When water is stored around the lower end of the floor drain sealing device and the height of the stored water exceeds the thickness of the annular silica gel sealing washer 18, the stored water enters the inner side of the lifting cover disc 5 through the water through hole 16 and the water through hole 18 at the lower edge of the lifting cover disc 5, after the stored water at the inner side contacts the lowest point of the water level probe 12-1 and the lowest point of the water level probe 12-2 with preset height, because 1 salt bag is respectively fixed at the edges of the water through hole 16 and the water through hole 17 at the inner side of the lifting cover disc 5, salt in the salt bag can be dissolved in water, the stored water at the inner side of the lifting cover disc 5 has conductivity, the water level probe 12-1 and the water level probe 12-2 are communicated with the base of the lifting cover disc 5 through salt water, the circuit enters a closed state, and the current direction is the battery pack 20 → electric wire → DC electromagnet 14 → electric wire → water level probe 12-2 → salt → base of the lifting cover disc 5 → salt water level probe → water level probe 12-1 → electric wire 11 → switch (normally closed) 21 → electric wire → battery pack 20, the DC electromagnet 14 generates magnetic attraction force to the position control board 15 after being electrified, the attraction force is larger than the torsion force of the reset torsion spring of the position control board 15 and the sum of the friction force between the top end of the round rod of the lifting cover disk 5 and the position clamping cylinder on the position control board 15, so that the position clamping control board 15 rotates along the axial direction of the DC electromagnet 14, the position clamping cylinder on the position clamping control board 15 is separated from the top end of the round rod of the lifting cover disk 5, the control device unlocks, the lifting cover disk 5 drives the lower annular silica gel sealing washer 18 to instantly bounce and move upwards under the action of the pulling force of the power spring 13, the annular silica gel sealing washer 18 is separated from the ground, the top end of the round rod on the lifting cover disk 5 is contacted with the upper buffer rod 8, the upper buffer spring 9 is compressed, and the motion stops when the upper side surface of the base of the lifting cover disk 5 is contacted with the lower end of the central guide tube 7, the buffer rod 8 stops moving upwards at the same time, and the buffer rod 8 pushes the normally closed switch (spring leaf) 21 above the buffer rod open. In the transient process that the lifting cover plate 5 is instantly bounced and the normally closed switch (spring piece) 21 is jacked open, the electrified circuit is thoroughly disconnected, the leg part at the lower end of the sleeve 1 is in contact with the ground to support the whole device, and the floor drain sealing device releases the sealing of the floor drain and starts automatic drainage. When the floor drain needs to be sealed again, the handle 19 is pulled to reset the sealing device.

Two methods for checking the validity of the automatic drainage function of the embodiment are as follows: the first inspection method is that the floor drain sealing device is set to the sealing state, a normally-off switch button 23 is pressed, normally, a normally-off switch (spring leaf) 22 is closed, a circuit enters the closed state, the current direction is battery pack 20 → electric wire → direct current electromagnet 14 → electric wire → normally-off switch (spring leaf) 22 → electric wire → normally-closed switch (spring leaf) 21 → electric wire → battery pack 20, magnetic attraction is generated after the direct current electromagnet 14 is electrified, the control device is unlocked, the sealing device releases the sealing of the floor drain, and enters an automatic drainage state, otherwise, the floor drain sealing device belongs to an abnormal condition, retry is performed after the battery is replaced, and further inspection is performed if necessary; the second inspection method is that the floor drain sealing device is kept in a sealing state relative to the floor drain during bathing, and if the floor drain sealing device automatically turns into a drainage state along with the increase of accumulated water around the floor drain, the floor drain is normal, otherwise, the floor drain sealing device is abnormal. The two test methods are preferably used alternately.
