Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application will be further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the present application.
In one embodiment, as shown in fig. 1-4, an electronic atomizing device is provided, comprising:
a housing 10, a nebulizer 20, a detection electrode 30, and a capacitance detection module 40; the atomizer 20 is connected with the shell 10, and a tobacco tar storage body 21 is arranged in the atomizer 20; the detection electrode 30 is disposed within the tobacco rod storage body 21 or outside the tobacco rod storage body 21, the detection electrode 30 forming a capacitor with the housing 10.
As an example, the atomizer 20 connected with the housing 10 may include: the atomizer 20 may be fixedly disposed within the housing 10, in which case the detection electrode 30 is also disposed within the housing 10, the detection electrode 30 and the housing forming a capacitor. In a specific embodiment, a recess is formed in the housing 10, the tobacco tar storage body 21 in the atomizer 20 is disposed in the recess of the housing 10, and the rest of the tobacco tar storage body may not be disposed in the housing, where the detection electrode 30 is also disposed in the housing 10, and the detection electrode 30 and the housing form a capacitor. The specific positional relationship between the atomizer 20 and the housing 10 is not limited in this application, and it is sufficient to ensure that the detection electrode 30 and the housing 10 form a capacitor.
The capacitance detection module 40 is configured to detect a capacitance value of the capacitor, and determine an amount of smoke in the smoke storage 21 according to the capacitance value.
In particular implementations, the atomizer 20 generally further comprises: a heating element 22, the heating element 22 being disposed within the tobacco tar storage body 21, the heating element 22 being for atomizing tobacco tar within the tobacco tar storage body 21. The heating elements 22 are elements provided in the electronic atomizing device. To enable the capacitance detection module 40 to detect the capacitance value of the capacitor, in one embodiment, as shown in fig. 1 and 2, the capacitance detection module 40 is connected to the detection electrode 30; the housing 10 is grounded. The detection electrode 30 and the heating element 22 are separately provided in the electronic atomizing device.
In another implementation, as shown in fig. 3 and 4, one end of the heating element 22 is connected to the detection electrode 30, the other end is connected to a power source, and the capacitance detection module 40 is connected to the detection electrode 30 through the heating element 22. The embodiment of fig. 3 and 4 can save wiring in the electronic atomizing device (the embodiment of fig. 1 and 2 requires wiring for the heating element 22 and the detection electrode 30, respectively, and fig. 3 and 4 only require wiring for the heating element 22) compared with the embodiment of fig. 1 and 2.
The medium between the detection electrode 30 and the housing 10 may include 3 cases of tobacco tar (tobacco tar storage 21 is filled with tobacco tar), tobacco tar and air (tobacco tar in the tobacco tar storage 21 is not filled), or air (tobacco tar in the tobacco tar storage 21 is not filled). Since the dielectric constants of the tobacco tar and air are different, as the tobacco tar in the tobacco tar storage body 21 decreases, the ratio of the tobacco tar to air in the tobacco tar storage body 21 changes, which results in a corresponding change in the capacitance value of the capacitor.
Wherein, air and tobacco tar are arranged between the detection electrode 30 and the shell 10, and the capacitance calculation formulas of the air and the tobacco tar are respectively as follows:
wherein: c (C) 1 Capacitance value of the air area; c (C) 2 Capacitance value of the liquid region; epsilon 1 Is the dielectric constant of air; epsilon 2 Is the dielectric constant of the liquid; h is a 1 Is the height of the air in the tobacco tar reservoir 21; h is a 2 Is the height of the tobacco tar in the tobacco tar storage 21; r is R y Relative radius for the housing assembly; r is R x Is the electrode radius.
The capacitance value of the capacitor formed by the detection electrode 30 and the case 10 (corresponding to C 1 And C 2 Parallel) is:
from the above calculation formula, it can be seen that: when the size of the whole structure is unchanged, the capacitance C is in a corresponding relation with the height of the air area and the height of the liquid area, namely when the liquid level is changed, the capacitance C is changed immediately, so that the current liquid level can be judged according to the capacitance C.
As an example, determining the amount of smoke in the smoke store 21 from the capacitance value may specifically include:
calculating the height of the tobacco tar region in the tobacco tar storage body according to the capacitance value and the corresponding relation between the height of the tobacco tar region and the height of the air region in the tobacco tar storage body;
and obtaining the tobacco tar amount according to the height of the tobacco tar area.
Specifically, the present capacitance value of the capacitor is detected by the capacitance detection module 40. While for a certain electronic atomizing device the size of the tobacco rod storage body 21 is fixed, i.e. the height of the tobacco rod storage body is fixed, assuming H, the height of the tobacco rod storage body is equal to the sum of the tobacco rod height and the air height, i.e. h=h 1 +h 2 . The current capacitance value can be deformed into:
only the smoke height h in the above formula 1 It is unknown that the smoke height, i.e. the smoke amount in the smoke storage body, can be calculated and obtained according to the formula.
As another example, determining the amount of smoke in the smoke store 21 from the capacitance value may specifically include:
searching in a preset chart according to the capacitance value to determine a target interval in which the smoke amount corresponding to the capacitance value is located, and taking the target interval as the smoke amount in the smoke storage body, wherein the preset chart comprises the corresponding relation between the capacitance value and each interval of the smoke amount.
Specifically, as another embodiment, in order to quickly inform the user of the amount of tobacco tar in the tobacco tar storage body, two capacitance values may be stored in advance, that is, a capacitance value when the tobacco tar storage body is full of tobacco tar, and a capacitance value when the tobacco tar storage body is full of air. And then establishing a corresponding chart according to the two capacitance values, dividing the tobacco tar quantity corresponding to the two capacitance values into a plurality of sections, wherein each section corresponds to the percentage of tobacco tar in the tobacco tar storage body. Exemplary partitions of the amount of tobacco tar into 5 intervals: 0-20%, 20-40%, 40-60%, 60-80%, 80-100%, and determining the corresponding capacitance values of the two endpoints of each interval. When the device is used, the section where the current capacitance value is located can be determined according to the current capacitance value of the detection capacitor, so that the section where the tobacco tar amount in the current tobacco tar storage body is located is determined.
As yet another example, determining the amount of smoke in the smoke store 21 based on the capacitance value may specifically include:
and calculating the amount of smoke in the smoke storage body according to the current capacitance value, the preset capacitance value when the smoke storage body is full of smoke and the capacitance value when the smoke storage body is full of air.
Wherein Q represents the amount of tobacco tar in the tobacco tar storage body, C represents the current capacitance value of the capacitor, C Full of Representing the capacitance value at full tobacco tar, C 0 Indicating the capacitance value when all of the smoke reservoir 21 is air.
In the electronic atomizing device, the detection electrode is arranged in the tobacco tar storage body or outside the tobacco tar storage body, and the capacitor is formed by the detection electrode and the shell of the electronic atomizing device. The capacitance value of the capacitor will change with different media between the detection electrode and the housing, i.e. the capacitance value will change with the amount of tobacco tar and air between the detection electrode and the housing, for example, the amount of tobacco tar will decrease, the amount of tobacco tar between the detection electrode and the housing will decrease, the amount of air will increase, and the capacitance value will change correspondingly due to the different dielectric constants of tobacco tar and air. Therefore, the shell of the electronic atomization device and the detection electrode are utilized to form the capacitor, the amount of tobacco tar in the tobacco tar storage body is detected, and compared with the prior art, the device is simpler in structure and lower in cost by arranging two electrodes to be close to the tobacco tar.

The heating element 22 is also grounded through a second power switch 60. The enabling terminals (i.e., control terminals) of the first power switch 50 and the second power switch 60 are respectively connected to the capacitance detection module 30.

At this time, the capacitance detection module 30 detects the capacitance value of the detection electrode 30, thereby obtaining the capacitance value of the capacitor composed of the detection electrode 30 and the case 10.

Based on the above embodiment, as shown in fig. 8 and 9, the capacitance detection module 40 includes: the capacitive detection chip 41 and the processor 42, one end of the capacitive detection chip 41 is connected with the detection electrode 30, and the other end is connected with the processor 42; the capacitance detection chip 41 is configured to detect a capacitance value of the capacitor, and transmit the capacitance value to the processor 42, and the processor 42 is configured to determine an amount of smoke in the smoke storage 21 according to the capacitance value. The processor 42 in this embodiment is adapted to be connected to the enable terminal of the corresponding power switch, as shown in fig. 8 and 9.

In order to ensure the accuracy of the detection result, the electronic atomization device of the embodiment further includes a triaxial sensor, and the triaxial sensor can detect the inclination angle of the tobacco tar storage body 21, so that when the tobacco tar storage body 21 is in a horizontal state (i.e., the detection electrode 30 is perpendicular to the liquid level of tobacco tar in the tobacco tar storage body 21), the problem that the detection result of the capacitor is inaccurate when the electronic atomization device is in the inclination angle is avoided.
