[0032] Reference Figures 1 to 6 According to an embodiment of the present application, the electronic atomization device includes an atomizer 100, a power supply device 200 and an oil storage bottle 300.

[0033] Specifically, the atomizer 100 includes an oil cup 110 and an atomizer core 120 arranged inside the oil cup 110. The interior of the oil cup 110 has a liquid storage chamber 111 for supplying atomized liquid to the atomizer core 120. At least part of the physical structure of the oil cup 110 is configured as a transparent structure for observing the liquid level of the atomized liquid in the liquid storage chamber 111. The power supply device 200 is electrically connected to the atomizer 100, and the power supply device 200 is used to supply power to the atomizer 100. The oil storage bottle 300 is connected to the atomizer 100, and the oil storage bottle 300 is used to replenish the atomized liquid to the liquid storage chamber 111.

[0034] During use, since at least part of the physical structure of the oil cup 110 is configured as a transparent structure for observing the liquid level of the atomized liquid in the liquid storage chamber 111 of the atomizer 100, the user can know the remaining amount of the atomized liquid in the liquid storage chamber 111 of the atomizer 100 in real time, so that the atomized liquid in the oil storage bottle 300 can be replenished into the liquid storage chamber 111 of the atomizer 100 in time, which is beneficial to prevent the atomizer core 120 from dry burning and producing a burnt smell due to insufficient oil supply, thereby helping to improve the user experience.

[0035] It should be noted that in some of the embodiments, the entire physical structure of the oil cup 110 is a transparent structure, which can reduce the difficulty of processing and help control costs compared to the case where only part of the physical structure is a transparent structure.

[0036] It should be noted that in some embodiments, the power supply device 200 is detachably connected to the atomizer 100, the power supply device 200 has an exposed first electrical connection portion 210, the atomizer 100 has an exposed second electrical connection portion 130, and the first electrical connection portion 210 and the second electrical connection portion 130 abut against each other. Since the power supply device 200 and the atomizer 100 are detachably connected, compared with the case where the power supply device 200 and the atomizer 100 are fixedly arranged as one body, when the power supply device 200 is damaged, only the power supply device 200 needs to be replaced, and when the atomizer 100 is damaged, only the atomizer 100 needs to be replaced, and there is no need to repurchase the electronic atomization device, which is conducive to reducing the user's use cost.

[0037] It should be noted that, in some embodiments, the oil storage bottle 300 is detachably connected to the atomizer 100. On the one hand, when the atomized liquid in the oil storage bottle 300 is used up, the oil storage bottle 300 can be removed to replenish the atomized liquid; on the other hand, the atomizer 100 and the oil storage bottle 300 can be replaced at the same time to change the flavor, so as to meet the user's needs for switching different flavors.

[0038] Reference Figures 2 to 4In some embodiments, the oil storage bottle 300 is connected to one end of the atomizer 100 and has an open bottle mouth, the oil cup 110 is provided with an oil supply channel 151 inside, one end of the oil supply channel 151 is connected to the liquid storage chamber 111, the atomizer 100 is provided with a threaded connection hole 141 connected to the other end of the oil supply channel 151, and the oil storage bottle 300 has one end of the bottle mouth threadedly connected to the threaded connection hole 141, which has a simple structure and is easy to implement.

[0039] Specifically, the oil cup 110 is a bottom opening structure, a bottom cover 140 is provided at the bottom opening of the oil cup 110, a threaded connection hole 141 is provided on the bottom cover 140 and passes through the bottom cover 140, a seal 150 is provided between the bottom cover 140 and the oil cup 110, and an oil supply channel 151 is formed on the seal 150.

[0040] It should be noted that, in some other embodiments, the oil supply channel 151 may also be formed in a physical structure inside the oil cup 110 , which is not limited here.

[0041] Reference Figures 2 to 6 In some embodiments, the power supply device 200 has a first extension portion 220, the first extension portion 220 has an avoidance through hole 221, the oil storage bottle 300 has an end of the bottle mouth that is inserted into the avoidance through hole 221, the oil storage bottle 300 has a raised limiting portion 310, and the first extension portion 220 is sandwiched between the limiting portion 310 and the atomizer 100. In the related art, in order to be able to replace the atomizer 100, the atomizer 100 and the power supply device 200 are generally detachably connected through a magnetic structure, which, on the one hand, makes the assembly structure more complicated and increases the cost; on the other hand, makes the connection relationship between the atomizer 100 and the power supply device 200 unstable and easy to detach from each other. The above structure connects the atomizer 100 and the power supply device 200 through the oil storage bottle 300, which is conducive to simplifying the assembly structure and enhancing the stability and reliability of the connection relationship between the atomizer 100 and the power supply device 200.

[0042] Reference Figure 3 In some embodiments, the oil storage bottle 300 is vertically arranged, and one end of the oil storage bottle 300 having a bottle mouth is located at the top of the oil storage bottle 300. In the axial direction of the oil storage bottle 300, the end of the oil supply channel 151 close to the oil storage bottle 300 is lower than the end of the oil supply channel 151 close to the liquid storage chamber 111, and the end of the oil supply channel 151 close to the liquid storage chamber 111 is higher than the highest liquid level of the liquid storage chamber 111, so that when the user uses the electronic atomization device normally, the atomized liquid in the liquid storage chamber 111 will not flow back into the oil supply channel 151 and the oil storage bottle 300.

[0043] It should be noted that, in some other embodiments, a switch valve that can be opened or closed by the user can also be provided in the oil supply channel 151 or at the bottle mouth of the oil storage bottle 300, and the on-off of the flow path between the oil storage bottle 300 and the liquid storage chamber 111 can be controlled by the switch valve. At this time, there is no need to limit the posture of the oil storage bottle 300 and the height of the two ends of the oil supply channel 151, and no limitation is made here.

[0044] It should be noted that, in some of the embodiments, the electronic atomization device also includes a detachable sealing structure, which is used to seal one end of the oil supply channel 151 close to the threaded connection hole 141, so that the electronic atomization device can be equipped with an oil storage bottle 300 or not. When the user does not choose the oil storage bottle 300, the end of the oil supply channel 151 close to the threaded connection hole 141 can be sealed by the sealing structure, thereby enriching the user's choices.

[0045] Reference Figure 4 and Figure 6 In some embodiments, the blocking structure includes a plug 400 that can pass through the avoidance through hole 221 and be threadedly connected to the threaded connection hole 141. One end of the plug 400 is provided with an elastic sealing portion 410 for inserting into the oil supply channel 151 and having an interference fit with the oil supply channel 151. The structure is simple and easy to implement. Specifically, the elastic sealing portion 410 is a silicone member or a rubber member embedded in the plug 400, which is not limited here.

[0046] Reference Figure 4 and Figure 6 In some embodiments, a twisting portion 420 for applying force is provided at one end of the plug 400 away from the elastic sealing portion 410, so that the user can apply force through the twisting portion 420 and drive the plug 400 to rotate to install or remove the plug 400.

[0047] It should be noted that, in some other embodiments, the plug 400 may also be a silicone or rubber part that can be inserted into the threaded connection hole 141 and has an interference fit with the threaded connection hole 141. In this case, the plug 400 does not need to be threadedly connected to the threaded connection hole 141, and this is not limited here.

[0048] It should be noted that, in some other embodiments, the end of the oil storage bottle 300 having the bottle mouth can also be threadedly connected to the end of the oil supply channel 151 away from the liquid storage chamber 111. Correspondingly, the threaded connection hole 141 can be replaced by an ordinary through hole, which is not limited here.

[0049] It should be noted that, in some of the embodiments, the volume of the oil storage bottle 300 is greater than the volume of the liquid storage chamber 111, so that the user does not need to frequently disassemble the oil storage bottle 300 to replenish the atomized liquid, which is conducive to improving the user experience.

[0050] Reference Figures 1 to 6 In some embodiments, the electronic atomization device further includes an outer cover 500, the oil storage bottle 300 and the outer cover 500 are located on the same side of the power supply device 200, the outer cover 500 is arranged outside the oil storage bottle 300 to cover the oil storage bottle 300, and one end of the outer cover 500 is rotatably connected to the atomizer 100 or the power supply device 200, so that the outer cover 500 can be rotated to expose the oil storage bottle 300. When the user does not need to remove the oil storage bottle 300, the outer cover 500 can cover the oil storage bottle 300. On the one hand, it can hide and protect the oil storage bottle 300, which is conducive to preventing children from removing the oil storage bottle 300 without supervision, resulting in leakage of the atomized liquid or accidental ingestion of the atomized liquid; on the other hand, it is conducive to improving the aesthetics of the electronic atomization device. When the user needs to remove the oil storage bottle 300, just rotate and open the outer cover 500, which has a simple structure and is easy to operate.

[0051] Reference Figure 1 , Figure 5 and Figure 6 In some of the embodiments, one end of the outer cover 500 is rotatably connected to the first extension portion 220. Of course, the outer cover 500 can also be rotatably connected to the atomizer 100, which is not limited here.

[0052] It should be noted that in some of the embodiments, a snap-fit ​​structure that can release the snap-fit ​​state is provided between the outer cover 500 and the power supply device 200. The snap-fit ​​structure is used to limit the outer cover 500 that is arranged outside the oil storage bottle 300 and covers the oil storage bottle 300 from rotating and opening. This can improve the stability and reliability of the outer cover 500 during operation, and is beneficial to preventing the outer cover 500 from accidentally opening when the user uses the electronic atomization device, and is also beneficial to preventing the outer cover 500 from being accidentally opened by unsupervised children.

[0053] Reference Figure 1 , Figure 5 and Figure 6 In some embodiments, a second extension portion 510 is provided on one side of the outer cover 500 close to the power supply device 200, a recessed portion 230 cooperating with the second extension portion 510 is provided on the power supply device 200, and a snap-fit ​​structure is provided between the second extension portion 510 and the recessed portion 230.

Of course, the snap-fit ​​block can also be arranged on the second extension portion 510, and correspondingly, the snap-fit ​​slot is arranged on the recessed portion 230, which is not limited here. In addition, the above-mentioned snap-fit ​​structure, as a conventional structure in the mechanical field, can also be implemented in other ways, which are not limited here.
