Description

Technical Field

[0001] This utility model relates to the field of electronic cigarette technology, and in particular to a dual-chamber independent airway electronic cigarette. Background Technology

[0002] In existing technologies, e-cigarettes, as a product to replace traditional tobacco, are increasingly focusing on improving user experience. Among them, dual-chamber e-cigarettes are favored by the market because they can simultaneously provide two different flavored e-liquids. To achieve independent operation of the two chambers and avoid flavor mixing, one of the core key technologies lies in the design and control of independent airways.

[0003] Currently, there are two main technical solutions for achieving independent airflow in dual-chamber atomizers: The first is a dual-microphone (airflow sensor) control scheme, where each atomizer chamber has its own independent microphone to detect inhalation airflow and control the corresponding atomizer coil. The drawback of this scheme is the need for two microphones, which increases hardware material costs and makes the mainboard circuit design more complex, resulting in a higher overall cost. The second is a single-microphone flying wire scheme, which uses only one microphone, but attaches it to the silicone airflow channel on the upper part of the e-liquid cup via a flying wire to detect airflow. While this scheme saves the cost of one microphone, the "flying wire" process has significant drawbacks: firstly, the flying wire connection is cumbersome during assembly, resulting in low production efficiency and a high risk of errors; secondly, the flying wire connection poses reliability risks during long-term use, such as wire breakage or loose connections, leading to poor product stability and a higher failure rate. In addition, most existing dual-chamber e-cigarettes can only allow one of the left or right chambers to work at a time, meaning that only one flavor can be selected each time you vape. They cannot achieve the effect of having both atomizing chambers work at the same time to produce a mixed flavor, which is insufficient in terms of the playability and innovation of the flavor.

[0004] Existing dual-chamber independent airway electronic cigarettes suffer from high manufacturing costs, complex assembly processes, poor stability, and the inability to achieve simultaneous operation of both atomizing chambers to produce a mixed flavor effect. No effective solution has yet been proposed. Utility Model Content

[0005] In view of this, it is necessary to provide a dual-chamber independent airway electronic cigarette to at least solve the problems of existing dual-chamber independent airway electronic cigarettes, such as high manufacturing cost, complicated assembly process, poor stability, and inability to achieve the effect of two atomizing chambers working simultaneously to produce a mixed flavor.

[0006] This utility model provides a dual-chamber independent airway electronic cigarette, including a shell, an oil cup, and a lower fixing bracket. The oil cup and the lower fixing bracket are both disposed within the shell. The oil cup includes a left oil reservoir and a right oil reservoir arranged side-by-side independently. The left oil reservoir has a left atomization channel in its center, and the right oil reservoir has a right atomization channel in its center. The lower fixing bracket covers the bottom of the oil cup, forming an independently arranged left atomization chamber and a right atomization chamber between the lower fixing bracket and the oil cup. The left oil reservoir is connected to the left atomization channel through the left atomization chamber, and the right oil reservoir is connected to... The right atomizing chamber is connected to the right atomizing channel; the lower fixed bracket is provided with a left air inlet and a right air inlet, the left air inlet is connected to the left atomizing chamber, and the right air inlet is connected to the right atomizing chamber; the lower fixed bracket is provided with an adjusting valve; wherein, the adjusting valve is used to control the left air inlet and the right air inlet to open synchronously, so that the left atomizing channel and the right atomizing channel can be air-introduced synchronously, and to control one of the left air inlet and the right air inlet to open, so that one of the left atomizing channel and the right atomizing channel can be air-introduced accordingly.

[0007] In some embodiments, an atomizing assembly is further included, each comprising a left atomizing assembly and a right atomizing assembly. The left atomizing assembly includes a left atomizing core and a left reservoir cotton. The left atomizing core is disposed within the left atomizing channel, and the left reservoir cotton is disposed within the left atomizing cavity and covers the outer peripheral sidewall of the left atomizing core. The right atomizing assembly includes a right atomizing core and a right reservoir cotton. The right atomizing core is disposed within the right atomizing channel, and the right reservoir cotton is disposed within the right atomizing cavity and covers the outer peripheral sidewall of the right atomizing core. E-liquid from the left reservoir flows into the left atomizing cavity, is adsorbed onto the left reservoir cotton, and is atomized by the left atomizing core within the left atomizing channel. E-liquid from the right reservoir flows into the right atomizing cavity, is adsorbed onto the right reservoir cotton, and is atomized by the right atomizing core within the right atomizing channel.

[0008] In some embodiments, a mouthpiece is also included, which is fitted onto the upper end of the outer shell and is sealed to the oil cup via an upper sealing silicone piece. The mouthpiece has a left adsorption channel and a right adsorption channel inside, the left atomizing channel is connected to the left adsorption channel, and the right atomizing channel is connected to the right adsorption channel. Both the left and right adsorption channels have connecting holes, and the left and right adsorption channels are interconnected through the connecting holes. When the left and right atomizing channels work simultaneously, the smoke mixes with the smoke through the left and right adsorption channels before entering the human body.

[0009] In some embodiments, a control motherboard is also included, on which a microphone is provided. The microphone is provided with a microphone sealing silicone piece on its exterior. The oil cup is provided with an independent channel. The upper end of the independent channel is connected to the suction nozzle, and the lower end of the independent channel is connected to the microphone through the microphone sealing silicone piece. When the user sucks on the suction nozzle, the suction airflow passes through the independent channel to trigger the microphone, thereby activating the control motherboard.

[0010] In some embodiments, the left atomizing component and the right atomizing component are electrically connected to the control main board, and the control main board is provided with a toggle switch, which is kinetically connected to the regulating valve; wherein, by toggling the regulating valve, the toggle switch is activated, so that the control main board drives the left atomizing component or the right atomizing component to work.

[0011] In some embodiments, a power supply device is also included, which is electrically connected to the control motherboard; wherein the power supply device is used to provide a power source for the control motherboard, the left atomizing component, and the right atomizing component.

[0012] In some embodiments, the control motherboard is provided with a charging port, which is electrically connected to the power supply device through the control motherboard; wherein, the charging port is used to charge the power supply device.

[0013] In some embodiments, the lower fixing bracket and the oil storage tank are sealed together by a lower sealing silicone element to prevent the e-liquid in the oil storage tank from leaking out from the lower fixing bracket.

[0014] In some embodiments, the lower fixed bracket and the regulating valve are sealed together by an air inlet sealing silicone element.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: The embodiments of this application provide a dual-chamber independent airway electronic cigarette with a novel structure and reasonable design, which has the following advantages: 1. Significantly reduced costs and simplified assembly, improving product stability: This utility model adopts a single microphone and independent dual atomization air guide design. The main board and single microphone are installed below the oil cup and the lower fixed bracket. Then, through an independent channel opened inside the oil cup, the trigger airflow is precisely guided from the nozzle to the microphone position. This completely eliminates the high cost problem of the "dual microphone" solution and the assembly difficulties and reliability risks of the "flying wire" solution. All circuit connections are centralized and reliable, eliminating the need for flying wires. This significantly reduces material costs, greatly simplifies the assembly process, and improves production efficiency, product consistency, and long-term stability.

[0016] 2. Flexible working mode switching greatly enriches the flavor experience: This utility model introduces a mechanically linked air regulating valve structure. By toggling the air regulating valve, users can simultaneously switch between the air path and the electrical circuit. The air regulating valve directly controls the opening and closing of the left and right air inlets, thereby achieving physical switching between three modes: left chamber operation, right chamber operation, or simultaneous operation of both chambers. Furthermore, the air regulating valve is mechanically linked with the toggle switch on the main board, switching the working mode of the electrical circuit while switching the air path, ensuring complete synchronization between the air path and the electrical circuit. This allows users to not only enjoy the traditional, independent flavor sucking experience without interference, but also experience the new mixed flavor produced by simultaneous operation of both chambers, greatly enhancing the product's fun and flavor playability, and meeting users' demand for novel experiences.

[0017] 3. Compact structure, excellent sealing, and high reliability: A complete sealing system is formed by using upper sealing silicone parts, lower sealing silicone parts, and air intake sealing silicone parts. This not only effectively prevents e-liquid leakage but also ensures the sealing of each independent air passage. This ensures that the left and right chambers will not mix flavors in any working mode, and the airflow signal can be accurately transmitted to the microphone to trigger the device. The air regulating valve and the lower fixed bracket are sealed together by the air intake sealing silicone parts, ensuring smooth operation and reliable sealing. This guarantees the durability and effectiveness of the mode switching function and makes it highly practical. Attached Figure Description

The term "or / and" as used herein includes any and all combinations of one or more of the associated listed items.

[0023] See Figure 1-5This application provides a dual-chamber independent airway electronic cigarette, including a shell 100, an oil cup 200, and a lower fixing bracket 300. The oil cup 200 and the lower fixing bracket 300 are both located within the shell 100. The oil cup 200 includes a left oil reservoir 21 and a right oil reservoir 22 arranged side-by-side independently. The left oil reservoir 21 has a left atomization channel 23 in its center, and the right oil reservoir 22 has a right atomization channel 24 in its center. The lower fixing bracket 300 covers the bottom of the oil cup 200, forming an independently arranged left atomization chamber 25 and a right atomization chamber 26 between the lower fixing bracket 300 and the oil cup 200. The left oil reservoir 21 is connected to the left atomization channel 24 through the left atomization chamber 25. The right oil storage tank 22 is connected to the right atomizing channel 24 via the right atomizing chamber 26. The lower fixed bracket 300 is provided with a left air inlet 31 and a right air inlet 32. The left air inlet 31 is connected to the left atomizing chamber 25, and the right air inlet 32 ​​is connected to the right atomizing chamber 26. The lower fixed bracket 300 is provided with a regulating valve 33. The regulating valve 33 is used to control the left air inlet 31 and the right air inlet 32 ​​to open synchronously so that the left atomizing channel 23 and the right atomizing channel 24 can be filled with air synchronously. It is also used to control one of the left air inlet 31 and the right air inlet 32 ​​to open so that one of the left atomizing channel 23 and the right atomizing channel 24 can be filled with air.

[0024] It should be noted that with this configuration, when the regulating valve 33 is adjusted to the middle position, either the left air inlet 31 or the right air inlet 32 ​​is simultaneously open, allowing air to enter both the right atomizing channel 24 and the left atomizing channel 23 at the same time. When the regulating valve 33 is adjusted to the left side, the left air inlet 31 is closed, and the right air inlet 32 ​​is open, allowing air to enter the right atomizing channel 24 in a single channel. When the regulating valve 33 is adjusted to the right side, the right air inlet 32 ​​is closed, and the left air inlet 31 is open, allowing air to enter the left atomizing channel 23 in a single channel. A mechanically linked air regulating valve 33 structure is introduced, allowing the user to adjust the air regulating valve 33... This allows for simultaneous switching between the air and electrical circuits. The air regulating valve 33 directly controls the opening and closing of the left air inlet 31 and the right air inlet 32, thereby enabling physical switching between three modes: operation of the left chamber (left oil storage chamber 21, left atomizing channel 23 and left atomizing chamber 25), operation of the right chamber (right oil storage chamber 22, right atomizing channel 24 and right atomizing chamber 26), or simultaneous operation of both chambers. This allows users to not only enjoy the traditional, independent flavor vaping experience without interference, but also experience the new mixed flavors produced by the simultaneous operation of both chambers, greatly enhancing the product's fun and playability, and satisfying users' demand for novel experiences.

[0025] To achieve the dual-chamber e-liquid atomization function, some optional embodiments further include an atomization assembly 400. Each atomization assembly 400 includes a left atomization assembly 41 and a right atomization assembly 42. The left atomization assembly 41 includes a left atomizing core 411 and a left reservoir cotton 412. The left atomizing core 411 is located within the left atomization channel 23, and the left reservoir cotton 412 is located within the left atomization chamber 25 and covers the outer peripheral sidewall of the left atomizing core 411. The right atomization assembly 42 includes a right atomizing core 421 and a right reservoir cotton. 422, the right atomizing core 421 is located in the right atomizing channel 24, and the right oil-retaining cotton 422 is located in the right atomizing chamber 26 and covers the outer peripheral side wall of the right atomizing core 421; wherein, the e-liquid in the left oil-retaining tank 21 flows into the left atomizing chamber 25 and is adsorbed on the left oil-retaining cotton 412 and atomized through the left atomizing core 411 in the left atomizing channel 23; the e-liquid in the right oil-retaining tank 22 flows into the right atomizing chamber 26 and is adsorbed on the right oil-retaining cotton 422 and atomized through the right atomizing core 421 in the right atomizing channel 24.

[0026] It should be noted that this setup uses independent and non-interfering left atomizing component 41 and right atomizing component 42. Both left atomizing component 41 and right atomizing component 42 adopt a structure design of atomizing core and oil storage cotton. The atomizing core atomizes the e-liquid absorbed by the oil storage cotton, thereby achieving the atomization function.

[0027] To enhance the flavor mixing effect during inhalation, some optional embodiments include a mouthpiece 500, which covers the upper end of the oil cup 200. The mouthpiece 500 and the oil cup 200 are sealed together by an upper sealing silicone part 600. The mouthpiece 500 has a left adsorption channel 51 and a right adsorption channel 52 inside. The left atomizing channel 23 is connected to the left adsorption channel 51, and the right atomizing channel 24 is connected to the right adsorption channel 52. Both the left adsorption channel 51 and the right adsorption channel 52 are provided with connecting holes 53, and the left adsorption channel 51 and the right adsorption channel 52 are interconnected through the connecting holes 53. When the left atomizing channel 23 and the right atomizing channel 24 are working simultaneously, the smoke is mixed through the left adsorption channel 51 and the right adsorption channel 52 before entering the human body.

[0028] To achieve precise control, some optional embodiments also include a control board 700, which has a microphone and a microphone sealing silicone part 71 on its exterior. The oil cup 200 has an independent channel 27, the upper end of which is connected to the nozzle 500, and the lower end of which is connected to the microphone through the microphone sealing silicone part 71. When the user sucks through the nozzle 500, the suction airflow passes through the independent channel 27 to trigger the microphone, thereby activating the control board 700.

[0029] It should be noted that this setup employs a single microphone and independent dual atomization airflow design. The mainboard 700 and the single microphone are installed below the oil cup 200 and the lower fixing bracket 300. Then, through an independent channel 27 opened inside the oil cup 200, the trigger airflow is precisely guided from the mouthpiece to the microphone position. This completely eliminates the high cost problem of the "dual microphone" solution and the assembly difficulties and reliability risks of the "flying wire" solution. All circuit connections are centralized and reliable, eliminating the need for flying wires. This significantly reduces material costs, greatly simplifies the assembly process, and improves production efficiency, product consistency, and long-term stability.

[0030] To further achieve precise control, in some optional embodiments, the left atomizing component 41 and the right atomizing component 42 are electrically connected to the control main board 700. The control main board 700 is equipped with a toggle switch 72, which is connected to the regulating valve 33. By toggling the regulating valve 33, the toggle switch 72 is activated, thereby enabling the control main board 700 to drive the left atomizing component 41 or the right atomizing component 42 to work.

[0031] It should be noted that with this configuration, the air regulating valve 33 and the toggle switch 72 on the main board 700 are mechanically linked, switching the working mode of the circuit while switching the air path, ensuring that the states of the air path and the circuit are completely synchronized.

[0032] In order to enable the electronic cigarette to continue to operate, some optional embodiments also include a power supply device 800, which is electrically connected to the control motherboard 700; wherein, the power supply device 800 is used to provide power to the control motherboard 700, the left atomizing component 41 and the right atomizing component 42.

[0033] To further enhance the power supply and battery life of electronic cigarettes, in some optional embodiments, the control motherboard 700 is provided with a charging port 73, which is electrically connected to the power supply device 800 through the control motherboard 700; wherein, the charging port 73 is used to charge the power supply device 800.

[0034] To improve the overall sealing of the electronic cigarette, in some alternative embodiments, the lower fixing bracket 300 and the oil cup 200 are sealed together by a lower sealing silicone part 900 to prevent the e-liquid in the oil cup 200 from leaking out from the lower fixing bracket 300.

[0035] To improve the overall sealing of the electronic cigarette, in some alternative embodiments, the lower fixed bracket 300 and the regulating valve 33 are sealed together by an air intake sealing silicone piece 34.

[0036] It should be noted that this configuration, using the upper sealing silicone part 600, the lower sealing silicone part 900, and the air intake sealing silicone part 34, constitutes a complete sealing system. This not only effectively prevents e-liquid leakage but also ensures the sealing of each independent air passage, ensuring that the left and right chambers will not mix flavors in any working mode. Furthermore, the airflow signal can be accurately transmitted to the microphone to trigger the device to work. The air regulating valve 33 and the lower fixed bracket 300 are sealed together by the air intake sealing silicone part 34, ensuring smooth operation and reliable sealing, thus guaranteeing the durability and effectiveness of the mode switching function.
