Description

Technical Field

[0001] This utility model relates to the field of food processor technology, and in particular to a food processor with a shaftless metal bucket. Background Technology

[0002] As the functions of food processors continue to increase, they are becoming increasingly popular among consumers. They use a main unit to drive a blade shaft, which in turn rotates the mixing blades to process ingredients. Based on the position of the blade shaft, food processors are divided into top-mounted and bottom-mounted types.

[0003] Food processors with a top-mounted blade shaft offer better sealing. However, this design also results in a higher center of gravity for the blade shaft, and the lack of bottom support makes it less stable. Some food processors use a cup shaft inside the container to connect the blades, but this structure is more complex and located inside the container, creating many hard-to-reach areas and making cleaning difficult.

[0004] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a food processor with a shaftless metal bucket to simplify the structure of the food processor.

[0006] The technical solution of this utility model is as follows:

[0007] The food processor with a shaftless metal bucket includes:

[0008] The bottom of the cup has a first groove.

[0009] A cup wall is provided around the bottom of the cup; a cavity is formed between the cup wall and the bottom of the cup; the first groove is provided in the cavity;

[0010] A blade shaft extends into the cavity from the end of the cup wall away from the bottom of the cup; the blade shaft is connected to the main unit, and a stirring blade is provided on the blade shaft;

[0011] Wherein, from the opening of the first groove to the bottom of the first groove, the cross-sectional area of ​​the first groove gradually decreases; the portion of the cutter shaft extending into the cavity extends into the first groove; the bottom of the cup is made of metal material.

[0012] A further technical solution is that the cutter shaft extends into the end surface of the first groove to form a second groove.

[0013] A further technical solution is that a limiting protrusion is provided on the bottom surface of the first groove and extends into the second groove.

[0014] A further technical solution is that, around the first groove, the bottom of the cup protrudes towards the cavity to form a raised surface.

[0015] A further technical solution is to provide a chamfer between the outer edge of the raised surface and the bottom of the cup without a raised surface for transition.

[0016] A further technical solution is that the end of the cup wall near the bottom of the cup extends towards the cavity side to form a rim; the bottom of the cup is connected to the rim.

[0017] A further technical solution is that the first groove is a rotating body formed around the axis of the cutter shaft.

[0018] A further technical solution is that a cup lid is provided at the end of the cup wall away from the bottom of the cup; the cup lid covers the cavity; a connecting hole is provided on the cup lid; and the cutter shaft extends into the cavity along the connecting hole.

[0019] A further technical solution is that the outer edge of the cup bottom is bent away from the cavity to form a flange; along the direction perpendicular to the cup bottom, the length of the flange beyond the cup bottom is greater than the height of the first groove rising from the cup bottom.

[0020] A further technical solution is that the outer edge of the flange, away from the cavity, is curled to form a curled portion.

[0021] The beneficial technical effects of this utility model are as follows:

[0022] (1) The shaftless metal bucket food processor of this utility model has a blade shaft connected to the main unit that extends into the cavity from top to bottom. The main unit drives the main unit to rotate, which can stir the ingredients in the cavity. The bottom of the cup is provided with a first groove, and the blade shaft extending into the cavity also extends into the first groove. When the main unit drives the blade shaft to rotate, the first groove can restrict the radial position of the blade shaft, thereby improving the stability of the blade shaft during rotation. When the main unit stops driving the blade shaft to rotate, the friction between the bottom of the cup and the blade shaft can also achieve quick stopping of the blade. The structure is simple, and the blade shaft can be disassembled and assembled by simply inserting or pulling the blade shaft into or out of the first groove, which is convenient for daily maintenance. Moreover, the area of ​​the first groove gradually decreases from the opening to the bottom, which reduces the contact area between the first groove and the blade shaft and reduces the friction between the bottom of the cup and the blade shaft. The blade shaft extending into the first groove is supported by the inclined side wall of the first groove. When the blade shaft is rotated, the inclined side wall of the first groove will provide an upward component force to the blade shaft. By utilizing the assembly error of the blade shaft or the elastic connection between the blade shaft and the main unit, the inclined sidewall of the first groove pushes the blade shaft upward, causing it to suspend on the surface of the cup bottom, significantly reducing the friction between the blade shaft and the cup bottom. The cup bottom is made of metal material, which also effectively improves the wear resistance of the cup bottom and extends the service life of the blender with the shaftless metal container.

[0023] (2) Further, the limiting protrusion extends into the second groove. When the cutter shaft rotates in the first groove, the first groove and the limiting protrusion cooperate to restrict the radial position of the cutter shaft, further reducing the radial swing of the cutter shaft and improving the stability of the cutter shaft during rotation.

[0024] (3) Furthermore, the raised surface raises the opening of the first groove, making it easier for ingredients to gather on the lower bottom of the cup, thereby reducing the accumulation of ingredients in the first groove. Attached Figure Description

[0033] Figure 1 A vertical cross-sectional view of a food processor with a shaftless metal bucket according to an embodiment of the present disclosure is shown.

[0034] Figure 2 An exploded view of the cup body and cup wall in a blender with a shaftless metal bucket according to an embodiment of this disclosure is shown. Please refer to... Figure 1 and Figure 2 The blender with a shaftless metal bucket includes a cup bottom 1 with a first groove 11. A cup wall 2 surrounds the cup bottom 1, forming a cavity 3 between the cup wall 2 and the cup bottom 1. The first groove 11 is located within the cavity 3. A blade shaft 5 extends into the cavity 3 from the end of the cup wall 2 away from the cup bottom 1. The blade shaft 5 is connected to the main unit 52; specifically, the blade shaft 5 and the main unit 52 can be connected via a diaphragm coupling to facilitate axial displacement of the blade shaft 5. A stirring blade 51 is mounted on the blade shaft 5. The main unit 52 is driven to rotate, thus blending the ingredients within the cavity 3.

[0035] In this design, the portion of the cutter shaft 5 extending into the cavity 3 extends into the first groove 11. When the main unit 52 drives the cutter shaft 5 to rotate, the first groove 11 restricts the radial position of the cutter shaft 5, thereby improving the stability of the cutter shaft 5 during rotation. When the main unit 52 stops driving the cutter shaft 5 to rotate, the friction between the cup bottom 1 and the cutter shaft 5 also enables rapid tool stop. This structure is simple; the cutter shaft 5 can be easily disassembled and assembled by simply inserting or removing it into the first groove 11, facilitating routine maintenance. From the opening of the first groove 11 to its bottom, the cross-sectional area of ​​the first groove 11 gradually decreases to reduce the contact area between the first groove 11 and the cutter shaft 5, thus reducing the friction between the cup bottom 1 and the cutter shaft 5. When the cutter shaft 5 extending into the first groove 11 is supported by the inclined sidewall of the first groove 11, rotating the cutter shaft 5 provides an upward component force to the cutter shaft 5 through the inclined sidewall of the first groove 11. By utilizing the assembly error of the blade shaft 5 or the elastic connection between the blade shaft 5 and the main unit 52, the inclined sidewall of the first groove 11 pushes the blade shaft 5 upward, causing the blade shaft 5 to suspend on the surface of the cup bottom 1, significantly reducing the friction between the blade shaft 5 and the cup bottom 1. The cup bottom 1 is made of metal material, which also effectively improves the wear resistance of the cup bottom 1 and extends the service life of the blender with the shaftless metal bucket.

[0036] In some embodiments, the cup bottom 1 undergoes electrolytic treatment to further enhance its wear resistance and extend the lifespan of the blender with the shaftless metal bucket. At this time, the cup bottom 1 and the cup wall 2 can be welded together. After electrolytic treatment, the cup bottom 1 is then welded to the cup wall 2, reducing the cost of the electrolytic treatment.

[0037] Figure 3 A schematic diagram of the vertical cross-sectional structure of the bottom of the cup in a blender with a shaftless metal bucket according to an embodiment of this disclosure is shown. Please refer to... Figure 1 and Figure 3 The cutter shaft 5 extends into the end surface of the first groove 11, forming a second groove 53. The second groove 53 prevents the end of the cutter shaft 5 from interfering with the bottom surface of the first groove 11. Additionally, a limiting protrusion 111 is provided on the bottom surface of the first groove 11, extending into the second groove 53. The first groove 11 and the limiting protrusion 111 cooperate to restrict the radial position of the cutter shaft 5, further reducing its radial oscillation and improving its stability during rotation.

[0038] Preferably, the first groove 11 is a rotating body formed around the axis of the cutter shaft 5 to circumferentially restrict the radial position of the cutter shaft 5 and reduce the radial swing of the cutter shaft 5.

[0039] Please refer to Figure 1 and Figure 2 Around the first groove 11, the bottom of the cup 1 protrudes towards the cavity 3 to form a raised surface 13. The raised surface 13 raises the opening of the first groove 11, making it easier for food to gather on the lower bottom of the cup 1, thereby reducing the accumulation of food at the first groove 11.

[0040] Preferably, a chamfer 131 is provided between the outer edge of the raised surface 13 and the non-raised bottom 1 of the cup for transition. The chamfer 131 can be a straight chamfer 131 or a rounded chamfer 131 to smooth the surface of the bottom 1 of the cup, making it easier for the food to slide along the bottom 1 of the cup and increasing the probability of the food colliding with the stirring blade 51.

[0041] More preferably, the cup wall 2 extends towards the cavity 3 from the end near the bottom of the cup 1, and is provided with a rim 21. The bottom of the cup 1 is connected to the rim 21. The rim 21 facilitates the connection between the bottom of the cup 1 and the cup wall 2, and at the same time increases the connection area between the bottom of the cup 1 and the cup wall 2, thereby increasing the connection strength and sealing performance between the bottom of the cup 1 and the cup wall 2.

[0042] Figure 4 A schematic diagram of the vertical cross-sectional structure of the bottom of the cup in a blender with a shaftless metal bucket according to an embodiment of this disclosure is shown. Please refer to... Figure 1 , Figure 2 and Figure 4A cup lid 4 is provided at the end of the cup wall 2 away from the cup bottom 1. The cup lid 4 covers the cavity 3. A connecting hole 41 is provided on the cup lid 4. The cutter shaft 5 extends into the cavity 3 along the connecting hole 41. The main unit 52 can be fixed on the cup lid 4. In some embodiments, a sealing ring 42 is provided between the cup lid 4 and the cup wall 2 to ensure the sealing performance between the cup lid 4 and the cup wall 2.

[0043] Preferably, the outer edge of the cup bottom 1 is bent away from the cavity 3 to form a flange 12, which supports the cup bottom 1 when it is placed. In the direction perpendicular to the cup bottom 1, the length of the flange 12 beyond the cup bottom 1 is greater than the height of the first groove 11 rising from the cup bottom 1, so as to prevent the first groove 11 from contacting the placement plane beyond the flange 12, which would affect the stability of the food processor with shaftless metal bucket when placed.

[0044] More preferably, the outer edge of the flange 12 away from the cavity 3 is curled to form a curled portion 121. When the flange 12 supports the cup bottom 1, the curled portion 121 contacts the placement plane, and the elastic deformation of the curled portion 121 itself can offset part of the supporting force.

[0045] In other embodiments, the outer edge of the cup bottom 1 is bent away from the cavity 3 to form a first bent portion 123. The outer edge of the first bent portion 123 is bent to form a support surface 122 parallel to the cup bottom 1. The outer edge of the support surface 122 is bent closer to the cavity 3 to form a second bent portion 124. When the cup bottom 1 is placed, the support surface 122 contacts the placement plane. Part of the support force is transmitted to the cup wall 2 along the first bent portion 123, and another part of the support force is transmitted to the cup wall 2 along the second bent portion. The first and second bent portions work together to support the cup bottom 1 and the cup wall 2.

[0046] The specific workflow of this utility model is as follows:

[0047] When the host 52 drives the cutter shaft 5 to rotate, the sidewall of the first groove 11 contacts and rubs against the end of the cutter shaft 5, limiting the radial sway of the cutter shaft 5 and ensuring the stability of the cutter shaft 5's rotation. At the same time, the inclined sidewall of the first groove 11 provides an upward component force to the cutter shaft 5. Utilizing the assembly error of the cutter shaft 5 or the elastic connection between the cutter shaft 5 and the host 52, the inclined sidewall of the first groove 11 pushes the cutter shaft 5 upward, causing the cutter shaft 5 to suspend on the surface of the cup bottom 1, significantly reducing the friction between the cutter shaft 5 and the cup bottom 1.

[0048] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0049] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
