Detailed Description
The present invention will be further described with reference to the accompanying drawings and examples.
Example 1
As shown in fig. 1-3, the automatic water feeding water supply machine has an upper portion in a water tank of the water supply machine communicated with a water supply pipe 1, a water outlet of the water supply pipe 1 is provided with an electromagnetic valve 2, a lower portion of the water outlet of the water supply pipe 1 is sequentially provided with a high liquid level switch 3, a low liquid level switch 4, an alarm liquid level switch 5 and a disconnection liquid level switch 6 from top to bottom, a heating resistor 7 is arranged at the bottom in the water supply machine, the upper portion of the heating resistor 7 is provided with a temperature control switch 8, the alarm liquid level switch 5 is at the same height as the temperature control switch 8, and the disconnection.
One end of a normally closed contact of the low liquid level switch 4 is connected to the positive pole of a power supply, the other end of the normally closed contact is connected to the negative pole of the power supply through a coil of a relay K1, a control coil of the electromagnetic valve 2 is connected to the power supply through a first normally open contact of a relay K1, one end of a second normally open contact of a relay K1 is connected to the negative pole of the power supply through a coil of a relay K1, and the other end of the normally closed contact of the relay K2;
one end of a coil of the relay K2 is connected to the negative pole of the power supply through a normally open contact of the high liquid level switch 3, and the other end of the coil is connected to the positive pole of the power supply;
one end of a coil of the relay K3 is connected to the positive electrode of the power supply through a normally closed contact of the alarm liquid level switch 5, the other end of the coil is connected to the negative electrode of the power supply, and power ends of the buzzer and the alarm lamp are respectively connected to the power supply through two normally open contacts of the relay K3;
the coil one end of relay K4 is connected to the positive pole of power through the normally closed contact that breaks off level switch 6, and the other end is connected to the power negative pole, and relay K4's normally open contact one end is connected to the positive pole of power through temperature detect switch 8, and relay K4's normally open contact other end is connected to the power negative pole through heating resistor 7 power end.
The working principle is as follows:
under the normal condition, the water supply machine water tank liquid level should be in between the position that high liquid level switch 3 and low liquid level switch 4 are located, can cause liquid level switch to shift when the water level is higher than liquid level switch, can cause liquid level switch playback when the water level is less than liquid level switch. The water level is normally maintained between the high level switch 3 and the low level switch 4, and then the low level switch 4, the alarm level switch 5 and the off level switch 6 are all in a displaced state.
When using water gradually, the water level is low to below low liquid level switch 4, make low liquid level switch 4 playback, the normally closed contact of low liquid level switch 4 that is in the off-state is closed, make relay K1's coil electrified, two normally open contacts of relay K1 are closed, relay K1's first normally open contact closure makes solenoid valve 2 opened, put through the water pipe, water gets into the box and supplements, the liquid level risees, when the liquid level is higher than low liquid level switch 3, low liquid level switch 4 shifts once more, low liquid level switch 4's normally open contact disconnection, but relay K1's second normally open contact closure makes relay K1's coil and power switch-on all the time, relay K1's normally open contact keeps closed, battery valve 2 keeps opening, the liquid level lasts to rise. Until the liquid level is higher than the high liquid level switch 3, make the high liquid level switch 3 shift, the normally open contact of high liquid level switch 3 is closed, and the coil of relay K2 gets electric, and the normally closed contact of relay K2 breaks off, makes relay K1's coil and power disconnection, and the normally open contact of relay K1 breaks off, and solenoid valve 2 closes, and the water level keeps.
If the water level continuously drops below the low liquid level switch 4, the electromagnetic valve 2 is opened, and water is cut off, so that the water cannot be supplemented, and the water is gradually reduced along with the use. Until the liquid level drops to temperature detect switch 8 department, warning liquid level switch 5 and temperature detect switch 8 are co-altitude, when the water level drops below warning liquid level switch 5, warning liquid level switch 5 playback, the closed state that the normally closed contact that is in the disconnection of warning liquid level switch 5 returns makes relay K3's coil electrified, relay K3's normally open contact is closed, buzzer and pilot lamp simultaneous working is reported to the police, if someone discovers the warning, the cut-off power supply can, can automatic water supply after treating the incoming water. If still no one can understand, or do not know what the alarm means, continue to receive water, the water level can be lower than temperature control switch 8, and temperature control switch 8 can not monitor the temperature and disconnect heating resistor 7. Until the water level drops to heating resistor 7 department, disconnection liquid level switch 6 and heating resistor 7 are with the same height, and the water level drops to below the heating resistor 7, and heating resistor 7 can dry combustion method, and the liquid level also can be less than disconnection liquid level switch 6 this moment, and disconnection liquid level switch 6's normally closed contact returns the closed state by the off-state, and relay K4's coil is electrified, and relay K4's normally closed contact disconnection, with heating resistor 7 and power disconnection, realize preventing dry combustion method.
Of course, the above description is only a preferred embodiment of the present invention, and should not be taken as limiting the scope of the embodiments of the present invention. The present invention is not limited to the above examples, and the technical field of the present invention is equivalent to the changes and improvements made in the actual range of the present invention, which should be attributed to the patent coverage of the present invention.
