[0002] Mechanical water meters, which record water consumption through the rotation of mechanical components, are widely used in the current market. While simple in structure, these meters require manual reading, making real-time monitoring of water consumption difficult.

DETAILED DESCRIPTION

[0044] In order for those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor should fall within the scope of protection of the present application.

[0045] As Figures 1-7As shown, an electronic Internet of Things water meter in an embodiment of the present application is described by taking a water heater applied in a hot water room of a university dormitory as an example, which comprises a meter body 10 and an electronic communication meter box 20, and the electronic communication meter box 20 is fixedly installed on the meter body 10. The electronic communication meter box 20 is sequentially provided with a digital display screen 22, an operation button 23, a card insertion port 24, a code scanning area 25 and a mechanical dial 26, wherein the digital display screen 22 is used to display temperature, water quantity, water fee, balance and other parameters, so as to intuitively obtain various parameter data. The operation button 23 includes but is not limited to a water temperature adjusting button, a water quantity adjusting button and a start-stop button, and students can control the water temperature, water quantity and water start-stop through the operation button 23.

[0046] The card insertion port 24 can identify an IC card, and students can take the card to insert the card to take water, which is convenient for transaction. Students can also scan the code scanning area 25 through a mobile phone APP to log in the system, so as to control the water temperature, water quantity, water start-stop, balance inquiry and recharging and other operations through the mobile phone APP.

[0047] As shown, Figure 4 The electronic communication meter box 20 is also provided with the mechanical dial 26, which can provide accurate water meter readings. When the readings of the digital display screen 22 cannot be accurately obtained, the mechanical dial 26 can be used as a backup system to ensure the accuracy of the data. For example, in the case of limited communication facilities, ordinary Internet of Things water meters cannot realize data monitoring, while the mechanical dial 26 can provide accurate data. The mechanical dial 26 can also improve the security of the Internet of Things water meter and prevent data loss. If the Internet of Things water meter fails, the mechanical dial 26 can make backup records to prevent data loss and improve the stability of the Internet of Things water meter.

[0048] The mechanical dial 26 is rotatably installed with a protective cover 21 made of transparent acrylic material, which can protect the mechanical dial 26 without affecting reading, and ensure the normal use of the mechanical dial 26. The protective cover 21 can also be flipped open to facilitate the maintenance and repair of the mechanical dial 26.

[0049] As shown, Figure 1 and Figure 2 The meter body 10 is fixedly installed with an inlet pipe 30 and an outlet pipe 60 on both sides, respectively. The inlet pipe 30 is connected to the heating inner container of the water heater, so that the boiling water in the heating inner container can enter the inside of the meter body 10, and the water completed by metering in the inside of the meter body 10 can be guided out through the outlet pipe 60.

[0050] A temperature regulating ball 40 is fixedly installed on the water inlet pipe 30. The boiling water will pass through the temperature regulating ball 40 before entering the meter body 10. A cold water pipe 50 is fixedly installed on the temperature regulating ball 40. The cold water pipe 50 is connected to the tap water pipeline. Normal temperature tap water can enter the temperature regulating ball 40 through the cold water pipe 50 and mix with the boiling water passing through to achieve the purpose of regulating the water temperature.

[0051] A first water valve 51 is fixedly installed on the cold water pipe 50. The first water valve 51 is used to control the supply speed of tap water. By controlling the supply speed of tap water, the regulated temperature of water can be controlled.

[0052] As shown in the figure, an inner sphere 41 is fixedly installed inside the temperature regulating ball 40. The inner sphere 41 is arranged concentrically with the temperature regulating ball 40. After the boiling water enters the temperature regulating ball 40, the inner sphere 41 will block the turbulence and disperse the boiling water into the gap between the temperature regulating ball 40 and the inner sphere 41.

[0053] A first connecting pipe 411 is fixedly mounted on the inner sphere 41. The cold water pipe 50 communicates with the interior of the inner sphere 41 through the first connecting pipe 411. The inner sphere 41 is provided with a plurality of through-holes 413. Tap water can enter the inner sphere 41 through the first connecting pipe 411 and then be evenly released into the gap between the thermostat ball 40 and the inner sphere 41 through the through-holes 413. This allows tap water to mix evenly with the boiling water passing through it, quickly and evenly adjusting the temperature and ensuring a stable outlet water temperature.

[0054] like Figure 5 and Figure 6 As shown, a data acquisition module is installed inside the meter body 10. The data acquisition module includes a metering component and a temperature measurement component. The metering component includes an impeller 11 and a metering sensor. Impeller 11 is rotatably connected to the inside of the meter body 10. As water passes through the meter body 10, it drives the impeller 11 to rotate. The metering sensor can be a reed switch sensor, a Hall effect sensor, or a photoelectric sensor, and works in conjunction with the impeller 11 to achieve water metering.

[0055] The temperature measurement component includes a temperature sensor 12, which is fixedly installed inside the meter body 10 and can monitor the temperature of the water in real time.

[0056] The electronic communication meter box 20 is internally integrated with a data processing module for analyzing and processing the water volume and temperature data collected by the metering component and the temperature measurement component. The data processing module includes a charging calculation module, which calculates the fee based on the water volume and water temperature. The charging calculation module calculates the fee based on the water volume and water temperature using the following formula:

[0057] F=C / 100*Q*R

[0058] Among them, F is the receivable fee, C is the water temperature, Q is the water volume, and R is the unit price of water.

[0059] Specifically, the student sets the water temperature and the water quantity by swiping the card or scanning the code, and starts the water outlet. During the water outlet process, the boiling water in the heating inner container of the water heater passes through the inside of the temperature regulating ball 40. At this time, the opening and closing size of the first water valve 51 is controlled according to the set water temperature, so that tap water is injected into the inside of the inner ball 41 through the cold water pipe 50 at a specific speed. The tap water is uniformly released into the boiling water through a plurality of through holes 413, so as to realize the sufficient mixing of the tap water and the boiling water, thereby quickly forming the water of the required temperature. After the mixed water passes through the inside of the surface body 10, the water is metered by driving the impeller 11 to rotate and cooperating with the metering sensor, and the temperature of the water is detected by the temperature sensor 12. According to the water temperature and the water quantity, reasonable charging can be realized by using the formula F=C / 100*Q*R.

[0060] The reasonable place of charging according to the water temperature and the water quantity is that the charging can be realized according to the energy consumption of the water heater. When the student needs water of a specific temperature and a specific quantity, the water can be directly taken by the water heater, and the charging can be matched according to the water temperature and the water quantity of the taken water, so that the charging difference caused by the temperature difference is avoided. That is to say, the charging standard has good rationality because of the temperature variable, so that the water use is fair, and the popularization and application of the intelligent water heater with adjustable temperature are promoted.

[0061] Compared with manually mixing tap water after directly taking out boiling water, the student can accurately take the water of the required temperature by the electronic Internet of Things water meter, and the possibility of scalding accidents is greatly reduced, which is beneficial to the safe use of the water heater.

[0062] As shown in Figure 2 and Figure 3 , the surface body 10 is connected with a water collecting and cooling assembly. The water collecting and cooling assembly includes a first water collecting cylinder 70 and a second water collecting cylinder 80, the first water collecting cylinder 70 and the second water collecting cylinder 80 are fixed, and the first water collecting cylinder 70 and the second water collecting cylinder 80 are both used for collecting the residual water inside the surface body 10.

[0063] The first water collecting cylinder 70 is connected with the surface body 10 through a first water guide pipe 71, the first water guide pipe 71 is fixedly installed with a first electromagnetic valve 711, and the first electromagnetic valve 711 is used for controlling the opening and closing of the first water guide pipe 71; the second water collecting cylinder 80 is connected with the surface body 10 through a second water guide pipe 81, the second water guide pipe 81 is fixedly installed with a second electromagnetic valve 811, and the second electromagnetic valve 811 is used for controlling the opening and closing of the second electromagnetic valve 811.

[0064] Specifically, since part of water will remain in the meter body 10 after each water taking, the meter body 10 is in a long-term water-filled state, which not only damages the internal components and affects the service life of the electronic Internet of Things water meter, but also forms dirt such as scale, which pollutes the interior of the meter body 10 and endangers the health of students. Therefore, by setting the first water collecting cylinder 70 and the second water collecting cylinder 80, the water remaining in the meter body 10 after each water taking can be collected in the first water collecting cylinder 70 or the second water collecting cylinder 80 through the opening of the first electromagnetic valve 711 or the second electromagnetic valve 811, so as to prevent the internal components of the meter body 10 from being damaged by long-term immersion in water or the water remaining in the meter body 10 from forming pollution for a long time, which is conducive to the long-term stable and safe use of the electronic Internet of Things water meter.

[0065] If the water remaining in the meter body 10 is water formed by combining boiling water and tap water, it cannot be directly drunk after cooling; if the water remaining in the meter body 10 is boiling water, it can be directly drunk after cooling. For the water that cannot be directly drunk, it is collected in the first water collecting cylinder 70; for the water that can be directly drunk, it is collected in the second water collecting cylinder 80, so as to realize the classified collection of the water remaining in the meter body 10.

[0066] Preferably, the first water collecting cylinder 70 and the second water collecting cylinder 80 are made of heat-conducting metal materials, which have good heat dissipation effect. The collected water can be quickly cooled to become normal temperature water like tap water.

[0067] A three-way pipe 90 is fixedly installed between the first water collecting cylinder 70 and the second water collecting cylinder 80, two ends of the three-way pipe 90 are respectively connected with the interiors of the first water collecting cylinder 70 and the second water collecting cylinder 80, and an electric three-way valve 91 is fixedly installed on the three-way pipe 90, which is used to control the opening and closing of the three-way pipe 90 and the interiors of the first water collecting cylinder 70 and the second water collecting cylinder 80.

[0068] One end of the electric three-way valve 91 is connected with a backwater assembly, which includes a backwater pipe 92, one end of the backwater pipe 92 is fixed with one end of the electric three-way valve 91, and the other end of the backwater pipe 92 is fixed on the temperature regulating ball 40. A water pump 93 and a second water valve 94 are fixedly installed on the backwater pipe 92, and the second water valve 94 is used to control the opening and closing of the backwater pipe 92. The water pump 93 can pump the water collected in the first water collecting cylinder 70 or the second water collecting cylinder 80 into the temperature regulating ball 40, so that the water collected in the first water collecting cylinder 70 and the second water collecting cylinder 80 can be used as normal temperature water like tap water to adjust the water temperature, realizing the recycling of the collected water.

[0069] A second connecting pipe 412 is fixedly mounted on the inner sphere 41, and the return pipe 92 communicates with the interior of the inner sphere 41 through the second connecting pipe 412. In other words, the water collected in the first and second water collection barrels 70 and 80 is first injected into the inner sphere 41, similar to tap water, and then released into the boiling water through the plurality of through holes 413, ensuring efficient water temperature regulation.

[0070] Specifically, if the water drawn the previous time was boiling water, then the remaining water inside the meter body 10 is also boiling water. After the water is drawn, the second solenoid valve 811 can be opened to allow the boiling water remaining inside the meter body 10 to be introduced into the second water collection barrel 80 through the second water conduit 81. After the second water collection barrel 80 cools naturally, it becomes boiled water that can be directly drunk. After being mixed with boiling water again, the water of a specific temperature formed can still be directly drunk. Therefore, when students want to obtain water of a suitable temperature that can be directly drunk, they can use the water pump 93 to extract boiled water from the second water collection barrel 80 and inject it into the temperature control ball 40 during the water drawing process to adjust the water temperature, thereby obtaining water of a suitable temperature that can be directly drunk.

[0071] If the water previously drawn was a mixture of boiling water and tap water, the remaining water inside the meter body 10 is still a mixture of boiling water and tap water. After the water is drawn, the first solenoid valve 711 can be opened to allow the remaining water inside the meter body 10 to be directed into the first water collection barrel 70 through the first water conduit 71. After it cools naturally, it cannot be directly drunk. After being mixed with boiling water again, it still cannot be directly drunk and can only be used as normal temperature tap water for adjusting the water temperature. Therefore, when students want to obtain water of a specific non-drinkable temperature, they can first use the water pump 93 to adjust the water temperature in the first water collection barrel 70 during the water drawing process. After the water in the first water collection barrel 70 is used up, the water temperature can be adjusted again with tap water, thereby obtaining non-drinkable water of a suitable temperature.

[0072] In addition, since the best drinking period of boiled water is two days, if the boiled water collected in the second water collection barrel 80 is not reused after two days, it will be directly used as room temperature tap water, just like the water collected in the first water collection barrel 70, to ensure the safety of students' drinking water.

[0073] In summary, by reusing the water collected in the first and second water collection cylinders 70 and 80, students can extract a variety of water types to meet their various needs while saving water resources. This electronic IoT water meter can be well integrated with a water heater, enriching the functionality of the water heater.

[0074] When the student only takes boiling water, the temperature and quantity of water are set by the electronic internet of things water meter, and the water is taken without adjusting the temperature.

[0075] Compared with the prior art, the electronic internet of things water meter can adjust the water temperature through the temperature regulating ball 40, so as to meet different water demands, and can reasonably charge according to the water temperature and quantity, so as to realize fair water use, eliminate the obstacles to the popularization of intelligent water heaters in specific occasions, and facilitate the popularization and use of the intelligent water heaters.

[0076] The first water collecting cylinder 70 and the second water collecting cylinder 80 can collect the residual water in the meter body 10, so that the residual water in the meter body 10 can be discharged in time, the residual water is prevented from polluting and damaging the inside of the meter body 10, the water safety is ensured, and the service life of the meter body 10 is effectively prolonged.

[0077] The collected water can be reused through the backflow assembly, so as to better meet different water demands and save water.

[0078] It is obvious for those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, and the present application can be implemented in other specific forms without departing from the spirit or essential characteristics of the present application.

Any reference signs in the claims should not be regarded as limiting the claims.
