Description

Deodorant floor drain

Technical field:

The utility model relates to the technical field of indoor ground drainage devices in buildings, in particular to a floor drain that utilizes hydrodynamic opening and closing to prevent large-displacement flowing water from overflowing out of control, preventing peculiar smell and preventing insects from running back.

Background technique:

At present, the common floor drain devices in the building are composed of a cover plate with a leaking hole and a bowl-shaped gusset fixed on its opposite side. The function of the bowl-shaped gusset to prevent odors and insects from migrating back is: there is a circle of grooves in the inner cavity of the floor drain, and a circle of accumulated water will be formed in the groove when draining, and the lower mouth of the bowl-shaped gusset will be buckled. In the groove, a circle of "water seal" is formed to block the peculiar smell and insects in the sewer. When draining water, after the water exceeds the top of the groove, it will overflow the groove, and the water will be discharged from the gap between the groove and the arc surface of the bowl-shaped gusset plate. This structure has formed two major disadvantages. One is Such a "water seal" structure creates resistance to drainage, making drainage difficult and water volume significantly reduced. Therefore, when people need to increase the drainage (for example, when the water pipe or hose bursts in an emergency, the water flow spreads, or when the bathroom is showered), they often have to remove the cover plate, and in order to prevent debris from clogging, they need to replace it. The hole-shaped cover plate without the bowl-shaped gusset is covered on the sewer pipe mouth, which is very inconvenient to use. The second biggest disadvantage is: when the accumulated water at the "water seal" dries up (for example, when the floor drain is not used for a period of time or when the weather is hot and the water is easy to evaporate), the "water seal" will prevent odors and insects from reversing. no longer exists. The peculiar smell and insects of the sewer will still come back into the room, causing adverse effects on the living and working environment.

Chinese Patent No. 998017620 proposes a deodorant floor drain, in which a cylinder is installed in the inner cavity of the floor drain housing, and a gear rack of a transmission mechanism is installed in the cylinder, and holes are opened on the top and bottom of the cylinder to pass through the shaft. The floating and pressure of water drives the shaft and sealing plate to work. The structure of this patent is complex, and more importantly, the shaft is sleeved with a "0" type sealing ring to prevent water and impurities from entering the cylinder. Because the rubber "0" type sealing ring is in the Frequent friction with the shaft is easy to wear and age, making it lose its sealing function, causing the rack and pinion to fail to work normally, causing the floor drain to fail to open and close, and cannot be used normally.

Contents of the invention

The technical problem to be solved by the utility model is to provide an openable floor drain which is simple in structure, reliable in use, flexible in opening and closing, capable of preventing large displacement water from overflowing, preventing sewer odor from overflowing, and preventing insects from escaping into the room.

In order to solve the above-mentioned technical problems, the deodorant floor drain of the present utility model mainly includes the floor drain body, and there is a step on the inner cavity wall, an upper step on the top, a water outlet on the lower part, and a round water inlet with a water inlet on the upper step. On the cover plate, there is a circular plate with a leaking hole on the lower step. Two earrings with through holes are connected to the right side of the leaking hole on the lower bottom of the circular plate. On the right side of the two earrings, there is a threaded hole on the lower bottom of the circular plate. At the corresponding position, a blocking plate is provided close to the lower bottom of the circular plate. A double clevis with a through hole is connected to the top of the right side of the blocking plate. A central shaft is connected between the two clevis and the four holes of the double clevis, and a screw is connected to one end hole of the elastic element. And it is connected with the threaded hole on the circular plate, and the other end of the elastic element is supported on the lower plane of the blocking plate, and its supporting point is located on the left side of the central axis.

The above-mentioned elastic element is a bow-shaped leaf spring with a through hole at one end. The elastic element can also be an arcuate wire spring with an annular through hole at one end.

The threaded hole on the lower bottom surface of the above-mentioned circular plate can also be a through hole. At this time, the connection mode of the elastic element can be connected by a rivet.

After adopting the above-mentioned structure, the beneficial effect of the utility model is that no external energy such as electricity and heat is needed, and only by means of the drained energy, it not only achieves the purpose of rapid drainage, but also satisfies the function of automatic sealing, and realizes the prevention of tap water leakage. In the case of pipe burst and other situations, the overflow of large-volume flowing water is out of control, the odor of the sewer pipe overflows, and the anti-infestation effect of insects back into the room.
