Description

Technical Field

[0001] The utility model relates to the technical field of water purifiers, and in particular to a water leakage monitoring device for a water purifier. Background Art

[0002] With the development of science and technology and the improvement of people's living standards, the pursuit of quality of life is also growing, including the requirements for water quality. As an important water source in daily life, the development of tap water treatment and purification technology is particularly important. However, the leakage problem of water treatment equipment has always been difficult to avoid, especially for water purifiers that use tap water as a water source. Due to pipeline pressure, leakage incidents often occur during the use of water purifiers. Once leakage occurs, it will affect the service life of the water purifier and easily damage the user's indoor facilities.

[0003] However, the detection device for water purifier leakage in the prior art usually only uses a single detection technology to detect whether the water purifier is leaking. Although this method can detect water leakage, the detection accuracy is insufficient, and it is easy to misjudge that there is a leak in the water channel other than the water purifier, such as the sink, which will cause the water purifier to shut down and alarm, causing the user to blindly repair the water purifier, which not only increases the maintenance frequency and reduces the service life of the equipment, but also greatly reduces the user experience. Utility Model Content

[0004] To this end, the utility model proposes a water leakage monitoring device for a water purifier, aiming to improve the accuracy of water leakage monitoring of the water purifier.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions: a water leakage monitoring device for a water purifier, comprising a pressure detection module, a water leakage detection module, a switch detection module, an electrically controlled water inlet valve, an alarm module and a controller, wherein the pressure detection module is used to detect the pressure data of the water inlet pipeline, the pressure detection module is installed on the water inlet pipeline, the water leakage detection module is used to detect the water leakage state of the water purifier, the switch detection module is used to detect the switch state of the water purifier faucet, the electrically controlled water inlet valve is installed on the water inlet pipeline, the pressure detection module, the water leakage detection module and the switch detection module are all connected to the input end of the controller, and the electrically controlled water inlet valve and the alarm module are all connected to the output end of the controller.

[0006] Preferably, a water collecting trough is provided on the lower surface of the water purifier body, a diversion port is provided at a position on the lower surface of the water purifier body corresponding to the water collecting trough, the water leakage detection module is fixedly connected to the lower surface of the water purifier body, and the water leakage detection module is located in the water collecting trough.

[0007] Preferably, the water leakage detection module includes a leakage detection circuit board and two probes. The leakage detection circuit board is fixedly connected to the lower surface of the water purifier body. The leakage detection circuit board is located in the water collection tank and is arranged away from the diversion port. The probes are located below the leakage detection circuit board and are electrically connected to the leakage detection circuit board.

[0008] Preferably, the height of the probe is lower than the height between the bottom surface of the sump and the leak detection circuit board.

[0009] Preferably, one end of the electrically controlled water inlet valve is connected to the tap water pipe, and the other end is connected to the water inlet pipeline.

[0010] Preferably, the pressure detection module is installed at one end of the electric-controlled water inlet valve facing the water inlet pipeline.

[0011] Preferably, the switch detection module is connected to the switch handle of the water purification faucet, and the switch detection module is installed at one end of the switch handle of the water purification faucet away from the water inlet pipeline.

Once it is confirmed that the leakage is caused by internal factors of the machine, the electric control water inlet valve can be immediately controlled to close, the water source can be cut off, and the water can be prevented from continuing to lose water. At the same time, it can effectively prevent the machine from misjudging the existence of leakage in the water channel of the non-water purifier such as the sink, which causes the overall shutdown alarm of the water purifier, which improves the intelligence level of the water purifier to a certain extent, avoids unnecessary shutdown and frequent maintenance due to misjudgment, improves the accuracy of water leakage monitoring of the water purifier, and provides users with a more convenient and intelligent use experience.

[0019] The following is an explanation and description of the technical scheme of the embodiment of the utility model in conjunction with the drawings of the embodiment of the utility model, but the following embodiment is only a preferred embodiment of the utility model, not all. Based on the embodiment in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the utility model.

[0020] In the following description, terms such as "inside", "outside", "up", "down", "left", "right", etc. that indicate directions or positional relationships are only used to facilitate the description of the embodiments and simplify the description, and do not indicate or imply that the referred device or element must have a specific direction, be constructed and operated in a specific direction. Therefore, it should not be understood as a limitation on the present invention.

[0021] Before this specification describes a water purifier leakage monitoring device in detail in combination with one or more embodiments, the following aspects are first introduced about the common installation scenarios of water purifiers in households:

[0022] 1. Water source access: The water purifier needs to be connected to the household water source, usually by connecting the water inlet pipe 2 of the water purifier to the household tap water angle valve 3 (i.e., tap water pipe) to obtain tap water. During installation, it is necessary to ensure that the connection between the water source and the water inlet pipe 2 of the water purifier is tight to prevent water leakage.

[0023] 2. Spatial location: The water purifier body 1 needs to have enough space for installation to facilitate ventilation and heat dissipation of the machine, and also to facilitate daily maintenance and cleaning. Usually, the water purifier body 1 will be installed under the kitchen counter, in a storage room, near a sink, or on a wall.

[0024] 3. Water output: The water purifier needs to be connected to the household's water-using equipment. Usually, the water outlet pipe 4 of the water purifier is connected to one or more water purification taps 5 or direct drinking nozzles in the household. The water purified by the water purifier is output from the water purification tap 5 or direct drinking nozzle through the water outlet pipe 4 of the water purifier for direct drinking by family members or for daily cleaning, cooking, etc.

[0025] Please see attached Figure 1 , Figure 1 A schematic structural diagram of a water purifier leakage monitoring device provided by an embodiment of the present specification is shown.

[0026] like Figure 1 As shown, the water purifier leakage monitoring device may at least include a pressure detection module 7, a leakage detection module 8, a switch detection module 9, an electric-controlled water inlet valve 10, an alarm module and a controller 11. Among them:

[0027] The pressure detection module 7 is used to detect the pressure data of the water inlet pipeline 2. The pressure detection module 7 is installed on the water inlet pipeline 2. The water leakage detection module 8 is used to detect the water leakage state of the water purifier. The switch detection module 9 is used to detect the switch state of the water purifier faucet 5. The electric control water inlet valve 10 is installed on the water inlet pipeline 2 to realize the on and off of the water inlet pipeline 2 of the water purifier. The pressure detection module 7, the water leakage detection module 8 and the switch detection module 9 are all connected to the input end of the controller 11, and the electric control water inlet valve 10 and the alarm module are all connected to the output end of the controller 11.

[0028] The pressure data of the water inlet pipeline 2 refers to the pressure detection value at a certain position on the water inlet pipeline 2 of the water purifier. This embodiment does not limit the specific position where the pressure detection module 7 is installed on the water inlet pipeline 2. The electric control water inlet valve 10 can be installed at any position of the water inlet pipeline 2, as long as it can realize the on and off of the water inlet pipeline 2 of the water purifier, and this embodiment does not limit this.

[0029] Among them, the water leakage detection module 8 in this embodiment is a common water leakage protection device in the prior art for detecting the water leakage condition of the water purifier, such as being installed at the inner bottom inside the water purifier body 1, and the detection result of the water leakage state is usually leakage or no leakage.

[0030] Among them, the switch state of the water purification faucet 5 detected by the switch detection module 9 (such as: Hall switch, resistive switch, photoelectric sensor, etc.) refers to the open or closed state of the faucet or nozzle connected to the water outlet pipe 4 of the water purifier, that is, whether the water purified by the water purifier is in the use state of water output.

[0031] It is understandable that the water channel structure of the existing water purifier is limited by the spatial uncertainty and cost considerations of the tap water network terminal connection environment when connected to the external water channel, so the water purifier is not designed with an external water inlet valve when leaving the factory. For this reason, this embodiment installs an external electric-controlled water inlet valve 10 on the water inlet pipe 2 of the water purifier, and connects the electric-controlled water inlet valve 10 to the output end of the controller 11, providing a structural basis for the controller 11 to remotely cut off the water source after a water leak is detected.

[0032] Among them, the controller 11 in this embodiment can be integrated and installed on the control panel of the water purifier body 1, or a controller 11 can be independently set outside the water purifier body 1. It can be understood that the pressure detection module 7, the water leakage detection module 8 and the switch detection module 9 are all connected to the input end of the controller 11, and the electric control water inlet valve 10 and the alarm module are all connected to the output end of the controller 11, that is, the controller 11 stores a corresponding control program, which is generally an existing control program. By matching the pressure data of the water inlet pipeline 2 detected by the pressure detection module 7, the water leakage state of the water purifier detected by the water leakage detection module 8, and the switch state of the water purifier faucet 5 detected by the switch detection module 9 with the existing control program, the controller 11 can obtain the water leakage detection result, that is, whether the water purifier is currently in a water leakage state inside or outside, so as to timely control the closing of the electric control water inlet valve 10 and control the alarm module to send an alarm signal at the same time.

[0033] For example, the existing control program may be:

[0034] When the water outlet pipe 4 is disconnected, the leakage detection result is leakage, and the average pressure difference of the water inlet pipe 2 within 120 seconds is less than or equal to 2%, the matching corresponding leakage detection result is leakage due to non-machine internal factors, such as slight leakage at the connection between the faucet and the water outlet pipe 4, leakage in other pipes of the sink, leakage at the joint or sealing gasket at the water inlet end or the drainage end, etc.;

[0035] When the water outlet pipe 4 is disconnected, the water leakage detection result is leakage, and the average pressure difference of the water inlet pipe 2 within 120 seconds is greater than 2%, the matching corresponding leakage detection result is leakage due to internal factors of the machine;

[0036] When the leakage status detection result is no leakage and the faucet is in the open state, the average pressure difference of the water inlet pipe 2 within 3 seconds is greater than 20%, which means that the water flow in the water inlet pipe 2 can reach a larger pressure value for the water output of the faucet in a very short time, but the leakage status detection result is still no leakage, which can determine that the internal pipes of the machine are normal and there is no leakage.

[0037] Among them, the alarm module in this embodiment (not shown in the figure) includes but is not limited to speakers, LED lights, display screens, etc. arranged on or around the water purifier body 1. The alarm module sends out an alarm signal through sound, indicator lights or text indications on the display screen to inform the user that the water purifier is currently leaking inside or outside.

[0038] This embodiment combines the pressure detection module 7, the leakage detection module 8 and the switch detection module 9 to monitor the pressure change of the water inlet pipe 2, the leakage of the water purifier and the switch status of the water purifier faucet 5 in real time, comprehensively confirm whether the leakage detection result of the water purifier is a leakage caused by factors other than the internal factors of the machine or the internal factors of the machine, timely discover and distinguish the source of the leakage, which is helpful to quickly locate the real leakage of the water purifier and perform subsequent automatic control, that is, based on different leakage detection results, the on and off of the water inlet pipe 2 of the water purifier is controlled and a corresponding alarm signal is issued. Once it is confirmed that the leakage is caused by internal factors of the machine, the electronically controlled water inlet valve 10 can be immediately controlled to close, cut off the water source, and prevent water from continuing to lose. At the same time, it can effectively prevent the machine from misjudging the existence of leakage in the water channel other than the water purifier's internal water channel, such as the sink, which causes the overall shutdown alarm of the water purifier. To a certain extent, the intelligence level of the water purifier is improved, unnecessary shutdown and frequent maintenance due to misjudgment are avoided, the accuracy of water purifier leakage monitoring is improved, and a more convenient and intelligent use experience is provided for users.

[0039] In one embodiment of this specification, please refer to the attached Figure 2 A water collecting tank 801 is provided on the lower surface of the water purifier body 1, and a diversion port 802 is provided at a position on the lower surface of the water purifier body 1 corresponding to the water collecting tank 801. The water leakage detection module 8 is fixedly connected to the lower surface of the water purifier body 1, and the water leakage detection module 8 is located in the water collecting tank 801.

[0040] Among them, the water collection tank 801 in this embodiment can be designed to have a water collection area larger than the bottom surface of the water purifier body 1, or it can be designed to have a water collection area smaller than the bottom surface of the water purifier body 1. As long as the water collection effect can be achieved, the size of the water collection tank 801 is not limited.

[0041] It is understandable that the water leakage inside the water purifier can flow into the water collection tank 801 through the diversion port 802, and the water leakage outside the water purifier can also be collected at the diversion port 802 by gravity and then flow into the water collection tank 801. The water leakage detection module 8 is fixedly connected to the lower surface of the water purifier body 1, that is, the water leakage detection module 8 is installed on the outer bottom outside the water purifier body 1.

[0042] On the other hand, in this embodiment, the water leakage detection module 8 includes a leakage detection circuit board 803 and two probes 804. The leakage detection circuit board 803 is fixedly connected to the lower surface of the water purifier body 1. The leakage detection circuit board 803 is located in the water collection tank 801 and is set away from the guide port 802. The probe 804 is located below the leakage detection circuit board 803, and the probe 804 is electrically connected to the leakage detection circuit board 803.

[0043] It can be understood that the leakage detection circuit board 803 is fixedly connected to the lower surface of the water purifier body 1, that is, the leakage detection circuit board 803 is fixedly installed on the outer bottom of the water purifier body 1, and is set in the water collection range of the water collection tank 801 to avoid the guide port 802. The probe 804 is located below the leakage detection circuit board 803, and the probe 804 is electrically connected to the leakage detection circuit board 803, that is, when the water leakage of the water purifier is collected in the water collection tank 801, the two probes 804 are short-circuited and connected by the water in the water collection tank 801, and the leakage detection circuit board immediately obtains the short-circuit connection between the probes 804, and the leakage detection module 8 knows that there is a leakage in the current water purifier.

[0044] This embodiment can collect water leakage inside and outside the water purifier through the design of the water collection tank 801 and the diversion port 802. The water leakage detection module 8 is set at the outer bottom outside the water purifier body 1 and is set in the water collection tank 801. Regardless of whether the source of the water leakage is internal or external, the water leakage detection module 8 can promptly and effectively detect the short circuit of the probe 804, realize efficient water leakage monitoring, and simplify the internal structure of the water purifier at the same time. It is more convenient to repair and replace the water leakage detection module 8, and improve the adaptability and reliability of the water purifier. Since the leakage detection circuit board 803 and the probe 804 are both set away from the diversion port 802, false alarms caused by humidity or other factors that may exist near the diversion port 802 are reduced.

[0045] In one embodiment of this specification, please refer to the attached Figure 2 The height of the probe 804 is lower than the height between the bottom surface of the water collection tank 801 and the leakage detection circuit board 803.

[0046] By designing the height of the probe 804 to be slightly lower than the height between the bottom of the water collection tank 801 and the leak detection circuit board 803, it is possible to avoid the water leakage detection module 8 confirming the water leakage state of the water purifier as a leak due to a reasonable small amount of water accumulation, thereby affecting the subsequent controller 11's matching and confirmation of the specific leakage situation, which helps to improve the accuracy of the water leakage alarm to a certain extent.

[0047] In one embodiment of this specification, please refer to the attached Figure 1 One end of the electric-controlled water inlet valve 10 is connected to the tap water pipe, and the other end is connected to the water inlet pipeline 2.

[0048] On the other hand, in this embodiment, the pressure detection module 7 is installed at one end of the electric-controlled water inlet valve 10 facing the water inlet pipeline 2 .

[0049] This embodiment installs the pressure detection module 7 on the side of the water inlet pipe 2 of the electric-controlled water inlet valve 10, so that the pressure change of the water inlet pipe 2 can be monitored more directly. Since it is close to the water inlet source, it helps the pressure detection module 7 to detect any leakage of the water inlet pipe 2 in time, thereby reducing the damage caused by the leakage. At the same time, the integrated design of the pressure detection module 7 and the electric-controlled water inlet valve 10 in this embodiment can reduce the complexity of the water leakage detection device of the water purifier and improve the compactness and aesthetics of the overall equipment.

[0050] In one embodiment of this specification, please refer to the attached Figure 1 The switch detection module 9 is connected to the switch handle 6 of the water purification faucet, and the switch detection module 9 is installed at one end of the switch handle 6 of the water purification faucet away from the water inlet pipeline 2.

[0051] Placing the switch detection module 9 at the end of the switch handle away from the water inlet pipe 2 helps to reduce the impact of water flow fluctuations on the switch detection module 9 and improve the accuracy of detection.

[0052] In one embodiment of the present specification, the water leakage detection device of the water purifier includes a communication module, the communication module is connected to the output end of the controller 11, and the communication module is communicatively connected to the mobile end.

[0053] Among them, mobile terminals usually refer to the terminals of software applications or services that can be used on mobile devices, including but not limited to smartphones, tablets, smart watches and laptops. Mobile terminal software applications (i.e. Apps) are software designed for mobile device operating systems (such as iOS, Android, etc.). They use the characteristics of mobile devices, such as touch screens, location services, cameras and various sensors, to provide user interfaces and interactive experiences.

[0054] For example, the controller 11 can be connected to the App on the user's mobile phone through the communication module to realize remote reporting of water purifier leakage detection results, and send an alarm message to the user in a timely manner when the detection result is a leakage caused by internal factors of the machine.

[0055] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Those skilled in the art should understand that the utility model includes but is not limited to the contents described in the drawings and the above specific implementation. Any modification that does not deviate from the functional and structural principles of the utility model will be included in the scope of the claims.
