[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1

[0025] like Figures 1-6 As shown, the air-blowing seat heat dissipation structure in this embodiment is mainly used in car seats. Such seats are typically composed of a backrest 1 and a seat cushion 2. The backrest 1 is usually composed of a sheet metal frame, foam material and surface leather, while the seat cushion 2 is usually composed of a seat cushion suspension spring, foam material and surface leather. The above are common structures in the field and are not further limited here.

[0026] The air-blowing seat heat dissipation structure is mainly composed of a backrest ventilation component on the backrest 1 and a seat cushion ventilation component on the seat cushion 2, thereby forming air-blowing heat dissipation at the backrest and seat cushion positions.

[0027] Specifically, the backrest ventilation assembly includes a first air bag 10 and a first centrifugal fan 20. The first air bag 10 has a first inner cavity for containing air. The first air bag 10 has a plurality of first air outlets 101, which are connected to the first inner cavity. The air outlet of the first centrifugal fan 20 is connected to the first inner cavity. The upper end of the first air bag 10 has a neck 11, and the top of the neck 11 has an air inlet 12, which is inserted into the air outlet of the first centrifugal fan 20.

[0028] The air outlet 12 has a positioning block 13 on its inner side. The edge of the air outlet protrudes outward to form a positioning step 14. The positioning step 14 can pass over the positioning block 13 and abut against the positioning block 13. The positioning block 13 has a right-angled triangular cross section with the inclined surface facing outward and the bottom surface located below the inclined surface. This makes it easy for the positioning step 14 to pass over the positioning block 13 along the inclined surface after insertion and abut against the bottom surface of the positioning block 13 to prevent it from falling off.

[0029] Furthermore, the seat cushion ventilation assembly includes a second air bag 30, a second centrifugal fan 40, and a connecting frame 50. The connecting frame 50 is connected to the second centrifugal fan 40. The second air bag 30 has a second inner cavity for containing air. The second air bag 30 has a plurality of second air outlets 301, which communicate with the second inner cavity. The air outlet of the second centrifugal fan 40 is also connected with the second inner cavity.

[0030] The second air outlet 301 is located on the front of the second air bag 30, and the back of the second air bag 30 is provided with an air inlet pipe 31. The air inlet pipe 31 is generally L-shaped and is connected to the air outlet of the second centrifugal fan 40.

[0031] The connecting frame 50 has a through hole 51, the position of which corresponds to the position of the air inlet 12 of the second centrifugal fan 40. The air inlet 12 of the second centrifugal fan 40 faces the second air bag 30 and there is a gap between them. The connecting frame 50 is provided with a plurality of positioning posts 52. The second centrifugal fan 40 is provided with a plurality of protrusions 41 around its body. The protrusions 41 are provided with positioning holes 42. The positioning posts 52 are inserted into the positioning holes 42.

[0032] The connecting frame 50 is connected to the seat cushion 2 by a fastener 60. The fastener 60 includes a fastening end 61 and an insertion end 62. The fastening end 61 fastens onto the spring of the seat cushion 2, and the insertion end 62 is used to insert into the connecting hole on the connecting frame 50. The fastening end 61 has a hook-shaped structure, and the insertion end 62 has a conical structure. The whole is made of plastic material.

[0033] An adhesive layer is provided on the front side of both the first air bag 10 and the second air bag 30. The adhesive layer is an adhesive layer that does not interfere with the first air outlet 101 and the second air outlet 301. After setting a groove of a corresponding shape in the foam material, the first air bag 10 and the second air bag 30 can be bonded to the groove. The foam material and the surface leather are provided with corresponding holes that communicate with the first and second air outlets.

[0034] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
