Abstract
The utility model relates to an electric water heater, in particular to a liquid level switch type electric water heater, comprising a bottle plug, an electric heating element and a power supply plug, wherein the electric heating element is fixed at the inner end of the bottle plug; the liquid level switch type electric water heater also comprises a liquid level sensor and a liquid level switch; the liquid level sensor is arranged at the inner end of the bottle plug and extends outside the bottle plug; a lead wire of the power supply plug is connected with the electric heating element by the liquid level switch; and the liquid level sensor is connected with the liquid level switch by a power supply. Since the liquid level sensor and the liquid level switch are arranged, when the bottle plug is inserted into a warm bottle, the liquid level switch can be triggered to conduct a circuit only when the liquid level sensor is contacted with water, therefore, the liquid level switch type electric water heater is very safe.
Description
Technical field
The utility model is a kind of electric heater, particularly a kind of liquid-level switch formula electric heater.
Background technology
Existing electric heater generally all has an electric heating element, and after the energising, the electric heating element heating is boiled water.The shortcoming of this electric heater mainly is that common faults such as short circuit open circuit appear in electric heating element itself easily, can't use so cause electric heater to damage; In addition, in case forget the attaching plug of leaving behind, electric heating element will be switched on always, is dryouied up to water, finally causes the appearance of peril.
Summary of the invention
The purpose of this utility model is to break down easily and cause the defective of peril in order to overcome electric heating element formula electric heater, invents a kind of liquid-level switch formula electric heater.
The purpose of this utility model realizes as follows: described liquid-level switch formula electric heater, comprise bottle stopper, electric heating element and attaching plug, electric heating element is fixed on the inner of bottle stopper, it is characterized in that: also comprise liquid level sensor and liquid-level switch, liquid level sensor is located at the inner of bottle stopper and is extended in the outside of bottle stopper, the lead-in wire of attaching plug is connected with electric heating element by liquid-level switch, and liquid level sensor is connected with liquid-level switch by power supply.
Described bottle stopper is provided with indicator light, indicator light be connected in parallel on two electrodes of electric heating element after resistance is connected.
Described bottle stopper is provided with siren.
Good effect of the present utility model is as follows: because the utility model is provided with liquid level sensor and liquid-level switch, when bottle stopper inserts thermos flask, only just can triggers liquid-level switch when liquid level sensor contacts with water and connect circuit, so as safe as a house.
Description of drawings
Fig. 1 is the utility model structure chart
Among the figure: 1 bottle stopper, 2 electric heating elements, 3 attaching plugs
4 liquid level sensors, 5 liquid-level switches, 6 lead-in wires
7 power supplys, 8 indicator lights, 9 resistance
10 sirens
Embodiment
As shown in Figure 1, described liquid-level switch formula electric heater, comprise bottle stopper 1, electric heating element 2 and attaching plug 3, electric heating element 2 is fixed on the inner of bottle stopper 1, it is characterized in that: also comprise liquid level sensor 4 and liquid-level switch 5, liquid level sensor 4 is located at the inner of bottle stopper 1 and is extended in the outside of bottle stopper 1, and the lead-in wire 6 of attaching plug 3 is connected with electric heating element 2 by liquid-level switch 5, and liquid level sensor 4 is connected with liquid-level switch 5 by power supply 7.
Described bottle stopper 1 is provided with indicator light 8, indicator light 8 be connected in parallel on two electrodes of electric heating element 2 after resistance 9 is connected.
Described bottle stopper 1 is provided with siren 10.
During use, only need bottle stopper is inserted in the thermos flask, energized gets final product again.In case forget the attaching plug of leaving behind, electric heating element can cut off the power supply when water level leaves liquid level sensor automatically, has avoided the appearance of peril.
