Technical Field

[0001] The utility model relates to a kitchen utensil, in particular to a knife seat switching mechanism for a vegetable cutter which can cut and shred vegetables. Background Art

[0002] A grater is an appliance used to grate fruits and vegetables. A traditional grater includes a rubbing board with grating holes on the rubbing hole panel. This plate-type grater is used to grate food materials such as radish. The length of the radish shredded by the plate-type grater is generally short because the plate-type grater can only grate straight shreds for food materials. Therefore, the length of the radish shreds is always shorter than the length of the radish before grating. Generally, the length of the radish shreds is only one-third of the length of the radish, which cannot meet the needs of users.

[0003] Therefore, a rotary vegetable cutter capable of shredding appears on the market, such as a Chinese utility model patent "A grater" with patent number ZL201721226959.2 (publication number CN208319084U), which discloses such a grater, including a main board and a side board arranged along the outer edge of the main board, a plug-in column is arranged in the middle of the main board, an opening and a blade are arranged on the main board, the blade edge is located at the opening and is arranged radially with the plug-in column as the center, the blade edge is higher than the upper plane of the main board, a discharge port is formed between the blade edge and the opening, a toothed knife hole is arranged on the main board on one side of the discharge port, a shredder device is arranged below the toothed knife hole, and the shredder device is controlled by a control device to extend out of the toothed knife hole or reset.

[0004] The aforementioned control mechanism requires three buttons to control, resulting in a larger overall volume of the structure, which in turn causes the volume of the entire spiral vegetable cutter to increase accordingly. In addition, there are many parts involved, and the complex structure is not conducive to assembly. Summary of the invention

[0005] The technical problem to be solved by the present utility model is to provide a more compact and reasonable knife seat switching mechanism for a vegetable cutter in view of the above-mentioned current situation of the prior art.

[0006] The technical solution adopted by the present utility model to solve the above technical problem is as follows: A knife seat switching mechanism for a vegetable cutter, including adjacent first and second knife seats. The first and second knife seats are both provided with a plurality of blades extending upward. The first knife seat is fixed with a first push rod extending downward, and the second knife seat is fixed with a second push rod extending downward. The first push rod and the second push rod can only move up and down. It is characterized in that: It further includes a driving block that can reciprocate horizontally. The driving block can contact the lower ends of the first push rod and the second push rod. The driving block has a right driving surface that gradually slopes downward from right to left and a left driving surface that gradually slopes downward from left to right. There is a concave portion between the right driving surface and the left driving surface. The left driving surface has a notch. When the driving block is in the zero position, the lower ends of the first push rod and the second push rod both sink into the concave portion, then the first knife seat and the second knife seat are in the low position; when the driving block moves horizontally from the zero position from right to left, the right driving surface simultaneously acts on the lower ends of the first push rod and the second push rod and pushes them both upward; when the driving block moves horizontally from the zero position from left to right, the left driving surface can only act on the first push rod and push it upward, while the second push rod slides in the notch.

[0007] Further improvement, the above-mentioned notch is a cutting plane on the side of the left driving surface. Ensure that the second push rod sliding along the notch will not move upward

[0008] To ensure that the first push rod and the second push rod are always in contact with the driving block, the above-mentioned first push rod and second push rod are both provided with springs that keep them in a downward moving trend. Preferably, the springs are compression springs. Under the action of the springs, when the lower ends of the first push rod and the second push rod move to the concave portion, the first and second push rods drive the first knife seat and the second knife seat to move down to the lowest position.

[0009] To ensure that the first push rod and the second push rod can only move up and down, the above-mentioned first push rod and second push rod are respectively constrained in vertically arranged first chutes.

[0010] To ensure that the movement of the driving block can better drive the first push rod and the second push rod to move up and down, the lower ends of the first push rod and the second push rod are both provided with push heads. Each of the push heads has a right inclined surface that slidably cooperates with the right driving surface. In this way, the right driving surface can act on the first push rod and the second push rod simultaneously, and the setting of the inclined surface is more beneficial.

[0011] Preferably, the push head at the lower end of the first push rod has a left inclined surface that slidably cooperates with the left driving surface. Since the left driving surface generally does not act on the second push rod, the second push rod generally does not have a left inclined surface.

[0012] As an improvement, the above-mentioned driving block has a left high position and a right high position, both of which are planes. When the driving block translates from the zero position from right to left, the right driving surface can push the lower ends of the first push rod and the second push rod to the right high position. When the driving block translates from the zero position from left to right, the left driving surface can only push the first push rod to the left high position. This structure enables the first tool holder and the second tool holder to be in plane contact both when they are in the low position and the high position, avoiding the driving block being driven to move passively when the first tool holder and the second tool holder are under pressure, and the positioning is more reliable.

[0013] To ensure that the driving block only slides horizontally within a preset track, the above-mentioned driving block is installed in a second chute, and a push knob is arranged below the chute and fixed to the driving block.

[0014] To better cooperate the tool holder switching mechanism with the vegetable cutter and ensure that the first tool holder and the second tool holder only move up and down, the above-mentioned first tool holder and the second tool holder are constrained within the base body. The base body has an annular wall and a partition plate located within the annular wall. A plug post extending upward is provided in the middle of the partition plate. An opening and a main blade are provided on the partition plate. The cutting edge of the main blade is located at the opening. The cutting edge of the main blade is arranged radially with the plug post as the center. The cutting edge of the main blade is higher than the upper end surface of the partition plate so as to form a discharge port between it and the opening. A plurality of blade holes for the blade to extend or retract are provided on the partition plate.

[0015] For the convenience of assembly, a concave cavity with an upward opening is provided in the above-mentioned base body. The partition plate covers the mouth end of the concave cavity. The second chute is arranged within the concave cavity. The operating end of the push knob penetrates through the bottom surface of the concave cavity. Moreover, the second chute is located at the bottom of the first chute. An installation seat accommodated in the concave cavity is fixed on the partition plate. The first chute is arranged within the installation seat (10). The first tool holder and the second tool holder are installed within the installation seat. During installation, first install the switching mechanism as a whole onto the partition plate, and then install the partition plate onto the base body, which is more convenient for installation.

[0016] Compared with the prior art, the advantages of the present utility model are as follows: This driving mechanism only needs to drive a driving block to move horizontally back and forth to make the first tool rest and / or the second tool rest move up and down; and it can realize the switching of three states. The first state (zero position state), the lower ends of the first push rod and the second push rod both sink into the recess, the first tool rest and the second tool rest are in the low position, so the blades on both tool rests shrink down; the second state, the driving block translates from the zero position from right to left, the driving block simultaneously pushes the first push rod and the second push rod upward, that is, both the first tool rest and the second tool rest move up, so that the blades on both tool rests extend upward; the third state, the driving block translates from the zero position from left to right, the driving block only pushes the first push rod upward, and the second push rod slides in the notch, that is, only the first tool rest moves up, and only the blade on the first tool rest extends upward, and the second tool rest remains in the low position. This switching mechanism involves fewer components, and only needs to drive one driving block to act to complete the switching, and the structure is more reasonable.
