It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0023] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0024] Please refer to Figure 1 and Figure 2 A car seat air-blowing and suction circulation ventilation system is applied to a car seat, which includes a seat cushion and a backrest. A car seat air circulation ventilation system includes: The air bag structure includes a seat cushion air bag 1 and a backrest air bag 2. The seat cushion air bag 1 and the backrest air bag 2 are respectively arranged on the seat cushion and backrest of the car seat. Several air distribution holes are provided on the side wall of the seat cushion air bag 1 and the backrest air bag 2 near the passenger. The ventilation circulation structure is installed on the car seat, with its two ends connected to the seat cushion air bag 1 and the backrest air bag 2 respectively, so that the airflow is delivered from the backrest air bag 2 to the seat cushion air bag 1, or from the seat cushion air bag 1 to the backrest air bag 2. By setting up a ventilation circulation structure, airflow can circulate between the seat cushion air bag 1 and the backrest air bag 2. Specifically, when the seat cushion air bag 1 needs to perform the blowing function, outside air is drawn in, passes through the backrest, and is drawn in through the air distribution hole of the backrest air bag 2. After passing through the ventilation circulation structure, it blows towards the passenger through the air distribution hole of the seat cushion air bag 1 and the seat cushion. When the backrest air bag 2 needs to perform the blowing function, outside air is drawn in, passes through the seat cushion, and is drawn in through the air distribution hole of the seat cushion air bag 1. After passing through the ventilation circulation structure, it blows towards the passenger through the air distribution hole of the backrest air bag 2 and the backrest. This achieves the situation of air intake at one end and air blowing at the other end, which can meet the usage needs of different passengers. Both the seat cushion air bag 1 and the backrest air bag 2 have several air distribution holes on the side wall near the passenger to allow airflow.

[0025] The ventilation circulation structure includes a suction component, which includes two fans 3. The two fans 3 are respectively set for the seat cushion air bag 1 and the backrest air bag 2, and are used to ventilate the seat cushion air bag 1 and the backrest air bag 2, thereby achieving ventilation towards the side of the seat cushion closer to the passenger and towards the side of the backrest closer to the passenger.

[0026] Specifically, the two fans 3 are respectively located on the side of the seat cushion and backrest away from the passenger.

[0027] The fan 3 has an air intake end and an air outlet end. The air intake ends of the two fans 3 are respectively connected to the seat cushion air bag 1 and the backrest air bag 2.

[0028] Optionally, fan 3 is a suction fan; Therefore, by activating the fan 3 corresponding to the seat cushion air bag 1, external air passes through the seat cushion and enters the seat cushion air bag 1 through the air distribution hole of the seat cushion air bag 1, and then blows towards the passenger through the air distribution hole of the backrest air bag 2. By activating the fan 3 corresponding to the backrest air bag 2, external air passes through the backrest and enters the backrest air bag 2 through the air distribution hole of the backrest air bag 2, and then blows towards the passenger through the air distribution hole of the seat cushion air bag 1.

[0029] The ventilation circulation structure also includes a connecting pipe, which includes a seat cushion connecting pipe 4 and a backrest connecting pipe 5. One end of the seat cushion connecting pipe 4 is connected to the air outlet of the fan 3 of the corresponding seat cushion air bag 1, and one end of the backrest connecting pipe 5 is connected to the air outlet of the fan 3 of the corresponding backrest air bag 2. Furthermore, the connecting pipe also includes a telescopic pipe 6, with its two ends connected to the end of the seat cushion connecting pipe 4 away from the seat cushion air bag 1 and the end of the backrest connecting pipe 5 away from the backrest air bag 2, respectively. Therefore, by connecting the pipes, airflow can be circulated between the seat cushion air bag 1 and the backrest air bag 2, such as... Figure 3 As shown, when the seat cushion air bag 1 needs to perform the blowing function, the fan 3 set on the backrest is activated, and the outside air enters the backrest air bag 2 and is delivered into the connecting pipe. The airflow passes through the backrest connecting pipe 5, the telescopic pipe 6 and the seat cushion connecting pipe 4 in sequence, enters the seat cushion air bag 1 through the fan 3 of the corresponding seat cushion air bag 1, and is blown towards the passenger through several air distribution holes of the seat cushion air bag 1. During this process, the fan 3 of the corresponding seat cushion air bag 1 does not work. like Figure 4 As shown, when the backrest air bag 2 needs to perform the blowing function, the fan 3 set in the seat cushion is activated, and the outside air enters the seat cushion air bag 1 and is delivered into the connecting pipe. The airflow passes through the connecting pipe in sequence, and then passes through the telescopic tube 6 and the backrest connecting tube 5 in sequence. After passing through the fan 3 of the corresponding backrest air bag 2, it enters the backrest air bag 2 and is blown towards the passenger through several air distribution holes of the backrest air bag 2. During this process, the fan 3 of the corresponding backrest air bag 2 does not work. It should be noted that when the backrest is rotated to adjust the angle of the car seat, the telescopic tube 6 can provide sufficient deformation to avoid damage to the connecting pipe; the type of telescopic tube 6 can be a corrugated pipe.

[0030] The seat cushion includes seat cushion foam 8, and the backrest includes backrest foam 7; In this embodiment, the seat cushion air bag 1 is located on the side of the seat cushion foam 8 away from the passenger, and the seat cushion foam 8 is provided with a number of ventilation holes 9 corresponding to a number of air distribution holes; the backrest air bag 2 is located on the side of the backrest foam 7 away from the passenger, and the backrest foam 7 is provided with a number of ventilation holes 9 corresponding to a number of air distribution holes. Therefore, by setting ventilation holes 9 on the seat cushion foam 8 and the backrest foam 7, when the seat cushion air bag 1 needs to perform the blowing function, the airflow is blown to the passenger through the ventilation holes 9 of the seat cushion foam 8 via several air distribution holes of the seat cushion air bag 1. When the backrest air bag 2 needs to perform the blowing function, the airflow is blown to the passenger through the ventilation holes 9 of the backrest foam 7 via several air distribution holes of the backrest air bag 2.

[0031] In other embodiments, the seat cushion air bag 1 is disposed on the side of the seat cushion foam 8 close to the passenger, and a through hole is provided on the seat cushion foam 8 for connecting the seat cushion air bag 1 and the air intake end of the fan 3 of the corresponding seat cushion air bag 1; optionally, a pipe can be provided in the through hole to realize the flow of air, or no pipe can be provided, and the airflow can be realized only through the through hole. The backrest air bag 2 is located on the side of the backrest foam 7 closest to the passenger. A through hole is provided on the backrest foam 7 to connect the backrest air bag 2 and the air intake hole of the fan 3 of the corresponding backrest air bag 2. Optionally, a pipe can be provided in the through hole to realize the airflow, or no pipe can be provided, and the airflow can be realized only through the through hole.

[0032] Therefore, when the seat cushion air bag 1 needs to perform the air blowing function, the airflow is blown towards the passenger through several air distribution holes of the seat cushion air bag 1, and when the backrest air bag 2 needs to perform the air blowing function, the airflow is blown towards the passenger through several air distribution holes of the backrest air bag 2.

[0033] Working principle: When the seat cushion air bag 1 needs to perform the blowing function, the fan 3 set on the backrest is activated, and the outside air enters the backrest air bag 2. At this time, the backrest achieves the suction effect, and the outside air is delivered into the connecting pipe. The airflow passes through the backrest connecting pipe 5, the telescopic pipe 6 and the seat cushion connecting pipe 4 in sequence, enters the seat cushion air bag 1 through the fan 3 of the corresponding seat cushion air bag 1, and is blown towards the passenger through several air distribution holes of the seat cushion air bag 1. During this process, the fan 3 of the corresponding seat cushion air bag 1 does not work. When the backrest air bag 2 needs to perform the blowing function, the fan 3 set in the seat cushion is activated, and the outside air enters the seat cushion air bag 1. At this time, the seat cushion air bag 1 achieves the suction effect, and the outside air is delivered into the connecting pipe. The airflow passes through and is delivered into the connecting pipe in sequence. The airflow passes through the telescopic tube 6 and the backrest connecting tube 5 in sequence, and enters the backrest air bag 2 through the fan 3 of the corresponding backrest air bag 2. It is then blown towards the passenger through several air distribution holes of the backrest air bag 2. During this process, the fan 3 of the corresponding backrest air bag 2 does not work. Depending on the actual needs of different passengers, the fan 3 installed on the backrest or the fan 3 installed on the seat cushion can be activated to achieve the effect of air intake at the backrest and air blowing at the seat cushion, or air blowing at the backrest and air intake at the seat cushion, so as to realize the interchange of blowing and suction to meet the needs of passengers.
