izers are generally activated (“turned on”) by triggering a switch that is connected to an air pressure sensor or by pressing an “on” button on the microvaporizer. Typically, after a microvaporizer is turned on, it does not turn off automatically. It is assumed that the microvaporizer is in use when activated.
A user usually activates the e-cigarette when it is intended to be used. The activation triggers the heating element to start heating and the stored fluid to flow from the tank to the heating element, and produces vapor to be delivered to the user. The commercially available e-cigarettes are typically turned on by pushing a button on the e-cigarette to start the heating element preheating process. A second switch, such as a second button or an airflow switch, is subsequently activated to draw the stored fluid from the tank to the preheated heating element. Because the two steps require separate actions from the user, this two-step process creates a delay between starting the e-cigarette and receiving vapor.
Sometimes, the e-cigarette may be activated unintentionally. If the user accidentally pushes the switch button without noticing, the e-cigarette may continuously draw energy from the battery to power the heating element. The heating element can overheat from not receiving the stored fluid, or can produce undesired vapor using the stored fluid and deplete the stored fluid. The undesired vapor can also cause burning.
It is likely for a user to put an inactivated e-cigarette in his/her pocket to transport the e-cigarette, along with other miscellaneous items. Because of the user's movements, the miscellaneous items can accidently hit the “on” button on the e-cigarette while the user is walking. The user might not notice that the e-cigarette is turned on and continues to walk with the activated e-cigarette in his or her pocket. In the scenario that the heating element does not receive stored fluid from the tank, the user may be burned by the overheated e-cigarette in his or her pocket. In the scenario that the second switch in the e-cigarette is also accidentally activated so that the heating element does receive fluids from the tank and creates vapor, then the user may be burned by the preheated heating element and the vapor produced by the e-cigarette in his or her pocket.

izers are generally activated (“ turned on ”) by triggering a substitution that is connect to an air pressure detector or by pressing an “ on ” clitoris on the microvaporizer. Typically, after a microvaporizer is turned on, it does not twist off automatically. It is assumed that the microvaporizer is in function when activated. 
 A user normally activates the e - cigarette when it is intended to be used. The energizing triggers the heating chemical element to start heating and the store fluid to flow from the tank to the heating chemical element, and produces vapor to be delivered to the exploiter. The commercially available e - cigarettes are typically turned on by pushing a button on the east - cigarette to start the heating element preheating process. A second switch, such as a second button or an airflow switch, is subsequently activated to draw the stored fluid from the tank to the preheated heating element. Because the two steps require separate actions from the exploiter, this two - step process create a delay between start the e - cigarette and receiving vaporization. 
 Sometimes, the e - cigarette may be trip unintentionally. If the user accidentally crusade the switch button without noticing, the e - cigarette may continuously draw energy from the battery to power the heating element. The heating element can overheat from not receive the stored fluid, or can grow undesired vapor using the stored fluid and deplete the stored fluid. The undesired vaporization can also cause burning. 
 It is likely for a user to put an inactivated e - cigarette in his / her pocket to transport the einsteinium - cigarette, along with other miscellaneous item. Because of the user's drift, the miscellaneous token can accidently hit the “ on ” release on the e - cigarette while the user is walk. The user might not notice that the e - cigarette is turned on and continues to walk with the activated e - cigarette in his or her pocket. In the scenario that the heating element does not receive stored fluid from the tank car, the user may be burned by the overheat e - cigarette in his or her pocket. In the scenario that the second substitution in the e - cigarette is also accidentally activated so that the heating element does receive fluids from the tank and creates vapor, then the exploiter may be cauterize by the preheated heating system chemical element and the vapor produced by the e - cigarette in his or her pocket.
