DETAILED DESCRIPTION

[0073] The present application is further described in detail below by specific embodiments in conjunction with the accompanying drawings. Wherein similar elements in different embodiments adopt associated similar element numbers. In the following embodiments, many detailed descriptions are intended to enable the present application to be better understood. However, those skilled in the art can easily recognize that some of the features can be omitted in different situations, or can be replaced by other elements, materials, and methods. In some cases, some operations related to the present application are not shown or described in the specification, in order to avoid the core part of the present application being overwhelmed by too much description, and for those skilled in the art, it is not necessary to describe these related operations in detail, and they can fully understand the related operations based on the description in the specification and the general technical knowledge in the art.

[0074] In addition, the features, operations or characteristics described in the specification can be combined in any appropriate manner to form various implementations. At the same time, the steps or actions in the method description can also be interchanged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the various sequences in the specification and the drawings are only for the purpose of clearly describing a certain embodiment and are not meant to be a required sequence, unless otherwise specified that a certain sequence must be followed.

[0075] The serial numbers of the components in this document, such as "first", "second", etc., are only used to distinguish the objects described and do not have any order or technical meaning. The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).

[0076] In one embodiment, please refer to Figure 1 The atomization device includes an atomizer 1 and a power supply assembly 2, and the power supply assembly 2 supplies power to the atomizer 1. In one embodiment, the power supply assembly 2 includes a component shell and a battery in the component shell. The atomizer 1 and the power supply assembly 2 can be detachably connected, such as by snap connection, magnetic attraction, etc.; the atomizer 1 and the power supply assembly 2 can also be integrated in the same housing.

[0077] Please refer to Figure 2 and Figure 3 The atomizer 1 includes an atomizer shell 11 and an atomizer core 12. The atomizer core 12 is disposed in the atomizer shell 11. The atomizer shell 11 has a liquid storage chamber 111 for supplying liquid to the atomizer core 12. The atomizer 1 also includes a suction nozzle 13. The suction nozzle 13 is disposed on the atomizer shell 11.

[0078] Please refer to Figures 3 to 5The atomizing core 12 includes an outer support 121, an atomizing tube 122, a liquid storage element 123, a heating element 124 and a liquid guiding element 125. The outer support 121 has a first liquid passage 126, and the atomized matrix in the liquid storage chamber 111 can enter the outer support 121 through the first liquid passage 126. At least part of the atomizing tube 122 is in the outer support 121, and an airflow channel 127 for airflow to pass through is formed in the atomizing tube 122. When the atomizer 1 is inhaled, the aerosol generated in the airflow channel 127 can be drawn out. The tube wall of the atomizing tube 122 has a second liquid passage 128 for the atomized matrix to enter. After the atomized matrix enters the outer support 121 through the first liquid passage 126, it can enter the atomizing tube 122 through the second liquid passage 128. At least part of the heating element 124 is located in the air flow channel 127 , so that the atomized substrate contacts the heating element 124 after entering the atomization tube 122 , and the heating element 124 can heat the atomized substrate to generate an aerosol.

[0079] The liquid storage element 123 is at least partially disposed in the outer support 121 and between the atomizing tube 122 and the outer support 121. The liquid storage element, the first liquid passage and the second liquid passage form a liquid guide path 15 (only part of the liquid guide path is shown in the figure) for the atomized matrix to enter the atomizing tube. In one embodiment, the liquid storage element 123 covers the first liquid passage 126 to be able to absorb the atomized matrix entering the outer support 121. The liquid storage element 123 covers the second liquid passage 128 to enable the atomized matrix to enter the atomizing tube 122.

[0080] The liquid guide element 125 is disposed in the atomizing tube 122, and is used to absorb the atomized matrix through the liquid guide path 15. A small amount of atomized matrix can be stored in the atomizing core 12 through the adsorption effect of the liquid storage element 123, so that when the atomizer 1 is inhaled, the heating element 124 in the atomizing core 12 can be kept in contact with the atomized matrix, and the liquid guide element 125 and the liquid storage element 123 can reduce the amount of liquid that increases the internal leakage due to the atomized matrix flowing out of the liquid storage chamber 111 too quickly.

[0081] Please refer to Figure 7 In order to make the atomized matrix enter the liquid storage element 123 more uniformly, the first liquid passage 126 includes a first portion 1261 and a second portion 1262. The first portion 1261 extends in a long strip shape along a first direction on the outer surface of the outer bracket 121, and the second portion 1262 extends in a long strip shape along a second direction on the outer surface of the outer bracket 121. The first portion 1261 and the second portion 1262 form an angle. Since the first portion 1261 and the second portion 1262 are both long strips and extend in different directions, the first portion 1261 and the second portion 1262 cover a larger area, so that the atomized matrix can enter the liquid storage element 123 more uniformly.

[0082] It should be noted that the heating element 124 in the present application can adopt any feasible structure. For example, in one embodiment, the heating element 124 is a spiral heating wire, which extends along the air flow channel 127 and contacts the heat-conducting element. For another example, in one embodiment, the heating element 124 is a conductive mesh (conductive metal mesh), which is a hollow columnar mesh. Compared with the spiral heating wire, the heating is more uniform and the atomization amount is easily increased.

[0083] Regarding the form of the liquid-conducting element 125, in one embodiment, the liquid-conducting element 125 can be liquid-conducting cotton or liquid-conducting ceramics, and the liquid-conducting ceramics are microporous ceramics. Of course, in addition to liquid-conducting ceramics, other microporous liquid-conducting structures can also be used. In one embodiment, please refer to Figure 3 , the heating element 124 is attached to the inner side of the liquid conducting element 125. In some other embodiments, the heating element 124 can be embedded in the heat conducting element.

[0084] In one embodiment, the liquid storage element 123 may be made of liquid storage cotton. In addition to liquid storage cotton, in some other embodiments, the liquid storage element 123 may also be made of other porous materials, such as porous ceramics, porous graphite, liquid storage sponge, etc.

[0085] Furthermore, in one embodiment, the first portion 1261 intersects with the second portion 1262, so that the first portion 1261 and the second portion 1262 are interconnected, which facilitates processing and covers a larger area.

[0086] For further information, please refer to Figure 7 In one embodiment, the number of the first parts 1261 is at least two, and the two ends of the second part 1262 intersect with the two first parts 1261 respectively. Figure 3 and Figure 7 The first liquid passage 126 is a through hole. In some other embodiments, the first liquid passage 126 may also be a groove opened on the outer bracket 121 and extending to the end of the outer bracket 121 and penetrating the outer bracket tube hole.

[0087] Further, in one embodiment, the two first portions 1261 intersecting with the same second portion 1262 extend in the same direction, and the intersection of the second portion 1262 and the first portion 1261 is located near the midpoint of the first portion 1261. Figure 7 The first liquid passage 126 is in an “I” shape.

[0088] The first liquid passage 126 may be in any other feasible shape, for example, the first liquid passage 126 may be in an "X" shape, a "T" shape, a "Z" shape, etc. Of course, in some other embodiments, the first portion 1261 and the second portion 1262 may also be independent of each other, that is, the first portion 1261 and the second portion 1262 are not intercommunication, and in this case, the first portion 1261 and the second portion 1262 may be two independent elliptical holes.

[0089] In one embodiment, the outer support 121 is tubular, the first portion 1261 extends along the circumference of the outer support 121, and the second portion 1262 extends along the axial direction of the outer support 121. In some other embodiments, the first portion 1261 may also extend along any other direction.

[0090] It should be noted that the first direction and the second direction in the present application are not limited to the straight line direction. For example, when the outer bracket is tubular, the first direction in the above embodiment is the circumferential direction of the outer bracket, and the second direction is the axial direction of the outer bracket. For another example, the first direction can also be a direction along a certain curve, and similarly, the second direction can also be a direction along a certain curve. The first direction and the second direction are at an angle, which means that the first direction and the second direction extend in different directions respectively, so that the first liquid passage covers more areas.

[0091] In one embodiment, the number of the first liquid passage 126 is one or more than two. Figure 7 When there are more than two first liquid passage channels 126, the first liquid passage channels 126 may be evenly spaced along the circumference of the outer support 121. Of course, in one embodiment, when there are more than one first liquid passage channels 126, the first liquid passage channels 126 may be arranged in two rows, and the two rows of first liquid passage channels 126 are arranged along the axial direction of the outer support 121.

[0092] In one embodiment, please refer to Figure 5 The second liquid passage 128 may be a hole on the wall of the atomizing tube 122, and the hole may be a regular hole or a special-shaped hole. In one embodiment, the second liquid passage 128 may also be a groove on the wall of the atomizing tube 122 and connected to the tube opening of the atomizing tube 122.

[0093] After the atomized matrix in the liquid storage chamber 111 flows out, negative pressure is easily formed in the liquid storage chamber 111, which will hinder the outflow of the atomized matrix. In order to make the atomized matrix flow out smoothly, in one embodiment, please refer to Figure 3The atomizing tube 122 has a ventilation hole 1221, which is communicated with the first liquid passage 126, and connects the first liquid passage 126 with the air flow passage 127, so that the gas in the air flow passage 127 can enter the first liquid passage 126 through the ventilation hole 1221 and then enter the liquid storage chamber 111, so that the atomized matrix in the liquid storage chamber 111 can flow out smoothly.

[0094] In order to facilitate the installation of the atomizing tube 122, in one embodiment, please refer to Figure 3 , the ventilation hole 1221 connects the air flow channel 127 and the first part 1261. The ventilation hole 1221 and the first part 1261 are opposite to each other along the extension direction of the ventilation hole 1221, so that the path between the ventilation hole 1221 and the first part 1261 is the shortest, which is more conducive to the gas entering the first part 1261 from the ventilation hole 1221. In one embodiment, the first part 1261 is along the circumference of the outer bracket 121. During installation, the ventilation hole 1221 is allowed to have a position deviation in the circumferential direction, thereby reducing the position accuracy requirement for the atomizer tube 122. Of course, in some other embodiments, the ventilation hole 1221 and the first part 1261 are staggered, and it is also feasible that the ventilation hole 1221 faces the inner wall of the outer bracket 121.

[0095] In one embodiment, please refer to Figure 3 and Figure 4 , the ventilation hole 1221 is arranged downwardly, and the ventilation hole 1221 is located at the lower side of the liquid guide element 125. In one embodiment, the ventilation hole 1221 is close to the first end 1222 of the atomizing tube 122 and away from the second end 1223 of the atomizing tube 122, wherein the first end 1222 is away from the suction nozzle 13, and the second end 1223 is close to the suction nozzle 13.

[0096] Of course, in some other embodiments, the ventilation hole 1221 may also be opposite to the second portion 1262 along the radial direction of the outer bracket 121 .

[0097] In one embodiment, please refer to Figure 3 , Figure 4 and Figure 8 The number of the ventilation holes 1221 is more than two, specifically, three, four or more than five. The ventilation holes 1221 are evenly spaced along the circumference of the atomizing tube 122. In some other embodiments, the number of the ventilation hole 1221 may also be one.

[0098] It should be noted that the conduction, communication and connection forms described in the present application are not limited to empty channels that allow the atomized matrix or gas to pass through, but also include filling the channels with porous materials that allow the atomized matrix or gas to pass through.

[0099] Due to the condensation in the atomizer core 12, the atomizer matrix may also have internal leakage. When there is a lot of internal leakage and a lot of condensed liquid, it is easy to leak out, affecting the user experience.
