Odor-resistant floor drain with rotational flow floating ball

Abstract

The invention discloses an odor-resistant floor drain with a rotational flow floating ball. The odor-resistant floor drain is used for draining of places such as residences, hotels and public washrooms. The upper plane of an upper casing of the floor drain is provided with a plurality of water inlet holes which are bent in the horizontal direction and twisted in the vertical direction, the water inlet holes in a first embodiment are integrally twisted towards the inner side in the radial direction, the bending direction of the water inlet holes in a second embodiment is a clockwise direction, and a twist angle alpha is 8-10 degrees. A flow deflector bent in the horizontal direction is arranged above the bottom surface of a lower casing, a water outlet hole of the lower casing is provided with a solid floating ball capable of floating up and down, and a sealing device is disposed between the water outlet hole and the floating ball. The bent type water inlet is adopted, rotary water flow can be generated, the overflowing speed is accelerated, and the drainage speed is improved. According to characteristics that water flow vortexes rotate anticlockwise and rotate clockwise in the Northern Hemisphere and the Southern Hemisphere respectively, the two different embodiments are adopted, and the product designed according to the technical scheme can be applied to different territories of the Southern Hemisphere and the Northern Hemisphere.

Description

technical field [0001] The invention relates to the technical field of indoor sanitary piping devices, in particular to a floor drain with an anti-odor function. Background technique [0002] The floor drain is an indispensable functional component in the drainage system of residences, hotels and public toilets. Because the floor drain is connected to the sewer pipe, it should have the functions of drainage, anti-clogging, isolation of odor gas and organisms in the pipeline, etc. Should be easy to clean. Therefore, preventing clogging, rapid drainage, deodorizing effect, and easy cleaning are important functions that the floor drain should have. Traditional floor drains generally rely on storing a small amount of water in the floor drain to form a water seal to isolate the living space from the underground drainage pipes, which has the effect of blocking odors. However, if the water in the floor drain dries up, it will lose its sealing effect, and the odor gas in the sewer...

AI Technical Summary

Problems solved by technology

However, if the water in the floor drain dries up, it will lose its sealing effect, and the odor gas in the sewer will enter the living space

Moreover, this type of floor drain does not have a barrier effect on parasites in the sewer.

[0003] The Chinese utility model patent with the notification number CN2767512Y discloses "a deodorant floor drain". This kind of floor drain has the characteristics of water seal deodorization and simple structure, but the water seal is easy to dry up and loses the deodorization function

The Chinese utility model patent of notification number CN204491809U discloses "a kind of floating ball water seal deodorant floor drain". For fast drainage speed, hollow floats are generally used. The light weight of hollow floats will affect the sealing and deodorization effect

The Chinese invention patent with the notification number CN105386507A discloses a "buoyancy type automatic sealing odor-proof floor drain". This floor drain is adjusted by a spring device, and the seal is reliable, but the structure is complex and difficult to clean

The Chinese utility model patent with the notification number CN205206012U discloses a "odor-proof floor drain". This floor drain adopts a flow guide seat capable of generating swirling flow and a matching swing leaf cover, and controls the upper and lower valve ports through two springs. The sealing effect is good, but the structure is too complicated and the reliability is difficult to guarantee
