Obviously, the described embodiments are only a part of the embodiments of the present application, but not all the embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0030] In addition, the description of "first", "second", etc. in the present application is only for the purpose of description, and cannot be understood as indicating or implying the relative importance of the indicated technical features or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first", "second" can explicitly or implicitly include at least one of the features. In addition, the technical solutions of each embodiment can be combined with each other, but it must be based on the realization of a person of ordinary skill in the art, and when the combination of technical solutions contradicts each other or cannot be realized, it should be considered that the combination of technical solutions does not exist and is not within the scope of protection claimed by the present application.

[0031] In one embodiment, as shown in Figures 1 to 3 The electronic atomization device 1 provided by the embodiment of the present application includes a shell assembly 100 and at least two atomization assemblies 200, wherein the shell assembly 100 specifically can include an inner shell 110 with an airflow passage 111 and a base 120. The airflow passage 111 includes an airflow outlet section 1111 and at least two atomization passage sections 1112. The at least two atomization passage sections 1112 are arranged one by one corresponding to the at least two atomization assemblies 200. One end of all the atomization passage sections 1112 converges and communicates at the airflow outlet section 1111, and one atomization assembly 200 is arranged at the end of each atomization passage section 1112 away from the airflow outlet section 1111. The base 120 is arranged at the end of the inner shell 110 away from the airflow outlet section 1111. The inner wall of the inner shell 110, the base 120, and the outer wall of all the atomization passage sections 1112 form a liquid storage cavity 112. All the atomization assemblies 200 are also in liquid communication with the liquid storage cavity 112, so as to heat and atomize the liquid in the liquid storage cavity 112 to form an aerosol.

[0032] It can be understood that the electronic atomization device 1 mentioned in the embodiments of the present application is mainly applied to the atomization operation of a specific liquid, so as to convert the stored specific liquid (which can be specifically an atomization liquid such as tobacco tar) into aerosol for the user to inhale. Each atomization assembly 200 mentioned above is arranged at the end of the atomization channel segment 1112 away from the airflow outlet segment 1111, which means that the aerosol generated by each atomization assembly 200 during atomization can enter the corresponding atomization channel segment 1112 through the end of the atomization channel segment 1112 away from the airflow outlet segment 1111. All the atomization assemblies mentioned above are also in liquid communication with the liquid storage cavity 112, which means that the number of liquid outlets of the liquid storage cavity 112 corresponds to the arrangement of each atomization assembly 200, so that the liquid in the liquid storage cavity 112 can flow to each atomization assembly 200 through the liquid outlets, so that each atomization assembly 200 can be kept in a wet or semi-wet state. In this way, the problem of liquid flow lag of part of the product at the beginning of use, which affects the atomization effect of the corresponding atomization assembly 200, can be avoided.

[0033] In addition, in order to ensure the sealing performance of the liquid storage cavity 112, a sealing ring 130 is arranged between the connection between the base 120 and the end of the inner shell 110 away from the airflow outlet segment 1111, which is preferably in the form of an O-ring, so as to further ensure the sealing performance of the liquid storage cavity 112.

[0034] In this way, the electronic atomization device 1 provided by the embodiments of the present application can be arranged with multiple atomization assemblies 200 (i.e. multiple heating bodies) while ensuring that the remaining liquid in each liquid storage cavity 112 is uniform by arranging at least two atomization assemblies 200 in liquid communication with a single liquid storage cavity 112, thereby avoiding the problems of waste of liquid in the liquid storage cavity 112 or burning of the heating body, and improving the user experience. At the same time, after each atomization assembly 200 is independently atomized through the corresponding atomization channel segment 1112, the aerosol is combined and sprayed through the airflow outlet segment 1111, which can avoid the problems of too much air mixed in the large air duct due to the simultaneous arrangement of multiple atomization assemblies 200 in the air duct, resulting in excessive loss of aerosol and affecting the taste in the mouth. In addition, the problems of inconsistent taste in the mouth due to the mutual influence of different atomization assemblies 200 caused by uneven heat of different atomization assemblies 200 can also be avoided, that is, the aerosol heat of each atomization channel segment 1112 can be balanced after being atomized through the atomization channel segment 1112, and the consistency of the taste in the mouth can be ensured when the aerosol is delivered to the airflow outlet segment 1111, so as to improve the taste in the mouth.

[0035] In some examples, such as Figures 1 to 3 As shown, at least two atomizing channel sections 1112 may specifically include a first atomizing channel section 11 and a second atomizing channel section 12, the first atomizing channel section 11 and the second atomizing channel section 12 are spaced apart and arranged side by side, and one end of the first atomizing channel section 11 and one end of the second atomizing channel section 12 are both in communication with the airflow outlet section 1111. At least two atomizing assemblies 200 include a first atomizing assembly 210 and a second atomizing assembly 220, the first atomizing assembly 21 being arranged in the base 120, and being in gas communication with one end of the first atomizing channel section 11 away from the airflow outlet section 1111, and being in liquid communication with the liquid storage chamber 112. The second atomizing assembly 220 is arranged in the base 120, and being in gas communication with one end of the second atomizing channel section 12 away from the airflow outlet section 1111, and being in liquid communication with the liquid storage chamber 112. In this way, through the above-mentioned structural setting, the electronic atomization device can form a structural setting of a dual atomization component 200 (i.e., a multi-heating element), while the first atomization component 210 and the second atomization component 220 are both connected to the liquid of the same single-set liquid storage chamber 112, ensuring that there will be no uneven remaining liquid in each liquid storage chamber 112 due to the setting of multiple liquid storage chambers 112, thereby being able to avoid as much as possible the waste of liquid in the liquid storage chamber 112 or the burnt smell caused by the dry burning of the heating element, so as to enhance the user experience. At the same time, when the first atomization component 210 and the second atomization component 220 are performing atomization work at the same time, the atomization is performed separately by the first atomization channel section 11 and the second atomization channel section 12 and then merged through the airflow outlet section 1111, which can effectively ensure the balance of the aerosol heat of the first atomization channel section 11 and the second atomization channel section 12, and achieve the consistency of the oral taste delivered to the airflow outlet section 1111.

[0036] In some examples, such as Figures 1 to 3As shown, the base 120 is provided with a first atomization compartment (not labeled in the figure) for accommodating the first atomization assembly 200 and a second atomization compartment (not labeled in the figure) for accommodating the second atomization assembly 300. The first atomization compartment is in communication with one end of the first atomization channel segment 11 away from the airflow outlet segment 1111, and the inner wall of the first atomization compartment is provided with a first liquid outlet (not shown) in communication with the liquid storage cavity 112. The second atomization compartment is in communication with one end of the second atomization channel segment 12 away from the airflow outlet segment 1111, and the inner wall of the second atomization compartment is provided with a second liquid outlet (not shown) in communication with the liquid storage cavity 112. In this way, when the liquid in the liquid storage cavity 112 flows to the first atomization compartment through the first liquid outlet, the first atomization assembly 210 in the first atomization compartment can heat and atomize the liquid to generate aerosols, which enter the first atomization channel segment 11 through one end of the first atomization channel segment 11 away from the airflow outlet segment 1111, and then flow into the airflow outlet segment 1111 to be discharged outward. When the liquid in the liquid storage cavity 112 flows to the second atomization compartment through the second liquid outlet, the second atomization assembly 220 in the second atomization compartment can heat and atomize the liquid to generate aerosols, which enter the second atomization channel segment 12 through one end of the second atomization channel segment 12 away from the airflow outlet segment 1111, and then flow into the airflow outlet segment 1111 to be discharged outward.

[0037] It can be understood that, in order to facilitate the accommodation of the first atomization assembly 210 in the first atomization compartment and the accommodation of the second atomization assembly 220 in the second atomization compartment, the base 120 can specifically consist of two parts, i.e., an atomizer support 121 and a battery support 122. One end of the atomizer support 121 is arranged at the end of the inner shell 110 away from the airflow outlet segment 1111, so as to form a single liquid storage cavity 112 in the interior of the inner shell 110. The other end of the atomizer support 121 is detachably connected (specifically, a buckle connection realized by a buckle structure) with the battery support 122, so as to form the corresponding first atomization compartment and second atomization compartment in cooperation with the battery support 122.

[0038] In some examples, as Figures 1 to 3As shown, a heat insulating layer 300 is provided at the interval between the first atomizing channel section 11 and the second atomizing channel section 12. The extension direction of the heat insulating layer 300, the extension direction of the first atomizing channel section 11, and the extension direction of the second atomizing channel section 12 are all the same, and the first atomizing channel section 11 and the second atomizing channel section 12 are symmetrically arranged on both sides of the heat insulating layer 300. In this way, through the above-mentioned structural arrangement, the symmetrical arrangement of the first atomizing channel section 11 and the second atomizing channel section 12 can ensure the consistency of the air paths of the first atomizing channel section 11 and the second atomizing channel section 12, that is, the same air flow structure and air flow path, so as to ensure the consistency of the taste after the aerosols in the two merge. The arrangement of the heat insulating layer 300 can also prevent the heat in the first atomizing channel section 11 and the heat in the second atomizing channel section 12 from affecting each other.

[0039] It is understandable that the heat insulation layer 300 can be made of a material with good heat insulation effect, and its extension length is not less than the extension length of the first atomization channel section 11 or the second atomization channel section 12 to ensure its heat insulation effect between the two.

[0040] In some examples, such as Figures 1 to 3 As shown, the first atomizing assembly 210 and the second atomizing assembly 220 are arranged in parallel, and the first atomizing assembly 210 and the second atomizing assembly 220 are symmetrically arranged on both sides of the extension line of the heat insulation layer 300 . In this way, the above-mentioned structural setting can be used to enable the electronic atomization device 1 to specifically form a dual atomization component 200 (i.e., dual heating element) working mode. In the dual atomization component 200 (i.e., dual heating element) working mode, on the one hand, it can alternately perform atomization work through the first atomization component 210 and the second atomization component 220 to effectively reduce the high-power operation time of a single atomization component 200 (i.e., the first atomization component 210 or the second atomization component 220), so as to avoid the single atomization component 200 from having problems such as heating volume carbonization and local blackening due to long-term high-power operation. On the other hand, the first atomization component 210 and the second atomization component 220 can simultaneously perform atomization work to ensure the atomization effect of the single atomization component 200 (i.e., the first atomization component 210 or the second atomization component 220) under low power and high power conditions (i.e., it can provide sufficient aerosol and achieve a rich taste), and can also avoid the single atomization component 200 from having problems such as heating volume carbonization and local blackening due to long-term high-power operation.

[0041] It is understandable that, in order to realize the parallel arrangement of the first atomization assembly 210 and the second atomization assembly 220, the electronic atomization device 1 specifically further includes an electrode column assembly 400, which includes a first electrode column 410, a second electrode column 420, and a third electrode column 430. The first electrode column 410 is electrically connected to one electrode of the first atomization assembly 210, the second electrode column 420 is electrically connected to one electrode of the second atomization assembly 220, and the third electrode column 430 is electrically connected to the other electrode of the first atomization assembly 210 and the other electrode of the second atomization assembly 220. In this way, through the above-mentioned structural arrangement, a common pole design is adopted when the first atomization assembly 200 and the second atomization assembly 300 are electrically connected, so as to better realize the parallel arrangement between the two.

[0042] In some examples, such as Figures 1 to 3 As shown, each atomization component 200 may specifically include a liquid-conducting cotton 21 and a heating element 22. The liquid-conducting cotton 21 is located at one end of the corresponding atomization channel section 1112 away from the airflow outlet section 1111, and blocks the liquid outlet of the liquid storage chamber 112. The heating element 22 is arranged on the liquid-conducting cotton 21. In this way, through the above-mentioned structural arrangement, the liquid coming out of the liquid storage chamber 112 through the liquid outlet can be fully infiltrated into the heating element 22 by the capillary action of the liquid-conducting cotton 21, so as to ensure that the heating element 22 fully atomizes it. Furthermore, the liquid-conducting cotton 21 is a planar liquid-conducting cotton, and the heating elements 22 are all planar heating elements. The liquid-conducting cotton 21 is attached to the surface of the heating element 22 on one side parallel to the extension direction of the atomization channel section 1112. In this way, through the above-mentioned structural arrangement, the heating and atomization effect of the heating element 22 can be ensured by ensuring sufficient contact between the heating element 22 and the liquid-conducting cotton 21.

[0043] It can be understood that the flat liquid guiding cotton mentioned in the example specifically refers to the liquid guiding cotton in a sheet structure, which has a large-area surface parallel to the extension direction of the atomization channel segment 1112. The flat heating body mentioned in the example specifically refers to the heating body as a whole in a sheet structure, which has a large-area surface parallel to the extension direction of the atomization channel segment 1112, including but not limited to a single-piece structure and a multi-fin structure (the surfaces of the multiple fins parallel to the extension direction of the atomization channel segment 1112 are located on the same horizontal plane). In addition, the first atomization chamber and the second atomization chamber mentioned in the above example can be in communication with each other, at this time, the liquid guiding cotton 21 of the first atomization assembly 210 and the liquid guiding cotton 21 of the second atomization assembly 220 are in an integrated structure, the first electrode column 410 can be electrically connected to one electrode of the heating body 22 of the first atomization assembly 210, the second electrode column 420 can be electrically connected to one electrode of the heating body 22 of the second atomization assembly 220, and the third electrode column 430 is electrically connected to the other electrode of the heating body 22 of the first atomization assembly 210 and the other electrode of the heating body 22 of the second atomization assembly 220, respectively. In this way, through the above structural arrangement, the electrical connection between the first atomization assembly 210 and the second atomization assembly 220 and the electrode column assembly 400 can be realized, on the one hand, the first atomization assembly 210 and the second atomization assembly 220 share the same liquid guiding cotton 21, and on the other hand, the heating body 22 of the first atomization assembly 210 and the heating body 22 of the second atomization assembly 220 adopt a common electrode design when electrically connected. All the above can make the overall layout of the electronic atomization device 1 more reasonable, effectively simplify the overall structure of the electronic atomization device 1, and save the production cost.

[0044] In addition, the electrical connection between the electrode column and the electrode mentioned in the above example can be that the electrode is fixed on the corresponding electrode column by spot welding structure to realize the electrical connection between the two. The communication between the first atomization chamber and the second atomization chamber mentioned in the example can be that the joint between the first atomization chamber and the second atomization chamber is completely opened, so that they are essentially the same atomization chamber. At this time, in order to fix the first atomization assembly 210 and the second atomization assembly 220 in the atomization chamber and ensure that the first atomization assembly 210 and the second atomization assembly 220 do not displace in the atomization chamber during use, a corresponding mounting bracket 123 is arranged in the atomization chamber, the mounting bracket 123 can be provided with two mounting grooves arranged side by side to respectively embed the heating body 22 of the first atomization assembly 210 and the heating body 22 of the second atomization assembly 220. At this time, the liquid guiding cotton 21 of the first atomization assembly 210 and the liquid guiding cotton 21 of the second atomization assembly 220 are arranged at the groove openings of the two mounting grooves to respectively abut against the corresponding heating body 22 and the corresponding cavity wall of the atomization chamber.

[0045] In some examples, as Figures 1 to 3As shown, the electronic atomization device 1 further comprises a control assembly 500 and a battery assembly 600, which are respectively arranged on the side of the base 120 away from the inner shell 110, and the control assembly 500 is electrically connected with the electrode column assembly 400 and the battery assembly 600. In this way, through the above structural arrangement, when the user uses the electronic atomization device 1, the first atomization assembly 210 and the second atomization assembly 220 can be alternately or simultaneously controlled to perform atomization work under the control of the control assembly 500 and the power supply of the battery assembly 600.

[0046] It can be understood that the control assembly 500 mentioned in the example can specifically include a PCBA control mainboard 510 and a control button 520, which are arranged on the battery support 122 together with the battery assembly 600.

[0047] In some examples, as Figures 1 to 3 shown, the base 120 is further provided with an air inlet channel communicating with the external environment, and the end of the air inlet channel away from the air inlet communicates with the first atomization chamber and the second atomization chamber. The electronic atomization device 1 further comprises a microphone switch 700 arranged in the air inlet channel. In this way, through the above structural arrangement, when the user starts the electronic atomization device 1, the user can control the first atomization assembly 210 and / or the second atomization assembly 220 to perform corresponding atomization work by triggering the microphone switch 700 in the air inlet channel through the user's each time sucking the electronic atomization device 1 at the mouth part (the position where the air flow outlet section 1111 is located), and at the same time, the external airflow entering the air inlet channel can flow in the direction indicated by the arrow in Figure 1 , so that the aerosol generated by the first atomization assembly 210 and / or the second atomization assembly 220 can enter the user's oral cavity through the air flow outlet section 1111 to realize corresponding suction operation.

[0048] It can be understood that the microphone switch 700 mentioned in the example can be arranged in the air inlet channel through a switch support.

[0049] In addition, in order to realize the surrounding protection of the structures such as the inner shell 110, the base 120, the control assembly 500, and the battery assembly 600 of the electronic atomization device 1, the shell assembly 100 mentioned above further comprises a first shell 140 and a second shell 150, which are detachably and tightly connected to form an installation cavity for installing and fixing the structures such as the inner shell 110, the base 120, the control assembly 500, and the battery assembly 600 mentioned above.

[0050] In one embodiment, as Figure 4As shown, the embodiments of the present application also provide a control method of the electronic atomization device, which can specifically include the following steps:

[0051] Step S110: If both the first atomization assembly and the second atomization assembly are in the normal state, the first atomization assembly and the second atomization assembly are controlled to alternately perform the atomization work when the user uses the electronic atomization device.

[0052] Step S120: If the first atomization assembly is in the abnormal state, the second atomization assembly is controlled to perform the atomization work when the user uses the electronic atomization device.

[0053] Step S130: If the second atomization assembly is in the abnormal state, the first atomization assembly is controlled to perform the atomization work when the user uses the electronic atomization device.

[0054] It can be understood that the control method of the embodiments of the present method is specifically applied to the electronic atomization device in the above embodiments, including but not limited to the electronic atomization device with double atomization assemblies, that is, although the method steps are described with respect to the electronic atomization device with double atomization assemblies, they are also applicable to the electronic atomization device with more than two atomization assemblies. The normal state mentioned in the above method steps is that the corresponding atomization assembly is not damaged and can perform normal atomization work, so the abnormal state mentioned in the above method steps is that the corresponding atomization assembly is damaged and can no longer perform normal atomization work.

[0055] In this way, through the control of the above method steps, on the one hand, when both the first atomization assembly and the second atomization assembly are in the normal state, the first atomization assembly and the second atomization assembly are alternately controlled to perform the atomization work, which can effectively reduce the high-power running time of a single atomization assembly to avoid problems such as carbon deposition and local blackening of the heating body caused by long-time high-power running of a single atomization assembly, that is, it can ensure that the atomization assembly has no carbon deposition abnormality for a longer time and improve the suction quality in the middle and later stages of suction to ensure the consistency of the taste in the front, middle and rear stages. On the other hand, when any one of the first atomization assembly and the second atomization assembly is in the abnormal state, the other one that does not have an abnormality is controlled to perform the atomization work, which can ensure that the electronic atomization device can work normally to ensure that the electronic atomization device will not be scrapped prematurely due to the abnormality of one of them, thereby greatly improving the service life of the electronic atomization device.

[0056] In one embodiment, as shown in FIG. 5, the embodiments of the present application also provide a control method of the electronic atomization device, which can specifically include the following steps:

[0057] Step S210: According to the first control instruction input by the user, the electronic atomization device is controlled to enter the first working mode, so that both the first atomization assembly and the second atomization assembly are in a low-power working state.

[0058] Step S220: According to the second control instruction input by the user, the electronic atomization device is controlled to enter a second working mode, so that both the first atomization component and the second atomization component are in a high-power working state.

[0059] Step S230: According to the third control instruction input by the user, the electronic atomization device is controlled to enter a third working mode, so that the first atomization component is in a low-power working state and the second atomization component is in a high-power working state, or the first atomization component is in a high-power working state and the second atomization component is in a low-power working state.

[0060] It can be understood that the control method of the method embodiment is specifically applied to the electronic atomization device in the above embodiments, including but not limited to the electronic atomization device with double atomization components, that is, although the method steps are described with respect to the electronic atomization device with double atomization components, they are also applicable to the electronic atomization device with more than two atomization components. The input and switching of the first control instruction, the second control instruction, and the third control instruction mentioned in the above method steps can be realized by using the control button mentioned in the above embodiments, that is, by different operations of the user on the control button.

[0061] In this way, through the control of the above method steps, on the one hand, the single atomization component (i.e., the first atomization component or the second atomization component) can ensure its atomization effect (i.e., can provide sufficient aerosol to achieve a rich taste) in the case of low power and high power, so as to avoid problems such as heating volume carbon and local blackening of the single atomization component due to long-time high-power operation, that is, to ensure that the atomization component has no carbon deposition anomaly for a longer time and improve the smoking quality in the middle and later stages of smoking, thereby providing a guarantee for the consistency of the front, middle, and rear stages of the taste. On the other hand, through the input of different control instructions, the first atomization component and the second atomization component can simultaneously perform atomization work through different state combinations, such as the ordinary mode in which both are in a low-power working state, the super-high burst mode in which both are in a high-power working state, and the high-burst mode in which one is in a high-power working state and the other is in a low-power working state, thereby greatly enriching the user's selection of the smoking mode and effectively improving the user's smoking experience.

[0062] The above only describes the preferred embodiments of the present application, and does not limit the patent scope of the present application. Any equivalent structural transformation made according to the contents of the present application specification and drawings, or direct / indirect application in other related technical fields within the inventive concept of the present application is included in the patent protection scope of the present application.
