The upper edge of the shell is embedded into an annular upper rabbet of the upper end of the internal kettle body, and the lower edge of the shell is inserted into an annular lower rabbet formed between a lower cover and the internal kettle body. The electric heating kettle has the advantages of simple structure, easy assemblage, high safety and high thermal efficiency.

Description

A kind of electric kettle

Technical field

The utility model relates to electric heater unit, belongs to a kind of electric kettle.

Background technology

The electrical heating kettle uses very extensive, its formation mainly includes elements such as kettle body, pot lid, base, handle, heating temperature control, its kettle body generally is made of metal level or plastic layer respectively, the kettle body that is made of metal level has very high surface temperature owing to it, the user is scalded, and because of its metal level rapid heat dissipation, the waste electric energy.Only the kettle body that is made of plastic layer also is weak because of the deficiency that the strength of materials, aspect such as ornamental are arranged.For overcoming deficiency and shortcoming, described by the disclosed patented technology of ZL02289992.8 mainly is that the kettle body of insulating pot is according to interior and be made up of metal level, heat insulation layer and plastic layer outward.This technology should have efficiency of heating surface height, security performance good, saved advantages such as energy, but its structure fabrication, aspect such as safe and reliable, but still have improvements.And by the said electric kettle of ZL00201321.5, though the gap of heat-blocking action has been arranged between kettle body case and inner bag, manufacturing process is complicated, the part of also making troubles.

Summary of the invention

The purpose of this utility model is to overcome the deficiency of prior art, proposes a kind of safe in utilization, advantages of simplicity and high efficiency electric kettle.

Technical measures of the present utility model are: interior kettle body, shell that the kettle body is made up of plastic layer, metal level from-inner-to-outer, and push down with handle at the position that the shell bag holds together; In the shell upper edge embeds on the annular of kettle body upper end in the seam, the shell lower edge insert form between lower cover and the interior kettle body annular under in the seam.

Technical measures of the present utility model in addition also include: the belt groove that can match with the bottom sediment of kettle body bottom lower cover is arranged on base; Pot lid is by spring, slide fastener and the automatic open torsion spring of pot lid is formed; It is in the switch bracket of box-like structure that steam cock is contained in.

The utility model is compared with prior art, and its beneficial effect has: 1, this electric kettle is on the basis of plastics kettle body, and shell is the material with metal-like, as the plastic housing of stainless steel or aluminium skin, spray metallic paint etc.Make integral body have the outward appearance of metal kettle, and interior kettle body still is filled with water, heat up water with the plastics with food-grade; 2, owing to add and used material with metal-like, not only have ornamentally, and make the kettle body become double-decker, form shell and interior kettle body.Because gapped between shell and the interior kettle body,, and also has insulation effect so the boiled rear casing of water can not scald one's hand; 3, the annular recess on the base matches with bottom sediment below the lower cover, not only promotes the positioning action of kettle body and base, and make the kettle body heat up water, shockproof when rotating, stable.4, the position held together of metal level bag does not add any fixture, radially is in free state with interior kettle body, and in the time of preventing effectively that water temperature from changing, the shrinkage of expanding of interior kettle body heat causes casing deformation, deviates from, defectives such as folding line, dislocation.Directly push down with handle, simple in structure, assembling easily.5, pot lid adopts slide fastener to cooperate the compression spring, and simple in structure, easy to use, the torsion spring of pot lid back can also make it open automatically.6, switch bracket adopts box-like structure, and steam cock is contained in the switch bracket, not only assemble simple and easy, put in place easily, and, the interference of various factors to steam cock can be reduced to a minimum, such as dabble, be out of shape, vibrations etc., thereby effectively prevent the wrong generation of phenomenon such as jumping, not jumping of switch.

The specific embodiment

Now in conjunction with the accompanying drawings the utility model is described further, as shown in Figure 1, the structure of this electric kettle has: 1 spring, 2 slide fasteners, 3 screen packs, 4 gauges, 5 interior kettle bodies, 6 shells, 7 lower covers, 8 bottom sediments, 9 power lines, 10 power supply lower connectors, connector on 11 power supplys, 12 grooves, 13 heat-generating discs, 14 switches pull out button, 15 steam cocks, 16 switch brackets, 17 torsion springs, 18 pot lids, 19 kettle bodies, 20 bases, 21 handles, 22 heating temperature control element, seam on 23,24 times seams.

Interior kettle body 5, shell 6 that kettle body 19 of the present utility model is made up of plastic layer, metal level from-inner-to-outer.Shell 6 can be that stainless steel or other have the material of metal-like, as the plastic housing of aluminium skin, spray metallic paint etc.Interior kettle body 5 still constitutes with the plastics with food-grade.Make kettle body 19 become double-decker like this, holding together between the interior kettle body 5 of plastic layer to be free state radially by stainless steel casing 6 bag, make between shell 6 and the interior kettle body 5 gapped, push down with the handle 21 that upper and lower side axially links to each other at the position that stainless shell (6) bag holds together, and fix with screw at four jiaos.In shell 6 upper edges embed on the annular of kettle body 5 upper ends in the seam 23, shell 6 lower edges insert formation between lower cover 7 and the interior kettle body 5 annular under in the seam 24.Such electric kettle not only can not scald one's hand, and is safe in utilization, and simple in structure, assembling easily and has insulation effect, energy efficient.In addition, the annular recess 12 that can match with the bottom sediment 8 of kettle body 19 bottom lower covers 7 is arranged on the base 20.Pot lid 18 is by spring 1, slide fastener 2 and pot lid 18 automatic open torsion springs 17 are formed.In addition, steam cock 15 is contained in the switch bracket 16, and switch bracket 16 is box-like structures.So in use, can stir slide fastener 2, pot lid 18 can be opened automatically, just can inject cold water, also can not open pot lid 18 certainly directly in the water filling of Hu Kou place.After treating water filling according to quantity, build pot lid 18, kettle is placed on the base 20, toggle switch pulls out button 14 to " 1 " position, can heat and heat up water, and water is opened back steam cock 15 automatic trippings, and switch pulls out button 14 and goes back to " 0 " position automatically, can stop heating.
