SUMMARY

[0003] In order to overcome the defects and deficiencies in the prior art, the purpose of the utility model is to provide a paste machine for food material heating and stirring.

[0004] In order to achieve the above purpose, the utility model relates to a paste machine for food material heating and stirring, which comprises a base, an operation panel arranged on the base, a pot body assembly, a heating assembly and a stirring driving assembly, an inner container arranged in the pot body assembly for containing food materials, a stirring shaft rotatably arranged in the inner container, a cover assembly detachably connected with the pot body assembly, the operation panel is electrically connected with the stirring driving assembly and the heating assembly, the pot body assembly and the cover assembly are detachably connected to position the inner container between them, the stirring shaft is arranged in the inner container to stir the food materials, and the heating assembly heats the inner container to heat the food materials contained therein.

[0005] The overall structure comprises a base, an operation panel, a pot body assembly and the like complete components. The operation panel is electrically connected with a stirring driving assembly and a heating assembly, so that convenient control of stirring and heating can be realized, the convenience of use operation is improved, and the needs of users for easy regulation and control of food processing are met. Secondly, the pot body assembly and the cover body assembly are detachably connected and can position the inner container. The inner container is used for containing food materials. The detachable design facilitates the removal and installation of the inner container, facilitates the cleaning of the inner container, ensures the hygiene of the food processing process, and the inner container is stably positioned, so that the displacement of the inner container during food processing can be avoided to affect the effect. Thirdly, the stirring shaft is rotatably arranged in the inner container to stir the food materials. The heating assembly heats the food materials through the inner container. The two cooperate to realize the synchronous stirring and heating of the food materials, so that the food materials can be uniformly and fully heated and mixed, the quality of the paste food materials is improved, the requirements of users for the taste and cooking degree of the food materials are met, and the overall design takes into account the practicability, convenience and hygiene, and is suitable for daily food heating and stirring.

[0006] Further, the stirring shaft is provided with a first stirring protrusion and a second stirring protrusion. The first stirring protrusion is a circular ring structure, and the second stirring protrusion is a circular cone structure. The first stirring protrusion to the second stirring protrusion is an arc structure with a decreasing radius.

[0007] The stirring protrusion structure design fully considers the comprehensiveness of food stirring. The first stirring protrusion with a circular ring structure can fully stir the upper layer of food materials in the container, and the second stirring protrusion with a circular cone structure can stir the lower layer of food materials, avoiding the deposition of food materials at the bottom. The arc transition design with a decreasing radius enables the food materials to flow smoothly along the arc surface when the stirring shaft rotates, reduces the stirring resistance, reduces the motor load, and prolongs the service life of the equipment. At the same time, the cooperation of the two protrusions with different structures can form a three-dimensional stirring space, so that the food materials can be mixed by rolling up and down in the container, effectively preventing insufficient stirring of local food materials and improving the stirring uniformity.

[0008] Further, the stirring shaft is provided with a first protruding rib, a second protruding rib and a stirring blade. The stirring blade is arranged on the first protruding rib, the second stirring protrusion is provided with the second protruding rib, and the length extension directions of the two protruding ribs and the axis direction of the stirring shaft are cross arranged. The first protruding rib is arranged on the first stirring protrusion, the second protruding rib is arranged on the second stirring protrusion, and the slope of the first protruding rib relative to the axis of the stirring shaft is greater than the slope of the second protruding rib.

[0009] The combination of the first and second convex ribs and the stirring blade can act on the food materials from multiple dimensions. The stirring blade relies on the first convex rib to enhance the cutting and stirring ability of the food materials, avoids the formation of food material clusters, and improves the stirring fineness. The length extension directions of the two convex ribs intersect with the axis of the stirring shaft, breaking the single stirring track, forming a more complex flow path in the inner container, and reducing the stirring blind area. The slope of the first convex rib relative to the axis of the stirring shaft is greater than that of the second convex rib, which can adapt to the state of the food materials in different areas of the inner container. The upper convex rib with a large slope can more powerfully stir the food materials with strong fluidity, and the lower convex rib with a small slope can stably stir the food materials that are prone to deposition, realizing efficient and uniform stirring and protecting the quality of the paste food materials.

[0010] Further, the stirring driving assembly includes a rotating shaft, a motor structure, a brake structure and a worm gear structure arranged on the rotating shaft; the rotating shaft and the worm gear structure are rotationally supported on the support plate body; the motor structure is used to drive the rotating shaft to rotate; the brake structure is used to brake the rotating shaft; and the worm gear of the worm gear structure is coaxially connected with the stirring shaft.

[0011] The combination of the motor, the brake and the worm gear structure of the stirring driving assembly ensures the stable operation of the stirring system. The motor structure provides sufficient power for the rotation of the rotating shaft, ensuring that the stirring shaft can drive the stirring convex to efficiently stir the food materials. The brake structure can quickly brake the rotating shaft when the equipment stops working, avoiding the safety hazard caused by the continuous rotation of the stirring shaft due to inertia, and facilitating the user to timely take out the inner container. The worm gear structure has the characteristics of stable transmission and low noise, can stably transmit the power of the motor to the stirring shaft, reduces vibration, and improves the quietness of the equipment operation. The rotating shaft and the worm gear structure are rotationally supported on the support plate body, enhancing the structural stability of the driving assembly and prolonging the service life.

[0012] Further, the stirring blade has a horizontal leaf part and a vertical leaf part, the horizontal leaf part is arc-shaped, the horizontal leaf part and the vertical leaf part jointly form an L shape, and a sawtooth structure is arranged in the width direction of the stirring blade.

[0013] The horizontal leaf part and the vertical leaf part of the L-shaped stirring blade can stir the food materials in the horizontal and vertical directions respectively, expand the stirring range, and reduce the stirring dead angle. The horizontal leaf part is arc-shaped, which can more smoothly push the food materials to flow during rotation, reduce the resistance, and enhance the shear force on the food materials. The sawtooth structure in the width direction can effectively cut the food materials, and for hard or blocky food materials, it can quickly stir them, improving the fineness of the food materials. This blade structure combines the functions of stirring and cutting, so that the paste machine can not only stir the cut food materials, but also directly process blocky food materials, improving the multifunctionality and use convenience of the equipment, and meeting the needs of users for processing different food materials.

[0014] Further, the number of first ribs and the number of second ribs are both multiple, and the multiple first ribs and the multiple second ribs are circumferentially arranged around the axis of the stirring shaft.

[0015] The multiple ribs are circumferentially arranged around the stirring shaft, allowing the stirring shaft to apply force to the food materials from multiple directions when rotating, thereby avoiding uneven mixing caused by one-way flow of the food materials in the inner container. The multiple first ribs and the multiple second ribs can further enhance the stirring intensity and range, ensuring that the food materials in each area of the inner container are fully stirred. The circumferential arrangement allows the stirring force to be more evenly distributed, reducing the splashing of food materials or the vibration of the equipment caused by excessive local force, thereby improving the stability of the stirring process. At the same time, the multiple rib structure can also speed up the flow of food materials, shorten the stirring time, and improve the efficiency of making paste, allowing users to enjoy the finished product faster.

[0016] Further, a positioning shaft is provided between the stirring shaft and the worm gear structure, the positioning shaft is circumferentially connected with the stirring shaft, the positioning shaft and the stirring shaft can be axially assembled and detached, the positioning shaft is rotationally connected with the inner container and a sealing ring is provided therebetween.

[0017] The positioning shaft is provided to achieve flexible connection and precise positioning of the stirring shaft and the worm gear structure. The circumferential connection ensures that the positioning shaft can drive the stirring shaft to rotate synchronously, the power transmission is not slippery, and the stirring effect is guaranteed. The axial assembly and detachment design facilitates the disassembly and assembly of the inner container, and the user only needs to lift the inner container upwards to separate it from the positioning shaft, which is convenient to operate. The rotational connection of the positioning shaft and the inner container reduces the friction between the stirring shaft and the inner container when the stirring shaft rotates, thereby reducing wear. The sealing ring can effectively prevent the food materials and soup in the inner container from seeping into the joint gap between the positioning shaft and the inner container, thereby preventing the leakage of soup from damaging the internal components of the equipment, and also facilitating cleaning, thereby improving the hygiene and service life of the equipment.

[0018] Further, one end of the rotating shaft is provided with a rotating speed detection assembly for detecting the rotating speed, and the other end is provided with a fan assembly for heat dissipation or auxiliary airflow.

[0019] The rotating speed detection assembly can monitor the rotating speed of the rotating shaft in real time and feed back the information to the control system, so that the operation panel can accurately adjust the motor speed according to the set parameters, ensuring that the stirring speed is stable within the required range and improving the consistency of paste making. The fan assembly is provided at the other end of the rotating shaft and rotates synchronously when the rotating shaft rotates, which can generate airflow to dissipate heat from the heating components such as the motor structure, thereby reducing the internal temperature of the equipment and avoiding the influence of overheating on the performance and service life of the components. At the same time, the auxiliary airflow can also promote the air circulation inside the equipment, further improving the heat dissipation effect. This design of detecting at one end and dissipating heat at the other end ensures the accurate control of the stirring speed and the stable operation of the equipment, thereby improving the reliability of the product.

[0020] Further, the base has a bottom shell and a support plate body, the operation panel is arranged on the support plate body, the bottom shell is provided with a heat dissipation fin group and a first support rib group, the support plate body is provided with a second support rib group, and the first support rib group is clamped with the second support rib group.

[0021] The bottom shell and the support plate body of the base are designed separately, facilitating the installation and maintenance of internal components. The heat dissipation fin group can increase the contact area between the base and the air, accelerate the dissipation of heat inside the equipment, and improve the overall heat dissipation effect in cooperation with the fan blade assembly, thereby ensuring the stability of the equipment during long-time operation. The first support rib group and the second support rib group are clamped, so that the bottom shell and the support plate body are firmly connected, improving the overall structural strength of the base and effectively supporting the upper structure such as the pot body assembly, thereby preventing deformation of the base. The operation panel is arranged on the support plate body, which is eye-catching and convenient for users to operate, and at the same time provides a stable installation foundation for the operation panel, ensuring that the operation panel is not easy to loosen or damaged during use.

[0022] Further, the pot body assembly has an inner layer pot body and an outer layer pot body, a sandwich layer is formed between the inner layer pot body and the outer layer pot body, the heating assembly is located in the sandwich layer, and a plurality of telescopic positioning members are arranged on the circumference of the inner liner. The inner layer pot body is provided with a plurality of positioning holes corresponding to the plurality of telescopic positioning members, and the telescopic positioning members and the positioning holes enable the inner liner and the pot body assembly to be circumferentially limited.

[0023] The double-layer structure of the pot body assembly forms a sandwich layer, and the heating assembly is placed in the sandwich layer, which can uniformly heat the inner liner on the inner side and avoid direct contact between the heating assembly and the outside, preventing user scalding and improving safety. The sandwich layer also has a certain heat preservation effect, reducing heat loss and improving energy utilization efficiency. The telescopic positioning members on the circumference of the inner liner cooperate with the positioning holes of the inner layer pot body to realize the circumferential limitation of the inner liner and the pot body assembly, preventing the inner liner from rotating synchronously with the stirring shaft during stirring, and ensuring that the stirring protrusions can effectively stir the food materials. The telescopic positioning member design makes the installation and disassembly of the inner liner more convenient, and only needs to rotate the inner liner slightly to complete positioning or separation, thereby improving the user experience.

[0024] The beneficial effects of this utility model are as follows: The structure of this paste maker combines practicality and stability. The control panel allows for intuitive adjustment of heating and stirring parameters. The detachable design of the pot and lid facilitates easy disassembly and cleaning of the inner pot. The heating components are designed to improve thermal efficiency by corresponding to the inner pot. The circular ring and conical protrusions on the stirring shaft, with their arc-shaped transition, form a three-dimensional stirring space. Combined with multiple sets of ribs with different angles and L-shaped serrated blades, it can stir the ingredients in all directions, reducing dead corners and efficiently cutting lumpy ingredients, improving uniformity and fineness. The stirring drive component, through a motor, brake, and worm gear structure, achieves smooth power transmission and safe braking. The positioning shaft design ensures precise transmission of the stirring shaft and is leak-proof and easy to disassemble. The rotation speed detection component at the shaft end ensures stable stirring speed, and the fan blade assembly assists in heat dissipation. The base support ribs are snapped together to enhance structural strength, and the heat dissipation fins improve heat dissipation. The double-layer pot body with interlayer heating is both safe and heat-insulating. The inner pot telescopic positioning component provides circumferential limitation, improving the overall user experience and equipment reliability. Attached Figure Description

DETAILED DESCRIPTION

[0033] In order to further illustrate the technical means and effects adopted by the utility model to achieve the predetermined utility model purposes, the specific embodiments, structures, features and effects according to the utility model will be described in detail as follows in combination with the drawings and preferred embodiments.

[0034] Please refer to Figures 1 to 7 As shown in the drawings, the utility model relates to a paste machine for heating and stirring food materials, which comprises a base 1, an operation panel 2 arranged on the base 1, a pot body assembly 3, a heating assembly 7 and a stirring drive assembly 5, an inner container 6 arranged in the pot body assembly 3 for containing food materials, a stirring shaft 4 rotatably arranged in the inner container 6, and a cover body assembly 8 detachably connected with the pot body assembly 3, wherein the operation panel 2 is electrically connected with the stirring drive assembly 5 and the heating assembly 7, the pot body assembly 3 and the cover body assembly 8 are detachably connected to position the inner container 6 therebetween, the stirring shaft 4 is arranged in the inner container 6 to stir the food materials, and the heating assembly 7 heats the inner container 6 to heat the food materials contained therein.

[0035] In the specific implementation process, the paste machine cooperatively works around the components. First, the base 1 serves as the support base of the whole machine, providing a stable mounting platform for the operation panel 2, the stirring drive assembly 5 and other core components, so as to ensure that the components will not shake or displace during work. Before use, the user needs to put the food materials to be processed into the inner container 6, then accurately place the inner container 6 into the pot body assembly 3, and then detachably connect the pot body assembly 3 and the cover body assembly 8 through the detachable connection structure (such as buckle connection or threaded connection) to buckle them, at this time, the inner container 6 will be firmly positioned between the pot body assembly 3 and the cover body assembly 8, so as to avoid displacement during heating and stirring.

[0036] When the user issues a work command via the control panel 2 on the base 1, the command is quickly transmitted to the corresponding components because the control panel 2 is electrically connected to both the stirring drive component 5 and the heating component 7. Upon receiving the command, the stirring drive component 5 activates its internal motor. The power output from the motor is transmitted to the stirring shaft 4 via a transmission mechanism (such as gear or belt drive), causing the stirring shaft 4 to rotate around its own axis within the inner liner, thus stirring and mixing the ingredients to ensure even heating and a fine texture. Simultaneously, the heating component 7 (usually an electric heating element or an electromagnetic heating plate) also begins operation according to the temperature parameters set on the control panel 2. The heat generated directly acts on the outer wall of the inner liner 6, and then, through thermal conduction within the inner liner 6, the heat is transferred to the ingredients inside, heating and raising the temperature of the ingredients, ultimately completing the heating and stirring process.

[0037] Specifically, the stirring shaft 4 is provided with a first stirring protrusion 9 and a second stirring protrusion 11. The first stirring protrusion 9 is a circular structure, and the second stirring protrusion 11 is a conical structure. The first stirring protrusion 9 to the second stirring protrusion 11 form an arc-shaped structure with a decreasing radius.

[0038] During the rotation of the stirring shaft 4, the first stirring protrusion 9 and the second stirring protrusion 11 work together to achieve efficient stirring of the food. The first stirring protrusion 9 adopts a ring structure, and its large annular contact area can agitate the food in the upper and middle layers of the container over a large area, pushing the food to flow horizontally. The second stirring protrusion 11 is designed as a conical structure, and its radius decreases from the first stirring protrusion 9 to the second stirring protrusion 11 in an arc shape. This structure allows the food to flow smoothly from the first stirring protrusion 9 to the second stirring protrusion 11 along the arc surface when the stirring shaft 4 rotates, preventing the food from accumulating between the stirring protrusions.

[0039] The second stirring protrusion 11, with its conical structure, can reach deep into the bottom area of ​​the inner pot 6 to specifically stir ingredients that tend to settle at the bottom, preventing them from sticking to the bottom for too long and burning. The arc-shaped transition with a reduced radius also reduces the flow resistance of the ingredients, making the stirring process smoother. At the same time, it enhances the tumbling effect of the ingredients, improves the overall mixing uniformity, and ensures that ingredients in different areas are fully mixed.

[0040] Specifically, the stirring shaft 4 is provided with a first rib 12, a second rib 14, and a stirring blade 13, with the stirring blade 13 disposed on the first rib 12; the length extension directions of the two ribs are intersecting the axial direction of the stirring shaft 4. The first rib 12 is disposed on a first stirring protrusion 9, and the second rib is disposed on a second stirring protrusion 11. The slope of the first rib 12 relative to the axis of the stirring shaft 4 is greater than the slope of the second rib 14.

[0041] In practical implementation, the structural design of the first rib 12, the second rib 14, and the stirring blade 13 on the stirring shaft 4 further improves the efficiency and uniformity of food mixing. The stirring blade 13 is located on the first rib 12. When the stirring shaft 4 rotates, the stirring blade 13 moves synchronously with the first rib 12. Its sheet-like structure can laterally cut and push the food in the container, breaking up the clumping of the food and promoting rapid mixing. The length extension direction of the two ribs is intersected with the axial direction of the stirring shaft 4. This non-parallel layout allows the ribs to not only drive the food to flow circumferentially during rotation, but also guide the food to move axially up and down, avoiding the food from circulating and mixing only on the same horizontal plane.

[0042] The first rib 12 is located on the first stirring protrusion 9. Its slope relative to the axis of the stirring shaft 4 is greater than that of the second rib 14 located on the second stirring protrusion 11. The first rib 12 with a larger slope has a stronger axial pushing force on the middle and upper layer of ingredients, which can guide the middle and upper layer of ingredients downward to the middle area of ​​the inner pot 6. The second rib 14 with a smaller slope can gently stir the bottom ingredients and transport the bottom ingredients upward, forming a convection circulation with the ingredients guided by the first rib 12. Combined with the cutting and stirring of the stirring blade 13, the ingredients in the inner pot are fully mixed in all directions without dead corners, which further improves the smoothness and consistency of the paste.

[0043] Specifically, the stirring drive assembly 5 includes a rotating shaft 15 and a motor structure 16, a brake structure 17, and a worm gear structure 18 mounted on the rotating shaft 15. The rotating shaft 15 and the worm gear structure 18 are both rotatably supported on the support plate 28. The motor structure 16 is used to drive the rotating shaft 15 to rotate, the brake structure 17 is used to brake the rotating shaft 15, and the worm gear of the worm gear structure 18 is coaxially connected to the stirring shaft 4.

[0044] When the control panel 2 issues a stirring command, the motor structure 16 starts and outputs power, driving the connected rotating shaft 15 to rotate. The rotating shaft 15 rotates stably under the rotational support of the support plate 28, simultaneously driving the worm gear structure 18 mounted on the rotating shaft 15. The worm gear structure 18 has the function of speed reduction and torque amplification, converting the high-speed, low-torque rotation of the motor structure 16 into low-speed, high-torque rotation. This torque is then transmitted to the stirring shaft 4, which is coaxially connected to the worm gear, ensuring that the stirring shaft 4 obtains a suitable speed and torque for stirring the ingredients. This guarantees the stirring effect while preventing damage to components due to excessive torque.

[0045] The support plate 28 provides stable support for the rotating shaft 15 and the worm gear structure 18, preventing shaking or displacement during operation. When the stirring work is completed or the user needs to pause, the control panel 2 issues a braking command, and the brake structure 17 immediately activates, braking the rotating shaft 15 to quickly stop its rotation. This, in turn, drives the stirring shaft 4 to stop stirring via the worm gear structure 18, ensuring safe and convenient operation. The entire stirring drive assembly 5 achieves precise control of the rotation of the stirring shaft 4 through the coordinated operation of the motor, rotating shaft 15, worm gear, and brake.

[0046] Specifically, the stirring blade 13 has a horizontal blade portion 19 and a vertical blade portion 21. The horizontal blade portion 19 is arc-shaped, and the horizontal blade portion 19 and the vertical blade portion 21 together form an L-shape. The stirring blade 13 has a serrated structure 22 in the width direction.

[0047] The L-shaped structure of the stirring blade 13 consists of a horizontal blade 19 and a vertical blade 21. When the stirring shaft 4 rotates, it can stir the food from different dimensions. The horizontal blade 19 is arc-shaped. When its arc-shaped surface comes into contact with the food during rotation, it can generate a stronger pushing force, pushing the food to flow along the arc-shaped trajectory of the horizontal blade 19, enhancing the circumferential rotation effect of the food. At the same time, the arc-shaped structure can reduce the resistance when the food flows, making the stirring smoother.

[0048] The vertical blade 21 primarily generates axial stirring force on the ingredients, forming a three-dimensional stirring space in conjunction with the horizontal blade 19, preventing the ingredients from rotating only in a single plane. The serrated structure 22 in the width direction of the stirring blade 13 further enhances the stirring performance. When the stirring blade 13 rotates, the serrations can cut and grind the ingredients. For harder ingredients or ingredients that are prone to clumping, the serrations can effectively break them up and disperse them, making the ingredients easier to stir evenly. This combination of L-shaped structure and serrations allows the stirring blade 13 to achieve multi-dimensional stirring, cutting, and dispersion of ingredients within a limited space, significantly improving the stirring efficiency and quality of the paste maker, ensuring that the paste produced is fine and uniform.

[0049] Specifically, there are multiple first ribs 12 and multiple second ribs 14, and the multiple first ribs 12 and multiple second ribs 14 are arranged circumferentially around the axis of the stirring shaft 4.

[0050] Multiple first ribs 12 and second ribs 14 are arranged circumferentially around the stirring shaft 4, forming a ring-shaped stirring structure. When the stirring shaft 4 rotates, the circumferentially arranged ribs apply stirring force to the food from all directions, preventing any dead zones in the stirring process. For the first ribs 12, the ring-shaped distribution ensures that the upper and middle layers of food receive uniform stirring and axial thrust at all circumferential positions, allowing the food to rotate evenly circumferentially while simultaneously circulating vertically. The circumferential arrangement of the multiple second ribs 14 ensures that the food at the bottom of the inner pot 6 is stirred omnidirectionally, preventing uneven rib distribution from causing localized food scorching at the bottom.

[0051] Furthermore, the multiple ribs increase the contact area between the ribs and the ingredients, improving the mixing efficiency per unit time and enabling the ingredients to achieve a uniform mixture in a shorter time. At the same time, the circumferential structure makes the mixing shaft 4 more evenly stressed during rotation, reducing the shaking of the mixing shaft 4 caused by uneven stress on the ribs, and improving the stability and service life of the entire mixing system.

[0052] Specifically, a positioning shaft 23 is provided between the stirring shaft 4 and the worm gear structure 18. The positioning shaft 23 is circumferentially engaged with the stirring shaft 4. The positioning shaft 23 and the stirring shaft 4 can be assembled and disassembled along the axial direction of the stirring shaft 4. The positioning shaft 23 is rotatably connected to the inner liner 6 and a sealing ring 24 is provided between them.

[0053] The positioning shaft 23 plays a crucial role in connecting and positioning the stirring shaft 4 and the worm gear structure 18. The circumferential engagement structure (such as a keyed connection or spline connection) between the positioning shaft 23 and the stirring shaft 4 ensures synchronous rotation in the circumferential direction. When the worm gear structure 18 drives the positioning shaft 23 to rotate, the positioning shaft 23 reliably transmits torque to the stirring shaft 4, causing the stirring shaft 4 to rotate accordingly. The axial assembly and disassembly design of the positioning shaft 23 and the stirring shaft 4 facilitates the disassembly and maintenance of the paste machine. When cleaning the inner tank 6 or replacing the stirring shaft 4 is required, the stirring shaft 4 can be easily removed axially from the positioning shaft 23.

[0054] The positioning shaft 23 is rotatably connected to the inner pot 6, allowing it to rotate stably relative to the inner pot 6 while driving the stirring shaft 4, thus avoiding interference with the inner pot 6. The sealing ring 24 between them serves a sealing function, preventing food juices or moisture in the inner pot 6 from leaking into the paste maker through the connection gap between the positioning shaft 23 and the inner pot 6. This protects the internal electrical components from damage and also prevents leaked juices from causing hygiene hazards. Through these designs of the positioning shaft 23, reliable transmission of the stirring shaft 4, convenient disassembly and assembly, and sealed protection of the inner pot 6 are achieved.

[0055] Specifically, one end of the rotating shaft 15 is provided with a rotation speed detection component 25 for detecting rotation speed, and the other end is provided with a fan blade assembly 26 for heat dissipation or auxiliary airflow.

[0056] A speed detection component 25 is located at one end of the rotating shaft 15. During the operation of the stirring drive component 5, it detects the speed of the rotating shaft 15 in real time. The detected speed signal is transmitted to the control system of the paste maker. The control system compares the actual speed with the target speed set on the operation panel 2. If there is a deviation, it adjusts the output power of the motor structure 16 in time to keep the speed of the rotating shaft 15 within the set range, thereby achieving precise control of the speed of the stirring shaft 4 and ensuring that the mixing effect of the ingredients meets the user's needs. The fan blade assembly 26 at the other end of the rotating shaft 15 rotates along with the rotating shaft 15, generating airflow.

[0057] When the fan blade assembly 26 is used for heat dissipation, the generated airflow can blow towards heat-generating components such as the motor structure 16 and the brake structure 17, carrying away heat, reducing the operating temperature of the components, preventing damage due to overheating, and extending their service life. If used for auxiliary airflow, the airflow can assist in internal air circulation or assist in the food processing process under certain circumstances (such as accelerating the evaporation of moisture from the surface of the food). The speed detection assembly 25 and the fan blade assembly 26 are respectively located at both ends of the rotating shaft 15. Without interfering with each other, they each realize the functions of speed control and heat dissipation / auxiliary airflow, improving the overall performance and reliability of the paste machine.

[0058] Specifically, the base 1 has a bottom shell 27 and a support plate 28. The operation panel 2 is disposed on the support plate 28. The bottom shell 27 is provided with a heat dissipation fin group 29 and a first support rib group 31. The support plate 28 is provided with a second support rib group 32. The first support rib group 31 and the second support rib group 32 are engaged.

[0059] The base shell 27 of the base 1 is securely connected to the support plate 28 through a snap-fit ​​structure of the first support rib group 31 and the second support rib group 32. This snap-fit ​​method facilitates the assembly and disassembly of the base 1, while ensuring the connection strength between the base shell 27 and the support plate 28. This allows the base 1 to stably support the upper structure such as the pot assembly 3 and the stirring drive assembly 5, preventing deformation or loosening of the base 1 during use. The operation panel 2 is mounted on the support plate 28, which provides a stable mounting platform for the operation panel 2, preventing displacement or damage due to vibration of the base 1, and also facilitating user operation.

[0060] The heat dissipation fins 29 on the bottom shell 27 are mainly used to dissipate the heat generated by the internal components of the paste machine during operation. By increasing the contact area with the air, the heat dissipation fins 29 quickly transfer internal heat to the external environment, maintaining the internal components at a suitable temperature. In addition to their connecting function, the first support rib group 31 and the second support rib group 32 also enhance the overall structural strength of the base 1, disperse the pressure transmitted from the upper structure, prevent excessive local stress on the base 1 and damage, and improve the structural stability and service life of the entire paste machine.

[0061] Specifically, the pot body assembly 3 has an inner pot body 33 and an outer pot body 34, with a sandwich layer formed between the inner pot body 33 and the outer pot body 34. The heating component 7 is located in the sandwich layer. The inner pot 6 is provided with a plurality of telescopic positioning members 35 in the circumferential direction. The inner pot body 33 is provided with a plurality of positioning holes 36 corresponding to the plurality of telescopic positioning members 35. The telescopic positioning members 35 and the positioning holes 36 enable the inner pot 6 and the pot body assembly 3 to be circumferentially limited.

[0062] The interlayer formed between the inner pot body 33 and the outer pot body 34 of the pot body assembly 3 provides installation space for the heating component 7. Located within this interlayer, the heating component 7 can heat the inner pot 6 at close range, improving heating efficiency, while also providing insulation from the outside through the outer pot body 34, preventing users from being burned by touching the outside of the pot body assembly 3 during use, thus enhancing safety. Multiple telescopic positioning elements 35 on the circumferential direction of the inner pot 6 cooperate with multiple positioning holes 36 on the inner pot body 33 to achieve circumferential positioning of the inner pot 6 and the pot body assembly 3.

[0063] When the inner pot 6 is placed into the pot assembly 3, the telescopic positioning component 35 contracts under the pressure. After the inner pot 6 is in place, the telescopic positioning component 35 aligns with the positioning hole 36 and extends under its own elasticity, locking into the positioning hole 36, thereby restricting the circumferential rotation of the inner pot 6 relative to the pot assembly 3. This circumferential limiting structure ensures that the inner pot 6 will not rotate with the stirring shaft 4 when the stirring shaft 4 drives the food to stir, ensuring the normal operation of the stirring work. It also avoids damage caused by friction between the inner pot 6 and the pot assembly 3 during the rotation process. The cooperation of multiple telescopic positioning components 35 and positioning holes 36 also makes the positioning of the inner pot 6 more accurate and stable, improving the overall working reliability of the paste maker.

[0064] The working principle of this utility model is as follows: When processing food ingredients using the paste maker, the first step is to place the ingredients and assemble the equipment: After placing the ingredients to be processed into the inner pot 6, the inner pot 6 is placed in the inner pot body 33 of the pot body assembly 3. The circumferential telescopic positioning member 35 of the inner pot 6 contracts under the action of compression. After the inner pot 6 is placed in place, the telescopic positioning member 35 aligns with the positioning hole 36 of the inner pot body 33 and elastically extends and snaps into the hole, realizing the circumferential limitation between the inner pot 6 and the pot body assembly 3. Subsequently, the cover assembly 8 and the pot body assembly 3 are assembled through detachable connection structures such as buckles and threads. During the assembly process, the inner pot 6 is stably clamped between the two to ensure that it will not shift during subsequent stirring and heating. At the same time, the bottom shell 27 of the base 1 and the support plate 28 are connected by the first support rib group 31 and the second support rib group 32, providing stable support for the entire equipment. The operation panel 2 is located on the support plate 28 for convenient user operation.

[0065] After assembly, the user inputs operating commands such as stirring speed, heating temperature, and working time through the operation panel 2. The operation panel 2 transmits electrical signals to the stirring drive assembly 5 and the heating assembly 7 respectively. The heating assembly 7 is located in the interlayer formed by the inner pot body 33 and the outer pot body 34 of the pot body assembly 3. After being powered on, it quickly transfers heat to the inner pot body 33, and then conducts it to the inner pot 6, ultimately heating the food inside the inner pot 6. In the stirring drive assembly 5, the motor structure 16 starts and drives the rotating shaft 15 to rotate. The rotating shaft 15 rotates stably under the support of the support plate 28, and at the same time drives the worm gear structure 18 to rotate. The worm gear structure 18 converts the high-speed, low-torque rotation of the motor into low-speed, high-torque rotation, which is transmitted to the stirring shaft 4 through the positioning shaft 23 (the positioning shaft 23 and the stirring shaft 4 are circumferentially engaged to rotate synchronously, and are rotatably connected to the inner pot 6 and are equipped with a sealing ring 24 to prevent leakage), so that the stirring shaft 4 rotates in the inner pot at an appropriate speed and torque.

[0066] The first stirring protrusion 9 (with the first rib 12 and L-shaped serrated stirring blade 13) and the second stirring protrusion 11 (with the second rib 14) on the stirring shaft 4 work together to perform multi-dimensional stirring of the ingredients, avoiding local overheating and scorching. The speed detection component 25 at one end of the rotating shaft 15 detects the speed in real time and feeds it back to the control system to ensure accurate speed. The fan blade assembly 26 at the other end generates airflow to dissipate heat from the internal components or to provide auxiliary airflow. When the work is completed or needs to be paused, the operation panel 2 sends a braking command, and the brake structure 17 is activated to brake the rotating shaft 15, causing the stirring shaft 4 to stop rotating, thus completing the heating and stirring processing of the ingredients and meeting the needs of making paste-like ingredients.
