In the boiler of the scheme, the inner pot 2 is arranged in the boiler body 3, the water outlet 2011 is formed in the inner pot 2, the valve core 4 is detachably arranged on one side of the water outlet 2011, the valve core 4 can move to open and close the water outlet 2011, the valve core 4 is mainly arranged on the upper side of the water outlet 2011, the valve core 4 can be independently disassembled and cleaned, the valve core 4 is directly placed on the upper side of the water outlet 2011, and other structures are not required to be fixedly installed, so that the valve core 4 can be independently disassembled and installed; a magnetic core 6 is installed on the upper portion of the outer side of the valve core 4, a coil 5 is arranged on the outer side of the valve core 4, the magnetic core 6 can drive the valve core 4 to move through magnetic force, and mainly after the coil 5 is electrified, the magnetic core 6 and the valve core 4 in the coil 5 absorb a magnetic field generated by the coil 5 to generate magnetic force, so that the magnetic core 6 can drive the valve core 4 to move through magnetic force; the valve core 4 closes the drainage port 2011 mainly depends on the gravity of the valve core 4, and under the condition that the coil 5 is powered off, the valve core 4 moves downwards due to the gravity of the valve core 4 to close the drainage port 2011, so that the opening and closing effect of the valve core 4 on the drainage port 2011 is achieved in the whole process.

In the scheme, when the valve core 4 is in the state of closing the drainage port 2011, the bottom end face of the valve core 4 extends outwards for a distance H relative to the bottom end face of the coil 5, wherein the H is more than or equal to 0 mm; the bottom end face of the valve core 4 is flush with the bottom end face of the coil 5, namely H is 0, and the bottom end face of the valve core 4 extends outwards relative to the bottom end face of the coil 5 and is protruded, namely H is more than 0; the two situations ensure that when the valve core 4 is in a state of closing the drainage port 2011, the bottom end face of the valve core 4 does not retract into the coil 5 relative to the bottom end face of the coil 5 to be recessed, that is, the bottom end face of the magnetic core 6 can be located at a position which is flush with the bottom end face of the coil 5 or extends out of a certain position which is protruded downwards, so that the magnetic force generated by the bottom of the coil 5 and attracting the bottom end face of the valve core 4 downwards can be effectively reduced, the magnetic force generated by the bottom of the coil 5 and attracting the bottom end face of the valve core 4 downwards is resistance relative to the magnetic force generated by the magnetic core 6 driving the valve core 4 to move upwards, the valve core 4 is prevented from moving upwards, if the resistance is larger, the magnetic force generated by the magnetic core 6 driving the valve core 4 to move upwards through the magnetic force needs to drive the valve core 4 to move upwards, and the, the corresponding number of turns of the coil 5 is also required to be more, resulting in higher cost of the coil 5; this scheme sets up the bottom terminal surface of case 4 and outwards stretches out a distance H for the bottom terminal surface of coil 5, H is more than or equal to 0mm, make the bottom terminal surface of case 4 or the partly of the bottom of case 4 be located outside coil 5, the magnetic field that produces after coil 5 circular telegram is difficult to concentrate on the bottom terminal surface of case 4, make on the bottom terminal surface of case 4 or the partly of bottom can not produce more magnetic force, be promptly on the bottom terminal surface of case 4 or the partly of bottom is not in the magnetic field of coil 5, can not produce more magnetic force, make magnetic core 6 drive the resistance of case 4 rebound obtain reducing like this, the magnetic force of the vertical actuation that magnetic core 6 drove case 4 rebound just can realize that magnetic core 6 drove case 4 rebound just more for a short time.

In the scheme, when the valve core 4 is in the state of closing the drainage port 2011, the bottom end face of the valve core 4 extends outwards for a distance H relative to the bottom end face of the coil 5, wherein the H is larger than or equal to 0mm, and after the magnetic core 6 drives the valve core 4 to move upwards to open the drainage port 2011, the valve core 4 has two conditions, wherein one condition is that the bottom end face of the valve core 4 extends outwards relative to the bottom end face of the coil 5, namely the bottom end face of the valve core 4 extends downwards for a certain distance, namely the bottom end face of the valve core 4 is positioned outside the coil 5, or the bottom end face of the valve; in another case, the bottom end surface of the valve core 4 is retracted inwards relative to the bottom end surface of the coil 5, i.e. is extended upwards by a distance, i.e. the bottom end surface of the coil 5 is located in the coil 5; when the magnetic core 6 drives the valve core 4 to move upwards to open the drain 2011 and the bottom end face of the valve core 4 is flush with the bottom end face of the coil 5, H is greater than 0, and when H is 0, the bottom end face of the valve core 4 retracts inwards relative to the bottom end face of the coil 5 after the magnetic core 6 drives the valve core 4 to move upwards to open the drain 2011, namely, the bottom end face of the valve core 4 retracts inwards to form a recess, namely, the bottom end face extends upwards for a distance; the two situations can both realize that the magnetic force of the downward attraction generated by the bottom of the coil 5 on the bottom end face of the valve core 4 is reduced, mainly for reducing the magnetic force of the downward attraction generated by the bottom of the coil 5 on the bottom end face of the valve core 4 at the moment after the coil 5 is electrified, namely for reducing the resistance of the magnetic core 6 for driving the valve core 4 to move upwards, the magnetic force required by the magnetic core 6 for driving the valve core 4 to move upwards is smaller, when the valve core 4 is in the process of moving upwards, the distance between the top end face of the valve core 4 and the bottom end face of the magnetic core 6 is smaller and smaller, therefore, the magnetic force of the magnetic core 6 for mutual attraction of the valve core 4 is larger and larger, the influence of the magnetic force of the downward attraction generated by the bottom of the coil 5 on the bottom end face of the valve core 4 on the upward movement of the magnetic core 6 for driving the valve.
