Description

Technical Field

[0001] This disclosure relates to the field of electrical control technology, and in particular to a method for controlling carbonic acid concentration, a carbonic acid solution generating device, and related equipment. Background Technology

[0002] Carbonated water is a dissolved liquid formed by mixing carbon dioxide gas with water. Because the carbon dioxide gas in carbonated water, after entering the body through the skin, can dilate and soften blood vessels, promote metabolism, and improve skin blood circulation, an increasing number of carbonated water bath products (such as carbonated spring showers) have appeared on the market. Carbonated water bath products include a water supply section, a gas supply section, and a mixing section. The water supply section provides water, the gas supply section provides carbon dioxide gas, and the mixing section is connected to both the water supply section and the gas supply section to mix the water and carbon dioxide gas to form a carbonated spring.

[0003] Currently, the carbonated water bath products provided in related technologies mainly increase the concentration of carbon dioxide gas in carbonated springs through the following two methods:

[0004] The first method involves designing the structure of relevant parts of the product (e.g., the shower head of a carbonated spring shower) to increase the contact area between carbon dioxide gas and water, thereby increasing the solubility of carbon dioxide gas in water. However, because carbon dioxide gas is easily volatilized in water, this method may result in the concentration of carbon dioxide in the mixed carbonated spring water not reaching the ideal concentration.

[0005] The second method involves manually controlling the output of carbon dioxide gas from the supply unit (e.g., a carbon dioxide cylinder) to increase the solubility of carbon dioxide gas in water. However, this method cannot precisely control the output of carbon dioxide gas and is prone to waste.

[0006] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art.

[0045] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the examples set forth herein; rather, they are provided so that this disclosure will be more comprehensive and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0046] Furthermore, the accompanying drawings are merely illustrative of this disclosure and are not necessarily drawn to scale. The same reference numerals in the drawings denote the same or similar parts, and therefore repeated descriptions of them will be omitted. Some block diagrams shown in the drawings are functional entities and do not necessarily correspond to physically or logically independent entities. These functional entities may be implemented in software, in one or more hardware modules or integrated circuits, or in different network and / or processor devices and / or microcontroller devices.

[0047] The specific implementation methods of the embodiments of this disclosure will now be described in detail with reference to the accompanying drawings.

[0048] Figure 1 A schematic diagram of an exemplary application system architecture to which the carbonic acid concentration control method of the embodiments of this disclosure can be applied is shown. For example... Figure 1 As shown, the system architecture may include: a water supply section 101, a gas supply section 102, a mixing section 103, a temperature sensor 104, a gas pressure sensor 105, a carbon dioxide concentration sensor 106, and a controller 107.

[0049] The water supply section 101 is used to provide water flow;

[0050] Gas supply section 102 is used to supply carbon dioxide gas;

[0051] The mixing section 103 is connected to the water supply section 101 and the gas supply section 102, and is used to mix carbon dioxide gas and water flow to form a carbonic acid solution.

[0052] Temperature sensor 104 is installed in water supply section 101 and is used to collect the actual temperature value of water flow.

[0053] A pressure sensor 105 is installed in the gas supply section 102 and is used to collect the actual pressure value of carbon dioxide gas.

[0054] A carbon dioxide concentration sensor 106 is installed in the carbonic acid solution output from the mixing section 103 to collect the actual volume concentration value of carbon dioxide in the carbonic acid solution.

[0055] The controller 107 is connected to the pressure sensor 105, the temperature sensor 104 and the carbon dioxide concentration sensor 106 respectively, and is used to control the carbon dioxide supply of the gas supply section 101 according to the actual pressure value of carbon dioxide gas collected by the pressure sensor 105, the actual temperature value of water flow collected by the temperature sensor 104 and the actual carbon dioxide volume concentration value of carbonic acid solution collected by the carbon dioxide concentration sensor 106.

[0056] To mix carbon dioxide gas and water to form a carbonated solution, a typical carbonated solution generating device includes three parts: a water supply section 101, a gas supply section 102, and a mixing section 103. However, to achieve precise control of the carbon dioxide supply, the carbonate concentration control scheme provided in this embodiment requires a temperature sensor 104 to be installed in the water supply section 101 to collect the actual temperature value of the water supplied by the water supply section 101; a pressure sensor 105 to be installed in the gas supply section 102 to collect the actual pressure value of the carbon dioxide gas supplied by the gas supply section 102; and a carbon dioxide concentration sensor 106 to be installed in the carbonated solution output from the mixing section 103 to collect the actual carbon dioxide volume concentration value of the carbonated solution.

[0057] The controller 107 mentioned above can be a controller built into the carbonic acid solution generator, or a controller on a control device connected to the carbonic acid solution generator. That is, the method for controlling the carbon dioxide supply of the gas supply section based on the data collected by each sensor in this embodiment of the present disclosure can be executed by the carbonic acid solution generator or by other control devices.

[0058] In some embodiments, such as Figure 2 As shown, the application system provided in this embodiment may further include: a gas supply valve 108, disposed at the output end of the gas supply section 102, for adjusting the carbon dioxide supply volume of the gas supply section 102; in this embodiment, the controller 107 is also used to control the opening value of the gas supply valve. When the controller 107 obtains the actual gas pressure value of carbon dioxide gas collected by the pressure sensor 105, the actual temperature value of water collected by the temperature sensor 104, and the actual carbon dioxide volume concentration value of the carbonate solution collected by the carbon dioxide concentration sensor 106, it can adjust the opening value of the gas supply valve, thereby realizing the control of the carbon dioxide supply volume.

[0059] First, this disclosure provides a method for controlling carbonic acid concentration, which can be executed by any electronic device with computing power. In some embodiments, the carbonic acid concentration control method provided in this disclosure can be executed by the controller of the system architecture described above.

[0060] Figure 3 A flowchart of a method for controlling carbonic acid concentration according to an embodiment of this disclosure is shown, as follows: Figure 3 As shown, the carbonic acid concentration control method provided in this embodiment includes the following steps:

[0061] S302, collects the actual gas pressure of carbon dioxide gas, the actual temperature of water, and the actual volume concentration of carbon dioxide in the carbonate solution formed by mixing carbon dioxide gas and water.

[0062] S304 controls the carbon dioxide supply to the carbon dioxide generating device based on the actual gas pressure of carbon dioxide gas, the actual temperature of water, and the actual volume concentration of carbon dioxide in the carbonic acid solution.

[0063] The carbon dioxide concentration control method provided in the embodiments of this disclosure collects the actual gas pressure of carbon dioxide gas, the actual temperature of water, and the actual volume concentration of carbon dioxide in the carbonic acid solution formed by mixing carbon dioxide gas and water. Based on these parameters, the carbon dioxide supply to the carbonic acid solution generator is controlled. Since the solubility of carbon dioxide gas in water is affected by gas pressure and temperature, the solution provided in this disclosure comprehensively considers these factors to control the carbon dioxide supply to the carbonic acid solution generator, enabling more precise control of the carbon dioxide concentration in the solution. By automatically matching the carbon dioxide supply, a constant carbon dioxide concentration can be maintained in the solution, thereby saving carbon dioxide consumption.

[0064] In some embodiments, S304 can be implemented through the following steps: collecting the actual pressure value of carbon dioxide gas, the actual temperature value of water, and the actual volume concentration value of carbon dioxide in the carbonated solution formed by mixing carbon dioxide gas and water; calculating the theoretical mass concentration value of carbon dioxide gas at the actual pressure value and actual temperature value based on the actual pressure value of carbon dioxide gas, the actual temperature value of water, and the actual volume concentration value of carbon dioxide in the carbonated solution; querying the standard mass concentration value of carbon dioxide gas at the actual temperature value based on the water solubility table of carbon dioxide gas at the standard pressure value; and adjusting the opening value of the carbon dioxide gas supply valve according to the actual pressure value, the theoretical mass concentration value, the standard pressure value, and the standard mass concentration value to control the carbon dioxide supply of the carbonated solution generator.

[0065] In some embodiments, the carbonic acid concentration control method provided in this disclosure may further include the following steps: obtaining the theoretical carbon dioxide volume concentration value of a preset configured carbonic acid solution; and determining the initial opening value of the carbon dioxide gas supply valve based on the theoretical carbon dioxide volume concentration value of the carbonic acid solution.

[0066] In some embodiments, the theoretical mass concentration of carbon dioxide gas at actual pressure and actual temperature can be calculated using the following formula:

Indicates the standard temperature value; Indicates the actual temperature value; This indicates the actual air pressure value; This represents the standard atmospheric pressure value. 1 PPM = 1 cm 3 / m 3 =10 -6 .

[0069] Optionally, The value is 22.4, which refers to the molar volume constant of a gas under standard conditions. Under standard conditions, the volume occupied by 1 mole (mol) of any ideal gas is approximately 22.4 liters (L), with the unit being L / mol.

[0070] In some embodiments, the standard pressure and standard temperature values ​​in this disclosure can be the pressure and temperature values ​​of carbon dioxide gas under standard conditions. The value can be 273K, which is the Kelvin temperature, equivalent to 0 degrees Celsius. Kelvin temperature is used in the calculation. The value can be 101.3 kPa.

[0071] Furthermore, in some embodiments, the opening value of the carbon dioxide gas supply valve can be adjusted based on the actual gas pressure value, theoretical mass concentration value, standard gas pressure value, and standard mass concentration value to control the carbon dioxide supply of the carbon dioxide solution generator: Calculate the gas pressure ratio based on the actual gas pressure value and the standard gas pressure value; calculate the mass concentration ratio based on the theoretical mass concentration value and the standard mass concentration value; determine whether the difference between the gas pressure ratio and the mass concentration ratio is within a preset error range (ideally, the gas pressure ratio and the mass concentration ratio are equal); if the difference between the gas pressure ratio and the mass concentration ratio does not exceed the preset error range, maintain the opening value of the carbon dioxide gas supply valve unchanged; if the difference between the gas pressure ratio and the mass concentration ratio exceeds the preset error range, adjust the opening value of the carbon dioxide gas supply valve.

[0072] Furthermore, in some embodiments, adjusting the opening value of the carbon dioxide gas supply valve can be achieved through the following steps: determining whether the pressure ratio is greater than the mass concentration ratio; if the pressure ratio is greater than the mass concentration ratio (indicating a low carbon dioxide concentration), increasing the opening value of the carbon dioxide gas supply valve, and determining the percentage increase based on the actual pressure value, theoretical mass concentration value, standard pressure value, and standard mass concentration value; if the pressure ratio is less than the mass concentration ratio (indicating a high carbon dioxide concentration), decreasing the opening value of the carbon dioxide gas supply valve, and determining the percentage decrease based on the theoretical mass concentration value, standard mass concentration value, actual pressure value, and standard pressure value of the carbon dioxide gas at the actual pressure and actual temperature values.

[0073] In some embodiments, the opening value of the carbon dioxide gas supply valve can be determined by the following formula:

[0074] (2)

[0075] (3)

[0076] in, This indicates the percentage increase in the opening degree of the carbon dioxide gas supply valve; This indicates the percentage reduction in the opening degree of the carbon dioxide gas supply valve. This represents the theoretical mass concentration of carbon dioxide gas at actual temperature and pressure values, and the unit can be mg / m³. 3 ; This represents the standard mass concentration of carbon dioxide gas at actual temperature and standard atmospheric pressure, and the unit can be mg / m³. 3 ; This represents the actual air pressure value, and the unit can be kPa. The value represents the standard atmospheric pressure, which can be 101.3 kPa. The water solubility of carbon dioxide (CO2) gas at 101.3 kPa is shown in Table 1.

[0077] Table 1

[0078]

[0079] Based on the same inventive concept, this disclosure also provides a carbonic acid solution generating apparatus, which may include... Figure 1 The components shown are a water supply section 101, a gas supply section 102, a mixing section 103, a temperature sensor 104, a pressure sensor 105, a carbon dioxide concentration sensor 106, and a controller 107.

[0080] In some embodiments, the carbonic acid solution generating apparatus provided in this disclosure may further include a gas supply valve 108, which is disposed at the output end of the gas supply section 102 and is used to adjust the carbon dioxide supply volume of the gas supply section 101; the opening value of the gas supply valve is controlled by the controller 107 to control the carbon dioxide supply volume.

[0081] The carbonic acid solution generating device provided in this embodiment can be, but is not limited to, a device for a carbonic acid bath. In some embodiments, if the carbonic acid solution generating device provided in this embodiment is a device for a carbonic acid bath, then the device for a carbonic acid bath provided in this embodiment can be a carbonic acid spring shower. The carbonic acid spring shower can collect the actual temperature value of the water through an NTC (Negative Temperature Coefficient) thermistor; collect the actual gas pressure value of carbon dioxide gas through a gas pressure gauge; in this embodiment, a carbon dioxide sensor is also required at the water outlet of the carbonation device to collect the actual carbon dioxide volume concentration value of the carbonic acid solution.

[0082] The following example uses a carbonated spring shower, combined with... Figure 4 , Figure 5 and Figure 6 The method for controlling carbonic acid concentration provided in the embodiments of this disclosure will be described in detail. Figure 4 This is a three-dimensional structural diagram of a carbonated spring shower. Figure 5 A top view of the internal structure of a carbonated spring shower after the outer casing has been removed. Figure 6 This is a schematic diagram of the water and gas circuits of a carbonated spring shower.

[0083] Figure 4 The temperature control valve 104 shown can control the ratio of hot water to cold water to control the water temperature supplied by the water supply section 101, and can replace the temperature sensor used to collect the water temperature in the embodiments of this disclosure. Figure 4 The push-button switch valve 109 shown is used to open or close the water flow at the outlet 110.

[0084] like Figure 5 and Figure 6 As shown, in the water supply section 101: hot water and cold water (municipal water supply) enter the carbonization device 103 (i.e., the mixing section mentioned above) through the temperature regulating valve 115 and the water pressure reducing valve 112; the water supply section 101 can display the inlet flow rate and inlet temperature value on the digital tube 113 (the inlet temperature can be used as the temperature of the water supplied by the water supply section 101). The generator 111 is used to supply power to the digital tube display 113.

[0085] In the gas supply section 102, a gas cylinder provides the gas source, and the output carbon dioxide gas enters the carbonization device 103 (i.e., the mixing section) via a gas pressure reducing valve 116, a proportional valve 108 (i.e., the aforementioned gas supply valve), and a gas pressure gauge 105 (i.e., the aforementioned gas pressure sensor). The gas pressure gauge 105 can collect the gas pressure value (i.e., the actual gas pressure value) of the carbon dioxide gas supplied by the gas supply section 102. The touch switch 114 can be used to switch the carbon dioxide gas supplied by the gas supply section 102.

[0086] In this embodiment, a carbon dioxide concentration sensor 106, located before the water outlet 110 of the carbonated spring shower, detects the actual carbon dioxide volume concentration of the carbonated solution (i.e., the carbonated spring output by the carbonation device 103). After obtaining the temperature of the water supplied by the water supply section 101, the actual gas pressure of the carbon dioxide gas supplied by the gas supply section 102, and the actual carbon dioxide volume concentration of the carbonated spring output by the carbonation device 103, the opening ratio of the proportional valve 108 (gas supply valve) can be determined by the carbon dioxide concentration control method provided in this embodiment, thereby controlling the carbon dioxide supply to ensure a constant carbon dioxide concentration in the carbonated spring and saving carbon dioxide gas consumption.

[0087] Figure 7 This diagram illustrates a specific implementation flowchart of a carbonic acid concentration control method according to an embodiment of the present disclosure, as follows: Figure 7 As shown, the specific steps include the following:

[0088] S702, System Initialization.

[0092] S710 collects the actual volume concentration of carbon dioxide in a carbonated solution formed by mixing carbon dioxide gas and water.

[0093] S712 displays the actual volume concentration of carbon dioxide in the carbonated solution.

[0094] S714, Calculate the theoretical mass concentration of carbon dioxide gas at the actual pressure and temperature values ​​based on the actual gas pressure of carbon dioxide gas, the actual temperature of water, and the actual volume concentration of carbon dioxide in the carbonate solution.

[0095] S716, based on the water solubility table of carbon dioxide gas at standard atmospheric pressure, query the standard mass concentration value of carbon dioxide gas at the actual temperature.

[0096] S718 determines whether the difference between the pressure ratio and the mass concentration ratio is within a preset error range; if yes, proceed to S720; otherwise, proceed to S706, S708, and S710. Ideally, the pressure ratio and the mass concentration ratio are equal, but in practical applications, a preset error range can be configured to make the pressure ratio and the mass concentration ratio very close.

[0097] S720, determine whether the pressure ratio is greater than the mass concentration ratio; if the pressure ratio is greater than the mass concentration ratio (indicating that the carbon dioxide concentration is low), then execute S722; if the pressure ratio is less than the mass concentration ratio (indicating that the carbon dioxide concentration is high), then execute S724.

[0098] S722, increase the opening value of the carbon dioxide gas supply valve, and determine the increase ratio based on the actual gas pressure value, theoretical mass concentration value, standard gas pressure value, and standard mass concentration value.

[0099] S724, reduce the opening degree of the carbon dioxide gas supply valve, and determine the reduction ratio based on the theoretical mass concentration value, standard mass concentration value, actual gas pressure value, and standard gas pressure value of carbon dioxide gas at actual gas pressure and actual temperature values.

[0103] It should be noted that the data acquisition module 801 and the gas supply control module 802 mentioned above correspond to S302 to S304 in the method embodiment. The examples and application scenarios implemented by the above modules and corresponding steps are the same, but are not limited to the content disclosed in the above method embodiment.
