Description

Technical Field

[0001] This application relates to the field of atomization technology, and in particular to an electronic cigarette. Background Technology

[0002] High-capacity atomizing devices typically include a refill tank, which can store a large amount of e-liquid, thus continuously supplying it to the storage tank. The atomizing component absorbs the e-liquid from the storage tank and, powered by a power supply, atomizes it. The atomized vapor flows out through the mouthpiece connected to the atomizing chamber for the user to inhale.

[0003] However, the design of existing large-capacity atomizing devices is not reasonable enough. The sealing effect between the oil supply tank and the oil storage tank is not good, and the gas in the oil supply tank and the oil storage tank can easily flow between them, resulting in excessively high gas pressure in the oil storage tank, which in turn makes the atomizing device prone to oil leakage. Utility Model Content

[0004] The main purpose of this application is to provide an electronic cigarette that solves the technical problem of oil leakage caused by poor sealing in large-capacity atomizing devices.

[0005] To achieve the above objectives, this application proposes an electronic cigarette, which includes:

[0006] The shell has interconnected oil storage chambers and oil supply chambers inside;

[0007] A separator is disposed between the oil storage chamber and the oil supply chamber. The separator is sealed to the housing. The separator has an oil passage that connects the oil storage chamber and the oil supply chamber.

[0008] A sealing assembly is disposed at the oil passage; and

[0009] A drive assembly is used to drive the sealing assembly to close the oil passage. The drive assembly includes an inner magnet and an outer magnet that repel each other. The inner magnet is connected to the sealing assembly. The outer wall of the housing is provided with a connecting groove. The connecting groove is located away from the separator. The outer magnet has two connection states with the connecting groove: connected and disconnected.

[0010] Optionally, the distance between the connecting groove and the separator is greater than or equal to 10 mm and less than or equal to 40 mm.

[0011] Optionally, the distance between the connecting groove and the separator is greater than or equal to 15mm and less than or equal to 30mm.

[0012] Optionally, the mutual repulsive force between the inner magnet and the outer magnet when they are furthest apart is greater than the sum of the gravity of the sealing assembly and the gravity of the inner magnet.

[0013] Optionally, the sealing assembly is inserted into the oil passage.

[0014] Optionally, the sealing assembly includes a guide and a sealing member sleeved on the guide. The end of the guide away from the sealing member is inserted into the oil passage. The sealing member is connected to the inner magnet. The cross-sectional area of ​​the guide is smaller than the cross-sectional area of ​​the inner wall of the oil passage, and the cross-sectional area of ​​the sealing member is larger than the cross-sectional area of ​​the inner wall of the oil passage.

[0015] Optionally, the sealing assembly further includes a limiting member connected to the end of the sealing assembly away from the guide member.

[0016] Optionally, the end of the guide member away from the sealing member extends out of the oil passage, and the sealing assembly further includes a limiting member connected to the end of the guide member away from the sealing member, wherein the limiting member is at least partially unable to be inserted into the oil passage.

[0017] Optionally, the electronic cigarette further includes:

[0018] The electrical control device has two connection states with the atomizing device: connected and disconnected. The electrical control device includes a mounting base. The side of the mounting base facing the atomizing device has a mounting groove corresponding to the connection groove. The external magnet is installed in the mounting groove.

[0019] Optionally, the electronic cigarette further includes:

[0020] A first adsorption element and a second adsorption element that can attract each other, wherein the first adsorption element is disposed on the side of the housing where the connecting groove is provided, and the second adsorption element is disposed on the side of the mounting base where the mounting groove is provided, corresponding to the first adsorption element.

[0021] In this electronic cigarette application, the e-liquid and vapor in the supply chamber can only flow into the storage chamber through the oil passage. When the outer magnet is connected to the connecting groove, the inner magnet is repelled by the outer magnet, which moves the sealing component to the oil passage and seals it, thus sealing the storage chamber and the supply chamber. When the outer magnet is separated from the connecting groove, the inner magnet is no longer repelled by the outer magnet, and the sealing component and the inner magnet can move under gravity, allowing the sealing component to open the oil passage. By connecting or separating the outer magnet from the connecting groove, the sealing and connection between the storage chamber and the supply chamber can be controlled, preventing the connection between the supply chamber and the storage chamber from opening automatically, making it difficult for gas to flow between them, maintaining pressure balance in the storage chamber, and reducing the likelihood of oil leakage in the atomizing device.

[0033] This application discloses an electronic cigarette, which may include an atomizing device. The atomizing device may include a housing, a separator, a sealing assembly, and a driving assembly. The housing may have an internally connected oil storage chamber and an oil supply chamber. The separator may be located between the oil storage chamber and the oil supply chamber, and the separator may be sealed to the housing. The separator may have an oil passage connecting the oil storage chamber and the oil supply chamber. The sealing assembly may be located at the oil passage. The driving assembly can be used to drive the sealing assembly to close the oil passage. The driving assembly may include a mutually repelling inner magnet and an outer magnet. The inner magnet can connect to the sealing assembly. The outer wall of the housing may have a connecting groove, which may be located away from the separator. The outer magnet and the connecting groove can have both connected and disconnected connection states.

[0034] In this electronic cigarette application, the e-liquid and vapor in the supply chamber can only flow into the storage chamber through the oil passage. When the outer magnet is connected to the connecting groove, the inner magnet is repelled by the outer magnet, which moves the sealing component to the oil passage and seals it, thus sealing the storage chamber and the supply chamber. When the outer magnet is separated from the connecting groove, the inner magnet is no longer repelled by the outer magnet, and the sealing component and the inner magnet can move under gravity, allowing the sealing component to open the oil passage. By connecting or separating the outer magnet from the connecting groove, the sealing and connection between the storage chamber and the supply chamber can be controlled, preventing the connection between the supply chamber and the storage chamber from opening automatically, making it difficult for gas to flow between them, maintaining pressure balance in the storage chamber, and reducing the likelihood of oil leakage in the atomizing device.

[0035] The following will mainly describe the specific structure of electronic cigarettes.

[0036] Please see Figures 1 to 4The atomizing device 100 may include a housing 110. The housing 110 may have an interconnected oil storage chamber 111 and an oil supply chamber 112. The atomizing device 100 may include an atomizing component (not shown), which may be disposed within the oil storage chamber 111. The atomizing component can absorb the e-liquid within the oil storage chamber 111 and atomize it. The housing 110 may have an oil supply chamber 112, which can store a large amount of e-liquid, thereby continuously supplying oil to the oil storage chamber 111.

[0037] Please see Figures 1 to 4 The atomizing device 100 may include a separator 120. The separator 120 may be disposed between the oil storage chamber 111 and the oil supply chamber 112. The separator 120 may be sealed to the housing 110, and may have an oil passage 121 extending through it, connecting the oil storage chamber 111 and the oil supply chamber 112. The separator 120 and the housing 110 may be integrally formed or detachably connected, such as by bonding, screwing, or snap-fitting. The separator 120 ensures that the oil supply chamber 112 and the oil storage chamber 111 can only be connected through the oil passage 121, thereby controlling the connection and disconnection between the oil storage chamber 111 and the oil supply chamber 112 by opening or closing the oil passage 121.

[0038] Please see Figures 1 to 4 The atomizing device 100 may include a blocking component 130. The blocking component 130 may be disposed at the oil passage 121, and at least a portion of the cross-sectional area of ​​the blocking component 130 may be larger than the cross-sectional area of ​​the inner wall of the oil passage 121, thereby the blocking component 130 may be used to open or close the oil passage 121.

[0039] Please see Figures 1 to 4 The atomizing device 100 may further include a drive assembly 140. The drive assembly 140 can be used to drive the sealing assembly 130 to close the oil passage 121. Specifically, the drive assembly 140 may include an inner magnet 141 and an outer magnet 142 that can be magnetically connected. The inner magnet 141 can be connected to the sealing assembly 130. The outer wall of the housing 110 may be provided with a connecting groove 113, which may be located away from the separator 120. The outer magnet 142 and the connecting groove 113 may have two connection states: connected and disconnected. The outer magnet 142 and the connecting groove 113 may abut, snap, screw, or adhere. The outer magnet 142 can be removed from the connecting groove 113 by the user, or it can be installed in the connecting groove 113 by the user.

[0040] In the electronic cigarette 10 of this application, the e-liquid and vapor in the supply chamber 112 can only flow into the storage chamber 111 through the oil passage 121. Please refer to... Figure 2When the outer magnet 142 is connected to the connecting groove 113, the inner magnet 141, repelled by the outer magnet 142, can move the sealing assembly 130 to the oil passage 121 and close the oil passage 121, thus sealing the oil storage chamber 111 and the oil supply chamber 112. (See also...) Figure 3 When the outer magnet 142 separates from the connecting groove 113, the inner magnet 141 is no longer repelled by the outer magnet 142. The sealing assembly 130 and the inner magnet 141 can move under gravity, allowing the sealing assembly 130 to open the oil passage 121, and the e-liquid in the oil supply chamber 112 to flow into the oil storage chamber 111 (e.g., ...). Figure 3 (As indicated by the black arrow in the image). By connecting or separating the external magnet 142 from the connecting groove 113, the sealing and connection between the oil storage chamber 111 and the oil supply chamber 112 can be controlled. As a result, the connection between the oil supply chamber 112 and the oil storage chamber 111 will not open automatically, gas will not easily flow between the two, the air pressure in the oil storage chamber 111 will be balanced, and the atomizing device 100 will not easily leak oil.

[0041] The mutual repulsive force between the inner magnet 141 and the outer magnet 142 can be greater than the sum of the gravity acting on the sealing assembly 130 and the gravity acting on the inner magnet 141. This mutual repulsive force can be the repulsive force when the inner adsorption component 141 and the outer adsorption component 142 are at their furthest point. Therefore, the driving assembly 140 can drive the sealing assembly 130 to move against gravity, and the atomizing device 100 can achieve a relatively good sealing effect in both the oil supply chamber 112 and the oil storage chamber 111, regardless of its position.

[0042] The distance between the connecting groove 113 and the separator 120 can be greater than or equal to 10 mm and less than or equal to 40 mm. Therefore, the distance between the connecting groove 113 and the separator 120 is suitable. When the outer magnet 142 is connected to the connecting groove 113, the inner magnet 141, repelled by the outer magnet 142, can move the sealing assembly 130 to the oil passage 121 and close the oil passage 121. Further, the distance between the connecting groove 113 and the separator 120 can be 15–30 mm, 25–40 mm, 10–30 mm, 18–20 mm, 15–20 mm, 10–15 mm, 12–18 mm, or 15–20 mm, etc. Even further, the distance between the connecting groove 113 and the separator 120 can be 10 mm, 12 mm, 15 mm, 18 mm, 20 mm, 22 mm, 25 mm, 28 mm, 30 mm, 35 mm, or 40 mm, etc.

[0043] Please see Figures 1 to 4 The sealing component 130 can be inserted into the oil passage 121. Therefore, the inner wall of the oil passage 121 can limit the movement direction of the sealing component 130, thereby facilitating the control of the movement of the sealing component 130.

[0044] Please see Figures 1 to 4 The sealing assembly 130 may include a guide 131 and a sealing member 132 sleeved on the guide 131. The end of the guide 131 away from the sealing member 132 can be inserted into the oil passage 121. The sealing member 132 can be connected to an inner magnet 141. The cross-sectional area of ​​the guide 131 can be smaller than the cross-sectional area of ​​the inner wall of the oil passage 121, and the cross-sectional area of ​​the sealing member 132 can be larger than the cross-sectional area of ​​the inner wall of the oil passage 121. Therefore, the sealing assembly 130 can move along the extending direction of the guide 131, and the sealing member 132 cannot be inserted into the oil passage 121, thus sealing the oil passage 121. The cross-sectional area of ​​the guide 131 is smaller than the cross-sectional area of ​​the inner wall of the oil passage 121, allowing the e-liquid in the oil chamber 112 to flow through the gap between the sealing assembly 130 and the oil passage 121 to the oil storage chamber 111.

[0045] Please see Figures 1 to 4 The sealing component 132 may include a sealing block 134 and a connecting arm 135 connected to each other. The sealing block 134 can be connected to the guide component 131, and the connecting arm 135 can be connected to the inner magnet 141. Therefore, the connection effect between the sealing component 132 and the guide component 131, and between the sealing component 132 and the inner magnet 141, is relatively good, resulting in a better effect of the driving assembly 140 moving the sealing assembly 130. The sealing block 134 and the connecting arm 135 can be integrally formed (e.g., Figures 1 to 4 (As shown), it can also be detachably connected, such as by gluing, snap-fitting or screwing.

[0046] Please see Figure 4 The sealing assembly 130 may further include a limiting member 133, which can be connected to the end of the sealing member 132 away from the guide member 131. Thus, the guide member 131 can limit the inner magnet 141, so that the inner magnet 141 can always be located between the connecting groove 113 and the separator 120, so that when the outer magnet 142 is connected to the connecting groove 113, the inner magnet 141 can move towards the oil passage 121 due to the repulsive force of the outer magnet 142.

[0047] Please see again Figure 4 When the electronic cigarette 10 is inverted, the end of the limiting member 133 away from the sealing member 132 can abut against the wall of the oil storage chamber 111, allowing the e-liquid in the supply chamber 112 to flow into the oil storage chamber 111 under the action of gravity (e.g., Figure 4 (As indicated by the black arrow in the image).

[0048] Please see Figures 1 to 3In another embodiment, the end of the guide 131 away from the sealing member 132 can extend out of the oil passage 121, and the limiting member 133 can be connected to the end of the guide 131 away from the sealing member 132. The limiting member 133 cannot at least partially penetrate into the oil passage 121. Thus, the limiting member 133 can limit the inner magnet 141, so that the inner magnet 141 can always be located between the connecting groove 113 and the separator 120 (e.g., Figures 1 to 3 As shown in the diagram, when the outer magnet 142 is connected to the connecting groove 113, the inner magnet 141 can move toward the oil passage 121 due to the mutual repulsion between it and the outer magnet 142. The cross-sectional area of ​​the limiting member 133 can be greater than, equal to or less than the cross-sectional area of ​​the inner wall of the oil passage 121, as long as it cannot be completely inserted into the oil passage 121, and there is no limitation.

[0049] Please see Figure 3 When the electronic cigarette 10 is tilted, the e-liquid in the supply chamber 112 flows into the storage chamber 111 under the action of gravity (e.g., ...). Figure 3 (As indicated by the black arrow in the image).

[0050] Please see Figure 1 The electronic cigarette 10 may also include an electronic control device 200. The electronic control device 200 may be connected to the atomizing device 100 (e.g., ...). Figure 1 (as shown) and separation (as shown) Figure 2 and Figure 3 As shown, there are two connection states. When the electronic control device 200 is connected to the atomizing device 100, the electronic control device 200 and the atomizing device 100 can achieve electrical conduction, so that the atomizing device 100 can atomize the e-liquid.

[0051] Please see Figure 1 The electronic control device 200 may include a mounting base 210. The side of the mounting base 210 facing the atomizing device 100 may be provided with a mounting groove 211 corresponding to the connecting groove 113, and the outer magnet 142 may be installed in the mounting groove 211. Thus, when the electronic control device 200 is connected to the atomizing device 100, the repulsive force between the outer magnet 142 and the inner magnet 141 drives the inner magnet 141 to move toward the separator 120. The inner magnet 141 drives the sealing assembly 130 to move toward the separator 120 and close the oil passage 121. When the electronic control device 200 is separated from the atomizing device 100, the repulsive force between the outer magnet 142 and the inner magnet 141 disappears, and the sealing assembly 130 can move under the action of gravity to open the oil passage 121. The e-liquid in the oil supply chamber 112 flows to the oil storage chamber 111 under the action of gravity. With the above settings, when the electric control device 200 is connected to the atomizing device 100, the oil storage chamber 111 and the oil supply chamber 112 of the atomizing device 100 can be automatically closed; when the electric control device 200 is separated from the atomizing device 100, the oil supply chamber 112 can inject oil into the oil storage chamber 111.

[0052] Please see Figure 1 The electronic cigarette 10 may further include a first adsorption element 150 and a second adsorption element 220 capable of adsorbing and connecting. The first adsorption element 150 may be disposed on the side of the housing 110 where the connection groove 113 is provided, and the second adsorption element 220 may be disposed on the side of the mounting base 210 where the mounting groove 211 is provided, corresponding to the first adsorption element 150. Through the adsorption of the first adsorption element 150 and the second adsorption element 220, the connection effect between the electronic control device 200 and the atomizing device 100 can be enhanced.
