The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail, to help understanding content of the present utility model.
As shown in Figure 1, but the emergent mattress of a kind of inflation/deflation of the present utility model, comprise and be provided with the sealing plastic bag that fills exhaust inlet non return check valve 14, two layers of plastic thin films up and down 11 at plastic bag, make upper and lower two layers of plastic thin films 11 by many horizontal main hot threads 16 between 12, 12 meltings are sticked together, main hot thread 16 is separated to form the plenum chamber that a plurality of bar shapeds are arranged to whole plastic bag, the shape that described main hot thread 16 broadens for middle narrow two ends, the widest part and plastic bag dual-side remain with certain distance, and main hot thread 16 can not the whole plastic bag of lateral direction penetrating to leave the plenum chamber blow-by gas passage.During inflation as shown in Figure 6 plenum chamber can form gas column side by side, due to narrow in the middle of main hot thread, the gas column diameter is large, and main hot thread two ends broaden, make gas column attenuate in this part, take form as shown in Figure 5 cross-sectional surface be in the middle of the lower slightly W shape surface that meets the ergonomic principle, high both sides, improve the comfortableness while sleeping, middle part highest point 19 corresponding people's spine ditch in Fig. 5, the partially inboard part correspondence of both sides highest point 18 zone of letting go.
As shown in Figure 1, every main hot thread 16 both ends are expanded gradually and are divided fork, the auxiliary heat zygonema 16a vertical with main hot thread 16 arranged going out fork minute end, this triangular structure as shown in Figure 1, can realize the narrow effect in wide centre, main hot thread two ends, but required little energy during due to the little heat seal of heat seal area, and after heat seal, cooling curing is fast, to avoid producing undesirable distortion.Leave gap between the auxiliary heat zygonema 16a of adjacent main hot thread part end, to form the air access way.
Plastic bag can form for two piece plastic films 11,12 overlap by four limit heat-sealings.The material that plastic sheeting 11,12 is the compound or coextru-lamination of dry type forms, can adopt two monolithics, also can adopt the cylindrical plastic film of Blown Film, only need form with hot-sealing line 17 heat-sealings at the two ends of cutting, along described upper and lower two layers of plastic thin films both sides of the edge, be provided with the longitudinal heat seal line 15 that upper and lower two layers of plastic thin films heat seal is bonded together.The existence of longitudinal heat seal line 15 make while adopting cylindrical plastic film for avoid in emergent mattress production process with use procedure in, contact with delivery vehicle due to end face and wearing and tearing that the sharpening at edge produces, improve the product row yielding in production process and can extend its service life.
Longitudinal heat seal line 15 extends dentation hot thread 15a towards the direction of described horizontal main hot thread 16, leaves gap between dentation hot thread 15a and main hot thread 16 and forms the plenum chamber blow-by gas passage.Like this after inflation due to the existence of main hot thread 16 with dentation hot thread 15a, mattress is the gas column of arranging one by one as shown in Figure 6, can be collapsed, collapse and can form air pillow 12 by an end, without standby pillow again, and height and width can according to reel the number and arbitrarily adjust, adapt to different human needs.Main part 26 is for the support of trunk.
Be understandable that, for reaching the W surface configuration, can also adopt point-like heat seal mode to replace main hot thread 16, by controlling the position of heat seal point, close regional and realize in other at the auxiliary heat zygonema 16a near zone that is arranged in substantially Fig. 1.But point-like heat seal mode may have the danger be torn when the blowing pressure is larger, and be difficult for resembling the convolution of mode shown in Fig. 6 after inflation.
The length dimension L of described plastic bag before not blowing thinks that 2.7～3.5 meters are advisable, and what width dimensions W was more satisfactory is to be 0.6～0.7 meter.Blow so aerobic after, size just in time can meet most people's height demand.Can certainly widen, widening width is finally the integral multiple of aforementioned W, to adapt to many people, shares needs.
In the utility model to the improvement of inlet non return check valve 14, In Figure 2-4, inlet non return check valve is two and is clipped in the upper and lower two layers of plastic thin films 11 of described plastic bag, two overlapping narrow strip plastic sheetings 21 between 12, 22, narrow strip plastic sheeting 21 links together by hot thread 17 heat seals as shown in Figure 2 and between the plastic sheeting 11 of adjacent formation plastic bag, narrow strip plastic sheeting 22 also links together by the hot thread heat seal as shown in Figure 2 and between the plastic sheeting 12 of adjacent formation plastic bag, and two narrow plastic sheetings 21, between 22, the part of corresponding hot thread 17 can not be bonded together.Article two, narrow strip plastic sheeting 21,22 edges are heat sealing at together by twice hot-sealing line 20 as shown in Figure 4, to form tubular turnover gas passage.Between these two narrow strip plastic sheetings, 21,22 edge twice hot-sealing lines 20, distance is the wedge shape narrowed down gradually to bag middle part direction.Such benefit is easily to insert hollow pipe, the pipe that simultaneously wedge-like portion can adapt to different-diameter with and the pipe end between be adjacent to, also be conducive to air inlet.
As shown in Figure 3,4, between two narrow strip plastic sheetings 21,22, bond together when avoiding heat seal, and be convenient in when inflation inlet non return check valve entrance point smooth opening, be printed with high temperature resistant printing ink layer 23 so that can not be to stick to one in heat seal between the two have one at least in two narrow plastic sheetings 21,22 above, the passage of using to form intake and exhaust.High temperature resistant printing ink refers to and can be greater than the plastic sheeting heat-seal temperature by tolerable temperature.
As shown in Figure 3, described printing ink layer 23 extends and substantially to become T shape to the plastic bag direction in plastic sheeting 21 centre positions, and the end, extension narrows down and be wedge shape, to form the structure that outer imperial palace is little, is conducive to inflation.Printing ink layer is no more than 1/2 of narrow plastic sheeting in the print range of narrow plastic sheeting length direction.So not two narrow plastic sheetings of part of printing-ink easily by be adjacent to together to improve airtight effect from absorption affinity.Due to two plastic sheetings 21,22 and plastic bag, be not bonded together simultaneously, as shown in Figure 2, unsettled part in the mattress cavity is subject to the double action of effect and the mutual absorption between plastic sheeting 21,22 inner surfaces of mattress inner chamber body air pressure, makes the air only import but no export.
For improving the absorption ability certainly of the plastic sheeting 21,22 that forms inlet non return check valve 14, as shown in Figure 7, described two narrow plastic sheetings 21,22 are all Polar Crystal Slabs, to be compounded with self-adhesive layer 5 in a side of PE base material 6, self-adhesive layer 5 is the PE that are added with maleic anhydride graft in EVA, and two narrow plastic sheetings the 21, the 22nd, be oppositely arranged with self-adhesive layer one side.This structure absorption affinity is even, is difficult for existing watermark or bubble during absorption, improves obturation effect.
The PE base material, from the compound side of self-adhesive layer, being followed successively by LDPE layer 4, HDPE layer or MLDPE layer 3, and LDPE layer 2, containing the anti-aging LDPE layer 1 of antioxidant.The benefit of this multi-layer compound structure is by HDPE layer or MLDPE layer 3 to improve the rigidity of film, be conducive to film and keep smooth, the raising of flatness not only is beneficial to printing, the heat seal of accurately carrying out high temperature resistant printing ink and cuts etc., also is conducive between plastic sheeting 21,22 fit tightly without bubble etc.
During use as shown in Figure 6, hollow tubing conductor 24 is inserted between two plastic sheetings 21,22 of inlet non return check valve 14, because having ink layer, initiating terminal therefore is easy to insert, can utilize mouth or inflator etc. to inflate by air hose, while inflating during air pressure plastic sheeting do not have ink layer originally fit together partially open, in the mattress cavity, inflate, the absorption affinity on surface between this pressure disappearance plastic sheeting when inflation pauses, reach the mattress inner air pressure plastic sheeting overhanging portion is fit together rapidly, prevent that air from flowing backwards away.If hollow tubing conductor is inwardly inserted and exceeds inlet non return check valve always, in mattress, air can be discharged by conduit, realizes the venting function, after venting, mattress can be folded and roll in order to use next time.
In the utility model, " hot-sealing line " refers to the hot thread that two plastic sheeting edges are carried out to heat seal, by the mold pressing heat seal, to be formed so that be sticked together between two layers of plastic thin films, because the purpose of this part heat seal is two plastic sheeting edges of sealing, do not there is the hot thread of airtight effect for distinguishing other parts, adopted " hot-sealing line " this name.
