Description

Technical Field

[0001] This utility model belongs to the field of electronic cigarette technology, and in particular relates to a novel electronic cigarette. Background Technology

[0002] Electronic cigarettes are a new type of smoking device. They use an atomizing core to heat e-liquid, which is then atomized into smoke particles, which are then inhaled into the lungs. Compared to traditional smoking devices, e-liquid components can be customized, the flavor of the smoke can be adjusted, and the heating and atomization process can be controlled, giving electronic cigarettes a high degree of controllability.

[0003] As attached Figure 1 As shown, existing electronic cigarettes mainly include a main shell and an oil reservoir, an atomizing core, and a power supply unit installed inside the main shell. The atomizing core consists of an atomizing tube connected to the mouthpiece of the main shell, an oil-guiding cotton built into the atomizing tube, and a heating element embedded in the oil-guiding cotton. The oil reservoir is used to supply oil to the oil-guiding cotton, and the power supply unit is used to supply power to the heating element, so that the atomizing core can heat the e-liquid. The resulting vapor enters the atomizing tube for the user to inhale, making it relatively convenient to use.

[0004] However, in practical use, it has been found that because the oil-collecting cotton in this electronic cigarette is molded as a single piece and needs to cover the atomizer core, not only is the assembly more troublesome, but the oil-guiding cotton also has difficulty in quickly guiding the e-liquid in the oil-collecting cotton to the heating element, resulting in insufficient oil supply. This makes the oil-guiding cotton prone to carbonization and leads to a decrease in the amount of vapor produced, thereby affecting the lifespan of the atomizer core and the overall inhalation experience.

[0005] Therefore, it is necessary to design a new type of electronic cigarette to solve this problem. Utility Model Content

[0039] See appendix Figure 2 -Appendix Figure 5 and attached Figure 9 A novel electronic cigarette includes a cartridge 1 and a power supply unit 2 mounted on the cartridge 1. The cartridge 1 includes a main shell 11, an atomizing core 12, and an oil storage unit 13. The main shell 11 has an oil storage chamber 110 inside, and an air inlet 111 and a mouthpiece 112 are provided on the main shell 11. The atomizing core 12 includes an atomizing tube 121, an oil-guiding cotton 122, and a heating element 123. The atomizing tube 121 is installed in the oil storage chamber 110 and connects to the air inlet 111 and the mouthpiece 112. The oil-guiding cotton 122 is installed in the atomizing tube 121, a wicking cotton 122, and a heating element 123. The atomizing tube 121 has an oil-absorbing block 1220 protruding into the oil storage tank 110. The heating element 123 is disposed in the atomizing tube 121 and contacts the oil-guiding cotton 122. The power supply unit 2 is electrically connected to the heating element 123. The oil storage component 13 is installed in the oil storage tank 110 and includes a first oil-absorbing cotton 131 and a second oil-absorbing cotton 132 for storing e-liquid. The first oil-absorbing cotton 131 and the second oil-absorbing cotton 132 can surround each other to cover the atomizing core 12 and closely contact the oil-absorbing block 1220.

[0040] Specifically, during assembly, the first oil-retaining cotton 131 and the second oil-retaining cotton 132 are wrapped around each other to cover the atomizing core 12, and the oil-absorbing block 1220 is sandwiched between the first oil-retaining cotton 131 and the second oil-retaining cotton 132. Then, the atomizing core 12, together with the first oil-retaining cotton 131 and the second oil-retaining cotton 132, is installed into the oil storage chamber 110, and e-liquid is injected into the first oil-retaining cotton 131 and the second oil-retaining cotton 132.

[0041] In use, the power supply unit 2 supplies power to the heating element 123, which heats and atomizes the e-liquid on the oil-guiding cotton 122 to form smoke. The smoke enters the atomizing tube 121. Since the air inlet 111, the atomizing tube 121 and the mouthpiece 112 form an airflow channel, the user can inhale the smoke by holding the mouthpiece 112 in their mouth. During inhalation, the oil-absorbing block 1220 continuously absorbs the e-liquid stored in the first oil-retaining cotton 131 and the second oil-retaining cotton 132 and quickly transfers the e-liquid to the oil-guiding cotton 122 for diffusion.

[0042] In summary, this invention improves the assembly convenience of the cartridge 1 by designing the first oil-retaining cotton 131 and the second oil-retaining cotton 132 as separate units. The oil-absorbing block 1220, which protrudes from the atomizing tube 121 and contacts the first and second oil-retaining cotton 131 and 132, is used to absorb and guide e-liquid, increasing the speed at which the oil-guiding cotton 122 guides the e-liquid and ensuring sufficient supply. This effectively prevents the oil-guiding cotton 122 from dry-burning and carbonizing, thus extending the lifespan of the atomizing core 12 and improving the overall vaping experience. Furthermore, the design of the oil-absorbing block 1220 provides a larger e-liquid buffer zone for the oil-guiding cotton 122. When the heating element 123 is not working, this design prevents excessive e-liquid from penetrating the oil-guiding cotton 122 into the atomizing tube 121, reducing the risk of leakage.

[0043] It should be noted that the atomizing tube 121 and heating element 123 of the atomizing core 12 are both existing products. The atomizing tube 121 can be a single support tube, or it can be composed of a steel tube 1211 and a fiberglass tube 1212 (as shown in the attached diagram). Figure 9 As shown), the heating element 123 can be a heating wire embedded in the oil-guiding cotton 122, or a heating rod coaxially inserted into the oil-guiding cotton 122; since the types of atomizing tube 121 and heating element 123 are diverse and relatively common in the field of electronic cigarettes, this utility model does not impose any restrictions on them.

[0044] See appendix Figure 4 -Appendix Figure 7After the user finishes inhaling, some smoke will remain in the mouthpiece 112. This smoke will condense and reform into liquid e-liquid. To prevent this e-liquid from dripping into the atomizing tube 121 and causing contamination of the heating element 123 and the oil-guiding cotton 122, thus affecting the next inhalation experience, this invention provides a return port 1100 on the side wall of the oil storage tank 110, located below the mouthpiece 112. The atomizing tube 121 passes through the return port 1100 into the mouthpiece 112, and atomizes... There is a gap 1120 between the tube 121 and the mouthpiece 112, which connects to the return port 1100. The e-liquid condensed in the mouthpiece 112 will re-enter the oil storage tank 110 through the gap 1120 and the return port 1100 under the action of gravity, and will be absorbed by the first oil storage cotton 131 and the second oil storage cotton 132. Therefore, the above structural design can not only prevent e-liquid from dripping into the atomizing tube 121, but also realize the recycling of e-liquid, thus improving the user experience.

[0045] See appendix Figure 4 -Appendix Figure 5 The inner cavity of the mouthpiece 112 gradually narrows away from the atomizing tube 121, and the inner cavity sidewall of the mouthpiece 112 is arc-shaped. This design makes it easier for the smoke to condense and form inside the mouthpiece 112, and allows the formed e-liquid to easily slide along the inner cavity sidewall of the mouthpiece 112 through the gap to the return port 1100.

[0046] See appendix Figure 2 -Appendix Figure 8 The oil storage tank 110 has a base 113 fixed to the main shell 11 at the bottom. The base 113 has a silicone layer 114 extending into the oil storage tank 110 and fitting against the side wall of the oil storage tank 110. The air inlet 111 is opened on the base 113. The bottom end of the atomizing tube 121 is installed on the silicone layer 114 and connected to the air inlet 111. The design of the base 113 facilitates the disassembly and assembly of the oil storage tank 110 and makes the installation of the oil storage tank 110 more stable. The silicone layer 114 can provide the sealing of the inside of the oil storage tank 110 and provide installation space for the atomizing tube 121, thereby improving the installation stability of the atomizing tube 121.

[0047] See appendix Figure 2 -Appendix Figure 8 The oil storage compartment 110 is made of transparent material, and the main shell 11 has a first transparent area 115 corresponding to the oil storage compartment 110. This design allows users to observe the remaining e-liquid stored in the first oil storage cotton 131 and the second oil storage cotton 132 through the first transparent area 115, which makes it convenient for users to replenish e-liquid or directly discard the e-liquid cartridge 1, avoiding dry inhalation and causing user discomfort.

[0048] See appendix Figure 4 -Appendix Figure 10The power supply unit 2 is widely used in the field of electronic cigarettes and belongs to the prior art. In the prior art, the power supply unit 2 can be directly connected to the cartridge unit 1 as an integral part or assembled separately from the cartridge unit 1. This utility model does not impose any restrictions on this. However, considering that the circuit components are generally expensive, if they are discarded along with the cartridge unit 1, it will increase the cost of use. Therefore, in this utility model, the power supply unit 2 includes a sub-shell 21 and an electronic control unit 22. The sub-shell 21 has a housing 210 inside. The top of the housing 210 is provided with a fixing seat 211 for fixing the sub-shell 21. The fixing seat 211 is detachably connected to the base 113, and the fixing seat 211 is provided with an air passage 2111 that is independent of the housing 210 and connected to the outside. The electronic control unit 22 is installed in the housing 210. When the fixing seat 211 is connected to the base 113, the electronic control unit 22 is electrically connected to the heating element 123, and the air inlet 111 is connected to the air passage 2111.

[0049] Specifically, under normal circumstances, the mounting base 211 is connected to the base 113, and the electronic control unit 22 is electrically connected to the heating element 123, so that the electronic control unit 22 can normally supply power to the heating element 123 and control the operation of the heating element 123; while the air passage 2111 is connected to the air inlet 111, so that the air passage 2111, the air inlet 111, the atomizing tube 121 and the mouthpiece 112 form a complete airflow channel, so that the user can inhale the vapor by holding the mouthpiece 112 in their mouth; when the e-liquid on the first oil storage cotton 131 and the second oil storage cotton 132 is consumed, or when the e-liquid flavor needs to be changed, the user can pry the cartridge 1 to drive the base 113 to detach from the mounting base 211, so as to remove the cartridge 1 from the power supply unit 2, and then reconnect the base 113 of the cartridge 1 containing new e-liquid to the mounting base 211 of the power supply unit 2 to complete the replacement of the cartridge 1.

[0050] In summary, the power supply unit 2 adopts a split design, which makes it convenient for users to change the type of e-liquid, or to discard the cartridge unit 1 after the e-liquid is used up and keep the power supply unit 2 for reuse, so as to effectively improve the user experience and reduce the cost of use; while the independently designed air duct 2111 can prevent external liquids from entering the container 210 and causing damage to the circuit unit.

[0051] See appendix Figure 4 -Appendix Figure 5 and attached Figure 10 -Appendix Figure 13 The power supply unit 2 also includes a gas regulating switch 23. The sub-shell 21 has an opening 212 that connects to the outside. The fixed base 211 also has a sliding groove 2112 that connects to the air passage 2111 and corresponds to the opening 212. The gas regulating switch 23 is slidably installed in the sliding groove 2112 and has a push rod 231 that extends to the opening 212. The gas regulating switch 23 has multiple air regulating holes 230 with the same or different diameters.

[0052] Specifically, the push rod 231 can drive the air regulating switch 23 to move along the slide groove 2112, so that the corresponding air regulating hole 230 connects the air passage 2111 and the notch 212, thereby changing the size of the hole area exposed in the notch 212, thus changing the amount of air entering the air passage 2111 and completing the suction resistance adjustment. Under this design, when the power supply unit 2 is connected to the main shell 11 with atomizing cores 12 with different resistance values, the amount of air can be matched and adapted, thereby satisfying the user's needs for mouth inhalation, light lung inhalation and lung inhalation, further improving the user experience.

[0053] See appendix Figure 2 -Appendix Figure 10 A magnetic block 113x is installed on the base 113, and a magnetic block 211x is installed on the fixing seat 211. The magnetic block 211x can be attracted to the magnetic block 113x so that the fixing seat 211 and the base 113 can be detachably connected, thereby facilitating the assembly and disassembly of the cartridge 1 and the power supply 2.

[0054] It should be noted that, in addition to the above-mentioned structure, the base 113 and the fixed seat 211 can also be disassembled and assembled by means of snap-fit ​​connection, Velcro fastening, etc. Since there are various types of disassembly methods, this utility model does not limit them.

[0055] See appendix Figure 4 -Appendix Figure 5 and attached Figure 10 -Appendix Figure 13 The electronic control unit 22 is widely used in the field of electronic cigarettes and belongs to the prior art. Since there are many types, this utility model does not limit its use. For ease of understanding, in this embodiment, the base 113 is equipped with conductive contacts 1130 electrically connected to the heating element 123, and the fixing base 211 is also provided with a storage slot 2113 having airflow holes 2114. The electronic control unit 22 includes a circuit board 221, a battery 222, a microphone 223, and an energized contact pin 224; the energized contact pin 224... 4. Installed on the fixed base 211; the microphone 223 is installed in the storage slot 2113 and connected to the air passage 2111 through the airflow hole 2114; the circuit board 221 and the battery 222 are both installed in the receiving compartment 210, and the circuit board 221 is electrically connected to the battery 222, the microphone 223 and the power-on contact pin 224; when the fixed base 211 is connected to the base 113, the air passage 2111 is connected to the air inlet 111, and the power-on contact pin 224 contacts the conductive contact 1130 to achieve electrical connection.

[0056] Specifically, when a user inhales through the mouthpiece 112, airflow is generated within the airflow channel formed by the notch 212, air adjustment hole 230, air passage 2111, air inlet 111, atomizing tube 121, and mouthpiece 112. The microphone 223 can sense the airflow through the airflow hole 2114 and send a command to the circuit board 221. After receiving the command, the circuit board 221 controls the battery 222 to supply power to the heating element 123, which heats the e-liquid in the heat-conducting cotton, thereby allowing the user to inhale the vapor.

[0057] It should be noted that the technologies of completing the circuit flow through the energized contact pin 224 and conductive contact 1130, and controlling the operation of the heating element 123 through the microphone 223 and circuit board 221, are all existing technologies, and their specific circuit structures will not be described in detail in this utility model.

[0058] Furthermore, a chip with 20-30W power adjustment function (not shown in the figure) can be set on the circuit board 221 to balance the oil intake rate and air intake rate, and better reproduce the flavor and texture of the e-liquid.

[0059] See appendix Figure 11 -Appendix Figure 13 The electronic control unit 22 also includes a charging port 225, which is installed on the outer wall of the sub-shell 21 and electrically connected to the circuit board 221. The charging port 225 can be used to charge the battery 222 with an external charging cable, ensuring that the user does not need to replace the battery 222, thus further improving its practicality.

[0060] See appendix Figure 11 -Appendix Figure 13 The electronic control unit 22 also includes a display screen 226, which is mounted on the mounting base 211 and electrically connected to the circuit board 221. The sub-shell 21 has a second transparent area 213 corresponding to the display screen 226.

[0061] Specifically, the display screen 226 can be used to display the battery power of 222 and the airflow value detected by the microphone 223 when the user inhales, while the second transparent area 213 allows the user to observe the corresponding data, making it convenient for the user to charge the battery 222 in time according to the battery power or adjust the suction resistance according to the airflow value, thus further improving the user experience.

[0062] See appendix Figure 4 -Appendix Figure 8 The atomizing core 12 is provided with two tubes. The atomizing tubes 121 of the two atomizing cores 12 are synchronously connected to the air inlet 111 and the mouthpiece 112. The first oil storage cotton 131 and the second oil storage cotton 132 can surround each other and synchronously cover the two atomizing cores 12 and the oil absorption block 1220 that is in close contact with the two atomizing cores 12. The power supply unit 2 is electrically connected to the heating element 123 of the two atomizing cores 12 so that the two heating elements 123 can operate synchronously or independently.

[0063] Specifically, the design of two atomizing cores 12 allows the mouthpiece 112 to simultaneously connect to two airflow channels. If the power supply unit 2 supplies power to both heating elements 123 at the same time, smoke is generated in both airflow channels, making it convenient for users to inhale a large amount of smoke. If the power supply unit 2 supplies power to only one heating element 123, the amount of smoke generated will be reduced accordingly. Therefore, the above structural design can meet the taste requirements of different users and further improve the user experience. On the other hand, when one atomizing core 12 is damaged, the other atomizing core 12 can still work normally, avoiding waste of e-liquid, effectively extending the service life of the e-cigarette and improving the utilization rate of e-liquid.

[0064] It should be noted that the technology of supplying power to any one atomizing core 12 in the cartridge unit 1 individually or to supply power to two atomizing cores 12 in the cartridge unit 1 simultaneously via the power supply unit 2 is mainly controlled by a preset program and corresponding control buttons. Since the relevant technology is relatively common in the field of electronic cigarettes and belongs to the prior art, its specific circuit structure will not be described in detail in this utility model.

[0065] The above description is only a preferred embodiment of the present utility model and is 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.
