[0030] Embodiment 1

[0031] like Figure 1 As shown, a water seepage detection sensor includes: a shell 1, a controller 2, a power supply 3, a conductor component 5, and a wire 4. The shell 1 has an inner cavity, the controller 2 is installed in the inner cavity, the power supply 3 is electrically connected to the controller 2, the conductor component 5 has two conductors, the conductors are block-shaped or rod-shaped structures, the conductors are connected to the shell 1, one end of the conductors extends to the outside of the shell 1, and the wire 4 connects the conductors with the controller 2 for electrical signals.

[0032] Specifically, the controller 2 adopts an MCU processor, specifically a CiR chip from Nanjing Zhongkewei, and the MCU processor has the function of communicating with external devices in the .G frequency band; the controller 2 is installed on a PCB board, and the PCB board is connected to the protruding column in the inner cavity by bolts, and the PCB board can also be directly bonded to the shell; the power supply 3 is a battery, and the battery is installed in a battery box, and the battery box is arranged in the inner cavity. The battery box is electrically connected to the PCB board through a wire 4, and the battery box supplies power to the controller 2; the conductor adopts a conductive material, and a copper column is adopted in this embodiment, and the conductor is electrically connected to the PCB board through a wire 4.

[0033] Specifically, Figure 1 As shown, the outer side of the shell 1 has a notch, and the conductor is arranged in the notch. By arranging the conductor in the notch, the shell 1 forms a protective structure on the side of the conductor, thereby improving the anti-collision protection performance of the conductor.

[0034] Specifically, Figure 1 As shown, there are two groups of conductor components 5 which are symmetrically arranged on both sides of the housing 1 , and the sensitivity of the sensor is improved by the two groups of conductor components 5 .

[0035] Specifically, Figure 1 As shown, the housing 1 is provided with a mounting hole 101 , and the mounting hole 101 is used for inserting a screw for connection, and the housing 1 is connected to a mounting location such as a wall through the mounting hole 101 .

[0036] Taking the basement scene as an example, this water seepage detection sensor is fixed to the wall with screws. When water seeps into the wall and causes the conductor on the same side to conduct, the controller 2 receives an electrical signal and sends a signal to the outside. After receiving the signal, the external terminal device reminds the user.

[0037] By setting a hard block or rod-shaped conductor outside the shell 1 and embedding the wire 4 in the shell 1, the problem of the wire 4 being exposed and easily damaged can be avoided. At the same time, the sensor structure is simple, so the volume is relatively small, which improves the convenience of sensor installation.

[0038] Embodiment 2

[0039] Embodiment 2 further discloses on the basis of embodiment 1 that the housing 1 comprises: an upper shell and a lower shell, and the upper shell is connected to the lower shell.

[0040] Specifically, the upper shell and the lower shell can be connected by gluing or bolting, wherein the gluing method has a better sealing effect than the bolting method.

[0041] Specifically, a matching through hole is opened in the lower shell corresponding to the conductor, one end of the conductor is inserted into the through hole, and the conductor is also bonded to the lower shell at the through hole by glue, so that a sealing structure is formed between the through hole and the conductor.

[0042] Example 3

[0043] On the basis of Example 1 or 2, Example 3 further discloses that, as Figure 1 shown, the water seepage detection sensor further includes: a first seal 6, the first seal 6 is arranged between the upper housing and the lower housing, and the sealing effect of the housing 1 is improved through the first seal 6.

[0044] Specifically, as Figure 1 shown, the first seal 6 adopts a sealing strip, a first seal groove is opened on the upper edge of the lower housing, the sealing strip is inserted into the first seal groove, and when the upper housing is installed on the lower housing, the upper housing tightly presses the sealing strip.

[0045] Example 4

[0046] On the basis of Example 1, 2 or 3, Example 4 further discloses that, as Figure 1 , 2 shown, the surface of the housing 1 is provided with countersunk holes, the inner cavity is provided with support columns 102, the support columns 102 are correspondingly provided with hole bodies for the countersunk holes, the hole bodies are through holes, and the countersunk holes and the hole bodies form mounting holes 101. The mounting screws are arranged inside through the countersunk holes, reducing the exposure of the screws and reducing the influence of the screws by the external environment.

[0047] Specifically, as Figure 2 shown, the water seepage detection sensor further includes: a second seal 7, the second seal 7 is arranged at the support column 102, a circle of second seal grooves are arranged at the upper end of the support column 102, the second seal 7 adopts a sealing ring, and the sealing ring is inserted into the second seal groove to improve the sealing effect at the connection part through the second seal 7.

[0048] Specifically, as Figure 3 shown, the connection structure between the upper housing and the lower housing is similar to that at the mounting hole 101. The lower housing is provided with a connecting column 103, the connecting column 103 is provided with a threaded hole, and the bolt passes through the through hole opened on the upper housing and is threadedly connected with the threaded hole. In order to improve the sealing effect, a sealing ring is also arranged on the end face of the connecting column 103.

[0049] Example 5

[0050] As Figure 4 shown, the difference between Example 5 and Example 4 lies in that the shape of the housing 1 is different, the positions of the mounting holes 101 are different, and the connection positions between the upper housing and the lower housing are different.

[0051] As Figure 4 shown, connecting blocks 104 are arranged on both sides of the housing 1, the connecting blocks 104 are connected with a collar 8, and the inner circle of the collar 8 is the mounting hole 101. The anti-deformation ability at the connection part of the sensor is improved through the collar 8.

[0052] Specifically, as Figure 4 shown, two connecting blocks 104 are arranged on the left and right sides of the lower housing. A collar 8 is connected in the connecting block 104. The collar 8 is made of a metal material such as stainless steel or copper.
