Referring to fig. 1, fig. 1 is a schematic diagram illustrating an internal structure of an electronic atomization device 1000 according to some embodiments of the utility model. The electronic atomizing device 1000 includes an atomizer 200 and a power supply assembly 300, the power supply assembly 300 for supplying electric power to the atomizer 200.

Referring to fig. 1, in some embodiments of the present utility model, the atomizer 200 comprises a storage bin 230, the storage bin 230 having a storage chamber 231 for storing a liquid aerosol-generating substrate and a central passage 232 communicating with the outside.

Fig. 5 is a schematic structural view of the first housing 10 in some embodiments, fig. 6 is an assembled schematic structural view of the first housing 10 and the second housing 20 in some embodiments, and fig. 7 is another azimuth view of the structure shown in fig. 6. The air intake structure 100 provided in the embodiment of the present utility model will be described in detail with reference to fig. 5 to 7.

Referring to fig. 5, fig. 6, and fig. 7, an air intake structure 100 according to some embodiments of the present utility model includes an air intercepting passage b and at least two silencing cavities a, the air intercepting passage b is located on an airflow path, the at least two silencing cavities a are sequentially communicated along the airflow path, and the air intercepting passage b is directly communicated with at least one silencing cavity a.

The air interception channel b is a narrow channel with smaller flow area in the air inlet structure, and when the air flow passes through the air interception channel b, the air flow speed is higher to generate noise. The silencing cavity a is a hollow cavity structure, when the rapid air flow flowing out of the air intercepting channel b enters the silencing cavity a, the air flow is depressurized faster due to the large space volume of the silencing cavity a, and the strength of the sound wave generated by the air flow is gradually weakened under the continuous reflection of the inner wall of the silencing cavity a, so that the purposes of noise reduction and silencing are achieved. Meanwhile, when the sound-deadening chamber a is positioned at the upstream of the air-intercepting passage b, under the reflection of the sound-deadening chamber a at the downstream of the air-intercepting passage b, part of sound waves can be transmitted to the upstream sound-deadening chamber a and play a role in noise reduction and sound attenuation, and meanwhile, before the sound waves enter the air-intercepting passage b from the upstream sound-deadening chamber a, the sound waves also flow to the air-intercepting passage b after noise reduction and sound attenuation treatment is carried out on the sound waves to a certain degree. That is, the sound deadening chamber a communicating with the air intercepting duct b can perform a certain sound deadening effect on the air flow path, whether directly connected upstream or downstream of the air intercepting duct b. For the specific silencing principle of the silencing cavity a, reference may be made to the helmholtz silencing principle, which is not described in detail herein.

Wherein the number of the air intercepting passages b can be configured with one or more, each air intercepting passage b is directly communicated with at least one silencing cavity a, and each air intercepting passage b is directly communicated with one or more silencing cavities a. In general, when each of the cutoff passages b is directly communicated between the adjacent two of the sound deadening chambers a, the number of the sound deadening chambers a to which it is communicated is maximized. In practical application, each gas interception channel can directly select any one of the silencing cavities a to be directly communicated, and can be positioned at the upstream or downstream of the directly communicated silencing cavity a.

It is understood that two adjacent and communicating silencing chambers a on the airflow path are communicated through a communication channel, and the communication channel may or may not be the air intercepting channel b. When the communication channel is used as the air intercepting channel b, the flow area of the communication channel is equivalent to that of the air intercepting channel b, and when the communication channel is not used as the air intercepting channel b, the flow area of the communication channel is larger than that of the air intercepting channel b. It should be noted that the flow area of the communication passage and the cutoff passage b means the smallest cross-sectional area in the direction perpendicular to the flow direction of the air flow. The cross-sectional areas of the air interception channel b and the communication channel can be kept unchanged or changed along the air flow direction, and the air interception channel is not limited.

When the air intake structure 100 is applied to the air flow path of the electronic atomizing device 1000, the air flow path may be located either downstream of the atomizing space Q or upstream of the atomizing space Q, and may be provided in a narrow passage with a small flow area in the air flow path, and the specific position is not limited.

When the air inlet structure 100 is applied to the electronic atomization device 1000, the air inlet structure is positioned on the air flow path of the electronic atomization device 1000, and the air flow passes through the air interception channel b, so that noise is reduced under the action of the noise reduction cavity a communicated with the air interception channel, and the air flow noise generated by the excessively high air flow speed when the air flow passes through the air interception channel b can be greatly reduced, and the user experience is improved. Moreover, the air interception channel b can carry out noise reduction and noise reduction treatment through at least two noise reduction cavities a, and the noise reduction and noise reduction effect is good.

In some embodiments, referring to fig. 5 and 6, at least one of the at least two sound deadening chambers a located upstream of the first sound deadening chamber a and downstream of the last sound deadening chamber a is directly connected to the gas intercepting passageway b. Or, two adjacent silencing cavities a on the airflow path are communicated with each other through an air intercepting channel b.

The first silencing chamber a refers to the most upstream silencing chamber a of all silencing chambers a. The sound deadening chamber a located at the last position refers to the sound deadening chamber a located at the most downstream of all sound deadening chambers a. The arrangement mode of each air interception channel b can be directly communicated with the upstream of the first silencing cavity a, can be directly communicated with the downstream of the last silencing cavity a, and can be directly communicated between the two silencing cavities a. Of course, the upstream and/or downstream of the same sound-deadening chamber a should each have only one air-intercepting duct b in direct communication therewith.

Taking the air inlet structure 100 including two silencing cavities a, namely, a first silencing cavity a1 (located at the first position) and a second silencing cavity a2 (located at the last position), the arrangement mode of the air intercepting passageway b includes the following modes:

in the first arrangement, the air-intercepting passage b is arranged with one, and the air-intercepting passage b is directly communicated with the upstream of the first silencing cavity a1, or the air-intercepting passage b is directly communicated with the downstream of the second silencing cavity a2, or the air-intercepting passage b is directly communicated between the first silencing cavity a1 and the second silencing cavity a 2;

the second arrangement mode is that two air-intercepting passages b are arranged, and the two air-intercepting passages b are respectively and directly communicated with the upstream of the first silencing cavity a1 and the downstream of the second silencing cavity a 2; or one of the two air intercepting passages b is directly communicated with the upstream of the second silencing cavity a1 or the downstream of the second silencing cavity a2, and the other air intercepting passage b is directly communicated between the first silencing cavity a1 and the second silencing cavity a 2;

in the third arrangement, three air intercepting passages b are provided, and one air intercepting passage b is arranged between the first silencing cavity a1, the second silencing cavity a2 and the first silencing cavity a1 and the second silencing cavity a 2.

It is understood that when the cutoff passages b include a plurality of cutoff passages, the flow area of each cutoff passage b is equivalent.

In the embodiment shown in fig. 5 and 6, an air intercepting duct b is arranged upstream of the first sound deadening chamber a1, between the first sound deadening chamber a1 and the second sound deadening chamber a 2.

When the air interception channel b is directly communicated with the downstream of the last silencing cavity a, each silencing cavity a positioned on the upstream of the air interception channel b can reduce noise and speed of air flow entering the air interception channel b, and when the air flow flows through the air interception channel b, the noise is smaller, so that a certain silencing effect is achieved. When the air interception channel b is directly communicated with the upstream of the first silencing cavity a, each silencing cavity a positioned at the downstream of the air interception channel b can reduce noise and speed of air flow flowing out of the air interception channel b, and a certain silencing effect is achieved. When the air intercepting channel b is directly communicated between the two silencing cavities a, the silencing cavity a positioned at the upstream of the air intercepting channel b and the silencing cavity a positioned at the downstream of the air intercepting channel b can have certain noise reduction and silencing effects.

In some embodiments, at least two air intercepting passages b are arranged, and along the air flow path, the air outflow direction of the upstream air intercepting passage b is the same as the air inflow direction of the downstream adjacent air intercepting passage b.

Continuing with the embodiment shown in fig. 5 as an example, in fig. 5, the air intercepting duct b includes two air intercepting ducts, namely, a first air intercepting duct b1 and a second air intercepting duct b2, wherein the first air intercepting duct b1 is directly communicated upstream of the first silencing cavity a1, and the second air intercepting duct b2 is communicated between the first silencing cavity a1 and the second silencing cavity a 2. In fig. 5, the air flow out direction of the first air intercepting duct b1 is the same as the air flow in direction of the second air intercepting duct b2 (both air flow directions are shown as reference sign F1 in fig. 5).

When the air flow out direction of the first air intercepting passage b1 is the same as the air flow in direction of the second air intercepting passage b2, each air intercepting passage b2 is more convenient to be formed.

In addition, the embodiment of the present utility model further provides an electronic atomization device 1000, which includes the air inlet structure 100 mentioned in any of the above embodiments, and the air inlet structure 100 is disposed on the air flow path of the electronic atomization device 1000, which includes all the above advantages and is not described herein.

As for the specific arrangement of the air intake structure 100, reference may be made to the following embodiments, in which the air intercepting groove 14 and the silencing groove 13 formed by the first housing 10 of the power supply assembly 300 are obtained in cooperation with the second housing 20 of the atomizer 200. In other embodiments, the atomizer 200 having the features of the first housing 10 may be combined with the power supply assembly 300 having the features of the second housing 20. Or the air intake structure 100 may be obtained by combining two other structures having the features of the first housing 10 and the second housing 20, respectively, the following embodiments are not limited to the arrangement of the air intake structure 100 in the electronic atomizing device 1000.

Next, a description will be given of a power supply assembly 300 provided in an embodiment of the present utility model.

When the power supply assembly 300 is coupled with the atomizer 200, the second housing 20 in the atomizer 200 covers the silencing groove 13 and the air intercepting groove 14 to form the silencing chamber a and the air intercepting passage b of the air intake structure 100 in any of the above embodiments.

The first housing 10 may be a plastic housing, and the structural end face 12 may be an end face thereof located in the longitudinal direction of the power supply assembly 300. It is understood that each sound deadening groove 13 is a groove provided in the structural end face 12, which groove is recessed substantially in the longitudinal direction, and whose notch is covered by the second housing 20 of the atomizer 200. The depth of the recess of each sound deadening groove 13 may be the same or different, and is not particularly limited.

In practical application, the first housing 10 is covered by the second housing 20 and the two housings are coupled, which may be clamped, fastened, magnetically connected, etc. The first casing 10 is coupled with the second casing 20, and the second casing 20 is directly covered on the structural end face 12 to cover the silencing groove 13 and the air intercepting groove 14 at the same time, and respectively obtain a silencing cavity a and an air intercepting channel b.

In order to ensure the tightness of the sound deadening chamber a and the gas shut-off passage b, the second housing 20 is connected in a sealing manner to the end face 12. Specifically, the second casing 20 may be a sealing material member and is directly in sealing connection with the structural end face 12, or a sealing structure may be provided at a position of the second casing 20 corresponding to each of the silencing grooves 13 and the air-blocking grooves 14 to realize sealing performance of the silencing chamber a and the air-blocking channel b, and a manner of realizing sealing connection between the second casing 20 and the structural end face 12 is not limited.

At this time, the silencing cavity a and the air intercepting passage b of the air intake structure 100 of the electronic atomizing device 1000 are formed by combining the silencing groove 13 and the air intercepting groove 14 processed on the first housing 10 with the second housing 20, and the silencing cavity a and the air intercepting passage b are simple to process and have low manufacturing cost. Meanwhile, the power module 300 has the advantages of the air intake structure 100 described above, which is not described herein.

Meanwhile, the first housing 10 and the second housing 20 may not only form the air intake structure 100, but also serve as a part of the power supply assembly 300 and the atomizer 200, so that the electronic atomization device 1000 is more compact in structure and avoids redundancy.

It is to be understood that in the embodiment shown in fig. 5 to 7, all the silencing chambers a are arranged in the same plane perpendicular to the air outlet direction F2 of the last silencing groove 13. At this time, the inner walls of the silencing chambers a are coplanar at least one end in the air outlet direction F2, so that in the actual construction, the silencing chambers a can be obtained by arranging the partition members on the shared plane, and the silencing chambers a are convenient to process.

In some embodiments, referring to fig. 5, the first housing 10 further has a rim end surface 15 and a concave wall surface 16, the rim end surface 15 is disposed around the structural end surface 12, the concave wall surface 16 is connected between the rim end surface 15 and the structural end surface 12 at an angle, the rim end surface 15 and the concave wall surface 16 are configured to form an air inlet channel c around the second housing 20, and the air inlet channel c is directly connected upstream of the at least two silencing cavities a.

The edge face 15 is offset from the structural face 12 in the longitudinal direction of the power supply assembly 300, i.e., the longitudinal height position of the edge face 15 differs from the structural face 12. The edge end surface 15 may be formed in a full circle around the structural end surface 12, may be formed in a half circle, or the like, that is, the length of the air inlet channel c is not limited.

The concave wall surface 16 has a certain distribution length in the longitudinal direction of the power supply assembly 300, and is connected to both the edge end surface 15 and the structural end surface 12 at an angle (may be perpendicular in particular), and it is understood that the concave wall surface 16 may be formed in a full circle, a half circle, or the like around the structural end surface 12, and the concave wall surface 16 is an outer wall surface.

The outside atmosphere enters the first-stage air intercepting channel b after passing through the air inlet groove c, and then flows along each stage of silencing cavities a, and at the moment, the air inlet mode of the air inlet structure 100 is simple, and the air inlet structure is easy to process and mold.

In some embodiments, an air-intercepting duct b is disposed through the concave wall 16 and is in direct communication upstream of the at least two sound-deadening chambers a.

That is, the inlet of the first air intercepting passageway b1 is disposed on the concave wall surface 16, so that the air flow enters the first air intercepting passageway b1 along the concave wall surface 16 when flowing in the air inlet groove c, the air inlet groove c is directly communicated with the first air intercepting passageway b1, an intermediate structure is not needed, the air inlet structure 100 is simpler, and the molding is more convenient.

The third casing 30 and the first casing 10 have a gap therebetween, and the gap communicates the air intake groove c with the atmosphere. The outside atmosphere enters the third housing 30 through the gap between the third housing 30 and the first housing 10, and then passes through the air inlet groove c, the air intercepting passage b and the silencing cavity a.

At this time, the communication between the air inlet groove c and the atmosphere is achieved by reserving a gap between the third casing 30 and the first casing 10, and the processing is simpler.

Of course, in other embodiments, an air inlet may be provided on the third housing 30, and air may be directly fed to the air inlet channel c through the air inlet, or in other ways, and those skilled in the art may flexibly set the air inlet, which is not limited herein.

In some embodiments, the first housing 10 and the second housing 20 are magnetically coupled. Specifically, the first magnetic part 11 (such as a permanent magnet) may be configured on the first housing 10, and the second housing 20 may be a metal part, and the first magnetic part 11 magnetically attracts the second housing 20 to achieve the mating of the two. The second magnetic part may be disposed on the second housing 20, and the first magnetic part 11 and the second magnetic part may be coupled to each other when magnetically attracted to each other, and the manner of specifically implementing the magnetic connection therebetween is not particularly limited.

At this time, the first casing 10 and the second casing 20 are connected via a magnetic attraction manner, and the assembly is simple and reliable.

In addition, the embodiment of the present utility model further provides an electronic atomization device 1000, which includes the atomizer 200 and the power supply assembly 300, wherein the second housing 20 of the atomizer 200 covers the silencing slot 13 and the air intercepting slot 14 of the first housing 10, and the electronic atomization device 1000 has all the above beneficial effects and is not described herein.

The second housing 20 may be formed by the atomizing housing 210, or may be another housing structure provided on the atomizing housing 210.

In some embodiments, the atomizer 200 has a flow opening K communicating with the last muffler slot 13, and the projected area of the flow opening K is smaller than the projected area of the last muffler slot 13 along the opening direction of the flow opening K.

In general, the flow port K communicates with the atomizing space Q of the atomizer 200, and the flow port K serves as a passage through which the air flows out of the muffler 13 and into the atomizing space Q. The opening direction of the flow port K is substantially along the longitudinal direction of the electronic atomizing device 1000.

The circulation port K is communicated with the last silencing groove 13, the projection area of the circulation port K is smaller than that of the last silencing groove 13 along the opening direction of the circulation port K, when the airflow flows out of the last silencing groove 13 into and out of the circulation port, the noise generated when the airflow passes through the circulation port is weaker under the silencing and noise reducing effects of the last silencing groove 13, namely, the last silencing groove 13 performs certain noise reducing treatment on the circulation port.

In other embodiments, the last silencing groove 13 may not be connected to the atomizing space Q through the flow port K. For example, the atomizing space Q and the last muffler tank 13 are communicated through a gap between the second housing 20 and the third housing 30.

In some embodiments, referring to fig. 1 and 7, the power supply assembly 300 further includes a power supply terminal 301, where the power supply terminal 301 sequentially penetrates through the sound-deadening chamber a at the last position and is electrically connected to the atomizer 200.

The power supply terminal 301 may be connected to a battery or a circuit board in the power supply assembly 300 through a wire to obtain electric power from the battery, and the power supply terminal 301 is docked with the power receiving terminal 251 of the heat generating member 250 to supply power to the heat generating member 250.

At this time, the power supply terminal 301 passes through the sound deadening chamber a at the last position, enters the atomizer 200, and is electrically connected to the power receiving terminal 251 of the heating element 250, thereby realizing power supply. Meanwhile, the power supply terminal 301 is installed through the channel structure of the silencing cavity a, other installation channels do not need to be machined, and the structure of the electronic atomization device 1000 is more compact. In addition, the surface of the portion of the power supply terminal 301 passing through the final sound deadening chamber a can be used to reflect sound waves, which corresponds to an increase in the inner surface area of the final sound deadening chamber a, enabling enhancement of the noise reduction effect.

Further, the power supply terminal 301 has an elastic structure to be tightly abutted with the power connection terminal 251 of the heat generating member 250. Specifically, the power supply terminal 301 may have a spring and a tip provided at an end of the spring facing the power receiving terminal 251. Further, the end is in concave-convex fit with the electric terminal 251, so that the combination is more reliable, and the electric transmission is more stable.

Further, referring to fig. 7, after the power supply terminal 301 passes through the final silencing cavity a, it enters the atomizing space Q through the flow port K and is electrically connected to the atomizer 200. In other embodiments, the silencing chamber a through which the power supply terminal 301 passes may be electrically connected to the atomizer 200 without passing through the flow port K.

In the air inlet structure 100, the power supply assembly 300 and the electronic atomization device 1000 provided by the embodiment of the utility model, on the air flow path of the electronic atomization device 1000, air flow enters a silencing cavity a for noise reduction and silencing every time the air flow passes through one air interception channel b, so that air flow noise generated by too high air flow speed when the air flow passes through the air interception channel b can be greatly reduced, and user experience is improved. Furthermore, the noise reduction and silencing treatment of the silencing cavity a with at least two layers has good noise reduction and silencing effects.
