Description

Aerosol-generating substrates, aerosol-generating devices and systems

technical field

The present application belongs to the technical field of electronic atomization, and in particular relates to an aerosol generating substrate, an aerosol generating device and a system.

Background technique

A heat not burn (Heat Not Burning, HNB) device is an electronic device that heats without burning the aerosol-generating substrate (treated plant leaf products). The heating device heats the aerosol-generating substrate to a temperature at which the aerosol-generating substrate can generate the aerosol but is not high enough to burn through high temperature, so that the aerosol-generating substrate can generate the aerosol required by the user under the premise of not burning.

Heat-not-burn appliances currently on the market mainly adopt resistance heating, that is, use a central heating sheet or a heating needle to insert from the center of the aerosol-generating substrate into the interior of the aerosol-generating substrate for heating. This kind of appliance needs to be preheated for a long time before use, and it cannot be pumped and stopped freely. The carbonization of the aerosol-generating matrix is uneven, resulting in insufficient baking of the aerosol-generating matrix and low utilization rate; Dirt is generated in the matrix extractor and the base of the heating sheet, which is difficult to clean; the local aerosol in contact with the heating element will cause the temperature of the matrix to be too high, and partial cracking will occur, releasing substances harmful to the human body. Therefore, microwave heating technology has gradually replaced resistance heating as a new heating method. Microwave heating technology has the characteristics of high efficiency, timeliness, selectivity and no delay in heating, and it only has a heating effect on substances with specific dielectric properties. The application advantages of using microwave heating atomization are: a. Microwave heating is radiation heating, non-thermal conduction, which can realize immediate pumping and stop; b. There is no heating sheet, so there is no problem of broken pieces and cleaning heating sheets; c. Aerosol generation The matrix utilization rate is high, the taste consistency is high, and the taste is closer to cigarettes.

However, the position close to the microwave emission end in the aerosol generation matrix can be uniformly heated, and the heating effect is poor in the position far from the microwave emission end in the aerosol generation matrix, resulting in a low utilization rate of the aerosol generation matrix.

Contents of the invention

This application aims to solve one of the technical problems existing in the prior art or related art.

In view of this, in the first aspect, the application proposes an aerosol generating substrate, including: an aerosol substrate part, an aerosol substrate is arranged in the aerosol substrate part, an insertion part is provided in the aerosol substrate part, and the insertion part It is used for inserting the resonant column of the aerosol generating device, and is arranged at intervals with the resonant column.

The aerosol matrix part is provided with an aerosol matrix, and when the microwave acts on the aerosol matrix, the aerosol matrix is heated under the action of the microwave, so that the aerosol matrix can generate aerosol. The aerosol matrix part is provided with a plug-in part, and the resonant column can be inserted into the plug-in part. The distance between the resonant column and the two ends of the aerosol matrix part is small, and the part with a large distance from the resonant column is not easy to appear on the aerosol matrix part. That is, the aerosol matrix at various locations in the aerosol matrix part can be uniformly heated by the microwaves conducted by the resonant column, which is beneficial to improving the utilization rate of the aerosol matrix.

The resonant column and the aerosol matrix are arranged at intervals to avoid contact between the resonant column and the aerosol matrix, thereby preventing the resonant column from being dirty and reducing the cleaning workload of the resonant column.

In addition, according to the aerosol generating substrate in the above technical solution provided by the present application, it can also have the following additional technical features:

In a possible design, the aerosol matrix part further includes: a partition part, the aerosol matrix is located in the partition part, and the partition part is used to separate the aerosol matrix and the resonance column.

In this design, the aerosol matrix part includes an aerosol matrix and a partition, wherein the aerosol matrix is located in the partition, and the partition wraps the aerosol matrix to avoid contact between the aerosol matrix and the resonant column, thereby preventing the aerosol matrix from contacting the resonant column. Resonant column contacts. Moreover, when the aerosol matrix is heated, the temperature is high, and the separation of the aerosol matrix and the resonant column can also prevent the aerosol matrix from sticking to the resonant column, and reduce the cleaning workload of the resonant column.

Of course, in order to avoid sticking between the partition and the resonant column, it is necessary to set the partition to a material that is not easy to interact with microwaves, and it is necessary to set the partition to have a supporting effect, so the partition can be made of high-permeability hard paper or white kraft paper , polytetrafluoroethylene film, porous ceramic sheet, synthetic resin, chemical fiber products, polylactic acid film, aluminum foil paper, and non-woven fabric.

The resonant column can be used as a conductor, and the resonant column can be made of metal material, for example, the resonant column is made of copper, aluminum, iron, etc. or alloys thereof. The resonant column is used to transmit microwaves and increase the microwave transmission rate. When microwaves are transmitted in the resonant cavity, it is not easy to attenuate, and the effect of microwaves acting on the aerosol-generating matrix is improved, so that microwaves can efficiently and quickly act on the aerosol-generating matrix, which is beneficial Meet the needs of users. The aerosol generating substrate includes an aerosol substrate part, and an aerosol substrate is arranged in the aerosol substrate part. When the microwave acts on the aerosol substrate, the aerosol substrate is heated under the action of the microwave, so that the aerosol substrate can generate aerosol. The aerosol matrix part is provided with a plug-in part, and the resonant column can be inserted into the plug-in part.
