Description
Technical Field
[0001] This utility model relates to the technical field of tea tray accessories, and in particular to a detachable tea dregs filter tube. Background Technology
[0002] A tea tray, also known as a tea table, tea tray, or tea sea, is a vessel used to hold tea utensils such as teapots and teacups during tea brewing and to drain wastewater.
[0003] Currently, in the use of tea trays, tea water and tea leaves are usually discharged directly into the drain pipe through the tray's connecting pipe. Due to the lack of an effective filtration structure, tea leaves easily enter the drain pipe with the waste tea and gradually accumulate, causing blockage and affecting normal drainage. Cleaning and maintenance are also very inconvenient. Although some filtration devices exist in existing technologies, most adopt a fixed structure design. When too much tea leaves accumulate, it not only significantly reduces the drainage speed but also makes it difficult to disassemble and clean quickly. After long-term use, tea stains can easily affect the filtration effect and may even breed bacteria. In addition, the connection between traditional filtration devices and drain pipes is often quite complex, requiring tools or cumbersome operations for disassembly, which cannot meet the user's actual needs for convenient cleaning and regular maintenance. Therefore, this paper proposes a detachable tea leaf filter fitting to overcome the above-mentioned defects. Utility Model Content
[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a detachable tea dregs filter pipe.
[0005] To achieve the above objectives, this utility model adopts the following technical solution: a detachable tea dregs filter pipe, comprising a fixed pipe, a 6 / 8" pipe fixedly connected to the top of the fixed pipe, a tea tray connecting pipe fixedly connected to the outer side of the top of the 6 / 8" pipe, an internal thread structure at the bottom of the inner wall of the fixed pipe, an external thread structure threaded to the inner side of the internal thread structure, a filter pipe body fixedly connected to the bottom end of the external thread structure, a metal filter screen fixedly connected to the lower inner side of the filter pipe body, a 4 / 8" pipe fixedly connected to the bottom of the filter pipe body, a drain pipe slidably connected to the outer side of the lower part of the 4 / 8" pipe, an installation ring fixedly connected to the outer side of the middle of the fixed pipe, a first rubber ring fixedly connected to the inner side of the installation ring, a connecting rod fixedly connected to the middle of the rear end face of the installation ring, a fixed ring fixedly connected to the end of the connecting rod away from the installation ring, and a second rubber ring fixedly connected to the inner side of the fixed ring.
[0006] As a further description of the above technical solution: the inner side of the first rubber ring contacts the surface of the fixed pipe, the inner side of the fixed ring is fixedly connected to the outer side of the second rubber ring, the inner side of the second rubber ring contacts the surface of the drain pipe, and the top of the filter pipe body contacts the bottom of the fixed pipe. This allows for the filtration of waste tea entering the fixed pipe from the tea tray connecting pipe and the tea residue in the waste tea. At the same time, after the tea residue is blocked by the metal filter screen for a long time, reducing the flow rate of waste tea to the drain pipe, the fixed pipe and the filter pipe body can be directly separated by rotating the filter pipe body, making it convenient for the user to clean the filter pipe body.
[0007] As a further description of the above technical solution: an annular groove is provided at the bottom of the inner wall of the fixed tube, and the internal thread structure is set in the annular groove. The number of thread turns of the internal thread structure and the external thread structure is less than 3, so as to realize the purpose of disassembling the fixed tube from the filter tube body and facilitate the subsequent cleaning of the tea residue filtered on the metal filter screen.
[0008] As a further description of the above technical solution: the inner diameter of the drain pipe matches the outer diameter of the 1 / 4-point pipe, the longitudinal cross-section of the drain pipe is L-shaped, and the longitudinal length of the drain pipe is twice the length of the 1 / 4-point pipe. When the filter pipe body is separated from the fixed pipe, the 1 / 4-point pipe at the bottom of the filter pipe body can be inserted into the drain pipe, thus preventing the filter pipe body from shifting downwards during disassembly and getting stuck and unable to be removed.
[0009] As a further description of the above technical solution: the mounting ring is formed by two semi-circular retaining rings fixed by bolts, and the top of the connecting rod is fixed in the middle of the rear end face of the retaining ring behind the fixed pipe. The design of the mounting ring, connecting rod and fixed ring can make the fixed pipe and the drain pipe fixedly connected, so as to avoid the drain pipe from detaching along with the filter pipe body when the filter pipe body is disconnected from the fixed pipe connection.
[0010] As a further description of the above technical solution: the first rubber ring inside the mounting ring is semi-circular in shape, and the second rubber ring inside the fixing ring is circular in shape. The first rubber ring and the second rubber ring are made of the same material. The setting of the first rubber ring and the second rubber ring can increase the friction between the surface of the fixing pipe and the surface of the drain pipe, and avoid the vibration generated when the waste tea flows from the fixing pipe and the drain pipe, which would cause the fixing pipe and the drain pipe to detach from the fixing of the mounting ring and the fixing ring.
[0011] As a further description of the above technical solution: the metal filter screen is circular and fixed inside the filter tube body at the lower position. The metal filter screen has a mesh size of 40 mesh, which can filter the waste tea entering the fixed tube from the tea tray connecting pipe and the tea residue in the waste tea, allowing only the waste tea to be discharged from the drain pipe, thus avoiding the situation where the tea residue clogs the drain pipe.
[0012] This utility model has the following beneficial effects:
[0013] This utility model designs a detachable tea dregs filter tube, which, through the design and cooperation of the filter tube body and the metal filter screen, allows the device to filter waste tea and tea dregs entering the fixed tube from the tea tray connection tube, allowing only waste tea to be discharged through the drain pipe, thus avoiding tea dregs clogging the drain pipe. At the same time, an installation ring is set on the outside of the fixed tube, and a connecting rod connecting to the fixed ring on the outside of the drain pipe is set behind the installation ring. The fixed tube and the filter tube body are connected by internal and external threaded structures. After the tea dregs are blocked by the metal filter screen for a long time, reducing the flow rate of waste tea to the drain pipe, the fixed tube and the filter tube body can be directly separated by rotating the filter tube body, making it convenient for users to clean the filter tube body.

[0020] Reference Figures 1 to 4This utility model provides a detachable tea dregs filter pipe, including a fixed pipe 1, a six-point pipe 2 at the top of the fixed pipe 1, the outer side of the top of the six-point pipe 2 is inserted into the lower part of the tea tray connecting pipe 3 and fixed, an internal thread structure 12 is opened at the bottom of the inner wall of the fixed pipe 1, the inner side of the internal thread structure 12 and the external thread structure 13 are spirally interlocked, a filter pipe body 4 is set at the bottom of the external thread structure 13, a metal filter screen 14 is inserted into the lower part of the inner side of the filter pipe body 4 and fixed, a four-point pipe 5 is set at the bottom of the filter pipe body 4, the lower outer side of the four-point pipe 5 is inserted into the upper part of the drain pipe 6 and slides, a mounting ring 7 is fixed to the middle outer side of the fixed pipe 1 by bolts, a first rubber ring 10 is glued to the inner side of the mounting ring 7 by adhesive, a connecting rod 8 is welded to the middle of the rear end face of the mounting ring 7, a fixed ring 9 is welded to the end of the connecting rod 8 away from the mounting ring 7, and a second rubber ring 11 is glued to the inner side of the fixed ring 9 by adhesive.
[0021] The inner side of the first rubber ring 10 contacts the surface of the fixed pipe 1, the inner side of the fixed ring 9 is fixedly connected to the outer side of the second rubber ring 11, the inner side of the second rubber ring 11 contacts the surface of the drain pipe 6, and the top of the filter tube body 4 contacts the bottom of the fixed pipe 1. This allows for the filtration of waste tea entering the fixed pipe 1 from the tea tray connecting pipe 3 and the tea residue in the waste tea. At the same time, after the tea residue is blocked by the metal filter screen 14 for a long time, reducing the flow rate of waste tea to the drain pipe 6, the fixed pipe 1 and the filter tube body 4 can be separated directly by rotating the filter tube body 4, making it convenient for the user to clean the filter tube body 4.
[0022] As a further implementation of the above technical solution: an annular groove is provided at the bottom of the inner wall of the fixed tube 1, and the internal thread structure 12 is set in the annular groove. The number of thread turns of the internal thread structure 12 and the external thread structure 13 is less than 3, so as to realize the purpose of disassembling the fixed tube 1 from the filter tube body 4, which facilitates the subsequent cleaning of the filtered tea residue on the metal filter screen 14.
[0023] As a further implementation of the above technical solution: the inner diameter of the drain pipe 6 matches the outer diameter of the 1 / 4-inch pipe 5, the longitudinal cross-section of the drain pipe 6 is L-shaped, and the longitudinal length of the drain pipe 6 is twice the length of the 1 / 4-inch pipe 5. When the filter pipe body 4 is separated from the fixing pipe 1, the 1 / 4-inch pipe 5 at the bottom of the filter pipe body 4 can be inserted into the drain pipe 6, so as to prevent the filter pipe body 4 from moving down as a whole during disassembly and getting stuck and unable to be removed.
[0024] As a further implementation of the above technical solution: the mounting ring 7 is formed by two semi-circular retaining rings fixed by bolts, and the top of the connecting rod 8 is fixed in the middle of the rear end face of the retaining ring behind the fixed pipe 1. The design of the mounting ring 7, the connecting rod 8 and the fixing ring 9 can make the fixed pipe 1 and the drain pipe 6 fixedly connected, so as to avoid the drain pipe 6 from detaching along with the filter pipe body 4 when the filter pipe body 4 is disconnected from the connection of the fixed pipe 1.
[0025] As a further implementation of the above technical solution: the first rubber ring 10 inside the mounting ring 7 is semi-circular in shape, and the second rubber ring 11 inside the fixing ring 9 is circular in shape. The first rubber ring 10 and the second rubber ring 11 are made of the same material. The setting of the first rubber ring 10 and the second rubber ring 11 can increase the friction between the surface of the fixing pipe 1 and the surface of the drain pipe 6, and prevent the vibration generated when the waste tea flows from the fixing pipe 1 and the drain pipe 6 from detaching from the fixing ring 7 and the fixing ring 9.
[0026] As a further implementation of the above technical solution: the metal filter 14 is circular and fixed inside the filter tube body 4 at the lower position. The metal filter 14 has a mesh size of 40 mesh, which can filter the waste tea entering the fixed tube 1 from the tea tray connecting pipe 3 and the tea residue in the waste tea, allowing only the waste tea to be discharged from the drain pipe 6, thus avoiding the situation where the tea residue blocks the drain pipe 6.
[0027] Working principle:
[0028] When using this utility model, the six-point pipe 2 at the top of the fixed pipe 1 is inserted into the bottom of the tea tray connecting pipe 3. Then, the mounting ring 7 is fixed to the outside of the fixed pipe 1. The first rubber ring 10 on the inside of the mounting ring 7 is tightly attached to the surface of the fixed pipe 1. After the mounting ring 7 is connected and fixed to the fixed pipe 1 with bolts, the drainage pipe 6 pre-buried under the tea table is inserted from bottom to top into the fixing ring 9 below the fixed pipe 1. The second rubber ring 11 on the inside of the fixing ring 9 can increase the friction between the fixing ring 9 and the surface of the drainage pipe 6. At this time, the inside of the drainage pipe 6 also wraps around the outside of the four-point pipe 5 at the bottom of the filter pipe body 4. The connecting rod 8 between the mounting ring 7 and the fixing ring 9 can ensure the fixation between the mounting ring 7 and the fixing ring 9. After installation, it can be used. Waste tea and tea dregs enter the fixed pipe 1 and the filter pipe body 4 from the tea tray connecting pipe 3. The tea dregs are filtered by the filter pipe body. The metal filter 14 at the bottom of the filter tube 4 blocks the waste tea, which passes through the metal filter 14 to reach the drain pipe 6. When it is necessary to clean the tea residue blocked by the metal filter 14 regularly, the user can pinch the filter tube body 4 and rotate it counterclockwise. The filter tube body 4 drives the external thread structure 13 at the top to rotate and disengage from the internal thread structure 12 at the bottom inside the fixed tube 1. At this time, the filter tube body 4 drives the quarter-point tube 5 to move into the lower part of the drain pipe 6 until the fixed tube 1 and the filter tube body 4 are completely disengaged. Then, the filter tube body 4 can be pulled out from the drain pipe 6 and cleaned. After cleaning, insert the quarter-point tube 5 at the bottom of the filter tube body 4 into the drain pipe 6 first, so that the filter tube body 4 is perpendicular to the fixed tube 1. Then, move the filter tube body 4 upward until the external thread structure 13 contacts and rotates with the internal thread structure 12. The fixed tube 1 and the filter tube body 4 can then be reconnected.
