[0034] With the development of electronic technology, related applications have gradually been promoted and popularized. Among them, electronic atomization equipment is an emerging electronic device, also known as electronic cigarettes or electronic smoking utensils. It is a device that simulates the smoking experience by heating the atomizing liquid to generate steam. Generally speaking, it consists of a battery assembly, an atomizer assembly, and an atomizing liquid storage device.

When using electronic atomizing equipment, users often want to know the remaining amount of atomizing liquid stored in the atomizing liquid storage device to facilitate usage planning or prepare to add atomizing liquid in advance.

[0035] In the related art, when determining the remaining amount of atomizing liquid in an electronic atomizing device, it is generally determined by combining the total usage time with the consumption of atomizing liquid per unit time. The result obtained by this implementation method is an estimated value, which has the problem of inaccuracy; on the other hand, some electronic atomizing devices have been added with new atomizing liquid by users, and the amount added cannot be accurately determined, making it difficult to determine the specific situation of the remaining amount of atomizing liquid, affecting the user's experience.

[0036] In view of this, the embodiments of the present application provide an atomization liquid remaining amount detection system and an electronic atomization device, which can accurately and efficiently detect the atomization liquid remaining amount in the electronic atomization device. The system has low construction cost, simple structure, and is easy to miniaturize, which is suitable for the application scenarios of the electronic atomization device. The electronic atomization device includes the above-mentioned atomization liquid remaining amount detection system, and the user experience is better.

[0037] Below, in conjunction with specific drawings, an atomization liquid residual detection system and an electronic atomization device provided in an embodiment of the present application are described in detail.

[0038] The embodiment of the present application provides an atomized liquid remaining amount detection system, which can be applied to the field of electronic equipment technology. Specifically, the atomized liquid remaining amount detection system provided in the embodiment of the present application mainly includes:

[0039] Atomized liquid storage device, detection circuit and processor;

[0040] Wherein, the atomized liquid storage device comprises a first shell, and the first shell is used to store the atomized liquid;

[0041] The detection circuit includes a plurality of detection modules, each of which is used to detect the pressure exerted on the first shell in a certain dimension;

[0042] Each group of the detection modules in the detection circuit is connected to the processor.

[0043] In an embodiment of the present application, there is provided an atomized liquid remaining amount detection system that can accurately and efficiently detect the remaining amount of atomized liquid in an electronic atomization device. The system has a low construction cost, a simple structure, and is easy to miniaturize, and is suitable for the application scenario of the electronic atomization device. The atomized liquid remaining amount detection system in the embodiment of the present application includes an atomized liquid storage device, a detection circuit, and a processor; wherein the atomized liquid storage device is used to store the atomized liquid, and it may include a shell, which is recorded as a first shell in the embodiment of the present application, and the atomized liquid can be stored inside the first shell. The present application does not limit the specific shape of the first shell. In an embodiment of the present application, the detection circuit may include multiple groups of detection modules, each group of detection modules is used to detect the pressure on the first shell in a certain dimension, each group of detection modules in the detection circuit is connected to the processor, and each group of detection modules is used to input the detected pressure data into the processor, and the processor can calculate the resultant force data on the first shell according to the pressure data, and calculate the atomized liquid remaining amount data stored in the first shell through the resultant force data.

[0044] In the embodiment of the present application, there is no restriction on the number of detection modules included in the detection circuit. Exemplarily, in some embodiments, the detection circuit may include three groups of detection modules, and the three groups of detection modules may be arranged on the first shell, and each group of detection modules may detect the pressure exerted on the first shell in one dimension. Among them, the angle between the pressure dimensions detected by any two of the three groups of detection modules is 90 degrees. That is, the pressure dimensions detected by the three groups of detection modules are perpendicular to each other. In this way, the detection circuit can have the ability to test gravity in a three-axis space. Since the relationship between the forces in the three-axis directions is perpendicular to each other, the overall resultant force can be easily calculated. For example, the three groups of detection modules respectively detect the pressure of the first shell in the XYZ axis direction, and the forces in the XYZ axis direction are a, b, and c respectively. Then the resultant force data exerted on the first shell at this time can be expressed as:

[0045]

[0046] The resultant force data on the first shell is actually generated by the weight of the first shell itself and the atomized liquid stored therein, that is, G=mg. Therefore, based on the resultant force data and the weight of the first shell itself, the remaining data of the atomized liquid stored in the first shell can be obtained. In the embodiment of the present application, the detection module can be fixedly connected to the first shell by pasting, and there is no restriction on the specific setting position of the detection module. In terms of circuit connection relationship, each group of detection modules is connected to the processor for transmitting the detected pressure data to the processor, and the remaining data of the atomized liquid can be obtained after calculation in the processor.

[0047] In some embodiments, the present application can also improve the structure of a conventional atomized liquid storage device, using a double-layer structure to store the atomized liquid. Specifically, the atomized liquid storage device may include a two-layer shell, in addition to the aforementioned first shell, it may also include a second shell, the interior of the first shell and the second shell are hollow, the size of the first shell is smaller than the second shell, the first shell is arranged in the second shell, the two form a nested structure, and there is a gap between the two shells, that is, the first shell and the second shell themselves do not contact each other, the atomized liquid can be stored in the first shell, and the detection module can be arranged in the gap between the first shell and the second shell.

[0048] In the embodiments of the present application, there is no limitation on the specific structure of the first shell and the second shell. For example, in some embodiments, the first shell and the second shell can adopt a cylindrical structure. In some embodiments, the first shell and the second shell can also adopt a rectangular parallelepiped structure. Of course, the structure of the first shell and the second shell can also adopt other types, which is not limited by the present application.

[0049] It should be noted that in the embodiments of the present application, the shapes of the first shell and the second shell can be the same, for example, the first shell and the second shell both adopt a rectangular structure, and the proportions of the sides of the rectangular are the same; the shapes of the first shell and the second shell can also be different, for example, the first shell and the second shell both adopt a rectangular structure, but the proportions of the sides of the rectangular are different, or the first shell adopts a cylindrical structure, and the second shell adopts a rectangular structure. The present application does not impose any restrictions on this.

[0050] In particular, in some embodiments, the first shell and the second shell can also use an irregular structure. In addition, in order to facilitate the subsequent setting of the detection module in the gap between the first shell and the second shell, in some embodiments, the spacing distance between the first shell and the second shell can be the same everywhere. In the embodiments of the present application, there is no restriction on the size of the specific spacing distance, which can be flexibly adjusted according to actual needs. It can be understood that by setting the second shell, the installation and arrangement of the detection module can be facilitated, preventing it from being exposed to the outside, and improving the operating stability of the detection circuit.

[0051] In the embodiment of the present application, the detection module of the atomized liquid residual detection system can adopt a pressure sensing unit, and the pressure sensing unit here can be an electronic device for measuring and monitoring various pressure changes, usually including a sensing element and a signal processing circuit, etc., which can convert the pressure change into an electrical signal output. For example, for example, the pressure sensing unit can be a resistance strain gauge. The resistance strain gauge is a sensor that measures the strain of an object by changing its resistance value. It is usually composed of a metal foil. When the object is strained, the resistance strain gauge will produce a corresponding deformation, thereby changing its resistance value. By measuring the change in resistance value, the amount of strain that occurs in the object can be determined. In the embodiment of the present application, the resistance strain gauge can be arranged on the first shell, and the pressure on the first shell is generated by the weight of the first shell itself plus the weight of the atomized liquid residual stored in the first shell. Therefore, the resistance value of the resistance strain gauge can reflect the weight of the first shell and the atomized liquid residual stored in the first shell, and the weight of the first shell itself is known and can be measured in advance, so the weight of the atomized liquid residual stored in the first shell can be obtained, that is, the relevant data of the atomized liquid residual can be obtained. In an embodiment of the present application, each resistance strain gauge can be connected to a processor, and the processor can detect the resistance value of each resistance strain gauge, and then process the remaining amount of atomization liquid of the electronic atomization device.

[0052] In the embodiment of the present application, the pressure sensing unit of the atomized liquid residual detection system can also be a piezoelectric sensor. The piezoelectric sensor is a sensor that uses the piezoelectric effect to measure physical quantities. The piezoelectric effect refers to the phenomenon that certain specific crystals, ceramics or polymers will have uneven charge distribution when external force or pressure is applied, generating voltage. The piezoelectric sensor uses this effect to convert physical quantities such as pressure, force, vibration, etc. into electrical signal outputs, thereby achieving the measurement and monitoring of these physical quantities. In the embodiment of the present application, the piezoelectric sensor can be arranged on the first shell. Similarly, since the pressure on the first shell is generated by the weight of the first shell itself plus the weight of the atomized liquid residual stored in the first shell, the voltage value of the piezoelectric sensor can reflect the weight of the first shell and the atomized liquid residual stored in the first shell, and the weight of the first shell itself is known and can be measured in advance, so the weight of the atomized liquid residual stored in the first shell can be obtained, that is, the relevant data of the atomized liquid residual can be obtained.

[0053] In some embodiments, the detection circuit includes a first pressure sensing unit, a second pressure sensing unit, a third pressure sensing unit, a fourth pressure sensing unit, a fifth pressure sensing unit, and a sixth pressure sensing unit;

[0054] Among them, the first pressure sensing unit and the second pressure sensing unit constitute a group of detection modules, the third pressure sensing unit and the fourth pressure sensing unit constitute a group of detection modules, and the fifth pressure sensing unit and the sixth pressure sensing unit constitute a group of detection modules.

[0055] In the embodiment of the present application, the detection circuit may include three groups of detection modules, and the three groups of detection modules include six pressure sensing units, which are respectively recorded as the first pressure sensing unit, the second pressure sensing unit, the third pressure sensing unit, the fourth pressure sensing unit, the fifth pressure sensing unit and the sixth pressure sensing unit, wherein the first pressure sensing unit and the second pressure sensing unit constitute a group of detection modules, the third pressure sensing unit and the fourth pressure sensing unit constitute a group of detection modules, and the fifth pressure sensing unit and the sixth pressure sensing unit constitute a group of detection modules. There is no restriction on the device selection and installation position of each pressure sensing unit.

[0056] In the embodiment of the present application, the processor can be implemented with reference to any existing mature product, and the present application does not limit this. Specifically, in some embodiments, the processor of the present application may include any one or more processor chips including MCU single-chip microcomputer, FPGA, CPLD, DSP, ARM, etc. For example, the single-chip microcomputer chip can be set to STC12 series single-chip microcomputer chip or STM32 series single-chip microcomputer chip. Of course, the specific chip selection can be flexibly adjusted as needed, and this is not limited in the embodiment of the present application.

[0057] It can be understood that the atomization liquid remaining detection system provided in the embodiment of the present application can accurately and efficiently detect the atomization liquid remaining in the electronic atomization device. The system has low construction cost, simple structure, and is easy to miniaturize, and is suitable for application scenarios of electronic atomization devices.

[0058] The following is an introduction and description of the atomized liquid residual amount detection system provided in the embodiments of the present application in conjunction with specific application examples.

[0059] Please refer to Figure 1 , Figure 1 A schematic diagram of the structure of an atomized liquid storage device provided in an embodiment of the present application is shown. Figure 1 The atomized liquid storage device shown includes a first shell and a second shell. The first shell and the second shell adopt a rectangular parallelepiped structure, wherein the six planes of the first shell, front, rear, left, right, top and bottom, can be recorded as the first plane, the second plane, the third plane, the fourth plane, the fifth plane and the sixth plane.

[0060] In the present application embodiment, for Figure 1In the atomized liquid storage device shown, the pressure sensing unit may adopt a resistance strain gauge. For example, the detection circuit may include a first resistance strain gauge R1, a second resistance strain gauge R2, a third resistance strain gauge R3, a fourth resistance strain gauge R4, a fifth resistance strain gauge R5 and a sixth resistance strain gauge R6; wherein the first resistance strain gauge R1 is arranged at the first plane, the second resistance strain gauge R2 is arranged at the second plane, the third resistance strain gauge R3 is arranged at the third plane, the fourth resistance strain gauge R4 is arranged at the fourth plane, the fifth resistance strain gauge R5 is arranged at the fifth plane, and the sixth resistance strain gauge R6 is arranged at the sixth plane.

[0061] In some embodiments, the atomized liquid remaining amount detection system further includes a power module;

[0062] In the embodiment of the present application, the detection system may also include a power module, which may be a power source carried by the electronic atomization device itself, and the power module may supply power to the relevant components in the detection system. The present application does not limit the specific circuit structure of the power module.

[0063] Reference Figure 2 , Figure 2 FIG. 1 is a schematic diagram showing the circuit principle of a detection circuit provided in an embodiment of the present application. Figure 2 In the detection circuit shown, when a resistance strain gauge is used as a pressure sensing unit, the circuit connection relationship can be: the first end of the first resistance strain gauge R1 is connected to the power module, the second end of the first resistance strain gauge R1 and the first end of the second resistance strain gauge R2 are connected to the second port AIN2 of the processor, and the second end of the second resistance strain gauge R2 is grounded; the first end of the third resistance strain gauge R3 is connected to the power module, the second end of the third resistance strain gauge R3 and the first end of the fourth resistance strain gauge R4 are connected to the third port AIN3 of the processor, and the second end of the fourth resistance strain gauge R4 is grounded; the first end of the fifth resistance strain gauge R5 is connected to the power module, the second end of the fifth resistance strain gauge R5 and the first end of the sixth resistance strain gauge R6 are connected to the first port AIN1 of the processor, and the second end of the sixth resistance strain gauge R6 is grounded.

[0064] In the embodiment of the present application, through the above-mentioned detection circuit, the values ​​measured by the first resistance strain gauge R1 and the second resistance strain gauge R2 are input to the processor through the second port AIN2, and the gravity of the first shell on the Y axis can be measured; the values ​​measured by the third resistance strain gauge R3 and the fourth resistance strain gauge R4 are input to the processor through the third port AIN3, and the gravity of the first shell on the X axis can be measured; the values ​​measured by the fifth resistance strain gauge R5 and the sixth resistance strain gauge R6 are input to the processor through the first port AIN1, and the gravity of the first shell on the Z axis can be measured. In this way, the detection circuit has the ability to test gravity in a three-axis space, and the relationship between the forces in the three-axis directions is perpendicular to each other, so the overall resultant force can be easily calculated. For example, if the forces in the XYZ axis directions are a, b, and c respectively, then the resultant force data at this time is Based on the resultant force data and the weight of the first shell, the remaining amount data of the atomized liquid can be obtained.

[0065] In the embodiment of the present application, in other implementation schemes, the pressure sensing unit may use a piezoelectric sensor.

The first piezoelectric sensor and the second piezoelectric sensor constitute a group of detection modules, the third piezoelectric sensor and the fourth piezoelectric sensor constitute a group of detection modules, and the fifth piezoelectric sensor and the sixth piezoelectric sensor constitute a group of detection modules.

[0066] Reference Figure 3 , Figure 3 FIG. 2 shows a schematic diagram of the circuit principle of another detection circuit provided in an embodiment of the present application. Figure 3 In the detection circuit shown, when a piezoelectric sensor is used as a pressure sensing unit, the circuit connection relationship can be: the first end of the first piezoelectric sensor L1 is connected to the first port AIN1 of the processor, the second end of the first piezoelectric sensor L1 is connected to the second end of the second piezoelectric sensor L2, and the first end of the second piezoelectric sensor L2 is connected to the second port AIN2 of the processor; the first end of the third piezoelectric sensor L3 is connected to the third port AIN3 of the processor, the second end of the third piezoelectric sensor L3 is connected to the second end of the fourth piezoelectric sensor L4, and the first end of the fourth piezoelectric sensor L4 is connected to the fourth port AIN4 of the processor; the first end of the fifth piezoelectric sensor L5 is connected to the fifth port AIN5 of the processor, the second end of the fifth piezoelectric sensor L5 is connected to the second end of the sixth piezoelectric sensor L6, and the first end of the sixth piezoelectric sensor L6 is connected to the sixth port AIN6 of the processor.

[0067] In the embodiment of the present application, through the above-mentioned detection circuit, the first piezoelectric sensor and the second piezoelectric sensor constitute a group of detection modules, which are input to the processor through the first port AIN1 and the second port AIN2, and the gravity of the first shell on the Y axis can be measured; the third piezoelectric sensor and the fourth piezoelectric sensor constitute a group of detection modules, which are input to the processor through the third port AIN3 and the fourth port AIN4, and the gravity of the first shell on the X axis can be measured; the fifth piezoelectric sensor and the sixth piezoelectric sensor constitute a group of detection modules, which are input to the processor through the fifth port AIN5 and the sixth port AIN6, and the gravity of the first shell on the Z axis can be measured. In this way, the detection circuit has the ability to test gravity in a three-axis space, and the relationship between the forces in the three-axis directions is perpendicular to each other, so the overall resultant force can be easily calculated. For example, if the forces in the XYZ axis directions are a, b, and c respectively, then the resultant force data at this time is Based on the resultant force data and the weight of the first shell, the remaining amount data of the atomized liquid can be obtained.

[0068] In some embodiments, the atomized liquid remaining amount detection system further includes an acceleration sensor;

[0069] The acceleration sensor is connected to the processor.

[0070] In the embodiment of the present application, the atomized liquid remaining amount detection system may also include an acceleration sensor, which can be used to detect whether the electronic atomization device is in a stable state. It is understandable that the use environment of the electronic atomization device is relatively complex. If the electronic atomization device is currently in a mobile state, for example, the user is picking it up for use, then affected by the acceleration during movement, the pressure detected by the resistance strain gauge is not only caused by the first shell and the atomized liquid, which will cause the measurement result to be low in accuracy. Therefore, in the embodiment of the present application, an acceleration sensor can be set to detect the mobile acceleration of the electronic atomization device, and according to the acceleration data, the processor can determine whether the electronic atomization device is in a stable state. When in a stable state, the detected atomized liquid remaining amount can be output. For example, the atomized liquid remaining amount detection system may include a display unit, which can be used to display the value of the detected atomized liquid remaining amount, and when the processor determines that the electronic atomization device is not in a stable state, the display unit may not display the content. When the processor determines that the electronic atomization device is in a stable state, the display unit can display the value of the atomized liquid remaining amount. Here, the processor determines whether the electronic atomization device is in a stable state, which can be implemented based on a comparator, converting the signal detected by the acceleration sensor into a voltage or current signal, and outputting a corresponding level signal by comparing it with a predetermined comparison value. For example, when it is detected that the electronic atomization device is in a stable state, a high-level signal is output, and when it is detected that the electronic atomization device is not in a stable state, a low-level signal is output. The processor's control of the display unit can be implemented based on turning on or off the power-on circuit of the display unit, and this application does not limit its specific circuit structure.

[0071] In an embodiment of the present application, an electronic atomization device is also provided, including the aforementioned atomization liquid remaining amount detection system.

[0072] It can be understood that the electronic atomization device provided in the embodiment of the present application can accurately and efficiently detect the remaining amount of atomized liquid, and has a simple structure, is easy to miniaturize, and provides a better user experience.
