[0043] Reference Figures 1 to 11 The atomizer according to the embodiment of the present application includes an oil cup 100 , a support 200 and an atomizing core 300 .

[0044] Specifically, the oil cup 100 has an opening 110 at one end along the first direction, an air outlet 120 is arranged on the side wall of the oil cup 100, and the support 200 is arranged in the opening 110. The support 200 is provided with a mounting groove 210 and an atomization groove 220 connected to the mounting groove 210 on one side of the support 200 facing the inside of the oil cup 100 along the first direction. The support 200 is provided with a first sealing portion 230 and a second sealing portion 240 spaced apart along the first direction. The first sealing portion 230 and the second sealing portion 240 are both in sealing contact with the inner side wall of the oil cup 100. An air inlet groove 250 and an air outlet groove 260 are provided, and both the air inlet groove 250 and the air outlet groove 260 are located between the first sealing portion 230 and the second sealing portion 240. The air inlet groove 250 is connected to one end of the atomizing groove 220, and the air outlet groove 260 is connected to the other end of the atomizing groove 220 and leads to the air outlet 120. The atomizing core 300 is arranged in the mounting groove 210, and the atomizing core 300 and the atomizing groove 220 are enclosed to form an atomizing channel a. The atomizing core 300, the support 200 and the oil cup 100 are enclosed to form a liquid storage chamber b located on the side of the atomizing core 300 facing away from the atomizing groove 220.

[0045] It should be noted that the first direction mentioned above is the X direction in the drawings.

[0046] The atomizer core 300 can be assembled on the support 200 through the mounting groove 210, wherein the atomizer channel a in the air flow channel of the atomizer can be enclosed by the atomizer core 300 and the support 200. Compared with the traditional atomizer, there is no need to additionally set up atomizer brackets, airway parts, sealing parts and other parts, thereby simplifying the relevant structure to reduce the required parts, which is beneficial to reducing the difficulty of assembly to improve production efficiency, and at the same time is beneficial to reducing production costs. In addition, the air inlet groove 250 for air intake of the atomizing groove 220 and the air outlet groove 260 for air outlet of the atomizing groove 220 provided on the support 200 are both located between the first sealing portion 230 and the second sealing portion 240, and the first sealing portion 230 and the second sealing portion 240 are both in sealing contact with the inner wall of the oil cup 100, which can not only effectively isolate the atomizing channel a from the liquid storage chamber b, but also effectively isolate the atomizing channel a from the opening 110 of the oil cup 100, thereby increasing the difficulty of the atomized liquid in the liquid storage chamber b flowing into the atomizing channel a and leaking to the outside through the opening 110 of the oil cup 100. Compared with the traditional atomizer, the sealing effect can be improved, which is beneficial to reduce the risk of leakage.

[0047] Reference Figure 2 and Figure 3 as well as Figures 6 to 9In some embodiments, the first sealing portion 230 is disposed on the side of the second sealing portion 240 facing the liquid storage chamber b, that is, the first sealing portion 230 is closer to the liquid storage chamber b than the second sealing portion 240, and the first sealing portion 230 is disposed on the outer side wall of the mounting groove 210 corresponding to the atomizer core 300. After assembly, the first sealing portion 230 will be squeezed by the inner side wall of the oil cup 100, so that the side wall of the mounting groove 210 is squeezed, thereby making the contact between the atomizer core 300 and the inner side wall of the mounting groove 210 closer, which is beneficial to improving the sealing between the atomizer core 300 and the inner side wall of the mounting groove 210, and further beneficial to increasing the difficulty of the atomized liquid in the liquid storage chamber b flowing into the atomization channel a through the mounting groove 210.

[0048] Specifically, the oil cup 100 is a rigid part, and the oil cup 100 can be made of hard non-metallic materials such as plastic, or can be made of hard metal materials such as stainless steel, which is not limited here.

[0049] In some of the embodiments, the support 200 is a flexible member made of silicone or rubber, so as to enhance the above-mentioned squeezing effect and further help improve the sealing effect.

[0050] It should be noted that in some other embodiments, the support 200 may also be a rigid member. Specifically, the support 200 may be made of hard non-metallic materials such as plastic, or may be made of hard metal materials such as stainless steel, which is not limited here. At this time, the side wall of the mounting groove 210 is a weak structure, which can be deformed to a certain extent under the extrusion effect, and can also make the contact between the atomizer core 300 and the inner side wall of the mounting groove 210 closer.

[0051] Reference Figures 2 to 4 as well as Figure 6 , Figure 7 , Fig.10 and Fig.11 In some embodiments, the atomization core 300 includes a liquid guide 310 and a heating element 320. The liquid guide 310 has a liquid absorption surface 311 and an atomization surface 312 arranged opposite to each other along a first direction. The heating element 320 is arranged on the atomization surface 312. The liquid absorption surface 311 is in fluid communication with the liquid storage chamber b. The atomization surface 312 covers the notch of the atomization slot 220 that is connected to the mounting slot 210 to enclose and form an atomization channel a. When in use, the liquid guide 310 absorbs the atomized liquid in the liquid storage chamber b through the liquid absorption surface 311. The atomized liquid absorbed by the liquid absorption surface 311 flows to the atomization surface 312 and is heated and atomized by the heating element 320 to form an inhalable aerosol leading to the atomization channel a.

[0052] In some embodiments, the liquid guide 310 is a hard porous body. Specifically, the liquid guide 310 can be made of porous glass or porous ceramics.

[0053] It should be noted that in some other embodiments, the liquid guide member 310 may also be a flexible porous body, which is not limited here. Specifically, the liquid guide member 310 may be made of oil-conducting cotton or integrated cotton.

[0054] In some embodiments, the heating element 320 is a metal heating sheet.

[0055] It should be noted that, in some other embodiments, the heating element 320 may also be a heating net or a conductive coating coated on the atomized surface 312, which is not limited here.

[0056] Reference Figure 5 , Figure 6 and Fig. 9 In some embodiments, the atomizer further includes an air inlet channel having an air inlet port 271 disposed on the oil cup 100 or the support 200 and connected to the air inlet groove 250. Along the extension direction of the atomizing groove 220, the height of the air inlet port 271 is higher than the height of the air inlet groove 250, that is, the air inlet port 271 is closer to the air outlet 120 relative to the air inlet groove 250. In this way, under normal circumstances, the height of the air inlet port 271 along the gravity direction can be higher than the air inlet groove 250, thereby increasing the difficulty of the atomized liquid leaking into the air inlet groove 250 or the condensed liquid formed in the air inlet groove 250 flowing out through the air inlet port 271.

[0057] Reference Figure 2 , Figure 4 , Figure 5 , Figure 6 and Fig. 9 In some embodiments, the air inlet channel includes an air inlet section 272 disposed on the support 200 and extending along the first direction, one end of the air inlet section 272 is communicated with the air inlet groove 250, and the other end of the air inlet section 272 forms an air inlet port 271 on a side of the support 200 facing away from the atomizer core 300, that is, the air inlet port 271 is formed on the support 200, and the air inlet port 271 is located on a side of the support 200 facing the outside of the oil cup 100 along the first direction. In this case, there is no need to set an air inlet structure on the oil cup 100 for the air inlet channel, which is conducive to reducing the difficulty of processing.

[0058] It should be noted that, in some other embodiments, the air inlet 271 may also be formed on the side wall of the oil cup 100 , which is not limited here.

[0059] Reference Figure 5 , Figure 6 and Fig. 9In some embodiments, the air inlet channel also includes an air outlet section 273 arranged on the support 200, the air outlet section 273 connects the air inlet section 272 and the air inlet groove 250, and the extension direction of the air outlet section 273 intersects with the extension direction of the air inlet section 272 and the extension direction of the atomization groove 220 at the same time. On the one hand, it can increase the difficulty of the aerosol formed in the atomization channel a to flow out through the air inlet channel, that is, it can reduce the problem of air flow back. On the other hand, it can increase the difficulty of the atomized liquid leaking into the atomization channel a or the condensed liquid formed in the atomization channel a to flow out through the air inlet channel, that is, it can reduce the risk of leakage.

[0060] Specifically, the air inlet section 272 extends along a first direction, the air outlet section 273 extends along a second direction, and the atomization groove 220 extends along a third direction, wherein the second direction is the Y direction in the drawing, and the third direction is the Z direction in the drawing.

[0061] Specifically, in some embodiments, the first direction, the second direction and the third direction are perpendicular to each other, wherein the third direction can be the longitudinal direction of the support 200 (i.e., the direction parallel to the gravity direction). At this time, the first direction and the second direction are both transverse directions of the support 200 (i.e., the direction parallel to the horizontal plane).

[0062] Reference Figure 5 , Figure 6 and Fig. 9 In some embodiments, the air inlet groove 250 includes a first section 251 and a second section 252 that are interconnected. The extension direction of the first section 251 is consistent with the extension direction of the air outlet section 273. The first section 251 and the air outlet section 273 are spaced apart along the extension direction of the atomization groove 220. Along the extension direction of the atomization groove 220, the first section 251 is farther away from the air inlet 271 than the air outlet section 273. The second section 252 connects the air outlet section 273 and the first section 251. One end of the first section 251 away from the second section 252 is connected to one end of the atomization groove 220 away from the air outlet groove 260. In this way, the extension length of the air inlet groove 250 can be increased. On the one hand, the difficulty of the aerosol formed in the atomization channel a flowing out through the air inlet channel can be further increased, that is, the problem of airflow back-spitting can be reduced. On the other hand, the difficulty of the atomized liquid leaking into the atomization channel a or the condensed liquid formed in the atomization channel a flowing out through the air inlet channel can be further increased, that is, the risk of liquid leakage can be reduced.

[0063] Reference Figure 5 , Figure 6 and Fig. 9 In some of the embodiments, the second section 252 is arc-shaped, which helps to improve the smoothness of the intake air flow from the outlet section 273 into the first section 251.

[0064] Reference Figures 1 to 3In some of the embodiments, a limiting step 130 is provided on the inner wall of the oil cup 100, and the edge of the support 200 along the first direction toward the inside of the oil cup 100 is abutted against the limiting step 130, which facilitates positioning of the support 200 during assembly, thereby helping to reduce the difficulty of assembly.

[0065] Reference Figure 4 In some embodiments, the liquid storage chamber b is filled with a liquid storage member 400, one end of the liquid storage member 400 is pressed against the side of the atomizer core 300 facing away from the atomizer groove 220, and the other end of the liquid storage member 400 is pressed against the inner wall of the oil cup 100 facing the opening 110 (i.e., the inner wall of the end of the oil cup 100 away from the opening 110), and the inner wall of the atomizer core 300 and the oil cup 100 facing the opening 110 compresses the liquid storage member 400 along the first direction, so that the liquid storage member 400 is in a compressed state, that is, after the liquid storage member 400 is assembled The length dimension along the first direction is smaller than the length dimension in the first direction before the liquid storage member 400 is assembled, so that the liquid storage member 400 and the atomizer core 300 can fit closely together, which is conducive to reducing the poor contact between the liquid storage member 400 and the atomizer core 300, for example, the liquid storage member 400 cannot contact the atomizer core 300 when the atomizer is tilted, so that the liquid storage member 400 can stably supply atomized liquid to the atomizer core 300, thereby helping to reduce the risk of dry burning of the heating element 320 of the atomizer core 300. In addition, by providing the liquid storage member 400, a certain locking effect is exerted on the atomized liquid in the liquid storage chamber b, which is conducive to reducing the risk of leakage.

[0066] It should be noted that the dotted arrows in the drawings represent the flow path of the intake air flow.
