[0035] An electronic atomizing device is an electronic product that mimics the properties of a cigarette. It uses atomization and other methods to transform an aerosol-generating matrix into an aerosol that the user inhales, producing smoke, taste, and sensation similar to cigarettes.
[0036] In related technologies, with the development of electronic atomization devices, the atomization power of these devices has been continuously improved, resulting in a continuous increase in the maximum temperature of the aerosol output by these devices. Since different consumers have varying degrees of tolerance for aerosol temperature, excessively high aerosol temperatures can burn temperature-sensitive consumers, while excessively low temperatures can negatively impact the user experience for consumers with higher temperature requirements.
[0037] In view of the above problems, this application provides an electronic atomizing device, which aims to solve the technical problem of difficulty in adjusting the temperature of aerosols.
[0038] To illustrate the technical solution of this application, the following description is provided in conjunction with specific accompanying drawings and embodiments.
[0039] Please refer to Figure 1 , Figure 2 and Figure 3 This application provides an electronic atomizing device for heating an aerosol generating matrix to generate an aerosol. The electronic atomizing device includes a cup assembly 1, an atomizing assembly 2, and a mouthpiece assembly 3.
[0040] The cup assembly 1 has a liquid storage chamber 11 for storing the aerosol generation matrix. An atomizing assembly 2 is disposed in and communicates with the liquid storage chamber 11. The atomizing assembly 2 has an atomizing air passage 21, which heats the aerosol generation matrix entering the atomizing assembly 2 and generates aerosol within the atomizing air passage 21. The mouthpiece assembly 3 includes a mouthpiece 31 and a sliding tube 32 connected to and communicating with the mouthpiece 31. The sliding tube 32 is connected to the atomizing assembly 2 and communicates with the atomizing air passage 21 to form an outlet channel. The sliding tube 32 can reciprocate along the extension direction of the atomizing air passage 21, and the outlet channel is configured to lengthen as the mouthpiece 31 moves away from the atomizing assembly 2.
[0041] It should be noted that the aforementioned air outlet channel consists of the channel for transporting aerosols within the sliding tube 32 and the atomizing air channel 21. As the sliding tube 32 moves along the extension direction of the atomizing air channel 21, the length of the channel for transporting aerosols within the sliding tube 32 changes, thereby altering the length of the air outlet channel. Furthermore, when the nozzle 31 moves away from the atomizing component 2, the length of the channel for transporting aerosols within the sliding tube 32 increases, meaning the air outlet channel becomes longer.
[0042] Since the sliding tube 32 is connected to the atomizing component 2 and communicates with the atomizing air passage 21 to form an outlet channel, when the user inhales the electronic atomizing device of this embodiment, the atomizing component 2 heats the aerosol generation matrix to generate aerosol in the atomizing air passage 21. An airflow is generated in the electronic atomizing device, and the airflow carries the aerosol through the outlet channel and is output from the mouthpiece 31 and enters the user's mouth. The sliding tube 32, which encloses the outlet channel, can exchange heat with the aerosol to absorb some of the heat from the aerosol, thereby reducing the temperature of the aerosol output from the mouthpiece 31.
[0043] Please refer to Figure 2 In some embodiments, the nozzle 31 is located outside the cup assembly 1, and the sliding tube 32 is movably inserted through the cup assembly 1. As the sliding tube 32 moves, a portion of it protrudes from the cup assembly 1, allowing the portion outside the cup assembly 1 to contact the external space. It should be noted that the temperature of the external space of the electronic cup assembly 1 is lower than the temperature inside the atomizing airway 21. Therefore, the longer the sliding tube 32 outside the cup assembly 1, the longer the air outlet channel, the larger the contact area between the sliding tube 32 and the external space of the cup assembly 1, resulting in higher heat exchange efficiency between the sliding tube 32 and the aerosol, i.e., a lower temperature of the aerosol output from the nozzle 31. Conversely, the shorter the sliding tube 32 outside the cup assembly 1, the shorter the air outlet channel, the smaller the contact area between the sliding tube 32 and the external space of the cup assembly 1, resulting in lower heat exchange efficiency between the sliding tube 32 and the aerosol, i.e., a higher temperature of the aerosol output from the nozzle 31.
[0044] In the electronic atomizing device of this application embodiment, since the sliding tube 32 is connected to the atomizing component 2 and communicates with the atomizing air passage 21 to form an outlet channel, the outlet channel can transmit the aerosol generated by the atomizing core 22 heating the aerosol generation matrix. Furthermore, the sliding tube 32 surrounding the outlet channel can exchange heat with the aerosol to absorb some of the heat from the aerosol, thereby reducing the temperature of the aerosol output from the mouthpiece 31. Since the sliding tube 32 can reciprocate along the extension direction of the atomizing air passage 21, and the outlet channel is configured to lengthen as the mouthpiece 31 moves away from the atomizing component 2, the length of the outlet channel can be adjusted as the sliding tube 32 moves, thereby adjusting the length of the sliding tube 32 surrounding the outlet channel (adjusting the length of the sliding tube 32 located outside the cup assembly 1), and thus adjusting the temperature of the aerosol output from the mouthpiece 31.
[0045] Please refer to Figure 2 In some embodiments, the sliding tube 32 is sleeved on the outer periphery of a portion of the atomizing component 2 so that the sliding tube 32 is connected to the atomizing component 2 and communicates with the atomizing air passage 21.
[0046] Optionally, in some embodiments, the sliding tube 32 is inserted into the atomizing air passage 21 so that the sliding tube 32 is connected to the atomizing component 2 and communicates with the atomizing air passage 21.
[0047] Please refer to Figure 2 In some embodiments, the suction nozzle assembly 3 further includes a guide plate 33, which extends from the suction nozzle 31 and forms a cover cavity with the suction nozzle 31. The cover cavity is fitted onto the cup body assembly 1 and can slide relative to the cup body assembly 1.
[0048] In the above embodiment, the cup body assembly 1 is inserted into the mouthpiece assembly 3 through the cavity of the cover, and the guide plate 33 is sleeved on the outer periphery of the cup body assembly 1, making the electronic atomizing device more aesthetically pleasing and the structure more compact.
[0049] Furthermore, in the above embodiments, when the suction nozzle assembly 3 slides relative to the cup body assembly 1, the guide plate 33 can limit the position of the suction nozzle assembly 3 in a direction perpendicular to the sliding direction of the suction nozzle assembly 3. On the one hand, it can limit the sliding direction of the suction nozzle assembly 3, and on the other hand, it can prevent the suction nozzle assembly 3 from moving relative to the cup body assembly 1 in a direction perpendicular to the sliding direction of the suction nozzle assembly 3, so as to prevent the sliding tube 32 from breaking.
[0050] Please refer to Figure 2In some embodiments, the suction nozzle 31 includes a substrate 311 and a suction portion 312 connected to the substrate 311. The substrate 311 has a communicating hole 3111, the suction portion 312 is disposed on one side surface of the substrate 311 and communicates with the communicating hole 3111, and a sliding tube 32 is disposed on the side surface of the substrate 311 opposite to the suction portion 312 and communicates with the communicating hole 3111. The sliding tube 32 is received in the cover cavity.
[0051] In the above embodiment, the guide plate 33, nozzle 31, cup assembly 1, and sliding tube 32 enclose a heat exchange chamber 34. The air in the heat exchange chamber 34 exchanges heat with the aerosol through the sliding tube 32 and absorbs heat from the aerosol. When the nozzle 31 moves away from the atomizing assembly 2, the length of the sliding tube 32 outside the cup assembly 1 increases, and the volume of the heat exchange chamber 34 increases. The air in the heat exchange chamber 34 can absorb more heat from the aerosol, resulting in a greater range of lower temperatures for the aerosol output from the nozzle 31.
[0052] Please refer to Figure 2 In some embodiments, the substrate 311 is provided with a pressure relief hole 3112, which connects the cover cavity to the outside.
[0053] Understandably, the heat exchange chamber 34 is a sealed chamber. When the suction nozzle 31 moves away from the cup assembly 1, the heat exchange chamber 34 expands and its internal air pressure decreases. Under the influence of atmospheric pressure, the suction nozzle 31 will move closer to the cup assembly 1 until it returns to its initial position. Similarly, when the suction nozzle 31 moves closer to the cup assembly 1, the heat exchange chamber 34 shrinks and its internal air pressure increases. Under the influence of the air pressure inside the heat exchange chamber 34, the suction nozzle 31 will move away from the cup assembly 1 until it returns to its initial position. In other words, the pressure relief hole 3112 can balance the air pressure inside and outside the heat exchange chamber 34, making the heat exchange chamber 34 easy to fold.
[0054] In the above embodiment, the air inside the heat exchange chamber 34 can exchange with the outside through the pressure relief hole 3112. This allows cold air from the outside to enter the heat exchange chamber 34 through the pressure relief hole 3112, while hot air inside the heat exchange chamber 34 can be discharged through the pressure relief hole 3112. This allows the air inside the heat exchange chamber 34 to circulate rapidly, carrying away the heat from the sliding tube 32. As a result, the heat of the aerosol is rapidly reduced, and the temperature of the aerosol output from the nozzle 31 can drop rapidly.
[0055] Please refer to Figure 2 In some embodiments, two pressure relief holes 3112 are provided, and the two pressure relief holes 3112 are provided on opposite sides of the sliding tube 32.
[0056] The above configuration facilitates rapid air circulation within the heat exchange chamber 34, allowing the heat of the aerosol to be reduced quickly, and the temperature of the aerosol output from the nozzle 31 to drop rapidly.
[0057] In some embodiments, the guide plate 33 is provided with a pressure relief hole 3112, which connects the cover cavity to the outside.
[0058] Please refer to Figure 2 In some embodiments, the electronic atomizing device further includes a housing 4, in which a cup assembly 1 is housed and at least partially spaced from the inner wall of the housing 4. A sliding gap 41 is formed between the cup assembly 1 and the inner wall of the housing 4, and a guide plate 33 is inserted into the sliding gap 41.
[0059] In the above embodiments, the outer shell 4 can cover the overlap between the guide plate 33 and the shell assembly, making the electronic atomizing device more compact and aesthetically pleasing. Furthermore, the guide plate 33 is inserted into the sliding gap 41. When the mouthpiece assembly 3 slides, the outer shell 4 can limit the position of the guide plate 33 in a direction perpendicular to the sliding direction of the mouthpiece assembly 3. This limits the sliding direction of the mouthpiece assembly 3 and prevents the mouthpiece assembly 3 from moving relative to the cup assembly 1 in a direction perpendicular to the sliding direction of the mouthpiece assembly 3, thus preventing the sliding tube 32 from breaking.
[0060] Please refer to Figure 2 and Figure 3 In the sequential distribution direction of the cup body assembly 1, the guide plate 33 and the outer shell 4, the mouthpiece 31 protrudes from the guide plate 33 and is flush with the outer shell 4. When the mouthpiece assembly 3 slides relative to the cup body assembly 1 until the sliding tube 32 is completely inside the cup body assembly 1, the mouthpiece 31 fits and is flush with the outer shell 4, so that the electronic atomizing device is more compact and beautiful.
[0061] Please refer to Figures 4 to 6 In some embodiments, the guide plate 33 may also be fitted onto the housing 4 and be able to slide relative to the housing 4.
[0062] Please refer to Figure 2 In some embodiments, the cup assembly 1 includes a cup cylinder 12 and a first sealing member 13 and a second sealing member 14 disposed at both ends of the cup cylinder 12. The liquid storage chamber 11 is formed by the first sealing member 13 and the second sealing member 14. The first sealing member 13 is provided with a first insertion hole 131, and the second sealing member 14 is provided with a second insertion hole 141. Both the first insertion hole 131 and the second insertion hole 141 are connected to the atomizing air channel 21.
[0063] In the above embodiment, one end of the atomizing component 2 is inserted into the first insertion hole 131, the other end of the atomizing component 2 is inserted into the second insertion hole 141, and the sliding tube 32 is inserted into the first insertion hole 131, so that the sliding tube 32 is connected to the atomizing component 2 and communicates with the atomizing air passage 21.
[0064] This design makes the structure of each component of the cup assembly 1 relatively simple and the cost low, and also facilitates the assembly and disassembly of the cup assembly 1 and the atomizing assembly 2.
[0065] Please refer to Figure 7 In some embodiments, the atomizing assembly 2 includes an atomizing core 22, an air guide tube 23, and a mounting base 24. One end of the air guide tube 23 passes through a first insertion hole 131, and the end of the air guide tube 23 away from the first seal 13 communicates with the atomizing core 22. One end of the mounting base 24 passes through a second insertion hole 141, and the end of the mounting base 24 away from the second seal 14 communicates with the end of the atomizing core 22 away from the air guide tube 23. The air guide tube 23, the atomizing core 22, and the mounting base 24 are sequentially connected to form an atomizing air passage 21.
[0066] Please refer to the above as well. Figure 6 In the above embodiments, the sliding tube 32 is inserted into the first insertion hole 131, and the sliding tube 32 is inserted into the air guide tube 23, or the sliding tube 32 is sleeved on the outer periphery of the air guide tube 23.
[0067] When a user inhales the electronic atomizing device of this application embodiment, the airflow direction is: second insertion hole 141 → fixed base 24 → atomizing core 22 → air guide tube 23 → sliding tube 32 → connecting hole 3111 → inhalation part 312.
[0068] Please refer to Figure 7 In some embodiments, the atomizing core 22 includes a fixed cylinder 221, a liquid guiding component 222, and a heating mesh 223. One end of the fixed cylinder 221 is connected to the air guiding cylinder 23, and the other end of the fixed cylinder 221 is connected to the fixing base 24. The heating mesh 223 surrounds the inner wall of the fixed cylinder 221, and the liquid guiding component 222 is disposed between the inner wall of the fixed cylinder 221 and the heating mesh 223. The fixed cylinder 221 is provided with a liquid inlet hole 2211, and the liquid guiding component 222 contacts the aerosol generating matrix in the liquid storage chamber 11 through the liquid inlet hole 2211.
[0069] In the above embodiment, the liquid guide 222 contacts the aerosol generating matrix in the liquid storage chamber 11 through the liquid inlet 2211, and the heating mesh 223 contacts the aerosol generating matrix through the liquid guide 222. This not only controls the supply rate of the aerosol generating matrix, but also controls the contact area between the heating mesh 223 and the aerosol generating matrix. This ensures that when the aerosol generating matrix in the liquid storage chamber 11 decreases, the entire area of the heating mesh 223 can still contact the aerosol generating matrix through the liquid guide 222, thus preventing some heating mesh 223 from failing to contact the aerosol generating matrix and causing dry burning.
[0070] When a user inhales the electronic atomizing device according to this application embodiment, the airflow direction is: second insertion hole 141 → fixed base 24 → fixed cylinder 221 → air guide cylinder 23 → sliding tube 32 → connecting hole 3111 → suction part 312.
[0071] Please refer to Figure 2 In some embodiments, the electronic atomizing device further includes a power supply 5, which is electrically connected to the atomizing component 2.
[0072] The above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application, and should all be included within the protection scope of this application.
