[0033] Please combine Figure 1 、 Figure 2 and Figure 3The first embodiment of the present invention provides an electronic atomizer 1, including a shell, which includes an oil cup shell 11, a connector 12 and a bottom cover 13 connected in sequence. The connector 12 is provided with an energy storage component 120 and a first circuit board 121 and a second circuit board 122 located on the upper and lower sides of the energy storage component 120, respectively. The first circuit board 121 and the second circuit board 122 are respectively provided with a first through hole 1210 and a second through hole 1220. The connector 12 is provided with a partition 123, and the partition 123 is provided with a pipe 124 connecting the first through hole 1210 and the second through hole 1220.

[0034] As can be understood, the energy storage element 120 provides power to the various electrical components within the electronic atomizer 1. The placement of two circuit boards, a first circuit board 121 and a second circuit board 122, on the upper and lower sides of the energy storage element 120 is based on optimized circuit wiring and considerations of the overall structure of the electronic atomizer 1. This design helps reduce unused space within the electronic atomizer 1, improving its miniaturization and portability while ensuring circuit stability and safety.

[0035] Specifically, in this embodiment, the first circuit board 121 is disposed on the upper side of the energy storage element 120, and the second circuit board 122 is disposed on the lower side of the energy storage element 120. The first circuit board 121 includes components such as a control circuit and an airflow detector. The control circuit is used to receive signals from the airflow detector and control the atomization process of the electronic atomizer 1. The second circuit board 122 is primarily responsible for charging, discharging, and safety protection of the energy storage element 120. This design enables better layout of internal circuits, rationally utilizes the internal space of the electronic atomizer 1, and improves the overall performance of the electronic atomizer 1.

[0036] It can be understood that, on the one hand, the connecting member 12 is used to connect the oil cup shell 11 and the bottom cover 13 to form a cavity for accommodating the energy storage member 120, the first circuit board 121 and the second circuit board 122. On the other hand, a partition 123 is provided inside the connecting portion. The partition 123 is not only used to set the pipeline 124, but also can be used to fix the first circuit board 121 and the second circuit board 122 and support the energy storage member 120.

[0037] Please further combine Figure 4 As can be understood, the first through-hole 1210 and the second through-hole 1220 serve as channels for introducing external airflow into the interior of the electronic atomizer 1. By providing a conduit 124 on the partition 123, connecting the first through-hole 1210 and the second through-hole 1220, the external airflow can be isolated within the conduit 124, preventing it from corroding, contaminating, or damaging the first and second circuit boards 121, 122. Furthermore, when the electronic atomizer 1 is in operation, the conduit 124 can also isolate condensation formed inside, preventing faults such as short circuits between the first and second circuit boards 121, 122, thereby effectively improving the overall structural stability and safety of the electronic atomizer 1.

[0038] In this embodiment, the connection method between the oil cup housing 11, the connector 12, and the bottom cover 13 is not specifically limited and can be any detachable connection method such as a snap connection or a threaded connection. It is understood that to enhance the reliability of the connection and the sealing of the electronic atomizer 1, suitable sealing ribs can be further provided between the oil cup housing 11, the connector 12, and the bottom cover 13.

[0039] Please further combine Figure 5 An airway plate 125 is provided in the shell near the bottom cover 13. The airway plate 125 is provided with a connecting groove 1250 and at least two air inlet holes 1251. The connecting groove 1250 is provided on a side away from the bottom cover 13 and connects multiple air inlet holes 1251.

[0040] It is understandable that the multiple air inlet holes 1251 on the airway plate 125 can be set to different diameters. The user can choose to use different air inlet holes 1251 to intake air, so as to flexibly control the amount of smoke from the electronic atomizer 1, thereby improving the user experience.

[0041] Please further combine Figure 6 The electronic atomizer 1 includes an atomizing device 14 , an air flow channel 140 is provided in the middle of the atomizing device 14 , a first through hole 1210 is connected to the air flow channel 140 of the atomizing device 14 , a second circuit board 122 is arranged on a side of the airway plate 125 away from the bottom cover 13 , and a second through hole 1220 is connected to the groove 1250 .

[0042] It can be understood that the airflow channel 140, the first through hole 1210, the pipe 124, the second through hole 1220, the connecting groove 1250 and the air inlet 1251 are connected in sequence to form a complete and reasonable airflow path, which can smoothly introduce the external airflow into the atomizing device 14, driving the generated aerosol to flow in the direction close to the oil cup shell 11.

[0043] Furthermore, the bottom cover 13 defines a sliding groove 130 , in which a toggle member 131 is slidably disposed. The toggle member 131 defines an opening 1310 corresponding to the air inlet hole 1251 .

[0044] It can be understood that the setting of the toggle member 131 makes it convenient for the user to select the appropriate air inlet 1251. At the same time, all the air inlet holes 1251 can be closed by the toggle member 131 when not in use to prevent misoperation and misstartup, thereby improving the reliability and safety of the device.

[0045] In this embodiment, the specific shape of the toggle member 131 is not limited. It only needs to cooperate with the bottom cover 13 and the airway plate 125 to select the appropriate air inlet hole 1251 for air intake or close all the air inlet holes 1251.

[0046] Please continue to combine Figure 2 and Figure 3 The atomizing device 14 includes a sleeve 141 , an oil storage cotton 142 and an atomizing core 143 arranged inside the sleeve 141 . The sleeve 141 has openings 113 at both ends, and a plurality of oil inlet holes 1410 are opened at the end near the connecting member 12 .

[0047] It can be understood that the sleeve 141 supports and fixes the internal components of the entire atomization device 14. The liquid to be atomized enters the sleeve 141 through the oil inlet hole 1410 and is absorbed and stored by the oil storage cotton 142 to continuously provide the atomization core 143 with the liquid to be atomized during the atomization process.

[0048] It can be understood that the oil inlet holes 1410 are set in multiple numbers and evenly distributed at the end of the sleeve 141 close to the connector 12, which can maximize the utilization rate of the liquid to be atomized and at the same time make sealing more convenient and reduce the risk of leakage.

[0049] Furthermore, one end of the oil cup shell 11 is connected to the connecting member 12, and the other end is formed with a mouthpiece 110 that is connected to the air flow channel 140. An upper seal 111 and a lower seal 112 are provided at both ends of the atomizer 14 in the oil cup shell 11. The upper seal 111 and the lower seal 112 are provided corresponding to the air flow channel 140 and both have openings 113.

[0050] As can be understood, the upper seal 111 and the lower seal 112 can effectively prevent liquid leakage from the oil cup housing 11, improving the safety and stability of the product. The opening 113 can ensure smooth inflow and outflow of air, forming a complete airflow path and improving the utilization and efficiency of the airflow.

[0051] Furthermore, a detachable sealing rod 114 is provided in the cigarette holder 110 , and one end of the sealing rod 114 extends into the cigarette holder 110 and abuts against the partition 123 along the air flow channel 140 .

[0052] As can be understood, the sealing rod 114 blocks the mouthpiece 110, effectively blocking external pressure fluctuations and reducing the self-priming phenomenon caused by pressure changes. At the same time, it enhances the sealing performance of the electronic atomizer 1, greatly reducing the risk of the internally stored liquid to be atomized from overflowing from the mouthpiece 110, and effectively avoiding the risk of oil leakage during transportation.

[0053] Furthermore, the housing, the upper sealing member 111 , the lower sealing member 112 and the atomizing device 14 enclose an oil storage chamber 115 , and an oil filling hole 116 is provided on one side of the oil cup shell 11 .

[0054] It can be understood that this design can realize two oil injection methods, namely, oil injection through the oil injection hole 116 or oil injection by piercing the lower sealing member 112 with an oil injection needle.

[0055] It can be understood that the oil filling process of piercing the lower seal 112 by using an oil filling needle specifically includes the following steps: first, disassemble the bottom cover 13 and the connector 12, and turn the remaining part of the electronic atomizer 1 upside down, that is, place the mouthpiece 110 facing downwards; then use the oil filling needle filled with the liquid to be atomized to pass through the lower seal 112 and pierce the oil storage cavity 115; before oil filling, the sealing rod 114 needs to be pulled outward along the mouthpiece 110 for a distance so that its bottom is in contact with the oil inlet hole 1410, and then the oil filling can be started; when the oil filling amount is about to reach the oil inlet hole 1410, the sealing rod 114 is inserted back into its original position for sealing, and the oil filling is continued until it is full and then the oil filling needle is removed.

[0056] As will be appreciated, the oil filling hole 116 needs to be sealed with a rubber plug when not in use. Specifically, in this embodiment, the oil cup housing 11 has a through hole formed near the oil filling hole 116. A fixing bolt is provided on the rubber plug corresponding to the through hole. The fixing bolt and the through hole cooperate to secure the rubber plug to the oil cup housing 11 and tightly seal the oil filling hole 116.

[0057] Please combine Figure 2 、 Figure 3 and Figure 6 An airflow space 15 is formed between the lower sealing member 112 and the partition 123 , and oil-absorbing cotton 16 is provided in the airflow space 15 close to the partition 123 .

[0058] It can be understood that the oil-absorbing cotton 16 acts as a protective layer to prevent the liquid to be atomized from overflowing or leaking, while effectively absorbing the condensate generated by atomization, thereby extending the service life of the entire equipment and reducing the need for frequent cleaning.

[0059] Furthermore, the thickness of the oil-absorbing cotton 16 is smaller than the height of the pipe 124 extending to the airflow space 15 .

[0060] It can be understood that after connecting the first through hole 1210 and the second through hole 1220, the pipe 124 continues to extend along the side of the partition 123 away from the first circuit board 121, that is, the pipe 124 continues to extend along the air flow space 15, and its extension height should be no less than the thickness of the oil-absorbing cotton 16, in order to effectively prevent the liquid to be atomized or condensate absorbed by the oil-absorbing cotton 16 from overflowing through the pipe 124, thereby affecting the user experience, and further improving the overall reliability and safety of the equipment.

[0061] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the principles of the present invention should be included in the scope of protection of the present invention.
