[0027] With the popularity of cars, cars have become an indispensable means of transport in life, and when sitting in a car for a long time, the hips and back often sweat due to the poor ventilation of the car seat, which even affects the health. The current market has a certain ventilation and heat dissipation effect, and the fan is installed below the cushion and blows towards the ventilation hole of the cushion, but the car seat needs to be provided with an air inlet at another position for the fan, resulting in a complex structure of the car seat.

[0028] The utility model provides a cushion ventilation structure, aims at solving how to simplify the structure of the cushion or bed applied by the cushion ventilation structure.

[0029] In the utility model embodiment, as shown in Figures 1 to 3 The cushion ventilation structure comprises a cushion 10, an air inlet area 11 and an air outlet area 12 of the cushion 10, an air inlet hole 13 is formed in the air inlet area 11, an air outlet hole 14 is formed in the air outlet area 12, the air inlet hole 13 and the air outlet hole 14 penetrate the first surface and the second surface of the cushion 10, a gas driving device 20 is arranged below the cushion 10, the air inlet end of the gas driving device 20 is communicated with the air inlet hole 13, the air outlet end of the gas driving device 20 is communicated with the air outlet hole 14, and the air inlet airflow and the air outlet airflow generated when the gas driving device 20 operates all pass through the cushion 10.

[0030] In the embodiment, the cushion 10 can be a seat cushion, a back cushion or a bed cushion, the first surface of the cushion 10 is used for users to sit, lean or lie, and the cushion 10 can be made of elastic material to improve the experience of users to sit, lean or lie. When the cushion 10 is used as a seat cushion or a back cushion, the hips or back of the user can be ventilated and cooled. When the cushion 10 is used as a bed cushion, the whole body of the user lying on the bed cushion can be ventilated and cooled.

[0031] The air inlet hole 13 and the air outlet hole 14 both penetrate the cushion 10 along the thickness direction of the cushion 10. Taking the seat cushion as an example, the gas driving device 20 is used to drive the gas to flow from the air inlet end to the air outlet end, so that the gas on one side of the first surface of the cushion 10 can flow to the second surface side of the cushion 10 through the air inlet hole 13, and then flow back to the first surface side of the cushion 10 through the air outlet hole 14. The air inlet airflow and the air outlet airflow generated when the gas driving device 20 operates all pass through the cushion 10, so that the user sitting on the cushion 10 can flow through, so as to ventilate and cool the user. The air inlet hole 13 and the air outlet hole 14 are both formed in the cushion 10, so that the air inlet hole 13 does not need to be additionally formed in the seat or the bed applied by the cushion ventilation structure, so as to simplify the internal structure of the seat or the bed.

[0032] The number of the air inlet holes 13 and the air outlet holes 14 can be one, two or more.

[0033] Specifically, as shown in Figure 1 , the number of the air inlet holes 13 is multiple, and the multiple air inlet holes 13 are arranged in a matrix in the air inlet area 11; the number of the air outlet holes 14 is multiple, and the multiple air outlet holes 14 are arranged in a matrix in the air outlet area 12. The multiple air inlet holes 13 are all in communication with the air inlet end of the gas driving device 20, and the multiple air outlet holes 14 are all in communication with the air outlet end of the gas driving device 20. In this way, the positions available for the air flow to pass through on the cushion 10 can be increased, so as to increase the blowing parts of the user and improve the ventilation and heat dissipation effect. When the user sits on the cushion 10, the body parts of the user will block part of the air inlet holes 13 and the air outlet holes 14. The matrix distribution of the air inlet holes 13 and the air outlet holes 14 can prevent all the air inlet holes 13 and the air outlet holes 14 from being blocked by the body parts of the user, so as to ensure the air flow communication between the upper and lower parts of the cushion 10.
