Description

The pressure lunch boxes of using more

The utility model relates to a kind of cooking utensil, is a kind of pressure lunch box of using more.

Though the advantage of family expenses pressure cooker more and more is familiar with by people now, but because its shape and structure are limit, but not portable going out, and it is little, easy to carry and still can make the cooker of food under the condition of no burning things which may cause a fire disaster at present to be that field work or march, tourism etc. all need a kind of volume, but pressure cooker but is difficult to satisfy above-mentioned requirements.

The purpose of this utility model provides a kind of easy to carry, can have or not the pressure lunch boxes of using of cooking the prepared food thing under the condition of burning things which may cause a fire disaster again in the open air more.

The purpose of this utility model is achieved in that the housing of this lunch box is oblate reducing box body, and lid compresses seal cover in being, is provided with locker, pressure regulator valve and safety valve on lid, is provided with burning piece support below box body.

Narrate embodiment of the present utility model according to accompanying drawing below.

Fig. 1 uses the structural representation of pressure lunch box more for the utility model.

Fig. 2 is the vertical view of Fig. 1.

Fig. 3 is the structural representation of locker.

Fig. 4 is the vertical view of Fig. 3.

Fig. 5 is the structural representation of pressure regulator valve.

Shown in Fig. 1-2: the housing 1 of this lunch box is oblate reducing box body, so-called oblateness be exactly two of housing 1 be semicircle.The centre is a rectangle, and reducing is exactly the convex edge that the lunch box mouth all forms inside contraction.Lid 2 compresses seal cover in being, lid 2 and housing 1 are the same to be oblate.On lid 1, be provided with locker 3, pressure regulator valve 4 and safety valve 5.A circle U type seal groove is made at the edge of lid 2, and O type O-ring seal 6 is set in the U type groove, and cushion rubber 6 contacts with lunch box reducing convex edge and forms sealing.The lid lid method that compresses lid 2 in this is, earlier the pressing plate of locker 3 on the lid 2 opened during loam cake, and lid 2 puts in the housing 1 at a slant then, cushion rubber 6 aligning reducing convex edges.Pressing plate when loosing one's grip on the lid 2 and cushion rubber 6 just are clipped in the middle the convex edge, thereby make whole lid 2 outstanding lids in the lunch box reducing.Like this, when heated shell 1, the bulbs of pressure that produced in the housing 1 are big more, and lid 2 is tight more with the sealing of housing 1, to reach the purpose of high pressure heating.Safety valve 5 on the lid 2 is exactly the low melting point flame-arrester vent plug that adopts present pressure cooker general, in case cause the superpressure explosion accident because of pressure regulator valve 4 is malfunctioning.In order to protect locker 3, pressure regulator valve 4 and the safety valve 5 on the lid 2, and easy to use, can also cover a rice bowl 7 on the lid 2, rice bowl 7 can adopt metal or plastics to make, and its body cooperates with lid 2.At two of housing 1, by rivet one self-locking bale handle 8, overlap bakelite on the crossbeam of bale handle 8, and have concurrently compress, the fixedly effect of rice bowl 7.Below housing 1 folding rack 9, can not only support housing 1 when support 9 launches and can also form a support of putting solid combustion piece 10.

As shown in Figure 3-4: locker 3 is to constitute like this: it has the little outer casing frame 11 of a rectangle, has the convex edge below the shell frame 11, with rivet 12 convex edge is riveted on the lid 2.Shell frame 11 bilateral symmetry are provided with two hinges 13, hinge 13 hinged two block pressur plates 14.Malleation is on the reducing convex edge of lunch box housing 1 when pressing down for the overhanging end of pressing plate 14, and then insert in the draw-in groove that is stuck in last item 15 lower ends in the shell frame 11 the inner of pressing plate 14.Be provided with stage clip 16 below the last item 15, the lower end of stage clip 16 withstand on lid 2 above.The upper end of last item 15 is provided with knob 17.Put the hollow bolt 18 of tape spool shoulder at last item 15 middle parts, bolt 18 lower ends withstand on above the draw-in groove of last item 15, and bolt shaft shoulder part withstands on the last inwall of frame 11.The part that bolt 18 stretches out shell frame 11 connects tapped handle 19 handles 19 and is disc, the center is last item hole and groove, clamp shell frame 11 shell walls with the shaft shoulder of bolt 18 handle 19 lower ends, thereby bolt 18 and handle 19 are fixed on the shell frame 11, the method of operating of locker 3 is: hamper covered 2 o'clock, prop up knob 17 with thumb, forefinger and middle finger are clipped under handle 19 disks, push and promote last item 15, stage clip 16 and pressing plate 14 the inners, make about 45 ° of its overhanging end perk because of the inner of pressing plate 14 presses down like this.After lid 2 inserted housing 1 contraposition, the pressing plate 14 of loosing one's grip just rebounded and has clamped the reducing convex edge of housing 1.

As shown in Figure 5: pressure regulator valve 3 is to be made of valve body 20, regulator bolts 21, spool 22, spring 23, seal spool pad 24, steam discharge bolt 25, valve seal pad 26, steam discharge nut 27 and pressure release handle 28.Wherein valve body 20 upper ends regulator bolts 21 by thread connection, and what pass from the axis hole of regulator bolts 21 is spool 22.The lower end of spool 22 is established spring 23 for having shaft shoulder taper shape between the shaft shoulder of regulator bolts 21 and spool 22.Be seal spool pad 24 below the conical end of spool 22, sealing gasket 24 is set in the upper end of steam discharge bolt 25, and constitutes concentric exhaust hole with the steam discharge bolt.Bolt 25 is a kind of upper coarse and lower fine reducing bolts, and its particle size is screwed on the internal thread of valve body 20 lower ends, and sealing gasket 26 is pressed in above the lid 2 below particle size, and lid 2 is passed in thin footpath, twists in steam discharge nut 27.Steam discharge nut 27 radially is provided with four exhaust holes, and communicates with the exhaust hole of bolt 25.During normal the use, when the vapour pressure in the lunch box surpassed the pressure-bearing value of this valve, steam just can be through steam discharge nuts and bolt exhaust hole jack-up spool, and discharges in the exhaust hole of valve body side.If think to let out rapidly vapour pressure, as long as just but mention pressure release handle 28 pressure releases that are located at spool 22 upper ends except that in the lunch box.If want supercharging in lunch box, as long as adjust the drafts of bolt 21.

The utility model volume is little, and is in light weight, and compact conformation is easy to carry.It has not only solved the problem of cooking of no burning things which may cause a fire disaster, but also has reduced the trouble of open-air band pot inconvenience.It is again the fast pressure cooker of cooking having under the condition of burning things which may cause a fire disaster simultaneously, and is a lunch box that has rice bowl under the situation that pot is arranged.
