Description
The utility model relates to a kind of improvement of incubation canteen.
Though traditional incubation canteen has advantage of simple structure, heat insulation effect is relatively poor, function singleness, and seasoning food and beverage use inconvenient simultaneously.
The purpose of this utility model provides a kind of good heat insulating, energy seasoning food and beverage simultaneously, multifunctional fresh-keeping lunch box easy to use.
The utility model is made up of the lunch box 6 in shell 7, loam cake 1 and the shell 7, be provided with vacuum pumpin layer 7 ' and reservoir bed 8 between shell 7 and the lunch box 6 successively, have the top to connect the suction pipe 9 of ball valve 10 in the reservoir bed 8, shrouding disc 4 tops of lunch box 6 are provided with the negative pressure pump 2 that bleeding point is communicated with vacuum layer 7.But lunch box 6 tops are suit dish box 5 also.
The utility model has the advantages that: 1, lunch box, dish box, the reservoir bed, the suction pipe that store foods such as hot boiling water are combined into one, compact conformation, easy to use.2, be provided with the negative pressure pump that is communicated with vacuum pumpin layer, can extract the air in this layer easily out, heat preserving antistaling is effective.3, boiling water that stores in the reservoir bed or hot beverage can be simultaneously as the thermal source that heats food in the lunch box, energy savings.
Accompanying drawing 1 is the utility model example structure schematic diagram.
Describe the utility model in detail below in conjunction with accompanying drawing.
Shell 7 can be made of engineering plastics or stainless steel, and profile is waist shape, so that carry.7 on lunch box 6 and shell are provided with vacuum pumpin layer 7 ' and reservoir bed 8 successively, suction pipe 9 is arranged in the reservoir bed 8, suction pipe 9 vertically is placed in the reservoir bed 8, suction pipe 9 connection ball valves 10 suitable for reading, the delivery port of ball valve 10 and suction pipe 9 linearly the time ball valve 10 close valves, when the delivery port of ball valve 10 and suction pipe 9 center line angles were 45 °, ball valve 10 is opened beverage can be from the suction pipe sucking-off.Dish box 5 is sleeved on lunch box 6 tops, and 5 suitable for reading the holding on the dish 4 of dish box have the negative pressure pump 2 that communicates with vacuum pumpin layer.Draw the pitch brace 3 that pushes away negative pressure pump 2 to discharge with taking out true layer 7 ' interior air.Have on negative pressure pump 2 shells unloading hole 2 ', unloading hole 2 ' unlatching just can open easily and hold dish 4, take out food.The utility model is particularly suitable for mobile personnel such as field work, mine underground work or student and uses.
