An embodiment of the present application provides a nebulizer, referring to fig. 1, 2 and 4, comprising a housing assembly 10 and a atomizing assembly 20, the housing assembly 10 having an air outlet 10a. The atomizing assembly 20 is arranged in the shell assembly 10, the atomizing assembly 20 comprises an atomizing cavity 20a and a liquid storage cavity 20b, the liquid storage cavity 20b is located on the periphery of the atomizing cavity 20a, an air inlet 221b is formed in the side wall of the atomizing cavity 20a, an air flow path passing through the atomizing cavity 20a is formed between the air inlet 221b and the air outlet 10a, a flow guide surface 221a is formed in the side wall of the atomizing cavity 20a, provided with the air inlet 221b, and the flow guide surface 221a forms a flow guide path connecting the atomizing cavity 20a with the liquid storage cavity 20 b.

Specifically, during user inhalation, ambient air flows into the atomizing assembly 20 from the air inlet 10a, flows through the atomizing chamber 20a along the air flow path, and flows out of the air outlet 10 a. Aerosol formed by the atomizing assembly 20 heating the atomized liquid can flow with the airflow for inhalation by the user.

Wherein an aerosol may be generated in the atomizing chamber 20a, such as an atomizing assembly 20 including an atomizing core 23 disposed within the atomizing chamber 20a, and heating the atomizing liquid through the atomizing core 23 to generate an aerosol in the atomizing chamber 20a to flow with the air stream.

The liquid storage chamber 20b may be used to store the liquid product from the atomizing chamber 20a, and the liquid storage chamber 20b is located at the peripheral side of the atomizing chamber 20a, which is not in the air flow path, so that the liquid product stored in the liquid storage chamber 20b does not flow with the air flow to flow out from the air outlet 10 a.

The flow guiding surface 221a has the function of guiding the effusion to flow, and the effusion in the atomizing chamber 20a can flow along the flow guiding surface 221a and flow into the liquid storage chamber 20b, so that the effusion is collected, for example, the effusion flows along the flow guiding surface 221a under the action of gravity.

For example, in the use state in which the air outlet 10a is upward, the accumulated liquid formed in the atomizing chamber 20a flows along the flow guiding surface 221a under the action of gravity, and flows into the liquid storage chamber 20 b.

According to practical situations, the flow guiding surface 221a may be located in the atomizing chamber 20a only in a partial area, or may be located in the atomizing chamber 20a in all areas, or may be connected to the edge of the atomizing chamber 20 a. Another embodiment of the present application provides an electronic atomization device, including an atomizer according to any of the embodiments of the present application.

The atomizer of the embodiment of the application comprises a shell assembly 10 and an atomization assembly 20, wherein the atomization assembly 20 is provided with an atomization cavity 20a and a liquid storage cavity 20b, the liquid storage cavity 20b is positioned on the periphery of the atomization cavity 20a, an air inlet 221b is formed in the side wall of the atomization cavity 20a, an air flow path passing through the atomization cavity 20a is formed between the air inlet 221b and the air outlet 10a, a flow guide surface 221a is formed in the side wall of the atomization cavity 20a, provided with the air inlet 221b, and the flow guide surface 221a forms a flow guide path connecting the atomization cavity 20a and the liquid storage cavity 20 b. Thus, the flow guide surface 221a can guide the liquid product generated in the atomizing chamber 20a to the liquid storage chamber 20b for collection without accumulation of the liquid product in the atomizing chamber 20 a. Therefore, when the airflow flowing along the airflow path flows through the atomizing cavity 20a, the accumulated liquid is not splashed by the accumulated airflow and flows out of the air outlet, so that gurgling sound is not generated, and the experience of a user can be improved.

In an embodiment, referring to fig. 2 and 8, the atomizing assembly 20 includes a first atomizing base 21 and a second atomizing base 22, the second atomizing base 22 is located on a side of the first atomizing base 21 facing away from the air outlet 10a, the first atomizing base 21 and the second atomizing base 22 together define an atomizing chamber 20a and a liquid storage chamber 20b, and a partial area of the second atomizing base 22 located on the side of the atomizing chamber 20a protrudes to form a boss 221 having a flow guiding surface 221 a.

Specifically, the atomizing chamber 20a and the liquid storage chamber 20b are each formed by being surrounded by a first atomizing base 21 and a second atomizing base 22. The partial area of the second atomizing base 22 near the atomizing chamber 20a protrudes to form a boss 221, and the boss 221 has a flow guiding surface 221a.

The first atomization seat 21 and the second atomization seat 22 may be integrally formed, or may be a split structure.

The specific location of the air inlet 221b is not limited, for example, referring to fig. 2, the air inlet 221b is located on the boss 221, and the sidewall of the air inlet 221b extends toward the inside of the atomizing chamber 20 a.

Specifically, the air inlet 221b is disposed on the boss 221, and the sidewall at the air inlet 221b extends into the atomizing chamber 20a, so that the sidewall at the air inlet 221b forms a height difference with the side surface of the boss 221, and the effusion flowing along the flow guiding surface 221a of the boss 221 can be prevented from flowing into the air inlet 221b, thereby preventing the effusion from flowing with the air flow.

It should be noted that the specific value of the height difference between the side wall of the air inlet 221b and the side surface of the boss 221 may be set according to the actual situation, for example, the height difference between the side wall of the air inlet 221b and the side surface of the boss 221 is greater than 0 and not greater than 4mm, such as 2mm or 4mm.

Of course, the air inlet 221b may also be provided at a side wall or other location of the atomizing chamber 20a, depending on the circumstances.

In addition, the flow guiding surface 221a may be formed in other manners. For example, the second atomizing base 22 is provided with an inclined slope on one side of the atomizing chamber 20a, so that the accumulated liquid in the atomizing chamber 20a can flow into the liquid storage chamber 20b under the flow guiding of the inclined slope after flowing onto the inclined slope under the action of gravity.

In one embodiment, referring to fig. 2, the first atomizing base 21 includes a wall 211 defining an airflow channel 21a, where the wall 211 and the boss 221 are spaced apart to form a space therebetween, one end of the airflow channel 21a is communicated with the air outlet 10a, the other end of the airflow channel 21a is communicated with the space, and the airflow channel 21a and the space together form at least a part of the atomizing chamber 20 a.

Specifically, the end of the wall body 211 facing away from the air outlet is spaced from the boss 221, and the first atomization seat 21 can be prevented from blocking the flow of the effusion along the flow guiding surface 221a by forming a space therebetween, so that the effusion can flow along the flow guiding path and flow into the liquid storage cavity 20b conveniently.

The air flow passage 21a is located on the air flow path for the air flow. In effect, the atomizing core 23 of the atomizing assembly 20 forms an aerosol by atomizing the atomized liquid such that the aerosol can flow with the air flow in the air flow channel 21a and out of the air outlet 10 a.

One end of the air flow passage 21a communicates with the air outlet 10a, the other end of the air flow passage 21a communicates with the space, and the air flow passage 21a and the space may together form the atomizing chamber 20a, but may be only a part of the atomizing chamber 20 a.

It should be noted that the specific size of the space may be determined according to practical situations. For example, the height of the space in the up-down direction is greater than 0mm and not greater than 4mm, such as 2mm or 4mm.

In one embodiment, along the gravity direction, the bottom surface of the atomizing chamber 20a is a guiding surface 221a.

That is, the flow guiding surface 221a of the boss 221 covers the entire area of the bottom side of the atomizing chamber 20 a. Thereby, the accumulated liquid in the air flow channel 21a can flow onto the boss 221 as much as possible to be guided into the liquid storage cavity 20b under the action of the guiding surface 221a of the boss 221. Meanwhile, in the sucking process, the generation of vortex of aerosol caused by diffusion to one side of the atomizing cavity 20a away from the air outlet 10a can be avoided, so that the air flow flowing along the air flow path is smoother, the sucking is more fragrant and sweet, and the sucking taste is improved.

The specific area of the flow guiding surface 221a may be set according to actual conditions. For example, the outer edge of the flow guiding surface 221a extends all over 0 to 4mm, such as 2mm or 4mm, outside the nebulizing chamber 20 a.

In addition, the specific shape and structural dimensions of the boss 221 may be set according to practical situations.

For example, the height of the boss 221 in the up-down direction is 0.3 to 8mm, such as 0.3mm, or 4mm, or 8mm.

As another example, the boss 221 may have an area of 10-120 mm ², such as 10mm ² or 60mm ² or 120mm ².

For another example, the cross-sectional shape of the boss 221 in the up-down direction is an arc surface, a square shape, or a special shape.

In an embodiment, referring to fig. 3 to 7, the second atomizing base 22 includes a liquid storage frame 222 disposed in the liquid storage cavity 20b, and an outer surface of the liquid storage frame 222 has a liquid storage channel 222a.

It should be noted that, the liquid storage rack 222 is located in the liquid storage cavity 20b, and the liquid storage channel 222a can be used to adsorb and store the accumulated liquid flowing into the liquid storage cavity 20 b. Thus, no matter the atomizer is in the use state that the air outlet 10a faces upwards or in the inverted state that the air outlet 10a faces downwards, the accumulated liquid can be adsorbed and stored in the liquid storage channel 222a, and cannot leak out from the air outlet 10a due to backflow into the atomizing cavity 20 a.

The specific structure of the liquid storage passage 222a is not limited. The liquid storage channel 222a is a capillary groove, so that the liquid can flow along the liquid storage channel 222a under the action of capillary force, and can be stored in the liquid storage channel 222a more stably, so that the liquid cannot easily flow out of the liquid storage cavity 20 b.

It is understood that a capillary groove refers to a groove structure that is capable of generating a capillary phenomenon so that a liquid product can be stored in the groove by capillary force.

In one embodiment, referring to fig. 5-7, the reservoir 222 has a mounting cavity 222b, and the atomizer further includes a reservoir located within the mounting cavity 222 b.

Specifically, the liquid storage body is a structure capable of adsorbing and storing liquid accumulation, such as liquid-absorbing cotton. Therefore, more accumulated liquid can be adsorbed by the liquid storage body, and turbulent flow of the accumulated liquid caused by shaking of the atomizer is avoided.

The size of the liquid storage chamber 20b may be set according to practical situations, for example, the width of the liquid storage chamber 20b in the interval direction of the liquid storage frame 222 is 0.5 to 15mm, such as 0.5mm, 7.5mm, or 15mm.

As another example, the volume of the reservoir 20b is 0.5-5 ml, such as 0.5ml, 2.5ml, or 5ml.

In one embodiment, referring to fig. 5 to 7, the liquid storage rack 222 includes a plurality of partition boards 2221, each partition board 2221 is layered and spaced along the gravity direction to form a liquid storage tank 222c, and the liquid storage channel 222a includes a liquid storage tank 222c and a communication tank 222d communicating with the adjacent liquid storage tanks 222 c.

Specifically, the reservoir 222 is formed by a plurality of partitions 2221 layered and arranged at intervals. Through layering and interval setting, can avoid stock solution frame 222 to occupy the space in too much stock solution chamber 20b, can make the hydrops in the stock solution chamber 20b can be collected steadily.

The liquid storage grooves 222c are formed at intervals between two adjacent partition boards 2221, and a partial area of the partition board 2221 between two adjacent liquid storage grooves 222c is recessed to form the communication groove 222d.

In one embodiment, the liquid storage groove 222c and the communication groove 222d are capillary grooves. Accordingly, the liquid product can be stored in the liquid storage groove 222c and the communication groove 222d between the respective partition boards 2221 by the capillary force, and the liquid product can be adsorbed to prevent the flow of the liquid product.
