Description

The thermos electric quick heater that has little steam valve

The utility model relates to a kind of electric quick heater, particularly a kind of thermos automatic electric quick heater that has little steam valve.

Existing thermos is by electrothermal tube with automatic electric quick heater, thermos cork, magnet, electric contact and float are formed, after thermos was filled water, float come-up energized began heating, after the water boiling, water in the thermos is constantly excessive, and water constantly reduces, and makes float move down, thereby cut off the electricity supply, and can also prevent dry combustion method, but this electric quick heater requires in the course of the work thermos should fill water, if having discontented slightly, so float just can't on float to energized, and must allow after water is boiled water in the thermos is continuous excessively just can cut off the electricity supply, very inconvenience so in use is because after the water boiling, hot water is constantly excessive, completely splash, bring inconvenience to people's life, this product is not suitable for north use in addition, because of mucous membrane can appear in the water quality in the north, so in use, the mucous membrane in the northern water quality can be stained with float gradually, makes float slowly become heavy, arrived certain the time, this float can't float with regard to recuperation, makes it can't energized, cisco unity malfunction.

In order to overcome above-mentioned deficiency, the purpose of this utility model provides the automatic electric quick heater of a kind of improved thermos, particularly a kind of thermos electric quick heater that has little air valve, it need not to adorn water very full of the energy energized, also need not be in the boiled back of water continuous excessively just can cut off the electricity supply, no matter the South and the North can both conveniently use.

The purpose of this utility model realizes by following technical proposals.

The utility model includes electrothermal tube, thermos cork, a pair of electric contact and pair of magnet, electrothermal tube is fixedly connected in the thermos cork, thermos cork is a hollow body of moulding notes, it is characterized in that the fixedly connected hollow posts of thermos cork central authorities, it through thermos cork from the top to the bottom, one little steam valve is arranged in hollow posts, it is made up of a motion bar and a bead, this motion bar is a liftable T shape motion bar, stretch out outside the thermos cork at its top, its fixedly connected flat board in bottom, in the bottom of hollow posts one aperture is arranged, bead is positioned at dull and stereotyped below and places on this aperture, there is a dividing plate outside of hollow posts in thermos cork, electrothermal tube fixedly connected with this dividing plate on, two strip metal connecting rods are arranged, their end all is fixedly connected on the dividing plate, the other end is fixedly connected with electric contact a and electric contact b respectively, the pair of magnet homopolarity arrange in opposite directions and respectively fixedly connected and motion bar and metal connecting rod on, hollow post jamb between two magnet is upper to connect a little iron block, electric contact a in the magnet upper fixed, b connects by lead with electrothermal tube and afterwards inserts power supply.

The utility model is because of containing little air valve, thereby can effectively prevent dry combustion method, in use convenient, safety, health, it need not to adorn water very full of the energy energized, and the water full ground that also can not splash after boiled, use of the present utility model in addition is not subjected to water quality impact, and no matter the South and the North can both normally use.

Below will be described in further detail the utility model by specific embodiment.

Fig. 1 is a structure chart of the present utility model.

Fig. 2 is circuit theory diagrams of the present utility model.

As Fig. 1, shown in Figure 2, the utility model is by electrothermal tube 6, thermos cork 1, little air valve, pair of magnet 9,10, a little iron block 11 and a pair of electric contact a, b forms, thermos cork 1 is a hollow body of moulding notes, its fixedly connected hollow posts of central authorities, this hollow posts is the tetragonal prism 2 of a hollow, it through thermos cork 1 from the top to the bottom, one little air valve is arranged in tetragonal prism 2, it is made up of T shape motion bar 3 and bead 7, T shape motion bar 3 tops are stretched out outside the thermos 1 and with button 13 and are connected, its bottom is a flat board 15, but this T shape motion bar 3 free lifting in tetragonal prism 2, in tetragonal prism 2 bottom center one aperture 16 is arranged, bead 7 is positioned at dull and stereotyped 15 belows and places on the aperture 16, bead 7 is glass marbles, have only like this that bead 7 could be backed down by steam when water temperature reaches 100 ℃, can discharge tetragonal prism 2 rapidly in order to make the hot water that flows into tetragonal prism 2, make the lifting of T shape motion bar 3 sensitiveer, can on the wall of thermos cork 1 and tetragonal prism 2, have aperture respectively, and it is two holes are continuous by conduit, tetragonal prism 2 outsides are moulded and are annotated a dividing plate 14 in thermos cork 1, electrothermal tube 6 fixedly connected with this dividing plate 14 on, two strip metal connecting rods 4, an end of 5 is fixedly connected on respectively on the dividing plate 14, its other end is welded with electric contact a and electric contact b respectively, pair of magnet 9,10 homopolarities are arranged in opposite directions and are fixedly connected on respectively on T shape motion bar 3 and the metal connecting rod 5, at two magnet 9, on the square post jamb between 10 and be positioned at magnet 9,10 upper fixed connect a little iron block 11, make when T shape motion bar 3 is promoted to rise by the steam of boiling water, magnet 10 can firmly be inhaled on little iron block 11, electric contact b is connected with electrothermal tube 6 by metal connecting rod 4, and the other end of electrothermal tube 6 and electric contact a insert power supply by lead.Its operation principle is: the utility model insertion is installed in the thermos of water, and energized presses the button 13, as shown in Figure 1, this moment magnet 9,10 are on the same horizontal level, because of so they are homopolarity mutually exclusive, make metal connecting rod 5 be pushed, electric contact a and electric contact b closure, circuit is connected, electrothermal tube work, water begins to be heated, water vapour constantly rises, and after the water boiling, steam is enough to bead is backed down, make a large amount of steam 16 flow into from the hole, move upward thereby promote T shape motion bar 3, magnet 10 moves upward thereupon, and firmly inhales on little iron block 11, the thrust of metal connecting rod 5 disappears at this moment, make electric contact a, b separates, and circuit disconnects, and electrothermal tube 6 quits work, have only and to press the button 13 once more, circuit could be switched on again, and electrothermal tube just can be reworked, thereby effectively prevents the electrothermal tube dry combustion method.
