Abstract
The utility model relates to an automatic power cutting device for water outlet of an electric water heater, which comprises a valve body made of non-magnetic materials, a magnetic valve core made of permanent magnetic materials, a magnetic element which is fixed on a housing of the valve body and parallel with a travel cavity of the valve body and a signal giving element used as automatic power cutting. The spacing of the magnetic element and the travel cavity of the valve body can be within the function range of the magnetic valve core which can be limited in the travel cavity of the valve body by a positioning sheet on the upper part of the valve body and a positioning sleeve on the lower part of the valve body to be moved. A plurality of small holes are arranged on the positioning sheet for water flow to pass through. The utility model has the advantages of simple structure, high sensitivity, small size and low cost.
Description
The utility model relates to a kind of water outlet auto-power-off device of electric heater.
Advantages such as at present, electric heater is with its safety, and is easy to use have obtained using widely, but electric heater leaky in use is the problem that consumers in general relatively worry.In order to address this problem; nearly all electric heater all is equipped with earth leakage protective device; but in use still there is unsafe factor, the water outlet auto-power-off device is installed then can be in use cut off the electricity supply automatically, thoroughly stop the generation of leaky.The flip flop equipment of the water outlet auto-power-off device of existing electric heater is a lever-type structure, it utilizes the sheet metal of water impact lever one end, thereby the magnet ring that causes the other end moves, reed in the triggering tongue tube sends signal and cuts off the electricity supply, this structure need just can cause the displacement of magnet ring usually under bigger water impact, therefore its remolding sensitivity is lower, and the volume of whole device is also bigger.In addition, after using a period of time,, make the performance of cutting off the power supply automatically reduce greatly because the various piece that triggers lever that accumulates in of iron rust in impurity in the water and the water pipe causes the sensitivity of flip flop equipment further to reduce.
The purpose of this utility model provides a kind of simple in structure, and is highly sensitive, the electric heater water outlet auto-power-off device that volume is small and exquisite.
The utility model comprises the valve body that a nonmagnetic substance is made, magnetic spool by the permanent-magnet material making, be fixed on the magnetic excitement element parallel on the valve shell with valve body an actor's rendering of an operatic tune, signal as automatic outage provides element, the spacing of magnetic excitement element and valve body an actor's rendering of an operatic tune should be in the sphere of action of magnetic spool, and the spacer on valve body top and the positioning sleeve of valve body lower portion can be limited to spool in valve body an actor's rendering of an operatic tune and move, have some apertures on the spacer, current are passed through.Its operation principle is such: when not having current to pass through, the magnetic spool is positioned at the bottom of valve body under the gravity effect, and electric heater is in heated condition; And as current when valve body lower portion flows into, the magnetic spool is pushed rising, triggers magnetic excitement element, sends signal, thereby cuts off the electricity supply, and has guaranteed safe in utilization.
The utility model has the advantages that simple in structurely, highly sensitive, volume is little, and cost is low.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of valve body of the present utility model and tongue tube position.
Wherein, 1 valve body, 2 magnetic spools, 3 tongue tubes, 4 banking stops, 5 positioning sleeves, 6 permanent magnets, 7 fins.
Below in conjunction with accompanying drawing and by embodiment the utility model is further described.
The utility model comprises the valve body 1 that a nonmagnetic substance is made, be fixed on the tongue tube parallel 3 on the valve shell with valve body an actor's rendering of an operatic tune, signal as automatic outage provides element, tongue tube 3 should be in the sphere of action of magnetic spool 2 with the spacing of valve body an actor's rendering of an operatic tune, it is characterized in that, this device also comprises the magnetic spool of being made by permanent-magnet material 2, the spacer 4 on valve body top, the positioning sleeve 5 of valve body lower portion, spacer 4 and positioning sleeve 5 can be limited to the magnetic spool in valve body an actor's rendering of an operatic tune and move, have some apertures on the spacer 4, current are passed through.Wherein, magnetic spool 2 is the post pyramidal structure, and shell is that nonmetallic materials are made, a built-in permanent magnet 6, and housing parts also has three fins 7, closely cooperates with valve body an actor's rendering of an operatic tune, can slide up and down, and allow current pass through.
