Referring to FIGS. 2 and 3 , the atomization base 23 includes a base 231 , and the base 231 and the support base 24 together form the atomization chamber 21 . The base body 231 has a bottom surface 2311 located away from the support base 24. The first air outlet 22 is opened on the bottom surface 2311 and penetrates the base body 231, so that the airflow chamber 30 and the atomization chamber 21 are connected. Referring to Figures 3 and 4, the atomizer base 23 also includes a silencing structure 232 provided in the airflow chamber 30. The silencing structure 232 is protruding on the bottom surface 2311 of the base 231 and is located where the airflow flows from the air inlet 11 to the first air outlet. 22 on the flow path.

Continuing to refer to FIG. 3 , an air inlet area 233 is formed on the base 231 , and the silencer structure 232 has a plurality of sub-air flow channels 2321 . The air inlet 11 , the air inlet area 233 , the sub-air flow channels 2321 and the first air outlet 22 are connected in sequence. The main airflow flowing out of the air inlet area 233 in all airflow channels 2321 is divided into several partial airflows and decelerated and discharged toward the first air outlet 22 . In this way, when the external airflow flows from the air inlet 11 to the air inlet area 233 and flows to the first air outlet 22 through the divided airflow channel 2321, the divided airflow channel 2321 formed by the silencer structure 232 will flow the air inlet area 233 to its divided airflow channel. The airflow is divided into several airflows and decelerated and discharged. The slower airflow generates less noise than the faster airflow, so the setting of the silencing structure 232 achieves the purpose of silencing and reducing noise.

The silencing structure 232 includes a plurality of first silencing blocks 2322 spaced apart in the first direction, and a branch airflow channel 2321 is formed between every two adjacent first silencing blocks 2322. Wherein, the first direction intersects the flow direction of the main airflow. This arrangement facilitates the formation of the divided airflow channels 2321 and facilitates the sound attenuation of the sound attenuating structure 232 .

Specifically, the first direction is perpendicular to the flow direction of the main airflow. Referring to Figure 1, the width direction of the atomizer 100 in Figure 1 is the flow direction of the main airflow, which is the left and right direction in Figure 1. The first direction is the thickness direction of the atomizer 100, which is perpendicular to the paper in Figure 1. direction of the face.

It should be noted here that in order to facilitate the flow of air flow, there is a gap between each first silencer block 2322 and the inner wall of the bottom case 14 .

The silencing structure 232 includes four first silencing blocks 2322 , and the four first silencing blocks 2322 are spaced apart in the first direction to form three divided airflow channels 2321 . It is conceivable that in other embodiments, the number of first silencing blocks 2322 included in the silencing structure 232 is not limited.

All the first muffler blocks 2322 are arranged at equal intervals in the first direction, so that the size of each partial airflow channel 2321 in the first direction is equal to ensure that the speed of the airflow flowing out of each partial airflow channel 2321 is equal. This avoids mutual interference between the airflows with different speeds and further improves the noise reduction effect. Of course, in other embodiments, the spacing between each two adjacent first silencing blocks 2322 may also be unequal, which is not limited here.

Each first muffler block 2322 is cylindrical and extends in a direction away from the bottom surface 2311 . In this way, the outer peripheral surfaces of each adjacent two first muffler blocks 2322 form branch airflow channels 2321, and the smooth outer peripheral surfaces utilize the flow of airflow to ensure smooth airflow. It should be understood that in other embodiments, the shape of the first silencing block 2322 is not specifically limited. For example, the first silencing block 2322 may also be in a prism shape or other irregular shape.

Further, continuing to refer to FIG. 3 , the atomizer base 23 includes two silencing structures 232 . The two silencing structures 232 are disposed oppositely on both sides of the first air outlet 22 . The base 231 forms an air inlet area 233 corresponding to each silencing structure 232 . , and each sound-absorbing structure 232 has a plurality of sub-airflow channels 2321. In this way, the airflow on both sides of the first air outlet 22 first flows to the silencing structure 232 through the air inlet area 233 to reduce noise, and then flows to the first air outlet 22 , thereby improving the noise reduction effect of the atomizer 100 .

The atomizer 100 has two air inlets 11, and the base body 231 has an air inlet 2312 respectively connected with the two air inlets 11. The two air inlets 2312 are arranged oppositely, and one air inlet 2312 and an air inlet area 233 connected. In this way, the external airflow can flow from both ends of the atomizer 100 (both ends in the width direction of the atomizer 100) to the two air inlets 11, and from the two air inlets 11 to the two air inlets 2312. , flows from the two air inlets 2312 to the two air inlet areas 233 , and is muffled by the two silencing structures 232 to flow from the first air outlet 22 into the atomization chamber 21 , thereby facilitating the flow of air in the atomizer 100 .

The atomization base 23 also includes a transition piece 234 , which is disposed in the airflow chamber 30 and protrudes from the bottom surface 2311 of the base 231 . The transition piece 234 has a transition channel 2341 that is connected between the branch airflow channels 2321 of the two muffler structures 232 and the first air outlet 22 . Due to the arrangement of the transition piece 234, the airflow flowing out from the divided airflow channels 2321 of the two muffler structures 232 is first guided by the transition channel 2341 and then flows to the first air outlet 22, so as to avoid interference caused by the interference of the airflows on both sides. It is convenient for the airflow on both sides to flow out from the first air outlet 22.

The transition piece 234 includes two transition plates 2342. The two transition plates 2342 are oppositely arranged on both sides of the first air outlet 22 in the first direction, and a transition channel 2341 is formed between the two transition plates 2342. It should be understood that in other embodiments, the transition piece 234 may also include only one transition plate 2342, and the transition channel 2341 is opened on the transition plate 2342, which is not limited here.

In one specific embodiment, the transition plate 2342 is cylindrical and extends in a direction away from the bottom surface 2311. In this way, the outer surfaces of the two transition plates 2342 form the above-mentioned transition channel 2341, and the smooth outer surface facilitates guiding the airflow into the first air outlet 22. . In another specific embodiment, the transition plate 2342 is in the shape of a regular triangular prism extending in a direction away from the bottom surface 2311 , and any vertex of the regular triangular prism is opposite to the first air outlet 22 . In this arrangement, since the vertex of the regular triangular prism is opposite to the first air outlet 22 , the air flows on both sides meet exactly at the vertex of the regular triangular prism and are guided into the first air outlet 22 for discharge.

Referring to Figures 5 and 6, another embodiment of the present application provides an atomizer 100. The difference between this embodiment and the above embodiment is:

Referring to FIGS. 7 and 8 , the sound attenuation structure 232 has a central channel 2323 and expansion chambers respectively distributed on at least one side of the central channel 2323 in the first direction. The central channel 2323 and the expansion chamber are both used to form the partial airflow channel 2321. Through the above arrangement, when the main airflow in the air inlet area 233 flows to the muffler structure 232, it first enters the central channel 2323, and enters the expansion chamber from the central channel 2323 for expansion. The expanded airflow expands from the central channel 2323 as the branch airflow channel 2321 and expands. Chamber decelerates and discharges, thereby achieving the purpose of reducing noise.

Specifically, expansion chambers are formed on both sides of the central channel 2323. The silencing structure 232 includes a number of second silencing blocks 2326 arranged at intervals in the flow direction of the main airflow (the width direction of the atomizer 100). The central channel 2323 runs through all the second silencing blocks 2326 in the flow direction of the main airflow. Each phase A first expansion chamber 2324 and a second expansion chamber 2325 distributed on both sides of the central channel 2323 in the first direction (thickness direction of the atomizer 100) are formed between two adjacent second silencer blocks 2326. In this way, the airflow in the central channel 2323 can flow from both sides to the first expansion chamber 2324 and the second expansion chamber 2325 for expansion, so as to further improve the noise reduction effect.

It should also be noted here that in order to facilitate the flow of air, there is a gap between each second silencer block 2326 and the inner wall of the bottom case 14 .

Further, continuing to refer to Figure 8, each second silencing block 2326 includes a first part 2327 and a second part 2328. A central channel 2323 is formed between the first part 2327 and the second part 2328 of all second silencing blocks 2326. A first expansion chamber 2324 is formed between the first portions 2327 of the second silencing blocks 2326, and a second expansion chamber 2325 is formed between the second portions 2328 of each adjacent two second silencing blocks 2326. The distance between the first part 2327 and the second part 2328 of each first muffler block 2322 gradually increases from the end close to the air inlet area 233 to the end close to the first air outlet 22 . That is, the extension direction of the first part 2327 and the extension direction of the second part 2328 are both inclined with the width direction of the atomizer 100 , that is to say, each second silencer block 2326 is a flare-shaped structure facing the first air outlet 22 .

Through the above arrangement, each second silencing block 2326 has a silencing bowl structure, so the airflow in the central channel 2323 can easily flow to the first expansion chamber 2324 and the second expansion chamber 2325 to expand, so as to achieve the purpose of silencing and reducing noise and improve user experience. .

In the flow direction of the main airflow, part of the second silencing block 2326 located at the next level is located within the second silencing block 2326 at the upper level.

This arrangement is similar to connecting multiple silencing bowls together. The airflow expands each time it passes through a silencing bowl to achieve the purpose of silencing and reducing noise.

Specifically, each silencing structure 232 includes three second silencing blocks 2326 . It should be understood that in other embodiments, the number of second silencing blocks 2326 included in each silencing structure 232 is not limited.
