Description

A kind of directly-heated type vacuum flask

The utility model relates to a kind of vacuum flask, particularly the directly-heated type vacuum flask.

Electric-heating thermos of the prior art all is a tubular type indirect product, and its inner bag visitor amasss between 1.5-3.5 rises, and the time of electric heating boiling water is longer, and the loaded down with trivial details operation of needs could pour into unboiled water in the inner bag when adding unboiled water, and total sense is inconvenient when therefore using.

The purpose of this utility model is intended to avoid the deficiencies in the prior art and provides easily and fast a kind of, both safety, the directly-heated type vacuum flask that can be incubated again.

The purpose of this utility model is achieved in that

A kind of directly-heated type vacuum flask, mainly comprise water-level measuring post pressing plate (2), (3), (7), heat water valve (8), base (11), water tank (14), water tank bearing support (23) and heat-conducting seat decorative roof palte (18), it is characterized in that also comprising heat-insulation layer (15), heat conduction base (19), heat-generating pipe (24) and top cover (1), wherein:

(1) heat-insulation layer (15) state is in water tank (14) circumference, and water tank and water tank bearing support (23) and base (11) are fixing tight, filling-foam plastic, thermal-insulation material in the bag temperature layer.

(2) heat conduction base (19) is fixed on water tank (14) lower end central authorities with the aluminium alloy compression casting moulding with nut (16), contacts with water, directly heating; The rotary casting forming of heat-generating pipe (24) is sleeved in the heat conduction base, does not contact with water.

-described top cover (1) can directly cover or start.

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

Fig. 1 is a contour structures front view of the present utility model

Fig. 2 is a side sectional view of the present utility model

Fig. 3 is circuit theory diagrams of the present utility model

In Fig. 1, Fig. 2,1 is top cover, and 2 is the water-level measuring post top board, 3 is the water-level measuring post pressing plate, and 4 is water-level measuring post, and 5 is handle, 6 is water tank, and 7 is the water-level measuring post lower platen, and 8 is heat water valve, 9 are insulation indication light cover, and 10 are the burner on light lid, and 11 is base, 12 is power switch, and 13 refute pipe for water-level measuring post, and 14 is water tank, 15 is heat-insulation layer, 16 is the heat-conducting seat nut, and 17 is power clip, and 18 is the heat-conducting seat decorative roof palte, 19 are the heat conduction base, 20 is temperature controller, and 21 for conduction heat transfer props up sheet, and 22 is the water tank temperature controller, 23 is the water tank bearing support, and 24 is heat-generating pipe.

During enforcement, with reference to Fig. 1, Fig. 2, by heat-conducting seat nut (16) with heat-conducting seat decorative roof palte (18), heat conduction base (19), temperature controller (20), conduction heat transfer prop up sheet (21) and heat-generating pipe (24) is combined into electro-heat equipment, be fixed on water tank (14) lower end central authorities, water tank foreign country places bag temperature layer (15), and the heat-insulation layer outer wall of water tank periphery is kept water-level measuring post in advance when the die sinking tool, lower platen on the water-level measuring post, water level is plugged into the position of pipe form to observe water level device, then with temperature controller (22), and casing (6), handle (5), top cover (1), heat water valve (8) is formed static housing, will be incubated indication light cover (9) at last, burner on light lid (10), power switch (12), power clip (17), water tank bearing support (23) all is fixed on the base (11).

When unboiled water stream is in heat conduction base (19), be heated and boiling fast, the water of boiling moves upward rapidly and the heat conduction base that produces the contact heating that refluxes once more during the contact portion unboiled water quickens boiling, boiling is right entirely when boiling water, boiling water triggers temperature controller, this moment, electric current cut off automatically, both safe and reliable, health is efficient again.

The utility model compact conformation is reasonable, and the profile elegance is generous, can obtain boiling water safely and fast, is suitable for office, dining room, hotel, workshop and use to family.

Claims (2)

1, a kind of directly-heated type vacuum flask, mainly comprise water-level measuring post pressing plate (2), (3), (7), heat water valve (8), base (11), water tank (14), water tank bearing support (23) heat-conducting seat decorative roof palte (18), it is characterized in that also comprising heat-insulation layer (15), heat conduction base (19), heat-generating pipe (24) and top cover (1), wherein:

(1) heat-insulation layer (15) encloses in water tank (14) circumference, and water tank and water tank bearing support (23) and base (11) are fixing tight, filling-foam plastic, thermal-insulation material in the bag temperature layer,
