Description

Technical Field

[0001] This utility model relates to the field of food processing equipment technology, and in particular to a food processing machine. Background Technology

[0002] Eggs and cream are indispensable ingredients in the pastry-making process. To achieve a soft and creamy texture, the eggs and cream need to be whipped. The mixing bowl inside a food processor can quickly whip the eggs and cream in the mixing bowl through high-speed rotation, making food processors increasingly widely used. To facilitate users in placing and removing the mixing bowl, the upper body of the food processor can rotate relative to the lower body.

[0003] However, when controlling the rotation of the mixing bowl to stir and whip the food, the mixing range of the mixing bowl is limited, which means that the food in the mixing bowl cannot fully contact the mixing bowl, resulting in insufficient whipping and affecting the production effect.

[0097] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0098] This embodiment provides a food processing machine for processing food substances located in a container. For example... Figure 1 and Figure 2As shown, the food processor includes a lower body 1, which includes a lower housing 11. The lower housing 11 includes a horizontal base 111 and a lower support arm assembly 112 extending upward from the horizontal base 111. The horizontal base 111, as a support structure for the entire food processor, is located at the bottom of the food processor to ensure its stability on a table or countertop. A mixing bowl 8 is provided on the horizontal base 111 to hold the food material to be mixed.

[0099] To enable automatic mixing of food materials within the mixing bowl 8, the food processor also includes an upper body 2. The upper body 2 includes an upper housing 21, which comprises a horizontal head 211 positioned above a horizontal base 111 and an upper support arm assembly 212 extending downward from the horizontal head 211. The horizontal head 211 is equipped with an attachment 9 that extends into the mixing bowl 8 and contacts the food materials, allowing the relative movement between the mixing bowl 8 and the attachment 9 to process the food materials. When the mixing bowl 8 rotates, it effectively causes the attachment 9 to perform a circular motion within the mixing bowl 8, enabling the attachment 9 to contact a wider range of food materials within the mixing bowl 8 and improving the mixing effect of the attachment 9 on the food materials inside the mixing bowl 8.

[0100] Furthermore, attachment 9 is rotatably connected to the horizontal head 211, and when attachment 9 rotates, it can also stir the food substances in the mixing bowl 8. In this embodiment, the rotation of attachment 9 and the mixing bowl 8 can greatly improve the stirring effect of the food substances in the mixing bowl 8.

[0101] It is worth noting that in this embodiment, attachment 9 is detachably connected to the horizontal head 211. This means that the type of attachment 9 can be changed according to the type of food substance in the mixing bowl and the processing requirements. For example, attachment 9 can be a dough hook 92, which has a spiral structure and can knead flour and water in the mixing bowl 8. Attachment 9 also includes a baffle rod 93 that works in conjunction with the dough hook 92. The baffle rod 93 is detachably mounted on the horizontal head 211 and is located radially along the mixing bowl 8. The dough hook 92 is positioned between the baffle rod 93 and the side wall of the mixing bowl 8. In other words, the baffle rod 93 creates a flow channel extending circumferentially around the baffle rod 93 inside the mixing bowl 8. Flour and water move around the baffle rod 93 within this flow channel, while the dough hook 92 effectively blocks the movement of the flour and water, thus improving the kneading effect.

[0102] In some embodiments, Attachment 9 may also be a mixing bowl 91, which is capable of whipping eggs and cream in the mixing bowl 8.

[0103] In this embodiment, the lower support arm assembly 112 and the upper support arm assembly 212 form a vertical support arm. The support arm allows the horizontal base 111 and the horizontal head 211 to be spaced apart to provide space for the attachment 9 and the mixing bowl 8. Moreover, the upper support arm assembly 212 is pivotally connected to the lower support arm assembly 112 so that the upper housing 21 has an open position and a working position. When the upper housing 21 is in the open position, the attachment 9 is outside the mixing bowl 8, and the horizontal head 211 does not obstruct the mixing bowl 8, making it easy to remove the mixing bowl 8 to take out or put in food. When the upper housing 21 is in the working position, the attachment 9 extends into the mixing bowl 8, and the horizontal head 211 is above the mixing bowl 8, which can both stir the food in the mixing bowl 8 and facilitate the storage of the food processor when it is not in use, saving space.

[0104] It is worth noting that a decorative cover 13 is provided between the upper body 2 and the lower body 1 of the food processing machine to conceal the internal structure and ensure aesthetics. When the upper body 2 and the lower body 1 are closed, the decorative cover 13 is hidden inside the lower body 1.

[0105] In this embodiment, because the mixing bowl 8 and accessory 9 need to be driven to rotate simultaneously, the food processor requires a high-power drive motor, which increases the size of the drive motor. Therefore, the drive motor can only be installed inside the lower body 1, usually within the lower support arm assembly 112. This results in limited internal space in the lower body 1, with insufficient space to accommodate the decorative cover 13. A smaller decorative cover 13 must be used, causing the internal structure to be exposed when the upper body 2 and lower body 1 are opened, or requiring a reduction in the opening angle between the upper body 2 and lower body 1, which affects the user experience.

[0106] like Figures 3-12 As shown, to solve the above problems, the food processing machine provided in this embodiment includes a lower body 1 with a shielding structure 12 disposed on the lower housing 11. The shielding structure 12 has a receiving groove 121, and a decorative cover 13 is rotatably connected in the receiving groove 121. The decorative cover 13 includes a driven part. When the upper housing 21 is in the working position, part of the decorative cover 13 and part of the shielding structure 12 are located in the upper housing 21. The upper body 2 also includes a drive shaft 22, which is connected to the upper housing 21. During the process of the user rotating the upper housing 21 from the working position to the open position, the drive shaft 22 changes from being spaced apart from the driven part to abutting against the driven part, so as to drive the decorative cover 13 to rotate out of the receiving groove 121 through the driven part, so that the decorative cover 13 blocks the gap between the upper housing 21 and the shielding structure 12. One end of the drive shaft 22 has knurling, and the knurling is fixedly connected to the upper housing 21. The knurling can make the shaft hole fit more firmly and prevent the drive shaft 22 from slipping.

[0107] In this food processing machine, a shielding structure 12 is provided on the lower housing 11, which reduces the size of the gap between the upper housing 21 and the lower housing 11 when the upper housing 21 is in the open position, making it easier for the decorative cover 13 to shield the gap. Furthermore, during the rotation of the upper housing 21 to the open position, when the shielding structure 12 can shield the gap between the upper housing 21 and the lower housing 11, the drive shaft 22 is spaced apart from the driven part, and the decorative cover 13 remains stationary. When the upper housing 21 and the shielding structure 12 no longer overlap, the drive shaft 22 abuts against the driven part, and the decorative cover 13 rotates with the upper housing 21 to shield the gap between the upper housing 21 and the shielding structure 12. Moreover, by providing a receiving space in the upper body 2, when the upper housing 21 is in the working position, part of the decorative cover 13 and part of the shielding structure 12 are located inside the upper housing 21, reducing the space intruded by the decorative cover 13 into the lower housing 11, allowing the decorative cover 13 of the food processing machine to have sufficient size to shield the gap between the upper housing 21 and the lower housing 11.

[0108] This food processing machine can conceal the internal structure without reducing the opening angle of the upper body 2 and the lower body 1, ensuring that the internal structure is not exposed and improving the user experience.

[0109] In this embodiment, the shielding structure 12 is provided with a rotating shaft hole that connects to the decorative cover 13. The decorative cover 13 is rotatably connected to the shielding structure 12 through the rotating shaft hole, which can ensure that the decorative cover 13 maintains an accurate relative position relationship with the shielding structure 12 during rotation, and ensure that the decorative cover 13 can rotate into the receiving groove 121 of the shielding structure 12 or jointly shield the gap between the upper shell 21 and the lower shell 11 with the shielding structure 12.

[0110] like Figure 4 and Figure 5 As shown, the shielding structure 12 and the decorative cover 13 rotate via a pin 122, which passes through a rotating shaft hole. The pin 122 passing through the rotating shaft hole ensures the stability of the decorative cover 13 when rotating relative to the shielding structure 12. Furthermore, the pin 122 has high strength, is easy to replace, improves service life, and reduces maintenance difficulty.

[0111] In order to limit the rotation range of the decorative cover 13, a limiting body 113 is also provided on the lower housing 11, and a positioning protrusion 133 is provided on the decorative cover 13. When the upper housing 21 is in the working position, the positioning protrusion 133 is away from the limiting body 113; when the upper housing 21 is in the open position, the front side of the positioning protrusion 133 abuts against the rear end face of the limiting body 113.

[0112] like Figure 6 , Figures 10-12As shown, the decorative cover 13 has a drive groove 131, which forms a driven part. A drive ring 23 is provided at the end of the drive shaft 22 away from the upper housing 21. The drive shaft 22 passes through the drive groove 131. The process of the upper body 2 rotating from the working position to the open position is divided into a first process and a second process. In the first process, the drive ring 23 is spaced apart from the drive groove 131, and the decorative cover 13 remains stationary. In the second process, the drive ring 23 abuts against at least one side of the drive groove 131, and the decorative cover 13 rotates with the rotation of the upper body 2.

[0113] During the rotation of the upper housing 21 to the open position, the upper housing 21 first undergoes a first process, during which the drive ring 23 is not in contact with the side of the drive groove 131. That is, the decorative cover 13 remains stationary within the receiving groove 121. When the upper housing 21 rotates to the second process, the drive ring 23 abuts against at least one side of the drive groove 131, causing the decorative cover 13 to rotate with the upper housing 21, thereby allowing the decorative cover 13 to rotate out of the drive groove 131 to cover the gap between the upper housing 21 and the lower housing 11. Moreover, since the drive ring 23 is not always in contact with at least one side of the drive groove 131, structurally, the overlap area between the decorative cover 13 and the covering structure 12 is larger, thus further saving space.

[0114] It is worth noting that when the upper shell 21 rotates to the junction of the first process and the second process, the upper shell 21 and the shielding structure 12 have no overlapping range and no gap. As the upper shell 21 continues to rotate, a gap is generated between the upper shell 21 and the shielding structure 12. At this time, the decorative cover 13 begins to rotate with the upper shell 21 to cover the gap between the upper shell 21 and the shielding structure 12 and ensure aesthetics.

[0115] like Figure 3 , Figure 6 and Figure 13 As shown, the decorative cover 13 has baffles 132 at both ends along its own rotation axis. The baffles 132 are located inside the side wall of the upper housing 21. When the upper housing 21 is in the open position, the baffles 132 overlap with the side wall of the upper housing 21 to prevent the decorative cover 13 from shifting. The baffles 132 enable the upper housing 21 to limit the decorative cover 13 even in the open position, preventing the decorative cover 13 from shifting and ensuring that the upper housing 21 will not interfere with the decorative cover 13 when the user rotates the upper housing 21 from the open position to the working position.

[0116] like Figure 12 and Figure 13As shown, the upper housing 21 includes a bottom housing 213, with a decorative cover 13 located below the bottom housing 213. The bottom housing 213 has a receiving hole 2131. When the upper housing 21 is in the working position, a baffle 132 is disposed within the receiving hole 2131. The receiving hole 2131 in the bottom housing 213 can accommodate the baffle 132 of the decorative cover 13 when the upper housing 21 is in the working position, so as to avoid interference between the baffle 132 and the bottom housing 213, which would prevent the upper housing 21 from rotating to the working position.

[0117] like Figures 14-16 As shown, the food processing machine also includes a locking component 3, which includes a fixed base 31 and a locking shaft 32. The fixed base 31 is connected to the upper housing 21, and the locking shaft 32 is slidably disposed on the fixed base 31. The lower body 1 also includes a locking hook 14 connected to the lower housing 11. When the upper housing 21 is in the working position, the locking shaft 32 is engaged and fixed with the locking hook 14.

[0118] The locking shaft 32 of the locking assembly 3 can slide relative to the fixed base 31. When the upper housing 21 is in the working position, the locking shaft 32 is locked by sliding and engaging with the locking hook 14, thereby locking the upper housing 21 in the working position and ensuring the stability of the upper housing 21 when stirring the food in the mixing bowl 8.

[0119] Furthermore, the locking assembly 3 also includes a first elastic member 33, the two ends of which abut against the fixed base 31 and the locking shaft 32 respectively. The first elastic member 33 is configured to elastically abut the locking shaft 32 against the locking hook 14. The first elastic member 33 can provide a locking force to the locking shaft 32, ensuring that the locking shaft 32 always abuts against the locking hook 14, and preventing the locking shaft 32 from disengaging from the locking hook 14 during operation, which would cause the upper housing 21 to unlock and cause a safety accident.

[0120] like Figure 13 and Figure 14 As shown, the food processing machine also includes an unlocking assembly 4, which includes an unlocking slider 41 and an unlocking member 42. The unlocking member 42 is rotatably disposed within the upper housing 21. The first end of the unlocking member 42 slides against the locking shaft 32. The unlocking slider 41 is slidably disposed within the upper housing 21 and abuts against the second end of the unlocking member 42. The unlocking slider 41 can drive the unlocking member 42 to rotate, thereby disengaging the locking shaft 32 from the locking hook 14.

[0121] The user can unlock the upper housing 21 by rotating the unlocking slider 42, which in turn pushes the locking shaft 32, causing the locking shaft 32 to compress the first elastic element 33 and disengage from the locking hook 14. This unlocks the upper housing 21 from the lower housing 11, allowing the user to rotate the upper housing 21 to the open position for easy access to the mixing bowl 8. It is worth noting that the user needs to continuously press the unlocking slider 41 until they feel the locking shaft 32 disengage from the locking hook 14.

[0122] Furthermore, the unlocking slider 41 includes a trigger post 412 and a guide post 411. Both the trigger post 412 and the guide post 411 pass through the upper housing 21, and the guide post 411 is guided and engaged with the upper housing 21. The trigger post 412 slides against the second end of the unlocking member 42, and the end of the guide post 411 is threaded with a limit screw. The screw cap of the limit screw can abut against the upper housing 21 to limit the unlocking slider 41 and prevent the unlocking slider 41 from detaching from the upper housing 21.

[0123] like Figure 15 and Figure 16 As shown, a protective sleeve 43 is fitted onto the first end of the unlocking component 42, and the protective sleeve 43 slides against the locking shaft 32. To ensure the strength of the unlocking component 42, it is made of metal. If the unlocking component 42 directly slides against the locking shaft 32, it will be prone to wear and affect its service life, and will also generate noise. The protective sleeve 43 is made of abrasion-resistant plastic. By using the protective sleeve 43 to slide against the locking shaft 32, the relative movement between the unlocking component 42 and the locking shaft 32 can be smoother and will not generate noise.

[0124] In this embodiment, when it is necessary to unlock the locking component 3, the unlocking slider 41 needs to be moved upward. At this time, the unlocking component 42 rotates, and the first end of the unlocking component 42 can move the locking shaft 32, so that the locking shaft 32 is disengaged from the locking hook 14.

[0125] Generally, the sliding direction of the locking shaft 32 is horizontal or approximately horizontal, while the movement direction of the first end of the unlocking member 42 is approximately vertical when it rotates. In order for the unlocking member 42 to drive the locking shaft 32 to move a sufficient distance to ensure that the locking shaft 32 can disengage from the locking hook 14, the sleeve 43 has a driving inclined surface 421. When the first end of the unlocking member 42 moves along the unlocking direction, the driving inclined surface 421 drives the locking shaft 32 to disengage from the locking hook 14.

[0126] Due to the presence of the driving inclined surface 421, when the first end moves in a generally vertical direction, it can apply a driving force along the moving direction of the locking shaft 32, thereby pushing the locking shaft 32 to move. Specifically, in this embodiment, taking the upper housing 21 in the working position as an example, the driving inclined surface 421 is inclined in a direction away from the unlocking direction of the locking shaft 32 in the downward direction. Therefore, when the unlocking slider 41 is pressed, the first end of the unlocking member 42 moves downward, and the locking shaft 32 slides along the driving inclined surface 421 and disengages from the locking hook 14.

[0127] It is worth noting that the sheath 43 and the unlocking component 42 are made of different materials. The unlocking component 42 has a higher hardness than the sheath 43 to ensure that the sheath 43 can push the locking shaft 32 with the support of the unlocking component 42. Furthermore, the sheath 43 can reduce wear between itself and the locking shaft 32, improve lubrication, and reduce noise during unlocking. Specifically, the unlocking component 42 can be made of materials such as metal or plastic, while the sheath 43 is made of materials such as rubber or polyurethane.

[0128] like Figure 14 and Figure 17 As shown, the unlocking component 42 includes a frame structure, and the unlocking assembly 4 includes two unlocking sliders 41, which are disposed on opposite sides of the upper housing 21. Both unlocking sliders 41 abut against the frame structure. The arrangement of the two unlocking components 42 allows the user to unlock the upper housing 21 with either one hand or both hands, and the force applied when unlocking the upper housing 21 with both hands is more symmetrical, resulting in smoother rotation of the unlocking component 42. The frame structure not only allows the unlocking component 42 to avoid other structures inside the upper housing 21, but also increases the strength of the unlocking component 42, making it less prone to deformation and ensuring that a single unlocking slider 41 can drive the unlocking component 42 to rotate and achieve the unlocking function.

[0129] like Figure 14 and Figure 17 As shown, the unlocking component 42 is equipped with a rotating shaft 422, which rotatably connects the unlocking component 42 to the upper housing 21. The first end and the second end are located on opposite sides of the rotating shaft 422, and the movement direction of the second end is opposite to that of the first end. In other words, the unlocking component 42 acts as a lever. When the user presses the unlocking slider 41 in one direction, the movement direction of the second end of the unlocking component 42 is the same as that of the unlocking slider 41, while the movement direction of the first end of the unlocking component 42 is opposite to that of the unlocking slider 41.

[0130] In this embodiment, the distance L between the trigger post 412 and the rotating shaft 422 is 30mm to 50mm. This distance is the lever arm for the unlocking slider 41 to drive the unlocking component 42 to rotate. It should not be too large or too small. If it is too small, it will be difficult for the user to press the unlocking slider 41. If it is too large, the unlocking stroke of the unlocking slider 41 will be too long, making it inconvenient to use. Specifically, the distance between the trigger post 412 and the rotating shaft 422 can be 30mm, 32mm, 34mm, 36mm, 38mm, 40mm, 42mm, 44mm, 46mm, 48mm, or 50mm.

[0131] When the user rotates the upper housing 21 to the open position, it may be necessary to add or remove food substances to the mixing bowl 8, or to clean the mixing bowl 8. At this time, it is necessary to ensure the stability of the upper housing 21. Figure 3 , Figure 4 , Figure 9 and Figure 16 As shown, in order to achieve the above objective, in this embodiment, the lower body 1 also includes a limiting member 17, which is connected to the lower housing 11. The limiting member 17 has a limiting groove 171. When the upper housing 21 is in the open position, the upper body 2 rotates around the pivot, and the locking shaft 32 is engaged in the limiting groove 171.

[0132] In this embodiment, the upper housing 21 requires a process to rotate from the working position to the open position and from the open position to the working position.

[0133] When switching from the working position to the open position, the unlocking slider 41 needs to be pressed first, so that the unlocking member 42 rotates around the rotating axis 422. The locking shaft 32 slides under the drive of the unlocking member 42 and disengages from the locking hook 14. At this time, the unlocking slider 41 can be released, and the upper housing 21 will rotate around the pivot to the open position. During the rotation of the upper housing 21, the locking shaft 32 returns to the initial state under the pressure release of the first elastic member 33. As the upper body 2 rotates around the pivot, the locking shaft 32 approaches and gets into the limiting groove 171. At this time, it is in the open position, and the locking shaft 32 can be limited by the limiting groove 171 to fix the upper housing 21 in the open position.

[0134] When switching from the open position to the working position, the unlocking slider 41 needs to be pressed first, so that the unlocking member 42 rotates around the rotating axis 422. The locking shaft 32 slides under the drive of the unlocking member 42 and disengages from the limiting groove 171 on the limiting member 17. At this time, the unlocking slider 41 can be released, and the upper housing 21 will rotate around the pivot to the open position. During the rotation of the upper housing 21, the locking shaft 32 returns to the initial state under the pressure release of the first elastic member 33. As the upper body 2 rotates around the pivot, the locking shaft 32 approaches and engages with the locking hook 14. At this time, it is in the working position, and the locking shaft 32 can be limited by the locking hook 14 to fix the upper housing 21 in the working position.

[0135] In summary, when the upper housing 21 is in the open position or the working position, the first elastic element 33 is in the extended state. When the locking shaft 32 is driven by the sleeve 43 on the unlocking member 42, the first elastic element 33 is in the compressed state, so that the locking shaft 32 is disengaged from the limiting groove 171 or the locking hook 14.

[0136] The limiting member 17 is fixed to the lower housing 11. The limiting groove 171 of the limiting member 17 can limit the upper housing 21 through the locking shaft 32, so that the upper housing 21 is stably stopped in the open position. It is worth noting that after the locking shaft 32 is disengaged from the locking hook 14, it is not necessary to keep pressing the button, but the upper housing 21 still needs to be lifted by hand until the locking shaft 32 enters the limiting groove 171 of the limiting member 17. If you want to move the locking shaft 32 out of the limiting groove 171 to rotate the upper housing 21 to the working position, you can still do so by pressing the unlocking slider 41.

[0137] like Figure 10 As shown, the food processor also includes a second elastic element 19, which is configured to drive the upper housing 21 from the working position to the open position and remain between the working position and the open position. That is, when the unlocking component 4 unlocks the locking component 3, the upper housing 21 will rotate and open under the drive of the second elastic element 19, ensuring that the locking shaft 32 will not re-engage with the locking hook 14 after the user releases the locking slider. Moreover, since the second elastic element 19 only keeps the upper housing 21 between the working position and the open position, it can prevent the locking shaft 32 from colliding with the limiting component 17, thus protecting the service life of the food processor. Finally, the user needs to manually rotate the upper housing 21 to the open position to lock the upper housing 21 through the limiting component 17.

[0138] like Figure 3 As shown, the lower housing 11 is provided with a buffer pad 18. When the upper housing 21 is in the open position, the upper housing 21 and the lower housing 11 press against the buffer pad 18. Generally, when the upper housing 21 is in the open position, the redundancy between the upper housing 21 and the lower housing 11 is relatively small. If the user rotates the upper housing 21 at a fast speed, it is easy for the upper housing 21 and the lower housing 11 to collide. The buffer pad 18 can elastically abut against the upper housing 21 when the upper housing 21 approaches the open position, thereby buffering the upper housing 21 and effectively avoiding damage and noise caused by the collision between the upper housing 21 and the lower housing 11.

[0139] For safety reasons, the food processor cannot be started when the upper housing 21 is not in the working position. Figure 17 and Figure 18As shown, to achieve the above objective, a sensing component 6 is provided inside the upper housing 21. The sensing component 6 includes a mounting base 61, a sliding base 62, and a third elastic element 63. The mounting base 61 is fixedly connected to the bottom housing 213. The sliding base 62 is slidably disposed on the mounting base 61. The sliding base 62 is connected to a detection post 64 that penetrates the bottom housing 213. A sensing element 65 is provided on the sliding base 62. The two ends of the third elastic element 63 abut against the mounting base 61 and the sliding base 62 respectively to drive the connecting post to extend out of the bottom housing 213.

[0140] When the upper housing 21 is in the working position, the lower housing 11 presses against the detection column 64 to drive the sliding seat 62 to slide. At this time, the distance between the sensing end of the sensing element 65 and the bottom housing 213 increases. When the upper housing 21 is not in the working position, the elastic element drives the detection column 64 to extend out of the bottom housing 213. At this time, the distance between the sensing end of the sensing element 65 and the bottom housing 213 is minimized. With the above structure, the food processing machine can determine the position of the upper housing 21.

[0141] like Figure 8 and Figure 19 As shown, in order to drive the mixing bowl 8 and attachment 9 to rotate, the food processor also includes a drive assembly 5. The drive assembly 5 includes a drive element 51 and a transmission system. The transmission system is installed in the lower body 1 and / or the upper body 2, and is operatively connected to the drive element 51 and associated with the mixing bowl 8 to rotate the mixing bowl 8. The drive element 51 can drive the mixing bowl 8 to rotate via the transmission system, ensuring that the mixing bowl 8 mixes the food substances. In this embodiment, the transmission system is also connected to attachment 9 to improve the mixing effect on the food substances in the mixing bowl 8.

[0142] Specifically, the transmission system includes an upper transmission system and a lower transmission system. The upper transmission system is connected to the attachment 9, and the lower transmission system is connected to the mixing bowl 8. The upper and lower transmission systems move synchronously and are both connected to the drive component 51. The upper and lower transmission systems can transmit the power of the drive component 51 to the attachment 9 and the mixing bowl 8 respectively, and the upper and lower transmission systems can make the attachment 9 and the mixing bowl 8 move synchronously to ensure the mixing effect.

[0143] In this embodiment, the transmission system also includes a universal joint assembly, which drivesly connects the upper transmission system and the lower transmission system. Since the upper housing 21 and the lower housing 11 of the food processing machine can rotate relative to each other, the direction of power transmission between the upper and lower transmission systems will change. Therefore, a universal joint assembly is needed to prevent the upper and lower transmission systems from jamming.

[0144] Specifically, the lower housing 11 is rotatably provided with a lower connecting seat 15 and a lower universal joint 16. The lower connecting seat 15 is detachably connected to the mixing bowl 8, and the lower connecting seat 15 is drivenly connected to the lower universal joint 16. The upper housing 21 is rotatably provided with an upper connecting seat 24 and an upper universal joint 25. The upper connecting seat 24 is detachably connected to the accessory 9, and the upper connecting seat 24 is drivenly connected to the upper universal joint 25. One end of the upper universal joint 25 is sleeved on one end of the lower universal joint 16 to form a telescopic rod 52.

[0145] When the upper housing 21 rotates relative to the lower housing 11, the telescopic rod 52 will also extend and retract accordingly. The upper universal joint 25 and the lower universal joint 16 at both ends of the telescopic rod 52 will rotate relative to each other, and the length of the telescopic rod 52 will change to adapt to the change in the angle of the upper housing 21. When the upper housing 21 rotates to the working position, the upper universal joint 25, the telescopic rod 52 and the lower universal joint 16 are coaxially arranged.

[0146] The upper universal joint 25 is provided with a sleeve 521, and the lower universal joint 16 is provided with a spline shaft 522. The sleeve 521 has a groove that matches the spline shaft 522. The spline shaft 522 is slidably disposed in the groove to ensure that the sleeve 521 and the spline shaft 522 can only move relative to each other in the axial direction and will not rotate, so that the torque of the drive component 51 can be transmitted to the upper universal joint 25.

[0147] In this embodiment, the upper transmission system includes two upper drive pulleys 531 and an upper drive belt 541 tensioned by the two upper drive pulleys 531. One upper drive pulley 531 is connected to the accessory 9, and the other upper drive pulley 531 is connected to the upper universal joint 25. When the power of the drive component 51 is transmitted to one of the upper drive pulleys 531 through the lower universal joint 16 and the upper universal joint 25, the accessory 9 can be driven to rotate through the upper drive belt 541 and the other upper drive pulley 531.

[0148] In this embodiment, the lower transmission system includes two primary drive pulleys 532 and a drive belt 542 tensioned by the two primary drive pulleys 532. One primary drive pulley 532 is connected to the drive member 51, and the other primary drive pulley 532 is connected to the lower universal joint 16. This structure is the primary transmission structure of the lower transmission system, which can transmit the power of the drive member 51 to the lower universal joint 16, thereby enabling the accessory 9 to rotate.

[0149] Furthermore, the lower transmission system also includes two secondary transmission pulleys 533 and a lower transmission belt 543 tensioned by the two secondary transmission pulleys 533. One secondary transmission pulley 533 is connected to the mixing bowl 8, and the other secondary transmission pulley 533 is connected to the lower universal joint 16. This structure is a two-stage transmission structure of the lower transmission system, which can transmit the power of the drive component 51 to the lower connecting seat 15, thereby enabling the mixing bowl 8 to rotate.

[0150] It is worth noting that the upper transmission wheel 531, the first-stage transmission wheel 532, and the second-stage transmission wheel 533 are synchronous pulleys, and the upper transmission belt 541, the drive belt 542, and the lower transmission belt 543 are synchronous belts, in order to improve transmission efficiency and reduce energy loss.

[0151] In this embodiment, the unlocking component 42 is a frame structure. To save space, the transmission wheel 53 connected to the upper connecting seat 24 is set inside the frame structure to ensure that the upper connecting seat 24 is in a centered position. The transmission wheel 53 connected to the upper universal joint 25 is offset to avoid the locking component 3, thereby achieving a compact layout inside the bottom shell 213.

[0152] like Figures 20-22 As shown, in order to improve the mixing effect, Attachment 9 is a mixing bowl 91. When whipping a small amount of liquid food substances such as eggs and cream, the liquid food substances will spread evenly at the bottom of the mixing bowl 8, and the overall height is low. The mixing bowl 91 cannot fully contact the food substances, resulting in poor whipping effect or even failure to whip successfully.

[0153] like Figures 20-22 As shown, to solve the above problems, the food processing machine also includes a scraper assembly 7. The scraper assembly 7 is detachably connected to the upper housing 21 and is disposed inside the mixing bowl 8. Along the rotation direction of the mixing bowl 8, the scraper assembly 7 is disposed downstream of the mixing cage 91 and spaced apart from the mixing cage 91. The scraper assembly 7 includes a scraper 71, which abuts against the bottom surface and side wall of the mixing bowl 8.

[0154] In this food processing machine, the mixing bowl 8 can rotate to transfer the liquid food material inside the mixing bowl 8 to the mixing cage 91. The scraper 71 abuts against the bottom and side wall of the mixing bowl 8, thus intercepting the liquid food material inside the mixing bowl 8, causing the liquid food material inside the mixing bowl 8 to gather together, thereby increasing the overall height of the liquid food material, so that the liquid food material can fully contact the mixing cage 91, ensuring that the food material can be fully mixed and whipped by the mixing cage 91.

[0155] In some embodiments, the scraper 71 is spaced apart from the inner wall of the mixing bowl 8, which ensures that the food substances adhering to the inner wall of the mixing bowl 8 are scraped off without scratching the inner wall, thus ensuring the service life of the mixing bowl 8. The distance between the scraper 71 and the inner wall of the mixing bowl 8 is relatively small to prevent a large amount of liquid food substances from passing through the gap between them.

[0156] In this embodiment, the scraper 71 slides against the inner wall of the mixing bowl 8. When the mixing bowl 8 rotates, the scraper 71 can intercept all the liquid food substances, thereby scraping the liquid food substances off the inner wall of the mixing bowl 8, which improves the scraping effect of the scraper 71 on the liquid food substances adhering to the inner wall of the mixing bowl 8.

[0157] like Figures 20-22 As shown, the scraper 71 includes a support portion 711 and a flexible scraper portion 712 disposed on the outer edge of the support portion 711. The flexible scraper portion 712 slides against the bottom surface and / or side surface of the mixing bowl 8. After the flexible scraper portion 712 abuts against the mixing bowl 8, it can undergo elastic deformation, so that the flexible scraper portion 712 can not only fit tightly against the inner wall of the mixing bowl 8, but also avoid scratching the inner wall of the mixing bowl 8, thus extending the service life of the mixing bowl 8 and reducing noise during use.

[0158] Specifically, to improve the scraping effect of the scraper 71, the flexible scraper part 712 slides and abuts against the side wall and bottom surface of the mixing bowl 8 to ensure that liquid food substances rotating with the mixing bowl 8 do not cross the scraper 71. Therefore, to achieve the above purpose, the flexible scraper part 712 is L-shaped. This structure allows the flexible scraper part 712 to elastically abut against the side wall and bottom surface of the mixing bowl 8, and the support part 711 is as close as possible to the side wall and bottom surface of the mixing bowl 8 to ensure that the flexible scraper part 712 can be effectively supported and avoid excessive deformation.

[0159] like Figures 20-22 As shown, the scraper 71 includes a scraper body and a scraping blade 713 disposed on the edge of the scraper body. The scraping blade 713 is in contact with the inner side of the mixing bowl 8 and extends in the opposite direction to the rotation direction of the mixing bowl 8. The scraping blade 713 can scrape liquid food substances away from the mixing bowl 8 as it rotates, thus improving the scraping effect of the scraper 71.

[0160] Specifically, the scraper body includes a support portion 711 and a portion of a flexible scraper portion 712, with the scraper blade edge 713 disposed on the flexible scraper portion 712 and located at the outer edge of the flexible scraper portion 712.

[0161] It is worth noting that when liquid food substances impact the scraper 71 as the mixing bowl 8 rotates, they continue to flow at the scraper 71, making it difficult to gather the liquid food substances together for mixing by the mixing cage 91. Figures 20-22 As shown, the scraper 71 includes a recess 714 facing the mixing cage 91. That is, the side of the scraper 71 facing the mixing cage 91 has a recessed structure, and when liquid food substances enter the recess 714, they will gather in the recess 714.

[0162] like Figure 21 and Figure 22As shown, the recess 714 has a cylindrical surface 715, the axis of which coincides with the rotation axis of the mixing cage 91. This structure ensures that the gap between the mixing range of the mixing cage 91 and the cylindrical surface 715 remains unchanged when the mixing cage 91 rotates, guaranteeing that the mixing cage 91 can continuously mix the liquid food substance entering the recess 714, thereby improving the whipping efficiency.

[0163] In this embodiment, the radius of the cylindrical surface 715 is 2-3 mm larger than the maximum radius of the stirring range of the stirring cage 91. The stirring cage 91 includes multiple spaced-apart stirring wires 911. When the stirring cage 91 rotates, the radius of the area traversed by the part of the stirring wire 911 furthest from the axis of rotation of the stirring cage 91 is the maximum radius of the stirring range. In other words, the minimum gap between the stirring wire 911 and the cylindrical surface 715 is 2-3 mm to ensure sufficient contact between the liquid food substance and the stirring cage. Specifically, the radius of the cylindrical surface 715 can be 2 mm, 2.1 mm, 2.2 mm, 2.3 mm, 2.4 mm, 2.5 mm, 2.6 mm, 2.7 mm, 2.8 mm, 2.9 mm, or 3 mm larger than the maximum radius of the stirring range of the stirring cage 91.

[0164] Furthermore, the stirring wire 911 is spaced apart from the stirring bowl 8 to avoid friction between the stirring wire 911 and the stirring bowl 8, which would cause wear and noise.

[0165] like Figure 22 As shown, the stirring wire 911 includes a vertical section 9111 and a horizontal section 9112. The vertical section 9111 is the outermost part of the stirring wire 911 and is arranged parallel to the side wall of the mixing bowl 8. The horizontal section 9112 is the bottommost part of the stirring wire 911 and is parallel to and spaced apart from the bottom surface of the mixing bowl 8, so as to avoid contact between the mixing cage 91 and the mixing bowl 8 while maximizing the stirring range of the mixing cage 91. The distance between the vertical section 9111 and the rotation axis of the mixing cage 91 is the maximum radius of the stirring range.

[0166] In this embodiment, the minimum distance between the vertical section 9111 and the side of the mixing bowl 8 is 2mm to 3mm. This minimum distance should not be too large or too small. Too large a distance will result in insufficient mixing, while too small a distance will increase contact or resistance between the mixing cage 91 and the mixing bowl 8. Specifically, the minimum distance between the vertical section 9111 and the side of the mixing bowl 8 is 2mm, 2.1mm, 2.2mm, 2.3mm, 2.4mm, 2.5mm, 2.6mm, 2.7mm, 2.8mm, 2.9mm, or 3mm.

[0167] In this embodiment, the minimum distance between the horizontal section 9112 and the side of the mixing bowl 8 is 2mm to 3mm. This minimum distance should not be too large or too small. Too large a distance will result in insufficient mixing, while too small a distance will increase contact or resistance between the mixing cage 91 and the mixing bowl 8. Specifically, the minimum distance between the horizontal section 9112 and the side of the mixing bowl 8 is 2mm, 2.1mm, 2.2mm, 2.3mm, 2.4mm, 2.5mm, 2.6mm, 2.7mm, 2.8mm, 2.9mm, or 3mm.

[0168] In this embodiment, the distance between the axis of the stirring cage 91 and the axis of the stirring bowl 8 is 50mm~60mm, and the distance between the vertical section 9111 and the rotation axis of the stirring cage 91 is 45mm~50mm.

[0169] That is, the maximum radius of the stirring range of the stirring cage 91 is 45mm~50mm, which can be 45mm, 46mm, 47mm, 48mm, 49mm or 50mm. In this embodiment, the maximum radius of the stirring cage 91 is 47mm, so the stirring range of the stirring cage 91 can cover the radius of the stirring bowl 8 as much as possible, thereby increasing the contact area between the stirring cage 91 and the liquid food substance in the stirring bowl 8. Specifically, the distance between the axis of the stirring cage 91 and the axis of the stirring bowl 8 is 50mm, 51mm, 52mm, 53mm, 54mm, 55mm, 56mm, 57mm, 58mm, 59mm or 60mm. In this embodiment, the distance between the axis of the stirring cage 91 and the axis of the stirring bowl 8 is 55.6mm.

[0170] like Figure 20 As shown, the mixing bowl 8 and the mixing cage 91 rotate in the same direction. That is, the mixing bowl 8 and the mixing cage 91 rotate either counterclockwise or clockwise, so that the liquid food material that is thrown out by the mixing cage 91 can return to the mixing range of the mixing cage 91 as the mixing bowl 8 rotates. In addition, it can also increase the movement speed of the liquid food material and improve the mixing efficiency.

[0171] like Figure 22As shown, a protrusion 81 protrudes upwards from the bottom surface of the mixing bowl 8. The highest point of the protrusion 81 is located on the rotation axis of the mixing bowl 8. Vertically, the projection of the scraper 71 onto the bottom surface of the mixing bowl 8 is located within the protrusion 81. It can be understood that, along the radial direction of the mixing bowl 8, the liquid food material closer to the side wall moves at a higher speed, while the movement speed of the liquid food material near the center is close to zero, making it difficult for the liquid food material near the center to be thrown to the position of the mixing cage 91. The protrusion 81 allows the liquid at the center to flow along the protrusion 81 under the action of gravity. When there is a small amount of liquid food material, the protrusion 81 can prevent the liquid food material from stopping at the center of the mixing bowl 8, ensuring that all liquid food material can move to the recess 714 of the scraper 71 as the mixing bowl 8 rotates.

[0172] like Figure 22 and Figure 23 As shown, the scraper assembly 7 also includes a connecting shaft 72 fixedly connected to the scraper 71. The axis of the connecting shaft 72 is parallel to the rotation axis of the mixing cage 91, and both the connecting shaft 72 and the rotation axis of the mixing cage 91 are located on the same side of the rotation axis of the mixing bowl 8. This structure allows the scraper 71 to gather food substances on one side of the rotation axis of the mixing bowl 8, so that the mixing cage 91 can fully mix the food substances.

[0173] Specifically, the distance between the connecting shaft 72 and the rotation axis of the mixing bowl 8 is 5mm to 10mm. This distance needs to be less than the radius of the convex 81 to ensure that the scraper 71 can be partially located within the range of the convex 81, thereby improving the scraping effect of the scraper 71 and enabling the scraper 71 to scrape and gather all the food material located on one side of the rotation axis of the mixing bowl 8 together.

[0174] like Figure 24 As shown, a top cover 82 is provided on the mixing bowl 8. The top cover 82 is fastened to the mixing bowl 8 to prevent liquid food substances from splashing out of the mixing bowl 8 and polluting the environment during mixing. In order to facilitate the addition of liquid food substances, the top cover 82 includes a fixing part 821 and a closing part 822. The fixing part 821 is fixedly connected to the mixing bowl 8 or the upper shell 21. The scraper assembly 7 and the mixing cage 91 both extend into the mixing bowl 8 through the fixing part 821. The closing part 822 is hinged to the fixing part 821 to open or close the opening formed by the mixing bowl 8 and the fixing part 821.

[0175] like Figure 25 and Figure 26 As shown, the main unit includes a fixed shaft 26, on which a locking nut 27 is rotatably mounted. The scraper assembly 7 also includes a connecting shaft 72 fixedly connected to the scraper 71. The connecting shaft 72 has a threaded section 721, and the locking nut 27 is threadedly connected to the threaded section 721 to fix the connecting shaft 72 to the fixed shaft 26.

[0176] The fixed shaft 26 is disposed inside the upper housing 21. A limit ring is provided at the bottom end of the fixed shaft 26. The locking nut 27 includes a bottom ring 271 and a locking section 272. The bottom ring 271 is sleeved on the fixed shaft 26 and abuts against the limit ring. The connecting shaft 72 passes through the locking section 272 and is threadedly connected to the locking section 272. As the locking nut 27 rotates, the connecting shaft 72 can approach and abut against the fixed shaft 26, thereby completing the locking between the connecting shaft 72 and the fixed shaft 26.

[0177] like Figure 23 and Figure 26 As shown, the fixed shaft 26 has a locking groove 261, and the end of the connecting shaft 72 is provided with a locking platform 722. The outer diameter of the locking platform 722 gradually increases from top to bottom. The locking platform 722 is disposed in the locking groove 261 and abuts against the inner wall of the locking groove 261. The locking platform 722 has a frustum structure. The setting of the locking platform 722 enables the connecting shaft 72 to abut against the inner wall of the locking groove 261 during the process of entering the locking groove 261, thereby completing the fixation. It can also achieve radial limitation of the connecting shaft 72, ensuring the accurate position of the scraper assembly 7 in the mixing bowl 8.

[0178] Furthermore, the inner wall of the locking groove 261 has a contact surface, which is inclined, and the inclination direction and angle of the contact surface are the same as those of the side wall of the locking platform 722. That is to say, when the locking platform 722 enters the locking groove 261, the side wall of the locking platform 722 can fit against the inner wall of the locking groove 261. When the locking nut 27 is tightened, the force between the connecting shaft 72 and the fixed shaft 26 is evenly distributed by the contact surface. Moreover, since the connecting shaft 72 and the fixed shaft 26 are in surface contact, it can be ensured that the axial direction of the connecting shaft 72 is vertically extended, thereby ensuring the reliability of the gap size between the recess 714 of the scraper 71 and the stirring cage 91, and avoiding interference or excessive gap between the two.

[0179] like Figure 23 and Figure 26 As shown, the side wall of the locking platform 722 is provided with an anti-rotation pin 723, and the side wall of the fixed shaft 26 is provided with an anti-rotation groove 262, with the anti-rotation pin 723 partially located within the anti-rotation groove 262. The anti-rotation pin 723 can position the installation angle of the scraper assembly 7, ensuring the accuracy of the scraper 71's position within the mixing bowl 8, and ensuring the reliability of the gap size between the recess 714 of the scraper 71 and the mixing cage 91, thus avoiding interference or excessive gap between the two.

The content of this specification should not be construed as a limitation of this utility model.
