[0024] In this embodiment, the driving assembly 6 includes a horizontal plate 61, which is fixed to the inner wall of the fixed box 1. The upper surface of the horizontal plate 61 is fixedly connected to the vertical plate 62. One side of the vertical plate 62 is fixedly connected to the driving motor 63. The main shaft of the driving motor 63 is fixedly connected. The first round rod 64 is fixedly connected to one of the fans 3. The first round rod 64 passes through the shell 2 and is rotatably connected to the shell 2. A toggle assembly 7 is provided on the first round rod 64. The toggle assembly 7 is used to drive the other fan 3 to rotate. The driving motor 63 is started, and one of the fans 3 is driven to rotate through the first round rod 64 to generate airflow to cool the room. At the same time, the first round rod 64 drives the second fan 3 to rotate through the driving assembly 6, so that the two fans 3 rotate, accelerate the indoor air circulation, and promote indoor cooling.

[0025] In this embodiment, the toggle assembly 7 includes a second round rod 71, which is fixedly connected to another fan 3. The second round rod 71 passes through the shell 2 and is rotatably connected to the shell 2. One end of the second round rod 71 is provided with a first gear 72. The outer side of the first round rod 64 is fixedly connected to the second gear 73, and the second gear 73 is meshed with the first gear 72. The first round rod 64 is driven by a driving motor 63. The first round rod 64 drives the second round rod 71 to rotate through the first gear 72 and the second gear 73. The rotation directions of the fans 3 driven by the first round rod 64 and the second round rod 71 are opposite. At this time, suction is generated in one shell 2 and blowing is generated in the other shell 2, forming an indoor and outdoor airflow flow cycle on both sides of the room, thereby accelerating the indoor ventilation speed.

[0026] In this embodiment, one end of the second round rod 71 is fixedly connected to the mounting shell 8, and the mounting shell 8 is fixedly connected to the electric push rod 9. The telescopic rod of the electric push rod 9 is fixedly connected to the first gear 72. The first gear 72 is fixedly connected to two support rods 10 on the side close to the mounting shell 8. The two support rods 10 both penetrate the side wall of one side of the mounting shell 8. The support rod 10 is slidably connected to the mounting shell 8. The first gear 72 is installed on the telescopic rod of the electric push rod 9. When there are too many people in the room and it is necessary to increase the ventilation strength of the room, the driving motor 63 drives the second gear 73 to rotate slowly, and the electric push rod 9 pushes the first gear 7 2 is close to the second gear 73. When the first gear 72 is close to the teeth on the second gear 73 and is aligned, the first gear 72 moves to be flush with the second gear 73, and the teeth on the first gear 72 and the second gear 73 are meshed. At this time, the driving motor 63 can directly drive the two fans 3 to form air circulation in the room, which has the strongest ventilation effect in the room. When there are fewer people in the room, the driving motor 63 stops, and the electric push rod 9 pulls the first gear 72 away from the second gear 73. At this time, the driving motor 63 drives one fan 3 to rotate, and the indoor ventilation requirements can be met by a single fan 3, which is more flexible to use.

[0027] In this embodiment, the outer tube 5 is L-shaped, located above the shell 2 , and tilted downward. The outer tube 5 is connected to the outside, and the tilted setting can prevent rainwater from entering the shell 2 through the outer tube 5 .

[0028] In this embodiment, the inner tube 4 is Z-shaped, the two inner tubes 4 extend in different directions, the openings of the two inner tubes 4 are both downward, and the inner tubes 4 extend laterally in different directions. When the driving motor 63 can directly drive the two fans 3 to form an air circulation in the room, the wind directions in the two inner tubes 4 are different, and the distance is too far so that they will not interfere with each other, so that the wind can blow all around the room.

[0029] In this embodiment, a filter box 11 is installed at one end of the outer tube 5 connected to the outside world and one end of the inner tube 4 connected to the indoor room. The filter box 11 is used to filter dust. The filter box 11 is set at one end of the outer tube 5 and the outside world to prevent dust, lint and the like from entering the shell 2 and entangled with the fan 3, causing the rotation of the fan 3 to be obstructed.

[0030] Working principle: when there are too many people in the room and it is necessary to increase the ventilation intensity of the room, the driving motor 63 drives the second gear 73 to rotate slowly, and the electric push rod 9 pushes the first gear 72 close to the second gear 73. When the first gear 72 is close to the second gear 73 and the teeth are aligned, the first gear 72 moves to be flush with the second gear 73, and the teeth on the first gear 72 and the second gear 73 are meshed. At this time, the driving motor 63 can directly drive the two fans 3 to form an air circulation in the room, which has the strongest ventilation effect in the room. When there are fewer people in the room, the driving motor 63 stops, and the electric push rod 9 pulls the first gear 72 away from the second gear 73. At this time, the driving motor 63 drives one fan 3 to rotate, and the indoor ventilation requirements can be met by a single fan 3. During ventilation, the filter box 11 filters dust.

[0031] Of course, the present utility model may have many other implementations. Based on the present implementation, other implementations obtained by ordinary technicians in this field without any creative work are all within the scope of protection of the present utility model.
