Description

Technical Field

[0001] This application relates to the field of electronic cigarettes, and in particular to an electronic cigarette device and a method for controlling the flow of smoke. Background Technology

[0002] Electronic cigarettes are a new type of tobacco product that replaces the traditional cigarette burning process by heating e-liquid. While releasing aroma and nicotine, the release of tar and other harmful components is significantly reduced compared to traditional cigarettes.

[0003] During the use of e-cigarettes, different users have different inhalation methods, resulting in different vapor flow rates, which in turn leads to different users having different needs for the amount of e-liquid atomized. However, currently common e-cigarette devices control the amount of e-liquid atomized by the user adjusting the power of the heating coil, which makes it difficult to adjust the amount of e-liquid atomized according to the changes in vapor flow during inhalation, resulting in a less smooth and natural smoking experience for the user. Summary of the Invention

[0004] In order to improve the problem that current electronic cigarettes cannot adjust the amount of e-liquid atomized according to the changes in the smoke flow rate during inhalation, this application provides an electronic cigarette device and a smoke flow control method.

[0005] The electronic cigarette device provided in this application adopts the following technical solution:

[0006] An electronic cigarette device, comprising:

[0007] The outer casing has a cartridge connected to one end and a mouthpiece provided at the other end.

[0008] A vortex atomizer is rotatably mounted in the housing. The vortex atomizer includes a conduit, an atomizing disc, and a smoke guide column connected coaxially in sequence. One end of the conduit passes through the atomizing disc, and the other end extends to the bottom of the cartridge. The smoke guide column has a spiral smoke guide groove around its own arc surface. An oil outlet is provided at the end of the smoke guide column near the atomizing disc, and the oil outlet is connected to the conduit. The atomizing disc is provided with an atomizing structure for dispersing e-liquid droplets into a mist as the atomizing disc rotates.

[0009] A driving device is used to drive the vortex atomizer to rotate;

[0010] A pressure sensor is used to detect the air pressure at the smoke outlet of the vortex atomizer;

[0011] A controller, connected to the pressure sensor and the drive device, is used to adjust the rotation speed of the vortex atomizer according to the air pressure change at the smoke outlet of the vortex atomizer;

[0012] A flow-guiding structure is used to allow incompletely atomized e-liquid to flow back into the cartridge.

[0013] During the high-speed rotation of the vortex atomizer, the smoke guide column with spiral smoke guide grooves rotates, causing negative pressure to be generated at the opening of the oil outlet. The e-liquid in the cartridge is forced into the guide tube and then flung out from the oil outlet. The atomizing structure disperses the e-liquid droplets into a mist as the atomizing disc rotates. The e-liquid that is not completely atomized flows back into the cartridge under the action of the flow guide structure, realizing the recycling of e-liquid.

[0014] When a user inhales through the mouthpiece, a pressure sensor collects the pressure drop information inside the casing and transmits it to the controller. The controller controls the rotation of the vortex atomizer and adjusts its speed based on the pressure drop. The higher the speed of the vortex atomizer, the greater the amount of e-liquid atomized, and the greater the flow of vapor delivered to the mouthpiece through the smoke guide. Conversely, the lower the speed of the vortex atomizer, the smaller the flow of vapor. This application can adjust the speed of the vortex atomizer in real time according to the pressure drop generated by the user's inhalation, thereby adjusting the flow of vapor in real time, avoiding waste of e-liquid resources, and improving the smoothness of the user's inhalation.

[0015] Furthermore, the atomizing structure includes a plurality of atomizing blocks spaced apart circumferentially along the atomizing disc; when the vortex atomizer rotates to fling e-liquid out of the outlet, the atomizing blocks are located on the trajectory of the e-liquid.

[0016] When the atomizing disc rotates, multiple atomizing blocks move in a circular motion around the axis of the atomizing disc. The e-liquid ejected from the oil outlet collides with the high-speed moving atomizing blocks, breaking the e-liquid droplets into smaller droplets, thus achieving atomization of the e-liquid.

[0017] Furthermore, a return groove is provided on the periphery of the atomizing disc, and the return groove is parallel to the axial direction of the atomizing disc; a gap is provided between the outlet end of the cartridge and the outer wall of the conduit for the e-liquid to pass through, and the flow guiding structure is used to guide the e-liquid flowing along the return groove to the outlet end of the cartridge through the gap into the cartridge.

[0018] Incompletely atomized e-liquid droplets flow along the inner wall of the outer shell to the atomizing disc. Under its own gravity, the e-liquid flows along the return channel to the outlet end of the cartridge. The guide structure further guides the e-liquid through the gaps into the cartridge, realizing the recycling of e-liquid.

[0019] Furthermore, multiple return channels are provided, and the multiple return channels are distributed at intervals along the circumference of the atomizing disk.

[0020] E-liquid can be recycled along multiple return channels, which helps improve the recycling efficiency of e-liquid.

[0021] Furthermore, a conical portion is fixedly provided on the side of the atomizing disc near the cartridge, and the flow guiding structure includes a plurality of arc-shaped grooves formed on the conical portion, one end of the arc-shaped groove being connected to the gap and the other end being connected to the return groove.

[0022] During use, the device is usually in an upright position, with the mouthpiece on top and the cartridge on the bottom. At this time, the unvaporized e-liquid flows through the return channel and the arc-shaped channel under its own gravity and into the gap at the outlet of the cartridge. At the same time, the atomizing disc rotates, and the conical part and the arc-shaped channel work together to generate airflow towards the cartridge. The thrust of the airflow and the weight of the e-liquid itself form a combined force, forcing the e-liquid through the gap into the cartridge, thus realizing the recycling of the e-liquid.

[0023] When the e-cigarette is inverted during transportation, with the cartridge on top and the mouthpiece below, the e-liquid in the cartridge is unlikely to leak through gaps into the outer shell due to its own weight. Even if a small amount of e-liquid leaks into the outer shell due to vibration, its viscosity causes it to adhere to the surface of the conical part. Furthermore, the multiple arc-shaped grooves on the conical part increase the contact area between the conical part and the e-liquid, resulting in a more dispersed distribution of the e-liquid on the surface. This prevents it from coalescing into large droplets that flow along the return channel to the other side of the atomizing plate. Thus, leakage when the e-cigarette is inverted is minimized.

[0024] Furthermore, a plurality of flow channels are provided on the inner sidewall of the outer shell, and the flow channels extend from the mouthpiece toward the atomizing disc.

[0025] The flow channel guides the flow of e-liquid, making it easier for the e-liquid adhering to the inner wall of the outer shell to flow to the atomizing disc.

[0026] Furthermore, the end of the conduit away from the cartridge extends into the smoke guide column and the port is closed. The distance between the oil outlet and the closed end of the conduit is 1 / 4 to 1 / 3 of the conduit length.

[0027] Because the open end of the conduit extends to the bottom of the cartridge, when the device is inverted, only a small amount of e-liquid from the bottom of the cartridge will flow into the conduit. As the e-liquid flows through the outlet hole along the conduit, an oil film forms at the outlet hole, sealing it and preventing e-liquid from leaking out. Subsequently, the e-liquid in the conduit gathers at the closed end of the conduit under the influence of gravity, thus minimizing e-liquid leakage when the device is inverted.

[0028] Furthermore, a temperature sensor and a heating device are installed on the inner sidewall of the housing at the smoke outlet end of the vortex atomizer, and both the temperature sensor and the heating device are connected to the controller.

[0029] Temperature sensors can detect the temperature of the flue gas and transmit the temperature information to the controller. The controller adjusts the power of the heating device to heat the flue gas, which helps to improve the user's smoking experience.

[0030] Furthermore, a flow sensor is installed at the smoke outlet of the vortex atomizer, and the flow sensor is connected to the controller.

[0031] During the use of electronic cigarettes, the controller integrates information collected by the pressure sensor and flow sensor to control the rotation speed of the vortex atomizer in real time.

[0032] This application provides a method for controlling the smoke flow of an electronic cigarette device, comprising the following steps:

[0033] Inhalation and initial pressure drop detection: When the user starts using the cigarette, the pressure sensor collects the pressure drop information inside the housing and transmits the information to the controller.

[0034] Atomization: The controller controls the rotation of the vortex atomizer and adjusts its speed according to the pressure drop, so as to atomize the e-liquid;

[0035] Real-time pressure drop and flow detection: During use, the pressure sensor and flow sensor collect pressure drop information and flue gas flow information in real time, respectively, and transmit the information to the controller. The controller integrates the information collected by the pressure sensor and flow sensor to control the rotation speed of the cyclone atomizer in real time.

[0036] E-liquid recycling: The flow guiding structure allows unvaporized e-liquid to flow back into the cartridge.

[0037] In summary, this application includes at least one of the following beneficial technical effects:

[0038] 1. When a user inhales through the mouthpiece, the pressure sensor collects the pressure drop information inside the housing and transmits the information to the controller. The controller controls the rotation of the vortex atomizer and adjusts its speed according to the magnitude of the pressure drop. The flow rate of the vapor changes with the speed of the vortex atomizer. This allows the flow rate of the vapor to be adjusted in real time according to the pressure drop generated by the user's inhalation, avoiding waste of e-liquid resources and improving the smoothness of the user's inhalation.

[0039] 2. By setting up structures such as guide channels, return channels, and arc-shaped channels, the incompletely atomized e-liquid is recycled back into the e-liquid cartridge, reducing e-liquid waste;

[0040] 3. By setting up structures such as conical parts and arc-shaped grooves, as well as special designs for the conduit and oil outlet, leakage of e-liquid is minimized when the e-cigarette is inverted. Attached Figure Description

Detailed Implementation

[0048] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0049] Example 1

[0050] This application discloses an electronic cigarette device. (Refer to...) Figure 1 and Figure 2 The electronic cigarette device includes a housing 1 and a vortex atomizer 4 rotatably disposed in the housing 1. One end of the housing 1 is connected to a cartridge 2, and the other end is provided with a mouthpiece 3. The mouthpiece 3 has multiple smoke outlets 31 for filtering large-sized atomized particles.

[0051] Reference Figure 2 and Figure 3 The vortex atomizer 4 includes a conduit 41, an atomizing disc 42, and a smoke guide column 43 connected coaxially in sequence. One end of the conduit 41 passes through the atomizing disc 42, and the other end extends to the bottom of the cartridge 2. The smoke guide column 43 has a spiral smoke guide groove 431 around its own arc surface. The end of the smoke guide column 43 near the atomizing disc 42 has multiple oil outlet holes 432 that communicate with the conduit 41, and the multiple oil outlet holes 432 are arranged at intervals along the circumference of the smoke guide column 43.

[0052] Reference Figure 3The atomizing disc 42 is provided with an atomizing structure for dispersing e-liquid droplets into a mist as the atomizing disc 42 rotates. Specifically, the atomizing structure includes multiple atomizing blocks 421 spaced circumferentially along the atomizing disc 42. When the vortex atomizer 4 rotates and causes the e-liquid to be ejected from the outlet 432, the atomizing blocks 421 are located on the trajectory of the e-liquid. The smoke guide 431, the outlet 432, and the atomizing blocks 421 are all located in the same connected space.

[0053] The cyclone atomizer 4 can be made of high-strength, lightweight aluminum alloy material that is corrosion-resistant, high-temperature resistant, and wear-resistant. It is low in cost and suitable for mass production.

[0054] The cartridge 2 is equipped with a drive device (not shown in the figure), which can be a micro servo motor used in conjunction with gears to drive the vortex atomizer 4 to rotate.

[0055] Furthermore, the vortex atomizer 4 is equipped with a flow guiding structure to allow the incompletely atomized e-liquid to flow back into the cartridge 2.

[0056] Reference Figure 3 and Figure 4 The outer shell 1 is segmented with varying diameters. Specifically, along the direction from the cartridge 2 to the mouthpiece 3, the outer shell 1 contains a reflux chamber 11, a receiving chamber 12, an atomizing chamber 13, and a smoke delivery chamber 14. The atomizing disc 42 is rotatably disposed in the receiving chamber 12, and the smoke guide column 43 is rotatably disposed in the smoke delivery chamber 14. Both the reflux chamber 11 and the atomizing chamber 13 are conical, and their conical directions are opposite. The conical reflux chamber 11 facilitates the collection and reflux of un-atomized e-liquid, while the conical atomizing chamber 13 facilitates the collection and flow of smoke towards the smoke delivery chamber 14.

[0057] During the high-speed rotation of the vortex atomizer 4, the smoke guide column 43 with the spiral smoke guide groove 431 rotates, and the airflow in the smoke delivery chamber 14 is generated towards the mouthpiece 3, which causes negative pressure to be generated at the opening of the oil outlet 432. The e-liquid in the cartridge 2 is forced into the guide tube 41 and then sprayed out from the oil outlet 432. Under the action of centrifugal force, the e-liquid flies out in all directions, and then collides with the high-speed moving atomizing block 421 and disperses into small droplets, thus realizing the atomization of the e-liquid.

[0058] Reference Figure 2 A pressure sensor 5 and a flow sensor 6 are installed at the smoke outlet of the vortex atomizer 4. Both the pressure sensor 5 and the flow sensor 6 are connected to a controller. The controller is connected to the drive unit and is used to adjust the rotation speed of the vortex atomizer 4 according to the changes in air pressure and flow rate at the smoke outlet of the vortex atomizer 4. The controller can be installed on the outer surface of the housing 1 for convenient human-machine interaction.

[0059] When the user starts using the device, they inhale through the mouthpiece 3. The pressure sensor 5 collects the pressure drop information at the outlet of the smoke delivery chamber 14 and transmits this information to the controller. The controller controls the rotation of the vortex atomizer 4 and adjusts its speed based on the pressure drop. During the use of the electronic cigarette, the pressure sensor 5 and the flow sensor 6 collect pressure drop information and smoke flow information in real time, respectively, and transmit this information to the controller. The controller combines the information collected by the pressure sensor 5 and the flow sensor 6 to control the speed of the vortex atomizer 4 in real time.

[0060] The higher the rotation speed of the vortex atomizer 4, the greater the amount of e-liquid atomized, and the greater the flow of vapor delivered to the mouthpiece 3 through the smoke guide 431; conversely, the lower the rotation speed of the vortex atomizer 4, the smaller the flow of vapor. This application can adjust the rotation speed of the vortex atomizer 4 in real time according to the pressure drop and vapor flow generated by the user's inhalation, thereby adjusting the vapor flow in real time, avoiding waste of e-liquid resources, and improving the smoothness of the user's inhalation.

[0061] When using the device, small-sized atomized particles that meet the requirements can be inhaled by the user through the smoke outlet 31, while large-sized atomized particles are isolated in the smoke duct. The large-sized atomized particles condense into droplets, which can be re-atomized after flowing back to the atomizing plate 42, or return to the cartridge 2 through the guide structure. This ensures the user's health without wasting e-liquid resources.

[0062] Reference Figure 2 and Figure 4 Multiple flow channels 15 are provided on the inner wall of the outer shell 1, extending from the mouthpiece 3 towards the atomizing plate 42. The flow channels 15 guide the flow of e-liquid, facilitating the flow of e-liquid adhering to the inner wall of the outer shell 1 towards the atomizing plate 42.

[0063] To achieve e-liquid recycling, refer to Figure 3 and Figure 5 The atomizing disc 42 has multiple return grooves 422 on its circumference, which are parallel to the axial direction of the atomizing disc 42 and are spaced apart along the circumference of the atomizing disc 42. A gap 21 for e-liquid to pass through is provided between the outlet end of the cartridge 2 and the outer wall of the conduit 41. The flow guiding structure is used to guide the e-liquid flowing along the return grooves 422 to the outlet end of the cartridge 2 through the gap 21 into the cartridge 2.

[0064] Specifically, refer to Figure 5 A conical part 44 is fixedly provided on the side of the atomizing disc 42 near the cartridge 2. The flow guiding structure includes multiple arc-shaped grooves 441 opened on the conical part 44. One end of the arc-shaped groove 441 is connected to the gap 21 and the other end is connected to the return groove 422.

[0065] During normal use and storage, the e-cigarette is usually in an upright position, with the mouthpiece 3 on top and the cartridge 2 on the bottom. After use, the unvaporized e-liquid flows under its own weight through the return channel 422 and the arc-shaped channel 441 into the gap 21 at the outlet end of the cartridge 2. The drive device drives the vortex atomizer 4 to rotate in the opposite direction. The conical part 44 cooperates with the arc-shaped channel 441 to generate an airflow in the return chamber 11 towards the cartridge 2. The thrust of the airflow and the weight of the e-liquid combine to force the e-liquid through the gap 21 into the cartridge 2, thus achieving e-liquid recycling.

[0066] When the smoking device is inverted during transportation, with the cartridge 2 on top and the mouthpiece 3 on the bottom, the e-liquid in the cartridge 2 is unlikely to enter the return chamber 11 through the gap 21 due to its own gravity, thus preventing e-liquid leakage.

[0067] Even if a small amount of e-liquid leaks from the outlet of cartridge 2 into the return chamber 11 due to vibration or other reasons, the e-liquid, due to its viscosity, will adhere to the surface of the conical part 44. Furthermore, because the conical part 44 has multiple arc-shaped grooves 441, the contact area between the conical part 44 and the e-liquid is increased, resulting in a more dispersed distribution of the e-liquid on the surface of the conical part 44. This prevents the e-liquid from coalescing into large droplets that flow further along the return groove 422 to the other side of the atomizing plate 42. In this way, e-liquid leakage is minimized when the device is inverted.

[0068] To further prevent e-liquid leakage when the smoking device is inverted, please refer to... Figure 2 The end of the conduit 41 away from the cartridge 2 extends into the smoke guide column 43 and the port is closed. The distance between the oil outlet 432 and the closed end of the conduit 41 is 1 / 4 of the length of the conduit 41.

[0069] Since the open end of the conduit 41 extends to the bottom of the cartridge 2, when the device is inverted, only a small amount of e-liquid at the bottom of the cartridge 2 will flow into the conduit 41. When the e-liquid flows through the oil outlet 432 along the conduit 41, an oil film is formed at the oil outlet 432, sealing the oil outlet 432 and preventing the e-liquid from leaking out of the oil outlet 432. Subsequently, the e-liquid in the conduit 41 gathers to the closed end of the conduit 41 under the action of gravity and will not leak out.

[0070] Reference Figure 2 A temperature sensor 7 and a heating device 8 are installed on the inner side wall of the outer shell 1 at the smoke outlet end of the vortex atomizer 4. Both the temperature sensor 7 and the heating device 8 are connected to the controller.

[0071] Temperature sensor 7 detects the temperature of the smoke and transmits the temperature information to the controller. The controller adjusts the power of heating device 8 to heat the smoke, which helps improve the user's smoking experience. The outer shell 1 is made of heat-insulating ceramic, which helps prevent the temperature of the outer shell 1 from rising when the heating device 8 is working and affecting the use of the smoking device.

[0072] This application uses swirling atomization instead of the common heating atomization method, which makes it easier to control the temperature of the smoke and avoids the smoke being too cold or too hot.

[0073] The implementation principle of an electronic cigarette device according to an embodiment of this application is as follows: During the high-speed rotation of the vortex atomizer 4, the smoke guide column 43 with the spiral smoke guide groove 431 rotates, causing negative pressure to be generated at the opening of the oil outlet 432. The e-liquid in the cartridge 2 is forced into the guide tube 41 and then thrown out from the oil outlet 432. The atomizing block 421 rotates with the atomizing disc 42 to disperse the e-liquid droplets into a mist. The e-liquid that is not completely atomized flows back into the cartridge 2 under the action of the flow guide structure, realizing the recycling of e-liquid.

[0074] When a user inhales through the mouthpiece 3, the pressure sensor 5 collects the pressure drop information inside the housing 1 and transmits the information to the controller. The controller controls the rotation of the vortex atomizer 4 and adjusts its speed according to the magnitude of the pressure drop. The flow rate of the vapor changes with the speed of the vortex atomizer 4, avoiding waste of e-liquid resources and improving the smoothness of the user's inhalation of vapor.

[0075] Example 2

[0076] This application discloses a method for controlling the smoke flow of an electronic cigarette device, referring to... Figure 6 This includes the following steps:

[0077] Suction and initial pressure drop detection steps: When starting use, the user inhales through the mouthpiece 3, and the pressure sensor 5 collects the pressure drop information at the outlet of the smoke delivery chamber 14 and transmits the information to the controller;

[0078] Atomization steps: The controller controls the rotation of the vortex atomizer 4 and adjusts its speed according to the pressure drop to atomize the e-liquid for the user to inhale; the temperature sensor 7 detects the airflow temperature at the outlet of the smoke delivery chamber 14 in real time and transmits the information to the controller, which adjusts the power of the heating device 8 in real time.

[0079] Real-time pressure drop and flow detection steps: During use, pressure sensor 5 and flow sensor 6 collect pressure drop information and flue gas flow information in real time, respectively, and transmit the information to the controller. The controller integrates the information collected by pressure sensor 5 and flow sensor 6 and controls the rotation speed of cyclone atomizer 4 in real time.

[0080] When a non-zero voltage drop is detected, the real-time voltage drop and flow detection steps are repeated; when a zero voltage drop is detected, all devices enter standby mode.

[0081] E-liquid recycling steps: Incompletely atomized e-liquid flows back to the atomizing disc 42 for re-atomization, or flows back into the cartridge 2 through the flow guide structure.

[0082] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
