Description

Technical Field

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

[0002] Aerosols are colloidal dispersions 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. For example, electronic atomization devices, which heat liquid or solid aerosol-generating substrates to produce aerosols, are used in various fields to deliver inhalable aerosols to users, replacing conventional product forms and absorption methods.

[0003] Typically, electronic atomization devices atomize an aerosol-generating matrix, which is the material that produces an aerosol after atomization. In side-atomizing atomizers, the heating element can vibrate during transportation or use. Bubbles in the aerosol-generating matrix can move, affecting the liquid supply and causing it to dry out, producing a burnt odor. Utility Model Content

[0004] Based on this, it is necessary to provide an atomizer and an electronic atomization device to address the problem that traditional atomizers are prone to dry burning during side atomization.

DETAILED DESCRIPTION

However, the present application can be implemented in many other ways than those described herein, and those skilled in the art can make similar improvements without violating the scope of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0031] In the description of the present application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of such features. Throughout the description of this application, "plurality" means at least two, for example, two, three, etc., unless otherwise specifically defined.

[0033] In this application, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two elements or interaction between two elements, unless otherwise specified. Those skilled in the art will understand the specific meanings of the above terms in this application based on specific circumstances.

[0034] In this application, unless otherwise expressly specified or limited, when a first feature is "above" or "below" a second feature, it may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium.

[0035] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element.

[0036] In a side-atomizing atomizer, the heater is positioned vertically, with its liquid absorption surface located to the side. An L-shaped lower liquid flow channel is provided within the atomizer to supply liquid. The lower liquid flow channel comprises a vertical flow channel and a corner flow channel intersecting with the vertical flow channel. The corner flow channel directs the vertically flowing aerosol-generating matrix to flow horizontally and contact the liquid absorption surface, thereby supplying liquid to the side-facing liquid absorption surface. However, research has found that after the aerosol-generating matrix flips and shakes, bubbles trapped within the aerosol-generating matrix may migrate to the corner flow channel, where subsequent bubbles can become stuck and unable to float upward, affecting the smoothness of subsequent liquid supply.

[0037] See Figure 1-Figure 2In order to solve this technical problem, the present application provides an atomizer 100. The atomizer 100 includes a housing 10, a bracket 30 and a heating component 50. The housing 10 has an air outlet pipe 12 inside. The bracket 30 is arranged in the housing 10, and a liquid storage chamber 20 is defined between the bracket 30 and the housing 10; the heating component 50 is arranged on the bracket 30, and the heating component 50 includes an atomizing surface 521 and a liquid absorption surface 523. The atomizing surface 521 is not arranged perpendicular to the central axis of the air outlet pipe 12. It can be understood that the atomizing surface 521 of the heating component 50 and the axial non-perpendicular arrangement of the air outlet pipe 12 mean that the atomizing surface 521 and the axis of the air outlet pipe 12 can be parallel, or there is a certain acute angle between the two, for example, the angle formed between them is between 0 and 10 degrees, and it is almost impossible to see with the naked eye that the extension line of the atomizing surface 521 intersects with the axis of the air outlet pipe 12. In this way, the heating element 50 is fixed on the bracket 30 , and the atomizing surface 521 is located on the side intersecting the axial direction of the air outlet pipe 12 , forming the atomizer 100 with side atomization.

[0038] The bracket 30 is provided with a lower liquid channel 31 that communicates with the liquid storage chamber 20, allowing the aerosol-generating substrate to flow directly from the liquid storage chamber 20 into the lower liquid channel 31. The lower liquid channel 31 has a channel sidewall 311 facing the heating element 50. The channel sidewall 311 includes a liquid inlet surface 312 and a sub-sidewall 313 located outside the liquid inlet surface 312. Liquid in the lower liquid channel 31 can flow through the liquid inlet surface 312 to the heating element 50, thereby supplying liquid to the heating element 50.

[0039] Furthermore, the liquid inlet surface 312 remains flush with the sub-sidewall 313, and the liquid inlet surface 312 does not sink relative to the sub-sidewall 313, causing bubbles to become stuck at the liquid inlet surface 312 and affect smooth liquid supply. Furthermore, the liquid inlet surface 312 area is smaller than the area of ​​the liquid aspiration surface 523. It can be understood that the liquid inlet surface area is the effective liquid inlet area on the liquid inlet surface 312, where part of the liquid inlet surface 312 allows liquid to pass through, while another part blocks liquid from passing through. Since the liquid inlet surface area is small, there are no large holes on the liquid inlet surface 312, and bubbles within the aerosol generating matrix will not become stuck at the liquid inlet surface 312. In this way, by preventing the liquid inlet surface 312 from sinking and preventing the liquid inlet surface 312 from accumulating too much, bubbles can be prevented from being stuck at the liquid inlet surface 312 and blocking the aerosol-generating matrix from flowing to the heating component 50, thereby improving the smoothness of liquid supply and preventing the atomizer 100 from dry burning and burning smell.

[0040] Furthermore, a plurality of micropores 321 are formed on the liquid inlet surface 312, connecting the liquid inlet channel with the heating element 50. The combined opening area of ​​all micropores 321 is smaller than the area of ​​the liquid aspiration surface 523, resulting in a smaller effective liquid inlet surface area of ​​the liquid inlet surface 312, thereby preventing bubbles from becoming trapped at the liquid level. Furthermore, the micropores 321 have a very small diameter, which blocks the passage of bubbles from the aerosol generating matrix that migrate to the micropores 321. This allows bubbles in the aerosol generating matrix to smoothly rise to the top along the linear liquid lowering channel 31, preventing bubbles from becoming trapped at the liquid inlet surface 312 and affecting liquid supply.

[0041] Optionally, the diameter of the micropore 321 is 0.4mm-0.8mm, for example, the diameter of the micropore 321 is 0.5mm, and liquid can be supplied through the capillary phenomenon of multiple micropores 321. At the same time, the small diameter of the micropore 321 blocks the entry of bubbles, preventing bubbles from being stuck at the liquid inlet surface 312 and causing poor liquid supply.

[0042] Alternatively, the channel side wall 311 of the lower liquid channel 31 facing the heating component 50 is constructed as a straight side wall, and there is no depression on the channel side wall 311, so bubbles are not easily trapped.

[0043] According to some embodiments of the present application, the heating element 50 includes a heating element 52, which is a non-liquid storage component and does not have the ability to store liquid. The heating element 52 has a liquid absorption surface 523 and an atomizing surface 521. At least one straight-through hole 323 is provided on the heating element 52, which passes through the liquid absorption surface 523 and the atomizing surface 521. In this way, the liquid is guided to flow to the atomizing surface 521 through the straight-through hole 323. When the straight-through hole 323 is provided, a plurality of uniformly arranged straight-through holes 323 can be provided as needed. Compared with the disordered arrangement of holes in the porous structure, by providing a plurality of orderly arranged straight-through holes 323 on the non-liquid storage component, the liquid supply rate can be more effectively controlled and the liquid supply performance can be improved. For example, the heating element is a glass component, and a plurality of orderly arranged straight-through holes 323 are provided on the glass.

[0044] In this case, the heating element 52 does not have the ability to store liquid, and liquid needs to be continuously supplied to the heating element 52 from the lower liquid channel 31 through the liquid inlet surface 312. In the atomizer 100 provided in the present application, the liquid inlet surface 312 is flush with the sub-side wall 313, and micropores 321 are formed on the liquid inlet surface 312. The liquid inlet surface 312 will not be recessed relative to the sub-side wall 313 to prevent bubbles from being stuck, and the micropores 321 will also block the entry of bubbles, thereby preventing bubbles from being stuck at the liquid inlet surface 312 and affecting the liquid supply, thereby ensuring smooth liquid supply to the heating element 52 and preventing the heating element 52 from dry burning.

[0045] According to some embodiments of the present application, the bracket 30 has a partition 32, a lower liquid channel 31 is formed on one side of the partition 32, and a heating component 50 is installed on the other side of the partition 32. In this way, the partition 32 is used to separate the bracket 30 to form the lower liquid channel 31, and the heating component 50 is set on the other side of the partition 32 for atomizing the aerosol to generate the matrix.

[0046] According to some embodiments of the present application, the side of the partition 32 facing the lower liquid channel 31 is at least partially constructed to form a liquid inlet surface 312, and a plurality of micropores 321 are provided on the liquid inlet surface 312 to connect the liquid inlet channel and the heating component 50. In this way, the liquid inlet channel and the heating component 50 are connected by providing the micropores 321 to achieve liquid supply. Specifically, the side of the partition 32 facing the lower liquid channel 31 is a channel sidewall 311, and the channel sidewall 311 includes a liquid inlet surface 312 provided with micropores 321 and a sub-sidewall 313 located on the periphery of the liquid inlet surface 312. The sub-sidewall 313 is flush with the liquid inlet surface 312 to prevent the liquid inlet surface 312 from being recessed relative to the sub-sidewall 313 and bubbles from being trapped at the liquid inlet surface 312. At the same time, the micropores 321 provided on the liquid inlet surface 312 allow liquid to pass through while blocking bubbles from entering the micropores 321, further preventing bubbles from being trapped at the liquid inlet surface 312, thereby ensuring smooth liquid supply.

[0047] For example, the side of the partition 32 facing the lower liquid channel 31 is constructed as a flat surface, and a number of micropores 321 are opened at the position corresponding to the partition 32 and the heating component 50. The area where the micropores 321 are opened is defined as the liquid inlet surface 312, and the other areas are defined as the sub-side wall 313.

[0048] Specifically in some embodiments, the heating component 50 includes a heating element 52, and the heating element 52 has an atomizing surface 521 and a liquid absorption surface 523. The liquid absorption surface 523 is arranged to fit the micropores 321 and the partition 32. In this way, the heating element 52 is fitted to the partition 32, and the liquid flows through the micropores 321 on the partition 32 to the liquid absorption surface 523 of the heating element 52, thereby realizing liquid supply to the heating element 52.

[0049] Optionally, the heating element 52 is a porous structure, such as ceramic, which can store the absorbed aerosol-generating matrix and improve the stability of the liquid supply. Alternatively, the heating element 52 is a non-liquid storage component, such as a glass component. The heating element 52 is provided with at least one through hole 323 that passes through the liquid absorption surface 523 and the atomization surface 521. In this way, the liquid is guided to flow to the atomization surface 521 through the through hole 323. When providing the through hole 323, multiple evenly arranged through holes 323 can be provided as needed. Compared with the disordered arrangement of holes in the porous structure, by providing multiple orderly arranged through holes 323 on the glass, the liquid supply rate can be more effectively controlled and the liquid supply performance can be improved.

[0050] In other embodiments, the heating element 50 includes a heating element 52 and a liquid absorbing member 54. The heating element 52 has an atomizing surface 521 and a liquid absorbing surface 523 opposite the atomizing surface 521. The liquid absorbing surface 523 is located between the liquid absorbing surface 523 and the partition 32, corresponding to the plurality of micropores 321. The aerosol-generating substrate flowing in from the micropores 321 is absorbed, stored, and transferred to the heating element 52 by the liquid absorbing member 54. When the heating element 52 generates heat, it atomizes the aerosol-generating substrate absorbed within it and produces atomized aerosol at the atomizing surface 521. Thus, the liquid absorbing member 54 is provided downstream of the micropores 321 to store the aerosol-generating substrate.

[0051] Optionally, the heating element 52 is a porous structure, such as ceramic, which can store the absorbed aerosol-generating matrix and improve the stability of the liquid supply. Alternatively, the heating element 52 is a non-liquid storage component, such as a glass component. The heating element 52 is provided with at least one through hole 323 that passes through the liquid absorption surface 523 and the atomization surface 521. In this way, the liquid is guided to flow to the atomization surface 521 through the through hole 323. When providing the through hole 323, multiple evenly arranged through holes 323 can be provided as needed. Compared with the disordered arrangement of holes in the porous structure, by providing multiple orderly arranged through holes 323 on the glass, the liquid supply rate can be more effectively controlled and the liquid supply performance can be improved.

[0052] Optionally, the absorbent member 54 is absorbent cotton, and the absorbent member 54 includes but is not limited to ceramic, glass, quartz or fiber, which can store more aerosol generating matrix, continuously provide a certain amount of aerosol generating matrix for the heating element 52, and prevent the heating element 52 from dry burning.

[0053] See Figure 3-Figure 4 According to other embodiments of the present application, the heating component 50 at least partially passes through the partition 32 and faces the lower liquid channel 31. The portion of the heating component 50 facing the lower liquid channel 31 is constructed as a liquid inlet surface 312. In this way, the heating component 50 is at least partially arranged through the partition 32, so that the heating component 50 at least partially contacts the aerosol-generating matrix in the lower liquid channel 31 to supply liquid. The surface of the heating component 50 facing the lower liquid channel 31 is equivalent to the liquid inlet surface 312. The side wall of the partition 32 adjacent to the liquid inlet surface 312 is the sub-side wall 313. The liquid inlet surface 312 is flush with the sub-side wall 313. The liquid inlet surface 312 can allow liquid to flow through, and the liquid inlet surface 312 will not be recessed relative to the sub-side wall 313 to trap bubbles, thereby ensuring smooth liquid supply.

[0054] Furthermore, the partition 32 defines at least one through-hole 323 that communicates with the lower liquid channel 31. The heating element 50 at least partially extends into the through-hole 323 and is flush with the side of the partition 32 facing the liquid channel. The side of the heating element 50 flush with the partition 32 is configured as a liquid inlet surface 312. Thus, by defining the through-hole 323 in the partition 32 and filling the through-hole 323 with the heating element 50, the sidewall 311 of the lower liquid channel 31 remains flat, preventing the aerosol-generating substrate in the lower liquid channel 31 from carrying bubbles into the through-hole 323 of the partition 32, thereby preventing bubbles from becoming lodged in the through-hole 323 and affecting liquid supply.

[0055] At the same time, a number of micropores 321 are formed on the surface of the heating component 50 facing the lower liquid channel 31, and it is constructed as a liquid inlet surface 312. The aerosol generating matrix in the lower liquid channel 31 can flow to the atomizing surface 521 through the micropores 321 on the heating component 50, thereby realizing the liquid supply to the atomizing surface 521 and the atomization of the aerosol generating matrix.

[0056] Specifically, in one embodiment, the heating component 50 includes a heating element 52, which has an atomizing surface 521 and a liquid absorbing surface 523. The side of the heating element 52 with the liquid absorbing surface 523 at least partially extends into the through hole 323. The liquid absorbing surface 523 is at least partially flush with the side of the partition 32 facing the liquid passage and is constructed as the liquid inlet surface 312. In this way, the through hole 323 on the partition 32 is filled by the heating element 52, so that the channel side wall 311 of the lower liquid channel 31 remains flat. The aerosol generating matrix in the lower liquid channel 31 is in direct contact with the portion of the heating element 52 extending into the through hole 323 for liquid supply. During the liquid supply process, bubbles in the aerosol generating matrix can float to the top of the liquid storage chamber 20 along the flat channel side wall 311 and will not get stuck at the liquid inlet surface 312, thereby improving the smoothness of liquid supply.

[0057] Optionally, the heating element 52 is a porous structure, such as ceramic, which can store the absorbed aerosol to generate a matrix, thereby improving the stability of the liquid supply. The ceramic at least partially extends into the through hole 323 and the surface facing the lower liquid channel 31 is constructed as a liquid surface. The liquid surface has a porous structure of ceramic, which is equivalent to forming a number of micropores 321 on the liquid surface, and liquid supply is achieved through the micropores 321.

[0058] Alternatively, the heating element 52 is a non-liquid storage element, for example, the heating element 52 is a glass element, and the heating element 52 is provided with at least one through hole 323 that passes through the liquid absorption surface 523 and the atomizing surface 521. In this way, the liquid is guided to flow to the atomizing surface 521 through the through hole 323. When the through hole 323 is provided, a plurality of evenly arranged through holes 323 can be provided as needed. Compared with the disordered arrangement of holes in the porous structure, by providing a plurality of orderly arranged through holes 323 on the glass, the liquid supply rate can be more effectively controlled and the liquid supply performance can be improved. At the same time, the surface of the glass element at least partially extending into the through hole 323 and facing the lower liquid channel 31 is constructed as a liquid surface. The through hole 323 of the glass element is open on the liquid surface, which is equivalent to forming a plurality of micropores 321 on the liquid surface, and liquid supply is achieved through the micropores 321.

[0059] In another embodiment, the heating element 50 includes a heating element 52 and a liquid absorbing member 54. The heating element 52 has an atomizing surface 521 and a liquid absorbing surface 523. The liquid absorbing member 54 is partially positioned between the liquid absorbing surface 523 and the partition 32. Another portion of the liquid absorbing member 54 extends into the through-hole 323 and is flush with the side of the partition 32 facing the liquid flow channel. The side of the liquid absorbing member 54 flush with the partition 32 is configured as the liquid inlet surface 312. In this way, after the aerosol-generating substrate flows from the liquid storage chamber 20 into the lower liquid channel 31, it can directly contact the liquid absorbing member 54 flush with the partition 32, and then flow through the liquid absorbing member 54 to the heating element 52, achieving liquid supply. Simultaneously, at least a portion of the liquid absorbing member 54 extends into the through-hole 323 to fill the through-hole 323, thereby smoothing the channel sidewall 311 of the lower liquid channel 31 and preventing depressions in the channel sidewall 311 that could trap bubbles in the aerosol-generating substrate.

[0060] Optionally, the heating element 52 is a porous structure, such as ceramic, which can store the absorbed aerosol-generating matrix and improve the stability of the liquid supply. Alternatively, the heating element 52 is a non-liquid storage component, such as a glass component. The heating element 52 is provided with at least one through hole 323 that passes through the liquid absorption surface 523 and the atomization surface 521. In this way, the liquid is guided to flow to the atomization surface 521 through the through hole 323. When providing the through hole 323, multiple evenly arranged through holes 323 can be provided as needed. Compared with the disordered arrangement of holes in the porous structure, by providing multiple orderly arranged through holes 323 on the glass, the liquid supply rate can be more effectively controlled and the liquid supply performance can be improved.

[0061] Optionally, the absorbent member 54 is absorbent cotton, and the absorbent member 54 includes but is not limited to ceramic, glass, quartz or fiber, which can store more aerosol generating matrix, continuously provide a certain amount of aerosol generating matrix for the heating element 52, and prevent the heating element 52 from dry burning.

[0062] Furthermore, the liquid absorption part 54 includes a first liquid absorption part 541 and a second liquid absorption part 543 provided on the first liquid absorption part 54. The first liquid absorption part 541 is provided between the partition 32 and the liquid absorption surface 523. The second liquid absorption part 543 fills the through hole 323 and remains flush with the sub-side wall 313 of the side wall facing the lower liquid channel 31, so that the through hole 323 on the partition 32 is filled by the second liquid absorption part 543.

[0063] Furthermore, the orthographic projection of the first liquid absorbing portion 541 toward the second liquid absorbing portion 543 overlaps and extends beyond the second liquid absorbing portion 543, meaning that the first liquid absorbing portion 541 has a larger area. The larger first liquid absorbing portion 541 is installed between the partition 32 and the heating element 52, providing a more stable installation. Furthermore, a groove 325 is defined on the side of the partition 32 facing the liquid absorbing surface 523, which is connected to the through hole 323. The second liquid absorbing portion 543 is positioned within the groove 325, further limiting the installation position of the heating element 50 through the groove 325 on the partition 32, ensuring installation stability.

[0064] According to other embodiments of the present application, the side of the partition 32 facing the lower liquid channel 31 is at least partially constructed to form a liquid inlet surface 312, the heating component 50 at least partially passes through the partition 32 and faces the lower liquid channel 31, and the portion of the heating component 50 facing the lower liquid channel 31 is constructed as the liquid inlet surface 312. In this way, the liquid inlet surface 312 is formed on the partition 32, and the heating component 50 is also at least partially passed through the partition 32 to form a liquid inlet surface 312 on the heating component 50.

[0065] For example, the partition 32 is provided with at least one through-hole 323 communicating with the lower liquid channel 31. The heating element 50 at least partially extends into the through-hole 323 and is flush with the side of the partition 32 facing the liquid channel. The side of the heating element 50 flush with the partition 32 is configured as a liquid inlet surface 312. Simultaneously, a plurality of micropores 321 are provided on the partition 32 surrounding the through-hole 323 to form another liquid inlet surface 312. In this manner, liquid can be supplied not only through the liquid inlet surface 312 where the micropores 321 on the partition 32 are located, but also through the liquid inlet surface 312 formed by the heating element 50 passing through the partition 32, thereby providing a larger liquid supply area. At the same time, the liquid inlet surface 312 on the partition 32 is flush with the sub-side wall 313 on the partition 32, and the liquid inlet surface 312 on the heating component 50 is also flush with the sub-side wall 313. In this way, both liquid inlet surfaces 312 and the sub-partition walls remain flush, forming a flat channel side wall 311, preventing the presence of depressions at the liquid inlet surface 312 that could cause bubbles to get stuck, thereby ensuring smooth liquid inflow. At the same time, the micropores 321 on the liquid inlet surface 312 allow liquid to pass through while blocking bubbles from entering the micropores 321, further preventing bubbles from getting stuck at the liquid inlet surface 312 and further ensuring smooth liquid supply.

[0066] The specific details of the liquid inlet surface 312 on the partition 32, the specific details of the liquid inlet surface 312 on the heating component 50, and the arrangement of the heating component 50 are similar to those in the other embodiments described above and are not described in detail here.

[0067] See Figure 5 According to some embodiments of the present application, the liquid lowering channel 31 has a curved inner wall 314, the axially opposite ends of the curved inner wall 314 are spaced apart from each other, and the channel side wall 311 is connected between the axially opposite ends of the curved inner wall 314. In this way, the liquid lowering channel 31 is formed by enclosing the curved inner wall 314 and the flat channel side wall 311. The entire inner wall of the liquid lowering channel 31 is smooth and smooth, which facilitates the smooth liquid lowering of the aerosol generating matrix.

[0068] According to some embodiments of the present application, the present application further provides an electronic atomization device, comprising a power supply assembly and the atomizer 100 described in any of the above embodiments. The power supply assembly is used to power the atomizer 100. When the atomizer 100 is powered on, it heats the atomized aerosol to generate a matrix. The electronic atomization device using the atomizer 100 described in any of the above embodiments has the same technical effects as the atomizer 100 described above, and is not limited here.

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.
