Description

Technical Field

[0001] This utility model relates to the field of electronic cigarette technology, and more specifically, to a novel two-in-one e-cigarette cartridge. Background Technology

[0002] The e-liquid cartridge with external oil bottle mainly consists of two parts: the cartridge and the oil bottle. The oil bottle is used to store e-liquid. The cartridge has at least an e-liquid storage component and an atomizing component for atomizing the e-liquid. There is also a flow channel between the oil bottle and the cartridge to guide the e-liquid in the oil bottle to the atomizing component. When powered on, the atomizing component generates high temperature to atomize the e-liquid, thereby forming vapor.

[0003] According to the laws and regulations of some foreign countries or regions, the e-liquid content of a single e-cigarette cartridge should be less than or equal to 2 ml. Some e-cigarette users feel that the e-liquid content is too low, requiring frequent cartridge replacements or refills, which affects the user experience. To improve the user experience, some e-cigarette manufacturers add an extra e-liquid bottle outside the cartridge or reservoir to increase the e-liquid volume. However, current external refill bottles have poor sealing properties, and the connection between the external refill bottle and the cartridge is not tight, thus posing a risk of e-liquid leakage.

[0004] The above shortcomings need to be improved. Utility Model Content

[0005] In order to overcome the shortcomings of existing technologies, this utility model provides a novel two-in-one e-cigarette cartridge with good sealing performance, which can greatly prevent e-liquid leakage.

[0006] The novel two-in-one e-cigarette cartridge provided by this utility model includes an e-cigarette cartridge body and an oil bottle that is detachably connected to the e-cigarette cartridge body; the oil bottle includes an oil storage cavity, a sealing cavity for sealing the e-cigarette cartridge body, and a sealing component for sealing the oil storage cavity. The e-cigarette cartridge body is slidably disposed in the sealing cavity and cooperates with the sealing component to form a sealed communication with the oil storage cavity.

[0007] Compared with existing technologies, the novel two-in-one e-liquid cartridge provided by this utility model seals the e-liquid storage chamber by setting a sealing component inside the e-liquid bottle, and also sets a sealing cavity inside the e-liquid bottle, with the cartridge body slidably placed in the sealing cavity. This allows the cartridge body and the e-liquid bottle to be detachably and sealed together. Furthermore, the cartridge body can cooperate with the sealing component to ensure a sealed connection between the cartridge body and the e-liquid storage chamber, thereby increasing the e-liquid volume while greatly preventing leakage due to poor sealing. In addition, this detachable structure of the cartridge body and the e-liquid bottle improves the overall integrity of the device, allowing for plug-and-play use and facilitating the addition of an e-liquid bottle while further enhancing user comfort.

[0008] Specifically, the sealing assembly includes a first sealing element and a second sealing element; the first sealing element is disposed at the open end of the oil storage cavity and is used to seal the inner wall of the oil storage cavity; the first sealing element is also provided with a through oil outlet hole, and the second sealing element is disposed at the end of the first sealing element away from the oil storage cavity and is used to seal the oil outlet hole; the second sealing element and the first sealing element are detachably sealed together.

[0009] Specifically, the sealing assembly also includes a third seal, which is disposed between the first seal and the second seal and is used to cooperate with the first and second seals to form a sealed oil delivery channel between the oil storage chamber and the sealing chamber when the first seal and the second seal are separated.

[0010] Specifically, the second seal has a sealing plug rod at one end facing the first seal. The sealing plug rod can penetrate the third seal and block the oil outlet hole, so that the second seal is sealed to both the first seal and the third seal.

[0011] Specifically, the end of the cartridge facing the oil bottle is provided with an oil inlet and a drive protrusion. The drive protrusion is used to drive the second seal to separate from the first seal to form an oil delivery channel and to connect the oil inlet with the oil delivery channel.

[0012] Specifically, both the first and third seals are annular, and both the outer circumferential surface and the inner ring sidewall of the first and third seals are provided with sealing protrusions for auxiliary sealing.

[0013] Specifically, the oil bottle also includes a shell and a sealing cap located at the bottom of the shell. The oil storage cavity, the sealing cavity, the first sealing element, the second sealing element and the third sealing element are all located inside the shell, and the sealing cap and the third sealing element abut against each other to support the third sealing element.

The sealing cap 24 is also provided with a positioning protrusion 241, and the shell 20 is provided with a positioning hole 201 that cooperates with the positioning protrusion 241 to position the sealing cap 24. The cartridge body 1 is slidably disposed in the sealing cavity 22 and cooperates with the sealing component 23 to form a sealed communication with the oil storage cavity 21.

[0027] Further, please refer to Figure 2 and Figure 4 The cartridge body 1 includes a cartridge shell 10, a mouthpiece 11, upper absorbent cotton 12, an e-liquid tank 13, e-liquid storage cotton 14, a heating wire assembly 15, a cartridge sealing silicone 16, a lower absorbent cotton 17, a cartridge bottom cover 18, and a flue 19. The mouthpiece 11 is located at the top of the cartridge shell 10 and communicates with the flue 19. The heating wire assembly 15 communicates with the e-liquid tank 13. The e-liquid storage cotton 14 is located within the e-liquid tank 13 and stores and delivers e-liquid to the heating wire assembly 15 for atomization. The upper absorbent cotton 12 is located between the mouthpiece 11 and the flue 19. The lower absorbent cotton 17 is located between the cartridge bottom cover 18 and the e-liquid tank 13. The cartridge sealing silicone 16 is located between the lower absorbent cotton 17 and the e-liquid tank 13 for sealing. The cartridge bottom cover 18 is located at the bottom of the cartridge shell 10, and the cartridge bottom cover 18 and the cartridge shell 10 are sealed together. More specifically, in order to ensure a tight seal between the cartridge body 1 and the oil bottle 2, the cartridge shell 10 and the sealing cavity 22 are in a transition fit.

[0028] Further, please refer to Figures 2 to 4 as well as Figure 6The sealing assembly 23 includes a first sealing element 231, a second sealing element 232, and a third sealing assembly 233. The first sealing element 231 is disposed at the open end of the oil storage chamber 21 and is used to seal the inner wall of the oil storage chamber 21. The first sealing element 231 also has a through oil outlet 234. The second sealing element 232 is disposed at the end of the first sealing element 231 away from the oil storage chamber 21 and is used to seal the oil outlet 234. The second sealing element 232 and the first sealing element 231 are detachably and sealingly connected. The third sealing element 233 is disposed between the first sealing element 231 and the second sealing element 232, and is used to cooperate with the first two elements to form a sealed oil delivery channel 236 between the oil storage chamber 21 and the sealing chamber 22 when the first sealing element 231 and the second sealing element 232 are separated. The second sealing element 232 is further provided with a sealing plug rod 235 at one end facing the first sealing element 231. The sealing plug rod 235 can penetrate the third sealing element 233 and block the oil outlet hole 234, so that the second sealing element 232 is sealed to both the first sealing element 231 and the third sealing element 233. Correspondingly, the third sealing element 233 is provided with a sealing hole 237 for the sealing plug rod 235 to pass through. In this embodiment, both the first sealing element 231 and the third sealing element 233 are annular, and the outer peripheral surface and inner ring sidewall of the first sealing element 231 and the third sealing element 233 are provided with sealing protrusions 238 for auxiliary sealing. There are two oil outlet holes 234, and the two oil outlet holes 234 are arranged opposite each other on the first sealing element 231. Similarly, there are also two sealing holes 237 and two sealing plug rods 235, which are arranged opposite each other. Furthermore, both the oil outlet hole 234 and the sealing hole 237 have sealing protrusions 238 on their inner walls for auxiliary sealing.

[0029] Further, please refer to Figure 1 and Figure 6 The end of the cartridge body 1 facing the oil bottle 2 is also provided with an oil inlet 101 and a driving protrusion 102. The driving protrusion 102 is used to drive the second seal 232 to separate from the first seal 231 to form an oil delivery channel 236, and to connect the oil inlet 101 with the oil delivery channel 236. In this embodiment, the oil inlet 101 is provided on the cartridge shell 10 and there are two of them. The driving protrusion 102 is provided on the outer surface between the two ends of the cartridge bottom cover 18, thereby forming a driving step with the outer surface of the cartridge bottom cover 18.

[0030] Further, please refer to Figure 4The first seal 231 and the third seal 233 have multiple sealing protrusions 238 arranged axially. This arrangement reduces the eccentricity of the first seal 231 and the third seal 233 due to thermal expansion, and the presence of multiple sealing protrusions 238 allows for a small degree of deflection of the sealing surface, preventing e-liquid leakage due to misalignment between the first seal 231 and the third seal 233. In this embodiment, both the first seal 231 and the third seal 233 are silicone sealing rings, and the sealing protrusions 238 are also made of silicone. Therefore, when the cartridge body 1 is inserted into the sealing cavity 21, the outer wall of the cartridge shell 10 will press against the sealing protrusions 238 on the inner ring sidewalls of both the first seal 231 and the third seal 233, thereby further enhancing the sealing performance and the reliability of the connection. Similarly, when the sealing plug rod 235 passes through the first seal 231 and the third seal 233, the outer wall of the sealing plug rod 235 will also press against the sealing protrusions 238 on the inner walls of the oil hole 234 and the sealing hole 237 to enhance the sealing performance.

[0031] The following is a description of the working principle of the novel two-in-one e-cigarette cartridge 100 provided by this utility model. Since the cartridge body 1 and the oil bottle 2 are detachably connected, the cartridge body 1 needs to be inserted into the sealing cavity 22 of the oil bottle 2 before use. During the insertion of the cartridge body 1, the driving protrusion 102 on the cartridge body 1 gradually pushes the second seal 233, causing the second seal 233 to gradually move away from the oil outlet 234, thereby causing the sealing plug 235 to slowly be pulled out of the oil outlet 234. When the sealing plug 235 is completely pulled out of the oil outlet 234, the oil delivery channel 236 begins to form. However, at this time, the oil inlet 101 on the cartridge body 1 is not yet connected to the oil delivery channel 236. The cartridge body 1 continues to be pushed until the second seal 232 abuts against the sealing cap 24 of the oil bottle 2. At this point, the cartridge body 1 is installed in place, and the oil inlet 101 is also connected to the oil delivery channel. After the cartridge body 1 and the e-liquid bottle 2 are installed, the heating wire assembly 15 is activated. The heating wire assembly heats the e-liquid and eventually atomizes it. The user can then inhale the atomized e-liquid through the mouthpiece 11 on the cartridge body 1.

[0032] Compared with the prior art, the novel two-in-one e-liquid cartridge 100 provided by this utility model seals the oil storage chamber 21 by setting a sealing component 23 inside the oil bottle 2, and also sets a sealing cavity 22 inside the oil bottle 2, and slidably sets the e-liquid cartridge body 1 in the sealing cavity 22, so that the e-liquid cartridge body 1 and the oil bottle 2 are detachably and sealedly connected. The e-liquid cartridge body 1 can also cooperate with the sealing component 23 to make the e-liquid cartridge body 1 and the oil storage chamber 21 sealedly connected, thereby increasing the amount of e-liquid while greatly avoiding e-liquid leakage due to poor sealing. In addition, this detachable structure of the e-liquid cartridge body 1 and the oil bottle 2 makes the overall structure of the e-cigarette better, and it is plug-and-play. It not only facilitates the addition of the oil bottle 2, but also further enhances the user's comfort.

[0033] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
