The base 23 is matched to an end of the housing side wall 214 away from the housing top wall 212 to close the open end of the main housing 21 . It can be understood that the shape of the housing 20 is not limited thereto, and can be set in different shapes as required to meet different requirements.

In the following embodiments, the longitudinal direction is defined as the height direction of the housing 20 (i.e. the Z direction in FIG. 2), the first transverse direction is the length direction of the main housing 21 (i.e. the X direction in FIG. 2), and the second transverse direction is the main direction.

In combination with Figure 5 and Figure 6, Figure 5 shows an exploded schematic view of the atomizer in an embodiment of the present application, and Figure 6 shows the structure of the atomization top cover of the atomizer in an embodiment of the present application schematic diagram.

In this specific embodiment, the atomization assembly 40 is fitted in the main casing 21 and is located at one end close to the base 23 in the longitudinal direction. Since the main casing 21 is a hollow columnar structure with one end open, when the atomizing assembly 40 is fitted in the main casing 21, the main casing 21 and the atomizing assembly 40 jointly define and form a reservoir for storing the aerosol generating substrate. Liquid chamber 25. It can be understood that, in some other embodiments, the liquid storage chamber 25 itself is a closed structure formed in the main housing 21 capable of storing the aerosol-generating substrate, and it does not need to be blocked by the mating of the atomizing component 40 , it is only necessary to realize that the liquid storage chamber 25 can be used to store the aerosol generating substrate, which is not limited here.

Specifically, the atomization assembly 40 includes an atomization seat 41 having an atomization cavity and an atomization core 43 accommodated in the atomization cavity. Wherein, the atomizing seat 41 is provided with at least one lower liquid port 4142a and at least one air outlet 4142b, and the lower liquid port 4142a is used for the aerosol generating substrate to flow from the liquid storage chamber 25 to the atomizing core 43 in the atomizing chamber. The air outlet 4142b communicates with the atomization chamber and the air outlet 27, and is used for the aerosol generated by the atomization core 43 to flow out from the atomization chamber into the air outlet 27 for inhalation by the user.

In this application, the lower liquid port 4142a is located on the side of the atomization seat 41 away from the air outlet channel 27 and directly below the liquid storage chamber 25, and the air outlet 4142b is located on the other side of the atomization seat 41 near the air outlet channel 27 and is located in the storage chamber. One side of the liquid chamber 25 in the first transverse direction.

In this way, the lower liquid port 4142a and the air outlet 4142b are respectively located on both sides of the atomizing seat 41 in the first transverse direction, so the aerosol flowing out from the air outlet 4142b can quickly enter the air outlet channel 27 on this side without passing through the lower liquid port 4142a, thereby avoiding the interference between the lower liquid port 4142a and the air outlet 4142b, causing the aerosol generating matrix to leak through the air outlet 4142b, and at the same time, the aerosol flowing out of the air outlet 4142b can quickly enter the air outlet 4142b, reducing the aerosol flow resistance along the way.

In some embodiments, the atomizing top cover 414 defines a lower liquid port 4142a and two air outlets 4142b. The port 4142a is located on the side of the two air outlets 4142b away from the air outlet channel 27, and in the second transverse direction, the two air outlets 4142b are respectively located on both sides of the lower liquid port 4142a.

Therefore, the aerosol in the atomization chamber respectively flows out through the two air outlets 4142b and converges into the air outlet 27 . Compared with only one air outlet 4142b, the aerosol can be fully released through the two air outlets 4142b, thereby increasing the air output of the air outlet 27.

The atomization seat 41 includes an atomization base 412, an atomization top cover 414, and a top cover seal 416. The atomization base 412 and the atomization top cover 414 are interlocked to form an atomization cavity for accommodating the atomization core 43. The cover seal 416 is disposed on an end of the atomizing top cover 414 away from the atomizing base 412 to seal the gap between the shell 20 and the atomizing top cover 414 .

Specifically, the atomizing base 412 has a shell structure, including a bottom wall of the base and a side wall of the base extending from the edge of the bottom wall of the base in the same direction. The side wall of the base surrounds the bottom wall of the base in a circumferential direction to form a base with an open end The accommodating cavity 4121 and the side wall of the base define a holding groove 4123 for mating with the atomizing top cover 414 .

The atomizing top cover 414 has a shell structure, including a top cover top wall 4141 and a top cover side wall 4144 extending from the edge of the top cover top wall 4141 in the same direction. The top cover side wall 4144 is far away from the end of the top cover top wall 4141 Inserted in the base accommodation cavity 4121 of the atomization base 412, the side wall 4144 of the top cover inserted into the base accommodation cavity 4121 is provided with a connecting buckle 4145 at one end, and the connecting buckle 4145 is clamped on the clamping opening on the side wall of the base slot 4123. Both the lower liquid port 4142a and the gas outlet port 4142b are opened at one end of the atomizing top cover 414 protruding from the base accommodating cavity 4121 .

The top cover seal 416 is formed by a certain elastic material such as silica gel, and includes a sealing top wall and a sealing side wall surrounding the sealing top wall in the circumferential direction, and the sealing top wall covers the outer surface of the top cover top wall 4141 of the atomizing top cover 414 , the sealing side wall surrounds the side wall 4144 of the top cover and connects one side of the top wall 4141 of the top cover in the circumferential direction. When the atomization assembly 40 is connected to one end of the housing 20, the top sealing wall of the top cover seal 416 is in contact with the liquid storage chamber 25 on the side surface away from the atomization top cover 414, and the sealing side wall of the top cover seal 416 can be The gap between the atomizing top cover 414 and the housing 20 is sealed.

In some embodiments, the liquid inlet end of the lower liquid port 4142a and the gas outlet end of the air outlet port 4142b are respectively formed on different planes arranged at intervals in the longitudinal direction of the atomization seat 41, so as to be staggered in the longitudinal direction of the atomization seat 41 . In this way, since the liquid inlet end of the lower liquid port 4142a and the gas outlet end of the air outlet port 4142b are located on different planes of the atomizing seat 41 and there is a certain height difference in the longitudinal direction, it can prevent the liquid from entering the atomizing seat 41 through the lower liquid port 4142a The aerosol-generating substrate interferes with the aerosol flowing out of the atomizing seat 41 through the air outlet 4142b, thereby preventing the aerosol-generating substrate from leaking through the air outlet 4142b.

Specifically, the top wall 4141 of the atomizing top cover 414 has a first end surface 4142 and a second end surface 4143, the first end surface 4142 and the second end surface 4143 are spaced apart and arranged in parallel in the longitudinal direction, and the first end surface 4142 is opposite to the liquid storage The distance between the cavity 25 is smaller than the distance between the second end surface 4143 and the liquid storage cavity 25 . The liquid inlet end of the lower liquid port 4142a is formed on the first end surface 4142, the gas outlet end of the air outlet 4142b is formed on the second end surface 4143, the sealing top wall of the top cover seal 416 covers the first end surface 4142, and the sealing top wall runs through The lower liquid port 4142a is connected to the communication groove 4161 of the liquid storage chamber 25, and the shape of the communication groove 4161 matches the shape of the lower liquid port 4142a.

In this way, the liquid inlet end of the lower liquid port 4142a and the gas outlet end of the gas outlet port 4142b are located on different planes of the atomizing top cover 414 and there is a height difference in the longitudinal direction, the distance between the liquid inlet end of the lower liquid port 4142a and the liquid storage chamber 25 It is closer, so that the aerosol-generating substrate in the liquid storage chamber 25 can pass through the communication groove 4161 and enter the atomization chamber from the lower liquid port 4142a, effectively preventing the aerosol-generating substrate from flowing into the air outlet 4142b and leaking through the air outlet 4142b.

Further, the orthographic projection of the air outlet end of the air outlet 4142b on the plane of the first end surface 4142 is at least partly located on the first end surface 4142, preferably, the orthographic projection of the air outlet end of the air outlet 4142b on the plane of the first end surface 4142 is all Located on the first end surface 4142 . In this way, the first end surface 4142 blocks the opening of the liquid storage chamber 25 and shields the gas outlet of the gas outlet 4142b, effectively preventing the aerosol-forming substrate in the liquid storage chamber 25 from flowing into the gas outlet 4142b and leaking through the gas outlet 4142b.

The atomizing core 43 is a cuboid structure formed of ceramic material. The length of the atomizing core 43 in the first transverse direction is greater than its length in the second transverse direction, so the atomizing core 43 has longitudinal directions perpendicular to the atomizing seat 41 respectively. The length direction and width direction of the atomization core 43 extend along the first transverse direction, and the width direction of the atomization core 43 extends along the second transverse direction. A heating wire is attached to the surface of the atomizing core 43 away from the liquid storage chamber 25 . The atomization assembly 40 also includes a positive electrode 45 and a negative electrode 47, the positive electrode 45 and the negative electrode 47 are arranged at intervals in the first transverse direction, one end of the positive electrode 45 and one end of the negative electrode 47 are respectively connected to opposite ends of the heating wire, the positive The other end of the electrode 45 and the other end of the negative electrode 47 expose the atomizing base 412 for electrical connection with the power supply assembly. In this way, the power supply component supplies power to the heating wire through the positive electrode 45 and the negative electrode 47, and the heating wire after electrification heats the atomizing core 43, and the atomizing core 43 gradually heats up to heat the aerosol generating matrix to generate aerosol.

Further, along the length direction of the atomizing core 43, the atomizing core 43 is biasedly arranged in the atomizing seat 41, and the first end of the atomizing core 43 along the length direction is close to the air outlet 4142b of the atomizing seat 41. The second end of the 43 along the length direction is away from the air outlet 4142b of the atomization seat 41 , and the liquid inlet end of the lower liquid port 4142a is close to the second end of the atomization core 43 in the length direction. Along the width direction of the atomizing core 43, the atomizing core 43 is centrally arranged in the atomizing seat 41, that is, the distance between the atomizing core 43 and the walls on both sides of the atomizing chamber in the second transverse direction is equal, and the two air outlets 4142b are respectively located on opposite sides of the atomization core 43 along the width direction. In order to make the aerosol-generating substrate flow to the offset atomizing core 43, the liquid inlet end of the lower liquid port 4142a opened on the atomizing top cover 414 bends and extends from the first end surface 4142 toward the position of the atomizing core 43, thereby The aerosol-generating substrate is directed onto the atomizing wick 43 .

In this way, the atomizing core 43 is set on the side where the air outlet 4142b is located to adapt to the position of the air outlet 4142b, and the aerosol generated on the atomizing core 43 can quickly flow out from both sides of the atomizing core 43 through the air outlet 4142b, thereby shrinking The resistance along the course of the gas flow is ensured, and the gas output of the air outlet channel 27 is ensured.

In some embodiments, in the longitudinal direction, the plane where the air outlet end of the air outlet 4142b is located (that is, the second end surface 4143 ) is higher than the top surface of the atomizing core 43 facing the lower liquid port 4142a, so that the air on the atomizing core 43 is avoided. The sol-generating matrix flows out from the gas outlet 4142b. Moreover, since there is a certain distance between the atomizing core 43 and the top wall 4144 of the atomizing top cover 414 , the top wall 4144 of the top cover can be prevented from being melted or deformed by the heat generated by the atomizing core 43 during the atomization process. It can be understood that the specific distance between the atomizing core 43 and the top wall 4144 of the top cover is not limited, and can be set according to needs to meet different requirements.

In some embodiments, the atomizing top cover 414 defines a ventilation channel 4147, one end of the ventilation channel 4147 is connected to the lower liquid port 4142a, and the other end of the ventilation channel 4147 is connected to the side wall of the atomizing top cover 414 to communicate with the outside atmosphere. Therefore, the liquid storage chamber 25 communicates with the outside atmosphere through the ventilation channel 4147 , so as to avoid the consumption of the aerosol-generating substrate in the liquid storage chamber 25 and the formation of negative pressure, resulting in poor drainage.

Specifically, the atomizing top cover 414 defines two air exchange channels 4147, and the two air exchange channels 4147 are respectively located on both sides of the lower liquid port 4142a and arranged symmetrically. Each air exchange channel 4147 includes a first air exchange section, a second air exchange section and a third air exchange section connected in sequence. The first air exchange section is set on the side wall of the lower liquid port 4142a and extends longitudinally; The air section is set on the first end surface 4142 of the atomizing top cover 414 provided with the lower liquid port 4142a and extends in a zigzag manner, thereby increasing the length of the ventilation channel 4147; the third ventilation section is set on the atomizing top cover 414 close to the liquid storage chamber 25 The side wall at one end and extends longitudinally.

It can be understood that the number of ventilation channels 4147 and the direction of extension of the ventilation channels 4147 are not limited, and can be set according to the shape of the atomizing top cover 414 and different ventilation requirements.

In some embodiments, at least one liquid storage tank 4146 extending in the circumferential direction is defined on the side wall of the end of the atomization seat 41 protruding from the base accommodation cavity 4121. The outflowing aerosol-generating substrate is absorbed and stored to prevent the aerosol-generating substrate from leaking out of the atomizer 100 to affect user experience and even damage battery components. Specifically, the atomizing seat 41 defines a plurality of liquid storage tanks 4146, and the plurality of liquid storage tanks 4146 are arranged at intervals along the longitudinal direction. It can be understood that the number and extension direction of the liquid storage tanks 4146 are not limited, and can be set according to needs to meet different requirements.

Moreover, the aerosol in the atomizing chamber can enter the air outlet 27 through the two air outlets 4142b located on both sides of the atomizing core 43, so that the aerosol in the atomizing chamber can be fully released, ensuring the stability of the atomizer 100.
