Description

Technical Field

[0001] This utility model belongs to the field of kitchen appliance technology, specifically relating to a food processing machine. Background Technology

[0002] In existing food processing machines, it is generally necessary to allow for flexible disassembly of the mixing cup relative to the machine base. Simultaneously, the machine base needs to be equipped with a corresponding radial limiting structure to ensure radial restraint and assembly stability of the mixing cup, thus achieving stable operation. Traditional food processing machines often use a horizontally placed heating plate at the bottom of the cup. Although the inner wall of the cup is usually equipped with baffles to enhance material mixing, a mixing blind zone inevitably forms near the core area of ​​the cutter shaft. This results in insufficient mixing and poor uniformity of the material in this area, affecting processing quality. Therefore, some improvement solutions propose setting the heating plate and cutter shaft in an inclined position to eliminate the mixing blind zone.

[0003] However, in traditional food processors, the mixing cup and the base are only radially limited by a C-shaped limiting ring at the top of the base. For example, patent CN222303752U discloses a food processor that reduces resonance. The upper part of the base has a circumferentially extending limiting ring on the radially outer side of the lower connector, and the bottom of the mixing cup has a circumferentially extending limiting groove on the radially outer side of the upper connector. The limiting groove and the limiting ring cooperate to limit and position the upper and lower connectors vertically and vertically. A circumferential limiting structure is provided between the bottom of the mixing cup and the upper part of the base to restrict the circumferential rotation of the mixing cup relative to the base. Specifically, the inner wall of the limiting ring has a radial recess, and limiting ribs are provided on both sides of the radial recess. The limiting boss protrudes radially and inserts into the radial recess to further limit the offset movement of the cup relative to the base. To improve the pulverizing effect of the food processor, the heating plate is tilted. This tilted blade causes the center of gravity of the mixing cup to shift towards the lower side of the blade, making the mixing cup prone to tipping over. During the pulverizing process, the uneven distribution of the liquid flow agitated by the blades within the cup, along with the high-speed rotating pulverized liquid flow, impacts and vibrates the corresponding lower area of ​​the cup, causing significant wobbling and further increasing the likelihood of tipping. Therefore, if the aforementioned radial limiting method is continued between the mixing cup and the machine base, the limiting becomes unreliable, leading to cup tipping, difficulty in ensuring installation accuracy, decreased operational stability, and increased transmission noise. Utility Model Content

[0004] This utility model provides a food processing machine with a stirring cup structure based on the inclined arrangement of the heating plate to reduce the blind zone of stirring. It solves the technical problem that the traditional limiting method between the stirring cup and the main unit will cause the center of gravity of the stirring cup to shift, resulting in the risk of tipping over and poor installation stability of the stirring cup.

[0005] The technical solution adopted in this utility model is as follows: This utility model provides a food processing machine, including a base and a mixing cup assembly detachably mounted on the base. The mixing cup assembly includes a cup body, a blade disc disposed at the bottom of the cup body, and a pulverizing blade disposed within the cup body. The base contains a motor for driving the pulverizing blade to rotate. The bottom of the cup body has an upper coupling connected to the pulverizing blade. The upper part of the base has a lower coupling connected to the motor. The upper part of the base has a C-shaped limiting ring on the radially outer side of the lower coupling. The bottom of the cup body has a limiting groove that cooperates with the limiting ring. The bottom wall of the blade disc slopes downward toward the opening side of the limiting ring. The lower coupling is inclined. The limiting ring has two first limiting grooves symmetrical about the central axis of the opening. The bottom of the cup body has a first limiting rib that cooperates with the first limiting grooves. The two first limiting grooves form a triangular support surface by connecting the center point of the bottom edge of the groove sidewall near the opening side with the center point of the top surface of the lower coupling. The support surface slopes upward from the opening side toward the opposite side of the opening.

[0006] The food processing machine provided by this utility model, under the premise that the bottom wall of the cutter disc is tilted downwards towards the opening of the limiting ring, will cause the center of gravity of the mixing cup to shift towards the opening of the limiting ring during operation. Additionally, the high-speed rotating pulverized liquid flow will impact the corresponding lower area of ​​the cup body, resulting in significant shaking of the mixing cup assembly and a downward tilting force towards the opening. This makes the mixing cup assembly prone to tipping over towards the opening. To address this, two first limiting grooves symmetrical about the central axis of the opening are provided on the limiting ring, and first limiting ribs that mate with the first limiting grooves are provided at the bottom of the cup body. Simultaneously, the coupling is tilted, and the two first limiting grooves are positioned close to... The center point of the bottom edge of the groove sidewall on the open side and the center point of the top surface of the lower coupling form a stable triangular support surface. The support surface slopes upward from the open side toward the opposite side of the opening to provide an upward support force to the stirring cup assembly toward the opposite side of the opening. This effectively counteracts the downward force on the stirring cup assembly toward the open side, thereby reducing the downward offset of the stirring cup assembly's center of gravity and the radial offset, preventing the stirring cup assembly from tipping over. Furthermore, the stirring cup assembly is more stably installed and has higher assembly precision, thus ensuring the alignment effect of the upper and lower couplings and reducing transmission noise.

[0007] In a preferred embodiment, the support surface is parallel to the bottom wall of the cutter head.

[0008] Because the supporting surface is parallel to the bottom wall of the blade disc, the upward tilting force provided by the supporting surface to the mixing cup assembly towards the opposite side of the opening and the downward tilting force on the mixing cup assembly towards the opening can be aligned on the same line. This maximizes the utilization of the upward tilting force provided by the supporting surface to the mixing cup assembly towards the opposite side of the opening, more effectively counteracts the downward tilting force on the mixing cup assembly towards the opening, significantly improves the support stability of the supporting surface to the mixing cup assembly, further avoids the risk of the mixing cup assembly tipping over, improves the working stability of the mixing cup assembly, and reduces transmission noise.

[0009] In a preferred embodiment, the bottom wall of the first limiting groove slopes upward from the side of the opening toward the side opposite to the opening.

[0010] The first limiting groove, in conjunction with the first limiting rib, provides upward support to the mixing cup assembly via the bottom wall of the first limiting groove. Furthermore, the bottom wall of the first limiting groove slopes upwards from the side of the opening towards the opposite side, thus providing vertical or near-vertical support to the mixing cup assembly, resulting in stable installation and higher assembly precision.

[0011] In a preferred embodiment, the bottom wall of the first limiting groove is parallel to the top surface of the lower coupling.

[0012] The bottom wall of the first limiting groove is parallel to the top surface of the lower coupling, so that the bottom wall of the first limiting groove provides a support force perpendicular to the cutter disc for the stirring cup assembly. Moreover, the support force is along the axial direction of the upper and lower couplings, thereby enhancing the alignment effect of the upper and lower couplings, resulting in low transmission noise and stable transmission.

[0013] In a preferred embodiment, the first limiting groove has a first slot located on the top surface of the limiting ring and a second slot located on the inner circumferential surface of the limiting ring, and the first limiting groove is constricted towards the second slot in the radial direction.

[0014] By setting the first limiting groove to contract towards the second groove opening in the radial direction, the first limiting rib can be constrained and securely limited within the first limiting groove by the contracting structure, preventing the first limiting rib from coming out of the first limiting groove, thereby preventing the mixing cup assembly from shifting relative to the base. The installation position of the mixing cup assembly is accurate and stable, and the limiting is reliable.

[0015] More preferably, the inner circumferential surface of the limiting ring is provided with reinforcing ribs that extend vertically along the edge of the second groove.

[0016] By reinforcing ribs to enhance the structural strength of the area surrounding the second groove, the deformation of the limiting ring caused by the force of the first limiting rib or external stress is reduced, thus achieving a continuous and effective limiting effect on the stirring cup assembly.

[0017] In a preferred embodiment, the limiting ring is further provided with a second limiting groove located on the opposite side of the opening, and the bottom of the cup body is provided with a second limiting rib that matches the second limiting groove. The two first limiting grooves are connected at the center point of the bottom edge of the groove sidewall near the opening and the center point of the bottom wall of the second limiting groove to form a transmission area, and the lower coupling is located in the transmission area.

[0018] By setting a second limiting groove on the opposite side of the opening of the limiting ring, and having the second limiting rib at the bottom of the cup body cooperate with it, the center point of the bottom edge of the side wall of the two first limiting grooves near the opening is connected with the center point of the bottom wall of the second limiting groove to form a transmission zone. The lower coupling is located in this transmission zone. With the double cooperation of the first limiting groove and the first limiting rib, and the second limiting groove and the second limiting rib, the relative installation of the cup body and the limiting ring can be accurately positioned, and multiple radial limiting points can be provided. This improves the installation stability of the stirring cup assembly, accurately positions the lower coupling and the upper coupling, ensures reliable power transmission, reduces transmission deviation caused by installation offset or running vibration, and thus improves transmission stability and assembly reliability.

[0019] More preferably, an upwardly protruding support platform is provided in the second limiting groove.

[0020] By setting up a support platform, a thickened section is formed on the bottom wall of the second limiting groove, thereby strengthening the groove opening structure of the second limiting groove, reducing the deformation of the limiting ring caused by the force of the second limiting rib or external stress, and achieving a continuous and effective limiting effect on the stirring cup assembly.

[0021] In a preferred embodiment, the top of the base is further provided with an arc-shaped rib extending along the outer circumferential surface of the limiting ring, the top surface of the arc-shaped rib being an inclined surface parallel to the bottom wall of the cutter disc, and the bottom of the cup body being axially supported on the inclined surface.

[0022] By incorporating the aforementioned arc-shaped ribs, the bottom of the mixing cup assembly preferentially contacts the inclined surface of the arc-shaped ribs during assembly, forming an axial positioning. The parallel relationship between the inclined surface of the arc-shaped ribs and the bottom wall of the cutter head provides a guiding and positioning effect, guiding the precise insertion between the inclined lower and upper couplings, thus achieving accurate installation of the mixing cup assembly. Simultaneously, the arc-shaped ribs extend along the outer circumference of the limiting ring. The arc-shaped ribs and the limiting ring respectively provide axial and radial limiting effects for the mixing cup assembly. Furthermore, the arc-shaped ribs strengthen the structural strength of the limiting ring, ensuring reliable positioning between the mixing cup assembly and the base.

[0023] In a preferred embodiment, the top surface of the limiting ring is inclined and parallel to the bottom wall of the cutter head, and the bottom of the cup body is axially supported by the top surface of the limiting ring.

[0024] By tilting the top surface of the limiting ring to be parallel to the bottom wall of the cutter disc, the installation of the mixing cup is also guided and positioned, guiding the precise insertion between the tilted lower coupling and the upper coupling, thus achieving precise installation of the mixing cup assembly.

[0032] like Figure 1 As shown, in one embodiment, this utility model provides a food processing machine, including a base 10 and a mixing cup assembly 40 detachably mounted on the base 10. Figure 2As shown, the mixing cup assembly 40 includes a cup body 41, a blade disc 42 disposed at the bottom of the cup body 41, and a pulverizing blade 43 disposed within the cup body 41. A motor 20 for driving the pulverizing blade 43 to rotate is provided within the base 10. An upper coupling 44 connected to the pulverizing blade 43 is provided at the bottom of the cup body 41. A lower coupling 21 connected to the motor 20 is provided at the upper part of the base 10. A C-shaped limiting ring 30 is provided radially outward of the lower coupling 21 at the upper part of the base 10. A limiting groove that cooperates with the limiting ring 30 is provided at the bottom of the cup body 41. Figure 2 , 3 As shown, the bottom wall of the cutter head 42 slopes downward toward the opening 301 of the limiting ring 30, and the lower coupling 21 is inclined. Figure 3 , 4 As shown, the limiting ring 30 is provided with two first limiting grooves 31 symmetrical about the central axis M of the opening 301. Figure 5 As shown, the bottom of the cup body 41 is provided with a first limiting rib 45 that mates with the first limiting groove 31. Figure 3 As shown, the two first limiting grooves 31 form a triangular support surface by connecting the center point of the bottom edge of the groove sidewall near the opening 301 with the center point of the top surface of the lower coupling 21, and the support surface slopes upward from the side of the opening 301 toward the opposite side of the opening 301. Figure 3 In the diagram, the triangular surface formed by the dashed lines represents the supporting surface.

[0033] As a preferred option, such as Figure 4 As shown, the upper part of the base 10 is provided with the aforementioned C-shaped limiting ring 30, and the upper part of the base 10 is also covered with a silicone pad 11 that matches the limiting ring 30 and the first limiting groove 31, so as to achieve flexible contact between the base and the mixing cup. Figure 2 , 5 As shown, the mixing cup assembly 40 also includes a cup holder 47 fixed below the cup body 41. The mixing cup assembly 40 is supported above the silicone pad 11 by the cup holder 47. The cup holder 47 is in a limiting engagement with the limiting ring 30, and the first limiting rib 45 is disposed on the cup holder 47.

[0034] The food processing machine provided by this utility model has a problem: because the bottom wall of the blade disc 42 is tilted downwards towards the opening 301 of the limiting ring 30, the center of gravity of the mixing cup assembly 40 will shift towards the opening 301 of the limiting ring 30 during operation. Additionally, the high-speed rotating pulverized liquid flow impacts the corresponding lower area of ​​the cup body 41, causing the mixing assembly 40 to shake significantly and be subjected to a downward force towards the opening 301. This makes the mixing cup assembly 40 prone to tipping towards the opening 301. The solution is to provide two first limiting grooves 31 symmetrical about the central axis M of the opening 301 on the limiting ring 30, and to provide first limiting ribs 45 at the bottom of the cup body 41 that cooperate with the first limiting grooves 31. Simultaneously, the lower coupling 2... 1. The two first limiting grooves 31 form a stable triangular support surface by connecting the center point of the bottom edge of the groove sidewall near the opening 301 with the center point of the top surface of the lower coupling. The support surface is inclined upward from the opening side toward the opposite side of the opening to provide an upward support force to the stirring cup assembly 40 toward the opposite side of the opening 301, so as to effectively counteract the downward force on the stirring cup assembly 40 toward the opening 30, thereby reducing the downward offset of the center of gravity of the stirring cup assembly 40 and the radial offset of the stirring cup assembly 40. The stirring cup assembly 40 is installed more stably and the assembly accuracy is higher, thus ensuring the alignment effect of the upper coupling and the lower coupling and reducing transmission noise.

[0035] In a preferred embodiment, the two first limiting grooves 31 form a triangular support surface parallel to the bottom wall of the cutter head 42 by connecting the center point of the bottom edge of the groove sidewall near the opening 301 with the center point of the top surface of the lower coupling 21.

[0036] Since the supporting surface is parallel to the bottom wall of the blade 42, the upward tilting force provided by the supporting surface to the mixing cup assembly 40 towards the opposite side of the opening 301 and the downward tilting force on the mixing cup assembly 40 towards the opening 301 can be on the same line. This maximizes the utilization of the upward tilting force provided by the supporting surface to the mixing cup assembly 40 towards the opposite side of the opening 301, more effectively counteracts the downward tilting force on the mixing cup assembly 40 towards the opening 301, significantly improves the supporting stability of the supporting surface to the mixing cup assembly 40, further avoids the risk of the mixing cup assembly 40 tipping over, improves the working stability of the mixing cup assembly 40, and reduces transmission noise.

[0037] like Figure 3 As shown, in a preferred embodiment, the bottom wall of the first limiting groove 31 slopes upward from one side of the opening 301 toward the opposite side of the opening 301. More preferably, the bottom wall of the first limiting groove 31 is parallel to the top surface of the lower coupling 21.

[0038] The first limiting groove 31 cooperates with the first limiting rib 45 to provide upward support for the stirring cup assembly 40 using the bottom wall of the first limiting groove 31. The bottom wall of the first limiting groove 31 slopes upward from one side of the opening 301 towards the opposite side, thus providing a vertical or nearly vertical support force to the stirring cup assembly 40 against the cutting disc 42. This results in stable installation of the stirring cup assembly 40 and higher assembly precision.

[0039] The bottom wall of the first limiting groove 31 is parallel to the top surface of the lower coupling 21, so that the bottom wall of the first limiting groove 31 provides a support force perpendicular to the cutter disc 42 to the stirring cup assembly 40, and the support force is along the axial direction of the upper coupling 44 and the lower coupling 21, thereby enhancing the alignment effect of the upper coupling 44 and the lower coupling 21, resulting in low transmission noise and stable transmission.

[0040] like Figure 6 , 7 As shown, in a preferred embodiment, the first limiting groove 31 has a first slot located on the top surface of the limiting ring 30 and a second slot 311 located on the inner circumferential surface of the limiting ring 30, and the first limiting groove 31 is constricted radially toward the second slot. More preferably, the inner circumferential surface of the limiting ring 30 is provided with a reinforcing rib 33 extending vertically along the edge of the second slot.

[0041] By setting the first limiting groove 31 to be constricted radially toward the second groove opening, the first limiting rib 45 can be constrained and securely limited within the first limiting groove 31 by means of the constricted structure, preventing the first limiting rib 45 from coming out of the first limiting groove 31, thereby preventing the stirring cup assembly 40 from shifting relative to the base 10. The installation position of the stirring cup assembly 40 is accurate and stable, and the limiting is reliable.

[0042] The reinforcing rib 33 enhances the structural strength of the area surrounding the second groove, reduces the deformation of the limiting ring 30 caused by the force of the first limiting rib 45 or external stress, and achieves a continuous and effective limiting effect on the stirring cup assembly 40.

[0043] In a preferred embodiment, the limiting ring 30 is further provided with a second limiting groove 32 located on the opposite side of the opening 301, and the bottom of the cup body 41 is provided with a second limiting rib 46 that cooperates with the second limiting groove 32. The two first limiting grooves 31 are connected at the center point of the bottom edge of the groove sidewall near the opening 301 and the center point of the bottom wall of the second limiting groove 32 to form a transmission area, and the lower coupling 21 is located in the transmission area. More preferably, an upwardly protruding support platform is provided in the second limiting groove 32.

[0044] By setting a second limiting groove 32 on the opposite side of the opening 301 of the limiting ring 30, and having the second limiting rib 46 at the bottom of the cup body 41 cooperate with it, the center point of the bottom edge of the side wall of the two first limiting grooves 31 near the opening 301 is connected with the center point of the bottom wall of the second limiting groove 32 to form a transmission area, and the lower coupling 21 is located in this transmission area. With the double cooperation of the first limiting groove 31 and the first limiting rib 45, and the second limiting groove 32 and the second limiting rib 46, the relative installation of the cup body 41 and the limiting ring 30 can be accurately positioned, and multi-point radial limiting can be provided. This improves the installation stability of the stirring cup assembly 40, accurately positions the lower coupling 21 and the upper coupling 44, ensures reliable power transmission, reduces transmission deviation caused by installation offset or running vibration, and thus improves transmission stability and assembly reliability. By setting up a support platform, a thickened section is formed on the bottom wall of the second limiting groove 32, thereby strengthening the groove structure of the second limiting groove 32, reducing the deformation of the limiting ring 30 caused by the force of the second limiting rib 46 or external stress, and achieving a continuous and effective limiting effect on the stirring cup assembly 40.

[0045] like Figure 8 , 9 As shown, in a preferred embodiment, the top of the base 10 is further provided with an arcuate rib 34 extending along the outer peripheral surface of the limiting ring 30. The top surface of the arcuate rib 34 is an inclined surface 341 parallel to the bottom wall of the cutter head 42. The bottom of the cup body 41 is provided with a cup seat 47, and the bottom of the cup seat 47 is provided with an arcuate support rib 48 to axially support the inclined surface 341.

[0046] By setting the aforementioned arc-shaped rib 34, during assembly, the bottom of the stirring cup assembly 40 preferentially contacts the inclined surface 341 of the arc-shaped rib 34, forming a axial positioning. The parallel relationship between the inclined surface 341 of the arc-shaped rib 34 and the bottom wall of the cutter head 42 forms a guiding positioning effect, guiding the precise insertion between the inclined lower coupling 21 and the upper coupling 44, thus achieving precise installation of the stirring cup assembly 40. At the same time, the arc-shaped rib 34 extends along the outer circumferential surface of the limiting ring 30. The arc-shaped rib 34 and the limiting ring 30 respectively provide axial and radial limiting effects for the stirring cup assembly 40. Furthermore, the arc-shaped rib 34 also strengthens the structural strength of the limiting ring 30, achieving reliable limiting between the stirring cup assembly 40 and the base 10.

[0047] Similarly, in a preferred embodiment, the top surface of the limiting ring 30 is inclined and parallel to the bottom wall of the cutter head 42, and the bottom of the cup body 41 is axially supported on the top surface of the limiting ring 30.

[0048] By tilting the top surface of the limiting ring 30 and making it parallel to the bottom wall of the cutter head 42, the installation of the mixing cup is also guided and positioned, guiding the precise insertion between the tilted lower coupling 21 and the upper coupling 44, thereby achieving precise installation of the mixing cup assembly 40.
