The specific embodiment

Below in conjunction with drawings and Examples, the technical solution of the utility model is further elaborated.

Embodiment 1

Referring to accompanying drawing 1, it is the structural representation of the vehicle-mounted food heater that provides of the present embodiment, and it is heating element heater that vehicle-mounted food heater adopts ptc material.Vehicle power plug 3 three parts that vehicle-mounted food heater comprises bag 1, is connected to the power line 2 on bag and can inserts vehicle power interface; Bag is provided with opening, and the locking devices such as zip 4 or button are set on opening; Bag is also provided with switch fixed switch panel 5, is fixed with total control switch 6, middle temperature control switch 7 and high-temperature control switch 8 on switch panel.

Referring to accompanying drawing 2, it is the part-structure schematic diagram of the vehicle-mounted food heater bag that provides of the present embodiment, and bag is three-decker, comprises outer decorative layer 9, thermal insulation separation thermosphere 10 and the interior fixed bed 12 that is embedded with PTC heating source 11; Shown in accompanying drawing 3, the heating source of PTC described in bag 11 comprises PTC temperature-sensitive element 13, heat conduction protective layer 14 and goes between 15, and the lead-in wire of all PTC heating sources is all by being connected in parallel on the power line 2 of bag; The rated voltage of PTC temperature-sensitive element all adopts vehicle carried power voltage, i.e. 12V or 24V, and so directly vehicle power heats.

Referring to accompanying drawing 4, it is the circuit diagram of the vehicle-mounted food heater that provides of the present embodiment, PTC heating source comprises three heating units, by total control switch 6, middle

temperature control switch

7 and 8 three gauge taps of high-temperature control switch, link together, PTC temperature-sensitive element 13 in each heating unit adopts parallel form to connect, each heating unit, according to several PTC temperature-sensitive elements 13 need to be set, reaches the heating-up temperature of controlling the vehicle-mounted PTC alimentary system of the utility model.When only closing total control switch 6, heating-up temperature is lower; When closing total control switch 6 and middle temperature control switch 7, heating-up temperature is middle temperature; When three gauge taps are all closed, heating-up temperature is the highest.
