     TECHNICAL FIELD 
     The invention relates to the technical field of air outflow, and particularly provides an air outflow device, a console and a vehicle. 
     BACKGROUND ART 
     Vehicles are one of indispensable transportation means for people to go out. In order to improve comfort, an air outflow device is generally provided in a vehicle. In hot summer, the air outflow device can deliver cold air into the vehicle to reduce the temperature in the vehicle. In cold winter, the air outflow device can deliver warm air into the vehicle to increase the temperature in the vehicle. The configuration of the air outflow device enables a driver and a passenger to drive and ride the vehicle under appropriate temperature conditions regardless of freezing winter and sultry summer, greatly improving the comfort. Generally, in order to adjust an air outflow direction of the air outflow device, louvers are provided at an air outlet of the air outflow device, and when it is necessary to adjust the air outflow direction, the driver or the passenger needs to manually turn the louvers to adjust the air outflow direction, bringing inconvenience in use to the driver or the passenger. 
     Therefore, there is a need in the art for a novel air outflow device, a console and a vehicle to solve the above problem. 
     SUMMARY OF THE INVENTION 
     The invention provides an air outflow device, in order to solve the above problem in the prior art whereby louvers in an air outflow device in a current vehicle needs to be manually turned to adjust an air outflow direction, bringing inconvenience in use. The air outflow device comprises a shell, wherein an air channel is formed in the shell, the air channel comprises an air inflow section and a first air outflow section and a second air outflow section separately in communication with the air inflow section, an opening/closing member and an air distribution member are rotatably disposed in the air inflow section, and an outlet of the first air outflow section and an outlet of the second air outflow section are respectively provided with a first louver structure and a second louver structure. When air flows out of both the outlet of the first air outflow section and the outlet of the second air outflow section, an airflow flowing out of the outlet of the first air outflow section is capable of at least partially merging with an airflow flowing out of the outlet of the second air outflow section. A first driving member and a second driving member are disposed outside the air channel. The first driving member is capable of driving the opening/closing member to open/close the air inflow section so as to connect/disconnect the air inflow section, and is capable of driving the air distribution member to rotate so as to adjust an opening degree of an inlet of the first air outflow section or an inlet of the second air outflow section, adjusting an air outflow amount and a longitudinal air outflow direction. The second driving member is capable of driving the first louver structure and the second louver structure to swing together so as to adjust a transverse air outflow direction. 
     With such a configuration, it is possible to change the longitudinal and transverse air outflow directions of the air outflow device by means of the first driving member and the second driving member without the need for manually turning the louvers to adjust the air outflow direction, such that the air outflow device is convenient to use. In addition, the first driving member can not only adjust the longitudinal air outflow direction by driving the air distribution member, but also can drive the opening/closing member to control the opening/closing of the air inflow section, that is to say, the air distribution member and the opening/closing member are both controlled by means of one first driving member, thereby achieving two functions of adjusting the longitudinal air outflow direction and controlling the opening/closing of the air inflow section. In comparison with driving the air distribution member and the opening/closing member respectively by means of different driving members, such an air outflow device has a more compact structure, which is beneficial to a miniaturization design of the air outflow device. Moreover, the first louver structure and the second louver structure can be both driven by means of one second driving member, such that the air outflow device has a more compact structure, which is more beneficial to the miniaturized design of the air outflow device. 
     In a preferred technical solution of the air outflow device described above, the first driving member is a first electric motor, the air distribution member is fixedly connected to an output portion of the first electric motor, a first sliding structure and a stop member are further fixedly connected to the output portion of the first electric motor, a transmission member fixedly connected to the opening/closing member is disposed outside the air channel, and a second sliding structure is disposed on the transmission member; when the first sliding structure is not slidably connected to the second sliding structure, the stop member is capable of preventing the movement of the transmission member; and when the first sliding structure is slidably connected to the second sliding structure, the stop member is capable of disengaging from the transmission member to allow the movement of the transmission member under the action of the first sliding structure. 
     With such a configuration, the transmission member is prevented from rotating due to its own weight or an external force when there is no need to rotate. Therefore, the situation is prevented that the first sliding structure and the second sliding structure cannot smoothly enter a slidable connection state due to the rotation of the transmission member, and the opening/closing member rotates is prevented from rotating due to the rotation of the transmission member, otherwise the air inflow section is mistakenly connected or disconnected.

     With such a configuration, it is possible to allow the stop member to restrict the movement of the transmission member in a timely manner by means of a relatively simple structure. In addition, such a structure is easy to machine, which is beneficial to improving the production efficiency. 
     In a preferred technical solution of the air outflow device described above, the second driving member is a second electric motor, a connecting column is fixedly connected to an output portion of the second electric motor, a first protrusion and a second protrusion are formed on the connecting column, a column sleeve is fitted over the connecting column, a first helical groove and a second helical groove respectively corresponding to the first protrusion and the second protrusion are formed on the column sleeve, the first helical groove and the second helical groove have the same helical direction, and a first transmission rod and a second transmission rod are further fixed to the column sleeve; the first transmission rod is connected to the first louver structure by means of a first transmission assembly, and the second transmission rod is connected to the second louver structure by means of a second transmission assembly; a third sliding structure is disposed on the column sleeve, a fourth sliding structure slidably connected to the third sliding structure is further disposed in the shell, and the third sliding structure and the fourth sliding structure are relatively slidable only in an axial direction of the column sleeve; the second electric motor is capable of driving the column sleeve to rotate such that the first protrusion and the second protrusion respectively slide in the first helical groove and the second helical groove, the column sleeve moves in the axial direction, the first transmission rod and the second transmission rod then both move in the axial direction, and the first transmission assembly and the second transmission assembly are moved to drive the first louver structure and the second louver structure to swing together in the same direction.

For those skilled in the art, the specific meaning of the above-mentioned terms in the invention can be interpreted according to the specific situation. 
     As shown in  FIGS. 1 to 7 , the invention provides an air outflow device (two air outflow devices are shown in  FIG. 1 ). The air outflow device comprises a shell  1 . An air channel is formed in the shell  1 , the air channel comprises an air inflow section  11  and a first air outflow section  12  and a second air outflow section  13  respectively in communication with the air inflow section  11 . An opening/closing member  2  and an air distribution member  3  are rotatably disposed in the air inflow section  11 , and an outlet of the first air outflow section  12  and an outlet of the second air outflow section  13  are respectively provided with a first louver structure  1201  and a second louver structure  1301 . When air flows out of both the outlet of the first air outflow section  12  and the outlet of the second air outflow section  13 , an airflow flowing out of the outlet of the first air outflow section  12  can at least partially merge with an airflow flowing out of the outlet of the second air outflow section  13 . A first driving member  4  and a second driving member  5  are disposed outside the air channel. The first driving member  4  can drive the opening/closing member  2  to open/close the air inflow section  11  so as to connect/disconnect the air inflow section  11  and can drive the air distribution member  3  to rotate so as to adjust an opening degree of an inlet of the first air outflow section  12  or an inlet of the second air outflow section  13 , adjusting an air outflow amount and a longitudinal air outflow direction. The second driving member  5  can drive the first louver structure  1201  and the second louver structure  1301  to swing together so as to adjust a transverse air outflow direction. 
     It should be noted that the air outflow device of the invention may be applied to a vehicle, or be applied to a household air conditioner or other equipment in which an airflow needs to be delivered. Such an adjustment of application objects of the air outflow device does not limit the invention, which shall be limited within the scope of protection of the invention. The air inflow section  11  is in communication with an air source (for example, a fan and an air conditioning system of an vehicle). When the opening/closing member  2  opens the air inflow section  11 , the airflow from the air source can flow through the air inflow section  11 , the air outflow device can deliver the airflow from the air source out of the outlet of the first air outflow section  12  and the outlet of the second air outflow section  13 . When the opening/closing member  2  closes the air inflow section  11 , since the air inflow section  11  is disconnected, the airflow from the air source cannot flow through the air inflow section  11 , and the outlet of the first air outflow section  12  and the outlet of the second air outflow section  13  in the air outflow device stop delivering the airflow. 
     The air distribution member  3  rotates to adjust the opening degree of the inlet of the first air outflow section  12  or the inlet of the second air outflow section  13 . That is to say, the air distribution member  3  can alternatively block the inlet of the first air outflow section  12  or the inlet of the second air outflow section  13 . When the inlet of the first air outflow section  12  is blocked, the inlet of the first air outflow section  12  can be completely or partially blocked. When the inlet of the second air outflow section  13  is blocked, the inlet of the second air outflow section  13  can be completely or partially blocked. In the case where the first air outflow section  12  is located above the second air outflow section  13  (it is the case shown in  FIG. 1 ), when the air distribution member  3  completely blocks the inlet of the first air outflow section  12 , all the air is distributed to the second air outflow section  13 , at this moment, the blown air will be blown downwards at the maximum limit angle, and the longitudinal air outflow direction is the air outflow direction of the second air outflow section  13  in a longitudinal direction. When the air distribution member  3  completely blocks the inlet of the second air outflow section  13 , all the air is distributed to the first air outflow section  12 , at this moment, the blown air will be blown upwards at the maximum limit angle, and the longitudinal air outflow direction is the air outflow direction of the first air outflow section  12  in the longitudinal direction. When the air distribution member  3  partially blocks the inlet of the first air outflow section  12 , most of the air is distributed to the second air outflow section  13 , and a small part of the air is distributed to the first air outflow section  12 , at this moment, the air blown out by the second air outflow section  13  is partially offset by the air blown out by the first air outflow section  12 , thereby making the longitudinal air outflow direction slightly downward compared with the air outflow direction when the air distribution member  3  completely blocks the inlet of the first air outflow section  12 . When the air distribution member  3  partially blocks the inlet of the second air outflow section  13 , most of the air is distributed to the first air outflow section  12 , and a small part of the air is distributed to the second air outflow section  13 , at this moment, the air blown by the first air outflow section  12  is partially offset by the air blown by the second air outflow section  13 , thereby making the longitudinal air outflow direction slightly upward compared with the air outflow direction when the air distribution member  3  completely blocks the inlet of the second air outflow section  13 . 
     In the above description, the opening/closing member  2  may use an opening/closing plate, an opening/closing block, etc., and those skilled in the art would have been able to flexibly the specific structure of the opening/closing member  2  in practical applications as long as the opening/closing member  2  can open/close the air inflow section  11  under the drive of the first driving member  4  so as to connect/disconnect the air inflow section  11 . The air distribution member  3  may be a sector-shaped air distribution block, a circular air distribution block, etc., and those skilled in the art would have been able to flexibly the specific structure of the air distribution member  3  in practical applications as long as the air distribution member  3  can rotate under the drive of the first driving member  4  to adjust the opening degree of the inlet of the first air outflow section  12  or the inlet of the second air outflow section  13 , adjusting the air outflow amount and the longitudinal air outflow direction. 
     Preferably, as shown in  FIGS. 3 and 4 , the first driving member  4  is a first electric motor, the air distribution member  3  is fixedly connected to an output portion of the first electric motor, a first sliding structure  401  and a stop member  402  are further fixedly connected to the output portion of the first electric motor, a transmission member  6  fixedly connected to the opening/closing member  2  is disposed outside the air channel, and a second sliding structure  601  is disposed on the transmission member  6 . When the first sliding structure  401  is not slidably connected to the second sliding structure  601 , the stop member  402  can prevent the movement of the transmission member  6 . When the first sliding structure  401  is slidably connected to the second sliding structure  601 , the stop member  402  can disengage from the transmission member  6  to allow the movement of the transmission member  6  under the action of the first sliding structure  401 . In the case shown in  FIGS. 3 and 4 , the first sliding structure  401  is a slider, and the second sliding structure  601  is a sliding groove. During rotation of the output portion of the first electric motor in the counterclockwise direction, the slider is gradually slidably connected to the sliding groove. When the slider starts to be slidably connected to the sliding groove, the stop member  402  exactly disengages from the transmission member  6 . During relative sliding between the slider and the sliding groove, the transmission member  6  rotates under the action of the slider. When the slider slides to the tail end of the sliding groove (at this moment, the slider cannot continue to slide along the sliding groove), the opening/closing member  2  rotates to a position where the air inflow section  11  can be closed, so as to disconnect the air inflow section  11 , such that the airflow from the air source cannot flow through the air inflow section  11 . Later, the output portion of the first electric motor can rotate in the clockwise direction, at this moment, the slider slides out of the sliding groove. During the sliding, the transmission member  6  rotates under the action of the slider such that the opening/closing member  2  rotates to a position where the air inflow section  11  can be opened, so as to connect the air inflow section  11 , and at the moment when the slider is separated from the sliding groove, the stop member  402  comes into contact with the transmission member  6  again and prevents the movement of the transmission member  6 . 
     Instead of the electric motor, the first driving member  4  may also be a combined structure of a gear, a rack and an air cylinder. Specifically, the air cylinder is directly connected to the rack, the rack meshes with the gear, and a shaft passes through a central hole of the gear to serve as an output shaft. Those skilled in the art would have been able to flexibly the specific structure of the first driving member  4  in practical applications, and such an adjustment and change in the specific structure of the first driving member  4  do not limit the invention, which shall be limited within the scope of protection of the invention. The first sliding structure  401  may be a sliding groove, a slider, etc., the second sliding structure  601  may accordingly be a slider, a sliding groove, etc., and the transmission member  6  may be a transmission plate, a transmission rod, etc. Those skilled in the art would have been able to flexibly the specific structures of the first sliding structure  401 , the second sliding structure  601  and the transmission member  6  in practical applications, and such adjustments and changes in the specific structures of the first sliding structure  401 , the second sliding structure  601  and the transmission member  6  do not limit the invention, which shall be limited within the scope of protection of the invention. 
     Alternatively, instead of fixedly connecting the stop member  402  to the output portion of the first electric motor, it is also possible that the transmission member  6  is configured to be made of a magnetically attractable material such as iron and nickel or a magnet is fixed to the transmission member  6 , and an electromagnet is disposed in the shell  1 . When it is necessary to prevent the movement of the transmission member  6 , the electromagnet is energized to prevent the movement of the transmission member  6  by means of magnetic attraction. 
     Preferably, as shown in  FIGS. 3 and 4 , the stop member  402  is a stop block having an arc-shaped groove  500 , and an arc-shaped edge  600  slidably cooperating with the arc-shaped groove  500  is formed on the transmission member  6 . In addition, it is also possible that an arc-shaped groove is formed on the transmission member  6 , the stop member  402  is a stop block having an arc-shaped block, and the arc-shaped block has the same curvature as the arc-shaped groove. When the arc-shaped block slides in the arc-shaped groove, the stop member  402  can also prevent the movement of the transmission member  6 . When the arc-shaped block completely slides out of the arc-shaped groove, that is to say, when the stop member  402  disengages from the transmission member  6 , the transmission member  6  can move at this moment. Those skilled in the art would have been able to flexibly the specific structure of the stop member  402  in practical applications, as long as the stop member  402  can prevent the movement of the transmission member  6  when the first sliding structure  401  is not slidably connected to the second sliding structure  601 , and when the first sliding structure  401  is slidably connected to the second sliding structure  601 , the stop member  402  can disengage from the transmission member  6  to allow the movement of the transmission member  6  under the action of the first sliding structure  401 . 
     Preferably, as shown in  FIGS. 5 and 7 , the second driving member  5  is a second electric motor, a connecting column  501  is fixedly connected to an output portion of the second electric motor, a first protrusion  5011  and a second protrusion  5012  are formed on the connecting column  501 , a column sleeve  502  is fitted over the connecting column  501 , a first helical groove  100  and a second helical groove  200  respectively corresponding to the first protrusion  5011  and the second protrusion  5012  are formed on the column sleeve  502 , and the first helical groove  100  and the second helical groove  200  have the same helical direction.

It should be noted that the fourth sliding structure  811  disposed in the shell  1  may be connected to the shell  1  or may be connected to other components, for example, a mounting base  81  of the first electric motor, and a mounting base  82  of the second electric motor.

The first snap-fit portion  50211  and the second snap-fit portion  50221  may be a snap hook and a snap slot, a snap slot and a snap button, etc. Those skilled in the art would have been able to flexibly the specific structures of the first snap-fit portion  50211  and the second snap-fit portion  50221  in practical applications, as long as the first snap-fit portion  50211  and the second snap-fit portion  50221  can be snap-fitted each other. 
     Alternatively, the column sleeve  502  may be configured to comprise a first half column sleeve  5021  and a second half column sleeve  5022  which are slidably connected to each other, the first helical groove  100  is formed in the first half column sleeve  5021 , the second helical groove  200  is formed in the second half column sleeve  5022 , and the first helical groove  100  and the second helical groove  200  have opposite helical directions. In this way, the first louver structure  1201  and the second louver structure  1301  can swing together in opposite directions, that is to say, the first louver structure  1201  and the second louver structure  1301  swing together in opposite directions. With such a configuration, air can flow out of the first louver structure  1201  and the second louver structure  1301  in different transverse directions at the same time, so that the use requirements for multi-directional air outflow can be met. 
     Preferably, as shown in  FIGS. 5 and 6 , the first louver structure  1201  comprises a plurality of first louvers, and the first transmission assembly comprises a first mounting plate  71  and at least one first connecting rod  72 .

     Alternatively, the first transmission assembly may be configured to comprise a gear and a rack that mesh with each other. The rack is fixedly connected to the first transmission rod  50201 , a connecting shaft is disposed on the first louvers, and the connecting shaft passes through a central hole of the gear and is fixedly connected to the gear. When the first transmission rod  50201  moves, the rack also moves therewith and drives the gear to rotate, thereby rotating the first louvers. Similarly, the second transmission assembly may use a gear and rack structure, which will not be described in detail.

     In a possible case, as shown in  FIG. 7 , a first auxiliary mounting groove  300  and a second auxiliary mounting groove  400  are formed in the end of the column sleeve  502  close to the output portion of the second electric motor, the first auxiliary mounting groove  300  is in communication with the end of the first helical groove  100  close to the output portion of the second electric motor, and the second auxiliary mounting groove  400  is in communication with the end of the second helical groove  200  close to the output portion of the second electric motor. With such a configuration, when the column sleeve  502  and the connecting column  501  are assembled, the first protrusion  5011  and the second protrusion  5012  can respectively enter the first helical groove  100  and the second helical groove  200  through the first auxiliary mounting groove  300  and the second auxiliary mounting groove  400 , facilitating assembly of the column sleeve  502  and the connecting column  501 . 
     In another possible case, a third auxiliary mounting groove and a fourth auxiliary mounting groove are formed in the end of the column sleeve  502  remote from the output portion of the second electric motor, the third auxiliary mounting groove is in communication with the end of the first helical groove  100  remote from the output portion of the second electric motor, and the fourth auxiliary mounting groove is in communication with the end of the second helical groove  200  remote from the output portion of the second electric motor. With such a configuration, when the column sleeve  502  and the connecting column  501  are assembled, the first protrusion  5011  and the second protrusion  5012  can respectively enter the first helical groove  100  and the second helical groove  200  through the third auxiliary mounting groove and the fourth auxiliary mounting groove, facilitating assembly of the column sleeve  502  and the connecting column  501 . 
     In still another possible case, a first auxiliary mounting groove  300  and a second auxiliary mounting groove  400  are formed in the end of the column sleeve  502  close to the output portion of the second electric motor, the first auxiliary mounting groove  300  is in communication with the end of the first helical groove  100  close to the output portion of the second electric motor, and the second auxiliary mounting groove  400  is in communication with the end of the second helical groove  200  close to the output portion of the second electric motor; and a third auxiliary mounting groove and a fourth auxiliary mounting groove are formed in the end of the column sleeve  502  remote from the output portion of the second electric motor, the third auxiliary mounting groove is in communication with the end of the first helical groove  100  remote from the output portion of the second electric motor, and the fourth auxiliary mounting groove is in communication with the end of the second helical groove  200  remote from the output portion of the second electric motor. With such a configuration, when the column sleeve  502  and the connecting column  501  are assembled, the first protrusion  5011  and the second protrusion  5012  can respectively either enter the first helical groove  100  and the second helical groove  200  through the first auxiliary mounting groove  300  and the second auxiliary mounting groove  400 , or enter the first helical groove  100  and the second helical groove  200  through the third auxiliary mounting groove and the fourth auxiliary mounting groove, providing two ways of assembly, and further facilitating assembly of the column sleeve  502  and the connecting column  501 . 
     Preferably, as shown in  FIG. 4 , a rotation stop structure  5013  is disposed on the connecting column  501 , a limiting structure is disposed on a mounting base  82  of the second electric motor, and the limiting structure can restrict a rotation stroke of the rotation stop structure  5013  to restrict a rotation stroke of the connecting column  501 , thereby restricting swing ranges of the first louver structure  1201  and the second louver structure  1301 . In the case shown in  FIG. 4 , the rotation stop structure  5013  is a rotation stop plate, and the limiting structure is two limiting blocks, and the rotation stop plate can only move between the two limiting blocks, namely, the rotation stroke of the rotation stop plate is restricted. Of course, the rotation stop structure  5013  may also be configured as a slider, and the limiting structure may be configured as a limiting groove in which the slider slides. When sliding to two ends of the limiting groove, the slider is limited, thereby restricting the rotation stroke of the slider. Those skilled in the art would have been able to flexibly the specific structures of the rotation stop structure  5013  and the limiting structure in practical applications, as long as the limiting structure can restrict the rotation stroke of the rotation stop structure  5013  to restrict the rotation stroke of the connecting column  501 , thereby restricting the swing ranges of the first louver structure  1201  and the second louver structure  1301 . 
     Preferably, a flow guiding structure is disposed between the outlet of the first air outflow section  12  and the outlet of the second air outflow section  13 . The flow guiding structure comprises a first flow guiding portion and a second flow guiding portion. A first end of the first flow guiding portion is connected to the outlet of the first air outflow section  12 , and the first flow guiding portion is configured to be capable of guiding a flow in a tangential direction of the outlet of the first air outflow section  12 . A first end of the second flow guiding portion is connected to the outlet of the second air outflow section  13 , and the second flow guiding portion is configured to be capable of guiding a flow in a tangential direction of the outlet of the second air outflow section  13 . A second end of the first flow guiding portion is connected to a second end of the second flow guiding portion. 
     The “tangential direction” of the invention will be explained below by taking the first air outflow section  12  and the first flow guiding portion as an example, which specifically means that the first flow guiding portion is connected to an edge of the outlet of the first air outflow section  12 , and an extension direction of the first flow guiding portion is substantially parallel to the air outflow direction of the first air outflow section  12 , thereby ensuring that the air coming out of the first air outflow section  12  can be delivered by a longer distance under the action of the first flow guiding portion, and that the air straightly flows. 
     Further, the shape of the outlet of the first air outflow section  12  may be a rectangle as illustrated in  FIG. 1 , or may be a circle, etc. Accordingly, the shape of the first flow guiding portion also needs to be adjusted adaptively according to the shape of the outlet of the first air outflow section  12 . Those skilled in the art would have been able to flexibly set the shape of the outlet of the first air outflow section  12  and the shape of the first flow guiding portion, as long as long-distance straight delivery of the air discharged from the first air outflow section  12  can be achieved under the action of the first flow guiding portion, and this adjustment of the shape does not limit the invention. Similarly, those skilled in the art would have been able to flexibly set the shape of the outlet of the second air outflow section  13  and the shape of the second flow guiding portion, which will not be described in detail herein. 
     In a preferred case, the shape of the outlet of the first air outflow section  12  is the same as that of the outlet of the second air outflow section  13  (for example, the outlet of the first air outflow section  12  and the outlet of the second air outflow section  13  shown in  FIG. 1  are both rectangles with the same sizes), thereby providing a more favorable structural foundation for fluid design for the distribution of the air amount and the adjustment of the air outflow direction. Of course, in practical applications, the shape of the outlet of the first air outflow section  12  and the shape of the outlet of the second air outflow section  13  may also be different, which is not limited by the invention. 
     Preferably, the outlet of the first air outflow section  12  and the outlet of the second air outflow section  13  are each provided with a grid, which can at least play a decorative role. 
     Furthermore, the invention further provides a console. The console is disposed between a driver seat and a co-driver seat, and comprises a housing and the air outflow device as described above. The air outflow device is disposed in the housing, a covering portion is formed to extend on the housing, and the covering portion is capable of at least partially shielding the outlet of the first air outflow section  12  and the outlet of the second air outflow section  13 . 
     Preferably, two air outflow devices are disposed in the housing, the outlets of the first air outflow sections  12  of the two air outflow devices are both located at the upper portion, the outlets of the second air outflow sections  13  of the two air outflow devices are both located at the lower portion, and the outlets of the first air outflow sections  12  of the two air outflow devices may share a grid or may separately use a grid. Similarly, the outlets of the second air outflow sections  13  of the two air outflow devices may share a grid or may separately use a grid. When the first louver structures  1201  and the second louver structures  1301  of the air outflow devices swing in the same direction, by disposing two air outflow devices, air can be delivered in different transverse air outflow directions at the same time. For example, one of the air outflow devices delivers air to the left and the other of the air outflow devices delivers air to the right. 
     Finally, the invention further provides a vehicle, comprising the air outflow device as described above or the console as described above. It should be noted that if the vehicle comprises an air outflow device, the air outflow device may be disposed between any two adjacent seats, or may be disposed at an instrument panel, etc.

Those skilled in the art could make equivalent changes or substitutions to the related technical features without departing from the principles of the invention, and all the technical solutions after the changes or the substitutions will fall within the scope of protection of the invention.
