Description

Technical Field

[0001] The present application relates to the field of atomization technology, and in particular to an atomization component and an electronic atomizer. Background Art

[0002] An aerosol is a colloidal dispersion system composed of small solid or liquid particles dispersed and suspended in a gaseous medium. Because aerosols can be absorbed through the respiratory system, they offer users a novel alternative absorption method. An atomizer is a device that converts a stored atomizable medium into an aerosol through heating or ultrasound. Atomizable media include liquids, gels, pastes, or solid aerosol-forming matrices. Atomizing these media delivers an inhalable aerosol to the user, replacing conventional product forms and absorption methods.

[0003] Because atomizers operate at varying ambient temperatures, the volume of air inside their liquid reservoirs fluctuates with temperature, causing changes in the air pressure within the reservoir. As the ambient temperature rises, the volume and pressure of the air inside the reservoir increase, disrupting the force balance between the reservoir and the atomizer core. This causes the atomized liquid to overflow the reservoir under pressure, resulting in leakage, which in turn affects the user experience of the atomizer. Summary of the Invention

[0044] An embodiment of the present application provides an electronic atomizer 1000 for heating and atomizing an atomizing liquid to generate an aerosol for use by a user. The aerosol-generating substrate includes, but is not limited to, materials used for medical, health, wellness, and beauty purposes.

[0045] like Figure 1 and Figure 2 As shown, the electronic atomizer 1000 provided in the embodiment of the present application includes an atomizer assembly 100 and a battery assembly 200. The battery assembly 200 is electrically connected to the atomizer assembly 100 to provide electrical energy to the atomizer assembly 100. The atomizer assembly 100 is used to store atomized liquid and heat the atomized liquid under the action of the electrical energy of the battery assembly 200 to generate an aerosol for the user to take.

[0046] In this embodiment, the atomizer assembly 100 includes an atomizer core 40 and a receiving chamber 27 (eg, Figure 3 As shown), the atomizer assembly 100 and the battery assembly 200 are detachably connected. As an independent component, the atomizer assembly 100 can be replaced with a new atomizer assembly 100 after the atomizer medium in the accommodating chamber 27 is used up. In other embodiments, the atomizer assembly 100 and the battery assembly 200 can also be fixedly connected, and the atomizer assembly 100 and the battery assembly 200 are not detachable. Alternatively, the atomizer core 40 of the atomizer assembly 100 can also be fixed to the battery assembly 200, and the part of the atomizer assembly 100 with the accommodating chamber 27 can be detachable to replace the atomizer medium in the accommodating chamber 27 after use, and the atomizer core 40 can be not disassembled together with the part with the accommodating chamber 27 to reduce the user's usage cost.

[0047] As described in the background, existing electronic atomizers 1000 commonly experience leakage. Specifically, when the electronic atomizer 1000 is used at different ambient temperatures, the volume of air within its chamber 27 varies with the temperature. As the ambient temperature rises, the volume and pressure of the air within the chamber 27 increase, squeezing the atomized liquid. Once the air exceeds the liquid-locking capacity of the atomizer core 40 and the ventilation channel, leakage occurs.

[0048] Moreover, as the capacity of the accommodating chamber 27 becomes larger and larger, the volume of the cavity of the accommodating chamber 27 in the later stage of use also becomes larger and larger, so the situation of squeeze leakage becomes more serious. In response to the above problems, the existing anti-leakage technology usually reduces the risk of leakage by designing the ventilation channel and the liquid storage structure, but this method does not effectively improve the leakage phenomenon of the electronic atomizer 1000 with a large injection volume. Taking the electronic atomizer 1000 with a capacity of 10ml as an example, its full-cycle leakage volume can reach 25%-30%, which seriously affects the performance, life and user experience of the electronic atomizer 1000.

[0049] For leakage issues with large-volume electronic atomizers 1000, please refer to Figures 2 to 5 The atomization assembly 100 of the electronic atomizer 1000 of the present application includes a main shell 20 , an atomization core 40 and at least one flexible liquid capsule 60 .

[0050] The main housing 20 has a accommodating chamber 27. A flexible liquid bladder 60 is disposed within the accommodating chamber 27, dividing the accommodating chamber into a liquid storage space 272 and at least one buffer space 274. The main housing 20 is provided with a vent 214 connecting the buffer space 274 with the outside atmosphere, and a ventilation groove 216 connecting the liquid storage space 272 with the outside atmosphere. The liquid storage space 272 is connected to the outside atmosphere via the ventilation groove 216 to maintain the pressure within the liquid storage space 272 as the atomized liquid is consumed. The atomizer core 40 is mounted at one end of the main housing 20 and connected to the liquid storage space 272. Atomized liquid is stored in the liquid storage space 272 and then enters the atomizer core 40 for atomization. The flexible liquid bladder 60 is capable of elastically deforming in response to changes in the pressure difference between the liquid storage space 272 and the outside atmosphere to adjust the volume of the liquid storage space 272.

[0051] In this way, the flexible liquid capsule 60 of the atomizer assembly 100 in the present application can automatically undergo elastic deformation following the change in the pressure difference between the liquid storage space 272 and the external atmosphere, thereby maintaining the pressure in the liquid storage space 272 stable, effectively reducing or even eliminating leakage, and improving the user experience of the electronic atomizer 1000.

[0052] It can be understood that the number and location of the flexible liquid capsules 60 are not limited, and different numbers of flexible liquid capsules 60 can be placed at different locations of the accommodating cavity 27 as needed. Figure 7 As shown, in some embodiments, the flexible liquid capsule 60 and the atomizing core 40 are respectively disposed at opposite ends of the main housing 20. Figure 8As shown, in other embodiments, the atomizer assembly 100 includes two groups of flexible liquid capsules 60, each group includes at least one flexible liquid capsule 60, and the two groups of flexible liquid capsules 60 are respectively disposed on opposite sides of the main housing 20, and the atomizer core 40 is located between the two groups of flexible liquid capsules 60. Specifically, in one embodiment, the atomizer assembly 100 includes two groups of flexible liquid capsules 60, each group includes only one flexible liquid capsule 60, and the two flexible liquid capsules 60 are respectively disposed on opposite sides of the main housing 20.

[0053] Thus, when the atomized liquid in the liquid storage space 272 changes from the initial state (such as Figure 8 as shown) to nearly complete consumption (as shown Figure 9 As shown in FIG, the flexible liquid capsule 60 is deformed and enlarged under the action of the internal and external pressure difference, and occupies a certain volume of the liquid storage space 272, reducing the drop value of the negative pressure in the liquid storage space 272, thereby avoiding the phenomenon of difficulty in liquid supply and effectively ensuring the stability of liquid supply. Specifically in one embodiment, as shown in FIG. Figure 8 As shown, the initial pressure in the liquid storage space 272 is -200 Pa. Figure 9 As shown, when the atomized liquid is nearly consumed, the pressure in the liquid storage space 272 is -400 Pa, which is only reduced by 200 Pa, due to the deformation of the flexible liquid capsule 60.

[0054] When the ambient temperature increases, Figure 10 As shown, the gas in liquid storage space 272 expands, increasing its volume and pressure. The flexible bladder 60 can reduce its deformation under the influence of the internal and external pressure differential, buffering some or all of the expansion of liquid storage space 272, thereby maintaining a negative pressure level within liquid storage space 272. This effectively relieves the pressure increase caused by temperature rise and reduces leakage of atomized liquid. Specifically, in one embodiment, the initial pressure within liquid storage space 272 is -200 Pa. When the ambient temperature increases, the deformation of the flexible bladder 60 causes the pressure within liquid storage space 272 to rise to -100 Pa, while still maintaining a negative pressure level.

[0055] Preferably, by appropriately reducing the initial negative pressure in the liquid storage space 272, the negative pressure in the liquid storage space 272 can be maintained at a low level during the temperature rise process, thereby more effectively reducing or even preventing leakage of the atomized liquid. Specifically, in one embodiment, if the initial pressure in the liquid storage space 272 is -400 Pa to -500 Pa, as the ambient temperature increases, the pressure in the liquid storage space 272 can be maintained below -200 Pa due to the deformation of the flexible liquid bladder 60.

[0056] As a preferred embodiment, the two sets of flexible liquid capsules 60 are symmetrically arranged, and the symmetry axes of the two sets of flexible liquid capsules 60 extend along the first direction. In this way, when the electronic atomizer 1000 is used in various scenarios such as rotation, sideways, and inversion, the flexible liquid capsules 60 can effectively play a role in stabilizing pressure.

[0057] like Figure 11 As shown, when the atomizer assembly 100 is placed on its side, the flexible liquid capsule 60 on one side is affected by the gravity and pressure of the liquid, its deformation ability is limited, and the deformation amount is reduced. At this time, the flexible liquid capsule 60 on the other side can automatically increase the deformation amount under the action of the internal and external pressure difference, thereby maintaining the negative pressure in the liquid storage space 272 close to or consistent with that when the atomizer assembly 100 is in the upright state.

[0058] like Figure 12 As shown, when the atomizer assembly 100 is inverted, the atomized liquid is retained in the liquid storage space 272 away from one end of the atomizer core 40, and the air cavity in the liquid storage space 272 is connected to the atomizer core 40. Since the flexible liquid capsule 60 is symmetrically arranged, its deformation position in the first direction is interchanged, and the deformation amount remains unchanged, so the negative pressure in the liquid storage space 272 is still close to or consistent with that in the upright state of the atomizer assembly 100. It can be seen that in various placement states, the flexible liquid capsules 60 on both sides of the liquid storage space 272 can automatically adapt to adjust their own deformation, thereby ensuring that the negative pressure in the liquid storage space 272 remains consistent. Furthermore, when the temperature changes in various placement states, the flexible liquid capsule 60 can effectively play a role, reducing or avoiding leakage of the atomized liquid in the liquid storage space 272.

[0059] The following describes the specific structure of the atomizer assembly 100, taking the example of an atomizer assembly 100 including two flexible liquid capsules 60, which are symmetrically arranged on opposite sides of the main housing 20. It is understood that when the atomizer assembly 100 includes only one or more flexible liquid capsules 60, the specific structure of the atomizer assembly 100 can be adaptively adjusted to meet the needs of disposing one or more flexible liquid capsules 60.

[0060] Please refer again Figures 2 to 5The main housing 20 includes an outer shell 21, a base 23, and a bottom cover 25. The outer shell 21 is a hollow shell structure with one end open. The bottom cover 25 is connected to the open end of the outer shell 21. The base 23 is accommodated in the end of the outer shell 21 near the bottom cover 25. The other end of the outer shell 21 is provided with an exhaust pipe 212 and a circumferentially surrounding accommodating cavity 27. One end of the exhaust pipe 212 is connected to the base 23, and the other end of the exhaust pipe 212 extends along a first direction to the closed end of the outer shell 21. An exhaust channel 2121 is formed in the exhaust pipe 212, connecting the base 23 with the external atmosphere. The atomizer core 40 is accommodated in the base 23, and the base 23 is provided with a liquid lowering channel 232 connecting the accommodating cavity 27 and the atomizer core 40. The accommodating chamber 27 is used to store atomized liquid. The atomized liquid in the accommodating chamber 27 can flow into the atomizer core 40 through the lower liquid channel 232, where it is heated and atomized by the atomizer core 40. The aerosol produced by atomization can flow out of the housing 21 through the exhaust channel 2121 for user use. The battery assembly 200 is connected to the end of the atomizer assembly 100 where the atomizer core 40 is located. The battery assembly 200 is electrically connected to the atomizer core 40 to provide power to the atomizer core 40.

[0061] The atomizer core 40 has a cubic structure and can be formed of a high-temperature resistant porous material such as porous glass, porous ceramics or honeycomb ceramics. The surface of the atomizer core 40 facing the accommodating chamber 27 forms a liquid inlet surface, and the surface of the atomizer core 40 facing away from the accommodating chamber 27 is covered with a metal material or an alloy material, wherein the alloy material can be selected from iron-chromium alloy, iron-chromium-aluminum alloy, iron-chromium-nickel alloy, chromium-nickel alloy, titanium alloy, stainless steel alloy, etc. The above-mentioned alloy material is formed on one side of the atomizer core 40 by mold stamping, casting, mechanical weaving, chemical etching or screen printing to form a heating surface.

[0062] In the following embodiments, the height direction of the housing 21 is defined as the first direction (i.e. Figure 2 The length direction of the housing 21 is the second direction (i.e. Figure 2 The width direction of the housing 21 is defined as the third direction (i.e. Figure 2 The first direction, the second direction, and the third direction intersect each other. In a preferred embodiment, the first direction, the second direction, and the third direction are perpendicular to each other. The exhaust pipe 212 of the housing 21 extends along the first direction.

[0063] Two flexible liquid sacs 60 are disposed on opposite sides of the accommodating chamber 27 in the third direction. The edge of each flexible liquid sac 60 is fixed to the wall of the accommodating chamber 27. The flexible liquid sac 60 can be fixed in any manner, such as by snap-fit ​​connection, bonding, etc., thereby dividing the accommodating chamber 27 into a central liquid storage space 272 and two side buffer spaces 274. The atomized liquid is entirely stored in the liquid storage space 272. It will be appreciated that the fixing method of the flexible liquid sac 60 is not limited to this and can be configured as needed to meet different fixing requirements.

[0064] The housing 21 has a plurality of air holes 214 formed on the opposite side walls in the third direction. All of the air holes 214 are spaced apart along the first direction and are located inside the edge of the flexible liquid sac 60. Therefore, the two buffer spaces 274 are connected to the outside atmosphere through the air holes 214, and the air pressure within the buffer spaces 274 is also consistent with the outside atmosphere, while the atomized liquid within the liquid storage space 272 is separated from the outside atmosphere. In a preferred embodiment, the diameter of the air holes 214 is greater than 1 mm. It is understood that the number, size, and arrangement of the air holes 214 are not limited thereto and can be set as needed to meet different requirements.

[0065] Specifically, in some embodiments, the shape of the flexible sac 60 is not limited. The orthographic projection of the flexible sac 60 on the cavity wall can be a regular or irregular shape, such as a square, rectangle, or circle. The flexible sac 60 can be formed from at least one of silicone or polydimethylsiloxane (PDMS). The elastic modulus of the material forming the flexible sac 60 is between 0.5 MPa and 7 MPa, preferably 2.14 MPa, thereby achieving a balance between volume and deformation performance. Conversely, if the elastic modulus of the material forming the flexible sac 60 is too high, effective deformation is difficult to achieve. If the elastic modulus of the material forming the flexible sac 60 is too low, the flexible sac 60 occupies too much space, affecting the size of the liquid storage space 272. It is understood that the shape and material of the flexible sac 60 are not limited to this and can be configured as needed to meet different requirements.

[0066] Furthermore, in some embodiments, the thickness of the flexible bladder 60 is 0.045 mm to 0.5 mm, preferably 0.25 mm, to ensure sufficient strength while allowing for rapid and effective deformation. Conversely, if the thickness of the flexible bladder 60 is too great, it will not be able to deform quickly and effectively, while if the thickness of the flexible bladder 60 is too small, it will be too weak and prone to rupture. It is understood that the thickness of the flexible bladder 60 is not limited to this and can be adjusted as needed to meet different requirements.

[0067] It can be understood that since the flexible liquid sac 60 extending in a plane has greater rigidity and is not easy to deform, as a preferred embodiment, the flexible liquid sac 60 is bent and extended to form a multi-layer folded pleated structure, so that the flexible liquid sac 60 has a larger deformation volume and improves the adjustment ability of the flexible liquid sac 60.

[0068] Specifically in one embodiment, Figure 6 As shown, the flexible bladder 60 bends and extends from the center to the periphery, forming staggered protrusions 61 and depressions 63 arranged from the inside out. The height difference between the protrusions 61 and depressions 63 is 1mm-3mm, the distance between adjacent protrusions 61 is 1mm-5mm, and the distance between adjacent depressions 63 is 1mm-5mm. As a preferred embodiment, the flexible bladder 60 includes at least two protrusions 61 and at least two depressions 63, thereby providing a larger deformation volume. It is understood that the folding method of the flexible bladder 60 is not limited to this and can be configured as needed to meet different deformation requirements.

[0069] The atomizer assembly 100 and the electronic atomizer 1000 equipped therewith, through the provision of the flexible liquid bladder 60, separate the accommodating chamber 27 into a mutually independent liquid storage space 272 and a buffer space 274. The elastic deformation of the flexible liquid bladder 60 effectively maintains the stability of the air pressure in the liquid storage space 272, thereby effectively solving the problem of atomized liquid leakage caused by ambient temperature changes and significantly improving the performance, lifespan, and user experience of the electronic atomizer 1000. This has an excellent anti-leakage effect, especially for large-capacity electronic atomizers 1000.

[0070] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned 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.

[0071] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
