[0030] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0031] Please also read Figures 1 to 4 , the ultrasonic flowmeter with water leakage detection function provided by the utility model is now described. The ultrasonic flowmeter with water leakage detection function includes a main body 10, an ultrasonic structural member 20, a power line 30, a water immersion sensing assembly 40 and a fixing assembly 50. The main body 10 includes an ultrasonic module 11 and a water leakage detection module 12; the ultrasonic structural member 20 is arranged on the side of the main body 10 facing the water pipe, the ultrasonic structural member 20 includes a transmitter 21 and a receiver 22, and the ultrasonic structural member 20 is communicatively connected with the ultrasonic module 11; the power line 30 is connected to the main body 10 and used to power the main body 10; the water immersion sensing assembly 40 is electrically connected to the power line 30, and the water immersion sensing assembly 40 includes a sensing head 41; the fixing assembly 50 is connected to the main body 10, and the fixing assembly 50 is used to fix the main body 10 to the outer periphery of the water pipe.

[0032] Compared with the prior art, the ultrasonic flowmeter with water leakage detection function provided in this embodiment is installed on the outer periphery of the water pipe through the fixing component 50, and the induction head 41 on the water immersion sensing component 40 is placed at the place where the water leakage needs to be detected. During operation, the ultrasonic structure 20 measures the flow rate of the liquid in the water pipe by transmitting and receiving ultrasonic waves, thereby calculating the flow rate; the water immersion sensing component 40 can directly obtain whether there is a water leakage at the position to be detected through the induction head 41. The ultrasonic flowmeter with water leakage detection function of the utility model can detect whether there is a water leakage through the water immersion sensing component 40, and can also detect the water flow through the ultrasonic structure 20, so as to achieve more comprehensive monitoring of the water use in the home, and facilitate users to take corresponding measures in time when there is a water leakage or abnormal water consumption; the fixing component 50 can facilitate the loading and unloading of the main body 10, which is convenient for users to operate and reduces the difficulty of use.

[0033] In some embodiments, a specific implementation of the main body 10 can be as follows: Figure 1 and Figure 3 See the structure shown. Figure 1 and Figure 3 The main body 10 is provided with a display screen 13 and a button 14 on the outside. The display screen 13 on the outside of the main body 10 is connected to the ultrasonic module 11 and the water leakage detection module 12, so that the measured water consumption and the signal of whether there is a water leakage can be directly displayed on the display screen 13, which is convenient for the user to observe the real-time water consumption, and the button 14 can be used for zeroing, adjusting the brightness, etc., which is convenient to use.

[0034] Optionally, the display screen 13 may be an LED display screen 13 or a touch screen, etc.; the button 14 may be made of silicone material, which has a softer touch.

[0035] In some embodiments, an improved implementation of the main body 10 can be as follows: Figures 1 to 3 See the structure shown. Figures 1 to 3 The main body 10 is provided with a protrusion 15 on one side facing the water pipe, and the protrusion 15 has a through hole 16, and the fixing component 50 is a throat clamp passing through the through hole 16. The throat clamp passes through the through hole 16 on the main body 10 and is sleeved on the outer periphery of the water pipe, and then the throat clamp is locked to complete the fixing of the main body 10 on the water pipe. The fixing structure has low cost, is easy to use, and has low operation difficulty.

[0036] In order to improve the stability of the fixing of the main body 10, protrusions 15 and throat clamps are provided on opposite sides of the main body 10 along the axial direction of the water pipe.

[0037] In some embodiments, an improved implementation of the protrusion 15 can be as follows: Figures 1 to 3 See the structure shown. Figures 1 to 3The protruding portion 15 has a slot 17 that fits the water pipe, and the width of the slot 17 gradually decreases in the direction away from the water pipe. The slot 17 opens toward the water pipe, so when the throat clamp is fixed, the slot 17 fits the outer surface of the water pipe, and the side wall of the slot 17 and the part of the throat clamp extending out of the hole 16 are surrounded by the outer periphery of the water pipe, thereby fixing the main body 10; the width of the slot 17 gradually decreases in the direction away from the water pipe, which can adapt to the installation of water pipes of various diameters and has a wide range of applications.

[0038] It should be noted that the through hole 16 and the clamping groove 17 are located at the same position in the axial direction of the water pipe, so as to ensure that the clamping groove 17 and the throat clamp cooperate to fix the main body 10 .

[0039] In some embodiments, an improved implementation of the main body 10 can be as follows: Figure 2 See the structure shown. Figure 2 The main body 10 is provided with a mounting frame 18 on the side facing the water pipe. The mounting frame 18 has two mounting grooves 19. The transmitter 21 and the receiver 22 are respectively snapped into the two mounting grooves 19. The ultrasonic module 11 has a connector extending into the two mounting grooves 19. Before installation, the transmitter 21 is first connected to the connector and then snapped into the corresponding mounting groove 19. The installation process of the receiver 22 is similar. This structure facilitates the installation and replacement of the transmitter 21 and the receiver 22.

[0040] In order to facilitate disassembly, a side wall of the installation groove 19 is recessed in a direction away from the water pipe to form a quick release opening 110, and the quick release opening 110 passes through the side wall of the installation groove 19. In actual use, the height of the transmitter 21 is greater than or equal to the corresponding depth of the installation groove 19, and the height of the receiver 22 is greater than or equal to the corresponding height of the installation groove 19. By setting the quick release opening 110, when it is necessary to disassemble the transmitter 21 or the receiver 22, tools or hands can be used to contact the side wall of the transmitter 21 or the receiver 22 from the position of the quick release opening 110, and then pull it out.

[0041] In some embodiments, an improved implementation of the power cord 30 may be as follows: Figure 1 See the structure shown. Figure 1 A branch interface 31 is provided in the middle of the power cord 30, and the water immersion sensor assembly 40 further includes a plug 42 connected to the sensor head 41, and the plug 42 is plugged into the branch interface 31. By plugging the plug 42 into the branch socket, the water immersion sensor assembly 40 can be easily disassembled and replaced, and the water immersion sensor assembly 40 can be disassembled and stored separately when it is not needed.

[0042] Specifically, the induction head 41 includes a conductor 43 and two conductive coils 44 sleeved on the conductor 43, and the two conductive coils 44 are spaced apart. Under normal circumstances, the two-pole probes of the induction head 41 (i.e., the two ends of the two conductive coils 44) are insulated by air; the induction head 41 is placed at a location that needs to be detected. When water leakage occurs at this location, because water conducts electricity, water contacts the induction head 41, which causes current to be detected in the main body 10, thereby determining that water leakage has occurred at this location.

[0043] As a modified implementation, the sensing head 41 may also be a thermal imaging detection head, an ultrasonic detection head, etc.

[0044] In some embodiments, an improved implementation of the main body 10 can be as follows: Figure 3 to Figure 4 See the structure shown. Figure 3 to Figure 4 The main body 10 also includes a wireless transmission module 111. The wireless transmission signal can receive the signals sent by the ultrasonic module 11 and the water leakage detection module 12, and transmit the water consumption and water leakage information to a remote device (such as a mobile phone, tablet, etc.), so that the user can remotely observe the water consumption at home.

[0045] Specifically, a circuit board 112 is provided in the main body 10, and the ultrasonic module 11, the water leakage detection module 12 and the wireless transmission module 111 are all integrated in the circuit board 112. Integrating multiple modules on a circuit board 112 can reduce space occupation, thereby reducing the volume of the main body 10, making the whole more compact and easy to carry.

[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
