The detailed connection means is a technique known in the art, and the following main description is provided for the working principle and process, and specifically provided for the following:

as can be seen from the drawings of the specification and the description of the figures 1-5, when the floor drain is installed, firstly, the floor drain shell, namely the water outlet pipeline 1, the water inlet pipeline 6 and the necking pipeline 19 are buried underground, the water outlet pipeline 1 is connected with an external output pipe, and the upper edge of the water inlet pipeline 6 is flush with the ground; the water inlet pipeline 6 is characterized in that a limiting plate 15 is placed on a fixing ring 16 on the inner wall of the water inlet pipeline 6, a limiting hole 22 is formed in the limiting plate 15, the limiting hole 22 movably penetrates through a limiting rod 17, a buoyancy block 14 is arranged at the upper end of the limiting plate 15, a sealing cover 4 is arranged at the lower end of the limiting plate, a clamping plate 2 is arranged on the inner wall of a necking pipeline 19, a groove 18 is formed between the clamping plate 2 and the necking pipeline 19, the limiting rod 17 moves up and down in the limiting hole 22 of the limiting plate 15, when the limiting plate moves to the lowest end, the lower end of the sealing cover 4 can extend into the groove 18 and is isolated from the water outlet pipeline 1 and the water inlet pipeline 6 through the clamping plate 2 and the necking pipeline 19; a step platform 13 is arranged at the central position of the water inlet pipeline 6, the filter screen 7 is arranged on the step platform 13, the upper surface of the filter screen 7 is pressed with an anti-pressure cover 12, and a handle 11 on the filter screen 7 is convenient to mount and dismount; the utility model can be disassembled, thereby being convenient for cleaning after blockage or repairing after damage.

When the water-saving toilet is in operation, water on the floor of a toilet flows into the water inlet pipeline 6 from the long-strip water outlet 9 on the gland 12, flows through the filter screen 7, blocks impurities such as hair, flows downwards and flows downwards from the round water outlet 21 on the limiting plate 15, the compression spring 5 is arranged between the upper surface of the sealing plate and the lower bottom surface of the limiting plate 15, the sealing ring 3 arranged below the sealing cover 4 is attached to the clamping plate 2 by the reaction force of the compression spring 5, the flowing water slowly rises and gradually rises to the buoyancy block 14, and the buoyancy of the buoyancy block 14 is greater than the maximum elastic force of the compression spring 5, so that the water surface rises, the buoyancy block 14 rises, the compression spring 5 is compressed, the sealing cover 4 and the sealing ring 3 rise, the sealing ring 3 and the clamping plate 2 form an opening, and the water flows to the water outlet pipeline 1 and is discharged to an external output pipe; when no water is on the ground of the toilet, water does not enter, when the water surface is lower than the lower bottom surface of the buoyancy block 14, the sealing ring 3 is attached to the clamping plate 2 under the reaction of the compression spring 5, the water does not descend, the sealing cover 4 isolates the water outlet pipeline 1 from the water inlet pipeline 6, and the reserved water also isolates the air reversely coming from the water outlet pipeline 1 from the toilet; it should be noted in particular that even though in actual use, the remaining water may slowly flow away from the small gap between the sealing ring 3 and the clamping plate 2, the water in the groove 18 between the clamping plate 2 and the throat pipe 19 will also make the sealing between the sealing ring 3 and the clamping plate 2 and the throat pipe 19 better, automatically isolating the floor drain outlet pipe from the toilet space.

In the use process, if sundries on the filter screen 7 are too much, a sewer floor drain can be blocked, at the moment, a person can rotate the screwing ring 20 in the hidden groove 8 on the upper surface of the pressing cover 12 to take out, the pressing cover 12 is rotated, the scraping rod 10 on the lower bottom surface of the pressing cover 12 can drag and rotate sundries such as hair and the like on the upper surface of the filter screen 7, the sundries such as hair and the like flowing into a net opening of the filter screen 7 are pulled out, and the cleaning is convenient.

The pressing cover 12 and the limiting plate 15 are made of stainless steel materials and have certain weight, so that the installation is relatively stable.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
