Abstract

The utility model relates to an automatic magnetized weight plug of a thermos. The purpose of the utility model is to provide a plug device which can be floated and placed on a bottle mouth of the thermos and can automatically open when the thermos is inclined. The automatic magnetized weight plug of the thermos can effectively overcomes the problems that pluging and pulling the plug is inconvent and unsanitary and the structure of a plug type automatic plug is complicated. The utility model just needs being provided with a root of metal weigth plug belw a plastic cap, so the structure is very simple. When the utility model is used, so long as inclining the thermos, the plug can automatically open. When the thermos is placed right, the plug can also automatically close. So the utility model is very convenient and sanitary, the automatic magnetized weighte plug of the thermos simultaneously has the functions of watering, magnetizing and descaling.

Description

Vacuum flask magnetization weight is filled in automatically

The utility model relates to a kind of magnetizing function and can be in sealing insulation when vacuum flask is upright under the weight effect of having, and when vacuum flask tilts the Weight type automatic vacuum flask bottle stopper device of unlatching automatically.

What the use at present of the bottle stopper of vacuum flask was maximum mainly is to rely on the plug cock body to enter bottleneck so that reach the mode of sealing insulation, as traditional cork and plastic plug.Because each pouring all will go to draw the cork with hand, so very inconvenient nor health on using.Though the automatic plug of recently existing plug type is employed the structure more complicated.

The purpose of this utility model provides a kind of floating by weight gravity and is placed on the vacuum flask bottleneck, the gag device that can open automatically when vacuum flask tilts can overcome the use inconvenience of plug bottle stopper and the complex structure problem of unhygienic problem and the automatic plug of plug type effectively.

The purpose of this utility model is achieved in that in the plastics gag bottom of a band drop handle sets up a metal bar with magnetic as weight.When vacuum flask was uprightly placed, gag on the vacuum flask bottleneck, played the sealing heat preservation effect at the gravity effect lower cover of weight.Also can make the hydromagneticization in the bottle this moment by the magnetic of weight, reaches the purpose of eliminating the part incrustation scale.And when pouring made vacuum flask tilt, gag can opened automatically under the weight effect and rely on a circle of gag bottom collude extension to the little protruding garden and the hook with the little garden of evagination on the bottleneck of convex equally, made that gag is unlikely to come off.If this device is used for duckbilled class vacuum flask, then the drop handle above the gag also can back down the vacuum flask top cover automatically, can turn over top cover earlier and get final product water outlet.

The utility model only needs to add a tup under vinyl cover, so structure is very simple.It will be opened automatically as long as vacuum flask is tilted, and vacuum flask is put just it can be closed again automatically, therefore very convenient and health.

The concrete structure of utility model is provided by following embodiment and accompanying drawing.

Fig. 1 is the erectility profile of filling in automatically according to the vacuum flask magnetization weight that the utility model proposes.

Fig. 2 is according to the profile of the automatic plug of vacuum flask magnetization weight under vacuum flask inclination opening that the utility model proposes.

Describe details and working condition in detail below in conjunction with Fig. 1, Fig. 2 according to the concrete device that the utility model proposes.

This device comprises the plastics gag (1) of a band drop handle, and the plastic bar bottom interlocking of its lower end or magnetic metal rod of plastic packaging are as weight (2), and the bottom of gag should have the little convex garden of a circle.

When vacuum flask was uprightly placed as shown in Figure 1, gag (1) is floating to be placed on the bottleneck, by the tight bottleneck of weight gravity pressure, plays the effect of sealing and insulation.

When vacuum flask tilted as shown in Figure 2, gag (1) then can be opened under the effect of weight, and this moment is owing to there being the hook that lay at the rear portion on the bottleneck (3) to collude extension with it, so any angle can not come off.The upper end of opposite hook with gag should be the little protruding garden of evagination.If gag is to use on duckbilled class vacuum flask, also can open top cover (4) in advance during pouring, the drop handle on the gag (1) will be automatically with its jack-up.

Claims

1. vacuum flask magnetization weight is filled in automatically, and the gravity that relies on tup makes the plastics gag seal insulation when vacuum flask is upright and automatic water outlet when tilting, and it is characterized in that: plastics gag (a 1) tup rod of central lower hanging (2) of being with drop handle.

2. according to the described automatic plug of claim 1, it is characterized in that the inside little dome of a circle is arranged at gag (1) bottom, can be hooked on the hook (3) of vacuum flask metastomium upper end evagination when vacuum flask inclination gag is opened.

3. according to the described automatic plug of claim 1, it is characterized in that tup rod (2) has magnetic.
