Description

Technical Field

[0001] This application relates to the field of food processor technology, and more specifically, to a cup lid assembly and a food processor. Background Technology

[0002] Some food processors have their blades mounted on the lid assembly. When the lid assembly is being assembled into the blending cup, due to factors such as installation angle deviation, the blades mounted on the lid may come into contact with the cup wall, causing damage to the blending cup or the blades. Utility Model Content

[0003] This application provides a cup lid assembly and a food processor, which can reduce the risk of the blades hitting the cup wall during the assembly of the cup lid assembly into the blending cup.

[0004] In a first aspect, this application provides a cup lid assembly, comprising: a cup lid; an external rotor motor assembled on the cup lid and having a rotor housing; a blade assembly including a protective structure and a blade, wherein the blade is connected to the rotor housing so that the rotor housing can drive the blade to rotate; the protective structure is disposed on the rotor housing, and the maximum outer diameter of the protective structure is greater than the maximum outer diameter of the blade.

[0005] With this configuration, since the protective structure is located on the rotor housing and its maximum outer diameter is larger than that of the blade, during the assembly of the lid assembly into the mixing cup, even if the lid assembly and the mixing cup are not perfectly aligned, the protective structure will contact the cup wall before the blade, thus acting as a barrier. This minimizes the risk of the blade directly colliding with the cup wall, protecting both the blade and the mixing cup and reducing the risk of damage during daily use.

[0006] Optionally, the tool assembly further includes a connector, one end of which is fixedly connected to the rotor housing, and the other end of which is fixedly connected to the tool. As an intermediate component, the connector makes the connection between the tool and the rotor housing more robust, reducing vibration or misalignment caused by high-speed rotation.

[0007] Optionally, the rotor housing is provided with a positioning part, and the protective structure is clamped between the positioning part and the connecting member. The positioning part of the rotor housing provides a relatively clear installation position for the protective structure, allowing it to be accurately clamped between the positioning part and the connecting member. Furthermore, the protective structure is fixed by clamping, which is a simple fixing method, reduces the use of fasteners, and helps to save costs and simplify the structure.

[0008] Optionally, the positioning part includes a first end face and a second end face, the first end face being perpendicular to the axial direction of the rotor housing, and the second end face being perpendicular to the first end face; wherein, the protective structure is sandwiched between the first end face and the connecting member, and the protective structure also has a limiting cooperation with the second end face.

[0009] With this configuration, the protective structure clamped between the first end face and the connector ensures accurate axial positioning of the protective structure, preventing axial movement or offset. The second end face is perpendicular to the first end face, defining the position of the protective structure in a horizontal direction perpendicular to the axial direction. Therefore, the first and second end faces form a structure similar to a "right-angle groove," limiting the protective structure from multiple directions and increasing its stability after installation.

[0010] Optionally, the cup lid assembly further includes a sealing ring sandwiched between the second end face, the protective structure, and the connector.

[0011] The sealing ring can fill the gap between any two of the protective structure, rotor housing, and connectors, forming a relatively comprehensive seal to prevent food residue, liquids, etc., from seeping through or remaining in the gaps. Furthermore, the sealing ring is elastic, allowing it to fit tightly against all three components, generating an inward fixing force that enhances the bonding strength between the protective structure, connectors, and rotor housing, thereby further improving the stability of the protective structure installation.

[0012] Optionally, the rotor housing includes a connecting portion, the outer periphery of which is provided with threads, and the connecting member is provided with a threaded hole adapted to the threads, and the connecting portion is threadedly connected to the connecting member;

[0013] And / or, the cup lid assembly further includes a nut, the cutter has a through hole in the middle extending along its thickness direction, the connector has a threaded portion away from the rotor housing, the threaded portion passes through the through hole, and the nut is fitted onto the outer periphery of the threaded portion and presses against the bottom of the cutter.

[0014] This simple and convenient assembly method helps improve production efficiency and makes it easier for users to maintain and service the equipment in daily use.

[0015] Optionally, the minimum distance between the protective structure and the cutting tool along the axial direction of the rotor housing is in the range of 5mm to 30mm. This solution sets the minimum distance to be greater than or equal to 5mm and less than or equal to 30mm, which can ensure protection without interfering with the stirring effect of the cutting tool.

[0016] And / or, the difference between the maximum outer diameter of the protective structure and the maximum outer diameter of the cutting tool is in the range of 1 mm to 10 mm. This range allows the protective structure to cover the path where the cutting tool may come into contact with the cup wall as effectively as possible.

[0017] Optionally, the protective structure is sheet-like, and its thickness ranges from 0.5mm to 5mm. This allows for a thinner protective structure, which, while meeting basic protective functions, reduces material usage and thus lowers production costs. Furthermore, a thinner protective structure typically means a lighter weight; when the motor drives the blades to rotate and stir, the lighter weight minimizes the impact on the blade rotation.

[0018] Optionally, the protective structure has a perforated area extending through its thickness. The perforated area helps reduce the overall weight of the protective structure.

[0019] Optionally, the protective structure consists of a first part and a second part, the first part and the second part being axially symmetrical about the rotor housing, and the difference between the weight of the first part and the weight of the second part being less than or equal to 3g.

[0020] When the motor drives the blades to rotate, the connected protective structure also rotates accordingly. Because the first and second parts are symmetrical about the axis and have a small weight difference (less than or equal to 3g), the protective structure can maintain a good dynamic balance when rotating. This reduces the imbalance of centrifugal force caused by uneven weight distribution, and avoids problems such as vibration and noise caused by imbalance. As a result, the food processor operates more smoothly and quietly, improving the user experience.

[0021] Secondly, this application provides a food processor, including: a food processor cup; and a cup lid assembly as described in any of the above claims, the cup lid assembly being assembled into the food processor. Attached Figure Description

[0030] This application provides a cup lid assembly and a food processor. The cup lid assembly and food processor will be described in detail below with reference to the accompanying drawings. Unless otherwise specified, the features in the following embodiments and implementations can be combined with each other.

[0031] Please refer to Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the exploded structure of a food processor according to one embodiment. Figure 2 This is an exploded structural diagram of a cup lid assembly according to one embodiment. This application provides a food processor including a food processor cup and a cup lid assembly, the cup lid assembly being detachably assembled to the food processor.

[0032] The cup lid assembly includes a cup lid 10, an external rotor motor 20, and a blade assembly. The cup lid 10 is used to cover the mouth of the mixing cup 60 to seal the mouth of the mixing cup 60. The external rotor motor 20 is assembled to the cup lid 10 and has a rotor housing 21 for outputting power.

[0033] The tool assembly includes a protective structure 30 and a cutting tool 50. The cutting tool 50 is connected to the rotor housing 21 so that the rotor housing 21 can drive the cutting tool 50 to rotate. This connection can be direct or indirect. The protective structure 30 is disposed on the rotor housing (21) and can rotate with the outer rotor motor 20. Furthermore, the maximum outer diameter of the protective structure (30) is larger than the maximum outer diameter of the cutting tool (50).

[0034] Here, "maximum outer diameter of protective structure 30" refers to the maximum straight-line distance between any two points on the contour of protective structure 30 within its overall contour range. Similarly, "maximum outer diameter of tool 50" refers to the maximum straight-line distance between any two points on the contour of tool 50 within its overall contour range.

[0035] With this configuration, since the protective structure 30 is located on the rotor housing 21 and the maximum outer diameter of the protective structure 30 is greater than the maximum outer diameter of the blade 50, during the assembly of the lid assembly into the mixing cup 60, even if the lid assembly and the mixing cup 60 are not perfectly aligned, the protective structure 30 will contact the cup wall of the mixing cup 60 before the blade 50, thus acting as a barrier and preventing the blade 50 from directly colliding with the cup wall of the mixing cup 60. This protects both the blade 50 and the mixing cup 60, reducing the risk of damage to the blade 50 and the mixing cup 60 during daily use.

[0036] Furthermore, the tool assembly also includes a connector 40, one end of which is fixedly connected to the rotor housing 21, and the other end is fixedly connected to the tool 40. As an intermediate component, the connector 40 can make the connection between the tool 50 and the rotor housing 21 more secure, reducing vibration or offset caused by high-speed rotation.

[0037] Please refer to Figure 3 and combined Figure 2 , Figure 3 This is a partial structural cross-sectional view of a cup lid assembly according to one embodiment. In one embodiment, the rotor housing 21 is further provided with a connecting portion 212, which is located on the side of the positioning portion 211 near the connector 40. The outer periphery of the connecting portion 212 is provided with threads, and the connector 40 is provided with a threaded hole 41 adapted to the threads. The connecting portion 212 is threadedly connected to the connector 40. Thus, the operator only needs to align the threaded hole 41 of the connector 40 with the thread of the connecting portion 212 of the rotor housing 21, and then easily install it onto the rotor housing 21 by rotating the connector 40. Similarly, when it is necessary to disassemble the connector 40 for maintenance, replacement of the tool 50, or other maintenance operations, the connector 40 can be removed by rotating it in the opposite direction. This simple and convenient assembly method is beneficial to improving production efficiency and facilitates maintenance and upkeep by users in daily use.

[0038] Furthermore, the connector 40 is also threadedly connected to the cutter 50. Specifically, the cup lid assembly also includes a nut 80, the cutter 50 has a through hole 51 extending through its thickness in the middle, and the connector 40 has a threaded portion 42 away from the rotor housing 21. The threaded portion 42 passes through the through hole 51, and the nut 80 is screwed into the threaded portion 42, fitting around the outer periphery of the threaded portion 42 and pressing against the bottom of the cutter 50, thereby securing the cutter 50 and the connector 40. Similarly, this simple and convenient assembly method helps improve production efficiency and allows users to easily disassemble the cutter 50 during daily use for cleaning or replacement.

[0039] In one embodiment, along the axial direction of the rotor housing 21 (see reference) Figure 3 The minimum distance between the protective structure 30 and the tool 50 along the Z-direction (as shown) is (please refer to) Figure 3 The distance L shown is within the range of 5mm to 30mm. This spacing range ensures that the protective structure 30 does not excessively affect the stirring effect of the blade 50 on the food. It is easy to understand that different foods require different stirring forces and spaces. For example, stirring softer fruits and stirring harder nuts requires different amounts of space between the blade 50 and the protective structure 30. Furthermore, if the spacing range is too large, it will reduce the protective effect of the protective structure 30. Therefore, this solution sets the minimum spacing to be greater than or equal to 5mm and less than or equal to 30mm, ensuring protection without interfering with the stirring effect of the blade 50.

[0040] For example, the minimum spacing mentioned above can be 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, 11mm, 12mm, 13mm, 14mm, 15mm, 16mm, 17mm, 18mm, 19mm, 20mm, 21mm, 22mm, 23mm, 24mm, 25mm, 26mm, 27mm, 28mm, 29mm, or 30mm, but is not limited to these.

[0041] In one embodiment, the difference between the maximum outer diameter of the protective structure 30 and the maximum outer diameter of the blade 50 is in the range of 1 mm to 10 mm. This range allows the protective structure 30 to cover the path where the blade 50 may come into contact with the cup wall as effectively as possible. If the difference is too small, the protective structure 30 may not be able to completely prevent the blade 50 from contacting the cup wall under various unexpected circumstances (such as vibration of the external rotor motor 20, installation errors, etc.); while if the difference is too large, the protective structure 30 will be too large relative to the blade 50, which may interfere with the normal flow of food during the blending process, or occupy too much internal space, resulting in an uncoordinated overall structure of the food processor.

[0042] For example, the difference can be 1mm, 2mm, 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, or 10mm, but is not limited to these.

[0043] In one embodiment, the protective structure 30 comprises a first part and a second part, which are axially symmetrical about the rotor housing 21, and the weight difference between the first part and the second part is less than or equal to 3g. In other words, the weight difference between the first part and the second part is at most 3g. Exemplarily, the weight difference between the first part and the second part can be 0g, 1g, 2g, or 3g, but is not limited thereto.

[0044] When the external rotor motor 20 drives the blade 50 to rotate, the protective structure 30 connected to it also rotates. Since the first and second parts are symmetrical about the axis and have a small weight difference (less than or equal to 3g), the protective structure 30 can maintain a good dynamic balance when rotating, reducing the centrifugal force imbalance caused by uneven weight, and avoiding vibration and noise problems caused by imbalance. This makes the food processor run more smoothly and quietly, improving the user experience.

[0045] Please refer to Figure 4 and combined Figure 3 , Figure 4 yes Figure 3 The enlarged view of part A is shown below. In one embodiment, the rotor housing 21 is provided with a positioning part 211, and the protective structure 30 is clamped between the positioning part 211 and the connecting member 40. With this arrangement, the positioning part 211 of the rotor housing 21 provides a relatively clear installation position for the protective structure 30, allowing the protective structure 30 to be accurately clamped between the positioning part 211 and the connecting member 40. Furthermore, the protective structure 30 is fixed by clamping, which is a simple fixing method and reduces the use of fasteners, thus saving costs and simplifying the structure.

[0046] Furthermore, the positioning part 211 is stepped, including a first end face 2111 and a second end face 2112. The first end face 2111 is perpendicular to the axial direction of the rotor housing 21, and the second end face 2112 is perpendicular to the first end face 2111. The protective structure 30 is sandwiched between the first end face 2111 and the connecting member 40, and the protective structure 30 also has a limiting fit with the second end face 2112.

[0047] The first end face 2111 and the connector 40 clamp the protective structure 30, ensuring the accurate axial position of the protective structure 30 and preventing axial movement or displacement. The second end face 2112 is perpendicular to the first end face 2111, defining the position of the protective structure 30 in a horizontal direction perpendicular to the axial direction. Therefore, the first end face 2111 and the second end face 2112 form a structure similar to a "right-angle groove," limiting the protective structure 30 from multiple directions and increasing the stability of the protective structure 30 after installation.

[0048] Furthermore, the cup lid assembly also includes a sealing ring 70, which is sandwiched between the second end face 2112, the protective structure 30, and the connector 40. In this way, the sealing ring 70 can fill the gap between any two of the protective structure 30, the rotor housing 21, and the connector 40, forming a relatively comprehensive seal and preventing food residue and liquids from seeping through and remaining in the gaps. Moreover, the sealing ring 70 is elastic and can fit tightly against the three components, generating an inward fixing force, enhancing the bonding force between the protective structure 30, the connector 40, and the rotor housing 21, thereby further improving the stability of the protective structure 30 installation.

[0049] Please refer to Figure 5 , Figure 5 This is a schematic diagram of the protective structure 30 according to one embodiment. In one embodiment, the protective structure 30 is sheet-like, with a through hole 31 in the middle for the rotor housing 21 to pass through. The thickness of the protective structure 30 is in the range of 0.5mm to 5mm. This allows the protective structure 30 to be thinner, and while meeting basic protective functions, the thinner protective structure 30 can reduce the amount of material used, thereby reducing production costs. Furthermore, a thinner protective structure 30 generally means that it is lighter in weight. When the outer rotor motor 20 drives the cutter 50 to rotate and stir, the lighter protective structure 30 has less impact on the rotation of the cutter 50.

[0050] In one specific embodiment, the protective structure 30 is sheet-like and circular, with its center coinciding (or approximately coinciding) with the axis of the rotor housing 21 of the outer rotor motor 20, and is evenly distributed around the rotor housing 21. This shape adapts well to the typical circular wall of the mixing cup 60. During the assembly of the lid assembly into the mixing cup 60, regardless of the angle of installation deviation, the circular protective structure 30 can provide a relatively even blocking effect, preventing the blade 50 from colliding with the cup wall. Moreover, the circular sheet-like structure experiences relatively uniform force during rotation, which helps maintain a stable dynamic balance and further reduces the impact on the rotation of the blade 50.

[0051] Please refer to Figure 6 , Figure 6This is a schematic diagram of the protective structure 30 according to another embodiment. In another embodiment, the protective structure 30 is sheet-like, and has a perforated area 32 extending through its thickness. The perforated area 32 helps to reduce the overall weight of the protective structure 30. When the external rotor motor 20 drives the blade 50 to rotate and stir, the lighter protective structure 30 means less burden on the rotation of the blade 50, allowing the blade 50 to rotate more smoothly and stably, thereby reducing the impact on the stirring effect.

[0052] like Figure 6 In the embodiment described, the protective structure 30 is wing-shaped, including a wing root 33 and multiple protective wings 34. The multiple protective wings 34 are connected to the wing root 33 and arranged circumferentially along the wing root 33. The area between two adjacent protective wings 34 is the hollow area 32.

[0053] Similarly, in this embodiment, the protective structure 30 may also be axially symmetrical with respect to the rotor housing 21.

[0054] Of course, in other embodiments, the protective structure 30 may also be, but is not limited to, a polygonal sheet, such as a quadrilateral, hexagon, or octagon.

[0055] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
