Description

Technical Field

[0001] This utility model relates to the field of multifunctional water meter technology, specifically a multifunctional water meter with NFC detection function. Background Technology

[0002] A water meter is an instrument used to measure water flow, mostly measuring the cumulative flow. It is generally divided into two categories: volumetric water meters and velocity water meters. Originating in England, water meters have a history of nearly two hundred years and are indispensable in modern life. However, existing water meters still have some shortcomings, such as:

[0003] The water meter described in application number CN201010510462.X does not have an online billing function and uses traditional mechanical and electronic display technology for display. As a result, the device still requires manual recording of flow rate and billing, which is not only time-consuming and labor-intensive, but also inconvenient for multiple users to use simultaneously. Utility Model Content

[0004] The purpose of this utility model is to provide a multi-functional water meter with NFC detection function, in order to solve the problem mentioned in the background art that the existing devices on the market do not have online billing function and use traditional mechanical and electronic display technology as the display, which means that the devices still need to manually record the flow rate and write the bill, which is not only time-consuming and labor-intensive, but also inconvenient for multiple users to use at the same time.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-functional water meter with NFC detection function, comprising a first interface, an ultrasonic host, a buffer tube, a check valve, and a water passage hole;

[0006] An ultrasonic generator, a buffer tube, and a check valve are provided on the right side of the first interface. The buffer tube contains a first guide channel, a second guide channel, a first magnetic block, a buffer block, and a second magnetic block. An adjusting bolt is installed above the buffer tube. The check valve contains a spring, a guide valve, and a stop valve. A second interface is provided on the right side of the check valve.

[0007] As a preferred technical solution of this utility model, an ultrasonic host is provided on the right side of the first interface, and four sensors are evenly fixed below the ultrasonic host and placed inside the pipe of the first interface. The ultrasonic host has NFC detection and wireless function and uses a TFT LCD instrument display. The first interface is a flange structure, and eight bolt holes are evenly opened on the side of the first interface.

[0008] By adopting the above technical solution, the device can ensure its sealing and compatibility through a mature connection structure by setting the first interface as a flange structure. The four sensors evenly fixed below the ultrasonic host and placed inside the pipe of the first interface can effectively improve the accuracy of the device's flow monitoring. The NFC detection and wireless functions can ensure the device's functionality and adaptability to various scenarios.

[0009] As a preferred technical solution of this utility model, a buffer tube is fixedly connected to the right side of the first interface, and an elbow pipe is provided between the buffer tube and the first interface. A buffer block is slidably connected inside the buffer tube. The buffer block is made of plastic, and six water passage holes are evenly opened on the outer ring of the buffer block. Magnets are fixedly connected to both ends of the water passage holes.

[0010] By adopting the above technical solution, the device can reduce the impact of water flow and slow down the flow rate by setting an elbow pipe between the buffer pipe and the first interface. The buffer block is made of plastic and has six water passage holes evenly opened on the outer ring of the buffer block, which can ensure durability while allowing water to flow normally.

[0011] As a preferred technical solution of this utility model, a second magnetic block is fixedly connected inside the pipe on the left side of the buffer block, and a first magnetic block is fixedly connected inside the pipe on the right side of the buffer block. The magnetic poles of the first magnetic block and the second magnetic block are the same as the magnetic poles of the contact surface of the buffer block. Adjusting bolts are threadedly connected to both sides of the buffer tube. A cross groove is opened on the upper surface of the adjusting bolt, and a first guide groove and a second guide groove are opened below the adjusting bolt. The first guide groove and the second guide groove form a 60-degree angle structure.

[0012] By adopting the above technical solution, the device sets the magnetic poles of the first magnetic block and the second magnetic block to be the same as the magnetic poles of the contact surface of the buffer block. It can use the principle of like poles repulsion to move the buffer block within the buffer tube, thereby achieving a good water flow buffering effect. The first guide channel and the second guide channel are at a 60-degree angle.

[0013] As a preferred technical solution of this utility model, a check valve is fixedly connected to the right side of the buffer pipe, and a bend pipe is fixed between the check valve and the buffer pipe. A guide valve is fixedly connected inside the check valve. The guide valve has a trumpet-shaped structure, and a water stop plug is slidably connected to the center position inside the guide valve. A spring is fitted on the right side of the water stop plug. A second interface is fixedly connected to the right side of the check valve. The second interface has the same structure as the first interface.

[0014] By adopting the above technical solution, the device can further slow down the water flow inside the pipe by fixing an elbow pipe between the check valve and the buffer pipe. The guide valve has a funnel-shaped structure, which can separate the water flowing through the stop valve under the push of the spring and complete the water flow compression in the pipe, thereby increasing the flow rate when the water is discharged.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. By setting the first interface as a flange structure, the device can ensure its sealing and compatibility through a mature connection structure. The four sensors evenly fixed below the ultrasonic host and placed inside the pipe of the first interface can effectively improve the accuracy of the device's flow monitoring. The NFC detection and wireless functions can ensure the device's functionality and adaptability to various scenarios, and meet the needs of rapid billing switching for multiple users.

[0017] 2. This device reduces the impact of water flow and slows down the flow rate by setting an elbow pipe between the buffer pipe and the first interface. The buffer block is made of plastic and has six water passage holes evenly opened on the outer ring of the buffer block, which can ensure durability while allowing water to flow normally.

[0018] 3. By setting the magnetic poles of the first magnetic block and the second magnetic block to be the same as the magnetic poles of the contact surface of the buffer block, the device can use the principle of like poles repulsion to move the buffer block within the buffer tube, thereby achieving a good water flow buffering effect. The first guide channel and the second guide channel are at a 60-degree angle.

[0019] 4. This device can further slow down the water flow inside the pipe by fixing an elbow pipe between the check valve and the buffer pipe. The guide valve has a funnel-shaped structure, which can separate the water flowing through the stop valve under the push of the spring and complete the water flow compression in the pipe, thereby increasing the flow rate when the water is discharged.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1 - Figure 6 The present invention provides a multi-functional water meter with NFC detection function, comprising a first interface 1, an ultrasonic host 2, a buffer tube 3, a check valve 4, a second interface 5, an adjusting bolt 6, a first guide groove 7, a second guide groove 8, a spring 9, a guide valve 10, a water stop 11, a first magnetic block 12, a buffer block 13, a second magnetic block 14, and a water passage hole 15.

[0029] The ultrasonic main unit 2, buffer pipe 3, and check valve 4 are located on the right side of the first interface 1. Four sensors are evenly fixed below the ultrasonic main unit 2 and placed inside the pipe of the first interface 1. The ultrasonic main unit 2 has NFC detection and wireless functions and uses a TFT LCD display. The first interface 1 has a flange structure, and eight bolt holes are evenly distributed on its side. By using a flange structure for the first interface 1, the device can ensure its sealing and compatibility through a mature connection structure. The evenly fixed four sensors below the ultrasonic main unit 2 and placed inside the pipe of the first interface 1 can effectively improve the accuracy of flow monitoring. The NFC detection and wireless functions ensure the device's... To ensure functionality and adaptability, the buffer tube 3 is equipped with a first guide channel 7, a second guide channel 8, a first magnetic block 12, a buffer block 13, and a second magnetic block 14. The buffer tube 3 is fixedly connected to the right side of the first interface 1, and an elbow pipe is provided between the buffer tube 3 and the first interface 1. The buffer block 13 is slidably connected inside the buffer tube 3. The buffer block 13 is made of plastic, and six water passage holes 15 are evenly distributed on its outer ring. Magnets are fixedly connected to both ends of each water passage hole 15. By providing an elbow pipe between the buffer tube 3 and the first interface 1, this device can reduce the impact of water flow and slow down the flow rate. The fact that the buffer block 13 is made of plastic and has six water passage holes 15 evenly distributed on its outer ring ensures durability while allowing normal water flow. An adjusting bolt 6 is installed above buffer block 13. A second magnetic block 14 is fixedly connected inside the pipe on the left side of buffer block 13, and a first magnetic block 12 is fixedly connected inside the pipe on the right side of buffer block 13. The magnetic poles of the first magnetic block 12 and the second magnetic block 14 are the same as the magnetic poles of the contact surface of buffer block 13. The adjusting bolt 6 is threaded to both sides of buffer pipe 3. A cross groove is opened on the upper surface of the adjusting bolt 6, and a first guide groove 7 and a second guide groove 8 are opened below the adjusting bolt 6. The first guide groove 7 and the second guide groove 8 form a 60-degree angle structure. By setting the magnetic poles of the first magnetic block 12 and the second magnetic block 14 to be the same as the magnetic poles of the contact surface of buffer block 13, this device can move buffer block 13 within the buffer pipe 3 using the principle of like poles repulsion, thus achieving good water flow. The device provides a buffering effect, with the first guide channel 7 and the second guide channel 8 forming a 60-degree angle. The check valve 4 contains a spring 9, a guide valve 10, and a stop valve 11. A second interface 5 is located on the right side of the check valve 4. The right side of the buffer pipe 3 is fixedly connected to the check valve 4. A bend in the pipe is fixed between the check valve 4 and the buffer pipe 3. The guide valve 10 is fixedly connected inside the check valve 4, and the guide valve 10 has a trumpet-shaped structure. The stop valve 11 is slidably connected to the center of the guide valve 10. The spring 9 is fitted on the right side of the stop valve 11. The right side of the check valve 4 is fixedly connected to the second interface 5, which has the same structure as the first interface 1. This device, by fixing a bend in the pipe between the check valve 4 and the buffer pipe 3, can further slow down the water flow inside the pipe. The guide valve 10 has a trumpet-shaped structure.The spring 9 can push the water flowing through the stop valve 11 to separate the water flow and compress it within the pipe, thus increasing the flow rate at the outlet.

[0030] Working principle: When using a multi-functional water meter with NFC detection function, the device is first installed in a suitable position on the water supply pipeline through the first interface 1 and the second interface 5. When water flows through, the sensor of the ultrasonic host 2 records the water flow data in real time and synchronizes it to the cloud wirelessly. The NFC detection function can be connected to the valve to realize functions such as quick payment. When the valve is closed, the reaction force generated by the water flow will first enter the buffer pipe 3, causing the buffer block 13 to shift and dissipate the impact force. After the water pressure is lost in the check valve 4, the spring 9 will push the stop plug 11 outward, automatically closing the check valve 4, stopping the backflow, and the water in the buffer pipe 3 will be retained, while preventing water flow fluctuations and ensuring the accuracy of the ultrasonic host 2 sensor.

[0031] This completes a series of tasks. The contents not described in detail in this specification are existing technologies known to those skilled in the art.
