Technical Field
[0001] This invention relates to the field of food mixers, specifically to a horizontally adjustable eccentric food mixer. Background Technology
[0002] Some existing food mixers use eccentrically arranged mixing heads to enhance the tumbling and shearing effect of materials. However, this eccentric structure is usually fixed and cannot be adjusted in the horizontal direction. This causes the mixing effect to be mainly concentrated in the central area of the container, making it difficult to effectively reach the edge areas and easily creating mixing dead zones.
[0003] Meanwhile, when users change to mixing containers of different capacities or diameters, the mixing head with a fixed eccentricity cannot adjust the mixing range according to the container size. If the eccentricity is too large, it is easy to hit the inner wall of the container, and if it is too small, the material at the edge will not be mixed sufficiently, affecting the overall processing quality.
[0004] More seriously, this type of eccentric stirring head structure has mechanical defects under high-speed eccentric operation: on the one hand, the contact part of the eccentric stirring head structure and the limiting part are in sliding friction, which is prone to wear, jamming and other phenomena, and can easily lead to greater vibration and noise of the whole machine; on the other hand, in the existing fixed eccentric structure, the stirring head and its radial positioning parts are mostly in sliding contact, which causes greater wear and higher vibration and noise under long-term high-speed eccentric operation, further affecting the stability of the equipment operation and service life.
[0005] Therefore, there is a need for a horizontally adjustable eccentric food mixer that can flexibly adjust the position of the mixing head in the horizontal radial direction according to the size of the mixing container, thereby dynamically optimizing the eccentricity, effectively expanding the mixing coverage, eliminating the mixing dead angle at the edge of the container, and solving the shortcomings of the existing fixed eccentric structure in terms of mixing uniformity. Summary of the Invention
[0006] This invention addresses the problems existing in the prior art by providing a horizontally adjustable eccentric food mixer. By using centrifugal force to drive the slider to move outward, and in conjunction with an adjustable limiting ring and a compression spring, the eccentricity of the mixing head can be adaptively adjusted, precisely matching different mixing containers and improving mixing uniformity and equipment versatility.
[0007] To address the problems of existing technologies, this invention provides a horizontally adjustable eccentric food mixer, comprising a base and a mixer head disposed thereon. The base has a mixing container located below the mixer head. The mixer head has a rotating disk, and a mixing head extending into the mixing container is eccentrically mounted on the lower end face of the rotating disk. The invention also includes a horizontal adjustment mechanism disposed on the mixer head for adjusting the radial position of the mixing head on the rotating disk. The horizontal adjustment mechanism includes a slide rail fixedly disposed radially on the lower end face of the rotating disk, and a slider slidably disposed on the slide rail. The stirring head is mounted vertically on the slider. During the rotation of the rotating disk, the stirring head is subjected to a centrifugal force along the slide rail. A limiting component is provided on the machine head to limit the position of the slider in the radial direction of the rotating disk. The limiting component includes a limiting ring and a lifting adjustment component connected to it in a transmission manner. The limiting ring is coaxially arranged with the rotating disk. The inner side of the limiting ring is provided with an inwardly inclined annular conical surface. The slider is provided with a contact part that abuts against the annular conical surface. When the limiting ring adjusts its axial position, the slider is in a radial adjustment state.
[0008] Preferably, a fixed block is provided on the rotating disk along the slide rail direction, and a protrusion is provided on the top of the slider outside the fixed block. A compression spring is provided between the fixed block and the protrusion to maintain a continuous contact force between the contact part and the annular conical surface.
[0009] Preferably, the upper end of the stirring head is rotatably mounted on the slider via a bearing.
[0010] Preferably, the upper end of the stirring head is fitted with a ring sleeve, and the ring sleeve is uniformly provided with a plurality of contact portions along its circumference. When the contact portions abut against the annular conical surface, the contact portions are in a synchronous abutting state.
[0011] Preferably, both the abutting part and the contact part are ball bearing structures that roll in contact with the annular conical surface, together forming a multi-point rolling support structure. The outer wall of the slider is provided with a ball bearing seat for mounting the abutting part, and the outer circumferential surface of the ring is provided with a ball bearing groove for mounting the contact part.
[0012] Preferably, the inner side of the limiting ring is provided with a wear-resistant layer, and the surface of the wear-resistant layer forms the annular conical surface, which is used to reduce wear on the contact part and the contact part.
[0013] Preferably, the wear-resistant layer is made of a wear-resistant elastic material to provide a cushioning effect when the stirring head vibrates.
[0014] Preferably, the lifting adjustment component includes a fixed collar and a rotating collar. The fixed collar is fixedly installed on the machine head and is coaxially arranged with the limiting ring. The fixed collar has an external thread, and the rotating collar has an internal thread. The rotating collar is threaded onto the fixed collar, and the lower end of the rotating collar is fixedly connected to the limiting ring.
[0015] Preferably, the outer circumference of the rotating collar is provided with a rotating handle to facilitate manual operation of the rotating collar by the user.
[0016] Preferably, the machine head is provided with a scale indicator mechanism that cooperates with the rotating collar to display different eccentricity levels corresponding to the axial position of the limiting ring.
[0017] The advantages of this application compared to the prior art are: 1. This invention uses a slide rail and a slider on a rotating disk, with the stirring head mounted on the slider. During rotation, centrifugal force causes the stirring head to automatically offset outward. A lifting adjustment component moves the limiting ring axially, changing the contact position between its inner annular conical surface and the contact part on the slider, thus precisely setting the eccentricity of the stirring head. The compression spring between the stationary block and the protrusion consistently provides outward elastic thrust, ensuring the contact part remains tightly against the annular conical surface, maintaining stable constraint. The overall structure achieves adaptive adjustment of the eccentric position, adjusting the stirring coverage of the stirring head according to the capacity of the mixing container, improving mixing uniformity and equipment versatility.
[0018] 2. This invention achieves stable radial constraint on the stirring head by providing abutment and contact parts on the slider and ring respectively, both of which are ball bearing structures. These parts form multi-point rolling support with the annular conical surface inside the limiting ring. Under the thrust of the compression spring, the stirring head maintains rolling contact with the annular conical surface, effectively reducing frictional resistance and improving smooth operation. This not only reduces wear during long-term operation but also absorbs vibration energy, providing a buffering effect and maintaining continuous contact between the ball bearing structure and the annular conical surface. This enhances the stability, durability, and low-noise performance of the stirring head under high-speed eccentric stirring.
[0019] 3. This invention achieves precise control of the eccentricity through a threaded lifting adjustment mechanism. The user grips the rotating handle, causing the rotating collar to rise and fall axially along the fixed collar, thereby driving the limiting ring to move synchronously. The annular conical surface inside the limiting ring engages with the contact part on the slider, maintaining contact under the continuous thrust of the compression spring, automatically adjusting the radial position of the slider as the limiting ring rises and falls. This achieves bidirectional continuous adjustment of the eccentricity, allowing the user to quickly switch between eccentric gears simply by rotating the lifting adjustment mechanism in the forward and reverse directions. Simultaneously, the scale indicator mechanism provides intuitive and visual feedback on the gear position through the cooperation of the pointer and scale lines, improving the mixer's applicability to different mixing containers.

Detailed Implementation
[0034] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.
[0035] See Figures 1 to 8 As shown, a horizontally adjustable eccentric food mixer includes a base 1 and a head 2 mounted thereon. A mixing container 3 is located below the head 2 on the base 1. A rotating disk 21 is mounted on the head 2, and a mixing head 4 extending into the mixing container 3 is eccentrically mounted on the lower end face of the rotating disk 21. A horizontal adjustment mechanism 5 is also included, mounted on the head 2, for adjusting the radial position of the mixing head 4 on the rotating disk 21. The horizontal adjustment mechanism 5 includes a slide rail 51, fixedly mounted radially on the lower end face of the rotating disk 21. A slider 52 is slidably mounted on the slide rail 51. The mixing head 4 is mounted vertically on the slider 52. During the rotation of the rotating disk 21, the mixing head 4 is subjected to a centrifugal force outward along the slide rail 51 along with the slider 52. A limiting component is also provided on the head 2 to limit the radial position of the slider 52 on the rotating disk 21. The limiting component includes a limiting ring 53 and a lifting adjustment component 54 connected to it in a transmission manner. The limiting ring 53 is coaxially arranged with the rotating disk 21. The inner side of the limiting ring 53 is provided with an inwardly inclined annular conical surface. The slider 52 is provided with an abutting part 521 that abuts against the annular conical surface. When the limiting ring 53 adjusts its axial position, the slider 52 is in a radial adjustment state.
[0036] The machine head 2 is equipped with a rotary driver for driving the rotary disk 21, and the rotary disk 21 is coaxially provided with a rotary shaft 211 that is connected to the rotary driver for transmission.
[0037] The slide rail 51 has a strip-shaped opening 511 on its side along its extension direction, and the slider 52 is provided with a sliding shaft 512. The sliding shaft 512 passes through the strip-shaped opening 511 and slides along its length direction to stabilize the movement of the slider 52.
[0038] The top of the mixing container 3 is provided with a protective cover 31 to prevent materials from splashing during the mixing process.
[0039] When using the food mixer, first place the ingredients to be mixed into the mixing container 3 located on the base 1, and cover it with the protective cover 31 to prevent the materials from splashing during the mixing process. Then start the rotary drive inside the machine head 2. The rotary drive drives the rotating shaft 211 to rotate through the transmission connection. The rotating shaft 211 is coaxial with the rotating disk 21, thereby driving the rotating disk 21 to rotate synchronously.
[0040] After the rotating disk 21 starts to rotate, since the stirring head 4 is mounted on the slide rail 51 arranged radially along the rotating disk 21 via the slider 52, the entire stirring head 4, along with the slider 52, is subjected to a centrifugal force outward along the slide rail 51, and has a tendency to slide outward. The slider 52 can slide freely on the slide rail 51, and its direction of movement is strictly limited to the radial direction of the rotating disk 21, driving the stirring head 4 to rotate eccentrically to mix the material in the mixing container 3.
[0041] To adjust the radial position of the slider 52, a limiting component is used to control it. When the operator adjusts the axial position of the limiting ring 53 through the lifting adjustment component 54, the relative mating point between the annular conical surface and the contact part 521 changes, thereby changing the outermost radial position that the slider 52 can reach under centrifugal force, thus adjusting the eccentricity of the stirring head 4.
[0042] As the slider 52 slides along the slide rail 51, its sliding shaft 512 passes through a slot 511 on the side of the slide rail 51 along the track direction, and moves synchronously with the slider 52 along the length of the slot 511. This ensures that the slider 52 remains stably guided when subjected to centrifugal force, prevents it from swaying or detaching from the slide rail 51 during high-speed rotation, and guarantees the reliability of radial movement.
[0043] As rotation continues, the stirring head 4, positioned at a set eccentric angle, performs off-center mixing of the material within the mixing container 3, expanding the mixing coverage area. Throughout the entire operation, the position of the stirring head 4 is achieved through the combined action of centrifugal force and the limiting components, realizing the enhanced mixing effect of eccentric stirring and meeting efficient operation requirements under different mixing needs.
[0044] See Figure 3 , Figure 5 and Figures 11 to 13 As shown, a fixed block 22 is provided on the rotating disk 21 along the slide rail 51. A protrusion 23 located outside the fixed block 22 is provided on the top of the slider 52. A compression spring 24 is provided between the fixed block 22 and the protrusion 23 to maintain the continuous contact force between the contact part 521 and the annular conical surface.
[0045] During the rotation of the rotating disk 21, the slider 52 moves outward along the slide rail 51 under centrifugal force, causing the protrusion 23 on its top to move outward synchronously. Since the fixed block 22 is fixedly mounted on the rotating disk 21 and located inside the protrusion 23, the compression spring 24 installed between the fixed block 22 and the protrusion 23 remains in a pre-compressed state, always applying an outward elastic thrust to the slider 52. This thrust causes the slider 52 to continuously press against the limiting ring 53, so that the contact part 521 on the slider 52 is always in close contact with the annular conical surface inside the limiting ring 53, maintaining stable contact and continuous contact force between the two, thereby limiting the eccentric position of the stirring head 4.
[0046] See Figure 3 , Figure 5 and Figure 10 As shown, the upper end of the stirring head 4 is rotatably mounted on the slider 52 via a bearing 41.
[0047] During the stirring process, the upper end of the stirring head 4 is rotatably mounted on the slider 52 via the bearing 41, so that the stirring head 4 can rotate freely around its own vertical axis while rotating eccentrically.
[0048] When the stirring head 4 is inserted into the material and encounters uneven resistance, the resistance is converted into torque, which drives the stirring head 4 to rotate independently relative to the slider 52. This effectively reduces the impact load during the stirring process, making the stirring action more gentle and smooth, and improving the mixing uniformity of ingredients with different viscosity or granular form.
[0049] See Figure 3 , Figure 5 , Figure 9 and Figure 10 As shown, the upper end of the stirring head 4 is fitted with a ring sleeve 42, and the ring sleeve 42 is uniformly provided with a plurality of contact portions 421 along its circumference. When the contact portion 521 abuts against the annular conical surface, the contact portion 421 is in a synchronous abutting state.
[0050] As the stirring head 4 moves radially along with the slider 52 and slides outward under centrifugal force, the contact portion 521 on the slider 52 abuts against the annular conical surface inside the limiting ring 53, thereby radially positioning the slider 52. Simultaneously, the ring sleeve 42, fitted onto the upper end of the stirring head 4, moves synchronously with the stirring head 4. Among its multiple circumferentially distributed contact portions 421, the outermost contact portion 421 abuts against the annular conical surface synchronously, enhancing the stability and vibration resistance of the stirring head 4 under eccentric working conditions.
[0051] See Figure 3 , Figure 5 , Figure 9 and Figure 10As shown, both the abutting part 521 and the contact part 421 are ball bearing structures that roll in contact with the annular conical surface, together forming a multi-point rolling support structure. The outer wall of the slider 52 is provided with a ball bearing seat 522 for mounting the abutting part 521, and the outer circumferential surface of the ring sleeve 42 is provided with a ball bearing groove for mounting the contact part 421.
[0052] During the operation of the mixer, the contact part 521 forms rolling contact with the annular conical surface inside the limiting ring 53. Simultaneously, the contact part 421 also rolls against the annular conical surface. The two sets of ball bearing structures, namely the contact parts 521 and 421, form a multi-point rolling support distributed at intervals on the annular conical surface, together constituting a stable upper and lower rolling constraint system. This not only effectively transmits radial positioning force but also reduces frictional resistance during the eccentric rotation of the mixing head 4, preventing jamming and improving the smoothness of the overall movement.
[0053] See Figure 3 and Figure 5 As shown, the inner side of the limiting ring 53 is provided with a wear-resistant layer 531, and the surface of the wear-resistant layer 531 forms the annular conical surface, which is used to reduce wear with the contact part 521 and the contact part 421.
[0054] During the stirring process, when the slider 52 is subjected to centrifugal force, the abutment portion 521 on it and the contact portion 421 on the ring sleeve 42 maintain rolling contact with the annular conical surface inside the limiting ring 53. To reduce wear caused by long-term friction, a wear-resistant layer 531 is provided on the inner side of the limiting ring 53. When the abutment portion 521 and the contact portion 421 roll along the annular conical surface, the wear-resistant layer 531, through its high wear resistance, inhibits surface damage, thereby ensuring that the multi-point rolling support structure maintains smooth rotation during high-speed operation.
[0055] See Figure 3 and Figure 5 As shown, the wear-resistant layer 531 is made of wear-resistant elastic material and is used to provide a buffering effect when the stirring head 4 vibrates.
[0056] During the mixing process, the mixing head 4 vibrates due to material resistance or high-speed rotation. At this time, the wear-resistant layer 531 on the inner side of the limiting ring 53 absorbs vibration energy through the elastic deformation of the material itself while rolling contacting the contact part 521 and the contact part 421. This effectively buffers the contact stress and provides a buffering effect, which not only effectively maintains the continuous fit between the ball structure and the annular cone surface, but also reduces operating noise, thereby ensuring that the multi-point rolling support structure maintains a stable fit with the annular cone surface during high-speed operation.
[0057] See Figure 3 , Figure 5 , Figure 9 and Figure 10As shown, the lifting adjustment component 54 includes a fixed collar 541 and a rotating collar 542. The fixed collar 541 is fixedly installed on the machine head 2 and is coaxially arranged with the limiting ring 53. The fixed collar 541 is provided with external threads, and the rotating collar 542 is provided with internal threads. The rotating collar 542 is threaded onto the fixed collar 541, and the lower end of the rotating collar 542 is fixedly connected to the limiting ring 53.
[0058] When adjusting the eccentricity of the stirring head 4, the user rotates the rotating collar 542 in the lifting adjustment component 54. Since the rotating collar 542 is threaded onto the external thread of the fixed collar 541 fixed on the machine head 2 through its internal thread, and the two are arranged coaxially, the rotating collar 542 generates axial displacement along the threaded pair of the fixed collar 541 when it rotates circumferentially. Furthermore, since the lower end of the rotating collar 542 is fixedly connected to the limiting ring 53, its axial movement directly drives the limiting ring 53 to rise and fall synchronously.
[0059] As the limiting ring 53 rises or falls axially, the position of its inner annular conical surface relative to the contact part 521 on the slider 52 changes. Under the force of the compression spring 24, the contact part 521 always remains in contact with the annular conical surface, thereby adjusting the radial limit position that the slider 52 can reach under centrifugal action and realizing the precise adjustment of the eccentricity of the stirring head 4.
[0060] When the rotating collar 542 is rotated upward, it rises along the external thread of the fixed collar 541, causing the limiting ring 53, which is fixedly connected to it, to move upward synchronously. Since the annular cone surface on the inner side of the limiting ring 53 is inclined inward, its upward movement reduces the diameter of the annular cone surface at the axial position. Thus, through the rolling contact between the annular cone surface and the contact part 521, the slider 52 is pushed inward, i.e., towards the rotation center. At this time, the compression spring 24 is further compressed, causing the slider 52 to move inward along the slide rail 51, and the eccentricity of the stirring head 4 decreases.
[0061] Conversely, when the rotating collar 542 is rotated downwards, the limiting ring 53 moves downwards accordingly, and the diameter of the annular cone surface increases at the point where it descends in the axial position. Since a compression spring 24 is provided between the slider 52 and the stationary block 22, an outward pushing force is always applied to the slider 52, causing the contact part 521 to remain tightly against the annular cone surface. As the limiting ring 53 moves downwards, the preload of the compression spring 24 is released, pushing the slider 52 to move outwards along the slide rail 51, thereby causing the stirring head 4 to shift outwards, increasing its eccentricity.
[0062] See Figure 9 and Figure 10 As shown, a rotating handle 5421 is provided on the outer periphery of the rotating collar 542 to facilitate manual operation of the rotating collar 542 by the user.
[0063] When adjusting the eccentricity of the stirring head 4, the user holds the rotating handle 5421, which is fitted around the outer circumference of the rotating collar 542. By applying a circumferential torque, the user drives the rotating handle 5421 to rotate, which in turn drives the rotating collar 542 to move in a spiral motion around the external thread of the fixed collar 541. Through the lifting and lowering stroke of the rotating collar 542, the axial position of the limiting ring 53 can be easily adjusted, thereby achieving a quick setting of the eccentricity of the stirring head 4.
[0064] See Figure 2 , Figure 4 , Figure 9 and Figure 10 As shown, the machine head 2 is provided with a scale indicator mechanism that cooperates with the rotating collar 542, which is used to display different eccentricity levels corresponding to the axial position of the limit ring 53.
[0065] The scale indicator mechanism includes a scale line on the upper circumference of the fixed collar 541 and a pointer on the outer circumference of the rotating collar 542. When the rotating collar 542 rotates, the pointer rotates synchronously with it and points to the corresponding scale line to intuitively display the current eccentricity setting of the stirring head 4.
[0066] When adjusting the eccentricity, the user rotates the rotating collar 542, causing the pointer fixedly connected to it to rotate synchronously around the fixed collar 541. Since the fixed collar 541 has circumferential graduations on its upper end, and the pointer is located on the outer circumference of the rotating collar 542, as the rotating collar 542 moves up and down along the thread and rotates, the pointer always points to the corresponding graduation. These graduations are pre-calibrated for different eccentricity levels, allowing the user to visually determine the current axial position of the limiting ring 53 and the corresponding eccentricity of the stirring head 4 by observing the graduation indicated by the pointer, thus achieving precise and visual adjustment.
[0067] This invention utilizes a radial slide rail 51 and a slider 52 mounted on a rotating disk 21. The stirring head 4 is mounted on the slider 52, causing it to automatically shift outward under centrifugal force during rotation. A lifting adjustment component 54 drives the limiting ring 53 to move axially, changing the engagement position between its inner annular conical surface and the contact portion 521 of the slider 52, thereby setting the eccentricity of the stirring head 4. The compression spring 24 between the fixed block 22 and the protrusion 23 continuously provides elastic thrust, ensuring the contact portion 521 maintains continuous contact with the annular conical surface, thus maintaining stable constraint.
[0068] Meanwhile, both the abutment part 521 on the slider 52 and the contact part 421 on the ring sleeve 42 are ball bearing structures, forming multi-point rolling support with the annular conical surface. This reduces frictional resistance, absorbs vibration, and reduces wear, ensuring stable operation and low noise performance under high-speed eccentric stirring.
[0069] During the axial movement of the adjusting limit ring 53, the user rotates the rotating collar 542 by rotating the handle 5421, which drives the limit ring 53 to rise and fall using the threaded pair. Its upward movement reduces the diameter of the annular cone surface at the axially elevated position, causing the slider 52 to move inward and the eccentricity to decrease. Conversely, its downward movement increases the diameter of the annular cone surface at the axially lowered position, causing the slider 52 to move outward and the eccentricity to increase. Combined with the scale indicator mechanism consisting of a pointer and graduations, the current eccentricity setting can be read intuitively, enabling quick and visual adjustment and effectively adapting to the size and stirring requirements of different mixing containers 3.
[0070] The above embodiments only illustrate one or more implementations of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of protection of the present invention. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the present invention, and these all fall within the scope of protection of the present invention.
