Oil bottle

Abstract

The utility model discloses an oil bottle. According to the oil bottle, the first bottle body and the second bottle body are detachably connected, so that the oil bottle can supplement tobacco tar by separating the first bottle body from the second bottle body, and therefore the oil bottle can be repeatedly used, and the utilization rate of the tobacco tar is increased. Compared with tobacco tar waste caused by tobacco tar residue on the inner wall of the tobacco tar bin when a disposable tobacco tar bottle is discarded, the reusable tobacco tar bottle can remarkably reduce waste caused by tobacco tar residue, the utilization rate of the tobacco tar is increased, the tobacco tar bottle can be inversely installed on the atomizer body by further arranging a leakage-proof piece at the bottle neck, and the tobacco tar can be reused. The leakage of the tobacco tar can be reduced or even avoided after the first bottle body and the second bottle body are detached from the atomizer main body, and the oil leakage prevention performance of the oil bottle is further improved by arranging the sealing piece to seal the joint of the first bottle body and the second bottle body.

Description

Technical Field

[0001] The present application relates to the technical field of atomizers, and in particular to an oil bottle. Background Art

[0002] An atomizer is a device that can heat the target liquid (e-liquid) to form an aerosol for the user to inhale. Compared with traditional cigarettes, atomizers are easy to carry and use, and can greatly reduce the impact of harmful substances on users and people around them.

[0003] Atomizers include disposable atomizers and reusable atomizers. For reusable atomizers, the core is the replenishment of the e-liquid. In existing reusable atomizers, for the oil bottle installed upside down in the atomizer body (i.e., the bottle mouth of the oil bottle faces the opposite direction to the atomizer mouthpiece), due to the structure and installation and use status of the oil bottle, the replenishment of the e-liquid is usually to directly replace another oil bottle containing e-liquid and discard the replaced oil bottle. However, for users, if the oil bottle is not reused, it will not only increase their consumption costs, but also reduce the utilization rate of the e-liquid. Utility Model Content

[0004] The main purpose of the present application is to provide an oil bottle to solve the problem of low utilization rate of oil bottles used upside down in the prior art.

[0005] The present application provides an oil bottle, comprising:

[0006] First bottle body;

[0007] a second bottle body, the second bottle body being detachably connected to the first bottle body to form an oil tank and an oil outlet, the oil tank being in communication with the oil outlet;

[0008] A sealing member, which can be sealed at the connection between the first bottle body and the second bottle body;

[0009] A leak-proof component is arranged in the oil outlet hole to prevent the oil in the oil bin from leaking.

[0010] Furthermore, the leakage-proof component is made of elastic material so that the leakage-proof component has elastic recovery capability.

[0011] Furthermore, the leakage-proof part comprises an integrally formed first sealing part and a second sealing part, the first sealing part is a tubular structure and is sealed and connected to the oil outlet hole through a fixing ring, and the second sealing part is sealed and connected to the first sealing part in a radial direction;

[0012] When the oil guide tube presses against the second sealing part and tears the second sealing part, the torn second sealing part returns to the center and elastically seals to the outer wall of the oil guide tube. When the oil guide tube exits the second sealing part, the second sealing part closes toward the center.

[0013] Furthermore, the second bottle body structure is formed with a bottleneck, the bottleneck structure is formed with a bottle mouth, and the leak-proof component is installed on the inner side of the bottleneck along the direction from the oil tank toward the bottle mouth.

[0014] Further, the oil outlet hole comprises a first hole and a second hole, the first hole is close to the bottle mouth, the second hole is close to the oil tank, and the cross-sectional area of ​​the first hole is smaller than the cross-sectional area of ​​the second hole so that a limited step surface is formed at the connection between the first hole and the second hole;

[0015] The fixing ring seals the leak-proof component to the limiting step surface in the axial direction, and / or seals the leak-proof component to the inner side wall of the second hole in the radial direction.

[0016] Furthermore, the leakage-proof component has a first end face and a second end face relative to each other in the axial direction, and the fixing ring includes a ring end face and a ring side face that are connected to each other. When the leakage-proof component is installed in the second hole, the first end face abuts against the limiting step face, the ring end face abuts against the second end face, and the ring side face presses and seals the leakage-proof component against the inner wall of the second hole in the radial direction.

[0017] Furthermore, an annular guide slope is formed on one end of the bottleneck close to the bottle mouth.

[0018] Furthermore, the first bottle body is plugged and engaged with the second plugging portion of the second bottle body through the first plugging portion, wherein the first plugging portion is provided with a plurality of clamping positions, and the second plugging portion is provided with a matching clamping portion corresponding to each of the clamping positions.

[0019] Furthermore, a sealing groove is formed on an outer side wall of the second plug-in portion, and the sealing member is disposed in the sealing groove. When the second plug-in portion is inserted into the first plug-in portion, the sealing member seals between the first plug-in portion and the second plug-in portion.

[0020] Furthermore, the second bottle body includes a first abutting portion extending radially outward, and when the second bottle body is inserted into the first bottle body, the open end of the first bottle body abuts against the first abutting portion.

[0021] In the oil bottle of the present application, the first bottle body and the second bottle body are detachably connected, so that the oil bottle can be refilled with oil by separating the first bottle body and the second bottle body, thereby realizing the reuse of the oil bottle and improving the utilization rate of the oil. Compared with the waste of oil caused by residual oil on the inner wall of the oil tank when the disposable oil bottle is discarded, the reusable oil bottle in the present application can also significantly reduce the waste of oil caused by residual oil, thereby improving the utilization rate of oil, and further by providing a leak-proof part at the bottleneck, the oil bottle can be installed upside down on the atomizer body, or after being disassembled from the atomizer body, the leakage of oil can be reduced or even avoided, and the connection between the first bottle body and the second bottle body can be sealed by providing a sealing part to further improve the oil bottle's anti-leakage performance.

[0038] See also Figure 1-8 As shown, the present application provides an oil bottle 10, which is installed upside down in the atomizer body for storing and supplying the tobacco oil required for atomization.

[0039] Furthermore, the oil bottle 10 includes a first bottle body 11, a second bottle body 12, a sealing member 14 and a leak-proof member 15. The second bottle body 12 is detachably connected to the first bottle body 11 to form an oil bin 13 and an oil outlet 122, and the oil bin 13 is connected to the oil outlet 122. The sealing member 14 can be sealed at the connection between the first bottle body 11 and the second bottle body 12. The leak-proof member 15 is arranged in the oil outlet 122 to prevent the oil in the oil bin 13 from leaking.

[0040] By detachably connecting the first bottle body 11 and the second bottle body 12, the oil bottle 10 can be refilled with oil by separating the first bottle body 11 and the second bottle body 12, thereby realizing the reuse of the oil bottle 10 and improving the utilization rate of the oil. Compared with the waste of oil caused by the oil residue on the inner wall of the oil tank 13 when the disposable oil bottle 10 is discarded, the reusable oil bottle 10 in the present application can also significantly reduce the waste of oil caused by the residue, thereby improving the utilization rate of the oil.

[0041] Furthermore, by providing a leak-proof member 15 at the bottleneck 121, the oil bottle 10 can be installed upside down on the atomizer body, or the leakage of the smoke oil can be reduced or even avoided after being removed from the atomizer body. In addition, by providing a sealing member 14 to seal the connection between the first bottle body 11 and the second bottle body 12, the anti-leakage performance of the oil bottle 10 can be further improved.

[0042] Furthermore, the atomizer body also includes an oil guide tube 21, and the leak-proof member 15 is made of an elastic material so that the leak-proof member 15 has elastic recovery ability, so that after the oil bottle 10 is inverted and installed on the atomizer body, the leak-proof member 15 pressed and torn by the oil guide tube 21 can rely on the elastic recovery ability to return to the outer wall of the corresponding oil guide tube 21 and be sealed on the outer wall of the oil guide tube 21, so that the tobacco oil in the oil bottle 10 can only flow outward from the inside of the oil guide tube 21, but cannot flow outward from between the leak-proof member 15 and the outer wall of the corresponding oil guide tube 21.

[0043] In one embodiment, the leakage prevention part 15 includes an integrally formed first sealing portion 153 and a second sealing portion 154, wherein the first sealing portion 153 is a tubular structure and is sealed and connected to the oil outlet hole 122 via a fixing ring 16, and the second sealing portion 154 is sealed and connected to the first sealing portion 153 in the radial direction and separates the first sealing portion 153 of the tubular structure.

[0044] When the oil guiding pipe 21 presses against the second sealing portion 154 and tears the second sealing portion 154, the torn second sealing portion 154 returns to the center and elastically seals to the outer wall of the oil guiding pipe 21, that is, the elastic recovery ability of the second sealing portion 154 is used to achieve a sealed connection between the torn second sealing portion 154 and the corresponding outer side wall of the oil guiding pipe 21.

[0045] Since the second sealing portion 154 torn by the oil guide tube 21 will form a corresponding crack, and the second sealing portion 154 has elastic recovery ability, when the oil guide tube 21 exits the second sealing portion 154, the second sealing portion 154 tends to close toward the center, that is, when the oil bottle 10 is removed from the atomizer body, even if the oil bottle 10 is inverted, the remaining oil in the oil bottle 10 is difficult to leak from the nearly closed crack.

[0046] Furthermore, the second bottle body 12 is a hollow structure with two open ends. One end of the second bottle body 12 is connected to the first bottle body 11 to form the oil tank 13.

[0047] Furthermore, the second bottle body 12 is structured to form a bottleneck 121. The bottleneck 121 is structured to form the oil outlet 122 connected to the oil tank 13. When the bottle body is invertedly installed on the atomizer body, the smoke oil in the oil tank 13 can flow out through the oil outlet 122.

[0048] Further, the bottleneck 121 is structured to form a bottle mouth, which is an opening of the oil outlet 122 at one end away from the oil tank 13. The leak-proof member 15 is installed on the inner side of the bottleneck 121 along the direction from the oil tank 13 toward the bottle mouth. That is, the leak-proof member 15 is installed inside the bottleneck 121.

[0049] Furthermore, the oil outlet hole 122 includes a first hole 1221 and a second hole 1222 that are connected to each other. The first hole 1221 is close to the bottle mouth, the second hole 1222 is close to the oil tank 13, and the cross-sectional area of ​​the first hole 1221 is smaller than the cross-sectional area of ​​the second hole 1222 so that a limited step surface 1223 is formed at the connection between the first hole 1221 and the second hole 1222. The limited step surface 1223 is used to limit one end of the leakage-proof component 15.

[0050] In the first embodiment, the fixing ring 16 seals the leak-proof member 15 on the limiting step surface 1223 along the axial direction, so that the leak-proof member 15 seals and separates the first hole 1221 and the second hole 1222 through the fixing ring 16 .

[0051] In the second embodiment, the fixing ring 16 seals the leak-proof member 15 to the inner wall of the second hole 1222 in the radial direction, so that the leak-proof member 15 seals and separates the first hole 1221 and the second hole 1222 through the fixing ring 16 .

[0052] In the third embodiment, the fixing ring 16 not only seals the leak-proof member 15 to the limiting step surface 1223 in the axial direction, but also seals the leak-proof member 15 to the inner wall of the second hole 1222 in the radial direction, so that the leak-proof member 15 can seal and separate the first hole 1221 and the second hole 1222 through the fixing ring 16.

[0053] Furthermore, the leak-proof member 15 has a first end face 151 and a second end face 152 arranged opposite to each other in the axial direction. The fixing ring 16 includes a ring end face 161 and a ring side face 162 connected to each other, and the ring end face 161 is connected to the side face at a certain angle. Preferably, the angle between the ring end face 161 and the ring side face 162 is 90 degrees.

[0054] When the leakage-proof component 15 is installed in the second hole 1222, the first end face 151 abuts against the limiting step face 1223, and the ring end face 161 abuts against the second end face 152, so that the first end face 151 and the second end face 152 of the leakage-proof component 15 which are axially opposite to each other are limited and sealed in the second hole 1222.

[0055] Furthermore, the first end face 151 and the second end face 152 may be two end faces of the first sealing portion 153 that are opposite to each other along the axial direction. The first sealing portion 153 is sealedly connected in the second hole 1222 so that the second sealing portion 154 that is sealedly connected to the first sealing portion 153 seals the oil outlet hole 122.

[0056] Furthermore, the annular side surface 162 compresses and seals the leak-proof member 15 radially against the inner side wall of the second hole 1222. That is, the annular side surface 162 cooperates with the inner side wall of the second hole 1222 to limit and seal the first sealing portion 153 away from the bottle mouth, so that when the oil bottle 10 is installed upside down in the atomizer body, the second sealing portion 154 that is pressed and torn will not drive the first sealing portion 153 limited in the second hole 1222 to move, thereby allowing the leak-proof member 15 to remain sealed and connected in the second hole 1222.

[0057] Furthermore, when the oil bottle 10 is installed upside down in the atomizer body, the oil guide tube 21 is used to press and tear the second sealing portion 154 to form a crack and pass through the crack. At the same time, under the elastic recovery effect of the second sealing portion 154, the second sealing portion 154 will return to the center direction and seal on the outer side wall of the oil guide tube 21, so that the tobacco oil in the oil bottle 10 can only flow outward from the inside of the oil guide tube 21.

[0058] Furthermore, an annular guide slope 123 is formed at one end of the bottleneck 121 near the bottle mouth. When the oil bottle 10 is installed upside down in the atomizer body, the oil guide tube 21 will press the second sealing part 154 more accurately and quickly under the action of the annular guide slope 123 and tear the second sealing part 154 so that the second sealing part 154 is sealed and connected to the outer wall of the oil guide tube 21.

[0059] By installing the leak-proof member 15 in the second hole 1222 , it can be prevented that when the oil bottle 10 is installed upside down in the atomizer body, the oil guide tube 21 directly presses against the fixing ring 16 , causing the leak-proof member 15 to fail to effectively seal in the bottleneck.

[0060] In one embodiment, the first bottle body 11 is plugged and engaged with the second plugging portion 124 of the second bottle body 12 through the first plugging portion 111. The first plugging portion 111 has a plurality of latching positions 112, and the second plugging portion 124 has a matching latching portion 125 corresponding to each latching position 112.

[0061] When the plurality of engaging portions 125 are respectively engaged with the corresponding engaging positions 112 , the first inserting portion 111 is inserted into the second inserting portion 124 so that the first bottle body 11 and the second bottle body 12 are connected to form the oil tank 13 .

[0062] When the oil tank 13 needs to be refilled with e-liquid or replaced with other types / flavors of e-liquid, the first bottle body 11 and the second bottle body 12 are separated so that the bottle bodies are opened, and the e-liquid can be replaced or refilled.

[0063] Further, the second bottle body 12 includes a first abutting portion 127 extending radially outward, and when the second bottle body 12 is inserted into the first bottle body 11, the open end 232 of the first bottle body 11 abuts against the first abutting portion 127. By providing the first abutting portion 127, when the first bottle and the second bottle body 12 are plugged together, the first abutting portion 127 can be used to limit the position, and react to the first plugging portion 111 and the second plugging portion 124, so that the first plugging portion 111 and the second plugging portion 124 can be plugged together more stably.

[0064] In one embodiment, a sealing groove 126 is formed on the outer side wall of the second plug-in portion 124, and the sealing member 14 is disposed in the sealing groove 126. When the second plug-in portion 124 is inserted into the first plug-in portion 111, the sealing member 14 is sealed between the first plug-in portion 111 and the second plug-in portion 124, thereby preventing the oil in the oil tank 13 from leaking.

[0065] In another embodiment, the first bottle body 11 is threadedly connected to the second bottle body 12, so that the first bottle body 11 and the second bottle body 12 can be quickly disassembled.

[0066] In this embodiment, the sealing member 14 can be directly sleeved on the external threaded portion of the first bottle body 11 or the second bottle body 12, and after the first bottle body 11 and the second bottle body 12 are threadedly connected, the sealing member 14 can be directly locked and sealed at the connection between the first bottle body 11 and the second bottle body 12.

[0067] Furthermore, the sealing member 14 is a sealing ring, and the sealing ring can be made of a material with elastic recovery ability such as rubber or silicone.

[0068] Furthermore, the outer wall structure of the bottleneck 121 is formed with an external thread 1211. The oil bottle 10 further includes a bottle cap 17, and the bottle cap 17 is provided with an internal thread 171 corresponding to the external thread 1211, and the bottle cap 17 is threadedly connected with the external thread 1211 on the bottleneck 121 through the internal thread 171.

[0069] When the oil bottle 10 is not installed on the atomizer body, the bottle cap 17 can be placed on the bottleneck 121 to further prevent the oil in the oil bin 13 from leaking and prevent external pollutants from entering the oil outlet 122 and / or the oil bin 13.

[0070] Furthermore, the atomizer body further comprises a mounting seat 22 and a housing 23. The mounting seat 22 is disposed in the housing 23, and a mounting hole 221 and a clamping protrusion 222 are formed on the mounting seat 22. The housing 23 is formed with a mounting cavity 231, and the mounting cavity 231 has an open end 232 for inserting the oil bottle 10.

[0071] The bottleneck 121 is also structured to form a clamping groove 128. The end of the first bottle body 11 away from the second bottle body 12 is also provided with a second abutting portion 113. When the oil bottle 10 is inverted and installed in the installation cavity 231, the clamping groove 128 and the clamping portion 125 are limitedly clamped, and the second abutting portion 113 abuts against the open end 232 of the installation cavity 231, so that the oil bottle 10 is limitedly inserted into the atomizer body.

[0072] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0073] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of this application.

[0074] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
