Atomizers and Electronic Atomizers

CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims the priority of the Chinese patent application filed on March 11, 2021 with the application number 202120513630.4 and the invention titled "Atomizer and Electronic Atomizer", the entire contents of which are incorporated herein by reference middle.

technical field

The embodiments of the present application relate to the technical field of electronic atomization, and in particular, to an atomizer and an electronic atomization device.

Background technique

There are aerosol-delivering articles, for example, so-called electronic cigarette devices. These devices typically contain e-juice that is heated to atomize it, producing an inhalable vapor or aerosol. The e-liquid may contain nicotine and/or fragrance and/or aerosol-generating substances (eg, glycerin). Except for the fragrance in e-liquid.

The known electronic cigarette device usually includes a porous ceramic body with a large number of micropores inside for absorbing and conducting the above-mentioned e-liquid, and a heating element is arranged on one surface of the porous ceramic body to heat and atomize the sucked e-liquid. On the one hand, the micropores in the porous body serve as a channel for the e-liquid to infiltrate and flow to the atomizing surface, and on the other hand, they serve as an air exchange channel for supplying air into the oil storage chamber from the outside after the e-liquid is consumed in the oil storage chamber to maintain the air pressure balance in the oil storage chamber. , so that when the e-liquid is heated and atomized, bubbles will be generated in the porous ceramic body, and then the bubbles will emerge from the oil suction surface and enter the oil storage cavity.

For the above known electronic cigarette devices, when the e-liquid in the internal liquid storage chamber is consumed, the liquid storage chamber gradually becomes a negative pressure state, thereby preventing the fluid transfer to a certain extent and reducing the microscopic flow of e-liquid through the porous ceramic body. The orifice channels pass to the atomizing surface for vaporization. In particular, when the known electronic cigarette device is continuously inhaled, it is difficult for the air outside the liquid storage chamber to enter the liquid storage chamber through the microporous channels of the porous ceramic body in a short period of time, thereby slowing down the transfer of e-liquid to the mist. Insufficient e-liquid supplied to the heating element will cause the temperature of the heating element to be too high, which will cause the components of the e-liquid to decompose and volatilize to form harmful substances such as formaldehyde.

Yet another embodiment of the present application also provides an electronic atomization device, comprising an atomizer for atomizing a liquid substrate to generate aerosol, and a power supply mechanism for supplying power to the atomizer; the atomizer includes the above-mentioned atomizer.
