Abstract
A sealing structure of a water window of an electric kettle comprises a kettle body provided with a window, the water window arranged on the window and a water window cover thereof, wherein a water window fixing block is arranged between the water window and the water window cover, and the water window fixing block is tightly embedded in a groove of the water window; the sealing ring is arranged between the water window cover and the concave platform of the kettle body or between the water window and the concave platform of the kettle body; the water window fixing block and the water window are tightly fixed through secondary injection molding or high-frequency welding, and a plurality of positioning blocks are arranged between the water window and the water window fixing block to realize that the water window fixing block is completely separated from water. More than one annular flange is arranged on the bottom surface of the water window cover, triangular convex ribs are arranged on the annular flanges, and an annular groove is arranged on the water window fixing block and is fixedly matched and connected with the annular flanges. The water window fixing block and the water window are tightly embedded together and are completely separated from water, and the sealing ring is arranged between the water window cover and the concave platform of the kettle body. The novel sealing device is simple and reasonable in structure, fast to install, firm in connection, good in sealing performance, free of cracking and suitable for batch production.
Description
Technical field
The present invention relates to the hermetically-sealed construction of a kind of electric kettle, particularly a kind of water window of electric kettle.
Background technology
The hermetically-sealed construction of existing water window of electric kettle mainly with ultrasonic bonding, play screw or manner is fixed.Wherein the material require of ultrasonic bonding is transparent high temperature resistant material such as the PC material that is fit to ultrasonic bonding.But the hidden danger that hydrolysis is leaked in use can take place in the PC material.Chinese patent literature CN2692640 discloses a kind of electric heating vessel river gage structure on April 13rd, 2005, it comprises the electric heating vessel that has watch window, is inlaid in transparent water scale and the sealing ring between river gage and watch window on the watch window, the periphery that the it is characterized in that described watch window crimping that extended internally; Has an annular muscle position that adapts with the watch window shape on the inner surface of described transparent water scale, has the rib that a circle is outwards dug at the top of this muscle position, described annular muscle position and rib thereof insert in the watch window, between the crimping of the annular muscle position of transparent water scale and container watch window, be provided with a sealing ring, and the gap that the top of stretching in described rib and watch window crimping has an annular, embed in this gap by a fixture, the rib of end, transparent water scale annular muscle position is deducted on the top of crimping by fixture.If but the water window of this structure uses the PP material,, thereby can not guarantee the decrement of sealing ring and cause leaking because the PP material can dwindle behind pot water once more.If when using the PC material, after long-term the use, can produce the problem of hydrolysis cracking, thereby cause the water window position to leak.
Summary of the invention
Purpose of the present invention aims to provide the hermetically-sealed construction of a kind of handling ease, easy for installation, watertight water window of electric kettle, to overcome the deficiencies in the prior art part.
Press the hermetically-sealed construction of a kind of water window of electric kettle of this purpose design, comprise that the kettle body that is provided with window, water window and the water window thereof that is arranged on the window cover, its architectural feature is to be provided with water window fixed block between water window and water window lid, and water window fixed block is closely rabbeted in the groove of water window; Sealing ring is arranged between water window lid and the kettle body concave station, or is arranged between water window and the kettle body concave station; Described water window fixed block and water window are that quadric injection mould or high-frequency welding are closely fixing, are provided with several locating pieces between water window and the water window fixed block, keep apart fully to realize water window fixed block and water.
Described water window lid bottom surface is provided with one or more collar flange, and collar flange is provided with convex tendon triangular in shape.
Described water window fixed block is provided with annular groove, and annular recess and collar flange secure fit are joined.Water window fixed block and water window lid are made for being fit to ultrasonic bonding and resistant to elevated temperatures PC material, and water window and locating piece are transparent, and not hydrolysis cracking and resistant to elevated temperatures PP material are made.
Rounded, the square or flat in described sealing ring cross section; Can be arranged on the kettle body inboard or the outside.
Water window fixed block of the present invention and water window are closely rabbeted together, and separate fully with water, and sealing ring is arranged between water window lid and the kettle body concave station, or between water window and the kettle body concave station.It is simple and reasonable, quick for installation, be connected firmly, good seal performance, does not ftracture, and is fit to produce in enormous quantities.
