Description

Technical Field

[0001] This utility model relates to the technical field of electronic switches, specifically a novel combined structure for detecting water quality and controlling water level. Background Technology

[0002] Liquid level control is a crucial element in many scenarios of industrial production and daily life. As a widely used liquid level control device, the float switch plays a key role in many fields due to its significant advantages such as simple structure, reliable operation, and affordable price.

[0003] The working principle of a float switch is based on the physical property of buoyancy. It mainly consists of a float, a connecting rod, and a sensor switch. When the liquid level changes, the float moves up and down with the rise and fall of the liquid level. The displacement of the float is transmitted to the sensor switch through the connecting rod, which then causes the sensor switch to take corresponding actions, thereby realizing the monitoring and control of the liquid level.

[0004] In the industrial sector, float switches are commonly used for level control in various containers such as water tanks, pools, and oil tanks, ensuring that the liquid remains within a suitable range and guaranteeing stable operation of the production process. For example, in chemical production, it can control the liquid level in reaction vessels to prevent overflow or excessively low levels from affecting the reaction effect. In wastewater treatment plants, float switches can be used to monitor the liquid level in wastewater tanks, enabling automatic start and stop of water pumps and improving wastewater treatment efficiency. In daily life, float switches are also widely used for level control in household water tanks (such as water tanks in water dispensers, blenders, humidifiers, and other household appliances), fish tanks, and other equipment, bringing convenience to people's lives.

[0005] However, existing float switches have significant functional limitations. They focus solely on monitoring and controlling liquid levels and do not have water quality monitoring capabilities. In many practical applications, it is necessary not only to control the liquid level but also to understand the quality of the liquid in real time. For example, in drinking water supply systems, in addition to ensuring that there is sufficient water in the tank, it is also necessary to ensure that the water quality meets hygiene standards. In the aquaculture industry, the quality of water directly affects the growth and health of aquatic organisms, and farmers need to keep track of indicators such as pH, dissolved oxygen, and total dissolved solids (TDS) in the water.

[0006] Currently, water quality testing requires the installation of specialized testing devices, such as TDS probes, pH sensors, and dissolved oxygen sensors. These additional devices not only increase the complexity and cost of the system but also require additional installation space and maintenance. Furthermore, the coordinated operation of multiple independent devices may lead to signal interference, affecting the accuracy and reliability of the test results. In addition, the installation locations and methods of different devices may vary, which also increases the difficulty of system design and installation.

[0007] This utility model was proposed in response to the shortcomings of the existing technology. Utility Model Content

[0008] Regarding the aforementioned technical issue that existing float switches do not have water quality monitoring capabilities, and that additional detection devices (such as TDS detection probes) are required if water quality testing is needed, the technical problem remains.

[0009] The technical solution adopted by this utility model to solve its technical problem is:

The first welding part and the second welding part are disposed at both ends of the first circuit, and the second welding part can be connected to a wire or a plug terminal.

[0015] As described above, a novel combined structure for detecting water quality and controlling water level is provided on the surface of the circuit board, which is electrically connected to a magnetic induction actuator. The second conductive connection part includes a third welding part, a second circuit, and a fourth welding part. The third welding part is welded to the magnetic induction actuator. The third welding part and the fourth welding part are located at both ends of the second circuit. The fourth welding part can be connected to a wire or a terminal block.

[0016] In the novel combined structure for detecting water quality and controlling water level described above, the second circuit and the first circuit are respectively disposed on opposite sides of the circuit board.

[0017] As described above, in a novel combined structure for detecting water quality and controlling water level, the second circuit and the first circuit are located on the same board surface.

[0018] As described above, in a novel combined structure for detecting water quality and controlling water level, the TDS water quality monitoring probe is connected to a first conductive connection part, which can be connected to a wire or a plug terminal.

[0019] In the novel combined structure for detecting water quality and controlling water level described above, the magnetic sensing actuator is a reed switch or a Hall switch.

[0020] The beneficial effects of this utility model are as follows:

[0021] This utility model discloses a novel combined structure for detecting water quality and controlling water level, relating to the technical field of electronic switches.

Detailed Implementation

[0033] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0034] like Figures 1 to 10 As shown, this embodiment presents a novel combined structure for detecting water quality and controlling water level, including a housing 1. A float with a magnetic component is fitted on the outer side of the housing 1, and the float can reciprocate along the axial direction of the housing 1. The housing 1 has a mounting cavity 11, and a circuit board 2 is installed in the mounting cavity 11. The circuit board 2 has a magnetic induction actuator 3 corresponding to the magnetic component. The mounting cavity 11 also has a TDS water quality monitoring probe 4. The top of the housing 1 has an extension hole 12 for one end of the TDS water quality monitoring probe 4 to extend out. That is, this design adds a TDS probe to the float switch, so that the float switch can simultaneously detect water quality and control water level.

[0035] Preferably, this combined structure retains the water level control function of a traditional float switch. When the liquid level changes, the float with a magnetic component, sleeved on the outside of the housing 1, will reciprocate along the axial direction of the housing 1 as the liquid level rises and falls. The magnetic induction actuator 3, mounted on the circuit board 2 and corresponding to the magnetic component, can sense the change in the magnetic field of the magnetic component on the float. When the float rises or falls to a specific position, the relative position between the magnetic component and the magnetic induction actuator 3 changes, causing the magnetic induction actuator 3 to generate a corresponding action signal. This signal is processed and transmitted through the circuit board 2, thereby realizing the control of external equipment (such as water pumps, valves, etc.) to achieve the purpose of controlling the water level. For example, when the water level rises to the set upper limit position, the magnetic induction actuator 3 triggers a signal to control the water pump to stop filling the water tank; when the water level drops to the set lower limit position, the magnetic induction actuator 3 triggers a signal again to start the water pump to fill the water tank.

[0036] Preferably, a TDS water quality monitoring probe 4 is installed in the mounting cavity 11, and an extension hole 12 is provided on the top of the housing 1. One end of the TDS water quality monitoring probe 4 extends out of the housing 1 through the extension hole 12 and directly contacts the liquid to be tested. The TDS water quality monitoring probe 4 can detect the total dissolved solids content in the liquid. Its working principle is based on the relationship between the conductivity of the solution and the total dissolved solids content. The probe 4 transmits the detected conductivity signal to the circuit board 2. The circuit board 2 processes and analyzes the signal, converts the conductivity signal into the corresponding TDS value, and outputs the water quality detection data through the corresponding output interface so that the user can understand the water quality status in real time.

[0037] The biggest advantage of this design is that it integrates water level control and water quality detection functions into one device. This new combined structure integrates the two functions, which greatly simplifies the system structure and installation process, reduces the overall cost, and reduces potential signal interference and communication failures between multiple independent devices.

[0038] Since water level control and water quality detection functions are implemented in the same device, it can monitor water level and water quality in real time at the same time. Users can understand the water level and keep abreast of changes in water quality, which makes it easier to make more accurate and timely decisions based on the actual situation.

[0039] This integrated device has a wider range of applications and greater flexibility. It can be used in various situations that require simultaneous water level control and water quality testing, such as household drinking water tanks, liquid storage containers in industrial production, and agricultural irrigation systems. Users can easily install the device in different systems according to their actual needs to meet diverse application requirements.

[0040] like Figures 1 to 10 As shown, the TDS water quality monitoring probe 4 in this embodiment is connected to a first conductive connection part 41, which is electrically connected to the circuit board 2.

[0041] Preferably, the TDS water quality monitoring probe 4 is used to detect the total dissolved solids content in the liquid. When it is working, it generates an electrical signal related to the conductivity of the solution. The first conductive connection part 41 acts as a bridge to connect the TDS water quality monitoring probe 4 to the circuit board 2.

[0042] When the TDS water quality monitoring probe 4 comes into contact with the liquid to be tested, it will generate a corresponding conductivity signal based on factors such as the ion concentration in the liquid. This electrical signal is transmitted to the circuit board 2 through the first conductive connection part 41. The circuit board 2 usually integrates a signal processing circuit, which will amplify, filter, and perform analog-to-digital conversion on this electrical signal, converting the electrical signal into a digital signal, and converting it into the corresponding TDS value according to a pre-set algorithm. Finally, the water quality detection result is presented to the user through a suitable output interface (such as a display screen, communication interface, etc.).

[0043] The first conductive connection part 41 provides a stable electrical connection channel between the TDS water quality monitoring probe 4 and the circuit board 2. In practical applications, the liquid environment may experience vibration, shaking, or other disturbances. Without a dedicated conductive connection part, the connection between the probe 4 and the circuit board 2 may become loose or have poor contact, leading to unstable signal transmission and affecting the accuracy of the water quality detection results. The first conductive connection part 41 ensures a tight and reliable connection between the probe 4 and the circuit board 2, enabling the detection signal to be stably transmitted to the circuit board 2 for processing.

[0044] like Figures 1 to 10 As shown, the first conductive connection part 41 in this embodiment includes a first welding part 411 disposed on the circuit board 2, and the TDS water quality monitoring probe 4 is connected to the first welding part 411 by welding.

[0045] Preferably, the first welding part 411 is a part on the circuit board 2 specifically designed to connect the probe 4. Through the welding process, the TDS water quality monitoring probe 4 is firmly connected to the first welding part 411. In this way, the electrical signal generated by the probe 4 can be stably transmitted to the circuit board 2 through the conductive path formed by welding. The circuit on the circuit board 2 will further process this electrical signal.

[0046] Welding is a permanent connection method that can form a very low-resistance conductive connection between the TDS water quality monitoring probe 4 and the first welded part 411. This means that the electrical signal will hardly be attenuated or distorted during transmission due to connection problems, ensuring the stability and reliability of signal transmission. The welded connection will not loosen due to vibration, shaking or the passage of time, thus ensuring that the water quality monitoring system can work stably for a long time and accurately reflect the TDS status of the water quality.

[0047] Welding not only provides a stable electrical connection but also has strong mechanical connection strength. It can firmly fix the TDS water quality monitoring probe 4 to the circuit board 2, so that it can withstand certain external forces without falling off or shifting. In practical applications, water quality monitoring equipment may be subjected to various mechanical shocks and vibrations, such as collisions during installation and slight vibrations during equipment operation. Welded connections can effectively resist these external forces, ensuring that the connection between probe 4 and circuit board 2 is not affected, thus improving the mechanical stability and reliability of the entire system.

[0048] The welded interface is an atomic-level bond with very low contact resistance. This low contact resistance reduces energy loss during signal transmission and improves signal transmission efficiency. By welding, the contact resistance can be minimized, ensuring that the weak electrical signal generated by probe 4 can be effectively transmitted to circuit board 2 for processing, thereby improving the accuracy and sensitivity of water quality monitoring.

[0049] The welding connection does not require additional connecting parts (such as plugs, sockets, etc.), and the probe 4 can be directly connected to the circuit board 2, saving internal space. In addition, the welding process is relatively simple, and the material and labor costs are relatively low, which helps to reduce the manufacturing cost of the entire water quality monitoring system.

[0050] Preferably, in other embodiments, the first conductive connection part 41 includes a socket on the circuit board 2 and a plug terminal on the probe 4. Using the first conductive connection part 41 for electrical connection makes the installation and removal of the TDS water quality monitoring probe 4 more convenient. During the equipment installation process, the probe 4 can be installed simply by correctly connecting the probe 4 to the corresponding interface on the circuit board 2. When the probe 4 malfunctions and needs to be replaced, it can also be easily removed from the circuit board 2 for repair or replacement with a new probe, reducing the difficulty and cost of maintenance.

[0051] This design embodies a certain modular concept. The TDS water quality monitoring probe 4 and the circuit board 2 can be regarded as two relatively independent modules, which are connected by the first conductive connection part 41. This design facilitates product upgrades and improvements, and the appropriate design can be selected according to actual needs.

[0052] like Figures 1 to 10 As shown, the first conductive connection part 41 in this embodiment also includes a first circuit 412 and a second soldering part 413 disposed on the surface of the circuit board 2. The first soldering part 411 and the second soldering part 413 are disposed at the two ends of the first circuit 412 respectively, and the second soldering part 413 can be connected to a wire or a plug terminal.

[0053] Preferably, after the TDS water quality monitoring probe 4 is welded to the first welding part 411, when the probe 4 detects the total dissolved solids (TDS) content in the water and converts it into an electrical signal, the electrical signal is first transmitted to the first circuit 412 through the first welding part 411. The first circuit 412 is a pre-designed conductive line on the circuit board 2, which has specific electrical characteristics and can stably transmit the electrical signal from the first welding part 411 to the second welding part 413. The second welding part 413 can be connected to a wire or a plug terminal. If a wire is connected, the electrical signal will be further transmitted to other devices or modules that need to receive the signal, such as signal processing units, display devices, etc. If a plug terminal is connected, the plug terminal can be easily connected to other devices with matching interfaces to realize the transmission of electrical signals and communication between devices.

[0054] Preferably, the first circuit 412 plays a key role in connection and conduction throughout the signal transmission process. It ensures that the electrical signal collected from the probe 4 can be accurately and stably transmitted from the first welding part 411 to the second welding part 413, and then transmitted to subsequent equipment or modules, thus ensuring the integrity of the circuit function of the entire water quality monitoring system.

[0055] Preferably, by providing a second welding part 413 and enabling it to connect to wires or plug terminals, the flexibility of signal transmission is greatly improved. In different application scenarios, different connection methods can be selected according to actual needs. For example, when water quality monitoring data needs to be transmitted to devices at a long distance, wires can be used for connection to achieve long-distance signal transmission; when it is necessary to quickly dock and communicate with other devices, plug terminals can be used to conveniently and quickly complete the connection and disassembly between devices, facilitating the installation, debugging and maintenance of the system.

[0056] Preferably, this design enables the water quality monitoring system to have better scalability and upgradeability. With the development of technology and changes in application requirements, it may be necessary to expand or upgrade the system's functions. By connecting the second welding part 413 to the wire or plug terminal, new devices or modules can be easily connected to the system to expand the system's functions. For example, a more advanced signal processing module can be connected to improve the accuracy and analysis capabilities of water quality monitoring, or a wireless communication module can be connected to realize remote data transmission and monitoring functions.

[0057] Preferably, if a fault occurs during signal transmission, since the first circuit 412 separates the first welding part 411 and the second welding part 413, it is convenient to locate and troubleshoot the fault. By detecting the signal conditions at both ends of the first circuit 412, it can be quickly determined whether the fault occurs at the connection between the probe 4 and the first welding part 411, the first circuit 412 itself, or between the second welding part 413 and subsequent connected devices. Moreover, even if the second welding part 413 and its connected wires or terminals fail, it will not directly affect the connection between the probe 4 and the first welding part 411 or the normal operation of the first circuit 412, reducing the impact of the fault on the entire system and improving the reliability and maintainability of the system.

[0058] Preferably, the arrangement of the first circuit 412 allows for a reasonable layout of the connection part of the probe 4 and the subsequent signal transmission part on the circuit board 2. This avoids too many lines and connection points being concentrated in one place, making the wiring of the circuit board clearer and more organized, reducing the possibility of electromagnetic interference and signal crosstalk, and improving the electrical performance and stability of the circuit board. At the same time, a reasonable layout is also beneficial to the heat dissipation of the circuit board and the operation during the manufacturing process.

[0059] Preferably, the second welding part 413 can be connected to a wire or plug terminal, so that the system can be compatible with different interface standards. Different devices may have different interface types and specifications. By selecting appropriate wires or plug terminals, it is possible to connect and communicate with various devices, which improves the versatility and applicability of the water quality monitoring system and can meet the needs of different users and application scenarios.

[0060] like Figures 1 to 10 As shown, the circuit board 2 of this embodiment has a second conductive connection part 21 that is electrically connected to the magnetic induction actuator 3. The second conductive connection part 21 includes a third welding part 211, a second circuit 212, and a fourth welding part 213. The third welding part 211 is welded to the magnetic induction actuator 3. The third welding part 211 and the fourth welding part 213 are respectively disposed at both ends of the second circuit 212. The fourth welding part 213 can be connected to a wire or a terminal block. That is, the magnetic induction actuator 3 and the TDS water quality monitoring probe 4 are electrically connected by corresponding wires or terminals.

[0061] Preferably, when the external magnetic field changes, the magnetic induction actuator 3 generates a corresponding electrical signal. This electrical signal is transmitted to the second circuit 212 through the third welding part 211. The second circuit 212 acts as a conductive channel, conducting the electrical signal from the third welding part 211 to the fourth welding part 213. The wires or terminals connected to the fourth welding part 213 further transmit the electrical signal to other devices or modules that require the signal, such as control systems, alarm devices, data acquisition devices, or display screens, to achieve corresponding control or warning functions.

[0062] The TDS water quality monitoring probe 4 converts the detected water quality information into an electrical signal. This electrical signal is transmitted through the first conductive connection part 41 (such as the first welding part 411, the first circuit 412 and the second welding part 413 mentioned above) to the corresponding wire or plug terminal. The wire or plug terminal then transmits the signal to subsequent processing equipment, such as a control system, alarm device, data acquisition unit or display screen, etc.

[0063] The magnetic induction actuator 3 and the TDS water quality monitoring probe 4 independently collect different types of information (magnetic field information and water quality information), and convert this information into electrical signals. These signals are then transmitted to the corresponding processing devices through their respective conductive connections and wires or terminals. The processing devices can perform comprehensive analysis and judgment based on the received signals, thereby enabling control and management of the entire system. For example, the operating status of the equipment can be adjusted according to the water quality and magnetic field environment.

[0064] The magnetic induction actuator 3 and the TDS water quality monitoring probe 4 are connected to wires or terminals through independent conductive connectors, forming relatively independent modules. During installation, these two modules can be installed and debugged separately, reducing installation difficulty and complexity. During maintenance, if one module malfunctions, only that module needs to be inspected and repaired without affecting the normal operation of other modules, thus improving maintenance efficiency and reducing downtime.

[0065] The magnetic induction actuator 3 and the TDS water quality monitoring probe 4 use independent conductive connectors and wires or terminals for signal transmission, which avoids the interference that may occur when two different types of signals are transmitted in the same line. For example, the electrical signal generated by magnetic induction may interfere with the weak water quality signal generated by the TDS water quality monitoring probe. Independent transmission can effectively reduce the impact of such interference and ensure the accuracy and stability of signal transmission.

[0066] Each module can be connected by selecting appropriate wires or terminals according to actual needs, which facilitates the adjustment of signal transmission paths and methods. For example, different lengths of wires can be selected according to the distance between devices, or appropriate terminals can be selected according to the interface type of the connected devices, improving the system's flexibility and adaptability.

[0067] like Figures 1 to 10 As shown, in this embodiment, the second circuit 212 and the first circuit 412 are respectively disposed on opposite sides of the circuit board 2. That is, the magnetic induction actuator 3 (reed switch or Hall switch and other components) and the TDS water quality monitoring probe 4 use the same circuit board 2. Both sides of the circuit board 2 are provided with electrical network copper film (i.e., the second circuit 212 and the first circuit 412). The magnetic induction actuator 3 (reed switch or Hall switch and other components) is energized by the electrical network copper film (first circuit 412) on one side of the circuit board 2, while the TDS water quality monitoring probe 4 is energized by the electrical network copper film (second circuit 212) on the other side of the circuit board 2.

[0068] Preferably, the magnetic induction actuator and the TDS water quality monitoring probe are integrated on the same circuit board 2, avoiding the use of multiple circuit boards and greatly saving the space occupied by the device. This is very advantageous for some application scenarios with high space requirements, such as miniaturized water quality monitoring equipment and compact smart home systems.

[0069] The integration of two different functional modules on the circuit board makes the entire system more compact and integrated. This not only reduces the size of the device but also reduces the complexity of the connections between devices, thereby improving the overall stability and reliability of the system.

[0070] Preferably, the first circuit 412 and the second circuit 212 are respectively disposed on opposite sides of the circuit board 2, which can achieve electromagnetic isolation to a certain extent. The magnetic induction actuator will generate a certain electromagnetic interference when it is working, and the TDS water quality monitoring probe detects a weak water quality signal, which is easily affected by electromagnetic interference. By distributing their circuits on different sides, the propagation of electromagnetic interference can be effectively reduced, ensuring the accuracy and stability of the TDS water quality monitoring probe detection results.

[0071] Different types of signals are transmitted in the circuits on opposite sides of the circuit board, avoiding crosstalk between signals.

[0072] The space on both sides of the circuit board provides more options and flexibility for circuit wiring. The wiring of the first circuit 412 and the second circuit 212 can be planned more rationally according to the actual position and connection requirements of the magnetic induction actuator and the TDS water quality monitoring probe, reducing wiring intersections and overlaps, reducing wiring difficulty, and improving wiring efficiency.

[0073] Integrating two functional modules on the same circuit board reduces the number of circuit boards and connection links, simplifies the manufacturing process, helps reduce production costs and improve production efficiency, and also facilitates quality inspection and debugging of the entire circuit board.

[0074] Furthermore, the various functional modules work together on the same circuit board 2, making signal transmission more stable and reliable, thus improving the reliability and stability of the entire system. In addition, the integrated design also facilitates equipment maintenance and management, reducing maintenance costs and difficulties.

[0075] Preferably, in other embodiments, the second circuit 212 and the first circuit 412 are disposed on the same surface of the circuit board 2, which can reduce the double-sided processing requirements in the circuit board manufacturing process. This reduces the complexity and difficulty of manufacturing, improves production efficiency, and also reduces quality problems that may be caused by double-sided processing, such as interlayer alignment errors.

[0076] During assembly, the single-board design makes it easier to install the magnetic induction actuator and the TDS water quality monitoring probe. The devices can be soldered and connected on the same side without frequently flipping the circuit board, which improves the speed and accuracy of assembly and reduces the probability of errors during assembly.

[0077] Since circuit design and wiring only need to be done on one side of the circuit board, the manufacturing cost of the circuit board is reduced. No additional processes are needed to ensure the conductivity and insulation of the circuits on both sides, and the thickness requirements of the circuit board are also reduced, thereby reducing the amount of raw materials used.

[0078] The first circuit 412 and the second circuit 212 on the same board can be connected and integrated more easily, reducing the use of vias, adapters and other components for connecting circuits on different boards, and further reducing costs.

[0079] By placing the two circuits on the same board, the connection distance between the magnetic induction actuator and the TDS water quality monitoring probe and their respective circuits is relatively short, and the signal transmission path is shortened. This helps to reduce signal attenuation and distortion during transmission, improve the quality and stability of signal transmission, and thus improve the performance and reliability of the entire system.

[0080] The circuit layout on the same board makes it easier to achieve signal synchronization and interaction between the first circuit 412 and the second circuit 212. It is also easier to design signal coupling and feedback mechanisms to achieve collaborative work and data interaction between the two functional modules. For example, it can more quickly adjust the parameters or frequency of TDS water quality monitoring based on the magnetic induction signal. The appropriate design can be selected according to actual needs.

[0081] like Figures 1 to 10As shown, a sealing medium is provided between the TDS water quality monitoring probe 4 and the protrusion hole 12 in this embodiment. The sealing medium can be a sealing ring or a potting compound, etc. It can be achieved by setting a sealing ring between the TDS water quality monitoring probe 4 and the protrusion hole 12, or by assembling the circuit board 2 containing the magnetic induction actuator 3 and the TDS water quality monitoring probe 4 into the float switch housing 1, and then further potting the housing 1 with the potting compound so that the potting compound can fill the gap between the TDS water quality monitoring probe 4 and the protrusion hole 12.

[0082] Preferably, when a sealing ring is used for sealing, the sealing ring is usually an annular material with a certain elasticity. It is installed in the gap between the TDS water quality monitoring probe 4 and the protrusion hole 12. During the assembly process, the TDS water quality monitoring probe 4 is installed into the protrusion hole 12 under certain pressure, which causes the sealing ring to be squeezed and deformed. The elasticity of the sealing ring makes it fit tightly against the outer surface of the TDS water quality monitoring probe 4 and the inner surface of the protrusion hole 12, forming a continuous sealing barrier to prevent water, dust, moisture and other external substances from entering the float switch housing 1 from this gap.

[0083] Preferably, the potting seal is performed after the circuit board 2, which contains the magnetic induction actuator 3 and the TDS water quality monitoring probe 4, is assembled into the float switch housing 1. A specific potting compound is injected into the float switch housing 1. The compound is fluid and will gradually fill the gap between the TDS water quality monitoring probe 4 and the protrusion hole 12, as well as other gaps in the housing. Over time, the compound will undergo a curing reaction to form a hard and well-sealed whole. The cured compound completely seals the gap between the TDS water quality monitoring probe 4 and the protrusion hole 12, preventing the intrusion of external substances.

[0084] Float switches are typically used in liquid environments, such as water tanks and pools. By setting a sealing medium between the TDS water quality monitoring probe 4 and the protrusion hole 12, water can be effectively prevented from entering the float switch housing 1 through the protrusion hole 12. Water intrusion may cause problems such as short circuit of the circuit board 2, damage to the magnetic induction actuator 3 and the TDS water quality monitoring probe 4, thereby affecting the normal operation of the entire float switch. The sealing design can greatly improve the reliability and stability of the float switch in humid or liquid environments.

[0085] In some industrial environments or dusty situations, dust and impurities may enter the float switch through the protrusion hole 12. This dust and impurities may adhere to the circuit board 2 or affect the performance of the magnetic induction actuator 3 and the TDS water quality monitoring probe 4. The sealing medium can prevent the entry of dust and impurities, protect the internal components from contamination, and extend the service life of the float switch.

[0086] For the TDS water quality monitoring probe 4, its measurement accuracy is closely related to the surrounding environment. The sealed design can prevent external factors from interfering with the measurement environment, such as preventing water fluctuations and the mixing of impurities from affecting the measurement results. Maintaining a relatively stable measurement environment can improve the accuracy and reliability of TDS water quality monitoring, and make the measurement results more realistically reflect the water quality situation.

[0087] The sealing medium not only serves a sealing function, but also provides a certain degree of fixation for the TDS water quality monitoring probe 4. The compression of the sealing ring or the curing of the potting compound can firmly fix the TDS water quality monitoring probe 4 in the protrusion hole 12, preventing the probe from shaking or shifting during use. This helps to maintain the correct position and posture of the probe, ensuring its normal operation, and also enhances the overall structural stability of the float switch.

[0088] In applications involving vibration, the sealing medium can absorb and buffer vibration energy, reducing the impact of vibration on the TDS water quality monitoring probe 4 and internal components. This helps improve the reliability and stability of the float switch in vibration environments, ensuring its normal operation under various complex conditions.

[0089] You can choose the appropriate design based on your actual needs.

[0090] Preferably, in other embodiments, the TDS water quality monitoring probe 4 is connected to a first conductive connection part 41, which can be connected to a wire or a plug terminal. That is, the TDS water quality monitoring probe 4 and the circuit board 2 are independent of each other. The TDS water quality monitoring probe 4 is further wired through the first conductive connection part 41. The TDS water quality monitoring probe 4 can first be sealed and assembled with the protrusion hole 12 on the float switch housing 1 by injection molding. Then, the circuit board 2 with the magnetic induction actuator 3 is assembled into the float switch housing 1, and then glue is poured into the housing 1.

[0091] Preferably, during the injection molding process, the molten plastic material fills the gap between the TDS water quality monitoring probe 4 and the protrusion hole 12. After cooling and solidification, it forms a sealed whole, preventing water, dust and other external substances from entering the float switch housing 1. Then, the circuit board 2 equipped with the magnetic induction actuator 3 is assembled into the float switch housing 1, and then glue is poured into the housing 1. The glue pouring further enhances the internal sealing effect, and also protects and fixes the circuit board 2 and internal components.

[0092] Preferably, with this design, the TDS water quality monitoring probe 4 and the circuit board 2 are independent of each other and can be produced and processed separately. The TDS water quality monitoring probe 4 can be injection molded and sealed first. This process can be carried out independently of the assembly of the circuit board 2, which reduces mutual interference in the production process and improves the overall production efficiency.

[0093] If the TDS water quality monitoring probe 4 malfunctions, since it is independent of the circuit board 2, the TDS water quality monitoring probe 4 can be easily removed from the float switch housing 1 for repair or replacement simply by disconnecting the wire or plug terminal at the first conductive connection part 41, without having to disassemble and inspect the entire circuit board 2, thus reducing repair costs and difficulty.

[0094] Since the TDS water quality monitoring probe 4 can be additionally wired through the first conductive connection part 41, the wiring is more flexible. The appropriate wire length and direction can be selected according to the actual installation space and wiring requirements, avoiding the wiring difficulties caused by the layout limitations of the circuit board 2, and making the electrical connection of the entire float switch more reasonable and convenient.

[0095] You can choose the appropriate design based on your actual needs.

[0096] like Figures 1 to 10 As shown, the magnetic induction actuator 3 is a component such as a reed switch or a Hall switch, and the appropriate design can be selected according to actual needs.

[0097] Preferably, a positioning and mounting component can be provided between the circuit board 2 and the housing 1 to enable positioning and mounting of the two.

[0098] Preferably, the positioning and mounting component includes positioning protrusions on both sides of the circuit board 2 and positioning grooves on the housing 1. When the circuit board 2 is assembled into the mounting cavity 11, the positioning protrusions are engaged in the positioning grooves to achieve positioning and mounting.

[0099] Preferably, the positioning groove can be a groove provided on the inner wall of the mounting cavity 11, or it can be an assembly hole penetrating the side wall of the housing 1. A suitable design can be selected according to actual needs.

Any technical extensions or re-creations made based on this utility model are protected by this utility model. The scope of protection of this utility model is defined by the claims.
