[0021] like Figure 1 As shown, seat foam 5 covers the seat frame, and back panel 2 is fixed to the side of seat foam 5 away from the human body. An installation space is formed between back panel 2 and seat foam 5. An air guide assembly and fan body 1 are installed within this space. The air guide assembly includes a ventilation bag 4 and a fixing plate 3. The ventilation bag 4 is fixed to seat foam 5 and is made by sealing and welding the edges of two layers of TPU film. Multiple first ventilation holes are formed on seat foam 5. Second ventilation holes are formed on the TPU film near seat foam 5 corresponding to the first ventilation holes. A first ventilation opening for connecting to the fan body 1 is formed on the TPU film away from seat foam 5. An air guide layer is also filled between the two TPU films. The air guide layer uses a porous 3D spaced mesh fabric. The air guide layer supports the two TPU films and balances the gas pressure inside the ventilation bag 4.

The first elastic rivet 101 is passed through the connecting hole 31 and the first mounting hole 11 in sequence, so that the first locking groove engages with the connecting hole 31. The first protrusion 111 and the first mounting hole 112 are connected in sequence. A limiting part 112 abuts against both ends of the first mounting hole 11, thereby mounting the fan body 1 onto the fixing plate 3; the first elastic rivet 101 passes through the inside of the elastic member 204, so that the first limiting part 112 and the first claw 113 abut against both ends of the elastic member 204, thereby fixing the elastic member 204 onto the fan body 1; through the above arrangement, the fixing plate 3, the fan body 1 and the elastic member 204 can be relatively fixed under the action of the first elastic rivet 101, and the elastic member 204 can effectively prevent the fan body 1 from contacting the back plate 2 and block the transmission of vibration between the two.

Furthermore, the first elastic bladder 201 has a first opening at one end near the back plate 2, and the first opening has at least one first notch 205 circumferentially formed. The opening can abut against the back plate 2. When the first elastic bladder 201 is compressed or stretched, air can enter and exit the interior of the first elastic bladder 201 through the first notch 205, preventing the first elastic bladder 201 from adhering to the back plate 2. With the above arrangement, the fixing plate 3 and the fan body 1 can be relatively fixed under the action of the second elastic rivet 102, and the first elastic bladder 201 and the fan body 1 can be relatively fixed under the action of the third elastic rivet 103. At the same time, the first elastic bladder 201 can effectively prevent the fan body 1 from contacting the back plate 2 and block the transmission of vibration between the two.

The second elastic bladder 202 and the snap-fit ​​post 141 are integrally formed and can both be made of rubber. The snap-fit ​​post 141 extends along the axial direction of the fan body 1. When the snap-fit ​​post 141 is inserted into the fourth mounting hole 14, the snap-fit ​​post 141 can be snapped with the snap-fit ​​block, thereby fixing the second elastic bladder 202 to the fan body 1. Further, the second The elastic bladder 202 has a first opening at one end near the back plate 2. The first opening has at least one first notch 205 circumferentially formed. The first opening can abut against the back plate 2.

With the above arrangement, the fixing plate 3 and the fan body 1 can be relatively fixed under the action of the self-tapping screw 104. The second elastic bladder 202 and the fan body 1 can be relatively fixed under the action of the snap-fit ​​post 141 and the snap-fit ​​block.
