Description

Technical Field

[0001] This application relates to the field of drainage pipes, and more particularly to a water trap. Background Technology

[0002] Water traps are key components of building drainage systems. Through an internal water seal, they effectively prevent odors, germs, and insects from entering the room, thus ensuring air quality and occupant health.

[0003] During the use of water traps, hair and food scraps from washbasins and kitchen sinks can easily accumulate at the bend of the water trap with the water flow, causing pipe blockage. This requires a professional plumber to disassemble the drain pipes for cleaning, thus increasing the cost of using the water trap. Summary of the Invention

[0004] To address the issue of high usage costs associated with water traps, this application provides a water trap.

[0005] This application provides a water trap, which adopts the following technical solution: A water trap includes an arc-shaped pipe, an inlet pipe, an outlet pipe, a filter cylinder, and at least two fixing components. The at least two fixing components are connected one-to-one to the two ends of the arc-shaped pipe along its arc direction. One end of the inlet pipe is connected to a drain pipe, and the other end of the inlet pipe is detachably connected to the fixing components. One end of the outlet pipe is connected to a sewer, and the other end of the outlet pipe is detachably connected to the fixing components. The filter cylinder is connected to the inner wall of the arc-shaped pipe facing the inlet pipe. Water in the inlet pipe is filtered by the filter cylinder and then enters the inner cavity of the arc-shaped pipe.

[0006] By adopting the above technical solution, when using the water trap, the inlet and outlet pipes are connected to two fixed components one-to-one. The end of the inlet pipe away from the fixed component is connected to the end of the drain pipe, and the end of the outlet pipe away from the fixed component is connected to the end of the sewer. The filter cartridge is connected to the inner wall of the arc-shaped pipe facing the inlet pipe. Water in the drain pipe enters the inner cavity of the arc-shaped pipe after being filtered through the filter cartridge. When the inner cavity of the filter cartridge becomes clogged with impurities, the user only needs to remove the arc-shaped pipe from the inlet and outlet pipes through the fixed components. The impurities accumulate on the inner wall of the filter cartridge facing the inlet pipe, and the user only needs to clean the inner wall of the filter cartridge. This improves the cleaning efficiency of the water trap and eliminates the need for professional plumbers to disassemble the drain pipe for cleaning, thereby reducing the cost of using the water trap.

[0007] Optionally, the fixing component includes a fixing ring, a positioning ring, and a locking ring. The inner ring of the positioning ring is coaxially connected to the outer ring of the locking ring, and the outer ring of the positioning ring is coaxially connected to the inner ring of the fixing ring. The length of the fixing ring along its axial direction is greater than the length of the locking ring along its axial direction, and the length of the locking ring along its axial direction is greater than the length of the positioning ring along its axial direction. The outer circumferential surface of the arc-shaped tube is coaxially provided with a positioning cavity for the positioning ring to be embedded in. The inner wall of the positioning cavity is coaxially provided with a locking groove for the locking ring to be embedded in. The inner ring of the fixing ring is coaxially provided with a water inlet pipe or a water outlet pipe. The inner ring wall of the fixing ring facing the water inlet pipe or the water outlet pipe is provided with a first threaded groove. The outer circumferential surfaces of the water inlet pipe and the water outlet pipe are both provided with a second threaded groove that matches the first threaded groove.

[0008] By adopting the above technical solution, when the end of the inlet pipe or the end of the outlet pipe is embedded in the inner ring of the fixing ring, the fixing ring is turned, and the inner wall of the first thread groove engages with the second thread groove. The end of the fixing ring away from the positioning ring is screwed and fixed to the end of the inlet pipe or the end of the outlet pipe, realizing the detachable connection between the arc-shaped pipe and the inlet and outlet pipes. At the same time, the positioning ring rotates on the inner wall of the positioning cavity, and the locking ring rotates on the inner wall of the locking groove. The length of the locking ring in the axial direction is greater than the length of the positioning ring in the axial direction, making it difficult for the positioning ring to detach from the arc-shaped pipe. The fixing ring is rotatably connected to the outer circumference of the arc-shaped pipe through the positioning ring and the locking ring, thereby ensuring the stability of the connection between the inlet pipe and the arc-shaped pipe.

[0009] Optionally, the fixing component further includes a sealing ring bladder, and the outer circumferential surface of the arc-shaped tube is coaxially provided with a sealing cavity for the inner ring of the sealing ring bladder to be embedded, and the inner wall of the fixing ring is coaxially provided with a sealing groove for the outer ring of the sealing ring bladder to be embedded, and the inner wall of the sealing cavity and the inner wall of the sealing groove clamp the two sides of the sealing ring bladder to form a seal.

[0010] By adopting the above technical solution, the inner wall of the sealing ring bladder abuts against the inner wall of the sealing cavity to form a seal, and the outer wall of the sealing ring bladder abuts against the inner wall of the sealing groove to form a seal. This makes it difficult for the liquid in the arc-shaped pipe to overflow from the abutment between the inner wall of the fixed ring and the outer circumference of the arc-shaped pipe, thereby improving the sealing performance of the water trap and ensuring the stability of the water trap drainage.

[0011] Optionally, the filter cartridge is slidably connected to the inner wall of the arc-shaped tube. The sliding direction of the filter cartridge is parallel to the axis of the fixing ring. A clamping assembly is connected between the fixing ring and the filter cartridge. The clamping assembly includes a clamping ring and an elastic element. The fixing ring has a clamping cavity coaxially opened on the inner wall of the filter cartridge for the clamping ring to slide. The sliding direction of the clamping ring is parallel to the sliding direction of the filter cartridge. The inner wall of the clamping ring is coaxially connected to the outer circumferential surface of the filter cartridge. One end of the elastic element is connected to the surface of the clamping ring in the elastic direction, and the other end is connected to the inner wall of the clamping cavity. The elastic element has the elastic force to drive the clamping ring away from the positioning ring, and the filter cartridge opening tends to protrude from the end face of the arc-shaped tube. When the fixing ring is coaxially sleeved on the outer circumferential surface of the water inlet pipe and screwed tight, the end face of the water inlet pipe and the end face of the arc-shaped tube clamp the two sides of the clamping ring in the axial direction to form a seal, and the filter cartridge opening is flush with the end face of the arc-shaped tube.

[0012] By adopting the above technical solution, the elastic element drives the clamping ring to slide away from the positioning ring along the inner wall of the clamping cavity, and the filter cylinder opening protrudes from the arc-shaped pipe surface. When the fixing ring is coaxially sleeved on the outer circumference of the water inlet pipe and screwed tight, the end face of the water inlet pipe and the end face of the arc-shaped pipe clamp the two ends of the clamping ring in the axial direction to form a seal. The filter cylinder opening is flush with the end face of the arc-shaped pipe, so that the liquid in the water inlet pipe is not easy to overflow from the clamping point of the water inlet pipe and the arc-shaped pipe, further improving the sealing performance of the water trap.

[0013] Optionally, the clamping assembly further includes a clamping piston, the end of which is connected to the surface of the clamping ring away from the elastic element. The inner wall of the clamping cavity is provided with an air passage for the clamping piston to slide. The sliding direction of the clamping piston is parallel to the axis of the fixed ring, and the air passage is connected to the inner cavity of the sealing ring bladder.

[0014] By adopting the above technical solution, when the fixing ring is coaxially sleeved on the outer circumference of the water inlet pipe and screwed on, the end face of the water inlet pipe abuts against the surface of the clamping ring and pushes the clamping ring to slide along the inner wall of the clamping cavity toward the direction close to the arc-shaped pipe. The end face of the water inlet pipe and the end face of the arc-shaped pipe clamp the two ends of the clamping ring in the axial direction to form a seal. At the same time, the clamping ring drives the clamping piston to slide toward the direction close to the positioning ring, pushing the air in the air passage into the inner cavity of the sealing ring bladder. The surface of the sealing ring bladder is pressurized and expands and abuts against the inner wall of the sealing cavity and the inner wall of the sealing groove, further improving the sealing stability between the fixing ring and the arc-shaped pipe.

[0015] Optionally, the fixing ring is connected to a sealing assembly, the sealing assembly including a sealing ring, and the end face of the fixing ring away from the positioning ring is coaxially provided with an installation cavity for the sealing ring to be embedded, the inner wall of the installation cavity and the outer peripheral surface of the water inlet pipe are respectively pressed against the two sides of the sealing ring to form a seal.

[0016] By adopting the above technical solution, the outer ring of the sealing ring is embedded in the installation cavity, and the outer ring of the sealing ring abuts against the inner wall of the installation cavity to form a seal. When the fixing ring is coaxially sleeved on the outer circumferential surface of the water inlet pipe and screwed on, the outer circumferential surface of the water inlet pipe and the inner wall of the installation cavity abut against both sides of the sealing ring to form a seal, making it difficult for the liquid in the water inlet pipe to overflow from the abutting point between the inner ring wall of the fixing ring and the outer circumferential surface of the water inlet pipe, thereby further improving the sealing performance of the water trap.

[0017] Optionally, the sealing assembly further includes a clamping ring and a connecting rod. The clamping ring is slidably connected to the inner wall of the mounting cavity. The sliding direction of the clamping ring is parallel to the axis of the fixed ring. The clamping ring is located on the side of the sealing ring away from the abutment ring. The end of the connecting rod is connected to the surface of the clamping ring facing the sealing ring. The surface of the sealing ring has a connecting hole for the connecting rod to pass through. The inner wall of the mounting cavity has a connecting cavity for the connecting rod to pass through. The connecting cavity connects the mounting cavity and the abutment cavity. The end of the connecting rod away from the clamping ring is connected to the surface of the abutment ring away from the abutment piston. When the end face of the water inlet pipe and the end face of the arc-shaped pipe clamp the two sides of the abutment ring one by one, the connecting rod pulls the clamping ring closer to the sealing ring. The ring surface of the clamping ring and the inner wall of the mounting cavity clamp the two sides of the sealing ring along the axial direction one by one, and the ring surface of the clamping ring is flush with the end face of the fixed ring.

[0018] By adopting the above technical solution, one end of the connecting rod is connected to the surface of the clamping ring, and the other end of the connecting rod is connected to the surface of the abutment ring. When the end face of the water inlet pipe and the end face of the arc-shaped pipe clamp the two sides of the abutment ring one by one, the connecting rod receives the power of the abutment ring and drives the clamping ring to slide along the inner wall of the installation cavity towards the sealing ring. The ring surface of the clamping ring and the inner wall of the installation cavity clamp the two sides of the sealing ring along the axial direction to form a seal. Moreover, the ring surface of the clamping ring is flush with the end face of the fixed ring. The operator can directly judge the connection relationship between the water inlet pipe and the arc-shaped pipe based on the flushness of the ring surface of the clamping ring and the end face of the fixed ring, thereby further improving the installation efficiency of the water trap.

[0019] Optionally, the sealing assembly further includes multiple limiting blocks. The inner ring wall of the compression ring is provided with multiple limiting grooves for the limiting blocks to slide. The sliding direction of the limiting blocks is perpendicular to the axis of the fixed ring. The outer circumferential surface of the water inlet pipe is provided with multiple limiting holes for the ends of the limiting blocks to be inserted. When the ring surface of the compression ring is flush with the end face of the fixed ring, the limiting grooves and limiting holes correspond one-to-one and are connected. The ends of the limiting blocks slide towards the limiting holes and are inserted. The outer circumferential surface of the limiting blocks abuts against the inner wall of the limiting holes and limits the rotation of the fixed ring.

[0020] By adopting the above technical solution, when the pressing ring surface is flush with the fixed ring end face, the limiting groove and the limiting hole correspond one by one and are connected, driving the end of the limiting block to slide and embed in the direction close to the limiting hole. The outer peripheral surface of the limiting block abuts against the inner wall of the limiting hole and limits the rotation of the fixed ring, making it difficult for the water inlet pipe to deflect in the inner ring wall of the fixed ring, and further improving the connection stability between the arc pipe and the water inlet pipe.

[0021] Optionally, the sealing assembly further includes a plurality of elastic elements II, each corresponding to a limiting block. One end of the elastic element II in the elastic direction is connected to the inner wall of the limiting groove, and the other end of the elastic element II in the elastic direction is connected to the surface of the limiting block. The elastic element II has the tendency to elastically drive the end of the limiting block to slide and embed itself in the direction close to the limiting hole.

[0022] By adopting the above technical solution, when the surface of the pressing ring and the surface of the fixing ring are flush, the limiting groove and the limiting hole correspond one by one and are connected. The elastic force of the second elastic element drives the end of the limiting block to slide and embed in the direction close to the limiting hole. The staff can also directly judge the tightening status of the fixing ring on the water inlet pipe based on the sound made when the limiting block is embedded in the limiting hole, further improving the installation efficiency of the water trap.

[0023] Optionally, the end of the limiting block that is embedded in the limiting hole is provided with a guide surface. The guide surface is in the shape of a circular arc protrusion. The guide surface can abut against the outer wall of the water inlet pipe and guide the end of the limiting block to be embedded in the limiting hole.

[0024] By adopting the above technical solution, the elastic element drives the limiting block to slide towards the water inlet pipe, and the guide surface abuts against the outer wall of the water inlet pipe. When the fixing ring is coaxially sleeved on the end of the water inlet pipe and tightened, the limiting groove and the limiting hole correspond one-to-one and are connected. At the same time, the guide surface abuts against the outer wall of the water inlet pipe and guides the end of the limiting block to be embedded in the limiting hole, reducing the wear between the limiting block and the water inlet pipe, thereby extending the service life of the water trap.

[0025] In summary, this application includes at least one of the following beneficial technical effects: With the installation of the arc-shaped pipe, inlet pipe, outlet pipe, filter cartridge, and fixing components, users only need to clean the inner wall of the filter cartridge, which improves the cleaning efficiency of the water trap and eliminates the need for professional plumbers to disassemble the drainage pipes for cleaning, thereby reducing the cost of using the water trap. The setting of the fixed ring, positioning ring and locking ring makes it difficult for the positioning ring to detach from the arc-shaped pipe, and realizes that the fixed ring is rotatably connected to the outer circumference of the arc-shaped pipe through the positioning ring and locking ring, thereby ensuring the stability of the connection between the water inlet pipe and the arc-shaped pipe. The sealing ring bladder prevents liquid inside the arc-shaped pipe from overflowing from the point where the inner wall of the fixing ring and the outer circumference of the arc-shaped pipe meet, thus improving the sealing performance of the water trap and ensuring the stability of the water trap's drainage.

[0029] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0030] This application discloses a water trap. (Refer to...) Figure 1 and Figure 2The water trap includes an arc-shaped pipe 1, an inlet pipe 2, an outlet pipe 3, a filter cylinder 4, and two fixing components 5. The arc-shaped pipe 1 includes an inlet section 11, an arc-shaped section 12, and an outlet section 13. In this embodiment, the inlet section 11 and the outlet section 13 are both straight pipes, and the arc-shaped section 12 is an arc-shaped pipe. One end of the arc-shaped section 12 is coaxially fixed to the end of the inlet section 11, and the other end of the arc-shaped section 12 is coaxially fixed to the end of the outlet section 13. The inner cavity of the arc-shaped section 12 connects the inner cavity of the inlet section 11 and the inner cavity of the outlet section 13. One fixing component 5 is connected to the end of the inlet section 11 away from the arc-shaped section 12 in the axial direction, and the other fixing component 5 is connected to the end of the outlet section 13 away from the arc-shaped section 12 in the axial direction. The fixing component 5 on the inlet section 11 can be detachably fixed to the end of the inlet pipe 2, and the fixing component 5 on the outlet section 13 can be detachably fixed. Fixed at the end of the outlet pipe 3, the end of the inlet pipe 2 away from the fixing component 5 is connected to the drainage pipe, and the end of the outlet pipe 3 away from the fixing component 5 is connected to the sewer. The filter cylinder 4 has multiple filter holes 41. The filter cylinder 4 is coaxially embedded in the inner wall of the inlet section 11 facing the inlet pipe 2. The outer wall of the filter cylinder 4 abuts against the inner wall of the inlet section 11 to form a positioning. The liquid in the drainage pipe enters the inner cavity of the arc-shaped pipe 1 after being filtered by the filter cylinder 4 through the inlet pipe 2. When the inner cavity of the filter cylinder 4 is full of impurities and becomes blocked, the user only needs to remove the arc-shaped pipe 1 from the inlet pipe 2 and the outlet pipe 3 through the fixing component 5. The impurities accumulate on the inner wall of the filter cylinder 4 facing the inlet pipe 2. The user only needs to clean the inner wall of the filter cylinder 4, which improves the cleaning efficiency of the water trap and eliminates the need for professional plumbers to disassemble the drainage pipe for cleaning, thereby reducing the cost of using the water trap.

[0031] Reference Figure 1 and Figure 2The fixing component 5 includes a fixing ring 51, a positioning ring 52, a locking ring 53, and a sealing ring sac 54. The inner wall of the positioning ring 52 is coaxially connected to the outer wall of the locking ring 53, and the outer wall of the positioning ring 52 is coaxially connected to the inner wall of the fixing ring 51. The length of the fixing ring 51 along its axis is greater than the length of the locking ring 53 along its axis, and the length of the locking ring 53 along its axis is greater than the length of the positioning ring 52 along its axis. The outer circumferential surfaces of the inlet section 11 and the outlet section 13 away from the arc-shaped section 12 are both coaxially provided with positioning cavities 111 for the positioning ring 52 to be inserted. The inner wall of the positioning cavity 111 is coaxially provided with a slot 112 for the locking ring 53 to be inserted. The inner ring of the fixing ring 51 is provided with a slot at the end of the inlet pipe 2 or... The end of the water outlet pipe 3 is coaxially embedded. The fixing ring 51 is coaxially provided with a threaded groove 511 facing the inner wall of the water inlet pipe 2 or the water outlet pipe 3. The outer circumferential surface of the water inlet pipe 2 and the outer circumferential surface of the water outlet pipe 3 are provided with a threaded groove 21 that matches the threaded groove 511. When the end of the water inlet pipe 2 and the end of the water outlet pipe 3 are embedded in the inner wall of the two fixing rings 51 respectively, the fixing ring 51 is turned, and the inner wall of the threaded groove 511 engages with the threaded groove 21. The fixing ring 51 is screwed and fixed to the end of the water inlet pipe 2 or the end of the water outlet pipe 3. At the same time, the positioning ring 52 rotates in the inner wall of the positioning cavity 111, and the surface of the locking ring 53 abuts against the inner wall of the locking groove 112 to realize the limitation of the fixing ring 51 on the arc-shaped pipe 1, so as to realize the detachable connection between the arc-shaped pipe 1 and the water inlet pipe 2 and the water outlet pipe 3.

[0032] Reference Figure 1 and Figure 2 The sealing ring bladder 54 can be made of rubber or silicone. In this embodiment, the sealing ring bladder 54 is made of rubber, which has a certain deformation capability. The outer circumferential surfaces of the inlet section 11 and the outlet section 13 are coaxially provided with sealing cavities 113 for the inner ring of the sealing ring bladder 54 to be embedded. The sealing cavity 113 is located on the side of the positioning cavity 111 away from the arc section 12. The inner wall of the fixing ring 51 is coaxially provided with a sealing groove 512 for the outer ring of the sealing ring bladder 54 to be embedded. The inner wall of the sealing cavity 113 and the inner wall of the sealing groove 512 clamp the two sides of the sealing ring bladder 54 to form a seal, so that the liquid in the arc tube 1 is not easy to overflow from the joint between the inner wall of the fixing ring 51 and the outer circumferential surface of the arc tube 1, thereby improving the sealing performance of the water trap and ensuring the stability of the water trap drainage.

[0033] Reference Figure 1 and Figure 2The axis of the filter cylinder 4 and the axis of the water inlet section 11 are parallel to each other. A clamping assembly 6 is connected between the fixing ring 51 and the filter cylinder 4. The clamping assembly 6 can drive the surface of the sealing ring 54 to press against the inner wall of the sealing groove 512 and the inner wall of the sealing cavity 113 to form a seal. The clamping assembly 6 includes a clamping ring 61, an elastic element 62 and a clamping piston 63. The fixing ring 51 is coaxially opened with a clamping cavity 513 for the clamping ring 61 to slide on the inner wall of the filter cylinder 4. The sliding direction of the clamping ring 61 is parallel to the axis of the fixing ring 51. The inner wall of the clamping ring 61 is coaxially fixed to the outer circumferential surface of the filter cylinder 4. When the clamping ring 61 slides on the inner wall of the clamping cavity 513, it drives the filter cylinder 4 to slide on the inner wall of the water inlet section 11.

[0034] Reference Figure 1 and Figure 2 The elastic element 62 can be a compression spring or a tension spring. In this embodiment, the elastic element 62 is a compression spring with a certain deformation capability. One end of the elastic element 62 in the direction of elastic force is connected to the surface of the retaining ring 61 facing the water inlet pipe 2, and the other end of the elastic element 62 in the direction of elastic force is connected to the inner wall of the retaining cavity 513. The elastic element 62 has the elastic force to drive the retaining ring 61 to slide away from the positioning ring 52, and the filter cylinder 4 has the tendency to protrude from the end face of the water inlet section 11.

[0035] Reference Figure 1 and Figure 2 The material of the pressing piston 63 can be rubber or silicone. In this embodiment, the material of the pressing piston 63 is rubber, which has a certain deformation capability. The number of pressing pistons 63 can be one, two or more. In this embodiment, the number of pressing pistons 63 is more than one. The ends of the multiple pressing pistons 63 are connected at intervals to the surface of the pressing ring 61 away from the elastic member 62. The inner wall of the pressing cavity 513 is provided with multiple air passages 514 for the pressing pistons 63 to slide. The sliding direction of the pressing pistons 63 is parallel to the axis of the fixed ring 51, and the multiple air passages 514 are all connected to the inner cavity of the sealing ring bladder 54.

[0036] Reference Figure 1 and Figure 2The end face of the clamping ring 61 protruding from the inner wall of the fixing ring 51 can abut against the end face of the water inlet pipe 2. When the fixing ring 51 is coaxially sleeved on the end of the water inlet pipe 2 and screwed on, the end face of the water inlet pipe 2 abuts against the ring surface of the clamping ring 61 and pushes the clamping ring 61 to move along the inner wall of the clamping cavity 513 towards the direction of the water inlet section 11. The end face of the water inlet section 11 and the end face of the water inlet pipe 2 clamp the two ends of the clamping ring 61 in the axial direction to form a seal. The opening of the filter cylinder 4 is flush with the end face of the water inlet section 11. At the same time, the clamping ring 61 drives the clamping piston 63 to slide towards the direction of the positioning ring 52, pushing the air in the air passage 514 into the inner cavity of the sealing ring bladder 54. The surface of the sealing ring bladder 54 is pressurized and expanded and abuts against the inner wall of the sealing cavity 113 and the inner wall of the sealing groove 512 to form a seal, further improving the sealing stability between the fixing ring 51 and the arc-shaped pipe 1.

[0037] Reference Figure 1 and Figure 2 A sealing component 7 is installed on the fixing ring 51 connected to the water inlet section 11. The sealing component 7 can abut against the inner wall of the fixing ring 51 and the outer circumferential surface of the water inlet pipe 2 to form a seal. The sealing component 7 includes a sealing ring 71, a pressing ring 72, a connecting rod 73, multiple limiting blocks 74 and multiple elastic elements 75. The material of the sealing ring 71 can be rubber or silicone. In this embodiment, the material of the sealing ring 71 is rubber, which has a certain deformation capability. The inner wall of the fixing ring 51, away from the positioning ring 52, is coaxially provided with an installation cavity 515 for the sealing ring 71 to be embedded. The inner wall of the installation cavity 515 and the outer circumferential surface of the water inlet pipe 2 abut against both sides of the sealing ring 71 to form a seal, so that the liquid in the water inlet pipe 2 is not easy to overflow from the abutment between the outer circumferential surface of the water inlet pipe 2 and the inner wall of the fixing ring 51, thereby improving the sealing performance of the water trap.

[0038] Reference Figure 1 and Figure 2 The clamping ring 72 is coaxially embedded in the mounting cavity 515 and slidably connected to the inner wall of the mounting cavity 515. The sliding direction of the clamping ring 72 is parallel to the axis of the fixing ring 51. The clamping ring 72 is located on the side of the sealing ring 71 away from the clamping ring 61. The number of connecting rods 73 can be one, two, or more. In this embodiment, the number of connecting rods 73 is more than one. The ends of the multiple connecting rods 73 are spaced around the axis of the clamping ring 72 and connected to the surface of the clamping ring 72 facing the sealing ring 71. The surface of the sealing ring 71 is provided with multiple... A connecting hole 711 is provided for the connecting rod 73 to pass through. The axis of the connecting hole 711 is parallel to the axis of the sealing ring 71. The connecting hole 711 passes through both sides of the sealing ring 71 along its own axis. Multiple connecting cavities 516 are provided at intervals on the inner wall of the mounting cavity 515 for the connecting rod 73 to pass through. The connecting cavity 516 connects the mounting cavity 515 and the pressing cavity 513. The end of the connecting rod 73 away from the pressing ring 72 in the length direction passes through the connecting hole 711 and the connecting cavity 516 and is fixed to the surface of the pressing ring 61 away from the pressing piston 63.

[0039] Reference Figure 1 and Figure 2 The inner wall of the clamping ring 72 is provided with multiple limiting grooves 721 for sliding of the limiting blocks 74 around the axis of the clamping ring 72. The sliding direction of the limiting blocks 74 is perpendicular to the axis of the clamping ring 72. The elastic element 75 corresponds to the limiting blocks 74 one by one. The elastic element 75 can be a compression spring or a tension spring. In this embodiment, the elastic element 75 is a compression spring and has a certain deformation capability. One end of the elastic element 75 in the elastic direction is connected to the inner wall of the limiting groove 721, and the other end of the elastic element 75 in the elastic direction is connected to the surface of the limiting block 74. The elastic element 75 has the elastic force to drive the limiting block 74 to slide in a direction closer to the axis of the clamping ring 72, and the end of the limiting block 74 protrudes from the inner wall of the clamping ring 72.

[0040] Reference Figure 1 and Figure 2 The outer circumference of the water inlet pipe 2 is provided with multiple limiting holes 22 for the end of the limiting block 74 to be inserted. The end of the limiting block 74 protruding from the inner wall of the clamping ring 72 is provided with a guide surface 741. The guide surface 741 is in the shape of a round arc protrusion. The guide surface 741 can abut against the outer wall of the water inlet pipe 2 and guide the end of the limiting block 74 to be inserted into the limiting hole 22, thereby reducing the wear between the limiting block 74 and the water inlet pipe 2 and extending the service life of the water trap.

[0041] Reference Figure 1 and Figure 2 When the end face of the water inlet section 11 and the end face of the water inlet pipe 2 are clamped one-to-one with the two ends of the clamping ring 61 in the axial direction to form a seal, the clamping ring 61 pulls the pressing ring 72 along the inner wall of the mounting cavity 515 towards the fixing ring 51 through the connecting rod 73. The ring surface of the pressing ring 72 and the inner wall of the mounting cavity 515 clamp the two sides of the sealing ring 71 in the axial direction to form a seal. The sealing ring 71 is deformed under pressure. The outer circumference of the water inlet pipe 2 and the inner wall of the mounting cavity 515 clamp the two sides of the sealing ring 71 to form a seal, further improving the sealing stability between the water inlet pipe 2 and the fixing ring 51.

[0042] Reference Figure 1 and Figure 2 Simultaneously, the face of the clamping ring 72 is flush with the end face of the fixing ring 51, the limiting groove 721 corresponds to and is connected to the limiting hole 22, and the elastic element 75 drives the end of the limiting block 74 to slide along the inner wall of the limiting groove 721 toward the limiting hole 22 and embed. The outer wall of the limiting block 74 abuts against the inner wall of the limiting hole 22 and limits the rotation of the fixing ring 51, thereby improving the connection stability between the fixing ring 51 and the water inlet pipe 2. Furthermore, the user can judge the installation status of the water trap based on the flushness of the face of the clamping ring 72 and the end face of the fixing ring 51, or directly judge the tightening status of the fixing ring 51 on the water inlet pipe 2 based on the sound emitted when the limiting block 74 is embedded in the limiting hole 22, further improving the installation efficiency of the water trap.

[0043] The implementation principle of a water trap according to an embodiment of this application is as follows: When the water trap is in use, the fixing ring 51 located in the inlet section 11 is coaxially sleeved on the end of the inlet pipe 2 and screwed tight. The fixing ring 51 located in the outlet section 13 is coaxially sleeved on the end of the outlet pipe 3 and screwed tight. The end of the outlet pipe 3 away from the fixing ring 51 is connected to the end of the sewer. The end of the inlet pipe 2 away from the fixing ring 51 is connected to the end of the drain pipe. The end face of the inlet pipe 2 and the end face of the inlet section 11 are clamped one-to-one with the two sides of the clamping ring 61 in the axial direction to form a seal. The inlet of the filter cylinder 4 is connected to the inlet section 11. The end faces are flush, and the opening of the filter cylinder 4 faces the inner cavity of the inlet pipe 2. Water in the drain pipe enters the inner cavity of the arc-shaped pipe 1 after being filtered by the filter cylinder 4 through the inlet pipe 2. When the inner cavity of the filter cylinder 4 is clogged with impurities, the user only needs to unscrew the fixing ring 51 to separate the arc-shaped pipe 1, the inlet pipe 2 and the outlet pipe 3. Impurities accumulate in the inner cavity of the filter cylinder 4, and the user only needs to clean the inner wall of the filter cylinder 4, which improves the cleaning efficiency of the water trap and eliminates the need for professional plumbers to disassemble the drain pipe for cleaning, thereby reducing the cost of using the water trap.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
