Abstract
Description
Technical Field
[0001] The present application relates to the technical field of aerosol preparation, and in particular to an aerosol generating device and an aerosol generating system. Background Art
[0002] In recent years, as people pay more and more attention to health and quality of life, heated cigarettes and other aerosol generating devices have gradually gained wide attention and application in the market as substitutes for traditional cigarettes. These devices heat the smoking section of the cigarette to volatilize the smoking material and produce inhalable smoke. Compared with burning cigarettes, they can theoretically reduce some harmful components.
[0003] Traditional aerosol generating devices usually use a heating element to heat the aerosol matrix to generate an aerosol for the user to inhale. However, this heating method has a significant problem of long preheating time. Specifically, due to the slow heat transfer rate between the heating element and the aerosol matrix, and the uneven heat transfer inside the aerosol matrix, it takes a long time in the preheating stage for the aerosol matrix to reach a suitable atomization temperature. This not only increases the user's waiting time, but may also cause the temperature of the aerosol smoke generated in the initial stage to be too high, affecting the user experience.
[0004] In addition, some aerosol generating devices have adopted the method of increasing the preheating temperature of the heating element in order to improve the heating efficiency. However, although this method can shorten the preheating time to a certain extent, it may also bring new problems, such as the local part of the aerosol matrix being scorched or burnt, and the water vapor content in the generated aerosol being too high, which seriously reduces the safety of the product and the user experience. Summary of the invention
[0005] Based on this, it is necessary to provide an aerosol generating device that can reduce the preheating time and evenly heat the aerosol.

[0019] In one embodiment, the aerosol generating device further comprises a power module, and the power module is arranged on the flow path of the cooling channel.
[0020] In one of the embodiments, it also includes a heat-insulating layer, and the heat-insulating layer is located at the periphery of the heating chamber.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In the description of this application, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.
[0040] In the present application, unless otherwise clearly specified and limited, a first feature being “above” or “below” a second feature may mean that the first feature is directly in contact with the second feature, or the first feature and the second feature are in contact indirectly through an intermediate medium. Moreover, a first feature being “above”, “above”, or “above” a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature.

[0041] Unless otherwise defined, all technical and scientific terms used in the specification of this application have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used in the specification of this application includes any and all combinations of one or more related listed items.
[0042] See also Figures 1 to 9 The present application provides an aerosol generating device 100, which is used to heat an aerosol product 200 to generate an aerosol that can be inhaled, and includes: a heating component 10, a shell 20 and a preheating component 30, the shell 20 includes a shell 21 with an air inlet 211, the shell 20 has a heating chamber 22, and the heating component 10 is arranged in the heating chamber 22; an air inlet channel 23 is provided between the shell 21 and the heating chamber 22, and the air inlet 211 connects the outside with the heating chamber 22 through the air inlet channel 23; the preheating component 30 is arranged in the air inlet channel 23, and is used to heat the gas entering the heating chamber 22 through the air inlet 211.
[0043] As can be seen from the above, the air is preheated by the preheating component 30, and the air enters from the air inlet 211 and the residual heat of the preheating component 30 flows along the air inlet channel 23 to the heating chamber 22. The preheated air can increase the temperature of the aerosol product 200 in the heating chamber 22, thereby shortening the preheating time, and can also prevent the lower temperature air from directly contacting the heated matrix segment 230, causing premature condensation of the aerosol. At the same time, the entry of the preheated air can also accelerate the flow of gas in the heating chamber 22, thereby generating a thermal convection effect, which can further shorten the preheating time. In addition, the entry of the preheated air can also improve the heating uniformity of the heated aerosol product 200, effectively improve the aerosol suction taste, and improve the user experience.
[0044] Here, the heating component 10 can adopt an internal heating mode or an external heating mode. In the internal heating mode, the heating component 10 is usually placed inside the heating chamber 22, so that the heat can directly and centrally act on the tobacco material, thereby improving the heating efficiency. In addition, the internal heating method is more flexible in product design, and the position and shape of the heating component 10 can be adjusted as needed to adapt to different tobacco materials and heating requirements. The external heating mode heats the aerosol product 200 through an external heat source, which can more easily achieve stable temperature control and reduce the impact of temperature fluctuations on the tobacco heating effect. In addition, the preheating method is suitable for various types of tobacco materials and heating requirements, and has high applicability and flexibility. The preheating component 30 provided in the present application has good applicability to structures such as the internal heating mode and the external heating mode. In addition, the shape of the heating component 10 can be needle-shaped, rod-shaped, or sheet-shaped, and the heating component 10 can be composed of ceramics, electric heating wires, or printed circuits.
[0045] In one embodiment, the shell 20 further has a accommodating chamber 24, and the accommodating chamber 24 and the heating chamber 22 are arranged along the length direction of the shell 21, and the heating chamber 22 is located below the accommodating chamber 24, and the accommodating chamber 24 is used to accommodate the cooling section 210 and the supporting section 220 of the aerosol product 200. The preheating component 30 is a semiconductor element 31 based on the Peltier effect, and the semiconductor element 31 is located between the shell 21 and the heating chamber 22; and / or is located between the shell 21 and the accommodating chamber 24, and the semiconductor element 31 has a hot end 311 and a cold end 312, the hot end 311 is used to heat the gas, and the cold end 312 has a cooling effect.
[0046] It should be noted that the Peltier Effect is a thermoelectric effect. When current passes through a junction composed of two different conductive materials, the two ends of the junction absorb or release heat, thereby achieving a cooling or heating effect. Specifically, the semiconductor element 31 is composed of an insulating heat conductor 313, a conductor 314, a P-type semiconductor 315, and an N-type semiconductor 316. The conductor 314 and the wire connect the N-type semiconductor 316 and the P-type semiconductor 315 into a loop, connecting the semiconductor element 31 to the battery, and the conductor 314 and the wire only play a conductive role. After the semiconductor element 31 is connected to the current, an electron-hole pair is generated at one end, the internal energy is reduced, the temperature is lowered, and heat is absorbed from the outside, which is called the cold end 312; the other end increases the internal energy and the temperature due to the recombination of the electron-hole pairs, and releases heat to the surrounding, which is called the hot end 311.
[0047] It can be understood that the insulating heat conductor 313 is composed of a material with electrical insulation and high thermal conductivity, such as ceramics and glass. The conductor 314 has a conductive property. The N-type semiconductor 316 is a semiconductor that mainly conducts electricity through electrons, such as a silicon semiconductor containing pentavalent element arsenic. The P-type semiconductor 315 is a semiconductor that mainly conducts electricity through holes, such as a silicon semiconductor containing trivalent element boron.
[0048] like Figure 1 As shown, in the first embodiment, the semiconductor element 31 is located between the housing 21 and the accommodating cavity 24, and a preheating channel 32 is formed between the semiconductor element 31 and the housing 21, the hot end 311 faces the preheating channel 32, and the air inlet 211 is opened at the top of the housing 20. Air enters through the air inlet 211 at the top of the housing 20, is heated by the semiconductor element 31, and flows into the heating cavity 22 through the air inlet channel 23, which can increase the temperature of the heating cavity 22.
[0049] like Figures 2 to 6 As shown, in another embodiment, a preheating channel 32 is formed between the semiconductor element 31 and the heating chamber 22, the hot end 311 of the semiconductor faces the preheating channel 32, and the air inlet 211 is opened at the top of the housing 20 or flush with the boundary line between the accommodating chamber 24 and the heating chamber 22. The air enters the housing 20 from the air inlet 211, and enters the heating chamber 22 after being preheated by the semiconductor element 31. The preheated air can increase the temperature of the aerosol product 200, and accelerate the flow of the air in the preheating channel 32 and the gas in the heating chamber 22, thereby generating a thermal convection effect, shortening the preheating time, and improving the uniformity and efficiency of heating.
[0050] It should be noted that the air preheating effect is related to parameters such as the number and power of the semiconductor elements 31 and parameters such as the length and width of the air intake channel 23. Those skilled in the art can adjust the corresponding semiconductor element 31 parameters and air intake channel 23 parameters according to the application scenario.
[0051] like Figure 1 As shown, in one embodiment, when the semiconductor element 31 is located in the accommodating cavity 24, the cold end 312 is arranged toward the accommodating cavity 24, so that the cold end 312 can be used to cool the air in the accommodating cavity 24, so that the inlet smoke temperature is lower, thereby improving the user experience.
[0052] like Figure 3 As shown, in another embodiment, the cold end 312 of the semiconductor element 31 can also be attached to the inner wall of the outer shell 21. The inner wall of the outer shell 21 is cooled by the cold end 312 to prevent the outer shell 21 from being overheated and causing burns to the user, thereby improving the user's experience of holding the aerosol generating device 100.
[0053] like Figure 2 , Figure 4 and Figure 5 As shown, in another embodiment, the cold end 312 of the semiconductor element 31 can also be arranged toward the shell 21, and the hot end 311 of the semiconductor element 31 is arranged toward the heating chamber 22, a cooling channel 33 is formed between the semiconductor element 31 and the shell 21, and a preheating channel 32 is formed between the semiconductor element 31 and the heating chamber 22, the cooling channel 33 and the preheating channel 32 are both connected to the heating chamber 22, and the air inlet 211 is opened at the top of the shell 20 or flush with the boundary line between the accommodating chamber 24 and the heating chamber 22.
[0054] like Figure 5 and Figure 6 As shown, the aerosol generating device 100 further includes a power module 40, which is disposed on the flow path of the cooling channel 33. Since the power module 40 is affected by the cold end 312, the temperature of the side close to the semiconductor element 31 can be effectively reduced. Therefore, the problem of reduced service life of the power supply due to overheating can be improved.
[0055] It should be noted that the power module 40 can be set on one side or on both sides. The figure only shows the installation position of the power module 40. The specific size of the power module 40 or the proportional size of related components can be selected by technical personnel in this field according to the actual application scenario.
[0056] In one embodiment, the aerosol generating device 100 further includes a heat preservation layer 50 , and the heat preservation layer 50 is located outside the heating chamber 22 .
[0057] Specifically, the thermal insulation layer 50 includes a vacuum layer and a heat insulation layer, the vacuum layer is arranged outside the heating chamber 22, and the heat insulation layer is arranged inside the shell 20. Here, the heat insulation layer can be configured as any one or more materials such as aerogel, asbestos, rock wool, glass fiber wool felt, etc.
[0058] The present application also provides the following technical solution: an aerosol generating system 300, comprising an aerosol product 200 and an aerosol generating device 100 of any one of the above-mentioned embodiments, wherein the shell 20 also has a accommodating chamber 24, the accommodating chamber 24 and the heating chamber 22 are arranged along the length direction of the shell 21, and the heating chamber 22 is located below the accommodating chamber 24, and the accommodating chamber 24 accommodates the aerosol product 200.
[0059] Please refer to Fig. 9 , the aerosol product 200 includes a cooling section 210, a support section 220, and a matrix section 230. Among them, the cooling section 210 can be used to reduce the temperature of the smoke and improve the comfort of smoking. Exemplarily, the cooling section 210 contains cooling materials or is designed with special structures such as a conical cavity, an annular conical cavity, etc. to accelerate the flow of airflow and reduce the temperature. The support section 220 can be a hollow tube structure for supporting and fixing other components, such as smoke-generating substances. The support section 220 has specific air permeability to allow air circulation and adjust the temperature, humidity and inhalation resistance of the smoke. The matrix section 230 is the part of the cigarette that produces smoke. For heat-not-burn cigarettes, it usually contains tobacco or other substances that can heat and generate smoke. During the heating process, the substances in the matrix section 230 release aroma and smoke.
[0060] The technical features of the above embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0061] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the scope of patent protection of the present application shall be subject to the attached claims.
