Detailed Description
In order to further explain the technical solution of the present invention, the present invention is explained in detail by the following embodiments.
As shown in fig. 1 to 7, the present invention discloses an overflow structure of a toilet tank, which comprises a toilet main body 1, a tank 2 mounted on the toilet main body 1, and an overflow pipe 3 disposed in the tank; wherein, the rear part of the closestool main body 1 forms a mounting cavity 11, and the water tank 2 is mounted in the mounting cavity 11; a feed valve 4 and a discharge valve 5 are installed in the tank 2 such that water is fed into the tank 2 through the feed valve 4 and the water in the tank 2 is discharged from a discharge passage 12 of the toilet body 1 through the discharge valve 5 to flush a bowl 13 of the toilet body 1. The overflow pipe 3 is opened at the upper and lower ends, and the lower opening of the overflow pipe 3 is communicated with the drainage channel 12 of the toilet body 1, so that when the water in the water tank 1 exceeds the highest position of the overflow pipe 3, the redundant water in the water tank 1 can flow into the drainage channel 12 from the overflow pipe 3 for drainage.
As shown in fig. 3 to 7, a float bowl 6 and a sealing cover 7 which can move up and down are matched in the overflow pipe 3; the floating barrel 6 is positioned above the sealing cover 7, the floating barrel 6 is connected with the sealing cover 7, and the sealing cover 7 movably plugs the opening at the lower end of the overflow pipe 3; therefore, when the water in the toilet water tank 2 does not exceed the highest position of the overflow pipe 3, the sealing cover 7 blocks the opening at the lower end of the overflow pipe 3 under the action of gravity, the air in the water tank 2 cannot enter the drainage channel 12 from the overflow pipe 3, and when the drainage valve 5 is opened for drainage, the air in the water tank 2 cannot enter the drainage channel 12 from the overflow pipe 3 to occupy the drainage space of the drainage channel 12, so that the drainage speed of the drainage channel 12 is high; and when the water in the closestool water tank 2 exceeded the highest department of overflow pipe 3, the unnecessary water can flow into overflow pipe 3 and make flotation pontoon 6 come-up in the water tank 2 this moment, and flotation pontoon 6 come-up and drive closing cap 7 and go up to move in order to open 3 lower extreme openings of overflow pipe, and then unnecessary water just can flow into the drainage channel 12 that gets into closestool main part 1 from 3 lower extreme openings of overflow pipe in the water tank 2 and carry out the overflow. The floating barrel 6 is a barrel-shaped body with the upper end closed and the lower end opened, the top of the sealing cover 7 extends upwards to form a connecting rod 71, and the top end of the connecting rod 71 is connected with the inner top wall of the floating barrel 6 in a threaded manner; an annular retaining edge 31 protruding inwards is formed on the inner wall of an opening at the lower end of the overflow pipe 3, an annular groove 72 is formed on the outer side wall of the sealing cover 7, an annular water stop pad 73 is matched in the annular groove 72, and the outer periphery of the annular water stop pad 73 protrudes outwards out of the annular groove 72; the outer periphery of the annular water stop pad 73 movably abuts against the upper surface of the annular blocking edge 31 to movably block the opening at the lower end of the overflow pipe 3; the bottom of closing cap 7 can downwardly extending have at least two activities to block the jack catch 74 of annular fender edge 31 lower extreme face, like this when flotation pontoon 6 come up and drive closing cap 7 and move up, jack catch 74 can block annular fender edge 31 lower extreme face, guarantees when avoiding flotation pontoon 6 and closing cap 7 to break away from overflow pipe 3 that the lower extreme opening of overflow pipe 3 can be opened.
As shown in fig. 1 to 7, the water tank 2 may include a tank body 21 and a tank cover 22, the tank body 21 is installed on the installation cavity 11 of the toilet body 1, the top of the tank body 21 is open, the tank cover 22 covers the tank body 21 and is open and connected to the tank body 21 in a sealing manner, so that the water in the water tank 2 does not flow out through the gap between the tank cover 22 and the tank body 21, and the overflow pipe 3 is higher in height, and further more water can be stored in the water tank 2. The water tank cover 22 and the water tank main body 21 can be locked and fixed by screws, and a sealing ring 23 is arranged between the water tank cover 22 and the water tank main body 21 to ensure the sealing between the water tank cover 22 and the water tank main body 21.
For improving overflow capacity, cooperation figure 1, it is shown in figure 3 to figure 7, tank lid 22 is equipped with an air vent 221 corresponding to overflow pipe 3 upper end opening, and when water in toilet tank 2 exceeded overflow pipe 3's highest point and made unnecessary water in the water tank 2 flow in overflow pipe 3 like this, the air in overflow pipe 3 can be fast outside air vent 221 drainage water tank 2 to make unnecessary water can flow in drainage channel 12 from overflow pipe 3 more fast in the water tank 2, improved overflow pipe 3's overflow speed, improve the utility model discloses an overflow capacity.
The above embodiments and drawings are not intended to limit the form and style of the present invention, and any suitable changes or modifications made by those skilled in the art should not be construed as departing from the scope of the present invention.
