[0027] The water supply detection devices in the prior art usually can only achieve the basic flow monitoring function and lack the ability to detect other parameters of the water quality, resulting in many problems in the water supply system that cannot be discovered and solved in time.

[0028] Refer to Figures 1 to 5 , the present invention provides a multifunctional water supply terminal, including:

[0029] The ultrasonic pipe segment detection component 100 comprises an ultrasonic pipe segment 101, wherein a group of ultrasonic transducer mounting holes, a temperature sensor mounting hole and a pressure sensor mounting hole are arranged on the top of the ultrasonic pipe segment 101, wherein a corresponding ultrasonic transducer component 102 is completely embedded in each of the group of ultrasonic transducer mounting holes, a temperature sensor 103 for detecting the water flow temperature is completely embedded in the temperature sensor mounting hole, a pressure sensor 104 for detecting the water flow pressure is completely embedded in the pressure sensor mounting hole, the temperature sensor 103 and the pressure sensor 104 are signal-connected to a sensor circuit board 105a, the ultrasonic transducer component 102 is signal-connected to an adapter board 105b, and the adapter board 105b is signal-connected to a circuit main board 105c;

A detection tube 204 is inserted into the ball valve 203c. A group of detection tubes 204 are respectively inserted with a residual chlorine detector 205 in the residual chlorine detection component 201 and a pH value detector 206 in the pH value detection component 202. The detection ends of the residual chlorine detector 205 and the pH value detector 206 are inserted into the ball valve pipe section 203a to contact the water flow. The detection tube 204 and the ball valve vertical pipe 203b are screwed together. The residual chlorine detector 205 and the pH value detector 206 are screwed together with the corresponding detection tubes 204. The pH value detector 206 and the residual chlorine detector 205 are both connected to the sensor circuit board 105a for signal connection;

[0031] The signal display screen 300 is signal-connected to the circuit main board 105c and the sensor circuit board 105a;

[0032] The sealing cover 400 includes an upper cover 401, a motor plastic cover 402 and a bottom cover 403. The bottom cover 403 is provided with a battery for supplying power to all components.

[0033] It should be noted that the temperature sensor 103, the pressure sensor 104, the residual chlorine detector 205 and the pH value detector 206 all adopt existing conventional sensors, which will not be described in detail here.

[0034] It should be noted that the ultrasonic transducer assembly 102 measures corresponding parameters through the existing ultrasonic signal measurement principle.

[0035] It should be noted that in the present invention, the temperature parameter is detected by a temperature detector; the pressure parameter is detected by a pressure detector; the residual chlorine parameter is detected by a residual chlorine detector; the pH value parameter is detected by a pH value detector; the instantaneous flow rate parameter is detected by an ultrasonic transducer; and the cumulative flow rate parameter is detected by an ultrasonic transducer.

[0036] Specifically:

[0037] From the two parameters of "instantaneous flow rate" and "cumulative flow rate", in this solution, the ultrasonic transducer assembly in the overall ultrasonic measurement structure is used for measurement. From the perspective of the detection device itself, two functions of ultrasonic detection and valve control can be realized;

[0038] From the two parameters of "temperature" and "pressure", in this solution, the temperature sensor 103 and the pressure sensor 104 in the overall ultrasonic measurement structure are used for measurement;

[0039] From the two parameters of "residual chlorine parameter" and "pH value parameter", in this solution, the residual chlorine detection component 201 and the pH value detection component 202 are used for measurement. The relevant sensors are installed in the rear-end structure, and the configured switching valve prevents water spraying when replacing the sensors.

[0040] Specifically, filter meshes are provided at both the water inlet and the water outlet of the ultrasonic pipe section 101;

[0041] Among them, a mesh filter mesh is provided at the water inlet, and a cross-shaped filter mesh is provided at the water outlet;

[0042] Among them, a mesh filter mesh is provided at the other end of the ball valve pipe section 203a.

[0043] The filter mesh is used for preliminary filtration of the water quality.

[0044] Specifically, the pressure sensor 104 is screwed into the pressure sensor mounting hole through a pipe section transfer nut, and a sealing O-ring is also provided at the connection between the transfer nut and the pressure sensor mounting hole.

[0045] Specifically, the temperature sensor 103 is inserted into the temperature sensor mounting hole through a small sleeve, and a sealing O-ring is also provided at the connection between the small sleeve and the temperature sensor mounting hole.

[0046] Specifically, the ultrasonic transducer assembly 102 specifically includes a housing 102a, in which a ceramic wafer 102b is arranged. A rubber pad 102c is disposed on the ceramic wafer 102b. A joint member 102d joints with the housing 102a to realize the closed accommodation of the ceramic wafer 102b and the rubber pad 102c. A cap nut is further covered on the housing 102a. A sealing O-ring is also arranged at the joint of the cap nut and the ultrasonic transducer mounting hole. A sealing O-ring is also arranged at the joint of the housing 102a and the ultrasonic transducer mounting hole.

[0047] It should also be noted that, in order to install the ultrasonic transducer assembly 102 and the pressure sensor 104 more firmly and make the overall ultrasonic detection structure more complete, generally a pipe section cover plate will be installed after the series of sensors are installed into the top mounting holes of the corresponding ultrasonic pipe section 101. As shown in the attached drawings, it can also not be installed, which will not affect the realization of the overall function.

[0048] Specifically, a sealing O-ring is arranged at the screw connection between the detection pipe 204 and the ball valve vertical pipe 203b.

[0049] Specifically, polytetrafluoroethylene rings are arranged at both the upper and lower ends of the ball valve 203c, and a sealing O-ring is also synchronously arranged at the joint of its bottom and the ball valve pipe section 203a.

[0050] Specifically, a steel sleeve retaining ring 207 is also screwed at the bottom of the detection pipe 204, and the diameter of the steel sleeve retaining ring 207 is larger than the top diameter of the ball valve vertical pipe 203b.

[0051] Specifically, a sealing O-ring is also arranged at the screw connection between the steel sleeve retaining ring 207 and the detection pipe 204.

[0052] Preferably, in order to stably install the ball valve vertical pipe 203b into the ball valve pipe section 203a, in addition to a set of screw fittings, generally a valve joint is also designed at the bottom of the ball valve vertical pipe 203b, as shown in the figure. However, the non-installation of this structure will not affect the realization of the overall structure.

[0053] During the use process, when water is passed through and measurement is started, the residual chlorine detection component 201, the pH value detection component 202, the temperature sensor 103, and the pressure sensor 104 respectively transmit the detected parameters to the signal display screen 300 for display.

[0054] Especially when it is necessary to replace the residual chlorine detector 205 and the pH value detector 206: keep the water flowing, unscrew the detection pipe 204 from the ball valve vertical pipe 203b and lift it upward. During this process, the steel sleeve retaining ring 207 will block the gushing water flow. After lifting to a certain extent, turn the ball valve 203c to close the upward water flow, and then unscrew the detector from the corresponding detection pipe to realize the replacement. During this process, the ingenious structural design prevents the water spray phenomenon from occurring when replacing the sensor.

[0055] The present invention provides a multifunctional water supply terminal. An ultrasonic transducer assembly in the overall structure is used for dual-parameter measurement of instantaneous flow rate and cumulative flow rate. From the perspective of the detection device itself, two functions of ultrasonic detection and valve control can be realized. A temperature sensor and a pressure sensor in the overall structure using ultrasonic measurement are used for dual-parameter measurement of temperature and pressure. A residual chlorine detection component and a pH value detection component are used for dual-parameter measurement of residual chlorine parameters and pH value parameters. At the same time, the relevant sensors are installed in the rear-end structure, and the configured on-off valve also prevents water spraying during sensor replacement, solving the problem that existing water supply detection equipment lacks the ability to detect other water quality parameters.

[0056] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
