As shown in fig. 1 to 7, the utility model provides a pair of driven wind deflectors, including drive assembly 4, first aviation baffle 1 and second aviation baffle 2, this drive assembly 4 includes gear drive, and gear drive includes first transmission tooth 43 and output tooth 42, and first transmission tooth 43 then includes meshing tooth section 432 and scarce tooth section 433, and meshing tooth section 432 distributes on the rotation direction of first transmission tooth 43 with scarce tooth section 433; the meshing tooth section 432 is meshed with the output tooth 42, and the tooth lacking section 433 is in rolling connection with the output tooth 42; the first air deflector 1 is synchronously connected with the first transmission gear 43; the second air deflector 2 is synchronously connected with the output tooth 42.

On the basis of the above structure, when the driven dual air guide plate of the present embodiment is used, the present embodiment takes the application of the dual air guide plate to the air outlet of the air conditioner as an example, and the dual air guide plate can be used to open or close the air outlet of the air conditioner.

In the initial assembly state, the state at this time is defined as a first state, at this time, the tooth-missing section 433 of the first transmission tooth 43 is in rolling connection with the output tooth 42, the rotation of the first transmission tooth 43 does not drive the output tooth 42 to rotate, when the first transmission tooth 43 starts to rotate, the first air deflector 1 starts to rotate synchronously, and the second air deflector 2 does not rotate along with the rotation of the first air deflector 1.

After the first transmission tooth 43 rotates to a certain angle, the meshing tooth section 432 on the first transmission tooth 43 starts to be meshed with the output tooth 42, and the state at this time is defined as a second state, at this time, along with the rotation of the first transmission tooth 43, the output tooth 42 also rotates accordingly, that is, at this time, the first air deflector 1 and the second air deflector 2 start to rotate simultaneously.

Because first transmission tooth 43 drives when first aviation baffle 1 rotates to the first position, it is specific, in this embodiment, the first position is that first aviation baffle 1 is a plane with second aviation baffle 2, first aviation baffle 1 can regard as the extension board of second aviation baffle 2, the length of air-out passageway has been prolonged in other words, to the indoor set of air conditioner, longer air-out passageway can make the air conditioner wind blow farther, cover bigger indoor space, thereby make indoor environment temperature change more obvious, the efficiency of air conditioner regulation indoor temperature has effectively been promoted, user's use experience has been improved.

According to the principle of air cold-hot circulation, the density of cold air is higher than that of air at normal temperature, the outlet air is blown upwards during refrigeration, and the cold air sinks to cool the whole room; the density of the hot air is lower than that of the air at normal temperature, the air is properly blown downwards during heating, and the hot air rises, so that the temperature of the whole room is raised.

Therefore, in this embodiment, in order to enable the air conditioner to better achieve the cooling and heating functions, the air conditioner main unit 3 is provided with a first air outlet and a second air outlet, and the first air outlet is used for guiding the air flow to be led out along a first direction; the second air outlet is used for guiding the airflow to be led out in a second direction; the first direction and the second direction form an included angle, specifically, in this embodiment, the first direction is a horizontal direction, and the second direction is a vertical direction.

In order to adapt the double air guide plates to an air conditioner, the first air guide plate 11 and the second air guide plate 2 need to be perpendicular to each other, the first air guide plate 1 closes and opens the first air outlet, and the second air guide plate 2 closes and opens the second air outlet.

When the air conditioning mode is the horizontal air outlet mode, the driving component 4 drives the first transmission gear 43 to drive the first air deflector 1 to rotate, at this time, the first air deflector 1 and the second air deflector 2 are in the first state, that is, the first air deflector 1 rotates, but the second air deflector 2 does not rotate along with the rotation of the first air deflector 1, when the first transmission gear 43 rotates to the horizontal position, the boundary of the meshing gear section 432 of the first transmission gear 43 is connected with the output gear 42, that is, the first transmission gear 43 is meshed with the output gear 42, at this time, the first air deflector 1 and the second air deflector 2 form a plane, at this time, the first air deflector 1 can be used as an extension plate of the second air deflector 2, which is equivalent to increase the length of an air outlet channel, when the air conditioner blows, the air conditioner can be blown farther along the longer air outlet channel, so that the air conditioner can be effectively sent to all places of the space, the indoor environment temperature change is more obvious, and meanwhile, the air blown from the air outlet channel is not directly blown to the human body, and a better air supply effect can be achieved.

When the air conditioning mode is angular air outlet, at this time, the first transmission tooth 43 and the output tooth 42 are in the second state, the first transmission tooth 43 is meshed with the output tooth 42, when the first transmission tooth 43 rotates, the output tooth 42 can be driven to rotate, when the first transmission tooth 43 is driven to drive the first air deflector 1 to rotate, similarly, the output tooth 42 is also driven to rotate so as to drive the second air deflector 2 to rotate together, and the first air deflector 1 and the second air deflector 2 form a plane, when the plane is adjusted to a certain angle, the air conditioning air is blown out along the plane, and the first air deflector 1 is also used as an extension plate of the second air deflector 2, so that the air conditioning air can be sent further.

When the air conditioning mode is vertical air outlet, the first transmission teeth 43 and the output teeth 42 are still in the second state at the moment, namely the first transmission teeth 43 are meshed with the output teeth 42 and connected, the first air guide plate 1 and the second air guide plate 2 rotate simultaneously, the second air guide plate 2 seals the first air outlet at the moment, air conditioning air can be blown out from the second air outlet only, vertical air outlet is achieved, the air conditioning air is blown out along the vertical surface at the moment, and the indoor environment temperature can be adjusted more effectively due to the fact that the air supply distance is farther, and the temperature change is more obvious.

It should be noted that the first wind deflector 1 and the second wind deflector 2 are not necessarily perpendicular to each other, and the central angle of the tooth-lacking section 433 is not necessarily set to 90 °. The central angle of the tooth-lacking section 433 can be set to other degrees, so that an included angle can be formed between the first air deflector 1 and the second air deflector 2 in the second state, at the moment, the first air deflector 1 can play a role of a wind shield to prevent air conditioner wind from directly blowing to a human body, and a better air supply effect is achieved. The angle of the central angle of the tooth-missing section 433 can be set according to the actual requirement.

Of course, in other cases, the driven double air guide plates may also be applied to the fan, as long as air outlet in two directions needs to be realized, or the air outlet device in other prior art may also be applied to the bidirectional air guide plate, and the double air guide plates may be applied and set according to the needs of actual situations.

Further, as shown in fig. 2 and fig. 3, the first transmission tooth 43 includes a first transmission tooth 43 and a second transmission tooth 41, the first transmission tooth 43 includes a first transmission section and a second transmission section 431, the meshing tooth section 432 and the missing tooth section 433 are disposed in the first transmission section, and the second transmission section 431 is in meshing connection with the second transmission tooth 41.

On the basis of the above structure, the specific step of the process that the first transmission gear 43 drives the first air deflector 1 to rotate is that, when the driving motor 46 rotates, the first transmission gear 43 is driven to rotate through the transmission of the plurality of input gears, because the second transmission section 431 of the first transmission gear 43 is meshed with the second transmission gear 41, the first transmission section of the first transmission gear 43 is connected with the output gear 42, and the meshing gear section 432 and the missing gear section 433 are arranged on the first transmission section, then in the first state, the first transmission gear 43 rotates, the second transmission section 431 can drive the second transmission gear 41 to rotate, and further drive the first air deflector 1 to rotate, and the missing gear section 433 of the first transmission section rolls on the output gear 42, and cannot drive the output gear 42 to rotate, that is, the first air deflector 1 rotates, and the second air deflector 2 does not rotate along with the rotation of the first air deflector 1.

In the second state, the meshing section 432 of the first transmission section of the first transmission tooth 43 starts to be meshed with the output tooth 42, and then along with the rotation of the first transmission tooth 43, the second transmission section 431 can drive the second transmission tooth 41 to rotate, and meanwhile, the first transmission section can drive the output tooth 42 to rotate, that is, the first air deflector 1 and the second air deflector 2 rotate simultaneously.

Because the first transmission gear 43 is provided with the first transmission section and the second transmission section 431, the second transmission section 431 is meshed with the second transmission gear 41, the tooth-lacking section 433 on the first transmission section is in rolling connection with the output gear 42, and the tooth-meshing section 432 is meshed with the output gear 42, only one driving motor 46 is needed to drive the first transmission gear 43, so that the first air deflector 1 and the second air deflector 2 can be driven, and the first air deflector 1 and the second air deflector 2 are changed between the first state and the second state.

It should be noted that, in the present embodiment, the second transmission section 431 and the first transmission section are an integrally formed structure, and of course, the second transmission section 431 and the first transmission section may also be fastened and connected by a fastening member, for example, by a bolt connection, a welding or an adhesion manner, and may be selected and arranged according to the needs of actual situations.

Further, as shown in fig. 2, 5 and 6, a connection column is provided in the first air guiding plate 1, and a through hole 12 is provided on the connection column; the second air guiding plate 2 is provided with a first rotating shaft 21, and the first rotating shaft 21 is connected with the output tooth 42 synchronously after sequentially passing through the through hole 12 and the second transmission tooth 41.

On the basis of the above structure, when the first air deflector 1, the second air deflector 2 and the driving assembly 4 are assembled, the first rotating shaft 21 of the second air deflector 2 firstly passes through the through hole 12 of the first air deflector 1, then passes through the second transmission tooth 41, and then is connected with the output tooth 42. The first wind deflector 1 is connected to the second transmission gear 41.

Because the second air deflector 2 and the first air deflector 1 are in transmission connection with the gear on the same axis, in the second state, the first air deflector 1 and the second air deflector 2 can rotate from the same axis in the rotating process, so that the position between the first air deflector 1 and the second air deflector 2 cannot be changed relatively in the rotating process, and the rotation can be carried out more stably and stably. If the first air guiding plate 1 and the second air guiding plate 2 rotate in different axes, when the air conditioner is in the second state, the first air guiding plate 1 and the second air guiding plate 2 move up and down relatively in the rotating process, so that an assembly gap is formed, air leakage is possibly caused, energy loss is caused, and the working efficiency of the air conditioner is reduced.

Therefore, in the present embodiment, the through hole 12 is provided, and the first rotation shaft 21 is connected through the through hole 12. Of course, the selection and setting can be performed according to the requirements of actual situations.

On the basis of the structure, for realizing the synchronous connection of the first air deflector 1 and the second transmission gear 41, a first limiting part 411 is arranged on the second transmission gear 41, a second limiting part 11 is arranged on the connecting column, the second limiting part 11 is inserted and connected on the first limiting part 411 in a fixed mode, when the second transmission gear 41 rotates, due to the assembly of the first limiting part 411 and the second limiting part 11, the rotation of the second transmission gear 41 can drive the rotation of the first air deflector 1, and therefore the first air deflector 1 is driven.

Through with the spacing portion of second 11 cartridge on first spacing portion 411, can realize the assembly of first aviation baffle 1 with second driving gear 41, it is more laborsaving and convenient in the assembling process to can dismantle the connection and also make first aviation baffle 1 dismantle and wash or change.

It should be noted that, besides the above-mentioned inserting and fixing connection between the first limiting portion 411 and the second limiting portion 11, other methods may also be used to achieve the synchronous connection between the first wind deflector 1 and the second transmission gear 41, such as welding, bonding, etc., in which way the first wind deflector 1 cannot be detached and is difficult to clean and replace.

Or the first wind deflector 1 and the second transmission gear 41 can be synchronously connected by adopting the connection of fasteners such as bolts, and the disassembly is troublesome. Of course, other prior art can be adopted, and only the first air guiding plate 1 and the second transmission gear 41 need to be fixed, so that the second transmission gear 41 drives the first air guiding plate 1 to rotate, and the selection and the setting can be performed according to the needs of actual conditions.

Further, a limiting groove is formed in the first limiting portion 411, a limiting protrusion is formed on the connecting column to form a second limiting portion 11, and the limiting protrusion is inserted into the limiting groove, so that the first air deflector 1 is connected with the second transmission gear 41.

On the basis of the structure, a plurality of limiting grooves are distributed at intervals in the circumferential direction of the second transmission gear 41, a plurality of limiting protrusions are distributed at intervals in the circumferential direction of the connecting column correspondingly, and the limiting protrusions are inserted into the limiting grooves, so that the first air deflector 1 is connected with the second transmission gear 41.

By adopting the mode, the connection between the first air deflector 1 and the second transmission gear 41 is more stable, the situation that the first air deflector 1 is disconnected from the second transmission gear 41 in the rotating process can be effectively reduced, and the first air deflector 1 can be easily detached by the plug-in mounting mode, so that the cleaning and the replacement can be carried out, the service life of the driving mechanism is prolonged, and the use experience of a user is improved.

Alternatively, a limiting protrusion may be provided on the first limiting portion 411, a limiting groove may be provided on the second limiting portion 11, and the limiting protrusion may be inserted into the limiting groove, so that the same effect may be achieved.

On the basis of the above structure, when the second air deflector 2 is assembled with the output gear 42 and the first rotating shaft 21 passes through the second transmission gear 41, the gear shaft 421 of the output gear 42 is inserted into the shaft hole 22 of the first rotating shaft 21, thereby completing the assembly.

In this embodiment, specifically, the shaft hole 22 of the first rotating shaft 21 and the gear shaft 421 of the output gear 42 are both diamond-shaped, when the output gear 42 rotates, the gear shaft 421 on the output gear 42 also rotates, and since the gear shaft 421 is inserted into the shaft hole 22 of the first rotating shaft 21, the rotation of the gear shaft 421 will also drive the first rotating shaft 21 to rotate, so as to drive the second air guiding plate 2 to rotate.

Through the cooperation assembly of shaft hole 22 and axle, can make second aviation baffle 2 and first aviation baffle 1 coaxial rotation, and second aviation baffle 2 also can wash and change through dismantling, simple to operate is laborsaving.

Or, other methods in the prior art may also be adopted to achieve the assembly of the second air guiding plate 2 and the output tooth 42, for example, fastening members such as bolts are adopted for fastening, or welding and gluing are adopted for connecting, but in this way, the second air guiding plate 2 cannot be detached or is difficult to detach, and is difficult to clean and replace. Can be selected and set according to the requirements of actual conditions.

In addition, in this embodiment, the shaft holes 22 and the shafts are rhombic, so that when the shaft is rotated, the gear shaft 421 does not slide relatively in the shaft holes 22, but drives the shaft holes 22 to rotate synchronously, thereby enhancing the stability of the rotation process, and effectively reducing the occurrence of the situation that the gear shaft 421 is separated from the shaft holes 22 in the rotation process of the second air deflector 2. Of course, the shape of the shaft hole 22 and the shaft may also be set in other manners, such as a rectangle, a triangle, or an irregular shape, and the like, only the gear shaft 421 needs to be prevented from sliding in the shaft hole 22, and the shape can be selected and set according to the needs of actual situations.

Further, as shown in fig. 4, the meshing tooth section 432 includes a plurality of first protruding teeth provided on the first transmission section, the plurality of first protruding teeth being spaced apart in the circumferential direction of the first transmission tooth 43 and extending to the second transmission section 431 in the axial direction of the first transmission tooth 43; a plurality of second protruding teeth are arranged on the second transmission section 431, the plurality of second protruding teeth are correspondingly arranged on the position of the tooth-missing section 433 of the first transmission section, and the plurality of second protruding teeth and the plurality of first protruding teeth are distributed on the tooth sections of the second transmission section 431 to jointly form a meshing transmission structure of the second transmission section 431.

On the basis of above-mentioned structure, first transmission tooth 43 has included first transmission section and second transmission section 431, be equipped with meshing tooth section 432 and lack tooth section 433 on first transmission section, meshing tooth section 432 comprises a plurality of first protruding teeth, and first protruding tooth interval distribution on first transmission tooth 43's circumference, first protruding tooth extends to second transmission section 431 along the axial of first transmission tooth 43, protruding tooth on the first transmission section is integrated into one piece with the protruding tooth of the corresponding position on the second transmission section 431, and the position that corresponds on the second transmission section 431 and lack tooth section 433 is then equipped with the second protruding tooth, it is specific, in the axial that lacks tooth section 433 position, half is for lacking tooth section 433, half is the second protruding tooth.

When the double air guide plates are opened, the output teeth 42 and the first transmission teeth 43 are in the first state, the arc guide surfaces and the positioning teeth 422 slide relatively, and the arc guide surfaces are attached to tooth tops of the positioning teeth 422, so that the output teeth cannot rotate under the action of the weight of the second air guide plates or the force of external factors, and the second air guide plates cannot rotate along with the rotation of the first air guide plates in the first state.

When the double air guide plates are closed or the double air guide plates are changed from the second state to the first state, the output teeth 42 are changed from the state of meshing transmission with the meshing tooth sections 432 to the state of being disengaged from the tooth missing sections 433, when the positioning teeth 422 roll on the circular arc guide surfaces, the rotation is stopped after the positioning teeth 422 are abutted to the limiting teeth 434, and the double air guide plates are accurately closed.

When the double air deflectors are opened, the double air deflectors are in the first state at the moment, and if the positioning teeth 422 are not arranged or the tooth tops of the positioning teeth 422 cannot be attached to the circular arc guide surfaces, the output teeth 42 may rotate due to the self weight of the second air deflectors 2 or the action of external factors in the rotating process of the first transmission teeth 43. After the positioning teeth 422 are provided and the tooth tops of the positioning teeth 422 are attached to the arc guide surface, the resistance between the positioning teeth 422 and the arc guide surface blocks the output teeth 42 from rotating in the first state.

When the dual air guide plates are closed or the dual air guide plates are changed from the second state to the first state, at this time, the output teeth 42 and the first transmission teeth 43 still rotate, but the output teeth 42 rotate on the arc guide surface of the first transmission section and have rotation potential energy, and after the first transmission teeth 43 stop rotating, that is, after the first air guide plate 1 closes the first air outlet, if there is no limit tooth 434, the output teeth 42 continue to roll on the arc guide surface until the rotation potential energy is exhausted, so that the second air guide plate 2 cannot close the second air outlet tightly. Therefore, in order to ensure that the second air guiding plate 2 can also accurately close the second air outlet without over-rotation, the limiting tooth 434 is provided, when the output tooth 42 rotates to the position of the limiting tooth 434, the limiting tooth 434 is abutted against the output tooth 42 to prevent the output tooth 42 from continuously rotating, so that the second air guiding plate 2 is prevented from continuously rotating, and the second air outlet cannot be tightly closed.

In addition, the arc guide surface is adopted as the tooth lacking section 433, so that the positioning teeth 422 can be effectively ensured to roll smoothly on the arc guide surface, and the rotation of the output teeth 42 can not be driven when the tooth lacking section 433 rotates. Of course, other methods may be adopted as the toothless section 433, such as a slope, and if the slope does not abut against the output tooth 42, the toothless section 433 will not drive the output tooth 42 to rotate when rotating. Can be selected and set according to the requirements of actual conditions.

Further, the top of the limit tooth 434 is slightly lower than the first protruding tooth.

In addition to the above configuration, the first transmission tooth 43 rotates counterclockwise, the stopper tooth 434 can escape from the other teeth adjacent to the positioning tooth 422 and disengage from the output tooth 42, and the tip of the positioning tooth 422 starts to abut against the arc guide surface, thereby reducing the rotation of the output tooth 42.

When the double air guide plates are closed or the double air guide plates are changed from the second state to the first state, that is, when the first transmission teeth rotate anticlockwise, the limiting teeth 434 can keep away other teeth on the output teeth 42 adjacent to the positioning teeth 422, prevent the adjacent teeth from being continuously meshed with the limiting teeth 434 to cause the rotation of the output teeth 42, and enable the arc guide surfaces to be attached to the positioning teeth 422, so that the rotation of the output teeth 42 is stopped.

Further, as shown in fig. 3, the driving assembly 4 further includes a driving motor 46 and an input gear, the driving motor 46 is connected with the input gear in a transmission manner, and the input gear is connected with the first transmission gear 43 in a meshing manner. In this embodiment, specifically, the driving assembly 4 includes a first gear 44 and a second gear 45, the first gear 44 is in transmission connection with the motor, the second gear 45 is in meshing connection with the first gear 44 to perform the transmission function, and the second gear 45 is also in meshing connection with the first transmission gear 43, so as to drive the first transmission gear 43 to rotate.

On the basis of the above structure, after the driving motor 46 is started, the driving shaft drives the first gear 44 to rotate, the first gear 44 drives the second gear 45 to rotate, the second gear 45 drives the first transmission tooth 43 to rotate, and the first transmission tooth 43 drives the output tooth 42 and the second transmission tooth 41 to rotate.

Through the arrangement of the driving motor 46 and the input teeth, the transmission of the first transmission teeth 43 is realized, and further, the rotation of the first wind deflector 1 and the second wind deflector 2 is realized. Of course, drive assembly 4 also can adopt other modes to go on, in the utility model discloses in, do not restrict the quantity of the driving gear of input tooth, also can make driving motor 46 directly be connected with first driving gear 43 transmission, also can take more gears to carry out the transmission, perhaps use other drive methods among the prior art to carry out the transmission to first driving gear 43, select and set up according to actual conditions's needs.

Example 4, on the basis of all the structures described above,

an air conditioner as shown in fig. 7 is provided, the air conditioner includes an air conditioner main unit 3 and the above-mentioned driven double air guide plates, a refrigeration or heating module for an air conditioner in the prior art is arranged in the air conditioner main unit 3, and may be formed by a compressor, an evaporator, and the like, and a first air outlet and a second air outlet are arranged on the air conditioner main unit 3, the first air outlet is used for guiding an air flow out along a first direction; the second air outlet is used for guiding the air flow out along a second direction; the first direction and the second direction form an included angle, in the double air guide plates, the first air guide plate 1 is arranged at the first air outlet, and the first air guide plate 1 can seal or open the first air outlet; the second air deflector 2 is arranged at the second air outlet and can close or open the second air outlet.

Specifically, in this embodiment, in order to better implement cooling or heating, the first direction is a horizontal direction, the second direction is a vertical direction, and the first direction and the second direction are perpendicular to each other.

On the basis of the above structure, taking air conditioner refrigeration as an example, when the air conditioner is in a closed state, the first air deflector 1 and the second air deflector 2 are perpendicular to each other, at this time, the first air deflector 1 seals the first air outlet, and the second air deflector 2 seals the second air outlet.

After the air conditioner is started, a refrigerating or heating module in the air conditioner main unit 3 can refrigerate or heat, and generated hot air or cold air can be led out through a first air outlet or a second air outlet in the air conditioner main unit 3.

At this time, the driving motor 46 starts to work, when the first transmission gear 43 starts to rotate, the first air deflector 1 starts to rotate synchronously, and at this time, the tooth-missing section 433 of the first transmission gear 43 is in rolling connection with the output gear 42, so that the rotation of the first transmission gear 43 cannot drive the output gear 42 to rotate, and the second air deflector 2 cannot rotate along with the rotation of the first air deflector 1.

After the first transmission tooth 43 rotates to a certain angle, the first transmission tooth 43 rotates to the boundary between the tooth-missing section 433 and the tooth-meshing section 432 and starts to be meshed with the output tooth 42, and the tooth-meshing section 432 on the first transmission tooth 43 starts to be meshed with the output tooth 42, at this time, along with the rotation of the first transmission tooth 43, the output tooth 42 also rotates along with the first transmission tooth, that is, the first air deflector 1 and the second air deflector 2 start to rotate simultaneously, so that the air outlet modes at different angles are realized.

According to the far principle of air cold-hot circulation, the density of cold air is higher than that of air at normal temperature, the outlet air is blown upwards during refrigeration, and the cold air sinks to cool the whole room; the density of the hot air is lower than that of the air at normal temperature, the air is properly blown downwards during heating, and the hot air rises, so that the temperature of the whole room is raised.

Therefore, in this embodiment, the air-conditioning main unit 3 is provided with the first air outlet and the second air outlet, specifically, the first air outlet can horizontally output air, and the second air outlet can vertically output air, so that the double air guide plates can be adapted to the air conditioner, and the first air guide plate 1 and the second air guide plate 2 are required to be perpendicular to each other to close and open the first air outlet and the second air outlet.

Further, a third limiting portion is disposed at the second air outlet, and after the second air guiding plate 22 closes the second air outlet, the third limiting portion abuts against the second air guiding plate 2, so that the second air guiding plate 2 stops rotating.

On the basis of the structure, when the air conditioner is turned from the open state to the close state, the first air deflector 1 and the second air deflector 2 are in the second state in the open state, at the moment, the first air deflector 1 and the second air deflector 2 rotate simultaneously, and when the air conditioner is required to be turned off, the driving motor 46 drives the first transmission gear 43 to rotate in the opposite direction, so that the first air deflector 1 and the second air deflector 2 start to rotate in the opposite direction simultaneously.

When the first air deflector 1 and the second air deflector 2 rotate to the horizontal position, the second air outlet is already closed by the second air deflector 2 at this time, and because the third limiting part is arranged at the second air outlet, when the second air deflector 2 closes the second air outlet, the third limiting part is abutted against the second air deflector 2, so that the second air deflector 2 is prevented from continuing to rotate in the opposite direction.

Due to the arrangement of the third limiting portion, the second air guiding plate 2 is abutted against the third limiting portion in the rotating process, so that the second air guiding plate 2 can be effectively prevented from continuously rotating in the opposite direction, and the second air outlet can be tightly sealed by the second air guiding plate 2.

It should be noted that, in this embodiment, the third limiting portion is a limiting step disposed at the air outlet, and after the second air guiding plate 2 rotates to the air outlet, the limiting step abuts against the second air guiding plate 2, so as to apply resistance to the second air guiding plate 2 and prevent the second air guiding plate 2 from continuing to rotate.

Of course, the third limiting portion may be disposed by other methods, such as a protruding portion extending outward, or a blocking manner in the prior art, and only the resistance applied by the third limiting portion needs to prevent the second air guiding plate 2 from rotating continuously, and may be disposed according to the needs of actual situations.

Various other modifications and changes can be made by those skilled in the art based on the above-described technical solutions and concepts, and all such modifications and changes should fall within the scope of the claims.
