Description

Technical Field

[0001] The present application relates to the technical field of atomization devices, and particularly to an atomizer, an atomization component applied thereto, and an electronic atomization device. Background Art

[0002] Currently, in electronic atomization devices such as electronic cigarettes, the heating element inside the cartridge is usually non-removable, which causes the user to be unable to replace the heating element. After the heating element is damaged, the user can only discard the entire cartridge, which is inconvenient for the user.

[0003] Moreover, traditional cartridges usually use capillary action to guide the e-liquid to the heating element for heating and atomization. However, when the atomization speed of the e-liquid is relatively fast, the air pressure in the e-liquid chamber decreases, and it is easy to have a situation where the liquid supply is not smooth. At this time, the e-liquid cannot be quickly replenished to the heating element, resulting in the heating element being dry-burned and overheated, which easily causes problems such as damage to the heating element, generation of burnt smell, and generation of harmful substances. Therefore, it is necessary to ventilate the e-liquid chamber in a timely manner.

[0004] However, traditional cartridges usually ventilate the e-liquid chamber through the heating element, which means that the e-liquid transmission channel and the ventilation channel in the traditional cartridge share the heating element, and there is a conflict between the two. The bubbles generated by ventilation are likely to block the e-liquid transmission channel, which will also cause the e-liquid to not be quickly replenished to the heating element, resulting in the heating element being dry-burned and overheated.

[0030] To make the objectives, technical solutions, and advantages of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the embodiments of the present application. Apparently, the described embodiments are some but not all of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application. Without conflict, the following embodiments and the features in the embodiments may be combined with each other.

[0031] To solve the technical problems in the prior art that the atomizer is inconvenient for users to use and the risk of dry burning and overheating of the atomization core is relatively high, an embodiment of the present application provides an atomizer. The atomizer includes a liquid storage component, an atomization component, and a base component; the liquid storage component and the base component are detachably connected, and the liquid storage component and the base component cooperate to form a receiving cavity. The liquid storage component is provided with a liquid storage cavity for storing an aerosol matrix; the atomization component includes a first housing and an atomization core. The first housing is detachably disposed in the receiving cavity. An atomization cavity is provided inside the first housing, and the atomization core is disposed in the atomization cavity for atomizing the aerosol matrix; the first housing is provided with a ventilation channel that communicates with the liquid storage cavity and also communicates to the outside of the atomizer. The following is a detailed elaboration.

[0032] Please refer to Figure 1 , Figure 1 A schematic structure diagram of an embodiment of the electronic atomization device of the present application.

[0033] In one embodiment, the electronic atomization device 10 may be an atomization device such as an electronic cigarette, which atomizes the internally stored e-liquid to form an aerosol for the user to inhale. Of course, the electronic atomization device 10 in this embodiment may also be a medical atomization device, etc., which atomizes the liquid medicine to form an aerosol for the patient to inhale.

[0034] The electronic atomization device 10 includes a power supply component 20 and an atomizer 30. The power supply component 20 serves as the control end of the electronic atomization device 10 and has a built-in power supply. The power supply component 20 is connected to the atomizer 30 to supply power to the atomizer 30, driving the atomizer 30 to atomize the aerosol matrix stored therein to form an aerosol mist. Based on the above, the electronic atomization device 10 can be an electronic cigarette, a medical atomization device, etc., and the aerosol matrix can correspondingly be e-liquid, liquid medicine, etc.

[0035] Please refer to Figures 2 to 4 , Figure 2 which is a schematic structural diagram of an embodiment of the atomizer of this application. Figure 3 is Figure 2 an exploded structural diagram of the atomizer shown. Figure 4 is Figure 2 a cross-sectional structural diagram of the atomizer shown in the A-A direction.

[0036] In one embodiment, the atomizer 30 includes a liquid storage component 40, an atomization component 50, and a base component 60. The liquid storage component 40 is provided with a liquid storage cavity 41 for storing the aerosol matrix. The atomization component 50 serves as the atomization element of the atomizer 30 and is used to atomize the aerosol matrix to form an aerosol mist for the user to inhale. Among them, the above power supply component is connected to the atomization component 50 to supply power to the atomization component 50 and control the atomization component 50 to atomize the aerosol matrix. The base component 60 is the basic carrier of the atomizer 30. The liquid storage component 40 and the atomization component 50 are both arranged on the base component 60 and are assembled with the power supply component through the base component 60.

[0037] The atomization component 50 includes a first housing 51 and an atomization core 52. The liquid storage component 40 and the base component 60 cooperate to form an accommodation cavity 70, and the first housing 51 is arranged in the accommodation cavity 70. An atomization cavity 53 is provided inside the first housing 51, and the atomization core 52 is arranged in the atomization cavity 53. Among them, the atomization core 52 is the element in the atomization component 50 for atomizing the aerosol matrix. The aerosol matrix in the liquid storage cavity 41 is transmitted to the atomization core 52, atomized by the atomization core 52 to form an aerosol mist, and is inhaled by the user with the action of the user's suction.

[0038] The atomization core 52 can atomize the aerosol matrix by heating or other means. Of course, in other embodiments of this application, the atomization core 52 can also atomize the aerosol matrix by ultrasonic atomization or other means, which is not limited herein. As for the principles and corresponding structural designs of the atomization core 52 for heating atomization, ultrasonic atomization, etc., this belongs to the understanding scope of those skilled in the art and will not be elaborated herein.

[0039] Furthermore, please refer to Figure 5, the atomizer 30 of this embodiment can be applied to high-power electronic atomization devices. Specifically, to adapt to high-power electronic atomization devices, the first housing 51 and the atomization core 52 of this embodiment are both hollow columnar structures. Among them, the axial directions of the first housing 51 and the atomization core 52 are both parallel to the first direction (as shown by the arrow Y in Figure 4 and Figure 5 , the same below), and the liquid storage component 40 and the base component 60 are arranged oppositely along the first direction.

[0040] The side wall of the first housing 51 is provided with a liquid inlet 511. The liquid inlet 511 penetrates the side wall of the first housing 51 along a direction perpendicular to the axial direction of the first housing 51 to communicate with the liquid storage cavity 41. The liquid inlet 511 faces the outer peripheral surface of the atomization core 52. In other words, the liquid inlet 511 can be understood as parallel to the axial direction of the first housing 51. The aerosol matrix in the liquid storage cavity 41 reaches the atomization core 52 through the liquid inlet 511.

[0041] Optionally, the atomization core 52 can adopt a ceramic heating element, etc., to adapt to high-power electronic atomization devices, which is beneficial to providing a larger aerosol volume and can be applicable to scenarios where a large aerosol volume is provided.

[0042] Through the above method, the atomizer 30 of this embodiment can adapt to high-power electronic atomization devices. The designs of the first housing 51, the atomization core 52, and the liquid inlet 511 are beneficial to providing a larger aerosol volume and can be applicable to scenarios where a large aerosol volume is provided.

[0043] Please continue to refer to Figures 3 to 5 . In this embodiment, the liquid storage component 40 and the base component 60 are detachably connected, and the first housing 51 is detachably arranged in the accommodation cavity 70. In this way, by disassembling the liquid storage component 40 and the base component 60, the atomization component 50 can be removed from the accommodation cavity 70, realizing the detachable and replaceable design of the atomization component 50. When the atomization component 50 is damaged, the user does not need to abandon the entire atomizer 30. Just replace an atomization component 50 and it can be put back into use, thus facilitating the user. Specifically, the replaced atomization component 50 is installed in the liquid storage component 40 or the base component 60, and then the liquid storage component 40 and the base component 60 are reassembled.

[0044] Moreover, different from the situation in the prior art where the oil transmission channel and the ventilation channel 512 share the heating element, the first housing 51 of this embodiment is provided with a ventilation channel 512, that is, the ventilation channel 512 is independent of the atomization core 52. The ventilation channel 512 will not hinder the transmission of the aerosol matrix in the liquid storage cavity 41 to the atomization core 52, and can timely supplement the aerosol matrix at the atomization core 52. Therefore, the risk of dry burning and overheating of the atomization core 52 can be reduced, and problems such as damage to the atomization core 52, generation of burnt smell, and generation of harmful substances can be avoided as much as possible.

[0045] Traditional atomization components usually use the gaps between structural components or the gaps of atomization cores (such as cotton cores, etc.) for ventilation. The ventilation effect is directly related to the assembly conditions of the structural components and the atomization cores. However, due to the inability to ensure the consistency of the assembly conditions of the structural components and the atomization cores, the ventilation effect of traditional atomization components is often poor. In this embodiment, a ventilation channel 512 is provided in the first housing 51, and the ventilation channel 512 is independent of the atomization core 52. Therefore, the ventilation effect of the ventilation channel 512 is not affected by the assembly conditions of the atomization core 52, and the ventilation pressure can be accurately controlled, thereby ensuring the ventilation effect.

[0046] It should be noted that the ventilation channel 512 communicates with the liquid storage cavity 41 and also communicates to the outside of the atomizer 30. When the user sucks, the air flow outside the atomizer 30 reaches the liquid storage cavity 41 through the ventilation channel 512 to supplement the air pressure in the liquid storage cavity 41, and as much as possible to avoid the aerosol matrix in the liquid storage cavity 41 being unable to be transmitted to the atomization core 52 for atomization due to too low air pressure in the liquid storage cavity 41.

[0047] Please continue to refer to Figure 3 and Figure 4 . In an embodiment, the liquid storage assembly 40 includes a second housing 42 and a third housing 43. The second housing 42 is embedded in the third housing 43, and the second housing 42 is sleeved on the outer periphery of the first housing 51. A liquid storage cavity 41 is formed between the second housing 42 and the third housing 43, and the second housing 42 and the base assembly 60 cooperate to form a receiving cavity 70.

[0048] The second housing 42 and / or the third housing 43 are threadedly engaged with the base assembly 60. That is to say, the second housing 42 is threadedly engaged with the base assembly 60, or the third housing 43 is threadedly engaged with the base assembly 60, or both the second housing 42 and the third housing 43 are threadedly engaged with the base assembly 60. In this way, the liquid storage assembly 40 and the base assembly 60 can not only be relatively fixed by threaded engagement, but also be disassembled by rotating relative to each other to allow the atomization assembly 50 to be taken out separately.

[0049] Figure 4 The situation where the second housing 42 is threadedly engaged with the base assembly 60 is shown, which is only for example and not limited thereby. Of course, in other embodiments of the present application, the liquid storage assembly 40 and the base assembly 60 can also be detachably connected by other means, such as snap connection, magnetic attraction, etc., which are not limited herein.

[0050] And, Figure 4Also shown is the detachable setting manner of the first housing 51 of the atomization assembly 50 in the accommodation cavity 70. Specifically, one end of the first housing 51 abuts against the second housing 42 of the liquid storage assembly 40, and the other end of the first housing 51 abuts against the base assembly 60. The first housing 51 is not fixedly connected to the second housing 42 and the base assembly 60, but only in contact. Therefore, after the liquid storage assembly 40 and the base assembly 60 are disassembled from each other, the atomization assembly 50 can naturally be taken out separately.

[0051] Of course, in other embodiments of the present application, the detachable manner of the first housing 51 with the second housing 42 and the base assembly 60 can also be the above-mentioned screw fitting, snap fit, magnetic attraction, etc., which are not limited herein.

[0052] Furthermore, the liquid storage assembly 40 further includes a mouthpiece member 44. At least part of the air outlet channel 45 is provided in the mouthpiece member 44, and the air outlet channel 45 communicates with the atomization cavity 53. The aerosol formed in the atomization cavity 53 is output to the user through the air outlet channel 45 for the user to inhale.

[0053] The mouthpiece member 44 is threadedly engaged with the second housing 42 and / or the third housing 43. That is to say, the mouthpiece member 44 is threadedly engaged with the second housing 42, or the mouthpiece member 44 is threadedly engaged with the third housing 43, or the mouthpiece member 44 is threadedly engaged with the second housing 42 and the third housing 43 respectively. In this way, not only can the mouthpiece member 44 and the second housing 42 and / or the third housing 43 be relatively fixed by screw fitting, but also can be disassembled by rotating relative to each other to open the liquid storage cavity 41 between the second housing 42 and the third housing 43, allowing the user to replenish the aerosol matrix in the liquid storage cavity 41, that is, the liquid storage cavity 41 in this embodiment adopts an open design.

[0054] Figure 4 The situation where the mouthpiece member 44 is threadedly engaged with the second housing 42 is shown, only for example, and is not limited thereby. Of course, in other embodiments of the present application, the mouthpiece member 44 and the second housing 42 and / or the third housing 43 can also be detachably connected by other means, such as snap fit, magnetic attraction, etc., which are not limited herein.

[0055] It should be noted that Figure 4 It is shown that at least part of the air outlet channel 45 is also provided in the second housing 42, and the air outlet channel 45 in the mouthpiece member 44 communicates with the atomization cavity 53 in the first housing 51 through the air outlet channel 45 in the second housing 42.

[0056] Please continue to refer to Figures 3 to 5。In one embodiment, the first housing 51 includes a metal sleeve 513 and a support base 514. The metal sleeve 513 and the support base 514 are butted to form an atomization chamber 53. Further, the metal sleeve 513 can be assembled to the support base 514 by means of riveting or the like. The air exchange channel 512 is located on the outer periphery of the support base 514. The atomization assembly 50 further includes an elastic fixing member 54, and the atomization core 52 is fixed in the metal sleeve 513 by the elastic fixing member 54. Further, the number of the elastic fixing members 54 can be two, and both ends of the atomization core 52 are respectively assembled with the metal sleeve 513 through an elastic fixing member 54.

[0057] Optionally, the elastic fixing member 54 can be made of materials such as silica gel, which is not limited herein.

[0058] Further, the atomization assembly 50 further includes a first conduction electrode 55, a second conduction electrode 56 and an electrode post 57. The second housing 42 of the liquid storage assembly 40 is made of a conductive material. One end of the atomization core 52 is electrically connected to the metal sleeve 513 through the first conduction electrode 55, and is electrically connected to the second housing 42 through the metal sleeve 513. The electrode post 57 is disposed in the support base 514, and the other end of the atomization core 52 is electrically connected to the electrode post 57 through the second conduction electrode 56.

[0059] The base assembly 60 includes a connection seat 61, a fourth housing 62 and a connection electrode 63, and the connection seat 61 is embedded in the fourth housing 62. The connection electrode 63 is disposed on the connection seat 61, and they are insulated from each other. For example, insulation between the connection electrode 63 and the connection seat 61 can be achieved through silica gel or the like. The connection seat 61 is detachably connected to the second housing 42 of the liquid storage assembly 40, for example, through the above-mentioned screw fit connection or the like. The electrode post 57 of the atomization assembly 50 is electrically connected to the connection electrode 63. The connection seat 61 is also made of a conductive material, and the connection seat 61 is also electrically connected to the second housing 42.

[0060] The connection electrode 63 and the connection seat 61 are respectively used for electrically connecting the power supply assembly. Specifically, the connection electrode 63 is used for electrically connecting one of the positive electrode and the negative electrode of the power supply assembly, and the connection seat 61 is used for electrically connecting the other, so that the atomization core 52 is connected to the positive electrode and the negative electrode of the power supply assembly to control the atomization of the aerosol matrix by the atomization core 52 through the power supply assembly.

[0061] Please refer to Figures 4 to 6 , Figure 6 which is a schematic structural diagram of an embodiment of the support base of the present application.

[0062] In one embodiment, the ventilation channel 512 includes an inlet channel 515, a main channel (including a first sub-channel and a second sub-channel described below), and an outlet channel 516 that are connected in sequence. The main channel is located at the periphery of the first housing 51, and the main channel is connected to the outside of the atomizer 30 through the inlet channel 515, and the main channel is connected to the liquid storage chamber 41 through the outlet channel 516.

[0063] Furthermore, the inlet channel 515 is connected to the atomizing chamber 53, so as to be connected to the outside of the atomizer 30 through the atomizing chamber 53. That is to say, the ventilation channel 512 of this embodiment is connected to the outside of the atomizer 30 by connecting to the atomizing chamber 53. In this way, the aerosol matrix leaking into the ventilation channel 512 will not directly leak to the outside of the atomizer 30, but will flow into the atomizing chamber 53, which can reduce the risk of the aerosol matrix leaking to the outside of the atomizer 30, thereby avoiding affecting the user's experience.

[0064] Specifically, the inlet channel 515 is arranged along the second direction (eg Figure 4 The outlet channel 516 extends along the axial direction of the first shell 51 and also extends toward the liquid storage chamber 41, thereby being connected to the liquid storage chamber 41.

[0065] Specifically, the ventilation channel 512 is located at the support seat 514 of the first shell 51, and the liquid storage chamber 41 is located on the side of the support seat 514 facing the metal sleeve 513. The main channel is located at the outer periphery of the support seat 514, the inlet channel 515 penetrates the support seat 514 along the second direction, and the outlet channel 516 is located at the support seat 514 and extends toward the metal sleeve 513, thereby connecting to the liquid storage chamber 41.

[0066] See also Figures 4 to 6 In one embodiment, the base assembly 60 is provided with a first air inlet 64 connected to the outside. The first housing 51 is provided with a second air inlet 517, and the first air inlet 64 is connected to the atomization chamber 53 through the second air inlet 517. Figure 4 As shown by the dotted arrow, when the user inhales, the external gas enters the atomizing chamber 53 through the first air inlet 64 and the second air inlet 517 in turn, so as to carry the aerosol formed in the atomizing chamber 53 to the user; and part of the gas in the atomizing chamber 53 enters the ventilation channel 512 through the inlet channel 515 on the side wall of the first shell 51, and then reaches the liquid storage chamber 41 through the outlet channel 516, so as to supplement the air pressure in the liquid storage chamber 41, thereby ensuring that the aerosol matrix in the liquid storage chamber 41 can be smoothly transmitted to the atomizing core 52, and the aerosol matrix at the atomizing core 52 can be replenished in time, thereby reducing the risk of dry burning and overheating of the atomizing core 52, and avoiding damage to the atomizing core 52, the generation of burnt smell, and the generation of harmful substances as much as possible.

[0067] Further, the electrode column 57 of the atomization assembly 50 is a hollow columnar structure, and the space inside the electrode column 57 communicates with the atomization core 52. An air inlet is also provided on the side wall of the electrode column 57. The air flow entering from the second air inlet 517 enters the space inside the electrode column 57 through the air inlet on the side wall of the electrode column 57, and is transmitted to the atomization core 52 through the space inside the electrode column 57 to carry the aerosol formed at the atomization core 52 for output.

[0068] In one embodiment, as Figure 5 shown, the outlet channel 516 is adjacent to the liquid inlet 511 on the first housing 51. In this way, the bubbles generated due to air exchange at the outlet channel 516 can easily be discharged to the outside of the air exchange channel 512 through the liquid inlet 511, and as much as possible, the bubbles are prevented from adhering to the outlet channel 516 and affecting the air exchange effect.

[0069] In one embodiment, the inlet channel 515 and the outlet channel 516 are respectively located at different positions in the axial direction of the first housing 51. To connect the inlet channel 515 and the outlet channel 516, the main channel includes a first sub-channel (including the first sub-channel 5181, the first sub-channel 5182, and the first sub-channel 5183 described below) and a second sub-channel (including the second sub-channel 5191 and the second sub-channel 5192 described below). The first sub-channel extends along the circumferential direction of the first housing 51, and the second sub-channel extends along the axial direction of the first housing 51. The inlet channel 515 and the outlet channel 516 are connected through the first sub-channel and the second sub-channel.

[0070] In an exemplary embodiment, the main channel includes a first sub-channel 5181 and a second sub-channel 5191, that is, the number of the first sub-channels and the number of the second sub-channels in this embodiment are both one. The inlet channel 515 is sequentially connected to the outlet channel 516 through the first sub-channel 5181 and the second sub-channel 5191. The first sub-channel 5181 has a complete annular structure. In the circumferential direction of the first housing 51, the central angle corresponding to the area between the inlet channel 515 and the outlet channel 516 is 180°, and the central angle corresponding to the area between the inlet channel 515 and the second sub-channel 5191 is also 180°.

[0071] In the above manner, the air flow entering the air exchange channel 512 from the inlet channel 515 is transmitted along the first sub-channel 5181 (i.e., along the circumferential direction of the first housing 51) to the second sub-channel 5191, and then is transmitted along the second sub-channel 5191 (i.e., along the axial direction of the first housing 51) to the outlet channel 516, and then is output from the outlet channel 516 to the liquid storage cavity 41 to supplement the air pressure in the liquid storage cavity 41. The air flow direction is as shown by the dashed arrows in Figure 5 and Figure 6 the figure.

[0072] Please refer to Figure 7and Figure 8 , Figure 7 is a structural schematic diagram of another embodiment of the support seat of the present application, Figure 8 yes Figure 7 A schematic structural diagram of the support seat from another perspective is shown.

[0073] In another exemplary embodiment, the main channel includes a first sub-channel 5182, a first sub-channel 5183 and a second sub-channel 5192, that is, the number of the first sub-channels in this embodiment is two, and the number of the second sub-channel is one. The inlet channel 515 is connected to the outlet channel 516 through the first sub-channel 5182, the second sub-channel 5192 and the first sub-channel 5183 in sequence. The first sub-channel 5182 and the first sub-channel 5183 are both complete annular structures. In the circumference of the first shell (i.e., the support seat 514), the inlet channel 515 and the outlet channel 516 are in the same position, and the central angle corresponding to the area between the inlet channel 515 and the second sub-channel 5192 is 180°, and the central angle corresponding to the area between the outlet channel 516 and the second sub-channel 5192 is also 180°.

[0074] In the above manner, the airflow entering the ventilation channel from the inlet channel 515 is first transmitted along the first sub-channel 5182 (i.e., along the circumferential direction of the first shell) to the second sub-channel 5192, then along the second sub-channel 5192 (i.e., along the axial direction of the first shell) to the first sub-channel 5183, and then along the first sub-channel 5183 (i.e., along the circumferential direction of the first shell) to the outlet channel 516, and then output from the outlet channel 516 to the liquid storage chamber to supplement the air pressure in the liquid storage chamber. The airflow direction is as follows: Figure 7 and Figure 8 Indicated by the dashed arrow.

[0075] For further information, please refer to Figures 4 to 6 The length of the ventilation channel 512 can be 15mm to 25mm, that is, the total length of the inlet channel 515, the main channel and the outlet channel 516 is 15mm to 25mm, for example, 15mm, 15.8mm, 16.5mm, 17.4mm, 18.6mm, 19.3mm, 20.7mm, 21.4mm, 22.1mm, 23.5mm, 24.2mm, 25mm, etc.

[0076] Through the above method, the ventilation channel 512 has a sufficient length, which can prevent the aerosol matrix in the liquid storage chamber 41 from leaking from the ventilation channel 512 as much as possible, and avoid affecting the user's experience due to the leakage of the aerosol matrix. Therefore, this embodiment can reduce the risk of leakage of the aerosol matrix in the liquid storage chamber 41, which is conducive to improving the user's experience.

[0077] Further, a plurality of fins 80 are disposed on the outer periphery of the first shell 51 , and the plurality of fins 80 are distributed at intervals. Specifically, the plurality of fins 80 may be distributed at intervals along the axial direction of the first shell 51 , and / or the plurality of fins 80 may be distributed at intervals along the circumferential direction of the first shell 51 . Figure 5 and Figure 6 The situation in which some of the fins 80 are distributed at intervals along the axial direction of the first shell 51 and the remaining fins 80 are distributed at intervals along the circumferential direction of the first shell 51 is shown only for example and is not intended to be limiting.

[0078] Furthermore, the gaps between adjacent fins 80 form at least a main channel and an outlet channel 516, that is, at least a first sub-channel (including the first sub-channel 5181, the first sub-channel 5182, and the first sub-channel 5183 described above), a second sub-channel (including the second sub-channel 5191 and the second sub-channel 5192 described above), and an outlet channel 516. Specifically, the gaps between the fins 80 spaced apart along the axial direction of the first housing 51 form the first sub-channel, and the gaps between the fins 80 spaced apart along the circumferential direction of the first housing 51 form the second sub-channel and the outlet channel 516. The inlet channel 515 is located at the bottom of the gap where the first sub-channel is located.

[0079] The gaps between adjacent fins 80 also form a liquid storage channel 81, wherein the liquid storage channel 81 is used to store the aerosol matrix leaking to the periphery of the first shell 51, which can reduce the risk of aerosol matrix leakage and avoid affecting the user's experience due to aerosol matrix leakage as much as possible. Figure 5 and Figure 6 It can be seen that, except for the main channel and the outlet channel 516, all other gaps are liquid storage channels 81, which can maximize the number of liquid storage channels 81 and thus minimize the risk of aerosol matrix leakage.

[0080] In summary, the atomizer provided in the present application and the atomizer assembly and electronic atomizer device used therein. The liquid storage assembly and the base assembly of the atomizer are detachably connected, and the first shell of the atomizer assembly is detachably arranged in the accommodating cavity formed by the liquid storage assembly and the base assembly. This means that the atomizer assembly of this embodiment adopts a detachable design, which can be removed from the atomizer for replacement. When the atomizer assembly is damaged, the user does not have to abandon the entire atomizer, which can be convenient for the user to use.

[0081] In addition, the atomizer of the present application is provided with a ventilation channel, which is connected to the liquid storage chamber and also connected to the outside of the atomizer. When the user inhales, the airflow outside the atomizer reaches the liquid storage chamber through the ventilation channel to supplement the air pressure in the liquid storage chamber. Among them, the ventilation channel is arranged in the first shell, that is, the ventilation channel is independent of the atomizer core, and the ventilation channel will not hinder the transmission of the aerosol matrix in the liquid storage chamber to the atomizer core, and the aerosol matrix at the atomizer core can be replenished in time, thereby reducing the risk of dry burning and overheating of the atomizer core, and avoiding problems such as damage to the atomizer core, the generation of burnt smell, and the generation of harmful substances as much as possible.

[0082] The first shell provided with a ventilation channel in the present application adopts an independent component design and can be used in different atomization components and electronic atomization devices without the need for additional development and design of a ventilation structure, which is conducive to shortening the product development cycle and reducing the product production cost.
