Referring to fig. 1, fig. 2 and fig. 3, fig. 1 is a schematic structural diagram of an atomizer 10 according to some embodiments, fig. 2 is a schematic sectional diagram of an atomizer 110 according to some embodiments, and fig. 3 is a schematic sectional diagram of the atomizer 110 according to some embodiments from another angle. Wherein the cross sections shown in fig. 2 and 3 are perpendicular to each other. In some embodiments, the nebulizing device 10 comprises a nebulizer 110 and a power assembly 120, the power assembly 120 being for powering the nebulizer 110 such that the nebulizer 110 is capable of nebulizing an aerosol-generating substrate to form an aerosol for inhalation by a user. It can be understood that fig. 1 does not show a specific structure of the power supply assembly 120, and in fact, the power supply assembly 120 may include a housing and a battery cell, a circuit board, and the like contained in the housing, and the housing of the power supply assembly 120 may be integrally formed with the housing of the atomizer 110, or may be connected to each other by welding, fastening, interference fit, and the like, which is not repeated herein.

Further, as shown in connection with fig. 2, 4 and 5, in some embodiments, the atomizer 110 comprises a housing 1110 and an atomizing core 1120 and a cap 1130 provided within the housing 1110, the atomizing core 1120 being at least partially housed within the cap 1130, the atomizing core 1120 serving to atomize the aerosol-generating substrate within the cap 1130 to form an aerosol for inhalation by a user. An air inlet channel 1111 and an air outlet channel 1112 are arranged in the shell 1110, the top cover 1130 is provided with an inner wall 1131 facing the atomizing core 1120 and an outer wall 1134 facing away from the atomizing core 1120, and an air groove 1135 communicating the air inlet channel 1111 and the air outlet channel 1112 is concavely arranged on the inner wall 1131 of the top cover 1130. The aerosol formed inside the top cover 1130 is driven by the airflow entering the top cover 1130 from the air inlet channel 1111, and can flow to the air outlet channel 1112 through the air groove 1135, and then flow out of the atomization device 10 through the air outlet channel 1112 for the user to suck.

It should be noted that, the air groove 1135 is disposed on the inner wall 1131 of the top cover 1130, which means that the aerosol flowing in the air groove 1135 is located inside the top cover 1130 before reaching the air outlet channel 1112 or when the aerosol flows back to the area where the top cover 1130 is located after reaching the air outlet channel 1112 due to various reasons, and does not diffuse between the top cover 1130 and the housing 1110. Of course, the air channel 1135 may directly communicate with the air inlet channel 1111 and the air outlet channel 1112, and the air channel 1135 may also communicate with the air inlet channel 1111 and the air outlet channel 1112 through other spaces such as a groove body and a cavity inside the top cover 1130.

In addition, the cap 1130 may be any regular or irregular shape, and the mating relationship of the atomizing core 1120 and the cap 1130 is not limited, so long as the atomizing core 1120 is capable of atomizing the aerosol-generating substrate within the cap 1130 to form an aerosol. For example, the top cover 1130 may be a hollow structure, and the atomizing core 1120 is disposed in the inner space of the top cover 1130, so that the inner side surface of the top cover 1130 may be an inner wall 1131 of the top cover 1130, and the outer side surface of the top cover 1130 may be an outer wall 1134 of the top cover 1130. Of course, the atomizing core 1120 may also be partially located in the inner space of the top cover 1130, and another portion of the atomizing core may be coupled to the top cover 1130 by means of connection, abutment, insertion, or the like.

In the atomizer 110, the aerosol formed inside the top cover 1130 flows to the air outlet channel 1112 through the air groove 1135, in other words, the aerosol flows inside the top cover 1130 before flowing to the air outlet channel 1112, and does not enter between the top cover 1130 and the housing 1110, so that the diffusion range of the aerosol can be effectively reduced, the aerosol is more concentrated, and the aerosol residue and the formation of condensate are reduced. Meanwhile, due to the arrangement of the air groove 1135, the condensate formed in the aerosol flowing process cannot be diffused to the space outside the top cover 1130, so that the condensate can be limited in the inner space of the top cover 1130 and the air outlet channel 1112, the condensate can more easily flow back to the atomizing core 1120 in the top cover 1130, and the risk of leakage of the condensate is reduced.

The number and the arrangement position of the air grooves 1135 are not limited as long as the air inlet channel 1111 and the air outlet channel 1112 can be communicated, so that the aerosol can flow from the inside of the top cover 1130 to the air outlet channel 1112. Specifically, in some embodiments, the air grooves 1135 may be provided with one or at least two, and when the air grooves 1135 are provided with at least two, the at least two air grooves 1135 may be provided at intervals along the circumference of the top cover 1130. Where the axial direction of top cover 1130 can be parallel to the centerline of gas outlet channel 1112, i.e. parallel to the axis of gas outlet channel 1112, the circumferential direction of top cover 1130 can be understood as the direction around the centerline of gas outlet channel 1112.

More specifically, in some embodiments, the atomizing core 1120 includes a first surface 1121 facing the outlet channel 1112, a second surface 1122 facing the inlet channel 1111, and a plurality of side surfaces 1123 between the first surface 1121 and the second surface 1122. When one of the air grooves 1135 is provided, the air groove 1135 faces one of the side surfaces 1123 of the atomizing core 1120. When at least two air grooves 1135 are provided, at least two air grooves 1135 face different sides 1123 of the atomizing core 1120, respectively, or part or all of the air grooves 1135 face the same side 1123 of the atomizing core 1120. The air channel 1135 faces the side 1123 of the atomizing core 1120, and the aerosol flows through the atomizing core 1120 when flowing in the air channel 1135, so that the condensate formed in the aerosol channel 1135 is more easily absorbed by the atomizing core 1120, and the risk of leakage of the condensate is reduced.

The shape of the atomizing core 1120 is not limited, and a plurality of side surfaces 1123 of the atomizing core 1120 may be sequentially arranged along the circumference of the top cover 1130, and the first surface 1121 and the second surface 1122 may be parallel to each other or inclined to each other. For example, the atomizing core 1120 may have a substantially rectangular parallelepiped shape, and the atomizing core 1120 includes four side surfaces 1123 facing different directions, and the four side surfaces 1123 are sequentially connected to the first surface 1121 and the second surface 1122, respectively. Of course, the number of the side surfaces 1123 may be three, five or other numbers, the side surfaces 1123 may be inclined or perpendicular to the first surface 1121 and the second surface 1122, and the side surfaces 1123 and the first surface 1121 and the second surface 1122 may be connected by other surfaces, which will not be described herein.

In some embodiments, a reservoir 1113 for storing the aerosol-generating substrate is also provided within the housing 1110, the cap 1130 is also provided with an inlet 1136 communicating with the reservoir 1113, and the atomizing wick 1120 is partially exposed to the reservoir 1113 via the inlet 1136. For example, in some embodiments, the first surface 1121 of the atomizing core 1120 facing the air outlet channel 1112 is exposed in the reservoir 1113, and then the first surface 1121 may be an absorption surface of the atomizing core 1120, and other surfaces such as the second surface 1122 not exposed in the reservoir 1113 may be an atomizing surface of the atomizing core 1120. Specifically, the atomizing core 1120 may include a liquid guiding member and a heat generating member (not shown) disposed on a side of the liquid guiding member (not shown) opposite to the air outlet channel 1112, and the aerosol-generating substrate in the reservoir 1113 enters the atomizing core 1120 from the first surface 1121 and is heated and atomized by the heat generating member at the second surface 1122 of the atomizing core 1120 to form an aerosol. It can be understood that, in the present embodiment, the second surface 1122 of the atomizing core 1120 and the inner wall 1131 of the top cover 1130 define an atomizing cavity 1137, the air groove 1135 directly communicates with the atomizing cavity 1137, and the aerosol is formed in the atomizing cavity 1137 and can flow to the air outlet channel 1112 through the air groove 1135.

Further, in some embodiments, there are two air grooves 1135, the openings of the two air grooves 1135 correspond to the two side surfaces 1123 facing away from the atomizing core 1120, and the two air grooves 1135 are symmetrically arranged about the center line of the air outlet channel 1112. So set up, the aerosol that forms in the atomizing chamber 1137 flows to air outlet channel 1112 from the both sides that atomizing core 1120 is carried on the back mutually, and two air grooves 1135 can enough in time derive the top cap 1130 with the aerosol that forms in atomizing chamber 1137 different positions, also are favorable to making the aerosol can not too spread, and then are favorable to reducing the formation of the residue of aerosol and condensate. It should be noted that, when the air channel 1135 is formed by recessing the inner wall 1131 of the top cover 1130, the orientation of the surface of the recessed portion of the inner wall 1135 can be understood as the orientation of the opening of the air channel 1135.

Of course, the number of the air grooves 1135 and the relative positions of the air grooves 1135 and the atomizing core 1120 may also be other arrangements, for example, two opposite sides of the atomizing core 1120 are respectively provided with a plurality of air grooves 1135, or two opposite sides of the atomizing core 1120 are provided with one air groove 1135 on one side and a plurality of air grooves 1135 on the other side, which may be specifically set according to the shapes and sizes of the top cover 1130 and the atomizing core 1120 and the flow rate of the aerosol, and will not be described herein again.

In some embodiments, the cross-section of the inner wall 1131 of the top cover 1130 includes two opposing long edges 1132 and two opposing short edges 1133, and the air grooves 1135 are disposed on the long edges 1132 of the inner wall 1131. So configured, the long edges 1132 of the inner wall 1131 of the top cover 1130 can provide enough space to position the air grooves 1135 so that the air grooves 1135 have a sufficient width for the flow of aerosol. Simultaneously, locate the long limit 1132 of top cap 1130 inner wall 1131 with air duct 1135, air duct 1135's setting can not increase the size of minor face 1133 to be favorable to compressing the size of top cap 1130 in the minor face 1133 orientation, and then reduce the occupation space of top cap 1130. It should be noted that the description of the long side 1132 and the short side 1133 of the inner wall 1131 can be understood that the dimension of the top cover 1130 in the direction of the short side 1133 is smaller than that of the top cover 1130 in the direction of the long side 1132, in other words, the long side 1132 and the short side 1133 can be understood as a definition of the dimensional relationship of the top cover 1130 in two directions, not a definition of the shape of the top cover 1130. In practice, the long edge 1132 and the short edge 1133 may each be an arc or a straight line.

For example, in some embodiments, the cross-section of the inner wall 1131 of the top cover 1130 may be substantially elliptical, such that the cross-section of the inner wall 1131 has a short axis and a long axis, the portions on both sides of the long axis may be regarded as long edges 1132, the portions on both sides of the short axis may be regarded as short edges 1133, and the long edges 1132 and the short edges 1133 are both arcs. In other embodiments, the inner wall 1131 of the top 1130 may also be generally rectangular in cross-section, such that the long edge 1132 and the short edge 1133 are both straight. Of course, the cross-section of the inner wall 1131 of the top cover 1130 may also be any other suitable regular or irregular shape, as long as the size of the top cover 1130 in one direction is larger than that in the other direction, and the description thereof is omitted.

Referring to fig. 2 and 5, in some embodiments, the inner wall 1131 of the top cover 1130 is further provided with a protrusion 1140, the protrusion 1140 is disposed between the atomizing core 1120 and the air outlet channel 1112, and the surface of the protrusion 1140 facing the atomizing core 1120 corresponds to the end position of the air groove 1135. Specifically, the surface of the bump 1140 facing the atomizing core 1120 may be inclined or perpendicular to the extending direction of the air groove 1135, i.e., inclined or perpendicular to the centerline of the air outlet channel 1112. Therefore, when the aerosol flows to the projection 1140 through the two air grooves 1135, the projection 1140 is turned toward the surface of the atomizing core 1120, so that the aerosol is converged toward the center line of the air outlet channel 1112 and enters the air outlet channel 1112, which is beneficial to make the aerosol entering the air outlet channel 1112 through the top cover 1130 more concentrated.

Referring also to fig. 4, 5, and 6, fig. 6 is a cross-sectional view of another angle of the top 1130 in some embodiments. In some embodiments, the inner wall 1131 of the top cover 1130 is further provided with a sealing member 1150, and the sealing member 1150 is hermetically connected to the atomizing core 1120, in other words, the sealing member 1150 separates the air groove 1135 from the space outside the top cover 1130 at the atomizing core 1120, so as to prevent the aerosol from diffusing to the outside of the top cover 1130 during the process of flowing to the air outlet channel 1112 through the air groove 1135. Specifically, the sealing element 1150 may be disposed on a side of the atomizing core 1120 facing the air outlet channel 1112, and when the aerosol flows along the air groove 1135 to the side of the atomizing core 1120 facing the air outlet channel 1112, the aerosol is guided to the air outlet channel 1112 by the sealing element 1150, which can both prevent the aerosol from diffusing to the outside of the top cover 1130 and facilitate the aerosol to flow to the air outlet channel 1112 more intensively.

The manner in which the seal 1150 seals the atomizing core 1120 is not limited, for example, the seal 1150 abuts the first surface 1121 of the atomizing core 1120. Of course, the sealing element 1150 may be embedded in the atomizing core 1120, or the sealing element 1150 and the atomizing core 1120 may be connected in a sealing manner by other members such as a sealing ring, as long as the aerosol is prevented from being diffused to the outside of the top cover 1130.

Further, in some embodiments, there are at least two seals 1150, a plurality of seals 1150 are spaced apart, and the plurality of seals 1150 define an air channel 1151 that communicates with the air channel 1135 and the air outlet channel 1112. The plurality of sealing elements 1150 which are arranged at intervals are arranged, the plurality of sealing elements 1150 can be matched with each other to guide the aerosol, so that the aerosol can flow to the air outlet channel 1112 through the air channel 1151 between the plurality of sealing elements 1150 after flowing to the tail end of the air channel 1135 through the air channel 1135, and the aerosol can be prevented from being diffused to the outside of the top cover 1130 and can be more concentrated.

Further, in some embodiments, two seals 1150 are provided on opposite sides of the air outlet channel 1112, and the two seals 1150 are symmetrically provided about a center line of the air outlet channel 1112. The opposing surfaces of the two seals 1150 define an air channel 1151, in other words, the air channel 1151 is located between the two seals 1150. The aerosol formed in the atomizing cavity 1137 flows through the two air grooves 1135 to the side of the atomizing core 1120 facing the air outlet channel 1112, and then flows to the air outlet channel 1112 after converging through the air channel 1151.

The shape and arrangement of the sealing member 1150 are not limited, and in the embodiment shown in fig. 5, the sealing member 1150 is substantially Y-shaped, which is beneficial to improve the connection strength between the sealing member 1150 and the top cover 1130, and the sealing member 1150 may also be substantially square, V-shaped, or any other regular or irregular shape as long as it can seal the atomizing core 1120. In some embodiments, the seal 1150 is a protrusion protruding from the inner wall 1131 of the top cover 1130 toward the atomizing core 1120, and the seal 1150 may be integrally formed with the top cover 1130 or may be connected to the top cover 1130 by welding, snapping, or the like.

It should be noted that, in some embodiments, a schematic view of just one half of the top cover 1130 is illustrated in fig. 6, and the top cover 1130 has an axisymmetric structure with respect to the cross-section shown in fig. 6.

Referring to fig. 3 and 5, in some embodiments, the projection 1140 is further formed with a flare 1141 toward the atomizing core 1120, in other words, the inner diameter of the projection 1140 is gradually reduced in a direction from the atomizing core 1120 toward the air outlet channel 1112 along the center line of the air outlet channel 1112. Therefore, when the aerosol flows to the air outlet channel 1112 through the bump 1140, the bump 1140 can gradually compress the flow space of the aerosol, which is beneficial to make the aerosol flowing to the air outlet channel 1112 more concentrated, and further reduce the residue of the aerosol and the formation of condensate.

In some embodiments, the projection of the flared opening 1141 formed by the bump 1140 and the air outlet channel 1112 on the first surface 1121 of the atomizing core 1120 is located in the region of the first surface 1121, and then the first surface 1121 of the atomizing core 1120 is directly opposite to the flared opening 1141 and the air outlet channel 1112. Thus, the condensate formed in the bump 1140 and the air outlet channel 1112 is easily dropped onto the first surface 1121 of the atomizing core 1120 and absorbed by the atomizing core 1120, which is beneficial to reducing the risk of leakage of the condensate.

Referring to fig. 2 and 3, in some embodiments, the atomizer 110 further includes a base 1160, the base 1160 is connected to the top cover 1130 and is located on a side of the top cover 1130 away from the air outlet channel 1112, and the air inlet channel 1111 is opened on the base 1160. Base 1160 is used to seal the side of cap 1130 that faces away from air outlet channel 1112 and prevent aerosol and condensate from leaking from the side of cap 1130 that faces away from air outlet channel 1112. The air inlet channel 1111 of the base 1160 can allow external air to enter the top cover 1130, so that the aerosol formed in the top cover 1130 can flow out of the atomization device 10 through the air outlet channel 1112 for a user to suck. It will be appreciated that the atomizing chamber 1137 of the top cover 1130 is defined by the second surface 1122 of the atomizing core 1120, the inner wall 1131 of the top cover 1130, and the base 1160 together.

In some embodiments, the atomizing core 1120 further includes two electrodes 1124 electrically connected to the heat generating member, the base 1160 is further provided with two through holes 1161 corresponding to the two electrodes 1124 one by one, and the two electrodes 1124 are electrically connected to the power supply assembly 120 by passing through the corresponding through holes 1161, respectively, so that the power supply assembly 120 can supply power to the heat generating member of the atomizing core 1120, so that the heat generating member can atomize the aerosol generating substrate to form aerosol. The two through holes 1161 can limit the two electrodes 1124 to assist in positioning and fixing the atomizing core 1120.

Referring to fig. 3 and 4, in some embodiments, the top cover 1130 is provided with two liquid inlets 1136, two end portions of the atomizing core 1120 are respectively exposed to the liquid storage compartment 1113 through the liquid inlets 1136, and a middle portion of the atomizing core 1120 is opposite to the air outlet channel 1112. The top cover 1130 is further provided with two liquid guide surfaces 1138, the liquid guide surfaces 1138 are inclined to the axial direction of the top cover 1130, the two liquid guide surfaces 1138 correspond to the two liquid inlets 1136 one by one, and the bottoms of the two liquid guide surfaces 1138 correspond to the positions of the two side surfaces 1123, which are opposite to the atomizing core 1120, respectively. The liquid guiding surface 1138 is arranged to guide the aerosol generating substrate in the liquid storage bin 1113 to the atomizing core 1120, so that the atomizing core 1120 can absorb the aerosol generating substrate, and the aerosol in the top cover 1130 can be formed more smoothly.

In some embodiments, a portion of the housing 1110 is made of a transparent material to facilitate viewing of the remaining amount of aerosol-generating substrate in the reservoir 1113, and the cover 1130 is made of an opaque material. From this, adopt foretell top cap 1130 in atomizer 110, because aerosol can not spread the space between top cap 1130 and casing 1110 to be difficult to form the condensate on casing 1110, avoid the user to observe the condensate outside casing 1110 and cause the illusion that the condensate was revealed, promote atomizing device 10's use and experience.
