Description
Technical field
The invention belongs to food heat-insulation, freshness preserving gadget technical field, be specifically related to a kind of insulation can with inner bag.
Background technology
The food insulation box of prior art, has two kinds usually: first foam thermal insulation (cold) case, it two is hollow blow molding or rotational moulding insulation can.The former is that the engineering plastics usually selecting some to be easy to foam in industry make chest or box, and these materials are short texture after foaming, and very easily adsorb the smell of food and non-easy cleaning and removal, the chest of individual layer is also unsatisfactory in intensity and heat-insulating property.Although the latter can clean, weight large use labor cost is high, the complicated price of manufacturing process is high.
Such as China Patent No. ZL201420053369.4, name is called the utility model patent of " a kind of low-temperature insulation case ", disclose a kind of low-temperature insulation case, comprise casing and case lid, described casing is divided into inner bag and shell, described inner bag can be separated with shell and take out from casing, and it is divided into three parts, i.e. side, base and insulation strip; Described shell is divided into inside and outside two-layer.Water, ammonium chloride and white phosphorus is filled with respectively in described side, base and insulation strip.The left and right sides of described insulation strip uses leaching membrane paper.Described shell internal layer adopts the double glass vacuumized, and skin is PE warm material.Case lid described in this patent and shell adopt identical structural materials.There is some deficiency in this insulation can.Specification sheets according to this patent is recorded, and 1, it " is filled with water, ammonium chloride and white phosphorus in side, base and insulation strip respectively.White phosphorus burning-point is very low, and when reaching uniform temperature, severe friction can spontaneous combustion, and then side and base just form path, and water and ammonium chloride, in conjunction with a large amount of heat of transient absorption, make box house momentary recovery to low temperature environment, ensure the quality of product." obviously, use the danger of white phosphorus self-evident.2, shell internal layer adopts the double glass vacuumized, and skin is PE warm material.Because the compressive property of PE material is poor, yielding and easily break, glassy crisp, if outer pressure-rupturable, will bring disaster upon and inner layer glass, so the compressive property of this structure is extremely unreliable.
Summary of the invention
The technical issues that need to address of the present invention are, poor stability, defect that intensity is low that the low-temperature insulation case overcoming prior art exists, provide a kind of insulation can of safe and reliable, band inner bag that temperature equalization, free from extraneous odour, intensity are high.
The object of the invention is to be achieved by following technical proposals: a kind of band inner bag EPP insulation can, comprise casing, it is characterized in that, casing there is upper cover, casing is built with inner bag, be lined with pallet below upper cover, be placed with ice chest in the middle of pallet, respectively there is the gas channel of several up/down perforations at the middle part of pallet and ice chest; Casing and inner bag and between upper cover and inner bag, be provided with airflow circulating passage, airflow circulating passage comprises the end passage between the downside that is arranged at bottom the wing passage between the medial surface of casing and the lateral surface of inner bag, the upper side being arranged at bottom half and inner bag; The side of casing is provided with heat indicator.

Inner bag pendulum, in casing, is put into food in inner bag, is then covered pallet, and place ice chest in the middle of pallet, then close upper cover, and the cold air of ice chest bulk storage sinks to entering cooling food in food by described gas channel; On the other hand, the heat of food by conducting to sidewall and the bottom of inner bag, then is sent to the periphery of ice chest by wing passage and end passage by air-flow, and the streamed power of gas relies on free convection to be formed, and the gas be namely heated can rise by nature.
As preferably, temperature counts digital display thermometer.
As preferably, described wing passage comprises the straight groove being vertically arranged at box inside face; Passage of the described end comprises the rhombus net form groove being arranged on bottom half upper side, and described straight groove is communicated with rhombus net form groove.The straight groove of sidewall, be beneficial to thermal current rising and form free convection, bottom rhombus net form groove can be communicated with and can improve bottom bending strength and torsional strength.
As preferably, divide in the middle of pallet and be separated with two spaces, in space, be respectively placed with an ice chest.
Can independently use after case lid and box body combinations.
Rear inner bag is used to take out cleaning.
As preferably, casing and upper cover are made up of EPP material, and inner bag is made up of corrosion-resistant steel or PP or PE, and ice chest is made up of PE material, and pallet is made up of EPP material.PE and the PP material of food stage is the packing that existing optimum holds for food, health, heatproof, heat insulation, good toughness; EPP proportion is little, good toughness shock resistance, nonpoisonous and tasteless, environment-friendly degradable.
As preferably, ice chest is made up of box body and lid, and lid and box body pass through ultrasonic welding.
As preferably, casing has a side to be connected with a pair refrigerator pipe joint.Refrigerator pipe joint can connect cold air source forces cooling to box house, and this is necessary when inner bag just put into by food or standing time is more permanent.
As preferably, described refrigerator pipe joint comprises self sealss plug and the self sealss socket corresponding with self sealss plug; Described self sealss plug comprises edge connector and the pipe joint for being connected refrigerator pipe being fixedly connected on edge connector rear end, edge connector front end outer side is the connection-peg being provided with seal ring, conical sealing surface is established at inner chamber position, edge connector front end, the sealing head coordinated with sealing surface is located at described inner chamber position movably, sealing head leading section stretches out the length of edge connector front end face one setting, one end of retracing spring one withstands on the aft end face of sealing head, the other end of retracing spring one withstands on the front end face of described pipe joint, and described inner chamber position is communicated with the central tube of pipe joint; Described self sealss socket comprises socket seat, the leading section of socket seat middle cavity is the plug socket coordinated with described connection-peg, the rear end of described cavity is fixedly connected with the spring perch that center is provided with pipeline, conical sealing surface is established at the position, stage casing of described cavity, the sealing head coordinated with sealing face is located in described cavity movably, and sealing head leading section stretches out the length of one, the bottom surface setting of socket seat; One end of retracing spring two withstands on the aft end face of sealing head, and retracing spring two other end withstands on the front end face of described spring perch, and outside socket seat, butt flange is established at position, stage casing.The advantage that self sealss plug of the present invention and the self sealss socket corresponding with it coordinate is that grafting can be communicated with, and when plug is extracted, socket can be airtight voluntarily, never leaks.
