Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, and in particular to an intelligent water immersion sensor. Background Technology

[0002] A water immersion sensor is a sensor that detects whether water leakage has occurred within the measured area. Once leakage is detected, it immediately issues an alarm to prevent related losses and damages. Based on the principle of liquid conductivity, the water immersion sensor uses electrodes to detect the presence of water and then converts the result into a dry contact output. Water immersion sensors are widely used in data centers, communication equipment rooms, power plants, warehouses, archives, and any other location requiring waterproofing.

[0003] However, existing water immersion sensors have limited detection range, typically only able to detect the presence of water on one side or one end of the sensor. This limits the applicable environment of the water immersion sensor and hinders its versatility. In addition, some existing water immersion sensors also suffer from poor intelligence and weak alarm sounds. Utility Model Content

[0036] like Figure 1-5 The intelligent water immersion sensor shown includes a housing 1, a main board 2, probes 3, and a detection plate 4. The main board 2 is disposed inside the housing 1. There are two sets of probes 3, which are respectively disposed at both ends of the bottom surface of the housing 1. The upper end of the probe 3 is electrically connected to the main board 2, and the lower end of the probe 3 extends out of the bottom surface of the housing 1. The detection plate 4 is disposed at one end of the top surface of the housing 1. The lower end of the detection plate 4 is electrically connected to the main board 2, and the upper end of the detection plate 4 extends out of the top surface of the housing 1. It should be noted that there are four probes 3, arranged in pairs. In each pair, one probe 3 is the positive terminal and the other is the negative terminal. Normally, the two probes 3 are insulated from the air. When submerged in water, the probes 3 become conductive, and the sensor outputs a dry contact signal, causing the sensor to issue an alarm. Similarly, there are two detection pieces 4, one positive and the other negative. They are connected when submerged in water, and the sensor will issue an alarm when either pair of probes 3 or detection pieces 4 becomes conductive. In addition, the mainboard 2 is equipped with a wireless communication module (which can be a WiFi module or a Bluetooth module) to enable the water immersion sensor to connect wirelessly to a mobile phone. This allows users to check the working status of the water immersion sensor on their mobile phones and remotely check whether the water immersion sensor has issued an alarm, providing great convenience to users.

[0037] The beneficial effects of this utility model are as follows: by setting probes 3 at both ends of the bottom surface of the housing 1 and setting a detection piece 4 on the top surface of the housing 1, the water immersion sensor can detect two directions at the same time, thereby improving the detection range of the water immersion sensor and improving its practicality.

[0038] Please refer to Figure 4 and Figure 5In one possible implementation, the top of the housing 1 is provided with a first limiting part 111 through which the detection piece 4 passes, and the bottom of the housing 1 is provided with a second limiting part 121 through which the probe 3 passes. It should be noted that both the first limiting part 111 and the second limiting part 121 have through holes for the detection piece 4 and the probe 3 to pass through, and are sealed. The first limiting part 111 can limit the detection piece 4, and the second limiting part 121 can limit the probe 3, which helps to improve the stability of the detection piece 4 and the probe 3.

[0039] Please refer to Figure 1 and Figure 3 In one possible implementation, the top of the housing 1 is provided with a panel 5, and the panel 5 is provided with a button 6, which is connected to the main board 2. It should be noted that the panel 5 is fixed to the housing 1 by bolts, the button 6 is snapped to the housing 1, and the main board 2 is provided with a switch, with the button 6 corresponding to the switch. When the user presses the button 6, the switch can be triggered to start or stop the water immersion sensor.

[0040] Please refer to Figure 3 In one possible implementation, the motherboard 2 is equipped with a speaker, and the top of the housing 1 is provided with a sound outlet channel 112 corresponding to the speaker. A sound amplification cavity 13 is formed between the panel 5 and the housing 1, and the sound outlet channel 112 communicates with the sound amplification cavity 13. The panel 5 has sound outlets 51 on both sides. It should be noted that the speaker is used to emit an alarm sound, and the speaker can be a buzzer. Specifically, the top of the housing 1 has a circular groove, and the sound outlet channel 112 is located in the center of the groove. A ring is provided on the lower surface of the panel 5, and the ring extends into the groove. The top end of the sound outlet channel 112 extends into the ring. The panel 5 covers the groove to form the sound amplification cavity 13. The sound outlets 51 on both sides of the panel 5 communicate with the sound amplification cavity 13. The sound emitted by the speaker enters the sound amplification cavity 13 through the sound outlet channel 112. The sound resonates in the sound amplification cavity 13 to achieve the amplification effect, and then is emitted to the outside from the sound outlets 51.

[0041] Please refer to Figure 3 and Figure 4 In one possible implementation, the housing 1 includes an upper housing 11 and a lower housing 12. A stud 114 is provided on the inner wall of the upper housing 11, and a threaded hole corresponding to the stud 114 is provided on the lower housing 12. The upper housing 11 and the lower housing 12 are bolted together. It should be noted that the mainboard 2 has a through hole corresponding to the stud 114. By inserting a bolt through the threaded hole in the lower housing 12 and threading it through the mainboard 2 to the stud 114, a fixed connection between the upper housing 11 and the lower housing 12 is achieved, simultaneously securing the mainboard 2 and improving its stability.

[0042] Please refer to Figure 3 and Figure 4In one possible implementation, the lower shell 12 is provided with a positioning post 122, and the inner wall of the upper shell 11 is provided with a positioning hole 113, into which the positioning post 122 is inserted. It should be noted that the positioning post 122 cooperates with the positioning hole 113 to achieve rapid positioning of the upper shell 11 and the lower shell 12, improving assembly efficiency. Furthermore, the motherboard 2 is provided with a through hole for the positioning post 122 to pass through, and the corner of the motherboard 2 is fitted onto the positioning post 122 to simultaneously position the motherboard 2.

[0043] Please refer to Figure 3 In one possible implementation, a first sealing ring 7 is also included. A first limiting groove 123 is provided on the lower shell 12, and the first sealing ring 7 is disposed within the first limiting groove 123. The upper surface of the first sealing ring 7 abuts against the upper shell 11, and the lower surface of the first sealing ring 7 abuts against the lower shell 12. It should be noted that the first limiting groove 123 can limit the position of the first sealing ring 7, thereby improving its stability. The first sealing ring 7 can be made of silicone material. The first sealing ring 7 can seal the gap between the upper shell 11 and the lower shell 12, which helps to improve the sensor's sealing performance.

[0044] Please refer to Figure 3 In one possible implementation, a battery compartment 124 is provided at the bottom of the housing 1, which is used to house the battery. It should be noted that the battery compartment 124 is located on the lower housing 12, and the upper end of the battery compartment 124 is covered by the motherboard 2. The battery is electrically connected to the motherboard 2 and is used to power the sensor.

[0045] Please refer to Figure 3 In one possible implementation, a battery cover 14 is also included. The battery cover 14 is connected to the bottom of the housing 1 and covers the battery compartment 124. It should be noted that the battery needs to be replaced regularly to ensure that the sensor has sufficient power and can operate stably. The battery cover 14 is bolted to the lower housing 12. When replacing the battery, simply remove the battery cover 14 and then replace the battery, which is very convenient. In addition, a support portion 141 is provided on the inner wall of the battery cover 14. The support portion 141 is wavy and is used to support the battery.

[0046] Please refer to Figure 3 and Figure 5In one possible implementation, a second sealing ring 8 is also included. A second limiting groove 125 is provided at the bottom of the housing 1, and the second sealing ring 8 is disposed within the second limiting groove 125. The battery cover 14 is also disposed within the second limiting groove 125, with the second sealing ring 8 located between the housing 1 and the battery cover 14. It should be noted that the second limiting groove 125 can limit the second sealing ring 8 to improve its stability. The second sealing ring 8 can be made of silicone. It can seal the gap between the battery cover 14 and the lower housing 12. Furthermore, the second sealing ring 8 has a through hole for bolts to pass through. The bolts connecting the battery cover 14 and the lower housing 12 pass through the through hole, preventing liquid from entering the housing 1 along the bolts and further improving the sensor's sealing performance.
