[0002] Large-capacity atomizers typically include a fuel tank that can store a large amount of e-liquid, ensuring a continuous supply. The atomizer draws the e-liquid from the tank and, powered by a power supply, atomizes it. The resulting mist flows through a nozzle connected to the atomizer chamber for inhalation.

[0003] However, the design of existing large-capacity atomizing equipment 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 the two, resulting in excessive air pressure in the oil storage tank, which in turn makes the atomizing equipment prone to oil leakage. Utility Model Content

[0034] This application discloses an atomization device, which may include a housing, a partition, a sealing assembly, a stopper, 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. The partition may extend through an oil passage connecting the oil storage chamber and the oil supply chamber. One end of the sealing assembly may be inserted into the oil passage, while the other end of the sealing assembly may be located within the oil storage chamber and have a cross-sectional area greater than the cross-sectional area of ​​the inner wall of the oil passage. The stopper may be located within the oil storage chamber and connected to the housing or the partition. The stopper may be disposed proximate to the sealing assembly and may be configured to limit movement of the sealing assembly. The drive assembly may be configured to drive the sealing assembly so that the end of the sealing assembly located within the oil storage chamber is 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 inner wall of the housing, the partition, or the stopper.

[0035] In the atomization device, the driving assembly can drive the blocking assembly to move to seal the inner wall of the oil passing channel, so that the oil supply cavity and the oil storage cavity are sealed. When the blocking assembly is subjected to other external forces (such as gravity or the user's swinging force) greater than the driving assembly, the blocking assembly moves towards the oil storage cavity, and the blocking assembly has a gap with the oil passing channel, so that the tobacco tar in the oil supply cavity can flow into the oil storage cavity through the gap, and the limiting piece can limit the blocking assembly to avoid the blocking assembly from falling off the oil passing channel; when the blocking assembly is subjected to other external forces less than the force of the driving assembly, the driving assembly can drive the blocking assembly to reseal the inner wall of the oil passing channel. Thus, the opening and closing of the oil passing channel in the atomization device of the present application is controllable, and the gas is not easy to spontaneously flow between the oil supply cavity and the oil storage cavity, and the gas pressure in the oil storage cavity is balanced, and the oil is not easy to leak.

[0036] The specific structure of the atomization device will be mainly described below.

[0037] Please refer to Figures 1 to 4 The atomization device 100 of the present application can include a housing 110. The housing 110 can form a cavity. The cross section of the housing 110 can be circular, polygonal, oval, waist-shaped or irregular, etc., without limitation. The housing 110 can be made of transparent or opaque material. The housing 110 can be made of plastic or metal material.

[0038] Please refer to Figures 1 to 4 The atomization device 100 of the present application can include a partition 120. The partition 120 can be arranged in the cavity, the partition 120 can be sealingly connected to the housing 110, the partition 120 can divide the cavity into an oil storage cavity 111 and an oil supply cavity 112, and the partition 120 can be provided with an oil passing channel 121 communicating the oil storage cavity 111 and the oil supply cavity 112. The partition 120 and the housing 110 can be integrally formed, or can be detachably connected, such as bonding, screwing or clamping. The provision of the partition 120 makes the oil supply cavity 112 and the oil storage cavity 111 only able to communicate through the oil passing channel 121, so that by opening or closing the oil passing channel 121, the communication and closure of the oil storage cavity 111 and the oil supply cavity 112 can be controlled.

[0039] Please refer to Figures 2 to 4 The partition 120 can include an abutment seat 122 and a connecting barrel 123, the abutment seat 122 can be connected to one end of the connecting barrel 123, the oil passing channel 121 can be formed by penetrating the abutment seat 122, and the outer wall of the connecting barrel 123 can be connected to the housing 110. The abutment seat 122 and the connecting barrel 123 can be integrally formed (as shown in Figures 2 to 4 ), so that the connection effect of the abutment seat 122 and the connecting barrel 123 is good, and the oil is not easy to leak. The abutment seat 122 and the connecting barrel 123 can also be detachably connected, such as clamping, bonding or screwing.

[0040] 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.

[0041] See also Figures 1 to 4 The atomizing device 100 of the present application may include a blocking assembly 130. The blocking assembly 130 may be disposed at the oil passage 121. One end of the blocking assembly 130 may be inserted into the oil passage 121, and the other end of the blocking assembly 130 may be located within the oil storage chamber 111 and have a cross-sectional area greater than the cross-sectional area of ​​the inner wall of the oil passage 121. Thus, the end of the blocking assembly 130 located within the oil storage chamber 111 can be sealed against the inner wall of the oil passage 121.

[0042] See also Figures 1 to 4 The sealing assembly 130 may include a guide member 131 and a sealing member 132. The guide member 131 may be disposed within the oil passage 121. The end of the guide member 131, which is adjacent to the oil reservoir 111, may extend beyond the oil passage 121 and connect to the sealing member 132. The cross-sectional area of ​​the sealing member 132 may be greater than the cross-sectional area of ​​the inner wall of the oil passage 121. Thus, the sealing member 132 may be sealed against the inner wall of the oil passage 121.

[0043] See also Figures 1 to 4 The atomizing device 100 of the present application may include a limiter 150. The limiter 150 may be located in the oil storage chamber 111, may be connected to the housing 110 or the partition 120, may be disposed near the blocking assembly 130, and may be used to limit the movement of the blocking assembly 130.

[0044] One end of the limiting member 150 can be connected to the housing 110 (specifically, the wall of the oil storage chamber 111) or the partition 120, and the other end of the limiting member 150 can be a free end. The limiting member 150 can be roughly L-shaped (such as Figure 3 shown).

[0045] One end of the limiting member 150 can be connected to the housing 110 or the partition 120, and the other end of the limiting member 150 can also be connected to the housing 110 or the partition 120. The limiting member 150 can be roughly I-shaped (eg Figure 1 As shown), U-shaped or [shaped (as Figure 4 shown).

[0046] The limiting member 150 and the shell 110 (or the partition 120) can be integrally formed. In this way, the connection between the limiting member 150 and the shell 110 (or the partition 120) is relatively tight. The limiting member 150 and the shell 110 (or the partition 120) can also be detachably connected, for example, can be bonded, clamped or screwed. In this way, the limiting member 150 and the shell 110 (or the partition 120) are relatively easy to manufacture and connect.

[0047] When the blocking assembly 130 is in sealing connection with the inner wall of the oil passing channel 121, the distance between the limiting member 150 and the end of the blocking assembly 130 located in the oil storage cavity 111 can be greater than or equal to 0.3 mm and less than or equal to 3 mm. In this way, when the blocking assembly 130 abuts against the limiting member 150, the gap between the blocking assembly 130 and the oil passing channel 121 is relatively appropriate in size, and the tobacco tar can flow relatively smoothly from the oil supply cavity 112 to the oil storage cavity 111. Further, when the blocking assembly 130 is in sealing connection with the inner wall of the oil passing channel 121, the distance between the limiting member 150 and the blocking assembly 130 can be 0.3-1 mm, 0.3-0.8 mm, 1-2 mm, 0.3-2 mm, 0.7-1.9 mm, 0.5-2.6 mm, 0.4-2 mm, 0.3-2.7 mm or 1-3 mm, etc. Still further, the above distance can be 0.3 mm, 0.4 mm, 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1 mm, 1.3 mm, 1.5 mm, 1.7 mm, 1.9 mm, 2 mm, 2.1 mm, 2.3 mm, 2.5 mm, 2.6 mm, 2.7 mm, 2.8 mm, 2.9 mm or 3 mm.

[0048] The thickness of the limiting member 150 can be greater than or equal to 0.1 mm and less than or equal to 2 mm. In this way, the limiting member 150 is relatively strong, and even if the user throws the blocking assembly 130 towards the limiting member 150 with force, the limiting member 150 is not easily damaged by the blocking assembly 130, and at the same time, the limiting member 150 does not occupy too much space. The thickness of the limiting member 150 can be 0.1-1 mm, 0.3-1.8 mm, 0.1-0.4 mm, 0.2-1.5 mm, 0.7-1.9 mm, 0.5-1.6 mm, 0.4-1.5 mm, 0.3-1.7 mm or 1-1.3 mm, etc. Still further, the thickness of the limiting member 150 can be 0.1 mm, 0.2 mm, 0.3 mm, 0.4 mm, 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1 mm, 1.1 mm, 1.2 mm, 1.3 mm, 1.4 mm, 1.5 mm, 1.6 mm, 1.7 mm, 1.8 mm, 1.9 mm or 2 mm.

[0049] Please refer to Figures 1 to 4The atomizing device 100 of the present application may further include a drive assembly 140. The drive assembly 140 may be used to drive the blocking assembly 130 to move so that one end of the blocking assembly 130 located in the oil storage chamber 111 (specifically, the blocking member 132) is sealedly connected to the inner wall of the oil passage 121.

[0050] See also Figures 1 to 4 The driving component 140 may include a first driving member 141 and a second driving member 142. The first driving member 141 and the second driving member 142 repel or attract each other. The first driving member 141 can be connected to the sealing component 130, and the second driving member 142 can be connected to the inner wall of the shell 110, the partition 120 or the limit member 150. Therefore, the mutual attraction or mutual repulsion between the first driving member 141 and the second driving member 142 can push the sealing component 130 toward the oil channel 121 and be sealed with the inner wall of the oil channel 121.

[0051] 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 gravity and move, so that the atomizing device 100 can achieve the closure of the oil passage 121 regardless of its position state, and there is a relatively good 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.

[0052] 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 component 140, the blocking component 130 moves toward the oil storage chamber 111, and a gap is formed between the blocking component 130 and the oil passage 121. The smoke oil in the oil supply chamber 112 can flow into the oil storage chamber 111 through the gap (such as Figure 4 As shown by the black arrow in FIG), the limiting member 150 can prevent the blocking component 130 from detaching from the oil passage 121.

[0053] The first driving member 141 and the second driving member 142 can be magnets that repel each other. The first driving member 141 can be connected to one end of the blocking component 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 As shown in FIG. 1 , the mutual repulsion between the first driving member 141 and the second driving member 142 can drive the blocking member 132 to move so as to seal the oil passage 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 have one of them be a magnet and the other be made of ferromagnetic material, which can achieve the mutual attraction between the first driving member 141 and the second driving member 142. The first driving member 141 can be connected to one end of the blocking component 130 located in the oil storage chamber 111 (specifically, the blocking component 132), and the second driving member 142 can be connected to the abutment seat 122 (such as Figure 4 As shown), connecting tube 123 (as Figure 2 As shown) or the wall of the oil supply chamber 112.

[0055] See also Figures 1 to 4 The atomizing device 100 of the present application may further include a sealing cylinder 160. One end of the sealing cylinder 160 may be inserted between the housing 110 and the partition 120. The sealing cylinder 160 may be used to seal the housing 110 and the partition 120. The other end of the sealing cylinder 160 may be used to seal and connect one end of the plugging assembly 130. The provision of the sealing cylinder 160 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 160 and the housing 110 may be bonded, snap-fitted, or screwed.

[0056] 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.
