CN201379454Y - Prompt thermos flask - Google Patents

Abstract

The utility model relates to a prompt thermos flask, which comprises a shell, an inner container, a lid and a handle, wherein two vertical supporting rods are disposed at the position close to the bottom in the shell, and the two supporting rods are respectively provided with a metal contact piece, a strong spring is arranged under the long-segment metal contact piece, and the inner container is arranged on the upper surface of the long-segment metal contact piece; the metal contact pieces are connected with a cell and a lamp bulb in series via conductors to form a lighting circuit, and the lamp bulb is arranged on the surface of the shell; and the inner wall of the shell is provided with a plurality of transverse limit stops. When having not water, the inner container is light, the strong spring can drive the metal contact pieces and the inner container to upspring to separate the two metal contact pieces, and the lighting circuit is disconnected at this time; and when water is poured into the inner container, the weight of the inner container is increased, the spring is pressed to move downwards, the lower metal contact piece is pressed by the inner container to attach to the other contact piece once the water quantity is excessive, the lighting circuit is turned on at this time, and the lamp bulb shines for lighting to remind users of excessive water pouring quantity. The utility model has the advantages of beautiful appearance, reasonable technology, safe use, convenience, good practicability and the like.

Description

Can point out thermos flask

Technical field

The utility model relates to a kind of daily necessities, especially a kind of thermos flask of pointing out.

Background technology

As everyone knows, thermos flask is a most important water instrument in people's life and work.But present thermos flask function ratio is more single, can only deposit, be incubated hot water, but can't provide suggesting effect when pouring, and result's hot water when being everlasting water filling is gushed out, and causes the scald accident.For this reason, we provide a kind of new-type thermos flask that possesses the water filling prompt facility very necessary.

Summary of the invention

The purpose of this utility model provides a kind of thermos flask of pointing out, and is used to solve common thermos flask lacks water yield prompting when water filling problem.

For achieving the above object, the utility model can be pointed out thermos flask, comprises shell, inner bag, pot lid and handle, near two vertical support bars of place, bottom processing, on two support bars the metal contact is installed respectively in the enclosure, and two metal contacts have the contact site; Brute spring is installed in long therein section metal contact below, and this metal contact upper surface is placed inner bag; The metal contact is composed in series lighting circuit by lead and battery, bulb, and bulb is arranged on case surface; Wall is installed many cross spacing retainings in the enclosure, and the cross spacing retaining closely contacts with inner bag.

After adopting said structure, when anhydrous, the lighter weight of inner bag, brute spring can drive the metal contact and inner bag is upspring, and makes two metal contacts break away from, and this moment, lighting circuit disconnected, and bulb is not luminous; During pouring, increase with rate of water added, the weight of inner bag increases, pressuring spring moves down, in case hypervolia is then fitted by metal contact and another sheet metal contact of inner bag compressing below, lighting circuit conducting this moment, bulb is luminous to throw light on, and reminds user's pouring amount excessive, should in time stop pouring.

Compared with the prior art, the beneficial effects of the utility model are: profile fineness, technology are reasonable, safe in utilization, convenient and practical, and eye-catching warning function can be provided, and improve the pouring security, in order to avoid hydraulic overflow problem.
