Abstract
The utility model relates to an automatic power breaking water heater for water boiling which belongs to the technical field of daily life articles, composed of an electrical heating wire, a water holding device and a cover. The utility model is characterized in that the cover is a shell with a hollow cavity, and a base plate is arranged in the hollow cavity. One side of the base plate is provided with a switching mechanism, and the other side of the base plate is provided with an air-operated chamber. A piston which is arranged in the air-operated chamber is connected with the switching mechanism, and a resetting means is arranged on the switching mechanism. When used for heating water, the utility model can automatically cut off power with no fair of entering water after water is boiling. The automatic power breaking water heater for water boiling has the advantages of long service life, reliable performance, simple structure, low cost and easy fabrication.
Description
The utility model relates to a kind of boiling water water heater that cuts off the power supply automatically, belongs to the daily living article technical field.
At present, the electric heater of selling on the market that boils water, no automatic circuit break function when heating up water with it, needs people's supervision, cuts off the electricity supply immediately after water is opened, and does not note slightly, just burns out heating wire, and life-span weak point, waste electric energy, influence are used.
The purpose of this utility model is to provide a kind of automatic outage water heater, has solved the problem that above-mentioned electric heater exists.
The purpose of this utility model is achieved in that
It is made up of electrical heating wire, water container and lid, its technical essential is that described lid is the cavity housing, in cavity, be provided with substrate, one side of substrate is provided with switching mechanism, the opposite side of substrate is provided with pneumatic chamber, be provided with piston in the pneumatic chamber, piston is connected with switching mechanism, and is provided with resetting means on switching mechanism.
The utility model has the advantages that: when adding hot water with it, can cut off the power supply automatically after water is opened, and not water funk entering, long service life, dependable performance, cost simple in structure are low, are easy to make.
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model perspective view.
Fig. 3 is the utility model structural representation.
Describe the utility model in detail below in conjunction with accompanying drawing.
Automatically the outage water heater is when utilizing heater to heat up water, and the pressure that steam produces backs down switch.It is made up of heater strip 1, water container and lid, and described lid is a cavity housing 4, and being provided with copper clad plate 10(in the cavity housing is substrate), copper clad plate is only at power supply lambda line 14, outlet 12 places leave copper sheet, and copper corrosion is fallen in all the other places, and 14 places are welded with binding post 2 at lambda line.One side of copper clad plate is fixed with pneumatic chamber 8, and pneumatic chamber is offered air admission hole, is provided with piston 9 in the pneumatic chamber.Piston can move up and down in pneumatic chamber, be fixed with self-locking column 13 above the piston, this self-locking column vertically inserts in the hole of making in advance on the copper clad plate, can be tabular, a groove is respectively done in the middle part, two sides of plate, and be provided with in both sides two shell fragments 11,11 ', one end of two shell fragments is stuck in the groove of self-locking column, the other end of two shell fragments is stuck in the slot of conversion copper sheet 5, one end of conversion copper sheet is fixed on the copper clad plate with the gong silk, the other end is a make and break contact, and the centre has slot.Another contact of switch is to make with a rectangle copper sheet 6, and it is welded on lambda line 12 positions of copper clad plate.Reset key 3 is positioned at the top of the gland 7 that resets, and a side on gland top is fixed on the copper clad plate, and is movable.The other end is located on the correspondence position of self-locking column.
Its course of work is as follows: steam passes through air admission hole, enter pneumatic chamber, and to piston generation pressure, piston is moved, and the column of self-locking simultaneously also moves thereupon, when the contact-making surface that moves to shell fragment and self-locking column is positioned at the top of conversion copper sheet, because the elastic force effect of shell fragment, the self-locking column produces a downward power to the conversion copper sheet, and the conversion copper sheet is moved down, and contact disconnects.When switch need reset, can press reset key, reset key is pressed the gland that resets, gland is pressed the self-locking column, the self-locking column is moved, and when the groove position that moves to the self-locking column was positioned at the below of conversion copper sheet, the self-locking column produced a upward force to the conversion copper sheet, make the make and break contact closure of conversion copper sheet, thereby realization water is opened automatic outage.
