Abstract

The utility model provides an automatic water supply device for a thermos bottle. The various existing thermos bottles are difficult for water fetching, but the utility model realizes automation for the water fetching of the thermos bottle. The utility model is characterized in that a glass liner (13) is inversely installed, and an opening of the glass liner is sealed by rubber sheets (10); a water inlet pipe (17), a ventilating pipe (12) and an inner water outlet pipe (11) are all inserted with the rubber sheets (10); the inner water outlet pipe (11), a rubber pipe (6) and an outer water outlet pipe (7) are communicated with each other orderly; two spring clips (8) via two small round rods (5) clamp the rubber pipe (6); the middle point of one small round rod (5) is communicated with a power point of a lever (2). When the gravity of a cup (4) via a tray (3) acts on the middle point of the lever (2), the spring clips are pulled apart, and the water flows out; when the cup (4) is taken away, the water stops flowing. The water outlet can also be controlled through operating the lever (2) by manpower.

Description

The vacuum flask automatic water supply device

The utility model relates to a kind of liquid of supplying automatically from container, particularly from the device of vacuum flask automatic water-supply.

At present from ordinary thermos bottle water intaking, through: remove to cover, draw the cork, carry bottle.Step such as pour into, transfer, adorn plug, add a cover is quite loaded down with trivial details and hard; Test the vacuum flask water intaking of calming the anger, also will press secondary at least, just can get one glass of water with 0.92 kilogram pressure.Cup is 60m.mx100m.m.Electric thermos bottle has the electric shock possibility, and palpus transformer etc. are subjected to power limitations; Too expensive again with direct current.

The purpose of this utility model is the water fetching device that a kind of vacuum flask will be provided, and it can be when vacuum flask is fetched water, and is both laborsaving, easy again, and must not add the external energy such as battery etc. in addition.

The utility model is achieved in that the glass liner upside-down mounting, seals with sheet rubber, an end of interior outlet pipe is inserted sheet rubber communicate with glass liner; Interior outlet pipe, rubber tube, outer outlet pipe, connection successively.Through two little garden rods, make a concerted effort to clamp the rubber tube sealing with two spring clips.One garden rod mid point and lever force link; When the gravity of cup when pallet acts on the emphasis of lever, spring clip is drawn back, rubber tube just recovers passage by self elasticity, the water in the glass liner can flow out through rubber tube; Take cup away, spring clip loses pulling force, and is closed again, again rubber tube clamped sealing, and water promptly arrheas, thereby realizes that the ＂ cup comes water, and cup anhydrates and stops the purpose of ＂; Certainly also available manpower direct manipulation lever, the control water outlet.Because of the glass liner upside-down mounting, so must on sheet rubber, insert a water inlet pipe, so that intake to glass liner; During for the elimination water-in and water-out, produce positive and negative pressure in the glass liner, must on sheet rubber, insert a breather pipe again, to eliminate positive and negative pressure.

The starting point of the present utility model is not placed on and how extracts drinking-water in vacuum flask, does the acting again of unavoidably will requiring great effort like this; But, make the starting point move on to the sealing of assurance vacuum flask and do not leak by with the glass liner upside-down mounting; Only when needs are fetched water,, abandon sealing in specific part, the water in the glass liner, promptly reliably the potential energy of self has spilt voluntarily; Thereby make the water intaking operation of vacuum flask, become simple and laborsaving.

Fill with 100 ℃ of boiling water simultaneously to the utility model vacuum flask, the vacuum flask of calming the anger, ordinary thermos bottle; After 24 hours, measure three vacuum flask water temperatures simultaneously; 65 ℃ of the vacuum flask water temperatures of calming the anger, 68 ℃ of ordinary thermos bottle water temperatures, 71 ℃ of the utility model vacuum flask water temperatures.Test shows: water inlet pipe, interior outlet pipe, breather pipe insert glass liner by the bottom, and tangible heat insulation effect is arranged; So make the utility model vacuum flask water inlet, allow and cover uncork; Both saved stopper, indirect pollution drinking-water also further simplifies the operation after can avoiding hand again and shelving the environmental pollution stopper.

Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.

Accompanying drawing is profile and the relevant view according to the vacuum flask automatic water supply device that the utility model proposes; Below in conjunction with accompanying drawing, describe detailed rules and regulations and working condition in detail according to the concrete device that the utility model proposes.Fig. 1 is a vertical view of the present utility model; Fig. 2 is the profile of this device.

This device comprises: (one) outlet system; (2) control system; (3) complementary part in addition.

(1) outlet system: by interior outlet pipe [11], outer outlet pipe [7] is formed with the rubber tube that is connected them [6].Sheet rubber [10] is inserted in the upper end of interior outlet pipe [11], communicates with glass liner [13].

(2) control system: two spring clips [8], two little garden rods [5], iron wire [1], lever [2], pallet [3] is formed.Two spring clips [8] are fixed on the pressing plate [9], and through two little garden rods [5], make a concerted effort to clamp rubber tube [6] sealing.

When cup [4] was placed on the pallet [3], the gravity of cup [4] drew back spring clip [8] through lever [2], iron wire [1], little garden rod [5]; After rubber tube [6] is released, by self elasticity, recover passage, the water in the glass liner [13] just can pass through rubber tube [6] and flow into cup [4]; The cup [4] of taking away, spring clip [8] are clamped rubber tube [6] sealing once again, stop water outlet.Rubber tube [6], sheet rubber [10] must be the food-grade silastic products.

(3) complementary part in addition is: a breather pipe [12], a water inlet pipe [17], a valve rubber [14], a cover plate [15], three bolts [16].

After glass liner [13] upside-down mounting, the water inlet difficulty; So must adorn a water inlet pipe [17], so that water inlet.

During water inlet, will produce malleation in the glass liner [13]; When discharging water, will produce negative pressure in the glass liner [13]; So must adorn a breather pipe [12], to eliminate the positive and negative pressure in the glass liner [13].

At glass liner [13] end, put a valve rubber [14]; On valve rubber [14], put a cover plate [15] again; With three bolts [16], with cover plate [15] be connected with pressing plate [9], fastening, glass liner [13] is inverted is fixed between two plates, to solve glass liner upside-down mounting problem.
