Description

Technical Field

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

[0002] In the field of e-cigarette technology, traditional e-cigarette designs often face challenges in e-liquid replenishment and management. In particular, when the e-liquid in the e-cigarette's reservoir is depleted, it needs to be replenished externally. However, this process often results in e-liquid backflow, meaning that under certain conditions (such as when the e-cigarette is tilted or inverted), the e-liquid replenished into the reservoir can easily flow back into the reservoir. This backflow not only wastes e-liquid but can also affect the normal operation of the e-cigarette, and may even lead to internal leakage, thus reducing the user experience.

[0003] Specifically, traditional e-cigarette e-liquid storage systems typically connect the e-liquid bottle directly to the e-liquid chamber, lacking an effective mechanism to prevent backflow. Therefore, during e-liquid replenishment or use, if the e-cigarette's orientation changes, the e-liquid in the chamber may flow back into the bottle due to gravity. This backflow not only reduces the amount of e-liquid available for vaporization in the chamber but can also contaminate or damage internal components due to contact with the e-cigarette during the backflow process. Therefore, this paper proposes an e-cigarette that prevents e-liquid backflow to address these technical problems. Utility Model Content

[0004] The purpose of this invention is to provide an electronic cigarette that prevents e-liquid from flowing back into the storage bottle, addressing the shortcomings of existing technologies.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] An electronic cigarette designed to prevent e-liquid backflow includes a casing, inside which are installed a cartridge component for generating e-liquid smoke and a battery component for controlling the operation of the cartridge component. The cartridge component and the battery component are connected together. The cartridge component includes a cartridge shell and a partition frame installed inside the cartridge shell. A base is installed at the bottom of the cartridge shell, and a second sealing block is provided on the base. The second sealing block and the partition frame enclose an e-liquid guiding chamber. A first sealing block is provided at the top of the partition frame, and the first sealing block and the interior of the shell enclose an e-liquid storage chamber. An e-liquid guiding channel is formed on the first sealing block and the partition frame to connect the e-liquid guiding chamber and the e-liquid storage chamber. An e-liquid storage bottle connected to the e-liquid guiding chamber is installed at the bottom of the base. A bone is formed on the top of the first sealing block and placed inside the e-liquid storage chamber. The bone is located at the opening of the e-liquid guiding channel and is used to block e-liquid.

[0007] Furthermore, the oil guide channel is offset from the center position of the oil guide chamber and the oil storage chamber.

[0008] Furthermore, the top of the outer casing is equipped with a removable top cover, and the top cover is formed with a mouthpiece that is connected to the cartridge component.

[0009] Furthermore, the bottom of the top cover is formed with a splicing part that can be embedded into the outer shell. Several protrusions are provided around the splicing part. An L-shaped mounting groove is formed on the inner side wall of the top of the outer shell for the protrusions to be embedded in. Each protrusion is provided with a slot, and a snap-fit ​​protrusion that can be snapped into the slot is formed at the end of the mounting groove.

[0010] Furthermore, a sealing plug is provided at the smoke outlet of the mouthpiece.

[0011] Furthermore, the first sealing block is equipped with an atomizing component located in the oil storage chamber and communicating with the mouthpiece.

[0012] Furthermore, the base has ventilation holes, and the partition frame has an air channel that connects the atomizing component with the ventilation holes. The air channel contains absorbent cotton placed below the atomizing component to prevent e-liquid leakage. The base is equipped with a power-on terminal that is electrically connected to the atomizing component and is used to contact the battery component.

[0013] Furthermore, the atomizing component includes a cylinder and a bottom sealing block installed at the bottom of the cylinder, and a top sealing block installed at the top of the cylinder. The cylinder, the bottom sealing block and the top sealing block enclose an atomizing chamber. An oil storage cotton for storing e-liquid is provided inside the atomizing chamber, and an atomizing device for atomizing e-liquid is provided inside the oil storage cotton. Several through holes are provided on the side of the cylinder to connect the atomizing chamber with the oil storage chamber.

[0014] Furthermore, the oil storage bottle includes an upwardly extending bottle tube, and a mounting position is formed on the base that communicates with the oil guiding chamber, and the mounting position is threadedly connected to the outside of the bottle tube.

[0015] Furthermore, the installation position is equipped with a tube that can be inserted into the bottle tube, and a seal is provided between the tube and the bottle tube to prevent e-liquid leakage.

[0016] The beneficial effects of this invention are as follows: When the e-liquid in the oil storage chamber is used up, the e-cigarette is poured out, and the e-liquid in the oil storage bottle flows into the oil guiding chamber. Then, the e-liquid is guided to the oil storage chamber for storage through the oil guiding channel. After enough e-liquid has flowed into the oil storage chamber, the e-cigarette is straightened again. The e-liquid in the oil storage chamber is blocked by the rib, preventing the e-liquid from flowing back into the oil guiding chamber through the oil guiding channel, thus improving the e-liquid replenishment effect.

[0017] In addition, the oil storage chamber can store 2ml of e-liquid. By setting up an oil guiding chamber and an oil guiding channel, the oil storage chamber is separated from the oil bottle, which prevents the oil from being supplied directly through the oil bottle, resulting in a large supply of oil and the inability to fully vaporize the e-liquid. This avoids the risk of e-liquid leakage and improves the user experience. Attached Figure Description

[0027] The following is a detailed description of an electronic cigarette that prevents e-liquid backflow, in conjunction with the accompanying drawings.

[0028] like Figure 1-2As shown, an embodiment of the electronic cigarette for preventing e-liquid backflow according to this utility model includes a shell 1. Inside the shell 1, there is a cartridge component for generating e-liquid smoke and a battery component for controlling the operation of the cartridge component. The cartridge component and the battery component are connected together. A top cover 27 is installed on the top of the shell 1. The top cover 27 is detachable and has a mouthpiece 29 formed on the top cover 27 that communicates with the cartridge component. When the user smokes through the mouthpiece 29, outside air first enters the battery component and then enters the cartridge component, causing the cartridge component to operate. The air then carries the smoke generated by the cartridge component out for the user to inhale.

[0029] To achieve a detachable connection between the top cover 27 and the top of the outer shell 1, the bottom of the top cover 27 is formed with a splicing part 28 that can be embedded into the outer shell 1. Several protrusions 23 are provided around the splicing part 28. An L-shaped mounting groove 24 is formed on the inner sidewall of the top of the outer shell 1 for the protrusions 23 to be inserted. The splicing part 28 is inserted into the outer shell 1 from top to bottom, and simultaneously, the protrusions 23 are also inserted into the mounting groove 24. Then, the connection is rotated clockwise (the rotation direction is...). Figure 7 (Based on the reference) Rotate the top cover 27 so that the protrusion 23 moves to the end of the mounting groove 24, completing the installation of the top cover 27. In addition, each protrusion 23 is provided with a slot 26, and the end of the mounting groove 24 is formed with a snap-fit ​​protrusion 25 that can be snapped into the slot 26; when the protrusion 23 moves to the end of the mounting groove 24, the snap-fit ​​protrusion 25 snaps into the slot 26, thereby realizing the snap-fit ​​between the top cover 27 and the outer shell 1, so that the top cover 27 is stably installed on the top of the outer shell 1. A sealing plug 30 is provided at the smoke outlet of the mouthpiece 29. When the electronic cigarette is not in use, the sealing plug 30 blocks the smoke outlet of the mouthpiece 29 to prevent e-liquid from leaking out of the mouthpiece 29 or impurities from entering the electronic cigarette, thereby improving the service life of the electronic cigarette.

[0030] like Figure 3-4As shown, the cartridge component includes a cartridge shell 2 and a partition frame 3 installed inside the cartridge shell 2. A base 301 is installed at the bottom of the cartridge shell 2. A second sealing block 6 is provided on the base 301. The second sealing block 6 and the partition frame 3 form an oil guiding chamber 7. A first sealing block 4 is provided at the top of the partition frame 3. The first sealing block 4 and the inside of the shell 2 form an oil storage chamber 5 for storing e-liquid. The oil storage chamber 5 can store 2ml of e-liquid. An oil guiding channel 8 is formed on the first sealing block 4 and the partition frame 3 to connect the oil guiding chamber 7 and the oil storage chamber 5. The oil guiding channel 8 is offset from the center position of the oil guiding chamber 7 and the oil storage chamber 5. An oil storage bottle 14 is installed at the bottom of the base 301 and is connected to the oil guiding chamber 7. After the e-cigarette is poured out, the e-liquid in the reservoir 14 flows into the wicking chamber 7, and then is guided through the wicking channel 8 to the reservoir 5 for storage. After enough e-liquid has flowed into the reservoir 5, the e-cigarette is straightened again. However, in order to prevent the e-liquid in the reservoir 5 from flowing back into the wicking chamber 7 through the wicking channel 8, a rib 9 is formed on the top of the first sealing block 4 and placed in the reservoir 5. The rib 9 is located at the opening of the wicking channel 8 and is used to block the e-liquid to prevent backflow. After the e-cigarette is straightened, the e-liquid in the reservoir 5 is blocked by the rib 9, so that the e-liquid cannot flow back into the wicking chamber 7 through the wicking channel 8.

[0031] In addition, an atomizing component 10 is installed on the first sealing block 4, which is located in the oil storage chamber 5 and communicates with the mouthpiece 29. The e-liquid in the oil storage chamber 5 enters the atomizing component 10. When the user smokes through the mouthpiece 29, the atomizing component 10 operates to heat and atomize the e-liquid for the user to inhale. After the e-liquid in the atomizing component 10 is completely atomized, the e-liquid in the oil storage chamber 5 automatically flows into the atomizing component 10, so that the e-liquid in the atomizing component 10 is always sufficient, realizing automatic replenishment of e-liquid. Furthermore, when the e-liquid in the oil storage chamber 5 is used up, the e-liquid in the oil bottle 14 can be replenished into the oil storage chamber 5 by emptying the electronic cigarette.

[0032] Furthermore, the base 301 has ventilation holes 12 formed on it, and the partition frame 3 has an air guiding channel 11 formed on it, which connects the atomizing component 10 with the ventilation holes 12. When the user smokes through the mouthpiece 29, air enters through the ventilation holes 12 and is guided through the air guiding channel 11, so that the air flows from bottom to top through the interior of the atomizing component 10. An oil-absorbing cotton 31 is placed below the atomizing component 10 in the air guiding channel 11 to prevent e-liquid leakage. E-liquid that is not fully atomized in the atomizing component 10 flows into the air guiding channel 11 and is absorbed by the oil-absorbing cotton 31, preventing leakage from the ventilation holes 12. Additionally, the base 301 is also equipped with a power-on terminal 13 that is electrically connected to the atomizing component 10 and is used to contact the battery component. After the cartridge component and the battery component are connected, the power-on terminal 13 contacts the battery component, realizing the power supply and control of the atomizing component 10.

[0033] To enable the oil reservoir 14 to be installed at the bottom of the base 301, the oil reservoir 14 includes an upwardly extending bottle tube 141. The base 301 has a mounting position 15 formed on it, which communicates with the oil guiding chamber 7, and the mounting position 15 is threaded to the outside of the bottle tube 141. By rotating the oil reservoir 14, the bottle tube 141 is screwed into the mounting position 15, so that the oil reservoir 14 is installed on the base 301 and communicates with the oil guiding chamber 7. Furthermore, when the e-liquid in the oil reservoir 14 is used up, the oil reservoir 14 can be unscrewed from the base 301 and then refilled. An insert tube 16 is provided in the mounting position 15, which can be inserted into the bottle tube 141. A seal 142 for preventing e-liquid leakage is provided between the insert tube 16 and the bottle tube 141. The seal 142 is made of silicone. When the bottle tube 141 is screwed into the mounting position 15, the insert tube 16 is inserted into the bottle tube 141. At the same time, the seal 142 fills the gap between the insert tube 16 and the inner wall of the bottle tube 141, preventing e-liquid leakage when using this electronic cigarette and improving the user experience.

[0034] like Figure 5 As shown, the atomizing assembly 10 includes a cylinder 101 and a bottom sealing block 102 installed at the bottom of the cylinder 101, and a top sealing block 104 installed at the top of the cylinder 101. The cylinder 101, bottom sealing block 102, and top sealing block 104 enclose an atomizing chamber. An oil-retaining cotton 103 for storing e-liquid is provided inside the atomizing cotton 103, and an atomizing device 105 for atomizing the e-liquid is installed inside the oil-retaining cotton 103. Several through holes 106 are provided on the side of the cylinder 101 to connect the atomizing chamber and the oil-retaining chamber 5. The e-liquid in the oil-retaining chamber 5 enters the atomizing chamber through the through holes 106 for the oil-retaining cotton 103 to absorb, achieving continuous oil supply. When the user smokes through the mouthpiece 29, air enters the atomizing device 105, and simultaneously, the atomizing device 105 operates, heating and atomizing the e-liquid. Finally, the air carries the smoke out for the user to inhale. The atomizing device 105 is prior art and will not be described in detail here.

[0035] like Figure 6As shown, the battery cell component includes a mounting frame 17 and a circuit board 18 installed within the mounting frame 17. A battery 19 electrically connected to the circuit board 18 is also installed within the mounting frame 17. The circuit board 18 has a USB charging port 20 for charging the battery 19. By connecting a charging cable to the USB charging port 20, the battery 19 can be charged. A spring electrode 21 is provided at the top of the mounting frame 17 for contacting the power supply terminal 13, through which power can be supplied to the atomizing device 105. The top of the mounting bracket 17 has an air inlet 22 that communicates with the outside air, and the air inlet 22 is connected to the vent 12. An air inlet 22 contains a microphone (not shown in the figure) for detecting airflow. The microphone is an airflow sensor. When the user smokes, outside air enters the electronic cigarette through the air inlet 22, then enters the air passage 11 through the vent 12, guiding the air into the atomizing device 105. Once the incoming air is detected by the microphone, it controls the atomizing device 105, causing the air to carry the smoke out. The microphone, circuit board 18, battery 19, USB charging terminal 20, and spring electrode 21 are all existing technologies and will not be described in detail here.

[0036] 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.

[0037] 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.
