Description

Technical Field

[0001] This utility model belongs to the field of daily necessities technology, and in particular relates to a ventilated seat cushion. Background Technology

[0002] Seat cushions, as a key functional component of the interface between the human body and the seat, are widely used in car seats, office chairs and other scenarios. Their core function is to relieve pressure distribution and improve comfort.

[0003] Traditional seat cushions often use materials such as polyurethane foam and memory foam, which can improve body pressure distribution. However, due to the limitations of the material's thermal conductivity and breathability, they cannot prevent continuous heat accumulation. During prolonged use, they can form a local microenvironmental thermal barrier, causing the temperature and humidity in the area in contact with the buttocks to rise continuously. This can lead to discomfort such as stuffiness, stickiness, and sweat accumulation in the user's buttocks, and may even induce skin diseases. Summary of the Invention

[0004] The purpose of this utility model is to overcome the defects of the prior art by providing a ventilated seat cushion, which solves the problem that the seat cushion cannot block the continuous heat accumulation, and that after long-term use, the user's buttocks will be covered with heat and moisture, resulting in stuffiness and discomfort.

[0005] The technical solution of this utility model is as follows: A ventilated seat cushion includes a cushion body and a fan fixedly installed in the cushion body. The cushion body has a cavity, and the side wall of the cavity is provided with an opening. The air outlet of the fan is aligned with the opening of the cavity, and the air inlet of the fan is open to the outside. The top of the cushion body is provided with an air duct groove, and the top of the cavity is provided with an air guide port connecting the air duct groove and the cavity.

[0006] A further feature of this invention is that cavities are provided on both the left and right sides of the pad, and the two cavities are indirectly connected through an air duct.

[0007] A further feature of this invention is that the pad includes a base plate and an anti-slip plate disposed below the base plate, the cavity is formed by a groove opened at the bottom of the base plate and the anti-slip plate, and the air duct is disposed at the top of the base plate.

[0008] A further feature of this invention is that the anti-slip plate and the substrate are connected by a support structure. The support structure includes a positioning post protruding from the anti-slip plate and a snap-fit ​​post protruding downward from the top surface of the groove on the substrate. The positioning post is provided with a snap-fit ​​groove for the snap-fit ​​post to be inserted and tightly fitted.

[0009] A further feature of this invention is that each fan has a cavity with an opening on the side wall.

[0010] A further feature of this invention is that the top of the pad is provided with a honeycomb-shaped array of hexagonal protrusions, and the gaps between adjacent protrusions of the air duct groove are connected.

[0011] A further feature of this invention is that the pad body also includes a circuit board and a power supply, the circuit board being electrically connected to the fan, and the power supply being electrically connected to the circuit board.

[0012] The beneficial effects of this invention are as follows: When a user sits on the cushion and comes into contact with the protrusions, the air duct is located under the user's buttocks. Active ventilation can remove the heat accumulated in the buttocks. In addition, the double cavities of the entire cushion are set in parallel, with a large coverage area, so that the edge area also has airflow. The air duct between the honeycomb protrusions can achieve full-area ventilation and uniform airflow distribution, which can increase the diffusion rate of moisture, thereby avoiding the situation of stuffiness, stickiness and sweat accumulation in the buttocks.

[0019] like Figure 1-5 As shown, a ventilated seat cushion includes a cushion body 1. A fan 3, a circuit board 7, and a power supply 8 are fixedly installed inside the cushion body 1. The circuit board 7 is electrically connected to the fan 3 and has a switch on it for controlling the fan to turn on or off. The switch is exposed to the top end face of the cushion body 1. The power supply 8 is electrically connected to the circuit board 7 and provides energy to the circuit board 7 and the fan 3.

[0020] The cushion 1 contains a cavity 2. In this embodiment, two cavities 2 are provided, which correspond to the position of the user's buttocks when sitting down, and the two cavities 2 are relatively isolated in the cushion 1. The pad 1 includes a base plate 11 and an anti-slip plate 12 disposed below the base plate 11. Each cavity 2 is composed of a groove opened at the bottom of the base plate 11 and an anti-slip plate 12. The bottom end face of the anti-slip plate 12 may also be provided with anti-slip texture to prevent it from sliding when placed on the seat. Several sets of support structures are provided in the corresponding cavities 2 between the anti-slip plate 7 and the base plate 11. Each support structure includes a positioning post 13 protruding on the anti-slip plate 12 and a snap-fit ​​post 14 protruding downward from the top surface of the groove of the base plate 11. The positioning post 13 is provided with a snap-fit ​​groove 15 for the snap-fit ​​post 14 to be inserted and tightly fitted. The support structures are evenly distributed in the cavities 2 to support the user and the base plate 11 and prevent the air duct from collapsing after sitting for a long time.

[0021] The cavity 2 has an opening on its side wall. The air outlet of the fan 3 is aligned with the opening of the cavity 2. The air inlet of the fan 3 is open to the outside. In this embodiment, four fans 3 are used, each pair corresponding to one cavity 2. Each cavity 2 has two openings on its side wall, and each opening corresponds to one fan 3. The top of the base 11 is provided with a mesh ventilation port 4 to allow the air inlet of the fan 3 to be open to the outside. Each fan 3 corresponds to one mesh ventilation port 4. The top of the substrate 11 is provided with a honeycomb-shaped array of hexagonal protrusions 5. The gaps between adjacent protrusions 5 form an air duct groove 6. The air duct groove 6 includes a straight groove extending along one side of the hexagonal protrusions 5 and a triangular groove at the intersection of three hexagonal protrusions 5.

[0022] The top of the cavity 2 is provided with a ventilation channel 6 and an air inlet 9 connecting the cavity 2, and the two cavities 2 are indirectly connected through the ventilation channel 6.

[0023] Specifically, when a user sits on the cushion 1, their buttocks are positioned above the two cavities 2 and in contact with the protrusions 5. At this point, pressing the switch exposed at the top of the cushion 1 turns on each fan 3. Each fan 3 draws in air through the mesh ventilation opening 4, pressurizes it, and delivers it to the corresponding cavity 2. The air then enters the air duct 6 through the air guide 9. The air duct 6 is located below the user's buttocks, and active ventilation can remove the heat accumulated in the buttocks. The parallel arrangement of the two cavities of the entire cushion provides a large coverage area, ensuring airflow even at the edges. The air duct 6 with its honeycomb protrusions allows for full-area ventilation and uniform airflow distribution, increasing the rate of moisture diffusion and preventing the buttocks from feeling stuffy, sticky, or accumulating sweat.
