The disclosure relates to the technical field of electronic vaporizing device, in particular to an electronic vaporizing device capable of analyzing solution composition and content.
An electronic vaporizing device, which includes an electronic cigarette and a medical drug vaporizing device, can provide a heating process of converting a solution (such as cigarette liquid and drug liquid) stored in the electronic vaporizing device into vapor fog, aerosol, steam, or electronic cigarette vapor, for users to use. An electronic vaporizing device usually comprises a battery device and a cartridge.
As the cartridges are consumables and cartridges for famous brands of existing electronic vaporizing devices are in great demand, unauthorized cartridges are now available on the market. The unauthorized cartridges cannot be well functionally adapted to the battery device of the authorized electronic vaporizing device and are prone to failures. Besides, the to-be-vaporized solution of unauthorized cartridges usually has poor quality and may contribute to poor user experience. Thus, an anti-counterfeit technique for cartridges is desired. With respect to the anti-counterfeit technique for cartridges, existing electronic vaporizing devices usually use an encryption chip for anti-counterfeiting. However, the encryption chip for anti-counterfeiting may be decoded under some conditions.
The to-be-vaporized solution of cartridges of existing electronic vaporizing device has different fluidities and viscosities under different temperatures. When the environment temperature changes, for example, when the environment temperature becomes very low, the fluidity of the to-be-vaporized solution is reduced and the viscosity is very high. In such a case, during operation, the absorption and transmission of the to-be-vaporized solution by means of the vaporizing unit of the cartridge is very slow. In such a case, if the electronic vaporizing device performs a vaporization process according to a normal preset program without quickly increasing the power to provide more heat for preheating the solution, the vapor can hardly be produced.
Depending on consumer preferences, the to-be-vaporized solution of cartridge part of existing electronic vaporizing devices on the market has many different flavors, of which the content and concentration of some specific substance such as nicotine are also different. For the sake of health, it is desired to restrict some substance intakes (such as the nicotine intake) per unit time. Though some existing electronic vaporizing devices are capable of restricting the intake of some substance of the vaporization solution, they cannot measure any content of any substance of the solution to facilitate the restriction. Besides, the concentration or content of some substance measured by other methods are not accurate enough.
Usually, the battery device of existing electronic vaporizing devices can be matched with cartridges provided with different flavors of solutions. The different flavors of solutions have different compositions and contents, which results in totally different parameters including fluidity, viscosity, and temperature characteristics. In such a case, in order to achieve optimum vaporizing effect, different solutions need to be vaporized at different optimum vaporizing temperatures. However, the control program of battery device is same, which cannot distinguish the cartridges with different flavors. That is, no matter which flavor is used, the battery device of existing electronic vaporizing devices vaporizes the solutions at a same vaporizing temperature. In such a case, the vaporizing effect and user experience cannot be optimized.
To this end, a technique involving a measurement for compositions and contents of the to-be-vaporized solution is desired.
The purpose of invention is to provide an electronic vaporizing device capable of analyzing solution composition and content, which is provided with a spectral sensor element for overcome the above shortcomings.

The disclosure will be explained in detail in conjunction with the drawings.
During operation, the electronic vaporizing device capable of analyzing solution composition and content according to the disclosure can vaporize the to-be-vaporized solution (including drug liquid and cigarette liquid) stored in the electronic vaporizing device into vapor fog. The spectral sensor of the electronic vaporizing device uses the principle of spectrum analysis on the light passing through the solution. That is, as the absorbance of a certain solution at different wavelengths of visible light (i.e., incident light) can be measured, a spectral absorption curve of the solution can be obtained, with the different wavelengths of the incident light on a horizontal axis and respective absorbance on a vertical axis. Different substances have different molecular structures and further different shapes of specific spectral absorption curves. Thus, solute elements of the solution can be analyzed depending on the obtained spectral absorption curves. In addition, for a same solute element of the solution at different concentrations (i.e., different contents) under different temperatures, the spectral absorption curves have a substantially same waveform but have different positions on the vertical axis. Based on such properties of substances, temperatures and concentrations of solute elements of the solution can be analyzed from the obtained spectral absorption curves.
The disclosure will be further explained in detail in conjunction with the drawings.
