All publications, patent applications, patents, and other references mentioned in this specification are herein incorporated by reference in their entirety for the purpose of describing and disclosing, for example, the compositions and methodologies which are described in such publications, which describe and define in connection with this application.

[0037] In addition, the technical features involved in different embodiments of the application described below can be combined with each other as long as there is no conflict.

[0038] As Figures 1-3 shown, the alarm device 100 provided by one of the embodiments of the application includes a housing 10, a circuit board 20, a probe set 30, and a reminding mechanism 40. The housing 10 is provided with a receiving cavity 101 and a mounting port 102. The mounting port 102 is in communication with the receiving cavity 101. The circuit board 20, the probe set 30, and the reminding mechanism 40 are all accommodated in the receiving cavity 101. One end of the probe set 30 is connected with the circuit board 20, and the other end of the probe set 30 is exposed outside the housing 10 through the mounting port 102. The reminding mechanism 40 is mounted on the housing 10 and connected with the circuit board 20. The reminding mechanism 40 is configured to work when the probe set 30 detects liquid. In this embodiment, the circuit board 20 and the reminding mechanism 40 are arranged side by side in a first direction X, which is perpendicular to the thickness direction of the housing 10, as shown in Figures 1-2 Figures 1-2 The direction Z in Figure 2 is the thickness direction of the housing 10, The direction X in

[0039] is the first direction X.

[0040] In this way, the circuit board 20 and the reminding mechanism 40 are arranged side by side in the first direction X, which avoids the risk of increasing the overall thickness caused by the stacking of the circuit board 20 and the reminding mechanism 40 in the thickness direction of the housing 10, and is conducive to reducing the overall thickness of the alarm device 100, increasing the application scenarios of the alarm device 100, and improving the user experience.

[0041] In some embodiments, as Figures 2-3As shown, the shell 10 comprises a bottom shell 11 and a shell body 12 connected together. Among them, the side of the shell body 12 facing the bottom shell 11 is provided with a convex edge 121, and the side of the bottom shell 11 facing the shell body 12 is provided with a groove 111, and the convex edge 121 is inserted into the groove 111 to realize the positioning and installation of the bottom shell 11 and the shell body 12. In this embodiment, the shape of the convex edge 121 is annular, and the shape of the groove 111 is annular, and when the convex edge 121 is inserted into the groove 111, a barrier can be formed around, compared with the way of setting only part of the convex edge 121 and the groove 111, it is beneficial to improve the sealing performance of the connection between the bottom shell 11 and the shell body 12.

[0042] The connection mode between the bottom shell 11 and the shell body 12 can be connected by clamping, or can be connected by screwing through connecting pieces such as bolts, or can be bonded, and of course can be other, the specific connection mode can be set according to the needs. In this embodiment, the bottom shell 11 and the shell body 12 are connected by clamping.

[0043] In some embodiments, as shown in Figure 2 The bottom shell 11 is provided with a barb 112 and a first socket 113, and the first barb 112 and the first socket 113 are respectively arranged on both sides of the bottom shell 11. The shell body 12 is provided with a second socket 122 and a clamping convex 123, and the second socket 122 and the clamping convex 123 are respectively arranged on both sides of the shell body 12. Among them, the barb 112 is clamped with the second socket 122, and the first socket 113 is clamped with the clamping convex 123, so as to realize the detachable connection between the bottom shell 11 and the shell body 12. It can be understood that the clamping mode between the bottom shell 11 and the shell body 12 is not limited to the mode mentioned in this embodiment, but can also be in other modes.

[0044] In some embodiments, as shown in Figure 4 The surface of the bottom shell 11 away from the shell body 12 is provided with a plurality of protrusions 114, the height of the protrusion 114 is d1, the height of the probe group 30 exposed from the mounting port 102 of the bottom shell 11 is d2, and d1≥d2 is satisfied, so that under the action of the plurality of protrusions 114, the risk of the probe group 30 exposed from the mounting port 102 of the bottom shell 11 directly abutting the support surface (such as the ground) can be reduced.

[0045] In some embodiments, as shown in Figure 2 And Figure 5As shown, the circuit board 20 comprises a board body 21 and circuit elements, and the circuit elements are arranged on the board body 21. The board body 21 is provided with a notch 201, and the circuit elements comprise an inductor 22, the inductor 22 is connected to the board body 21 and arranged in the notch 201, and the inductor 22 is configured to extend along a direction perpendicular to the thickness direction of the shell 10. In other words, the inductor 22 is in a flat state relative to the circuit board 20, so that, compared with the mode that the inductor 22 is arranged vertically on the surface of the board body 21, the inductor 22 arranged flat relative to the board body 21 in the present application can reduce the space occupied by the inductor 22, and reduce the risk that the inductor 22 occupies too much space in the thickness direction of the shell 10, thereby causing the overall thickness of the alarm device 100 to become thicker. In the embodiment, the notch 201 is located on the side of the board body 21 close to the reminding mechanism 40.

[0046] As shown in the figures, Figure 2 As shown in the figures, Figure 5 As shown, the inductor 22 has at least two pins 221, at least one pin 221 is connected to a first surface 203 of the board body 21, and at least one pin 221 is connected to a second surface 204 of the board body 21, and the first surface 203 and the second surface 204 of the board body 21 are opposite surfaces. In this way, compared with the mode that the at least two pins 221 are connected to the same surface of the board body 21, it is beneficial to uniform force on the inductor 22, and reduces the risk of disconnection of the pins 221 of the inductor 22 from the board body 21. In the embodiment, the number of pins 221 of the inductor 22 is three, two pins 221 are connected to a surface of the board body 21 away from the bottom shell 11, and the other pin 221 is connected to another surface of the board body 21 close to the bottom shell 11. This arrangement is beneficial to enhancing the firmness of the connection between the pins 221 and the board body 21 during use, and reducing the risk of falling off of the solder joint at the connection between the pins 221 and the board body 21.

[0047] It should be understood that the board body 21 is provided with a circuit, such as an alarm circuit, a liquid detection circuit, etc. Since the present application does not involve improvement of the circuit on the board body 21, further description is not given here. The inductor 22 element includes other elements such as resistors, capacitors, etc., as long as they are required for the circuit, and are selected and arranged according to needs.

[0048] In some embodiments, as shown in the figures, Figures 3-4As shown, the probe set 30 includes at least two probe needles 31 and at least two conductive elastic sheets 32, each of the elastic sheets 32 is electrically connected to the circuit board 20, each of the probe needles 31 is mounted to the shell 10, one end of each of the probe needles 31 abuts against the elastic sheet 32, and the other end of each of the probe needles 31 is exposed outside the shell 10 through the mounting port 102. Thus, when the at least two probe needles 31 contact the liquid, the at least two probe needles 31 are conductively connected to each other through the liquid to form a loop, at which time the circuit board 20 will control the alert mechanism 40 to work. In the present embodiment, each of the probe sets 30 includes two probe needles 31 and two conductive elastic sheets 32.

[0049] In some embodiments, as Figures 3-4 shown, the number of the probe sets 30 is at least two, and at least one of the probe sets 30 is connected to one surface of the circuit board 20, and at least one of the probe sets 30 is connected to another surface of the circuit board 20. In the present embodiment, the number of the probe sets 30 is two, which are a first probe set 30a and a second probe set 30b, the mounting port 102 includes a first mounting port 102a and a second mounting port 102b, the first mounting port 102a and the second mounting port 102b are respectively located at opposite sides of the shell 10, the elastic sheet 32 of the first probe set 30a is connected to the first surface 203 of the circuit board 20, and the probe needles 31 of the first probe set 30a are exposed outside the shell 10 through the first mounting port 102a, the elastic sheet 32 of the second probe set 30b is connected to the other surface of the circuit board 20, and the probe needles 31 of the second probe set 30b are exposed outside the shell 10 through the second mounting port 102b.

[0050] For the convenience of description, as Figures 3-4 shown, the following description takes the mounting port 102 of the shell body 12 as the first mounting port 102a, and takes the mounting port 102 of the shell cover as the second mounting port 102b, the probe needles 31 of the first probe set 30a are exposed outside the shell body 12 through the first mounting port 102a, and the probe needles 31 of the second probe set 30b are exposed outside the shell cover through the second mounting port 102b. In the present embodiment, the end of the shell body 12 away from the shell cover is provided with a recessed area 1201, and the first mounting port 102a is located in the recessed area 1201. The first probe set 30a is exposed in the recessed area 1201 through the first mounting port 102a, which is conducive to the detection of whether the liquid drops in the recessed area 1201 by the first probe set 30a, and the detection can be performed without waiting for the water level of the liquid to rise to a predetermined height.

[0051] In use, the alarm device 100 is placed at a position where liquid leakage is to be detected, such as a faucet. When the faucet leaks and the liquid drips onto the concave area 1201 and contacts the probe 31 of the first probe set 30a, the concave area 1201 facilitates the liquid to gather and causes the probe 31 of the first probe set 30a to be conductive to form a loop, so that the alert mechanism 40 is activated to alert the user. The second probe set 30b can be used to detect whether the position where the alarm device 100 is placed has liquid leakage. When the liquid leakage rises to a predetermined liquid level and contacts the second probe set 30b close to the support surface (e.g. the ground), the probe 31 of the second probe set 30b is conductive to form a loop, so that the alert mechanism 40 is activated to alert the user, which is suitable for scenarios such as forgetting to turn off the faucet, valve or broken water pipe.

[0052] The alert mechanism 40 can be a buzzer, a status light, a combination of a buzzer and a status light, or other mechanisms, which can be selected according to the needs. For example, the alert mechanism 40 is a status light, which is connected to the circuit board 20 and can be connected to the housing 10 by adhesion, screwing or other means. When the probe set 30 detects liquid leakage, the status light connected to the circuit board 20 starts to flash or shine constantly to attract the user's attention, thereby achieving the purpose of alerting the user. For another example, the alert mechanism 40 is a buzzer, which is connected to the circuit board 20 and can be connected to the housing 10 by adhesion, screwing or other means. When the probe set 30 detects liquid leakage, the buzzer connected to the circuit board 20 starts to emit sound to alert the user of the liquid leakage. In the embodiment, the alert mechanism 40 is a buzzer, which is connected to the circuit board 20 and adhered to the housing body 12. The connecting line of the buzzer extends along one side of the board body 21 where the inductor 22 is arranged to be connected to the circuit board 20, which facilitates the management of the connecting line of the buzzer.

[0053] It can be understood that the alarm device 100 in the above embodiment can be powered internally through an external connecting line or directly powered by the battery assembly 50 that supplies current, which can be set according to the needs.

[0054] In some embodiments, as Figure 6As shown, the alarm device 100 also includes a battery assembly 50, which is housed within a receiving cavity 101 and connected to the housing 10. The battery assembly 50 is connected to both a circuit board 20 and an alert mechanism 40, with the circuit board 20 and the alert mechanism 40 located on the same side of the battery assembly 50. This allows the battery assembly 50 to supply current to both the circuit board 20 and the alert mechanism 40 without requiring additional power cables, offering convenience. In this embodiment, the circuit board 20 and the alert mechanism 40 are located on the same side of the battery assembly 50.

[0055] In some embodiments, such as Figure 2 and Figure 6 As shown, the battery assembly 50 includes a mounting bracket 51 and a battery 52. ​​The mounting bracket 51 is connected to the housing 10, and a mounting groove 501 is provided on the side of the mounting bracket 51 facing the housing cover for mounting the battery 52. ​​The mounting bracket 51 is partially stacked with the circuit board 20 along the thickness direction of the housing 10, meaning the circuit board 20 extends beyond the mounting bracket 51 in the first direction X. The receiving space formed between the end of the mounting bracket 51 and the circuit board 20 can accommodate some electrical components on the circuit board 20, which helps to fully utilize the space of the receiving cavity 101.

[0056] In some embodiments, such as Figure 5 and Figure 6 As shown, the alarm device 100 also includes an antenna 60, which is housed in the receiving cavity 101 and connected to the circuit board 20. The antenna 60 and the circuit board 20 are arranged side by side in the first direction X. The antenna 60 facilitates communication with the user's mobile device, allowing the user to be aware of the detection status of the probe group 30 and take timely measures.

[0057] In some embodiments, antenna 60 is a helical antenna 60, such as Figure 5 As shown, the helical antenna 60 includes a connecting section 61, a middle section 62, and a helical section 63 connected together. The connecting section 61 is connected to the circuit board 20. The helical section 63 extends helically in a direction perpendicular to the first direction X, and both sides of the helical section 63 abut against the circuit board 20 and the housing 10, thereby restricting the movement of the helical antenna 60 in the direction perpendicular to the first direction X. In this embodiment, the middle section 62 is L-shaped. The first end of the middle section 62 is connected to the connecting section 61, and the second end of the middle section 62 extends in a direction perpendicular to the first direction X (i.e., along a direction perpendicular to the first direction X). Figure 5 (Extending in the direction of the straight line L shown in the figure), compared to the scheme in which the spiral segment 63 extends on the first surface 203 or the second surface 204 of the plate 21, the arrangement of the spiral segment 63 in this scheme is beneficial to reduce the impact on the overall thickness and to reduce the thickness of the alarm device 100.

[0058] In some embodiments, please refer to Figure 3 The alarm device 100 further comprises a key assembly 70 connected with the circuit board 20 and the shell body 12 respectively, and the key assembly 70 is configured to control the working reminding mechanism 40 to stop working when subjected to an external force pressing towards the circuit board 20. In use, when the probe set 30 detects liquid, the circuit board 20 controls the reminding mechanism 40 to start working to remind the user that there is liquid leakage at present. The user presses the key assembly 70 after obtaining the reminder so that the circuit board 20 controls the reminding mechanism 40 to stop working.

[0059] In some embodiments, as shown in Figure 3 The key assembly 70 comprises a key cap 71 and a control key 72, the control key 72 is arranged on the circuit board 20, and the key cap 71 is arranged above the control key 72. The shell body 12 is provided with a key hole 701, and the key cap 71 is exposed outside the shell body 12 through the key hole 701. When the key cap 71 is pressed, the control key 72 located below the key cap 71 will be pressed to make the circuit on the circuit board 20 that controls the reminding mechanism 40 to stop working, thereby playing a role of canceling the reminder.

[0060] In some embodiments, as shown in Figure 3 The alarm device 100 further comprises a cap 80, the shell body 12 is provided with an opening 801, and the cap 80 is detachably connected with the shell body 12 and covers the opening 801. The space between the cap 80 and the shell body 10 constitutes a resonance cavity, which is conducive to amplifying the volume of the sound emitted by the buzzer and improving the user experience.

[0061] In use, the alarm device 100 selects liquid drop detection or liquid leakage detection according to the scene needs. For example, when liquid drop detection is needed, the alarm device 100 is arranged below an object (such as a faucet) for detecting whether liquid drops, and the recessed area 1201 is directed towards the object. When the object appears liquid drops, the dropped liquid drops to the recessed area 1201, so that the probe 31 located at the recessed area 1201 is turned on under the action of the dropped liquid, so that the reminding mechanism 40 works, and at the same time the circuit board 20 sends relevant information to the mobile terminal of the user far away through the antenna 60, which is convenient for the user to know in time. For another example, when liquid leakage detection is performed, the alarm device 100 is placed in the area to be detected. When the liquid level of the area rises due to liquid leakage or other factors (such as forgetting to turn off the faucet), the probe set 30 will be turned on under the action of the leaked liquid, so that the reminding mechanism 40 works to remind the user, and at the same time the circuit board 20 sends relevant information to the mobile terminal of the user far away through the antenna 60, which is convenient for the user to know in time.

[0062] The alarm device 100 provided by the embodiment of the present application comprises a shell 10, a circuit board 20, a probe set 30 and a reminding mechanism 40, the shell 10 is provided with a containing cavity 101 and a mounting port 102, the mounting port 102 is communicated with the containing cavity 101; the circuit board 20 is accommodated in the containing cavity 101; the probe set 30 is accommodated in the containing cavity 101 and is mounted in the mounting port 102, one end of the probe set 30 is connected with the circuit board 20, the other end of the probe set 30 is exposed outside the shell 10 through the mounting port 102; the reminding mechanism 40 is accommodated in the containing cavity 101, the reminding mechanism 40 is mounted in the shell 10 and is electrically connected with the circuit board 20, the reminding mechanism 40 and the circuit board 20 are arranged side by side in a first direction X, the first direction X is perpendicular to the thickness direction of the shell 10, the reminding mechanism 40 is configured to work when the probe set 30 detects liquid.
