Abstract
A double-layer heat insulation kettle cover comprises a kettle cover, wherein a convex column extends from the lower part of the kettle cover, the convex column is of a hollow structure, and a certain distance is kept between the convex column and the upper part of the kettle cover to form a heat insulation cavity; the fabrication hole of the kettle cover is provided with a sealing element. The sealing element is a sealing plug which is sleeved on the technical hole; a groove is formed in the middle of the sealing plug, a first pressing shoulder and a second pressing shoulder are arranged at two ends of the groove respectively, and the diameter of the first pressing shoulder is smaller than that of the second pressing shoulder. The utility model adds the heat insulation cavity, and the air in the kettle cover is pumped out and then is sealed into a vacuum state, so that the temperature of the outer surface of the kettle cover can be effectively reduced when the kettle cover is heated, the problem that the surface temperature of the kettle cover exceeds the national safety standard for ceramic temperature rise is solved, and the heat dissipation in the kettle can be reduced, thereby achieving the purposes of heat preservation and energy saving; meanwhile, the sealing element plays a role in preventing water vapor from entering the heat insulation cavity of the kettle cover in the heating process; the structure is simple and reasonable, the cost is low, and the assembly is convenient and quick.
Description
Technical field
The utility model relates to a kind of double thermal insulation pot lid.
Background technology
At present, various hot-water bottles are arranged on the market, the appearance of electric kettle, heating up water to people brings great convenience, and heating up water with electric kettle mainly is that time of heating up water is short, and the mode of heating up water is simple and direct, and connecting with the mains gets final product.Especially the appearance of ceramic electric heating kettle, people use not only light but also safer.
A kind of ceramic electric heating kettle was disclosed on May 5th, 2010 as Chinese patent literature CN201445343U, comprise kettle body and chassis, pot lid is placed on kettle body top, on the kettle body, switch is arranged, kettle body bottom is arranged at the bottom of kettle body, and the described heat-generating disc that is installed in kettle body bottom is provided with temperature controller and heat-generating pipe, and it is characterized in that: the limit, outer of heat-generating disc is successively pressed with sealing ring and pressing plate, also have through hole on pressing plate and the sealing ring, the through hole that screw rod passes on kettle body bottom, sealing ring and the pressing plate is connected to nut again.It is said that it is spirally connected and makes the kettle body not have the seepage problem, guarantees safe in utilization bottom sealing ring and pressing plate and kettle body; Provide simultaneously a kind of novel, clean electric kettle easily.But the pot lid of this structure is an individual layer, because ceramic heat conduction is fast, in the process of heating up water, the temperature of pot lid outer surface is very high, surpasses the safety standard of country to ceramic temperature rise.May cause the danger of scald to the user, have very big potential safety hazard.Therefore, be necessary to be further improved and perfect.
The utility model content
The purpose of this utility model aims to provide a kind of simple and reasonable, safe and reliable and practical and attractive double thermal insulation pot lid, to overcome weak point of the prior art.
A kind of double thermal insulation pot lid by this purpose design comprises pot lid, and a projection is extended in the bottom of this pot lid, and its architectural feature is that described projection is hollow structure, and the top of projection and pot lid maintains a certain distance, and forms a heat insulation cavity; The fabrication hole of pot lid is provided with seal.
Described seal is a sealing-plug, and sealing-plug is sheathed on the fabrication hole; The middle part of sealing plug offers groove, and the two ends of this groove are respectively equipped with first and press the shoulder and the second pressure shoulder, and first presses the diameter of shoulder to press the diameter of takeing on less than second.
Described fabrication hole is arranged on the bottom or sidewall of pot lid, and groove on the sealing-plug and fabrication hole are that matched in clearance is fixed or interference fit is fixed; The shape of sealing-plug is " worker " font; The material of sealing-plug is silica gel product or plastic cement product.
The material of described pot lid is ceramic objects or boccaro product; The bottom of pot lid is provided with more than one shackle member.
Described shackle member is two, and it is around on the projection that is arranged at pot lid.
The utility model is by setting up heat insulation cavity, air in the pot lid is extracted out rear enclosed become vacuum state, can effectively reduce the temperature of pot lid outer surface when being heated, solved the pot lid surface temperature and surpassed the safety standard of country ceramic temperature rise, and can reduce the interior heat of kettle and scatter and disappear, to reach insulation and purpose of energy saving; Simultaneously, seal plays the interior effect of heat insulation cavity that prevents that water vapour enters pot lid in the heating process; It has structure have advantages of simple, with low cost, percent defective is low and characteristics efficiently easy to assembly.
