The embodiments described below and the features of the embodiments can be combined with each other without conflict.

In order to solve the technical problems of poor structural stability and poor liquid leakage prevention effect of the atomization device in the prior art, an embodiment of the invention provides an atomization device. The atomization device comprises an air inlet, an air outlet and an atomization cavity. The atomizing cavity is respectively communicated with the air inlet and the air outlet, the atomizing assembly is arranged in the atomizing cavity, the part of the inner wall of the atomizing cavity, which is close to the atomizing assembly, is provided with a first capillary liquid absorption structure, and the temperature of the wall of the atomizing cavity at the position of the first capillary liquid absorption structure can be reduced along with the heat absorption and atomization of the aerosol matrix after the first capillary liquid absorption structure absorbs the aerosol matrix. As described in detail below.

Referring to fig. 1 and fig. 2, fig. 1 is a schematic structural diagram of an atomizing device according to an embodiment of the present invention, and fig. 2 is a schematic structural sectional diagram of the atomizing device shown in fig. 1 in a direction a-a.

In one embodiment, the aerosolization device 10 may be in the form of, for example, an electronic cigarette. Of course, a medical atomizing apparatus and the like applied to the medical field may be used. The following description is given by way of example, and not limitation, of an aerosolization device 10 in the form of an electronic cigarette.

Specifically, the atomizing device 10 includes an air inlet 11, an air outlet 12, and an atomizing chamber 13. The atomizing chamber 13 is communicated with the air inlet 11 and the air outlet 12, respectively, and an atomizing assembly 14 is disposed in the atomizing chamber 13, wherein the atomizing assembly 14 is used for atomizing aerosol substrate (such as tobacco tar, liquid medicine, etc.) in the atomizing device 10.

The position of the air inlet 11 is the position of air inlet of the atomizing device 10. When the user draws, external air enters the nebulizing chamber 13 from the air inlet 11 to carry the aerosol substrate nebulized by the nebulizing assembly 14 within the nebulizing chamber 13 to the air outlet 12 and out to the user for inhalation by the user.

Alternatively, the atomizing assembly 14 can be a porous heat generator that absorbs the aerosol substrate by capillary force and generates heat to atomize the aerosol substrate. Preferably, the atomizing assembly 14 may be a porous ceramic heat-generating body or the like, which may be further provided with a heat-generating film. Of course, in other embodiments of the present invention, the atomizing assembly 14 may also be a combination of fiber cotton and a heating wire, and is not limited herein.

Considering the stability problems that the cavity wall of the atomization cavity 13 is often deformed and even scorched when the temperature in the atomization cavity 13 is too high, the first capillary liquid absorption structure 15 is disposed on the portion of the inner wall of the atomization cavity 13 close to the atomization assembly 14 in the embodiment. The first capillary wicking structure 15 is used to absorb aerosol substrate that is splashed by frying oil to the walls of the nebulizing chamber 13, aerosol substrate that condenses in the walls of the nebulizing chamber 13, and the like.

Since the aerosol substrate nebulization requires heat absorption and the first capillary wicking structure 15 is at a higher temperature, the aerosol substrate absorbed by the first capillary wicking structure 15 can continue to be nebulized in the first capillary wicking structure 15. In this way, after the first capillary liquid absorption structure 15 absorbs the aerosol substrate, as the aerosol substrate in the first capillary liquid absorption structure 15 continues to be atomized, at least part of heat is absorbed by the aerosol substrate, so that the heat transferred from the atomizing component 14 to the cavity wall of the atomizing cavity 13 at the position of the first capillary liquid absorption structure 15 is reduced, and the heat of the cavity wall of the atomizing cavity 13 at the position of the first capillary liquid absorption structure 15 is absorbed by the aerosol substrate, thereby reducing the temperature of the cavity wall of the atomizing cavity 13 at the position of the first capillary liquid absorption structure 15, that is, reducing the temperature of the cavity wall of the atomizing cavity 13 at the position of the first capillary liquid absorption structure 15 along with the heat absorption and atomization of the aerosol substrate, and thus, stability problems of deformation, scorching and the like of the cavity wall of the atomizing cavity 13 due to overhigh temperature can be avoided, and the structural stability of the atomizing device 10 can be improved.

Of course, the continued atomisation of the aerosol substrate in the first capillary wicking structure 15 also means that the aerosol substrate absorbed by the first capillary wicking structure 15 is reused, which can improve the utilisation of the aerosol substrate of the atomising device 10.

Optionally, in a preferred embodiment, when the atomizing assembly 14 generates heat, the temperature of the cavity wall of the atomizing cavity 13 is less than or equal to 150 ℃. It can be seen that through the design of the first capillary liquid absorption structure 15 of this embodiment, the temperature that can control the wall of the cavity of the atomizing chamber 13 is below 150 ℃, and then effectively avoids the stability problems such as deformation, scorching, etc. of the wall of the atomizing chamber 13 due to the too high temperature.

Further, the first capillary liquid absorption structure 15 of this embodiment is located the part that the atomizing chamber 13 inner wall is close to atomizing component 14, and first capillary liquid absorption structure 15 is close to atomizing component 14 and sets up promptly, can further reduce the risk that the atomizing chamber 13 chamber wall takes place stability problem to further improve atomizing device 10's structural stability.

Also, the first capillary liquid-absorbing structure 15 of the present embodiment has a function of absorbing and storing the aerosol substrate. At least part of the aerosol substrate on the wall of the atomizing chamber 13 can be locked in the first capillary wicking structure 15, so that the aerosol substrate accumulated in the atomizing device 10 can be reduced, the risk of liquid leakage of the atomizing device 10 can be reduced, and the liquid leakage prevention effect of the atomizing device 10 can be improved. For example, for the direct liquid type atomizing device 10, the bottom of the atomizing device 10 tends to accumulate more aerosol substrate, so the first capillary liquid absorption structure 15 of the present embodiment can effectively reduce the aerosol substrate accumulated at the bottom of the atomizing device 10, thereby reducing the risk of liquid leakage of the atomizing device 10 and improving the liquid leakage prevention effect of the atomizing device 10.

It should be noted that when the user just begins to draw, the aerosol matrix in the atomizing assembly 14 is not uniformly distributed and the atomizing assembly 14 is not heated uniformly, i.e., there is a local overheating condition, so that the oil frying phenomenon is most likely to occur. Because atomization component 14 temperature is lower this moment, the aerosol substrate's that splashes because of the frying oil temperature is lower equally, the aerosol substrate that splashes is absorbed by first capillary liquid absorption structure 15 because the temperature is lower can not influence the stable in structure of the atomizing chamber 13 chamber wall at first capillary liquid absorption structure 15 position, can form the protection film in first capillary liquid absorption structure 15 department on the contrary to along with the heat absorption atomizing of aerosol substrate in first capillary liquid absorption structure 15 and reduce the atomizing chamber 13 chamber wall's of first capillary liquid absorption structure 15 position temperature, and then avoid atomizing chamber 13 chamber wall because the high stability problems such as deformation, scorch take place for the temperature.

Referring to fig. 2 to 4, fig. 3 is a schematic structural view of an embodiment of an atomizing assembly, a first carrier and a second carrier of an atomizing device according to the present invention, and fig. 4 is a schematic structural view of the atomizing assembly, the first carrier and the second carrier shown in fig. 3 with an exploded view.

In an embodiment, the atomizing device 10 further includes a first carrier 16 and a second carrier 17, the first carrier 16 and the second carrier 17 are butted to form the atomizing chamber 13, the air inlet 11 is provided on the first carrier 16, the atomizing assembly 14 is provided on the second carrier 17, and the first capillary structure 15 is provided on an inner wall of the second carrier 17. The first capillary-wicking structure 15 may be disposed on a side wall or a bottom wall of the second carrier 17, but is not limited thereto.

Referring to fig. 2 and 5, fig. 5 is a schematic top view of the atomizing assembly, the first carrier and the second carrier shown in fig. 3.

In an embodiment, when the atomizing assembly 14 generates heat to the maximum temperature of 250 ℃, if the wall of the atomizing chamber 13 is not provided with the first capillary liquid absorption structure 15, it is usually required that the distance between the surface of the atomizing assembly 14 and the inner wall of the atomizing chamber 13 reaches more than 2mm to ensure that the wall of the atomizing chamber 13 is not excessively thermally deformed, scorched, etc., so that the area of the cross section of the atomizing chamber 13 is too large to cause too low airflow rate in the atomizing chamber 13 during the suction of the user, which is not favorable for the airflow to carry the atomized aerosol substrate for the user to inhale.

In view of this, the wall of the atomization chamber 13 of the present embodiment, after the first capillary liquid absorption structure 15 is disposed, allows the distance (distance W shown in fig. 5) between the surface of the atomization assembly 14 and the inner wall of the atomization chamber 13 to be reduced to 0.5mm-1.8mm, thereby controlling the temperature of the wall of the atomization chamber 13 to be below 150 ℃. Compared with the case that the first capillary liquid absorption structure 15 is not provided, the distance between the surface of the atomization component 14 and the inner wall of the atomization chamber 13 is reduced, so that the area of the cross section of the atomization chamber 13 is reduced, the airflow speed in the atomization chamber 13 is increased when a user sucks, specifically, the airflow speed in the atomization chamber 13 is increased by at least 10% when the user sucks, and the wall of the atomization chamber 13 can be ensured not to be excessively deformed by heat, scorched and the like. In addition, the reduced distance between the surface of the atomizing assembly 14 and the inner wall of the atomizing chamber 13 in the present embodiment means that the atomizing chamber 13 can be designed with a smaller volume, which is beneficial to the miniaturization of the atomizing device 10.

Preferably, in the case that the wall of the atomization chamber 13 of the present embodiment is provided with the first capillary liquid absorption structure 15, the distance between the surface of the atomization assembly 14 and the inner wall of the atomization chamber 13 is preferably 1mm-1.5mm, so as to increase the airflow velocity in the atomization chamber 13 as much as possible, and simultaneously ensure that the wall of the atomization chamber 13 is not deformed by heat, scorched, etc. as much as possible.

Please continue with fig. 2. In one embodiment, the atomization device 10 also includes an air outlet channel 18. The air outlet channel 18 is respectively communicated with the air outlet 12 and the atomizing cavity 13. The gas entering the nebulizing chamber 13 from the gas inlet 11 carries the aerosol substrate nebulized by the nebulizing assembly 14 to the gas outlet channel 18 and is output to the user along the gas outlet channel 18 for the user to inhale.

Since the atomized aerosol substrate is condensed after contacting the inner wall of the air outlet channel 18, and the aerosol substrate condensed on the inner wall of the air outlet channel 18 returns to the atomizing chamber 13 along the air outlet channel 18, the portion of the inner wall of the atomizing chamber 13 connected to the inner wall of the air outlet channel 18 in this embodiment is provided with the first capillary wicking structure 15 for absorbing the aerosol substrate flowing back along the inner wall of the air outlet channel 18, so as to reuse the aerosol substrate condensed on the inner wall of the air outlet channel 18 and for forming a protective film at the first capillary wicking structure 15 to control the temperature of the chamber wall of the atomizing chamber 13 (i.e. the temperature of the chamber wall of the atomizing chamber 13 at the position of the first capillary wicking structure 15 is reduced along with the endothermic atomization of the aerosol substrate in the first capillary wicking structure 15 as explained in the above embodiment).

Further, in order to guide the aerosol substrate condensed on the inner wall of the air outlet channel 18 to flow back to the atomizing cavity 13, the second capillary liquid absorption structure 181 extending to the atomizing cavity 13 is disposed on the inner wall of the air outlet channel 18 in this embodiment, and after the aerosol substrate condensed on the inner wall of the air outlet channel 18 is absorbed by the second capillary liquid absorption structure 181, the aerosol substrate absorbed by the second capillary liquid absorption structure is guided to the atomizing cavity 13, which is beneficial to optimizing the flow guiding effect of the aerosol substrate on the inner wall of the air outlet channel 18.

Further, a part of the second capillary liquid-absorbing structure 181 communicates with the first capillary liquid-absorbing structure 15 provided at a portion of the inner wall of the atomizing chamber 13 connecting to the inner wall of the air outlet passage 18, and the aerosol matrix in the part of the second capillary liquid-absorbing structure 181 is guided into the first capillary liquid-absorbing structure 15 to contribute to the accumulation of the aerosol matrix in the first capillary liquid-absorbing structure 15, thereby serving to improve the structural stability of the atomizing device 10.

While the remaining part of the second capillary wicking structure 181 is spaced apart from the first capillary wicking structure 15 provided in the portion of the inner wall of the nebulizing chamber 13 connecting to the inner wall of the air outlet channel 18, i.e. the remaining part of the second capillary wicking structure 181 is not in communication with the first capillary wicking structure 15, and the aerosol matrix in this part of the second capillary wicking structure 181 can be directed directly to the nebulizing assembly 14 for re-nebulizing by the nebulizing assembly 14.

Please continue with fig. 2. In one embodiment, the portion of the atomizing chamber 13 communicating with the air outlet channel 18 is provided with a tapered channel 131. The cross-sectional area of the tapered passage 131 gradually decreases in a direction approaching the air outlet passage 18 (as indicated by an arrow X in fig. 2, the same applies hereinafter), and the first capillary-wicking structure 15 provided in the portion of the inner wall of the atomizing chamber 13 connecting the inner wall of the air outlet passage 18 is at least partially located on the inner wall of the tapered passage 131.

When the phenomenon of obvious oil frying occurs, the large-droplet aerosol substrate which is vertically splashed towards the direction close to the air outlet channel 18 returns to the atomizing component 14 under the action of gravity and is heated and atomized again, part of the large-droplet aerosol substrate which is splashed towards the periphery is absorbed by the first capillary liquid absorption structure 15 on the side surface, and the other part of the aerosol substrate is obliquely and upwards splashed towards the direction close to the air outlet channel 18, has vertical and upward component velocity, and can be blocked by the inner wall of the tapered channel 131 and absorbed by the first capillary liquid absorption structure 15 on the inner wall of the tapered channel 131, and the small-droplet aerosol substrate can enter the air outlet channel 18 under the driving of air flow and cannot be influenced by the tapered channel 131. In this way, it is avoided that large droplets of aerosol substrate enter the air outlet channel 18 and are inhaled by the user, which affects the user's taste.

Also, when a user draws, the airflow flows through the tapered channel 131, and since the cross-sectional area of the tapered channel 131 gradually decreases in a direction close to the air outlet channel 18, the flow velocity of the airflow in the tapered channel 131 increases, which is beneficial for the airflow to carry the atomized aerosol substrate out to the user, and also can alleviate the condensation of the atomized aerosol substrate.

Referring to fig. 6, fig. 6 is a schematic structural view of the atomizing device shown in fig. 2 without an atomizing assembly.

The first capillary-liquid absorbing structure 15 may be a capillary groove or the like having a capillary force, and can absorb the aerosol substrate by the capillary force. Of course, the first capillary liquid absorption structure 15 may also be other structures with capillary force, for example, the surface of the atomization cavity 13 is roughened by grinding or the like to form a structure with capillary force in the form of frosted surface, lines or the like, that is, the first capillary liquid absorption structure 15. The first capillary wicking structure 15 will be described below by taking capillary grooves as an example, and the type of the first capillary wicking structure 15 is not limited thereto.

In one embodiment, the first capillary wicking structure 15 includes a first capillary channel 151 and a second capillary channel 152. The first capillary groove 151 is provided in a portion of the inner wall of the atomizing chamber 13 that is connected to the inner wall of the air outlet channel 18, and the second capillary groove 152 is located away from the air outlet channel 18 relative to the first capillary groove 151. Wherein a gap 19 is provided between first capillary channel 151 and second capillary channel 152, and aerosol substrate in first capillary channel 151 enters second capillary channel 152 after confluence of gap 19. In this way, the aerosol substrate in the first capillary grooves 151 is allowed to be uniformly mixed and distributed into the second capillary grooves 152 at the gaps 19, so as to improve the uniformity of the aerosol substrate distribution in the first capillary wicking structure 15 on the inner wall of the nebulizing chamber 13, which is beneficial for reducing the risk of structural stability problems on the wall of the nebulizing chamber 13.

Further, the width of first capillary groove 151 and second capillary groove 152 is preferably less than 1mm so that first capillary groove 151 and second capillary groove 152 have sufficient capillary wicking capability. If the width of first capillary groove 151 and second capillary groove 152 is too large, the capillary wicking capability of first capillary groove 151 and second capillary groove 152 may be reduced and insufficient for use. Also, the design values for both the widths of first capillary channel 151 and second capillary channel 152 are dependent on the viscosity of the aerosol substrate and the structural design constraints of the atomizing device 10. In addition, the larger the depth of the capillary groove is, the larger the liquid storage amount is, so that under the condition that the structure allows, the depth of the capillary groove is increased, the liquid storage amount of the first capillary groove 151 and the second capillary groove 152 is increased, and the risk of liquid leakage is reduced.

Also, each of the first capillary grooves 151 and the second capillary grooves 152 may extend in a direction close to the air outlet passage 18, that is, in a direction close to the air outlet 12, as indicated by an arrow X in fig. 6. Further, the first capillary groove 151 and the second capillary groove 152 are vertical grooves, which facilitates injection molding of the first capillary groove 151 and the second capillary groove 152. Of course, in other embodiments of the present invention, the first and second capillary grooves 151 and 152 may also be other than vertical grooves, for example, by 3D printing techniques or the like.

In summary, in the atomization device provided by the present invention, the first capillary liquid absorption structure is disposed on a portion of the inner wall of the atomization chamber, which is close to the atomization assembly. The first capillary liquid absorption structure is used for absorbing the aerosol substrate and can reduce the temperature of the wall of the atomization cavity at the position of the first capillary liquid absorption structure along with the heat absorption atomization of the aerosol substrate after the aerosol substrate is absorbed, so that the stability problems of deformation, scorching and the like of the wall of the atomization cavity due to overhigh temperature are avoided, and the structural stability of the atomization device can be improved.

In addition, in the present invention, unless otherwise expressly specified or limited, the terms "connected," "stacked," and the like are to be construed broadly, e.g., as meaning permanently connected, detachably connected, or integrally formed; either directly or indirectly through intervening media, either internally or in any other relationship.
