[0036] The present application provides an atomization device, which may include a housing, a partition, a sealing assembly, and a drive assembly. The housing may have a cavity formed therein; the partition may be disposed within the cavity and sealingly connected to the housing. The partition may divide the cavity into an oil storage chamber and an oil supply chamber, and the partition may extend through an oil passage connecting the oil storage chamber and the oil supply chamber. The sealing assembly may be disposed within the oil passage, with both ends of the sealing assembly extending outside the oil passage. The end of the sealing assembly located within the oil storage chamber may be configured to be sealedly connected to the inner wall of the oil passage, while the end of the sealing assembly located within the oil supply chamber may be configured to be at least partially unable to be inserted into the oil passage. The drive assembly may be configured to drive the end of the sealing assembly located within the oil storage chamber to be sealedly connected to the inner wall of the oil passage. The drive assembly may include a first drive member and a second drive member, which may repel or attract each other. The first drive member may be connected to the sealing assembly, and the second drive member may be connected to the housing or the partition.

[0037] In the atomizing device of the present application, the driving assembly can drive the blocking assembly to move so that one end of the blocking assembly located in the oil storage chamber is sealed and connected to the inner wall of the oil passage, thereby achieving the sealing of the oil supply chamber and the oil storage chamber. When the blocking assembly is subjected to other external forces (such as gravity or the user's throwing force) greater than the driving force of the driving assembly, the blocking assembly moves toward the oil storage chamber, and there is a gap between the blocking assembly and the oil passage. The smoke oil in the oil supply chamber can flow into the oil storage chamber through the gap. The blocking assembly is located at one end of the oil supply chamber and can prevent the blocking assembly from detaching from the oil passage; when the blocking assembly is subjected to other external forces less than the driving force of the driving assembly, the driving assembly can drive the blocking assembly to reset and re-seal the oil supply chamber and the oil storage chamber. Therefore, the opening and closing of the oil passage in the atomizing device of the present application is controllable, the gas is not likely to flow spontaneously between the oil supply chamber and the oil storage chamber, the air pressure in the oil storage chamber is balanced, and it is not easy to leak oil.

[0038] The following will mainly describe the specific structure of the atomization device.

[0039] See also Figures 1 to 5 The atomizing device 100 of the present application may include a housing 110. The housing 110 may form a cavity. The cross-section of the housing 110 may be circular, polygonal, elliptical, waist-shaped, or a special shape, without limitation. The housing 110 may be made of a transparent or opaque material. The housing 110 may be made of plastic or metal.

[0040] See also Figures 1 to 5, the atomizing device 100 of the present application may include a partition 120. The partition 120 may be arranged in the cavity, the partition 120 may be sealed and connected to the shell 110, the partition 120 may divide the cavity into an oil storage chamber 111 and an oil supply chamber 112, and the partition 120 may be provided with an oil passage 121 connecting the oil storage chamber 111 and the oil supply chamber 112. The partition 120 and the shell 110 may be integrally formed, or may be detachably connected, such as by bonding, screwing or snapping. The provision of the partition 120 enables the oil supply chamber 112 and the oil storage chamber 111 to be connected only through the oil passage 121, so that the connection and closure of the oil storage chamber 111 and the oil supply chamber 112 can be controlled by opening or closing the oil passage 121.

[0041] See also Figures 2 to 4 The separator 120 may include an abutment seat 122 and a connecting tube 123. The abutment seat 122 may be connected to one end of the connecting tube 123. The oil passage 121 may be formed by the abutment seat 122. The outer wall of the connecting tube 123 may be connected to the housing 110. The abutment seat 122 and the connecting tube 123 may be integrally formed (e.g., Figures 2 to 4 As shown), thus, the connection effect of the abutment seat 122 and the connecting tube 123 is better and oil leakage is not easy. The abutment seat 122 and the connecting tube 123 can also be detachably connected, such as by clamping, bonding or screw connection.

[0042] See also Figures 2 to 4 The connecting tube 123 can be connected to the wall of the oil supply chamber 112. Thus, the connecting tube 123 can guide the oil in the oil supply chamber 112 to flow to the oil passage 121, and the space of the oil supply chamber 112 is relatively large, which is also convenient for the connection of the connecting tube 123.

[0043] See also Figures 1 to 5 , the atomizing device 100 of the present application may include a sealing component 130. The sealing component 130 may be passed through the oil passage 121, and both ends of the sealing component 130 may extend out of the oil passage 121. One end of the sealing component 130 located in the oil storage chamber 111 may be configured to be able to be sealed and connected to the inner wall of the oil passage 121. Thus, the end of the sealing component 130 located in the oil storage chamber 111 can be driven to be sealed and connected to the inner wall of the oil passage 121. The end of the sealing component 130 located in the oil supply chamber 112 may be configured to be at least partially unable to be inserted into the oil passage 121, thereby, the sealing component 130 will not fall off from the oil passage 121.

[0044] See also Figures 1 to 5The sealing assembly 130 may include a guide member 131, a sealing member 132 and a limit member 133. The guide member 131 may be passed through the oil passage 121 and have both ends extending out of the oil passage 121. One end of the guide member 131 located in the oil storage chamber 111 may be connected to the sealing member 132, and the cross-sectional area of ​​the sealing member 132 may be larger than the cross-sectional area of ​​the inner wall of the oil passage 121. Thus, the sealing member 132 may be sealed and connected to one end of the oil passage 121 opposite thereto. One end of the guide member 131 located in the oil supply chamber 112 may be connected to the limit member 133, and the limit member 133 may be configured to be at least partially unable to be inserted into the oil passage 121. Thus, the limit member 133 may prevent the sealing assembly 130 from falling off the oil passage 121. The guide member 131 and the blocking member 132, as well as the guide member 131 and the limiting member 133, can be integrally formed or detachably connected (e.g., by bonding, screwing, or snapping). The spacing between the blocking member 132 and the limiting member 133 can be greater than the length of the oil passage 121, thereby allowing the oil to flow between the blocking assembly 130 and the oil passage 121.

[0045] See also Figure 3 and Figure 4 The cross-sectional area of ​​the limiting member 133 can be smaller than or equal to the cross-sectional area of ​​the inner wall of the oil passage 121. Thus, the limiting member 133 has less obstruction to the flow of the oil.

[0046] See also Figure 1 、 Figure 2 and Figure 5 The stopper 133 can be configured to seal against the inner wall of the oil passage 121. Specifically, the cross-sectional area of ​​the stopper 133 can be larger than the cross-sectional area of ​​the inner wall of the oil passage 121. Thus, the stopper 133 not only provides a position limit but also seals the oil passage 121, thereby improving the sealing effect between the oil storage chamber 111 and the oil supply chamber 112.

[0047] See also Figures 1 to 5 The atomizing device 100 of the present application may further include a driving assembly 140 . The driving assembly 140 may be used to drive one end of the blocking assembly 130 located in the oil storage chamber 111 to be sealedly connected to the inner wall of the oil passage 121 .

[0048] See also Figures 1 to 5 The drive assembly 140 may include a first drive member 141 and a second drive member 142 that repel or attract each other. The first drive member 141 may be connected to the blocking assembly 130, and the second drive member 142 may be connected to the housing 110 or the partition 120. Thus, the mutual repulsion or attraction between the first drive member 141 and the second drive member 142 can drive the blocking assembly 130 to move.

[0049] See also Figure 2 A driving component force is formed between the first driving member 141 and the second driving member 142, and the direction of the driving component force is parallel to the axis of the sealing assembly 130. When the first driving member 141 and the second driving member 142 are farthest apart, the driving component force can be greater than the gravity exerted on the sealing assembly 130 plus the gravity exerted on the first driving member 141. As a result, the driving assembly 140 can drive the sealing assembly 130 to overcome the movement of gravity, so that no matter what position the atomizing device 100 is in, the sealing assembly 130 can achieve the closure of the oil passage 121, thereby achieving a better sealing effect between the oil storage chamber 111 and the oil supply chamber 112. When the user needs to supply oil to the oil storage chamber 111, the sealing assembly 130 can be driven to open the oil passage 121 by swinging.

[0050] See also Figure 4 When the user adjusts the position of the atomizer device 100 so that the oil supply chamber 112 is at least partially located above the oil storage chamber 111, if the blocking component 130 is subjected to other external forces (such as gravity or the user's throwing force) that are greater than the driving force of the driving component 140, the blocking component 130 moves toward the oil storage chamber 111. The end of the blocking component 130 located in the oil supply chamber 112 can prevent the blocking component 130 from being separated from the oil passage 121, and the smoke liquid in the oil supply chamber 112 flows to the oil storage chamber 111 under gravity (such as Figure 4 (as indicated by the black arrow in the figure).

[0051] The first driving member 141 and the second driving member 142 may be magnets that repel each other. Thus, the blocking member 132 can be pushed to seal and connect with the inner wall of the oil passage 121 through the mutual repulsion of the first driving member 141 and the second driving member 142 .

[0052] In some embodiments, the first driving member 141 can be connected to one end of the blocking assembly 130 located in the oil storage chamber 111 (specifically, the blocking member 132), and the second driving member 142 can be connected to the cavity wall of the oil storage chamber 111. In the length direction of the oil passage 121, the distance between the second driving member 142 and the abutment seat 122 is greater than the maximum distance between the first driving member 141 and the abutment seat 122 (such as Figure 3 When the limiting member 133 is capable of sealing the oil passage 121 , the first driving member 141 can be connected to the blocking member 132 , and the second driving member 141 can be connected to the abutting seat 122 , the connecting cylinder 123 , or the wall of the oil supply chamber 112 .

[0053] In other embodiments, the first driving member 141 can be connected to one end of the blocking assembly 130 located in the oil supply chamber 112 (specifically, the limit member 133), and the second driving member 142 can be connected to the abutment seat 122 (such as Figure 4The first driving member 141 can be connected to the abutting seat 122 or the cavity wall of the oil supply cavity 112, and the second driving member 142 can be connected to the stopper 133 or the cavity wall of the oil storage cavity 111 when the stopper 133 can seal the oil passing channel 121.

[0054] The first driving member 141 and the second driving member 142 can attract each other. The first driving member 141 and the second driving member 142 can both be magnets. The first driving member 141 and the second driving member 142 can also be one magnet and the other made of ferromagnetic material, which can also realize the mutual attraction of the first driving member 141 and the second driving member 142.

[0055] The positions of the first driving member 141 and the second driving member 142 also have various arrangements when the first driving member 141 and the second driving member 142 attract each other.

[0056] In some embodiments, the first driving member 141 can be connected to one end of the sealing assembly 130 in the oil storage cavity 111 (specifically, the stopper 133), and the second driving member 142 can be connected to the abutting seat 122, the connecting barrel 123, or the cavity wall of the oil supply cavity 112. For example, please refer to Figure 2 The first driving member 141 can be connected to the stopper 133, and the second driving member 142 can be connected to the connecting barrel 123 when the stopper 133 can seal the oil passing channel 121. The first driving member 141 can be connected to the stopper 133, and the second driving member 141 can be connected to the cavity wall of the oil storage cavity 111 (as shown in Figure 5 ).

[0057] In other embodiments, the first driving member 141 can be connected to one end of the sealing assembly 130 in the oil supply cavity 112 (specifically, the stopper 133), and the second driving member 141 can be connected to the connecting barrel 123 or the cavity wall of the oil supply cavity 112. The distance between the second driving member 142 and the abutting seat 122 is greater than the maximum distance between the first driving member 141 and the abutting seat 122 in the length direction of the oil passing channel 121. The first driving member 141 can be connected to the stopper 133, and the second driving member 141 can be connected to the abutting seat 122 or the cavity wall of the oil storage cavity 111 when the stopper 133 can seal the oil passing channel 121.

[0058] The cross section of one end of the sealing assembly 130 in the oil supply cavity 112 (specifically, the stopper 133) can be D-shaped, crescent-shaped, oval-shaped, polygonal, waist-shaped, or irregularly shaped. In this way, the one end of the sealing assembly 130 in the oil supply cavity 112 can limit the rotation of the sealing assembly 130, so that the sealing assembly 130 is not easily pushed to rotate by the thrust generated by the tobacco tar vortex, thereby improving the effect of the sealing assembly 130 in closing the oil passing channel 121.

[0059] Similarly, the cross-section of the end of the sealing assembly 130 located within the oil storage chamber 111 (specifically, the stopper 133) may also be D-shaped, crescent-shaped, elliptical, polygonal, waist-shaped, or a special shape. Thus, the end of the sealing assembly 130 located within the oil supply chamber 112 can limit the rotation of the sealing assembly 130, thereby achieving a stable sealing connection between the sealing assembly 130 and the oil passage 121.

[0060] See also Figures 1 to 5 The atomizing device 100 of the present application may further include a sealing cylinder 150. One end of the sealing cylinder 150 may be inserted between the housing 110 and the partition 120. The sealing cylinder 150 may be used to seal the housing 110 and the partition 120. The other end of the sealing cylinder 150 may be used to seal and connect one end of the plugging assembly 130. The provision of the sealing cylinder 150 can strengthen the sealing connection between the housing 110 and the partition 120, and between the partition 120 and the plugging assembly 130, thereby improving the effect of the plugging assembly 130 in sealing the oil passage 121. The sealing cylinder 150 and the housing 110 may be bonded, snap-fitted, or screwed.

[0061] See also Figure 1 The present application also provides an electronic cigarette 200, which may include an electrical control device and the aforementioned atomizing device 100, wherein the atomizing device 100 and the electrical control device may be electrically connected. Thus, the electronic cigarette 200 of the present application has a relatively good sealing effect and is not prone to oil leakage.
