Detailed Description

The present invention is described in detail below with reference to the attached drawings:

a seat cushion with a ventilation assembly as shown in figure 1 comprises a ventilation assembly, a filler 2 and a cushion cover 3 which is wrapped outside the filler 2 and the ventilation assembly. The ventilation assembly comprises an upper base plate 11, a lower base plate 12 and a guide pipe 13, wherein the upper base plate 11 is sequentially connected from top to bottom, a plurality of first through holes 111 are distributed on the upper base plate 11, the lower surface of the upper base plate 11 integrally extends to form a vertical hollow guide pipe 13 corresponding to the first through holes 111, the lower base plate 12 is in a flat cylindrical shape and is provided with a cavity 121 positioned inside the lower base plate, a plurality of first air holes 122 penetrating through the cavity 121 are formed in the circumferential direction of the cylindrical surface of the lower base plate 12, a penetrating second through hole 123 is formed in the top surface of the lower base plate 12 corresponding to the guide pipe 13, and the lower end of the guide pipe 13 penetrates through the second through hole. The filling body 2 in this embodiment is made of foaming latex, foam or sponge, the outer contour of which is processed to be adapted to the shape of the cushion cover (for example, the upper and lower sides of the filling body are circular arcs in this embodiment), and a hole for the conduit 13 to pass through is reserved in the production of the filling body 2, and when the filling body is installed, the hole can be filled in the horizontal space between the upper base plate 11 and the lower base plate 12 after being sleeved with the corresponding conduit 13. The side of the cushion cover 3 in the embodiment is provided with a zipper, and when the cushion cover is installed, the cushion cover is sleeved outside the ventilation assembly and the filler 2, so that the installation can be realized, and the cushion cover is limited in the formed space of the cushion cover 3. When a human body sits on the seat cushion, the buttocks are positioned at the top of the seat cushion, namely above the first through hole 111 of the upper base plate 11, and the ventilation assembly at the moment provides a circulation channel which is formed by the first through hole 111, the conduit 13, the cavity 121 and the first air hole 122 and connects the lower part of the buttocks with external air, so that the ventilation and heat dissipation effects on the lower part of the buttocks can be realized, and the ventilation and heat dissipation effects can not be pressed through the supporting action of the disc-shaped upper and lower base plates and the conduit, so that the supporting effect can be continuously and effectively provided.

As shown in fig. 2, in this embodiment, the lower end of the conduit 13 is processed into a guide section 131 with an outer diameter gradually decreasing downward, the guide section 131 is shaped like a circular truncated cone and penetrates downward into the second through hole 123, the diameter of the second through hole 123 is smaller than the maximum diameter of the guide section 131, on one hand, the guide section 131 is conveniently guided and connected by the inclined surface of the circular truncated cone, and the support for the conduit 13 and the upper base plate 12 is formed, on the other hand, only part of the guide section 131 extends into the cavity 121 by the interference effect of the diameter setting, so that the bottom of the conduit 13 is not pressed down to the bottom of the lower base plate 12, and further, a sufficient ventilation space is reserved.

In this embodiment, the side of the guiding section 131 is provided with the second air hole 132 horizontally penetrating through, so as to further increase and increase the path for realizing the ventilation effect by air circulation in the cavity 121, and avoid the problem that the end closed ventilation path fails because the bottom of the guiding pipe 13 is pressed down to the bottom of the lower base plate 12 in an extreme case.

In the present embodiment, as shown in fig. 3, the thickness of the edge of the upper base plate 11 is gradually reduced from inside to outside, and the gradually reduced thickness is in the form of an arc-shaped gradually reduced upper surface, so that better supporting comfort for the buttocks of the upper human body is provided by the arc-shaped surface, and discomfort caused by the over-sharp edge abutting against the human body is reduced. Meanwhile, the gradually reduced thickness enables the edge of the upper base plate 11 to have larger deformation quantity and deformation speed under the same pressure relative to the middle part, so that the pressure of a human body is better adapted, and the uncomfortable feeling of the edge which elastically resists against the human body is reduced.

As shown in fig. 4, in this embodiment, the upper base plate 11 and the lower base plate 12 are rounded rectangles, and the first through holes 111, the second through holes 123 and the conduits 13 are distributed in an array manner in a plurality of circumferences with different diameters around the centroid of the upper base plate 11 in the vertical projection direction, so that the supporting performance of each direction is relatively balanced when the human body sits down from different angles and directions, and the supporting effect is further improved. (in other preferred embodiments the upper base plate 11 and the lower base plate 12 may be rectangular, circular, etc.)

In this embodiment, the cushion cover 3 is further provided with a porous layer 4 above the upper base plate 11, and the porous layer 4 is a porous foamed latex (in other preferred embodiments, it may also be a porous sponge, etc.) which has irregular holes generated during foaming and is processed with vertical holes to enhance ventilation effect. The porous layer 4 is provided with a thickness of 3-5mm so as to provide, on the one hand, a soft and comfortable effect for the human body covering the upper base plate 11 and, on the other hand, not to be too thick to avoid the pressure of the human body pressure and to cause the air-permeable effect of the first through-holes 111 to be blocked.

In this embodiment, the area of the horizontal projection of the porous layer 4 and the side of the filler 2 in contact with the upper base plate 11 is larger than the area of the horizontal projection of the upper base plate 11, so that the edge of the upper base plate 11 is wrapped between the porous layer 4 and the filler 2 as shown in fig. 1, and the edge of the upper base plate 11 is wrapped softly, thereby further improving the riding comfort.

In this embodiment, the upper surface of the upper base plate 11 is provided with a plurality of annular flow guiding grooves 112, and the flow guiding grooves 112 are arranged with the configuration circle corresponding to the circumferential array of the first through holes 111 in this embodiment, so as to connect the first through holes 111 on each circumferential array in a penetrating manner, thereby forming a space for air circulation which communicates the upper ends of the first through holes 111 and exists below the porous layer 4, thereby allowing air to flow conveniently and reducing the influence of the porous layer 4 squeezed by the human body on the ventilation effect.

In this embodiment, the upper base plate 11, the lower base plate 12 and the conduit 13 are the upper base plate, the lower base plate and the conduit made of TPU, and the hardness of TPU in this embodiment is set to 60-65HA, so that the TPU HAs a good supporting performance and can better adapt to the elastic deformation of a human body when the human body sits by setting the TPU to a low hardness and matching with the original high elasticity characteristic of the TPU, and the TPU can completely return to the original state after the human body leaves.

In this embodiment, the cushion cover 3 is a linen cover or a net cloth cover or a chiffon cloth cover, and the linen, the net cloth and the chiffon cloth have lower knitting density and have meshes convenient to ventilate, thereby providing good ventilation effect. The edge of the lower base plate 12 directly abuts against the side of the cushion cover 3, thereby achieving a convenient air exchange capacity with the outside.

The above embodiments are only described for the preferred embodiments of the present invention, and are not intended to limit the concept and scope of the present invention, and the various modifications and improvements made by the ordinary person in the art without departing from the design concept of the present invention all fall into the protection scope of the present invention.
