[0030] Figures 1 to 4 The accompanying drawings of the present application.

[0031] The present embodiment provides an electronic atomization device, please refer to Figure 1 , 2 , including the shell 10, the first oil cup 20, the second oil cup 30 arranged in the shell 10, the mounting bracket 40 arranged at the bottom of the shell 10, the circuit board 50 arranged in the mounting bracket 40, and the battery 60 arranged in the shell 10. The first oil cup 20 and the second oil cup 30 are sequentially stacked, that is, the lower end of the first oil cup 20 and the upper end of the second oil cup 30 are connected to each other. One end of the shell 10 is provided with a suction nozzle 11, one end of the suction nozzle 11 is the upper end of the device, the other end is the lower end, and the lower end is provided with an air inlet end.

[0032] The first oil cup 20 is arranged close to the side of the suction nozzle 11 of the shell 10, and the second oil cup 30 is arranged away from the side of the suction nozzle 11. The mounting rack 40 is arranged below the second oil cup 30 and is fixedly connected with the second oil cup 30. The accommodating cavity 12 is arranged between the mounting rack 40 and the lower end of the second oil cup 30. The connection between the mounting rack 40 and the second oil cup 30 is a sealed connection, and the accommodating cavity 12 is a relatively sealed space. The accommodating cavity 12 also serves as an air inlet cavity. Air flows from the accommodating cavity 12, enters the second oil cup 30 and the first oil cup 20, and then is discharged from the suction nozzle 11. Because the first oil cup 20 and the second oil cup 30 are arranged in a stacked manner, the accommodating cavity 12 is located below the first oil cup 20 and the second oil cup 30, so that the condensed liquid generated during the operation of the first oil cup 20 and the second oil cup 30 can flow into the accommodating cavity 12; or, the first oil cup 20 and the second oil cup 30 may have a phenomenon of leakage of the atomized substrate, and the leaked atomized substrate can directly flow into the accommodating cavity 12. Because the first oil cup 20 and the second oil cup 30 are arranged in a stacked manner, the positions at which the heating elements in the two oil cups are installed have a certain distance, and the atomization channel is relatively long, so that the generation of condensed liquid is intensified during the operation of the first oil cup 20 and the second oil cup 30. Therefore, the accommodating cavity 12 can accommodate the condensed liquid to prevent it from flowing out of the shell 10. In addition, because the first oil cup 20 and the second oil cup 30 are both provided with heating elements, the heating elements need to be in communication with the atomized substrate in the oil cup, which increases the risk of leakage of the atomized substrate of the first oil cup 20 and the second oil cup 30. The accommodating cavity 12 is arranged below the second oil cup 30, and generally, the device is placed vertically, so that the accommodating cavity 12 has the function of buffering the leaked atomized substrate.

[0033] Please refer to Figure 1 、 2 The first oil cup 20 is provided with a first atomization channel 21, and the second oil cup 30 is provided with a second atomization channel 31. The first atomization channel 21 penetrates through the first oil cup 20, the upper end of which is in communication with the suction nozzle 11, and the lower end of which is in communication with the second atomization channel 31. The upper end of the second atomization channel 31 is in communication with the first atomization channel 21, and the lower end of the second atomization channel 31 is in communication with the accommodating cavity 12. Gas flows into the accommodating cavity 12, then enters the second atomization channel 31, and then flows to the suction nozzle 11 from the first atomization channel 21. The first oil cup 20 and the second oil cup 30 are arranged in a stacked manner, and the first atomization channel 21 and the second atomization channel 31 are in communication with each other, so that the aerosol formed by heating the atomized substrate of the first oil cup 20 and the aerosol formed by heating the atomized substrate of the second oil cup 30 are mixed in the first atomization channel 21.

[0034] Preferably, the first atomization channel 21 and the second atomization channel 31 are concentrically arranged to form a straight channel, which avoids excessive condensate of aerosol formed by the heated atomization substrate, and the concentric arrangement of the first atomization channel 21 and the second atomization channel 31 also enables the condensate and leaked atomization substrate to quickly flow into the containing cavity 12, preventing the condensate or leaked atomization substrate from remaining in the inner wall of the atomization channel. The lower end of the second atomization channel 31 communicates with the containing cavity 12, enabling the condensate and leaked oil to directly flow into the containing cavity 12.

[0035] Preferably, the containing cavity 12 is provided with an oil absorption cotton 13 below the second atomization channel 31, which is used to absorb the condensate and leaked oil flowing into the containing cavity 12, avoiding the condensate and leaked oil flowing to the outside of the shell 10.

[0036] Please refer to Figure 1 、 2 , the circuit board 50 is arranged on the opposite side of the mounting bracket 40 relative to the containing cavity 12, i.e. the circuit board 50 is arranged on the lower side of the mounting bracket 40, so that the circuit board 50 is in an isolated state from the containing cavity 12, avoiding the circuit board 50 being contaminated by the condensate or atomization substrate. The circuit board 50 is provided with an airflow sensor 51, and the sensing end of the airflow sensor 51 communicates with the containing cavity 12. Since the mounting bracket 40 and the second oil cup 30 are in a sealed state, and the containing cavity 12 is also in a sealed state, air needs to flow from the containing cavity 12 into the second atomization channel 31 and the first atomization channel 21, so the sensing end of the airflow sensor 51 communicates with the containing cavity 12, and the airflow sensor 51 can timely sense the flow of gas, and the signal triggered by the airflow sensor 51 is used to start the device.

[0037] The containing cavity 12 is provided with an air inlet hole 121 which communicates with the air inlet end of the shell 10. The lower end of the shell 10 is provided with an air inlet end which communicates with the containing cavity 12 through an air pipe to form the air inlet hole 121.

[0038] Preferably, the air inlet hole 121 and the lower end of the second atomization channel 31 are staggered with each other, so that the condensate or leaked oil flowing down from the second atomization channel 31 can flow in the containing cavity 12, and also enables to increase the airflow flow path, thereby improving the sensitivity of the airflow sensor 51. Specifically, the lower end of the second atomization channel 31 is located at one end of the containing cavity 12, and the air inlet hole 121 is located in the region between the middle to the other end of the containing cavity 12.

[0039] Preferably, the air inlet hole 121 protrudes from the bottom of the containing cavity 12 at one end of the containing cavity 12, preventing the condensate or leaked atomization substrate flowing into the containing cavity 12 from flowing out of the air inlet hole 121.

[0040] Please refer to Figure 2 、 3The mounting rack 40 is provided with a protrusion 41 on one side of the accommodating cavity 12, and the protrusion 41 is provided with a through hole 42. The through hole 42 penetrates through both ends of the mounting rack 40. After the mounting rack 40, the second oil cup 30 and the circuit board 50 are assembled, one end of the through hole 42 is in communication with the accommodating cavity 12, and the other end is in communication with the sensing end of the airflow sensor 51. The protrusion 41 is higher than the bottom of the accommodating cavity 12, so that after the condensate or leaked oil flows into the accommodating cavity 12, it is prevented from flowing back to the sensing end of the airflow sensor 51 from the through hole 42. The oil absorption cotton 13 arranged in the accommodating cavity 12 is higher than the upper surface of the oil absorption cotton 13. Preferably, the distance between the end of the protrusion 41 and the upper surface of the oil absorption cotton 13 is 0.5-3mm.

[0041] The protrusion 41 of the mounting rack 40 is also staggered with the lower end of the second atomization channel 31, preventing the condensate or leaked atomization medium in the second atomization channel 31 from polluting the sensing end of the airflow sensor 51.

[0042] Please refer to Figure 1 、 2 , 4, a connecting piece 14 is arranged between the first oil cup 20 and the second oil cup 30. One end of the connecting piece 14 is connected with the lower end of the first oil cup 20, and the other end is connected with the upper end of the second oil cup 30. The connecting piece 14 is provided with a connecting hole 141 for connecting the first atomization channel 21 and the second atomization channel 31. The connecting piece 14 not only connects the first oil cup 20 and the second oil cup 30, but also serves as a sealing member of the first oil cup 20 and the second oil cup 30, which is a component with multiple functions, reducing the number of components of the device. Preferably, the connecting piece 14 is made of silica gel, rubber or the like, which can not only be used as a connecting component, but also can seal the components of the first oil cup 20 and the second oil cup 30. The lower end of the heating element of the first oil cup 20 is fixed on the connecting piece 14. Specifically, the lower end of the heating element is fixedly connected with the connecting hole 141, so that air can enter the second atomization channel 31 from the connecting hole 141, thereby carrying away the atomized medium heated by the heating element into aerosol.

[0043] Specifically, please refer to Figure 1 、 4 , the connecting piece 14 includes a first connecting part 142 and a second connecting part 143. The connecting hole 141 penetrates through the first connecting part 142 and the second connecting part 143. The first connecting part 142 is connected with the lower end of the first oil cup 20, which not only plays a connecting role, but also serves as a sealing member of the lower end of the first oil cup 20. The first connecting part 142 serves as one of the components of the first oil cup 20, which can effectively reduce the number of components. The second connecting part 143 is connected to the upper end of the second oil cup 30, and has the same function as the first connecting part 142.

[0044] Specifically, please refer to Figure 1 、 2The first oil cup 20 comprises a first cup shell 201, an upper cover 202 arranged at an upper end of the first cup shell 201, and a first oil storage cotton 203 arranged in the first cup shell 201. The first connecting portion 142 of the connecting member 14 is arranged at a lower end of the first cup shell 201 and is in a sealed connection with the first cup shell 201. The first atomization channel 21 penetrates through the first oil storage cotton 203 and has one end located on the upper cover 202 and the other end located on the connecting hole 141 of the connecting member 14. The first atomization channel 21 is provided with a first heating member 204 for heating and atomizing the atomization substrate in the first oil cup 20.

[0045] Please refer to Figure 1 、 2 The second oil cup 30 comprises a second cup shell 301 and a second oil storage cotton 302 arranged in the second cup shell 301. The second cup shell 301 has a barrel structure and is provided with an air inlet 303 at a lower end. The second connecting portion 143 of the connecting member 14 is arranged at an upper end of the second cup shell 301, and the second atomization channel 31 penetrates through the second oil storage cotton 302. One end of the second atomization channel 31 is in communication with the connecting hole 141 of the connecting member 14, and the other end is in communication with the air inlet 303. The lower end of the second cup shell 301 is provided with a recess, and the recess is downwardly open, so that the mounting frame 40 is arranged at the recess to form the accommodating cavity 12. The second atomization channel 31 is provided with a second heating member 305 for heating and atomizing the atomization substrate in the second oil cup 30.

[0046] The first heating member 204 and the second heating member 305 are controlled by the control module arranged on the circuit board 60. The first heating member 204 and the second heating member 305 can work independently or jointly to produce different taste requirements.

[0047] Please refer to Figure 1 、 2 The first cup shell 201 and the second cup shell 301 are connected to each other to enable the first oil cup 20 and the second oil cup 30 to be arranged in a stacked manner. Specifically, the lower end of the first cup shell 201 is provided with a buckle 205 extending towards the second cup shell 301. The upper end of the second cup shell 301 is provided with a clamping groove 304 matched with the buckle 205 to enable the first oil cup 20 and the second oil cup 30 to be connected to each other. The first oil cup 20 and the second oil cup 30 are installed to each other through the buckle 205 and the clamping groove 304, and the installation is quick.

[0048] Preferably, please refer to Figure 1 、 2, 4, the connecting piece 14 further comprises a clamping portion 144. The clamping portion 144 is arranged between the first connecting portion 142 and the second connecting portion 143. When the first cup shell 201 and the second cup shell 301 are connected with each other, the clamping portion 144 is located between the lower end of the first cup shell 201 and the upper end of the second cup shell 301, and the ends of the first cup shell 201 and the second cup shell 301 are extruded on the clamping portion 144, thereby improving the sealing of the connecting piece 14 on the first oil cup 20 and the second oil cup 30. Because the clamping portion 144 is extruded by the first cup shell 201 and the second cup shell 301, the installation position of the entire connecting piece 14 is determined, and the installation rigidity of the connecting piece 14 is improved. For example, when the lower end of the first heating piece 204 in the first oil cup 20 is fixedly connected with the connecting piece 14, the installation rigidity of the connecting piece 14 is sufficient, so that the shape of the first heating piece 204 after installation is not deviated.

[0049] The second cup shell 301 is provided with a boss 3011 outside, and the battery 60 is arranged on the boss 3011. Because the boss 3011 is arranged outside the second cup shell 301, the battery 60 is isolated from the containing cavity 12, so that the battery 60 is prevented from being polluted by the condensed liquid or the leaked atomized substrate.

[0050] Compared with the prior art, the utility model discloses the installation frame 40 arranged below the first oil cup 20 and the second oil cup 30 arranged in mutual superposition, and the containing cavity 12 is arranged between the installation frame 40. The first atomization passage 21 of the first oil cup 20 and the second atomization passage 31 of the second oil cup 30 are communicated with each other, and the lower end of the second atomization passage 31 is communicated with the containing cavity 12, so that the containing cavity 12 can collect the condensed liquid or the leaked atomized substrate of the first oil cup 20 and the second oil cup 30, and prevent the condensed liquid or the leaked atomized substrate from polluting other components.

[0051] The above only further illustrates the technical content of the utility model with examples, so that the reader is easier to understand, but does not represent that the embodiment of the utility model is limited to this, and any technical extension or re-creation made according to the utility model is protected by the utility model. The protection scope of the utility model is subject to the patent claim.
