[0038] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood 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 attached Figure 1 To Attachment Fig.15 As shown, the 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 pull rod 2, movably arranged on the liquid cup 1;

[0044] A linkage member 3, movably sleeved on the atomizer core assembly 100;

[0045] The pulling rod 2 is detachably connected to the linkage member 3; the linkage member 3 seals the atomizer core assembly 100 when it is in the initial position; 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 of 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 with the aerosol matrix, and does not need to be soaked in the aerosol matrix, so as to prevent the aerosol matrix from leaking out from 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 users to use and meets the needs of users.

[0047] As attached Figure 3 To Attachment Figure 8 and attached Fig.10 To Attachment Fig.11 As shown, further, the linkage member 3 is provided with a receiving cavity 31 for receiving the atomizer core assembly 100, and the pull-out rod 2 is partially inserted in the receiving cavity 31 and is interference fit with the linkage member 3. The pull-out rod 2 and the linkage member 3 are interference fit, so that the pull-out rod 2 can not only pull the linkage member 3 from the initial position to the limit position when the liquid core is separated and switched to the liquid core is combined, but also can continue to pull the pull-out rod 2 after the linkage member 3 reaches the limit position, so that the pull-out rod 2 is separated from the linkage member 3, which is convenient for users to use and switch to the liquid core combined state in time.

[0048] Furthermore, the atomizer is also provided with a suction nozzle 21, through which the user inhales the aerosol generated by the atomizer core assembly 100. When connected, the pull-out rod 2 passes through the suction nozzle 21 and is inserted into the accommodating cavity 31 and is interference-fitted with the linkage 3. When the linkage 3 reaches the limit position, the pull-out rod 2 is continued to be pulled, so that the pull-out rod 2 is pulled out from the suction nozzle 21, and the pull-out rod 2 can be leaked out for the user to inhale. The pull-out rod 2 can also seal the suction nozzle 21 when the liquid core is separated, so as to prevent the suction nozzle 21 from being contaminated during long-term storage and transportation, thereby ensuring safety in use.

[0049] As attached Figure 3To Attachment Figure 8 and attached Fig.10 To Attachment Fig.11 As shown, further, the linkage member 3 is provided with a connecting piece 32 located in the accommodating cavity 31, and the pulling 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 the limit position. The connecting piece 32 can not only be used to connect with the pulling rod 2, but also can be used as a limit block to abut against the liquid cup 1, that is, the lower end of the suction nozzle 21. At this time, the linkage member 3 moves to the limit position, and it is also convenient to pull out the pulling rod 2 later, so that the pulling rod 2 is disconnected from the linkage member 3, and it is convenient to pull out the pulling rod 2.

[0050] As attached Figure 3 To Attachment Figure 8 and attached Fig.10 To Attachment Fig.11 As shown, further, a first through hole 33 for the pull-out rod 2 to pass through is provided on the connecting piece 32, and the pull-out rod 2 is detachably connected to the linkage member 3 by interference fit with the first through hole 33. The pull-out rod 2 is interference fit with the linkage member 3 by passing through the first through hole 33, which facilitates the pull-out rod 2 to be pulled out in subsequent use, and facilitates the user to switch from the liquid core separation state to the liquid core combination state in time 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 member 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 member 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 axial direction is arranged 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, and 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, and when the pulling rod 2 pulls the linkage 3 to move from the initial position to the extreme position, the step abuts against the connecting piece 32, and 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 Attachment Figure 8 As shown, further, a first sealing ring 4 is provided on the liquid cup 1, and when the linkage member 3 is located at the initial position and the limit position, the first sealing ring 4 is located in the accommodating cavity 31 and is sealed and connected with the linkage member 3. The atomizer core assembly 100 is sealed when the liquid core is separated, and the aerosol matrix is ​​prevented from leaking out from the airway after infiltrating into the atomizer core assembly 100, so as to maintain the freshness of the aerosol matrix, facilitate replacement, maintenance, cleaning, and long-term storage and transportation after liquid injection. At the same time, after the linkage member 3 reaches the limit position, the friction between the first sealing ring 4 and the linkage member 3 is greater than the gravity of the linkage member 3 itself, so that the linkage member 3 is kept at the limit position, that is, the liquid core is kept combined, which is convenient for users to use and meets the needs of users.

[0054] As attached Figure 3 To Attachment Figure 8 and attached Fig.12 As shown, further, a fixing member 5 is provided between the first sealing ring 4 and the atomizer core assembly 100, and a guide column 51 is provided on the fixing member 5, and a guide hole 34 for inserting the guide column 51 is provided on the connecting piece 32. When the pulling rod 2 pulls the linkage member 3 to move from the initial position to the limit position, the fixing member 5 provides a guiding function for the linkage member 3 to ensure that the state of liquid core separation is switched to the state of liquid core combination in time.

[0055] As attached Figure 3 To Attachment Figure 8 and attached Fig.13 As shown, further, a second sealing ring 6 is also provided on the liquid cup 1. When the linkage member 3 is located at the initial position, the second sealing ring 6 is located in the accommodating cavity 31 and is sealed and connected with the linkage member 3; when the linkage member 3 is located at the extreme position, the second sealing ring 6 and the linkage member 3 are released from the sealed connection, 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 atomization core assembly 100 in conjunction with the first sealing ring 4 when the liquid core is separated in the initial position, to prevent the aerosol matrix from leaking out from the airway after infiltrating into the atomization core assembly 100, to maintain the freshness of the aerosol matrix, and to facilitate 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 and condensate leak out, they are stored in the gap 87. At the same time, the collected aerosol matrix can be further absorbed by the absorbent cotton 8, which is beneficial to secondary absorption and atomization.

[0057] Furthermore, the liquid inlet hole 35 is in a ring shape, which facilitates the lower end of the liquid absorbent cotton 8 to be completely immersed in the aerosol matrix, thereby increasing the flow rate of the aerosol matrix into the atomizer core assembly 100. At the same time, the liquid inlet hole 35 can also be in the shape of multiple openings, which facilitates the aerosol matrix to enter the atomizer core assembly 100.

[0058] As attached Figure 3 To Attachment Figure 8 and attached Fig.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 for guiding the aerosol medium from the outer liquid tank 11 to the inner liquid tank 12 is arranged between the outer liquid tank 11 and the inner liquid tank 12, and a liquid absorbent cotton 8 for guiding the aerosol medium from the inner liquid tank 12 to the atomization core assembly 100 is arranged in the atomization tank 13, and the atomization core assembly 100 is arranged in the liquid absorbent 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 change of density. 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 to control the liquid inlet speed. In addition, 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 to flow 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 tank 13 will 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 liquid injection, thereby improving the user experience; at the same time, the aerosol matrix leaked into the atomizer tank 13 can also be supplied to the atomizer core assembly 100 when the liquid-core is combined, for the user to inhale and use, thereby reducing waste.

[0060] Furthermore, after the linkage part 3 reaches the extreme position, the friction between the first sealing ring 4 and the liquid absorbent 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 combined, which is convenient for users to use and meets the needs of users.

[0061] As attached Figure 3 To Attachment Figure 8 As shown, further, the liquid lock member 7 and the liquid absorbent cotton 8 are arranged in layers, and at least two layers are arranged, and the density of each layer is different. The layered arrangement facilitates the setting of different densities, so that the liquid lock member 7 and the liquid absorbent cotton 8 guide the aerosol matrix in different directions, and at the same time, the flow rate of the aerosol matrix can be slowed down to avoid leakage or seepage during placement and suction.

[0062] Furthermore, the liquid absorbent cotton 8 includes a first layer 81, a second layer 82 and a third layer 83 which are stacked from bottom to top in a direction away from the liquid inlet hole 35, the density of the first layer 81 is less than the density of the second layer 82, and the density of the second layer 82 is less than the density of the third layer 83. The density in the liquid absorbent cotton 8 gradually increases from bottom to top, and the aerosol matrix moves along a layer with a smaller density toward a layer with a larger density, that is, moves from bottom to top in the liquid absorbent cotton 8. Therefore, under the guidance of the liquid absorbent cotton 8, the aerosol matrix of the inner liquid tank 12 is absorbed from the liquid inlet hole 35 and transported upward, so that the aerosol matrix enters the atomizing core assembly 100, and the aerosol formed under the heating of the atomizing core assembly 100 controls the liquid inlet speed, and the liquid absorbent 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, the atomization tank 13 is arranged in the liquid absorbent cotton 8, and the liquid inlet hole 35 is arranged in an annular shape 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 level 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 0.04 g / 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 The aerosol matrix is ​​convenient to move from bottom to top under the guidance of the absorbent cotton 8.

[0067] Furthermore, a ventilation groove 84 is provided in the liquid absorbing cotton 8, which is connected to the liquid inlet hole 35 and the atomizing core assembly 100. The ventilation function of the liquid absorbing cotton 8 is enhanced to prevent the liquid absorbing cotton 8 from being insufficiently ventilated, causing the aerosol matrix to be unable to move upward, resulting in insufficient liquid supply to the atomizing core assembly 100, and further causing the atomizing core assembly 100 to burn empty and burn.

[0068] Furthermore, the liquid absorbent cotton 8 is provided with an inner hole 85 for placing the atomizer core assembly 100, the opening of one end of the ventilation groove 84 is arranged on the bottom surface of the first layer 81, and the opening of the other end of the ventilation groove 84 is arranged on the second layer 82 and on the side wall of the inner hole 85. The ventilation function of the liquid absorbent cotton 8 is enhanced to prevent the liquid absorbent cotton 8 from being insufficiently ventilated, causing 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 empty and burn.

[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 absorbent cotton 8 from being deformed when the linkage member 3 is pulled out. At the same time, the aerosol matrix needs to be conducted through the liquid absorbent cotton 8 for a certain distance to reach the atomizer core assembly 100, which effectively prevents liquid 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 supply the aerosol matrix to the second layer 82, and the liquid is supplied at both ends, which further prevents the atomizer core assembly 100 from burning out and scorching.

[0070] Furthermore, the atomizer core assembly 100 includes a heating element and a liquid guiding element sleeved outside the heating element. The liquid guiding 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 guiding element gradually increases from bottom to top, so that the aerosol matrix moves from bottom to top under the guidance of the liquid guiding element. At the same time, the heating element is arranged in the middle layer of the liquid guiding 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 the liquid is supplied at both ends, which further prevents the heating element from burning out and burning.

[0071] Furthermore, a pressure relief groove is provided in the liquid absorbent cotton 8 or a pressure relief groove is provided between the liquid absorbent cotton 8 and the fixing member 5 and the atomizer core assembly 100, which is beneficial to the balance of internal and external air pressure, prevents the aerosol matrix from penetrating easily, and avoids the atomizer core assembly 100 from burning out and scorching.

[0072] Furthermore, the diameter of the ventilation groove 84 is 0.2-0.4 mm. This ensures that the liquid absorbent cotton 8 has a strong ventilation effect, and at the same time does not affect the guiding effect of the liquid absorbent cotton 8 on the aerosol matrix. Furthermore, taking the diameter of the liquid absorbent cotton 8 as 9-10 mm as an example, the diameter of the inner hole 85 is 5 mm, and the diameter of the ventilation groove 84 is 0.3 mm.

[0073] Furthermore, the liquid lock member 7 includes an outer layer 71 close to the outer liquid tank 11 and an inner layer 72 close to the inner liquid tank 12, and the density of the outer layer 71 is less than that of the inner layer 72. The density in the liquid lock member 7 gradually increases from left to right, and the aerosol matrix moves along a layer with a smaller density toward a layer with a larger density, that is, moves from left to right in the liquid lock member 7. Therefore, under the guidance of the liquid lock member 7, the aerosol matrix is ​​sucked from the outer liquid tank 11 and transported to the inner liquid tank 12, reducing the backflow of the aerosol matrix, that is, reducing the flow rate of the aerosol matrix from the inner liquid tank 12 toward the outer liquid tank 11, and reducing the hydraulic pressure of the inner liquid tank 12 to prevent 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 moves 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 chamber 12 to prevent leakage during suction.

[0075] Furthermore, the liquid lock member 7 is made of a mixture of PA and PET, and each layer has a different density by adjusting the mixing ratio of PA and PET, so that 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 0.06 g / cm 3 The density of the inner layer 72 is 0.08 g / cm 3 The aerosol matrix is ​​convenient 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 attached Figure 2 To Attachment Fig.15 As shown, based on the above-mentioned atomizer, the embodiment of the present application also provides an aerosol generating device, including the atomizer.
