Description

A kind of floor drain
Technical field
The present invention relates to the connector or similar device technical field for waste pipe or the object-catching of outlet, specifically relate to A kind of and floor drain.
Background technology
Existing floor drain is made of cast iron mostly, and cast iron color and luster is in rust, and not only appearance is not good enough, and rough surface, Easily get rusty, it is not easy to clean;And the foul smell in sewer is easily accessible to interior.To solve the above-mentioned problems, notification number is The Chinese utility model patent of CN2128261Y discloses a kind of deep water seal deodorant floor drain, and traditional grid type floor drain is carried out Improve, it includes floor drain body, envelope bowl and drain cover, and envelope bowl is directly supported at the water sealing (sealing water) pipe upper end in floor drain body, Huo Zhegu Hang calmly on drain cover.
There are following technical problem for the prior art:1st, the more soft object such as hair enters ground leak with current When, hair, which holds, to be got lodged at the leakage hole of ground drain surface, and leak speed is just slower;If this floor drain is located in bathroom, then in bathing When, bathroom content is also easy to produce ponding;Just needs are artificial at this time cleans up hair at leakage hole etc., then can be by product Water is released, and easily makes hand dirty during bathing, very inconvenient and unhygienic;2nd, the soft material such as hair enters floor drain Behind inside, easily it is stuck in floor drain and results in blockage.
The content of the invention
It is an object of the invention to provide a kind of floor drain, can prevent ponding and blocking.
To reach above-mentioned purpose, base case of the invention is as follows:
A kind of floor drain, including floor drain body, floor drain body is interior to be equipped with leak paths, and floor drain body, which is equipped with, to be used to cover Lou The cover board of aquaporin, cover board are equipped with leakage hole;The filter plate with multiple mesh is equipped with leak paths;Floor drain body is equipped with sky The rubber bumps of the heart, are fixedly connected with power rail in rubber bumps, are equipped with and reset between power rail and the upper surface of floor drain body Spring;Cavity is equipped with floor drain body, power rail is stretched into cavity;It is equipped with leak paths and is pierced by Lou under the drive of power rail The ejection part in water hole;And ejection part is between filter plate and cover board;The lower section of filter plate is equipped with L-shaped support column, and L-shaped support column One end is fixedly connected with the side wall of leak paths;The other end of L-shaped support column is rotatably connected to rotation section, and rotation section is equipped with two A blade being bonded respectively with the upper and lower surface of filter plate;Sliding cavity is equipped with floor drain body, is slidably connected in sliding cavity There is sliding part, sliding part is used under the driving of power rail so that rotation section rotates;It is all provided with the upper and lower surface of filter plate It is useful for the friction protrusion of friction blade.
This programme produce beneficial effect be:
When excessive hair the 1st, is accumulated at leakage hole, the leak speed of leakage hole is slow, jams on rubber bumps with foot at this time, Rubber bumps can drive power rail to move downward, and power rail drives ejection part to be pierced by leakage hole, and then by the hair at leakage hole Ejection, and then accelerate water and flow into leakage hole, and then discharge;It is very convenient, reach and produced when preventing bathing in bathroom The situation of ponding occurs;Need not be very hygienic when bathing to being cleared up at this, without making hand dirty;Only need The material that ejection part ejects is cleaned up after the completion of bathing, it is very convenient.
2nd, rubber bumps are jammed on downwards always, the lower end of power rail can gradually be contacted with sliding part, and power rail can drive cunning The direction of dynamic portion towards rotation section is moved, so that sliding part drives rotation section to rotate, the blade on rotation section can also rotate, And then hair at filter plate mesh will be entered on a small quantity or other soft materials are cut off, prevent long-term accumulation hair herein or Other soft materials of person;And the hair or other soft materials after cutting off can be discharged with current, and then prevent the feelings blocked Condition occurs.
3rd, rotation section is equipped with two blades being bonded respectively with the upper and lower surface of filter plate, the i.e. upper table in filter plate Contacted respectively by blade on face and lower surface, can realize the secondary cut to the hair at filter plate or soft material, The situation for further preventing from blocking occurs.
4th, the friction protrusion for the blade that rubs is equipped with the upper and lower surface of filter plate, can be constantly to therewith The blade of contact is polished, and ensures that blade has certain sharpness.
Preferred solution one:As the further optimization to base case, ejection part include cross bar, supporting rack, taper top, Eject rack, gear;The cavity wall of gear and cavity is rotatablely connected;Power rail includes bar body and is fixedly connected on bar body side wall On bar rack, bar rack and pinion engagement;Cross bar is fixedly connected between ejection rack and supporting rack, and ejects rack and tooth Wheel engagement;Taper comes directly towards the upper surface for being fixedly connected on supporting rack.
Said structure simply realizes power rail when moving downward very much, and the bar rack on power rail can drive Gear rotates, and gear drives ejection rack to move upwards, and ejection rack drives cross bar moves upwards, and then drives and be fixedly connected on The other end of supporting rack of cross bar moves upwards, and the taper top on supporting rack can gradually be pierced by leakage hole at this time, very simply Realize by hair in leakage hole etc. eject.
Preferred solution two:As the further optimization to preferred solution one, the surface of taper top is equipped with multiple protrusions.It is convex The setting risen, primarily to blocking the materials such as the hair dropped into from leakage hole in leak paths so that the material energy such as hair High spot is enough hung over, and then ejects it from leakage hole easy to taper top;Situations such as further preventing from blocking.
Preferred solution three:As the further optimization to base case or preferred solution one, rotation section include Rotational Cylindrical and Gear ring is rotated, rotates the lower end that gear ring is fixedly connected on Rotational Cylindrical;Rotational Cylindrical lower part, which is equipped with, rotates chamber, the end of L-shaped support column Stretch into and rotate intracavitary and the cavity wall rotation connection with rotating chamber;Blade is fixedly connected in Rotational Cylindrical
Said structure simply realizes very much, and Rotational Cylindrical can be sleeved on the end of L-shaped support column, and can be in L-shaped branch The cofree rotation of dagger.
Preferred solution four:As the further optimization to preferred solution three, sliding part includes sliding spring, sliding bar and consolidates Surely the sliding rack of sliding bar side is connected to, sliding rack is engaged with rotating gear ring;The cavity wall of sliding bar and sliding cavity is slided Connection;Sliding bar is fixedly connected with sliding spring away from the one end for rotating gear ring, and the cavity wall of sliding spring and sliding cavity is fixed Connection;Power rail can drive sliding bar to be moved towards the direction for rotating gear ring and to rotate gear ring rotation.
Said structure simply realizes power rail during moving downward very much, can drive sliding bar towards rotation The direction movement of gear ring, and can band during the sliding rack on sliding bar is engaged with rotating gear ring, therefore sliding bar moves Turn moves ring gear against rotation, and then drives and rotated with rotating of rotating that gear ring is fixedly connected so that blade rotation.
Preferred solution five:As the further optimization to preferred solution four, the one end of sliding bar away from rotation gear ring is court The inclined-plane that the direction of sliding spring tilts down;And the position correspondence of the end and power rail.The setting on inclined-plane, is further ensured that Power rail during moving downward can and sliding bar contact of incline plane so that sliding bar moves.
