In this embodiment, the fixing member 2 is a cover body coupled to the base 1, and the cover body includes a fixing portion 21 spaced from the base 11, in this embodiment, the fixing member 2 is flat and is used for being coupled to a top edge of the surrounding wall 12 of the base 1, and a hole 22 is provided in a center of the fixing member 2, and the fixing portion 21 may be a surrounding area of the fixing member 2 where the hole 22 is provided in the center, and when the fixing member 2 is coupled to the base 1, the fixing portion 21 is spaced above the base 11 of the base 1.

The operating member 3 is arranged on the base 1 and is operable to be displaced between a rope retrieving position and a rope releasing position. In this embodiment, the operating member 3 includes an operating portion 31 and two arcuate segments 32 connecting the operating portion 31. The two arc segments 32 are connected to each other in a substantially C-shape, and the operating portion 31 is connected between the two arc segments 32 and protrudes outward in a direction away from the C-shaped opening, so that the two arc segments 32 are located on both sides of the operating portion 31. In this embodiment, the top surface of the base 11 of the base 1 is recessed along the inner side of the surrounding wall 12 to form a substantially C-shaped arc groove 13, when the operating member 3 is disposed on the base 1, two connected arc segments 32 are located in the arc groove 13, and the operating portion 31 passes out of the base 1 through the slot 121 of the surrounding wall 12, and the operating portion 31 is laterally displaced along the slot 121 to drive the connected arc segments 32 to slide in the arc groove 13.

The pair of arm portions 4 are provided to the base 1 and are connected to the operating element 3 so as to be interlocked with the operating element 3. In this embodiment, two arm portions 4 are respectively pivoted to two arc-shaped sections 32 and disposed opposite to each other, and the two arm portions 4 are respectively disposed on opposite sides of the base 1, and the two arm portions 4 are staggered in vertical positions, each arm portion 4 has a first end 41 pivoted to the arc-shaped section 32 and a second end 42 far from the first end 41, a chute 43 is disposed between the first end 41 and the second end 42 of each arm portion 4, and a hole 421 is disposed at the second end 42 of each arm portion 4, whose function will be described later. In this embodiment, one arm 4 has a straight rod shape, and the other arm 4 has a substantially L-shape overall and further includes an extension arm 44 extending from the second end 42 thereof and a water stop valve 45 disposed at the end of the extension arm 44. In addition, since the arm 4 is interlocked with the operation member 3, in order to guide the displacement of the arm 4, the base 1 of the present embodiment further includes two protruding shafts 14 disposed on the base 11, when the two arm 4 are disposed on the base 1, the two protruding shafts 14 respectively penetrate the sliding grooves 43 of the two arm 4, and when the arm 4 is interlocked with the operation member 3 and displaced relative to the base 1, the protruding shafts 14 slide in the sliding grooves 43.

Referring to fig. 3, 4A and 5A, when the brewing assembly 5 is placed in the cup 101 for brewing, the string 52 is located by passing upward through the hole 111 of the base 11 of the base 1, the holes 421 of the second ends 42 of the two arms 4 and the holes 22 of the fixing portion 21 of the fixing member 2, in this embodiment, the brewing assembly 5 further has a rod 53 connected to the end of the string 52, and is blocked on the fixing member 2 by the rod 53, so that the brewing assembly 5 is in a suspended state, and the free end of the string 52 is located on the fixing member 2. The fixing member 2 may be configured in other manners to provide the free end positioning of the rope 52 according to the usage environment of the entire brewing assembly retraction mechanism 100.

When the operating member 3 is in the rope releasing position, the second ends 42 of the two arm portions 4 overlap in opposite directions, at this time, the holes 421 of the two arm portions 4 at the second ends 42 are aligned with the holes 111 of the base portion 11 of the base 1 and the holes 22 of the fixing portion 21 of the fixing member 2, and the rope 52 of the brewing assembly 5 is in a straight line vertical state, so that the brewing material 51 is located at a lower position in the cup 101, that is, the brewing material 51 is immersed in water contained in the cup 101, and here, because the positions of the two arm portions 4 at the second ends 42 are staggered up and down, the arm portions 4 can be prevented from interfering with each other in the displacement process, and a longer displacement distance is provided. When the user does not want to continue to soak the brewing material 51, the operation portion 31 of the operation member 3 is moved along the slot 121 (as shown by the arrow direction in fig. 4A) to switch to the rope-collecting position, and as shown in fig. 4B and 5B, the two arm portions 4 are driven by the two arc portions 32 to pivot and swing in the direction away from each other, so that the second end portions 42 of the two arm portions 4 are respectively moved laterally in the direction away from each other, and the rope 52 is pulled, thereby driving the brewing material 51 in the cup 101 to rise and be separated from the state of being soaked in water until the holes 421 of the second end portions 42 of the two arm portions 4 are respectively close to the arc portions 32 pivoted by the holes, as shown in fig. 5B, and at this time, the operation member 3 is at the rope-collecting position. It should be noted that, since the two arm portions 4 respectively pull the rope 52 to move away from each other, when the operating member 3 moves to the rope-collecting position, it is achieved that the rope 52 is pulled and collected in the base 1 close to the length of twice the diameter of the base 11 of the base 1.

When the user needs to soak the brewing material 51 in the water, the operating part 31 is pulled again to reversely displace, so that the operating part 3 returns to the rope releasing position, and the arm 4 can be driven to return to the hole 421 to align with the hole 111 of the base 11 of the base 1 and the hole 22 of the fixing part 21 of the fixing part 2, so that the rope 52 of the brewing assembly 5 is in a straight line vertical state.

Therefore, by arranging the plurality of arms 4 and arranging the arms 4 to be located at opposite sides of the base 1 and capable of moving away from each other, the plurality of arms 4 can be simultaneously actuated by the operation of the single operation member 3 to pull the rope 52 in different directions, thereby enabling the rope 52 to be pulled in a maximum amount, increasing the lifting height of the brewing material 51, and having a larger lifting amount under the limited space of the base 1. The larger pulling and lifting amount is helpful to ensure that the brewing object 51 can be completely pulled out of the water surface, and by matching with the structure of the brewing assembly 5 in the scheme, the brewing object 51 can be continuously pulled up to touch the bottom of the base 1 after being pulled out of the water surface, and is continuously pulled up for a certain distance so as to compress the brewing object 51, thereby extruding water and air in the brewing object 51, reducing the weight of the brewing object 51 and further reducing the gravity load of the arm parts 4 when the operating member 5 is in the rope collecting position, and being convenient for the brewing object 51 with the fully extruded air to be submerged in water again more smoothly when the brewing object 51 needs secondary back flushing.

In addition, since the weight of the brewing assembly 5 is generally increased after the brewing assembly is immersed in water, in the process of moving the operating member 3 to the rope collecting position, in order to make the linkage mechanism of the operating member 3 and the arm portion 4 more labor-saving in operation and more stable in structure, the arm portion 4 is pivoted to the arc-shaped section 32, and the protruding shaft 14 penetrates through the sliding groove 43 of the arm portion 4 to serve as a fulcrum for the movement of the arm portion 4, so that the problem that the rope collecting operation is more labor-saving due to the overlong force arm of the force arm 4 and the excessive weight of the brewing assembly can be solved.

Furthermore, since the water stop valve 45 is disposed at the end of the extension arm 44 of one arm 4, when the operating member 3 is operated to the rope-collecting position, the water stop valve 45 can be just moved to the hole 111 of the base 11 to block the hole 111 of the base 11, thereby preventing water in the cup 101 from leaking into the base 1 after the brewing process is completed.

In addition to the above structure, since the operating member 3 is capable of being operated at the rope winding position and the rope unwinding position, in order to ensure the positioning of the operating member 3 at the two positions and to improve the operation feeling of the user, referring to fig. 6, another variation of the operating member 3 'of the present embodiment is shown in fig. 6, in this way, two ends of the arc segments 32' are each formed with a first engaging portion 34, the first engaging portion 34 of the present embodiment is a slot formed at the end of the arc segment 32, and two second engaging portions 15 are also formed on the displacement path of the arc segments 32 of the base 1, and in this embodiment, the second engaging portions 15 are the clamping blocks 15 formed at the positions of the arc grooves 13 near the two ends, so that the two second engaging portions 15 are respectively near the first engaging portions 34 corresponding to the ends of the two arc segments 32. When the operating element' is displaced to the rope collecting position or the rope releasing position, one of the first engaging portions 34 is engaged with the corresponding second engaging portion 15, so that the operating element 3 can be temporarily positioned at the rope collecting position or the rope releasing position.

Referring to fig. 7 to 9, in a second embodiment of the retraction mechanism of the brewing assembly according to the present invention, the difference between the second embodiment and the first embodiment is that the operating portion 31' of the operating member 3″ includes a connecting section 33 and a fixing member 2 protruding from the two arc sections 32 in an upward direction, the connecting section 33 is connected to the fixing member 2, and the fixing member 2 is rotatably disposed on the base 1, such that the operating member 3″ can be displaced to the rope retraction position and the rope retraction position by rotating the fixing member 2 through the connecting section 33, and the arm 4 is further driven to displace. In other words, in the second embodiment, the fixing member 2 can also be regarded as a part of the operation member 3 ".

Referring to fig. 3, 10-11, a third embodiment of the retracting mechanism of the brewing assembly according to the present invention is shown. In comparison with the first embodiment, the base 1 'of the third embodiment omits the surrounding wall, and the base 11 of the base 1' is also flat and formed with the arc-shaped groove 13. The operating member 3 '"further comprises a surrounding wall 34, and the arc-shaped section 32 of the operating member 3'" is connected to the inner wall surface of the surrounding wall 34, and the operating portion 31 protrudes from the outer wall surface of the surrounding wall 34 for being pulled. In other words, the third embodiment can also be regarded as the first embodiment in which the surrounding wall 12 is formed in the operation piece 3 instead of the base 1.

By the structural design of the operating member 3 '"of the third embodiment, the user can move the entire operating member 3'" between the rope winding position and the rope unwinding position by pulling the operating portion 31.

In summary, the above-mentioned structure of the brewing assembly retracting mechanism 100 of the present invention can greatly increase the height of the brewing assembly 5 that is pulled up by the arrangement of the multiple arms 4, compared with the prior art, and by increasing the height of the pulling up, in addition to ensuring that the brewing assembly 51 can be pulled out of the water surface completely, by matching the structure of the brewing assembly 5 of the present invention, the brewing assembly 51 can be pulled up continuously to compress the brewing assembly 51, thereby squeezing out the water and air in the brewing assembly 51, reducing the weight of the brewing assembly 51 and further reducing the weight load of the arms 4 when the operating member 5 is in the rope retracting position, and secondly, by the arrangement of the multiple arms 4 and the assistance of the protruding shaft 14 as the supporting point, the user can also save more effort in operation, and by the structural design of the operating member 3 and the way of the opposite arrangement of the arms 4, the effect of increasing the height of the brewing assembly 5 can be achieved without increasing the volume and the inner space of the base 1.

However, the foregoing is only illustrative of the present invention and is not to be construed as limiting the scope of the invention, which is defined by the appended claims and their equivalents.
