Description

Technical Field

[0001] This utility model relates to the field of detection technology, and in particular to an integrated detection device. Background Technology

[0002] In the field of detection technology, traditional detection devices, such as sensors, have relatively limited detection functions, capable of measuring only a single specific parameter of a liquid. Such single-function detection devices have significant limitations: they cannot simultaneously detect multiple parameters of a liquid, requiring multiple independent detection devices to be installed for each parameter, increasing the overall installation space and making installation complex. Utility Model Content

[0003] Therefore, it is necessary to provide an integrated detection device to address the problem that detection devices cannot simultaneously detect multiple parameters of liquids, which leads to the need to install multiple independent detection devices, increases the overall installation space of the detection device, and makes the installation more complicated.

[0004] An integrated detection device includes: a housing assembly having a flow cavity, an inlet and an outlet, the inlet, the flow cavity, and the outlet being sequentially connected; the housing assembly having a first assembly space communicating with the flow cavity; and a second assembly space communicating with the flow cavity; a conductivity detection component disposed on the housing assembly and located in the first assembly space, with a portion of the conductivity detection component located within the flow cavity, the conductivity detection component being used to detect the conductivity of a liquid; and a pH detection component disposed on the housing assembly and located in the second assembly space, with a portion of the pH detection component located within the flow cavity, the pH detection component being used to detect the acidity or alkalinity of the liquid within the flow cavity.

[0005] This application discloses an integrated detection device that can detect the TDS content in a liquid by incorporating a conductivity detection component. TDS refers to the total amount of solutes in water. By integrating the conductivity and pH detection components within the same housing, the device can simultaneously detect both conductivity and pH of the liquid. Compared to traditional detection devices, such as sensors that can only detect a single liquid parameter, this design offers superior performance and greater practicality. This design effectively avoids or reduces the space-consuming and cumbersome installation problems associated with separate installations required by traditional single-function detection devices. Since the detection parts of both the conductivity and pH detection components extend into the same flow chamber, they can simultaneously detect the liquid within the flow chamber, improving measurement consistency and accuracy and avoiding errors caused by different detection paths. The conductivity and pH detection components are respectively fixed in a first and second assembly space, resulting in a more compact overall structure, reduced installation space requirements, and simplified installation and maintenance processes. The integrated detection device of this application, through its modular and integrated design, facilitates rapid component replacement and maintenance and enables adaptive control of disinfectant concentration based on a host integrated control algorithm. Moreover, it can be adapted to a variety of products, such as water purification equipment, electrochemical equipment, and other water quality testing devices, and has high practicality and versatility.

[0006] In one embodiment, an ORP detection component is also included. This ORP detection component is disposed on the housing assembly, with a portion located within the flow chamber. The ORP detection component is used to detect the redox potential of the liquid within the flow chamber. By adding an ORP detection component to the housing assembly, the device can simultaneously detect the liquid's conductivity, pH value, and redox potential, further expanding its detection capabilities and meeting more complex liquid monitoring needs. Because a portion of the ORP detection component is located within the flow chamber, it can work together with the conductivity and pH detection components to detect the liquid within the flow chamber, improving measurement consistency and accuracy. This design helps improve the overall structural compactness, reduces space occupation, and simplifies subsequent maintenance procedures.

[0007] In one embodiment, a reference electrode assembly is also included, which is disposed on the housing assembly, with a portion of the reference electrode assembly located within the flow chamber. The reference electrode assembly provides a stable potential reference for the pH and ORP detection components, effectively improving the accuracy of pH and redox potential measurements. Since a portion of the reference electrode assembly is located within the same flow chamber as the water source detected by the conductivity, pH, and ORP detection components, inconsistencies in measurement conditions due to differences in installation location are avoided, thus improving data reliability.

[0008] In one embodiment, the housing assembly has a third assembly space that communicates with the flow cavity, and the ORP detection component is disposed on the housing assembly and located in the third assembly space. The third assembly space provides a stable mounting position for the ORP detection component, making the overall structure more compact.

[0009] In one embodiment, the housing assembly has a fourth mounting space that communicates with the flow cavity, and the reference electrode assembly is disposed on the housing assembly and located in the fourth mounting space. The fourth mounting space provides a stable mounting position for the reference electrode assembly, resulting in a more compact overall structure.

[0010] In one embodiment, the housing assembly has an inlet channel and an outlet channel, with the inlet, the inlet channel, and the flow chamber sequentially connected, and the flow chamber, the outlet channel, and the outlet sequentially connected. By providing independent inlet and outlet channels, the stability of the liquid delivery path is ensured, as is the fluid stability of the flow chamber. Fluid stability in the detection area helps reduce the impact of turbulence or stagnation on measurement accuracy. Preferably, the diameter of the inlet channel is 4.5 mm, and the diameter of the outlet channel is 5.5 mm.

[0011] In one embodiment, the water inlet channel is located at the bottom of the flow chamber or near the bottom of the flow chamber; the water outlet channel is located at the top of the flow chamber or near the top of the flow chamber. By positioning the water inlet channel at the bottom of the flow chamber and the water outlet channel at the top, liquid enters from the bottom and exits from the top, utilizing the height difference between the inlet and outlet water to create water flow deposition. This allows the liquid to completely submerge all the aforementioned detection components, enhancing the detection effect.

[0012] In one embodiment, the housing assembly includes a flow-through housing and a probe bracket. The flow-through housing has an inlet and an outlet. The probe bracket is mounted on the flow-through housing. Both the conductivity detection component and the pH detection component are mounted on the probe bracket. The probe bracket and the flow-through housing enclose the flow-through cavity. The probe bracket has a first assembly space and a second assembly space. The separate design of the flow-through housing and the probe bracket makes disassembly and assembly simpler and more convenient, facilitating independent processing, maintenance, and replacement of each component, thus improving manufacturing and assembly flexibility. Integrating the conductivity detection component and the pH detection component onto the probe bracket results in a more compact structure and a smaller overall footprint.

[0013] In one embodiment, the flow-through housing has an opening that communicates with the flow-through cavity, and the probe bracket is disposed on the flow-through housing and located at the opening. By positioning the probe bracket at the opening, the flow-through cavity can be sealed, preventing liquid leakage and thus ensuring detection efficiency.

[0014] In one embodiment, a first sealing ring is further included. The first sealing ring is disposed on the flow-through housing and / or the probe holder, located between the flow-through housing and the probe holder. The first sealing ring is used to seal the gap between the flow-through housing and the probe holder. By sealing the gap between the flow-through housing and the probe holder with the first sealing ring, the overall sealing performance and reliability of the product are improved, effectively preventing liquid leakage from affecting the detection efficiency. This design ensures the airtightness of fluid flow inside the flow-through cavity, avoiding flow loss or pressure changes due to leakage, and maintaining the stability of the detection environment.

[0015] In one embodiment, the flow-through housing is threadedly connected to the probe bracket. This threaded connection provides a stable mechanical fastening force, ensuring a tight fit between the flow-through housing and the probe bracket, preventing loosening or displacement due to vibration or pressure changes, improving the overall structural stability, and thus making the detection process more stable. Furthermore, the threaded connection facilitates quick installation and disassembly, simplifying assembly and maintenance procedures.

[0016] In one embodiment, the flow-through housing includes a housing body, an inlet pipe, and an outlet pipe. The probe bracket is mounted on the housing body, and the probe bracket and the housing body together form the flow-through cavity. Both the inlet pipe and the outlet pipe are mounted on the housing body. The inlet pipe has an inlet, and the outlet pipe has an outlet. The arrangement of the inlet and outlet pipes allows for smoother water intake and exhaust processes, maintaining the stability of liquid flow and thus improving detection efficiency.

[0017] In one embodiment, the water inlet pipe is provided with a first sealing groove surrounding the water inlet pipe, and also includes a second sealing ring disposed on the water inlet pipe and located at the first sealing groove. The cooperation between the second sealing ring and the first sealing groove ensures the sealing between the water inlet pipe and external components, prevents liquid leakage, ensures sufficient water pressure and flow, and helps to ensure detection efficiency.

[0018] In one embodiment, the water outlet pipe is provided with a second sealing groove surrounding the water outlet pipe, and also includes a third sealing ring disposed on the water outlet pipe and located at the second sealing groove. The cooperation between the third sealing ring and the second sealing groove ensures the sealing between the water outlet pipe and external components, prevents liquid leakage, ensures sufficient water pressure and flow, and helps to ensure detection efficiency.

[0019] In one embodiment, the outer surface of the conductivity detection component abuts against the space wall of the first assembly space. This abutment between the outer surface of the conductivity detection component and the space wall of the first assembly space effectively improves sealing. Attached Figure Description

Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

The pH detection component 3 is used to detect the acidity or alkalinity of the liquid within the flow cavity 102.

[0047] This application discloses an integrated detection device that can detect the TDS content in a liquid by setting up a conductivity detection component 2. TDS refers to the total amount of solutes in water. By integrating the conductivity detection component 2 and the pH detection component 3 within the same housing component 1, the integrated detection device can simultaneously detect the conductivity and pH of the liquid. Compared with traditional detection devices, such as sensors, which can only detect a single liquid parameter, this design has superior performance and greater practicality. This design effectively avoids or reduces the problems of large space occupation and cumbersome installation caused by the separate installation of traditional single-function detection devices. Since the detection parts of the conductivity detection component 2 and the pH detection component 3 both extend into the same flow cavity 102, the liquid in the flow cavity 102 can be detected together, improving the consistency and accuracy of the measurement and avoiding errors caused by different detection paths.

By adding the ORP detection component 4 to the housing assembly 1, the device can simultaneously detect the conductivity, pH value, and redox capacity of the liquid, further expanding the detection function and meeting more complex liquid monitoring needs. Since a portion of the ORP detection component 4 is located within the flow cavity 102, it can work together with the conductivity detection component 2 and the pH detection component 3 to detect the liquid within the flow cavity 102, improving the consistency and accuracy of the measurements. This design helps to improve the overall structural compactness, reduce space occupation, and simplify subsequent maintenance procedures.
