Abstract
The utility model provides a vacuum heat preservation lifting pot which comprises a pot body, an outer pot cover and a handle and further comprises an inner pot cover. A U-shaped protrusion is arranged inside the inner pot cover, a cavity is formed between the protrusion and a cover top of the inner pot cover, an air inlet button switch is arranged on the middle portion of the inner pot cover, the inner pot cover is made of plastic with poor heat-conducting property, the inner pot cover is in sealing connection with the pot body through threads, and the pot body and the outer pot cover are both of a dual-layer vacuum structure. The vacuum heat preservation lifting pot can guarantee thermal insulation property while solving the problem that the pot covers are difficult to open by the user due to different pressures inside and outside the pot. The vacuum heat preservation lifting pot is simple in structure and convenient to use.
Description
Technical field
The utility model relates to a kind of cool-bag, particularly a kind of vacuum heat insulation lifting pot.
Background technology
Present cool-bag on the market is a lot, but be mostly to adopt the single-layer metal material of good heat conductivity to make, its heat-insulating property is relatively poor, even if heat-insulating property is cool-bag preferably, the food that needs thermal protection is after the long period is placed by section within it, also having more heat transfer runs off, and the sealing property of general cool-bag is fine, in the process that the internal tank heat slowly runs off, owing to the reason of expanding with heat and contract with cold, cause the air pressure of internal tank to be lower than the atmospheric pressure of external container, this moment, difficulty relatively when opening the lid of container was brought very large inconvenience to the user.
The utility model content
In order to overcome the deficiencies in the prior art, the utility model provides a kind of vacuum heat insulation lifting pot, and when guaranteeing heat-insulating property, solved the user and opened and carry relatively hard problem of pot cover, and simple in structure, easy to use.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of vacuum heat insulation lifting pot, comprise a pot body, outer pot cover and handle, it is characterized in that: also comprise an inner pot cover, there is a U-shaped projection inner pot cover inside, form cavity between projection and the inner pot cover caping, the inner pot cover middle part arranges an air inlet press button, the relatively poor plastics of described inner pot cover employing heat conductivility are made and are tightly connected by screw thread and a pot body, when pressing the air inlet press button, carrying between pot inside and the external environment condition is the non-tight state, and inner pot cover is the same with outer pot cover can freely be dismantled.
Described air inlet press button comprises a larger upper flattened cylindrical body and a less lower flattened cylindrical body, connect by an elongate cylinder bar between two flattened cylindrical bodies, a spring is installed in the cylindrical bar outside, one end of spring pushes up the downside of flattened cylindrical body, the other end pushes up on the surface of described U-shaped projection, a rubber washer is installed to play sealing function between the outer surface of lower flattened cylindrical body and U-shaped projection.
Described pot body and outer pot cover are the double-layer vacuum structure, and pot body inside is provided with one or two degree of depth box different from the pot body.Described pot body, outer pot cover, handle and box are made by stainless steel material.
Described handle can be fixed on outer pot and cover, and also can be connected with the pot body by other means.
Good effect of the present utility model is: when guaranteeing to put forward pot good thermal insulation property, pot cover inside arranges a relatively poor inner pot cover of thermal conductivity with air inlet button outside, the user only need click the air inlet press button gently before opening inner pot cover, the outer air of pot is entered in the pot, this moment, the pot inner and outer air pressure equated, the user can open inner pot cover easily, and this utility model is simple in structure, and is convenient durable.
Description of drawings
Fig. 1 is the structural representation of a kind of Thermal insulating carrying pot of the utility model
Fig. 2 is the partial enlarged drawing of a-quadrant among Fig. 1
Among the figure: 1. pot body, 2. outer pot cover, 3. handle, 4. inner pot cover, 5. air inlet press button, 6. box, 7.U type projection, 8. cavity, 9. spring, 10. rubber washer.
The specific embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is elaborated.
With reference to Fig. 1, the utility model preferred embodiment a kind of vacuum heat insulation lifting pot is provided, comprise pot body 1, outer pot cover 2 and handle 3, also comprise an inner pot cover 4, inner pot cover 4 inside have one U-shaped protruding 7, U-shaped protruding 7 and the inner pot cover caping between form cavity 8, inner pot cover 4 middle parts arrange an air inlet press button 5, described air inlet press button 5 comprises a larger upper flattened cylindrical body and a less lower flattened cylindrical body, connect by an elongate cylinder bar between two flattened cylindrical bodies, cylindrical bar outside mounting spring 9, one end of spring 9 pushes up the downside of flattened cylindrical body, the other end pushes up on described U-shaped protruding 7 the surface, a rubber washer 10 is installed to play sealing function between lower flattened cylindrical body and U-shaped protruding 7 outer surface.The relatively poor plastics of inner pot cover 4 employing heat conductivilitys are made and are tightly connected by screw thread and a pot body 1.
Described pot body 1 and outer pot cover 2 are the double-layer vacuum structure, and described pot body 1, outer pot cover 2 and handle 3 and box 6 are made by stainless steel material, and pot body 1 is provided with the different box 6 of a degree of depth and pot body 1.
Described handle 3 is fixed on the outer pot cover 2.
During use, at first outer pot cover 2 and inner pot cover 4 are backed out from pot body 1, the food that needs thermal protection is placed in pot body 1 and the box 6, this is two-layer can place different food, then inner pot cover 4 is tightened on pot body 1, simultaneously because the effect of air inlet press button 5 upper springs 9 and rubber washer 10 so that inner pot cover 4 is tightly connected with pot body 1, is tightened in pot body 1 with outer pot cover 2 at last.The vacuum environment of pot body 1 and outer pot cover 2 effectively intercept heat is from inside to outside conducted, and the setting of inner pot cover 4 also blocked the loss of heat to a certain extent so that in the pot food can be efficient, be incubated lastingly; Before food is taken out in pot, at first outer pot cover 2 is backed out from pot body 1, then press air inlet switch button 5, present non-tight state between described vacuum heat insulation lifting pot inside and the external environment condition this moment, so that the air in the cavity 8 are entered in the pot, outside the pot internal gas pressure returns to pot, after the atmospheric pressure, back out at last inner pot cover 4, take out food in the pot.Pot body 1, outer pot cover 2 and handle 3 all adopt stainless steel material to make, and be not easy to wear, convenient for cleaning, and handle 3 is so that user side's Portable belt.
