Abstract

The utility model discloses a float ball type floor drain comprising a shell (1), a tubular inner cavity (2) arranged inside the shell, a water leakage cover (3) arranged on the shell to cover the opening at the upper part of the inner cavity, a water leakage hole (7) punched on the water leakage cover, and a water outlet hole(4) at the bottom of the shell; a circular protruding ring (5) is also provided around the periphery of the water outlet hole at the bottom of the shell. The inner cavity is mounted with a float ball (6) in contact with the protruding ring and forms an enclosed environment with the protruding ring. When water is dispelled out, the water is kept in the inner cavity wherein the floating force of the water makes the ball away from the protruding ring and then the water can be dispelled out of the water outlet hole and the protruding ring as well. The water dispelling channel is smooth and water can be quickly dispelled without making the channel clogged. The float ball is easy to be floated, which prevents clogs; when water is completely dispelled, the inner cavity does not hold water and the float ball falls back to the protruding ring and forms an enclosed environment with the protruding ring due to the gravity so as to prevent stinking air from being emitted. In addition, when water returns from drainage, the float ball clogs the water leakage hole so as not to let the water flow out.

Description

The float-ball type floor drain

Technical field

The utility model relates to the floor drain that a kind of sewer is used, and specifically is meant a kind of float-ball type floor drain.

Background technology

At present, traditional floor drain generally is to adopt U type pipe or return mode such as tank and carry out water seal, overflows to prevent foul smell.These floor drains are owing to the path complexity of following water, and following water speed is slower, also accumulates dirt in addition easily, occurs clogging easily, also are difficult to mediation after the obstruction.Also occurred some on the market and adopted ball floats to form floor drains of sealing, the ball float of these floor drains directly drops on the centre bore of floor drain inner chamber, in the inner chamber behind the water, ball float is because top is subjected to hydraulic pressure bigger, and the bottom is subjected to the area of hydraulic pressure less, and it is difficult for floating in inner chamber, might result in blockage.In addition, above-mentioned existing floor drain also exists complex structure, shortcoming that manufacturing cost is high.

The utility model content

The purpose of this utility model is to provide a kind of following water speed fast, simple in structure, the float-ball type floor drain that can not stop up.

For solving the problems of the technologies described above, the technical solution adopted in the utility model is: the float-ball type floor drain, comprise housing, be provided with the inner chamber of tubular in the housing, housing is provided with the Water Leakage cover that covers on the inner chamber upper opening, and Water Leakage cover is provided with leaking hole, and the bottom of housing is provided with weep hole, the bottom of described housing is provided with annular protruding circle at the periphery of weep hole, is provided with in the inner chamber to drop on the protruding circle and with protruding circle to form the ball float that seals.

The interior upper edge of described protruding circle is the spherical that matches with the ball float outer wall.

Described leaking hole is the circular port of diameter less than ball float.

The interior lower edge of described leaking hole is the spherical that matches with the ball float outer wall.

Distance between described protruding circle and the inner chamber wall is less than the radius of ball float.

The diameter ratio of described ball float and protruding circle is 2.5～1.6.

Joint face between described inner chamber bottom surface and the protruding circle is an arc transiting surface

Owing to adopted above-mentioned structure, instantly during water, the inner chamber water, buoyancy of water holds up ball float, and ball float leaves protruding circle, and water can be discharged from protruding circle, weep hole, and drainage channel is very smooth and easy, and following water speed is fast, is difficult for accumulating dirt, does not need mediation.Because protruding circle holds up ball float, behind the water, the ball float bottom is subjected to the area of hydraulic pressure bigger in the inner chamber, and it floats in inner chamber easily, can not result in blockage.When stopping down water, inner chamber is water no longer, and ball float forms sealing dropping under the effect of gravity on the protruding circle and with protruding circle, overflows to prevent foul smell.In addition, during as the sewer backwater, ball float floats and can get lodged on the leaking hole, prevents that water from flowing out.The utility model component are few, simple in structure, low cost of manufacture, easy to use, have very strong practicality and promotional value.

Description of drawings

Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.

Fig. 1 is the three-dimensional assembling drawing of float-ball type floor drain;

Fig. 2 is the sectional view of float-ball type floor drain;

Fig. 3 is the sectional view of float-ball type ground when leaking down water.

The specific embodiment

As shown in Figure 1 and Figure 2, float-ball type floor drain described in the utility model comprises housing 1, be provided with the inner chamber 2 of tubular in the housing 1, housing 1 is provided with the Water Leakage cover 3 that covers on inner chamber 2 upper openings, and Water Leakage cover 3 is provided with leaking hole 7, and water can flow into the inner chamber from leaking hole 7.The bottom of described housing 1 is provided with weep hole 4, and the bottom of described housing 1 is provided with annular protruding circle 5 at the periphery of weep hole 4, is provided with in the inner chamber 2 to drop on the protruding circle 5 and with protruding circle 5 to form the ball float 6 that seals.The density of ball float 6 is littler than water, can float in water.Distance between described protruding circle 5 and inner chamber 2 walls can guarantee like this that less than the radius of ball float 6 ball float 6 can drop on the protruding circle 5, can not be stuck between protruding circle 5 and inner chamber 2 walls.The diameter of described ball float 6 is greater than the diameter of protruding circle 5, and the diameter ratio preferable range of ball float 6 and protruding circle 5 is 2.5～1.6, and this proportion can guarantee ball float 6 buoyancies.The interior upper edge of described protruding circle 5 is the sphericals that match with ball float 6 outer walls, and the interior upper edge of protruding like this circle 5 and ball float 6 outer walls closely cooperate, and can keep sealing effectively, overflow to prevent foul smell.Described leaking hole 7 is diameter circular ports less than ball float 6, and during as the sewer backwater, ball float 6 floats and can get lodged on the leaking hole 7, prevents that water from flowing out.The interior lower edge of described leaking hole 7 is the sphericals that match with ball float 6 outer walls, and the interior lower edge of leaking hole 7 and ball float 6 outer walls closely cooperate like this, can keep sealing effectively, in case non-return water overflows.Joint face between described inner chamber 2 bottom surfaces and the protruding circle 5 is an arc transiting surface, is difficult for accumulating dirt like this, is not easy to occur clogging.

As shown in Figure 3, the utility model in use, water (flow) direction is as shown by arrows, leak down in inner chamber 2 leaking hole of water from Water Leakage cover 3, buoyancy of water holds up ball float 6, and ball float 6 leaves protruding circle 5, water can be discharged from protruding circle 5, weep hole 4, and drainage channel is very smooth and easy, and following water speed is fast.

In a word; though the utility model has exemplified above-mentioned preferred implementation; but should illustrate; though those skilled in the art can carry out various variations and remodeling; unless such variation and remodeling have departed from scope of the present utility model, otherwise all should be included in the protection domain of the present utility model.
