[0023] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. Now, in conjunction with the accompanying drawings, a detailed description of the preferred embodiments of the present utility model will be given.

[0024] The present invention provides a ventilated seat cushion. Figures 1 to 4As shown, the ventilated cushion includes a wind-repelling member 1 and a windproof back layer 2, a supporting layer 3, a wind-locking layer 4, and a contact surface layer 5 that are stacked in sequence to form a head portion 8, a middle portion 9, and a tail portion 10 that are sequentially connected on the ventilated cushion. The edges of the windproof back layer 2 and the contact surface layer 5 are sealed and connected. On the tail portion 10, an air inlet 6 and an air outlet 7 arranged on the contact surface layer 5 are provided on the ventilated cushion. The wind-repelling member 1 is installed in the air inlet 6, and the wind-repelling member 1 is used to drive external airflow into the interior of the ventilated cushion; wherein, the support layer 3 and / or the wind-locking layer 4 are not provided in the air inlet 6 area.

[0025] The ventilated seat cushion of the present invention does not include a support layer 3 and / or a wind-locking layer 4 in the area of the air inlet 6. That is, the ventilated seat cushion only has a windproof back layer 2 and a contact surface layer 5 as the back layer and surface layer in the area of the air inlet 6. This prevents the wind-locking layer 4 and the support layer 3 from blocking the incoming airflow at the air inlet 6, thereby increasing the air intake of the ventilated seat cushion. Furthermore, since the air inlet 6 is less obstructed, the driving resistance of the wind-repelling member 1 is reduced, the airflow flows more smoothly, and the noise of the wind-repelling member 1 is also reduced.

[0026] Specifically, the windproof back layer 2 serves as the back of the ventilated cushion. The windproof back layer 2 can prevent the airflow blown in by the wind-repellent part 1 from flowing away from the back of the ventilated cushion, allowing more airflow to be blown out from the front of the ventilated cushion through the air outlet 7, thereby achieving the effect of dissipating heat for the user. The windproof back layer 2 is made of pongee fabric. The supporting layer 3 supports and shapes the ventilated cushion as a whole, allowing the ventilated cushion as a whole to remain in a predetermined shape. The supporting layer 3 is air-permeable foam. The wind-locking layer 4 can be a 210D lining, which can lock the flowing airflow in the ventilated cushion lining to prevent leakage, allowing more airflow to flow out from the front of the ventilated cushion. The contact surface layer 5 serves as the front of the ventilated cushion and is in direct contact with the user. The contact surface layer 5 is a nine-hole mesh.

[0027] Specifically, the width of the wind-locking layer 4 is smaller than the width of the windproof back layer 2, the support layer 3, and the contact surface layer 5. The edge of the wind-locking layer 4 can be sewn together with the contact surface layer 5. When in use, the head portion 8 of the ventilated cushion corresponds to the head and neck of the user, and the middle portion 9 corresponds to the back and / or buttocks of the user. The edges of the windproof back layer 2 and the contact surface layer 5 can be sewn together to achieve a sealed connection, thereby forming an internal space with a certain degree of sealing within the ventilated cushion. The air inlet 6 and the air outlet 7 can be set at appropriate positions on the ventilated cushion, and the blown wind is blown out from the front of the ventilated cushion through the air outlet 7. In one embodiment, the air outlet 7 can be either set at an opening in the contact surface layer 5 or a gap in the contact surface layer 5 itself.

[0028] Specifically, the air-displacing element 1 is a turbofan. A turbofan uses a motor to drive the impeller, efficiently drawing air from the outside into the ventilated cushion. This drive mechanism, similar to a centrifugal fan, increases the momentum of the gas and converts kinetic energy into pressure energy through the scroll casing, effectively propulsing the airflow. Furthermore, the turbofan is quiet, helping to reduce noise during use of the ventilated cushion.

[0029] Specifically, the air inlet 6 is located on the rear portion 10, and the air outlet 7 is located on at least one of the head portion 8 and the middle portion 9. The rear portion 10 is not provided with a support layer 3 and / or a wind-locking layer 4. The placement of the air inlet 6 on the rear portion 10 and the air outlet 7 on the head portion 8 and / or the middle portion 9 facilitates uniform airflow distribution. Air enters the ventilated cushion from the rear portion 10, passes through the interior, and then exits through the air outlet 7 on the head portion 8 and / or the middle portion 9. This ensures effective ventilation for the user's back and buttocks, thereby improving overall comfort. Since the air inlet 6 region is not provided with a support layer 3 and / or a wind-locking layer 4, airflow can enter the ventilated cushion more smoothly, reducing airflow obstruction and thereby increasing air intake. This means that more outside air can be drawn into the ventilated cushion, accelerating internal air flow and improving heat dissipation efficiency. Since the air inlet 6 region lacks a wind-locking layer 4, the air-dispelling element 1 encounters less resistance when driving airflow, which helps reduce noise generation. In situations where prolonged sitting is required, such as in the office or on long drives, reducing noise can improve user comfort and concentration.

[0030] Furthermore, an air inlet 6 is provided on the contact surface layer 5 on the tail portion 10, and an air outlet 7 is provided on the contact surface layer 5 on at least one of the head portion 8 and the middle portion 9. By providing the air inlet 6 on the tail portion 10 and the air outlet 7 on both the head portion 8 and the middle portion 9, targeted ventilation can be provided to the user's back, buttocks, and head and neck. This design helps to dissipate heat more effectively because these areas are usually where more heat accumulates. The air flow enters from the tail portion 10, passes through the inside of the ventilated cushion, and is blown out from the air outlet 7 on the head portion 8 and the middle portion 9. This design can provide the user with a more comfortable sitting feeling. Especially in hot weather or when sitting and working for a long time, it helps to reduce the accumulation of sweat and heat.

[0031] Specifically, air outlets 7 are provided on the contact surface layer 5 at both the head portion 8 and the middle portion 9. By providing air outlets 7 in both the head portion 8 and the middle portion 9, the ventilated seat cushion provides uniform airflow across the user's entire sitting area, dissipating heat more comprehensively and enhancing user comfort. The presence of air outlets 7 in two zones allows airflow to be directed in two different directions, effectively reducing the temperature of the user's body in contact with the ventilated seat cushion, particularly in hot weather or when sitting for extended periods.

[0032] Furthermore, a first opening 11 is formed in the central portion 9, extending through the windproof back layer 2, the support layer 3, the wind-locking layer 4, and the contact surface layer 5. This first opening 11 further enhances the ventilation of the ventilated seat cushion. The windproof back layer 2, the support layer 3, the wind-locking layer 4, and the contact surface layer 5 are sewn together around the first opening 11 to ensure a certain degree of sealing within the ventilated seat cushion.

[0033] A first securing strap is provided on the back or both sides of the central portion 9. This securing strap prevents the ventilated cushion from sliding or shifting during use, thereby improving its stability. The first securing strap can include an elastic strap and a buckle. The elastic strap is sewn onto the back or both sides of the central portion 9, with the ends connected to buckles that snap together during use to secure the ventilated cushion. Conventional elastic straps and buckles can be used, and their details are omitted here.

[0034] Furthermore, second securing straps are provided on either side, back, or top of the head portion 8. These straps further secure the ventilated cushion, preventing it from sliding or shifting during use and improving its stability. The second securing straps can include elastic bands and buckles. These elastic bands are sewn to the back or both sides of the middle portion 9, with buckles attached at the ends. These buckles snap together to secure the cushion during use. Conventional elastic bands and buckles can be used, and their details are omitted here.

[0035] It should be understood that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Those skilled in the art may modify the technical solutions described in the above embodiments, or make equivalent replacements for some of the technical features therein; and all these modifications and replacements should fall within the scope of protection of the claims attached to the present invention.
