[0017] In one embodiment, the housing further has a wind guiding plate and a reset member, the first end of the wind guiding plate is installed on the first housing and is hinged to the first housing, the second end of the wind guiding plate abuts against the first housing through the reset member, and the wind guiding plate is located at the first air outlet; the opening direction of the wind guiding plate faces towards the outside of the first housing;

[0018] The cross section of the first housing is L-shaped, the first housing has an L-shaped installation groove, the first air outlet is located on one side of the installation groove, and the second air outlet is located on the other side of the installation groove.

[0019] In one embodiment, the first housing includes a first connecting plate and four second connecting plates. The four second connecting plates are respectively installed around the first connecting plate, and the second connecting plates are perpendicular to the first connecting plate.

[0020] The first air outlet has two openings. One opening is provided on the first connecting plate, and the other opening is provided on the second connecting plate. The exhaust directions of the two openings intersect. Each opening has the air guide plate, and the opening directions of the two air guide plates of the two openings are opposite.

[0021] In one embodiment, the fan mechanism includes a second driving member and a blade. The second driving member is installed in the third housing of the outer shell, the blade is sleeved outside the second driving member, and the air suction surface of the blade faces the air inlet.

[0022] The technical solution provided by the present utility model has the following advantages and effects:

[0023] 1. By providing a first air outlet, a second air outlet and an air inlet on the outer shell, the air circulation system has two exhaust channels. Among them, the air inlet is used to form a first exhaust channel with the second air outlet, and the air inlet is used to form a second exhaust channel with the air duct and the first air outlet. During installation, the air circulation system can be installed on the outer wall, with the first air outlet of the air circulation system facing the indoor, and the second air outlet of the air circulation system facing the outdoor; moreover, the fan mechanism is installed inside the outer shell, and the fan mechanism is located between the air inlet and the first air outlet or the second air outlet. The wind shield is movably arranged on the outer shell and is located at the second air outlet or the air duct; during use, the wind shield can be adjusted to have a first moving position and a second moving position. In the first moving position, the wind shield closes the second air outlet, so that the air sucked by the fan mechanism is discharged from the air duct and the first air outlet in sequence, thereby realizing the indoor air internal circulation; in the second moving position, the air duct is closed by the wind shield. After the air duct is closed, the air in the outer shell cannot be discharged from the first air outlet through the air duct. At this time, the second air outlet is in an open state, so that the air is discharged from the second air outlet, thereby realizing the indoor air external circulation.

[0024] 2. To further achieve automatic control of the position of the wind deflector, an adjustment assembly is provided. The first driving member of the adjustment assembly provides power to drive the screw to rotate. Since a sliding sleeve is sleeved outside the screw and is in threaded cooperation with the sliding sleeve, the sliding sleeve is connected to the wind deflector through an adjusting member. The adjusting member is used to restrict the sliding sleeve to prevent the sliding sleeve from rotating with the screw. When the screw rotates, it drives the sliding sleeve to move back and forth in the axial direction of the screw axis. The sliding sleeve drives the adjusting member to move. Since the adjusting member is hinged to the wind deflector, the adjusting member drives the wind deflector to move, enabling the wind deflector to have a first moving position and a second moving position. The switching between the first moving position and the second moving position can be achieved by controlling the first driving member to rotate clockwise and counterclockwise, realizing automatic control of the position of the wind deflector and switching the internal and external circulation of the indoor air according to user needs.

[0025] 3. To improve the flexibility of the wind deflector when moving, the first end of the wind deflector is rotatably fitted with the housing, and the second end of the wind deflector is used to abut against the inner wall of the housing. When the wind deflector is opened, the second air outlet is opened. When the second air outlet is fully opened, the wind deflector will move to the second moving position to close the air duct. In this way, the second air outlet and the air duct can be closed or opened by the wind deflector. Moreover, by providing a push block and a sliding shaft on the inner side of the wind deflector, the sliding shaft is installed outside the push block and is located in the chute. The adjusting member is rotatably fitted with the adjusting member through the chute. When the adjusting member moves backward, the sliding shaft moves in the chute. At this time, the wind deflector opens the second air outlet. As the sliding shaft moves from the bottom of the chute to the top of the chute, the second air outlet is fully opened at this time, and the wind deflector closes the air duct to realize the external circulation of the indoor air. By moving the sliding shaft in the chute, the flexibility of the wind deflector when moving is improved.

[0026] 4. To further achieve the closing or opening of the second air outlet or the air duct by the wind deflector, the housing includes a first housing, a second housing, and a third housing. The first air outlet is provided on the outer wall of the first housing, and the second air outlet is provided on the outer wall of the second housing. The first housing is sleeved outside the third housing to form an air duct. This air duct is located between the first air outlet and the second air outlet. When the wind deflector closes the air duct, when the width of the wind deflector is greater than the width of the air duct, the second end of this wind deflector is used to abut against the third housing. When the width of the wind deflector is equal to the width of the air duct, the second end of the wind deflector contacts the outer wall of the third housing to close the air duct. By cleverly setting the connection relationship between the first housing, the second housing, and the third housing, only by controlling the position of the wind deflector, the closing or opening of the second air outlet or the air duct by the wind deflector is further achieved, saving the components of the air circulation system.

[0027] 5. To improve the air flow inside the housing, the rear cover is set to be convex, and the convex direction of the rear cover faces the air guiding channel, so that the surface of the rear cover facing the air guiding channel is in a convex conical shape, and the cross-section of the air guiding channel near the rear cover is V-shaped. After the air enters the air guiding channel and encounters the blocking of the conical rear cover, the air will flow towards the periphery of the housing along the guidance of the conical surface and flow out from the second air outlet or the first air outlet, thereby further improving the air flow inside the housing.

[0028] 6. To purify the indoor air, a negative ion electrode is provided inside the shielding cover, a negative ion generator is installed inside the housing, and the negative ion generator is electrically connected to the negative ion electrode; when the air circulation system starts the indoor circulation, the second air outlet is closed by the wind deflector, the negative ion generator is started, the negative ion electrode generates negative ions, and when the fan mechanism sucks air, it will suck the negative ions near the shielding cover and discharge them from the air duct and the first air outlet. Negative ions have the function of adsorbing dust, thereby purifying the indoor air. The negative ion electrode is provided inside the shielding cover, and the multiple bars of the shielding cover have a certain protective effect, thus reducing the phenomenon that the negative ion electrode is damaged by the external environment.

[0029] 7. To guide the exhaust direction of the first air outlet, the housing further has a wind deflector. The first end of the wind deflector is hinged to the first housing, and the second end of the wind deflector abuts against the first housing through a reset member. The wind deflector is located at the first air outlet, and its opening direction faces outside the first housing; this wind deflector forms a shield on one side of the first air outlet and is used to guide the exhaust direction of the air flow at the first air outlet, preventing the air from diffusing at the first air outlet, so that the air flows towards the specified direction under the action of the wind deflector. After the wind deflector closes the air duct, the wind deflector is reset through the reset member, thereby closing the first air outlet and improving the sealing performance of the air circulation system.

[0030] 8. To increase the air flow rate of the first air outlet and further restrict the exhaust direction of the first air outlet, the first housing includes a first connecting plate and a second connecting plate, and the first air outlet has two openings, which are respectively arranged on the first connecting plate and the second connecting plate, increasing the opening area of the first air outlet, thereby increasing the air flow rate of the first air outlet. Moreover, each opening has the above-mentioned wind deflector. When the wind deflector closes the second air outlet, the air flow flows through the air duct to the two openings, generating pressure and pushing open the wind deflectors of the two openings. Since the opening directions of the two wind deflectors are opposite, after the wind deflectors are pushed open, the two wind deflectors form a shield and restriction on both sides of the first air outlet, thereby further restricting the exhaust direction of the first air outlet and guiding the air flow towards a specific direction.

[0031] 9. The second driving member drives the blades to rotate. As the blades rotate, they suck in the air at the air inlet. During the process of the air circulation system exhausting air outward, the air pressure inside the housing drops, the air inside the housing becomes thinner, forming a negative pressure area. Due to the air pressure difference, the air compensates and flows into the housing, thereby further realizing the external air circulation and internal air circulation in the room.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0041] For the convenience of understanding the present utility model, specific embodiments of the present utility model will be described in more detail below with reference to the accompanying drawings of the specification.

[0042] Unless otherwise specified or defined, the "first, second..." used herein is only for distinguishing names and does not represent a specific quantity or order.

[0043] Unless otherwise specified or defined, the term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0044] It should be noted that "fixed to" and "connected to" herein can be directly fixed or connected to an element, or indirectly fixed or connected to an element.

[0045] As Figures 1 to 5As shown, an air circulation system 100 includes a housing 1, a fan mechanism 4, and a wind deflector 121. The housing 1 has a first air outlet 15, a second air outlet 16, and an air inlet 18. A wind channel 17 is formed inside the housing 1. The air inlet 18 is communicated with the first air outlet 15 through the wind channel 17, and the air inlet 18 is communicated with the second air outlet 16. The fan mechanism 4 is installed inside the housing 1, and the fan mechanism 4 is located between the air inlet 18 and the second air outlet 16. The wind deflector 121 is located at the second air outlet 16 or in the wind channel 17 and is movably arranged on the housing 1. The wind deflector 121 has a first moving position and a second moving position. In the first moving position, the wind deflector 121 closes the second air outlet 16, and the air inlet 18, the wind channel 17, and the first air outlet 15 are communicated in sequence. In the second moving position, the wind channel 17 is closed by the wind deflector 121, and the air inlet 18 and the second air outlet 16 are communicated. By providing the first air outlet 15, the second air outlet 16, and the air inlet 18 on the housing 1, the air circulation system 100 has two exhaust channels. Among them, the air inlet 18 is used to form a first exhaust channel with the second air outlet 16, and the air inlet 18 is used to form a second exhaust channel with the wind channel 17 and the first air outlet 15. During installation, the air circulation system 100 can be installed on an exterior wall, with the first air outlet 15 of the air circulation system 100 facing indoors and the second air outlet 16 of the air circulation system 100 facing outdoors. Moreover, the fan mechanism 4 is installed inside the housing 1, and the fan mechanism 4 is located between the air inlet 18 and the second air outlet 16. By movably arranging the wind deflector 121 on the housing 1 and locating it at the second air outlet 16 or in the wind channel 17. During use, the position of the wind deflector 121 can be adjusted to make the wind deflector 121 have a first moving position and a second moving position. In the first moving position, the wind deflector 121 closes the second air outlet 16, so that the air sucked by the fan mechanism 4 is discharged from the wind channel 17 and the first air outlet 15 in sequence, thereby realizing the internal air circulation in the room. In the second moving position, the wind channel 17 is closed by the wind deflector 121. After the wind channel 17 is closed, the air in the housing 1 cannot be discharged from the first air outlet 15 through the wind channel 17. At this time, the second air outlet 16 is in an open state, and the air is discharged from the second air outlet 16, thereby realizing the external air circulation in the room.

[0046] In order to further realize the automatic control of the position of the wind deflector 121. As Figures 4 to 6As shown, the air circulation system 100 further includes an adjustment component 43. The adjustment component 43 includes a first driving member 431, a screw 432, a sliding sleeve 434, and an adjustment member 433. The first driving member 431 is installed on the housing 1, the screw 432 is installed on the output end of the first driving member 431, the sliding sleeve 434 is sleeved outside the screw 432 and is in threaded cooperation with the outer wall of the screw 432; the first end of the adjustment member 433 is installed outside the sliding sleeve 434, and the second end of the adjustment member 433 is hinged to the wind deflector 121. By providing the adjustment component 43, the first driving member 431 of the adjustment component 43 provides power to drive the screw 432 to rotate. Since the sliding sleeve 434 is sleeved outside the screw 432 and is in threaded cooperation with the sliding sleeve 434, the sliding sleeve 434 is connected to the wind deflector 121 through the adjustment member 433, and the adjustment member 433 is used to limit the sliding sleeve 434 to prevent the sliding sleeve 434 from rotating with the screw 432. Since the rotation of the sliding sleeve 434 is restricted, through the circumferential force applied by the screw 432, during the rotation of the screw 432, the sliding sleeve 434 is driven to move back and forth in the axial direction of the screw 432, and the sliding sleeve 434 drives the adjustment member 433 to move; since the adjustment member 433 is hinged to the wind deflector 121, the adjustment member 433 is used to drive the wind deflector 121 to move, so that the wind deflector 121 has a first moving position and a second moving position. In the switching between the first moving position and the second moving position, it can be achieved by controlling the first driving member 431 to rotate clockwise and counterclockwise, realizing the automatic control of the position of the wind deflector 121 and switching the internal circulation and external circulation of the indoor air according to the user's needs.

[0047] As Figure 3 and Figure 7 shown, the first end of the wind deflector 121 is rotatably engaged with the housing 1, the second end of the wind deflector 121 is used to abut against the inner wall of the housing 1, and the opening direction of the wind deflector 121 faces the inside of the housing 1; by rotatably engaging the first end of the wind deflector 121 with the housing 1, the second end of the wind deflector 121 is used to abut against the inner wall of the housing 1; when the wind deflector 121 is opened, the second air outlet 16 is opened, and when the second air outlet 16 is fully opened, the wind deflector 121 will move to the second moving position, thereby closing the air duct 17; thus arranged, the second air outlet 16 and the air duct 17 can be closed or opened by the wind deflector 121.

[0048] To improve the flexibility of the wind deflector 121 during movement. In addition, the adjusting member 433 has a chute 4333 which extends along the length of the adjusting member 433. The inner side of the wind deflector 121 has a push block 122 and a sliding shaft 123. The sliding shaft 123 is installed outside the push block 122, and at least part of the sliding shaft 123 is located in the chute 4333 and is rotatably engaged with the adjusting member 433. Moreover, by providing the push block 122 and the sliding shaft 123 on the inner side of the wind deflector 121, the sliding shaft 123 is installed outside the push block 122 and is located in the chute 4333, and the adjusting member 433 is rotatably engaged with the adjusting member 433 through the chute 4333; when the adjusting member 433 moves backward, the sliding shaft 123 moves in the chute 4333, and at this time the wind deflector 121 opens the second air outlet 16. As the sliding shaft 123 moves from the bottom of the chute 4333 to the top of the chute 4333, the second air outlet 16 is fully opened, and the wind deflector 121 closes the air duct 17 to realize the external circulation of indoor air; by the sliding shaft 123 moving in the chute 4333, the flexibility of the wind deflector 121 during movement is improved.

[0049] In addition, the adjusting member 433 includes a first moving rod 4331 and a second moving rod 4332. Both the first moving rod 4331 and the second moving rod 4332 are installed outside the sliding sleeve 434, and the first moving rod 4331 and the second moving rod 4332 are arranged oppositely; the first moving rod 4331 and the second moving rod 4332 are respectively used to connect the wind deflectors 121 at the top and bottom of the housing 1, so as to synchronously adjust the wind deflectors 121 around the housing 1.

[0050] To further realize the wind deflector 121 closing or opening the second air outlet 16 or the air duct 17. As Figures 3 to 5As shown in the figure, the outer shell 1 includes a first housing 11, a second housing 12, and a third housing 19. The second housing 12 is installed at the rear end of the first housing 11. A first air outlet 15 is provided on the outer wall of the first housing 11, and a second air outlet 16 is provided on the outer wall of the second housing 12. The first housing 11 is sleeved outside the third housing 19. A wind channel 17 is formed between the side wall of the first housing 11 and the outer wall of the third housing 19. The wind channel 17 is located between the first air outlet 15 and the second air outlet 16. The width of the wind deflector 121 is greater than or equal to the width of the wind channel 17. A wind guiding channel 192 is formed inside the third housing 19. The wind guiding channel 192 communicates with the wind channel 17. The fan mechanism 4 is located inside the wind guiding channel 192. This wind channel 17 is located between the first air outlet 15 and the second air outlet 16. When the wind deflector 121 closes the wind channel 17, when the width of the wind deflector 121 is greater than the width of the wind channel 17, the second end of this wind deflector 121 is used to abut against the third housing 19. When the width of the wind deflector 121 is equal to the width of the wind channel 17, the second end of the wind deflector 121 contacts the outer wall of the third housing 19, thereby closing the wind channel 17. By cleverly setting the connection relationship between the first housing 11, the second housing 12, and the third housing 19, only by controlling the position of the wind deflector 121, the wind deflector 121 can be further used to close or open the second air outlet 16 or the wind channel 17, saving the components of the air circulation system 100.

[0051] In this embodiment, an installation plate 191 is further provided inside the third housing 19. The installation plate 191 is perpendicular to the first housing 11. The first driving member 431 and the second driving member 41 are respectively installed on both sides of the installation plate 191.

[0052] To improve the fluidity of air inside the outer shell 1. As Figures 3 to 5 shown, the second housing 12 has a rear cover 14. The rear cover 14 is convex. The convex direction of the rear cover 14 faces the wind guiding channel 192, so that the cross-section of the wind guiding channel 192 close to the rear cover 14 is V-shaped. By setting the rear cover 14 to be convex and the convex direction of the rear cover 14 facing the wind guiding channel 192, the surface of the rear cover 14 facing the wind guiding channel 192 is in a convex conical shape. A vertex angle 141 is formed at the convex position of the rear cover 14. The vertex angle 141 is arranged close to the end of the screw 432. The cross-section of the wind guiding channel 192 close to the rear cover 14 is V-shaped. After the air enters the wind guiding channel 192, it is blocked by the conical rear cover 14, and the air will flow along the guide of the conical surface towards the surrounding of the outer shell 1 and flow out from the second air outlet 16 or the first air outlet 15, thereby further improving the fluidity of air inside the outer shell 1.

[0053] To purify the indoor air. As Figure 1 and Figure 4As shown, the air circulation system 100 further includes a shielding cover 13, an ion generator 31, and a negative ion electrode 3. The shielding cover 13 is installed at the front end of the third housing 19, and the ion generator 31 is installed inside the first housing 11. The negative ion electrode 3 is installed inside the shielding cover 13 and is located in the air guiding channel 192. The negative ion electrode 3 is electrically connected to the ion generator 31. The shielding cover 13 has a plurality of blocking bars, which are arranged at intervals, and an air inlet 18 is formed between two adjacent blocking bars. When the air circulation system 100 starts the indoor circulation, the second air outlet 16 is closed by the wind deflector 121, the negative ion generator 31 is started, and the negative ion electrode 3 generates negative ions. When the fan mechanism 4 sucks air, it will suck the negative ions near the shielding cover 13 and discharge them from the air duct 17 and the first air outlet 15. Negative ions have the function of adsorbing dust, thereby purifying the indoor air. The negative ion electrode 3 is arranged inside the shielding cover 13, and the plurality of blocking bars of the shielding cover 13 have a certain protective effect, thereby reducing the phenomenon that the negative ion electrode 3 is damaged by the external environment.

[0054] To guide the exhaust direction of the first air outlet 15. As Figure 4 and Figure 5 shown, the housing 1 further includes a wind deflector 111 and a reset member (not shown in the figure). The reset member is a spring. The first end of the wind deflector 111 is installed on the first housing 11 and is hinged to the first housing 11. The second end of the wind deflector 111 abuts against the first housing 11 through the reset member, and the wind deflector 111 is located at the first air outlet 15. The opening direction of the wind deflector 111 faces outside the first housing 11. The wind deflector 111 forms a shield on one side of the first air outlet 15 and is used to guide the air flow direction of the first air outlet 15, avoiding the diffusion of air at the first air outlet 15, and making the air flow in a specified direction under the action of the wind deflector 111. After the wind deflector 121 closes the air duct 17, the wind deflector 111 is reset through the reset member, thereby closing the first air outlet 15 and improving the sealing performance of the air circulation system 100.

[0055] In addition, the cross-section of the first housing 11 is L-shaped. The first housing 11 has an L-shaped installation groove 114. The first air outlet 15 is located on one side of the installation groove 114, and the second air outlet 16 is located on the other side of the installation groove 114. The air circulation system 100 can be clamped on the top and bottom of the exterior wall installation opening through the installation groove 114, thereby facilitating the installation of the air circulation system 100 and making the first air outlet 15 and the second air outlet 16 located on both sides of the exterior wall respectively. The first air outlet 15 faces inside the exterior wall, and the second air outlet 16 faces outside the exterior wall, enabling the air circulation system 100 to have indoor air internal circulation and external circulation. In this embodiment, the air circulation system 100 can also be installed at the floor slab. The first air outlet 15 is used to connect the indoor exhaust duct, and the second air outlet 16 is used to connect the outdoor exhaust duct.

[0056] To increase the flow rate of the first air outlet 15 and further restrict the exhaust direction of the first air outlet 15. As Figure 1 , Figure 4 and Figure 5 shown, the first housing 11 includes a first connection plate 112 and four second connection plates 113. The four second connection plates 113 are respectively installed around the first connection plate 112, and the second connection plates 113 are perpendicular to the first connection plate 112; the first air outlet 15 has two through openings 151, one of the through openings 151 is arranged on the first connection plate 112, and the other through opening 151 is arranged on the second connection plate 113. The exhaust directions of the two through openings 151 intersect. Each through opening 151 has a wind deflector 111, and the opening directions of the two wind deflectors 111 of the two through openings 151 are opposite. By having two through openings 151 in the first air outlet 15, and the two through openings 151 are respectively arranged on the first connection plate 112 and the second connection plate 113, the opening area of the first air outlet 15 is increased, thereby increasing the flow rate of the first air outlet 15. Moreover, each through opening 151 has the wind deflector 111. When the wind deflector 121 closes the second air outlet 16, the air flow flows through the air duct 17 to the two through openings 151, the air flow generates pressure, and pushes open the wind deflectors 111 of the two through openings 151. Since the opening directions of the two wind deflectors 111 are opposite, after the wind deflectors 111 are pushed open, the two wind deflectors 111 form a shield and restriction on both sides of the first air outlet 15, thereby further restricting the exhaust direction of the first air outlet 15 and guiding the air flow to flow in a specific direction.

[0057] As Figure 4 and Figure 5 shown, the fan mechanism 4 includes a second driving member 41 and a blade 42. The second driving member 41 is installed on the mounting plate 191 of the third housing 19, and the blade 42 is sleeved outside the second driving member 41. The air suction surface of the blade 42 faces the air inlet 18. By driving the blade 42 to rotate through the second driving member 41, the blade 42 rotates to suck the air at the air inlet 18. During the process of the air circulation system 100 exhausting air outward, the air pressure inside the housing 1 will decrease, the air inside the housing 1 becomes thinner, forming a negative pressure area, and the air flows into the housing 1 due to the air pressure difference compensation, thereby further realizing the external air circulation and internal air circulation in the room.

[0058] In this embodiment, this air circulation system 100 further has a lighting strip 2. This lighting strip 2 is installed at the front end of the first housing 11 and extends along the circumferential direction of the first housing 11. When this air circulation system 100 is installed on the ceiling or the outer wall, it can be used for indoor lighting.

[0059] In this embodiment, the air circulation system 100 further includes a heating element 5, which is installed in the third housing 19 and located within the air guide channel 192. In relatively cold regions, when the air circulation system 100 turns on the indoor circulation, the heating element 5 can be turned on. The heating element 5 heats the air in the air guide channel 192, and the heated air flows through the air duct 17 to the first air outlet 15, thereby heating the indoor environment, raising the indoor temperature, and improving the indoor comfort level.

[0060] As Figures 1 to 5 shown, an operation method of an air circulation system 100 includes the following steps:

[0061] Step 1: Start the fan mechanism 4. The fan mechanism 4 sucks air from the air inlet 18, moves the wind deflector 121 to the first moving position, and closes the second air outlet 16. The air sequentially discharges from the air duct 17 and the first air outlet 15 within the housing 1.

[0062] Step 2: Move the wind deflector 121 from the first moving position to the second moving position. The air duct 17 is closed by the wind deflector 121, and the second air outlet 16 is opened. The air discharges from the second air outlet 16.

[0063] In the above operation method, the indoor air internal circulation and external circulation are achieved by adjusting the position of the wind deflector 121. Its operation method is simple, facilitating mass production and promotion.

[0064] The working principle of this air circulation device 100: The first driving member 431 drives the adjusting member 433 to move. The adjusting member 433 adjusts the position of the wind deflector 121, enabling the wind deflector 121 to have a first moving position and a second moving position. The first driving member 431 drives the screw 432 to rotate clockwise and turns on the ion generator 31. The wind deflector 121 moves to the first moving position, the wind deflector 121 closes the second air outlet 16, and the air sequentially discharges from the air duct 17 and the first air outlet 15. The negative ion electrode 3 generates negative ions to purify the indoor air and realizes the indoor air internal circulation. The first driving member 431 drives the screw 432 to rotate counterclockwise and turns off the ion generator 31. The wind deflector 121 moves to the second moving position, the wind deflector 121 closes the air duct 17, and the air discharges from the second air outlet 16, realizing the indoor air external circulation.

[0065] The above embodiments are not an exhaustive list based on the present utility model. In addition, there can be multiple other embodiments not listed. Any substitution and improvement made without violating the concept of the present utility model fall within the protection scope of the present utility model.
