to jamming due to prolonged inactivity, thus affecting the meter's subsequent normal operation and functionality. Previously, a quick-release mechanism was typically used at the button mounting point for disassembly and repair in case of button jamming. This not only increased production costs but also resulted in higher labor costs for maintenance. Utility Model Content

[0022] like Figure 1 As shown, the valve-controlled water meter control module provided in this embodiment of the present invention includes: a control box 100, a circuit board 200, a press-activated device 300, and a touch-activated device 400; the circuit board 200 is installed inside the control box 100; the press-activated device 300 is installed on the control box 100, and the touch-activated device 400 is installed on the control box 100 and / or the circuit board 200; the circuit board 200 is provided with sensing parts corresponding to the press-activated device 300 and the touch-activated device 400 respectively.

[0023] The control box 100 is an integral structural component, preferably injection molded from engineering plastics (such as PC or ABS), possessing excellent waterproof and dustproof performance, with a protection rating reaching IP68, suitable for long-term use in outdoor and humid environments. The control box 100 has an internal mounting cavity to accommodate and secure the circuit board 200 and other electronic components. Its outer surface has operating windows or through holes corresponding to the press-activated device 300, allowing external force to be transmitted to the internal triggering structure. The circuit board 200 is installed inside the control box 100, mechanically fixed by screws or clips, and electrically connected to other functional components via solder joints or connectors. The circuit board 200 integrates core components such as a microcontroller (MCU), power management unit, wireless communication module (such as NB-IoT, LoRa, or Bluetooth Low Energy), storage unit, and valve drive circuit. The microcontroller, as the main control chip, is responsible for receiving signal input from the activated device, performing logical judgments, and outputting control commands to drive the water meter's built-in electric valve (such as a solenoid valve or stepper motor valve) to open or close. The press-activated device 300 is mounted on the outer wall of the control box 100, specifically located on the top or side of the control box 100 in a position easily accessible to the user's fingers. The press-activated device 300 can be a tact switch, a silicone button, or a mechanical button. One end of it is exposed outside the control box for the user to press, while the other end extends into the control box and connects to a corresponding pad or socket on the circuit board 200. When the user applies pressure, the press-activated device 300 undergoes physical deformation, triggering the internal switch to close or open, thereby sending a level change signal to the circuit board 200.

[0024] In a preferred embodiment, the press-activated device 300 is a waterproof tactile switch used in conjunction with an elastic silicone cap, which enhances the sealing while ensuring tactile feedback and preventing moisture infiltration that could lead to short circuits.

[0025] The touch excitation device 400 is mounted on the inner surface of the control box 100 or directly integrated onto the circuit board 200. It can also be connected between the control box 100 and the circuit board 200. Specifically, the touch excitation device 400 can be an independent capacitive touch sensor module, attached below the non-metallic area on the front surface of the control box 100; or it can be a sensing pad directly mounted on the circuit board 200, sensing human proximity or contact through a dielectric layer partially permeable to the control box 100. The touch excitation device 400 uses self-capacitance or mutual capacitance detection principles to sense the minute electric field changes generated by a user's finger approaching or lightly touching the surface, converting these changes into electrical signals that are transmitted to dedicated touch detection pins on the circuit board 200 or via I / O. 2 The C interface communicates with the MCU. After receiving the touch signal, the MCU performs software filtering and debouncing to confirm the valid operation event, and then activates the corresponding valve control process.

[0026] In this embodiment of the invention, the touch-activated device 400 includes an induction coil 410, which is installed between the inner wall of the control box 100 and the circuit board 200. The induction coil 410 is shielded inside the control box 100. An operator can approach the induction coil 410 from the outside of the control box 100, thereby causing a corresponding electrical change in the induction capacitor on the circuit board 200. Through program settings for filtering and identification, a wake-up control signal can be generated accordingly when the device is touched.

[0027] In addition, the touch excitation device 400 also includes a first magnet 420; the induction coil 410 is configured as a helical elastic structure, and the first magnet 420 is pressed between the induction coil 410 and the inner wall of the control box 100. If the signal recognition of the induction coil 410 fails under touch operation, a magnet can be applied to the outside of the control box 100 at the position corresponding to the first magnet 420. By bringing the repulsive end of the magnet close to the first magnet 420, a pushing force can be applied to the first magnet 420, thereby compressing the induction coil 410 and further enhancing the electrical signal generated by the touch excitation device 400.

[0028] Furthermore, the touch-activated device 400 also includes a housing 430; a first magnet 420 is embedded in the housing 430, and an induction coil 410 abuts against the housing 430. The housing 430 may be made of insulating material, and the housing 430 is used to wrap and protect the first magnet 420.

[0029] In addition, the housing 430 is slidably fitted to the control box 100 along the axial direction of the induction coil 410. The control box 100 is provided with a sliding groove adapted to the housing 430. The housing 430 is slidably fitted to the sliding groove along the axial direction of the induction coil 410, which can prevent the housing 430 and the first magnet 420 inside it from being misaligned.

[0030] In this embodiment, the press-activated device 300 includes a button 310 and an elastic element 320. The button 310 is slidably connected to the control box 100, and the elastic element 320 is connected between the button 310 and the control box 100. When the user releases the pressure on the button 310, the elastic restoring force of the elastic element 320 drives the button 310 to automatically return to its initial position, thus completing one cycle of triggering operation. Preferably, the elastic element 320 is a helical spring, one end of which abuts against the limiting step or flange of the button 310, and the other end is fixed or abuts against the support structure inside the control box 100. Of course, other forms of elastic elements can also be used, such as rubber pads, elastic buckles, corrugated springs, etc., as long as the elastic reset function can be achieved. The sliding stroke of the button 310 is set to an effective distance sufficient to trigger the internal switching element. In an optional embodiment, the bottom of the button 310 is provided with a trigger portion. When the button is pressed down, the trigger portion pushes an electrical switching element such as a micro switch, conductive rubber contact, or flexible circuit button to actuate, thereby generating an electrical signal and transmitting it to the control circuit. At this time, the elastic element 320 is compressed and stores energy; when the external pressure is removed, the elastic element 320 releases energy, pushing the button 310 to reset, and the switch is turned off or returns to its original state.

[0031] In an optional embodiment, a second magnet 330 is installed inside the button 310. Pressing the button 310 can drive the second magnet 330 to approach the circuit board 200. The electronic components on the circuit board 200 can generate corresponding electrical changes according to the distance of the second magnet 330, so that triggering control can be achieved without the button 310 and the circuit board 200 forming a direct mechanical action.

[0032] Furthermore, the control box 100 includes: a cover 110 and a face shield 120; the cover 110 is provided with a mounting groove 111 adapted to the button 310, and the button 310 and the elastic element 320 are both installed in the mounting groove 111; the face shield 120 is connected to the cover 110, and the face shield 120 is used to prevent the button 310 from being dislodged from the mounting groove 111.

[0033] See Figure 1 and Figure 2 The face mask 120 has a through hole, and the button 310 has a protrusion 311 that fits into the through hole. The protrusion 311 is typically positioned below or flush with the outer end face of the through hole on the face mask 120 to prevent accidental activation of the button 310. When the button 310 needs to be pressed, a thin rod-like tool can be used to push against the protrusion 311 to operate the button 310.

[0034] like Figure 1 and Figure 2 As shown, the water meter provided in this embodiment of the present invention is equipped with the valve-controlled water meter control module described in the above embodiments. This water meter has the same technical advantages as the valve-controlled water meter control module described above, which will not be repeated here.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
