The reasons for the burnt smell of e-cigarettes during use and the solutions are as follows:
Problem with the atomization core
Atomization core charring: The oil-conducting cotton of the heating wire in the atomization core is charred, or the heating wire itself burns out or deforms.
There are bubbles in the atomizing core: This makes it difficult for the liquid to enter and affects the oil guiding.
The rope of the atomization core is too thick: It causes the liquid to enter the interior of the atomization core at a too slow speed.
The newly replaced atomizing core was not fully lubricated: After adding the liquid, the newly replaced atomizing core was not left flat for a few minutes, resulting in a burnt smell in the first few mouthfuls of smoke.
The atomization core's lifespan is exhausted: The atomization core is a consumable item, with a lifespan generally ranging from 7 to 28 days. Prolonged use will lead to a decline in performance.
The problem of e-liquid
Poor quality of e-liquid: The use of inferior raw materials or inappropriate formulas causes the e-liquid to have a pungent or abnormal smell.
High viscosity of e-liquid: Poor fluidity causes the oil-absorbing cotton to not conduct oil smoothly.
High sugar/sweetener content in e-liquid: It causes carbon deposits on the oil-absorbing cotton, resulting in a burnt smell when smoking.
The level of the e-liquid is too low: There is too little e-liquid in the atomization chamber, resulting in dry burning.
Equipment problem
Battery issue: The battery is aging and unable to provide sufficient power. The heating chip fails to function properly, resulting in a burnt smell in the smoke and water.
The power setting is too high: If the power setting of the equipment is too high, the heat generated by the heating wire exceeds the oil conduction speed, causing the oil conduction cotton to fail to supply the e-liquid in time, and the heating wire burns dry, resulting in a burnt smell.
Operational problem
Incorrect inhalation method: Inhaling too quickly, too deeply or too vigorously leads to incomplete combustion of the smoke and water, resulting in a burnt smell.
Failure to add e-liquid in time: During use, it was not paid attention to keeping the e-liquid at a certain level, resulting in dry burning.
Replace the atomization core
When it is found that the atomization core is charred or its service life is exhausted, a new atomization core should be replaced in time.
When replacing, carefully remove the old atomizer core as instructed in the electronic cigarette product manual, and then install the new atomizer core.
After installing the new atomizer core, let it stand in the e-cigarette device for a few minutes to allow the oil-conducting material to fully absorb the e-cigarette liquid before starting to use it.
Clean the atomization core
If the atomization core only has slight carbon deposits or a small amount of impurities affecting the oil conduction, its normal function can be restored through cleaning.
For some detachable and cleanable atomizing cores, first remove them from the e-cigarette device, rinse them with warm water to remove surface dirt and some carbon deposits, then let them dry naturally and reinstall them.
Adjust the power of the equipment
If the power setting of the e-cigarette device is too high, the power should be appropriately reduced.
Generally speaking, you can reduce the power by 2 to 3 watts each time, then try suction and observe whether the burnt smell lessens. However, it should be noted that too low power may affect the amount of smoke and the taste. A suitable balance point needs to be found.
Check and add e-liquid
Open the oil tank of the e-cigarette and check the liquid level of the e-cigarette liquid. If the liquid level is too low, an appropriate amount of e-liquid should be added in time to ensure that the atomization core can be fully immersed in the e-liquid.
After adding the e-liquid, wait for a few minutes to allow the e-liquid to fully penetrate the atomizing core before suction.
Change the brand or flavor of the e-liquid
If you suspect that the burnt taste is caused by the e-liquid, you can try changing to a different brand or flavor of e-liquid.
When choosing a new e-liquid, you can check the product's ingredient list and user reviews to select one with good quality and moderate fluidity.
Check the battery and replace it
If you suspect that the burnt smell is caused by battery issues, you can check whether the battery is aged or unable to provide sufficient power.
If there are any problems, a new genuine battery should be replaced in time.
Adjust the inhalation mode
Learn and adopt the correct inhalation method, inhale slowly and evenly, allowing the smoke and water to evaporate fully during the heating process, thereby obtaining a purer taste.
