Floating cover safety floor drain

Abstract

The invention discloses a floating cover safety floor drain which comprises a floor drain seat and a floor drain cover arranged at the upper end of the floor drain seat, and has the structural characteristics that the upper end of the floor drain seat is provided with a seat groove; the floor drain cover is arranged in the seat groove; a preset water inlet gap is formed between the floor drain cover and the side wall of the seat groove of the floor drain seat; another preset water inlet gap is arranged between the floor drain cover and the bottom surface of the seat groove; the lower end of the floor drain seat is provided with a seat bottom which has a discharge hole; the discharge hole is provided with a floating cup used for sealing and pressing the port of the discharge hole; a water inlet gap is reserved at the inner side of the floating cup corresponding to the floor drain seat; another water inlet gap is reserved between the floating cup and the bottom surface of the seat bottom of the floor drain seat. The bottom of the floating cup (3) of the floating cover safety floor drain has a bottom hole (31), the position of the bottom hole (31) corresponds to that of an opening of the discharge hole (14), and the seeper permeating into the floating cup (3) can be discharged in time through the bottom hole (31), so that the technical problem that in the existing floor drain technology, the floor drain can not be reliably used since water seepage is caused after a closed floating ball or the closed floating cup is damaged can be solved.

Description

[0001] This case is a divisional application with an application date of December 30, 2009, an application number of 200910112628.X, and an invention name of a floating cover safety floor drain. technical field [0002] The invention relates to a floor drain, which belongs to a floor drain especially suitable for indoor use. Background technique [0003] In the existing floor drain with a cover, the accumulated water on the ground must flow from the end face of the floor drain cover and then fall into the floor drain from the water hole on the floor drain cover or be discharged into the sewer (although the accumulated water can be drained from the floor drain cover and the floor drain seat) leaked through the gap, but only a negligible small part, the gap is not used as a drainage channel, and is easily blocked by fine dirt and sludge in the stagnant water). The floor drain cover of this structure has the following defects: 1. The opening of the water hole is too small, the ...

AI Technical Summary

Problems solved by technology

The floor drain cover of this structure has the following defects: 1. The opening of the water hole is too small, the orifice is easy to block, the drainage speed of the accumulated water is slow, and the ground water is easy to overflow; 2. The water hole is opened too large, and solid impurities Objects are easy to fall into the floor drain, and it is easy to cause the floor drain or even the sewer to be blocked; the large water hole will also easily make the water in the water-sealed deodorant floor drain dry and lose the deodorant function. 3. The orifice shape, size and quantity of the water hole of the same floor drain cover are usually fixed, even if the size of the water hole is designed to be adjustable, as the application number is 200620165639.6 With the floor drain device, the floor drain cover will always become the bottleneck for the rapid discharge of ground water

[0005] The floor drain removes the floor drain cover or does not install it, the drainage is fast and smooth, and its bottleneck function is eliminated, but it brings new problems, such as: for the water-sealed floor drain, Not only the anti-odor function is lost, if small valuables fall into it, it will cause accidental loss, and slightly larger debris will easily fall into it and easily cause sewer blockage; In the gap of the floating cover type floor drain, it is very easy to get the cover bowl and the floating ball stuck together, making it unable to float normally, making the anti-odor function unreliable, and even unable to drain normally, and the fragile and exposed floating ball is also very easy to be damaged by cleaning tools or The collision of other objects and the deformation and damage caused by trampling on people's feet will have adverse effects on its use.

Especially, if above-mentioned floating cover type floor drain also arranges and uses the floor drain cover of existing form, can bring new problem again to the use of this floor drain, as: local area water falls vertically from the floor drain cover aperture, will directly The impact on the upper part of the floating ball weakens the floating ability of the floating ball and the bowl, and also weakens the resistance of the floating ball to debris jamming, that is, it has an adverse effect on the floating of the bowl and the floating ball; and when the floating ball floats At this time, the upper top surface of the floating ball is easy to lean against the water hole at the lower end of the floor drain cover, which makes the water inlet channel smaller and narrower, resulting in poor water intake, thereby making the drainage speed slower and the bottleneck of the floor drain cover Defects will be more prominent
