Atomization core, atomizer and aerosol generating device

Abstract

The invention relates to the technical field of aerosol generating devices, and specifically discloses an atomization core. The atomization core comprises a first shell, a first end part and a secondend part are arranged at opposite positions of the first shell, a first connecting port is formed in the first end part, an internal thread is arranged on the first connecting port, a first boss is arranged at the second end part, and first O-shaped sealing rings are arranged at the top end of the first end part and the first boss. The invention further discloses an atomizer. The atomizer comprises a second shell and an atomization support. A third end part and a fourth end part are arranged at opposite positions outside the atomization support, and a fourth connecting port and a fifth connecting port are formed in the corresponding positions in the atomization support. The connecting parts between the atomization core and the atomization support are hermetically connected in a manner of arranging a sealing ring in a threaded manner, and the connecting parts between the atomization support and the atomizer shell are hermetically connected in a manner of arranging the sealing rings in athreaded manner, so that connecting gaps among atomizer parts are filled, the leakage of non-atomized tobacco juice is reduced, and the user experience is improved.

Description

technical field [0001] The invention belongs to the technical field of aerosol generating devices, and in particular relates to an atomizing core, an atomizer and an aerosol generating device. Background technique [0002] The atomizer of the aerosol generating device is mainly composed of an atomizing core, an atomizing bracket, and a shell. At present, there are many kinds of atomizers, which are mainly divided into integrated and detachable atomizers, and detachable atomizers. Detachable, washable and replaceable, more hygienic. [0003] However, since there is a gap between the components of the detachable atomizer, the atomizer bracket and the atomizer core during assembly, the e-liquid is easy to leak out from the gap. If the leaked e-liquid is unatomized When using e-liquid, it will cause the user to inhale the un-atomized e-liquid, resulting in a bad user experience of inhaling the un-atomized e-liquid. Contents of the invention [0004] The purpose of the presen...
