Description
Technical field
The utility model relates to a kind of improvement of heater, and be specifically related to a kind of safe and reliable slow cooker heating collar, this kind of heating collar is safe and reliable, and assembling is simple.
Background technology
Existing slow cooker heating collar many employings resistance wire is pyrotoxin, resistance wire is connected with the alloy flat filament resistance wire making lead-out wire, adopt copper strips terminal and heat-resisting copper core to be fixed together lead-out wire alloy flat filament again, outside put again high pressure resistant silicon sleeve pipe insulated after and circuit ON.Because this slow cooker heating collar wire is more, easily occur that single metal wire is exposed and punctures silicon sleeve pipe from copper strips terminal, leak electricity, cause the accident, the loaded down with trivial details efficiency of assembly process is low simultaneously, therefore it is necessary to carry out structure improvement for it.
Summary of the invention
The purpose of this utility model, is namely to overcome the deficiencies in the prior art, provides a kind of assembling simple, safe and reliable slow cooker heating collar.
The technical scheme realizing the utility model object is as described below:
A kind of safe and reliable slow cooker heating collar, described heating collar comprises heat-generating units, insulating unit and the wrapping unit for fixing parcel heat-generating units and insulating unit, wherein, described heat-generating units comprises middle mica sheet and is wound on the heating wire on this mica sheet, described insulating unit comprises the upper insulating concrete mica plate and lower insulating concrete mica plate that are separately positioned on described heat-generating units both sides, described wrapping unit comprises the galvanized sheet and outer alclad skin that are separately positioned on these insulating unit both sides, it is characterized in that: between described galvanized sheet and upper insulating concrete mica plate, be provided with porcelain bead, one end of this porcelain bead is through a hole be arranged on galvanized sheet, heat-resisting wire one end is through insulating concrete mica plate and this porcelain bead on this galvanized sheet and this, splice with the head end of the heating wire be wound on middle mica sheet or tail end, after the head end of this heat-resisting wire and heating wire or the part of splicing of tail end are each passed through the aperture that described middle mica sheet is arranged, bending is fixed on this middle mica sheet.
One end that described porcelain bead contacts with described upper insulating concrete mica plate has a boss; lug boss position on described galvanized sheet on relatively described porcelain bead has a storage tank; described boss is contained in wherein by this storage tank, plays and prevents porcelain bead from skidding off galvanized sheet and insulation protection and the effect of insulation distance between fixing galvanized sheet and upper insulating concrete mica plate.
Described porcelain bead adopts insulating ceramics pipe to make.
The slow cooker heating collar that the utility model provides, by heat-resisting wire directly and heating wire be wound around and connect, by and the blank area connect is fixed on mica sheet, deduct the middle transition line of metallic flat wires, after heating wire and heat-resisting wire are spliced, fix at not homonymy, guarantee joint is good, porcelain bead ensure that the safety creepage distance of heat-resisting wire and kalamein sheet simultaneously, and the lead-out wire of heat-resisting wire directly connects circuit, owing to reducing the connection of copper strips, decrease manufacturing procedure, deducted the use of insulating sleeve, structure is safer, and save time material-saving more.Not only ban welding heat-resisting wire and heating wire by the operation of both doublings, also improved both connection reliability simultaneously, thus improve the security of heating collar; Resistance to hot line and heating wire are wrapped on the core of resistance to hot line, guarantee that resistance wire and resistance to hot line have good contact, improve the pulling force of heat-resisting wire simultaneously, have stopped the high temperature fusing risk that heating wire and resistance to hot line cause because of loose contact; Heat-resisting wire penetrates the inner chamber of porcelain bead, and the projection section on porcelain bead is fixed by wrapping unit, and the copper core thoroughly having stopped heat-resisting wire exposes and the leaky caused.
