The specific embodiment
Below in conjunction with accompanying drawing and preferred embodiment, the utility model is described in further detail.
As shown in Fig. 1-6, the utility model provides a kind of specific embodiment of lunch box, this lunch box comprises: lunch box main body 400 and cover of the lunch box 100, on described cover of the lunch box 100, be provided with steam overfolw hole 1011, on described cover of the lunch box 100, be also provided with and overflow port lid 102 for what hide described steam overfolw hole 1011; Described overflow port lid 102 comprise one be fixed on described cover of the lunch box 100 erection column 1022 and be arranged on described erection column 1022 one end and described overfolw hole 1011 be enclosed in to its inner elasticity umbrella shape block 1021.As shown in Figure 7, when pressing described umbrella shape while blocking a shot 1021 top, described umbrella shape 1021 reversal deformations of blocking a shot, like this, overflow port lid 102 in open mode described in just can making, overfolw hole 1011 be not subject to umbrella shape block 1021 covering and in open mode.
As Figure 3-Figure 4, be provided with an installing hole 101 on described cover of the lunch box 100, the other end of described erection column 1022 is provided with back-off 1024, and described back-off 1024 is limited to described erection column in described installing hole 101 with described umbrella shape block 1021.Utilize block 1021 and back-off 1024 that erection column is limited in installing hole 101, thereby pressing of convenient block make the reversal deformation of blocking a shot.
As shown in Figure 6, the upper port of described installing hole 101 is provided with a circle boss 1013 arranging along installing hole 101 orifice edge, and shown in Fig. 3, during the described overfolw hole of described umbrella shape block 1021 sealing, its inner side is adjacent at described boss 1013 places.Can utilize boss 1013 like this, make the sealing effect of umbrella shape block 1021 better.
The cross section structure triangular in shape of described boss 1013, in the upper port formation back taper enlarging of described installing hole 101.The back taper enlarging that this triangle boss 1013 forms, contributes to keep the block shape after distortion, meanwhile, enlarging outside, the contact-making surface of boss and umbrella shape block is larger, is more conducive to keep closed state.Certainly, this back taper enlarging also not necessarily will realize by boss is set, and also can extend out setting to installing hole 101 sidewalls.When pressing umbrella shape block, umbrella shape block reversal deformation, erection column declines, and back taper enlarging can be held the block of part distortion, thereby contributes to keep the deformation state of block.
As shown in Figure 6, described steam overfolw hole 1011 is arranged on described installing hole 101 around, and states steam overfolw hole 1011 and be arranged on described boss 1013, along described boss 1013, is distributed on described installing hole around.
At the present embodiment, described erection column 1022 is also for elastomeric material is made, and its external diameter is greater than the aperture of described installing hole 101.Be conducive to like this erection column 1022 in the interior fixed position of installing hole 101, when pressing, erection column moves down, and due to its elastic construction, makes it have elasticity, and then the state of holding position after pressing.
And as shown in Fig. 4-5, described erection column 1022 is hollow structure, has hole 1023, makes like this its strain easier.
In the present embodiment, the edge of described umbrella shape block 1021 is provided with convex edge 1025.By convex edge 1025, increase the contact area of umbrella shape block and cover of the lunch box, keep better sealing effect.
As shown in Figure 8, lunch box inside is also provided with: be arranged on inner bag 200 and the heater 300 of lunch box main body 400 inside, wherein said heater 300 comprises the heating plate 301 of the one deck of outer surface that is attached to described inner bag 200 for generating heat.
Heating plate 301 is arranged on the bottom surface of described inner bag 200, and its size, shape are corresponding with the bottom surface of described inner bag 200, from the bottom surface heating of inner bag 200, like this heating plate 301 arrange more conveniently, while heating effect is also better.Certainly, also heating plate can be attached at whole outer surfaces of inner bag 200, still, be difficult for like this processing, and bottom arranges heating plate the demand of heating can be reached.
On heating plate 301, be provided with and lock hole 302, the corresponding outer surface at described inner bag 200 is that bottom surface is provided with and described screw hole column corresponding to hole 302 202 that lock, described heating plate 301 by screw locking to the outer surface of described inner bag.Therefore because inner bag thickness is little, by screw hole column, screw 304 and lock hole 302 and lock heating plate 301 to inner bag 200 bottom surfaces, this kind of lock adhering arrangement is comparatively simple, also does not need to strengthen the thickness of inner bag.In addition, from lunch box main body 400 bottoms of lunch box capable of heating, be also provided with corresponding with described screw hole column 202 hole 402 that locks, described inner bag 200, heating plate 301 and described lunch box main body 400 lock together by screw 304 simultaneously, a plurality of parts can be realized and being locked simultaneously by one group of screw like this, structure is relatively simple, and processing and assembling are more for convenience.
In the present embodiment, described heater 300 also comprises a control circuit (not shown) heating for controlling described heating plate 301, control circuit is used for realizing Based Intelligent Control heating, while making to heat food, can guarantee heating problems and heat time.Control circuit is arranged on a side bottom of described inner bag 200, and described inner bag 200 is provided with one for dodging the fossaperturate 201 of described control circuit, makes like this lunch box inner space enough, guarantees that the overall structure of lunch box can not increase.
Meanwhile, the lunch box in the present embodiment is also provided with for pointing out lunch box to use the indicator lamp 405 of state.And described inner bag 200 bottom one sides are provided with a fixed mount 205 for fixing described indication 405 lamps and circuit board thereof corresponding to the position of described indicator lamp 405, described lunch box main body 400 is provided with for exposing the perforate of described indicator lamp 405 corresponding to the position of described fixed mount 205.
In the present embodiment, described heating plate 301 is the METAL HEATING PROCESS sheet that heat transfer efficiency is high, and this heating plate can adopt panel beating to realize.Described inner bag 200 can be plastic cement or stainless steel.
Above content is in conjunction with concrete preferred embodiment further detailed description of the utility model, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
