Problems solved by technology

These two ventilation devices will cause great damage to the car seat sponge cushion. After a long time of use, the surface of the cushion may collapse, and the installation is very complicated and time-consuming. In addition, the air is uneven, which affects the comfort of the ride. sex
In addition to the common problems of these two patents, the former patent has a foreign body sensation and vibration at the fan, and the latter patent has a large air volume loss, which makes the end air volume small and correspondingly increases energy consumption.

Embodiment 1

[0033] Please see first figure 1 , figure 1 It is a structural schematic diagram of the first embodiment of the seat ventilation device of the present invention. As shown in the figure, a seat ventilation device includes a foam layer 3 and a ventilation duct 4. The air outlet 7 of the ventilation duct 4 is embedded in the foam On the lower surface of the cotton layer 3, the air inlet 6 of the ventilation duct 4 is externally connected to the fan system 5. The ventilation duct 4 is an I-shaped cavity, and an air inlet 6 is arranged on one side of the I-shaped cavity, and a plurality of air outlets 7 are arranged on the other side. The air inlet 6 is located in the middle of the I-shape, and a plurality of air outlets 7 are evenly distributed on both sides of the I-shape.

Embodiment 2

[0035] see figure 2 , figure 2 It is a structural schematic diagram of the second embodiment of the seat ventilation device of the present invention. As shown in the figure, the ventilation duct 4 in this embodiment is in the shape of an octagon, and is composed of a routing adapter and eight branch pipes. The central side of the routing adapter is provided with an air inlet 6, and one end of the branch pipe is connected to the routing pipe. The adapters are connected, and the other end is used as the air outlet 7. When in use, it is embedded in the lower surface of the foam layer 3, and the directions of the air outlet 7 and the air inlet 6 are opposite.

[0036] image 3 It is a structural schematic diagram of a ventilated seat of the present invention. As shown in the figure, a ventilated seat includes a seat body leather cover layer 1, a 3D connection layer 2, a foam layer 3, a ventilation duct 4 and a fan system 5. The 3D connecting layer 2 is arranged between the f...

Abstract

The invention discloses a chair ventilation device and a ventilated chair. The chair ventilation device comprises a foam layer and a ventilation pipeline; an air outlet of the ventilation pipeline isembedded in the bottom of the foam layer; an air inlet of the ventilation pipeline is connected with an air blower system. The chair ventilation device and the ventilated chair have the advantages that production cost is lowered, loss of air volume is reduced greatly, foam collapse is avoided after long-term use, the ventilation area / ventilation points are arranged flexibly, no foreign body sensation and vibration sensation is caused, and users can choose ventilation position optionally.

Description

technical field [0001] The invention relates to the technical field of car seats, in particular to a seat ventilation device and a ventilated seat. Background technique [0002] With the continuous improvement of people's quality of life, the requirements for car ride comfort are getting higher and higher, and the ventilation of car seats is an important factor affecting the comfort of car seats. Especially in the summer when the human body is prone to sweating or the weather is hot, it is necessary to help the body surface of the driver and passengers to perspire and refresh. At present, some high-end automobiles on the market already have ventilation functions. The more common one is the layout structure of a seat ventilation device announced by the invention patent CN103042960A. The axial flow fan is placed in it to achieve the purpose of ventilation. Such as patent ZL200720151433.2 discloses a car ventilated seat structure, an H-shaped or U-shaped air groove is dug out...
