Abstract

The utility model relates to a multi-layer fresh keeping box, which is characterized in that heat storage media are filled between a housing and an inner wall. An air pipe is arranged on the top of the box and on the top side walls. The other end f the air pipe is connected with a one-way exhaust valve and an air sac with an exhaust valve. The box has a favorable thermal insulating effect, and carbon dioxides and nitrogen are convenient to be filled in the box. The utility model is characterized in that the utility model has the advantages of simple structure, convenient operation, without power utilization, etc. The utility model can be used in rural regions where the electricity is lacked.

Description

Multi-layer fresh keeping box

The utility model relates to a kind of food preserving antistaling box, is a kind of non-electric multilayer antistaling box of guaranteeing the quality.

At present, the antistaling box of selling on the market of guaranteeing the quality roughly can divide two big classes, and a class is the refrigeration low-temperature antistaling box of guaranteeing the quality, as refrigerator, freezer, also have be with bromine oxygen, the inflation anoxic guarantee the quality fresh-keeping, as bromine oxygen fresh-keeping warehouse or the inflation freshness protection package, have their own characteristics each, the fresh-keeping effect of all guaranteeing the quality, but refrigerator, freezer, the big power consumption of the fresh-keeping investment of bromine oxygen are many, and particularly in the rural area, it is inapplicable often to have a power failure, the fresh-keeping use of aerated plastic bag is inconvenient, can't use thin dish, food.

The purpose of this utility model provides a kind of non-electric multilayer antistaling box of guaranteeing the quality, to solve the vast rural area regional food vegetables fresh-keeping problem of guaranteeing the quality that often has a power failure.

The purpose of this utility model is achieved in that this case is provided with shell and inwall, between shell and inwall, be filled with heat accumulation energy medium, at least one deck dividing plate with holes is arranged in the case, every layer is provided with a hermatic door, on case top or be provided with extraction pipe on the sidewall, the extraction pipe other end is connected with the air bag of one-way exhaust valve and band one-way exhaust valve.

In case, put vegetables, fruit or food during use well, put an amount of carbon dioxide packing or nitrogenize propellant in the bottom or fill into carbon dioxide packing or nitrogen.Shut up the door carefully and use air bags then, make in the case till the air exhaustion, when the external temperature heating, heat accumulation can medium can local deliquescing fusing and heat energy storage, the temperature inside the box influence is little.

This utility model compared with prior art has the following advantages: (1) is simple in structure, and cost is low; (2) fill heat accumulation energy medium good heat-insulation effect; (3) be provided with the air bags structure, be convenient to fill carbon dioxide packing and nitrogen in the case; (4) air bag can manually also fit wellly be stepped on easy to use; (5) not electricity consumption.

Be described further below in conjunction with accompanying drawing:

Fig. 1, the multilayer antistaling box structural representation (analysing and observe attitude) of guaranteeing the quality;

Fig. 2, the multilayer antistaling box structure front elevation (blocking attitude) of guaranteeing the quality;

Fig. 3, one-way exhaust valve component diagram.

Among Fig. 1-3: shell (1), inwall (3) adopts metal or duroplasts to make, between shell (1) and inwall (3), be filled with paraffin, pitch or animal oil heat accumulation energy medium, solid welding has extraction pipe (4) on the case top or on the side wall, by India rubber tube or plastic pipe and one-way exhaust valve (5), air bag (6) is connected as a single entity, air bag (6) is cylindrical, in spring (8) is arranged, the intrinsic up and down metal sheet of spring (8) (7), the outside is surrounded by telescopic folding formula rubber disc, one end is equipped with one-way exhaust valve (5), case internal partition (9) has one deck at least, adopt metal or plastic flagstone with holes to make, itself and inwall flexibly connect or solid welding on inwall, door (10) is step, and pre-small post-large, the step place is provided with 1-3 road packing seal (11), one side is movably connected on the housing (1) by axle (14) support (13), opposite side is provided with Self-locking handle (16), and lock (15) is fixed on the housing (1), and handle (16) is contained on the door.One-way exhaust valve (5) is by pipe shell (5-1), and the solid welding of shell front end has valve gap (5-2), is combined with valve block (5-3), spring (5-4) in the valve gap inboard, and other end screw thread fit has freeing pipe (5-5).
