Abstract

The invention discloses an electric heating lunch box, which consists of a lunch box cover and a lunch box body, wherein a heat conducting plate is placed at the bottom of the lunch box body, an electric heating element connected with the heat conducting plate is placed under the heat conducting plate, the electric heating element is at least one positive temperature coefficient (PTC) heater, the edge of the lunch box cover is inwards turned and is subject to die casting to be pressed into a sealing ring, and the bottom lateral side of the lunch box body is provided with a power supply socket in matched connection with the built-in electric heating element. An electric heating generator adopts the PTC heater, the automatic constant temperature maintaining is realized, the electricity is saved, the safety performance is high, the sealing ring is arranged at the inner side on the lunch box cover, a better heat insulation effect can be realized when the lunch box is not heated, and a power supply socket cover is covered on the power supply socket, so the functions of preventing water entering a plug during the cleaning and preventing dust and impurities from invading the lunch box are realized.

Description

Electric heating mess tin
Technical field
The present invention relates to a kind of electric heating mess tin, belong to technical field of dinnerware.
Background technology
Electric heating mess tin is as tableware commonly used, by broad masses are welcome.At present, most of electric heating mess tins all are to be made up of lunch box body and cover of the lunch box, and in inside parts such as electrothermal generator are installed.These electric heating mess tins can carry out insulation effect, but there is certain defective in it: because lunch box seals, when carrying out electrical heating, the circulation of lunch box steam inside is poor, and heat time heating time is long; The electrothermal generator temperature is non-constant, and not power saving, security are not high; When not heating, poor sealing performance; It is inconvenient that supply socket does not have the cleaning of covering.
Summary of the invention
The present invention provides a kind of convenient electric heating mess tin that uses in order to overcome the deficiency of prior art.
The present invention can be achieved through taking following technical scheme:
A kind of electric heating mess tin; Be made up of cover of the lunch box and lunch box body, the bottom of said lunch box body is placed with heat-conducting plate, and the below of said heat-conducting plate is placed with the heating that is connected with heat-conducting plate; The top of said heat-conducting plate is placed with inner bag; Said cover of the lunch box is provided with exhaust hole, is coated with the steam discharge lid on the said exhaust hole, and said heating is an at least one ptc heater; The edge of said cover of the lunch box overturns and die casting indentation sealing circle to the inside, the supply socket that said lunch box body bottom avris setting and in-built electrical thermal element are connected.
On the basis of the above, steam discharge lid according to the invention is umbrella body shape, and its intermediolateral column body portion embeds in the groove of cover of the lunch box, and peripheral part covers on the exhaust hole; Said steam discharge lid is made up of the soft plastic material; Said sealing ring is made up of the soft plastic material; Said supply socket is outer to cover a power supply flap that can flexibly connect with the lunch box body.The big or small attacker that is symmetrically distributed respectively on the said cover of the lunch box avris, said big or small attacker and cover of the lunch box are fastened and connected.
The present invention does further improvement: a side is provided with handle on the said cover of the lunch box, is convenient for carrying lunch box.
The present invention does further improvement: said cover of the lunch box opposite side is provided with the soupspoon lid, and is convenient and healthy.
Compared with prior art; The present invention has the following advantages: electric heating mess tin of the present invention is through being provided with exhaust hole and steam discharge lid; Lunch box steam when carrying out electrical heating can be ejected from exhaust hole, thereby lunch box when heating steam inside can be circulated, shorten heat time heating time; Electrothermal generator adopts ptc heater, automatic constant-temperature, and power saving, safe; The inboard is provided with sealing ring on the cover of the lunch box, when not heating, can better be incubated; Cover supply socket in the supply socket function that latch is intake and prevented the intrusion of dust foreign material when preventing to clean is arranged.
