Description

Technical Field

[0001] The present application relates to the technical field of water cups, and in particular to a connecting rod type stroke amplification mechanism for a cup cover, a cup cover and a tea brewing cup. Background Art

[0002] A tea brewing cup is a cup used for brewing tea in daily life. In order to improve the convenience of brewing tea, a tea compartment is usually placed in the cup or a disposable tea bag with a traction belt is used. The user places tea leaves in the tea compartment or the tea bag in the cup and then fills it with boiling water to achieve a quick tea brewing operation.

[0003] However, in the process of brewing tea, since the tea leaves are placed in the tea compartment or the tea bag is placed in the water cup, the tea leaves in the tea compartment or the tea bag are soaked in water for a long time, and the concentration of the tea cannot be well controlled, thereby affecting the taste of the tea.

[0004] In order to improve the problem of poor control of tea concentration, a tea-brewing cup with tea-water separation function has appeared on the market. Specifically, the cover of the tea-brewing cup is provided with a magnetic structure and a switch, and a tea compartment that can be magnetically matched with the magnetic structure is placed in the cup body of the tea-brewing cup. When in use, the user turns the cup over to make the tea compartment magnetically connected to the cover, thereby separating the tea compartment from the tea. When it is time to brew tea, the user uses the switch to release the magnetic connection between the magnetic structure and the tea compartment, so that the tea compartment falls into the water and the tea brewing operation is performed again, thereby achieving better control of the tea concentration.

[0005] However, for some larger tea cups, a tea cup filled with water has a certain weight, and it is not easy to flip the tea cup, which makes the tea cup with a magnetic suction structure less convenient to use, and therefore further improvement is needed. Utility Model Content

The two groups of connecting rod structures are respectively located on both sides of the traction belt to facilitate the spatial arrangement of the two groups of connecting rod structures on the cup cover base, thereby helping to avoid the two groups of connecting rod structures from interfering with each other during the winding or unwinding process.

[0034] Preferably, the parts where the two groups of connecting rods are rotatably connected to the driving assembly are stacked up and down.

The upper end of the traction belt 4 passes through the cup cover base 1 upward and is fixedly connected to the upper surface of the cup cover base 1, so that the traction belt 4 passes through the upper end part of the cup cover base 1 and is close to the upper surface of the cup cover base 1. At the same time, the traction belt 4 is passed through the connecting rod structure 2. The connecting rod structure 2 is arranged on the upper surface of the cup lid base 1 to amplify the stroke of the traction belt 4. The traction belt 4 is connected to the connecting rod structure 2. The driving component 3 drives the connecting rod structure 2 to make the traction belt 4 perform a stroke amplification movement. The driving component 3 is movably connected to the cup lid base 1 to drive the connecting rod structure 2 to move so as to reel in or unreel the traction belt 4, and the stroke amplification is achieved during the reeling or unreeling process. It should be noted that the input stroke of the driving component 3 to the connecting rod structure 2 is smaller than the output stroke of the traction belt 4.

[0106] Reference Figure 1 and Figure 2The connecting rod structure 2 includes a pull block 21, a connecting rod 22 and a guide member 23. The pull block 21 is arranged in a vertical block shape. The pull block 21 is horizontally slidably connected to the upper surface of the cup cover base 1. One end of the pull block 21 is movably sleeved on the traction belt 4, one end of the connecting rod 22 is rotatably connected to the driving component 3, and the other end of the connecting rod 22 is rotatably connected to the end of the pull block 21 away from the traction belt 4. The guide member 23 is fixedly arranged on the cup cover base 1 and is located on the side of the traction belt 4 for guiding the movement of the pull block 21, and the guiding direction of the guide member 23 to the pull block 21 intersects with the moving direction of the driving component 3, and the connecting rod 22 intersects with the straight line where the moving direction of the driving component 3 is located.

[0107] When the driving component 3 moves toward the direction approaching the pulling block 21, the driving component 3 drives the pulling block 21 to move toward the side in the length direction of the traction belt 4 through the connecting rod 22, and the guide member 23 guides the movement of the pulling block 21. The movement of the pulling block 21 drives the traction belt 4 to reel in. At this time, the reeling length of the traction belt 4 is greater than the moving distance of the driving component 3, thereby realizing the stroke amplification function of the traction belt 4 during the reeling process; when the driving component 3 moves in the direction away from the pulling block 21, the driving component 3 drives the pulling block 21 to move and reset through the connecting rod 22, and the guide member 23 guides the movement and reset of the pulling block 21. The reset movement of the pulling block 21 drives the traction belt 4 to unwind. At this time, the unwinding length of the traction belt 4 is also greater than the moving distance of the driving component 3, thereby realizing the stroke amplification function of the traction belt 4 during the unwinding process.

[0108] Reference Figure 1 and Figure 2 , one end of the connecting rod 22 is sleeve-connected with the driving assembly 3, and the other end of the connecting rod 22 is sleeve-connected with the pulling block 21. In this embodiment, a first sleeve 5 is vertically fixedly provided at one end of the connecting rod 22, and at the same time, the driving assembly 3 includes a vertically provided first sleeve column 31, and the first sleeve 5 is rotatably sleeved on the first sleeve column 31 to realize the rotational connection between the connecting rod 22 and the driving assembly 3; a second sleeve 6 symmetrical to the first sleeve 5 is vertically fixedly provided at the other end of the connecting rod 22, and a second sleeve column 7 is vertically fixedly provided at one end of the pulling block 21 away from the traction belt 4, and the second sleeve 6 is rotatably sleeved on the second sleeve column 7 to realize the rotational connection between the connecting rod 22 and the pulling block 21. In other embodiments, a third sleeve column may be provided at one end of the connecting rod 22, the driving assembly 3 includes a third sleeve, and the third sleeve is rotatably sleeved on the third sleeve column to realize the rotational connection between the connecting rod 22 and the driving assembly 3; a fourth sleeve column may be provided at the other end of the connecting rod 22, the pull block 21 is provided with a fourth sleeve, and the fourth sleeve is rotatably sleeved on the fourth sleeve column to realize the rotational connection between the connecting rod 22 and the pull block 21. In addition, the rotational connection can also be realized by hingedly connecting the two ends of the connecting rod 22 to the driving assembly 3 and the pull block 21, as long as the rotation function is realized, which will not be described in detail here.

[0109] Reference Figure 1 and Figure 2 , the guide member 23 is set as a guide rail structure, the length direction of the guide rail structure intersects with the moving direction of the driving assembly 3. In this embodiment, the length direction of the guide rail structure is perpendicular to the moving direction of the driving assembly 3. Specifically, the guide member 23 includes two guide plates 231 arranged in parallel and spaced apart. The two guide plates 231 are fixedly arranged on the upper surface of the cup cover base 1 and are located on the same side of the traction belt 4. There is a gap between the two guide plates 231 for the pull block 21 to move. The end of the pull block 21 away from the traction belt 4 faces the two guide plates 231 and penetrates into the gap between the two guide plates 231. The length direction of the guide plate 231 intersects with the moving direction of the driving assembly 3, so that the movement of the pull block 21 can pull the traction belt 4 to be wound or unwound. In other embodiments, the guide member 23 can also be set as a sliding seat, the length direction of the sliding seat intersects with the moving direction of the driving assembly 3, and the pull block 21 is sleeved and slid on the sliding seat along the length direction of the sliding seat to guide the movement of the pull block 21. No further details are given here.

[0110] The implementation principle of a connecting rod stroke amplification mechanism for a cup cover in Example 1 of the present application is as follows: the driving component 3 moves toward the direction approaching the pull block 21, and the driving component 3 drives the pull block 21 to move along the length direction of the guide plate 231 through the connecting rod 22, so that the pull block 21 pulls the traction belt 4 to be wound, and the winding length of the traction belt 4 is greater than the moving distance of the driving component 3, thereby realizing the stroke amplification function when the traction belt 4 is wound; the driving component 3 moves toward the direction away from the pull block 21, and the driving component 3 drives the pull block 21 to reset along the length direction of the guide plate 231 through the connecting rod 22, so that the pull block 21 pulls the traction belt 4 to be unwound, and the unwinding length of the traction belt 4 is greater than the moving distance of the driving component 3, thereby realizing the stroke amplification function when the traction belt 4 is unwound.

The traction belt 4 passes through the pull block 21 in each group of connecting rod structures 2 in sequence, and one end of each group of connecting rods 22 is respectively rotatably connected to the driving assembly 3, so that the driving assembly 3 can drive the two connecting rod structures 2 to move at the same time. The guide plates 231 in the two groups of connecting rod structures 2 are arranged in parallel, and the two first sleeves 5 in the two groups of connecting rod structures 2 are arranged in an upper and lower stack on the first sleeve column 31. When the driving assembly 3 moves in the direction close to the pull block 21, the driving assembly 3 drives the two pull blocks 21 to move in opposite directions through the two connecting rods 22, thereby further improving the degree of stroke amplification.

[0113] The implementation principle of a connecting rod type stroke amplification mechanism for a cup lid in Example 2 of the present application is as follows: the driving component 3 drives the two pulling blocks 21 to move in opposite directions respectively through the two connecting rods 22 in the two sets of connecting rod structures 2, and the two pulling blocks 21 simultaneously drive the traction belt 4 to reel in or unreel, which is conducive to further amplifying the stroke.

A total of six pull blocks 21 in the three groups of connecting rod stroke amplification units 20 synchronously reel in the traction belt 4, thereby amplifying the degree of stroke amplification and facilitating the storage of the traction belt 4 after reeling.
