Description
Technical field
The present invention relates to sanitary equipment technical field, is specifically a kind of odour-proof floor drain.
Background technology
Floor drain, be the important interface connecting sewerage system and flooring, as the vitals of drainage system in house, its performance quality directly affects the quality of room air, control extremely important to the peculiar smell between bathroom, present family all choice for use odour-proof floor drain has eliminated common floor drain.At present, according to the principle of deodorization, odour-proof floor drain can be divided into water-sealing stinking-proof, add a cover deodorization and ball float deodorization.Water-sealing stinking-proof is the most traditional is also feel most, in the structure of floor drain, water storage gulf is emphasis, the sealing of the main hygrometric water of floor drain prevents peculiar smell, but it needs design water storage gulf, add the complexity of pipeline on the one hand, ponding on the other hand in water storage gulf easily produces the harmful microorganisms such as bacterium, also easily grows insect.Add a cover deodorization, just refer to and add a lid on covered ground, prevent the gas in floor drain body from dispersing up by the ground sealing of floor drain like this, but need during each floor drain water flowing to bend over to take lid off, therefore, use cumbersome.Ball float deodorization, is installed a little floater shot at the comb place, lower end of floor drain, utilizes the hydraulic pressure in sewer pipe and air pressure to be withstood by ball float, thus play the effect of deodorization, insect protected, anti-spill-out.As the patent " floor drain " that publication number disclosed on State Intellectual Property Office website is CN103452184B, it is made up of grate plate, upper shell, lower house, joint ring, ball float, water storage bucket, flow-guiding channel, clip guide, when the water of certain flow flows through the spherical bottom of water storage bucket, flow velocity can accelerate, and by the guide functions of guide, by the various foreign material mixed in various deposition in the past and water, flow-guiding channel that be made up of water storage bucket and guide, that have smaller cross-sectional area sum volume is discharged.But in this structure, ball float is a bulb, and it connects and locates all more complicated, and assembly precision is higher, and therefore, cost of production is higher.
Therefore, have also appeared a kind of floor drain lower end that utilizes in prior art and seal the floor drain realizing deodorization object, as the patent " floor drain " that publication number disclosed on State Intellectual Property Office website is CN102535632B, it comprises embedded box, the floor drain frame be arranged in embedded box, be arranged on the filtering cover of floor drain frame upper end, hollow is socketed with and the water seal main body of conducting up and down in floor drain frame, joint pin is provided with in water seal main body, joint pin is connected with seal cover by spring, and the lower surface of seal cover and water seal main body offsets and covers the lower surface of water seal main body.The effect that seal cover is subject to hydraulic pressure moves down, and sewage just starts to extract, because seal cover pull-up is covered again the lower surface of water seal main body by the elastic reaction of spring after sewage is drained.But, this floor drain Problems existing is: the seal cover due to floor drain lower end is the sealing realizing water seal main body lower surface under the elastic force effect of spring, and spring is positioned on the central axis of seal cover, therefore, when moving down under the effect of seal cover at hydraulic pressure, the cover plate of seal cover is stressed unbalanced and run-off the straight easily, thus when seal cover moves on resetting under the action of the spring, the situation that the cover plate that seal cover occurs can not seal with the lower surface of water seal main body; In addition, spring easily produces fatigue after a protracted use, causes spring failure, thus does not more ensure the sealing function of seal cover; Above reason all can cause the forfeiture of floor drain deodorant function.
Summary of the invention
Technical problem to be solved by this invention is, provides a kind of sealing performance better, thus the odour-proof floor drain making deodorant function stronger.
