Description

Technical Field

[0001] This application relates to the field of small household appliance technology, and more specifically, to a cup assembly of a blender and a blender. Background Technology

[0002] The blender uses a blade assembly to mix and chop food, and then uses a filter assembly to filter it, achieving rapid pulverization and separation of residue and liquid. Currently, existing blenders suffer from poor pulverization, resulting in low juice yield. Summary of the Invention

[0003] This application provides a cup assembly and a blender for a blender, which has a good crushing effect and a high juice yield.

[0004] A cup assembly of a blender, comprising:

[0005] The cup body forms a cup cavity;

[0006] A filter section is rotatably disposed within the cup cavity. The filter section includes a filter cylinder forming a filter cavity and a blocking section connected to the top of the filter cylinder. The blocking section can at least cover the edge area above the filter cavity.

[0007] The pulverizing section is rotatably disposed within the filter chamber.

[0008] The cup assembly and blender provided in this application allow the food to adhere to the inner wall of the filter cylinder due to centrifugal force when the filter section rotates. The food then rises upwards along the inner wall of the filter cylinder. Since the blocking part is located at the edge of the filter chamber, the food that rises to the top of the filter cylinder can be blocked by the blocking part and flow back into the filter chamber. An internal circulation turbulence layer is formed inside the filter chamber, allowing the food to flow back to the grinding area and be ground again by the grinding part. This results in multiple cutting and grinding processes, leading to better grinding effect and higher juice yield.

[0009] Optionally, the blocking part is configured as a hollow annular structure, which covers the upper part of the filter chamber and is located at the outermost annular area. This design takes into account that the food rises along the inner wall of the filter cylinder, so placing the blocking part directly opposite the annular area at the edge is more effective, better at blocking the food, and also saves materials.

[0010] Optionally, the blocking part is detachably connected to the filter cartridge. This allows the blocking part to be cleaned separately, resulting in a more thorough cleaning.

[0011] Optionally, the pulverizing section includes a first blade located at the bottom of the filtering chamber. The tip of the first blade is bent upwards, and the minimum distance between the tip of the first blade and the filtering cylinder is 2-5 mm in a direction perpendicular to the axis of rotation of the filtering cylinder. Positioning the tip of the first blade close to the filtering cylinder facilitates the removal of food from the cylinder wall and prevents excessive food from adhering to the cylinder wall.

[0012] Optionally, the pulverizing section includes a first blade located at the bottom of the filter chamber, with the blade tip bent upwards. The filter cylinder also includes a turbulence-inducing section protruding from the inner wall. In a direction perpendicular to the rotation axis of the filter cylinder, the minimum distance between the blade tip and the turbulence-inducing section is 2–15 mm. This distance prevents large food particles from adhering to the bottom of the filter cylinder under the influence of gravity and centrifugal force.

[0013] Optionally, the direction of rotation of the filtering section is opposite to that of the grinding section. This increases the relative rotational speed between the filtering section and the grinding section, thereby increasing the grinding force and further improving the grinding effect.

[0014] Optionally, the filter section further includes a positioning section connected to the blocking section, and the cup assembly further includes a cup lid covering the cup body. The cup lid includes a mating section, and the positioning section and the mating section are positioned and mated with the axis of rotation of the filter section as the positioning center. This configuration allows the cup lid to restrict the filter section, preventing it from moving upwards during rotation and ensuring the coaxiality of the upper and lower ends of the filter section during rotation, thus preventing violent shaking.

[0015] Optionally, the cup assembly further includes a controllable rotatable grinding shaft and a filtering shaft. The grinding shaft is connected to the grinding section, and the filtering shaft is connected to the filtering section. The filtering shaft is sleeved on the outside of the grinding shaft, coaxially arranged, and rotatable relative to it. This arrangement, with the grinding shaft passing through the filtering shaft, reduces the space occupied by the grinding shaft while ensuring efficient power transmission, resulting in a simpler structure.

[0016] Optionally, the cup assembly further includes a gearbox, through which the grinding section shaft is connected to the filtering section shaft. The gearbox can output at least two different speeds to accommodate the speed requirements of the grinding and filtering processes.

[0017] A blending press, comprising:

[0018] The main unit includes an output terminal capable of outputting torque;

[0019] The cup assembly as described in any of the above embodiments is assembled into the main unit, and one of the grinding section and the filtering section is connected to the output end. This blender has good grinding effect and high juice yield. Attached Figure Description

[0027] The technical solutions in the embodiments (or "implementations") of this application will be clearly and completely described herein with reference to the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0028] If the embodiments of this application contain terms relating to directional indications or positional relationships (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationships and movements between components in a specific posture (as shown in the attached figures); if the specific posture changes, the directional indications or positional relationships will also change accordingly. Furthermore, the terms "first" and "second" used in the embodiments of this application are only for descriptive convenience and should not be construed as indicating or implying relative importance.

[0029] Please refer to Figure 1 , Figure 1 This is a schematic diagram of a blender 100 shown as an exemplary embodiment of this application.

[0030] This application provides a blending press 100, which includes a main unit 10 and a cup assembly 20. The cup assembly 20 is assembled to the main unit 10, and the assembly method includes, but is not limited to, a detachable method. Figure 1 In the illustrated embodiment, the cup assembly 20 is located above the main unit 10, which is a base-type main unit, but is not limited to this.

[0031] Please refer to Figure 2 and Figure 3 , Figure 2 yes Figure 1 An exploded view of the cup component 20 shown in the figure. Figure 3 This is a cross-sectional view of cup component 20.

[0032] The cup assembly 20 includes a cup body 21, a cup holder 22 disposed at the bottom of the cup body 21, a cup lid 23 covering the top of the cup body 21, a crushing section 24, and a filtering section 25. The cup body 21 is hollow, forming a cup cavity 210. The cup holder 22 is connected to the bottom of the cup body 21, and the connection method includes, but is not limited to, a detachable connection.

[0033] In this embodiment, the cup holder 22 is housed within the space at the bottom of the cup body 21, and a sealing ring is provided between the cup holder 22 and the cup body 21 to seal the cup cavity 210. The cup lid 23 is configured to be detachable from the cup body 21, that is, it can be inserted or removed, but is not limited thereto. A handle is also provided on the side of the cup body 21.

[0034] A filter section 25 is rotatably disposed within the cup cavity 210 for filtering food ingredients. The filter section 25 includes a filter cylinder 251 forming a filter cavity 250 and a blocking portion 252 connected to the top of the filter cylinder 251, the blocking portion 252 at least covering the edge region above the filter cavity 250. The filter cylinder 251 may include a filter screen with perforations. A grinding section 24 is rotatably disposed within the filter cavity 250 for grinding the food ingredients within the filter cavity 250. Figure 2 In the embodiment shown, the crushing part 24 is provided on the cup holder 22.

[0035] As described above, when the filter section 25 rotates, the food is subjected to centrifugal force and adheres to the inner wall of the filter cylinder 251, rising upwards along the inner wall. Since the blocking part 252 blocks the edge area above the filter chamber 250, the food that rises to the top of the filter cylinder 251 can be blocked by the blocking part 252 and flow back into the filter chamber 250, forming an internal circulation turbulence layer inside the filter chamber 250. This allows the food to flow back to the crushing area and be crushed again by the crushing part 24, resulting in multiple cutting and crushing processes, better crushing effect, and higher juice yield. Figure 3 The arrows in the diagram illustrate a schematic of the inner circulation turbulence layer.

[0036] This application does not specifically limit the structure of the blocking part 252. For example, the blocking part 252 can be a fully enclosed blocking part 252 that covers the top of the filter chamber 250. In this embodiment, the blocking part 252 is set as a hollow annular structure, and the blocking part 252 covers the top of the filter chamber 250 and is located at the outermost annular area. This solution mainly considers that the food rises upward along the inner wall of the filter cylinder 251, so setting the blocking part 252 directly opposite the annular area at the edge is more effective, more conducive to the blocking effect, and can also save materials.

[0037] In an alternative embodiment, the blocking part 252 and the filter cartridge 251 are detachably connected, so that the blocking part 252 can be cleaned separately, and the cleaning is more thorough.

[0038] In one embodiment, such as Figure 3 As shown, the filter cylinder 251 also includes a turbulence-inducing section 251a protruding from the inner wall. The turbulence-inducing section 251a can enhance the agitation of the food ingredients, allowing them to be more thoroughly pulverized. Figure 3 In the embodiment shown, the turbulence portion 251a is configured as a strip-shaped turbulence rib extending along the height direction of the filter cylinder 251. Multiple strip-shaped turbulence ribs are provided and are distributed at intervals in the circumferential direction on the inner wall of the filter cylinder 251.

[0039] In one embodiment, the pulverizing section 24 includes a first blade 241 disposed at the bottom of the filter chamber 250, with the tip of the first blade 241 bent upwards. This allows the first blade 241 to tumble the food upwards from the bottom of the filter chamber 250, preventing food from accumulating at the bottom and increasing the likelihood of the food at the bottom being cut and pulverized.

[0040] In one embodiment, in a direction perpendicular to the rotation axis of the filter cylinder 251, the minimum distance δ1 between the tip of the first blade 241 and the filter cylinder 251 is 2–5 mm. For example, δ1 can be 2 mm, 2.5 mm, 2.9 mm, 3 mm, 4 mm, or 5 mm, but is not limited to these. In this embodiment, setting the tip of the first blade 241 closer to the filter cylinder 251 facilitates the removal of food from the cylinder wall and avoids excessive food adhering to the cylinder wall.

[0041] exist Figure 3In the illustrated embodiment, two first blades 241 are provided, spaced 180° apart, but this is not a limitation. More first blades 241 can be provided. Additionally, the pulverizing section 24 includes a second blade 242, positioned above the first blades 241. The tip of the second blade 242 can also be bent upwards, but this is not a limitation. The diameter of the circumference of the tip of the second blade 242 is smaller than the diameter of the circumference of the tip of the first blade 241, thus forming multiple turbulence layers. The number of second blades 242 is not limited; one or more can be provided.

[0042] In one embodiment, please combine Figure 2 and Figure 3 The filter section 25 further includes a positioning section 253 connected to the blocking section 252, and the cup lid 23 includes a mating section 231. The positioning section 253 and the mating section 231 are positioned and mated with the axis of rotation of the filter section 25 as the positioning center. This configuration allows the cup lid 23 to restrict the filter section 25, preventing it from shifting upwards when rotating and ensuring the coaxiality of the upper and lower ends of the filter section 25 during rotation, thus preventing violent shaking.

[0043] In one embodiment, one of the positioning part 253 and the mating part 231 includes a shaft hole, and the other includes a shaft body, the shaft body being inserted into the shaft hole. In this embodiment, the positioning part 253 includes a shaft body, the mating part 231 includes a shaft hole, and the shaft body is coaxial with the rotating shaft of the filter part 25.

[0044] In one embodiment, such as Figure 2 As shown, the positioning part 253 is connected to the blocking part 252 through the connecting rib 254. The connecting rib 254 is small in size and occupies little space. It can also form a space above the filter cylinder 251 that communicates with the filter cavity 250, making it convenient to add food into the filter cavity 250.

[0045] exist Figure 2 In the example shown, in order to increase the connection strength, multiple connecting ribs 254 can be provided. The multiple connecting ribs 254 are respectively connected to the positioning part 253 and the blocking part 252. The connecting ribs 254 are inclined upward and inward from the blocking part 252 and connected to the positioning part 253. A gap is left between two adjacent connecting ribs 254.

[0046] In one alternative embodiment, such as Figure 3 As shown, the filter cartridge 251 includes a bottom 2510 made of plastic material, a body 2511 made of plastic material, and a filter screen 2512 made of metal material. The filter screen 2512 is connected to the body 2511, and the two are injection molded into an integral structure. The positioning part 253 and the connecting rib 254 can also be injection molded simultaneously with the above two.

[0047] In one embodiment, the bottom 2510 is detachable and integrated into the cup holder 22. The pulverizing part 24 is also integrated into the cup holder 22. Thus, when the cup holder 22 is removed, the pulverizing part 24 is exposed for easy cleaning. The connection between the bottom 2510 and the body 2511 can be, but is not limited to, snap-fit. A sealing ring can also be provided between the bottom 2510 and the body 2511 to seal the filter chamber 250.

[0048] In one embodiment, the direction of rotation of the filter section 25 is opposite to that of the grinding section 24. This increases the relative rotational speed between the filter section 25 and the grinding section 24, thereby increasing the grinding force and further improving the grinding effect.

[0049] Please continue to refer to this. Figure 3 In one embodiment, the cup assembly 20 further includes a controllably rotatable grinding shaft 26 and a filtering shaft 27. The grinding shaft 26 is connected to the grinding section 24 and synchronously drives the grinding section 24 to rotate. The filtering shaft 27 is connected to the filtering section 25 and synchronously drives the filtering section 25 to rotate. The filtering shaft 27 is sleeved on the outside of the grinding shaft 26, coaxially arranged, and rotatable relative to it. This arrangement, with the grinding shaft 26 passing through the filtering shaft 27, reduces the space occupied by the grinding shaft 26 while ensuring effective power transmission, resulting in a simpler structure.

[0050] In one embodiment, the cup assembly 20 further includes a transmission 28, through which the pulverizing section shaft 26 is connected to the filtering section shaft 27. The transmission 28 can be configured as a reducer or a speed increaser to output at least two different speeds to accommodate the speed requirements of the pulverizing and filtering processes. The transmission 28 can be a planetary gear train, but is not limited to it.

[0051] Please refer to Figure 4 , Figure 4 This is another sectional view of the cup assembly 20.

[0052] In one embodiment, in a direction perpendicular to the rotation axis of the filter cylinder 251, the minimum distance δ2 between the tip of the first blade 241 and the turbulence-disrupting portion 251a is 2–15 mm. For example, δ2 can be 2 mm, 5 mm, 10 mm, 12 mm, or 15 mm, but is not limited to these values. This distance prevents large food particles from adhering to the bottom of the filter cylinder 251 under the influence of gravity and centrifugal force. For example, the upward-bent portion of the first blade 241 can be set parallel to the cylinder wall, thus forming a rotational cutting path approximately parallel to the cylinder wall, which more effectively tumbles large food particles from the bottom of the cylinder.

[0053] Please refer to Figure 5 and Figure 6 , Figure 5 This is a bottom view of cup body 21. Figure 6 This is a schematic diagram of cup holder 22.

[0054] In one embodiment, the cup body 21 and the cup holder 22 are detachably connected. Specifically, the cup body 21 and the cup holder 22 are detachably connected by screwing. In this embodiment, the outer surface of the cup holder 22 is provided with a snap fastener 221, and the inner surface of the cup body 21 is provided with a snap fastener groove 211 that mates with the snap fastener 221. During installation, the cup holder 22 is rotated in a preset direction to screw the snap fastener 221 into the snap fastener groove 211, thus completing the installation. The rotation direction of the cup holder 22 when installed on the cup body 21 can be set to be the same as the rotation direction of the crushing part 24 to prevent the cup holder 22 from rotating back and detaching from the cup body 21. Of course, the rotation of the cup holder 22 can also be limited by a limiting structure. The number of snap fasteners 221 and snap fastener grooves 211 is not limited; multiple snap fasteners 221 and snap fastener grooves 211 can be provided and screwed in one-to-one to ensure the reliability of the connection and the balance of force.

[0055] Please combine Figure 3 and Figure 7 , Figure 7 This is a cross-sectional view of host 10.

[0056] In one embodiment, the main unit 10 includes a motor 11, the motor shaft of which serves as an output end 12 capable of outputting torque. One of the pulverizing section 24 and the filtering section 25 is connected to the output end 12, thereby transmitting power to the pulverizing section 24 and the filtering section 25. In this embodiment, the output end 12 is connected to the pulverizing section shaft 26, or more precisely, the output end 12 is connected to the pulverizing section shaft 26 via a lower clutch 14. The pulverizing section shaft 26 also has an upper clutch 29 that engages with the lower clutch 14. Thus, the main unit 10 has only one output end 12, making its structure simpler and its size appropriately reduced. After receiving power, the pulverizing section shaft 26 can transmit the power to the filtering section shaft 27 via a gearbox 28, and then to the filtering section 25.

[0057] 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.
