Further, the first fan assembly 2 includes a first motor 22 and a first impeller 10, the first motor 22 has a first output shaft 11, and the first impeller 10 and the first output shaft 11 are coaxially fixedly connected; The first output shaft 11 is driven by the first motor 22 to rotate, thereby driving the first impeller 10 to rotate; Furthermore, the first installation space is circumferentially provided with a first opening 8 connected thereto, a first ventilation space is formed inside the first impeller 10, a plurality of first air inlets and outlets 12 connected to the first ventilation space are evenly provided circumferentially on the first impeller 10, and a second air inlet and outlet 13 connected to the first ventilation space is provided on one side of the first impeller 10 close to the first output shaft 11, and the second air inlet and outlet 13 is connected to the first installation space; Furthermore, the second fan assembly 3 includes a second motor 23 and a second impeller 14, the second motor 23 has a second output shaft 15, and the second impeller 14 and the second output shaft 15 are coaxially fixedly connected;

It should be noted that if Figure 1 and Figure 2As shown, at this time, the first air inlet and outlet 12 and the third air inlet and outlet 16 are arranged close to each other in the first direction, that is, the first impeller 10 and the second impeller 14 are in a normal installation form; When the first fan assembly 2 is in the first state, the first motor 22 drives the first impeller 10 to rotate, and the second fan assembly 3 is in the second state, and the second motor 23 does not work; When the second fan assembly 3 is in the first state, the second motor 23 drives the second impeller 14 to rotate, and at this time, the first fan assembly 2 is in the second state, and the first motor 22 does not work;

[0027] A control circuit board 4, which is disposed between the first fan assembly 2 and the second fan assembly 3. Optionally, the control circuit board 4 can be disposed in the first installation space or in the second installation space; Furthermore, the control circuit board 4 has a first surface side and a second surface side that are far away from each other, the first surface side corresponds to the first fan assembly 2 and is electrically connected to the first fan assembly 2, the second surface side corresponds to the second fan assembly 3 and is electrically connected to the second fan assembly 3, and the control circuit board 4 is used to control the first fan assembly 2 or the second fan assembly 3 respectively, so that when the first fan assembly 2 is in the first state, the second fan assembly is in the second state, or when the first fan assembly 2 is in the first state, the second fan assembly 3 is in the second state.

[0028] Alternatively, if Figures 1 to 4As shown, the connecting housing 7 may be an integrated structure, which includes a third connecting plate 21; Further, when the connection housing 7 is an integrated structure, the control circuit board 4 is arranged on the third connection plate 21, and the first surface side and the second surface side are used to control the first fan assembly 2 and the second fan assembly 3 respectively; Further, optionally, as Figure 1 and Figure 2 As shown, the first air inlet and outlet 12 and the third air inlet and outlet 16 are arranged close to each other in the first direction. In order to realize airflow circulation, the second air inlet and outlet 13 is opened on the side of the first impeller 10 close to the first output shaft 11, and the fourth air inlet and outlet 17 is opened on the side of the second impeller 14 close to the second output shaft 15; Thus, when the first fan assembly 2 is in the first state, the external wind flow is sucked in through the second opening 9, and then passes through the third air inlet and outlet 16, the fourth air inlet and outlet 17, the through hole 18, the second air inlet and outlet 13 and the first air inlet and outlet 12 in sequence, and is blown out from the first opening 8; Figure 1 The direction of the middle arrow is the wind flow direction; When the second fan assembly 4 is in the first state, the external wind flow is sucked in through the first opening 8, and then passes through the first air inlet and outlet 12, the second air inlet and outlet 13, the through hole 18, the fourth air inlet and outlet 17 and the third air inlet and outlet 16 in sequence, and is blown out from the second opening 9; Figure 2 The direction of the middle arrow is the wind flow direction; Alternatively, if Figure 7 As shown, the first air inlet and outlet 12 and the third air inlet and outlet 16 are arranged away from each other in the first direction. At this time, the first impeller 10 and the second impeller 14 are compared. Figure 1 In the reverse installation form, the second air inlet and outlet 13 and the fourth air inlet and outlet 17 do not need to be provided; Therefore, when the first fan assembly 2 or the second fan assembly 3 is in the first state, the wind flows through the first air inlet and outlet 12 or the second air inlet and outlet 13 and then directly passes through the through hole 18 to achieve ventilation.

[0029] It should be noted that if Figure 7 The reversed first impeller 10 and second impeller 14 shown can also be arranged on the hollow cup motor. The reversed first impeller 10 and second impeller 14 can make the air flow path more unobstructed, so that the blowing effect and the suction effect of the first fan assembly 2 and the second fan assembly 3 are better.

[0030] It should be noted that the first impeller 10 and the second impeller 14 are different. The first impeller 10 and the second impeller 14 may be different in size or shape, that is, the first impeller 10 and the second impeller 14 may be different in at least one of the length, thickness, and inclination angle of the blades.

[0031] Working principle: The device is installed on the car seat, and the first fan assembly 2 and the second fan assembly 3 are controlled separately by the control circuit board 4. When the first fan assembly 2 is in the first state, the second fan assembly is in the second state, and when the first fan assembly 2 is in the first state, the second fan assembly 3 is in the second state, that is, when the first fan assembly 2 is working, it blows air and sucks air through the second fan assembly 3, and when the second fan assembly 3 is working, it blows air and sucks air through the first fan assembly 2, thereby realizing the selection of blowing and sucking modes for the car seat, realizing effective air circulation on the seat surface under the required environment, and avoiding discomfort to the human body in a single mode.
