[0027] An embodiment of the present application discloses an atomizer 3, which is applied to an atomizing device and installed in an atomizing housing 1 of the atomizing device. The shape of the liquid storage cup 34 in the atomizer 3 can be designed according to the space in the atomizing housing 1 for installing the atomizer 3, so that the shape of the liquid storage cup 34 is adapted to the space in the atomizing housing 1 after installing the auxiliary components, in order to make full use of the internal space of the atomizing housing 1, improve the utilization rate of the space in the atomizing housing 1, avoid waste of the space in the atomizing housing 1, and at the same time help to increase the liquid storage capacity of the liquid storage cup 34.

[0028] Please refer to Figures 2 to 6 , the atomizer 3 has an atomizing channel 31 extending in a first direction, and the first direction is the up-down direction when the atomizing device is in use and the air flow is upward. The atomizer 3 includes a liquid storage cup 34, and the liquid storage cup 34 has a liquid storage cavity for storing atomizing liquid. The atomizing channel 31 penetrates through the liquid storage cup 34 and the liquid storage cavity in the first direction.

[0029] In one embodiment, please refer to Figures 2 to 6, the liquid storage cup 34 has openings at both ends in the first direction. Among the two openings, the first opening is located downstream of the second opening in the air flow direction. The atomizer 3 further includes a first seal 32 and a second seal 33. The first seal 32 plugs the first opening, and the second seal 33 plugs the second opening. Through holes are provided on both the first seal 32 and the second seal 33, and the atomization channel 31 is located in the through holes to enable the atomization channel 31 to penetrate through the liquid storage cup 34 and the liquid storage cavity in the first direction.

[0030] In another embodiment, the liquid storage cup 34 only has the first opening. The liquid storage cup 34 has a cup bottom at the other end in the first direction. A perforation corresponding to the through hole on the first seal 32 in the first direction is provided on the cup bottom, and the atomization channel 31 passes through the perforation to enable the atomization channel 31 to penetrate through the liquid storage cup 34 and the liquid storage cavity in the first direction.

[0031] In one embodiment, please continue to refer to Figures 2 to 6 , the liquid storage cup 34 includes a first part 341 and a second part 342 arranged in the first direction. The first part 341 is connected to the second part 342. The second part 342 has a first convex portion 3421. The first convex portion 3421 protrudes from the first part 341 in the second direction. It can be understood that the projection of the first convex portion 3421 in the plane perpendicular to the first direction is located outside the projection of the first part 341 in the plane perpendicular to the first direction. This plane perpendicular to the first direction can be understood as any plane perpendicular to the first direction, such as the end face of the liquid storage cup 34 at one end in the first direction.

[0032] The second direction can be understood as any direction in the plane perpendicular to the first direction. For example, the outer contour of the liquid storage cup 34 can be generally set as a cuboid structure. The height dimension of the liquid storage cup 34 is greater than the length dimension of the liquid storage cup 34, and the length dimension of the liquid storage cup 34 is greater than the width dimension of the liquid storage cup 34. The first direction can be understood as the height direction of the liquid storage cup 34, and the second direction can be understood as the width direction of the liquid storage cup 34. Or in other embodiments, the second direction can also be understood as the length direction of the liquid storage cup 34 or the second direction has an angle less than 90° with the width direction of the liquid storage cup 34.

[0033] The entire atomizer 3 is located within the atomization housing 1 of the atomization device. The atomization housing 1 has a cavity 13, and auxiliary components are also provided within the atomization housing 1. For example, the auxiliary components may include one or more of a battery cell 22, a circuit board 23, a display screen 21, and buttons. The auxiliary components can be arranged at intervals in any direction perpendicular to the first direction with respect to the atomizer 3. For example, the auxiliary components are arranged with respect to the atomizer 3 in the second direction. The dimension of the auxiliary components in the first direction can be smaller than the dimension of the atomizer 3 in the first direction. In this way, after the auxiliary components are first installed within the atomization housing 1, there will be some space left on one side of the auxiliary components in the first direction within the atomization housing 1. When installing the atomizer 3, the dimension of the first portion 341 of the liquid storage cup 34 in the first direction is slightly larger than the dimension of the auxiliary components in the first direction, so as to ensure that the first portion 341 of the liquid storage cup 34 can correspond to the auxiliary components in the first direction. Additionally, the first portion 341 of the liquid storage cup 34 is arranged with respect to the auxiliary components in the second direction, and the second portion 342 is arranged with respect to the auxiliary components in the first direction. Moreover, the first convex portion 3421 in the second portion 342 fills the space on one side of the auxiliary components in the first direction within the atomization housing 1. In this way, while the liquid storage capacity in the liquid storage cup 34 can be increased through the first convex portion 3421, the first convex portion 3421 is used to fill the redundant space within the atomization housing 1, so as to improve the space utilization rate within the atomization housing 1 and avoid waste of the space within the atomization housing 1.

[0034] In one embodiment, please refer to Figures 3 to 6 , the liquid storage cup 34 has a cross-section arranged perpendicular to the first direction. The cross-sectional area of the second portion 342 is larger than the cross-sectional area of the first portion 341. The first portion 341 and the second portion 342 of the liquid storage cup 34 are respectively arranged at both ends of the liquid storage cup 34 in the first direction. In this way, the liquid storage cup 34 forms a structure with one end large and one end small. In any plane perpendicular to the first direction, the orthographic projection of the second portion 342 is set to cover the orthographic projection of the first portion 341, and a part of the outer contour of the orthographic projection of the first portion 341 coincides with a part of the outer contour of the orthographic projection of the second portion 342. Only the orthographic projection corresponding to the first convex portion 3421 in the second portion 342 is located outside the orthographic projection of the first portion 341. This makes the outer side surfaces extending in the first direction on the part of the second portion 342 other than the first convex portion 3421 coplanar with the outer side surfaces extending in the first direction on the first portion 341. In this way, it is convenient for the processing and manufacturing of the entire liquid storage cup 34.

[0035] Certainly, in other embodiments, while the cross-sectional area of the second part 342 is larger than that of the first part 341, it is also possible to set that the part of the second part 342 that is arranged opposite to the first convex part 3421 in the second direction is concave, that is, the first part 341 has a convex part that is arranged opposite to the first convex part 3421 in the second direction. Or it is also possible to set that the cross-sectional area of the second part 342 is equal to the cross-sectional area of the first part 341.

[0036] In one embodiment, it can be set that the first convex part 3421 in the second part 342 is arranged around the first part 341 in the circumferential direction around the first direction, that is, in any plane perpendicular to the first direction, the orthographic projection of the first convex part 3421 surrounds the orthographic projection of the first part 341. In this way, in the structure where auxiliary components are arranged around the first part 341 in the atomizing housing 1, the space inside the atomizing housing 1 can be fully and effectively utilized, and the waste of redundant space inside the atomizing housing 1 can be avoided.

[0037] Certainly, in other embodiments, it is also possible to set the length direction of the liquid storage cup 34 as the third direction, and it is also possible to set that in a plane perpendicular to the first direction, the orthographic projection of the first convex part 3421 in the second part 342 semi-surrounds the orthographic projection of the first part 341. For example, when the length direction of the liquid storage cup 34 is set as the third direction, the first convex part 3421 protrudes outward relative to the first part 341 on one side in the second direction, and also protrudes outward relative to the first part 341 on one side in the third direction. In this way, in the structure where auxiliary components are arranged on one side in the second direction and one side in the third direction inside the atomizing housing 1, the first convex part 3421 can make full use of the space on one side of the auxiliary components in the first direction, and the waste of space inside the atomizing housing 1 can be avoided.

[0038] In one embodiment, please refer to Figures 3 to 6 , the outer contour shape of the first convex part 3421 is generally a cuboid, which is convenient for the processing and manufacturing of the first convex part 3421 and the entire liquid storage cup 34. It is set that the first convex part 3421 has a first convex side surface 3422 that faces away from the liquid storage cavity in the second direction, and the corresponding first part 341 has a first outer side surface 3412 that is arranged facing away from the liquid storage cavity in the second direction. The first convex side surface 3422 and the first outer side surface 3412 are on the same side of the liquid storage cavity in the second direction. It is set that both the first convex side surface 3422 and the first outer side surface 3412 extend in the first direction, and the first convex side surface 3422 and the first outer side surface 3412 are spaced apart in the second direction, so as to facilitate the molding and demolding of the entire liquid storage cup 34.

[0039] Of course, according to the shape of the auxiliary components in the atomization housing 1, the shape of the inner side wall of the atomization housing 1, and the inclination angle, the first convex outer side surface 3422 and / or the first outer side surface 3412 can be set to have a smaller included angle with the first direction. An appropriate included angle is set to enable the liquid storage cup 34 to have a certain draft angle, which facilitates the molding and demolding of the liquid storage cup 34 and helps improve the yield of the liquid storage cup 34.

[0040] In one embodiment, please continue to refer to Figures 3 to 6 , the first convex outer side surface 3422 and the first outer side surface 3412 can be connected by a connecting outer side surface 344. The connecting outer side surface 344 is set to be perpendicular to the first direction, and a parting surface of the liquid storage cup 34 can be formed at the connecting outer side surface 344 to facilitate the processing and production of the entire liquid storage cup 34. Of course, it is also possible to set an included angle less than 90° between the connecting outer side surface 344 and the first direction. In this way, the parting surface of the liquid storage cup 34 can be set on the end surfaces at both ends of the liquid storage cup 34 in the first direction, which can also facilitate the demolding and molding of the liquid storage cup 34.

[0041] In some embodiments, please refer to Figure 3 , the atomization housing 1 can include an upper housing 11 and a lower housing 12. After the upper and lower housings are inserted and combined, a cavity 13 is formed. The wall thickness of the housing at the insertion position of the upper housing 11 and the lower housing 12 is greater than the wall thickness of the remaining part of the upper housing 11. In this way, a concave space is formed between the position with a relatively thick wall thickness of the atomization housing 1 and the cavity wall on one side of the cavity 13 in the first direction.

[0042] In some other embodiments, the wall thickness of the atomization housing 1 can also be set to be equal everywhere in the first direction. There are multiple auxiliary components in the atomization housing 1, and the sizes of two auxiliary components arranged in the first direction are unequal in the second direction. In this way, a concave space is formed on one side of the auxiliary component with a smaller size in the second direction.

[0043] In some other embodiments, auxiliary components such as a display screen 21 or a button are installed on the atomization housing 1. In this case, an installation part 14 for installing the auxiliary components needs to be provided on the atomization housing 1. The size of the installation part 14 in the first direction is greater than the size of the auxiliary component in the first direction, and the auxiliary component protrudes into the cavity 13 relative to the installation part 14. The installation part 14 protrudes into the cavity 13 relative to the outermost shell wall of the atomization housing 1. In this way, a concave space is formed between the installation part 14 and the cavity wall on one side of the cavity 13 in the first direction.

[0044] In order to make full use of the above concave space to realize the full utilization of the space inside the atomization housing 1. In some embodiments, please refer to Figure 6, it is also possible to set the liquid storage cup 34 to include a third part 343, which is located on the side of the second part 342 facing away from the first part 341 in the first direction. The third part 343 is connected to the second part 342, and the entire liquid storage cup 34 can be made by an integrally injection-molded method. The third part 343 is provided with a second convex part 3431, and the second convex part 3431 protrudes relative to the second part 342 in the second direction. The second convex part 3431 can be used to fill the concave space in the atomization housing 1 to make full use of the space in the atomization housing 1; or it can also be understood that the second part 342 and the first part 341 are concave relative to the second convex part 3431, and the relatively concave second part 342 and the first part 341 can be used to avoid a plurality of auxiliary components in the atomization housing 1, or avoid the auxiliary components in the atomization housing 1 and the mounting part 14 on the atomization housing 1 for mounting the auxiliary components, or avoid the auxiliary components in the atomization housing 1 and the positions with relatively thick wall thickness on the atomization housing 1, so that the outer contour shape of the liquid storage cup 34 adapts to the space shape outside the auxiliary components in the atomization housing 1, thereby improving the utilization rate of the internal cavity 13 of the atomization housing 1, and at the same time helping to increase the volume and liquid storage capacity of the liquid storage cup 34.

[0045] In one embodiment, the third part 343 also has a cross-section arranged perpendicular to the first direction, and the cross-sectional area of the third part 343 is larger than the cross-sectional area of the second part 342. In this way, the cross-sectional area of the liquid storage cup 34 in the first direction gradually increases from the first part 341 to the third part 343. In any plane perpendicular to the first direction, it is set that the orthographic projection of the third part 343 covers the orthographic projection of the second part 342, and a part of the outer contour of the orthographic projection of the third part 343 coincides with a part of the outer contour of the orthographic projection of the second part 342. Only the orthographic projection of the second convex part 3431 in the third part 343 is located outside the orthographic projection of the second part 342. In this way, the outer side surface extending in the first direction on the part of the third part 343 other than the second convex part 3431 is coplanar with the outer side surface extending in the first direction on the second part 342, which is convenient for the processing and manufacturing of the entire liquid storage cup 34.

[0046] Of course, in some other embodiments, according to the arrangement of a plurality of auxiliary components in the atomization housing 1 in the first direction, the third part 343 in the liquid storage cup 34 can also be set to be connected between the first part 341 and the second part 342 to adapt to the structure in which two auxiliary components in the atomization housing 1 are arranged at intervals in the first direction and the space outside the auxiliary components in the atomization housing 1 has a larger cross-section in the middle cross-section in the first direction.

[0047] In one embodiment, the second convex portion 3431 can also be arranged to surround the second portion 342 in a plane perpendicular to the first direction, that is, the orthographic projection of the second convex portion 3431 in the plane perpendicular to the first direction surrounds the orthographic projection of the second portion 342 in the plane perpendicular to the first direction, so as to adapt to the structure in which auxiliary components are arranged around the liquid storage cup 34 inside the atomization housing 1 or a portion with a relatively thick wall thickness on the atomization housing 1 surrounds the liquid storage cup 34 for one week.

[0048] Of course, the second convex portion 3431 can also protrude from the second portion 342 on both sides in the second direction, or the second convex portion 3431 protrudes from the second portion 342 on one side in the second direction and one side in the third direction, so as to adapt to the structure in which the auxiliary components inside the atomization housing 1 have multiple angular placement positions.

[0049] In one embodiment, please refer to Figure 6 , the first convex portion 3421 and the second convex portion 3431 protrude toward the same side in the second direction, and the side surface of the first portion 341 that is arranged opposite to the first convex portion 3421 in the second direction, the side surface of the second portion 342 that is arranged opposite to the first convex portion 3421 in the second direction, and the side surface of the third portion 343 that is arranged opposite to the first convex portion 3421 in the second direction are coplanar, which is convenient for the integral molding of the entire liquid storage cup 34.

[0050] Furthermore, it can also be set that the outer side surfaces perpendicular to the third direction on the first portion 341, the outer side surfaces perpendicular to the third direction on the second portion 342, and the outer side surfaces perpendicular to the third direction on the third portion 343 are all coplanar. In this way, only one outer side surface of the liquid storage cup 34 in the second direction is non-coplanar, and the other outer side surfaces are coplanar, which is convenient for the integral molding of the liquid storage cup 34.

[0051] In one embodiment, please continue to refer to Figure 6 , it is set that the second convex portion 3431 has a second convex side surface 3432 arranged opposite to the liquid storage cavity in the second direction, the first convex portion 3421 has a first convex side surface 3422 arranged opposite to the liquid storage cavity in the second direction, the first portion 341 has a first outer side surface 3412 arranged opposite to the liquid storage cavity in the second direction. The first outer side surface 3412, the first convex side surface 3422, and the second convex side surface 3432 are all located on the same side of the liquid storage cavity in the second direction, and the first outer side surface 3412, the first convex side surface 3422, and the second convex side surface 3432 all extend in the first direction. The first outer side surface 3412, the first convex side surface 3422, and the second convex side surface 3432 are spaced apart from each other in the second direction in pairs, and the first convex side surface 3422 is located between the second convex side surface 3432 and the first convex side surface 3422, so that the three form three stepped surfaces of a stepped structure, so as to facilitate the design of the mold for the liquid storage cup 34 and facilitate the demolding of the liquid storage cup 34.

[0052] Further, in another embodiment, the first outer side surface 3412, the first outwardly convex side surface 3422, and the second outwardly convex side surface 3432 may all be provided with draft angles to facilitate the smooth demolding of the liquid storage cup 34 from the mold, which helps to improve the yield rate of the liquid storage cup 34.

[0053] Of course, the second outwardly convex side surface 3432 and the first outwardly convex side surface 3422 are connected by an outer side surface arranged perpendicular to the first direction to facilitate the structural design of the liquid storage cup 34.

[0054] In some embodiments, please refer to Figure 2 and Figure 3 , the atomizer further includes a liquid storage member 35. The liquid storage member 35 is located in the liquid storage cavity. The liquid storage member 35 can be a liquid storage cotton. The liquid storage member 35 can absorb a large amount of atomized liquid to prevent the atomized liquid from flowing out of the atomization channel 31. The shape of the liquid storage member 35 can be set according to the shape of the liquid storage cavity in the liquid storage cup 34, so that the shape of the liquid storage member 35 adapts to the shape of the liquid storage cavity, thereby increasing the volume of the liquid storage member 35 and the amount of atomized liquid that can be absorbed in the liquid storage member 35.

[0055] In one embodiment, the liquid storage member 35 is integrally formed to facilitate the assembly of the liquid storage member 35 in the atomizer 3. In another embodiment, the liquid storage member 35 can be separately provided according to the structure of the inner and outer convex parts of the liquid storage cavity. For example, the liquid storage member 35 can be provided with three liquid storage parts according to the first part 341, the second part 342, and the third part 343 of the liquid storage cup 34, and each liquid storage part is respectively located in the liquid storage cavity corresponding to the three parts of the liquid storage cup 34; or two smaller liquid storage parts can be respectively provided on the first outer convex part 3421 and the second outer convex part 3431, so that these two smaller liquid storage parts are separately provided from the larger liquid storage part located in the first part and extending to the second part and the third part; the separately provided liquid storage member 35 is convenient for processing and manufacturing, and is also convenient for the installation of the liquid storage member 35 in the liquid storage cavity.

[0056] The embodiment of the present application also discloses an atomization device. Please refer to Figure 1 , the atomization device includes an atomization housing 1, auxiliary components, and the atomizer 3 in any of the above embodiments. The atomization housing 1 has a cavity 13. The auxiliary components and the atomizer 3 are both located in the cavity 13 of the atomization housing 1. The atomization housing 1 can be set as a split structure. For example, the atomization housing 1 can be set to include an upper housing 11 and a lower housing 12, and the upper and lower housings are inserted and assembled to enclose and form the cavity 13.

[0057] The auxiliary components may include one or more of the battery cell 22, the display screen 21, the button, and the circuit board 23. The auxiliary components are installed in the cavity 13. During the assembly process of the atomization device, the specific positions of the auxiliary components in the cavity 13 can be set according to the circuit layout. Some auxiliary components such as the display screen 21 and the button need to be installed on the atomization housing 1. In this case, an installation portion 14 for installing the auxiliary components needs to be provided on the atomization housing 1. The installation portion 14 protrudes toward the cavity 13, thus forming a cavity 13 structure with an irregular outer contour shape inside the atomization housing 1. In addition, due to the different shapes and sizes of the auxiliary components, after the auxiliary components are installed in the atomization housing 1, a plurality of concave spaces will be formed in the cavity 13 inside the atomization housing 1. For example, a concave space can be formed between the auxiliary component and the end side wall of the atomization housing 1 in the first direction, or between the installation portion 14 and the end side wall of the atomization housing 1.

[0058] In this application, the structure of the liquid storage cup 34 in the atomizer 3 is mainly designed according to the spatial structure inside the atomization housing 1 for installing the atomizer 3. A first outward protrusion 3421 is provided on the liquid storage cup 34, or a second outward protrusion 3431 can also be provided, so that the first outward protrusion 3421 and the second outward protrusion 3431 fill the concave space inside the atomization housing 1, thereby increasing the volume of the liquid storage cup 34 and the liquid storage amount in the liquid storage cup 34 while improving the utilization rate of the internal space of the atomization housing 1 and avoiding waste of the internal space of the atomization housing 1.
