Produce living needs.Due to the peculiar smell in drainage pipeline easily by floor drain reflux between bathroom etc., peculiar smell reflux is by serious shadow
Ring the living environment of the air quality and people between bathroom.The family having in daily life also has floor drain and turns one's coat feelings sometimes
The generation of condition, has brought many worries.In order to improve the peculiar smell reflux and problem of turning one's coat of floor drain, it has been developed that respectively
The odour-proof floor drain of the form of kind：
For example, some floor drains are internally provided with water seal, under retaining state, water seal can be intercepted from drainage pipeline reflux
Peculiar smell, but if water body in floor drain dries up, then floor drain will lose water seal resistance, now peculiar smell can directly by ground
Leak reflux to interior.In addition if there is the situation of turning one's coat, water seal floor drain cannot then be solved.
Again for example, some floor drains set check (non-return) valve, such as eccentric block in bottom, when there is current to pass through, eccentric block is opened,
When non-water flow passes through, eccentric block closure now can effectively intercept the peculiar smell from drainage pipeline reflux, but eccentric block easily collects
Poly- dirty and hair etc., dirty and hair is easily caused eccentric block failure, likewise, that silica gel material makes, reverse turning bed structure,
Using magnet or spring as after draining return etc. check valve structure floor drain, caused by having a dirty and hair being collected
The situation of failure occurs, and people often have no knowledge about after failure, the occurrence of so easily cause anti-taste, work(of turning one's coat
Can similarly fail.
Again for example, existing floater type floor drain also has many deficiencies, such as one be have the shortcomings that with check valve structure it is same；
Two is float the phenomenon of interim card, the row of causing will occurs lower water is slightly larger by collector nozzle absorption in collector nozzle or easily
Water is not smooth；Three timely and effective can not be blocked after turning one's coat.
The floor drain and existing other kinds of floor drain of 3 kinds of structures of illustrating above can not constantly ensure the air quality of interior
It is excellent, and after such as occurring in that substantial amounts of dirty or hair blocks floor drain, can not very easily be cleared up, some users
Hair is cleared up with clip, some users twist floor drain core with pliers, the user more having is convenient directly drain cover in order to clear up
Long-term throwing away puts aside, and floor drain core is only twisted the methods such as a button to reach the purpose of easy cleaning floor drain.Also in every day use
During hair or it is dirty can be dispersed in drain cover nearby or be blocked on floor drain cap surface, one is that have impact on lower water, two be
It is also inconvenient in cleaning.

Float is separably connected to the delivery port of housing；Lid is arranged at housing top, and with entering for being connected with housing cavity
Water hole；The float passage stretched out for float is provided with the middle part of lid.
The course of work of floor drain is summarized as follows：Under original state, float is connected to delivery port (the float seal residence of floor drain
The delivery port of leakage), during Xia Shui, the water body in floor drain is gradually assembled, and water body acts on the upward buoyancy of float gradually
Increase, when the upward buoyancy that water body acts on float is more than the gravity of float, float is gradually increasing, and now float is gradually remote
The delivery port of liftoff leakage, water body can be flowed out by delivery port.When the water body and the water body flowed out by delivery port that flow into floor drain
During in poised state, float is in released state all the time with the delivery port of floor drain, thus can ensure the normally lower water of floor drain.
When the flow of the water body for flowing into floor drain is tapered into, the buoyancy of the water body that float is subject to is not enough to overcome the gravity of float itself
When, float is gradually reduced up to the delivery port of closure floor drain, it is achieved thereby that the closure of floor drain, prevents under self gravitation effect,
The generation of peculiar smell reflux problem.
In addition, there is advantages below through type float floor drain：One is that the float passage can limit swinging for float
Amplitude so that float try one's best be maintained at vertical direction up and down motion.Two be set float passage after, it is highly constant in floor drain body
In the case of can be designed to the bigger float of buoyancy, or float can be allowed to float height higher, when float rises to necessarily
Height after, the lower water effect of floor drain equivalent to it is straight-through off the stocks.Three is the motion conditions that user can directly observe float,
When float floats it is difficult when because impurity for being gathered in floor drain body or hair etc. are too many, it is known that floor drain this clean up,
When float is static after drained water, by surface observation float it is static when state it is known that float blocks collector nozzle
Situation, as above uneven surface, or certain position has been higher by, illustrate that float is not blocked collector nozzle, it is necessary to clear up one
Lower floor drain, on the contrary explanation float has blocked collector nozzle, and such floor drain can allow user to be leaked down over the ground the closure at the mouth of a river
Situation is felt to trust, and is easily known that the working condition of floor drain, and four is the float when debris are too many in floor drain housing
Interim card or not floaty phenomenon, or crooked phenomenon are likely to occur, at this moment user can directly take out float, to floor drain body
After inside pouring a certain amount of water body, the particulate matter even heavier than water less than the debris of delivery port can just be directly discharged into sewer,
Greatly facilitate the process and efficiency of cleaning floor drain.Five is when displacement is very big, due to the height that float floats upwards
Without limitation, or even float can be with the lid of emersion to floor drain on, such that it is able to reach the effect of straight through drainage.Six is to work as
When needing to enter sewer with the more water of impurity, user easily can directly take out float, allow the impurity water body can be with
Unhinderedly faster enter sewer pipe.Seven is that float is moved so can very great Cheng due at least a part of in float passage
Downward frictional force that the reduction water body of degree is produced during decline to float or frictional force and water body are in float upper surface
Pressure so that the upward floating that float can be almost without hindrance, improves drainage speed.
In addition, upper and lower surface of the float passage through lid, float passage upper and lower surface do not have it is any block, can make
Float is floated no height limitation upwards, and floor drain can be allowed to discharge water level water higher, and user can be allowed directly to take out float,
Due to float at least a portion be deep into passage, when passage be designed to it is watertight in the case of, when water body is in not higher than passage
During upper space, water body will not give float downward frictional force during Xia Shui, float can be allowed to reach non-resistance and floated,
When passage design reticulates water leakage situation, upper channel can play a part of to intercept debris.
The invention of technical scheme 2, float passage top is additionally provided with protective cover, has between protective cover and float passage and lives
Dynamic space.Protective cover is used to avoid float mechanically damaged.Protective cover is detachably connected with lid can be according to user's
Selection is needed not use protective cover using protective cover or selection.There is activity space, the work between protective cover and float passage
Do not interfered by the mechanics of protective cover when ensure that float movement to peak in dynamic space.In addition, protective cover can also avoid floating
The blockage problem that son is pushed down and caused by external object.
The invention of technical scheme 3, the lower surface of lid is provided with limited impression, buoy upper energy during fluctuating
Limited impression is enough stretched into, limited impression can ensure that float is moved in vertical direction all the time, it is to avoid float is because of the width for swinging
The problem of the difficulty that playbacked caused by spending greatly, solves due to the float playback not tight problem of difficult caused delivery port closure.
The invention of technical scheme 4, the following table of lid faces away from the spacing enclosing that the direction of lid is set, and float is floating
Preceding buoy upper is embedded in enclosing with regard to some, and spacing enclosing one can be to ensure that float is vertical up and down in the range of enclosing
Direction is moved, and two can be that before ensureing float passage of the buoy upper in emersion lid, can be directed at lid channel outlet, protect
Card float by float channel outlet edge barrier, and will not be caused after a large amount of drainings, and float is unable to emersion lid upper surface, is caused
Prevent float from rising height higher, cause displacement to decline.Three is when lid is designed to such as abs or polyethylene lightweight material
During material, when lid passway is designed to the wire side or plane of stop, when big yield draining, float floats to lid plane
When upper, lid jack-up can be made float floating height higher by the buoyancy of float, can make draining faster.
The invention of technical scheme 5, float includes float main body and is arranged at float main body and for stretching into odour-proof floor drain
The delivery port that has of housing in function part；When the buoyancy that the water in floor drain housing acts on float can overcome the weight of float
During power, float float so that function part outer surface and delivery port between from sealing mated condition to released state change, water can
Flowed out by the delivery port of floor drain.When the buoyancy that the water in floor drain housing acts on float can overcome the gravity of float, float
Son float so that function part outer surface and delivery port between from sealing mated condition to released state change, water can be by floor drain
Delivery port outflow.The course of work of floor drain is summarized as follows：Under original state, float is connected to the delivery port of floor drain, and (float is close
Seal the delivery port of floor drain), during Xia Shui, the water body in floor drain is gradually assembled, and water body acts on the upward of float and floats
Power gradually increases, and when the upward buoyancy that water body acts on float is more than the gravity of float, float is gradually increasing, now float
The delivery port of floor drain is gradually distance from, water body can be flowed out by delivery port.When the water body for flowing into floor drain is flowed out with by delivery port
Water body when being in poised state, the delivery port of float and floor drain is in released state all the time, thus can ensure floor drain just
Water under often.When the flow of the water body for flowing into floor drain is tapered into, the buoyancy of the water body that float is subject to is not enough to overcome float itself
Gravity when, float be gradually reduced under self gravitation effect, until closure floor drain delivery port, it is achieved thereby that the envelope of floor drain
It is stifled, prevent the generation of peculiar smell reflux problem, thus, the float can effectively solve the problems, such as the peculiar smell reflux of floor drain.
The invention of technical scheme 6, there is provided four kinds of structure types of function part：
Form one, function part includes the first hemisphere, and first hemispheroidal at least a portion is used to stretch into delivery port.
Setting the first hemispheroidal reason is：One is that float may return to the center of collector nozzle after lower water terminates,
Ensure that the self gravitation of float, to amount of pressure under the maximum of the closed contact surfaces of collector nozzle, can prevent bigger anti-taste gas
Pressure, plays more preferable anti-odor effect；Two is because the hemisphere of function part is sphere, even if float is caused due to special circumstances
When float is crooked, due to hemispheroidal cross section or circle, the cross section of collector nozzle is also circular, the function part of such float
Hemisphere still can form good sealing effect with collector nozzle contact surface, gap will not be produced, preferably prevent down
Peculiar smell is upper anti-in waterpipe.Three is the buoyancy that hemisphere can increase some floats in lower water, make float it is easier on
Rise.
Form two, function part includes the first cone, and at least a portion of the first cone is used to stretch into delivery port；
The reason for setting the first cone be：When closure delivery port is needed, water outlet is stretched at the tip of the first cone
Mouthful, the crosscutting circular conical surface of the first cone is contacted with the inner wall edge of downcomer, it is achieved thereby that the closure function of floor drain, a side
Face, the part that the first cone stretches into downcomer is more, and float in the vertical direction is more stablized；On the other hand, the first circular cone
Body is floated up to during leaving downcomer completely from extreme lower position, and because cone is extend into downcomer, cone exists
Be in downcomer it is upper it is thick gradually under thin shape, when float rises, during cone leaves downcomer, lower water-carrying capacity is one
Individual ascending process, float will not be because of at the initial stage of rising, because lower water is excessive, (lower water is bigger, under downcomer during water
The siphon effect of generation is more obvious, and collector nozzle near surface is bigger to the suction of object) and float absorption in collector nozzle, float
Can be easier to realize floating in the presence of the first cone, (be also that float is completely disengaged from down when water reaches maximum instantly
During the mouth of a river) collector nozzle surface is also maximum to the suction of object, but because the effect float of cone has been floated to necessarily
Height, away from the maximum suction zone of collector nozzle near surface, such float would not be attracted near collector nozzle, cause
Interim card or the phenomenon by suction tightly in the case where collector nozzle causes to drip not, the meeting of cone bottom and water also during Xia Shui
Close contact, increases the buoyancy of float, and along with downcomer, water is smaller under the lower water initial stage, suction of the collector nozzle to float
Power is smaller, both collective effects, makes the rising that float can be quickly, and lower water-carrying capacity can reach in line effect, solve float
The bad problem of lower water effect that floor drain is present, is also the reason for current float floor drain can not be widely popularized.
Form three, function part includes the second hemisphere and the second cone；Second hemispheroidal plane and float main body phase
Connection, the second hemispheroidal sphere is connected with the portion wide of the second cone, wherein, the second hemispheroidal Breadth Maximum is more than
The width at the mouth of a river, the width of the Breadth Maximum less than delivery port of the second cone.The reason for setting the second cone be：One side
Face, the part that the second cone is all stretched into downcomer is more, and float in the vertical direction is more stablized；In addition, with reference to upper
The advantage of technical scheme 2 and technical scheme 3 is stated, one is the float hemisphere surface of function part and downcomer in the case of crooked
Gap will not be produced between contact sealing surface, two is that float is not in interim card or is adsorbed by collector nozzle during Xia Shui
Phenomenon.
Form four, function part includes the 3rd hemisphere, the first cylinder and the 3rd cone；3rd hemispheroidal plane with
Float main body is connected, and one end of the first cylinder is connected with the 3rd hemispheroidal curved surface, the other end of the first cylinder with
The portion wide of the 3rd cone is connected, wherein, width of the 3rd hemispheroidal Breadth Maximum more than delivery port.First cylinder and
Width of the Breadth Maximum of the 3rd cone less than delivery port.
The reason for setting the first cylinder be：Float is increased at the rising initial stage, collector nozzle is to float minimum suction
Highly, such as, rise 1 millimeter height suction be with the suction of the height for rising to 3 millimeters as, so can be under
Mouth of a river near surface produces what float before maximum suction can be earlier to rise to certain height to float, can depart from faster
Maximum suction of the collector nozzle to float.Can float be not in interim card or be attracted on lower water in any case with safer guarantee
The phenomenon of mouth, it is ensured that draining is unobstructed under any circumstance.The inventive structure of other technical scheme 4 has hemisphere, cylinder
Body, cone three acts on the advantage of float and the perfect adaptation of the whole body.Water effect leak down not in the ground for solving Floater Structure
Good problem, road has been paved to be widely popularized float floor drain.
The invention of technical scheme 7, elongated portion, elongated portion and work(have been extended downwardly in the side near function part of function part
There is gap between energy portion.Set elongated portion the reason for be：On the one hand elongated portion can be protected to the function part of float,
On the other hand, elongated portion stretches into the water seal position of housing, reaches the effect of water seal anti-odor, in addition, in the less feelings of lower water
Under condition, heavier particulate matter can sink to the bottom at water seal position, and lighter drift can be blocked in the outside of float, keep away
The stop in the water inlet of downcomer such as particulate matter, floating object is exempted from, the function part of such float can preferably close lower water
Mouthful.Normal anti-odor, the back-water-proof function of floor drain are ensure that, current float floor drain is solved and is often closed that collector nozzle is not tight to be showed
As.
The invention of technical scheme 8, housing is provided with from the lowermost end of housing to the inner chamber of housing away from one end of lid
The downcomer for setting is protruded, elongated portion can extend between downcomer and inner walls.Elongated portion is stretched into downcomer and housing
Sealing structure for water is formed after between wall, water seal can effectively prevent the generation of anti-taste problem.
The invention of technical scheme 9, the also screen pack including being arranged between float and lid.Screen pack can retain hair
Hair, it is to avoid hair is directly entered the floor drain that floor drain causes and blocks or be directly entered the sewer from blocking that sewer pipe is caused.Or
Person, also including the upper end open for blocking housing being detachably connected with inner walls that is arranged between float and lid
Closure.When leak is needed, closure is taken out, floor drain is realized normal water drainage function, when without using floor drain, will be close
Capping blocks the opening of floor drain completely, can thoroughly solve the problems, such as the peculiar smell reflux and back-water-proof of floor drain.In addition, not
If it find that there is the generation of phenomenon of turning one's coat during using closure, can thoroughly be prevented by closure timely seal floor drain
Continue to turn one's coat.Or, the also check (non-return) valve including being arranged at below float.When check (non-return) valve is subject to enough hydraulic pressure, check (non-return) valve is beaten
Open, fluid can flow into sewer pipe by check (non-return) valve, when the hydraulic pressure that check (non-return) valve is subject to is not enough, check (non-return) valve remains closed shape
State.Check (non-return) valve may be considered the one-level defence of the odour-proof floor drain, different in sewer pipe when check (non-return) valve is in closure state
Taste gas or will flow to floor drain body turn one's coat cannot by blade enter check (non-return) valve inner chamber, it is achieved thereby that isolation peculiar smell
The function of gas and back-water-proof.
At least one of the invention of technical scheme 10, lid, housing or float are made of clear material.Set transparent
The reason for material is：The bright-coloured ornaments such as little Hua, the small grass of vacation, small fish are such as placed inside float, because float is
Transparent, these ornaments are from outside, it is clear that landscaping effect can be played, and ornament is sealed in float
Inside so will not be dirty, it is always neat and tidy.Floor drain is set also to turn into the bright spot in family.

The course of work of floor drain is summarized as follows：Under original state, float is connected to delivery port (the float seal residence of floor drain
The delivery port of leakage), during Xia Shui, the water body in floor drain is gradually assembled, and water body acts on the upward buoyancy of float gradually
Increase, when the upward buoyancy that water body acts on float is more than the gravity of float, float is gradually increasing, and now float is gradually remote
The delivery port of liftoff leakage, water body can be flowed out by delivery port.When the water body and the water body flowed out by delivery port that flow into floor drain
During in poised state, float is in released state all the time with the delivery port of floor drain, thus can ensure the normally lower water of floor drain.
When the flow of the water body for flowing into floor drain is tapered into, the buoyancy of the water body that float is subject to is not enough to overcome the gravity of float itself
When, float is gradually reduced up to the delivery port of closure floor drain, it is achieved thereby that the closure of floor drain, prevents under self gravitation effect,
The generation of peculiar smell reflux problem.
In addition, there is advantages below through type float floor drain：One is that the float passage can limit swinging for float
Amplitude so that float try one's best be maintained at vertical direction up and down motion.Two be set float passage after, it is highly constant in floor drain body
In the case of can be designed to the bigger float of buoyancy, or float can be allowed to float height higher, when float rises to necessarily
Height after, the lower water effect of floor drain equivalent to it is straight-through off the stocks.Three is the motion conditions that user can directly observe float,
When float floats it is difficult when because impurity for being gathered in floor drain body or hair etc. are too many, it is known that floor drain this clean up,
When float is static after drained water, by surface observation float it is static when state it is known that float blocks collector nozzle
Situation, as above uneven surface, or certain position has been higher by, illustrate that float is not blocked collector nozzle, it is necessary to clear up one
Lower floor drain, on the contrary explanation float has blocked collector nozzle, and such floor drain can allow user to be leaked down over the ground the closure at the mouth of a river
Situation is felt to trust, and is easily known that the working condition of floor drain, and four is the float when debris are too many in floor drain housing
Interim card or not floaty phenomenon, or crooked phenomenon are likely to occur, at this moment user can directly take out float, to floor drain body
After inside pouring a certain amount of water body, the particulate matter even heavier than water less than the debris of delivery port can just be directly discharged into sewer,
Greatly facilitate the process and efficiency of cleaning floor drain.Five is when displacement is very big, due to the height that float floats upwards
Without limitation, or even float can be with the lid of emersion to floor drain on, such that it is able to reach the effect of straight through drainage.Six is to work as
When needing to enter sewer with the more water of impurity, user easily can directly take out float, allow the impurity water body can be with
Unhinderedly faster enter sewer pipe.Seven is that float is moved so can very great Cheng due at least a part of in float passage
Downward frictional force that the reduction water body of degree is produced during decline to float or frictional force and water body are in float upper surface
Pressure so that the upward floating that float can be almost without hindrance, improves drainage speed.
In addition, upper and lower surface of the float passage through lid, float passage upper and lower surface do not have it is any block, can make
Float is floated no height limitation upwards, and floor drain can be allowed to discharge water level water higher, and user can be allowed directly to take out float,
Due to float at least a portion be deep into passage, when passage be designed to it is watertight in the case of, when water body is in not higher than passage
During upper space, water body will not give float downward frictional force during Xia Shui, float can be allowed to reach non-resistance and floated,
When passage design reticulates water leakage situation, upper channel can play a part of to intercept debris.
In the alternative of the present embodiment, float passage top is additionally provided with protective cover, between protective cover and float passage
With activity space.Protective cover is used to avoid float mechanically damaged.Protective cover and lid are detachably connected can be according to making
Select not use protective cover using protective cover or selection the need for user.Have activity empty between protective cover and float passage

Face, the part that the first cone stretches into downcomer is more, and float in the vertical direction is more stablized；On the other hand, the first circular cone
Body is floated up to during leaving downcomer completely from extreme lower position, and because cone is extend into downcomer, cone exists
Be in downcomer it is upper it is thick gradually under thin shape, when float rises, during cone leaves downcomer, lower water-carrying capacity is one
Individual ascending process, float will not be because of at the initial stage of rising, because lower water is excessive, (lower water is bigger, under downcomer during water
The siphon effect of generation is more obvious, and collector nozzle near surface is bigger to the suction of object) and float absorption in collector nozzle, float
Can be easier to realize floating in the presence of the first cone, (be also that float is completely disengaged from down when water reaches maximum instantly
During the mouth of a river) collector nozzle surface is also maximum to the suction of object, but because the effect float of cone has been floated to necessarily
Height, away from the maximum suction zone of collector nozzle near surface, such float would not be attracted near collector nozzle, cause
Interim card or the phenomenon by suction tightly in the case where collector nozzle causes to drip not, the meeting of cone bottom and water also during Xia Shui
Close contact, increases the buoyancy of float, and along with downcomer, water is smaller under the lower water initial stage, suction of the collector nozzle to float
Power is smaller, both collective effects, makes the rising that float can be quickly, and lower water-carrying capacity can reach in line effect, solve float

The portion wide of the 3rd cone is connected, wherein, width of the 3rd hemispheroidal Breadth Maximum more than delivery port.First cylinder and
Width of the Breadth Maximum of the 3rd cone less than delivery port.
The reason for setting the first cylinder be：Float is increased at the rising initial stage, collector nozzle is to float minimum suction
Highly, such as, rise 1 millimeter height suction be with the suction of the height for rising to 3 millimeters as, so can be under
Mouth of a river near surface produces what float before maximum suction can be earlier to rise to certain height to float, can depart from faster
Maximum suction of the collector nozzle to float.Can float be not in interim card or be attracted on lower water in any case with safer guarantee
The phenomenon of mouth, it is ensured that draining is unobstructed under any circumstance.The inventive structure of other technical scheme 4 has hemisphere, cylinder
Body, cone three acts on the advantage of float and the perfect adaptation of the whole body.Water effect leak down not in the ground for solving Floater Structure
