[0002] Most water immersion sensors on the market currently use simple electrodes or conductive films to achieve water immersion sensing. Although such designs can detect water immersion, they have shortcomings in the protection of the detection components. Water immersion sensors operate in humid environments, and if the detection components are in contact with liquid for a long time, corrosion, short circuits, or failures will occur, which will affect the accuracy and lifespan of the sensor. Utility Model Content

[0003] This application provides a water immersion sensor to address the problem that prolonged contact between the sensor's detection components and liquid affects the sensor's accuracy and lifespan.

[0004] To achieve the above objectives, this utility model provides a water immersion sensor, which includes a front shell, a rear shell, a main board, a waterproof component, and a detection component: the main board is installed in the cavity formed by the front and rear shells being joined together; one end of the detection component is connected to the main board, and the other end extends out of the cavity through an opening in the rear shell, wherein: the waterproof component is used to fill the gap after the front and rear shells are joined together; the detection component is used to send a valid signal to the main board when it comes into contact with liquid; the main board is used to determine whether a water immersion accident has occurred based on the valid signal sent by the detection component.

[0005] As can be seen, in this embodiment of the application, by filling the gap after the front and rear shells are joined by the waterproof component, the contact between the detection component of the water immersion sensor in the internal cavity and the humid air is isolated, the contact between the detection component and the liquid is reduced, and the problems of corrosion, short circuit or failure of the sensor in the internal cavity are avoided, thereby improving the accuracy and service life of the sensor.

[0006] In one possible embodiment, a protective component is provided between the motherboard and the probe component, the protective component being used to fill the gap between the opening in the back cover and the probe component.

[0008] In one possible embodiment, the protection component includes a conductive channel through which the detection component is connected to the motherboard.

[0009] In one possible embodiment, the protective component is a detachable protective component.

[0010] As can be seen from the embodiments of this application, the protection component can be replaced in a timely manner based on the actual wear and tear, thereby improving the service life of the water immersion sensor.

[0011] In one possible embodiment, the water immersion sensor also includes a power supply, and the motherboard is further configured to control the power supply to power the detection component at preset intervals, and to acquire signals sent by the detection component at preset intervals.

[0012] As can be seen, in this embodiment, intermittent detection is used to reduce the power-on time of the detection component, thereby slowing down the wear and tear process such as rusting and corrosion caused by continuous current conduction on the detection component, and improving the service life of the water immersion sensor.

[0013] In one possible embodiment, the detection component is a retractable detection component; the motherboard is also used to control the retractable detection component to retract into the cavity provided that a valid signal is obtained.

[0014] As can be seen in this embodiment, under the premise of obtaining a valid signal, by controlling the retractable detection component to retract into the cavity, the detection component is prevented from being immersed in liquid for a long time in the event of a water immersion accident, thus slowing down the wear and tear process caused by liquid immersion, such as rusting and corrosion, and further improving the service life of the water immersion sensor.

[0015] In one possible embodiment, the motherboard is used to determine whether a water immersion accident has occurred based on a valid signal sent by the detection component, including: the motherboard is further used to control the power supply to continuously supply power to the detection component while controlling the retractable detection component to retract into the cavity, and to continuously acquire the signal sent by the detection component; if the valid signal is interrupted, it is determined that a water immersion accident has occurred; if the valid signal is not interrupted, it is determined that no water immersion accident has occurred.

[0016] As can be seen, in this embodiment, intermittent detection is used to reduce the power-on time of the detection component, thereby slowing down the wear and tear process such as rusting and corrosion caused by continuous current conduction on the detection component, and improving the service life of the water immersion sensor.

[0017] In one possible embodiment, the connection points on the motherboard to the probe components are surrounded by a ground plane.

[0019] In one possible embodiment, the paved ground is also provided with a triangular-shaped static discharge component.

[0020] As can be seen from the embodiments of this application, by setting a triangular electrostatic discharge component on the paved ground, electrostatic discharge can be carried out in a timely manner, which further improves the service life of the water immersion sensor.

[0021] In one possible embodiment, the motherboard further includes an alarm component and a communication component; the motherboard is also configured to generate alarm information upon determining that a water immersion accident has occurred, and control the alarm component to issue an audible alarm based on the alarm information; and control the communication component to send the alarm information.

[0022] As can be seen from the embodiments of this application, the alarm component and the communication component can simultaneously provide an audible alarm based on the alarm information and send an alarm message through the communication component when a water immersion accident occurs, thereby increasing the alarm channels of the water immersion sensor and improving the reliability of the water immersion sensor.

[0035] Example 1:

[0036] Please see Figure 1 , Figure 1 This is a schematic diagram of a water immersion sensor provided in an embodiment of this application. The water immersion sensor 100 includes a front shell 101, a rear shell 102, a main board 103, a waterproof component 104, and a detection component 105. The main board 103 is installed in the cavity formed by the front shell 101 and the rear shell 102 when they are joined together. One end of the detection component 105 is connected to the main board 103, and the other end extends out of the cavity through an opening in the rear shell 102.

[0037] Waterproof component 104 is used to fill the gap after the front shell 101 and the rear shell 102 are joined together;

[0038] The detection component 105 is used to send a valid signal to the main board 103 when it comes into contact with liquid;

[0039] The motherboard 103 is used to determine whether a water immersion accident has occurred based on the valid signal sent by the detection component 105.

[0040] Specifically, in this embodiment, the mainboard 103 of the water immersion sensor 100 is installed in the cavity formed by the front shell 101 and the rear shell 102 after they are joined together. It should be noted that... Figure 1 The front shell 101 and rear shell 102 shown are disc-shaped structures only as examples. This embodiment does not limit the shape of the front shell 101 and rear shell 102. For example, they can also be spherical, cuboid, or other shapes.

[0041] The motherboard 103 is connected to one end of the detection component 105, and the other end of the detection component 105 extends out of the cavity through an opening on the rear shell 102 (the detection component 105 is specifically a detection electrode or a conductive film) to contact the liquid outside the cavity. When it comes into contact with the liquid, it sends a valid signal to the motherboard 103. For example, it sends a high-level signal (invalid signal) to the motherboard 103 when it does not come into contact with the liquid. After the detection component 105 comes into contact with the liquid, it sends a low-level signal (valid signal) to the motherboard 103.

[0042] The motherboard 103 receives the signal from the detection component 105, and performs amplification, filtering and other processing, and then determines whether a water immersion accident has occurred based on the processed signal.

[0043] The determination of whether a flooding accident has occurred based on the signal specifically includes determining whether a flooding accident has occurred based on the characteristics of the signal, such as the signal value and signal duration. For example, if the signal value is within the valid number range and the signal duration is within the valid time range, then it is determined that a flooding accident has occurred.

[0044] The waterproof component 104 is specifically made of insulating and waterproof material (such as rubber, silicone and plastic) to fill the gap formed after the front shell 101 and the rear shell 102 are closed, so as to isolate the cavity from the outside world and prevent liquid and humid air from entering the cavity.

[0045] also, Figure 1 The configuration shown includes four detection components 105. The motherboard 103 can determine whether a water immersion accident has occurred based on a valid signal sent by any one of the detection components 105. That is, as long as a valid signal from any one of the detection components 105 indicates that a water immersion accident has occurred, the motherboard 103 will determine that a water immersion accident has occurred, thereby improving the detection accuracy of the water immersion sensor 100. The number of four detection components 105 shown here is only an example; in actual applications, there may be more or fewer detection components 105.

[0046] As can be seen from the embodiments of this application, by filling the gap after the front and rear shells are joined by the waterproof component, the contact between the detection component of the water immersion sensor in the internal cavity and the humid air is isolated, the contact time between the detection component and the liquid is reduced, and the problems of corrosion, short circuit or failure of the sensor in the internal cavity are avoided, thereby improving the accuracy and service life of the sensor.

[0047] Optionally, a protective component is provided between the motherboard and the detection component, which is used to fill the gap between the opening in the back cover and the detection component.

[0048] Specifically, in this example, a protective component is provided between the motherboard and the detection component. The protective component is made of the same or similar waterproof and insulating material as the waterproof component. The protective component is specifically a component in the form of a rubber ring or a baffle, which is installed between the motherboard and the detection component.

[0049] Furthermore, the protective component also serves to enclose the portion of the probe component within the cavity. See also... Figure 2 , Figure 2 The diagram shows a protective component provided in an embodiment of this application. As can be seen, the protective component is disposed between the motherboard and the detection component, filling the gap between the opening of the back cover and the detection component, further isolating the cavity from the external environment and enhancing the airtightness of the cavity.

[0050] As can be seen, in this embodiment of the application, by setting a protective component between the motherboard and the detector component to fill the gap between the opening of the back cover and the detector component, the sealing performance of the cavity is improved, and the contact between the detector component and the liquid is further reduced.

[0051] Optionally, the protection component includes a conductive channel through which the detection component is connected to the motherboard.

[0052] Specifically, the protection component has a conductive channel inside, which protects the detection component and ensures that the signal between the detection component and the motherboard can be transmitted normally.

[0053] Optionally, the protective component is a removable protective component.

[0054] Specifically, the protection component here is a detachable component, allowing users to replace it promptly based on its wear and tear to ensure the airtightness of the water immersion sensor's cavity. The protection component is fixed to the motherboard or rear cover via a fixing structure, such as clips or threads.

[0055] For example, please see Figure 3 , Figure 3 This is a schematic diagram of another protective component provided in an embodiment of this application, wherein the protective component is a frustum assembly with an internal conductive channel, and the protective component is made of an insulating and waterproof elastic material.

[0056] The protective component is fixed to the motherboard by a mounting structure, and conductive channels are used to connect and communicate between the detection component and the motherboard. The frustum shape allows the protective component to effectively fill the gap between the rear housing opening and the detection component, further improving the cavity's sealing and reducing the contact between the detection component and liquid within the cavity.

[0057] As can be seen from the embodiments of this application, the protection component can be replaced in a timely manner based on the actual wear and tear, thereby improving the service life of the water immersion sensor.

[0058] Optionally, the connection points on the motherboard to the detection component are surrounded by a ground plane.

[0059] The connection points of the probe components on the motherboard are surrounded by ground planes. Ground planes can prevent power creep to other I / O ports on the motherboard and damage the motherboard.

[0060] As can be seen from the embodiments of this application, by surrounding the connection points of the motherboard with grounding, it is possible to prevent creepage to other I / O ports on the motherboard and damage the motherboard, thereby improving the service life of the water immersion sensor.

[0061] Optionally, the paved surface is also provided with a triangular-shaped static discharge component.

[0062] Specifically, please see Figure 4 , Figure 4 The schematic diagram of a motherboard provided in this application embodiment shows that the connection points on the motherboard are surrounded by a ground plane. Some triangular electrostatic discharge components with windows on the ground plane increase the electrostatic discharge channel. When static electricity is generated, the static electricity can be discharged through the ground plane and the electrostatic discharge components, avoiding damage to other components on the motherboard.

[0063] Furthermore, protective components such as electrostatic discharge tubes are also included at the connection point to further improve the efficiency and effectiveness of electrostatic discharge.

[0064] As can be seen from the embodiments of this application, by setting a triangular electrostatic discharge component on the paved ground, electrostatic discharge can be carried out in a timely manner, which further improves the service life of the water immersion sensor.

[0065] Example 2:

[0066] The above embodiment 1 provides a water immersion sensor for a motherboard to determine whether a water immersion accident has occurred based on the signal of a detection component. Based on this, and assuming that the detection component has an independent power supply, this application embodiment also provides a more detailed water immersion sensor.

[0067] In this embodiment, the water immersion sensor includes a front shell, a rear shell, a motherboard, a waterproof component, and a detection component. The motherboard is installed within the cavity formed by the front and rear shells being joined together; one end of the detection component is connected to the motherboard, and the other end extends out of the cavity through an opening in the rear shell, wherein:

[0068] Waterproof components are used to fill the gaps after the front and rear shells are joined together;

[0069] The detection component is used to send a valid signal to the motherboard upon contact with the liquid.

[0070] The motherboard is used to determine whether a water immersion accident has occurred based on valid signals sent by the detection components.

[0071] For detailed descriptions of the front shell, rear shell, waterproof components, and detection components, please refer to the relevant descriptions in Embodiment 1, which will not be repeated here.

[0072] The water immersion sensor also includes a power supply and a motherboard, which control the power supply to the detection component at preset time intervals, such as every 30s, 60s, 180s, etc., so that the detection component can detect liquid and send a valid signal to the motherboard when liquid is detected.

[0073] While the motherboard controls the power supply to the detection component at preset time intervals, the motherboard will also acquire signals sent by the detection component at preset time intervals. Furthermore, each power supply from the motherboard lasts for a first preset duration (e.g., 5 seconds, 10 seconds, etc.).

[0074] The motherboard here acquires the signals sent by the detection component at preset intervals. Specifically, while the motherboard supplies power to the detection component, it also acquires the signals sent by the detection component and determines whether a water immersion accident has occurred in the environment where the detection component is located based on whether the signals sent by the detection component are valid.

[0075] In summary, the detection component will only be powered on and send signals to the motherboard if the motherboard control power supply provides power to the detection component.

[0076] In addition, it should be noted that the motherboard here can also be powered by a power supply, or the motherboard can be powered by another independent power supply. The motherboard can switch between power supply and power off states at preset intervals based on the power supply or independent power supply, or switch between power supply and sleep states at preset intervals.

[0077] In other words, when the detection component is powered on, the motherboard is also powered on; when the detection component is powered off, the motherboard is either powered on or in hibernation mode.

[0078] For details, please see Figure 5 , Figure 5 The present application provides a schematic diagram of a detector circuit, which includes a positive detection electrode P+, ​​a negative detection electrode P-, and a transistor Q. The signal sent by the detector to the motherboard is a level signal.

[0079] The positive probe electrode P+ and the negative probe electrode P- each include at least one conductive contact extending out of the cavity, such as a rivet.

[0080] It can be seen that when the power supply supplies power to the detector, if neither the positive detection electrode P+ nor the negative detection electrode P- comes into contact with the liquid, it is equivalent to the positive detection electrode P+ and the negative detection electrode P- being disconnected. The signal sent by the detector circuit to the motherboard is an invalid signal, i.e., a high-level signal. If the positive detection electrode P+ and the negative detection electrode P- detect the liquid, it is equivalent to the positive detection electrode P+ and the negative detection electrode P- having a weak electrical conduction, providing the base voltage to the transistor Q, thereby triggering the collector and emitter of the transistor Q to conduct. According to the principle of level equivalence, the signal sent by the detector circuit to the motherboard is a valid signal, i.e., a low-level signal.

[0081] Furthermore, the positive and negative detector electrodes each include multiple sub-detector electrodes. When any one of the sub-detector electrodes in the positive and negative detector electrodes is turned on, the detector circuit sends a low-level signal to the motherboard; otherwise, the detector circuit sends a high-level signal to the motherboard.

[0082] As can be seen, by configuring multiple sub-detection electrodes on both the positive and negative detection electrodes, the water immersion sensor can operate normally as long as any pair of sub-detection electrodes can conduct normally, thereby improving the reliability of the water immersion sensor.

[0083] As can be seen, in this embodiment, intermittent detection is used to reduce the power-on time of the detection component, thereby slowing down the wear and tear process such as rusting and corrosion caused by continuous current conduction on the detection component, and improving the service life of the water immersion sensor.

[0084] Optionally, the detection component is a retractable detection component; the motherboard is also used to control the retractable detection component to retract into the cavity, provided that a valid signal is obtained.

[0085] Specifically, in this embodiment, the detection component is a retractable detection component. The detection component achieves retraction and extension through gears, hydraulic rods, springs, etc., so that the retractable component can achieve the retraction and extension function under the control of the motherboard.

[0086] For example, please see Figure 6 , Figure 6This is a schematic diagram of a retractable detection component provided in an embodiment of this application. As can be seen, the detection component includes a telescopic structure for achieving telescopic extension and retraction. The telescopic structure extends the detection component out of the cavity or retracts it into the cavity based on the control of the motherboard.

[0087] Based on the above, it can be seen that a valid signal is sent to the motherboard only when the detection component is in operation and has detected liquid. Therefore, to prevent the detection component from being immersed in liquid for an extended period, the motherboard, upon receiving a valid signal, controls the retractable detection component to retract into the cavity, thus avoiding prolonged immersion in liquid.

[0088] As can be seen in this embodiment, under the premise of obtaining a valid signal, by controlling the retractable detection component to retract into the cavity, the detection component is prevented from being immersed in liquid for a long time in the event of a water immersion accident, thus slowing down the wear and tear process caused by liquid immersion, such as rusting and corrosion, and further improving the service life of the water immersion sensor.

[0089] Optionally, the motherboard is used to determine whether a water immersion accident has occurred based on the valid signal sent by the detection component, including: the motherboard is also used to control the power supply to continuously supply power to the detection component while controlling the retractable detection component to retract into the cavity, and to continuously acquire the signal sent by the detection component; if the valid signal is interrupted, it is determined that a water immersion accident has occurred; if the valid signal is not interrupted, it is determined that no water immersion accident has occurred.

[0090] It should be noted that after the end of the detection component protruding from the cavity comes into contact with liquid, the detection component will send a valid signal to the main board. Reasons for contact with liquid include a water immersion incident in the detection environment, liquid adhering to the detection component, or even excessively high humidity in the detection environment. Therefore, the main board needs to further verify whether the valid signal is due to a genuine water immersion incident in the detection environment or other reasons.

[0091] In this embodiment, the motherboard specifically uses a scalable detection component and a power supply to determine whether a water immersion accident has occurred in the current tested environment.

[0092] Under the premise that the motherboard controls the retractable detection component to retract into the cavity, that is, after the detection component detects the liquid and sends a valid signal to the motherboard, the motherboard controls the retractable detection component to retract into the cavity. During the retraction process, the retractable detection component needs to remain powered on, so the motherboard also controls the power supply to continuously supply power to the detection component.

[0093] During the process of controlling the retractable probe component to retract into the cavity, the motherboard will continuously acquire the signals sent by the probe component and determine whether a water immersion accident has occurred in the tested environment based on whether the valid signal is interrupted at this time.

[0094] If a water immersion accident occurs in the tested environment, during the process of the retractable probe extending into the cavity, the retractable probe will detach from the liquid environment and will no longer be able to send a valid signal to the motherboard. This will result in the interruption of the valid signal. Therefore, if the retractable probe is controlled to retract into the cavity, the valid signal will be interrupted in the signals continuously acquired by the motherboard after the retractable probe leaves the liquid. Thus, the motherboard determines that a water immersion accident has occurred.

[0095] If no water immersion accident occurs in the tested environment, the valid signal sent by the retractable detection component to the motherboard may be due to excessive air humidity. In this case, after the retractable component extends and retracts into the cavity according to the control of the motherboard, it will continue to send a valid signal to the motherboard. Therefore, the motherboard judges that no water immersion accident has occurred.

[0096] In addition, it should be noted that the expansion and contraction speed of the retractable component is greater than the possible water level rise rate in the tested environment, in order to avoid the retractable detection component expanding and contracting at a speed less than the water level rise rate, which could lead to a misjudgment by the motherboard.

[0097] Furthermore, after the motherboard determines whether a water immersion accident has occurred or not, the motherboard will, after a second preset time interval, control the retractable component to extend out of the cavity, and control the power supply to the detection component again according to the preset time interval, and acquire the signal sent by the detection component according to the preset time interval.

[0098] As can be seen, in this embodiment of the application, after the retractable detection component sends a valid signal for the first time, the motherboard controls the retractable detection component to retract into the cavity, and continuously acquires the signal sent by the detection component during the retraction process. This allows the system to determine whether a water immersion accident has occurred based on whether the valid signal is interrupted, thereby improving the accuracy of the water immersion sensor.

[0099] Example 3:

[0100] The above-mentioned embodiment 1 provides a water immersion sensor for a motherboard to determine whether a water immersion accident has occurred based on the signal of a detection component. Based on this, and assuming that the motherboard includes an alarm component and a communication component, this embodiment of the application also provides a more detailed water immersion sensor.

[0101] In this embodiment, the water immersion sensor includes a front shell, a rear shell, a motherboard, a waterproof component, and a detection component. The motherboard is installed within the cavity formed by the front and rear shells being joined together; one end of the detection component is connected to the motherboard, and the other end extends out of the cavity through an opening in the rear shell, wherein:

[0102] Waterproof components are used to fill the gaps after the front and rear shells are joined together.

[0103] The detection component is used to send a valid signal to the motherboard when it comes into contact with liquid.

[0104] The motherboard is used to determine whether a water immersion accident has occurred based on valid signals sent by the detection components.

[0105] For detailed descriptions of the front shell, rear shell, waterproof components, and detection components, please refer to the relevant descriptions in Embodiment 1, which will not be repeated here.

[0106] It should be noted that the motherboard also includes an alarm component and a communication component; the motherboard is also used to generate alarm information when a water flooding accident is determined to have occurred, and to control the alarm component to issue an audible alarm based on the alarm information; and to control the communication component to send the alarm information.

[0107] Specifically, this application embodiment mainly focuses on describing the features of the motherboard; please refer to [link / reference]. Figure 7 , Figure 7 This is a schematic diagram of the internal structure of a motherboard provided in an embodiment of this application, including a controller, an interface, an alarm component, and a communication component.

[0108] The interface is used to connect to components such as the detection component and the power supply, and to convert the analog signals sent by the detection component into digital signals and send control signals to the detection component, the power supply and other components.

[0109] The controller is used to control components such as the detection unit and power supply, and to determine whether a water immersion accident has occurred based on the digital signals obtained from the interface conversion.

[0110] After confirming that a flooding incident has occurred, the controller is also used to generate alarm information and control the alarm component to issue an audible alarm based on the alarm information; and to control the communication component to send the alarm information.

[0111] The alarm information here may include the time of the flooding incident, the degree of danger of the flooding incident, etc. The alarm component is a speaker. The mainboard controls the alarm component to produce an audible alarm according to the alarm information through the controller in the mainboard, so as to transmit the alarm information to people near the flood sensor.

[0112] Furthermore, if the alarm components here also include alarm lights, the controller in the motherboard is also used to control the alarm components to implement light alarms.

[0113] Specifically, the communication component here sends alarm information to the user terminal or server connected to the communication component. The user can receive the alarm information through server notifications or applications on the user terminal.

[0114] Optionally, the motherboard is also used to periodically send detection signals to the detection component. If no feedback signal is received within a third preset time period, the detection component is judged to be faulty and fault information is generated, and the communication component is controlled to send the fault information.

[0115] As can be seen from the embodiments of this application, the alarm component and the communication component can simultaneously provide an audible alarm based on the alarm information and send an alarm message through the communication component when a water immersion accident occurs, thereby increasing the alarm channels of the water immersion sensor and improving the reliability of the water immersion sensor.

[0116] As can be seen from the water immersion sensor in the above-described embodiments, the waterproof and protective components reduce the contact between the internal structure of the water immersion sensor and the liquid, thereby improving the accuracy and lifespan of the sensor. The removable protective component allows for timely replacement, further extending the lifespan of the water immersion sensor. The use of intermittent detection and a retractable detection component mitigates the wear and tear caused by continuous current conduction, such as rusting and corrosion. Static electricity discharge is achieved through a grounding and electrostatic discharge component, and multiple alarm triggers are implemented through alarm and communication components, improving the reliability of the water immersion sensor.

[0117] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions of other embodiments.
