The geometric flow cross-sectional area of the silencing channel is larger than the geometric flow cross-sectional area of the first air inlet and the geometric flow cross-sectional area of the silencing channel is larger than the geometric flow cross-sectional area of the air outlet.
[0009] The first air inlet, the muffler, and the air outlet are connected to form a first air passage.
[0010] Optionally, the silencing channel includes a first silencing cavity, a first vent hole, and a silencing groove. The first vent hole is opened in the plate and passes through the first plate surface and the second plate surface. The first silencing cavity is formed on the second plate surface. The two ends of the first silencing cavity are respectively connected to the first air inlet hole and the first vent hole. The first silencing cavity is provided with the plurality of grooves and protrusions. The silencing groove is formed on the first plate surface and connects the first vent hole and the air outlet hole.
[0011] Optionally, a sound-absorbing wall is provided on the second plate surface, and the first sound-absorbing cavity is formed by one side wall of the sound-absorbing wall and the second plate surface. At least a portion of the wall surface of the sound-absorbing wall is curved, and the end of the sound-absorbing wall away from the first air inlet surrounds the first air vent.
[0012] Optionally, in the direction perpendicular to the second plate surface, the first vent and the sound-absorbing groove are located on one side of the sound-absorbing wall, the sound-absorbing wall and the sound-absorbing groove are staggered, the sound-absorbing wall, the first vent and the sound-absorbing groove partially overlap, and the opposite portion of the overlapping portion of the sound-absorbing wall and the first vent bends toward the direction away from the first vent.

The silencing channel also includes a second silencing cavity, which is formed on the second plate surface. The second silencing cavity connects the second air inlet and the first silencing cavity. The second silencing cavity is also provided with the plurality of grooves and protrusions.
[0015] Optionally, the silencing channel further includes a second vent hole and a third silencing cavity.

[0020] In the airway structure of this application, the geometric flow cross-sectional area of the silencer channel is larger than that of the first air inlet and the air outlet. The silencer channel is provided with multiple grooves and protrusions. After the high-speed airflow passes through the narrow first air inlet, it enters the wide silencer channel. The high-speed airflow diffuses in the silencer channel and touches multiple grooves and protrusions, changing the propagation direction of the airflow and increasing the propagation path. Some sound waves are weakened by multiple grooves and protrusions through reflection, scattering, and phase interference.

The first airway has a compact structure, low airflow resistance, and excellent broadband silencer effect, which solves the contradiction between insufficient silencer and volume limitation in the prior art and improves the user's suction experience.

[0031] This application proposes an air duct structure, comprising a plate, a first air inlet, an air outlet, and a silencer channel. The plate includes a first plate surface and a second plate surface that are opposite to each other. The first air inlet is formed in the plate and extends through the first and second plate surfaces, directly connecting to the outside atmosphere. The air outlet is formed in the plate and extends through the first and second plate surfaces. The silencer channel is formed on the first and / or second plate surfaces, with its two ends connected to the first air inlet and the air outlet, respectively. The silencer channel has multiple grooves and protrusions. The geometric flow cross-sectional area of the silencer channel is larger than that of the first air inlet, and the geometric flow cross-sectional area of the silencer channel is larger than that of the air outlet. The first air inlet, the silencer channel, and the air outlet are connected to form the first air duct.
[0032] In the airway structure of this application, the geometric flow cross-sectional area of the silencer channel is larger than that of the first air inlet and the air outlet. The silencer channel is provided with multiple grooves and protrusions. After the high-speed airflow passes through the narrow first air inlet, it enters the wide silencer channel. The high-speed airflow diffuses in the silencer channel and touches multiple grooves and protrusions, changing the propagation direction of the airflow and increasing the propagation path. Some sound waves are weakened by multiple grooves and protrusions through reflection, scattering, and phase interference. The sound energy is also absorbed by the silencer channel and multiple grooves and protrusions during propagation. As a result, the noise generated by the gas flow can be effectively reduced in the first airway, significantly improving the user's suction experience.
[0033] The following will mainly describe the specific structure of the airway.
[0034] Please refer to the following: Figure 1 and Figure 2 The airway structure 100 of this application includes a plate 110. The plate 110 is plate-shaped and includes a first plate surface 111 and a second plate surface 112 that are opposite to each other. The second plate surface 112 is uneven. A sound-absorbing wall 113 is provided on the second plate surface 112. At least a portion of the wall surface of the sound-absorbing wall 113 is curved, that is, the wall surface of the sound-absorbing wall 113 has multiple protrusions and grooves. The sound-absorbing wall 113 can be formed by recessing from the second plate surface 112 towards the first plate surface 111; in other words, the sound-absorbing wall 113 and the second plate surface 112 are integrally formed. Therefore, gas leakage from the gap between the sound-absorbing wall 113 and the second plate surface 112 can be prevented.
[0035] Please refer to the following: Figure 1 and Figure 2 The air duct structure 100 of this application includes a first air inlet 121 and a second air inlet 122. Both the first air inlet 121 and the second air inlet 122 are located on the plate 110 and extend through the first plate surface 111 and the second plate surface 112. The first air inlet 121 and the second air inlet 122 are used to directly connect to the outside atmosphere. The shapes of the first air inlet 121 and the second air inlet 122 can be circular, elliptical, racetrack-shaped, polygonal, or irregular, etc. The first air inlet 121 and the second air inlet 122 are located at one end of the plate 110.
[0036] Please refer to the following: Figure 1 and Figure 2 The air duct structure 100 of this application includes an air outlet 160, which is formed in the plate 110 and passes through the first plate surface 111 and the second plate surface 112. The shape of the air outlet 160 can also be circular, elliptical, racetrack-shaped, polygonal, or irregular. The air outlet 160 is formed at the other end of the plate 110.
[0037] The geometric flow cross-sectional area of the air outlet 160 can be greater than, equal to, or less than the geometric flow cross-sectional area of the first air inlet 121 / second air inlet 122. The geometric flow cross-sectional area of the air outlet 160 can be less than the sum of the geometric flow cross-sectional areas of the first air inlet 121 and the second air inlet 122. The geometric flow cross-sectional area of the air outlet 160 can be greater than or equal to 0.8 mm. 2 and less than or equal to 1.5mm 2 Therefore, gas can flow out of the outlet 160 at a relatively low decibel level and a suitable flow rate. Furthermore, the geometric flow cross-sectional area of the outlet 160 can be 0.8 mm². 2 ~1.2mm 2 0.9mm 2 ~1.2mm 2 1mm 2 ~1.5mm 2 0.9mm 2 ~1mm 2 1mm 2 ~1.3mm 2 0.85mm 2 ~1.35mm 2 or 1.3mm 2 ~1.5mm 2 Furthermore, the geometric flow cross-sectional area of the vent 160 can be 0.8 mm². 2 0.85mm 2 0.9mm 2 0.95mm 2 1.0mm 2 1.05mm 2 1.1mm 2 1.15mm 2 1.2mm 2 1.25mm 2 1.3mm 2 1.35mm 2 1.4mm 2 1.45mm 2 Or 1.5mm 2 wait.
[0038] Please refer to the following: Figure 1 and Figure 2The air duct structure 100 of this application includes a silencer channel, which is formed on a first plate surface 111 and / or a second plate surface 112. The two ends of the silencer channel are respectively connected to a first air inlet 121 and an air outlet 160. The silencer channel has multiple grooves and protrusions. The geometric flow cross-sectional area of the silencer channel is larger than the geometric flow cross-sectional areas of the first air inlet 121, the second air inlet 122, and the air outlet 160. After passing through the narrow first air inlet 121 and the second air inlet 122, the high-speed airflow enters the wide silencer channel. The high-speed airflow diffuses within the silencer channel and contacts multiple grooves and protrusions, changing the direction of airflow and increasing the propagation path. Some sound waves are weakened by the multiple grooves and protrusions through reflection, scattering, and phase interference. Sound energy is also absorbed by the silencer channel and the multiple grooves and protrusions during propagation. Therefore, the noise generated by the gas flow can be effectively reduced within the silencer channel.
[0039] The first air inlet 121, the silencer channel, and the air outlet 160 are connected to form a first air passage. The extension length of the first air passage is greater than or equal to 25 mm and less than or equal to 50 mm. Therefore, the length of the first air passage is suitable, the gas flow path is relatively long, and the gas is effectively silenced. Further, the extension length of the first air passage can be 28 mm–50 mm, 29 mm–40 mm, 30 mm–40 mm, 31 mm–35 mm, 32 mm–45 mm, 40 mm–50 mm, or 28 mm–35 mm, etc. Furthermore, the extension length of the first airway can be 28mm, 29mm, 29.5mm, 30mm, 30.5mm, 31mm, 31.5mm, 32mm, 33mm, 34mm, 35mm, 36mm, 37mm, 38mm, 39mm, 40mm, 41mm, 42mm, 43mm, 44mm, 45mm, 46mm, 47mm, 48mm, 49mm, or 50mm.
[0040] Please refer to the following: Figure 1 and Figure 2The silencing channel includes a first silencing cavity 131, a first vent 141, and a silencing groove 150. The first vent 141 is formed in the plate 110 and extends through the first plate surface 111 and the second plate surface 112. The first silencing cavity 131 is formed in the second plate surface 112, and its two ends are respectively connected to the first air inlet 121 and the first vent 141. The first silencing cavity 131 has multiple grooves and protrusions. The geometric flow cross-sectional area of the first silencing cavity 131 is larger than the geometric flow cross-sectional area of the first air inlet 121, the second air inlet 122, and the air outlet 160, thereby enabling the first silencing cavity 131 to silence the gas. The silencing groove 150 is formed in the first plate surface 111 and connects the first vent 141 and the air outlet 160. The first vent 141 is located on one side of the silencing groove 150, and the vent 160 is located at the bottom of the silencing groove 150. The geometric flow cross-sectional area of the silencing groove 150 is larger than the geometric flow cross-sectional area of the first air inlet 121, the second air inlet 122, and the vent 160, so the silencing groove 150 can also achieve the effect of noise reduction.
[0041] Please refer to the following: Figure 1 and Figure 2 The first silencing cavity 131 is formed by one side wall of the silencing wall 113 and the second plate surface 112. At least a portion of the wall surface of the silencing wall 113 is curved, and the end of the silencing wall 113 away from the first air inlet 121 surrounds the first vent 141. In other words, the first silencing cavity 131 is roughly U-shaped, with one end open and communicating with the first air inlet 121, and the other end sealed and surrounding the first vent 141. In the direction perpendicular to the second plate surface 112, the first vent 141 and the silencing groove 150 are located on one side of the wall of the first silencing cavity 131 (i.e., the silencing wall 113), and the first silencing cavity 131 and the silencing groove 150 are staggered, thereby lengthening the gas flow path and improving the silencing effect. The wall (i.e., the sound-absorbing wall 113) of the first silencing cavity 131, the first vent 141, and the sound-absorbing groove 150 partially overlap, thus ensuring a relatively ideal sound-absorbing effect while maintaining a compact structure of the sound-absorbing channel. The relative portions of the overlapping parts of the wall (i.e., the sound-absorbing wall 113) of the first silencing cavity 131 and the first vent 141 are curved away from the first vent 141, resulting in a suitable geometric flow cross-sectional area for the first silencing cavity 131 and thus a better sound-absorbing effect.
[0042] Please refer to the following: Figure 1 and Figure 2The silencing duct also includes a second silencing cavity 132, which is formed on the second plate surface 112. The second silencing cavity 132 connects the second air inlet 122 and the first silencing cavity 131. The second silencing cavity 132 also has multiple grooves and protrusions. The second silencing cavity 132 can also be formed by one side wall of the silencing wall 113 and the second plate surface 112. The geometric flow cross-sectional area of the second silencing cavity 132 is larger than the geometric flow cross-sectional area of the first air inlet 121, the second air inlet 122, and the air outlet 160. The second silencing cavity 132 further reduces noise in the flowing gas. The second silencing cavity 132 can be approximately U-shaped or V-shaped, and its open end connects to the second air inlet 122. The gas flowing into the second air inlet 122 is partially silenced by the second silencer 132 before flowing into the first silencer 131. The gas flowing out of the second silencer 132 and the gas in the first silencer 131 interfere with each other and weaken each other. Thus, the noise reduction effect can be improved while increasing the air intake.
[0043] Please refer to the following: Figure 1 and Figure 2 The silencing channel also includes a second vent 142 and a third silencing cavity 133. The second vent 142 is opened in the plate 110 and passes through the first plate surface 111 and the second plate surface 112. The second vent 142 is connected to the silencing groove 150 and is located on the opposite side of the silencing groove 150 to the first vent 141. The third silencing cavity 133 is formed in the second plate surface 112 and surrounds the second vent 142 (that is, the geometric flow cross-sectional area of the third silencing cavity 133 is larger than the geometric flow cross-sectional area of the second vent 142). The third silencing cavity 133 also has multiple grooves and protrusions. The third silencing cavity 133 can also be formed by the cooperation of the silencing wall 113 and the second plate surface 112. The gas that has been silenced by the first silencing chamber 131 and the second silencing chamber 132 and then flows into the silencing groove 150 can partially flow through the second vent 142 to the third silencing chamber 133, where it is further silenced. Then it flows into the silencing groove 150 through the second vent 142 and finally flows out from the vent 160.
[0044] Please see Figure 1 The third silencing cavity 133 is irregularly annular. Similar to the first silencing cavity 131, in the direction perpendicular to the second plate surface 112, the second vent 142 and the silencing groove 150 are located on one side of the wall of the third silencing cavity 133. The third silencing cavity 133 and the silencing groove 150 are staggered, and the wall of the third silencing cavity 133, the second vent 142 and the silencing groove 150 partially overlap. The opposite part of the wall of the third silencing cavity 133 and the second vent 142 that overlaps bends away from the second vent 142. The third silencing cavity 133 has the aforementioned beneficial effects of the first silencing cavity 131, which will not be described in detail here.
[0045] Please refer to the following: Figure 1 and Figure 2 In the airway structure 100 of this application, through the cooperation of the first air inlet 121, the second air inlet 122, the first silencer 131, the second silencer 132, the third silencer 133, the first vent 141, the second vent 142, the silencer groove 150 and the air outlet 160, it is possible to perform multi-segment, repetitive and cooperative silencer on sounds of different frequency bands. The first airway has a compact structure, low airflow resistance and excellent broadband silencer effect, which solves the contradiction between insufficient silencer and volume limitation in the prior art.
[0046] The ratio of the sum of the volumes of the first silencing chamber 131, the second silencing chamber 132, and the third silencing chamber 133 to the volume of the first airway is greater than or equal to 0.45 and less than or equal to 0.95. Therefore, the silencing effect of the first silencing chamber 131, the second silencing chamber 132, and the third silencing chamber 133 is relatively good. Further, the above ratio can be 0.5–0.6, 0.55–0.65, 0.6–0.8, 0.5–0.7, 0.7–0.95, or 0.75–0.8, etc. Even further, the above ratio can be 0.5, 0.55, 0.6, 0.65, 0.7, 0.75, 0.8, 0.85, 0.9, or 0.95, etc.
[0047] This application also proposes an electronic atomizer, which includes an atomizing device and the aforementioned airway structure 100. The atomizing device has an internal mist-absorbing airway, a second plate 112 is sealed to the atomizing device, and an air outlet 160 communicates with the mist-absorbing airway. The electronic atomizer proposed in this application includes the aforementioned airway structure 100 and possesses all the beneficial effects of the aforementioned airway structure 100, which will not be elaborated further.
