Description

A kind of freezing express box

Technical field

The utility model relates to a kind of freezing express box, is specifically related to the low-temperature receiver of setting in express box and the hermetically-sealed construction of deep freezer.

Background technology

At present, shopping online becomes the shopping mode of people's general choice gradually, and correspondingly express delivery industry is also more and more flourishing, except can delivering the traditional commodities such as dress ornament, electronics, books, fresh food, frozen food field have been related to, such as fruit, birds, beasts and eggs, fresh meat, cold drink etc.Because fresh food, frozen food need to solve problem fresh-keeping and insulation, so such commodity must be used the van cooler transportation in transit, when food arrives in client's hand, still can there is desired freshness and temperature.

For frozen food, as frozen meat, frozen fish, seafood, boiled dumpling etc., only refrigeration is inadequate, because refrigerant temperature is often above zero, under such temperature conditions, frozen food can thaw gradually, reduces food quality, for the storage temperature of frozen food, should remain on below zero.

Although van cooler can solve frozen food transport with delivery process in the insulation problem, the food outer packaging is but ordinary packing, does not have heat insulation function.When food is delivered in client's hand, client's addressee ground may be work unit, although the client can take away food after work, due to the equipment that does not now there is further preservation as refrigerator etc., food can not be placed under suitable environment and deposit, also can affect the quality of food.Perhaps food is delivered to the place of reception room one class, and the client does not get for a long time, and food will inevitably go bad, and these factors have all limited the development of express delivery industry at field of food.

The utility model content

For problems of the prior art, the utility model provides a kind of freezing express box, casing and the case lid of this express box are provided with heat-insulation layer, be provided with scientific and technological ice and dry ice in case as low-temperature receiver, science and technology ice can play the effect of refrigeration, the dry ice cooling rate is fast, can play freezing effect.This express box can realize that by these two kinds of low-temperature receivers the temperature inside the box maintains below zero, if when food is put into be freezing state, can remain for a long time freezing, if when food is put into be non-freezing state, can realize fast freezing.

The purpose of this utility model is achieved through the following technical solutions:

A kind of freezing express box, comprise casing, case lid, between casing and case lid, is provided with buckle, it is characterized in that, the edge that casing and case lid fasten is identical L-type mutually, is provided with the magnetic rubber bar on described edge; Be provided with the low-temperature receiver of cooling on described casing and cover wall, the low-temperature receiver on described cabinet wall is some bags of scientific and technological ice, and the low-temperature receiver on described cover wall comprises scientific and technological ice and dry ice, on described case lid, also be provided with can exhaust outside case blowdown valve.

Further, the skin of described casing and case lid is provided with supporting layer, and internal layer is provided with heat-insulation layer, or adopts the sandwich construction of supporting layer, heat-insulation layer and supporting layer.

Further, described low-temperature receiver adopts velcro to be arranged on the inwall of casing and case lid.

Further, be provided with electronic thermometer on described casing.

The utlity model has following positive technique effect:

Freezing express box of the present utility model is used for depositing the freezing food of needs, do not need express box is positioned in the equipment such as refrigerator and can realize the freezing of food, there is temperature retention time long, the characteristics of good airproof performance, the express delivery industry is used this freezing express box to deliver food, be not subject to the environmental limit of addressee ground, widened business scope, improved service quality.

Fig. 2 is left view of the present utility model;

Fig. 3 is A section enlarged view in Fig. 2;

Fig. 4 is front view of the present utility model;

Fig. 5 is B section enlarged view in Fig. 4.

In Fig. 1-5: 1. casing, 2. case lid, 3. blowdown valve, 4. buckle, 5. low-temperature receiver, 6. supporting layer, 7. heat-insulation layer, 8. magnetic rubber bar.

The specific embodiment

Be to reach technological means and the effect that predetermined utility model purpose is taked for further setting forth the utility model, below in conjunction with accompanying drawing and preferred embodiment, structure of the present utility model, workflow be described in detail as follows.

Be one of the utility model embodiment as shown in Figure 1, Figure 2, Figure 3 shows, in this embodiment, freezing express box comprises casing 1, case lid 2, between casing 1 and case lid 2, is provided with buckle 4, is used for fastened housing 1 and case lid 2.

As shown in Figure 2 and Figure 3, the edge that casing 1 and case lid 2 fastens is identical L-type mutually, is provided with magnetic rubber bar 8 on described edge, and magnetic rubber bar 8 is Z-shaped, adopts the fastening edge of this structure can improve the sealing effectiveness of freezing express box.

As shown in Figure 2, be provided with the low-temperature receiver 5 of cooling on the inwall of casing 1 and case lid 2, the low-temperature receiver 5 on casing 1 inwall is some bags of scientific and technological ice, and the low-temperature receiver 5 on case lid 2 inwalls comprises scientific and technological ice and dry ice.

Science and technology ice is a kind of novel ice bag substitute products, and the time that maintains freezing state is long especially, and can repeated usage, and scientific and technological ice can play the effect of refrigeration.Dry ice is dry ice, and during volatilization, cooling rate is fast, can play freezing effect, is the cooling agent that field of food is commonly used.This express box can realize that by these two kinds of low-temperature receivers the temperature inside the box maintains below zero, if when food is put into be freezing state, can remain for a long time freezing, if when food is put into be non-freezing state, can realize fast freezing.

Low-temperature receiver 5 adopts velcro to be arranged on the inwall of casing 1 and case lid 2, for convenience detach.

Because dry ice volatilization can produce a large amount of gas, can not use dry ice in closed environment, so freezing express box of the present utility model on case lid 2, also be provided with can exhaust outside case blowdown valve 3, as shown in Figure 4, Figure 5.When the case internal gas pressure is elevated to certain pressure, blowdown valve 3 automatically starts and carries out pressure release, maintains the safe condition of case internal gas pressure.In order further to improve safety factor, two or more blowdown valves 3 can be set on case lid 2.

As shown in Figure 2, the skin of casing 1 and case lid 2 is provided with supporting layer 6, and internal layer is provided with heat-insulation layer 7, and casing 1 and case lid 2 can also adopt the sandwich construction of supporting layer, heat-insulation layer and supporting layer.

In the utility model, also be provided with electronic thermometer on casing 1, be used for monitoring the temperature in case.

Above describedly just for the utility model is described, is construed as the utility model and is not limited to above embodiment, meet the various flexible form of the utility model thought all within protection domain of the present utility model.
