Description

A sealed floor drain

technical field

The invention relates to the field of water supply and drainage equipment, in particular to a sealed floor drain.

Background technique

Floor drains play an important role in drainage systems in the construction industry. In addition to the most basic drainage function, the floor drain should also have the functions of deodorization, insect prevention and overflow prevention. Existing floor drains often use water seals to seal the sewer pipes. The common problems are as follows: a. The drainage capacity of the floor drain is weak, and it is prone to unsmooth drainage. b. The structure of the floor drain is unreasonable, resulting in unreliable three-proof function. c. Due to structural defects, dirt is easy to deposit on the water seal trap, causing blockage and difficult to clean. d. The height of the water seal of the floor drain is not enough, generally only 10~20mm, it is easy to dry up, and the positive and negative pressure in the pipeline can destroy the water seal, causing odorous insects to invade the house, polluting the indoor environment, and endangering people's health. the

Contents of the invention

The object of the present invention is to provide a floor drain that has strong drainage capacity, is not easy to deposit dirt, and has good anti-odor and anti-insect effects.

In order to achieve the purpose of the above invention, the present invention adopts the following technical solution: a sealed floor drain, including a drain body cover provided with a plurality of through holes, a main body and a floor drain core, the drain body cover covers the main body, and the floor drain core is arranged in the main body , the inner cavity of the main body is a straight cylinder type; a seal is arranged at the lower end of the main body, and a telescopic mechanism is arranged between the floor drain core and the seal, and the telescopic mechanism can make the seal under the buoyancy of water and its own gravity. Seal or open with the bottom opening of the main body. This structure uses the gravity and buoyancy of water to control the opening and closing of the seal. When draining water, when the resultant force of the gravity of the telescopic mechanism and the buoyancy of the wastewater is greater than the gravity of the telescopic mechanism, the telescopic mechanism moves the seal downward, and the waste water can be smoothly discharged from the floor drain; When the wastewater is discharged less and less, the water level drops, the gravity of the telescopic mechanism is greater than the resultant force of gravity and buoyancy of the wastewater, and the telescopic mechanism also descends, and the buoyancy decreases immediately. Finally, the buoyancy disappears after the drainage is completed, and the sealing element acts on the gravitational force of the telescopic mechanism. Next, press the outlet at the bottom of the main body of the floor drain to achieve a sealing effect. Because the drainage channel of the present invention is a straight-through type, the drainage volume is large, the water is smoothly launched, and dirt is not easy to be deposited. At the same time, under the action of the counterweight, the sealing member and the main body have a tight sealing effect, and the effect of preventing insects and deodorizing is good.

The floor drain core includes a core shell and a core cover provided with a plurality of through holes, the core cover is installed at the bottom of the main body, and the core shell is installed above the core cover.

The telescopic mechanism includes a float, a counterweight, a hinge and a hinge fixing rod, the counterweight is installed on the float, the hinge is fixed in the core shell through the hinge fixing rod, and a through hole is opened on the top of the core shell, and the upper end of the hinge Connected with a support rod, the support rod passes through the through hole on the top of the core shell and is connected with the float, the lower end of the hinge is connected with a support rod, and the support rod passes through the through hole in the middle of the core cover and is connected with the seal; the structure of the hinge telescopic mechanism Simple and easy to install.

The further improvement of the present invention lies in that a circle of protrusions is arranged on the bottom inner wall of the main body, the core cover is arranged above the protrusions, and the sealing member is arranged under the protrusions. On the one hand, the protrusion supports the floor drain core, and on the other hand, it cooperates with the sealing element, so that the sealing effect is better.

A further improvement of the present invention lies in that the lower part of the protrusion is formed into a conical slope, and the sealing member is provided with an outer contour matching the conical slope of the protrusion. The lower surface of the protrusion is inclined, and when the seal is slightly offset in the horizontal plane, the cooperation between the seal and the protrusion can be automatically adjusted, and the sealing effect is good.

The core shell is composed of a buckle-type bowl and a cylindrical body, the lower-button bowl is arranged on the cylinder body, a number of guide ribs are arranged on the bottom wall of the cylinder body, and inserting ribs are arranged on the guide ribs Connect to the inclined surface; the core cover is provided with a matching socket, this structure can prevent dirt from being deposited in the core shell, and is convenient for disassembly and installation.

The float is in the shape of a buckle-down bowl, and the float is provided with an inner cavity matched with the core shell. This structure can prevent dirt from being deposited in the core shell, and is convenient for disassembly and installation.

A cavity is provided in the bowl wall of the down-button bowl-shaped float, and the buoyancy is greater when the volume is the same, saving materials.

The beneficial effects of the invention are: large displacement, smooth water launching, not easy to deposit dirt, good sealing effect, and convenient and simple assembly.

Detailed ways

As shown in Figures 1-6, the sealed floor drain of the present invention includes a drain body cover 1 and a main body 2, the drain body cover 1 covers the body 2, and a plurality of through holes are arranged on the drain body cover 1 to facilitate water flow Flow into the main body 2, the main body 2 is a straight cylinder type, and the main body 2 is provided with a float 3, a counterweight 4, a seal 5, a hinge 6, a hinge fixing rod 7, a core shell 8 and a core cover 9, and in the main body 2 A circle of protrusions 10 is arranged on the inner wall of the bottom, and the inner surface of the lower part of the protrusions 10 forms a conical slope; The conical inclined surface of 10 matches the outer contour. The core shell 8 is composed of a buckle-type bowl and a cylinder. Ribs, the guide ribs are provided with an insertion slope; the core cover 9 is provided with a matching socket, and the core shell 8 is inserted above the core cover 9 through the guide ribs; the top of the core shell 8 has a through hole, and the hinge 6 passes through the hinge. The fixed rod 7 is fixed in the core shell 8, the upper end of the hinge 6 is connected with a support rod, and the support rod is connected with the float 3 after passing through the through hole at the top of the core shell 8, and the lower end of the hinge 6 is connected with a support rod, and the support rod passes through After going through the through hole in the middle part of the core cover 9, it is connected with the sealing member 5.

The working principle of the present invention: use the gravity and buoyancy of water to control the opening and closing of the seal. When draining water, when the resultant force of the gravity and buoyancy of the waste water is greater than the weight of the counterweight 4, the float 3 floats up, and the seal moves down through the hinge 6, so that the waste water can be discharged smoothly into the floor drain; when the waste water is drained less and less, the water level drops , the float 3 also descends, and the buoyancy decreases immediately. The gravity of the counterweight 4 is greater than the resultant force of the gravity and buoyancy of the waste water. Finally, the buoyancy disappears after the water is drained. The seal 5 is under the action of the gravity of the counterweight 4 and the hinge 6. , compress the inclined surface at the lower end of the main body 2 of the floor drain to achieve a sealing effect.
