[0043] Referring to Figures 1 to 11 According to the atomizer of the embodiments of the present application, the atomizer comprises an oil cup 100, a support 200 and an atomization core 300.

[0044] Specifically, the oil cup 100 has an opening 110 at one end along a first direction, an air outlet 120 is arranged on a side wall of the oil cup 100, the support 200 is arranged in the opening 110, the support 200 is provided with a mounting groove 210 and an atomizing groove 220 in communication with the mounting groove 210 on a side of the support 200 facing 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 in sealing contact with the inner side wall of the oil cup 100, the support 200 is provided with an air inlet groove 250 and an air outlet groove 260, 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 in communication with one end of the atomizing groove 220, the air outlet groove 260 is in communication with 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, the atomizing core 300 and the atomizing groove 220 enclose an atomizing passage a, and the atomizing core 300, the support 200 and the oil cup 100 enclose a liquid storage cavity b on a side of the atomizing core 300 away from the atomizing groove 220.

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

[0046] The atomizing core 300 can be assembled on the support 200 through the mounting groove 210, wherein the atomizing passage a in the airflow passage of the atomizer can be enclosed by the atomizing core 300 and the support 200, compared with the traditional atomizer, without the need for additional atomizing supports, airway parts, sealing parts and other components, thereby simplifying the related structure to reduce the required components, facilitating to reduce the assembly difficulty to improve the production efficiency, and facilitating to reduce the production cost. In addition, the air inlet groove 250 for the air inlet of the atomizing groove 220 and the air outlet groove 260 for the air outlet of the atomizing groove 220 arranged on the support 200 are 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 in sealing contact with the inner side wall of the oil cup 100, which not only effectively isolates the atomizing passage a from the liquid storage cavity b, but also effectively isolates the atomizing passage a from the opening 110 of the oil cup 100, thereby increasing the difficulty of the atomized liquid in the liquid storage cavity b flowing into the atomizing passage 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, and the risk of liquid leakage can be reduced.

[0047] Referring to Figure 2 and Figure 3 and Figures 6 to 9In some embodiments, the first sealing portion 230 is arranged on the side of the second sealing portion 240 facing the liquid storage cavity b, i.e., the first sealing portion 230 is closer to the liquid storage cavity b than the second sealing portion 240. The first sealing portion 230 is arranged on the outer side wall of the mounting groove 210. After assembly, the first sealing portion 230 is pressed by the inner side wall of the oil cup 100, so that the side wall of the mounting groove 210 is pressed, thereby making the contact between the atomizing core 300 and the inner side wall of the mounting groove 210 more closely, which is conducive to improving the sealing between the atomizing core 300 and the inner side wall of the mounting groove 210, and further conducive to increasing the difficulty of the atomized liquid in the liquid storage cavity b flowing into the atomizing channel a through the mounting groove 210.

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

[0049] In some embodiments, the support 200 is a flexible member made of silica gel or rubber, thereby enhancing the above-mentioned pressing effect, and further conducive to improving the sealing effect.

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

[0051] Referring to Figures 2 to 4 and Figure 6 , Figure 7 , Figure 10 and Figure 11 In some embodiments, the atomizing core 300 includes a liquid guide member 310 and a heating member 320. The liquid guide member 310 has a liquid absorbing surface 311 and an atomizing surface 312 arranged opposite in the first direction. The heating member 320 is arranged on the atomizing surface 312. The liquid absorbing surface 311 is in fluid communication with the liquid storage cavity b. The atomizing surface 312 covers the slot of the atomizing groove 220 that is in communication with the mounting groove 210, so as to enclose the atomizing channel a. In use, the liquid guide member 310 absorbs the atomized liquid in the liquid storage cavity b through the liquid absorbing surface 311. The atomized liquid absorbed by the liquid absorbing surface 311 flows to the atomizing surface 312 and is heated and atomized by the heating member 320, so as to form the inhalable aerosol into the atomizing channel a.

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

[0053] It should be noted that in some other embodiments, the liquid guide 310 can also be a flexible porous body, which is not limited here. Specifically, the liquid guide 310 can be made of oil guiding 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 can also be a heating net or a conductive coating coated on the atomizing surface 312, which is not limited here.

[0056] With reference to Figure 5 , Figure 6 and Figure 9 , in some embodiments, the atomizer further comprises an air inlet channel having an air inlet 271 arranged 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 271 is higher than that of the air inlet groove 250, i.e., the air inlet 271 is closer to the air outlet 120 than the air inlet groove 250. In this way, under normal circumstances, the height of the air inlet 271 along the gravity direction is higher than that of the air inlet groove 250, thereby increasing the difficulty of the atomized liquid leaked into the air inlet groove 250 or the condensed liquid formed in the air inlet groove 250 flowing out through the air inlet 271.

[0057] With reference to Figure 2 , Figure 4 , Figure 5 , Figure 6 and Figure 9 , in some embodiments, the air inlet channel comprises an air inlet section 272 arranged on the support 200 and extending along the first direction. One end of the air inlet section 272 is connected to the air inlet groove 250, and the other end of the air inlet section 272 forms the air inlet 271 on the side of the support 200 away from the atomizing core 300, i.e., the air inlet 271 is formed on the support 200, and the air inlet 271 is located on the side of the support 200 away from the oil cup 100 along the first direction. In this case, it is not necessary to arrange an air inlet structure on the oil cup 100 for the air inlet channel, which is conducive to reducing the processing difficulty.

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

[0059] With reference to Figure 5 , Figure 6 and Figure 9In some embodiments, the air inlet channel further comprises an air outlet section 273 arranged on the support 200, the air outlet section 273 being in communication with the air inlet section 272 and the air inlet groove 250, the air outlet section 273 extending in a direction intersecting both the air inlet section 272 and the atomization groove 220, on the one hand, the air outlet section 273 can increase the difficulty of the aerosol formed in the atomization channel a flowing out through the air inlet channel, i.e., can reduce the problem of air flow backflow, on the other hand, the air outlet section 273 can increase 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, i.e., can reduce the risk of liquid leakage.

[0060] Specifically, the air inlet section 272 extends in a first direction, the air outlet section 273 extends in a second direction, and the atomization groove 220 extends in 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 direction of gravity), and at this time, the first direction and the second direction are both the transverse direction of the support 200 (i.e., the direction parallel to the horizontal plane).

[0062] Referring to Figure 5 , Figure 6 and Figure 9 , in some embodiments, the air inlet groove 250 comprises a first section 251 and a second section 252 in communication with each other, the first section 251 extends in the same direction as the air outlet section 273, the first section 251 and the air outlet section 273 are arranged in the extension direction of the atomization groove 220, and the first section 251 is farther away from the air inlet 271 than the air outlet section 273, the second section 252 is in communication with the air outlet section 273 and the first section 251, and the end of the first section 251 away from the second section 252 is connected to the 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, i.e., the problem of air flow backflow 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, i.e., the risk of liquid leakage can be reduced.

[0063] Referring to Figure 5 , Figure 6 and Figure 9 , in some embodiments, the second section 252 is arc-shaped, which is beneficial to improve the smoothness of the air inlet flow entering the first section 251 from the air outlet section 273.

[0064] Referring to Figures 1 to 3In some embodiments, a limiting step 130 is arranged on the inner side wall of the oil cup 100, and the support 200 abuts against the limiting step 130 at the edge of the side of the oil cup 100 in the first direction, so as to facilitate positioning of the support 200, thereby facilitating reduction of assembly difficulty.

[0065] With reference to Figure 4 In some embodiments, the liquid storage cavity b is filled with a liquid storage member 400, one end of the liquid storage member 400 abuts against the side of the atomization core 300 away from the atomization groove 220, and the other end of the liquid storage member 400 abuts against the inner wall of the oil cup 100 toward the opening 110 (i.e., the inner wall of the end of the oil cup 100 away from the opening 110), and the atomization core 300 and the inner wall of the oil cup 100 toward the opening 110 compress the liquid storage member 400 in the first direction, so that the length of the liquid storage member 400 in the first direction after assembly is smaller than the length of the liquid storage member 400 in the first direction before assembly, so that the liquid storage member 400 and the atomization core 300 can be tightly fitted, thereby reducing the risk of poor contact between the liquid storage member 400 and the atomization core 300, for example, the liquid storage member 400 cannot contact the atomization core 300 when the atomizer is tilted, so that the liquid storage member 400 can stably supply atomization liquid to the atomization core 300, thereby reducing the risk of dry burning of the heating element 320 of the atomization core 300. In addition, by arranging the liquid storage member 400, the atomization liquid in the liquid storage cavity b is locked, thereby reducing the risk of liquid leakage.

[0066] It should be noted that the dashed arrows in the drawings are the flow paths of the air inlet flow.

[0067] With reference to Figure 12 And Figure 13 According to the electronic atomization device of the embodiments of the present application, the electronic atomization device comprises a power supply device and the above-mentioned atomizer, and the power supply device is connected with the atomizer and used for supplying power to the atomizer.

[0068] It should be noted that, since the electronic atomization device of the embodiments of the present application comprises the above-mentioned atomizer, the electronic atomization device of the embodiments of the present application comprises all the technical effects of the above-mentioned atomizer.
