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
One important heating technology direction for existing heated aerosol products is carbon heating. Compared with other heating aerosol products, the carbon heating mode does not need continuous support of a heating appliance in the process of smoking, and the use is light. Carbon heating does not need extra energy supply, ignition of the carbon medium is needed by using an external heat source at the beginning, the existing carbon medium is usually carbon particles, the ignition of the external heat source can only be realized by igniting and heating from the outer surface of the carbon medium, and the ignition mode has great limitation on the arrangement of the carbon particles.
In prior art carbon heated aerosol products, carbon as a heat source is typically in the form of carbon particles that are ignited by an external point disposed at the tip of the aerosol generating medium. The form and location of the carbon particles is primarily to facilitate external ignition and to prevent accidental ignition of the aerosol generating medium during ignition. The end design of the carbon particles easily causes the dropping of the heated carbon particles, and the carbon starts to burn from the outside and has a certain limitation on the heating of the medium. In addition, what is more critical, the carbon particles are usually ignited by an external ignition source, and in some application occasions, the limited ignition source causes the use experience to be reduced and the fire risk to be increased.
The present invention has been made to solve the above problems.

In a first aspect of the invention, a microwave-type carbon heating ignition method is provided, which comprises supplying electric energy to a microwave generator, generating microwave, generating heat in a carbon medium by the microwave, and igniting the carbon medium with the heat.
Preferably, it is achieved by supplying electrical energy to a microwave generator which in turn generates microwaves which cause heat to be generated within the carbon medium and with that heat the carbon medium is ignited, which in turn further heats the aerosol generating medium to generate an aerosol. The microwave generator may be in contact with or not in contact with the carbon medium, as long as the carbon medium can receive the microwaves generated by the microwave generator.
