Description

The ventilation seat cushion

Technical field:

The utility model relates to seat cushion, particularly a kind ofly produces cross-ventilated ventilation seat cushion.

Background technology:

Multiple sky in sweltering heat is sitting in the people on the seat, particularly car steering person for a long time, because the seat cushion stuffiness can be thought that all buttocks is sultry, be perspired, the people is felt sick, even grow the miliaria sore, and influence is normally driven.For addressing this problem, some ventilation mattress have appearred, such as an electric fan is set in seat cushion, but, require guard shield is set on it for avoiding the flabellum pressurized, reduced the elastic performance of seat cushion; Other has a kind of ventilation mattress, at anterior hanging one cloth bag of seat cushion, in the bag air blast is housed, blower outlet communicates with the interlayer of seat cushion, and this structure hinder the thing sense because cloth bag between two leg rear portions, touches to produce with shank, have influence on the regular event of legs and feet, profile is not attractive in appearance yet.

Summary of the invention:

The purpose of this utility model is to have at rule the weak point of technology, provides a kind of and does not hinder and can produce cross-ventilation and ventilation seat cushion easy for installation, good looking appearance with shank.

A kind of ventilation seat cushion of the utility model, seat cushion is connected with back cushion, and ventilation interlayer pad is housed in the seat cushion, it is characterized in that seat cushion and back cushion junction be equipped with tubular footpath flow fan, and dock at the interior interlayer pad rear portion of the air guide hole of this blower fan and seat cushion.

At seat cushion and the disjugal suture logotype of back cushion junction fabric tube in the tubular footpath flow fan of packing into, axially open and slide fastener is housed on the tube face.

Interlayer pad in the above-mentioned seat cushion is made of plastics skeleton shape, and its upper surface has the mesh that communicates with the blower fan air guide hole.

Above-mentioned tubular footpath flow fan is a dc fan, and its housing has the multiple tracks air intake duct, and air intake duct is opened at the top of Blower Housing and two ends.

The good fabric of ventilation that the cover layer of the upper surface of above-mentioned seat cushion is dredged by density constitutes.

Structure of the present utility model as can be seen owing at seat cushion and back cushion junction rear side tubular footpath flow fan is installed, and the dead angle that to be human body be difficult for contacts, this position, thereby the seat person can not hinder the thing sense; The air guide hole of blower fan docks with the interlayer pad rear portion in the seat cushion, makes to produce strong cross-ventilation in the seat cushion, and in time the heat that the human buttock is produced is drained, and is comfortable, nice and cool; The fabric tube slide fastener folding of tubular footpath flow fan is installed, and blower fan is easy for installation.As long as connect automobile power source, the footpath flow fan makes air import from the housing air intake duct during use, discharges from skeleton shape ventilation interlayer pad through the air guide hole of blower fan, is specially adapted to automotive seat and uses, and also can be used for the sofa of office, family.

The specific embodiment:

With reference to Fig. 1-Fig. 4, seat cushion is connected to form by seat cushion 2 and back cushion 1, ventilation interlayer pad 6 is housed in the seat cushion 2, connect material distribution cartridge 3 at seat cushion 2 and back cushion 1 junction disjugal suture, axially open and slide fastener 4 is housed on the tube face, opening is the blower fan material distribution cartridge 3 of packing into when direct current tubular footpath flow fan is installed, and the air guide hole 5.3 of blower fan is inserted in the seat cushion 2 dock with interlayer pad 6 rear portions.Install zip up, good looking appearance.Ventilation interlayer pad 6 is made of plastics skeleton shape, and its upper surface has the mesh 6.1 that communicates with blower fan air guide hole 5.3.

With reference to Fig. 4-Fig. 8, tubular footpath flow fan has the housing 5.1 that has multiple tracks air intake duct 5.11, and air intake duct 5.11 is opened at the top of Blower Housing and two ends, enters so that air is unimpeded.The cylindrical radial-flow impeller 5.2 of packing direct current generator 5.5 in the housing 5.1 into and driving by motor shaft 5.4.Blower fan air guide hole 5.3 is shaped on wind deflector 5.31, and makes one with housing 5.1.The fabric that the cover layer of the upper surface of seat cushion 2 adopts density to dredge is in order to ventilation.
