[0028] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system or device that includes a series of steps or units is not limited to the listed steps or units, but optionally includes steps or units that are not listed, or optionally includes other steps or units inherent to these processes, methods or devices.

[0030] The atomizer can atomize the atomization matrix and produce the corresponding mist. The working temperature of the atomizer has a huge impact on the overall performance of the atomizer. Different electronic control schemes largely determine the working temperature, but there is currently no effective method to determine the best electronic control scheme.

[0031] In the related art, different electronic control schemes are tested one by one using an atomizer, which, on the one hand, will increase the product development cycle of the atomizer, and on the other hand, will increase material consumption and testing costs, thereby reducing product development efficiency.

[0032] Based on this, the present application proposes to construct a simulation model of the atomizer, set the power input of the simulation model according to different electric control schemes, and obtain the temperature change result corresponding to each electric control scheme; then select at least one better electric control scheme from at least two temperature change results, so that different electric control schemes can be quickly compared without conducting actual tests on the atomizer, and a better electric control scheme can be selected, thereby improving R&D efficiency and reducing the cost of atomizer materials consumed in actual tests. Please refer to any of the following embodiments for details.

[0033] See also Figure 1 , Figure 1 1 is a flow chart of an embodiment of a method for determining an electric control scheme provided by the present application. The method comprises:

[0034] Step 11: Obtain at least two different electronic control schemes for the atomizer.

[0035] In some embodiments, multiple electric control schemes can be planned in advance according to the specifications of the atomizer, such as 2 electric control schemes, 3 electric control schemes, 4 electric control schemes, 5 electric control schemes, 6 electric control schemes, 7 electric control schemes, 8 electric control schemes, 10 electric control schemes, 15 electric control schemes or 20 electric control schemes.

[0036] For example, the electronic control scheme A includes controlling the atomizer to work at power 1 in the first time period, controlling the atomizer to work at power 2 in the second time period, controlling the atomizer to work at power 3 in the third time period, and controlling the atomizer to work at power 4 in the fourth time period. Among them, power 1, power 2, power 3 and power 4 are only examples, and power 1, power 2, power 3 and power 4 can be the same or different. That is, the electronic control scheme mainly controls the power of the heating component to make the heating component generate a corresponding temperature.

[0037] Step 12: Set the power input of the simulation model of the atomizer according to each electric control scheme, and obtain the temperature change result corresponding to each electric control scheme.

[0038] In some embodiments, a simulation model can be constructed by using corresponding simulation software in combination with the geometric structure and electrical parameters of the atomizer. Each electrical control scheme is then input into the simulation software, and the simulation model uses each electrical control scheme to set the power input to achieve the atomization operation of the atomizer, thereby obtaining the temperature change result corresponding to each electrical control scheme. The temperature change result is mainly reflected in the temperature change of the heating component in the atomizer within the time of the set power input of the simulation model.

[0039] Step 13: Select at least one better electrical control scheme from at least two temperature change results.

[0040] In some embodiments, the simulation model can be used to set the power input according to each electric control scheme, so that each electric control scheme corresponds to a temperature change result.

[0041] In some embodiments, at least one better electric control scheme can be selected by comparing temperature information such as heating rate, steady-state temperature, and maximum temperature in each temperature change result.

[0042] After selecting at least one preferred electric control scheme, one of the electric control schemes can be set in the atomizer, and the atomizer can subsequently use the electric control scheme to control the atomizer to perform atomization operations. In some embodiments, the best electric control scheme can be selected from at least one preferred electric control scheme. The best electric control scheme is set in the atomizer, and the atomizer can subsequently use the electric control scheme to control the atomizer to perform atomization operations.

[0043] In this embodiment, a simulation model of the atomizer is constructed, and the power input of the simulation model is set according to different electric control schemes to obtain the temperature change result corresponding to each electric control scheme; then, at least one better electric control scheme is selected from at least two temperature change results, so that different electric control schemes can be quickly compared without conducting actual tests on the atomizer, and a better electric control scheme can be selected, thereby improving research and development efficiency and reducing the cost of atomizer materials consumed in actual tests.

[0044] In some embodiments, see Figure 2 , the simulation model is constructed using the following process:

[0045] Step 21: A solution domain is formed based on the geometric structure of the atomizer, and the solution domain includes a fluid domain and a solid domain.

[0046] In some embodiments, the physical field can be set in the area where the physical field is applied, and the area that does not need to be calculated should be removed from the solution domain to reduce the number of networks and reduce the calculation cost. For example, when calculating the conductor current and potential distribution in the current field, the grounding electrode part can be removed from the solution domain, and only the zero potential condition is required.

[0047] In some embodiments, see Figure 3 , step 21 may be the following process:

[0048] Step 211: Obtain the fluid domain and solid domain corresponding to the atomizer.

[0049] The fluid domain is obtained based on the internal flow channel structure of the atomizer, and the solid domain is obtained based on the geometric structure of the heating component of the atomizer.

[0050] In some embodiments, the fluid domain is obtained only by the internal flow channel structure of the atomizer, and the solid domain is obtained only by the geometric structure of the heat-generating component of the atomizer.

[0051] Step 212: geometrically combine the fluid domain and the solid domain to form a solution domain.

[0052] Step 22: Set the electrical field properties of the atomizer's heating component.

[0053] In some embodiments, at least one electric field property including current type, current calculation domain, positive and negative polarity, and power supply initial potential may be set.

[0054] The current calculation domain includes at least one of the material, density, thermal conductivity, electrical conductivity, specific heat of the electrodes and heating surfaces in the heating component, and the area size of the heating surface.

[0055] In some embodiments, the electric field properties include at least one of the material, density, thermal conductivity, electrical conductivity, specific heat of the electrodes and the heating surface in the heating component, and the area size of the heating surface.

[0056] In some embodiments, the parameters of the electrodes and the heating surface in the heating component are as shown in Table 1:

[0057] Table 1 Electrode and heating surface material parameters

[0058]

[0059]

[0060] Step 23: Set the fluid field properties of the fluid domain and the thermal field properties of the solid domain.

[0061] In some embodiments, at least one thermal field property of the heat-generating surface emissivity and initial temperature corresponding to the solid domain is set.

[0062] In some embodiments, at least one fluid field property of the flow medium, fluid inlet form, pressure magnitude, fluid outlet form, flow rate, turbulence model and air initial temperature corresponding to the fluid domain is set.

[0063] In one application scenario, the flow medium can be set to air, the fluid geometry inlet adopts the pressure inlet form, the pressure is set to atmospheric pressure, the fluid geometry outlet adopts the flow outlet form, and the flow rate is set to 18.3ml / s based on the actual value of the human body inhaling the atomized liquid. The turbulence model can choose k-ε, k-omega, Reynolds stress and other models. For the atomizer, the k-omega model can better capture the flow characteristics of air in the complex space inside the atomizer, so the turbulence model can be set to the k-omega model. The initial air temperature can be set to 273.15K.

[0064] Step 24: Set the solution method for the solution domain based on the electrical field properties, fluid field properties, and thermal field properties to form a simulation model.

[0065] After the electrical field properties, fluid field properties, and thermal field properties are set, the solution method for the solution domain can be set, and the simulation model is basically built. The corresponding electrical control scheme can be input into the simulation model to simulate the power input of the atomizer.

[0066] See also Figure 4 , Figure 4 1 is a flow chart of another embodiment of the method for determining the electric control scheme provided by the present application. The method includes:

[0067] Step 41: Obtain at least two different electrical control schemes for the atomizer.

[0068] Step 41 has the same or similar technical solution as any embodiment of the present application and will not be described in detail here.

[0069] Step 42: Mesh the fluid domain and the solid domain.

[0070] In some embodiments, the solution domain (solid domain + fluid domain) is meshed, the meshing method uses the "physical field controlled mesh" form, the mesh size is selected as "extremely fine", and the meshing is completed. Among them, more mesh units mean a more accurate approximate solution in the subsequent step.

[0071] Step 43: Combine each electric control scheme and use the transient mode to iteratively solve each grid to obtain the temperature change result corresponding to each electric control scheme.

[0072] Step 44: Select at least one better electrical control scheme from at least two temperature change results.

[0073] In some embodiments, see Figure 5 , step 44 may be the following process:

[0074] Step 441: Compare the highest temperature in each temperature change result with the highest allowable temperature to obtain at least one target temperature change result; wherein the highest temperature in the target change result is lower than the highest allowable temperature.

[0075] In some embodiments, different electrical control schemes result in different maximum temperatures when the heating component generates heat. Therefore, it is necessary to compare the maximum temperature in each temperature change result with the maximum allowable temperature to screen out at least one target temperature change result whose maximum temperature is lower than the maximum allowable temperature.

[0076] In some embodiments, the heating element of the atomizer is usually in the form of a film, so the heat is generated in the form of surface heating. Therefore, the above-mentioned maximum temperature refers to the highest local temperature of the heating surface at the corresponding time.

[0077] In some embodiments, the maximum allowable temperature is 350 degrees Celsius.

[0078] Step 442: Select at least one preferred temperature change result from at least one target temperature change result, and determine the electric control scheme corresponding to the preferred temperature change result as the preferred electric control scheme.

[0079] In some embodiments, the temperature change result involves a heating rate and / or a steady-state temperature, etc. At least one preferred temperature change result may be selected from at least one target temperature change result according to the heating rate and / or the steady-state temperature.

[0080] For example, the heating rate in each target temperature change result is calculated, and the partial target temperature change results with a large heating rate are preferentially selected. Then, the steady-state temperatures in the partial target temperature change results are compared, and finally, the target temperature change result with the highest temperature in the steady-state time is determined as the better electric control solution.

[0081] In some embodiments, the target temperature change result with the fastest heating rate within a preset time and the highest temperature in steady state among several target temperature change results can be determined as the optimal temperature change result, and the electrical control scheme corresponding to the optimal temperature change result can be determined as the optimal electrical control scheme.

[0082] For example, the heating rate in each target temperature change result is calculated, and the target temperature change result with a large heating rate is preferentially selected as the better temperature change result.

[0083] For example, the steady-state temperature of each target temperature change result is calculated, and the target temperature change result with the highest temperature during the steady-state time is determined as the better electric control solution.

[0084] In an application scenario, after obtaining at least one target temperature change result, at least one target temperature change result can be displayed on a display interface, and a corresponding selection option can be provided. In response to the selection condition set in the selection option, at least one optimal temperature change result is automatically selected from at least one target temperature change result according to the corresponding selection logic. Among them, the selection conditions include the fastest heating rate and the best temperature in steady state. Further, after selecting at least one optimal temperature change result, the at least one optimal temperature change result and its corresponding electric control scheme are displayed.

[0085] In an application scenario, after obtaining at least one target temperature change result, in response to a selection condition, at least one optimal temperature change result is automatically selected from the at least one target temperature change result; wherein the selection condition includes the fastest heating rate and the best temperature in steady state. Further, after selecting the optimal temperature change result, the optimal temperature change result and its corresponding electric control scheme are displayed. That is, in this application scenario, the optimal temperature change result and its corresponding electric control scheme are directly displayed.

[0086] In this embodiment, a simulation model of the atomizer is constructed to simulate the power input of the atomizer according to different electrical control schemes, and the temperature change result corresponding to each electrical control scheme is obtained; then the best electrical control scheme is selected from at least two temperature change results, and different electrical control schemes can be quickly compared without conducting actual tests on the atomizer, and the optimal electrical control scheme can be selected, thereby improving research and development efficiency and reducing the atomizer material cost consumed in actual tests.

[0087] Furthermore, the optimal electric control scheme is selected by comparing the maximum allowable temperature, the heating rate and the temperature during the steady-state time, thereby ensuring that the electric control scheme is most suitable for the atomizer.

[0088] See also Figure 6 , Figure 6 1 is a flow chart of another embodiment of the method for determining the electric control scheme provided by the present application. The method includes:

[0089] Step 61: Obtain at least two different electrical control schemes for the atomizer.

[0090] Step 62: Simulate the power input of the atomizer by controlling the simulation model of the atomizer according to each electric control scheme, and obtain the temperature change result corresponding to each electric control scheme.

[0091] Steps 61 to 62 have the same or similar technical solutions as any embodiment of the present application and will not be described in detail here.

[0092] Step 63: Compare the highest temperature in each temperature change result with the highest allowable temperature to obtain at least one target temperature change result; wherein the highest temperature in the target change result is lower than the highest allowable temperature.

[0093] In some embodiments, at least two temperature change results may be displayed on the display interface.

[0094] In some embodiments, a corresponding temperature change curve may be displayed according to each temperature change result. The temperature change curve is related to time, so that the user can intuitively know the corresponding temperature change when the atomizer works according to each electronic control scheme.

[0095] Step 64: In response to a selection condition, select at least one preferred temperature change result from at least one target temperature change result, and determine the electric control scheme corresponding to the preferred temperature change result as the preferred electric control scheme; wherein the selection condition includes the fastest heating rate and / or the preferred temperature in steady state.

[0096] In some embodiments, the user can make a selection on the display interface, select the target temperature change result with the best heating rate and temperature in steady state as at least one preferred temperature change result, determine the electric control scheme corresponding to at least one preferred temperature change result as the preferred electric control scheme for storage, so that when writing the electric control scheme to the physical atomizer, one of the at least one preferred electric control schemes is written into the physical atomizer. That is, the manual selection instruction is received, and the target temperature change result corresponding to the manual selection instruction is used as the preferred temperature change result.

[0097] In some embodiments, in response to a selection condition, at least one preferred temperature change result is automatically selected from at least one target temperature change result, and the electrical control scheme corresponding to the at least one preferred temperature change result is determined as the preferred electrical control scheme; wherein the selection condition includes the fastest heating rate and / or the preferred temperature in steady state.

[0098] In some embodiments, in response to a selection condition, the best temperature change result is automatically selected from at least one target temperature change result, and the electrical control scheme corresponding to the best temperature change result is determined as the best electrical control scheme; wherein the selection condition includes the fastest heating rate and / or the best temperature in steady state.

[0099] In some embodiments, the best electrical control scheme may be selected and stored for each model of physical atomizer in the above manner.

[0100] In an application scenario, combining the above Table 1 and the following Table 2, Figure 7 , Figure 8 , Fig. 9 , Fig.10 and Fig.11 To explain:

[0101] In the temperature design stage of the heating component, multi-physics field coupling calculation and analysis methods are introduced, and the electronic control scheme is optimized through iterative calculation through simulation, so as to achieve the purpose of controlling the temperature of the heating component. First, the internal flow channel of the atomizer geometry is extracted, and then the flow channel geometry is combined with the heating component geometry to form a solution domain. For example, the geometry of the atomizer is as follows: Figure 7 and Figure 8 As shown, the heating element F is Fig. 9 As shown. The geometric structure of the atomizer has a corresponding geometric structure and an internal flow channel. The atomized matrix enters from the inlet I, is heated and atomized at the heating element F of the heating component to form an aerosol, and then the aerosol flows to the outlet O. And the heating element F of the heating component includes an electrode D and a metal heating surface M. When the electrode D is energized, the metal heating surface M generates heat to atomize the atomized matrix near the metal heating surface M. The solution domain is then meshed, and the electrical, thermal, and fluid mechanics multi-physical fields are set and solved respectively to obtain the corresponding output power scheme. In this embodiment, the materials and parameters of the heating component electrode D and the heating surface are shown in Table 1, and the electrical control scheme is shown in Table 2. In some embodiments, the heating component is in the form of a film.

[0102] Table 2 Summary of electronic control scheme

[0103]

[0104]

[0105]

[0106] Steps:

[0107] The internal flow channel of the atomizer geometric structure is extracted using ANSYS SpaceClaim software. The internal flow channel structure (fluid domain) is obtained and combined with the heat-generating component geometric structure (solid domain). The resulting structure is then imported into the Comsol Multiphysics software for meshing. The electrical, thermal and fluid mechanics multi-physics fields are set and solved respectively.

[0108] Specifically, the DC model is selected for current, the current calculation domain, i.e., the electrode and heating component area, the material is selected (see Table 1 for material parameters), the positive and negative poles are set, the electric control scheme (Table 2) is input in the form of a piecewise function, the initial voltage of the battery is set to 0V, and the electric field part is set.

[0109] And the extracted fluid domain and solid domain are set separately, the fluid domain flow medium is set to air, and the fluid geometry inlet and outlet are set. In order to simulate the real suction state, the inlet adopts the pressure inlet form, the pressure is set to atmospheric pressure, and the outlet adopts the flow outlet form. The flow rate is set to 18.3ml / s according to the real value when the atomized liquid is inhaled. The turbulence model can choose k-ε, k-omega, Reynolds stress and other models. For the inhalation electronic atomizer, the k-omega model can better capture the flow characteristics of air in the complex space inside the atomizer. Therefore, the turbulence model is set to the k-omega model, and the initial air temperature is set to the normal temperature of 273.15K. The fluid field part is set. The heating surface of the heating component exchanges heat with the fluid domain, and the convective heat transfer coefficient will automatically match the fluid velocity software. The emissivity of the heating surface is set to 0.9, and the initial temperature is set to the normal temperature of 273.15K. The thermal field part is set.

[0110] And the solution domain (solid domain + fluid domain) is meshed. The meshing method uses the "physical field controlled mesh" form, and the mesh size is selected as "extremely fine". The meshing is completed.

[0111] The solution method adopts transient mode, iterative solver, the solution start time is set to 0 seconds, the end time is set to 4 seconds, the time step is set to 0.01s, and the solution begins.

[0112] According to the above steps, the temperature change curves corresponding to 8 different electronic control schemes are obtained, such as Fig.10 and Fig.11 As shown. It can be seen that Scheme 4 has the characteristics of rapid heating and high temperature in steady state, and is the best among the 8 schemes. Scheme 4 can be used as the actual electronic control scheme of the atomizer.

[0113] In one application scenario, after constructing a simulation model of the atomizer, an initial electric control scheme is input, and the simulation model is used to work according to the initial electric control scheme to obtain the corresponding temperature change result. Further, the initial electric control scheme is adjusted to change the corresponding time power parameters therein to form a new electric control scheme, and then the simulation model is used to work according to the new electric control scheme to obtain the corresponding temperature change result. In this iteration, the temperature change results corresponding to multiple electric control schemes can be obtained, and then they are screened according to the above screening method to obtain the best electric control scheme.

[0114] In some embodiments, after constructing a simulation model of the atomizer, an initial electric control scheme is inputted, and the simulation model is used to work according to the initial electric control scheme to obtain a corresponding temperature change result. Further, the temperature change result is checked to see if it meets the requirements. If it does not meet the requirements, the initial electric control scheme is adjusted to change the corresponding time power parameters therein to form a new electric control scheme, and then the simulation model is used to work according to the new electric control scheme to obtain a corresponding new temperature change result, and the new temperature change result is checked to see if it meets the requirements, and the process is repeated until an electric control scheme that meets the requirements is found. The electric control scheme that meets the requirements is used as the best electric control scheme for the atomizer.
