Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a turbine box device and a ventilator. Background Technology

[0002] Home-use ventilators are commonly used for the daily respiratory care of patients with respiratory conditions, primarily during nighttime sleep. Therefore, the noise level of the ventilator during operation is critical, generally not exceeding 35 decibels. As a vital component of the ventilator, low noise performance is an essential requirement for the turbine housing.

[0003] Currently, common methods for reducing the noise of the turbine housing in home ventilators on the market mainly involve selecting a low-noise, high-speed turbine fan or filling the airway walls of the turbine housing with sound-absorbing cotton. However, using a low-noise, high-speed turbine fan significantly increases costs; using sound-absorbing cotton is less effective, and due to its material properties, it gradually turns into dust over time. Furthermore, the turbine housing is inconvenient to disassemble and reassemble, making it impossible for users to regularly replace the internal sound-absorbing cotton. This can lead to the inhalation of this dusty cotton by the patient, posing a significant safety hazard.

[0004] Therefore, the existing technology still needs to be improved and enhanced. Summary of the Invention

[0005] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a turbine box device and a ventilator to effectively reduce the noise generated during the operation of the turbine box device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A turbine box device, comprising:

[0008] The housing, a partition disposed within the housing, and a turbine fan disposed on the partition, the partition dividing the housing into a communicating upper receiving cavity and a lower receiving cavity;

[0009] The lower receiving cavity is provided with a guide structure, which divides the lower receiving cavity into a first channel and a second channel. The upper receiving cavity connects the first channel and the second channel. The first channel is located on one side of the second channel, and the second channel surrounds the axis of the air inlet of the turbine fan.

[0010] The housing has a first opening end that communicates with the first channel and a second opening end that communicates with the air outlet of the turbine fan. The air inlet of the turbine fan is connected to the second channel to drive the gas flow between the first opening end and the second opening end.

[0011] The guiding structure includes a first guide piece, one end of which is fixedly connected to the inner wall of the housing, and the other end of which is connected to the side wall of the second channel. The first guide piece and the peripheral wall of the second channel form a first guiding side wall, and the first guiding side wall and the peripheral wall of the housing are spaced apart to form the first channel.

[0012] The guiding structure further includes a second guide plate and a third guide plate. The two ends of the second guide plate are connected to the peripheral wall of the housing to form a second guide sidewall. One end of the third guide plate is connected to the second guide sidewall. One end of the third guide plate is bent inward around the axis of the air inlet of the turbine fan to form a third guide sidewall. The second guide sidewall and the third guide sidewall are spaced apart to form the second channel.

[0013] The separator is recessed into the third guide sidewall near the second channel to form a receiving collar. The turbine fan is mounted on the receiving collar, and the air inlet of the turbine fan faces downward. There is a gap between the lower end face of the receiving collar and the bottom surface of the housing for gas flow.

[0014] The third guide sidewall extends upward with a mounting boss, and the separator is provided with mounting holes that are adapted to the mounting boss.

[0015] The upper end of the turbine fan is provided with a buffer, and the inner wall of the housing is provided with a joint that is adapted to the buffer.

[0016] The turbine box assembly also includes an outlet adapter for connecting the outlet of the turbine fan to the second open end. The outlet adapter is installed inside the second open end, and one end of the outlet adapter bends outward to cover the end of the second open end. The other end of the outlet adapter is sleeved on the outlet of the turbine fan.

[0017] The air outlet adapter is provided with an annular protrusion adapted to the air outlet of the turbine fan and a ring for contacting the inner wall of the housing, with a buffer gap between the ring and the annular protrusion.

[0018] The turbine box assembly also includes a housing for mounting the housing, the housing having an air supply port adapted to the first opening end, the separator having an air intake adapter fitting into the first opening end to connect the air supply port to the first channel, and the air supply port having sound-absorbing cotton.

[0019] A ventilator comprising the turbine box assembly described above.

[0020] Compared to existing technologies, this invention provides a turbine housing device and a ventilator. The turbine housing device includes: a housing, a partition disposed within the housing, and a turbine fan disposed on the partition. The partition divides the housing into a communicating upper cavity and a lower cavity. A guide structure is provided within the lower cavity, dividing the lower cavity into a first channel and a second channel. The upper cavity connects the first channel and the second channel. The first channel is located on one side of the second channel, and the second channel surrounds the axis of the turbine fan's air inlet. The housing has a first opening end communicating with the first channel and a second opening end communicating with the turbine fan's air outlet. The turbine fan's air inlet communicates with the second channel to drive gas flow between the first opening end and the second opening end. This application uses a combination of upper and lower cavities to achieve a miniaturized design of the turbine housing device. By placing the first and second channels in the lower cavity and connecting them through the upper cavity, a longer gas passage is achieved within a smaller volume, significantly reducing the wind noise generated by the turbine fan during operation.

Detailed Implementation

[0036] To make the objectives, technical solutions, and effects of this invention clearer and more explicit, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0037] It should be noted that when a component is referred to as being "mounted on," "fixed to," or "set on" another component, it can be directly on the other component or may have an intervening component present. When a component is referred to as being "connected to" another component, it can be directly connected to the other component or may have an intervening component present.

[0038] It should also be noted that the directional terms such as left, right, up, and down in the embodiments of the present invention are only relative concepts or are based on the normal use state of the product, and should not be considered as restrictive.

[0039] Home-use ventilators are commonly used for the daily respiratory care of patients with respiratory conditions, mostly during nighttime sleep. Therefore, the noise level of the ventilator during operation is critical, generally not exceeding 35 decibels. The turbine housing, as a crucial component of the ventilator, plays multiple roles, including gas mixing, stabilizing airflow, isolating vibrations, and conducting heat for cooling. It generates noise during operation, which can affect the user; therefore, low noise is an essential requirement for the turbine housing.

[0040] Currently, the common methods for reducing the noise of the turbine box device in home ventilators on the market are mainly by selecting a low-noise, high-speed turbine fan or filling the airway of the turbine device with sound-absorbing cotton. The microporous structure of the sound-absorbing cotton absorbs noise to achieve the purpose of noise reduction. However, the sound-absorbing cotton is limited by its material defects and may have an impact on the human body after long-term use. In addition, the existing turbine box device has a relatively complex structure, and it is inconvenient to replace the sound-absorbing cotton filled in the airway of the turbine device.

[0041] This application aims to provide a turbine box device and a ventilator to effectively reduce the noise generated during the operation of the turbine box device.

[0042] A turbine box device, see below Figures 1-6 The device includes: a housing 1, a partition 2 disposed within the housing 1, and a turbine fan 3 disposed on the partition 2. The partition 2 divides the housing 1 into an upper receiving cavity 4 and a lower receiving cavity 5 that are connected. A guide structure 6 is disposed in the lower receiving cavity 5, which divides the lower receiving cavity 5 into a first channel 51 and a second channel 52. The upper receiving cavity 4 connects the first channel 51 and the second channel 52. The first channel 51 is located on one side of the second channel 52, and the second channel 52 surrounds the axis of the air inlet 30 of the turbine fan 3. The housing 1 has a first opening end 11 that communicates with the first channel 51 and a second opening end 12 that communicates with the air outlet 31 of the turbine fan 3. The air inlet 30 of the turbine fan 3 communicates with the second channel 52 to drive the gas flow between the first opening end 11 and the second opening end 12. In this application, the turbine box device is miniaturized by combining the upper cavity 4 and the lower cavity 5. The first channel 51 and the second channel 52 are set in the lower cavity 5 and connected to the first channel 51 and the second channel 52 through the upper cavity 4, so that a longer gas channel is achieved in a smaller volume, which greatly reduces the wind noise generated when the turbine fan 3 is working.

[0043] In this application, the housing 1 includes a turbine cover 13 and a turbine base 14. The partition 2 is located between the turbine cover 13 and the turbine base 14 and is fixed by screwing. The partition 2 can be made of silicone. The partition 2 can divide the internal space of the housing 1 into an upper receiving cavity 4 and a lower receiving cavity 5, which is beneficial to extend the gas passage. On the other hand, when the partition 2, the turbine cover 13 and the turbine base 14 are screwed together, the partition 2 can seal the connection between the turbine cover 13 and the turbine base 14 to prevent gas leakage and affect the working efficiency of the turbine box device.

[0044] For further details, please refer to the following: Figures 1-6 The guide structure 6 includes a first guide piece 61. One end of the first guide piece 61 is fixedly connected to the inner wall of the housing 1, and the other end of the first guide piece 61 is connected to the side wall of the second channel 52. The first guide piece 61 and the peripheral wall of the second channel 52 form a first guide side wall. The first guide side wall and the peripheral wall of the housing 1 are spaced apart to form the first channel 51.

[0045] In this application, the first guide plate 61 extends from the side wall of the housing 1 opposite to the first opening end 11 toward the side of the first opening end 11 and connects with the outer side wall of the second channel 52 to form a first guide side wall. The first guide side wall is approximately parallel to the peripheral wall of the housing 1 that it cooperates to form the first channel 51, which is beneficial to improve the guiding efficiency of the first channel 51 and ensure that the gas can quickly and smoothly enter the upper receiving cavity 4 after passing through the first channel 51.

[0046] A differential pressure flow sensor 511 is installed in the first channel 51. A first differential pressure sampling interface 15 and a second differential pressure sampling interface 16 are installed on the housing 1. The first differential pressure sampling interface 15 and the second differential pressure sampling interface 16 are located on both sides of the differential pressure flow sensor 511, and the first differential pressure sampling interface 15 is located on the side closer to the first opening end 11. A first connecting opening 21 and a second connecting opening 22 are provided on the separator 2. The first connecting opening 21 allows the first differential pressure sampling interface 15 to connect with the first channel 51, and the second connecting opening 22 allows the second differential pressure sampling interface 16 to connect with the first channel 51. The second connecting opening 22 also connects the first channel 51 and the upper receiving cavity 4. Gas enters the first channel 51 from the first opening end 11, passes through the differential pressure flow sensor 511, and the differential pressure is collected by the differential pressure sampling interfaces on both sides of the differential pressure flow sensor 511, thereby calculating the real-time flow rate at the patient's inhalation port. It should be noted that the methods for collecting, calculating, and analyzing differential pressure and flow are existing technologies and are not within the scope of protection of this application.

[0047] For further details, please refer to Figures 1-8The guide structure 6 also includes a second guide plate 62 and a third guide plate 63. The two ends of the second guide plate 62 are connected to the peripheral wall of the housing 1 to form a second guide sidewall. One end of the third guide plate 63 is connected to the second guide sidewall. One end of the third guide plate 63 is bent inward around the axis of the air inlet 30 of the turbine fan 3 to form a third guide sidewall 66. The second guide sidewall and the third guide sidewall 66 are spaced apart to form a second channel 52.

[0048] In this application, the partition 2 is also provided with several connecting holes 23, and each connecting hole 23 is provided with a corresponding flow channel pipe 231 for guiding gas flow, so that the gas enters the upper receiving cavity 4 through the first channel 51 and then enters the second channel 52 from the upper receiving cavity 4; the multiple flow channel pipes 231 are connected by a connecting plate 2311, and the partition 2 is provided with a locking position adapted to the connecting plate 2311 to limit the middle and upper part of the flow channel pipe 231. The locking position is a through groove between two adjacent connecting holes 23. In order to ensure that the gas can smoothly enter the second channel 52 after passing through the flow channel pipe 231, there is a height difference between the lower end of the flow channel pipe 231 and the bottom surface of the shell 1. Furthermore, in order to ensure the stability of the overall flow channel pipe 231, the flow channel pipes at both ends are... The length of 231 is greater than that of the middle flow channel pipe 231, so that the flow channel pipes 231 at both ends can cooperate with the bosses 232 on the shell 1 (specifically, the flow channel pipe 231 is a hollow columnar structure, and the bosses 232 are also hollow columnar, with the flow channel pipe 231 sleeved on the outside of the bosses 232 so that the bosses 232 limit the lower end of the flow channel pipe 231). Furthermore, in order to prevent the bosses 232 from affecting the flow of gas in the flow channel pipes 231 at both ends, guide ports 233 for gas flow are provided on the flow channel pipes 231 at both ends; through the cooperation of the connecting plate 2311 with the locking position and the cooperation of the flow channel pipes 231 at both ends with the bosses 232, the flow channel pipe 231 is limited as a whole, preventing the flow channel pipe 231 from shaking and affecting the normal flow of gas. In this application, there are 5 connecting holes 23, and the connecting holes 23 are arranged in an arc shape to accommodate the second channel 52. Each connecting hole 23 is provided with a flow channel pipe 231. Among them, the three middle flow channel pipes 231 are short flow channel pipes 231, and the two flow channel pipes 231 at both ends are long flow channel pipes 231. The long flow channel pipes 231 cooperate with the boss 232 to limit the five flow channel pipes 231, so that the five flow channel pipes 231 are in a vertical state, ensuring that the gas in the upper receiving cavity 4 flows into the second channel 52.

[0049] The third guide plate 63 in this application serves two purposes: firstly, it connects the second guide sidewall and the third guide sidewall 66, strengthening their structural strength; secondly, it guides the gas, allowing it to flow along the second channel 52 formed between the second and third guide sidewalls 66. The third guide sidewall 66 is arc-shaped, with its starting and ending ends not connected, forming a notch (not shown in the figure) for gas to enter the interior of the third guide sidewall 66 from the second channel 52. The air inlet 30 of the turbine fan 3 faces the interior of the third guide sidewall 66 and is connected to the second channel 52 through the notch. In this application, the first channel 51 is approximately linear, and the second channel 52 is annular. This arrangement allows the two channels to be combined in the lower receiving cavity 5, and then connected to the first channel 51 and the second channel 52 through the upper receiving cavity 4, increasing the path length of the gas flow and helping to reduce the noise generated by the turbine fan 3.

[0050] For further details, please refer to Figures 1-13 The separator 2 is recessed into the third guide sidewall 66 near the second channel 52 to form a receiving collar 24. The turbine fan 3 is installed on the receiving collar 24, and the air inlet 30 of the turbine fan 3 faces downward. There is a gap between the lower end face of the receiving collar 24 and the bottom surface of the housing 1 for gas flow.

[0051] In this application, the air inlet 30 of the turbine fan 3 is located at the lower end of the turbine fan 3 and faces the interior of the third guide sidewall 66. The third guide sidewall 66 supports the separator 2, so that the receiving collar 24 is suspended and located inside the third guide sidewall 66. The setting of the receiving collar 24 allows the turbine fan 3 to be placed, and the turbine fan 3 can be quickly assembled without additional positioning. At the same time, the above assembly method makes the overall structure more compact, which helps to reduce the volume of the turbine box device. The receiving collar 24 is suspended, which plays a role in buffering and vibration reduction. In addition, the third guide sidewall 66 can also limit the receiving collar 24 to prevent the turbine fan 3 and the receiving collar 24 from shaking due to the vibration generated when the turbine fan 3 is working, and ensure that the turbine fan 3 on the receiving collar 24 is as stable as possible during operation.

[0052] For further details, please refer to Figures 1-5The third guide sidewall 66 extends upward with a mounting boss 661, and the partition 2 is provided with mounting holes 25 that are adapted to the mounting boss 661. In this application, there are three mounting bosses 661, and the number of mounting holes 25 corresponds to the number of mounting bosses 661. The mounting holes 25 are arranged around the receiving collar 24. The mounting bosses 661 are inserted into the mounting holes 25, which plays a positioning role for the partition 2 and facilitates the installation of the partition 2. Compared with the partition 2 being supported only by the third guide sidewall 66 without the mounting bosses 661, the combination of the mounting bosses 661 and the mounting holes 25 changes the stress state of the partition 2, and avoids the receiving collar 24 from falling off the partition 2 due to material fatigue caused by the long-term bearing of the weight of the turbine fan 3, which would affect the normal use of the turbine box device.

[0053] For further details, please refer to Figures 1-8 The upper end of the turbine fan 3 is provided with a buffer 32, and the inner wall of the housing 1 is provided with a joint 17 adapted to the buffer 32. The buffer 32 and the joint 17 cooperate to form a buffer area, so as to play a buffering and vibration reduction role when the turbine fan 3 is working.

[0054] In one embodiment of this application, the buffer 32 includes a main body 321 and a wrapping portion 322 located outside the main body 321. The main body 321 is hollow cylindrical (e.g., Figure 8 The main body 321 has a good buffering effect. The lower end of the main body 321 is fixed to the turbine fan 3. The outer wall of the main body 321 extends outward to form an annular wrapping part 322 concentrically arranged with the main body 321. An annular limiting groove (not marked in the figure) is defined between the wrapping part 322 and the main body 321. A connecting part 17 adapted to the buffer 32 is provided on the inner wall of the housing 1. The connecting part 17 is specifically an annular rib extending downward from the inner wall of the housing 1. The lower end of the annular rib extends into the annular limiting groove to form a sealed space for buffering. When the turbine fan 3 vibrates during operation, the annular rib and the buffer 32 cooperate to compress the air in the sealed space, thereby achieving a vibration reduction effect. Of course, the lower end of the annular rib can also directly contact the buffer 32 to achieve a vibration reduction effect by relying on the elastic material of the buffer 32 itself. Of course, the main body 321 can also be a solid column (such as...). Figure 3 and Figure 4 ).

[0055] In one embodiment of this application, the buffer member 32 is a solid column shape. A connecting portion 17, adapted to the buffer member 32, is located on the inner wall of the housing 1. Specifically, the connecting portion 17 is a receiving groove formed by the downward extension of the inner wall of the housing 1. The receiving groove is a hollow column shape with an open lower end, and its shape and size match the buffer member 32. The lower end of the buffer member 32 is fixed to the turbine fan 3, and the upper end of the buffer member 32 extends into the receiving groove to form a sealed space for buffering. This structure allows the receiving groove to restrict the buffer member 32, preventing the vibration generated by the turbine fan 3 during operation from causing the buffer member 32 to shift left or right. This ensures that when the turbine fan 3 is operating, the buffer member 32 can be longitudinally positioned between the housing 1 and the turbine fan 3, compressing the air in the sealed space to achieve a better vibration reduction effect. Alternatively, the upper end of the buffer member 32 can directly contact the inner wall of the housing 1, relying on the elastic material of the buffer member 32 itself to achieve the vibration reduction effect. In another embodiment, the columnar buffer 32 in the previous embodiment can be replaced with a spring. The position of the spring is defined by the receiving groove, while the upper end of the spring contacts the inner wall of the housing 1 and the lower end of the spring contacts the turbine fan 3. The upper end and / or the lower end of the spring are fixed, and the vibration reduction effect is achieved by relying on the elasticity of the spring.

[0056] For further details, please refer to Figures 1-8 , Figure 13 The turbine box device also includes an air outlet adapter 33 for connecting the air outlet 31 of the turbine fan 3 with the second open end 12. The air outlet adapter 33 is installed inside the second open end 12, and one end of the air outlet adapter 33 bends outward to cover the end of the second open end 12, while the other end of the air outlet adapter 33 is sleeved on the air outlet 31 of the turbine fan 3.

[0057] Specifically, the air outlet adapter 33 is provided with an annular protrusion 331 adapted to the air outlet 31 of the turbine fan 3 and a circular ring 332 for contacting the inner wall of the housing 1. A buffer gap 336 is left between the circular ring 332 and the annular protrusion 331. A pressure sampling interface 18 is provided on the pipe located at the second opening end 12 on the housing 1. The air outlet adapter 33 is provided with a third connecting opening 333 for the pipe at the second opening end 12 to connect with the pressure sampling interface 18. This allows for timely detection of the gas pressure at the second opening end 12, so that the user can adjust the inlet pressure at the first opening end 11 in a timely manner. It should be noted that the detection and feedback of gas pressure is prior art, and will not be described in detail here.

[0058] In this application, the annular protrusion 331 corresponds to the annular groove 334 formed on the inner wall of the air outlet adapter 33. An annular end face (not shown in the figure) extends outward from the end of the air outlet 31 of the turbine blower 3. The annular groove 334 wraps around the outer side of the annular end face to realize the connection between the air outlet adapter 33 and the air outlet 31 of the turbine blower 3. One end of the air outlet adapter 33 is bent and extended to form a U-shaped structure 335. The U-shaped structure 335 covers the end of the second opening end 12 to realize the connection between the air outlet adapter 33 and the second opening end 12. The air outlet adapter 33 can be made of silicone. The air outlet adapter 33 is installed in the pipe of the second opening end 12. The two ends of the air outlet adapter 33 are softly connected to the second opening end 12 of the housing 1 and the air outlet 31 of the turbine blower 3, respectively, while tightly fitting together to seal the gas flow channel and ensure that the gas flow channel is in one-way flow. In one embodiment of this application, one side of the ring 332 on the air outlet adapter 33 contacts the inner wall of the housing 1, and there is a buffer gap 336 between the other side of the ring 332 on the air outlet adapter 33 and the annular protrusion 331. When the turbine fan 3 vibrates during operation, the buffer gap 336 allows the turbine fan 3 to have a certain degree of freedom of movement along the direction of the air outlet 31, which can play a role in buffering and vibration reduction.

[0059] For further details, please refer to Figures 1-13 The turbine housing assembly also includes a housing 7 for mounting the housing 1. The housing 7 has an air supply port 71 adapted to the first opening end 11. An air inlet adapter 26 is provided on the separator 2, embedded in the first opening end 11 to connect the air supply port 71 to the first channel 51. The air supply port 71 is provided with sound-absorbing cotton 72 to filter the gas and prevent dust and impurities from entering the turbine housing assembly. Furthermore, the end of the U-shaped structure 335 fits against the inner wall of the housing 7. The housing 7 has an air outlet pipe 74 with open ends, coaxially arranged with the air outlet adapter 33 to ensure smooth gas flow from the turbine housing assembly. Further, the outer wall of the turbine fan 3 has a first abutment portion 34, and the inner wall of the receiving collar 24 has a second abutment portion 241 that mates with the first abutment portion 34. When the turbine fan 3 is mounted on the receiving collar 24, the first abutment portion 34 and the receiving collar 24... The second abutment 241 is offset to limit the turbine fan 3 when it is working, thereby preventing the vibration generated by the turbine fan 3 when it is working from affecting the alignment of the outlet adapter 33 and the outlet pipe 74. Specifically, in this application, there are 12 first abutment parts 34 and 6 second abutment parts 241. Two adjacent first abutment parts 34 are provided between two adjacent second abutment parts 241, and the two adjacent first abutment parts 34 abut against the sides of the two adjacent second abutment parts 241.

[0060] For further details, please refer to Figure 1 , Figures 9-12The upper end of the outer casing 7 is provided with a top cover 10. The casing 1, which houses the turbine fan 3, is placed inside the outer casing 7. The side wall of the outer casing 7 located at the air supply port 71 extends inward to form an extension 73. An installation groove 721 for installing sound-absorbing cotton 72 is formed between the extension 73 and the outer casing 7. The sound-absorbing cotton is held in place by the installation groove 721 to prevent the sound-absorbing cotton 72 from being sucked into the first channel 51 when the turbine fan 3 is working. At the same time, the sound-absorbing cotton 72 is placed close to the air supply port 71, which is convenient for users to replace in time. This improves the problem of poor long-term use effect and inconvenient replacement of sound-absorbing cotton 72 in the prior art. The extension 73 is also provided with The air intake adapter 26 has a first fitting groove 731, a first fitting part 261 adapted to the first fitting groove 731 on the front end face, a second fitting groove 111 at the first opening end 11, and a second fitting part 262 adapted to the second fitting groove 111 on the rear end face. The air intake adapter 26 is connected to the outer shell 7 and the housing 1 by fitting and the connection is sealed so that the air supply port 71 is connected to the first opening end 11, ensuring the smooth flow of gas and the single flow direction, and reducing the noise of the turbine box device at the first opening end 11 to a certain extent.

[0061] This application also provides a ventilator including a turbine box device. The ventilator using the turbine box device of this application occupies less space and reduces noise during operation.

[0062] In summary, the present invention provides a turbine housing device and a ventilator. The turbine housing device includes: a housing, a partition disposed within the housing, and a turbine fan disposed on the partition. The partition divides the housing into a communicating upper cavity and a lower cavity. A guide structure is provided within the lower cavity, dividing the lower cavity into a first channel and a second channel. The upper cavity connects the first channel and the second channel. The first channel is located on one side of the second channel, and the second channel surrounds the axis of the turbine fan's air inlet. The housing has a first opening end communicating with the first channel and a second opening end communicating with the turbine fan's air outlet. The turbine fan's air inlet communicates with the second channel to drive gas flow between the first opening end and the second opening end. This application achieves a miniaturized design of the turbine housing device by combining the upper and lower cavities. By placing the first and second channels in the lower cavity and connecting them through the upper cavity, a longer gas passage is achieved within a smaller volume, significantly reducing the wind noise generated during turbine fan operation.

[0063] It is understood that those skilled in the art can make equivalent substitutions or modifications to the technical solution and inventive concept of the present invention, and all such substitutions or modifications should fall within the protection scope of the appended claims.
