Description

Technical Field

[0001] This utility model relates to a food cutter that is particularly suitable for slicing or shredding food (such as potatoes), and more particularly to a blade holder adjustment mechanism for a food cutter. Background Technology

[0002] There are many patents related to food cutters used for slicing or shredding food (such as potatoes). The earliest patent is a Chinese utility model patent with patent number ZL201821293309.4 (publication number CN208629506U), which discloses a food cutter including a housing and a cutting mechanism. The housing has an inlet and an outlet. The cutting mechanism includes a cutting part and a push-pull part for controlling the reciprocating movement of the cutting part. The cutting part includes a sliding member, a first cutter, and multiple second cutters. The sliding member is slidably connected to the housing. Both the first and second cutters are located on the side of the sliding member near the inlet and are connected to the sliding member. The second cutter includes a first cutting group and a second cutting group. The first cutting group includes a first cutter holder, a second threaded member, and multiple first cutters. The second cutting group includes a second cutter holder, a second threaded member, and multiple second cutters. The second threaded member is specifically a threaded rod. Multiple first cutters are fixed on the first cutter holder, and multiple second cutters are fixed on the second cutter holder. The first and second cutter holders can be joined together. When joined, the first and second cutting blades are alternately positioned, and both can pass through the channel. Both the first and second cutter holders are slidably engaged with the sliding member, sliding towards or away from the channel. Both the first and second cutter holders are provided with threaded through holes. Two threaded rods pass through the lower surface of the sliding member and are rotatably connected to it. The two threaded rods are threadedly engaged with the two threaded through holes. Because the threaded rods are threadedly engaged with the threaded holes, when the threaded rods rotate clockwise, the first cutter holder can move upward along the sliding member, that is, the first cutter holder drives the first cutting blade to move towards the feed inlet, and the first cutting blade passes through the channel to cut the food. When the threaded rods rotate counterclockwise, the first cutting blade is located below the channel and cannot cut the food. The operation of the second cutter holder and the second cutting blade is the same as that of the first cutter holder.

[0003] However, the first and second tool holders in the aforementioned patent are operated independently via two separate threaded rods, which is inconvenient. Due to limited space, the two individual knobs can only be made very small, making operation laborious and inflexible. Furthermore, the two knobs also affect the appearance.

[0004] To address this, Chinese utility model patent ZL202020608724.5 (publication number CN211993100U) discloses an easily adjustable food cutter. When adjusting the thickness of the cut food, rotating a knob drives a drive rod. Because the drive rod has a helical flange, and the cutting plate has a fourth through hole that mates with the flange, the principle of the drive rod's rotation is similar to the engagement of a screw and nut. During the rotation of the drive rod, the cutting plate moves axially along the drive rod, thus allowing the cutting plate to slide along the housing. Controlling the cutting plate by rotating the drive rod eliminates the need to disassemble the housing, making operation convenient. When the knob is rotated, the second gear inside the knob meshes with the first gear, thereby driving the rotating component with the first gear to rotate. The rotating component then drives the drive rod to rotate, achieving the effect of driving the cutting plate to slide along the housing.

[0005] The aforementioned adjustment mechanism uses a special gear structure design to move the cutting plate (tool holder) by rotating two drive rods through a knob. However, this requires two gears, which are very small, making them inconvenient to manufacture and requiring high machining precision. Furthermore, due to their small size, the gears have low strength, resulting in poor transmission stability and easy damage.

[0006] In conclusion, both of the aforementioned tool holder adjustment mechanisms have certain shortcomings and can be further improved. Summary of the Invention

[0007] The technical problem to be solved by this utility model is to provide a more compact and reasonable structure, smoother transmission, and higher strength blade holder adjustment mechanism for a food cutter, in light of the above-mentioned existing technology.

[0008] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: the blade holder adjustment mechanism of the food cutter includes a housing, an adjustment knob, and adjacent first and second blade holders. A first drive shaft and a second drive shaft that can move along their own axial direction are inserted and constrained on the housing. The first blade holder is fixed to the lower end of the first drive shaft, and the second blade holder is fixed to the lower end of the second drive shaft. The first drive shaft is provided with a laterally protruding first drive post, and the second drive shaft is provided with a laterally protruding second drive post. The adjustment knob is rotatably mounted on the housing. The adjustment knob is provided with a transmission spiral groove that cooperates with the first and second drive posts. The first and second drive posts are placed in the transmission spiral groove. When the adjustment knob is rotated, the first and second drive posts can slide along the transmission spiral groove, thereby causing the first and second drive shafts to move relative to the housing along their own axial direction.

[0009] To enable the first and second drive shafts to move relative to the outer casing along their own axial direction, preferably, the transmission spiral groove is divided into three sections: an upper arc-shaped groove section, a middle transition arc-shaped groove section, and a lower arc-shaped groove section. The middle transition arc-shaped groove section connects the upper and lower arc-shaped groove sections. Thus, when the first and second drive columns slide along the transmission spiral groove, they can move up and down between the upper and lower arc-shaped groove sections via the middle transition arc-shaped groove section, thereby driving the first and second drive shafts to switch between upper and lower positions.

[0010] Furthermore, the adjustment knob has three positions according to its rotation angle: 0 degree position, first position, and second position.

[0011] In the 0-degree position, both the first and second drive columns are in the upper arc-shaped groove section, and both the first and second drive shafts are in the upper position.

[0012] In the first gear position, the first drive column is in the upper arc-shaped groove section, and the second drive column slides through the middle transition arc-shaped groove section to the lower arc-shaped groove section. The first drive shaft is in the upper position, and the second drive shaft is in the lower position.

[0013] In the second gear position, both the first drive column and the second drive column slide to the lower arc-shaped groove section via the intermediate transition arc-shaped groove section, and both the first drive shaft and the second drive shaft are in the lower position.

[0014] In the 0-degree setting, since both the first and second drive shafts are in the upper position, and neither the first nor the second cutter holder extends, the blades on both cutter holders cannot cut the food. In this setting, the food can be cut into slices. In the first setting, since the first drive shaft is in the upper position and the second drive shaft is in the lower position, the second cutter holder extends downwards, and the blades on the second cutter holder can cut the food into coarser shreds. In the second setting, since both the first and second drive shafts are in the lower position, and both the first and second cutter holders extend downwards, the blades on both cutter holders work together to cut the food into finer shreds.

[0015] To ensure the knob can be positioned at each gear when rotated, preferably, the adjustment knob is equipped with a positioning member held by a spring, and the surface of the outer casing has recesses corresponding to the three gear positions. When the adjustment knob is rotated to the corresponding gear position, the positioning member is positioned within the corresponding recess. Thus, when the adjustment knob is rotated to the corresponding gear position, frictional vibration is generated due to the positioning member entering the corresponding recess, increasing the feel of rotating the adjustment knob; and the spring-held positioning member increases the damping of the adjustment knob's rotation, further enhancing the feel of rotating the adjustment knob.

[0016] To determine the rotation direction of the adjustment knob during gear shifting, preferably, a first baffle is provided at the starting end of the upper arc-shaped groove segment; in the 0-degree gear position, the first baffle blocks the first driving column, and the first driving column can only rotate towards the middle transition arc-shaped groove segment; a second baffle is provided at the end of the lower arc-shaped groove segment; in the second gear position, the second baffle blocks the second driving column, and the second driving column can only rotate towards the middle transition arc-shaped groove segment.

[0017] Preferably, both the upper and lower arc-shaped groove segments have horizontal sections. This horizontal section locks the first and second driving columns when they are in the upper or lower arc-shaped groove segment, preventing them from sliding due to vibrations during food cutting.

[0018] As one configuration of the aforementioned tool holder adjustment mechanism, the adjustment knob has a top wall and a peripheral wall located below the top wall. The top wall is constrained on the outer shell and can rotate around its own axis. The peripheral wall can rotate together with the top wall. The first drive shaft and the second drive shaft are located within the space enclosed by the peripheral wall. The transmission spiral groove is located on the inner peripheral surface of the peripheral wall.

[0019] To facilitate the machining of the transmission helical groove on the inner circumferential surface of the peripheral wall, preferably, the top wall and the peripheral wall are two independent components. The top wall is rotatable and fitted onto the outer shell via screws. A rib groove insertion structure is provided between the top wall and the peripheral wall. Machining the top wall and the peripheral wall as two independent components allows for easier forming of the transmission helical groove on the inner circumferential surface of the peripheral wall, thereby reducing the machining difficulty of the adjustment knob.

[0020] As another configuration of the aforementioned tool holder adjustment mechanism, the adjustment knob has a top wall and a transmission column connected to the bottom surface of the top wall. The transmission column can rotate with the top wall. The transmission column is located between the first drive shaft and the second drive shaft. The transmission spiral groove is provided on the outer circumferential surface of the transmission column.

[0021] To facilitate the machining of the transmission helical groove on the outer circumference of the transmission column, preferably, the top wall and the transmission column are two independent components. The bottom surface of the top wall has a downwardly extending sleeve portion. The sleeve portion is fitted onto the boss of the outer shell, allowing it to rotate and constraining the outer shell. The transmission column is fitted onto the outer circumference of the sleeve portion, and a keyway structure is provided between the inner circumference of the transmission column and the outer circumference of the sleeve portion. Machining the top wall and the transmission column as two independent components allows for easier forming of the transmission helical groove on the outer circumference of the transmission column, thereby reducing the machining difficulty of the adjustment knob.

[0022] Compared with the prior art, the advantages of this utility model are as follows: This tool holder adjustment mechanism only requires one adjustment knob to move the first and second drive shafts along their own axes relative to the outer casing, thereby enabling the first and / or second tool holders to move up and down; it can also achieve three gear switching: 0 degree gear, both the first and second drive shafts are in the upper position, so neither the first nor the second tool holder extends; in the first gear, rotating the adjustment knob causes the second drive column to slide through the intermediate transition arc groove to the lower arc groove, the second drive shaft moves down while the first drive shaft remains in the upper position, so only the second tool holder extends downward; in the second gear, rotating the adjustment knob causes both the first and second drive columns to slide through the intermediate transition arc groove to the lower arc groove, the first and second drive shafts move down, so both the first and second tool holders extend downward. This tool holder adjustment mechanism involves fewer components, has a more compact and reasonable structure, and provides smoother transmission and higher strength. Attached Figure Description

[0037] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0038] Example 1

[0039] like Figures 1-7 As shown, the blade holder adjustment mechanism of the food cutter in this embodiment includes a housing 1, an adjustment knob 2, adjacent first blade holders 3 and second blade holders 4, and a first drive shaft 5 and a second drive shaft 6 that are interposed and constrained on the housing 1 and can move along their own axial direction. The first blade holder 3 is fixed to the lower end of the first drive shaft 5, and the second blade holder 4 is fixed to the lower end of the second drive shaft 6. Both the first drive shaft 5 and the second drive shaft 6 have rectangular cross-sections. The housing 1 has a first rectangular hole for guiding the first drive shaft 5 and a second rectangular hole for guiding the second drive shaft 6. The first drive shaft 5 has a side-protruding first drive post 51, and the second drive shaft 6 has a side-protruding second drive post 61. The adjustment knob 2 is rotatably mounted on the housing 1. The adjustment knob 2 has a transmission spiral groove 7 that cooperates with the first drive post 51 and the second drive post 61. The first drive post 51 and the second drive post 61 are placed in the transmission spiral groove 7. Rotating the adjustment knob 2 allows the first drive post 51 and the second drive post 61 to slide along the transmission spiral groove 7, thereby causing the first drive shaft 5 and the second drive shaft 6 to move relative to the housing 1 along their own axial direction. The tool holder adjustment mechanism only requires one adjustment knob 2 to drive the first drive shaft 5 and the second drive shaft 6 to move relative to the outer shell 1 along their own axis, so that the first tool holder 3 and / or the second tool holder 4 can move up and down. It involves few parts, has a compact and reasonable structure, and has smooth transmission and high strength.

[0040] See details Figure 2-4 In this embodiment, the adjustment knob 2 has a top wall 21 and a peripheral wall 22 located below the top wall 21. The top wall 21 is constrained on the outer shell 1 and can rotate around its own axis. The peripheral wall 22 can rotate together with the top wall 21. The first drive shaft 5 and the second drive shaft 6 are located within the space enclosed by the peripheral wall 22. The transmission spiral groove 7 is provided on the inner peripheral surface of the peripheral wall 22. Since it is difficult to form the transmission spiral groove 7 on the inner peripheral surface of the peripheral wall 22, in order to facilitate the forming of the transmission spiral groove 7, the top wall 21 and the peripheral wall 22 in this embodiment are two independent components. The top wall 21 is fitted onto the boss 12 of the outer shell 1 and can rotate and is constrained on the outer shell 1 by screws 9. A rib groove insertion structure is provided between the top wall 21 and the peripheral wall 22. In this embodiment, the transmission spiral groove 7 is divided into three sections: an upper arc-shaped groove section 7a, a middle transition arc-shaped groove section 7b, and a lower arc-shaped groove section 7c. In this embodiment, both the upper arc-shaped groove section 7a and the lower arc-shaped groove section 7c are horizontally arranged, with the upper arc-shaped groove section 7a located above the lower arc-shaped groove. The middle transition arc-shaped groove section 7b connects the upper arc-shaped groove section 7a and the lower arc-shaped groove section 7c together. As the adjustment knob 2 is rotated, the first driving column 51 and the second driving column 61 slide along the spiral groove 7 and can move up and down between the upper arc-shaped groove section 7a and the lower arc-shaped groove section 7c via the middle transition arc-shaped groove section 7b, thereby driving the first driving shaft 5 and the second driving shaft 6 to switch between the upper and lower positions.

[0041] See Figure 5-7 The adjustment knob 2 has three positions based on its rotation angle: 0 degree, first position, and second position. In the 0 degree position, as... Figure 5 As shown, the first driving column 51 and the second driving column 61 are both located in the upper arc-shaped groove section 7a, the first driving shaft 5 and the second driving shaft 6 are both in the upper position, the first blade holder 3 and the second blade holder 4 do not extend, and the blades provided on the first blade holder 3 and the second blade holder 4 cannot cut the food. In this state, the food can be cut into slices; in the first gear state, as Figure 6 As shown, the first driving column 51 is located in the upper arc-shaped groove section 7a, and the second driving column 61 slides through the intermediate transition arc-shaped groove section 7b to the lower arc-shaped groove section 7c. The first driving shaft 5 is in the upper position, and the second driving shaft 6 is in the lower position. The second blade holder 4 extends downward, and the blade on the second blade holder 4 can cut food into relatively coarse shreds. In the second gear state, as... Figure 7 As shown, the first driving column 51 and the second driving column 61 both slide to the lower arc-shaped groove 7c via the intermediate transition arc-shaped groove 7b. The first driving shaft 5 and the second driving shaft 6 are both in the lower position. The first cutter holder 3 and the second cutter holder 4 both extend downward. The blades provided on the first cutter holder 3 and the second cutter holder 4 are used together to cut food and cut the food into finer shreds.

[0042] In this embodiment, rotating the adjustment knob 2 clockwise allows the various gear positions to change sequentially in the order of 0-degree gear, first gear, and second gear. Rotating the adjustment knob 2 counterclockwise allows the gear positions to change sequentially in the order of second gear, first gear, and 0-degree gear. During gear adjustment, to determine the direction of rotation of the adjustment knob 2, a first baffle 71 is provided at the beginning of the upper arc-shaped groove segment 7a. In the 0-degree gear position, the first baffle 71 blocks the first driving column 51, allowing it to rotate only towards the intermediate transition arc-shaped groove segment 7b. Similarly, a second baffle 72 is provided at the end of the lower arc-shaped groove segment 7c. In the second gear position, the second baffle 72 blocks the second driving column 61, allowing it to rotate only towards the intermediate transition arc-shaped groove segment 7b.

[0043] Furthermore, to ensure that each gear position is correctly positioned when the knob is rotated, the adjustment knob 2 is equipped with a positioning member 8 held by a spring, and the surface of the outer casing 1 has recesses 11 corresponding to the three gear positions. When the adjustment knob 2 is rotated to the corresponding gear position, the positioning member 8 is positioned within the corresponding recess 11. Thus, when the adjustment knob 2 is rotated to the corresponding gear position, frictional vibration is generated due to the positioning member 8 entering the corresponding recess 11, increasing the feel of rotating the adjustment knob 2; and the spring-held positioning member 8 increases the damping of the rotation of the adjustment knob 2, further enhancing the feel of rotating the adjustment knob 2.

[0044] In summary, the adjustment method of the tool holder adjustment mechanism in this embodiment is as follows:

[0045] 0-degree position: The first drive column 51 is at the beginning of the upper arc-shaped groove segment 7a, and the second drive columns 61 are both at the end of the upper arc-shaped groove segment 7a. The first drive shaft 5 and the second drive shaft 6 are both in the upper position. (See attached image) Figure 5 Neither the first tool holder 3 nor the second tool holder 4 extends out;

[0046] To switch from the 0-degree setting to the first setting: Turn the adjustment knob 2 clockwise. The first drive column 51 slides from the beginning of the upper arc-shaped groove segment 7a to the end of the upper arc-shaped groove segment 7a. The second drive shaft 6 slides through the intermediate transition arc-shaped groove segment 7b to the beginning of the lower arc-shaped groove segment 7c. The first drive shaft 5 is in the upper position, and the second drive shaft 6 is in the lower position. See the first setting status for reference. Figure 6 The second tool holder 4 extends downwards;

[0047] To switch from the first gear to the second gear: Turn the adjustment knob 2 clockwise. The first drive shaft 5 slides through the intermediate transition arc-shaped groove 7b to the beginning of the lower arc-shaped groove 7c. The second drive column 61 slides from the beginning of the lower arc-shaped groove 7c to the end of the lower arc-shaped groove 7c. See the second gear position for details. Figure 7 Both the first tool holder 3 and the second tool holder 4 extend downwards;

[0048] To switch from the second gear to the first gear: Turn the adjustment knob 2 counterclockwise. The first drive shaft 5 slides through the intermediate transition arc-shaped groove 7b to the end of the upper arc-shaped groove 7a. The second drive column 61 slides from the end of the lower arc-shaped groove 7c to the beginning of the lower arc-shaped groove 7c. See the first gear position for reference. Figure 6 The first tool holder 3 retracts upwards, while the second tool holder 4 remains extended downwards;

[0049] To switch from the first gear to the 0-degree gear, turn the adjustment knob 2 counterclockwise. The first drive column 51 slides from the end of the upper arc-shaped groove 7a to the beginning of the upper arc-shaped groove 7a. The second drive shaft 6 slides through the intermediate transition arc-shaped groove 7b to the end of the upper arc-shaped groove 7a. See the 0-degree gear position for details. Figure 5 Both the first tool holder 3 and the second tool holder 4 retract upwards.

[0050] Example 2

[0051] like Figures 8-14 As shown, the structure of the blade holder adjustment mechanism of the food cutter in this embodiment is basically the same as that in Embodiment 1, with the difference being: Figure 9 As shown, the adjustment knob 2 in this embodiment has a top wall 21 and a transmission column 23 connected to the bottom surface of the top wall 21. The transmission column 23 can rotate together with the top wall 21. The transmission column 23 is located between the first drive shaft 5 and the second drive shaft 6. The transmission spiral groove 7 is provided on the outer peripheral surface of the transmission column 23. In order to facilitate the forming of the transmission spiral groove 7, the top wall 21 and the transmission column 23 are two independent parts. The bottom surface of the top wall 21 has a downwardly extending sleeve portion 24. The sleeve portion 24 is fitted on the boss 12 of the outer shell 1 and can rotate and be constrained on the outer shell 1. The transmission column 23 is fitted on the outer periphery of the sleeve portion 24, and a keyway structure is provided between the inner peripheral surface of the transmission column 23 and the outer peripheral surface of the sleeve portion 24.

[0052] The structure of the transmission spiral groove 7 in this embodiment is shown in the reference diagram. Figure 10-11 The transmission spiral groove 7 is divided into three sections: an upper arc-shaped groove section 7a, a middle transition arc-shaped groove section 7b, and a lower arc-shaped groove section 7c. In this embodiment, both the upper arc-shaped groove section 7a and the lower arc-shaped groove section 7c are horizontally arranged, with the upper arc-shaped groove section 7a located above the lower arc-shaped groove. The middle transition arc-shaped groove section 7b connects the upper arc-shaped groove section 7a and the lower arc-shaped groove section 7c together. As the adjustment knob 2 is rotated, the first driving column 51 and the second driving column 61 slide along the spiral groove 7 and can move up and down between the upper arc-shaped groove section 7a and the lower arc-shaped groove section 7c via the middle transition arc-shaped groove section 7b, thereby driving the first driving shaft 5 and the second driving shaft 6 to switch between the upper and lower positions.

[0053] In this embodiment, the adjustment knob 2 has three positions based on its rotation angle, namely the 0-degree position (see...). Figure 12 First gear (see) Figure 13 ) and second gear (see Figure 14 The adjustment and switching methods between each gear are the same as in Example 1, and will not be repeated in this example.
