Oil guide structure

Abstract

The utility model discloses an oil guide structure. According to the oil bottle, the anti-leakage piece is arranged in the first oil outlet hole communicated with the oil bin, and the second central axis of the anti-leakage piece coincides with the first central axis of the first oil outlet hole, so that when the oil bottle is installed on the installation base, the anti-leakage piece is arranged in the first oil outlet hole, and the second central axis of the anti-leakage piece coincides with the first central axis of the first oil outlet hole; when the oil guide pipe is pressed against the leakage-proof part, the leakage-proof part is cracked and is sealed on the outer side wall of the oil guide pipe, so that tobacco tar in the oil bottle is prevented from flowing out of the outer side wall of the oil guide pipe, and meanwhile, a third central axis of the oil guide pipe coincides with the first central axis and the second central axis; therefore, the oil guide pipe can evenly and stably abut against the leakage-proof piece, and the situation that the leakage-proof piece cannot be effectively sealed on the outer side wall of the oil guide pipe in the process of installing the oil bottle is avoided. After installation is completed, tobacco tar in the tar bottle can evenly and stably flow along the interior of the tar guide pipe.

Description

Technical Field

[0001] The present application relates to the technical field of atomizers, and in particular to an oil guide structure. 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] For the oil bottle installed upside down in the atomizer body (i.e., the mouth of the oil bottle faces the opposite direction to the atomizer mouthpiece), a puncture piece is required to puncture the sealing film of the mouth of the oil bottle so that the oil in the oil bottle can flow to the atomizer core for atomization. In the prior art, there are two types of oil guide structures for inverted oil bottles. The first is to set a puncture column at the bottom of the mounting groove for mounting the oil bottle, and to set an oil outlet hole on one side of the puncture column. After the puncture column punctures the sealing film, the oil in the oil bottle will flow along the puncture column into the mounting groove, and then flow along the oil outlet hole to the oil passage; the second is to set an atomizer core assembly at the central axis of the oil bottle, and puncture the sealing film through an oil guide tube that deviates from the central axis and is located at the atomizer core assembly. After puncturing, the oil in the oil bottle flows to the oil outlet hole through the inside of the oil guide tube to the oil passage. In the above two oil guide structures, the puncture member (puncture column, oil guide tube) does not puncture from the center of the sealing film, that is, the puncture member does not puncture at the central axis of the sealing film. Therefore, in the existing inverted oil guide structure, when the oil bottle is installed upside down, when the puncture member punctures the sealing film, the force on the sealing film is not uniform and stable, resulting in the risk of the sealing film falling off during the puncture process. After the oil bottle is installed, the smoke oil in the oil bottle cannot flow out evenly and stably. Utility Model Content

In all examples shown and discussed here, any specific value should be interpreted as being merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, and therefore, once a certain item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.

[0041] See also Figure 1-11As shown, the present application provides an oil guide structure, which includes an oil bottle 10, a leak-proof member 15 and an oil guide tube 30. The leak-proof member 15 is arranged in the oil bottle 10 to prevent the oil contained in the oil bottle 10 from leaking. When the oil bottle 10 is invertedly installed on the atomizer body, the oil guide tube 30 arranged on the atomizer body can press against the leak-proof member 15 and tear the leak-proof member 15, so that the leak-proof member 15 is sealed with the outer wall of the oil guide tube 30, so that the oil contained in the oil bottle 10 can flow evenly and stably along the inside of the oil guide tube 30.

[0042] Furthermore, when the oil bottle 10 is installed on the atomizer body, the oil bottle 10 , the leak-proof member 15 and the oil guide tube 30 are located on the same axis, so that the oil in the oil bottle 10 can flow more evenly and stably along the inside of the oil guide tube 30 .

[0043] Furthermore, the oil bottle 10 has an oil tank 13 and a first oil outlet 122. The first oil outlet 122 is connected to the oil tank 13, and the first oil outlet 122 has a first central axis 1224.

[0044] The leak-proof member 15 is disposed in the first oil outlet 122 to prevent the oil in the oil bin 13 from leaking. The leak-proof member 15 has a second central axis 155 , and the second central axis 155 coincides with the first central axis 1224 .

[0045] The oil guide tube 30 is disposed on the mounting seat 20 and has a third central axis 31. When the oil bottle 10 is mounted on the mounting seat 20, the oil guide tube 30 extends into the first oil outlet hole 122 and presses against the leak-proof member 15 so that the leak-proof member 15 is broken and sealed on the outer wall of the oil guide tube 30. At this time, the third central axis 31 coincides with the first central axis 1224 and the second central axis 155. Thus, the tobacco oil in the oil bottle 10 can flow evenly and stably along the inside of the oil guide tube 30.

[0046] Furthermore, since the third center axis 31 of the oil guide tube 30 coincides with the second center axis 155 of the first oil outlet hole 122 and the first center axis 1224 of the leakage prevention component 15, during the process of installing the oil bottle 10 on the mounting seat 20, the oil guide tube 30 can apply a pressing force to the leakage prevention component 15 evenly and stably, thereby preventing the leakage prevention component 15 from falling off from the first oil outlet hole 122 due to uneven pressing force, and preventing the leakage prevention component 15 from being unable to effectively seal on the outer wall of the oil guide tube 30 after being torn by pressing, causing the tobacco oil to flow out of the outer wall of the oil guide tube 30.

[0047] Furthermore, the oil guide pipe 30 includes a pressing section 32, an oil outlet section 33 and a mounting section 34. The oil outlet section 33 is connected between the pressing section 32 and the mounting section 34. The pressing section 32 has an oil inlet hole 321, and the oil outlet section 33 has an oil through hole 331. When the oil bottle 10 is mounted on the mounting seat 20, the tobacco oil in the oil tank 13 enters the oil guide pipe 30 through the oil inlet hole 321, and flows in the oil guide pipe 30 until it flows out from the oil through hole 331.

[0048] The mounting seat 20 includes a mounting hole 22, a buffer cavity 23, and a second oil outlet hole 24. The mounting section 34 is disposed in the mounting hole 22, and can realize fixed installation of the oil guide pipe 30 through the mounting hole 22. The oil hole 331 is in communication with the buffer cavity 23, and the second oil outlet hole 24 is in communication with the buffer cavity 23.

[0049] When the oil bottle 10 is installed upside down on the mounting seat 20, the pressing section 32 presses the leak-proof component 15 to cause the leak-proof component 15 to rupture and seal on the outer wall of the pressing section 32. At this time, the tobacco oil in the oil tank 13 will flow through the oil guide pipe 30 and enter the buffer cavity 23 from the oil hole 331 and then flow out from the second oil outlet hole 24.

[0050] Since the oil bottle 10 is invertedly mounted on the mounting base 20, the oil in the oil bottle 10 will flow downward rapidly through the oil guide pipe 30 under the action of gravity. In order to prevent the oil from directly rushing to the atomizing assembly 60 of the atomizer body, resulting in an excessive amount of oil supply, the buffer chamber 23 can be provided to effectively buffer the oil, so as to prevent the amount of oil stored in the oil storage cotton 50 from being too large, resulting in an excessive amount of oil supplied to the atomizing assembly 60 through the oil storage cotton 50.

[0051] Furthermore, the oil guide structure further includes a base 40, and the mounting seat 20 is disposed on the base 40. A mounting column 41 is formed on the base 40, and the mounting hole 22 is a through hole.

[0052] The mounting section 34 passes through the through hole and is sealed and plugged onto the mounting column 41 , so that the opening of the oil guide pipe 30 at one end of the mounting section 34 is sealed and the oil guide pipe 30 can be accurately positioned and quickly installed through the mounting column 41 , as well as stably supported.

[0053] In order to prevent the smoke oil in the buffer cavity 23 from flowing from the mounting hole 22 to the base 40 and causing inverted smoke oil leakage, the outer wall of the mounting section 34 is sealedly connected to the mounting seat 20 corresponding to the mounting hole 22, so that the smoke oil in the buffer cavity 23 can only flow from the second oil outlet hole 24 to the oil storage cotton 50.

[0054] In one embodiment, the end face of the pressing section 32 away from the oil outlet section 33 is an elliptical ring structure, so that when the oil guide pipe 30 presses against the leakage prevention component 15, it can be easier and convenient for the ruptured leakage prevention component 15 to be more tightly sealed on the outer wall of the oil guide pipe 30 by relying on its own elastic recovery ability.

[0055] In another embodiment, the end face of the pressing section 32 away from the oil outlet section 33 is annular in structure, and is consistent with the end face structure of the installation section 34 away from the oil outlet section 33, so that when installing the oil guide pipe 30, any end of the oil guide pipe 30 can be selected as the installation end, and the other end as the pressing section 32.

[0056] Furthermore, the oil bottle 10 comprises a bottleneck 121. The outer wall structure of the bottleneck 121 is formed with a first limiting portion 128, and the mounting seat 20 is formed with a second limiting portion 21 adapted to the first limiting portion 128.

[0057] When the oil bottle 10 is installed on the mounting seat 20 , the first limiting portion 128 and the second limiting portion 21 limit each other, so that the oil bottle 10 can be stably installed on the mounting seat 20 .

[0058] In one embodiment, the first limiting portion 128 may be an external thread structure, and the second limiting portion 21 may be an internal thread structure adapted to the external thread structure, so that the oil bottle 10 and the mounting seat 20 may be threadedly connected.

[0059] In another embodiment, the first limiting portion 128 is a clamping groove, and the second limiting portion 21 is a limiting protrusion. By pressing the oil bottle 10, the limiting protrusion can be limited in the clamping groove, thereby preventing the oil bottle 10 from moving in the axial direction of the first central axis 1224.

[0060] Further, the oil bottle 10 is a detachable split oil bottle 10, and the oil bottle 10 includes a first bottle body 11, a second bottle body 12, a sealing member 14, and the leak-proof member 15. The second bottle body 12 is detachably connected to the first bottle body 11 to form the oil tank 13 and the first oil outlet 122, and the oil tank 13 is connected to the first 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.

[0061] 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 residual oil on the inner wall of the oil tank 13 when the disposable oil bottle 10 is discarded, the detachable and reusable oil bottle 10 can also significantly reduce the waste of oil caused by residual oil, thereby improving the utilization rate of the oil.

[0062] 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.

[0063] Furthermore, 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 that is pressed and torn by the oil guide tube 30 can rely on the elastic recovery ability to return to the outer side wall of the corresponding oil guide tube 30 and seal on the outer side wall of the oil guide tube 30, so that the tobacco oil in the oil bottle 10 can only flow outward from the inside of the oil guide tube 30, but cannot flow outward from between the leak-proof member 15 and the outer side wall of the corresponding oil guide tube 30.

[0064] 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 first oil outlet hole 122 via a fixing ring 16, and the second sealing portion 154 is radially sealed and connected to the first sealing portion 153 and separates the first sealing portion 153 of the tubular structure.

[0065] When the oil guiding pipe 30 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 30, 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 30.

[0066] Since the second sealing portion 154 torn by the oil guide tube 30 will form a corresponding crack, and the second sealing portion 154 has elastic recovery ability, when the oil guide tube 30 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.

[0067] 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.

[0068] Furthermore, the second bottle body 12 is structured to form a bottleneck 121. The bottleneck 121 is structured to form the first 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 first oil outlet 122.

[0069] Further, the bottleneck 121 is structured to form a bottle mouth, which is an opening of the first oil outlet 122 away from one end of 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.

[0070] Furthermore, the first 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.

[0071] 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 .

[0072] 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 .

[0073] 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.

[0074] 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.

[0075] 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.

[0076] 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 first oil outlet hole 122.

[0077] 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.

[0078] Furthermore, when the oil bottle 10 is installed upside down in the atomizer body, the oil guide tube 30 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 30, so that the tobacco oil in the oil bottle 10 can only flow outward from the inside of the oil guide tube 30.

[0079] 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 30 will press the second sealing portion 154 more accurately and quickly under the action of the annular guide slope 123 and tear the second sealing portion 154 so that the second sealing portion 154 is sealed and connected to the outer wall of the oil guide tube 30.

[0080] 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 30 directly presses against the fixing ring 16 , causing the leak-proof member 15 to fail to be effectively sealed in the bottleneck 121 .

[0081] 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.

[0082] 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 .

[0083] 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 oil bottle 10 is opened, and the e-liquid can be replaced or refilled.

[0084] Further, the second bottle body 12 includes an abutment portion 127 extending radially outward, and when the second bottle body 12 is inserted into the first bottle body 11, the open end of the first bottle body 11 abuts against the abutment portion 127. By providing the abutment portion 127, when the first bottle and the second bottle body 12 are plugged together, the abutment 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.

[0085] 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.

[0086] 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.

[0087] 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.

[0088] 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.

[0089] 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.

[0090] 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.
