Abstract

The application relates to the technical field of atomizing equipment, in particular to a sealing plug of an atomizing device and the atomizing device. The sealing plug of the atomization device comprises a supporting core body, a blocking layer and an elastic sealing layer, wherein the blocking layer is coated outside the supporting core body and used for blocking permeation of aroma components, the elastic sealing layer is coated outside the blocking layer and used for being attached to and sealed with the inner wall of a corresponding channel in the atomization device so as to block the channel, and the blocking effect of the blocking layer on permeation of the aroma components is larger than that of the elastic sealing layer. Due to the adoption of the multi-layer composite structure comprising the supporting core body, the blocking layer and the elastic sealing layer, the blocking layer can block the permeation of aroma components, so that the loss of the aroma components is reduced, and the sealing effect of the sealing plug is improved.

Description

Sealing plug of atomizing device and atomizing device Technical Field The application relates to the technical field of atomizing equipment, in particular to a sealing plug of an atomizing device and the atomizing device. Background Aerosol substrates for generating aerosols are generally provided in atomizing devices, and some aerosol substrates contain aroma components composed of essence and perfume, which are easily attenuated by volatilization, oxidation, and the like. Therefore, when the atomization device is stored, both ends of a suction nozzle, an air inlet and other channels of the atomization device are sealed by the silica gel plug so as to reduce the emission of aroma components, but a part of the aroma components permeate and are emitted outside the atomization device, so that the sealing effect is poor. Disclosure of utility model The application provides a sealing plug of an atomization device and the atomization device, in order to improve the sealing effect of the sealing plug and reduce the loss of aroma components. According to a first aspect, in one embodiment there is provided a sealing plug for an atomising device comprising: supporting the core; The barrier layer is coated outside the supporting core body and is used for blocking permeation of aroma components; the elastic sealing layer is coated outside the blocking layer and is used for being attached and sealed with the inner wall of a corresponding channel in the atomizing device so as to block the channel; The barrier layer has a greater barrier effect to permeation of aroma components than the elastic sealing layer. In one embodiment, the material of the barrier layer is one or more of polyamide, ethylene vinyl alcohol copolymer, polyvinylidene chloride and polyester. In one embodiment, the thickness of the barrier layer is not less than 2 μm. In one embodiment, the barrier layer has a thickness of 2 μm to 5 μm.
