Description

Technical Field

[0001] This utility model relates to the field of atomization equipment technology, and specifically to an atomization device. Background Technology

[0002] Currently, nebulizers are devices that convert liquids into atomized particles, and they are widely used in various fields of the medical industry and other civilian industries. Existing nebulizers are equipped with air guiding channels, which have a significant impact on the nebulization effect and user experience. However, the air guiding channel structure design in existing technologies is poor, resulting in significant airflow noise during use. Utility Model Content

[0003] The purpose of this invention is to provide an atomizing device that reduces the noise during operation.

[0004] To achieve the objectives of this utility model, the following technical solution is provided:

[0005] In a first aspect, this utility model provides an atomizing device, comprising: an atomizing component having an atomizing channel; a battery component connected to the atomizing component, the battery component having an air inlet channel; the battery component includes a bracket, the bracket including a first end face and a second end face opposite to each other in a first direction, the bracket having an air guide channel extending from the first end face to the second end face, the air guide channel communicating with the air inlet channel at one end of the first end face, the air guide channel communicating with the atomizing channel at one end of the second end face, the opening size of the air guide channel at the first end face being larger than the opening size at the second end face, the air guide channel and the atomizing channel being spaced apart in a second direction, the first direction intersecting the second direction.

[0006] It is understandable that, due to the larger opening size of the air guide channel at the first end face and the smaller opening size at the second end face, this tapering design causes the airflow speed to gradually increase as the air guide channel gradually narrows after entering it, while the turbulence level of the airflow decreases. By reducing turbulence, airflow noise can be effectively reduced. Furthermore, the air guide channel and the atomizing channel are spaced apart in the second direction, so that the airflow needs to pass through a buffer space before entering the atomizing channel from the air guide channel, which plays a buffering role. This allows the airflow to be rectified and stabilized to a certain extent before entering the atomizing channel, reducing the impact of airflow and the generation of noise, and reducing the noise of the atomizing device during operation.

[0007] In one embodiment, the air guide channel includes a first section and a second section connected to each other. The first section is opened from the first end face, and the second section is opened from the second end face. The end of the first section away from the second section is connected to the air intake channel, and the end of the second section away from the first section is connected to the atomizing channel. The first section gradually narrows from the first end face to the second end face.

[0008] It is understandable that by designing the first section of the air guide channel as tapering, the impact and vibration during gas flow are reduced, thus reducing airflow noise and improving the user experience.

[0009] In one embodiment, the first segment includes a first transition segment, a main body segment, and a second transition segment. The first transition segment is formed from the first end face. The first transition segment is smoothly connected to one end of the main body segment. The other end of the main body segment is smoothly connected to one end of the second transition segment. The other end of the second transition segment is smoothly connected to the second segment.

[0010] It is understandable that by setting the first section design to include the first transition section, the main section and the second transition section, and with each section smoothly connected, the smooth connection design reduces abrupt changes in gas flow, which can make the airflow in the air guide channel more stable and reduce turbulence and noise for users when drawing.

[0011] In one embodiment, the sidewall of the main body segment and the sidewall of the second segment have a first included angle A, satisfying: 120°≤A≤150°.

[0012] It is understandable that by controlling the first included angle A between the main section and the second section to be between 120° and 150°, the airflow path can be optimized, making the change in flow direction smoother, reducing airflow resistance, improving atomization efficiency, and reducing noise.

[0013] In one embodiment, the second segment tapers from the first end face to the second end face; or, the second segment has the same size in the second direction.

[0014] It is understandable that by designing the second section as either tapered or the same size, the airflow speed and pressure can be adjusted according to specific application requirements, thereby optimizing the atomization effect. The tapered design can be used in situations requiring high airflow speeds, reducing noise, while the same size design is used in situations requiring stable airflow.

[0015] In one embodiment, the first segment is a rotationally symmetric structure; and / or, the second segment is a rotationally symmetric structure.

[0016] It is understandable that by designing the first and / or second sections as rotationally symmetrical structures, the airflow can be evenly distributed within the air guide channel, reducing local turbulence, improving atomization uniformity, and reducing noise.

[0017] In one embodiment, the maximum opening size of the air guide channel at the first end face is D1, and the maximum opening size of the air guide channel at the second end face is D2, satisfying: 1.5≤D1 / D2≤3.0.

[0018] It is understandable that by controlling the ratio of D1 / D2 between 1.5 and 3.0, the flow rate of the air guide channel can be reasonably varied, which can optimize the acceleration effect of the airflow, improve the atomization efficiency, and at the same time avoid the problem of unstable airflow caused by the opening size being too large or too small, and reduce noise.

[0019] In one embodiment, the atomizing component further has a transition channel, one end of which is connected to the air guide channel at the second end face, and the other end is connected to the atomizing channel.

[0020] It is understandable that by setting up a transition channel, the gas can flow more smoothly from the gas guide channel to the atomization channel, which can further optimize the airflow path, reduce airflow resistance, and reduce noise.

[0021] In one embodiment, the bracket has an airflow channel extending from the first end face to the second end face. The airflow channel is spaced apart from the air guide channel and communicates with the transition channel. The battery assembly further includes a starting component. One end of the starting component is connected to the first end face. The starting component is located outside the opening of the airflow channel on the first end face. The starting component and the bracket enclose a drainage channel, which communicates with one end of the airflow channel on the first end face. The starting component is used to control the operation of the atomizer of the atomizing assembly.

[0022] It is understandable that the airflow channel and the air guide channel are spaced apart to ensure smooth airflow and reduce noise caused by turbulence and airflow impact. The spaced airflow channel and the air guide channel can prevent water vapor from interfering with the starting component and extend its service life. The starting component is located outside the opening of the airflow channel and is enclosed with the bracket to form a flow channel, ensuring that the airflow is effectively guided before entering the airflow channel, reducing turbulence and resistance, improving the flow efficiency of the airflow, and improving the efficiency of the airflow control starting component.

[0023] In one embodiment, the battery assembly further includes a housing, which, together with the bracket, encloses a drainage space. One end of the drainage space is connected to the air intake channel, and the other end of the drainage space is connected to an external space. An air intake hole is provided at the end of the housing away from the bracket, with one end of the air intake hole connected to the drainage space and the other end of the air intake hole connected to an external space.

[0024] It is understandable that by setting up a flow space, the gas is buffered before entering the intake channel, reducing the impact and vibration during gas flow. This allows external gas to enter the intake channel more smoothly, reducing airflow resistance and noise. The air intake is connected to the flow space and the external space, which can further optimize the entry path of external gas, reduce airflow resistance, and reduce noise.

[0025] The atomizing device includes an atomizing component and a battery component. The atomizing component has an atomizing channel, and the battery component is connected to the atomizing component. The battery component has an air intake channel and includes a bracket. The bracket includes a first end face and a second end face that are opposite to each other in a first direction. The bracket has an air guide channel extending from the first end face to the second end face. One end of the air guide channel on the first end face is connected to the air intake channel, and one end of the air guide channel on the second end face is connected to the atomizing channel. The opening size of the air guide channel on the first end face is larger than the opening size on the second end face. The air guide channel and the atomizing channel are spaced apart in a second direction, and the first direction intersects the second direction.

[0026] Because the air guide channel has a larger opening size at the first end face and a smaller opening size at the second end face, this tapering design causes the airflow speed to gradually increase as the air guide channel gradually narrows after entering it, while the turbulence level of the airflow decreases. By reducing turbulence, airflow noise can be effectively reduced. Furthermore, the air guide channel and the atomizing channel are spaced apart in the second direction, so that the airflow needs to pass through a buffer space before entering the atomizing channel from the air guide channel. This buffering effect allows the airflow to be rectified and stabilized to a certain extent before entering the atomizing channel, reducing airflow impact and noise generation, and reducing the noise of the atomizing device during operation.

When a component is said to be "connected" to another component, it can be directly connected to the other component or it may be in a middle component.

[0034] Unless otherwise defined, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used in this invention includes any and all combinations of one or more of the associated listed items.

[0035] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0036] This utility model embodiment provides an atomizing device 100, please refer to... Figure 1 It includes an atomizing component 10 and a battery component 11.

[0037] The atomizing assembly 10 has an atomizing channel 101. The inner wall surface of the atomizing channel 101 is chemically polished, resulting in a smooth inner wall surface. This reduces friction between the flowing gas and the inner wall surface of the atomizing channel 101, thereby reducing noise. Optionally, a guide vane is provided within the atomizing channel 101 to guide the airflow along a predetermined path, preventing airflow deviation and eddies, reducing turbulence, and thus reducing noise.

[0038] The battery assembly 11 is connected to the atomizing assembly 10, and the battery assembly 11 has an air intake channel 12. The inner wall surface of the air intake channel 12 is chemically polished, making the inner wall surface of the air intake channel 12 smooth, which can reduce frictional resistance during gas flow and reduce noise.

[0039] Battery assembly 11 includes bracket 13, please refer to Figure 1 and Figure 2 The bracket 13 includes a first end face 131 and a second end face 132 facing away from each other in the first direction X. The bracket 13 has an air guide channel 14 extending from the first end face 131 to the second end face 132. One end of the air guide channel 14 is connected to the air inlet channel 12 in the first end face 131, and one end of the air guide channel 14 is connected to the atomizing channel 101 in the second end face 132. The opening size of the air guide channel 14 at the first end face 131 is larger than the opening size at the second end face 132. The air guide channel 14 and the atomizing channel 101 are spaced apart in the second direction Y, and the first direction X and the second direction Y intersect.

[0040] Because the opening size of the air guide channel 14 is larger at the first end face 131 and smaller at the second end face 132, this tapering design causes the airflow speed to gradually increase as the air guide channel 14 gradually narrows after entering it, while the turbulence of the airflow decreases. By reducing turbulence, airflow noise can be effectively reduced. Furthermore, the air guide channel 14 and the atomizing channel 101 are spaced apart in the second direction Y, so that the airflow needs to pass through a buffer space before entering the atomizing channel 101 from the air guide channel 14, which plays a buffering role. This allows the airflow to be rectified and stabilized to a certain extent before entering the atomizing channel 101, reducing the impact of the airflow and the generation of noise, and reducing the noise of the atomizing device 100 during operation.

[0041] Specifically, the air guide channel 14 is used to guide gas from the air inlet channel 12 to the atomizing channel 101. Optionally, the air guide channel 14 is tapered from the first end face 131 to the second end face 132. This tapering design allows the airflow to gradually accelerate, avoiding noise caused by abrupt changes in airflow velocity. Optionally, the air guide channel 14 adopts a parabolic tapering design to further reduce the impact of gas flow, thereby reducing noise. Optionally, an airflow guide vane is provided within the air guide channel 14 to guide the airflow along a predetermined path, avoiding airflow deviation and eddies, reducing turbulence, and thus reducing noise.

[0042] Optionally, the opening of the air guide channel 14 at the first end face 131 is circular, and the inner wall of the air guide channel 14 is provided with a smooth chamfer at the opening. The circular opening and the smooth chamfer can make the airflow enter the air guide channel 14 evenly and avoid the airflow from generating impact and noise at the inlet.

[0043] In one embodiment, please refer to Figure 1 and Figure 2 The air guide channel 14 includes a first section 141 and a second section 142 that are connected. The first section 141 is opened from the first end face 131, and the second section 142 is opened from the second end face 132. The end of the first section 141 away from the second section 142 is connected to the air intake channel 12, and the end of the second section 142 away from the first section 141 is connected to the atomizing channel 101. The first section 141 gradually narrows from the first end face 131 to the second end face 132.

[0046] Optionally, a first guide channel is formed on the inner wall surface of the first section 141. The first guide channel further guides the gas flow direction, causing the airflow to flow stably along the first guide channel, reducing turbulence, and thus reducing noise. Optionally, a second guide channel is formed on the inner wall surface of the second section 142. The second guide channel further guides the gas flow direction, causing the airflow to flow stably along the second guide channel, reducing turbulence, and thus reducing noise.

[0047] Optionally, the first segment 141 and the second segment 142 are designed with reinforcing ribs to ensure structural stability and prevent vibration from generating noise.

[0048] Optionally, the first segment 141 has a tapering angle of 10° to 15° from the first end face 131 to the second end face 132, to ensure that the gas flow gradually accelerates, reducing impact and thus reducing noise.

[0049] Optionally, the ratio of the length of the first segment 141 to the length of the second segment 142 can be between 2:1 and 4:1 to optimize the noise reduction effect under different flow rates. By adopting an appropriate length ratio, noise can be avoided from being generated by drastic changes in airflow speed.

[0050] Optionally, the first segment 141 and the second segment 142 are integrally molded, with no gaps at the connection between the first segment 141 and the second segment 142, to avoid gas leakage and to avoid generating additional noise.

[0051] Optionally, the second segment 142 is connected to the first segment 141 by an arc transition to ensure smooth gas flow and thus reduce noise.

[0052] Optionally, the first segment 141 and the second segment 142 are made of a high-gloss material to reduce frictional resistance during gas flow, thereby reducing noise. Optionally, the first segment 141 and the second segment 142 are made of high-density sound-insulating material to further reduce noise transmission.

[0053] Specifically, by designing the first section 141 of the air guide channel 14 as a tapered shape, the tapered design reduces the impact and vibration during gas flow, thereby reducing airflow noise and improving the user experience. In addition, the tapered design of the first section 141 allows the gas to gradually accelerate within the first section 141 before entering the atomization channel 101, thus improving atomization efficiency.

[0054] In one embodiment, please refer to Figure 2 The first segment 141 includes a first transition segment 1411, a main segment 1412, and a second transition segment 1413. The first transition segment 1411 is opened from the first end face 131. The first transition segment 1411 is smoothly connected to one end of the main segment 1412. The other end of the main segment 1412 is smoothly connected to one end of the second transition segment 1413. The other end of the second transition segment 1413 is smoothly connected to the second segment 142.

[0055] Optionally, the first transition section 1411, the main body section 1412, the second transition section 1413, and the second section 142 are all connected by a smooth connection. The smooth connection avoids the airflow from generating violent impacts and eddies at the connection point, thus reducing noise.

[0056] Optionally, the transition angle of the first transition section 1411 is 30° to 45° to ensure smooth gas flow. Optionally, the transition angle of the second transition section 1413 is 30° to 45° to ensure smooth gas flow.

[0057] Optionally, the first transition section 1411, the main body section 1412, and the second transition section 1413 are all integrally molded. There is no gap at the connection between the first transition section 1411 and the main body section 1412, and there is no gap at the connection between the main body section 1412 and the second transition section 1413, so as to avoid gas leakage and avoid generating additional noise.

[0058] Optionally, the main body section 1412 adopts a streamlined design to reduce turbulence noise during gas flow.

[0059] Optionally, the first transition section 1411, the main body section 1412, and the second transition section 1413 are all made of high-gloss materials to reduce frictional resistance during gas flow and reduce noise.

[0060] Optionally, spiral guide grooves are provided on the inner wall surface of the first transition section 1411, the inner wall surface of the main body section 1412, and the inner wall surface of the second transition section 1413 to further guide the gas flow direction, so that the airflow flows stably along the spiral guide grooves, reducing turbulence and noise.

[0061] Specifically, the design of the first section 141 includes a first transition section 1411, a main section 1412, and a second transition section 1413, with each section smoothly connected. This smooth connection design reduces abrupt changes in gas flow, allowing the airflow to flow more smoothly within the air guide channel 14, thus reducing turbulence and noise for the user during suction.

[0062] In one embodiment, please refer to Figure 2 The side wall of the main segment 1412 and the side wall of the second segment 142 have a first included angle A, which satisfies: 120°≤A≤150°.

[0063] Optionally, the sidewalls of the main section 1412 and the second section 142 are both designed with smooth curved surfaces to reduce frictional resistance during gas flow and reduce noise.

[0064] Optionally, both the main body section 1412 and the second section 142 are made of high-gloss materials to reduce frictional resistance during gas flow and reduce noise.

[0065] Optionally, the sidewalls of the main body section 1412 and the sidewalls of the second section 142 are chemically polished to make them smooth, which can reduce the friction between the flowing gas and the sidewalls of the main body section 1412 and the sidewalls of the second section 142, thereby reducing noise.

[0066] Specifically, by controlling the first included angle A between the main body segment 1412 and the second segment 142 to between 120° and 150°, the airflow path can be optimized, making the change in flow direction smoother, reducing airflow resistance, improving atomization efficiency, and reducing noise.

[0067] In one embodiment, please refer to Figure 2 The second segment 142 is tapered from the first end face 131 to the second end face 132; or, the second segment 142 has the same size in the second direction Y.

[0068] Optionally, the second segment 142 adopts a multi-stage stepped tapering, with each stage tapering at a 2° angle, to gradually reduce airflow impact noise.

[0069] Optionally, the second segment 142 has a taper angle of 5° to 10° from the first end face 131 to the second end face 132 to ensure that the gas flow gradually accelerates, reducing impact and thus reducing noise.

[0070] Specifically, by designing the second segment 142 as either tapered or the same size, the airflow speed and pressure can be adjusted according to specific application requirements, thereby optimizing the atomization effect. The tapered design can be used in situations requiring high airflow speeds, reducing noise, while the same size design is used in situations requiring stable airflow.

[0071] In one embodiment, please refer to Figure 2 The first segment 141 is a rotationally symmetric structure; and / or the second segment 142 is a rotationally symmetric structure.

[0072] Optionally, the inner wall surface of the first section 141 adopts a hyperbolic tapering surface, and the inner wall surface of the second section 142 adopts a hyperbolic tapering surface to reduce airflow separation noise.

[0073] Optionally, the first segment 141 has a circular cross-section with a uniform inner diameter to ensure uniform gas flow and reduce noise. Optionally, the second segment 142 has a circular cross-section with a uniform inner diameter to ensure uniform gas flow and reduce noise.

[0074] Optionally, a porous sound-absorbing material layer is symmetrically embedded in the inner wall surface of the first section 141 and in the inner wall surface of the second section 142 to absorb high-frequency airflow noise.

[0075] Optionally, the atomizing channel 101 has a rotationally symmetric structure, and there is a first distance M between the axis of the first segment 141 and the axis of the atomizing channel 101.

[0076] Specifically, by designing the first section 141 and / or the second section 142 as rotationally symmetric structures, the airflow can be evenly distributed within the air guide channel 14, reducing local turbulence, improving atomization uniformity, and reducing noise.

[0077] In one embodiment, please refer to Figure 2The maximum opening size of the air guide channel 14 at the first end face 131 is D1, and the maximum opening size of the air guide channel 14 at the second end face 132 is D2, satisfying: 1.5≤D1 / D2≤3.0.

[0078] Optionally, D1 / D2 can be controlled within an appropriate range to ensure reasonable flow rate changes during gas flow, reduce impact, and thus reduce noise.

[0079] Optionally, when the air guide channel 14 is a circular channel, the maximum opening size of the air guide channel 14 at the first end face 131 is the first diameter, and the maximum opening size of the air guide channel 14 at the second end face 132 is the second diameter.

[0080] Specifically, by controlling the ratio of D1 / D2 between 1.5 and 3.0, the flow rate of the air guide channel 14 changes reasonably, which can optimize the acceleration effect of the airflow, improve the atomization efficiency, and at the same time avoid the problem of unstable airflow caused by the opening size being too large or too small, and reduce noise.

[0081] In one embodiment, please refer to Figure 1 and Figure 2 The atomizing component 10 also has a transition channel 15, one end of which is connected to the air guide channel 14 at the second end face 132, and the other end is connected to the atomizing channel 101.

[0082] Optionally, the inner wall of the transition channel 15 is coated with a first sound-absorbing material layer, which can absorb the sound wave energy during the airflow transmission process and reduce noise.

[0083] Optionally, a first rectifier is provided at the connection between the transition channel 15 and the air guide channel 14, and a second rectifier is provided at the connection between the transition channel 15 and the atomizing channel 101. The first and second rectifiers can streamline the airflow, making it flow more evenly and stably, and reducing noise.

[0084] Optionally, the transition channel 15 is provided with multiple second noise-absorbing filters, which can filter impurities and eddies in the airflow, reduce airflow impact, and thus reduce noise.

[0085] Optionally, the connection between the transition channel 15 and the air guide channel 14 adopts a rounded transition design, and the connection between the transition channel 15 and the atomizing channel 101 adopts a rounded transition design to ensure that the gas flow is not abrupt and reduce noise.

[0086] Optionally, a transition guide groove is provided on the inner wall of the transition channel 15 to guide the gas flow direction and reduce turbulence noise.

[0087] Optionally, the support 13 has a non-through first buffer cavity opened from the second end face 132. The first buffer cavity is connected to the transition channel 15 to reduce the impact noise during gas flow and facilitate the formation of local low air pressure during suction, thereby reducing suction resistance.

[0088] Optionally, a transition guide plate can be installed in the transition channel 15 to guide the airflow along a predetermined path, avoid airflow deviation and eddies, reduce turbulence, and thus reduce noise.

[0089] Specifically, by setting the transition channel 15, the gas flows more smoothly from the gas guide channel 14 to the atomization channel 101, which can further optimize the airflow path, reduce airflow resistance, and reduce noise.

[0090] In one embodiment, please refer to Figure 1 and Figure 2 The bracket 13 has an airflow channel 16 extending from the first end face 131 to the second end face 132. The airflow channel 16 is spaced apart from the air guide channel 14 and is connected to the transition channel 15. The battery assembly 11 also includes a starting assembly 17. One end of the starting assembly 17 is connected to the first end face 131. The starting assembly 17 is located outside the opening of the airflow channel 16 on the first end face 131. The starting assembly 17 and the bracket 13 enclose a drainage channel 18. The drainage channel 18 is connected to one end of the airflow channel 16 on the first end face 131. The starting assembly 17 is used to control the operation of the atomizer of the atomizing assembly 10.

[0091] Optionally, the inner wall of the airflow channel 16 is provided with sound-absorbing material, which can absorb noise in the airflow and reduce noise transmission. Optionally, the inner wall of the airflow channel 16 is provided with multiple sound-absorbing sponges, which are made of open-pore sponge material and can absorb noise in the airflow and reduce noise transmission.

[0092] Optionally, the inner wall of the airflow channel 16 is provided with multiple guide vanes. The guide vanes are streamlined and can guide the airflow to flow smoothly, reducing airflow turbulence and noise generation.

[0093] Optionally, the inner wall of the airflow channel 16 is provided with multiple sound-absorbing grooves, all of which extend along the first direction X. As the airflow flows along the multiple sound-absorbing grooves, it can effectively absorb noise in the airflow.

[0094] Optionally, the independently configured airflow channel 16 is connected to the microphone 21 of the activation component 17 to form a dedicated sensing airflow path. Based on the pressure difference of the airflow on both sides of the microphone 21, the microphone 21 selects its working state. This design allows the microphone 21 to detect only the flow of pure air, reducing interference from the atomizing medium, avoiding signal distortion caused by atomized particles adhering to the sensor, and improving the accuracy of suction action recognition.

[0095] It is understandable that the airflow channel 16 and the air guide channel 14 are spaced apart to allow the airflow to flow smoothly and reduce the noise generated by turbulence and airflow impact.

[0096] Optionally, the inner wall of the drainage channel 18 is provided with a sound-absorbing material layer. The sound-absorbing material layer is made of porous material and can absorb the noise generated by the airflow and reduce the transmission of noise.

[0098] Optionally, the airflow channel 16 adopts a constant diameter structure, and the guide channel 18 also adopts a constant diameter structure, which contrasts with the tapered structure of the guide channel 14 to ensure that the airflow resistance is minimized and the suction resistance is reduced.

[0099] Optionally, the inner wall of the flow channel 18 is provided with multiple guide plates. The guide plates are streamlined and can guide the airflow smoothly into the airflow channel 16, reducing airflow turbulence and noise.

[0100] Optionally, the starting component 17 is independently located outside the opening of the airflow channel 16 and indirectly connected to the airflow channel 16 through the drainage channel 18, thus physically isolating it from the atomizing airflow.

[0101] It is understood that the airflow channel 16 and the air guide channel 14 are spaced apart to prevent water vapor from interfering with the starting component 17 and extend its service life. The starting component 17 is located outside the opening of the airflow channel 16 and forms a flow guide channel 18 with the bracket 13, ensuring that the airflow is effectively guided before entering the airflow channel 16, reducing turbulence and resistance, improving the flow efficiency of the airflow, and improving the efficiency of the airflow control starting component 17.

[0102] In one embodiment, please refer to Figure 1 and Figure 2 The battery assembly 11 also includes a housing 19, which, together with the bracket 13, encloses a drainage space 20. One end of the drainage space 20 is connected to the air intake channel 12, and the other end of the drainage space 20 is used to connect with the external space. An air intake hole 191 is provided at the end of the housing 19 away from the bracket 13.

[0104] Optionally, the housing 19 is made of sound-insulating material to further reduce noise.

[0105] Specifically, by setting up the flow space 20, the gas is buffered before entering the intake channel 12, reducing the impact and vibration during gas flow, allowing external gas to enter the intake channel 12 more smoothly, reducing airflow resistance and noise.

[0106] Optionally, the inner wall of the air inlet 191 is coated with a second sound-absorbing material layer, which can absorb the sound wave energy during the airflow transmission process and reduce noise.

[0107] Optionally, the air intake 191 tapers from the external space towards the flow space 20. This taper design allows the airflow to gradually accelerate, avoiding noise caused by abrupt changes in airflow speed. Optionally, the air intake 191 employs a parabolic taper design to further reduce the impact of airflow, thereby reducing noise. Optionally, the air intake 191 uses a multi-stage stepped taper, with each stage having a taper angle of 2°, progressively reducing airflow impact noise.

[0108] Optionally, an air intake guide vane can be provided inside the air intake 191 to guide the airflow along a predetermined path, avoid airflow deviation and eddies, reduce turbulence, and thus reduce noise.

[0109] Optionally, the end of the housing 19 away from the bracket 13 has multiple air inlets 191, which are spaced apart. Alternatively, the multiple air inlets 191 are spaced at equal intervals.

[0110] Optionally, the connection between the air intake 191 and the external space is made by a rounded transition, and the connection between the air intake 191 and the drainage space 20 is made by a rounded transition, to ensure smooth gas flow and thus reduce noise.

[0111] Optionally, a noise-absorbing protrusion is provided at the connection between the air intake 191 and the external space. The noise-absorbing protrusion can interfere with the formation of airflow vortices and reduce vortex noise at the connection between the air intake 191 and the external space. Optionally, multiple spaced second noise-absorbing filters are provided at the connection between the air intake 191 and the external space. The second noise-absorbing filters can filter vortices in the airflow and reduce airflow impact and noise.

[0112] Optionally, the air intake 191 can be a circular hole, an elliptical hole, or a polygonal hole, and no limitation is made here.

[0113] Optionally, an air intake guide groove can be formed on the inner wall of the air intake 191. The air intake guide groove further guides the direction of gas flow, which can make the airflow flow stably along the air intake guide groove, reduce turbulence, and thus reduce noise.

[0114] Optionally, a filter screen is provided at the air inlet 191 to prevent impurities from entering. Optionally, the inner wall surface of the air inlet 191 is chemically polished, and the smooth inner wall surface of the air inlet 191 can reduce frictional resistance during gas flow and reduce noise.

[0115] Optionally, a honeycomb-shaped buffer mesh can be provided at the air intake 191 to disperse the airflow impact and thus reduce noise.

[0116] Specifically, by setting the air intake 191, the entry path of external gas can be further optimized, airflow resistance can be reduced, and noise can be lowered.
