TECHNICAL FIELD

[0003] The present application belongs to the technical field of atomization devices, and in particular relates to an atomizer and an electronic atomization device. BACKGROUND

[0004] An electronic atomization device is a device that generates aerosol for a user to use by heating and atomization. The electronic atomization device stores edible aerosol generating substrates in an atomizer and atomizes the aerosol generating substrates into edible aerosol. In order to meet the individual needs of users, the atomizer in the related art stores multiple aerosol generating substrates, for example, one or more of the boiling points, types, and flavors of the aerosol generating substrates are different, and it can be understood that the aerosol generating substrates are multiple aerosol generating substrates. The atomizer generates multiple aerosols and directs each aerosol out of the user's oral cavity for the user to consume.

[0005] However, the structure of the atomizer in the related art directly directs each aerosol out of the user's oral cavity, which causes the various aerosols to mix in the user's oral cavity, the mixing effect is poor, the taste of the various aerosols is layered, and the user's experience is affected.

[0006] The above content is only used to assist in understanding the technical solutions of the application and does not represent the acknowledgement of the above content as prior art. SUMMARY

[0007] To solve the problems in the related art, the present application provides an atomizer and an electronic atomization device to solve the technical problem of improving the mixing effect of the atomizer.

[0008] The embodiment of the present application provides a kind of atomizer, the atomizer includes: shell, inside being equipped with installation cavity and mixing cavity;Atomization component is provided with multiple, and all install in the installation cavity;The atomization component is used to generate aerosol, each the airflow passage for the aerosol flow circulation is equipped with inside the atomization component;Wherein, the mixing cavity one end is communicated with each airflow passage, to mix the aerosol exported by each airflow passage;The other end of the mixing cavity forms the outlet for the mixed aerosol to export the mixing cavity, and the outlet is used to communicate with the oral cavity of user.

[0009] In the embodiment of the present application, by setting the mixing cavity to communicate with each airflow passage, a mixing path is added to the path of the aerosol exported by the atomizer. The multiple aerosols are not directly introduced into the oral cavity for mixing. The multiple aerosols exported by the multiple airflow passages are first mixed in the mixing cavity and then exported outside the atomizer to enter the oral cavity of the user, reducing the taste stratification caused by the multiple aerosols being directly introduced into the oral cavity of the user for mixing and improving the user experience.

DETAILED DESCRIPTION

[0034] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work are within the scope of protection of the present application. In addition, the technical solutions of various embodiments can be combined with each other, but it must be based on the fact that a person of ordinary skill in the art can realize it, and when the combination of technical solutions appears contradictory or unachievable, 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.

[0035] It should be noted that if the present application involves directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present application, the directional indications are only used to explain the relative positional relationship, movement condition, etc. between the components in a certain posture, and if the certain posture changes, the directional indications will also change accordingly.

[0036] In addition, the meaning of "and / or" appearing throughout the text is that it includes three parallel solutions, for example, "A and / or B" includes A solution, or B solution, or A and B solutions at the same time.

[0037] The embodiment of the present application provides a kind of atomizer 10 and electronic atomization device, the electronic atomization device includes atomizer 10, and atomizer 10 is stored with aerosol generating substrate, and atomizer 10 is used to atomize aerosol generating substrate into aerosol, the aerosol generating substrate includes but is not limited to tobacco tar, chemical liquid, plant leaf juice, atomizer 10 can be applied to medical, beauty, electronic aerosolization etc.Situation.It needs to be explained that the application scenario type of the embodiment of the present application does not limit the structure of the atomizer 10 and electronic atomization device of the embodiment of the present application.

[0038] Referring to FIG. 1-4, the atomizer 10 includes a housing 1 and an atomization assembly 2, the housing 1 is provided with a mounting cavity 1011 (see FIG. 4) inside, and a plurality of atomization assemblies 2 are installed in the mounting cavity 1011. It can be understood that the number of atomization assemblies 2 is greater than or equal to two, and each atomization assembly 2 stores one type of aerosol generating substrate. For example, the atomization assembly 2 is provided with two, three, four, etc. Then, the types of aerosol generating substrates are adaptively provided with two, three, four, etc. The aerosol generating substrates in each atomization assembly 2 can only differ in boiling point, type, or taste. The aerosol generating substrates in each atomization assembly 2 can also differ in one or two parameters of boiling point, type, or taste. Regardless of the difference between the aerosol generating substrates in the above embodiments, each aerosol generating substrate can be regarded as "a plurality of aerosol generating substrates". For example, as shown in the schematic diagram of FIG. 3, two atomization assemblies 2 are provided in the mounting cavity 1011, which are a first atomization assembly 2a and a second atomization assembly 2b. Tobacco tar can be placed in the first atomization assembly 2a and the second atomization assembly 2b. Tobacco tar can also be placed in the first atomization assembly 2a, and plant leaf juice can be placed in the second atomization assembly 2b. Even if tobacco tar is placed in the first atomization assembly 2a and the second atomization assembly 2b, the taste and boiling point of the tobacco tar can be different and regarded as two types of aerosol generating substrates. For example, the components of the aerosol generating substrate are different, so the boiling point and taste of the aerosol generating substrate are different. Taking tobacco tar as an example, the boiling points of the components in the tobacco tar are as follows: propylene glycol 188.2°C, glycerol (glycerol) 290.9°C, nicotine 247°C, and the boiling point of common edible spices is 120-180°C. The boiling point of the tobacco tar prepared by mixing 50% propylene glycol and 50% glycerol is about 250°C.

[0039] It should be noted that if the aerosol contains a sweet additive, the boiling point, type and taste of the aerosol generating substrate will affect the proportion of large droplets (large droplet content / ingredient aerosol content) in the generated aerosol, thereby affecting the taste of the aerosol. In the case of a large proportion of large droplets, the aerosol tastes sweet; in the case of a small proportion of large droplets, the aerosol tastes fragrant. Therefore, regardless of the differences between various aerosol generating substrates based on the foregoing embodiments, various aerosol generating substrates will generate aerosols with various tastes, and the direct mixing of aerosols with various tastes in the oral cavity can easily produce a more obvious taste stratification, which may affect the taste of the food.

[0040] Referring to FIG. 3, each set of atomization assemblies 2 is provided with an airflow passage 21 for the flow of aerosol, and each airflow passage 21 collectively flows out multiple aerosols. The shell 1 is also provided with a mixing chamber 1012, one end of the mixing chamber 1012 being in communication with each airflow passage 21 to mix the aerosols discharged by each airflow passage 21. It should be noted that the "mixing chamber 1012 in communication with each airflow passage 21" does not mean that the wall surface of the shell 1 forming the mixing chamber 1012 is directly connected to the wall surface of the atomization assembly 2 forming the airflow passage 21. It can be that the wall surface of the shell 1 forming the mixing chamber 1012 is directly connected to the wall surface of the atomization assembly 2 forming the airflow passage 21, or it can be that the wall surface of the shell 1 forming the mixing chamber 1012 is indirectly connected to the wall surface of the atomization assembly 2 forming the airflow passage 21 through other components with cavities or passages, so that the mixing chamber 1012 communicates with each airflow passage 21 through other cavities or passages. For example, in the schematic diagram shown in FIG. 3, the mixing chamber 1012 communicates with each airflow passage 21 through multiple sub-air passages 121.

[0041] The other end of the mixing cavity 1012 forms an outlet 1013 for guiding the mixed aerosol out of the mixing cavity 1012, and the outlet 1013 is used to communicate with the oral cavity of the user. It can be understood that the "other end of the mixing cavity 1012" and the "one end of the mixing cavity 1012" are opposite ends of the mixing cavity 1012 in the aerosol flow direction, for example, in the embodiment shown in the schematic diagram of the present application, the one end of the mixing cavity 1012 is the lower end of the mixing cavity 1012, and the other end of the mixing cavity 1012 is the upper end of the mixing cavity 1012. The outlet 1013 communicates with the oral cavity of the user, so as to guide the mixed aerosol into the oral cavity of the user. However, it should be noted that the "outlet 1013 formed by the mixing cavity 1012 communicates with the oral cavity of the user" does not mean that the outlet 1013 formed by the mixing cavity 1012 is the outlet of the atomizer 10 arranged in the external environment, that is, the outlet 1013 formed by the mixing cavity 1012 can be on the outer edge of the atomizer 10, so that the mixing cavity 1012 is directly connected to the oral cavity of the user; the outlet 1013 formed by the mixing cavity 1012 can also not be on the outer edge of the atomizer 10, and the outlet 1013 formed by the mixing cavity 1012 can be located inside the atomizer 10, and the mixing cavity 1012 communicates with the oral cavity of the user through other channels or cavities. For example, in the schematic diagram shown in FIG. 12 of the present application, the other end of the mixing cavity 1012 is connected with a guiding cavity, one end of the guiding cavity 14 is connected with the mixing cavity 1012, and the other end of the guiding cavity 14 is located on the outer edge of the atomizer 10, thereby forming an outlet through which the atomizer 10 is directly connected to the oral cavity of the user.

[0042] The mixing cavity 1012 is arranged to increase the mixing path in the path of the atomizer 10 for guiding the aerosol out, and multiple aerosols are not guided into the oral cavity one by one for mixing, but are partially or completely mixed in the mixing cavity 1012 before being guided out of the atomizer 10 and into the oral cavity.

[0043] The embodiment of the present application provides a kind of atomizer 10, the atomizer 10 includes shell 1 and atomization component 2, the inside of shell 1 is equipped with installation cavity 1011 and mixing cavity 1012, atomization component 2 is provided with multiple, and all install in installation cavity 1011.Atomization component 2 is used to generate aerosol, the inside of each atomization component 2 is equipped with the airflow passage 21 for the flow of aerosol.The one end of mixing cavity 1012 is communicated with each airflow passage 21, to mix the aerosol exported by each airflow passage 21;The other end of mixing cavity 1012 forms the outlet 1013 for the mixed aerosol exported mixing cavity, outlet 1013 is used to communicate with the oral cavity of user.By being equipped with mixing cavity 1012 to communicate each airflow passage 21, so that multiple aerosols exported by multiple airflow passages 21 are mixed in mixing cavity 1012, realize the effect that atomizer 10 can mix multiple aerosols, to be able to meet the individualized needs of user, and multiple aerosols are mixed in mixing cavity 1012 again exported atomizer 10, into the oral cavity of user, reduce the taste stratification generated by multiple aerosols one by one imported into the oral cavity of user and then mixed, improve user experience.

[0044] Hereinafter, several exemplary embodiments are provided. It should be noted that the descriptions of "first", "second", "third" involved below are 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 indicated technical features. Therefore, the description with "first", "second" and the like can explicitly or implicitly include at least one of the features. That is, "first embodiment", "second embodiment" and "third embodiment" do not refer to only one embodiment respectively, but can refer to multiple embodiments respectively. In addition, the first embodiment, the second embodiment and the third embodiment do not refer to three different example schemes, and the first embodiment, the second embodiment and the third embodiment can have the same or similar parts. For example, the foregoing at this position can be considered as the same or similar parts in the first embodiment, the second embodiment and the third embodiment.

[0045] First embodiment (Fig. 1 to Fig. 9)

[0046] The first embodiment of the present application provides an atomizer 10, which comprises a shell 1 and an atomization component 2, the inside of the shell 1 is provided with an installation cavity 1011, and the atomization component 2 is provided with a plurality of atomization components 2, each of which is installed in the installation cavity 1011. The atomization component 2 stores an aerosol generating substrate and is used to atomize the aerosol generating substrate into an aerosol, and the inside of each atomization component 2 is provided with an airflow passage 21 for the flow of aerosol.

[0047] Referring to FIGS. 1-3, each atomization assembly 2 is internally provided with an airflow passage 21 for the flow of aerosol, and the airflow passages 21 collectively flow multiple types of aerosol. The shell 1 is further provided with a mixing chamber 1012 and multiple sub-air passages 121 spaced apart from each other, each sub-air passage 121 is in one-to-one communication with a corresponding airflow passage 21, and each sub-air passage 121 guides the flow of one type of aerosol. One end (lower end) of the mixing chamber 1012 is connected to each sub-air passage 121 so that the aerosol in each sub-air passage 121 mixes in the mixing chamber 1012; the other end (upper end) of the mixing chamber 1012 forms an outlet 1013, and the mixed aerosol is guided out of the mixing chamber 1012 through the outlet 1013. For example, in the schematic diagram shown in FIG. 3, the first atomization assembly 2a is provided with a first airflow passage 21a, and the second atomization assembly 2b is provided with a second airflow passage 21b, the first airflow passage 21a is for the flow of a first type of aerosol, and the second airflow passage 21b is for the flow of a second type of aerosol; the first sub-air passage 121a is in communication with the first airflow passage 21a to guide the first type of aerosol into the mixing chamber 1012, and the second sub-air passage 121b is in communication with the second airflow passage 21b to guide the second type of aerosol into the mixing chamber 1012; the first type of aerosol and the second type of aerosol are mixed in the mixing chamber 1012 first, and then guided out of the mixing chamber 1012 through the outlet 1013, and finally into the user's oral cavity.

[0048] It should be noted that the mixing chamber 1012 can be directly communicated with the oral cavity through the outlet 1013, or indirectly communicated with the oral cavity through other components, but no matter which embodiment is provided, the mixed aerosol in the mixing chamber 1012 can be guided out of the mixing chamber 1012 through the outlet 1013, but "guided out of the mixing chamber 1012 through the outlet 1013" does not mean "guided out of the atomizer 10 through the outlet 1013". Specifically, referring to FIG. 3, in the embodiment shown in the schematic diagram of the present application, the mixing chamber 1012 directly guides the mixed aerosol out of the atomizer 10 through the outlet 1013, i.e., when the user consumes the aerosol, the mixing chamber 1012 directly guides the mixed aerosol into the oral cavity through the outlet 1013, and the mixed aerosol does not need to be guided into the oral cavity through other components, the loss of the mixed aerosol in the process of flowing to the oral cavity is small, and the guiding efficiency of the mixed aerosol is high. In terms of structure, the upper end of the mixing chamber 1012 does not need to be additionally provided with other components to guide the mixed aerosol into the oral cavity, which simplifies the flow path structure in the shell 1 and facilitates the molding of the shell 1. In addition, in terms of taste, the mixing chamber 1012 directly guides the mixed aerosol into the oral cavity through the outlet 1013, which also reduces the loss of large droplets in the mixed aerosol during the flow process, so that the mixed aerosol guided into the oral cavity has a large proportion of large droplets, which is beneficial to increase the sweetness of the mixed aerosol.

[0049] For the convenience of understanding the mixing effect of the mixing chamber 1012, referring to FIG. 3, a cross section in the first direction N1 is made at one end of the mixing chamber 1012, and according to the foregoing, the one end (lower end) of the mixing chamber 1012 is communicated with each sub-air duct 121, so it can be understood that the cross-sectional area of the mixing chamber 1012 at this position is greater than that of the sub-air duct 121. According to Bernoulli's principle, the greater the cross-sectional area, the lower the pressure, the slower the fluid flow rate, and the greater the fluid flow per unit time, so at the position where the mixing chamber 1012 is connected with the sub-air duct 121 (the lower end of the mixing chamber 1012), the aerosol flow rate is slower, the flow is larger, which can be simply understood as that when multiple aerosols enter the mixing chamber 1012 from the sub-air duct 121, the mixing chamber 1012 is filled, each aerosol exchanges gas molecules and large droplets, and "mixing" is achieved. It should be noted that the first direction N1 is the direction in which the atomizer 10 directs the aerosol, and it is also the height direction of the atomizer 10 in the three-dimensional coordinate system, wherein the first direction N1 is the direction from bottom to top of the atomizer 10 in the use state, and in the schematic diagram shown in the application, the first direction N1 is approximately vertical, so the cross-sectional direction perpendicular to the first direction N1 is horizontal.

[0050] The atomizer 10 provided by the first embodiment comprises a shell 1 and a plurality of atomization assemblies 2, the shell 1 is internally provided with a plurality of installation cavities 1011, and the atomization assemblies 2 are arranged in the installation cavities 1011. The atomization assemblies 2 store aerosol generating substrates and are used for atomizing the aerosol generating substrates into aerosols. Each of the atomization assemblies 2 is internally provided with an airflow channel 21 for the flow of the aerosols. The shell 1 is further provided with a mixing cavity 1012 and a plurality of sub-air channels 121 which are spaced apart from each other. Each of the sub-air channels 121 is in one-to-one communication with a corresponding airflow channel 21. One end of the mixing cavity 1012 is connected with each of the sub-air channels 121, and the other end of the mixing cavity 1012 forms an outlet 1013 for the discharge of the mixed aerosols. The plurality of aerosol generating substrates in each of the atomization assemblies 2 generate a plurality of aerosols. Each of the aerosols sequentially flows through the airflow channel 21, the sub-air channel 121 and the mixing cavity 1012. The mixing cavity 1012 is in communication with each of the sub-air channels 121, so that the plurality of aerosols are mixed in the mixing cavity 1012 and then discharged out of the mixing cavity 1012 through the outlet 1013. The provision of the mixing cavity 1012 increases the mixing path in the aerosol discharge path. The plurality of aerosols are not discharged into the oral cavity one by one for mixing, but are partially or completely mixed in the mixing cavity 1012 before being discharged into the oral cavity, thereby improving the mixing effect of the atomizer 10 on the plurality of aerosols, reducing the taste stratification of the plurality of aerosols in the oral cavity of the user, and improving the user experience. At the same time, when the mixed aerosols are directly discharged into the oral cavity through the outlet 1013 of the mixing cavity 1012, the discharge efficiency of the mixed aerosols is relatively high, and the loss of large droplets in the mixed aerosols is relatively small, which is beneficial to maintaining the large droplet content of the mixed aerosols discharged into the oral cavity, so as to maintain the sweetness of the mixed aerosols. The discharge efficiency of the mixed aerosols is relatively high, and there is no need to additionally arrange other structures and components to discharge the mixed aerosols, which is beneficial to simplifying the flow channel structure of the mixed air channel and the flow channel structure of the shell. In addition, in this embodiment, the loss of large droplets in the mixed aerosols is relatively small, which is beneficial to maintaining the large droplet content of the mixed aerosols discharged into the oral cavity, so as to maintain the sweetness of the mixed aerosols.

[0051] In some embodiments, referring to FIG. 3, the airflow channel 21, the sub-air passage 121 and the mixing cavity 1012 are sequentially connected along the first direction N1. One end (lower end) of the sub-air passage 121 is connected to the airflow channel 21, and the other end (upper end) of the sub-air passage 121 is connected to the mixing cavity 1012, that is, the airflow channel 21 is below the sub-air passage 121, and the mixing cavity 1012 is above the sub-air passage 121 and downstream of the aerosol flow direction. Wherein, the airflow channel 21 and the sub-air passage 121 are coaxially arranged, then it can be understood that the airflow channel 21 and the sub-air passage 121 are rotary bodies with a central axis, and the central axis of the airflow channel 21 and the extension line of the central axis of the sub-air passage 121 are the same straight line. That is, the axis extension direction of the airflow channel 21 and the sub-air passage 121 in the three-dimensional coordinate system is in the first direction N1, which can be simply understood as the airflow channel 21 and the sub-air passage 121 are coaxially connected above and below and extend along the first direction N1, so that the aerosol in the airflow channel 21 is directly introduced into the sub-air passage 121 along the first direction N1, the aerosol flow path between the airflow channel 21 and the sub-air passage 121 is straight, the aerosol flow path is simple, the aerosol guiding efficiency is higher, and the flow loss of the aerosol between the airflow channel 21 and the sub-air passage 121 is smaller, so that the aerosol introduced into the mixing cavity 1012 has a higher large droplet proportion, which is beneficial to maintaining the sweetness of the aerosol. At the same time, due to the relatively simple aerosol flow path between the airflow channel 21 and the sub-air passage 121, the internal flow channel of the atomizer 10 is relatively simple, which is beneficial to simplify the structure of the atomizer 10 and reduce the assembly difficulty of the atomizer 10.

[0052] In some embodiments, referring to FIG. 4, the cross-sectional area of the mixing cavity 1012 is a constant value, wherein the cross-sectional direction is perpendicular to the first direction N1. The cross-sectional area of the mixing cavity 1012 being a constant value means that the cross-sectional area of each place in the mixing cavity 1012 is a fixed value, for example, the cross-sectional area at the outlet 1013 is equal to the flow channel cross-sectional area at any place in the mixing cavity 1012, that is, the inner wall surface surrounding the mixing cavity 1012 is parallel to the first direction N1, and the extension line of the inner wall surface surrounding the mixing cavity 1012 is a straight line parallel to the first direction N1 in the cross section (the cross section shown in the schematic view). The mixing cavity 1012 has a simple inner wall surface, which further simplifies the flow channel structure of the atomizer 10 and reduces the processing and forming difficulty of the shell 1. At the same time, it also makes the aerosols in the mixing cavity 1012 have a simple flow path, reduces the collision effect of the inner wall of the mixing cavity 1012 on the aerosols, so that the mixed aerosol is not blocked and directly guided out through the outlet 1013, which is beneficial to reduce the large droplet loss in the mixed aerosol.

[0053] In some embodiments, referring to FIG. 4, the inner wall surface of each sub-air passage 121 is tangent to the mixing chamber 1012, the sub-air passage 121 is tangent to the mixing chamber 1012, and the tangent point is located in the mixing chamber 1012, that is, the inner wall surface of the sub-air passage 121 is connected to the inner wall surface of the mixing chamber 1012, and the sub-air passage 121 is located in the mixing chamber 1012 (as shown in FIG. 2) in the top view. As described above, the inner wall surface surrounding the mixing chamber 1012 is parallel to the first direction N1, so the inner wall surface surrounding the sub-air passage 121 is also parallel to the first direction N1. In the cross section in the first direction N1, the extension of the inner side wall surrounding the mixing chamber 1012 and the inner side wall surrounding the sub-air passage 121 are both straight lines parallel to the first direction N1. The aerosol is guided into the mixing chamber 1012 from the sub-air passage 121 along the first direction N1, and the aerosol flow path between the sub-air passage 121 and the mixing chamber 1012 is also a straight line. Referring to FIG. 3, taking each group of atomization assemblies 2 as an example, the aerosol is guided into the sub-air passage 121 from the airflow passage 21 along a straight line, and then guided into the mixing chamber 1012 along a straight line. The flow path of the aerosol before mixing is a straight line, so each kind of aerosol in the atomizer 10 has a high guiding-out efficiency and a simple flow path, and the loss of each kind of aerosol before mixing is small, so that the aerosol guided into the mixing chamber 1012 has a high proportion of large droplets, which can further maintain the taste of the aerosol.

[0054] In some embodiments, referring to FIG. 4 and FIG. 5, the mixing cavity 1012 extends along the first direction N1 to the edge of the housing 1, that is, the mixed aerosol in the mixing cavity 1012 is directly guided out of the housing 1 via the outlet 1013, that is, the mixed aerosol can be directly guided into the cavity via the outlet 1013. In FIG. 5, the mixing cavity 1012 extends along the first direction N1, and it can be understood that the extension direction of the mixing cavity 1012 can be understood as the largest dimension of the mixing cavity 1012 in the three-dimensional coordinate system, that is, the profile size of the mixing cavity 1012 in the first direction N1 is the longest. Therefore, in FIG. 5, the size of the mixing cavity 1012 in the second direction N2 is smaller than the size of the mixing cavity 1012 in the first direction N1, wherein the second direction is perpendicular to the first direction N1, and the second direction N2 is the largest dimension of the mixing cavity 1012 in the horizontal direction of the three-dimensional coordinate system, which can be simply understood as the width direction of the mixing cavity 1012, and in the schematic diagram of the present application, N2 represents the second direction. The size of the mixing cavity 1012 in the first direction N1 is larger and prolongs the path of the mixed aerosol flowing to the outlet 1013, which is beneficial for the mixing of multiple aerosols in the mixing cavity 1012. In some possible embodiments, the mixing cavity 1012 can also extend along the second direction N2, that is, the largest profile size of the mixing cavity 1012 is in the second direction N2 (as shown in FIG. 4), which is beneficial for increasing the volume of the mixing cavity 1012 and also allows the mixing cavity 1012 to have sufficient space to mix multiple aerosols, but the first direction N1 is consistent with the flow direction of the mixed aerosol, and the largest profile size of the mixing cavity 1012 is arranged in the first direction N1, which is beneficial for the mixed aerosol to be mixed again during the process of being guided to the outlet 1013, thereby improving the mixing effect of the multiple aerosols to make the user obtain a better taste.

[0055] In some possible embodiments, referring to FIG. 3-FIG. 5, the housing 1 can be combined by at least two components, the mixing cavity 1012 is in the first component, each sub-air channel 121 and the airflow passage 21 are in the second component, the first component is sleeved outside the second component, and the first component can be lifted relative to the second component to control the distance between the top end (outlet 1013) of the first component and the sub-air channel 121 in the second component, that is, by controlling the distance of the first component relative to the second component, the size of the mixing cavity 1012 in the first direction N1 can be controlled, thereby controlling the length of the mixing path of the mixed aerosol, so that the mixing effect and the guiding-out time of the mixed aerosol are controllable, which is convenient for meeting the individual needs of users.

[0056] In some embodiments, referring to FIGS. 3 and 4, the cross-sectional areas of at least two of the sub-air channels 121 are different, where the cross-sectional direction is perpendicular to the first direction N1. When the number of sub-air channels 121 is greater than two, for example, the housing 1 is provided with three sub-air channels 121, it can be understood that the cross-sectional areas of the three sub-air channels 121 can all be different, or the cross-sectional areas of two of the three sub-air channels 121 can be different. In the embodiment shown in the schematic diagram of the present application, the housing 1 is provided with two sub-air channels 121, and the cross-sectional areas of the first sub-air channel 121a and the second sub-air channel 121b are different. According to Bernoulli's principle, the flow rate and flow volume of fluid are related to the cross-sectional area of the flow channel, and the aerosol generating substrates in each atomization assembly 2 are different, so the amount of aerosol or the time of aerosol in each atomization assembly 2 is also different. For example, the amount of the first aerosol in the first atomization assembly 2a is larger, and the amount of the second aerosol in the second atomization assembly 2b is smaller. Therefore, the cross-sectional area of the first sub-air channel 121a is smaller than that of the second sub-air channel 121b, so as to balance the flow rate and flow volume of the first aerosol and the second aerosol, control the time when the first aerosol and the second aerosol reach the mixing chamber 1012, and control the flow volume of the first aerosol and the second aerosol introduced into the mixing chamber 1012 per unit time, so that the two kinds of aerosols can be introduced into the mixing chamber 1012 at the same time and uniformly, which is easy to mix various aerosols uniformly, that is, the content of each kind of aerosol in the mixed aerosol is approximately equal, thereby further improving the mixing effect of the atomizer 10 and reducing the layered taste.

[0057] In some possible embodiments, referring to FIG. 3, the lengths of at least two of the sub-air channels 121 in the first direction N1 are different, so as to control the time when the aerosol is introduced into the mixing chamber 1012 by controlling the length of the flow path of the aerosol in the sub-air channel 121, which can be designed according to the structural space in the housing 1. Specifically, when the housing 1 is provided with two sub-air channels 121, the cross-sectional areas of the two sub-air channels 121 can be different, or the lengths of the two sub-air channels 121 can be different, or the cross-sectional areas and lengths of the two sub-air channels 121 can all be different. Regardless of whether the length of the flow path of the aerosol in the sub-air channel 121 is controlled or the flow rate of the aerosol in the sub-air channel 121 is controlled, the time when the multiple aerosols reach the mixing chamber 1012 can be controlled, so that the multiple aerosols can be introduced into the mixing chamber 1012 at the same time, which is easy to mix various aerosols uniformly in the mixing chamber 1012.

[0058] In some embodiments, referring to FIG. 3, the cross-sectional area of the airflow channel 21 is equal to the cross-sectional area of the connected sub-air passage 121, where the cross-sectional direction is perpendicular to the first direction N1. It can be understood that the cross-sectional area of the airflow channel 21 and the cross-sectional area of the sub-air passage 121 are constant values, which further simplifies the flow channel structure in the atomizer 10. In FIG. 3, the cross-sectional area of the first airflow channel 21a is equal to the cross-sectional area of the first sub-air passage 121a, the cross-sectional area of the second airflow channel 21b is equal to the cross-sectional area of the second sub-air passage 121b, and the first airflow channel 21a is coaxially arranged with the first sub-air passage 121a, and the second airflow channel 21b is coaxially arranged with the second sub-air passage 121b. Taking the first airflow channel 21a and the first sub-air passage 121a as an example, the first kind of aerosol is less likely to be collided and blocked by the inner wall surface of the first sub-air passage 121a during the process of being introduced from the first airflow channel 21a into the first sub-air passage 121a, and the flow speed of the first kind of aerosol in the first airflow channel 21a and the first sub-air passage 121a is approximately equal, which is beneficial to uniformly introducing the first kind of aerosol into the mixing chamber 1012, so as to reduce the possibility of the first kind of aerosol forming turbulence due to collision or pressure change, and further reduce the large droplet loss of the first kind of aerosol before being introduced into the mixing chamber 1012.

[0059] In some embodiments, referring to FIG. 3, the cross-sectional area of the airflow channel 21 is greater than the cross-sectional area of the connected sub-air passage 121. It can be that the cross-sectional area of the airflow channel 21 and the cross-sectional area of the sub-air passage 121 are constant values; it can also be that the cross-sectional area of the airflow channel 21 and the cross-sectional area of one or both of the sub-air passages 121 are not constant values, that is, the cross-sectional area of the airflow channel 21 can increase or decrease along the first direction N1, and / or the cross-sectional area of the sub-air passage 121 can increase or decrease along the first direction N1. However, whether the cross-sectional area of the airflow channel 21 and the cross-sectional area of the sub-air passage 121 are constant values, as long as the minimum flow channel cross-sectional area of the airflow channel 21 is greater than the maximum flow channel cross-sectional area of the connected sub-air passage 121, it can be considered that the cross-sectional area of the airflow channel 21 is greater than the cross-sectional area of the connected sub-air passage 121.

[0060] Specifically, referring to FIG. 3, the cross-sectional area of the first airflow passage 21a is greater than that of the first sub-air passage 121a, the cross-sectional area of the second airflow passage 21b is greater than that of the second sub-air passage 121b, and the first airflow passage 21a is coaxially arranged with the first sub-air passage 121a, and the second airflow passage 21b is coaxially arranged with the second sub-air passage 121b. Taking the first airflow passage 21a and the first sub-air passage 121a as an example, according to Bernoulli's principle, the flow velocity of the first aerosol in the first airflow passage 21a is less than that in the first sub-air passage 121a, and in the process of introducing the first aerosol from the first airflow passage 21a into the first sub-air passage 121a, the first aerosol accelerates to generate inertial acceleration, which can increase the speed of the first aerosol introduced into the mixing chamber 1012, facilitating rapid mixing of each aerosol to enable the user to quickly obtain the mixed aerosol. In some possible embodiments, the cross-sectional area of the airflow passage 21 and / or the sub-air passage 121 can also decrease along the first direction N1 to further increase the flow rate of each aerosol by using Bernoulli's principle.

[0061] In some embodiments, referring to FIGS. 3 and 4, the shell 1 includes the mounting portion 11 and the air passage portion 12 connected along the first direction N1, that is, the mounting portion 11 is located below the air passage portion 12. The air passage portion 12 forms the mixing chamber 1012 and each sub-air passage 121, and the mounting portion 11 forms the mounting chamber 1011. The air passage portion 12 and the mounting portion 11 belong to two different parts of the shell 1, that is, the shell 1 is integrally formed with the sub-air passages 121 and the mixing chamber 1012, and there is no assembly gap between the sub-air passages 121 and the mixing chamber 1012. The sealing structure for filling the assembly gap between the sub-air passages 121 and the mixing chamber 1012 is omitted, the structure of the atomizer 10 is relatively simple, and the assembly operation of the atomizer 10 is simplified.

[0062] Specifically, referring to FIGS. 3, 4 and 6, the shell 1 includes a housing 101 and a base 102, the mounting portion 11 and the air passage portion 12 are formed on the housing 101, and the top surface of the base 102 and the inner wall surface of the mounting portion 11 jointly enclose the mounting chamber 1011 after the base 102 is buckled with the housing 101. The detachably connected housing 101 and the base 102 jointly form the shell 1, which simplifies the difficulty of installing the atomization assembly 2 inside the shell 1. The base 102 is provided with an air inlet 1021 to introduce external atmosphere into the mounting chamber 1011. The external atmosphere flows into the atomization assembly 2 as shown by the dashed arrows in FIG. 3, and then drives the aerosol to flow upward as shown by the solid arrows in FIG. 3.

[0063] In some embodiments, referring to FIGS. 3, 6 and 7, the atomization assembly 2 comprises an inner shell 22 and an atomization tube 23, the inner shell 22 is internally provided with a sub-cavity 221, the atomization tube 23 is arranged in the sub-cavity 221, the atomization tube 23 internally forms an airflow channel 21 and an atomization cavity 230, aerosol is formed in the atomization cavity 230, that is, the aerosol generating substrate is converted into aerosol at the atomization cavity 230, the atomization tube 23 integrally forms the airflow channel 21 and the atomization cavity 230, so that the atomization cavity 230 is formed on the gas flow path of the external atmosphere, the gas flow path passes through the position where the atomization cavity 230 is located, the external atmosphere carries the aerosol in the atomization cavity 230 along a straight line during the flow process, and the aerosol is guided to the sub-air passage 121 through the airflow channel 21. The sub-cavity 221 is used to store the aerosol generating substrate or accommodate components for storing the aerosol generating substrate, but no matter how it is arranged, the aerosol generating substrate is stored in the sub-cavity 221, and a plurality of sub-cavities 221 collectively store a plurality of aerosol generating substrates. Specifically, the sub-cavity 221 can directly store liquid aerosol generating substrate, or can lock the aerosol generating substrate with a water-absorbing material, for example, referring to FIG. 7, the aerosol generating substrate can be adsorbed by the oil storage cotton 24, and the sub-cavity 221 stores the aerosol generating substrate through the oil storage cotton 24.

[0064] Referring to FIGS. 3, 6 and 7, each atomization assembly 2 can share some parts and be connected into one module, and each atomization assembly 2 can also be a plurality of independent modules with the same structure, as long as each atomization assembly 2 can store a plurality of aerosol generating substrates and generate a plurality of aerosols. Specifically, the inner shell 22 comprises an upper cover 223, an inner sleeve 224 and a lower cover 225, the lower cover 225, the inner sleeve 224 and the upper cover 223 are connected in sequence along the first direction N1, wherein the inner wall surface of the inner sleeve 224, the lower wall surface of the upper cover 223 and the upper wall surface of the upper cover 223 collectively enclose a sub-cavity 221, the inner sleeve 224 is clamped between the upper cover 223 and the lower cover 225, the height between the upper cover 223 and the lower cover 225 is adjusted, and / or the thickness of the upper cover 223 and the lower cover 225 embedded into the sub-cavity 221 is adjusted, so as to adjust the volume of the sub-cavity 221. In some possible embodiments, referring to FIG. 7, at least the lower cover 225 is provided with a liquid collecting groove 2251 on the side opposite to the upper cover 223. It can be understood that the upper cover 223 and the lower cover 225 can both be provided with the liquid collecting groove 2251, or only the lower cover 225 can be provided with the liquid collecting groove 2251. The provision of the liquid collecting groove 2251 increases the roughness of the inner end surface of the lower cover 225 (and the upper cover 223), which facilitates stable installation of the oil storage cotton 24 in the sub-cavity 221. At the same time, the liquid collecting groove 2251 can also collect part of the aerosol generating substrate, reducing the possibility of overflow of the aerosol generating substrate separated from the oil storage cotton 24 due to sharp temperature change.

[0065] Referring to FIG. 7, in each atomization assembly 2, the upper covers 223 of at least two atomization assemblies 2 are connected as one component, and / or the lower covers 225 of at least two atomization assemblies 2 are connected as one component. In the embodiment shown in the schematic view of the present application, the upper covers 223 in each atomization assembly 2 are connected as an upper seat, the lower covers 225 in each atomization assembly 2 are connected as a lower seat, and the plurality of inner housings 22 are arranged between the upper seat and the lower seat, i.e., each atomization assembly 2 is assembled as a module. It should be noted that the upper covers 223 and / or the lower covers 225 can be integrally formed or assembled by a plurality of upper covers 223 and / or a plurality of lower covers 225 through a connecting structure, but regardless of the foregoing embodiment, each upper cover 223 is assembled as a whole, and each lower cover 225 is assembled as another whole, so that each atomization assembly 2 is connected as a module. For ease of explanation, the module assembled by each atomization assembly 2 is defined as an “atomization module”, so that during assembly and disassembly, each atomization assembly 2 does not need to be disassembled one by one, but the atomization module is disassembled or assembled at one time, so that each atomization assembly 2 can be installed in the installation cavity 1011 or disassembled out of the installation cavity 1011, which is convenient to implement and simplifies the assembly and disassembly operation of each atomization assembly 2 and the outer shell 1.

[0066] In some embodiments, referring to FIGS. 3, 7 and 8, the atomization pipe 23 includes a first sub-pipe 231, a second sub-pipe 232 and a liquid guide 233, the first sub-pipe 231 is connected to the second sub-pipe 232, and the first sub-pipe 231 and the second sub-pipe 232 jointly enclose the airflow channel 21. The airflow channel 21 is jointly formed by the first sub-pipe 231 and the second sub-pipe 232, which reduces the processing and forming difficulty of the airflow channel 21. The second sub-pipe 232 is connected to the mixing cavity 1012, and the first sub-pipe 231 is connected to the lower cover 225 of the inner housing 22, i.e., the second sub-pipe 232 is located above the first sub-pipe 231. The first sub-pipe 231 and the second sub-pipe 232 can be coaxially arranged and partially nested, i.e., the second sub-pipe 232 is partially inserted into the first sub-pipe 231; the first sub-pipe 231 and the second sub-pipe 232 can also be up and down clamped through a clamping structure. Regardless of how the first sub-pipe 231 and the second sub-pipe 232 are arranged, as long as the first sub-pipe 231 and the second sub-pipe 232 jointly enclose the airflow channel 21.

[0067] Referring to FIG. 3, FIG. 7 and FIG. 8, the atomization assembly 2 further comprises a heating body 25 for atomizing the aerosol generating substrate into aerosol, at least one heating body 25 is arranged in each atomization tube 23, that is, a plurality of heating bodies 25 can be arranged in one atomization assembly 2. Specifically, referring to FIG. 3 and FIG. 7, the heating body 25 comprises a heating piece 251, an electrical connecting piece 252 and a wire 253, the heating piece 251 is installed in the liquid guide piece 233, the electrical connecting piece 252 is installed on the base 102 of the outer shell 1, and the wire 253 connects the heating piece 251 and the electrical connecting piece 252. One heating piece 251 can be provided with a plurality of electrical connecting pieces 252 to respectively start and stop each group of atomization assemblies 2, and / or control the atomization power of each group of atomization assemblies 2; one electrical connecting piece 252 can also simultaneously connect a plurality of heating pieces 251 to reduce the circuit layout difficulty of the electrical connecting piece 252, and also control the plurality of heating pieces 251 to start and stop at the same time, so that each atomization assembly atomizes at the same time and closes at the same time.

[0068] Specifically, in the schematic diagram shown in the present application, one heating piece 251 is connected with two wires 253, and each wire 253 is connected with one electrical connecting piece 252, that is, two electrical connecting pieces 252 simultaneously control one heating piece 251 to work.

[0069] It should be noted that the materials of the first sub-tube 231 and the second sub-tube 232 can be the same or different. For example, the first sub-tube 231 can be made of rigid material to stably install the first sub-tube 231 on the inner shell 22 by using the structural strength of the rigid material, and also to accelerate the conversion of the aerosol generating substrate into aerosol by using the electrical conductivity and thermal conductivity of the rigid material. The second sub-tube 232 can be a plastic tube, a glass fiber tube, a steel tube, etc. In some possible embodiments, the first sub-tube 231 is a steel tube, and the second sub-tube 232 is a glass fiber tube. The steel tube has high structural strength, the glass fiber tube is light and hard, the first sub-tube 231 and the second sub-tube 232 both have high mechanical strength, are anti-aging, resistant to high temperature and corrosion, so that the atomization tube 23 can be used in various working conditions and has a long service life.

[0070] Referring to FIGS. 3, 7 and 8, the liquid guide 233 is disposed inside the first sub-tube 231 and / or the second sub-tube 232, and the liquid guide 233 is connected with the heating body 25. The liquid guide 233 encloses the atomization cavity 230, and guides the aerosol generating substrate to the atomization cavity 230, so that the heating body 25 atomizes the aerosol generating substrate into aerosol. The liquid guide 233 can be disposed inside the first sub-tube 231, the liquid guide 233 can be disposed inside the second sub-tube 232, or the liquid guide 233 can be disposed inside the first sub-tube 231 and the second sub-tube 232 at the position where the first sub-tube 231 and the second sub-tube 232 are connected. Regardless of the specific position of the liquid guide 233, the liquid guide 233 is located in the airflow passage 21, so that the atomization cavity 230 is formed on the gas flow path in the airflow passage 21; and the liquid guide 233 can guide the aerosol generating substrate in the sub-cavity 221 to the heating body 25. The liquid guide 233 is made of porous ceramic or cotton material, and the porous ceramic material includes but is not limited to alumina, silica, silicon nitride, silicate or silicon carbide. The aerosol generating substrate enters the atomization cavity 230 through the liquid guide 233 under the capillary action.

[0071] In some embodiments, referring to FIGS. 3 and 6, the atomizer 10 further includes a liquid suction member 3 disposed between the housing 1 and the atomization assembly 2, the liquid suction member 3 is used to absorb the condensed liquid, the liquid suction member 3 is formed with a connection passage 31 communicating the airflow passage 21 and the sub-air channel 121, and the liquid suction member 3 is located above the atomization assembly 2. The cross-sectional area of the connection passage 31 is larger than that of the airflow passage 21 and the sub-air channel 121. For example, the first connection passage 31a communicates the first airflow passage 21a and the first sub-air channel 121a, and the cross-sectional area of the first connection passage 31a is larger than that of the first airflow passage 21a and the first sub-air channel 121a; the second connection passage 31b communicates the second airflow passage 21b and the second sub-air channel 121b, and the cross-sectional area of the second connection passage 31b is larger than that of the second airflow passage 21b and the second sub-air channel 121b. The larger cross-sectional area of the flow passage of the connection passage 31 reduces the collision of the aerosol with the inner wall of the connection passage 31, and also reduces the possibility of the liquid suction member 3 sucking large droplets in the aerosol. The connection passage 31 is coaxially arranged with the airflow passage 21, and then the connection passage 31 is coaxially arranged with the sub-air channel 121. The connection passage 31 is located between the sub-air channel 121 and the airflow passage 21, so as to be able to absorb the condensed liquid at the sub-air channel 121 and the airflow passage 21 after the temperature in the atomizer 10 is reduced, and reduce the possibility of the condensed liquid leaking into the assembly gap in the atomizer 10 or leaking out of the atomizer 10 through the outlet 1013.

[0072] In some embodiments, referring to FIG. 3 and FIG. 6, the upper cover 223 of the inner shell 22 forms a plurality of limiting grooves 222, each of which has a liquid absorbing piece 3, and each of the liquid absorbing pieces 3 forms a connecting channel 31. Of course, the upper cover 223 of the inner shell 22 can also form a limiting groove 222, which has a liquid absorbing piece 3, and the liquid absorbing piece 3 forms a plurality of connecting channels 31. However, as long as the liquid absorbing piece 3 can connect one airflow channel 21 and one sub-air passage 121 to form one connecting channel 31, and can absorb the condensed liquid at the sub-air passage 121 and the airflow channel 21, the liquid absorbing piece 3 can be arranged in any way. The limiting groove 222 limits the position of the liquid absorbing piece 3, and the liquid absorbing piece 3 is detachably connected to the inner shell 22, which is convenient for disassembling the liquid absorbing piece 3.

[0073] In some embodiments, referring to FIG. 3 and FIG. 6, the cross-sectional areas of at least two connecting channels 31 are different. The condensation points of various aerosols condensing into condensed liquid are different, and the connecting channels 31 are arranged accordingly, so that the condensed liquid condensed by various aerosols can be absorbed. Of course, by adjusting the cross-sectional area of the connecting channel 31, the flow rate and flow volume of various aerosols introduced from the airflow channel 21 to the sub-air passage 121 can be controlled. Compared with the embodiment of adjusting the cross-sectional area of the airflow channel 21 and / or the sub-air passage 121 to control the flow rate and flow volume of the aerosol, the structure of the liquid absorbing piece 3 is simple, so the cross-sectional area of the connecting channel 31 is easier to adjust, and it is convenient to adjust the cross-sectional area of the connecting channel 31 to control the flow rate and flow volume of each kind of aerosol, so that each kind of aerosol can enter the mixing chamber 1012 at the same time, and the proportion of each kind of aerosol in the mixed aerosol is approximately the same.

[0074] In the embodiment shown in the schematic diagram of the present application, the atomizer 10 is provided with two connecting channels 31, the first connecting channel 31a and the second connecting channel 31b have different cross-sectional areas. Different types of aerosol condense into condensed liquid at different dew points, and the connecting channels 31 are set accordingly, so that the condensed liquid condensed by various aerosols can be absorbed. Of course, by adjusting the cross-sectional area of the connecting channel 31, the flow rate and flow of various aerosols introduced into the mixing chamber 1012 from the airflow channel 21 can be controlled. According to Bernoulli's principle, the flow rate and flow of the fluid are related to the cross-sectional area of the flow channel. The aerosol generating substrates in each atomization assembly 2 are different, so the amount of mist or mist time of the aerosol in each atomization assembly 2 is also different. For example, the amount of mist of the first aerosol in the first atomization assembly 2a is larger, and the amount of mist of the second aerosol in the second atomization assembly 2b is smaller. Then, the cross-sectional area of the first connecting channel 31a is smaller than that of the second connecting channel 31b, so that the flow rate and flow of the first aerosol and the second aerosol can be balanced, thereby controlling the time when the first aerosol and the second aerosol reach the mixing chamber 1012, and the flow of the first aerosol and the second aerosol introduced into the mixing chamber 1012 per unit time. It is feasible to introduce two types of aerosols into the mixing chamber 1012 at the same time and uniformly, so that various aerosols can be mixed more uniformly, that is, the content of each type of aerosol in the mixed aerosol is approximately equal, which further improves the mixing effect of the atomizer 10 and reduces the layered taste.

[0075] In some embodiments, referring to FIGS. 3 and 6, the atomizer 10 further includes a liquid storage member 4, which is arranged between the base 102 of the shell 1 and the atomization assembly 2, i.e., the liquid storage member 4 is located below the atomization assembly 2. The liquid storage member 4 is used to absorb the condensed liquid, and the liquid storage member 4 has a through hole 41 in which the heating element 25 is sleeved. A plurality of liquid storage members 4 can be arranged below the atomization assembly 2, and each liquid storage member 4 has one through hole 41. Alternatively, one liquid storage member 4 can be arranged below the atomization assembly 2, and the liquid storage member 4 has a plurality of through holes 41. Regardless of the structure of the liquid storage member 4, as long as the exterior of each heating element 25 is surrounded by the through hole 41. Of course, in some possible embodiments, a plurality of heating elements 25 can be sleeved in one through hole 41.

[0076] Specifically, referring to FIGS. 3 and 6, a liquid storage member 4 is arranged below the atomization assembly 2, and the liquid storage member 4 is mounted on the base 102 of the shell 1. The liquid storage member 4 is provided with a plurality of through holes 41, each through hole 41 sleeving a heating element 25, and further, each through hole 41 can sleeve one or more electrical connectors 252 in a group of heating elements 25. After the atomizer 10 is turned off, the heating element 25 generates condensed liquid due to temperature reduction, and the liquid storage member 4 absorbs the condensed liquid generated by the heating element 25 (the electrical connector 252) to reduce the risk of short circuit of the heating element 25 affected by the condensed liquid.

[0077] As shown in FIG. 9, the first embodiment of the present application further provides an electronic atomization device, which can be an electronic cigarette, an electronic medical atomizer or an electronic beauty atomizer, etc., and the electronic atomization device comprises the above-mentioned atomizer 10. The electronic atomization device further comprises a power supply 20, which is electrically connected with the atomization assembly 2 in the atomizer 10, and the power supply 20 supplies power to the atomizer 10 to drive the atomization assembly 2 to work. Specifically, the power supply 20 is arranged outside the mounting cavity 1011 (refer to FIG. 4), and the power supply 20 is electrically connected with the electrical connector 252 (refer to FIG. 7) to provide electrical energy for the heating element 251 and to be able to control the start and stop of the heating element 251 and control the heating power of the heating element 251. The specific type of the power supply 20 is not limited in the present application, for example, the power supply 20 can be a lithium battery. The present application protects an electronic atomization device configured with the above-mentioned atomizer 10, so that the electronic atomization device in the present application has better mixing effect and can improve the user's actual use experience. The atomizer 10 included in the electronic atomization device of the first embodiment is the atomizer 10 provided in the first embodiment.

[0078] Second embodiment (FIGS. 6-14)

[0079] The second embodiment provides an atomizer 10, which comprises a housing 1 and atomization assemblies 2, the housing 1 is internally provided with a mounting cavity 1011 and an airflow passage 21 connected in sequence along a first direction N1, and the atomization assemblies 2 are provided in plurality, each of the atomization assemblies 2 is installed in the mounting cavity 1011, and the atomization assemblies 2 store aerosol generating substrates and are used for atomizing the aerosol generating substrates into aerosols.

[0080] Referring to FIG. 12, each of the atomization assemblies 2 is internally provided with an airflow passage 21 for the flow of aerosol, and the airflow passages 21 collectively flow a plurality of aerosols. One end (lower end) of the mixing chamber 1012 is in communication with the airflow passages 21 to mix the aerosols discharged by the airflow passages 21, and the other end (upper end) of the mixing chamber 1012 forms an outlet 1013 for the mixed aerosol to be discharged. Specifically, referring to FIG. 12, in the embodiment shown in the schematic diagram of the present application, the mixed aerosol in the mixing chamber 1012 is introduced into other components (the contraction chamber 13) via the outlet 1013, and then discharged from the atomizer 10 via the other components and into the oral cavity. In the schematic diagram shown in FIG. 12, the first atomization assembly 2a is provided with a first airflow passage 21a, and the second atomization assembly 2b is provided with a second airflow passage 21b. The first airflow passage 21a is for the flow of a first aerosol, and the second airflow passage 21b is for the flow of a second aerosol. The mixing chamber 1012 is in communication with the first airflow passage 21a and the second airflow passage 21b, and the first aerosol and the second aerosol are mixed in the mixing chamber 1012 before being discharged from the mixing chamber 1012 via the outlet 1013 and finally into the oral cavity of the user. It should be noted that the mixing chamber 1012 can be directly in communication with the oral cavity via the outlet 1013, or indirectly in communication with the oral cavity via other components. Regardless of the implementation, the mixed aerosol in the mixing chamber 1012 can be discharged from the mixing chamber 1012 via the outlet 1013, but "discharged from the mixing chamber 1012 via the outlet 1013" does not mean "discharged from the atomizer 10 via the outlet 1013".

[0081] Referring to FIG. 13, along the first direction N1, the cross-sectional area of the mixing cavity 1012 perpendicular to the first direction N1 is reduced at least partially. As known from the foregoing, the first direction N1 is the height direction of the atomizer 10 in the three-dimensional coordinate system, that is, the first direction N1 is approximately the vertical direction shown in the schematic diagram of the present application. It can be understood that the cross-sectional direction perpendicular to the first direction N1 is approximately the horizontal direction shown in the schematic diagram of the present application. Therefore, the cross-sectional area of the mixing cavity 1012 perpendicular to the first direction N1 is reduced at least partially, that is, the inner wall surrounding the mixing cavity 1012 is at least partially approximately conical from bottom to top. The cross-sectional area of the flow channel of the mixing cavity 1012 can decrease along the first direction N1 (as shown in FIG. 13), or the cross-sectional area of the flow channel of the mixing cavity 1012 can decrease along the first direction N1 (as shown in FIG. 14). At this time, the flow channel of the mixing cavity 1012 decreases from bottom to top, and the cross-sectional area at the outlet 1013 is the minimum cross-sectional area of the mixing cavity 1012. However, no matter which embodiment is used, the aerosol will at least be blocked by the partial inner wall of the mixing cavity 1012 during the flow process. Each aerosol collides with the at least partial inner wall of the mixing cavity 1012 to form a collision turbulent flow. The inner wall with a smaller cross-sectional area of the mixing cavity 1012 blocks the flow of the aerosol and changes the flow direction of the aerosol, so that the plurality of aerosols converge towards the central axis of the mixing cavity 1012. Each aerosol exchanges gas molecules and large droplets, and the mixing is achieved. According to Bernoulli's principle, the smaller the cross-sectional area, the greater the pressure and the faster the fluid flow. The mixed aerosol is at least affected by the partial inner wall of the mixing cavity 1012 to accelerate the flow, the fluid molecular motion speed increases, the mixing rate of each aerosol increases, and the mixing of each aerosol is facilitated.

[0082] In some possible embodiments, the blocking ribs and / or movable wind baffles can be arranged on the part (the first connecting portion 13 and the second connecting portion 14) of the shell 1 surrounding the mixing cavity 1012, and the blocking ribs and the wind baffles are arranged downstream of the flow direction of the aerosol to collide with each aerosol in the first direction N1. The blocking ribs and the wind baffles collide with each aerosol to make each aerosol form a collision turbulent flow more quickly in the mixing cavity 1012, and then make each aerosol mix more fully in the mixing cavity 1012. The wind baffles are movably arranged, so that the flow direction of each aerosol can be adjusted, and / or the flow speed of each aerosol can be changed to improve the mixing effect of each aerosol and meet the individual needs of the user.

[0083] The nebulizer 10 provided by the second embodiment of the present application comprises a shell 1 and a plurality of atomization assemblies 2. The shell 1 is internally provided with a mounting cavity 1011 and an airflow channel 21 connected in sequence along a first direction N1. The atomization assemblies 2 are arranged in the mounting cavity 1011. The atomization assemblies 2 store aerosol generating substrates and are used for atomizing the aerosol generating substrates into aerosols. Each atomization assembly 2 is internally provided with an airflow channel 21 for the flow of the aerosols. One end of a mixing cavity 1012 is in communication with each airflow channel 21 for mixing the aerosols discharged from the airflow channels 21. The other end of the mixing cavity 1012 forms an outlet 1013 for the mixed aerosols to be discharged. The mixed aerosols are discharged from the outlet 1013 to other components (a contraction cavity 13) or outside the nebulizer 10. Along the first direction N1, the cross-sectional area of the mixing cavity 1012 perpendicular to the first direction N1 decreases. The portion of the mixing cavity 1012 with the decreasing cross-sectional area can block the flow of the aerosols and change the flow direction of the aerosols. Each aerosol collides on the inner wall of the mixing cavity 1012 with the decreasing cross-sectional area, forming a collision turbulent flow gradually converging to the central axis of the mixing cavity 1012, achieving “mixing”. The pressure at the portion of the inner wall is relatively high, which can increase the flow speed of the aerosols, and the motion speed of the gas molecules and large droplets in the aerosols is increased, which is beneficial to the rapid and relatively sufficient mixing of the aerosols in the mixing cavity 1012, improving the mixing effect of the nebulizer 10 on the multiple aerosols and reducing the layered taste of the mixed aerosols in the oral cavity, which is beneficial to improving the user experience.

[0084] In some embodiments, referring to FIGS. 12 and 13, the shell 1 is further internally provided with a contraction cavity 13. Along the first direction N1, one end (lower end) of the mixing cavity 1012 is in communication with the mounting cavity 1011, and the other end (upper end) of the mixing cavity 1012 is in communication with the contraction cavity 13, that is, the contraction cavity 13 is above the mixing cavity 1012 and downstream of the flow direction of the aerosols. The mixed aerosols are introduced into the contraction cavity 13 via the outlet 1013 instead of being directly introduced into the oral cavity via the outlet 1013, so as to prolong the flow path of the aerosols in the nebulizer 10, so that the aerosols are more fully mixed in the nebulizer 10. The cross-sectional area of the contraction cavity 13 is smaller than that of the mixing cavity 1012. During the process of being introduced from the mixing cavity 1012 into the contraction cavity 13, the flow speed of the mixed aerosols is increased, and the contraction cavity 13 collides with the mixed aerosols downstream of the mixed aerosols, so that the mixed aerosols are further mixed during the process of being introduced into the contraction cavity 13.

[0085] It should be noted that the cross-sectional area of the contraction cavity 13 can be constant or not constant. Specifically, in the embodiment shown in the schematic diagram of the present application, referring to FIGS. 12 and 13, the cross-sectional area of the contraction cavity 13 is constant, the cross-sectional area of the mixing cavity 1012 at any position is greater than the cross-sectional area of the contraction cavity 13, and the extension direction of the inner wall of the contraction cavity 13 can be parallel to the first direction N1 and vertically extend, so that the flow path of the mixed aerosol in the contraction cavity 13 is straight, the mixed aerosol flows in a straight line in the contraction cavity 13, and the flow loss is small; and the flow path structure of the contraction cavity 13 is relatively simple, which is convenient for simplifying the flow path structure in the atomizer 10 and facilitating the processing and molding of the atomizer 10. Of course, in some possible embodiments, the inner wall of the contraction cavity 13 can also be contracted or expanded along the first direction N1 to be irregular, so as to accelerate or slow down the flow of the mixed aerosol. In this embodiment, the maximum flow path cross-sectional area of the contraction cavity 13 is smaller than the minimum flow path cross-sectional area of the mixing cavity 1012. When the inner wall of the contraction cavity 13 is contracted, the mixed aerosol is concentrated near the central axis of the contraction cavity 13, so as to reduce the taste stratification of the mixed aerosol; when the inner wall of the contraction cavity 13 is expanded, the mixed aerosol is diffused and discharged, so as to increase the flow rate of the aerosol obtained by the user in a unit area.

[0086] In some embodiments, referring to FIGS. 12 and 13, the shell 1 further comprises a discharge cavity 14, one end of the discharge cavity 14 is connected to the contraction cavity 13 along the first direction N1, and the other end forms a discharge outlet 141. The mixed aerosol is discharged to the outside of the atomizer 10 through the discharge outlet 141 and enters the user's oral cavity. The flow path of the aerosol in the atomizer 10 is: the airflow passage 21, the mixing cavity 1012, the contraction cavity 13, and the discharge cavity 14. The cross-sectional area of the discharge cavity 14 is greater than that of the contraction cavity 13. It can be understood that the cross-sectional area of the discharge cavity 14 and / or the contraction cavity 13 can be constant or not constant, as long as the minimum flow path cross-sectional area of the discharge cavity 14 is greater than the maximum flow path cross-sectional area of the contraction cavity 13, the cross-sectional area of the discharge cavity 14 is considered to be greater than that of the contraction cavity 13. The discharge cavity 14 is located downstream of the aerosol flow direction, and forms a discharge outlet 141 capable of discharging the mixed aerosol to the outside of the atomizer 10. The flow path cross-sectional area of the discharge cavity 14 is large, and the flow rate of the mixed aerosol in the discharge cavity 14 is smaller than that in the contraction cavity 13, so that the user obtains mixed aerosol with a comfortable flow rate, reduces the impact on the oral cavity caused by the too fast flow rate of the mixed aerosol, and improves the comfort of the user when eating the mixed aerosol.

[0087] Of course, in some possible embodiments, the cross-sectional areas of the delivery cavity 14 and the contraction cavity 13 can also be equal and constant. That is, the cross-sectional area of the flow passage at any position in the delivery cavity 14 and the contraction cavity 13 is a fixed value, the inner walls of the delivery cavity 14 and the contraction cavity 13 extend along the first direction N1, and the mixed aerosol flows in a straight line in the delivery cavity 14, the contraction cavity 13, and from the delivery cavity 14 into the contraction cavity 13 until entering the user's oral cavity, the inner walls of the delivery cavity 14 and the contraction cavity 13 do not block the aerosol, and the mixed aerosol does not change the flow direction due to the influence of the inner walls of the delivery cavity 14 and the contraction cavity 13, thereby reducing the loss of the mixed aerosol in flowing into the oral cavity, which is beneficial to maintaining the large droplet content of the mixed aerosol. It should be noted that if the aerosol contains a sweet additive, the boiling point, type, and taste of the aerosol generating substrate will affect the proportion of large droplets (large droplet content / ingredient aerosol content) in the generated aerosol, thereby affecting the taste of the aerosol. In the case of a large proportion of large droplets, the aerosol tastes sweet; in the case of a small proportion of large droplets, the aerosol tastes sweet, therefore, reducing the large droplet content in the mixed aerosol is beneficial to maintaining the sweetness of the mixed aerosol.

[0088] In some embodiments, referring to FIGS. 12-14, the portion of the housing 1 that encloses the mixing cavity 1012 includes a first connecting portion 13 and a second connecting portion 14 connected together, the inner cavity of the second connecting portion 14 is connected to the contraction cavity 13, and at least part of the atomization assembly 2 is located in the inner cavity of the first connecting portion 13, that is, the first connecting portion 13 is connected below the second connecting portion 14. The cross-sectional area of the inner cavity of the second connecting portion 14 is smaller than the cross-sectional area of the inner cavity of the first connecting portion 13, and the cross-sectional area of the inner cavity of the second connecting portion 14 decreases along the first direction N1, that is, the cross-sectional area of the flow passage at the downstream end (the outlet 1013) of the second connecting portion 14 is the smallest cross-sectional area of the flow passage in the mixing cavity 1012.

[0089] In some possible embodiments, referring to FIGS. 12 and 13, the inner cavity of the first connecting portion 13 can have a constant cross-sectional area, so as to simplify the difficulty of connecting each atomization assembly 2 in the inner cavity of the first connecting portion 13, to simplify the flow channel structure of the first connecting portion 13 and thus the flow channel structure of the mixing cavity 1012, and to reduce the processing and forming difficulty of the shell 1. Of course, in some possible embodiments, referring to FIG. 14, the inner cavity of the first connecting portion 13 can also decrease along the first direction N1 without being constant. In this way, the inner walls of the first connecting portion 13 and the second connecting portion 14 are both contracted along the first direction N1, and the profile of the first connecting portion 13 and the second connecting portion 14 connected together has a smooth curvature. During the flow of the aerosol in the mixing cavity 1012, the flow rate of the aerosol is gradually accelerated under the influence of the inner walls of the first connecting portion 13 and the second connecting portion 14, so as to facilitate the aerosol to be mixed multiple times gradually, and to facilitate the aerosol to be mixed more fully.

[0090] In some embodiments, referring to FIGS. 13 and 14, the shell 1 further includes a third connecting portion 131 that encloses a contraction cavity 13, that is, the third connecting portion 131 is located above the second connecting portion 14. The inner wall cross-sectional area of the first connecting portion 13 and the inner wall cross-sectional area of the third connecting portion 131 are both constant, that is, the inner walls of the first connecting portion 13 and the third connecting portion 131 both extend along the first direction N1, and the first connecting portion 13 and the third connecting portion 131 both have simple flow channel structures, which facilitates processing and forming and reduces the processing and forming difficulty of the shell 1.

[0091] As shown in FIGS. 13 and 14, the length direction of the inner diameter of the first connecting portion 13 and the third connecting portion 131 is in the second direction. The “inner diameter of the first connecting portion 13” refers to the diameter of the flow channel enclosed by the inner wall of the first connecting portion 13, and correspondingly, the “inner diameter of the third connecting portion 131” refers to the diameter of the flow channel enclosed by the inner wall of the third connecting portion 131. It can be understood that the direction of the inner diameter of the first connecting portion 13 and the direction of the inner diameter of the third connecting portion 131 are both in a plane perpendicular to the first direction, that is, the second direction N2 is perpendicular to the first direction N1. The length direction of the inner diameter of the first connecting portion 13 is the direction of the maximum inner diameter of the first connecting portion 13, and the length direction of the inner diameter of the third connecting portion 131 is the direction of the maximum inner diameter of the third connecting portion 131, that is, the maximum inner diameter of the first connecting portion 13 and the maximum inner diameter of the third connecting portion 131 are both in the second direction N2. In the schematic diagram shown in the embodiments of the present application, N2 represents the second direction.

[0092] For ease of understanding, with reference to FIG. 14, the maximum inner diameter of the third connecting portion 131 is defined as D, and the maximum inner diameter of the first connecting portion 13 is defined as L. In some possible embodiments, with reference to FIG. 14, in the second direction N2, the ratio of the maximum inner diameter D of the third connecting portion 131 to the maximum inner diameter L of the first connecting portion 13 is greater than 4 / 5 and less than 1, that is, 4 / 5L < D < L. In the second direction N2, the inner diameter of the third connecting portion 131 is relatively large, the space for the mixed aerosol to flow into the contraction cavity 13 is large, the unit flow of the mixed aerosol introduced from the mixing cavity 1012 into the contraction cavity 13 is large, and thus large droplets are more likely to flow from the mixing cavity 1012 into the contraction cavity 13, so as to increase the sweetness of the mixed aerosol. In some possible embodiments, in the second direction N2, the ratio of the maximum inner diameter D of the third connecting portion 131 to the maximum inner diameter L of the first connecting portion 13 is greater than 0 and less than 4 / 5, that is, 0 < D < 4 / 5L. In the second direction N2, the inner diameter of the third connecting portion 131 is relatively small, the space for the mixed aerosol to flow into the contraction cavity 13 is small, the unit flow of the mixed aerosol introduced from the mixing cavity 1012 into the contraction cavity 13 is small, and thus large droplets are less likely to flow from the mixing cavity 1012 into the contraction cavity 13, so as to reduce the sweetness of the mixed aerosol, increase the flavor of the mixed aerosol, reduce the sweet and greasy feeling caused by large droplets remaining in the oral cavity, and highlight the coolness of the mouthfeel. To sum up, the user can adjust the ratio of the inner diameters of the first connecting portion 13 and the third connecting portion 131 in the second direction N2 to adjust the mouthfeel of the mixed aerosol, so as to meet the individual needs of the user. In some possible embodiments, the user can set the movable third connecting portion 131, and the third connecting portion 131 is switched between the reduced-diameter state and the enlarged-diameter state, so that the user can adjust the space for the mixed aerosol to flow into the third connecting portion 131 in real time according to the mouthfeel, so as to adjust the mouthfeel of the mixed aerosol.

[0093] In the atomizer 10 provided by the second embodiment, the atomization assembly 2 includes an inner shell 22 and an atomization tube 23. The inner shell 22 is internally provided with a sub-cavity 221, and the atomization tube 23 is arranged in the sub-cavity 221. The atomization tube 23 internally forms an airflow passage 21 and an atomization cavity 230, and the aerosol is formed in the atomization cavity 230. The above-described features in the second embodiment are the same as or similar to those in the first embodiment, and the same or similar features can be referred to each other.

[0094] The atomization cavity 230 is formed on a gas flow path of the external atmosphere. The gas flow path passes through the position where the atomization cavity 230 is located. The external atmosphere carries the aerosol in the atomization cavity 230 along a straight line during the flow process, and guides the aerosol to the mixing cavity 1012 through the airflow passage 21.

[0095] In some possible embodiments, referring to FIG. 12, the atomization pipes 23 are connected to the inner wall of the first connecting portion 13, that is, in a top view, each atomization pipe 23 is inscribedly connected to the inner wall of the first connecting portion 13, and the atomization pipe 23 is connected to the inner wall of the first connecting portion 13 in the horizontal direction. When the aerosol is guided out of the atomization pipe 23, the aerosol is not diffused in the horizontal direction, but is affected by the inner wall of the first connecting portion 13 and concentrated near the central axis of the mixing cavity 1012. The aerosol flows more smoothly into the second connecting portion 14 through the first connecting portion 13, the flow loss of the aerosol is less and the aerosol is more concentrated, which facilitates to improve the guiding efficiency of the aerosol. In some possible embodiments, referring to FIG. 14, the atomization pipes 23 are spaced apart from the inner wall of the first connecting portion 13, that is, in a top view, each atomization pipe 23 is not in contact with the inner wall of the first connecting portion 13 in the horizontal direction. The flow passage in the first connecting portion 13 has a large cross-sectional area, and when the aerosol is guided out of the atomization pipe 23, the aerosol is diffused into the inner cavity of the first connecting portion 13 in the horizontal direction. The first connecting portion 13 has a wide width in the horizontal direction, the flow of the aerosol introduced per unit time is large, and the flow velocity in the first connecting portion 13 is relatively smooth, which facilitates the mixing of a plurality of aerosols.

[0096] In some embodiments, referring to FIGS. 12, 4 and 6, the shell 1 includes a housing 101 and a base 102. After the base 102 is buckled with the housing 101, the top surface of the base 102 and the inner wall surface of the housing 101 together enclose an installation cavity 1011. The detachably connected housing 101 and base 102 together form the shell 1, which simplifies the difficulty of installing the atomization assembly 2 inside the shell 1. The base 102 is provided with an air inlet 1021 to guide the external atmosphere into the installation cavity 1011. The external atmosphere flows into the atomization assembly 2 as shown by the dashed arrows in FIG. 12, and then flows upward from bottom to top along the solid arrows in FIG. 12 by the gas flow.

The first sub-tube 231 is connected to the second sub-tube 232, and the first sub-tube 231 and the second sub-tube 232 jointly enclose the airflow channel 21. The second sub-tube 232 is connected to the mixing chamber 1012, the liquid guide 233 encloses the atomization chamber, and guides the aerosol generating substrate to the atomization chamber 230; the second sub-tube 232 is connected to the mixing chamber 1012, and the liquid guide 233 is arranged inside the first sub-tube 231 and / or the second sub-tube 232 and connected to the heating body 25. The atomizer 10 further comprises a liquid suction member 3 arranged between the housing 1 and the atomization assembly 2. The liquid suction member 3 forms a connecting channel 31 communicating with the airflow channel 21 and the mixing chamber 1012. The connecting channel 31 is coaxially arranged with the airflow channel 21, and the cross-sectional areas of the at least two connecting channels 31 are different. The above-mentioned features of the second embodiment are the same as or similar to those of the first embodiment, and the same or similar features can be referred to each other.

[0098] In some embodiments, referring to FIG. 12 and FIG. 6, the atomizer 10 further comprises a liquid storage member 4 arranged between the base 102 of the housing 1 and the atomization assembly 2, i.e. the liquid storage member 4 is located below the atomization assembly 2. The liquid storage member 4 is used for absorbing condensed liquid, and the liquid storage member 4 has a through hole 41 sleeving the heating body 25. The above-mentioned features of the second embodiment are the same as or similar to those of the first embodiment, and the same or similar features can be referred to each other.

[0099] The second embodiment of the present application also provides an electronic atomization device, as shown in FIG. 9. The electronic atomization device comprises the atomizer 10 provided by the second embodiment described above, and can be an electronic cigarette, an electronic medical atomizer, or an electronic beauty atomizer, etc. The electronic atomization device further comprises a power supply 20 electrically connected to the atomization assembly 2 in the atomizer 10.

The present application protects an electronic atomization device configured with the above-mentioned atomizer 10, so that the electronic atomization device in the present application has better mixing effect and can improve the user's actual use experience. The atomizer 10 included in the electronic atomization device described in the second embodiment is the atomizer 10 provided by the second embodiment.

[0101] The third embodiment of the present application provides an atomizer 10, which comprises a housing 1 and a plurality of atomization assemblies 2, the housing 1 is internally provided with a mounting cavity 1011 and a mixing cavity 1012, and the plurality of atomization assemblies 2 are all mounted in the mounting cavity 1011. Each atomization assembly 2 stores an aerosol generating substrate and is used for atomizing the stored aerosol generating substrate into an aerosol, and each atomization assembly 2 is internally provided with an airflow passage 21 for the flow of the aerosol.

In the schematic diagram shown in Fig. 17, the first atomization assembly 2a is provided with a first airflow passage 21a, the second atomization assembly 2b is provided with a second airflow passage 21b, the first airflow passage 21a is used for the flow of the first aerosol, the second airflow passage 21b is used for the flow of the second aerosol, the mixing cavity 1012 communicates the first airflow passage 21a and the second airflow passage 21b, the first aerosol and the second aerosol are mixed in the mixing cavity 1012, and then discharged to the outside of the mixing cavity 1012 through the outlet 1013 and finally enter the oral cavity of the user. It should be noted that the mixing cavity 1012 can be directly communicated with the oral cavity through the outlet 1013, or indirectly communicated with the oral cavity through other components, but no matter which embodiment is provided, the mixed aerosol in the mixing cavity 1012 can be discharged to the outside of the mixing cavity 1012 through the outlet 1013, but "discharged to the outside of the mixing cavity 1012 through the outlet 1013" does not mean "discharged to the outside of the atomizer 10 through the outlet 1013".

[0102] Specifically, referring to Fig. 17, the mixing cavity 1012 directly discharges the mixed aerosol to the outside of the atomizer 10 through the outlet 1013, that is, when the user consumes the aerosol, the mixing cavity 1012 directly discharges the mixed aerosol to the oral cavity through the outlet 1013, and the mixed aerosol does not need to be discharged to the oral cavity through other components, so the loss of the mixed aerosol in the process of flowing to the oral cavity is small. Moreover, the upper end of the mixing cavity 1012 does not need to be additionally provided with other components to guide the mixed aerosol into the oral cavity, which simplifies the flow channel structure in the housing 1 and facilitates the molding of the housing 1.

[0103] As shown in FIG. 17, the shell 1 is further provided with an auxiliary air passage 15 communicating with the mixing cavity 1012, the auxiliary air passage 15 being used to introduce external atmosphere into the mixing cavity 1012. The air outlet of the auxiliary air passage 15 is in the mixing cavity 1012, and the auxiliary air passage 15 is located downstream of the airflow passage 21 in the flow direction of the aerosol. The aerosol is introduced into the mixing cavity 1012 from the airflow passage 21, and the external atmosphere is introduced into the mixing cavity 1012 along the auxiliary air passage 15 on the shell 1. The aerosol and the external atmosphere are introduced into the mixing cavity 1012 at different positions respectively, and two different gas flows are generated in the mixing cavity 1012. For the convenience of understanding, the plurality of aerosols can be regarded as the first gas, and the external atmosphere can be regarded as the second gas. There are two gas flow paths in the mixing cavity 1012, and the two gas flow paths interact to form turbulent flow. The flow of the external atmosphere drives the flow of the plurality of aerosols, which can accelerate the flow of the plurality of aerosols in the mixing cavity 1012, promote the exchange of gas molecules and large droplets of the plurality of aerosols in the mixing cavity 1012, thereby improving the mixing efficiency of the plurality of aerosols, and enabling the plurality of aerosols to be better mixed.

[0104] In some possible embodiments, the blocking ribs and / or the movable wind baffles can be arranged on the portion (the mouthpiece 16) of the shell 1 that encloses the mixing cavity 1012, and the blocking ribs and the wind baffles are arranged downstream of the flow direction of the aerosol to collide the aerosols in the first direction N1. The blocking ribs and the wind baffles collide the aerosols to make the aerosols form collision turbulent flow more quickly in the mixing cavity 1012, and then make the aerosols be more fully mixed in the mixing cavity 1012. The wind baffles are movably arranged, so that the flow direction of the aerosols can be adjusted, and / or the flow speed of the aerosols can be changed, to improve the mixing effect of the aerosols and meet the individualized needs of the user.

[0105] The nebulizer 10 provided by the third embodiment of the present application comprises a shell 1 and a plurality of nebulization assemblies 2, the shell 1 is internally provided with a mounting cavity 1011 and a mixing cavity 1012, and the plurality of nebulization assemblies 2 are all mounted in the mounting cavity 1011. Each nebulization assembly 2 stores an aerosol generating substrate and is used for nebulizing the stored aerosol generating substrate into aerosols, and each nebulization assembly 2 is internally provided with an airflow channel 21 for the flow of aerosols. In the first direction N1, one end of the mixing cavity 1012 communicates with each airflow channel 21, so as to mix the aerosols discharged by each airflow channel 21; the other end of the mixing cavity 1012 forms an outlet 1013 for discharging the mixed aerosols. Wherein, the shell 1 is further provided with an auxiliary air passage 15 communicating with the mixing cavity 1012, the auxiliary air passage 15 is used for introducing external atmosphere into the mixing cavity 1012, and the aerosols and the external atmosphere are introduced into the mixing cavity 1012 at different positions respectively, two gas flows are generated in the mixing cavity 1012, the two gases influence each other on the flow path, a turbulent flow is formed in the mixing cavity 1012, the flow of the external atmosphere promotes the exchange of gas molecules and large droplets among the plurality of aerosols in the mixing cavity 1012, and the mixing efficiency of the plurality of aerosols is increased, thereby improving the effect of the nebulizer 10 on mixing the plurality of aerosols and reducing the taste stratification generated by the user when eating the plurality of aerosols.

[0106] In some embodiments, as shown in FIG. 17, the cross-sectional areas of at least two airflow channels 21 are different, for example, the atomizer 10 is provided with three airflow channels 21, and it can be understood that the cross-sectional areas of the three airflow channels 21 can all be different, or the cross-sectional areas of two of the three airflow channels 21 can be different. In the embodiment shown in the schematic diagram of the present application, the housing 1 is provided with two airflow channels 21, and the cross-sectional areas of the first airflow channel 21a and the second airflow channel 21b are different. The cross-sectional direction is perpendicular to the first direction N1, and as previously known, the first direction N1 is the flow direction of the aerosol. Therefore, the cross section perpendicular to the first direction N1 is the flow passage cross section formed by the inner wall of the airflow channel 21. In FIG. 17, the first direction N1 is substantially vertical, and therefore the flow passage cross section is substantially horizontal. According to Bernoulli's principle, the flow rate and flow volume of the fluid are related to the flow passage cross-sectional area. The aerosol generating substrates in each atomization assembly 2 are different, and therefore the aerosol output or aerosol output time in each atomization assembly 2 is also different. For example, the first aerosol in the first atomization assembly 2a has a larger output, and the second aerosol in the second atomization assembly 2b has a smaller output. Therefore, the cross-sectional area of the first airflow channel 21a is smaller than that of the second airflow channel 21b, so as to balance the flow rate and flow volume of the first aerosol and the second aerosol, control the time when the first aerosol and the second aerosol reach the mixing chamber 1012, and control the flow volume of the first aerosol and the second aerosol introduced into the mixing chamber 1012 per unit time, so that the two aerosols can be introduced into the mixing chamber 1012 simultaneously and uniformly, which is easy to achieve, and facilitates the uniform mixing of various aerosols, and further improves the mixing effect of the atomizer 10.

[0107] In some embodiments, as shown in FIG. 19, the cross-sectional area of the mixing cavity 1012 is constant, i.e., the cross-sectional area of each part of the mixing cavity 1012 is a fixed value, for example, the cross-sectional area at the outlet 1013 is equal to the cross-sectional area of the flow channel at any part of the mixing cavity 1012. That is, the inner wall surface surrounding the mixing cavity 1012 is parallel to the first direction N1, and the extension of the inner wall surface surrounding the mixing cavity 1012 is a straight line parallel to the first direction N1 on the cross section (the cross section with cross section lines in FIG. 19) in the first direction N1. The mixing cavity 1012 has a simple inner wall surface and forms a relatively simple flow channel structure, so that the flow channel structure inside the atomizer 10 is relatively simple, and the processing and molding difficulty of the shell 1 is also reduced. It should be noted that if the aerosol contains a sweetener, the boiling point, type and taste of the aerosol generating substrate will affect the proportion of large droplets (large droplet content / ingredient aerosol content) in the generated aerosol, thereby affecting the taste of the aerosol. In the case of a large proportion of large droplets, the aerosol tastes sweet; in the case of a small proportion of large droplets, the aerosol tastes sweet. The cross-sectional area of the mixing cavity 1012 is constant, so that each aerosol in the mixing cavity 1012 has a simple flow path, reducing the collision effect of the inner wall of the mixing cavity 1012 on the aerosol, so that the mixed aerosol is not blocked and is directly guided out through the outlet 1013, which is beneficial to reduce the loss of large droplets in the mixed aerosol and maintain the sweetness of the mixed aerosol.

[0108] In some embodiments, as shown in FIGS. 17 and 20, the portion of the housing 1 that encloses the mixing chamber 1012 includes a mixing portion 161 connected to a converging portion 162, one end of the mixing portion 161 is connected to the atomization assembly 2, and the other end of the mixing portion 161 is connected to the converging portion 162, and the outlet 1013 is formed at the end of the converging portion 162 away from the mixing portion 161, that is, the mixing portion 161 is located above the atomization assembly 2, and the converging portion 162 is located above the mixing portion 161. Among the mixing portion 161 and the converging portion 162, at least the inner cavity cross-sectional area of the mixing portion 161 decreases along the first direction N1, which can be that the inner cavity cross-sectional area of both the mixing portion 161 and the converging portion 162 decreases along the first direction N1, or only the inner cavity cross-sectional area of the mixing portion 161 decreases along the first direction N1. According to Bernoulli's principle, the smaller the flow passage cross-sectional area, the faster the fluid flow rate. When the inner cavity cross-sectional area of both the mixing portion 161 and the converging portion 162 decreases along the first direction N1, the contour formed by the inner walls of the mixing portion 161 and the converging portion 162 has a smooth curvature. During the flow of aerosols in the mixing chamber 1012, the flow rate gradually increases under the influence of the inner walls of the mixing portion 161 and the converging portion 162, and each aerosol gradually mixes multiple times, which facilitates the mixing of each aerosol. When only the inner cavity cross-sectional area of the mixing portion 161 decreases along the first direction N1 (as shown in FIG. 20), the inner cavity cross-sectional area of the converging portion 162 can increase or decrease along the first direction N1, or the inner cavity cross-sectional area of the converging portion 162 can be constant. However, regardless of the structure of the inner walls of the converging portion 162 and the mixing portion 161, at least the inner cavity cross-sectional area of the mixing portion 161 decreases along the first direction N1, that is, along the first direction N1, the flow passage formed by the mixing portion 161 is narrow at the top and wide at the bottom, so as to block the flow of aerosols by the inner walls and change the flow direction of the aerosols, so that multiple aerosols converge towards the central axis Z of the mixing chamber 1012, and the mixing of multiple aerosols is achieved. In addition, the position with a smaller cross-sectional area of the mixing portion 161 generates a larger pressure, which can promote the flow of aerosols to facilitate the exchange of gas molecules and large droplets among multiple aerosols, and facilitate the mixing of multiple aerosols.

[0109] Specifically, as shown in FIGS. 17, 18 and 20, the housing 1 includes a mouthpiece 16 and a shell 15, the mouthpiece 16 forms the mixing portion 161 and the converging portion 162, the inner wall of the shell 15 encloses the mounting chamber 1011, and the inner wall of the mouthpiece 16 encloses the mixing chamber 1012. The mixing portion 161 and the converging portion 162 are provided on the same component, and there is no assembly gap between the mixing portion 161 and the converging portion 162. The sealing structure for filling the assembly gap between the mixing portion 161 and the converging portion 162 is omitted, the structure of the atomizer 10 is relatively simple, and the assembly operation of the atomizer 10 is simplified.

[0110] In some embodiments, as shown in FIG. 17 and FIG. 20, the auxiliary air passage 15 is formed at one end of the mixing portion 161 connected to the atomization assembly 2, i.e. the auxiliary air passage 15 is formed at the lower end of the mixing portion 161. In the mixing cavity 1012, the auxiliary air passage 15 is located upstream of the aerosol flow direction, and the outlet 1013 is located downstream of the aerosol flow direction. Compared with setting the auxiliary air passage 15 at the contraction portion 162 or other positions of the mixing portion 161, the auxiliary air passage 15 is located at the lower end of the mixing portion 161 and is far away from the outlet 1013, so that the external atmosphere can act on the path of the aerosol, which is beneficial to the mixing of multiple aerosols in a longer path. In addition, the auxiliary air passage 15 is formed at a position (lower end) with a larger cross-sectional area of the flow passage in the mixing portion 161. Under the influence of the external atmosphere introduced by the auxiliary air passage 15, the aerosol flows to a position (upper end) with a smaller cross-sectional area of the flow passage in the mixing portion 161. Multiple aerosols collide on the inner wall at the upper end of the mixing cavity 1012, forming a turbulent flow that converges to the central axis Z of the mixing cavity 1012, thereby achieving mixing.

[0111] In some embodiments, as shown in FIG. 17 and FIG. 20, the auxiliary air passage 15 is provided with multiple auxiliary air passages, each air flow passage 21 is communicated with at least one auxiliary air passage 15, and the gas outlet of the auxiliary air passage 15 is communicated with the air flow passage 21. The number of auxiliary air passages 15 can be greater than the number of air flow passages 21, and the number of auxiliary air passages 15 can also be equal to the number of air flow passages 21, as long as one air flow passage 21 is communicated with at least one auxiliary air passage 15. The auxiliary air passages 15 collectively introduce external atmosphere to the mixing cavity 1012 at multiple positions and act on the aerosols discharged by all air flow passages 21. Multiple aerosols are affected by the external atmosphere, so that the content of each aerosol in the mixed aerosol is approximately equal, and multiple aerosols are uniformly mixed into a mixed aerosol, further reducing the taste stratification.

[0112] In some embodiments, as shown in FIG. 17 and FIG. 20, the auxiliary air passage 15 is located on the side of the airflow passage 21 away from the mixing cavity 1012 in the second direction, i.e., the auxiliary air passage 15 is located on the side of the airflow passage 21 away from the central axis Z of the mixing cavity 1012. Here, the second direction is perpendicular to the first direction N1, and the second direction is the direction of the cross section of the flow passage. The first direction N1 is the height direction of the atomizer 10 in the normal use of the three-dimensional coordinate system, and the second direction is the direction of the length and width dimensions of the atomizer 10 in the normal use of the three-dimensional coordinate system. For ease of understanding, the second direction can be simply understood as the left-right direction shown in FIG. 17 and FIG. 20. In FIG. 17 and FIG. 20, the walls of the first airflow passage 21a and the second airflow passage 21b are tangent to the inner wall of the mixing cavity 1012. The first auxiliary air passage 15a is located on the left side of the first airflow passage 21a to drive the first kind of aerosol guided by the first airflow passage 21a to flow from left to right towards the central axis Z. The second auxiliary air passage 15b is located on the right side of the second airflow passage 21b to drive the second kind of aerosol guided by the second airflow passage 21b to flow from right to left towards the central axis Z. The external atmosphere guided by the first auxiliary air passage 15a blocks the first kind of aerosol from diffusing to the left, and the external atmosphere guided by the second auxiliary air passage 15b blocks the second kind of aerosol from diffusing to the right. The first kind of aerosol and the second kind of aerosol converge near the central axis Z to form a mixed aerosol with sufficient mixing.

[0113] In some embodiments, as shown in FIG. 17 and FIG. 20, the auxiliary air passage 15 guides the external atmosphere in the third direction, and the angle between the third direction and the first direction N1 is greater than or equal to 90 degrees and less than or equal to 135 degrees, i.e., the auxiliary air passage 15 is inclined downward, and the air outlet of the auxiliary air passage 15 is located at the lower end. It can be understood that the user intermittently consumes aerosol, and at the moment when the consumption of aerosol is stopped, the bottom of the airflow passage 21 is in a negative pressure state, and part of the aerosol flows in the direction away from the outlet 1013, i.e., the aerosol is sucked back. The auxiliary air passage 15 is inclined downward, so that the air inlet of the auxiliary air passage 15 is located at the end of the auxiliary air passage 15 away from the direction of aerosol backflow. This can reduce the possibility of aerosol flowing into the assembly gap inside the atomizer 10 from the air inlet of the auxiliary air passage 15 when the aerosol is sucked back, thereby reducing the possibility of aerosol remaining in the assembly gap inside the atomizer 10, and facilitating the extension of the service life of the atomizer 10.

[0114] In some embodiments, as shown in FIG. 17, FIG. 18 and FIG. 21, the atomization assembly 2 comprises an inner shell 22 and an atomization tube 23. The inner shell 22 is internally provided with a sub-cavity 221, and the atomization tube 23 is arranged in the sub-cavity 221.

[0115] The atomization cavity 230 is formed on the gas flow path of the external atmosphere, the gas flow path passes through the position where the atomization cavity 230 is located, and the external atmosphere carries the aerosol in the atomization cavity 230 along a straight line during the flow process and guides the aerosol to the mixing cavity 1012 through the airflow channel 21.

[0116] As shown in FIGS. 17, 18 and 21, the outer shell 1 is sleeved on the inner shell 22, the outer shell 1 is formed with the air inlet 17 which communicates the external environment and each airflow channel 21, and the gap between the outer shell 1 and the inner shell 22 forms the air inlet channel 5 which communicates the air inlet 17 and the auxiliary air passage 15. It can be understood that part of the external atmosphere introduced from the air inlet 17 is guided to the auxiliary air passage 15 through the air inlet channel 5, and the other part is introduced into each airflow channel 21 and drives the aerosol in each airflow channel 21 to flow to the mixing cavity 1012 for mixing. The air inlet 17 and the air inlet channel 5 are defined as the auxiliary flow path of the auxiliary air passage 15. In this way, the air inlet 17 for introducing the external atmosphere into the airflow channel 21 can be used as the air inlet position of the air inlet channel 5, and there is no need to additionally open the air inlet position of the air inlet channel 5. The sleeving gap between the outer shell 1 and the inner shell 22 can be used as the air inlet channel 5 for guiding the external atmosphere into the auxiliary air passage 15, and there is no need to process and form the gas flow channel inside the outer shell 1. The auxiliary flow path structure communicating the auxiliary air passage 15 is simple, which reduces the processing and forming difficulty of the auxiliary flow path in the atomizer 10 and facilitates implementation.

[0117] In some embodiments, as shown in FIGS. 17 and 21, the atomization assembly 2 further comprises a heating body 25 for atomizing the aerosol generating substrate into aerosol, and at least one heating body 25 is arranged in each atomization tube 23. The atomization tube 23 comprises a first sub-tube 231, a second sub-tube 232 and a liquid guide 233, the first sub-tube 231 is connected to the second sub-tube 232, and the first sub-tube 231 and the second sub-tube 232 jointly enclose the airflow channel 21. The second sub-tube 232 is connected to the mixing cavity 1012, the liquid guide 233 encloses the atomization cavity and guides the aerosol generating substrate to the atomization cavity 230; the second sub-tube 232 is connected to the mixing cavity 1012, and the liquid guide 233 is arranged inside the first sub-tube 231 and / or the second sub-tube 232 and connected to the heating body 25. The atomizer 10 further comprises a liquid suction member 3, which is arranged between the outer shell 1 and the atomization assembly 2, and the liquid suction member 3 is formed with a connecting channel 31 which communicates the airflow channel 21 and the mixing cavity 1012. The connecting channel 31 is coaxially arranged with the airflow channel 21, and the cross-sectional areas of at least two connecting channels 31 are different. The above-mentioned features in the second embodiment are the same as or similar to those in the first and second embodiments, and they can be referred to each other.

[0118] The electronic atomization device can be an electronic cigarette, an electronic medical atomizer 10, or an electronic beauty atomizer 10, etc. As shown in FIGS. 3 and 4, the electronic atomization device comprises the atomizer 10 described above. Since the electronic atomization device provided by the embodiment of the present application comprises the atomizer 10 provided by any of the embodiments described above, it has the same technical effects, i.e., it has the advantages of high mixing efficiency, sufficient mixing, good mixing effect, and reduced taste stratification.

[0119] As shown in FIGS. 3 and 4, the electronic atomization device further comprises a power supply 20 and a liquid storage member 4. The power supply 20 is installed in the installation cavity 1011 and is located below the atomization assembly 2. The power supply 20 is used to supply power to the atomization assembly 2 in the atomizer 10 to drive the atomization assembly 2 to work. The power supply 20 and each atomization assembly 2 are jointly installed in the installation cavity 1011. The shell 1 simultaneously covers the battery pack and each atomization assembly 2. There is no need to additionally set a part to cover the battery pack, and there is no need to set a connecting structure to cover the part and the shell 1. Therefore, the assembly difficulty of the electronic atomization device is simplified. In addition, the shell 1 has a relatively complete contour boundary, so that the airtightness of the installation cavity 1011 is relatively high, and the possibility of external atmosphere overflowing in the installation cavity 1011 is reduced. The type of battery in the power supply 20 is not limited in the present application. For example, the power supply can be a lithium battery. The atomizer 10 comprised by the electronic atomization device of the third embodiment is the atomizer 10 provided by the third embodiment.

[0120] It should be noted that the power supply 20 in the third embodiment is different from the power supply 20 in the first and second embodiments. As shown in FIGS. 9 and 17, it can be understood that the power supply 20 in the first and second embodiments is located outside the installation cavity 1011, while the power supply 20 in the third embodiment is located inside the installation cavity 1011.

[0121] As shown in FIGS. 3 and 4, the liquid storage member 4 is at least used to absorb condensed liquid. In the first direction N1, the liquid storage member 4 is arranged between the power supply 20 and the atomization assembly 2, i.e., the liquid storage member 4 is arranged below the atomization assembly 2. The liquid storage member 4 is provided with a through hole 41 which is in communication with the airflow channel 21 and is used to guide external atmosphere into the airflow channel 21.

Alternatively, one liquid storage member 4 can be arranged below the atomization assembly 2, and the liquid storage member 4 has a plurality of through holes 41. Regardless of the structure of the liquid storage member 4, as long as each airflow channel 21 is in communication with one through hole 41.

[0122] Specifically, as shown in FIG. 3 and FIG. 4, the lower part of the atomization assembly 2 is provided with a liquid storage member 4, which is installed on the battery pack. The liquid storage member 4 is provided with a plurality of through holes 41, each of which is communicated with an airflow channel 21. Further, the electrical connecting member 252 in the heating body 25 is arranged above the liquid storage member 4. After the atomizer 10 is closed, the electrical connecting member 252 and the battery pack are cooled to generate condensate. The liquid storage member 4 absorbs the condensate generated by the electrical connecting member 252 and the power supply 20, so as to reduce the risk of short circuit of the electrical connecting member 252 and the power supply 20 caused by the condensate.

[0123] In some possible embodiments, as shown in FIG. 3 and FIG. 4, the air inlet 17 on the shell 1 is located below the battery pack. After the air inlet 17 on the shell 1 introduces the external atmosphere, the external atmosphere flows from the lower part to the upper part along the first direction N1. The heat on the surface of the power supply 20 can be taken away by the gas flow, so as to reduce the heat accumulation on the surface of the power supply 20.

Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
