[0032] Example:

[0033] like Figure 1 、 Figure 2 and Figure 3 FIG. 1 shows a food processor, which mainly includes a blending cup. The blending cup includes a cup body 100, a blending assembly 200, and a cup lid assembly 300. The cup body 100 has a cup cavity with a cup mouth. The blending assembly 200 is disposed in the cup cavity and can rotate about its own rotation axis, thereby driving the cutting tool on the blending assembly 200 to chop the food in the cup cavity and perform other processing.

[0034] Usually, the cup mouth faces upwards, and the cup cover assembly 300 is in contact with the cup mouth to prevent crumbs or liquid from splashing out of the cup mouth when handling food, and to prevent foreign matter from falling into the cup cavity. The cup cover assembly can be placed on the cup mouth and opened to a certain angle or removed from the cup mouth.

[0035] The cup body consists of two parts: the cup body and the cup bottom. The cup body is columnar or table-shaped. The cup mouth and the cup bottom are opposite to each other in the vertical direction (or up and down direction) of the cup body, forming a cup cavity between the two. Figure 1 , where the cup body includes a main cup shell 110 and an expansion shell 120. The main bodies of the two are opposite to each other, and the two sides are integrally connected to form an annular structure and define the overall shape of the cup cavity. The rotation axis of the stirring component 200 extends from the bottom of the cup to the cup mouth. In the radial direction of the rotation axis of the stirring component 200 or along the radial direction of the cup mouth, the distance from the expansion shell 120 to the rotation axis of the stirring component 200 is greater than the distance from the main cup shell 110 to the rotation axis. In comparison, the main cup shell 110 is closer to the rotation axis of the stirring component 200.

[0036] When the stirring assembly 200 rotates at high speed, the cutter rotates synchronously, forming a first gap channel between the annular area formed by the rotation of the cutter and the main cup shell 110, and a second gap channel between the expansion shell 120, and the two are connected end to end to form a ring. Since the main cup shell 110 is closer to the rotation axis of the stirring assembly 200, the width (radial length) of the first gap channel is smaller than the width of the second gap channel. When the cutter rotates at high speed, the food is chopped and circulates between the first and second gap channels. During this process, the food fragments constantly collide with each other or with the cup wall, and are eventually bounced back to the rotation axis and further crushed by the cutter. Since the width of the first gap channel is smaller, the probability of food fragments colliding in the first gap channel is greater, and therefore the impact on the main cup shell 110 is higher, requiring the cup body to have higher strength to reduce shaking or instability.

[0037] When the gap channel width is larger than the diameter of the food fragments, they need to collide and rebound into the rotating annular area to be crushed. However, when the gap channel width is smaller, the probability of food fragments contacting the rotating cutter increases. At the same stirring speed and cutter structure, the efficiency of crushing large food chunks is negatively correlated with the gap channel width. That is, the smaller the gap channel, the shorter the time required to crush large food chunks, while the wider the gap channel, the longer the crushing time.

[0038] The cup body of a traditional blending cup is usually designed as a cylinder or regular polygon, and the width of its gap channel is always kept within a narrow range. When processing a large amount of food, it will not only cause a greater impact on the cup body, but also require more water to be added to the cup body, which will cause the liquid level to rise. Especially when the stirring component is rotating at high speed, the ring will climb upward along the cup wall under the action of centrifugation. To prevent the liquid from overflowing in this situation, a certain amount of space needs to be reserved between the total height of the cup body and the maximum liquid level. In order to enhance the strength of the cup body, it is usually achieved by increasing the thickness of the cup wall, but this will also increase the weight of the cup body accordingly, thereby improving the stability of the cup body. If a larger diameter cup body is directly used, although the gap channel can be widened, the upper limit of the crushing capacity will be reduced to a certain extent.

[0039] To address this issue, the food processor in this embodiment sets the main cup shell 110 and the expansion shell 120 so that their distances from the rotating axis of the stirring assembly 200 are different, thereby effectively avoiding the reduction of the upper limit of the crushing capacity (the upper limit of the crushing capacity is controlled by the distance between the main cup shell 110 and the rotating axis). In addition, this design also reduces the requirements for the strength of the cup body. The design of the expansion shell 120 is equivalent to increasing the bottom area of ​​the cup body. Therefore, when the same volume of liquid is injected, the liquid level in the cup will decrease accordingly, thereby improving the stability of the cup body. Then the height of the cup body can be reduced accordingly, thereby further reducing the thickness and height of the cup wall, and then reducing the weight of the cup body. At the same time, this design increases the contact area between the bottom of the cup body and the table, thereby improving stability and providing more operational space for reducing the weight of the cup body by thinning the thickness of the cup wall.

[0040] Specifically, the expansion shell 120 includes an arcuate wall 121 and two smooth walls 122. The arcuate wall 121 is opposite to the main cup shell 110, and the cross section of the arcuate wall is an arc. The two smooth walls 122 are arranged opposite to each other and are respectively connected between the arcuate wall 121 and the main cup shell 110. Figure 1 The figure is a top view of the cup body, the main cup shell 110 and the expansion shell 120 extend in the vertical direction. The main cup shell 110 is a cylindrical wall, and the arc range corresponding to the cylindrical wall is to Figure 1 The cylindrical wall shown in FIG. 1 has an arc angle of π, forming a semicircular arc. Similarly, the curved wall 121 of the expansion housing 120 also adopts a semicircular arc design. Two smooth walls 122 are planar, with their sides smoothly connecting one side of the curved wall 121 and one side of the main cup housing 110, respectively, to ensure smooth interior surfaces for all three.

[0041] In some embodiments, the maximum distance between the expansion housing 120 and the rotation axis of the stirring assembly 200 is 1.2 to 2 times the minimum distance between the main cup housing 110 and the rotation axis. Figure 1 From a central perspective, the main cup housing 110 and the expansion housing 120 form a racetrack-like shape. The stirring assembly 200 is located at the center of one of the semicircles, meaning the rotation axis is coaxial with the center of the main cup housing 110. In the figure, R is the distance from the main cup housing 110 to the rotation axis, and D is the distance from the farthest point of the expansion housing 120 to the rotation axis.

[0042] In some embodiments, the cross-sectional shape of the cup cavity is a symmetrical figure along the radial direction of the rotation axis of the stirring assembly 200. The symmetry center is as follows: Figure 4a-4e Indicated by the dotted line. Figure 4aFor example, the two smooth walls are symmetrical with respect to the symmetry center, and the symmetry center passes through the middle of the main cup shell and the curved wall, dividing the main cup shell and the curved wall into two symmetrical parts. Figure 4c As shown, the cup body can also adopt a polygonal structure, and the arrangement of the stirring component therein, the dotted line part in the figure shows the part that the expansion shell adds compared to the traditional cup body shape. Figure 4d In an alternative embodiment, the cup body is a combination of polygons and arcs, in which the stirring assembly is arranged. Figure 4e In an alternative embodiment, an oval cup body and the arrangement of the stirring assembly therein are also shown.

[0043] In some embodiments, the main cup shell 110 and the expansion shell 120 are integrally formed. The cup body wall thickness is 1mm-4mm. Specifically, the cup body is manufactured using a high borosilicate blowing process, thus breaking away from the traditional die-cast glass process and achieving a thinner wall thickness.

[0044] In some embodiments, the cup body forms two opposing openings. The cup body also includes a bottom wall sealedly connected to one of the openings, while the other opening forms a cup opening. The blending cup also includes a cup lid assembly 300 that can be closed over the other opening. Figure 5 The bottom opening of the cup body shown in the figure features an annular inner rim with a stepped shape, which not only enhances the strength of the cup body but also provides a mounting base for the bottom wall. The bottom wall is made of a metal alloy, such as stainless steel, and has a through-hole in which a temperature sensor is installed for temperature detection. An electric heating element is also installed on the lower surface of the bottom wall. The bottom of the cup body also includes a bottom cover with an upwardly extending annular wall at its edge. The end of the annular wall is connected to the outer side of the lower end of the cup body, protecting the heating element and other components.

[0045] The food processor of this embodiment also includes a drive device, which is arranged in the cup cover assembly 300 or at the bottom of the cup body 100. The rotating shaft of the stirring assembly 200 is in transmission connection with the drive device. The drive device is generally a motor. If the drive device is arranged in the cup cover assembly 300, the stirring assembly 200 can be removed along with the cup cover assembly 300; if the drive device is arranged at the bottom of the cup body 100, the stirring assembly 200 is fixed in a corresponding position in the cup body, and the rotating shaft passes through the bottom wall of the cup bottom and is in transmission connection with the drive device. The figure shows a structure in which the drive device is arranged in the cup cover assembly 300.

[0046] In some embodiments, see Figure 2The food processor also includes a base 500. The base 500 houses a power supply assembly, which can be a battery or a circuit that connects to mains electricity and converts it into a power source for the drive unit. The blender cup is detachably connected to the base 500, with a wiring assembly provided at the connection. When the blender cup is connected to the base 500, the power supply assembly is electrically connected to the drive unit via the wiring assembly.

[0047] In some embodiments, see Figure 6 , the cup cover assembly 300 includes a cup cover body 310 and a feeding cover 320. The feeding cover 320 body can cover the cup mouth, and a lower edge is provided around the lower surface, which can be embedded in the cup mouth and matched with the inner wall of the cup mouth. A sealing ring is surrounded by the outer side of the upper end of the lower edge, and the sealing ring has a sealing strip to ensure that the lower edge is tightly connected to the inner wall of the cup mouth. A feeding port 311 is provided on the cup cover body 310. The feeding port 311 is located radially outside the rotating shaft of the stirring assembly 200, close to the expansion shell 120, and the feeding cover 320 is detachably mounted on the feeding port 311.

[0048] In some embodiments, see Figure 2 and Figure 6 The blender cup further includes a filter assembly 400. The filter assembly 400 is disposed around the surfaces of the main cup shell 110 and the expansion shell 120. An opening of the filter assembly 400 is pluggable and connected to the cup lid assembly 300. Specifically, the upper opening of the filter assembly 400 can be inserted and embedded in the outer side of the lower edge of the cup lid body 310 after insertion.

[0049] The upper opening of the filter assembly is provided with a positioning groove 220, and an elastic snap 230 is provided at the insertion point to prevent it from falling off. The cup cover assembly 300 is provided with a positioning protrusion 312 corresponding to the positioning groove 220. Specifically, the positioning protrusion 312 is provided on the outer surface of the lower edge of the feeding cover 320 body, and the outer surface of the lower edge is also provided with an annular groove. After the upper opening of the filter assembly 400 is inserted into the lower edge of the feeding cover 320 body, the protrusion of the elastic snap 230 facing the lower edge can be embedded in the annular groove to achieve a snap connection and prevent it from falling off.

[0050] In some embodiments, the filter assembly 400 has a plurality of flow ribs 410, which are arranged at intervals in the circumferential direction of the filter assembly. The area between two adjacent flow ribs 410 of the filter assembly 400 is provided with meshes.
