When the outer shell is arranged on the lower portion of the shell in a sleeving mode, the lower portion of the shell and the atomization base assembly can be covered through the outer shell, at the moment, due to the fact that the part, exposed out of the outer shell, of the shell has light transmission performance, and the upper end face of the atomization base assembly is flush with the upper end face of the outer shell, external light can illuminate the whole liquid storage bin; a user can visually and clearly observe the residual amount of the atomized liquid in the liquid storage bin through the shell from the outside, and when the user observes the atomized liquid in the liquid storage bin through the shell, the visual sense of the user is clear and simple in hierarchy, the visual sense of the user cannot be disturbed or confused due to disordered and complex hierarchy, and the user experience is improved. The accuracy of judging the residual amount of the atomized liquid in the liquid storage bin by a user can be improved.

Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of atomization, in particular, relates to an atomizer and an aerosol generating device. BACKGROUND

[0002] The aerosol generating device generally comprises an atomizer and a power supply device electrically connected with the atomizer, and the atomizer can heat and atomize the atomization liquid stored in the atomizer to form an aerosol under the electric driving of the power supply device. At present, due to the influence of factors such as the size and position of the exposed part, the external light usually cannot illuminate the entire liquid storage bin, so that the user cannot directly observe the amount of atomization liquid in the liquid storage bin through the partially transparent exposed part, thereby causing the user to be difficult to accurately judge the remaining amount of atomization liquid in the liquid storage bin. When the atomization liquid in the liquid storage bin is insufficient, if the atomization liquid is not added in time or the atomizer is stopped, dry burning may occur, which affects the user's experience.

Therefore, the phrases "in one embodiment," "in some embodiments," or "in some of these embodiments" appear in various places throughout the specification, and not all refer to the same embodiment. Furthermore, in one or more embodiments, specific features, structures, or characteristics may be combined in any suitable manner.

[0053] Please refer to the following: Figures 1 to 7 The atomizer provided in the embodiments of the present invention will now be described. The atomizer provided in the embodiments of the present invention is applicable to aerosol generating devices. The aerosol generating device mentioned in the embodiments of the present invention generally includes an atomizer and a power supply device 10 electrically connected to the atomizer. When using the aerosol generating device, the power supply device 10 can provide electrical energy to the atomizer. Under the action of electric drive, the atomizing core 3 of the atomizer atomizes the atomizing liquid stored in the atomizer to form an aerosol that can be inhaled by the user.

[0054] Please refer to further details. Figure 1 , Figure 2 and Figure 7The atomizer provided in this embodiment of the invention includes an atomizing cartridge body 1, a limiting member 2, an atomizing core 3, and a shell 60. The atomizing cartridge body 1 includes a shell 11 with a liquid storage chamber 13 inside and an atomizing seat assembly 12 connected to the bottom opening of the shell 11. The atomizing seat assembly 12 forms the bottom of the liquid storage chamber 13. The limiting member 2 is disposed in the liquid storage chamber 13 and is connected to both the shell 11 and the atomizing seat assembly 12. An atomizing channel 21 is formed inside the limiting member 2. The shell 11 is provided with an air outlet 14 for aerosol to flow out, and the atomizing seat assembly 12 is provided with an air inlet 15 for introducing external air. The atomizing channel 21 communicates with both the air outlet 14 and the air inlet 15. The atomizing core 3 is disposed in the atomizing channel 21. The atomizing core 3 can atomize the atomizing liquid to form an aerosol, and the atomized aerosol can be released into the atomizing channel 21. It should be noted that in some specific application scenarios, the atomizing core 3 can be a cotton atomizing core 3 or a ceramic atomizing core 3. Of course, the atomizing core 3 can also be other types of atomizing core 3, and this embodiment does not limit it to only one. Specifically, the atomizing core 3 includes a heating element that heats up after being powered on and a liquid guiding element that transmits atomized liquid to the heating element. The limiting member 2 is provided with a liquid inlet 22 communicating with the liquid storage chamber 13, and the atomized liquid in the liquid storage chamber 13 can be transmitted to the atomizing core 3 through the liquid inlet 22. The outer shell 60 is sleeved on the lower part of the housing 11, and the lower part of the housing 11 can be covered by the outer shell 60. Because the portion of the housing 11 exposed outside the outer shell 60 is translucent, and the atomizing seat assembly 12 is located inside the outer shell 60 with its upper surface flush with the upper surface of the outer shell 60, external light can illuminate the entire liquid storage chamber 13. Users can then observe the remaining amount of atomized liquid in the liquid storage chamber 13 more intuitively and clearly through the portion of the housing 11 exposed outside the outer shell 60. Furthermore, when users observe the atomized liquid in the liquid storage chamber 13 through the housing 11, the visual perception is clear and simple.

[0055] The atomizer provided in this embodiment of the invention, compared with the prior art, provides a liquid storage chamber 13 in the shell 11 of the atomizing cartridge body 1, and connects the atomizing seat assembly 12 of the atomizing cartridge body 1 to the bottom opening of the shell 11, so that the atomizing seat assembly 12 forms the bottom of the liquid storage chamber 13. When the outer shell 60 is fitted onto the lower part of the shell 11, the lower part of the shell 11 and the atomizing seat assembly 12 can be covered by the outer shell 60. At this time, since the part of the shell 11 exposed outside the outer shell 60 is light-transmitting, and the upper end surface of the atomizing seat assembly 12 is flush with the upper end surface of the outer shell 60, external light can illuminate the entire liquid storage chamber 13. The user can not only observe the remaining amount of atomized liquid in the liquid storage chamber 13 more intuitively and clearly through the shell 11, but also the user's visual perception is clear and simple when observing the atomized liquid in the liquid storage chamber 13 through the shell 11, without causing interference or confusion in the user's visual perception, thereby improving the accuracy of the user's judgment of the remaining amount of atomized liquid in the liquid storage chamber 13.

[0056] Understandably, in some embodiments, the atomizing liquid is a colored liquid, and the housing 11 is a transparent component made of a colorless and transparent material. In some specific application scenarios, the housing 11 can be, but is not limited to, a transparent glass or transparent plastic component, allowing external light to pass through the housing 11 and illuminate the entire reservoir 13. Furthermore, the colored liquid of the atomizing liquid creates a striking color contrast with the housing 11, allowing the user to more intuitively and clearly observe the remaining amount of atomizing liquid in the reservoir 13 from the outside, further improving the accuracy of the user's judgment of the remaining amount of atomizing liquid in the reservoir 13. Of course, in other specific application scenarios, the atomizing liquid is a colored liquid, and the housing 11 can also be a light-transmitting component made of a colored light-transmitting material, as long as the color of the housing 11 is different from the color of the atomizing liquid.

[0057] Understandably, in some embodiments, the outer casing 60 is a colored, opaque component made of an opaque material. In some specific applications, the outer casing 60 can be, but is not limited to, an opaque plastic, metal, or glass component, so that the outer casing 60 can provide good coverage of the lower part of the housing 11 and the atomizing seat assembly 12. This ensures that when the user observes the atomized liquid in the storage tank 13 through the housing 11, the visual perception is clear and simple, without causing interference or confusion in the user's visual perception, thereby improving the accuracy of the user's judgment of the remaining amount of atomized liquid in the storage tank 13. Of course, in other specific applications, the outer casing 60 can also be a light-transmitting component made of light-transmitting materials such as light-transmitting glass or light-transmitting plastic, requiring only a colored, opaque covering layer to be applied to the outer casing 60.

[0058] Please refer to further details. Figure 2 , Figure 3 and Figure 7In some embodiments, the atomizing base assembly 12 includes a base 121 and a first seal 122. The base 121 is fitted into the bottom opening of the housing 11, and the first seal 122 is located in the liquid storage chamber 13 and supported on the base 121. The first seal 122 forms the bottom of the liquid storage chamber 13, and the side of the first seal 122 facing away from the base 121 is flush with the upper surface of the housing 60. In this embodiment, through the above structural arrangement, not only can the remaining amount of atomized liquid in the liquid storage chamber 13 be observed more intuitively and clearly from the outside through the housing 11, but also, when observing the atomized liquid in the liquid storage chamber 13 through the housing 11, the user's visual perception is clear and simple, without causing interference or confusion from the user's visual perception, thereby improving the accuracy of the user's judgment of the remaining amount of atomized liquid in the liquid storage chamber 13. It should be noted that, since the first seal 122 forms the bottom of the liquid storage chamber 13, the side of the first seal 122 facing away from the base 121 is flush with the upper surface of the outer shell 60. This avoids the situation where the first seal 122 protrudes from the upper surface of the outer shell 60. In this case, the boundary line between the upper surface of the outer shell 60 and the first seal 122, as well as the boundary line between the upper surface of the first seal 122 and the atomized liquid, can be seen through the outer shell 11 from the outside, resulting in a visually layered and less minimalist appearance. On the other hand, it also avoids the situation where the first seal 122 is lower than the upper surface of the outer shell 60. In this case, the boundary line between the upper surface of the first seal 122 and the atomized liquid, as well as the inner surface of the outer shell 60 between the upper surface of the outer shell 60 and the upper surface of the first seal 122, can be seen through the outer shell 11 from the outside, resulting in a visually layered and less minimalist appearance.

[0059] In some embodiments, the atomizing liquid is a colored liquid, and the first seal 122 is a transparent gasket made of a colorless and transparent material. In some specific applications, the first seal 122 can be a transparent gasket made of colorless and transparent materials such as transparent silicone or transparent rubber. The contrast between the colored liquid and the first seal 122 allows the user to more intuitively and clearly observe the remaining amount of atomizing liquid in the reservoir 13 through the outer casing 11, further improving the accuracy of the user's judgment of the remaining amount of atomizing liquid in the reservoir 13. Of course, in other specific applications, the atomizing liquid is a colored liquid, and the first seal 122 can also be an opaque gasket made of opaque colored and opaque materials such as opaque silicone or opaque rubber, as long as the color of the first seal 122 is different from the color of the atomizing liquid.

[0060] Please refer to further details. Figure 1 , Figure 2 and Figure 7In some embodiments, the inner edge of the upper surface of the housing 60 is flush with the outer edge of the upper surface of the atomizing seat assembly 12, so that the transition between the inner edge of the upper surface of the housing 60 and the outer edge of the upper surface of the atomizing seat assembly 12 is natural. When observing the atomized liquid in the storage tank 13 through the housing 11, the user's visual perception is clear and simple, and it will not cause interference or confusion in the user's visual perception, thereby improving the accuracy of the user's judgment on the remaining amount of atomized liquid in the storage tank 13.

[0061] Please refer to further details. Figure 1 , Figure 2 and Figure 7 In some embodiments, the limiting member 2 is a limiting tube with an internal atomization channel 21. The limiting tube is provided with a liquid inlet 22, the housing 11 is provided with an air outlet 14, and the atomizing seat assembly 12 is provided with an air inlet 15. The atomization channel 21 is connected to the air inlet 15 and the air outlet 14 respectively. The part of the housing 11 outside the limiting tube defines a liquid storage chamber 13. When using the atomizer, the atomized liquid in the liquid storage chamber 13 can be transferred to the atomizing core 3 through the liquid inlet 22. After being powered on, the atomizing core 3 can atomize the atomized liquid to form an aerosol. The atomized aerosol of the atomizing core 3 can be released into the atomization channel 21. The user only needs to inhale through the air outlet 14. Under the negative pressure created by the user's inhalation, external air is introduced into the atomization channel 21 through the air inlet 15. The aerosol in the atomization channel 21 is carried to the air outlet 14 by the suction airflow and finally enters the user's mouth and is inhaled by the user.

[0062] Please refer to further details. Figure 1 , Figure 2 and Figure 7 In some embodiments, the housing 11 is further provided with a suction tube 8 that connects the atomization channel 21 and the air outlet 14. The first end of the suction tube 8 is connected to the housing 11, and the second end of the suction tube 8 is connected to the first end of the limiting tube. The atomizing seat assembly 12 is provided with a positioning groove 19, and the second end of the limiting tube is inserted into and positioned in the positioning groove 19. In this embodiment, by providing a positioning groove 19 on the first sealing member 122 of the atomizing seat assembly 12, the limiting tube can be securely installed in the liquid storage chamber 13 simply by inserting and positioning the second end of the limiting tube into the positioning groove 19, which helps to enhance the stability of the atomizing core 3 installation.

[0063] Please refer to further details. Figure 1 , Figure 6 and Figure 7In some embodiments, the first end of the limiting tube is provided with a flared tube 23, and the second end of the suction tube 8 is inserted into the flared tube 23. In this embodiment, with the flared tube 23 at the first end of the limiting tube, the third sealing element 9 only needs to be fitted onto the second end of the suction tube 8 and the second end of the suction tube 8 inserted into the flared tube 23 to quickly achieve a matching connection between the limiting tube and the suction tube 8, while enhancing the stability and sealing of the connection between the limiting tube and the suction tube 8. It should be noted that in some specific application scenarios, the third sealing element 9 can be a sealing ring made of silicone or rubber, or a sealing sleeve made of silicone or rubber.

[0064] Please refer to further details. Figure 1 , Figure 2 and Figure 3 In some embodiments, the atomizing bullet body 1 is also provided with a liquid injection channel 17 communicating with the liquid storage chamber 13, through which the user can add atomizing liquid to the liquid storage chamber 13. The atomizer also includes a liquid injection plug 30 for insertion into the liquid injection channel 17. After the liquid injection is completed, the liquid injection plug 30 can be inserted into the liquid injection channel 17 to seal the liquid injection channel 17. Specifically, in some specific application scenarios, the base 121 of the atomizing seat assembly 12 is provided with a first through hole 171, and the first sealing member 122 of the atomizing seat assembly 12 is provided with a second through hole 172. The first through hole 171 and the second through hole 172 communicate to form the liquid injection channel 17.

[0065] Please refer to further details. Figure 8 and Figure 9The liquid guiding component 32 provided in this embodiment of the invention includes a first liquid guiding layer 321 and a second liquid guiding layer 322. The first liquid guiding layer 321 is used to contact the heating element 31 of the atomizing core 3, so that the heating element 31 of the atomizing core 3 can heat and atomize the atomized liquid adsorbed and / or stored in the first liquid guiding layer 321. The second liquid guiding layer 322 is stacked on the side of the first liquid guiding layer 321 facing away from the heating element 31, so that the atomized liquid adsorbed by the second liquid guiding layer 322 can be uniformly transferred to the first liquid guiding layer 321. In order to overcome the defect of poor high temperature resistance of traditional liquid suction components, the first liquid guiding layer 321 is a heat-resistant layer disposed between the heating element 31 and the second liquid guiding layer 322. The first liquid guiding layer 321, as a heat-resistant layer, is made of a high temperature resistant material. At the same time, the first liquid guiding layer 321, as a heat-resistant layer, has good liquid guiding performance. Therefore, the entire liquid guiding component 32 has both good high temperature resistance and good liquid guiding performance and is not easily scorched. Furthermore, the first liquid-conducting layer 321, which serves as the heat-resistant layer, has excellent liquid storage performance, namely, a liquid storage capacity of 35-50 mg / min. At the same time, the liquid conduction rate of the second liquid-conducting layer 322 is greater than that of the first liquid-conducting layer 321. This effectively overcomes the shortcomings of slow liquid absorption and conduction rates of traditional liquid-absorbing components, ensuring that the liquid absorption and conduction rates of the liquid-conducting component 32 can meet the normal atomization operation of the heating element 31. The situation where the liquid absorption and conduction rates of the liquid-conducting component are too slow will not occur. Therefore, it can effectively solve the problem of dry burning of the heating element 31 caused by untimely liquid supply from the liquid-conducting component.

[0066] It should be noted that in some specific application scenarios, the heat-resistant layer can be, but is not limited to, linen cotton. The process of conducting a lateral liquid conduction test on the linen cotton is as follows: a single layer of linen cotton is suspended vertically, and the linen cotton is brought into contact with the atomized liquid in the vertical direction. A camera captures the height (in mm / 3s) of the atomized liquid wetting the single layer of linen cotton within 3 seconds. After the atomized liquid climbs along the vertically suspended linen cotton for 1 minute, the atomized liquid is removed. The liquid storage capacity of the heat-resistant layer is reflected by examining the mass of atomized liquid adsorbed by the single layer of linen cotton (in mg / min). In this embodiment of the invention, using the above-described lateral liquid conduction test method, the liquid storage capacity of the first liquid-conducting layer 321 can be measured to be 35–50 mg / min, and the lateral liquid conduction rate of the first liquid-conducting layer 321 is 3–3.5 mm / 3s.

[0067] Understandably, in some specific application scenarios, the second liquid-conducting layer 322 can be, but is not limited to, porous cotton such as long-grain wood pulp cotton or non-woven fabric, and the basis weight of the second liquid-conducting layer 322 is 45-55 g / m³. 2 Therefore, the second liquid guiding layer 322 has a higher liquid absorption rate and liquid guiding rate than the first liquid guiding layer 321, thereby accelerating the liquid absorption rate and liquid guiding rate of the liquid guiding component 32, so that the liquid guiding component 32 can quickly transfer the atomized liquid to the heating component 31.

[0068] Compared with the prior art, the liquid guiding component provided in this embodiment of the invention has a first liquid guiding layer 321 spaced between the heating element 31 and the second liquid guiding layer 322. The first liquid guiding layer 321 is a heat-resistant layer made of a high-temperature resistant material. By having the first liquid guiding layer 321, which serves as a heat-resistant layer, in contact with the heating element 31, the high-temperature resistance of the liquid guiding component 32 can be improved, thereby effectively preventing the liquid guiding component 32 from being scorched and producing a burnt smell. Furthermore, the liquid storage capacity of the first liquid guiding layer 321 is 35-50 mg / min, and the liquid guiding rate of the second liquid guiding layer 322 is greater than that of the first liquid guiding layer 321. This can accelerate the liquid absorption rate and liquid guiding rate of the liquid guiding component 32, enabling the liquid guiding component 32 to quickly transfer the atomized liquid to the heating element 31. This avoids the heating element 31 from dry burning due to insufficient liquid supply or interruption of liquid delivery, thereby further effectively preventing the liquid guiding component 32 from being scorched and producing a burnt smell.

[0069] In some embodiments, a first liquid guiding layer 321 is provided between the heating element 31 and the second liquid guiding layer 322, and the basis weight of the first liquid guiding layer 321 is 54-66 g / m³. 2 Since the first liquid guiding layer 321 is a heat-resistant layer separated between the heating element 31 and the second liquid guiding layer 322, and the first liquid guiding layer 321, as a heat-resistant layer, is made of high-temperature resistant material, the entire liquid guiding element 32 has better high-temperature resistance and will not cause scorching.

[0070] Please refer to the following: Figure 8 In some other embodiments, two first liquid-conducting layers 321 are provided between the heating element 31 and the second liquid-conducting layer 322. Since the first liquid-conducting layer 321 is a heat-resistant layer disposed between the heating element 31 and the second liquid-conducting layer 322, and the first liquid-conducting layer 321 as a heat-resistant layer is made of a high-temperature resistant material, the high-temperature resistance of the entire liquid-conducting element 32 can be further improved by providing two heat-resistant layers between the heating element 31 and the second liquid-conducting layer 322. It should be noted that since the liquid conduction rate of the first liquid-conducting layer 321 as a heat-resistant layer is less than that of the second liquid-conducting layer 322, when three or more heat-resistant layers are provided between the heating element 31 and the second liquid-conducting layer 322, although the high-temperature resistance of the entire liquid-conducting element 32 can be enhanced, the liquid conduction performance of the entire liquid-conducting element 32 will be significantly reduced, which may easily cause the heating element 31 to dry-burn due to insufficient liquid supply or interruption of liquid delivery.

[0071] Understandably, in some embodiments, the sum of the thicknesses of the first liquid guiding layer 321 and the second liquid guiding layer 322 is 0.7 to 1.2 mm, that is, the sum of the thicknesses of the first liquid guiding layer 321 and the second liquid guiding layer 322 can be 0.7 mm, 0.9 mm or 1.2 mm, etc. Since the liquid guiding component 32 is compressed after being installed in the limiting tube, the thickness of the liquid guiding component 32 changes, which has a certain impact on the liquid guiding rate of the liquid guiding component 32. Therefore, the sum of the thicknesses of the first liquid guiding layer 321 and the second liquid guiding layer 322 is controlled at 0.7 to 1.2 mm. This ensures that the liquid guiding component 32 still has a good liquid guiding rate after being compressed and assembled in the limiting tube. That is, the radial liquid guiding rate of the compressed liquid guiding component 32 can be controlled at 0.3 to 1 mg / min. This allows the liquid guiding component 32 to quickly transfer the atomizing liquid to the heating element 31, avoiding dry burning of the heating element 31 due to insufficient liquid supply or interruption of liquid delivery. Therefore, it can effectively prevent the liquid guiding component 32 from being burned and producing a burnt smell. It should be noted that the radial liquid conduction rate test process of the liquid guide 32 is as follows: the liquid guide 32 with a thickness of 0.7 to 1.2 mm is compressed to a thickness of 0.6 mm. The radial liquid conduction rate (unit: mg / min) of the liquid guide 32 is reflected by collecting and recording the mass of the atomized liquid that permeates through the compressed liquid guide 32 at room temperature and pressure.

[0072] Please refer to the following: Figure 10 In some embodiments, the porous cotton sheath layer is provided with multiple through holes 34 for conveying atomized liquid, and the spacing between two adjacent through holes 34 is equal. The atomized liquid adsorbed by the porous cotton sheath layer can be directly conveyed to the flax cotton sheath layer through the through holes 34, which can accelerate the rate of atomized liquid conveying to the flax cotton sheath layer. This helps to overcome the shortcomings of the slow liquid absorption and conduction rates of traditional liquid absorbers, ensuring that the liquid absorption and conduction rates of the liquid guide 32 can meet the atomization work of the heating element 31, and preventing the liquid absorption and conduction rates of the liquid absorber from being too slow. This effectively solves the problem of the heating element 31 dry burning due to untimely liquid supply. Understandably, in some specific application scenarios, in order to ensure that the atomized liquid adsorbed by the porous cotton sheath layer can be quickly and uniformly conveyed to the flax cotton sheath layer through the through holes 34, the opening density of the through holes 34 is 40 to 100 per square centimeter.

[0073] Please refer to further details. Figure 8 and Figure 9The liquid guiding component 32 provided in this embodiment of the invention includes a first liquid guiding layer 321 and a second liquid guiding layer 322. The first liquid guiding layer 321 is used to contact the heating element 31 of the atomizing core 3, so that the heating element 31 of the atomizing core 3 can heat and atomize the atomized liquid adsorbed and / or stored in the first liquid guiding layer 321. The second liquid guiding layer 322 is stacked on the side of the first liquid guiding layer 321 facing away from the heating element 31, so that the atomized liquid adsorbed by the second liquid guiding layer 322 can be uniformly transferred to the first liquid guiding layer 321. To overcome the shortcomings of slow liquid absorption and conduction rates in traditional liquid-absorbing components, multiple through holes 34 for transmitting atomized liquid are provided on the second liquid-conducting layer 322. The atomized liquid adsorbed by the second liquid-conducting layer 322 can be directly transmitted to the first liquid-conducting layer 321 through the through holes 34, which can accelerate the rate at which the atomized liquid is transmitted to the first liquid-conducting layer 321. This helps to overcome the shortcomings of slow liquid absorption and conduction rates in traditional liquid-absorbing components, ensuring that the liquid absorption and conduction rates of the liquid-conducting component 32 can meet the atomization work of the heating element 31. The situation of slow liquid absorption and conduction rates of the liquid-absorbing component will not occur. This can effectively solve the problem that when the heating element 31 has insufficient liquid supply or interruption, the aerosol generated after atomization is too dry and weak, resulting in insufficient aroma release, or even the heating element 31 will dry-burn, causing the liquid-absorbing component to be scorched and producing a burnt smell. In some specific application scenarios, the multiple through holes 34 can be arranged in a random or ordered manner on the second liquid guiding layer 322. Furthermore, to overcome the poor high-temperature resistance of traditional liquid-absorbing components, the first liquid guiding layer 321 is a heat-resistant layer separated from the heating element 31 and the second liquid guiding layer 322. The first liquid guiding layer 321, as a heat-resistant layer, is made of a high-temperature resistant material and possesses both good liquid guiding and liquid-absorbing properties. Therefore, the entire liquid guiding component 32 combines excellent high-temperature resistance and good liquid guiding properties, making it less prone to scorching.

[0074] Compared with the prior art, the liquid guiding component provided in this embodiment of the invention has a first liquid guiding layer 321 spaced between the heating element 31 and the second liquid guiding layer 322, and multiple through holes 34 arranged on the second liquid guiding layer 322 in a disordered or ordered arrangement. This allows the atomized liquid adsorbed by the second liquid guiding layer 322 to be directly transferred to the first liquid guiding layer 321 through the through holes 34, which can accelerate the rate at which the atomized liquid is transferred to the first liquid guiding layer 321. This helps to overcome the shortcomings of slow liquid absorption and liquid guiding rates in traditional liquid absorption components, improves the problem of insufficient aroma release due to dry and weak aerosols, and avoids dry burning of the heating element 31 due to insufficient liquid supply or interruption of liquid delivery. It also helps to prevent the liquid guiding component 32 from being burned and producing a burnt smell. Furthermore, the first liquid guiding layer 321 is a heat-resistant layer made of a high-temperature resistant material. By having the first liquid guiding layer 321, which is a heat-resistant layer, come into contact with the heating element 31, the high-temperature resistance of the liquid guiding element 32 can be improved, thereby further effectively preventing the liquid guiding element 32 from being burned and producing a burnt smell.

[0075] Please refer to the following: Figure 10 In some embodiments, in order to ensure that the atomized liquid adsorbed by the second liquid guiding layer 322 can be quickly and uniformly transferred to the first liquid guiding layer 321 through the through hole 34, the opening density of the through hole 34 is 40 to 100 per square centimeter.

[0076] Please refer to the following: Figure 10 In some embodiments, when multiple through holes 34 are arranged in an ordered manner on the second liquid guiding layer 322, the multiple through holes 34 are arranged in an array, so that the atomized liquid adsorbed by the second liquid guiding layer 322 can be uniformly transferred to the first liquid guiding layer 321 through the through holes 34.

[0077] Please refer to the following: Figure 10 , Figure 11 and Figure 12In some embodiments, when multiple through holes 34 are arranged in an ordered pattern on the second liquid-conducting layer 322, at least three through holes 34 can form an infusion unit. In each infusion unit, the centers of the through holes 34 connected sequentially can form a polygon. The polygon can be a regular polygon or a non-regular polygon. For example, the polygon can be at least one of triangles, rectangles, or rhombuses. When the polygon is a triangle, the triangle can be an isosceles triangle with a leg length L of 1.4–1.8 mm, for example, 1.6 mm, and a base length H of 1.8–2.4 mm, for example, 2.1 mm. Further, the triangle can also be an equilateral triangle, i.e., L = H. Specifically, the through holes 34 can be any one or more of the following: circular, semi-circular, elliptical, quasi-elliptical, rectangular, and triangular. When the through hole 34 is elliptical or quasi-elliptical, the long side a of the ellipse or quasi-ellipse is 1-2 mm, further 1.1-1.7 mm, and the short side b is 0.2-0.6 mm, for example 0.4 mm.

[0078] Understandably, in some embodiments, the first liquid-conducting layer 321 is a flax-cotton sheath wrapped around the heating element 31, and the second liquid-conducting layer 322 is a porous cotton sheath wrapped around the flax-cotton sheath. Because the flax-cotton sheath has excellent high-temperature resistance, and the porous cotton sheath has excellent liquid absorption and conduction properties, the liquid-conducting element 32 possesses both good high-temperature resistance and excellent liquid absorption and conduction properties, thereby effectively preventing the liquid-conducting element 32 from being scorched and producing a burnt smell.

[0079] Please refer to the following: Figure 8 and Figure 9In some embodiments, the liquid guiding element 32 further includes at least one insulating layer 323 disposed between the first liquid guiding layer 321 and the second liquid guiding layer 322, which can isolate odors. Furthermore, from the second liquid guiding layer 322 to the first liquid guiding layer 321, the porosity and / or pore size of the second liquid guiding layer 322, the insulating layer 323, and the first liquid guiding layer 321 exhibit a gradually decreasing trend. Therefore, the entire liquid guiding element 32 utilizes a gradient structure for progressive liquid guiding, which is beneficial for providing a stable atomization environment for the transmission and atomization of the atomizing liquid. Because the porosity and / or pore size of the first liquid guiding layer 321 is small and its porosity and / or pore size distribution is uniform and dense, it can achieve the purpose of refining the atomizing liquid particles, providing more atomizing nuclei, resulting in a uniform temperature distribution on the heating element 31, improving the atomization efficiency of the atomizing liquid, and enhancing the user's inhalation experience of the aerosol. The second liquid guiding layer 322 is in contact with the atomizing liquid. With a larger porosity and / or pore size, the second liquid guiding layer 322 facilitates stable and smooth atomizing liquid transport, controlling and improving the liquid guiding rate. This prevents excessive liquid intake leading to splattering and leakage, and also prevents insufficient liquid intake leading to dry burning and coil burnt. The isolation layer 323 sandwiched between the first liquid guiding layer 321 and the second liquid guiding layer 322 stores the atomizing liquid, shortening the transport distance and facilitating stable and smooth transport of the atomizing liquid to the first liquid guiding layer 321. This not only ensures sufficient liquid supply to the heating element 31 on the first liquid guiding layer 321, meeting the atmospheric atomization requirements, but also prevents insufficient liquid supply to the atomizing core 3, which can lead to dry burning, coil burnt, and carbon buildup. It should be noted that a maximum of two isolation layers 323 may be provided between the liquid guiding layer 321 and the second liquid guiding layer 322.

[0080] Please refer to the following: Figure 9 This invention also provides an atomizing core, which includes a liquid guiding component 32 and a heating element 31 provided in any of the above embodiments. Because the atomizing core possesses all the technical features of the liquid guiding component 32 provided in any of the above embodiments, it has the same technical effects as the liquid guiding component 32. Specifically, in some specific application scenarios, the heating element 31 can be a mesh spiral structure heating element, a mesh heating sheet, a spiral heating wire, a wavy heating element, a mesh heating element, etc.

[0081] Please refer to further details. Figure 1 , Figure 2 and Figure 3The atomizer provided in this embodiment of the invention includes an atomizing bullet body 1, a limiting member 2, an atomizing core 3, and a first isolating member 4. The atomizing bullet body 1 has a cylindrical outer contour and a liquid storage chamber 13 for storing atomized liquid is formed inside the atomizing bullet body 1. The atomizing bullet body 1 is provided with an air outlet 14 for aerosol outflow and an air inlet 15 for introducing external air. The limiting member 2 is disposed in the liquid storage chamber 13 and has an atomizing channel 21 formed inside the limiting member 2. The atomizing channel 21 is connected to the air outlet 14 and the air inlet 15 respectively. A preset position for installing the atomizing core 3 is formed in the atomizing channel 21. The atomizing core 3 is installed at the preset position in the atomizing channel 21. The limiting member 2 is provided with a liquid inlet 22 that connects to the liquid storage chamber 13. The atomized liquid in the liquid storage chamber 13 can be transferred to the atomizing core 3 through the liquid inlet 22.

[0082] Before the atomizer is activated, the first isolator 4 is simply inserted into the atomization channel 21, so that the first isolator 4 abuts against the atomizing coil 3. The first isolator 4, in conjunction with the limiting member 2, then confines the atomizing coil 3 to a preset position within the atomization channel 21. At this point, the atomizing coil 3 is positioned in the preset position within the atomization channel 21 and remains stationary. This ensures that the relative position of the atomizing coil 3 and the atomization channel 21 meets design expectations and has high consistency, thereby improving product consistency. It should be noted that "before the atomizer is activated" includes, but is not limited to, situations during atomizer transportation, storage, or carrying. When the atomizer is needed, simply remove the first isolator 4 from the atomization channel 21. The atomization channel 21 is then opened. Under the negative pressure created by the user's inhalation, external air can be introduced into the atomization channel 21 through the air inlet 15. The aerosol in the atomization channel 21 is first mixed with the air introduced into the atomization channel 21, and then introduced into the air outlet 14 along with the airflow. Finally, it flows out into the user's mouth through the air outlet 14.

[0083] The atomizer provided in this embodiment of the invention, compared with the prior art, provides a liquid storage chamber 13 inside the atomizing cartridge body 1, and a limiting member 2 with an atomization channel 21 inside the liquid storage chamber 13, and installs the atomizing core 3 in a preset position in the atomization channel 21. Before the atomizer is used, only the first isolating member 4 needs to be inserted into the atomization channel 21, so that the first isolating member 4 abuts against the atomizing core 3. The first isolating member 4, together with the limiting member 2, can limit the atomizing core 3 to the preset position in the atomization channel 21, thereby conveniently and quickly positioning and installing the atomizing core 3 in the preset position in the atomization channel 21. This overcomes the defects of existing atomizer structures, such as the difficulty in fixing the atomizing core 3 to the preset position in the atomization channel 21 and the poor stability of the atomizing core 3 installation, resulting in poor consistency of the atomizing core 3 installation. When the atomizer needs to be used, only the first isolating member 4 needs to be removed from the atomization channel 21, and the user can use the atomizer normally, making the operation convenient.

[0084] Please refer to further details. Figure 1 , Figure 2 and Figure 5 In some embodiments, the atomizing core 3 has a through channel 33 formed inside, which extends axially along the atomizing channel 21. A second isolation member 5 is provided on the first isolation member 4 and is inserted into the through channel 33. In this embodiment, before the atomizer is activated, the first isolation member 4 can hold and confine the atomizing core 3 to a preset position in the atomizing channel 21 along the axial direction of the through channel 33. Simultaneously, the second isolation member 5, inserted into the through channel 33, can hold and confine the atomizing core 3 to a preset position in the atomizing channel 21 along the radial direction of the through channel 33. This ensures that the atomizing core 3 is positioned and remains stationary in the preset position in the atomizing channel 21, which not only enhances the stability of the atomizing core 3 installed in the atomizing channel 21 but also improves the consistency of the atomizing core 3 installation. Furthermore, since the second isolation member 5 is inserted into the through channel 33, it provides radial support to the atomizing core 3, preventing the atomizing core 3 from being squeezed and deformed.

[0085] It should be noted that further reference is required. Figure 1 , Figure 3 and Figure 5 When the first isolator 4 is a positioning rod and the second isolator 5 is a positioning rod, the diameter of the positioning rod is larger than the diameter of the positioning rod. The first end of the positioning rod is connected to the first end of the positioning rod to form a supporting surface 20 at the connection between the positioning rod and the positioning rod, which is used to support the top surface of the atomizing core 3. With the above structural arrangement, before the atomizer is activated, when the supporting surface 20 and the top surface of the atomizing core 3 abut against each other, the positioning rod can support and limit the atomizing core 3 in a preset position in the atomizing channel 21 along the axial direction of the through channel 33. At the same time, the positioning rod inserted in the through channel 33 can support and limit the atomizing core 3 in a preset position in the atomizing channel 21 along the radial direction of the through channel 33, thus ensuring that the atomizing core 3 is positioned in the preset position in the atomizing channel 21 and remains stationary. In addition, the first isolator 4 and / or the second isolator 5 can be, but is not limited to, silicone, plastic, metal or rubber.

[0086] Please refer to further details. Figure 1 , Figure 2 and Figure 3 In some embodiments, the atomizing cartridge body 1 is further provided with a positioning hole 16, the first end of the second isolating member 5 is connected to the first end of the first isolating member 4, and the second end of the second isolating member 5 is accommodated and positioned in the positioning hole 16. In this embodiment, by providing a positioning hole 16 on the atomizing cartridge body 1 to cooperate in positioning the second isolating member 5, it is only necessary to accommodate and position the second end of the second isolating member 5 in the positioning hole 16, which helps to enhance the stability of the second isolating member 5 in positioning the atomizing core 3.

[0087] Please refer to further details. Figure 1 , Figure 2 and Figure 3 In some embodiments, the central axes of the positioning hole 16 and the air inlet 15 are collinear. Since the diameter of the air inlet 15 is smaller than the diameter of the positioning hole 16, a step 18 is formed between the positioning hole 16 and the air inlet 15, and the second end of the second isolator 5 abuts against the step 18. In this embodiment, the step 18 formed between the positioning hole 16 and the air inlet 15 can abut against the second end of the second isolator 5, achieving the effect of stopping the second isolator 5. After the first isolator 4 and the second isolator 5 hold and limit the atomizing core 3 to a preset position in the atomizing channel 21, it effectively prevents the first isolator 4 and the second isolator 5 from continuing to move downward, thereby enhancing the stability of the first isolator 4 and the second isolator 5 in positioning the atomizing core 3.

[0088] Please refer to further details. Figure 2 , Figure 5 and Figure 6 In some embodiments, the atomizing core 3 includes a heating element 31 and a liquid guiding element 32 for conveying atomized liquid to the heating element 31. The liquid guiding element 32 is configured as a tubular liquid guiding sleeve, and the heating element 31 is attached to the inner wall of the liquid guiding sleeve. The second isolator 5 is a positioning rod inserted into the liquid guiding sleeve. In this embodiment, configuring the liquid guiding element 32 as a tubular liquid guiding sleeve and configuring the second isolator 5 as a positioning rod, only requiring the positioning rod to be inserted into the liquid guiding sleeve, helps to prevent the heating element 31 or the liquid guiding element 32 of the atomizing core 3 from being squeezed and deformed.

[0089] Please refer to further details. Figure 1 , Figure 4 and Figure 6 In some embodiments, the first isolator 4 is a positioning rod, and the positioning rod is provided with a second sealing element 6, which abuts against the inner wall of the atomizing channel 21. In this embodiment, when the positioning rod is inserted into the atomizing channel 21, the second sealing element 6 abuts against the inner wall of the atomizing channel 21, enhancing the sealing between the positioning rod and the atomizing channel 21 and effectively preventing leakage of the atomized liquid through the atomizing channel 21. Furthermore, during the insertion or removal of the positioning rod, the second sealing element 6 slides against the inner wall of the atomizing channel 21, which helps to improve the reliability of inserting or removing the positioning rod. It should be noted that in some specific application scenarios, the positioning rod and / or the second sealing element 6 can be, but is not limited to, sealing components made of silicone or rubber, and the second sealing element 6 can be a sealing ring or a sealing sleeve.

[0090] Please refer to further details. Figure 1 , Figure 4 and Figure 6In some embodiments, the second end of the first isolator 4 is provided with a push-pull member 7, which is located outside the atomizing cartridge body 1. The user can easily insert the first isolator 4 into the atomizing channel 21 via the air outlet 14, or easily pull the first isolator 4 out of the atomizing channel 21, simply by using the external push-pull member 7 exposed outside the atomizing cartridge body 1. It should be noted that the push-pull member 7 can be a push-pull rod or a push-pull ring connected to the second end of the first isolator 4.

[0091] Please refer to further details. Figure 1 , Figure 2 and Figure 6 In some embodiments, the atomizing bullet body 1 includes a cylindrical shell 11 and an atomizing seat assembly 12 disposed on the end opening of the shell 11. Specifically, the atomizing base assembly 12 includes a base 121 disposed on the end opening of the housing 11 and a first sealing member 122 disposed in the housing 11 and supported on the base 121. The top of the housing 11 is provided with an air outlet 14. The limiting member 2 is a limiting tube with an atomizing channel 21 formed inside. The atomizing core 3 is disposed in the atomizing channel 21. The base 121 is provided with an air inlet 15. The first sealing member 122 is provided with a positioning hole 16 connecting the air inlet 15 and the atomizing channel 21. The part inside the housing 11 outside the limiting tube defines a liquid storage chamber 13. The limiting tube is provided with a liquid delivery hole 22 communicating with the liquid storage chamber 13. The atomizing liquid in the liquid storage chamber 13 can be transferred to the atomizing core 3 through the liquid delivery hole 22. After being powered on, the atomizing core 3 can atomize the atomizing liquid to form an aerosol. The atomized aerosol of the atomizing core 3 can be released into the atomizing channel 21. When using the atomizer, the user inhales through the air outlet 14. Under the negative pressure created by the user's inhalation, external air is introduced into the atomization channel 21 through the air inlet 15 and the positioning hole 16. The aerosol in the atomization channel 21 is carried to the air outlet 14 by the suction airflow and finally enters the user's mouth and is inhaled by the user.

[0092] Please refer to further details. Figure 1 , Figure 2 and Figure 6The atomizer provided in this embodiment of the invention includes an atomizing bullet body 1, an airway assembly 50, an atomizing core 3, and an isolation assembly 40. The atomizing bullet body 1 has a cylindrical outer contour and a liquid storage chamber 13 for storing atomized liquid is formed inside the atomizing bullet body 1. The atomizing bullet body 1 is provided with an air outlet 14 and an air inlet 15. The airway assembly 50 is disposed in the liquid storage chamber 13 and has an atomization channel 21 formed inside the airway assembly 50. The atomization channel 21 is connected to the air outlet 14 and the air inlet 15. The atomizing core 3 is disposed in the atomization channel 21. The atomizing core 3 can atomize the atomized liquid to form an aerosol. The atomized aerosol of the atomizing core 3 can be released into the atomization channel 21. The airway assembly 50 is provided with a liquid inlet 22 that connects to the liquid storage chamber 13. The atomized liquid in the liquid storage chamber 13 can be transferred to the atomizing core 3 through the liquid inlet 22. The isolation component 40 is used to fit into the atomization channel 21. By filling and sealing the atomization channel 21 with the isolation component 40, the atomizing liquid is isolated from the outside air, preventing the atomizing liquid from contacting the outside air before the atomizer is used, and effectively preventing the atomizing liquid from oxidizing and deteriorating due to long-term contact with air. It should be noted that "before the atomizer is used" includes, but is not limited to, situations or occasions during the transportation, storage, or carrying of the atomizer.

[0093] Please refer to further details. Figure 1 Before activating the atomizer, simply insert the isolation component 40 into the atomization channel 21 through the air outlet 14. The isolation component 40 fills the atomization channel 21, preventing the accumulation of atomized liquid within it, and seals the atomization channel 21, effectively preventing leakage of the atomized liquid. Please refer to further details. Figure 2 When the atomizer is needed, simply remove the isolation component 40 from the atomization channel 21. The isolation component 40 will then open the atomization channel 21. Under the negative pressure created by the user's inhalation, external air can be introduced into the atomization channel 21 through the air inlet 15. The aerosol in the atomization channel 21 is first mixed with the air introduced into the atomization channel 21, and then introduced into the air outlet 14 along with the airflow. Finally, it flows out into the user's mouth through the air outlet 14.

[0094] The atomizer provided in this embodiment of the invention, compared with the prior art, features a liquid storage chamber 13 inside the atomizing cartridge body 1, an airway assembly 50 with an atomization channel 21 inside the liquid storage chamber 13, and an atomizing core 3 installed inside the atomization channel 21. Before the atomizer is activated, the isolation assembly 40 is simply placed into the atomization channel 21 through the air outlet 14. The isolation assembly 40 fills and seals the atomization channel 21, isolating the atomized liquid from the outside air. This prevents the atomized liquid from contacting the outside air before the atomizer is activated, effectively preventing oxidation and deterioration of the atomized liquid due to long-term contact with air. Simultaneously, it avoids the poor structural reliability of the liquid-core separation structure, which could lead to liquid-core separation failure. Furthermore, it effectively prevents leakage of the atomized liquid through the atomization channel 21, thus preventing pollution and waste. When the atomizer is needed, simply remove the isolation component 40 from the atomization channel 21 to easily and quickly open the atomization channel 21. The atomizing liquid in the liquid storage chamber 13 can be quickly and timely transferred to the atomizing core 3 in the atomization channel 21 through the infusion port 22, without having to wait a long time for the atomizing liquid to soak the atomizing core 3 to prevent the atomizing core 3 from burning dry.

[0095] Please refer to further details. Figure 1 , Figure 2 and Figure 6 In some embodiments, a through channel 33 is formed inside the atomizing core 3, extending axially along the atomizing channel 21. An isolation component 40 is inserted into the air outlet 14, the atomizing channel 21, and the through channel 33. In this embodiment, a through channel 33 is formed inside the atomizing core 3 for the isolation component 40 to pass through. Before the atomizer is activated, the isolation component 40 is simply inserted through the air outlet 14 into the air outlet 14, the atomizing channel 21, and the through channel 33. This allows the isolation component 40 to fill and seal the atomizing channel 21, isolating the atomized liquid from the outside air and preventing leakage. When the atomizer needs to be used, the isolation component 40 is simply removed. The atomized liquid in the reservoir 13 can be quickly and promptly transferred to the atomizing core 3 in the atomizing channel 21 via the infusion port 22, eliminating the need for a long waiting period for the atomizing liquid to soak into the atomizing core 3 and prevent dry burning.

[0096] Please refer to further details. Figure 1 , Figure 3 and Figure 6In some embodiments, the isolation assembly 40 includes a first isolation member 4 for inserting into and filling the atomizing channel 21 and a second sealing member 6 sleeved on the first isolation member 4 and located above the atomizing core 3. The second sealing member 6 abuts against the inner wall of the atomizing channel 21. In this embodiment, the isolation assembly 40 includes a first isolation member 4 and a second sealing member 6 sleeved on the first isolation member 4. The second sealing member 6 is located above the atomizing core 3. When the isolation assembly 40 is inserted into the atomizing channel 21, the second sealing member 6 abuts against the inner wall of the atomizing channel 21, enhancing the sealing between the isolation assembly 40 and the atomizing channel 21. Furthermore, during the insertion or removal of the isolation assembly 40, the second sealing member 6 slides against the inner wall of the atomizing channel 21 due to its contact with the inner wall, which helps improve the reliability of inserting or removing the isolation assembly 40. It should be noted that in some specific application scenarios, the second sealing member 6 can be a sealing ring made of silicone or rubber, or a sealing sleeve made of silicone or rubber. It should be noted that the first isolation element 4 can be, but is not limited to, a silicone rod, a plastic rod, a metal rod, or a rubber rod.

[0097] Please refer to further details. Figure 1 , Figure 2 and Figure 3 In some embodiments, the atomizing seat assembly 12 of the atomizing bullet body 1 further includes a first sealing member 122 disposed below the air passage assembly 50. The first sealing member 122 is provided with a positioning hole 16 connecting the atomizing channel 21 and the air inlet 15. The end of the isolation component 40 facing away from the air outlet 14 is inserted into the positioning hole 16. In this embodiment, the first sealing member 122 is disposed below the air passage assembly 50, and the first sealing member 122 is provided with a positioning hole 16. The positioning hole 16 connects the atomizing channel 21 and the air inlet 15. When the isolation component 40 is inserted into the atomizing channel 21, the end of the isolation component 40 facing away from the air outlet 14 is inserted into the positioning hole 16. The positioning hole 16 and the corresponding end of the isolation component 40 achieve an interference fit, which can play a good sealing role, thereby effectively isolating the atomized liquid from the outside air and preventing the atomized liquid from leaking through the atomizing channel 21. Furthermore, the end of the isolation component 40 facing away from the air outlet 14 is inserted into the positioning hole 16, which can fix the isolation component 40 under the action of friction, preventing the isolation component 40 from loosening and falling off, thus affecting the sealing performance of the atomizing channel 21. It should be noted that in some specific application scenarios, the first sealing element 122 can be a silicone seat or a rubber seat, and the first sealing element 122 supports and fixes itself to the base 121 of the atomizing bullet body 1.

[0098] Please refer to further details. Figure 1 , Figure 2 and Figure 7In some embodiments, the airway assembly 50 includes a suction tube 8 connected to the shell 11 of the atomizing cartridge body 1 and a limiting member 2 connected to the suction tube 8. The limiting member 2 is a limiting tube that fits around the atomizing core 3 to limit its position. The limiting tube has a liquid inlet 22. The pipe of the suction tube 8 and the pipe of the limiting tube together form an atomizing channel 21. The atomizing core 3 is disposed in the atomizing channel 21. The first sealing member 122 is provided with a positioning groove 19 communicating with the positioning hole 16. The end of the limiting tube facing away from the suction tube 8 is inserted and positioned in the positioning groove 19. In this embodiment, by providing a positioning groove 19 communicating with the positioning hole 16 on the first sealing member 122, the limiting tube can be securely installed in the liquid storage tank 13 simply by inserting and positioning the end of the limiting tube facing away from the suction tube 8 in the positioning groove 19.

[0099] Please refer to further details. Figure 1 , Figure 2 and Figure 6 In some embodiments, the airway assembly 50 further includes a third seal 9, which is disposed at the connection between the suction tube 8 and the limiting tube to enhance the sealing at the connection and prevent leakage from the assembly gap between the suction tube 8 and the limiting tube. It should be noted that in some specific applications, the third seal 9 can be a sealing ring made of silicone or rubber, or a sealing sleeve made of silicone or rubber.

[0100] Please refer to the following: Figures 1 to 7 The atomizer provided in the embodiments of the present invention will now be described. The atomizer provided in the embodiments of the present invention is applicable to aerosol generating devices. The aerosol generating device mentioned in the embodiments of the present invention generally includes an atomizer and a power supply device 10 electrically connected to the atomizer. When using the aerosol generating device, the power supply device 10 can provide electrical energy to the atomizer. Under the action of electric drive, the atomizing core of the atomizer atomizes the atomizing liquid stored in the atomizer to form an aerosol that can be inhaled by the user.

[0101] Please refer to further details. Figure 1 , Figure 2 and Figure 5The atomizer provided in this embodiment of the invention includes an atomizing bullet body 1, an atomizing core 3, and an isolation component 40. The atomizing bullet body 1 has a cylindrical outer contour and a liquid storage chamber 13 for storing atomized liquid is formed inside the atomizing bullet body 1. The atomizing bullet body 1 is provided with an air outlet 14 and an air inlet 15. An air passage component 50 is disposed in the liquid storage chamber 13, and an atomization channel 21 is formed inside the air passage component 50. The atomization channel 21 is connected to the air outlet 14 and the air inlet 15. The atomizing core 3 is disposed in the atomization channel 21. The atomizing core 3 can atomize the atomized liquid to form an aerosol, and the atomized aerosol of the atomizing core 3 can be released into the atomization channel 21. The atomizing core 3 is electrically connected to the positive terminal of the power supply device 10 through a first electrical connection unit 35, and the atomizing core 3 is electrically connected to the negative terminal of the power supply device 10 through a second electrical connection unit 36. The isolation component 40 is used to fit into the atomization channel 21, and the isolation component 40 can be electrically connected to the power supply unit 10 of the aerosol generator in parallel with the atomizing core 3. When the isolation component 40 is inserted into the atomization channel 21, the isolation component 40 can electrically connect the first electrical connection unit 35 and the second electrical connection unit 36. At this time, the isolation component 40 and the atomizing core 3 are electrically connected to the power supply unit 10 of the aerosol generator in parallel, so that the circuit formed by the atomizing core 3 and the power supply unit 10 is in a short-circuit state. Specifically, in actual implementation, by placing the isolation component 40 in the atomization channel 21, the liquid storage chamber 13 can be kept in a closed state, which can prevent the aerosol generator from malfunctioning due to external factors during transportation. However, due to the possibility of insufficient sealing between the isolation component 40 and the atomization channel 21, and because the second isolation member 5 located in the lower half of the isolation component 40 is conductive, the circuit of the isolation component 40 will be in a conductive state, and the circuit formed by the atomizing core 3 and the power supply device 10 will be in a short-circuit state. In other words, this will cause the atomizing core 3 connected in parallel to it to be in a short-circuit state. When the control board detects the short-circuit state, it will shut off the power output from the power supply device 10 to the atomizing core, preventing the atomizer from starting atomization. This overcomes the defect that the atomizer is prone to false start-up due to factors such as air pressure changes, collisions, squeezing, and misoperation before use, effectively preventing false start-up of the atomizer due to factors such as air pressure changes, collisions, squeezing, and misoperation before use, and improving the safety of the aerosol generation device.

[0102] The atomizer provided in this embodiment of the invention, compared with the prior art, provides an atomization channel 21 inside the atomizing cartridge body 1, installs an atomizing core 3 inside the atomization channel 21, and electrically connects the atomizing core 3 to the positive terminal of the power supply device 10 through a first electrical connection unit 35, and electrically connects the atomizing core 3 to the negative terminal of the power supply device 10 through a second electrical connection unit 36. Before the atomizer is activated, only the isolation component 40 needs to be placed in the atomization channel 21, and the first electrical connection unit 35 and the second electrical connection unit 36 ​​are electrically connected using the isolation component 40. At this time, the isolation component 40 and the atomizing core 3 are electrically connected to the power supply device 10 of the aerosol generator in parallel, which can make the circuit formed by the atomizing core 3 and the power supply device 10 short-circuited. At this time, the power supply device 10 can stop supplying power to the atomizing core 3, so that the atomizer cannot start atomizing work. This overcomes the defect that the atomizer is prone to accidental start-up due to factors such as air pressure changes, collisions, squeezing, and misoperation before it is put into use. This effectively prevents the atomizer from accidental start-up before it is put into use and thus prevents safety accidents caused by accidental start-up. It is beneficial to improve the safety of the aerosol generating device.

[0103] Please refer to further details. Figure 1 , Figure 4 and Figure 5 In some embodiments, the isolation component 40 includes a first isolation member 4 and a second isolation member 5, which are connected. When the first isolation member 4 is inserted into and fills the atomization channel 21, it fills and seals the atomization channel 21, isolating the atomized liquid from the outside air. This prevents the atomized liquid from contacting the outside air before the atomizer is activated, effectively preventing oxidation and deterioration due to prolonged contact with air. It also effectively prevents leakage of the atomized liquid through the atomization channel 21, thus preventing pollution and waste. Furthermore, the first isolation member 4, used to insert into and fill the atomization channel 21, also keeps the liquid storage chamber 13 in a closed state, preventing the atomization device from malfunctioning due to external factors during transportation. Simultaneously with the insertion and filling of the atomization channel 21 by the first isolation member 4, the second isolation member 5 electrically connects the first electrical connection unit 35 and the second electrical connection unit 36, short-circuiting the circuit formed by the atomizing core 3 and the power supply device 10, preventing accidental activation of the atomizer before activation and potential safety accidents. When the atomizer needs to be activated, simply pull the first isolator 4 out of the atomization channel 21. The first isolator 4 will cause the second isolator 5 to disengage from the first electrical connection unit 35 and the second electrical connection unit 36, which will allow the atomization channel 21 to be opened quickly and easily. The atomizing liquid in the liquid storage chamber 13 can be quickly and timely transferred to the atomizing core 3 in the atomization channel 21 through the liquid inlet 22. The circuit formed by the atomizing core 3 and the power supply device 10 is in a closed state, and the power supply device 10 can supply power to the atomizing core 3 so that the atomizer can start atomization.

[0104] Please refer to further details. Figure 1 , Figure 4 and Figure 5 In some other embodiments, the isolation component 40 includes a first isolation member 4, a second isolation member 5, and a push-pull member 7. The first isolation member 4 is used to insert into and fill the atomization channel 21. The second isolation member 5 is used to electrically connect the first electrical connection unit 35 and the second electrical connection unit 36. The push-pull member 7 is used to move the first isolation member 4 into or out of the atomization channel 21. The first end of the first isolation member 4 is connected to the second isolation member 5, and the second end of the first isolation member 4 is connected to the push-pull member 7. In this embodiment, the user can operate the first isolation member 4 and the second isolation member 5 of the isolation component 40 through the push-pull member 7 to easily insert or remove the isolation component 40. It should be noted that the second isolation member 5 can be, but is not limited to, a conductive metal part such as a copper rod, aluminum rod, or iron rod.

[0105] Please refer to further details. Figure 1 , Figure 4 and Figure 5 In some other embodiments, the isolation component 40 includes a second isolation member 5 and a push-pull member 7. The push-pull member 7 is connected to the second isolation member 5. The second isolation member 5 is used to electrically connect the first electrical connection unit 35 and the second electrical connection unit 36. The push-pull member 7 is used to move the second isolation member 5 into or out of the atomization channel 21. In this embodiment, the first isolation member 4 can be omitted. By providing a second isolation member 5 that can be inserted into the atomization channel 21, the second isolation member 5 can both fill and seal the atomization channel 21 to isolate the atomized liquid from the outside air, and the second isolation member 5 can also electrically connect the first electrical connection unit 35 and the second electrical connection unit 36. The user can directly move the second isolation member 5 into or out of the atomization channel 21 using the push-pull member 7.

[0106] Please refer to further details. Figure 1 , Figure 4 and Figure 5In some embodiments, the isolation assembly 40 further includes a second sealing member 6 sleeved on the first isolation member 4 and located above the atomizing core 3. The second sealing member 6 abuts against the inner wall of the atomizing channel 21. A first sealing member 122 is provided inside the atomizing cartridge body 1 and below the atomizing core 3. The first sealing member 122 has a positioning hole 16 connecting the atomizing channel 21 and the air inlet 15. One end of the second isolation member 5 facing away from the first isolation member 4 is inserted into the positioning hole 16. In this embodiment, the second sealing member 6 is located above the atomizing core 3. When the first isolation member 4 is inserted into the atomizing channel 21, the second sealing member 6 abuts against the inner wall of the atomizing channel 21, enhancing the sealing between the first isolation member 4 and the atomizing channel 21. Furthermore, the first sealing member 122 located below the atomizing core 3 is provided with a positioning hole 16, which connects the atomizing channel 21 and the air inlet 15. When the second isolator 5 is inserted into the atomizing channel 21, the end of the second isolator 5 facing away from the first isolator 4 is inserted into the positioning hole 16. The positioning hole 16 and the corresponding end of the second isolator 5 achieve an interference fit, which can play a good sealing role, thereby effectively isolating the atomized liquid from the outside air and preventing the atomized liquid from leaking through the atomizing channel 21. In addition, the end of the second isolator 5 facing away from the first isolator 4 is inserted into the positioning hole 16, which can fix the second isolator 5 under the action of friction, preventing the second isolator 5 from loosening and falling off, thus affecting the stability of the contact between the second isolator 5 and the first electrical connection unit 35 and / or the second electrical connection unit 36. It should be noted that in some specific application scenarios, the second sealing member 6 can be a sealing ring made of silicone or rubber, or a sealing sleeve made of silicone or rubber. The first isolation element 4 may be, but is not limited to, a silicone rod, a plastic rod, a metal rod, or a rubber rod. The first sealing element 122 may be a silicone seat or a rubber seat. The first sealing element 122 is supported and fixed on the base 121 of the atomizing bullet body 1.

[0107] Understandably, in some embodiments, the isolation assembly 40 also includes a control board electrically connected to the atomizing core 3 and / or the power supply unit 10. The control board can detect when the atomizing core 3 is in a short-circuit state to control the atomizing device to stop supplying power to the atomizing core 3, preventing power loss in the power supply unit 10 before the atomizer is used. It should be noted that the control board may be equipped with a detection circuit for detecting when the atomizing core 3 is in a short-circuit state and a switching circuit for controlling the atomizing device to stop or start supplying power to the atomizing core 3 based on the signal detected by the detection circuit.

[0108] Please refer to further details. Figure 5 In some embodiments, the first electrical connection unit 35 and / or the second electrical connection unit 36 ​​may be, but is not limited to, conductive contacts, pins and / or electrodes made of conductive metal material, and the conductive contacts, pins and / or electrodes are electrically connected to the heating element 31 of the atomizing core 3.

[0109] Please refer to further details. Figure 1 , Figure 2 and Figure 6 In some embodiments, the atomizing core 3 has a through channel 33 extending axially along the atomizing channel 21, and the second isolator 5 of the isolation assembly 40 is inserted into the through channel 33. In this embodiment, the atomizing core 3 has a through channel 33 through which the isolation assembly 40 passes. Before the atomizer is activated, the second isolator 5 of the isolation assembly 40 is simply inserted into the through channel 33 through the air outlet 14. The first electrical connection unit 35 and the second electrical connection unit 36 ​​are electrically connected through the second isolator 5, which can keep the circuit formed by the atomizing core 3 and the power supply device 10 in a short-circuit state, preventing the atomizer from being accidentally started before activation and causing a safety accident. Since the second isolator 5 is inserted into the through channel 33, it can play a positioning role, preventing the second isolator 5 from being misaligned and affecting the stability of the contact between the second isolator 5 and the first electrical connection unit 35 and / or the second electrical connection unit 36.

[0110] Please refer to further details. Figure 1 , Figure 2 and Figure 3 In some embodiments, the atomizer further includes an airway assembly 50 disposed within a liquid storage chamber 13. The airway assembly 50 has an atomization channel 21 formed inside it, and a liquid inlet 22 communicating with the liquid storage chamber 13 is provided on the airway assembly 50. The atomized liquid in the liquid storage chamber 13 can be transferred to the atomizing core 3 via the liquid inlet 22. The atomizing cartridge body 1 includes a shell 11 and a base 121 disposed on the end opening of the shell 11. An air outlet 14 is provided at the top of the shell 11, and an air inlet 15 is provided on the base 121. The airway assembly 50 is disposed within the shell 11, with its top end connected to the shell 11 and its bottom end connected to the base 121. The portion of the shell 11 outside the airway assembly 50 defines the liquid storage chamber 13. When using the atomizer, the user inhales through the air outlet 14. Under the negative pressure created by the user's inhalation, external air is introduced into the atomization channel 21 through the air inlet 15. The aerosol in the atomization channel 21 is carried to the air outlet 14 by the suction airflow and finally enters the user's mouth and is inhaled by the user.

[0111] Please refer to further details. Figure 1 , Figure 2 and Figure 3In some embodiments, the atomizing seat assembly 12 of the atomizing cartridge body 1 further includes a first sealing member 122 disposed below the airway assembly 50. The first sealing member 122 is provided with a positioning hole 16 for fitting onto the first end of the isolation assembly 40. The positioning hole 16 connects the atomizing channel 21 and the air inlet 15. The diameter of the positioning hole 16 is less than or equal to the diameter of the through channel 33 on the atomizing core 3. In this embodiment, the air introduced by the air inlet 15 can be concentrated and guided into the through channel 33 of the atomizing core 3 under the action of the positioning hole 16, so that the airflow can fully and quickly remove the aerosol inside the through channel 33, which is beneficial to improving the atomization efficiency.
