Description

All-function thermo-bottle

The utility model relates to a kind of daily living article, particularly relates to a kind of global function vacuum flask.

Usually water intaking has dual mode from vacuum flask, and a kind of is to open bottle cap inclination bottle, and water directly flows out from bottleneck, and hand touches bottle stopper, easily pollutes bottleneck, and is unhygienic.Another kind is a vapour-pressure type, inserts a pipe to the bottle end from bottleneck, pressurizes in bottle during water intaking, and water extrudes from pipe, and this mode can be harmful to health the sucking-off of bottom precipitation thing, and the cost height.Chinese patent notification number 2079925 discloses a kind of automatic open-close type vacuum flask, this insulation bottleneck is provided with a butterfly mouth, inner cap becomes to be fixedly hinged by a pin edge relative with butterfly mouth mouth, inner cap can rotate around pin, and balance weight body and heat-insulating material are arranged in interior lid, uses this vacuum flask, but inner cap automatic shutter, but bottle neck opens wide, and dust and small worm easily enter, and heat insulating ability is poor.

It is a kind of by improving bottleneck and bottle cap that the purpose of this utility model is to provide, but the global function vacuum flask of bottle cap automatic open close during use.

The utility model is to realize like this, comprise shell, place the inner bag in the shell, and be arranged on ring-shaped rubber pad between inner-tube mouth and the shell, it is approximate tubaeform that the shell upper oral part is, shell can be made an integral body, also can partly be formed by connecting the form that is threaded as employing by bottom barrel shell and top shoulder shell two.Shell upper oral part one end is a delivery port, and the other end is connected with the enclosing cover that matches with it by hinge, and the enclosing cover periphery all turns edge downwards except that delivery port and hinged place, and it is tighter that enclosing cover and shell place suitable for reading is cooperated, and prevents that dust or small worm from entering in the enclosing cover.Be fixed with the hollow interior plug that has passage on its bottom and the sidewall and match in the enclosing cover, the motion stops that cooperates with bottom air vent is arranged therebetween, be generally glass or non-toxic plastic ball with inner-tube mouth.In plug bottom with arc surface for well, bead can be sealed bottom air vent when guaranteeing the vacuum flask setting.The dividing plate of band passage can be set at interior plug middle part, it is divided into lower chamber, but passage equilibration flask inner air and outer air pressure, and current are unobstructed during pouring.

The advantage of the utility model global function vacuum flask is simple in structure, needn't take off bottle stopper during pouring, and bottle tilts, and enclosing cover and Nei Sai open voluntarily, and bottle is erect and closed voluntarily again.Use very convenient, and sanitation and hygiene, good heat preservation performance.

Describe the utility model embodiment in detail below in conjunction with accompanying drawing

Fig. 1: the utility model structural representation

The enclosing cover 4 that the utility model comprises shell 1, inner bag 2, cooperate with shell 1 upper oral part and be connected by hinge 3, be fixed in the enclosing cover 4 and be provided with diaphragm plate 5 in the middle part of it, and sidewall, dividing plate and bottom all have the interior plug 7 of passage 6, be arranged in the glass marble 8 of plug 7, and be arranged on the rubber washer 9 between inner bag 2 oral areas and the shell 1.

Claims (3)

1, a kind of global function vacuum flask, comprise shell and inner bag, it is characterized in that the shell upper oral part is approximate tubaeform, the one end is a delivery port, corresponding end is connected with the enclosing cover that cooperates with the shell upper oral part by hinge, be fixed with in the enclosing cover on its bottom and the sidewall and have passage, and the hollow interior plug that matches with inner-tube mouth, interior plug bottom is provided with the motion stops that cooperates with passage.

2, global function vacuum flask as claimed in claim 1, plug is gone to the bottom and is that arc surface, middle part are provided with the dividing plate of band passage in it is characterized in that, interior plug cavity is divided into goes up lower chamber, and the motion stops that interior plug bottom is provided with is a bead
