Abstract
The utility model relates to an air cooling seat cushion. The seat cushion part and the back cushion part are of inner-empty double-layer structure. The layer which contacts with the chair is the outer layer made of soft material and the layer which contacts with the person is the inner layer with a net structure. Between the outer layer and the inner layer, an empty cavity is formed which is supported and separated by a plurality of supporting columns. The empty cavity is provided with a ring porous discharging air pipe which is communicated with a sending air pipe. The sending air pipe extends outside of the seat cushion part and the back cushion part and is communicated with an electric air pump. When the utility model is used, the electric air pump power is connected and the electric air pump will compress the air. The compressing air will enter the discharging air pipe of the seat cushion part and the back cushion part by two sending air pipes and will be discharged by a plurality of discharging air ports of the discharging air pipe. The empty cavity of the seat cushion part and the back cushion part will produce a compellent air flow which can take away the heat produced by the person to achieve a cooling objective. By changing the valve the sair supply state can be adjusted to the state of a single air supply of the seat cushion part or a single air supply of the back cushion part or a simultaneous equivalent air supply of the eat cushion part and the back cushion part or a simultaneous unequal air supply of the eat cushion part and the back cushion part based on the requirement of the persons.
Description
Technical field
The utility model relates to a kind of seat cushion, mainly is the air-cooled seat cushion that can use to body temperature lowering in summer.
Background technology
Seat cushion is people's articles for daily use; be used in many places such as house, office, vehicle drive widely; present seat cushion plays the protection seat often or increases comfortableness; to use in the majority winter; the cool chair cushion that use summer is woven into network structure by fritter bamboo wood, stone material WARP-KNITTING substantially; the also useful plastic injection-moulded structure that reticulates utilizes cancellated gravity-flow ventilation to dispel the heat.
Such cool seat cushion has the following disadvantages: because the contact area of human body and seat cushion is big, human body and orientation of chair all can't ventilate, ventilation has only by the narrow slit of seat cushion network structure and realizes from the seat cushion side, effect of natural ventilation is poor, even at air conditioner surroundings, because human body closely contacts with seat cushion, it is hot that the contact-making surface of human body and seat cushion also can be felt because ventilation effect is bad, particularly to needs for a long time the personnel of hot environment sitting work, for example automobile driver etc. can not play cooling-down effect.
The utility model content
The purpose of this utility model provides a kind of air-cooled seat cushion of realizing human body and seat cushion contact-making surface are lowered the temperature by forced-air blast to remedy the deficiencies in the prior art in the seat cushion network structure.
The purpose of this utility model is achieved in that air-cooled seat cushion, comprise seat cushion part and back cushion part, seat cushion partly with between the back cushion part is connected with hinge, empty double-decker in seat cushion part and back cushion partly are, what contact with seat is outer, outer by leather, flexible materials such as bafta are made, to avoid scratching seat surface, what contact with human body is internal layer, internal layer is a network structure, by bamboo, gas permeable materials such as rattan plaited fabric or netted plastic are made, and form cavity by many support columns isolation between internal layer and the skin, are mounted with exhaust duct in the cavity, have the many places vent on the exhaust duct, exhaust duct is communicated with ajutage, and ajutage stretches out outside seat cushion part and the back cushion part, is communicated with electric air pump.
During use, connect the electric air pumping source, electric air pump compresses air, compressed air enters the exhaust duct of seat cushion part and back cushion part by two ajutages, discharge by many places vent on the exhaust duct, make in seat cushion part and the back cushion cavity partly and produce enforceable circulation of air, take away the heat that human body produces, reach the purpose of cooling.
As preferably, exhaust duct is a loop configuration, to guarantee seat cushion part and back cushion part air draft effect on than large tracts of land and all directions.
As preferably, can increase conversion valve at ajutage and electric air pump, conversion valve is the gas circuit valve of one-to-two, connected mode is that the ajutage of seat cushion part and back cushion part is connected on respectively on two air outlets of conversion valve, conversion valve can be controlled the size to two air outlets switchings or air output, and the air inlet of conversion valve is communicated with electric air pump by blast pipe.
Electric air pump can be selected the motor of different rated voltages according to different environments for use, for example, uses the 220V alternating current generator in family or working environment; Use in vehicle, select the 12V direct current generator, motor power is connected with vehicle power supply by the cigar lighter of vehicle.
By implementing the utility model, make the gravity-flow ventilation of original cool seat cushion change into mandatory ventilation, greatly improved the effect of ventilating, improve cool effect, and can carry out the inequality air-supply to the buttocks and the back of human body by conversion valve control, strengthen the comfort of human body.
The utility model is further described by embodiment below in conjunction with accompanying drawing.
