Description

Technical Field

[0001] The present invention relates to a detection device, in particular to a water treatment device and a water leakage alarm device and a water leakage detection device thereof, and an assembling method and a water leakage detection method of the water leakage detection device. Background Art

[0002] Water treatment equipment is widely used in daily life and industrial production. For example, water softeners, water purifiers, and other water treatment devices improve the quality of water used in daily life and are therefore popular among consumers. However, a common problem with water treatment equipment during use is leakage. Water treatment equipment typically requires high sealing performance for its internal components. Problems such as cracks in pipes, valve failures, substandard precision between components, and gaps between interconnecting parts can cause water leakage during use. If a water treatment device leaks during use and is not discovered in time, it inevitably causes a series of problems for users. First, most water treatment equipment requires a direct power supply to operate. Leakage can easily cause a short circuit, damaging the water treatment equipment. In severe cases, it can cause electric shock to the user, threatening their life. Second, prolonged leakage not only wastes water resources but also leads to significant water accumulation in the environment where the water treatment equipment is used, soaking surrounding equipment and furniture, resulting in financial losses for users.

[0003] In order to promptly detect water leakage in water treatment equipment and reduce safety hazards, existing water treatment equipment uses a water leakage alarm to detect whether the water treatment equipment is leaking. Specifically, the water treatment equipment includes a water treatment body and at least one water leakage alarm, the water leakage alarm is installed on the water treatment body, wherein the water leakage alarm includes a water leakage detection device and an alarm device, the water leakage detection device is communicatively connected to the alarm device, the water leakage detection device includes a control circuit board and a pair of probes, the pair of probes are fixed to one side of the control circuit board, the probes are electrically connected to the control circuit board, the control circuit board has a mounting hole distributed on both sides, the control circuit board is installed on the water treatment body through the mounting hole in a manner that the probes face the internal space of the water treatment body, so that the probes installed on the control circuit board remain in the internal space of the water treatment body. Once a leak occurs inside the water treatment system, water passes through the leak detection device, electrically connecting the pair of probes and completing the circuit. The alarm device, which is communicatively connected to the control circuit, sounds an alarm, alerting the user to promptly detect the leak and repair it, thereby minimizing the damage caused by the leak. However, the leak detection device of the leak alarm has many problems in actual use.

[0004] First, the installation and disassembly process of the existing water leakage detection device is cumbersome. In order to promptly detect water leakage in the water treatment equipment, the control circuit board of the water leakage detection device is usually fixed to the bottom of a shell of the water treatment body by screws, and a water treatment body is installed in the shell to complete the assembly of the water treatment body. In addition, the control circuit board of the existing water leakage detection device is installed at the bottom of the shell in a top-down manner, that is, the control circuit board enters the bottom of the housing cavity of the shell through an opening of a housing cavity in the shell, which is inefficient for installation. In addition, once the pair of probes fixed to the control circuit board detect that the water treatment body is leaking, the user needs to first disassemble the shell and the water treatment body of the water treatment body, then remove the control circuit board fixed to the bottom of the shell, wipe off the moisture, and then deactivate the alarm of the alarm device connected to the control circuit board. The disassembly and assembly process is complicated and wastes the user's time. Furthermore, for inexperienced users, the installation and removal operations are difficult, and the control circuit board and the probe are easily damaged during the installation and removal process, which increases the use cost and maintenance cost of the water leakage alarm.

[0005] Secondly, the volume of the pair of probes is small and they occupy a small proportion of the area of the control circuit board. If the water treatment body leaks, the water can easily bypass the probes, causing the circuit of the control circuit board to be disconnected. As a result, the water leakage detection device is difficult to detect the leakage, causing the water leakage alarm to be useless, and the water treatment equipment leakage phenomenon cannot be discovered in time.

[0006] In addition, the existing water leakage detection device is installed on the shell in a manner of being close to the inner wall of the shell of the water treatment body, and the probe arranged on the control circuit board is installed on one side of the control circuit board in a manner of facing the internal space of the water treatment body. That is to say, the existing water leakage detection device can only detect whether there is water leakage inside the water treatment body. If the water treatment body of the water treatment body leaks, but the water flow does not pass through the internal space but flows directly to the outside, the water leakage detection device cannot detect that the water treatment equipment is leaking.

[0007] In addition, once the air in the internal space of the water treatment body is humid, water droplets in the air may easily cause the pair of probes directly exposed to the air to be turned on, thereby causing the alarm device to give a false alarm, causing trouble to the user.

That is, a gap exists between the positive control unit 111 and the negative control unit 112. The first conductive unit 12 and the second conductive unit 13 are electrically connected to the positive control unit 111 and the negative control unit 112, respectively, and a predetermined distance exists between the first conductive unit 12 and the second conductive unit 13, meaning that the control circuit board 11 remains in an open circuit state. When water enters the internal detection space 30 and the external detection space 40, electrically connecting the first conductive unit 12 and the second conductive unit 13, the circuit is completed, and the control circuit board 11 is in a closed circuit state. The alarm device 200, communicatively connected to the positive control unit 111 and the negative control unit 112, is capable of generating an alarm. It is worth noting that a predetermined distance exists between the first conductive unit 12 and the second conductive unit 13, located in the negative control unit 112 and the positive control unit 111. This prevents the gap between the first conductive unit 12 and the second conductive unit 13 from being too large, causing water to flow between the first conductive unit 12 and the second conductive unit 13 without connecting them. It also prevents the gap between the first conductive unit 12 and the second conductive unit 13 from being too small, causing the first conductive unit 12 and the second conductive unit 13 to be connected by small water droplets in the air. Preferably, the distance between the first conductive unit 12 and the second conductive unit 13 is 2.54 cm. Those skilled in the art should understand that the distance between the first conductive unit 12 and the second conductive unit 13 is merely an example and does not limit the scope of the water leakage detection device 100 of the present invention. It is worth mentioning that the positive control unit 111 and the negative control unit 112 described in the specification are for the purpose of facilitating understanding of the two states of the control circuit board 11 when it is in the open circuit and the open circuit. The specific electrodes of the positive control board 111 and the negative control unit 112 and their implementation methods are only for illustration and cannot be used to limit the content and scope of the water leakage detection device 100 described in the present invention.

[0095] Preferably, the specific number of the first conductive unit 12 and the second conductive unit 13 is implemented as a plurality. By increasing the number of the first conductive unit 12 and the second conductive unit 13, the area ratio of the first conductive unit 12 and the second conductive unit 13 to the control circuit board 11 is increased, thereby reducing the probability that water entering the internal detection space 30 and the external detection space 40 will avoid the first conductive unit 12 and the second conductive unit 13, further facilitating improved detection accuracy of the water leakage detection device 100. Preferably, the specific number of the first conductive unit 12 and the second conductive unit 13 is three, respectively. Those skilled in the art will understand that the specific number of the first conductive unit 12 and the second conductive unit 13 shown in the drawings is merely illustrative and does not limit the scope of the water leakage detection device 100 of the present invention. The specific number of the first conductive unit 12 and the second conductive unit 13 can be one or more.

[0096] Furthermore, a plurality of the first conductive units 12 are electrically connected in series to the positive control portion 111 of the control circuit board 11, and a plurality of the second conductive units 12 are electrically connected in series to the negative control portion 112 of the control circuit board 11. Figure 3B , which shows a partial circuit diagram of the water leakage detection device 100 in which the first conducting unit 12 and the second conducting unit 13 are both implemented in three.

[0097] Preferably, the number of the first conducting units 12 and the second conducting units 13 are the same, that is, the number of the first conducting units 12 and the second conducting units 13 corresponds one to one, and each first conducting unit 12 corresponds to one second conducting unit 13. The first conducting units 12 and the second conducting units 13 are provided in pairs on the control circuit board 11.

[0098] Optionally, the number of the first conducting units 12 and the number of the second conducting units 13 are inconsistent. Figure 6The number of first conductive units 12 and second conductive units 13 is one-to-many, that is, the number of first conductive units 12 can be implemented as one, with one first conductive unit 12 electrically connected to the positive control unit 111 of the control circuit board 11, and the number of second conductive units 13 can be implemented as multiple, with multiple second conductive units 13 distributed around the first conductive unit 12 and electrically connected in series to the negative control unit 112 of the control circuit board 11. When water entering the internal detection space 30 and the external detection space 40 causes the first conductive unit 12 to be electrically connected to any one of the second conductive units 13, the circuit is conductive, the control circuit board 11 is in a conductive state, and the alarm device 200, which is communicatively connected to the control circuit board 11, can sound an alarm. It should be understood that the specific number and positional relationship of the first inner conductive member 121, the second inner conductive member 131, the second outer conductive member 132 and the first outer conductive portion 122 described in the drawings and description of the specification are merely examples and cannot limit the content and scope of the water leakage detection device 100 described in the present invention.

[0099] It is worth mentioning that the first conductive unit 12 and the second conductive unit 13 have excellent electrical conductivity, and the specific material of the first conductive unit 12 and the second conductive unit 13 is not limited. The first conductive unit 12 and the second conductive unit 13 can be implemented as, but not limited to, copper, silver, aluminum, iron, tin, etc. In addition, the shape of the first conductive unit 12 and the second conductive unit 13 is not limited. The cross-sectional shape of the first conductive unit 12 and the second conductive unit 13 can be implemented as, but not limited to, circular, rectangular, elliptical, polygonal, etc. Furthermore, the first conductive unit 12 and the second conductive unit 13 can be implemented as, but not limited to, being electrically connected to the controlled circuit board 11 via soldering. The specific embodiments of the first conductive unit 12 and the second conductive unit 13 are merely examples and are not intended to limit the content and scope of the water leakage detection device 100 of the present invention.

[0100] Furthermore, the first conductive unit 12 and the second conductive unit 13 have a predetermined length, thereby enabling water entering the inner detection space 30 to electrically connect the first conductive unit 12 and the second conductive unit 13 simply by passing through the first inner detection end 1201 of the first conductive unit 12 and the second inner detection end 1301 of the second conductive unit 13. Similarly, water entering the outer detection space 40 can electrically connect the first conductive unit 12 and the second conductive unit 13 simply by passing through the first outer detection end 1202 of the first conductive unit 12 and the second outer detection end 1302 of the second conductive unit 13, thereby improving the sensitivity of the water leakage detection device 100.

[0101] Refer to the instruction manual Figure 2A 、 Figure 2B 、 Figure 3A 、 Figure 5 as well as Figure 6 The first conductive unit 12 further includes a first inner conductive member 121 and a first outer conductive portion 122, the first inner conductive member 121 and the first outer conductive portion 122 are respectively electrically connected to the positive control portion 111 of the control circuit board 11, and the first inner conductive member 121 and the first outer conductive portion 122 are respectively arranged on both sides of the control circuit board 11, that is, the first inner conductive member 121 is located in the internal detection space 30, and the first outer conductive portion 122 is located in the external detection space 40. Correspondingly, the second conductive unit 13 further includes a second inner conductive member 131 and a second outer conductive member 132. The second inner conductive member 131 and the second outer conductive member 132 are respectively electrically connected to the negative pole control part 112 of the control circuit board 11. The second inner conductive member 131 and the second outer conductive member 132 are respectively arranged on both sides of the control circuit board 11. The second inner conductive member 131 is located in the internal detection space 30, and the second outer conductive member 132 is located in the external detection space 40. Once water enters the internal detection space 30 and electrically connects the first internal conductive member 121 and the second internal conductive member 131, that is, the positive control board 111 and the negative control board 112, the circuit is conducted, and the control circuit board 11 is in a conductive state. Similarly, once water enters the external detection space 40 and electrically connects the first external conductive portion 122 and the second external conductive portion 132, the circuit is also conducted, and the control circuit board 11 is in a conductive state. Therefore, the water leakage detection device 100 can simultaneously detect the internal detection space 30 and the external detection space 40, so as to promptly detect water leakage, reduce the losses caused by water leakage, and improve the practicality of the water leakage detection device 100.

[0102] Continue to refer to the instruction manual Figure 2A 、 Figure 2B 、 Figure 3A 、 Figure 5 as well as Figure 6 In some embodiments of the present invention, the water leakage detection body 10 of the water leakage detection device 100 further includes an internal detection unit 101 and an external detection unit 102, wherein the internal detection unit 101 and the external detection unit 102 extend respectively on both sides of the control circuit board 11. Furthermore, the internal detection unit 101 is located within the internal detection space 30 to detect whether there is water leakage in the internal detection space 30; the external detection unit 102 is located within the external detection space 40 to detect whether there is water leakage in the external space 40. Specifically, the internal detection unit 101 includes at least one first internal conductive part 121 and at least one second internal conductive part 131. When the first internal conductive part 121 and the second internal conductive part 131 of the internal detection unit 101 located in the internal detection space 30 are conducted by water flow, the positive control board 111 and the negative control board 112 are electrically connected, the circuit is conducted, the control circuit board 11 is in a conductive state, and the alarm device 200 communicatively connected to the positive control part 111 and the negative control part 112 can alarm. In addition, the external detection unit 102 includes at least one first external conductive member 122 and at least one second external conductive member 132. When the first external conductive member 122 and the second external conductive member 132 of the external detection unit 102 located in the external detection space 40 are conducted by water flow, the positive control board 111 and the negative control board 112 are electrically connected, the circuit is conducted, the control circuit board 11 is in a conductive state, and the alarm device 200 communicatively connected to the positive control part 111 and the negative control part 112 can alarm.

[0103] Preferably, refer to Figure 5 The internal detection unit 101 includes a plurality of first internal conductive members 121 and a plurality of second internal conductive members 131, and the number of the first internal conductive members 121 and the number of the second internal conductive members 131 correspond to each other. In other words, the first internal conductive members 121 and the second internal conductive members 131 are provided in pairs on the control circuit board 11. Preferably, the specific number of the first internal conductive members 121 and the second internal conductive members 131 is three, respectively, that is, three pairs of the first internal conductive members 121 and the second internal conductive members 131 are provided on one side of the control circuit board 11.

[0104] Preferably, refer to Figure 5The external detection unit 102 includes a plurality of first external conductive members 122 and a plurality of second external conductive members 132, and the number of the first external conductive members 122 and the number of the second external conductive members 132 correspond to each other. Preferably, the specific number of the first external conductive members 122 and the second external conductive members 132 is implemented as three, that is, three pairs of the first external conductive members 122 and the second external conductive members 132 are provided on the other side of the control circuit board 11.

[0105] Preferably, refer to Figure 6 The internal detection unit 101 includes a first inner conductive member 121 and a plurality of second inner conductive members 131. The plurality of second inner conductive members 131 are disposed around the first inner conductive member 121. When any one of the second inner conductive members 131 is connected to the first inner conductive member 121 by water, the circuit is completed. Correspondingly, the external detection unit 102 includes a first outer conductive portion 122 and a plurality of second outer conductive members 132. The plurality of second outer conductive members 132 are disposed around the first inner conductive member 122. When any one of the second outer conductive members 132 is connected to the first outer conductive portion 122 by water, the circuit is completed. It is worth noting that the specific numbers of the first inner conductive member 121 and the second inner conductive member 131 of the internal detection unit 101 and the first outer conductive member 122 and the second outer conductive member 132 of the external detection unit 102 are merely examples and do not limit the content and scope of the water leakage detection device of the present invention.

[0106] Reference Figure 3AIn this specific embodiment of the water leakage detection device 100 according to the present invention, the first inner conductive member 121 and the first outer conductive member 122 of the first conductive unit 12 are integrally formed. The second inner conductive member 131 and the second outer conductive member 132 of the second conductive unit 13 are integrally formed. In other words, the first conductive unit 12 and the second conductive unit 13 are mounted on the control circuit board 11 so as to penetrate the control circuit board 11. Specifically, the control circuit board 11 has at least two positioning holes 113, and the first conductive unit 12 and the second conductive unit 13 are mounted on the control circuit board 11 in a manner corresponding to the positioning holes 113, so that the first conductive unit 12 and the second conductive unit 13 are respectively electrically connected to the control circuit board 11. The portions of the first conductive unit 12 and the second conductive unit 13 located within the internal detection space 30 on one side of the control circuit board 11 are the first inner conductive member 121 and the second inner conductive member 131, respectively. The portions of the first conductive unit 12 and the second conductive unit 13 located within the external detection space 40 on the other side of the control circuit board 11 are the first outer conductive portion 122 and the second outer conductive member 132, respectively. In other words, in this specific embodiment of the present invention, the first inner conductive member 121 of the internal detection unit 101 and the second inner conductive member 131 of the external detection unit 102 of the water leakage detection body 10 are integrally formed, and the second inner conductive member 122 of the internal detection unit 101 and the second outer conductive member 132 of the external detection unit 102 are integrally formed.

[0107] It is worth mentioning that the specific implementation method of fixing the first conduction unit 12 and the second conduction unit 13 to the control circuit board 11 and electrically connecting the control circuit board 11 to the first conduction unit 12 and the second conduction unit 13 is not limited. For example, the first conduction unit 12 and the second conduction unit 13 can be fixed to the control circuit board 11 and electrically connected to the control circuit board 11 by means of, but not limited to, soldering.

[0108] Preferably, refer to Figure 3AThe water leakage detection body 10 further includes at least one assembly member 14, which is sleeved on the first conductive unit 12 and the second conductive unit 13 to facilitate the installation of the first conductive unit 12 and the second conductive unit 13 on the control circuit board 11. Specifically, the size of the assembly member 14 is adapted to the positioning hole 113 of the control circuit board 11, so that the first conductive unit 12 and the second conductive unit 13 can be fixed to the control circuit board 11 in a manner in which the assembly member 14 cooperates with the inner wall forming the positioning hole 113, so that the first conductive unit 12 and the second conductive unit 13 are electrically connected to the control circuit board 11 by soldering, and at the same time, the first conductive unit 12 and the second conductive unit 13 are more firmly connected to the control circuit board 11.

[0109] Furthermore, the assembly member 14 is movably mounted to the first conductive unit 12 and the second conductive unit 13 to adjust the lengths of the first inner conductive member 121, the first outer conductive portion 122 of the first conductive unit 12, and the second inner conductive member 131 and the second outer conductive member 132 of the second conductive unit 13. Specifically, the assembly member 14 is fixed to a predetermined position in the first conductive unit 12 and the second conductive unit 13 by sliding the assembly member 14 left and right relative to the first conductive unit 12 and the second conductive unit 13. Furthermore, the first conductive member 11 is fixed to the control circuit board 11, so that the portion on one side of the assembly member 14 becomes the first inner conductive member 121, and the portion on the other side of the assembly member 14 becomes the first outer conductive portion 122. Similarly, the second conductive member 12 is fixed to the control circuit board 11. The portion located on one side of the assembly 14 is the second inner conductive member 131, and the portion located on the other side of the assembly 14 is the second outer conductive member 132. In other words, the lengths of the first inner conductive member 121, the first outer conductive member 122, the second inner conductive member 131, and the second outer conductive member 132 can be adjusted via the assembly 14. It is worth noting that the lengths of the first inner conductive member 121, the first outer conductive member 122 of the first conductive unit 12, and the second inner conductive member 131 and second outer conductive member 132 of the second conductive unit 13 are not limited. The lengths of the first inner conductive member 121, the first outer conductive member 122, the second inner conductive member 131, and the second outer conductive member 132 of the first conductive unit 12 can be the same or different.

[0110] Reference Figure 5In other embodiments of the present invention, the first conductive unit 12 and the second conductive unit 13 are implemented as split structures, that is, at least one first internal conductive portion 121 and at least one first external conductive portion 122 are independently disposed on either side of the control circuit board 11. In other words, the first internal conductive portion 121 and the first external conductive portion 122 are spaced apart from each other and disposed on either side of the control circuit board 11. Correspondingly, at least one second internal conductive portion 131 and at least one second external conductive portion 132 are independently disposed on either side of the control circuit board 11. In other words, the second internal conductive portion 131 and the second external conductive portion 132 are spaced apart from each other and disposed on either side of the control circuit board 11. For example, the first internal conductive portion 121, the first external conductive portion 122, the second internal conductive portion 131, and the second external conductive portion 132 can be directly fixed to the control circuit board 11 by soldering and electrically connected to the control circuit board 11. That is, in this specific embodiment of the present invention, the internal detection unit 101 and the external detection unit 102 of the water leakage detection body 10 are independently located on either side of the control circuit board 11. It should be understood that the specific number of control circuit boards 11 is not limited. In other embodiments of the present invention, the number of control circuit boards 11 may be two, with the two control circuit boards 11 disposed one above the other, and the internal detection unit 101 and the external detection unit 102 disposed on different sides of the two circuit boards 11.

[0111] Furthermore, the water leakage detection body 10 of the water leakage detection device 100 further includes a protective layer 15. The protective layer 15 is formed on the control circuit board 11 in a manner that covers the control circuit board 11 to prevent the control circuit board 11 from being corroded during use, or to prevent water entering the inner detection space 30 and the outer detection space 40 from causing a short circuit in the electrical components of the control circuit board 11, or to prevent dust from covering the control circuit board 11 and affecting the performance of the water leakage detection device 100. As a result, the protective layer 15 can increase the service life of the control circuit board 11. The specific material of the protective layer 15 is not limited. For example, the protective layer 15 can be implemented, but is not limited to, by forming a material with good insulation, such as silicone, epoxy resin, polyurethane, etc., on the control circuit board 11 through glue potting or other processes, and wrapping the control circuit board 11.

[0112] Reference Figure 7Preferably, the protective layer 15 has at least one guide groove 151 formed between the first conductive unit 12 and the second conductive unit 13. The guide groove 151 guides water entering the inner detection space 30 and the outer detection space 40 between the first conductive unit 12 and the second conductive unit 13, thereby electrically connecting the first conductive unit 12 and the second conductive unit 13 and completing the circuit. In other words, the first conductive unit 12 and the second conductive unit 13 are located at opposite ends of the guide groove 151, respectively, preventing water entering the inner detection space 30 and the outer detection space 40 from bypassing the first conductive unit 12 and the second conductive unit 13, thereby improving the sensitivity of the water leakage detection device 100.

[0113] Optionally, the guide groove 151 is located in the non-adjacent first conductive unit 12 and can guide water to between the non-adjacent first conductive unit 12 and the second conductive unit 13. Once a fault occurs between the adjacent first conductive units 12 or second conductive units 13, it will not affect the sensitivity of the water leakage detection device 100.

[0114] Refer to the attached Figure 2A The assembly body 20 of the water leakage detection device 100 includes an inner assembly portion 23 and an outer assembly portion 24. The outer assembly portion 24 integrally extends from the inner assembly portion 23, and the assembly space 21 is formed between the inner assembly portion 23 and the outer assembly portion 24. The control circuit board 11 is held in the assembly space 21, and the inner detection space 30 is formed between the control circuit board 11 and the inner assembly portion 23, and the outer detection space 40 is formed between the control circuit board 11 and the outer assembly portion 24.

[0115] Further, refer to the attached Figure 2A The inner assembly portion 23 includes a limiting portion 231, which integrally extends from the inner wall 22 of the assembly body 20 into the assembly space 21. The control circuit board 11 can be implemented to enter the assembly space 21 from an opening of the assembly space 21, and the control circuit board 11 is disposed on the limiting portion 231. The limiting portion 231 can support the control circuit board 11 of the water leakage detection body 10, so that the control circuit board 11 can be suspended and held in the assembly space 21 of the assembly body 20. This prevents the first conductive unit 12 and the second conductive unit 13 fixed to the control circuit board 11 from tilting or being knocked down when the water leakage detection device 100 is impacted, thereby affecting the sensitivity of the water leakage detection body 10.

[0116] Further, refer to the attached Figure 2AThe inner assembly portion 23 includes at least one limiting protrusion 232 and defines a limiting space 233. The limiting protrusion 232 integrally extends from the inner wall 22 of the assembly body 20 into the assembly space 21. The limiting protrusion 232 is spaced apart and located above the limiting portion 231. The limiting space 233 is formed between the limiting portion 231 and the limiting protrusion 232. The limiting space 233 communicates with the assembly space 21. The control circuit board 11 can be fixed in the limiting space 233, that is, the control circuit board 11 is retained between the limiting portion 231 and the limiting protrusion 232, preventing the control circuit board 11 from shaking in the assembly space 27 and affecting the sensitivity of the water leakage detection body 10.

[0117] Specifically, the limiting protrusion 232 is elastic and has an inclined surface 2321. The diameter of the control circuit board 11 matches the diameter of the assembly space 21. The control circuit board 11 can laterally enter the assembly space 21 from the opening of the assembly space 21 with its outer wall abutting against the inner wall 22 of the assembly body 20. The control circuit board 11 presses against the inclined surface 2321 of the limiting protrusion 232, causing the limiting protrusion 232 to deform, allowing the control circuit board 11 to pass through the limiting protrusion 232 and enter the limiting space 233. Once the control circuit board 11 enters the limiting space 233, the squeezing force exerted on the limiting protrusion 232 by the control circuit board 11 disappears, and the limiting protrusion 232 recovers its deformation, securing the control circuit board 11 within the limiting space 233. This prevents the control circuit board 11 from shaking within the assembly space 27 and affecting the sensitivity of the water leakage detection body 10.

[0118] In addition, refer to the attached Figure 2AThe inner assembly portion 23 further includes at least one guide portion 234 extending vertically upward from the limiting portion 231 of the assembly body 20. The guide portion 234 is capable of guiding the control circuit board 11 into the limiting space 21 after entering the assembly space 21. Accordingly, the control circuit board 11 has an assembly hole 114. The guide portion 234 of the inner assembly portion 23 is capable of being received in the assembly hole 114 of the control circuit board 11. The shape and size of the assembly hole 114 are adapted to the cross-sectional dimensions of the guide portion 234, so that the outer wall of the control circuit board 11 can fit closely to the outer wall of the guide portion 234. Preferably, the cross-sections of the assembly hole 114 and the limiting portion 231 are both semicircular. Moreover, when the outer wall of the control circuit board 11 fits into the outer wall of the guide portion 234, the control circuit board 11 can be perpendicular to the inner wall 22 of the assembly body 20, that is, the control circuit board 11 and the assembly body 20 have the same central axis, and the control circuit board 11 can always be placed in the assembly space 20 of the assembly body 20 in a balanced manner, thereby preventing the control circuit board 11 from tilting during the installation process, and further preventing the first conductive unit 12 and the second conductive unit 13 fixed to the control circuit board 11 from being hit during the installation process, thereby saving assembly time and improving assembly efficiency.

[0119] Further, refer to the attached Figure 2A The inner assembly portion 23 has at least one inner guide channel 235. The inner guide channel 231 communicates with the assembly space 23. The inner guide channel 235 can guide water from the water inlet 2351 of the inner guide channel 235 through the water outlet 2352 of the inner guide channel 235 into the inner detection space 30, thereby allowing the water to flow through the first conduction unit 12 and the second guide member 13. The outer assembly portion 24 has at least one outer guide channel 241. The outer guide channel 241 communicates with the assembly space 24. The outer guide channel 241 can guide water from the water outlet 2411 of the outer guide channel 241 through the water outlet 2412 of the outer guide channel 241 into the outer detection space 40, thereby allowing the water to flow through the first conduction unit 12 and the second conduction unit 13.

[0120] Preferably, the cross-sections of the inner guide channel 235 and the outer guide channel 241 are trapezoidal, that is, the size of the water inlet 2351 of the inner guide channel 235 is larger than the size of the water outlet 2352 of the inner guide channel 235, and the size of the water inlet 2411 of the outer guide channel 241 is larger than the size of the water outlet 2412 of the outer guide channel 241, thereby forming an inclined surface between the water inlet 2351 of the inner guide channel 235 and the water outlet 2352 of the inner guide channel 235, and also forming an inclined surface between the water inlet 2411 of the outer guide channel 241 and the water outlet 2412 of the outer guide channel 241, which is conducive to guiding the water flow to quickly enter the inner detection space 30 and the outer detection space 40, so as to facilitate timely detection of water leakage.

[0121] Preferably, the water outlet 2352 of the inner guide channel 235 corresponds to the first conduction unit 12 and the second conduction unit 13 located in a pair in the inner detection space 30, so that water flowing into the inner detection space 30 from the water outlet 2352 of the inner guide channel 235 can quickly conduct the corresponding first conduction unit 12 and the second conduction unit 13, thereby improving the sensitivity of the water leakage detection device 100.

[0122] Preferably, the water outlet 2412 of the outer guide channel 241 corresponds to the first conductive unit 12 and the second conductive unit 13, which form a pair within the outer detection space 40. This allows water flowing from the water outlet 2412 of the outer guide channel 241 into the outer detection space 40 to quickly flow through the corresponding first conductive unit 12 and second conductive unit 13, thereby improving the sensitivity of the water leakage detection device 100. It is worth noting that the specific embodiments of the inner guide channel 235 and the outer guide channel 241 are merely examples and are not intended to limit the content and scope of the water leakage detection device 100 of the present invention.

[0123] It is worth mentioning that the inner guide channel 235 and the outer guide channel 241 can promote the flow of air, maintain normal air circulation in the inner detection space 30 and the outer detection space 40, and avoid the situation where the water vapor in the air causes the first conductive unit 12 and the second conductive unit 13 to be electrically connected when the air humidity is high, thereby causing a false alarm.

[0124] Preferably, refer to the attached Figure 2AThe assembly body 20 of the water leakage detection device 100 includes a protective cover 25, which is operably mounted on the upper portion of the inner assembly portion 23 to reduce dust in the air from entering the inner detection space 30 and affecting the sensitivity of the water leakage detection body 10. Once the first conductive unit 12 and the second conductive unit 13 in the inner detection space 30 detect a water leak, the protective cover 25 can be separated from the inner assembly portion 23, and the water in the water leakage detection body 10 can be wiped dry to release the alarm, and the water leakage detection body 10 can continue to be used. Preferably, the protective cover 25 can be mounted on the inner assembly portion 23 by means of a threaded connection. Preferably, the protective cover 25 can be mounted on the inner assembly portion 23 by means of a clearance fit with the inner assembly portion 23. Preferably, the protective cover 25 can be mounted on the inner assembly portion 23 by means of a snap fit with the inner assembly portion 23. Preferably, the protective cover 25 can be pivotally connected to the inner assembly portion 23 to prevent the protective cover 25 from being lost after being separated from the inner assembly portion 23 .

[0125] Preferably, refer to the attached Figure 2A The assembly body 20 further includes a protective base 26, which is detachably mounted on the lower portion of the outer assembly portion 24 to prevent the ends of the first conductive unit 12 and the second conductive unit 13 in the outer detection space 40 from contacting the ground, thereby preventing the first conductive unit 12 and the second conductive unit 13 from being scratched and affecting the normal use of the water leakage detection device 100. Once the first conductive unit 12 and the second conductive unit 13 in the outer detection space 40 detect a water leak, the protective base 26 can be separated from the outer assembly portion 24, and the water in the water leakage detection body 10 can be wiped dry to release the alarm, and the water leakage detection body 10 can continue to be used. Furthermore, the protective base 26 has at least one flow groove 261, which is connected to the outer detection space 40. The outer surface and bottom surface of the protection base 26 are recessed inward to form the flow groove 261 , so as to prevent the protection base 26 from blocking the flow of water, thereby further ensuring the sensitivity of the water leakage detection device 100 .

[0126] It is worth mentioning that the water leakage detection device 100 can be quickly installed on the water treatment device 400 of the water treatment equipment 500 to save installation time, and the water leakage detection device 100 can be quickly separated from the water treatment device 400 so that when the water leakage detection device 100 detects a water leakage, the alarm can be quickly lifted.

[0127] Specifically, refer to the attached Figure 4The water treatment device 400 includes a housing 410 and a water treatment body 420. The housing 410 has a receiving space 411, and the water treatment body 420 is installed in the housing 410. Furthermore, the housing 410 has an assembly passage 412 formed at the bottom of the housing 410. The assembly passage 412 connects the receiving space 411 with the external space, allowing the water leakage detection device 100 to enter the receiving space 411 through the assembly passage 412 and be installed in the water treatment device 400. In other words, the water leakage detection device 100 can be installed in the housing 410 of the water treatment device 400 from bottom to top, with the inner detection space 30 of the water leakage detection device 100 installed in the water treatment device 400 communicating with the receiving space 411 of the housing 410, and the outer detection space 40 of the water leakage detection device 100 communicating with the external space of the housing 410. Once the water treatment body 420 leaks and water flows into the accommodating space 411, the water flowing into the accommodating space 411 can enter the inner detection space 30 through the inner guide channel 235. The water flow causes the first conductive unit 12 and the second conductive unit 13 located in the inner detection space 30 to be electrically connected, thereby completing the circuit and causing the alarm device 200 electrically connected to the control circuit board 11 to sound an alarm. Once the water treatment body 420 leaks, the water flows into the external space of the water treatment device 400 and the water in the external space can enter the external detection space 40 through the flow groove 261 of the protective base 26 and the outer guide channel 241 of the outer assembly portion 24. The water flow causes the first conductive unit 12 and the second conductive unit 13 located in the outer detection space 40 to be electrically connected, thereby completing the circuit and causing the alarm device 200 electrically connected to the control circuit board 11 to sound an alarm.

[0128] More specifically, refer to the attached Figure 2A and Figure 4The assembly body 20 includes two assembly protrusions 27 extending outward from the outer wall of the inner assembly portion 23. Correspondingly, the housing 410 has a mounting notch 413 and a retaining groove 414. The mounting notch 413 and the retaining groove 414 communicate with the assembly channel 412. The dimensions of the mounting notch 413 and the retaining groove 414 correspond to the dimensions and positions of the assembly protrusions 27. The assembly body 20 can enter the assembly channel 412 with the assembly protrusions 27 corresponding to the mounting notches 413, and the assembly protrusions 27 can be retained in the retaining groove 414. Specifically, when the assembly protrusion 27 enters the assembly passage 412 through the assembly notch 413 and the assembly protrusion 27 corresponds to the limiting groove 23, the assembly body 20 is rotated within the assembly passage 412 to allow the assembly protrusion 27 to enter the limiting groove 23, thereby securing the water leakage detection device 200 to the housing 410 of the water treatment device 400. Once the water leakage detection device 200 detects a water leak, the assembly body 20 is rotated to allow the assembly protrusion 27 to exit the limiting groove 414, thereby separating the assembly body 20 from the housing 410, allowing the water leakage detection device 100 to be quickly removed and the alarm to be released.

[0129] Further, refer to the attached Figure 4 The housing 410 of the water treatment device 400 includes a housing body 415 and two mounting portions 416. The two mounting portions 416 integrally extend from the bottom edge of the housing body 415, which forms the opening of the mounting passage 412, into the accommodating space 411. The accommodating space 411 is formed in the housing body 413 and the distance between the mounting portions 414 is smaller than the size of the opening of the mounting passage 412. The mounting notch 413 is formed between the mounting portions 414. The inner surfaces of the mounting portions 416 are recessed inward to form the retaining grooves 414. The positions of the mounting portions 416 of the housing 410 of the water treatment device 400 correspond to the positions of the mounting protrusions 27 of the mounting body 20. It should be understood that the specific positions of the limiting groove 414 and the assembly protrusion 27 can be interchanged, that is, the assembly body 20 of the water leakage detection device 100 can be implemented as having the limiting groove 414, and the shell 410 of the water treatment device 400 can also be implemented as including the assembly protrusion 27 respectively.

[0130] Reference Figure 8In other embodiments of the present invention, the water leakage detection device 100 is detachably mounted on the housing 410 of the water treatment device 400 by threaded engagement. Specifically, the housing 410 of the water treatment device 400 includes a mounting portion 418 extending from the bottom of the housing body 415 into the accommodating space 411. The inner wall of the mounting portion 418 has an internal thread. The outer surface of the inner mounting portion 23 of the assembly body 20 of the water leakage detection device 100 has an external thread that matches the internal thread, allowing the water leakage detection device 100 to be mounted on the water treatment device 400 by threaded engagement.

[0131] Refer to the attached Figure 9 In other embodiments of the present invention, the water treatment device 400 can guide the water leakage detection device 100 to be installed in the water treatment device 400. Specifically, the housing 410 includes at least one magnetic member 419, which is embedded in the mounting portion 418. Correspondingly, the assembly body 20 of the water leakage detection device 100 includes at least one adsorption member 28, which is embedded in the inner mounting portion 23. The magnetic member 419 and the adsorption member 28 attract each other, thereby allowing the assembly body 20 of the water leakage detection device 100 to enter the assembly channel 411 of the housing 410 of the water treatment device 400. At the same time, the assembly body 20 of the water leakage detection device 100 can be installed in the housing 410 of the water treatment device 400 in a manner such that the adsorption member 28 is adsorbed by the magnetic member 419. The magnetic member 419 and the adsorption member 28 can be implemented as magnets, or one of them can be a magnet and the other can be a metal that can be attracted by a magnet.

[0132] In addition, in other possible examples of the present invention, the shell 410 of the water treatment device 400 can provide other guiding methods to guide the water leakage detection device 100 to be installed in the shell 410 of the water treatment device 400. For example, a chamfer can be set at the installation position of the shell 410.

[0133] It is worth noting that the specific embodiment of quickly mounting the water leakage detection device 100 on the housing 410 of the water treatment device is merely illustrative and does not limit the content and scope of the water leakage detection device 100 of the present invention. Those skilled in the art will readily appreciate other embodiments. For example, the water leakage detection device 100 may be removably mounted on the water treatment device 400 via a clearance fit or a snap fit.

[0134] Further, refer to the attached Figure 2A 、 Figure 4 、 Figure 8 as well as Figure 9 The assembly body 20 of the water leakage detection device 100 further includes a sealing member 29, which is retained between the assembly body 20 of the water leakage detection device 100 and the housing 410 of the water treatment device 400. The sealing member 29 prevents water in the accommodating space 411 of the water treatment device 400 from escaping through the gap between the assembly body 20 of the water leakage detection device 100 and the housing 410 of the water treatment device 400. This prevents the water in the accommodating space 411 from failing to enter the inner detection space 30, thereby preventing the water leakage detection device 100 from failing to detect water leakage in a timely manner. This further helps to improve the sensitivity of the water leakage detection device 100. Preferably, the sealing member 29 is annular, and the sealing member 29 is fitted onto the inner assembly portion 23, so that when the mounting housing 20 is installed in the housing 410, the sealing member 29 can be retained between the inner assembly portion 23 and the housing 410. Preferably, the seal 29 is elastic and can be implemented as but not limited to a silicone seal or a rubber seal, wherein the seal 29 is elastically deformed by being squeezed by the inner assembly part 23 and the shell 410 to prevent a gap from being generated between the inner assembly part 23 and the shell 410.

[0135] The inner assembly part 23 of the assembly body 20 of the water leakage detection device 100 further has a retaining groove 236, and the sealing member 29 is retained in the retaining groove 236, so that when the water leakage detection device 100 is installed in the water treatment device 400, the sealing member 29 can be reliably retained in the retaining groove 236, so that after the water leakage detection device 100 is installed in the water treatment device 400, the sealing member 29 is retained between the inner assembly part 23 of the assembly body 20 of the water leakage detection device 100 and the shell 410 of the water treatment device 400. It should be understood that the sealing member 29 is retained in the retaining groove 236 in a manner that protrudes from the outer surface of the inner assembly portion 23, so that after the assembly body 20 of the water leakage detection device 100 is installed in the shell 410 of the water treatment device 400, the inner assembly portion 23 of the assembly body 20 and the shell 410 can provide pressure to deform the sealing member 29, thereby preventing a gap from being generated between the inner assembly portion 23 and the shell 410 by deforming the sealing member 29.
