Description

Technical Field

[0001] Embodiments of the present disclosure generally relate to the technical field of atomization devices, and more specifically, to an atomizer of an electronic atomization device and an electronic atomization device including the atomizer. Background Art

[0002] Conventional electronic atomization devices are mainly composed of an atomizer and a power supply component for powering the atomizer. The atomizer generally includes an atomizing component and a liquid storage tank connected to the atomizing component, and the liquid storage tank stores the atomizing medium. When the atomizing component is powered, the atomizing core in the atomizing component can atomize the atomizing medium flowing from the liquid storage tank to the atomizing core to generate an aerosol for inhalation.

[0003] The air inlet and outlet of a conventional atomizer form an air flow channel, and the atomizer core is arranged in the air flow channel. The air flow channel between the atomizer core and the air outlet passes through the liquid storage tank, causing the heated aerosol and the atomizing medium in the liquid storage tank to interact with each other. On the one hand, the atomizing medium in the liquid storage tank will cool down the aerosol and reduce the temperature of the aerosol. At the same time, the reduction in the temperature of the aerosol is easy to condense in the air flow channel to form condensate, affecting the user experience; on the other hand, the aerosol will heat up the atomizing medium in the liquid storage tank, thereby affecting the quality of the atomizing medium. Summary of the invention

[0006] According to the embodiments of the present disclosure, since the air outlet channel is located between the air outlet side of the atomizer core and the outlet of the air flow channel, and the air outlet channel is separated from the liquid storage tank, the contact path length of the aerosol released from the air outlet side of the atomizer core and the liquid storage tank is significantly reduced, thereby weakening the mutual influence between the aerosol and the atomizing medium in the liquid storage tank.

[0007] To sum up, on the one hand, the liquid atomizing medium in the liquid storage tank will not significantly cool down the aerosol, thereby not significantly reducing the inlet temperature of the aerosol; at the same time, the aerosol temperature will not significantly decrease, thereby not condensing in the air flow channel to form a large amount of condensate, which will not affect the user experience; on the other hand, the aerosol will not cause the liquid atomizing medium in the liquid storage tank to significantly heat up, thereby not significantly affecting the quality of the atomizing medium.

[0040] As described above, the airflow channel between the atomizer core and the air outlet passes through the liquid storage tank, causing the heated aerosol to interact with the liquid atomizing medium in the liquid storage tank. The embodiment of the present disclosure provides an electronic atomization device 100 to solve the problem that the airflow channel in conventional electronic atomization devices passes through the liquid storage tank. Figures 1 to 13 The principles of the present disclosure are described.

[0041] Figure 1 A schematic structural diagram of an electronic atomization device 100 according to some embodiments of the present disclosure is shown. Figure 2 Shows Figure 1 FIG. 1 is an exploded view of the electronic atomization device 100. Figure 1 to Figure 2 As shown, the electronic atomization device 100 described herein generally includes an atomizer 10 and a power supply assembly 20, and the power supply assembly 20 is electrically connected to the atomizer 10 to provide the working voltage required for the atomizer 10 to work. The atomizer 10 includes an atomization assembly 3 and a first shell 1, the atomization assembly 3 is arranged inside the first shell 1, and a liquid storage tank 11 is also arranged inside the first shell 1, wherein the liquid storage tank 11 can store atomized medium. A suction nozzle 12 for suction is also provided on the outer side of the first shell 1. The atomization assembly 3 is connected to the liquid storage tank 11, so that the atomized medium is atomized and an aerosol is generated. Atomization methods include heating atomization and ultrasonic atomization, etc., which are not limited to the embodiments of the present disclosure.

[0042] In some embodiments, Figure 1 to Figure 2 As shown, the atomizer 10 can be arranged up and down with the power supply assembly 20. In other embodiments, the atomizer 10 can also be arranged left and right with the power supply assembly 20.

[0043] Continue reading Figure 1 to Figure 2In some embodiments, the liquid storage tank 11 and the atomizing assembly 3 can be arranged along the axial direction of the atomizer 10, and the liquid storage tank 11 and the atomizing assembly 3 are arranged up and down, that is, the liquid storage tank is arranged above the atomizing assembly. In other embodiments, the liquid storage tank 11 and the atomizing assembly 3 can also be arranged along the gas outlet direction of the outlet 231, and the atomizing assembly 3 is arranged adjacent to the suction nozzle 12, that is, the liquid storage tank 11 and the atomizing assembly 3 are arranged left and right. In other embodiments, part of the atomizing assembly 3 can also be arranged inside the liquid storage tank 11. In the following, in the case where the atomizer 10 and the power supply assembly 20 are arranged up and down, the principle of the present disclosure will be mainly described based on the situation that the liquid storage tank 11, the atomizing assembly 3 and the power supply assembly 20 are arranged up and down in sequence, and the situation that part of the atomizing assembly 3 is arranged inside the liquid storage tank 11. The situation of other arrangements of the liquid storage tank 11, the atomizing assembly 3 and the power supply assembly 20 is also similar, and will not be repeated in the following.

[0044] Figure 3 A cross-sectional view of an electronic atomization device 100 according to some embodiments of the present disclosure is shown. Figure 4 Shown according to Figure 3 A partially enlarged cross-sectional view of the electronic atomization device 100 is shown. Figure 5 A partial cross-sectional view of an electronic atomization device 100 according to some other embodiments of the present disclosure is shown. Figure 6 A partial cross-sectional view of an electronic atomization device 100 according to some further embodiments of the present disclosure is shown. Figure 7 FIG. 1 shows a partial cross-sectional view of an electronic atomization device 100 according to some further embodiments of the present disclosure. Figures 3 to 6 As shown, the liquid storage tank 11, the atomization assembly 3 and the power supply assembly 20 are arranged in sequence up and down. Figure 7 As shown, part of the atomization assembly 3 is disposed inside the liquid storage tank 11 , and the liquid storage tank 11 and the power supply assembly 20 are arranged up and down.

[0045] Obviously, Figures 3 to 7 The liquid storage tank 11 shown is arranged inside the end of the first housing 1 away from the power supply assembly 20. The liquid storage tank 11 is mainly used to store liquid atomization medium, wherein Figures 3 to 6 The liquid storage tank 11 shown in the figure directly stores the liquid atomizing medium. Figure 7 The liquid storage tank 11 shown in the figure stores the liquid atomizing medium through the liquid storage cotton. Figures 3 to 6 The liquid storage tank 11 shown can also store liquid atomization medium through liquid storage cotton. Figure 7The liquid storage tank 11 shown can also directly store liquid atomizing medium. It should be noted that the atomizing core may include a liquid-conducting liquid and a heating element, and the heating element is arranged on the liquid-conducting liquid, which can atomize the atomizing medium conducted by the heating element. The liquid-conducting liquid may include a plurality of gaps or orifices extending from a first side of the liquid-conducting liquid to a second side, and the fluid may pass through these gaps or orifices, for example, it may be a liquid-absorbing material such as ceramics and cotton. The heating element may be a metal heating wire, a heating net or a heating film, etc., which generates heat after being powered on to atomize the atomizing medium conducted by the liquid-conducting liquid.

[0046] Continue reading Figures 3 to 7 , an air flow channel 2 is provided in the atomizer 10, and the atomizing core 32 of the atomizing assembly 3 participates in forming the air flow channel 2. The first inlet 211 of the air flow channel 2 is configured to allow gas to enter the atomizer 10, and the outlet 231 is configured to allow the aerosol formed by the atomizing medium to flow out of the atomizer 10. The air flow channel 2 includes an air outlet channel 23. The air outlet channel 23 is located between the air outlet side 321 of the atomizing core 32 and the outlet 231 of the air flow channel 2, wherein the outlet 231 of the air outlet channel 23 is the outlet 231 of the air flow channel 2. The aerosol generated by the atomizing medium after atomization is released outward through the air outlet side 321 of the atomizing core 32.

[0047] It should be noted that the air outlet side 321 of the atomizer core 32 is the side where the aerosol is released from the atomizer core 32. For example, in some embodiments, see Figures 3 to 6 The air outlet side 321 is the surface of the atomizer core 32 that generates aerosol, specifically the bottom surface of the atomizer core 32. In other embodiments, it can also be the side surface or top surface of the atomizer core. Figure 7 In this embodiment, the gas outlet side 321 is the surface of the atomizer core 32 for aerosol to flow out. In this embodiment, the gas outlet side 321 is specifically the lower surface of the atomizer core 32. Figures 3 to 6 In the description, the structure and principle of the atomizer will be mainly described with the bottom surface of the ceramic atomization core as the gas outlet side 321.

[0048] In some embodiments, the air outlet channel 23 is separated from the liquid storage tank 11. Specifically, at least half of the air outlet channel 23 is separated from the liquid storage tank 11. Therefore, the contact path length between the aerosol released from the air outlet side 321 of the atomization core 32 and the liquid storage tank 11 is significantly reduced.

[0049] It should be noted that separation refers to separating the air outlet channel 23 from the liquid storage tank 11, so that the aerosol in the air outlet channel 23 does not contact the outer wall of the liquid storage tank 11, so that the aerosol in the air outlet channel 23 does not interact with the atomized medium in the liquid storage tank 11. In addition, the numbers, values, numbers, etc. mentioned above and elsewhere in this disclosure are exemplary and are not intended to limit the scope of this disclosure in any way. Any other appropriate numbers, values, and numbers are possible. Depending on the specific application scenario and requirements, more parts of the air outlet channel 23 can be separated from the liquid storage tank 11, for example, 4 / 5 of the air outlet channel 23 is separated from the liquid storage tank 11. Obviously, the more parts of the air outlet channel 23 are separated from the liquid storage tank 11, the less mutual influence between the aerosol and the atomized medium in the liquid storage tank 11.

[0050] According to the embodiment of the present disclosure, since the air outlet channel 23 is located between the air outlet side 321 of the atomizer core 32 and the outlet 231 of the air flow channel 2, and the air outlet channel 23 is separated from the liquid storage tank 11, the contact path length between the aerosol released from the air outlet side 321 of the atomizer core 32 and the liquid storage tank 11 is significantly reduced, thereby weakening the mutual influence between the aerosol and the atomizing medium in the liquid storage tank 11. With the above configuration, on the one hand, the liquid atomizing medium in the liquid storage tank 11 will not significantly cool the aerosol, thereby not significantly reducing the inlet temperature of the aerosol; at the same time, the temperature of the aerosol will not significantly decrease, thereby not condensing in the air flow channel 2 to form a large amount of condensate, which will not affect the user experience; on the other hand, the aerosol will not cause the liquid atomizing medium in the liquid storage tank 11 to significantly heat up, thereby not significantly affecting the quality of the atomizing medium.

[0051] Obviously, if the gas outlet channel 23 is completely separated from the liquid storage tank 11 , the aerosol in the gas outlet channel 23 and the liquid atomized medium in the liquid storage tank 11 will not affect each other.

[0052] Continue reading Figures 3 to 7 The atomizer 10 further includes a mounting chamber 101 for accommodating the atomizer core 32. The air flow channel 2 includes a first air inlet channel 21, and the first air inlet channel 21 extends from the first inlet 211 to the inner wall of the mounting chamber 101. Figures 3 to 6 In some embodiments, the first air inlet channel 21 is separated from the liquid storage tank 11. Figure 7 In some embodiments, the first air inlet channel 21 passes through the liquid storage tank 11. It can be understood that since air rather than aerosol flows in the first air inlet channel 21, when the first air inlet channel 21 passes through the liquid storage tank 11, the gas in the first air inlet channel 21 will not affect the atomized medium in the liquid storage tank 11.

[0053] Continue reading Figures 3 to 7, the air flow channel 2 further includes a second air inlet channel 22. The second air inlet channel 22 is disposed between the first air inlet channel 21 and the air outlet channel 23, and the second air inlet channel 22 is communicated with the first air inlet channel 21 and the air outlet channel 23. Specifically, the second air inlet channel 22 includes a second inlet 221 located at the inner wall of the installation chamber 101, and the second air inlet channel 22 extends from the second inlet 221 to the air outlet side 321 of the atomizer core 32.

[0054] Continue reading Figures 3 to 6 In some embodiments, the first air inlet channel 21 is disposed at the bottom of the atomizer assembly 3, and the gas in the second inlet 221 of the second air inlet channel 22 is blown toward the bottom of the atomizer core 32. Figure 7 In other embodiments, the first air inlet channel 21 is disposed at the top of the atomizer assembly 3, and the gas in the second inlet 221 of the second air inlet channel 22 is blown toward the top of the atomizer core 32. In still other embodiments, the first air inlet channel 21 may also be disposed at the side of the atomizer assembly 3, and the gas in the second inlet 221 of the second air inlet channel 22 is blown toward the side of the atomizer core 32.

[0055] See also Figures 5 to 7 In some embodiments, along the air inlet direction of the second air inlet channel 22, the projection of the second inlet 221 of the second air inlet channel 22 at least partially overlaps with the projection of the air outlet side 321 of the atomizer core 32. That is, the second inlet 221 of the second air inlet channel 22 is at least partially aligned with the air outlet side 321 of the atomizer core 32, so that the gas can fully bring the aerosol out from the outlet 231. Figure 3 to Figure 4 In other embodiments, along the air inlet direction of the second air inlet channel 22, the projection of the second inlet 221 of the second air inlet channel 22 is staggered from the projection of the air outlet side 321 of the atomizer core 32, and the projection 221 of the second inlet 221 of the second air inlet channel 22 is farther away from the projection of the outlet 231 relative to the projection of the air outlet side 321 of the atomizer core 32. That is, along the air inlet direction of the second air inlet channel 22, the projection of the air outlet side 321 of the atomizer core 32 is located between the projections of the second inlet 221 and the outlet 231 of the second air inlet channel 22, so the gas can also fully bring the aerosol out of the outlet 231.

[0056] Return to Reference Figures 1 to 7In some embodiments, the suction nozzle 12 is disposed on the outer side of the first shell 1 and extends outward. With the above configuration, when the user is standing upright or lying down to inhale, since the suction nozzle 12 is on the outer side of the first shell 1, the liquid storage tank 11 will basically not face downward, thereby ensuring that the liquid atomization medium in the liquid storage tank 11 can enter the atomization core 32, thereby preventing the atomization core 32 from burning dry. In addition, since at least half of the air outlet channel 23 is separated from the liquid storage tank 11, and the suction nozzle 12 is disposed on the outer side of the first shell 1, the air flow channel 2 can not completely pass through the liquid storage tank 11. Therefore, when the size of the liquid storage tank 11 along the air inlet direction of the second air inlet channel 22 is increased, the part of the air outlet channel 23 will not be affected by the increase in the size of the liquid storage tank 11, thereby achieving the purpose of large liquid storage and short channel, and solving the problem that the length of the air flow channel 2 cannot be shortened because the air flow channel 2 completely passes through the liquid storage tank 11 when the size of the liquid storage tank 11 along the air inlet direction of the second air inlet channel 22 is increased.

[0057] In the above embodiment, the suction nozzle 12 is provided on the outer side of the first housing 1, and the user can suck out the aerosol by holding the suction nozzle 12. In other embodiments, the outer side of the first housing 1 may also have no suction nozzle 12, but only the outlet 231 of the air outlet channel 23, and an exhaust structure (not shown in the figure) for exhausting aerosol is provided inside the electronic atomization device 100, so that the internal aerosol is actively discharged from the outlet 231 of the air outlet channel 23 through the exhaust structure.

[0058] In some embodiments, a plurality of sharp protrusions (not shown) are provided on the inner wall surface of the outlet 231. The sharp protrusions can prevent the condensate from forming a liquid film at the outlet 231, thereby preventing the liquid film formed at the outlet 231 from breaking during suction to form droplets to be sucked by the user. It is understandable that the sharp protrusions can puncture the liquid film, and the punctured condensate droplets flow back to the inside of the atomizer 10, thereby preventing the condensate droplets from flowing out of the outlet 231 and affecting the user experience.

[0059] In some embodiments, along the outlet direction of the outlet 231 in the outlet channel 23, the projection of the outlet side 321 of the atomizer core 32 at least partially overlaps with the projection of the outlet 231 of the air flow channel 2, wherein when the projection of the outlet side 321 of the atomizer core 32 completely overlaps with the projection of the outlet 231, the channel between the outlet side 321 of the atomizer core 32 and the outlet 231 is a straight line, and the channel does not need to turn, so that the particulate matter in the aerosol can be taken out by the gas to the greatest extent. Continue reading Figures 3 to 7 In other embodiments, along the outlet direction of the outlet 231, the projection of the outlet side 321 of the atomizer core 32 does not overlap with the projection of the outlet 231 of the air flow channel 2, for example Figures 3 to 6The projection of the air outlet side 321 of the atomizer core 32 is shown below the projection of the outlet 231. Figure 7 The projection of the air outlet side 321 of the atomizer core 32 is shown to be located above the projection of the outlet 231 .

[0060] The following will specifically focus on Figures 3 to 7 The design form of the air flow channel 2 shown in the figure is an exemplary illustration of the structure of the atomizer 10, wherein the atomizer can be applicable to an integrated electronic atomization device and a cartridge-changing electronic atomization device. Specifically, the power supply assembly 20 includes a second shell 201 and a battery compartment 202 located in the second shell 201, and a battery 203 is arranged in the battery compartment 202, and the battery 203 can be used to provide the atomization assembly 3 with the voltage required for operation.

[0061] See also Figures 3 to 6 For an integrated electronic atomization device, the interior of the atomization bracket 31 constitutes an installation chamber 101. The atomization core 32 is located in this installation chamber 101. The end of the atomization bracket 31 away from the liquid storage tank 11 can extend into the second shell 201, and the end of the atomization bracket 31 away from the liquid storage tank 11 can also be equipped with a battery 203. The second shell 201 can wrap the lower part of the atomization bracket 31, and the first shell 1 wraps the upper part of the atomization bracket 31, and the first shell 1 is wrapped by the second shell 201, thereby forming the overall outline of the electronic atomization device 100.

[0062] See also Figure 7 For a cartridge-type electronic atomization device in which the atomizer 10 can be replaced, the interior of the atomization bracket 31 forms an installation chamber 101, and the atomization core 32 is located in the installation chamber 101. The entire structure of the atomization bracket 31 is located in the first shell 1, and the first shell 1 is wrapped by the second shell 201, thereby forming the overall outline of the electronic atomization device 100.

[0063] In addition, whether the electronic atomization device includes an integrated electronic atomization device or a cartridge-changing electronic atomization device, the air inlet 24 can be set at any position of the electronic atomization device. Figure 3 and Figure 7 As shown, the air inlet 24 can be arranged at the bottom or top of the second shell 201. In other embodiments, the air inlet 24 can also be arranged at the contact point between the first shell 1 and the second shell 201, that is, the gap at the contact point between the first shell 1 and the second shell 201 constitutes the air inlet 24.

[0064] See also Figure 3 to Figure 4In some embodiments, the air flow channel 2 of the atomizer 10 includes the following design form: the first air inlet channel 21 is arranged at the bottom of the atomizer bracket 31, and the first air inlet channel 21 is separated from the liquid storage tank 11. The second air inlet channel 22 is arranged in the atomizer bracket 31, along the air inlet direction of the second air inlet channel 22, the projection of the second inlet 221 of the second air inlet channel 22 is staggered with the projection of the air outlet side 321 of the atomizer core 32, and the projection of the second inlet 221 of the second air inlet channel 22 is farther away from the projection of the outlet 231 relative to the projection of the air outlet side 321 of the atomizer core 32. The air outlet channel 23 is located in the atomizer bracket 31, and the air outlet channel 23 is completely separated from the liquid storage tank 11.

[0065] According to the atomizer 10 of the design form of the air flow channel 2 of the embodiment of the present disclosure, on the one hand, the gas can fully bring the aerosol out from the outlet 231. On the other hand, since the air outlet channel 23 is completely separated from the liquid storage tank 11, the aerosol released from the air outlet side 321 of the atomizer core 32 will not contact the liquid storage tank 11, so the aerosol in the air outlet channel 23 and the liquid atomization medium in the liquid storage tank 11 will not affect each other.

[0066] Continue reading Figure 3 to Figure 4 The first inlet 211 is arranged on the outer bottom surface of the atomizing bracket 31, the second inlet 221 is arranged on the inner bottom surface of the atomizing bracket 31, and the outlet 231 is arranged on the outer side surface of the first housing 1. Therefore, the air inlet 24 is not the first inlet 211 of the first air inlet channel 21, and there should be an air inlet channel (not shown in the figure) between the air inlet 24 and the first inlet 211 of the first air inlet channel 21. The air inlet channel is connected with the first air inlet channel 21 to provide gas to the inside of the atomizer 10.

[0067] See also Figures 5 and 6 In other embodiments, the air flow channel 2 of the atomizer 10 includes the following design forms: the first air inlet channel 21 is arranged at the bottom of the atomizer bracket 31, and the first air inlet channel 21 is separated from the liquid storage tank 11. The second air inlet channel 22 is arranged in the atomizer bracket 31, and along the air inlet direction of the second air inlet channel 22, the projection of the second inlet 221 of the second air inlet channel 22 at least partially overlaps with the projection of the air outlet side 321 of the atomizer core 32. The air outlet channel 23 is located in the atomizer bracket 31, and the air outlet channel 23 is completely separated from the liquid storage tank 11.

[0068] According to the atomizer 10 of the design form of the air flow channel 2 of the embodiment of the present disclosure, on the one hand, the gas can also fully bring the aerosol out from the outlet 231. On the other hand, since the air outlet channel 23 is completely separated from the liquid storage tank 11, the aerosol released from the air outlet side 321 of the atomizer core 32 will not contact the liquid storage tank 11, so the aerosol in the air outlet channel 23 and the liquid atomization medium in the liquid storage tank 11 will not affect each other.

[0069] Continue reading Figures 5 and 6 The first inlet 211 is arranged on the outer bottom surface of the atomizing bracket 31, the second inlet 221 is arranged on the inner bottom surface of the atomizing bracket 31, and the outlet 231 is arranged on the outer side surface of the first shell 1, so Figure 3 The air inlet 24 shown is not the first inlet 211 of the first air inlet channel 21, and there should be an air inlet channel (not shown) between the air inlet 24 and the first inlet 211 of the first air inlet channel 21. The air inlet channel is connected to the first air inlet channel 21 to provide gas to the inside of the atomizer 10.

[0070] Continue reading Figure 7 In some other embodiments, part of the atomizer assembly 3 is arranged inside the liquid storage tank 11. The air flow channel 2 of the atomizer 10 includes the following design form: the first air inlet channel 21 is arranged in the first housing 1, and the first air inlet channel 21 passes through part of the liquid storage tank 11. The second air inlet channel 22 is also arranged in the first housing 1, and the second air inlet channel 22 also passes through part of the liquid storage tank 11. Along the air inlet direction of the second air inlet channel 22, the projection of the second inlet 221 of the second air inlet channel 22 overlaps at least partially with the projection of the air outlet side 321 of the atomizer core 32. The air outlet channel 23 is also arranged in the first housing 1. The air outlet side 321 of the atomizer core 32 is located inside the liquid storage tank 11, and the air outlet channel 23 is basically separated from the liquid storage tank 11, that is, along the air inlet direction of the second air inlet channel 22, the air outlet channel 23 has less overlapping parts with the liquid storage tank 11. Preferably, at least half of the air outlet channel 23 is separated from the liquid storage tank 11.

[0071] According to the atomizer 10 of the design form of the air flow channel 2 of the embodiment of the present disclosure, on the one hand, the gas can also fully bring the aerosol out from the outlet 231. On the other hand, since the air outlet channel 23 is basically separated from the liquid storage tank 11, the contact path length between the aerosol released from the air outlet side 321 of the atomization core 32 and the liquid storage tank 11 is significantly reduced, so the aerosol in the air outlet channel 23 and the liquid atomization medium in the liquid storage tank 11 have less influence on each other.

[0072] Continue reading Figure 7 The air inlet 24 is arranged on the outer top surface of the first housing 1, and the first inlet 211 is also arranged on the outer top surface of the first housing 1, so the air inlet 24 is the first inlet 211 of the first air inlet channel 21. The second inlet 221 is located inside the first housing 1 and arranged on the inner wall of the installation chamber 101, and the outlet 231 is arranged on the outer side surface of the first housing 1.

[0073] In summary, the above has been based on Figures 3 to 7The design form of the air flow channel 2 shown is an exemplary description of the structure of the atomizer 10. In the following, the arrangement form of the fluid channel of the atomizer 10 will be mainly described in the case where the atomizer core 32 includes a ceramic atomizer core.

[0074] Figure 8 Shown according to Figure 4 The schematic diagram of the structure of the atomization assembly 3 of the electronic atomization device 100 is shown. Fig. 9 Shown according to Figure 8 An exploded schematic diagram of the atomization assembly 3 is shown. Fig.10 Shown according to Figure 5 The schematic diagram of the structure of the atomization assembly 3 of the electronic atomization device 100 is shown. Fig.11 Shown according to Fig.10 An exploded schematic diagram of the atomization assembly 3 is shown. Fig.12 Shown according to Figure 6 The schematic diagram of the structure of the atomization assembly 3 of the electronic atomization device 100 is shown. Fig.13 Shown according to Fig.12 The exploded schematic diagram of the atomization assembly 3 is shown. Figures 8 to 13 The atomizer cores 32 shown are all ceramic atomizer cores. The atomizer assembly 3 includes a mounting member 33 and a sealing member 34. The sealing member 34 is sleeved on the outer side of the end of the mounting member 33 facing the liquid storage tank 11, and the sealing member 34 is connected to the inner wall surface of the first shell 1 to prevent the atomized medium in the liquid storage tank 11 from leaking outward. The mounting member 33 is arranged at the end of the atomizer bracket 31 close to the liquid storage tank 11. At least one first fluid channel 312 is arranged at one end of the atomizer bracket 31 close to the liquid storage tank 11. At least one second fluid channel 331 is arranged at one end of the mounting member 33 close to the liquid storage tank 11. The second fluid channel 331 is connected to the liquid storage tank 11, and the first fluid channel 312 and the second fluid channel 331 connect the liquid storage tank 11 and the atomizer core 32, so the atomizer core 32 can receive the atomized medium from the liquid storage tank 11 through the first fluid channel 312 and the second fluid channel 331.

[0075] It should be noted that the seal 34 according to the embodiment of the present disclosure may be any type of seal 34 currently known or available in the future, and the embodiment of the present disclosure is not limited thereto. For example, in some embodiments, the seal 34 may be silicone.

[0076] Continue reading Figures 8 to 13In some embodiments, a buffer groove 311 is further provided at one end of the atomizer bracket 31 close to the liquid storage tank 11, and the first fluid channel 312 is connected to the buffer groove 311. The mounting member 33 covers the buffer groove 311 of the atomizer bracket 31 to form a buffer chamber (not shown in the figure). The buffer chamber is also connected to the atomizer core 32 through the first fluid channel 312. At least one auxiliary fluid channel 332 is also provided on the mounting member 33, and one end of the at least one auxiliary fluid channel 332 is connected to the liquid storage tank 11, and the other end is connected to the buffer chamber.

[0077] With the above configuration, when the atomizing medium in the liquid storage tank 11 is sufficient, the atomizing medium flows from the liquid storage tank 11 to the atomizing core 32 through the second fluid channel 331 and the first fluid channel 312. In addition, since one end of at least one auxiliary fluid channel 332 is connected to the liquid storage tank 11 and the other end is connected to the buffer chamber, the atomizing medium can flow into and be stored in the buffer chamber through the auxiliary fluid channel 332. When the atomizing medium in the liquid storage tank 11 is less, the atomizing medium stored in the buffer chamber can flow into the atomizing core 32, so that no matter whether the atomizing medium in the liquid storage tank 11 is sufficient, it is ensured that the atomizing core 32 always has atomizing medium entering, thereby preventing the atomizing core 32 from dry burning.

[0078] In some embodiments, at least one auxiliary fluid channel 332 includes an auxiliary fluid channel 332, and the auxiliary fluid channel 332 is disposed adjacent to the suction nozzle 12 along the air outlet direction of the outlet 231. Since the atomized medium generally gathers on the side close to the suction nozzle 12 when the user is inhaling, the auxiliary fluid channel 332 is disposed adjacent to the suction nozzle 12, so that the remaining atomized medium in the liquid storage tank 11 can be consumed, thereby avoiding waste of the atomized medium.

[0079] Continue reading Figure 4 , Figures 8 to 9 , Figure 5 , Figure 10 to Figure 11 as well as Figure 6 , Figure 12 to Figure 13 In other embodiments, the at least one auxiliary fluid channel 332 includes two auxiliary fluid channels 332. Along the gas outlet direction of the outlet 231, one of the auxiliary fluid channels 332 is disposed adjacent to the suction nozzle 12, and the other is disposed away from the suction nozzle 12, and the two auxiliary fluid channels 332 are symmetrically disposed. The auxiliary fluid channels 332 in this embodiment can also achieve the effect of avoiding waste of atomized medium, which will not be described in detail herein.

[0080] Continue reading Figure 4 , Figure 8 as well as Fig. 9In some embodiments, the end of the atomizer bracket 31 close to the liquid storage tank 11 can pass through the second fluid channel 331 of the mounting member 33, for example, the end of the first fluid channel 312 away from the atomizer core 32 is located inside the second fluid channel 331, or the end of the first fluid channel 312 away from the atomizer core 32 is flush with the end of the second fluid channel 331 away from the atomizer core 32. Figures 10 to 13 As shown, in other embodiments, the first fluid channel 312 and the corresponding second fluid channel 331 are sequentially arranged and connected along the air intake direction of the second air intake channel 22. The number of the first fluid channel 312 can be one, or two or more. The number of the second fluid channel 331 can be one, or two or more. Figures 8 to 13 The design forms of the first fluid channel 312 and the second fluid channel 331 in the atomizing assembly 3 are exemplarily described.

[0081] Continue reading Figure 4 as well as Figures 8 to 9 In some embodiments, one end of the atomizer bracket 31 away from the atomizer core 32 passes through the second fluid channel 331 of the mounting member 33. For example, one end of the first fluid channel 312 away from the atomizer core 32 is located inside the second fluid channel 331, or one end of the first fluid channel 312 away from the atomizer core 32 is flush with one end of the second fluid channel 331 away from the atomizer core 32.

[0082] In this embodiment, the number of the first fluid channel 312 and the number of the second fluid channel 331 are one. The second fluid channel 331 is connected to the liquid storage tank 11. The first fluid channel 312 is located in the middle position of the atomization bracket 31 and is connected to the atomization core 32 and the second fluid channel 331 respectively. Therefore, the liquid atomization medium in the liquid storage tank 11 flows into the middle position of the atomization core 32 through the second fluid channel 331 and the first fluid channel 312.

[0083] Continue reading Figure 5 as well as Figure 10 to Figure 11 In other embodiments, the first fluid channel 312 and the corresponding second fluid channel 331 are sequentially arranged and connected along the air intake direction of the second air intake channel 22 .

[0084] In this embodiment, the number of the first fluid channel 312 and the number of the second fluid channel 331 are two, and the two first fluid channels 312 and the two second fluid channels 331 are arranged and connected in a one-to-one correspondence. The two first fluid channels 312 are respectively connected to the two ends of the atomizer core 32. The two second fluid channels 331 are respectively connected to the liquid storage tank 11. Therefore, the liquid atomization medium in the liquid storage tank 11 flows into the two ends of the atomizer core 32 through the second fluid channel 331 and the corresponding first fluid channel 312.

[0085] Continue reading Figure 6 as well as Figure 12 to Figure 13 In some other embodiments, the first fluid channel 312 and the corresponding second fluid channel 331 are sequentially arranged and connected along the air intake direction of the second air intake channel 22 .

[0086] In this embodiment, the number of the first fluid channel 312 is one, and the number of the second fluid channels 331 is two. The first fluid channel 312 is connected to the atomizer core 32. The two second fluid channels 331 are respectively connected to the liquid storage tank 11. The liquid atomization medium in the liquid storage tank 11 flows into the atomizer core 32 through the second fluid channel 331 and the first fluid channel 312.
