Under normal conditions, the local drain is arranged at the opening of a sewer pipe, surface accumulated water enters the upper part of the sealing cover 300 through the water inlet 110, the accumulated water acts on the sealing cover 300, the sealing cover 300 moves downwards and opens the water outlet 120, and the accumulated water is discharged into a sewer pipe from the opened water outlet 120; after the accumulated water is discharged, the repulsive force between the first magnet 213 and the upper magnet 3311 and the attractive force between the first magnet 213 and the lower magnet 3313 reset the sealing cover 300, so that the upper end surface of the sealing cover 300 is tightly attached to the water outlet 120, the water outlet 120 is sealed, and after the floor drain does not drain water or the drainage is finished, the gas in the sewer pipeline is not easy to rise back to the indoor, and the deodorization is realized.
Under abnormal conditions, such as alternate seasons or rainy days and the like, when the external air pressure is reduced, the air pressure in the sealing section is higher relative to the external air pressure, when the acting force of the air pressure difference is greater than the gravity of the floating ball 410, the floating ball 410 rises, so that the first through hole 311 is communicated with the second through hole 312, namely, the sealing section is communicated with the outside, the atmospheric pressure of the sealing section is the same as or close to the external atmospheric pressure, the sealing cover 300 can normally move up and down, when the atmospheric pressure of the lower sealing section is balanced with the external atmospheric pressure, the acting force of the air pressure difference is smaller than the gravity of the floating ball 410, the floating ball 410 falls back to reset and seals the first through hole 311, at the moment, the sealing cover 300 can normally move up and down, and the purpose of discharging accumulated water at the.
Meanwhile, in the process that surface water enters the upper part of the sealing cover 300 through the water inlet 110, part of the surface water easily enters the stroke cavity 310 from the second through hole 312, the floating ball 410 floats on the water surface in the stroke cavity 310 due to the fact that the density of the floating ball 410 is smaller than that of the water, the floating piece 400 moves up and down along with the height change of the water surface in the stroke cavity 310, and the surface water entering the stroke cavity 310 is discharged into a sewer pipe from the second through hole 312; after accumulated water entering the stroke cavity 310 is discharged from the first through hole 311, part of the accumulated water enters the cavity 131 through the outer wall of the guide rod 330 and the first air passage 2111, the accumulated water in the cavity 131 can be discharged to a sewer from the third through hole 1311, and after the accumulated water in the stroke cavity 310 is emptied, the floating piece 400 seals the first through hole 311 by means of self gravity.
The above description is intended to be illustrative of the present invention and not to limit the scope of the invention, which is defined by the claims appended hereto.
