Description
Technical field
The utility model relates to the structure of insulating pot, specifically is meant a kind of insulating pot of hermetically-sealed construction 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.
The utility model content
The utility model provides the insulating pot of a kind of hermetically-sealed construction improvement, and its main purpose is to overcome existing insulating pot because design of Sealing Structure is unreasonable, causes assembling inconvenience, easy shortcoming such as leak.
The utility model adopts following technical scheme: the insulating pot of hermetically-sealed construction 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 snap ring that upwards holds out against, the outer peripheral face of this snap ring is provided with some buckles, and kettle wall medial surface relevant position is provided with and respectively is clasped so that snap ring and the relatively-stationary draw-in groove of kettle wall.
The insulating pot of aforementioned hermetically-sealed construction improvement, its heater end face is in the inboard bulge loop that forms of sealing circle, and this bulge loop outer peripheral face and kettle wall medial surface are located in sealing ring therebetween in horizontal direction.
The insulating pot of aforementioned hermetically-sealed construction improvement, its snap ring has a fracture, and half that a buckle arranged in the some buckles on the described snap ring is formed at a side of this fracture, and second half forms the opposite side of this fracture.
The insulating pot of aforementioned hermetically-sealed construction improvement, the top margin of the cross section of its sealing ring and base are zigzag.
The insulating pot of aforementioned hermetically-sealed construction improvement, its kettle wall bottom outside is provided with a sheathing, this sheathing cutting ferrule is in kettle wall bottom outside, and this sheathing bottom is by the sealed base plate that is fixed with of screw, and this base plate is covered in its inside with sheathing with described heater.
The insulating pot of aforementioned hermetically-sealed construction improvement, its locating surface is made of a bottom surface that is formed at the bulge loop of shell wall medial surface.
The insulating pot of aforementioned hermetically-sealed construction improvement, its locating surface is made of a cascaded surface that is formed at the nearly bottom position of 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, the end face of sealing ring, bottom surface, lateral surface and medial surface are respectively and form sealing between the locating surface of kettle wall inboard, heater top edge position, kettle wall medial surface, heater end face bulge loop lateral surface, and, snap ring holds out against from bottom to top, the end face of sealing ring on whole circle Zhou Fangxiang fully and locating surface closely cooperate, can reach good sealing effectiveness, be better than the effect that in the past sealed greatly by the sealing ring flange; Two, the buckle by the snap ring lateral surface matches with the draw-in groove of kettle wall inboard and realizes that location, its structural stability are better than the effect that in the past held out against by spring assembly; Three, during assembling, elder generation on the bulge loop of heater, makes its lower surface be close to the marginal position of heater end face ring set, then heater is inserted by kettle wall bottom, until the locating surface that leans kettle wall medial surface, make the sealing ring upper surface be adjacent to locating surface, the buckle on the snap ring is snapped in the draw-in groove of Hu Bi, make its upper surface be adjacent to the marginal position of heater bottom surface, play the effect that upwards compresses, as seen, its assembling is very easy to realize; Four, its structure is extremely simple, is easy to realize on producing, and can not increase production cost.
