Description

Can once cover tight thermos bottle lid

Technical field

The utility model relates to a kind of thermos bottle accessory of the usefulness of drinking water, particularly relates to a kind ofly can once covering tight thermos bottle lid, and be to the improvement of existing thermos bottle lid structure of the same type, belong to daily living article.

Background technology

At present, the employed thermos bottle lid of people all is with metal or plastic production, profile is the cylinder of hollow, this kind pot lid is cheap, but also exist defective: when in thermos bottle, having irritated boiling water, need elder generation's kettle plug beyond the Great Wall, the pot lid of screwing on again, the action of promptly covering pot lid need be finished for twice, equally in thermos bottle outward during pouring, also need to take off respectively pot lid and kettle plug, not only the kettle plug also often takes place under the hot gas that expands promotes in trouble, by jack-up or eject suddenly and pot lid and N/R phenomenon, discover as untimely, the water in the thermos bottle is cooled off rapidly, lost insulation effect.In addition, because of pot lid and kettle plug are respectively two independently thermos bottle accessories, in the frequent pouring process of fetching water the phenomenon that one of them accessory is lost takes place very easily.

The utility model content

The purpose of this utility model is to overcome the prior art above shortcomings, and by improvement, provide and a kind ofly can once cover tight thermos bottle lid existing thermos bottle lid structure.This novel thermos bottle lid has reasonable idea, design is ingenious, the characteristics that cost of manufacture is low, can be once just that thermos bottle lid and thermos bottle gag is tight, saved twice cumbersome in the past action, not only avoid losing of pot lid and kettle plug, and might as well pick and place when fetching water in public places, kettle plug in the pot lid can not take place yet again simultaneously under the hot gas that expands promotes, by jack-up or eject suddenly and the phenomenon that causes the water in the kettle to cool off rapidly.

The technical scheme that the utility model provides is: this tight thermos bottle lid that can once cover includes a pot lid and kettle plug, is characterized in that the bottom in the described pot lid is provided with a compression spring, and the upper end of this compression spring is connected with the kettle plug.

Because pot lid and kettle plug are designed to integral type, just do not worry that one of them accessory loses.When covering pot lid, only pot lid need be tightened and get final product, and kettle plug nature under the spring applied pressure can be filled at the Hu Kou place, even it also is transient phenomenon that the excessive hot gas of air pressure in the kettle can back down the kettle plug, in case when internal and external pressure balance, particularly the pressure that forms when the hot gas in the kettle to the thrust of kettle plug less than spring during to the pressure of kettle plug, the kettle plug can be depressed and seal Hu Kou again, thereby reaches the purpose of insulation.Because the kettle plug located by spring, the phenomenon of skew can the kettle plug take place after by air-flow jack-up yet.

Compared with prior art, the beneficial effects of the utility model are: reasonable idea, the design ingenious, the characteristics that cost of manufacture is low, can be once just that thermos bottle lid and thermos bottle gag is tight, saved twice cumbersome in the past action, not only avoided losing of pot lid and kettle plug, and might as well pick and place when fetching water in public places, kettle plug in the pot lid can not take place simultaneously more yet under the hot gas that expands promotes, by jack-up or eject suddenly and the phenomenon that causes the water in the kettle to cool off rapidly.。

Description of drawings

Accompanying drawing is the structural representation of an embodiment providing of the utility model.

Number in the figure is: 1. pot lid, 2 springs, 3. kettle plug.

The specific embodiment

As shown in the figure, the utility model provides thisly can once cover tight thermos bottle lid, includes a pot lid 1 and kettle plug 3, and the bottom in the wherein described pot lid 1 is provided with a compression spring 2, and the upper end of this compression spring 2 is connected with kettle plug 3.

After in thermos bottle, pouring boiling water into, pressure in the kettle increases rapidly, because pot lid 1 and kettle plug 3 are integral type, when covering pot lid 1, only pot lid 1 need be tightened and get final product, and kettle plug 3 nature under spring 2 applied pressures can be filled at the Hu Kou place, even it also is transient phenomenon that the excessive hot gas of air pressure in the kettle can back down kettle plug 3, in case when the kettle internal and external pressure balance, particularly the pressure that forms when the hot gas in the kettle to the thrust of kettle plug 3 less than spring 2 during to the pressure of kettle plug 3, kettle plug 3 can be depressed and seal Hu Kou again, thereby reaches the purpose of insulation.Because kettle plug 3 located by spring 2, the phenomenon that skew takes place after by air-flow jack-up kettle plug 3 can not take place yet.
