Such a structure inevitably prevents the aerosol matrix from leaking out of the airway after penetrating into the atomizer core. This will seriously affect the user's experience of the nebulizer, especially during long-term storage or transportation after liquid injection. Therefore, the existing technology cannot meet our needs. Utility Model Content

The terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned drawings are intended to cover non-exclusive inclusions. The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0038] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0039] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings.

[0040] Please see the attached Figure 1 To the attached Figure 15 As shown, an embodiment of the present application provides an atomizer, comprising:

[0041] Liquid cup 1, used for storing aerosol matrix;

[0042] The atomizing core assembly 100 is disposed in the liquid cup 1;

[0043] A pulling rod 2, movably arranged on the liquid cup 1;

[0044] The linkage member 3 is movably mounted on the atomizer core assembly 100;

[0045] The pulling rod 2 is detachably connected to the linkage member 3; when the linkage member 3 is in the initial position, it seals the atomizer core assembly 100; when the pulling rod 2 is pulled to drive the linkage member 3 to move to the extreme position, the pulling rod 2 is pulled out, and at this time, the linkage member 3 releases the seal on the atomizer core assembly 100, so that the liquid cup 1 is in communication with the atomizer core assembly 100.

[0046] The linkage member 3 can seal the atomizer core assembly 100 when it is in the initial position, that is, the liquid-core is separated, and the atomizer core assembly 100 does not need to contact the aerosol matrix, let alone be soaked in the aerosol matrix, thereby preventing the aerosol matrix from leaking out of the airway after penetrating into the atomizer core assembly 100, thereby maintaining the freshness of the aerosol matrix, facilitating replacement, maintenance, cleaning, and long-term storage and transportation after liquid injection, thereby improving the user experience; at the same time, when the present application is in use, the linkage member 3 can also release the seal of the atomizer core assembly 100 when it is in the extreme position driven by the pull-out rod 2, that is, the liquid-core is combined, which is convenient for user use and meets the needs of the user.

[0047] As attached Figure 3 To the attached Figure 8 and attached Figure 10 To the attached Figure 11 As shown, further, the linkage member 3 is provided with a receiving cavity 31 for accommodating the atomizer core assembly 100, and the pull-out rod 2 is partially inserted into the receiving cavity 31 and is interference-fitted with the linkage member 3. The pull-out rod 2 and the linkage member 3 are interference-fitted, so that the pull-out rod 2 can pull the linkage member 3 from the initial position to the extreme position when switching from liquid core separation to liquid core engagement, and can also continue to pull the pull-out rod 2 after the linkage member 3 reaches the extreme position, so that the pull-out rod 2 and the linkage member 3 are separated, which is convenient for the user to use and switch to the liquid core engagement state in a timely manner.

[0048] Furthermore, the atomizer is also provided with a mouthpiece 21, through which the user inhales the aerosol generated by the atomizer core assembly 100. When connected, the withdrawal rod 2 partially passes through the mouthpiece 21 and is inserted into the accommodating cavity 31, and is interference-fitted with the linkage 3. When the linkage 3 reaches its limit position, the withdrawal rod 2 is continued to be pulled, thereby withdrawing the withdrawal rod 2 from the mouthpiece 21, thereby leaking the withdrawal rod 2 and allowing the user to inhale. The withdrawal rod 2 also seals the mouthpiece 21 when the liquid core is separated, preventing the mouthpiece 21 from being contaminated during long-term storage and transportation, ensuring safe use.

[0049] As attached Figure 3To the attached Figure 8 and attached Figure 10 To the attached Figure 11 As shown, the linkage member 3 is further provided with a connecting piece 32 located within the accommodating cavity 31. The withdrawal rod 2 is interference-fitted with the connecting piece 32. When the connecting piece 32 abuts against the liquid cup 1, the linkage member 3 moves to its limit position. The connecting piece 32 is not only used to connect with the withdrawal rod 2, but also serves as a stopper against the liquid cup 1, i.e., the lower end of the suction nozzle 21. At this time, the linkage member 3 moves to its limit position, which also facilitates the subsequent pulling of the withdrawal rod 2, so that the withdrawal rod 2 is disconnected from the linkage member 3, making it easier to withdraw the withdrawal rod 2.

[0050] As attached Figure 3 To the attached Figure 8 and attached Figure 10 To the attached Figure 11 As shown, the connecting piece 32 is further provided with a first through hole 33 for the withdrawal rod 2 to pass through. The withdrawal rod 2 is interference-fitted with the first through hole 33, so that the withdrawal rod 2 and the linkage member 3 are detachably connected. The withdrawal rod 2 is interference-fitted with the linkage member 3 by passing through the first through hole 33, which facilitates the withdrawal of the withdrawal rod 2 during subsequent use, and facilitates the user to promptly switch from the liquid core separation state to the liquid core connection state for use.

[0051] Furthermore, the connecting piece 32 is circular in shape, and the first through hole 33 is coaxially arranged on the connecting piece 32. The circular connecting piece 32 can abut against the liquid cup 1 more stably. Of course, the connecting piece 32 can also be set to an elastic material, or a buffer part can be set at the position where the connecting piece 32 and / or the liquid cup 1 abut each other to avoid damage to the connecting piece 32 or the liquid cup 1 due to a hard collision between the connecting piece 32 and the liquid cup 1 when the linkage part 3 moves to the extreme position.

[0052] Furthermore, the pulling rod 2 is made of silicone, and the pulling rod 2 includes a main body 22 and a boss 23 protruding away from the axis at the lower end of the outer peripheral surface of the pulling rod 2. The diameter of the boss 23 is larger than the diameter of the first through hole 33, so that a step is formed between the boss 23 and the main body 22. When connected, the boss 23 passes through the first through hole 33 so that the pulling rod 2 and the linkage 3 have an interference fit. When the pulling rod 2 pulls the linkage 3 from the initial position to the extreme position, the step abuts against the connecting piece 32. When the linkage 3 reaches the extreme position, the pulling rod 2 continues to be pulled, so that the boss 23 is deformed and disengaged from the first through hole 33, thereby pulling the pulling rod 2 out of the suction nozzle 21.

[0053] As attached Figure 3 To the attached Figure 8 As shown, further, a first sealing ring 4 is provided on the liquid cup 1. When the linkage member 3 is in the initial position and the extreme position, the first sealing ring 4 is located in the accommodating cavity 31 and is sealed with the linkage member 3. This seals the atomizer core assembly 100 when the liquid core is separated, preventing the aerosol matrix from leaking out of the airway after infiltrating into the atomizer core assembly 100, maintaining the freshness of the aerosol matrix, and facilitating replacement, maintenance, cleaning, and long-term storage and transportation after liquid injection. At the same time, when the linkage member 3 reaches the extreme position, the friction between the first sealing ring 4 and the linkage member 3 is greater than the weight of the linkage member 3 itself, so that the linkage member 3 remains in the extreme position, that is, the liquid core remains connected, which is convenient for users to use and meets their needs.

[0054] As attached Figure 3 To the attached Figure 8 and attached Figure 12 As shown, a fixing member 5 is further provided between the first sealing ring 4 and the atomizer core assembly 100. The fixing member 5 is provided with a guide post 51, and the connecting piece 32 is provided with a guide hole 34 for inserting the guide post 51. When the pulling rod 2 pulls the linkage member 3 from the initial position to the extreme position, the fixing member 5 provides a guide for the linkage member 3 to ensure that the liquid core is switched from the liquid core separation state to the liquid core connection state in a timely manner.

[0055] As attached Figure 3 To the attached Figure 8 and attached Figure 13 As shown, further, a second sealing ring 6 is provided on the liquid cup 1. When the linkage member 3 is in the initial position, the second sealing ring 6 is located in the accommodating cavity 31 and is sealed with the linkage member 3. When the linkage member 3 is in the extreme position, the second sealing ring 6 is released from the sealing connection with the linkage member 3, so that a liquid inlet hole 35 is formed between the linkage member 3 and the second sealing ring 6. The second sealing ring 6 is used to seal the atomizer core assembly 100 in conjunction with the first sealing ring 4 in the initial position, that is, when the liquid core is separated, to prevent the aerosol matrix from leaking out of the airway after infiltrating into the atomizer core assembly 100, thereby maintaining the freshness of the aerosol matrix and facilitating replacement, maintenance, cleaning, and long-term storage and transportation after liquid injection.

[0056] Furthermore, a fastener 86 is provided inside the absorbent cotton 8, and a gap 87 is provided between the absorbent cotton 8 and the fastener 86. Even if aerosol matrix or condensate leaks out, it is stored in the gap 87. At the same time, the collected aerosol matrix can be further absorbed by the absorbent cotton 8, which is conducive to secondary absorption and atomization.

[0057] Furthermore, the liquid inlet 35 is annular in shape, which facilitates the complete immersion of the lower end of the absorbent cotton 8 in the aerosol matrix, thereby increasing the flow rate of the aerosol matrix into the atomizer core assembly 100. Furthermore, the liquid inlet 35 can also be in the shape of multiple openings to facilitate the entry of the aerosol matrix into the atomizer core assembly 100.

[0058] As attached Figure 3 To the attached Figure 8 and attached Figure 14 As shown, further, the liquid cup 1 is provided with an outer liquid tank 11, an inner liquid tank 12 and an atomization tank 13, the atomization tank 13 is arranged in the linkage part 3, and a liquid locking part 7 is provided between the outer liquid tank 11 and the inner liquid tank 12 for guiding the aerosol medium from the outer liquid tank 11 to the inner liquid tank 12, and a liquid absorbing cotton 8 is provided in the atomization tank 13 for guiding the aerosol medium from the inner liquid tank 12 to the atomization core assembly 100, and the atomization core assembly 100 is arranged in the liquid absorbing cotton 8. Multiple liquid tanks are provided, which not only have a large liquid storage capacity but also disperse the hydraulic pressure, so that the internal hydraulic pressure of the outer liquid tank 11 and the inner liquid tank 12 is greatly reduced to avoid leakage. At the same time, the circulation of the aerosol matrix between the outer liquid tank 11 and the inner liquid tank 12 is guided by the liquid locking component 7. The liquid locking component 7 can effectively slow down the flow rate of the aerosol matrix and reduce the hydraulic pressure of the inner liquid tank 12 by adjusting the density change. The inner liquid tank 12 guides the aerosol matrix into the atomization core assembly 100 through the guiding effect of the liquid absorbent cotton 8, controls the liquid inlet speed, and the liquid absorbent cotton 8 has a strong liquid locking effect to prevent leakage during suction.

[0059] Furthermore, the absorbent cotton 8 can not only guide the aerosol medium from the inner liquid tank 12 to the atomizer core assembly 100, but also when the linkage 3 is in the initial position to seal the atomizer core assembly 100, that is, the liquid core is separated, even if a small amount of leakage occurs at this time, the aerosol matrix leaked into the atomizer chamber 13 will also be absorbed by the absorbent cotton 8, forming a secondary protection, preventing the aerosol matrix from leaking out of the airway after infiltrating into the atomizer core assembly 100, maintaining the freshness of the aerosol matrix, facilitating replacement, maintenance, cleaning, and long-term storage and transportation after filling, thereby improving the user experience; at the same time, the aerosol matrix leaked into the atomizer chamber 13 can also be supplied to the atomizer core assembly 100 when the liquid core is combined, for the user to inhale and use, reducing waste.

[0060] Furthermore, after the linkage part 3 reaches the extreme position, the friction between the first sealing ring 4 and the liquid-absorbing cotton 8 and the linkage part 3 is greater than the gravity of the linkage part 3 itself, so that the linkage part 3 remains in the extreme position, that is, the liquid core is kept connected, which is convenient for users to use and meets the needs of users.

[0061] As attached Figure 3 To the attached Figure 8 As shown, the liquid-locking member 7 and the liquid-absorbing cotton 8 are arranged in layers, and at least two layers are provided, and each layer has a different density. The layered arrangement facilitates the setting of different densities, thereby allowing the liquid-locking member 7 and the liquid-absorbing cotton 8 to guide the aerosol matrix in different directions, while also slowing the flow rate of the aerosol matrix, thereby preventing leakage or seepage during placement and suction.

[0062] Furthermore, the liquid-absorbing cotton 8 includes a first layer 81, a second layer 82, and a third layer 83 stacked in sequence from bottom to top in a direction away from the liquid inlet hole 35. The density of the first layer 81 is less than that of the second layer 82, and the density of the second layer 82 is less than that of the third layer 83. The density within the liquid-absorbing cotton 8 gradually increases from bottom to top, and the aerosol matrix moves along the layer with lower density toward the layer with higher density, that is, moves from bottom to top within the liquid-absorbing cotton 8. Therefore, under the guidance of the liquid-absorbing cotton 8, the aerosol matrix in the inner liquid reservoir 12 is absorbed from the liquid inlet hole 35 and transported upward, so that the aerosol matrix enters the atomizer core assembly 100 and forms an aerosol under the heating of the atomizer core assembly 100, thereby controlling the liquid inlet speed. In addition, the liquid-absorbing cotton 8 has a strong liquid-locking effect to prevent leakage during suction.

[0063] Furthermore, the liquid cup 1 includes an outer shell 14 and an inner shell 15 arranged in the outer shell 14. The gap between the outer shell 14 and the inner shell 15 forms the outer liquid tank 11, the inner liquid tank 12 is arranged in the inner shell 15, and the atomization tank 13 is arranged in the liquid absorbent cotton 8. The liquid inlet hole 35 is annularly arranged to facilitate the lower end of the liquid absorbent cotton 8 to be completely immersed in the aerosol matrix.

[0064] Furthermore, the outer shell 14 can also be set to be transparent or translucent to facilitate observation of the liquid amount in the outer liquid tank 11. At the same time, fluorescent material can be placed in the outer liquid tank 11 to make the multi-liquid tank atomizer full of dynamics when shaking, thereby improving the visual effect.

[0065] Furthermore, the density of the first layer 81 is 0.03-0.05 g / cm 3 The density of the second layer 82 is 0.05-0.07 g / cm 3 The density of the third layer 83 is 0.07-0.09 g / cm 3 Each layer is set with a suitable density, and a suitable density difference is set between the two layers, so that the aerosol matrix moves from bottom to top under the guidance of the absorbent cotton 8 and flows into the atomizing core assembly 100.

[0066] Furthermore, the absorbent cotton 8 is made of a mixture of PA and PP, and each layer has a different density by adjusting the mixing ratio of PA and PP. The density of the first layer 81 is 0.04g / cm 3 The density of the second layer 82 is 0.06 g / cm 3 The density of the third layer 83 is 0.08 g / cm 3 . It is convenient for the aerosol matrix to move from bottom to top under the guidance of the absorbent cotton 8.

[0067] Furthermore, the liquid-absorbing cotton 8 is provided with a ventilation groove 84 that connects the liquid inlet hole 35 and the atomizer core assembly 100. This enhances the ventilation function of the liquid-absorbing cotton 8 and prevents the aerosol matrix from being unable to move upward due to insufficient ventilation of the liquid-absorbing cotton 8, resulting in insufficient liquid supply to the atomizer core assembly 100, and further causing the atomizer core assembly 100 to burn out and become scorched.

[0068] Furthermore, the liquid-absorbing cotton 8 is provided with an inner hole 85 for accommodating the atomizer core assembly 100. The opening at one end of the ventilation groove 84 is provided on the bottom surface of the first layer 81, and the opening at the other end of the ventilation groove 84 is provided on the second layer 82 and on the sidewall of the inner hole 85. This strengthens the ventilation function of the liquid-absorbing cotton 8 and prevents the liquid-absorbing cotton 8 from being insufficiently ventilated, which would cause the aerosol matrix to be unable to move upward, resulting in insufficient liquid supply to the atomizer core assembly 100, and further causing the atomizer core assembly 100 to burn out and become scorched.

[0069] Furthermore, the atomizer core assembly 100 is arranged in the second layer 82, and the density of the third layer 83 is greater than that of the second layer 82. Therefore, the liquid absorption capacity of the third layer 83 is greater than that of the other two layers, which can not only prevent the third layer 83 from absorbing more aerosol matrix, but also improve the strength, and prevent the liquid-absorbing cotton 8 from being deformed when the linkage member 3 is pulled out. At the same time, the aerosol matrix needs to be conducted a certain distance through the liquid-absorbing cotton 8 to reach the atomizer core assembly 100, effectively preventing leakage. At the same time, the third layer 83 also has a liquid storage function. After the atomizer core assembly 100 absorbs the aerosol matrix in the second layer 82, the third layer 83 and the first layer 81 can both supply aerosol matrix to the second layer 82, and supply liquid at both ends, further preventing the atomizer core assembly 100 from burning out and burning.

[0070] Furthermore, the atomizing core assembly 100 includes a heating element and a liquid guide element sleeved outside the heating element. The liquid guide element can also be provided with three or more layers like the liquid absorbent cotton 8, and the liquid conductivity of each layer is different, that is, the density of each layer of the liquid guide element gradually increases from bottom to top, so that the aerosol matrix moves from bottom to top under the guidance of the liquid guide element. At the same time, the heating element is arranged in the middle layer of the liquid guide element, which can not only prevent the top layer from absorbing more aerosol matrix, but also improve the strength and effectively prevent leakage. At the same time, the top layer also has a liquid storage function. After the heating element absorbs the aerosol matrix in the middle layer, the top layer and the bottom layer can supply the aerosol matrix to the middle layer, and supply liquid at both ends, further preventing the heating element from burning empty and burning.

[0071] Furthermore, a pressure relief groove is provided in the liquid-absorbing cotton 8 or between the liquid-absorbing cotton 8 and the fixing member 5 and the atomizing core assembly 100, which is beneficial to the balance of internal and external air pressure, prevents the aerosol matrix from being difficult to penetrate, and avoids the atomizing core assembly 100 from burning out and being burnt.

[0072] Specifically, the diameter of the ventilation groove 84 is 0.2-0.4 mm. This ensures that the absorbent cotton 8 has a strong ventilation effect while also not affecting the absorbent cotton 8's ability to guide the aerosol matrix. Specifically, for example, if the absorbent cotton 8 has a diameter of 9-10 mm, the inner hole 85 has a diameter of 5 mm, and the ventilation groove 84 has a diameter of 0.3 mm.

[0073] Specifically, the liquid-locking member 7 includes an outer layer 71 on the side close to the outer liquid reservoir 11 and an inner layer 72 on the side close to the inner liquid reservoir 12. The density of the outer layer 71 is lower than that of the inner layer 72. The density within the liquid-locking member 7 gradually increases from left to right, and the aerosol matrix moves from the layer with lower density to the layer with higher density, that is, from left to right within the liquid-locking member 7. Therefore, under the guidance of the liquid-locking member 7, the aerosol matrix is ​​drawn from the outer liquid reservoir 11 and transported to the inner liquid reservoir 12, reducing the backflow of the aerosol matrix, that is, reducing the flow rate of the aerosol matrix from the inner liquid reservoir 12 toward the outer liquid reservoir 11, effectively slowing down the flow rate of the aerosol matrix and reducing the hydraulic pressure of the inner liquid reservoir 12, thereby preventing leakage during suction.

[0074] Furthermore, the density of the outer layer 71 is 0.04-0.06 g / cm 3 The density of the inner layer 72 is 0.06-0.09 g / cm 3 Each layer is set with a suitable density, and a suitable density difference is set between the two layers, so that the aerosol matrix can move from left to right under the guidance of the liquid lock member 7, effectively slowing down the flow rate of the aerosol matrix and reducing the hydraulic pressure of the inner liquid tank 12, thereby preventing leakage during suction.

[0075] Furthermore, the liquid lock member 7 is made of a mixture of PA and PET, and by adjusting the mixing ratio of PA and PET so that each layer has a different density, the liquid lock member 7 has a function similar to a one-way valve, that is, the aerosol matrix flows from the outer liquid tank 11 to the inner liquid tank 12 in one direction. The density of the outer layer 71 is 0.06g / cm 3 The density of the inner layer 72 is 0.08 g / cm 3 . It is convenient for the aerosol matrix to move from left to right under the guidance of the liquid locking member 7.

[0076] Furthermore, the liquid locking member 7 is a structure of porous ceramics, porous metals, porous glass, fiber parts, etc., which facilitates the aerosol matrix to move from left to right under the guidance of the liquid locking member 7.

[0077] Please see the attached Figure 2 To the attached Figure 15 As shown, based on the above-mentioned atomizer, the embodiment of the present application also provides an aerosol generating device, including the atomizer. The linkage 3 can seal the atomizer core assembly 100 when it is in the initial position, that is, the liquid core is separated, and the atomizer core assembly 100 does not need to contact the aerosol matrix, and does not need to be soaked in the aerosol matrix, preventing the aerosol matrix from leaking out from the airway after infiltrating into the atomizer core assembly 100, maintaining the freshness of the aerosol matrix, facilitating replacement, maintenance, cleaning, and long-term storage and transportation after injection, thereby improving the user experience; at the same time, when the present application is in use, the linkage 3 can also release the seal of the atomizer core assembly 100 when it is in the extreme position under the drive of the pull-out rod 2, that is, the liquid core is combined, which is convenient for user use and meets the needs of the user.

[0078] Furthermore, the aerosol generating device also includes a control panel 9 and a display module 90 disposed on the control panel 9. The display module 90 is electrically connected to the control panel 9. The inner shell 15 is further provided with a mounting cavity 16 located on one side of the inner liquid reservoir 12. The inner wall of the mounting cavity 16 is symmetrically provided with a slot 17, and the control panel 9 is mounted within the slot 17. A protective cover 18 for securing the control panel 9 is also mounted at the opening of the mounting cavity 16. The inner liquid reservoir 12 and the mounting cavity 16 are disposed on both sides of the inner shell 15, and the inner liquid reservoir 12 and the mounting cavity 16 are separately sealed. The two cavities are not connected to each other, effectively preventing aerosol from volatilizing or condensate from accumulating and entering the mounting cavity 16, thereby avoiding damage to the control panel 9, display module 90, etc.

[0079] Furthermore, the aerosol generating device also includes a microphone assembly, which includes a microphone 91 and a microphone silica gel 92 mounted on the microphone 91. The microphone 91 is electrically connected to the control panel 9. The lower end of the housing 14 is provided with a plug 93 and an air inlet 94 located inside the microphone silica gel 92. The air inlet 94 is provided on one side of the plug 93. At the same time, a microphone air path 95 is also provided inside the microphone silica gel 92. The microphone air path 95 is "S"-shaped or "bow"-shaped. A microphone liquid-absorbing cotton 96 is provided inside the microphone air path 95. The microphone liquid-absorbing cotton 96 is provided at the lower end of the microphone 91. This effectively prevents aerosol from volatilizing or condensation from accumulating and entering the microphone 91, preventing damage to the microphone 91 and preventing the occurrence of phenomena such as the microphone 91 automatically starting due to long-term storage.

[0080] Furthermore, the aerosol generating device further includes a button 97 , which is electrically connected to the control panel 9 . The button 97 is disposed on the housing 14 and located on one side of the nozzle 21 , making it convenient for the user to press the button 97 during use.
