[0028] In the existing coffee machine structure, most of them use movable pins to limit the handle. The movable pins increase the parts cost and assembly cost of the coffee machine, and also increase the complexity of the coffee machine structure.
[0029] Based on the above reasons, an embodiment of the present application provides a handle limiting structure, including a handle connecting rod, an intermediate connecting rod and a seat connecting rod, the first end of the handle connecting rod is rotatably connected to the first rotating shaft, the second end of the handle connecting rod is hinged to the first end of the intermediate connecting rod, the second end of the intermediate connecting rod is hinged to the first end of the seat connecting rod, the second end of the seat connecting rod is rotatably connected to the second rotating shaft, and a handle is provided on the handle connecting rod; when the handle is rotated from a pressed state to a non-pressed state, the handle connecting rod rotates along a first direction to pass through the dead point position of the handle connecting rod and the intermediate connecting rod; when the handle is rotated from a non-pressed state to a pressed state, the handle connecting rod rotates along a direction opposite to the first direction to pass through the dead point position of the handle connecting rod and the intermediate connecting rod. In the embodiment of the present application, when the handle rotates from a pressed state to a non-pressed state, the intermediate connecting rod needs to rotate along a first direction to pass through the dead point positions of the handle connecting rod and the intermediate connecting rod, so that the handle can increase the resistance to automatic falling of the handle through the dead point limiting action of the connecting rod mechanism in the non-pressed state, thereby effectively avoiding the free fall of the handle, simplifying the structure for preventing the handle of the coffee machine from falling, reducing the parts cost and assembly cost of the coffee machine, and reducing the structural complexity of the coffee machine.
[0030] In some scenarios, a handle limiting structure of an embodiment of the present application can be applied to a capsule coffee machine, which can simplify the structure of the coffee machine to prevent the handle from falling, reduce the parts cost and assembly cost of the coffee machine, and reduce the structural complexity of the coffee machine.
[0031] A handle limiting structure provided in an embodiment of the present application is described in detail below with reference to specific examples.
[0032] Figure 1 A schematic diagram of a three-dimensional exploded structure of a handle limit structure provided in an embodiment of the present application. Figure 2 A schematic diagram of the internal structure of a handle limit structure provided in an embodiment of the present application, Figure 3 for Figure 2 A local structural diagram of a handle limit structure at A, as shown in FIG. Figures 1 to 3 As shown, the handle limiting structure includes a handle connecting rod 1, an intermediate connecting rod 2 and a seat connecting rod 3. The first end of the handle connecting rod 1 is rotatably connected to the first rotating shaft 41, the second end of the handle connecting rod 1 is hinged to the first end of the intermediate connecting rod 2, the second end of the intermediate connecting rod 2 is hinged to the first end of the seat connecting rod 3, the second end of the seat connecting rod 3 is rotatably connected to the second rotating shaft 42, and a handle 5 is provided on the handle connecting rod 1.
[0033] like Figure 1 As shown, the handle limiting structure includes a handle connecting rod 1, an intermediate connecting rod 2 and a seat connecting rod 3, and the handle connecting rod 1, the intermediate connecting rod 2 and the seat connecting rod 3 are connected end to end in sequence to form a connecting rod mechanism, and the working state of the brewing head assembly of the coffee machine is controlled by the connecting rod mechanism composed of the handle connecting rod 1, the intermediate connecting rod 2 and the seat connecting rod 3.
[0034] like Figure 1 As shown, the first end of the handle link 1 is rotatably connected to the first rotating shaft 41, the second end of the handle link 1 is hinged to the first end of the intermediate link 2, the second end of the intermediate link 2 is hinged to the first end of the seat body link 3, and the second end of the seat body link 3 is rotatably connected to the second rotating shaft 42. A handle 5 is provided on the handle link 1. When the handle 5 rotates, it drives the handle link 1 to rotate, and then the working state of the connecting rod mechanism can be controlled by rotating the handle 5.
[0035] like Figure 1 As shown, Figure 1 The schematic diagram of the three-dimensional exploded structure of the corresponding handle 5 in the pressed state is as follows: Figure 2 As shown, Figure 2 A schematic diagram of the three-dimensional decomposition structure corresponding to the handle 5 in the unpressed state. When the handle 5 rotates from the pressed state to the unpressed state, the handle connecting rod 1 rotates along the first direction to pass the dead point position of the handle connecting rod 1 and the intermediate connecting rod 2, wherein the dead point position of the handle connecting rod 1 and the intermediate connecting rod 2 corresponds to the colinear position of the handle connecting rod 1 and the intermediate connecting rod 2.
[0036] In the connecting rod mechanism composed of the handle connecting rod 1, the intermediate connecting rod 2 and the seat connecting rod 3, when the handle connecting rod 1 rotates beyond the colinear position of the handle connecting rod 1 and the intermediate connecting rod 2, the handle connecting rod 1 needs to overcome a greater resistance. Therefore, when the handle 5 is in a non-pressed state and the handle 5 tends to fall due to the influence of gravity, the handle limiting structure can prevent the handle 5 from falling under the action of gravity.
[0037] like Figure 3 As shown, when the user presses down the handle 5, the handle 5 is forced to rotate from the unpressed state to the pressed state, and the handle connecting rod 1 rotates in the opposite direction of the first direction to pass the dead point position of the handle connecting rod 1 and the middle connecting rod 2, thereby enabling the handle 5 to be pressed down smoothly.
[0038] like Figure 3 As shown, the collinear position of the handle link 1 and the intermediate link 2 corresponds to Figure 3 The dead point line formed by the collinearity of the handle link 1 and the middle link 2 in the figure, when the handle 5 is in the unpressed state or the pressed state, the hinge points of the handle link 1 and the middle link 2 are respectively located at the upper and lower sides of the dead point line. When the handle 5 is in the unpressed state, the hinge point of the handle link 1 and the middle link 2 is above the dead point line; when the handle 5 is in the pressed state, the hinge point of the handle link 1 and the middle link 2 is below the dead point line.
[0039] The beneficial effect brought about by the above implementation method is that the dead point limit principle of the connecting rod mechanism can be used to limit the rotation of the handle connecting rod and the intermediate connecting rod, thereby preventing the handle from falling freely.
[0040] In some implementations, when the handle 5 is in a non-pressed state, the angle between the handle link 1 and the intermediate link 2 is between 170° and 180°.
[0041] like Figure 3 As shown, the angle between the handle link 1 and the intermediate link 2 is α, and the value range of α is 170° to 180°. By setting the handle 5 in the non-pressed state to the corresponding angle between the handle link 1 and the intermediate link 2 between 170° and 180°, it can be ensured that the handle 5 is stably limited near the dead point position of the handle link 1 and the intermediate link 2, thereby ensuring the stability of the handle 5 in the non-pressed state.
[0042] The beneficial effect brought about by the above implementation method is that the stability of the handle in the non-pressed state is improved, thereby improving the user experience of the coffee machine.
[0043] In some implementations, when the handle 5 is in a non-pressed state, the second end of the handle connecting rod 1 and the second end of the seat connecting rod 3 are locked and positioned with each other through the locking structure 6 .
[0044] like Figure 3 As shown, structurally, the second end of the handle connecting rod 1 and the second end of the seat connecting rod 3 are correspondingly provided with a locking structure 6, and the locking structure 6 is used to further improve the stability of the handle 5 in the non-pressed state.
[0045] like Figure 3 As shown, when the handle 5 is in an unpressed state, the second end of the handle connecting rod 1 and the second end of the seat connecting rod 3 are locked and positioned with each other through the locking structure 6, thereby increasing the resistance of the handle 5 to falling under the action of gravity in the unpressed state, thereby improving the stability of the handle 5 in the unpressed state.
[0046] The beneficial effect brought about by the above implementation method is that it can increase the resistance of the handle to falling under the action of gravity when it is not pressed down, and improve the stability of the handle when it is not pressed down.
[0047] In some implementations, the locking structure 6 includes a ridge 61 and a groove 62 that can engage with each other, the ridge 61 is provided at the second end of the handle connecting rod 1, and the groove 62 is provided at the second end of the seat connecting rod 3. Alternatively, the ridge 61 is provided at the second end of the seat connecting rod 3, and the groove 62 is provided at the second end of the handle connecting rod 1.
[0048] Structurally, the locking structure 6 includes a ridge 61 and a groove 62 that can engage with each other, so that the handle connecting rod 1 and the intermediate connecting rod 2 can be positioned by engaging with each other.
[0049] Figure 4 A schematic diagram of a three-dimensional structure of a handle connecting rod provided in an embodiment of the present application. Figure 5 A three-dimensional structural diagram of a seat body connecting rod provided in an embodiment of the present application is shown in FIG. Figure 4 and Figure 5 As shown, the ridge 61 is provided at the second end of the handle connecting rod 1, and the groove 62 is provided at the second end of the seat connecting rod 3. Figure 3 As shown, when the handle 5 is in a non-pressed state, the second end of the handle connecting rod 1 and the second end of the seat connecting rod 3 are locked and positioned with each other through the locking structure 6 .
[0050] Optionally, the ridge 61 may also be provided at the second end of the seat connecting rod 3 , and the groove 62 may also be provided at the second end of the handle connecting rod 1 . The embodiment of the present application does not limit the positions of the ridge 61 and the groove 62 .
[0051] The beneficial effect brought about by the above implementation method is that the positions of the handle connecting rod and the intermediate connecting rod can be positioned by the mutual engagement of the convex ridges and the grooves.
[0052] In some implementations, the intermediate connecting rod 2 includes a curved section 21 forming an arc-shaped structure. When the handle 5 is in an unpressed state, the curved section 21 fits against the outer side wall of the second end of the seat connecting rod 3 .
[0053] like Figure 1 and Figure 3 As shown, structurally, the middle connecting rod 2 includes a bending section 21 forming an arc structure, and the bending section 21 is used to make way for the end of the seat connecting rod 3. When the handle 5 is in an unpressed state, the bending section 21 and the outer side wall of the second end of the seat connecting rod 3 fit together, thereby improving the compactness of the coffee machine structure.
[0054] The beneficial effect brought about by the above implementation method is that the bent section can give way to the end of the seat body connecting rod, thereby improving the compactness of the coffee machine structure.
[0055] In some implementations, a connecting shaft 7 is hinged on the hinge shaft between the second end of the intermediate connecting rod 2 and the first end of the seat connecting rod 3 through a connecting rod, and the connecting shaft 7 is used to connect to the brewing head assembly of the coffee machine.
[0056] like Figure 1 As shown, in order to control the brewing head assembly of the coffee machine, a connecting shaft 7 is hinged on the hinge shaft between the second end of the intermediate connecting rod 2 and the first end of the base connecting rod 3 through a connecting rod, and the connecting shaft 7 is used to connect the brewing head assembly of the coffee machine.
[0057] The beneficial effect brought about by the above implementation method is that it is easy to control the brewing component of the coffee machine and improves the structural compactness of the coffee machine.
[0058] In some implementations, a mounting hole 11 for mounting the handle 5 is provided on the handle connecting rod 1 .
[0059] like Figure 1 As shown, the handle connecting rod 1 is provided with a mounting hole 11 for mounting the handle 5 , and the handle 5 can be inserted into the mounting hole 11 during assembly.
[0060] In some implementations, there are two intermediate connecting rods 2 , and the two intermediate connecting rods 2 are respectively connected to the two sides of the handle connecting rod 1 and the seat connecting rod 3 .
[0061] Structurally, the hinge points of the two intermediate links 2 and the handle link 1 and the seat link 3 are staggered, which improves the compactness of the connection between the handle link 1, the seat link 3 and the intermediate link 2, and improves the compactness and stability of the handle limit structure.
[0062] The embodiment of the present application also provides another handle limiting structure, which includes a handle connecting rod 1, an intermediate connecting rod 2 and a seat connecting rod 3. The first end of the handle connecting rod 1 is rotatably connected to the first rotating shaft 41, the second end of the handle connecting rod 1 is hinged to the first end of the intermediate connecting rod 2, the second end of the intermediate connecting rod 2 is hinged to the first end of the seat connecting rod 3, the second end of the seat connecting rod 3 is rotatably connected to the second rotating shaft 42, and a handle 5 is provided on the handle connecting rod 1. When the handle 5 is in a non-pressed state, the second end of the handle connecting rod 1 and the second end of the seat connecting rod 3 are mutually locked and positioned by a locking structure 6.
[0063] The difference from the above-mentioned handle limiting structure is that the present handle limiting structure only locks and positions the second end of the handle connecting rod 1 and the second end of the seat connecting rod 3 with each other through the locking structure 6. The locking structure 6 can lock and limit the second end of the handle connecting rod 1 and the second end of the seat connecting rod 3, thereby preventing the handle from falling freely under the action of gravity.
[0064] Structurally, the locking structure 6 in the embodiment of the present application may be the same as the structure of the above-mentioned locking structure 6, which will not be described in detail here.
[0065] The embodiment of the present application further provides a coffee machine, which includes any of the handle limiting structures described above. The coffee machine simplifies the structure of the coffee machine to prevent the handle from falling, reduces the parts cost and assembly cost of the coffee machine, and reduces the structural complexity of the coffee machine through the handle limiting structure.
[0066] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
