Description

Technical Field

[0001] The utility model relates to the technical field of electronic cigarettes, in particular to a large-capacity visible oil tank and an electronic cigarette having the same. Background Art

[0002] Electronic cigarettes are a type of atomization device that heats liquid e-liquid and converts it into smoke. When in use, e-liquid is a common consumable and needs to be added in time when it is low to ensure use. E-liquid visualization can intuitively help users add e-liquid in a timely manner.

[0003] To make the e-liquid visible, it cannot be stored completely through the oil-absorbing cotton and must remain in liquid form. Existing large-capacity visible oil tanks of electronic cigarettes with a capacity of more than 5ml generally have the risk of oil leakage. The oil pressure of liquid e-liquid storage, that is, the weight of the e-liquid itself, is too large, which will cause the sealing structure to fail or the oil storage cotton of the core part to be unable to withstand the oil pressure and easily cause oil leakage. Existing visible oil tank products will cause oil tank leakage after a period of use due to oil pressure and air negative pressure, reducing the safety of electronic cigarettes when used. Summary of the invention

[0004] In order to solve the above problems, the utility model provides a large-capacity visible oil tank, including a shell, a top cover, a bottom cover and an atomizer core. The top cover, the bottom cover and the shell are surrounded by the atomizer core to form an oil storage tank. A first partition is arranged in the oil storage tank. The first partition surrounds the atomizer core and is connected to the shell. The inner cavity formed by the first partition surrounding the atomizer core and connected to the shell is a small oil tank, and the outer cavity is a large oil tank; the oil storage tank forms a secondary oil tank in the small oil tank by a second annular partition arranged on the inner side of the small oil tank and circumferentially of the atomizer core; an overflow port is arranged on the top of the first partition, an overflow port is arranged on the bottom of the second partition, and an oil inlet hole is arranged at the bottom of the atomizer core.

[0005] In the above technical solution, the interior of the oil storage cavity is divided by a partition to form three oil cavities with decreasing space, thereby reducing the oil pressure on the atomizer core, reducing the risk of oil leakage caused by excessive oil pressure on the oil-locking cotton of the atomizer core, and solving the problem of oil leakage caused by excessive oil pressure of large capacity. The oil tank structure in the technical solution is simple, avoiding the space occupation caused by too many mechanical components and the oil leakage caused by complex structure, while reducing the difficulty of mold opening, reducing product materials, and saving production costs.

[0006] Preferably, the bottom of the large oil tank is integrally formed, and the top cover is provided with an oil filling hole on the top of the large oil tank.

[0007] The large oil tank in the oil storage tank bears the most oil storage function, and the bottom bears the greatest oil pressure. The bottom adopts an integrated molding process to avoid leakage gaps that may be caused by the bottom seal, preventing the leakage of smoke oil.

[0008] Preferably, the maximum total oil storage volume of the small oil tank and the secondary oil tank is the maximum bearing oil pressure of the atomizer core.

[0009] The secondary oil tank is the oil tank that the atomizer core is in direct contact with. Its bottom is connected to the small oil tank through an overflow port. The overall storage space size of the small oil tank and the secondary oil tank is designed based on the maximum oil pressure that the atomizer core can bear. The oil pressure is always kept in a state that the atomizer core can absorb through space control, and the liquid pressure of the secondary oil tank is further reduced through the second partition, so that the oil pressure of the secondary oil tank is very small and the oil can be evenly fed over a large area. This design allows the atomizer core to always maintain a pressure state that it can withstand, and avoids the oil leakage problem caused by the atomizer core oil lock cotton bearing excessive oil pressure to the greatest extent.

[0010] Preferably, the shell portion enclosing the small oil tank is a curved surface.

[0011] The shell part enclosing the small oil tank is an arc surface, so that when the electronic cigarette is placed flat, the shell can form a gathering effect on the oil. When the amount of oil is small, the electronic cigarette can still maintain a high liquid level of the oil by the gathering effect and transport it to the secondary oil tank to ensure the use of the electronic cigarette.

[0012] Preferably, the oil inlet holes are arranged in multiple vertical rows.

[0013] There are contradictory problems in the high-power, large-smoke, visible oil tank electronic cigarettes on the market. When the oil storage tank has a large amount of oil, the oil pressure is high, and the atomizer core has too many or too large oil inlet holes, which will lose the ability to resist negative pressure and lock oil, causing oil leakage. If the oil inlet holes are too small or few, the total area is small, which will lead to slow oil inlet and cannot meet the high power and faster oil guide problem. Through the design of three-level compartments, the atomizer core in this solution does not bear high pressure, and can realize the design of multiple rows of oil inlet holes without causing the atomizer core to lose its oil locking ability, achieving the effect of no oil leakage and high-power oiling.

[0014] Preferably, the shell is provided with a transparent visual window on the large oil tank side.

[0015] The user can visually see the remaining oil amount through the visual window on the side of the large oil tank.

[0016] Preferably, the shell is provided with a transparent visible window on the small oil tank side.

[0017] The user can visually see the amount of oil in the small oil tank through the visual window on the side of the small oil tank. When the oil in the small oil tank is insufficient, the smoke body can be turned upside down to allow the smoke oil in the large oil tank to be injected into the small oil tank through the overflow port, thereby adding smoke oil to the small oil tank and the secondary oil tank.

[0018] To solve the above problems, the utility model further provides an electronic cigarette, the structure inside the electronic cigarette includes the above large-capacity visible oil tank.

[0019] The beneficial effects of the utility model are three:

[0020] 1. Solved the risk of oil leakage caused by the gravity of the e-liquid in the large-capacity visible oil tank.

[0021] 2. The partitioned oil tank has a simple structure and can achieve large-capacity to small-area control without component assembly, preventing oil leakage caused by high oil pressure damaging the oil inlet system of the atomizer core.

[0022] 3. The partitioned oil tank and the internal secondary small oil tank can make better use of the e-liquid, prevent the problem of oil waste in the later stage of product use due to difficulty in guiding the e-liquid, and increase the service life of consumers.

[0029] In order to make the technical problems to be solved, technical solutions and advantages of the present invention more clear, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0030] Example 1

[0031] like Figure 1-4As shown, the embodiment of the utility model provides a large-capacity visual oil tank, including a shell 6, a top cover 7, a bottom cover 8 and an atomizer core 4. The top cover 7, the bottom cover 8 and the shell 6 are surrounded by the atomizer core 4 to form an oil storage tank. A first partition 9 is arranged in the oil storage tank. The first partition 9 surrounds the atomizer core 4 and is connected to the shell 6. The inner cavity formed by the first partition 9 enclosing the atomizer core 4 and connecting to the shell 6 is a small oil tank 2, and the outer cavity is a large oil tank 1; the oil storage tank forms a secondary oil tank 3 in the small oil tank by a second annular partition 10 arranged inside the small oil tank 2 and around the atomizer core 4; the top of the first partition 9 is provided with an overflow port, the bottom of the second partition 10 is provided with an overflow port, and the bottom of the atomizer core 4 is provided with an oil inlet hole 11. The bottom of the large oil tank 1 is integrally formed, and the top cover 7 is provided with an oil filling hole at the top of the large oil tank 1. The maximum total oil storage of the small oil tank 2 and the secondary oil tank 3 is the maximum oil pressure of the atomizer core 4. The shell 6 enclosing the small oil tank 2 is an arc surface. The oil inlet holes 11 are arranged in multiple vertical rows. The shell 6 is provided with transparent visual windows 5 on both sides of the large oil tank 1 and the small oil tank 2.

[0032] The smoke oil is injected into the oil storage tank through the oil filling hole at the top of the large oil tank. When the oil tank is full, it overflows to the small oil tank through the overflow port at the upper end of the first partition, and is simultaneously injected into the secondary oil tank through the overflow port at the bottom of the small oil tank and the second partition. Since the overflow ports of the small oil tank and the secondary oil tank are set at the bottom, as long as there is smoke oil in the small oil tank, it can be guaranteed that there is smoke oil in the secondary oil tank. During use, if the liquid level of the large oil tank is lower than the overflow port, the oil in the large oil tank can be inverted to allow the oil to flow into the small oil tank, and then into the secondary oil tank, ensuring that the atomizer core gets smoke oil.

[0033] In this embodiment, if Figure 3 , 4 As shown, the width of the secondary oil tank is very small, the cavity is narrow, and the height of the cavity is consistent with the height of the oil inlet hole at the bottom of the atomizer core. The height is much lower than the small oil tank, and the oil storage capacity is very small, but it can keep the oil inlet hole of the atomizer core completely immersed in the e-liquid. This design makes the liquid pressure faced by the atomizer core very small, and it can open many holes without leakage. When the gas negative pressure is generated during suction, it can efficiently absorb the e-liquid, achieving high power without oil leakage.

[0034] Figure 4 The actual height of the first partition plate 9 shown in the figure is determined according to the amount of smoke oil carried by the atomizer core in actual testing. By adjusting the height of the first partition plate 9, it can be ensured that the maximum total oil storage volume of the small oil tank 2 and the secondary oil tank 3 is equal to the maximum oil pressure carried by the atomizer core 4, thereby preventing leakage caused by excessive oil pressure carried by the atomizer core.

[0035] This design has the following three beneficial effects:

[0036] 1. Solved the risk of oil leakage caused by the gravity of the e-liquid in the large-capacity visible oil tank.

[0037] 2. The partitioned oil tank has a simple structure and can achieve large-capacity to small-area control without component assembly, preventing oil leakage caused by high oil pressure damaging the oil inlet system of the atomizer core.

[0038] 3. The partitioned oil tank and the internal secondary small oil tank can make better use of the e-liquid, prevent the problem of oil waste in the later stage of product use due to difficulty in guiding the e-liquid, and increase the service life of consumers.

[0039] Example 2

[0040] This embodiment provides an electronic cigarette, wherein the large-capacity visible oil tank in Embodiment 1 is arranged inside the electronic cigarette.

[0041] The above is a preferred embodiment of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
