Description

Technical Field

[0001] This disclosure relates to the field of water immersion sensor technology, and more particularly to a water immersion line, a water immersion sensor body, and a water immersion sensor. Background Technology

[0002] Currently, the mainstream water immersion sensor on the market is a water immersion sensor with a water immersion line. One end of the water immersion line is connected to a probe, which has a probe. This results in a very small detection area, limiting its applications. Figure 1 As shown.

[0003] The main body of the water immersion sensor consists of an external plastic shell and a silicone ring, and an internal functional PCB and button battery. The water immersion circuit includes a rubber wire with two metal probes at the end that conduct water to trigger an alarm. Battery replacement for water immersion sensors: Many products on the market require tools to unscrew the coin slot on the bottom shell to open and replace the battery. Figure 2 As shown.

[0004] Currently, water immersion sensors have the following drawbacks:

[0005] 1. The surface of the water immersion line is covered with rubber to isolate it from water. An alarm is only triggered when the two probes at the tail come into contact with water. Since the two probes contact the water through metal points, the detection area is too small. An alarm is only triggered when the water reaches the probe feet, often resulting in a missed alarm opportunity.

[0006] 2. The water immersion line is fixedly connected to the main electrode of the water immersion sensor, and cannot be freely disassembled or extended, resulting in a very small application area and limited applicable occasions.

[0007] 3. Battery replacement method for water immersion sensor: The bottom cover needs to be unscrewed with tools. Utility Model Content

[0008] The purpose of this disclosure is to provide a water immersion line, a water immersion sensor body, and a water immersion sensor, thereby solving the aforementioned problems existing in the prior art.

[0014] For example, the second end includes a connector for inserting into a slot within the connector of another water immersion line.

[0015] Another aspect of this disclosure provides a water immersion sensor body for use in conjunction with the water immersion line as described above.

[0016] For example, two mounting holes are symmetrically arranged radially in the central area of ​​the bottom wall of the mounting cavity. The mounting holes are circumferentially provided with groove walls extending outward by a preset distance. The groove walls form a limiting groove. An annular mounting plate is provided at the end of the limiting groove. A shell cover is provided at the second end of the water immersion line.

[0047] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the embodiments of this disclosure will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the embodiments of this disclosure and are not intended to limit the embodiments of this disclosure.

[0048] like Figures 3 to 6 As shown, one embodiment of this disclosure proposes a water immersion wire for use in a water immersion sensor. The water immersion wire 300 includes: a water immersion wire body 310, the outer sheath of which is covered with a water-permeable material; a first end 320 disposed at one end of the water immersion wire body 310, the first end 320 having a water immersion wire main board 340 inside and a connecting portion on its side wall, the first end 320 being detachably electrically connected to a water immersion sensor body 400; and a second end 330 disposed at the other end of the water immersion wire body 310, the second end 330 being detachably connected to the connecting portion of the first end 320 of another water immersion wire 300.

[0049] The connecting portion 322 of this embodiment is electrically connected to the main board 340 of the water immersion line. The connecting portion can be disposed inside the first end 320, outside the first end 320, or spanning both the inner and outer sides of the first end 320, depending on the actual situation. Compared with traditional rubber-coated water immersion lines, the water immersion line of this embodiment improves the outer material from rubber to a water-permeable material, such as braided thread. The improved water immersion line will sense a signal when it comes into contact with water and reaches a certain humidity level, and transmit it to the main board to issue an alarm. The contact has been expanded from point contact of the probe pins to surface contact of the braided thread, realizing timely alarm and expanding the detection range.

[0050] Moreover, compared to the existing method of fixing one end of the water immersion wire to the main electrode of the water immersion sensor, the water immersion wire of this embodiment is detachably connected to the main electrode of the water immersion sensor, and multiple water immersion wires can be connected in series through two ends, infinitely expanding the detection area. In addition to being suitable for small-scale water immersion alarms in homes, it also enables long-distance water pipe leakage early warning and large warehouse water accumulation early warning.

[0051] like Figures 7 to 9As shown, as a specific example of the first end, the first end 320 includes: a housing 321 having an open receiving cavity 3211, the receiving cavity 3211 having opposing connection ports 3212 and mounting ports 3213 on its sidewalls; the receiving cavity 3211 having the water immersion line main board 340 on its bottom wall; a connecting part 322 having a slot 3221, the connecting part 322 being disposed on the water immersion line main board 340 and electrically connected to the water immersion line main board 340, the slot 3221 being connected to the connection port 3212; and a cover 323 detachably covering the open, the cover 323 having two through holes 3231 symmetrically arranged radially on its surface.

[0052] The slot in this embodiment of the present disclosure is provided with a tongue, and the second end is provided with a plug-in end that matches the slot. For example... Figure 8 As shown, in this embodiment of the present disclosure, the accommodating cavity 3211 can be provided with a plurality of reinforcing ribs 3216 circumferentially on the side wall. The reinforcing ribs 3216 are provided with mounting platforms 3217 near the edge of the central area. The bottom wall of the accommodating cavity 3211 is provided with mounting ribs along the diameter. The two ends of the mounting ribs are respectively connected to reinforcing ribs. The central area of ​​the mounting ribs is provided with mounting posts (not shown in the figure). The mounting posts are provided with threads. The central area of ​​the water immersion line main board 340 is provided with mounting holes (not shown in the figure). The water immersion line main board 340 is disposed on the mounting platform 3217 and is fastened to the bottom of the housing 321 by bolts passing through the mounting holes and mounting posts. The mounting port 3213 and the connecting port 3212 are respectively provided with reinforcing ribs 3216 on both sides. Each reinforcing rib 3216 is provided with a mounting step 3218 that is recessed towards the bottom wall of the receiving cavity 3211 near the side wall of the receiving cavity 3211. When a U-shaped spring piece 325 is installed in the receiving cavity 3211, the reinforcing ribs 3216 at both ends of the mounting ribs are also respectively provided in the central area of ​​the top wall of the U-shaped spring piece 325, and in contact with the top wall of the U-shaped spring piece 325. The water immersion line main board 340 is provided with a recessed groove at the edge of the U-shaped spring piece, and the corresponding reinforcing rib passes through the groove at the edge of the water immersion line main board 340.

[0053] The accommodating cavity 3211 has multiple inwardly protruding second latching protrusions 3220 circumferentially arranged on its sidewall. The outer sidewall of the cover 323 has grooves 3233 that mate with the second latching protrusions 3220, and multiple notches 3232 that mate with the corresponding reinforcing ribs 3216. The sidewall of the cover 323 also has limiting grooves that mate with the connecting part 322 and the fixing member 311. The inner sidewall of the housing 321 has a limiting step 3219 circumferentially arranged near the edge of the opening, and the mounting step 3218 is lower than the limiting step 3219. The end of the sidewall of the cover 323 is circumferentially recessed inward, forming an engaging step near its bottom (surface) that mates with the limiting step 3219. The notches 3232 engage with the reinforcing ribs, and the bottom of the notches is located on the mounting step 3218. The cover 323 covers the opening of the housing 321, and the second protrusion 3220 cooperates with the groove 3233 to realize the detachable installation of the cover 323 and the housing 321. The limiting step cooperates with the engaging step so that the surface of the cover is flush with the edge of the housing.

[0054] Besides material improvements, the water-immersed cable's functionality has also been enhanced. The cable's head is secured with a rubber shell; the outer casing of the first end is made of rubber, and inside the shell is a water-immersed PCB board, the main board of the water-immersed cable. A Type-C female connector, the connection part, is soldered onto the main board. The tail end of the water-immersed cable has a Type-C male connector, the second end, which is used to connect to a slot in the connection part of another water-immersed cable. This design allows multiple water-immersed cables to be connected in series using the Type-C male and female connectors, infinitely expanding the detection area. The specific structure of the connection part and the second end (Type-C female and Type-C male connectors) can be customized according to actual needs.

[0055] like Figure 7 and Figure 8 As shown, as a specific example of the first end, the first end 320 further includes: a first magnetic suction member 324, disposed in the central area of ​​the cover 323; two U-shaped spring pieces 325, the two U-shaped spring pieces 325 being disposed on both sides of the first magnetic suction member 324, and any one foot of the two U-shaped spring pieces 325 being fixed to the water immersion line main board 340 and electrically connected to the water immersion line main board 340; when the cover 323 is placed on the housing 321, the through hole 3231 corresponds to the top plate of the corresponding U-shaped spring piece 325.

[0056] The first magnetic component in this embodiment can be either a magnet or a magnetic strip. Two water-immersion springs, specifically U-shaped springs, are soldered onto the water immersion cable motherboard. One leg of the U-shaped spring is threaded through and soldered to the water immersion cable motherboard PCB, while the other leg is threaded through the PCB but not soldered, allowing the U-shaped spring to spring up elastically. The water immersion sensor body contains either a magnet or a magnetic strip, as well as two probe pins; the specific structure is described later. The first magnetic component and the U-shaped springs are mainly used to achieve a detachable connection with the water immersion sensor body and a conductive connection between the water immersion cable motherboard and the water immersion sensor motherboard. The central area of ​​the cover has a receiving groove for the first magnetic component and a receiving groove for the top plate of the U-shaped springs. The Type-C female connector, water immersion cable, and two springs are soldered to the water immersion cable PCB. The PCB is secured to the water immersion faceplate (i.e., the housing) using screws. The magnet is fixed to the bottom shell (i.e., the cover) by adhesive. The water immersion faceplate (i.e., the bottom shell) is secured by four clips.

[0057] like Figure 8 As shown, as a specific example of the housing, the receiving cavity 3211 is provided with a limiting part 3214 near the mounting port 3213, and the limiting part 3214 is provided with a slot 3215 in the central area; one end of the water immersion line body 310 is provided with a fixing member 311, and the fixing member 311 is provided with a first circumferentially protruding protrusion 312 near the end; the fixing member 311 passes through the mounting port 3213 and is provided with the limiting part 3214, and the first protrusion 312 is provided with the slot 3215; the wire core at one end of the water immersion line body 310 has two branch wires, both of which extend out of the fixing member 311 and are electrically connected to the water immersion line main board 340 respectively.

[0058] It should be noted that the ends of the reinforcing ribs on both sides of the mounting port 3213 are provided with the limiting part 3214. The end face of the limiting part 3214 is provided with a groove that matches the fixing member. The central area of ​​the limiting part is provided with a slot 3215 that cooperates with the first protrusion of the fixing member. The cover is provided with a limiting groove corresponding to the limiting part. After the cover is closed on the housing, the limiting part and the limiting groove can just accommodate the second end.

[0059] like Figure 10 and Figure 12As shown, another aspect of this disclosure provides a water immersion sensor body for use in conjunction with the aforementioned water immersion line. The water immersion sensor body 400 includes: a housing 410 with an open mounting cavity 411, the housing 410 being detachably connected to the first end 320 of the water immersion line 300; a battery assembly 430, which includes a water immersion sensor main board (420) and a battery (432), the battery assembly (430) being detachably disposed in the mounting cavity 411, and the water immersion sensor main board (420) being detachably electrically connected to the water immersion sensor main board 420; and a housing cover 440, which is detachably and sealingly disposed in the opening.

[0060] The water immersion sensor body and the first end of the water immersion wire can be flexibly disassembled and assembled, and the two can be arbitrarily combined to form a water immersion sensor. The water immersion wire can also be connected in series indefinitely to expand the sensing range of the water immersion sensor. There is a water immersion sensor motherboard (420) and a battery (432) electrically connected, and the battery assembly 430 supplies power to the water immersion sensor motherboard 420.

[0061] like Figure 10 and Figure 11 As shown, as a specific example of the water immersion sensor body, the mounting cavity 411 has two mounting holes (not shown in the figure) arranged radially symmetrically in the central area of ​​the bottom wall. The mounting holes are provided with groove walls circumferentially extending outward by a preset distance. The groove walls form a limiting groove 4111. An annular mounting plate is provided at the end of the limiting groove (4111). The second end 330 of the water immersion line 300 is provided with a cover 323. When the cover 323 is provided with a through hole 3231, the mounting hole corresponds to the corresponding through hole 3231.

[0062] like Figure 11 As shown, the water immersion sensor body 400 further includes: two probes 450, respectively disposed in corresponding mounting holes, one end of each probe 450 passing through the corresponding mounting hole, one end of each probe 450 being used for electrical connection with the water immersion line main board 340, a retaining platform being provided around the probe, one end face of the retaining platform engaging with the bottom surface of the limiting groove, the other end face of the retaining platform being spaced from the annular mounting plate, the other end of the probe 450 passing through the annular mounting plate for electrical connection with the water immersion sensor main board 420; and two elastic members 460, respectively disposed in corresponding limiting grooves 4111, one end abutting against the other end face of the retaining platform, and the other end abutting against the annular mounting plate.

[0063] In this embodiment of the present disclosure, when the water immersion sensor body and the water immersion line are not assembled, the elastic element pushes one end of the probe out of the mounting hole, and the other end of the probe has a gap with the main board of the water immersion sensor. When the water immersion sensor body and the water immersion line are assembled, the probe moves downward, compressing the elastic element, and the other end of the probe is electrically connected to the main board of the water immersion sensor, thus realizing the electrical connection between the water immersion line and the water immersion sensor body. The elastic element can be a spring.

[0064] like Figure 12 As shown, as a specific example of a battery assembly, the battery assembly 430 includes: a battery mounting member 431 having a spacer plate, with a first slot and a second slot on each side of the spacer plate, the first slot being provided with the battery and the second slot being provided with the water immersion sensor main board (420); a metal spring is provided in the central area of ​​the spacer plate to electrically connect the battery and the water immersion sensor main board; the battery mounting member 431 is detachably disposed in the mounting cavity 411, with the second slot facing the bottom of the mounting cavity (411); and a battery cover plate 433 covering the surface of the battery 432 and engaging with the side wall of the battery slot.

[0065] Specifically, such as Figures 15 to 19 As shown, each mounting hole on the bottom wall of the mounting cavity of the outer casing is provided with a bolt post 413. Multiple snap-fit ​​pre-positions 412 are circumferentially arranged on the side wall of the outer casing, with the snap-fit ​​pre-positions 412 located near the opening; specifically, there are four snap-fit ​​pre-positions, each a protruding structure. Multiple engaging and fixing positions 4311 are circumferentially arranged on the side wall of the battery mounting component, with the snap-fit ​​pre-positions 412 matching the engaging and fixing positions 4311. The engaging and fixing positions are located near the first slot and are recessed groove structures. Bolt holes 4313 are symmetrically arranged radially near the edge of the battery mounting component. The battery mounting component is securely connected to the bottom wall of the outer casing via bolts, bolt holes, and corresponding bolt posts. The second slot is provided with a limiting rib and a limiting buckle 4312. The water immersion sensor mainboard is located in the second slot, and the limiting buckle engages with the surface of the water immersion sensor mainboard to prevent the water immersion sensor mainboard from detaching from the second slot.

[0066] The first and second slots can be respectively located in the central area of ​​the battery mounting component. For example... Figure 15 As shown, a plurality of support ribs 4112 are evenly arranged on the circumferential edge of the bottom wall of the mounting cavity 411. The battery mounting component 431 is disposed in the mounting cavity. The water immersion sensor main board 420 faces the bottom of the mounting cavity, and the edge of the water immersion sensor main board 420 contacts the support ribs 4112.

[0067] The mounting cavity has a circular sidewall, and a square surrounding wall surrounds the circular mounting cavity, forming an outer shell with the mounting cavity. The end of the surrounding wall is lower than the end of the mounting cavity, and the contact point between the surrounding wall and the mounting cavity forms an L-shaped structure. The battery mounting component 431 is positioned at one end of the first slot, with its sidewall recessed inwards by a certain distance. This sidewall is threaded, and a locking and fixing position is located on the sidewall below the thread of the battery mounting component 431. After the battery mounting component 431 is placed in the mounting cavity, a positioning groove exists between the end of the battery mounting component and the end of the mounting cavity.

[0068] The cover plate has two circumferentially spaced circular mounting rings and a square sidewall. The circular mounting rings are longer than the square sidewalls. The circular mounting rings have internal threads that connect with the external threads of the battery mounting component. The square sidewalls match the shape of the square enclosure. The end of the mounting cavity is inserted into the spacer groove between the circular mounting rings and the square sidewalls. A sealing strip, which can be a silicone ring, is provided at the bottom of the spacer groove. The battery mounting component is a mounting bracket. A button battery can be placed in the mounting bracket, and the battery cover can be closed to hold the battery in place. The silicone ring is inserted into the waterproof groove of the front cover. The inner threads of the front cover can be tightened clockwise and loosened counterclockwise by rotating it with the outer threads of the mounting bracket.

[0069] Battery replacement method for the water immersion sensor: The cover plate is designed with internal threads and the fixing bracket has external threads, allowing the bottom shell to be unscrewed directly by hand to replace the battery without the need for tools. The battery slot, i.e., the first slot, has two radially symmetrically arranged engaging plates extending outwards from the slot sidewall. The bottom of the engaging plates connects to the bottom wall of the battery slot, while the side and top walls of the engaging plates are separate from the battery slot. The first slot has a locking platform near the slot opening that engages with the battery cover plate. The bottom wall edge of the first slot has a slot for a metal spring connecting to the water immersion sensor motherboard, which connects to the battery. The engaging plate sidewall has protrusions extending inwards from the slot. The cover plate has radially symmetrically arranged outwardly extending protrusions, each with a groove on its outer sidewall that engages with the corresponding protrusion. The central area of ​​the protrusion has an opening for opening the cover. The battery is connected to the water immersion sensor motherboard via a metal connector between the battery slot sidewall and bottom wall. When removing the battery cover, you can use a screwdriver to push into the opening, move the locking plate under the battery cover, and pry up the battery cover to remove the battery.

[0070] like Figure 17 As shown, the water immersion sensor body 400 further includes a second magnetic member 470, which is disposed in the central region of the water immersion sensor motherboard 420, such that the second magnetic member is located between the water immersion sensor motherboard 420 and the bottom wall of the mounting cavity 411.

[0071] A magnetic patch is provided between the second magnetic component 470 and the water immersion sensor mainboard 420. The second magnetic component is used to engage with the first magnetic component, thereby connecting the water immersion line to the water immersion sensor body.

[0072] When the first end 320 includes the first magnetic attractor 324, assembling the water immersion wire 300 and the water immersion sensor body 400 includes: aligning the through hole 3231 of the second end 330 of the water immersion wire 300 with the corresponding probe 450; bringing the outer shell 410 of the water immersion sensor body 400 close to the shell 321 of the second end 330; attracting the first magnetic attractor 324 and the second magnetic attractor 470 to each other, thus combining the water immersion wire and the water immersion sensor body; and having one end of the probe 450 abut against the U-shaped spring piece 325 through the corresponding through hole 3231. The probe is electrically connected to the water immersion sensor main board at the other end, making the water immersion line main board 340 and the water immersion sensor main board 420 conductive. Disassembling the water immersion line 300 from the water immersion sensor body 400 includes: overcoming the attraction of the first magnetic attraction member 324 and the second magnetic attraction member, separating the outer shell 410 of the water immersion sensor body 400 from the second end 330 shell 321, disengaging one end of the probe 450 from the corresponding through hole 3231, and disengaging the other end of the probe from the water immersion sensor main board under the action of the elastic member, so that the water immersion line is separated from the water immersion sensor body.

[0073] The second magnetic component in this embodiment can be either a magnet or a magnetic iron sheet. After the water immersion line and the water immersion sensor are attached, they are connected by attraction through the magnet and the magnetic iron sheet. At this time, the water immersion spring and the water immersion probe can make contact and conduct. The water immersion line detection signal is transmitted to the water immersion sensor mainboard PCB. That is, the U-shaped spring abuts against the probe, connecting the water immersion line mainboard and the water immersion sensor mainboard, realizing the detection function of the water immersion sensor. The water immersion line and the water immersion sensor body are thus free to be disassembled, purchased, and combined. The first and second magnetic components are magnetic materials, which can be specifically set according to the actual situation.

[0074] like Figure 14 As shown, another embodiment of this disclosure provides a water immersion sensor, including: a water immersion line as described above and a water immersion sensor body as described above.

[0075] The water immersion sensor of this disclosure embodiment can have one water immersion sensor body and multiple water immersion wires connected in series. Alternatively, it can have multiple water immersion sensor bodies and multiple water immersion wires connected in series, in any combination.

[0076] The above description is only a preferred embodiment of the present disclosure. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present disclosure, and these improvements and modifications should also be considered within the protection scope of the present disclosure.
