Abstract

The utility model discloses a plastic cool chair mattress, the shape and the size of which are similar to those of the usual wool or sponge chair mattress, which is mainly composed of a mattress surface (1) and a bottom shell (2) which are tightly matched to form an air chamber (6). A cylinder group (7) which is vertical to the mattress surface is arranged on the mattress surface, and a plane or an arc surface composed of the punctiform heads of cylinders forms on the mattress. An air exhausting vent (9) is arranged between every two cylinders, and the bottom surface of the bottom shell (2) is distributed with a plurality of one-way air inlets (3). An elastic element (11) for enhancing return force is arranged between the mattress surface (1) and the bottom shell (2, and when the mattress surface (1) of the cool chair mattress is pressed, the air chamber (6) ejects upward air current. When a person adjusts the gesture or moves away, the air chamber (6) sucks the air for the ejection of next time.

Description

Pleasantly coal chair mattress

The utility model relates to a kind of daily chair cushion, particularly is suitable for the nice and cool chair cushion that uses in full summer.

The surface of common seat or seat cushion generally is monoblock area and Body contact, and the ventilation condition of skin is very poor, and particularly in summer, the sweat on the skin is many, not volatile, often infiltrates underclothes, sticks on the health, and the people is felt very ill.

Task of the present utility model provides a kind of nice and cool chair cushion, under the preceding topic by other power not, has good cool effect.

For finishing above-mentioned task, the measure that the utility model is taked is: with plastics is material, makes the main part of a shape such as known pad face, and is the pad face with it, the one plastics drain pan that is complementary with the pad face is arranged below the pad face, and both cooperate the back to form one good bubble-tight air chamber.The formed cylinder group of perpendicular cylinder is arranged on the pad face, and the cylinder group preferably is made of one with the pad face.Cylinder can bear enough longitudinal pressures, and after the person was taken fully, cylinder is unlikely to bend.The upper end of cylinder is concordant each other, forms a plane or a cambered surface of being made up of numerous points.Select suitable cylinder spacing, when guaranteeing performance of ventilating, allow the user feel Body contact to be still a plane.On drain pan, have several unidirectional valves, only allow air to enter in the pad.The appropriate location in cylinder hollow crack has a plurality of steam vents on the pad face, and steam vent is led to outside the pad face by air chamber.Drain pan, pad face and the cylinder group on it and the processing and manufacturing of steam vent can be shaped with common plastic processing, as injection moulding or hot pressing etc.When the people is sitting on the nice and cool chair cushion, clothes is pressed on cylinder group upper end, cavity of formation between clothes and pad face.When pad face pressurized was recessed, the air chamber internal pressure increased, and causes unidirectional valve-closing, and air chamber can only because the aperture is little, form the very strong high-speed jet of penetration power by the venting of the hole on the pad face, is blown within the clothing.And mobile along the cavity of clothes and the formation of pad face to all around, strengthened the heat exchange effect.Usually the people is sitting on the chair, often adjust attitude, when health left, recessed pad face depend on elasticity to desire to resile, the air chamber internal gas pressure descends, the pad outer air enters air chamber through unidirectional valve, because circulation area is bigger during unidirectional valve standard-sized sheet, the speed that the pad face resiles is very fast, when sitting back once more, have air-spray again and blow out, so circulate, just finished the function of self-ventilation.

In addition, as consider that the elasticity of plastics is not enough, can install flexible member additional in the air chamber, to strengthen the elasticity of pad face, guarantee that human body leaves nice and cool chair cushion after, have enough power that the pad face is resiled rapidly.

Unidirectional valve on the drain pan can reach requirement with simple mode.For example, open a plurality of slots on the drain pan, on the inner surface of drain pan, lay long and narrow plastic sheeting along each slot, slot is covered, the long limit and the drain pan of film are bonding, and film is attached on the slot freely.

According to the nice and cool chair cushion that such scheme is made, changed the way of contact of common pad face and health, improved gas permeability; Set up the self-ventilation system, can in time blow away the sweat on the skin.The existence of cavity between clothes and the pad face might be passed through brushing of natural wind or electric fan, adds pad face and health and be to contact, and has just obviously improved the gas permeability at seat.With plastics is material of main part, and cost is low, makes easily, and general plastic molding and processing plant can both produce.

Below in conjunction with drawings and Examples the utility model is further described.

Fig. 1 is the cutaway view of an embodiment of the utility model.

Fig. 2 is the enlarged diagram of a unidirectional valve on the drain pan among Fig. 1 embodiment.

Fig. 3 is the local vertical view that amplifies of pad face among Fig. 1 embodiment.

The vertical cutaway view of nice and cool as shown in Figure 1 chair cushion, after matching with drain pan (2), pad face (1) forms air chamber (6), butt joint between the two and sealing means, should be purport with the airtight quality that guarantees air chamber (6), be cylinder group (7) on the pad face (1), leave steam vent position (8) between the cylinder group (7), locate to do by air chamber (6) in steam vent position (8) and lead to steam vent (9) outside the pad face (1), in the present embodiment, cylinder on the pad face (1) is made of one with pad face (1), the spacing of each cylinder is wanted suitably, the people feels the plane that is still that touches when guarantee using, the height of each cylinder needn't be excessive, do not bend when guaranteeing its pressurized, and the position of each steam vent (9) is selected to want suitably.Pad face (1) is gone up cylinder group (7), the amplification plan view of steam vent position (8) and steam vent (9) can be referring to Fig. 3, be made in the unidirectional valve (3) on the drain pan (2), its concrete form is referring to Fig. 2, unidirectional valve (3) is made of air admission hole (4) and plastic sheeting (5), air admission hole (4) is long and narrow rectangle, all lay the plastic sheeting (5) of an elongated shape in air chamber one side of each air admission hole (4), long limit of plastic sheeting (5) and drain pan (2) are located bonding in (10), the long limit of another one and two minor faces are freely, make plastic sheeting (5) open and flat be attached on the air admission hole (4).Also can make the centre of air admission hole (4) latticedly, protrude in air admission hole (4) in addition to prevent that pressure in the air chamber (6) is depressed into plastic sheeting (5).Among air chamber (6), also installed several flexible members (11) additional, flexible member (11) acts directly between pad face (1) and the drain pan (2), and this is in order to strengthen the back stretch of pad face (1).
