Detailed Implementation

[0046] To make the objectives, technical solutions, and advantages of this disclosure clearer, the embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described in this disclosure can be arbitrarily combined with each other.

[0047] Please combine them together Figures 1 to 5 and Figure 7 The water immersion detector alarm provided in this disclosure embodiment will now be described. The water immersion detector alarm includes a housing assembly 10, an alarm mechanism 20, at least two first detection electrodes 30, and at least two second detection electrodes 40. The housing assembly 10 has a top surface 11 and a bottom surface 12 disposed vertically to the detection point. The top surface 11 faces away from the detection point and can receive water dripping onto the detection point. The bottom surface 12 faces the detection point and can directly face the water flowing to the detection point. In this disclosure embodiment, the housing assembly 10 includes a detachably connected first housing 13 and a second housing 14. The first housing 13 has a top surface 11, and the second housing 14 has a bottom surface 12. A sealing element 15 is provided between the first housing 13 and the second housing 14 to ensure the sealing between them. The top surface 11 has at least two first mounting holes 100, and the bottom surface 12 has at least two second mounting holes 200. In this disclosure embodiment, the number of first mounting holes 100 is two, and the number of second mounting holes 200 is four. An alarm mechanism 20 is installed within the space enclosed by the housing assembly 10. The alarm mechanism 20 includes a circuit board 21, an alarm component 22, and a power supply unit 23. The alarm component 22 is electrically connected to the circuit board 21. The power supply unit 23 is electrically connected to the circuit board 21 and is configured to supply power to at least two first detection electrodes 30, at least two second detection electrodes 40, and the alarm component 22. In this embodiment, the power supply unit 23 can be a battery. It can be understood that in other embodiments, the power supply unit 23 can also supply power to at least two first detection electrodes 30, at least two second detection electrodes 40, and the alarm component 22 via an external power source.

[0048] At least two first detection electrodes 30 are positioned and installed in at least two first mounting holes 100, and partially protrude from the top surface 11. The first detection electrodes 30 are electrically connected to the alarm mechanism 20. At least two second detection electrodes 40 are positioned and installed in at least two second mounting holes 200, and partially protrude from the bottom surface 12. The second detection electrodes 40 are electrically connected to the alarm mechanism 20. In this embodiment, the first detection electrodes 30 are positioned and installed in the first mounting holes 100, and the second detection electrodes 40 are positioned and installed in the second mounting holes 200, so that the first detection electrodes 30 and 40 can move with the first housing 13 and the second housing 14 respectively. When the first housing 13 and the second housing 14 are assembled, the first detection electrodes 30 and 40 can be positioned and installed on the circuit board 21 and electrically connected to the alarm mechanism 20. The first detection electrode 30 is configured such that the adjacent first detection electrode 30 is connected by liquid, which can trigger the alarm mechanism 20 to issue an alarm signal. The second detection electrode 40 is configured such that it is connected to the adjacent second detection electrode 30 via liquid, which can trigger the alarm mechanism 20 to issue an alarm signal. Water dripping onto the top surface 11 can also connect the adjacent first detection electrode 30, triggering the alarm mechanism 20 to issue an alarm signal. For example, the adjacent first detection electrodes 30 can be considered as the two terminals of an open circuit; water connecting the adjacent first detection electrodes 30 forms a loop, and the alarm mechanism 20 located on the loop issues an alarm signal. Similarly, water flowing to the detection point can also connect the adjacent second detection electrode 40, triggering the alarm mechanism 20 to issue an alarm signal. For example, the adjacent second detection electrodes 40 can be considered as the two terminals of an open circuit; water connecting the adjacent second detection electrodes 40 forms a loop, and the alarm mechanism 20 located on the loop issues an alarm signal. In this embodiment, the alarm component 22 includes a buzzer 221 and a light-emitting unit 222. The alarm signal emitted by the alarm mechanism 20 can be an audible signal emitted by the buzzer 221, an optical signal emitted by the light-emitting unit 222, or a combination of the audible signal emitted by the buzzer 221 and the optical signal emitted by the light-emitting unit 222.

[0049] The water immersion detector alarm described above includes a housing assembly 10, an alarm mechanism 20, at least two first detection electrodes 30, and at least two second detection electrodes 40. The housing assembly 10 has a top surface 11 and a bottom surface 12 perpendicular to the detection point. By placing at least two first detection electrodes 30 on the top surface 11, water dripping onto the top surface 11 can be detected. When adjacent first detection electrodes 30 are connected by liquid, the alarm mechanism 20 is triggered to issue an alarm signal. Similarly, by placing at least two second detection electrodes 40 on the bottom surface 12, water (ground immersion) at the detection point can be detected. When adjacent second detection electrodes 40 are connected by liquid, the alarm mechanism 20 is triggered to issue an alarm signal. This allows the water immersion detector alarm to simultaneously detect both ground immersion and dripping water scenarios, avoiding the need to deploy multiple types of water immersion detector alarms at the same detection point, thereby reducing detection costs.

[0050] In the exemplary embodiments, please refer to Figure 2 , Figure 3 , Figure 9 and Figure 10 At least two first elastic conductive portions 50 are provided on the side of the circuit board 21 facing the top surface 11. At least two first detection electrodes 30 elastically abut against the at least two first elastic conductive portions 50 respectively, so as to be electrically connected to the circuit board 21. In this way, the elastic abutment between the first detection electrodes 30 and the first elastic conductive portions 50 can ensure the connection stability between the first detection electrodes 30 and the first elastic conductive portions 50, thereby ensuring the stability of the electrical connection. In addition, it can also play a certain buffering role, so that the connection stability between the first detection electrodes 30 and the first elastic conductive portions 50 can still be maintained when the housing assembly 10 undergoes a small deformation. Furthermore, when the first detection electrodes 30 are installed on the circuit board 21 along with the first housing 13, the first elastic conductive portions 50 can play a buffering role, avoiding excessive impact from the first detection electrodes 30 on the circuit board 21, which could cause damage to the circuit board 21.

[0051] At least two second elastic conductive portions 60 are provided on the side of the circuit board 21 facing the bottom surface 12. At least two second detection electrodes 40 elastically abut against each of the at least two second elastic conductive portions 60 to achieve electrical connection with the circuit board 21. This elastic abutment between the second detection electrodes 40 and the second elastic conductive portions 60 ensures the stability of the connection, thereby guaranteeing the stability of the electrical connection. Furthermore, it provides a certain buffering effect, ensuring the connection stability between the second detection electrodes 40 and the second elastic conductive portions 60 even when the housing assembly 10 undergoes slight deformation. Moreover, when the second detection electrodes 40 are mounted on the circuit board 21 along with the second housing 14, the second elastic conductive portions 60 provide a buffering effect, preventing excessive impact from the second detection electrodes 40 on the circuit board 21 and thus avoiding damage to the circuit board 21.

[0052] In an exemplary embodiment, such as Figure 10 As shown, the first elastic conductive part 50 includes a first base 51 and a first elastic arm 52. The first base 51 is fixed to the circuit board 21. The first base 51 can be fixedly connected to the circuit board 21 by welding or bonding, and is electrically conductive. The first base 51 is provided with a first guide groove 300 facing the first detection electrode 30. One end of the first elastic arm 52 is disposed on the first base 51, and the other end has a first bending part 521. The first bending part 521 is movably installed in the first guide groove 300 and partially protrudes outward from the side of the first base 51 facing the first detection electrode 30. In this way, the first guide groove 300 can improve the accuracy of the elastic deformation direction of the first elastic arm 52 and ensure the accuracy of the elastic contact between the first bending part 521 and the first detection electrode 30. The first bending portion 521 has a first bending space 400 away from the first detection electrode 30, so that the side of the first bending portion 521 facing the first detection electrode 30 is an arc surface, reducing wear on the first detection electrode 30, and allowing the first bending portion 521 to slide relative to the first detection electrode 30 to adjust the position of the first elastic arm 52 relative to the first detection electrode 30, and avoid plastic deformation of the first elastic arm 52.

[0053] In the exemplary embodiments, please continue to refer to Figure 10A first folding portion 53 is provided between the first base 51 and the first elastic arm 52. This reduces the angle between the first base 51 and the first elastic arm 52 under the abutment of the first detection electrode 30, preventing plastic deformation between them and reducing the elastic abutment effect. The first base 51 and the first folding portion 53 are connected by a second bending portion 54, which has a second bending space 500 on the side facing the circuit board 21. This second bending portion 54 enhances the strength of the first elastic conductive portion 50 and ensures the stability of the elastic deformation of the first elastic arm 52.

[0054] In an exemplary embodiment, such as Figure 10 As shown, the first elastic conductive part 50 and the second elastic conductive part 60 have the same structure. The second elastic conductive part 60 includes a second base 61 and a second elastic arm 62. The second base 61 is fixed to the circuit board 21. The second base 61 can be fixedly connected to the circuit board 21 by welding or bonding, and is electrically conductive. The second base 61 is provided with a second guide groove facing the second detection electrode 40. One end of the second elastic arm 62 is disposed on the second base 61, and the other end has a third bend. The third bend is movably installed in the second guide groove and partially protrudes outward from the side of the second base 61 facing the second detection electrode 40. In this way, the setting of the second guide groove can improve the accuracy of the elastic deformation direction of the second elastic arm 62 and ensure the accuracy of the elastic contact between the third bend and the second detection electrode 40. The third bend has a third bend space away from the second detection electrode 40, so that the side of the third bend facing the second detection electrode 40 is an arc surface, reducing wear on the second detection electrode 40, and allowing the third bend to slide relative to the second detection electrode 40 to adjust the position of the second elastic arm 62 relative to the second detection electrode 40, thus preventing the second elastic arm 62 from undergoing plastic deformation.

[0055] In the exemplary embodiments, please continue to refer to Figure 10 A second fold is provided between the second base 61 and the second elastic arm 62. This reduces the angle between the second base 61 and the second elastic arm 62 under the contact action of the second detection electrode 40, preventing plastic deformation between the second base 61 and the second elastic arm 62 and reducing the elastic contact effect between the second elastic arm 62 and the second detection electrode 40. The second base 61 and the second fold are connected by a fourth bend, which has a fourth bend space on the side facing the circuit board 21. This fourth bend enhances the strength of the second elastic conductive part 60 and ensures the elastic deformation stability of the first elastic arm 52.

[0056] In the exemplary embodiments, please refer to Figures 1 to 6The top surface 11 has a groove 600 recessed towards the bottom surface 12. The first mounting hole 100 is connected to the side of the groove 600 near the bottom surface 12. Thus, the groove 600 can collect water dripping onto the top surface 11, making the first detection electrode 30 more accurate in detecting water.

[0057] In an exemplary embodiment, please refer to 2 and Figure 6 The first mounting hole 100 penetrates the housing assembly 10 and includes a first hole segment 101 and a second hole segment 102. The first hole segment 101 is exposed on the top surface 11. In this embodiment, the first hole segment 101 communicates with the groove 600. The housing assembly 10 is provided with a first annular wall 16, which is coaxially arranged with and housed in the second hole segment 102. The first detection electrode 30 includes a body 31 and a head end 32. The body 31 is electrically connected to the alarm mechanism 20 and is provided with a first annular groove that matches the first annular wall 16. The body 31 is snapped and sealed with the first annular wall 16 through the first annular groove, and the head end 32 is placed in the first hole segment 101, with a portion of the head end 32 protruding outward from the top surface 11. In this way, the first annular wall 16 and the first annular groove can achieve a snap-fit ​​seal between the body 31 and the housing assembly 10, ensuring the connection stability of the first detection electrode 30 and the housing assembly 10, and ensuring sealing to prevent water from flowing into the housing assembly 10 from the first mounting hole 100.

[0058] In the exemplary embodiments, please refer to Figures 2 to 4 , Figure 7 and Figure 8 The bottom surface 12 has multiple support columns 17 supporting the detection point, which can suspend the second detection electrode 40 at the detection point. In this embodiment, there are four support columns 17, which are arranged near the four corners of the bottom surface 12 to ensure the stability of the water immersion detector at the detection point and to prevent the second detection electrode 40 from directly contacting the detection point (e.g., the ground) to avoid wear and affect the detection effect.

[0059] In an exemplary embodiment, such as Figure 3 As shown, the second mounting hole 200 penetrates the housing assembly 10. The housing assembly 10 is provided with a second annular wall 18, which is coaxially arranged with and housed within the second mounting hole 200. The second detection electrode 40 is provided with a second annular groove that matches the second annular wall 18. The second detection electrode 40 is engaged and sealed with the second annular wall 18 through the second annular groove. This arrangement of the second annular wall 18 and the second annular groove ensures a secure connection between the second detection electrode 40 and the housing assembly 10, guaranteeing connection stability and sealing to prevent water from flowing into the housing assembly 10 through the second mounting hole 200.

[0060] In the exemplary embodiments, please refer to Figure 1 , Figures 3 to 6 , Figure 8 and Figure 9 The water immersion detector also includes a cover 70, which has a snap-fit ​​part 71 and a plug-in part 72. The top surface 11 has a sound hole 700, a snap-fit ​​groove 800, a plug-in groove 900, and a light-transmitting hole 1000. The snap-fit ​​part 71 snaps into the snap-fit ​​groove 800, and the plug-in part 72 plugs into the plug-in groove 900, thus covering the sound hole 700. In this way, the cover 70 can be positioned with the housing assembly 10 first by the plug-in part 72 engaging with the plug-in groove 900, and then snapped into place by the snap-fit ​​part 71 and the snap-fit ​​groove 800, thereby securing the cover 70 to the housing assembly 10 and covering the sound hole 700 to prevent external impurities from falling into it. A buzzer 221 is disposed within the space enclosed by the housing assembly 10 and faces the sound hole 700. A light-emitting unit 222 faces the light-transmitting hole 1000. The water immersion alarm also includes a light-transmitting element 80, which is placed between the light-transmitting hole 1000 and the light-emitting unit 222, sealing the light-transmitting hole 1000. The light-transmitting element 80 guides the light emitted by the light-emitting unit 222 to the light-transmitting hole 1000 and ensures the sealing of the light-transmitting hole 1000. Furthermore, the water immersion alarm may also include a button 90, capable of resetting or closing the alarm mechanism 20 to stop emitting alarm signals to the outside world. In this embodiment, the button 90 includes a pressing portion 91 exposed in the groove 600, a sealing portion 92, and a control unit 93 electrically connected to the circuit board 21. The top surface 11 is provided with a mounting groove 1100 communicating with the groove 600. The pressing part 91 seals the end of the mounting groove 1100 facing the recess 600, and the sealing part 92 seals the end of the mounting groove 1100 near the circuit board 21. Both the pressing part 91 and the sealing part 92 are made of rubber. The pressing part 91 can trigger the control unit 93 through the sealing part 92, thereby resetting or turning off the alarm mechanism 20.
