Description

This application relates to the technical field of electronic atomization, and more specifically to an atomization module and an aerosol generating device.

A heat not burning (HNB) device is an electronic device that heats an aerosol-generating substrate (a treated plant leaf product) without burning it. The heating device heats the aerosol-generating substrate to a high temperature that can generate aerosols but does not result in combustion, allowing the aerosol-generating substrate to generate the aerosol desired by the user, without burning the substrate.

Currently, non-combustion heating devices on the market mainly adopt the resistance heating method. That is, the aerosol generating substrate is heated by inserting a central heating tip or a heating needle into the substrate from the center. Such devices require preheating before use, so the waiting time is long and inhalation and stopping cannot be performed freely. In addition, the aerosol generating substrate is unevenly carbonized and the baking of the aerosol generating substrate is insufficient, so the utilization rate is low. In addition, the heating tip of the HNB device is prone to causing dirt on the aerosol generating substrate removal device and the heating tip base, making cleaning difficult. In addition, the temperature of the aerosol generating substrate in the part in contact with the heating element rises too high, causing partial decomposition, which releases substances harmful to the human body. Therefore, microwave heating technology is gradually replacing the resistance heating method as a new heating method. Microwave heating technology has the characteristics of being efficient, rapid, selective and without delay in heating, and has a heating effect only on materials with specific dielectric properties. The application advantages of adopting microwave heating atomization include the following:

a. Microwave heating is radiation heating, not thermal conduction, so instant inhalation and instant stopping are possible.

b. Since it does not have a heat generating tip, there are no problems with chip breakage or cleaning the heat generating tip.

c. The utilization rate of the aerosol-generating substrate is high, and the consistency of the draw is high, resulting in a draw that is more similar to that of a cigarette.

However, in typical atomization by microwave heating, a conductor column through which microwaves are introduced is inserted into the aerosol-generating substrate. As a result, after inhalation, the aerosol-generating substrate is prone to have soot generated by combustion due to high-temperature heating that adheres to the conductor rod installed in the aerosol generating device, and cleaning is difficult.

The purpose of this application is to solve at least one of the technical problems existing in the prior art.

Therefore, in a first aspect, the present application provides an atomization module.

In a second aspect, the present application provides an aerosol generating device.

In a first aspect, the present application provides an atomization module. The atomization module includes a first housing having a first gas path extending therethrough, a second housing configured to form a cavity structure with one open end, covering at least a part of the exterior of the first housing through the opening and connected to the first housing, forming a second gas path between the first housing and the second gas path, and an aerosol generating module installed in the second housing and capable of generating an aerosol.

Therefore, the present application provides an atomization module including a first housing, a second housing, and an aerosol generation module. A first gas path is provided through the inside of the first housing. The second housing has a cavity structure with one end open. The second housing is provided to cover at least a part of the outside of the first housing through the opening and is connected to the first housing. A second gas path is formed between the first housing and the second housing. The second gas path is also connected to the first gas path. In this way, an intake gas path is formed that is connected to the inside of the atomization module, ensuring air flow inside the atomization module during inhalation.

Furthermore, the second housing has a cavity structure with one end open, and the aerosol generating module is installed in the second housing. By covering the first housing with the second housing, the aerosol generating module is placed in a highly sealed environment. This further ensures that the aerosol generating module receives heat uniformly, improving the utilization rate of the aerosol generating module. In addition, the atomization module provided in the present application does not require components such as a conductor rod, a heating tip, or a heating needle. This avoids the problem that these components are inserted into the atomization module, causing soot to stick between the aerosol generating module and the atomization module, making cleaning difficult. Furthermore, since the bottom of the atomization module is installed in a sealed state, the aerosol generating device in which the atomization module is installed will not be contaminated after the atomization module is installed in the aerosol generating device.

Specifically, the first housing and the aerosol generation module are in close contact with each other. This ensures the stability of the internal structure of the atomization module, ensures that air flows within the first gas path during inhalation, and prevents air from escaping from inside the atomization module.

Specifically, the first and second housings are connected by an engagement groove to prevent the second housing from falling off.

Specifically, the first housing is one of a paperboard tube having a supporting function, a polylactic acid material tube, a polytetrafluoroethylene tube, a synthetic resin tube, a protein material tube, a vegetable rubber-based material tube, or a cellulose derivative material tube.

Specifically, the first and second housings are made of a low dielectric loss material that has a certain strength and can be fixed in shape. The first and second housings can be manufactured from one of a paperboard tube, a polylactic acid material, polytetrafluoroethylene, a synthetic resin, a chemical fiber product, a nonwoven fabric, a ceramic plate, a PEEK material, and glass.

Specifically, the length of the atomization module is 30 to 70 mm, and preferably 40 to 50 mm.

In this way, the atomization module provided by the present application has a connected inhalation gas path formed therein, so that the flow of air inside the atomization module during inhalation is guaranteed. In addition, the second housing has a cavity structure with one end open so that the inside of the atomization module is a tightly sealed environment. This ensures that the aerosol generating module receives heat uniformly, improving the utilization rate of the aerosol generating module. In addition, the atomization module provided by the present application does not require components such as a conductor rod, a heating tip, or a heating needle. This avoids the problem that these components are inserted into the atomization module and stick to the aerosol generating module, making cleaning difficult. In addition, since the bottom of the atomization module is installed in a sealed state, the aerosol generating device in which the atomization module is installed will not be contaminated after the atomization module is installed in the aerosol generating device.

Furthermore, in this technical solution, the heating element is installed in the first through-hole of the aerosol-generating substrate. In this way, when the aerosol-generating substrate is heated using microwaves, even the aerosol-generating substrate located at the peripheral portion can be located in a strong microwave field. This ensures that the aerosol-generating substrate at the peripheral portion receives sufficient heat, ensuring that the heat received by the entire aerosol-generating substrate is uniform, thereby enhancing the atomization effect of the aerosol in the aerosol-generating substrate and improving the utilization rate of the aerosol-generating substrate.

Specifically, the heating element is a microwave absorbing material with relatively excellent resistance to high temperatures, and has the characteristics of good impedance matching, wide bandwidth, thin matching thickness, light weight, and strong absorption capacity, which can enhance the atomization effect of the aerosol in the aerosol-generating substrate.

Specifically, the manufacturing material for the heating element may be one of ferrite, ceramic-based material, silicon carbide, barium titanate, and magnetic metal powder.

In any of the above technical solutions, there is a preset distance between one end of the aerosol-generating substrate close to the opening and the opening end of the second housing.

In this technical solution, there is a preset distance between the end of the aerosol-generating substrate and the open end of the second housing, so the length of the second body section is guaranteed. During inhalation, air enters the second gas path from the air inlet at the open end of the second housing, travels a preset distance, passes through the aerosol-generating substrate, and flows into the first gas path accompanied by aerosol. It is also possible to prevent aerosol from leaking from the air inlet.

This is beneficial for protecting the market order and the legitimate rights and interests of consumers.

Specifically, the identification device feeds back an identification signal to the RF transmitting device in the microwave module. When the RF transmitting device receives the identification signal, it performs verification and matching. If the identification signal is successfully verified, the microwave module activates the heating function for the atomization module, but if the identification signal is not successfully verified, the microwave module does not activate the heating function for the atomization module.

The aerosol-generating substrate 114 is covered by the positioning member 120 through the first through-hole 116. The free end of the positioning member 120 abuts against the heating member 118. In this way, a step structure is formed between the first body section 110, the second body section 112, and the positioning member 120, and the aerosol-generating substrate 114 is covered by the positioning member 120, thereby realizing orderly and tightly connection between the second body section 112, the positioning member 120, and the aerosol-generating substrate 114.

Furthermore, in this embodiment, as shown in Figs. 2 and 3, the first gas path 104 penetrates the first body section 110, the second body section 112, the positioning member 120, and the heating member 118. During inhalation, air enters the second gas path 126 from the air inlet 124, passes through the path between the multiple protrusions 128, and then directly enters the first gas path 104, ensuring smooth air flow.

The seventh embodiment of the present application provides a nebulization module. Based on the fourth embodiment, the heating member 118 further includes a plurality of second through holes 122, as shown in FIG. 6. The plurality of second through holes 122 are connected to the first gas path 104.

In this embodiment, as shown in FIG. 6, a plurality of second through holes 122 are provided in the heating member 118. Furthermore, the second through holes 122 are connected to the first gas path 104. In this way, during inhalation, the aerosol generated by the aerosol-generating substrate 114 can directly enter the first gas path 104 through the second through holes 122, thereby enhancing the atomization effect of the aerosol in the aerosol-generating substrate 114.

In addition, the atomization module provided in this embodiment has all the beneficial effects of the atomization module in the fourth embodiment, but we will not discuss them one by one here.

The eighth embodiment of the present application provides an atomization module. Based on the fourth embodiment, the atomization module further includes an identification device (not shown).

In this embodiment, the identification device is installed inside the heating member 118. The identification device can feed back the identification signal sensed by the RF transmitting device. This can strengthen the consistency when the atomization module and the microwave module identify each other, and provide an anti-counterfeiting function, making cracking and recycling difficult. This is beneficial for protecting the market order and the legitimate rights and interests of consumers.

In a specific embodiment, the identification device transmits an identification signal to an RF transmitting device in the microwave module. When the RF transmitting device receives the identification signal, it performs verification and matching. If the identification signal is successfully verified, the microwave module activates a heating function for the atomization module, but if the identification signal is unsuccessful, the microwave module does not activate a heating function for the atomization module. This enhances the consistency when the atomization module and the microwave module identify each other, thereby achieving the purpose of automatically identifying counterfeit atomization modules. In a specific embodiment, the outside of the identification device is covered with a high-temperature resistant insulating material to provide protection for the identification device. The insulating material is one of insulating cotton, polyurethane foam, and polyamide.

In addition, the atomization module provided in this embodiment has all the beneficial effects of the atomization module in the fourth embodiment, but we will not discuss them one by one here.

A ninth embodiment of the present application provides an aerosol generating device including an atomization module, a microwave module, an RF transmitting device, and a power storage device according to any of the above embodiments.

The aerosol generating device provided in the present application includes an atomization module according to any of the above embodiments. Therefore, it has all the beneficial effects of the atomization module described above, but these will not be discussed in detail here.

Furthermore, in this embodiment, the aerosol generating device further includes a microwave module, an RF transmitting device, and a power storage device. The microwave module is used to introduce microwaves into the atomization module to heat the aerosol generating substrate 114 and generate aerosol. The power storage device is electrically connected to the microwave module and the RF transmitting device and is used to supply electricity to the microwave module and the RF transmitting device. The RF transmitting device can receive an identification signal fed back from the identification device, and verifies and matches the atomization module to achieve an anti-counterfeiting effect.

In a specific embodiment, the RF transmitting device receives the identification signal fed back from the identification device and performs verification and matching. If the identification signal is successfully verified, the microwave module supplies microwaves to the atomization module to heat the aerosol-generating substrate 114, but if the identification signal is unsuccessful, the microwave module does not supply microwaves to the atomization module. This enhances the consistency when the atomization module and the microwave module identify each other, thereby achieving the purpose of automatically identifying counterfeit atomization modules. This is beneficial to protecting market order and the legitimate rights and interests of consumers.

In a specific embodiment, the frequency band for microwave heating is 300 MHz to 300 GHz, preferably 915 MHz and 2450 MHz.

In a specific embodiment, the nebulization module is disposable and removably installed in the aerosol generating device. Therefore, it is discarded after inhalation, does not require cleaning, and is easy to replace, ensuring simplicity of use.

Therefore, the aerosol generating device provided in the present application can achieve uniform heating of the aerosol generating substrate 114. In addition, since it can automatically identify counterfeit atomization modules, it is advantageous for protecting market order and the legitimate rights and interests of consumers.
