Description

Aerosol generating device and aerosol generating system

This application claims the priority of the Chinese patent application with the application number "202111220257.4" and the application title "Aerosol Generating Device and Aerosol Generating System" submitted to the State Intellectual Property Office of China on October 20, 2021, the entire content of which is passed References are incorporated in this application.

technical field

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

In order to avoid microwave leakage, the casing of the non-combustible appliance is usually made of metal material. The thickness of the casing of the current non-combustible appliance is relatively large, resulting in a large weight of the non-combustible appliance, which brings great inconvenience to users.

application content

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 present application proposes an aerosol generating device, comprising: a housing, the housing is provided with a resonant cavity, and the thickness of the cavity wall of the resonant cavity is greater than the skin depth of the cavity wall of the resonant cavity; The component is arranged in the housing, and the microwave component is used to feed microwaves into the resonant cavity; the resonant column, the first end of the resonant column is connected with the cavity bottom wall of the resonant cavity, and the second end of the resonant column faces the opening of the resonant cavity.

In the aerosol generating device provided by the present application, a resonant cavity is provided in the housing, and a microwave component can be installed on the housing. The microwave component can generate microwaves. The housing is provided with a resonant cavity, and the microwave component can feed microwaves into the resonant cavity. The resonant column is installed in the resonant cavity, and the diameter of the resonant column is smaller than that of the resonant cavity, so there is a gap between the outer wall of the resonant cavity and the inner wall of the resonant cavity, and microwaves can be transmitted within this part of the distance. 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 skin depth refers to the thickness where most of the charges are when the charges propagate in the conductor. The skin depth of the cavity wall of the resonant cavity belongs to the effective thickness of the cavity wall of the resonant cavity to propagate the charge. When the thickness of the cavity wall of the resonant cavity is greater than that of the resonant cavity If the skin depth of the cavity wall is small, it is difficult for the charge to pass through the cavity wall of the resonant cavity. At this time, the thickness of the cavity wall of the resonant cavity meets the conditions for the resonant cavity to conduct microwaves stably, and microwave leakage is not easy to occur, so it does not need too much Increase the thickness of the cavity wall of the resonant cavity. Comparing the thickness of the cavity wall of the resonant cavity with the skin depth of the cavity wall of the resonant cavity, the cavity of the resonant cavity can be reduced as much as possible without leaking microwaves. The thickness of the wall can reduce the amount of metal materials used in the aerosol generating device, effectively reduce the weight of the aerosol generating device, and make it more convenient for users to carry and use the aerosol generating device, which is conducive to improving user experience.

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

The thickness of the metal cavity wall is greater than the skin depth of the metal cavity wall, and the charge It is difficult to pass through the metal cavity wall. At this time, the thickness of the metal cavity wall meets the conditions for the resonant cavity to conduct microwave stably, and microwave leakage is not easy to occur. Therefore, it is not necessary to increase the thickness of the metal cavity wall too much. Comparing the thickness of the metal cavity wall with the skin depth of the metal cavity wall, the thickness of the metal cavity wall can be reduced as much as possible without leaking microwaves, thereby reducing the amount of metal materials used in the aerosol generating device and effectively reducing the aerosol The weight of the generating device makes it more convenient for the user to carry and use the aerosol generating device, which is conducive to improving the user experience.

In this design, the cavity wall that defines the resonant cavity can be made of a part of non-metallic material and a part of metal material. Although metal material can effectively avoid microwave leakage, metal has better thermal conductivity, and the heat in the resonant cavity will Through the rapid dissipation of metal materials, in order to avoid the above situation, the cavity wall defining the resonant cavity in this design includes a first non-metallic part and a first conductive coating, the first conductive coating can prevent microwave leakage, and the first non-metallic The thermal conductivity of the component is poor, so that the heat of the resonant cavity can be prevented from being quickly lost, and the heat preservation effect is better, which is beneficial to improving the energy utilization rate. In addition, if only metal materials are used as the cavity wall of the resonant cavity, in order to avoid heat loss, it is necessary to increase the thickness of the cavity wall of the resonant cavity. Increasing the thickness of the cavity wall of the resonant cavity can not only reduce the amount of metal materials used, but also reduce the weight of the aerosol generating device, and improve the convenience of carrying and using the aerosol generating device for users.

The thickness of the first conductive coating is greater than the skin depth of the first conductive coating, and it is difficult for charges to pass through the first conductive coating. At this time, the thickness of the first conductive coating satisfies the conditions for the resonant cavity to conduct microwaves stably, and microwaves are not easy to occur. Leakage occurs, so there is no need to increase the thickness of the first conductive coating too much. Comparing the thickness of the first conductive coating with the skin depth of the first conductive coating can ensure that microwaves do not leak Next, reduce the thickness of the first conductive coating as much as possible, thereby reducing the amount of metal materials used in the aerosol generating device, effectively reducing the weight of the aerosol generating device, and making it more convenient for users to carry and use the aerosol generating device. It is beneficial to improve the user experience.

In addition, compared with the way of processing metal materials, it is more convenient to use non-metallic materials to process the cavity wall of the resonant cavity, which can effectively reduce the processing difficulty of the aerosol generating device. After processing the first non-metallic part, it can be used The first conductive coating is formed on the first non-metallic part by spraying.

In this design, the first conductive coating is located in the first non-metallic part, that is, the second non-metallic part is sleeved on the first conductive coating. When the aerosol generating device is working, microwaves are blocked by the first conductive coating. , making it difficult for microwaves to contact the first non-metallic part, and avoiding energy waste caused by microwaves acting on the first non-metallic part.

Exemplarily, if the first non-metallic part is located inside the second conductive coating, microwaves will directly act on the first non-metallic part, resulting in waste of energy.

In a possible design, the resonance column includes: a metal resonance column, the minimum distance L from the center line of the metal resonance column to the sidewall of the metal resonance column is greater than the skin depth of the metal resonance column.

In this design, the entire resonant column is made of metal material. The minimum distance L from the center line of the metal resonance column to the side wall of the metal resonance column is greater than the skin depth of the metal resonance column. At this time, the radial dimension of the resonance column meets the conditions for the resonant cavity to conduct microwaves stably. The resonance column is used as a cylinder for illustration. Through the above structural limitations, it is not necessary to increase the radial dimension of the resonant column too much. Comparing the radial dimension of the resonant column with the skin depth of the resonant column can reduce the radial dimension of the resonant column as much as possible, thereby enabling The amount of metal materials used in the aerosol generating device is reduced, the weight of the aerosol generating device is further reduced, and the user is more convenient to carry and use the aerosol generating device, which is conducive to improving the user experience.

In order to ensure that the microwave can be stably transmitted between the resonant column and the cavity wall of the resonant cavity, it is necessary to ensure that the cavity of the resonant column and the resonant cavity The distance between the walls meets certain conditions, so it is necessary to increase or decrease the radial dimension of the resonant column according to the size of the resonant cavity. By arranging the first non-metallic part as a part of the resonant column in the design, not only the amount of metal materials used can be reduced, but also the weight of the aerosol generating device can be reduced, and the convenience for users to carry and use the aerosol generating device can be improved.

In addition, compared to the method of processing metal materials, it is more convenient to use non-metallic materials to process the resonant column, which can effectively reduce the difficulty of processing the aerosol generating device.

The aerosol generating component can be accommodated in the mounting seat, so as to realize the fixation of the aerosol generating component, without plugging the aerosol generating component and the resonant column, avoiding the contact between the resonant column and the aerosol generating component, thereby avoiding the resonant column Dirt occurs, reducing the cleaning workload of the resonant column.

In a possible design, the mount is detachably connected to the body.

In this design, the connection mode between the mounting base and the body is limited. The mounting base can be disassembled from the housing. The main body, thereby opening the opening of the resonant cavity, can facilitate the cleaning of the resonant cavity and the mounting seat separately, improve the convenience of cleaning the aerosol generating device, and further improve the user's convenience of using the aerosol generating device.
