A large-flow floating ball floor drain

Abstract

The invention discloses a large-flow floating ball floor drain, which comprises a floor funnel, a floor drain cover, a water retaining pipe, a water guide pipe and an outer casing, a floor drain panel is arranged outside the edge of the upper end of the floor funnel, the upper and lower ends of the water retaining pipe are sealed, and the water retaining pipe is worn on the top At the bottom of the floor funnel, there is a water inlet on the upper end of the water retaining pipe. There is a gap between the upper end of the water retaining pipe and the floor drain cover. The gap between the water retaining pipe and the floor funnel forms an upper water seal groove. There is an overflow channel between the water guide pipe and the water retaining pipe, and the gap between the water guide pipe and the water retaining pipe forms an overflow tank. The upper part of the water guide pipe is provided with a water collecting bucket, and a floating ball is arranged in the water collecting bucket, which is located on the side of the overflow tank. The aqueduct is provided with an overflow port, the outer casing is sleeved outside the water retaining pipe, the lower end of the outer casing is sealed, and the lower side of the outer casing is provided with drainage outlets at intervals along the circumferential direction, and the gap between the outer casing and the aqueduct located below the drainage outlet Form the lower water seal groove. The invention has large drainage volume, fast drainage speed, good sealing effect and can effectively prevent backwater.

Description

technical field [0001] The invention relates to a floor drain, in particular to a large-flow floating ball type floor drain. Background technique [0002] Floor drains are common bathroom components in daily life. Floor drains are often installed in bathrooms, bathrooms or balconies for drainage. The traditional water-sealed floor drain is constructed of a bell jar, like a buckled bowl structure, which is buckled on the outlet of the sewer pipe to form a "U"-shaped water trap, and the water seal in the water trap is used to achieve the sealing effect. However, the water seal of this kind of floor drain is shallow and the amount of water sealed is too small, which will dry up due to factors such as time and dry weather and return to odor. In addition, because the drainage volume of the floor drain is limited, when the water volume is too large, it exceeds the drainage limit of the floor drain. , the water will overflow (called backwater or overflow). SUMMARY OF THE INVENTI...

Problems solved by technology

However, the water seal of this kind of floor drain is shallow and the amount of sealed water is too small. It will dry up due to factors such as time and dry weather and return to odor. In addition, because the drainage volume of the floor drain is limited, when the water volume is too large, it exceeds the drainage limit of the floor drain. , the water will overflow (called reverse water or back overflow)
