Description

TECHNICAL FIELD

[0002] The sewer is commonly used in bathroom equipment, and is installed at the sewer outlet of a wash basin or the like. The original sewer does not generally have a filter device, and cannot filter the water discharged into a sewer, which can easily cause the sewer to be blocked. Some existing sewers are provided with a filter device, but the filter device is not easy to remove and is inconvenient to clean.

[0003] For example, a barrier-free installed deodorizing sewer disclosed in Chinese Utility Model No. CN221399222U includes a sewer cup body and a sewer main body. The sewer cup body is detachably connected to the upper end opening of the sewer main body and has a water outlet on the lower side wall. The sewer main body is provided with a water outlet pipe on one side and a drain opening for connecting the water outlet pipe and the sewer main body on the side wall. A water baffle is arranged on the inner wall of the water outlet pipe. A drain height difference is arranged between the water baffle and the drain opening. A anti-blocking basket is arranged on the outer wall of the elastic core. The outer wall of the anti-blocking basket is matched with the inner wall of the sewer cup body and is provided with a plurality of annular grooves. A sealing ring is arranged in the annular groove.

[0004] When installed, the anti-blocking basket is in interference fit with the inner wall of the sewer cup body to achieve fixed and sealed installation. Since the sealing ring is arranged in the annular groove, when the sewer is pulled upward or pressed downward, the friction force generated between the sealing ring and the inner wall of the sewer cup body due to the interference fit causes resistance, and a large force is required to achieve the disassembly and assembly of the sewer, thereby making the disassembly and assembly inconvenient. SUMMARY

[0005] The utility model aims to provide a sewer with a movable sealing ring, which solves the problem of inconvenient disassembly and assembly by movably arranging the sealing ring.

[0006] The utility model is achieved in the following manner: a sewer with a movable sealing ring includes a water sealing cover. The lower end of the water sealing cover is connected to an elastic core. A filter basket is installed on the outer periphery of the lower end of the elastic core. A plurality of water passing holes are formed in the lower end surface of the filter basket. A shielding part is formed between adjacent two water passing holes. An annular recessed part is formed on the outer periphery of the filter basket. A sealing ring is movably arranged on the outer periphery of the annular recessed part. A lower limiting part is formed on the lower side of the annular recessed part. An upper limiting part is formed on the upper side of the annular recessed part.

[0007] Preferably, the lower end of the filter basket is formed with an annular connecting part. The shielding part is connected between the outer periphery of the annular connecting part and the filter basket. An internal thread is formed on the inner periphery of the annular connecting part. An external thread matched with the internal thread is formed on the outer periphery of the lower end of the elastic core.

[0008] Preferably, a plurality of arrow-shaped side exhaust holes are arranged in the annular recess.

[0009] Preferably, an annular groove is formed in the upper limiting portion, and an upper sealing ring is arranged in the annular groove.

[0010] Preferably, a sealing connecting portion is formed at the lower end of the water sealing cover, and a second sealing ring is arranged at the outer periphery of the sealing connecting portion.

[0011] Compared with the prior art, the utility model has the advantages of:

[0012] The utility model discloses a sealing ring one is set up movably, when the process of actually disassembling the water closet is in, when the water closet is pulled out upward or is pressed into the water closet downward, the frictional force that the sealing ring one and the inner wall surface of the water cup body produce because of interference fit changes from the sliding friction of the prior art into the rolling friction, and the frictional force is much smaller, so when disassembling, it is also more labor saving, convenient, and the anti -block basket realizes fixed sealing installation through the interference fit of the sealing ring one and the inner wall surface of the water cup body, and has no influence to use.
