Description

Technical Field

[0001] This application relates to the field of electronic cigarette technology, and in particular to an atomizing device. Background Technology

[0002] Heated tobacco products (HTMS) are atomizing devices that use electricity to heat a heating element, which in turn heats nicotine-containing tobacco and converts it into an inhalable aerosol. Specifically, outside air enters the e-cigarette through an air inlet and mixes with the vapor produced by the heated tobacco to form an aerosol.

[0003] In related technologies, to simplify the user's replacement operation, multiple cartridges can be set inside the electronic cigarette. After one cartridge is finished, the user can switch to another cartridge to continue smoking without having to refill the cartridge.

[0004] However, due to the poor sealing between the multiple cartridges in the aforementioned electronic cigarettes, the condensed smoke and moisture in the air can affect the unheated cartridges after the user inhales. Utility Model Content

[0005] Based on this, this application provides an atomizing device to solve the problem of insufficient sealing in atomizing devices in the related art.

[0006] This application provides an atomizing device for heating a collection of tobacco cartridges having multiple cartridge chambers. The atomizing device includes: a heating chamber, an air inlet, and an air outlet; a switching assembly including a first seal and a second seal, the first seal and the second seal being disposed in the heating chamber, and the collection of tobacco cartridges being disposed between the first seal and the second seal; the first seal having a first connecting port; the second seal having a second connecting port; the first connecting port communicating with the air outlet, and the second connecting port communicating with the air inlet; wherein the switching assembly is rotatable relative to the collection of tobacco cartridges, so that both the first connecting port and the second connecting port communicate with one of the cartridge chambers, and the first seal and the second seal respectively sealingly engage with the remaining cartridge chambers.

[0007] In one embodiment, the first seal includes a positioning shaft and a first sealing plate connected to each other, and the second seal includes a second sealing plate, a first communication port disposed on the first sealing plate, and a second communication port disposed on the second sealing plate; the positioning shaft passes through the collection cartridges and is positioned and engaged with the second sealing plate, and a plurality of cartridge cavities surround the outer periphery of the positioning shaft; the first sealing plate and the second sealing plate are respectively capable of sealing and engaging with the remaining cartridge cavities.

[0008] In one embodiment, one of the positioning shaft and the second sealing plate is provided with a positioning protrusion, and the other of the positioning shaft and the second sealing plate is provided with a positioning groove, with the positioning protrusion inserted into the positioning groove.

[0009] In one embodiment, the atomizing device further includes a first sealing plate and a second sealing plate; a first sealing member is sealed and fitted with the first sealing plate, and a second sealing member is sealed and fitted with the second sealing plate; the first sealing plate and the second sealing plate are respectively disposed at both ends of the heating chamber; the first sealing plate is provided with a plurality of first channels corresponding to a plurality of cartridge chambers and communicating tubes, and the second sealing plate is provided with a plurality of second channels corresponding to a plurality of cartridge chambers and communicating tubes; the switching component is rotatable relative to the assembled cartridges so that one of the first channels is connected to a first communicating port, and one of the second channels is connected to a second communicating port.

[0010] In one embodiment, the first sealing plate and the second sealing plate are each provided with a plurality of insertion slots on the opposite side, and the first sealing plate and the second sealing plate are respectively positioned and engaged with the collection cartridge through the corresponding insertion slots.

[0011] In one embodiment, the atomizing device further includes a housing and a nozzle. An air inlet is disposed in the housing, and a first sealing plate, a second sealing plate, a first sealing element, and a second sealing element are all disposed inside the housing. An air outlet is disposed in the nozzle, and the first sealing plate and the nozzle are connected to form an air outlet chamber. The first sealing element is rotatably disposed in the air outlet chamber, and the nozzle is limited to the housing.

[0012] In one embodiment, the atomizing device further includes a drive member disposed within the housing, the drive member being drivenly connected to one of a first seal and a second seal, so that the switching assembly can rotate relative to the collection cartridge.

[0013] In one embodiment, a drive bracket is provided inside the housing, and the drive bracket fits against the inner wall of the housing. The drive member and the second seal are located on both sides of the drive bracket, respectively. The drive bracket is provided with a clearance hole. The side of the second seal away from the first seal is provided with a connecting shaft and a sealing protrusion. The sealing protrusion surrounds the outer periphery of the connecting shaft and abuts against the drive bracket. The connecting shaft passes through the clearance hole and connects to the drive member.

[0014] In one embodiment, one of the nozzle and the housing is provided with a limiting groove, and the other of the nozzle and the housing is provided with a limiting post, with the limiting groove and the limiting post engaging in a limiting fit.

Furthermore, the first and second seals can respectively seal and engage with the remaining cartridge chambers. This allows airflow within one cartridge chamber through the air inlet, the first connecting port, and the second connecting port, enabling the smoke generated by the heated cartridge to be inhaled by the user through the air outlet. Simultaneously, since there is no airflow in the remaining cartridge chambers, the airflow or aroma within those chambers cannot be inhaled by the user. Moreover, after the user finishes inhaling, because the remaining cartridge chambers are sealed, condensed smoke and moisture from the air will not enter the remaining cartridge chambers, thus not affecting the unheated cartridges.

[0037] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0038] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or state relationship based on the orientation or state relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0039] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0040] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly.

[0042] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0043] See Figure 1 and Figure 12 , Figure 1 A cross-sectional view of the atomizing device provided in an embodiment of this application is shown. Figure 12 An exploded view of an atomizing device provided in an embodiment of this application is shown. One embodiment of this application provides an atomizing device for heating a collection of tobacco cartridges having multiple cartridge chambers. The atomizing device includes a heating chamber, an air inlet 33, an air outlet, and a switching assembly 20. The switching assembly 20 includes a first seal 21 and a second seal 22, which are disposed in the heating chamber. The collection of tobacco cartridges 10 is disposed between the first seal 21 and the second seal 22. The first seal 21 has a first connecting port 211. The second seal 22 has a second connecting port 221. The first connecting port 211 communicates with the air outlet, and the second connecting port 221 communicates with the air inlet 33. The switching assembly 20 is rotatable relative to the collection of tobacco cartridges 10, so that both the first connecting port 211 and the second connecting port 221 communicate with one of the cartridge chambers 11, and the first seal 21 and the second seal 22 respectively seal against the remaining cartridge chambers 11.

[0044] By applying the technical solution of this application, the switching component 20 is rotated relative to the collection of cartridges 10, so that the first connecting port 211 of the first sealing member 21 is connected to one of the multiple cartridge chambers 11, and the second connecting port 221 of the second sealing member 22 is connected to one of the multiple cartridge chambers 11. Furthermore, the first sealing member 21 and the second sealing member 22 can respectively seal and cooperate with the remaining cartridge chambers 11. Thus, airflow can be achieved in one of the cartridge chambers 11 through the air inlet 33, the first connecting port 211 and the second connecting port 221, so that the smoke generated by the heated cartridge 1 can be inhaled by the user through the air outlet. At the same time, since there is no airflow in the other cartridge chambers 11, the airflow or odor in the other cartridge chambers 11 cannot be inhaled by the user, thus preventing the odor or off-flavor of the heated cartridge from mixing into the aerosol generated by the heated cartridge 1. Furthermore, during and after a user inhales a certain cartridge 1, since the remaining cartridge chambers 11 are sealed, the condensed smoke and moisture in the air will not enter the remaining cartridge chambers 11, and will not affect the unheated cartridge 1.

[0045] Multiple cartridge chambers 11 are arranged sequentially along the circumference. Each cartridge chamber 11 can hold one cartridge 1. The number of cartridges 1 is determined by the number of cartridge chambers 11. The cartridge 10 of this application is used for storing and replacing cartridges 1. During the user's inhalation, in order to facilitate smooth airflow, one or more axially penetrating vents can be provided in the inner and / or outer peripheral sidewalls of the cartridge 1 to ensure that the aerosol generation matrix is ​​better carbonized, thereby improving the atomization efficiency of the cartridge 1. It can also reduce the user's inhalation force and improve the user experience.

[0046] In some embodiments, the cartridge 1 is made of tobacco material, preferably a solid or integrally molded tobacco extract or a nicotine-containing substance, and the number of such cartridges is greater than or equal to two. Of course, the cartridge 1 can also be filled with filamentous, granular, or sheet-like material, and leakage of such material is prevented by sealing both ends of the cartridge 1.

[0047] It should be noted that the switching component 20 can rotate relative to the collection cartridge 10, including the following situations: the switching component 20 rotates while the collection cartridge 10 remains stationary; or, the switching component 20 remains stationary while the collection cartridge 10 rotates; or, both the switching component 20 and the collection cartridge 10 rotate. As long as relative rotation between the two can be achieved, it is acceptable.

[0048] In some embodiments, a heating element is disposed on the cavity wall of the heating chamber. The heating element is located outside the collection of tobacco cartridges and includes multiple heating films. Each heating film can independently heat its corresponding tobacco cartridge 1 from the outside.

[0049] Figure 2 An exploded view of the collection of smoke cartridges and switching components provided in an embodiment of this application is shown. Figure 8 A schematic diagram of the structure of the first sealing element provided in an embodiment of this application is shown. Figure 9 A schematic diagram of the structure of the second seal provided in an embodiment of this application is shown. (In conjunction with...) Figure 2 , Figure 8 as well as Figure 9As shown, the first sealing element 21 includes a positioning shaft 212 and a first sealing plate 213 connected to each other, and the second sealing element 22 includes a second sealing plate 222. A first connecting port 211 is disposed on the first sealing plate 213, and a second connecting port 221 is disposed on the second sealing plate 222. The positioning shaft 212 passes through the cartridge 10 and is positioned and engaged with the second sealing plate 222. Multiple cartridge cavities 11 surround the outer periphery of the positioning shaft 212. The first sealing plate 213 and the second sealing plate 222 can respectively seal and engage with the remaining cartridge cavities 11. With the above design, the positioning and engagement of the positioning shaft 212 and the second sealing plate 222 allows the first sealing plate 213 to rotate simultaneously with the second sealing plate 222, thereby simultaneously sealing the remaining cartridge cavities 11, so that the remaining cartridge cavities 11 have a good sealing effect.

[0050] In some embodiments, in order to enhance the sealing performance of the first seal 21 and the second seal 22, both the first sealing plate 213 and the second sealing plate 222 may be made of silicone material.

[0051] Combination Figure 8 and Figure 9 As shown, one of the positioning shaft 212 and the second sealing plate 222 is provided with a positioning protrusion 2221, and the other of the positioning shaft 212 and the second sealing plate 222 is provided with a positioning groove 2121. The positioning protrusion 2221 is inserted into the positioning groove 2121. The above-mentioned matching structure of the positioning protrusion 2221 and the positioning groove 2121 is simple in structure and easy to process.

[0052] In some embodiments, both the positioning protrusion 2221 and the positioning groove 2121 adopt a cross-shaped structure to achieve a good positioning effect.

Figure 4 An exploded view of the combination of a cigarette cartridge and a mouthpiece provided in an embodiment of this application is shown. Figure 5 An assembly diagram of the suction nozzle, first sealing plate, and first sealing element provided in an embodiment of this application is shown. Figure 6 An assembly diagram of the mouthpiece and the cartridge provided in an embodiment of this application is shown. Figure 7 An exploded view of a collection of smoke bombs provided in an embodiment of this application is shown. (Combined with...) Figures 3 to 7As shown, the atomizing device includes a first sealing plate 12 and a second sealing plate 13. A first sealing member 21 is sealed and fitted with the first sealing plate 12, and a second sealing member 22 is sealed and fitted with the second sealing plate 13. The first sealing plate 12 and the second sealing plate 13 are respectively disposed at both ends of the heating chamber and located on both sides of the cartridge 10 to seal multiple cartridge chambers 11. The first sealing plate 12 is provided with multiple first channels 121 corresponding to the multiple cartridge chambers 11, and the second sealing plate 13 is provided with multiple second channels 131 corresponding to the multiple cartridge chambers 11. The switching component 20 can rotate relative to the cartridge 10 so that one of the first channels 121 is connected to the first connecting port 211, and one of the second channels 131 is connected to the second connecting port 221. With the above design, the first sealing plate 12 and the second sealing plate 13 can seal the cartridge, isolating the multiple cartridge chambers 11 from each other, thereby preventing the condensed smoke and moisture from flowing between the cartridge chambers 11.

[0054] In some embodiments, a good sealing effect can be formed by the first sealing plate 213 and the first sealing plate 12 being bonded together, and the second sealing plate 222 and the second sealing plate 13 being bonded together.

[0055] Combination Figure 7 As shown, in some embodiments, the cartridge 10 includes a cartridge shell 15, a cartridge inner shell 16, and a plurality of partition plates 14. The cartridge shell 15 is located on the outer periphery of the cartridge inner shell 16. The plurality of partition plates 14 are spaced apart along the circumference of the cartridge inner shell 16 between the cartridge shell 15 and the cartridge inner shell 16, and respectively abut against the inner wall of the cartridge shell 15 and the outer wall of the cartridge inner shell 16, thereby dividing the space between the cartridge shell 15 and the cartridge inner shell 16 into a plurality of cartridge cavities 11.

[0056] By using the cartridge shell 15 to fit around the outer periphery of the partition plate 14, the cartridge shell 15 and the outer side of the partition plate 14 form a sealed fit, which can separate multiple cartridges 1 from the outside of the cartridge 1, thereby preventing condensed smoke and moisture from flowing between the cartridge chambers 11.

[0057] By using the inner shell 16 of the cartridge to be disposed inside the multiple partition plates 14, the inner shell 16 of the cartridge and the inner side of the partition plates 14 form a sealed fit, which can separate the multiple cartridges 1 from the inside of the cartridge 1, thereby preventing the condensed smoke and moisture from flowing between the cartridge chambers 11.

[0058] In some embodiments, a first sealing plate 12 covers one side of the cartridge shell 15 and the cartridge inner shell 16, and a second sealing plate 13 covers the other side of the cartridge shell 15 and the cartridge inner shell 16. The two ends of each partition plate 14 are respectively attached to the first sealing plate 12 and the second sealing plate 13 to form a plurality of mutually separated cartridge cavities 11.

[0059] The partition plate 14 is used to separate each cartridge 1, so that each cartridge cavity 11 is independent. The partition plate 14 can be made of a low thermal conductivity material such as fiber paper.

[0060] The inner shell 16 and outer shell 15 of the cartridge can be made of ordinary cigarette paper or cellulose, or they can be made of high thermal conductivity materials such as metal.

[0061] In some embodiments, the separator has a heat-insulating cavity. The heat-insulating cavity provides insulation, preventing heat from being transferred through the separator to adjacent cartridges 1 when one cartridge 1 is heated, thereby preventing heat transfer between cartridges 1.

[0062] In other embodiments, the separator comprises a solid sheet. By selecting a material with low thermal conductivity, the solid sheet separator can also isolate heat, preventing heat from being transferred through the separator to adjacent cartridges 1 when one cartridge 1 is heated, thereby preventing heat transfer between cartridges 1.

[0063] The inner shell 16 of the cartridge allows air vents to be formed on the inside of the cartridge 1, which allows airflow to be smooth and also allows the heating element to be placed on the inside of the cartridge 1, so that each cartridge 1 has a corresponding heating film, and each heating film can independently heat the cartridge 1 it corresponds to.

[0064] Of course, the inner heating element and the outer heating element can be selected separately or both can be set. It is preferable to set the outer heating element.

[0065] Figure 10 A schematic diagram of the structure of the first sealing plate provided in an embodiment of this application is shown. Figure 11 A schematic diagram of the structure of the second sealing plate provided in an embodiment of this application is shown. (In conjunction with...) Figure 10 and Figure 11 As shown, the first sealing plate 12 and the second sealing plate 13 are each provided with multiple insertion slots 17 on their opposite sides. The first sealing plate 12 and the second sealing plate 13 are respectively positioned and engaged with the collection cartridge 10 through the corresponding insertion slots 17. With the above design, the first sealing plate 12 and the second sealing plate 13 can be prevented from rotating relative to the collection cartridge 10, thereby preventing the sealing of the first sealing plate 12 and the second sealing plate 13 from failing.

[0066] In some embodiments, the two ends of the partition plate extend beyond the cartridge cavity and form limiting protrusions. The limiting protrusions at both ends of each partition plate 14 are respectively inserted into the insertion slots 17 of the first sealing plate 12 and the second sealing plate 13. With the above design, by inserting the partition plate 14 into the insertion slots 17, the partition plate 14 can be well fixed with the first sealing plate 12 and the second sealing plate 13.

[0067] When the insertion groove 17 and the corresponding limiting protrusion extend radially to the cartridge shell 15, the sealing performance of the cartridge cavity 11 can be further enhanced.

[0068] Combination Figure 1 and Figure 12 As shown, the atomizing device also includes a housing 30 and a mouthpiece 40. An air inlet 33 is disposed within the housing 30, and the first sealing plate 12, the second sealing plate 13, the first sealing element 21, and the second sealing element 22 are all disposed within the housing 30. An air outlet is disposed within the mouthpiece 40. The first sealing plate 12 and the mouthpiece 40 are connected and form an air outlet chamber. The first sealing element 21 is rotatably disposed within the air outlet chamber, and the mouthpiece 40 is positioned within the housing 30. By integrating the mouthpiece 40, the first sealing plate 12, and the first sealing element 21 into a single unit, users only need to perform one disassembly and assembly operation when replacing the cartridge 10, simplifying the operation process.

[0069] Outside air enters the housing 30 through the air inlet 33, and then enters the cartridge chamber 11 of the cartridge 10 through the second connecting port 221. The smoke generated by the heated cartridge 1 mixes with the air to form an aerosol, which is then inhaled by the user through the first connecting port 211 and the mouthpiece 40.

[0070] In some embodiments, the first sealing plate 12 and the suction nozzle 40 are connected by an interference fit. As the first sealing plate 213 rotates, the first channel 121 can communicate with the suction nozzle 40 through the first connecting port 211.

[0071] Furthermore, the cartridge chamber 11 formed by the division of two adjacent partition plates can connect the cartridge 1 to the mouthpiece 40, so that each cartridge 1 can be aligned with the corresponding heating element of the atomizing device.

[0072] Combination Figure 1 As shown, the atomizing device also includes a drive component 50, which is disposed within the housing 30. The drive component 50 is drivenly connected to one of the first seal 21 and the second seal 22, enabling the switching assembly 20 to rotate relative to the cartridge 10. The drive component 50 drives the first seal 21 and the second seal 22 to rotate, allowing the first connecting port 211 and the second connecting port 221 to connect with the corresponding cartridge cavity 11, thereby allowing air to flow into the cartridge cavity 11. After one cartridge 1 has finished heating, rotation can be used to connect the first connecting port 211 and the second connecting port 221 with the corresponding cartridge cavity 11.

[0073] Combination Figure 1As shown, a drive bracket 31 is provided inside the housing 30, and the drive bracket 31 is in contact with the inner wall of the housing 30. The drive component 50 and the second sealing component 22 are located on both sides of the drive bracket 31, respectively. The drive bracket 31 is provided with a clearance hole. On the side of the second sealing component 22 away from the first sealing component 21, a connecting shaft 223 and a sealing protrusion 224 are provided. The sealing protrusion 224 surrounds the outer periphery of the connecting shaft 223 and abuts against the drive bracket 31. The connecting shaft 223 passes through the clearance hole and connects to the drive component 50. With the above design, the drive bracket 31 can isolate the drive component 50 from the collection cartridge 10, and the sealing protrusion 224 can isolate the air inlet 33, the first connecting port 211 and the clearance hole, thereby preventing condensed smoke and moisture in the air from damaging the drive component 50.

[0074] The second connecting port 221 is located outside the sealing protrusion 224, and the air inlet 33 and the second connecting port 221 are connected through the space enclosed by the sealing protrusion 224 and the inner wall of the housing 30.

[0075] Furthermore, by abutting the sealing protrusion 224 against the drive bracket 31, the second sealing plate 222 can always be in contact with the second sealing plate 13, thereby avoiding sealing failure.

[0076] Combination Figure 12 As shown, one of the mouthpiece 40 and the housing 30 is provided with a limiting groove 32, and the other of the mouthpiece 40 and the housing 30 is provided with a limiting post 41. The limiting groove 32 and the limiting post 41 are in a limiting fit. By adopting the above-mentioned limiting fit, the cartridge 10 can be accurately positioned so that the cartridge 1 can be accurately positioned with the heating element.

[0077] Figure 13 A schematic diagram of the suction nozzle provided in an embodiment of this application is shown. (In conjunction with...) Figure 13 As shown, the mouthpiece 40 has an elastic arm 42 facing the first seal 21. The elastic arm 42 abuts against the first seal 21 to ensure a sealing fit between the first seal 21 and the remaining cartridge chambers 11. The elastic arm 42 provides pressure to the first seal 21, ensuring that the first seal 21 remains in a sealed fit with the cartridge chambers 11 and preventing seal failure.

[0078] Multiple elastic arms 42 can be arranged circumferentially, and each elastic arm 42 is respectively attached to the first sealing plate 213, so that the first sealing plate 213 is always attached to the first sealing plate 12, thereby avoiding sealing failure.

[0079] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0080] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
