Description

Electronic atomization equipment that can analyze the composition and content of the solution

technical field

The invention relates to the technical field of electronic atomization equipment, in particular to an electronic atomization equipment that can analyze the composition and content of a solution.

Background technique

Electronic atomization equipment includes electronic cigarettes, medical drug atomization equipment, and its basic task is to provide a heating process to convert solutions such as liquid smoke or liquid medicine stored in the electronic atomization equipment into vapor, aerosol, vapor or electronic cigarette smoke for users to smoke. Electronic atomization equipment generally includes a power supply unit and an atomizer.

Existing electronic atomization equipment, when its popularity is relatively high, because the atomizer is a consumable product, the demand is relatively large, and it is easy to be replaced by non-authentic atomizers on the market. There is a function mismatch with the genuine power supply device, which is easy to cause failure, and the quality of the solution to be atomized in the non-genuine atomizer is low, which brings a bad experience to consumers. Therefore, an anti-counterfeiting technology for the atomizer is required. The anti-counterfeiting technology of the existing electronic atomization equipment generally adopts chip encryption and other methods, and the disadvantage of chip encryption is that it can be cracked under certain conditions.

In the existing electronic atomization equipment, the solution to be atomized used in the atomizer has different fluidity and different viscosity under different temperature environments. If the external environment changes, such as in the cold outside Under the environment, the fluidity of the solution becomes poor and the viscosity is extremely high, and the atomization unit of the atomizer will absorb and conduct the solution slowly when it is working. If the electronic atomization device continues to follow the original set program If atomization is performed, if the power is not rapidly increased to emit more heat to preheat the solution, it is easy to cause the smoke to be inhaled.

In the existing electronic atomization equipment, the solution to be atomized used in the atomizer, due to the different usage habits of consumers, there are many solutions with different flavors on the market, and the content and concentration of some specific substances such as nicotine are also different. In order to ensure that your health is not affected, for some specific substances such as nicotine, the amount of smoking in a unit time should be limited. Existing electronic atomization equipment does not limit the intake dose of a specific substance in the solution to be atomized, and does not limit the content of the specific substance in the solution itself, so the concentration or content of the specific substance measured by other methods is used. , will not be accurate enough.

The power supply device of the existing electronic atomization equipment can be used with a variety of atomizers of different flavor solutions, and the specific substances and contents of the different flavor solutions are different, so the fluidity and viscosity of the solution are different. The parameters such as temperature and temperature characteristics are also completely different, and the optimal atomization temperature to achieve the best effect of atomization is also different, and the control program of the power supply device is the same, which cannot distinguish atomizers with different flavors. Therefore, after changing to an atomizer with a different flavor, the power supply device of the electronic atomization device in the prior art still atomizes the solution at the same atomization temperature, so the optimal atomization effect cannot be achieved, and the user cannot obtain the best atomization effect. Good atomization experience.

The above-mentioned technical problems collectively require a technology that can be solved by measuring the composition and content of the solution to be atomized.
