Description

A kind of electric heating vessel river gage structure

Technical field

The utility model relates to a kind of vessel water scale structure, particularly relates to a kind of electric heating vessel river gage structure.

Background technology

In the prior art, the river gage and the fixed form between the container that are used to observe liquid level in the container on the electric heating vessel generally are to adopt forms such as sweat soldering, high-frequency welding or ultrasonic soldering, these welding manners not only need to realize by specific plant equipment, increased production cost, also be easy to generate weld defects inevitably, cause the junction of container and river gage to leak, in addition owing to adopt welding manner, make between river gage after the welding and the thermal capacitance device inseparablely, river gage can't be changed after damaging.

It is 02108504.8 patented claim that China Intellectual Property Office discloses application number, but this patented claim discloses a kind of river gage structure that need not adopt the stainless steel insulating pot that any utility appliance directly installs with regard to mechanical type, it comprises a kettle body, on kettle body sidewall, offer an elongated vertical water surface and observe the aperture, be provided with a straight rib that extends internally along the periphery of observing the aperture, by the rib inner edge place stiffened edge that bends inwards, this stiffened edge has an inner edge; One is arranged on the transparent water scale of observing on the aperture, its peripheral size is suitable for embedding on the rib of kettle body, on the inside surface of river gage, vertically stretch out an annular jointing edge, insert and observe in the aperture, periphery at jointing edge outwards convexes with a plurality of clasps separately, engages with kettle stiffened edge inner edge on one's body; One compresses the elasticity heat resisting gasket between the rib of the inside surface that is arranged on river gage and kettle body, the size in its periphery and interior week is corresponding with the jointing edge of the periphery of river gage with shape, and the annular jointing edge on interior week can be inlaid between the stiffened edge of the annular jointing edge of river gage and kettle body.This river gage structural manufacturing process complexity, and the sharp keen inner edge of its clasp and stiffened edge contacts, can produce cutting action each other in use, between river gage and the kettle body because the gap that wearing and tearing form is increased, thereby cause the junction of kettle body and river gage to leak, when between the inner edge of the clasp of river gage and stiffened edge during serious wear, also can cause river gage to come off on one's body from kettle.

The utility model content

The purpose of this utility model is to provide a kind of structure, technology simple, is connected reliable and secure electric heating vessel river gage structure between river gage and the container.

The purpose of this utility model is achieved by the following technical programs:

A kind of electric heating vessel river gage structure of the present utility model, it comprises the electric heating vessel that has watch window, is inlaid in transparent water scale and the O-ring seal between river gage and watch window on the watch window, it is characterized in that the periphery of the described watch window sealing strip that extends internally out; Has an annular groove on the periphery of described transparent water scale, the longitudinal section height of described O-ring seal is higher than the height of annular groove, and lock ring is in this annular groove, the sealing strip of watch window is pressed on the O-ring seal, cause O-ring seal distortion under extruding, being extruded part does not push to being extruded part, make not to be extruded partly to be higher than and be extruded part, being squeezed high O-ring seal partly is pressed on the sealing strip outer rim of watch window, can make the river gage sealing and fixing on watch window, can avoid again because river gage directly directly contacts with the outer rim of sealing strip and friction mutually, the drawback that cutting brings.

Described sealing strip is the horizontal seal limit, and inwardly each virtual extended line is parallel to each other for it.

For sealing strip more closely is pressed together on the O-ring seal, described sealing strip, its inwardly each virtual extended line locate on one point to intersect.

The contact size and the river gage annular groove size of part of described O-ring seal and river gage annular groove is consistent.

Described O-ring seal, its cross sectional shape are rectangle.

Described O-ring seal, its cross sectional shape are "  " shape, so that river gage is more tight with connecting of watch window.

Described cross sectional shape is the O-ring seal of "  " shape, its jut is an arc, can make river gage more sealing and fixing on watch window, can avoid mutual again better and rub, cut the drawback of bringing because river gage directly directly contact with the outer rim of sealing strip.

Advantage of the present utility model is: (1) is at the periphery of the watch window sealing strip that extends internally out, and on the periphery of transparent water scale, establish an annular groove, the longitudinal section height of O-ring seal is higher than the height of annular groove, and lock ring is in this annular groove, the sealing strip of watch window is pressed on the O-ring seal, cause O-ring seal distortion under extruding, being extruded part does not push to being extruded part, make not to be extruded partly to be higher than and be extruded part, being squeezed high O-ring seal partly is pressed on the sealing strip outer rim of watch window, can make the river gage sealing and fixing on watch window, can avoid river gage directly directly to contact with the outer rim of sealing strip and friction mutually again, the drawback that cutting brings.(2) simple in structure, easy disassembling, good seal performance.
