Description

Deodorization floor drain of preventing back overflow core

Technical field

The utility model relates to floor drain technical field, in particular to a kind of deodorization floor drain of preventing back overflow core.

Background technique

Currently, the Chinese patent that notification number is CN206873601U discloses a kind of floor drain fuse, including tubular interior Cylinder, the upper end of the inner cylinder have water inlet, and the lower end of the inner cylinder has water outlet, sets below the inner cylinder It is equipped with the guide holder fixed with inner cylinder, the guide rod that can be slid up and down in guide holder, institute are equipped in the guide holder It states and is fixed with magnetic patch one in guide holder, the magnetic patch one is located at the outside of guide rod, and the upper end of the guide rod is to be fixed with energy It is enough that by water outlet closed sealing element, the lower end of the guide rod is pierced by guide holder, and the lower end of guide rod is fixed with magnetic patch two, The magnetic patch one is magnetic opposite with the two adjacent sides of the magnetic patch.

In use, the magnetic patch one being set on guide holder is jacked up guide rod by magnetic patch two upwards, is set to Sealing element on guide rod contacts at water outlet and closes water outlet.When water flows into inner cylinder from water inlet, water is fallen in Apply on sealing element and to sealing element with thrust straight down.When water to sealing element apply with thrust be greater than magnetic patch one and magnetic When magnetic force between block two, guide rod is slid downwards, so that generating gap between sealing element and water outlet, and is located in inner cylinder The enough gap discharges between water outlet and sealing element of water energy.

But during water flows through the floor drain fuse, the magnetic impurity being mingled in water can be attached to the top of sealing element Portion.When guide rod moves again up and is used to close water outlet, the magnetic impurity being attached at the top of sealing element and water outlet Mouth touches, so that sealing element can not effectively close water outlet.The foul smell inside pipeline can be from sealing element and water outlet at this time Between gap in enter in inner cylinder, and finally from water inlet overflow.

Utility model content

In view of the deficienciess of the prior art, the purpose of this utility model is to provide a kind of deodorization floor drain of preventing back overflow core, It is not easy to be attached to the top of sealing element with the magnetic impurity being mingled in water, and the foul smell inside pipeline is not easy from water inlet The advantage of spilling.

The above-mentioned technical purpose of the utility model is with having the technical scheme that a kind of deodorization overflow-proof Core, including tubular inner cylinder are leaked, the upper end of the inner cylinder has water inlet, and the lower end of the inner cylinder has water outlet Mouthful, it is provided with the guide holder being fixedly connected with inner cylinder below the inner cylinder, being equipped in the guide holder can lead The guide rod moved up and down into seat, sealing element is provided on the top of the guide rod, and the sealing element is described for closing Water outlet, the guide holder include mounting base and casing, and the mounting base bending is U-shaped, and the both ends of mounting base are fixed It is connected to the bottom of inner cylinder, described sleeve pipe is fixedly connected on the mounting base towards on the end face of the inner cylinder, described to lead It is connected to inside described sleeve pipe to bar sliding, described sleeve pipe is internally provided with spring, and one end of the spring and the guiding The bottom of seat is fixedly connected, and the other end of the spring is connected to the top of the guide rod, and the spring is to the guide rod Apply with upward thrust, so that the sealing element at the top of the guide rod closes the water outlet.

Through the above technical solutions, in use, the spring for being set to inside pipe casing applies with upward guide rod Thrust so that guide rod is moved upward to sealing element and contacts at water outlet and close water outlet.When water is from water inlet into interior When to inner cylinder, water drops down on sealing element and applies sealing element with pressure straight down.When the pressure that water applies sealing element When the sum of gravity of power and guide rod and sealing element is greater than the elastic force that spring applies guide rod, guide rod and sealing element are whole Body moves down, and sealing element releases the closing of water outlet, so that the water in inner cylinder is discharged from water outlet.In this mistake Cheng Zhong, the impurity being mingled in water are not easy to be attached to the top of sealing element, and when sealing element is moved again to inner cylinder side and use When closing inner cylinder, sealing element can effectively seal water outlet, so that the foul smell inside pipeline is not easily accessible inner cylinder In body and finally overflowed from water inlet, meanwhile, be flowed into the water inside pipeline be not easily accessible in inner cylinder and finally from into It returns spilling and comes in the mouth of a river.Mounting base is U-shaped, and the both ends of mounting base are fixedly connected with the bottom of inner cylinder, the installation designed in this way Seat materials are less, and cost is relatively low.

Preferably, through-hole, and the inner cavity of the through-hole connection described sleeve pipe are equipped in the mounting base.

Through the above technical solutions, the air of inside pipe casing can be from through hole when guide rod slides to inside pipe casing The external world is drained into, so that the movement of guide rod becomes more smoothly, efficient.

Preferably, the end of the bottom of the inner cylinder and the mounting base cooperatively forms shoulder block, inside the inner cylinder It is provided with the seal receptacle of annular, and the seal receptacle is pushed against in the shoulder block, the sealing element is for sealing the seal receptacle Inner hole.

Through the above technical solutions, the seal receptacle being set to inside inner cylinder can effectively reduce the bore of water outlet, with This reduces sealing element and produces materials.Seal receptacle is pushed against in shoulder block, so that seal receptacle is not easy to send out in inner cylinder in use Raw axial movement, and sealing element can effectively seal the inner hole in the middle part of mounting base.

Preferably, the side-walls of the seal receptacle offer the placing groove of annular, and the placing groove is internally provided with deodorization Sealing ring, the deodorization sealing ring protrude from the notch of the placing groove and contradict the inner wall of the inner cylinder.

Through the above technical solutions, the deodorization sealing ring being set to inside placing groove can will be between seal receptacle and inner cylinder Clearance seal overflow so that the foul smell and water in pipeline are not easy to return from the gap between seal receptacle and inner cylinder to inner cylinder In.

Preferably, the sealing element is in a circular table shape, and the small end of the sealing element is towards the inner cylinder side.

It, can effectively will be in the middle part of seal receptacle through the above technical solutions, when round table-like sealing element is contacted on seal receptacle Inner hole sealing.

Preferably, open up fluted on the bottom of the sealing element, and the groove width of the groove is to the inner cylinder side It is gradually reduced.

Through the above technical solutions, the groove for being set to sealing element bottom can effectively reduce required for sealing element production Raw material reduces the production cost of the sealing element to a certain extent.

Preferably, lead-in chamfered is provided at the inner wall of the seal receptacle, the lead-in chamfered is close to the sealing element one Side, and the lead-in chamfered is used to be bonded the outer wall of the sealing element.

Through the above technical solutions, the lead-in chamfered being set at seal receptacle inner wall can will be between seal receptacle and sealing element Contact from line contact become face contact, the pressure between seal receptacle and sealing element is reduced with this so that the inner wall of seal receptacle and The outer wall of sealing element is less prone to scratch.
