[0002] In the related technology, the resistive heating atomization structure mostly uses a columnar heating element. The common columnar heating element usually adopts a combination of a nautilus heating wire and a porous substrate. The traditional nautilus heating wire is embedded in the inner surface of the porous circular substrate to form a heating element. The nautilus heating wire and the inner surface of the porous circular substrate constitute an atomization airway. However, the liquid conduction path and difficulty of the atomized liquid in the porous substrate are relatively large, which makes it impossible for the atomized liquid in the porous body to be transmitted to the location of the heating element in time, and it is easy to cause problems such as dry burning and burnt smell.

[0045] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0046] The core of the present invention is to provide an atomization assembly, which can reduce the liquid conduction path and difficulty of the atomized liquid, so that the atomized liquid has a good circulation effect, prevents the atomized liquid from being dry-burned, effectively improves the use effect of the atomization assembly and prolongs the service life. Another core of the present invention is to provide an electronic atomization device including the above-mentioned atomization assembly.

[0047] like Figure 1 and Figure 2As shown, an embodiment of the present application provides an electronic atomization device, which includes a shell 4, a ventilation pipe 5 and an atomization component, wherein the ventilation pipe 5 is arranged in the shell 4, and a liquid storage chamber 6 is defined between the outer wall of the ventilation pipe 5 and the inner wall of the shell 4, and the liquid storage chamber 6 is used to store atomization media such as smoke liquid and medicine liquid. The inner wall of the ventilation pipe 5 defines an air flow channel, and the atomization component is arranged in the air flow channel of the ventilation pipe 5 and is connected with the atomized liquid in the liquid storage chamber 6. The atomized liquid in the liquid storage chamber 6 is absorbed by the atomization component and atomized in the atomization channel 21 of the atomization component to form an aerosol. When the user inhales, the aerosol formed by atomization is mixed with air in the air flow channel and is inhaled by the user along with the inhalation airflow.

[0048] In some embodiments, Figure 3 As shown, the atomization assembly includes a heating element 1 and a first porous body 2. The heating element 1 refers to a structure having a heating portion 11; the heating element 1 having the heating portion 11 is arranged on the first porous body 2. The first porous body 2 is provided with at least two atomization channels 21 spaced apart in the circumferential direction and extending to both ends of the axial direction on the outer wall, and each atomization channel 21 is provided with a heating portion 11 on the side wall in the radial direction, and the first porous body 2 is also provided with a liquid storage and diversion structure 22 corresponding to the heating portion 11 and extending at least partially in the axial direction.

[0049] It should be noted that the first porous body 2 can be a columnar, barrel-shaped or long and narrow structure, that is, the first porous body 2 should have an axial direction and a circumferential direction, the first porous body 2 has at least an outer wall, the outer wall has two atomization channels 21, which are arranged in sequence and spaced apart in the circumferential direction of the outer wall, and the atomization channel 21 is arranged through the first porous body 2 in the axial direction, the atomization channel 21 is a concave structure on the surface of the first porous body 2, and the side wall of the concave structure is provided with the above-mentioned heating part 11, and the setting of the heating part 11 can be in various forms, wherein the heating part 11 is used to heat and atomize the atomized liquid on the first porous body 2 to form an aerosol, and the formed aerosol flows in the atomization channel 21 to the air outlet of the air flow channel to be inhaled by the user.

[0050] The first porous body 2 is also provided with a liquid storage and flow guiding structure 22, and the liquid storage and flow guiding structure 22 has a portion extending along the axial direction of the first porous body 2, so that the flow guiding direction at least partially extends along the axial direction. The position of the liquid storage and flow guiding structure 22 corresponds to the position of the heating part 11, and it can be understood that the two are opposite, or because the corresponding positions are set, the effects present corresponding effects.

[0051] In view of the above-mentioned scheme, when using the above-mentioned atomization assembly, since the first porous body 2 is provided with at least two atomization channels 21 spaced circumferentially and extending to both ends of the axial direction, a heating portion 11 is provided on the side wall of each atomization channel 21 in the radial direction, that is, the device includes at least two heating portions 11, which helps to increase the amount of atomization. In addition, the heating portion 11 is concentrated on the outer side wall of the first porous body 2, so that the atomization surface atomized by heat is exposed, which is convenient for detecting the structure and performance parameters of the heating element, and can improve the quality control effect of the device. For example, the heating portion 11 is directly embedded in the outer surface of the atomization channel 21 (that is, the side of the atomization channel 21 facing the atomization channel 21 facing the side wall opening of the first porous body 2), so that the heating portion 11 and the first porous body 2 are not deformed during molding and processing, and the performance consistency of the heating portion 11 is ensured.

[0052] The heating portion 11 at least has a portion extending in the axial direction, so that the liquid circulation must move in the axial direction, thereby simplifying the flow path of the atomized liquid and reducing the difficulty of guiding the liquid.

[0053] Moreover, a liquid storage and guide structure 22 is provided in the first porous body 2, which corresponds to the heating part 11 and extends at least partially in the axial direction. Through the action of the liquid storage and guide structure 22, the liquid guide path and difficulty of the atomized liquid in the first porous body 2 can be reduced, thereby avoiding the problem of dry burning smell caused by the atomized liquid in the first porous body 2 not being able to be transmitted to the location of the heating part 11 in time.

[0054] In summary, the atomization component provided by the present invention can reduce the liquid guide path and difficulty of the atomized liquid, so that the atomized liquid can circulate well and prevent the atomized liquid from drying out, thereby effectively improving the use effect of the atomization component and extending its service life. In addition, the atomization surface of the device is exposed, which is convenient for detecting the structure and performance parameters of the heating element, thereby improving the quality control effect of the device.

[0055] Based on the above embodiments, the present application provides a specific solution, combining Figures 1 to 3 As shown, the first porous body 2 includes an atomization part 23 and at least two liquid absorption parts 24 arranged circumferentially at intervals on the side wall of the atomization part 23, and the intervals between adjacent liquid absorption parts 24 define an atomization channel 21, and the heating part 11 is arranged on the side of the atomization part 23 facing the atomization channel 21; at least one of the atomization part 23 and the liquid absorption part 24 is provided with a liquid storage and diversion structure 22.

[0056] Please refer to Figures 3 to 5, wherein the first porous body 2 includes an atomizing part 23 as a main structure and a liquid absorbing part 24 arranged on the side of the atomizing part 23, the liquid absorbing part 24 is arranged protruding relative to the atomizing part 23, and the side of the liquid absorbing part 24 away from the atomizing part 23 is a liquid absorbing surface, and a lower oil port (not shown) connecting the air flow channel and the liquid storage chamber 6 is provided on the side wall of the vent pipe 5, so that the atomized liquid in the liquid storage chamber 6 flows to the liquid absorbing surface of the liquid absorbing part 24 through the lower oil port to be absorbed by the liquid absorbing part 24. A recessed structure is formed between two adjacent liquid absorbing parts 24 in the circumferential direction of the first porous body 2, namely, the atomizing channel 21, that is, compared with the liquid absorbing part 24, the atomizing channel 21 is a recessed structure.

[0057] The liquid storage and flow guiding structure 22 can be arranged in the atomization part 23 or in the liquid absorption part 24 , or the atomization part 23 has the liquid storage and flow guiding structure 22 , and the liquid absorption part 24 has the liquid storage and flow guiding structure 22 .

[0058] Furthermore, combined with Figure 1 and Figure 2 As shown, the outer wall of the first porous body 2 for contacting the inner wall of the vent pipe 5 is wrapped with a third porous body 7, wherein the third porous body 7 can be a flexible porous body, such as porous cotton, etc. Specifically, the third porous body 7 is coated on the outer surface of the liquid absorption part 24, that is, the liquid absorption surface of the liquid absorption part 24.

[0059] Based on the above embodiment, the first porous body 2 is provided with liquid absorption parts 24 on two opposite sides in a first radial direction, and the first porous body 2 is provided with atomization channels 21 on two opposite sides in a second radial direction, and the first radial direction is perpendicular to the second radial direction.

[0060] Among them, there are two liquid suction parts 24 and atomization channels 21, and the two are arranged in pairs, so that the liquid suction parts 24 and the atomization channels 21 are arranged alternately in the circumferential direction. In order to rationalize the space of the two and make the effects of the liquid suction parts 24 and the atomization channels 21 better, the two liquid suction parts 24 are arranged along the first radial direction and symmetrically about the axis of the first porous body 2. Similarly, the two atomization channels 21 are arranged along the second radial direction and symmetrically about the axis of the first porous body 2. The first radial direction is perpendicular to the second radial direction, so that a single liquid suction part 24 or a single atomization channel 21 occupies at most one-quarter of the circumference of the first porous body 2, and adjacent ones do not overlap in the circumferential direction.

[0061] Optionally, the above arrangement can also be extended to a situation where there are multiple groups of liquid suction parts 24 and atomization channels 21 , and it is only necessary to ensure that the liquid suction parts 24 and atomization channels 21 can be alternately arranged in the circumferential direction.

[0062] In some embodiments, continue to refer to Figures 3 to 5When the number of the liquid storage and guide structures 22 is 1, the liquid storage and guide structure 22 is located at the geometric center of the top of the first porous body 4; when the number of the liquid storage and guide structures 22 is greater than 1, the multiple liquid storage and guide structures 22 are symmetrically distributed or circumferentially arrayed or linearly arrayed, and of course they can also be irregularly arranged.

[0063] In some specific embodiments, Figure 3 and Figure 4 As shown, the liquid storage and flow guiding structure 22 is arranged in the middle of the atomizing part 23 and / or the liquid absorbing part 24, that is, only one of the atomizing part 23 and the liquid absorbing part 24 is provided with the liquid storage and flow guiding structure 22 in the middle, or both are provided with the liquid storage and flow guiding structure 22 in the middle. Figure 5 As shown, there may be multiple liquid storage and guide structures 22, and the multiple liquid storage and guide structures 22 are arranged at intervals along the first radial direction, and a part of the multiple liquid storage and guide structures 22 is arranged in the liquid absorption part 24, and the other part is arranged in the atomization part 23, wherein the multiple liquid storage and guide structures 22 all have an extension along the axial direction of the first porous body 2.

[0064] In some embodiments, Figure 6 As shown, there may be one liquid storage and flow guiding structure 22 , and the liquid storage and flow guiding structure 22 extends from the atomization portion 23 to the liquid absorption portion 24 .

[0065] It should be noted that the above-mentioned different types of liquid storage and diversion structures 22 are mainly used for the types of first porous bodies 2 in various situations, and can perform differentiated and targeted adjustments for different types of first porous bodies 2 .

[0066] On the basis of any one of the above embodiments, the liquid storage and flow guiding structure 22 extends to one end where the gas outlet of the first porous body 2 and the atomization channel 21 are located.

[0067] Since the atomized liquid on the first porous body 2 usually flows from top to bottom under the action of gravity, if the liquid storage and diversion structure 22 penetrates to the bottom, it is easy to cause leakage under the action of gravity. Therefore, the present application extends the penetration effect of the liquid storage and diversion structure 22 only to the top, that is, Figure 7 The upward position in the middle is the top, which can reduce the occurrence of leakage. At the same time, the connecting structure of the liquid storage and liquid guiding structure 22 can be adjusted so that the atomized liquid can be transmitted to different positions of the atomization part 23 under the action of the liquid storage and liquid guiding structure 22 to prevent problems such as dry burning.

[0068] Optionally, the liquid storage and flow guiding structure 22 may also extend toward a side where the liquid suction portion 24 is provided. Alternatively, the liquid storage and flow guiding structure 22 may also extend toward a position between where the liquid suction portion 24 is provided and where the atomization channel 21 is provided.

[0069] In some specific embodiments, Figure 7 As shown, the liquid storage and flow guiding structure 22 is a capillary microgroove 25. The capillary microgroove 25 is provided with a capillary microgroove 25, which realizes a channel different from the conventional sense through the particularity of its own structure. The purpose of using the capillary microgroove 25 is to store and guide liquid through the capillary microgroove 25, and at the same time, the capillary action of the capillary microgroove 25 prevents the atomized liquid from leaking out of the capillary microgroove 25.

[0070] Optionally, in the case of using the capillary microgrooves 25, the width of the capillary microgrooves 25 gradually decreases in the axial direction from the air inlet to the air outlet of the atomization channel 21. According to the characteristics of the capillary action, the above-mentioned setting method makes the capillary force of the relevant structure near the corresponding air outlet greater than the capillary force near the air inlet, so that the atomized liquid can resist the gravity in the atomization channel 21 to do work, so that the atomized liquid can overcome the effect of gravity, avoid the atomization operation from transferring the atomized liquid to the upper half of the first porous body 2, and avoid the problem of dry burning due to insufficient liquid supply in the upper half.

[0071] In other embodiments, please combine Figures 3 to 7 As shown, the liquid storage guide structure 22 can also be a non-capillary liquid storage channel 26. Fig. 9 As shown, considering that the use of the non-capillary liquid storage channel 26 may lead to the risk of liquid leakage, a second porous body 3 is arranged in the non-capillary liquid storage channel 26, thereby solving the risk of liquid leakage.

[0072] On the basis of the above embodiment, in order to reduce the risk of liquid leakage, a second porous body 3 is provided in the non-capillary liquid storage channel 26, and the porosity of the second porous body 3 is at least twice the porosity of the first porous body 2. Among them, setting the porosity of the second porous body 3 to be twice or more than the porosity of the first porous body 2 can increase the liquid storage capacity.

[0073] Optionally, in the case of using a non-capillary liquid storage channel 26, the porosity of the second porous body 3 filled in the non-capillary liquid storage channel 26 gradually decreases in the axial direction from the air inlet to the air outlet of the atomization channel. According to the characteristics of capillary action, the above-mentioned setting method makes the capillary force of the relevant structure near the corresponding air outlet greater than the capillary force near the air inlet, so that the atomized liquid can resist gravity in the atomization channel 21. Do work, so that the atomized liquid can overcome the effect of gravity, avoid the atomization operation from transferring the atomized liquid to the upper half of the first porous body 2, and avoid the problem of dry burning due to insufficient liquid supply in the upper half.

[0074] For the first porous body 2, the second porous body 3 and the third porous body 7, the first porous body 2 is porous ceramic, and the second porous body 3 and the third porous body 7 are both porous cotton. Of course, in other embodiments, the first porous body 2 and the second porous body 3 can also be porous ceramics.

[0075] In some embodiments, Figure 7 and Figure 8 As shown, the liquid storage and flow guiding structure 22 includes a non-capillary liquid storage channel 26 and a capillary microgroove 25 .

[0076] Specifically, at least one liquid absorption portion 24 is provided with a non-capillary liquid storage channel 26, and in the first radial direction or the second radial direction, one end of the capillary microgroove 25 is connected to the non-capillary liquid storage channel 26, and the other end of the capillary microgroove 25 extends along the direction corresponding to the atomization portion 23 and the heating portion 11.

[0077] The atomization part 23 has a non-capillary liquid storage channel 26, which is located in the middle of the atomization part 23. The non-capillary liquid storage channel 26 has at least two capillary microgrooves 25 in the circumferential direction, preferably 4 capillary microgrooves 25 or more capillary microgrooves 25. The two liquid absorption parts 24 both have non-capillary liquid storage channels 26. The non-capillary liquid storage channel 26 is provided with the liquid storage guide structure 22 in the middle of the atomization part 23 on the straight line connecting the two non-capillary liquid storage channels 26, that is, in the direction of a diameter.

[0078] By setting the non-capillary liquid storage channel 26 on the liquid absorption part 24, the liquid storage capacity is increased, and the atomized liquid in the non-capillary liquid storage channel 26 is transferred to the atomization part 23 by the capillary action of the capillary microgrooves 25, thereby taking into account the smoothness of the infusion and reducing the overall risk of leakage.

[0079] The number of the non-capillary liquid storage channels 26 and the capillary microgrooves 25 can be adjusted according to actual conditions, and adjacent non-capillary liquid storage channels 26 are connected through the capillary microgrooves 25 or are independent and disconnected. Preferably, adjacent non-capillary liquid storage channels 26 are connected through the capillary microgrooves 25 to achieve faster liquid supply.

[0080] Optionally, the capillary microgroove 25 may also be disposed at a position other than the straight line connecting the two non-capillary liquid storage channels 26 , but needs to be disposed at a position between the two non-capillary liquid storage channels 26 .

[0081] On the basis of the above-mentioned embodiment, each liquid absorbing part 24 is provided with a non-capillary liquid storage channel 26 , and the capillary microgrooves 25 are respectively connected with the non-capillary liquid storage channels 26 on each liquid absorbing part 24 .

[0082] like Figures 10 to 15As shown, for the above-mentioned non-capillary liquid storage channel 26, the non-capillary liquid storage channel 26 is a blind hole, and the cross-sectional shape of the non-capillary liquid storage channel 26 includes but is not limited to polygons such as triangles, rectangles, pentagons, or circles, semicircles, and ellipses, and can be regular shapes or irregular shapes. Among them, the non-capillary liquid storage channel 26 is preferably set to a polygon or a circle to achieve faster liquid supply.

[0083] It should be noted that, in the case where there are multiple non-capillary liquid storage channels 26 , the cross-sectional shapes of the various non-capillary liquid storage channels 26 may be the same or different.

[0084] In some alternative embodiments, the non-capillary liquid storage channel 26 may also be provided as a through hole that circumferentially penetrates to both ends of the first porous body 2 .

[0085] Combination Figure 1 , Figure 2 , Figure 7 as well as Figure 8 As shown, based on any one of the above embodiments, an inclined surface 27 is provided on a side wall of the atomization channel 21 along the radial direction close to the air outlet, so that the air outlet is in a flared shape.

[0086] It should be noted that the angle of the inclined surface 27 of the side wall along the radial direction close to the air outlet is not unique and can be adjusted within a certain range to improve the uniformity of the flow field when the aerosol flows to the air outlet, making the temperature field relatively more uniform, avoiding local high temperatures, reducing collisions of aerosol particles, and thus forming a more delicate effect.

[0087] Optionally, the axial inclination angle between the inclined surface 27 and the atomization channel 21 ranges from 0° to 60°.

[0088] The end of each atomizing channel 21 is provided with an inclined surface 27 for guiding flow, and the guiding angle of the inclined surface 27 is 0-60°. The transition between the atomizing channel 21 and the inclined surface 27 maintains a sharp feature, and the guiding angle of the inclined surface 27 can be determined according to the actual situation and actual needs during actual use.

[0089] On the basis of the above embodiments, preferably, the first porous body 2 is a columnar structure, and the cross-section of the first porous body 2 includes a first fan-shaped surface, a second fan-shaped surface symmetrically distributed with the first fan-shaped surface, and a rectangular surface, the rectangular surface is used to connect the first fan-shaped surface and the second fan-shaped surface, the arc edges of the first fan-shaped surface and the second fan-shaped surface are both arranged close to the inner wall surface of the ventilation pipe 5, and the outer edge of the rectangular surface is connected to the channel, wherein the first fan-shaped surface and the second fan-shaped surface correspond to the cross-sectional portion of the liquid absorption part 24, and the rectangular surface corresponds to the cross-sectional portion of the atomization part 23.
