It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, further discussion thereof is not required in subsequent figures.

With reference to fig. 1-13, embodiments of the present application provide an electronic aerosolization assembly comprising:

casing 1, lower base 2, upper cover 3 and atomizing core subassembly, and be located stock solution storehouse 10 in the casing 1. The shell 1 can be made of elastic semitransparent or transparent materials, and an air outlet channel 11 communicated with the outside is arranged on the shell 1; the lower base 2 and the shell 1 are connected in a matched mode to form an accommodating cavity, and an air inlet channel 21 communicated with the outside is formed in the lower base 2.

Referring to fig. 7 to 11, the upper cover 3 is disposed in the accommodating cavity, the upper cover 3 includes an upper cover body 30 and a top cover 300 located on the top of the upper cover body 30, the top cover 300 has a through hole 301, the upper cover body 30 has a flow guide structure 31 opposite to the through hole 301, the flow guide structure 31 and the inner wall of the housing 1 enclose a synthesis gas flow channel, the gas flow channel is communicated with the through hole 301, and a protrusion 32 is disposed on a side of the flow guide structure 31 facing the through hole 301;

atomizing core subassembly set up in upper cover body 30 with between base 2 down, atomizing core subassembly has the orientation the atomizing face of base 2 down, the atomizing face with form atomizing chamber 20 down between the base 2, atomizing chamber 20 with inlet channel 21 intercommunication, and pass through airflow channel with through-hole 301 with outlet channel 11 intercommunication.

Specifically, since the air flow channel and the through hole 301 are both communicated with the air outlet channel 11, the external air entering from the air inlet channel 21 can carry the atomized aerosol in the atomizing cavity 20 to flow to the air flow channel, and then the atomized aerosol passes through the through hole 301 and is inhaled by the user through the air outlet channel 11, and when the atomized aerosol passing through the air flow channel flows into the air outlet channel 11 through the through hole 301, the air flow velocity of the atomized aerosol is too high due to the narrow flow space of the air flow channel; the airflow formed by the atomized aerosol collides with the protrusions 32 when flowing through the through holes 301, so that the flow speed of the atomized aerosol is reduced, the phenomenon that the airflow of the atomized aerosol sucked by a user is too large is avoided, and the sucking experience of the user is ensured; meanwhile, part of condensate may be generated after the flow rate of the atomized aerosol is slowed down, and the protrusion 32 may guide the condensate, so that the condensate flows back into the atomizing chamber 20, and a user is prevented from inhaling the condensate.

Furthermore, after the protrusions 32 collide with the atomized aerosol with too high flow velocity, the flow velocity of the atomized aerosol can be kept in a uniform or slow acceleration and deceleration state, so that the flowing smoothness of the atomized aerosol is improved, the problem of 'adsorption' or 'sedimentation' caused by the speed difference between large-particle atomized aerosol and medium-particle atomized aerosol due to the sharp increase or decrease of the flow area of the atomized aerosol is solved, the accumulation of condensate generated after the atomized aerosol is 'adsorbed' or 'sedimentation' is reduced, and the suction experience of users is improved. In addition, the number of the protrusions 32 may be one or more, the number of the protrusions 32 may be one, and the protrusions may be opposite to the through holes 301, and the number of the protrusions 32 may be multiple, and the protrusions may be distributed in an array on one side of the flow guide structure 31 facing the through holes 301, or may be centrally disposed at a position where the flow guide structure 31 is opposite to the through holes 301.

The electronic cigarette atomization assembly provided by the embodiment of the application comprises a shell 1, a lower base 2, an upper cover 3 and an atomization core assembly, wherein an air outlet channel 11 communicated with the outside is arranged on the shell 1; lower base 2 with 1 cooperation of casing is connected and is formed and hold the chamber, upper cover 3 set up in hold the intracavity, have on the upper cover body 30 with the water conservancy diversion structure 31 that through-hole 301 is relative, water conservancy diversion structure 31 with 1 inner wall of casing encloses synthetic airflow channel, airflow channel with through-hole 301 intercommunication, water conservancy diversion structure 31's orientation one side of through-hole 301 is provided with protruding 32, atomizing chamber 20 with inlet channel 21 intercommunication, and pass through airflow channel with through-hole 301 with outlet channel 11 intercommunication. The atomizing aerosol airflow generated in the atomizing cavity 20 flows through the through hole 301, and collides with the protrusion 32 and decelerates, so that the flow speed of the atomizing aerosol is slowed down, the atomizing aerosol airflow sucked by a user is prevented from being too large, and the sucking experience of the user is guaranteed.

Optionally, the protrusion 32 is one of a small hemisphere, a large hemisphere, and a polyhedron.

Specifically, the protrusion 32 may be at least partially spherical, for example, the protrusion 32 may be a little hemisphere, a hemisphere or a more hemisphere, so that the outer surface of the protrusion 32 may be a cambered surface. The atomizing aerosol airflow generated in the atomizing cavity 20 flows through the through hole 301 and collides with the protrusion 32, so that the airflow of the atomizing aerosol is prevented from being suddenly reduced under the condition of buffering the atomizing aerosol airflow, and the flow speed stability of the atomizing aerosol is ensured. In order to buffer the atomized aerosol of the flow guide structure 31 in a targeted manner, the protrusions 32 may be polyhedral, for example, the protrusions 32 may be tetrahedral, pentahedral or hexahedral, and the tetrahedral or hexahedral protrusions 32 may include two symmetrical surfaces, which may buffer the atomized aerosol on two sides of the flow guide structure 31 respectively.

Optionally, the protrusion 32 is a hemisphere, and the radius of the hemisphere ranges from 0.2mm to 1.5 mm.

Specifically, when the protrusion 32 is a hemisphere, the maximum cross section of the protrusion 32 (that is, the sphere passes through the center of the sphere) may be connected to the flow guiding structure 31, and specifically, the protrusion may be bonded separately or formed integrally to ensure the stability of the protrusion 32. The radius of the hemisphere directly influences the collision area and the buffering effect with the atomized aerosol airflow. For example, the radius of the hemisphere is too small, only a small part of the atomized aerosol airflow can collide with the protrusion 32, and most of the high-speed airflow flows to the air outlet channel 11 through the through hole 301, so that the smoking experience of the user is affected; and the radius of hemisphere is too big, can occupy more atomizing aerosol's circulation space on the one hand, and on the other hand can cause atomizing aerosol airflow velocity's quick reduction, causes atomizing aerosol airflow to reduce and atomizing aerosol condensation is the problem of condensate.

Optionally, the flow guide structure 31 includes a planar portion and symmetrically disposed inclined portions on both sides of the planar portion, the inclined portions bend in the direction of the atomizing core assembly, and the protrusions 32 are disposed on the planar portion.

Specifically, the inclined portion can form a streamlined extension structure, and the joint of the inclined portion and the planar portion can be smooth and smooth, so that atomized aerosol passing through the airflow channel can smoothly and stably flow to the through hole 301, and airflow smoothness of the electronic cigarette atomization assembly is guaranteed.

In a specific embodiment, as shown in fig. 7, the flow guiding structure 31 has a saddle shape, and specifically includes a planar portion disposed on the top of the flow guiding structure 31 and arc portions connected to both sides of the planar portion, that is, the inclined portions. The saddle-shaped flow guiding structure 31 forms a smooth and slippery surface, ensuring the smoothness and stability of the atomized aerosol passing through the airflow channel.

Optionally, the protrusion 32 is disposed toward the through hole 301.

Specifically, the external air entering from the air inlet channel 21 may carry the atomized aerosol in the atomizing cavity 20 to flow toward the surface of the flow guide structure 31, and collide with the protrusions 32 on the surface of the flow guide structure 31, so that the flow direction of the atomized aerosol changes, and then the atomized aerosol passes through the through hole 301 and is inhaled by the user through the air outlet channel 11. After the protrusion 32 is arranged towards the through hole 301, the atomized aerosol can flow towards the through hole 301 after colliding with the protrusion 32, so that the smoothness of the flow of the atomized aerosol is improved.

Optionally, the airflow channel includes a single-side airflow channel and an opposite-side airflow channel, and the two inclined portions respectively enclose the inner wall of the housing 1 to form the single-side airflow channel and the opposite-side airflow channel.

Specifically, after the inclined portions are arranged on two sides of the planar portion of the flow guide structure 31, airflow channels may be formed between the inclined portions on two sides and the housing 1, specifically, two inclined portions are respectively enclosed with the inner wall of the housing 1 to form the single-side airflow channel and the opposite-side airflow channel, preferably, the single-side airflow channel and the opposite-side airflow channel may be symmetrically arranged on two sides of the flow guide structure 31, so as to improve the balance and stability of aerosol flowing in the airflow channels.

In a specific embodiment, the protrusion 32 is formed with a first side facing the single-side airflow channel and a second side facing the opposite-side airflow channel, and the first side and the second side are both curved surfaces that are concave, that is, the first side is concave in a direction away from the single-side airflow channel, and the second side is concave in a direction away from the opposite-side airflow channel. Make pass through unilateral air flow channel with the atomizing aerosol of offside air flow channel can be respectively first side with the flow direction on the second side changes, moreover first side with the inside sunken cambered surface can play the cushioning effect for atomizing aerosol's flow direction change, avoids atomizing aerosol that the velocity of flow of atomizing aerosol takes place sharp change and brings to condense scheduling problem, has guaranteed electron smog atomization component's atomization effect.

Optionally, the height of the protrusions 32 ranges from 0.2mm to 1.5 mm.

In particular, the height of the protrusions 32 directly affects the impact area and the damping effect with the aerosol gas flow. For example, when the height of the protrusion 32 is too small, only a small part of the atomized aerosol airflow can collide with the protrusion 32, and a large part of the high-speed airflow flows to the air outlet channel 11 through the through hole 301, which affects the smoking experience of the user; and when the height of arch 32 was too big, on the one hand can occupy more atomizing aerosol's circulation space, and on the other hand can cause atomizing aerosol airflow velocity's quick reduction, causes atomizing aerosol airflow to reduce and atomizing aerosol condensation is the problem of condensate.

Alternatively, referring to fig. 7 and 11, a side of the inclined portion away from the planar portion has a rounded chamfer having a radius in the range of 0.1mm to 0.5 mm.

Specifically, when the atomized aerosol in the atomizing chamber 20 flows from the airflow channel to the through hole 301, the atomized aerosol first flows through the surface of the inclined portion through the side of the inclined portion away from the planar portion, and then flows to the planar portion, and finally flows to the through hole 301 under the guiding action of the protrusions 32 on the planar portion. Since a narrow gap is formed between the side of the inclined portion away from the planar portion and the housing 1, the flow of the atomized aerosol is obstructed. The arrangement of the round chamfer can increase the inlet space between the inclined part and the shell 1, and improve the smoothness of the flow of the atomized aerosol. The radius of the round chamfer can be determined according to the flow and flow speed requirements of the atomized aerosol circulation. For example, when the flow and the flow speed of the atomized aerosol are large, the smoothness of the atomized aerosol can be improved by arranging the round chamfer with a large radius; when the flow and the flow speed of the atomized aerosol are small, the stability of the atomized aerosol circulation can be ensured by arranging the round chamfer with small radius.

Optionally, referring to fig. 4, the intake air in the intake channel 21 passes through the airflow channel and then is output from the outlet channel 11, and the airflow channel sequentially includes a first airflow channel B, a second airflow channel C, a third airflow channel D, and a fourth airflow channel E along the flow direction of the airflow channel;

the first section of air flow channel B is located in the atomizing cavity 20, the third section of air flow channel D is located between the flow guide structure 31 and the through hole 301, and the fourth section of air flow channel E is located in the air outlet channel 11;

Specifically, referring to fig. 4, when a user sucks the electronic cigarette atomization assembly provided in the embodiment of the present application, external air firstly passes through the air inlet channel a (i.e., the air inlet channel 21), and since the air flow passes through the air inlet channel a without much structural obstruction, the air flow enters the first section of the air flow channel B (i.e., the atomization chamber 20) in a more moderate state, and meanwhile, since the cross-sectional area of the first section of the air flow channel B is larger, the pressure change of the air flow when passing through is not obvious; then the mixed airflow formed after the air airflow is mixed with the atomized aerosol in the atomization cavity enters a second section of airflow channel C through a flow guide structure 31 with a certain fillet, the airflow is gradually accelerated due to the slow reduction of the overflowing area of the second section of airflow channel C, but the speed of the mixed airflow gradually tends to be stable due to the large length of the second section of airflow channel C, then the mixed airflow passes through a third section of airflow channel D, the overflowing area is reduced due to a protrusion 32 in the third section of airflow channel D, the speed of the mixed airflow is slowed down, and the mixed airflow is guided, so that the mixed airflow smoothly flows to a fourth section of airflow channel E (namely an air outlet channel 11), meanwhile, the structure of the protrusion 32 can also guide the condensate, and the condensate is prevented from being sucked out by a smoker after being accumulated.

Overall, when the flow area ratio range between the four air flow channels, namely the first section air flow channel B, the second section air flow channel C, the third section air flow channel D and the fourth section air flow channel E, between the adjacent air flow channels is controlled within 0.75-1.25, the atomized aerosol in the air flow channel of the electronic aerosol atomization assembly can keep a relatively stable flow velocity when the atomized aerosol circulates between the adjacent air flow channels, and the change of the air flow in the flowing process is not obvious, so that the mixing state of the atomized aerosol particles and the air flow can be ensured to be relatively stable, and the user suction experience is improved.

Optionally, the minimum flow area of a communication channel formed by the communication of the first section of the airflow channel B, the second section of the airflow channel C and the third section of the airflow channel D is greater than or equal to 80% of the maximum flow area.

Specifically, the proportion of the minimum flow area to the maximum flow area in a communication channel formed by communicating the first section of airflow channel B, the second section of airflow channel C and the third section of airflow channel D is controlled, so that the sudden change of the flow section of the communication channel can be avoided, the change of the flow velocity of atomized aerosol caused by the change of the whole flow area in the airflow channel is weakened, the flow velocity of the airflow in the communication channel is stable, the mixing state of atomized aerosol particles and the airflow can be ensured to be stable, most of the generated aerosol can enter the mouth of a smoker, the generation of condensate in the smoke bomb is reduced, and the smoking experience of a user is improved.

Further, the minimum flow area in the airflow passage is greater than or equal to 66.7% of the maximum flow area. Since the fourth section of air flow channel E is located in the air outlet channel 11, the flow area of the air outlet channel 11 can be set smaller for the convenience of the user to suck. However, in order to avoid aerosol condensation caused by the abrupt change of the flow area in the flow channel, the minimum flow area in the flow channel may be set to be greater than or equal to 66.7% of the maximum flow area, for example, the minimum flow area of the fourth flow channel E is set to be greater than or equal to the maximum flow area in a communication channel formed by the first flow channel B, the second flow channel C and the third flow channel D.

Optionally, referring to fig. 2 to 4, the second segment of the airflow channel C comprises a first airflow channel C1 and a second airflow channel C2, the first airflow channel C1 is located between the atomizing core assembly and the inner wall of the housing 1, and the second airflow channel C2 is located between the flow guide structure 31 and the inner wall of the housing 1;

the ratio of the passage length of the first air flow passage C1 to the second air flow passage C2 ranges from 0.8 to 1.2.

Specifically, the atomizing core assembly may be connected to a side of the upper cover body 30 close to the lower base 2, and the airflow passage C is formed between the atomizing core assembly and the upper cover body 30 and the housing 1. Since the sectional size of the atomizing core assembly is smaller than that of the upper cover body 30, the flow section of the first air flow passage C1 is larger than that of the second air flow passage C2. The atomized aerosol in the atomizing chamber 20 passes through the first air flow channel C1 and the second air flow channel C2 in sequence, and the channel length ratio of the first air flow channel C1 to the second air flow channel C2 has a direct influence on the air flow rate and the wall surface adsorption degree of the atomized aerosol; when the ratio of the channel lengths of the first air flow channel C1 and the second air flow channel C2 is too small, the length of the first air flow channel C1 is also too small, and the atomized aerosol in the atomizing chamber 20 directly enters the second air flow channel C2 with a smaller cross section, which brings obstruction to the flow of the atomized aerosol; when the ratio of the channel lengths of the first air flow channel C1 and the second air flow channel C2 is too large, the channel length of the second air flow channel C2 is too short, and the size of the inclined portion is reduced, which is not favorable for transition of the atomized aerosol to the planar portion.

Alternatively, the size of the cross section of the gas outlet channel 11 in the gas outlet direction is kept constant.

Specifically, the cross-sectional size of the air outlet channel flow of traditional electron cigarette along its direction of giving vent to anger is crescent, can make atomizing aerosol further slowed down before the user inhales, and atomizing aerosol temperature at this moment is lower moreover, and too much atomizing aerosol particle subsides easily at air outlet channel's wall, piles up after certain degree as the condensate on the air outlet channel wall, and the user is very easily with these condensate suction nozzles when the suction, very influences user's the experience of taking out food. And the embodiment of the application provides the cross-sectional size of air outlet channel 11 along the direction of giving vent to anger of electron smog subassembly keeps unchangeable, can make atomizing aerosol flow rate before the user inhales keep unchangeable, and the settling and the piling up of condensate on the air outlet channel 11 wall can be avoided to steady atomizing aerosol's air current, has guaranteed user's suction experience.

Or alternatively, the section of the air outlet channel 11 along the air outlet direction is gradually reduced, so that the flow rate of the atomized aerosol before the user inhales is slightly increased, and the efficiency of the user for inhaling the atomized aerosol is increased. The cross section of the air outlet channel 11 may be a cylinder or an elliptic cylinder, which is not limited in the embodiments of the present application.

Optionally, the axial section of the air outlet channel 11 is conical, and an included angle between the inclined plane of the cone and the axis is 0-2 °.

Specifically, the axial direction of the gas outlet channel 11 is the flowing direction of the gas flow in the gas outlet channel 11, such as the direction from bottom to top in fig. 13. The degree of gradual reduction of the section of the air outlet channel 11 along the air outlet direction is reflected by the size of the included angle between the conical inclined plane and the axis of the air outlet channel 11. When the section of the air outlet channel 11 along the air outlet direction is gradually reduced to an excessively large extent, the flow rate of the atomized aerosol in the air outlet channel 11 can be remarkably increased, the stable flow of the atomized aerosol is not facilitated, when the included angle between the conical inclined plane and the axis of the air outlet channel 11 is controlled within the range of 0-2 degrees, the flow rate of the atomized aerosol before the user inhales can be kept in a stable state, and the settlement and accumulation of condensate on the wall surface of the air outlet channel 11 can be avoided by the stable airflow of the atomized aerosol.
