[0027] Please refer to Figure 1 , which is a schematic structural diagram of the atomizer 10 in an embodiment.

[0028] The atomizer 10 is an aerosol generating device of an electronic atomization device, which is used to generate heat under the condition of being powered on, so that the e-liquid in the atomizer 10 forms an aerosol for the user to inhale.

[0029] Specifically, please refer to Figures 2 to 5, the atomizer 10 includes a housing 12, an atomization component 14 and a base 16. The housing 12 includes a mouthpiece end 121 and an open end, and the base 16 is inserted into the open end. The atomizer 10 further includes an oil-core separation component 18, which includes a movable partition sleeve 182 and a pull rod 184. The pull rod 184 is detachably arranged with the movable partition sleeve 182. The movable partition sleeve 182 divides the interior of the housing 12 into an oil storage chamber 122 and an atomization chamber 124. The atomization component 14 is arranged in the atomization chamber 124. The housing 12 is convexly provided with a positioning boss 126 in the direction of the atomization chamber 124, and the atomization chamber 124 is provided with an air outlet hole 1262 passing through the boss and communicating with the mouthpiece 121. One end of the movable partition sleeve 182 is inserted into the positioning boss 126, and the other end of the movable partition sleeve 182 is fixed to the base 16. The movable partition sleeve 182 is provided with an oil guiding hole 1822. The pull rod 184 drives the movable partition sleeve 182 to axially move along the positioning boss 126 to control the exposure or hiding of the oil guiding hole 1822 in the base 16, so that the atomization component 14 is communicated with or separated from the oil storage chamber 122 as the oil guiding hole 1822 is exposed or hidden.

[0030] The atomizer 10 is provided with a movable oil-core separation component 18 inside the housing 12, and the separation or conduction between the oil storage chamber 122 and the atomization component 14 can be controlled with the movement of the oil-core separation component 18. When the oil storage chamber 122 of the atomizer 10 is pre-filled with e-liquid, stored in a high-temperature environment or transported under low pressure, the oil-core separation component 18 can separate the atomization component 14 from the e-liquid in the oil storage chamber 122, and can prevent the e-liquid from leaking out through the atomization component 14 due to the increase in pressure in the oil storage chamber 122 or the decrease in external pressure. When the atomizer 10 needs to be used, the oil-core separation component 18 moves to control the conduction between the atomization component 14 and the oil storage chamber 122, and after the atomization component 14 is supplied with oil, high-temperature atomization can be carried out. The oil-core separation component 18 can effectively prevent the problem of oil leakage of the atomizer 10 during high-temperature storage and low-pressure transportation, improve the user experience, and has a simple structure and low cost. The pull rod 184 and the movable partition sleeve 182 are detachably arranged, and according to the use and storage requirements, the pull rod 184 can be used to push and pull the movable partition sleeve 182 repeatedly to realize the conduction and separation between the atomization component 14 and the oil storage chamber 122, which is convenient to operate and can be used repeatedly.

[0031] Among them, the atomization component 14 includes an oil guiding element, a heating element and a metal tube. After the oil guiding element is coated on the heating element, the oil guiding element and the heating element are integrally placed inside the metal tube. The metal tube is provided with a through hole, and the oil guiding element is communicated with the oil storage chamber 122 at the through hole and the oil guiding hole 1822, so that the e-liquid in the oil storage chamber 122 is guided out by the oil guiding element, and the heating element is energized to generate heat to atomize the e-liquid on the oil guiding element.

[0032] Please refer to Figure 4 , Figure 5, in this embodiment, the movable partition sleeve 182 is provided with a supporting protrusion 1824 and a receiving groove 1826 on the inner wall where the atomization chamber 124 is located. The supporting protrusion 1824 and the receiving groove 1826 are arranged at intervals. One end of the pull rod 184 is provided with a first abutting protrusion 1842, a second abutting protrusion 1844 and a clamping groove 1846, and the first abutting protrusion 1842 and the second abutting protrusion 1844 are arranged on both sides of the clamping groove 1846. When it is necessary to use the pull rod 184 to adjust the position and state of the movable partition sleeve 182, the pull rod 184 is inserted through the nozzle 121, so that the first abutting protrusion 1842 penetrates through the receiving groove 1826 and then the pull rod 184 is rotated, so that the supporting protrusion 1824 is received in the clamping groove 1846. After the first abutting protrusion 1842 and the second abutting protrusion 1844 are misaligned with the receiving groove 1826, they respectively abut against both sides of the supporting protrusion 1824. Pushing and pulling the pull rod 184 can make the movable partition sleeve 182 move along the positioning boss 126, so that the atomization assembly 14 is communicated with or separated from the oil storage chamber 122. Wherein, the shape of the first abutting protrusion 1842 is adapted to the receiving groove 1826, or the first abutting protrusion 1842 is smaller than the opening size of the receiving groove 1826, so that the first abutting protrusion 1842 can pass through the receiving groove 1826; the shape of the second abutting protrusion 1844 is not limited, and it can be smaller than the opening size of the receiving groove 1826, adapted to the receiving groove 1826, larger than the opening size of the receiving groove 1826, or even a circular boss arranged on the outer periphery of the pull rod 184. In the initial state, the atomization assembly 14 is separated from the oil storage chamber 122; when in use, the pull rod 184 is inserted into the movable partition sleeve 182, and the first abutting boss abuts against the supporting protrusion 1824. The pull rod 184 is pulled in the direction of the nozzle 121. At this time, the first abutting boss pulls the supporting protrusion 1824 to drive the movable partition sleeve 182 to move towards the nozzle 121 end, exposing the oil guiding hole 1822, so that the atomization assembly 14 is communicated with the oil storage chamber 122; when not in use, the pull rod 184 is inserted into the movable partition sleeve 182, and the second abutting boss abuts against the supporting protrusion 1824. The pull rod 184 is pushed in the direction of the base 16. At this time, the second abutting boss pushes the supporting protrusion 1824 to drive the movable partition sleeve 182 to move towards the base 16 direction, hiding the oil guiding hole 1822, so that the atomization assembly 14 is separated from the oil storage chamber 122.

[0033] In another embodiment, the movable partition sleeve 182 is provided with an internal thread on the inner wall where the atomization chamber 124 is located, and one end of the pull rod 184 is provided with an external thread. After the internal thread and the external thread are screwed together, pushing and pulling the pull rod 184 makes the atomization assembly 14 communicate with or be separated from the oil storage chamber 122. When it is necessary to use the pull rod 184 to adjust the position of the movable partition sleeve, insert the pull rod 184 from the nozzle 121 and rotate and screw it, then the pull rod 184 can be fixed to the movable partition sleeve 182, and it can be pushed or pulled to drive the movable partition sleeve 182 to hide or expose the oil guiding hole 1822; after adjusting to the desired position, then rotate and unscrew the pull rod 184 from the movable partition sleeve 182.

[0034] Please refer to Figure 2 , in this embodiment, the housing 12 is provided with a lanyard hole 128, and the pull rod 184 is fixed to the lanyard hole 128 through a lanyard. The pull rod 184 and the movable partition sleeve 182 are detachably arranged. Setting the lanyard to fix the pull rod 184 to the housing 12 will not be lost when not in use, which is convenient for repeated use.

[0035] In another embodiment, the outer wall of the pull rod 184 is arranged along the smoke passage between the atomization channel and the nozzle 121, and the pull rod 184 is hollow. The hollow interior of the pull rod 184 communicates with the atomization chamber 124 to form an air outlet passage. At this time, the pull rod 184 can be used as a part of the nozzle 121 and is not disassembled from the movable partition sleeve 182, so there is no need to consider the problem of loss after the pull rod 184 is disassembled.

[0036] Please refer to Figure 4 、 Figure 5 , in this embodiment, the base 16 is provided with a receiving cavity 162. One end of the movable partition sleeve 182 is arranged in the receiving cavity 162. The movable partition sleeve 182 moves in the receiving cavity 162 to drive the oil guide hole 1822 to be exposed or hidden, so that the atomization assembly 14 is communicated with or separated from the oil storage cavity 122. The receiving cavity 162 is used to provide the space required for the movement of the movable partition sleeve 182, making the movement of the movable partition sleeve 182 smoother. At the same time, since the receiving cavity 162 is arranged at one end of the movable partition sleeve 182 and does not contact the oil storage cavity 122 and the atomization assembly 14, there will be no residual e-liquid in the receiving cavity 162. Moreover, since one end of the movable partition sleeve 182 is always in the receiving cavity 162 and the other end is always inserted into the positioning boss 126, the combination of the two can accurately control the movement track of the movable partition sleeve 182, making the movement of the movable partition sleeve 182 smoother, the control more accurate, and the oil separation and leakage prevention effect better.

[0037] Further, air flow holes 163 are provided on the side wall or bottom of the accommodation cavity 162. The air flow holes 163 communicate with the atomization cavity 124, and the air in the accommodation cavity 162 is discharged or air is replenished into the accommodation cavity 162 as the movable partition sleeve 182 axially moves. When the atomization assembly 14 is separated from the oil storage cavity 122, one end of the movable partition sleeve 182 is placed in the entire accommodation cavity 162. At this time, the air in the accommodation cavity 162 is discharged through the air flow holes 163, and the movable partition sleeve 182 is not affected by air resistance, making the movement of the movable partition sleeve 182 smoother. Moreover, since the air in the accommodation cavity 162 can be discharged through the air flow holes 163, there will be no situation where air is squeezed out through the gaps on both sides between the accommodation cavity 162 and the movable partition sleeve 182 without the air flow holes 163, and the air discharged into the oil storage cavity 122 squeezes the e-liquid or even accelerates e-liquid leakage, which is beneficial to maintaining the air pressure balance in the oil storage cavity 122 and avoiding e-liquid leakage. When the atomization assembly 14 is communicated with the oil storage cavity 122, one end of the movable partition sleeve 182 is removed from the accommodation cavity 162. At this time, if the air in the accommodation cavity 162 cannot replenish the air at the removed position, it will cause the air pressure in the accommodation cavity 162 to become smaller. On the one hand, it will require greater force for the movable partition sleeve 182 to move, and the movement will not be smooth. On the other hand, it will cause the e-liquid in the oil storage cavity 122, and even the e-liquid that originally flowed to the atomization assembly 14, to flow into the accommodation cavity 162 through the gaps on both sides between the accommodation cavity 162 and the movable partition sleeve 182, affecting the e-liquid absorption of the atomization assembly 14. When the atomization assembly 14 and the oil storage cavity 122 are separated again, the e-liquid in the accommodation cavity 162 will hinder the movement of the movable partition sleeve 182. When using greater force to make the movable partition sleeve 182 continue to move, the e-liquid in the accommodation cavity 162 will be squeezed out into the oil storage cavity 122 or even the atomization assembly 14. If it cannot be absorbed by the atomization assembly 14, it will cause e-liquid leakage. The air flow holes 163 provided in the accommodation cavity 162 can avoid the occurrence of these problems. During the process of one end of the movable partition sleeve 182 being removed from the accommodation cavity 162, external air can enter the accommodation cavity 162 through the air flow holes 163, making the movement of the movable partition sleeve 182 smooth and not disrupting the balance between the e-liquid and the air.

[0038] Furthermore, the outer wall surface of the movable separation sleeve 182 from the oil guide hole 1822 to the middle is set as a truncated cone or quasi-truncated cone shaped rib plate; when the movable separation sleeve 182 moves with the push and pull of the pull rod 184, the truncated cone or quasi-truncated cone shaped rib plate will change the volume of the oil storage chamber 122 accordingly. When the movable separation sleeve 182 is in the state of separating the oil storage chamber 122 and the atomizer assembly 14, the truncated cone or quasi-truncated cone shaped rib plate moves to contact with the base 16 or even partially embedded in the base 16. At this time, the volume occupied by the movable separation sleeve 182 is reduced, the volume of the oil storage chamber 122 is increased, the air pressure is reduced, and the pressure on the smoke oil is also reduced, which is conducive to slowing down the leakage of the smoke oil during the separation. When the movable separation sleeve 182 is in the state of connecting the oil storage chamber 122 and the atomizer assembly 14, the frustum or quasi-frustum-shaped rib plate moves away from the base 16. At this time, the volume occupied by the movable separation sleeve 182 increases, the volume of the oil storage chamber 122 decreases, the air pressure increases, and the pressure on the oil also increases accordingly, which is beneficial to speed up the extraction of the oil into the atomizer assembly 14, so that the atomizer assembly 14 can quickly absorb the oil and prepare for heating and atomization, avoiding the atomizer assembly 14 from burning due to insufficient oil.

[0039] In this embodiment, a seal 186 is provided between the movable separation sleeve 182 and the positioning boss 126. The seal 186 is fixed to the end of the movable separation sleeve 182 and moves with the movable separation sleeve 182. The seal 186 moves with the movable separation sleeve 182, and can always maintain a good fit between the seal 186 and the movable separation sleeve 182, so that the seal 186 and the movable separation sleeve 182 will not be damaged due to the movement, which is conducive to maintaining a good sealing performance between the movable separation sleeve 182 and the positioning boss 126.

[0040] Furthermore, the base 16 includes a sealing seat 164 and a bottom cover 166. The sealing seat 164 is inserted into the open end and seals the oil storage cavity 122. The bottom cover 166 is covered on the open end, and a liquid storage cavity 168 is provided between the sealing seat 164 and the bottom cover 166. The accommodating cavity 162 is provided on the sealing seat 164. The sealing seat 164 plays a sealing role and can perfectly seal the gap between the oil storage cavity 122 and the base 16 and the movable partition assembly to avoid oil leakage. The liquid storage cavity 168 between the sealing seat 164 and the bottom cover 166 can be used to gather the condensate generated by the atomizer 10 heating and atomization to prevent the condensate or the smoke oil from being sucked into the user's mouth, affecting the smoking taste, or the condensate leaking through the air inlet of the base 16, affecting the service life of the battery host 20.

[0041] An electronic atomization device includes an atomizer 10 and a battery main unit 20, and the battery main unit 20 is adapted to the atomizer 10. For the specific structure of the atomizer 10, refer to the above-mentioned embodiments. Since this electronic atomization device adopts all the technical solutions of the above-mentioned all embodiments, it has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, and will not be elaborated one by one here.
