Description

Insulating pot with hermetically-sealed construction of improvement

Technical field

The utility model relates to the structure of insulating pot, specifically is meant a kind of insulating pot with hermetically-sealed construction of improvement.。

Background technology

Insulating pot is one of requisite apparatus in people's daily life, is used for water is heated, and can be used as the container of water simultaneously again, has characteristics easy to use.Be provided with electric heater unit at the bottom of the kettle of insulating pot, early, this heater is an electrothermal tube, stretch in the container from container bottom is convex, so that the water in the container is heated,, get rusty because of being subjected to corroding easily owing to be exposed to fully in the water as the electrothermal tube of heat generating components, damage at last and can't use, and influence health.

Therefore, it is plane electric heater unit that designer has in the industry designed heating surface, and this electric kettle has two kinds of basic structures.A kind of is the canister that is formed in one of container of dress water, electric heater unit is located at its below, bottom, during heating, whole canister all can be heated, must outside canister, cover a plastic casing again, safe in utilization to guarantee, and between plastic casing and canister, thermal insulation layer must be arranged, thereby production technology bothers, cost is higher.Another kind is the bottom that electric heater unit is lifted on plastic containers, and its plane heating surface forms the bottom of heating container, directly contacts with water it is heated.

Hermetically-sealed construction between heater and the kettle body madial wall is the key factor of insulating pot performance.Existing hermetically-sealed construction is: the madial wall appropriate location at the kettle body is provided with a bulge loop, between heater periphery end face and this bulge loop bottom surface, establish a sealing ring, and on axially, a compressible spring assembly being set, this spring assembly applies one in the axial direction makes the sealing ring compression to reach the active force of sealing from bottom to top.Spring may occur and be compressed by water gravity in process to boil water, the situation of leaking does not tightly appear in sealing, and assembly difficulty is big, and cost is higher.

Another kind of hermetically-sealed construction is: sealing ring is between kettle body madial wall and heater outer peripheral face, the outer peripheral face of sealing ring generates the rib of two-layer bulge loop shape, during assembling, utilize this rib and kettle body madial wall inconsistent and produce the effect that flange in the same way reaches sealing, be provided with some ribs longitudinally at this kettle body madial wall, the sealing circle is between heater and each rib bottom face, and upwards hold out against by support ring self-heating apparatus below, make it fixing in the axial direction, and this support ring is sticked on the kettle body madial wall and reach the purpose of support fixation.This kind hermetically-sealed construction is prone to the rib flange direction that seals on the sealing ring and differs in assembling process, form waveform on circumference, cause leaking, and its assembly difficulty is also bigger.

Deficiency at above-mentioned two kinds of hermetically-sealed constructions, also designed another kind of hermetically-sealed construction in the industry: sealing ring is located in heater and is located between the step surface of kettle body madial wall, utilize a collar that is positioned kettle body inside to support the location axially: be provided with the grab of projection in the shirt rim part of kettle body bottom, collar snaps in each grab top from bottom to top and upwards holds out against heater.Because consideration assembly problem, so the pothook branch is designed to have certain elasticity, such structure have take place gravity effect that grab is subjected to its top heater and water to around open and cause cooperation to come off, for preventing this problem, on bottom, grow the whole shirt rim part that bulge loop is wrapped in the kettle body of enclosing, prevent that grab from opening outward, for reaching this purpose, this bulge loop and be subjected to the gap between the shirt rim part of its encirclement little.This has increased assembly difficulty again in assembling process, kettle body shirt rim is difficult for being inserted in the bulge loop of bottom, be this part-structure moulding on the kettle body simultaneously, mould structure will on have very dark groove, and mould can form a narrow and small angle of cut part, this aspect the moulding filling and die life the aspect all bad influence can be arranged.

The utility model content

The utility model adopts following technical scheme: the insulating pot with hermetically-sealed construction of improvement, the Hu Bi and the heater that comprise annular, this heater is located at the bottom position in the kettle wall, its end face and Hu Bi surround the space that is filled with water together jointly, the nearly bottom position of this kettle wall medial surface is provided with downward locating surface on one day, in the vertical direction is folded with a sealing ring between this locating surface and the heater top edge position, heater bottom edge position is provided with one with its insulating collar that upwards holds out against, kettle wall bottom is provided with the annular solid that is positioned kettle wall bottom periphery from the bottom to top by the snap fit fit, and the madial wall of this annular solid is provided with the protuberance that described insulating collar is upwards held out against.

Aforementioned insulating pot with hermetically-sealed construction of improvement, the bottom face of its insulating collar is lower than the bottom face of Hu Bi, and these characteristics are very easy to assembling.

Aforementioned insulating pot with hermetically-sealed construction of improvement, its annular solid bottom is provided with a bottom, and this bottom is by the sealed protuberance below of being fixed in this annular solid madial wall of screw.

Aforementioned insulating pot with hermetically-sealed construction of improvement, its kettle wall outer peripheral face is provided with some button holes, and the inboard of described annular solid is provided with somely can corresponding upwards slip into and fasten the barb-shaped fastener that is positioned in each button hole.

Aforementioned insulating pot with hermetically-sealed construction of improvement, its heater end face is provided with an annular protrusion near the peripheral part, the section of described sealing ring is L shaped, its lateral part is located between described locating surface and the heater top edge position, and its longitudinal component is between this annular protrusion periphery wall and kettle wall medial surface.

By above-mentioned description to the utility model structure as can be known, compare with prior art, the utlity model has following advantage: one, assembling is simple, realizes easily, during assembling, can earlier sealing ring be sheathed on the annular protrusion of heater, successively heater, insulating collar are inserted from the bottom to top the bottom of Hu Bi again, again with described annular solid from bottom to top fit be fixed in kettle wall lower, outer perimeter and get final product, assembling process is very simple; Two, sealing ring is being clamped on the whole circumference between described locating surface and the heater, and its sealing property is better, and is stable more and reliable; Three, make each parts obtain simplifying, thereby can reduce the complexity of mould, reduce production cost.
