Description

Automatic cover-opening thermos bottle

The utility model belongs to a kind of daily living article.

At present, ordinary thermos bottle needs when pouring through pulling out lid, pouring, close action such as lid, the service routine complexity, and bottle cap can often eject in addition.

The purpose of this utility model is to provide a kind of automatic lid closing/opening vacuum flask easy to use, simple in structure.

The purpose of this utility model is finished in the following way:

Vacuum flask is made of shell (1), handle (2), bottle stopper (8) and inner bag, wherein, be fixed with support (6) in shell (1) upper end, lever (5) is fixed on support (6) top by jointed shaft (7), has spring on the jointed shaft, and lever (5) one ends are the annulus of band coarse-pitch thread, bottle stopper (8) is enclosed within the annulus, the other end of lever (5) connects a pull bar (4), and pull bar (4) other end connects switch (3), and switch (3) is hinged on the upper end of handle (2).

During use, catch handle, press switch (3), pull bar (4) is left behind lever (5) one ends, and the bottle stopper of its other end (8) lifts, automatically pouring.

The utility model compared with prior art, pouring action is simple and convenient, but the bottle stopper self-return can not eject good heat preservation performance.

The utility model is described in further detail below in conjunction with drawings and Examples:

Fig. 1 is the utility model front view, also is an embodiment

Fig. 2 is the another kind of structure of the utility model lever

Fig. 3 is the another kind of structure of switch

In Fig. 1: (1) shell; (2) handle; (3) switch; (4) pull bar; (5) lever; (6) support; (7) jointed shaft; (8) bottle stopper.

Embodiment 1: go up an also hinged guard shield at support (6), rise and fall synchronously with bottle cap, pull bar can adopt finer wire, and support can be made one with shell (1), is plastic material, and switch is a hookswitch, and stand spring is a torsion spring.

Embodiment 2: lever (5) is that two joints are hinged, and contact is in support jointed shaft upper end, and the contact place has spring catch, when irritating boiling water, bottle stopper solderless wrapped connection point is turned over more than 90 °, and all the other structures are identical with embodiment 1.

Embodiment 3: switch is a pusher-type switch, and all the other structures are identical with embodiment 1.
