Description
Technical Field
The invention belongs to the field of aerosol generating products and aerosol generating devices, and particularly relates to a microwave type carbon heating ignition method, an ignition device and a heating system.
Background
An important heating technical direction of the existing heating aerosol products is carbon heating. Compared with other heating aerosol products, the carbon heating mode does not need continuous support of a heating device in the sucking process, and the carbon heating mode is convenient to use. The carbon heating does not need extra energy supply, and the existing carbon medium is usually carbon particles when the carbon medium needs to be ignited by using an external heat source, and the external heat source can only ignite and heat the carbon medium from the outer surface of the carbon medium, so that the ignition mode has great limitation on the layout of the carbon particles.
In existing carbon heated aerosol products, the carbon as a heat source is typically placed in the form of carbon particles at the tip of the aerosol generating medium, which ignites the carbon particles through an external point. The carbon particle form and the set position are mainly used for facilitating the external ignition and preventing the aerosol-generating medium from being ignited by mistake during the ignition process. The carbon particle end design easily causes the heated carbon particles to fall off, and the carbon starts burning from the outside to heat the medium with certain limitation. In addition, it is more critical that the ignition of carbon particles is typically accomplished by an external fire source, which in some applications is limited resulting in a reduced use experience and increased risk of fire.
The present invention has been made to solve the above problems.
