Patent Description:
An atomizer is a device that atomizes liquid (such as e-liquid) into gases or tiny particles, and is widely used in apparatuses such as medical equipment, or an electronic atomizing device.

Currently, the atomizer generally includes a bottom plate, an atomization base, and an atomization core. The atomization base is covered on the bottom plate and cooperates with the bottom plate to form an atomization cavity. The atomization core is accommodated in the atomization cavity for heating and atomizing the liquid in the atomization cavity when energized. Specifically, air inlet holes are also defined on the bottom plate, and one end of each air inlet hole is in communication with external air, and the other end is in communication with the atomizer, so that the external air can enter the atomization cavity through the air inlet holes.

However, a large amount of liquid will accumulate on one side surface of the bottom plate facing the atomization base during use of an existing atomizer, and will leak out through the air inlet holes of the bottom plate, resulting in liquid leakage.

<CIT> discloses an electronic atomization device and an atomizer thereof. The atomizer includes an atomization cavity and an air outlet channel communicated with the atomization cavity. A liquid storage structure is arranged at the bottom of the atomization cavity; the liquid storage structure is communicated with the atomization cavity and comprises at least one second liquid suction groove opposite to the atomization cavity; and the second liquid suction groove absorbs the liquid medium leaked from the atomization cavity and/or the air outlet channel through capillary acting force.

The present disclosure provides a liquid guiding structure according to claim <NUM>, an atomizer according to claim <NUM> and an electronic atomizing device according to claim <NUM>. The present disclosure can resolve a problem that a large amount of liquid will accumulate on one side surface of a bottom plate facing an atomization base during use of an existing atomizer, and will leak out from air inlet holes of the bottom plate, resulting in liquid leakage.

The liquid guiding structure includes the bottom plate, by arranging the bottom plate and arranging the first liquid guiding portion on the first surface of the bottom plate, the first liquid guiding portion cooperates with the first surface of the bottom plate to form at least one first liquid guiding channel. In addition, the second liquid guiding portion is arranged on the first surface of the bottom plate, at least one second liquid guiding channel is defined on the second liquid guiding portion, one end of the second liquid guiding channel is in communication with the first liquid guiding channel, and the transverse dimension of the first liquid guiding channel gradually decreases in the direction toward the second liquid guiding portion. In this way, the capillary force of the first liquid guiding channel increases gradually in the direction toward the second liquid guiding portion, and the gradually increasing capillary force is used to absorb and guide the liquid on the first surface of the bottom plate. Moreover, the capillary force of the second liquid guiding channel is greater than the capillary force of the first liquid guiding channel, so that the liquid absorbed by the first liquid guiding portion by the capillary force of the first liquid guiding channel is guided to the second liquid guiding portion. Therefore, the liquid on the bottom plate is stored to greatly reduce the probability of liquid leakage of the atomizer.

Structures and functions of these components are the same as or similar to those in the related art, and for details, reference may be made to the related art, which are not described herein again.

In some embodiments, referring to <FIG> and <FIG>, <FIG> is a schematic structural view of an atomizer according to an embodiment of the present disclosure; and <FIG> is a schematic view of a local structure of A in <FIG>. The atomizer <NUM> includes a bottom plate 11a, an atomization base 11b, an atomization core <NUM>, and a liquid guiding assembly 141b.

The bottom plate 11a may be a horizontal plate and has a first surface and a second surface arranged opposite to the first surface. The atomization base 11b is covered on the first surface of the bottom plate 11a and cooperates with the first surface of the bottom plate 11a to form an atomization cavity <NUM>. In some embodiments, the atomization base 11b includes a sidewall and a top wall that cooperate to form a concave-shaped structure, and the concave-shaped atomization base 11b cooperates with the first surface of the bottom plate 11a to form the atomization cavity <NUM>. The atomization core <NUM> is accommodated in the atomization cavity <NUM> for heating and atomizing liquid in the atomization cavity <NUM> when energized. The liquid guiding assembly 141b is configured to absorb liquid on the bottom plate 11a.

In some embodiments, the electronic atomizing device <NUM> includes a liquid storage cavity <NUM> configured to store liquid. Liquid flowing holes are defined on the top wall of the atomization base 11b. One end of each liquid flowing hole is in communication with the liquid storage cavity <NUM>, and the other end of each liquid flowing hole is in communication with the atomization cavity <NUM>. A plurality of liquid absorbing holes are defined on the atomization core <NUM>. One end of each liquid absorbing hole is in communication with a liquid flowing hole, and the other end of each liquid absorbing hole is in communication with the atomization cavity <NUM>, so that the liquid in the liquid storage cavity <NUM> may flow to the surface of the atomization core <NUM> through the liquid flowing holes and the liquid absorbing holes. In some embodiments, the atomization core <NUM> is arranged on the liquid guiding assembly 141b, so that the liquid guiding assembly 141b supports the atomization core <NUM>, and the side surface of the atomization core <NUM> away from the liquid guiding assembly 141b abuts against the top wall of the atomization base 11b to prevent liquid leakage. In an embodiment, the atomization core <NUM> may be porous ceramic, and the micro pores of the atomization core <NUM> form the liquid absorbing holes.

In some embodiments, the atomizer <NUM> includes a heating body <NUM> arranged on the side surface of the atomizer core <NUM> away from the atomization base 11b for heating and atomizing liquid on the surface of the atomizer core <NUM> when energized, and in some embodiments, the heating body <NUM> may be a heating film arranged on the surface of the atomizer core <NUM>.

In some embodiments, referring to <FIG>, <FIG> is a schematic structural view of an atomization base according to a first embodiment of the present disclosure, <FIG> is a top view of <FIG>, and <FIG> is a schematic plan view of a first liquid guiding portion and a second liquid guiding portion according to an embodiment of the present disclosure. The liquid guiding assembly 141b includes a first liquid guiding portion <NUM> and a second liquid guiding portion <NUM>. In an embodiment, the second liquid guiding portion <NUM> is arranged on the first surface of the bottom plate 11a and is perpendicular to the first surface of the bottom plate 11a, and the atomization core <NUM> is arranged on the end of the second liquid guiding portion <NUM> away from the first liquid guiding portion <NUM>.

A boss <NUM> is arranged on the first surface of the bottom plate 11a, a plurality of air inlet holes <NUM> are defined on the boss <NUM> and extend through the upper and the lower surfaces of the boss <NUM>, and external air may enter the atomization cavity <NUM> through the air inlet holes <NUM>. By enabling end openings of ends of the air inlet holes <NUM> facing the atomization core <NUM> to be higher than the first surface of the bottom plate 11a, liquid on the first surface of the bottom plate 11a may be prevented from leaking out through the air inlet holes <NUM>. In some embodiments, the bottom plate 11a may be elliptical, the boss <NUM> is located at a central position of the elliptical bottom plate 11a. One air inlet hole <NUM> is taken as a center, the remaining air inlet holes <NUM> are evenly distributed around the air inlet hole <NUM>.

The first liquid guiding portion <NUM> is arranged on the first surface of the bottom plate 11a and cooperates with the first surface of the bottom plate 11a to form at least one first liquid guiding channel <NUM>. In an embodiment, the first liquid guiding portion <NUM> may be integrated with the bottom plate 11a, and may be made of dense ceramic. The second liquid guiding portion <NUM> is arranged on the first surface of the bottom plate 11a and has at least one second liquid guiding channel <NUM>, one end of the second liquid guiding channel <NUM> is in communication with the first liquid guiding channel <NUM>, so as to guide the liquid on the first surface of the bottom plate 11a to the atomization core <NUM> through the first liquid guiding channel <NUM> and the second liquid guiding channel <NUM>. In some embodiments, the transverse dimension of the first liquid guiding channel <NUM> gradually decreases in the direction toward the second liquid guiding portion <NUM>, so that the capillary force of the first liquid guiding channel <NUM> gradually increases in the direction toward the second liquid guiding portion <NUM>, thereby absorbing and guiding the liquid on the first surface of the bottom plate 11a by this gradually increasing capillary force. That is, an additional force is provided for the liquid on the first surface of the bottom plate 11a to flow to the second liquid guiding portion <NUM>, so that the liquid on the first surface of the bottom plate 11a may flow into the first liquid guiding channel <NUM> and flow to the second liquid guiding portion <NUM> through the second liquid guiding channel <NUM> in communication with the first liquid guiding channel <NUM>. In this way, the second liquid guiding portion <NUM> is configured to store the liquid accumulated on the first surface of the bottom plate 11a, thereby greatly reducing a probability that the liquid on the first surface of the bottom plate 11a leaks out through the inlet holes <NUM> and results in a problem of liquid leakage.

In some embodiments, the other end of the second liquid guiding channel <NUM> is in communication with the atomization core <NUM>, and the capillary force of the second liquid guiding channel <NUM> is smaller than the capillary force of the atomization core <NUM>, so as to guide the liquid on the bottom plate 11a to the atomization core <NUM> or the liquid storage cavity <NUM> in communication with the atomization core <NUM> through the first liquid guiding channel <NUM> and the second liquid guiding channel <NUM>, thereby realizing reflux of the liquid on the bottom plate 11a to improve the utilization rate of the liquid. Compared with a rectangular liquid absorbing groove in the related art, the liquid guiding channels in the present disclosure may not only greatly reduce the probability of liquid leakage, but also absorb and guide the liquid on the surface of the bottom plate 11a by the gradually increasing capillary force of a liquid guiding channel with a variable diameter, thereby effectively increasing a reflux volume of the liquid. It may be understood that a regular liquid absorbing groove with an invariable diameter (that is, the transverse dimension remains unchanged) does not have a one-way liquid guiding function, while a liquid guiding channel with a variable diameter (that is, the transverse dimension changes) may provide a force for liquid to flow from a large cross section part to a small cross section part of the channel. Because the small cross section part of the liquid guiding channel has a more apparent capillary phenomenon, the liquid may flow to the part of the liquid guiding channel with a smaller transverse dimension, thereby reducing a liquid leakage volume. The transverse dimension refers to the distance between two sidewalls of the liquid guiding channel. It may be understood that the distance is the shortest distance from any one point on one sidewall to another sidewall.

In addition, in a case that there is much liquid formed due to condensation or the like in the second liquid guiding channel <NUM>, because sizes gradually increase from the second liquid guiding channel <NUM> to the first liquid guiding channel <NUM> during a downward flowing process of the liquid, certain resistance may be applied to the downward flowing process, so as to prevent the liquid from flowing to the first surface of the bottom plate 11a, thereby facilitating the liquid to flow to the atomization core <NUM>.

In some embodiments, referring to <FIG> and <FIG>, the first liquid guiding channel <NUM> is a first liquid guiding groove defined on the first surface of the bottom plate 11a. In other embodiments, the first liquid guiding channel <NUM> may also be a first liquid guiding hole defined on the first surface of the bottom plate 11a. In some embodiments, the first liquid guiding portion <NUM> includes a first protruding portion and a second protruding portion, tops of a first protruding portion and a second protruding portion are connected to each other. In this case, the first liquid guiding channel <NUM> is the first liquid guiding hole.

In some embodiments, the first liquid guiding portion <NUM> may include a first protruding portion and a second protruding portion that are spaced apart from each other, and the first protruding portion, the second protruding portion, and the first surface of the bottom plate 11a form at least one first liquid guiding groove.

In an embodiment, the surface of the first protruding portion close to the second protruding portion is an inner arc surface, and the surface of the second protruding portion close to the first protruding portion is an outer arc surface. In this embodiment, the first protruding portion and the second protruding portion cooperate with the first surface of the bottom plate 11a to form an arc-shaped first liquid guiding groove.

In some embodiments, the first protruding portion includes two arc protrusions <NUM>, and the second protruding portion is an annular protrusion <NUM>. The two arc protrusions <NUM> are oppositely arranged on the two sides of the annular protrusion <NUM> respectively, and spaced apart from the annular protrusion <NUM>. One end of each arc protrusion <NUM> abuts against the edge of the second liquid guiding portion <NUM>, the other end of each arc protrusion <NUM> extends in the direction away from the second liquid guiding portion <NUM>, and the distance between each arc protrusion <NUM> and the annular protrusion <NUM> decreases gradually in the direction toward the second liquid guiding portion <NUM>, so that the protrusions <NUM> and the annular protrusion <NUM> cooperate with the first surface of the bottom plate 11a to form two first liquid guiding grooves. It may be understood that the distance between each arc protrusion <NUM> and the annular protrusion <NUM> is the transverse dimension of the first liquid guiding groove.

In an embodiment, the two arc protrusions <NUM> are arranged on the circular arc, and the circular arc is eccentrically arranged with the circular arc on which the annular protrusion <NUM> is arranged. That is, the center of the circular arc on which the two arc protrusions <NUM> are arranged is arranged at a different position from the center of the circular arc on which the annular protrusion <NUM> is arranged, so that the distance between each arc protrusion <NUM> and the annular protrusion <NUM> decreases gradually in the direction toward the second liquid guiding portion <NUM>.

In some embodiments, the annular protrusion <NUM> is circular ring-shaped and the surface of the annular protrusion <NUM> close to the second liquid guiding portion <NUM> includes a tangent plane, and a vertical distance between the tangent plane and the second liquid guiding portion <NUM> is smaller than the transverse dimension of the part of the first liquid guiding channel <NUM> close to the second liquid guiding portion <NUM>. In this way, the tangent plane, the second liquid guiding portion <NUM>, and the first surface of the bottom plate 11a define a channel whose transverse dimension is smaller than the transverse dimension of the first liquid guiding channel <NUM>. Therefore, the capillary force of this channel is greater than the capillary force of the first liquid guiding channel <NUM>, so as to absorb and guide liquid in the first liquid guiding channel <NUM> and enable the liquid to flow toward the channel, enter second liquid guiding channel <NUM> corresponding to the channel, and reflux to the atomization core <NUM>.

It may be understood that, in this embodiment, referring to <FIG>, the transverse dimensions of the first liquid guiding channel <NUM> and the second liquid guiding channel <NUM> gradually decrease from a position A to a position D, that is, LA > LB > LC > LD, so that liquid may be collected at the position A and guided to a position B. After this, a part of the liquid flows to the position D through a first second liquid guiding channel <NUM> to reflux to the atomization core <NUM>, while other part of the liquid flows to other second liquid guiding channels <NUM> through a channel corresponding to a position C, so as to reflux to the atomization core <NUM> through another second liquid guiding channel <NUM> rather than the first second liquid guiding channel <NUM>. The liquid thereby refluxes from the first surface of the bottom plate 11a to the atomization core <NUM>.

In some embodiments, as experiment results show, after dripping liquid to the first surface of the bottom plate 11a, one end of the first liquid guiding channel <NUM> away from the second liquid guiding portion <NUM> may guide the liquid into the first liquid guiding channel <NUM>, and the liquid may flow smoothly to a second liquid guiding channel <NUM> closest to the first liquid guiding channel <NUM>. After filling the closest second liquid guiding channel <NUM>, the liquid flows to a second liquid guiding channel <NUM> slightly from the first liquid guiding channel <NUM> through the channel corresponding to the position C until all the second liquid guiding channels <NUM> are filled.

In an embodiment, referring to <FIG> and <FIG>, <FIG> is a schematic structural view of an atomization base according to a second embodiment of the present disclosure, and <FIG> is a top view of <FIG>. The tangent plane of the annular protrusion <NUM> abuts against the second liquid guiding portion <NUM> to form two independent first liquid guiding channels <NUM>. In this way, the liquid on the first surface of the bottom plate 11a may be dealt with at different positions, so that liquid passing through a particular first liquid guiding channel <NUM> may reflux to the atomization core <NUM> through a plurality of second liquid guiding channels <NUM> in communication with the particular first liquid guiding channel <NUM>. Moreover, the second liquid guiding channels <NUM> may be fully used to avoid a problem that the liquid accumulates in second liquid guiding channels <NUM> at the edge of the second liquid guiding portion <NUM> but does not pass through second liquid guiding channels <NUM> in the middle of the second liquid guiding portion <NUM>. In addition, a flow path of the liquid may be shortened, thereby greatly enhancing the reflux efficiency and reducing the probability of liquid leakage. In addition, the two first liquid guiding channels <NUM> are defined independently, so as to avoid a problem that the liquid on the first surface of the bottom plate 11a enters one first liquid guiding channel <NUM> and then flows out to the first surface of the bottom plate 11a through the other first liquid guiding channel <NUM> in communication with the first liquid guiding channel <NUM>. In some embodiments, each first liquid guiding channel <NUM> is at least in communication with two second liquid guiding channels <NUM>.

In another embodiment, referring to <FIG>, <FIG> is a schematic structural view of an atomization base according to a third embodiment of the present disclosure, <FIG> is a top view of <FIG>, and <FIG> is a schematic plan view of a first liquid guiding portion and a second liquid guiding portion according to another embodiment of the present disclosure. The first liquid guiding portion <NUM> includes a baffle <NUM>, the annular protrusion <NUM> and the second liquid guiding portion <NUM> are spaced apart from each other, and the baffle <NUM> is arranged between the annular protrusion <NUM> and the second liquid guiding portion <NUM> to space the two first liquid guiding channels <NUM> apart from each other by the baffle <NUM>, thereby forming two independent first liquid guiding channels <NUM>, each first liquid guiding channel <NUM> is at least in communication with two second liquid guiding channels <NUM>.

In some embodiments, the baffle <NUM> is arranged between the tangent plane of the annular protrusion <NUM> and the second liquid guiding portion <NUM> and may be a rectangular plate.

In some embodiments, the annular protrusion <NUM> is a mounting base <NUM> for an electrode ejector pin and is configured to mount the electrode ejector pin.

In some embodiments, referring to <FIG>, the foregoing second liquid guiding channels <NUM> extend from the end of the second liquid guiding portion <NUM> to the first surface of the bottom plate 11a, and the transverse dimension of the second liquid guiding channels <NUM> is smaller than that of ends of the first liquid guiding channels <NUM> close to the second liquid guiding portion <NUM>. In some embodiments, the transverse dimension of the second liquid guiding channels <NUM> is smaller than that of the first liquid guiding channel <NUM>, so as to absorb and guide the liquid in the first liquid guiding channel <NUM> and enable the liquid to flow in the direction toward the second liquid guiding channels <NUM> and to flow to the atomization core <NUM>. The second liquid guiding channels <NUM> extend from the end of the second liquid guiding portion <NUM> to the first surface of the bottom plate 11a, so that liquid at any position on the first surface of the bottom plate 11a may fully use the second liquid guiding channels <NUM>.

In some embodiments, the second liquid guiding portion <NUM> is made of porous material. For example, the second liquid guiding portion <NUM> may be made of porous ceramic, and the micro pores of the second liquid guiding portion <NUM> form the second guiding channels <NUM>, that is, the liquid in the first liquid guiding channels <NUM> flows to the atomization core <NUM> through the micro pores of the second liquid guiding portion <NUM> itself.

In some embodiments, the second liquid guiding portion <NUM> may be made of dense ceramic, and the second liquid guiding channels <NUM> may be liquid guiding holes formed on the second liquid guiding portion <NUM>, the liquid guiding holes are in communication with the first liquid guiding channel <NUM>.

In some embodiments, the third liquid guiding portion <NUM> may be the part of the atomization core <NUM>, that is, the part of the atomization core <NUM> extends toward the second liquid guiding portion <NUM> and abuts against the sidewall of the second liquid guiding portion <NUM>, and the micro pores on the atomization core <NUM> form the third liquid guiding channel <NUM>.

In some embodiments, the other end of the third liquid guiding channel <NUM> is in communication with the atomization core <NUM>, and the capillary force of the third liquid guiding channel <NUM> is smaller than the capillary force of the atomization core <NUM>, so as to guide the liquid on the bottom plate 11a to the atomization core <NUM> through the first liquid guiding channel <NUM>, the second liquid guiding channel <NUM>, and the third liquid guiding channel <NUM>, thereby enabling the liquid on the surface of the bottom plate 11a to reflux to increase the liquid utilization.

In some embodiments, one end of each third liquid guiding channel <NUM> on the third liquid guiding portion <NUM> away from the second liquid guiding channel <NUM> is in communication with the vertical groove to realize communication with the atomization core <NUM> through the vertical groove. In other embodiments, the one end of each third liquid guiding channel <NUM> away from the second liquid guiding channel <NUM> may also be an open end, a part of the atomization core <NUM> extends in the direction toward the bottom plate 11a and abuts against the sidewall of the third liquid guiding portion <NUM> away from the second liquid guiding portion <NUM>, thereby realizing communication between the third liquid guiding channels <NUM> and the atomization core <NUM>.

In some embodiments, one end of each third liquid guiding channel <NUM> is in communication with a second liquid guiding channel <NUM> at the edge of the second liquid guiding portion <NUM>.

In some embodiments, the third liquid guiding channel <NUM> may also be a liquid guiding groove or a liquid guiding hole, which is not limited in this embodiment.

Still referring to <FIG>, in this embodiment, the liquid guiding assembly 141b includes a fourth liquid guiding portion <NUM>, the fourth liquid guiding portion <NUM> and the second liquid guiding portion <NUM> are symmetrically arranged on the two sides of the boss <NUM>, that is, symmetrically arranged on the two sides of the air inlet holes <NUM> and on two opposite sides of the first liquid guiding portion <NUM>. In some embodiments, the fourth liquid guiding portion <NUM> has at least one fourth liquid guiding channel <NUM>, and one end of the fourth liquid guiding channel <NUM> is in communication with the first surface of the bottom plate 11a for guiding the liquid on the bottom plate 11a to the fourth liquid guiding portion <NUM> to store the liquid by the fourth liquid guiding portion <NUM>.

In some embodiments, the structure and a function of the fourth liquid guiding portion <NUM> are the same as or similar to the structure and a function of the second liquid guiding portion <NUM>, and the same or similar technical effects may be achieved. For details, reference may be made to the foregoing relevant written records, which are not described herein again.

In some embodiments, in this embodiment, the atomization core <NUM> is arranged on ends of the second liquid guiding portion <NUM> and the fourth liquid guiding portion <NUM> away from the bottom plate 11a, and abuts against the second liquid guiding portion <NUM> and the fourth liquid guiding portion <NUM>. In this way, the second liquid guiding portion <NUM> and the fourth liquid guiding portion <NUM> provide certain support to the atomization core <NUM>, and in addition, liquid passing through the second liquid guiding portion <NUM> and/or the fourth liquid guiding portion <NUM> may reflux to the atomization core <NUM>. It may be understood that in other embodiments, the fourth liquid guiding portion <NUM> may be also not defined on any fourth guiding channel <NUM> and only provides certain support to the atomization core <NUM>.

The capillary force of the fourth liquid guiding channel <NUM> is greater than the capillary force of the fifth liquid guiding channel <NUM>, so that liquid absorbed by the fifth liquid guiding portion <NUM> by the capillary force of the fifth liquid guiding channel <NUM> is guided to the fourth liquid guiding portion <NUM>. In some embodiments, the structure and a function of the fifth liquid guiding portion <NUM> are the same as or similar to the structure and a function of the first liquid guiding portion <NUM>, and the same or similar technical effects may be achieved. For details, reference may be made to the foregoing relevant written records, which are not described herein again. In some embodiments, the fifth liquid guiding portion <NUM> is arranged between the second liquid guiding portion <NUM> and the fourth liquid guiding portion <NUM>, and in some embodiments, the fifth liquid guiding portion <NUM> and the first liquid guiding portion <NUM> are symmetrically arranged on the two sides of the boss <NUM>, that is, symmetrically arranged on the two sides of the air inlet holes <NUM>. It may be understood that the transverse dimension of the fifth liquid guiding channel <NUM> gradually decreases in the direction toward the fourth liquid guiding channel <NUM> to absorb and guide the liquid on the first surface of the bottom plate 11a, so that the liquid on the first surface of the bottom plate 11a may reflux to the atomization core <NUM> through the fifth liquid guiding channel <NUM> and fourth liquid guiding channel <NUM> to increase a reflux volume and the reflux efficiency of the liquid on the first surface of the bottom plate 11a.

In this way, the capillary force of the first liquid guiding channel <NUM> increases gradually in the direction toward the second liquid guiding portion <NUM>, and the gradually increasing capillary force is used to absorb and guide the liquid on the first surface of the bottom plate 11a; and moreover, the capillary force of the second liquid guiding channel <NUM> is greater than the capillary force of the first liquid guiding channel <NUM>, so that the liquid absorbed by the first liquid guiding portion <NUM> by the capillary force of the first liquid guiding channel <NUM> is guided to the second liquid guiding portion <NUM>. Therefore, the liquid on the bottom plate 11a is stored to greatly reduce the probability of liquid leakage of the atomizer <NUM>.

Still referring to <FIG>, in this embodiment, a liquid guiding structure <NUM> is provided. The liquid guiding structure <NUM> includes a base 141a and a liquid guiding assembly 141b arranged on the base 141a. The base 141a has a first surface and a second surface that are arranged opposite to each other, and the liquid guiding assembly 141b is arranged on the first surface of the base 141a for absorbing liquid on the base 141a.

In an embodiment, the liquid guiding structure <NUM> may be directly applied to the atomizer <NUM> to absorb and guide liquid accumulated in the atomizer cavity <NUM>, thereby greatly reducing the probability of liquid leakage. In some embodiments, in this embodiment, the base 141a in the liquid guiding structure <NUM> may be directly used as the bottom plate 11a in the atomizer <NUM> of the foregoing embodiment, that is, the base 141a of the liquid guiding structure <NUM> forms the bottom plate 11a of the atomizer cavity. In this embodiment, the structure and a function of the base 141a are the same as or similar to the structure and a function of the bottom plate 11a in the atomizer <NUM> provided in the foregoing embodiment, and the same or similar technical effects may be achieved. For details, reference may be made to the foregoing text description, which are not described herein again.

In other embodiments, the liquid guiding structure <NUM> may also be directly arranged on the bottom plate 11a of the atomizer <NUM>. In some embodiments, a groove extending toward the second surface may be defined on the first surface of the bottom plate 11a of the atomizer <NUM>, the base 141a of the liquid guiding structure <NUM> is arranged in the groove, and the first surface of the base 141a is flush with the first surface of the bottom plate 11a of the atomizer <NUM>, so that the liquid on the first surface of the bottom plate 11a may flow to the first surface of the base 141a, and the liquid guiding assembly 141b may absorb and guide the liquid on the first surface of the bottom plate 11a. It may be understood that in this embodiment, the boss <NUM> is formed on the base 141a and a through hole in communication with the air inlet holes <NUM> is formed on the base 141a to communicate the atomization cavity <NUM> with external air.

The structure and a function of the liquid guiding assembly 141b are the same as or similar to the structure and a function of the liquid guiding assembly 141b in the atomizer <NUM> provided in the foregoing embodiment, and the same or similar technical effects may be achieved. For details, reference may be made to the foregoing text description, which are not described herein again.

According to the liquid guiding structure <NUM> provided in this embodiment, by arranging the base 141a and arranging the first liquid guiding portion <NUM> on the first surface of the base 141a, the first liquid guiding portion <NUM> cooperates with the first surface of the base 141a to form at least one first liquid guiding channel <NUM>. In addition, the second liquid guiding portion <NUM> is arranged on the first surface of the base 141a, at least one second liquid guiding channel <NUM> is defined on the second liquid guiding portion <NUM>, one end of the second liquid guiding channel <NUM> is in communication with the first liquid guiding channel <NUM>, and the other end is configured to be in communication with the atomization core <NUM>. In this way, the liquid on the first surface of the base 141a may reflux to the atomization core <NUM> through the first liquid guiding channel <NUM> and the second liquid guiding channel <NUM>. In addition, the transverse dimension of the first liquid guiding channel <NUM> gradually decreases in the direction toward the second liquid guiding portion <NUM>, so that the capillary force of the first liquid guiding channel <NUM> increases in the direction toward the second liquid guiding portion <NUM> and the gradually increasing capillary force is used to absorb and guide the liquid on the first surface of the base 141a. In this way, the liquid on the first surface of the base 141a may flow into the first liquid guiding channel <NUM>, and reflux to the atomization core <NUM> through the second liquid guiding channel <NUM> in communication with the first liquid guiding channel <NUM>. Compared with the related art, not only the probability of liquid leakage is greatly reduced, but also the reflux volume and reflux efficiency of the liquid are effectively increased by using the gradually increasing capillary force of the liquid guiding channel to absorb and guide the liquid on the surface of the base 141a.
