Description

Reversely-set electrothermal thermos

The utility model relates to a kind of inversion type electric-heating thermos

The inversion type thermos bottle of multiple automatic water outlet was disclosed in patent announcement, its structure is an inner-tube mouth inverted design down, in the inner bag bottom also is to be provided with entery and delivery port and wireway on the inner-tube mouth stopper, entery and delivery port is respectively equipped with valve, as long as open the work that the valve of import or export can add water or emit water.This thermos bottle is easy to use, and water need not thermos bottle, as long as open outlet valve.

The purpose of this utility model is to utilize a kind of inversion type electric-heating thermos that can heat automatically and cut off the power supply of principle design of inversion type thermos bottle.

Task of the present utility model is finished like this, establish a tongue tube on the top of wireway, be with the float of a band magnet ring on the wireway, the electrothermal tube that is installed on the inner-tube mouth stopper is connected in series with triode-thyristor, tongue tube triggers resistance with silicon controlled and is connected in series, and triggers the exit that resistance is contained in wireway.Add cold water by water inlet during work, move on the float, the tongue tube adhesive, controllable silicon is open-minded, electrothermal tube work, when water was boiled, steam was discharged by wireway, and the triggering resistance that is contained in the wireway exit is heated, resistance variations, controllable silicon is closed, and electrothermal tube quits work.

The utlity model has simple in structure, automatically heating, outage is safe and reliable automatically, and adopts the insulation glass refills, good heat insulation, power saving again also has convenient and healthy characteristics.

Below in conjunction with instantiation the utility model is described further:

Fig. 1. electrical schematic diagram

Fig. 2. the schematic diagram of inversion type electric-heating thermos

With reference to the electrical schematic diagram of Fig. 1, the water inlet of boiler and flowing water Valve adopt magnetic valve 9,14, and unification is controlled by three contact selector switch K, the normally-closed contact of tongue tube 19 is connected with entering water electromagnetic valve 14, normally opened contact is connected with triggering resistance 13, stirs and selects K to the water level of intaking, and begins to add water, liquid level rises, the tongue tube action, the power supply of cut-out water inlet electromagnetism 14 is connected simultaneously and is triggered resistance automatically, trigger controllable silicon, electrothermal tube work; Liquid level descends, and tongue tube automatically resets.This example is intake directly and running water pipe joins, and establishes a pressure switch 12 on water inlet pipe, works as tap water cut-off, and pressure switch 12 is cut off Inlet and outlet water magnetic valve 9,14 electric power loops automatically, shields N in the circuit ₁Be power supply indicator, N ₂Be the hydraulic pressure indicator lamp, N ₃Be the relay indicating light of electrothermal tube 15, electrothermal tube 15 is connected in series with controllable silicon.

With reference to 2: inner bag 5 is selected for use the insulation glass refills to be inverted and is located in the shell 1, is furnished with stopper 7 on the inner-tube mouth, entery and delivery port 11,10 is installed on it, wireway 66 and electrothermal tube 15 are respectively equipped with magnetic valve 14,9 on the entery and delivery port 11,10, water inlet 11 is provided with a pressure switch 12, the top of wireway 6 is provided with tongue tube 19 and air guide port 3, be with the float 4 of a band magnet ring 2 on the wireway 6, water inlet pipe 11 joins with running water pipe, triggers the exit that resistance 13 is contained in wireway 6.

Claims (2)

1, a kind of inversion type electric-heating thermos of forming by shell, inner bag, wireway, entery and delivery port and valve, the top that it is characterized in that wireway is provided with a tongue tube, be with the float of a band magnet ring on the wireway, the electrothermal tube that is installed on the inner-tube mouth stopper is connected in series with triode-thyristor, tongue tube triggers resistance with silicon controlled and is connected in series, and triggers the exit that resistance is contained in wireway.

2, inversion type electric-heating thermos according to claim 1 is characterized in that described valve is a magnetic valve.
