Description

Technical Field

[0001] This utility model relates to the field of teaware technology, specifically a filter structure and a teacup. Background Technology

[0002] In the field of teaware technology, the filter structure of a teacup is a key component for separating tea leaves from tea soup and enhancing the tea-drinking experience. Its core function is to intercept tea leaves during the brewing process and prevent them from being consumed along with the tea soup.

[0003] Current teacup filters are mostly simple tea strainer designs, commonly including a ring-shaped filter fixed to the rim of the cup. This type of traditional filter has the following drawbacks: When tea leaves are steeped directly in the cup, the remaining tea leaves easily adhere to the cup walls and the gaps in the filter components when the tea leaves are changed. This is difficult to clean quickly and usually requires multiple rinses, making the process cumbersome. Utility Model Content

[0004] The purpose of this invention is to provide a filter structure and a teacup to solve the problems mentioned in the background art.

[0005] The objective of this utility model can be achieved through the following technical solutions: On the one hand, a filtering structure is provided, including: The mounting ring has an annular groove in the middle of its inner wall. The top surface of the mounting ring has multiple circumferentially arranged sliding grooves near the inner wall, and the sliding grooves are connected to the annular groove. The outer periphery of the mounting ring has multiple circumferentially arranged cylindrical mounting grooves, and each cylindrical mounting groove is provided with an elastic snap-fit ​​component, which includes a sphere. The filter disc is installed in the mounting ring via the annular groove and the sliding groove; A filter cartridge is fixedly installed at the bottom of the mounting ring, and a limiting ring one and a limiting ring two are fixedly installed on the inner wall of the filter cartridge at the top and bottom positions respectively; A bottom filter assembly is slidably installed in the filter cartridge, and the bottom filter assembly is rotatably connected to the bottom surface of the filter disc.

[0006] Furthermore, a plurality of locking blocks are fixedly installed on the periphery of the filter disc, which cooperate with the sliding groove and the annular locking groove. The number of the locking blocks is equal to the number of the sliding grooves, and the locking blocks are arranged in a circumferential array about the axis of the filter disc. When the filter disc and the mounting ring are in the installation state, the periphery of the filter disc slides in contact with the inner wall of the mounting ring, the bottom surface of the filter disc contacts the top surface of the limiting ring, and the end of the locking block away from the filter disc is slidably locked in the annular locking groove. A lifting handle is fixedly installed at the center of the top surface of the filter disc.

[0007] Furthermore, the bottom filter assembly includes a slip ring slidably installed in the filter cylinder, and a bottom filter is fixedly installed at the bottom end of the slip ring. The bottom filter is an inverted hollow cone structure, and a connecting rod coaxial with the filter cylinder is fixedly connected to the center of the inner wall of the bottom filter. The top end of the connecting rod is rotatably connected to the bottom surface of the filter disc.

[0008] Furthermore, the elastic snap-fit ​​assembly includes a column that is slidably installed in the cylindrical mounting groove, a spring that is fixedly connected between the column and the inner end face of the cylindrical mounting groove, and the sphere that is embedded at the other end of the column.

[0009] On the other hand, a teacup is also provided, including a cup body and the above-mentioned filter structure. The top of the cup body is provided with a suitable cup lid, and a retaining ring is fixedly installed on the inner wall of the cup body near the top. The inner wall of the retaining ring has an annular groove that cooperates with the elastic snap-fit ​​assembly.

Detailed Implementation

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Example 1: Please see Figures 3 to 10 In this embodiment of the present invention, a filter structure includes: Mounting ring 2, an annular groove 14 is provided in the middle of the inner wall of mounting ring 2, and multiple circumferentially arranged sliding grooves 5 are provided on the top surface of mounting ring 2 near the inner wall, and the sliding grooves 5 are connected to the annular groove 14. Multiple circumferentially arranged cylindrical mounting grooves 8 are provided on the outer periphery of mounting ring 2, and elastic snap-fit ​​components are provided in the cylindrical mounting grooves 8, including spheres 4. The filter disc 6 is installed in the mounting ring 2 via the annular groove 14 and the sliding groove 5; The filter cartridge 1 is fixedly installed at the bottom of the mounting ring 2. Limiting ring 15 and limiting ring 26 are fixedly installed on the inner wall of the filter cartridge 1 at the top and bottom positions respectively. The bottom filter assembly is slidably installed in the filter cartridge 1, and the bottom filter assembly is rotatably connected to the bottom surface of the filter disc 6.

[0015] The filter disc 6 is installed into the mounting ring 2 via the annular groove 14 and the sliding groove 5, forming a stable assembly between the filter disc 6 and the mounting ring 2. The filter cylinder 1 is fixed to the bottom end of the mounting ring 2, and the bottom filter assembly is slidably installed in the filter cylinder 1 and rotatably connected to the bottom surface of the filter disc 6. At the same time, the elastic snap-fit ​​assembly is assembled in the cylindrical mounting groove 8 of the mounting ring 2. This assembly method achieves precise positioning and stable connection of each component of the filter structure, avoiding the problem of tea leakage caused by displacement of the filter components.

[0016] Example 2: Please see Figure 4 and Figures 6-9 Based on embodiment 1, multiple locking blocks 13 are fixedly installed on the periphery of the filter disc 6 to cooperate with the sliding groove 5 and the annular locking groove 14. The number of multiple locking blocks 13 is equal to the number of multiple sliding grooves 5, and the multiple locking blocks 13 are arranged in a circumferential array about the axis of the filter disc 6. When the filter disc 6 and the mounting ring 2 are in the installation state, the periphery of the filter disc 6 slides in contact with the inner wall of the mounting ring 2, the bottom surface of the filter disc 6 contacts the top surface of the limiting ring 15, and the end of the locking block 13 away from the filter disc 6 is slidably locked in the annular locking groove 14. A lifting handle 7 is fixedly installed at the center of the top surface of the filter disc 6.

[0017] When installing the filter disc 6, align the locking block 13 on the periphery of the filter disc 6 with the sliding groove 5 of the mounting ring 2, slide it down the sliding groove 5 to the position of the annular locking groove 14, rotate the filter disc 6 so that the locking block 13 is engaged in the annular locking groove 14, at which point the bottom surface of the filter disc 6 contacts the top surface of the limiting ring 15, thus fixing the filter disc 6; when disassembling, hold the lifting handle 7 and rotate the filter disc 6 so that the locking block 13 is aligned with the sliding groove 5, and lift it up to separate the filter disc 6 from the mounting ring 2.

[0018] The lifting handle 7 makes it easier to disassemble and assemble the filter disc 6 without the need for additional tools; the design of the locking block 13, the annular locking groove 14, and the sliding groove 5 ensures the stability of the filter disc 6 after installation, effectively preventing the filter disc 6 from loosening and shifting when brewing tea. At the same time, the detachable structure makes it easy to clean the filter disc 6 separately and avoids tea residue residue.

[0019] Example 3: Please see Figure 3 , Figure 6 , Figure 9 and Figure 10 Based on embodiment 2, the bottom filter assembly includes a slip ring 12 slidably installed in the filter cylinder 1, and a bottom filter 3 is fixedly installed at the bottom end of the slip ring 12. The bottom filter 3 is an inverted hollow cone structure. A connecting rod 11 coaxial with the filter cylinder 1 is fixedly connected to the center of the inner wall of the bottom filter 3. The top end of the connecting rod 11 is rotatably connected to the bottom surface of the filter disc 6.

[0020] The bottom filter assembly is slidably engaged with the filter cylinder 1 via a slip ring 12. The bottom filter 3 is an inverted hollow cone structure, which is rotatably connected to the bottom surface of the filter disc 6 via a connecting rod 11. When brewing tea, the tea soup is filtered twice through the filter cylinder 1 and the filter disc 6, achieving efficient separation of tea leaves and tea soup. When changing tea leaves, after separating the filter disc 6, the connecting rod 11 pulls the slip ring 12, causing the bottom filter 3 to slide along the inner wall of the filter cylinder 1. The cone structure of the bottom filter 3 can concentrate and push the tea residue in the filter cylinder 1 to the opening of the filter cylinder 1.

[0021] The cone structure of the bottom filter 3 increases the filtration contact area and improves filtration efficiency. The dual filtration design further ensures the purity of the tea soup. The sliding linkage design of the bottom filter component solves the problem of tea residue being difficult to clean in traditional filtration structures. Tea residue can be quickly and thoroughly removed without multiple rinsings, while also avoiding the problem of tea residue adhering to the cup wall.

[0022] Example 4: Please see Figures 3-5 Based on embodiment 1, the elastic snap-fit ​​assembly includes a column 10 that is slidably installed in a cylindrical mounting groove 8, a spring 9 that is fixedly connected between the column 10 and the inner end face of the cylindrical mounting groove 8, and a ball 4 that is embedded at the other end of the column 10.

[0023] When the filter structure is assembled with external components, the ball 4 is compressed, pushing the column 10 to compress the spring 9. Once the ball 4 is aligned with the matching slot, the spring 9 returns to its original position, pushing the column 10 to lock the ball 4 into the slot, achieving a secure connection. For disassembly, applying a pulling force causes the ball 4 to retract, releasing the connection restriction. This elastic snap-fit ​​structure enables quick assembly and disassembly of the filter structure, making operation more convenient.

[0024] Example 5: Please see Figure 1 and Figure 2 This embodiment provides a teacup, including a cup body 17 and the above-mentioned filter structure. The top of the cup body 17 is provided with a suitable cup lid 18. A retaining ring 19 is fixedly installed on the inner wall of the cup body 17 near the top. The inner wall of the retaining ring 19 has an annular groove 20 for use with the elastic snap-fit ​​assembly. When the filter structure and the cup body 17 are in the installed state, the outer periphery of the mounting ring 2 slides in contact with the inner wall of the retaining ring 19, and the balls 4 in the multiple sets of elastic snap-fit ​​assemblies are all slidably snapped in the annular groove 20.

[0025] The assembled filter structure is inserted into the cup body 17 via the lifting handle 7. The outer periphery of the mounting ring 2 slides into contact with the inner wall of the retaining ring 19 of the cup body 17. When the ball 4 of the elastic retaining component aligns with the annular groove 20 of the retaining ring 19, the spring 9 resets, causing the ball 4 to engage with the annular groove 20, thus achieving a stable assembly between the filter structure and the cup body 17. When brewing tea, the tea leaves are placed in the filter cylinder 1, and the tea soup flows into the cup body 17 after being filtered through the filter cylinder 1, the bottom filter component, and the filter plate 6. When changing the tea leaves, the lifting handle 7 is pulled up to retract the ball 4, separating the filter structure from the cup body 17. Then, the filter plate 6 is disassembled, the tea leaves are cleaned, and the filter is reassembled following the steps described above.
