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 for a blender and a blender, which can improve the pulverizing effect and increase the juice yield.

[0004] A cup assembly for 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 part connected to the top of the filter cylinder. The blocking part is configured as a hollow annular member. The blocking part covers the filter cavity and is located at the outermost annular area. The filter cylinder and the cup body are separated by a gap of 1 to 10 mm in a direction perpendicular to the rotation axis of the filter section. This gap forms an external circulation channel.

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

[0008] The cup assembly and the blender provided in this application allow the centrifugal force generated when the filter section rotates to allow the juice to flow from the filter chamber into the cup chamber. Since the gap δ1 between the cup body and the filter cylinder is small, only 1 to 10 mm, the liquid level of the juice in this gap can rise rapidly in the external circulation channel. The juice can also flow back into the filter chamber through the hollow part of the blocking part. The blocking part is also used to prevent the juice from flowing backward. During this process, the juice can be temporarily separated from the food residue, reducing the water content of the food in the filter chamber. Therefore, it is more conducive to crushing the food residue, resulting in a higher juice yield. It can also make the juice accumulated in the external circulation channel circulate.

[0009] Optionally, the filter cylinder includes a filter screen portion with perforations, which is arranged around the grinding section. That is, in the height direction of the cup body, the height of the filter screen portion is approximately the same as the height of the grinding section. Under the rotation of the grinding section, the kinetic energy of the food at this part is relatively large, which is more conducive to the drainage of juice.

[0010] Optionally, the pulverizing section includes a first blade with an upwardly curved tip. The distance between the tip and the filter screen is equidistant at all points in the rotation direction perpendicular to the axis of rotation of the filtering section; or, the tip is inclined relative to the wall of the filter cylinder at an angle not exceeding 30°, with the tip closer to the filter screen. If the distance between the tip and the filter screen is equidistant, they are approximately parallel, forming a vertical cutting surface that promotes the rise of the liquid level in the external circulation channel, facilitating the external circulation turbulence of the juice. If the tip is inclined, the turbulence effect on the food is increased, ensuring both external circulation turbulence and efficient pulverization of the food.

[0011] Optionally, in the direction perpendicular to the rotation axis of the filter section, the distance between the end of the blade tip and the filter screen is 2-5 mm. Because the δ2 ​​dimension is small, the first blade can agitate the food within a larger range of the filter chamber, and can also prevent large pieces of food from adhering to the filter cylinder wall, allowing the food to be thoroughly pulverized.

[0012] Optionally, the upper surface of the blocking part gradually slopes downward from the outer ring to the inner ring. In this way, the upper surface of the blocking part can also play a guiding role, allowing the juice to flow more smoothly into the filter chamber and preventing it from accumulating at the blocking part.

[0013] 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 shifting upwards during rotation and ensuring the coaxiality of the upper and lower ends of the filter section during rotation, thus preventing violent shaking.

[0014] Optionally, the filter section further includes a connecting rib that connects the blocking section and the positioning section, and at least one surface of the connecting rib is configured as a spiral surface. The spiral surface can guide the flow, quickly guiding the liquid accumulated at the blocking section into the filter cylinder, accelerating the flow of food and improving the pulverizing effect.

[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 transmission unit, through which the pulverizing section shaft is connected to the filtering section shaft. The transmission unit can be configured to increase or decrease the rotational speed, so that at least two different rotational speeds can be output to adapt to the speed requirements during pulverization and filtration.

[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 crushing section and the filtering section is drively connected to the output end. In this way, the main unit has only one output end, making its structure simpler and its size appropriately reduced. 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 , Figure 2 for Figure 1 The image shows a cross-sectional view of the agitator 100.

[0032] The main unit 10 includes an output terminal 101 capable of outputting torque, and the output terminal 101 is connected to a lower clutch 102. Specifically, the main unit 10 also includes a motor 11, and the motor shaft of the motor 11 serves as the output terminal 101.

[0033] The cup assembly 20 includes a cup body 21, a grinding section 22, and a filtering section 23. The cup body 21 forms a cup cavity 210, and the filtering section 23 is rotatably disposed within the cup cavity 210. The filtering section 23 includes a filter cylinder 231 forming a filter cavity 230 and a blocking section 232 connected to the top of the filter cylinder 231. The filter cylinder 231 has holes for juice discharge, and the grinding section 22 is rotatably disposed within the filter cavity 230.

[0034] The blocking part 232 is configured as a hollow annular member. The blocking part 232 covers the filter cavity 230 and is located in the outermost annular area. The filter cylinder 231 and the cup body 21 have a gap in the direction perpendicular to the rotation axis of the filter part 23. This gap forms an external circulation channel 2100. This gap is δ1, and δ1 is 1 to 10 mm. For example, δ1 can be 1 mm, 2 mm, 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, or 10 mm, but is not limited to these.

[0035] As described above, the centrifugal force generated when the filter section 23 rotates can cause the juice to flow from the filter chamber 230 into the cup chamber 210. Since the gap between the cup body 21 and the filter cylinder 231 is small, δ1 is only 1 to 10 mm, the liquid level of the juice in this gap can rise rapidly in the external circulation channel 2100. The juice can also flow back into the filter chamber 230 through the hollow part of the blocking part 232. The blocking part 232 is also used to prevent the juice from flowing backward. During this process, the juice can be temporarily separated from the food residue, reducing the water content of the food in the filter chamber 230. Therefore, it is more conducive to crushing the food residue, resulting in a higher juice yield. It can also make the juice accumulated in the external circulation channel 2100 circulate. Figure 2 The arrow in the image points to the direction of the external circulation turbulence.

[0036] In one embodiment, the filter cylinder 231 includes a filter screen portion 2310 with perforations, which is arranged around the grinding section 22. That is, in the height direction of the cup body 21, the height of the filter screen portion 2310 is approximately the same as the height of the grinding section 22. Under the rotational action of the grinding section 22, the kinetic energy of the food at this location is relatively large, which is more conducive to the drainage of juice. It should be noted that the height direction of the cup body 21 is consistent with the axial direction of the grinding section 22.

[0037] Please refer to Figure 3 , Figure 3 This is a cross-sectional view of the 20-part structure of the cup assembly.

[0038] In one embodiment, the pulverizing section 22 includes a first blade 221, which has an upwardly bent tip 2210. In a direction perpendicular to the rotation axis of the pulverizing section 22, the distance δ2 between the end of the tip 2210 and the filter section 2310 is 2–5 mm. For example, δ2 can be 2 mm, 2.5 mm, 2.9 mm, 3 mm, 3.5 mm, 4 mm, or 5 mm, but is not limited to these. Because δ2 is small, the first blade 221 can agitate the food within a larger range of the filter chamber 230, and can also prevent large pieces of food from adhering to the wall of the filter cylinder 231, allowing the food to be thoroughly pulverized. Figure 3In the illustrated embodiment, two first blades 221 are provided, and the two first blades 221 are arranged 180° apart, but this is not limited to this. For example, the first blades 221 can be bent at two bending points, such as bending downward at the first bending point and bending upward at the second bending point, wherein the first bending point is closer to the axis of the crushing section 22 than the second bending point.

[0039] In one embodiment, the distance between the blade tip portion 2210 and the filter screen portion 2310 is equidistant in the direction perpendicular to the rotation axis of the filter section 23. That is, the blade tip portion 2210 and the filter screen portion 2310 are approximately parallel, which makes the blade tip portion 2210 form a vertical cutting surface, which is beneficial to promoting the rise of the liquid level in the external circulation channel 2100 and to achieving external circulation turbulence of the juice.

[0040] In another embodiment, the blade tip 2210 is inclined relative to the filter cylinder 2310, with an inclination angle β not exceeding 30°, and the end of the blade tip 2210 is closer to the filter screen 2310. β can be 5°, 10°, 15°, 20°, 25°, or 30°, but is not limited to these. This arrangement increases the turbulence effect on the food, ensuring both external circulation and turbulence of the juice while also facilitating food pulverization.

[0041] exist Figure 3 In the illustrated embodiment, the pulverizing section 22 further includes a plurality of second blades 222, which are disposed above the first blade 221 and are circumferentially spaced along the axis of rotation of the pulverizing section 22. The diameter of the circumference of the tip of the second blade 222 is smaller than the diameter of the circumference of the tip of the first blade 221. The second blades 222 may also be bent upwards, but are not limited thereto.

[0042] In one embodiment, the upper surface of the blocking portion 232 gradually slopes downward from the outer ring to the inner ring. In this way, the upper surface of the blocking portion 232 can also play a guiding role, allowing the juice to flow more smoothly into the filter chamber 230 and preventing it from accumulating at the blocking portion 232.

[0043] Please combine Figure 2 and Figure 3 The cup assembly 20 also includes a cup lid 24, which covers the top of the cup body 21 and may have a pressure relief hole.

[0044] In one embodiment, the filter section 23 further includes a positioning section 233 connected to the blocking section 232, and the cup lid 24 includes a mating section 241. The positioning section 233 and the mating section 241 are positioned and mated with the axis of rotation of the filter section 23 as the positioning center. This configuration allows the cup lid 24 to restrict the filter section 23, preventing it from shifting upwards during rotation and ensuring the coaxiality of the upper and lower ends of the filter section 23 during rotation, thus preventing violent shaking.

[0045] In one embodiment, one of the positioning part 233 and the mating part 241 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 233 includes a shaft body, the mating part 241 includes a shaft hole, and the shaft body is coaxial with the rotating shaft of the filter part 23.

[0046] Please combine Figures 3 to 5 , Figure 4 This is a top view of the filter section 23. Figure 5 This is a schematic diagram of cup assembly 20 with cup body 21 and cup lid 24 removed.

[0047] In one embodiment, the filter section 23 further includes a connecting rib 234. The positioning section 233 is connected to the blocking section 232 through the connecting rib 234. The connecting rib 234 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 230, making it convenient to add food into the filter cavity 230.

[0048] In this embodiment, in order to increase the connection strength, multiple connecting ribs 234 are provided. All multiple connecting ribs 234 are connected to the positioning part 233 and the blocking part 232. The connecting ribs 234 are inclined upward and inward from the blocking part 232 and connected to the positioning part 233. A gap is left between two adjacent connecting ribs 234.

[0049] In one embodiment, at least one surface of the connecting rib 234 is configured as a spiral surface. The spiral surface can act as a guide, quickly guiding the liquid accumulated at the blocking part 232 into the filter chamber 230 to accelerate the flow of food and improve the pulverizing effect.

[0050] In one alternative embodiment, such as Figure 3 As shown, the filter cartridge 231 also includes a bottom 2311 and a body 2312 made of plastic material. The filter screen 2310 is connected to the body 2312, and the two can be injection molded into an integral structure. The positioning part 233 and the connecting rib 234 can also be injection molded simultaneously with the above two.

[0051] In this embodiment, the bottom of the cylinder 2311 is a detachable bottom, and the connection between the bottom of the cylinder 2311 and the cylinder body 2312 includes, but is not limited to, snap-fit. A sealing ring may also be provided between the bottom of the cylinder 2311 and the cylinder body 2312 to prevent leakage of the filter chamber 250.

[0052] 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 22 and synchronously drives the grinding section 22 to rotate. The filtering shaft 27 is connected to the filtering section 23 and synchronously drives the filtering section 23 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.

[0053] In one embodiment, the cup assembly 20 further includes a transmission unit 28, through which the pulverizing shaft 26 is connected to the filtering shaft 27. The transmission unit 28 can be configured to increase or decrease the rotational speed, so that at least two different rotational speeds can be output to meet the speed requirements during pulverization and filtering. The transmission unit 28 can be a planetary gear train, but is not limited to it.

[0054] In one embodiment, the rotation directions of the pulverizing section shaft 26 and the filtering section shaft 27 are opposite, which allows the filtering section 23 to rotate in the opposite direction to the pulverizing section, thereby increasing the relative rotation speed between the two and improving the pulverizing and filtering effects.

[0055] Please refer to this again. Figure 2 One of the pulverizing section 22 and the filtering section 23 can be connected to the output end 101 for transmission. In this embodiment, the output end 101 is connected to the pulverizing section shaft 26, or more precisely, the output end 101 is connected to the pulverizing section shaft 26 via a lower clutch 102. The pulverizing section shaft 26 is also provided with an upper clutch 29 that engages with the lower clutch 102. In this way, the main unit 10 has only one output end 101, making the structure of the main unit 10 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 the transmission section 28, and then to the filtering section 23.

[0056] exist Figure 2In the illustrated embodiment, the cup body 21 includes a detachably connected cup seat 212, which is detachably connected by screwing. The transmission part 28 is housed within the cup seat 212. The grinding part shaft 26 is rotatably connected to the cup seat 212. The bottom 2311 of the filter cylinder 231 is integrated into the cup seat 212. The filter cylinder shaft 27 is sleeved on the outside of the grinding part shaft 26 and fixedly connected to the bottom 2311. After the cup seat 212 is detached from the cup body 21, the grinding part 22 is exposed, making it easier to tilt the grinding part 22 and the bottom 2311.

[0057] The cup body 21 is also provided with a juice spout 213 that communicates with the cup cavity 210, and the juice spout 213 has a juice outlet. In addition, a juice valve can be provided inside the juice spout to open or close the juice outlet, and the structure of the juice valve is not limited.

[0058] Please refer to Figure 6 and Figure 7 , Figure 6 This is a cross-sectional view of the filter cartridge 231. Figure 7 This is a cross-sectional view of the crusher 100.

[0059] In one embodiment, the inner surface of the filter cylinder 231 is provided with a first rib 2313, which protrudes toward the crushing part 22. The first rib 2313 can play a turbulence role in the filtration and crushing process. Multiple first ribs 2313 can be provided and distributed at intervals along the circumference of the filter cylinder 231.

[0060] In one embodiment, the inner surface of the cup body 21 is also provided with a second rib 211, which protrudes toward the filter cylinder 231. The second rib 211 can strengthen the cup body 21 on the one hand, and increase the resistance of the juice flowing circumferentially in the gap between the cup body 21 and the filter cylinder 231 on the other hand, which is more conducive to realizing external circulation turbulence.

[0061] 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.
