[0030] The specific implementation modes of the present utility model are introduced with reference to the accompanying drawings.
[0031] refer to Figure 1 The figure is a schematic diagram of the three-dimensional structure of an electronic cigarette with a replaceable oil storage tank. The upper part of the electronic cigarette is a nozzle 11, the left side of the lower part is a battery 8, and the right side is an oil bottle 5 as an oil storage tank. The oil cup 3 inside the electronic cigarette has a small capacity of less than two milliliters. The oil bottle 5 is installed in a detachable manner. After the oil in the oil bottle 5 is filled into the oil cup 3, the empty oil bottle 5 can be removed and replaced with a new oil bottle 5, so that the electronic cigarette only needs to replace the oil bottle 5 for oil filling to be continuously used. The nozzle 11, the heating core component 9, etc. can be reused and continuously used, reducing the waste of resources and being beneficial to environmental protection.
[0032] refer to Figures 1 to 5, an electronic cigarette with a replaceable oil storage tank comprises a shell 1, a bracket 2, an oil bottle 5, an oil filling cap 6, and a battery 8. A suction nozzle 11 is arranged on the shell 1, the bracket 2 is fixed in the shell 1, and an oil cup 3 is formed between the bracket 2 and the inner wall of the shell 1, the oil bottle 5 is detachably mounted on one side of the oil cup 3, an oil filling pipe 51 of the oil bottle 5 extends to the inside of the oil cup 3, and the oil filling cap 6 is movably arranged on the shell 1, and a valve needle 61 extending into the inside of the oil cup 3 is arranged on the oil filling cap 6, and the valve needle 61 cooperates with the oil filling pipe 51 of the oil bottle 5 to control whether the oil bottle 5 is connected with the oil cup 3; in the oil filling state, the oil filling cap 6 drives the valve needle 61 to disengage from the oil filling pipe 51 to connect the oil cup 3 with the oil bottle 5; in the non-oil filling state, the valve needle 61 blocks the oil filling pipe 51 to cut off the connection between the oil cup 3 and the oil bottle 5.
[0033] The electronic cigarette with a replaceable oil storage tank in the embodiment of the present application is configured with a separate oil bottle 5 as the oil storage tank. The oil bottle 5 is detachable and can be replaced when the oil in the oil cup 3 is exhausted, so that the electronic cigarette can be reused. The oil bottle 5 controls whether to fill the oil cup 3 with oil through the valve needle 61. The use is convenient, and what is replaced and discarded is the empty oil bottle 5, which reduces the waste of resources, is beneficial to environmental protection, meets the needs of different customers, and enhances the customer experience.
[0034] In order to stably install the oil bottle 5 on one side of the oil cup 3, in this embodiment, refer to Figure 4 The oil bottle 5 is detachably connected to the bracket 2.
[0035] It can be understood that, in such a configuration, the oil cup 3 is arranged between the bracket 2 and the inner wall of the shell 1, the oil bottle 5 is connected to the bracket 2, and the bracket 2 is fixed to the inner wall of the shell 1, so that the oil bottle 5 can be stably installed on the shell 1 through the bracket 2. At the same time, it is convenient for the oil filling pipe 51 of the oil bottle 5 to extend into the oil cup 3, thereby reducing the difficulty of users to disassemble and assemble the oil bottle 5 and facilitating use.
[0036] In order to facilitate the user to disassemble and assemble the oil bottle 5, in this embodiment, refer to Figure 4 One end of the oil bottle 5 near the oil filling pipe 51 is provided with an external thread 53, the bracket 2 is provided with a mounting groove 21, the inner wall of the mounting groove 21 is provided with an internal thread 22, and the oil bottle 5 is installed on the bracket 2 through the cooperation of the external thread 53 and the internal thread 22.
[0037] It can be understood that, with such a configuration, one end of the oil bottle 5 is exposed from the shell 1, so that the user can act on the exposed part of the oil bottle 5 and realize the disassembly and assembly of the oil bottle 5 by rotating the oil bottle 5. The oil bottle 5 can be stably installed on the bracket 2 through the thread, ensuring that the oil filling tube 51 of the oil bottle 5 can stably extend into the oil cup 3 and will not easily slip out of the oil cup 3, thereby avoiding leakage of the tobacco oil in the oil cup 3.
[0038] In order to ensure the sealing performance of the oil cup 3, in this embodiment, Figure 4A sealing silicone member 4 is provided on the inner wall of the bracket 2, and the sealing silicone member 4 is sealed and connected with the inner wall of the shell 1 to form an oil cup 3. There is a plug hole 41 on the sealing silicone member 4, and the oil filling pipe 51 is inserted into the oil cup 3 from the plug hole 41. The outer wall of the oil filling pipe 51 is interference fit with the inner wall of the plug hole 41.
[0039] It is understandable that, with such a configuration, the sealing silicone component 4 is relatively soft in texture, and can achieve an interference fit with the contact portion of the shell 1 and the oil filling tube 51 through the deformation of the sealing silicone component 4 itself, thereby ensuring that the sealing silicone component 4 forms a good seal with the shell 1 and the oil filling tube 51 to avoid leakage of the smoke oil in the oil cup 3.
[0040] It should be further explained that a circle of pressing groove 43 is provided on the upper part of the sealing silicone member 4, and the end face of the bracket 2 is embedded in the pressing groove 43, so that the sealing silicone member 4 forms a U-shaped structure at the pressing groove 43, sealing the gap between the end face of the bracket 2 and the inner wall of the shell 1.
[0041] In order to facilitate the filling of oil into the oil cup 3, in this embodiment, Figure 4 and Figure 5 The oil filling cap 6 is connected to a pressure relief pipe 63, which is parallel to the valve needle 61. One end of the pressure relief pipe 63 is fixed on the oil filling cap 6 and communicates with the through hole 64 on the oil filling cap 6. The other end of the pressure relief pipe 63 extends into the oil cup 3 and cooperates with the blocking groove 42 of the sealing silicone member 4. In the oil filling state, the pipe opening of the pressure relief pipe 63 in the oil cup 3 is separated from the blocking groove 42 and communicated with the oil cup 3. In the non-oil filling state, the pipe opening of the pressure relief pipe 63 in the oil cup 3 is blocked by the blocking groove 42.
[0042] It can be understood that, with such a configuration, in the unfilled state, the oil cup 3 forms a relatively closed chamber under the sealing of the silicone seal, and under the action of the air pressure in the chamber, it is difficult for the tobacco oil in the oil bottle 5 to enter the oil cup 3. In the filled state, the oil cup 3 is connected to the external atmosphere through the pressure relief pipe 63 of the oil filling cap 6, and the gas in the oil cup 3 can be discharged through the pressure relief pipe 63, so that the tobacco oil in the oil bottle 5 can enter the oil cup 3 under gravity or extrusion, and the oil cup 3 discharges gas of a volume equal to that of the injected tobacco oil, so that the air pressure in the oil cup 3 remains stable.
[0043] In order to facilitate the discharge of gas in the oil cup 3 during oil filling, in this embodiment, Figure 5 In the oil filling state, the oil bottle 5 is inverted above the oil cup 3, and the tobacco oil in the oil bottle 5 is injected into the oil cup 3 from the oil filling pipe 51 by gravity or external pressure. The height of the pipe opening of the pressure relief pipe 63 located in the oil cup 3 is higher than the height of the oil filling hole 52 of the oil filling pipe 51 to discharge the gas in the oil cup 3.
[0044] It can be understood that, with such a configuration, by squeezing the oil bottle 5, the oil cup 3 can be quickly filled with tobacco oil, and the oil cup 3 will be gradually filled under the action of gravity. As the liquid level of the tobacco oil in the oil cup 3 gradually increases, the gas above the liquid level will be pushed to be discharged from the pressure relief pipe 63, thereby facilitating the discharge of as much gas as possible in the oil cup 3. The height of the pressure relief pipe 63 in the oil cup 3 is the height of the tobacco oil that can be added to the oil cup 3. If the added tobacco oil level is higher than the pipe mouth of the pressure relief pipe 63, the tobacco oil will flow out of the pressure relief pipe 63.
[0045] In order to ensure the sealing performance of the oil cup 3, in this embodiment, Figure 4 A silicone plug 7 is provided at the housing 1 and the oil filling cap 6. Two connecting holes 71 are provided on the silicone plug 7. The valve needle 61 and the pressure relief pipe 63 are respectively inserted into the two connecting holes 71. The outer wall of the valve needle 61 and the outer wall of the pressure relief pipe 63 are respectively interference fit with the inner walls of the two connecting holes 71.
[0046] It is understandable that, with such a configuration, the silicone plug 7 is softer in texture and can form an interference fit with the shell 1 , the pressure relief pipe 63 , and the valve needle 61 through its own deformation, thereby ensuring a good seal between the silicone plug 7 and the shell 1 , the pressure relief pipe 63 , and the valve needle 61 .
[0047] In order to stably block the oil filling pipe 51 when no oil is filled, in this embodiment, referring to the figure, one end of the valve needle 61 that cooperates with the oil filling pipe 51 is set to a conical plug 62, and the inner diameter of the oil filling hole 52 of the oil filling pipe 51 is between the minimum outer diameter and the maximum outer diameter of the plug 62.
[0048] It can be understood that, with such a configuration, the tip of the conical plug 62 can be accurately inserted into the oil filling hole 52 of the oil filling pipe 51, and the conical surface of the plug 62 can be used to guide the entire plug 62 to be gradually inserted into the oil filling hole 52 until the conical surface of the plug 62 is interference fit with the inner wall of the oil filling hole 52, thereby completely blocking the oil filling hole 52.
[0049] In order to facilitate the removal of the battery 8, in this embodiment, refer to Figure 1 and Figure 4 The housing 1 is provided with a fixing groove 12 , and the battery 8 is detachably inserted into the fixing groove 12 through a fixing frame 81 , and the fixing frame 81 is snap-connected with the housing 1 .
[0050] It can be understood that with such a configuration, the battery 8 can be replaced quickly. Due to the material problem of the battery 8 itself, the battery 8 needs to be recycled separately after use. When the electronic cigarette is damaged and cannot be used, the battery 8 can be removed and processed separately, which is beneficial to environmental protection. The battery 8 is clamped in the shell 1 through the fixing frame 81. When the battery 8 needs to be removed, it is only necessary to lift the buckle 83 to pull the fixing frame 81 and the battery 8 out of the shell 1, so that the battery 8 is separated from the shell 1, which is convenient for users to sort garbage.
[0051] It should be further explained that the shell 1 is assembled from an upper shell and a lower shell, the suction nozzle 11 is arranged on the upper shell, the oil cup 3 is also arranged on the upper shell, the fixing groove 12 is arranged on the lower shell, and the battery 8 is detachably installed in the lower shell.
[0052] In order to achieve stable power supply of the battery 8 and the heating core assembly 9, in this embodiment, reference Figure 4 The bracket 2 is provided with two electrodes 91 electrically connected to the heating core assembly 9, and the fixing frame 81 is provided with two ejector pins 82 electrically connected to the battery 8. The battery 8 is inserted into the fixing groove 12 following the fixing frame 81, and the ejector pins 82 are in contact with the electrodes 91 for conduction.
[0053] It is understandable that, in such a configuration, the ejector pin 82 is a spring ejector pin 82, and through the floating contact of the spring ejector pin 82, the ejector pin 82 can stably contact and conduct with the electrode 91, and at the same time, it is also convenient to disassemble and assemble the battery 8, thereby improving the user experience.
[0054] The electronic cigarette with a replaceable oil storage tank in the embodiment of the present application has an oil cup 3 and a heating core assembly 9 inside the electronic cigarette, and the battery 8 and the oil bottle 5 are both detachable. The battery 8 can be charged through the charging interface 84, and the battery 8 supplies power to the heating core assembly 9 through the ejector pin 82. After the smoke oil in the oil cup 3 flows to the heating core assembly 9 for heating and atomization, the smoke is sucked out by the user from the suction nozzle 11. In normal use, the suction nozzle 11 is upward. When the smoke oil in the oil cup 3 is exhausted, the electronic cigarette is turned over so that the oil filling tube 51 of the oil bottle 5 is facing downward, and the oil filling cap 6 is pulled downward to make it The valve needle 61 is separated from the oil filling pipe 51, and the oil bottle 5 is squeezed, so that the tobacco oil in the oil bottle 5 is injected into the oil cup 3 from the oil filling pipe 51, and the gas in the oil cup 3 is discharged through the pressure relief pipe 63. After filling the tobacco oil, the oil filling cap 6 is pressed in the opposite direction to lock it, and the electronic cigarette can be used normally; after the oil bottle 5 is empty, the empty oil bottle 5 can be removed by rotating it, and a new oil bottle 5 can be replaced to replenish the tobacco oil, so that the electronic cigarette only needs to replace the oil bottle 5 for tobacco oil filling to be continuously used, and the suction nozzle 11, the heating core component 9, etc. can be reused and continuously used, which reduces the waste of resources and is beneficial to environmental protection.
[0055] The above does not limit the technical scope of the present invention. Any modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
