Abstract

The utility model relates to an automatically inflating sleeping mattress, which is composed of a piece of nylon cloth which coats a sponge and an air nozzle. Because the waterproof nylon cloth with dense air property coats the sponge with air holes and in addition, a quantity of air enters the sleeping mattress, the utility model has favorable heat insulation effect. The automatically inflating sleeping mattress is suitable for outdoor cold camp or cold rooms. The flexibility can be adjusted at any time. When used, the automatically inflating sleeping mattress inflates automatically so that users feel comfortable. When not used, the automatically inflating sleeping mattress can be reeled and pressed to deflate. The volume of the sleeping mattress shrinks with the deflation. Thereby, the effects of convenient storage and carrying are achieved. Therefore, the utility model has the advantages of simple structure, reasonable design, wide purpose, convenient operation, etc.

Description

Automatic air-filling bed mattress

The utility model relates to a kind of indoor outer bed that uses.

General bed mostly is to make with nylon fiber cloth coating cotton-wool or feather, does not inflate exhaust structure, and flexibility is undesirable, and the big collection of volume is carried very inconvenient.

In order to overcome above-mentioned shortcoming, the utility model proposes a kind of new type auto inflatable bed, utilize nylon cloth to coat leachy sponge, and be equipped with valve at edge, during use valve to be opened, bed just can be inflated automatically.Nylon cloth with anti-watertight gas add leachy sponge and enter some air in the bed make the utility model produce very good warming with every cold effect, and can adjust the pliability of bed, make its softness comfortable, not the time spent exhaust of exerting pressure, volume-diminished is convenient to collection and is carried.

Now conjunction with figs. is described the structure and the using method of the utility model automatic inflation type bed in detail.

Fig. 1 is an automatic inflation type bed structural representation;

Fig. 2 is valve inflation schematic diagram;

Fig. 3 is for closing the valve schematic diagram;

Fig. 4 is the valve exhaust schematic diagram of exerting pressure.

In above-mentioned accompanying drawing: 1 is nylon cloth; 2 is foam-rubber cushion; 3 is valve; 4 is the non-return screwed pipe; 5 is the valve seat; 6 is passage; 7 is knob.

The automatic inflation type bed coats foam-rubber cushion 2 by nylon cloth 1 as shown in Figure 1, and in its corner portion valve 3 formations is set.As shown in Figure 2, valve is made of non-return screwed pipe 4, valve seat 5, and has some passages 6 in non-return screwed pipe 4 bottoms.For safe and convenient to use, on copper non-return screwed pipe 4, be provided with the knob 7 of plastic production.

Rotate valve non-return screwed pipe 4 during use earlier, outside air enters in the foam-rubber cushion 2 by passage 6, as shown in Figure 2, this moment, foam-rubber cushion 2 absorption outside airs expanded naturally, after foam-rubber cushion 2 reaches capacity state, non-return screwed pipe 4 is screwed, promptly close passage 6, make the interior air of bed leak, as shown in Figure 3 because of weight, this moment, no matter the user did uses such as bed, bolster, cushion or back cushion with it, all can feel more soft comfortable.Finish using, when desire collection bed, non-return screwed pipe 4 is back rotated, as shown in Figure 4, this moment is outer to clamp down on bed, promptly folds or furls bed, and foam-rubber cushion 2 interior air are leaked by passage, the bed volume dwindles thereupon, carries effect and reach to be convenient to collect.

The utility model has the following advantages:

1, waterproof, softness, safe, comfortable.

2, have warming every cold special-effect.

3, exert pressure after the exhaust, volume-diminished is convenient to collection and is carried.

In sum, automatic inflation type bed of the present utility model, its structure is simplified, and is reasonable in design, of many uses, easy to use, really is a novel fine piece of writing.
