Description
Technical field
The present invention relates to a kind of trap, more particularly, to it is a kind of with can reverse-filling and water seal be difficult dry water
It is curved.
Background technology
Trap is the conventional drainage element that drainage system is used in building field, and the purposes of existing trap is to use
The anti-waste gas of deodorization in the drainage system of water appliance, earliest structure is to form water seal with water bend pipe under S type water consumption device wares
Structure, is used to completely cut off waste gas and foul smell in drainage pipeline and is got in by drainage pipeline, while also intercepted cockroach etc. leading to
Drainage pipeline is crossed to get in.
Existing trap has the structures such as S types, p-type, appositional pattern, is suitable for different spaces（Referring to Fig. 6）, however, these
There is following defect in trap：
(1) without anti-dry effect：Water seal is open architecture, if the water appliance for some time on trap is disabled, trap is just
Water seal can be lost because water volatilization reduces even dry, lead to not play a part of to intercept Anti-bad-smell anti-insect（Referring to Fig. 7）；
(2) trap easily deposits dirty dirt, influences drainage effect：The water structure that trap has easy dirt deposits in itself,
Rubbish from cooking oiliness plus China is big, is easily attached to tube wall, and its thicker viscosity of accumulation is higher, also easily adheres to chip class rubbish
Rubbish, make pipeline get over contracting it is smaller so that influence drainage effect worse and worse until block, therefore, existing trap generally needs
Timing looks for workman to dredge maintenance；
(3) anti-effect returning water performance is not had：The one-way valve structures that existing trap structure pours in down a chimney without anti-effect returning water, if because heavy rain, hair are big
The reasons such as water cause if the sewer water level trap water level relatively low higher than physical features is in, and have and return the phenomenon hair that water pours in down a chimney
It is raw.
To solve the above problems, the present inventor provides one kind in Chinese utility model patent CN201320795768.3
Long-acting totally-enclosed water-sealing stinking-proof trap, it includes trap main body, and trap main body includes housing and bottom, trap master
Sealing structure for water is set in vivo, and the sealing structure for water is nested the vertical water annulus that constitutes by water seal outer sleeve and water seal inner sleeve and is formed,
Water seal outer sleeve is arranged on the bottom surface of bottom, and water seal inner sleeve upper limb is connected with case top, in the lower end of water seal inner sleeve and bottom
Bottom surface between a protection float with air cavity is set in space, the protection float main body be an intermediate projections periphery then with water
The card that the internal diameter of overcoat is adapted is sealed, card is peripherally distributed several balance pipes, its intermediate raised portion is air cavity, projection exists
In water seal inner sleeve, protection float is used to float using water buoyancy the lower port for closing water seal inner sleeve, meanwhile, above water seal outer sleeve
The one annular water seal panel being placed on water seal outer wall of inside race is set, the top of water seal outer sleeve is covered in, can the vertical ring of unidirectional blocking
The upper port of shape water channel, it can hold up open upper end mouthful, upper end is closed by self-weight reset during without draining in draining by current
Mouthful, twice enclosuring structure is formed together with protection float, can more muchly retain water body and bottom in vertical water annulus
Portion's water body, reaches the purpose of permanent water seal, while can prevent from pouring in down a chimney.The present inventor is follow-up and in CN201420756264.5
There is provided the improved long-acting totally-enclosed water-sealing stinking-proof trap of another kind, different from above-mentioned trap is that it is with spring
Kickboard instead of protection float, and water seal inner sleeve lower port, the bullet are closed to ensure that protection float can float all the time when without draining
Spring kickboard includes sheet kickboard and spring, and spring is located between bottom bottom surface and kickboard, and unidirectionally seals vertical water annulus
The water seal panel of upper port forms two road enclosuring structures together, muchly to retain the water body in vertical water annulus.
Although the trap of the above two sealing structure for water of the present inventor's research and development all realizes water seal resistance and reverse-filling work(
Can, and one one-way enclosed type vertical annular water seal is provided with, volatilized with the water in preventing water from sealing so that even if trap
Prolonged stoppage is used, and water seal is not all allowed volatile dry, can play the effectiveness of water seal.But, because two traps are all used
The Floater Structure that can be fluctuated closes the lower port of water seal inner sleeve, and this Floater Structure brings problems with：
1. be easy to block, lower water speed it is slow：It is easy to leak into float underlying space by silt, it is difficult to discharge and deposit wherein,
In the course of time the floating stroke of float is caused to reduce even 0.
Due to most of houses all can advanced luggage repair, then come into operation again, cleaning finishing scene when be often difficult to keep away
Have a large amount of silts with exempting from can enter sewer by trap, this above two trap patented technology is difficult to avoid that
After having fitted up, the float distance of run of trap is just significantly reduced, and causes trap to make it difficult for somewhat larger swill to pass through,
Easily block, lower water speed is always very slow.
2. float be difficult to persistently keep fluctuate it is smooth：Because float needs to be adapted to so as to steady with the cylindrical wall of bottom
Fluctuate and carry out the closing of vertical water channel lower port, float gabarit is smaller with the gap of bottom cylindrical wall, such as kitchen
During basin, a large amount of greasy dirts are readily adsorbed on the piece surface of trap, and the greasy dirt on attachment feature surface can be more over time
Come more sticky, so as to float can be influenceed successfully to fluctuate, if dry weather or disabling basin for some time, float is also
Cannot be moved during bottom can be fixedly arranged at because of the solidification of the greasy dirt on surface, cause float to fail.
3. closing water seal is easily failed：Because above-mentioned 2 problems can all cause float to lose effectiveness, once and float loses
Effect, then the lower sealing of closed water seal cannot just be closed with float, and enclosed water seal is formed so as to lead to not, and lose length
Phase keeps the effectiveness of water seal.
The content of the invention
An object of the present invention aim to provide it is a kind of with can reverse-filling and water seal be difficult dry trap, the water
