Description

Technical Field

[0001] The utility model relates to the technical field of household electrical appliances, in particular to a food processing machine capable of reciprocating motion. Background Art

[0002] With the development of society and the improvement of living standards, people's pursuit of dietary diversity and healthy diet is constantly increasing. Therefore, various industrial food processing machines are gradually miniaturized and enter thousands of households. For example, meat grinders not only meet people's needs for healthy diet and nutrition, but also greatly improve people's quality of life, and are therefore loved by people.

[0003] Existing food processing machines, such as meat grinders, include a cup body with a grinding chamber, a grinding device disposed in the grinding chamber, and a motor located below the cup body and driving the grinding device to rotate. When using the food processing machine, the user places the food into the grinding chamber, and the grinding device rotates at high speed driven by the motor to process the food. However, existing food processing machines, especially meat grinders, generally have uneven grinding when cutting food, especially when grinding vegetable leaves. Since the vegetable leaves are light, some of the vegetable leaves will adhere to the side or bottom of the cup body during the grinding process, and the grinding device is fixed in a horizontal position for rotation and cutting, and the vegetable leaves attached to the wall cannot be crushed, resulting in insufficient processing of the food. In order to solve the above problems, some manufacturers will set up a reciprocating motion mechanism in the main unit. Through the motion conversion of the reciprocating motion mechanism, the crushing device can reciprocate up and down in a cyclic motion. Although this solution enables the crushing device to move up and down to achieve a larger range of cutting in the axial direction, when the user misoperates, in order to process more ingredients at one time, they usually put too much into the cup body and exceed the rated capacity scale line. Even in the process of moving upward, the blade cannot effectively cut the ingredients above the blade. In particular, when the user adds more meat ingredients, due to the high viscosity of meat, the ingredients above the blade will move upward with the knife shaft and the blade, which will result in the food above the blade being unable to be effectively cut. The taste of the output ingredients is greatly reduced, seriously affecting the consumer experience. Utility Model Content

[0004] The utility model aims to provide a reciprocating food processor to solve the problem that when the existing food processor processes food, the user adds too much food into the cup body, resulting in the mixing knife still being unable to cut the food above the blade during the reciprocating movement.

[0005] To achieve the above-mentioned purpose, the utility model provides a food processing machine with reciprocating motion, comprising a main machine, a cup body detachably arranged on the main machine, a driving mechanism arranged in the main machine, a reciprocating motion mechanism transmission-connected to the driving mechanism and an output shaft, a stirring knife transmission-connected to the output shaft is arranged in the cup body, the stirring knife comprises a knife shaft and an upper blade and a lower blade axially spaced apart from each other along the knife shaft, a rated capacity scale line is arranged on the side wall of the cup body, the reciprocating motion mechanism is used to drive the knife shaft to drive the upper blade to reciprocate up and down to form a reciprocating cutting space in the axial direction, and the reciprocating cutting space laterally covers the rated capacity scale line.

[0006] The present application sets a driving mechanism and a reciprocating motion mechanism in the main unit, so that when the user uses the food processor to process food, the driving mechanism drives the knife shaft to rotate circumferentially, and the reciprocating motion mechanism drives the knife shaft to reciprocate axially, thereby greatly increasing the axial cutting space of the mixing knife, so that the mixing knife can cut more food, which helps to improve the uniformity and efficiency of cutting, and at the same time can increase the number of food cut in a single time, meeting the user's usage needs.

[0007] The mixing blade includes a blade shaft and an upper blade and a lower blade axially spaced apart along the blade shaft. The side wall of the cup body is provided with a rated capacity scale line. The reciprocating motion mechanism is used to drive the blade shaft to drive the upper blade to reciprocate up and down to form a reciprocating cutting space in the axial direction. The reciprocating cutting space laterally covers the rated capacity scale line, so that when the upper blade reciprocates axially with the blade shaft, when the upper blade moves to the highest position, the upper blade is located above the rated capacity scale line, and when the upper blade moves to the lowest position, the upper blade is located below the rated capacity scale line. Therefore, if the ingredients added by the user are mostly located at the rated capacity scale line or even higher than the rated capacity scale line, the upper blade can still move upward and effectively cut the ingredients above the rated capacity scale line, thereby avoiding the situation where some ingredients are located above the rated capacity scale line during the stirring process, resulting in the inability to effectively cut them, further improving the uniformity of food processing and ensuring the taste of the output food.

[0008] In a preferred implementation of a reciprocating food processor, the distance h1 from the bottom of the reciprocating cutting space to the bottom wall of the cup body and the distance h2 from the rated capacity scale line to the bottom wall of the cup body satisfy: 1 / 9≤(h2-h1) / h2≤1 / 5.

[0009] By making the distance h1 from the bottom end of the reciprocating cutting space to the bottom wall of the cup body and the distance h2 from the rated capacity scale line to the bottom wall of the cup body satisfy: 1 / 9≤(h2-h1) / h2≤1 / 5, it is avoided that the difference between h1 and h2 is small, resulting in a small distance for the upper blade to move downward, which in turn results in a small probability of the upper blade contacting the food when the user fills the food below the rated capacity scale line, resulting in poor crushing effect. At the same time, it can also avoid the output shaft moving upward too long, resulting in the top end of the output shaft being easily deflected when squeezed by the material, resulting in the mixing blade being stuck in the connection with the output shaft, thereby affecting the crushing effect; at the same time, it is avoided that the difference between h1 and h2 is large, resulting in the inability to install other blades under the upper blade, which is effective for the food crushing area, thereby resulting in uneven food crushing and poor effect.

[0010] In a preferred implementation of a reciprocating food processor, the distance h3 from the top of the reciprocating cutting space to the bottom wall of the cup body and the distance h2 from the rated capacity scale line to the bottom wall of the cup body satisfy: -1 / 5≤(h2-h3) / h2≤-1 / 9.

[0011] By setting the distance h3 from the top of the reciprocating cutting space to the bottom wall of the cup body and the distance h2 from the rated capacity scale line to the bottom wall of the cup body to satisfy: -1 / 5≤(h2-h3) / h2≤-1 / 9, it is avoided that the distance from the top of the reciprocating cutting space to the bottom wall of the cup body is smaller than the distance from the rated capacity scale line to the bottom wall of the cup body, resulting in insufficient cutting of food above the upper blade when the upper blade moves to the highest position; at the same time, it is avoided that the distance from the top of the reciprocating cutting space to the bottom wall of the cup body is larger than the distance from the rated capacity scale line to the bottom wall of the cup body, resulting in the upper blade driving the food to move upward too much and easily throw it onto the cup cover when the upper blade moves to the highest position, thereby ensuring the neatness of the cup cover.

[0012] In a preferred implementation of a reciprocating food processor, the lower blade has a first position at the highest point during reciprocating motion, and when the lower blade is at the first position, the distance L1 between the lower blade and the bottom wall of the cup body satisfies: 22 mm ≤ L1 ≤ 25 mm; or,

[0013] The lower blade has a second position at the lowest position during reciprocating motion. When the lower blade is at the second position, a distance L2 between the lower blade and the bottom wall of the cup body satisfies: 2mm≤L2≤5mm.

[0014] When the lower blade is in the first position, the distance L1 between the lower blade and the bottom wall of the cup body is set to satisfy: 22mm≤L1≤25mm, thereby preventing the lower blade from being too close to the bottom wall of the cup body, resulting in the inability to effectively cut the food above the lower blade and causing uneven cutting of the food; at the same time, preventing the lower blade from being too close to the bottom wall of the cup body, resulting in the entire mixing blade needing to reciprocate for a long stroke, resulting in a larger overall structure of the reciprocating motion mechanism, occupying a larger space in the main unit, and causing the entire main unit to be too large.

[0015] When the lower blade is in the second position, the distance L2 between the lower blade and the bottom wall of the cup body is set to satisfy: 1mm≤L2≤5mm, thereby avoiding a situation where the distance between the lower blade and the bottom wall of the cup body is too small, causing the lower blade to get stuck with the food below when rotating, resulting in the mixing blade being unable to rotate; and at the same time, avoiding a situation where the distance between the lower blade and the bottom wall of the cup body is too large, causing the food below the cup body to not be effectively cut, resulting in uneven cutting of the food.

[0016] In a preferred implementation of a reciprocating food processor, the side wall of the cup body is further provided with spoiler ribs, and the topmost end of the reciprocating cutting space is axially lower than the topmost end of the spoiler ribs.

[0017] By arranging spoiler ribs on the side wall of the cup body, the food can be gathered toward the center of the cup body through the spoiler ribs during food processing, thereby ensuring that the food is effectively cut, which helps to further improve the cutting efficiency. At the same time, the top of the reciprocating cutting space is axially lower than the top of the spoiler ribs, ensuring the spoiler effect of the spoiler ribs and avoiding the situation where the top of the reciprocating cutting space is axially higher than the top of the spoiler ribs, resulting in the food not being able to obtain spoiler flow when it moves to the highest point, causing uneven cutting of the food.

[0018] In a preferred implementation of a reciprocating food processor, the distance between the top of the spoiler rib and the top of the reciprocating cutting space is L3, and the distance between the top of the spoiler rib and the bottom wall of the cup body is L4, wherein L3 and L4 satisfy 1 / 4L4≤L3≤1 / 2L4; or,

[0019] The inner wall of the cup body is provided with a groove which is concave in the vertical direction, and a plurality of grooves are provided along the circumference of the inner wall, and spoiler ribs are formed between two adjacent grooves.

[0020] By setting the distance L3 between the top of the spoiler rib and the top of the reciprocating cutting space, and the distance L4 between the top of the spoiler rib and the bottom wall of the cup body to satisfy 1 / 4L4≤L3≤1 / 2L4, it is avoided that the distance between the top of the spoiler rib and the top of the reciprocating cutting space is too small relative to the distance between the top of the spoiler rib and the bottom wall of the cup body, resulting in insufficient cutting of the food above the upper blade when the upper blade moves to the highest position; at the same time, it is avoided that the distance between the top of the spoiler rib and the top of the reciprocating cutting space is too large relative to the distance between the top of the spoiler rib and the bottom wall of the cup body, resulting in the upper blade moving too much upward to easily throw the food onto the cup cover when the upper blade moves to the highest position, thereby ensuring the neatness of the cup cover.

[0021] By forming spoiler ribs between two adjacent grooves, when the food is thrown onto the side wall of the cup body, the food can be prevented from adhering to the side wall of the cup body due to the action of the grooves, and at the same time can be gathered at the center of the cup body with the help of the spoiler ribs, thereby further improving the uniformity of food cutting.

[0022] In a preferred implementation of a reciprocating food processor, the baffle ribs extend toward the bottom wall of the cup body to below the lower blade.

[0023] By setting the spoiler ribs to extend toward the bottom wall of the cup body to below the lower blade, the food cut around the lower blade can be completely within the spoiler range of the spoiler ribs, and the food in the entire cutting area of ​​the mixing knife can be disturbed by the spoiler ribs, which helps to further improve the cutting efficiency.

[0024] In a preferred implementation of a reciprocating food processor, a concave waist portion is provided on the top of the knife shaft for taking, and a vertical height L5 of the waist portion satisfies: 15mm≤L5≤23mm.

[0025] By providing a concave waist portion at the top of the blade shaft for picking up, the user can use the waist portion to pick up the blender blade, which is convenient for the user to hold and improves the efficiency of picking up. At the same time, the vertical height L5 of the waist portion is set to meet the following conditions: 15mm≤L5≤23mm, to avoid the situation where the vertical height of the waist portion is too small, resulting in the user's fingers being unable to reach into the waist portion, causing inconvenience in picking up; at the same time, to avoid the situation where the vertical height of the waist portion is too large, resulting in the entire waist portion occupying too large an area on the blade shaft, resulting in the entire blender blade occupying too much axial space.

[0026] In a preferred implementation of a reciprocating food processor, a concave waist portion is provided on the top of the knife shaft for picking up, and when the knife shaft is at the lowest end, the depth L6 from the top of the waist portion to the cup mouth of the cup body satisfies: 50mm≤L6≤70mm.

[0027] When the blade shaft is at the lowest end, the depth L6 between the top of the waist portion and the cup mouth of the cup body is set to satisfy: 50mm≤L6≤70mm, thereby avoiding the situation where the top of the waist portion is too shallow from the cup mouth of the cup body, resulting in too small a reciprocating motion range of the stirring blade; and at the same time, avoiding the situation where the top of the waist portion is too deep from the cup mouth of the cup body, resulting in the user having to reach a large distance into the cup body, making it inconvenient to take the blade.

[0028] In a preferred implementation of a reciprocating food processor, the mixing blade also includes a middle blade located between the upper blade and the lower blade, and when the middle blade is in the highest position, the vertical height of the middle blade is lower than the vertical height of the rated capacity scale line.

[0029] By configuring the mixing blade to also include a middle blade between the upper blade and the lower blade, the area between the upper blade and the lower blade can be further effectively cut by the middle blade, which can further improve the uniformity and efficiency of food cutting. At the same time, when the middle blade is at the highest position, the vertical height of the middle blade is lower than the vertical height of the rated capacity scale line, so that the middle blade can effectively cut the food below the upper blade, further improving the uniformity of cutting.

[0038] In order to more clearly illustrate the overall concept of the present invention, a detailed description is given below in combination with the accompanying drawings by way of examples.

[0039] It should be noted that many specific details are elaborated in the following description to facilitate a full understanding of the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific implementation methods disclosed below.

[0040] like Figures 1 to 5 As shown, the utility model provides a reciprocating food processing machine, comprising a main machine 1, a cup body 2 detachably arranged on the main machine 1, a driving mechanism 4 arranged in the main machine 1, a reciprocating mechanism 5 and an output shaft 6 connected to the driving mechanism 4, a stirring knife 3 connected to the output shaft 6 is arranged in the cup body 2, the stirring knife 3 comprises a knife shaft 31 and an upper blade 32 and a lower blade 33 arranged axially at intervals along the knife shaft 31, a side wall of the cup body 2 is provided with a rated capacity scale line 23, the reciprocating mechanism 5 is used to drive the knife shaft 31 to drive the upper blade 32 to reciprocate up and down to form a reciprocating cutting space in the axial direction, and the reciprocating cutting space laterally covers the rated capacity scale line 23.

[0041] The present application sets a driving mechanism 4 and a reciprocating mechanism 5 in the main unit 1, so that when the user uses the food processor to process food, the driving mechanism 4 drives the knife shaft 31 to rotate circumferentially, and the reciprocating mechanism 5 drives the knife shaft 31 to reciprocate axially, thereby greatly increasing the axial cutting space of the mixing knife 3, so that the mixing knife 3 can cut more food, which helps to improve the uniformity and efficiency of cutting, and at the same time can increase the number of food cut at a single time to meet the user's usage needs.

[0042] The stirring blade 3 includes a blade shaft 31 and an upper blade 32 and a lower blade 33 arranged axially at intervals along the blade shaft 31. The side wall of the cup body 2 is provided with a rated capacity scale line 23. The reciprocating motion mechanism 5 is used to drive the blade shaft 31 to drive the upper blade 32 to reciprocate up and down to form a reciprocating cutting space in the axial direction. The reciprocating cutting space laterally covers the rated capacity scale line 23, so that when the upper blade 32 reciprocates axially with the blade shaft 31, when the upper blade 32 moves to the highest position, the upper blade 32 is located above the rated capacity scale line 23 (refer to Figure 2), and when the upper blade 32 moves to the lowest position, the upper blade 32 is located below the rated capacity scale line 23 (reference Figure 3 ), so that if the ingredients added by the user are mostly located at the rated capacity scale line 23 or even above the rated capacity scale line 23, the upper blade 32 can still move upward and effectively cut the ingredients above the rated capacity scale line 23, thereby avoiding the situation where part of the ingredients are located above the rated capacity scale line 23 during the stirring process of the ingredients, resulting in the inability to achieve effective cutting, further improving the uniformity of ingredient processing and ensuring the taste of the output ingredients.

[0043] It should be noted that the rated capacity scale line 23 is the maximum capacity of food that the user can add into the cup body. The structure of the rated capacity scale line 23 is not specifically limited in the present application. It can be a scale line printed on the outer wall of the cup body 2, or it can be a scale line convexly set on the outer wall or inner wall of the cup body 2. It will not be repeated here.

[0044] It should be noted that the present application does not specifically limit the relationship between the reciprocating cutting space and the rated capacity scale line 23. As a preferred embodiment of the present application, Figure 3 As shown, the distance h1 from the bottom end of the reciprocating cutting space to the bottom wall of the cup body 2 and the distance h2 from the rated capacity scale line 23 to the bottom wall of the cup body 2 satisfy: 1 / 9≤(h2-h1) / h2≤1 / 5.

[0045] By making the distance h1 from the bottom end of the reciprocating cutting space to the bottom wall of the cup body 2 and the distance h2 from the rated capacity scale line 23 to the bottom wall of the cup body 2 satisfy: 1 / 9≤(h2-h1) / h2≤1 / 5, it is avoided that the difference between h1 and h2 is too small, resulting in a short distance for the upper blade 32 to move downward, and then when the user fills the food to below the rated capacity scale line 23, the probability of the upper blade contacting the food is small, resulting in poor crushing effect. At the same time, it can avoid the output shaft 6 moving upward too long, resulting in the top end of the output shaft 6 being easily deflected when squeezed by the material, resulting in the possibility of the mixing blade 3 being stuck in the connection with the output shaft 6, thereby affecting the crushing effect; at the same time, it is avoided that the difference between h1 and h2 is too large, resulting in the inability to install other blades under the upper blade 32, which is effective for the food crushing area, thereby resulting in uneven food crushing and poor effect.

[0046] As a preferred implementation of the present application, Figure 2 As shown, the distance h3 from the top of the reciprocating cutting space to the bottom wall of the cup body 2 and the distance h2 from the rated capacity scale line 23 to the bottom wall of the cup body 2 satisfy: -1 / 5≤(h2-h3) / h2≤-1 / 9.

[0047] By setting the distance h3 from the top of the reciprocating cutting space to the bottom wall of the cup body 2 and the distance h2 from the rated capacity scale line 23 to the bottom wall of the cup body 2 to satisfy: -1 / 5≤(h2-h3) / h2≤-1 / 9, it is avoided that the distance from the top of the reciprocating cutting space to the bottom wall of the cup body 2 is smaller than the distance from the rated capacity scale line 23 to the bottom wall of the cup body 2, resulting in insufficient cutting of the food above the upper blade 32 when the upper blade 32 moves to the highest position; at the same time, it is avoided that the distance from the top of the reciprocating cutting space to the bottom wall of the cup body 2 is larger than the distance from the rated capacity scale line 23 to the bottom wall of the cup body 2, resulting in the upper blade 32 driving the food to move upward too much and easily throw it onto the cup cover when the upper blade 32 moves to the highest position, thereby ensuring the neatness of the cup cover.

[0048] It should be noted that the present application does not specifically limit the relationship between the lower blade 33 and the bottom wall of the cup body 2. As a preferred embodiment of the present application, Figure 2 As shown, the lower blade 33 has a first position at the highest point during reciprocating motion. When the lower blade 33 is at the first position, a distance L1 between the lower blade 33 and the bottom wall of the cup body 2 satisfies: 22 mm ≤ L1 ≤ 25 mm.

[0049] When the lower blade 33 is in the first position, the distance L1 between the lower blade 33 and the bottom wall of the cup body 2 is set to satisfy: 22mm≤L1≤25mm, thereby preventing the lower blade 33 from being too close to the bottom wall of the cup body 2, resulting in the inability to effectively cut the food above the lower blade 33 and causing uneven cutting of the food; at the same time, preventing the lower blade 33 from being too close to the bottom wall of the cup body 2, resulting in the entire mixing blade 3 needing to reciprocate for a longer stroke, causing the overall structure of the reciprocating motion mechanism 5 to be larger, occupying a larger space in the main unit 1, and causing the entire main unit 1 to be too large.

[0050] As a preferred implementation of the present application, Figure 3 As shown, the lower blade 33 has a second position at the lowest point during reciprocating motion. When the lower blade 33 is at the second position, a distance L2 between the lower blade 33 and the bottom wall of the cup body 2 satisfies: 1mm≤L2≤5mm.

[0051] When the lower blade 33 is in the second position, the distance L2 between the lower blade 33 and the bottom wall of the cup body 2 is set to satisfy: 1mm≤L2≤5mm, thereby avoiding a situation where the distance between the lower blade 33 and the bottom wall of the cup body 2 is too small, resulting in the lower blade 33 getting stuck with the food below during rotation, causing the mixing blade 3 to be unable to rotate; and at the same time, avoiding a situation where the distance between the lower blade 33 and the bottom wall of the cup body 2 is too large, resulting in the food below the cup body 2 not being effectively cut, causing uneven cutting of the food.

[0052] As a preferred implementation of the present application, Figure 3As shown, the side wall of the cup body 2 is further provided with a spoiler rib 21 , and the top end of the reciprocating cutting space is axially lower than the top end of the spoiler rib 21 .

[0053] By arranging spoiler ribs 21 on the side wall of the cup body 2, the spoiler ribs 21 can cause the food to gather toward the center of the cup body 2 during food processing, thereby ensuring that the food is effectively cut, which helps to further improve the cutting efficiency. At the same time, the top of the reciprocating cutting space is axially lower than the top of the spoiler rib 21, ensuring the spoiler effect of the spoiler rib 21 and avoiding the situation where the top of the reciprocating cutting space is axially higher than the top of the spoiler rib 21, resulting in the food not being able to obtain spoiler flow when it moves to the highest point, causing uneven food cutting.

[0054] Furthermore, if Figure 2 As shown, the distance between the top of the spoiler rib 21 and the top of the reciprocating cutting space is L3, and the distance between the top of the spoiler rib 21 and the bottom wall of the cup body 2 is L4, wherein L3 and L4 satisfy 1 / 4L4≤L3≤1 / 2L4.

[0055] By setting the distance L3 between the top of the spoiler rib 21 and the top of the reciprocating cutting space and the distance L4 between the top of the spoiler rib 21 and the bottom wall of the cup body 2 to satisfy 1 / 4L4≤L3≤1 / 2L4, it is avoided that the distance between the top of the spoiler rib 21 and the top of the reciprocating cutting space is too small relative to the distance between the top of the spoiler rib 21 and the bottom wall of the cup body 2, resulting in insufficient cutting of the food above the upper blade 32 when the upper blade 32 moves to the highest position; at the same time, it is avoided that the distance between the top of the spoiler rib 21 and the top of the reciprocating cutting space is too large relative to the distance between the top of the spoiler rib 21 and the bottom wall of the cup body 2, resulting in the upper blade 32 driving the food to move upward too much and easily throw it onto the cup cover when the upper blade 32 moves to the highest position, thereby ensuring the neatness of the cup cover.

[0056] It should be noted that the present application does not specifically limit the structure of the spoiler rib 21. As a preferred embodiment of the present application, Figure 2 As shown, the inner wall of the cup body 2 is provided with a groove 22 which is concave in the vertical direction, and a plurality of grooves 22 are provided along the circumference of the inner wall, and a spoiler rib 21 is formed between two adjacent grooves 22. Preferably, as Figure 5 As shown, the grooves 22 are arranged at intervals around the inner wall in a whole circle, so that the spoiler ribs 21 are arranged around the inner wall in a whole circle.

[0057] By forming a spoiler rib 21 between two adjacent grooves 22, when the food is thrown onto the side wall of the cup body 2, the food can be prevented from adhering to the side wall of the cup body 2 under the action of the groove 22, and at the same time, the food can be gathered at the center of the cup body 2 with the help of the spoiler rib 21, thereby further improving the uniformity of food cutting.

[0058] As a preferred embodiment of this embodiment, Figure 3As shown, the spoiler rib 21 extends toward the bottom wall of the cup body 2 to below the lower blade 33 .

[0059] By setting the spoiler rib 21 to extend toward the bottom wall of the cup body 2 to below the lower blade 33, the food cut around the lower blade 33 can be completely within the spoiler range of the spoiler rib 21, and the food in the entire cutting area of ​​the mixing blade 3 can be disturbed by the spoiler rib 21, which helps to further improve the cutting efficiency.

[0060] Of course, the spoiler ribs 21 are not limited to the above-mentioned configuration, and can also be formed by convex ribs extending inwardly from the inner wall of the cup body 2 , and a plurality of ribs are arranged at circumferential intervals along the inner wall of the cup body 2 , which will not be described in detail here.

[0061] As a preferred implementation of the present application, Figure 3 As shown, the top of the knife shaft 31 is provided with a concave waist portion 311 for taking, and the vertical height L5 of the waist portion 311 satisfies: 15mm≤L5≤23mm.

[0062] By providing a concave waist portion 311 at the top of the blade shaft 31 for picking up, the user can use the waist portion 311 to pick up the mixing blade 3, which is convenient for the user to hold and improves the efficiency of picking up. At the same time, the vertical height L5 of the waist portion 311 is set to meet the following conditions: 15mm≤L5≤23mm, so as to avoid the situation where the vertical height of the waist portion 311 is too small, resulting in the user's fingers being unable to extend into the waist portion 311, causing inconvenience in picking up; at the same time, it is avoided that the vertical height of the waist portion 311 is too large, resulting in the entire waist portion 311 occupying too large an area on the blade shaft 31, resulting in the entire mixing blade 3 occupying too much axial space.

[0063] It should be noted that the present application does not specifically limit the location of the waist portion 311. As a preferred embodiment of the present application, Figure 3 As shown, the top of the knife shaft 31 is provided with a concave waist portion 311 for holding. When the knife shaft 31 is at the lowest end, the depth L6 from the top of the waist portion 311 to the cup mouth of the cup body 2 satisfies: 50mm≤L6≤70mm.

[0064] When the blade shaft 31 is located at the lowest end, the depth L6 of the top of the waist portion 311 from the cup mouth of the cup body 2 is set to satisfy: 50mm≤L6≤70mm, thereby avoiding the situation where the top of the waist portion 311 is too shallow from the cup mouth of the cup body 2, resulting in a small reciprocating motion range of the stirring blade 3; at the same time, avoiding the situation where the top of the waist portion 311 is too deep from the cup mouth of the cup body 2, resulting in the user having to reach a large distance into the cup body 2, causing inconvenience in taking the cup.

[0065] As a preferred embodiment of this application, Figure 2As shown, the stirring blade 3 further includes a middle blade 34 located between the upper blade 32 and the lower blade 33. When the middle blade 34 is at the highest position, the vertical height of the middle blade 34 is lower than the vertical height of the rated capacity scale line 23. Preferably, as Figure 2 As shown, two middle blades 34 are provided, that is, there are four blades in total, and their projections on the horizontal plane are staggered.

[0066] By configuring the mixing blade 3 to further include a middle blade 34 between the upper blade 32 and the lower blade 33, the area between the upper blade 32 and the lower blade 33 can be further effectively cut by the middle blade 34, which can further improve the uniformity and efficiency of food cutting. At the same time, when the middle blade 34 is at the highest position, the vertical height of the middle blade 34 is lower than the vertical height of the rated capacity scale line 23, so that the middle blade 34 can effectively cut the food below the upper blade 32, further improving the uniformity of cutting.

[0067] It should be noted that the present application does not specifically limit the number of middle blades 34. It can be one middle blade 34 set between the upper blade 32 and the lower blade 33, or multiple middle blades 34 set between the two, and the multiple middle blades 34 are evenly spaced.

[0068] The technical solution protected by the present utility model is not limited to the above-mentioned embodiments. It should be pointed out that the combination of the technical solution of any embodiment with the technical solution of one or more other embodiments is within the protection scope of the present utility model.

Therefore, these modifications or improvements made without departing from the spirit of the present utility model are within the scope of protection claimed by the present utility model.
