Description

A reliable food processing machine Technical Field

[0001] This application relates to the field of food processing machines, and more specifically to a reliable food processing machine. Background Technology

[0002] One type of existing blender or soymilk maker includes a main unit and a cup assembly. The cup assembly includes a grinding cup and a outer shell located below the grinding cup. The motor is located inside the outer shell. In order to provide heat dissipation space for the motor, the outer shell is generally quite tall, making the cup assembly tall overall. The top of the main unit usually has a recessed mounting cavity to accommodate the cup assembly. The main unit is also quite tall. After the cup assembly is installed, the overall size of the machine is relatively large. On the one hand, this increases the raw material cost of the product, and on the other hand, it is inconvenient for users to move and store.

[0003] Based on the aforementioned model, to achieve motor heat dissipation, the cup body shell is equipped with an air inlet and an air outlet that communicate with the outside. After the cup body assembly is installed in the main unit, the air inlet and air outlet are connected to the air duct inside the main unit, thereby achieving heat dissipation during machine operation. Since the air inlet and air outlet are always in the open state, when the cup body assembly is cleaned, cleaning water can easily enter the cup body shell through the air inlet and air outlet, causing damage to the motor structure or affecting the normal connection of subsequent circuits, thus affecting the reliability and lifespan of the machine. Summary of the Invention

[0004] This application provides a reliable food processing machine designed to solve the technical problems in the prior art where the height of the cup assembly and main unit with motor is too large, and water easily enters through the open air inlet and outlet at the bottom of the cup assembly, thereby affecting the performance and lifespan of the internal electrical components of the cup assembly.

[0005] The technical solution adopted in this application is as follows:

[0006] A reliable food processing machine includes a horizontally extending base and a mixing cup assembly mounted on the base. The mixing cup assembly includes a cup body, a pulverizing blade disposed within the cup body, a cup body outer shell fixed to the lower end of the cup body, and a motor disposed within the cup body outer shell for driving the pulverizing blade to rotate. The top of the base has a convex positioning ring that protrudes above the top surface of the base. The bottom of the cup body outer shell has a concave positioning groove. The positioning ring is inserted into the positioning groove. The side wall of the positioning groove has an air inlet and an air outlet. The positioning ring has an air inlet corresponding to the air inlet and an air outlet corresponding to the air outlet. A blocking member is disposed inside the cup body outer shell. The blocking member has a trigger portion protruding from the cup body outer shell. When the mixing cup assembly is mounted on the base, the base triggers the trigger portion to move the blocking member to open the air inlet and the air outlet. When the mixing cup assembly is separated from the base, the blocking member moves to block the air inlet and the air outlet.

[0007] In this technical solution, while meeting the required cup manufacturing capacity, the dimensions of the mixing cup assembly and base are reduced compared to existing products. This effectively lowers the height of the mixing cup assembly and base, resulting in a smaller overall size. This not only saves material costs but also reduces the overall weight for users, making it easier to move and store. Furthermore, the positioning ring and positioning slot interlock to achieve quick and accurate positioning and installation of the mixing cup assembly, ensuring stability during operation and preventing shaking, thus improving safety and reliability. Simultaneously, the space between the positioning ring and positioning slot forms an air duct structure, facilitating the installation of the mixing cup assembly while also promoting further... The overall height of the machine is reduced, achieving a miniaturized design. By incorporating a shielding component, the problem of water ingress during stand-alone operation of the mixing cup assembly, such as when placed on a wet surface or during cleaning, is solved. After the mixing cup assembly is removed from the base, the shielding component seals the air inlet and outlet, achieving a waterproof seal and improving the machine's performance and lifespan. Furthermore, as a movable component, the shielding component can open the air inlet and outlet when the mixing cup assembly is installed in place, ensuring airflow between the base and the mixing cup assembly and meeting the overall heat dissipation requirements. Therefore, it balances waterproofing of the mixing cup assembly and overall heat dissipation, improving the machine's overall performance and enhancing the user experience.

[0008] Optionally, the shielding member includes a mounting portion and a shielding portion extending downward from the mounting portion, the shielding portion moving in a vertical direction to open the air inlet and the air outlet and to block the air inlet and the air outlet.

[0009] In this technical solution, the vertically extending shielding part can fit well with the air inlet and outlet, thereby ensuring the sealing effect of the air inlet and outlet, improving the waterproof performance of the mixing cup assembly. The vertical movement of the shielding part realizes the opening and closing control of the air inlet and outlet, which not only helps to simplify the structure of the shielding part, but also makes it easier for the base to trigger the movement of the shielding part, making the whole machine simple to configure and easy to use.

[0010] Optionally, the air inlet and the air outlet are disposed on the inner ring sidewall of the positioning groove, and the air inlet and the air outlet are disposed on the inner ring sidewall of the positioning ring.

[0011] In this technical solution, by setting the air intake and exhaust structures on the inner ring side wall of the positioning and mounting structure, it is beneficial for external air to enter the outer shell of the cup body more quickly through the air intake and air inlet, thereby cooling the motor in time and ensuring that the motor operates within a suitable temperature range. At the same time, it is beneficial for the hot air carrying heat to be discharged more quickly through the air outlet and air outlet, thereby improving heat dissipation efficiency and preventing the whole machine from overheating.

[0012] Optionally, the top wall of the positioning groove is provided with a clearance hole, the trigger part extends into the positioning groove through the clearance hole and the trigger part can move up and down along the clearance hole, and when the stirring cup assembly is installed, the positioning ring pushes the trigger part to trigger the trigger part.

[0013] In this technical solution, the triggering part is movably set in the positioning groove, so that when the stirring cup assembly is installed, the positioning ring can act as a driving component to push the triggering part, thereby triggering the blocking component to move upward to open the air inlet and outlet. The base does not need to be equipped with an additional driving component to trigger the blocking component, and the blocking component can be triggered synchronously during the insertion of the positioning ring. This not only simplifies the base structure, but also eliminates the need for additional actions, does not increase the amount of user operation, and improves the ease of use.

[0014] Optionally, a reset member is provided inside the outer shell of the cup body. The reset member is located above the trigger part. When the stirring cup assembly is installed on the base, the trigger part compresses the reset member to cause the reset member to undergo elastic deformation. When the stirring cup assembly is separated from the base, the trigger part moves and resets under the elastic action of the reset member.

[0015] In this technical solution, by setting a reset component, it is ensured that the trigger part can quickly move and reset after the external force is removed to seal the air inlet and outlet, thus ensuring the waterproof performance of the stirring cup assembly.

[0016] Optionally, the triggering part is a hollow triggering post, the resetting element is a spring, one end of the spring is fixed inside the outer shell of the cup body, and the other end of the spring extends into the triggering post.

[0017] In this technical solution, a hollow trigger post is used. On the one hand, the outer side of the trigger post can be triggered by the base, and on the other hand, the space inside the trigger post is effectively utilized to accommodate the spring. When the trigger post compresses the spring, it can ensure that the spring moves along the axial direction of the trigger post, which provides a guiding function and can avoid the spring from deforming radially and affecting the compression effect, thus affecting the subsequent spring's rebound effect on the trigger post.

[0018] Optionally, a first guide post is provided inside the outer shell of the cup body above the trigger post, the upper end of the spring is sleeved and fixed on the first guide post, and the trigger post moves up and down along the first guide post.

[0019] In this technical solution, by setting the first guide post, not only is a spring mounting structure provided, but also a guiding function for the movement of the trigger post is provided, which can ensure the stability and reliability of the axial movement of the trigger post and the spring, thereby ensuring the opening and closing control effect of the shielding part on the air inlet and the air outlet.

[0020] Optionally, the mounting part is provided with a through hole, and the outer shell of the cup body is provided with a second guide post corresponding to the through hole, and the blocking member moves up and down along the second guide post through the through hole.

[0021] In this technical solution, by setting a second guide post, the blocking component can be limited to moving only in the vertical direction. This can prevent the blocking component from deflecting during movement, which would cause the air inlet and outlet to not be fully opened or completely blocked, thus affecting the air intake and exhaust effect and the heat dissipation effect of the motor.

[0022] Optionally, the air inlet and the air outlet are located on the same side of the positioning groove and are adjacent to each other. A shielding member is provided, which includes a mounting part and two spaced shielding parts extending downward from one side of the mounting part. The bottom of the mounting part is provided with a triggering part extending downward, and the triggering part is located in the middle of the two shielding parts.

[0023] In this technical solution, by placing the air inlet and outlet adjacent to each other, only one shielding component can be used to act on both the inlet and outlet simultaneously, saving on the number of components. Moreover, the base only needs to trigger one triggering part to ensure that the air inlet and outlet open or close synchronously, avoiding the possibility that one of them will fail to open or close properly, thus affecting the air intake or exhaust and the waterproof performance, and ensuring the reliability of the machine's heat dissipation and waterproofing. The triggering part is located in the middle of the two shielding parts, which ensures that the shielding components are subjected to balanced force, thereby ensuring the movement effect of the two shielding parts. In addition, after the external air enters the cup shell from the air inlet and cools the motor, the airflow can take a longer route before being discharged from the air outlet. While dissipating heat, the airflow path can also be extended to achieve the purpose of noise reduction, thereby reducing the machine's operating noise.

[0024] Optionally, the positioning ring extends in an arc shape, and a notch is provided on one side of the positioning ring. A lower coupler is provided at the notch, and an upper coupler electrically connected to the lower coupler is provided at the bottom of the cup body shell.

[0025] In this technical solution, the positioning ring adopts a non-closed ring structure, which provides space for the arrangement of the lower coupler and can improve the space utilization. Moreover, the positioning ring and the lower coupler can jointly position the stirring cup assembly, which is conducive to improving the positioning and installation effect of the stirring cup assembly and making the whole machine more stable.

[0043] As shown in Figures 1 to 9, this application provides a reliable food processing machine, including a horizontally extending base 10 and a mixing cup assembly 11 mounted on the base 10. The mixing cup assembly 11 includes a cup body 111, a pulverizing blade 112 disposed within the cup body 111, a cup body shell 113 fixed to the lower end of the cup body 111, and a motor 114 disposed within the cup body shell 113 for driving the pulverizing blade 112 to rotate. The top of the base 10 is provided with a convex positioning ring 12 that is higher than the top surface of the base 10, and the bottom of the cup body shell 113 is provided with a concave positioning groove 13. The positioning ring 12 and the positioning groove 13 are inserted into each other for positioning. The side wall of the groove 13 is provided with an air inlet 131 and an air outlet 132. The positioning ring 12 is provided with an air inlet 121 corresponding to the air inlet 131 and an air outlet 122 corresponding to the air outlet 132. The cup body shell 113 is provided with a shielding member 14. The shielding member 14 is provided with a trigger part 141 extending out of the cup body shell 113. When the stirring cup assembly 11 is installed on the base 10, the base 10 triggers the trigger part 141 to move the shielding member 14 to open the air inlet 131 and the air outlet 132. When the stirring cup assembly 11 is separated from the base 10, the shielding member 14 moves to block the air inlet 131 and the air outlet 132.

[0044] The food processing machine of this application, while meeting the production capacity of the cup body 111, has a smaller size for the mixing cup assembly 11 and the base 10 compared to existing products. This effectively reduces the height of the mixing cup assembly 11 and the base 10, resulting in a smaller overall size. This not only helps save material costs but also reduces the overall weight for users, making it easier to move and store. Furthermore, the positioning ring 12 and positioning groove 13 can be interlocked to achieve quick and accurate positioning and installation of the mixing cup assembly 11, ensuring stability during operation and preventing shaking, thus improving safety and reliability. Simultaneously, the space between the positioning ring 12 and the positioning groove 13 forms an air duct structure, which, while meeting the installation requirements of the mixing cup assembly 11, also helps to further reduce... The compact overall height achieves machine miniaturization. By incorporating a shield 14, the problem of water ingress into the bottom of the mixing cup assembly 11 during independent operation, such as when placed alone on a wet surface or during cleaning, can be solved. After the mixing cup assembly 11 is removed from the base 10, the shield 14 seals the air inlet 131 and air outlet 132, achieving a waterproof seal and improving the machine's performance and lifespan. Furthermore, as a movable component, the shield 14 can open the air inlet 131 and air outlet 132 when the mixing cup assembly 11 is installed in place on the base 10, thus ensuring the airflow between the base 10 and the mixing cup assembly 11 and meeting the overall heat dissipation requirements of the machine. Therefore, it balances the waterproofing of the mixing cup assembly 11 and the overall heat dissipation of the machine, improving the overall performance of the machine and enhancing the user experience.

[0045] As shown in Figure 4, compared to existing main units with a cup mounting cavity, the base 10 is thinner. As shown in Figures 2 and 3, the cup shell 113 does not require a large heat dissipation space, thus reducing the height of the mixing cup assembly 11. This makes the entire unit compact, easy to use, and convenient to store. The positioning ring 12 protrudes upward relative to the bottom wall of the base 10. The positioning ring 12 and the positioning groove 13 are inserted and installed, which not only provides space for heat dissipation airflow but also makes the overall structure compact, which helps to reduce the overall height of the unit and makes the operation of the unit more stable.

[0046] The shielding component 14 of this application does not require separate triggering by the user. It can be triggered in conjunction with the installation of the mixing cup assembly 11, so that the air inlet 131 and the air outlet 132 automatically open when the mixing cup assembly 11 is installed in place. This meets the heat dissipation requirements of the entire machine without increasing the amount of user operation. At the same time, when the mixing cup assembly 11 is removed, the air inlet 131 and the air outlet 132 automatically close, which can fundamentally prevent liquid from entering the cup shell 113, thereby extending the service life of the machine.

[0047] In a preferred embodiment of this application, the shielding member 14 includes a mounting portion 142 and a shielding portion 143 extending downward from the mounting portion 142. The shielding portion 143 moves in a vertical direction to open the air inlet 131 and the air outlet 132 and to block the air inlet 131 and the air outlet 132.

[0048] As shown in Figures 6 to 8, in this embodiment, the vertically extending shielding part 143 can fit well with the air inlet 131 and the air outlet 132, thereby ensuring the sealing effect of the air inlet 131 and the air outlet 132 and improving the waterproof performance of the stirring cup assembly 11. The shielding part 143 moves in the vertical direction to realize the opening and closing control of the air inlet 131 and the air outlet 132, which not only helps to simplify the structure of the shielding part 14, but also makes it easier for the base 10 to trigger the movement of the shielding part 14, making the whole machine configuration simple and convenient to use.

[0049] Specifically, when the mixing cup assembly 11 is installed, the base 10 pushes the trigger part 141 upward, thereby triggering the blocking part 14 to move upward, which is in line with the downward placement of the mixing cup assembly 11. No other directional actions are involved, making the operation convenient.

[0050] It is understood that in other embodiments, the shielding part 143 can also control the opening and closing of the air inlet 131 and the air outlet 132 by rotation to improve the flexibility of the movement mode of the shielding member 14.

[0051] In some embodiments, the top wall of the positioning groove 13 is provided with a clearance hole 133, the trigger part 141 extends into the positioning groove 13 through the clearance hole 133 and the trigger part 141 can move up and down along the clearance hole 133. When the stirring cup assembly 11 is installed, the positioning ring 12 pushes the trigger part 141 to trigger the trigger part 141.

[0052] As shown in Figure 7, in this embodiment, the trigger part 141 is movably disposed in the positioning groove 13, so that when the stirring cup assembly 11 is installed, the positioning ring 12 can act as a driving member to push the trigger part 141, thereby triggering the blocking member 14 to move upward to open the air inlet 131 and the air outlet 132. The base 10 does not need to be equipped with an additional driving member to trigger the blocking member 14, and the blocking member 14 can be triggered synchronously during the insertion of the positioning ring 12. This not only simplifies the structure of the base 10, but also does not require additional actions, does not increase the amount of user operation, and improves the convenience of use.

[0053] Preferably, when the stirring cup assembly 11 is installed in place, the trigger part 141 moves upward until the bottom wall of the trigger part 141 is flush with the lower end face of the clearance hole 133 or the bottom wall of the trigger part 141 is slightly higher than the lower end face of the clearance hole 133, so that the trigger part 141 does not completely disengage from the clearance hole 133, so that the trigger part 141 is always restricted by the clearance hole 133, ensuring the reliability of the reciprocating movement of the trigger part 141.

[0054] It is understood that in other embodiments, the trigger part 141 may protrude from the bottom of the cup shell 113 radially inside the positioning groove 13, and the stirring cup assembly 11 may be moved by the structural trigger shield 14 located inside the positioning ring 12 of the base 10 during installation. The base 10 may be provided with a trigger rib for pushing the trigger part 141, or the trigger part 141 may be triggered by the top wall of the base 10 pushing it.

[0055] In some embodiments, a reset member 15 is provided inside the outer shell 113 of the cup body. The reset member 15 is located above the trigger part 141. When the stirring cup assembly 11 is installed on the base 10, the trigger part 141 compresses the reset member 15 to cause the reset member 15 to undergo elastic deformation. When the stirring cup assembly 11 is separated from the base 10, the trigger part 141 moves and resets under the elastic action of the reset member 15.

[0056] In this embodiment, by setting a reset member 15, it is ensured that the trigger part 141 can quickly move and reset after the external force is removed to block the air inlet 131 and the air outlet 132, thus ensuring the waterproof performance of the stirring cup assembly 11.

[0057] Furthermore, the trigger part 141 is a hollow trigger post, and the reset part 15 is a spring. One end of the spring is fixed inside the outer shell 113 of the cup body, and the other end of the spring extends into the trigger post.

[0058] As shown in Figure 7, a hollow trigger post is used. On one hand, the outer side of the trigger post can be triggered by the base 10; on the other hand, the inner space of the trigger post is effectively utilized, accommodating the spring while ensuring the spring moves axially along the trigger post when compressed. This provides guidance and prevents radial deformation of the spring from affecting the compression effect and the subsequent rebound effect of the spring on the trigger post. It can be understood that, in the state shown in Figure 1, the other end of the spring can abut against the inner bottom wall of the trigger post, or the other end of the spring can be higher than the inner bottom wall of the trigger post, as long as the spring receives a suitable amount of compression when the trigger post moves upward.

[0059] Furthermore, a first guide post 16 is provided inside the outer shell 113 of the cup body above the trigger post, and the upper end of the spring is sleeved and fixed on the first guide post 16, and the trigger post moves up and down along the first guide post 16.

[0060] As shown in Figure 7, by setting the first guide post 16, both the spring mounting structure and the guiding function for the movement of the trigger post are provided, which can ensure the stability and reliability of the axial movement of the trigger post and the spring, thereby ensuring the opening and closing control effect of the shielding part 143 on the air inlet 131 and the air outlet 132.

[0061] In a preferred embodiment of this application, the air inlet 131 and the air outlet 132 are disposed on the inner ring sidewall of the positioning groove 13, and the air inlet 121 and the air outlet 122 are disposed on the inner ring sidewall of the positioning ring 12.

[0062] As shown in Figures 2 to 6, in this embodiment, by setting the air intake and exhaust structures on the inner ring sidewall of the positioning and mounting structure, it is beneficial for external air to enter the cup shell 113 more quickly through the air intake 131 and air inlet 121, thereby cooling the motor 114 in a timely manner and ensuring that the motor 114 operates within a suitable temperature range. At the same time, it is beneficial for the hot air carrying heat to be discharged more quickly through the air outlet 132 and air outlet 122, thereby improving heat dissipation efficiency and preventing the whole machine from overheating.

[0063] In a preferred embodiment of this application, the mounting part 142 is provided with a through hole 144, and the outer shell 113 of the cup body is provided with a second guide post 17 corresponding to the through hole 144. The blocking member 14 moves up and down along the second guide post 17 through the through hole 144.

[0064] As shown in Figure 9, in this embodiment, by setting the second guide post 17, the blocking member 14 can be limited to move only in the vertical direction, which can prevent the blocking member 14 from deflecting during the movement, causing the air inlet 131 and the air outlet 132 to not be fully opened or completely blocked, thereby affecting the air intake and exhaust effect and the heat dissipation effect of the motor 114.

[0065] Based on the above embodiments, as shown in Figure 8, the stirring cup assembly 11 includes a cup body 111, a motor 114, a cup base 115, and a cup body shell 113. The cup base 115 is a through-hole annular cover structure. The bottom wall of the cup base 115 is provided with a first guide post 16 and a second guide post 17, which can provide guidance for the movement of the shielding member 14. The motor 114 has a motor air inlet and a motor air outlet, so that external air enters from the base 10 and flows into the cup body shell 113 through the air inlet 121 and the air inlet 131, then flows into the motor air inlet, carries away the heat of the motor 114, and flows out from the motor air outlet, and then is discharged from the base 10 through the air outlet 132 and the air outlet 122, thereby realizing the heat dissipation of the motor 114.

[0066] In a preferred embodiment of this application, the air inlet 131 and the air outlet 132 are located on the same side of the positioning groove 13 and are adjacent to each other. A shielding member 14 is provided, which includes a mounting part 142 and two spaced shielding parts 143 extending downward from one side of the mounting part 142. A triggering part 141 extending downward is provided at the bottom of the mounting part 142, and the triggering part 141 is located in the middle of the two shielding parts 143.

[0067] As shown in Figures 6 and 8, in this embodiment, by arranging the air inlet 131 and the air outlet 132 adjacent to each other, only one shielding member 14 can be used to act on both the air inlet 131 and the air outlet 132 simultaneously, saving on the number of structures. Moreover, the base 10 only needs to trigger one triggering part 141 to ensure that the air inlet 131 and the air outlet 132 open or close synchronously, which can avoid the situation where one of them fails to open or close properly, affecting the air intake or exhaust and the waterproof performance, thus ensuring the reliability of the machine's heat dissipation and waterproofing. The triggering part 141 is located in the middle of the two shielding parts 143, which can ensure that the shielding member 14 is subjected to balanced force, thereby ensuring the movement effect of the two shielding parts 143. In addition, after the external air enters the cup shell 113 from the air inlet 131 and cools the motor 114, the airflow can take a longer route before being discharged from the air outlet 132. While dissipating heat, the airflow path can be extended to achieve the purpose of noise reduction, thereby reducing the machine's operating noise.

[0068] Based on the above embodiments, as a preferred embodiment of this application, the positioning ring 12 extends in an arc shape, and a notch is provided on one side of the positioning ring 12. A lower coupler 18 is provided at the notch, and an upper coupler 19 electrically connected to the lower coupler 18 is provided at the bottom of the cup body shell 113.

[0069] As shown in Figures 4 and 5, in this embodiment, the positioning ring 12 adopts a non-closed ring structure, which provides space for the arrangement of the lower coupler 18, thereby improving space utilization. Moreover, the positioning ring 12 and the lower coupler 18 can jointly position the stirring cup assembly 11, which is beneficial to improving the positioning and installation effect of the stirring cup assembly 11 and making the whole machine run more stably.
