Description

Technical Field

[0001] The utility model relates to the technical field of water immersion detection equipment, in particular to a water immersion detector. Background Art

[0002] Flood detectors are advanced monitoring devices that leverage sensor and IoT technologies to monitor flooding in real time and issue warnings when anomalies are detected, effectively preventing flooding accidents. These devices are widely used, playing a vital role in data centers, residential buildings, industrial production, agricultural irrigation, and other fields.

[0003] However, a common problem exists during the production of water detectors, particularly at the connection between the upper and lower shells. Initially, ultrasonic sealing was used to seal the shell, but this process generates vibrations of a certain frequency, which can cause internal components to fall off and break, negatively impacting functionality and performance. Therefore, many water detectors currently use epoxy potting to connect the upper and lower shells. During assembly, the lower shell is filled with transparent epoxy resin, and the light guide connected to the upper shell inside the product needs to be inserted into the liquid epoxy before it solidifies. This step often leads to the following problems: once the light guide of the indicator light is inserted into the liquid epoxy, the reaction force during the curing process causes the light guide to rise. Due to buoyancy, the light guide may not remain in its original position, resulting in a gap between the upper and lower shells. This affects the appearance and structural integrity of the water detector, and increases the defect rate during the production process. Utility Model Content

[0004] To overcome the shortcomings of the prior art, the present invention proposes a water immersion detector that solves the production problem of a gap between the upper and lower shells of current water immersion detectors, which is caused by the epoxy resin potting method used to connect the upper and lower shells. During assembly, the bottom shell is potted with transparent epoxy resin glue. Because the light guide connected to the upper shell is inserted into the liquid epoxy resin before solidification, it rises due to buoyancy during the solidification process, resulting in a gap between the upper and lower shells.

[0005] To achieve this purpose, the present invention adopts the following technical solutions:

[0006] The utility model provides a water immersion detector, which includes an upper shell, a bottom shell and a circuit board. The upper shell and the bottom shell are connected to form an outer shell. The circuit board is located inside the outer shell. The utility model also includes a support and an LED lamp. The support is installed on the circuit board. The light-emitting end of the LED lamp is located on the upper part of the support. The LED lamp is electrically connected to the circuit board through the support.

[0007] An optimal technical solution of the present invention is that the interior of the support is a hollow structure, and a through hole is opened on the upper portion of the support for the lamp pin of the LED lamp to pass through. The lamp pin of the LED lamp passes through the through hole and is electrically connected to the circuit board.

[0008] An optimal technical solution of the present invention is that the material of the support member is nylon.

[0009] An optimal technical solution of the present invention is that a receiving groove corresponding to the LED lamp is provided inside the upper shell, and the light-emitting end of the LED lamp is located in the receiving groove.

[0010] The preferred technical solution of the present invention is that the circuit boards are attached to and screwed to the bottom of the bottom shell.

[0011] An optimal technical solution of the present invention is that the lamp pins of the LED lamp are welded to the circuit board, and a welding groove is further provided at the bottom of the bottom shell, and the welding groove is located at the welding point of the lamp pins.

[0012] The preferred technical solution of the present invention is that it further includes a photoelectric probe, which is electrically connected to the circuit board. The detection end of the photoelectric probe passes through the bottom shell and is located below, and is used to detect liquid leakage.

[0013] The preferred technical solution of the present invention is that it further includes a detection electrode, which is electrically connected to the circuit board, and a detection end of the detection electrode passes through the bottom shell and is located below, for detecting leakage of the conductive liquid.

[0014] An optimal technical solution of the present invention is that the bottom shell is further provided with a centrally symmetrical base, and a mounting hole for fixing is provided on the base.

[0015] An optimal technical solution of the present invention is that the material of the upper shell is transparent PC.

[0016] Beneficial effects of the utility model:

[0017] The present utility model proposes a water immersion detector, which replaces the original light guide column by arranging a support member inside. The support member is cleverly installed on the circuit board, and the light-emitting end of the LED lamp is raised to a height close to the inner side of the upper shell, and is not shielded by the subsequently poured epoxy resin. Such a structure not only ensures that the light-emitting end of the LED lamp will not be shielded when the epoxy resin is poured, but also enables the light to smoothly penetrate the upper shell to send out a warning signal. More importantly, due to the use of the support member, the problem of the light guide column rising due to the buoyancy when inserted into the liquid epoxy resin has been fundamentally solved. As a stable structural support, the support member effectively prevents the displacement of the LED lamp and its connecting parts during the epoxy resin curing process, thereby ensuring that the upper shell and the bottom shell can be tightly connected and avoiding the generation of gaps.

[0029] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0030] Example 1

[0031] This embodiment provides a water immersion detector, such as Figure 1-8As shown, the housing comprises an upper shell 1, a lower shell 2, and a circuit board 3. The upper shell 1 and lower shell 2 are connected to form an outer shell, with the circuit board 3 located inside the outer shell. The housing also includes a support member 4 and an LED light 5. The support member 4 is mounted on the circuit board 3, with the light-emitting end 52 of the LED light 5 located above the support member 4. The LED light 5 is electrically connected to the circuit board 3 via the support member 4. The key to this innovative technical design lies in the clever mounting of the support member on the circuit board, which elevates the light-emitting end of the LED light to a height close to the inside of the upper shell and prevents it from being blocked by the subsequent epoxy resin injection. This structure not only ensures that the light-emitting end of the LED light is not blocked during the epoxy resin injection, but also allows the light to penetrate the upper shell smoothly to generate a warning signal. More importantly, the use of the support member fundamentally solves the problem of the light guide column rising due to buoyancy when inserted into the liquid epoxy resin. The support member acts as a stable structural support, effectively preventing the LED light and its connecting parts from shifting during the epoxy resin curing process, thereby ensuring a tight connection between the upper shell and the lower shell and avoiding the formation of gaps. This design not only simplifies the production process and improves the reliability and sealing of the product, but also ensures the accuracy and stability of the water immersion detector in practical applications, providing a more reliable technical guarantee for water immersion monitoring.

[0032] Preferably, the support member 4 has a cylindrical shape and a hollow interior. A through hole 41 is provided on the upper portion of the support member 4 for the pins 51 of the LED lamp 5 to pass through. The pins 51 of the LED lamp 5 are electrically connected to the circuit board 3 through the through hole 41. The hollow design inside the support member not only reduces the overall weight and lowers material costs, but also provides a more flexible spatial layout for the installation of the LED lamp. By providing corresponding through holes in the upper portion, the pins of the LED lamp can pass through and be electrically connected to the circuit board without being affected by the glue potting. This design ensures the stability of the electrical connection while avoiding short circuits or connection failures caused by improper installation. In addition, the hollow structure and through hole design also optimize the heat conduction path, helping to dissipate the heat generated by the LED lamp in a timely manner during operation, extending the service life of the LED lamp and improving the reliability and stability of the entire water immersion detector. In summary, this technical solution maximizes space utilization through ingenious structural design, improving product performance and cost-effectiveness.

[0033] Preferably, the support member 4 is made of nylon, specifically nylon 66. Nylon 66 is a translucent or opaque milky white polymer that is plastic and easily injection molded to meet various structural design requirements. Furthermore, nylon 66 has excellent electrical insulation properties, well suited to the requirements of internal insulation applications.

[0034] Preferably, a receiving groove 11 corresponding to the LED lamp 5 is provided inside the upper shell 1, and the light-emitting end 52 of the LED lamp 5 is located in the receiving groove 11. This design not only ensures the stability and accuracy of the LED lamp during installation, avoiding the problem of light scattering or poor illumination effect caused by position offset, but also effectively protects and fixes the light-emitting end of the LED lamp through precise size matching and positioning. The presence of the receiving groove can also reduce the interference of the external environment on the LED lamp, such as dust, moisture, etc., thereby improving its working reliability and service life. In addition, this design also optimizes the appearance structure of the product, making the light emission of the LED lamp more concentrated and brighter, and improving the intuitiveness and recognition of the warning effect.

[0035] Preferably, the circuit board 3 is attached to and threaded onto the bottom of the bottom case 2. This close contact between the circuit board and the bottom case allows for more sensitive detection of leaks. Furthermore, this structure not only enhances the stability of the circuit board but also significantly improves the vibration and impact resistance of the entire detector. As a mechanical connection, the threaded connection provides a stable structure and facilitates circuit board removal and maintenance. Furthermore, the close fit between the circuit board and the bottom case improves heat conduction efficiency, helping to dissipate heat generated during operation and preventing performance degradation or damage due to overheating. Specifically, the pins 51 of the LED light 5 are soldered to the circuit board 3. Solder grooves 21 are provided on the bottom of the bottom case 2, located at the solder points of the pins 51. Soldering, as a permanent connection, provides a secure, non-loose connection, thereby ensuring stable operation and a long life for the LED warning light. Furthermore, the solder grooves are designed to provide space for solder points, ensuring that the circuit board remains firmly attached to the bottom of the bottom case even when there are solder points on the bottom.

[0036] Preferably, the device also includes a photoelectric probe 6, which is electrically connected to the circuit board 3. Its detection end passes through the bottom shell 2 and is located below, and is used to detect liquid leaks. This design not only expands the functional scope of the water immersion detector but also significantly improves its detection accuracy and response speed. As a non-contact sensor, the photoelectric probe has high detection sensitivity and can accurately identify the presence of liquid, providing a timely alarm even in the event of a trace leak. Furthermore, the electrical connection between the photoelectric probe and the circuit board ensures rapid transmission and processing of detection signals, thereby improving the response speed and accuracy of the entire detection system. Furthermore, the device also includes a detection electrode 7, which is electrically connected to the circuit board 3. Its detection end passes through the bottom shell 2 and is located below, and is used to detect leaks of conductive liquids. Because the detection electrode is used to detect leaks of conductive liquids, based on the detection results of the photoelectric probe, the water immersion detector of this embodiment can logically determine whether a conductive or non-conductive liquid is leaking in the current environment, allowing for better response.

[0037] Preferably, the bottom housing 2 is further provided with a centrally symmetrical base 8, which is provided with mounting holes 81 for fixing. This centrally symmetrical base design ensures that the water detector maintains balance during installation, avoiding tilting or shaking caused by improper installation, thereby ensuring detection accuracy and reliability. Furthermore, the mounting holes on the base not only provide a reliable support point for securing the device, but also make the installation process simpler and faster, reducing installation difficulty and cost.

[0038] Preferably, the material of the upper shell 1 is transparent PC. The transparent PC material, with its excellent transparency, high strength, heat resistance and weather resistance, brings significant advantages to the performance improvement and user experience of the water immersion detector. First, in order to be able to observe the warning issued by the LED light inside the water immersion detector, the upper shell needs to have a light-transmitting part. The transparency of the transparent PC material allows the user to intuitively observe the internal working status of the water immersion detector and the lighting of the LED light, making it easier to judge the operating status of the device and whether there are any abnormalities. This design not only improves the maintainability of the equipment, but also enhances the user's trust and satisfaction with the equipment. Secondly, the high strength and heat resistance of the transparent PC material ensure that the water immersion detector can maintain the structural integrity and stability during long-term use, and can work normally even in high temperature or humid environments, thereby extending the service life of the equipment.
