Description

Technical Field

[0001] The utility model relates to the technical field of juice extraction, in particular to a juice extractor. Background Art

[0002] In the prior art, a sugarcane juicer includes a mounting member, a drive assembly, a first squeezing wheel and a second squeezing wheel. The first squeezing wheel and the second squeezing wheel are both rotatably connected to the mounting member. The first squeezing wheel and the second squeezing wheel are spaced apart so that an input channel, a gap and an output channel that are sequentially connected are formed between the first squeezing wheel and the second squeezing wheel. The drive assembly is used to drive the first squeezing wheel to rotate in a first direction and to drive the second squeezing wheel to rotate in a second direction. By placing the end of the sugarcane stem into the input channel, the first squeezing wheel and the second squeezing wheel jointly guide the sugarcane stem through the gap, and the first squeezing wheel and the second squeezing wheel respectively squeeze the interfering stems to separate the sugarcane bagasse from the sugarcane juice, so as to facilitate users to drink the sugarcane juice, thereby achieving the effect of promoting salivation and quenching thirst, replenishing water and energy; wherein the first direction is opposite to the second direction.

[0003] However, in the process of implementing the present invention, the inventors discovered that the cross-section of the input channel gradually increases from the input channel toward the output channel. When the sugarcane stalks are placed in the input channel, the ends of the sugarcane stalks need to be cut into tapering shapes so that the first and second squeezing wheels can quickly guide the sugarcane stalks into the gap, resulting in very low efficiency in extracting sugarcane juice.

The terms "vertical", "horizontal", "left", "right" and similar expressions used in this specification are for illustrative purposes only.

[0027] Unless otherwise defined, all technical and scientific terms used in this specification have the same meanings as those commonly understood by those skilled in the art to which this utility model belongs. The terms used in this specification and in the description of this utility model are only for the purpose of describing specific embodiments and are not intended to limit the utility model. The term "and / or" used in this specification includes any and all combinations of one or more of the relevant listed items.

[0028] The utility model provides a juicer 100, which is used to extract juice from an external object. For example, the juicer 100 separates sugarcane juice from sugarcane stalks for drinking by users, thereby quenching thirst and replenishing water and energy.

[0029] See also Figure 1-Figure 3The juicer 100 includes a mounting member 10, a first ratchet 20, a first squeezing wheel 30, a second squeezing wheel 40, and a drive assembly (not shown). The first squeezing wheel 30, the first ratchet 20, and the second squeezing wheel 40 are rotatably connected to the mounting member 10. The first ratchet 20, the first squeezing wheel 30, and the second squeezing wheel 40 are spaced apart from each other so that the lines connecting the first squeezing wheel 30 and the first ratchet 20, the line connecting the first ratchet 20 and the second squeezing wheel 40, and the line connecting the second squeezing wheel 40 and the first squeezing wheel 30 are connected end to end to form a triangular structure. The drive assembly is connected to the first ratchet 20, the first squeezing wheel 30, and the second squeezing wheel 40. The drive assembly is configured to drive the first squeezing wheel 30 to rotate in a first direction R1 and the first ratchet 20 and the second squeezing wheel 40 to rotate in a second direction R2. When the driving assembly drives the first ratchet 20, the first squeezing wheel 30 and the second squeezing wheel 40 to rotate, the first ratchet 20 and the first squeezing wheel 30 jointly guide the external object to the squeezing gap 100a between the first squeezing wheel 30 and the second squeezing wheel 40, and the first squeezing wheel 30 and the second squeezing wheel 40 jointly squeeze the external object so that the juice of the external object is separated.

[0030] For the above mounting part 10, please refer to Figure 1 The mounting member 10 is a box-type structure. The mounting member 10 is provided with a feeding port 10a, and the gap between the first ratchet wheel 20 and the first extrusion wheel 30 corresponds to the feeding port 10a.

[0031] For the first ratchet 20 mentioned above, see Figure 2-Figure 3The first ratchet wheel 20 includes a first wheel portion 21 and a first ratchet portion 22. The first wheel portion 21 is rotationally connected to the mounting member 10, and the first ratchet portion 22 is fixed to the first wheel portion 21 along a circumferential direction of the first wheel portion 21. The mounting member 10, the first wheel portion 21, and the first ratchet portion 22 collectively enclose a first accommodating slot 20b. When the drive assembly drives the first ratchet wheel 20 to rotate in the second direction R2, the first accommodating slot 20b is opposite to the first pressing wheel 30, and part of the outer surface of the first pressing wheel 30 covers part of the slot of the first accommodating slot 20b, so that the first accommodating gap 20c is formed between the first ratchet wheel 20 and the first pressing wheel 30, and the first accommodating gap 20c is used to accommodate external objects, such as the stems of sugarcanes. When the first ratchet wheel 20 continues to rotate in the second direction R2, the first ratchet portion 22 of the first ratchet wheel 20 gradually approaches the first pressing wheel 30 until the first ratchet portion 22 contacts the external object, at which time the first pulling gap 20d is formed between the first ratchet wheel 20 and the first pressing wheel 30. As the first ratchet wheel 20 rotates, the first ratchet portion 22 gradually approaches the second pressing wheel 40, the first ratchet portion 22 pulls the external object towards the second pressing wheel 40, and the first pulling gap 20d allows the external object to pass. It can be understood that the first accommodating gap 20c and the first pulling gap 20d are switched cyclically. When the first accommodating gap 20c changes to the first pulling gap 20d, the first ratchet portion 22 moves towards the external object or towards the first pressing wheel 30 until the first ratchet portion 22 contacts the external object. When the first pulling gap 20d changes to the first accommodating gap 20c, the first ratchet portion 22 pulls the external object to the pressing gap 100a for the first pressing wheel 30 and the second pressing wheel 40 to jointly press the external object. It should be noted that the first direction R1 is opposite to the second direction R2. It should be noted that the interval of the first accommodating gap 20c is larger than the outer diameter of the external object, so that the external object can be accommodated in the first accommodating gap 20c. The interval of the first pulling gap 20d is usually smaller than the outer diameter of the external object. When the first ratchet portion 22 approaches the first pressing wheel 30 until the first ratchet portion 22 contacts the external object and gradually clamps the external object, the first ratchet portion 22 extrudes the outer surface of the external object and forms a groove, so that the first ratchet portion 22 more stably pulls the external object to move.

[0032] The end of the first ratchet portion 22 away from the first wheel portion 21 is provided with a first anti-slip structure 20a, which reduces the risk of slipping between the first ratchet wheel 20 and the external object when the first ratchet portion 22 extrudes the external object.

[0033] In some embodiments, the number of first ratchet portions 22 is at least two, and the first ratchet portions 22 are arranged at intervals along the circumferential direction of the first wheel portion 21. For example, the number of first ratchet portions 22 is five, and the five first ratchet portions 22 are equidistantly arranged along the circumferential direction of the first wheel portion 21.

[0034] In some embodiments, the first squeezing wheel 30 is provided with a second anti-slip structure 30a, which reduces the risk of the first squeezing wheel 30 and the external object slipping when the first ratchet wheel 20 and the first squeezing wheel 30 squeeze the external object together.

[0035] In some embodiments, please refer to Figure 1 The juicer 100 also includes a second ratchet 50, which is rotatably connected to the mounting member 10. The first ratchet 20 and the second squeezing wheel 40 are diagonally arranged. The second ratchet 50 is diagonally arranged to the first squeezing wheel 30, and the second ratchet 50 is connected to the driving assembly. The driving assembly can drive the second ratchet 50 to rotate along the second direction R2. The second ratchet 50 is used to receive external objects output from the gap between the first ratchet 20 and the first squeezing wheel 30, and pull the external objects to be transported to the squeezing gap 100a.

[0036] See also Figure 2-Figure 3The second ratchet 50 includes a second wheel portion 51 and a second ratchet portion 52. Along the circumferential direction of the second wheel portion 51, the second ratchet portion 52 is fixed to the second wheel portion 51, and the second wheel portion 51 is rotatably connected to the mounting member 10. The mounting member 10, the second ratchet portion 52 and the second wheel portion 51 are jointly enclosed to form a second receiving groove 50a. The second wheel portion 51 is connected to the driving assembly, and the second wheel portion 51 is used to be driven by the driving assembly to rotate the second ratchet 50 along the second direction R2. When the second ratchet 50 rotates along the second direction R2, the second receiving groove 50a is opposite to the first extrusion wheel 30 and the second extrusion wheel 40. The first extrusion wheel 30 and the second extrusion wheel 40 jointly cover a portion of the notch of the second receiving groove 50a, so that the second receiving groove 50a and the first extrusion wheel 30 and the second extrusion wheel 40 are jointly enclosed to form a second receiving gap 50b. The second receiving gap 50b is used to receive external objects transported in the gap between the first extrusion wheel 30 and the first ratchet 20. When the second ratchet 50 continues to rotate along the second direction R2, the second receiving groove 50a is opposite to the first extrusion wheel 30 and the second extrusion wheel 40. As the second ratchet wheel 50 rotates, the second ratchet portion 52 of the second ratchet wheel 50 gradually moves toward the first and second extrusion wheels 30, 40 until the second ratchet portion 52 contacts the external object. At this point, a second pulling gap 50c is formed between the second ratchet wheel 50 and the first and second extrusion wheels 30, 40. As the second ratchet wheel 50 rotates, the second ratchet portion 52 gradually moves toward the first and second extrusion wheels 30, 40, pulling the external object toward the extrusion gap 100a between the first and second extrusion wheels 30, 40. It can be understood that a cyclically switching second accommodating gap 50b and second pulling gap 50c are formed between the second ratchet wheel 50 and the first and second extrusion wheels 30, 40. When the second accommodating gap 50b changes to the second pulling gap 50c, the second ratchet portion 52 moves toward the external object until the second ratchet portion 52 contacts the external object. When the second pulling gap 50c changes to the second accommodating gap 50b, the second ratchet portion 52 pulls the external object toward the extrusion gap 100a.

[0037] The end of the second ratchet portion 52 facing away from the second wheel portion 51 is provided with a bearing surface 50e. When the second ratchet portion 52 squeezes an external object, the external object is easily broken, and part of the external object is discharged from the gap between the second ratchet wheel 50 and the second squeezing wheel 40. For example, a stalk of sugarcane is easily broken, causing part of the stalk to separate from the main body. The bearing surface 50e can support the external object. The longer the bearing surface 50e is along the direction of rotation of the second ratchet wheel 50, the more residual external object can be carried, reducing the amount of residual object that falls into the second receiving groove 50a. It should be noted that when the residual object falls into the second receiving groove 50a, as the second receiving groove 50a containing the residual object is at the bottom, the residual object falls, resulting in material waste.

[0038] In some embodiments, the number of the second protrusions 52 is at least two, and the second protrusions 52 are arranged at intervals along the circumferential direction of the first wheel 21. Exemplarily, the number of the second protrusions 52 is three, and the three second protrusions 52 are arranged at equal intervals along the circumferential direction of the second wheel 51.

[0039] In some embodiments, the second protrusions 52 are provided with a third anti-slip structure, which reduces the risk of slippage between the second ratchet wheel 50 and the external object when the second ratchet wheel 50 is jointly pressed against the external object by the first pressing wheel 30 and the second pressing wheel 40.

[0040] In some embodiments, the second pressing wheel 40 is provided with a fourth anti-slip structure 40a, which reduces the risk of slippage between the second pressing wheel 40 and the external object when the first pressing wheel 30 and the second pressing wheel 40 are jointly pressed against the external object.

[0041] In some embodiments, the juicer 100 further comprises a filter screen (not shown in the figure), which is arranged on the mounting member 10, and the first pressing wheel 30, the first ratchet wheel 20, and the second pressing wheel 40 are located below the filter screen, and the filter screen is used to filter impurities in the juice of the external object.

[0042] For the above-mentioned driving assembly, the driving assembly is an electric motor.

[0043] In the embodiment of the present application, the mounting member 10, the first ratchet 20, the first extruding wheel 30, the second extruding wheel 40 and the driving assembly, the first extruding wheel 30 is rotatably connected to the mounting member 10, the first ratchet 20 includes a first wheel portion 21 and a first ratchet portion 22, the first wheel portion 21 is rotatably connected to the mounting member 10, the first ratchet portion 22 is fixed to the first wheel portion 21, the second extruding wheel 40 is rotatably connected to the mounting member 10, the second extruding wheel 40 is spaced apart from the first extruding wheel 30 and the first ratchet 20, and an extrusion gap 100a is formed between the first extruding wheel 30 and the second extruding wheel 40, the driving assembly is connected to the first extruding wheel 30, the first ratchet 20 and the second extruding wheel 40, and the driving assembly is used to drive the first extruding wheel 30 to rotate along the first direction R1, and the first ratchet 20 and the second extruding wheel 40 to rotate along the second direction R2, so that the second extruding wheel 40 A first accommodating gap 20c and a first pulling gap 20d that are cyclically switched are formed between a ratchet 20 and the first extrusion wheel 30. The first accommodating gap 20c is used to accommodate external objects. When the first accommodating gap 20c changes to the first pulling gap 20d, the first ratchet portion 22 moves toward the external object until the first ratchet portion 22 contacts the external object. When the first pulling gap 20d changes to the first accommodating gap 20c, the first ratchet portion 22 pulls the external object to be transported to the extrusion gap 100a, so that the first extrusion wheel 30 and the first extrusion wheel 30 can jointly extrude the external object. Compared with the prior art, the gap formed between the first ratchet 20 and the first extrusion wheel 30 can guide and pull the external object to be transported to the extrusion gap 100a between the first extrusion wheel 30 and the second extrusion wheel 40, thereby eliminating the need to cut the external object into pieces and improving production efficiency.

[0044] It should be noted that the preferred embodiments of the present invention are given in the specification and drawings of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described in this specification. These embodiments do not serve as additional limitations on the content of the present invention. The purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive. In addition, the above-mentioned technical features continue to be combined with each other to form various embodiments not listed above, which are all considered to be within the scope of the description of the present invention; further, it is obvious to those skilled in the art that improvements or changes can be made based on the above description, and all such improvements and changes should fall within the scope of protection of the claims attached to the present invention.
