In practical use, the lower end of the drainer main body 5 is often required to be connected with pipelines with different pipe diameters, and good sealing performance is ensured when the pipelines are connected. The technical scheme can achieve the two effects while being good.
Preferably, a bracket 15 is arranged inside the drainer main body 5;
the sealing element 9 comprises a rod part 143 and a sealing part 14 fixed at the upper end of the rod part 143;
the rod 143 is inserted into the bracket 15, a reset mechanism is arranged between the sealing element 9 and the bracket 15, the reset mechanism comprises a first magnetic element 16 and a second magnetic element 13 which are respectively connected into the bracket 15 and the rod 143, and the sealing element 9 moves upwards and seals the water flow channel under the action of magnetic force between the first magnetic element 16 and the second magnetic element 13.
This technical scheme specifically discloses a seal structure for pipeline. The sealing element 9 is a part of umbrella-shaped structure, and when the sealing element 9 rises and abuts against the inner side of the drainer main body 5, the functions of deodorization and water flow channel closing or conducting are realized.
Such technical scheme simple structure design is convenient, when this product is used to needs, guarantees that this product can lead to water, can play sealed deodorant effect when not using. And the whole process can be realized without manpower.

Through external a locking cap 8, just can adapt to the pipeline of different pipe diameters through the external diameter that changes locking cap 8. The lower pipe sealing ring 7 is sleeved at the outer end of the locking cap 8, the lower pipe sealing ring 7 is deformed by the squeezing action of the lower water device main body 5 on the lower pipe sealing ring 7, and the connection between the pipeline and the locking cap 8 can be tighter, so that the effect of better sealing effect compared with the prior art is achieved. The step ring 82 serves to provide a positioning position for the lower tube sealing ring 7, because in practical use, the locking cap 8 is pushed up against the lower tube sealing ring 7 from below, and thus has a positioning position.
The outer end of the locking cap 8 is sleeved with a lower pipe sealing ring 7, and the outer diameter of the lower pipe sealing ring 7 is larger than that of the lower end of the lower water device main body 5. Such a design is to facilitate insertion of the external conduit.

It is common to form some anti-slip grooves in the outer edge of the lower end of the locking cap 8 for more stable rotation. However, even such a design is not labor-saving enough.
Therefore, an outer connecting sleeve 6 is connected to the outer end of the drainer main body 5 in a threaded mode, and the outer connecting sleeve 6 is enabled to extrude the lower pipe sealing ring 7 in a gradually rotating mode under the action of threads. This allows the lower tube seal 7 to deform and thereby increase sealing performance.

This technical scheme specifically discloses a scheme that can make low tube sealing washer 7 enlarge. The deformation is conventionally done by extrusion, but is here described as being effected by a chamfer 62, i.e. by a wedge-shaped cross-section. Such an approach is more labor-saving and convenient.
Preferably, the distance between two adjacent annular sleeves 61 is greater than the wall thickness of the circumscribed pipe to be fitted. The technical scheme specifically discloses a structural form of the external sleeve 6. In practical use, application scenarios with a relatively large range of pipe diameter variation can be encountered. If the external sleeve 6 is used alone or the locking cap 8 is used alone, the situation beyond the application range occurs. Therefore, in order to increase the adaptation range of the external pipe fitting, the external sleeve 6 is designed to be in a multi-layer mode in the technical scheme.
