[0069] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0070] This embodiment provides a food processing machine for processing food substances located in a container. For example... Figure 1 and Figure 2 As 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.

[0071] 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.

[0072] 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.

[0073] It is worth mentioning that in the embodiment, the accessory 9 is detachably connected with the horizontal head 211, that is, the type of the accessory 9 can be replaced according to the type and processing requirement of the food substance in the mixing bowl. For example, the accessory 9 can be a dough hook 92, which is a spiral structure and can perform a dough mixing operation on the flour and water in the mixing bowl 8. The accessory 9 further includes a dough guard 93 used in cooperation with the dough hook 92, which is detachably arranged on the horizontal head 211 and extends along the radial direction of the mixing bowl 8, and the dough hook 92 is located between the dough guard 93 and the side wall of the mixing bowl 8. That is, the dough guard 93 forms a flow channel in the interior of the mixing bowl 8, which extends along the circumferential direction of the mixing bowl 8 around the dough guard 93, and the flour and water move around the dough guard 93 in the flow channel, and the dough hook 92 is equivalent to being blocked in the moving path of the flour and water, so as to improve the dough mixing effect.

[0074] In some embodiments, the accessory 9 can also be a whipping cage 91, which can perform a whipping operation on the eggs and cream in the mixing bowl 8.

[0075] In the embodiment, the lower support arm assembly 112 and the upper support arm assembly 212 form a vertical support arm, which allows the horizontal base 111 and the horizontal head 211 to be spaced apart to provide space for the accessory 9 and the mixing bowl 8. Moreover, the upper support arm assembly 212 is pivotally connected with the lower support arm assembly 112 to allow the upper housing 21 to have an open position and a working position. When the upper housing 21 is in the open position, the accessory 9 is located outside the mixing bowl 8, and the horizontal head 211 does not block the mixing bowl 8, so that the mixing bowl 8 can be easily removed to take out or put in the food substance. When the upper housing 21 is in the working position, the accessory 9 extends into the mixing bowl 8, and the horizontal head 211 is located above the mixing bowl 8, so that the food substance in the mixing bowl 8 can be stirred, and the food processor can be conveniently stored when not in use, thereby saving space.

[0076] It is worth mentioning that the upper housing 2 and the lower housing 1 of the food processor are provided with a decorative cover 13 to cover the internal structure and ensure the appearance. When the upper housing 2 and the lower housing 1 are closed, the decorative cover 13 is hidden in the interior of the lower housing 1.

[0077] In the embodiment, since the mixing bowl 8 and the accessory 9 need to be driven to rotate at the same time, the food processor needs to use a driving motor with large power, which increases the size of the driving motor, so the driving motor can only be installed in the interior of the lower housing 1, usually in the lower support arm assembly 112. This results in that the interior space of the lower housing 1 is limited, and there is not enough space to accommodate the decorative cover 13, so a smaller decorative cover 13 has to be selected, which causes the internal structure to be exposed when the upper housing 2 and the lower housing 1 are opened, or the opening angle between the upper housing 2 and the lower housing 1 needs to be reduced, which affects the user experience.

[0078] As Figures 3-12 shown to solve the above problems, the food processor provided by the embodiment includes a shielding structure 12 arranged on the lower shell 11, the shielding structure 12 is provided with 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 shell 21 is in the working position, part of the decorative cover 13 and part of the shielding structure 12 are located in the upper shell 21. The upper body 2 further includes a driving shaft 22 connected with the upper shell 21. During the process that the user rotates the upper shell 21 from the working position to the open position, the driving shaft 22 is spaced apart from the driven part and then abuts against the driven part, so as to drive the decorative cover 13 to rotate out of the receiving groove 121 through the driven part, and the decorative cover 13 shields the gap between the upper shell 21 and the shielding structure 12. One end of the driving shaft 22 is provided with knurls, and the knurls are fixedly connected with the upper shell 21. The knurls can make the shaft hole fit more firmly and prevent the driving shaft 22 from slipping.

[0079] In the food processor, the shielding structure 12 is arranged on the lower shell 11, which reduces the size of the gap between the upper shell 21 and the lower shell 11 when the upper shell 21 is in the open position, so that the decorative cover 13 is more easily shielded. During the process that the upper shell 21 is rotated to the open position, when the shielding structure 12 can shield the gap between the upper shell 21 and the lower shell 11, the driving shaft 22 is spaced apart from the driven part, and the decorative cover 13 remains stationary. When the upper shell 21 and the shielding structure 12 are no longer overlapped, the driving shaft 22 abuts against the driven part, and the decorative cover 13 rotates with the upper shell 21 to shield the gap between the upper shell 21 and the shielding structure 12. Moreover, by arranging the accommodating space on the upper body 2, part of the decorative cover 13 and part of the shielding structure 12 are located in the upper shell 21 when the upper shell 21 is in the working position, which reduces the size of the space invaded by the decorative cover 13 into the lower shell 11, so that the decorative cover 13 of the food processor can have sufficient size to shield the gap between the upper shell 21 and the lower shell 11.

[0080] The food processor can shield the internal structure without reducing the opening angle of the upper body 2 and the lower body 1, ensure that the internal structure is not exposed, and improve the user experience.

[0081] In the embodiment, the shielding structure 12 is provided with a rotating shaft hole connected with the decorative cover 13, and 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 positional relationship with the shielding structure 12 during rotation, and ensure that the decorative cover 13 can be rotated 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.

[0082] As Figure 4 andFigure 5 As shown, the shielding structure 12 and the decorative cover 13 are in rotational movement through the pin shaft 122 which is arranged in the rotating shaft hole. The pin shaft 122 arranged in the rotating shaft hole can ensure the stability of the decorative cover 13 when rotating relative to the shielding structure 12, and the pin shaft 122 has high strength and is convenient to replace, thereby prolonging the service life and reducing the maintenance difficulty.

[0083] In order to limit the rotation range of the decorative cover 13, the lower shell 11 is further provided with a limiting body 113, and the decorative cover 13 is provided with a position positioning protrusion 133. When the upper shell 21 is in the working position, the position positioning protrusion 133 is away from the limiting body 113. When the upper shell 21 is in the open position, the front side of the position positioning protrusion 133 abuts against the rear end surface of the limiting body 113.

[0084] As shown in Figure 6 , Figures 10-12 , the decorative cover 13 is provided with a driving groove 131 which forms a driven part. The driving shaft 22 is provided with a driving ring 23 at the end away from the upper shell 21. The driving shaft 22 is arranged in the driving groove 131. The process of rotating the upper shell 2 from the working position to the open position is divided into a first process and a second process. In the first process, the driving ring 23 is arranged in the driving groove 131 with a spacing, and the decorative cover 13 remains stationary. In the second process, the driving ring 23 abuts against at least one side of the driving groove 131, and the decorative cover 13 rotates with the upper shell 2.

[0085] In the process of rotating the upper shell 21 to the open position, the upper shell 21 first experiences the first process. At this time, the driving ring 23 does not abut against the side of the driving groove 131, that is, at this time, the decorative cover 13 remains stationary in the containing groove 121. When the upper shell 21 rotates to the second process, the driving ring 23 abuts against at least one side of the driving groove 131, so that the decorative cover 13 rotates with the upper shell 21, thereby making the decorative cover 13 rotate out of the driving groove 131 to shield the gap between the upper shell 21 and the lower shell 11. Moreover, since the driving ring 23 does not abut against at least one side of the driving groove 131 all the time, the coincidence range of the decorative cover 13 and the shielding structure 12 is larger in structure, thereby further saving space.

[0086] It is worth mentioning that when the upper shell 21 rotates to the intersection position 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 shield the gap between the upper shell 21 and the shielding structure 12, thereby ensuring the appearance.

[0087] As shown in Figure 3 , Figure 6 and Figure 13As shown, the decorative cover 13 is provided with a baffle 132 at both ends along the length direction of the rotation axis of the decorative cover 13, and the baffle 132 is located on the inner side of the side wall of the upper shell 21. When the upper shell 21 is in the open position, the baffle 132 overlaps with the side wall of the upper shell 21 to avoid the offset of the decorative cover 13. The arrangement of the baffle 132 enables the upper shell 21 to still limit the decorative cover 13 in the open position, avoids the offset of the decorative cover 13, and ensures that the upper shell 21 does not interfere with the decorative cover 13 when the user rotates the upper shell 21 from the open position to the working position.

[0088] As shown in Figure 12 and Figure 13 The upper shell 21 includes a bottom shell 213, and the decorative cover 13 is located below the bottom shell 213. The bottom shell 213 is provided with a receiving hole 2131, and the baffle 132 is arranged in the receiving hole 2131 when the upper shell 21 is in the working position. The receiving hole 2131 provided in the bottom shell 213 can accommodate the baffle 132 of the decorative cover 13 when the upper shell 21 is in the working position, so as to avoid the interference between the baffle 132 and the bottom shell 213, which causes the upper shell 21 to be unable to rotate to the working position.

[0089] As shown in Figures 14-16 The food processor further includes a locking assembly 3, and the locking assembly 3 includes a fixing seat 31 and a locking shaft 32. The fixing seat 31 is connected with the upper shell 21, and the locking shaft 32 is slidingly arranged in the fixing seat 31. The lower body 1 further includes a locking hook 14 connected with the lower shell 11, and the locking shaft 32 is clamped and fixed with the locking hook 14 when the upper shell 21 is in the working position.

[0090] The locking shaft 32 of the locking assembly 3 can slide relative to the fixing seat 31. When the upper shell 21 is in the working position, the locking shaft 32 is clamped and fixed with the locking hook 14 by sliding, so as to lock the upper shell 21 in the working position and ensure the stability of the upper shell 21 when the food material in the mixing bowl 8 is stirred.

[0091] Further, the locking assembly 3 further includes a first elastic member 33, and the two ends of the first elastic member 33 abut against the fixing seat 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 locking force to the locking shaft 32, so as to ensure that the locking shaft 32 always abuts against the locking hook 14, and avoid the disengagement between the locking shaft 32 and the locking hook 14 during work, which causes the unlocking of the upper shell 21 and causes safety accidents.

[0092] As shown in Figure 13 and Figure 14As shown, the food processor further comprises an unlocking assembly 4, which comprises an unlocking slider 41 and an unlocking piece 42. The unlocking piece 42 is rotationally arranged in the upper shell 21, and a first end of the unlocking piece 42 is in sliding abutment with the locking shaft 32. The unlocking slider 41 is slidingly arranged in the upper shell 21 and is in abutment with a second end of the unlocking piece 42. The unlocking slider 41 is capable of driving the unlocking piece 42 to rotate, so as to make the locking shaft 32 disengage from the locking clasp 14.

[0093] The user can push the unlocking slider 41 to make the unlocking piece 42 rotate and push the locking shaft 32, so as to make the locking shaft 32 compress the first elastic piece 33 and disengage from the locking clasp 14. Thus, the user can rotate the upper shell 21 to the open position, so as to facilitate the taking and placing of the stirring bowl 8. It is worth mentioning that the user needs to continuously press the unlocking slider 41 until the user feels that the locking shaft 32 disengages from the locking clasp 14.

[0094] Further, the unlocking slider 41 comprises a trigger column 412 and a guide column 411. Both the trigger column 412 and the guide column 411 are arranged through the upper shell 21, and the guide column 411 is in guiding cooperation with the upper shell 21. The trigger column 412 is in sliding abutment with the second end of the unlocking piece 42. An end of the guide column 411 is threadedly connected with a limiting screw. A screw cap of the limiting screw is capable of being in abutment with the upper shell 21 to limit the unlocking slider 41, so as to avoid the unlocking slider 41 from disengaging from the upper shell 21.

[0095] As shown in Figs. 1 and 2, Figure 15 and Figure 16 As shown, a sheath 43 is arranged on the first end of the unlocking piece 42, and the sheath 43 is in sliding abutment with the locking shaft 32. In order to ensure the strength of the unlocking piece 42, the unlocking piece 42 is made of metal material. If the unlocking piece 42 is directly in sliding abutment with the locking shaft 32, it is easy to be abraded and affect the service life, and noise is also generated. The sheath 43 is made of plastic material with good abrasion resistance. The sheath 43 is in sliding abutment with the locking shaft 32, so that the relative movement between the unlocking piece 42 and the locking shaft 32 is smoother, and noise is not generated.

[0096] In this embodiment, when the locking assembly 3 needs to be unlocked, the unlocking slider 41 needs to be moved upward. At this time, the unlocking piece 42 rotates, and the first end of the unlocking piece 42 can push the locking shaft 32, so as to make the locking shaft 32 disengage from the locking clasp 14.

[0097] Generally, the sliding direction of the locking shaft 32 is horizontal or substantially horizontal, while the moving direction of the first end of the unlocking member 42 is substantially vertical when the unlocking member 42 rotates. In order to enable the unlocking member 42 to drive the locking shaft 32 to move a sufficient distance to ensure that the locking shaft 32 can be disengaged from the locking catch 14, the sheath 43 has a driving slope 421, which drives the locking shaft 32 to disengage from the locking catch 14 when the first end of the unlocking member 42 moves in the unlocking direction.

[0098] Due to the presence of the driving slope 421, when the first end moves in the substantially vertical direction, the driving force in the moving direction of the locking shaft 32 can be applied to the locking shaft 32, thereby pushing the locking shaft 32 to move. Specifically, in the present embodiment, taking the case that the upper shell 21 is in the working position as an example, in the direction from top to bottom, the driving slope 421 is inclined in the direction away from the unlocking direction of the locking shaft 32, so when the unlocking slider 41 is pressed, the first end of the unlocking member 42 moves downward, the locking shaft 32 slides along the driving slope 421 and disengages from the locking catch 14.

[0099] It is worth noting that the sheath 43 and the unlocking member 42 are made of different materials, and the hardness of the unlocking member 42 is greater than that of the sheath 43, so as to ensure that the sheath 43 can push the locking shaft 32 under the support of the unlocking member 42, and the sheath 43 can also reduce the wear between the sheath 43 and the locking shaft 32, and improve the lubricity between the sheath 43 and the locking shaft 32, thereby reducing the noise during unlocking. Specifically, the unlocking member 42 can be made of metal, plastic or the like, and the sheath 43 can be made of rubber, polyurethane or the like.

[0100] As shown in Figure 14 and Figure 17 , the unlocking member 42 comprises a frame structure, the unlocking assembly 4 comprises two unlocking sliders 41, and the two unlocking sliders 41 are arranged on opposite sides of the upper shell 21 and abut against the frame structure. The arrangement of the two unlocking members 42 enables the user to unlock the upper shell 21 with one hand or both hands, and when the user unlocks the upper shell 21 with both hands, the force is more symmetrical, and the rotation of the unlocking member 42 is more smooth. The arrangement of the frame structure not only enables the unlocking member 42 to avoid other structures inside the upper shell 21, but also improves the strength of the unlocking member 42, so that the unlocking member 42 is not easy to deform, and ensures that a single unlocking slider 41 can drive the unlocking member 42 to rotate to realize the unlocking function.

[0101] As shown in Figure 14 and Figure 17As shown, the unlocking piece 42 is provided with a rotating shaft 422, the unlocking piece 42 is rotationally connected with the upper shell 21 through the rotating shaft 422, the first end and the second end are located on two sides of the rotating shaft 422 respectively, and the moving direction of the second end is opposite to that of the first end. That is, the unlocking piece 42 plays a role of a lever, when the user presses the unlocking slider 41 in one direction, the movement direction of the second end of the unlocking piece 42 is the same as that of the unlocking slider 41, and the movement direction of the first end of the unlocking piece 42 is opposite to that of the unlocking slider 41.

[0102] In the embodiment, the distance L between the trigger column 412 and the rotating shaft 422 is 30mm-50mm. The distance is a force arm for the unlocking slider 41 to drive the unlocking piece 42 to rotate, and it is not suitable to be too large or too small. If it is too small, the user will find it difficult to press the unlocking slider 41, and if it is too large, the unlocking stroke of the unlocking slider 41 will be too long, which is inconvenient to use. Specifically, the distance between the trigger column 412 and the rotating shaft 422 can be 30mm, 32mm, 34mm, 36mm, 38mm, 40mm, 42mm, 44mm, 46mm, 48mm or 50mm.

[0103] When the user rotates the upper shell 21 to place it in the open position, it can be necessary to put or take out food substances into or from the mixing bowl 8, or to clean the mixing bowl 8, at this time, it is necessary to ensure the stability of the position of the upper shell 21. As shown in Figure 3 、 Figure 4 、 Figure 9 and Figure 16 In order to achieve the above purpose, in the embodiment, the lower body 1 further comprises a limiting piece 17, the limiting piece 17 is connected with the lower shell 11, the limiting piece 17 is provided with a limiting slot 171, when the upper shell 21 is in the open position, the upper body 2 rotates around the pivot, and the locking shaft 32 is clamped into the limiting slot 171.

[0104] In the embodiment, it needs a process to rotate the upper shell 21 from the working position to the open position and from the open position to the working position.

[0105] When converting from the working position to the open position, the unlocking slider 41 needs to be pressed down first, so that the unlocking piece 42 rotates around the rotating shaft 422, and the locking shaft 32 slides away from the locking clamping hook 14 under the drive of the unlocking piece 42, at this time, the unlocking slider 41 can be released, and the upper shell 21 rotates around the pivot to the open position; during the rotation of the upper shell 21, the locking shaft 32 returns to the initial state under the pressure release of the first elastic piece 33; with the rotation of the upper body 2 around the pivot, the locking shaft 32 approaches and clamps into the limiting slot 171, at this time, it is in the open position, and the locking shaft 32 can be limited by the limiting slot 171 to fix the upper shell 21 in the open position.

[0106] When converting from the open position to the working position, the unlocking slider 41 needs to be pressed down first, so that the unlocking member 42 rotates around the rotating shaft 422, and the locking shaft 32 slides away from the limiting groove 171 on the limiting member 17 under the drive of the unlocking member 42. At this time, the unlocking slider 41 can be released, and the upper shell 21 will rotate around the pivot to the open position. In the process of rotating the upper shell 21, the locking shaft 32 returns to the initial state under the pressure release of the first elastic member 33. With the rotation of the upper body 2 around the pivot, the locking shaft 32 approaches and is clamped into the locking clamping hook 14. At this time, it is in the working position, and the locking shaft 32 can be limited by the locking clamping hook 14 to fix the upper shell 21 at the working position.

[0107] In summary, when the upper shell 21 is in the open position or the working position, the first elastic member 33 is in the elongated state. When the locking shaft 32 is driven by the sheath 43 on the unlocking member 42, the first elastic member 33 is in the compressed state, so that the locking shaft 32 is separated from the limiting groove 171 or the locking clamping hook 14.

[0108] The limiting member 17 is fixed on the lower shell 11, and the limiting groove 171 of the limiting member 17 can limit the upper shell 21 by the locking shaft 32, so that the upper shell 21 can be stably stopped at the open position. It is worth noting that when the locking shaft 32 is separated from the locking clamping hook 14, the button does not need to be pressed all the time, but the upper shell 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 shell 21 to the working position, you can still press the unlocking slider 41 to achieve it.

[0109] As shown in Figure 10 The food processor further includes a second elastic member 19 configured to drive the upper shell 21 to rotate from the working position to the open position and stop between the working position and the open position. That is, when the unlocking assembly 4 unlocks the locking assembly 3, the upper shell 21 will rotate and open under the drive of the second elastic member 19, ensuring that the locking shaft 32 will not be reconnected with the locking clamping hook 14 after the user releases the locking slider. Moreover, since the second elastic member 19 only stops the upper shell 21 between the working position and the open position, it can prevent the locking shaft 32 from colliding with the limiting member 17, thereby protecting the service life of the food processor. Finally, the user needs to manually rotate the upper shell 21 to the open position to lock the upper shell 21 by the limiting member 17.

[0110] As shown in Figure 3As shown, the lower housing 11 is provided with a buffer pad 18, and when the upper housing 21 is in the open position, the upper housing 21 is pressed against the buffer pad 18 of the lower housing 11. Generally, when the upper housing 21 is in the open position, the redundant amount between part of the upper housing 21 and the lower housing 11 is small, and if the user rotates the upper housing 21 at a high speed, it is easy to cause the upper housing 21 to collide with the lower housing 11. 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, effectively avoiding the collision between the upper housing 21 and the lower housing 11 to cause damage and noise.

[0111] In order to ensure safety, when the upper housing 21 is not in the working position, the food processor cannot be started, for example, Figure 17 and Figure 18 As shown, in order to achieve the above purpose, the upper housing 21 is provided with a sensing assembly 6, which includes a mounting seat 61, a sliding seat 62 and a third elastic member 63. The mounting seat 61 is fixedly connected with the bottom shell 213, and the sliding seat 62 is slidingly arranged in the mounting seat 61. The sliding seat 62 is connected with a detection column 64 penetrating through the bottom shell 213, and the sliding seat 62 is provided with a sensing member 65. The two ends of the third elastic member 63 abut against the mounting seat 61 and the sliding seat 62 respectively to drive the connecting column to extend out of the bottom shell 213.

[0112] When the upper housing 21 is in the working position, the lower housing 11 abuts against the detection column 64 to drive the sliding seat 62 to slide, and at this time, the distance between the sensing end of the sensing member 65 and the bottom shell 213 is increased. When the upper housing 21 is not in the working position, the elastic member drives the detection column 64 to extend out of the bottom shell 213, and at this time, the distance between the sensing end of the sensing member 65 and the bottom shell 213 is smallest. Through the above structure, the position of the upper housing 21 can be determined by the food processor.

[0113] As shown in Figure 8 and Figures 20-22 In order to drive the stirring bowl 8 and the accessory 9 to rotate, the food processor further comprises a driving assembly 5, which includes a driving member 51 and a transmission system. The transmission system is installed in the lower body 1 and / or the upper body 2, and is operably connected to the driving member 51 and associated with the stirring bowl 8 to make the stirring bowl 8 rotate. The driving member 51 can drive the stirring bowl 8 to rotate through the transmission system, ensuring the stirring of food substances in the stirring bowl 8. In this embodiment, the transmission system is also in transmission connection with the accessory 9, so as to improve the stirring effect of food substances in the stirring bowl 8.

[0114] Specifically, the transmission system comprises an upper transmission system and a lower transmission system, the upper transmission system is in transmission connection with the accessory 9, the lower transmission system is in transmission connection with the stirring bowl 8, the upper transmission system and the lower transmission system are in synchronous movement and are both in transmission connection with the driving member 51. The upper transmission system and the lower transmission system can respectively transmit the power of the driving member 51 to the accessory 9 and the stirring bowl 8, and the upper transmission system and the lower transmission system can make the accessory 9 and the stirring bowl 8 move synchronously to ensure the stirring effect.

[0115] In the embodiment, the transmission system further comprises a universal joint assembly, the universal joint assembly is in transmission connection with the upper transmission system and the lower transmission system. Since the upper shell 21 and the lower shell 11 of the food processor can relatively rotate, the power transmission direction between the upper transmission system and the lower transmission system will change, so the universal joint assembly is needed to avoid the upper transmission system and the lower transmission system from being stuck.

[0116] Specifically, the lower shell 11 is rotationally provided with a lower connecting seat 15 and a lower universal joint 16, the lower connecting seat 15 is detachably connected with the stirring bowl 8, the lower connecting seat 15 is in transmission connection with the lower universal joint 16, the upper shell 21 is rotationally provided with an upper connecting seat 24 and an upper universal joint 25, the upper connecting seat 24 is detachably connected with the accessory 9, the upper connecting seat 24 is in transmission connection with the upper universal joint 25, one end of the upper universal joint 25 is sleeved with one end of the lower universal joint 16 to form an extension rod 52.

[0117] When the upper shell 21 rotates relative to the lower shell 11, the extension rod 52 also expands and contracts, the upper universal joint 25 and the lower universal joint 16 at both ends of the extension rod 52 relatively rotate, and the length of the extension rod 52 changes to adapt to the change of the angle of the upper shell 21, when the upper shell 21 rotates to the working position, the upper universal joint 25, the extension rod 52 and the lower universal joint 16 are coaxially arranged.

[0118] Among them, the upper universal joint 25 is provided with a sleeve 521, the lower universal joint 16 is provided with a spline shaft 522, the sleeve 521 is provided with a sliding groove matched with the spline shaft 522, and the spline shaft 522 is slidingly arranged in the sliding groove, so that the sleeve 521 and the spline shaft 522 can only relatively move in the axial direction and cannot rotate, thereby the torque of the driving member 51 can be transmitted to the upper universal joint 25.

[0119] In the embodiment, the upper transmission system comprises two upper transmission wheels 531 and an upper transmission belt 541 tensioned by the two upper transmission wheels 531, one of the upper transmission wheels 531 is connected with the accessory 9, and the other of the upper transmission wheels 531 is connected with the upper universal joint 25. When the power of the driving member 51 is transmitted to one of the upper transmission wheels 531 through the lower universal joint 16 and the upper universal joint 25, the accessory 9 can be driven to rotate through the upper transmission belt 541 and the other of the upper transmission wheels 531.

[0120] In the embodiment, the lower transmission system comprises two primary transmission wheels 532 and a driving belt 542 tensioned by the two primary transmission wheels 532, one of the primary transmission wheels 532 is connected with the driving member 51, and the other is connected with the lower universal joint 16. The structure is a primary transmission structure of the lower transmission system, which can transmit the power of the driving member 51 to the lower universal joint 16, so that the accessory 9 can rotate.

[0121] Further, the lower transmission system further comprises two secondary transmission wheels 533 and a lower transmission belt 543 tensioned by the two secondary transmission wheels 533, one of the secondary transmission wheels 533 is connected with the stirring bowl 8, and the other is connected with the lower universal joint 16. The structure is a secondary transmission structure of the lower transmission system, which can transmit the power of the driving member 51 to the lower connecting seat 15, so that the stirring bowl 8 can rotate.

[0122] It is worth noting that the upper transmission wheel 531, the primary transmission wheel 532 and the secondary transmission wheel 533 are synchronous wheels, and the upper transmission belt 541, the driving belt 542 and the lower transmission belt 543 are synchronous belts, so as to improve the transmission efficiency and reduce the energy loss.

[0123] In the embodiment, the unlocking member 42 is a frame structure, and the transmission wheel 53 connected with the upper connecting seat 24 is arranged in the frame structure to save space, so as to ensure that the position of the upper connecting seat 24 is in the central state, and the transmission wheel 53 connected with the upper universal joint 25 is arranged offset to avoid the locking assembly 3, so as to realize the compact layout inside the bottom shell 213.

[0124] As shown in Figures 20-22 In order to improve the stirring effect, the accessory 9 is a stirring cage 91. When a small amount of liquid food material such as egg and cream is whipped, the liquid food material is spread on the bottom of the stirring bowl 8, and the overall height is low, so that the stirring cage 91 cannot fully contact the food material, resulting in poor whipping effect or even failure to whip smoothly.

[0125] As shown in Figures 20-22 In order to solve the above problem, the food processor further comprises a scraper assembly 7, which is detachably connected to the upper shell 21 and arranged in the stirring bowl 8, and along the rotation direction of the stirring bowl 8, the scraper assembly 7 is arranged downstream of the stirring cage 91 and spaced apart from the stirring cage 91, the scraper assembly 7 comprises a scraper 71, which abuts the bottom surface and the side wall of the stirring bowl 8.

[0126] The food processor, the stirring bowl 8 can be transmitted to the stirring cage 91 by rotating to the liquid food material in the stirring bowl 8, and the scraper 71 abuts the bottom surface and the side wall of the stirring bowl 8, so that the liquid food material in the stirring bowl 8 can be intercepted, the liquid food material in the stirring bowl 8 is gathered, thereby improving the overall height of the liquid food material, and the liquid food material is fully contacted with the stirring cage 91, so that the food material can be fully stirred and whipped by the stirring cage 91.

[0127] In some embodiments, the scraper 71 is spaced apart from the inner wall of the stirring bowl 8, which can ensure that the food material attached to the inner wall of the stirring bowl 8 is scraped off without scratching the inner wall of the stirring bowl 8, thereby ensuring the service life of the stirring bowl 8. The distance between the scraper 71 and the inner wall of the stirring bowl 8 is small to avoid a large amount of liquid food material passing through the gap between the scraper 71 and the inner wall of the stirring bowl 8.

[0128] In the embodiment, the scraper 71 is in sliding abutment with the inner wall of the stirring bowl 8, and when the stirring bowl 8 rotates, the scraper 71 can intercept all the liquid food material, thereby scraping off the liquid food material from the inner wall of the stirring bowl 8, and improving the scraping effect of the scraper 71 on the liquid food material attached to the inner wall of the stirring bowl 8.

[0129] As shown in Figures 20-22 The scraper 71 includes a support portion 711 and a flexible scraper portion 712 provided at the outer edge of the support portion 711, and the flexible scraper portion 712 is in sliding abutment with the bottom surface and / or the side wall of the stirring bowl 8. After the flexible scraper portion 712 abuts the stirring bowl 8, it can be elastically deformed, so that the flexible scraper portion 712 can closely fit the inner wall of the stirring bowl 8 and avoid scratching the inner wall of the stirring bowl 8, thereby prolonging the service life of the stirring bowl 8 and reducing noise during use.

[0130] Specifically, in order to improve the scraping effect of the scraper 71, the flexible scraper portion 712 is in sliding abutment with the side wall and the bottom surface of the stirring bowl 8 to ensure that the liquid food material rotating with the stirring bowl 8 cannot pass over the scraper 71. Therefore, in order to achieve the above purpose, the flexible scraper portion 712 is L-shaped, which enables the flexible scraper portion 712 to be in elastic abutment with the side wall and the bottom surface of the stirring bowl 8, and the support portion 711 is as close as possible to the side wall and the bottom surface of the stirring bowl 8 to ensure that the flexible scraper portion 712 can be effectively supported to avoid excessive deformation.

[0131] As shown in Figures 20-22As shown, the scraper 71 includes a scraper body and a scraper blade edge 713 arranged at the edge of the scraper body, the scraper blade edge 713 is in contact with the inner side of the mixing bowl 8, and the scraper blade edge 713 extends in the opposite direction of the rotation direction of the mixing bowl 8. The arrangement of the scraper blade edge 713 can scrape the liquid food material rotating with the mixing bowl 8 away from the mixing bowl 8, thereby improving the scraping effect of the scraper 71.

[0132] Specifically, the scraper body includes a support part 711 and a part of a flexible scraping part 712, and the scraper blade edge 713 is arranged at the flexible scraping part 712 and located at the outer edge of the flexible scraping part 712.

[0133] It is worth noting that when the liquid food material hits the scraper 71 with the rotation of the mixing bowl 8, it will continue to flow at the scraper 71, and it is difficult to gather the liquid food material together for stirring by the stirring cage 91. As shown in Figure 21 As shown, the scraper 71 includes a recess 714 facing the stirring cage 91. That is, the side of the scraper 71 facing the stirring cage 91 has a concave structure, and when the liquid food material enters the recess 714, it will be gathered in the recess 714.

[0134] As shown in Figure 22 and Figure 22 As shown, the recess 714 has a cylindrical surface 715, and the axis of the cylindrical surface 715 coincides with the rotation axis of the stirring cage 91. This structure makes the gap between the stirring range of the stirring cage 91 and the cylindrical surface 715 remain unchanged when the stirring cage 91 rotates, ensuring that the stirring cage 91 can continuously stir the liquid food material entering the recess 714, thereby improving the whipping efficiency.

[0135] 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 a plurality of stirring wires 911 arranged at intervals, and the radius of the area turned by the part of the stirring wire 911 farthest from the rotation axis of the stirring cage 91 when the stirring cage 91 rotates is the maximum radius of the stirring range. That is, the minimum gap between the stirring wire 911 and the cylindrical surface 715 is 2-3 mm, so as to ensure sufficient contact with the liquid food material. 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.

[0136] Further, the stirring wires 911 are arranged at intervals from the mixing bowl 8 to avoid friction between the stirring wires 911 and the mixing bowl 8, thereby avoiding wear and noise.

[0137] As shown in Figure 20As 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 in parallel with the side wall of the stirring bowl 8. The horizontal section 9112 is the bottommost part of the stirring wire 911 and is arranged in parallel with and spaced apart from the bottom surface of the stirring bowl 8 to avoid contact between the stirring cage 91 and the stirring bowl 8 while maximizing the stirring range of the stirring cage 91. The distance between the vertical section 9111 and the rotation axis of the stirring cage 91 is the maximum radius of the stirring range.

[0138] In this embodiment, the minimum distance between the vertical section 9111 and the side surface of the stirring bowl 8 is 2-3 mm. The minimum distance between the vertical section 9111 and the side surface of the stirring bowl 8 should not be too large or too small. If it is too large, the stirring will be insufficient. If it is too small, the stirring cage 91 and the stirring bowl 8 will be in contact or the resistance will increase. Specifically, the minimum distance between the vertical section 9111 and the side surface of the stirring bowl 8 is 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.

[0139] In this embodiment, the minimum distance between the horizontal section 9112 and the side surface of the stirring bowl 8 is 2-3 mm. The minimum distance between the horizontal section 9112 and the side surface of the stirring bowl 8 should not be too large or too small. If it is too large, the stirring will be insufficient. If it is too small, the stirring cage 91 and the stirring bowl 8 will be in contact or the resistance will increase. Specifically, the minimum distance between the horizontal section 9112 and the side surface of the stirring bowl 8 is 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.

[0140] In this embodiment, the distance between the axis of the stirring cage 91 and the axis of the stirring bowl 8 is 50-60 mm, and the distance between the vertical section 9111 and the rotation axis of the stirring cage 91 is 45-50 mm.

[0141] 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 the embodiment, the maximum radius of the stirring cage 91 is 47mm, so that the stirring range of the stirring cage 91 can cover the radius range of the stirring bowl 8 as much as possible, and the contact range of the stirring cage 91 and the liquid food material in the stirring bowl 8 is improved. 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 the embodiment, the distance between the axis of the stirring cage 91 and the axis of the stirring bowl 8 is 55.6mm.

[0142] As shown in Figure 22 , the rotation directions of the stirring bowl 8 and the stirring cage 91 are the same. That is, the rotation directions of the stirring bowl 8 and the stirring cage 91 are both counterclockwise or both clockwise, so that the liquid food material stirred by the stirring cage 91 can return to the stirring range of the stirring cage 91 along with the rotation of the stirring bowl 8, and the moving speed of the liquid food material is improved, and the stirring efficiency is improved.

[0143] As shown in Figure 22 , the bottom surface of the stirring bowl 8 is convexly provided with a convex 81, and the highest point of the convex 81 is located on the rotation axis of the stirring bowl 8. In the vertical direction, the projection part of the scraper 71 on the bottom surface of the stirring bowl 8 is located in the convex 81. It can be understood that, along the radial direction of the stirring bowl 8, the moving speed of the liquid food material close to the side wall is higher, and the moving speed of the liquid food material close to the center is close to zero, resulting in that the liquid food material close to the center is difficult to be thrown to the position of the stirring cage 91. The convex 81 can make the liquid at the center position flow along the convex 81 under the action of gravity, and when the liquid food material is less, the convex 81 can avoid the liquid food material from stopping at the center position of the stirring bowl 8, and ensure that the liquid food material can move to the concave part 714 of the scraper 71 along with the rotation of the stirring bowl 8.

[0144] As shown in Figure 23 and Figure 24 , the scraper assembly 7 further comprises a connecting shaft 72 fixedly connected with the scraper 71, the axis of the connecting shaft 72 is parallel to the rotation axis of the stirring cage 91, and the rotation axis of the stirring cage 91 and the connecting shaft 72 are both located on the same side of the rotation axis of the stirring bowl 8. This structure makes the scraper 71 be able to gather the food material on one side of the rotation axis of the stirring bowl 8, so as to facilitate the stirring cage 91 to fully stir the food material.

[0145] Specifically, the distance between the connecting shaft 72 and the rotation axis of the stirring bowl 8 is 5-10 mm. The distance needs to be smaller than the radius of the convex 81 to ensure that the scraper 71 can be partially located in the range of the convex 81 to improve the scraping effect of the scraper 71, so that the scraper 71 can scrape and gather all food substances on one side of the rotation axis of the stirring bowl 8.

[0146] As shown in Figure 25 , the stirring bowl 8 is provided with an upper cover 82, and the upper cover 82 is buckled on the stirring bowl 8 to prevent liquid food substances from splashing out of the stirring bowl 8 during stirring and polluting the environment.
