Description

Technical Field

[0001] This utility model belongs to the field of mixer technology, and specifically relates to a mixer. Background Technology

[0002] A blender is a device for crushing and juicing fruits and vegetables. During use, the blender is held by hand, and the blade assembly of the blender is inserted into a cup. The blades in the blade assembly rotate to crush and juic the fruits and vegetables in the cup. The blender includes a blender body and a blade assembly connected to the blender body. In the prior art, the transmission parts of the two are connected by a fixed connection. This fixed connection is beneficial to its sealing performance, but it is not conducive to its assembly and disassembly.

[0003] In existing technologies, when juicing with a blender, the blade assembly has a flat end. Due to the negative pressure between the blade assembly and the cup, the blade assembly spontaneously adheres to the bottom of the cup during juicing, a phenomenon known as cup suction. Furthermore, if there are openings or uneven surfaces at the end of the blade assembly, the rotating liquid produced during juicing can cause the cup to rotate as it impacts the cup, resulting in cup movement and affecting the juicing operation.

[0040] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the specific implementation methods of this utility model will be described below with reference to the accompanying drawings. Obviously, the drawings described below are merely some embodiments of this utility model. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort.

[0041] The technical solution of this utility model will be described in detail below with specific embodiments.

[0042] Reference Figures 1 to 14 A mixer includes a mixer body 4 and a cutter head assembly connected to the mixer body 4. The mixer body 4 includes a housing 41 and a transmission assembly 42 disposed within the housing 41 and fitted with the cutter head assembly for transmission. The cutter head assembly and the transmission assembly 42 are connected by a fitting method, which is simple, occupies little space, and is conducive to assembly, disassembly, and maintenance.

[0043] The transmission assembly 42 includes a motor 421 and a transmission shaft 422 that is connected to the motor 421.

[0044] The cutter head assembly includes a cutter head 2 and a rotating shaft 20. The cutter head 2 is fixedly connected to the rotating shaft 20, which is engaged with the transmission shaft 422 for transmission. The connection between the rotating shaft 20 and the transmission shaft 422 is simple, the structure occupies little space, and it is convenient for assembly, disassembly, and maintenance.

[0045] A fitting sleeve 423 is provided at the end of the drive shaft 422, and a fitting block 201 is provided at the end of the rotating shaft 20 facing the drive shaft, which fits into the inner surface of the fitting sleeve 423. The drive shaft 422 and the rotating shaft 20 are connected by the mutual fitting of the fitting sleeve 423 and the fitting block 201, so that the cutter head assembly and the transmission assembly 42 are connected for transmission. This connection method is simple, and the connection is carried out by fitting. The structure occupies little space and is conducive to assembly, disassembly and maintenance.

[0046] Along the radial direction of the drive shaft 422, the inner surface of the fitting sleeve 423 has a polygonal cross-section, and the outer surface of the fitting block 201 has the same cross-sectional shape as the inner surface of the fitting sleeve 423. The cross-sections of the fitting sleeve 423 and the fitting block 201 can be polygons such as triangles, quadrilaterals, pentagons, or hexagons; in this embodiment, they are hexagons. Connecting the rotating shaft 20 and the drive shaft 422 through mutually compatible shapes provides high stability, reduces the likelihood of loosening and affecting transmission performance, and the fitting method results in a small structural footprint, facilitating assembly, disassembly, and maintenance.

[0047] The cutter head assembly also includes a stirring base 1, and the cutter head 2 is movably disposed inside the stirring base 1. The stirring base 1 has a cavity 10 inside to provide rotation space for the cutter head 2; the rotating shaft 20 is movably connected to the stirring base 1. The cutter head 2 is connected to the rotating shaft 20 and connected to the stirring base 1 through the rotating shaft 20, so that the cutter head 2 can rotate within the stirring base 1.

[0048] The stirring base 1 and the housing 41 are threaded together. The connection between the two modules by means of threads is simple and easy to implement, and this connection method is also conducive to assembly, disassembly and maintenance.

[0049] The stirring base 1 has a communication structure above the blade head 2 that connects to the cavity 10. This communication structure above the blade head 2 provides a channel for liquid flow during the blade assembly's operation within the cup, thereby reducing the negative pressure exerted on the cup by the blade assembly and preventing the cup from being sucked up. As the blade head 2 rotates, the liquid rotates with it. The communication structure above the blade head 2 prevents the rotating liquid from impacting the inner wall of the cup in the radial direction, thus preventing the cup from moving during blade assembly operation.

[0050] In the radial direction of the rotation of the blade head 2, the projection surface of the connecting structure does not overlap with the projection surface of the blade head 2. The connecting structure is positioned above the blade head 2 on the stirring base 1, and the stirring base 1 has no holes at the blade head 2 location. The connecting structure's placement above the blade head 2 prevents the rotating liquid from impacting the inner wall of the cup in the radial direction, thus avoiding the cup moving during blade head assembly operation.

[0051] The stirring seat 1 includes a first seat body 11 and a second seat body 12 arranged in sequence;

[0052] The connecting structure is disposed on the first seat 11, and the cavity 10 is disposed within the second seat 12. In the radial direction of the blade head 2's rotation, the projection surface of the first seat 11 does not overlap with the projection surface of the blade head 2. The first seat 11 has the connecting structure and is located above the blade head 2, while the second seat 12 is disposed below it. The second seat 12 contains the cavity 10, which provides space for the blade head 2 to rotate, thus providing a corresponding liquid flow channel at the first seat 11. After the blade head 2 rotates within the second seat 12, the liquid flows through the cavity 10 to the connecting structure, providing a flow channel and reducing the negative pressure generated by the blade head assembly on the cup, preventing the cup from being sucked up. During the blade head's rotation, the liquid rotates with the blade head 2. The second seat 12 does not have any holes, preventing the rotating liquid from impacting the inner wall of the cup in the radial direction, thus preventing the cup from moving during blade head assembly operation.

[0053] The communication structure includes a first communication port 31 disposed around the first base 11 and a second communication port 32 disposed inside the first base 11;

[0054] The first connecting port 31, the second connecting port 32, and the cavity 10 are interconnected. In the radial direction of the rotation of the cutter head 2, neither the first connecting port 31 nor the second connecting port 32 overlaps with the projection surface of the cutter head 2. The first connecting port 31 is provided on the first seat 11, and the second connecting port 32 is provided inside the first seat 11, so that liquid can flow through the connected cavity 10 to the second connecting port 32 and the first connecting port 31, providing a channel for liquid flow, thereby reducing the negative pressure generated by the cutter head assembly on the cup and avoiding the problem of the cup being sucked up. At the same time, no holes are provided at the second seat 12 to prevent the rotating liquid from impacting the inner wall of the cup in the radial direction, thereby avoiding the problem of the cup moving with the cutter head assembly during operation.

[0055] The projection of the first connecting port 31 through the second connecting port 32 through the second connecting port 32 is perpendicular to each other. This allows liquid to be vertically transported through the cavity 10 to the second connecting port 32, and then transported through the second connecting port 32 to the first connecting port 31.

[0056] The openings of the first connecting port 31 and the second connecting port 32 can be any one of the following shapes: circular, square, trapezoidal, rounded square, rounded trapezoidal, or triangular. The shape of the openings can be adjusted according to the amount of liquid flowing through.

[0057] One or more of the first communication ports 31 are provided on the circumferential sidewall of the first base body 11;

[0058] One or more second connecting ports 32 are provided within the first base 11. Multiple first connecting ports 31 are arranged in a circular array centered on the axis of the first base 11, or multiple ports are arranged at unequal intervals; multiple sets of second connecting ports 32 are arranged concentrically in a circular array centered on the axis of the first base 11. The number of ports is adjusted according to the liquid flow rate.

[0059] A first block 13 is disposed within the first base 11, and the first block 13 is located above the cavity 10. The second connecting port 32 is disposed through the first block 13. The rotating shaft 20 is movably connected to the first block 13; specifically, the first block 13 is provided with a first bearing 131 movably connected to the rotating shaft 20; wherein the first block 13 is located at the junction of the first base 11 and the second base 12. The rotating shaft 20 is movably connected to the first block 13 via the first bearing 131, allowing the cutter head to rotate within the second base 12.

[0060] The opening of the second seat 12 is a flat surface; along the radial direction of rotation of the cutter head 2, the projections of the openings of the second seat 12 overlap and lie on the same horizontal plane; the radial area of ​​the first seat 11 along its axis is smaller than the radial area of ​​the second seat 12 along its axis; the first seat 11, the second seat 12, and the cutter head 2 are all coaxially arranged; the rotating shaft 20 is connected to the motor drive. It is understood that the cutter head assembly is integrated into the mixer. In this technical solution, a threaded connection is used, but alternatively, snap-fit, welding, or glue connection methods can be used.

[0061] A second block 43 is fixedly installed inside the housing 41. The second block 43 is provided with a second bearing 44 that is movably connected to the drive shaft 422. The drive shaft 422, the second bearing 44, and the second block 43 are connected layer by layer from the inside out. Specifically, the second plate is fixedly connected to the connecting post provided inside the housing 41 by screws. The second plate is provided with one or more reinforcing ribs. The drive shaft 422, the second bearing 44, the second block 43, and the rotating shaft 20 are all coaxially arranged. The second bearing 44 is provided, and the fitting sleeve 423 and the fitting block 201 are located between the first plate 13 and the second block 43 in the axial direction of the drive shaft 422. This keeps the fitting position limited to the line connecting the first bearing 131 and the second bearing 44, and keeps the fitting position coaxial with the drive shaft 422 and the rotating shaft 20. This avoids the problem of shaking or skewing at the fitting connection during operation, which would affect the stability of the operation.

[0062] 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.
