It is connected to inside water tank 22.
The conduit 20 is hose.
It is used between first vertical tube 15 and water tank 16 and connection is welded and fixed.
The water tank 16 is consistent with the placing height of cistern 22, and the height of cistern 22 is than water tank 16
Height want high 5-10cm.
The filter vat 6, set bucket 11 and water tank 16 are made of stainless steel material.
Working principle: in the use of the present invention, as shown in Figure 1, connecting tube 4 to be first embedded in the T-type mounting hole 2 of hand washing sink 1
Interior, for excluding to generate during washing one's face and rinsing one's mouth sewage, when then tightening fixture nut 5, so that retaining ring 3 is embedded in T-type mounting hole 2
Blind hole in, between retaining ring 3 and fixture nut 5 tightly clamping hand washing sink 12 top and bottom of T-type mounting hole, thus retaining ring
3 with fixture nut 5 on sealing ring 27 and the first sealing ring 28 respectively with 2 top and bottom of T-type mounting hole in lower pond 1 seal
The case where being bonded, effectively preventing leak generation.Then two fixed blocks 17 on water tank 16 are passed through two respectively again
Screw 18 is fixedly connected with metope, thus achieve the purpose that fixed water tank 16, in this way when people wash one's face and rinse one's mouth in hand washing sink 1,
Generated sewage can be flowed into filter vat 6 by connecting tube 4, in this process, due to the inclination of 4 Internal baffle 24 of connecting tube
Setting, the sewage flowed into connecting tube 4 can be pooled to 24 bottom end of baffle and 4 inner wall intersection of connecting tube, in this way since sewage converges
The weight baffle 24 integrated can be rotated clockwise with axis 26 as axle center, thus the rubber ring 29 on baffle 24 and 4 inner wall of connecting tube point
It will be flowed into filter vat 6 by connecting tube 4 from, such sewage, after the sewage in hand washing sink 1 is drained from connecting tube 4,
Due to the setting of clump weight 30, baffle 24 can return original position again, thus the rubber ring 29 on baffle 24 again with 4 inner wall of connecting tube
Fitting, such baffle 21 can effectively obstruct the peculiar smell from sewer pipe reflux.When sewage flows into filter vat 6, due to
The setting of 6 filtering net 10 of filter vat, filter screen 10 can effectively retain the bulky grain rubbish adulterated in sewage, effective anti-
The case where rubbish enters sewer and causes blocking in sewage generation is stopped, and has been passed through on filter vat 6 by filtered sewage
Through-hole 9 flows in set bucket 11, passes through vertical tube 12 again into the sewage in set bucket 11 and the first vertical tube 15 flows into water tank 16,
During this, when needing to clear up when the rubbish of 6 filtering net 10 of filter vat retention is excessive, unscrew upper shield 8 and the respectively first
One upper shield 13, then grip bucket 11 are taken out between connecting tube 4 and the first vertical tube 15, then to rubbish in the filter vat 6 in set bucket 11
Rubbish is cleared up, and has effectively achieved the purpose that rubbish in convenient and fast cleaning filter vat 6 in this way, due to the second sealing ring 31 and
The setting of three sealing rings 23 is tightly connected between filter vat 6 and connecting tube 4 by the second sealing ring 31, and vertical tube 12 and first erects
It is tightly connected between pipe 15 by third sealing ring 23.It is arranged after sewage flows into water tank 16 by its side wall bottom end
Conduit 20 flows into cistern 22, and utilizes the water entered in cistern 22 that can rinse closestool, to reach dirt of washing one's face and rinsing one's mouth
The purpose of water Collection utilization, since water tank 16 is consistent with the placing height of cistern 22, and the height of cistern 22
It is 5-10cm higher than the height of water tank 16, so the water level in water tank 16 is forever consistent with the water level in cistern 22,
And it can not be overflowed from cistern 22, when the water level in water tank 16 reaches drainpipe 19 and 16 connectivity part of water tank,
It can be gone out again from the sewage that the first vertical tube 15 enters in water tank 16 by 19 overflow of drainpipe, since 19 other end of drainpipe is straight
Lead to sewer in succession, so that overflowing sewage out of water tank 16 will be discharged into sewer by drainpipe 19.
The basic principles, main features and advantages of the invention have been shown and described above.The technical staff of the industry should
Understand, the present invention is not limited to the above embodiments, and the above embodiments and description only describe originals of the invention
Reason, without departing from the spirit and scope of the present invention, various changes and improvements may be made to the invention, these changes and improvements
It all fall within the protetion scope of the claimed invention.The claimed scope of the invention is by appended claims and its equivalent circle
It is fixed.
