Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0052] Referring to Figures 1 to 4 In one aspect, the electronic atomization device includes an oil cup 100 and an atomization assembly.

[0053] Specifically, the oil cup 100 has a liquid storage cavity 130; the atomization assembly includes a heating body 210, the heating body 210 includes a heating portion 211 and a supporting portion 212 connected with each other, wherein the electronic atomization equipment is provided with a lower oil hole 310 in communication with the liquid storage cavity 130, the atomization assembly is in fluid communication with the liquid storage cavity 130 through the lower oil hole 310, and the supporting portion 212 is at least partially arranged in overlap with the lower oil hole 310 of the liquid storage cavity 130.

[0054] It is worth understanding that the supporting portion 212 at least partially overlaps with the lower oil hole 310 means that at least part of the supporting portion 212 is located at the outlet end of the lower oil hole 310 and opposite to the lower oil hole 310. In this way, the supporting portion 212 can be in contact with the atomized liquid flowing out of the lower oil hole 310 and transfer heat to the atomized liquid at the position of the lower oil hole 310.

[0055] In the embodiments of the present application, the supporting portion 212 at least partially overlaps with the lower oil hole 310, and this part of the overlapping supporting portion 212 can transfer the heat of the atomization area to the lower oil hole 310, and can continuously transfer part of the heat to the atomized liquid flowing out of the lower oil hole 310, so that the atomized liquid molecules have enough energy to accelerate the random motion (Brownian motion), so as to accelerate the motion of the atomized liquid molecules, which helps to solve the problem of low flow rate of the atomized liquid. At the same time, the supporting portion is at least partially arranged to overlap with the lower oil hole 310, which can solve the problem of low oil guiding rate caused by the fact that the lower oil hole 310 is too far away from the atomization area and the oil flow rate is too slow, thereby helping to reduce the paste smell generated by the electronic atomization equipment. In addition, the lower oil hole 310 has a certain interval with the heating portion 211, and the heating temperature of the heating body 210 is mainly concentrated in the heating portion 211, that is, the temperature of the supporting portion 212 will not be too high, so that the volatilization speed of the flavoring substances will not be too fast, so as to effectively solve the problem of too fast volatilization of the flavoring substances.

[0056] In some specific embodiments, the heating portion 211 is a portion of the heating body 210 through which current flows after being powered on, and the supporting portion 212 is a portion of the heating body 210 through which no current flows after being powered on, that is, the heat of the supporting portion 212 is mainly the heat conducted by the heating portion 211, so as to reduce the heating temperature of the supporting portion 212.

[0057] In some embodiments of the present application, referring to Figure 3 and Figure 4The oil cup 100 comprises an oil cup body 110 and a breather pipe 120. The oil cup body 110 is a hollow structure, and the breather pipe 120 is at least partially arranged in the oil cup body 110. The breather pipe 120 has an atomization channel 121 formed in the interior thereof. The aerosol generated by the heating body 210 is heated and flows out through the atomization channel 121. One end of the atomization channel 121 is in communication with the suction nozzle, and the other end extends towards one end of the heating body 210, so that the aerosol generated by the heating body 210 can flow into the atomization channel 121 and flow to the suction nozzle for the user to smoke.

[0058] In a possible implementation, referring to Figure 3 and Figure 4 The breather pipe 120 and the oil cup body 110 are integrally formed, so that the sealing structure of the electronic atomization equipment can be simplified, and the leakage of the atomization liquid from the joint between the oil cup body 110 and the breather pipe 120 can be prevented.

[0059] It should be understood that the breather pipe 120 and the oil cup body 110 can also be a split structure, that is, the breather pipe 120 and the oil cup body 110 are assembled later to form the oil cup 100.

[0060] Further, referring to Figures 2 to 4 The electronic atomization equipment further comprises an atomization support 300, which is arranged in the oil cup body 110, and the atomization support 300, the oil cup body 110 and the breather pipe 120 jointly enclose a liquid storage cavity 130. The heating body 210 is arranged in the atomization support 300, and a lower oil hole 310 is formed in the atomization support 300.

[0061] Specifically, the oil cup body 110 is a hollow structure with one end open; the outer wall of the atomization support 300 is sealingly connected to the inner wall of the oil cup body 110; the lower end of the breather pipe 120 is a cantilever end, and the atomization support 300 is correspondingly provided with a connecting portion 320 sealingly connected to the cantilever end. The connecting portion 320 is provided with a docking interface 321 connected to the lower end of the breather pipe 120. During assembly, the outer peripheral wall of the atomization support 300 is matched with the inner wall of the oil cup body 110, and the connecting portion 320 of the atomization support 300 is sealingly connected to the cantilever end of the breather pipe 120, so that the oil cup body 110, the atomization support 300 and the breather pipe 120 jointly enclose the liquid storage cavity 130 for storing the atomization liquid.

[0062] In a possible implementation, referring to Figures 2 to 4The end of the atomization support 300 away from the liquid storage cavity 130 is provided with a sealing part 330, and the sealing part 330 includes a plurality of sealing protrusions arranged at intervals. Each sealing protrusion is in interference fit with the inner wall of the oil cup body 110 to achieve sealed connection. As an example, the atomization support 300 can be made of a flexible material, such as silica gel. In this way, the atomization support 300 can be in interference fit with the inner wall of the oil cup body 110 and the cantilever end of the air tube 120 to achieve sealed connection.

[0063] In some embodiments of the present application, referring to Figures 2 to 4 The atomization assembly includes a liquid guide 400 arranged between the lower oil hole 310 and the heating body 210. The liquid guide 400 has a liquid absorption surface and an atomization surface. The liquid absorption surface is opposite to the lower oil hole 310 and is sealed at the outlet end of the lower oil hole 310. The atomization surface is in abutment with the heating body 210. The atomization liquid in the liquid storage cavity 130 flows out of the lower oil hole 310 and is delivered to the atomization surface through the liquid guide 400. Then, the atomization liquid is heated and atomized by the heating body 210 at the atomization surface to generate aerosol mist.

[0064] It should be noted that the liquid guide 400 can be oil guiding cotton or a porous ceramic piece, but is not limited thereto.

[0065] In some embodiments of the present application, referring to Figures 2 to 7 The atomization support 300 is provided with a containing cavity in communication with the lower oil hole 310. The electronic atomization device further includes an air passage piece 500 arranged in the containing cavity. The air passage piece 500 is located on the side of the heating body 210 away from the lower oil hole 310. The side of the air passage piece 500 close to the heating body 210 is provided with a channel 510 in communication with the atomization channel 121.

[0066] Specifically, the heating body 210 and the liquid guide 400 are arranged in the containing cavity of the atomization support 300, and the liquid guide 400 is opposite to the lower oil hole 310. The channel 510 is a groove on the air passage piece 500, and one end of the channel 510 is in communication with the atomization channel 121. That is, the heating body 210 is located between the liquid guide 400 and the air passage piece 500. When the electronic atomization device is in operation, the aerosol mist generated by the heating body 210 heating the atomization liquid can flow along the aforementioned channel 510 to the atomization channel 121 and finally to the suction nozzle for the user to smoke.

[0067] In some embodiments of the present application, referring to Figures 2 to 7The side of the air passage piece 500 close to the heating body 210 is provided with a positioning column 520, and the heating body 210 is provided with a positioning hole 213 corresponding to the position of the positioning column 520, which is used for cooperating with the positioning column 520. Because the outer peripheral wall of the air passage piece 500 abuts against the inner wall of the oil cup body 110, the relative position of the air passage piece 500 and the oil cup body 110 can be fixed. By arranging the positioning column 520 on the air passage piece 500, the relative position of the heating body 210 can be relatively fixed, so that the supporting part 212 of the heating body 210 can keep the relative position with the oil outlet hole 310, thereby ensuring the heating temperature of the heating body 210 to the atomized liquid, which is beneficial to reducing the situation that the aerosol mist loses the taste after the user smokes for a period of time due to the too fast volatilization of the flavoring substances (such as lipid substances) in the atomized liquid (or tobacco tar) caused by the too high heating temperature, thereby helping to optimize the user experience.

[0068] In a possible implementation, the air passage piece 500 is made of silica gel.

[0069] In some embodiments of the present application, please continue to refer to Figures 2 to 7 The inner wall of the positioning hole 213 is provided with a protruding structure 214, which is used for cooperating with the positioning column 520. The arrangement of the protruding structure 214 makes the positioning column 520 keep extruding the protruding structure 214, which can reduce the situation that the positioning column 520 and the positioning hole 213 are loose. Compared with directly matching the profile of the positioning hole 213 with the outer peripheral profile of the positioning column 520, the present application can reduce the assembly resistance of the positioning column 520 inserted into the positioning hole 213 while ensuring that the positioning column 520 keeps extruding the protruding structure 214, which can facilitate assembly and can also avoid damage of the heating body 210 caused by too large assembly resistance during assembly.

[0070] In a possible implementation, please refer to Figures 3 to 5 The positioning column 520 is arranged in the positioning hole 213, and the side of the positioning column 520 close to the liquid storage cavity 130 abuts against the hole wall of the positioning hole 213, that is, the heating body 210 cannot move away from the atomization cavity. As shown in Figure 4 The side of the heating body 210 close to the liquid storage cavity 130 abuts against the inner wall of the atomization support 300, that is, the heating body 210 cannot continue to move close to the liquid storage cavity 130. In this way, the installation position of the heating body 210 is relatively fixed, which can prevent the heating body 210 from falling off, thereby reducing the situation that the relative position of the heating body 210 and the oil outlet hole 310 deviates due to non-assembly factors, and helping to ensure that the supporting part 212 of the heating body 210 keeps the position limitation of partially overlapping with the oil outlet hole 310, thereby being beneficial to slowing down the too fast volatilization of the flavoring substances in the atomized liquid.

[0071] In the above embodiments, the protruding structure 214 is in the form of a sawtooth.

[0072] In some other embodiments of the present application, the protruding structure 214 is integrally formed on the elastic arm of the heat-generating body 210, and the elastic arm is used to fixedly connect with the positioning column 520, that is, the heat-generating body 210 can be kept on the airway piece 500 by the elastic force.

[0073] Of course, the protruding structure 214 can also be a protruding dot, a cone or other shapes arranged on the inner wall of the positioning hole 213, which is not limited here, as long as the positioning column 520 can be fixed when the positioning hole 213 and the positioning column 520 are positioned.

[0074] In some embodiments of the present application, referring to Figure 5 , the heat-generating part 211 includes a plurality of heat-generating units arranged in sequence, and the heating areas of each heat-generating unit jointly form the heat-generating part 211 of the heat-generating body 210. As an example, the plurality of heat-generating units can be arranged in parallel or in series, and the shape of the heat-generating unit can be, but is not limited to, a prismatic shape, a rectangular shape, a triangular shape, an S shape, a mesh shape or other shapes.

[0075] In some embodiments of the present application, referring to Figures 5 to 7 , the support part 212 includes a plurality of support columns, one end of each support column is connected with the heat-generating unit, and the other end extends away from the heat-generating unit, and at least part of the plurality of support parts 212 overlaps with the oil outlet hole 310.

[0076] In the embodiments of the present application, referring to Figures 5 to 8 , the heat-generating part 211 is provided with a plurality of support parts 212 on both sides along the first direction, and the plurality of support columns on each side are arranged at intervals along the second direction of the heat-generating part 211, wherein the second direction intersects the first direction; the atomization support 300 is provided with at least two oil outlet holes 310 arranged at intervals along the first direction, wherein the at least two oil outlet holes respectively overlap with at least part of the plurality of support columns on both sides of the heat-generating part 211.

[0077] In some specific embodiments, the first direction can be parallel to the extension direction of the channel 510, of course, the second direction can also be parallel to the extension direction of the channel 510.

[0078] In some specific examples, the first direction and the second direction are perpendicular, the atomization support 300 is provided with two oil outlet holes 310 arranged at intervals along the first direction, each oil outlet hole 310 extends along the second direction, and the plurality of support columns on each side of the heat-generating part 211 overlap with the corresponding oil outlet hole 310, as shown in Figure 8 .

[0079] In some embodiments, the support column can extend partially to a position opposite to the outlet end of the oil outlet hole 310, and the support column can be arranged across the oil outlet hole 310, as shown in Figure 9 and Figure 10 Thus, when the heating body 210 is clamped between the oil guide body 400 and the atomization support 300, the problem that the heating body 210 is deformed due to the part of the support column not crossing the oil outlet hole 310 being pressed into the oil outlet hole 310 is reduced.

[0080] In some specific examples, the atomization support 300 is provided with a plurality of oil outlet holes 310, and the plurality of oil outlet holes 310 are arranged one-to-one corresponding to the plurality of support columns, as shown in Figure 10 .

[0081] It can be understood that the support column can also not be arranged across the oil outlet hole 310, as shown in Figure 8 .

[0082] Each support part 212 is provided with an oil outlet hole 310 corresponding to it, which helps to uniformly guide the atomization liquid to the heating body 210.

[0083] In some embodiments of the present application, referring to Figure 3 , the electronic atomization device further comprises a base 600, the base 600 is connected with the bottom of the oil cup 100, and the base 600 is provided with an air inlet channel 610, the air inlet channel 610 is in communication with the atomization channel 121. Specifically, one end of the groove 510 of the air duct 500 is in communication with the atomization channel 121, and the other end is in communication with the air inlet channel 610. During the suction process, the external airflow flows into the air inlet channel 610 and continues to flow towards the side of the suction nozzle along the groove 510, while driving the heating body 210 to heat the aerosol mist generated by atomization to flow to the atomization channel 121 and the suction nozzle.

[0084] In some embodiments of the present application, referring to Figure 2 and Figure 3 , the electronic atomization device further comprises an oil absorption cotton 700, the oil absorption cotton 700 is arranged on the base 600 and located on the side of the base 600 close to the heating body 210. Specifically, the oil absorption cotton 700 is provided with a relief hole corresponding to the position of the air inlet channel 610, the relief hole is used to facilitate the external airflow to flow into the inside of the electronic atomization device from the air inlet channel 610. Among them, the oil absorption cotton 700 can absorb the condensate formed in the atomization channel 121 or the atomization liquid leaked from the liquid storage cavity 130.

[0085] In an embodiment of the present application, referring to Figure 1 and Figure 2The electronic atomization device further comprises a first sealing member 1 and a second sealing member 2. The first sealing member 1 is configured to cooperate with the atomization channel 121 to block the atomization channel 121 when the electronic atomization device is not in use. The second sealing member 2 is configured to cooperate with the air inlet channel 610 to block the air inlet channel 610 when the electronic atomization device is not in use.

[0086] In an embodiment of the present application, the electronic atomization device further comprises a power supply assembly and an electrode column. The power supply assembly is electrically connected to the heating element 210 through the electrode column 800.
