DETAILED DESCRIPTION

[0044] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0045] like Figure 1-Figure 7As shown, an electronic Internet of Things water meter in one embodiment of the present invention is described by taking the water heater used in the hot water room of a university dormitory as an example, including 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 parameters such as temperature, water volume, water fee, and balance, so as to intuitively obtain the data of each parameter. The operation button 23 includes but is not limited to a water temperature adjustment button, a water volume adjustment button, and a start-stop button, and students can control the water outlet temperature, water volume, and water outlet start-stop, etc. through the operation button 23.

[0046] The card slot 24 can recognize IC cards, and students can insert the cards to get water, which is convenient for transactions. Students can also scan the code scanning area 25 through the mobile phone APP to log in to the system, so as to control the water temperature, water volume, water start and stop, balance inquiry, recharge and other operations through the mobile phone APP.

[0047] like Figure 4 As shown, the electronic communication meter box 20 is also provided with a 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, when communication facilities are limited, ordinary IoT water meters cannot achieve data monitoring, while the mechanical dial 26 can provide accurate data. The mechanical dial 26 can also improve the security of the IoT water meter and prevent data loss. If the IoT water meter fails, the mechanical dial 26 can perform backup records to prevent data loss and improve the stability of the IoT water meter.

[0048] A protective cover 21 is rotatably mounted on the mechanical dial 26. The protective cover 21 is made of transparent acrylic material, which can protect the mechanical dial 26 without affecting reading, ensuring the normal use of the mechanical dial 26. The protective cover 21 can also be flipped open to facilitate the inspection and maintenance of the mechanical dial 26.

[0049] like Figure 1 and Figure 2 As shown, a water inlet pipe 30 and a water outlet pipe 60 are fixedly installed on both sides of the meter body 10. The water inlet pipe 30 is connected to the heating tank of the water heater, so that the boiling water in the heating tank can enter the interior of the meter body 10, and the water measured inside the meter body 10 can be discharged through the water 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 function 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, and the cold water pipe 50 is connected to the inner part 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 temperature regulating ball 40 and the inner sphere 41 through the plurality of through holes 413, and evenly and fully mixed with the boiling water passing through, so as to quickly and evenly adjust the temperature and ensure the stability of the outlet water temperature.

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

[0055] The temperature measuring 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, which is used to analyze and process the water volume and water temperature data collected by the metering component and the temperature measuring component. The data processing module includes a charging calculation module, which calculates the charge based on the water volume and water temperature. The charging calculation module calculates the charge based on the water volume and water temperature. The formula is:

[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, students swipe cards or scan codes to set the water intake temperature and water intake volume, and start water discharge. During the water discharge process, the boiling water in the heating tank of the water heater passes through 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 inner sphere 41 at a specific speed through the cold water pipe 50. The tap water is evenly released into the boiling water through a number of through holes 413, so that the tap water and the boiling water are fully mixed, so as to quickly form water of the required temperature. When the mixed water passes through the inside of the meter body 10, the water is metered by driving the impeller 11 to rotate and cooperate with the metering sensor. At the same time, the temperature sensor 12 detects the temperature of the water. The formula F=C / 100*Q*R can be used to reasonably charge according to the water temperature and the water volume.

[0060] The rationale of using water temperature combined with water volume for billing is that it can be billed according to the energy consumption of the water heater. When students need water of a specific temperature and volume, they can get it directly through the water heater, and the billing can be matched according to the water temperature and water volume, without causing billing differences due to temperature differences. In other words, the inclusion of temperature as a variable in the billing standard makes it reasonable, can achieve water fairness, and promote the popularization and application of intelligent water heaters with adjustable temperature.

[0061] Compared with directly taking out boiling water and manually adding tap water, the electronic IoT water meter enables students to accurately obtain water of the required temperature, greatly reduces the possibility of scalding accidents, and is conducive to the safe use of the water heater.

[0062] like Figure 2 and Figure 3 As shown, a water collecting and cooling assembly is connected to the meter body 10. The water collecting and cooling assembly includes a first water collecting cylinder 70 and a second water collecting cylinder 80, which are fixed to each other and are used to collect residual water inside the meter body 10.

[0063] A first water pipe 71 is connected between the first water collecting cylinder 70 and the meter body 10, and a first solenoid valve 711 is fixedly installed on the first water pipe 71, and the first solenoid valve 711 is used to control the opening and closing of the first water pipe 71; a second water pipe 81 is connected between the second water collecting cylinder 80 and the meter body 10, and a second solenoid valve 811 is fixedly installed on the second water pipe 81, and the second solenoid valve 811 is used to control the opening and closing of the second solenoid valve 811.

[0064] Specifically, after each water intake, some water will remain inside the meter body 10, causing the meter body 10 to be filled with water for a long time, which will not only damage the internal components and affect the service life of the electronic IoT water meter, but also form scale and other dirt if this part of water exists inside the meter body 10 for a long time, causing the inside of the meter body 10 to be polluted and endangering the health of students. Therefore, by setting the first water collecting cylinder 70 and the second water collecting cylinder 80, after each water intake, by opening the first solenoid valve 711 or the second solenoid valve 811, the water remaining inside the meter body 10 can be discharged into the first water collecting cylinder 70 or the second water collecting cylinder 80 in time through the first water conduit 71 or the second water conduit 81 and collected, so as to prevent the internal components of the meter body 10 from being damaged by being immersed in water for a long time or water from remaining inside the meter body 10 for a long time to form pollution, which is conducive to the long-term stable and safe use of the electronic IoT water meter.

[0065] If the water remaining in the meter body 10 is a combination of boiling water and tap water, it cannot be drunk directly after cooling; if the water remaining in the meter body 10 is boiling water, it can be drunk directly after cooling. The water that cannot be drunk directly is collected in the first water collection cylinder 70; the water that can be drunk directly is collected in the second water collection cylinder 80, so that the residual water in the meter body 10 can be collected in a classified manner.

[0066] Preferably, the first water collecting cylinder 70 and the second water collecting cylinder 80 are both made of heat-conducting metal material, which has a good heat dissipation effect, so that the collected water can be quickly cooled to become water of normal temperature 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. The two ends of the three-way pipe 90 are respectively connected to the interior of the first water collecting cylinder 70 and the second water collecting cylinder 80. An electric three-way valve 91 is fixedly installed on the three-way pipe 90. The electric three-way valve 91 is used to control the connection and disconnection of the three-way pipe 90 and the interior 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 to a water return assembly, which includes a water return pipe 92, one end of which is fixed to one end of the electric three-way valve 91, and the other end of the water return pipe 92 is fixed to the temperature control ball 40. A water pump 93 and a second water valve 94 are fixedly installed on the water return pipe 92, and the second water valve 94 is used to control the on and off of the water return pipe 92. The water collected in the first water collection cylinder 70 or the second water collection cylinder 80 can be pumped out by the water pump 93 and sent to the temperature control ball 40, so that the water collected in the first water collection cylinder 70 and the second water collection cylinder 80 can be used as normal temperature water similar to tap water, which is used to adjust the water temperature and realize the recycling of the collected water.

[0069] The inner sphere 41 is fixedly mounted with a second connecting pipe 412, and the return pipe 92 is connected to the inner sphere 41 through the second connecting pipe 412. That is, the water collected in the first water collecting cylinder 70 and the second water collecting cylinder 80 is first injected into the inner sphere 41 like tap water, and then released into the boiling water through the plurality of through holes 413, ensuring efficient water temperature regulation.

[0070] Specifically, when the water drawn last time is boiling water, the water remaining 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 tube 80 through the second water conduit 81. After the second water collection tube 80 is naturally cooled, it becomes boiled water that can be drunk directly. After mixing with boiling water again, the water of a specific temperature formed can still be drunk directly. Therefore, when students want to get water with a suitable temperature that can be drunk directly, they can use the water pump 93 to extract the boiled water inside the second water collection tube 80 and inject it into the temperature regulating ball 40 during the water drawing process to adjust the water temperature, so that they can get water with a suitable temperature that can be drunk directly.

[0071] When the water drawn last time is water mixed with boiling water and tap water, the water remaining inside the meter body 10 is still water mixed with boiling water and tap water. After the water is drawn, the first solenoid valve 711 can be opened to allow the water remaining inside the meter body 10 to be introduced into the first water collection barrel 70 through the first water conduit 71. After natural cooling, it cannot be drunk directly. After being mixed with boiling water again, it still cannot be drunk directly and can only be used as normal temperature tap water to adjust the water temperature. Therefore, when students want to obtain non-drinking water of a specific temperature when drawing water, they can first use the water pump 93 to adjust the water temperature when drawing water. After the water inside the first water collection barrel 70 is used up, the water temperature can be adjusted by tap water, so that non-drinking water with a suitable temperature can be obtained.

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

[0073] In summary, by reusing the water collected in the first water collecting cylinder 70 and the second water collecting cylinder 80, students can take out various types of water to meet their various needs while saving water resources. The electronic Internet of Things water meter can be well combined with the water heater to enrich the function of the water heater.

[0074] When in use, when students only take boiling water, they can directly set the water temperature and water volume through the electronic Internet of Things water meter to take water without adjusting the temperature. When students need to take non-drinking water of a specific temperature, they can set the water temperature and water volume through the electronic Internet of Things water meter, and the boiling water and tap water enter the temperature regulating ball 40 at the same time, fully mix inside the temperature regulating ball 40, and take out after adjusting the temperature. When students need to take drinkable water of a specific temperature, they can set the water temperature and water volume through the electronic Internet of Things water meter, so that the water pump 93 draws the boiled water inside the second water collection cylinder 80 and the boiling water into the temperature regulating ball 40 together, and takes out after adjusting the temperature. During the water-taking process, according to the formula F=C / 100*Q*R, the temperature variable is added for billing, so as to achieve reasonable and fair billing for water taking.

[0075] Compared with the prior art, the electronic IoT water meter of the present invention can adjust the water temperature through the temperature regulating ball 40 to meet different water needs, and can reasonably charge according to the water temperature and water volume, thereby achieving water fairness, eliminating the obstacles to the popularization of intelligent water heaters in specific occasions, and facilitating their popularization and use;

[0076] The first water collecting cylinder 70 and the second water collecting cylinder 80 can collect the residual water inside the meter body 10, so that the residual water inside the meter body 10 can be discharged in time, preventing the residual water from polluting and damaging the inside of the meter body 10, ensuring water safety, and effectively extending the service life of the meter body 10;

[0077] The collected water can be reused through the reflux component to better meet different water needs and save water.

[0078] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
