[0002] The ventilation function of air conditioning is to quickly discharge the dirty air in the room to achieve the purpose of purifying the air; the existing ventilation function is used to extract the dirty air in the room to the outside (the outdoor air can be brought into the room from ventilation positions such as windows) or to introduce outdoor air into the room (thereby squeezing the dirty air in the room from ventilation positions such as windows to the outside). The two methods can be adaptively selected according to the distribution and concentration of the dirty air in the room; the two existing ventilation methods are switched by the forward and reverse rotation of the motor. When the outdoor air is drawn into the room, a filter is often set in the outdoor air intake pipe to filter the dust in the outdoor air; when the motor switches the rotation direction to extract the indoor air to the outside, the position of the filter does not change, which will cause the next time the outdoor air is drawn into the room, the particles on the filter will follow the air into the room again.

[0007] As a further solution of the present invention, the driving mechanism includes a motor, and the motor is fixedly mounted on the bottom of the connecting head by bolts; the output shaft of the motor is fixedly connected to the rotating shaft of the pump casing.

[0008] As a further solution of the present invention, the bottom of the filter plate is rotatably connected to a first baffle, and a torsion spring for resetting the first baffle is sleeved on the rotation axis of the first baffle.

[0018] When working, Figure 1 and Figure 2 As shown, when the exhaust fan 5 is Figure 2When working in the state shown, the exhaust fan 5 draws outdoor air into the room, so as to squeeze the dirty air in the room out of the window and other places. After the air enters the air inlet pipe 2, it will be filtered by the filter plate 7, and then enter the room through the connecting head 1, the pump housing 4 and the air outlet pipe 3; when it is necessary to directly draw the dirty air in the room to the outside, the driving mechanism drives the pump housing 4 to rotate 180° in the connecting head 1, and the pump housing 4 will drive the exhaust fan 5 to rotate 180° synchronously; the exhaust fan 5 changes the exhaust direction, and at this time the exhaust fan 5 can work to draw the dirty air in the room to the outside; it should be noted that the driving mechanism drives the pump housing 4 to rotate 180° in the connecting head 1. In the process of rotating the pump housing 4 by 180°, the pump housing 4 will drive the second bevel gear 16 to rotate synchronously, the second bevel gear 16 will drive the first bevel gear 14 to rotate synchronously, the first bevel gear 14 will drive the cylindrical cam 13 to rotate synchronously through the first rotating shaft 12, the cylindrical cam 13 will drive the guide rod 11 to move away from the installation frame 6 through the cam groove 15, the guide rod 11 will drive the first slider 9 to move synchronously, the first slider 9 will drive the filter plate 7 to move upward through the pull rope 10, so that the filter plate 7 moves to the top of the intake pipe 2, and the air will not pass through the exhaust fan 5 when it works to draw the indoor air to the outside. The filter plate 7 can greatly reduce the working pressure of the filter plate 7, increase the service life of the filter plate 7, and the filter screen 7 will not block the discharge of particulate matter in the dirty air, so as to better purify the indoor air; the present invention designs the connecting head 1 and the pump housing 4 into a spherical shape, the pump housing 4 can rotate smoothly in the connecting head 1, the pump housing 4 can drive the exhaust fan 5 to rotate and change the exhaust direction at any time (even when the exhaust fan is working), and can ensure the sealing between the connecting head 1 and the air inlet pipe 2 and the air outlet pipe 3, and when the pump housing 4 is not working, the driving mechanism can drive the pump housing 4 to drive the exhaust fan 5 to rotate 90°, so that the opening of the pump casing 4 is staggered with the opening of the connecting head 1, the exhaust fan 5 will not be exposed to the air when not working, which can avoid a large amount of dust adhering to the surface of the exhaust fan, and enable the exhaust fan 5 to work better when needed; through the arrangement of the cylindrical cam 13 and the guide rod 11, the cylindrical cam 13 can drive the guide rod 11 to move accurately to the specified position regardless of forward or reverse rotation, so when the driving mechanism drives the pump casing 4 to rotate, it can be clockwise, counterclockwise, or switched between clockwise and counterclockwise, so the selection of the motor 17 is relatively simple.

[0019] As a further solution of the present invention, the driving mechanism includes a motor 17 , and the motor 17 is fixedly mounted on the bottom of the connecting head 1 by bolts; the output shaft of the motor 17 is fixedly connected to the rotating shaft of the pump housing 4 .

[0020] When working, Figure 2 As shown, the motor 17 can drive the pump housing 4 to rotate in the connecting head 1.

[0021] As a further solution of the present invention, the bottom of the filter plate 7 is rotatably connected to a first baffle 18, and a torsion spring for resetting the first baffle 18 is sleeved on the rotation axis.

[0022] When working, Figure 2-Figure 4 As shown, a first baffle 18 rotatably mounted therewith is provided at the bottom of the filter plate 7. When the exhaust fan 5 draws outdoor air into the room through the air inlet pipe 2, a large amount of dust will slowly accumulate at the outer end of the filter plate 7. As the dust accumulates, dust will fall off and the fallen dust will accumulate on the first baffle 18 instead of accumulating at the bottom of the mounting frame 6, thereby preventing dust from accumulating at the bottom of the mounting frame 6 and affecting the sealing of the filter plate 7. When the exhaust fan 5 needs to switch the working state (when the outdoor air needs to be discharged to the outside through the air outlet pipe 3), the filter plate 7 will drive the first baffle 18 to move upward. When the indoor air flows through the air inlet pipe 2, the air pressure in the air inlet pipe 2 will decrease, and the first baffle 18 will shake under the action of the air pressure. The dust on the first baffle 18 will fall off when it shakes and be discharged along with the indoor air, thereby ensuring that the dust on the filter plate 7 can be discharged in time and will not accumulate on the first baffle 18.

[0023] As a further solution of the present invention, the top of the filter plate 7 is rotatably connected to a second baffle 19, an incomplete gear 20 is fixedly connected to the rotating shaft of the second baffle 19, and a rack rod 21 capable of meshing with the incomplete gear 20 is fixedly connected to the inner wall of the mounting frame 6; an air inlet 22 is opened on the top of the mounting frame 6, and a sealing block 23 is slidably connected to the top of the mounting frame 6, and the sealing block 23 is used to seal the air inlet 22.

[0024] When working, Figure 2-Figure 4 As shown, when the filter plate 7 moves upward, it will drive the second baffle 19 to move upward synchronously, and the second baffle 19 will drive the incomplete gear 20 to move upward synchronously. When the incomplete gear 20 moves to mesh with the rack rod 21, the rack rod 21 will drive the incomplete gear 20 to rotate upward, and the incomplete gear 20 will drive the second baffle 19 to rotate until it is vertical. When the second baffle 19 moves to the highest point, it will drive the sealing block 23 to move upward to open the air inlet 22; then when the exhaust fan 5 works to discharge the indoor air to the outside, when the air flows through the intake pipe 2, The air pressure in the intake pipe 2 is reduced, and then the outside air can enter the mounting frame 6 from the air inlet 22 under the action of air pressure, and then enter the intake pipe 2 from the mounting frame 6 and be discharged. The air flow can promote the dust adhering to the surface of the filter plate 7 to fall off, and at the same time make the dust on the first baffle 18 fall off and be discharged faster; in the initial state, the second baffle 19 is in a horizontal state. At this time, the second baffle 19 can play a sealing role, which can prevent a large amount of dust from entering the upper part of the mounting frame 6 and accumulating on the top of the second baffle 19, affecting the operation of the second baffle 19.

[0025] As a further solution of the present invention, a pressure spring 24 is fixedly connected to the top of the filter plate 7 , and the top end of the pressure spring 24 is fixedly connected to the mounting frame 6 .

[0026] When working, Figure 2 As shown, by setting the pressure spring 24, the pressure spring 24 can make the filter plate 7 Figure 2 In the state, it fits more closely with the installation frame 6, so that the sealing effect is better.

[0027] As a further solution of the present invention, a reinforcing rib 25 is provided between the fixing plate 8 and the mounting frame 6 .

[0028] When working, Figure 1 As shown, by providing the reinforcing ribs 25, the fixing plate 8 can work more stably.

[0029] Working principle: Figure 1 and Figure 2 As shown, when the exhaust fan 5 is Figure 2When working in the state shown, the exhaust fan 5 draws outdoor air into the room, so as to squeeze the dirty air in the room out of the window and other places. After the air enters the air inlet pipe 2, it will be filtered by the filter plate 7, and then enter the room through the connecting head 1, the pump housing 4 and the air outlet pipe 3; when it is necessary to directly draw the dirty air in the room to the outside, the driving mechanism drives the pump housing 4 to rotate 180° in the connecting head 1, and the pump housing 4 will drive the exhaust fan 5 to rotate 180° synchronously; the exhaust fan 5 changes the exhaust direction, and at this time the exhaust fan 5 can work to draw the dirty air in the room to the outside; it should be noted that the driving mechanism drives the pump housing 4 to rotate 180° in the connecting head 1. In the process of rotating the pump housing 4 by 180°, the pump housing 4 will drive the second bevel gear 16 to rotate synchronously, the second bevel gear 16 will drive the first bevel gear 14 to rotate synchronously, the first bevel gear 14 will drive the cylindrical cam 13 to rotate synchronously through the first rotating shaft 12, the cylindrical cam 13 will drive the guide rod 11 to move away from the installation frame 6 through the cam groove 15, the guide rod 11 will drive the first slider 9 to move synchronously, the first slider 9 will drive the filter plate 7 to move upward through the pull rope 10, so that the filter plate 7 moves to the top of the intake pipe 2, and the air will not pass through the exhaust fan 5 when it works to draw the indoor air to the outside. The filter plate 7 can greatly reduce the working pressure of the filter plate 7, increase the service life of the filter plate 7, and the filter screen 7 will not block the discharge of particulate matter in the dirty air, so as to better purify the indoor air; the present invention designs the connecting head 1 and the pump housing 4 into a spherical shape, the pump housing 4 can rotate smoothly in the connecting head 1, the pump housing 4 can drive the exhaust fan 5 to rotate and change the exhaust direction at any time (even when the exhaust fan is working), and can ensure the sealing between the connecting head 1 and the air inlet pipe 2 and the air outlet pipe 3, and when the pump housing 4 is not working, the driving mechanism can drive the pump housing 4 to drive the exhaust fan 5 to rotate 90°, so that the opening of the pump casing 4 is staggered with the opening of the connecting head 1, the exhaust fan 5 will not be exposed to the air when not working, which can avoid a large amount of dust adhering to the surface of the exhaust fan, and enable the exhaust fan 5 to work better when needed; through the arrangement of the cylindrical cam 13 and the guide rod 11, the cylindrical cam 13 can drive the guide rod 11 to move accurately to the specified position regardless of forward or reverse rotation, so when the driving mechanism drives the pump casing 4 to rotate, it can be clockwise, counterclockwise, or switched between clockwise and counterclockwise, so the selection of the motor 17 is relatively simple.
