Description

Technical Field

[0001] The utility model relates to the technical field of electronic atomization, in particular to an atomization core and an atomizer and an electronic cigarette using the same. Background Art

[0002] At present, when assembling the atomizer core of the existing electronic cigarette, the heating elements of the oil-absorbing and heating components are all in the shape of wire windings, and the main body is relatively soft. After being wrapped in the oil-absorbing component, the supporting force on the inside of the oil-absorbing component is small, and the heating elements are all wrapped in the middle position inside the oil-absorbing component, resulting in the upper and lower ends of the oil-absorbing component being not supported by the heating elements and being relatively loose. During the installation of the oil-absorbing and heating component into the atomization cavity of the atomization core, the oil-absorbing component is squeezed by fingers or the cavity wall of the atomization cavity, which will cause the ventilation channels of the heating element and the oil-absorbing component to deform. When the atomization core is assembled into the atomizer and powered on for use, it will cause the heating element to short-circuit and the ventilation channel to be blocked. In addition, after the oil-absorbing component is saturated with oil in the oil storage cavity of the atomizer, since the two ends of the oil-absorbing component are relatively loose, the oil will gather to the two ends of the oil-absorbing component under the action of gravity, resulting in oil dripping.
