Description

Technical Field

[0001] The present invention relates to the technical field of beverage preparation, in particular to the technology of preparing sparkling water. Background Art

[0002] Sparkling water, also known as soda water, is a beverage rich in carbon dioxide (CO2). It gets its name from the fine bubbles that form when dissolved CO2 is released. With its refreshing taste and unique flavor, sparkling water has become popular in the health beverage market in recent years.

[0003] The taste of sparkling water is primarily determined by the fineness of its bubbles (particle size), concentration (number of bubbles per unit volume), and CO2 content. Sparkling water with a high concentration and finer bubbles has a smoother taste, while sparkling water with a lower concentration and coarser bubbles is more refreshing. Basic sparkling water typically consists solely of water and CO2. Some products add minerals like sodium and magnesium to enhance the flavor, while others incorporate flavored drinks like fruits and spices. It can be used for everyday thirst quenching, as a side dish, or in cocktails (such as mojitos) or as a fruit-based specialty drink.

[0004] Currently, some water purifiers are equipped with a sparkling water preparation function, allowing them to directly produce sparkling water for drinking. The principle of sparkling water production is to inject carbon dioxide into a liquid, causing it to dissolve. However, existing sparkling water modules have problems with low carbon dioxide dissolution efficiency, insufficient solubility saturation, and inflexible adjustment of the sparkling water concentration. As a result, the quality of the produced sparkling water needs to be improved. Summary of the Invention

[0005] The purpose of the present invention is to provide a bubble water preparation device, a control method and a water purifier to solve the problems of low carbon dioxide dissolution efficiency, insufficient dissolution saturation, and inflexible bubble water concentration adjustment in the prior art bubble water preparation.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0012] The control unit is electrically connected to the liquid valve, the gas valve and the detection unit respectively, and can independently adjust the opening of the liquid valve and the gas valve according to the target concentration parameter.

[0013] Furthermore, the tube body is provided with radially arranged air introduction holes, and according to the injection direction of the liquid, the air introduction holes are arranged behind the narrow hole portion; there are multiple air introduction holes, and the multiple air introduction holes are arranged at intervals along the circumference of the tube body; the block is provided with a blocking surface for blocking the jet formed by the liquid, the blocking surface is a plane, and the center of the blocking surface corresponds vertically to the jet formed by the liquid.

[0014] Furthermore, it further comprises a connecting rod and a bottom plate, wherein the first end of the connecting rod is fixedly connected to the output end of the tube body, and the second end is fixedly connected to the bottom plate, and the stopper is arranged on the bottom plate; the distance from the first end of the connecting rod to the axis of the tube body is smaller than the distance from the second end of the connecting rod to the axis of the tube body;

[0015] The liquid valve and the gas valve are both flow regulating electromagnetic valves.

[0016] Furthermore, the inner wall of the narrow hole portion is a conical structure, and a movable core shaft is provided in the tube body. The movable core shaft is a conical structure that matches the inner wall of the narrow hole portion. The movable core shaft is connected to a drive assembly located outside the tube body through a rotating rod.

[0019] A pressure sensor is provided near the narrow hole portion;

[0020] The liquid level sensor is arranged in the tank body.

[0021] The present invention also provides a control method using the bubble water preparation device, comprising the following steps:

[0022] (1) Receive the target bubble concentration parameter and taste parameter input by the user;

[0023] (2) Based on the target bubble concentration parameter and taste parameter, the control unit initializes the initial opening degrees of the liquid valve and gas valve, and the initial aperture of the narrow hole part;

[0024] (3) Start the liquid supply system and carbon dioxide supply system, so that the liquid forms a high-speed jet through the narrow hole part of the Venturi tube assembly, and carbon dioxide enters from the air intake hole to mix with the liquid. The high-speed liquid jet impacts the baffle and then atomizes to form tiny droplets and mixes with the carbon dioxide in the mixing chamber;

[0025] (4) The detection unit collects the actual liquid flow rate, actual carbon dioxide flow rate and actual bubble water concentration data in real time;

[0026] (5) The control unit dynamically adjusts the opening degrees of the liquid valve and gas valve according to the deviation value between the actual concentration of the bubble water and the target concentration, and selectively adjusts the aperture of the narrow hole part until the bubble water meeting the requirements of the target concentration and taste is prepared.

[0027] Further, the dynamic adjustment step includes:

[0028] When the deviation value ΔC = actual concentration - target concentration > 0.4 g / L, the control unit reduces the opening degree of the gas valve ΔV2 = k1×ΔC, and at the same time keeps the opening degree of the liquid valve unchanged;

[0029] When the deviation value -0.4 g / L ≤ ΔC ≤ 0.4 g / L, the control unit finely adjusts the opening degree of the liquid valve ΔV2 = k2×ΔC, where k2 < k1;

[0030] When the deviation value ΔC < -0.4 g / L, the control unit increases the opening degree of the gas valve ΔV2 = k3×|ΔC|, and at the same time reduces the opening degree of the liquid valve ΔV1 = k4×|ΔC|, where k3 and k4 are positive coefficients and k3 > k2;

[0031] The taste parameter includes the requirement for bubble fineness.

[0032] Further, it further includes:

[0033] Jet intensity control step:

[0034] Calculate the jet impact force F based on the actual liquid flow rate and the aperture of the narrow hole part;

[0035] When F < Fmin, the control unit increases the opening degree of the liquid valve to increase the liquid flow rate, or reduces the aperture of the narrow hole part until F is in the interval [Fmin, Fmax];

[0036] Where, F = ρ×Q² / (A×v), ρ is the liquid density, Q is the liquid flow rate, A is the cross-sectional area of ​​the narrow hole, v is the jet velocity, and Fmin and Fmax are determined according to the target concentration;

[0037] Temperature adaptive adjustment steps:

[0038] Real-time collection of liquid temperature T;

[0039] The CO2 supply parameters are compensated based on the preset temperature-solubility model. The compensation formula is: Qc_compensated = Qc_base × [1 + α×(T0 - T)], where Qc_compensated is the compensated CO2 flow rate, Qc_base is the base flow rate, α is the temperature coefficient, and T0 is the base temperature.

[0040] Intelligent learning optimization steps:

[0041] Record the target parameters, environmental parameters, adjustment process and final results during each preparation process;

[0042] Build a prediction model based on historical data to optimize initial parameter settings when preparing sparkling water with the same target parameters in the future;

[0043] When the cumulative number of preparations exceeds the preset threshold, the adjustment parameter database in the control unit is automatically updated to reduce the concentration deviation before the first adjustment by more than 40%;

[0044] Bubble fineness adjustment:

[0045] When high bubble fineness requirements are detected, the control unit reduces the aperture of the narrow hole to control the average droplet diameter within the range of 50-100μm;

[0046] When low bubble fineness requirements are detected, the control unit increases the aperture of the narrow hole portion so that the average droplet diameter is controlled within the range of 200-300μm.

[0047] The present invention also provides a water purifier using the bubble water preparation device.

[0048] The present invention also provides a water purifier applying the control method.

[0049] The advantages of the present invention are:

[0050] High dissolution efficiency: Through the synergistic effect of the Venturi effect and jet atomization, the carbon dioxide dissolution efficiency is improved and the dissolution saturation is increased;

[0069] The tube body 110 is provided with radially arranged air introduction holes 115, and according to the injection direction of the liquid, the air introduction holes 115 are arranged behind the narrow hole portion 114; there are multiple air introduction holes 115, and the multiple air introduction holes 115 are arranged at intervals along the circumference of the tube body 110; the block 120 is provided with a blocking surface 121 for blocking the jet formed by the liquid, and the blocking surface 121 is a plane, and the center of the blocking surface 121 is perpendicular to the jet formed by the liquid.

The distance between the first end of the connecting rod 130 and the axis of the tube body 110 is smaller than the distance between the second end of the connecting rod 130 and the axis of the tube body 110.

[0071] The liquid valve and the gas valve are both flow regulating electromagnetic valves.

[0072] The inner wall of the narrow hole portion 114 is tapered, and a movable core shaft 150 is provided in the tube body 110. The movable core shaft 150 is a tapered structure that matches the inner wall of the narrow hole portion 114.

[0074] A liquid flow meter is provided in the liquid delivery pipeline and is located between the liquid valve and the venturi tube assembly; a gas flow meter is provided in the carbon dioxide delivery pipeline and is located between the gas valve and the mixing area; a concentration sensor is provided on the bubble water output pipeline 400;

[0075] a pressure sensor, disposed near the narrow hole portion 114;

[0076] The liquid level sensor 500 is disposed in the tank body 200 .

[0077] The above device control method flow:

[0078] Step S1: Parameter reception

[0079] User input via touch screen:

[0080] Target concentration: 3-10g / L (selectable preset gears: low 3-5g / L, medium 5-7g / L, high 7-10g / L)

[0081] Taste selection: fine (droplets 50-100μm), standard (100-200μm), rough (200-300μm)

[0082] Preparation volume: 0.5-5L;

[0083] Step S2: Initialization settings, as shown in Table 1

[0084] Table 1

[0085] Target concentration Liquid valve initial opening Initial valve opening Narrow hole diameter Low 65% 30% 2.2mm middle 55% 50% 1.5mm high 45% 70% 0.8mm

[0086] The control unit calls the initial parameters according to the input parameters:

[0087] For different taste requirements, adjust based on the above:

[0088] Delicate taste: pore diameter reduced by 0.2-0.3mm

[0089] Rough taste: pore diameter increased by 0.2-0.3mm

[0090] Step S3: Fluidics and mixing control

[0091] Liquid enters the Venturi tube under the action of a liquid pump, forming a high-speed jet at the narrow aperture. The flow rate is related to the liquid flow rate and aperture diameter (the higher the flow rate and the smaller the aperture, the higher the flow rate). The jet impacts the blocker and breaks into tiny droplets, forming a large gas-liquid interface. Carbon dioxide is drawn into the negative pressure area of ​​the Venturi tube (-0.02 to -0.05 MPa), where it mixes thoroughly with the droplets and dissolves, forming bubbly water.

[0092] Step S4: Real-time monitoring and calculation

[0093] The control unit collects and calculates the following parameters in real time:

[0094] Actual liquid flow rate Ql (L / min), actual carbon dioxide flow rate Qg (L / min)

[0095] Jet velocity v (m / s): v=4×Ql / (π×d²×60), where d is the aperture of the narrow hole (m)

[0096] Jet impact force F (N): F = 0.1 × ρ × v² × A, where ρ = 1000 kg / m³, A is the force area of ​​the block (m²)

[0097] Current concentration C (g / L): directly measured by the concentration sensor

[0098] Liquid temperature T (°C): used for temperature compensation calculation

[0099] Step S5: Dynamically adjust the strategy

[0100] The control unit calculates the concentration deviation ΔC = C - target concentration and adjusts it according to the following rules:

[0101] When ΔC>0.4g / L (actual concentration is high):

[0102] The valve opening decreases by ΔVg=0.07×ΔC (%), and the adjustment rate is ≤5% / s

[0103] Keep the liquid valve opening and jet parameters unchanged

[0104] If ΔC is still > 0.3g / L for 3 consecutive seconds, increase the liquid valve opening by 3-5%.

[0105] When -0.4g / L≤ΔC≤0.4g / L (deviation is within the allowable range):

[0106] Air valve opening fine-tuning: ΔVg = 0.03×ΔC (%)

[0107] Maintain the stability of the current jet parameters

[0108] The sampling period is extended to 0.5 s / time

[0109] When ΔC < -0.4 g / L (actual concentration is low):

[0110] The air valve opening is increased by ΔVg = 0.09×|ΔC| (%)

[0111] The liquid valve opening is decreased by ΔVl = 0.04×|ΔC| (%)

[0112] If |ΔC| > 0.8 g / L, the aperture of the narrow hole part is synchronously reduced by 0.1 - 0.2 mm

[0113] Step S6: Jet optimization control

[0114] The control unit calculates the jet impact force F every 100 ms and compares it with the target range [Fmin, Fmax]:

[0115] Low concentration mode: Fmin = 1.2 N, Fmax = 1.8 N

[0116] Medium concentration mode: Fmin = 1.8 N, Fmax = 2.5 N

[0117] High concentration mode: Fmin = 2.5 N, Fmax = 3.5 N

[0118] When F < Fmin, adjust according to the following priority:

[0119] The liquid valve opening is increased by 3 - 5% (priority)

[0120] [[ID=CO2]]The aperture of the narrow hole part is reduced by 0.1 - 0.2 mm

[0121] When F > Fmax, perform the opposite adjustment

[0122] Step S7: Temperature compensation

[0123] Compensate the carbon dioxide flow rate based on the liquid temperature T:

[0124] Qg_compensated = Qg_base×[1+(20 - T)×0.018]

[0125] Where 20°C is the reference temperature and 0.018 is the temperature coefficient (for every 1°C decrease in temperature, the CO2 solubility increases by approximately 1.8%) <<

[0126] Step S8: Intelligent learning optimization

[0127] The control unit uses a reinforcement learning algorithm to optimize initial parameters:

[0128] State space: target concentration, temperature, water quality TDS value

[0129] Action space: Liquid valve / gas valve initial opening correction (±5%)

[0130] Reward function: R = 100 - 600 × | final deviation |

[0131] After more than 50 learning sessions, the concentration deviation before the first adjustment dropped from the initial 0.7-0.9 g / L to below 0.4 g / L, and the adjustment time was shortened by more than 30%.

[0132] Step S9: Security Control

[0133] When the carbon dioxide gas source pressure is less than 0.2MPa, a gas replenishment prompt will be issued

[0134] When the liquid flow rate is less than 0.3L / min for 2 seconds, the double valve will be closed and a water shortage warning will be displayed.

[0135] When the mixing chamber pressure is > 0.6MPa, the pressure relief valve will open automatically.

[0136] When a CO2 leak is detected (concentration > 0.5%), the system is shut down and an alarm is activated

[0137] Through the collaborative innovation of structural design and control methods, the present invention achieves efficient preparation and precise regulation of sparkling water. It can be widely used in scenarios such as households, catering, and beverage production, and has significant practical value and market prospects.
