Description

Technical Field

[0001] This utility model relates to the field of electronic cigarette technology, and in particular to an electronic cigarette that can be refilled with e-liquid. Background Technology

[0002] In the field of e-cigarette technology, refilling is a crucial step in the maintenance and use of e-cigarettes. Traditional refilling methods often require users to directly open the e-liquid tank cap and manually drip e-liquid in using a dropper or other tools. This method is not only cumbersome but also prone to e-liquid splattering or contamination during refilling, affecting user experience and e-cigarette performance.

[0003] Current e-cigarette refill designs mostly rely on simple e-liquid storage structures, lacking efficient automatic refill mechanisms. When users find that the e-liquid is low, they need to stop smoking, find suitable e-liquid, and follow the e-cigarette's instructions. This refilling method not only interrupts the user's smoking experience but may also lead to decreased e-cigarette performance or damage due to improper operation.

[0004] Furthermore, while some e-cigarettes feature removable e-liquid tanks, leakage of residual e-liquid after removal can negatively impact the user experience. Additionally, poor sealing at the removable tank can lead to e-liquid evaporation or impurities entering the device, affecting the flavor and lifespan of the e-cigarette. Therefore, this paper proposes an e-cigarette with refillable e-liquid to address these technical issues. Utility Model Content

[0005] The purpose of this invention is to provide an electronic cigarette that can replenish e-liquid in order to address the shortcomings of the existing technology, thereby solving the technical problem that residual e-liquid in the electronic cigarette will leak out from the disassembly point after the e-liquid tank is disassembled.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows:

[0007] An electronic cigarette capable of refilling e-liquid includes a shell and a support frame installed inside the shell. A top shell is installed on the top of the shell; a base is installed at the bottom of the top shell, and a mounting seat is installed on the base inside the top shell. The mounting seat and the inner side wall of the top shell form an atomizing chamber; the mounting seat is formed with a guide chamber located next to the atomizing chamber, and a movable tube that can move up and down is provided in the guide chamber. A support plate is formed inside the movable tube, and a through hole is provided on the support plate to connect the movable tube with the atomizing chamber; a valve component is installed on the support plate to block the through hole to prevent e-liquid in the atomizing chamber from flowing out of the through hole. When the movable tube moves to the top of the guide chamber, the valve component opens the through hole; when the movable tube moves to the bottom of the guide chamber, the valve component blocks the through hole.

[0008] The base is formed with a mounting hole that communicates with and is coaxially arranged with the guide chamber. An oil storage bottle for storing e-liquid is installed at the mounting hole to push the movable tube upward to the top of the guide chamber.

[0009] Furthermore, the atomizing chamber is equipped with an atomizing device for atomizing e-liquid, and the top shell has a mouthpiece that is connected to the atomizing device.

[0010] Furthermore, the base is provided with an upwardly extending connector, which is inserted into the mounting base. The side of the connector that contacts the mounting base has an annular protrusion, which allows the side of the connector to be interference-fitted with the mounting base.

[0011] Furthermore, the valve component includes a guide cylinder mounted on a support plate, and a slide rod that slides up and down inside the guide cylinder. The bottom end of the slide rod is provided with a plugging element located directly below the through hole and used to block the through hole. The top end of the slide rod is provided with a fixing element, and a spring is wound around the slide rod and placed inside the guide cylinder to apply a downward pushing force to the movable tube.

[0012] Furthermore, the top of the oil storage bottle is provided with a bottle tube for pushing the movable tube upward and communicating with it, and the outer wall of the bottle tube is threadedly connected to the inner wall of the mounting hole.

[0013] Furthermore, a sealing sleeve is installed at the bottom of the active tube to prevent e-liquid leakage when connected to the bottle tube.

[0014] Furthermore, the top of the active tube is provided with an oil outlet for guiding the e-liquid, and the mounting base is formed with an oil guiding channel between the oil outlet and the atomizing chamber.

[0015] Furthermore, an air inlet is provided on the side of the top shell and is connected to the atomizing chamber. The support frame is provided with a slider for controlling the amount of airflow entering the atomizing chamber from the air inlet. Several ventilation holes are formed on the slider and arranged in a vertical row to connect the air inlet with the outside air. A contact block is installed on the slider that passes through the outer shell.

[0016] The beneficial effects of this utility model are as follows: During the process of installing the oil storage bottle at the mounting hole, the movable tube will be pushed upward. After the oil storage bottle is installed, the movable tube is pushed to the top of the guide chamber. At the same time, the movable tube is connected to the oil storage bottle, and the valve component automatically opens the through hole, so that the movable tube is connected to the atomizing chamber. By tilting this electronic cigarette, the e-liquid in the oil storage bottle flows into the movable tube, and then flows into the atomizing chamber through the through hole, thereby achieving the replenishment of e-liquid.

[0017] After the oil reservoir is removed from the mounting hole, the movable tube automatically moves to the bottom of the guide chamber, causing the valve component to block the through hole to prevent the e-liquid in the atomizing chamber from flowing out and causing e-liquid leakage. By installing and removing the oil reservoir, and in cooperation with the valve component, the through hole is automatically opened or blocked, preventing e-liquid leakage, as well as preventing e-liquid evaporation or impurities from entering, thus improving the user experience and service life.

[0026] The following is a detailed description of an electronic cigarette with e-liquid replenishment according to the present invention, with reference to the accompanying drawings.

[0027] like Figure 1-6As shown, an embodiment of the present invention, an electronic cigarette capable of e-liquid refilling, includes a housing 1 and a support frame 3 installed inside the housing 1. A bottom shell 2 is snap-fitted to the bottom of the housing 1, and a top shell 4 is snap-fitted to its top. A base 5 is installed at the bottom of the top shell 4, and a mounting seat 6 is installed on the base 5, placed inside the top shell 4. To mount the mounting seat 6 onto the base 5, the base 5 has an upwardly extending connector 7, which is inserted into the mounting seat 6. An annular protrusion 71 is provided on the side of the connector 7 that contacts the mounting seat 6. Under the action of the protrusion 71, the side of the connector 7 is press-fitted into the mounting seat 6, and the mounting seat 6 is mounted onto the base 5 by insertion, facilitating the installation and removal of the electronic cigarette.

[0028] Furthermore, the mounting base 6 and the inner wall of the top shell 4 form an atomizing chamber 61, and an atomizing device 8 (model ASK-106W) for atomizing e-liquid is installed inside the atomizing chamber 61. The atomizing chamber 61 can store 2ml of e-liquid, and the e-liquid inside the atomizing chamber 61 can be atomized by operating the atomizing device 8. A mouthpiece 41 is formed on the top of the top shell 4 and is connected to the atomizing device 8. When the user smokes through the mouthpiece 41, the atomizing device 8 is operated, and the generated smoke is inhaled by the user through the mouthpiece 41. The atomizing device 8 is prior art and will not be described in detail here.

[0029] To facilitate the replenishment of e-liquid into the atomizing chamber 61, the mounting base 6 is formed with a guide chamber 9 located next to the atomizing chamber 61. The guide chamber 9 is provided with a movable tube 10 that can move up and down. After applying force to the movable tube 10, it can move up and down within the guide chamber 9. A support plate 101 is formed inside the movable tube 10, and the support plate 101 has a through hole 102 that connects the movable tube 10 to the atomizing chamber 61. The movable tube 10 guides the e-liquid, which then flows into the atomizing chamber 61 through the through hole 102. The support plate 101 is also equipped with a valve component to block the through hole 102 to prevent the e-liquid in the atomizing chamber 61 from flowing out of the through hole 102. When the movable tube 10 moves to the top of the guide chamber 9, the valve component opens the through hole 102, allowing the e-liquid to flow through the movable tube 10 and then into the atomizing chamber 61 through the through hole 102, thus replenishing the e-liquid. When the movable tube 10 moves to the bottom of the guide chamber 9, the valve component blocks the through hole 102 (e.g., when the movable tube 10 moves to the bottom of the guide chamber 9). Figure 6 (As shown), to prevent e-liquid in the atomizing chamber 61 from flowing out of the through hole 102 and causing e-liquid leakage.

[0030] Furthermore, the base 5 is formed with a mounting hole 51 that communicates with and is coaxially arranged with the guide chamber 9. The mounting hole 51 is located directly below the guide chamber 9. The oil reservoir 15 for storing e-liquid is detachably installed at the mounting hole 51 to push the movable tube 10 upward to the top of the guide chamber 9. During the process of installing the oil reservoir 15 at the mounting hole 51, the movable tube 10 will be pushed upward. After the oil reservoir 15 is installed, the movable tube 10 is pushed to the top of the guide chamber 9. At the same time, the movable tube 10 is connected to the oil reservoir 15, and the valve component opens the through hole 102, so that the movable tube 10 is connected to the atomizing chamber 61. By tilting the electronic cigarette, the e-liquid in the oil reservoir 15 flows into the movable tube 10, and then flows into the atomizing chamber 61 through the through hole 102, thereby achieving the replenishment of e-liquid.

[0031] Specifically, the top of the oil storage bottle 15 is provided with a bottle tube 16 for pushing the movable tube 10 upward and communicating with it, and the outer wall of the bottle tube 16 is threadedly connected to the inner wall of the mounting hole 51. When the oil storage bottle 15 needs to be installed, the bottle tube 16 is aligned with the mounting hole 51 and rotated to screw the bottle tube 16 into the mounting hole 51. During the rotation, the bottle tube 16 continues to move upward, thereby pushing the movable tube 10 upward. When the bottle tube 16 is tightened, the movable tube 10 is exactly at the apex of the guide chamber 9, and the valve component opens the through hole 102. Conversely, when the oil storage bottle 15 needs to be disassembled, the oil storage bottle 15 is rotated in the opposite direction to unscrew the bottle tube 16 from the mounting hole 51. At the same time, the movable tube 10 returns to the bottom point of the guide chamber 9, and the valve component re-blocks the through hole 102.

[0032] A sealing sleeve 17 is installed at the bottom of the movable tube 10 to prevent e-liquid leakage when it is connected to the bottle tube 16. When the bottle tube 16 is connected to the movable tube 10, the sealing sleeve 17 is placed between the bottle tube 16 and the movable tube 10 to prevent e-liquid from leaking out from the gap between them.

[0033] Furthermore, the valve component includes a guide cylinder 103 disposed on the support plate 101, and a slide rod 11 is provided slidably inside the guide cylinder 103. The bottom end of the slide rod 11 is provided with a plugging member 14 located directly below the through hole 102 and used to block the through hole 102. The top end of the slide rod is provided with a fixing member 12. A spring 13 is placed inside the guide cylinder 103 and is wound around the slide rod 11 to apply a downward pushing force to the movable tube 10. The fixing member 12 contacts or is fixed to the top of the inner shell 4. When installing the oil reservoir 15, the movable tube 10 is pushed upward, and the movable tube 10 slides upward along with the guide tube 103. The spring 13 is compressed, and the blocking member 14 disengages from the through hole 102, so that the through hole 102 is connected to the movable tube 10, thereby opening the through hole 102. Conversely, when disassembling the oil reservoir 15, the movable tube 10 is pushed downward under the action of the compression spring 13, so that the blocking member 14 re-blocks the through hole 102. While replacing the oil reservoir 15, the leakage of e-liquid produced in the e-cigarette from the movable tube 10 is prevented, improving the user experience. In addition, it can also prevent e-liquid evaporation or impurities from entering, improving the taste and service life of the e-cigarette.

[0034] Additionally, an outlet 104 for guiding e-liquid flow is provided at the top of the movable tube 10, and an oil guiding channel 18 is formed on the mounting base 6 between the outlet 104 and the atomizing chamber 61. After the e-liquid flows into the movable tube 10, it flows through the through hole 102, and then the outlet 104 and the oil guiding channel 18 cooperate to guide the e-liquid into the atomizing chamber 61, thereby achieving rapid e-liquid replenishment and improving replenishment efficiency.

[0035] The top shell 4 has an air inlet 19 connected to the atomizing chamber 61 on its side. The support frame 3 has a slider 20 that slides up and down to control the airflow rate into the atomizing chamber 61 from the air inlet 19. The slider 20 has several vertically arranged vents 21 that connect the air inlet 19 to the outside air. When the airflow rate into the air inlet 19 is at its maximum, all the vents 21 are connected to the air inlet 19. When force is applied to the slider 20 to make it move upward, the number of vents 21 connected to the air inlet 19 gradually decreases. When only one vent 21 is connected to the air inlet 19, the airflow rate into the air inlet 19 is at its minimum. Furthermore, when the slider 20 moves upward to its maximum position, the slider 20 blocks the air inlet 19 to prevent e-liquid leakage when the electronic cigarette is not in use. To facilitate the user's application of force to the slider 20, a contact block 22 passing through the outer casing 1 is installed on the slider 20. After the user touches the contact block 22 with their finger, they apply force to control the slider 20 to slide up and down. The base 5 is equipped with a microphone (not shown in the figure) for detecting airflow. The microphone is an airflow sensor. When the microphone detects air entering the atomizing device 8, it controls the operation of the atomizing device 8.

[0036] A circuit board 23 and a display panel 25 are installed inside the support frame 3. A battery 24 electrically connected to the circuit board 23 is also installed. A control button 26 for controlling the operation of the electronic cigarette is located on the outside of the outer casing 1. When the user needs to use it, pressing the control button 26 will activate the electronic cigarette. The display panel 25 displays the capacity of the e-liquid in the reservoir 15 and the remaining power of the battery 24. The circuit board 23, battery 24, display panel 25, and control button 26 are all existing technologies and will not be described in detail here.

[0037] In summary, this utility model possesses the aforementioned excellent characteristics, enabling it to achieve unprecedented efficiency in use and thus become a highly practical product.

[0038] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
