Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, and in particular to a refrigerator and a fluid flow path regulating component. Background Technology

[0002] The refrigerator is equipped with air ducts. The fan delivers the cooling air from the cooling chamber to each storage compartment through the air ducts. In order to control the cooling air in the air ducts, fluid flow path adjustment components are often installed in the air ducts.

[0003] Currently, common fluid flow regulation components in refrigerators typically use baffles at various flow inlets. By controlling the rotation of these baffles, the opening and closing of multiple flow paths can be controlled. This type of fluid flow regulation component occupies a large space, has a complex design, and is prone to damage. Summary of the Invention

[0004] In view of this, the main technical problem solved by the present invention is to provide a refrigerator and a fluid flow path adjustment component, which can easily realize the adjustment of the flow path by cooperating with the cavity through an adjustment component, which occupies little space and is not easily damaged.

[0005] To address the aforementioned technical problems, this application provides a fluid flow path adjustment component, including a cavity, an adjusting member, and a driving member. The cavity has an inner cavity with an air inlet and an air outlet communicating with it. The adjusting member is disposed within the inner cavity and includes at least a first plate and a second plate. The first and second plates are connected and form an included angle, dividing the inner cavity into at least a first space and a second space. The driving member drives the adjusting member to rotate, causing a change in the relative positional relationship between the first space and the second space within the inner cavity relative to the air inlet and air outlet. This relative positional relationship corresponds at least to a change in the size of the connecting channel between the air outlet, the first space, and the air inlet in sequence, or a change in the size of the connecting channel between the air outlet, the second space, and the air inlet in sequence.

[0006] In one embodiment of this application, the inner cavity is a cylindrical inner cavity, and the edges of at least the first plate and the second plate are in contact with the cavity wall of the cylindrical inner cavity. The remaining portions of at least the first plate and the second plate, excluding the edges, are spaced apart from the corresponding cavity walls of the cylindrical inner cavity, so as to divide the inner cavity into at least a first space and a second space.

[0007] In one embodiment of this application, the air inlet direction intersects the central axis of the cylindrical inner cavity.

[0008] In one embodiment of this application, the cavity is a hexahedron, and the axis of the cylindrical inner cavity is perpendicular to the first and second faces opposite to each other on the hexahedron. At least the first and second plates are identical in shape and size, both being rectangular plates. One side of each of the first and second plates is connected, and the other side of each of the first and second plates is connected to the circular sidewall of the cylindrical inner cavity. The remaining sides of the first and second plates are connected to the two end walls of the cylindrical inner cavity. An air inlet is located on the third face of the hexahedron, and an air outlet is located on at least the fourth face of the hexahedron.

[0009] In one embodiment of this application, the number of air outlets is at least two, and they are respectively disposed on the fourth and fifth faces of the hexahedron.

[0010] In one embodiment of this application, the number of air outlets is at least three, and they are respectively disposed on the fourth, fifth, and sixth faces of the hexahedron.

[0011] In one embodiment of this application, the number of air outlets is four: a first air outlet located on the fourth side, a second air outlet located on the fifth side, a third air outlet located on the sixth side, and a fourth air outlet located on the second side. A driving member is fixed to the first side of the hexahedron.

[0012] In one embodiment of this application, the adjusting member is composed of a first plate and a second plate, with an included angle of no more than 90 degrees. The first plate and the second plate form a first space with the cylindrical inner cavity within the included angle, and the remaining space of the cylindrical inner cavity is a second space.

[0013] In one embodiment of this application, the relative positional relationship includes at least the connection between the air inlet and the first space and the fourth air outlet, or the connection between the air inlet and the second space, the second air outlet and the third air outlet, or the connection between the air inlet and the second space, the first air outlet and the third air outlet, or the connection between the air inlet and the second space, the first air outlet and the second air outlet.

[0014] In one embodiment of this application, the number of air outlets is at least two, and they are respectively disposed on the fourth face and the second face of the hexahedron, with the air outlet on the second face being smaller than the air outlet on the fourth face.

[0015] In one embodiment of this application, the air outlet on the second side is located in the adjacent air inlet area of ​​the second side, and when the first plate and the second plate are rotated to the corresponding relative position relationship, the air inlet is connected to the first space, and the air outlet on the second side is connected.

[0016] In one embodiment of this application, the included angle between the first plate and the second plate is 90±60 degrees.

[0017] In one embodiment of this application, the edge of the air inlet protrudes outward from the cavity.

[0018] In one embodiment of this application, the driving member is capable of driving the adjusting member to rotate 360 ​​degrees.

[0019] To address the aforementioned technical problems, another technical solution adopted in this application is to provide a refrigerator, including a cabinet, a cold source, and the fluid flow path regulating component described in any of the above embodiments. The cabinet has at least one storage space. The cold source is disposed within the cabinet and has an air outlet for outputting cooling air. The fluid flow path regulating component is disposed within the cabinet, with an air inlet connected to the air outlet, and the air outlet connected to the storage space.

[0020] To address the aforementioned technical problems, another technical solution adopted in this application is to provide a fluid flow path adjustment assembly, including a cavity, an adjusting member, and a driving member. The cavity has a cylindrical inner cavity, and the cavity has a first air inlet and at least two second air inlets communicating with the cylindrical inner cavity. The adjusting member is rotatably disposed within the cylindrical inner cavity. The edge of the adjusting member is in contact with the cavity wall of the cylindrical inner cavity, and the remaining portion of the adjusting member, excluding the edge, is spaced apart from the corresponding cavity wall of the cylindrical inner cavity, thereby dividing the cylindrical inner cavity into at least a first space and a second space. The corresponding cavity walls of the first space and the second space have different sizes. The driving member is used to drive the adjusting member to rotate, causing the first space and the second space to switch between at least a first relative positional relationship and a second relative positional relationship between the cylindrical inner cavity and the first air inlet and the second air inlet. The first relative positional relationship corresponds to the first air inlet, the first space / second space, and one second air inlet being sequentially connected. The second relative positional relationship corresponds to the first air inlet, the first space / second space, and another second air inlet being connected.

[0021] The beneficial effects of this invention are as follows: Unlike the prior art, this application uses an adjusting member to divide the inner cavity into at least a first space and a second space. During rotation, the relative positional relationship between the first space and the second space in the inner cavity relative to the air inlet and air outlet can change. Thus, by using an adjusting member in conjunction with the cavity, the flow path can be easily adjusted, occupying little space and not easily damaged. Attached Figure Description

[0033] Please see Figure 1 and Figure 2 , Figure 1 This is a schematic diagram from an angle of one embodiment of the fluid flow path adjustment component of this application. Figure 2 This is a schematic diagram from another angle of an embodiment of the fluid flow path adjustment component of this application.

[0034] In this embodiment, the fluid flow path regulating component is installed in the refrigerator's air duct to control the cooling air within the duct. The fluid flow path regulating component includes a cavity 1, an regulating component 2, and a driving component 3.

[0035] The cavity 1 has an inner cavity 4, and the cavity 1 has an air inlet 11 and an air outlet communicating with the inner cavity 4. The air inlet 11 can be connected to a duct that outputs cooling air. Cooling air enters the inner cavity 4 of the cavity 1 through the air inlet 11 and flows out through the air outlet of the cavity 1. The air outlet can be directly connected to the refrigerator storage compartment, or it can be connected to a duct to deliver cooling air to the target storage compartment. The number of air inlets and outlets 11 can be set according to actual needs.

[0036] Please refer to the following: Figure 3 , Figure 3 This is a cross-sectional view of an embodiment of the fluid flow path regulating component of this application.

[0037] The adjusting member 2 is disposed in the inner cavity 4. The adjusting member 2 includes at least a first plate 7 and a second plate 8. The first plate 7 and the second plate 8 are connected and form an included angle 9. The first plate 7 and the second plate 8 divide the inner cavity 4 into at least a first space 5 and a second space 6.

[0038] The driving component 3 drives the adjusting component 2 to rotate, causing a change in the relative positional relationship between the first space 5 and the second space 6 within the inner cavity 4 relative to the air inlet 11 and the air outlet. This relative positional relationship corresponds at least to a change in the size of the connecting channel between the air outlet, the first space 5, and the air inlet 11, or a change in the size of the connecting channel between the air outlet, the second space 6, and the air inlet 11. Specifically, the driving end of the driving component 3 is fixedly connected to the adjusting component 2, controlling the rotation of the adjusting component 2 within the cavity 1, thereby changing the relative positional relationship between the first space 5 and the second space 6 relative to the cavity 1. When the adjusting component 2 rotates, the air outlet and the air inlet 11 are connected through either the first space 5 or the second space 6, and the sizes of the air inlet 11 and the air outlet continuously change. Optionally, when the adjusting component 2 stops rotating, the air inlet 11, the first space 5, and the air outlet are connected in sequence, or the air outlet, the second space 6, and the air inlet 11 are connected in sequence.

[0039] In some embodiments, the inner cavity 4 is a cylindrical inner cavity 4, with at least the edges of the first plate 7 and the second plate 8 in contact with the cavity wall of the cylindrical inner cavity 4, and at least the remaining portions of the first plate 7 and the second plate 8, excluding their edges, spaced apart from the corresponding cavity walls of the cylindrical inner cavity 4, thereby dividing the inner cavity 4 into at least a first space 5 and a second space 6. Exemplarily, the edges of the first plate 7 and the second plate 8 being in contact with the cavity wall of the cylindrical inner cavity 4, dividing the cylindrical inner cavity 4 into the first space 5 and the second space 6, ensures good airtightness of the air duct, preventing free airflow within the first space 5 and the second space 6.

[0040] In some application scenarios, in order to achieve control of more flow paths, the number of plates can be increased, dividing the cylindrical inner cavity 4 into more spaces, and connecting them with different spaces through the air inlet 11, the air outlet, and forming more flow paths.

[0041] In some embodiments, the air inlet 11 is oriented in a direction that intersects the central axis of the cylindrical inner cavity 4. Specifically, the air from the air inlet 11 can be blown into the cylindrical inner cavity 4 perpendicular to its central axis. The drive member 3 drives the adjustment member 2 to rotate around the central axis of the cylindrical inner cavity 4, thereby changing the air outlet or the air volume.

[0042] Please see Figure 4 , Figure 4 This is a schematic diagram of an embodiment of the fluid flow path adjustment component of this application, omitting cavity 1.

[0043] In some embodiments, the cavity 1 is a hexahedron, and the axis of the cylindrical inner cavity 4 is perpendicular to the first face 21 and the second face 22 opposite to each other of the hexahedron. At least the first plate 7 and the second plate 8 are identical in shape and size, both being rectangular plates. One side of each of the first plate 7 and the second plate 8 is connected, and the other side of each of the first plate 7 and the second plate 8 is connected to the circular sidewall of the cylindrical inner cavity 4. The remaining sides of the first plate 7 and the second plate 8 are connected to the two end walls of the cylindrical inner cavity 4. An air inlet 11 is disposed on the third face 23 of the hexahedron, and an air outlet is disposed at least on the fourth face 24 of the hexahedron. Exemplarily, the first plate 7 and the second plate 8 are symmetrical about the axis of the cylindrical inner cavity 4. The other side of each of the first plate 7 and the second plate 8 is connected to the circular sidewall of the cylindrical inner cavity 4, and the remaining side of the first plate 7 and the second plate 8 is connected to the two end walls of the cylindrical inner cavity 4, so that the cross-section of the first space 5 and the second space 6 into which the cylindrical inner cavity 4 is divided is fan-shaped and the axis of symmetry is perpendicular to the axis of the cylindrical inner cavity 4.

[0044] Please see Figure 5 . Figure 5 This is a cross-sectional view of four positional relationships of the regulating member 2 in one embodiment of the fluid flow path regulating assembly of this application.

[0045] In some embodiments, such as Figure 2 As shown, an air inlet 11 is provided on the third face 23 of the hexahedron, and an air outlet is provided on the fourth face 24. The size and shape of the air outlet and the air inlet 11 can be the same or different, depending on the actual situation. In the first position relationship 41, the airflow of the regulating member 2 is sealed within the first space 5. In the second position relationship 42, the airflow of the regulating member 2 is sealed within the second space 6. At this time, the air outlet and the air inlet 11 cannot be connected, and a flow path cannot be formed. In the third position relationship 43 and the fourth position relationship 44, the air outlet, the air inlet 11 on the fourth face 24 and the second space 6 are connected sequentially, and the airflow flows out from the air outlet on the fourth face 24, forming a flow path.

[0046] In some embodiments, the number of air outlets is at least two, and they are respectively disposed on the fourth face 24 and the fifth face 25 of the hexahedron. For example, the number of air outlets is two, and they are disposed on the fourth face 24 and the fifth face 25 of the hexahedron.

[0047] When the regulating component 2 is in the first position relationship 41, the airflow is sealed within the first space 5, and the air outlet and air inlet 11 cannot be connected, thus failing to form a flow path.

[0048] When the adjusting member 2 is in the second position relationship 42, the air inlet 11, the air outlet on the fifth surface 25, and the second space 6 are connected in sequence, and the airflow flows out from the air outlet on the fifth surface 25 to form a flow path.

[0049] When the adjusting component 2 is in the third position relationship 43, the air inlet 11, the air outlet on the fourth surface 24, and the second space 6 are connected in sequence, and the airflow flows out from the air outlet on the fourth surface 24 to form a flow path.

[0050] When the adjusting component 2 is in the fourth position relationship 44, the air inlet 11, the air outlet on the fourth surface 24, the air outlet on the fifth surface 25, and the second space 6 are connected in sequence, and the airflow flows out from the air outlets on the fourth surface 24 and the fifth surface 25 at the same time, forming a flow path.

[0051] In some embodiments, the number of air outlets is at least three, and they are respectively disposed on the fourth face 24, the fifth face 25, and the sixth face 26 of the hexahedron. For example, the number of air outlets is three, and they are disposed on the fourth face 24, the fifth face 25, and the sixth face 26 of the hexahedron.

[0052] When the adjusting component 2 is in the first position relationship 41, the air outlet and air inlet 11 cannot be connected, and the airflow is sealed in the first space 5, and a flow path cannot be formed.

[0053] When the adjusting member 2 is in the second position relationship 42, the air inlet 11, the air outlet on the fifth surface 25, the air outlet on the sixth surface 26, and the second space 6 are connected in sequence, and the airflow flows out from the air outlets on the fifth surface 25 and the sixth surface 26 to form a flow path.

[0054] When the adjusting component 2 is in the third position relationship 43, the air inlet 11, the air outlet on the fourth surface 24, the air outlet on the sixth surface 26, and the second space 6 are connected in sequence, and the airflow flows out from the air outlets on the fourth surface 24 and the sixth surface 26 to form a flow path.

[0055] When the adjusting component 2 is in the fourth position relationship 44, the air inlet 11, the air outlet on the fourth surface 24, the air outlet on the fifth surface 25, and the second space 6 are connected in sequence, and the airflow flows out from the air outlets on the fourth surface 24 and the fifth surface 25 to form a flow path.

[0056] In some embodiments, the number of air outlets is four: a first air outlet 31 disposed on the fourth surface 24, a second air outlet 32 ​​disposed on the fifth surface 25, a third air outlet 33 disposed on the sixth surface 26, and a fourth air outlet 34 disposed on the second surface 22. A driving member 3 is fixed to the first surface 21 of the hexahedron. Exemplarily, when the driving member 3 on the first surface 21 drives the adjusting member 2 to a first position relationship 41, the air inlet 11, the fourth air outlet 34 on the second surface 22, and the first space 5 are sequentially connected, and airflow flows out from the fourth air outlet 34, forming a flow path.

[0057] In some embodiments, the adjusting member 2 is composed of a first plate 7 and a second plate 8, with an included angle 9 not exceeding 90 degrees. The first plate 7 and the second plate 8 form a first space 5 with the cylindrical inner cavity 4 within the included angle 9, and the remaining space of the cylindrical inner cavity 4 is a second space 6. Preferably, the adjusting member 2 is composed of a first plate 7 and a second plate 8, with an included angle 9 of 90 degrees. Since the cavity 1 is hexahedral and has three air outlets all located on a surface parallel to the axis of the cylindrical inner cavity 4, when the included angle 9 of the adjusting member 2 is 90 degrees, it can completely cover the air outlets or air inlets 11 on the surface parallel to the axis of the cylindrical inner cavity 4.

[0058] In some embodiments, the relative positional relationship includes at least the connection between the air inlet 11 and the first space 5 and the fourth air outlet 34, or the connection between the air inlet 11 and the second space 6, the second air outlet 32 ​​and the third air outlet 33, or the connection between the air inlet 11 and the second space 6, the first air outlet 31 and the third air outlet 33, or the connection between the air inlet 11 and the second space 6, the first air outlet 31 and the second air outlet 32.

[0059] For example, such as Figure 5 As shown, when the adjusting member 2 is in the first position relationship 41, the air inlet 11, the fourth air outlet 34, and the first space 5 are connected in sequence, and the airflow flows out from the fourth air outlet 34 to form a flow path.

[0060] When the adjusting component 2 is in the second position relationship 42, the air inlet 11, the second air outlet 32, the third air outlet 33, and the second space 6 are connected in sequence, and the airflow flows out from the second air outlet 32 ​​and the third air outlet 33 to form a flow path.

[0061] When the adjusting component 2 is in the third position relationship 43, the air inlet 11, the first air outlet 31, the third air outlet 33, and the second space 6 are connected in sequence, and the airflow flows out from the first air outlet 31 and the third air outlet 33 to form a flow path.

[0062] When the adjusting component 2 is in the fourth position relationship 44, the air inlet 11, the first air outlet 31, the second air outlet 32, and the second space 6 are connected in sequence, and the airflow flows out from the first air outlet 31 and the second air outlet 32 ​​to form a flow path.

[0063] Of course, the relative positions can also include, for example, stopping when the first plate 7 and the second plate 8 of the adjusting member 2 are rotated to the middle position between the air inlet 11 and the first air outlet 31. At this time, the air inlet 11, the first space 5, the first air outlet 31, and the fourth air outlet 34 are connected, and the air inlet 11, the second space 6, the second air outlet 32, the third air outlet 33, and the fourth air outlet 34 are connected. The airflow flows out from the first air outlet 31, the second air outlet 32, the third air outlet 33, and the fourth air outlet 34, forming a flow path.

[0064] In one embodiment, the relative positions include the first plate 7 and the second plate 8 of the adjusting member 2 rotating to the middle position of the first air outlet 31 and the second air outlet 32 ​​and stopping. At this time, the air inlet 11, the first space 5, the first air outlet 31, and the second air outlet 32 ​​are connected, and the air inlet 11, the second space 6, the second air outlet 32, the third air outlet 33, and the fourth air outlet 34 are connected. The airflow flows out from the first air outlet 31, the second air outlet 32, the third air outlet 33, and the fourth air outlet 34, forming a flow path.

[0065] In one embodiment, the relative positions include, for example, stopping when the first plate 7 and the second plate 8 of the adjusting member 2 are rotated to the middle position between the second air outlet 32 ​​and the third air outlet 33. At this time, the air inlet 11, the first space 5, the second air outlet 32, and the third air outlet 33 are connected, and the air inlet 11, the second space 6, the first air outlet 31, the second air outlet 32, and the fourth air outlet 34 are connected. The airflow flows out from the first air outlet 31, the second air outlet 32, the third air outlet 33, and the fourth air outlet 34, forming a flow path.

[0066] In one embodiment, the relative positions include the first plate 7 and the second plate 8 of the adjusting member 2 rotating to the middle position between the third air outlet 33 and the air inlet 11 and stopping. At this time, the air inlet 11, the first space 5, the fourth air outlet 34, and the third air outlet 33 are connected, and the air inlet 11, the second space 6, the first air outlet 31, the second air outlet 32, and the fourth air outlet 34 are also connected. The airflow flows out from the first air outlet 31, the second air outlet 32, the third air outlet 33, and the fourth air outlet 34, forming a flow path.

[0067] In some embodiments, the number of air outlets is at least two, and they are respectively disposed on the fourth face 24 and the second face 22 of the hexahedron, with the air outlet on the second face 22 being smaller than the air outlet on the fourth face 24. For example, the number of air outlets is two, and they are respectively disposed on the fourth face 24 and the second face 22 of the hexahedron, with the air outlet on the second face 22 being smaller than the air outlet on the fourth face 24.

[0068] When the adjusting member 2 is in the first position relationship 41, the air outlet, air inlet 11, and first space 5 on the second surface 22 are connected in sequence, and the airflow flows out from the air outlet of the second surface 22, forming a flow path. At this time, the air outlet and air inlet 11 on the fourth surface 24 cannot be connected.

[0069] When the adjusting member 2 is in the second position relationship 42, the air outlet, air inlet 11, and second space 6 on the second surface 22 are connected in sequence, and the airflow flows out from the air outlet of the second surface 22, forming a flow path. At this time, the air outlet and air inlet 11 on the fourth surface 24 cannot be connected.

[0070] When the adjusting component 2 is in the third position relationship 43, the air inlet 11, the air outlet on the fourth surface 24, and the second space 6 are sequentially connected, and the airflow flows out from the air outlet on the fourth surface 24, forming a flow path. At this time, the air outlet on the second surface 22, the air inlet 11, and the second space 6 are sequentially connected. However, since the second surface 22 is perpendicular to the plane where the air inlet 11 is located, and the area of ​​the air outlet on the second surface 22 is smaller than that of the air outlet on the fourth surface 24, the fluid pressure drop is relatively high. The fluid will flow in the direction of the lower pressure, so most of the airflow flows out from the air outlet on the fourth surface 24, and the amount of gas flowing out from the air outlet on the second surface 22 is negligible.

[0071] When the adjusting component 2 is in the fourth position relationship 44, the air inlet 11, the air outlet on the fourth surface 24, and the second space 6 are sequentially connected, and the airflow flows out from the air outlet on the fourth surface 24, forming a flow path. At this time, although the air outlet on the second surface 22, the air inlet 11, and the second space 6 are sequentially connected, because the fluid pressure drop is relatively high, most of the airflow flows out from the air outlet on the fourth surface 24, and the amount of gas flowing out from the air outlet on the second surface 22 is negligible.

[0072] In some embodiments, the air outlet on the second surface 22 is located in the region adjacent to the air inlet 11 on the second surface 22, and when the first plate 7 and the second plate 8 are rotated to the position where the air inlet 11 communicates with the first space 5, the air inlet 11 communicates with the air outlet on the second surface 22. Specifically, the air outlet on the second surface 22 is fan-shaped, and the angle of the fan is the same as the angle 9 between the first plate 7 and the second plate 8 of the adjusting member 2. When the adjusting member 2 is in the first position relationship 41, the air inlet 11, the air outlet on the second surface 22, and the first space 5 are connected, and the airflow flows out from the air outlet on the second surface 22, forming a flow path.

[0073] In some embodiments, the included angle 9 between the first plate 7 and the second plate 8 is 90±60 degrees. Depending on the area of ​​the air outlet, the included angle 9 between the first plate 7 and the second plate 8 is 90±60 degrees, such that after the other side of each of the first plate 7 and the second plate 8 is in contact with the circular sidewall of the cylindrical inner cavity 4, the projected area facing the air outlet is larger than the area of ​​the air outlet.

[0074] In some embodiments, such as Figure 2 As shown, the edge of the air inlet 11 protrudes outward from the cavity 1. Specifically, the air duct is tightly connected to the protruding edge of the air inlet 11, which improves the efficiency of cold air transmission in the air duct and also facilitates installation. Similarly, the edge of the air outlet can also protrude outward from the cavity 1 to facilitate connection with the duct, through which cold air is delivered to the refrigerator storage compartment.

[0075] In some embodiments, the drive element 3 can drive the adjustment element 2 to rotate 360 ​​degrees. This improves the working efficiency of the fluid flow path adjustment assembly, allowing the drive element 3 to drive the adjustment element 2 to reach the preset position more quickly.

[0076] To address the aforementioned technical problems, another technical solution adopted in this application is to provide a refrigerator, including a cabinet, a cold source, and the fluid flow path regulating component described in any of the above embodiments. The cabinet has at least one storage space. The cold source is disposed within the cabinet and has an air outlet to output cooling air. The fluid flow path regulating component is disposed within the cabinet, with an air inlet 11 connected to the air outlet, and the air outlet connected to the storage space. In one application scenario, the refrigerator has multiple storage spaces, requiring more flow paths. Two fluid flow path regulating components can be assembled together, with the air inlets 11 of the two components connected to the air outlet of the cold source, and the air outlets connected to different storage spaces, forming more flow paths to deliver cold air to the storage spaces.

[0077] To address the aforementioned technical problems, another technical solution adopted in this application is to provide a fluid flow path adjustment assembly, including a cavity 1, an adjustment component 2, and a driving component 3. The cavity 1 has a cylindrical inner cavity 4, and the cavity 1 has a first air inlet communicating with the cylindrical inner cavity 4 and at least two second air inlets. Exemplarily, the two second air inlets can be configured as air inlets 11, and the first air inlet as an air outlet. Similarly, the first air inlet can be configured as an air inlet 11, and the two second air inlets as air outlets. The number of second air inlets can be increased according to actual needs.

[0078] An adjusting member 2 is rotatably disposed within a cylindrical inner cavity 4. The edge of the adjusting member 2 is in contact with the cavity wall of the cylindrical inner cavity 4, and the remaining portion of the adjusting member 2, excluding the edge, is spaced apart from the corresponding cavity wall of the cylindrical inner cavity 4, thereby dividing the cylindrical inner cavity 4 into at least a first space 5 and a second space 6. The corresponding cavity walls of the first space 5 and the second space 6 are of different sizes. A driving member 3 is used to drive the adjusting member 2 to rotate, causing the first space 5 and the second space 6 to switch between at least a first relative position relationship and a second relative position relationship between the cylindrical inner cavity 4 and the first air vent and the second air vent. The first relative position relationship corresponds to the first air vent, the first space 5 / second space 6, and one second air vent being sequentially connected. The second relative position relationship corresponds to the first air vent, the first space 5 / second space 6, and another second air vent being connected. Specifically, the driving end of the driving member 3 is fixedly connected to the adjusting member 2, controlling the adjusting member 2 to rotate within the cavity 1, thereby changing the relative position relationship between the first space 5 and the second space 6 relative to the cavity 1. When the adjusting component 2 rotates, the air outlet and the air inlet 11 are connected through the first space 5 or the second space 6, and the sizes of the air inlet 11 and the air outlet continuously change. Optionally, when the adjusting component 2 stops rotating, the first air outlet, the first space 5 and the second air outlet are connected, or the first air outlet, the second space 6 and the second air outlet are connected, forming different flow paths.

[0079] In this embodiment, the first air inlet is the air inlet 11, and the two second air inlets are air outlets.

[0080] For example, the adjusting member 2 can be composed of an arc-shaped plate. The edge of the arc-shaped plate is in contact with the cavity wall of the cylindrical inner cavity 4, and the remaining part of the arc-shaped plate, excluding the edge, is spaced apart from the corresponding cavity wall of the cylindrical inner cavity 4. The arc-shaped plate divides the cylindrical inner cavity 4 into a first space 5 and a second space 6. After the airflow enters the cylindrical inner cavity 4 from the air inlet 11, it cannot flow freely between the first space 5 and the second space 6.

[0081] Cavity 1 can be a hexahedron or a cylinder, etc. The following description uses a hexahedron as an example.

[0082] The first air inlet, 11, is located on the third face 23 of the hexahedron. Two second air inlets are located on the fourth face 24 and the second face 22 of the hexahedron, respectively. The second air inlet on the second face 22 is positioned such that, when the adjusting member 2 is in the first position relationship 41, the adjusting member 2 is in contact with the second face 22 of the hexahedron, forming a contour. The shape of the second air inlet is the shape enclosed by this contour. The second air inlet on the second face 22 is smaller than the second air inlet on the third face 23.

[0083] like Figure 5 As shown, when the adjusting member 2 is in the first position relationship 41, the first air outlet, the first space 5, and the second air outlet on the second surface 22 are connected, and the airflow flows out from the second air outlet on the second surface 22 to form a flow path.

[0084] When the adjusting component 2 is in the second position relationship 42, the first air outlet, the second space 6, and the second air outlet on the second surface 22 are connected, and the airflow flows out from the second air outlet on the second surface 22 to form a flow path.

[0085] When the adjusting component 2 is in the third position relationship 43, the first air vent, the second space 6, and the two second air vents are connected, and the airflow flows out from the two second air vents to form a flow path.

[0086] When the adjusting component 2 is in the fourth position relationship 44, the first air vent, the second space 6, and the two second air vents are connected, and the airflow flows out from the two second air vents to form a flow path.

[0087] Since the second face 22 of the hexahedron is perpendicular to the plane of the first air inlet, and the first air inlet is the air inlet 11, the airflow blows in perpendicularly to the second face 22, resulting in a higher fluid pressure drop on the second face 22. The fluid will flow in the direction of the lower pressure drop. When the adjusting member 2 is in the third position relationship 43 and the fourth position relationship 44, the amount of gas flowing out of the second air inlet on the second face 22 is negligible, and most of the gas flows out from the second air inlet on the fourth face 24.

[0088] Depending on the actual situation, the second air vent on the second surface 22 can be set at different positions on the second surface 22. For example, the second air vent on the second surface 22 can be set when the adjusting member 2 is in the second position relationship 42, where the adjusting member 2 is connected to the hexahedral second surface 22 and forms a contour. The shape of the second air vent is the shape enclosed by this contour.

[0089] When the adjusting element 2 is in the first position relationship 41, the airflow flows into the first space 5 of the inner cavity 4 and is blocked from the second air outlet, so that no flow path can be formed.

[0090] When the adjusting member 2 is in the second position relationship 42, the airflow flows into the second space 6 of the inner cavity 4 and is blocked from the second air outlet, so that no flow path can be formed.

[0091] When the adjusting component 2 is in the third position relationship 43, the first air vent, the second space 6, and the two second air vents are connected. Since the fluid will flow in the direction of pressure drop, the amount of gas flowing out of the second air vent on the second surface 22 is negligible, and most of the gas flows out from the second air vent on the fourth surface 24.

[0092] When the adjusting element 2 is in the fourth position relationship 44, the first air vent, the second space 6, and the two second air vents are connected. Since the fluid will flow in the direction of the pressure drop, the amount of gas flowing out of the second air vent on the second surface 22 is negligible, and most of the gas flows out from the second air vent on the fourth surface 24.

[0093] For example, when the adjusting member 2 is in the third position relationship 43, the second air vent on the second face 22 is positioned so that the adjusting member 2 is in contact with the second face 22 of the hexahedron and forms a contour. The shape of the second air vent is the shape enclosed by this contour.

[0094] When the adjusting element 2 is in the first position relationship 41, the airflow flows into the first space 5 of the inner cavity 4 and is blocked from the second air outlet, so that no flow path can be formed.

[0095] When the adjusting component 2 is in the second position relationship 42, the first air outlet, the second space 6, and the second air outlet on the second surface 22 are connected, and the airflow flows out from the second air outlet on the second surface 22 to form a flow path.

[0096] When the adjusting component 2 is in the third position relationship 43, the first air vent, the second space 6, and the second air vent on the fourth surface 24 are connected, and the airflow flows out from the second air vent on the fourth surface 24 to form a flow path.

[0097] When the adjusting element 2 is in the fourth position relationship 44, the first air vent, the second space 6, and the two second air vents are connected. Since the fluid will flow in the direction of the pressure drop, the amount of gas flowing out of the second air vent on the second surface 22 is negligible, and most of the gas flows out from the second air vent on the fourth surface 24.

[0098] For example, when the adjusting member 2 is in the fourth position relationship 44, the second air vent on the second surface 22 is positioned so that the adjusting member 2 is in contact with the second surface 22 of the hexahedron and forms a contour. The shape of the second air vent is the shape enclosed by this contour.

[0099] At this time, when the adjusting member 2 is in the first position relationship 41, the airflow flows into the first space 5 of the inner cavity 4 and is blocked from the second air outlet, so that no flow path can be formed.

[0100] When the adjusting component 2 is in the second position relationship 42, the first air outlet, the second space 6, and the second air outlet on the second surface 22 are connected, and the airflow flows out from the second air outlet on the second surface 22 to form a flow path.

[0101] When the adjusting component 2 is in the third position relationship 43, the first air vent, the second space 6, and the two second air vents are connected. Since the fluid will flow in the direction of pressure drop, the amount of gas flowing out of the second air vent on the second surface 22 is negligible, and most of the gas flows out from the second air vent on the fourth surface 24.

[0102] When the adjusting component 2 is in the fourth position relationship 44, the first air vent, the second space 6, and the second air vent on the fourth surface 24 are connected, and the airflow flows out from the second air vent on the fourth surface 24 to form a flow path.
