Description

Atomizing core, atomizer and aerosol generating device

Technical Field

The embodiment of the invention relates to the field of smoking sets, in particular to an atomizing core, an atomizer comprising the atomizing core and an aerosol generating device comprising the atomizer.

Background

A device for converting an atomized liquid containing nicotine or the like into an aerosol by means of heating and atomizing an atomizing core is an electronic product simulating a cigarette, and has a similar smoke, taste and sensation to a cigarette. The aerosol containing nicotine produced by atomization does not contain harmful carcinogenic substances such as tar and the like commonly existing in the smoke of common cigarettes, and is considered to be a cigarette substitute which is beneficial to the health of traditional smokers. Meanwhile, the electronic device has the characteristics of good portability, no naked flame, no second-hand smoke and environmental protection, and is popular with many smokers.

The heating atomization technology of aerosol generating device, there are two main types that are widely used at present: 1) cotton or fiber bundles are used as an oil guide body, and the electric heating wire is wound on the oil guide body to directly heat the tobacco tar for atomization; 2) the honeycomb ceramics is used as an oil guide body, and the tobacco tar is atomized by heating in modes of an electric heating wire or an electric heating belt and the like.

The oil locking capacity of cotton or fiber bundles is limited, and the leaked tobacco tar is often visible at an air inlet and a smoke outlet of an unused new electronic cigarette after the electronic cigarette is placed for a period of time; the 'ceramic atomizing core' with honeycomb ceramics as oil guide body, the essence of the technology that industry adopted is to cover the heating wire or heating belt with thick film printing heating belt on honeycomb ceramics one side surface or unilateral, play oil absorption, lock oil and atomizing effect simultaneously as single components and parts, its manufacturing process is comparatively complicated, this atomizing core should satisfy oil absorption and lead oil rate, needs sufficient aperture and porosity, and the result locks the oil ability not enough.

In addition, in the structure of the existing atomizer, the atomizing surface of the atomizing core is usually directly communicated with the air inlet, that is, a straight-through air passage is mostly adopted, and cotton or honeycomb ceramics full of tobacco tar is used as an isolating body to isolate atomized liquid and aerosol. This kind of structure is favorable to improving atomization efficiency, but to cotton or honeycomb ceramics's oil absorption, lock oily ability requirement extremely high, in order to satisfy the oil absorption ability, is limited to material and process design, and current atomizer ubiquitous oil leak's problem, and the atomizing liquid of seepage (promptly tobacco tar) leaks from the air inlet under the action of gravity, pollutes the sensor and causes failure, pollutes power electrode etc. influences user's use experience. In addition, the atomization efficiency, the smoke yield and the like have larger space for improving.

In order to solve the problems of oil leakage and low atomization efficiency and smoke yield in the prior art, the invention provides an atomization core, an atomizer comprising the atomization core and an aerosol generating device comprising the atomizer.

In a first aspect, the present invention provides an atomising core comprising:

an atomizing wick body having a porous structure for conducting and at least partially storing an atomized liquid, the atomizing wick body having a first surface, a second surface opposite the first surface, and a liquid-wicking surface distinct from the first and second surfaces for at least partially contacting the atomized liquid;

and a heating element provided on the second surface side of the atomizing core main body and configured to heat the atomized liquid conducted through the atomizing core main body to generate aerosol.

Further, the atomizing core also comprises an aerosol escape layer arranged on the second surface side of the atomizing core main body, and the aerosol escape layer is arranged to allow the aerosol to pass through the aerosol escape layer and at least partially prevent the atomized liquid from the atomizing core main body from passing through the aerosol escape layer.

Or, further include aerosol escaping layer, set up to be less than the speed conduction of atomizing core main part the atomized liquid, the heat-generating body set up in aerosol escaping layer keeps away from one side of atomizing core main part.

Further, the heating element is arranged between the aerosol escape layer and the second surface of the atomizing core main body.

Further, the heat generating body is substantially two-dimensional in shape.

Further, the aerosol escape layer and/or the air-intake oil-locking layer are in a porous structure, and the average pore diameter of the aerosol escape layer and/or the air-intake oil-locking layer is smaller than that of the atomizing core main body.

Further, the aerosol escape layer and/or the air-intake oil-locking layer are of a porous structure, and the porosity of the aerosol escape layer and/or the air-intake oil-locking layer is smaller than that of the atomizing core main body.

Further, at least one of the aerosol escape layer, the air inlet oil locking layer and the atomizing core main body is made of ceramic materials.

Further, the air inlet oil locking layer, the atomizing core main body, the heating body and the aerosol escape layer are separated, and the atomizing core is formed by overlapping.

Further, at least two of the air inlet oil locking layer, the atomizing core main body, the heating body and the aerosol escape layer are fixed to form the atomizing core integrally, and the fixation is achieved through bonding or sintering.

Further, the heating body is of a porous structure and comprises a conductive network in electric communication.

Further, the heat generating body includes a metal heating sheet having an opening.

Further, the metal heating plate comprises a nichrome or iron-chromium-aluminum alloy heating plate.

Further, the cross section of the atomizing core main body, the air inlet oil locking layer and/or the aerosol escape layer comprises a rectangle, a rounded rectangle, a square, a rounded square or a circle, and the metal heating plate is in a shape corresponding to the contact surface of the metal heating plate.

Furthermore, the heating element comprises a conductive track printed on the second surface of the atomizing core main body or the surface of the aerosol escape layer by adopting conductive paste in a thick film printing mode.

Further, the atomizing core main part is provided with a blind hole or a through hole with an opening on the liquid suction surface so as to guide the atomized liquid to enter the atomizing core main part, and the transmission distance of the atomized liquid is reduced.

According to the invention, the air inlet oil locking layer and the heating element are respectively arranged on two sides of the atomizing core main body, the side of the heating element is arranged to face the air outlet, and the air inlet oil locking layer is contacted with air, so that the effect of reducing the oil leakage probability can be realized. The reason is that: the air inlet oil locking layer allows air to pass through, and prevents the atomized liquid conducted by the atomizing core main body from passing through the air inlet oil locking layer to a certain extent, so that the probability of leakage of the atomized liquid is reduced, meanwhile, the heating body is positioned at the other side, because sufficient atomized liquid needs to be conducted, and a large amount of generated smoke is continuously and smoothly sucked away, a relatively more open outlet is needed at the side of the heating body, under the condition, the leakage of the atomized liquid is difficult to guarantee, and the invention sets the side of the heating body to face the air outlet, so that the direction of the gravity borne by the atomized liquid faces to the inside of the atomizing core main body under the normal state, and the atomized liquid tends to remain in the atomizing core main body under the action of gravity, so that the probability of oil leakage is reduced.

For the intake airlock oil layer, optionally, the intake airlock oil layer is a porous structure, for example, a ceramic porous structure or an organic porous structure. In order to be able to function as an oil lock, one consideration is to make the porosity and/or average pore diameter of the intake oil-lock layer smaller than that of the atomizing core body; another consideration is to provide a layer of intake lock oil with higher oleophobic properties than the atomizing core body, for example by preparing the intake lock oil layer from a teflon material, or by depositing an oil-phobic layer on the surface of the intake lock oil layer, for example, thereby reducing the probability or rate of passage of the atomizing fluid.

The aerosol-evolving layer provides further oil-locking capability, preferably the aerosol-evolving layer has, for example, a ceramic porous structure or an organic porous structure. The porosity and/or average pore diameter of the porous structure are smaller than those of the atomizing core main body, so that more optimized oil locking capacity is generated, the transmission rate of the atomizing liquid is reduced, and the probability of oil leakage from the atomizing side is further reduced. It will be appreciated that approaching the porosity and/or average pore size of the atomizing core body results in an increased oil entrainment rate and, hence, an increased aerosol generation, but a corresponding decrease in oil lock performance and an increased probability of oil leakage, whereas a smaller porosity and/or average pore size relative to the porosity and/or average pore size of the atomizing core body results in a more optimal oil lock performance, but a corresponding decrease in oil entrainment rate and a decrease in aerosol generation and a reduction in mouth feel. Those skilled in the art can make adjustments and achieve optimum performance in light of the present disclosure. Alternatively, it is preferable that the layer of the gas-lock oil has a porosity of 40 to 50%, an average pore diameter of 20 to 30 μm, and a thickness of 0.5 to 1.5 mm; preferably, the atomizing core body has a porosity of 60-90%, an average pore size of 40-100 μm, and a thickness of 2-4 mm; preferably, the aerosol-evolving layer has a porosity of 70-80%, an average pore diameter of 20-70 μm and a thickness of 0.3-1 mm. Further, in order to satisfy the rapid escape condition of the atomized aerosol generated via the heat generating sheet, the thickness of the aerosol escape layer is preferably controlled to be 0.5mm or less.

The atomizing core body can be a uniform porous structure with conventional optional porosity and/or average pore size to meet the requirement of sufficient oil guiding rate; the atomizing core main part also can have a through hole or a blind hole with an opening on the oil absorption surface, and the open hole or the blind hole can further reduce the transmission distance from the atomized liquid to the heating body, so that the transmission efficiency of the atomized liquid is further improved.

The air inlet oil locking layer, the atomizing core main body, the heating body and optionally the aerosol escape layer can be combined in a laminated mode to form the atomizing core, and can also be at least partially fixed to form the atomizing core integrally, and the fixation can be bonding or sintering. It will be appreciated that the combination of the layers to form the atomizing core is advantageous for batch processing of the individual parts, reducing costs, and that the individual parts can be individually produced in batch automation, cut automatically, and assembled at a later time. It will be appreciated that the at least partial fixing to form the atomising core integrally has a more complex process but facilitates later assembly, reducing assembly difficulties.

The sintering may be, for example, directly combining the gas inlet and oil lock layer, the atomizing core body, the heating element, and optionally the aerosol escape layer by blank molding, and then the whole is fired through degumming and pore forming processes.

The optional heat generating body is substantially in the shape of a two-dimensional shape which can be easily fixed to a surface of the porous body, such as the surface of the atomizing wick body or the aerosol-evolving layer, said surface of the porous body preferably being substantially flat.

The heat generating body is preferably a metal heat generating sheet, and is preferably made of an electrochromic sheet material of, for example, nichrome or iron-chromium-aluminum alloy. It can be understood that the smaller the thickness of the metal heat generating sheet, the larger the resistance value thereof, and conversely, the larger the thickness of the metal heat generating sheet, the smaller the resistance value thereof. The metal heat generating sheet is generally formed with an opening pattern thereon to adjust the resistance, and it can be understood that the larger the opening area percentage is, the larger the resistance value is, and conversely, the smaller the opening area percentage is, the smaller the resistance value is. Alternatively, the thickness of the metal heating sheet is preferably 30-80 μm, and the percentage of open area is preferably 50-70%. The openings have 2 purposes: 1) the conductive area (volume) of the heating sheet is reduced, and the macro resistance is improved; preferably, the overall resistance value of the heating sheet is controlled within the range of 1-2 omega; 2) the tobacco tar can absorb heat through the heating sheet and is converted into steam to escape.

The metal heating sheet is adapted to the shape of the atomizing core main body and/or the aerosol escape layer and can be rectangular, round-cornered rectangular, square, round-cornered square or circular, for example. The shape of the holes on the metal heating sheet for allowing the smoke oil and steam to pass through is suitable for ensuring uniform heating, and is suitable for square shapes, as shown in fig. 7-9.

The strength of the metal sheet with the thickness of 30-80 μm is not enough to support the direct covering on the surface of the honeycomb ceramics, and the metal sheet is easy to deform and even break especially under the condition of opening large-area holes. Therefore, the ultrathin porous alloy heating sheet is preferably clamped between the atomizing core main body and the aerosol escape layer, on one hand, the structural integrity of the ultrathin heating sheet can be ensured, and on the other hand, the heat diffusion can be limited by utilizing the heat insulation characteristic of the honeycomb ceramic, so that the energy utilization rate of a power supply is improved, and the efficiency of transferring heat to atomized liquid is improved.

The heating element can also be a coating heating element, for example, a porous ultrathin alloy heating sheet is directly covered on the aerosol escaping layer by adopting technical approaches such as vacuum sputtering, vacuum coating and the like, so that the alloy elements are tightly adhered on the porous ceramic material in an atomic state to form the heating element, and preferably, the heating element is covered on the material surface of the aerosol escaping layer facing to the air outlet channel to form another form of composite porous heating sheet.

The heating element can also be a conductive network built in the aerosol escape layer, so that the aerosol escape layer integrally forms the heating element to heat and lead out atomized aerosol.

The heating element can also adopt conductive paste, and the conductive track is printed on the material surface of the aerosol escape layer facing the air outlet channel to form the heating element in a thick film printing mode.

In addition, the composite porous heating sheet in another form can be formed by directly covering the porous ultrathin alloy heating sheet on the material surface of the atomizing core main body facing the air outlet channel in a manner of not including an aerosol escape layer, and enabling alloy elements to be tightly attached to the surface layer of the honeycomb ceramic oil absorption body material in an atomic state in a preferable technical way in manners of vacuum sputtering, vacuum coating and the like. Or, the conductive traces with the preferred patterns are printed on the material surface of the atomizing core body facing the air outlet channel by adopting conductive paste and a thick film printing mode. It is understood that in this way, it is preferable to improve the oil-locking capability of the atomizing core body, for example, by adopting technical measures of reducing the porosity of the atomizing core body, reducing the diameter of the micropores of the atomizing core body, and the like, otherwise, the smoke oil is easy to leak and flow out, and optionally, it is preferable to increase the through holes or blind holes opened at the oil suction surface, and the deterioration of the oil guiding efficiency caused by the through holes or blind holes is eliminated or reduced.

In a second aspect, the present invention also provides an atomiser comprising:

the atomization device comprises a shell, wherein a liquid storage bin for storing atomized liquid is formed in the shell and comprises an outlet; an air outlet channel extending along the lengthwise direction of the shell is formed in the shell and comprises an inlet and an air outlet, and the air outlet of the air outlet channel is positioned at one end of the shell;

optionally an atomizing core as disclosed herein; the atomization core is accommodated in the shell, and the outlet of the liquid storage bin is communicated with the liquid suction surface of the atomization core;

the air inlet channel comprises an air inlet and an air inlet channel outlet, the air inlet channel outlet and the air outlet channel inlet are combined near the heating element to form a communicated airflow channel, and aerosol generated by heating of the heating element is discharged through the airflow channel;

the fixing piece is used for fixing the atomizing core and the shell, and at least one opening communicated with the air inlet of the air inlet channel is formed in the fixing piece;

and the electrode contact is electrically connected with the heating body and used for supplying power to the heating body by a power supply.

Further, there are two air inlet channels, and the electrodes are electrically connected with the heating body through the air inlet channels.

Further, the electrode is electrically connected with the heating element by adopting the air inlet channel.

Furthermore, in a third aspect, the present invention provides an aerosol-generating device comprising:

the power supply assembly is used for providing electric energy for the atomizer, the power supply assembly is electrically connected with the atomizer, and the atomizer is any atomizer disclosed by the invention.

Further, the power supply assembly is electrically connected to the atomizer in a detachable electrical connection.

Compared with the prior art, one side of the heating element is arranged towards the air outlet channel, and at least one air inlet channel is arranged, so that the outlet of the air inlet channel and the inlet of the air outlet channel formed on the shell are converged near the heating element to form a communicated air flow channel, therefore, when a user sucks the aerosol, the air flow channel near the heating element forms negative pressure, at the moment, the air inlet surface of the air inlet oil locking layer is contacted with air, the air can enter the air inlet oil locking layer through the air inlet surface, the air pressure near the first surface side of the atomizing core main body is close to the atmospheric pressure, namely, as the user sucks the aerosol, the air pressure difference is formed on the two sides of the first surface and the second surface of the atomizing core main body, and the air pressure difference is favorable for promoting the atomized liquid absorbed and stored in the atomizing core main body to be conducted to the heating element, so that the atomizing efficiency.

The design of the air inlet channel isolates the direct communication between the atomized liquid and the outside, and further reduces the probability of oil leakage.
