Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0044] In addition, the step sequence in the following method embodiments is only an example and not a strict limitation.

[0045] Reference Figure 1-5 In some embodiments, the present invention proposes a non-steady-state liquid quantity measuring component, which is arranged on a non-fixed device. The non-fixed device includes a fixedly installed container, the container is used to hold liquid, and the non-steady-state liquid quantity measuring component is used to measure the liquid height in the container; the non-fixed device refers to a device whose container may move and tilt at an angle during placement and use, such as an atomizer, an electronic cigarette, etc.

[0046] The non-steady-state liquid volume measurement components include:

[0047] The central processing unit 24 is used to process data according to a set program;

[0048] The attitude and acceleration sensor 25 is connected to the central processing unit 24 for detecting setting parameters so that the central processing unit 24 can obtain acceleration and tilt angle;

[0049] The liquid level sensor 22 is used to detect the liquid level in the container. The liquid level sensor 22 is communicatively connected to the central processing unit 24 .

[0050] Specifically, the liquid level sensor 22 is communicatively connected to the central processing unit 24 via a wiring harness 23. In some embodiments, the attitude and acceleration sensor 25 is a gravity accelerometer. When the attitude and movement of the container meet the conditions, the central processing unit 24 determines the actual height of the liquid in the container through the data obtained by the attitude and acceleration sensor 25 and the liquid level sensor 22, which can facilitate the user to more accurately determine the liquid level; and solve the problem that the amount of liquid in the above-mentioned non-fixed container is difficult to measure.

[0051] Furthermore, in some embodiments, the non-fixed device includes a display module, and the central processor 24 is communicatively connected to the display module.

[0052] Specifically, the display module is used to display the measurement results of the non-steady-state liquid quantity measuring component, for example, the measurement results can be notified to the user through lights, electronic display screens, wireless transmission methods, etc.

[0053] The present invention also proposes an atomizer, comprising an atomization bin 1 and a main unit 2, wherein the atomization bin 1 can be detachably inserted into the main unit 2, a central processing unit 24, a posture and acceleration sensor 25 and a liquid level sensor 22 are arranged on the main unit 2, and the liquid level sensor 22 is arranged beside the atomization bin 1.

[0054] Furthermore, in some embodiments, the host 2 includes structural parts and electronic parts, the electronic parts are arranged in the structural parts, the electronic parts include a circuit board 21 and wiring electrodes, the circuit board 21 is electrically connected to the wiring electrodes, and the circuit board 21 controls the power supply to the wiring electrodes; the central processing unit 24 and the attitude and acceleration sensor 25 are arranged on the circuit board 21; the atomization chamber 1 is provided with an atomization component, and the atomization component and the wiring electrodes are electrically connected.

[0055] Specifically, the attitude and acceleration sensor 25 feeds back information to the central processor 24. After the central processor 24 makes a judgment, if the conditions are met, it controls the circuit board 21 to power the wiring electrode, and then powers the atomization component. The circuit board 21 controls the power supply to the atomization component. The atomization component generates heat after power supply, and generates atomized liquid aerosol for user use.

[0056] Furthermore, in some embodiments, a power output module 26 is provided on the circuit board 21, and the power output module 26 is communicatively connected to the central processing unit 24; the atomization assembly includes an electrode and an atomization core, and the electrode and the atomization core are electrically connected, and the power output module 26 controls the power supply to the atomization core.

[0057] Specifically, the power output module 26 is an existing circuit for powering the atomization component. This is the prior art and will not be described in detail here. The power output module 26 powers the atomization core through the wiring electrodes and the electrodes. The atomization core atomizes the atomization liquid to generate an atomization liquid aerosol for the user to use. When the atomizer is working, the power output module can transmit information such as the time, amplitude, frequency, and waveform of the energy output to the central processor. After the central processor obtains the above data, the power output of the power output module 26 is detected by the central processor 24. According to the relationship between the atomizer working time and power data stored in advance and the atomization liquid consumption, the amount of atomization liquid consumed by the atomizer during operation is calculated.

[0058] In some embodiments, the atomization chamber 1 includes a housing, a sealing component, an atomization core and an electrode, and the housing and the sealing component form a container 11 for storing atomized liquid; the host 2 mainly includes structural parts and electronic parts; the structural parts include an upper shell, a lower shell, a sealing silicone, etc.; the electronic parts include a circuit board 21, a liquid level sensor 22 and a battery cell. The liquid level sensor 22 refers to a sensor that can measure the liquid level, which is arranged beside the atomization chamber 1. In this embodiment, a capacitive sensor is used, which is connected to the circuit board 21 through a wiring harness 23.

[0059] The circuit board 21 is an existing device for supporting the normal operation of the atomizer. In some embodiments, the central processing unit 24 and the attitude and acceleration sensor 25 are independently arranged on the substrate of the circuit board 21. The central processing unit 24 is controlled and connected with the circuit board 21, for example, controlling the power supply to the circuit board to achieve the effect of controlling the atomizer; in some embodiments, the circuit board 21 includes a central processing unit 24 and a power output module 26, and the attitude and acceleration sensor 25 is connected to the central processing unit 24 of the circuit board 21; the central processing unit 24 contains a memory.

[0060] In some embodiments, when working, the user inhales through the nozzle of the atomization bin 1. After the gas pressure sensor determines the suction action based on the air pressure change in the host 2, it transmits the information to the central processor 24, or simultaneously transmits it to the power output module 26. The power output module 26 heats the atomization core through the power supply electrode to generate atomized liquid aerosol for the user to use.

[0061] The present application also proposes a non-steady-state liquid quantity measurement method, which is applied to the non-steady-state liquid quantity measurement component mentioned above;

[0062] Methods include:

[0063] S1, the central processor 24 obtains the tilt angle and acceleration of the container according to the posture and acceleration sensor 25 measurement data;

[0064] S2, judging whether the tilt angle and acceleration meet the liquid level measurement requirements respectively;

[0065] S3, if yes, the central processor 24 obtains the current liquid level measurement value as the current liquid level value; if no, the central processor 24 obtains the dynamic liquid level value as the current liquid level value;

[0066] S4. The central processing unit determines whether the liquid level value meets the use requirements.

[0067] Specifically, in the above step S1, the posture represents the tilt angle of the object in the XYZ coordinate system. The posture and acceleration sensor 25 can calculate and measure the tilt angle relative to the Z axis in the coordinate system through the acceleration change. This is a prior art and will not be elaborated here. In some embodiments, the posture situation can be comprehensively judged by the tilt angles in multiple directions. For example, the tilt angles of the object in the ZX plane and the ZY plane can be judged separately to comprehensively judge the tilt of the object. In this embodiment, in order to simplify the description, the offset angle in the XZ plane is used to represent the tilt angle of the device.

[0068] In the above step S2, it is determined whether the tilt angle and acceleration meet the set conditions. If they do, it is determined that the liquid level measurement requirements are met. For example, in this embodiment, the absolute value of the tilt angle α is less than the preset value α 0 When the tilt angle meets the liquid level measurement requirements, the liquid level detection can be performed. 0 is the preset value. In this embodiment, α 0 =15°, at acceleration 0≤a 0 When the acceleration meets the liquid level measurement requirements, the liquid level detection can be performed, where a is 0 Preset value, in this embodiment, a 0 =0.5m / s 2 .

[0069] In the above step S3, the liquid level measurement value is obtained in combination with the liquid level data detected by the liquid level sensor 22; the dynamic liquid level value is calculated in combination with the previous liquid level value and the estimated consumption of the liquid level; in some embodiments, due to the influence of liquid viscosity, when the container has just switched from motion to stillness, part of the liquid may remain on the container wall, affecting the accuracy of the measurement, so it is possible to consider setting a certain stillness time for high-viscosity liquids to ensure that the liquid falls back, therefore, in some embodiments, the acquisition of the liquid level measurement value can add additional judgment conditions, such as whether the state is converted from motion to stillness, and if so, it is determined that the stillness time meets the set time length and is determined to be a still state. In this embodiment, the stillness time t=3s; in some embodiments, the additional judgment condition can directly determine whether the stillness time meets the set time length.

[0070] In the above step S4, in some embodiments, the liquid level height value is compared with the preset value to determine whether the liquid level interval is suitable for the non-fixed device to work; when the liquid level height value H is greater than the preset value h 0 When the actual height of the liquid level is within the liquid level range, it can work normally without worrying about damage to the atomizer, which meets the use requirements; when the liquid level value H is less than or equal to the preset value h 0 ​When the actual height of the liquid level is outside the liquid level range, it is judged that it does not meet the use requirements.

[0071] Furthermore, in step S3, the step of obtaining the liquid level measurement value includes:

[0072] S31, start the liquid level sensor 22 to obtain the liquid level measurement height;

[0073] S32, obtaining a liquid level measurement value according to the liquid level measurement height and the inclination angle.

[0074] In the above step S31, the liquid level measurement height is directly obtained by the liquid level sensor 22 and sent to the central processor 24; the liquid level sensor 22 is a capacitive liquid level sensor.

[0075] In the above step S32, the liquid level measurement value is calculated according to the preset calculation rules and written into the memory of the central processing unit 24; when the non-fixed device is turned to an upright state, the liquid level measured by the liquid level sensor 22 is used as the liquid level measurement value.

[0076] Further, in some embodiments, the step S32 of obtaining the liquid level measurement value according to the liquid level measurement height and the inclination angle comprises:

[0077] S321. Substitute the parameters into the formula Obtain the liquid level measurement value H, where h is the liquid level measurement height, α is the inclination angle, and b is the liquid level width.

[0078] Specifically, in the above step S321, b is the liquid surface width in the coordinate plane, which refers to the width in the horizontal axis direction perpendicular to the vertical coordinate axis Z axis in the coordinate plane. In the present embodiment, b is the width in the X-axis direction in the XZ plane, b is a known parameter, h is a parameter measured by the liquid level sensor 22; α is the inclination angle of the container 11 in the coordinate plane relative to the vertical coordinate axis.

[0079] Furthermore, in some embodiments, in step S3, the step of obtaining a dynamic liquid level value includes:

[0080] S33, obtaining the most recently saved liquid level value;

[0081] S34, calculating the liquid consumption according to the detected working condition of the equipment, where the working condition of the equipment is generated after the most recently saved liquid level value;

[0082] S35. Calculate the dynamic liquid level value by combining the liquid consumption and the liquid level value.

[0083] Specifically, in the above step S33, the most recently saved liquid level value is the liquid level value obtained in step S3 and saved to the central processor 24, which can be directly read.

[0084] In the above step S34, the central processing unit 24 calculates the atomized liquid consumption according to the equipment working conditions of the power output module 26 (output power value and corresponding working time), that is, according to the relationship between the atomizer working time and power data stored in advance and the atomized liquid consumption, the amount of atomized liquid consumed by the atomizer during operation is calculated.

[0085] In the above step S35, the height change of the liquid level is calculated according to the known cross-sectional area of ​​the container and the amount of atomized liquid consumed, and the height change is subtracted from the liquid level measurement value to calculate the dynamic liquid level height value.

[0086] Further, in some embodiments, after step S4 of determining whether the liquid level value meets the use requirements, the following steps are included:

[0087] S5, judging whether the liquid level value, tilt angle and acceleration all meet the use requirements;

[0088] S6. If yes, it is determined to be in normal working state. In normal working state, the central processing unit releases the restriction on the power output module;

[0089] S7, if not, it is determined to be in an abnormal working state. In the abnormal working state, the central processor 24 prohibits the power output module 26 from working.

[0090] Specifically, in the above steps S5-S57, the liquid level interval suitable for non-fixed equipment operation is determined by comparing with the preset value; when the liquid level height value H is greater than the preset value h 0 When the liquid level value H is less than or equal to the preset value h, the atomizer can be operated normally without worrying about damage to the atomizer. 0 When the liquid level value is outside the liquid level range, it is determined that the liquid level is in an abnormal working state, and the central processor 24 prohibits the power output module 26 from working to prevent the atomizer from being damaged when the atomized liquid cannot be supplied to the atomizer in time. In this embodiment, h 0 =1mm; the inclination angle α meets |α|≤α 1 When the tilt angle meets the use requirements, α 1 is the preset value. In this embodiment, α 1 =60°, |α|>α 1It is determined that the tilt angle is not within the corresponding set range and does not meet the use requirements. In an abnormal working state, the central processor prohibits the power output module from working; the acceleration is 0 <a<a 0 When the acceleration meets the use requirements, the central processor does not start the measurement of the liquid level, but judges that the device is in normal working state, and can release the restriction on the power output module, a≥a 0 When the device is in complex motion and is not suitable for operation, the central processor prohibits the power output module from operating in an abnormal working state.

[0091] The present invention proposes a non-steady-state liquid quantity measuring component, atomizer and non-steady-state liquid quantity measuring method. When the posture and movement of the container 11 meet the conditions, the central processing unit 24 judges the actual height of the liquid in the container 11 through the data obtained by the posture and acceleration sensor 25 and the liquid level sensor 22, which can facilitate the user to judge the liquid level more accurately; and solves the problem that the liquid volume in the above-mentioned non-fixed container 11 is difficult to measure.

[0092] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention.
