Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be described in detail below. It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

The invention will be further described in the following with reference to specific embodiments thereof,

as shown in fig. 1-5, a floating ball floor drain with anti-backflow function comprises a floor drain housing 1 and a floor drain cover 2 installed on the upper end of the floor drain housing 1, wherein the floor drain housing 1 comprises a first connection port 11 for installing the floor drain cover 2 and a receiving pipe 12 formed at the lower end of the first connection port 11, a floor drain inner pipe 3 is installed in the floor drain housing 1, the floor drain inner pipe 3 comprises a second connection port 31 matched with the first connection port 11 and a water inlet pipe 32 formed at the lower end of the second connection port 31 and entering the receiving pipe 12, a hollow floating ball 4 is installed in the water inlet pipe 32, a first limit retainer ring 321 and a second limit retainer ring 322 for limiting the floating ball 4 are respectively formed at the upper end and the lower end of the water inlet pipe 32, an overflow cup 5 located at the lower end of the floor drain inner pipe 3 is further installed at the lower end of the floor drain housing 1, a cavity 51 capable of accommodating the water inlet pipeline 32 is formed in the overflow cup body 5. Specifically, after water flows into the floor drain inner pipe 3 through the floor drain cover 2, the water flows into the overflow cup 5 through the water inlet pipe 32, and continuously rises in the overflow cup 5 until the water level in the overflow cup 5 exceeds the height of the overflow cup 5, and the water overflows from the overflow cup 5 to the accommodating pipe 12, and finally flows out of the accommodating pipe 12. When the water flow is too large, the rising speed of the water in the overflow cup body 5 exceeds the overflow speed of the water, the water rises into the water inlet pipe 32, so that the floating ball 4 in the water inlet pipe 32 is subjected to buoyancy and starts to float up until the floating ball abuts against the first limit retainer ring 321 above the floating ball, the water cannot continue to rise, the water is prevented from finally flowing back out of the floor drain, and at the moment, the water in the overflow cup body 5 continues to overflow and flows out of the accommodating pipe 12. As the water continuously flows out of the accommodating pipe 12, the water level in the overflow cup 5 and the water inlet pipe 32 continuously drops, the floating ball 4 also drops, and the water flow can continuously enter the water inlet pipe 32, wherein the second limit retainer 322 is used for preventing the floating ball 4 from sinking to be separated from the water inlet pipe 32.

Further, the diameter of the floating ball 4 is smaller than the inner diameter of the water inlet pipe 32. Specifically, a gap should be left between the floating ball 44 and the water inlet pipe 32, so that the floating ball 4 can smoothly float up and down in the water inlet pipe 32 without rubbing against the inner side wall of the water inlet pipe 32, and the floating ball 4 is prevented from being subjected to resistance from the water inlet pipe 32 in the process of floating up and down.

Further, the diameter of the floating ball 4 is larger than the inner diameters of the first limit stop ring 321 and the second limit stop ring 322. Specifically, the first limiting retainer ring 321 needs to be capable of preventing the floating ball 4 from separating from the water inlet pipe 32 and contacting with the floor drain cover 2 in the floating process, and the second limiting retainer ring 322 needs to be capable of preventing the floating ball 4 from separating from the water inlet pipe 32 and contacting with the overflow cup 5 in the descending process, so that the inner diameters of the first limiting retainer ring 321 and the second limiting retainer ring 322 should be smaller than that of the floating ball 4.

Further, the inner diameter of the cavity 51 is larger than the outer diameter of the inlet pipe 32. Specifically, a gap should be left between the cavity 51 and the water inlet pipe 32, so that the overflow amount of water from the overflow cup body 5 can be increased, and the speed of water flowing through the floor drain is increased.

Further, the outer diameter of the cavity 51 is smaller than the inner diameter of the accommodating tube 12. In particular, a gap should be left between the cavity 51 and the accommodating pipe 12, so that the throughput of water from the accommodating pipe 12 can be increased, and the speed of water flowing through the floor drain can be further increased.

As shown in fig. 5, the floor drain cover body 2 is formed with first filtering openings 21 uniformly distributed in a net shape. Specifically, the first filtering port 21 can filter impurities in water flow before entering the floor drain, so that blockage of a water pipe is avoided.

As shown in fig. 4, the second connection port 31 includes a bowl-shaped water collection groove 311 formed at an upper end of the water inlet pipe 32, and the water collection groove 311 and the first limit stopper 321 define a water inlet port 312. Specifically, the water collecting groove 311 may contain a certain amount of water after the floating ball 4 blocks the water inlet port 312, and when the water level in the overflow cup 12 and the water inlet pipe 32 drops, the water staying in the water collecting groove 311 may apply a downward pressure to the floating ball 4, so as to accelerate the drop of the floating ball 4 in the water inlet pipe 32 and also accelerate the speed of water flowing through the floor drain.

As shown in fig. 3 to 5, a limiting end 111 is formed on the first connecting port 11, a connecting retaining ring 313 is formed on the water collecting tank 311 and is located between the limiting end 111 and the floor drain cover 2, and aligned connecting through holes 22 are formed on the limiting end 111, the connecting retaining ring 313 and the floor drain cover 2. Specifically, the connection between the floor drain shell 1, the floor drain cover body 2 and the floor drain inner pipe 3 can be reinforced by adding the connecting nails into the connecting through holes.

As shown in fig. 1-5, a support collar 52 is formed at the lower end of the overflow cup 5, a water outlet pipe 13 located at the end of the accommodating pipe 12 is formed on the floor drain shell 1, and the inner diameter of the support collar 52 is larger than the inner diameter of the water outlet pipe 13. Specifically, since the supporting retainer ring 52 can support the overflow cup 5 in the accommodating pipe 12, the supporting retainer ring 52 needs to stand on the lower inner wall of the accommodating pipe 12, so the inner diameter of the supporting retainer ring 52 needs to be larger than that of the outlet pipe 13, and when water flows over the overflow cup 5, the water finally flows out of the outlet pipe 13.

Further, the supporting retainer ring 52 is formed with second filtering openings 521 uniformly distributed. Specifically, the second filtering port 52 can perform secondary filtering on the water overflowing from the overflow cup body 5, further remove impurities in the water, prevent the water pipe from being blocked, and finally flow out of the water outlet pipe 13 after the water passes through the second filtering port 52.

The above-mentioned embodiment is only the preferred embodiment of the present invention, and does not limit the protection scope of the present invention according to this, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
