[0068] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0069] This embodiment provides a water leakage detector. Figures 1-11 This is a schematic diagram provided for this embodiment.

[0070] like Figures 1-3 The leak detector 1000 includes a detection component 200 and a mounting base 100. The detection component 200 is used for leak detection, and the mounting base 100 is used for mounting the detection component 200. The structure of the detection component 200 is shown below. Figures 4-5 The structure of mounting base 100 is shown in the figure. Figures 6-11 .

[0071] like Figure 6 , Figure 7 The mounting base 100 includes a back plate 111, a baffle plate 112, and a support column 121. The width direction of the back plate 111 is the W direction, the thickness direction is the T direction, and the height direction is the H direction. The detection component 200 is disposed at one end of the back plate 111 along the T direction, such as... Figure 2 , Figure 3 , Figure 6 , Figure 7 In this embodiment, the detection component 200 is disposed in front of the back plate 111. The water baffle 112 is disposed above the detection component 200, and the projection of the water baffle 112 along the H direction covers the detection component 200, so that the water baffle 112 forms a cover above the detection component 200, which can prevent water from dripping down from above the detection component 200 and leaking to the detection component 200, causing the water leak detector 1000 to falsely alarm, thereby improving the reliability of the operation of the water leak detector 1000. The support column 121 is disposed between the back plate 111 and the surfaces of the detection component 200 facing each other along the T direction, and protrudes outward from the surface of the back plate 111 facing the detection component 200. In this embodiment, the support column 121 protrudes outward from the front of the back plate 111, providing support for the detection component 200, so that there is a gap between the surfaces of the detection component 200 and the back plate 111 facing each other. This can prevent water from flowing along the front of the back plate 111 to the detection component 200 and causing false alarms from the leak detector 1000, thereby improving the reliability of the leak detector 1000.

[0072] In a preferred embodiment, such as Figure 6 , Figure 7The baffle plate 112 and the back plate 111 are integrally formed to create a sealed connection. This improves the coverage of the detection component 200 by the baffle plate 112, further reducing the risk of water dripping from above the detection component 200 and causing false alarms by the leak detector 1000, thus improving the reliability of the leak detector 1000. The integral forming of the baffle plate 112 and the back plate 111 ensures a simple and reliable seal. In other embodiments, the baffle plate 112 and the back plate 111 can be sealed by bonding, using a sealing ring, or other methods.

[0073] like Figures 3-4 , Figure 4 In this embodiment, there are four support columns 121. The four support columns 121 are distributed at intervals along the H and W directions, which can provide multi-point support for the detection component 200 along the H and W directions, improve the support effect of the support columns 121 on the detection component 200, further reduce the risk of water flowing along the back plate 111 towards the surface of the detection component 200 and causing false alarms by the leak detector 1000, thereby further improving the reliability of the leak detector 1000.

[0074] like Figure 4 The detection component 200 includes two spaced-apart conductors 210, a first conductor 211 and a second conductor 212. When water leaks, the leak detector 1000 can detect the leak signal when water conducts through the two conductors 210. In a preferred embodiment, the detection component 200 includes an insulator 230, with the two conductors 210 disposed at both ends of the insulator 230 along the T direction, separating the two conductors 210. Even if there are small amounts of water droplets or moisture at the detection component 200, the two conductors 210 will not be connected, avoiding the possibility of false alarms by the leak detector 1000 and improving the reliability of the leak detector 1000. In this embodiment, the first conductor 211 is disposed in front of the insulator 230, and the second conductor 212 is disposed behind the insulator 230. Figure 4 To detect the rear view of component 200, Figure 4 The position of the first conductor 211 is indicated by a dashed line. In fact, the first conductor 211 is not visible behind the insulator 230.

[0075] Specifically, in the embodiment, the detection assembly 200 further comprises two conductive poles 220, a first conductive pole 221 and a second conductive pole 222, the first conductive body 211 is electrically connected to one wire 300 through the first conductive pole 221, and the second conductive body 212 is electrically connected to another wire 300 through the second conductive pole 222, and signals conducted by the first conductive body 211 and the second conductive body 212 are transmitted out through the two wires 300. In a preferred embodiment, the second conductive pole 222 and the second conductive body 212 can be arranged on the same side of the insulator 230 to facilitate electrical connection between the two. The detection assembly 200 can adopt a printed circuit board (PCB), and the two conductive bodies 210 and the two conductive poles 220 can be printed on the board of the PCB.

[0076] In other embodiments, the first conductive body 211 and the second conductive body 212 can be arranged on the same side of the insulator 230 to simplify the structure of the water leakage detector 1000. In other embodiments, the insulator 230 can be omitted, and the first conductive body 211 and the second conductive body 212 can be arranged on the mounting base 100 to simplify the structure of the water leakage detector 1000.

[0077] In a preferred embodiment, as shown in Figure 6 , the two conductive bodies 210 are arranged along the W direction, which can further avoid false positives caused by water vapor, a small amount of water droplets, etc. In a preferred embodiment, as shown in Figure 7 , the two conductive bodies 210 are located above the lower edge of the insulator 230 along the H direction, and are spaced apart from the lower edge of the insulator 230 by a certain distance, preferably 2 mm. This can further verify the authenticity of the water leakage, and only when the amount of water leakage is large will an alarm be triggered. If there is only a few drops of water, it is considered to be water vapor or moisture, and no alarm will be triggered, thereby further reducing the possibility of false positives of the two conductive bodies 210.

[0078] As shown in Figure 2 , Figure 3 , the mounting base 100 has a water inlet 115, and the water inlet 115 penetrates the mounting base 100 along the T direction. As shown in Figure 6 , Figure 7 , Figure 2 , Figure 3 , the water inlet 115 is connected to the two conductive bodies 210, and when water flows to the water inlet 115 and the water level reaches the height of the two conductive bodies 210, the water can conduct the two conductive bodies 210, so that the water leakage detector 1000 can detect the water leakage signal. Further, the range of the water inlet 115 along the W direction covers the range of the two conductive bodies 210 along the W direction, so that the water can flow from the water inlet 115 to the two conductive bodies 210 to conduct the two conductive bodies 210, thereby improving the sensitivity of the water leakage detector 1000 in detecting water leakage. Specifically, the water inlet 115 is rectangular in shape, which is simple in structure and convenient to process.

[0079] As Figure 6 , Figure 7 , Figure 2 , Figure 3 The mounting seat 100 further comprises a bottom plate 113 arranged below the detection assembly 200. On the one hand, the mounting seat 100 is installed at the installation position through the bottom plate 113. On the other hand, the bottom plate 113 can raise the height of the detection assembly 200. Even if a small amount of condensed water remains at the bottom, it will not cause the detection assembly 200 to detect a water leakage signal, and the reliability of preventing false positives can be prevented.

[0080] As Figure 6 , Figure 7 , Figure 2 , Figure 3 The mounting seat 100 further comprises two side plates 114, the bottom plate 113 and the two side plates 114 are extended from the back plate 111 along the T direction away from the end of the back plate 111 away from the detection assembly 200, the two side plates 114 are connected to the two ends of the back plate 111 in the W direction, and the bottom plate 113 is connected below the two side plates 114. The bottom plate 113 and the back plate 111 are connected together through the side plate 114, and the side plate 114 can improve the structural strength and stability after installation of the mounting seat 100, thereby improving the reliability of the water leakage detector 1000. In particular, the side plate 114 in the embodiment is trapezoidal, close to triangular, which can act as a reinforcing rib to support the back plate 111 and prevent the back plate 111 from breaking when subjected to external force.

[0081] In a preferred embodiment, as Figure 6 , Figure 7 , Figure 4 , Figure 5 The mounting seat 100 further comprises an installation limiting piece 131 arranged at one end of the back plate 111 along the T direction towards the detection assembly 200, the installation limiting piece 131 deviates from the center of the back plate 111 along the W direction and the center along the H direction. In the embodiment, the installation limiting piece 131 is specifically arranged at the upper right part of the back plate 111, as Figure 2 , Figure 3 The detection assembly 200 is provided with an installation matching part 231, and the installation limiting piece 131 and the installation matching part 231 are concave-convex matched. When the detection assembly 200 is installed on the mounting seat 100, it can prevent the detection assembly 200 from being installed in reverse, and improve the accuracy and convenience of assembly. In particular, in the embodiment, the installation matching part 231 is arranged on the insulating piece and is a through hole, and the installation limiting piece 131 is a convex column.

[0082] In a preferred embodiment, as Figure 6 , Figure 7 , Figure 2 , Figure 3The mounting seat 100 further comprises two side limiting members 134 which are arranged on the front surface of the back plate 111 and protrude outwardly from the back plate 111. The two side limiting members 134 are respectively arranged at the two ends of the back plate 111 along the W direction. The detection assembly 200 is arranged between the two side limiting members 134. The two side limiting members 134 can respectively limit the two ends of the detection assembly 200, thereby improving the reliability of the installation of the detection assembly 200 on the mounting seat 100.

[0083] In a preferred embodiment, as Figure 6 , Figure 7 , Figure 8 , Figure 2 The mounting seat 100 further comprises a bottom limiting member which is in the shape of an L with an opening upwardly facing the detection assembly 200. Part of the detection assembly 200 is arranged in the opening of the bottom limiting member. The L-shaped bottom limiting member can limit the front and lower sides of the detection assembly 200, thereby improving the reliability of the installation of the detection assembly 200 on the mounting seat 100. Further, the bottom limiting member is in the shape of an L, and the opening of the bottom limiting member faces and communicates with the water inlet 115. When water leaks, the water can enter the opening of the bottom limiting member from the side of the bottom limiting member or the water inlet 115 to flow to the detection assembly 200, so that the detection assembly 200 can detect the water leakage signal. The detailed structure of the bottom limiting member can be seen from Figure 3 .

[0084] In a preferred embodiment, as Figure 6 , Figure 7 , Figure 9 , Figure 10 The mounting seat 100 further comprises a top limiting member 132 which is in the shape of an L with an opening downwardly facing the detection assembly 200. Part of the detection assembly 200 is arranged in the opening of the top limiting member 132. The top limiting member 132 is connected to the back plate 111 by a deformable connecting plate 141 which has a thickness smaller than that of the top limiting member 132. The L-shaped top limiting member 132 can limit the upper and front sides of the detection assembly 200, thereby improving the reliability of the installation of the detection assembly 200 on the mounting seat 100. As Figure 9 , Figure 6 The top limiting member 132 is connected to the water baffle 112 by the deformable connecting plate 141, so that the top limiting member 132 forms a buckle structure. The detection assembly 200 can be taken out of the opening of the top limiting member 132 by deforming the connecting plate 141. The thickness of the connecting plate 141 is smaller than that of the top limiting member 132, so that the connecting plate 141 is more easily deformed relative to the top limiting member 132 under stress. A reinforcing plate 142 is arranged at the end of the top limiting member 132 along the T direction which is close to the back plate 111, so as to improve the strength of the top limiting member 132 and further make the connecting plate 141 more easily deformed relative to the top limiting member 132. Figure 7The approximate boundary of the connecting plate 141 is shown by a dashed line.

[0085] In a preferred embodiment, the top limiting member 132 and the bottom limiting member are provided simultaneously, and the detection assembly 200 can be taken out from the opening of the bottom limiting member in the direction of the top limiting member 132 by deforming the connecting plate 141.

[0086] As Figure 7 , Figure 11 In the embodiment, the number of the bottom limiting member and the top limiting member 132 is two respectively, and they are arranged at the two ends of the back plate 111 along the W direction respectively.

[0087] In the embodiment, the back plate 111, the water baffle 112, the bottom plate 113, the side plate 114, the mounting limiting member 131, the side limiting member 134, the bottom limiting member, the top limiting member 132, the connecting plate 141, and the reinforcing plate 142 are integrally formed by pouring, so that the connection of the parts of the mounting seat 100 is convenient and the connection strength is high.

Specifically, the magnet 122 is arranged at one end of the bottom plate 113 away from the detection assembly 200 along the H direction.

[0091] As ​ The bottom plate 113 is provided with a magnet mounting hole 1131, specifically a groove, and the inner wall of the magnet mounting hole 1131 is provided with a plurality of convex strips 1132, the plurality of convex strips 1132 are distributed at intervals around the axis of the magnet mounting hole 1131, and the magnet 122 is arranged in the magnet mounting hole 1131 and is clamped by the plurality of convex strips 1132 in the magnet mounting hole 1131. The number of the magnet 122 and the magnet mounting hole 1131 is arranged in pairs, which can improve the reliability of the water leakage detector 1000 installed in the installation position. In order to show the structure of the magnet mounting hole 1131 and the convex strip 1132, ​ One magnet 122 is omitted in the figure.
