[0052] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0053] Hereinafter, the fresh air component 100 according to an embodiment of the present invention will be described with reference to the accompanying drawings.

[0054] like Figure 1-Figure 20 As shown, the fresh air component 100 according to an embodiment of the present invention includes: a shell assembly 1, a valve 2 and a gear 3, the shell assembly 1 defines a fresh air flow channel 14; the valve 2 is rotatably installed on the shell assembly 1, and is rotatable between an open position and a closed position, and the blocking area of ​​the fresh air flow channel 14 by the valve 2 in the closed position is larger than the blocking area of ​​the fresh air flow channel 14 in the open position; the gear 3 is movably installed on the shell assembly 1, and is switchable between a stop state and an avoidance state, the valve 2 rotated to the closed position cooperates with the stop of the gear 3 switched to the stop state to jointly cut off the fresh air flow channel 14, and the blocking area of ​​the fresh air flow channel 14 by the gear 3 in the avoidance state is smaller than the blocking area of ​​the fresh air flow channel 14 in the stop state.

[0055] As a result, the gear position 3 can be changed to the avoidance state to avoid the fresh air flow channel 14, thereby increasing the maximum flow area of ​​the fresh air flow channel 14, which is beneficial to increasing the air volume of the fresh air component 100 and improving the practicality of the fresh air component 100.

[0056] For example, refer to Figure 1-Figure 9As shown, the fresh air component 100 includes a housing assembly 1 and a valve 2. The housing assembly 1 defines a fresh air flow channel 14, and the fresh air flow channel 14 is used to communicate with the outdoor space so that the outdoor fresh air can flow into the fresh air flow channel 14. The housing assembly 1 is equipped with a valve 2, and the valve 2 is configured to be rotatable relative to the housing assembly 1, so that the valve 2 can be switched between an open position and a closed position, and the blocking area of ​​the fresh air flow channel 14 by the valve 2 in the closed position is greater than the blocking area of ​​the fresh air flow channel 14 in the open position. For example, when the valve 2 is rotated to the closed position, the valve 2 can be perpendicular to the axial direction of the fresh air flow channel 14, and when the valve 2 is rotated to the open position, the valve 2 can be arranged to extend along the axial direction of the fresh air flow channel 14.

[0057] Among them, the fresh air component 100 also includes a gear 3, which is movably mounted on the housing assembly 1, and the gear 3 is configured to be switchable between a stop state and an avoidance state. Specifically, after the gear 3 is switched to the stop state, the gear 3 can extend into the fresh air flow channel 14 and be opposite to the valve 2. At this time, if the valve 2 is rotated to the closed position, the valve 2 can cooperate with the gear 3 to achieve limit, and the valve 2 can also cooperate with the gear 3 to jointly cut off the fresh air flow channel 14; and when the gear 3 is switched to the avoidance state, at least part of the gear 3 can be staggered with the fresh air flow channel 14, so that the shielding area of ​​the fresh air flow channel 14 by the gear 3 in the avoidance state is smaller than the shielding area of ​​the fresh air flow channel 14 in the stop state. At this time, if the valve 2 is rotated to the open position, the fresh air flow channel 14 is fully opened.

[0058] It can be understood that when the valve 2 is rotated to the closed position and the gear 3 is changed to the stop position 3, the valve 2 and the gear 3 can cooperate to completely cut off the fresh air flow channel 14, and when the valve 2 is rotated to the open position and the gear 3 is changed to the open position, the valve 2 and the gear 3 can avoid the fresh air flow channel 14 to the maximum extent, so that the flow area of ​​the fresh air flow channel 14 is larger.

[0059] According to the fresh air component 100 of the embodiment of the present invention, the gear position 3 can be switched between the stop state and the avoidance state, so that the gear position 3 can be switched to the avoidance state to avoid the fresh air flow channel 14, thereby increasing the maximum flow area of ​​the fresh air flow channel 14, which is beneficial to increasing the air intake volume of the fresh air component 100 and improving the practicality of the fresh air component 100.

[0060] In some embodiments of the present invention, the valve 2 is linked with the gear 3 so that when the valve 2 rotates to the open position, the linkage gear 3 is changed to the avoidance state, and when the valve 2 rotates to the closed position, the linkage gear 3 is changed to the stop state.

[0061] For example, the valve 2 can be linked with the gear 3, such as directly connecting the valve 2 with the gear 3 power, or connecting the same driving member with the valve 2 and the gear 3 power respectively, so that the fresh air component 100 can drive the valve 2 and the gear 3 to move synchronously. Figure 4 As shown, when the valve 2 is rotated to the open position, the valve 2 can be linked with the gear 3 to change to the avoidance state, so that the valve 2 and the gear 3 can open the fresh air flow channel 14; Figure 7 As shown, when the valve 2 rotates to the closed position, the valve 2 can be linked with the gear 3 to change to the stop state, so that the valve 2 can cooperate with the gear 3 to cut off the fresh air flow channel 14. Through the above arrangement, the number of driving parts can be reduced, which is conducive to reducing costs and layout difficulties, and the stability of the fresh air component 100 during the switching process can be improved, thereby improving the reliability of the fresh air component 100.

[0062] In some embodiments of the present invention, the fresh air flow channel 14 includes a port 111, the valve 2 is rotatably disposed at the port 111, the rotation axis of the valve 2 extends radially along the port 111, the gear 3 extends along the edge of the port 111 and defines a retractable gap 32, and the gap 32 becomes larger when the gear 3 is in the avoidance state relative to the stop state, so that the gear 3 reduces the obstruction of the port 111.

[0063] For example, refer to Figure 4-Figure 9 As shown, the fresh air flow channel 14 includes a port 111, and the valve 2 is rotatably disposed at the port 111, and the rotation axis of the valve 2 is arranged along the radial direction of the port 111, so that the valve 2 can rotate around the radial direction of the port. When the valve 2 is rotated to the closed position, the valve 2 can be perpendicular to the axis of the port 111 to block the fresh air flow channel 14, and when the valve 2 is rotated to the open position, the valve 2 can be parallel to the radial direction of the port 111 to avoid the fresh air flow channel 14.

[0064] Among them, Figure 4-Figure 9 As shown, the gear 3 can be constructed in a ring shape, the gear 3 is arranged along the edge of the port 111, the gear 3 is a deformable structure, and a retractable notch 32 is defined on one side of the gear 3. When the gear 3 is changed to the avoidance state, the gear 3 is deformed radially outward to enlarge the notch 32, and at least part of the gear 3 can be moved out of the fresh air flow channel 14 to avoid the fresh air flow channel 14; and when the gear 3 is changed to the stop state, the gear 3 can be deformed radially inward to reduce the notch 32, and at least part of the gear 3 can be moved into the fresh air flow channel 14, and the gear 3 located in the fresh air flow channel 14 can stop and cooperate with the valve 2 to cut off the fresh air flow channel 14.

[0065] Through the above arrangement, the structure of the fresh air component 100 is simplified, the layout difficulty is reduced, and the operating stability of the fresh air component 100 can be improved, which is beneficial to improving the practicality of the fresh air component 100.

[0066] In some embodiments of the present invention, the gear 3 has two movable ends 31b, and the gap 32 is defined between the two movable ends 31b. The valve 2 cooperates with the two movable ends 31b so that when the valve 2 rotates to the open position, the two movable ends 31b are linked to separate to make the gap 32 larger. When the valve 2 rotates to the closed position, the two movable ends 31b are linked to move closer to make the gap 32 smaller.

[0067] For example, refer to Figure 6 and Fig. 9 As shown, the gear 3 has two movable ends 31b, which are arranged opposite to each other to define a gap 32, and at least a portion of the valve 2 is located in the gap 32 and cooperates with the two movable ends 31b. When the valve 2 is rotated to the open position, the valve 2 can be linked with the two movable ends 31b to separate, so that the gap 32 becomes larger, and at least a portion of the gear 3 can be moved out of the fresh air flow channel 14 to avoid the fresh air flow channel 14; and when the valve 2 is rotated to the closed position, the valve 2 can be linked with the two movable ends 31b to move closer, so that the gap 32 becomes smaller, and at least a portion of the gear 3 can be moved into the fresh air flow channel 14 to block the fresh air flow channel 14.

[0068] Through the above-mentioned setting, the valve 2 can drive the gear 3 to change, which is beneficial to reduce the number of driving parts, reduce costs and layout difficulty, and can improve the switching stability of the fresh air component 100, which is beneficial to improve the reliability of the fresh air component 100.

[0069] In some embodiments of the present invention, the gear 3 includes two movable gears 31, which are respectively arranged on both sides of the rotation axis of the valve 2. The movable gear 31 extends along the edge of the port 111 and one end in the extension direction is a positioning end 31a that is positioned and matched with the shell assembly 1, and the other end in the extension direction is a movable end 31b.

[0070] For example, refer to Figure 6 , Fig. 9 and Fig.10 As shown, the gear 3 includes two movable gears 31, and the two movable gears 31 are respectively arranged on both sides of the rotation axis of the valve 2. The movable gears 31 are both constructed in an arc shape. The two movable gears 31 are respectively extended along the edge of the port 111 and formed into a ring. One end of the movable gear 31 in the extension direction is set as a positioning end 31a, and the positioning end 31a is used for positioning and cooperating with the shell assembly 1 so that the movable gear 31 can be rotatably installed on the shell assembly 1, and the other end of the movable gear 31 in the extension direction is set as a movable end 31b, and the movable end 31b is used to link with the valve 2 to rotate around the positioning end 31a.

[0071] In the specific working process, when the valve 2 rotates to the open position, the valve 2 can link the two active gears 31 to move around the positioning end 31a in the direction away from each other, so that the gap 32 becomes larger, and at least part of the gear 3 can be moved out of the fresh air flow channel 14 to avoid the fresh air flow channel 14; and when the valve 2 rotates to the closed position, the valve 2 can link the two active gears 31 to move around the positioning end 31a in the direction close to each other, so that the gap 32 becomes smaller, and at least part of the gear 3 can be moved into the fresh air flow channel 14 to block the fresh air flow channel 14.

[0072] It can be understood that by dividing the gear 3 into two active gears 31, the two active gears 31 can cooperate with the valve 2 respectively, which reduces the processing difficulty and layout difficulty of the gear 3, and improves the coordination stability between the valve 2 and the gear 3, which is beneficial to improving the reliability of the fresh air component 100.

[0073] In some embodiments of the present invention, the valve 2 has a rotating part at both ends, and the rotating part is rotatably connected to the shell assembly 1. The two rotating parts are respectively a first rotating part 21 and a second rotating part 22. The first rotating part 21 is located between the positioning ends 31a of the two active gears 31, and the second rotating part 22 is located between the active ends 31b of the two active gears 31, and the second rotating part 22 is linked to the two active ends 31b.

[0074] For example, refer to Figure 4-Figure 6 As shown, a rotating part can be provided at both ends of the valve 2 along the rotation axis, and the rotating part is used to be rotatably connected to the housing assembly 1. For example, the rotating part can be constructed as a rotating shaft, and a shaft hole 33 is correspondingly provided on the housing assembly 1, so that the rotating shaft can be rotatably matched with the shaft hole 33; or, the rotating part can be constructed as a shaft hole 33, and a rotating shaft is correspondingly provided on the housing assembly 1, so that the rotating shaft can be rotatably matched with the shaft hole 33, and the present invention is not limited to this.

[0075] The two rotating parts are respectively a first rotating part 21 and a second rotating part 22. The first rotating part 21 is located between the positioning ends 31a of the two active gears 31. The first rotating part 21 is used to be connected to the driving member by power, so that the driving member can drive the valve 2 to rotate through the first rotating part 21. The second rotating part 22 is located between the active ends 31b of the two active gears 31. The second rotating part 22 is used to be linked with the two active ends 31b to achieve the linkage between the valve 2 and the gear 3. Through the above arrangement, the valve 2 and the active gear 31 can be in the same plane, which is conducive to saving space, reducing the difficulty of layout, and improving the reliability of the fresh air component 100.

[0076] It should be noted that if Figure 4As shown, the rotation axis of the valve 2 can be set to extend vertically, the first rotating part 21 can be set at the upper end of the valve 2, the first rotating part 21 is used to be connected to the driving member, and the second rotating part 22 is set at the lower end of the valve 2, and the second rotating part 22 is used to be linked with the two movable ends 31b. In this way, the difficulty of installation and maintenance can be reduced, and the design rationality of the fresh air component 100 is improved.

[0077] In some embodiments of the present invention, the second rotating portion 22 is connected to each movable end 31b through a pull rod 4 respectively. When the valve 2 is rotated to the open position, the second rotating portion 22 pushes the two movable ends 31b away from each other through the two pull rods 4 to enlarge the gap 32. When the valve 2 is rotated to the closed position, the second rotating portion 22 pulls the two movable ends 31b closer together through the two pull rods 4 to reduce the gap 32.

[0078] For example, refer to Figure 4-Figure 9 As shown, the second rotating part 22 can be provided with a tie rod 4 on both opposite sides along the radial direction, one end of the tie rod 4 is connected to the second rotating part 22 and the other end is connected to the movable end 31b on the corresponding side, and the second rotating part 22 can be connected to the movable end 31b through the tie rod 4 to realize the linkage between the valve 2 and the movable gear 31. In the specific working process, when the valve 2 is rotated to the open position, the two sides of the tie rod 4 of the second rotating part 22 can move to the position opposite to the movable end 31b, so that the two tie rods 4 can push the two movable ends 31b outward away from each other, so that the gap 32 becomes larger; and when the valve 2 is rotated to the closed position, the two sides of the tie rod 4 of the second rotating part 22 can move to the position staggered with the movable end 31b, so that the two tie rods 4 can pull the two movable ends 31b close to each other, so that the gap 32 becomes smaller.

[0079] Through the above arrangement, the matching stability between the second rotating part 22 and the movable end 31b can be improved, and the structural complexity of the fresh air component 100 can be reduced, which is conducive to reducing costs.

[0080] In some embodiments of the present invention, the first connection portion 23 extends from both radial sides of the second rotating portion 22, and the second connection portion 311 extends from the movable end 31b in a direction away from the port 111. The two ends of the pull rod 4 respectively have rings 41, so as to be rotatably connected to the first connection portion 23 and the second connection portion 311 through the rings 41 at both ends.

[0081] For example, refer to Figure 6As shown, first connecting parts 23 may be provided on both sides of the second rotating part 22 in the radial direction, the first connecting parts 23 protrude outward in the radial direction, a first connecting hole is formed on the first connecting part 23, and a second connecting part 311 may be provided on the movable end 31b, the second connecting part 311 extends in a direction away from the port 111, and a second connecting hole is formed on the second connecting part 311. At the same time, collars 41 may be provided on both ends of the pull rod 4 in the length direction, one of the two collars 41 is used to connect to the first connecting hole of the first connecting part 23 and the other is used to connect to the second connecting hole of the second connecting part 311, so that the pull rod 4 can connect the second rotating part 22 with the movable end 31b.

[0083] In some embodiments of the present invention, the two movable ends 31b are connected by an elastic member 5, and a pushing portion 24 is provided on the second rotating portion 22. When the valve 2 rotates to the open position, the pushing portion 24 rotates with the second rotating portion 22 to the expanded position to push the two movable ends 31b away from each other so that the elastic member 5 is stretched and the gap 32 becomes larger. When the valve 2 rotates to the closed position, the pushing portion 24 leaves the expanded position with the second rotating portion 22, and the elastic member 5 contracts to pull the two movable ends 31b closer together so that the gap 32 becomes smaller.

[0084] For example, refer to Figure 11-Figure 15 As shown, a connection seat 313 can be provided on the same side of the two movable ends 31b, respectively.

At the same time, a pushing portion 24 can be provided on the second rotating portion 22. The pushing portion 24 is used to cooperate with the movable ends 31b, so that the second rotating portion 22 can selectively drive the two movable ends 31b to move away from each other through the pushing portion 24.

[0085] In the specific working process, when the valve 2 rotates to the open position, the push part 24 can rotate to the open position with the second rotating part 22. At this time, the push part 24 can push the two movable ends 31b away to make the gap 32 larger and the elastic member 5 stretched; and when the valve 2 rotates to the closed position, the push part 24 can leave the open position with the second rotating part 22, the push part 24 is out of contact with the movable end 31b, and the elastic member 5 contracts to pull the two movable ends 31b closer to make the gap 32 smaller. Through the above arrangement, the reset reliability of the gear 3 can be improved, the failure rate of the fresh air component 100 can be reduced, and the reliability of the fresh air component 100 can be improved.

Through the above arrangement, the reset stability of the gear position 3 can be improved, so that the gear position 3 is not easily deformed or stuck, and the reliability of the fresh air component 100 is improved.

[0087] In some embodiments of the present invention, a matching portion 312 is provided on the movable end 31b, and the pushing portion 24 extends along the radial direction of the second rotating portion 22 to the radial sides of the second rotating portion 22, and the pushing portion 24 pushes the movable end 31b through the matching portion 312, wherein at least one of the matching portion 312 and the pushing portion 24 has a guide surface 314, and during the process of the valve 2 rotating from the closed position to the open position, the pushing portion 24 pushes the matching portion 312 through the guide surface 314.

[0088] For example, refer to Fig.13 As shown, two pushing portions 24 can be provided on the second rotating portion 22, and the two pushing portions 24 are provided on both radial sides of the second rotating portion 22, and the pushing portions 24 are constructed to protrude radially outward to the radial outer side of the second rotating portion 22, and a matching portion 312 is provided on the movable end 31b, the matching portion 312 is arranged opposite to the pushing portion 24, and the pushing portion 24 can push the movable end 31b to move through the matching portion 312 to move the two movable ends 31b away from each other.

[0089] Among them, a guide surface 314 can be provided on at least one of the matching portion 312 and the pushing portion 24, such as a guide surface 314 can be provided on the matching portion 312, or a guide surface 314 can be provided on the pushing portion 24; or, guide surfaces 314 can be provided on the pushing portion 24 and the matching portion 312, respectively, and the present invention does not limit this. In this way, when the valve 2 rotates from the closed position to the open position, the pushing portion 24 can push the matching portion 312 to move through the guide surface 314 to drive the two movable ends 31b away. In this way, the smoothness of the gear 3 switching state can be improved, which is conducive to improving the reliability of the fresh air component 100.
