Safety floor drain with floating cover

Abstract

The invention discloses a safety floor drain with a floating cover, which includes a floor drain seat and a floor drain cover located at the upper end thereof. The structural feature is that the upper end of the floor drain seat is provided with a seat groove, and the floor drain cover is located 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, and there is a preset water inlet gap between the floor drain cover and the bottom surface of the seat groove; There is a drain hole on the drain hole, and a floating cup sealed on its port is arranged on the drain hole; there is a water entry gap on the inner surface of the floating cup corresponding to the floor drain seat, and a water entry gap is left between the floating cup and the bottom surface of the floor drain seat. gap. The floor drain of the present invention is provided with a siphon pipe (9) and combing teeth (63) to reduce drainage impact and noise, overcome the problem of high noise caused by the use of plastic sewer pipes for drainage, and can block small valuables that fall into it by mistake.

Description

[0001] This case is an application for the application date of December 30, 2009, the application number 200910112628.x, and the invention name of the floating cover safety floor drain. Technical field [0002] The present invention involves a kind of floor drain, which is a kind of floor drain that is particularly suitable for indoor use. Background technique [0003] The existing use of the floor drain, the area of the area must be flowing from the end surface of the floor drain cap, and then the water pores on the floor drain lid fall into the floor drain or discharge into the sewer (although the water can be matched from the floor drain cap and the floor drain seat.The gap is leaked, but it is only a small part of the negligible. The gap is not used as a drainage channel, and it is easily closed by the small dirt and sludge in the stagnant water and is closed).There are the following defects in the floor drain cap of this structure: 1. The opening of the water pores is small, ...

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
