All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1 to 5, in the embodiment of the present invention, a polyethylene food bag comprises a bag body 1, a placing bag 2 is fixedly connected to an inner wall of the bag body 1, a water storage tank 3 is formed inside the placing bag 2, an aluminum foil film 6 is fixedly connected to a surface of the placing bag 2, a paper board 7 is fixedly connected to a lower surface of the aluminum foil film 6, a plurality of triangular holes 8 are formed in a front surface of the paper board 7, a resin coating 9 is formed on an inner wall of the triangular holes 8, a water inlet pipe 4 is fixedly connected to a right side of the bag body 1, a left end of the water inlet pipe 4 penetrates through a right side of the aluminum foil film 6 and is communicated with the water storage tank 3, the placing bag 2 is used for placing food, the water storage tank 3 is used for placing hot water to preserve heat of food, the aluminum foil film 6 is used for reflecting heat radiation for secondary preservation, heat dissipation is prevented by the paper board 7 and the resin coating 9, such that the current polyethylene food bag does not have a heat preservation function, the health of human body is affected by eating cold food outside.

Wherein, the upper surface of the placing bag 2 is fixedly connected with a bag collar 10, the bag collar 10 is made of soft plastics, and the bag collar 10 made of soft plastics is convenient for sealing; the bag collar 10 is characterized in that four fixing blocks 13 are fixedly connected to the side faces of the bag collar 10, the four fixing blocks 13 are divided into two groups, a lifting handle 14 is fixedly connected to the upper surface of each group of fixing blocks 13, and the bag collar is convenient to carry by arranging the lifting handle 14; bag collar 10's left side inner wall fixedly connected with seal groove 11, bag collar 10's right side inner wall fixedly connected with seal bulge 12, seal groove 11 and seal bulge 12 looks adaptation are used for sealed placing bag 2 through setting up seal bulge 12 and seal groove 11, prevent to get into dust and bacterium in placing bag 2, lead to food rotten.

Wherein, the left side of the bag body 1 is fixedly connected with a tissue bag 16, tissues are arranged on the inner wall of the tissue bag 16, and the tissue bag 16 is arranged to store the tissues, so that the use after a meal is facilitated; the right side of the bag body 1 is fixedly connected with a garbage bag 15, the inner wall of the garbage bag 15 is provided with a deodorant, and the garbage bag 15 is used for placing garbage after meals, so that the environment is protected; the plug 5 is inserted into the inner wall of the water inlet pipe 4, the plug 5 is made of rubber materials, and the plug 5 is used for plugging the water inlet pipe 4 to prevent water in the water storage tank 3 from leaking.

Wherein, set up on the aqua storage tank 3 and have a plurality of groups elasticity water bag 22, elasticity water bag 22 and aqua storage tank 3 intercommunication, through setting up elasticity water bag 22, when the aqua storage tank 3 pours into hot water into, the communicating elasticity water bag 22 inflation of aqua storage tank 3 is bloated, and elasticity water bag 22 presss from both sides food, and the inside hot water heat transfer of elasticity water bag 22 is for food to realize fixed food and heat retaining effect.

Wherein, set up between aqua storage tank 3 and the second aqua storage tank 18 and communicate through trachea 23, trachea 23 entrance is located the upper left side, and the exit is located the right side below and exit and air outlet valve 21 intercommunication are connected, trachea 23 is connected in first placing bag 2 hugs closely inner wall department and encircles, can pour into the second aqua storage tank 18 into through second inlet tube 19 when the user cooks a meal in the open air, then heat the plastic bag bottom, and this kind of method has both solved the hot water condition that does not have outside, can realize the heat retaining effect of heating again.

The working principle of the invention is as follows: when going out, the user at first pours drinking hot water into aqua storage tank 3 from inlet tube 4, cover stopper 5 and preheat placing bag 2, then put into placing bag 2 the food that needs to take out after, fill in sealed arch 12 in seal groove 11 and seal and prevent that dust and bacterium contact food from making food rotten, reducible heat scatters and disappears simultaneously, carry handle 14 and go out the door, before edible, the hot water in the aqua storage tank 3 keeps warm for food constantly, aluminium foil membrane 6 constantly reflects the heat radiation and carries out the secondary and keep warm, waste heat is preserved to cardboard 7 and resin coating 9, reduce the speed that the heat scatters and disappears, thereby solved present polyethylene food bag and did not possess the heat preservation function, eat cold food outside, influence the problem of human health.

The other working principle of the invention is as follows: the user puts food in the inner chamber of first placing bag 2 before the field cooking earlier, then pours hot water into first aqua storage tank 3 from first inlet tube 4, cover stopper 5 and preheat, the hot water of drinking in the first aqua storage tank 3 can play the effect of heat transfer, and the elasticity water bag 22 that is connected with first aqua storage tank 3 this moment can be bloated after the injected water, elasticity water bag 22 can press from both sides tight food, play the effect of fixed food like this, improved the heat insulating ability to food again, need take the drinking water when the user field cooking, directly open the inlet tube and pour out hot water of drinking, the invention can both place food and place the drinking water.

When people want to heat food and heat-preservation food through a food bag, the second plug 20 can be opened and then natural water is injected, when the natural water enters the second water storage tank 18, a user can heat the bottom of the plastic bag through fire, the water inside the second water storage tank 18 is heated to be changed into steam, the steam is transmitted into the inner cavity of the first placing bag 2 through the air pipe 23, the air pipe 23 is of a surrounding structure at the inner wall of the first placing bag 2, the structure can achieve the heating and heat-preservation effects on the food, finally the steam is discharged through the air outlet valve 21, the air outlet valve 21 is arranged to prevent the steam from expanding due to overlarge air pressure when the steam is generated inside, the natural water is heated through being put in, then the bag body is heated through the air pipe, and the user can inject the natural water into the second water storage tank 18 through the second water inlet pipe 19 when people take a picnic, then the bottom of the plastic bag is heated, and the method not only solves the problem that no hot water exists outside, but also can realize the heating and heat preservation effects.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
