Abstract

The utility model relates to a thermos flask kettle stopper is prevented inhaling in heat preservation, including the lower cock body and the upper end cover of connecting together and the seal cover on the lower cock body, cock body and upper end cover are equipped with central through-hole under to be equipped with the central through-hole lid that corresponds with central through-hole, be equipped with the internal thread at central through-hole inner wall, the central through-hole is covered there is the matched with external screw thread. The utility model is provided with the central through hole, when the kettle plug can not be pulled out, the central through hole cover is pulled out, the central through hole is communicated with the outside to achieve the air discharging effect, so that the kettle plug can be smoothly taken out, the operation is convenient, and the time and the labor are saved; when the heat insulation device is not used, the central through hole cover is screwed on the upper end cover, so that heat loss is avoided, and the heat insulation effect is better. The utility model discloses be equipped with the seal cover, prevent that steam from scattering and disappearing, make the kettle stopper leakproofness better, the heat preservation effect is advanced and is promoted.

Description

Thermos flask plug is prevented inhaling in heat preservation
Technical Field
The utility model relates to a thermos bottle equipment, concretely relates to heat preservation and heat absorption prevention thermos bottle plug.
Background
The thermos bottle is an indispensable daily necessity in daily life and is used for storing hot water. In the using process, firstly, the heat preservation effect of the thermos bottle is ensured; secondly, when the kettle is cooled by hot water in the kettle, the kettle plug can be adsorbed on the inner wall of the thermos bottle, and the kettle plug is pulled out at the moment, so that great effort is needed, time and labor are wasted, and accidents such as scalding and the like can also happen.
Disclosure of Invention
The defect and not enough to current kettle stopper, the utility model provides a thermos flask kettle stopper is prevented inhaling in heat preservation, its heat preservation effect obtains improving, and the kettle stopper is opened conveniently, avoids occurence of failure such as scald.
In order to achieve the above object, the present invention provides a technical solution for solving the technical problem: the utility model provides a thermos flask kettle stopper is prevented inhaling by heat preservation, comprises lower cock body and upper end cover, and both are as an organic whole structure, are equipped with the seal cover on the cock body down to be equipped with central through-hole and run through from top to bottom, be equipped with the through-hole lid at the upper end cover, the through-hole inner wall is equipped with the internal thread, and the through-hole lid is equipped with the external screw thread that corresponds with it.
The kettle plug is made of silica gel materials.
The utility model discloses be equipped with central through-hole, when the cock body can not be pulled out down, can rotate the through-hole lid and remove it from the upper end cover for central through-hole and outer looks switch-on reach the effect of unloading, so that pull down the cock body, convenient operation, labour saving and time saving avoids scalding the accident and takes place, screws the through-hole lid at the upper end cover not the time spent again, is used for plugging up central through-hole, avoids thermal scattering and disappearing, reaches better heat preservation effect. Meanwhile, a sealing sleeve is arranged to prevent the dissipation of hot air, so that the heat preservation effect is further improved.
Drawings
Fig. 1 is a schematic structural diagram of an embodiment of the present invention.
Fig. 2 is a schematic cross-sectional view of the central through hole of the present invention.
Description of reference numerals:
1. the plug comprises a lower plug body, 2 parts of an upper end cover, 3 parts of a central through hole, 4 parts of a central through hole cover, 5 parts of internal threads, 6 parts of external threads and 7 parts of a sealing sleeve.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
As shown in figure 1, the thermos bottle plug with the functions of heat preservation and heat absorption comprises a lower plug body 1 and an upper end cover 2 connected with the lower plug body, wherein a sealing sleeve 7 is arranged on the lower plug body, a central through hole 3 is formed in the lower plug body and the upper end cover, a central through hole cover 4 corresponding to the central through hole is arranged on the upper end cover, an internal thread 5 is arranged on the inner side wall of the central through hole, an external thread 6 corresponding to the internal thread is arranged on the central through hole cover, and the central through hole cover is assembled on the upper end cover 2 in a matched mode through the internal thread 5 and the external thread 6.
The kettle plug is made of silica gel, so that the manufacturing cost is low, the service life of the kettle plug is long, the cost and the materials are saved, and the resource waste is avoided.
