Abstract
Description
Technical Field
[0001] This utility model relates to the field of dual-atomization electronic cigarettes, and more particularly to a dual-atomization electronic cigarette. Background Technology
[0002] Currently, most dual-atomizing e-cigarettes on the market adopt an integrated design of the main atomizer and the secondary atomizer. This design has obvious drawbacks: Firstly, because the e-liquid in the secondary atomizer and the main atomizer are difficult to match perfectly, the e-liquid consumption rate is inconsistent at different power levels. Once the e-liquid in the secondary atomizer runs out and a burnt taste appears, the entire device cannot be used anymore, resulting in the waste of the remaining e-liquid in the main atomizer. Secondly, in order to match the e-liquid consumption rate of the two tanks, designers often make the secondary atomizer larger and overfill it with e-liquid, which directly leads to an increase in the size of the device and affects the user experience. Utility Model Content
[0003] In order to overcome the shortcomings of the existing technology, this utility model provides a solution that solves the problem of the entire device being scrapped due to the exhaustion of e-liquid in the second atomizer by using a detachable second atomizer.
[0004] The technical solution adopted by this utility model to solve its technical problem is:
[0005] A dual-atomizing electronic cigarette includes: a first housing; a bracket disposed within the first housing; a first atomizer fixedly mounted on the top of the bracket; and a detachably disposed second atomizer; wherein the bracket has a movable chamber for accommodating the second atomizer, the movable chamber being movable relative to the bracket; a first air passage is provided at the top of the bracket, and a second air passage is provided at the top of the movable chamber; when the second atomizer is installed in the movable chamber, the first air passage and the second air passage are in communication; when the second atomizer is detached from the movable chamber, the movable chamber moves relative to the bracket, causing the first air passage and the second air passage to be misaligned, thereby sealing the first air passage.
[0006] Furthermore, a sealing element is provided between the movable chamber and the support, the sealing element having a first sealing area and a second sealing area; when the first air passage is connected to the second air passage, the first sealing area abuts against the movable chamber and the support respectively to seal the connection between the first air passage and the second air passage; when the first air passage and the second air passage are misaligned, the second sealing area abuts against the movable chamber and the support respectively to seal the misalignment between the first air passage and the second air passage.
[0007] Furthermore, the first sealing region is arranged in a ring shape along the circumference of the second air passage, and the second sealing region surrounds the first sealing region; the inner diameter of the first sealing region is adapted to the outer diameter of the second air passage, and the inner edge of the second sealing region is spaced apart from the outer edge of the first sealing region.
[0008] Furthermore, a PCBA main board is provided on the side of the bracket away from the movable chamber. The PCBA main board is provided with conductive posts that protrude into the movable chamber. The second atomizer is provided with pins at corresponding positions. When the second atomizer is installed in the movable chamber, the conductive posts are electrically connected to the pins to enable the PCBA main board to control the second atomizer.
[0009] Furthermore, the PCBA mainboard is electrically connected to a light strip on the side away from the active chamber, as well as a button for controlling the output power of the second atomizer. The button is used to adjust the output power of the second atomizer, and the light strip indicates the current power level by the length of its light emission.
[0010] Furthermore, the movable chamber is provided with limiting protrusions on both sides; the bracket is provided with limiting grooves corresponding to the positions of the limiting protrusions; the movable chamber can slide along the limiting grooves to drive the second air passage to move relative to the first air passage.
[0011] Furthermore, the second atomizer is embedded in the movable chamber, which has an inner groove and an inner rib on the second atomizer. The inner rib engages with the inner groove. The second atomizer has a locking protrusion at the end away from the movable chamber, which protrudes from the movable chamber, making it easy to pull the second atomizer out by hand.
[0012] Furthermore, it also includes a second housing, which is fitted onto the first housing and can rotate relative to the first housing; the first housing has a first window and a second window, wherein the first window corresponds to the setting position of the light strip and is used to observe the light-emitting length of the light strip to confirm the output power of the second atomizer, and the second window corresponds to the position of the movable chamber and is used for the disassembly and assembly of the second atomizer; the second housing has a third window, and rotating the second housing can align the third window with the first window and the second window respectively, thereby selectively observing the light strip or operating the second atomizer.
[0013] Furthermore, the first housing is provided with a first positioning part, and the second housing is provided with a second positioning part. When the third window is aligned with the first window and the second window respectively, the first positioning part and the second positioning part engage with each other, thereby realizing the positioning of the second housing in two positions.
[0014] Furthermore, the first positioning part is a positioning protrusion, and the second positioning part is a positioning groove that cooperates with the positioning protrusion; two positioning protrusions are arranged at intervals along the circumference of the first housing, and two positioning grooves are arranged correspondingly along the circumference of the second housing; the positioning protrusion has an arc-shaped raised surface, and the positioning groove has an arc-shaped groove surface that matches the raised surface.
[0015] The beneficial effects of this utility model are:
[0016] This utility model of a dual-atomizing electronic cigarette features a detachable second atomizer within a movable chamber. This design allows the second atomizer to be freely installed and removed as needed. When the second atomizer is installed, the second airway of the movable chamber connects to the first airway at the top of the support, ensuring normal operation of the dual atomizer. When the second atomizer is removed, the movable chamber moves relative to the support, causing the first and second airways to be misaligned and sealing the first airway. This allows the first atomizer to be used independently. This not only solves the problem of the entire device becoming unusable due to the exhaustion of e-liquid in the second atomizer, but also enables free replacement of the second atomizer through a detachable structure. Furthermore, the second atomizer can be designed to be more compact, effectively avoiding the technical drawback of traditional dual-atomizing electronic cigarettes that have to be made large to accommodate e-liquid consumption.

[0032] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / linkages involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this utility model can be combined interactively without contradicting each other.
[0033] Reference Figure 1 , 2 A dual-atomizing electronic cigarette includes a first housing 100, a bracket 300 disposed within the first housing 100, a first atomizer 500 fixedly mounted on the top of the bracket 300, and a detachable second atomizer 600. By disassembling and replacing the second atomizer 600, users can replace and maintain the second atomizer 600 according to their individual needs.
[0034] Among them, reference Figure 1 , 34. The support 300 has a movable chamber 330 for accommodating the second atomizer 600, the movable chamber 330 being movable relative to the support 300; the top of the support 300 is provided with a first air passage 320, and the top of the movable chamber 330 is provided with a second air passage 332; when the second atomizer 600 is installed in the movable chamber 330, the first air passage 320 and the second air passage 332 are connected; when the second atomizer 600 is removed from the movable chamber 330, the movable chamber 330 moves relative to the support 300, causing the first air passage 320 and the second air passage 332 to be misaligned, thereby sealing the first air passage 320. In practical use, the user can fill the first atomizer 500 with commonly used e-liquid as a base flavor, while the second atomizer 600 can be replaced with different flavored e-liquids as needed to achieve flavor combinations and variations. For example, when a user wants to try a mint and citrus flavor combination, the second atomizer 600, filled with citrus-flavored e-liquid, can be mounted on the holder 300 and used in conjunction with the first atomizer 500, filled with mint-flavored e-liquid. When wanting to experience a mint and vanilla flavor combination, simply replace the second atomizer 600 with a new atomizer filled with vanilla-flavored e-liquid. This detachable design not only makes it convenient for users to change flavors but also facilitates cleaning and maintenance of the second atomizer 600, extending its lifespan. Furthermore, it allows for quick replacement in case of malfunction, ensuring the device's continued functionality. This structural design satisfies users' desire for diverse flavors while ensuring ease of use and maintenance.
[0035] Additionally, it's understandable that when the user needs to remove the second atomizer 600, the movable chamber 330 will move relative to the support 300. This movement causes the second air passage 332 at the top of the movable chamber 330 to misalign with the first air passage 320 at the top of the support 300, thus automatically sealing the first air passage 320. This design prevents air leakage in single-atomizer use mode. For example, when the user only wants to use the first atomizer 500, removing the second atomizer 600 from the movable chamber 330 will cause the movable chamber 330 to automatically move to a new position, causing the second air passage 332, which was originally connected to the first air passage 320, to be misaligned. This misalignment automatically seals the first air passage 320. Similar to the principle of a sliding door, when the second atomizer 600 is removed, the movable chamber 330 acts like a sliding baffle, automatically moving to the appropriate position to block the first airflow passage 320. This ensures that the first atomizer 500 will not leak air when used alone due to the removal of the second atomizer 600. This self-sealing design requires no additional operation from the user, ensuring both the safety of the device and the convenience of use, while also avoiding the waste of e-liquid and the decline in user experience caused by leakage.
[0036] In some embodiments, refer to Figure 7 A sealing element 400 is provided between the movable chamber 330 and the support 300. The sealing element 400 has a first sealing area 410 and a second sealing area 420. When the first air passage 320 is connected to the second air passage 332, the first sealing area 410 abuts against the movable chamber 330 and the support 300 respectively to seal the connection between the first air passage 320 and the second air passage 332. When the first air passage 320 and the second air passage 332 are misaligned, the second sealing area 420 abuts against the movable chamber 330 and the support 300 respectively to seal the misalignment between the first air passage 320 and the second air passage 332. Understandably, in this dual-atomization electronic cigarette, the sealing element 400 between the movable chamber 330 and the support 300 serves a double sealing function. The first sealing area 410 is responsible for sealing the connection between the first airway 320 and the second airway 332 in dual-atomization mode, ensuring that gas does not leak from the connection point when the two atomizers are operating. When the second atomizer 600 is removed and the system switches to single-atomization mode, the movable chamber 330 moves, causing the second airway 332 to be misaligned from the first airway 320. At this time, the second sealing area 420 will tightly abut against both the movable chamber 330 and the support 300, sealing the misaligned area and preventing gas leakage when the first atomizer 500 is operating.
[0037] Furthermore, the first sealing region 410 is arranged in a ring around the second air passage 332, and the second sealing region 420 surrounds the first sealing region 410. The inner diameter of the first sealing region 410 matches the outer diameter of the second air passage 332, and the inner edge of the second sealing region 420 is spaced apart from the outer edge of the first sealing region 410. It can be understood that the inner first sealing region 410 is arranged in a ring around the second air passage 332, and its inner diameter matches the outer diameter of the second air passage 332, allowing for a tight fit and seal. The outer second sealing region 420 surrounds the outer periphery of the first sealing region 410, and a gap is left between the edges of the two sealing regions, forming an independent sealing space. This design is like two concentric rings. When using the dual atomization mode, the inner ring seal ensures no air leakage at the connection between the two air passages, while when switching to the single atomization mode, the outer ring seal takes over to ensure the seal at the offset points.
[0038] In a dual-atomization e-cigarette system, the second atomizer 600 can be filled with various flavored e-liquids, such as mint, fruit, icy, or sweet.
[0039] In some embodiments, refer to Figure 1 , 37. A PCBA main board 700 is provided on the side of the bracket 300 away from the movable chamber. A conductive post 710 is provided on the PCBA main board 700, and the conductive post 710 protrudes into the movable chamber. A pin 610 is provided at the corresponding position of the second atomizer 600. When the second atomizer 600 is installed in the movable chamber, the conductive post 710 is electrically connected to the pin 610 to realize the control of the second atomizer 600 by the PCBA main board 700. Understandably, when a user wants to use a combination of mint and fruit flavors simultaneously, they insert the second atomizer 600, filled with fruit-flavored e-liquid, into the active chamber. At this point, pins 610 on the second atomizer 600 contact the conductive post 710, allowing the PCBA mainboard 700 to control the heating power and temperature of the second atomizer 600. This ensures the optimal balance between the fruit flavor and the mint flavor. This electrical connection design not only ensures the reliable implementation of the dual atomization function but also allows for precise control of the second atomizer 600 via the PCBA mainboard 700, providing a better flavor experience. During use, if the user finds the fruit flavor too weak, they can increase the output power of the second atomizer 600 using button 730. The light strip 720 will then increase in length, indicating that the power level has been increased. Conversely, if the fruit flavor is too strong, the user can decrease the power using button 730. The light strip 720 will then shorten in length, indicating that the power level has been decreased. This design allows users to precisely adjust the output power of the second atomizer 600 according to their personal taste preferences, while also intuitively understanding the current power setting status through the change in the light length of the LED strip 720, providing a better user interaction experience and personalized adjustment capabilities.
[0040] In some embodiments, refer to Figure 1 , 3 4. The movable chamber 330 has limiting protrusions 331 on both sides; the bracket 300 has limiting grooves 310 corresponding to the positions of the limiting protrusions 331; the movable chamber 330 can slide along the limiting grooves 310 to move the second air passage 332 relative to the first air passage 320. When the user wants to switch from dual-atomization mode (using both tobacco and mint flavors simultaneously) to single-atomization mode (using only tobacco flavor), simply push the movable chamber 330, and the limiting protrusions 331 will slide smoothly under the guidance of the limiting grooves 310, causing the second air passage 332 to be misaligned with the first air passage 320, thus achieving mode switching; conversely, when it is necessary to reactivate the dual-atomization mode, push the movable chamber 330 again, and the limiting protrusions 331 will slide in the opposite direction within the limiting grooves 310, reconnecting the two air passages. This limiting sliding structure not only ensures the smoothness and accuracy of the movement of the movable chamber 330, but also effectively prevents the movable chamber 330 from deviating or shaking.
[0041] In some embodiments, refer to Figure 4 The second atomizer 600 is embedded in the movable chamber, which has an inner locking groove 333. Correspondingly, the second atomizer 600 has an inner locking rib 620 that engages with the inner locking groove 333. Furthermore, the end of the second atomizer 600 furthest from the movable chamber has a locking protrusion 630 that protrudes from the movable chamber, allowing the second atomizer 600 to be pulled out by hand. When installing the second atomizer 600, the inner locking rib 620 automatically engages with the inner locking groove 333 in the movable chamber, producing a "click" sound, indicating proper installation. This inner locking structure ensures the stability of the second atomizer 600 during use, while the locking protrusion 630 greatly improves the convenience of atomizer replacement.
[0042] In some embodiments, refer to Figure 1 , 2 5. It also includes a second housing 200, which is fitted onto the first housing 100 and is rotatable relative to the first housing 100. The first housing 100 has a first window 110 and a second window 120, wherein the first window 110 corresponds to the setting position of the light strip 720 and is used to observe the light-emitting length of the light strip 720 to confirm the output power of the second atomizer 600, and the second window 120 corresponds to the position of the movable chamber 330 and is used for the assembly and disassembly of the second atomizer 600. The second housing 200 has a third window 210, and rotating the second housing 200 can align the third window 210 with the first window 110 and the second window 120 respectively, thereby selectively observing the light strip 720 or operating the second atomizer 600. Understandably, the outer second housing 200 can rotate freely relative to the inner first housing 100. The first housing 100 has two functional windows: the first window 110 is used to observe the light-emitting length of the LED strip 720 to determine the power level of the second atomizer 600, and the second window 120 is used for disassembling and assembling the second atomizer 600. The third window 210 on the second housing 200 can be rotated to align with these two windows respectively. For example, when the user wants to adjust the output power of the fruit-flavored atomizer, they can rotate the second housing 200 to align the third window 210 with the first window 110, at which point they can clearly observe the light-emitting length of the LED strip 720 to determine the current power level. When it is necessary to switch to a mint-flavored atomizer, simply continue to rotate the second housing 200 to align the third window 210 with the second window 120, and the atomizer can be easily disassembled and assembled through the window. This rotating window design not only achieves reasonable zoning of functional areas, but also allows the window to be covered by rotating the second housing 200 when not in use, improving the product's dustproof performance and aesthetics.
[0043] Furthermore, refer to Figure 6 The first housing 100 is provided with a first positioning part 130, and the second housing 200 is provided with a second positioning part 220. When the third window 210 is aligned with the first window 110 and the second window 120 respectively, the first positioning part 130 and the second positioning part 220 engage with each other, thereby achieving positioning of the second housing 200 in two positions. It can be understood that the two positioning parts will automatically engage when the third window 210 is aligned with the first window 110 or the second window 120, ensuring that the second housing 200 can accurately stop at the desired position.
[0044] Furthermore, the first positioning part 130 is a positioning protrusion, and the second positioning part 220 is a positioning groove that cooperates with the positioning protrusion; two positioning protrusions are arranged at intervals along the circumference of the first housing 100, and two positioning grooves are correspondingly arranged along the circumference of the second housing 200; the positioning protrusion has an arc-shaped raised surface, and the positioning groove has an arc-shaped groove surface that matches the raised surface. It can be understood that when the user wants to check the power display of the fruit-flavored atomizer, a noticeable sliding damping will be felt when rotating the second housing 200. When the third window 210 is rotated to the position of the first window 110, the arc-shaped raised surface of the positioning protrusion will naturally slide into the arc-shaped groove surface of the positioning groove and engage, not only can a clear "click" sound be heard, but a clear positioning feedback can also be felt; similarly, when it is necessary to replace the mint-flavored atomizer, continue to rotate the second housing 200, and another set of positioning protrusions and grooves will precisely engage when the third window 210 is aligned with the second window 120. The protrusions and grooves not only ensure accurate positioning, but also provide a smooth rotating feel through the arc transition, making the shell rotate both stably and smoothly.
