Description

Technical Field

[0001] The present application belongs to the technical field of electronic cigarettes, and more specifically, relates to an oil tank structure and an electronic cigarette that can extend the service life of the oil. Background Art

[0002] Currently, most electronic cigarettes have an oil tank. The ceramic atomizer core of the electronic cigarette is set in the oil tank. The ceramic atomizer core is connected to an air duct connected to the outside world. When in use, the ceramic atomizer core instantly heats the surrounding oil to atomize it, and the atomized oil flows out along the air duct. Since the oil in the oil tank has fluidity and thermal conductivity, the oil in the oil tank is heated in addition to the part near the ceramic atomizer core. The oil in other positions will also be heated. If the oil is heated repeatedly and the intervals last for a long time, there is a greater probability of chemical reactions such as decomposition, which will cause the oil to deteriorate and produce harmful substances, making the shelf life of the oil shorter, which also leads to the current short service life of electronic cigarettes after they are used. Summary of the Invention

Detailed implementation manners

[0028] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0029] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0030] It should be understood that the orientation or positional relationship indicated by the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present application.

[0031] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "multiple" is two or more, unless otherwise clearly defined. Please refer to Example 1. Figures 1 to 7 , an oil tank structure, comprising: a housing 1, a working tank 16 and an oil storage tank 15 are provided in the housing 1; a lower sealing seat 10 is provided at the lower end of the working tank 16, the lower sealing seat 10 is connected to an atomizing device 6, the atomizing device 6 is connected to an air guide 4 for guiding the atomized smoke oil, one end of the air guide 4 extends out of the housing 1; see Figure 2 、 Figure 4 、 Figure 5 A connecting space and a switch unit for controlling the opening and closing of the connecting space are provided between the working chamber 16 and the oil storage chamber 15; a control unit for controlling the switch unit is connected to the outside of the housing 1.

[0032] Since most electronic cigarettes currently have only one oil tank, during use, the non-atomized oil is affected by heating, resulting in a limited shelf life. However, the embodiment of the present application uses two tank spaces, a working tank 16 and an oil storage tank 15. During operation, only the oil in the working tank 16 is affected, resulting in a shorter shelf life, such as 1 day, 2 days, 1 week, etc. The oil in the oil storage tank 15 is basically not affected because it is isolated from the working tank 16. This can extend the shelf life of the oil and thus extend the service life of the electronic cigarette.

[0033] During use, the control unit first operates the switch unit to isolate the connecting space; the smoke oil in the working chamber 16 is isolated from the smoke oil in the oil storage chamber 15; the atomizer 6 first consumes the smoke oil in the working chamber 16. When the smoke oil in the working chamber 16 is consumed or consumed to a certain level, the control unit operates the switch unit to open the connecting space, and the smoke oil in the oil storage chamber 15 enters the working chamber 16 through the connecting space. It should be noted that if the oil storage chamber 15 is located above the working chamber 16, the electronic cigarette can be placed upright and the switch unit is turned on; if the oil storage chamber 15 is located below the working chamber 16, the electronic cigarette needs to be inverted before the switch unit is turned on. The smoke oil passes through the connecting space from the oil storage chamber 15 to the working chamber 16 under its own gravity. When the smoke oil in the working chamber 16 reaches a certain level or is full, the switch unit is turned off. It should also be noted that the smoke oil atomizer 6 and the air guide tube 4 are both prior art, which have been described in many relevant journals or patent documents. The applicant will not elaborate on them here.

[0034] Secondly, it should be noted that when setting up the working chamber 16, generally, the usage amount for 1-2 days is set, and the oil storage chamber 15 is set with a relatively large amount of e-liquid according to the size of the electronic cigarette. Therefore, the volume of the working chamber 16 is relatively small, while the volume of the oil storage chamber 15 is relatively large. The oil storage chamber 15 can be arranged above, below or on one side of the working chamber 16. When injecting e-liquid from the oil storage chamber 15 into the working chamber 16, the position of the electronic cigarette can be adjusted according to the position of the oil storage chamber 15 to make the oil storage chamber 15 located above the working chamber 16. Then, turn on the switch unit, and under the action of its own gravity, the e-liquid flows from the oil storage chamber 15 into the working chamber 16. After the injection is completed, turn off the switch unit.

[0035] See Figure 1 , Figure 2 and Figure 3 , Figure 5 ; In this embodiment, the working chamber 16 is located below the oil storage chamber 15, and a partition 14 is provided between the working chamber 16 and the oil storage chamber 15. The atomizing device 6 is provided with a fog guiding shell, and a guiding pipe 61 is formed at the upper end of the fog guiding shell. The partition 14 is provided with a protrusion 12 that cooperates with the guiding pipe 61. A jack is correspondingly formed below the protrusion 12, and the guiding pipe 61 is inserted into the jack. A through hole is provided at the upper end of the protrusion 12, and an enlarged portion 42 is provided at the lower end of the air duct 4. The enlarged portion 42 is sleeved outside the protrusion 12 and is rotatably connected to the protrusion 12; a sealing cover 2 is provided at the upper end of the housing 1, and a through hole 22 that cooperates with the air duct 4 is provided on the sealing cover 2; the upper end of the air duct 4 passes through the through hole 22 and is connected to the control unit, and the control unit can drive the air duct 4 to rotate; the communication space includes a lower communication hole 13 provided on the partition 14, and a partition piece 43 for partitioning the communication space extends outward from the side surface of the enlarged portion 42, and the partition piece 43 is the switch unit.

[0036] For the convenience of setting the switch unit and the communication space; in this embodiment, the oil storage chamber 15 is arranged above the working chamber 16, and a partition 14 is arranged therebetween. A lower communication hole 13 is provided on the partition 14, and the lower communication hole 13 can separately form the communication space; at the same time, the lower communication hole 13 is near the protrusion 12 of the partition 14 and is located below the partition piece 43; during normal operation, the atomizing device 6 atomizes the e-liquid, and the atomized e-liquid enters the fog guiding shell and the upper guiding pipe 61 above, passes through the through hole above the protrusion 12 and enters the air duct 4, and then enters the mouthpiece 71 and the human mouth through the air duct 4. When the working chamber 16 needs to be refueled, the control unit drives the air duct 4 to rotate, and the partition piece 43 at the lower end of the air duct 4 rotates together and moves away from the lower communication hole 13; the oil storage chamber 15 is communicated with the working chamber 16, and at this time, the e-liquid in the oil storage chamber 15 flows into the working chamber 16. When the e-liquid in the working chamber 16 reaches a certain amount, the control unit drives the air duct 4 to rotate; the partition piece 43 is located above the lower communication hole 13 to partition the working chamber 16 and the oil storage chamber 15.

[0037] See Figure 2 and Figure 5 , a gasket 5 is connected above the partition plate 14. The communication space includes an upper communication hole 51 provided in the gasket 5. The upper communication hole 51 communicates with the lower communication hole 13. The partition piece 43 is located above the upper communication hole 51 and abuts against the gasket 5.

[0038] Since it is difficult to seal between the partition piece 43 and the partition plate 14, a gasket 5 needs to be designed to separate the oil storage chamber 15 and the working chamber 16. In the embodiment of the present application, the gasket 5 is used for sealing and partitioning. The gasket 5 can be made of materials such as rubber and silica gel, which will not be elaborated here as it is prior art; the gasket 5 is connected to the surface of the partition plate 14, and its size and shape are the same as those of the partition plate 14; the partition piece 43 abuts against the gasket 5 and is located above the upper communication hole 51. When it is necessary to fill the working chamber 16 with oil, the control unit rotates the air guide pipe 4 and the partition piece 43, and the partition piece 43 leaves the communication hole. The e-liquid in the oil storage chamber 15 passes through the communication hole and the communication space and enters the working chamber 16. When the e-liquid in the working chamber 16 is filled to a certain extent, the control unit is driven to rotate the air guide pipe 4 and the partition piece 43 until the partition piece 43 is located above the upper communication hole 51 and separates the working chamber 16 and the oil storage chamber 15. As can be seen from the attached Figure 5 It can be seen that the communication space includes the upper communication hole 51 and the lower communication hole 13. Secondly, a socket hole 52 for sleeving with the protrusion 12 is provided in the middle of the gasket 5 to facilitate connection with the protrusion 12.

[0039] Furthermore, a sealing convex block 27 for sealing the upper end of the oil storage chamber 15 extends downward from the lower end of the sealing cover 2. A limiting piece 41 is provided in the middle of the air guide pipe 4, and the limiting piece 41 abuts against the lower end surface of the sealing convex block 27.

[0040] The lower end of the air guide pipe 4 needs to abut against the gasket 5 to seal the communication hole and separate the oil storage chamber 15 and the working chamber 16; therefore, the air guide pipe 4 cannot move upward to cause it to separate from the gasket 5; for this reason, in the embodiment of the present application, a limiting piece 41 is provided in the middle of the air guide pipe 4, and the limiting piece 41 abuts against the sealing cover 2; thereby restricting the upward movement of the air guide pipe 4; when the limiting piece 41 is specifically arranged, it is arranged as a limiting ring, and the limiting ring is integrally formed with the air guide pipe 4.

[0041] Secondly, when the air guide pipe 4 rotates, the upper end of the air guide pipe 4 rubs against the sealing cover 2, and the partition piece 43 at the lower end of the air guide pipe 4 rubs against the gasket 5; in order to enable the air guide pipe 4 to rotate flexibly with less friction; See Figure 5In the embodiment of the present application, two sealing convex rings 26 are provided on the side wall of the through hole. The two sealing convex rings 26 are connected with the air guide tube 4 to maintain the sealing performance. In the embodiment of the present application, a circular concave hole is provided on the lower end surface of the sealing convex block 27 to cooperate with the limit plate 41. The bottom surface of the circular concave hole is also provided with two sealing convex rings 26, which are against the limit plate 41. Figure 2 The sealing gasket 5 is provided with a lower recessed hole 53 that cooperates with the partition piece 43. The bottom surface of the lower recessed hole 53 is provided with a first convex ring 54 that cooperates with the protrusion 12, and a second convex ring 55 that cooperates with the communicating hole. The first convex ring 54 is located on the outside of the protrusion 12, and the second convex ring 55 is located on the outside of the communicating hole. The partition piece 43 abuts against the first convex ring 54 and the second convex ring 55.

[0042] By placing the two sealing protrusions 26, the first protrusion 54, and the second protrusion 55 at the two locations described above, the contact area between the upper end of the air duct 4 and the sealing protrusion 27 is minimized, and the contact area between the lower end and the sealing gasket 5 is also minimized, effectively reducing friction. The sealing cover 2 can be made of materials such as rubber and silicone.

[0043] Thirdly, in the embodiment of the present application, the partition piece 43 is designed as a partition ring with a connecting hole 44 provided thereon that mates with the connecting hole. As the partition piece 43 rotates with the air duct 4, when the connecting hole 44 connects with the connecting hole, smoke oil can flow from the oil storage tank 15 into the working tank 16. When the connecting hole 44 and the connecting hole are misaligned, the partition piece 43 seals the connecting space. Secondly, as an equivalent design to the partition piece 43, the partition piece 43 is a circular ring with a central angle of 30-60 degrees.

[0044] In this embodiment, an air inlet structure for connecting the working chamber 16 with the outside is provided in the housing 1 .

[0045] When the working chamber 16 is working, the atomizing device 6 atomizes the surrounding smoke oil and guides it out from the air duct 4; the smoke oil inside the working chamber 16 gradually decreases during use. When the temperature returns to normal temperature, the internal pressure will decrease and be lower than the external air pressure, which will affect the smoke oil entering the atomizing device 6 and the discharge of the atomized smoke oil; secondly, when the smoke oil in the oil storage tank 15 enters the working chamber 16, the air pressure in the oil storage tank 15 will also decrease. Over time, the air pressure in the oil storage tank 15 will be very low, which will seriously affect the smoke oil in the oil storage tank 15 from entering the working chamber 16 in the later stage. In order to improve this situation, the embodiment of the present application adopts an air duct structure connected to the working chamber 16 and connected to the outside world, so as to connect the space inside the working chamber 16 with the external space.

[0046] See also Figure 4 、 Figure 5, the air intake structure includes an air pipe 11 connected to the partition 14. The air pipe 11 is in communication with the working chamber 16. The sealing cover 2 is provided with a communication groove 25 communicating with the outside. The upper end of the air pipe 11 is in communication with the communication groove 25.

[0047] In specific implementation, when a part of the e-liquid in the working chamber 16 is vaporized and led out from the air guide pipe 4, the air pressure in the working chamber 16 decreases, and the external gas enters the working chamber 16 along the communication groove 25 and the air pipe 11 to balance the internal air pressure. Secondly, to prevent the e-liquid in the working chamber 16 from flowing out of the air pipe 11, in the embodiment of the present application, the inner diameter of the air pipe 11 is very small, such as less than 2 mm; so that the surface tension of the e-liquid in the air pipe 11 is relatively large, and thus the e-liquid entering the air pipe 11 will not leak out.

[0048] Furthermore, the sealing cover 2 is provided with an oil injection hole 21.

[0049] Currently, the lifespan of e-cigarettes is mainly limited by the total amount of e-liquid and the shelf life of the e-liquid. The present application combines the oil storage chamber 15 and the working chamber 16, so that the e-liquid in the working chamber 16 is all within the shelf life. Therefore, the lifespan of the e-cigarette applied in the present application is limited by the total amount of e-liquid. The embodiment of the present application adopts the oil injection hole 21 provided on the sealing cover 2, so that the e-liquid inside the oil storage chamber 15 can be replenished, and further the lifespan of the e-cigarette is no longer limited by the total amount of e-liquid. The service life of the e-cigarette can be extended.

[0050] See Figure 3 , the sealing cover 2 is provided with a receiving hole 24 for receiving the upper end of the air pipe 11. One end of the communication groove 25 is in communication with the receiving hole 24, and the other end of the communication groove 25 is in communication with the oil injection hole 21.

[0051] Considering that additionally providing a ventilation hole on the sealing cover 2 to connect with the communication groove 25 will result in poor sealing performance of the oil storage chamber 15. For this reason, the embodiment of the present application uses the oil injection hole 21 as a ventilation hole. The communication groove 25 is arranged on the lower end surface of the sealing cover 2. The communication groove 25 can be curved or in an L-shaped broken line, etc. When in use, air can enter from the oil injection hole 21, then enter the receiving hole 24 along the communication groove 25, and finally enter the air pipe 11. When in use, the oil injection hole 21 is connected with a plug 91 for sealing. When it is necessary to inject e-liquid into the working chamber 16, the plug 91 can be opened.

[0052] Secondly, another structure can also be adopted: The sealing cover 2 is provided with a ventilation hole. The ventilation hole is located at one end of the communication groove 25, and the upper end of the air pipe 11 is inserted into the other end of the communication groove 25. The air pipe 11 is directly connected to the ventilation hole, and the gas directly enters the air pipe 11 through the ventilation hole. The structure is also relatively simple.

[0053] SeeFigure 1 , Figure 2 and Figure 5 , the control unit includes an operation block 3. A sleeve hole 32 matching the upper end of the air duct 4 is provided in the middle of the operation block 3. The operation block 3 is sleeved with the air duct 4 and can drive the air duct 4 to rotate.

[0054] Preferably, the cross-section of the upper end of the air duct 4 is polygonal, and the cross-section of the sleeve hole 32 is also a corresponding polygon. More preferably, an operation handle 33 is connected to the side of the operation block 3. Further, a notch 23 is provided on one side of the sealing cover 2, and a convex block is formed on the other side of the sealing cover 2. The operation block 3 is arranged in the notch 23. A thickening portion 32 is provided on the side of the operation block 3 away from the convex block. When the operation block 3 drives the air duct 4 to rotate until one end of the thickening portion 32 abuts against the convex block, the partition piece 43 seals the communication space; when the operation block 3 drives the air duct 4 to rotate until the other end of the thickening portion 32 abuts against the convex block, the communication space connects the working chamber 16 and the oil storage chamber 15, and the working chamber 16 is connected to the oil storage chamber 15.

[0055] In the embodiment of the present application, the control unit is set as the operation block 3 controlled manually. Of course, it can also be set as the operation block 3 driven by a motor. When the manual operation block 3 is adopted, the operation block 3 needs to drive the air duct 4 to rotate. For convenient driving, in the embodiment of the present application, a polygonal structure is adopted, that is, the cross-section of the air duct 4 is set as a polygon, and the sleeve hole 32 of the operation block 3 is also polygonal. When the operation block 3 rotates, it can drive the air duct 4 to rotate. Of course, the shape of the sleeve hole 32 can also be other shapes, such as oval, etc.; secondly, as an equivalent deformation, the sleeve hole 32 can also be circular, the air duct 4 is tubular, the outer diameter of the air duct 4 is greater than or equal to the inner diameter of the sleeve hole 32, and the operation block 3 is connected with the air duct 4 in a fitting connection or an interference fit connection, and the operation block 3 can also be driven to rotate the sleeve.

[0056] For convenient operation of rotating the operation block 3, in the embodiment of the present application, an operation handle 33 is connected to the side of the operation block 3. The operation handle 33 and the operation block 3 can be integrally formed, or can be fixedly connected by bonding, welding, etc.; when the air duct 4 is rotated by the operation block 3, it is necessary to know at which angle the air duct 4 rotates so that the oil storage chamber 15 is partitioned or communicated with the working chamber 16. Therefore, in the embodiment of the present application, the method of restricting the rotation angle of the operation block 3 is adopted. Specifically: a thickening portion 32 is provided on the side of the operation block 3 away from the convex block. The thickening portion is used to limit the rotation angle of the operation block 3. When the operation block 3 is driven to rotate, when the operation block 3 rotates clockwise, one end of the thickening portion 32 will abut against the convex block, and when it rotates counterclockwise, the other end of the thickening portion 32 will abut against the convex block. The air duct 4 follows the operation block 3 to rotate to the above two positions, and the partition piece 43 connected to the lower end of the air duct 4 corresponds to partitioning the communication hole and being misaligned with the communication, so that it can be sensed how to operate the operation block 3 to realize the function of the partition piece 43.

[0057] Embodiment 2: Refer to Figure 6 and Figure 7 ; An electronic cigarette, including the above oil storage structure, a sleeve 8 is sleeved outside the housing 1; a pressing plate 9 is provided at the upper end of the sealing cover 2, a hollow hole matching the air guide tube 4 is provided on one side of the pressing plate 9, and a plug 91 matching the oil injection hole 21 is provided at the lower end of the other side of the pressing plate 9; the upper end of the sleeve 8 is detachably connected with a top cover 7, a mouthpiece 71 communicating with the air guide tube 4 is provided on one side of the top cover 7, and the top cover 7 abuts against the upper end surface of the pressing plate 9.

[0058] By setting the above-mentioned chamber structure in the electronic cigarette, the service time of the electronic cigarette can be longer when in use; when the oil storage chamber 15 needs to be filled with e-liquid, first remove the top cover 7, and then take out the pressing plate 9, then the oil injection hole 21 can be exposed, and at this time, e-liquid can be injected into the oil injection hole 21. When it is necessary to inject e-liquid into the working chamber 16, operate the operating handle 33 to rotate it from one side to the other side. For the convenience of description, the two sides are respectively the closed side and the open side, that is, rotate the operating handle 33 from the closed side to the open side; the operating block 3 drives the air guide tube 4 to rotate, and the partition piece 43 at the lower end of the air guide tube leaves the communication hole, and the oil storage chamber 15 communicates with the working chamber 16, and the e-liquid flows from the oil storage chamber 15 into the working chamber 16. At this time, if the e-liquid flow is difficult, the top cover 7 and the pressing plate 9 can be opened to inject some air into the working chamber 16. When the e-liquid injection in the working chamber 16 reaches a certain level or is full, rotate the operating handle 33 from the open side to the closed side, and the air guide tube 4 drives the partition piece 43 to rotate to seal the communication hole, separating the working chamber 16 and the oil storage chamber 15.

[0059] Secondly, an activity groove 81 matching the operating handle 33 is provided on the upper side surface of the sleeve 8 to expose the operating handle 33 and limit the movement range of the operating handle 33 for convenient operation. A circuit board and a battery for supplying power to the circuit board are also provided in the housing 1. A part of the circuit board is embedded in the lower sealing seat 10 and electrically connected to the atomizing device 6. The lower sealing seat 10 can be made of rubber or other materials and is used to seal the lower end of the working chamber 16; this is the prior art and will not be elaborated here.

[0060] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present application shall be included in the protection scope of the present application.
