Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

In the embodiment of the present application, a plurality refers to not less than two.

Referring to fig. 1, 3 and 5, an atomizer 1000 includes an atomizing base 100, an atomizing core 4 and a housing 200.

The nebulizer 1000 is used to nebulize an aerosol-generating substrate to produce an aerosol for inhalation by a user.

Aerosol-generating substrates include, but are not limited to, pharmaceutical products, nicotine-containing materials, or nicotine-free materials, and the like.

The housing 200 has a cavity and an outlet channel 201a (see fig. 3 and 5), the nebulization cartridge 100 being at least partially disposed in the cavity, the top wall of the nebulization cartridge 100 and the side walls of the cavity together defining a reservoir 200a for storing an aerosol-generating substrate. The outlet channel 201a communicates with the external environment.

Referring to fig. 7, the atomizing base 100 includes an atomizing top base 1 and an atomizing base 2.

Referring to fig. 4 and 6, the atomizing base 2 is disposed at the bottom side of the atomizing top base 1, and defines an atomizing chamber 100a together with the atomizing top base 1.

The atomization footstock 1 is provided with a liquid inlet channel 1a (refer to figure 6) and an air guide space,

the atomizing core 4 is disposed in the atomizing chamber 100a, specifically, at the extending end of the liquid inlet channel 1a, and the liquid inlet channel 1a is used for guiding the aerosol-generating substrate in the liquid storage chamber 200a to the atomizing core 4. The atomizing core 4 is used for absorbing and heating the atomized aerosol generating substrate, and the aerosol generated by heating the atomizing core 4 is discharged through the air outlet channel 201a for being sucked by a user.

Referring to fig. 8 to 11, the atomizing base 100 further includes a guiding element 3, the guiding element 3 is disposed in a space enclosed by the atomizing top base 1 and the atomizing base 2, specifically, a bottom end of the guiding element 3 is located in the atomizing cavity 100a, and a top end of the guiding element 3 extends into the air guiding space and defines an air guiding channel 100b together with a part of side walls of the air guiding space.

The air guide channel 100b communicates with the nebulization chamber 100a for guiding out aerosol in the nebulization chamber 100a. Specifically, the air guide channel 100b communicates with the atomizing chamber 100a and the air outlet channel 201a, and the aerosol in the atomizing chamber 100a sequentially flows through the air guide channel 100b and the air outlet channel 201a, and is discharged from the end of the air outlet channel 201a to be inhaled by the user.

During inhalation, the air outlet channel 201a generates negative pressure, aerosol in the air guide channel 100b and the atomization cavity 100a is inhaled into the air outlet channel 201a under the action of the negative pressure, and then enters the oral cavity of a user, the atomization cavity 100a generates negative pressure, and air in the external environment is supplemented into the atomization cavity 100a under the action of the negative pressure, so that continuous aerosol inhalation is realized.

It should be noted that, in the related art, the inner wall of the atomization footstock 1 may form some protruding structures and corner portions based on structural requirements, and the protruding structures and corner portions easily cause the aerosol to generate vortex in the flowing process, so that more condensate is generated, on one hand, the smoke amount is reduced, on the other hand, more condensate is easily sucked into the oral cavity of the user, and the user experience is affected.

According to the atomization seat disclosed by the embodiment of the application, the flow guide piece 3 can play a role in guiding flow, at least plays a role in regulating the wall surface of the air guide channel to a certain extent, is beneficial to guiding aerosol flow, reduces the generation of condensate and improves the user experience; in addition, the structural limitation on the inner wall of the atomization footstock 1 can be reduced, and the technological requirement on the side wall of the atomization footstock 1 can be reduced.

Illustratively, the atomization footstock 1 is an integrally formed plastic part, so that the number of parts of the atomization footstock 1 can be reduced, and the assembly time can be reduced.

For example, referring to fig. 7 and 12, a side wall of the air guiding space is provided with a die outlet 11c penetrating through the side wall, and the air guiding member 3 shields the die outlet 11c. The die opening 11c is a hole formed to satisfy the requirement of the injection molding process.

In this embodiment, the deflector 3 shields the die opening 11c, improves the tightness of the air guide channel 100b, reduces the amount of dispersion of aerosol from the die opening 11c to the circumferential outside of the atomizing top base 1, and is advantageous in providing the amount of smoke of the atomizer 1000.

For example, referring to fig. 9, the top wall of the atomizing base 2 is provided with an air inlet 21b and a mounting opening 21c for penetrating the conductive member, and external fresh air enters the atomizing chamber 100a from the bottom side of the atomizing base 2 through the air inlet 21 b. The specific connection mode of the atomizing base 2 and the atomizing top seat 1 is not limited.

For example, referring to fig. 8 to 11, connecting lugs 22 are formed on opposite sides of the top of the atomizing base 2, and the connecting lugs 22 extend into the atomizing chamber 100a and are connected to the atomizing top base 1.

In some embodiments, referring to fig. 8 to 11, a clamping groove 22b is disposed on a side of the two connecting lugs 22 facing away from each other, and referring to fig. 6, a clamping hook 111 is disposed on an inner wall of the atomizing base 2, and the clamping groove 22b is in clamping fit with the clamping hook 111.

Specifically, when the two connection lug plates 22 are inserted into the atomization footstock 1, the two connection lug plates 22 are pressed by the clamping hooks 111, and are elastically deformed in the direction of being close to each other until the clamping grooves 22b are aligned to the clamping hooks 111, the clamping hooks 111 are hooked into the clamping grooves 22b, the connection lug plates 22 recover to deform, and the clamping hooks 111 are restrained in the clamping grooves 22b, so that the quick connection between the atomization footstock 1 and the atomization footstock 2 is realized.

In some embodiments, the number of the guide members 3 is two, the two connecting lugs 22 and the two guide members 3 are alternately arranged along the circumferential direction of the top of the atomizing base 2, and the adjacent connecting lugs 22 and the guide members 3 are arranged at a central angle of approximately 90 degrees, so that interference between the guide members 3 and the connecting lugs 22 is prevented, and the layout is compact and reasonable.

The connection mode of the flow guiding piece 3 and the atomizing base 2 is not limited.

For example, referring to fig. 9 and 10, in some embodiments, the deflector 3 and the atomizing base 2 are integrally formed, such as integrally injection molded.

In other embodiments, referring to fig. 11, the flow guiding member 3 is connected to the atomizing base 2 as a separate component, for example, by welding, clamping, riveting, etc., which is not limited herein. Specifically, in the embodiment in which the number of the flow guiding members 3 is two, the connecting plate 31 is arranged between the two flow guiding members 3, the connecting plate 31 and the two flow guiding members 31 are formed into a whole structure, and the whole structure is connected with the atomizing base 2, so that the connection reliability of the flow guiding members 3 and the atomizing base 2 can be improved.

Referring to fig. 9, 10 and 11, for example, the top of the atomizing base 2 is provided with a liquid collecting area 21a for collecting condensate generated by condensation of aerosol. It should be noted that, part of condensate is inevitably generated during the flow of aerosol, and condensate is also generated by aerosol remaining in the aerosol generating device after the user stops sucking, at least part of condensate is collected in the liquid collecting area 21a, so as to reduce the probability of condensate leakage.

The portion around the air inlet 21b and the mounting port 21c is higher than the bottom surface of the liquid collecting region 21a, so that condensate in the liquid collecting region 21a is prevented from flowing into the air inlet 21b and the mounting port 21c in the backward direction.

The specific manner of forming the liquid collecting region 21a is not limited. For example, referring to fig. 9 and 10, the edge of the top wall of the atomizing base 2 is provided with a skirt 21, the skirt 21 extends continuously along the edge of the top wall of the atomizing base 2, and the skirt 21 and the top wall of the atomizing base 2 enclose a liquid collecting region 21a.

Referring to fig. 4 and 6, for example, the atomizing base 100 includes a liquid absorbing pad 5, and the liquid absorbing pad 5 is disposed in the liquid collecting area 21a for absorbing condensate in the liquid collecting area 21a. The liquid-absorbing cotton 5 has liquid-absorbing capability, and when the amount of condensate flowing into the liquid-collecting area 21a is smaller than the liquid-absorbing amount of the liquid-absorbing cotton 5, free-flowing condensate can not be generated in the liquid-collecting area 21a, so that the liquid leakage probability is further reduced.

The liquid absorbent cotton 5 may be woven from fine fibers having a lipophilic property, for example, fibers produced by melt-blowing inert polypropylene and nonwoven fabrics.

For example, referring to fig. 9 and 10, the surface of the flow guiding member 3 for guiding the airflow is provided with a first liquid guiding groove 3a, and the first liquid guiding groove 3a is used for guiding the condensate formed by aerosol to the liquid collecting region 21a, that is, the condensate flows down in the first liquid guiding groove 3a until flowing to the liquid collecting region 21a. The first liquid guiding groove 3a extends substantially along the height direction of the guide member 3, and may extend straight from the top end to the bottom end of the guide member 3, or may extend in a curved line, without limitation, as long as the condensate can be facilitated to flow down in the first liquid guiding groove 3 a.

The first liquid guide groove 3a is convenient for guiding condensate to the liquid collecting area 21a in time, so that the condensate is not easy to gather on the surface of the guide piece 3, and in addition, the large liquid drops wrapped in aerosol are also convenient to adsorb, the aerosol is kept dry, and the probability of sucking and leaking liquid is reduced.

The number of the first liquid guiding grooves 3a is not limited, and may be one or a plurality.

For example, referring to fig. 4, a second liquid guiding groove 11d is disposed on an inner wall of the atomization footstock 1 facing the atomization cavity 100a, and the second liquid guiding groove 11d is used for guiding the condensate formed by aerosol to the liquid collecting region 21a, that is, the condensate flows down in the second liquid guiding groove 11d until flowing to the liquid collecting region 21a. The second liquid guide groove 11d extends substantially in the height direction of the inner wall of the atomizing top base 1, and may extend straight or may extend in a curved line, and is not limited thereto, as long as the condensate can be easily caused to flow down in the second liquid guide groove 11d.

The second liquid guide groove 11d is convenient for guiding condensate to the liquid collecting area 21a in time, so that condensate is not easy to gather on the side wall around the atomization cavity 100a, and in addition, large liquid drops wrapped in aerosol are convenient to adsorb, the aerosol is kept dry, and the probability of sucking and leaking liquid is reduced.

It should be noted that, in the inner wall of the atomization footstock 1 facing the atomization chamber 100a, one inner wall may be provided with one or more second liquid guiding grooves 11d, or one or more second liquid guiding grooves 11d may be respectively provided on the inner walls.

As an example, referring to fig. 9, 10 and 11, a third liquid guiding groove 22a is formed on a surface of the connection lug 22 facing the atomizing chamber 100a, and the third liquid guiding groove 22a is used for guiding condensate formed by aerosol to the liquid collecting region 21a, that is, the condensate flows down in the third liquid guiding groove 22a until flowing to the liquid collecting region 21a. The third liquid guide groove 22a extends substantially in the height direction of the connection lug plate 22, and may be straight or curved, as long as the condensate can flow down in the third liquid guide groove 22a without limitation.

The third liquid guide groove 22a is convenient for guiding condensate to the liquid collecting area 21a in time, so that condensate is not easy to gather on the surface of the connecting lug plate 22, and in addition, large liquid drops wrapped in aerosol are also convenient to adsorb, keep the aerosol dry and cool, and reduce the probability of sucking and leaking.

The number of the third liquid guiding grooves 22a on the single connection lug plate 22 may be one or a plurality, and is not limited herein.

For example, referring to fig. 6, 7 and 12, the outer surface of the atomization footstock 1 in the circumferential direction is provided with an external liquid storage groove 112a, and the inner wall of the atomization footstock 1 facing the air guide channel 100b is provided with a lateral liquid guide groove 11f. The lateral liquid guiding groove 11f passes through the die outlet 11c and extends to the circumferential outer surface of the atomizing top base 1, and communicates with the external liquid storing groove 112a. Part of condensate generated in the air guide passage 100b adheres to the inner wall of the air guide passage 100b, and part enters the lateral liquid guide groove 11f and flows into the external liquid reservoir 112a along the lateral liquid guide groove 11f. The external liquid storage tank 112a plays a role of distributing a part of condensate, reasonably dispersing the storage of condensate, reducing the accumulation pressure of the liquid collecting area 21a and reducing the probability of pumping leakage.

The lateral liquid guiding groove 11f is located higher than the second liquid guiding groove 11d.

The specific configuration of the external reservoir 112a is not limited.

As an example, referring to fig. 7 and 12, a plurality of ribs 112 are formed on the circumferential outer surface of the atomizing top seat 1, and the ribs 112 extend along the circumferential direction of the atomizing top seat 1, it is understood that the same rib 112 may continuously encircle the circumferential surface of the atomizing top seat 1 for one circle, or may be disposed along the circumferential direction in a broken manner, which is not limited herein.

The ribs 112 are arranged at intervals in the direction of the height direction of the atomizing top base 1, and the interval between two adjacent ribs 112 forms an external reservoir 112a. This can form a large number of external reservoirs 112a, thereby increasing the capacity.

For example, referring to fig. 4, 6 and 12 in combination, the atomizing top 1 includes a housing portion 11 and a partition housing portion 12, the partition housing portion 12 being disposed inside the housing portion 11.

The outer contour of the housing portion 11 determines the outer contour of the atomizing top 1. The top wall of the housing part 11 is provided with an air guide port 11a and a liquid inlet port 11b.

The air guide opening 11a is located at the center of the top wall of the housing part 11. Referring to fig. 3 and 5, an air outlet pipe 201 is provided in the housing 200, a space in the air outlet pipe 201 is an air outlet channel 201a, and a bottom end of the air outlet pipe 201 is inserted into the air guiding port 11a.

Illustratively, the air guide 11a is located directly above the partition shell portion 12.

Referring to fig. 4, the partition shell portion 12 has a liquid guiding space 12a therein, and the liquid guiding space 12a is open at a bottom side and closed at a top side. The liquid guiding space 12a communicates with the liquid inlet 11b to form a liquid inlet channel 1a, i.e. the aerosol-generating substrate in the liquid storage chamber 200a flows into the liquid guiding space 12a of the divided housing part 12 via the liquid inlet 11b.

The atomizing core 4 is arranged at the opening of the liquid guiding space 12a, and the atomizing core 4 blocks the flow of the aerosol-generating substrate in the liquid inlet channel 1a, that is, the aerosol-generating substrate does not flow directly into the atomizing chamber 100a.

The number of the liquid inlet passages 1a is not limited, and may be one or a plurality of. Illustratively, the number of the liquid inlet passages 1a is plural. In this way, the arrangement of the liquid inlet channels 1a is not only convenient for the aerosol generating substrate in the liquid storage cavity 200a to be conveyed to the atomization core 4 through the liquid inlet channels 1a for heating and atomization, so that the atomization efficiency is improved, but also the problem that the liquid absorption of the atomization core 4 is blocked due to the blockage of any liquid inlet channel 1a, so that the atomization core 4 is dry-burned can be avoided.

In a specific embodiment, the number of the liquid inlet channels 1a is two, that is, the number of the liquid inlets 11b is also two, the two liquid inlets 11b are located at two opposite sides of the air guiding port 11a, and the three are substantially linearly arranged along the first direction. The partition casing portion 12 extends substantially in the first direction, and both ends thereof are communicated to the liquid inlet 11b through the process flow passage of the seat casing portion 11.

Two air guide spaces are defined between the outer surfaces of the opposite sides of the partition casing portion 12 and the inner wall of the seat casing portion 11, and both the air guide spaces are communicated with the same air guide port 11a. Specifically, the two air guiding spaces are located at opposite sides of the partition shell portion 12 in a second direction, wherein the second direction is perpendicular to the first direction and perpendicular to the height direction.

The arc-shaped flow guide surface 3b can guide aerosol to flow along the arc-shaped flow guide surface 3b to the upper air guide opening 11a, so that vortex generation is reduced, and condensate formation is reduced.

In other embodiments, referring to fig. 10, the guide member 3 may be substantially flat and plate-shaped, and the above-mentioned arc-shaped guide surface may not be provided.

Illustratively, flow guides 3 are provided in the air guiding space on opposite sides of the dividing shell portion 12.

The two flow guiding members 3 are symmetrically arranged at opposite sides of the partition shell portion 12. Thus, the two air guide passages 100b are made to have substantially the same mist-discharging performance.

The particular type of atomizing core 4 is not limited, and in some embodiments, atomizing core 4 is in the form of a resistive wire.

In other embodiments, the atomizing core 4 is a ceramic atomizing core.

The top surface of the guide portion 61 has an arc-shaped guide surface 61a, and the atomizing core 4 is located on the concave side of the arc-shaped guide surface 61a, i.e., the arc-shaped guide surface 61a is recessed substantially toward the bottom side. The curved guide surface 61a serves to guide a part of the air flow from the air inlet 21b to the surface of the deflector 3.

Referring to fig. 4 and 8, the thickness of the guide portion 61 near the air inlet 21b is smaller than that near the air guide member 3, so that the height of the arc-shaped guide surface 61a near the air inlet 21b is smaller than that near the air guide member 3, which is convenient for the air flow to flow along the arc-shaped guide surface 61a towards the air guide channel 100b, reducing the vortex and reducing the formation of condensate.
